ABSTRACT:
An improved cart capable of being readily collapsed for storage and having front wheel means and a pair of spaced stair-climbing assemblies for moving the cart over a surface and for allowing the cart to move up or down a flight of stairs. The cart has a normally inclined main frame to which one or more open top wire baskets can be coupled by hooks thereon. Rear support structure for the main frame includes a pair of normally inclined, rearwardly extending rods pivotally mounted at their upper ends to the main frame and having articulated links to keep the main frame and the rods normally apart but which allow the rods to collapse and to move into positions near and extending along the main frame. The stair-climbing assemblies are pivotally mounted on the lower ends of the rods and respective links which normally hold the upper ends of the assemblies spaced from the rods yet permit the assemblies to collapse to positions extending along and adjacent to the rods. In its collapsed state, the cart is compact in size and easily carried or stored with or without the baskets mounted on the hooks of the main frame.
