FOLDABLE SHELVING CONSTRUCTION

A shelving unit adapted for attachment to a vertical surface (18) has a plurality of square cross-section tubes that are to be attached vertically the surface (18). The tubes have slots (38) arranged in horizontal pairs in vertically spaced relation along the length of the tubes. Fitted into the slots (38) are L-shaped steel plates (32) having first and second legs (34). The first legs (34) are pivotally mounted within the tubes to swing through the slots (38). A stop is provided causing the second leg to extend perpendicularly to a front side of the square tubes. Sandwiched between the second legs (34) of each adjacent pair of plates (32) are shelf supports for rectangular shelves (28). The pivotal mount of the plate pairs allows a shelf to be shifted from a horizontal and vertical disposition. Spring latches attached to the tubes serve to releasably secure the shelves (28) in their vertical disposition.
