First and second rear wheels are rotatably connected to the wagon frame adjacent the second end assembly, and first and second front wheels are rotatably and pivotally connected to the wagon frame adjacent the first end assembly. The handle is pivotally connected to the first end assembly, and the push bar is pivotally connected to the second end assembly. The push bar is lockably positionable in a plurality of use positions and a storage position with a ratchet mechanism.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

Embodiments disclosed herein are generally related to children's stroller systems and more particularly to systems, methods, and apparatus for providing a compact automatic folding stroller. In at least one embodiment, a compact automatic folding stroller can be provided. The stroller can include a stroller frame comprising a handle member, a front leg member, and a rear leg member; and a hub mechanism, wherein the handle member, front leg member, and rear leg member are coupled to one another via the hub mechanism, the hub mechanism includes: a handle arm operable to connect to a lower portion of the handle member; a front leg arm operable to connect to the front leg member; and a rear leg arm operable to connect to the rear leg member; and a linkage operable to coordinate movements of the handle arm, front leg arm, and rear leg arm; wherein when an upper portion of the handle member is manipulated towards the lower portion of the handle member, the hub mechanism releases the linkage, causing the linkage to: rotate the front leg arm to fold the front leg member towards the rear leg member; rotate the handle arm to fold the lower portion of the handle member towards the rear leg member; wherein the front leg member, upper portion of the handle member, and lower portion of the handle member can be maintained in a folded configuration with respect to the rear leg member.

The present application discloses a stroller frame switchable between an unfolded position and a folded position. The stroller frame includes an unfolding and folding mechanism, a front foot support, a rear foot support, a first connecting bar, and a second connecting bar. The unfolding and folding mechanism includes a supporting body and a movable body movable relative to the supporting body. The front foot support is pivotally connected to the supporting body. The rear foot support is pivotally connected to the supporting body, the rear foot support is pivotable relative to the front foot support. The first connecting bar is pivotally connected to the front foot support and the movable body, respectively. The second connecting bar is pivotally connected to the rear foot support and the movable body, respectively, and the second connecting bar is pivotable relative to the first connecting bar.

A rod locking mechanism includes a central hub, a first rod component and a locking component. The first rod component is pivotally connected to the central hub. The first rod component includes an abutting portion. The abutting portion is movable between a first position and a second position when the first rod component pivots relative to the central hub. The locking component is movably disposed on the central hub. The abutting portion is located at a first side of the locking component when the abutting portion is located at the first position. The abutting portion drives the locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abuts against a second side of the locking component opposite to the first side of the locking component when the abutting portion is located at the second position.

A foldable cart comprising an upper frame, a lower frame, and a plurality of legs attached to and supporting the upper frame and the lower frame is disclosed. Each leg is configured to be folded into a folded configuration from an erect configuration. Each leg comprises a lock configured to hold the leg in the erect configuration. The lock comprises a lock bar movable between a locking position and an unlocking position, an internal support brace, wherein the lock bar extends through the internal support brace, and a spring configured to bias the lock bar into the locking position to hold the leg in the erect configuration. The lock bar is spring-loaded against the internal support brace, wherein the entire length of the spring surrounds the lock bar, and wherein the spring is confined entirely within the internal support brace.

The present disclosure provides a canopy adjustment mechanism comprising a canopy, a locking mechanism, and a lock receiving mechanism provided on the canopy. The locking mechanism locks at different positions of the lock receiving mechanism to achieve height adjustment of the canopy. The height of the canopy can be changed to suit children of different heights, and accordingly, the installation position of the canopy can be flexibly changed to meet the needs of users. Moreover, the canopy adjustment mechanism is easy to operate in terms of height adjustment and simple in structure. The present disclosure further provides a baby carrier comprising the aforesaid canopy adjustment mechanism.

A carrier adjusting mechanism is applied to a stroller including a stroller frame and a carrier and includes a base, a locking structure, a locking device, and a release actuator. The base is connected to the stroller frame. The locking structure is connected to the carrier and pivoted to the base. The locking device is disposed between the base and the locking structure. The locking device includes a first engaging structure, a second engaging structure, and a locking member. The locking member is engaged with the first engaging structure at a first position or the second engaging structure at the second position. The release actuator is disposed on the stroller and connected to the locking device for disengaging the locking member from the first engaging structure or the second engaging structure, to allow the locking structure to move between the first position and the second position together with the carrier.
