Description

Die Erfindung betrifft eine Mischbatterie für Kalt- und Warmwasser, insbesondere für den Sanitärbereich, mit einem Batteriekörper, der mit Hohlansätzen zur Abdeckung der Anschlußstellen für die Versorgungsleitungen versehen ist, wobei jeweils ein in der zugehörigen Versorgungsleitung angeordneter, aus der Gebäudewand vorstehender Stutzen vorgesehen ist, über welche der Batteriekörper mit Hohlansätzen bei der Installation überschiebbar ist, derart, daß jeder Stutzen von einer Zylinderführung gedichtet und axial beweglich aufgenommen und der Batteriekörper an den durch den Batteriekörper verdeckten Stutzen in der Stecklage fixierbar ist.
Eine derartige Mischbatterie ist aus der deutschen Offenlegungsschrift 17 84 504 bekannt. Bei dieser Ausbildung sind Anschlußnippel vorgesehen, die jeweils mit einem kolbenartigen, zwei O-Ringe tragenden Vorderteil in der Zylinderführung eines Hohlansatzes axial verschiebbar aufgenommen sind. Hierbei kann es jedoch bei der Anmontage der Mischbatterie zu Schwierigkeiten kommen, wenn die Anschlußleitungen in der Gebäudewand Schiefstellungen aufweisen bzw. die Anschlußstücke nicht rechtwinklig aus der Gebäudewand herausgeführt sind.The invention relates to a mixer tap for cold and hot water, in particular for the sanitary area, with a battery body which is provided with hollow attachments for covering the connection points for the supply lines, wherein in each case a connecting piece arranged in the associated supply line and projecting from the building wall is provided, About which the battery body with hollow lugs can be pushed over during installation, such that each socket is sealed by a cylinder guide and axially movably received and the battery body can be fixed in the plug-in position to the socket covered by the battery body.
Such a mixer tap is known from German Offenlegungsschrift 17 84 504. In this embodiment, connecting nipples are provided, each of which is axially displaceably received in the cylinder guide of a hollow extension with a piston-like front part carrying two O-rings. In this case, however, difficulties can arise when installing the mixer tap if the connecting lines in the building wall are out of alignment or the connecting pieces are not led out of the building wall at right angles.

Ferner war aus der FR-A-2 452 659 eine Mischbatterie vorbekannt, bei der das Batteriegehäuse an der von der Wand abgelegenen Seite zu beiden Seiten jeweils eine verschließbare Öffnung aufweist, die als Zugang zu einer Mittenabstandseinstelleinrichtung für die Anschlußrohrstutzen dient. Hierbei ist jeweils eine Platte mit kreisförmigem Querschnitt drehbar und gedichtet im Batteriekörper angeordnet. In jeder der beiden Platten ist ein Anschlußrohrstutzen mit einem Kugelkopf exzentrisch versetzt vorgesehen. Die beiden drehbaren Platten sind dabei jeweils axial festliegend von einem Sprengring im Batteriegehäuse gehalten. Stromabwärts hinter jeder Platte ist ein Vorabsperr- und Justierventil angeordnet, auf dem eine lösbare Abdeckung befestigt ist.
Bei der Installation dieser Mischbatterie sind daher zunächst die beiden Abdeckungen sowie die Vorabsperreinrichtungen aus dem Batteriegehäuse zu entfernen. Erst dann kann die Mischbatterie mit ihrem Gehäuse an die Versorgungsrohrleitungen für Kalt- und Warmwasser angeschlossen werden, wobei die Ausrichtung der Batterie vorzunehmen ist. Abschließend sind dann die beiden Vorabsperreinrichtungen mit den Abdeckungen am Batteriegehäuse wieder anzubringen.Furthermore, a mixer tap was previously known from FR-A-2 452 659, in which the battery housing on the side remote from the wall has a closable opening on both sides, which serves as access to a center-distance setting device for the connecting pipe socket. In this case, a plate with a circular cross section is rotatably arranged and sealed in the battery body. In each of the two plates, a connecting pipe socket with a ball head is provided offset eccentrically. The two rotatable plates are each held axially fixed by a snap ring in the battery housing. Downstream of each plate there is a pre-shut-off and adjustment valve on which a removable cover is attached.
When installing this mixer tap, the two covers and the pre-shut-off devices must therefore be removed from the battery housing. Only then can the mixer tap with its housing be connected to the supply pipes for cold and hot water, with the battery being aligned. Finally, the two pre-shut-off devices with the covers on the battery housing must be reattached.

Der Erfindung liegt die Aufgabe zugrunde, die im Oberbegriff des Anspruchs 1 oder 2 angegebene Mischbatterie zu verbessern und so auszubilden, daß insbesondere auch bei winkelmäßigen Fehlstellungen der Anschlußleitungen eine einfache Installation der Mischbatterie ermöglicht wird.The invention is based on the object in the preamble of claim 1 or 2 specified mixer tap to improve and to train so that especially with angular Misalignment of the connecting lines an easy installation the mixer tap is enabled.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 oder Anspruchs 2 gelöst.This object is achieved with the features of the claim 1 or claim 2 solved.

Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 3 bis 14 angegeben.Further embodiments of the invention are in claims 3 to 14 specified.

Mit den erfindungsgemäß vorgeschlagenen Maßnahmen wird insbesondere erreicht, daß einerseits die Einschraubtiefe der Nippel zur Wandoberfläche von der jeweiligen Wandscheibe exakt festgelegt wird, wobei durch die Kugelkopfausbildungen Schiefstellungen der Rohrleitungen ausgeglichen werden, und andererseits ein einfaches Aufschieben des sichtbaren Batteriekörpers auf die an der Gebäudewand installierten und ausgerichteten Wandscheiben gewährleistet wird, wobei in der Stecklage der Batteriekörper an den dann verdeckten Wandscheiben fixiert werden kann.With the measures proposed according to the invention, in particular achieved that the screw depth of the nipple to the wall surface of the respective wall panel exactly is, with the spherical head misalignments of the pipelines are balanced, and on the other one simply slide the visible battery body onto the the wall panels installed and aligned is guaranteed, with the battery body in the plugged position can then be fixed to the concealed wall panels.

Der Einfachheit halber sind bei den Ausführungsbeispielen in der Zeichnung gleiche oder entsprechende Elemente mit jeweils gleichen Bezugszeichen versehen.
Die in Figur 1 gezeigte Mischbatterie ist nur zum Teil dargestellt. Sie besteht im wesentlichen aus einem Batteriekörper 1, an dem einerseits mit Abstand zueinander zwei Hohlansätze 11 ausgebildet sind, andererseits ein zum Teil dargestelltes Mischventil 13 zur Erzeugung von Mischwasser befestigt ist.
In den Hohlansätzen 11 ist jeweils eine Zylinderführung 111 ausgebildet, in der eine als Baueinheit ausgebildete Wandscheibe 2 axial verschieblich aufgenommen ist. Die Wandscheibe 2 trägt dabei an der Mantelfläche 23 einen Dichtring 22, der mit der Wandung der Zylinderführung 111 dichtend zusammenwirkt. Außerdem ist an der Mantelfläche 23 ein Konus 231 ausgebildet, der jeweils in der Stecklage mit einer im Hohlansatz 11 angeordneten Radialschraube 112 zusammenwirkt, wobei die Radialschraube 112 mit einer entsprechend konischen Stirnfläche 1121 versehen ist, so daß von der Radialschraube 112 die Wandscheibe 2 in der Stecklage im Hohlansatz 11 sicher gehalten ist. For the sake of simplicity, the same or corresponding elements are provided with the same reference numerals in the exemplary embodiments in the drawing.
The mixer tap shown in Figure 1 is only partially shown. It essentially consists of a battery body 1 on which on the one hand two hollow lugs 11 are formed at a distance from one another and on the other hand a mixing valve 13 for producing mixed water, which is shown in part, is attached.
A cylindrical guide 111 is formed in each of the hollow projections 11, in which a wall disc 2 designed as a structural unit is accommodated so that it can move axially. The wall plate 2 carries on the outer surface 23 a sealing ring 22 which cooperates sealingly with the wall of the cylinder guide 111. In addition, a cone 231 is formed on the lateral surface 23, which cooperates in the plug-in position with a radial screw 112 arranged in the hollow shoulder 11, the radial screw 112 being provided with a correspondingly conical end face 1121, so that the wall screw 2 in the radial screw 112 Plug position in the hollow extension 11 is held securely.

Die Wandscheibe 2 ist becherförmig ausgebildet, wobei im Boden 21 exzentrisch zur Mittelachse 20 eine Öffnung in Form einer Kugelpfanne 211 ausgebildet ist. Im Bereich der Kugelpfanne 211 ist außerdem im Boden 21 ein Dichtring 2111 angeordnet.
In der Kugelpfanne 211 ist ein Nippel 3 mit einem Kugelkopf 31 eingelagert. Der Nippel 3 trägt am stromaufwärts gelegenen Endbereich ein Gewinde 32, mit dem er in die Versorgungsleitung (in der Zeichnung nicht dargestellt) einschraubbar ist.
Zur dichten Halterung des Kugelkopfes 31 in der Wandscheibe 2 ist an der stromabwärts liegenden Seite des Bodens 31 ein Druckstück 4 angelagert, in dem ebenfalls eine Kugelpfanne 41 ausgebildet ist. Die Trennebene zwischen Druckstück 4 und dem Boden 21 befindet sich hierbei auf dem Äquator des Kugelkopfes 31. Zur Anpressung der Mantelfläche des Kugelkopfes 31 an den im Boden 21 angeordneten Dichtring 2111 ist eine Ringschraube 42 mittels Gewinde 24 in der Wandscheibe 2 angeordnet, die über das Druckstück 4 und die Kugelpfanne 41 auf den Kugelkopf 31 einwirkt. Alternativ kann auch das Druckstück konzentrisch zur Kugelpfanne angeordnet werden und mittels eines Außengewindes in der Wandscheibe direkt einschraubbar ausgebildet sein.The wall pane 2 is cup-shaped, an opening in the form of a ball socket 211 being formed in the bottom 21 eccentrically to the central axis 20. A sealing ring 2111 is also arranged in the bottom 21 in the region of the ball socket 211.
A nipple 3 with a ball head 31 is embedded in the ball socket 211. The nipple 3 has a thread 32 at the upstream end region, with which it can be screwed into the supply line (not shown in the drawing).
For the tight mounting of the ball head 31 in the wall pane 2, a pressure piece 4 is attached to the downstream side of the bottom 31, in which a ball socket 41 is also formed. The parting plane between the pressure piece 4 and the base 21 is located on the equator of the ball head 31. For pressing the outer surface of the ball head 31 against the sealing ring 2111 arranged in the base 21, an eyebolt 42 is arranged in the wall disk 2 by means of thread 24, which over the Pressure piece 4 and the ball socket 41 acts on the ball head 31. Alternatively, the pressure piece can also be arranged concentrically to the ball socket and can be designed to be screwed directly into the wall pane by means of an external thread.

Die Wandscheibe 2 mit dem eingesetzten Nippel 3 wird zweckmäßig werksseitig als Baueinheit zusammengefügt, so daß am Installationsort der Mischbatterie zunächst jeweils eine Wandscheibe 2 mit einer Kalt- und Warmwasserversorgungsleitung verbunden wird. Hierbei kann zunächst der Nippel 3 mit dem Gewinde 32 nach dem Aufbringen von Hanf und Kitt in das jeweilige Rohrleitungsendstück eingeschraubt werden. Dabei sind in einer zentralen Durchgangsöffnung 33 Kantflächen 34 für den Ansatz eines Innensechskantschlüssels ausgebildet. Beide Nippel 3 werden zunächst soweit in die Endstücke der Rohrleitungen eingeschraubt, bis die Wandscheiben 2 mit ihrer der Gebäudewand zugekehrte Stirnseite mit einem in ihr angeordneten gummielastischen Ring 25 an der Gebäudewand leicht anliegen. Anschließend werden die Wandscheiben 2 soweit zu den Nippeln 3 verdreht, bis ein entsprechendes Stichmaß der Hohlansätze 11 des Batteriekörpers 1 erreicht ist. Danach werden die Nippel 3 weiter in die Endstücke der Rohrleitungen eingeschraubt, bis die Wandscheiben 2 mit den Ringen 25 gedichtet gegen die Gebäudewand gedrückt werden.
Nunmehr kann der Batteriekörper 1 mit den Hohlansätzen 11 und den Zylinderführungen 111 gedichtet auf die Mantelflächen 23 der Wandscheiben 2 aufgeschoben werden. Zur Fixierung in der Stecklage werden hiernach die Radialschrauben 112 eingeschraubt, bis sie jeweils mit ihrer konischen Stirnfläche 1121 an dem Konus 231 anliegen und der Batteriekörper 1 in der Stecklage gesichert ist. Nunmehr kann durch die Durchgangsöffnungen 33 der Nippel 3 Kalt- und Warmwasser über Wasserführungskanäle 12 dem Mischventil 13 zugeführt werden.The wall plate 2 with the inserted nipple 3 is expediently assembled at the factory as a structural unit, so that at the installation location of the mixer tap a wall plate 2 is first connected to a cold and hot water supply line. First, the nipple 3 with the thread 32 can be screwed into the respective pipe end piece after the application of hemp and putty. In this case, 33 edge surfaces 34 are formed in a central through opening for the attachment of an Allen key. Both nipples 3 are first screwed into the end pieces of the pipes until the wall disks 2, with their end faces the building wall, lightly abut the building wall with a rubber-elastic ring 25 arranged therein. The wall disks 2 are then rotated to the nipples 3 until a corresponding internal dimension of the hollow shoulders 11 of the battery body 1 is reached. Then the nipples 3 are screwed further into the end pieces of the pipelines until the wall disks 2 with the rings 25 are pressed against the building wall.
Now the battery body 1 with the hollow shoulders 11 and the cylinder guides 111 can be pushed onto the lateral surfaces 23 of the wall disks 2 in a sealed manner. For fixing in the plug-in position, the radial screws 112 are then screwed in until their conical end face 1121 abuts the cone 231 and the battery body 1 is secured in the plug-in position. Cold and hot water can now be supplied to the mixing valve 13 through the through openings 33 of the nipples 3 via water guide channels 12.

In dem in Figur 2 und 3 gezeigten Ausführungsbeispiel ist eine andere Ausbildung der Wandscheibe 2' mit dem Nippel 3' dargestellt. Die Wandscheibe 2' weist eine von der stromaufwärts gelegenen Stirnseite zugängliche Kugelpfanne 211 auf, in die der Nippel 3' mit einer Kugelzone 31' eingelagert ist. In einer Ringnut ist ein Dichtungsring 2111 auf dem Äquator der Kugelzone 31' angeordnet, wobei der Nippel 3' mit der Kugelzone 31' von einer an der stromaufwärts gelegenen Stirnseite vorgesehenen Ringschraube 42 in der Kugelpfanne 211 gehalten ist. Mit dieser Anordnung der Ringschraube 42 wird bei einem Abmontieren des Batteriekörpers 1 weitgehend ausgeschlossen, daß die Ringschraube 42 versehentlich gelöst wird. Außerdem ist die Ringschraube 42 versenkt in der Wandscheibe 2' angeordnet, so daß eine einwandfreie Abdichtung mit dem gummielastischen Ring 25 zur Gebäudewand gewährleistet ist.
Die Wandscheibe 2' ist ebenfalls mit einem Dichtring 22 in der Zylinderführung 111 des Hohlansatzes 11 des Batteriekörpers 1 gedichtet angeordnet. Damit Unebenheiten der Gebäudewand ausgeglichen werden können, ist im Mantelbereich des Dichtrings 22 eine ballige Führungsfläche 232 vorgesehen, während im übrigen Bereich ein entsprechend großes Spiel zwischen der Zylinderführung 111 und der Mantelfläche 23 vorgesehen ist. Zur Drehausrichtung ist an der stromabwärts gelegenen Stirnseite der Wandscheibe 2' eine Sechskantöffnung 26 für den Einsatz eines Innensechskantschlüssels vorgesehen. An der Mantelfläche 23 ist eine umlaufende Ringnut 231' ausgebildet, in die zur Fixierung des Batteriekörpers 1 in der Stecklage die Radialschraube 112 eindrehbar ist.In the embodiment shown in Figures 2 and 3, a different design of the wall plate 2 'with the nipple 3' is shown. The wall plate 2 'has a ball socket 211 accessible from the upstream end face, in which the nipple 3' is embedded with a ball zone 31 '. A sealing ring 2111 is arranged in an annular groove on the equator of the ball zone 31 ', the nipple 3' with the ball zone 31 'being held in the ball socket 211 by an eyebolt 42 provided on the upstream end face. With this arrangement of the eyebolt 42 is largely excluded when removing the battery body 1 that the eyebolt 42 is accidentally loosened. In addition, the eyebolt 42 is sunk in the wall panel 2 ', so that a perfect seal with the rubber-elastic ring 25 to the building wall is guaranteed.
The wall plate 2 'is also arranged sealed with a sealing ring 22 in the cylinder guide 111 of the hollow extension 11 of the battery body 1. In order to compensate for unevenness in the building wall, a spherical guide surface 232 is provided in the jacket area of the sealing ring 22, while in the remaining area there is a correspondingly large play between the cylinder guide 111 and the jacket surface 23. A hexagonal opening 26 for the use of an Allen key is provided on the downstream end face of the wall pane 2 'for the purpose of rotational alignment. A circumferential annular groove 231 ′ is formed on the lateral surface 23, into which the radial screw 112 can be screwed in in order to fix the battery body 1 in the inserted position.

Der Nippel 3' trägt stromabwärts hinter der Kugelzone 31' einen Fortsatz 35, der in den Batteriekörper 1 geringfügig hineinragt. Am Außenmantel trägt der Fortsatz 35 Schlüsselflächen 34', an die ein Werkzeug zum Einschrauben des Nippels 3' in die Versorgungsleitung angesetzt werden kann.
In der Durchgangsöffnung 33 ist eine bekannte Einrichtung 5 zur Fließgeräuschreduzierung angeordnet.
Außerdem ist in einer Schraubhülse 8, die stromabwärts an der Stirnseite in den Nippel 3' einschraubbar ist, ein Filtersieb 6 und ein bekannter Rückflußverhinderer 7 an die Durchflußöffnung 33 des Nippels 3' angeschlossen.
Die Installation der Wandscheibe 2' kann entsprechend der Beschreibung zu dem in Figur 1 angegebenen Ausführungsbeispiel erfolgen.The nipple 3 'carries an extension 35 downstream behind the ball zone 31', which protrudes slightly into the battery body 1. The extension 35 carries key surfaces 34 'on the outer jacket, to which a tool for screwing the nipple 3' into the supply line can be attached.
A known device 5 for reducing flow noise is arranged in the passage opening 33.
In addition, a filter screen 6 and a known backflow preventer 7 are connected to the flow opening 33 of the nipple 3 'in a screw sleeve 8 which can be screwed downstream into the nipple 3' at the end face.
The wall pane 2 'can be installed in accordance with the description of the exemplary embodiment specified in FIG. 1.
