Description

adjustable booster chair

technical field

Various embodiments of the invention described herein relate generally to adjustable booster chairs for children and, more particularly, to adjustable booster chairs having a child support device with adjustable height and tilt . the

technical background

Children's booster chairs are commonly used to provide a raised seating surface for children. For example, many booster chairs are configured to be placed over an adult chair to provide a seating surface that is more suitable for supporting a child and is elevated above the seating surface of the adult chair. Such a booster chair is often used when feeding a child because it allows the child to sit in an elevated position closer to the table surface or more accessible to the parent. However, the preferred position of the child during feeding changes as the child grows. For example, a preferred seating position for an infant may be relatively high to accommodate the infant's small stature, and may be reclined since the infant may not be able to sit upright in the chair. Likewise, the toddler's preferred seating position may be lower to accommodate the toddler's taller height and less reclined as the toddler is able to sit upright. the

To provide a variety of seating positions for children of different ages and sizes, more recent booster chairs have been configured such that their height and inclination angle can be adjusted. For example, US Publication No. 2010/0181808 discloses a seat configured to swivel, recline and raise to accommodate a child during feeding. However, existing booster chairs provide these variable seat positions through the use of large, complex seat repositioning devices. Existing booster chairs are often too wide to accommodate these devices, making them difficult to fit on certain chairs (eg, adult chairs with armrests). Additionally, the complexity of these seat repositioning devices makes the booster chair expensive to produce, difficult to use, heavier to carry, and less reliable. the

Accordingly, there is a need in the art for an improved, adjustable children's booster chair that includes a simple, low-cost, reliable, lightweight, and easy-to-use means for adjusting the seating position of the booster chair. the

In particular, one or more tilt controls and height controls are positioned on the booster chair to allow a user to easily adjust the height and tilt of the child support device. The frame is also generally configured to have a narrow profile, thereby enabling the booster chair to be mounted on a wide variety of chairs. In some booster chair embodiments, such as those suitable for feeding infants, the booster chair further includes a removable tray and one or more booster chairs configured to securely secure the booster chair to the chair. belt. the

Figure 1 shows an adjustable booster chair 5 according to one embodiment. As shown in FIG. 1 , the adjustable booster chair 5 generally includes a frame 10 and a child support device 20 . In the illustrated embodiment, the frame 10 includes a base 102 , a pair of upright members 110 and a pair of vertically adjustable arms 120 . As described in more detail below, the vertically adjustable arms 120 are operably connected to the lateral sides of the child support device 20 and are configured to be selectively secured to the upright member 110 at different heights by a height control device. Inside. This function allows the height of the child support device 20 relative to the base 102 of the frame to be selectively adjusted by the user to a preferred position. Additionally, as described in more detail below, child support device 20 is operatively connected to vertically adjustable arm 120 such that child support device 20 is permitted to rotate about a generally horizontal axis. In particular, at least one of the vertically adjustable arms 120 includes at its interface with the child support device 20 a tilt control device 130 that enables the user to selectively position the child at different tilt angles relative to the frame 10. The child support device 20 is fixed. the

As shown in FIG. 1 , the child support device 20 includes a seat surface 202 having an upwardly extending bifurcated restraint post 203 and a removable backrest 204 . In the illustrated embodiment, the child support device 20 includes a seat formed from a generally rigid shell, and may include padding disposed on the seat surface 202 and backrest 204 to provide comfortable support for the child. However, according to various other embodiments, child support device 20 may comprise any suitable child support device capable of being secured to frame 10 as described herein (eg, a frame from which a fabric seat is suspended). the

In the illustrated embodiment, the base 102 of the frame is a generally rigid platform configured for resting on a support surface (e.g., the surface of a chair) and to provide a stable support base for the remaining components of the booster chair 5. . As described in more detail herein, the base 102 also defines a plurality of strap attachment points 104 , each of which includes one or more holes through which a securing strap can pass and attach to the base 102 . Additionally, as shown in the rear view of FIG. 6 , base 102 defines a transport handle 106 configured to be grasped by a user when transporting booster chair 5 . Additionally, in some embodiments, base 102 may be positioned on a swivel track or other swivel mechanism to enable a user to selectively swivel child support device 20 about a generally vertical axis of rotation. the

Upright members 110 of the frame extend upwardly from the lateral sides of the base 102 and are generally configured to support vertically adjustable arms 120 and thereby the child support device 20 . According to various embodiments, the upright member 110 may be a separate component attached to the base 102, or may be formed with the base 102 as a single molding. In the embodiment of FIG. 1, the upright members 110 of the frame are longer than they are wide, providing a relatively thin profile. Additionally, upright members 110 are positioned adjacent lateral sides of base 102 . In this way, the frame 10 is of narrow profile, having a reduced width, at least in the area where the frame 10 may be adjacent to the arm of the chair on which the booster chair is positioned. In these regions, the width of the frame 10 is approximately equal to the lateral distance between the outermost walls of the two upright members 110 . Because the width of the frame 10 is reduced, the booster chair 5 can be positioned on a variety of chairs, including chairs with armrests. For example, in one embodiment, the width of frame 10 between the outermost walls of upright members 110 is approximately 17.5 inches. the

As above, the upright members 110 and vertically adjustable arms 120 include height controls to effectively adjust the height of the child support device 20 . FIG. 2 shows a side cross-sectional view of one of the upright members 110 . As shown in FIG. 2 , the upright member 110 includes a generally vertical side wall 111 extending upwardly from the base 102 . The vertical side wall 111 defines an internal passage 112 having an upper opening 113 at the upper end of the vertical side wall 111. In the illustrated embodiment, the internal channel 112 extends downwardly into the base 102 . the

The upright member 110 includes two rows of teeth 114 at the lower end of its internal passage 112 . In the illustrated embodiment, each of the teeth 114 extends outwardly from the inner wall of the channel 112 and is angled slightly upward toward the upper opening 113 . Thus, each pair of adjacent teeth 114 defines an angled cavity 115 . As described in more detail herein, teeth 114 and cavity 115 are configured to engage a portion of a vertically adjustable arm 120 inserted into channel 112 as part of a height control device. the

FIG. 3 shows a side view of one of the vertically adjustable arms 120 . In the illustrated embodiment, the vertically adjustable arm 120 includes an elongated body 121 , an upper armrest 123 and a tilt control 130 . According to various embodiments, the elongate body 121 is a generally rigid member with a thin profile sized to fit within the interior channel 112 of the upright member 110 . As shown in FIG. 3 , the elongated body 121 includes a central protrusion 122 that protrudes slightly from the surface of the elongated body 121 and extends along the length of the elongated body 121 . The arm 120 further includes a pair of retractable fingers 125 extending outwardly from the sides of the central projection 122 of the body. As described in more detail below, the retractable fingers 125 can be actuated by a handle 126 (shown in FIGS. 1 and 4 ), which is disposed at the opposite end of the arm 120 . An upper armrest 123 is positioned adjacent the upper end of the elongated body 121 and extends outwardly from the elongated body 121 . As described in more detail below, some embodiments of armrest 123 are configured to accept and secure a tray of booster chair 5 . the

FIG. 4 shows a cross-sectional view of a vertically adjustable arm 120 of a frame positioned within one of the upright members 110 . According to various embodiments, arm 120 is configured to move vertically within upright member 110 and is selectively secured by a user at a preferred height. In particular, the handle 126 of the arm is configured to act as an actuation mechanism to enable the user to adjust the arm 120 between an adjustable configuration in which the arm 120 can be moved vertically within the upright member 110 and a fixed configuration, In the fixed configuration, the arm 120 is fixed within the upright member 110 at a user-preferred height. the

In particular, as shown in FIG. 4 , the retractable fingers 125 of the arms are positioned in lumens 128 within the vertically adjustable arms 120. Finger 125 is also operably connected to handle 126 by connecting member 127 . In the illustrated embodiment, the connecting member is a thin, elongated piece of plastic (eg, polypropylene tape). The handle 126 is biased towards the extended position by a resilient member 129 disposed between the upper end of the handle 126 and the upper edge of the vertically adjustable arm 120 . When the handle 126 is in its extended position (shown in FIG. 4 ), the connecting member 127 pushes the finger 125 out of the lumen 128 . Thus, when the fingers 125 are each aligned with one of the cavities 115, the fingers 125 extend into the cavities 115, as shown in FIG. When the fingers 125 are extended into the cavity 115 and engage the teeth 114, the vertically adjustable arm 120 is prevented from moving up and down, and thus is in a fixed configuration. That is, the handle 126 is generally biased toward an extended, fixed configuration in which the height of the vertically adjustable arm 120 relative to the upright member 110 is fixed. the

However, by pulling up on the handle 126, the user can actuate the arm 120 to an adjustable configuration in which the height of the arm 120 can be adjusted. As will be shown in FIG. 4 , when the handle 126 is pulled upwards, the elastic member 129 is compressed and the connecting member 127 pulls the fingers 125 upwards so that the fingers 125 are retracted back into the lumen 128 . With fingers 125 retracted and out of engagement with teeth 114 , arm 120 is free to move up and down within upright member 110 . In the illustrated embodiment, each row of teeth 114 defines four cavities 115 . Thus, using the handle 126, the user can selectively fix the arm 120 at one of four different heights. the

Since the child support device 20 is operatively connected to the vertically adjustable arm 120 , adjusting the height of the arm 120 relative to the upright member 110 necessarily adjusts the height of the child support device 20 . Thus, in the embodiment shown in FIG. 4, teeth 114, cavity 115, fingers 125, handle 126, connecting member 127, lumen 128, and resilient element 129 constitute a height control device configured to adjust the child's The height of the support device 20. the

According to other embodiments, a resilient member may be disposed within lumen 128 to bias fingers 125 and handle 126 toward the extended position. The elastic element thus positioned within the lumen 128 may be provided instead of the elastic element 129 shown in FIG. 4 , or simultaneously. Also, in other embodiments, additional teeth 114 may be positioned within channel 112 to provide additional height settings for vertically adjustable arm 120 . In yet another embodiment, the positions and orientations of the components of the height control device may be reversed. For example, in one embodiment, the teeth 114 and cavity 115 are defined on the elongated body 121 of the vertically adjustable arm 120, while the retractable fingers 125, handle 126, connecting member 127, lumen 128 And resilient elements 129 may be positioned on or within various portions of upright member 110 . the

In the embodiment shown in FIG. 1 , the height controls are positioned within the upright members 110 and vertically adjustable arms 120 on each side of the child support device 20 . Thus, in the illustrated embodiment, the user can position the child support device 20 by pulling the handles 126 on each side of the child support device 20, moving the two vertically adjustable arms 120 to a desired height and releasing the handles 126. The height of the child support device 20 is adjusted by fixing to a desired height. However, in other embodiments, only one height control device may be located (eg, within only one of the upright member 110 and arm 120 combinations, with the other arm 120 configured to move with the height-controlled arm 120 ). In other embodiments, additional height control means may be provided (eg, in additional upright members 110 and vertically adjustable arms 120). Additionally, as follows, the height adjustment device shown in FIG. 4 merely shows one embodiment of a height adjustment device suitable for use with booster chair 5 . Indeed, it is contemplated that other arrangements may be adapted to enable the vertically adjustable arm 120 to be adjusted and selectively secured by the user at various heights relative to the upright member 110 . the

FIG. 5 shows a cross-sectional view of the tilt control device 130 positioned on one of the vertically adjustable arms 120 . According to various embodiments, tilt control device 130 is configured to allow selective rotation of child support device 20 relative to arm 120 . As shown in FIG. 5 , the tilt control device 130 includes a rotating member 131 and a fixing member 132 . In the illustrated embodiment, the securing member 132 is attached to the elongate body 121 of the arm, just below the armrest 123 . the

The rotating member 131 is rotatably fixed on the fixed member 132 such that the rotating member 131 can rotate around the shaft 133 . In the illustrated embodiment, the axis 133 is generally perpendicular to the surface of the illustrated elongate body 121 and thus is generally horizontal, and will extend outwardly from the page of FIG. 5 . In addition, the rotation member 131 is attached at the lateral side of the child support device 20 . For example, FIG. 6 shows a rear view of booster chair 5 . As shown in FIG. 6 , the rotating member 131 is connected to the lateral sides of the child support device 20 just below the edge extending around the perimeter of the child support device 20 . the

To control rotation of the child support device 20, the securing member 132 includes a plurality of teeth 134 defining cavities 135 therebetween. The rotation member 131 includes a trigger member 136 connected to the rotation member 131 by a pin 137 such that the trigger member 136 can rotate about the pin 137 . The trigger member 136 also includes a finger 138 configured to engage the teeth 134 of the securing member (eg, by being positioned within one of the cavities 135 ). As shown in FIG. 5 , the trigger member 136 is positioned generally within the rotating member 131 , but includes an exposed surface near the upper end of the rotating member 131 such that the trigger member 136 can be actuated by a user. The exposed face of the trigger member 136 is also visible in FIG. 6 . the

According to various embodiments, the tilt control device 130 is configured to be actuated between a fixed configuration, in which the child support device 20 is prevented from rotating relative to the vertically adjustable arm 120, and an adjustable configuration. In configuration, child support device 20 is allowed to rotate about axis 133 . Figure 5 shows the tilt control device 130 in a stationary configuration. As shown in FIG. 5 , the rotating member 131 is prevented from rotating relative to the fixed member 132 when the finger 138 of the trigger member is positioned within one of the cavities 135 and thereby engages the tooth 134 of the fixed member. Accordingly, the child support device 20 attached to the rotating member 131 will not be allowed to rotate relative to the vertically adjustable arm 120 . the

To actuate tilt control 130 to the adjustable configuration, a user may press on the exposed face of trigger member 136 causing it to rotate about pin 137 , thereby causing its finger 138 to be moved out of tooth 134 . With fingers 138 disengaged from teeth 134 , rotating member 131 , and thus child support device 20 , is free to rotate about axis 133 . To drive the tilt control 130 back to the fixed configuration, the user may allow the finger 138 to realign with one of the fixed member cavities 135 and release the trigger member 136 so that the finger 138 re-engages the tooth 134 . In the embodiment shown in FIG. 5 , the securing member 132 defines three cavities 135 that allow the child support device 20 to be secured at three different angles relative to the vertically adjustable arm 120 . the

According to various embodiments, a resilient element may be disposed within the rotating member 131 to bias the trigger member 136 towards the fixed configuration. Additionally, the trigger member 136 may be sized such that when it is in the adjustable configuration and rotated by the user, the finger 138 jumps over the upper surface of the tooth 134 to provide the user with a "click" feel, which It is shown that the finger 138 has been realigned with a different cavity 135 . Also, the fixed member 132 may be positioned with additional teeth to provide additional tilt settings for the tilt control device 130 . In yet another embodiment, the positions and orientations of certain components of the tilt control device may be reversed. For example, in one embodiment, tooth 134 and cavity 135 are defined on trigger member 136 , while finger 138 is defined within fixation member 132 . Additionally, as will be shown in FIG. 6 , the rear end of the frame's base 102 extends further rearward than the amount the child support device 10 would extend rearward in its most reclined position. Accordingly, the base 102 can be placed on the chair such that its rear end contacts the seat back and prevents the child support 20 from contacting the seat back when the child support 20 is tilted. the

In the embodiment shown in FIG. 1 , one of the vertically adjustable arms 120 includes the tilt control 130 described above at its interface with the child support 20 , while the other vertically adjustable arm 120 does not have the tilt control 130 . Adjustable arm 120 is rotatably connected to child support device 20 . In such embodiments, a single tilt control device 130 can control the tilt angle of the child support device 20 . However, in other embodiments, an additional tilt control device 130 may be provided (eg, at the junction of the child support device 20 and the two vertically adjustable arms 120). the

As above, the child support device 20 also includes a removable backrest 204 . Returning to FIG. 6 , a removable backrest 204 is shown attached to the lower portion of the child support device 20 . In the illustrated embodiment, backrest 204 is configured to engage ridge 207 along child support device 20 and is removably secured by clip 206 . According to various embodiments, the backrest 204 may be removed to accommodate larger children (eg, children with wider shoulders than the backrest 204 ) or replaced with a removable backrest of a different size. the

Figure 7 shows the booster chair 5 with the tray 30 attached. According to various embodiments, the tray 30 is configured to be removably secured to the armrest 123 of the vertically adjustable arm 120 (eg, using a clip or other common attachment means). As will be shown in FIG. 7 , since the tray 30 is secured to the armrest 123 , the child support device 20 can be tilted forward and rearward independently of the tray 30 . That is, in the illustrated embodiment, the tray 30 does not tilt with the child support device 20 . In other embodiments, tray 30 may be configured to rotate about pins located at either end thereof. In such an embodiment, the armrest 123 may define a locking mechanism configured to receive and secure the pins of the tray and allow the tray to rotate about either pin. the

Additionally, certain embodiments of booster chair 5 include one or more securing straps configured to secure booster chair 5 to the chair. FIG. 8 shows the booster chair 5 secured to the chair 6 . In the illustrated embodiment, the booster chair 5 includes a plurality of straps 40 that are attached to strap attachment points 104 on the frame 10 . According to various embodiments, the securing strap 40 may include one or more fasteners (eg, side release buckles) to enable a user to quickly and easily secure the strap 40 around portions of the chair 6 . For example, as shown in FIG. 8 , strap 40 can be secured around the seat and back of chair 6 to secure booster chair 5 to chair 6 . the

According to various embodiments, the booster chair 5 shown and described herein provides a secure child support device having a height and inclination that can be easily adjusted by the user. In addition, the components of the booster chair 5 that provide this function can be easily assembled, have low manufacturing costs, and are very reliable. the
