INSTALLATION DEVICE - MONTERINGSANORDNING

The present invention relates to a mounting cover which is used as a mounting response when mounting parts extending through an opening in a thin surface material which, due to its thinness, lacks surface pressure resistance and sufficient strength to receive and secure parts mounting members, the mounting cover being 10 having an inner diameter substantially the same as the diameter of the opening in the surface material, wherein the annular plate has a slot that allows the plate to rotate through the opening.

The invention in question has applications in many fields, such as construction, shipbuilding, automotive, mechanical engineering, etc. New and often better and cheaper materials for their main purpose are constantly emerging in today's industrialized world. Thus, for certain sealing-20 purposes, increasingly thinner constructions have emerged. When penetrations have to be made in these products, which are often particularly unsuitable as nail, screw or rivet bases, both fastening and sealing problems often arise. Various known mounting arrangements are shown in 25 mm. SE Publication No. 441,208 and U.S. Patents 2,244,976 and 4,570,943.

The object of the present invention has thus been to be able, in the best technical and economical way, to be able to take advantage of the good properties of new, thin and inexpensive sealing materials also with minimal additional work. The latter because, thanks to the invention, the entire installation work can be carried out in one and the same workstation, entirely on one side of the sealing layer.

The invention is characterized in that the flat, annular plate is provided at its outer circumference with a circumferential flange at a substantially right angle thereto, the gap extending radially through the flat, annular plate and at its edge through the flange at an angle to the flat plate.

The advantages consist, on the one hand, that one simple detail can replace the previously necessary, often bulky, complicated, expensive variable / stiffening material, and, on the other hand, the mini-10 of the working time required at the penetration point. In addition, an ergonomically better situation is achieved than before.

The implementation, installation and use of the invention will become apparent from the following description with reference to the accompanying drawings.

Figure A shows a perspective view of an embodiment of a mounting cover according to the invention. The dominant plane of the mounting cover and the annular surface 1 have a rectangularly folded and rigid edge 2 along its entire outer circumference Dy 2. The inner surface d ^ of the planar and annular surface has two different outwardly projecting tongues in its own plane: narrower and thus flexible bending tongue The dominant plane and the annular surface are provided with a plurality of fastening devices 6, for example with holes for sheet metal screws. Finally, the entire annular structure is cut off by a radial section 7 common to all surfaces, made at an angle α to the planar annular surface.

Fig. B shows a perspective view of a mounting cover prepared for mounting in a hole 8C made in a thin plate-like material 9C. The preparation takes place by lifting one part 10 of the annular mounting cover 10 on one side of the section 7 relative to the other part 11. This provides an opening 12 which allows the entire mounting cover to be guided in and "screwed" into the hole.

Figure C shows how the mounting cover is placed in a hole made in a thin, plate-like material. The positioning and correct position of the mounting cover is detected so that the guide edge 3 falls into the hole. By bending the bending tongues 5 ^, 5 52, the mounting cover is also attached to the plate-like material.

In this position, it is now possible to pass a specially adapted detail through the central hole 10 13 of the mounting cover into a thin sealing layer. The profile and position of the guide tongues 4 in this case require coordination with the groove of the corresponding bushing detail. By matching the position between the guide tongues 4 of the mounting cover 4 and the fastening devices 6 and the position 15 between the grooves and fastening elements of the bushing part, the fastening elements are guided directly towards the corresponding fastening devices covered by the sealing layer but equally on the other side. The interconnection and the possible sealing task can then take place between the thin plate-like material and the associated lead-through part, using the mounting cover as an aid.
