Description

Die Erfindung betrifft eine sanitäre Auslaufarmatur mit einem Wasserauslauf, der eine Aufnahmeöffnung mit einem Innengewinde aufweist, mit einem hülsenförmigen Auslaufmundstück, das umfangsseitig ein in das Innengewinde der Aufnahmeöffnung lösbar einschraubbares Außengewinde trägt und mit einem Strahlregler oder dergleichen sanitären Einsetzteil, das im Hülseninneren des Auslaufmundstücks gehalten ist, wobei das Auslaufmundstück an seiner auslaufseitigen Stirnseite zumindest einen Schlitz, eine Profilierung oder dergleichen Werkzeugangriffsfläche trägt und wobei am auslaufseitigen Endbereich des Auslaufmundstücks ein das Auslaufmundstück umschließendes und als Vandalismussicherung dienendes Ringelement frei drehbar gelagert ist.The invention relates to a sanitary outlet fitting with a water outlet, which has a receiving opening with an internal thread, with a sleeve-shaped outlet mouthpiece, the peripherally carries a releasably screwed into the internal thread of the receiving opening male thread and with a jet regulator or the like sanitary insert, kept in the sleeve interior of the outlet mouthpiece is, wherein the outlet mouthpiece carries at least one slot, a profiling or the like Werkzeugangriffsfläche at its outlet side end and wherein the outlet side end portion of the outlet mouthpiece surrounding the outlet nozzle and serving as a vandalism ring element is freely rotatably mounted.

Die bei Auslaufarmaturen eingesetzten Strahlregler formen das ausströmende Wasser zu einem homogenen, perlend-weichen Wasserstrahl. Um an solchen sanitären Auslaufarmaturen einen solchen Strahlregler oder auch zumindest ein anderes sanitäres Einsetzteil befestigen zu können, sind bereits sanitäre Auslaufarmaturen mit einem Wasserauslauf bekannt, der eine Aufnahmeöffnung mit einem Innengewinde aufweist und ein hülsenförmiges Auslaufmundstück hat, das umfangsseitig ein in das Innengewinde der Aufnahmeöffnung lösbar einschraubbares Außengewinde trägt, wobei der Strahlregler oder dergleichen sanitäres Einsetzteil im Hülseninneren des Auslaufmundstücks gehalten ist. Häufig besteht jedoch das Problem, das die mittels eines hülsenförmigen Auslaufmundstücks an einer sanitären Auslaufarmatur gehaltenen Strahlregler oder dergleichen sanitären Einsetzteile, insbesondere wenn sie im öffentlichen Bereich, beispielsweise in Hotels, Gaststätten oder Sportanlagen eingesetzt sind, häufig von unbefugten Personen aus der Auslaufarmatur herausgeschraubt und gestohlen werden.The jet regulators used in outlet fittings form the outflowing water into a homogenous, soft water jet. To attach to such sanitary outlet fittings such a jet regulator or at least another sanitary insert, already sanitary outlet fittings with a water outlet are known, which has a receiving opening with an internal thread and a sleeve-shaped outlet nozzle, the circumferentially one in the internal thread of the receiving opening solvable carries screwed external thread, wherein the jet regulator or the like sanitary insert is held in the sleeve interior of the outlet nozzle. Frequently, however, there is the problem that held by means of a sleeve-shaped outlet mouthpiece on a sanitary outlet fitting jet regulator or the like sanitary fittings, in particular when they are used in the public sector, for example in hotels, restaurants or sports facilities, are often unscrewed and stolen by unauthorized persons from the outlet fitting.

Um einem derartigen Diebstahl vorzubeugen, sind sanitäre Auslaufarmaturen der eingangs genannten Art bekannt, deren Auslaufmundstück an seiner auslaufseitigen Stirnseite einen Schlitz, eine Profilierung oder dergleichen Werkzeugangriffsfläche trägt, wobei am auslaufseitigen Endbereich des Auslaufmundstücks ein das Auslaufmundstück umschließendes und als Vandalismussicherung dienendes Ringelement frei drehbar gelagert ist. Somit kann das Auslaufmundstück und das darin befindliche sanitäre Einsetzteil nicht von unbefugten Personen aus der sanitären Auslaufarmatur herausgedreht werden, da beim Drehen des Ringelementes das eigentliche Auslaufmundstück nicht mitdreht. Zum Montieren oder Demontieren des Auslaufmundstückes sowie des darin befindlichen sanitären Einsetzteiles ist ein spezielles Werkzeug erforderlich, das abströmseitig in das Auslaufmundstück eingeführt wird und so ein Ein- oder Ausschrauben des am Auslaufmundstück vorgesehenen Außengewindes am Innengewinde des Wasserauslaufs erlaubt.In order to prevent such a theft, sanitary outlet fittings of the type mentioned are known, the outlet mouthpiece at its outlet end side carries a slot, a profiling or similar tool engagement surface, wherein the outlet mouthpiece enclosing and serving as a vandalism ring element is freely rotatably mounted on the outlet end portion of the outlet nozzle , Thus, the outlet nozzle and the sanitary insert therein can not be unscrewed by unauthorized persons from the sanitary outlet fitting, as the actual outlet nozzle does not rotate when the ring element is turned. To assemble or disassemble the outlet nozzle and the sanitary insert therein, a special tool is required, which is introduced downstream in the outlet nozzle and thus allows a screwing or unscrewing the provided on the outlet nozzle external thread on the internal thread of the water outlet.

Nachteilig bei diesen vorbekannten Auslaufarmaturen ist jedoch, dass das am Auslaufmundstück frei drehbare Ringelement einen zusätzlichen, vergleichsweise großen Durchmesser hat, so dass das Ringelement vollständig über den Wasserauslauf der sanitären Auslaufarmatur vorsteht und die Auslaufarmatur dadurch unschön aussieht. Zudem ergibt sich bei Auslaufarmaturen mit gekrümmten Wasserauslauf bereichsweise ein unschöner Spalt zwischen dem Wasserauslauf der sanitären Auslaufarmatur einerseits und dem Ringelement des Auslaufmundstücks andererseits, so dass auch die Reinigung in diesem Bereich erschwert wird. Auch kann das frei drehbare Ringelement aufgrund seines zusätzlichen, vergleichsweise großen Durchmessers insbesondere bei gekrümmten Auslaufarmaturen, derart am Armaturenauslauf anstoßen, dass das Auslaufmundstück nicht vollständig in das Innengewinde der Auslaufarmatur eingeschraubt werden und die am gewindeseitigen Stirnende des Strahlreglers vorgesehene Ringdichtung ihre Dichtfunktion nicht erfüllen kann.A disadvantage of these known outlet fittings, however, is that the freely rotatable ring element on the outlet nozzle has an additional, relatively large diameter, so that the ring element protrudes completely over the water outlet of the sanitary outlet fitting and the outlet fitting looks unsightly. In addition, results in outlet fittings with curved water outlet regions, an ugly gap between the water outlet of the sanitary outlet fitting on the one hand and the ring member of the outlet nozzle on the other hand, so that the cleaning in this area is difficult. Also, the freely rotatable ring member due to its additional, relatively large diameter especially with curved outlet fittings, so abut the valve outlet that the outlet nozzle are not completely screwed into the internal thread of the outlet fitting and provided on the threaded end of the jet regulator ring seal their sealing function can not meet.

Aus der US 2 989 249 A kennt man bereits eine sanitäre Auslaufarmatur mit einem Wasserauslauf, der eine Aufnahmeöffnung mit einem Innengewinde aufweist. Der vorbekannten Auslaufarmatur ist ein hülsenförmiges Auslaufmundstück zugeordnet, das umfangseitig ein in das Innengewinde der Aufnahmeöffnung lösbar einschraubbares Außengewinde trägt. Im Hülseninneren des Auslaufmundstücks ist ein Strahlregler oder dergleichen sanitäres Einsetzteil gehalten. Das Auslaufmundstück trägt an seiner auslaufseitigen Stirnseite eine durch abwechselnd angeordnete Vor- und Rücksprünge der hülsenförmigen Umfangswandung gebildete kronenförmige Werkzeugangriffsfläche. Damit der noch über die Aufnahmeöffnung vorstehende Teil des Auslaufmundstücks einem Unberechtigten keine Angriffsfläche zum Ausdrehen des Auslaufmundstücks bieten kann, ist der gewindelose Teilbereich des Auslaufmundstücks mit einem, in Längsrichtung fixierten, jedoch um die Längsachse des Auslaufmundstücks frei drehbaren Ringelement umfasst. Vergleichbare Manipulationssicherungen für sanitäre Auslaufarmaturen sind auch aus der US 4 364 523 A sowie aus der US 3 827 636 A bekannt.From the US 2 989 249 A already known a sanitary outlet fitting with a water outlet, which has a receiving opening with an internal thread. The prior art outlet fitting is associated with a sleeve-shaped outlet mouthpiece, the peripherally carries a releasably screwed into the internal thread of the receiving opening external thread. In the sleeve interior of the outlet mouthpiece a jet regulator or the like sanitary insert part is held. The outlet mouthpiece carries at its outlet end face a formed by alternately arranged projections and recesses of the sleeve-shaped peripheral wall crown-shaped tool engagement surface. In order for the part of the outlet mouthpiece still projecting beyond the receiving opening to not offer an unauthorized person an attack surface for unscrewing the outlet mouthpiece, the threadless subregion of the outlet mouthpiece is comprised of a ring element fixed in the longitudinal direction but freely rotatable about the longitudinal axis of the outlet mouthpiece. Similar manipulation safeguards for sanitary outlet fittings are also from the US 4,364,523 A as well as from the US Pat. No. 3,827,636 A known.

Bei diesen vorbekannten Auslaufarmaturen kann jedoch der über den Wasserauslauf vorstehende und durch das frei drehbare Ringelement noch zusätzlich verbreiterte Teilbereich des Auslaufmundstücks das ästhetische Erscheinungsbild der sanitären Auslaufarmatur erheblich stören.In these prior art outlet fittings, however, the projecting beyond the water outlet and by the freely rotatable ring member even further widened portion of the outlet mouthpiece can significantly disturb the aesthetic appearance of the sanitary outlet fitting.

Es besteht daher die Aufgabe, eine sanitäre Auslaufarmatur der eingangs erwähnten Art zu schaffen, bei der ein sanitäres Einsetzteil noch besser gegen Diebstahl geschützt werden kann und die besser in den Armaturenauslauf integrierbar ist, um die Gestaltungsfreiheit bei der Herstellung und Konstruktion solcher sanitärer Auslaufarmaturen nicht einzuengen und um hierbei ästhetisch weniger störend zu sein.It is therefore an object to provide a sanitary outlet fitting of the type mentioned, in which a sanitary insert can be better protected against theft and which is better integrated into the tap spout to not restrict the freedom of design in the production and construction of such sanitary outlet fittings and to be aesthetically less disturbing.

Die erfindungsgemäße Lösung dieser Aufgabe besteht insbesondere darin, dass der lichte Innen-Durchmesser der Aufnahmeöffnung an deren äußeren Endbereich zumindest etwa dem Außen-Durchmesser des Auslaufmundstücks im Bereich seines frei drehbar gelagerten Ringelementes entspricht, dass die axiale Tiefe der Aufnahmeöffnung derart an die axiale Erstreckung des Auslaufmundstücks angepasst ist, dass das Auslaufmundstück nur mit einem Teilbereich der Längserstreckung seines Ringelementes über die Aufnahmeöffnung vorsteht, dass der Außendurchmesser des Ringelements etwa gleich dem oder kleiner als der Außendurchmesser des Auslaufmundstücks in dessen Gewindebereich ist, und dass dazu der das Ringelement tragende abströmseitige Teilbereich des Auslaufmundstücks im Vergleich zu dessen Gewindebereich einen reduzierten Außendurchmesser hat.The achievement of this object is in particular that the clear inner diameter of the receiving opening at the outer end region at least approximately corresponds to the outer diameter of the outlet nozzle in the region of its freely rotatably mounted ring member that the axial depth of the receiving opening in such a way to the axial extent of Adapted to the outlet nozzle, that the outlet nozzle protrudes beyond the receiving opening with only a partial region of the longitudinal extent of its ring element, that the outer diameter of the ring element is approximately equal to or smaller than the outer diameter of the outlet nozzle in its threaded portion, and that in addition to the the ring element bearing downstream side portion of the Outlet mouthpiece compared to the threaded portion has a reduced outer diameter.

Das Auslaufmundstück der erfindungsgemäßen Auslaufarmatur ist so am Wasserauslauf befestigt, dass es mit den Fingern oder einem außen angreifenden Werkzeug nicht herausgeschraubt werden kann. Es ist somit weder möglich, ein Werkzeug, beispielsweise eine Zange, umfangsseitig am Auslaufmundstück anzubringen, noch ist ein manuelles Drehen des Auslaufmundstücks möglich, so dass ein zuverlässiger Diebstahlschutz gegeben ist. Außerdem tritt das bis zu seinem Ringelement praktisch versenkt angeordnete Einsetzteil optisch nicht störend in Erscheinung und es besteht praktisch keine Angriffsmöglichkeit für Beschädigungen. Da das am Auslaufmundstück frei drehbar gehaltene Ringelement somit einem Teilbereich seiner Längserstreckung über die Aufnahmeöffnung der sanitären Auslaufarmatur vorsteht, wird selbst bei gekrümmten Auslaufarmaturen ein unschöner Spalt zwischen dem Wasserauslauf einerseits und dem Ringelement des Auslaufmundstücks andererseits vermieden.The outlet nozzle of the outlet fitting according to the invention is attached to the water outlet, that it can not be unscrewed with the fingers or an external attacking tool. It is thus not possible to attach a tool, such as a pair of pliers, circumferentially on the outlet nozzle, nor is a manual rotation of the outlet nozzle possible, so that a reliable theft protection is given. In addition, this occurs practically up to its ring element sunk arranged insert optically not disturbing in appearance and there is virtually no possibility of attack for damage. Since the ring member freely rotatably held at the outlet mouthpiece thus protrudes over a portion of its longitudinal extension over the receiving opening of the sanitary outlet fitting, an ugly gap between the water outlet on the one hand and the ring element of the outlet mouthpiece is avoided even with curved outlet fittings.

Da der das Ringelement tragende abströmseitige Teilbereich des Auslaufmundstücks im Vergleich zu dessen Gewindebereich einen reduzierten Außendurchmesser hat, ist der Außendurchmesser im Gewindbereich des Auslaufmundstücks derart reduziert ausgestaltet, dass der Außendurchmesser des Ringelements etwa gleich dem oder kleiner als der Außendurchmesser des Auslaufmundstücks im Gewindebereich ist. Der Innendurchmesser der Aufnahmeöffnung kann somit einen gleichbleibenden lichten Innendurchmesser aufweisen, da die Dicke des Ringelements durch den Rücksprung des Auslaufmundstücks aufgefangen wird. Die erfindungsgemäße Auslaufarmatur erlaubt somit das Eingreifen des Auslaufmundstücks in die Aufnahmeöffnung des Wasserauslaufs bis hin zum Ringelement selbst dann, wenn die Aufnahmeöffnung der Auslaufarmatur einen über ihre axiale Längserstreckung etwa gleichbleibenden lichten Innendurchmesser hat und selbst wenn zwischen dem lichten Innenumfang der Aufnahmeöffnung einerseits und dem Auslaufmundstück beziehungsweise seinem Ringelement andererseits nur ein vergleichsweise geringer Ringspalt oder dergleichen Freiraum verbleibt.Since the outflow-side portion of the discharge nozzle carrying the ring member has a reduced outer diameter compared to its threaded portion, the outer diameter in the threaded portion of the outlet nozzle is designed reduced such that the outer diameter of the ring member is approximately equal to or smaller than the outer diameter of the outlet nozzle in the threaded portion. The inner diameter of the receiving opening can thus have a constant inner diameter, since the thickness of the ring element is absorbed by the return of the outlet nozzle. The outlet fitting according to the invention thus allows the intervention of the outlet mouthpiece in the receiving opening of the water outlet to the ring element even if the receiving opening of the outlet fitting has a about its axial longitudinal extent approximately constant clear inner diameter and even if between the clear inner circumference of the receiving opening on the one hand and the outlet nozzle or his ring element on the other hand, only a comparatively small annular gap or the like free space remains.

Selbst wenn es gelingen sollte, an dem geringen Überstand des Ringelementes über die Aufnahmeöffnung der sanitären Auslaufarmatur ein Werkzeug anzusetzen, könnte das Auslaufmundstück selbst nicht herausgedreht werden, da nur das frei drehbare Ringelement mit dem Werkzeug bewegt werden würde.Even if it should succeed, on the small projection of the ring element on the receiving opening of the sanitary outlet fitting to set a tool, the outlet mouthpiece itself could not be unscrewed, since only the freely rotatable ring element would be moved with the tool.

Vorteilhaft kann es sein, dass die Aufnahmeöffnung des Wasserauslaufs einen innenliegenden Gewindebereich und einen sich vom Gewindebereich zum äußeren Einsetzende erstreckenden, verbreiterten Aufnahmebereich für das Ringelement des Auslaufmundstücks aufweist. Durch eine derartige stufenförmige Aufnahmeöffnung können auch herkömmliche Strahlregler, Durchflussmengenregler, Durchflußbegrenzer, Rückflußverhinderer oder andere sanitäre Einsetzteile für die erfindungsgemäße Auslaufarmatur verwendet werden.Advantageously, it may be that the receiving opening of the water outlet has an internal threaded portion and extending from the threaded portion to the outer insertion end, widened receiving area for the annular element of the outlet nozzle. By such a stepped receiving opening and conventional jet regulator, flow regulator, Durchflußbegrenzer, backflow preventer or other sanitary inserts can be used for the outlet fitting according to the invention.

Um auch die üblichen Strahlregler oder dergleichen sanitären Einsetzteile an der erfindungsgemäßen Auslaufarmatur befestigen zu können, ist es vorteilhaft, wenn der Außendurchmesser des sanitären Einsetzteiles im Gewindebereich ein genormtes Standard-Maß für Auslaufarmaturen aufweist.In order to attach the usual aerator or the like sanitary inserts to the outlet fitting according to the invention, it is advantageous if the outer diameter of the sanitary insert in the threaded portion has a standard standard measure for outlet fittings.

Weitere vorteilhafte Ausführungsformen ergeben sich aus den Ansprüchen sowie den nachfolgend beschriebenen Zeichnungen.Further advantageous embodiments will become apparent from the claims and the drawings described below.

In den Figuren 1 und 2 bzw. 3 und 4 sind zwei Ausführungsformen einer sanitären Auslaufarmatur 1 dargestellt. Die sanitäre Auslaufarmatur 1 weist einen Wasserauslauf 2 mit einer Aufnahmeöffnung 3 auf, die ein Innengewinde trägt. Der sanitären Auslaufarmatur 1 ist ein hülsenförmiges Auslaufmundstück 7 zugeordnet, das umfangsseitig ein in das Innengewinde der Aufnahmeöffnung 3 lösbar einschraubbares Außengewinde trägt. Im Hülseninneren des hülsenförmigen Auslaufmundstücks 7 ist ein sanitäres Einsetzteil 4 gehalten, das hier als Strahlregler ausgebildet ist. Das Auslaufmundstück 7 weist dazu an seinem Innenumfang einen Ringabsatz 21 auf, auf den in Gebrauchsstellung ein am zuströmseitigen Endbereich des sanitären Einsetzteiles 4 umfangsseitig vorstehender Ringflansch 22 aufliegt.In the Figures 1 and 2 or 3 and 4, two embodiments of a sanitary outlet fitting 1 are shown. The sanitary outlet fitting 1 has a water outlet 2 with a receiving opening 3, which carries an internal thread. The sanitary outlet fitting 1 is associated with a sleeve-shaped outlet nozzle 7, the circumferentially carries a releasably screwed into the internal thread of the receiving opening 3 external thread. In the sleeve interior of the sleeve-shaped outlet mouthpiece 7 a sanitary insert part 4 is held, which is designed here as a jet regulator. For this purpose, the outlet mouthpiece 7 has on its inner periphery an annular shoulder 21, on which, in the position of use, an inflow-side end region of the sanitary insert part 4 circumferentially projecting annular flange 22 rests.

Wie in den Figuren 5 bis 8 zu erkennen ist, weist das Auslaufmundstück 7 an seiner auslaufseitigen Stirnseite eine Werkzeugangriffsfläche auf, die hier durch zwei stirnrandseitig offene und auf gegenüberliegenden Seiten des Auslaufmundstückes 7 angeordnete Schlitze 23 gebildet wird. An dieser Werkzeugangriffsfläche ist ein in den Figuren 5 und 6 näher dargestelltes, als Montage- und Demontageschlüssel ausgebildetes (Spezial-)Werkzeug 20 ansetzbar, welches ein Ein- und Ausschrauben des am Auslaufmundstück 7 vorgesehenen Außengewindes im Innengewinde des an der Auslaufarmatur 1 vorgesehenen Wasserauslaufs 2 erlaubt.As in the FIGS. 5 to 8 it can be seen, the outlet mouthpiece 7 at its outlet-side end face on a tool engagement surface, which is here formed by two open at the end edge and arranged on opposite sides of the outlet nozzle 7 slots 23. At this tool engagement surface is in the FIGS. 5 and 6 closer illustrated, designed as an assembly and disassembly key (special) tool 20 can be attached, which allows screwing in and out of the provided on the outlet nozzle 7 external thread in the internal thread of the water outlet 2 provided on the outlet fitting 1.

Aus den Figuren 1 bis 8 wird deutlich, dass am auslaufseitigen Endbereich des Auslaufmundstücks 7 ein das Auslaufmundstück 7 umschließendes Ringelement 5 frei drehbar gelagert ist, dass als Vandalismussicherung dient. Dabei entspricht der lichte Innen-Durchmesser d1 der Aufnahmeöffnung 3 am äußeren Endbereich 10 zumindest etwa dem Außen-Durchmesser d2 des Auslaufmundstücks 7 im Bereich seines frei drehbar gelagerten Ringelementes 5; die axiale Tiefe 11 der Aufnahmeöffnung 3 ist derart an die axiale Erstreckung 12 des das Ringelement 5 umfassenden Auslaufmundstücks 7 angepasst, dass das Auslaufmundstück 7 nur mit einem Teilbereich der Längserstreckung seines Ringelementes 5 über die Aufnahmeöffnung 3 vorsteht. Dadurch ist das Auslaufmundstück 7 und das darin befindliche sanitäre Einsetzteil 4 mit samt dem Ringelement 5 im Wasserauslauf 2 der Auslaufarmatur 1 praktisch versenkt angeordnet, wodurch auch das optische Erscheinungsbild der Auslaufarmatur 1 verbessert ist.From the FIGS. 1 to 8 It is clear that at the outlet end portion of the outlet nozzle 7 a the outlet nozzle 7 enclosing ring member 5 is freely rotatably mounted, which serves as a vandalism protection. In this case, the clear inside diameter d1 of the receiving opening 3 at the outer end region 10 corresponds at least approximately to the outer diameter d2 of the outlet mouthpiece 7 in the region of its freely rotatably mounted ring element 5; the axial depth 11 of the receiving opening 3 is so adapted to the axial extent 12 of the annular element 5 comprehensive outlet nozzle 7 that the outlet nozzle 7 protrudes beyond the receiving opening 3 only with a partial region of the longitudinal extent of its ring element 5. As a result, the outlet nozzle 7 and the sanitary insert part 4 located therein together with the ring element 5 in the water outlet 2 of the outlet fitting 1 is arranged practically sunk, whereby the visual appearance of the outlet fitting 1 is improved.

Da der lichte Innen-Durchmesser d1 der Aufnahmeöffnung 3 und der Außen-Durchmesser d2 des Auslaufmundstücks 7 so bemessen sind, dass nur ein schmaler Spalt zwischen dem Wasserauslauf 2 und dem Ringelement 5 vorhanden bleibt, kann praktisch nur das für das Auslaufmundstück vorgesehene Spezialwerkzeug 20 zum Ein- und Ausschrauben des Auslaufmundstückes 7 an diesem angesetzt werden.Since the inside diameter d1 of the receiving opening 3 and the outside diameter d2 of the outlet nozzle 7 are so dimensioned are that only a narrow gap between the water outlet 2 and the ring member 5 remains present, practically only provided for the outlet nozzle special tool 20 for screwing and unscrewing the outlet nozzle 7 can be attached to this.

Durch die versenkte Anordnung des Auslaufmundstücks 7 und seines Ringelementes 5 ist ein Greifen des Auslaufmundstückes 7 beziehungsweise des Ringelements 5 mit der Hand unmöglich und auch ein Ansetzen einer Zange oder eines anderen handelsüblichen Werkzeuges am Außenumfang ist durch den geringen Überstand des Ringelements 5 über den Wasserauslauf 2 nicht möglich.Due to the recessed arrangement of the outlet nozzle 7 and its ring member 5 gripping the outlet nozzle 7 and the ring member 5 by hand is impossible and also applying a pair of pliers or other commercial tool on the outer periphery is due to the small projection of the ring member 5 on the water outlet. 2 not possible.

Neben der Verbesserung des Diebstahlsschutzes ist auch das optische Erscheinungsbild der hier dargestellten sanitären Auslaufarmatur 1 wesentlich verbessert.In addition to improving the theft protection and the visual appearance of the sanitary outlet fitting 1 shown here is significantly improved.

In den Figuren 2 und 4 ist zu erkennen, dass der Außendurchmesser des Ringelements etwa gleich dem Außendurchmesser des Auslaufmundstücks 7 in dessen Gewindebereich ist, und dass dazu der das Ringelement 5 tragende abströmseitige Teilbereich des Auslaufmundstücks 7 im Vergleich zu dessen Gewindebereich einen reduzierten Außendurchmesser hat. In diesem, einen reduzierten Außendurchmesser aufweisenden Teilbereich des Auslaufmundstücks sind die Wandstärken des Auslaufmundstücks 7 gegenüber vorbekannten Strahlreglern reduziert. Ein Auslaufmundstück 7 mit gegenüber dem Gewindedurchmesser verbreitetem Ringelement 5 könnte dann eingesetzt werden, wenn die Aufnahmeöffnung 3 des Wasserauslaufs im Bereich des Ringelementes 5 entsprechend vergrößert ist und eine weitgehend vollständige Aufnahme des Auslaufmundstücks 7 auch in diesem Teilbereich ermöglicht. Dies schränkt jedoch die Gestaltungsfreiheit bei der Herstellung und der Konstruktion des Armaturenauslaufs 1 ein.In the Figures 2 and 4 It can be seen that the outer diameter of the annular element is approximately equal to the outer diameter of the outlet nozzle 7 in its threaded portion, and that for the annular element 5 carrying downstream portion of the outlet nozzle 7 compared to the threaded portion has a reduced outer diameter. In this, a reduced outer diameter portion having the outlet nozzle, the wall thicknesses of the outlet nozzle 7 are reduced compared to prior art beam regulators. An outlet mouthpiece 7 with respect to the thread diameter disseminated ring element 5 could then be used if the receiving opening 3 of the water outlet in the region of the ring member 5 is increased accordingly and allows a substantially complete recording of the outlet nozzle 7 in this area. However, this limits the freedom of design in the manufacture and construction of the valve outlet 1.

Bei Auslaufarmaturen 1 mit einem gekrümmten Wasserauslauf 2, wie in Fig. 3 und 4 gezeigt, ist das Auslaufmundstück 7 häufig nicht rechtwinklig zur Unterseite des Wasserauslaufs 2 angeordnet. Da aber auch bei dieser Ausführungsform das Auslaufmundstück 7 nur mit einem Teilbereich der Längserstreckung seines Ringelementes 5 über die Aufnahmeöffnung 3 vorsteht, wird ein ansonsten bei außenliegendem Ringelement 5 zwischen Wasserauslauf 2 und Ringelement 5 verbleibender Ringspalt vermieden, der das Erscheinungsbild der Auslaufarmatur 1 verunstalten und das Reinigen in diesem Bereich erschweren kann und der oftmals, insbesondere bei stark gekrümmten Ausläufen, das dichte Verpressen der Ringdichtung 8 mit der innenliegenden Stirnfläche 9 der Aufnahmeöffnung 3 erschwert. Der Diebstahlsschutz für die sanitäre Auslaufarmatur gemäß den Figuren 3 und 4 ergibt sich auch hierbei durch die konstruktiven Maßnahmen, wie sie bereits für die Auslaufarmatur 1 gemäß den Figuren 1 und 2 beschrieben wurden.For outlet fittings 1 with a curved water outlet 2, as in 3 and 4 shown, the outlet nozzle 7 is often not arranged at right angles to the bottom of the water outlet 2. But since in this embodiment, the outlet nozzle 7 protrudes beyond the receiving opening 3 only with a portion of the longitudinal extent of its ring member 5, an otherwise external ring element 5 between the water outlet 2 and ring member 5 remaining annular gap is avoided, which deform the appearance of the outlet fitting 1 and the Cleaning in this area can complicate and often, especially in highly curved spouts, the dense compression of the ring seal 8 with the inner end face 9 of the receiving opening 3 difficult. Anti-theft protection for sanitary outlet fitting according to FIGS. 3 and 4 also results from the design measures, as they already for the outlet fitting 1 according to the Figures 1 and 2 have been described.

Aus den Figuren 5 und 6 wird deutlich, dass wegen des Ringelements 5 das Auslaufmundstück 7 nur mit dem von der Abströmseite her ansetzbaren Spezialwerkzeug montiert und demontiert werden kann. Ein Herausdrehen des Strahlreglers 4 von Hand oder mittels einer an das Ringelement 5 angesetzten Zange ist nicht möglich, da dabei nur das Ringelement 5, nicht jedoch das Auslaufmundstück 7 selbst gedreht wird. Das endlos drehende Ringelement 5 und die an der abströmseitigen Stirnseite des Auslaufmundstückes 7 vorgesehenen Werkzeugangriffsflächen bilden eine wirkungsvolle Vandalismussicherung. Zum einen geben Nicht-Fachleute schnell auf, wenn versucht wird, das Auslaufmundstück 7 und das darin befindliche sanitäre Einsetzteil 4 unberechtigt zu demontieren, und sich das Ringelement 5, das als einziger Kraftangriffspunkt bekannt ist, endlos dreht, weil das Gefühl eines endlosen "überdrehten" Gewindes gegeben wird. Zum anderen besteht eine Diebstahlsicherung auch dadurch, dass das Auslaufmundstück 7 und das darin befindliche sanitäre Einsetzteil 4 tatsächlich nur mit einem speziellen Schlüssel, der üblicherweise nur dem Service- oder Fachpersonal zur Verfügung steht, demontiert werden kann, den die üblichen Verkehrskreise der Armaturenbenutzer im öffentlichen Bereich, besonders im diebstahl- oder vandalismusgefährdeten öffentlichen Bereich, standardmäßig sicherlich nicht verfügbar haben.From the FIGS. 5 and 6 It is clear that because of the ring member 5, the outlet nozzle 7 can be assembled and disassembled only with the attachable from the downstream side special tool. Unscrewing the jet regulator 4 by hand or by means of an attached to the ring member 5 pliers is not possible, since only the ring member 5, but not the outlet nozzle 7 itself is rotated. The endlessly rotating ring element 5 and the tool engagement surfaces provided on the downstream end side of the outlet mouthpiece 7 form an effective vandalism protection. For one thing, non-professionals quickly give up trying to improperly disassemble the outlet mouthpiece 7 and the sanitary fitting 4 therein, and the ring element 5, which is known as a single force application point, rotates endlessly because of the feeling of an endless over-twisting " Thread is given. On the other hand, an anti-theft device also by the fact that the outlet nozzle 7 and the sanitary insert 4 located therein can actually be disassembled only with a special key, which is usually only the service or specialist personnel available, the usual public of the fitting users in public Range, especially in the theft or vandal-endangered public area, by default certainly not available.
