Fixture is used in a plastered-in door or window frame, using eccentric discs rotating about axes parallel to the plane of the opening, engaging in groove-shaped seatings and pressing the frame against an outer stop. The groove is fitted in the part of the frame facing inwards. On each eccentric disc is a firmly connected cylindrical shaft, forming its axis of rotation, and held in a hole in the frame, the neck section of this is of polygonal shape, where it joins the eccentric disc and is accessible through the gap which is open during the assembly process, between frame and seating. This makes it possible to provide an invisible fixture for a single-part frame, with simple assembly procedure, as well as for frames in two parts. |
