ABSTRACT:
The shelving system includes a plurality of shelves each having square shelf openings at each corner. A plurality of leg supports in turn have upper end portions receivable in the bottom of the shelf openings and lower end portions receivable in the top of the shelf openings and within the upper end portions of the leg supports positioned in the bottom of the shelf openings so that the upper end portions of legs are nested in the shelf openings and the lower end portions of legs extending into the top of the shelf openings are nested within the upper end portions of these legs. Any number of successive shelves can be assembled to the top end portions of the upper legs. The nested square shelf opening, upper end portion of a leg and lower end portion of another leg at each corner are secured or mechanically locked by manually passing a clip through the nesting side walls. Towards this end there are provided windows in the nested side walls which are in registration when the leg members and shelves are properly assembled for receiving the clip. Any desired shelving configuration according to a user's wishes can thus be assembled and/or disassembled without the need of tools.
