ABSTRACT:
The trolley has a collapsible structure composed of rigid or semi-rigid, typically cardboard panels. The panels can be folded relative to one another between a collapsed state in which the majority of them lie in compact, coplanar relationship and an erected state in which they define an open-topped box. A wheeled axle is connected to the structure to permit the box to wheeled over the ground. Handles are provided for carrying the structure when collapsed and for steering the trolley when erected. Also, tabs are provided that lock in suitable slots to maintain the collapsed and erected condition of the panels.
