Strahlregler insgesamt oder Einbauteile solcher Strahlregler müssen wegen Abnützung, Verschmutzung und/oder Verkalkung und auch aus hygienischen Gründen von Zeit zu Zeit ausgewechselt werden.Overall aerator or built-in parts of such aerators must be replaced from time to time because of wear, contamination and / or calcification and also for hygienic reasons.

Üblicherweise befinden sich Strahlregler in einem Gehäuse, das in eine Auslaufarmatur ein- und ausschraubbar ist, wobei an dem Strahlregler-Gehäuse Angriffsstellen für ein Werkzeug vorgesehen sind. Das Auswechseln des Strahlreglers erfordert somit Werkzeug und gewisse Kenntnisse des Bedienpersonals. In Einrichtungen, wo eine Vielzahl solcher Strahlregler installiert sind, wie zum Beispiel Hotels, Kliniken und WC-Anlagen, ist somit die Wartung insgesamt relativ aufwendig.Usually, jet regulators are located in a housing which can be screwed into and out of an outlet fitting, wherein attack points for a tool are provided on the jet regulator housing. The replacement of the jet regulator thus requires tools and some knowledge of the operating personnel. In facilities where a variety of such aerators are installed, such as hotels, clinics and toilet facilities, so the maintenance is relatively expensive overall.

Aus der DE 38 17 270 A1 ist bereits eine sanitäre Auslaufarmatur mit einem Strahlregler bekannt, der ein Strahlregler-Gehäuse hat, das mittels einer axialen Einschubbewegung in ein Mundstück einsetzbar ist. An dem, verschiedene Einbauteile in sich aufnehmenden Strahlregler-Gehäuse ist eine Halterung vorgesehen, die das Strahlregler-Gehäuse im Mundstück in Normalbetriebsstellung zu fixieren vermag und bei Überschreiten eines vorgegebenen Rückstaudruckes derart freigibt, dass der Strahlregler entweder aus dem Strahlregler-Gehäuse herausfällt oder aber in eine Auslösestellung gelangt, in der beispielsweise um den Strahlregler herum ein den Gesamtdurchtrittsquerschnitt vergrößernder Ringkanal gebildet ist. Die Halterung des vorbekannten Strahlreglers weist dazu als Federbügel ausgestaltete, radial bewegliche Vorsprünge auf, die an ihren freien Enden Rastrippen tragen, welche in eine umlaufende Ringnut im Strahlregler-Gehäuse eingreifen. Der vorbekannte Strahlregler lässt sich auch bei Rückstau empfindlichen Geräten, wie insbesondere Durchlauferhitzern einsetzen, die bei Überschreiten eines vorgegebenen Rückstaudruckes ansonsten zu Beschädigungen und Fehlfunktionen neigen. Eine einfachere und schnellere Montage und Demontage ist mit dem vorbekahnten Strahlregler demgegenüber nicht bezweckt.From the DE 38 17 270 A1 already a sanitary outlet fitting with a jet regulator is known, which has a jet regulator housing which is insertable by means of an axial insertion movement into a mouthpiece. At the, different mounting parts in receiving jet regulator housing is provided a holder which is capable of fixing the jet regulator housing in the mouthpiece in normal operating position and releases when a predetermined back pressure is exceeded so that the jet regulator either falls out of the jet regulator housing or in reaches a release position in which, for example, around the jet regulator around a total passage cross-section enlarging annular channel is formed. The holder of the previously known jet regulator has configured as a spring clip, radially movable projections on their carry free ends locking ribs, which engage in a circumferential annular groove in the jet regulator housing. The previously known jet regulator can also be used in backflow-sensitive devices, such as in particular instantaneous water heaters, which otherwise tend to damage and malfunction when a predetermined back pressure is exceeded. A simpler and faster assembly and disassembly is not intended with the vorbekahnten jet regulator on the other hand.

Aufgabe der vorliegenden Erfindung ist es, eine sanitäre Auslaufarmatur der eingangs erwähnten Art zu schaffen, mit einer alternativen Form zu der aus der DE 38 17 270 A1 bekannten Federzunge, insbesondere bei welcher besser vermieden werden kann, dass diese vor der Montage abbrechen kann.Object of the present invention is to provide a sanitary outlet fitting of the type mentioned, with an alternative form to that of the DE 38 17 270 A1 known spring tongue, in particular in which it can be better avoided that this can break off before mounting.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der sanitären Auslaufarmatur der eingangs erwähnten Art in den kennzeichnenden Merkmalen des Patentanspruchs 1.The achievement of this object is the sanitary outlet fitting of the type mentioned in the characterizing features of claim 1.

Der im Wasserauslauf der erfindungsgemäßen Auslaufarmatur verwendete Strahlregler lässt sich mit einem bloßen Fingerdruck einfach und bequem montieren.The jet regulator used in the water outlet of the outlet fitting according to the invention can be easily and conveniently mounted with a mere finger pressure.

Bei der erfindungsgemäßen Auslaufarmatur kann das Auswechseln des Strahlreglers auf einfache Weise von Hilfskräften, beispielsweise Reinigungspersonal, vorgenommen werden, die lediglich über Kenntnisse von der einfachen Handhabung verfügen. Nach der Entnahme des Strahlreglers kann dieser insgesamt oder dessen Einbauteile gewechselt werden.In the outlet fitting according to the invention, the replacement of the jet regulator can be carried out in a simple manner by auxiliary staff, for example cleaning personnel, who only have knowledge of the simple handling. After removal of the jet regulator this total or its built-in parts can be changed.

Weiterhin ist vorteilhaft, dass ein Austauschprozess des Strahlreglers deutlich schneller vonstatten geht als bisher.Furthermore, it is advantageous that an exchange process of the jet regulator is much faster than before.

Dies ist besonders dort wichtig, wo aus hygienischen Gründen ein häufiger, gegebenenfalls auch täglicher Wechsel des Strahlreglers vorgeschrieben ist, um eine Desinfektionsmaßnahme, wie beispielsweise eine Autoklavendesinfektion, durchzuführen.This is especially important where for hygienic reasons a frequent, possibly even daily change of the jet regulator is prescribed to perform a disinfection measure, such as an autoclave disinfection.

Eine besonders sichere Festlegung des Strahlreglers im Wasserauslauf wird erreicht, wenn der wenigstens eine, radial bewegliche Vorsprung zum Eingreifen in eine, im Wasserauslauf befindliche Vertiefung ausgebildet ist.A particularly secure determination of the jet regulator in the water outlet is achieved if the at least one, radially movable projection for engaging in a recess located in the water outlet is formed.

Der erfindungsgemäß ausgestaltete Strahlregler kann in den Wasserauslauf einer speziell an ihn angepassten Auslaufarmatur eingesetzt werden. Soll der erfindungsgemäß ausgestaltete Strahlregler demgegenüber auch in Verbindung mit handelsüblichen Auslaufarmaturen verwendet werden, kann es zweckmäßig sein, wenn der Wasserauslauf als ein, mit einer Auslaufarmatur vorzugsweise lösbar verbindbares Adaptermundstück oder Mundstück ausgebildet ist.The inventively designed jet regulator can be used in the water outlet of a specially adapted to him outlet fitting. If the jet regulator designed according to the invention is also used in conjunction with commercially available outlet fittings, it may be expedient for the water outlet to be designed as an adapter mouthpiece or mouthpiece which is preferably detachably connectable to an outlet fitting.

Gegebenenfalls kann das Adaptermundstück mit einer inneren Ausnehmung als Teil der Rasthalterung zur Aufnahme des Strahlregler-Gehäuses vorgesehen sein, wobei das Adaptermundstück mit einer Auslaufarmatur verbindbar ist.
Zweckmäßig ist es dabei, wenn das Adaptermundstück ein Anschlussgewinde zum verbinden mit der Auslaufarmatur aufweist.Optionally, the adapter mouthpiece may be provided with an inner recess as part of the detent holder for receiving the jet regulator housing, wherein the adapter mouthpiece is connectable to an outlet fitting.
It is useful if the adapter mouthpiece has a connecting thread for connection to the outlet fitting.

Der erfindungsgemäß vorgesehene Strahlregler kann damit sowohl direkt in einer entsprechend ausgebildeten Auslaufarmatur als auch mit Hilfe des Adaptermundstücks an traditionellen Armaturen mit Einschraubgewinde für einen üblichen Einschraub-Strahlregler eingesetzt werden. Dazu wird das Adaptermundstück einmalig an der Auslaufarmatur angeschraubt. Somit ist auch ein problemloses Nachrüsten bestehender Armaturen und eine Umstellung auf den erfindungsgemäß vorgesehenen Strahlregler möglich.The jet regulator provided according to the invention can therefore be used both directly in a suitably designed outlet fitting and with the aid of the adapter mouthpiece on traditional fittings with a screw thread for a conventional screw-in jet regulator. For this purpose, the adapter mouthpiece is screwed once to the outlet fitting. Thus, a problem-free retrofitting of existing fittings and a conversion to the inventively provided Jet regulator possible.

Zweckmäßigerweise sind dabei zwei diametral gegenüberliegende Federelemente mit Rastvorsprüngen vorgesehen, die eine ausreichende Halterung des Strahlreglers in einem Mundstück ergeben.
Dabei weisen das Strahlregler-Gehäuse und die Federelemente mit den Rastvorsprüngen abströmseitig einen flanschartigen, nach außen weisenden Griffansatz auf.Appropriately, two diametrically opposed spring elements are provided with locking projections, which provide sufficient support of the jet regulator in a mouthpiece.
In this case, the jet regulator housing and the spring elements with the latching projections downstream a flange-like, outwardly facing handle approach.

Dieser Strahlregler kann ebenfalls ohne Werkzeug montiert und demontiert werden. Zur Montage wird der Strahlregler zum Beispiel mit der flachen Hand in das Armaturen-Mundstück gedrückt. Zur Demontage werden die beiden seitlichen, nach innen elastisch nachgiebigen Rastelemente mit zwei Fingern an den Griffansätzen zusammengedrückt und der Strahlregler kann dann herausgezogen werden.This jet regulator can also be mounted and dismantled without tools. For assembly, the jet regulator is pressed, for example, with the palm of your hand into the fitting mouthpiece. For disassembly, the two lateral, inwardly elastically yielding locking elements are pressed together with two fingers on the handle lugs and the jet regulator can then be pulled out.

Nach einer Ausgestaltung der Erfindung weisen die Rastelemente Rastflächen auf, die schräg mit Hinterschnitt zur Querschnittsebene des Strahlreglers verlaufen.According to one embodiment of the invention, the latching elements on latching surfaces which extend obliquely with an undercut to the cross-sectional plane of the jet regulator.

Dadurch ist eine Verriegelung gebildet, die vor dem Entnehmen des Strahlreglers gelöst werden muss. Dazu wird der Strahlregler zunächst etwas nach innen axial eingeschoben und dadurch die Verriegelung gelöst. Die Rastelemente werden dann an den Griffansätzen zusammengedrückt, so dass sie außer Eingriff kommen und der Strahlregler entnommen werden kann.As a result, a lock is formed, which must be solved before removing the jet regulator. For this purpose, the jet regulator is first inserted slightly axially inwards, thereby releasing the lock. The locking elements are then compressed at the handle lugs so that they disengage and the jet regulator can be removed.

Zusätzliche Ausgestaltungen der Erfindung sind in den weiteren Unteransprüchen aufgeführt. Nachstehend sind Ausführungsbeispiele der Erfindung anhand der Zeichnungen näher beschrieben.Additional embodiments of the invention are set forth in the further subclaims.

Die Figuren 1 bis 8 zeigen eine Ausführungsform eines erfindungsgemäßen Strahlreglers 1b, dessen Strahlregler-Gehäuse 3b, 3c Federelemente 9a mit nach außen vorstehenden Rastvorsprüngen 10a zum direkten Eingreifen in eine Ringnut 13a des Mundstücks 2a aufweist. In diesem Fall bilden die Rastvorsprünge 10a gleichzeitig die Verriegelungselemente, so dass ein als separates Teil ausgebildetes verriegelungselement hier nicht erforderlich ist.The FIGS. 1 to 8 show an embodiment of a jet regulator according to the invention 1b, the jet regulator housing 3b, 3c spring elements 9a having outwardly projecting locking projections 10a for direct engagement in an annular groove 13a of the mouthpiece 2a. In this case, the locking projections 10a simultaneously form the locking elements, so that a trained as a separate part locking element is not required here.

Im Ausführungsbeispiel sind zwei diametral gegenüberliegende Federelemente 9a mit Rastvorsprüngen 10a vorgesehen. Diese Federelemente 9a mit den Rastvorsprüngen 10a sind mit ihrer der Ausströmseite 7 des Strahlreglers abgewandten Seite einstückig mit der Strahlregler-Gehäusewand verbunden und durch seitliche Schlitze von der angrenzenden Gehäusewand getrennt. Abströmseitig schließt sich an das Strahlregler-Gehäuse 3b ein flanschartiger, nach außen weisender Griffansatz 24a an. Im Bereich der Federelemente 9a mit den Rastvorsprüngen 10a ist der Griffansatz 24a durch die seitlichen Schlitze 45 aufgetrennt, so dass der mit dem Federelement 9a verbundene Teil des Griffansatzes 24a zum radialen Einfedern der Rastvorsprünge 10a mit den Fingern eingedrückt werden kann. Der übrige Bereich des Griffansatzes 24a, der mit dem Gehäuse 3b verbunden ist, dient auch zum Herausziehen des Strahlreglers 1b aus einem Mundstück 2a (vgl. Fig.3 und 4).In the exemplary embodiment, two diametrically opposite spring elements 9a are provided with latching projections 10a. These spring elements 9a with the latching projections 10a are integrally connected with their side facing away from the outflow 7 of the jet regulator side with the jet regulator housing wall and separated by lateral slots of the adjacent housing wall. Downstream of the jet regulator housing 3b connects to a flange-like, outwardly facing handle lug 24a. In the area of the spring elements 9a with the latching projections 10a, the handle projection 24a is separated by the lateral slots 45, so that the part of the handle attachment 24a connected to the spring element 9a can be pressed with the fingers for radial compression of the latching projections 10a. The remaining area of the handle attachment 24a, which is connected to the housing 3b, also serves to pull out the jet regulator 1b from a mouthpiece 2a (see FIG. 3 and 4 ).

Besonders in Fig.2 ist gut erkennbar, dass die Rastvorsprünge 10a in die Gehäuseaußenseite übergehende Auflaufschrägen 31 aufweisen. Beim Einsetzen des Strahlreglers 1b in ein Mundstück treffen diese Auflaufschrägen 31 auf den Innenrand des Mundstücks und werden beim weiteren Einsetzen in dieses radial nach innen eingefedert, bis die Rastvorsprünge 10a in die umlaufende Ringnut 13a radial nach außen einrasten. Die Rastvorsprünge 10a sind mit ihren Rastflächen 32 beabstandet zum abströmseitigen Rand 33 des Gehäuses 3b beziehungsweise zu dem Griffansatz 24a angeordnet, so dass das Gehäuse 3b mit seinem Griffansatz 24a unten noch so weit hervorschaut, dass es zum Entriegeln und Herausziehen ergriffen werden kann.Especially in Fig.2 is clearly visible that the locking projections have 10a in the outside of the housing transitional bevels 31. When inserting the jet regulator 1b in a mouthpiece meet this run-on slopes 31 on the inner edge of the mouthpiece and are rebound during further insertion into this radially inward until the locking projections 10a engage in the circumferential annular groove 13a radially outward. The latching projections 10a are arranged with their latching surfaces 32 spaced from the downstream edge 33 of the housing 3b or to the handle extension 24a, so that the housing 3b with his handle approach 24a down still so far out that it can be taken to unlock and pull out.

Die Funktion eines Verriegelungselementes übernehmen im vorliegenden Ausführungsbeispiel die mit einem Hinterschnitt versehenen Rastflächen 32, die in entsprechend gegengeformte Einformungen der Ringnut 13a eingreifen. Der Hinterschnitt ist so ausgebildet, dass zum Entriegeln des Strahlreglers 1b dieser zunächst etwas angehoben und dabei in das Mundstück etwas eingeschoben werden muss, bis der Hinterschnitt frei ist, so dass dann die Rastvorsprünge 10a durch radiales Eindrücken der damit verbundenen Abschnitt des Griffansatzes 24a entriegelt werden können. Anschließend kann der Strahlregler 1b nach unten aus dem Mundstück herausgenommen werden.The function of a locking element take over in the present Embodiment which provided with an undercut locking surfaces 32 which engage in corresponding counter-shaped recesses of the annular groove 13a. The undercut is designed so that for unlocking the beam regulator 1b this first raised slightly while something has to be inserted into the mouthpiece until the undercut is free, so that then the locking projections 10a are unlocked by radial impressions of the associated portion of the handle extension 24a can. Subsequently, the jet regulator 1b can be taken down from the mouthpiece.

In der Detailansicht gemäß Fig.4a ist noch eine nach innen vorstehende Positioniernocke 36 für einen einzusetzenden Strahlzerleger 4 erkennbar. Dadurch kann der Strahlzerleger 4 lagerichtig in das Gehäuse 3b eingesetzt werden.In the detail view according to 4a is still an inwardly projecting Positioniernocke 36 for a beam splitter 4 to be used recognizable. As a result, the jet splitter 4 can be inserted in the correct position in the housing 3b.

Gemäß Fig.1 bis 4 erfolgt die Abdichtung des Strahlreglers 1b gegenüber dem Mundstück 2a mittels einer Radialdichtung mit einem O-Ringnutflansch 35, die sich an dem Strahlzerleger 4 befindet. Der O-Ringnutflansch 35 mit dem darin befindlichen Dichtelement liegt zuströmseitig auf einer ringförmigen Stirnseite 34 des Strahlregler-Gehäuses 3b auf. Zweckmäßig ist es dabei, wenn die Stirnseite 34 mit dem Strahlzerleger 4 verbunden, vorzugsweise ultraschallverschweißt ist.According to Fig.1 to 4 the jet regulator 1b is sealed off from the mouthpiece 2a by means of a radial seal with an O-ring groove flange 35 which is located on the jet separator 4. The O-ring groove flange 35 with the sealing element located therein is located on the inflow side on an annular end face 34 of the jet regulator housing 3b. It is useful if the end face 34 connected to the beam splitter 4, preferably ultrasonically welded.

Die Fig.5 bis 8 zeigen eine weitere Ausführungsvariante, bei der das Strahlregler-Gehäuse 3c an seinem zuströmseitigen Ende außenseitig eine Ringnut 46 mit darin befindlicher Ringdichtung 47 zur Radialabdichtung gegenüber einem Mundstück 2a aufweist. Das Gehäuse 3c ist durchgehend als Hülse mit einer innenseitig glatten, geschlossenen Oberfläche ausgebildet. In dieses hülsenförmige Strahlregler-Gehäuse 3c ist der Strahlzerleger 4 eingesetzt. Die Verbindung und Abdichtung zwischen dem Strahlregler-Gehäuse 3c und dem eingesetzten Strahlzerleger 4 kann durch ein Fügeverfahren, zum Beispiel durch Ultraschallschweißen erfolgen. Dies erfolgt im Bereich einer Auflageschulter 48 und der zuströmseitigen Stirnseite des Strahlregler-Gehäuses 3c. Auch bei dieser Ausführungsform sind die Rast- und Verriegelungselemente gegenüber dem Wasserstrom abgeschottet, so dass eine Verkalkungsanfälligkeit wesentlich reduziert ist.The Fig.5 to 8 show a further embodiment variant in which the jet regulator housing 3c at its inflow end has on the outside an annular groove 46 with annular seal 47 located therein for radial sealing with respect to a mouthpiece 2a. The housing 3c is continuously formed as a sleeve with an inside smooth, closed surface. In this sleeve-shaped jet regulator housing 3c of the jet splitter 4 is used. The connection and sealing between the jet regulator housing 3c and the used beam splitter 4 can be done by a joining process, for example by ultrasonic welding. This takes place in the region of a support shoulder 48 and the inflow-side end face of the jet regulator housing 3c. Also in this embodiment, the latching and locking elements are sealed off from the water flow, so that a calcification susceptibility is substantially reduced.

In Fig.7 ist gut erkennbar, dass die Wand des Strahlregler-Gehäuses 3c im Bereich der Federelemente 9a eine nach innen geschlossene Ausnehmung 42 mit einer zum Federelement 9a zumindest um den Einfederweg des Federelements beabetandete Außenseite 43 aufweist. Einerseits ist dadurch genügend Einfederplatz für die Federelemente 9a mit ihren Rastvorsprüngen 10a vorhanden und andererseits ist auch in diesem Bereich eine nach innen geschlossene Wandung vorhanden.In Figure 7 is clearly visible that the wall of the jet regulator housing 3c has an inwardly closed recess 42 in the region of the spring elements 9a with an outer side 43 which is at least arranged around the spring-loaded spring element 9a. On the one hand, this provides enough spring-insertion space for the spring elements 9a with their latching projections 10a, and on the other hand, an inwardly closed wall is also present in this area.
