Claim 1
Independent Claim
323 words
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.

Claim 3
Dependent Claim
37 words
A structure in accordance with claim 1 wherein said standard and at least one of said brackets are provided with interengaging means, said interengaging means preventing downward movement of said support arm when attached to said standard.
Claim 4
Dependent Claim
27 words
A structure in accordance with claim 2 wherein said interengaging means includes an aperture and a protuberance, said protuberance being adapted to be received in said aperture.
Claim 5
Dependent Claim
49 words
A structure in accordance with claim 1 wherein said standard has a pair of side surfaces which extend rearward from said front surface which side surfaces of said standard are provided with apertures and wherein said reentrant means on said bracket comprises lugs which are received by said apertures.
Claim 6
Dependent Claim
38 words
A structure in accordance with claim 1 wherein said re-entrant surfaces are substantially parallel to said front surface of said standard and wherein said first flange portion and said re-entrant flange of said bracket are likewise substantially parallel.
Claim 7
Dependent Claim
27 words
A structure in accordance with claim 1 wherein said elongated members are unconnected for a distance from the midpoint to the inner end of said support arm.
Claim 8
Dependent Claim
33 words
A structure in accordance with claim 6 wherein said points of joinder of said elongated members span a distance at least equal to about 10 percent of the length of said elongated members.
Claim 9
Dependent Claim
41 words
A structure in accordance with claim 1 wherein said arm includes brace means near the inner end thereof which extends diagonally downward from each of said elongated members to said bracket and also provides a support surface to retain horizontal decking.
Claim 10
Dependent Claim
22 words
A structure in accordance with claim 1 wherein said standard has the cross sectional shape of the general outline of an ''''I.''''
