Patent ID: 7452153

Claim:
Fitting for transverse joining of two L-shaped sections each with a web part and a foot part, separably connected to each other by said fitting with the web parts abutting back-to-back, comprising a first flange and a second flange which are J-shaped with straight back sections and bent parts, wherein the straight back section of one of the flanges is substantially parallel to the tip of the bent part of that flange, and which in mutual contact along an exterior surface of their straight back sections are slidingly connected with a connection for constituting a largely C-shaped fitting with a gap of variable length for accommodating the two foot parts of the L-shaped sections, and wherein the first flange has a first hollow for part for accommodation of one foot part without clamping action, and wherein a hollow of the second flange has a width which is less than the sum of the material thickness of the first flange at a length extending into the hollow of the second flange and the width of the first hollow at its narrowest point in order thereby to allow accommodation of the other foot part under clamping action; wherein the first flange is further provided with a first bent lug on its straight back section and wherein the first bent lug is intended for bearing against the foot parts after inserting the foot parts in the first flange and wherein the first lug has a notch for accommodating the bent part of the second flange, and wherein the notch is dimensioned for contact with the outer edge of the bent part of the second flange with an inner edge of the notch in order to prevent deflection of the bent part of the second flange when accommodating the foot parts under clamping action.
