A hand truck with main wheels and a toe plate also includes a handle assembly that is mounted to the frame of the hand truck so that the handle assembly is able to rotate and slide relative to the truck frame. The hand truck may be arranged in a first upright dolly position in which the handle assembly is generally aligned with the truck frame and a second cart position in which the truck frame is generally horizontal and the handle assembly is extended and rotated so that it is upright and normal relative to the truck frame. A latch assembly mounted to the truck frame is able to releasably receive and secure the handle assembly in the first upright dolly position.

A device has a cuboidal basket portion defining a cavity. A front pair of legs is attached to the basket portion such that the front legs are pivotable about a first axis, and each front leg has a wheel. A rear pair of legs is attached to the basket portion such that the rear legs are pivotable about a second axis, and each rear leg has a wheel. A handle is attached to the basket portion and is pivotable around a third axis. The device has a basket configuration in which the handle is located across and above the basket portion and the legs are collapsed with the wheels located adjacent to a base of the basket portion. The device has a trolley configuration in which the handle is located rearward of the basket portion and the legs are extended for supporting the basket portion.

A foldable cart includes a handle portion, a foldable frame movably connected to the handle, and one or more wheels for rolling on a surface. In an unfolded (in-use or open) condition, the foldable frame constructs a holding-space defining a receiving cavity therein for carrying items, and the action of unfolding the frame automatically deploys wheels to enable immediate use of the cart by the end-user or customer. In a folded (storage or closed) condition, the carts' frame folds to occupy a smaller space in one or more spatial dimensions, and the automatically deployed wheels turn to occupy smaller total space in one or more spatial dimensions. In the folded condition, the cart is easy to store in a small space (e.g. in a small closet, under a bed, etc.) or transport (e.g. in the trunk of an automobile, vehicle, airplane, train, ship with a courier, etc.).

The assembled-type traveling carriage includes: the telescopic cylindrical body being an extendable telescopic cylindrical body rotatably provided with a first screw at each end thereof, and incorporating an actuator configured to extend and withdraw a nest; a joint block provided with a second screw; a traveler rotatably provided with the first screw and attached a driving device thereto; and a coupling rod rotatably provided with the first screw on each end thereof. A first planar frame body is assembled by screwing joint blocks to four of the telescopic cylindrical bodies, screwing the travelers to the joint blocks such that the travelers are positioned on extension lines of the telescopic cylindrical bodies, and coupling one ends of the four telescopic cylindrical bodies to one another by the coupling rods through the joint blocks.

Disclosed is a dual-purpose folding trolley comprising a handle with lower end of handle's both sides into lower connecting sleeve that is mounted at bend of handle's lower end. Locking tube is into lower connecting sleeve's inner side with switches sleeved on tube. Locking tube's interior has locking rod first spring sleeved on rod. Lower connecting sleeve's outer side is connected to fixing connecting block, and block rotatably connected to movable caster via short connecting tube. First torsion spring sleeved on short connecting tube. Upper horizontal tube is at handle's lower end and locking tube's lower side. Upper horizontal tube sleeve sleeved on upper horizontal tube's middle portion. Middle portion of upper horizontal tube sleeve's upper end connected with upper connecting tube. Lower bending tube is into fixing connecting block's lower end. Dual-purpose folding trolley converts into two or four-wheel using states is convenient, wide application range, foldable, and compact.

A folding handcart includes: a main body provided with a supporter configured to extend vertically from a lower portion thereof; and a loading plate provided with at least one loading plate wheel unit, connected to the supporter of the main body through a hinge unit, folded while being rotated toward the main body by the hinge unit, and stowing an article or a folding box, wherein, when the loading plate is folded while being rotated toward the main body, a predetermined stowing space is provided between the main body and the loading plate in accordance with an area of the supporter such that the folding box is folded and stowed therein.

A foldable or collapsible cart can be oriented in several different configurations to accommodate different loads and transport requirements. In one configuration, the cart may be folded for direct load the back of a vehicle. In another configuration, the cart can operate in lowboy or dolly mode. In another configuration the cart may be used as a hand truck.

The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.

The present invention discloses a folding stair-climbing trolley comprising a bracket, wherein two insertion posts at a lower end of the bracket are sequentially inserted into a sliding sleeve, a sliding inner sleeve, a supporting sleeve, a toothed tube sleeve, a torsion spring and a foot stand, and ends of the two insertion posts at the lower end of the bracket are rotatably connected to both ends of a blade; a lower end of a supporting seat is connected to a lower portion of a rotating block and is located at an upper side of a connection point between the foot stand and the rotating block; an upper end of the rotating block is connected to a tripod, and three ends of the tripod are rotatably connected to rollers. The folding stair-climbing trolley may realize the function of moving on the stairs by providing three rollers. And the supporting sleeve and foot stand provided can be rotated, which may facilitate the tripods on both sides to be turned over and folded inward to realize the function of storing the rollers, saving the space for storing the trolley. By providing the oblique openings at the upper end of the foot stand and the lower end of the toothed tube sleeve, and providing the torsion spring inside the foot stand, the rotating thrust of the torsion spring facilitates the unfolding of the tripods.

A load transport cart for transporting loads includes a carrier frame, which has a first and a second carrier frame section, the first carrier frame section extending in a first extension plane, and the second carrier frame section extending in a second extension plane, at least two wheels being situated on the back side of the first carrier frame section for moving the load transport cart, and at least one first foldable tray, which is situated on the front side of the first carrier frame section, the load transport cart also including at least one second foldable tray, which is situated on the front side of the second carrier frame section, the second carrier frame section being pivotable, relative to the first carrier frame section, between a folded position and an unfolded position around an essentially horizontal carrier frame pivot axis situated between the first and second carrier frame sections.
