Abstract: A collapsible cart includes a pivotable platform, a pivotable handle, and collapsible and adjustable tube assemblies for placing the cart in an extended or retracted position. The cart opens to a two-wheel hand truck or a four-wheel cart. It also closes to a compact configuration, making it highly portable and easy to store.

Abstract: A handle assembly for carts and wheeled luggage includes a pair of tube assemblies disposed in substantially parallel relation and connected by a handle member. The tube assemblies carry locks that cooperate with the tubes to releasably lock the tube assemblies in an extended or a retracted position.

Abstract: A handle assembly for carts and wheeled luggage includes a pair of tube assemblies disposed in substantially parallel relation and connected by a handle member. The handle assembly includes an actuating and latching apparatus for releasably locking the tube assemblies in an extended or retracted position.

Abstract: A portable luggage carrier includes a handle member and a base member pivotally connected to the handle member for supporting luggage. An axle pivotally mounted to the handle member supports a pair of wheels which lie on opposite ends of the axle, rotatably mounted to the axle. Latching devices releasably secure the axle in predetermined positions.

Abstract: A two-wheeled cart for transporting articles such as luggage and the like is equipped with an auxiliary wheel which is movable between a storage position and a use position in which the cart is self-supporting. The cart includes a base portion and a handle portion, and the base portion includes a pair of parallel tubes and an axle which extends between the tubes and supports a pair of wheels. The auxiliary wheel is mounted on an auxiliary wheel frame which is movably mounted on the base portion for movement between a storage position in which the wheel frame extends generally parallel to the parallel tubes and a use position in which the auxiliary wheel supports the handle portion at an acute angle with respect to the supporting surface.

Abstract: A luggage carrier is provided with a pivoting handle which pivots between a use position and a storage position. The handle is pivotally attached to a pair of spaced-apart rods which extend upwardly from the base of the luggage carrier, and locking tubes which are slidably mounted on the handle are slidable over the upper ends of the rods to lock the handle in its use position.

Abstract: A garment bag attachment is removably mounted on a portable luggage carrier. The luggage carrier includes a base and a handle assembly extending upwardly from the base. The handle assembly includes a pair of spaced-apart handle members and a cross brace connecting the handle members at their upper ends. The garment bag attachment includes a wire frame which is bent into an inverted U shape with a pair of parallel side portions, a cross portion, and a loop in the cross portion. The end portions of the side portions are bent transversely inwardly. A pair of mounting brackets are secured to the handle assembly, and each mounting bracket is provided with a groove which is sized to receive one of the side portions of the wire frame and an opening which extends transversely to the groove. The wire frame is mounted on the luggage carrier by flexing the side portions away from each other until the end portions of the frame can be inserted into the openings in the mounting brackets.

Abstract: A portable luggage carrier is provided with a luggage-supporting base which is movable between a luggage-supporting position and a storage position. The luggage carrier includes a frame having a pair of spaced-apart frame members, a bracket mounted on each frame member, and an axle extending between the brackets. A pair of wheels are mounted on the axle. The base is provided by a generally U-shaped rod, the ends of which are looped around the axle so that the base is pivotally connected to the axle. A detent projection is mounted on each of the brackets for engagement with one of the end portions of the U-shaped rod for releasably locking the base in the luggage-supporting position.
