ABSTRACT:
The nut and bolt connection between bent metal columns and shelves: is easy to assemble because the bolt apertures through the shelf skirts are spaced downwardly from the shelf main planar support surface a distance sufficient to permit easy finger access for the nut; is easy to assembly because the skirt includes a return bend portion forming an upwardly facing nut locking surface to prevent rotation of the nut during assembly; is secure because the skirt is formed of spaced apart walls that will compress and bias the nut, bolt assembly, particularly with an interlocking upper portion of the walls to provide for symmetrical compressions; is secure due to the columns being biased or stressed during assembly to bias the nut and bolt threads; and is strengthened in the column margins by bent portions that also increase safety.
