Abstract

The invention relates to a component for fastening a profile washer to a edge strip of a sheet which is surrounded by a groove in the profile washer. When assembled, a resilient metal clamp (1) surrounds with two legs (2,3) the edge strip. An intermediate layer (6,26) of a lower level of hardness is provided between the metal bracket (1) and the edge strip. The distance between the legs (2,3) lessens in the end regions (4,5) thereof, and widens again at the ends thereof.

Claims

1. In an element for fixing a profiled seal to the edge strip of a metal sheet, which edge strip is embraced by a groove in the profiled seal, the improvement wherein two limbs of a resilient metal clip, which is constructed for embedding in the profiled seal, embrace a U-shaped plastic part, which is constructed in such a way that it surrounds the edge strip when the profiled seal is fixed and serves as an intermediate layer between the metal clip and the edge strip, wherein the spacing between the limbs narrows in end regions of the limbs and widens again at the ends of the limbs, and wherein the U-shaped plastic part has a shape which is matched to the narrowed regions between the limbs and has a lower hardness than the metal clips.

2. A fixing element according to claim 1, wherein outside the narrowed regions of the limbs the plastic part is narrower than the spacing between the limbs.

3. A fixing element according to claim 2, wherein outside the narrowed regions the limbs of the metal clip each comprise at least one inwardly oriented embossed formation for centering the plastic part.

4. A fixing element according to claim 2, wherein the plastic part has a greater width following the narrowed regions than outside the narrowed regions.

5. A fixing element according to claim 2, wherein the plastics part has at least one projection which fits into an opening in the metal clip.

6. A fixing element according to claim 5, wherein the projection is a rib which extends transversely to the direction of the sheet metal edge and which fits into an open slot at the end of the limb.

7. A fixing element according to claim 2, wherein the plastic part is trapezoidal, wherein the shorter side runs at the sheet metal edge and the longer side is situated outside the ends of the limbs of the metal clip.

8. A fixing element according to claim 1, wherein the U-shaped plastic part has opposing, inner planar surfaces which contact the edge strip.
