Travel system having a child carrier and travel organizer that couples thereto

Abstract

In one example, a organizer is removably coupled to a handle of a child vehicle. The organizer has a bracket, a storage container, and a flexible material. The bracket has an opening extending from its lower end to its upper end and can accommodate an item for storage. The storage container is positioned below the bracket and has an open upper end and a closed lower end. The flexible material is coupled to the bracket and the storage container. The organizer transitions between an extended configuration and a compact configuration, in which the flexible material defines the organizer on the side between the bracket and the storage container, and in the compact configuration, the bracket and the storage container are positioned closer to each other. In another example, the child vehicle has a handle that extends and retracts, and when the handle is extended, it prevents the organizer from being installed.

Description

Technical Field

[0001] This disclosure is primarily about wheeled strollers used for carrying children. Prior Technology

[0002] Strollers are commonly used to transport toddlers, such as when carrying an infant in a car seat after removing it from a vehicle. Most strollers include a foldable frame that allows them to be stored in the trunk of a car or other storage locations. Reducing the folded size of strollers has been a goal of the children's products industry for some time. Although improvements have been made in this area, the industry still hopes to reduce the folded size of strollers. Summary of the Invention

[0003] In one example, a system includes a child carrier and a travel organizer. The child carrier includes a handle to be gripped by a caregiver, the handle having a first side bar and a second side bar spaced apart from each other to define a space therebetween. The travel organizer is configured to attach to the handle in the space between the first and second side bars. The travel organizer includes a bracket having an upper bracket end and a lower bracket end spaced vertically from the upper bracket end. The bracket defines at least one bracket opening extending toward the lower bracket end into the upper bracket end, wherein the at least one bracket opening is configured to store items. The travel organizer has a storage container disposed below the bracket. The storage container has a container upper end and a container lower end spaced vertically from the container upper end. The container upper end defines at least one container opening extending into the container upper end and terminating before the container lower end, such that the bottom of the at least one container opening is closed. The travel organizer includes a flexible material having an upper end and a lower end offset from each other in a vertical direction. A flexible material defines a storage space extending between the upper and lower ends. The upper end is coupled to a bracket, and the lower end is coupled to a storage container. The travel organizer is configured to switch between an unfolded configuration and a compact configuration. In the unfolded configuration, the bracket and storage container are offset from each other by a first distance, and the flexible material defines the organizer's side between the bracket and the storage container. In the compact configuration, the bracket and storage container are offset from each other by a second distance less than the first distance.

[0004] In another example, a system includes a child carrier and a organizer. The child carrier includes a handle to be gripped by a caregiver. The handle has a first side bar and a second side bar, spaced apart from each other to define a space therebetween. The handle has a gripping bar extending between the first and second side bars. The handle is configured to switch between a retracted position and an extended position. The organizer is configured to be removably coupled to the handle between the first and second side bars. The organizer has an upper end and a lower end spaced vertically from the upper end. The organizer defines at least one opening extending toward the lower end to the upper end, wherein at least one opening is configured to receive an item therein. The child carrier is configured such that the organizer can only be installed when the handle is in the extended position. Simple Explanation of the Diagram

[0070] [Cross-reference to related applications] This application claims priority to U.S. Provisional Patent Application No. 63 / 128,441, filed December 21, 2020; U.S. Provisional Patent Application No. 63 / 174,843, filed April 14, 2021; and U.S. Provisional Patent Application No. 63 / 237,443, filed August 26, 2021, the disclosures of all of the above U.S. Provisional Patent Applications of which are hereby incorporated herein by reference as if their entire contents were set forth herein.

[0071] Referring to Figures 1 and 2, a travel system 10 is shown according to an example, comprising a stroller 100 and at least one removable child carrier. Generally, at least one removable child carrier may comprise an infant car seat 200 as shown in Figures 1 and 2, a toddler seat 400 as shown in Figure 36A, a cradle (not shown), or a portable crib (not shown). In some examples, the travel system 10 may comprise an infant car seat 200, a toddler seat 400, a cradle, or a portable crib, or any combination thereof. The stroller 100 includes: a frame 102 configured to support the child carrier (e.g., 200, 400) above a travel surface; and a plurality of wheels 104 attached to the frame 102 and configured to allow the stroller 100 and the child carrier (e.g., 200, 400) to translate along the travel surface. The child carrier (e.g., 200, 400) and the stroller 100 are configured to be removably coupled to each other. When not in use, the stroller 100 can be compactly folded for storage in a vehicle, aircraft overhead storage compartment, or other storage location. As will be discussed in further detail below, the stroller 100 can be configured to fold from an unfolded configuration to a first folded configuration (e.g., Figures 8A to 8C), and may be configured, depending on the situation, to fold from the first folded configuration to a second folded configuration (e.g., Figures 9A, 9B), wherein the stroller 100 occupies a smaller volume in the second folded configuration compared to the first folded configuration.

[0072] Unlike conventional strollers, stroller 100 does not have a push handle for pushing a child. In other words, stroller 100 does not have a handle extending above the child carrier that an adult could reach to push the stroller 100 while upright. More precisely, the child carrier (e.g., 200, 400) includes a handle (e.g., 226 in Figure 10, 404 in Figure 36A) that a caregiver can use to push the stroller 100 and the child carrier (e.g., 200, 400) along the travel surface when the child carrier (e.g., 200, 400) is coupled to stroller 100. In some instances, the same handle (e.g., 226) can be used to carry the child carrier (e.g., 200) when it is detached from stroller 100. The child carrier (e.g., 200, 400) is configured such that removing the child carrier (e.g., 200, 400) from the stroller 100 will cause the handle (e.g., 226, 404) to be removed from the stroller 100 along with the child carrier (e.g., 200, 400). Therefore, the stroller 100 achieves a more compact folding volume compared to comparable conventional strollers that include a push handle. In some instances, the travel system 10 may include a travel organizer 300, which may be configured to hold at least one item such as a beverage container, mobility device, or other caregiver items. The travel organizer 300 may be configured to be removably coupled to the handle (e.g., 226, 404) of the child carrier (e.g., 200, 400).

[0073] [Stroller]

[0074] Turning more specifically to Figures 2 to 4, the frame 102 of the stroller 100 includes an upper end 102a and a lower end 102b offset from each other along a vertical direction V. The frame 102 includes a front end 102c and a rear end 102d offset from each other along a longitudinal direction L perpendicular to the vertical direction V. The frame includes a first side 102e and a second side 102f offset from each other along a lateral direction A perpendicular to both the vertical direction V and the longitudinal direction L.

[0075] The stroller 100 includes a plurality of wheels 104 disposed at the lower end 102b of a frame 102. The upper end 102a of the frame 102 is configured to be removably coupled to a child carrier (e.g., 200, 400) such that the child carrier (e.g., 200, 400) is spaced apart above a travel surface. As will be described in further detail below, the upper end 102a of the frame 102 includes at least one seat coupler configured to removably couple a child carrier (e.g., 200, 400) to the stroller 100 such that movement of the child carrier (e.g., 200, 400) relative to the stroller 100 is restricted in at least one of the vertical direction V, the longitudinal direction L, and the lateral direction A. In some instances, at least one seat coupler is configured to removably couple a child carrier (e.g., 200, 400) to a stroller 100 such that movement of the child carrier (e.g., 200, 400) relative to the stroller 100 is restricted in at least two of the vertical direction V, the longitudinal direction L, and the lateral direction A, such as all three of the vertical direction V, the longitudinal direction L, and the lateral direction A. For example, at least one seat coupler may be configured to removably couple a child carrier (e.g., 200, 400) to the stroller 100 to prevent the child carrier (e.g., 200, 400) from being removed in an upward direction. At least one seat coupler may be configured to be removably coupled to a rigid part of a child vehicle (e.g., 200, 400), such as the rigid body (e.g., 202 in FIG. 10) or housing of the child vehicle (e.g., 200) or the rigid frame of the child vehicle (e.g., 400) (e.g., 402 in FIG. 36A).

[0076] Frame 102 may include a first leg assembly 106(1) and a second leg assembly 106(2) offset from each other along a lateral direction A. The first leg assembly 106(1) may be adjacent to a first side 102e, and the second leg assembly 106(2) may be adjacent to a second side 102f. The first leg assembly 106(1) may include a first front leg 108(1) and a first rear leg 110(1) offset from each other along a longitudinal direction L perpendicular to the lateral direction A. The first leg assembly 106(1) may include a first hinge 112(1) that pivotally connects the first front leg 108(1) and the first rear leg 110(1) to each other. For example, the first hinge 112(1) may pivotally couple the upper end of the first front leg 108(1) to the upper end of the first rear leg 110(1). The first hinge 112(1) may define a pivot axis AP1 extending along the lateral direction A. The first front support leg 108(1) and the first rear support leg 110(1) can be configured to pivot about the pivot axis AP1 such that the lower ends of the first front support leg 108(1) and the lower ends of the first rear support leg 110(1) move toward each other along the longitudinal direction L to a first folded configuration, and move away from each other along the longitudinal direction L to an unfolded configuration.

[0077] The second leg assembly 106(2) may include a second front leg 108(2) and a second rear leg 110(2) offset from each other along the longitudinal direction L. The second leg assembly 106(2) may include a second hinge 112(2) that pivotally connects the second front leg 108(2) and the second rear leg 110(2) to each other. For example, the second hinge 112(2) may pivotally couple the upper end of the second front leg 108(2) to the upper end of the second rear leg 110(2). The second hinge 112(2) may define a pivot axis AP1 extending along the lateral direction A. The second front leg 108(2) and the second rear leg 110(2) may be configured to pivot about the pivot axis AP1 such that the lower ends of the second front leg 108(2) and the lower ends of the second rear leg 110(2) move toward each other along the longitudinal direction L to a first folded configuration and move away from each other along the longitudinal direction L to an unfolded configuration.

[0078] Frame 102 may include at least one crossbar 114(1), 114(2) extending between a first leg assembly 106(1) and a second leg assembly 106(2) such that the first leg assembly 106(1) and the second leg assembly 106(2) are spaced apart from each other in a lateral direction A. Each crossbar may be shaped as a rod, a tube, or may have any other suitable shape. At least one crossbar 114(1), 114(2) may include a first crossbar 114(1) extending from a front leg 108(1) to a front leg 108(2). The first crossbar 114(1) may have a first end attached to a first front leg 108(1) and a second end attached to a second front leg 108(2). At least one crossbar 114(1), 114(2) may include a second crossbar 114(2) extending from a first rear leg 110(1) to a second rear leg 110(2). The second crossbar 114(2) may have a first end attached to the first rear support leg 110(1) and a second end attached to the second rear support leg 110(2). In some embodiments, the frame 102 may include a third crossbar 114(3) extending between the first support leg assembly 106(1) and the second support leg assembly 106(2). The third crossbar 114(2) may be positioned above the first crossbar 114(1) and the second crossbar 114(2) relative to the vertical direction V. When the stroller 100 is in an unfolded configuration, the third crossbar 114(2) may be positioned between the first crossbar 114(1) and the second crossbar 114(2) relative to the longitudinal direction L. The third crossbar 114(3) may define a handle 122. The handle 122 may be configured for carrying the stroller 100 by hand when the child carrier (e.g., 200, 400) is detached from the stroller 100.

[0079] The plurality of wheels 104 may include at least three wheels 104, and in some instances, may include four wheels 104. For example, the plurality of wheels 104 may include a first pair of wheels 104 located at the rear end 102d of the frame 102. The first wheel 104 of the first pair may be coupled to the lower end of the first rear support leg 110(1) of the first support leg assembly 106(1), and the second wheel 104 of the first pair may be coupled to the lower end of the second rear support leg 110(2) of the second support leg assembly 106(2). The plurality of wheels 104 may include at least one wheel 104 located at the front end 102e of the frame 102. For example, the plurality of wheels 104 may include a second pair of wheels 104 located at the front end 102e of the frame 102. The first wheel 104 of the second pair may be coupled to the lower end of the first front support leg 108(1) of the first support leg assembly 106(1), and the second wheel 104 of the second pair may be coupled to the lower end of the second front support leg 108(2) of the second support leg assembly 106(2). Alternatively, the plurality of wheels may include a single wheel 104 (not shown) located at the front end 102e of the frame. The single wheel 104 may be coupled to the lower end of the frame 102 at a position between the front support leg 108(1) and the front support leg 108(2), or the frame 102 may include a single front support leg to which the wheel 104 is attached.

[0080] As discussed above, stroller 100 may include at least one coupler configured to couple a child carrier (e.g., 200, 400) to stroller 100. Figures 2 to 4 show a particular example of a coupler that can be used to couple a child carrier (e.g., 200, 400) to stroller 100; however, it should be understood that a child carrier (e.g., 200, 400) may be coupled to stroller 100 using another or more suitable couplers. In some instances, as shown in Figures 2 to 4, at least one coupler may include a first pair of couplers 116(1), 116(2). The first coupler 116(1) of the first pair may be positioned on a first side 102e of frame 102. The first coupler 116(1) may be attached to a first leg assembly 106(1). A first coupler 116(1) may be configured to couple to a first lateral side (e.g., 202e in Figures 10 and 11) of a child vehicle (e.g., 200, 400). A first-aligned second coupler 116(2) may be positioned at a second side 102f of the frame 102. The second coupler 116(2) may be configured to couple to a second lateral side (e.g., 200, 400) of the child vehicle (e.g., 202f in Figures 10 and 11). The second coupler 116(2) may be attached to a second leg assembly 106(2). In some instances, each of the first coupler 116(1) and the second coupler 116(2) may define a bayonet 117 as shown, but the examples disclosed herein are not limited thereto.

[0081] Each bayonet 117 may be an upwardly extending protrusion. Each bayonet 117 may extend substantially along the vertical direction V. Each bayonet 117 may have a thickness along the transverse direction A, a height along the vertical direction V, and a width along the longitudinal direction L. The height may be greater than the thickness and / or the width. In some embodiments, the width may be greater than the thickness.

[0082] Each of the first coupler 116(1) and the second coupler 116(2) may define a protrusion or opening 118 configured to engage another of a protrusion or opening (e.g., 216 in Figures 10 and 11 or 446 in Figures 40A and 40B) of a child vehicle (e.g., 200, 400). Figures 2 to 4 show an example in which each coupler 116(1), 116(2) defines an opening 118 on its inner surface, which is configured to receive a protrusion (e.g., 216 in Figures 10 and 11) of a child vehicle (e.g., 200, 400). Each coupler 116(1), 116(2) may engage different lateral sides of the child vehicle (e.g., 200, 400) to restrict movement of the child vehicle along the lateral direction A. The protrusion or recess 118 of each coupler 116(1), 116(2) may be configured to engage another of the protrusion and opening (e.g., 216 of FIG. 10, 11) of the child vehicle (e.g. 200, 400) in order to restrict the movement of the child vehicle along the vertical direction V (e.g., along at least one of the upward and downward directions) and / or the longitudinal direction L.

[0083] At least one coupler may include at least one other coupler, such as a pair of infant car seat couplers 120(1), 120(2), configured to be removably coupled to the infant car seat 200. At least one infant car seat coupler 120(1), 120(2) may be configured to engage a movable latch 220 of the infant car seat 200 (see FIG. 10), which also secures the infant car seat 200 to the car seat base 500 (see FIG. 13A, 13B). Each of at least one infant car seat coupler 120(1), 120(2) may define an engagement surface configured to be engaged by the movable latch 220 of the infant car seat 200 to restrict movement of the infant car seat along at least one of the vertical direction V and the longitudinal direction L.

[0084] At least one of the infant car seat couplers 120(1), 120(2) may be offset from the first pair of couplers 116(1), 116(2) along the longitudinal direction L. For example, at least one of the infant car seat couplers 120(1), 120(2) may be positioned in front of or behind the first pair of couplers 116(1), 116(2) relative to the longitudinal direction L. At least one infant car seat coupler 120(1), 120(2) couples the infant car seat 200 to the stroller 100 in such a way that when a force is applied to the handle 226 of the infant car seat 200 (see FIG. 10), the torque applied to the pair of seat couplers 116(1), 116(2) is limited. In FIGS. 2 to 4, each infant car seat coupler 120(1), 120(2) includes a cylindrical pin having an outer curved surface that defines an engagement surface. Each cylindrical pin can be oriented such that its central axis extends in the transverse direction A. It should be understood that, in alternative instances, each mating surface can be defined by a shape other than a cylindrical pin, or the cylindrical pin can be oriented in another manner.

[0085] At least one coupler may include at least one child seat coupler 132(1), 132(2) configured to be removably coupled to a child seat 400. At least one child seat coupler 132(1), 132(2) may be identical to at least one infant car seat coupler 120(1), 120(2), or may be a separate coupler from at least one infant car seat coupler 120(1), 120(2). In some instances, at least one coupler may include a pair of child seat couplers 132(1), 132(2), each configured to be removably coupled to a child seat 400. At least one child seat coupler 132(1), 132(2) may be configured to engage a movable latch 456 of the child seat 400 (see Figures 40A, 40B). At least one of the child seat couplers 132(1), 132(2) defines an engagement surface configured to be engaged by a movable latch 456 of the child seat 400 to restrict movement of the child seat 400 along at least one of the vertical direction V and the longitudinal direction L. At least one of the child seat couplers 132(1), 132(2) may be offset along the longitudinal direction L from the first pair of couplers 116(1), 116(2). For example, at least one of the child seat couplers 132(1), 132(2) may be positioned in front of or behind the first pair of couplers 116(1), 116(2) relative to the longitudinal direction L. In one example, each infant car seat coupler 120(1), 120(2) may be positioned behind the first pair of couplers 120(1), 120(2), and each toddler seat coupler 132(1), 132(2) may be positioned in front of the first pair of couplers 116(1), 116(2). At least one toddler seat coupler 132(1), 132(2) couples the toddler seat 400 to the stroller 100 in order to limit the torque applied to the pair of seat couplers 116(1), 116(2) when a force is applied to the handle 404 of the toddler seat 400 (see FIG. 36A).

[0086] The stroller 100 may include at least one folding latch (e.g., 125 of Figures 6A to 7B further described below) configured to releasably lock the stroller 100 in an unfolded position. The stroller 100 may include an actuator (e.g., 127 of Figure 6A further discussed below) configured to actuate at least one folding latch to move at least one folding latch between an unlocked position and a locked position, in which the stroller 100 is allowed to fold and in the locked position, the stroller 100 is prevented from folding. The actuator may include a third crossbar 114(3) defining a handle 122, the handle being configured to be grasped by a caregiver to move at least one lock to an unlocked position. In some instances, the handle 122 may extend between a first leg assembly 106(1) and a second leg assembly 106(2). For example, the handle 122 may extend in a lateral direction A. In the examples of Figures 2 to 4, the handle 122 is shaped as a rod; however, it should be understood that in other examples, the handle 122 may have other suitable shapes. For example, the handle 122 may alternatively include a fabric webbing or rope (not shown) extending between the first leg assembly 106(1) and the second leg assembly 106(2), which unlocks the folding latch when the webbing or rope is pulled.

[0087] In some instances, the handle 122 may include a movable actuator body (e.g., 129 in Figure 6A discussed below), such as a movable button, configured to be engaged by a caregiver to move at least one lock (e.g., 125 in Figures 6A-7B) to an unlocked position when the movable actuator body is moved (e.g., when the movable button is pressed). The stroller 100 may be configured such that the stroller 100 can be changed from an unfolded configuration to a first folded configuration by pulling the actuating handle 122 upwards in a vertical direction. In some instances, this may be performed after the movable actuator body has been moved. In other instances (e.g., when the handle includes webbing or cord), movement of the actuator handle 122 itself may change at least one lock from a locked position to an unlocked position, and then further movement of the actuating handle 122 may change the stroller 100 from an unfolded configuration to a first folded configuration.

[0088] The stroller 100 may include at least one linkage assembly 124(1), 124(2). Figures 3 and 4 illustrate examples in which the stroller 100 includes a first linkage assembly 124(1) attached to a first side 102e of the frame 102 and a second linkage assembly 124(2) attached to a second side 102f of the frame 102. In some instances, each linkage assembly 124(1), 124(2) may be configured to drive one of the front support legs 108(1), 108(2) and one of the rear support legs 110(1), 110(2) toward each other when the stroller 100 is converted to a first folding configuration, and to drive the above to move away from each other when the stroller 100 is converted to an unfolded configuration. Each of at least one linkage assembly 124(1), 124(2) may include at least one seat coupler. For example, each of at least one linkage group 124(1), 124(2) may include one of an infant car seat coupler 120(1), 120(2) and / or one of a toddler seat coupler 132(1), 132(2). In some instances, each of at least one linkage group 124(1), 124(2) may include a support surface configured to support a child vehicle (e.g., 200, 400) thereon. Each of at least one linkage group 124(1), 124(2) may include a folding lock 125 (described in further detail below) that restricts movement of the linkage group when the folding lock 125 is in the locked position, thereby preventing the stroller 100 from changing from an unfolded configuration to a first folded configuration.

[0089] Referring specifically to Figures 5A to 5C, each linkage 124(1), 124(2) may include a first link 124a and a second link 124b. The first link 124a and the second link 124b may have inner ends, which are pivotally connected to each other at a first hinge 124c. The first link 124a may be additionally pivotally coupled to one of the front outriggers 108(1), 108(2), and the second link 124b may be additionally pivotally coupled to one of the rear outriggers 110(1), 110(2). The first link 124a and the second link 124b of each linkage 124(1), 124(2) may each be shaped as a rod or a plate, or may have any other suitable shape. Each linkage 124(1), 124(2) has a first link 124a and a second link 124b that define corresponding support surfaces 124c and 124d, which are aligned with each other when the stroller 100 is in an unfolded configuration. When the child carrier (e.g., 200) is coupled to the frame 102, the support surfaces 124c and 124d support the bottom surface of the child carrier (e.g., 200) such that the bottom surface rests on the support surfaces 124c and 124d. This prevents the child carrier from moving downward relative to the frame 102.

[0090] The third crossbar 114(3) may be coupled to at least one linkage group. For example, the third crossbar 114(3) may be coupled to a first linkage group 124(1), such as to one of the first link 124a and the second link 124b of the first linkage group 124(1). The third crossbar 114(3) may also be coupled to a second linkage group 124(2), such as to one of the first link 124a and the second link 124b of the second linkage group. The third crossbar 114(3) is configured such that when the third crossbar 114(3) moves upward relative to the first leg assembly 106(1) and the second leg assembly 106(2), the inner ends of the first link 124a and the second link 124b of each linkage group 124(1), 124(2) pivot relative to each other and move upward. This causes the outer ends of the first link 124a and the second link 124b of each linkage 124(1), 124(2) to move toward each other, thereby pulling the front support legs 108(1), 108(2) and the rear support legs 110(1), 110(2) toward each other towards the first folding configuration. Furthermore, each of the connectors 120(1) and 120(2) retracts as the front and rear support legs move toward each other. Therefore, it can be said that the stroller 100 includes at least one linkage that causes at least one connector to retract when the stroller 100 is converted to the first folding configuration.

[0091] Conversely, when the third crossbar 114(3) moves downward relative to the first leg assembly 106(1) and the second leg assembly 106(2), the inner ends of the first link 124a and the second link 124b of each link assembly 124(1), 124(2) pivot relative to each other and move downward. This, in turn, moves the outer ends of the first link 124a and the second link 124b of each link assembly 124(1), 124(2) away from each other, thereby moving the front legs 108(1), 108(2) and the rear legs 110(1), 110(2) away from each other toward the unfolded configuration. Furthermore, each of the connectors 120(1) and 120(2) extends as the front and rear legs move away from each other. Thus, it can be said that the stroller 100 includes at least one link assembly that extends at least one connector when the stroller 100 is converted to the unfolded configuration. It should be understood that, in alternative instances, the third crossbar 114(3) need not be coupled to at least one linkage group. For example, the third crossbar 114(3) may alternatively be coupled to one of the trolley legs 108(1), 108(2), 110(1), 110(2) or to hinges 112(1), 112(2).

[0092] Referring again to Figures 5A to 5C, each coupler 116(1), 116(2) may be configured to be fixed in position relative to one of the leg assemblies 106(1), 106(2) when the stroller 100 is in an unfolded configuration, thereby preventing the other coupler 116(1), 116(2) from rotating relative to the leg assemblies 106(1), 106(2). In some instances, each coupler 116(1), 116(2) may be allowed to rotate when the stroller 100 is folded into a first folded configuration. For example, each coupler 116(1), 116(2) may be configured to rotate forward toward the front end of the stroller 100 when the stroller 100 is folded into a first folded configuration so that the child seat 400 remains attached to the stroller 100, as will be further discussed below with respect to Figures 37A and 37B. The trolley 100 may include at least one stop for each coupler 116(1), 116(2), configured to restrict rotation of the couplers 116(1), 116(2) when the trolley 100 is in an unfolded configuration and to allow rotation when the trolley is in a first folded configuration. For example, the trolley 100 may include a stop 119 for each coupler 116(1), 116(2), configured to engage the couplers 116(1), 116(2) when the trolley 100 is in an unfolded configuration to restrict downward rotation of the couplers 116(1), 116(2) toward the rear end 102d of the trolley frame 102. Each stop 119 may be attached to one of the rear support legs 110(1), 110(2).

[0093] Each coupler 116(1), 116(2) may include at least one rotatable stop, such as a pair of rotatable stops 116a and 116b. Each rotatable stop 116a, 116b may engage a different side of the outrigger tube 108a of one of the front outriggers 108(1), 108(2). Each coupler 116(1), 116(2) may include a rotatable hub 116c attached to a bayonet 117 of the coupler 116(1), 116(2), which includes at least one rotatable stop 116a, 116b. The rotatable hub 116c may be rotatably fixed relative to the bayonet 117 such that rotation of the rotatable hub 116c causes rotation of the bayonet 117. When the trolley 100 is in the unfolded configuration (FIG. 5A), at least one rotatable stop 116a, 116b can be positioned to prevent the rotatable hub 116c and thus prevent at least one rotatable stop 116a, 116b and the latch 117 from rotating forward toward the front end 102c of the trolley frame 102.

[0094] When the trolley 100 is folded into the first folded configuration (FIG. 5B), the outrigger tube 108a rotates, thereby allowing the rotatable hub 116c and thus at least one rotatable stop 116a, 116b and bayonet 117 to rotate forward, as shown in FIG. 5B. At least one stop 116a, 116b engages the outrigger tube 108a to limit further forward rotation of the rotatable hub 116c, at least one stop 116a, 116b and bayonet 117. It should be noted that when the trolley is in the first folded configuration of FIG. 5B, at least one rotatable stop 116a, 116b can be positioned to allow the couplers 116(1), 116(2) to rotate downward toward the rear end 102d of the trolley frame 102.

[0095] Referring to Figures 6A to 7B, the stroller 100 may include a folding latch 125 for each of at least one of the first linkage 124(1) and the second linkage 124(2). Each folding latch 125 prevents a link, such as the first link 124a and the second link 124b, from pivoting relative to each other in the linkage 124(1) and 124(2). Each folding latch 125 may include a movable protrusion 125a configured to switch between a locked position and an unlocked position. In the locked position, the protrusion 125a engages at least one of the first link 124a and the second link 124b to prevent the first link 124a and the second link 124b from pivoting relative to each other about a hinge 124c. At least one of the first link 124a and the second link 124b may include an engagement surface 124e, which is configured to engage with a protrusion 125a. In the unlocked position, the protrusion 125a is retractable, disengaging it from at least one of the first link 124a and the second link 124b, thereby allowing the first link 124a and the second link 124b to pivot relative to each other about a hinge 124c. In some embodiments, the protrusion 125a is rotatable between a locked position and an unlocked position, as shown in Figures 7A and 7B.

[0096] Each folding latch 125 may include a latch housing 125b configured to receive a protrusion 125a. Note that in Figures 6A and 6B, a portion of the link 124b is cut away to make the latch housing 125b visible. Each latch housing 125b may pivotally couple a third crossbar 114(3) to one of the first link 124a and the second link 124b about a pivot axis AP2 or AP3. The trolley 100 may be configured to fold about a pivot axis AP2 or AP3 to transform into a second folding configuration (Figure 6C). The trolley 100 may be configured such that when the trolley 100 is in each of the unfolded configuration (Figure 6A), the first folding configuration (Figure 6B), and the second folding configuration (Figure 6C), each latch housing 125b is at least partially housed within a link of one of the link assemblies 124(1), 124(2). In this way, each latch housing 125b can occupy the space S between the end 114a of the third crossbar 114(3) and one of the first link group 124(1) and the second link group 124(2), so as to avoid any possible pinch points that would have existed in the space S in the absence of the latch housing 125b.

[0097] Briefly referring to Figures 7A and 7B, actuator 127 may include a movable actuator body 129 configured to be engaged by a caregiver to move folding latch 125 between an unlocked position and a locked position. The movable actuator body 129 is movable relative to handle 122. In one example, the movable actuator body 129 may be carried by handle 122. For example, the movable actuator body 129 may define a button configured to retract into handle 122 when pressed by a caregiver. Actuator 127 may include a linkage 131, such as a strap, wire, or cable, attached to the movable actuator body 129 and folding latch 125 such that movement of the movable actuator body 129 translates into movement of the folding latch 125 between a locked position and an unlocked position. For example, the actuator body 129 may have a ramped surface 129a that engages the ramped surface of the connecting rod 131 to translate the connecting rod 131 in the lateral direction A when the actuator body 129 moves in a direction offset at an angle from the lateral direction A (e.g., the vertical or longitudinal direction). The movement of the connecting rod 131 allows the latch protrusion 125a to rotate about a pivot 125c between a locked position and an unlocked position. The latch 125 and the actuator 127 may be implemented in another suitable manner.

[0098] It should be understood that, in alternative embodiments, at least one linkage group may be configured in a manner other than that shown. For example, in some embodiments, at least one linkage group may not define a support surface. In some embodiments, at least one linkage group may not support either of connectors 120(1) or 120(2). In some embodiments, at least one linkage group may have more than two links, and / or the links may be configured in a manner other than that shown. In some embodiments, at least one linkage group may not engage at least one folding latch 125, and at least one folding latch 125 may be located elsewhere. For example, at least one folding latch 125 may be located in at least one of hinges 112(1), 112(2) (FIG. 3).

[0099] Referring to Figures 8A to 9B, the stroller 100 can be folded from an unfolded configuration to a first folded configuration (Figures 8A to 8C) by pivoting the front outriggers 108(1), 108(2) about a first pivot axis AP1 extending in the lateral direction A relative to the rear outriggers 110(1), 110(2). In some instances, the stroller 100 can be folded from the first folded configuration (Figures 8A to 8C) to a second folded configuration (Figures 9A, 9B) about at least one other pivot axis, such as about pivot axes AP2, AP3, wherein each of the pivot axes AP2, AP3 is angularly offset from the first pivot axis AP1. For example, at least one other pivot axis AP2, AP3 can extend substantially in the vertical direction V. The stroller 100 can be folded from a first folding configuration (Figures 8A to 8C) to a second folding configuration (Figures 9A and 9B) by rotating the first leg assembly 106 (1) and the second leg assembly 106 (2) toward each other about at least one other pivot axis.

[0100] Each crossbar 114(1), 114(2), 114(3) may include at least one hinge, such as a first hinge 114d and a second hinge 114e, which are offset from each other along the length of the crossbar (e.g., along the lateral direction A). The stroller 100 is configured such that when the frame 102 is transformed into a first folding configuration, the first hinges 114b of the crossbars 114(1), 114(2), 114(3) are aligned with each other along a second pivot axis AP2, and the second hinges 114b of the crossbars 114(1), 114(2), 114(3) are aligned with each other along a third pivot axis AP3. This alignment allows the first leg assembly 106(1) to rotate about the second pivot axis AP2 toward the second leg assembly 106(2), and allows the second leg assembly 106(2) to rotate about the third pivot axis AP3 toward the first leg assembly 106(1).

[0101] As can be seen in Figures 1 and 2, the stroller 100 does not have a push rod or a push handle. When the child carrier is coupled to the stroller 100, the push handle extends upward from the support leg assemblies 106(1) and 106(2) above the child carrier (200, 400). Furthermore, as can be seen in Figures 3 and 4, the stroller 100 also does not have any frame structure extending above the support leg assemblies 106(1) and 106(2) to support the fabric seat. In fact, the stroller 100 can be configured such that when the child carrier (200, 400) is coupled to the stroller 100, no part of the stroller 100 extends above the child carrier (200, 400).

[0102] [Children's stroller basket]

[0103] Referring to Figures 43 to 45, according to one example, a stroller 100 is shown having a basket 126. The basket 126 may be formed of at least one fabric. The basket 126 may be positioned between a first leg assembly 106(1) and a second leg assembly 106(2). The basket 126 may include a front end 126a and a rear end 126b offset from each other along a longitudinal direction L. The front end 126a and the rear end 126b may be substantially closed. The basket 126 may include a first side 126c and a second side 126d offset from each other along a transverse direction A. The first side 126c may be attached to the first leg assembly 106(1), and the second side 126d may be attached to the second leg assembly 106(2). The first side 126c and the second side 126d may extend from the front end 126a to the rear end 126b. The first side 126c and the second side 126d may be substantially closed. The front end 126a and the rear end 126b can extend from the first side 126c to the second side 126d.

[0104] The basket 126 may include an upper end 126e and a lower end 126f offset from each other along a vertical direction V. The upper end 126e and the lower end 126f may extend from a front end 126a to a rear end 126b and from a first side 126e to a second side 126d. At least a portion, up to the entirety, of the upper end 126e may be open. The lower end 126e may be closed to prevent items stored therein from falling out of the basket 126. The basket 126 may define a recess between the front end 126a and the rear end 126b, between the first side 126c and the second side 126d, and between the upper end 126e and the lower end 126f.

[0105] The basket 126 may be attached to a first front support leg 108(1) and a second front support leg 108(2) and to a first rear support leg 110(1) and a second rear support leg 110(2). The rear end 126b of the basket 126 may extend in the longitudinal direction L beyond at least a portion of each of the first rear support leg 110(1) and the second rear support leg 110(2). The rear end 126b may extend in the longitudinal direction L beyond a second (i.e., rearward) crossbar 114(2). The second crossbar 114(2) may be disposed within the basket 126. A first side 126c, a second side 126d, a front end 126a, and a rear end 126b may extend above the second crossbar 114(2) such that the second crossbar 114(2) is between the front end 126a and the rear end 126b and between the first side 126c and the second side 126d. In some instances, the second crossbar 114(2) may be positioned closer to the lower end 126f than the upper end 126e.

[0106] The rear end 126b may contain a reinforcement 128. In one example, the reinforcement 128 may have a "U" shape, having a first end 128a and a second end 128b respectively attached to the first leg assembly 106(1) and the second leg assembly 106(2). The reinforcement 128 may be a piece of plastic or other flexible material. In some examples, the reinforcement 128 may be a curved rod that is housed in a tunnel (e.g., a fabric tunnel) of the basket 126. The reinforcement 128 may be positioned along the upper end 126e. The reinforcement 128 may be configured such that when the stroller 100 is transformed from an unfolded configuration (FIG. 43) to a first folded configuration (FIG. 44), the reinforcement 128 and therefore the rear end 126b of the basket 126 retract relative to the first rear leg 110(1) and the second rear leg 110(2). For example, the first end 128a and the second end 128b of the reinforcing member 128 may be pivotally attached to the first rear support leg 110(1) and the second rear support leg 110(2), respectively, such that when the stroller 100 is transformed from an unfolded configuration (FIG. 43) to a first folded configuration (FIG. 44), the reinforcing member 128 rotates about a pivot axis relative to the first rear support leg 110(1) and the second rear support leg 110(2). The pivot axis may extend in the lateral direction A. The reinforcing member 128 may also bend or move as the stroller 100 is transformed from the first folded configuration (FIG. 44) to a second folded configuration (FIG. 45). Thus, the stroller 100 can be transformed into both the first folded configuration and the second folded configuration, while the basket 126 remains attached. This is made possible, at least in part, by the fact that when the stroller 100 is folded, at least one to all (1) the basket 126 extends beyond the rear support legs 110 (1) and 110 (2) and the reinforcement 128 flexes and / or pivots.

[0107] Referring to Figures 46 to 48, according to another example, a stroller 100 is shown having a basket 126. The basket 126 has a front end 126a, a first side 126c, a second side 126d, an upper end 126e, and a lower end 126f, which are configured in a manner similar to that described above in Figures 43 to 45. The basket 126 also has a rear end 126b, which is configured differently from that described above in Figures 43 to 45. In this example, the rear end 126b extends beyond at least a portion of the rear support legs 110(1) and 110(2). The rear end 126b includes a reinforcement 128 having a planar shape. The reinforcement 128 may be a piece of plastic or other flexible material. The reinforcement 128 may extend from the upper end 126e to the lower end 126f. The reinforcement 128 may extend from the first side 126c to the second side 126d. Each of the first side 126c and the second side 126d may include at least one fold 130, such as an accordion fold, which allows the rear end 126b to be transformed between an open position (as shown) and a closed position, wherein the rear end 126b extends further in the open position from the first rear support leg 110(1) and the second rear support leg 110(2) along the longitudinal direction L than in the closed position. The stroller 100 may include at least a pair of magnets configured to hold the rear end 126b in the closed position and to be detachable to transform the basket 126 to the open position. For example, the pair of magnets may include at least one first magnet 121 disposed on the frame 102 and at least one second magnet 123 disposed on the basket 126 (e.g., on the rear end 126b or on the fabric between adjacent folds 130), the at least one second magnet being configured to engage with at least one first magnet 121. In some instances, the stroller 100 may include a pair of magnets on each side 102e and 102f of the frame 102. Each first magnet 121 may be fixed to one of the first linkage 124(1) and the second linkage 124(2), such as to the rear end of one of the first linkage 124(1) and the second linkage 124(2).

[0108] [Infant car seat with push handle]

[0109] Referring to Figures 10 and 11, a child vehicle 200 is shown according to an example. The child vehicle 200 may be located in an infant car seat (also referred to as an infant vehicle). Generally, the infant car seat 200 includes an infant car seat body 202. The body 202 defines a seat shell. The infant car seat body 202 includes an upper end 202a and a lower end 202b opposite to each other along a vertical direction V. The upper end 202a defines a recess 204 extending in that upper end toward the lower end 202b and terminating at a seat surface 206 configured to support an infant thereon. The seat surface 206 may include a seat back 206a and a seat base 206b. Note that the underside of the seat base 206b is shown in Figure 11. Although not shown, the infant car seat 200 may include textiles disposed within the recess 204, which is configured to provide cushioning for the infant.

[0110] The lower end 202b has a bottom surface 208, which is configured to rest on the vehicle seat floor when the infant car seat 200 is installed in a vehicle. The infant car seat body 202 includes a first end or front end 202c and a second end or rear end 202d opposite to each other along the longitudinal direction L. The front end 202c is spaced apart from the rear end 202d along the forward direction. The front end 202c is configured to face the seat back of the vehicle seat on which the infant car seat 200 is installed. Conversely, the rear end 202d is configured to face away from the seat back of the vehicle seat on which the infant car seat 200 is installed. When a child is sitting in the infant car seat body 202, the child's head is positioned closer to the rear end 202d, and the child's feet are positioned closer to the front end 202c. The infant car seat body 202 includes a first side 202e and a second side 202f opposite to each other along the lateral direction A.

[0111] In some instances, the bottom surface 208 may be curved as it extends along the longitudinal direction L, such that when the infant car seat 200 is supported on the floor, the infant car seat 200 may rock back and forth along the longitudinal direction L. For example, the bottom surface 208 may be curved such that when the infant car seat 200 is placed on a flat surface, a portion of the bottom surface 208 between the front end 202c and the rear end 202d contacts the flat surface, and the bottom surface 208 is spaced apart from the flat surface at one or both of the front end 202c and the rear end 202d. However, it should be understood that the bottom surface 208 need not be curved.

[0112] In some instances, the lower end 202b may include a first rail 210(1) and a second rail 210(2) spaced apart from each other along the transverse direction A. The first rail 210(1) may be defined at a first side 202e, and the second rail 210(2) may be defined at a second side 202f. Each of the first rail 210(1) and the second rail 210(2) may have an inner surface and an outer surface opposite each other along the transverse direction A. Each of the first rail 210(1) and the second rail 210(2) may have a length along the longitudinal direction L, which is greater than the width of the rails 210(1) and 210(2) along the transverse direction A. Thus, each rail 210(1) and 210(2) may extend along the longitudinal direction L. The lower end 202b may define a space 212 between the first rail 210(1) and the second rail 210(2). For example, the inner surface of the first track 210(1) may be opposite to the inner surface of the second track 210(2) to define a space 212 therebetween. Each track 210(1), 210(2) may include a portion of the bottom surface 208. It should be understood that, in alternative instances, the lower end 202b need not have the first track and the second track.

[0113] The infant car seat 200 may include at least one coupler configured to couple the infant car seat 200 to a stroller 100 such that movement of the infant car seat 200 relative to the stroller 100 is restricted along at least one of the vertical direction V, the longitudinal direction L, and the lateral direction A. Figures 10 and 11 show a particular example of a coupler used to couple the infant car seat 200 to the stroller 100; however, it should be understood that the infant car seat 200 may be coupled to the stroller 100 using any other suitable coupler or one or more. In some instances, as shown in Figures 10 and 11, at least one coupler may include a first pair of couplers 214(1), 214(2). The first coupler 214(1) of the first pair may be positioned at a first side 202e of the infant car seat 200. The second coupler 214(2) of the first pair may be positioned at a second side 202f of the infant car seat 200. Each of the first coupler 214(1) and the second coupler 214(2) may define a protrusion or opening 216 configured to engage the other of the protrusions and openings 118 of the stroller 100. Each side 202e, 202f and each coupler 214(1), 214(2) may engage different lateral sides of the stroller 100 to restrict movement of the child vehicle along the lateral direction A. The protrusion or recess 216 of each coupler 214(1), 214(2) may be configured to engage the other of the protrusions and openings 118 of the stroller 100 along the lateral direction A to restrict movement of the infant car seat 200 along the vertical direction V (e.g., along at least one of the upward and downward directions).

[0114] Figures 10 and 11 illustrate an example in which each coupler 214(1), 214(2) includes a movable latch defining a protrusion 216 extending from one side of the infant car seat 200. The first coupler 214(1) may include a protrusion 216 extending from a first side 202e of the infant car seat 200. The protrusion 216 is movably attached to the car seat body 202 such that it is configured to retract into and extend from the first side 202e of the car seat body 202. The protrusion 216 of the first coupler 214(1) may be spring-loaded, biased toward an extended position. The first coupler 214(1) may be configured to couple to a first coupler 116(1) of a stroller 100. For example, the protrusion 216 of the first coupler 214(1) can be configured to be housed in the opening 118 of the first coupler 116(1) of the stroller 100.

[0115] The second coupler 214(2) of the first pair can be positioned on the second side 202f of the infant car seat 200. The second coupler 214(2) may include a protrusion 216 extending from the second side 202f of the infant car seat 200. The protrusion 216 is movably attached to the car seat body 202, such that the protrusion 216 is configured to retract into and extend from the second side 202f of the car seat body 202. The protrusion 216 of the second coupler 214(2) may be spring-loaded, such that it is biased toward the extended position. The second coupler 214(2) may be configured to couple to the second coupler 116(2) of the stroller 100. For example, the protrusion 216 of the second coupler 214(2) can be configured to be housed in the opening 118 of the second coupler 116(2) of the stroller 100.

[0116] At least one coupler may include at least one other coupler, such as a second pair of couplers 218(1), 218(2). Each of the at least one other coupler 218(1), 218(2) may include a movable latch 220 configured to engage an engagement surface of the stroller 100 (e.g., 120(1), 120(2)) to restrict movement of the infant car seat 200 relative to the stroller 100 in at least one of the vertical direction V and the longitudinal direction L. Each of the at least one other coupler 218(1), 218(2) may be offset from the first pair of couplers 214(1), 214(2) in the longitudinal direction L. For example, each of the at least one other coupler 218(1), 218(2) may be positioned closer to the front end 202c than the first pair of couplers 214(1), 214(2). At least one of the other couplers 218(1), 218(2) may be positioned in front of the handle hubs 228(1), 228(2) (discussed below). At least one of the other couplers 218(1), 218(2) may be positioned at the lower end 202b of the infant car seat 200, such as on the lower side of the infant car seat 200.

[0117] Figures 10 and 11 illustrate a particular example in which each movable latch 220 defines a movable hook that engages with a corresponding one of the couplers 120(1) and 120(2) of the stroller 100. Each movable latch 220 may be housed in a recess extending into the lower end 202b of the infant car seat 200, such as extending into the bottom surface 208. It should be understood that, in alternative embodiments, each movable latch 220 may be defined by a shape other than a hook, or may be oriented in another manner. For example, each movable latch 220 may be a movable bar, and each coupler 120(1) and 120(2) of the stroller 100 may define a hook for receiving the movable bar. Couplers 218(1) and 218(2) may be identical couplers for attaching the infant car seat 200 to a car seat base (500 in Figures 13A and 13B) to mount the infant car seat 200 to a vehicle seat. In other words, each coupler 218(1) and 218(2) may be configured to be removably coupled to a coupler (508 in Figures 13A and 13B) of the car seat base to prevent the infant car seat 200 from being removed from the car seat base (500 in Figures 13A and 13B) in an upward direction. At least one other coupler 218(1) and 218(2) may be configured to engage a coupler in a downward direction (e.g., 508 in Figures 13A and 13B).

[0118] Briefly referring to Figures 13A and 13B, a car seat base 500 includes a lower end 502 configured to rest on a vehicle seat when the car seat base 500 is installed in a vehicle. The car seat base 500 includes an upper end 504 configured to support an infant car seat 200. In some embodiments, the car seat base 500 may define at least one recess 506 extending toward the lower end 502 into the upper end 504. The recess 506 may be configured to receive a lower portion of the infant car seat 200 therein. The car seat base 500 may include at least one coupler 508, such as a pair of couplers 508 offset from each other in a lateral direction A. Each coupler 508 may be disposed within at least one recess 506 of the car seat base 500. Each coupler 508 may be configured to couple to one of the couplers 218(1), 218(2) of the infant car seat 200 to prevent the infant car seat 200 from being removed in the vertical direction V. The couplers 508 may be configured in any suitable manner. In some instances, each coupler 508 may include a rod configured to engage by a latch defined by one of the couplers 218(1), 218(2) of the infant car seat 200.

[0119] Referring back to Figures 10 and 11, the infant car seat 200 may include at least one actuator 224 configured to be actuated by a caregiver to switch the couplers 214(1), 214(2) and / or the couplers 218(1), 218(2) of the infant car seat 200 between an unlocked configuration and a locked configuration. For example, at least one actuator 224 may be configured to be actuated by a caregiver to: (1) release the couplers 214(1), 214(2) of the infant car seat 200 from the couplers 116(1), 116(2) of the stroller 100; and / or (2) release the couplers 218(1), 218(2) of the infant car seat 200 from the couplers 120(1), 120(2) of the stroller 100. Additionally, at least one actuator 224 may be configured to be actuated by a caregiver to release the couplers 218(1), 218(2) of the infant car seat 200 from the coupler 508 of the base 500. For example, actuator 224 may be configured to retract the couplers 214(1) and 214(2) of the infant car seat 200 into the seat body 202 when actuated by a caregiver. Actuator 224 may be configured to move the movable latch 220 of couplers 218(1), 218(2) when actuated by a caregiver to disengage from the couplers 120(1), 120(2) of the stroller 100. In some instances, actuator 224 may include a handle engaged by a caregiver to actuate actuator 224. In some instances, the actuator 224 may be positioned on the underside of the seat body 202 near the rear end 202d of the seat body 202. However, it should be understood that the actuator 224 may be positioned in other locations.

[0120] Referring to Figures 10 to 12B, the infant car seat 200 may include a handle 226. The infant car seat handle 226 can be configured to switch between a retracted position (Figure 12A) and an extended position (Figure 12B). In the retracted position, the handle 226 can be gripped by a caregiver to carry the infant car seat 200. In the extended position, the handle 226 can be used to push the stroller 100 when the car seat 200 is coupled to it as shown in Figure 1. Therefore, the infant car seat handle 226 may be referred to as a push handle and a carrying handle. The handle 226 may have a first side bar 227a and a second side bar 227b spaced apart from each other along the lateral direction A. The handle 226 may define a space between the first side bar 227a and the second side bar 227b. This space may have a width greater than the width of the car seat body 202. The handle 226 may have a gripping bar 227c, which defines a surface to be grasped by a caregiver to lift and / or push the infant car seat 200. The gripping bar 227c may extend from the first handle side bar 227a to the second handle side bar 227b.

[0121] The infant car seat 200 may include a first handle hub 228(1) and a second handle hub 228(2). The first handle hub 228(1) may be configured to couple a first handle side bar 227a of the infant car seat handle 226 to a first side 202e of the car seat body 202, such that the handle 226 can be selectively rotated relative to the car seat body 202. Similarly, the second handle hub 228(2) may be configured to couple a second handle side bar 227b of the infant car seat handle 226 to a second side 202f of the car seat body 100, such that the handle 226 can be selectively rotated relative to the car seat body 202. The infant car seat handle 226 may have a first handle portion 226a, a second handle portion 226b, and a third handle portion 226c, the third handle portion being attached to the first handle portion 226a and the second handle portion 226b such that the third handle portion 226c is retractable relative to each of the first handle portion 226a and the second handle portion 226b. The first handle portion 226a extends from a first hub 228(1) and defines a portion of a first handle side bar 227a. The second handle portion 226b extends from a second hub 228(2) and defines a portion of a second handle side bar 227b. Each handle portion 226a and 226b may have a tubular shape. The third handle portion 226c may be tubular and have a "U" shape, wherein the end of the "U" shape is attached to the first handle portion 226a and the second handle portion 226b. For example, the "U"-shaped end can be housed within the first handle portion 226a and the second handle portion 226b to translate within them. The bottom of the "U" shape can define a grip bar 227c. In some instances, the infant car seat handle 226 may have a handle 226d mounted on the third handle portion 226c for caregiver gripping. The handle 226d may have a soft surface, such as a rubberized surface.

[0122] Referring to Figure 14, the infant car seat handle 226 can be configured to selectively rotate between a plurality of different positions. For example, the handle 226 can be configured to rotate to a first rotation position (position A), wherein as the handle 226 extends toward the front end 202c of the seat body 202, the handle 226 tilts upward and away from the seat body 202. The first rotation position can be oriented to allow a caregiver to use the handle 226 to push the stroller when the car seat 200 is coupled to the stroller 100. The first position can be referred to as the "tilted position" or "pushing position". The handle 226 can be configured to rotate to a second rotation position (position B), wherein the handle 226 extends upward along the vertical direction V. The second rotation position can be oriented to allow a caregiver to use the handle 226 to carry the infant car seat 200. The second rotation position can be referred to as the "upright position" or "carrying position". Handle 226 can be configured to rotate to a third rotational position (position C), wherein as handle 226 extends toward the rear end 202d of seat body 202, handle 226 tilts upward and away from seat body 202. Handle 226 can be configured to rotate to a fourth rotational position (position D), wherein handle 226 extends along the longitudinal direction L toward the rear end 202d of vehicle seat 200. Handle 226 can be configured to rotate to a fifth rotational position (position E), wherein as handle 226 extends toward the rear end 202d of vehicle seat 200, handle 226 extends downward away from vehicle seat body 202. It should be understood that, in alternative embodiments, one or more of the third, fourth, and fifth rotational positions may be omitted.

[0123] The operation of handle 226 will now be described. Generally, the infant car seat 200 may be configured such that handle 226 can be transferred from a retracted position to an extended position when it is in a first rotational position (also referred to as the push position or position A), but not when it is in one or more other positions. In some instances, the infant car seat 200 may be configured such that handle 226 can be transferred from the retracted position to the extended position only when it is in the first rotational position (position A). The infant car seat 200 may include at least one handle extension stop (e.g., 244 in Figures 20 to 22, further discussed below), which is configured to prevent handle 226 from transferring from the retracted position to the extended position when it is not in the push position. Therefore, the infant car seat 200 may be configured such that handle 226 is prevented from transferring to the extended position when it is in the second, third, fourth, and fifth rotational positions illustrated in Figure 14. The infant car seat 200 may include at least one handle extension lock (e.g., 246 in Figures 23 to 25, further discussed below), configured to selectively lock the handle 226 in an extended and retracted position when the handle 226 is in the push position. When the handle 226 is in the push position, the handle extension lock can be actuated by a caregiver to switch between a locked and unlocked position, in which the handle 226 is prevented from extending or retracting, and in the unlocked position, the handle 226 is allowed to extend or retract. If the caregiver attempts to actuate the handle extension lock when the handle 226 is not in the push position, a handle extension stop (e.g., 244 in Figures 20 to 22) can prevent the handle 226 from extending.

[0124] The infant car seat 200 may be configured to prevent rotation of the handle 226 when it is in the extended position. The infant car seat 200 may include at least one handle rotation stop (e.g., 242 in Figures 18 and 19, further discussed below) configured to prevent rotation of the handle 226 when it is in the extended position. Therefore, when the handle 226 is in the extended position as illustrated in Figure 14, rotation to a second, third, fourth, and fifth rotation position is prevented. The infant car seat 200 may include at least one handle rotation lock (e.g., 230 in Figure 15, further discussed below) configured to be actuated by a caregiver when the handle 226 is in the retracted position to selectively lock the handle 226 in different rotation positions. The handle rotation lock is movable between a locked position and an unlocked position, in which rotation of the handle 226 from the selected rotation position is prevented, and in the unlocked position, rotation of the handle 226 to another rotation position is permitted. If a caregiver attempts to actuate the handle rotation lock while the handle 226 is in the extended position, the handle rotation stop (e.g., 242 in Figures 18 and 19) will prevent the handle 226 from rotating.

[0125] Turning more specifically to Figures 15 to 17, an example of a rotary lock 230 is shown, implemented within a handle hub 228(2). It should be understood that another rotary lock 230 may also be implemented within another handle hub 228(1). Furthermore, it should be understood that the rotary lock 230 may be implemented in another suitable manner. The rotary lock 230 includes a locking plate 234 that defines a plurality of rotational positions of the handle 226. For example, the locking plate 234 may have a surface defining a slot 236 therein. The slot 236 may have a circular or partially circular portion 236a and a plurality of grooves 236b that are open to the circular or partially circular portion 236a and circumferentially spaced from each other along the length of the slot 236. Each groove 236b may correspond to a different rotational position of the handle 226 (e.g., positions A to E). The rotary lock 230 may include a rotary latch 238 having a protrusion 238a, such as a pin, extending therefrom into a slot 236. The protrusion 238a may be configured to be selectively received in a groove 236b to lock the handle 226 in different rotational positions.

[0126] In an alternative example (not shown), the rotary latch 238 may define at least one recess, and the locking plate 234 may define a plurality of protrusions spaced circumferentially from each other. At least one recess of the rotary latch 238 may be configured to selectively receive the protrusions to selectively lock the handle 226 in a plurality of rotational positions. Thus, it can be said that the locking plate may define a plurality of grooves or protrusions, and the rotary latch may define at least one protrusion or groove configured to selectively engage such grooves or protrusions to selectively lock the handle in different rotational positions.

[0127] Rotary latch 238 is configured to switch between a locked position (FIG. 16) and an unlocked position (FIG. 17). In the locked position, rotary latch 238 engages locking plate 234 (e.g., protrusion 238a is received in a groove in groove 236b corresponding to one of the rotational positions). In the unlocked position, rotary latch 238 disengages from locking plate 234 (e.g., protrusion 238a moves out of one of the grooves 236b into a circular or partially circular portion 236a of slot 236). Rotary latch 238 can be configured to translate along the axis of one of the first handle portions 226a and the second handle portions 226b, such that rotary latch 238 disengages from locking plate 234 (e.g., protrusion 236a can be removed from one of the grooves 236), thereby allowing handle 226 to rotate. Handle 226 can then be rotated to another rotational position. Rotary latch 238 (and protrusion 238a) is rotatably fixed to handle 226 such that rotation of handle 226 causes rotary latch 238 (and protrusion 238a) to rotate correspondingly relative to locking plate 234. Both handle 226 and rotary latch 238 can be configured to rotate about pivot 240. Pivot 240 defines a pivot axis extending in the lateral direction A. Rotary latch 238 defines a slot 238b that receives pivot 240 such that as rotary latch 238 changes between a locked position and an unlocked position, pivot 240 translates within slot 238b. When handle 226 is rotated to another rotational position, rotary latch 238 (and protrusion 238a) can move to the locked position, wherein rotary latch 238 engages locking plate 234 (e.g., protrusion 238a is received in a groove 236b corresponding to the other rotational position). The rotary latch 238 can be spring-biased toward the locked position such that when the rotary actuator 232 is released, the rotary latch 238 engages the locking plate 234 (e.g., the protrusion 238a of the rotary latch 238 moves into one of the grooves 236b).

[0128] The infant car seat 200 may include a rotary actuator 232 configured to be actuated by a caregiver to move at least one rotary lock 230 from a locked position (FIG. 16) to an unlocked position (FIG. 17), in which the handle 226 is prevented from rotating and in the unlocked position, the handle 226 is allowed to rotate. The rotary actuator 232 includes a movable body 235 defining an engagement surface 235a (shown in FIG. 15) configured to be engaged by a caregiver to actuate the rotary actuator 232. In one example, the movable body 235 may be shaped as a handle disposed around one of a first handle portion 226a and a second handle portion 226b and configured to translate along a lower handle portion 226a. The movable body 235 may have a tubular or other suitable shape, such as a sleeve, and the engagement surface 235a may be the outer surface of the rotary actuator. The rotary actuator 232 may include a wire or cable 236 extending from the movable body 235 to the rotary latch 238. Movement of the movable body 235 away from the hub 228(2) along the selection direction DS causes a corresponding movement of the wire or cable 236 along the selection direction DS, which causes a corresponding movement of the rotary latch 238 along the selection direction DS to disengage the rotary latch 238 from the locking plate 234 (e.g., to remove the protrusion 238a from one of the grooves 236b of the locking plate 234). It should be understood that, in alternative embodiments, the rotary actuator 232 may be configured in another suitable manner. For example, the movable body 235 may be implemented as a button rather than a handle. As another example, the movable body 235 may be located in another position, such as at the bottom of the "U" shape of the third handle portion 226c (i.e., on the grip bar 227c) or on one of the handle hubs 228(1), 228(2).

[0129] Referring to Figures 18 and 19, the rotary stop 242 is configured to prevent the handle 226 from rotating when it is in the extended position. Note that the rotary stop 242 is concealed in Figures 15 through 17 to make the rotary latch 238 more clearly visible. The rotary stop 242 can be configured to move between (i) a blocking position (Figure 19) and (ii) a releasing position (Figure 18), in which the stop 242 interferes with the rotary latch 238 to prevent it from moving to the unlocked position (thereby preventing the handle 226 from rotating), and in the releasing position, the interference between the stop 242 and the rotary latch 238 is removed, allowing the rotary latch 238 to move to the unlocked position (thereby allowing the handle 226 to rotate). Figures 18 and 19 show one example of the rotary stop 242; however, it should be understood that the rotary stop 242 can be implemented in any other suitable manner.

[0130] The rotary stop 242 may have a first engagement surface 242a, which is configured to engage the rotary latch 238 to interfere with the rotary latch 238 when in the blocking position. The rotary stop 242 may have a second engagement surface 242b, which is configured to engage with the third handle portion 226c to move the rotary stop 242 to the release position. Specifically, the third handle portion 226c is telescopic relative to the first handle portion 226a and the second handle portion 226b between an extended position and a retracted position as described above. As shown in FIG18, when the third handle portion 226c is in the retracted position, the third handle portion 226c may engage the second engagement surface 242b to move the rotary stop 242 to the release position. Furthermore, as shown in FIG19, when the third handle portion 226c is in the extended position, the third handle portion 226c may be spaced apart from the second engagement surface 242b, thereby allowing the rotary stop 242 to move to the blocking position. The rotation stop 242 can be spring-biased toward the blocking position. The rotation stop 242 can be configured to rotate about the pivot 240.

[0131] Referring to Figures 20 to 22, the handle extension stop 244 is configured to prevent the handle 226 from extending when it is not in the push position (i.e., not in position A of Figure 14). The handle extension stop 244 can be configured to move between a release position (Figures 20 and 21) and a blocking position (Figure 22). For example, the handle extension stop 244 can be configured to rotate about a rotation axis between the release position and the blocking position. The handle extension stop 244 and the rotation axis can be housed within one of the handle hubs 228(1) and 228(2). In the blocking position, the handle 226 is in a position other than the push position, and the handle extension stop 244 prevents the handle 226 from moving to the extension position. For example, the handle extension stop 244 may include a protrusion 244a that, when the handle extension stop 244 is in the blocked position (FIG. 22), extends through an opening in one of the first handle portion 226a and the second handle portion 226b and into the third handle portion 226c. The protrusion 244a prevents the third handle portion 226c from extending. The protrusion 244a may be located in one of the first handle hub 228(1) and the second handle hub 228(2). By rotating the handle 226 to the pushed position, the handle extension stop 244 moves to the released position (FIGs. 20 and 21). In the released position, the protrusion 244a is removed from the third handle portion 226c, thereby allowing the handle 226 to extend. The handle extension stop 244 may be spring-biased toward the unlocked position. When the handle extension stop 244 is in the released position, the handle extension lock 246 (discussed below) is in the unlocked position, allowing the handle 226 to move from the retracted position to the extended position. The handle extension stop 244 can be configured to prevent the handle 226 from extending when the handle 226 is in the lifting position (position B), regardless of whether the handle extension lock 246 is in the locked or unlocked position.

[0132] The handle extension stop 244 may have a first side defining a protrusion 244a and a second side 244b opposite to the first side 244a. The handle extension stop 244 may be configured such that, as the handle 226 is rotated, the second side 244b of the handle extension stop 244 travels along the inner surface of a corresponding one of the handle hubs 228(1), 228(2). The inner surface impedes outward rotation of the handle extension stop 244, thereby holding the handle extension stop 244 in a blocked position. When the handle 226 is rotated to a selected position (e.g., the push position shown in Figures 20 and 21), the second side 244b of the handle extension stop 244 aligns with an opening 245 in the inner surface, thereby allowing the handle extension stop 244 to rotate outward at least partially through the opening to a released position. It should be noted that the handle extension stop 244 can be completely housed within the housing of one of the corresponding handle hubs 228(1) and 228(2), and the outer part of the housing is hidden in Figure 20, so that the interior of the handle hub is visible.

[0133] Referring to Figures 23 to 25, a handle extension lock 246 is configured to selectively lock the handle 226 in both a retracted and extended position. The handle extension lock 246 may be implemented in one of the first handle portion 226a and the second handle portion 226b. It should be understood that another handle extension lock 246 may also be implemented in the other of the first handle portion 226a and the second handle portion 226b. Furthermore, although Figures 23 to 25 show an exemplary handle extension lock 246, it should be understood that the handle extension lock 246 may be implemented in another suitable manner.

[0134] The handle extension lock 246 may include a handle extension latch 248 configured to move between a locked position (FIG. 25) and an unlocked position. In the locked position, latch 248 prevents the handle 226 from changing between an extended position and a retracted position. In the unlocked position, when the handle 226 is in a first rotational position (i.e., when the handle extension stop 244 is in the released position), the handle 226 is allowed to change between the extended and retracted positions. When the handle extension stop 244 is in the blocking position, the handle 226 cannot extend, regardless of whether the handle extension lock 246 is in the locked or unlocked position.

[0135] The handle extension latch 248 may include a protrusion 248a configured to move between a locked position and an unlocked position. The protrusion 248a may move in a direction offset at an angle (such as perpendicular to) the axis AH of the handle 226. In the locked position, the protrusion 248a extends into an opening in one of the first handle portions 226a and the second handle portion 226b and into an opening in the third handle portion 226c, such that the protrusion 248a prevents the third handle portion 226c from extending. It should be noted that in some embodiments, the handle portions 226a, 226b may include a plurality of openings offset from each other along their respective axes, and each opening may correspond to a different extension position. In the unlocked position, the protrusion 248a is removed from the opening in the third handle portion 226c, thereby allowing the third handle portion 226c to extend or retract.

[0136] The handle extension lock 246 may include a latch guide 250 configured to guide movement of the latch 248 between a locked position and an unlocked position. The latch guide 250 may be configured to translate toward and away from one of the hubs 228(1), 228(2) along a selection direction DS along the axis AH of the handle 226. The latch guide 250 may include a guide surface that guides a corresponding surface of the latch 248. For example, the latch guide 250 may include a slot 250a offset at an angle to the selection direction DS, and the latch 248 may include a pin 248b received in the slot 250a. When the latch guide 250 moves away from one of the hubs 228(1) and 228(2) along the selection direction, the pin 248b translates along the slot 250a, thereby causing the protrusion 248a to move out of the opening in one of the first handle portion 226a and the second handle portion 226b and out of the third handle portion 226c (i.e., moving the latch 248 to the unlocked position). When the latch guide 250 moves towards one of the hubs 228(1) and 228(2) along the selection direction, the pin 248b translates along the slot 250a, thereby causing the protrusion 248a to move into the opening in one of the first handle portion 226a and the second handle portion 226b and into the third handle portion 226c (i.e., moving the latch 248 to the locked position).

[0137] The infant car seat 200 may include a handle extension actuator 252 (labeled in FIG. 24) configured to be engaged by a caregiver to move a handle extension latch 248 between a locked position and an unlocked position. The handle extension actuator 252 includes a movable body 254 having an engagement surface 254a configured to be engaged by a caregiver to actuate the handle extension actuator 252. In one example, the movable body 254 defines a button that defines the engagement surface 254a. The button is actuated by pressing it into a handle 226, such as a third handle portion 226c or another handle portion, along the actuation direction DA.

[0138] The handle extension actuator 252 may include a link 258, such as a wire or cable, extending from the movable body 254 to the handle extension lock 246. The handle extension actuator 252 may be configured such that movement of the movable body 254 by a caregiver causes a corresponding movement of the link 258, thereby shifting the handle actuated lock 246 between a locked and unlocked position. The handle extension actuator 252 may be configured to convert translational movement of the movable body 254 along the operating direction DA into translational movement of the link 258 along the handle 226. For example, at least one ramped surface 254b may be defined on the inner side of the movable body 254, and the handle extension actuator 252 may include at least one wedge 256 having at least one ramped surface 256a engaging at least one ramped surface 256b of the movable body 254. The handle extension actuator 252 can be configured such that when the movable body 254 is pressed by a caregiver, at least one ramped surface 254b of the movable body 254 translates along at least one ramped surface of at least one wedge 256, thereby moving at least one wedge 256 in a direction perpendicular to the direction of action DA. This, in turn, moves the linkage 258 along the handle 226 to move the handle actuation lock 246. It should be understood that in other embodiments, the handle extension actuator 252 can be implemented in another suitable manner. For example, the handle extension actuator 252 can be implemented as a handle instead of a button, and / or can be implemented in another position, such as along one of the first handle portion 226a and the second handle portion 226b.

[0139] [A cradle or portable crib with a push handle]

[0140] Although not shown, according to some examples, the child carrier may be a cradle or a portable crib. The cradle or portable crib may have a body and / or frame as known in the art. The cradle or portable crib may have a handle configured as discussed above with respect to the infant car seat 200, such that the handle operates in the manner described above with respect to the handle 226 of the infant car seat 200. Furthermore, the cradle or portable crib may include couplers similar to couplers 214(1) and 214(2), and, where applicable, couplers similar to couplers 218(1) and 218(2). It should be understood that the description above of couplers 214(1), 214(2), 218(1) and 218(2) is equally applicable to the cradle or portable crib.

[0141] [Travel Organizer]

[0142] Turning now to Figures 29 through 33, the travel system 10 may include a travel organizer 300, which may be configured to hold at least one item such as a beverage container, mobility device, or other items belonging to a caregiver. The organizer 300 may be configured to be removably coupled to a handle 226 of a child vehicle (e.g., 200, 400). For example, the organizer 300 may be configured to be coupled to the handle 226 in the space between a first handle side bar 227a and a second handle side bar 227b, and between a grip bar 227c and the child vehicle seat. It should be understood that the organizer 300 may be configured to be coupled to any suitable handle of any suitable child vehicle (e.g., any infant car seat, toddler seat, cradle, or portable crib).

[0143] The organizer 300 may have a first organizer side 300a and a second organizer side 300b offset from each other along the lateral direction A. In some instances, the organizer 300 may have a length along the lateral direction A that is greater than the width of the organizer 300 along the longitudinal direction L and / or the height of the organizer 300 along the vertical direction V.

[0144] The organizer 300 may include a bracket 302 and a storage container 304 coupled to the bracket 302 and disposed below the bracket. The bracket 302 may be formed of a suitable rigid material such as a polymer or other suitable material. The bracket 302 may have an upper bracket end 302a defining an upper surface and a lower bracket end 302b spaced apart from the upper bracket end 302a along a vertical direction V. The bracket 302 may define at least one bracket opening, such as a plurality of bracket openings, extending toward the lower bracket end 302b into the upper bracket end 302a. For example, the bracket 302 may define a circular bracket opening 302c extending into the upper bracket end 302a. The size and shape of the circular bracket opening 302c may be configured to receive a beverage container, such as a can, bottle, or cup. As another example, the bracket 302 may additionally or alternatively define a bracket opening 302d, which defines a recess extending into the upper end 302a of the bracket and closing at the bottom of the bracket opening 302d. As yet another example, the bracket 302 may additionally or alternatively define a bracket opening 302e, which defines a through hole extending fully through the bracket 302 (i.e., through the upper end 302a and the lower end 302b of the bracket), such that the bracket opening 302e is open to the storage container 304 below the bracket 302. In some examples, the bracket 302 may include a cover 306 that closes to cover at least one of the bracket openings and opens to allow a caregiver to access the contents of at least one of the bracket openings.

[0145] The storage container 304 may have an upper end 304a and a lower end 304b spaced apart from the upper end 304a along a vertical direction V. The upper end 304a may define at least one container opening 304c, which extends in the upper end and terminates before the lower end 304b, such that the bottom of the at least one container opening 304c is closed. The at least one container opening 304c may be aligned vertically with at least one of the openings of the bracket 302. For example, the at least one container opening 304c may be aligned with a bracket opening 302e, such that an item can be placed into the at least one container opening 304c through the bracket opening 302e. In some instances, the at least one bracket opening 302e may be aligned vertically with all bracket openings.

[0146] In some instances, the bracket 302 and the storage container 304 may each have a cross-sectional shape in a plane perpendicular to the vertical direction, wherein the cross-sectional shapes of the bracket 302 and the storage container 304 conform to and / or match each other. In alternative instances, the bracket 302 may have a cross-sectional shape larger than the cross-sectional shape of the storage container 304 disposed below only a portion of the bracket 302. When the bracket 302 is coupled to the storage container 304, the bracket 302 may serve as the top of the storage container 304.

[0147] Briefly referring to Figures 34 and 35, in some embodiments, the organizer 300 can be configured to switch between a compact configuration (Figure 34) and an expanded configuration (Figure 35). Specifically, the bracket 302 is movably coupled to the storage container 304, allowing the vertical distance between the bracket 302 and the storage container 304 to be selectively increased and decreased. In other words, the organizer 300 can switch from a compact configuration to an expanded configuration by increasing the distance between the bracket 302 and the storage container 304, and from an expanded configuration to a compact configuration by decreasing the distance between the bracket 302 and the storage container 304. When the organizer 300 is in a compact configuration, the bracket 302 and the storage container 304 can contact each other. Compared to when the organizer 300 is in a compact configuration, when the organizer 300 is in an expanded configuration, the organizer 300 has a larger internal storage capacity.

[0148] The organizer 300 may include a flexible material 308 coupled to a bracket 302 and a storage container 304. The flexible material 308 may be a fabric, such as a mesh fabric, or any other suitable material. In one example, the storage container 304 may be formed of a semi-rigid material such as ethylene-vinyl acetate (EVA), which has a rigidity lower than that of the bracket 302 but higher than that of the flexible material 308, and the flexible material 308 may be a fabric thermoformed to the storage container 304. The flexible material 308 may have a tubular shape, defining an upper end 308a and a lower end 308b offset from each other along a vertical direction V. The flexible material 308 may define a storage space extending from the upper end 308a to the lower end 308b. The upper end 308a may be coupled to the bracket 302, such as the lower end 302b of the bracket 302. The lower end 308b may be coupled to the storage container 304, such as to the upper end 304a of the storage container 304. Alternatively, the lower end 308b may surround the lower end 304b of the storage container 304.

[0149] When the organizer 300 is in an unfolded configuration, the flexible material 308 defines the side of the organizer 300 to accommodate items within the storage space. When the organizer 300 is in a compact configuration, the flexible material 308 can fold inside the organizer 300. Although not shown, in some instances, the flexible material 308 may define an access opening on one side, between the open upper end 308a and the lower end 308b, to allow a caregiver to access the storage space within the flexible material 308. Alternatively, the caregiver may access the storage space by defining an opening 203e that extends through a through-hole in the bracket 302.

[0150] Organizer 300 may include locking element 310 configured to selectively secure organizer 300 in a compact configuration. For example, locking element 310 may include a zipper having: a first strap portion 310a having a first plurality of teeth; and a second strap portion 310b having a second plurality of teeth configured to engage with the first plurality of teeth. Carrier 302 may include the first strap portion 310a, which may be attached to the body of carrier 302, such as the lower end 302b of carrier 302. Storage container 304 may include the second strap portion 310b, which may be attached to the body of storage container 304, such as the upper end 304a of storage container 304. It should be understood that, in alternative embodiments, organizer 300 may be implemented with locking elements 310 other than zippers, such as snaps, buttons, toggle latches, or any other suitable locking element capable of securing organizer 300 in a compact configuration.

[0151] Referring back to Figures 31 and 32, as discussed above, the organizer 300 may be configured to be removably attached to the handle 226 of the infant car seat 200. The organizer 300 may define a first coupler 312(1) at a first organizer side 300a, which is configured to engage a first coupler 229 (see Figure 26) of a first handle side bar 227a of the handle 226 to couple the first organizer side 300a to the first handle side bar 227a. The first coupler 312(1) of the organizer 300 may define at least one of the protrusions and openings, and the first coupler of the handle 226 may define the other of the protrusions and openings, which is configured to mate with the first coupler 312(1). Similarly, the straightener 300 may define a second coupler 312(2) at the second straightener side 300b, which is configured to engage the second coupler 229 of the second handle side bar 227b of the handle 226 to couple the second straightener side 300b to the second handle side bar 227b. The second coupler 312(2) of the straightener 300 may define at least one of the protrusions and openings, and the second coupler of the handle 226 may define the other of the protrusions and openings, which is configured to mate with the second coupler 312(2).

[0152] Figures 31 and 32 illustrate a particular example in which each of the first coupler 312(1) and the second coupler 312(2) of the organizer 300 defines a protrusion, and the coupler 229 of the car seat handle 226 defines an opening for receiving the protrusion. The first coupler 312(1) and the second coupler 312(2) are attached to the bracket 302; however, in an alternative example, the couplers may be attached to another component of the organizer 300. The protrusion of one of the couplers, such as the protrusion of the first coupler 312(1), may be positioned so that it does not retract into the organizer 300. Alternatively, the protrusion of the other of the couplers, such as the protrusion of the second coupler 312(2), may be configured to selectively extend out of the organizer 300 (Figure 32) and retract into the organizer 300 (Figure 33). In such instances, the protrusion of the second coupler 312(2) may be spring-biased to extend from the organizer 300. The organizer 300 may include an actuator 314 configured to be engaged by a caregiver to change the protrusion of the first coupler 312(1) between an extended position (FIG. 32) and a retracted position (FIG. 33).

[0153] Turning now to Figures 24 and 26 through 28, in some embodiments, the infant car seat 200 may be configured such that the organizer 300 can only be installed when the handle 226 is in the extended position. Alternatively, in some embodiments, the infant car seat 200 may be configured such that the handle 226 cannot be retracted when the organizer 300 is coupled to it. For example, the handle 226 of the infant car seat 200 may include at least one organizer latch 260 configured to switch between a blocked position (Figure 26) and an unblocked position (e.g., Figure 27), in which the organizer 300 is prevented from attaching to one or more couplers 229 of the car seat handle 226, and in the unblocked position, the organizer 300 is allowed to attach to one or more couplers 229 of the car seat handle 226.

[0154] Each organizer latch 260 may be implemented in one of the handle side levers 227a, 227b. In some instances, each handle side lever 227a, 227b may include organizer latch 260. Figures 26 and 27 show a particular example of organizer latch 260; however, it should be understood that organizer latch 260 may be implemented in any other suitable manner. Organizer latch 260 may define an opening 260a therein. Organizer latch 260 may be configured such that when organizer latch 260 is in the unblocked position (Figure 27), opening 260a of organizer latch 260 is substantially aligned with the opening defined by handle coupler 229. Thus, one of the couplers 312(1), 312(2) of organizer 300 may be received through opening 229 of handle 226 and received into opening 260a of organizer latch 260. This is illustrated in Figure 28. In some instances, the organizer latch 260 may be coupled to the link 258 of the handle extension actuator 252 such that when a caregiver actuates the handle extension actuator 252, the organizer latch 260 moves from the unlocked position (FIG. 27) to the blocking position (FIG. 26). Referring to FIG. 28, when the organizer 300 is attached to the car seat handle 226, one of the couplers 312(1) and 312(2) interferes with the movement of the organizer latch 260, thereby preventing the caregiver from actuating the handle extension actuator 252. Thus, when the organizer 300 is coupled to the handle 226, it prevents the handle 226 from moving from the extended position to the retracted position. Conversely, when the handle extension actuator 252 is actuated by the caregiver, the organizer latch 260 is in the blocking position, thereby preventing the installation of the organizer 300.

[0155] The infant car seat handle 226 can be configured such that when the infant car seat handle 226 is in the retracted position, each organizer coupler 229 of the handle 226 is covered by one of the first handle portion 226a and the second handle portion 226b. In other words, in the retracted position, each organizer coupler 229 can retract into one of the first handle portion 226a and the second handle portion 226b, so that the organizer 300 cannot be coupled to the organizer coupler 229.

[0156] Although Figures 24 and 26-28 show examples of each organizer coupler 229 of the infant car seat handle 226 defining an opening for a protrusion configured to receive a coupler 312(1), 312(2) of the organizer 300, the examples of this disclosure are not limited thereto. In an alternative example, each organizer coupler 229 of the infant car seat handle 226 may include a protrusion (not shown) extending inward from the handle 226, and each coupler 312(1), 312(2) of the organizer 300 includes an opening configured to receive a corresponding one of the protrusions. In some such examples, the protrusion of each organizer coupler 229 may be configured to retract into the handle 226 when the handle 226 is in the retracted position, thereby preventing the organizer 300 from attaching to the coupler 229. Furthermore, when the organizer 300 is attached to each organizer coupler 229 of the handle 226, each coupler 229 may interfere with one of the couplers 312(1) and 312(2) of the organizer 300, thereby preventing the other of the couplers 312(1) and 312(2) from retracting into the handle 226. It should be understood that the handle 226 described above can alternatively be implemented in child vehicles other than infant car seats, such as in toddler seats 400 or in cradles or portable cribs. Therefore, the above description is equally applicable to toddler seats 400 or cradles or portable cribs.

[0157] [Child seat with push handle]

[0158] Referring to Figures 36A to 37B, the travel system 10 is shown as a stroller 100 of Figures 3 and 4, and a removable child carrier 400 as a toddler seat. The toddler seat 400 includes a seat frame 402 and a push handle 404 attached to the seat frame 402. The seat frame 402 may be a tubular frame formed of one or more tubes. The seat frame 402 includes a first side rail 406 and a second side rail 408, which are spaced apart from each other in the lateral direction A to define an opening or space 410 in which the child is positioned when seated in the toddler seat. The toddler seat 400 may include a textile 416 disposed within the space 410, configured to provide a seat surface 416a and cushioning for the toddler. The textile 416 may define a seat base 416b and a seat back 416c. The textile 416 may define a pair of spaced-apart sidewalls 416d. The seat base 416b and seat back 416c can extend between the side walls 416d. In an alternative example (not shown), the toddler seat 400 may include a plastic body defining the seat surface 416a, including the seat base 416b and seat back 416c.

[0159] The first side rail 406 has a first rail end 406a and a second rail end 406b spaced apart from each other along a first direction D1. The first side rail 406 is elongated along the first direction D1. Similarly, the second side rail 408 has a first rail end 408a and a second rail end 408b spaced apart from each other along the first direction D1. The second side rail 408 is elongated along the first direction D1. The seat frame 402 may include a flat bottom rail 412 extending between the first side rail 406 and the second side rail 408. For example, the flat bottom rail 412 may extend from the second rail end 406b of the first side rail 406 to the second rail end 408b of the second side rail 408. The flat bottom rail 412 may extend along a second direction D2 perpendicular to the first direction D1. In some embodiments, the second direction D2 may be aligned with the lateral direction A. The flat bottom rail 412 is elongated along the second direction D2. Therefore, the first side rail 406, the second side rail 408, and the flat bottom rail 412 can together define a "U" shape. The first side rail 406, the second side rail 408, and the flat bottom rail 412 can be separate components coupled to each other, or they can be portions of a continuous tube that is bent to define the shape of the seat frame 402.

[0160] A push handle 404 is configured to be grasped by a caregiver to push the travel system 10 when the child seat 400 is attached to the stroller 100. For example, the push handle 404 may extend above the seat frame 402 for easy access by a caregiver. The child seat 400 is configured such that removing the child seat 400 from the stroller 100 will cause the handle 400 to be removed from the stroller 100 along with the child seat 400.

[0161] The push handle 404 can be configured to shift between an extended position and a retracted position. In some instances, the push handle 404 can be configured to shift to one or more intermediate positions between the extended and retracted positions. When in the extended position, the push handle 404 can extend further above the seat frame 402 compared to the retracted position. In one instance, the push handle 404 can be attached to the seat frame 402 such that the handle 404 is retractable relative to the seat frame 402. For example, the handle 404 may include a first handle portion 404a and a second handle portion 404b. The first handle portion 404a is retractable relative to a first side rail 406, and the second handle portion 404b is retractable relative to a second side rail 408. The first handle portion 404a and the second handle portion 404b may be offset from each other in a lateral direction A. The handle 404 may, if applicable, include a third handle portion 404c extending between the first handle portion 404a and the second handle portion 404b. In an alternative example (not shown), the push handle may be pivotally attached to the seat frame at a pivot point, such that the handle rotates toward and away from the seat frame along the pivot axis, which may extend along, for example, a second direction D2.

[0162] Referring to Figure 38, the child seat 400 may include at least one handle extension lock 420 configured to selectively lock the handle 404 in an extended and retracted position. At least one handle extension lock 420 is configured to selectively lock the handle 404 in a retracted and extended position. Each handle extension lock 420 may be implemented in one of a first handle portion 404a and a second handle portion 404b. The handle extension lock 420 may include a handle extension latch 422 configured to move between a locked position (Figure 38) and an unlocked position. In the locked position, the latch 422 prevents the handle 404 from changing between the extended and retracted positions. In the unlocked position, the handle 404 is allowed to change between the extended and retracted positions. For example, the handle extension latch 422 may define a protrusion 422a configured to move between the locked and unlocked positions. The handle extension latch 422 is movable along a direction offset at an angle (such as perpendicular to) the axis AH of the first handle portion 404a or the second handle portion 404b. In the locked position, the protrusion 422a of the handle extension latch 420 extends into an opening 409 in one of the first side rails 406 and the second side rail 408, such that the protrusion 422a prevents the handle 404 from extending. One of the first side rails 406 and the second side rail 408 may contain a plurality of openings 409 offset from each other along the axis AH, each opening corresponding to a different position of the handle 404. In the unlocked position, the protrusion 422a of the handle extension latch 422 is removed from the opening 409 in one of the first side rails 406 and the second side rail 408, thereby allowing the handle 404 to extend or retract.

[0163] The handle extension lock 420 may include a latch guide 424 configured to guide movement of the latch 420 between a locked position and an unlocked position. The latch guide 424 may be configured to translate along the selection direction DS along the axis AH of the handle 404. The latch guide 424 may include a guide surface that guides a corresponding surface of the latch 422. For example, the latch guide 424 may include a slot 424a offset at an angle to the selection direction DS, and the latch 422 may include a pin 422b received in the slot 424a. When the latch guide 424 moves upward along the selection direction DS, the pin 422b translates along the slot 424a, thereby displacing the protrusion 422a from an opening 409 in one of the first side rails 406 and the second side rail 408. When the latch guide 424 moves downward along the selection direction DS, the pin 422b translates along the slot 424a, thereby moving the protrusion 422a into one of the openings 409 of the first side rail 406 and the second side rail 408.

[0164] The toddler seat 400 may include a handle extension actuator 426 (labeled in FIG. 36A) configured to be engaged by a caregiver to move the handle extension lock 420 between a locked position and an unlocked position. The handle extension actuator 426 may be implemented in any suitable manner. The handle extension actuator 426 includes a movable body having an engagement surface configured to be engaged by a caregiver to actuate the handle extension actuator 426. In one example, the movable body defines a button that defines the engagement surface. The button can be actuated by pressing it into the handle 404.

[0165] Referring again to Figure 38, the handle extension actuator 426 may include a link 428, such as a wire, cable, or strap, extending from the movable body of the actuator 426 to the handle extension lock 420. The handle extension actuator 426 may be configured such that movement of the movable body by a caregiver causes a corresponding movement of the link 428, thereby shifting the handle actuated lock 420 between a locked and unlocked position. The handle extension actuator 426 may be configured to convert translational movement of the movable body of the actuator 426 into translational movement of the link 428 along axis AH. It should be understood that in other embodiments, the handle extension actuator 426 may be implemented in another suitable manner. For example, the handle extension actuator 426 may be implemented as a pull handle instead of a button, or as a sleeve that translates along a portion of the handle 404. The handle extension actuator 426 may also be implemented in positions other than those shown.

[0166] Referring back to Figures 36A to 37B, the child seat 400 can be configured to switch between an unfolded configuration (Figure 37A) and a folded configuration (Figure 37B). The frame 402 may include an upper frame end 402a and a lower frame end 402b, wherein when a child is seated in the child seat 400, the upper frame end 402a is positioned closer to the child's head and the lower frame end 402b is positioned closer to the child's feet. The child seat 400 is configured to switch from an unfolded configuration to a folded configuration by rotating the upper frame end 402a toward the lower frame end 402b, and from a folded configuration to an unfolded configuration by rotating the upper frame end 402a away from the lower frame end 402b. When in the folded configuration, the upper frame end 402a may be substantially parallel to the lower frame end 402b. The frame 402 may include a pair of folding hubs 418(1), 418(2) that allow the upper frame end 402a and the lower frame end 402b to be pivotally connected to each other. A first folding hub 418(1) can be attached to the first side rail 406 between the first rail end 406a and the second rail end 406b. Similarly, a second folding hub 418(2) can be attached to the second side rail 408 between the first rail end 408a and the second rail end 408b. The toddler seat 400 can be configured to remain fixed to the stroller 100 when the toddler seat is in a folded configuration and the stroller 100 is in a first folded configuration, as shown in FIG37B. As shown, when both the toddler seat 400 and the stroller 100 are folded, the couplers 116(1), 116(2) can rotate forward such that the upper end 402a of the frame of the toddler seat 400, the lower end 402b of the frame of the toddler seat 400, and the front support legs 108(1), 108(2) of the stroller 100 can be substantially parallel to each other.

[0167] Referring to Figures 39A to 39C, the child seat 400 may include at least one folding latch 430 configured to releasably lock the stroller 100 in an unfolded position. Each folding latch 430 may be disposed in one of folding hubs 418(1), 418(2). Each folding latch 430 may be implemented in any suitable manner. Figures 39A to 39C show an example of a first folding hub 418(1). A second folding hub 418(2) may be implemented in a similar manner. However, it should be understood that the folding hub 418(1) and the folding latch 430 may be implemented in another suitable manner. The child seat 400 may include a folding actuator 432 (labeled in Figure 36B) configured to actuate at least one folding latch 430 to move at least one folding latch 430 between an unlocked position and a locked position, in which the child seat 400 is allowed to fold and in the locked position, the child seat 400 is prevented from folding. Actuator 432 can be any suitable actuator.

[0168] Generally, each folding hub 418(1), 418(2) has a lower end plate 434 and an upper end plate 436 pivotally coupled to each other. The upper end plate 436 is positioned fixed to the upper end 402a of the seat frame 402 such that rotation of the upper end 402a causes a corresponding rotation of the upper end plate 436. The lower end plate 434 is positioned fixed to the lower end 402b of the seat frame 402 such that rotation of the lower end 402b causes a corresponding rotation of the lower end plate 434. The upper end plate 436 and the lower end plate 434 can be aligned with each other along the folding pivot axis AF. The folding latch 430 can be rotatably fixed relative to one of the upper end plate 436 and the lower end plate 434 and can be configured to releasably engage the other of the upper end plate 436 and the lower end plate 434 so that the upper end 402a and the lower end 402b of the frame are rotatably locked relative to each other.

[0169] For example, Figures 39A to 39C illustrate a particular example in which a folding latch 430 is rotatably secured relative to an upper end plate 436 and configured to releasably engage a lower end plate 434. The folding latch 430 is translatable relative to the upper end plate 436 along the axis of the upper end 402a. The lower end plate 434 defines a guide groove 434a and a plurality of recesses 434b, 434c extending from the guide groove 434a. The guide groove 434a may be curved to define an arc or a circle. Each recess 434b, 434c may correspond to a different folding configuration of the child seat 400. For example, the lower end plate 434 may define a first recess 434b corresponding to the unfolded configuration and a second recess 434c corresponding to the folded configuration. The folding latch 430 includes a protrusion 430a configured to translate along the guide groove 434a as the child seat 400 changes between the folded and unfolded configurations. The protrusion 430a extends through the linear slot 436a of the upper end plate 436 and into the guide groove 434a of the lower end plate 434 to translate along the linear slot 436a. The protrusion 430a is configured to be selectively received in recesses 434b and 434c to rotatably lock the upper end 402a and lower end 402b of the frame relative to each other in either an unfolded or folded configuration. Figure 39B shows the child seat 400 in an unfolded configuration, wherein the protrusion 430a of the folding latch 430 is received in a first recess 434b, and Figure 39C shows the child seat 400 in a folded configuration, wherein the protrusion 430a of the folding latch 430 is received in a second recess 434c.

[0170] The toddler seat 400 may include an armrest or child support 438, which can be configured to fold together with the seat frame 402. In one example, a folding hub can be configured to guide the armrest or child support 438 between an unfolded and folded configuration. For instance, the armrest or child support 438 may include a hub 440 having a protrusion 440a. A lower end plate 434 may have a first groove 434d that receives the protrusion 440a of the hub 440. The first groove 434d may be curved to define an arc or a circle. The first groove 434d may have an upper end 434e that, when the toddler seat 400 is in the unfolded configuration shown in FIG. 39B, restricts the upward movement of the protrusion 440a and thus restricts the upward movement of the armrest or support 438. The upper end plate 436 may have a second groove 436b that receives the protrusion 440a of the hub 440. The second groove 436b has a lower end 436c and an upper end 436d. When the child seat 400 is in the unfolded configuration shown in FIG39B, the lower end 436d restricts the downward movement of the protrusion 440a and thus restricts the downward movement of the arm or bracket 438. When the frame 402 is rotated to the folded configuration, the upper end plate 436 rotates downward, which causes the upper end 436d of the second groove 436b to rotate downward and engage the protrusion 440a of the hub 440 to drive the protrusion 440a downward and thus drive the arm or bracket 438 downward, as shown in FIG39C.

[0171] Referring back to Figures 36A to 37B, the toddler seat 400 is configured to be removably coupled to the stroller 100. The toddler seat 400 may include at least one coupler configured to removably couple the toddler seat 400 to the stroller 100. The at least one coupler may include a pair of couplers 414(1), 414(2). The first coupler 414(1) of the pair may be configured to be removably coupled to a first seat coupler 116(1) of the stroller 100. The first coupler 414(1) may be attached to the first side rail 406 between a first rail end 406a and a second rail end 406b. The second coupler 414(2) of the pair may be configured to be removably coupled to a second seat coupler 116(2) of the stroller 100. The second coupler 414(2) can be attached to the second side rail 408 between the first rail end 408a and the second rail end 408b.

[0172] Referring to Figures 40A to 42, in some embodiments, each of the first coupler 414(1) and the second coupler 414(2) of the child seat 400 may define a storage portion 442, which is configured to receive a latch 117 of a corresponding one of the first seat coupler 116(1) and the second seat coupler 116(2). It should be noted that, in alternative embodiments, the stroller 100 may include a storage portion, and the child seat 400 may include latches. Each storage portion 442 defines a recess 444, which is configured to receive at least a portion therein of a corresponding one of the latches 117, such as the upper portion of the latch 117. Each of the first coupler 414(1) and the second coupler 414(2) may define a protrusion or opening 446a, which is configured to engage the other of the protrusion and opening 118 (labeled in FIG. 5A) of the stroller 100. FIG. 40A to 42 show an example in which each of the first coupler 414(1) and the second coupler 414(2) defines a protrusion 446a, which is configured to be received in the opening 118 (labeled in FIG. 5A) of the stroller 100. Each protrusion 446a extends into a recess 444 of the other of the couplers 414(1) and 414(2). Each coupler 414(1), 414(2) can engage different lateral sides of the stroller 100 to restrict the movement of the toddler seat 400 relative to the stroller 100 along the lateral direction A, the vertical direction V and / or the longitudinal direction L.

[0173] In some instances, each coupler 414(1), 414(2) may include a movable latch 446 comprising a protrusion 446a. The movable latch 446 may be movable between a latched position (FIG. 41B) and an unlocked position (FIG. 41A). In the latched position, the protrusion 446a may extend into an opening 118 of a corresponding one of the seat couplers 116(1), 116(2) of the stroller 100. In the unlocked position, the protrusion 446a is removed from the opening 118.

[0174] Referring more specifically to Figures 41A to 42, the toddler seat 400 may include an actuator 450 for each coupler 414(1), 414(2), configured to be engaged by a caregiver to move a latch 446 between a latched position and an unlocked position. Each actuator 450 may be any suitable actuator. Each actuator 450 may define an actuating surface 452, such as a button, configured to be pressed into a corresponding one of the folding hubs 418(1), 418(2). In an alternative example (not shown), each actuating surface 452 may define a pull handle. Each actuator 450 may include at least one link 454 that operatively couples the engaging surface 452 to the movable latch 446. In one example, at least one link 454 may include at least one ramp surface 454a, such as a pair of ramp surfaces 454a, which engage at least one engaging surface 446b of a corresponding latch 446, such that at least one engaging surface 446b travels along at least one ramp surface 454a, thereby pivoting the latch 446 between a latched position and an unlocked position.

[0175] Referring back to Figures 40A and 40B, in some instances, the toddler seat 400 may include at least one additional coupler 456, such as a pair of additional couplers 456, positioned in front of or behind a pair of couplers 414(1), 414(2). The pair of additional couplers 456 may be offset from each other in the lateral direction A. Each of the at least one additional coupler 456 may be attached to one of the first side rails 406 and the second side rails 408. Each of the at least one additional coupler 456 may be configured to be removably coupled to one of at least one of the additional couplers 132(1) or 132(2) (labeled in Figure 3) of the stroller 100. Each of at least one other coupler 456 couples the child seat 400 to the stroller 100 in order to limit the torque applied to a pair of couplers 414(1), 414(2) when a force is applied to the handle 404 of the child seat 400 (see FIG. 36).

[0176] In some instances, each of at least one other coupler 456 may include a movable latch 458 configured to move between a latched configuration (FIG. 40B) and an unlocked configuration (FIG. 40A). For example, each movable latch 458 may define a latch configured to pivot between the latched and unlocked configurations. Each movable latch 458 may be configured to be actuated by an actuator 450. The actuator 450 may be any suitable actuator. In some instances, each movable latch 458 may be actuated by an actuator 450 that also actuates one of the latches 446. Each actuator 450 may include a link 460 that operatively couples one of the latches 446 to a corresponding one of the actuation surfaces 452. Each link 460 may extend at least partially within one of the first side rail 406 and the second side rail 408. Actuation of actuator 450 causes translation of link 460, thereby pivoting latch 458 between latched configuration (Fig. 40B) and unlocked configuration (Fig. 40A). Latch 458 can be biased to latched configuration.
