Framework assembling members

Claim 1

Member for assembling one end of a tubular element to a section element formed with at least one plane sidewall consisting of spaced flanges defining a semi-closed slot; the said member being essentially constituted by a stem carrying an oblong head formed with parallel flanks; said stem being adapted to be fitted axially into said end of said tubular element and secured therein by a set screw located at a predetermined distance from said end; said head being adapted to be inserted at any desired point into said slot when positioned parallely thereto, and then to be locked under said flanges by being given substantially a quarter turn for being positioned substantially transversely of said slot; characterized in that said set screw is engaged in a large-pitch helical groove extending substantially over a quarter turn round said stem and terminating in a locking cavity located adjacent to said head at a distance therefrom substantially equal to said predetermined distance; whereby said head can be successively inserted into said slot, given said quarter turn and locked under said flanges by a single operation consisting in pressing said end of said tubular element onto said sidewall of said section element; the location and shape of said locking cavity on said stem being such that tightening of said set screw therein ensures the clamping of said flanges between said end of said tubular member and said head of said assembling member.
