Description

Die vorliegende Erfindung betrifft eine Sanitärarmatur, welche einen einen Wasserauslauf aufweisenden Armaturenkörper und eine in dem Armaturenkörper angeordnete Ventileinheit umfasst, wobei die Ventileinheit einen Betätigungsansatz aufweist. Die Sanitärarmatur umfasst ferner einen an dem Betätigungsansatz angebrachten Betätigungsgriff, eine die Ventileinheit zumindest teilweise überdeckende Abdeckkappe und mindestens eine Lichtquelle.The present invention relates to a sanitary fitting, which comprises a fitting body having a water outlet and a valve unit arranged in the fitting body, the valve unit having an actuation attachment. The sanitary fitting further comprises an operating handle attached to the actuating attachment, a cover cap that at least partially covers the valve unit and at least one light source.

Aus DE 200 17 254 U1 ist beispielsweise eine Sanitärarmatur mit den vorgenannten Merkmalen bekannt, wobei die Lichtquelle so ausgebildet ist, dass ein nach vorne vorgebeugter Benutzer von unten angestrahlt werden kann. Zudem wird offenbart, dass mittels der Lichtquelle die Mischwassertemperatur angezeigt werden kann. Die Lichtquelle muss hierfür allerdings im Betätigungsgriff angeordnet sein. Dies macht einerseits den Schutz gegen Spritzwasser aufwändig und andererseits ist eine elektrische Kontaktierung der Lichtquelle aufgrund der erforderlichen Verbindung zu dem beweglichen Betätigungsgriff störungsanfällig. Eine Sanitärarmatur mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus WO 2014/195120 A2 bekannt. Weitere Sanitärarmaturen sind jeweils aus EP 3 351 695 A1 , EP 1 964 984 A1 und DE 20 2008 005 340 U1 bekannt.Out of DE 200 17 254 U1 For example, a sanitary fitting with the aforementioned features is known, the light source being designed in such a way that a user leaning forward can be illuminated from below. It is also disclosed that the mixed water temperature can be displayed using the light source. However, the light source must be located in the operating handle for this. On the one hand, this makes protection against splash water complex and, on the other hand, electrical contacting of the light source is prone to failure due to the required connection to the movable operating handle. A sanitary fitting with the features of the preamble of claim 1 is out WO 2014/195120 A2 known. Other plumbing fixtures are off EP 3 351 695 A1 , EP 1 964 984 A1 and DE 20 2008 005 340 U1 known.

Aufgabe der vorliegenden Erfindung ist es daher, die mit Bezug zum Stand der Technik geschilderten Nachteile zu beseitigen und insbesondere eine Sanitärarmatur anzugeben, bei der die Lichtquelle besser vor Spritzwasser geschützt ist und bei der die Kontaktierung der Lichtquelle vereinfacht ist.The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to provide a sanitary fitting in which the light source is better protected from splash water and in which contacting the light source is simplified.

Gelöst wird die Aufgabe durch eine Sanitärarmatur mit den Merkmalen des unabhängigen Anspruchs. Vorteilhafte Weiterbildungen der Sanitärarmatur sind in den abhängigen Ansprüchen und in der Beschreibung angegeben, wobei einzelne Merkmale der vorteilhaften Weiterbildungen in technisch sinnvoller Weise miteinander kombinierbar sind.The task is solved by a sanitary fitting with the features of the independent claim. Advantageous developments of the sanitary fitting are specified in the dependent claims and in the description, with individual features of the advantageous developments being able to be combined with one another in a technically sensible manner.

Die Aufgabe wird insbesondere durch eine Sanitärarmatur mit den eingangs genannten Merkmalen gelöst, wobei die Abdeckkappe aus einem lichtdurchlässigen Material gebildet ist und die Lichtquelle so ausgerichtet ist, dass zumindest ein Teil des von der Lichtquelle emittierten Lichts in die Abdecckappe eintritt, so dass die Abdeckkappe als leuchtender Körper wahrnehmbar ist.The object is achieved in particular by a sanitary fitting with the features mentioned at the outset, wherein the cover cap is formed from a translucent material and the light source is aligned such that at least part of the light emitted by the light source enters the cover cap, so that the cover cap as luminous body is perceptible.

Somit erfüllt die Abdeckkappe eine Doppelfunktion. Einerseits dient sie als teilweise Abdeckung und/oder Fixierung der in dem Armaturenkörper angeordneten Ventileinheit und andererseits kann sie als Anzeigefläche einer beispielsweise durch die Lichtfarbe angezeigten Information (wie Mischwassertemperatur) dienen.The cover cap therefore fulfills a dual function. On the one hand, it serves as a partial cover and/or fixation of the valve unit arranged in the fitting body and on the other hand, it can serve as a display surface for information displayed, for example, by the light color (such as mixed water temperature).

Die Ventileinheit ist insbesondere eine Einhebelmischkartusche, welche in dem Armaturenkörper angeordnet ist. Die Ventileinheit ist also eingangsseitig über entsprechende Anschlüsse an eine Heißwasserleitung und an eine Kaltwasserleitung anschließbar. Ausgangsseitig steht die in dem Armaturenkörper angeordnete Ventileinheit mit dem Wasserauslauf des Armaturenkörpers in strömungstechnischer Verbindung.The valve unit is in particular a single-lever mixing cartridge which is arranged in the fitting body. The valve unit can therefore be connected to a hot water pipe and a cold water pipe on the input side via appropriate connections. On the output side, the valve unit arranged in the fitting body is in fluid communication with the water outlet of the fitting body.

Die Ventileinheit kann über den Betätigungsansatz verstellt werden. Wenn die Ventileinheit als Einhebelmischkartusche ausgebildet ist, ist genau ein Betätigungsansatz vorgesehen, mit welchem sowohl der Durchfluss als auch die Mischwassertemperatur eingestellt werden kann. Der Betätigungsansatz ist hierzu bei einer Aufrechten Anordnung der Sanitärarmatur insbesondere um eine vertikale Achse drehbar und um eine horizontale Achse schwenkbar.The valve unit can be adjusted using the actuation attachment. If the valve unit is designed as a single-lever mixing cartridge, exactly one actuation approach is provided with which both the flow and the mixed water temperature can be adjusted. The actuation approach is For this purpose, with an upright arrangement of the sanitary fitting, it can be rotated in particular about a vertical axis and pivoted about a horizontal axis.

Die Ventileinheit wird zumindest teilweise von der Abdeckkappe überdeckt, was bedeutet, dass die Abdeckkappe zumindest mit der Ventileinheit überlappt und insbesondere bei einer Aufrechten Anordnung der Sanitärarmatur abschnittsweise oberhalb eines Gehäuses der Ventileinheit angeordnet ist.The valve unit is at least partially covered by the cover cap, which means that the cover cap at least overlaps with the valve unit and is arranged in sections above a housing of the valve unit, in particular when the sanitary fitting is arranged upright.

Die Abdeckkappe wird während der Montage der Sanitärarmatur in der Regel nach der Ventileinheit eingesetzt und ist insbesondere dazu vorgesehen, die Ventileinheit in dem Armaturenkörper zu fixieren.The cover cap is generally inserted after the valve unit during assembly of the sanitary fitting and is intended in particular to fix the valve unit in the fitting body.

Gleichzeitig ist die Abdeckkappe bevorzugt so ausgebildet, dass die Ventileinheit im montierten Zustand der Sanitärarmatur nicht sichtbar ist, wobei insbesondere ein zwischen dem Betätigungsgriff und dem Armaturenkörper ausgebildeter Spalt von der Abdeckkappe abgedeckt ist, so dass nur die Abdeckkappe und nicht die Ventileinheit durch den Spalt hindurch sichtbar ist.At the same time, the cover cap is preferably designed so that the valve unit is not visible in the assembled state of the sanitary fitting, in particular a gap formed between the operating handle and the fitting body being covered by the cover cap, so that only the cover cap and not the valve unit passes through the gap is visible.

Die Abdeckkappe ist beispielsweise in der Art einer Kuppe oder zumindest bereichsweise ringförmig ausgebildet, wobei die Abdeckkappe eine zentrale Öffnung aufweist, durch welche Öffnung sich der Betätigungsansatz der Ventileinheit und/oder der Betätigungsgriff hindurch erstreckt. Dabei ist der an dem Betätigungsansatz angebrachte Betätigungsgriff in der Regel so ausgebildet, dass die Öffnung in der Abdeckkappe von dem Betätigungsgriff vollständig überdeckt wird.The cover cap is, for example, in the form of a dome or at least partially annular, the cover cap having a central opening through which opening the actuating approach of the valve unit and/or the actuating handle extends. The operating handle attached to the operating attachment is generally designed in such a way that the opening in the cover cap is completely covered by the operating handle.

Die Lichtquelle kann also an einem ortsfesten Bauteil der Sanitärarmatur angebracht sein und somit nicht an dem beweglichen Betätigungsgriff. Die Sanitärarmatur ist insbesondere so ausgebildet, dass die Lichtquelle so ausgerichtet ist, dass das emittierte Licht in die Abdeckkappe eingekoppelt wird. Dabei ist die Lichtquelle so ausgerichtet und/oder die Abdeckkappe so ausgebildet, dass das in die Abdeckkappe eingekoppelte Licht an einer Oberfläche aus der Abdeckkappe gegebenenfalls diffus austreten kann. Insbesondere ist die Abdeckkappe so ausgebildet, dass aus der Oberfläche austretendes Licht durch den Spalt zwischen Betätigungsgriff und Armaturenkörper heraustritt. Somit kann die Abdeckkappe als entsprechend der Farbe des von der Lichtquelle emittierten Lichts leuchtender Anzeigekörper wahrgenommen werden.The light source can therefore be attached to a stationary component of the sanitary fitting and therefore not to the movable operating handle. The sanitary fitting is in particular designed so that the light source is aligned so that the emitted light is coupled into the cover cap. The light source is aligned and/or the cover cap is designed in such a way that that the light coupled into the cover cap can optionally emerge diffusely on a surface of the cover cap. In particular, the cover cap is designed such that light emerging from the surface emerges through the gap between the operating handle and the fitting body. The cover cap can therefore be perceived as a display body that lights up in accordance with the color of the light emitted by the light source.

Die Lichtquelle umfasst insbesondere mindestens eine LED und bevorzugte mehrere LEDs. Wenn mehrere LEDs vorgesehen sind, ist bevorzugt, dass zumindest zwei LEDs Licht mit unterschiedlicher Farbe emittieren, wobei das von den LEDs emittierte Licht so gemischt wird, dass ein Benutzer nur eine Farbe wahrnimmt. So können beispielsweise rotes Licht und blaues Licht emittierende LEDs benachbart zueinander angeordnet sein, so dass das für einen Benutzer wahrnehmbare Licht eine Mischfarbe zwischen Rot und Blau aufweisen kann, die von dem Verhältnis der Intensität des von den LEDs emittierten Lichts abhängt. Es kann aber auch nur rotes oder nur blaues Licht emittiert werden. Selbstverständlich können auch weitere LEDs zur Emission von Licht mit anderen Farben vorgesehen sein.The light source in particular includes at least one LED and preferably several LEDs. If multiple LEDs are provided, it is preferred that at least two LEDs emit light with different colors, the light emitted by the LEDs being mixed so that a user only perceives one color. For example, red light and blue light-emitting LEDs can be arranged adjacent to each other so that the light perceivable by a user can have a mixed color between red and blue, which depends on the ratio of the intensity of the light emitted by the LEDs. However, only red or only blue light can also be emitted. Of course, additional LEDs can also be provided for emitting light with other colors.

Prinzipiell wäre es ausreichend, wenn eine mehr oder weniger punktförmige Lichtquelle in dem Armaturenkörper angeordnet ist. In einer bevorzugten Ausführungsform ist die insbesondere mehrere LEDs umfassende Lichtquelle jedoch ringförmig angeordnet. Eine solche ringförmige Ausbildung der Lichtquelle ermöglicht es, das von der Lichtquelle emittierte Licht gleichmäßig in die Abdeckkappe einzukoppeln.In principle, it would be sufficient if a more or less point-shaped light source was arranged in the fitting body. In a preferred embodiment, however, the light source, in particular comprising a plurality of LEDs, is arranged in a ring. Such an annular design of the light source makes it possible to couple the light emitted by the light source evenly into the cover cap.

Prinzipiell kann das Licht der Lichtquelle aus jeder beliebigen Richtung in die Abdeckkappe eingekoppelt werden, beispielsweise (insbesondere in radialer Richtung) von der Seite. Bei einer ringförmigen Ausbildung der Abdecckappe kann die Einkopplung von radial innen oder radial außen erfolgen, wobei die Abdeckkappe so ausgebildet sein kann, dass eine Umlenkung des Lichts innerhalb der Abdeckkappe erfolgt.In principle, the light from the light source can be coupled into the cover cap from any direction, for example (particularly in the radial direction) from the side. With a ring-shaped design of the cover cap The coupling can take place from radially inside or radially outside, whereby the cover cap can be designed in such a way that the light is redirected within the cover cap.

Bevorzugt ist aber, dass die Abdeckkappe die Lichtquelle überdeckt, wobei ferner vorgesehen sein kann, dass die Lichtquelle Licht in einer Hauptabstrahlrichtung senkrecht (bei einer Aufrechten Anordnung der Sanitärarmatur) nach oben emittiert. Die Abdeckkappe ist also zumindest abschnittsweise oberhalb der Lichtquelle angeordnet. Mit einer solchen zumindest teilweisen Überdeckung wird die Lichtquelle durch die Abdeckkappe geschützt.However, it is preferred that the cover cap covers the light source, and it can also be provided that the light source emits light vertically upwards in a main emission direction (if the sanitary fitting is arranged upright). The cover cap is therefore arranged at least in sections above the light source. With such at least partial coverage, the light source is protected by the cover cap.

In einer Ausführungsform kann vorgesehen sein, dass der Armaturenkörper und die in dem Armaturenkörper angeordnete Ventileinheit eine Aufnahme ausbilden, in der die Lichtquelle angeordnet ist. Die Aufnahme ist also insbesondere ein Raum, der sowohl von dem Armaturenkörper als auch von der Ventileinheit begrenzt ist, wobei die Aufnahme insbesondere nach oben offen ausgebildet ist. Durch eine solche Anordnung der Lichtquelle in einer Aufnahme kann die Lichtquelle besonders einfach elektrisch kontaktiert werden.In one embodiment it can be provided that the fitting body and the valve unit arranged in the fitting body form a receptacle in which the light source is arranged. The receptacle is therefore in particular a space that is delimited by both the fitting body and the valve unit, the receptacle being designed to be open in particular at the top. By arranging the light source in a receptacle in this way, the light source can be electrically contacted particularly easily.

Die Aufnahme ist insbesondere kreisringförmig ausgebildet und erstreckt sich somit in Umfangsrichtung der insbesondere im Querschnitt kreisförmigen Ventileinheit.The receptacle is in particular circular ring-shaped and thus extends in the circumferential direction of the valve unit, which is particularly circular in cross section.

Es kann insbesondere vorgesehen sein, dass sich die Abdeckkappe zumindest teilweise in die Aufnahme erstreckt. Die Abdeckkappe weist also bevorzugt einen Ansatz auf, der in der durch die Ventileinheit und den Armaturenkörper begrenzten Aufnahme angeordnet ist. Die somit zumindest (bei einer Aufrechten Anordnung der Sanitärarmatur) teilweise oberhalb der Lichtquelle angeordnete Abdeckkappe schützt die Lichtquelle weiter vor Spritzwasser und Verschmutzungen.In particular, it can be provided that the cover cap extends at least partially into the receptacle. The cover cap therefore preferably has an extension which is arranged in the receptacle delimited by the valve unit and the fitting body. The cover cap, which is therefore at least partially arranged above the light source (when the sanitary fitting is arranged upright), further protects the light source from splashing water and dirt.

Um die Lichtquelle noch besser zu schützen, ist erfindungsgemäß vorgesehen, dass die Abdeckkappe und bevorzugt der in der Aufnahme angeordnete Ansatz eine bevorzugt nach unten offene Aussparung aufweist, in der die Lichtquelle angeordnet ist. Die Aussparung kann auf der radialen Innenseite oder Außenseite des in die Aufnahme eingesteckten Ansatzes der Abdeckkappe ausgebildet sein. Bevorzugt ist aber, dass die Aussparung in einer insbesondere nach unten gerichteten Stirnfläche der Abdeckkappe ausgebildet ist, so dass die Aussparung insbesondere sowohl auf der radialen Innen- als auch auf der radialen Außenseite von dem Material der Abdeckkappe begrenzt ist. Es besteht somit die Möglichkeit, dass die Lichtquelle zunächst in der Aussparung der Abdeckkappe angeordnet wird und dann gemeinsam mit der Abdeckkappe in die Aufnahme eingeführt wird. Somit wird auch die Montage der Sanitärarmatur vereinfacht.In order to protect the light source even better, it is provided according to the invention that the cover cap and preferably the extension arranged in the receptacle has a recess which is preferably open at the bottom and in which the light source is arranged. The recess can be formed on the radial inside or outside of the extension of the cover cap inserted into the receptacle. However, it is preferred that the recess is formed in a particularly downward-facing end face of the cover cap, so that the recess is delimited by the material of the cover cap, in particular on both the radial inside and on the radial outside. There is therefore the possibility that the light source is first arranged in the recess of the cover cap and then inserted into the receptacle together with the cover cap. This also simplifies the installation of the sanitary fitting.

Es kann auch vorgesehen sein, dass in der Abdeckkappe und insbesondere in dem in die Aufnahme eingesteckten Ansatz der Abdeckkappe eine Nut ausgebildet ist, in welcher eine Dichtung angeordnet ist. Die insbesondere über den gesamten Umfang der Abdeckkappe umlaufende Nut kann dabei auf der radialen Innenseite und/oder auf der radialen Außenseite angeordnet sein. In jeder Nut kann dabei eine beispielsweise als O-Ring ausgebildete Dichtung angeordnet sein, die somit die Abdeckkappe beziehungsweise den Ansatz der Abdeckkappe gegenüber dem Armaturenkörper oder die Abdeckkappe gegenüber der Ventileinheit abdichtet. Durch eine solche Anordnung ist somit die Lichtquelle noch besser gegen das Eindringen von Wasser geschützt.It can also be provided that a groove is formed in the cover cap and in particular in the extension of the cover cap inserted into the receptacle, in which a seal is arranged. The groove, which runs in particular over the entire circumference of the cover cap, can be arranged on the radial inside and/or on the radial outside. A seal designed, for example, as an O-ring can be arranged in each groove, which thus seals the cover cap or the extension of the cover cap from the fitting body or the cover cap from the valve unit. With such an arrangement, the light source is even better protected against the ingress of water.

In einer Ausführungsform kann vorgesehen sein, dass in den Betätigungsgriff ein lichtdurchlässiges Element, also ein Bauteil aus einem lichtdurchlässigen Material, eingelassen ist, wobei das lichtdurchlässige Element so angeordnet ist, dass von der Abdeckkappe transmittiertes Licht zu einer Oberseite des Betätigungsgriffs gelangen kann. Das lichtdurchlässige Element erstreckt sich also von einer Oberseite des Betätigungsgriffs zu einer der Abdeckkappe zugewandten Unterseite des Betätigungsgriffs, so dass aus der Abdeckkappe austretendes Licht in das lichtdurchlässige Element eingekoppelt werden kann und auf der Oberseite des Betätigungsgriffs austreten kann. Das lichtdurchlässige Element wird somit als leuchtendes Element wahrgenommen, welches in den Betätigungsgriff integriert ist. Das lichtdurchlässige Element kann dabei einen insbesondere kreisrunden Durchmesser von nicht mehr als 10 mm, bevorzugt nicht mehr als 5 mm, aufweisen. Alternativ kann das lichtdurchlässige Element auch eine rechteckförmige, insbesondere quadratische Querschnittsform insbesondere mit einer maximalen Kantenlänge von maximal 10 mm aufweisen.In one embodiment, it can be provided that a translucent element, i.e. a component made of a translucent material, is embedded in the operating handle, the translucent element being arranged in such a way that light transmitted from the cover cap can reach an upper side of the operating handle. The translucent element extends i.e. from an upper side of the operating handle to an underside of the operating handle facing the cover cap, so that light emerging from the covering cap can be coupled into the translucent element and can exit on the upper side of the operating handle. The translucent element is therefore perceived as a luminous element which is integrated into the operating handle. The translucent element can have a particularly circular diameter of not more than 10 mm, preferably not more than 5 mm. Alternatively, the translucent element can also have a rectangular, in particular square, cross-sectional shape, in particular with a maximum edge length of a maximum of 10 mm.

Die Erfindung sowie das technische Umfeld werden im Folgenden anhand der Figur beispielhaft erläutert. Die Figur zeigt einen Teil einer Sanitärarmatur in einer Schnittdarstellung.The invention and the technical environment are explained below using the figure as an example. The figure shows part of a sanitary fitting in a sectional view.

Die Sanitärarmatur umfasst einen Armaturenkörper 1, der einen Wasserauslauf ausbildet. In dem Armaturenkörper 1 ist eine Ventileinheit 2 angeordnet, die einen Betätigungsansatz 3 aufweist.The sanitary fitting includes a fitting body 1, which forms a water outlet. A valve unit 2, which has an actuation projection 3, is arranged in the fitting body 1.

An dem Betätigungsansatz 3 der als Einhebelmischkartusche ausgebildeten Ventileinheit 2 ist ein Betätigungsgriff 4 angebracht. In dem Betätigungsgriff 4 ist eine Ausnehmung ausgebildet, in der ein lichtdurchlässiges Element 9 angeordnet ist.An operating handle 4 is attached to the actuation attachment 3 of the valve unit 2 designed as a single-lever mixing cartridge. A recess is formed in the operating handle 4, in which a translucent element 9 is arranged.

Die Ventileinheit 2 und der Armaturenkörper 1 bilden gemeinsam eine Aufnahme 7 aus.The valve unit 2 and the fitting body 1 together form a receptacle 7.

In die Aufnahme 7 ist ein Ansatz einer Abdeckkappe 5 eingesteckt, wodurch die Abdeckkappe 7 fixiert wird. Die Abdeckkappe 5 weist eine Öffnung 12 auf, durch welche sich der Betätigungsansatz 3 der Ventileinheit 2 erstreckt. Die Öffnung 12 wird von dem Betätigungsgriff 4 überdeckt.An extension of a cover cap 5 is inserted into the receptacle 7, whereby the cover cap 7 is fixed. The cover cap 5 has an opening 12 on, through which the actuating projection 3 of the valve unit 2 extends. The opening 12 is covered by the operating handle 4.

Der in der Aufnahme 7 angeordnete Ansatz der Abdeckkappe 5 weist eine ringförmig umlaufende Aussparung 8 in seiner Stirnfläche auf. In der Aussparung 8 ist eine ringförmige Lichtquelle 6 angeordnet. Die Lichtquelle 6 umfasst LEDs, die Licht mit einer Hauptabstrahlrichtung nach oben emittieren, so dass das abgestrahlte Licht in die aus einem lichtdurchlässigen Material bestehende Abdeckkappe 5 eingekoppelt wird. Das so in die Abdeckkappe 5 eingekoppelte Licht kann außerhalb der Aufnahme 7 aus der Abdeckkappe 5 austreten und somit auch durch einen Spalt zwischen dem Betätigungsgriff 4 und dem Armaturenkörper 1. Die Abdeckkappe 5 kann somit als leuchtender Körper wahrgenommen werden. Wenn die Lichtquelle 6 Licht mit unterschiedlicher Farbe emittierende LEDs umfasst, so kann die Abdeckkappe 5 in unterschiedlichen Farben leuchten.The extension of the cover cap 5 arranged in the receptacle 7 has an annular recess 8 in its end face. An annular light source 6 is arranged in the recess 8. The light source 6 includes LEDs that emit light with a main emission direction upwards, so that the emitted light is coupled into the cover cap 5 made of a translucent material. The light coupled into the cover cap 5 in this way can emerge from the cover cap 5 outside the receptacle 7 and thus also through a gap between the operating handle 4 and the fitting body 1. The cover cap 5 can thus be perceived as a luminous body. If the light source 6 comprises LEDs emitting light with different colors, the cover cap 5 can light up in different colors.

Das aus der Abdeckkappe 5 austretende Licht kann zudem in das lichtdurchlässige Element 9 eingekoppelt werden und an einer Oberseite des Betätigungsgriffs 4 aus dem lichtdurchlässigen Element 9 heraustreten. Somit wird das lichtdurchlässige Element 9 als punktförmig leuchtender Körper wahrgenommen, der in der gleichen Farbe leuchtet wie die Abdeckkappe 5.The light emerging from the cover cap 5 can also be coupled into the translucent element 9 and emerge from the translucent element 9 on an upper side of the operating handle 4. The translucent element 9 is therefore perceived as a point-like luminous body that shines in the same color as the cover cap 5.

Damit die Lichtquelle 6 noch besser gegen eindringende Feuchtigkeit geschützt ist, weist die Abdeckkappe 5 an ihrem in der Aufnahme 7 angeordneten Ansatz eine umlaufende Nut 10 auf, in welcher ein O-Ring als Dichtung 11 angeordnet ist.So that the light source 6 is even better protected against penetrating moisture, the cover cap 5 has a circumferential groove 10 on its extension arranged in the receptacle 7, in which an O-ring is arranged as a seal 11.
