A cart includes a platform assembly, a handle assembly, first wheel assembly and a second wheel assembly. In use, the cart may folded from a deployed position in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may be further integrated into a chair, chaise lounge, garden cart, bicycle utility cart or a bicycle passenger cart.

A transport device in the form of a cart or cargo hauler is foldable to permit the device to be used in transport applications with narrow or constrained parameters. The device may be loaded or unloaded when folded or unfolded, providing a flexible implementation that improves ease of transport. The device may include one or more wheels or skis depending on a desired application. Handles may be provided that telescope and/or fold to provide a compact folded configuration. The transport device may be folded compactly so as to be carried with a backpack or shoulder harness. The handles may be attached to waist belt or shoulder harness to permit hands-free transport. The device is suitable for use over rough back country terrain or sand.

A lightweight collapsible stroller is provided. The stroller includes: a frame including a first portion movable relative to a second portion; a drive mechanism coupled to the frame, which moves the first portion relative to the second portion, thereby transitioning the frame between an open position and a closed position; and a latch mounted to the frame. The latch is positioned to engage at least a portion of the first portion or the second portion when the frame is in its open position to restrict the first portion from moving relative to the second portion. Upon actuation, the drive mechanism causes the latch to release, such that the first portion of the frame moves relative to the second portion of the frame, thereby allowing the frame to transition to the closed position.

A collapsible trolley includes a handle unit, an adjustment unit, a bearer, a strut and a strut-positioning unit. The handle unit includes two telescopic elements. The adjustment unit is operable to adjust the length of the telescopic elements. The bearer is connected to the handle unit. The strut is pivotally connected to the handle unit. The strut-positioning unit is operable to keep the strut in position relative to the handle unit. A user can disable the strut-positioning unit to release the strut from the handle unit without having to use any hand or bend.

In accordance with some aspects of the present disclosure, there is provided a foldable stroller frame comprising a first side frame member, a second side frame member, a middle frame member, and a sliding mechanism configured to slide along the middle frame member. First and second cross frame members may connect the sliding mechanism to the first and second side frame members. In some examples, the first and second cross frame members may comprise a curved portion proximate the connection with the side frame members. The sliding member may comprise an upper portion and a lower portion. In some examples, spring-biased tongues disposed in the lower portion may bias the upper portion. In some examples third and fourth cross frame members may connect the first side frame member and the second side frame member to a foot pedal that may be disposed on the middle frame member.

A laterally collapsible, user-pushed, four-wheeled rollator, stroller or the like has swiveling front wheels for steering, each mounted in a fork with a vertical post, with a toothed pulley fixed thereto, rotatable in a bearing housing fixed at the front end of right and left side frames. The two swiveling front wheels can swivel to any steering angle but always in unison with each other by virtue of a flexible toothed synchronous belt extending between the toothed pulleys. The interior of each bearing housing closely surrounds each toothed pulley and the belt, preventing any disengagement of the belt from either toothed pulley even when the belt becomes slack when the left and right side frames are folded towards each other. A synchronous chain with sprockets can also be used. Tether means pull the belt/chain rearwardly to a protected position during folding.

A wagon is adjustable between a collapsed configuration, an intermediate configuration, and an expanded configuration. The frame has a vertical pole assembly arranged at each of the four corners of the frame. Each of the vertical pole assemblies comprises an extension member telescopically arranged with a fixed member and a slider operatively slidingly connected with the fixed member. When the frame is altered from the expanded configuration to the intermediate configuration, the slider of each vertical pole assembly moves away from the distal end of the fixed member toward the proximal end of the fixed member and the extension member moves from the raised position to the lowered position. When the frame is altered from the intermediate configuration to the collapsed configuration, the extension member moves from the lowered position to the raised position with the slider at or adjacent to the proximal end of the fixed member.

A camping wagon achieves high portability and large capacity. Meanwhile, the camping wagon features lower sales costs and more cost-effective packaging in the e-commerce field. In the camping wagon, each of four corners of a folding bottom frame is provided with one support rod; one first folding side frame is provided between each two adjacent support rods in a width direction of the folding bottom frame, and one second folding side frame is provided between each two adjacent support rods in a length direction of the folding bottom frame; upper side ends of two second X-shaped movable frames of the second folding side frame are respectively hinged to corresponding support rods through linkage rods; and two upper side ends of one third X-shaped movable frame of the first folding side frame are respectively hinged to corresponding support rods through linkage rods.

A cart includes a fixed platform having a first edge and a first top surface for carrying cargos, a foldable platform having a second top surface for carrying cargos and a second edge pivotally attached to the first edge, the foldable platform pivoting between a horizontal position and an upright position, the first and second top surface being in the same plane when the foldable platform being at the horizontal position, a support structure extended from the fixed platform to beneath the foldable platform, and a support rod pivotally attached to a bottom surface of the foldable platform and pivoting between a first and second angle to the foldable platform, the second angle being different from the first angle, when at the second angle, the support rod, the support structure, the fixed platform and the foldable platform forming a triangle holding the foldable platform at the upright position.
