Abstract
Abstract An assembling device for two tubular profiles provided with a longitudinal slot on at least one side; two prismatic elements are provided, each intended for insertion into one of the two profiles to be assembled, blocking means for these two elements in the profiles, a rod rigidly fixed with one of the said elements engaging into a bore of the other element by traversing the longitudinal slots of the two profiles to be assembled and locking means for the rod in said other element are also present.

Assembling device for two tubular profiles provided with a longitudinal slot on at least one side, characterized in that it comprises two prismatic elements each intended for insertion into one of the two profiles to be assembled, blocking means for these two elements in the profiles, a rod rigidly fixed with one of said elements engaging into a bore of the other element by traversing the longitudinal slots of the two profiles to be assembled and locking means for the rod in said other element.
Claim 3
Dependent Claim
125 words
Device according to claim 1, characterized in that each prismatic element has a polygonal section corresponding to the section of the profile into which it is inserted, in that each element is bored at one extremity by a threaded hole intended to receive a counter-sunk locking screw accessible through the longitudinal slot of the respective profile, said screw being locked against the interior wall of the profile and in that a counter-sunk locking screw is screwed into a hole perpendicular to the bore receiving said rod, this conical locking screw being disposed endwise in the prismatic element in order to be accessible from the exterior, this screw cooperating with a recessed conical hole in order to cause the joining of the two profiles upon tightening.
