ABSTRACT:
A shelf is supported by at least one shelf support from at least one vertical support having vertically spaced slots therein. The rear edge of each shelf support carries upper and lower extensions which fit into the slots. Abutting surfaces between the upper and lower extensions extend at angles to each other and abut, selectively, the adjacent surface of the vertical support. A downwardly opening notch in the lower edge of each upper extension engages the adjacent portion of its vertical support between the slots therein while the shelf is horizontal. An upstanding projection on the upper edge of each upper extension engages the adjacent portion of its vertical support between the slots therein while the shelf is tilted. Depending projections on the lower extensions abut adjacent portions of the vertical support between the slots therein while the shelf is horizontal and are adapted to move over the portions of the support between the slots upon upward movement of the rear portion of the shelf.
