Description

Die Erfindung betrifft eine Sanitärarmatur, insbesondere eine Waschtischarmatur, nach dem Oberbegriff des Anspruchs 1.The invention relates to a sanitary fitting, in particular a washbasin fitting, according to the preamble of claim 1.

Bei bekannten Sanitärarmaturen wird ein Wasserauslaufgehäuse mit einem Einsteckstutzen von oben beispielsweise in eine Öffnung eines Waschtisches eingesteckt. Das Funktionsbauteil, beispielsweise ein Ventilblock und ein daran befestigter Mischblock, wird von unten an dem Einsteckstutzen befestigt. Der Monteur benötigt üblicherweise zum Halten des Funktionsbauteils beide Hände, da das Funktionsbauteil oft sehr schwer und unhandlich und im Verhältnis zum Einbauraum relativ groß ist. Darüber hinaus ist der Bereich unterhalb des Waschtisches häufig schlecht zugänglich. Der Monteur hat zum Befestigen, Justieren und Verschrauben dann allerdings keine Hand mehr frei.In known sanitary fittings, a water outlet housing is inserted with an insert from above, for example, in an opening of a washstand. The functional component, for example a valve block and a mixing block attached thereto, is fastened to the insertion stub from below. The fitter usually requires both hands to hold the functional component, since the functional component is often very heavy and unwieldy and relatively large in relation to the installation space. In addition, the area below the wash basin is often difficult to access. However, the installer then has no hand free for attaching, adjusting and screwing.

Die EP 1 039 043 A2 beschreibt eine Sanitärarmatur mit einer Mutter zu deren Befestigung an einem Waschtisch. Die Mutter weist Federzungen auf, die derart abgewinkelt sind, dass die Mutter einfach von unten auf einen Gewindeschaft aufschiebbar ist, jedoch infolge der Rastwirkung der Federzungen dann von selbst hält. Mittels zweier Schrauben lässt sich die Mutter dann derart gegen den Waschtisch anlegen, dass die Vorspannung der Federzungen erhöht wird und so die Sanitärarmatur, welche am Gewindeschaft befestigt ist, an den Waschtisch spannt.The EP 1 039 043 A2 describes a sanitary fitting with a nut for attachment to a washstand. The mother has spring tongues which are angled so that the nut is simply pushed from below onto a threaded shaft, but then held by itself as a result of the locking action of the spring tongues. By means of two screws, the nut can then be applied against the washstand so that the bias of the spring tongues is increased, thus tensioning the sanitary fitting, which is attached to the threaded shaft, to the washstand.

Ebenfalls mit der Befestigung von Sanitärarmaturen an einem Waschtisch befassen sich die US 2003/0 051 758 A1 und die US 5 718 464 . Dort sind Lösungen angegeben, wie ein Auslaufkörper der Sanitärarmatur drehbar mit dem Armaturengehäuse verbindbar ist.Also with the attachment of sanitary fittings to a vanity are concerned US 2003/0 051 758 A1 and the US 5,718,464 , There solutions are given as an outlet body of the sanitary fitting is rotatably connected to the valve body.

Die US 4,852,192 A1 zeigt eine Sanitärarmatur, die zur Befestigung an einem Waschtisch einen Einsteckstutzen aufweist, über welchen von unten teleskopartig ein Befestigungs- und Anschlussteil axial übergeschoben wird, wobei zwischen dem Einsteckstutzen und dem Befestigungs- und Anschlussteil ein Dichtring vorgesehen ist. In dieses Befestigungs- und Anschlussteil wird dann von unten ein Schraubeinsatz eingesetzt, welcher mit einem Innengewinde des Einsteckstutzens der Sanitärarmatur zusammenarbeitet, um das Befestigungs- und Anschlussteil gegen den Waschtisch zu pressen.The US 4,852,192 A1 shows a sanitary fitting, which has a Einsteckstutzen for attachment to a vanity over which telescopically from below a mounting and connecting part is axially pushed over, wherein between the plug and the mounting and connecting part, a sealing ring is provided. In this mounting and connecting part is then inserted from below a screw, which with a Internal thread of the Einsteckstutzens the sanitary fitting cooperates to press the mounting and connecting part against the washstand.

Aus der DE 33 24 603 C1 ist eine Auslaufarmatur bekannt, bei der ein schwenkbarer Auslaufarm ein Einsteckendteil hat, das unter Verwendung von Dichtringen in einen oberhalb des Waschtisches angeordneten Auslaufstutzen gesteckt wird. Ein Fixierung in axialer Richtung wird dabei über einen in eine Radialbohrung des Auslaufstutzen eingeschraubten Zapfen erreicht, der mit einer Nut des Einsteckendteils zusammenarbeitet.From the DE 33 24 603 C1 an outlet fitting is known in which a pivotable outlet arm has a Einsteckendteil, which is inserted using sealing rings in a arranged above the washstand outlet nozzle. A fixation in the axial direction is achieved via a screwed into a radial bore of the outlet spigot, which cooperates with a groove of the Einsteckendteils.

Aufgabe der vorliegenden Erfindung ist es, eine Sanitärarmatur der eingangs genannten Art so auszugestalten, dass eine schnelle und technisch einfach Montage ermöglicht wird.Object of the present invention is to provide a sanitary fitting of the type mentioned in such a way that a quick and easy installation is made possible.

Diese Aufgabe wird erfingdungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Erfingdungsgemäß ist also eine Klemmeinrichtung vorgesehen, mit der das Funktionsbauteil mit einem Handgriff an dem Wasserauslaufgehäuse vorfixiert werden kann, so dass der Monteur für die anschließende Befestigung, Justage und Verschraubung beide Hände frei hat. Mit der Spanneinrichtung können anschließend das Wasserauslaufgehäuse und das Funktionsbauteil gegeneinander verspannt werden. So können auch schwere und in Relation zum Einbauraum sperrige Funktionsbauteile oder komplizierte Funktionsbauteile mit wenigen Handgriffen schnell und einfach montiert werden.This object is achieved according to the invention by the features of claim 1. According to the invention, therefore, a clamping device is provided, with which the functional component can be prefixed with a handle on the water outlet housing, so that the fitter has both hands free for the subsequent attachment, adjustment and screwing. With the clamping device then the water outlet housing and the functional component can be braced against each other. Thus, heavy and in relation to the installation space bulky functional components or complicated functional components can be mounted quickly and easily with a few simple steps.

Erfindungsgemäß umfasst das Funktionsbauteil einen Ventilblock und/oder einen Mischblock. Ventilblöcke und daran befestigte Mischblöcke sind schwere und unhandliche Bauteile, die mit der Verbindungseinrichtung besonders einfach mit dem Wasserauslaufgehäuse verbunden werden können.According to the invention, the functional component comprises a valve block and / or a mixing block. Valve blocks and mixing blocks attached thereto are heavy and cumbersome components that can be connected to the connection device particularly simple with the water outlet housing.

Bei einer besonders vorteilhaften Ausführungsform umfasst die Klemmeinrichtung folgende zusammenwirkende Bauteile:

  1. a) wenigstens eine Klemmfeder;
  2. b) eine erste an die Klemmfeder angepasste Nut in einem ersten Bauteil, insbesondere eine Flanschnut in einem mit dem Funktionsbauteil verbundenen Federflansch;
  3. c) eine zweite an die Klemmfeder angepasste, der ersten Nut zugewandte Nut in einem relativ zu dem ersten Bauteil verschiebbaren zweiten Bauteil, insbesondere eine Gehäusenut im Wasserauslaufgehäuse.
In a particularly advantageous embodiment, the clamping device comprises the following interacting components:
  1. a) at least one clamping spring;
  2. b) a first groove adapted to the clamping spring in a first component, in particular a flanged groove in a spring flange connected to the functional component;
  3. c) a second adapted to the clamping spring, the first groove facing groove in a relative to the first component displaceable second component, in particular a housing groove in the water outlet housing.

Eine Klemmfeder und Nuten sind technisch besonders einfach realisierbar und robust.A clamping spring and grooves are technically particularly easy to implement and robust.

Um die vorfixierten Bauteile einfach und ohne großen technisch Aufwand miteinander verspannen zu können, umfasst die Spanneinrichtung wenigstens eine Verbindungsschraube und ein entsprechendes Gewinde, mit denen das erste Bauteil, insbesondere der Federflansch, mit dem Funktionsbauteil spannbar verbunden ist.To clamp the prefixed components easily and without great technical effort, the clamping device comprises at least one connecting screw and a corresponding thread, with which the first component, in particular the spring flange, is connected to the functional component clamped.

Eine deutlich schnellere Montage wird ermöglicht, wenn eine Gewindefeder zur Aufnahme der Verbindungsschraube vorgesehen ist, in die die Verbindungsschraube ohne zu schrauben schnell eingesteckt werden kann. Zum Verspannen kann die Verbindungsschraube anschließend nachgezogen werden.A much faster assembly is made possible if a threaded spring is provided for receiving the connecting screw into which the connecting screw can be inserted quickly without screwing. To tighten the connecting screw can then be tightened.

Um zu verhindern, dass die Verbindungseinrichtung insbesondere bei großen Zugbelastungen durch schwere Funktionsbauteile von dem Wasserauslaufgehäuse abrutscht, kann die Klemmeinrichtung eine insbesondere progressive Selbstsicherungseinrichtung, insbesondere wenigstens eine Führungsschräge für die Klemmfeder, insbesondere für wenigstens einen Führungsstift der Klemmfeder, aufweisen, mit der bei zunehmenden Zug auf die Klemmeinrichtung deren Klemmwirkung verbessert wird.In order to prevent the connecting device from slipping off the water outlet housing, in particular in the case of heavy tensile loads due to heavy functional components, the clamping device can have a particularly progressive self-locking device, in particular at least one guide bevel for the clamping spring, in particular for at least one guide pin of the clamping spring, with which the train increases on the clamping device whose clamping effect is improved.

Vorteilhafterweise weist die Verbindungseinrichtung wenigstens eine Fixiereinrichtung zum Fixieren der Winkellage des Funktionsbauteils relativ zum Wasserauslaufgehäuse, insbesondere einen Fixierstift und eine mit diesem zusammenwirkende Fixierstiftaufnahme, auf. Auf diese Weise wird sichergestellt, dass das Funktionsbauteil in der richtigen Position am Wasserauslaufgehäuse anliegt.Advantageously, the connecting device has at least one fixing device for fixing the angular position of the functional component relative to the water outlet housing, in particular a fixing pin and a fixing pin receptacle cooperating therewith. In this way it is ensured that the functional component rests in the correct position on the water outlet housing.

Das Wasserauslaufgehäuse kann mit einer Formdichtung gegen das Funktionsbauteil abgedichtet sein.The water outlet housing may be sealed with a molded seal against the functional component.

Auf Höhe der Gehäusenut 10 ist ein hohlzylinderförmiger Federflansch 11 als Teil der Verbindungseinrichtung 7 koaxial auf dem Mantel des Einsteckstutzens 25 angeordnet. Der Federflansch 11 hat einen ellipsenähnlichen Außenquerschnitt und einen kreisförmigen Innenquerschnitt (Figur 4), so dass zwei gegenüberliegende Wandverdickungen realisiert sind. Der Innenquerschnitt des Federflansches 11 entspricht dem Außenquerschnitt des Einsteckstutzens 25.At the level of the housing groove 10, a hollow cylindrical spring flange 11 is arranged as part of the connecting device 7 coaxially on the jacket of the Einsteckstutzens 25. The spring flange 11 has an ellipse-like outer cross section and a circular inner cross section ( FIG. 4 ), so that two opposite wall thickenings are realized. The inner cross section of the spring flange 11 corresponds to the outer cross section of the Einsteckstutzens 25th

In den Wandverdickungen ist jeweils eine durchgängige Gewindebohrung 19 angeordnet, deren Achsen parallel zur Achse des Federflansches 11 verlaufen.In the wall thickenings in each case a continuous threaded bore 19 is arranged, whose axes are parallel to the axis of the spring flange 11.

Entlang seiner Innenmantelfläche ist im Federflansch 11 gegenüber der Gehäusenut 10 eine umlaufende Flanschnut 12 angeordnet. Die Flanschnut 12 ist in axialer Richtung des Federflansches 11 etwa doppelt so breit wie die Gehäusenut 10 (Figur 3).Along its inner lateral surface, a peripheral flanged groove 12 is arranged in the spring flange 11 with respect to the housing groove 10. The Flanschnut 12 is about twice as wide in the axial direction of the spring flange 11 as the housing groove 10 ( FIG. 3 ).

Darüber hinaus weist der Federflansch 11 im Boden der Flanschnut 12 eine radial verlaufende durchgängige Klemmfederstiftöffnung 13 (Figur 1) und auf der gegenüberliegenden Seite ebenfalls im Boden der Flanschnut 12 eine radial verlaufenden durchgängige Klemmfedervorsprungsöffnung 14 auf (Figur 4).In addition, the spring flange 11 in the bottom of Flanschnut 12 a radially extending continuous Klemmfederstiftöffnung 13 ( FIG. 1 ) and on the opposite side also in the bottom of Flanschnut 12 a radially extending continuous Klemmfedervorsprungsöffnung 14 ( FIG. 4 ).

In dem durch die Gehäusenut 10 und die Flanschnut 12 gebildeten Raum befindet sich eine geschlitzte, ringförmige Klemmfeder 15 mit rundem Profil (Figur 3).In the space formed by the housing groove 10 and the flange groove 12 is a slotted, annular clamping spring 15 with a round profile ( FIG. 3 ).

Der Durchmesser der Klemmfeder 15 ist in ihrem entspannten Zustand kleiner als der Außendurchmesser des Einsteckstutzens 25, so dass er sich in der Gehäusenut 10 verspannt. Der Profildurchmesser der Klemmfeder 15 ist etwa doppelt so groß wie die Tiefe der Gehäusenut 10 in radialer Richtung des Einsteckstutzens 25, so dass die äußere Profilhälfte der Klemmfeder 15 über den Rand der Gehäusenut 10 in die Flanschnut 12 hineinragt. Auf diese Weise wird verhindert, dass der Federflansch 11 relativ zum Einsteckstutzen 25 in Figuren 1, 2, 3 nach oben oder unten verrutschen kann. Die Klemmfeder 15, die Gehäusenut 10 und die Flanschnut 11 wirken so als Klemmeinrichtung.The diameter of the clamping spring 15 is smaller in its relaxed state than the outer diameter of the Einsteckstutzens 25 so that it is braced in the housing groove 10. The profile diameter of the clamping spring 15 is about twice as large as the depth of the housing groove 10 in the radial direction of the Einsteckstutzens 25, so that the outer profile half of the clamping spring 15 projects beyond the edge of the housing groove 10 in the flanged groove 12. In this way it is prevented that the spring flange 11 relative to the insertion piece 25 in FIGS. 1 . 2 . 3 can slip up or down. The clamping spring 15, the housing groove 10 and the flange groove 11 thus act as a clamping device.

Außerdem ist der Profildurchmesser der Klemmfeder 15 etwas kleiner als die Tiefe der Flanschnut 12 in radialer Richtung des Federflansches 11, so dass die Klemmfeder 15, sofern sie radial nach außen aufgebogen wird, vollständig in die Flanschnut 12 versenkt und der Federflansch 11 vom Einsteckstutzen 25 abgezogen werden kann.In addition, the profile diameter of the clamping spring 15 is slightly smaller than the depth of the flange groove 12 in the radial direction of the spring flange 11, so that the clamping spring 15, if it is bent radially outwards, completely sunk into the flange groove 12 and the spring flange 11 deducted from the insertion piece 25 can be.

Die beiden Enden der Klemmfeder 15 ragen etwa in radialer Richtung des Federflansches 11 nach außen und bilden so zwei Führungsstifte 16 (Figur 4).The two ends of the clamping spring 15 protrude outward approximately in the radial direction of the spring flange 11 and thus form two guide pins 16 (FIG. FIG. 4 ).

Auf der gegenüberliegenden Seite der Führungsstifte 16 weist die Klemmfeder 15 einen in Figur 4 quadratischen Klemmfedervorsprung 17 auf. Der Klemmfedervorsprung 17 ist aus zwei parallelen, im Wesentlichen in radialer Richtung des Federflansches 11 nach außen gebogenen Bereichen der Klemmfeder 15 gebildet, deren radial äußeren Enden einstückig miteinander verbunden sind.On the opposite side of the guide pins 16, the clamping spring 15 has an in FIG. 4 square clamping spring projection 17 on. The Klemmfedervorsprung 17 is formed of two parallel, substantially in the radial direction of the spring flange 11 outwardly bent portions of the clamping spring 15, the radially outer ends are integrally connected to each other.

Die Führungsstifte 16 ragen durch die Klemmfederstiftöffnung 13 und der Klemmfedervorsprung 17 ragt, durch die Klemmfedervorsprungsöffnung 14 hindurch, über die äußeren Mantelfläche des Federflansches 11 hinaus, so dass die Klemmfeder 15 in der Flanschnut 12 gehalten wird.The guide pins 16 protrude through the Klemmfederstiftöffnung 13 and the Klemmfedervorsprung 17 projects through the Klemmfedervorsprungsöffnung 14 through, beyond the outer surface of the spring flange 11 also, so that the clamping spring 15 is held in the flange groove 12.

Die Führungsstifte 16 können von außerhalb des Federflansches 11 auseinander gedrückt werden, um den Durchmesser der Klemmfeder 15 zu vergrößern und diese so in der Flanschnut 12 zu versenken.The guide pins 16 can be pressed apart from outside the spring flange 11 in order to increase the diameter of the clamping spring 15 and to sink them in the flanged groove 12 so.

Der Querschnitt der Klemmfederstiftöffnung 13 hat die Form eines Dreiecks, dessen Spitze nach oben zeigt (Figur 1, 2). Die beiden oberen Schenkelflächen der Klemmfederstiftöffnung 13 bilden jeweils eine Führungsschräge 18 für den entsprechenden Führungsstift 16 der Klemmfeder 15. Wird die Klemmfeder 15 relativ zum Federflansch 11 in Figuren 1, 2 nach oben verschoben, so werden die Führungsstifte 16 entlang der Führungsschrägen 18 geführt und aufeinander zu bewegt, so dass sich der Durchmesser der Klemmfeder 15 zunehmend verkleinert und die Klemmfeder 15 in die Gehäusenut 10 gepresst wird. Dies ist der Fall, wenn der Federflansch 11 relativ zum Wasserauslaufgehäuse 2 in Figuren 1, 2, 3 nach unten gezogen wird. Auf diese Weise wird bei Zug nach unten eine progressive Selbstsicherung des Federflansches 11 auf dem Einsteckstutzen 25 realisiert.The cross-section of the clamping spring pin opening 13 has the shape of a triangle, the tip of which points upwards ( FIG. 1, 2 ). The two upper leg surfaces of the clamping spring pin opening 13 each form a guide bevel 18 for the corresponding guide pin 16 of the clamping spring 15 is the clamping spring 15 relative to the spring flange 11 in FIGS. 1 . 2 shifted upwards, the guide pins 16 are guided along the guide slopes 18 and moved toward each other, so that the diameter of the clamping spring 15 is increasingly reduced and the clamping spring 15 is pressed into the housing groove 10. This is the case when the spring flange 11 relative to the water outlet housing 2 in FIGS. 1 . 2 . 3 is pulled down. In this way, a progressive self-assurance of the spring flange 11 is realized on the insertion piece 25 at train down.

Die Klemmfederstiftöffnung 13 weist in ihrer Grundfläche eine Öffnung zur unteren Stirnseite des Federflansches 11 auf. Beim werkseitigen Einbringen der Klemmfeder 15 in die Gehäusenut 10 werden die Führungsstifte 16 durch diese Öffnung hindurch in die Klemmfederstiftöffnung 13 geführt.The Klemmfederstiftöffnung 13 has in its base an opening to the lower end face of the spring flange 11. During factory insertion of the clamping spring 15 in the housing groove 10, the guide pins 16 are guided through this opening into the Klemmfederstiftöffnung 13.

In den Gewindebohrungen 19 des Federflansches 11 befindet sich jeweils eine Verbindungsschraube 20, vorzugsweise eine Innensechskantschraube, mit denen der Federflansch 11 mit dem Ventilblock 4 verschraubt ist.In the threaded holes 19 of the spring flange 11 is in each case a connecting screw 20, preferably a hexagon socket screw, with which the spring flange 11 is bolted to the valve block 4.

Im Ventilblock 4 sind zwei Durchgangsbohrungen 21 für die Verbindungsschrauben 20 vorgesehen, deren Achsen jeweils koaxial zu den Achsen der Gewindebohrungen 19 verlaufen. Die Köpfe der Verbindungsschrauben 20 sind in Figuren 1, 2, 3 unterhalb des Ventilblocks 4 positioniert. Durch die Verbindungsschrauben 20, die Gewindebohrungen 19 und die Durchgangsbohrungen 21 wird eine Spanneinrichtung realisiert.In the valve block 4, two through holes 21 are provided for the connecting bolts 20, whose axes each extend coaxially to the axes of the threaded bores 19. The heads of the connecting screws 20 are in FIGS. 1 . 2 . 3 positioned below the valve block 4. By the connecting screws 20, the threaded holes 19 and the through holes 21 a clamping device is realized.

Der Ventilblock 4 hat im Wesentlichen die Form eines Quaders. Aus seiner in Figur 3 oberen Stirnseite geht eine hohlzylinderförmige Steckaufnahme 26 hervor, in die die Verjüngung 28 des Wasserauslaufgehäuses 2 eingesteckt ist. Der Innendurchmesser der Steckaufnahme 26 entspricht dem Außendurchmesser der Verjüngung 28 des Einsteckstutzens 25. Die Verjüngung 28 wird mit dem O-Ring in der Ringnut 30 gegenüber der Steckaufnahme 26 abgedichtet.The valve block 4 has substantially the shape of a cuboid. From his in FIG. 3 upper end face is a hollow cylindrical plug-in receptacle 26, into which the taper 28 of the water outlet housing 2 is inserted. The inner diameter of the plug-in receptacle 26 corresponds to the outer diameter of the taper 28 of the Einsteckstutzens 25. The taper 28 is sealed with the O-ring in the annular groove 30 opposite the socket 26.

Zwischen der oberen ebenen Stirnseite des Ventilblocks 4 innerhalb der Steckaufnahme 26 und der unteren ebenen Stirnseite des Einsteckstutzens 25 ist eine Formdichtung 22 vorgesehen.Between the upper planar end face of the valve block 4 within the plug-in receptacle 26 and the lower planar end face of the Einsteckstutzens 25 a molded seal 22 is provided.

Darüber hinaus weist die obere Stirnseite des Ventilblocks 4 in einem Bereich innerhalb der Steckaufnahme 26 außerhalb deren Zentrums eine Bohrung 27 für einen Fixierstift 23 auf.In addition, the upper end side of the valve block 4 in a region within the plug-in receptacle 26 outside the center thereof has a bore 27 for a fixing pin 23.

In der unteren Stirnseite des Einsteckstutzens 25 ist eine zu dem Fixierstift 23 komplementäre Fixierstiftaufnahme 24 vorgesehen.In the lower end face of the Einsteckstutzens 25 a complementary to the fixing pin 23 Fixierstiftaufnahme 24 is provided.

Durch den Fixierstift 23 in der Fixierstiftaufnahme 24 wird die Winkelstellung des Ventilblocks 4 gegenüber dem Einsteckstutzen 25 festgelegt.By the fixing pin 23 in the Fixierstiftaufnahme 24, the angular position of the valve block 4 is set relative to the Einsteckstutzen 25.

Um die Sanitärarmatur 1 am Waschtisch zu montieren, wird zunächst der Einsteckstutzen 25 von oben durch die Öffnung des Waschtisches hindurch gesteckt, bis die Unterseite des Gehäuseoberteils 3 auf der Oberseite des Waschtischs anliegt.In order to mount the sanitary fitting 1 on the washstand, first the insertion piece 25 is inserted from above through the opening of the washstand until the bottom of the upper housing part 3 rests on the top of the washstand.

Daraufhin wird das Wasserauslaufgehäuse 2 mit der Haltemutter 9 von unten gegen die Unterseite des Waschtisches verspannt.Then the water outlet housing 2 is braced with the retaining nut 9 from below against the underside of the washstand.

Anschließend wird der Ventilblock 4 mit den beiden Verbindungsschrauben 20 an den Federflansch 11 geschraubt. Der Ventilblock 4 selbst ist mit dem Mischblock 6 in bekannter Weise verschraubt.Subsequently, the valve block 4 is screwed with the two connecting screws 20 to the spring flange 11. The valve block 4 itself is bolted to the mixing block 6 in a known manner.

Nun wird der Federflansch 11 von unten auf die Verjüngung 28 des Wasserauslaufgehäuses 2 aufgesteckt. Hierbei dient die Verjüngung 28 als Aufsteckhilfe für die Klemmfeder 15, die beim Aufstecken zunächst aufgespreizt wird.Now, the spring flange 11 is attached from below to the taper 28 of the water outlet housing 2. Here, the taper 28 serves as Aufsteckhilfe for the clamping spring 15, which is first spread when plugging.

Wegen ihrer Vorspannung taucht die Klemmfeder 15 beim Erreichen der Gehäusenut 10 mit etwa ihrer halben Profil - tiefe in diese ein. Ein weiteres Eindringen wird durch die Tiefe der Gehäusenut 10 begrenzt. Die Klemmfeder 15 befindet sich nun mit ihrer inneren Profilhälfte in der Gehäusenut 10 und mit ihrer äußeren Profilhälfte in der Flanschnut 12, so dass der Federflansch 11 relativ zum Einsteckstutzen 25 axial nahezu fixiert wird. Der Federflansch 11 und der Ventilblock 4 sind so auf dem Einsteckstutzen 25 vorfixiert, dass der Monteur beide Hände frei hat, um die Verbindungsschrauben 20 gleichmäßig weiter in die jeweiligen Gewindebohrungen 19 im Federflansch 11 einzuschrauben.Because of their bias, the clamping spring 15 immersed in reaching the housing groove 10 with about half their profiled - depth in this one. Further penetration is limited by the depth of the housing groove 10. The clamping spring 15 is now with its inner profile half in the housing groove 10 and with its outer profile half in the Flan groove 12, so that the spring flange 11 is almost axially fixed relative to the insertion piece 25. The spring flange 11 and the valve block 4 are pre-fixed on the Einsteckstutzen 25 that the installer has both hands free to evenly screw the connecting bolts 20 into the respective threaded holes 19 in the spring flange 11.

Sobald der Fixierstift 23 an die untere Stirnseite des Einsteckstutzens 25 anstößt, werden der Federflansch 11 und der Ventilblock 4 vom Monteur relativ zum Wasserauslaufgehäuse 2 so gedreht, dass der Fixierstift 23 gegenüber der Fixierstiftaufnahme 24 positioniert ist.Once the fixing pin 23 abuts the lower end face of the Einsteckstutzens 25, the spring flange 11 and the valve block 4 are rotated by the fitter relative to the water outlet housing 2 so that the fixing pin 23 is positioned opposite the Fixierstiftaufnahme 24.

Beim weiteren Anziehen der Verbindungsschrauben 20 dringt der Fixierstift 23 in die Fixierstiftaufnahme 24 ein, der Federflansch 11 wird verspannt und die untere Stirnseite des Einsteckstutzens 25 wird mit der Formdichtung 22 gegen die obere Stirnseite des Ventilblocks 4 abgedichtet.Upon further tightening the connecting screws 20 of the fixing pin 23 penetrates into the Fixierstiftaufnahme 24, the spring flange 11 is clamped and the lower end of the Einsteckstutzens 25 is sealed with the molded seal 22 against the upper end face of the valve block 4.

Durch den Zug am Federflansch 11 wird die Klemmfeder 15 relativ zu Federflansch 11 nach oben bewegt, so dass die beiden Führungsstifte 16 entlang der jeweiligen Führungsschrägen 18 geführt und aufeinander zu bewegt werden. Durch die progressive Selbstsicherung wird verhindert, dass der Federflansch 11 vom Wasserauslaufgehäuse 2 nach unten rutschen kann.By the train on the spring flange 11, the clamping spring 15 is moved relative to the spring flange 11 upwards, so that the two guide pins 16 are guided along the respective guide slopes 18 and moved towards each other. Due to the progressive self-locking prevents the spring flange 11 from the water outlet housing 2 can slide down.

Statt der Gewindebohrungen 19 im Federflansch 11 können auch Bohrungen ohne Gewinde vorgesehen sein, die jeweils eine ein Gewinde nachbildende Gewindefeder aufweisen. Die Gewindefedern sind so angeordnet, dass sie in Einschubrichtung der Verbindungsschrauben 20, nämlich in Figuren 1, 2, 3 von unten nach oben, öffnen. Auf diese Weise können die Verbindungsschrauben 20 ohne geschraubt zu werden schnell eingesteckt werden, wodurch eine deutlich schnellere Montage möglich ist. Sobald die Gewindefedern unter Zug stehen, ziehen sie sich zusammen und sperren die jeweilige Verbindungsschraube 20, so dass diese nicht mehr nach unten aus den Bohrungen im Federflansch 11 heraus gezogen werden können. Anschließend werden die Verbindungsschrauben 20 weiter eingeschraubt, um die Verbindung zu fixieren.Instead of the threaded holes 19 in the spring flange 11 holes without thread can be provided, each having a thread mimicking threaded spring. The thread springs are arranged so that they are in the insertion direction the connecting screws 20, namely in FIGS. 1 . 2 . 3 from bottom to top, open. In this way, the connecting screws 20 can be inserted quickly without being screwed, whereby a much faster assembly is possible. Once the coil springs are under tension, they contract and lock the respective connecting screw 20 so that they can not be pulled down from the holes in the spring flange 11 out. Subsequently, the connecting screws 20 are further screwed in to fix the connection.

Die Gewindebohrungen 19 beziehungsweise die Gewindefedern können statt im Federflansch 11 auch im Ventilblock 4 angeordnet sein.The threaded bores 19 or the threaded springs can be arranged instead of the spring flange 11 in the valve block 4.

Es können auch nur eine oder mehr als zwei Verbindungsschrauben 20 mit entsprechenden Gewindebohrungen 19 beziehungsweise Gewindefedern vorgesehen sein.It is also possible to provide only one or more than two connecting screws 20 with corresponding threaded bores 19 or threaded springs.

Die Klemmfeder 15 kann statt eines runden beispielsweise auch ein flaches oder eckiges Profil aufweisen.The clamping spring 15 may instead of a round, for example, have a flat or square profile.

Statt der Führungsschrägen 18 können auch Führungsschrägen beispielsweise entlang der Flanschnut 12 verlaufen. Beispielsweise kann die obere Wand der Flanschnut 12 umlaufend abgeschrägt sein, so dass die Klemmfeder 15 gleichmäßig radial nach innen gedrückt wird, sobald der Federflansch 11 unter Zug steht. In diesem Fall sind die Führungsstifte 16 nicht erforderlich.Instead of the guide bevels 18, guide bevels can also run, for example, along the flanged groove 12. For example, the upper wall of the flange groove 12 may be chamfered circumferentially, so that the clamping spring 15 is pressed uniformly radially inwardly as soon as the spring flange 11 is under tension. In this case, the guide pins 16 are not required.
