ABSTRACT:
A knockdown metal shelving assembly is disclosed. Upright frame members providing vertical series of equidistantly spaced keyhole slots are interconnected by horizontally extending shelf supports. Interconnection portions of the shelf supports are punch pressed to provide tablike projections that are inserted and retained in associated keyhole slots in the frame members. Each tablike projection includes an arcuate load-bearing portion that rests in contiguous relationship throughout its extent on a corresponding arcuate edge along the bottom of the keyhole slot. That portion of the keyhole slot receiving the load-bearing portion of the tablike projection is slightly undersized to provide an interference fit for lockably retaining the projection in the slot.
