Definitions
- the invention relates to a fitting for fastening a frame in a wall opening with a holder for fastening to a frame and with a first clamping bracket and a second clamping bracket, which are slidably guided in order to change the span of the clamping bracket, with the first clamping bracket on the Bracket and the second clamping bracket is slidably guided on the first clamping bracket.
- a fitting has become known, for example, from EP 3 540 165 A1.
- the holder is formed by a holding plate which covers the two clamping brackets with a central surface. Two guide elements cut out on the side of the retaining plate are used to guide an outer clamping bracket, on which in turn an inner clamping bracket is slidably guided.
- the invention is based on the object of specifying an alternative fitting for fastening frames.
- the holder is designed as a rail with at least one rail section, which is gripped over and under by guide sections of the first clamping angle, in order to hold the first clamping angle on the rail and guide it in a displaceable manner .
- the rail advantageously has rail sections on both sides, which are gripped over and under by the guide sections of the first clamping angle, in order to hold the first clamping angle on the rail and guide it in a displaceable manner.
- the rail is particularly preferred as a II, I or trapezoidal profile with profile ends angled outwards or inwards, which are gripped over and under by the first clamping bracket, as a semi-circular profile with curved profile ends, which are gripped over and under by the first clamping bracket, or as a U-profile with profile grooves provided in the two side legs of the U-profile, in which the first clamping bracket engages.
- the first clamping bracket has a carriage that is slidably guided on the rail and an angle element.
- the carriage and the angle element can be manufactured together as a single part or as two separate parts which are fastened together.
- the two-part design of the first clamping bracket, consisting of the bracket element and the carriage has the advantage that carriages and rails of different lengths can be selected depending on the wall or wall thickness, in order to provide a fitting with a suitable length in each case.
- the second clamping angle can in turn be designed in one piece as an angle element.
- the fitting according to the invention particularly preferably has two threaded screws arranged on both sides of the rail, which each reach through a through opening of the second clamping bracket and are screwed into a threaded opening of the first clamping bracket, in particular the carriage, in order to move the two clamping brackets against one another and one in between wall to jam.
- the threaded screws serve as adjusting means for setting the span of the clamping bracket. The span of the clamping angle is reduced by the threaded screws until a sufficient clamping force of the fitting is achieved on the wall.
- the second clamping bracket preferably reaches under the first clamping bracket with at least one base leg, in particular a base leg of the first clamping bracket, and is guided on the first clamping bracket.
- the rail has, at its end facing the second clamping angle, a bracket with an opening standing up at right angles from the rail base, and the second clamping bracket has an upright bracket with an opening: a locking screw can be screwed or screwed into these two openings in order to rotate the two clamping brackets in a desired Determine the shifting position on the rail.
- a guide bush made of plastic, into which the locking screw is captively screwed for the purpose of pre-assembly.
- the rail is fastened to a frame base of the frame at a predetermined distance from a front edge of the frame.
- the first clamping bracket is guided along the rail until it rests against a frame leg of the frame.
- the frame is placed in a wall opening and the first clamping bracket is placed against the wall.
- the second clamping bracket is pushed under the first clamping bracket until it rests against the wall on the opposite side.
- the clamping brackets are clamped to the wall by tightening the threaded screws.
- the second clamping bracket is fixed to the rail and thus the frame to the wall by means of the locking screw.
- the rail and/or the carriage are preferably designed as bent metal sheets.
