A foldable golf trolley comprising a chassis; at least one electrically powered rear drive wheel; a wheel support arm mounted to the front of the chassis supporting a front wheel; a stabilizer arm mounted to the rear of the chassis supporting a stabilizer wheel; a main support mounted to the chassis and a handle mounted to the main support; wherein the main support, the wheel support arm and the stabilizer arm are rotatably mounted to the chassis and movable between an operative configuration and a folded configuration; and gears connecting the stabilizer arm and main support, wherein rotation of the main support between the operative configuration and the folded configuration cause rotation of the stabilizer arm between the operative configuration and the folded configuration.

Disclosed is a four-wheeled folding handcart, including: a main body; and a loading plate provided with at least one loading plate wheel unit at a lower portion thereof, connected to the main body via a hinge unit such that the loading plate is folded by the hinge unit while being rotated toward the main body, and loading an article thereon. The loading plate wheel unit is connected to a wheel rod rotated by the rotation of the hinge unit in a direction perpendicular to a rotational direction of the hinge unit. The loading plate wheel unit is configured such that, when the loading plate is rotated and folded, the loading plate wheel unit is rotated and folded as the wheel rod rotates, and when the loading plate is rotated and unfolded, the loading plate wheel unit is rotated and unfolded as the wheel rod rotates reversely.

A folding cart includes a frame body. The frame body includes a chassis, lower hinge seats, a front folding mechanism, a rear folding mechanism, and side-folding mechanisms. The chassis comprises two X-shaped crossed hinge structures, inner ends of left and right sides of the two X-shaped crossed hinge structures are hinged together with a first connector. A middle part of the side-folding mechanism has a second connector. Outer ends of the X-shaped crossed hinge structures are universally hinged with the corresponding lower hinge seats. Each of the X-shaped crossed hinge structure comprises a first bottom rod, a bottom rod connecting seat hinged with a middle part of the first bottom rod, and two second bottom rods respectively hinged with both ends of the bottom rod connecting seat.

A folding dolly system, a base unit of a folding dolly system, and methods of forming and using a folding dolly system are presented. A folding dolly system comprises a plurality of interconnectable base units connected to form a substantially planar holding surface, each base unit comprising a first edge with a number of knuckles configured to form a joint, a second edge with a number of knuckles configured to form a joint, and a surface forming a portion of the holding surface.

The present invention discloses a folding cart, which comprises a left frame, a right frame, plurality of platforms, a left connecting rod, a right connecting rod, a guide rod, a sliding sleeve, a pressing member, a moving block and an elastic member. The sliding sleeve, disposed on the guide rod and slidable up and down relative to the guide rod, has a limiting hole opposite to the second opening of the guide rod. The pressing member has a first slope. The moving block has a second slope and a limiting protrusion. By the slope sliding between the pressing member and the moving block and the sliding of the sliding sleeve along the guide rod, the sliding is smooth, with low friction. Therefore, not too much force is required and the operation is thus easier.

A collapsible cart may include a first frame member, a second frame member, a front spacing member, a rear spacing member, and a base member. The front and rear spacing members are configured to separate the first frame member and the second frame member for a predetermined distance to create a receiving space for the cart when it is in a fully open status. The base member may have a plurality of base connecting bars and a center unit that has four opening to pivotally engage with the base connecting bars, and the center unit and the four base connecting bars are positioned on the same plane surface when the cart is in a fully open status. The user can start collapsing the cart by simply pushing down the center unit to disengage the center units with the base connecting bars.

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 folding cart includes a frame body and a handle mechanism. The frame body comprises a chassis, four lower hinged seats at four corners of the chassis, a front folding mechanism in front of the chassis, a rear folding mechanism behind the chassis and two side folding mechanisms on the side of the chassis. A bottom portion of the lower hinged seats is provided with wheels. The chassis is an X-shaped cross-hinged structure and has four end portions respectively hinged to the lower hinged seats. The side folding mechanism has at least one X-shaped cross-hinged rod assembly with upper ends hinged to the upper hinged seats and lower ends hinged to the lower hinged seats. The front folding mechanism and the rear folding mechanism respectively have at least one X-shaped cross-hinged rod assembly having two hinged cross rods.

A vehicle system includes a chassis, a plurality of wheels coupled to the chassis and supporting the chassis for rolling on a surface, and a riding platform coupled to the chassis. The riding platform is for supporting a user behind the chassis when the riding platform is in a downward pivoted state. A linkage connects the riding platform to the chassis for selective pivotal motion relative to the chassis between an upward pivoted state in which the riding platform is pivoted into a position to allow a user to walk behind the chassis and a downward pivoted state in which the user may ride or step on the platform.

A foldable rollable golf bag trolley comprising a push handle assembly, a front leg assembly a left rear leg assembly, a right rear leg assembly, a folding mechanism having two universal joint sub-assemblies, a series of hubs and ramp discs, wherein said components of the folding mechanism are aligned about a central axis of a main pivot shaft in a first position. The folding mechanism further comprising a plurality of locking gears and springs wherein the two universal joint sub-assemblies and a left and right ramp disc cause a left rear hub and a right rear hub to move in two dimensions when the folding mechanism is engaged in a second position.
