Claim 1
Independent Claim
310 words
A cart storage assembly comprising, a first cart which comprises platform means comprising a substantially flat supporting surface, a plurality of roller means mounted beneath said substantially flat supporting surface for rotation about axes which are substantially parallel to said substantially flat supporting surface, and two pairs of hollow end-supporting members extending downwardly from said substantially flat supporting surface, one pair at each end of said substantially flat supporting surface, each pair of hollow end-supporting members having substantially flat outer surfaces which are in a plane which is substantially normal to the plane of said substantially flat supporting surface, and a pair of end members, one at each end of said platform means, each end member being detachably supported by a pair of said hollow end-supporting members in a plane which is substantially normal to said substantially flat supporting surface of said platform means, a plurality of detached end members of other carts which are similar in construction to the end members of said first cart, said detached end members being positioned upon said substantially flat surface of said first cart and arranged substantially parallel to each other and substantially parallel to one of said attached end members of said first cart, and a plurality of detached platform means of said other carts which are similar in construction to the platform means of said first cart, each with one pair of its said hollow end-supporting members positioned upon said substantially flat supporting surface of said first cart, at least two of said plurality of detached platform means being arranged with their said substantially flat supporting surfaces substantially parallel to each other and to the other attached end member of said first cart, and the center of gravity of each of said latter two detached platform means residing in a vertical plane which passes through said pair of hollow end-supporting members.
