Description

Die Erfindung betrifft eine sanitäre Wandarmatur mit einem Gehäuse, an welchem mindestens ein Anschlußstutzen zum Anschluß an die Hausleitung ausgebildet ist, mit einer Abdeckrosette, welche auf dem Anschlußstutzen axial verschraubbar ist, und mit einem Formdichtring, welcher die Abdeckrosette gegen den Anschlußstutzen abdichtet und eines der beiden Gewinde trägt, die bei der Verschraubung der Abdeckrosette zusammenwirken.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.

Bei sanitären Wandarmaturen wird bekanntlich die Anschlußstelle zur Hausleitung, die üblicherweise einen den Anschlußstutzen der Wandarmatur mit dem Hausleitungssystem verbindenden S-Anschluß umfaßt, optisch von einer Abdeckrosette verkleidet. Diese Abdeckrosette sollte einerseits gegenüber dem Anschlußstutzen der Wandarmatur abgedichtet sein, damit hier kein Spritz- oder Putzwasser eindringen kann; andererseits sollte die Abdeckrosette eine gewisse axiale Fixierung in ihrer wandnahen Position aufweisen.In the case of sanitary wall fittings, it is known that the 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, is optically covered by a cover rosette. This 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.

Bei der in der DE-A-38 06 492 beschriebenen bekannten sanitären Wandaramtur der eingangs genannten Art übernimmt beide Funktionen, nämlich diejenige der Abdichtung ebenso wie diejenige der axiale Fixierung, ein Formdichtring, welcher auf den Anschlußstutzen aufgezogen und mit einem Außengewinde versehen ist. Auf dieses Außengewinde wird die Abdeckrosette aufgedreht, die an dem Rand der Öffnung, welche den Anschlußstutzen aufnimmt, mit einem komplementären Gewinde versehen ist. Bei dieser Ausgestaltung ist es möglich, daß in bestimmten Relativpositionen der Abdeckrosette gegenüber dem Anschlußstutzen der das Außengewinde tragende Formdichtring sichtbar wird, was optisch stören kann. Dies gilt insbesondere dann, wenn aufgrund von Unregelmäßigkeiten der Gebäudewand, an welcher die Armatur befestigt werden soll, bzw. der in dieser Wand verlegten Hausleitungen die beiden Abdeckrosetten von Mischarmaturen unterschiedlich nahe an die Wand herangeschraubt werden müssen. In diesem Falle sind die sichtbaren Bereiche der Formdichtringe unterschiedlich breit.In the known sanitary wall fitting of the type mentioned in DE-A-38 06 492, 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. With this configuration, it is possible that in certain relative positions the cover rosette opposite the connection piece of the sealing ring bearing the external thread is visible, which can be visually disturbing. This applies in particular if, due to irregularities in the building wall to which the fitting is to be fastened, or the house lines laid in this wall, the two cover rosettes of mixing fittings must be screwed differently close to the wall. In this case, the visible areas of the molded sealing rings are of different widths.

Aus der DE-C-879 678 ist ferner eine Abdeckrosette bekannt, die einen sich in die Einbauwand hineinstreckenden rohrförmigen Gewindeansatz aufweist. Mit diesem Gewindeansatz wird die Abdeckrosette auf einen Bereich größeren Durchmessers der Hausleitung aufgeschraubt. Die Hausleitung durchragt mit einem Bereich kleineren Durchmessers die Abdeckrosette. Auf diesen Bereich kleineren Durchmessers wird dann die eigentliche Sanitärarmatur aufgeschraubt, wobei zwischen Abdeckrosette und wandseitiger Stirnseite der Sanitärarmatur eine Dichtung verklemmt wird. Diese Befestigungsart setzt eine unübliche Ausgestaltung der Hausleitungsenden voraus.From DE-C-879 678 a cover rosette is also known 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.

Aufgabe der vorliegenden Erfindung ist es, eine sanitäre Wandarmatur der eingangs genannten Art derart auszugestalten, daß der Formdichtring zwar weiterhin sowohl die Funktion der Abdichtung als auch der Gewindeverbindung zwischen Abdeckrosette und Anschlußstutzen dient, daß aber andererseits der Formdichtring in keiner Relativposition der Rosette sichtbar wird.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.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Formdichtring im Inneren der Abdeckrosette befestigt und gemeinsam mit dieser bewegbar ist und aufweist:

  • a) einen ersten Bereich, welcher an dem Anschlußstutzen verschiebbar anliegt und die Abdichtung besorgt;
  • b) einen zweiten, gegenüber dem ersten Bereich axial versetzten Bereich, der gewindeartig mit einem Außengewinde zusammenwirkt, welches sich am wandnahen Ende des Anschlußstutzens befindet.
This object is achieved in that the molded sealing ring is fastened inside the cover rosette and can be moved together with it and has:
  • a) a first area which slidably abuts the connecting piece and provides the seal;
  • b) a second area which is axially offset from the first area and which interacts in a thread-like manner with an external thread which is located at the end of the connecting piece near the wall.

Die der Erfindung gesetzten Zielen werden also mit folgenden Überlegungen erreicht:The objectives set for the invention are therefore achieved with the following considerations:

Zunächst wird der Formdichtring in das Innere der Abdeckrosette verlegt und gemeinsam mit der Abdeckrosette bewegt. Bereits hierdurch wird verhindert, daß der Formdichtring sichtbar werden kann. Zum zweiten wird der Bereich, welcher der Abdichtung gegenüber dem Anschlußstutzen dient, von demjenigen Bereich getrennt, welcher nach Art eines Gewindes mit einem Gewinde am Anschlußstutzen zusammenwirkt. Das Außengewinde am Anschlußstutzen bzw. an einem in der Montagestellung der Wandarmatur gegenüber dem Anschlußstutzen feststehenden und diesem benachbarten Teil sollte nämlich nahe an der Gebäudewand liegen, damit es in allen axialen Relativstellungen der Abdeckrosette von dieser abgedeckt wird.First, 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. Secondly, 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.

Von besonderem Vorteil ist, wenn sich das Außengewinde an dem aus dem Anschlußstutzen herausragenden Bereich eines Anschlußnippels befindet, der gegenüber dem Anschlußstutzen axial feststeht aber verdrehbar ist und der Befestigung eines S-Anschlusses dient. Hierdurch wird ein doppelter Vorteil erzielt: Zum einen läßt sich das Anschlußgewinde auf den Anschlußnippel einfacher aufbringen als auf den Anschlußstutzen der Wandarmatur; zum anderen liegt der fragliche Bereich des Anschlußnippels noch näher an der Gebäudewand als das Ende des Anschlußstutzens selbst.It is particularly advantageous if the external 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. This achieves a double advantage: On the one hand, the connection thread can be applied more easily to the connection nipple than to the connection piece of the wall fitting; on the other hand, the area of the connection nipple in question is even closer to the building wall than the end of the connection piece itself.

Dabei wird bevorzugt, daß das Außengewinde auf die ggfs. abgerundeten Kanten einer Schlüsselfläche des Anschlußnippels aufgeschnitten ist. Die Schlüsselfläche dient dazu, den Anschlußnippel gegenüber dem Anschlußstutzen mittels eines Gabelschlüssels oder dergleichen zu verdrehen, wenn die Verbindung mit dem S-Anschluß erfolgen soll.It is preferred that the external thread 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.

Im allgemeinen genügt es, wenn der zweite Bereich des Formdichtringes eine glatte zylindrische Innenmantelfläche aufweist, welche sich beim Aufdrehen in das Außengewinde eindrückt. Hierdurch wird die Herstellung des Formdichtringes erleichtert.In general, it is sufficient if 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.

Der Formdichtring kann zusätzlich einen dritten Bereich aufweisen, der den Rand der Abdeckrosette gegen die Gebäudewand abzudichten in der Lage ist. Dieser dritte Bereich würde also axial etwas gegenüber dem Rand der Abdeckrosette vorstehen und sich elastisch gegen die Gebäudewand anlegen, wenn die Abdeckrosette durch Verschrauben auf dem Anschlußstutzen in ihre Endlage gebracht wird.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.

Die Befestigung des Formdichtringes an der Abdeckrosette geschieht vorteilhafterweise so, daß der Formdichtring auf einen Kragen der Abdeckrosette aufgeknüpft ist, welcher entlang des Randes der Öffnung verläuft, die den Anschlußstutzen umgreift. So ist der Formdichtring zuverlässig an der Abdeckrosette befestigt und macht alle deren Bewegungen mit.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.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; es zeigen

Figur 1:

Figur 2:
in etwas vergrößertem Maßstab die Abdeckrosette der in Figur 1 gezeigten Wandarmatur.
An embodiment of the invention is explained below with reference to the drawing; show it
Figure 1:
schematically the top view of a sanitary wall fitting, broken open in the area of a connecting piece;
Figure 2:
in a somewhat enlarged scale the cover rosette of the wall fitting shown in Figure 1.

In Figur 1 ist eine sanitäre Wandarmatur, die nur teilweise gezeigt ist, mit dem Bezugszeichen 1 gekennzeichnet. Deren genauer Aufbau ist im vorliegenden Zusammenhang ohne Interesse. Es genügt zu wissen, daß in dem Gehäuse 2 der sanitären Wandarmatur 1 verschiedene Sanitärelemente, insbesondere Absperr- und/oder Mischventile, vorgesehen sind. Im allgemeinen weist das Gehäuse 2 Anschlußstutzen 3 auf, von denen in Figur 1 einer dargestellt ist und die zur wassermäßigen Verbindung des Gehäuses 2 mit den Warm- und Kaltwasserleitungen des Hausleitungssystemes dienen. In dem Anschlußstutzen 3 ist ein drehbarer Anschlußnippel 4 untergebracht, der jedoch axial feststeht. Er weist an seinem über das Gehäuse 2 hinausragenden Bereich in bekannter Weise eine Schlüsselfläche 6 auf (in der Zeichnung nicht direkt sichtbar, da unter einem Winkel von 60° zu Zeichenebene stehend bzw. parallel zu dieser versetzt), in dessen abgerundete Kanten ein Gewinde 7 eingeschnitten ist. An der Innenmantelfläche innerhalb des Gehäuses 2 trägt der Anschlußnippel 4 ein Innengewinde 5. Dieses wirkt in bekannter Weise mit dem Außengewinde eines S-Anschlusses zusammen, der die Verbindung zwischen dem Gehäuse 2 der Armatur und dem Hausleitungssystem herstellt. Durch Verdrehen des Anschlußnippels 4 wird dessen Innengewinde 5 auf den S-Anschluß aufgeschraubt und dadurch die gesamte Wandarmatur 1 in Richtung auf die Wand, an welcher sie installiert werden soll, gezogen. Zwischen den Stirnseiten des S-Anschlusses und des Schraubteils 8 ist üblicherweise eine Flachdichtung angeordnet.In Figure 1, 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. In general, 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. In the connection piece 3, a rotatable connection nipple 4 is accommodated, but which is axially fixed. It has a wrench surface 6 on its area protruding beyond the housing 2 (not directly visible in the drawing, since it is at an angle of 60 ° to the plane of the drawing or offset parallel to it), a thread 7 in the rounded edges thereof is incised. 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.

Die axiale Fixierung bei gleichzeitiger Verdrehbarkeit des Anschlußnippels 4 wird durch ein Schraubteil 8 gewährleistet, welche in eine zum Anschlußstutzen 3 des Gehäuses 2 koaxiale Gewindebohrung 9 eingedreht ist. Beim Einschrauben wird von einer Mehrkantfläche 10 Gebrauch gemacht, die im oberen Bereich der inneren Durchgangsbohrung 11 des Schraubteils 8 vorgesehen ist und an welcher ein geeignetes Werkzeug ansetzen kann.The axial fixation with simultaneous rotatability of the connecting nipple 4 is ensured by a screw part 8 which is screwed into a threaded bore 9 coaxial with the connecting piece 3 of the housing 2. When screwing in, use is made of 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.

Ist die sanitäre Wandarmatur über den S-Anschluß mit dem Hausleitungssystem verbunden, so kann von dort das Wasser über den S-Anschluß und die Innenbohrung 11 des Schraubteiles 8 zu einem Wasserraum 12 innerhalb des Gehäuses 2 fließen. Im Wasserraum 12 befindet sich ein zylindrisches Schmutzfangsieb 13. Dieses wird von einem Halter 14 getragen, der von der Seite her in das Gehäuse 2 der sanitären Wandarmatur eingeschraubt ist. Das in den Wasserraum 12 gelangende Wasser durchsetzt das zylindrische Schmutzfangsieb 13 radial von außen nach innen und strömt dann in axialer Richtung in Figur 1 nach links, so daß es in einen weiteren Wasserraum 15 gelangen kann. Der weitere Weg des Wassers ist im vorliegenden Zusammenhang ohne Bedeutung.If 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. In the water space 12 there is 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.

Zur optisch gefälligen Verkleidung der Anschlußstelle der sanitären Wandarmatur 1 an das Hausleitungssystem im Bereich des Anschlußnippels 4 und des hiermit verbundenen S-Anschlusses ist eine Abdeckrosette 16 vorgesehen. Bei dieser handelt es sich um ein schalenförmiges Gebilde, welches im Boden eine Öffnung 17 aufweist, die über den Anschlußstutzen 3 des Gehäuses 2 geschoben ist. Vom Rand der Öffnung 17 erstreckt sich ein umgebogener, sich geringfügig konisch erweiternder Kragen 18 ins Innere der von der Abdeckrosette 16 gebildeten Schale.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.

Auf den Kragen 18 der Abdeckrosette 16 ist ein Formdichtring 19 aus elastischen, dichtenden Material, insbesondere einem Gummi geeigneter Härte, aufgeknüpft. Der Formdichtring 19 besitzt eine erste, radial nach innen stehende Dichtlippe 20, die an der inneren Stirnseite des Kragens 18 der Abdeckrosette 16 anliegt und diese gegen den Anschlußstutzen 3 des Gehäuses 2 eine abdichtet.A molded sealing ring 19 made of elastic, sealing material, in particular a rubber of suitable hardness, is knotted onto the collar 18 of 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.

Axial gegenüber der Dichtlippe 20 versetzt ist an den Formdichtring 19 ein radial nach innen springender Flansch 21 angeformt, der über eine gewisse axiale Erstreckung hinweg eine zylindrische Innenmantelfläche 22 besitzt.Axially offset from the sealing lip 20, 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.

Der Sinn und die Funktionsweise der oben beschriebenen Konstruktionsmerkmale sind folgende:The meaning and functionality of the design features described above are as follows:

Vor dem Anschließen der sanitären Wandarmatur 1 an das Hausleitungssystem bzw. den hiermit verbundenen S-Anschluß befindet sich die Abdeckrosette 16 mit dem eingeknüpften Formdichtring 19 in der in Figur 1 dargestellten Position, also vollständig über den Anschlußstutzen 3 geschoben; die Schlüsselfläche 6 des Anschlußnippels 4 liegt frei. Die Wandarmatur 1 kann nunmehr in bekannter Weise mit dem S-Anschluß verschraubt werden, indem mit einem geeigneten Werkzeug der Anschlußnippel 4 verdreht und dabei auf das entsprechende Gewinde des S-Anschlusses geschraubt wird. Ist letzterer dicht mit der Wandarmatur 1 verbunden, wird die Abdeckrosette 16 mit dem Formdichtring 19 nach hinten, auf die Wand zu, geschoben, bis die zylindrische Innenmantelfläche 22 des Formdichtringes 19 in Anlage an das Außengewinde 7 kommt, welches sich auf den Kanten der Schlüsselfläche 6 des Anschlußnippels 4 befindet. Ab nun wird die Abdeckrosette 16 gemeinsam mit dem Formdichtring 19 verdreht und zwar in einem solchen Sinne, daß sich die zylindrische Innenmantelfläche 22 des Formdichtringes 19, sich in das Außengewinde 7 des Anschlußnippels 4 drükkend, auf letzterem aufschraubt, bis der Rand der Abdeckrosette 16 an der Wand anliegt, an welcher die sanitäre Wandarmatur 1 angebracht worden ist.Before connecting the sanitary wall fitting 1 to the house management system or the S connection connected to it there is the cover rosette 16 with the molded-in sealing ring 19 in the position shown in FIG. 1, that is to say completely pushed over the connecting piece 3; the key surface 6 of the connecting nipple 4 is exposed. The wall fitting 1 can now be screwed to the S connection in a known manner by rotating the connecting nipple 4 with a suitable tool and screwing it onto the corresponding thread of the S connection. If the latter is tightly connected to the wall fitting 1, 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. From now on, 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.

Die Abdeckrosette 16 ist auf diese Weise fest in Position gebracht und gleichzeitig gegen das Eindringen von Schmutz- und Spritzwasser von der wandfernen Seite her geschützt.In this way, 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.

Ggf. kann der Spalt zwischen dem Rand der Abdeckrosette 16 und der Gebäudewand durch eine zusätzliche Dichtung verschlossen werden, die auch einstückig mit dem Formdichtring 19 gestaltet sein kann. Im letzteren Falle kann sich an den Formdichtring 19 ein glockenförmiger Bereich anschließen, der die Innenwandung der Abdeckrosette 16 auskleidet und mit einer Dichtlippe geringfügig über deren Rand übersteht.Possibly. 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. In the latter case, 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.
