Most components of modern building technology, especially pipelines, are designed to be invisible in buildings. To do this, they are installed in walls or shafts. Nevertheless, it is necessary to provide control elements for the operation of the building services. With these, too, it is preferred that only the part of these control elements that is necessary for operation is visible. The other part that has the actual function is provided "under plaster" just like other components of the building services. For this purpose, it is often necessary to provide holes in walls that accommodate these controls and other building services components. A number of commercial trim systems, typically using cover rosettes as lids, are known in the prior art. When operating or maintaining the controls, there is frequent contact between the operator and the cover of the trim system. This contact causes annoying rattling noises, especially if the wall surface is covered with grouted tiles.

In the DE 102 19 471 A1 describes a cladding system that uses a positive connection between a geometry of a support plate and a geometry of a cover.

the DE 10 2015 009 105 A1 finally shows another type of connection between a cover and a carrier plate, with an elastic securing band being used from the outside in order to stabilize a form-fitting connection.

The present invention is generally based on the object of contributing to the elimination of one or more disadvantages resulting from the prior art. In particular, an object of the invention is to provide cladding systems with a lower noise development during operation, which are also well suited for installation and maintenance of the control elements without the need for a special use of tools.

Here it is preferred that the lip touches the wall in the case of the built-in trim system. In addition, it is preferred that the lid touches the lip in the case of the built-in trim system.

The lip is preferably designed to avoid direct contact between the lid and the wall in the case of the built-in distribution system. Preferably, the lip is substantially triangular, with the base of the triangle forming part of the attachment geometry and the two legs of this triangle touching the wall and cover in the case of the built-in distribution system. The lip preferably runs around at least 50%, preferably at least 70% and particularly preferably at least 90% of the circumference of the fastening geometry. In this way it can be achieved that the lip avoids direct contact between the wall and the ceiling in as many areas as possible between the cover and the wall in the case of the built-in cladding system.

In an embodiment 3, the cladding system is designed according to embodiment 1 or 2, with the elastic attachment geometry having a snap-in geometry designed and configured for snapping into the first attachment geometry. The snap geometry is preferably designed as a bead. This bead is preferably located farther from the wall in the case of the built-in cladding system compared to the lip. Furthermore, it is preferred that when the cover is placed on the carrier plate, part of the snap geometry, in particular the bead, is pressed in and, when the cover is moved further towards the wall, relaxed.

According to the invention, the elastic fastening geometry is formed from an elastomer. If the elastic attachment geometry is part of a seal, this is preferably also formed from an elastomer. Particularly suitable elastomers are those that allow reversible indentation by manual force. In this way, the cover can be placed and connected in a form-fitting manner on the snap-on geometry of the elastic fastening geometry without the use of special tools.
