A child stroller apparatus includes a first side segment connected fixedly with a first shell portion and a grip portion that are disposed adjacent to each other, a second side segment fixedly connected with a second shell portion that is pivotally connected with the first shell portion, a latch assembled in a cavity delimited at least partially by the first and second shell portions, the latch being movable between a locking position that prevents relative rotation between the first and second side segments and thereby locks the child stroller apparatus in an unfolded state for use, and an unlocking position for folding and unfolding of the child stroller apparatus, and a release actuator assembled adjacent to the grip portion and operatively coupled to the latch, the release actuator being operable to cause the latch to move from the locking position to the unlocking position.

A child stroller apparatus includes a stroller frame, and an adapter assembled with the stroller frame and having a first coupling portion and a second coupling portion, each of the first and second coupling portions being configurable as a mount for installation of a detachable part. The adapter is movable relative to the stroller frame to displace the first and second coupling portions, a first position of the adapter configuring the first coupling portion as the mount while maintaining an angle between the first coupling portion and the second coupling portion, and a second position of the adapter configuring the second coupling portion as the mount while maintaining the angle between the first coupling portion and the second coupling portion.

A translational collapsible wagon includes a frame assembly, a tow bar assembly and wheels. The frame assembly includes a bottom frame, a front frame, a rear frame and collapsible side frames arranged on the left side and the right side of the bottom frame. Each side frame includes coplanar X-shaped cross tube assemblies. Each coplanar X-shaped cross tube assembly includes a first oblique tube, two second oblique tubes and a hollow seat. A strip opening is formed in the middle of the hollow seat in the front-back direction. Tube connectors are oppositely arranged at the front end and the rear end of the hollow seat in the vertical direction respectively. The first oblique tube penetrates through the strip opening and is hinged to the middle of the strip opening at the center through a hinge shaft. The two second oblique tubes are mounted in the tube connectors at the front end and the rear end of the hollow seat respectively and arranged in parallel and intersect with the first oblique in an X shape. The first oblique tube, the two second oblique tubes and the hollow seat are all located on the same plane.

A stroller includes a chassis and a child support. The chassis is configured to roll along the ground in response to being pushed by a caregiver. The child support is coupled selectively to the chassis and is configured to support a child resting therein.

A collapsible stroller includes a stroller frame, a folding lock mechanism, a lateral lock mechanism, and a trigger mechanism. The stroller frame includes a right upper side frame member pivotally connected with a right lower side frame member and a left upper side frame member pivotally connected with a left lower side frame member. The folding lock mechanism is capable of a locked state and an unlocked state. The lateral lock mechanism is capable of a locked operating state and an unlocked operating state. The trigger mechanism is on the stroller frame, and actuation of the trigger mechanism moves the folding lock mechanism from the locked state to the unlocked state and moves the lateral lock mechanism from the locked operating state to the unlocked operating state.

A hand trolley includes a trolley main body and a handle assembly. The handle assembly includes a handle, a fastener, and an elastic member. The handle is displaced relative to the trolley main body between a folded position and an unfolded position. The fastener is pivotally connected to the handle. The elastic member is connected with the handle and the fastener to provide an elastic force for the fastener to be located at a predetermined fastening position. When the handle is displaced relative to the trolley main body toward the unfolded position, the fastener is pivoted to engage with an engaging portion of the trolley main body.

A foldable utility cart is lightweight and easily conveyed up and down a wind turbine for transporting parts and tools used for repair and maintenance of a wind turbine. A set of wheels allow the cart to be easily rolled along the nacelle and an attachment bar secures the cart to a guidance rail.

Embodiments of the present disclosure may include a collapsible cart configured to transition from a closed condition where it may be folded up to an open condition where it may be expanded for use, the collapsible cart including a rigid frame forming a compartment, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall may be configured to fold inwardly in the closed condition. In some embodiments, the right sidewall including a first right panel rotatably coupled to a second right panel. In some embodiments, a retractable handle mechanism is disposed at, within or adjacent the back wall. The retractable handle mechanism includes a hand grip attached to a telescoping assembly. The telescoping assembly is pivotably coupled at a proximal end to the bottom of the rear wall.

An infant stroller apparatus includes a front leg frame having a first side segment, a handle frame having a second side segment pivotally coupled with the first side segment via a first pivot connection, a rear leg frame having a third and a fourth side segment pivotally coupled with each other via a second pivot connection, the third side segment being further pivotally coupled with the first side segment via a third pivot connection, and the fourth side segment being further pivotally coupled with the second side segment via a fourth pivot connection, a seat portion pivotally coupled with the first side segment via a fifth pivot connection, and a support frame portion respectively coupled with the seat portion and the fourth side segment.
