ABSTRACT:
A corrugated board display structure has tabs for readily connecting a horizontally extending shelf to an upright support in such a manner that the load capacity of the shelf is significantly increased. Edge segments formed in an upright, folded portion of the shelf bear directly in end-to-end engagement with edge segments adjacent upstanding tabs of an upright support, and the depending tabs of the upright portion connected to the shelf are received behind the upstanding tabs of the upright support in order to thereafter retain the edge segments in continuous, flat contact. The longitudinal axes of the ridges and grooves of the corrugated panel forming the upright support are in generally parallel relationship to the longitudinal axes of ridges and grooves of the corrugated panel comprising the upright portion, so that the columnar strength presented by the corrugations of the support resist the load presented by the corrugated upright portion without bending of either corrugated panel in lateral directions. Preferably, an inclined, intermediate portion interconnects the shelf and the upright portion, and the shelf includes a bottom layer which extends beneath the intermediate portion and contacts the upright support to thereby present a horizontally extending, triangular beam which further enhances the load-bearing capacity of the display.
