DETAILED DESCRIPTION
[0018] Strollers typically include a frame and a seat supported by the frame to receive a child occupant. In some examples, an accessory, such as a basket, is also supported by the frame. However, some known strollers are limited with respect to a number of accessories that the stroller can support, and/or with respect to a number of seats the stroller can support. For example, some strollers include only one seat for one child. If a user wishes to carry a second child in the stroller, the user has to purchase a different stroller that includes two seats (e.g., a double stroller). However, a double stroller having two identical seats may not be appropriate if, for example, one child is capable of sitting upright but the other child cannot sit upright because of the child’s age. Also, a double stroller may be difficult to push if there is only one child in the stroller because of the extra unoccupied seat and/or uneven loading of the stroller. Thus, some known strollers do not provide for flexibility in accommodating different numbers of occupants and/or occupants of different ages.
[0019] Additionally, some known strollers are limited with respect to supporting an accessory (e.g., a bassinet, a side basket, etc.) alongside a seat (e.g., an infant car seat). In some known strollers, a specific connector type is utilized to attach an accessory or a seat to a stroller frame. For example, different manufacturers utilize unique connector types with unique geometries. Some strollers are configured to support only one of these connector types, depending on, for example, brand affiliations. As a further complication, accessories and seats may have different size factors, and in combination may not be simultaneously mountable within the traditional stroller frame.
[0020] While some known strollers offer the ability to include two seats, these are not removable and/or replaceable with other seats and/or accessories. Such a stroller would not be appropriate if, for example, one child is capable of sitting upright but the other child cannot sit upright because of the child’s age. In such an example, a bassinet may be desired next to a typical seat. Thus, some known strollers do not provide sufficient flexibility in accommodating different numbers of occupants, occupants of different ages/requirements, and/or combinations of seats and accessories.
[0021] Disclosed herein are example strollers for removably coupling one or more seats and/or accessories (e.g., a basket, a bassinet, and/or a car seat) to the stroller frame using an example laterally adjustable adapter. The example stroller frame includes different mounts that can receive different types of seats and/or accessories, such as an upright seat, a car seat, and/or a bassinet. Car seats and bassinets are interchangeably referred to herein as seats or accessories.
[0022] In the disclosed examples, one or more seats and/or accessories are removably coupled to the stroller frame without changing a size of the stroller frame. The one or more seats and/or accessories can be removably coupled to the stroller frame via the laterally adjustable adapter, which can be mounted to a receptacle on a mounting support member of the stroller frame. The laterally adjustable adapter includes a support tube, which carries connectors for mounting accessories and/or a seat. The lateral adjustability of the adapter enables the support tube to selectively translate between a plurality of lateral positions (e.g., left, center, right, etc.) when a lateral adjustment button on top of the adapter is pressed. By laterally adjusting one or more adapters, mounting combinations that would otherwise not be possible can be achieved. [0023] In some examples, static or non-laterally adjustable adapters may also be removably coupled to a receptacle on the mounting support member. The static adapter may also enable a variety of positioning combinations to suit different accessory and/or seat combinations. Therefore, in an example utilizing only static adapters, a position of the one or more seats or accessories removably coupled to the example stroller can still be varied with respect to a left position (e.g., the left receptacle), a center position (e.g., the center receptacle), or a right position (e.g., the right receptacle).
[0024] Example laterally adjustable adapters include connectors that may be of a plurality of different types (e.g., different shapes, sizes, and/or configurations for different manufacturers, etc.) to mount accessories and/or seats. Such connectors are removably coupled to the adapter and can be exchanged for a different connector to mount an accessory and/or seat requiring a different connector type. Example connectors disclosed herein enable accessories and/or seats to be mounted in either the forward-facing (e.g., facing the front wheels, away from the handle bar) or rearward-facing (e.g., facing toward the handle bar) direction.
[0025] Example adapters disclosed herein are selectively mountable to any of the receptacles on the mounting support member of the stroller frame using a latching end portion that is locked into a receptacle by engaging mating geometry of the receptacle. An example latch is connected to an example latch release section that protrudes from the adapter to enable a user to release the latch and remove the adapter from the locked position in the receptacle. In some examples, the receptacles have similar or complementary geometry, and the end portions of the adapters have similar or complementary geometry, enabling any adapter to be utilized in any receptacle.
[0026] Turning to the figures, FIG. 1 is a perspective view from the front and left side of an example stroller having two adapters coupled to a frame of the stroller in accordance with the teachings of this disclosure. The example stroller 100 illustrated in FIG. 1 includes a frame 102 having a first side 104 and a second side 106. The first side 104 and the second side 106 of the stroller frame 102 include a plurality of frame members and wheels attached to the frame members. The frame members and wheels of the first side 104 and of the stroller frame 102 will be described herein with the understanding that the second side 106 is a mirror image of the first side 104. In some examples, the second side 106 can have different geometry relative to the first side 104.
[0027] In the illustrated example stroller 100, the first side includes an example lower arm 108 and an example upper arm 110. In some examples, the upper arm 110 is extendible and able to translate parallel to the lower arm (e.g., telescopically) to provide an extended position of a parent handle 112. The parent handle 112 can be used to operate the stroller (e.g., navigate, move, etc.). The parent handle 112 is disposed between the first side 104 and the second side 106 of the stroller frame 102. In some examples, the upper arm 110 and the parent handle 112 are integrally formed from a unit such as, for example, a tube. The parent handle 112 includes a release 114 for enabling the stroller frame 102 to fold to a collapsed position when not in use. A cross-bar 116 is located below the parent handle 112 and is disposed between the first side 104 and the second side 106 to provide additional structural support to these sections of the stroller frame 102. In some examples, the stroller frame 102 does not include the cross-bar 116, or includes the cross-bar 116 disposed at a different height between the first side 104 and the second side 106.
[0028] The first side 104 of the stroller frame 102 also includes a front leg 118 and a rear leg 120. A front wheel 122 is rotatably coupled to the front leg 118. In some examples, the front wheel 122 is rotatably coupled to a front bar 124 that extends between the first side 104 and the second side 106. In some examples, the front bar 124 is connected to, or is part of, a foot mount 126. A rear wheel 128 is also coupled to the rear leg 120. In some examples, the rear wheel 128 is also coupled to a rear bar 130 that extends between the first side 104 and the second side 106. While the example stroller 100 of FIG.
1 includes four wheels (e.g., two front wheels 122 and two rear wheels 128 coupled to the first and second sides 104, 106 of the stroller frame 102), different numbers of front and/or rear wheels can be used (e.g., a single front wheel).
[0029] In the illustrated example, the front leg 118 and the rear leg 120 are coupled via a joint 132. The rear leg 120 and the lower arm 108 are coupled via a hub 134 (e.g., a second joint). The joint 132 and the hub 134 facilitate folding of the stroller 100 such that the front leg 118 and the arms 108, 110, and, thus, the parent handle 112, are free to rotate relative to the rear leg 120 when the stroller frame 102 moves between an expanded, open, or in- use position and a collapsed, closed, or storage position. [0030] In the example stroller 100, first and second joints 132 additionally connect to an example mounting support member 136. The mounting support member 136 is laterally disposed between the first side 104 and the second side 106. In the illustrated example, the mounting support member 136 includes example receptacles 140 for receiving example adapters 142A, 142B. While only one of the receptacles 140 is partially visible in FIG. 1, the example stroller 100 has an example mounting support member 136 with three example receptacles 140 (e.g., a left receptacle, a center receptacle, and a right receptacle). In some examples, the mounting support member 136 may include another number of receptacles 140 such as, for example, one, two, four, etc. Detail of the mounting support member 136 is further disclosed below in connection with FIG. 5.
[0031] In the example of FIG. 1, the example adapters 142A, 142B of the example stroller 100 are mounted in the left and right receptacles 140 of the mounting support member 136. In some examples, one of the adapters 142 A, 142B could be mounted to the center one of the receptacles 140, which is unused in the example of FIG. 1. The adapters 142A, 142B include an example support tube 144. The support tube 144 extends at a central portion in a direction parallel to the mounting support member 136 and extends perpendicular to the mounting support member 136 in an upward direction. The support tube 144 has an example first connector 146 A, 146B and an example second connector 148A, 148B removably coupled to respective first and second ends. The first connector 146A, 146B and the second connector 148 A, 148B can be any type of connector suitable to an accessory or seat for mounting to the stroller 100. Example connectors that can be removably coupled to the support tube are depicted in FIGS. 3A-3E.
[0032] The example adapters 142A, 142B include an adapter body 150 that includes a lateral adjustment mechanism to enable the support tube 144 to translate in the direction parallel to the length of the mounting support member 136 (e.g., laterally). In the illustrated example stroller 100 of FIG. 1, the support tube 144 of the adapter 142A that is closer to the second side 106 is positioned in a“left” position, with more of the support tube 144 extending out of the left side of the adapter body 150 than out of the right side of the adapter body 150. Conversely, in the illustrated example stroller 100 of FIG.
1, the support tube 144 of the adapter 142B that is closer to the first side 104 is positioned in a“right” position, with more of the support tube 144 extending out of the right side of the adapter body 150 than out of the left side of the adapter body 150.
[0033] FIGS. 2A-2C are front views of the adapter 142 A with the support tube 144 shown in three different lateral positions. While the adapter 142A is described, the same depiction of FIGS. 2A-2C and the associated description apply equally to the adapter 142B. Further, the same depiction and description apply equally to any example adapter 302, 308, 316, 320 of FIGS. 3B-3E. In the example adapter 142A of FIG. 2A, the support tube 144 is shown in the“left” position, wherein more of the support tube 144 extends out of the adapter body 150 on the left side than on the right side. An accessory and/or seat that is mounted to the first connector 146A and second connector 148 A would therefore be shifted to the left, relative to the position of the adapter body 150. The lateral adjustment mechanism that enables the adjustment of the position of the support tube 144, and subsequently the position of the first connector 146A and second connector 148 A and any mounted accessories or seats, is disclosed in further detail in connection with FIGS. 4 and 6-9.
[0034] In the example adapter 142 A of FIG. 2B, the support tube 144 is shown in the“center” position, wherein the support tube 144 is substantially centrally aligned within the adapter body 150 such that approximately equal amounts of the support tube 144 extend out from the adapter body 150 on the left side compared to on the right side. This configuration positions the first connector 146 A and the second connector 148 A generally equally spaced from the adapter body 150.
[0035] In the example adapter 142 A of FIG. 2C, the support tube 144 is shown in the“right” position, wherein more of the support tube 144 extends out of the adapter body 150 on the right side than on the left side. This configuration positions the first connector 146A closer to the adapter body 150 than the second connector 148A. The support tube 144 may be positioned in any of the positions shown in FIGS. 2A-2C or any position therebetween. In some examples, there are not discrete positions but, rather, an infinite number of lateral displacements can be achieved.
[0036] FIGS. 3A-3E are perspective views from the front and left side of the example adapter 142A of the example stroller 100 of FIG. 1 and example adapters 302, 308, 316, 320 configured with different connector types. In FIGS. 3A-3E, the different types of connectors are attached to the ends of the support tube 144. The example adapter 142A of the example stroller 100 of FIG. 1 can support different types of accessories and/or seats to be mounted to the stroller 100 that are compatible with the different types of connectors. While several example connector types are disclosed herein, such examples do not limit the generality of the mounting capabilities of the adapter 142 A.
[0037] The example adapter 142A of the illustrated example of FIG.
3A has the first and second connectors 146A, 148A of a first type attached to the support tube 144 to couple a car seat or other accessory type. Similarly, the example adapter 302 of the illustrated example of FIG. 3B has first and second connectors 304, 306 of a second type attached to the support tube 144 to couple a car seat or other accessory type. In the examples of FIGS. 3 A and 3B, an accessory or seat is coupled to the upright support tube 144 of the respective adapter 142A, 302. In some examples, the connection is a bayonet- style connection. The different connectors 146A, 148A, 146B, 148B, 304, 306 may be used to removably couple accessories of different configurations and/or accessories from different manufacturers to the stroller.
[0038] The example adapter 308 of the illustrated example of FIG. 3C has first and second connectors 310, 312 of a third type attached to the support tube 144 to couple a car seat or other accessory type. Similarly, the example adapter 316 of FIG. 3D and the example adapter 320 of FIG. 3E also include the first and second connectors 310, 312 of the third type to couple a car seat or other accessory to the stroller. In FIG. 3C, the first connector 310 and the second connector 312 are coupled to a bar 314 of a first configuration to which an accessory, such as for example, the car seat, is removably coupled. In FIG. 3D, the first connector 310 and the second connector 312 are coupled to a bar 318 of a second configuration to which an accessory, such as for example, the car seat, is removably coupled. In FIG. 3E, the first connector 310 and the second connector 312 are coupled to a bar 322 of a third configuration to which an accessory, such as for example, the car seat, is removably coupled. The different configurations of the first bar 314, the second bar 318, and the third bar 322 may be used to removably couple accessories of different configurations and/or accessories from different manufacturers to the stroller.
[0039] FIG. 4 is a perspective view from the front and left side of the adapter 142 A of the example stroller 100 of FIG. 1. While reference is made to the adapter 142A, all description in association with FIG. 4, as well as all other figures depicting the adapter 142 A, additionally applies to the adapter 142B, and the adapters 302, 308, 316, and 320. The example adapter 142A includes the first connector 146A and the second connector 148A removably coupled to the support tube 144 via example connector fasteners 402. In some examples, connector fasteners 402 are snap-on connectors. In some other examples, the connector fasteners 402 are latch mechanisms. In yet other examples, the connector fasteners 402 are any suitable material and/or mechanism and/or combination of materials and/or mechanisms to mount or releasably couple the first connector 146A and the second connector 148 A to the support tube 144.
[0040] The example adapter body 150 includes an example upper housing 404 and an example lower housing 406. The upper housing 404 includes an opening for an example lateral adjustment button 408 to protrude through the upper housing 404. The lateral adjustment button 408, when depressed, enables the support tube 144 to translate through the adapter body 150. The lower housing 406 includes openings for an example latch 410 and an example latch release 412. The latch 410 engages one of the receptacles 140 on the mounting support member 136 of the example stroller 100 of FIG.
1 to removably couple the adapter 142A to the stroller 100. The latch 410 is located at an upper portion of an example end portion 414 of the adapter body 150. The end portion 414 is received by one of the receptacles 140 on the mounting support member 136 during mounting of the adapter 142A. The end portion 414 has a frustoconical geometry that enables the end portion 414 and the adapter 142A to be easily mounted and received by one of the receptacles 140 of the stroller 100. The end portion 414 further includes an example lip 416 that matches or complements a corresponding cavity in one of the receptacles 140 of the stroller 100 of FIG. 1. Further detail of the structure, function, and operation of the end portion 414, the latch 410, and the receptacles 140 of the stroller 100 of FIG. 1 is disclosed in FIGS. 6A-6B.
[0041] FIG. 5 is a top view of the mounting support member 136 of the example stroller 100 of FIG. 1 without any of the adapters 142 A, 142B, 302, 308, 316, 320 mounted to the receptacles 140 of the mounting support member 136. The example mounting support member 136 includes three receptacles 140. The receptacles 140 are evenly spaced along the mounting support member 136. In some examples, the mounting support member 136 can include fewer or more receptacles 140, at any spacing along the mounting support member 136. The receptacles 140 have geometry corresponding to geometry of the end portion 414 of the adapter 142A to enable coupling of the adapter 142A to the mounting support member 136.
[0042] The receptacles 140 include two latch slots 502 respectively and two alignment ledges 504 respectively, positioned under the latch slots 502. When a user inserts the adapter 142A into one of the receptacles 140, the user places the end portion 414 of the adapter 142A into one of the receptacles 140, causing the latches 410 to retract until the latches 410 are aligned with the latch slots 502. The alignment ledges 504 are substantially perpendicular ledges directly below the latch slots 502 that are shaped to conform to the lip 416 of the end portion 414 of the adapter 142A. As the receptacles 140 and the adapter 142A have a generally frustoconical shape, a user can rotate the adapter 142A during insertion until the latches 410 engage the latch slots 502. The receptacles 140 also have a relatively long side (e.g., perpendicular to the direction of the length of the mounting support member 136) and a relatively short side (e.g., in the direction of the length of the mounting support member 136), enabling the user to orient the adapter 142A into a position to facilitate alignment of the latch 410 and to simplify mounting of the adapter 142 A.
[0043] FIG. 6A is a cross-sectional view of the example adapter body 150 of the adapter 142A taken along the 6-6 line of FIG. 4. The adapter body 150 includes features to couple the adapter 142A to the stroller 100, as well as lateral adjustment features to enable the support tube 144 to translate between multiple lateral positions. [0044] At the end portion 414 of the adapter 142A, the lower housing 406 has an example cavity 602 including example support material 604, to provide the lower housing 406 with rigidity. In some examples, the lower housing 406 includes more or less support material (e.g., a smaller cavity, no cavity, a larger cavity, etc.), depending on structural parameters (e.g., desired rigidity, ability to house other structural components that extend into the end portion 414, etc.). The outer walls of the end portion 414 are contoured to be substantially flush with surfaces of one of the receptacles 140 when the adapter 142 A is mounted in one of the receptacles 140. Additional outer surfaces of the lower housing 406 have outer surfaces with a slope or curvature at least partially complementing the slope or curvature of surfaces of the receptacles 140 of FIGS. 1 and 5. A cross-sectional view of the adapter mounted in one of the receptacles of the mounting support member is depicted in FIG. 6B.
[0045] The lower housing 406 additionally includes an example central support wall 606 including latch spring retention features 608. The central support wall 606 extends from a top surface of the cavity 602 upwards and is disposed below an example retainer 609. The latch spring retention features 608 of the example central support wall 606 are two cylindrical extrusions extending perpendicularly off of the central support wall 606 and enclosed by the diameter of the respective latch springs 610. The latch spring retention features 608 retain the latch springs 610 in a position such that force applied to the latches 410 (e.g., via the latch release 412, or via a vertical force to the diagonal external latch surface when being placed in a receptacle 140, etc.) is transferred to the latch spring 610, resulting in a corresponding displacement to retract the latches 410 into the adapter 142A. The internal surfaces of the latches 410 additionally have latch spring retention features 608 including cylindrical extrusions extending from an internal surface of the latch 410. The latch spring retention features 608 are thereby able to maintain the position of the latch springs 610 and enable any load applied to the latches 410 to be transferred to the latch springs 610.
[0046] In the example adapter 142A, the latch 410 and the latch release 412 are one continuous part (e.g., the latch 410 and the latch release 412 are integral). In other examples, the latch 410 and the latch release 412 are separate parts. Also, in the illustrated example, the latches 410 and latch releases 412 are substantially the same on each side of the adapter 142A. In addition, in some examples, the latch 410 and the latch release 412 engage the latch springs 610 at different locations and/or via different mechanisms (e.g., via additional intervening parts).
[0047] The retainer 609 of the example adapter 142A is centrally positioned in the adapter 142A. The retainer 609 provides a plurality of alignment surfaces. For example, the retainer 609 includes an example central cylindrical cavity 612 wherein an end of an adjustment pin 614 is slidably disposed and an example pin spring 616 is housed. The adjustment pin 614, when depressed due to a force applied to the lateral adjustment button 408, translates further into the central cylindrical cavity 612 of the retainer 609 in opposition to the force of the pin spring 616. When fully depressed, and the adjustment pin 614 is in a retracted position, an example nominal diameter portion 617 of the adjustment pin 614 contacts a bottom surface of the central cylindrical cavity 612 of the retainer 609. In some examples, when the adjustment pin 614 is fully depressed, an example flange surface 632 of the lateral adjustment button 408 may contact the support tube 144 or contact example support tube brackets 628 disposed on top of the support tube 144. Conversely, when the adjustment pin 614 is in an extended position, corresponding to the lateral adjustment button 408 extending maximally out of the opening in the upper housing 404, an example flange surface 632 of the lateral adjustment button 408 interferes with an example upper surface 634 of the upper housing 404 to retain the lateral adjustment button 408 and the adjustment pin 614.
[0048] The adjustment pin 614 includes four reduced diameter portions. The first reduced diameter portion 618 and the second reduced diameter portion 620 interfere with respective example upper and lower slots 802, 804 (e.g., as depicted in FIG. 8A) of the support tube 144, when the adjustment pin 614 is in the extended position. As shown in FIGS. 8A-B, the upper slot 802 and the lower slot 804 are geometrically similar slots on respective upper and lower surfaces of the support tube 144. By interfering with the support tube 144, the upper slot 802 and the lower slot 804 lock the support tube 144 into a position. The support tube 144 includes one or more example lateral positions 702, 704, 806 (e.g., cut-out portions) at positions along the upper and lower slots 802, 804, with diameters larger than the nominal diameter portion 617 of the of the adjustment pin 614. The first and second lateral positions 702, 704 are depicted in FIG. 7, and the third lateral position 806 is depicted in FIG. 8B. To move the support tube 144 between these lateral portions 702, 704, 806 (e.g., circular portions), a user can apply a force to the lateral adjustment button 408 to depress the adjustment pin 614 to a retracted position wherein the first reduced diameter portion 618 and the second reduced diameter portion 620 of the adjustment pin 614 are respectively aligned with the upper slot 802 and the lower slot 804 of the support tube 144. The first reduced diameter portion 618 and the second reduced diameter portions 620 have diameters that are respectively smaller than the width dimensions of the upper slot 802 and the lower slot 804 (e.g., the width dimension being the shortest distance across a gap of one of the slots, corresponding to the direction perpendicular to the length of the slots). Once a user has applied a force to the lateral adjustment button 408 to align the first and second reduced diameter portions 618, 620 with the respective upper slot 802 and lower slot 804 of the support tube 144, and additionally applied a lateral force to the support tube 144 (e.g., in the same direction as the length of the upper slot 802 and the lower slot 804), the adjustment pin 614 will remain in a retracted position until another one of the lateral positions 702, 704, 806 of the upper and lower slots 802, 804 is aligned with the adjustment pin 614. Therefore, once the support tube 144 has translated away from a lateral position, the adjustment pin 614 can remain in the retracted position even after a force is no longer applied to the lateral adjustment button 408, due to interference between the adjustment pin 614 and surfaces of the upper and lower slots 802, 804. Absent a force from the user on the lateral adjustment button 408, once the support tube 144 has been translated to one of the first, second or third lateral positions 702, 704, 806 (e.g., circular portions) of the upper and lower slots 802, 804, the adjustment pin 614 will return to the extended position due to the force of the pin spring 616 and lack of interference.
[0049] The example adjustment pin 614 additionally includes an example third reduced diameter portion 622 and an example fourth reduced diameter portion 624. The third reduced diameter portion 622 is sized to engage an adjustment pin clip 626. The adjustment pin clip 626 has a diameter that is smaller than the nominal diameter of the adjustment pin 614, but larger than the diameter of the fourth reduced diameter portion 624. The adjustment pin clip 626, by being disposed around the fourth reduced diameter portion 624, acts as a flange extension of the adjustment pin 614, giving the coupled combination (e.g., the adjustment pin 614 and the adjustment pin clip 626) a larger local diameter and enabling the force applied to the adjustment pin 614 to be transferred to the pin spring 616. Absent the adjustment pin clip 626, the adjustment pin 614 would not be in direct contact with the pin spring 616. In some examples, the adjustment pin 626 itself can be otherwise coupled to the pin spring 616 via a different mechanism (e.g., direct coupling of the pin spring 616 to a slot in the adjustment pin 626, an increased diameter flange of the adjustment pin 614 itself, etc.). The example fourth reduced diameter portion 624 enables the adjustment pin 614 to translate through the central cylindrical cavity 612 of the retainer 609. In some examples, the fourth reduced diameter portion 624 enables the adjustment pin 614 to maintain alignment within the central cylindrical cavity, restricting the adjustment pin 614 to translating between the extended position and the retracted position.
[0050] The support tube 144 of the example adapter 142 A is coupled to the two support tube brackets 628 that are disposed on top of the support tube 144 and within the enclosure of the upper housing 404 and the lower housing 406. The support tube brackets 628 include respective alignment flanges 630 that are disposed between surfaces of the upper housing 404 to enable alignment of the support tube 144 within the adapter 142 A. In some examples, the alignment flanges 630 come into contact with the upper housing 404 if a force is applied to the external top surface of the upper housing 404.
In such examples, the support tube bracket 628 can provide structural support to the upper housing 404 by receiving force applied to the upper housing 404 and reducing deflection of the upper housing 404. The support tube brackets 628 extend only partially in the direction into the page (e.g., the direction of the length of the support tube within the adapter 142A), such that when the support tube 144 is translated between lateral positions, the support tube brackets 628 do not interfere with surfaces of the upper housing 404.
[0051] FIG. 6B is a cross-sectional view of the example adapter body 150 of the example adapter 142A of FIGS. 4 and 6A when mounted in one of the receptacles 140 of the mounting support member 136 of the example stroller 100 of FIG. 1. When the adapter 142 A is fully mounted in the receptacle 140, the latches 410 are disposed within the latch slots 502, such that top surfaces of each of the latches 410 are directly under top surfaces of the latch slots 502, preventing removal of the adapter 142A from the receptacle 140 until the latches 410 are retracted. Additionally, when the adapter 142A is fully mounted in the receptacle 140, the lips 416 of the adapter 142 A are aligned substantially flush with bottom and side surfaces of the alignment ledges 504 of the receptacle 140. To remove the adapter 142 A from the receptacle 140, the user would have to apply a force to the latch releases 412 sufficient to eliminate any interference between the latches 410 and the latch slots 502. In the example adapter 142A, the user can compress the latch releases 412 (e.g., apply forces on each of the latch releases 412 toward the center of the adapter 142 A, in opposition to the latch springs 610) and lift the adapter 142A away from the receptacle 140 to remove the adapter 142 A from the mounted position.
[0052] FIG. 7 is a cross-sectional view of the adapter body 150 of the adapter 142 A taken along the 7-7 line of FIG. 4. The example support tube 144 of the adapter 142A is in a central position in FIG. 7, with the support tube 144 locked in position. In the locked position, the support tube 144 is unable to translate to another lateral position without a force being applied to the lateral adjustment button 408. When a force is applied to the lateral adjustment button 408, the adjustment pin 614 is depressed in opposition to the pin spring 616 disposed within the retainer 609. When the adjustment pin 614 is depressed the first reduced diameter portion 618 is aligned with the upper slot 802 and the second reduced diameter portion 620 is aligned with lower slot 804, and the support tube 144 can be translated between three lateral positions: a first lateral position 702 (e.g., the“left” position), a second lateral position 704 (e.g., the“right” position), and a third lateral position 806 (e.g., the“center” position, as depicted in FIG. 8B). In the cross-sectional view of FIG. 7, the support tube 144 is locked into the third lateral position 806, resulting in the adjustment pin 614 filling the upper and lower slots 802, 804 at the third lateral position 806. The first lateral position 702, the second lateral position 704, and the third lateral position 806 are areas of the upper and lower slots 802, 804 of the support tube 144 that have a larger diameter circular portion for the adjustment pin 614 to be disposed within.
[0053] In some examples, the upper slot 802 and lower slot 804 can include additional lateral positions to support additional discrete adjustment positions. Combined with the capability for the adapter 142A to be mounted in any one of the receptacles 140, the numerous lateral positions on the upper and lower slots 802, 804 of the support tube 144 enable a large variety of seat and/or accessory mounting configurations.
[0054] FIG. 7 also illustrates one of the two support tube brackets 628 that are attached to the support tube 144. The length of the support tube bracket 628 is limited to enable the support tube 144 to translate between the first lateral position 702, the second lateral position 704, and the third lateral position 806 without the support tube brackets 628 interfering with the upper housing 404. Thus, the support tube 144 can be laterally adjusted without moving, e.g., laterally moving, the upper housing 404 and the adapter body 150 overall.
[0055] The example end portion 414 of the lower housing 406 has a narrower width at the bottom of the end cavity 602, as shown in FIG. 7, than the length of the end portion 414, as shown in FIG. 6A. This elongated shape enables a user to easily determine a general orientation for mounting the adapter 142 A into one of the receptacles 140 and simplifies alignment of the latches 410 with the latch slots 502, as depicted in FIG. 6B.
[0056] FIG. 8A is a perspective cross-sectional view of the example adapter body 150 of FIG. 7, with the upper housing 404 and the lower housing 406 removed. In this view, the example first lateral position 702 and second lateral position 704 on the support tube 144 are clearly visible. The first lateral position 702, the second lateral position 704, and the third lateral position 806 (e.g., as visible when the support tube is in transition between lateral positions as in FIG. 8B) exist on both the upper slot 802 and lower slot 804 of the support tube 144 to enable the adjustment pin 614 to be disposed in these positions, thereby locking (e.g., preventing translation of) the support tube 144.
[0057] FIG. 8B is the perspective view of FIG. 8A, but with the adjustment pin 614 depressed and the support tube 144 in transition between the first and third lateral positions 702, 806. When the adjustment pin 614 is depressed (e.g., due to a force applied on the lateral adjustment button 408), the first reduced diameter portion 618 is aligned with the upper slot 802, and the second reduced diameter portion 620 is aligned with the lower slot 804, enabling translation of the support tube 144 in the lateral direction.
[0058] FIG. 9 is an exploded view of the example adapter 302 of FIG. 3B. While the adapter 302 includes the first and second connectors 304, 306, the remaining structure of the adapter 302 is the same as the adapters 142 A, 142B, 308, 316, 320. Hence, while the example adapter 302 is depicted in FIG. 9, this depiction, as well as all associated description, applies equally to the adapters 142A, 142B, 308, 316, 320. As shown in FIG. 9, the adapter 302 includes the upper housing 404. When assembled, the lateral adjustment button 408 is positioned in a hole 902 in the upper housing 404, with a portion of the lateral adjustment button 408 protruding above the upper surface 634 of the upper housing 404 and the flange surface 632 remaining under the upper housing 404 to retain the lateral adjustment button 408 within the adapter body 150. The lateral adjustment button 408 is positioned directly above the adjustment pin 614. The adjustment pin 614 is positioned within both upper and lower slots 802, 804 of the support tube 144 and between the support tube brackets 628. The support tube brackets 628 are coupled to the support tube 144 via two fasteners assembled along the length of each of the support tube brackets 628. In some examples, the support tube brackets 628 can be coupled to the support tube 144 via any suitable mechanical and/or chemical fastener or combination of fasteners (e.g., rivets, screws, adhesive, etc.) and/or may be part of the support tube 144 (e.g., as a unitary or integral piece).
[0059] At the bottom of the adjustment pin 614 are the adjustment pin clip 626 and the pin spring 616, which are disposed within a central cavity of the retainer 609. When assembled, the adjustment pin clip 626 is disposed within a reduced diameter portion of the adjustment pin 614, below the support tube 144. The adjustment pin clip 626 is coupled to the adjustment pin 614 such that a movement of the adjustment pin 614 results in a corresponding movement in the adjustment pin clip 626. The adjustment pin clip 626 has a surface area that extends beyond the outer diameter of the pin spring 616, thus exerting a force on the pin spring 616 when the adjustment pin 614 is displaced further into the central cavity of the retainer 609.
[0060] In addition to housing the pin spring 616, the retainer 609 additionally includes latch spring retention features on the bottom side of the retainer 609 for mounting of the latch springs 610. Each of the latch springs 610 additionally directly engages with respectively latches 410. In the example adapter 302, the latches 410 are attached to the latch releases 412, such that a force applied to the latch releases 412 results directly in a corresponding force on the latch springs 610. In this example, the retainer 609 is directly coupled to the lower housing 406 via four fasteners at comers of the retainer 609. In some examples, other suitable mechanical and/or chemical fasteners or combination of fasteners may be utilized to couple the retainer 609 directly or indirectly to the lower housing 406.
[0061] The lower housing 406 is coupled to the upper housing 404 via fasteners that are placed through the lower housing 406 and extend to the upper housing 404 to enclose the components of the adapter 302. In some examples, the lower housing 406 and the upper housing 404 may be coupled via snap-fit connectors or any other suitable mechanical and/or chemical fasteners or combination of fasteners. The latches 410 as well as the latch releases 412 are positioned in the lower housing 406 such that external surfaces of the latches 410 and latch releases 412 extend out of the lower housing 406 through openings 904 in the lower housing 406.
[0062] FIG. 10 is a flow chart illustrating an example process 1000 for removably coupling an adapter (e.g., the adapter 142A) to a foldable frame (e.g., via the mounting support member 136) of a stroller (e.g., the example stroller 100). Although the example process 1000 is disclosed with respect to the flowchart illustrated in FIG. 10, many other methods of operating the example adapter 142A may alternatively be used. For example, the order of execution of the blocks may be changed, and/or some of the blocks described may be changed, eliminated, or combined.
[0063] The example process 1000 of FIG. 10 includes removably coupling the adapter to an open receptacle (block 1002). For example, a user can insert the end portion 414 of the adapter 142 A into one of the receptacles 140. The user can align the end portion 414 such the geometry of the end portion 414 matches or corresponds to the geometry of the receptacle 140 (e.g., aligning the length of the end portion 414 with the length of the receptacle 140). After placing the adapter 142A into the receptacle 140, the user can apply a coupling force to the adapter 142A (e.g., push the adapter 142 A downward toward the ground) until the latches 410 engage the latch slots 502.
[0064] The example process 1000 also includes determining whether to change a connector type on the adapter (block 1004). For example, the user can decide whether the first connector 146A and the second connector 148A of the adapter 142A should be changed. In some examples, the user may change the first connector 146A and/or the second connector 148A to another desired or suitable connector (e.g., first and second connectors 146 A, 148A, 146B, 148B, 304, 306, 310, 312). In some examples, the user can utilize the same connector type for both the first connector 146A and the second connector 148 A, depending on the connector type required by the accessory/seat. In response to the user deciding that the connector type on the adapter 142A should be changed, the process 1000 continues and the user decouples the connectors from the adapter (block 1006). Conversely, if the user decides that the connector type on the adapter 142 A should not be changed (block 1004), the example process 1000 continues with the user determining if a lateral position of a support tube is to be adjusted (block 1010).
[0065] Where the user decides to change a connector type (block 1004), the user decouples the current connector(s) from the adapter (block 1006) in order to change the connector type on the adapter. For example, the user can loosen, remove, or otherwise deactivate fasteners (e.g., the connector fasteners 402 of FIG. 4) to remove the first connector 146A and/or the second connector 148 A from the support tube 144. Once removed, the user can removably couple desired connector(s) to the adapter (block 1008). For example, the user can couple any of the example connectors (e.g., first and second connectors 146A, 148A, 146B, 148B, 304, 306, 310, 312) as a first connector and/or second connector on the support tube 144. The user can use any method of coupling (e.g., a fastener, snap-fit, etc.) to removably couple the desired connectors to the adapter 142 A.
[0066] The example process 1000 also includes the decision of whether to adjust the lateral position of the support tube (block 1010). For example, the user can decide to move the support tube 144 to a left position, a center position, or a right position. In some examples, the user can decide to move the support tube 144 to one of the positions in order to accommodate an additional adapter 142A including an additional seat and/or accessory. In response to the user deciding to adjust the lateral position of the support tube 144 (block 1010), the example process 1000 includes retraction of the adjustment pin using the lateral adjustment button to start the lateral adjustment (block 1012). Conversely, in response to the user deciding not to adjust the lateral position of the support tube 144 (block 1010), the example process 1000 includes attachment of a seat or accessory to the adapter 142A via the first and second connectors 146A, 148A (block 1018).
[0067] When the user decides to adjust the lateral position of the support tube (block 1010), the example process 1000 includes retracting the adjustment pin using the lateral adjustment button (block 1012). For example, the user can retract the adjustment pin 614 by applying a downward force (e.g., toward the ground) to the lateral adjustment button 408. While maintaining this force (e.g., maintaining the adjustment pin 614 in the retracted position), the user can translate the support tube to the desired position (block 1014). For example, the user can apply a lateral force to the support tube 144 to move the support tube 144 (and consequently, the first connector 146 A and the second connector 148 A) between different lateral positions. The user can move the support tube 144 until the adjustment pin 614 is engaged with one of the three alignment positions (e.g., a left position, a center position, a right position). In some examples, once the support tube 144 has been translated out of one of the lateral positions, the adjustment pin 614 may remain in the retracted state until the support tube 144 is translated to one of the lateral positions, due to interference between the adjustment pin 614 and the upper and lower slots 802, 804 of the support tube 144. In such examples, the user may not be required to continually apply force to the adjustment button 408, but can rather apply the initial force to the adjustment button 408, translate the support tube 144 out of the original position, release the adjustment button 408, and continue to translate the support tube 144 to the desired lateral position. Once the support tube 144 is positioned in one of the lateral positions, the adjustment pin 614 should be able to fully retract.
Alternatively, the user can release the lateral adjustment button 408 (block 1016) once the desired lateral position is reached.
[0068] The example process 1000 also includes attaching a seat and/or accessory to the adapter via the connectors (block 1018). For example, a car seat or an accessory (e.g., a basket, a bassinet, etc.) can be attached to the adapter 142 A using the first and second connectors 146A, 148 A. In some examples, the user can align the seat or accessory with the first and second connectors 146A, 148A, and mount the seat or accessory to the support tube 144 by applying pressure to the seat and/or accessory until the seat and/or accessory is locked into a mounted position on the first and second connectors 146 A, 148 A.
[0069] Following the attachment of the seat or accessory to the adapter 142A, the user determines whether or not to attach another seat or accessory to the stroller (block 1020). In response to the user deciding to attach another seat or accessory to the stroller, the example process 1000 returns to block 1002 with the user removably coupling a second adapter to a second open receptacle. Conversely, in response to the user deciding not to attach another seat or accessory to the stroller (block 1020), the example process 1000 for assembly and adjustment of the stroller terminates.
