Abstract

Abstract An improved shelf which may be easily assembled and disassembled and wherein a plurality of units may be vertically and horizontally arranged is disclosed. The improved shelf includes at least one bottom board having a plurality of upwardly extending pillars extending from corners of the bottom board and formed integrally therewith. Each pillar has an inner downwardly curved side extending toward a downwardly curved side of another pillar. The bottom board has a hollow region adjacent the curved side of each pillar. The hollow region has an aperture therein through which a fastener may extend. The bottom board also has indented regions in the bottom thereof and integrally formed therewith which are used for vertical stacking of shelf units. A plurality of side boards are provided. Each has a set of vertically extending grooves integrally formed along the sides thereof. A set of internally threaded sleeves are positioned within the grooves and integrally formed with the side board and a set of downwardly extending curved members are integrally formed with said side board, one downwardly curved member extending from each groove. The curved members correspond in shape to the downwardly curved side of the pillars and each member has a leg portion adapted to fit within the hollow region adjacent each pillar. The leg portion has an aperture which is adapted to overlay the aperture in the hollow region of the bottom board when the leg is positioned within the hollow region. A set of support members extend upwardly from the top of the side board coaxially of each groove and are open on the same side as the grooves. A cover member fits over each groove. The cover members have apertures corresponding to the internally threaded sleeves and fasteners may be inserted therethrough. Each cover member has a hook member extending from an end thereof. The hook members are positioned within the upwardly extending support member and extend outwardly through the open side thereof. A top board is provided. The top board has a region in the bottom thereof adapted to receive the upwardly extending members of the side board. The region also has an indented section which receives the hook member for firmly connecting the top and side boards.
