Abstract
Abstract A shelving system with an improved shelf to post support assembly that permits the support of heavy shelf loadings, yet easy separation of the support assembly as well as an elimination of racking. The support assembly, positioned at each corner of each shelf, includes a one piece, split ring insert member and a corner section fixed to the shelf. The insert member is independently positioned on the post at a desired position and is comprised of an upper portion having a cylindrically shaped wall section defining a substantially cylindrical interior bore and a cylindrical outer wall. The lower section is radiused outwardly beyond the outer cylindrical wall and the interior bore extends therethrough and includes a radially inwardly directed rib. The corner section has a through bore including upper and lower cylindrical wall sections, the lower having a greater diameter with a chamfered surface serving to connect the upper and lower sections together. The top end of the upper section is tapered inwardly to define an opening substantially equal to, but not greater than the outer diameter of the insert member's cylindrical wall section and the diameter of the upper and lower cylindrical bores are each greater than the outer diameters of the cylindrical and radiused portions of the insert. When assembled, the chamfered surface will engage the radiused portion of the insert, the top opening of the corner section will engage the insert and each will be spaced from the other along the remaining adjacent wall sections.
