Definitions

  • the invention relates to a sanitary wall fitting with a housing on which at least one connection piece is designed for connection to the house line, with a cover rosette which can be axially screwed onto the connection piece, and with a molded sealing ring which seals the cover rose against the connection piece and one of the carries both threads that work together when screwing the cover rosette.
  • connection point to the house line which usually comprises an S connection connecting the connection piece of the wall valve to the house line system
  • cover rosette should be sealed on the one hand against the connecting piece of the wall fitting so that no splash or cleaning water can penetrate here; on the other hand, the cover rosette should have a certain axial fixation in its position close to the wall.
  • both functions namely that of sealing as well as that of axial fixation, assume a form sealing ring which is fitted onto the connecting piece and provided with an external thread.
  • the cover rosette is screwed onto this external thread and is provided with a complementary thread at the edge of the opening which receives the connecting piece.
  • a cover rosette which has a tubular threaded extension extending into the installation wall. With this thread approach, the cover rosette is screwed onto an area of larger diameter of the house line. The house management extends through an area with a smaller diameter through the cover rosette. The actual sanitary fitting is then screwed onto this area of smaller diameter, a gasket being jammed between the cover rosette and the wall-side end face of the sanitary fitting.
  • This type of fastening requires an unusual design of the ends of the house management.
  • the object of the present invention is to design a sanitary wall fitting of the type mentioned in such a way that the molded sealing ring continues to serve both the function of the seal and the threaded connection between the cover rosette and the connecting piece, but on the other hand the molded sealing ring is not visible in any relative position of the rosette.
  • the molded sealing ring is placed inside the cover rosette and moved together with the cover rosette. This already prevents the molded sealing ring from becoming visible.
  • the area which is used to seal off the connecting piece is from the area separated, which cooperates in the manner of a thread with a thread on the connecting piece.
  • the external thread on the connecting piece or on a part which is fixed in the mounting position of the wall fitting relative to the connecting piece and this adjacent part should be close to the building wall, so that it is covered by the cover rosette in all axial relative positions thereof.
  • connection thread is located on the area of a connecting nipple protruding from the connecting piece, which is axially fixed with respect to the connecting piece but can be rotated and is used to fasten an S-connection.
  • connection nipple is cut on the possibly rounded edges of a wrench surface of the connection nipple.
  • the key surface serves to turn the connection nipple with respect to the connection piece by means of a fork wrench or the like if the connection to the S connection is to be made.
  • the second area of the molded sealing ring has a smooth cylindrical inner surface, which is pressed into the external thread when it is unscrewed. This simplifies the manufacture of the molded sealing ring.
  • the molded sealing ring can additionally have a third area, which is the edge of the cover rosette against the building wall is able to seal. This third area would protrude axially somewhat from the edge of the cover rosette and resiliently rest against the building wall when the cover rosette is brought into its end position by screwing on the connecting piece.
  • the attachment of the molded sealing ring to the cover rosette advantageously takes place in such a way that the molded sealing ring is tied onto a collar of the cover rosette which runs along the edge of the opening which surrounds the connecting piece.
  • the molded sealing ring is reliably attached to the cover rosette and follows all of its movements.
  • a sanitary wall fitting which is only partially shown, is identified by the reference number 1.
  • Their exact structure is of no interest in the present context. It is sufficient to know that various sanitary elements, in particular shut-off and / or mixing valves, are provided in the housing 2 of the sanitary wall fitting 1.
  • the housing 2 has connecting pieces 3, one of which is shown in FIG. 1 and which are used for the water-based connection of the housing 2 to the hot and cold water pipes of the house pipe system.
  • a rotatable connection nipple 4 is accommodated, but which is axially fixed.
  • connection nipple 4 On the inner circumferential surface within the housing 2, the connection nipple 4 carries an internal thread 5. This interacts in a known manner with the external thread of an S-connection, which establishes the connection between the housing 2 of the fitting and the house management system. By turning the connection nipple 4, its internal thread 5 is screwed onto the S-connection, thereby pulling the entire wall fitting 1 in the direction of the wall on which it is to be installed.
  • a flat gasket is usually arranged between the end faces of the S connection and the screw part 8.
  • a screw part 8 which is screwed into a threaded bore 9 coaxial with the connecting piece 3 of the housing 2.
  • a polygonal surface 10 which is provided in the upper region of the inner through bore 11 of the screw part 8 and on which a suitable tool can be attached.
  • the sanitary wall fitting is connected to the house pipe system via the S connection, then the water can flow from there via the S connection and the inner bore 11 of the screw part 8 to a water space 12 within the housing 2.
  • a cylindrical strainer 13 This is carried by a holder 14 which is screwed into the housing 2 of the sanitary wall fitting from the side. That in the water room 12 incoming water passes through the cylindrical dirt strainer 13 radially from the outside inwards and then flows in the axial direction to the left in FIG. 1, so that it can reach a further water space 15.
  • the further path of water is irrelevant in the present context.
  • a cover rosette 16 is provided for visually pleasing cladding of the connection point of the sanitary wall fitting 1 to the house line system in the area of the connection nipple 4 and the S-connection connected to it.
  • This is a bowl-shaped structure which has an opening 17 in the bottom which is pushed over the connecting piece 3 of the housing 2.
  • a bent, slightly conically widening collar 18 extends from the edge of the opening 17 into the interior of the shell formed by the cover rosette 16.
  • the molded sealing ring 19 has a first, radially inward sealing lip 20 which bears against the inner end face of the collar 18 of the cover rosette 16 and seals this against the connecting piece 3 of the housing 2.
  • a radially inwardly projecting flange 21 is formed on the molded sealing ring 19 and has a cylindrical inner circumferential surface 22 over a certain axial extent.
  • the cover rosette 16 with the molded sealing ring 19 is pushed backwards towards the wall until the cylindrical inner surface 22 of the molded sealing ring 19 comes into contact with the external thread 7, which is located on the edges of the key surface 6 of the connecting nipple 4 is located.
  • the cover rosette 16 is rotated together with the form sealing ring 19, specifically in such a way that the cylindrical inner circumferential surface 22 of the form sealing ring 19, pressing into the external thread 7 of the connecting nipple 4, is screwed onto the latter until the edge of the covering rosette 16 is on abuts the wall on which the sanitary wall fitting 1 has been attached.
  • the cover rosette 16 is firmly positioned and at the same time protected against the ingress of dirty water and splash water from the side remote from the wall.
  • the gap between the edge of the cover rosette 16 and the building wall can be closed by an additional seal, which can also be designed in one piece with the molded sealing ring 19.
  • a bell-shaped area can adjoin the molded sealing ring 19, which lines the inner wall of the cover rosette 16 and protrudes slightly beyond its edge with a sealing lip.
