Abstract
An adjustable shelf unit for use in a storage rack and having at least two shelf panels supported on laterally spaced forwardly extending support members. Each panel is slidable over the panel behind it and each panel but the front panel has a indentation across its forward edge the depth of which is equal to the thickness of a transversely extending lip on the rear of the panel in front of it. The side flanges of the panels have tabs which engage one another when the panels are extended to limit the forward travel of the panels. Also disclosed is a cable which is looped around sheaves fixed to the support members. The cable is fixed to each side of the front panel so as to maintain proper alignment of the panels.
