Background Art

[0003] Baby strollers are generally used to transport young children, such as by pushing a young child who is sitting in an infant car seat when the infant car seat is removed from a vehicle. Most baby strollers include a foldable frame so that they can be stored in a car trunk or other storage location. For some time, reducing the folded size of baby strollers has been a goal of the juvenile product industry. Improvements have been made in this field, but the desire to reduce the folded size of baby strollers in this industry still remains.

Summary of the Invention

[0004] In one example, a child carrier is configured to be detachably coupled to a child carriage for pushing the child carrier. The child carrier comprises a frame or body, a handle coupled to the frame or body, and a handle rotation lock. The frame or body defines an opening configured to support a child inside. The handle is configured to move between an extended position and a retracted position relative to the frame or body, and to rotate relative to the frame or body between a number of rotation positions. The handle rotation lock has a rotation latch configured to move along the axis of the handle between an unlocked position and a locked position in order to selectively lock the handle in each of the rotation positions.

[0005] In other examples, a child carrier is configured to be detachably coupled to a child carriage for pushing. The child carrier comprises a frame or body, a handle, a handle extension lock, and a handle extension stop. The frame or body defines an opening configured to support a child inside. The handle is coupled to the frame or body by a handle hub so that the handle is configured to rotate relative to the frame or body between several rotational positions. The handle is also configured to move between an extended position and a retracted position relative to the frame or body. The handle extension lock is configured to move between a locked position and an unlocked position to selectively lock the handle in the retracted and extended positions. The handle extension stop is located within the handle hub and is configured to move between 1) a block position that prevents the handle from moving from the retracted position to the extended position regardless of the position of the handle extension lock, and 2) a release position that allows the handle to move from the retracted position to the extended position while the handle extension lock is in the unlocked position.

[0006] In yet another example, the mobility system comprises a child carriage and a child carrier. The child carriage comprises a frame and a number of wheels. The frame has an upper end and a lower end, and the wheels are attached to the lower end. The child carrier is configured to be detachably coupled to the upper end. The child carrier comprises a frame or body, a handle coupled to the frame or body, a handle rotation lock, and a handle rotation stop. The frame or body defines an opening configured to support a child inside. The handle is configured to move between an extended position and a retracted position relative to the frame or body, and to rotate relative to the frame or body between a number of rotation positions. The handle rotation lock is configured to move between an unlocked position and a locked position to selectively lock the handle in each of the rotation positions. The handle rotation stop is configured to move between (1) a blocking position that prevents the handle from rotating from one rotation position to another, regardless of the position of the handle rotation lock, and (2) a release position that allows the handle to rotate from one rotation position to another while the handle rotation lock is in the unlocked position. The carriage does not have any push handles extending above the child carrier, and the handles of the child carrier are configured to push the child carriage when the child carrier is coupled to the child carriage.

[0007] In yet another example, the mobility system comprises a child carriage and a child carrier. The child carriage comprises a frame and a number of wheels. The frame has an upper end and a lower end, and the wheels are attached to the lower end. The child carrier is configured to be detachably coupled to the upper end. The child carrier comprises a frame or body, a handle coupled to the frame or body, a handle extension lock, and a handle extension stop. The frame or body defines an opening configured to support a child inside. The handle is configured to move between an extended position and a retracted position relative to the frame or body, and to rotate relative to the frame or body between a number of rotational positions. The handle extension lock is configured to move between a locked position and an unlocked position to selectively lock the handle in the retracted and extended positions. The handle extension stop is configured to move between 1) a block position that prevents the handle from moving from the retracted position to the extended position regardless of the position of the handle extension lock, and 2) a release position that allows the handle to move from the retracted position to the extended position while the handle extension lock is in the unlocked position. The carriage does not have any push handles extending above the child carrier, and the handles of the child carrier are configured to push the child carriage when the child carrier is coupled to the child carriage.

[Modes for carrying out the invention]

[0010] Figures 1 and 2 show an example of the mobility system 10 comprising a child carriage 100 and at least one detachable child carrier. Generally, this at least one detachable 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 bassinet (not shown), or a carrycot (not shown). In some examples, the mobility system 10 may comprise an infant car seat 200, a toddler seat 400, a bassinet, or a carrycot, or any combination thereof. The child carriage 100 comprises a frame 102 configured to support a child carrier (e.g., 200, 400) above the riding surface, and a plurality of wheels 104 attached to the frame 102 and configured to move the child carriage 100 and the child carrier (e.g., 200, 400) along the riding surface. The child carrier (e.g., 200, 400) and the child carriage 100 are configured to be detachably coupled to each other. When not in use, the child carriage 100 can be compactly folded for storage in a vehicle, an aircraft overhead storage compartment, or other location. As will be discussed in more detail below, the child carriage 100 may be configured to fold from an extended configuration to a first folded configuration (e.g., Figures 8A-8C), and optionally to fold from the first folded configuration to a second folded configuration (e.g., Figures 9A, 9B), in which case the child carriage 100 occupies a smaller volume in the second folded configuration than in the first folded configuration.

[0011] Unlike conventional strollers, the Child Carriage 100 does not have a push handle used to push a child. In other words, the Child Carriage 100 does not have a handle extending above the child carrier that is accessible to an adult for pushing the Child Carriage 100 while the adult is standing upright. Rather, the child carriers (e.g., 200, 400) have handles (e.g., 226 in Figure 10, 404 in Figure 36A) that can be used by a caregiver to push the Child Carriage 100 and the child carrier (e.g., 200, 400) along the riding surface when the child carrier (e.g., 200, 400) is coupled to the Child Carriage 100. In some examples, when the child carrier (e.g., 200) is detached from the Child Carriage 100, the same handle (e.g., 226) can be used to carry the child carrier (e.g., 200). The child carrier (e.g., 200, 400) is configured such that when the child carrier (e.g., 200, 400) is removed from the child carriage 100, the handle (e.g., 226, 404) is removed from the child carrier (e.g., 200, 400) along with the child carrier (e.g., 200, 400). As a result, the child carriage 100 can achieve a more compact folded volume compared to conventional strollers with comparable push handles. In some examples, the mobility system 10 may include a mobility organizer 300 which can be configured to hold at least one item, such as a drink container for the caregiver, a portable device, or other item. The mobility organizer 300 may be configured to be detachably coupled to the handle (e.g., 226, 404) of the child carrier (e.g., 200, 400).

[0012] Child carriage Referring more specifically to Figures 2 to 4, the frame 102 of the child carriage 100 has an upper end 102a and a lower end 102b that are offset from each other along the vertical direction V. The frame 102 has a front end 102c and a rear end 102d that are offset from each other along the longitudinal direction L which is perpendicular to the vertical direction V. The frame has a first side 102e and a second side 102f that are offset from each other along the lateral direction A which is perpendicular to both the vertical direction V and the longitudinal direction L.

[0013] The child carriage 100 comprises a plurality of wheels 104 positioned on the lower end 102b of the frame 102. The upper end 102a of the frame 102 is configured to be detachably coupled to the child carriers (e.g., 200, 400) such that the child carriers (e.g., 200, 400) are spaced apart above the riding surface. As will be described in more detail below, the upper end 102a of the frame 102 comprises at least one seat coupling portion that detachably couples the child carriers (e.g., 200, 400) to the child carriage 100, thereby limiting the movement of the child carriers (e.g., 200, 400) relative to the child carriage 100 along at least one of the vertical direction V, the longitudinal direction L, and the lateral direction A. In some examples, at least one seat coupling is configured to detachably connect the child carrier (e.g., 200, 400) to the child carriage 100, thereby restricting the movement of the child carrier (e.g., 200, 400) relative to the child carriage 100 along at least two of the vertical V, longitudinal L, and lateral A directions, for example, all three of the vertical V, longitudinal L, and lateral A directions. For example, at least one seat coupling may be configured to detachably connect the child carrier (e.g., 200, 400) to the carriage 100 so as to prevent detachment along the upward direction of the child carrier (e.g., 200, 400). At least one seat joint may be configured to be detachably coupled to a rigid part of the child carrier (e.g., 200, 400), such as a rigid body (e.g., 202 in Figure 10), or the shell of the child carrier (e.g., 200), or the rigid frame of the child carrier (e.g., 400) (e.g., 402 in Figure 36A).

[0014] The frame 102 may comprise at least one leg assembly 106(1) and a second leg assembly 106(2) offset from each other along the 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 comprise 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. The first leg assembly 106(1) may comprise a first hinge 112(1) that rotatably connects the first front leg 108(1) and the first rear leg 110(1) relative to each other. For example, the first hinge 112(1) can pivotably connect 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) can define a pivot axis AP1 extending along the lateral direction A. The first front leg 108(1) and the first rear leg 110(1) can be configured to pivot around the pivot axis AP1 so that the lower ends of the first front leg 108(1) and the first rear leg 110(1) move toward each other along the longitudinal direction L until a first folded configuration, and then move apart from each other along the longitudinal direction L until an extended configuration.

[0015] The second leg assembly 106(2) may comprise 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 comprise a second hinge 112(2) that pivotably connects the second front leg 108(2) and the second rear leg 110(2) relative to each other. For example, the second hinge 112(2) may pivotably connect 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 third rear leg 110(2) may be configured to rotate around a pivot axis AP1 so that the lower ends of the second front leg 108(2) and the second rear leg 110(2) move toward each other along the longitudinal direction L until a first folded configuration is reached, and move apart from each other along the longitudinal direction L until an extended configuration is reached.

[0016] The frame 102 may include at least one cross piece 114(1), 114(2) extending between the first and second leg assemblies 106(1) and 106(2) to cause the first and second leg assemblies 106(1) and 106(2) to be separated from each other along the lateral direction A. Each cross piece may be in the shape of a bar, a tube, or any other preferred shape. The at least one cross piece 114(1), 114(2) may include a first cross piece 114(1) extending from the first leg 108(1) to the front leg 108(2). The first cross piece 114(1) may have a first end attached to the first front leg 108(1) and a second end attached to the second front leg 108(2). At least one cross piece 114(1), 114(2) may include a second cross piece 114(2) extending from a first rear leg 110(1) to a second rear leg 110(2). The second cross piece 114(2) may have a first end attached to the first rear leg 110(2) and a second end attached to the second rear leg 110(2). In some examples, the frame 102 may include a third cross piece 114(3) extending between the first and second leg assemblies 106(1) and 106(2). The third cross piece 114(2) may be positioned higher than the first and second cross pieces 114(1) and 114(2) with respect to the vertical direction V. A third cross piece 114(2) may be positioned between the first and second cross pieces 114(1) and 114(2) with respect to the longitudinal direction L when the carriage 100 is in an extended configuration. A third cross piece 114(3) may define a carry handle 122. The carry handle 122 may be configured to allow the child carriage 100 to be carried by hand when the child carrier (e.g., 200, 400) is detached from the child carriage 100.

[0017] The multiple wheels 104 may include at least three wheels 104, and in some examples, four wheels 104. For example, the multiple wheels 104 may include a first pair of wheels 104 positioned 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 leg 110(1) of the first leg assembly 106(1), and the second wheel 104 of the first pair may be coupled to the lower end of the second rear leg 110(2) of the second leg assembly 106(2). The multiple wheels 104 may include at least one wheel 104 positioned at the front end 102e of the frame 102. For example, the multiple wheels 104 may include a second pair of wheels 104 positioned 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 leg 108(1) of the first leg assembly 106(1), and the second wheel 104 of the second pair may be coupled to the lower end of the second front leg 108(2) of the second leg assembly 106(2). Alternatively, the group of wheels may include a single wheel 104 (not shown) positioned 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 first legs 108(1) and 108(2), or the frame 102 may have a single front leg to which the wheel 104 is attached.

[0018] As discussed above, the child carriage 100 may have at least one coupling configured to connect a child carrier (e.g., 200, 400) to the child carriage 100. Figures 2 to 4 show one specific example of a coupling that may be used to connect a child carrier (e.g., 200, 400) to the child carriage 100, but it will be understood that the child carrier (e.g., 200, 400) may be connected to the child carriage 100 using other suitable couplings. In some examples, as shown in Figures 2 to 4, the at least one coupling may include a first pair of couplings 116(1), 116(2). The first coupling 116(1) of the first pair may be located on the first side 102e of the frame 102. The first coupling 116(1) may be attached to the first leg assembly 106(1). The first coupling portion 116(1) may be configured to couple to a first lateral side (e.g., 202e in Figures 10 and 11) of a child carrier (e.g., 200, 400). The second coupling portion 116(2) of the first pair may be positioned on a second side 102f of the frame 102. The second coupling portion 116(2) may be configured to couple to a second lateral side (e.g., 202f in Figures 10 and 11). The second coupling portion 116(2) may be attached to a second leg assembly 106(2). In some examples, each of the first and second coupling portions 116(1) and 116(2) may define a bayonet 117 as shown, but embodiments of the present disclosure are not limited thereto.

[0019] Each bayonet 117 may be an upward-extending projection. Each bayonet 117 may have an elongated length along a substantially 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 width. In some examples, the width may be greater than the thickness.

[0020] Each of the first and second couplings 116(1) and 116(2) may define a projection or opening 118 configured to engage with the other of a projection and opening (e.g., 216 in Figures 10 and 11, and 446 in Figures 40A and 40B) of a child carrier (e.g., 200, 400). Figures 2 to 4 show an example in which each coupling 116(1) and 116(2) defines an opening 118 on its inner surface configured to receive a projection (e.g., 216 in Figures 10 and 11) of a child carrier (e.g., 200, 400). Each coupling 116(1) and 116(2) may engage with different lateral sides of the child carrier (e.g., 200, 400) to restrict the movement of the child carrier along the lateral direction A. The projections or recesses 118 of each joint 116(1), 116(2) may be configured to engage with the projections and openings (e.g., 216 in Figures 10 and 11) of the child carrier (e.g., 200, 400) to restrict the movement of the child carrier along the vertical direction V (e.g., at least one of the upward and downward directions) and / or the longitudinal direction L.

[0021] At least one coupling may include at least one other coupling, such as a pair of infant car seat couplings 120(1), 120(2) configured to be detachably coupled to the infant car seat 200. At least one infant car seat coupling 120(1), 120(2) may be configured to engage with a movable latch 220 (see Figure 10) of the infant car seat 200, which secures the infant car seat 200 to the car seat base 500 (see Figures 13A, 13B). Each of the at least one infant car seat coupling 120(1), 120(2) may have an engagement surface configured to engage with the movable latch 220 of the infant car seat 200 in order to restrict the movement of the infant car seat along at least one of the vertical direction V and the longitudinal direction L.

[0022] Each of at least one infant car seat coupling portion 120(1), 120(2) may be offset from the first pair of coupling portions 116(1), 116(2) along the longitudinal direction L. For example, each of at least one infant car seat coupling portion 120(1), 120(2) may be positioned in front of or behind the first pair of coupling portions 116(1), 116(2) with respect to the longitudinal direction L. At least one infant car seat coupling portion 120(1), 120(2) connects the infant car seat 200 to the carriage 100 in such a way that the torque applied to the pair of seat coupling portions 116(1), 116(2) is limited when force is applied to the handle 226 of the infant car seat 200 (see Figure 10). In Figures 2 to 4, each infant car seat 120(1), 120(2) includes a cylindrical pin having an outer curved surface that defines an engagement surface. Each cylindrical pin may be oriented such that its central axis extends along the lateral direction A. In alternative examples, it is understood that each engagement surface may be defined by a shape other than a cylindrical pin, or that the cylindrical pin may be oriented in a different manner.

[0023] At least one coupling may comprise at least one infant seat coupling 132(1), 132(2) configured to be detachably coupled to the infant seat 400. At least one infant seat coupling 132(1), 132(2) may be identical to at least one infant car seat coupling 120(1), 120(2), or may be another coupling spaced apart from at least one infant car seat coupling 120(1), 120(2). In some examples, at least one coupling may comprise a pair of infant seat couplings 132(1), 132(2), each configured to be detachably coupled to the infant seat 400. At least one infant seat coupling 132(1), 132(2) may be configured to engage with a movable latch 456 of the infant seat 400 (see Figures 40A and 40B). Each of at least one infant seat attachment 132(1), 132(2) may have an engagement surface configured to engage with a movable latch 456 of the infant seat 400 so as to limit the movement of the infant seat 400 along at least one of the vertical direction V and the longitudinal direction L. Each of at least one infant seat attachment 132(1), 132(2) may be offset from the first pair of attachments 116(1), 116(2) along the longitudinal direction L. For example, each of at least one infant seat attachment 132(1), 132(2) may be positioned in front of or behind the first pair of attachments 116(1), 116(2) with respect to the longitudinal direction L. In one example, each infant car seat coupling 120(1), 120(2) may be positioned behind the first pair of couplings 120(1), 120(2), and each infant seat coupling 132(1), 132(2) may be positioned in front of the first pair of couplings 116(1), 116(2). At least one infant seat coupling 132(1), 132(2) connects the infant seat 400 to the carriage 100 in such a way that when force is applied to the handle 404 of the infant seat 400 (see Figure 36A), the torque applied to the pair of seat couplings 116(1), 116(2) is limited.

[0024] The child carriage 100 may include at least one folding latch (e.g., 125 in Figures 6A and 7B, described in more detail below) configured to lock the child carriage 100 in a releaseable position when it is extended. The child carriage 100 may include an actuator (e.g., 127 in Figure 6A, described in more detail below) configured to actuate at least one folding latch so as to move the at least one folding latch between an unlocked position in which the child carriage 100 is permitted to be folded and a locked position in which the child carriage 100 is not permitted to be folded. The actuator may include a third cross piece 114(3) defining a handle 122 that is grasped by a caregiver and configured to move at least one lock to the unlocked position. In some examples, the handle 122 may extend between the first and second leg assemblies 106(1) and 106(2). For example, the handle 122 may have an elongated length along the lateral direction A. In the examples shown in Figures 2 to 4, the handle 122 has a bar-like shape. However, it is understood that the handle 122 may have other preferred shapes in other examples. For example, the handle 122 may instead comprise a woven webbing or cord (not shown) extending between the first and second leg assemblies 106(1) and 106(2), the webbing or cord releasing the folding latch when the webbing or cord is pulled.

[0025] In some examples, the handle 122 may include a movable actuator body (e.g., 129 in Figure 6A, discussed below) such as a movable button, which is engaged by a caregiver and configured to move at least one lock (e.g., 125 in Figures 6A to 7B) to an unlocked position when the movable actuator body is moved (e.g., when a movable button is pressed down). The child carriage 100 may be configured so that the carriage 100 can be moved from an extended configuration to a first folded configuration by pulling the actuating handle 122 upward along the perpendicular direction. In some examples, this may be done after moving the movable actuator body. In other embodiments (e.g., when the handle includes webbing or a cord), movement of the actuator handle 122 itself can move at least one lock from a locked position to an unlocked position, and then further movement of the actuator handle 122 can move the child carriage 100 from an extended configuration to a first folded configuration.

[0026] The child carriage 100 may have at least one coupling portion 124(1), 124(2). Figures 3 and 4 show an example in which the child carriage 100 comprises a first coupling portion 124(1) attached to a first side 102e of the frame 102 and a second coupling portion 124(2) attached to a second side 102f of the frame 102. In some examples, each coupling portion 124(1), 124(2) may be configured to drive one of the front legs 108(1), 108(2) and one of the rear legs 110(1), 110(2) toward each other when the child carriage 100 is moved to a first folded configuration, and toward each other when the first carriage 100 is moved toward an extended configuration. Each of at least one coupling section 124(1), 124(2) may include at least one seat coupling section. For example, each of at least one coupling section 124(1), 124(2) may include one of the infant car seat coupling sections 120(1), 120(2) and / or one of the infant seat coupling sections 132(1), 132(2). In some examples, each of at least one coupling section 124(1), 124(2) may include a support surface configured to support a child carrier (e.g., 200, 400) on it. Each of at least one coupling section 124(1), 124(2) may include a folding lock 125 (described in further detail below) which, when the folding lock 125 is in the locked position, restricts the movement of the coupling section, thereby preventing the child carriage 100 from transitioning from an extended configuration to a first folded configuration.

[0027] Referring specifically to Figures 5A to 5C, each connecting section 124(1) and 124(2) may comprise a first link 124a and a second link 124b. The first and second links 124a and 124b may have inner ends that are pivotably connected to each other at a first hinge 124c. The first link 124a may be further pivotably connected to one of the front legs 108(1) and 108(2), and the second link 124b may be further pivotably connected to one of the rear legs 110(1) and 110(2). The first and second links 124a and 124b of each connecting section 124(1) and 124(2) may each have a bar or plate-like shape, or any other preferred shape. The first and second links 124a and 124b of each connecting section 124(1) and 124(2) may define corresponding support surfaces 124c and 124d that are aligned with each other when the child carriage 100 is in an extended configuration. The support surfaces 124c and 124d may support the bottom surface of the child carrier (e.g., 200) when the child carrier (e.g., 200) is coupled to the frame 102 such that its bottom surface rests on the support surfaces 124c and 124d. This prevents the child carrier from moving downward relative to the frame 102.

[0028] The third cross piece 114(3) can be coupled to at least one linkage. For example, the third cross piece 114(3) can be coupled to the first linkage 124(1), such as one of the first and second links 124a and 124b of the first linkage 124(1). The third cross piece 114(3) can also be coupled to the second linkage 124(2), such as one of the first and second links 124a and 124b of the second linkage. The third cross piece 114(3) is configured such that when the third cross piece 114(3) is moved upward relative to the first and second leg assemblies 106(1) and 106(2), the inner ends of the first and second links 124a and 124b of each linkage 124(1) and 124(2) pivot relative to each other and move upward. This, in turn, moves the outer ends of the first and second links 124a and 124b of each connecting section 124(1) and 124(2) toward each other, thereby pulling the front legs 108(1) and 108(2) and the rear legs 110(1) and 110(2) toward the first folding configuration. Furthermore, each of the connectors 120(1) and 120(2) retracts as the front and rear legs move toward each other. Thus, it can be said that the child carriage 100 has at least one connecting section that retracts at least one connector when the child carriage 100 is transitioned to the first folding configuration.

[0029] Conversely, when the third cross piece 114(3) is moved downward relative to the first and second leg assemblies 106(1) and 106(2), the first and second links 124a and 124b of each connecting section 124(1) and 124(2) pivot relative to each other and move downward. This, in turn, moves the outer ends of the first and second links 124a and 124b of each connecting section 124(1) and 124(2) apart from each other, thereby moving the front end 108(1) and 108(2) and the rear end 110(1) and 110(2) apart from each other into an extended configuration. Furthermore, each of the connectors 120(1) and 120(2) extends as the front and rear legs move apart from each other. Therefore, it can be said that the child carriage 100 has at least one coupling that extends at least one connector when the child carriage 100 transitions to an extended configuration. In an alternative example, it is understood that the third cross piece 114(3) does not need to be coupled to at least one coupling. For example, the third cross piece 114(3) may, as an alternative, be coupled to one of the carriage legs 108(1), 108(2), 110(1), 110(2), or hinges 112(1), 112(2).

[0030] Continuing to refer to Figures 5A to 5C, each coupling 116(1), 116(2) may be configured to be positionable and fixed to the corresponding one of the leg assemblies 106(1), 106(2) when the carriage 100 is in the extended configuration, and to prevent the coupling 116(1), 116(2) from rotating relative to the leg assemblies 106(1), 106(2). In some examples, each coupling 116(1), 116(2) may be allowed to rotate when the carriage 100 is transitioned to the first folded configuration. For example, each coupling 116(1), 116(2) may be configured to rotate forward toward the front end of the carriage 100 when the carriage 100 is transitioned to the first folded configuration, as will be further discussed below with respect to Figures 37A and 37B, so that the infant seat 400 can remain attached to the carriage 100. The carriage 100 may have at least one stop for each coupling 116(1), 116(2) configured to restrict the rotation of the couplings 116(1), 116(2) when the carriage 100 is in an extended configuration, and to allow rotation when the carriage is in a first folded configuration. For example, the carriage 100 may have a stop 119 for each coupling 116(1), 116(2) configured to engage with the couplings 116(1), 116(2) in order to restrict the downward rotation of the couplings 116(1), 116(2) toward the rear end 102d of the carriage frame 102 when the carriage 100 is in an extended configuration. Each stop 119 may be attached to one of the rear legs 110(1), 110(2).

[0031] Each coupling 116(1), 116(2) may have at least one rotatable stop, such as a pair of rotatable stops 116a and 116b. Each rotatable stop 116a, 116b may engage with different sides of one leg tube 108a of the front legs 108(1), 108(2). Each coupling 116(1), 116(2) may have a rotatable hub 116c attached to the bayonet 117 of the coupling 116(1), 116(2), which has at least one rotatable stop 116a, 116b. The rotatable hub 116 may be rotatably fixed to the bayonet 117 such that the rotation of the rotatable hub 116 causes the bayonet 117 to rotate. When the carriage 100 is in an extended configuration (Figure 5A), at least one rotation stop 116a, 116b may be positioned so that the rotation hub 116, and consequently at least one rotation stop 116a, 116b, and the bayonet 117 do not rotate forward toward the front end 102c of the carriage frame 102.

[0032] When the carriage 100 is in the first folded configuration (Figure 5B), the leg tube 108a rotates, causing the swivel hub 116 and, consequently, at least one swivel stop 116a, 116b, and bayonet 117 to rotate forward as shown in Figure 5B. At least one stop 116a, 116b engages with the leg tube 108a to limit further forward rotation of the swivel hub 116, at least one stop 116a, 116b, and bayonet 117. When the carriage is in the first folded configuration in Figure 5B, at least one rotatable stop 116a, 116b may be positioned to allow downward rotation of the coupling 116(1), 116(2) toward the rear end 102d of the carriage frame 102.

[0033] Returning to Figures 6A to 7B, the child carriage 100 may be provided with a folding latch 125 for each of the first and second connecting portions 124(1) and 124(2). Each folding latch 125 can prevent the links of each of the connecting portions 124(1) and 124(2), such as the first and second links 124a and 124b, from pivoting relative to each other. Each folding latch 125 may be provided with a movable projection 125a configured to move between a locked position and an unlocked position. In the locked position, the projection 125a can engage with at least one of the first and second links 124a and 124b so that the first and second links 124a do not pivot relative to each other around the hinge 124c. At least one of the first and second links 124a and 124b may be provided with an engagement surface 124e configured to engage with the projection 125a. In the unlocked position, projection 125a can be retracted so that projection 125a is disengaged from at least one of the first and second links 124a and 124b, allowing the first and second links 124a to pivot relative to each other around the hinge 124c. In some examples, projection 125a can rotate between the locked and unlocked positions, as shown in Figures 7A and 7B.

[0034] Each folding latch 125 may include a latch housing 125b configured to accommodate a projection 125a. In Figures 6A and 6B, a portion of link 124b is cut out to expose the latch housing 125b. Each latch housing 125b can be pivotably connected to a third cross piece 114(3) around the pivot axis AP2 or AP3, respectively, to the first and second links 124a and 124b. The carriage 100 may be configured to fold around the pivot axis AP2 or AP3 to transition to a second folding configuration (Figure 6C). When the carriage 100 is in the extended configuration (Figure 6A), the first folding configuration (Figure 6B), and the second folding configuration (Figure 6C), each latch housing 125b may be configured to be at least partially located within the respective links of the connecting portions 124(1) and 124(2). In this way, each latch housing 125b can occupy the space S between the end 114a of the third cross piece 114(3) and the first and second connecting portions 124(1) and 124(2), respectively, so as to avoid any potential pinching points that would otherwise exist in space S without the housing latch 125b.

[0035] Briefly returning to Figures 7A and 7B, the actuator 127 may comprise a movable actuator body 129 configured to be engaged by a caregiver to move a folding latch 125 between an unlocked position and a locked position. The movable actuator body 129 can be moved relative to a handle 122. In one example, the movable actuator body 129 may be carried by the handle 122. For example, the movable actuator body 129 may define a button configured to retract into the handle 122 when pushed by a caregiver. The actuator 127 may comprise a link 131, such as a band, wire, or cable, attached to the movable actuator body 129 and the folding latch 125, such that the movement of the movable actuator body 129 is translated into the movement of the folding latch 125 between an unlocked position and an unlocked position. For example, the actuator body 129 may have an inclined surface 129a that engages with the inclined surface of the link 131 so as the actuator body 129 is moved along a direction angularly offset from the lateral direction A (e.g., vertical or longitudinal direction), the link 131 is translated along the lateral direction. The movement of the link 131 can rotate the latch projection 125a around the pivot 125c between a locked position and an unlocked position. The latch 125 and actuator 127 may be implemented in other preferred forms.

[0036] In alternative examples, at least one connecting part may be configured in a manner other than shown. For example, in some examples, at least one connecting part may not define a support surface. In some examples, at least one connecting part may not support either connector 120(1) or 120(2). In some examples, at least one connecting part may have more than two links, and / or the links may be configured in a manner other than shown. In some examples, at least one connecting part may not engage with 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) (Figure 3).

[0037] Returning to Figures 8A to 9B, the child carriage 100 can be folded from an extended configuration to a first folded configuration (Figures 8A to 8C) by rotating the front legs 108(1) and 108(2) relative to the rear legs 110(1) and 110(2) around a first pivot axis AP1 extending along the lateral direction A. In some examples, the child carriage 100 can be folded from the first folded configuration (Figures 8A to 8C) to a second folded configuration (Figures 9A and 9B) around at least one other pivot axis, such as pivot axes AP2 and AP3, which are angularly offset from the first pivot axis AP1. For example, at least one other pivot axis AP2 or AP3 can extend substantially along the vertical direction V. The child carriage 100 can be folded from a first folded configuration (Figures 8A-8C) to a second folded configuration (Figures 9A, 9B) by rotating the first and second leg assemblies 106(1) and 106(2) toward each other around at least one other pivot axis.

[0038] Each cross piece 114(1), 114(2), 114(3) may have at least one hinge, such as a first hinge 114d and a second hinge 114e, offset from each other along the length of the cross piece (for example, along the lateral direction A). The child carriage 100 is configured such that when the frame 102 moves into a first folding configuration, the first hinges 114b of the cross pieces 114(1), 114(2), 114(3) are aligned with each other along a second pivot axis AP2, and the second hinges 114b of the cross pieces 114(1), 114(2), 114(3) are aligned with each other along a third AP3. This arrangement allows the first leg assembly 106(1) to rotate toward the second leg assembly 106(2) about the second pivot axis AP2, and allows the second leg assembly 106(2) to rotate toward the first leg assembly 106(1) about the third pivot axis AP3.

[0039] As can be seen in Figures 1 and 2, the child carriage 100 does not have push bars and push handles extending upward from the leg assemblies 106(1) and 106(2) above the child carrier (200, 400) when the child carrier is coupled to the child carriage 100. Furthermore, as can be seen in Figures 3 and 4, the child carriage 100 does not have any frame structure extending upward from the leg assemblies 106(1) and 106(2) to support the fabric sheet. In fact, the child carriage 100 can be configured such that no part of the child carriage 100 extends above the child carrier (200, 400) when the child carrier (200, 400) is coupled to the child carriage 100.

[0040] Child Carriage Basket Referring to Figures 43 to 45, a child carriage 100 with a basket 126 according to one example is shown. The basket 126 may be formed from at least one fabric. The basket 126 may be positioned between first and second leg assemblies 106(1) and 106(2). The basket 126 may have a front end 126a and a rear end 126b offset from each other along the longitudinal direction L. The front end 126a and the rear end 126b may be substantially closed. The basket 126 may have a first side 126c and a second side 126d offset from each other along the transverse direction A. The first side 126c may be attached to the first leg assembly 106(1), and the second side 126c may be attached to the second leg assembly 106(2). The first and second sides 126c and 126d may extend from the front end 126a to the rear end 126b. The first and second sides 126c and 126d may be substantially closed. The front end 126a and rear end 126b may extend from the first side 126c to the second side 126d.

[0041] The basket 126 may have an upper end 126e and a lower end 126f that are offset from each other along the vertical direction V. The upper end 126e and the lower end 126f may extend from the upper end 126a to the rear end 126b, and from the first side 126e to the second side 126d. At least part to all of the upper end 126e may be open. The lower end 126e may be closed to prevent items stored inside from falling out of the basket 126. The basket 126 may have internal recesses 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.

[0042] The basket 126 may be attached to the first and second front legs 108(1) and 108(2) and to the first and second rear legs 110(1) and 110(2). The rear end 126b of the basket 126 may extend along the longitudinal direction L beyond at least a portion of each of the first and second rear legs 110(1) and 110(2). The rear end 126b may extend along the longitudinal axis L beyond the second (i.e., rear) cross piece 114(2). The second cross piece 114(2) may be located within the basket 126. The first side 126c, the second side 126d, the front end 126a, and the rear end 126b may extend above the second cross piece 114(2) such that the second cross piece 114(2) is between the front end 126 and the rear end 126b, and between the first side 126c and the second side 126d. In some examples, the second cross piece 124(2) may be positioned closer to the lower end 126f than to the upper end 126e.

[0043] The rear end 126b may have a reinforcing member 128 inside. In one example, the reinforcing member 128 may have a "U" shape with first and second ends 128a and 128b that are attached to the first and second leg assemblies 106(1) and 106(2), respectively. The reinforcing member 128 may be a piece of plastic or other flexible material. In some examples, the reinforcing member 128 may be a bending rod that is received in a tunnel (e.g., a woven tunnel) of the basket 126. The reinforcing member 128 may be positioned along the upper end 126e. The reinforcing member 128 may be configured so that when the child carriage 100 transitions from an extended configuration (Figure 43) to a first folded configuration (Figure 44), the reinforcing member 128 and, consequently, the rear end 126b of the basket 126 retract relative to the first and second rear legs 110(1) and 110(2). For example, the first and second ends 128a and 128b of the reinforcing member 128 can be pivotably attached to the first and second rear legs 110(1) and 110(2), respectively, so that the reinforcing member 128 rotates relative to the first and second rear legs 110(1) and 110(2) around a pivot axis when the child carriage 100 transitions from an extended configuration (Figure 43) to a first folded configuration (Figure 44). The pivot axis can extend along the lateral direction A. The reinforcing member 128 can also bend or move when the child carriage 100 transitions from a first folded configuration (Figure 44) to a second folded configuration (Figure 45). Thus, the child carriage 100 can transition to the first and second folded configurations with the basket 126 still attached. This is made possible, at least in part, by at least one or both of the following: (1) the basket 126 extends beyond the rear legs 110(1), 110(2); and the reinforcing member 128 bends and / or pivots while the child carriage 100 is folded.

[0044] Referring to Figures 46 to 48, a child carriage 100 with a basket 126 according to another example is shown. The basket 126 has a front end 126a, a first side 126c, a second side 126, an upper end 126e, and a lower end 126f, configured in the same way as discussed above in Figures 43 to 45. The basket 126 also has a rear end 126b, configured differently from the rear end 126b discussed above in Figures 43 to 45. In this example, the rear end 126b extends beyond at least a portion of the rear legs 110(1) and 110(2). The rear end 126b includes a planar reinforcing member 128. The reinforcing member 128 may be a piece of plastic or other flexible material. The reinforcing member 128 may extend from the upper end 126e to the lower end 126f. The reinforcing member 128 may extend from the first side 126c to the second side 126d. Each of the first and second sides 126c and 126d may have at least one folding mechanism 130, such as an accordion-type folding mechanism, which allows the rear end 126 to move between an open position (illustrated) and a closed position, and the rear end 126 extends further along the longitudinal direction L from the first and second rear legs 110(1) and 110(2) in the open position than in the closed position. The child carriage 100 may have at least a pair of magnets configured to hold the rear end 126b in the closed position and to move the basket 126 to the open position by separating them. For example, a pair of magnets may comprise at least one first magnet 121 positioned on the frame 102 and at least one second magnet 123 positioned on the basket 126 (e.g., on the rear end 126b or on the fabric between adjacent folds 130) configured to engage with at least one first magnet 121. In some examples, the child carriage 100 may have 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 and second connecting parts 124(1), 124(2), such as one of the rear ends of the first and second connecting parts 124(1), 124(2).

[0045] Infant car seat with push handle Returning to Figures 10 and 11, an example of a child carrier 200 is shown. The child carrier 200 may be installed within an infant car seat (also known as an infant carrier). Typically, the infant car seat 200 comprises an infant car seat body 202. The body 202 may define a seat shell. The infant car seat body 202 has an upper end 202a and a lower end 202b that are opposite to each other along the vertical direction V. The upper end 202a defines a recess 204 that extends inward toward the lower end 202b and terminates with a seat surface 206 configured to support an infant. The seat surface 206 may comprise a seat back 206a and a seat bottom surface 206b. The underside of the seat bottom surface 206b is shown in Figure 11. Although not shown, the infant car seat 200 may include a textile product placed within the recess 204 that is configured to provide cushioning for the infant.

[0046] The lower end 202b has a bottom surface 208 configured to rest on the bottom surface of the vehicle seat when the infant car seat 200 is installed in the vehicle. The infant car seat body 202 has a first or front end 202c and a second or rear end 202d, located opposite 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 back of the vehicle seat in which the infant car seat 200 is installed. Conversely, the rear end 202d is configured to face away from the back of the vehicle seat in which the infant car seat 200 is installed. When a child is seated 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 comprises a first side 202e and a second side 202f, which are opposite to each other along the lateral direction A.

[0047] In some examples, the base surface 208 may be curved as it extends along the longitudinal direction L so that the infant car seat 200 can rock back and forth along the longitudinal direction L when the infant car seat 200 is supported on the floor. For example, the base surface 208 may be curved so that when the infant car seat 200 is placed on a plane, a portion of the base surface 208 between the front end 202c and the rear end 202d contacts the plane, and the base surface 208 is separated from the plane at one or both of the front end 202c and the rear end 202d. However, it is understood that the base surface 208 does not necessarily need to be curved.

[0048] In some examples, the lower end 202b may comprise 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 on the first side 202e, and the second rail 210(2) may be defined on the second side 202f. Each of the first and second rails 210(1) and 210(2) may have an inner and outer surface opposite to each other along the transverse direction A. Each of the first and second rails 210(1) and 210(2) may have a length L along the longitudinal direction L that is greater than the width of rails 210(1) and 210(2) along the transverse direction A. Thus, each rail 210(1) and 210(2) may have an elongated length 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 rail 210(1) may face the inner surface of the second rail 210(2) so as to define a space 212 between them. Each rail 210(1), 210(2) may have a portion of the bottom surface 208. In alternative examples, it is understood that the lower end 208 does not need to have the first and second rails.

[0049] The infant car seat 200 may have at least one coupling configured to connect with the child carriage 100 such that the movement of the infant car seat 200 relative to the child carriage 100 is limited along at least one of the vertical direction V, the longitudinal direction L, and the lateral direction A. Figures 10 and 11 show specific examples of couplings that may be used to connect the infant car seat 200 to the child carriage 100, but it will be understood that the infant car seat 200 may be connected to the child carriage 100 using any other suitable coupling. In some examples, as shown in Figures 10 and 11, the at least one coupling may comprise a first pair of couplings 214(1), 214(2). The first coupling of the first pair, 214(1), may be located on the first side 202e of the infant car seat 200. The second coupling 214(2) of the first pair may be positioned on the second side 202f of the infant car seat 200. Each of the first and second couplings 214(1), 214(2) defines a projection or opening 216 configured to engage with the other of the projection and opening 118 of the child carriage 100. Each side 202e, 202f and each coupling 214(1), 214(2) may engage with different lateral sides of the child carriage 100 to restrict the movement of the child carrier along the lateral direction A. The projection or recess 216 of each coupling 214(1), 214(2) may be configured to engage with the other of the projection and opening 118 of the child carriage 100 along the lateral direction A to restrict the movement of the infant car seat 200 along the vertical direction V (for example, along at least one of the upward and downward directions).

[0050] Figures 10 and 11 show an example in which each coupling portion 214(1), 214(2) is equipped with a movable latch defining a projection 216 extending outward from the side of the infant car seat 200. The first coupling portion 214(1) may be equipped with a projection 216 extending outward from the first side 202e of the infant car seat 200. The projection 216 may be movably mounted relative to the car seat body 202 such that the projection 216 is configured to retract inward into the first side 202e of the car seat body 202 and extend outward from the first side 202e of the car seat body 202. The projection 216 of the first coupling portion 214(1) may be subjected to a spring load so as to be biased toward the extended position. The first coupling portion 214(1) may be configured to connect to the first coupling portion 116(1) of the child carriage 100. For example, the projection 216 of the first coupling portion 214(1) may be configured to be received by the opening 118 of the first portion 116(1) of the child carriage 100.

[0051] The second coupling portion 214(2) of the first pair may be positioned on the second side 202f of the infant car seat 200. The second coupling portion 214(2) may include a projection 216 extending outward from the second side 202f of the infant car seat 200. The projection 216 may be movably mounted relative to the car seat body 202 such that the projection 216 retracts into the second side 202f of the car seat body 202 and extends outward from the second side 202f of the car seat body 202. The projection 216 of the second coupling portion 214(2) may be subjected to a spring load so as to be biased to an extended position. The second coupling portion 214(2) may be configured to connect to the second coupling portion 116(2) of the child carriage 100. For example, the projection 216 of the second coupling portion 214(2) may be configured to be received within the opening 118 of the second coupling portion 116(2) of the child carriage 100.

[0052] At least one coupling may comprise at least one other coupling, such as a second pair of couplings 218(1), 218(2). Each of the at least one other couplings 218(1), 218(2) may comprise a movable latch 220 configured to engage with an engagement surface (e.g., 120(1), 120(2)) of the child carriage 100 to limit the movement of the infant car seat 200 relative to the child carriage 100 along at least one of the vertical direction V and the longitudinal direction L. Each of the at least one other couplings 218(1), 218(2) may be offset from the first pair of couplings 214(1), 214(2) along the longitudinal direction L. For example, each of the at least one other couplings 218(1), 218(2) may be positioned closer to the front end 202c than the first pair of couplings 214(1), 214(2). Each of at least one other coupling portion 218(1), 218(2) may be positioned forward of the handle hubs 228(1), 228(2) (as discussed below). Each of at least one other coupling portion 218(1), 218(2) may be positioned at the lower end 202b of the infant car seat 200, such as on the underside of the infant car seat 200.

[0053] Figures 10 and 11 show one specific example defining a movable hook in which each movable latch 220 engages with one of the corresponding couplings 120(1), 120(2) of the child carriage 100. Each movable latch 220 may be located in a recess of the infant car seat 200, such as within the bottom surface 208, extending toward the lower end 202b. In alternative examples, it is understood that each movable latch 220 may be defined in a shape other than a hook and may be oriented in a different manner. For example, each movable latch 220 may be a movable bar, and each coupling 120(1), 120(2) of the child carriage 100 may define a hook that receives the movable bar. The couplings 218(1) and 218(2) may be the same couplings used to attach the infant car seat 200 to the car seat base (500 in Figures 13A and 13B) for mounting the infant car seat 200 onto the vehicle seat. In other words, each coupling 218(1) and 218(2) may be configured to removably couple to the coupling (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) along the upward direction. Each of at least one other coupling 218(1) and 218(2) may be configured to engage with the coupling (508 in Figures 13A and 13B) along the downward direction.

[0054] Referring briefly to Figures 13A and 13B, the car seat base 500 includes a lower end 502 configured to sit on the vehicle seat when the car seat base 500 is mounted in the vehicle. The car seat base 500 includes an upper end 504 configured to support the infant car seat 200. In some examples, the car seat base 500 may define at least one recess 506 extending into the upper end 504 toward the lower end 502. The recess 506 may be configured to receive the lower portion of the infant car seat 200 internally. The car seat base 500 may include at least one coupling portion 508, such as a pair of coupling portions 508 offset from each other along the lateral direction A. Each coupling portion 508 may be located within at least one recess 506 of the car seat base 500. Each coupling 508 may be configured to connect to one of the couplings 218(1) or 218(2) of the infant car seat 200 so as to prevent the infant car seat 200 from being removed along the vertical direction V. The couplings 508 may be configured in any preferred manner. In some examples, each coupling 508 may include a rod configured to engage with a hook defined by each of the couplings 218(1) or 218(2) of the infant car seat 200.

[0055] Referring back to Figures 10 and 11, the infant car seat 200 may include at least one actuator 224 configured to be operated by a caregiver to transition the couplings 214(1), 214(2) and / or the couplings 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 operated by a caregiver to release (1) the couplings 214(1), 214(2) of the infant car seat 200 from the couplings 116(1), 116(2) of the child carriage 100, and / or (2) the couplings 218(1), 218(2) of the infant car seat 200 from the couplings 120(1), 120(2) of the child carriage 100. Furthermore, at least one actuator 224 may be configured to be operated by a caregiver to release the couplings 218(1), 218(2) of the infant car seat 200 from the coupling 508 of the base 500. For example, when operated by a caregiver, the actuator 224 may be configured to retract the couplings 214(1) and 214(2) of the infant car seat 200 toward the seat body 202. When operated by a caregiver, the actuator 224 may be configured to move the movable latches 220 of the couplings 218(1), 218(2) to disengage them from the couplings 120(1), 120(2) of the child carriage 100. In some examples, the actuator 224 may include a handle that is engaged by a caregiver to operate the actuator 224. In some examples, the actuator 224 may be located on the underside of the seat body 202 near the rear end 202d of the seat body 202. However, it is understood that the actuator 224 may be located elsewhere.

[0056] Referring to Figures 10 to 12B, the infant car seat 200 may be equipped with a handle 226. The infant car seat handle 226 may be configured to move between a retracted position (Figure 12A) in which the handle 226 can be grasped by a caregiver for transporting the infant car seat 200, and an extended position (Figure 12B) in which the handle 226 can be used to push the child carriage 100 when the car seat 200 is coupled as shown in Figure 1. Thus, the infant car seat handle 226 may be referred to as a pushing and carrying handle. The handle 226 may have first side bars 227a and second side bars 227b spaced apart from each other along the lateral direction A. The handle 226 may define a space between the first side bars 227a and the second side bars 227b. The space may have a width greater than the width of the car seat body 202. The handle 226 may have a grip bar 227c that defines a surface to be gripped by a caregiver for transporting and / or pressing the infant car seat 200. The grip bar 227c may extend from a first handle side bar 227a to a second handle side bar 227b.

[0057] 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 connect the first handle side bar 227a of the infant car seat bundle 226 to the first side 202e of the car seat body 202, such that the handle 226 is selectively rotatable relative to the car seat body 202. Similarly, the second handle hub 228(2) may be configured to connect the second handle side bar 227b of the infant car seat handle 226 to the second side 202f of the car seat body 100, such that the handle 226 is selectively rotatable 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 226c being attached to the first and second handle portions 226a and 226b such that the third handle portion 226c is nested within the first and second handle portions 226a and 226b, respectively. The first handle portion 226a extends from the first hub 228(1) and defines a portion of the first handle side bar 227a. The second handle portion 226b extends from the second hub 228(2) and defines a portion of the second handle side bar 227b. Each handle portion 226a and 226b may have a tubular shape. The third handle portion 226c is tubular and may have a "U" shape, with the "U" shaped end attached to the first and second handle portions 226a and 226b. For example, the "U" shaped end may be received within the first and second handle portions 226a and 226b in order to translate within them. The bottom of the "U" shape may define a grip bar 227c. In some examples, the infant seat handle 226 may have a grip 226d positioned on the third handle portion 226c for gripping by a caregiver. The grip 226d may be a flexible surface such as rubber.

[0058] Referring to Figure 14, the infant car seat handle 226 may be configured to rotate selectively between several different positions. For example, the handle 226 may be configured to rotate to a first rotational position (position A) at an angle upward away from the seat body 202, with the handle 226 extending toward the front end 202c of the seat body 202. The first rotational position may be oriented to allow a caregiver to use the handle 226 to push the child carriage 100 when the car seat 200 is connected. The first position may also be referred to as the “angled position” or “pressing position”. The handle 226 may be configured to rotate to a second rotational position (position B) with the handle 226 extending upward along the vertical direction V. The second rotational position may be oriented to allow a caregiver to use the handle 226 to carry the infant car seat 200. The second rotational position may also be referred to as the “upright position” or “carrying position”. The handle 226 may be configured to rotate to a third rotational position (position C) at an angle upward, away from the seat body 202, as the handle 226 extends toward the rear end 202d of the seat body 202. The handle 226 may be configured to rotate to a fourth rotational position (position D) at an angle toward the rear end 202d of the car seat 200 along the longitudinal direction L. The handle 226 may be configured to rotate to a fifth rotational position (position E) at an angle downward, away from the car seat body 202, as the handle 226 extends toward the rear end 202d of the car seat 200. In alternative examples, it is understood that one or more of the third, fourth, and fifth rotational positions may be omitted.

[0059] The operation of the handle 226 will now be described. Generally, the infant car seat 200 may be configured such that when the handle 226 is in a first position (also referred to as the pressed position or position A), the handle 226 can move from the retracted position to the extended position, but cannot move when the handle 226 is in one or more other positions. In some examples, the infant car seat 200 may be configured such that when the handle 226 is in the first rotation position (position A), the handle 226 can move only from the retracted position to the extended position. The infant car seat 200 may include at least one handle extension stop (e.g., 244 in Figures 20-22, which will be discussed further below) configured to prevent the handle 226 from moving from the retracted position to the extended position when the handle 226 is not in the pressed position. Therefore, the infant car seat 200 may be configured such that the handle 226 does not move to the extended position when the handle 226 is in the second, third, fourth, and fifth rotation positions, as shown in Figure 14. The infant car seat 200 may include at least one handle extension lock (e.g., 246 in Figures 23-25, which will be discussed further below) configured to selectively lock the handle 226 in the extended and retracted positions while the handle 226 is in the pressed position. The handle extension lock may be activated by a caregiver while the handle 226 is in the pressed position to move the handle extension lock between a locked position where the handle 226 is not extended or retracted and an unlocked position where the handle 226 is allowed to extend or retract. If a caregiver attempts to activate the handle extension lock while the handle 226 is not in the pressed position, a handle extension stop (e.g., 244 in Figures 20-22) can prevent the handle 226 from extending.

[0060] The infant car seat 200 may be configured to prevent the handle 226 from rotating while the handle 226 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, which will be discussed further below) configured to prevent the handle 226 from rotating while the handle 226 is in the extended position. Thus, the handle 226 may be prevented from rotating to the second, third, fourth, and fifth rotation positions when the handle 226 is in the extended position, as shown in Figure 14. The infant car seat 200 may include at least one handle rotation lock (e.g., 230 in Figure 15, which will be discussed further below) configured to be operated by a caregiver to selectively lock the handle 226 to different rotation positions while the handle 226 is in the retracted position. The handle rotation lock can be moved between a locked position, which prevents the handle 226 from rotating from a selected rotation position, and an unlocked position, which allows the handle 226 to rotate to one of the other rotation positions. If a caregiver attempts to activate 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) can prevent the handle 226 from rotating.

[0061] Referring more specifically to Figures 15 to 17, an example of a rotation lock 230 implemented inside one of the handle hubs 228(2) is shown. It is understood that other rotation locks 230 may also be implemented inside the other of the handle hubs 228(1). Furthermore, it is understood that the rotation lock 230 may be implemented in another preferred manner. The rotation lock 230 comprises a lock plate 234 that defines multiple rotational positions of the handle 226. For example, the lock plate 234 may have a surface that defines a slot 236 inside. The slot 236 may have a circular or partially circular portion 236a and a plurality of grooves 236b that open into the circular or partially circular portion 236a and are spaced circumferentially apart 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 rotation lock 230 may include a rotation latch 238 having a projection 238a, such as a pin, that extends from there into the slot 236. The projection 238a may be configured to selectively receive into a groove 236b in order to lock the handle 226 in different rotational positions.

[0062] 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 projections spaced circumferentially apart from one another. At least one recess of the rotary latch 238 may be configured to selectively receive the projections so as 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 projections, and the rotary latch may define at least one projection or groove configured to selectively engage with the grooves or projections so as to selectively lock the handle in different rotational positions.

[0063] The rotary latch 238 is configured to translate between a locked position (Figure 16) in which the rotary latch 238 engages with the locking plate 234 (for example, the projection 238a is received in one of the grooves 236b corresponding to one of the rotational positions) and an unlocked position (Figure 17) in which the rotary latch 238 disengages from the locking plate 234 (for example, the projection 238a is moved out of one of the grooves 236b and into the circular or partially circular portion 236a of the slot 236). The rotary latch 238 can be configured to rotate the handle 226 by translating along the respective axes of the first and second handle portions 226a, 226b, thereby disengaging the rotary latch 238 from the locking plate 234 (for example, the projection 236a can be removed from one of the grooves 236). The handle 226 can then be rotated to other rotational positions. The rotary latch 238 (and projection 238a) is rotatably fixed to the handle 226, and the rotation of the handle 226 causes the rotary latch 238 (and projection 238a) to rotate correspondingly relative to the lock plate 234. Both the handle 226 and the rotary latch 238 may be configured to rotate around a pivot 240. The pivot 240 can define a pivot axis that extends along the lateral direction A. The rotary latch 238 may define a slot 238b that, by receiving the pivot 240, causes the rotary latch 238 to translate within the slot 238b as it translates between the locked and unlocked positions. When the handle 226 is rotated to another rotation position, the rotary latch 238 (and groove 238a) may be moved to a locked position in which the rotary latch 238 engages with the lock plate 234 (for example, the projection 238a is received in a groove 236b corresponding to the other rotation position). The rotary latch 238 can be spring-biased so that it engages with the lock plate 234 when the rotary actuator 232 is released (for example, so that the projection 238a of the rotary latch 238 moves toward one of the grooves 236b).

[0064] The infant car seat 200 may include a rotary actuator 232 configured to be operated by a caregiver to move at least one rotary lock 230 from a locked position (Figure 16) that prevents the handle 226 from rotating to an unlocked position (Figure 17) that allows the handle 226 to rotate. The rotary actuator 232 includes a movable body 235 that defines an engagement surface 235a (shown in Figure 15) configured to be engaged by a caregiver in order to operate the rotary actuator 232. In one example, the movable body 234 may have the shape of a handle, positioned around one of the first and second handle portions 226a, 226b and configured to translate along the lower handle portion 226a. The movable body 235 may have a tubular shape or other preferred shape such as a collar, 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 a rotary latch 238. The movement of the movable body 235 away from the hub 228(2) along the selection direction DS results in a corresponding movement of the wire or cable 236 along the selection direction DS, and the corresponding movement of the rotary latch 238 along the selection direction DS disengages the rotary latch 238 from the lock plate 234 (for example, moving the projection 238a out of one side of the groove 236b of the lock plate 234). In alternative examples, it is understood that the rotary actuator 232 may be configured in another preferred manner. For example, the movable body 235 may be implemented as a push button instead of a handle. In other examples, the movable body 235 may be located in other positions, such as the "U" shaped bottom of the third handle portion 226c (i.e., the gripping bar 227c) or one of the handle hubs 228(1), 228(2).

[0065] Referring to Figures 18 and 19, the rotation stop 242 is configured to prevent the handle 226 from rotating when the handle 226 is in the extended position. Note that the rotation stop 242 is hidden in Figures 15 to 17 in order to better see the rotation latch 238. The rotation stop 242 may be configured to move between (i) a blocked position (Figure 19) in which the stop 242 interferes with the rotation latch 238, preventing the rotation latch 238 from moving to the unlocked position (thus preventing the handle 226 from rotating), and (ii) a released position (Figure 18) in which the interference between the stop 242 and the rotation latch 238 is eliminated, allowing the rotation latch 238 to move to the unlocked position (thus allowing the handle 226 to rotate). Figures 18 and 19 show an example of the rotation stop 242, but it is understood that the rotation stop 242 may be implemented in any other preferred manner.

[0066] The rotary stop 242 may have a first engagement surface 242a configured to engage with the rotary latch 238 when in a blocked position that interferes with the rotary latch 238. The rotary stop 242 may have a second engagement surface 242b configured to engage with a third handle portion 226c so that the rotary stop 242 moves to the release position. In particular, the third handle portion 226c may be nested with respect to the first and second handle portions 226a and 226b between the extended and retracted positions, as discussed above. As shown in Figure 18, when the third handle portion 226c is in the retracted position, the third handle portion 226c can move the rotary stop 242 to the release position by engaging with the second engagement surface 242b. Furthermore, as shown in Figure 19, when the third handle portion 226c is in the extraction position, the third handle portion 226c can be moved away from the second engagement surface 242b, thereby moving the rotation stop 242 to the block position. The rotation stop 242 may be spring-biased toward the block position. The rotation stop 242 may be configured to rotate around the pivot 240.

[0067] Returning to Figures 20 and 22, the handle extension stop 244 is configured to prevent the handle 226 from extending when the handle 226 is not in the pressed position (i.e., not in position A in Figure 14). The handle extension stop 244 may be configured to move between the released position (Figures 20 and 21) and the blocked position (Figure 22). For example, the handle extension stop 244 may be configured to rotate around a pivot axis between the released position and the blocked position. The handle extension stop 244 and the pivot axis may be located inside the respective handle hubs 228(1) and 228(2). In the blocked position, the handle 226 is in a position other than the pressed position, and the handle extension stop 244 prevents the handle 226 from moving to the extended position. For example, the handle extension stop 244 may include a projection 244a that extends into the third handle position 226c through an opening in one of the first and second handle portions 226a, 226b while the handle extension stop 244 is in the blocked position (Figure 22). The projection 244a blocks the extension of the third handle portion 226c. The projection 244a may be located inside the first and second handle hubs 228(1), 228(2), respectively. The handle extension stop 244 is moved toward the release position (Figures 20 and 21) by rotating the handle 226 to the pressed position. In the release position, the projection 244a is removed from the third handle portion 226c so that the handle 226 can be extended. The handle extension stop 244 may be spring-biased toward the unlocked position. While the handle extension stop 244 is in the released position, and the handle extension lock 246 (discussed below) is in the unlocked position, the handle 226 is allowed to move from the retracted position to the extended position. The handle extension stop 244 may be configured to prevent the handle 226 from extending while the handle 226 is in the transport position (position B), regardless of whether the handle extension lock 246 is in the locked or unlocked position.

[0068] The handle extension stop 244 may have a first side defining a projection 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 rides up along one of the corresponding inner surfaces of the handle hubs 228(1), 228(2). The inner surface prevents the handle extension stop 244 from rotating outward, thereby keeping the handle extension stop 244 in a blocked position. When the handle 226 is rotated to a selected position (e.g., the pressed position shown in Figures 20 and 21), the second side 244b of the second handle extension stop 244 aligns with an opening 245 on the inner surface, thereby rotating the handle extension stop 244 outward, at least partially through the opening, to a released position. The handle extension stop 244 can be entirely housed within one of the corresponding housings of the handle hubs 228(1) and 228(2), and the outer portion of the housing is hidden in Figure 20 so that the handle hub is not visible from the inside.

[0069] Returning to Figures 23-25, the handle extension lock 246 is configured to selectively lock the handle 226 in the retracted and extended positions. The handle extension lock 246 may be implemented in one of the first and second handle sections 226a, 226b. It is understood that other handle extension locks 246 may also be implemented inside the other of the first and second handle sections 226a, 226b. Furthermore, although Figures 23-25 ​​show an example of a handle extension lock 246, it is understood that the handle extension lock 246 may be implemented in other preferred forms.

[0070] The handle extension lock 246 may include a handle extension latch 248 configured to move between a locked position (Figure 25) and an unlocked position. In the locked position, the latch 248 prevents the handle 226 from moving between the extended and retracted positions. 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 permitted to move between the extended and retracted positions. When the handle extension stop 244 is in the blocked position, the handle 226 cannot be extended, regardless of whether the handle extension lock 246 is in the locked or unlocked position.

[0071] The handle extension latch 248 may include a projection 248a configured to move between a locked position and an unlocked position. The projection 248a can move along a direction angularly offset from the axis AH of the handle 226, for example, in a direction perpendicular thereto. In the locked position, the projection 248a extends into an opening in one of the first and second handle portions 226a, 226b and into an opening in the third handle portion 226c, so as to block the extension of the third handle portion 226c. In some examples, the handle portions 226a, 226b may have multiple openings offset from each other along their axes, each opening may correspond to a different extension position. In the unlocked position, the projection 248a is removed from the opening in the third handle portion 226c, thereby allowing the third handle portion 226c to extend or retract.

[0072] The handle extension lock 246 may include a latch guide 250 configured to guide the 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 each of the hubs 228(1) and 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 the corresponding surface of the latch 248. For example, the latch guide 250 may include a slot 250a that is angularly offset from the selection direction DS, and the latch 248 may have a pin 248b that is received in the slot 250a. When the latch guide 250 is moved away from each of the hubs 228(1) and 228(2) along the selection direction, the pin 248b translates along the slot 250a, causing the projection 248a to move out of the opening in one of the first and second handle portions 226a and 226b and out of the third handle portion 226c (i.e., moving the latch 248 to the unlocked position). When the latch guide 250 is moved toward each of the hubs 228(1) and 228(2) along the selection direction, the pin 248b translates along the slot 250a, causing the projection 248a to move toward the opening in one of the first and second handle portions 226a and 226b and toward the third handle portion 226c (i.e., moving the latch 248 to the locked position).

[0073] The infant car seat 200 may include a handle extension actuator 252 (labeled in Figure 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 push button that defines the engagement surface 254a. The push button can be actuated by pressing the push button into the handle 226 along the actuator direction DA, such as within a third handle portion 226c or another handle portion.

[0074] The handle extension actuator 252 may include a link 258, such as a wire or cable, that extends from the movable body 254 to the handle extension lock 246. The handle extension actuator 252 may be configured to move the link 258 in response to the movement of the movable body 254 by the caregiver, thereby moving the handle actuation lock 246 between a locked position and an unlocked position. The handle extension actuator 252 may be configured to convert the translational movement of the movable body 254 into the handle 226 along the action direction DA into the link 258 along the handle 226. For example, the inside of the movable body 254 may define at least one inclined surface 254b, and the handle extension actuator 252 may include at least one wedge 256 having at least one inclined surface 256a that engages with at least one inclined surface 254b of the movable body 254. The handle extension actuator 252 may be configured to move at least one wedge 256 in a direction perpendicular to the action direction DA, such that when the movable body 254 is pushed by the caregiver, at least one inclined surface 254b of the movable body 254 translates along at least one inclined surface of at least one wedge 256. This, in turn, moves the link 258 along the handle 226 and moves the handle actuation lock 246. In other examples, it is understood that the handle extension actuator 252 may be implemented in a different preferred manner. For example, the handle extension actuator 252 may be implemented as a handle instead of a button, and / or in other positions, such as along one of the first and second handle portions 226a, 226b.

[0075] Bassinet or carrycot with push handle Although not illustrated, in some examples the child carrier may be a bassinet or a carrycot. The bassinet or carrycot may have a body and / or frame, as is conventionally known. The bassinet or carrycot may have a handle configured as discussed above in relation to the infant car seat 200, and the handle may be configured to operate in relation to the handle 226 of the infant car seat 200 in the manner described above. Furthermore, the bassinet or carrycot may have couplings similar to couplings 214(1) and 214(2), and optionally couplings similar to couplings 218(1) and 218(2). It is understood that the above descriptions of couplings 214(1), 214(2), 218(1), and 218(2) are equally applicable to the bassinet or carrycot.

[0076] Mobile Organizer Returning to Figures 29-33, the mobile system 10 may optionally include a mobile organizer 300 that can be configured to hold at least one item, such as a caregiver's beverage container, a portable device, or other item. The organizer 300 may be configured to be detachably coupled to the handle 226 of a child carrier (e.g., 200, 400). For example, the organizer 300 may be configured to be coupled to the handle 226 in space between the first handle side bar 227a and the second handle side bar 227b, and between the grip bar 227c and the seat of the child carrier. The organizer 300 may be configured to be coupled to any suitable handle of any suitable child carrier (e.g., any infant car seat, toddler seat, bassinet, or carrycot).

[0077] The organizer 300 may have a first organizer side 300a and a second organizer side 300b that are offset from each other along the lateral direction A. In some examples, 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.

[0078] The organizer 300 may include a tray 302 and a storage container 304 coupled to the tray 302 and positioned below the tray 302. The tray 302 may be formed from a preferably rigid material, such as a polymer or other suitable material. The tray 302 may have an upper tray end 302a defining the top surface and a lower tray end 302b spaced apart from the upper tray end 302a along the vertical direction V. The tray 302 may define at least one tray opening, such as a plurality of tray openings, extending into the upper tray end 302a toward the lower tray end 302b. For example, the tray 302 may define a circular tray opening 302c extending into the upper tray end 302a. The circular tray opening 302c may have a size and shape that allows it to receive a beverage container inside, such as a can, bottle, or cup. As another example, tray 302 may, as an addition or alternative, define a tray opening 302d that defines a recess extending into the upper end 302a of the tray and being closed at the bottom of the tray opening 302d. As yet another example, tray 302 may, as an addition or alternative, define a tray opening 302e that defines a through-hole extending through tray 302 (i.e., through the upper end 302a and the lower end 302b of the tray) so that the tray opening 302e opens to the storage container 304 below tray 302. In some examples, tray 302 may be provided with a lid 306 that closes to cover at least one of the tray openings and opens to give the caregiver access to the contents of at least one of the tray openings.

[0079] The storage container 304 may have an upper container end 304a and a lower container end 304b spaced apart from the upper container end 304a along the vertical direction V. The upper container end 304a may define at least one container opening 304c that extends internally and ends in front of the lower container end 304b, thereby closing at least one container opening 304c. The at least one container opening 304c may be aligned along the vertical direction with at least one of the openings of the tray 302. For example, at least one container opening 304c may be aligned with a tray opening 302e so that articles can be placed into the at least one container opening 304c through the tray opening 302e. In some examples, at least one tray opening 302e may be aligned along the vertical direction with the entire tray opening.

[0080] In some examples, the tray 302 and the storage container 304 may each have cross-sectional shapes perpendicular to each other in the vertical direction, and the cross-sectional shapes of the tray 302 and the storage container 304 may coincide with and / or coincide with each other. In an alternative example, the tray 302 may have a larger cross-sectional shape than when the storage container 304 is positioned below only a portion of the tray 302. When the tray 302 is coupled to the storage container 304, the tray 302 may act as the top of the storage container 304.

[0081] Returning briefly to Figures 34 and 35, in some examples, the organizer 300 may be configured to transition between a compact configuration (Figure 34) and an expanded configuration (Figure 35). In particular, the tray 302 may be movably coupled to the storage container 304 so that the vertical distance between the tray 302 and the storage container 304 can be selectively increased or decreased. In other words, the organizer 300 can transition from a compact configuration to an expanded configuration by increasing the distance between the tray 302 and the storage container 304, and from an expanded configuration to a compact configuration by decreasing the distance between the tray 302 and the storage container 304. When the organizer 300 is in a compact configuration, the tray 302 and the storage container 304 may be in contact with each other. The organizer 300 has a larger internal storage capacity when it is in an expanded configuration than when it is in a compact configuration.

[0082] The organizer 300 may include a flexible material 308 coupled to a tray 302 and a storage container 304. The flexible material 308 can be a woven fabric such as a mesh fabric or any other suitable material. In one example, the storage container 304 may be made of a semi-rigid material such as ethylene vinyl acetate (EVA), which is less rigid than the tray 302 but more rigid than the flexible material 308, and the flexible material 308 may be a woven fabric that is thermoformed onto the storage container 304. The flexible material 308 may have a tubular shape defining an upper end 308a and a lower end 308b that are offset from each other along the vertical direction V. The flexible material 308 may define a receiving space extending from the upper end 308a to the lower end 308b. The upper end 308a may be coupled to the tray 302, such as the lower end 302b of the tray 302. The lower end 308b can be connected to the upper end 304a of the storage container 304, or the storage container 304. Alternatively, the lower end 308b can surround the lower end 304b of the storage container 304.

[0083] When the organizer 300 is in an expanded configuration, the flexible material 308 can define the side of the organizer 300 relative to the container articles in the receiving space. When the organizer 300 is in a compact configuration, the flexible material 308 can be folded inward within the organizer 300. Although not shown, in some examples, the flexible material 308 may define an access opening on its side between the open upper ends 308a and 308b to provide the caregiver with access to the receiving space within the flexible material 308. Additionally or alternatively, the caregiver may access the receiving space through an opening 203e defining a through-hole extending through the tray 302.

[0084] The organizer 300 may include fasteners 310 configured to selectively secure the organizer 300 in a compact configuration. For example, the fasteners 310 may include a zipper having a first tape portion 310a having a first plurality of teeth and a second tape portion 310b having a second plurality of teeth configured to engage with the first plurality of teeth. The tray 302 may include a first tape portion 310a that can be attached to the body of the tray 302, such as the lower end 302b of the tray 302. The storage container 304 may include a second tape portion 310b that can be attached to the body of the storage container 304, such as the upper end 304a of the storage container 304. In an alternative example, the organizer 300 may be implemented with fasteners 310 other than a zipper, such as snaps, buttons, toggle latches, or any other suitable fasteners that can secure the organizer 300 in a compact configuration.

[0085] Referring back to Figures 31 and 32, as discussed above, the organizer 300 may be configured to be detachably attached to the handle 226 of the infant car seat 200. The organizer 300 may define a first coupling portion 312(1) at the first organizer side 300a, which is configured to engage with the first coupling portion 229 (see Figure 26) of the first handle side bar 227a of the handle 226 in order to connect the first organizer side 300a to the first handle side bar 227a. The first coupling portion 312(1) of the organizer 300 may define at least one of a projection and an opening, and the first coupling portion of the handle 226 may define the other of a projection and an opening configured to fit into the first coupling portion 312(1). Similarly, the organizer 300 may define a second coupling portion 312(2) on the second organizer side 300b, which is configured to engage with the second coupling portion 229 of the second handle side bar 227b of the handle 226 in order to connect the second organizer side 300b to the second handle side bar 227b. The first coupling portion 312(2) of the organizer 300 may define at least one of a projection and a locking mechanism, and the second coupling portion of the handle 226 may define the other of a projection and an opening configured to fit into the second coupling portion 312(2).

[0086] Figures 31 and 32 show a specific example in which the first and second couplings 312(1) of the organizer 300 each define a projection, and the coupling 229 of the car seat handle 226 defines an opening for receiving the projection. The first and second couplings 312(1) and 312(2) are attached to the tray 302, but in an alternative example, the couplings may be attached to other parts of the organizer 300. One of the projections of the couplings, such as the projection of the first coupling 312(1), may be positioned and fixed so as not to retract into the organizer 300. As an addition or alternative, another projection of the couplings, such as the projection of the second coupling 312(2), may be configured to selectively extend from the organizer 300 (Figure 32) and retract into the organizer 300 (Figure 33). In such an example, the projection of the second coupling portion 312(2) may be spring-biased to protrude from the organizer 300. The organizer 300 may optionally include an actuator 314 configured to be engaged by a caregiver to move the projection of the first coupling portion 312(1) between an extended position (Figure 32) and a retracted position (Figure 33).

[0087] Now, returning to Figures 24 and 26-28, in some examples, the infant car seat 200 may be configured such that the organizer 300 can only be mounted when the handle 226 is in the extended position. Additionally or 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 attached. For example, the handle 226 of the infant car seat 200 may include at least one organizer latch 260 configured to move between a blocking position (Figure 26) that prevents the organizer 300 from being attached to the coupling 229 of the car seat handle 226, and an unblocking position (e.g., Figure 27) that allows the organizer 300 to be attached to the coupling 229 of the car seat handle 226.

[0088] Each organizer latch 260 may be implemented on one of the handle side bars 227a, 227b. In some examples, each handle side bar 227a, 227b may be provided with an organizer latch 260. Figures 26 and 27 show a specific example of an organizer latch 260, but it is understood that the organizer latch 260 may be implemented in any other preferred manner. The organizer latch 260 may define an opening 260a internally. The organizer latch 260 may be configured such that when the organizer latch 260 is in a non-blocking position (Figure 27), the opening 260a of the organizer latch 260 is substantially aligned with the opening defined by the handle coupling 229. Therefore, one of the couplings 312(1) and 312(2) of the organizer 300 can be inserted through the opening 229 of the handle 226 and into the opening 260a of the organizer latch 260. This is shown in Figure 28. In some examples, the organizer latch 260 may be coupled to a link 258 of the handle extension actuator 252 so that when the caregiver operates the handle extension actuator 252, the organizer latch 260 moves from an unlocked position (Figure 27) to a blocked position (Figure 26). Referring to Figure 28, when the organizer 300 is attached to the car seat handle 226, each of the couplings 312(1) and 312(2) interferes with the movement of the organizer latch 260, preventing the caregiver from operating the handle extension actuator 252. Thus, the handle 226 is prevented from moving from the extended position to the retracted position while the organizer 300 is coupled to the handle 226. Conversely, while the handle extension actuator 252 is operated by the caregiver, the organizer latch 260 is in the blocked position, preventing the organizer 300 from being installed.

[0089] The infant car seat handle 226 may be configured such that when the infant car seat handle 226 is in the retracted position, each organizer coupling portion 229 of the handle 226 is covered by one of the first and second handle portions 226a, 226b. In other words, in the retracted position, each organizer coupling portion 229 can be retracted inward toward one of the first and second handle portions 226a, 226b so that the organizer 300 cannot be coupled to the organizer coupling portion 229.

[0090] Figures 24 and 26-28 illustrate an example in which each organizer coupling 229 of the infant car seat handle 226 is configured to receive projections of couplings 312(1), 312(2) of the organizer 300, but the examples of the present disclosure are not limited thereto. In alternative examples, each organizer coupling 229 of the infant car seat handle 226 may have projections (not shown) extending inward from the handle 226, and each coupling 312(1), 312(2) of the organizer 300 may have an opening configured to receive one of the corresponding projections. In some such examples, the projections of each organizer coupling 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 being attached to the coupling 229. Furthermore, when the organizer 300 is attached to each organizer coupling 229 of the handle 226, each coupling 229 interferes with each of the couplings 312(1) and 312(2) of the organizer 300, thereby preventing each of the couplings 312(1) and 312(2) from retracting into the handle 226. The handle 226 considered above may, as an alternative, be mounted on a child carrier other than an infant car seat, such as on an infant seat 400, or on a bassinet or carrycot. Therefore, the above description can be equally applied to the infant seat 400, or a bassinet or carrycot.

[0091] Infant seat with push handle Returning to Figures 36A to 37B, the mobility system 10 is shown comprising the child carriage 100 of Figures 3 and 4 and a removable child carrier 400, which is an infant seat. The infant seat 400 comprises 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 from one or more tubes. The seat frame 402 comprises first side rails 406 and second side rails 408 spaced apart from each other along the lateral direction A, so as to define an opening or space 410 between which a child is positioned when seated in the infant seat. The infant seat 400 may comprise a seating surface 416a and a textile product 416 disposed within the space 410, configured to provide cushioning to the infant. The textile product 416 may define a seat bottom surface 416b and a seat back surface 416c. The textile product 416 may define a pair of spaced-apart side walls 416d. The seat base 416b and seat back 416c may extend between the side walls 416d. In an alternative example (not shown), the infant seat 400 may comprise a plastic body defining a seating surface 416a, including the seat base 416b and seat surface 416c.

[0092] 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 may have an elongated length 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 406 may have an elongated length along the first direction D1. The seat frame 402 may include a foot rail 412 extending between the first and second side rails 406 and 408. For example, the foot 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 foot rail 412 may extend along a second direction D2 perpendicular to the first direction D1. In some examples, the second direction D2 can be aligned with the lateral direction A. The foot rail 412 may have an elongated section along the second direction D2. Thus, the first side rail 406, the second side rail 408, and the foot rail 412 can together define a "U" shape. The first side rail 406, the second side rail 408, and the foot rail 412 can be separate parts joined to each other, or they can be part of a continuous tube bent to define the shape of the seat frame 402.

[0093] The push handle 404 is configured to be grasped by a caregiver to push the mobility system 10 when the infant seat 400 is attached to the child carriage 100. For example, the push handle 404 may extend above the seat frame 402 so that it is accessible to the caregiver. The infant seat 400 is configured so that the handle 400 can be removed from the child carriage 100 together with the infant seat 400 by removing the infant seat 400 from the child carriage 100.

[0094] The push handle 404 may be configured to move between an extended position and a retracted position. In some examples, the push handle 404 may be configured to move to one or more intermediate positions between the extended position and the retracted position. When the push handle 404 is in the extended position and not in the retracted position, it may extend further above the seat frame 402. In one example, the push handle 404 may be mounted to the seat frame 402 such that the handle 404 is nested with respect to the seat frame 402. For example, the handle 404 may comprise a first handle portion 404a and a second handle portion 404b. The first handle portion 404a may be nested with respect to the first side rail 406, and the second handle portion 404b may be nested with respect to the second side rail 408. The first and second handle projections 404a and 404b may be offset from each other along the lateral direction A. The handle 404 may optionally include a third handle portion 404c extending between the first and second handle portions 404a and 404b. In an alternative example (not shown), the push handle may be rotatably mounted relative to the seat frame at a pivot point such that the handle rotates toward and away from the seat frame along the pivot axis, the pivot axis may extend, for example, along a second direction D2.

[0095] Referring to Figure 38, the infant seat 400 may include at least one handle extension lock 420 configured to selectively lock the handle 404 in the extended and retracted positions. At least one handle extension lock 420 is configured to selectively lock the handle 404 in the retracted and extended positions. Each handle extension lock 420 may be implemented in one of the first and second handle portions 404a and 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 moving between the extended and retracted positions. In the unlocked position, the handle 404 is permitted to move between the extended and retracted positions. For example, the handle extension latch 422 may define a projection 422a configured to move between the locked and unlocked positions. The handle extension latch 422 can be moved angularly offset from the axis AH of the first or second handle portion 404a or 404b, for example, along a direction perpendicular thereto. In the locked position, the projection 422a of the handle extension latch 420a extends into an opening 409 in one of the first and second side rails 406 and 408 such that the projection 422a blocks the extension of the handle 404. One of the first and second side rails 406 and 408 may each have a plurality of openings 409 offset from each other along the axis AH, corresponding to different positions of the handle 404. In the unlocked position, the projection 422a of the handle extension latch 422 is released from the opening 409 in one of the first and second side rails 406 and 408, thereby extending or retracting the handle 404.

[0096] The handle extension lock 420 may include a latch guide 424 configured to guide the movement of the latch 420 between a locked position and an unlocked position. The latch guide 424 may be configured to translate along a selection direction DS along the axis AH of the handle 404. The latch guide 424 may include a guide surface that guides the corresponding surface of the latch 422. For example, the latch guide 424 may include a slot 424a that is angularly offset from the selection direction DS, and the latch 422 may include a pin 422b that is received in the slot 424a. When the latch guide 424 is moved upward along the selection direction DS, the pin 422b translates along the slot 424a, causing the projection 422a to move out of the opening 409 in one of the first and second side rails 406 and 408. As the latch guide 424 is moved downward along the selection direction DS, the pin 422b translates along the slot 424a, causing the projection 422a to move into one of the openings 409 in one of the first and second side rails 406 and 408.

[0097] The infant seat 400 may include a handle extension actuator 426 (labeled in Figure 36A) which is engaged by a caregiver and configured to move a handle extension lock 420 between a locked position and an unlocked position. The handle extension actuator 426 may be implemented in any preferred manner. The handle extension actuator 426 comprises a movable body having an engagement surface which is engaged by a caregiver and configured to actuate the handle extension actuator 426. In one example, the movable body defines a push button which defines the engagement surface. The push button may be actuated by pushing the push button onto the handle 404.

[0098] Continuing to refer to Figure 38, the handle extension actuator 426 may include a link 428, such as a wire, cable, or band, extending from the movable body of the actuator 426 to the handle extension lock 420. The handle extension actuator 426 may be configured to move the link 428 in response to the movement of the movable body by the caregiver, thereby moving the handle actuation lock 420 between a locked position and an unlocked position. The handle extension actuator 426 may be configured to convert the translational movement of the movable body of the actuator 426 into a translational movement along the axis AH of the link 428. In other examples, it is understood that the handle extension actuator 426 may be implemented in other preferred forms. For example, the handle extension actuator 426 may be implemented as a pull handle instead of a button, or as a collar that translates along a portion of the handle 404. The handle extension actuator 426 may also be implemented in locations other than those shown.

[0099] Referring back to Figures 36A to 37B, the infant seat 400 may be configured to transition between an extended configuration (Figure 37A) and a folded configuration (Figure 37B). The frame 402 may have an upper frame end 402a and a lower frame end 402b, so that when a child is seated in the infant 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 legs. The infant seat 400 is configured to transition from an extended configuration to a folded configuration by rotating the upper frame end 402a toward the lower frame end 402b, and to transition from a folded configuration to an extended configuration by rotating the upper frame end 402a toward the lower frame end 402b. 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 pivotably connect the upper end 402a and the lower end 402b of the frame. The first folding hub 418(1) may be attached to the first side rail 406 between the first and second rail ends 406a and 406b of the first side rail 406. Similarly, the second folding hub 418(2) may be attached to the second side rail 408 between the first and second rail ends 408a and 408b of the second side rail 408. The infant seat 400 may be configured to remain fixed to the carriage 100 when the infant seat is in a folded configuration and the carriage 100 is in a first folded configuration, as shown in Figure 37B. As shown in the figure, when both the infant seat 400 and the carriage 100 are folded, the connecting parts 116(1) and 116(2) can be rotated forward so that the upper end 402a of the frame of the infant seat 400, the lower end 402b of the frame of the infant seat 400, and the front legs 108(1) and 108(2) of the carriage 100 can be substantially parallel to each other.

[0100] Returning to Figures 39A to 39C, the infant seat 400 may include at least one folding latch 430 configured to lock the child carriage 100 in a releaseable position when extended. Each folding latch 430 may be located within one of the folding hubs 418(1), 418(2). Each folding latch 430 may be implemented in any preferred manner. Figures 39A to 39C show an example of the first folding hub 418(1). The second folding hub 418(2) may be implemented similarly. However, it is understood that the folding hub 418(1) and the folding latch 430 may be implemented in other preferred manners. The infant seat 400 may include a folding actuator 432 (labeled in Figure 36B) configured to actuate at least one folding latch 430 so as to move the folding latch 430 between an unlocked position that allows the infant seat 400 to be folded and a locked position that prevents the infant seat 400 from being folded. The actuator 432 can be any suitable actuator.

[0101] Generally, each folding hub 418(1), 418(2) has a lower end plate 434 and an upper end plate 436 that are pivotably coupled to each other. The upper end plate 436 is fixed in a positionable manner to the upper end 402a of the seat frame 402 such that the rotation of the upper end 402a of the frame causes a corresponding rotation of the upper end plate 436. The lower end plate 434 is fixed in a positionable manner to the lower end 402b of the seat frame 402 such that the lower end 402b of the frame 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 to one of the upper end plate 436 and the lower end plate 434, and can be configured to releasably engage with the other of the upper end frame 436 and the lower end frame 434 so as to rotatably lock the upper end 402a and the lower end 402b of the frame relative to each other.

[0102] For example, Figures 39A to 39C show one specific example in which a folding latch 430 is rotatably fixed to an upper plate 436 and configured to releasably engage with a lower plate 434. The folding latch 430 is translationally movable relative to the upper plate 436 along the axis of the upper end 402a. The lower plate 434 may define a guide slot 434a and a plurality of recesses 434b, 434c extending from the guide slot 434a. The guide slot 434a may be curved to define an arc or a circle. Each recess 434b, 434c can correspond to a different folding configuration of the infant seat 400. For example, the lower plate 434 may define a first recess 434b corresponding to an extended configuration and a second recess 434c corresponding to a folded configuration. The folding latch 430 includes a projection 430a configured to translate along the guide slot 434a when the infant seat 400 transitions between the folded and extended configurations. The projection 430a may extend through the straight slot 436a of the upper plate 436 toward the guide slot 434a of the lower plate 434 so as to translate along the straight slot 436a. The projection 430a is configured to selectively receive into recesses 434b, 434c so as to rotatably lock the upper frame end 402a and the lower frame end 402b relative to each other in one of the extended and compressed configurations. Figure 39B shows the infant seat 400 in an extended configuration, with the projection 430a of the folding latch 430 received in the first recess 434b, and Figure 39C shows the infant seat 400 in a folded configuration, with the projection 430a of the folding latch 430 received in the second recess 434b.

[0103] The infant seat 400 may optionally include an armbar or child tray 438. The armbar or child tray 438 may be configured to fold together with the seat frame 402. In one example, a folding hub may be configured to guide the armbar or child tray 438 between extended and folded configurations. For example, the armbar or child tray 438 may include a hub 440 having a projection 440a. The lower end plate 434 may have a first groove 434d that receives the projection 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 limits the movement of the projection 440a along the upward direction, and therefore the upward movement of the armbar or tray 438, when the infant seat 400 is in the extended configuration as shown in Figure 39B. The top plate 436 may have a second groove 436b that receives the projection 440a of the hub 440. The second groove 436b has a lower end 436c and a lower end 436d. The lower end 436d restricts the downward movement of the projection 440a when the infant seat 400 is in the extended configuration as shown in Figure 39B, thereby limiting the downward movement of the arm bar or tray 438. When the frame 402 is rotated into the folded configuration, the top plate 436 rotates downward, causing the upper end 436d of the second groove 436b to rotate downward and engage with the projection 440a of the hub 440, thereby driving the projection 440a and, consequently, the arm bar or tray 438 downward as shown in Figure 39C.

[0104] Referring back to Figures 36A to 37B, the infant seat 400 is configured to be detachably coupled to the child carriage 100. The infant seat 400 may have at least one coupling configured to detachably couple the infant seat 400 to the carriage 100. The at least one coupling may comprise a pair of couplings 414(1), 414(2). The first coupling 414(1) of the pair may be configured to be detachably coupled to the first seat coupling 116(1) of the child carriage 100. The first coupling 414(1) may be attached to the first side rail 406 between the first and second rail ends 406a and 406b of the first side rail 406. The second coupling 414(2) of the pair may be configured to be detachably coupled to the second seat coupling 116(2) of the child carriage 100. The second coupling portion 414(2) can be attached to the second side rail 408 between the first and second rail ends 408a and 408b of the second side rail 408.

[0105] Referring to Figures 40A to 42, in some examples, each of the first and second couplings 414(1) and 414(2) of the infant seat 400 may define a receptacle 442 configured to receive one of the corresponding bayonets 117 of the first and second seat couplings 116(1) and 116(2). In alternative examples, the child carriage may be equipped with a receptacle, and the infant seat 400 may be equipped with a bayonet. Each receptacle 442 defines a recess 444 configured to receive one or more of the corresponding bayonet 117, such as the top of the bayonet 117, into its interior. Each of the first and second couplings 414(1) and 414(2) may define a projection or opening 446a configured to engage with the other of the projection and opening 118 of the child carriage 100 (labeled in Figure 5A). Figures 40A to 42 show an example defining projections 446a configured such that each of the first and second couplings 414(1) and 414(2) is received by an opening 118 (labeled in Figure 5A) of the child carriage 100. Each projection 446a extends toward the recess 444 of each coupling 414(1) and 414(2). Each coupling 414(1) and 414(2) can engage different lateral sides of the child carriage 100 to restrict the movement of the infant seat 400 relative to the carriage 100 along the lateral direction A, the vertical direction V, and / or the longitudinal direction L.

[0106] In some examples, each coupling portion 414(1), 414(2) may be equipped with a movable latch 446 having a projection 446a. The movable latch 446 can be movable between a latched position (Figure 41B) and an unlatched position (Figure 41A). In the latched position, the projection 446a may extend into one of the corresponding openings 118 of the seat coupling portions 116(1), 116(2) of the child carriage 100. In the unlatched position, the projection 446a is removed from the opening 118.

[0107] Referring more specifically to Figures 41A to 42, the infant seat 400 may include actuators 450 for each coupling 414(1), 414(2) that are engaged by a caregiver and configured to move the latch 446 between a latched position and an unlatched position. Each actuator 450 can be any suitable actuator. Each actuator 450 may define an operating surface 452, such as a push button, configured to be recessed into one of the corresponding folding hubs 418(1), 418(2). In an alternative example (not shown), each operating surface 452 may define a pull handle. Each actuator 450 may include at least one link 454 that operably connects the engaging surface 452 to the movable latch 446. In one example, at least one link 454 may have at least one inclined surface 454a, such as a pair of inclined surfaces 454a that engage with one corresponding engagement surface 446b of the latch 446, so that at least one engagement surface 454a rides up along at least one inclined surface 454a, thereby causing the latch 446 to pivot between a latched position and an unlatched position.

[0108] Referring back to Figures 40A and 40B, in some examples the infant seat 400 may have at least one additional coupling 456, such as a pair of other couplings 456 positioned in front of or behind a pair of couplings 414(1), 414(2). The pair of other couplings 456 may be offset from each other along the lateral direction A. Each of the at least one additional coupling 456 may be attached to the first and second side rails 406, 408, respectively. Each of the at least one additional coupling 456 may be configured to removably coupling to one of at least one additional coupling 132(1) or 132(2) (labeled in Figure 3) of the child carriage 100. Each of at least one other coupling 456 connects the infant seat 400 to the carriage 100 in such a way that when force is applied to the handle 404 of the infant seat 400 (see Figure 36), the torque applied to the pair of couplings 414(1), 414(2) is limited.

[0109] In some examples, each of at least one other coupling 456 may include a movable latch 458 configured to move between a latched configuration (Figure 40B) and a non-latched configuration (Figure 40A). For example, each movable latch 458 may define a hook configured to pivot between a latched and a non-latched configuration. Each movable latch 458 may be configured to be actuated by an actuator 450. The actuator 450 can be any suitable actuator. In some examples, each movable latch 458 may be actuated by an actuator 450 which also actsuates one of the latches 446. Each actuator 450 may include a link 460 which operably couples one of the latches 446 to a corresponding one of the working surfaces 452. Each link 460 may extend at least partially into one of the first and second side rails 406 and 408. The actuation of the actuator 450 causes the link 406 to translate, thereby allowing the latch 458 to pivot between a latched configuration (Figure 40B) and a non-latched configuration (Figure 40A). The latch 458 can be biased toward a latch configuration.
