Abstract
Abstract A one-piece load-bearing metal clip having a pair of plate-like planar elements, interconnected by a rigid integral strap, said plates being positioned in spaced parallel relation. One plate having means for connecting it to a panel and abutment means carried by the same plate adapted to bear on the free upper edge of the flange of an angle iron fastened to its support with the panel positioned generally flush against one face of the upright flange while the second plate engages the opposite face of the flange.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
A structure including a support means, panel means to be disposed in angular relationship to said support means and loadbearing means for supporting said panel in such angular relationship, including and L-shaped angle iron having its base secured to said support means and its upstanding flange angularly disposed relative to the base thereof, one-piece clip means having first and second planar elements disposed in spaced parallel relationship and interconnected at their adjacent ends by substantially rigid integral means, the first planar element having means for engaging and being fixed to said panel and abutment means for engagement with the free edge of said upstanding flange, said abutment means includes coplanar means extending axially from said first planar element in the direction of said second planar element and positioned on opposite sides of said connecting means for engaging the free edge of said flange at spaced points, said panel being adapted to be juxtaposed to one face of said upstanding flange while the second planar element of said clip engages the opposite face of said flange to retain the panel in supported and laterally restrained relationship to said angle iron.
Claim 2
Dependent Claim
189 words
A structure including a support means, panel means to be disposed in angular relationship to said support means and loadbearing means for supporting said panel in such angular relationship, including and L-shaped angle iron having its base secured to said support means and its upstanding flange angularly disposed relative to the base thereof, one-piece clip means having first and second planar elements disposed in spaced parallel relationship and interconnected at their adjacent ends by substantially rigid integral means, the first planar element having means for engaging and being fixed to said panel and abutment means for engagement with the free edge of said upstanding flange, said abutment means includes coplanar means extending axially from said first planar element in the direction of said second planar element and positioned on opposite sides of said connecting means for engaging the free edge of said flange at spaced points, said panel being adapted to be juxtaposed to one face of said upstanding flange while the second planar element of said clip engages the opposite face of said flange to retain the panel in supported and laterally restrained relationship to said angle iron.
Claim 3
Dependent Claim
36 words
A structure of the type claimed in claim 1 wherein said planar members are axially spaced and said substantially rigid connecting means has lesser width than at least one of said first and second planar elements.
Claim 4
Dependent Claim
39 words
A structure of the type claimed in claim 2 wherein said abutment means has a predetermined length of extension in the direction of said second planar element and positions said panel in a predetermined relationship to said support structure.
Claim 5
Dependent Claim
32 words
A structure of the type claimed in claim 2 wherein said flange has a predetermined thickness and said planar elements of said clip are spaced apart a distance approximating said predetermined thickness.
Claim 6
Dependent Claim
48 words
A structure of the type claimed in claim 1 wherein the means for fastening said panels includes at least one aperture in said first planar element for acceptance of a fastener having a shank and head with said shank traversing the planar element into engagement with said panel.
Claim 7
Dependent Claim
35 words
A structure of the type claimed in claim 1 wherein a plurality of angle channels are disposed in spaced relation along said horizontal support and a plurality of clips are utilized to support said panel.
