Abstract
Abstract A frame assembly is disclosed for supporting a panel which together with the frame provides a partition or divider structure. The frame assembly includes a pair of upright frame members of extruded aluminum and a pair of horizontal frame members of extruded aluminum. The upright members are provided with opposed pairs of polygonal openings therethrough, and the horizontal members include a tubular portion complementary in polygonal cross-section and dimension with respect to the openings in the upright members. Expandable fasteners of complementary cross-section are inserted through the openings and expanded to interconnect the horizontal and vertical members. The horizontal members include integral pairs of flanges providing opposed recesses for receiving corresponding edges of a panel supported by the frame assembly.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
237 words
A panel supporting frame assembly comprising, first and second pairs of parallel spaced apart frame members, said first pair of frame members having walls facing one another and provided with aligned polygonal openings therethrough, said second pair of frame members being extruded metal members having opposite ends juxtaposed with respect to said walls and provided with polygonal openings thereinto aligned with said openings through said walls, expandable fastener means extending through said openings in said walls and into the openings in the ends of said second pair of frame members, each of said second pair of frame members including a pair of longitudinally extending laterally spaced apart flanges integral therewith and defining a panel edge receiving recess therefor, said recesses of said second pair of frame members opening toward one another and being spaced apart to receive and support a panel therebetween, said fastener means having first portions in said wall openings, second portions in said second member openings and means engaging said walls to axially position said first and second portions in said openings, said first and second portions being of complementary polygonal cross-section and dimension with respect to the corresponding wall and second member openings, said second portion of each said fastener means including a plurality of legs in the corresponding second member opening, and each said fastener means further including wedge means engaging and spreading said legs radially against said corresponding second member opening.
Claim 2
Dependent Claim
237 words
A panel supporting frame assembly comprising, first and second pairs of parallel spaced apart frame members, said first pair of frame members having walls facing one another and provided with aligned polygonal openings therethrough, said second pair of frame members being extruded metal members having opposite ends juxtaposed with respect to said walls and provided with polygonal openings thereinto aligned with said openings through said walls, expandable fastener means extending through said openings in said walls and into the openings in the ends of said second pair of frame members, each of said second pair of frame members including a pair of longitudinally extending laterally spaced apart flanges integral therewith and defining a panel edge receiving recess therefor, said recesses of said second pair of frame members opening toward one another and being spaced apart to receive and support a panel therebetween, said fastener means having first portions in said wall openings, second portions in said second member openings and means engaging said walls to axially position said first and second portions in said openings, said first and second portions being of complementary polygonal cross-section and dimension with respect to the corresponding wall and second member openings, said second portion of each said fastener means including a plurality of legs in the corresponding second member opening, and each said fastener means further including wedge means engaging and spreading said legs radially against said corresponding second member opening.
