Articulation tongue and fixation tongue coupling device for articulating panel, has complementary forms allowing position adjustment and blocking of fixation tongue under stress of screw that is cooperated in support on articulation tongue

摘要

The device has a coupling brace with a T shaped profiled groove that surrounds a transverse section of a fixation tongue (2). The groove and a part of the section present relief and hollow complementary forms (2g, 3e) such as asperities, for allowing the position adjustment and position blocking of the tongue with respect to the brace under a tightening stress of a cone-point set screw, where the asperities are constituted by tooth. The screw is engaged in the thickness of the brace and cooperated in support on an articulation tongue (1) corresponding to the overlapping of the forms.
