Durch die Dichtung lässt sich jegliches Eindringen von Wasser in den Armaturengrundkörper an dessen Oberseite vermeiden. Durch die auf die Trägerplatte aufgebrachte Deckplatte braucht die Trägerplatte nicht die Eigenschaften erfüllen, die üblicherweise an außenliegende Teile von sanitären Wasserauslaufarmaturen gestellt werden, beispielsweise hinsichtlich des optischen Erscheinungsbildes. Zudem gibt dies die Möglichkeit, für unterschiedliche Wasserauslaufarmaturen die gleiche Trägerplatte zu verwenden und diese mit unterschiedlichen Deckplatten zu versehen.The seal prevents any ingress of water into the fitting body at its top. Due to the cover plate applied to the carrier plate, the carrier plate does not have to fulfill the characteristics which are usually placed on external parts of sanitary water outlet fittings, for example with regard to the visual appearance. In addition, this gives the possibility to use the same support plate for different water outlet fittings and to provide them with different cover plates.

Für solche Komponenten, die einer periodischen Wartung bedürfen, ist es sehr vorteilhaft, wenn sie leicht zugänglich sind.In order to provide access to the valve unit or the insert element, thus only the top cover needs to be removed from the fitting body. For such components that require periodic maintenance, it is very advantageous if they are easily accessible.
In einer Weiterbildung der Erfindung ist die Dichtung umlaufend axial abdichtend oder umlaufend radial abdichtend ausgeführt. Unter Axialrichtung ist hierbei diejenige Richtung zu verstehen, in welcher die Abdeckung auf die Wartungsöffnung aufgesetzt wird. Unter radialer Richtung ist die dazu senkrechte Richtung zu verstehen. Die genannten Dichtungsausführungen sind konstruktiv und funktionell vorteilhaft.In one embodiment of the invention, the seal is circumferentially axially sealing or circumferentially radial sealing. Under axial direction is to be understood that direction in which the cover is placed on the maintenance opening. The radial direction is understood to mean the direction perpendicular thereto. The seal types mentioned are structurally and functionally advantageous.
In einer Weiterbildung der Erfindung weist die Dichtung einen Abstandshalterabschnitt auf, der die Abdeckung axial vom Armaturengrundkörper beabstandet. Damit lässt sich ein direkter Berührkontakt von Abdeckung und Armaturengrundkörper vermeiden bzw. ein definierter Spalt zwischen Abdeckung und Armaturengrundkörper bereitstellen.In a development of the invention, the seal has a spacer section which axially spaces the cover from the fitting main body. This makes it possible to avoid direct contact between the cover and the main body of the fitting or to provide a defined gap between the cover and the main body of the fitting.
In einer Weiterbildung der Erfindung sind die Trägerplatte und die Dichtung von einem thermoplastischen Mehrkomponenten-Bauteil gebildet, bei dem die Trägerplatte aus einem thermoplastischen Material besteht und die Dichtung aus einem an die Trägerplatte spritzgießtechnisch angespritzten thermoplastischen Elastomermaterial besteht. Diese Ausführung für die Trägerplatte und die Dichtung ist hinsichtlich Fertigungsaufwand vorteilhaft. Zudem wird dadurch ein sehr sicherer Halt der Dichtung an der Trägerplatte bereitgestellt.In a development of the invention, the carrier plate and the seal are formed by a thermoplastic multi-component component, in which the carrier plate consists of a thermoplastic material and the seal consists of a injection-molded onto the carrier plate thermoplastic elastomer material. This design for the carrier plate and the seal is in terms of manufacturing costs advantageous. In addition, this provides a very secure hold of the seal on the support plate.
In einer Weiterbildung der Erfindung beinhaltet die lösbare Verbindungsstruktur eine Schnappverbindung zwischen der Trägerplatte und dem Armaturengrundkörper, wobei die Schnappverbindung in alternativen Ausführungen selbstausrastend oder ausrastbar realisiert ist. Mit selbstausrastend ist hierbei gemeint, dass die Schnappverbindung sich von selbst löst, wenn die Abdeckung vom Armaturengrundkörper weggezogen wird. Mit ausrastbar ist gemeint, dass die Schnappverbindung durch eine entsprechende Ausrastbetätigung eines Benutzers ausgerastet werden muss, um die Abdeckung vom Armaturengrundkörper abnehmen zu können. Je nach Bedarf und Anwendungsfall kann die eine oder die andere Schnappverbindung zum Einsatz kommen.In a further development of the invention, the releasable connection structure includes a snap connection between the support plate and the fitting body, wherein the snap connection is realized in alternative embodiments selbstausrastend or disengaged. By Selbstausrastend this means that the snap connection dissolves by itself when the cover is pulled away from the fitting body. By disengageable is meant that the snap connection must be disengaged by a corresponding Ausrastbetätigung a user to remove the cover from the fitting body. Depending on requirements and application, one or the other snap connection can be used.
In einer alternativen Weiterbildung der Erfindung beinhaltet die lösbare Verbindungsstruktur eine Schnappverbindung zwischen der Dichtung und dem Armaturengrundkörper. Dazu beinhaltet die Schnappverbindung eine an der Dichtung ausgebildete Schnappwulst und eine am Armaturengrundkörper ausgebildete Schnappausnehmung. Damit kann die Dichtung vorteilhaft die entsprechende Verbindungsfunktion zusätzlich zu ihrer Abdichtfunktion übernehmen, was anderweitige Schnappverbindungsstrukturen an der Trägerplatte überflüssig machen kann.In an alternative development of the invention, the releasable connection structure includes a snap connection between the seal and the fitting body. For this purpose, the snap connection includes a snap bead formed on the seal and a snap recess formed on the fitting body. Thus, the seal can advantageously take over the corresponding connection function in addition to its sealing function, which can make other snap connection structures on the support plate superfluous.
In einer Weiterbildung der Erfindung besitzt die Deckplatte eine plane, rechteckige Form. Dies kann fertigungstechnische, handhabungstechnische und gestalterische Vorteile bieten.In a further development of the invention, the cover plate has a plane, rectangular shape. This can offer manufacturing, handling and design advantages.
In einer Weiterbildung der Erfindung sind der Zulaufteil und der Auslaufteil des Armaturengrundkörpers jeweils quaderförmig gebildet, wobei sie mit ihren Quaderhauptebenen einen Winkel zwischen 80° und 100° einschließen. Diese Gestaltung eignet sich insbesondere für sanitäre Wasserauslaufarmaturen, bei denen der Auslaufteil im Wesentlichen rechtwinklig vom Zulaufteil abführt.In one embodiment of the invention, the inlet part and the outlet part of the fitting body are each formed cuboid, wherein they include an angle between 80 ° and 100 ° with their cuboid main planes. This design is particularly suitable for sanitary water outlet fittings, in which the outlet part discharges substantially at right angles from the inlet part.
In einer Weiterbildung der Erfindung weist die Wasserauslaufarmatur eine im Armaturengrundkörper über die Wartungsöffnung zugänglich aufgenommene Auslaufbaugruppe auf, wobei die Auslaufbaugruppe eine Auslaufrohrleitung und ein an deren stromabwärtiges Ende angekoppeltes, strahlbildendes Wasseraustrittselement umfasst, das in einer unterseitigen Austrittsöffnung des Auslaufteils positioniert ist. Dadurch kann die Auslaufbaugruppe insgesamt über die Wartungsöffnung in den Armaturengrundkörper eingebracht und dort in gewünschter Weise positioniert werden. Die Auslaufbaugruppe enthält auch bereits das strahlbildende Wasseraustrittselement, so dass dieses nicht nachträglich z.B. von unten am Armaturengrundkörper oder an einer in diesem aufgenommenen Komponente angebracht werden muss. Bei dem strahlbildenden Wasseraustrittselement kann es sich z.B. um ein austrittsseitiges Strahlformer-, Strahlregler- bzw. Luftsprudlerelement handeln.In a further development of the invention, the water outlet fitting has an outlet assembly, which is accessible in the fitting body via the maintenance opening, wherein the outlet assembly has an outlet pipe and an Comprises downstream end coupled, jet-forming water outlet element, which is positioned in a lower-side outlet opening of the outlet part. As a result, the outlet assembly can be introduced in total via the maintenance opening in the fitting body and positioned there in the desired manner. The outlet assembly also already contains the jet-forming water outlet element, so that this does not have to be installed subsequently, for example, from below on the main body of the fitting or on a component accommodated therein. The jet-forming water outlet element may be, for example, an outlet-side beam former, jet regulator or aerator element.

Das Einsatzelement 6 kann insbesondere, wie gezeigt, als zylindrische Einsatzpatrone ausgeführt sein, an der das Partikelsieb 7 und/oder der Durchflussregler 8 einteilig angeformt oder als separat vorgefertigte Bauteile gehalten sind.In alternative embodiments, only one component is received in the fitting body of the two
Im gezeigten Ausführungsbeispiel ist im Armaturengrundkörper 1 zudem eine Auslaufbaugruppe 13 aufgenommen, die eine Auslaufrohrleitung 14 und ein an deren stromabwärtiges Ende angekoppeltes, strahlbildendes Wasseraustrittselement 15 umfasst. Das Wasseraustrittselement 15, bei dem es sich z.B. um einen Strahlregler bzw. Strahlformer herkömmlicher Art handeln kann, ist in einer unterseitigen Austrittsöffnung 16 des Armaturengrundkörpers 1 und speziell des Auslaufteils 3 positioniert. Die Auslaufrohrleitung 14 ist eintrittsseitig an die Ventileinheit 5 angekoppelt, z.B. an einen Mischwasserausgang derselben.In the exemplary embodiment shown, a
Im gezeigten Ausführungsbeispiel sind der Zulaufteil 2 und der Auslaufteil 3 jeweils quaderförmig gebildet, wobei sie mit ihren Quaderhauptebenen einen Winkel zwischen 80° und 100° einschließen, z.B. einen Winkel von ca. 90°. In alternativen Ausführungen ist der Zulaufteil 2 und/oder der Auslaufteil 3 von anderer Gestalt, z.B. mit einem ovalen oder kreisförmigen Querschnitt. Wenn die Auslaufarmatur an ihrem Einsatzort montiert ist, erstreckt sich der Zulaufteil 2 mit seiner Quaderhauptebene bzw. seiner Längsachse z.B. im Wesentlichen vertikal und der Auslaufteil 3 mit seiner Quaderhauptebene bzw. seiner Längsachse z.B. im Wesentlichen horizontal.In the illustrated embodiment, the
Die offene Oberseite des Auslaufabschnitts 3, d.h. die Wartungsöffnung 4, ist mit einer Abdeckung 17 verschlossen, die lösbar am Auslaufabschnitt 3 befestigt ist. Die Abdeckung 17 umfasst eine Trägerplatte 18, eine an der Trägerplatte 18 unterseitig umlaufende Dichtung 19 und eine auf der Trägerplatte 18 oberseitig angebrachte Deckplatte 20. Passend zur quaderförmigen Gestalt des Auslaufteils 3 besitzt die Deckplatte 20 in diesem Ausführungsbeispiel eine rechteckige und vorzugsweise plane Form. Gleiches gilt vorzugsweise für die Trägerplatte 18. Je nach Bedarf und Anwendungsfall ist die Deckplatte 20 lösbar oder unlösbar mit der Trägerplatte 18 verbunden. Im gezeigten Ausführungsbeispiel ist als Verbindungsmittel eine zweiseitig klebende Klebestreifenanordnung 21 mit einem oder mehreren Klebestreifen bzw. Klebepads vorgesehen.The open top of the
