ABSTRACT:
An injection molded, foam plastic, knock-down display stand. The display stand is formed from two major components. A V-shaped longitudinal member supports the shelves. The shelf supports have a number of open ended parallel slots. Joining two shelf supports together forms an X-shaped, free-standing shelf support column. Each shelf has an X-shaped opening to receive the shelf support column. Rotating the shelf through the slots joins the shelf to the shelf support column. Integral camming surfaces on the shelves lock the shelves and the shelf supports together to form a substantially erect display stand.
