In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a base frame having a group of wheels configured to allow the mother cart to be moved. The base frame, in turn, includes a loading bay for receiving the daughter cart, and a support surface for supporting the daughter cart. Finally, the base frame includes a primary restraint mechanism for engaging and securing the daughter cart in the loading bay.

A tugger cart includes a tugger frame having a first side member, a second side member, and a locking member disposed in between the first side member and the second side member. A first roller assembly is coupled to an inner surface of the first side member and a second roller assembly coupled to an inner surface of the second side member. Each of the first roller assembly and the second roller assembly include a roller assembly frame and a plurality of wheels rotatably coupled to the roller assembly frame. The roller assembly frame supports the plurality of wheels at a slant that declines from a rear of the tugger frame to a front of the tugger frame. An actuator is configured to raise and lower the first roller assembly and the second roller assembly relative to the first side member and the second side member respectively.

A hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform having a swing out support frame having an upper end hingedly attached to the rear side of the center frame which is movable between an extended position and a stored position. A corresponding sofa dolly and a platform enclosure is also disclosed.

A cart apparatus includes a child cart that includes a base frame structure including a pair of side beams and a lateral beam that extends between the pair of side beams. A parent cart includes a base frame structure including a pair of side beams and a lateral beam that extends between the pair of side beams. The base frame structure of the parent cart defines a nesting area that is sized and arranged to receive the base frame structure of the child cart. A cart interlock mechanism includes an engagement member that is rotatably mounted to the base frame structure and a foot pedal that is linked to the engagement member. The foot pedal rotates the engagement member from a locked position that engages the base frame of the child cart to an unlocked position that releases the base frame of the child cart.

An automatic guided vehicle according to one aspect of the present invention moves a trolley including a trolley body, wheels attached to the trolley body, and a section to be connected which is provided on the lower surface of the trolley body. The automatic guided vehicle is provided with: a vehicle body; drive wheels attached to the vehicle body; and a connection mechanism which is connected to the trolley, wherein the connection mechanism includes a connecting section disposed on an upper side of the upper surface of the vehicle body so as to be movable horizontally in a first direction, and includes a drive apparatus which moves the connecting section in the first direction and connects the connecting section to the section to be connected.

A cart for connecting or attaching to a wheelchair is provided to assist a wheelchair user to more easily collect and move items, such as groceries. In certain embodiments the cart is further defined as a shopping cart.

A transportation dolly can have a frame, two axles pivotally coupled with the frame, each axle having two distal ends and a wheel assembly coupled at each distal end and a synchronous steering system. The synchronous steering system can include an intermediate link pivotally coupled with the frame, the intermediate link having a two distal ends, and a first push-pull rod coupling one of the two axles with the intermediate link, and a second push-pull rod coupling the other of the two axles with the intermediate link. The first push-pull rod is coupled to one distal end of the intermediate link and the second push-pull rod is coupled to the opposing distal end of the intermediate link. The first push-pull rod, the second push-pull rod, and the intermediate link provide counter phase synchronous pivoting of the two axles relative to the transportation dolly.

A tugger cart includes a tugger frame having a first side member, a second side member, and a locking member disposed in between the first side member and the second side member. A first roller assembly is coupled to an inner surface of the first side member and a second roller assembly coupled to an inner surface of the second side member. Each of the first roller assembly and the second roller assembly include a roller assembly frame and a plurality of wheels rotatably coupled to the roller assembly frame. The roller assembly frame supports the plurality of wheels at a slant that declines from a rear of the tugger frame to a front of the tugger frame. An actuator is configured to raise and lower the first roller assembly and the second roller assembly relative to the first side member and the second side member respectively.

A hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform. A platform enclosure is also disclosed.

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.
