Abstract
Abstract A collapsible carry-all cart includes a frame which is provided with side rod members that are retractable to thereby selectively collapse or extend the cart in a front to rear direction. The frame has a pair of legs with wheels mounted thereon at each side thereof. The pairs of legs are pivotable in scissor-like fashion and are slidable vertically on the frame from an extended position in which the cart is rollable on the wheels to a storage position in which the pairs of legs are shifted to an upper position. A handle element extends upwardly from the rear of the frame, and a cover member is secured to the frame in order to provide a storage compartment. An accordion-type pocket is integral with the cover at the front of the cart.
