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. Loading of the shelf develops oppositely-directed forces on the tabs at the aperture edges, with the oppositely-directed forces acting edge-on on the edges of the self-locking tabs in each aperture, in shear, insuring a very high overall system load capability.
