A center collapsible transport cart having at least two floor panels pivotally connected along a longitudinal pivot axis. Side panels and end members may be attached to the outer edges of the floor panel to form a desired cargo bed enclosure. When the cart is in its “operative”configuration the floor panels are horizontally disposed in approximate edge-to-edge juxtaposition. When converted to its “stowed”configuration the floor panels are generally vertically disposed in surface-to-surface juxtaposition, thereby forming a relatively flat collapsed structure. A tow bar handle is also pivotally disposable between the vertically juxtapositioned floor panels when the cart is in its stowed configuration.

A collapsible transport, movable between an “operative”configuration and a “stowed”configuration, said transport cart comprising: a horizontally disposed pivot member having first and second longitudinally spaced ends, said pivot member being movable up and down in a vertical plane so as to be alternately positionable in a lowered position and a raised position; first and second rigid vertical members connected to and extending upwardly from said first and second longitudinally spaced ends of said pivot member, said first and second vertical members having upper ends which are sized and configured to be grasped and lifted upwardly to cause said upward movement of said pivot member from its lowered position to its raised position; first and second rectangular floor panels having inner and outer edges; first and second side walls having upper and lower edges; a plurality of rigid transverse end members, each said end member being pivotally attached to and extending between an upper end of one of said first and second vertical members and an upper edge of one of said first and second side walls; at least one flexible strut member attached to and extending between the approximate upper edge of each of said first and second side walls and the approximate inner edge of each of said first and second floor panels, respectively; and a plurality of wheels attached to said transport cart and extending beneath said floor panels for supporting said cart on an underlying surface and for maintaining rolling contact with said underlying surface as the cart is moved between its “stowed”and “operative”configurations; said transport cart, when in its “operative”configuration being disposed such that: said pivot member is in its lowered position; said first and second floor panels extend laterally outward from said pivot member in a common horizontal plane so as to form a generally flat cargo floor; said first and second side walls extend vertically upward from the outer edges of the horizontally disposed floor panels; said rigid end members extend laterally from each said vertical member to each said side wall so as to support said side walls and to prevent inadvertent pivotal movement of said side walls relative to said floor panels; and said flexible strut members are fully extended and diagonally taut between each said side wall and each said floor panel so as to support said floor panels in their horizontal operative positions; and said transport cart, when in its “stowed”configuration, being disposed such that: said pivot member is in its raised position; said floor panels extend generally downward from the raised pivot member such that said floor members are disposed in generally vertical, side-by-side planes; said side walls are positioned outboard of and next to said generally vertically disposed floor panels; and said flexible strut members are relaxed and permitted to hang loosely from their points of affixation to said vertical members and said side walls.
