  1. a) a valve body;
  2. b) a trained in this receiving space for a control cartridge;
  3. c) a usable in the receiving space control cartridge, which has a connection device for at least two water pipes, wherein the connection means has water passage openings for the water pipes, which are connected to corresponding water-bearing areas in the control cartridge.

Bei marktbekannten Sanitärarmaturen bildet eine Messingplatte den Boden der Steuerkartusche. Die Messingplatte weist Wasserdurchtrittsöffnungen zu den wasserführenden Bereichen der Steuerkartusche auf. Die Wasserleitungen sind in die Wasserdurchtrittsöffnungen eingesteckt, eingeschraubt oder an die Messingplatte angelötet.In well-known sanitary fittings a brass plate forms the bottom of the control cartridge. The brass plate has water passage openings to the water-bearing areas of the control cartridge. The water pipes are plugged into the water passage openings, screwed or soldered to the brass plate.

Bei anderen marktbekannten Sanitärarmaturen sind die Wasserleitungen in die Wasserdurchtrittsöffnungen eingesteckt und werden von außen mit einem Steckteil umgriffen und gegenüber der Steuerkartusche fixiert. Das Steckteil wird hierzu in radialer Richtung um die Wasserleitungen gesteckt und umgreift diese jeweils mit einer Klaue. Zur Führung der Wasserleitungen ist zwischen den beiden Wasserleitungen ein Führungssteg angeordnet.In other well-known sanitary fittings, the water pipes are inserted into the water passage openings and are gripped from the outside with a male part and fixed relative to the control cartridge. For this purpose, the plug-in part is inserted in the radial direction around the water pipes and encompasses these in each case with a claw.

Aufgabe der vorliegenden Erfindung ist es, eine Sanitärarmatur der eingangs genannten Art so auszugestalten, dass zwei Wasserleitungen möglichst einfach mit der Steuerkartusche verbunden werden können.Object of the present invention is to provide a sanitary fitting of the type mentioned in such a way that two water pipes can be easily connected to the control cartridge.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass

  • d) die Wasserleitungen in jeweilige Leitungsaufnahmen der Anschlusseinrichtung eingesteckt sind und ein Klemmelement zwischen den dort im Wesentlichen parallelen Wasserleitungen angeordnet ist und in jeweilige Nuten in den Wasserleitungen eingreift;
  • e) das Klemmelement so in einer Klemmenaufnahme der Anschlusseinrichtung fixiert ist, dass es die Wasserleitungen in den Leitungsaufnahmen hält.
This object is achieved in that
  • d) the water pipes are inserted into respective line receptacles of the connection device and a clamping element is arranged between the water lines substantially parallel there and engages in respective grooves in the water lines;
  • e) the clamping element is fixed in a terminal receptacle of the connection device so that it holds the water pipes in the cable receptacles.

Erfindungsgemäß ist also ein einziges Klemmelement vorgesehen, mit welchem gleichzeitig zwei Wasserleitungen in ihren jeweiligen Leitungsaufnahmen fixiert werden können. Da das Klemmelement platzsparend von innen gleichzeitig gegen beide Wasserleitungen presst, erfüllt es zusätzlich die Funktion einer Führung zwischen den Wasserleitungen. Ein separater Führungssteg ist so nicht erforderlich. Um die Verbindung zu lösen, kann das Klemmelement einfach heraus gezogen werden.Thus, according to the invention, a single clamping element is provided, with which two water pipes can be fixed in their respective pipe receptacles at the same time. Since the clamping element presses space-saving from the inside at the same time against both water pipes, it also fulfills the function of a guide between the water pipes. A separate guide bar is not required. To release the connection, the clamping element can be easily pulled out.

Bei einer vorteilhaften Ausführungsform kann das Klemmelement ein Federklemmelement sein. Ein Federklemmelement ist elastisch und kann einfach zwischen die Wasserleitungen eingeschoben werden. In eingeschobenem Zustand drückt das Federklemmelement aufgrund seiner Spannkraft in die Nuten der Wasserleitungen und fixiert so die Wasserleitungen.In an advantageous embodiment, the clamping element may be a spring clamping element. A spring clamping element is elastic and can be easily inserted between the water pipes. In the inserted state presses the spring clamp element due to its Clamping force in the grooves of the water pipes and thus fixes the water pipes.

Zweckmäßigerweise können die Leitungsaufnahmen in einem Einsatz, insbesondere einem Kunststoffeinsatz, angeordnet sein. Auf diese Weise können die Leitungsaufnahmen modular für unterschiedliche Sanitärarmaturen werksseitig vorbereitet werden. Kunststoffeinsätze haben darüber hinaus den Vorteil, dass sie einfach hergestellt werden können und leicht zu montieren sind.Conveniently, the line receptacles can be arranged in an insert, in particular a plastic insert. In this way, the line receptacles can be prepared in the factory for different sanitary fittings. Plastic inserts also have the advantage that they can be easily manufactured and are easy to assemble.

Um zu verhindern, dass der Einsatz bei einem Zug an den Wasserleitungen von dem Armaturengehäuse getrennt wird, kann vorteilhafterweise der Einsatz von der den Wasserleitungen abgewandten Seite her in dem Aufnahmeraum eingebracht sein, und eine Durchrutschsicherung kann für den Einsatz vorgesehen sein.In order to prevent the insert from being separated from the fitting housing during a pull on the water pipes, the insert can advantageously be introduced from the side facing away from the water pipes into the receiving space, and a slip-through protection can be provided for use.

Zweckmäßigerweise kann ein gehäusefester Auflagekragen vorgesehen sein und der Einsatz kann eine zum Auflagekragen komplementäre Auflagestufe aufweisen, mit welcher der Einsatz von der den Wasserleitungen abgewandten Seite an dem Auflagekragen anliegt.Appropriately, a housing-fixed support collar may be provided and the insert may have a support collar complementary support step, with which the use of the water pipes facing away from the support collar.

Nach unten ist der Aufnahmeraum 14 durch einen aus Kunststoff gefertigten Bodeneinsatz 80 begrenzt, auf den oben der untere Bereich der Steuerkartusche 18 aufgesteckt ist. Von der unteren zur oberen Stirnfläche des Bodeneinsatzes 80 erstrecken sich zwei Durchgangsbohrungen 81, von denen in Figur 1 nur eine erkennbar ist. Die Mündungen der Durchgangsbohrungen 81 in die obere Stirnfläche des Bodeneinsatzes 80 kommunizieren mit zwei Zulauföffnungen für Kalt- und Warmwasser in der unteren Stirnseite der Steuerkartusche 18. Eine Auslauföffnung für Mischwasser, die sich ebenfalls in der unteren Stirnseite der Steuerkartusche 18 befindet, kommuniziert mit einem Kanal 82, der in nicht gezeigter Weise zum Wasserauslauf 46 der Einhebelmischarmatur 10 führt.The receiving space 14 is on its side facing the mixing lever, in FIG. 1 above, with a hemispherical spherical cap 20 completed. In the top of the ball cap 20 is one in the FIG. 1 invisible hood opening arranged. Down the receiving space 14 is limited by a bottom insert 80 made of plastic, on the top of the lower portion of the control cartridge 18 is attached. From the lower to the upper end surface of the bottom insert 80, two through holes 81 extend, of which in FIG. 1 only one is recognizable. The mouths of the through holes 81 in the upper end face of the bottom insert 80 communicate with two inlet openings for cold and hot water in the lower end of the control cartridge 18. An outlet opening for mixed water, which is also located in the lower end of the control cartridge 18 communicates with a channel 82, which leads in a manner not shown to the water outlet 46 of the Einhebelmischarmatur 10.

Der Mischhebel ist in bekannte Weise mit einem Stellschaft 28 der Steuerkartusche 18 verbunden.The mixing lever is connected in a known manner with a society 28 of the control cartridge 18.

Durch Schwenken beziehungsweise Drehen des Mischhebels wird der Wasserfluss beziehungsweise die Wassertemperatur in bekannter Weise verändert.By pivoting or rotating the mixing lever, the water flow or the water temperature is changed in a known manner.

Auf der dem Mischhebel abgewandten Seite des Aufnahmeraums 14 schließt sich an diesen ein Anschlussraum 34 an, der an seiner Unterseite offen ist. Der dortige untere Rand des Armaturengehäuses 16 liegt in bekannter Weise an einem nicht gezeigten Waschtisch an.On the side facing away from the mixing lever of the receiving space 14 is followed by a connection space 34, which is open at its bottom. The local lower edge of the fitting housing 16 is in a known manner to a washstand, not shown.

Durch die offene Unterseite des Anschlussraums 34 führen zwei Wasserzufuhrleitungen 36 für Warmwasser beziehungsweise für Kaltwasser in den Anschlussraum 34. In Figur 1 ist eine der Wasserzufuhrleitungen 36 durch die andere verdeckt. Im Anschlussraum 34 sind die Wasserzufuhrleitungen 36 über eine insgesamt mit dem Bezugszeichen 38 versehene Anschlusseinrichtung mit den Durchgangsbohrungen 81 des Bodeneinsatzes 80 verbunden. Die Wasserzufuhrleitungen 36 kommen von einer nicht gezeigten bekannten Warmwasser- beziehungsweise Kaltwasserhausleitung.Through the open bottom of the connection space 34 lead two water supply lines 36 for hot water or cold water in the connection space 34th In FIG. 1 one of the water supply lines 36 is hidden by the other. In the connection space 34, the water supply lines 36 are connected to the through-holes 81 of the bottom insert 80 via a connection device provided overall with the reference number 38. The water supply lines 36 come from a known hot water or Kaltwasserhausleitung not shown.

Oberhalb des Anschlussraums 34 ist auf der Innenmantelfläche des Armaturengehäuses 16 ein umlaufender Auflagekragen 40 angeordnet. Der Außenmantel des Bodeneinsatzes 80 verfügt dort über eine zum Auflagekragen 40 komplementäre umlaufende Auflagestufe 42, mit welcher der Bodeneinsatz 80 von oben her an dem Auflagekragen 40 anliegt. Ein verjüngter unterer Anschlussbereich 44 des Bodeneinsatzes 80, welcher Teil der Anschlusseinrichtung 38 ist, ragt im Anschluss an die Auflagestufe 42 über den Auflagekragen 40 hinaus bis in den Anschlussraum 34.Above the connection space 34, a circumferential support collar 40 is arranged on the inner circumferential surface of the fitting housing 16. The outer casing of the bottom insert 80 has there a circumferential support step 42 complementary to the support collar 40, with which the bottom insert 80 rests against the support collar 40 from above. A tapered lower connection region 44 of the bottom insert 80, which is part of the connection device 38, projects beyond the support collar 40 beyond the support step 42 into the connection space 34.

Der Anschlussbereich 44 ist auf der dem Wasserauslauf 46 der Einhebelmischbatterie 10 abgewandten Seite in radialer Richtung gegenüber dem Hauptteil des Bodeneinsatzes 80 gekürzt. Auf diese Weise ist dort ein weiter unten näher erläuterter Führungsspalt 48 für eine Klemmfeder 50 bei ausgebautem Bodeneinsatz 80 von außen frei zugänglich.The connection region 44 is shortened in the radial direction with respect to the main part of the bottom insert 80 on the side facing away from the water outlet 46 of the single-lever mixer 10. In this way, there is a further explained below guide gap 48 for a clamping spring 50 with removed bottom insert 80 from the outside freely accessible.

Der Bodeneinsatz 80 und die Steuerkartusche 18 sind von der auf der Seite der Kugelhaube 20 offenen Seite in das Armaturengehäuse 16 eingeschoben und werden durch einschrauben eines ringförmigen Schraubteils 84 in ein Gewinde in der Mantelfläche des Aufnahmeraums 14 fixiert. Dabei wird der Bodeneinsatz 80 mit seiner umlaufende Auflagestufe 42 gegen den Auflagekragen 40 gedrückt.The bottom insert 80 and the control cartridge 18 are inserted from the open on the side of the ball cap 20 side in the fitting housing 16 and are fixed by screwing an annular screw member 84 into a thread in the lateral surface of the receiving space 14. In this case, the bottom insert 80 is pressed with its peripheral support step 42 against the support collar 40.

Der Bodeneinsatz 80 ist gegenüber dem Armaturengehäuse 16 abgedichtet. Die Außenmantelfläche des Bodeneinsatzes 80 weist hierfür auf der dem Aufnahmeraum 14 zugewandten Seite eine umlaufende Gehäusenut 54 auf. In der Gehäusenut 54 ist eine entsprechende O-Ring-Dichtung 56 angeordnet, welche die wasserführenden Bereiche nach außen abdichten.The bottom insert 80 is sealed relative to the fitting housing 16.

Auf der oberen Stirnseite weisen die Durchgangsbohrungen 81 jeweils eine Verengung auf, welche als Anschlag dient, an die das eingesteckte Anschlussstück 74 der jeweiligen Wasserzulaufleitung 36 anstößt.In the line receptacles 70 from below below connecting pieces 74 of the water pipes 36 are inserted. On the upper end face, the through holes 81 each have a constriction, which serves as a stop against which the inserted connection piece 74 of the respective water supply line 36 abuts.

Im Bodeneinsatz 80 erstreckt sich der Führungsspalt 48 zwischen den Leitungsaufnahmen 70. Der Führungsspalt 48 hat im Querschnitt, der in der Figur 2 entlang der Schnittlinie II-II aus den Figuren 1 und 3 gezeigt ist, insgesamt etwa die Form eines gleichschenkligen Trapezes mit nicht geradlinigen Schenkeln. Die breite Grundseite des Trapezes ist zu der dem Wasserauslauf 46 abgewandten Seite des Anschlussbereichs 44 der Steuerkartusche 18 hin offen. Die Schenkel des Trapezes verlaufen leicht nach außen gebogen und schneiden die jeweilige Leitungsaufnahme 70 auf der Seite, die der jeweils anderen Leitungsaufnahme 70 abgewandt ist.In the bottom insert 80, the guide gap 48 extends between the line receptacles 70. The guide gap 48 has in cross-section, in the FIG. 2 along the section line II-II from the FIGS. 1 and 3 is shown, overall approximately the shape of an isosceles trapezium with non-straight thighs. The wide base side of the trapezoid is open to the side facing away from the water outlet 46 side of the connection portion 44 of the control cartridge 18. The legs of the trapezoid are slightly bent outward and cut the respective line receptacle 70 on the side facing away from the other line receptacle 70.

Die Wasserleitungen 36 weisen jeweils an ihren Enden eines der kreiszylindrischen Anschlussstücke 74 auf, deren Außendurchmesser den Innendurchmessern der Leitungsaufnahmen 70 entsprechen. Jedes Anschlussstück 74 ist mit einer außen umlaufenden Klemmnut 76 versehen, welche in eingebautem Zustand des Anschlussstücks 74 mit dem Führungsspalt 48 fluchtet.The water pipes 36 each have, at their ends, one of the circular-cylindrical connecting pieces 74, the outer diameters of which correspond to the inner diameters of the pipe supports 70. Each connecting piece 74 is provided with an outer circumferential clamping groove 76 which is aligned with the guide gap 48 in the installed state of the connecting piece 74.

Zur Fixierung der Anschlussstücke 74 und damit der Wasserleitungen 36 in den Leitungsaufnahmen 70 ist die aus rundem Draht gebogene Klemmfeder 50 von der dem Wasserauslauf 46 abgewandten Seite in den Führungsspalt 48 eingeschoben.To fix the connecting pieces 74 and thus the water lines 36 in the line receptacles 70, the bent wire round spring 50 is inserted from the water outlet 46 side facing away from the guide gap 48.

Die Klemmfeder 50 ist im Querschnitt, wie in Figur 2 gezeigt, etwa C-förmig und bezüglich einer zwischen ihren Schenkeln verlaufenden Mittelebene symmetrisch. Die Schenkel der Klemmfeder 50 sind jeweils S-förmig gebogen. Auf ihre freien Enden zu betrachtet weisen die Schenkel jeweils eine vom jeweils anderen Schenkel aus betrachtet konvexe, nach außen offene Einbuchtung 86 auf. Die Einbuchtungen 86 liegen in eingebautem, gespanntem Zustand der Klemmfeder 50 in den Klemmnuten 76 der Anschlussstücke 74 an. Sie umgreifen die Anschlussstücke 74 jeweils von dem anderen Anschlussstück 74 aus betrachtet teilumfänglich und fixieren so die Anschlussstücke 74 in axialer Richtung in den Leitungsaufnahmen 70.The clamping spring 50 is in cross section, as in FIG. 2 shown approximately C-shaped and symmetrical with respect to a median plane extending between its legs. The legs of the clamping spring 50 are each bent in an S-shape. Viewed at their free ends, the legs each have a convex, outwardly open indentation 86 viewed from the other leg. The indentations 86 are in the installed, tensioned state of the clamping spring 50 in the clamping grooves 76 of the connecting pieces 74 at. They embrace the connecting pieces 74, viewed in each case from the other connecting piece 74, partially and thus fix the connecting pieces 74 in the axial direction in the line receptacles 70th

An ihren Enden sind die Schenkel der Klemmfeder 50 nach innen aufeinander zu gebogen, so dass sie beim Einschieben in den Führungsspalt 48, wobei sie gespannt werden, leichter in den Klemmnuten 76 der Anschlussstücke 74 gleiten.At their ends, the legs of the clamping spring 50 are bent inwardly toward each other, so that they slide easily in the clamping grooves 76 of the connecting pieces 74 when inserted into the guide gap 48, wherein they are stretched.

In den Außenmantelflächen jedes Anschlussstücks 74 befindet sich ferner in Längsrichtung betrachtet etwa mittig zwischen der Klemmnut 76 und dem freien Ende des Anschlussstücks 74 eine Umfangs-Dichtnut, in der ein Dichtring 78 angeordnet ist. Mit den Dichtringen 78 sind die Leitungsaufnahmen 70 jeweils nach außen zum Anschlussraum 34 hin abgedichtet.In the outer circumferential surfaces of each connecting piece 74 is also viewed in the longitudinal direction approximately centrally between the clamping groove 76 and the free end of the connecting piece 74, a circumferential sealing groove, in which a sealing ring 78 is arranged. With the sealing rings 78, the cable receptacles 70 are each sealed to the outside to the connection space 34.

Zur Montage der Einhebelmischarmatur 10 wird der mit den O-Ring Dichtungen 56 versehene Bodeneinsatz 80 in den Aufnahmeraum 14 eingeschoben, so dass seine umlaufende Auflagestufe 42 an dem Auflagekragen 40 anliegt. Die Steuerkartusche 18 wird auf den Bodeneinsatz 80 aufgesetzt. Das ringförmige Schraubteil 84 wird in das Gewinde in der Mantelfläche des Aufnahmeraums 14 geschraubt, wodurch die Steuerkartusche 18 den Bodeneinsatz 80 gegen den Auflagekragen 40 presst und fixiert. Dann wird der Mischhebel montiert.To assemble the single-lever mixing fitting 10, the bottom insert 80 provided with the O-ring seals 56 is inserted into the receiving space 14 so that its peripheral support step 42 bears against the support collar 40. The control cartridge 18 is placed on the bottom insert 80. The annular screw member 84 is screwed into the thread in the lateral surface of the receiving space 14, whereby the control cartridge 18 presses and fixes the bottom insert 80 against the support collar 40. Then the mixing lever is mounted.

Zum Anschluss der Wasserleitungen 36 werden diese vom Anschlussraum 34 her, in Figur 1 von unten, mit ihren mit den Dichtringen 78 versehenen Anschlussstücken 74 bis zu der Verengung in die jeweilige Leitungsaufnahme 70 im Bodeneinsatz 80 eingesteckt. Anschließend wird die Klemmfeder 50 vom Anschlußraum 34 her von der offenen Grundseite des Führungsspaltes 48 aus mit ihren Schenkeln voran in diesen eingeschoben. Hierbei gleiten die gebogenen Enden der Klemmfeder 50 unter Spannung an den Klemmnuten 76 entlang bis die Einbuchtungen 86 in die Klemmnuten 76 eingreifen. Die Klemmfeder 50 fixiert nun beide Anschlussstücke 74 gleichzeitig in axialer Richtung im Bodeneinsatz 80.To connect the water pipes 36, these are from the connection space 34 ago, in FIG. 1 from below, plugged with their provided with the sealing rings 78 fittings 74 to the constriction in the respective line receptacle 70 in the bottom insert 80. Subsequently, the clamping spring 50 from the terminal space 34 forth from the open base side of the guide gap 48 with their Thighs pushed forward in these. In this case, the curved ends of the clamping spring 50 slide under tension along the clamping grooves 76 until the indentations 86 engage in the clamping grooves 76. The clamping spring 50 now fixes both connecting pieces 74 simultaneously in the axial direction in the bottom insert 80.

Zuletzt erfolgt die Befestigung der kompletten Einhebelmischbatterie 10 am Waschtisch.Finally, the attachment of the complete single lever mixer 10 takes place on the washstand.

Bei dem oben beschriebenen Ausführungsbeispiel einer Einhebelmischbatterie 10 ist unter anderem folgende Modifikation möglich:In the above-described embodiment of a single-lever mixing battery 10, the following modification is possible, inter alia:

Anstelle der C-förmigen Klemmfedern 50 aus rundem Draht können auch andersartige Klemmfederelemente beispielsweise aus rechteckigem Draht oder Stanzteile verwendet werden.Instead of the C-shaped clamping springs 50 of round wire and other types of clamping spring elements, for example, rectangular wire or stampings can be used.

Der Bodeneinsatz 80 kann statt aus Kunststoff auch aus einem andersartigen Material, beispielsweise aus Messing sein.The bottom insert 80 may be made of a different material, such as brass instead of plastic.
