Description

Die Erfindung betrifft ein Auslaufelement für eine Sanitärarmatur, mit einem Anschlussteil, das an der Sanitärarmatur abströmseitig lösbar befestigbar ist, sowie mit einem Auslaufteil, welches einen den Armaturenauslauf bildenden. Flüssigkeitsauslass hat, in welchem Flüssigkeitsauslass eine sanitäre Funktionseinheit einsetzbar ist, wobei das Anschlussteil und das Auslaufteil gelenkig und/oder drehbar miteinander verbunden sind.The invention relates to an outlet element for a sanitary fitting, with a connection part, which is releasably attachable to the sanitary fitting on the outflow side, as well as with an outlet part, which forms a the valve outlet. Liquid outlet has, in which liquid outlet a sanitary functional unit can be used, wherein the connecting part and the outlet part are articulated and / or rotatably connected to each other.

Man kennt bereits Auslaufelemente der eingangs erwähnten Art, bei denen das mit der Sanitärarmatur verbundene Anschlussteil und das den Armaturenauslauf bildende Auslaufteil über ein Kugelgelenk drehbar und schwenkbar miteinander verbunden sind. Ein derart gelenkiges Auslaufelement, dessen Auslaufteil zum Ausrichten des Flüssigkeitsstrahls derart gedreht und verschwenkt werden kann, vermag eine Küchenbrause zu ersetzen.Outlet elements of the type mentioned above are already known in which the connection part connected to the sanitary fitting and the outlet part forming the fitting outlet are connected to one another in a rotatable and pivotable manner via a ball joint. Such a hinged outlet element, whose outlet part can be rotated and pivoted for aligning the liquid jet in such a way, can replace a kitchen shower.

Der an das Kugelgelenk angrenzende Abschnitt des Auslaufteiles dieser vorbekannten Auslaufelemente weist ein Außengewinde auf, auf das das Innengewinde eines den Flüssigkeitsauslass bildenden Auslaufmundstücks aufschraubbar ist. In das Auslaufmundstück ist eine als Einsetzpatrone ausgestaltete sanitäre Funktionseinheit einsetzbar. Das zum Einsetzen der Einsetzpatrone erforderliche Verschrauben des Auslaufmundstücks mit dem dem Kugelgelenk zugewandten Abschnitt des Auslaufteiles gibt einen im wesentlichen runden Außenquerschnitt des Auslaufelementes vor. Die Außenkontur der vorbekannten Auslaufelemente kann somit im Widerspruch zum ästhetischen Anspruch und Eindruck stehen, der insbesondere mit besonders auffällig und formschön gestalteten Sanitärarmaturen angestrebt wird. Dabei wird der ästhetische Eindruck noch zusätzlich durch den deutlich sichtbaren Spalt getrübt, der sich zwischen dem dem Kugelgelenk zugewandten Abschnitt des Auslaufteiles einerseits und dem Auslaufmundstück andererseits bildet.The adjacent to the ball joint portion of the outlet part of these known outlet elements has an external thread on which the internal thread of the liquid outlet forming outlet nozzle is screwed. In the outlet mouthpiece designed as Einsetzpatrone sanitary functional unit can be used. The required for inserting the cartridge screwing the outlet nozzle with the ball joint facing portion of the outlet part is a substantially round outer cross-section of the outlet element. The outer contour of the known outlet elements may thus be in contradiction to the aesthetic claim and impression, in particular with particularly striking and shapely designed sanitary fittings is sought. In this case, the aesthetic impression is additionally clouded by the clearly visible gap which forms between the part of the outlet part facing the ball joint on the one hand and the outlet mouthpiece on the other.

Aus der US-A-2 971 701 ist bereits ein Auslaufelement mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt, das mit einem Anschlussteil an einer Sanitärarmatur lösbar befestigbar ist und dass ein Auslaufteil aufweist, welches einen den Armaturenauslauf bildenden Flüssigkeitsauslass hat, wobei das Anschlussteil und das Auslaufteil über ein Kugelgelenk gelenkig und drehbar miteinander verbunden sind. In dem den Flüssigkeitsauslass bildenden Auslaufteil sind mehrere Einsetzteile mit Abstand voneinander eingefügt, die im Zusammenwirken miteinander den Wasserstrahl belüften und formen sollen. Um diese Einsetzteile im Inneren des hülsenförmigen Auslaufteiles unterbringen zu können, weist das Auslaufteil des aus US-A-2 971 701 vorbekannten Auslaufelementes zwei hülsenförmige Gehäuseteile auf, die über eine Schraubverbindung lösbar miteinander verbunden sind. Durch Lösen und Trennen dieser Gehäuseteile kann das Hülseninnere des Auslaufteiles geöffnet und die Einsetzteile von der Zuströmseite aus in das untere auslaufseitige Gehäuseteil eingesetzt werden. Die zwischen den Gehäuseteilen vorgesehene Schraubverbindung und die horizontale Trennung dieser Gehäuseteile bedingt jedoch einen von außen sichtbaren Spalt, der unschön und optisch störend wirkt. Auch müssen die eine sanitäre Funktionseinheit bildenden Einsetzteile einzeln und nacheinander in das auslaufseitige Gehäuseteil eingesetzt werden. Damit diese Einsetzteile im auslaufseitigen Gehäuseteil gehalten sind, verjüngt sich das untere Gehäuseteil zunehmend zu seinem Flüssigkeitsauslass hin.From the US-A-2,971,701 an outlet element with the features of the preamble of claim 1 is already known, which is detachably fastened with a connection part to a sanitary fitting and that has an outlet part, which has a drain outlet forming liquid outlet, wherein the connection part and the outlet part via a ball joint hinged and rotatable connected to each other. In the outlet part forming the liquid outlet a plurality of insert parts are inserted at a distance from each other, which in cooperation with each other to aerate and shape the water jet. In order to accommodate these inserts inside the sleeve-shaped outlet part, has the outlet part of US-A-2,971,701 previously known spout element on two sleeve-shaped housing parts, which are detachably connected to each other via a screw connection. By loosening and separating these housing parts, the sleeve interior of the outlet part can be opened and the insert parts can be inserted from the inflow side into the lower outlet-side housing part. However, the provided between the housing parts screw and the horizontal separation of these housing parts requires a visible from the outside gap that looks ugly and visually disturbing. Also, the sanitary functional unit forming inserts must be used individually and sequentially in the outlet side housing part. In order for these insert parts are held in the outlet side housing part, the lower housing part increasingly tapers towards its liquid outlet.

Es besteht daher insbesondere die Aufgabe, ein Auslaufelement der eingangs erwähnten Art zu schaffen, das sich bei aller Funktionalität durch einen hohen gestalterischen Spielraum auszeichnet.There is therefore in particular the task of creating an outlet element of the type mentioned above, which is characterized by a high creative freedom in all functionality.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Auslaufelement der eingangs erwähnten Art insbesondere darin, dass die sanitäre Funktionseinheit als Einsetzpatrone ausgestaltet ist, die von der Mündungsseite aus in den Flüssigkeitsauslass einsetzbar und darin lösbar gehalten ist, und dass der Flüssigkeitsauslass des Auslaufteils im lichten Querschnitt an die Einsetzpatrone angepasst ist.The achievement of this object is in the outlet element of the type mentioned in particular that the sanitary functional unit is designed as Einsetzpatrone which is inserted from the mouth side into the liquid outlet and releasably held therein, and that the liquid outlet of the outlet part in the clear cross-section the cartridge is adapted.

Die als Einsetzpatrone ausgestaltete Funktionseinheit ist von der Mündungsseite aus in den Flüssigkeitsauslass einsetzbar und im Auslaufteil des Auslaufelementes lösbar gehalten. Zur Aufnahme dieser Einsetzpatrone ist der Flüssigkeitsauslass des Auslaufteils im lichten Querschnitt an die Einsetzpatrone angepasst. Auf ein mit zusätzlichen, nicht unerheblichen Kosten verbundenes Mundstück kann somit verzichtet werden. Da das Anschrauben eines solchen Auslaufmundstückes verzichtbar ist, ist die Herstellung des erfindungsgemäßen Auslaufelementes deutlich vereinfacht. Da auf ein Mundstück verzichtet werden kann, werden die auch bei Verwendung herkömmlicher Mundstücke üblichen Spalte zwischen dem Auslaufmundstück einerseits und dem dem Kugelgelenk zugewandten Abschnitt des Auslaufteiles andererseits vermieden, die ansonsten optisch störend wirken und hohen hygienischen Ansprüchen entgegenstehen würden. DieThe functional unit designed as an insert cartridge can be inserted into the liquid outlet from the outlet side and is detachably held in the outlet part of the outlet element. To accommodate this insert cartridge, the liquid outlet of the outlet part is adapted in the clear cross section of the Einsetzpatrone. On an associated with additional, not inconsiderable costs mouthpiece can thus be dispensed with. Since the screwing of such an outlet mouthpiece is dispensable, the production of the outlet element according to the invention is significantly simplified. Since it is possible to dispense with a mouthpiece, the usual gap between the outlet mouthpiece on the one hand and the ball joint facing portion of the outlet part on the other hand avoided when using conventional mouthpieces, which would otherwise be visually disturbing and would be contrary to high hygienic standards. The

sanitäre Funktionseinheit ist lösbar im Flüssigkeitsauslass des Auslaufteils gehalten und kann somit für Servicearbeiten, wie zum Beispiel zum Entfernen von Schmutz oder zum Entkalken, auch vom ungeübten Anwender einfach gelöst und entnommen werden. Durch den Verzicht auf ein Auslaufmundstück wird auch der gestalterische Spielraum bei der Entwicklung des erfindungsgemäßen Auslaufelementes erhöht, so dass beispielsweise auch Auslaufelemente mit einem runden oder vieleckigen Außenumfang möglich sind, die sich in ihrer Drehstellung bequem an die Sanitärarmatur und deren Außenkontur anpassen lassen.sanitary functional unit is detachably held in the liquid outlet of the outlet part and can thus be easily detached and removed even for inexperienced users for service work, for example for removing dirt or for descaling. By dispensing with an outlet mouthpiece and the creative scope in the development of the outlet element according to the invention is increased, so that, for example, outlet elements with a round or polygonal outer periphery are possible, which can be easily adapted in its rotational position to the sanitary fitting and its outer contour.

Um das erfindungsgemäße Auslaufelement mit geringem Aufwand sicher und fest an der Sanitärarmatur befestigen zu können, ist es vorteilhaft, wenn das Anschlussteil ein Außengewinde trägt, das in ein Innengewinde an der Sanitärarmatur einschraubbar ist.In order to safely and firmly attach the outlet element according to the invention with little effort to the sanitary fitting, it is advantageous if the connection part carries an external thread which can be screwed into an internal thread on the sanitary fitting.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht vor, dass die Ringzone im Verbindungsbereich zwischen Anschlussteil und Sanitärarmatur mittels zumindest einer Ringdichtung radial abgedichtet ist. Da diese Ringdichtung radial wirkt, ist für die Befestigung des Auslaufelementes an der Sanitärarmatur kein axialer Anschlag notwendig, daher ist diese erfindungsgemäße Ausführungsform auch für dünnwandige Rohre der Sanitärarmatur geeignet und das andernfalls erforderliche und mit hohem Aufwand verbundene umlöten eines Gewindenippels ist entbehrlich.A preferred development according to the invention provides that the annular zone is radially sealed in the connecting region between the connection part and the sanitary fitting by means of at least one annular seal. Since this ring seal acts radially, no axial stop is necessary for the attachment of the outlet element to the sanitary fitting, therefore, this embodiment of the invention is also suitable for thin-walled pipes of the sanitary fitting and the otherwise required and associated with high costs umlen a threaded nipple is unnecessary.

Damit der durch die Sanitärarmatur fließende Flüssigkeitsstrahl am Armaturenauslauf zu einem homogen-weichen und nichtspritzenden Gesamtstrahl geformt werden kann, ist es vorteilhaft, wenn die Einsetzpatrone zumindest einen Strahlregler aufweist.In order for the liquid jet flowing through the sanitary fitting to be able to be shaped at the fitting outlet into a homogeneous-soft and non-spraying overall jet, it is advantageous if the insertion cartridge has at least one jet regulator.

Da das Anschlussteil einerseits und das Auslaufteil andererseits relativ zueinander verdreht werden können, lässt sich die Außenkontur des erfindungsgemäßen Auslaufelementes leicht und bequem an die Außenkontur der Sanitärarmatur anpassen. Möglich ist daher, dass das Auslaufteil einen runden oder eckigen, insbesondere einen viereckigen Außenumfang hat. Weist das Auslaufteil einen viereckigen Außenumfang auf, können die Außenseiten des Auslaufteiles parallel zu den benachbarten Außenseiten einer entsprechend gestalteten der Sanitärarmatur ausgerichtet werden.Since the connection part on the one hand and the outlet part on the other hand can be rotated relative to each other, the outer contour of the outlet element according to the invention can be easily and conveniently adapted to the outer contour of the sanitary fitting. It is therefore possible that the outlet part has a round or square, in particular a square outer periphery. If the outlet part has a quadrangular outer circumference, the outer sides of the outlet part can be aligned parallel to the adjacent outer sides of a correspondingly designed sanitary fitting.

Besonders vorteilhaft ist es, wenn die Einsetzpatrone mit zumindest dem überwiegenden Teilbereich ihrer Längserstreckung, vorzugsweise vollständig mit ihrer gesamten Längserstreckung im Flüssigkeitsauslass angeordnet ist. Ist die Einsetzpatrone vollständig mit ihrer gesamten Längserstreckung im Flüssigkeitsauslass angeordnet, kann sie versteckt, d.h. von außen praktisch unsichtbar und manipulationssicher im Flüssigkeitsauslass untergebracht werden. Von dort ist die Einsetzpatrone beispielsweise mit Hilfe eines Kronen- oder Gabelschlüssels oder eines anderen Entnahmewerkzeuges bei Bedarf wieder zu lösen.It is particularly advantageous if the insert cartridge is arranged with at least the predominant portion of its longitudinal extent, preferably completely with its entire longitudinal extent in the liquid outlet. If the insert cartridge is completely located with its entire length in the liquid outlet, it can be hidden, i. From the outside virtually invisible and tamper-proof in the liquid outlet can be accommodated. From there, the insertion cartridge, for example, with the help of a crown or fork wrench or other removal tool when needed to solve again.

Die Einsetzpatrone kann unmittelbar, ohne zusätzliche Adapter, im Flüssigkeitsauslass gehalten sein. Eine andere Ausführungsform gemäß der Erfindung sieht vor, dass die Einsetzpatrone mittels eines vorzugsweise hülsenförmigen Zwischenhalters im Flüssigkeitsauslass gehalten ist.The insert cartridge can be held directly in the liquid outlet without additional adapters. Another embodiment according to the invention provides that the insert cartridge is held by means of a preferably sleeve-shaped intermediate holder in the liquid outlet.

Um die Montage der Einsetzpatrone im Flüssigkeitsauslass zu erleichtern und um dort die Lage der Einsetzpatrone festzulegen, ist es zweckmäßig, wenn die Einsetzpatrone oder der Zwischenhalter bis zu einem Einsetzanschlag in den Flüssigkeitsauslass des Auslaufteiles einsetzbar ist.In order to facilitate the installation of the insert cartridge in the liquid outlet and to determine there the position of the insert cartridge, it is advantageous if the insert cartridge or the intermediate holder can be used until an insertion stop in the liquid outlet of the outlet part.

Dabei ist es möglich, dass der von der Mündungsseite aus in den Flüssigkeitsauslass einsetzbare Zwischenhalter lösbar oder unlösbar im Flüssigkeitsauslass gehalten ist.It is possible that the insertable from the outlet side into the liquid outlet intermediate holder is releasably or permanently held in the liquid outlet.

Vorteilhaft ist es, wenn der Zwischenhalter im Flüssigkeitsauslass mittels einer Kleb-, Klemm-, Rast- und/oder Schraubverbindung und/oder durch Verpressen, Verkrallen oder Verkeilen gehalten ist. Dabei ist es vorteilhaft, wenn der Zwischenhalter gegenüber der inneren Umfangswand des Flüssigkeitsauslasses vorzugsweise umlaufend abgedichtet ist. Das Eindichten des Zwischenhalters im Flüssigkeitsauslass des Auslaufteiles kann mittels zusätzlicher Dichtungen wie z.B. O-Ring oder Flachdichtung, mittels an den Zwischenhalter angeformter Dichtungen oder mit Hilfe der Verbindungsmittel, beispielsweise durch die beim Verkleben des Zwischenhalters verwendeten Klebemittel, erfolgen.It is advantageous if the intermediate holder is held in the liquid outlet by means of an adhesive, clamping, latching and / or screw connection and / or by pressing, clawing or wedging. It is advantageous if the intermediate holder is preferably circumferentially sealed with respect to the inner peripheral wall of the liquid outlet. The sealing of the intermediate holder in the liquid outlet of the outlet part can be achieved by means of additional seals, such as e.g. O-ring or gasket, by means of molded to the intermediate holder seals or by means of the connecting means, for example by the adhesive used in the bonding of the intermediate holder, take place.

Vorteilhaft ist es, wenn die Einsetzpatrone im Flüssigkeitsauslass oder im Zwischenhalter mittels einer Klemm-, Rast- oder Schraubverbindung gehalten ist. So kann die Einsetzpatrone beispielsweise durch eine ein- oder mehrgängige Schraubverbindung oder durch Verschnappung und somit durch solche lösbaren Verbindungen in der Auslaufarmatur oder dem Zwischenhalter gehalten sein, die bei Bedarf eine einfache und rasche Montage und Demontage der Funktionseinheit erlauben.It is advantageous if the insert cartridge is held in the liquid outlet or in the intermediate holder by means of a clamping, latching or screw connection. Thus, the cartridge can be kept, for example, by a single or multi-start screw or by snapping and thus by such releasable connections in the outlet fitting or the intermediate holder, which allow a simple and rapid assembly and disassembly of the functional unit if necessary.

Zweckmäßig ist es, wenn die Einsetzpatrone gegenüber dem Zwischenhalter oder der inneren Umfangswand des Flüssigkeitsauslasses abgedichtet ist. Eine solche Abdichtung der Funktionseinheit gegenüber dem Zwischenhalter oder der inneren Umfangswand des Flüssigkeitsauslasses kann beispielsweise über einen O-Dichtring, eine Flachdichtung oder über andere bekannte Dichtungen erfolgen.It is expedient if the insert cartridge is sealed against the intermediate holder or the inner peripheral wall of the liquid outlet. Such a sealing of the functional unit with respect to the intermediate holder or the inner peripheral wall the Flüssigkeitsauslasses can be done for example via an O-ring, a gasket or other known seals.

Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass zur Abdichtung zwischen Einsetzpatrone beziehungsweise Zwischenhalter einerseits und dem Flüssigkeitsauslass andererseits zumindest eine Ringdichtung, vorzugsweise wenigstens ein O-Ring, vorgesehen ist.In this case, a preferred embodiment according to the invention provides that for sealing between insert cartridge or intermediate holder on the one hand and the liquid outlet on the other hand, at least one ring seal, preferably at least one O-ring is provided.

Nach einem weiterbildenden Vorschlag gemäß der Erfindung ist vorgesehen, dass die Einsetzpatrone oder der Zwischenhalter ein Außengewinde trägt, das in ein Innengewinde im Flüssigkeitsauslass des Auslaufteiles einschraubbar ist, und dass das Außengewinde und das Innengewinde derart bemessen und angeordnet sind, dass die Gewinde beim Einschrauben der Einsetzpatrone beziehungsweise des Zwischenhalters einander in einer Relativposition von Flüssigkeitsauslass einerseits und Einsetzpatrone beziehungsweise Zwischenhalter andererseits fassen, in welcher der an der Einsetzpatrone oder dem Zwischenhalter außenumfangsseitig vorgesehene O-Ring oder dergleichen Ringdichtung die den Flüssigkeitsauslass begrenzende innere Umfangswandung noch nicht reibschlüssig berührt. Durch die Anordnung der Ringdichtung, welche die Einsetzpatrone radial im Armaturengehäuse abdichtet, kann bei der Montage und bei der Demontage ein deutlicher Vorteil genutzt werden: Beim Montieren hat man deutlich mehr Gefühl für das Finden der Gewinde, da die Ringdichtung erst dann radial verpresst wird, wenn sich das Gewinde bereits gefunden hat. Durch die Verpressung der Ringdichtung wird viel Reibung erzeugt, die das Gefühl für die Montage sonst deutlich erschweren würde. Bei der Demontage hat die gewählte Anordnung der Ringdichtung den Vorteil, dass die Einsetzpatrone mit Hilfe des Einsetz- und Entnahmewerkzeugs aus der Schraubverbindung mit dem Flüssigkeitsauslass des Auslaufteiles herausgedreht wird. Solange sich die Ringdichtung noch im verpressten Zustand befindet, erfolgt eine axiale Zwangsbewegung durch das Gewinde. Erst wenn die Ringdichtung die den Flüssigkeitsauslass begrenzende Umfangswandung verlassen hat, kommt das Gewinde auch aus dem Eingriff. Dies hat den entscheidenden Vorteil, dass man die als versteckte Einsetzpatrone ausgestaltete und gegebenenfalls mit einem Zwischenhalter montierte Funktionseinheit vollständig durch Drehbewegung aus der Armatur entfernen kann und dazu nicht wegen Reibungseinflüssen zusätzlich ziehen muß beziehungsweise die Unterstützung des Wasserdrucks benötigt.According to a further development proposal according to the invention it is provided that the insert cartridge or the intermediate holder carries an external thread which can be screwed into an internal thread in the liquid outlet of the outlet part, and that the external thread and the internal thread are dimensioned and arranged such that the thread when screwing the Insertion cartridge or the intermediate holder grip each other in a relative position of the liquid outlet on the one hand and insert cartridge or intermediate holder on the other hand, in which the outer peripheral side provided on the Einsetzpatrone or the intermediate holder O-ring or the like ring seal the not yet frictionally touches the liquid outlet inner circumferential wall. The arrangement of the ring seal which seals the cartridge radially in the valve body, a significant advantage can be used during assembly and disassembly: When mounting one has significantly more feeling for finding the thread, since the ring seal is then pressed radially, if the thread has already been found. By pressing the ring seal much friction is generated, which would otherwise make the feeling of mounting otherwise difficult. When disassembling the selected arrangement of the ring seal has the advantage that the insert cartridge with the help of the insertion and removal tool the screw connection with the liquid outlet of the outlet part is unscrewed. As long as the ring seal is still in the compressed state, there is an axial forced movement through the thread. Only when the ring seal has left the circumferential wall delimiting the liquid outlet does the thread come out of engagement. This has the decisive advantage that you can completely remove the designed as a hidden cartridge insert and optionally mounted with an intermediate holder functional unit by rotating movement of the valve and not have to pull because of friction in addition needs or support the water pressure needed.

Möglich ist aber auch, dass an die Einsetzpatrone zumindest eine umlaufende Dichtung einstückig angeformt ist, wobei die Einsetzpatrone im lichten Bereich nicht nur als Mehrkomponenten-Spritzgußteil, sondern insbesondere auch als Einkomponenten-Spritzgußteil ausgestaltet sein kann.It is also possible that at least one circumferential seal is integrally formed on the insert cartridge, wherein the insert cartridge in the clear area can be configured not only as a multi-component injection molding, but in particular as a one-component injection molding.

Eine besonders vorteilhafte Weiterbildung gemäß der Erfindung von eigener schutzwürdiger Bedeutung sieht vor, dass die Einsetzpatrone und/oder der Zwischenhalter mit zumindest einer zwischen der Einsetzpatrone beziehungsweise dem Zwischenhalter einerseits und dem Auslaufteil andererseits umlaufend abdichtenden Dichtung einstückig verbunden ist. Die an der Einsetzpatrone und/oder dem Zwischenhalter vorgesehene und einstückig angeformte Dichtung verhindert Kriech- bzw. Leckströme der durch das Auslaufelement durchströmenden Flüssigkeit u.a. zwischen der Einsetzpatrone beziehungsweise dem Zwischenhalter einerseits und dem Flüssigkeitsauslass andererseits.A particularly advantageous development according to the invention of its own worth-worthy significance provides that the insert cartridge and / or the intermediate holder is integrally connected to at least one circumferentially sealing between the insert cartridge and the intermediate holder on the one hand and the outlet part. The on the cartridge and / or the intermediate holder provided and integrally molded seal prevents creepage or leakage currents flowing through the outlet element fluid u.a. between the insert cartridge or the intermediate holder on the one hand and the liquid outlet on the other.

Vorteilhaft kann es sein, wenn der zuströmseitige Stirnrandbereich der Einsetzpatrone und/oder des Zwischenhalter als Dichtprofil ausgestaltet ist. Eine derartige Ausgestaltung kann auch mit einem vergleichsweise breiten Stirnrand ausgestaltet sein, ohne dass der lichte äußere Querschnitt dadurch zu sehr eingeschränkt wird. Dieser vergleichsweise breite Stirnrand an der Einsetzpatrone und/oder dem Zwischenhalter kann anschließend sehr gut zur Ausgestaltung auch eines vergleichsweise komplexen Dichtprofils herangezogen werden.It can be advantageous if the inflow-side end edge region the insertion cartridge and / or the intermediate holder is designed as a sealing profile. Such a configuration can also be designed with a comparatively wide end edge, without the clear outer cross-section being thereby restricted too much. This comparatively wide end edge on the insertion cartridge and / or the intermediate holder can then be used very well for the design of a comparatively complex sealing profile.

Bei der Ausgestaltung des Dichtprofils ist es zweckmäßig, wenn das Dichtprofil zumindest eine Flächen- und/oder eine Lippendichtung aufweist. Diese Formen des Dichtprofils können zusammen mit dem Gegenanschlag im Flüssigkeitsauslass eine wirksame Abdichtung bewirken, wenn das Dichtprofil den Gegenanschlag beaufschlagt und dabei eine Linien- und/oder Flächenpressung auf das Dichtprofil ausgeübt wird.In the embodiment of the sealing profile, it is expedient if the sealing profile has at least one surface and / or lip seal. These forms of the sealing profile can effect an effective seal together with the counter-stop in the liquid outlet when the sealing profile acts on the counter-stop and a line and / or surface pressure is thereby exerted on the sealing profile.

Um eine übermäßige Verformung des Dichtprofils zu verhindern, ist es zweckmäßig, wenn die Einsetzpatrone und/oder der Zwischenhalter zuströmseitig einen Einsetz-Anschlag aufweisen, der in Gebrauchsstellung eine Verformung des Dichtprofils begrenzt. Anderenfalls könnte das Dichtprofil beschädigt oder übermäßig verformt werden, was zu einer Undichtigkeit im Bereich zwischen Einsetzpatrone beziehungsweise Zwischenhalter und der den Flüssigkeitsauslass begrenzenden Umfangswandung und somit zu entsprechenden Kriechströmen führen könnte.In order to prevent excessive deformation of the sealing profile, it is expedient if the insert cartridge and / or the intermediate holder on the inflow side have an insertion stop which limits a deformation of the sealing profile in the position of use. Otherwise, the sealing profile could be damaged or excessively deformed, which could lead to leakage in the area between insert cartridge or intermediate holder and the circumferential wall bounding the liquid outlet and thus to corresponding leakage currents.

Bei der Gestaltung des Dichtprofils ist es vorteilhaft, wenn das Dichtprofil zumindest eine Dichtung mit einer DichtprofilBasis hat, die als Einsetz-Anschlag ausgestaltet ist. Das Dichtprofil kann dabei auf der oberen Begrenzungsfläche der Dichtprofilbasis angeordnet sein. Der Einsetz-Anschlag kann dazu dienen, beim Befestigen der Einsetz-Patrone oder des Zwischenhalters an der Armatur beispielsweise über eine Schraubverbindung die Einschraubtiefe zu begrenzen. Geschieht das Einschrauben ohne Werkzeug manuell, so kann der Einsetzanschlag ein Festigkeitsgefühl der Schraubverbindung vermitteln, in dem die Beaufschlagung des Gegenanschlags im Flüssigkeitsauslass durch den Einsetz-Anschlag spürbar ist.In the design of the sealing profile, it is advantageous if the sealing profile has at least one seal with a sealing profile base, which is designed as an insertion stop. The sealing profile can be arranged on the upper boundary surface of the sealing profile base. The insertion stop may serve to secure the insertion cartridge or cartridge when mounting Intermediate holder on the valve, for example, via a screw to limit the screwing. Happens screwing without tools manually, so the insertion stop can give a feeling of strength of the screw, in which the application of the counter-attack in the liquid outlet is noticeable by the insertion stop.

Um eine möglichst große Fläche des lichten Querschnitts der Einsetzpatrone beziehungsweise des Zwischenhalters nutzen zu können beziehungsweise den lichten Querschnitt nicht unnötig zu verengen, ist es zweckmäßig, wenn das Dichtprofil und gegebenenfalls sein Einsetz-Anschlag mit einem den lichten Querschnitt begrenzenden Stirnrandbereich des Flüssigkeitsauslasses zusammenwirkt, welcher der Einsetzpatrone und/oder dem Zwischenhalter gleichzeitig als Gegenanschlag dient.In order to use as large an area as possible of the clear cross section of the insertable cartridge or of the intermediate holder or to unnecessarily narrow the clear cross section, it is expedient if the sealing profile and optionally its insertion stop cooperate with a front edge region of the liquid outlet which delimits the clear cross section the insert cartridge and / or the intermediate holder simultaneously serves as a counter-stop.

Dabei ist es für die Funktion des Einsetz-Anschlags besonders vorteilhaft, wenn der Einsetz-Anschlag dem Dichtprofil in radialer Richtung benachbart angeordnet ist. Somit kann der Einsetz-Anschlag genau die Kräfte auffangen, die das Dichtprofil eventuell beschädigen könnten. Außerdem kann damit eine platzsparende Anordnung des Einsetz-Anschlags und des Dichtprofils und ein entsprechend großer lichter Querschnitt der Einsetzpatrone erreicht werden.It is particularly advantageous for the function of the insertion stop when the insertion stop is arranged adjacent to the sealing profile in the radial direction. Thus, the insertion stop can accurately absorb the forces that could possibly damage the sealing profile. In addition, thus a space-saving arrangement of the insertion stop and the sealing profile and a correspondingly large clear cross section of the Einsetzpatrone be achieved.

Eine einfache und trotzdem wirksam abdichtende Ausgestaltung des Dichtprofils besteht darin, dass das Dichtprofil zumindest eine ringförmig umlaufende Dichtlippe hat. Diese Dichtlippe kann entweder elastisch und flexibel gestaltet sein und sich dadurch beim Befestigen der Einsetzpatrone und/oder des Zwischenhalters dem Gegenanschlag in der Auslaufarmatur anpassen, oder die Dichtlippe ist so gestaltet, dass eine Verformung nur schwer möglich ist, so dass die Dichtlippe beim Befestigen nur durch eine Flächenpressung durch den Gegenanschlag der Auslaufarmatur abdichtet. Diese beiden Möglichkeiten können bei mehreren Dichtlippen auf unterschiedliche Weise kombiniert werden.A simple yet effective sealing design of the sealing profile is that the sealing profile has at least one annular circumferential sealing lip. This sealing lip can be designed either elastic and flexible and thereby adapt to the counter stop in the outlet fitting when attaching the insertable cartridge and / or the intermediate holder, or the sealing lip is designed so that deformation is difficult, so that the sealing lip when mounting only seals by a surface pressure through the counter-stop of the outlet fitting. These two possibilities can be combined with different sealing lips in different ways.

Eine besonders vorteilhafte Ausgestaltung des Dichtprofils sieht vor, dass das Dichtprofil wenigstens zwei ringförmig umlaufende Dichtlippen hat, die mit zunehmendem, auf den Strahlregler einwirkenden Einsetzdruck nacheinander wirksam werden. Diese abgestufte Ausgestaltung des Dichtprofils kann bewirken, dass bei Ausfall einer Dichtlippe die benachbarten Dichtlippen des Dichtprofils wirksam werden. Außerdem kann durch Nachziehen des im Auslaufteil verschraubten Bauteils, d.h. der Einsetzpatrone beziehungsweise des Zwischenhalters, ein Einsetzdruck ausgeübt werden, derart, dass zumindest auch weitere Dichtungen des Dichtprofils wirksam werden können.A particularly advantageous embodiment of the sealing profile provides that the sealing profile has at least two annular circumferential sealing lips, which are effective successively with increasing, acting on the jet regulator insertion pressure. This stepped configuration of the sealing profile can cause the adjacent sealing lips of the sealing profile to become effective if one sealing lip fails. In addition, by tightening the screwed in the outlet part component, i. the Einsetzpatrone or the intermediate holder, a Einsetzdruck be exercised, such that at least other seals of the sealing profile can be effective.

Eine weitere Ausgestaltung mit ringförmig umlaufenden und nacheinander wirksam werdenden Dichtlippen sieht vor, dass diese Dichtlippen unterschiedliche Höhen aufweisen. Dabei ist es nach längerem Gebrauch der Einsetzpatrone und/oder des Zwischenhalters möglich, die Dichtwirkung durch Nachziehen des im Flüssigkeitsauslass verschraubten Bauteils langzeitig aufrecht zu erhalten. Ist die höchste Dichtlippe bereits etwas beschädigt oder abgenutzt oder unflexibel geworden, kann die in der Höhe nächstkommende Dichtlippe die Dichtwirkung nach dem Festziehen wieder erreichen. Außerdem können eventuell kleine Unebenheiten des Gegenanschlags im Flüssigkeitsauslass ausgeglichen werden. Dabei kann es vorteilhaft sein, wenn die Dichtlippen gestufte Höhen aufweisen und wenn die höchste Dichtlippe die innerste oder die äußerste Dichtung des Dichtprofils bildet.A further embodiment with annular circumferential and consecutively effective sealing lips provides that these sealing lips have different heights. It is possible after prolonged use of the cartridge and / or the intermediate holder to maintain the sealing effect by tightening the bolted in the liquid outlet component long-term. If the highest sealing lip has already become slightly damaged or worn or inflexible, the sealing lip closest to the height can reach the sealing effect again after tightening. In addition, any small bumps of the counter-stop in the liquid outlet can be compensated. It may be advantageous if the sealing lips have stepped heights and if the highest sealing lip forms the innermost or the outermost seal of the sealing profile.

Möglich ist es, dass das die Dichtung aufweisende Bauteil der Einsetzpatrone und/oder des Zwischenhalters als Mehrkomponenten-Spritzgußteil hergestellt ist und dass dieses Bauteil im Bereich der wenigstens einen Dichtung aus einem flexiblen und/oder elastischen Material besteht. Für das einfache Recycling der die Einsetzpatrone und/oder den Zwischenhalter bildenden Materialien ist es jedoch zweckmäßig, wenn die Dichtung und das mit ihr einstückig verbundene Bauteil der Einsetzpatrone und/oder des Zwischenhalters aus demselben, vorzugsweise lebensmittelechten Material hergestellt sind. Dabei können der Herstellungsaufwand vereinfacht und die Werkzeugkosten für ein eventuell erforderliches Spritzgusswerkzeug vergleichsweise gering gehalten werden.It is possible for the component of the inserting cartridge and / or the intermediate holder having the seal to be produced as a multi-component injection-molded part and for this component to consist of a flexible and / or elastic material in the region of the at least one seal. For the simple recycling of the insert cartridge and / or the intermediate holder forming materials, however, it is expedient if the seal and the component of the insert cartridge and / or the intermediate holder integral therewith are made of the same, preferably food-safe material. In this case, the production costs can be simplified and the tool costs for a possibly required injection molding tool can be kept comparatively low.

In den Figuren 1 bis 4 ist ein Auslaufelement 1 für eine Sanitärarmatur dargestellt, das ein an der Sanitärarmatur abströmseitig lösbar befestigbares Anschlussteil 2 sowie ein Auslaufteil 3 aufweist, welches Auslaufteil 3 einen den Armaturenauslauf bildenden Flüssigkeitsauslass 4 hat.FIGS. 1 to 4 show an outlet element 1 for a sanitary fitting, which has a connection part 2 releasably attachable to the sanitary fitting and an outlet part 3, which outlet part 3 has a liquid outlet 4 forming the valve outlet.

Das Anschlussteil 2 und das Auslaufteil 3 des Auslaufelements 1 sind über ein Kugelgelenk 5 gelenkig miteinander verbunden. Aus einem Vergleich der Figuren 1 und 2 wird deutlich, dass das Kugelgelenk 5 ein Verdrehen und Verschwenken von Anschlussteil 2 und Auslaufteil 3 relativ zueinander erlaubt. Durch Verdrehen und verschwenken des über das Anschlussteil 2 an der Sanitärarmatur gehaltenen Auslaufteiles 3 kann der aus dem Auslaufelement 1 ausströmende Wasserstrahl bei Bedarf derart ausgerichtet werden, dass beispielsweise eine Küchenbrause entbehrlich ist. Gleichzeitig aber kann auch das in seinem Außenquerschnitt hier viereckige Auslaufteil aus ästhetischen Gründen derart verdreht werden, dass zwei zueinander parallele Außenseiten des Auslaufteiles 3 parallel zu den benachbarten Längsseiten einer eventuell ebenfalls eckig ausgestaltete Sanitärarmatur verlaufen.The connection part 2 and the outlet part 3 of the outlet element. 1 are connected via a ball joint 5 hinged together. From a comparison of Figures 1 and 2 it is clear that the ball joint 5 allows a rotation and pivoting of the connection part 2 and outlet part 3 relative to each other. By turning and pivoting of the connection part 2 held on the sanitary fitting outlet part 3 of the outflowing element 1 effluent water jet can be aligned if necessary, such that, for example, a kitchen shower is unnecessary. At the same time but also in its outer cross section here square outlet part can be rotated for aesthetic reasons such that two mutually parallel outer sides of the outlet part 3 extend parallel to the adjacent longitudinal sides of a possibly also angularly configured sanitary fitting.

In die den Flüssigkeitsauslass 4 des Auslaufteiles 3 bildende Innenhöhlung ist eine als Einsetzpatrone 6 ausgestaltete sanitäre Funktionseinheit einsetzbar. Aus den Figuren 1 bis 4 ist erkennbar, dass der Flüssigkeitsauslass 4 des Auslaufteiles 3 im lichten Querschnitt an die Einsetzpatrone 6 angepasst ist, und dass die Einsetzpatrone 6 von der Mündungsseite in den Flüssigkeitsauslass 4 einsetzbar und darin lösbar gehalten ist.In the liquid outlet 4 of the outlet part 3 forming inner cavity designed as an insert cartridge 6 sanitary functional unit can be used. It can be seen from FIGS. 1 to 4 that the liquid outlet 4 of the outlet part 3 is adapted to the insertion cartridge 6 in the clear cross section, and that the insertion cartridge 6 can be inserted from the outlet side into the liquid outlet 4 and held detachably therein.

Da die Einsetzpatrone von der Mündungsseite des Auslaufelementes 1 aus in den Flüssigkeitsauslass 4 einsetzbar ist, kann auf ein ansonsten übliches Auslaufmundstück verzichtet werden, das einem unrunden Querschnitt entgegenstehen und einen Spalt zwischen Auslaufmundstück und den übrigen Bestandteilen des Auslaufteiles 3 erfordern würde.Since the insert cartridge can be inserted from the outlet side of the outlet element 1 in the liquid outlet 4, can be dispensed with an otherwise usual outlet nozzle, which oppose a non-circular cross-section and would require a gap between the outlet nozzle and the other components of the outlet part 3.

Die Einsetzpatrone 6 ist vollständig mit ihrer gesamten Längserstreckung im Flüssigkeitsauslass 4 angeordnet und hier mittels einer Schraubverbindung im Flüssigkeitsauslass 4 gehalten. Die Einsetzpatrone 6 weist dazu in einem abströmseitigen Teilbereich ihres Patronengehäuses ein Außengewinde 7 auf, das in ein Innengewinde 8 im Flüssigkeitsauslass 4 einschraubbar ist. Zur Abdichtung der Ringzone zwischen der Einsetzpatrone 6 einerseits und der den Flüssigkeitsauslass 4 begrenzenden Innenwandung andererseits ist ein O-Ring 9 vorgesehen. Der O-Ring 9 ist hier in Einschraubrichtung derart hinter dem Außengewinde 7 angeordnet, dass die Gewinde 7, 8 beim Einschrauben der Einsetzpatrone 6 einander in einer Relativposition fassen, in welcher der O-Ring 9 die den Flüssigkeitsauslass 4 begrenzende Innenwandung noch nicht reibschlüssig berührt. Durch diese Anordnung des O-Rings 9, der die Einsetzpatrone 6 radial im Auslassteil 3 abdichtet, kann bei der Montage und bei der Demontage ein deutlicher Vorteil genutzt werden: Beim Montieren hat man deutlich mehr Gefühl für das Finden der Gewinde 7,8, da der O-Ring 9 erst dann radial verpresst wird, wenn sich die Gewinde 7, 8 bereits gefunden haben. Durch die Verpressung des O-Ringes 9 wird viel Reibung erzeugt, die das Gefühl für die Montage sonst deutlich erschweren würde. Bei der Demontage hat die gewählte Anordnung des O-Rings 9 den Vorteil, dass die Einsetzpatrone 6 mit Hilfe eines Einsetz- und Entnahmewerkzeugs aus der Schraubverbindung mit dem Auslaufteil herausgedreht wird. Solange sich diese Ringdichtung 9 noch in verpresstem Zustand befindet, erfolgt eine axiale Zwangsbewegung durch das Gewinde 7, 8. Erst wenn die Ringdichtung 9 das Auslaufteil 3 in axialer Richtung verlassen hat, kommen die Gewinde 7, 8 auch aus dem Eingriff. Dies hat den entscheidenden Vorteil, dass man die als versteckte Einsetzpatrone 6 ausgestaltete und gegebenenfalls auch mit einem Zwischenhalter montierte Funktionseinheit 6 vollständig durch Drehbewegung aus dem Auslaufteil 3 des Auslaufelements 1 entfernen kann und dazu nicht wegen Reibungseinflüssen zusätzlich axial ziehen muss beziehungsweise die Unterstützung des Wasserdrucks benötigt.The inserting cartridge 6 is arranged completely with its entire longitudinal extent in the liquid outlet 4 and here by means of a screw connection in the liquid outlet 4 held. For this purpose, the insert cartridge 6 has, in a downstream partial region of its cartridge housing, an external thread 7 which can be screwed into an internal thread 8 in the liquid outlet 4. For sealing the annular zone between the Einsetzpatrone 6 on the one hand and the liquid outlet 4 limiting inner wall on the other hand, an O-ring 9 is provided. The O-ring 9 is arranged here in the screwing behind the external thread 7, that the threads 7, 8 when screwing the Einsetzpatrone 6 hold each other in a relative position in which the O-ring 9, the liquid outlet 4 limiting inner wall is not frictionally contacted , By this arrangement of the O-ring 9, which seals the insert cartridge 6 radially in the outlet part 3, a clear advantage can be used during assembly and disassembly: When mounting one has significantly more feeling for finding the thread 7.8, since the O-ring 9 is then pressed radially only when the threads 7, 8 have already found. By compressing the O-ring 9 a lot of friction is generated, which would otherwise make the feeling of mounting otherwise difficult. When disassembling the selected arrangement of the O-ring 9 has the advantage that the Einsetzpatrone 6 is unscrewed by means of an insertion and removal tool from the screw with the outlet part. As long as this ring seal 9 is still in the compressed state, there is an axial forced movement through the thread 7, 8. Only when the ring seal 9 has left the outlet part 3 in the axial direction, the threads 7, 8 also come out of engagement. This has the decisive advantage that you can remove the installed as a cartridge cartridge 6 and possibly also with an intermediate holder mounted functional unit 6 completely by rotational movement of the outlet part 3 of the outlet element 1 and not because of friction must additionally pull axially or the support of the water pressure needed.

Insbesondere in den Figuren 1 bis 3 ist gut zu erkennen, dass das Patronengehäuse der Einsetzpatrone 6 eine konturierte Abström-Stirnseite hat, die als Werkzeugangriffsfläche für ein Einsetzwerkzeug ausgestaltet ist. Dabei weist die Abström-Stirnseite der hier dargestellten Einsetzpatrone 6 eine aus stirnrandseitigen Vorsprüngen 10 und Vertiefungen 11 gebildete Konturierung auf, derart, daß die Vertiefungen 11 einer im Auslaufteil 3 gehaltenen Einsetzpatrone 6 als Werkzeugangriffsfläche für die Vorsprünge 10 eines als Einsetzwerkzeug verwendbaren anderen Patronengehäuses dienen.In particular, in Figures 1 to 3 can be clearly seen that the cartridge housing of the insert cartridge 6 has a contoured outflow end face, which is designed as a tool engagement surface for an insertion tool. In this case, the outflow end face of Einsetzpatrone 6 shown here on a front edge projections 10 and recesses 11 formed contouring, such that the wells 11 are held in the outlet part 3 Einsetzpatrone 6 as a tool engagement surface for the projections 10 of a usable as an insertion tool other cartridge housing.

In Figur 3 ist erkennbar, dass das Anschlussteil 2 in seinem der Sanitärarmatur zugewandten zuströmseitigen Teilbereich einen Gewindeflansch 12 mit einem Außengewinde 13 hat, welches Außengewinde 13 in ein Innengewinde am abströmseitigen Endbereich der Sanitärarmatur einschraubbar ist. Auf dem die Durchflussöffnung begrenzenden zuströmseitigen Stirnrandbereich des Gewindeflansches 12 ist eine Flachdichtung oder Ringdichtung 14 vorgesehen, der in Haltestellung des Anschlussteiles 2 den abströmseitigen Stirnrandbereich der Sanitärarmatur dichtend beaufschlagt.In Figure 3 it can be seen that the connection part 2 has in its sanitary fitting facing inflow side portion a threaded flange 12 with an external thread 13, which external thread 13 can be screwed into an internal thread at the downstream end of the sanitary fitting. On the inflow-side end edge region of the threaded flange 12 delimiting the flow opening, a flat seal or ring seal 14 is provided, which in the holding position of the connection part 2 sealingly urges the outflow-side end edge region of the sanitary fitting.

Die als Einsetzpatrone 6 ausgestaltete Funktionseinheit ist hier als Strahlregler ausgebildet, der ein zuströmseitiges Vorsatzsieb 15 und einen abströmseitigen Strömungsgleichrichter 16 mit wabenförmig ausgestalteten Durchflusslöchern hat.The functional unit configured as insert cartridge 6 is designed here as a jet regulator, which has an inflow-side attachment screen 15 and a downstream-side flow rectifier 16 with honeycomb-shaped flow-through holes.

In den Figuren 5 bis 7 ist ein Auslaufelement 1' dargestellt, das mit dem in den Figuren 1 bis 4 gezeigten Auslaufelement 1 im wesentlichen baugleich ist. Das Auslaufelement 1' hat jedoch ein Auslaufteil 3 mit einem im wesentlichen runden Außenquerschnitt. Darüber hinaus ist der am Gewindeflansch 12 des Anschlussteiles 2 vorgesehene O-Ring und als Ringdichtung 14 wirkende in einer am Außenumfang des Gewindeflansches 12 angeordneten Ringnut gehalten. Diese, den O-Ring 14 tragende Ringnut ist - ähnlich wie der O-Ring 9 relativ zum Außengewinde 7 - hinter dem Außengewinde 13 angeordnet und dichtet den Gewindeflansch 12 radial gegenüber der den Mündungsbereich der Sanitärarmatur 17 begrenzenden Innenwandung ab. Durch die vergleichbare Ausgestaltung der Außengewinde 7, 13 einerseits und der Ringdichtungen 9, 14 andererseits lässt sich die Einsetzpatrone 6 auch bequem aus dem Auslaufteil 3 entnehmen, um anschließend - nach Entfernen des Auslaufelementes 1' - direkt mündungsseitig in die Sanitärarmatur 17 eingeschraubt zu werden, wie dies in Figur 8 veranschaulicht ist. Ebenso ist es möglich, die Einsetzpatrone 6 noch nachträglich um ein beispielsweise mit Kugelgelenk versehenes Auslaufelement 1' zu ergänzen.FIGS. 5 to 7 show an outlet element 1 ', which is essentially identical to the outlet element 1 shown in FIGS. 1 to 4. However, the outlet element 1 'has an outlet part 3 with a substantially round External cross-section. In addition, the provided on the threaded flange 12 of the connecting part 2 O-ring and acting as a ring seal 14 is held in a arranged on the outer circumference of the threaded flange 12 annular groove. This, the O-ring 14-bearing annular groove is - similar to the O-ring 9 relative to the external thread 7 - arranged behind the external thread 13 and seals the threaded flange 12 radially from the mouth region of the sanitary fitting 17 limiting inner wall. Due to the comparable design of the external threads 7, 13 on the one hand and the ring seals 9, 14 on the other hand, the insert cartridge 6 can also be conveniently removed from the outlet part 3, to subsequently - after removal of the outlet element 1 '- directly muzzle side be screwed into the sanitary fitting 17, as illustrated in FIG. It is also possible to supplement the insert cartridge 6 later by an example provided with ball joint outlet element 1 '.

Die hier dargestellten Auslaufelemente 1, 1' lassen sich ohne ein Auslaufmundstück und somit ohne eine störende axiale Trennung zwischen einem Auslaufmundstück und den übrigen Bestandteilen des Auslaufteiles herstellen, was einen ästhetischen Effekt und einen Hygienevorteil bietet. Zudem können im Gegensatz zu vorbekannten Konstruktionen gestalterisch neue Formen realisiert werden, wie beispielsweise die in den Figuren 1 bis 4 dargestellte durchgängig eckige Struktur, die bisher aufgrund der axialen Trennung zwischen Auslaufmundstück einerseits und den übrigen Bestandteilen des Auslaufteiles andererseits nur sehr schwer möglich war, weil ansonsten eckige Teile gegeneinander auszurichten wären, was erhöhte Erschwernisse an die erforderlichen Ringdichtungen mit sich bringt. Das Kugelgelenk 5, welches das Anschlussteil 2 und das Auslaufteil 3 der Auslaufelemente 1, 1' miteinander verbindet, ergibt auch im Zusammenwirken mit den derzeit sehr weit verbreiteten eckigen Armaturen ein harmonisches Gesamterscheinungsbild, da im Gegensatz zu vorbekannten Konstruktionen auch das Auslaufteil 3 in seinem Außenquerschnitt eckig gestaltet werden kann. Durch die Verwendung des Kugelgelenks 5 kann das Auslaufteil 3 mit den Kanten der Sanitärarmatur ausgerichtet werden, obwohl die Befestigung des Auslaufelementes 1, 1' an der Sanitärarmatur über ein klassisches Gewinde erfolgt, dessen Lage sich in der Endposition nicht im voraus definieren lässt.The outlet elements 1, 1 'shown here can be produced without an outlet nozzle and thus without any disruptive axial separation between an outlet nozzle and the other components of the outlet part, which offers an aesthetic effect and a hygiene advantage. In addition, in contrast to previously known constructions new shapes can be realized, such as the illustrated in Figures 1 to 4 consistently angular structure that was previously due to the axial separation between outlet nozzle on the one hand and the other components of the outlet part on the other hand very difficult, because otherwise angular parts would be aligned against each other, which brings increased difficulties to the required ring seals with it. The ball joint 5, which connects the connecting part 2 and the outlet part 3 of the outlet elements 1, 1 ', also results in the interaction with the currently very widespread angular fittings a harmonious overall appearance, since in contrast to previously known constructions, the outlet part 3 can be designed angular in its outer cross section. By using the ball joint 5, the outlet part 3 can be aligned with the edges of the sanitary fitting, although the attachment of the outlet element 1, 1 'takes place on the sanitary fitting via a classic thread whose position can not be defined in advance in the final position.

Möglich ist auch, den radial dichtenden O-Ring 14 des Auslaufelements 1' mit einem im Außenumfang eckigen Auslaufteil zu verwenden beziehungsweise die axial dichtende Ringdichtung 14 des Auslaufelements 1 mit einem im Außenumfang runden Auslaufteil 3 zu kombinieren.It is also possible to use the radially sealing O-ring 14 of the outlet element 1 'with an outlet part which is angular in the outer circumference or to combine the axially sealing annular seal 14 of the outlet element 1 with a discharge part 3 which is round in the outer circumference.
