ABSTRACT:
In a shelving unit having a two-piece upright with a sloping slotted lower part and a vertical slotted upper part telescoping into the lower part, the slots in the upper part are recessed behind the upper end of the slotted portion of the lower part to allow room for shelf tabs projecting through the slots in the lower part near the upper end thereof. A shelf bracket may be mounted at the transition between the lower and upper parts of the support with its upper tab in a slot in the upper part and with one or more of its lower tabs projecting through slots in the lower part. The slots of the two parts are positioned relative to each other so that the lower tabs project through their slots in the lower part of the support and abut the recessed slotted surface of the upper part, which extends downwardly behind the slotted surface of the lower part. In this way a shelf spanning the transition is situated at the same angle as a shelf supported entirely on the upper part. The shelf tabs are also designed with steps, and the slots of the sloping face of the lower part are spaced farther apart from each other than the slots of the vertical face of the upper part. Thus a shelf supported entirely on the lower part also assumes the same angle as shelves on the upper part or at the transition.
