The present folding cart is comprised of a rectangular bag and flexible support panel positioned within a rectangular frame, and wheels connected to the frame by legs. The frame is comprised of pairs of scissoring members on the ends and sides for being quickly collapsible in two dimensions. The ends of the scissoring members in each pair are offset toward each other at the corners of the frame to avoid binding during folding. An arched section is provided in each leg at one end of the frame that curve around the wheel at the other end of the frame when folded. A flexible bag is attached to the top corners of the frame, but not to the bottom corners to enable the frame to be collapsed. The flexible support panel is attached to the bottom corners of the frame to prevent the bag from sagging under a heavy load.

1. A folding cart, comprising:a collapsible frame which is extended in a vertical direction and compacted in two horizontal directions when collapsed, said frame being defined by front and rear scissoring assemblies, and at least a pair of side scissoring assemblies extending transversely between said front and rear scissoring assemblies, each said front, rear, and side scissoring assembly including at least one pair of crossed scissoring members pivotally joined at an intermediate point, at least one scissoring member of each said front and rear scissoring assembly being joined to each of said side scissoring assemblies in pivotally displaceable manner about a pair of axes, said front, rear, and side scissoring assemblies being collapsible respectively about said intermediate points thereof; at least a first of said scissoring members of each said side scissoring assembly terminating at a first leg portion having a front wheel rotatably coupled thereto, and at least a second of said side scissoring members of each said side scissoring assembly terminating at a second leg portion having a rear wheel rotatably coupled thereto, at least one of said first and second leg portions including an arched section for receiving in nested manner said wheel coupled to the other of said first and second leg portions when said frame is collapsed; a bag positioned within said frame and attached to said front, rear, and side scissoring assemblies of said frame to avoid impeding collapse of said frame, a bottom of said bag remaining detached from said frame to facilitate folding; and a flexible horizontal support panel secured across a lower end of said frame for supporting said bag when subjected to a load, and for providing lateral rigidity to said frame.
