Abstract: A shelving support system using a locking tab and aperture arrangement, in which an upright member is provided with a pair of rhombic-shaped apertures formed one above the other, each aperture being oriented at 45 degrees to the vertical. The pair of apertures engages a pair of tabs protruding from a shelf support, with orientation matching the apertures, to maintain locking engagement by developing oppositely-directed forces on the tabs, when the support is attached to the upright in cantilever fashion. The attachment is achieved by engagement of the tabs in the apertures first, and then the support is locked via combined horizontal and vertical, diagonally-directed motion. The 45 degree orientation of the apertures enables the upright members to be left and/or right handed, since the reverse side of the apertures is a mirror-image, so that the shelf supports are attachable on this side also, thus reducing the total number of individual components needed for system assembly.

Abstract: A sturdy, easily constructed shelving support system for homes, stores and offices. The system uses shelf hangers and wall brackets, employing a novel, push-fit interlocking connector. The shelf hanger is fabricated as a rigid wire member, bent into a V-shape and connected at its ends to a right angled upright member by the push-fit connector locked into a square opening formed In the upright. The lower leg of the shelf hanger is suspended by the support leg, with its end portion flush against the upright wall, so that It does not rotate, to provide a stable support for a shelf end. The push-fit connectors are easily locked into the openings In the upright member, and may be quickly removed and re-positioned, enabling quick and easy construction of an entire shelving system within minutes, or easy alteration of its layout. A feature of the invention is that in addition to its support function, the support leg acts as a shelf book-end.

Abstract: A modular unit for a shelving system includes a pair of tube connectors each made up of half-sections together having an outer transverse dimension slightly less than the inner transverse dimension of a tube to be connected thereto, a threaded fastener threaded through an opening in one half-section and abutting the other half-section to force apart the two half-sections and thereby to firmly clamp them to a tube, and a tie rod joining a half-section of one of the tube connectors to a half-section of the other tube connector.
