ABSTRACT:
An improved merchandise display structure of the type having upright posts and transverse connecting struts, each post having longitudinal series of mounting slots in the bottoms of grooves formed in the sides of the posts to receive hanger brackets and other display accessories as well as panels that can be supported in the grooves in the posts and the struts. The preferred post construction is formed by two identical one-piece strips of lightweight sheet metal that are of generally V-shaped cross-sectional shape, each forming two grooved sides of a square post. The opposite longitudinal edges of each strip are formed as a channel-shaped bend and a tongue for interfitting with the channel-shaped bend of the other strip when turned end-for-end, and are secured together in a stitching operation. Each V-shaped strip has a channel-shaped corner bend simulating a tongue-and-groove joint for symmetry and extra strength. To adapt the lightweight material for use with standard slot hardware designed for heavier material, the end of each slot in the bottom walls of the grooves may be offset to double the effective wall thickness of the material as well as to increase its strength. The method of the invention provides an elongated multiple-length strip of the bent material, cuts the strip into a plurality of post-length strips, pairs off the strips and turns one end-for-end, and stitches the strips together. A second embodiment of the invention uses four substantially flat one-piece strips, each having a central groove, a channel-shaped bend along one edge and a tongue along the other, two of the four strips being turned end-for-end before stitching. Optional decorative corner covers are provided in different corner shapes to be slid onto the posts. The preferred lightweight sheet metal is sixteen gauge (about 0.060 inch), which can be used with standard slot hardware designed for either sixteen gauge or the heavier eleven gauge (about 0.120 inch). The groove bottom walls at the opposite ends of the slots are offset and effectively doubled in thickness for standard eleven-gauge hardware.
