Cantilever rack

Claim 1

A cantilever storage rack structure comprising an elongated vertical standard having a front surface, a pair of side surfaces extending rearward from said front surface and a re-entrant surface extending inward from the rear end of each of said side surfaces, and a cantilever support arm having an inner end for attachment to said standard so that it extends from said front surface thereof and an outer end that will be spaced from said standard, which arm includes a pair of elongated generally horizontal tubular members and means joining said elongated members together at at least spaced points generally adjacent said outer end of said support arm and thereby causing said elongated members to normally lie in contiguous relationship at said inner end of said support arm, and which support arm also includes a bracket affixed to the inner end of each of said elongated tubular members for attaching said support arm to said standard, said brackets each having a first flange portion for abutting said front surface of said standard when attached thereto, a second portion extending rearward from said first flange and a re-entrant flange element extending from said second bracket portion in the same direction as said first flange and generally abutting said re-entrant flange of said standard, said elongated members being unconnected to each other for a substantial distance adjacent the inner end of said support arm and the free edges of said re-entrant flange elements being so spaced apart that, when one said flange element is located in contact with one said re-entrant surface of said standard and said cantilever arm is rotated, said tubular members are resiliently spread apart as a result of said rotation to an open condition and thereafter snap back together in partially circumscribing relationship about said standard at a location intermediate its upper and lower ends, said support arm tubular members even when loaded remaining in said snapped together condition without additional attachment.
