Abstract
Abstract A jointing device for securing a horizontal frame member to a vertical frame member comprises a strip having its longitudinal ends extending beyond the vertical width of the horizontal frame member and including a central portion extending substantially over said vertical width. There are provided first holes formed through the central portion of the strip and second holes formed adjacent the longitudinal ends of the strip. The strip is first screwed to a longitudinal edge of the horizontal frame member through the first holes and then screwed to an inner wall of the vertical frame member through the second holes, thereby coupling the frame members together.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
198 words
A T-shaped structural joint, comprising: a. a horizontal tubular rail having a rectangular hollow cross-section, there being means defining a pair of elongated tapped sockets whose thread axis extends parallel to the length of said horizontal rail and said means being integral therewith at its upper and lower narrower interior surfaces; b. a vertical tubular member having a rectangular hollow cross-section, there being a pair of flanges extending along opposite edges of and perpendicularly to one of the narrow sides of said vertical members, there being a pair of tapped holes in said one side of said member spaced apart by a distance greater than the vertical height of said rail, and disposed at an intermediate location along the height of said member; c. a strip having a surface, which is flat throughout the extent of such strip, disposed flatwise against said one side of said member between said flanges and having apertures in registration with said tapped holes, said tubular rail engaging the opposite surface of said strip between said apertures, said strip having further apertures in registration with said tapped sockets; and d. screws passing through said strip into said tapped holes and said tapped sockets.
Claim 2
Dependent Claim
198 words
A T-shaped structural joint, comprising: a. a horizontal tubular rail having a rectangular hollow cross-section, there being means defining a pair of elongated tapped sockets whose thread axis extends parallel to the length of said horizontal rail and said means being integral therewith at its upper and lower narrower interior surfaces; b. a vertical tubular member having a rectangular hollow cross-section, there being a pair of flanges extending along opposite edges of and perpendicularly to one of the narrow sides of said vertical members, there being a pair of tapped holes in said one side of said member spaced apart by a distance greater than the vertical height of said rail, and disposed at an intermediate location along the height of said member; c. a strip having a surface, which is flat throughout the extent of such strip, disposed flatwise against said one side of said member between said flanges and having apertures in registration with said tapped holes, said tubular rail engaging the opposite surface of said strip between said apertures, said strip having further apertures in registration with said tapped sockets; and d. screws passing through said strip into said tapped holes and said tapped sockets.
Claim 3
Dependent Claim
16 words
A T-shaped structural joint according to claim 1, said opposite surface of said strip being flat.
Claim 4
Dependent Claim
61 words
A T-shaped structural joint according to claim 1, said opposite surface of said strip having a portion, through which said further apertures pass, which is thicker than the remaining portion of said strip whereby the end of said tubular rail is offset from said one side of said member by a further amount corresponding to the added thickness of said strip.
