Abstract
Abstract A storage rack for holding superposed loads of palletized goods for use with a stacker crane or the like. Parallel upright trusses are spaced apart to define storage bays therebetween, and compartments within the bays are provided by rails carried by the trusses. U-shaped members connected to the columns of the trusses constitute parallel rails extending, respectively, into adjacent storage bays. Rectangular tubes may be crush-bent to the desired U-shape and connected by welds and/or brackets or supports to the columns of the trusses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A storage rack for holding superposed loads of palletized goods which comprises a plurality of upright trusses each of which contains parallel vertical columns which are interconnected by spacers rigidly affixed thereto, said trusses being arranged in parallel fore-and-aft extending planes and being laterally spaced apart from one another to define a plurality of storage bays therebetween, plurality of U-shaped load support members carried by each of said trusses at vertical intervals thereupon, each of said load supports constituting a pair of substantially parallel rails interconnected by an integral leg, each said U-shaped load support being a tube of rectangular cross section which is formed with a substantially right-angle crush-bend at each corner between said leg and each rail, first means connecting the central portion of each said leg to one of said columns and second means connecting the ends of said rails opposite from said leg to another said column in said fore-and-aft extending plane whereby rails on trusses in adjacent fore-and-aft extending planes extend into the storage bay defined thereby and provide support for palletized loads in superposed relation to one another.
Claim 2
Dependent Claim
184 words
A storage rack for holding superposed loads of palletized goods which comprises a plurality of upright trusses each of which contains parallel vertical columns which are interconnected by spacers rigidly affixed thereto, said trusses being arranged in parallel fore-and-aft extending planes and being laterally spaced apart from one another to define a plurality of storage bays therebetween, plurality of U-shaped load support members carried by each of said trusses at vertical intervals thereupon, each of said load supports constituting a pair of substantially parallel rails interconnected by an integral leg, each said U-shaped load support being a tube of rectangular cross section which is formed with a substantially right-angle crush-bend at each corner between said leg and each rail, first means connecting the central portion of each said leg to one of said columns and second means connecting the ends of said rails opposite from said leg to another said column in said fore-and-aft extending plane whereby rails on trusses in adjacent fore-and-aft extending planes extend into the storage bay defined thereby and provide support for palletized loads in superposed relation to one another.
Claim 3
Dependent Claim
61 words
A storage rack in accordacne with claim 1 wherein said trusses each contain a plurality of vertically-spaced supports which extend laterally outward from said other column for supporting the rail portions of said U-shaped members at different vertical levels and which constitute said second connecting means, said rails each resting upon said supports at a location near the free ends thereof.
Claim 4
Dependent Claim
37 words
A storage rack in accordance with claim 2 wherein said first connecting means comprises weld means joining said leg at about its midpoint to said one column and wherein said rails are welded to said laterally-extending supports.
