ABSTRACT:
Two-wheeled carts can be constructed so that their bodies can be manipulated between a normal, expanded configuration in which such carts can be used and a folded, relatively compact configuration in which such carts may be easily and conveniently stored. Such foldable carts include side walls, at least one of which is constructed so as to include two panels and a hinge connecting such panels in edge-to-edge relationship. A connector pivotally connects the side walls so that they can be manipulated so as to be moved generally toward one another as the structure is manipulated from the unfolded to the folded configuration. The extremities of these side walls are connected by end walls each of which consist of two wall sections connected in edge-to-edge relationship by center edge hinges. The wall sections have side edges which are connected to the sides by side edge hinges.
