  • Patent number: 4262439
    Abstract: A free-standing display system comprising a base, an upright post supported from the base and a plurality of shelves mounted on the post, is described. Each of the shelves has an opening dimensioned and shaped to fit freely around the post. The shelves are securely mounted on the post at desired height by means of wedges releasably held on the post by lugs which engage corresponding holes in the post. With the wedges in place, the shelf is moved downwardly around the post until the walls of the shelf opening, which are inclined to match the wedging surface of the wedges, snugly engage the wedging surfaces. Differently shaped and dimensioned shelves may be employed in the system and the shelf opening may be at the shelf centers or adjacent an edge. No tools are required to assemble or disassemble the shelves to the post. A header may be fastened to the upper end of the post, after the desired number of shelves are in place, to carry product identifying indicia or an advertising message.
