Description

Die Erfindung betrifft eine Unterdusche mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to an under shower with the features of the preamble of claim 1.

Die Erfindung ist insbesondere gerichtet auf eine Unterdusche als Zusatzmodul für ein herkömmliches WC, das keine Unterduschfunktion aufweist.The invention is directed in particular to an under shower as an additional module for a conventional toilet that does not have a shower function.

WCs mit Unterdusche sind auch als "Dusch-WCs" bekannt. Aus dem Markt bekannte Dusch-WCs weisen eine integrierte Duschfunktion für den Anal- und/oder Genitalbereich des Benutzers auf. Hierzu ist am Ende der Duscheinrichtung eine Düse angeordnet, durch die das Wasser in Richtung auf die zu reinigende Stelle austritt. Die Düse ist in aller Regel ausfahrbar, und zwar entweder elektromechanisch oder unter Wasserdruck. Im letztes Fall wird der Wasserdruck für die Speisung der Düse verwendet.Toilets with under-showers are also known as "shower toilets". Shower toilets known from the market have an integrated shower function for the anal and / or genital area of the user. For this purpose, a nozzle is arranged at the end of the shower device, through which the water exits in the direction of the area to be cleaned. The nozzle can usually be extended, either electromechanically or under water pressure. In the latter case, the water pressure is used to feed the nozzle.

Die Duscheinrichtung wird über ein Ventil gesteuert, über das die Wasserzufuhr geöffnet und gesperrt wird. Die Betätigung kann beispielsweise manuell - also durch Aufdrehen des Ventils - oder elektromechanisch erfolgen, wobei bei der elektromechanischen Steuerung ein Impuls ausgelöst wird, der ein Öffnen oder Schließen des Ventils bewirkt. Zusätzlich kann häufig die Durchflussmenge reguliert werden.The shower facility is controlled by a valve that opens and closes the water supply. The operation can for example be done manually - that is, by opening the valve - or electromechanically, with the electromechanical control triggering a pulse that causes the valve to open or close. In addition, the flow rate can often be regulated.

Dusch-WCs mit einer integralen Unterdusche sind hochentwickelte WCs, die je nach Ausstattung über weitere Funktionen verfügen, wie zum Beispiel Trockenfunktion, Heizfunktion des WC-Sitzes und dergleichen. Derartige Dusch-WCs haben sich grundsätzlich bewährt. Ihre Komplexität macht sie jedoch sehr teuer. Man ist daher dazu übergegangen als Alternative zu Dusch-WCs mit einer integralen Duscheinrichtung Duscheinrichtungen als Nachrüstteil für herkömmliche WCs anzubieten. Auf derartige Duscheinrichtungen ist die Erfindung insbesondere gerichtet.Shower toilets with an integral under-shower are highly developed toilets which, depending on the equipment, have additional functions such as drying function, heating function of the toilet seat and the like. Such shower toilets have basically proven their worth. However, their complexity makes them very expensive. One has therefore switched to offering shower devices as a retrofit part for conventional toilets as an alternative to shower toilets with an integral shower device. The invention is particularly directed to shower devices of this type.

Aus der DE 20 2006 013 209 ist eine Duscheinrichtung bekannt, die als Zusatzmodul zu einem herkömmlichen WC nachrüstbar ist. Die bekannte Duscheinrichtung weist eine Befestigungseinrichtung mit zwei Aussparungen auf. Durch die beiden Aussparungen greifen die Gewindestangen des WC-Sitz-Scharniers für die Befestigung des WC-Sitzes an dem WC-Becken. Die Duscheinrichtung wird zur Befestigung also zwischen dem WC-Sitz und dem Becken eingespannt.From the DE 20 2006 013 209 a shower device is known that can be retrofitted as an additional module to a conventional toilet. The known shower device has a fastening device with two recesses. The threaded rods of the toilet seat hinge for fastening the toilet seat to the toilet bowl reach through the two recesses. The shower device is therefore clamped between the toilet seat and the basin for attachment.

Die bekannte Duscheinrichtung gestattet eine kostengünstige Nachrüstung von herkömmlichen WCs. Für die Unterduschfunktion ist lediglich ein gesonderter Wasseranschluss erforderlich.The known shower facility allows cost-effective retrofitting of conventional toilets. A separate water connection is all that is required for the shower function.

Die bekannte Duscheinrichtung baut recht hoch. Dies hat zur Folge, dass der WC-Sitz in seinem hinteren Bereich ebenfalls ansteigt, so dass die Gefahr besteht, dass der WC-Sitz in seinem hinteren Abschnitt nicht mehr auf dem WC-Becken aufliegt. Neben optischen Einbußen kann dabei die Gefahr bestehen, dass eine Überbelastung des WC-Sitzes und/oder Duscheinrichtung auftreten.The well-known shower facility is quite high. As a result, the rear of the toilet seat is also increases, so that there is a risk that the rear section of the toilet seat will no longer rest on the toilet bowl. In addition to loss of appearance, there is a risk that the toilet seat and / or shower facility will be overloaded.

Aus der DE 94 14 893 ist eine Duscheinrichtung mit den Merkmalen des Oberbegriffs von Anspruch 1 bekannt, die recht schlank ausgebildet ist. Auch hier greifen die beiden Gewindestangen des WC-Sitzes durch die Aussparungen der Befestigungseinrichtung.
In beiden Fällen bietet die Befestigungseinrichtung wenig Flexibilität bei der Befestigung der Duscheinrichtung.
Hier greift die Erfindung ein.
Der Erfindung liegt die Aufgabe zugrunde, eine nachrüstbare Duscheinrichtung zu schaffen, die eine flache, stabile, haltbare und anpassungsfähige Gesamtanordnung gewährleistet.
From the DE 94 14 893 a shower device with the features of the preamble of claim 1 is known, which is quite slim. Here, too, the two threaded rods of the toilet seat engage through the recesses in the fastening device.
In both cases, the fastening device offers little flexibility in fastening the shower device.
This is where the invention comes in.
The invention has for its object to provide a retrofit shower facilities, which ensures a flat, stable, durable and adaptable overall arrangement.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Unterdusche mit den Merkmalen des Patentanspruchs 1.
Der Erfindung liegt der Grundgedanke zugrunde, dass eine besonders flache Konstruktion vorzugsweise dadurch geschaffen werden kann, dass die Leitung zumindest teilweise hinter den Aussparungen der Befestigungseinrichtung verläuft. Lediglich die Zuleitung zur Düse - die ihrerseits vorzugsweise vor der Befestigungseinrichtung angeordnet ist - ist zwischen den Aussparungen nach vorne geführt. Dieser Leitungsabschnitt kann technisch bedingt flach gehalten werden, und zwar insbesondere dann, wenn es sich um eine schlauchartige Leitung handelt, wie es als bevorzugt angesehen wird.
This object is achieved according to the invention by an under shower with the features of claim 1.
The invention is based on the basic idea that a particularly flat construction can preferably be created in that the line runs at least partially behind the cutouts in the fastening device. Only the feed line to the nozzle - which in turn is preferably arranged in front of the fastening device - is routed to the front between the cutouts. This line section can be kept flat for technical reasons, in particular when it is a hose-like line, as is considered preferred.

Der Befestigung der Unterdusche an dem WC-Becken kommt eine besondere Bedeutung zu. Sie muss einerseits flach und andererseits stabil ausgebildet sein. Eine besonders vorteilhafte Ausführungsform ist dadurch gekennzeichnet, dass die Befestigungseinrichtung zwei Befestigungslaschen aufweist. Die Befestigungslaschen bieten die Möglichkeit, zwischen dem Scharnier (für die Befestigung des WC-Sitz an dem Becken) und dem Becken eingespannt zu werden. Hierzu greifen Scharnierzapfen von Scharnieren durch die jeweilige Aussparung hindurch, die offen oder geschlossen, insbesondere als Langloch ausgebildet sein kann.The attachment of the under shower to the toilet bowl is of particular importance. It must be flat on the one hand and stable on the other. A particularly advantageous embodiment is characterized in that the fastening device has two fastening straps. The fastening straps offer the possibility of being clamped between the hinge (for fastening the toilet seat to the basin) and the basin. For this purpose, hinge pins of hinges reach through the respective recess, which can be open or closed, in particular designed as an elongated hole.

Zwei Befestigungslaschen bieten den Vorteil der Gewichtsersparnis. Dabei sind die Befestigungslaschen so ausgebildet, dass ihr Abstand zueinander veränderbar ist. Dies gewährleistet eine Anpassbarkeit an unterschiedliche Befestigungen von WC-Sitzen und/oder WC-Becken. An ihrem rückwärtigen Ende können die Befestigungslaschen zweckmäßig mit einem Gehäuse der Duscheinrichtung verbunden sein, wie es im Folgenden noch näher ausgeführt wird. Grundsätzlich sind für die Befestigungseinrichtung eine Vielzahl von Materialien denkbar, einschließlich Kunststoff. Besonders bewährt hat sich eine Befestigungseinrichtung aus Metall. Sie erfüllt in besonderem Maße die Forderung nach Stabilität bei gleichzeitig minimalem Platzbedarf. Vorzugsweise umfasst die Befestigungseinrichtung zwei gesonderte Befestigungslaschen, die jeweils vorteilhaft eine Aussparung aufweisen. Der Vorteil einer unabhängigen Anordnung der Befestigungslaschen liegt über den vorstehend geschilderten Vorteil der Anpassbarkeit hinaus darin, dass zwischen den Befestigungslaschen ausreichend Platz bleibt, um die Leitung zwischen den beiden Aussparungen nach vorne zu führen.Two fastening straps offer the advantage of saving weight. The fastening tabs are designed in such a way that their distance from one another can be changed. This ensures adaptability to different attachments of toilet seats and / or toilet bowls. At their rear end, the fastening tabs can be conveniently connected to a housing of the shower device, as will be explained in more detail below. In principle, a large number of materials are conceivable for the fastening device, including plastic. A fastening device made of metal has proven particularly useful. It particularly fulfills the requirement for stability with minimal space requirements at the same time. The fastening device preferably comprises two separate fastening tabs, each of which advantageously has a recess. The advantage of an independent arrangement of the fastening tabs lies beyond the above-described advantage of adaptability in that between the There is enough space for the fastening tabs to lead the cable between the two recesses to the front.

Die Befestigungseinrichtung weist zumindest im Bereich der Aussparungen vorteilhafterweise eine Höhe von maximal 10 mm, insbesondere von maximal 3 mm auf. Sofern die Befestigungseinrichtung aus Metall ausgebildet ist, ist eine ausreichende Stabilität auch denn gegeben, wenn die Befestigungseinrichtung deutlich dünner als 10 mm, insbesondere dünner als 3 mm, beispielsweise ca. 1 mm ausgebildet ist.The fastening device advantageously has a maximum height of 10 mm, in particular a maximum of 3 mm, at least in the region of the cutouts. If the fastening device is made of metal, sufficient stability is also given if the fastening device is made significantly thinner than 10 mm, in particular thinner than 3 mm, for example approx. 1 mm.

Erfindungsgemäß weist die Unterdusche ein Gehäuse mit vorzugsweise einer Unterseite und einer Oberseite auf. In dem Gehäuse ist die Leitung vorteilhaft geführt. Das Gehäuse schützt die in dem Gehäuse aufgenommenen Bauteile und gestattet deren Inspektion, wenn die Oberseite und die Unterseite lösbar miteinander verbunden sind, wie als vorteilhaft angesehen wird.According to the invention, the under shower has a housing with preferably an underside and an upper side. The line is advantageously guided in the housing. The housing protects the components received in the housing and allows their inspection when the top and bottom are detachably connected to one another, as is considered advantageous.

Zweckmäßig gehen die Befestigungslaschen von dem Gehäuse ab, und zwar vorteilhaft nach vorne. Insofern ist das Gehäuse vorzugsweise hinter den Befestigungslaschen (oder allgemein der Befestigungseinrichtung) angeordnet. Dies bedingt, dass im montierten Zustand das Gehäuse hinter dem WC-Sitz angeordnet sein kann, was nicht ausschließt, dass es sich auch seitlich an dem WC-Sitz nach vorne erstreckt, wie es im folgenden noch näher ausgeführt wird.The fastening tabs expediently extend from the housing, advantageously to the front. In this respect, the housing is preferably arranged behind the fastening tabs (or generally the fastening device). This means that, in the assembled state, the housing can be arranged behind the toilet seat, which does not rule out that it also extends laterally to the front of the toilet seat, as will be explained in more detail below.

Erfindungsgemäß ist die Befestigungseinrichtung in das Gehäuse, insbesondere in die Unterseite, eingehängt und relativ zu dem Gehäuse versetzbar. Durch das (seitliche) Versetzen der Befestigungseinrichtung kann die Unterdusche an unterschiedliche (vorgegebene) Öffnungen im WC-Becken für die WC-Sitz-Befestigungen angepasst werden. Hierzu weist die Unterseite vorzugsweise eine Rasterung auf, die mit der Befestigungseinrichtung zusammenwirkt. Die Rasterung verhindert ferner ein seitliches Verrutschen der montierten Unterdusche.According to the invention, the fastening device is suspended in the housing, in particular in the underside, and can be displaced relative to the housing. By shifting the fastening device (to the side), the under shower can be attached to different (predefined) openings in the toilet bowl for the toilet seat fixings can be adjusted. For this purpose, the underside preferably has a grid that interacts with the fastening device. The grid also prevents the installed under shower from slipping sideways.

Vorteilhafterweise ist die Befestigungseinrichtung zwischen der Oberseite und der Unterseite des Gehäuses eingespannt. Eine derartige Konstruktion gestattet eine einfache Festlegung der Befestigungseinrichtung an dem Gehäuse und gewährleistet darüber hinaus eine einfache Verstellbarkeit.The fastening device is advantageously clamped between the top and the bottom of the housing. Such a construction allows the fastening device to be easily fixed to the housing and also ensures simple adjustability.

In einigen Ländern müssen an gefährdeten Wasserentnahmestellen Sicherungsarmaturen eingebaut werden. Zu den gefährdeten Stellen zählt auch eine Unterdusche. Die Sicherungsarmaturen gewährleisten, dass gefährdete Entnahmestellen vor einem Rücksaugen, Rückdrücken oder Rückfließen von Nichttrinkwasser geschützt werden.In some countries, safety fittings must be installed at endangered water intake points. An under-shower is also one of the endangered areas. The safety fittings ensure that endangered tapping points are protected from non-potable water being sucked back, pushed back or flowed back.

Erfindungsgemäß ist in dem Gehäuse der Unterdusche eine Wasserabsicherung angeordnet. Bei der Wasserabsicherung kann es sich insbesondere um einen freien Auslauf mit Injektor handeln. Hierbei wird ein Wasserstrahl über einen Freiraum hinweg in eine Aufnahme gespritzt, die trichterartig sein kann. Im Falle eines Rücklaufens oder dergleichen von Wasser kann das (potentiell verunreinigte) Wasser aufgrund des Freiraumes nicht zurück über den Injektor in die Trinkwasserleitung gelangen. Über den Injektor ist es möglich, einen erforderlichen Mindestdruck zu erzielen, der benötigt wird, um die Düse gegen eine Rückstellkraft aus ihrer Ruhestellung in die Arbeitsstellung zu bewegen bzw. auszufahren.According to the invention, a water protection device is arranged in the housing of the under shower. The water protection can in particular be a free outlet with an injector. Here, a jet of water is sprayed over a free space into a receptacle, which can be funnel-like. In the event of a backflow or the like of water, the (potentially contaminated) water cannot get back via the injector into the drinking water line due to the free space. With the injector it is possible to achieve a required minimum pressure that is required to move or extend the nozzle from its rest position into the working position against a restoring force.

Bei einem freien Auslauf mit Injektor entsteht zum Beispiel durch Spritzwasser Leckage, die abgeführt werden muss. In diesem Zusammenhang wird vorgeschlagen, dass die Unterseite des Gehäuses einen Kanal für die Leckage bildet. Damit übernimmt die Unterseite vorzugsweise zwei Aufgaben, nämlich zum einen die Befestigung der Wasserabsicherung und zum anderen die Ableitung der Leckage in das WC. Zusätzlich oder alternativ kann vorgesehen sein, dass in dem Kanal die Zuleitung der Düse angeordnet ist.In the case of a free outlet with an injector, for example, splash water causes leakage that must be drained away. In this context, it is proposed that the underside of the housing forms a channel for the leakage. The underside thus preferably takes on two tasks, namely, on the one hand, fastening the water protection and, on the other hand, draining the leakage into the toilet. Additionally or alternatively it can be provided that the feed line of the nozzle is arranged in the channel.

Bei einer besonders vorteilhaften Ausführungsform ist die Wasserabsicherung hinter den Aussparungen angeordnet und die Unterseite erstreckt sich zwischen den beiden Aussparungen nach vorne. Da die Wasserabsicherung konstruktionsbedingt eine gewisse Höhe aufweist, ist sie bei der vorteilhaften Ausführungsform hinter den Aussparungen angeordnet, was zur Folge hat, dass sie sich im eingebauten Zustand hinter dem WC-Sitz befindet. Der Kanal hingegen kann flach gehalten und zwischen den Aussparungen nach vorne geführt sein. Durch diese Maßnahme bedarf es vorteilhaft keiner Erhöhung des (bestehenden) WC-Sitzes.In a particularly advantageous embodiment, the water protection is arranged behind the cutouts and the underside extends forward between the two cutouts. Since the water protection has a certain height due to the design, it is arranged behind the recesses in the advantageous embodiment, with the result that it is located behind the toilet seat in the installed state. The channel, on the other hand, can be kept flat and guided forward between the recesses. This measure advantageously means that there is no need to increase the (existing) toilet seat.

Eine besonders vorteilhafte Konstruktion ist dadurch gekennzeichnet, dass die Düse an einem freien Ende der Unterseite des Gehäuses angeordnet ist. Insbesondere kann die Düse an der Unterseite befestigt sein. Als besonders vorteilhaft wird es angesehen, wenn die Düse durch den Wasserdruck ausfahrbar ist, und zwar vorzugsweise (im eingebauten Zustand) nach unten, insbesondere im wesentlichen senkrecht nach unten. Die Düse selbst weist einen Spritzwinkel auf, der nach oben gerichtet ist.A particularly advantageous construction is characterized in that the nozzle is arranged at a free end of the underside of the housing. In particular, the nozzle can be attached to the underside. It is considered to be particularly advantageous if the nozzle can be extended by the water pressure, specifically preferably downwards (in the installed state), in particular essentially vertically downwards. The nozzle itself has a spray angle that is directed upwards.

Die Oberseite des Gehäuses deckt vorzugsweise den Kanal ab. Darüber hinaus kann vorgesehen sein, dass die Oberseite auch die Düse abdeckt. Hierzu bildet die Oberseite zweckmäßig in ihrem Endbereich eine nach unten gerichtete Abdeckung. Im Bedarfsfall fährt die Düse über die Abdeckung hinaus nach unten aus.The top of the housing preferably covers the channel. In addition, it can be provided that the top also covers the nozzle. For this purpose, the upper side expediently forms a downwardly directed cover in its end region. If necessary, the nozzle extends downwards beyond the cover.

Die Erfindung ist ferner gerichtet auf ein WC mit einer Unterdusche. Das WC weist einen WC-Sitz auf, dessen Befestigung an dem WC-Becken gleichzeitig die Befestigung der Unterdusche zur Verfügung stellt. Insbesondere ist vorteilhafterweise die Befestigungseinrichtung mit derjenigen Befestigung an dem WC-Becken des WC's festgelegt, mit der auch der WC-Sitz an dem WC-Becken an dem WC-Becken festgelegt ist. Bei der Befestigung kann es sich z.B. um zwei Scharniere bzw. Scharnierzapfen handeln. Ein Kerngedanke der Erfindung besteht auch darin, dass die Unterdusche ihrerseits kein Scharnier für den WC-Sitz bildet.The invention is also directed to a toilet with an under shower. The toilet has a toilet seat, the attachment of which to the toilet bowl also provides the attachment of the under-shower. In particular, the fastening device is advantageously secured to the toilet bowl of the toilet with that fastening with which the toilet seat on the toilet bowl is also fastened to the toilet bowl. The fastening can be, for example, two hinges or hinge pins. A core idea of the invention is that the shower head does not form a hinge for the toilet seat.

Im folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels im Zusammenhang mit der anhängenden Zeichnung näher erläutert. Die Zeichnung zeigt in:

Figur 1 zeigt eine erfindungsgemäße Duscheinrichtung in einer perspektivischen Darstellung. Die Duscheinrichtung besteht aus drei wesentlichen Komponenten, und zwar einem Ventil 1, einer Wasserabsicherung 2 und einer Düse 3. Das Ventil 1 und die Wasserabsicherung 2 sind über eine Leitung 4 miteinander verbunden. Gleiches gilt für die Wasserabsicherung 2 und die Düse 3. Figure 1 shows a shower device according to the invention in a perspective view. The shower device consists of three essential components, namely a valve 1, a water safety device 2 and a nozzle 3. The valve 1 and the water safety device 2 are connected to one another via a line 4. The same applies to water protection 2 and nozzle 3.

Das Ventil 1 ist über einen Drehknopf 5 (siehe Figur 2) betätigbar und über einen rückwärtigen Anschluss 6 an eine nicht dargestellte Wasserleitung angeschlossen. Dreht der Benutzer das Ventil 1 auf, gelangt Wasser durch den Leitungsabschnitt 4, die Wasserabsicherung 2, den nachfolgenden Leitungsabschnitt 4 und tritt aus der Düse 3 aus. Die Düse 1 ist so ausgebildet, dass sie entgegen einer Rückstellkraft ausfährt, und zwar in Richtung des Pfeils P1 senkrecht nach unten. Durch die Düse 3 gelangt das Wasser in den zu reinigenden Bereich des Benutzers.The valve 1 is via a rotary knob 5 (see Figure 2 ) operable and connected via a rear connection 6 to a water pipe, not shown. If the user turns on the valve 1, water passes through the line section 4, the water protection 2, the subsequent line section 4 and emerges from the nozzle 3. The nozzle 1 is designed in such a way that it extends against a restoring force, specifically in the direction of the arrow P1 vertically downwards. The water reaches the area of the user to be cleaned through the nozzle 3.

Bei der Wasserabsicherung 2 handelt es sich vorzugsweise um eine Absicherung nach DIN EN1717, die insbesondere einen freien Auslauf mit Injektor aufweist. Etwaige Leckage wird durch Öffnungen 7 der Wasserabsicherung 2 nach Außen abgeleitet.The water protection 2 is preferably a protection according to DIN EN1717, which in particular has a free outlet with an injector. Any leakage is diverted to the outside through openings 7 of the water protection 2.

Vorzugsweise sind das Ventil 1, die Wasserabsicherung 2 und die Düse 3 an einem Unterteil 8 eines Gehäuses 9 (siehe Figur 2) festgelegt. Das Unterteil 8 bildet einen Kanal 10, über den die Leckage in ein WC-Becken ablaufen kann. Gleichzeitig dient der Kanal 10 zur Aufnahme der Leitung 4.The valve 1, the water protection 2 and the nozzle 3 are preferably fixed to a lower part 8 of a housing 9 (see FIG. 2). The lower part 8 forms a channel 10, through which the leakage can drain into a toilet bowl. At the same time, the channel 10 serves to accommodate the line 4.

Die Unterdusche wird über eine Befestigungseinrichtung an dem WC-Becken festgelegt, die bei dem gezeigte bevorzugten Ausführungsbeispiel aus zwei Laschen 11, 12 besteht, die bevorzugt aus Metall ausgebildet sind, was eine besonders flache und gleichwohl stabile und haltbare Bauweise gestattet. Die Laschen 11, 12 weisen jeweils ein Loch 13 auf, das bevorzugt als Langloch ausgebildet ist und durch das jeweils ein Scharnier des WC-Sitzes greift, wie es im Zusammenhang mit Figur 4 näher beschrieben wird. Alternativ zu den beiden Befestigungslaschen kann eine einteilige Befestigungseinrichtung vorgesehen sein.The under shower is fixed to the toilet bowl via a fastening device which, in the preferred embodiment shown, consists of two tabs 11, 12, which are preferably made of metal, which allows a particularly flat and at the same time stable and durable construction. The tabs 11, 12 each have a hole 13, which is preferably designed as an elongated hole and through which a hinge of the toilet seat engages, as it is in connection with Figure 4 is described in more detail. As an alternative to the two fastening straps, a one-piece fastening device can be provided.

Die Befestigungslaschen 11, 12 sind in die Unterseite 8 des Gehäuses 9 eingehängt und vorzugsweise unabhängig voneinander relativ zu dem Gehäuse 9 für ihre Einstellung bewegbar. Die Unterseite 8 weist eine Rasterung 14 auf, die mit der jeweiligen Lasche 11, 12 zusammenwirkt. Die Rasterung 14 bietet für die Laschen 11, 12 zusätzlichen Halt und verhindert, dass die Duscheinrichtung ungewollt seitlich verrutscht.The fastening tabs 11, 12 are suspended in the underside 8 of the housing 9 and preferably can be moved independently of one another relative to the housing 9 for their adjustment. The underside 8 has a grid 14 which interacts with the respective tab 11, 12. The grid 14 provides additional support for the tabs 11, 12 and prevents the shower device from unintentionally slipping sideways.

Figur 2 zeigt die Unterdusche mit geschlossenem Gehäuse 9. Hierzu ist auf die Unterseite 8 des Gehäuses eine Oberseite 15 aufgeclipst, aufgeklebt oder aufgeschraubt. Durch das Gehäuse ist die Unterdusche staubgeschützt und einfach zu reinigen. Figure 2 shows the under shower with the housing 9 closed. For this purpose, a top 15 is clipped, glued or screwed onto the underside 8 of the housing. Thanks to the housing, the under shower is dust-proof and easy to clean.

Das Gehäuse 9 bildet mit seiner Oberseite 15 einen Arm 16, der sich zwischen den Laschen 11, 12 nach vorne erstreckt und vorzugsweise in seinem Endbereich eine nach unten abgehende Abdeckung 17 bildet. Die Abdeckung 17 schützt die Düse 3 in ihrer Ruhestellung vor Verschmutzung. Erst bei Betätigung des Betätigungsknopfs 5 fährt die Düse 3 unter Wasserdruck aus ihrer Ruhestellung in die Arbeitsstellung nach unten, so dass sie unter der Abdeckung hervortritt und den Wasserstrahl frei abgeben kann.With its upper side 15, the housing 9 forms an arm 16 which extends forward between the tabs 11, 12 and preferably a downwardly extending one in its end region Cover 17 forms. The cover 17 protects the nozzle 3 from soiling in its rest position. Only when the actuating button 5 is actuated does the nozzle 3 move under water pressure from its rest position into the working position downwards, so that it emerges from under the cover and can freely emit the water jet.

Figur 3 zeigt die Unterdusche auf einem WC-Becken 18. Das WC- Becken 18 weist zwei Öffnungen 19 auf, durch die zwei (in Figur 4 gezeigte) Scharniere 20 greifen. In diesem Zusammenhang sei darauf hingewiesen, dass Scharniere heutzutage auch mehrteilig ausgebildet sein können. Beispielsweise können sie einen Scharnierzapfen und einen lösbar damit verbundenen Scharnieraufsatz aufweisen. Derartige mehrteilige Scharniere sollen von dem Begriff Scharnier mitumfasst sein. Über das Langloch 13 ist die Unterdusche an die Form des WC-Beckens 18 und/oder des WC-Sitzes anpassbar. Figure 3 shows the under-shower on a toilet bowl 18. The toilet bowl 18 has two openings 19 through which two (in Figure 4 the hinges 20 shown). In this context, it should be pointed out that nowadays hinges can also be designed in several parts. For example, they can have a hinge pin and a hinge attachment detachably connected to it. Such multi-part hinges are intended to be encompassed by the term hinge. The under-shower can be adapted to the shape of the toilet bowl 18 and / or the toilet seat via the elongated hole 13.

Es wird auf Figur 4 Bezug genommen, aus der hervorgeht, dass die Laschen 11, 12 zwischen dem WC-Becken und den Scharnieren 20 eingespannt sind. Im Übrigen sei anhand des Koordinatensystems noch einmal verdeutlicht, was unter den Ortsangaben Oben, Unten, Vorne und Hinten (bzw. Rückseite) verstanden wird. Diese orientieren sich an der üblichen Bezeichnung anhand eines WC's. Dies gilt auch für die Bezugnahmen auf die Duscheinrichtung. Aus Figur 4 wird auch deutlich, dass die (hier von der Gehäuseoberseite 15 verdeckte) Leitung 4 in der Draufsicht hinter den Scharnieren 20 verläuft und zwischen den Scharnieren 20 nach vorne geführt ist.It will be on Figure 4 Reference, from which it can be seen that the tabs 11, 12 are clamped between the toilet bowl and the hinges 20. Incidentally, the coordinate system should once again make it clear what is understood by the location information above, below, front and rear (or rear side). These are based on the usual designation based on a toilet. This also applies to the references to the shower equipment. Out Figure 4 it is also clear that the line 4 (here covered by the upper side 15 of the housing) runs behind the hinges 20 in the top view and is guided forward between the hinges 20.

Figur 5 zeigt ein mit einer erfindungsgemäßen Unterdusche bestücktes WC mit einem WC-Sitz 21. Durch die erfindungsgemäße Unterdusche findet besonders vorteilhaft keine nennenswerte Erhöhung des WC-Sitzes 21 statt. Dies wird dadurch erreicht, dass lediglich die dünnen Befestigungslaschen 11, 12 vorzugsweise aus Metall zwischen dem WC-Sitz 21 und dem WC-Becken 18 eingespannt werden. Die höheren Aufbauten wie zum Beispiel die Wasserabsicherung 2 sind hinter dem WC-Sitz 21 angeordnet. Figure 5 shows a toilet equipped with an under-shower according to the invention with a toilet seat 21. The under-shower according to the invention particularly advantageously does not have any noteworthy features Raising the toilet seat 21 instead. This is achieved in that only the thin fastening tabs 11, 12, preferably made of metal, are clamped between the toilet seat 21 and the toilet bowl 18. The higher structures such as the water protection 2 are arranged behind the toilet seat 21.
