Definitions

• the present invention relates to a built-in mounting system for a sanitary device comprising a mounting frame for a sanitary device, which mounting frame is to be placed on a floor in front of a rear wall.
• the sanitary device can be for example a toilet, a bidet, a urinal or a washbowl.
• Such built-in mounting systems for mounting toilets are known and available on the market.
• CH 694 487 an example of such a built-in mounting system for a toilet is disclosed.
• the known mounting frame is made of profiled section elements and is attached to the floor and/or to the rear wall.
• a built-in cistern is secured to a mounting frame.
• a toilet bowl can be secured to the frame as well.
• front wall in front of the mounting frame to hide the mounting frame and to provide surface for a finishing layer like tiles, paint, plaster or otherwise.
• the built-in mounting system is thus positioned between the front wall and the rear wall, the latter usually being an already existing wall of a room.
• the front wall is commonly made of plasterboard or a wooden board that is often screwed to the mounting frame. It is also known to build a front wall of bricks or cellular concrete blocks or other suitable builiding material. Typically some cutouts are provided in the front wall to lead through a flushing pipe extending between the cistern and the toilet bowl, a discharge pipe for chanellling away flushing water from the toilet bowl and threaded rods or the like for mounting the toilet bowl.
• an opening for an actuating button or plate for operating the flushing mechanism and for providing access to the cistern in case of technical malfunction is ususally provided in the front plate.
• the front surface can be finished by tiling, plastering, painting or otherwise after which the toilet bowl can be mounted.
• the covering boards like plaster boards or the wooden boards to be placed in front of the mounting frame are heavy and it is time consuming to saw them down to size. Moreover the sawing of the boards creates dust that spoils the environment. Furthermore screwing the boards to the frame is labour-intensive and takes a lot of time. It is the sort of work which is generally not carried out by a plumber or installer. Therefore most plumbers/installers leave this kind of work to a contractor after which the plumber/installer returns to finish the work by, if necessary tiling the front wall, and installing the toilet bowl, which consequently introduces an additional logistic and working complication.
