Abstract
Abstract An extruded structural member having a first pair of spaced apart flanges projecting from a face of the member and a second pair of spaced apart flanges projecting from another face of the member. The flanges are dimensioned such that one of the pairs will fit slidably between the other of the pairs on another member of similar configuration when connecting two such members together. Each flange of one of the pairs of flanges has a longitudinally extending ledge thereon, the ledges facing towards the member, and each flange of the other pair of flanges has a tab struck out therefrom and adjacent one end of the member providing an edge extending at an angle with respect to the ledges. In assembling two such members at an angle, the edges on one of the members engage with the ledges on another to hold the two members together in a predetermined angular relationship.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
274 words
An extruded structural member including an elongated structural element with two longitudinally extending side faces directed away from one another, a pair of spaced apart longitudinally extending first flanges integral with said element and projecting from one of the side faces thereof and a pair of spaced apart longitudinally extending second flanges integral with said element and projecting from the other side face thereof, with said first flanges having inner mating faces spaced apart a first predetermined distance and said second flanges having outer mating faces spaced apart by said first predetermined distance such that the second flanges of one such member will fit slidably between the first flanges of another such member and with each flange of one of said pairs of flanges having a ledge in its mating face, the ledges extending the length of the flange facing towards the adjacent side face of the member and spaced therefrom a second predetermined distance throughout the length of the flange, each flange of the other pair of flanges having a resilient projection integral therewith, projecting from its mating face, each such projection having a free edge spaced from an end of the structural element by said second predetermined distance, facing away from said end and extending across the associated mating faces in a direction transversely to said side faces of said structural element so that in assembling two such structural members with said end of one abutting against said one side face of the other, the edges of the resilient projections of the one will engage under the ledges of the other to hold the two members together at a predetermined angular relationship.
Claim 2
Dependent Claim
274 words
An extruded structural member including an elongated structural element with two longitudinally extending side faces directed away from one another, a pair of spaced apart longitudinally extending first flanges integral with said element and projecting from one of the side faces thereof and a pair of spaced apart longitudinally extending second flanges integral with said element and projecting from the other side face thereof, with said first flanges having inner mating faces spaced apart a first predetermined distance and said second flanges having outer mating faces spaced apart by said first predetermined distance such that the second flanges of one such member will fit slidably between the first flanges of another such member and with each flange of one of said pairs of flanges having a ledge in its mating face, the ledges extending the length of the flange facing towards the adjacent side face of the member and spaced therefrom a second predetermined distance throughout the length of the flange, each flange of the other pair of flanges having a resilient projection integral therewith, projecting from its mating face, each such projection having a free edge spaced from an end of the structural element by said second predetermined distance, facing away from said end and extending across the associated mating faces in a direction transversely to said side faces of said structural element so that in assembling two such structural members with said end of one abutting against said one side face of the other, the edges of the resilient projections of the one will engage under the ledges of the other to hold the two members together at a predetermined angular relationship.
Claim 3
Dependent Claim
33 words
The structural member of claim 1 wherein said ledges are formed in said inner mating faces of said fIrst flanges, and said projections project from the outer mating faces of the second flanges.
Claim 4
Dependent Claim

The structural member of claim 2 wherein said structural element is of hollow rectangular cross-section and includes a first web having said two side faces and a diametrically opposed second web, said first flanges projecting from the outwardly directed one of said side faces of said first web and the second flanges projecting from the inwardly directed one of said side faces of said first web, said member further including a pair of spaced apart longitudinally extending third flanges integral with said structural element projecting inwardly from said second web, each said third flange being aligned with a respective one of said second flanges and a resilient projection integral therewith, projecting from a mating face thereof, the projections having free edges spaced from said end of the structural element by said second predetermined distance, facing away from said end and extending across the associated mating faces in a direction transversely to said side faces of said structural element, said member also including a pair of spaced apart longitudinally extending fourth flanges projecting outwardly from said second web, said fourth flanges having the same configuration as and being aligned with said first flanges.
Claim 5
Dependent Claim
192 words
The structural member of claim 2 wherein said structural element is of hollow rectangular cross-section and includes a first web having said two side faces, a diametrically opposed second web and a third web connecting said first and second webs, the first flanges projecting from the outwardly directed one of said side faces of said first web and the second flanges projecting from the inwardly facing one of said side faces of said first web, said member further including a pair of spaced apart longitudinally extending third flanges projecting inwardly from said second web, each said third flange being aligned with a respective one of said second flanges and a resilient projection integral therewith and projecting from an outer mating face thereof, the projections having free edges spaced from said end of the structural element by said second predetermined distance, facing away from said end and extending across the associated mating faces in a direction transversely to said side faces of said structural element, said member also including a pair of spaced apart longitudinally extending fourth flanges projecting outwardly from said third web and being substantially the same as said first flanges.
Claim 6
Dependent Claim
38 words
The structural member of claim 2 wherein said structural element is substantially L-shaped in cross-section including a first web having said two side faces and a second web integral with said first web and extending angularly away therefrom.
Claim 7
Dependent Claim
