Abstract
Abstract For use in joining the mitered ends of a pair of members having pockets, a corner gusset with a stem zone to overlay the mitered line of juncture and having a pair of legs and a pair of arms, with one of the legs and one of the arms extending generally in a common direction from the stem and the other of the arms and legs extending oppositely from the stem so that the legs are adapted to be received in the pockets at the end of the members to be joined in snug relation and the arm is adapted to clampingly embrace the sidewalls of the pocket so that the members joined cannot be separated and resist flexing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
268 words
For joining the mitered ends of a pair of members of longitudinally uniform cross section at their respective end portions, each of said end portions defining a longitudinally extending pocket when the mitered edges are in confronting engagement, and each pocket having an inner wall and an opposite outer wall, each of said walls having an inner surface in the pocket and an outer surface, a corner gusset having a body of uniform cross section including a stem zone defining a line of symmetry to overlay the mitered line of juncture of the members when the mitered surfaces are in abutting engagement, and a pair of diverging arms and a pair of diverging legs, with one of the legs and one of the arms extending generally in a common direction from the line of symmetry and at an angle of 45* with respect to said line, and the other of said arms and of said legs extending oppositely respectively from the said one of the arms and said one of the legs, with one of the legs being adapted to be received in the pocket of one of the end portions, said one of the legs having a portion sized to span the dimension of the pocket between the inner surfaces to abuttingly engage the inner surfaces of the walls, and with said one of the arms extending in the common direction being arranged on the body such that is overlays the outside surface of the outer wall of the pocket in close embracing relation, each leg being sized for snug reception in the pockets of the members.
Claim 2
Dependent Claim
268 words
For joining the mitered ends of a pair of members of longitudinally uniform cross section at their respective end portions, each of said end portions defining a longitudinally extending pocket when the mitered edges are in confronting engagement, and each pocket having an inner wall and an opposite outer wall, each of said walls having an inner surface in the pocket and an outer surface, a corner gusset having a body of uniform cross section including a stem zone defining a line of symmetry to overlay the mitered line of juncture of the members when the mitered surfaces are in abutting engagement, and a pair of diverging arms and a pair of diverging legs, with one of the legs and one of the arms extending generally in a common direction from the line of symmetry and at an angle of 45* with respect to said line, and the other of said arms and of said legs extending oppositely respectively from the said one of the arms and said one of the legs, with one of the legs being adapted to be received in the pocket of one of the end portions, said one of the legs having a portion sized to span the dimension of the pocket between the inner surfaces to abuttingly engage the inner surfaces of the walls, and with said one of the arms extending in the common direction being arranged on the body such that is overlays the outside surface of the outer wall of the pocket in close embracing relation, each leg being sized for snug reception in the pockets of the members.
Claim 3
Dependent Claim
161 words
The corner gusset as set forth in claim 1 wherein each leg includes structure defining a first surface extending from the stem zone to the outer wall of the pocket, said first leg surface terminating at a knee comprising one of said abutment surfaces and adapted to abuttingly engage the inner surface of the outer wall, each of the arms having a surface facing the stem and adapted to overlay the outer surface of said outer wall, said surface being spaced from said surface of abutment of said knee a distance substantially equal to that thickness of said outer wall means to embrace said outer wall when the associated leg is in the pocket nestled against the inner surface of the outer wall, the intersection of the arm and the stem zone defining a recess to receive the terminal end of the outer wall of the member when the gusset plate is joining a pair of tubular members at mitered ends.
Claim 4
Dependent Claim
43 words
The gusset plate as set forth in claim 2 wherein the distal end of each of said arms extends toward, but not as far as, the abutment surface of the knee of the associated leg extending in the same direction from said body.
Claim 5
Dependent Claim
38 words
The gusset plate as set forth in claim 1 having a recess on opposite sides of the stem zone intermediate the terminal end of each of the arms and the portion of the leg which abuts the member.
Claim 6
Dependent Claim
69 words
The gusset plate as set forth in claim 4 wherein each of said legs includes an upper leg portion with a first surface extending to the inner surface of the outer wall of the pocket on said upper leg portion and a lower leg portion extending from the first leg to the inner surface of the inner wall, the zone of juncture of said upper leg comprising said knee.
Claim 7
Dependent Claim
31 words
The gusset plate as set forth in claim 2 wherein the recess receives the terminal end of the outer wall of the pocket and comprises a recess in said first surface.
Claim 8
Dependent Claim
29 words
The gusset plate as set forth in claim 1 in combination with a mitered length of extruded material, and one of said leg means snugly nested in said pocket.
Claim 9
Dependent Claim
54 words
The combination as set forth in claim 7 including a second member of similar size and configuration to that of said first member and having a mitered end and the other of said legs extending into said pocket, said gusset plate defining a corner joint together with the mitered end portions of said members.
Claim 10
Dependent Claim
24 words
The gusset plate as set forth in claim 1 wherein the abutment surfaces are enlarged comprising a foot to distribute load on the walls.
Claim 11
Dependent Claim
26 words
The combination as set forth in claim 7 wherein the outer wall means is deformed into said recess to stake the gusset plate to the member.
