Description

The The invention relates to an installation system for front wall mounting, in particular for sanitary rooms, with Section bars at least one decorative trim panel and fasteners for releasable Fixing the cladding plate to at least one of the profile bars.

Usually Both toilet bowls, bidets, urinals and sinks are on wall installations assembled. Known pre-wall installations consist of prefabricated Carrying frames or supporting frames produced on the construction site, why profile bars Tailored at the construction site and with each other by screw or Rivet connections are connected. The support frame is then with Support plates, usually clad with plasterboard and then tiled. Attaching the carrier plates as well as the sticking and grouting of the tiles are very time consuming Work. These works usually become on the one hand by sanitary installers or drywall and on the other by tiler. Accordingly is a temporal coordination of different trades required which also means a workload.

Very difficult to make necessary in verfliesten pretext installations Repair work on integrated cisterns, water supply lines and drainpipes. In general, require such repair work with noise and dirt related caulking, in which case for the destroyed tiles Often no suitable replacement is available.

As an alternative to conventional cladding of sanitary wall installations by means of plasterboard and tiles have already been proposed cladding panels made of plastic, which have their intended for permanent use outer decorative surface already in the delivery state and are provided on its back with hooks for releasable connection with attached to the support pin ( DE 100 01 517 C1 ). The hooks screwed to the trim panel have a hook mouth extending obliquely upward from the mouth opening and toward the front of the trim panel (decorative panel). The pins associated with the hooks are attached to vertical metal profiles of the support frame and protrude laterally.

A similar installation system for wall mounting in the sanitary area is from the DE 296 03 836 U1 known. In the known system of mounting rails, which are attached to a wall and the floor, at least one mounting frame and spacers formed a support frame. In the support frame, a functionally independent furniture element is arranged adjacent to the mounting frame, wherein the mounting frame is covered with a surface-coated decorative plate, which structurally forms a front with the visible surface of the furniture element. The decorative plate is interchangeable frame in the mounting suspended. For this purpose, hook plates are screwed to the back of the decorative panel, which are mounted on wedge plates, which are screwed to the vertical uprights of the mounting frame.

The from the DE 100 01 517 C1 and the DE 296 03 836 U1 Although known installation systems allow, if necessary, a simple, non-destructive removal of the decorative panels and thus good access to the sanitary units and pipelines mounted in the support frame, the hooked attachment (suspension) of decorative panels is sometimes unsatisfactory, because this type of attachment requires a high level craftsmanship in the alignment of the hook and pin or wedge plates to each other to achieve a perfect, especially rattle-free fit of the decorative plate on the support frame.

Of the present invention is based on the object, an installation system of the type mentioned above with regard to the attachment of the decorative To improve cladding panels on the profile bars of the support frame.
