ABSTRACT:
A light-weight modular utility cart has first and second identical side members which are preferably one-piece, molded plastic structures. Each side member may include a plurality of bottom projections which interlace with complementary bottom projections from another side member to form the cart bottom. The side members include structure for mounting thereto top members having different configurations. Alternatively, a single top configuration can be mounted on assembled different side member configuration having different heights. Each side member includes a plurality of upwardly-angled drawer rails on an inside surface thereof. The drawers may include identical first and second rollers each having a circumferential groove in the center thereof adapted to ride on an uppermost edge of the upwardly-angle drawer rail. Accessories may be attached to the cart through a tubular support structure, U-shaped channels, and a two-piece coupler having different size holes therein. The result is a modular utility cart that may be adapted to a wide variety of uses, yet is easy to manufacture and assemble.
