[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Application No. 63 / 031,967, entitled "Single to Double Stroller," filed May 29, 2020, U.S. Application No. 63 / 077,938, entitled "Universal Auxiliary Basket for Stroller," filed September 14, 2020, and U.S. Application No. 63 / 126,751, entitled "Single to Double Stroller Improvements," filed December 17, 2020, each of which is incorporated herein by reference in its entirety. [Background technology]

[0002] Child strollers are convenient devices for safely and easily transporting children and have evolved in recent years to become more sophisticated and user-friendly. For example, a single stroller can have user-friendly features for both the parent and the child, such as an adjustable handle height for the parent, a foldable frame, the ability to switch between attaching an infant car seat, bassinet, or child seat to the stroller frame, a large undercarriage basket, and a snack tray for the child. When a child joins the family, it is convenient to have a stroller that can be converted from one that carries one child to one that carries two children. Summary of the Invention [Means for solving the problem]

[0003] The described implementation relates to a child stroller system that can be easily converted from carrying one seated or cradled child (infant, toddler, or small child) to carrying two seated and / or cradled children. A second child-carrying device (infant car seat, bassinet, or car seat) can be added to the stroller without removing the first child-carrying device. The position of both child-carrying devices is adjustable relative to the stroller frame. The stroller system also includes an auxiliary storage basket that can be attached to the seat mount when the seat mount is not in use for the child-carrying device. The auxiliary basket can collapse into a flat configuration when not in use for storage and can stand on its base when removed from the stroller.

[0004] Some implementations relate to a stroller system for transporting one or more children. The stroller system may include a stroller frame including a handle, at least one front leg, and rear legs. The stroller system may further include wheels attached to the at least one front leg and the rear leg for supporting the stroller frame; a first pair of seat adjustment assemblies including a first pair of seat mounts, the first pair of seat adjustment assemblies connected to the stroller frame and arranged to translate the first pair of seat mounts along a first direction; and a second pair of seat adjustment assemblies including a second pair of seat mounts, the second pair of seat adjustment assemblies connected to the stroller frame and arranged to translate the second pair of seat mounts along a second direction different from the first direction. The stroller system may further include a first child carrier mountable to the first pair of seat mounts in a forward-facing orientation and a rearward-facing orientation.

[0005] Some implementations relate to a method of converting a stroller from one that transports one child to one that transports two children. Such a method can include the acts of maintaining a first child carrying device attached to a first pair of translatable seat mounts connected to a frame of the stroller; and mounting a second child carrying device on the second pair of translatable seat mounts. The first child carrying device and the second child carrying device can be mounted on the first pair of translatable seat mounts and the second pair of translatable seat mounts in a forward-facing orientation and a rearward-facing orientation, respectively.

[0006] Some implementations relate to a stroller system for transporting one or more children. The stroller may include a foldable frame including a handle, at least one front leg, and two rear legs; and wheels attached to the at least one front leg and the two rear legs for supporting the foldable frame. The stroller system may further include an adjustment knuckle connecting an adjustable handle portion of the handle to a fixed portion of the handle. The adjustable handle portion may include a grip portion that is grasped by a user to push the stroller. The adjustment knuckle may include a height adjustment actuator for changing the height of the grip portion relative to a surface on which the wheels rest when the foldable frame is unfolded. The adjustment knuckle may also include a fold actuator for actuating folding of the foldable frame and for operating independently of the first actuator.

[0007] Some implementations relate to methods of operating a stroller having a foldable frame supported by wheels. Such methods can include the acts of actuating a height adjustment actuator on an adjustment knuckle located on a handle of the stroller to change the height of a gripping portion relative to a surface on which the wheels rest when the foldable frame is unfolded, the gripping portion being located on an adjustable handle portion of the handle; and actuating a fold actuator on the adjustment knuckle to fold the foldable frame of the stroller, the height adjustment actuator and the fold actuator can be operated independently of each other.

[0008] Some implementations relate to a stroller system for transporting one or more children. The stroller system may include a stroller frame including a handle, at least one front leg, and two rear legs; and wheels attached to the at least one front leg and the two rear legs for supporting the stroller frame. The stroller system may further include a child car seat including a seat frame; and a seat hub connected to the seat frame. The seat hub may include a first plate, a pin carrier, and a second plate, where the first plate has a fixed orientation relative to the seat frame and includes one or more slots; the pin carrier is adjacent to the first plate, is arranged to translate relative to the first plate, and carries at least one pin protruding through the one or more slots; and the second plate has a fixed orientation relative to the stroller frame and includes multiple recline detents for receiving the one or more pins and for providing adjustment and locking of the child car seat to two or more reclined positions.

[0009] Some implementations relate to a stroller for transporting one or more children. The stroller may include a stroller frame including a handle, at least one front leg, and a rear leg, the at least one front leg extending forward of the rear leg. The stroller may further include wheels attached to the at least one front leg and the rear leg for supporting the stroller frame; and a first pair of seat adjustment assemblies including a first pair of seat mounts. The first pair of seat adjustment assemblies may be connected to the stroller frame and may be positioned to translate the first pair of seat mounts along a first direction when a child carrying device is attached to the first pair of seat mounts. The stroller may further include a second pair of seat adjustment assemblies including a second pair of seat mounts. The second pair of seat adjustment assemblies may be connected to the stroller frame and may be positioned to translate the second pair of seat mounts along a second linear direction different from the first direction.

[0010] Some implementations relate to a storage basket for a child stroller. The storage basket can include a frame and a basket shell attached to the frame. The basket shell can include fabric that forms side walls and also forms a base of the basket; stiffeners in the fabric that help form the fabric into a basket with a storage volume; and reversible fasteners for fastening and unfastening portions of the basket shell. When the fasteners are fastened, the basket shell supports the frame above the base of the basket, and the basket retains most of the storage volume, and the fabric can collapse against the frame when the fasteners are not fastened.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Current single-to-double strollers typically require the user to reconfigure the stroller from single child-carrying mode to double child-carrying mode by first removing the first child seat, making adjustments to the stroller, adding the first child seat back on top of the stroller, and then adding the second child seat. In many cases, an adapter (which can be visually cluttered) must be added to the stroller before attaching the second child seat. Such strollers lack a way to simply add the second seat onto the mount already present on the stroller frame without having to remove the first child seat. For busy caregivers, each additional step reduces the convenience of using the stroller.

[0015] FIG. 1A shows (in a side elevation view) a stroller system 100 that can be easily converted from carrying one child to carrying two children by adding a second child seat without removing the first. The adapter is already in place on the stroller frame and does not need to be added before attaching the second child seat. Additionally, the stroller system 100 has a clean aesthetic appearance. For example, the seats are arranged in stadium-style seating, with the rear seat elevated above the front seat. This allows for good visibility for both children. The two seats are mounted along one or more portions of the stroller frame that rise from the front wheel mounts 132 to the gripping portion 113 of the stroller handle 110.

[0016] The stroller system 100 (also referred to as a "stroller") includes a stroller frame 105 having a handle 110, at least one front leg 130, and rear legs 140 (only the right rear leg is visible in side view). One or two front wheels 135 may be attached to one or two wheel mounts 132, which in turn are connected to one or two front legs 130. A rear wheel 145 may be attached to each rear leg 140, and there may be rear legs 140 on both the left and right sides of the stroller frame 105. For purposes of illustration, the right side of the stroller frame is the side that is visible in the illustration of FIG. 1A and is the side that a user standing behind the stroller handle 110 and looking toward the front wheels 135 would look to the right. A first child seat 120 may be attached to a first pair of seat mounts 125, which are positioned on the left and right sides of the stroller 100. A perspective view of a portion of the stroller system (with different seating configurations) is shown in Figure 12A.

[0017] The front wheels 135 can swivel to improve the maneuverability of the stroller 100. For example, pivoting the front wheels can enable a turning radius of the stroller as small as the distance D between the center of the rear wheels and the center of the pivot axis of the front wheels. According to some implementations, the distance D can have a value between 23.5 inches and 27 inches. In some cases, the distance D can have a value between 25 inches and 32 inches, while in some implementations, D can be even larger. The front-to-back wheel base (measured between the axles of the front and rear wheels when the front wheels are pivoted for forward movement) can have a value between 22.5 inches and 24.5 inches. In some cases, the front-to-back wheel base can have a value between 23 inches and 30 inches, or even larger, in some implementations. The lateral separation between the centerlines of the rear wheels 145 can be between 25 inches and 27 inches. The front wheels 135 can have the same, smaller, or larger lateral separation compared to the rear wheels 145. The front wheels 135 can have a smaller diameter than the rear wheels 145, as shown. For example, the rear wheels 145 can have an overall diameter of 8 to 12 inches, while the front wheels can have an overall diameter of 6 to 10 inches. In other implementations, the front and rear wheels can have the same overall diameter.

[0018] In some implementations, the front wheels may not swivel, or a swivel lock may be included on each wheel mount 132 to lock its attached front wheel 135 in an orientation for forward movement of the stroller system 100. The stroller may include brakes for one, two, or more of the wheels 135, 145, which may resist and / or prevent rotation of one or more wheels. In some cases, the brakes for one or both of the rear wheels 145 may be operated by a single foot pedal 147. In some cases, a single axle may extend between the two rear wheels 145. Alternatively, each rear wheel 145 may be mounted on a separate axle that attaches separately to the right and left rear legs 140. The tires on the front and / or rear wheels may have tubes or may be tubeless. Tubeless tires may include a solid core (e.g., a resilient foam or rubber core). The latter construction can be used to create a puncture-proof wheel that does not require pressurized air.

[0019] In some implementations, the stroller frame 105 may be formed from a metal material and may include a polymer material. Metals that may be used may include, but are not limited to, steel, stainless steel, aluminum, aluminum alloys, titanium, titanium alloys, brass, etc. Portions of the stroller frame (e.g., the handle 110, front legs 130, and / or rear legs 140) may include, for example, extruded aluminum tubing. Polymers that may be used include, but are not limited to, polypropylene (PP), nylon (PA), and polyoxymethylene (POM, also known as acetal), high-density polyethylene (HDPE), polyvinyl chloride (PVC), and acrylonitrile butadiene styrene (ABS). In some cases, composite materials (e.g., fiber-reinforced polymers, carbon fiber composites, fiberglass, etc.) may additionally or alternatively be used to construct the stroller frame 105.

[0020] In some cases, the stroller frame 105 is foldable for storage, reducing the overall size of the stroller system 100 and the volume occupied by the stroller system 100. To enable folding, the handle 110 is pivotally connected to the rear legs 140 and the front legs 130. Additionally, a link 150 may pivotally connect the front legs 130 and the rear legs 140. The front legs 130 and the handle 110 may be locked in a use position or unlocked for folding.

[0021] As shown in FIG. 1C , folding of the stroller frame 105 can be initiated by an actuator positioned at or near the adjustment knuckle 115 on the stroller handle 110. The folding action can occur in the central region of the stroller between the handle 110 and the front legs 130 (e.g., at or near the rear leg pivot joint 142). In some cases, the folding action can occur just forward of the rear leg pivot joint 142 at the frame hinge 127. Regardless of where the folding occurs, the folding action can lower the handle 110 so that it is parallel or nearly parallel (e.g., within 10 degrees) to the rear legs 140. Additionally, the front legs 130 can be rotated back toward the rear legs 140 so that they are parallel or nearly parallel (e.g., within 30 degrees) to the rear legs 140. In some cases, the handle 110 can be within 15 to 40 degrees of the front legs 130 when the stroller frame is folded. In the folded configuration, the stroller 100 can be self-supporting by some combination of the rear wheels 145, front wheels 135, and stroller gripping portion 113.

[0022] The stroller handle 110 can include several sections extending rearward from the front legs 130. The stroller handle 110 can include a fixed handle portion 114, an adjustable handle portion 112, and a grip portion 113 of the handle 110. The fixed handle portion 114 can extend forward of the adjustment knuckles 115 and can include extruded tubing positioned on the left and right sides of the stroller. In some implementations, the fixed handle portion 114 can connect to a lockable frame hinge 127, which connects to the front legs 130 and can be used to fold the stroller frame 105. The maximum diameter of the tubing used to form the fixed handle portion 114 can be 1 to 2.5 inches, depending on the material used. The tubing can be round or non-round.

[0023] The adjustable handle portion 112 can include a gripping portion 113 and can extend rearward of the adjustment knuckle 115. In some cases, the adjustable handle portion 112 can be formed from a single piece of tubing or extruded tubing that is bent or formed into a generally U-shape (see FIG. 12A ). In some implementations, the adjustable handle portion 112 can be formed from multiple pieces joined together. A height adjustment actuator (e.g., positioned near or at the adjustment knuckle 115) can be used to raise or lower the gripping portion 113 relative to the surface on which the stroller wheels rest. For example, the adjustable handle portion 112 can pivot about the adjustment knuckle 115 and can be locked to fix the height of the gripping portion 113 at two or more different heights H relative to the surface on which the stroller wheels rest. The grip portion 113 may include a cushion (eg, foam, rubber, synthetic leather, or other covering) attached over a portion of the adjustable handle portion 112 .

[0024] The front legs 130 may be formed from metal, polymer, composite material, or some combination thereof. In some implementations, the upper portions of the front legs are formed from extruded tubing, and the lower portions of the front legs are formed from a polymer or composite material. In some cases, the lower portions of the front legs 130 may be coated or covered with a polymer shield. If formed as a joined frame or unitary piece, the front legs may have a U-shape (see FIG. 12A ) and connect to the handle 110 on the left and right sides of the stroller frame 105. For example, a single U-shaped, triangular, or rectangular-shaped front leg 130 may be attached to a frame hinge 127 located on the left and right sides of the stroller frame. In some cases, the stroller may include a pair of front legs 130 and a bar joining the front legs together.

[0025] One or two front wheel mounts 132 may be attached to one or two front legs 130. For example, a single front wheel may be positioned at the underside and center of the front leg 130 when the front legs are formed as a joined frame or unitary piece. When two front wheel mounts are used, they may be attached to the left and right sides of the front leg when the front legs are formed as a joined frame or unitary piece, or they may be attached to separate front legs positioned on the left and right sides of the stroller frame. The wheel mounts 132 may comprise metal, which is welded to the front legs 130 and / or fastened to the front legs 130 by, for example, machine screws. In some cases, the front wheel mounts 132 may be covered by a polymer shield or may be partially formed from a polymer or composite material. The front wheels 135 are each attached to a mounting assembly (e.g., a fork-like mount for holding the wheel and a vertical axle that inserts into the front wheel mount 132) that allows the front wheels to swivel.

[0026] In some implementations, links 150 (one on each side of the stroller) can connect between the front legs 130 and rear legs 140 of the stroller. The links 150 can guide the movement of the front legs 130 and rear legs 140 relative to one another when the stroller frame is transitioned between an unfolded configuration and a folded configuration. In some examples, the links 150 can allow a limited amount of pivoting of the rear legs 140 and absorb some energy when the rear wheels 145 encounter uneven terrain. The links 150 can include springs, gas cylinders, fluid cylinders, elastic materials, or some combination thereof, which absorb, return, and / or dissipate energy. In other implementations, the links 150 may or may not be shock-absorbing. For example, the links 150 can be rigid links. In some such implementations, shock-absorbing components (e.g., springs, gas cylinders, fluid cylinders, elastic materials, or some combination thereof) may be included in the front wheel mounts 132 and / or rear legs 140.

[0027] When the stroller frame 105 is in an unfolded configuration, a significant amount of space 170 may exist between the front legs 130 and the rear legs 140. This space may accommodate at least a portion of an undercarriage basket 160, which may be used to carry items (clothing, groceries, toys, etc.). The basket 160 may include fabric 164, which hangs from a solid frame 162. The frame 162 may be covered (at least partially) by the basket fabric 164. In some cases, the links 150 may be included as part of the basket frame 162, and the basket fabric 164 may extend up to and above the links. In some implementations, one or more stiffeners (e.g., polymer panels, composite panels, etc.) may be used to form the bottom side of the basket 160. For example, stiffeners may be sewn into the fabric 164 that forms the bottom of the basket 160.

[0028] The first child seat 120 may be attached to two adjustable seat mounts 125 located on the left and right sides of the stroller frame 105. Each seat mount 125 may include a receptacle for receiving a mating structure attached to the first child seat 120 and may be translatable relative to the stroller frame 105. In another example, each seat mount 125 may include a bayonet that is received in a receptacle on the child seat. The receptacle of the first seat mount 125 may not rotate or pivot relative to the stroller frame 105. Instead, the first seat mount 125 may be repositioned translationally along the stroller handle 110, for example, in a first linear direction essentially parallel to the central axis of the tubing that forms the fixed handle portion 114. The translation of the first seat mount 125 and the first child seat 120 will be described in further detail below. In some cases, the first seat mount 125 may not translate and may be fixed onto the stroller frame 105.

[0029] For user convenience, the stroller system 100 may further include a cup holder 116 attachable to the stroller frame 105. The cup holder may support any one of a cup, can, bottle, and mug for holding a beverage. The cup holder 116 may be positioned at or near (e.g., within 5 inches of) the adjustment knuckle 115. In some cases, the cup holder 116 may rotate or pivot relative to the stroller frame 105 so that it can rotate or pivot out of the way when the stroller frame 105 is folded and when the handle 110 is folded toward the rear legs 140. The cup holder 116 may be easily attached to and detached from the stroller frame using, for example, a friction fitting on the cup holder 116 and a mating receptacle on the stroller frame 105, although other quick-release structures may also be used (e.g., a snap-on connection, a detent, a fit-in-detent feature, etc.).

[0030] 1B shows the stroller system 100 of FIG. 1A with the first child seat 120 moved to an upper position on the stroller frame 105. The first child seat has been translated from a lower position (in the example of FIG. 1A, in front of the rear leg pivot joint 142) to the rear of the rear leg pivot joint and further up the stroller handle 110. Such translation of the first child seat can induce a closer connection between the stroller user and the child in the first child seat, particularly when the first child seat is facing rearward or when a bassinet or infant car seat is mounted in the first seat mount 125.

[0031] Repositioning and locking of the first seat mount 125 can be controlled by a first seat adjustment handle 118, which is located behind the seat mount and further up the handle 110. The location of the first seat adjustment handles 118 is beneficial for several reasons. First, they allow for repositioning of the first seat mount 125 without having to remove the first child seat 120 or child carrier (and the child) if already attached to the seat mount 125. Additionally, the handles 118 make it easier for a stroller user to reach from the back of the stroller. Furthermore, the user's hands and fingers are always on one side (behind) of the rear leg pivot joint 142, avoiding entanglement with the pivot joint, while the first seat mount 125 can be moved to the opposite side of the rear leg pivot joint 142 (from one side of the pivot joint 142 to the other when moving from the lower position in FIG. 1A to the upper position in FIG. 1B (or vice versa)).

[0032] 2A shows the stroller system 100 of FIG. 1A with a second child seat 220 attached to a second seat mount 225 on the stroller frame 105. For ease of illustration, the first child seat has been removed from the first seat mount 125, but the stroller system 100 is capable of simultaneously accommodating both the first child seat 120 and the second child seat 220. One advantageous feature of the stroller system 100 is that the first child seat 120 (and child) can remain on the stroller frame 105 while the second child seat 220 (and child) is secured to the second seat mount 225. In other words, the second child seat 220 or second child carrying device can be mounted in and removed from the second seat mount 225 without removing the first child seat 120 or first child carrying device mounted in the first seat mount 125. The first child seat 120 or first child carrying device can be mounted in and removed from the first seat mount 125 without removing the second child seat 220 or second child carrying device mounted in the second seat mount 225.

[0033] The second seat mount 225 may be rigidly secured to the stroller frame (e.g., attached via rivets, screws, nuts and bolts, welding, pins, keys, or some combination thereof). In some cases, the second seat mount 225 may be attached to the stroller frame during manufacture of the stroller, or may be attached and removed by the user after manufacture. In this regard, the second seat mount 225 is not an adapter added to attach a second child car seat. Instead, they are a permanent component of the assembled stroller. In some cases, the second seat mount 225 may be removably attached to the stroller frame, allowing the user to easily remove the second seat mount if desired. The second seat mount 225 may also be translatable relative to the stroller frame 105 (e.g., along the same direction as the first seat mount 125 or within 30 degrees of the translation direction of the first seat mount). In some cases, the second seat mount 225 can translate along a second direction that is different from the first direction along which the first seat mount 125 translates. For example, the second seat mount 225 can translate along a second direction 212 or axis that is oblique or perpendicular to the first direction 211 or axis along which the first seat mount 125 translates. The second direction can have an angle ranging from 30 degrees to 90 degrees different from the first direction. In the illustration of FIG. 2A , the second seat mount 225 translates along the second direction 212 or axis that is approximately perpendicular to the first direction 211 or axis along which the first seat mount 125 translates.

[0034] To achieve a compact size, the first seat mount 125 and the second seat mount 225 may be attached to one or more portions of the stroller frame that rise from the front legs 130 to the gripping portion 113 of the stroller handle 110. The portions of the stroller frame to which the seat mounts are attached can be straight or essentially straight, and the adjustment knuckles 115 may be mounted along these same portions of the stroller frame. While these portions (including portions of the front legs and handle) are shown as straight and continuous in FIG. 2A , they can be straight within 10 degrees (e.g., slightly curved, bent, or disjointed within 10 degrees of being parallel to one another).

[0035] When not being used to support the second child seat 220, the second seat mount 225 can translate (at least partially) into the undercarriage space 170 between the front legs 130 and the rear legs 140 or into a storage space in the area below the stroller for storage. In some cases, the second seat mount 225 can translate completely into the undercarriage space between the front legs and the rear legs or into the storage space such that the second seat mount is not visible or is at least partially hidden from view when looking at the side of the stroller, as seen in FIG. 1A. In some cases, the second seat mount can translate into the basket 160 and / or into a fabric pocket formed within or alongside the basket 160.

[0036] Similar to the first seat mount 125 and first child seat 120, the second seat mount 225 and second child seat 220 can be repositioned and locked in two or more positions relative to the stroller frame 105. FIG. 2A shows the stroller system 100 with the second seat mount 225 (and second child seat 220) in the raised position. FIG. 2B shows the stroller system 100 with the second seat mount 225 and second child seat in the lowered position. The raised position can provide better visibility for the second child and can also provide greater separation and improved air circulation between the two children in the first and second child seats. The lowered position can increase intimacy between the two children in the first and second child seats, reduce the overall size of the stroller system for better maneuverability in limited areas, and increase the stability of the stroller system.

[0037] Other child carriers or baskets may be mounted on the first seat mount 125 and the second seat mount 225. Figure 3A shows the stroller system 100 of Figure 1A with an infant car seat 310 mounted on the first seat mount 125 instead of the first child seat 120. In some cases, an infant car seat adapter 320 may be used to adapt each seat mount 125 to the mounting on the infant car seat 310. The infant car seat may be translated along the stroller handle 110 using the first seat adjustment handle 118.

[0038] FIG. 3B shows the stroller system 100 of FIG. 1A with two child carriers mounted on the stroller frame. A first child seat 120 is mounted facing rearward in the first seat mount 125, and a bassinet 330 is mounted in the second seat mount 225. Another example of a child carrier is the bassinet 330 in which a child lies, as shown in FIG. 3B. Either one of the child carrier and the basket can be mounted in the second seat mount 225, while either the child carrier or the basket is mounted in the first seat mount 125. Thus, the stroller system provides a wide variety of configurations of child carriers and baskets.

[0039] Figure 4A shows an example of a first seat adjustment assembly 400 that can be used to reposition and lock the first seat mount 125 to change the position of a car seat or other child-carrying device when mounted in the seat mount. There can be two seat adjustment assemblies, positioned on the left and right sides of the stroller frame 105. Figure 4B shows an exploded view of the first seat adjustment assembly of Figure 4A.

[0040] According to some implementations, the first seat adjustment assembly 400 may include a first seat adjustment handle 118, an adjustment actuator 410, a latch 412, a compression spring 416, and a track follower 420. The handle 110 may include at least one track, and the seat adjustment assembly 400 may include a track follower 420 that engages with the track. Each track may define a protrusion or a recess (i.e., an internal or external track). Each track follower 420 may define another of a protrusion 434 and a recess that engages with a protrusion or recess 436 of the track (see FIG. 4D ). The track and / or track follower may have a T-shaped, triangular, circular cross-section, or may have another shape. The protrusion may have an enlarged portion and a narrowed portion, the narrowed portion having a smaller cross-sectional dimension than the enlarged portion. In a preferred example, the track defines a recess and the track follower defines a protrusion that is received within the recess.

[0041] The seat adjustment handle 118 may be formed from a metal, a polymer, a composite material, or some combination thereof. The first seat mount 125 may be connected to the first seat adjustment handle 118 or may be integrally formed with the first seat adjustment handle 118 and separated from the adjustment actuator by a handle arm 425. The handle arm length may be between 2 inches and 10 inches. The rear portion of the adjustment handle 118 may include a sheath 405 that extends partially or completely around the tubing on which the first seat adjustment assembly 400 is mounted. The seat adjustment handle 118 and first seat mount may be attached to a track follower 420 that helps guide the first seat adjustment assembly 400 along the stroller handle 110.

[0042] FIG. 4C shows a cross-sectional view of a portion of the first seat adjustment assembly 400, showing details of the latching mechanism. The adjustment actuator 410 can protrude through an opening in the seat adjustment handle 118. The inner surface of the adjustment actuator 410 can contact a first end of a latch 412, which is biased outward toward the adjustment actuator 410 by a compression spring 416. When the first end of the latch is biased to the outward position, the opposing latching end 414 of the latch can rotate into and engage a catch 437. The latch 412 can rotate about an axle 422 that is fixed to the track follower 420. The catch 437 can be a slot or hole formed in the tubing of the stroller handle 110. There can be multiple catches 437 positioned along the stroller handle so that the first seat mount 125 can be locked at multiple different locations along the fixed handle portion 114 of the stroller handle 110.

[0043] Depressing the adjustment actuator 410 can rotate the latching end 414 of the latch 412 out of the catch 437, allowing the seat adjustment handle 118 to translate along the stroller handle. In some implementations, the latching end 414 of the latch can include a sloped surface 415 that allows the first seat adjustment handle 118 and first seat mount 125 to be pulled onto the stroller handle 110 without depressing the adjustment actuator 410. Translation of the seat adjustment handle 118 can slide the track follower 420 along the track. In some implementations, a roller bearing or wheel guided by the track or stroller handle can be used instead of a track follower.

[0044] FIG. 4D shows a cross-sectional view of a portion of the first seat adjustment assembly 400 of FIG. 4A , detailing the track 435 inside the handle tubing 430. The handle tubing 430 can form at least a portion of the fixed handle portion 114 of the stroller. According to some implementations, the handle tubing can be extruded aluminum or aluminum alloy tubing, although tubing formed from other materials and by other processes can also be used. The handle tubing 430 can include an interior cavity 432, which is defined as the space within the outermost wall 438 of the handle tubing 430. For the illustrated example of FIG. 4D , the track 435 for the track follower 420 is formed inside the handle tubing. Having the track 435 inside the handle tubing can improve the appearance of the stroller.

[0045] FIG. 4E shows another example of a first seat adjustment assembly 401. In this example, the adjustment actuator 410 is positioned below the stroller's fixed handle portion 114 and seat adjustment handle 118. Such a location may be more ergonomically convenient for the user. The remaining parts of the first seat adjustment assembly 401 may be similar to those of the seat adjustment assembly 400 of FIG. 4A, and their description need not be repeated. Similar to the implementation shown in FIG. 4A, the handle arm 425 may cover the track follower 420 and at least a portion of the track 435 formed in the handle tubing 430, further reducing or eliminating the possibility of fingers getting caught in the track.

[0046] FIG. 4F shows a cross-sectional view of a portion of the first seat adjustment assembly 401 of FIG. 4E , showing details of the latching mechanism. For this implementation, the adjustment actuator is configured to form a lever with mechanical advantage that depresses the first end 411 of the latch 412. For example, the adjustment actuator 410 can pivot about a pin positioned in an arm 417 on either side of the actuator 410. The pin (not visible in the illustration) can extend into a hole in the first seat adjustment handle 118. An internal protrusion 413 can depress the first end 411 of the latch 412, rotating the latching end 414 out of the catch 437, as shown. The lever-type adjustment actuator 410 can provide mechanical advantage and reduce the amount of force required to release the latching end 414 of the latch 412 from the catch 437. A compression spring can bias the latch 412 and actuator 410 into the locked position.

[0047] FIG. 4G shows further details of the first seat mount 125, which may be positioned on the end of the first seat adjustment assembly 400 or assembly 401. The first seat mount 125 may be formed from a metal, a polymer, a composite material, or some combination thereof. The first seat mount may include a seat mount receiver 442 and a catch 444. For the illustrated example, the receiver 442 includes a cavity into which a mating structure may be inserted. The mating structure may be attached to a first child car seat, other child carrying device, or a basket. The mating structure (e.g., an insert as shown in FIG. 6C ) may include a releasable latch that engages with the catch 444 when the first child carrying device or basket is attached, preventing the attached child carrying device or basket from accidentally detaching from the stroller frame 105.

[0048] In other implementations, the first seat mount receiver 442 may not include a cavity, but instead may be formed as an insert (which may be referred to as a bayonet) that can be inserted into a cavity in a mating structure that is attached to the child carrier or basket.

[0049] FIG. 5A shows an example of an infant car seat adapter 500 that can be used to adapt the first and / or second seat mounts 125, 225 to accept one or two infant car seats. The adapter can be formed from a polymer, metal, composite material, or some combination thereof. The adapter 500 can include a seat mount structure 510 and an infant car seat structure 520, as well as a support portion 515 connecting the seat mount structure 510 and the infant car seat structure 520. For the example shown, the seat mount structure 510 includes an insert with an adapter latch 530, and the infant car seat structure 520 also includes an insert. Each of the two inserts can be inserted into a cavity over the respective receptacles of the first seat mount 125 and the infant car seat 310 (see FIG. 3A), for example. In an alternative implementation, one or both of the seat mount structure 510 and the infant car seat structure 520, instead of being formed as an insert, can include a cavity for receiving an insert.

[0050] FIG. 5B shows the infant car seat adapter 500 of FIG. 5A mounted in the first seat mount 125 of FIG. 4G. The adapter latch 530 engages with the catch 444 of the first seat mount 125, preventing accidental release of the adapter from the seat mount. An actuator on the same or opposite side of the adapter 500 can be used to release the latch. Examples of actuators are described below in connection with FIGS. 11B and 11C. To increase the strength and stability of the infant car seat 310, the adapter can include supports 515 that extend along the edges of the seat mount 125. The supports 515 can also allow the infant car seat structure 520 to be positioned off-center in the seat mount structure 510 (e.g., to move the infant car seat closer to the stroller user). In some cases, the support 515 can include a recess 517 for receiving a plunger from an infant car seat mounting assembly when mounted on the adapter 500. The plunger can lock the infant car seat to the adapter 500. In some cases, the infant car seat structure 520 can be centered above the seat mount structure 510 and the support 515 can not be included.

[0051] FIG. 6A shows an example of a second seat adjustment assembly 600 that can be used to mount a second child carrier or basket to the stroller frame 105. FIG. 6B shows the track follower 620 and armature 615 of the second seat adjustment assembly of FIG. 6A separately. The second seat adjustment assembly 600 can include a second seat mount 225, an adjustment actuator 610, an armature 615, and a track follower 620. The track follower can be attached to a mounting plate 138, which is fixedly attached to the front leg 130 of the stroller. For example, the mounting plate 138 can be welded, screwed, or riveted to the front leg 130, and the track follower can be welded, screwed, or riveted to the mounting plate. The track follower 620 may be formed from a metal, a polymer, a composite material, or some combination thereof, and may include a groove 622 that engages and guides the rail 612 on the armature 615, allowing the armature to slide along the track follower. In other implementations, roller bearings or rollers may be used in place of the rail 612 to translate the armature 615 and second seat mount 225 relative to the track follower 620.

[0052] The armature 615 may be formed from a polymer, metal, composite material, or a combination thereof. In some cases, the second seat mount 225 may be integrally formed with the armature 615 (e.g., molded or cast as a single piece). In other cases, the second seat mount may be attached to the armature 615 (e.g., by welding, rivets, and / or screws). The armature 615 may include a plurality of detents or catches on its inner surface between the rails 612 that receive latches 624 on the track followers 620 to lock the position of the armature relative to the track followers 620 in any one of a number of different locations. One of the locations may be a storage location, allowing the second seat mount 225 to be partially or fully retracted into the space 170 (e.g., into the basket 160) in the front and rear legs 130 and 140 of the stroller.

[0053] The latch 624 can be part of a bending cantilever beam that is formed with a groove 626 into the track follower and is formed by removing material of the track follower below the latch 624 and groove 626. The adjustment actuator 610 can raise an array of pins in a detent or catch on the armature 615, or a rod or bar that runs across the detent or catch, ejecting the latch 624 from the detent or catch and allowing translation of the armature 615 relative to the track follower 620.

[0054] Figures 6C and 6D show an example of a second seat adjustment assembly 601 that provides automatic orientation selection for a second child seat or child carrier. Figure 6D shows an exploded view of the second seat adjustment assembly 601. The illustration in Figure 6C also shows a portion of the second child seat 220 being inserted into the second seat mount 225.

[0055] The second seat adjustment assembly 601 can include a directional lever 640 that automatically toggles between two or more positions as the armature 615 is adjusted along the track follower 620. The toggled position of the directional lever 640 can determine which orientations of the second child seat 220 are allowed. There can be only one directional lever 640 in one seat mount 225 of a pair of seat mounts, or directional levers can be included in both seat mounts of a pair. In some cases, restricting the orientation of the second child seat and / or the first child seat with such a directional lever can improve the stability and / or handling of the stroller system 100.

[0056] The second seat adjustment assembly 601 can include a second seat mount 225, an adjustment actuator 610, a compression spring 614, a directional lever 640, a torsion spring 642, an armature 615, a cover 616, and a track follower 620. The track follower can be attached to a mounting plate 138, which is fixedly attached to the front leg 130 of the stroller. The track follower 620 and the armature 615 can be formed from a metal, a polymer, a composite material, or some combination thereof. The track follower 620 can include a groove 622 that engages and guides a rail 612 on the armature 615, allowing the armature to slide along the track follower. In other implementations, roller bearings or rollers can be used in place of the rail 612 to translate the armature 615 and the second seat mount 225 relative to the track follower 620.

[0057] FIG. 6D illustrates the second seat mount 225 integrally formed with the armature 615 (e.g., molded or cast as a single piece, as shown in FIG. 6D ). In other cases, the second seat mount may be attached to the armature 615 (e.g., by welding, rivets, and / or screws). The seat mount 225 may be positioned directly above the track follower 620 when assembled, providing a slim profile such that the combined thickness of the seat mount 225, armature 615, and track follower 620 does not exceed 20 mm. For the implementation of FIG. 6D , the track follower 620 includes multiple detents 623 for receiving the latching protrusions 611 of the adjustment actuator 610 to lock the position of the armature 615 relative to the track follower 620. In some cases, when the second seat mount 225 is partially or fully retracted into the space 170 between the front legs 130 and rear legs 140 of the stroller (e.g., into the basket 160), the latching protrusion 611 may not engage with the detent in the track follower 620.

[0058] To achieve automatic orientation selection, the directional lever 640 can interact with features on the second child carrier. For example, referring to FIG. 6C , the seat hub 920 on the second child carrier can include a seat hub insert 922 having one or more insert recesses 925. The insert recesses can accommodate the directional lever 640 when the directional lever 640 is toggled between two or more positions. For the case illustrated in FIG. 6C , the insert recess 925 is shaped to accommodate the directional lever 640 in two positions (tilted toward the rear of the stroller as shown, or tilted forward, provided the child carrier is properly oriented). When tilted backward as shown in FIG. 6C , the insert recess 925 allows the second child carrier to be mounted in only one orientation (e.g., the child facing rearward in the car seat). Such an orientation can be allowed when the second seat mount 225 is positioned at one or more rearward locations along the track follower 620. When the directional lever 640 is tilted forward, it may not allow the second child seat 220 to be installed so that the child is facing rearward, for example. Instead, the second child seat 220 must be rotated 180 degrees to be installed, moving the center of mass of the second child toward the rear of the stroller system 100. This orientation may improve the stability and / or maneuverability of the stroller system.

[0059] Figure 6E is a cross-sectional view of the second seat adjustment assembly 601 of Figure 6C. This illustration shows details of the directional lever in the second seat mount 225 in a first position (tilted rearward). When the second seat mount assembly 601 is in one or more rearward positions, the foot 645 of the directional lever 640 engages the track follower 620 and can rotate the directional lever 640 to the rearward position against the torsion spring 642. When the second seat mount assembly 601 is in one or more forward positions, the foot 645 of the directional lever 640 can disengage from the track follower 620, allowing the torsion spring 642 to rotate the directional lever 640 to the forward position, as shown in Figure 6F.

[0060] In some cases, the directional lever 640 can be toggled to a third orientation, which is a neutral orientation. Instead of rotating to a forward position as in FIG. 6F , the directional lever can be rotated to a neutral orientation. The neutral orientation can be an orientation in which the directional lever 640 lies along the axis of symmetry of the second seat mount 225 (e.g., vertically aligned straight up and down at the center of the second seat mount 225). In such cases, the insert recess can extend to the center of the seat hub insert 922, or an additional recess can be added to the center of the seat hub insert. The neutral orientation can allow the second child seat to be installed in both forward-facing and rearward-facing orientations. To avoid interference with any latching mechanisms on the seat hub insert 922 (e.g., latch 530 and catch 444 in FIG. 5B ), the directional lever 640 can be shortened or positioned on the opposite side of the second seat mount 225 from the latching mechanisms.

[0061] FIG. 6G shows a cross-sectional view of a portion of the second seat adjustment assembly 601 of FIG. 6C , detailing the adjustment actuator 610 and its latching protrusion 611 in a locked position. When positioned over a detent 623 in the track follower 620, a compression spring 614 can urge the latching protrusion 611 of the adjustment actuator 610 into the detent 623 or catch, locking the position of the armature 615 and second seat mount 225 relative to the track follower 620. Pressing the adjustment actuator 610 can rotate the actuator 610 about a fulcrum 613 formed in the adjustment actuator 610, lifting the latching protrusion 611 out of the detent 623 into an unlocked orientation, as shown in FIG. 6H . The fulcrum 613 can pivot on a surface of the armature 615.

[0062] 7A-7C show details of the adjustment knuckle 115, which may integrate a first actuator for folding the stroller frame 105 and a second actuator for adjusting the height of the adjustable handle portion 112 and the grip portion 113. The adjustment knuckle may provide a hinge or pivot function for the adjustable handle portion 112 relative to the fixed handle portion 114. The stroller may have one adjustment knuckle located on one side of the stroller frame (e.g., at the junction between the adjustable handle portion 112 and the fixed handle portion 114). In some cases, the stroller may have two adjustment knuckles, one located on the left side of the stroller frame and one located on the right side of the stroller frame. FIG. 7B is an exploded view of the adjustment knuckle of FIG. 7A, and FIG. 7C is a cross-sectional view showing further details of the adjustment knuckle of FIG. 7A.

[0063] The adjustment knuckle 115 can include a fold trigger 712 and a height adjustment actuator button 730, as shown in FIG. 7A. The fold trigger 712 can be pulled by a user to actuate the folding of the stroller frame 105. The height adjustment actuator button 730 can be pressed or depressed to enable pivoting (and height adjustment) of the adjustable handle portion 112 relative to the fixed handle portion 114. Pivoting of the adjustable handle portion 112 can raise and lower the grip portion 113 of the stroller handle 110 (see FIG. 1A).

[0064] Components of the adjustment knuckle 115, height adjustment actuator, and fold actuator are shown in FIG. 7B. Additional components of the adjustment knuckle 115 can include a first knuckle housing 740, a sliding gear 732, a compression spring 734, a second knuckle housing 750, and a cover 755. The fold trigger actuator 710, the first knuckle housing 740, the sliding gear 732, the second knuckle housing 750, and the cover 755 can each be formed from a metal, a polymer, a composite material, or a combination thereof. The height adjustment actuator can include a height adjustment button 730, a sliding gear 732, a compression spring 734, and teeth 736 formed on an interior portion of the adjustment knuckle. The fold actuator can include a fold trigger actuator 710, a fold trigger 712, a cable catch 714, a roller 722, and a cable 720.

[0065] A screw or shaft (not shown in FIG. 7B ) can run centrally through the folding trigger actuator 710 (on which the folding trigger 712 can be formed), the second knuckle housing 750, the sliding gear 732, and the first knuckle housing 740 to hold the components together and allow rotation or pivoting of the first knuckle housing 740 relative to the second knuckle housing 750. A first knuckle housing extension 742 can secure the first knuckle housing 740 to the adjustable handle portion 112, and a second knuckle housing extension 752 can secure the second knuckle housing 750 to the fixed handle portion 114.

[0066] The interior of first knuckle housing 740 and second knuckle housing 750 can each have teeth 736 formed therein that engage with teeth on sliding gear 732. Sliding gear 732 can be movable (toward the left and right sides of the stroller) inside a cavity formed by first knuckle housing 740 and second knuckle housing 750. A compression spring 734 can be positioned within the cavity and bias sliding gear 732 into a position where the teeth of sliding gear 732 engage with the formed teeth of both first knuckle housing 740 and second knuckle housing 750, thereby locking the position of first knuckle housing 740 and adjustable handle portion 112 relative to second knuckle housing 750 and fixed handle portion 114. When the height adjustment actuator button 730 is depressed, a leg or other protrusion 731 on the actuator can push against a compression spring 734 to disengage the teeth on the sliding gear 732 from engagement with the teeth 736 formed inside the first knuckle housing 740. This release of the engaged teeth can allow the first knuckle housing 740 and the adjustable handle portion 112 to pivot to different orientations relative to the second knuckle housing 750 and the fixed handle portion 114. Releasing the height adjustment actuator button 730 can re-engage the teeth on the sliding gear 732 with the teeth 736 formed inside the first knuckle housing 740, thereby locking the orientation of the adjustable handle portion 112. The use of the sliding gear 732 as shown can allow the adjustment knuckle 115 to be compact and narrow along the stroller frame (e.g., no more than 1.5 times the width of the fixed handle portion 114).

[0067] The second knuckle housing 750 can include a roller 722, over which the cable 720 can translate. The roller 722 and at least a portion of the cable 720 can be positioned under a cover 755 when the adjustment knuckle 115 is assembled. An end of the cable 720 can be attached to a cable catch 714 positioned on the fold trigger actuator 710. For example, the cable pin 724 can be inserted into the cable catch 714, as shown in FIG. 7C . When the fold trigger 712 is pulled, the fold trigger actuator 710 can rotate and pull the cable 720. The cable can connect to a mechanism to unlock the frame hinge 127, allowing the stroller frame 105 to fold. In this manner, the fold trigger 712 can be neatly and compactly integrated with the adjustment knuckle 115 by each using the same pivot axis.

[0068] 7D shows an example of a sliding gear 732 that may be used in the adjusting knuckle of FIG. 7A or 7E. The sliding gear may be formed from a metal, such as brass, aluminum, or stainless steel, although other metals may also be used. In some implementations, the sliding gear 732 may additionally or alternatively be formed from a polymer or composite material. The sliding gear 732 may include teeth on its periphery and / or on one or both sidewalls 733 of the sliding gear.

[0069] FIG. 7E shows another example of an adjustment knuckle 701 that integrates two actuators for handle height adjustment and folding of the stroller frame. The example shown includes a cup holder mount 810 that is integrated with the adjustment knuckle 701. For example, the cup holder mount 810 can be formed (cast, machined, or molded) from the same material and as part of the component of the adjustment knuckle 701. For example, the cup holder mount 810 can be formed as part of the first knuckle housing 740, the second knuckle housing 750, or the cover 755 for the implementation of FIG. 7A or 7E. The integration of the folding actuator and the height adjustment actuator into the adjustment knuckle can allow the cup holder mount 810 to be positioned closer to the knuckle and in a more convenient location closer to the user instead of being positioned farther below the stroller frame. A cup holder 820 (shown in FIG. 8) for holding a cup, can, or bottle can slide or snap onto the cup holder mount 810 or can be otherwise retained on the cup holder mount 810.

[0070] FIG. 7F is an exploded view of the adjusting knuckle 701 of FIG. 7E. Similar components present in the implementation of FIG. 7B are labeled with the same reference numerals and will not be described again. For this implementation, the cup holder mount 810 is integrally formed with the cover 755 as a single piece. The cover 755 and cup holder mount 810 may be attached to (e.g., snapped onto) the second knuckle housing 750. The cable lever 723 and lever catch 715 may be positioned inside the cover 755 when the adjusting knuckle 701 is assembled, and it is also possible that a roller for the cable 720 is not used.

[0071] FIG. 7G is a cross-sectional view showing further details of the adjustment knuckle of FIG. 7E, illustrating the operation of cable lever 723. When folding trigger 712 is pulled, folding trigger actuator 710 rotates, and lever catch 715 engages and pulls the end of cable lever 723. This pulling action rotates cable lever 723 about fulcrum 725, which causes cable lever 723 to pull cable 720. The use of cable lever 723 can eliminate the need for a roller and its axle, and can be actuated with less force.

[0072] FIG. 8 shows an example of a cup holder assembly 800 that can be mounted near or attached to the adjustment knuckle of FIG. 7A. In some cases, the cup holder assembly can be formed as a separate component that can be attached to and detached from the stroller frame 105 by a user. The cup holder assembly 800 can include a cup holder mount 810 that can extend at least partially around a portion of the fixed handle portion 114 of the stroller and can further extend over at least a portion of the adjustment knuckle 115. A cup holder 820 for holding a cup, can, or bottle can be attached to the cup holder mount 810. The cup holder mount 810 and / or the cup holder 820 can be formed from a polymer, a composite material, or some combination thereof. In some cases, the cup holder mount 810 can rotate about an axis 815 that runs transverse to a direction along the fixed handle portion 114. Such rotation can allow the cup holder 820 to rotate when the stroller frame is folded, allowing the stroller frame to achieve a more compact size when folded (e.g., rotate out of the way so that the stroller handle 110 can be folded closer to the rear legs 140).

[0073] 9A shows an example of a child seat frame 910 that may be included in a first child seat 120 and / or a second child seat that can be attached to a stroller frame 105. The first and / or second child seats may or may not be packaged with the stroller frame 105 when made available to consumers. For example, one or more child seats, bassinets, baskets, infant car seats may be purchased separately and subsequently attached onto the stroller frame 105 for the stroller system 100, as shown in FIGS. 1A-3B.

[0074] The child seat frame 910 may be formed (at least in part) from tubing that is formed into a hoop. The tubing can be extruded metal tubing or may be formed from a composite material. The hoop may be assembled from two or more pieces of tubing. The frame 910 may include one or more crossbars 930 to provide additional strength to the frame and to provide a structure to which seating for a child may be attached or supported. The child seat frame 910 may further include a seat hub 920 (with a seat hub insert 922 and a release actuator 925) and a seat tilt actuator 940.

[0075] 9B shows an example of a child seat frame 910 including a leg pan 950 with a footrest 952. The leg pan and footrest may be formed from a polymer, a composite material, or a combination thereof and may be attached to tubing in the seat frame 910. In some cases, the leg pan 950 and footrest 952 may replace metal tubing in the lower portion of the seat frame 910. In other cases, the leg pan and footrest may extend over metal tubing in the lower portion of the seat frame 910. The leg pan and footrest may provide a rigid, durable structure to more comfortably support a child's legs and feet.

[0076] FIG. 9C shows further details of an exemplary leg pan for the child seat implementation of FIG. 9B . The leg pan 950 extends over the crossbar 930 and can include a flange 956 on the rear side of the leg pan. The flange 956 can include anchor fastening holes 957 for attaching the child seating thereto. The leg pan 950 can also include crossbar holes 955 where the leg pan extends over the crossbar 930. The crossbar holes 955 can be used to secure the leg pan 950 to the crossbar 930 (e.g., with rivets, screws, snaps, or other fasteners). The leg pan 950 can also include one or more fastener anchors 954 in a lower portion of the leg pan. The fastener anchors 954 can receive screws, snaps, or other fasteners attached to the fabric of the child seating.

[0077] Figure 9D shows an example of a child seat 120 with child seating 915 attached to the child seat frame 910. Figure 9E is a cross-sectional view of the seating apparatus of Figure 9D. The child seating may be made (at least in part) from fabric. The child seating 915 may be attached to and detached from the seat frame 910 by a user so that the fabric can be easily washed, for example in a conventional washing machine.

[0078] While some stroller seats may have removable fabric, these seats typically include stiffeners that can hinder or make it impossible to wash and machine dry the fabric in a conventional washing machine. The car seat of the present invention has removable stiffeners that allow the fabric to be washed and machine dried in a conventional washing machine.

[0079] The child seating 915 may include a fabric seat backing 980, a backboard 970, fabric side panels 985, and a seat board 960. The backboard and seat board may include a rigid material (e.g., a polymer, a composite material, fiberboard, or a board composite material, or some combination thereof). In some cases, the seat board 960 and backboard 970 may be covered with fabric and / or foam material for protection and / or cushioning. The backboard 970 may be inserted into a seat back pocket 984 formed by the fabric of the child seating 915, as shown in FIG. 9E. The seat board 960 may be inserted into a seat board pocket 986 formed by the fabric of the child seating 915. Fasteners 990 (e.g., snaps, pins, hook-and-loop pads, etc.) may be used to secure the seat board 960 and / or backboard 970 in their respective pockets.

[0080] Also, a seat frame pocket 982 may be formed by the fabric of the child seating. The seat frame pocket 982 may extend around at least a portion of the seat frame 910. There may be snaps, hook-and-loop pads, or other fasteners that secure the fabric of the seat frame pocket 982 around and / or to the seat frame 910.

[0081] The child seating 915 may also include safety straps to prevent a child from accidentally falling out of the child seat 120. The safety straps may include shoulder straps 977, waist straps 973, and inter-leg straps 962. The straps may have adjustable lengths, and their ends may be attached to the child seating fabric. In some cases, the straps may pass through openings (e.g., buttonholes) in the fabric of the child seating 915 and may be attached to the seat board 960 and / or backboard 970. The safety straps may be formed from a woven material (e.g., nylon or polyester).

[0082] FIG. 10A shows an example of a collapsible and adjustable canopy 122 that attaches to the child seat frame 910 of FIG. 9B. In FIG. 10A, the canopy 122 is adjusted to a lower position on the frame 910, above the seat hub 920. The canopy can include a canopy hub 1010, a rotatable bow 1030, a fixed bow 1032, one or more stiffeners 1034, and fabric 1015. The rotatable bow 1030, the fixed bow 1032, and the one or more stiffeners 1034 can be formed from metal, polymer, composite material, or combinations thereof, and can be formed as flexible wire, straps, tubes, or the like. The rotatable bow 1030 and the fixed bow 1032 can connect to the canopy hub 1010 and provide a rigid connection to the child seat frame 910. FIG. 10B shows an example of the canopy 122 of FIG. 10A adjusted to an upper position along the child seat frame 910 of FIG. 9B.

[0083] The canopy hub 1010 may be configured to translate along the child seat frame 910, allowing a user to adjust the location of the canopy 122 on the frame 910 to two or more different positions, as shown in Figures 10A and 10B. Canopy translation can be convenient because it allows the canopy 122 to be repositioned and positioned properly for children of different heights. Translation can also allow for height adjustment for the same child seat as a child grows.

[0084] FIG. 10C shows an example of a canopy hub 1010 that can allow translation of the canopy 122 and further allow collapse of the canopy fabric 1015. There can be a first canopy hub 1010 on the left side of the seat frame 910 and a second canopy hub 1010 on the right side of the seat frame. The canopy hub 1010 can include a translating mount 1016, a pivoting hub 1012, and a pivoting arm 1014. The translating mount, pivoting hub, and pivoting arm can be formed from a metal, a polymer, a composite material, or some combination thereof. The pivoting hub 1012 and the pivoting arm 1014 can rotate relative to the translating mount 1016. A fixed bow 1032 can be attached to the translating mount 1016. A rotatable bow 1030 can be attached to the pivoting arm 1014. Rotating the rotatable bow 1030 and pivot arm 1014 forward (e.g., about an axis 1011 running laterally of the stroller) can raise the canopy 122 and deploy its fabric 1015 to a taut condition. Rotating the rotatable bow 1030 and pivot arm 1014 backward can retract the canopy 122 and collapse its fabric 1015 behind the stroller. Figure 10C shows the rotatable bow 1030 and pivot arm 1014 in a collapsed position. The fabric is not shown in Figure 10C to simplify the drawing.

[0085] Figure 10D shows a cross section of a portion of the canopy hub 1010 of Figure 10C. The translatable mount 1016 can extend all or partly around the tubing of the seat frame 910. The track 1020 can be mounted on or formed as part of the seat frame 910. The track can include two or more recesses 1022. The translatable mount 1016 can include a latch 1017, which can be formed as a bent finger having a protrusion 1018. The protrusion 1018 can engage the recess 1022 in the track 1020 to hold the canopy hub 1010 and canopy 122 in two or more positions along the seat frame 910.

[0086] 9A and 1A, the child seat frame 910 and child seat or other child-carrying device may be secured to the stroller frame's seat mount 125, 225 by a seat hub 920. FIG. 11A is a perspective view showing an example of a portion of the seat hub 920 inserted into the receptacle of the seat mount 125. FIG. 11B is a cross-sectional view of the seat hub of FIG. 11A illustrating the locked configuration. The seat hub may include a seat hub body 1110, a seat hub insert 922 (inserted into the seat mount receptacle of FIG. 11A), and a release actuator 925. The seat hub 920 may provide functionality for securely attaching and detaching the child seat 120 to the stroller frame 105, as well as for rotating the child seat (changing the inclination of the child seat) relative to the stroller frame.

[0087] In some cases, the seat hub insert 922 may be formed as part of the seat hub body 1110 (e.g., from the same material in the same molding or casting process). The seat hub insert 922 may include a latch 1130 that engages with a catch 444 formed in a receptacle of the seat mount 125. A compression spring 1134 may be included in the seat hub insert 922 and bias the latch 1130 into a locked orientation. In the locked orientation, the latch 1130 may secure the seat hub 920 and car seat, child carrier, or basket to the stroller frame, preventing it from accidentally disengaging from the stroller frame. To achieve a slim profile for the insert 922, the latch 1130 may be retracted using an angled guide 1122 (e.g., a groove, ridge, or track) formed in a portion of the release actuator 925. The release actuator can have a body portion 1120 that includes finger recesses 1125 that allow fingers to engage an upper portion of the actuator 925. The seat hub body portion 1110, the seat hub insert 920, and the release actuator body portion 1120 can be formed from a metal, a polymer, a composite material, or a combination thereof.

[0088] 11C is a cross-sectional view of the seat hub 920 illustrating the unlocked configuration. By pulling the seat release actuator 925 upward, the angled guide 1122 can engage mating structure on the latch and retract the latch 1130 inward. Retraction of the latch 1130 allows the seat hub insert 922 to be removed from the receptacle in the seat mount 125.

[0089] The seat hub 920 can also include a rotation plate 1140 (shown in FIGS. 11D and 11F) and a recliner assembly 1150 (shown in FIGS. 11E and 11F). The rotation plate can be mounted within a rotation plate recess 1112 in the seat hub body 1110 (see FIG. 11A) or can be otherwise attached to the seat hub body 1110. When mounted within a recess, the recess 1112 can include formed teeth 1114, pins, protrusions, or other structures that mate with plate mounting detents 1144, holes, recesses, or other mating features formed in the rotation plate 1140 to prevent the rotation plate 1140 from rotating relative to the seat hub body 1110. Alternatively, the rotation plate can be secured within the seat hub body 1110 with pins, screws, or rivets. The pivot plate 1140 may be formed from a strong, durable material (such as, for example, a metal or composite) so that it can withstand the load stresses associated with supporting and rotating a child car seat when transporting a child. As shown in FIG. 11B, by using a strong, durable pivot plate 1140 and seat release actuator 925 and latch assembly, the seat hub 920 can be narrow (e.g., no wider than 20 mm).

[0090] The rotating plate 1140 can include a plurality of recline detents 1146 or slots that are used to lock the reclined orientation of the child seat 120 relative to the stroller frame. The rotating plate can also include holes at the pivot axis 1142 through which a screw, shaft, or pin can be inserted. The pivot axis 1142 can be the axis about which the recliner assembly 1150 rotates. In some cases, pairs of detents or slots can be diametrically opposed from the pivot axis 1142 to provide additional strength to secure the reclining of the child seat.

[0091] FIG. 11E shows an example recliner assembly 1150 that may be included within the seat hub 920 in a partially exploded view. The recliner assembly may include a first cover 1152, a second cover 1154, a pivot plate 1160, a pin carrier 1162, and a compression spring 1164. The first cover, the second cover, and the pin carrier may be formed from a metal, a polymer, a composite material, or a combination thereof. The pin carrier 1162 may carry one or more pins 1166 that extend through holes in the pin carrier. The compression spring 1164 may be positioned to bias the pin carrier 1162 into the locked position. The pivot plate 1160 may be formed from a strong, durable material (e.g., a metal or a composite material).

[0092] The first cover 1152 can include a first insert 1155 that can be inserted into the tubing of the child seat frame 910. The second cover 1154 can include a second insert 1156 that can be inserted into the tubing of the child seat frame or into a receptacle on the child seat frame. A pivot plate 1160 can be sandwiched between the first cover 1152 and the second cover 1154, and the assembly can be held together with screws or rivets that extend through holes in the first cover, the pivot plate, and the second cover. The pivot plate 1160 can have arms that run parallel to the first and second inserts and extend into the tubing of the child seat frame 910 to provide additional strength when joining the portions of the seat frame 910 together. In some cases, the recliner assembly may be attached to the seat frame 910 by screws, rivets, other fasteners, or welding. When assembled together and attached to the seat frame 910, the pivot plate 1160 and the recliner assembly 1150 can have a fixed orientation relative to the seat frame.

[0093] The first cover 1152 can also include an opening 1158 into which the rotation plate 1140 and at least a portion of the seat hub body 1110 can fit. In some implementations, a groove 1116 or tongue (see FIG. 11A ) can extend around at least a portion of the rotation plate recess 1112, which mates with a tongue 1118 (see FIG. 11G ) or groove that extends around at least a portion of the opening 1158. The mating tongue and groove can guide or help guide the rotation of the recline assembly 1150 relative to the seat hub body 1110.

[0094] FIG. 11F shows another view of the recliner assembly 1150 of FIG. 11E in an unlocked configuration with the first cover 1152 removed. FIG. 11G shows a cross-sectional view of the recliner assembly 1150 of FIG. 11E with the first cover 1152 in place. FIG. 11H shows further details of the pivot plate 1160, pin carrier 1162, and pin 1166, which may be used in the recliner assembly 1150 of FIG. 11E. These three illustrations can aid in understanding how the recliner assembly 1150 and child seat 120 rotate and lock relative to the seat hub body 1110 and stroller frame 105. Rotation of the recliner assembly 1150 changes the tilt angle of the seat frame 910 and child seat 120.

[0095] When the seat hub body 1110, rotating plate 1140, pivot plate 1160, and recliner assembly 1150 are assembled into the seat hub 920, the orientation of the recliner assembly can be locked relative to the seat hub body by one or more pins 1166 that extend through the pivot plate 1160 and into the rotating plate 1140. The one or more pins 1166 can extend through openings 1165 in the pivot plate 1160 and engage one or more recliner detents 1146 in the rotating plate 1140, locking the pivot plate 1160 relative to the rotating plate 1140. There can be multiple recliner detents 1146 in the rotating plate 1140, which may or may not be spaced equally apart.

[0096] To change the tilt of the child seat 120, the pin carrier 1162 can be translated to move the pin from the recline detent 1146 to an unlocked configuration, which is shown in FIG. 11F. In the unlocked configuration, the pivot plate 1160 and child seat 120 can be rotated about the rotating plate 1140 and seat hub body 1110 to a different orientation, which can be locked in the new orientation by the pin 1166 and detent 1146.

[0097] In some implementations, the pin carrier 1162 may be translated within the recliner assembly 1150 by a cable or wire (not shown) that pulls the pin carrier 1162 against a compression spring 1164 (see FIG. 11G). The cable may run through the recliner assembly and may run through or along the tubing of the seat frame 910 to the seat recliner actuator 940 ( FIG. 9A ). Moving the seat recliner actuator 940 may tension the cable, causing it to pull the pin carrier 1162. The wire or cable may run from the recliner actuator 940 to the pin carriers in the left and right seat hubs 920.

[0098] As described above, the stroller system 100 can accommodate one or two child seats, infant car seats, bassinets, or a combination of any two of the above-mentioned child carriers. However, the stroller system is not limited to child carriers only. The stroller system 100 can also accommodate one or two auxiliary baskets 1200, an example of which is shown in FIG. 12A. The baskets can be mounted in place of the first and / or second child seats. In FIG. 12A, the child seat 120 is mounted in the second child seat position, and the basket 1200 is mounted in the first child seat position.

[0099] FIG. 12B illustrates further details of the auxiliary basket 1200 of FIG. 12A. The basket 1200 can include a frame 1210, and a basket shell 1220 can be attached to the frame 1210. The frame 1210 can be formed from a metal, a polymer, a composite material, or some combination thereof. The shell 1220 can be formed from a fabric, a polymer, a composite material, or some combination thereof. The basket can have a base 1203 and side walls 1222, which define the basket's storage volume 1205 when unfolded for use. The basket's storage volume 1205 can be between 1 cubic foot and 5 cubic feet. In some cases, stiffeners can be used in at least two of the shell's side walls 1222 to allow the basket 1200 to stand on its base 1203 when placed on a flat surface and when removed from the stroller frame 105. Such freestanding functionality can be convenient for loading and unloading the basket when not attached to a stroller. Additionally or alternatively, the shell 1220 may be collapsible relative to the frame 1210 so that the basket 1200 can be stored in a flattened configuration.

[0100] In some cases, the basket 1200 can include handles 1230 on opposite sides of the basket. The handles 1230 can include a portion of the frame 1210 and a cutout in the basket shell 1220. The seat mount adapters 1240 can be interchangeably attached to and detached from the frame 1210. In some implementations, each seat mount adapter can be attached to and detached from a track 1250 attached to the basket frame 1210. The track 1250 can allow the basket 1200 to translate to different lockable positions relative to the stroller frame 105. The seat mount adapters 1240 can be packaged with the basket 1200 when commercially available or can be provided separately from the basket 1200. Seat mount adapters for use with the basket can have different designs and can allow the basket to be attached to different types of seat mounts on different strollers.

[0101] Figure 12C is an exploded view of the auxiliary basket 1200 of Figure 12A. The frame 1210 may be formed as two or more sections 1211, 1212 of tubing (e.g., extruded tubing) joined together by a coupler 1235. The coupler 1235 can form a handle for the basket and may be covered (at least partially) by a soft material (e.g., foam, cloth, or imitation leather, etc.).

[0102] 12D shows an example of attachment of a basket shell 1220 to a basket frame 1210 for the auxiliary basket of FIG. 12B. In some cases, the side walls 1222 of the basket shell can extend through slots 1215 in the basket frame 1210. Beading (not shown) along the edges of the basket shell 1222 can hold the shell in the slot. In some implementations, an internal channel or tube wall 1217 is formed as part of the basket frame 1210 to strengthen the frame and resist separation of the slots 1215 due to heavy loads within the basket 1200.

[0103] 12E illustrates an example of a beading 1226 that can help support the basket shell 1220 within the basket frame 1210. The beading can be formed from a fibrous cord (e.g., rope, etc.). Alternatively, the beading can be a rod or tube formed from, for example, a polymer or composite material. The beading can be inserted into a sleeve 1224 formed along the edge of the basket shell 1220.

[0104] Figure 12F illustrates the basket shell 1220 of Figure 12B in a collapsed configuration. While shown unattached to the basket frame 1210, the shell 1220 can collapse in the same manner when attached to the basket frame 1210. In some cases, the basket 1200 when collapsed can stand no higher than 1.1 times the height of the basket frame 1210 (e.g., no more than 10% taller than the basket frame 1210 without the shell 1220). When uncollapsed, the same shell can provide sufficient strength for the basket to stand on its base 1203 and retain most of its storage volume 1205.

[0105] To collapse the basket shell and further maintain the freestanding characteristics of the basket 1200, the basket shell 1220 can include stiffeners and flaps or panels that form part of the basket shell 1220. The stiffeners can be polymer or composite boards, straps, rods, or tubing attached to the flaps or panels of the shell 1220. FIG. 12G illustrates overlapping and fastening flaps 1227 that can be used to form the shell of the auxiliary basket 1200. In some cases, there can be one or more flaps 1227 or panels formed from fabric containing one or more stiffeners. The flaps can include one or more fasteners 1228 along one or more edges of the flaps. Examples of fasteners include hook-and-loop fasteners, snaps, and zippers. A portion of the fastener (e.g., a hook pad) can be on the flap 1227, and a portion of the fastener can be on an adjacent portion of the basket shell 1220. When the flaps or panels are not fastened, the basket 1200 can collapse. To fasten the flaps 1227, stiffeners in the shell can be forced apart and into a deployed position. Forcing the stiffeners apart can erect the reinforced sidewalls 1222 of the basket 1200, allowing the basket to stand on its base, for example, supporting the basket frame 1210.

[0106] FIG. 13A shows further details of track 1250, which may be included with basket 1200 of FIG. 12B and used to secure a seat mount adapter to basket frame 1210.

[0110] While various embodiments of the present invention have been described and illustrated herein, those skilled in the art will readily envision various other means and / or structures for performing the functions and / or obtaining one or more of the results and / or advantages described herein, and each such variation and / or modification is deemed to be within the scope of the embodiments of the present invention described herein. More generally, those skilled in the art will readily understand that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary, and that the actual parameters, dimensions, materials, and / or configurations will depend on the particular use or application for which the teachings of the present invention are used. Those skilled in the art will readily recognize or be able to ascertain, using no more than routine experimentation, many equivalents to the specific embodiments of the present invention described herein. Accordingly, it should be understood that the foregoing embodiments are presented by way of example only, and that, within the scope of the appended claims and their equivalents, embodiments of the present invention may be practiced otherwise than as specifically described and claimed. The inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and / or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and / or methods is included within the inventive scope of the present disclosure, provided that such features, systems, articles, materials, kits, and / or methods are not mutually inconsistent.

[0111] Also, various inventive concepts may be embodied as one or more methods, examples of which have been provided. The acts performed as part of a method may be ordered in any suitable manner. Accordingly, various embodiments may be constructed in which acts are performed in an order different from that shown, which may include performing some acts simultaneously although shown as sequential acts in the illustrative embodiments.

[0112] All definitions, as defined and used herein, should be understood to govern dictionary definitions, definitions in documents incorporated by reference, and / or ordinary meanings of the defined terms.

[0113] The indefinite articles "a" and "an," as used in the specification and claims, unless clearly indicated to the contrary, should be understood to mean "at least one."

[0114] The phrase "and / or" as used in this specification and the claims should be understood to mean "either or both" of the components so conjoined (i.e., components that are conjunctively present in some cases and disjunctively present in other cases). Multiple components listed with "and / or" should be construed in the same manner (i.e., "one or more" of the components so conjoined). Other components, whether related or unrelated to those specifically identified, can optionally be present other than the components specifically identified by the "and / or" clause. Thus, as a non-limiting example, a reference to "A and / or B," when used in conjunction with open-ended language such as "comprising," can, in one embodiment, refer only to A (optionally including components other than B); in another embodiment, refer only to B (optionally including components other than A); in yet another embodiment, refer to both A and B (optionally including other components), etc.

[0115] As used herein and in the claims, "or" should be understood to have the same meaning as "and / or" as defined above. For example, when separating items in a list, "or" or "and / or" should be interpreted as inclusive (i.e., including at least one (including more than one) of a plurality of components or list of components, and, optionally, including additional unlisted items). Only terms clearly indicating the contrary (e.g., "only one of" or "exactly one of," or, when used in the claims, "consisting of") will refer to the inclusion of exactly one component of a plurality of components or list of components. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., "one or the other, but not both") when preceded by terms of exclusivity (e.g., "either," "one of," "only one of," or "exactly one of") "Consisting essentially of," when used in the claims, shall have its ordinary meaning as used in the field of patent law.

[0116] As used herein and in the claims, the phrase "at least one" in reference to a list of one or more components should be understood to mean at least one component selected from any one or more of the components in the list of components, but not necessarily including at least one of each and every component specifically listed in the list of components, and not excluding any combination of components in the list of components. This definition also allows for components to be optionally present other than those specifically identified in the list of components to which the phrase "at least one" refers, whether related or unrelated to those specifically identified components. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B" or, equivalently, "at least one of A and / or B") can refer in one embodiment to at least one A (optionally including more than one) and no B (and optionally including components other than B); in another embodiment to at least one B (optionally including more than one) and no A (and optionally including components other than A); in yet another embodiment to at least one A (optionally including more than one) and at least one B (optionally including more than one) (and optionally including other components), etc.

[0117] In the claims and in the above specification, all transitional phrases (e.g., "comprising," "including," "carrying," "having," "containing," "involving," "holding," and "composed of") are to be understood to be open-ended (i.e., meaning "including, but not limited to").
