Background technique

Skiing, including alpine skiing, Nordic skiing and telema skiing, is a popular winter recreational activity or sport around the world. Equipment used while skiing includes boots, skis, and bindings that attach the boots to the skis. Ski boots, such as alpine ski boots, typically have shells made of rigid materials, such as various rigid polymers. Due to the rigid polymer material, the shell is often difficult to close around the user's legs and feet. It’s also often difficult to make ski boots comfortable due to their rigid materials. The right balance between comfort and fit in a ski boot is required, but this can be difficult to achieve due to the rigid materials used and other design constraints. Traditional closures used to close ski boots typically tighten the boot in relatively large increments or progressions, which can add a level of complexity when achieving the proper balance between fit and comfort. This article describes components, systems, and devices that enable quick and easy closure of ski boots, other boots, or items of footwear. These components, systems and devices balance comfort and fit while tightening the article of footwear around the wearer's foot. These components, systems and devices may also be used to close and tighten a variety of other non-footwear related items.

Contents of the invention

This article describes components, systems, and devices that enable quick and easy closure of ski boots, other boots, or items of footwear. These components, systems and devices balance comfort and fit while tightening the article of footwear around the wearer's foot. These components, systems and devices may also be used to close and tighten a variety of other non-footwear related items.

According to one aspect, a ski boot includes a rigid shell having a lower shell and an upper sleeve. The lower shell is configured to couple with the ski binding and receive the wearer's feet. The upper sleeves are pivotally coupled to the lower shell and are configured to accommodate the wearer's lower legs. The tightening system is connected to the lower shell. The tightening system includes a scroll-based closure coupled to the lower shell adjacent the upper sleeve. The tightening system may be the only tightening device attached to the lower housing. In other words, the lower shell may not include any other tightening means to close and tighten the lower shell around the wearer's foot.

The tensioning member is operatively connected to the reel-based closure such that operation of the reel-based closure effects tightening of the tensioning member to close and tighten the lower shell about the wearer's foot. The first guide is positioned on a first side of the opening of the lower housing and the second guide is positioned on a second side of the opening of the lower housing. The end member is coupled to the lower housing adjacent the toe box. The first and second guides route or guide the tensioning member along a path around the lower housing across the opening and to the end member. The distal end of the tensioning member is fixedly coupled to an end member that secures the tensioning member to the ski boot.

The first guide may be a long guide, the longitudinal length of which is significantly greater than the transverse width of the guide. The proximal end of the elongated guide may be attached to the lower shell near the sole of the lower shell, while the distal end of the elongated guide is positioned near the opening. The distal end of the elongated guide can engage the tensioning member. The second guide may be a short guide whose longitudinal length is significantly shorter than that of the long guide. In such an arrangement, the tightening system may further include a third guide positioned on the first side of the opening of the lower housing. The third guide may also be a long guide and have a similar construction to the first guide. The first, second and third guides may be arranged around the lower housing such that the second guide is positioned along the path between the first and third guides.

The housing of the reel-based closure may include a single access port or hole for the tensioning member. In other words, the housing may not include any other inlet port or hole for the tensioning member other than this single inlet port/hole. The housing of the reel-based closure may be removably coupled to the base member secured to the ski boot by a spring member. Reel-based closures may include gear mechanisms that amplify input torque or force. The reel-based closure may also be configured to gradually release the tensioning member upon a first operation of the reel-based closure, and to fully release the tensioning member upon a second operation of the reel-based closure. The second operation of the reel-based closure is generally different from the first operation of the reel-based closure.

The end member includes a locking component configured to engage and disengage the tensioning member. When the locking component is engaged with the tensioning member, the locking component fixedly couples the tensioning member to the end member. The locking component allows the tensioning member to be removed from the end member when the locking component is disengaged from the tensioning member. The end member may be configured so that when the tensioning member is coupled with the locking member, the tensioning member is positioned within a channel surrounding a through hole of a coupling bolt that secures the end member to the ski boot.

According to another aspect, an elongated guide for routing or guiding a tensioning member about an article includes a body having a transverse width, a longitudinal length substantially greater than the transverse width, and a channel formed at a distal end of the body. The channel is shaped and sized such that the tensioning member can be inserted therethrough. The elongated guide also includes a reinforcing member coupled to the main body. The reinforcing member supports or reinforces the channel formed in the distal end of the body. The reinforcing member may extend from the proximal end of the body to a channel formed in the distal end of the body. The channel may be formed in a guide section disposed within the annular end of the reinforcing member. The guide section may extend between opposite sides of the body to provide access to the tensioning member.

According to another aspect, a reel-based closure device for tensioning a tensioning member includes a housing, a spool rotatably positioned within the housing, and a dial or knob operably coupled with the spool such that the dial or The rotation of the knob rotates the spool in the tightening direction, thereby winding the tensioning member around the spool. The housing may be detachably coupled by a spring member to a base member securable to the article. The reel-based closure may include a gear mechanism that amplifies the input torque or force of the dial or knob, and/or the reel-based closure may be configured to gradually loosen the tensioning member upon a first operation of the dial/knob. , and a second operation based on the dial or knob to completely loosen the tensioning member. The housing may include only one lacing port or opening for the tensioning member.

According to another aspect, a boot includes a lower portion configured to receive a foot and an upper portion extending upwardly from the lower portion and configured to receive a calf. The boot also includes a tightening system coupled to the lower portion. The tightening system includes a reel-based closure and a tensioning member operatively coupled with the reel-based closure such that operation of the reel-based closure effects tensioning of the tensioning member. The tightening system also includes an end member that routes or guides the tensioning member along a path and a plurality of guide members that are fixedly coupled with the distal end of the tensioning member.

The plurality of guide members may include first and third guides positioned on a first side of the boot, and a second guide positioned on a second side of the boot opposite the first side. The first guide and the third guide may each have a longitudinal length greater than a longitudinal length of the second guide. The first, second and third guides may be arranged around the boot such that the second guide is positioned between the first and third guides along the path. The second guide may include an open channel within which the tensioning member is removably positioned.

Detailed ways

The ensuing description provides exemplary embodiments only and is not intended to limit the scope, applicability, or configuration of the invention. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing one or more exemplary embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims.

Embodiments herein describe reel-based closure devices that may be used to close or tighten items. Scroll-based closures may be particularly useful when closing and tightening items that require high lacing tension. For example, alpine boots or ski boots (hereinafter referred to as ski boots) are often made of rigid plastic materials that require considerable closing force to tighten around the user's foot. Traditional reel-based closures and other devices may not be suitable for tightening a ski boot around the user's foot because the reel-based closure may not be designed to output the required torque. Additionally, tensioning members or lacing used with ski boots may not be designed to handle the required tensioning forces.

The reel-based closures described here are better able to achieve high torque output and can be paired with tensioning members or ties designed to withstand higher tensioning loads. Therefore, reel-based closure devices may be well suited for closing and tightening items that require considerable closing force. In addition to tightening ski boots, scroll-based closures can also be used to close and tighten a variety of other items, such as snowboard boots, combat boots, shoes, bags, bags, and more. Additionally, reel-based closures can be used to close and tighten a variety of items that do not require high levels of closing force. In this case, the reel-based closure may be used unmodified, or one or more components of the reel-based closure may be modified or changed to enable use in another application. For purposes of describing embodiments herein, the scroll-based closure device will be generally described as being used to close and/or tighten ski boots, however it will be appreciated that this description applies equally to a variety of other items.

Roller-based closures are typically attached to the exterior of a ski boot, such as a shell, and are used to tighten the exterior of the ski boot around the user's legs and/or feet. The reel-based closure is configured to tighten a lacing or tensioning member that is guided around the ski boot through one or more guide members, which may be made of plastic or other materials, such as those described herein ) made of rigid components. In other embodiments, the one or more guide members may be made from a flexible or soft component, such as a fabric material.

Reel-based closures typically include a knob or dial that can be grasped and rotated by the user. The knob or dial is typically coupled to a spool around which the tensioning member or tie is wound in response to rotation of the knob or dial in the tightening direction. Rotation of the tensioning member or lace around the spool tightens the tensioning member or lace, which tightens the ski boot around the user's foot by causing the outer shell and any internal components (i.e., lining, etc.) to contract around the user's foot. Tighten.

Scroll-based closures may replace traditional buckles and/or other tightening systems currently used on ski boots to tighten the boot around the user's foot. In some embodiments, reel-based closures may be used in conjunction with traditional buckles or other tightening systems. Likewise, a ski boot may include multiple scroll-based closure devices arranged to close and tighten different areas or portions of the ski boot.

Reel-based closures are significantly easier to operate than traditional buckles and/or other tightening systems. Therefore, users may prefer to use a reel-based closure to tighten their ski boots. Additionally, the reel-based closure may provide an incremental degree of tightening and loosening of the ski boot compared to traditional buckles and/or other tightening systems. For example, conventional buckles and/or other tightening systems typically include a limited number of tightening segments (eg, teeth, steps, racks, etc.) for tightening ski boots. For example, traditional buckles typically employ 5 to 10 teeth on a rack with engagement pins positioned within the rack to tighten ski boots. The engagement pin moves proximally or distally around the rack and is positioned within the proximal or distal teeth to increase or decrease the tightness of the ski boot around the foot. A limited number of tightening segments (eg, teeth) causes the ski boot to be tightened or loosened by a greater amount or degree, so it may be difficult to achieve the desired fit.

In contrast, scroll-based closures are capable of tightening and/or loosening the ski boot in significantly smaller increments or degrees. For example, if a slight increase in tightness is desired, the knob of the spool-based closure may be turned a quarter turn, an eighth turn, or less to slightly increase the tensioning force in the tensioning member. A slight increase in the tensioning force of the tensioning member usually results in a slight increase in the tightness or constriction of the ski boot around the user's foot. This incremental adjustment of the ski boot's tightness may allow the desired fit of the ski boot to be easily achieved.

Referring to Figure 1, an assembled perspective view of the reel-based closure device 100 is shown. Figure 2 shows an exploded perspective view of the reel-based closure device 100. 3A-11B illustrate various views of the components of the reel-based closure device 100. Throughout this disclosure, reference will be made to the various figures illustrating a reel-based closure device 100 .

Figure 1 shows a base member or detent 102 designed to be attached to the housing 202 of the reel-based closure device 100. The base member 102 is designed to be attached to a ski boot shell (not shown) by mechanical fastening, gluing, molding, or using any other fastening technique. In one particular embodiment, the base member 102 may include one or more holes 103 (see Figure 8) that allow bolts, rivets, screws, or other mechanical fasteners to attach the base member 102 to the ski boot shell. The base member 102 is shown as including three holes 103, although more or fewer holes 103 may be used.

The base member 102 is generally a rigid material designed to withstand impact from external objects without breaking. In one particular embodiment, base member 102 may be made from glass-filled nylon, although various other rigid materials may alternatively be used. The base member 102 is designed to couple with the housing 202 in a manner that allows the housing 202 to be detached or removed from the base member 102 . Various methods of attaching the housing 202 to the base member 102 may be employed, but in the embodiment shown, a spring member is used to secure and couple the housing 202 to the base member 102 . The spring member is designed to flex when an object collides with the housing 202 to allow the housing to separate from the base member 102 thereby preventing the base member 102 and/or the housing 202 from breaking.

In some embodiments, the spring member may be a split ring or c-shaped spring 210. The base member 102 includes one or more arcuate or curved axially extending members 104 (see Figures 9A-9D) that define recesses or grooves where the c-shaped spring 210 is positioned when the housing 202 is attached to the base member. in this recess or groove. Housing 202 similarly includes a groove 260 (see FIGS. 3B and 8 ) that receives c-shaped spring 210 . The groove 260 of the housing 202 is shaped and sized such that the c-shaped spring 210 fits securely within the groove 260 . Groove 260 is defined by an upper annular lip or ring 262 and one or more radially projecting members 264. As shown in FIG. 8 , one or more radially projecting members 264 of the housing 202 are shaped and sized such that they are insertable within the openings 105 between opposing pairs of axially extending members 104 . The base member 102 includes a recess 108 on the circumferential edge that corresponds to the shape and size of the radially projecting member 264 . When the housing 202 is coupled with the base member 102 , the radially projecting member 264 is positioned within the recess 108 , which enables the grooves of the base member 102 to align with the grooves 260 of the housing 202 . In the embodiment shown, the housing 202 includes three radially projecting members 264 and the base member includes three axially extending members 104, although more or fewer of these features may be employed as desired.

Radially projecting member 264 and/or annular lip 262 extend radially outward from housing 202 such that when housing 202 is connected to base member 102 , the distal edge of radially projecting member 264 and/or annular lip 262 is in contact with the base member 102 . The distal ends are roughly aligned. In this manner, the housing 202 and the base member 102 may visually appear to be seamlessly integrated with each other. To further secure the c-shaped spring 210 to the housing, the lace port 266 of the housing 202 may include a pair of circumferentially extending holes (not shown) positioned on opposite ends of the groove 260 . The pair of circumferentially extending holes are shaped and sized such that opposing ends of the c-shaped spring can be positioned within the holes.

The c-shaped spring 210 is designed to flex radially to enable attachment and detachment of the housing 202 from the base member 102 . For example, as shown in FIGS. 9A-9B , to attach housing 202 to base member 102 , c-shaped spring 210 flexes such that the diameter of the c-shaped spring widens and conforms to axially extending member 104 and fit into the groove of the base member 102 . The widening of the diameter of the c-spring also allows the c-spring 210 to fit within the groove 260 of the housing 202 .

To allow the housing 202 to be removed from the base member 102, the axially extending member 104 is designed so that the c-shaped spring 210 can deflect out of the groove. Specifically, the axially extending member 104 is curved near the tip 106 such that the diameter of the tip 106 of the axially extending member 104 is greater than the diameter of the groove of the axially extending member. The larger diameter tip 106 of the axially extending member 104 helps secure the c-spring 210 within the groove, while the curved or arcuate design allows the c-spring 210 to easily deflect out of the groove. When an upward force is exerted on the housing 202, such as when the housing 202 strikes an object or a housing removal tool is applied, the c-shaped spring 210 is forced upward within the groove of the base member. As shown in FIGS. 9C-9D , the curved inner surface of the axially extending member 104 acts as a ramp and causes the c-shaped spring 210 to move axially upward relative to the base member 102 when the c-shaped spring 210 and the housing 202 move upward. Deflect radially outward. If the force is strong enough, the c-shaped spring 210 will deflect sufficiently and will move out of the groove, as shown in Figure 9D, which detaches the housing 202 from the base member 102 and enables the housing 202 to move upward and away from the base member 102 contacts. By changing the angle of the inner surface of the axially extending member 104 and/or the stiffness of the c-shaped spring, the force required to release or detach the housing 202 from the base member 102 can be changed.

To remove the housing 202 from the base member 102, the base member is designed to work with a housing removal tool. Specifically, the housing includes a support 109 for the tether outlet component 160 . The support 109 is shaped and sized according to the lace outlet component 160 in order to strengthen the lace outlet component 160 . A radially extending groove 107 is formed in the support 109 which enables a housing removal tool (not shown), such as a small flat head screwdriver, to be inserted along the groove 107 and under the housing 202 . With the housing removal tool positioned within groove 107 and below housing 202 , the housing removal tool can exert an upward force on housing 202 to detach housing 202 from base member 102 .

As shown in FIG. 2 , a coupling component or member 120 may be positioned between the base member 102 and the housing 202 . The coupling member 120 is designed to attach to the bottom end of the housing 202 and is shaped and sized such that the bottom end of the coupling member 120 is positionable within the interior region of the base member 102 . As shown in FIGS. 10A-10B , the shape and size of the coupling member 120 corresponds to the shape and size of the bottom end of the housing 202 . Specifically, the bottom end of the coupling component 120 is generally circular in shape, and is sized so that the coupling component 120 can be inserted into the circular opening of the bottom end of the housing 202 . To attach the coupling member 120 to the housing 202 , the coupling member 120 includes upwardly extending tabs 128 that snap into corresponding slots 205 forward at the bottom end of the housing 202 . The upwardly extending tabs 128 include radially outwardly extending tabs that snap or clip into recesses within corresponding slots 205 , which secure the coupling member 120 to the housing 202 . The coupling member 120 is shown as including two tabs 128, but more or fewer tabs may be used as desired. The front portion of the coupling member includes radially extending tabs that fit into corresponding features on the housing 202 . The bumps assist in the alignment and securing of the coupling member 120 about the housing 202 . The bottom end of the coupling member also includes one or more holes (not labeled) that correspond in size and orientation to the holes 103 in the base member 102 . The holes in the coupling component 120 allow the coupling component to fit over mechanical fasteners (eg, bolts) inserted into the holes 103 in the base member 102 , which reduces the overall height of the reel-based closure 100 . Coupling component 120 also includes one or more lacing holes 126 that may be aligned with lacing ports 136 in spool 130 to enable a tensioning member to be easily coupled with spool 130 as described herein.

The boss 125 extends axially upward from the bottom end of the coupling member 120 . When the coupling component is attached to the housing 202 , the boss 125 projects axially upward into the interior area of the housing 202 . Boss 125 includes a pair of fingers separated by a gap. The boss 125 , and more specifically the pair of fingers, is used to enable the turntable core 230 to move axially upward and downward relative to the housing 202 . Strengthening springs 122 are positioned in the gaps between the pair of fingers and serve to strengthen and reinforce the pair of fingers. The reinforcing spring 122 helps to elastically deflect the pair of fingers as the turntable core 230 moves axially upward and downward about the boss 125 . The reinforcing spring 122 can stiffen the pair of fingers and prevent the pair of fingers from plastic deformation due to long-term use of the closure device 100 . Reinforcement spring 122 includes holes that engage small protrusions on the inner surface of the pair of fingers. The engagement of the holes and protrusions locks or holds the reinforcing spring 122 in place relative to the pair of fingers.

The spool 130 may be positioned within the bottom end of the housing 202, typically by inserting the spool 130 into the open bottom end of the housing. The spool 130 includes a central hole 132 through which the boss 125 of the coupling member 120 passes. The spool 130 is configured to rotate about the boss 125 in both clockwise and counterclockwise directions with minimal frictional engagement between the two components. The gear mechanisms (140, 142), drive member 150, and turntable core 230 are also generally configured to rotate about the boss 125 in both clockwise and counterclockwise directions. The spool 130 includes a channel 133 within which a tensioning member (not shown) is wound as the spool 130 is rotated in a tightening direction (eg, clockwise). The tensioning member similarly unwinds around central channel 133 as spool 130 rotates in the unwinding direction (eg, counterclockwise). The width of the central channel 133 is slightly larger than the width of the tensioning members, which ensures that the tensioning members are wrapped around the central channel 133 as a "single stack", meaning that the wrapped tensioning members form a single layer within the channel 133. The single stacked winding of the tensioning member limits the vertical forces that the tensioning member could generate if it were coiled on the spool in an uncontrolled manner, and protects the tensioning member from damaging itself during the winding process. Given the considerable tensioning forces that the closure device 100 is capable of generating, wrapping the tensioning member around the spool 130 in an uncontrolled manner may result in excessive kink and/or damage to the tensioning member.

As briefly discussed above, the turntable core 230 is axially movable relative to the housing 202 . Movement of the turntable core 230 relative to the housing 202 enables the tensioning member to be fully released, which means that the spool 130 is able to rotate in the release direction in a relatively unconstrained manner. The "full release" feature is an optional feature that may be omitted in some embodiments of closure device 100. To enable complete release of the tensioning member, the closure device 100 is designed to move or transition between an engaged state or position in which the turntable core 230 is operably coupled with the spool 130, and a disengaged state or position. , in the disengaged state or position, the turntable core 230 is operably separated from the spool 120 . Transition between these two states is achieved by axial movement of the turntable core 230 relative to the housing 202 . Axial movement of the turntable core 230 relative to the housing 202 is typically accomplished by pulling axially upward on the knob 302 . However, in other embodiments, the turntable core 230 may be moved axially upward by counter-rotation of the knob 302 or by operation of a button (not shown), a lever mechanism (not shown), a clamp (not shown), or the like. move. In such embodiments, to move the turntable core 230 axially upward, the knob 302 and the turntable core 230 may include a cam, a ramp, or an inclined surface, or another mechanism, when the knob 302 is rotated in the release direction or when The cam, ramp or inclined surface, or another mechanism causes the turntable core 230 to move axially upward when a button, lever mechanism, etc. is operated.

As shown in FIGS. 4A-4B , the boss 125 is designed to cooperate with the turntable core 230 to support and maintain the turntable core 230 in the engaged position or the disengaged position. Specifically, the top end of the boss 125 supports and maintains the turntable core 230 and/or the knob 302 in the engaged and disengaged positions via the annular protrusion or member 124 . In one embodiment, the engaged position is shown in Figure 4A and the disengaged position is shown in Figure 4B. In the engaged position, the turntable core 230 engages the clutch plate 220, which enables force to be transferred between the two components as described herein. In the disengaged position, the turntable core 230 is disengaged from the clutch plate 220, which allows the spool 130 to "idle" or rotate freely in the release direction within the housing 202. Similarly, in the disengaged position, one or more pawls 240 may be disengaged from the teeth 204 formed on or otherwise coupled to the housing 202 . In other embodiments, one or more pawls 240 may remain engaged with the teeth 204 in the disengaged position.

The diameter of the annular protrusion 124 is larger than the diameter of the central opening 234 of the turntable core 230 , which causes the annular protrusion 124 to interfere with and hinder the upward and downward movement of the turntable core 230 around the top end of the boss 125 . Although the annular protrusion 124 resists axial movement of the turntable core 230, the annular protrusion 24 does not prevent axial movement of the turntable core 230 due to the ability of the fingers of the boss to shift or flex radially inward. As the turntable core 230 moves axially about the annular protrusion 124, the pair of fingers flex inwardly toward each other, which allows the central opening 234 of the turntable core 230 to surround the annular protrusion 124 and to move axially upward or over the annular protrusion 124. Move Downward. After the turntable core 230 moves axially upward or downward about the annular protrusion 124, the pair of fingers elastically deflect outward to return to the undeflected configuration. In operation, the central opening 234 of the turntable core 230 is positioned above or below the annular protrusion 124 that supports and maintains the turntable core 230 and/or the knob 302 in the engaged or disengaged position. The reinforcing spring 122 increases the stiffness of the boss 125 and reduces fatigue on the boss 125 caused by the repeated movement of the turntable core 230 around the annular protrusion 124 .

The knob 302 is coupled to the housing 202 by axially aligning the knob 302 and the housing 202 and snapping the knob 302 onto the annular flange or rib 209 of the housing 202 . Specifically, the inner wall or surface of the knob 302 includes one or more protrusions 304 or radial lips that snap onto the housing when the knob 302 is pressed and moves axially downward relative to the housing. on the annular rib 209 of the body 202. The protrusion 304 of the knob 302 defines an inner diameter that is smaller than the outer diameter of the annular rib 209 . Therefore, when coupling knob 302 to housing 202 , the inner walls of knob 302 must flex outward to some extent and/or housing 202 must flex inward to some extent to allow knob 302 to surround housing 202 Move axially downward and snap onto the housing 202 . After the knob 302 moves axially downward, the protrusion 304 is positioned axially below the annular rib 209 of the housing 202 . Due to the interference between the protrusion 304 and the annular rib 209, separation of the knob 302 from the housing 202 by axial upward movement of the knob 302 is prevented or significantly hindered. Separation of the knob 302 from the housing 202 can be further hindered by designing the annular rib 209 and/or the protrusion 304 so that they do not naturally deflect outward when the knob 302 is pushed upward relative to the housing 202 . Additional details of the coupling of the turntable core 230, the knob 302, and the housing 202 are provided in U.S. Patent Application No. 14/991,788 entitled "Integrated Closure Device Components and Methods" filed on January 8, 2016. The entire disclosure of is incorporated herein by reference.

Housing 202 includes an annular ring or lip 206 disposed on the interior wall. The annular ring 206 acts as a partition and divides the housing 202 into upper and lower halves. The annular ring 206 is configured such that some components positioned in the lower half of the housing 202 contact and engage the bottom surface of the annular ring 206 , and such that some components positioned in the upper half contact and engage the annular ring 206 upper surface. Components positioned in the lower half of housing 202 include coupling component 120, spool 130, gear mechanism (140, 142) and drive component 150. Components positioned in the upper half of housing 202 include clutch plate 220 , turntable core 230 , one or more pawls 240 , and pawl disk 250 . The annular ring 206 blocks or impedes movement of these components into the other half of the housing 202 .

Gear mechanisms (140, 142) are operatively connected to spool 130. The gear mechanism (140, 142) increases the mechanical advantage of the closure device 100, which increases the torque output of the closure device 100 and increases the tensioning force that the closure device 100 can generate. The gear mechanism includes a sun gear 140 , a plurality of planet gears 142 and a ring gear 208 . Ring gear 208 may include teeth formed on the interior wall of housing 202 below annular ring 206 , or ring gear 208 may be a separate component coupled (eg, press fit, keyed, etc.) to the lower half of housing 202 . As shown in FIGS. 3A and 7 , sun gear 140 is coaxially aligned with and rests on spool 130 , while each planet gear 142 is rotatably positioned on a boss extending axially upward from an upper surface of spool 130 134 on. The sun gear 140 is axially higher than the planet gears 142 such that an upper portion of the sun gear 140 matingly engages spline teeth 154 formed on the lower cylindrical inner wall of the drive member 150 . Spline teeth 154 extend axially downward from an annular ring formed or positioned within the drive member 150 .

When the driving component 150 rotates in the tightening direction due to the rotation of the knob 302, the driving component 150 transmits rotational force to the sun gear 140 due to the cooperative engagement of the sun gear 140 and the spline teeth 154, thereby causing the sun gear 140 to tighten along the tightening direction. direction of rotation. Rotation of the sun gear 140 also causes the planet gears 142 to rotate about the boss 134 of the spool, which causes the planet gears 142 to move in a tightening direction within the housing 202 due to the engagement of the planet gears 142 with the ring gear 208 . Movement of the planet gear 142 in the tightening direction causes the spool 130 to rotate in the tightening direction due to the engagement of the planet gear 142 with the boss 134 of the spool.

In some embodiments, gear mechanisms (140, 142) may be omitted. In such embodiments, the drive member 150 may be directly connected to the spool 130 to transmit rotational force to the spool 130 . When the end application of the closure device 100 does not require significant tensioning force and torque output, it may be desirable to omit the gear mechanism. Removal of the gear mechanism may make the closure device 100 axially smaller, which may be preferred in some embodiments. The drive member 150 may be directly connected to the spool 130 via axially oriented teeth, spline teeth, or the like.

The drive component 150 is used to transfer force from components positioned above the annular ring 206 (ie, clutch plate 220, knob 302, etc.) to components positioned below the annular ring 206 (eg, spool 130, gear mechanism, etc.). In order to be able to transmit force, the drive member 150 is operably coupled with the clutch plate 220 . The drive member 150 includes outwardly facing splines 152 positioned on an upper surface of the drive member 150 . Splines 152 couple with corresponding teeth 224 on clutch plate 220 . The engagement of the splines 152 and teeth 224 allows torque to be transmitted through the clutch plate 220 and drive member 150 to the gear mechanism (140, 142) and spool 130.

In one embodiment, drive component 150 and clutch plate 220 are assembled together via a snap-fit coupling. Specifically, one or more radially outwardly extending tabs (not numbered) are positioned between a pair of teeth of the drive member's splines 152 . The one or more radially outwardly extending tabs are positioned over corresponding teeth 224 of the clutch plate 220 when the clutch plate 220 is coupled with the drive member 150 . Clutch plate 220 is snap-fit coupled with drive member 150 by coaxially aligning clutch plate 220 with drive member 150 and by pressing clutch plate 220 axially downwardly against drive member 150 . When the clutch plate 220 presses axially downwardly against the drive member 150 and when one or more teeth 224 of the clutch member move past corresponding outwardly extending projections, both components, the clutch plate 220 and the drive member 150 Deflected to a certain extent. Once assembled, when the clutch plate 220 moves axially upward relative to the drive member 150, the one or more radially outwardly extending tabs contact the corresponding teeth 224, which prevents separation of the two components.

As shown in FIG. 3B , the drive member 150 is positioned below the annular ring 206 and the clutch plate 220 is positioned above the annular ring 206 . When the two components are coupled together, the annular ring 206 is sandwiched between the two components, which essentially locks the housing 202, clutch plate 220, and drive component 150 together. Clutch plate 220 is designed to engage the top surface of annular ring 206 to prevent rotation of spool 130 in the release direction once the tensioning force in the tensioning member decreases to or below the tensioning force threshold. The tensioning force threshold is typically at or near the point in the tensioning member where minimal or no tensioning force exists. This point generally corresponds to the point at which the tensioning member has been completely unwound about spool 130 . Preventing rotation of the spool 130 in the unwinding direction prevents reverse winding of the tensioning member about the spool 130 once the tensioning member is at or near the zero tensioning force threshold, which prevents the tensioning member from kinking or tangling about the spool 130 .

As shown in Figures 3B and 6C, the annular ring 206 of the housing includes a plurality of depressions or teeth 207 (hereinafter referred to as recesses 207) that are circumferentially arranged and evenly spaced around the annular ring 206. Recesses 207 are configured to engage corresponding bumps or teeth 226 (hereinafter bumps 226 ) that are circumferentially positioned and evenly spaced about the outer edge or ring of clutch plate 220 . When the nub 226 engages the recess 207 on the annular ring 206 , the clutch plate 220 is prevented from rotating relative to the housing 202 and annular ring 206 . The engagement of the bump 226 with the recess 207 locks the clutch plate 220 in position relative to the annular ring 206 . As described herein, spool 130 is also prevented from rotating within housing 202 due to the coupling of drive member 150 to spool 130 and the coupling of clutch plate 220 to drive member 150 .

To engage the annular ring 206 , the clutch plate 220 moves axially downward inside the housing 202 . The clutch plate 220 is designed to move downward within the housing 202 only when the tensioning force in the tensioning member reaches or decreases beyond the tensioning force threshold. When clutch plate 220 is in the axially raised position (this position is shown in Figures 4A, 5A and 6B), bumps 226 and recesses 207 disengage. As shown, the bottom surface of the clutch plate 220 is positioned above the annular ring 206 so that the bumps 226 and recesses 207 disengage, which allows the spool 130 to rotate in the tightening and loosening directions. After the projection 226 and the recess 207 are engaged, further rotation of the spool 130 in the loosening and tightening directions is prevented.

As shown in Figures 5A and 6B, due to the engagement of the clutch plate 220 and the turntable core 230, the clutch plate 220 remains in the axially raised position. Specifically, clutch plate 220 includes upper teeth 222 that engage axial teeth 232 of turntable core 230 . The upper teeth 222 of the clutch plate extend axially upward from the upper surface of the clutch plate 220 , while the axial teeth 232 of the turntable core 230 extend downwardly from the lower surface of the turntable core 230 . The upper teeth 222 of the clutch plate and the axial teeth 232 of the turntable core may include a slightly tapered or angled configuration that biases the clutch plate 220 axially upward when the teeth are engaged. The tensioning force in the tensioning member promotes engagement of the upper teeth 222 of the clutch plate and the axial teeth 232 of the turntable core by biasing the clutch plate 220 for rotation in the release direction via the spool 130 and drive member 150 . The upper teeth 222 of the clutch plate and the axial teeth 232 of the turntable core remain engaged until the tensioning force in the tensioning member reaches or exceeds the tensioning force threshold, after which point the tensioning member no longer biases the clutch plate 220 Set and rotate in the direction of release. When the tensioning force in the tensioning member is reduced to near the tensioning force threshold, the engagement of the upper teeth 222 of the clutch plate and the axial teeth 232 of the turntable core begins to decrease, which allows the clutch plate 220 to begin to move relative to the turntable core. The portion 230 slides axially downward, as shown in Figure 6A.

At some point near the tensioning force threshold, the clutch plate 220 will slide downward and engage the annular ring 206, thereby preventing further rotation of the clutch plate 220, drive member 150, and spool 130, as described herein. To simply illustrate the various components, annular ring 206 has been omitted from Figure 6A. However, it should be appreciated that the positions of clutch plate 220, drive member 150, and turntable core 230 in FIG. 6A correspond to the position where clutch plate 220 would engage annular ring 206. As shown in FIGS. 4B and 5B , when the turntable core 230 moves axially upward, the clutch plate 220 can also move axially downward. Axial upward movement of the turntable core 230 forces the upper teeth 222 of the clutch plate and the axial teeth 232 of the turntable core to disengage. Due to the engagement of one or more radially outwardly extending protrusions of the drive member with corresponding teeth 224 of the clutch plate 220 , the clutch plate 220 is prevented from moving upward with the turntable core 230 . As shown in Figures 4B and 5B, the disengagement of the clutch plate 220 and the turntable core 230 allows the spool 130 to "idle" or rotate freely in the release direction within the housing 202 because the clutch plate 220 and the turntable core 230 are not Rotationally locked or coupled together.

In some embodiments, the bumps 226 and the depressions 207 may be designed so that the bumps 226 and the depressions 207 do not immediately engage when the clutch plate 220 moves axially downward and contacts the annular ring 206 . This configuration may allow the spool 130 to rotate freely in the unwinding direction as the turntable core 230 moves axially upward. For example, when the turntable core 230 moves axially upward as described herein, the clutch plate 220 is no longer engaged with the turntable core 230 and therefore the clutch plate 220 can move axially downward into contact with the annular ring 206 . In this case, the clutch plate 220 may contact the annular ring 206 even if the tensioning force is maintained in the tensioning member. In order to allow the spool 130 to rotate freely in the release direction when the clutch plate 220 contacts the annular ring 206, the bump 226 and the recess 207 may not engage in the locking manner described above. Rather, the bump 226 and the recess 207 may be designed such that the bump 226 tilts or moves out of the recess 207 as the spool 130 is rotated in the release direction, which prevents the spool 130 from being rotationally locked to the housing 202 . More specifically, bump 226 and recess 207 may have rounded or angled shapes that allow bump 226 to tilt or move out of engagement with recess 207 . In this case, when the knob 302 is rotated in the loosening direction and the tensioning member is near the tensioning force threshold, the bump 226 and the depression 207 are still able to engage. In this case, the turntable core 230 pushes or compresses the clutch plate 220 downward, which forces the bump 226 and the recess 207 to remain locked or engaged together, thereby preventing the clutch plate 220 and spool 130 from rotating in the release direction.

To enable the clutch plate 220 to move axially about the drive member 150, the drive member splines 152 and the clutch plate teeth 224 are configured to allow such axial movement as shown in Figures 6A and 6B. Specifically, the drive member spline teeth are axially elongated compared to the clutch plate teeth 224 , which allows the shorter clutch plate teeth 224 to be axially aligned within the channels or grooves formed between the spline teeth. slide.

After the projection 226 and the recess 207 are engaged, the closure device 100 is configured such that the knob 302 can be rotated in the release direction without affecting the rotation of the spool 130 . Specifically, as shown in FIG. 6A , the rear surface of the axial teeth 232 of the turntable core and the rear surface of the upper teeth 222 of the clutch plate are relatively inclined or beveled, so that the rotation of the turntable core in the releasing direction causes these rear surfaces to The surfaces engage and cause the turntable core 230 to jump over the clutch plate 220, which pushes or forces the clutch plate 220 downwardly as previously described. As further shown in Figure 6A, when the turntable core 230 is in the axially lowered position, the axial teeth 232 of the turntable core and the upper teeth 222 of the clutch plate overlap slightly, causing rotation of the turntable core in the tightening direction (via Knob 302) causes the turntable core and clutch plate 220 to re-engage, which pulls or biases clutch plate 220 into the axially raised position shown in Figure 6B and allows spool 130 to rotate in the tightening and loosening directions. The turntable core 230 and the clutch plate 220 are re-engaged as the clutch plate 220 resists rotation in the tightening direction due to the tightening force in the tightening member and/or the engagement of the clutch plate's bumps 226 with the annular ring's recesses 207 .

In some embodiments, the clutch plate's bumps 226 and annular ring's depressions 207 may be replaced by other friction components, such as rubber-type washers or materials, abrasive materials, adhesive materials, etc. As shown in FIG. 6C , the clutch plate bump 226 may be axially recessed from the bottom surface of the clutch plate 220 , which allows the clutch plate 220 to sit lower around the annular ring 206 . For example, bumps 226 may be formed or positioned on a circumferential ring or rim that is axially recessed from the bottom surface of clutch plate 220 . In some embodiments, the bottom surface of the clutch plate 220 may be generally aligned with the bottom surface of the annular ring 206 , and/or the bottom surface of the clutch plate 220 may be aligned with the bottom surface of the annular ring 206 when the clutch plate bumps 226 engage the annular ring recesses 207 . Contact the upper surface of the driving member 150 .

The turntable core 230 is configured to couple with the knob 302, typically through a snap-fit coupling. In some embodiments, the knob 302 includes an axially extending tab 310 configured to couple with a corresponding edge or lip 238 of the turntable core 230 . Each protrusion 310 includes a radially inward lip 312 shaped and sized to fit under a corresponding edge 238 of the turntable core 230 (see Figure 4A). The tab 310 is elastic, which enables the tab to snap into engagement with the edge 238 of the turntable core. The protrusion 310 is also strong enough such that an axially upward force exerted on the knob 302 (e.g., a user pulling the knob axially upward) is transmitted to the turntable core 230 and causes the turntable core 230 to axially move along with the knob 302 Move up. Therefore, the knob 302 and the turntable core 230 move essentially as a single component.

The inward lip 312 of the protrusion couples with the edge 238 of the turntable core in a manner that allows the knob 302 to rotate about the turntable core 230 to a degree that enables the knob 302 to rotate in the loosening direction to gradually loosen the tensioning force, As described below. To enable relative movement of the knobs 302, the edge 238 of the turntable core is sized slightly larger than the inward lip 312 of the tab. As shown in Figure 5A, the edge 238 of the turntable core is formed by recessing the peripheral edge of the turntable core 230, which creates a slot in which the protrusion 310 is positioned. The protrusion 310 has a circumferential width that is less than the circumferential width of the corresponding slot, which allows the protrusion 310 to rotate within the slot to a certain extent. The protrusion 310 may have a radial width corresponding to the width of the recess such that the outer surface of the protrusion 310 is generally aligned with the outer surface of the turntable core 230 when the protrusion 310 is coupled with the edge 238 of the turntable core. In one embodiment, the knob 302 includes four tabs 310 and the turntable core 230 includes four edges 238, although more or fewer tabs 310 and edges 238 may be used as desired. The tabs 310 and edges 238 of the turntable core are generally positioned proximate the corresponding detents 240, which enables the tabs 310 to engage the pawls 240, but the locations of the tabs 310 and edges 238 can vary as desired. With the turntable core 230 attached to the knob 302 , one or more pawls 240 , and the detent disk 250 are sandwiched between the knob 302 and the turntable core 230 .

The closure device 100 includes a tether outlet component 160 that is separate from and assembled to the housing 202 . The separation of the tether outlet component 160 from the housing 202 allows the tether outlet component 160 to be formed from a low friction and wear resistant material while high strength and impact resistant materials are used for the housing 202 . For example, the housing 202 may be made of a high-impact resistant material that is less abrasion-resistant, while the tether outlet component 160 is made of a high-abrasion-resistant material that is less impact-resistant. The wear-resistant material allows the tether outlet component 160 to work with tensioning members designed to withstand higher tensioning loads. The lace outlet component 160 allows this tensioning member to slide repeatedly over the surface of the component without experiencing excessive wear. As shown in FIG. 10A , the tether outlet component 160 includes a pin 164 designed to fit within a corresponding slot 166 in the housing 202 . Pin 164 may be a protrusion extending outwardly from the body of lace outlet component 160 . The tether outlet member 160 may be attached to the housing 202 by positioning the tether outlet member 160 beneath the housing and sliding the pins 164 axially upward into corresponding slots 166 in the housing 202 . The lace outlet component 160 includes a lace channel 162 within which the tensioning member is positioned such that the tensioning member can access the spool 130 within the housing 202 . The lace outlet component 160 is shaped and sized to correspond with the support 109 of the base member 102 .

As shown in FIGS. 10A-10B , coupling component 120 includes one or more lacing holes 126 that may be aligned with lacing ports 136 in spool 130 . The alignment of the lacing hole 126 with the lacing port 136 of the spool allows the tensioning member to be easily coupled with the spool 130 . For example, as shown in FIG. 10C , the spool 130 may be aligned inside the housing 202 such that the channel 137 of the spool 130 is aligned with the lace channel 162 of the lace outlet component 160 . When the channel 137 of the spool is aligned with the lace channel 162 of the lace outlet component, the tensioning member can be inserted into the lace channel 162 of the lace outlet component and through the channel 137 of the spool. The distal end of the spool's channel 137 forms an opening 138 designed to guide the tensioning member downwardly and through the lace port 136 . Insertion of the tensioning member through the channel 137 of the spool and through the lace port 136 causes the tensioning member to extend outwardly from the bottom end of the spool 130 . Where the tensioning member extends beyond the bottom end of spool 130, a knot may be tied in the tensioning member, or a separate component may be attached to the tensioning member such that retraction of the tensioning member causes the distal end of the tensioning member to Engage the opening 138 of the spool and prevent the tensioning member from retracting through the opening 138 . In this manner, the tensioning member can be easily coupled with the spool 130.

Aligning the tie hole 126 of the coupling member with the tie port 136 of the spool allows the tensioning member to extend through the spool 130 and through the coupling member 120 so that a knot can be tied in the tensioning member, or a separate piece can be attached to the tensioning member without having to detach the coupling member 120 from the spool 130. In some embodiments, spool 130 may include a single lacing port 136 while coupling component 120 includes a pair of lacing holes 126 . This design enables a single coupling component 120 to be used with the spool 130 regardless of whether the lace port 136 is located on the left or right hand side of the spool 130, depending on whether the spool 130 is designed to rotate in a clockwise or counterclockwise tightening direction. Adopt this structure. FIG. 10C shows a top cross-sectional view of spool 130 such that channel 137 is shown on the side of spool 130 opposite lace port 136 . The lace port 136 may be formed in the channel 133 of the spool by forming a semicircular groove in the top or bottom flange of the spool 130 or in both flanges of the spool 130 . The semicircular grooves may guide or direct the tensioning member toward the opening 138 as the tensioning member passes through the lace channel 162 of the lace outlet component.

Referring now to FIGS. 11A-11B , the coupling of one or more pawls 240 , pawl disc 250 , and turntable core 230 is shown. Also shown are the functions of one or more pawls 240, pawl disks 250, and knobs 302 in controlling the rotation of the spool 130. To facilitate coupling the one or more detents 240 with the turntable core 230 , the turntable core 230 includes one or more drive bosses 236 extending axially upwardly from a top surface of the turntable core 230 . Each drive boss 236 includes a recess 237 shaped and sized to receive the proximal end 244 of one or more pawls 240 . The recess 237 is designed to enable each pawl 240 to rotate in both clockwise and counterclockwise directions on top of the turntable core 230 . In one particular embodiment, both the recess 237 and the proximal end 244 of the pawl 240 are semicircular in shape. The proximal end 244 of the pawl 240 may engage or contact the wall of the recess 237 such that a force or load exerted on the pawl 240 is transferred to the drive boss 236 . In this manner, each drive boss 236 supports and strengthens the corresponding detent 240.

The turntable core 230 also includes one or more pivot bosses 231 extending axially upward from the top surface of the turntable core 230 . Each pivot boss 231 is coupled with a corresponding pawl 240 by inserting the pivot boss 231 into a hole located on the proximal end of the corresponding pawl 240 . The coupling of the pawl 240 and the pivot boss 231 enables the pawl 240 to pivot or rotate around the pivot boss 231 . In some embodiments, one or more pawls 240 may be integrated with the turntable core 230 . In such embodiments, one or more pawls 240 are generally configured such that they are moveable or rotatable about the turntable core 230 . For example, one or more pawls 240 may be compliant mechanisms and/or may be coupled with one or more compliant members or mechanisms.

The pawl disk 250 is coupled to the turntable core 230 by aligning the recess 254 of the detent disk 250 with the corresponding keying protrusion 233 of the turntable core 230 . The detent disk 250 can then be pressed down on the top of the turntable core 230 so that the keying protrusions 233 snap into the corresponding recesses 254 . In some embodiments, pawl disc 250 may be integrated with turntable core 230 and/or one or more pawls 240 . In such embodiments, the detent disk 250 should be configured to bias one or more detents 240 outwardly, as described herein. Separation of one or more pawls 240, pawl discs 250, and/or dial core 230 allows each component to be made from different materials, which may enable these components to be optimized for specific purposes. For example, the one or more pawls 240 may be made of a high stiffness material capable of withstanding relatively high forces, while a soft spring-like material is used in the pawl disc 250 to actuate or bias the one or more pawls 240 . The dial core 230 may be made of a material suitable for supporting and reinforcing the pawl disc 250 and one or more pawls 240 .

Pawl plate 250 includes one or more arms 252 extending outwardly from the body of pawl plate 250 . One or more arms 252 are flexible and positioned on top of the turntable core 230 such that the distal end of each arm 252 is positioned against the rear surface of the corresponding pawl 240 . Arm 252 is configured to provide a biasing force that squeezes or biases pawl 240 into engagement with teeth 204 formed on or otherwise coupled to housing 202 . More specifically, arm 252 biases pawl 240 such that the pawl rotates about pivot boss 231 to engage tooth 204 . In this manner, pawl disc 250 acts as a spring that compresses or biases pawl 240 into engagement with teeth 204 .

Each pawl 240 includes one or more teeth 242 positioned at the distal end of the pawl 240 . The one or more teeth 242 are shaped and sized such that they are engageable with the teeth 204 of the closure device 100 . More specifically, the one or more teeth 242 are shaped and sized such that they fit within the one or more teeth of the closure device 100 . Engagement of the one or more pawl teeth 242 with the closure teeth 204 prevents rotation of the turntable core 230 in the release direction (eg, counterclockwise in Figure 11A). Specifically, when the pawls 240 engage the teeth 204 and force is applied to the turntable core 230 in the release direction (via the tensioning member and spool 130), the one or more pawls 240 disable the one or more pawls 240. 240 is oriented in a rotational manner and coupled to the turntable core 230 . Therefore, one or more pawls 240 remain engaged with the teeth 204, which prevents rotation of the turntable core 230 in the tightening direction.

As described herein, due to the engagement of the turntable core 230 with the clutch plate 220, the drive member 150 and the spool 130, the spool 130 is prevented from rotating in the release direction. Due to the biasing force of the pawl disk 250, the pawl 240 remains engaged with the teeth 204 until the pawl 240 is moved out of engagement with the teeth 204 due to upward movement of the turntable core 230 or rotation of the knob 302 in the release direction. Additionally, the biasing force of the pawl disc 250 causes one or more pawls 240 to automatically re-engage the teeth 204 when the turntable core 230 moves axially downward or when rotation of the knob 302 in the release direction ceases.

To rotate the spool 130 in the tightening direction, the protrusion 310 is configured to engage the drive boss 236 of the turntable core. Specifically, the tabs 310 extend axially downwardly from the knob 302 and are positioned such that when the knob 302 is coupled with the housing 202 in the engaged position, each tab 310 is adjacent the drive boss 236 and between the pawl 240 and the tooth 204 between. As shown in FIG. 11A , when the knob 302 is rotated in the tightening direction (eg, clockwise in FIG. 11A ), the proximal end of each protrusion 310 contacts the distal surface of the drive boss 236 . Engagement of protrusion 310 with drive boss 236 causes rotational force to be transmitted from knob 302 to turntable core 230 as knob 302 rotates in the tightening direction, which causes turntable core 230 to rotate in the tightening direction. As described herein, due to the engagement of the turntable core 230 with the clutch plate 220, the drive member 150 and the spool 130, rotation of the turntable core 230 in the tightening direction causes the spool 130 to also rotate in the tightening direction. The orientation of the one or more pawls 240 on the turntable core 230 causes the one or more pawls 240 to deflect inwardly and jump over the teeth 204 as the turntable core 230 rotates in the tightening direction. When one or more pawls 240 jump over teeth 204, pawl disc 250 causes one or more pawls 240 to spring outward.

The protrusion 310 is also configured to allow the turntable core 230 to gradually rotate in the release direction. Specifically, when the knob 302 is rotated in the loosening direction (eg, the counterclockwise direction in FIG. 11B ), each protrusion 310 rotates within the interior of the housing 202 such that the distal surface of each protrusion 310 contacts and Engage the distal end of the corresponding detent 240. Further rotation of the knob 302 in the release direction causes the protrusion 310 to push, pivot or rotate the corresponding pawl 240 out of engagement with the teeth 204 . Disengagement of one or more pawls 240 from the teeth 204 momentarily unlocks the turntable core 230 from the housing 202 , allowing the turntable core 230 to release in the release direction in response to forces in the release direction from the spool 130 and the tensioning member. Instantaneous or gradual rotation in direction. More specifically, the tensioning load or force in the tensioning member is exerted on the spool 130 and is transmitted to the clutch plate 220 and the turntable core 230 due to their engagement with the spool 130 . When the turntable core 230 is unlocked from the housing 202, the tension load causes the turntable core 230 to rotate in the release direction.

As the turntable core 230 rotates in the release direction, each tab 310 disengages from the corresponding pawl 240 due to the biasing force from the pawl disc 250 and pivots or rotates back into engagement with the teeth 204 . One or more pawls 240 remain engaged with the teeth 204 until further rotation of the knob 302 in the release direction causes the tab 310 to push, pivot, or rotate the pawls 240 out of engagement with the teeth 204 again. In this manner, the turntable core 230 and the spool 130 can be progressively rotated in the loosening direction to loosen or reduce the tensioning force in the tensioning member.

The progressive engagement and disengagement of pawl 240 and tab 310 to enable rotation of spool 130 and turntable core 230 in the release direction may be referred to as "sweeping" pawl 240 out of engagement with teeth 204 . To facilitate "sweeping" the pawl 240 out of engagement with the teeth 204 , each pawl 240 may include a nub or protrusion 246 extending slightly outward from the surface of the pawl 240 . The distal end of each protrusion 310 may also include an angled or sloped surface. The angled or sloped surface of each tab 310 engages the nub or tab 246 of each pawl 240 and applies progressively increasing force to the pawl 240 , which reduces stress and wear on both components. . In some embodiments, the angled or sloped surface may be formed only on the upper portion of each protrusion 310 . In such embodiments, the lower portion of each protrusion 310 may include a radially inward lip 312 shaped and sized to fit under the corresponding edge 238 of the turntable core 230 .

The extent or amount of each loosening step may be equal to the distance between each tooth 204 or the distance between multiple teeth, as desired. As described herein, when the tensioning force in the tensioning member is near the tensioning force threshold, the clutch plate 220 will slide downward and engage the annular ring 206, which prevents the clutch plate 220, drive member 150, and spool 130 from Spin further. When clutch plate 220 is engaged with annular ring 206, further rotation of dial core 230 and knob 302 in the release direction is possible due to the construction of dial core 230 and clutch plate 220.

In the embodiment shown, closure device 100 may include four pawls 240, four tabs 310, and four arms 252. This configuration may be ideal for generating high torque and accommodating high tension loads. In other embodiments, more or fewer components may be used based on the specific application or needs, or based on the desired torque output.

Referring now to Figure 12, there is shown a ski boot 400 including the closure device 100 described above. Closure device 100 may be ideal for tightening ski boots 400 because it is capable of outputting high torque and producing high tightening loads, which are typically required to close and tighten a ski boot around the user's foot. The ski boot 400 includes a unique elongated guide 410 designed to accommodate high tensile loads and facilitate closure and tightening of the ski boot shell. The elongated guide 410 is shown in greater detail in Figures 14A-14C. FIG. 13 illustrates a lacing path and guide configuration that may be employed on the ski boot 400 of FIG. 12 . Specifically, the guide configuration includes a plurality of long guides 410 and one or more shorter guides 460 positioned between a pair of long guides 410 . The closure device 100 is positioned at the top of the tether path, and the tensioning member 450 is routed along the tether path from the closure device 100 through a plurality of long guides 410 and one or more shorter guides 460. The tensioning member 450 terminates at the distal end of the tether path via an end member or terminal piece 470. The termination of the distal end of the tensioning member 450 enables the closure device 100 to generate greater tensioning forces in the tensioning member 450 .

The lacing path may extend across the opening between the two shells of the ski boot 400. In some embodiments, multiple long guides 410 may be positioned on one housing and one or more shorter guides 460 are positioned on an opposing housing. One or more shorter guides 460 may be riveted or mechanically fastened to the ski boot 400, while the distal end of the longer guide 410 is attached to the ski boot. One or more of the shorter guides 460 may have open channels or ends within which the tensioning members 450 are positioned, while the longer guides 410 include closed channels through which the tensioning members 450 are positioned. . The tensioning members may be removed or withdrawn from the open channels of one or more shorter guides 460 to allow the ski boot 400 to be more easily removed around the foot.

Referring to Figures 14A-14C, the longer guide 410 is made from multiple components. Specifically, elongated guide 410 includes a housing or body 412 and a reinforcing member 420 . Housing 412 houses reinforcement member 420 . The longer guide 410 enables the guide to be attached on the side of the ski boot 400 , typically near the sole of the ski boot, while the distal end of the engagement tensioning member 450 is positioned close to the opening of the ski boot 400 . This configuration helps the guide 410 wrap around the shell and promotes proper closure of the shell around the foot.

Reinforcement members 420 enable guide 410 to withstand high tensile loads without cracking or breaking. Reinforcement component 420 also allows housing 412 to be made from a low friction material that may not be able to withstand the tensioning forces exerted on tensioning member 450 . Housing 412 and reinforcement member 420 each extend from the proximal end of guide 410 to the distal end of guide 410 . The proximal ends of the shell 412 and reinforcement member 420 include holes 416 that allow rivets or other mechanical fasteners to attach the guide 410 to the ski boot 400 . Reinforcement member 420 is formed from a strip of material extending from the proximal end to the distal end of guide 410 . The material strip may be made of a metallic material, such as aluminum, or of another material capable of withstanding high tensile loads, such as fabric material, carbon fiber material, rigid polymer material, etc.

The strip of material is folded to form a looped end 422. The folded strip of material results in the reinforcing member 420 having upper and lower sections each extending from the annular end 422 to the proximal end of the guide. The upper and lower sections may each include an aperture 416 and may each be coupled to the ski boot shell. The upper and lower sections are generally positioned to contact each other from the proximal end of the reinforcement member 420 to the annular end 422, although in some embodiments the upper and lower sections may be separated by a housing 412 or another material.

Housing 412 includes a guide section 415 disposed within an annular end 422 of reinforcement member 420 . Guide section 415 extends between opposing sides of housing 412 . The distal end of the housing and the guide section 415 include a channel 414 through which the tensioning member 450 is positioned. The guide section 415 is made of a lower friction material than the reinforcement member 420, which minimizes the frictional engagement of the guide 410 and the tensioning member. When the guide 410 is tightened by the tensioning member 450, the guide section 415 presses against the annular end 422 of the reinforcing member 420. In this manner, some or all of the tensioning loads in the guide section 415 are transferred from the housing 412 to the reinforcement member 420, which can better handle the high tensioning loads generated by the closure device 100. The tensioning force in the annular end 422 is transferred to the proximal end of the guide 410 through the upper and lower sections of the strip of material of the reinforcing member and ultimately due to the mechanical fasteners anchoring the long guide 410 to the shell of the ski boot 400 Pass to the ski boot 400 shell. The tensioning force pulls the opposing shells together and pulls the ski boot closed over the user's foot. The long guide 410 is also pressed down on the top of the housing, which further closes and tightens the housing around the user's feet.

Housing 412 generally surrounds reinforcement member 420 . For example, the outer shell 412 may cover opposing sides of the reinforcement member 420, although in other embodiments, one or both sides of the reinforcement member 420 may be exposed. Housing 412 may also include a distal-most end positioned distal to annular end 422 . The distal-most end of the housing 412 may allow the tensioning member 450 to transition into and out of the channel 414 with minimal friction. For example, the opposite side of the distal-most end of the housing may be arcuate or curved and provide a smooth transition radius that eliminates the possibility of damaging the tensioning member 450 or creating excess on the guide segment 415 and/or annular end 422 Point of pressure. In some embodiments, the distal-most opposite side of the housing may have a radius of between 40 mm and 50 mm to provide a smooth transition to the tensioning member 450 . The most distal end may also cover the annular end 422 and prevent the annular end from contacting surrounding objects.

In some embodiments, the housing 412 may include one or more openings 418 through which the reinforcement member 420 is visible. For example, in the embodiment shown, the housing 412 includes two open portions through which the annular end 422 and the upper section are visible. The distal-most open portion may enable the reinforcement member 420 to be easily coupled to the housing 412 by allowing the upper and lower sections to be separated and positioned around the guide section 415 . The upper and lower segments can then be moved proximally until the annular end 422 is positioned around the guide segment 415. In other embodiments, the annular end 422 and/or the upper and lower sections may be covered by the outer shell 412 such that the reinforcing member 420 is not visible. The upper and lower sections may also be positioned on the bottom end or surface of the shell 412 so that the lower section contacts the shell of the ski boot 400 . In other embodiments, the upper and lower sections may be provided or enclosed within housing 412 as desired.

Housing 412 may include a pair of openings 418 separated by a bridge of material as shown in Figures 14A-14B, or housing 412 may include a single opening 418 as shown in Figure 14C. A bridge of material separating the pair of openings may be used to keep the upper and lower sections of stiffening member 420 in contact. In some embodiments, the length of the elongated guide 410 may be between 40 mm and 80 mm, more commonly between 50 mm and 70 mm. The width of the long guide can similarly be between 15mm and 35mm, more commonly between 20mm and 30mm. In particular embodiments, the elongated guide may have a length of approximately 60 mm and a width of approximately 25 mm. The elongated guide 410 may be curved about its longitudinal length to assist the elongated guide in engaging and contacting the upper surface of the ski boot shell. The shorter guide 460 may have a width corresponding to the width of the long guide and a length that is shorter than the width of the shorter guide 460 . The shorter guide 460 may not require reinforcing components because the mechanical fastener is positioned at the distal end of the tensioning member 450.

Referring to Figures 15A-15E, there is shown one embodiment of an end member or terminal component 470 (hereinafter referred to as end member 470) designed to be attached to a tensioning member 450. distally and attached to the ski boot 400 or any other item such that the tensioning member 45 is fixedly coupled or attached to the ski boot 400 or any other item. For ease of describing the end member 470, reference will be made to the end member 470 attached to the ski boot 400, although it will be appreciated that the end member 470 may be coupled to any desired item.

The end member 470 can be attached and detached from the ski boot 400, which allows for quick and easy replacement of the end member 470 if the tensioning member 450 fails or for any other reason. End member 470 includes a body 502 having an interior cavity 510 and a through-hole 508 . A through hole 508 is positioned on the proximal end of the body 502 and is shaped and sized such that a bolt 480 or other mechanical fastening device can be inserted through the through hole 508 and attached to the ski boot 400 . The upper portion of the through hole 508 may be recessed from the upper surface of the body 502 . The recessed portion of the through hole 508 may have a wider diameter than the remainder of the through hole 508 to allow the bolt 480 to be recessed relative to the upper surface of the body 502 thereby reducing the end member 470 when attached to the ski boot 400 Outline.

The body 502 also includes a lace port or hole 504 through which the tensioning member 450 passes, as described below. Tie hole 504 is positioned on the distal end of body 502 opposite through hole 508 . When end member 470 is attached to ski boot 400 , lacing hole 504 is positioned such that the opening of lacing hole 504 faces the lacing path of tensioning member 450 . The body 502 also includes an aperture 506 that enables a tool (not shown) to access a locking component 550 positioned within the cavity 510 of the body 502 . The tool, which may be a screwdriver or other device, may be inserted into hole 506 to engage locking member 550 and induce or release a locking force on tensioning member 450 . The locking force imparted or exerted on the tensioning member 450 by the locking member 550 is sufficient to lock or securely attach the tensioning member 450 to the end member 470 . Hole 506 is typically positioned on a side of body 502 that is generally perpendicular to tie hole 504; however, hole 506 may be positioned elsewhere around body 502 as desired. The positioning of hole 506 on a side of body 502 that is generally perpendicular to lacing hole 504 may be preferred because this allows the user to easily Access to hole 506 without interference from tensioning member 450 or other components of ski boot 400.

Figure 15C shows a bottom view of end member 470. The cavity 510 formed in the body 502 is evident in Figure 15C. In some embodiments, the cavity 510 has an L-shaped configuration to prevent the locking member 550 from being inserted into the cavity 510 in an incorrect orientation. Specifically, body 502 includes an elbow 514 that protrudes into a corner or portion of cavity 510 such that cavity 510 has an L-shaped profile when viewed from the bottom end, as shown in Figure 15C. A second cavity 512 is also defined in the bottom of body 502 adjacent lacing hole 504 . Second cavity 512 extends from cavity 510 and forms a small pocket or recess at the distal end of body 502 . As described below, the distal end of the tensioning member 450 is positioned within the second cavity 512 when the tensioning member is coupled with the end member 470 and the locking member 550 .

Channel 520 is formed in the proximal end of body 502 . Channel 520 extends from cavity 510 and around through hole 508 . Channel 520 is shaped and sized to correspond to the diameter of tensioning member 450 . More specifically, the width and depth of the channel 520 are greater than the diameter of the tensioning member 450 , which allows the tensioning member 450 to be positioned completely within the channel 520 and surround the bolt 480 positioned through the through hole 508 . In some embodiments, wall 522 extends from cavity 510 to, or adjacent to, through-hole 508 to divide a distal portion of channel 520 between cavity 510 and through-hole 508 into a first portion and a second portion. (Illustrated in Figure 15E as separate channels positioned laterally adjacent to each other). Wall 522 may be used to route or guide the tensioning member 450 as it is inserted into channel 520 and locking component 550 . In some embodiments, arrows or other symbols may be formed on the surface of channel 520. In the embodiment shown, arrows are formed in channel 520 around through hole 508 . The arrow may visibly indicate the direction in which the tensioning member 450 is to be routed through the locking component 550 and the channel 520 .

Figure 15C shows the locking component 550 positioned within the cavity 510 of the end member 470. Locking component 550 may include an L-shaped profile that mirrors the L-shaped profile of cavity 510 . Specifically, an elbow 559 may be formed in the locking component 550 that mates with the elbow 514 of the cavity 510 to enable the locking component 550 to be inserted into the L-shaped cavity 510 . The L-shaped cavity 510 and locking member 550 ensure that the locking member 550 is always properly or correctly inserted into the cavity 510 by preventing the locking member 550 from being inserted into the cavity 510 unless the locking member 550 is properly oriented and aligned with the cavity. 510 pairs of guidelines. Proper and correct insertion of the locking member 550 is important to ensure that the tensioning member 450 can be inserted through the locking member 550 in a manner that does not kink or damage the tensioning member 550 . For example, the locking component 550 includes a lace entry aperture 552 that is coaxially aligned with the lace aperture 504 of the body 502 when the locking component 550 is inserted into the cavity 510 . If the locking component 550 is not properly inserted into the cavity 510 , the lace entry hole 552 may be misaligned with the lace hole 504 of the body 502 , which may cause the tensioning member 450 to tighten around the ski boot 400 or the end member 470 to tighten around the boot 400 . The tensioning member 450 may become kinked or damaged when the ski boot 400 is assembled.

A lace entry hole 552 is formed on the distal side of the locking member 550 . A lace outlet hole 554 is formed on the proximal side of the locking member 550 opposite the lace inlet hole 552 . A channel or lumen extends between the tether inlet aperture 552 and the tether outlet aperture 554 , which allows the tensioning member to be fully inserted into the locking member 550 between the tether inlet aperture 522 and the tether outlet aperture 554 . When locking component 550 is positioned within cavity 510 , lace exit hole 554 is aligned with the first portion of channel 520 .

A second tether inlet hole 556 is formed on the proximal side of the locking member 550 , and a second tether outlet hole 558 is formed on the distal side of the locking member 550 opposite the second tether inlet hole 556 . When the locking component 550 is positioned within the cavity 510, the second tether inlet aperture 556 is aligned with the second portion of the channel 520 and the second tether outlet aperture 558 is aligned with the second cavity 512. A channel or lumen extends between the second tether inlet aperture 556 and the second tether outlet aperture 558 , which allows the tensioning member to be fully inserted into the locking member 550 between the second portion of the channel 520 and the second cavity 512 .

FIG. 15D shows a side view of the body 502 and, more particularly, the tool access hole 506 . A hole 506 is formed in the body 502 such that it extends from the cavity 510 to the outer surface of the body 502 . As briefly discussed above, a tool may be inserted through aperture 506 to engage locking member 550 positioned within cavity 510 of the body. The tool may be used to lock or unlock the tensioning member 450 from engagement with the locking member 550 that securely couples the tensioning member 450 to or releases the tensioning member 450 from the end member 470 . In one embodiment, the tool can access a set screw (not shown) threaded into the body of the locking component 550 . The tool can rotate the set screw into increased or decreased frictional engagement with the tensioning member 450. The set screw may exert a clamping or compressive force on the tensioning member 450 to lock the tensioning member 450 within the body of the locking member 550 , thereby fixedly attaching the tensioning member 45 to the end member 470 . More specifically, rotation of the set screw may move the set screw toward or away from the channel or lumen between the second tether inlet hole 556 and the second tether outlet hole 558, which may cause compression within the channel or lumen. Tensioning member 450. In some embodiments, a component or material, such as a nylon patch, may be positioned between the tensioning member 450 and the distal end of the set screw to minimize or eliminate undesirable damage to the tensioning member 450 by the set screw.

To securely couple or secure the tensioning member 450 to the locking component 550 , the tensioning member 450 passes through the lace hole 504 of the body 502 and through the lace entry hole 552 of the locking component 550 . The tensioning member 450 is then passed through the passage between the lace entry hole 552 and the lace exit hole 554 until the tensioning member 450 extends from the lace exit hole 552 . The tensioning member 450 then bends within the channel 520 around the through hole 508 along arrows formed or defined on the surface of the channel 520 . In some embodiments, wall 522 may be angled to help guide or deflect tensioning member 450 toward channel 520 as tensioning member 450 exits tether exit hole 554 . The tensioning member 450 is then passed through the second lace entry hole 556 and through the corresponding channel until the tensioning member 450 extends from the second lace exit hole 558 . Upon exiting the second tether exit aperture 558, the distal end of the tensioning member 450 is positioned within the second cavity 512. The set screw may then be engaged by passing the tool through the tool access hole 506 to lock the tensioning member 450 within the locking component 550 . Removal of the tensioning member 450 from the locking component 550 may be accomplished by accessing the set screw via a tool through the tool access hole 506 and rotating the set screw toward the unlocked position. The tensioning member 450 may then be removed from the locking component 550 and end member 470 . All of the above processes may be performed while the end member 470 is attached to the ski boot 400 .
