Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
Framing for shelves incorporating sections of elongated slotted channel members and apertured L-shaped corner pieces fastened thereto so as to form vertical and horizontal supports for a plurality of shelves, said elongated channel members having a transversely arcuate base portion and oppositely disposed longitudinally extending cross sectionally arcuate flanges joining said transversely arcuate base portion in continuously curving sections and oppositely coplanar outwardly extending continuous substantially flat edge flanges on said arcuate flanges, said L-shaped corner pieces each having an arcuate base portion and arcuate flanges which curve outwardly from said corner piece base portion to define a configuration corresponding to that configuration of said channel members mating with said channel members for intimate contact therewith in nesting relation with said corner piece base received in said channel member base so that said base members contact each other and corresponding ones of said flanges contact each other, said nested, correspondingly configured corner pieces and channel members adding rigidity and shear strength to the framing.
