Description

Die Erfindung betrifft einen WC-Aufsatz, mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a toilet seat with the features of the preamble of patent claim 1.

WCs mit Duscheinrichtung 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 letzterem Fall wird der Wasserdruck für die Speisung der Düse verwendet.Toilets with shower facilities are also known as "shower toilets". Shower toilets known from the market have an integrated shower function for the user's anal and/or genital area. For this purpose, a nozzle is arranged at the end of the shower device, through which the water emerges 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 actuation can, for example, manually - that is, by opening the valve - or done electromechanically, with the electromechanical control a pulse is triggered, the 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. Hierbei kommt der erfindungsgemäße WC-Aufsatz zum Einsatz.Shower toilets with an integral bidet are highly developed toilets that, 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 themselves. However, their complexity makes them very expensive. A move has therefore been made to offering shower facilities as a retrofit part for conventional toilets as an alternative to shower toilets with an integral shower facility. The toilet attachment according to the invention is used here.

Aus der DE 20 2006 013 209 U1 ist ein WC-Aufsatz bekannt, der als Zusatzmodul zu einem herkömmlichen WC nachrüstbar ist. Der WC-Aufsatz weist eine Duscheinrichtung und eine Wasserabsicherung auf, die auf einer Bodenplatte montiert und über eine schlauchartige Leitung miteinander verbunden sind. Bei der Wasserabsicherung handelt es sich um einen freien Auslauf mit Injektor. Hierbei wird ein Wasserstrahl über einen Freiraum hinweg in eine Aufnahme gespritzt, die trichterartig ausgebildet ist. Durch den Freiraum kann das Wasser nicht zurück zum Injektor laufen. Eine Verunreinigung des Wasser ist dadurch unmöglich.From the DE 20 2006 013 209 U1 a toilet attachment is known, which can be retrofitted as an additional module to a conventional toilet. The toilet attachment has a shower device and a water safety device, which are mounted on a base plate and connected to one another via a hose-like line. The water protection is a free outlet with an injector. In this case, a water jet is sprayed across a free space into a receptacle that is designed like a funnel. The water cannot run back to the injector through the free space. Contamination of the water is therefore impossible.

Die Leckage läuft unmittelbar von der Wasserabsicherung in das WC-Becken. Hierzu greift die Wasserabsicherung in eine in der Bodenplatte ausgebildete Aussparung ein, die über dem WC-Becken angeordnet ist.The leakage runs directly from the water protection into the toilet bowl. For this purpose, the water safeguard engages in a recess formed in the base plate, which is arranged above the toilet bowl.

Der bekannte WC-Aufsatz gestattet eine kostengünstige Nachrüstung von herkömmlichen WCs. Für die Unterduschfunktion ist lediglich ein gesonderter Wasseranschluss erforderlich.The well-known toilet attachment allows for inexpensive retrofitting of conventional toilets. Only a separate water connection is required for the shower function.

Allerdings wurde gefunden, dass der Aufbau des bekannten WC-Aufsatzes nicht optimal ist. Insbesondere ist durch den Durchgriff der Wasserabsicherung durch die Bodenplatte hindurch die Position der Wasserabsicherung festgelegt.However, it was found that the structure of the known toilet seat is not optimal. In particular, the position of the water protection is fixed by the passage of the water protection through the base plate.

Aus der EP 1 234 921 A1 ist ein gattungsgemäßer WC-Aufsatz bekannt, der eine Duscheinrichtung aufweist. Zur Betätigung der Duscheinrichtung ist eine Vielzahl von Komponenten vorgesehen, die unter einem Deckel angeordnet sind.From the EP 1 234 921 A1 a generic toilet attachment is known which has a shower facility. A large number of components, which are arranged under a cover, are provided for actuating the shower device.

Aus der FR 2 230 076 A1 ist ein WC-Aufsatz in Form eines WC-Sitzes bekannt, in dem eine Duscheinrichtung ausgebildet ist. Der WC-Sitz weist eine Aussparung auf, in der eine Wasserabsicherung angeordnet ist.From the FR 2 230 076 A1 a toilet attachment in the form of a toilet seat is known, in which a shower device is formed. The toilet seat has a recess in which a water safety device is arranged.

Aus der US 3,455,423 ist eine Wasserabsicherung bekannt, bei der Wasser vertikal über einen Freiraum gespritzt wird. Der Freiraum verhindert ein Rückfließen des Wassers.From the U.S. 3,455,423 a water protection is known in which water is sprayed vertically over a free space. The free space prevents the water from flowing back.

Der Erfindung liegt die Aufgabe zugrunde, einen WC-Aufsatz zu schaffen, dessen Wartung erleichtert wird.The object of the invention is to provide a toilet seat which is easier to maintain.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen WC-Aufsatz mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention by a toilet seat with the features of patent claim 1.

Der Erfindung liegt die Erkenntnis zugrunde, dass die relative Anordnung der Wasserabsicherung zu der Duscheinrichtung einen wesentlichen Einfluss auf deren Funktionalität hat. Tests haben ergeben, dass ein möglichst kurzer Leitungsweg möglichst ohne Krümmung zu einer deutlich geringeren Leckage und gleichzeitig zu einer höheren Durchflussmenge führt.The invention is based on the finding that the relative arrangement of the water safeguard to the shower device has a significant influence on its functionality. Tests have shown that the shortest possible line route without any bends leads to significantly less leakage and at the same time to a higher flow rate.

Bei dem bekannten WC-Aufsatz aus der DE 20 2006 013 209 U1 ist die Position der Wasserabsicherung in Bezug auf die Duscheinrichtung vorgegeben. Der Kanal vom vorliegenden WC-Aufsatz hingegen gestattet eine deutlich flexiblere Anordnung der Wasserabsicherung, die insbesondere so getroffen wird, dass die Wasserabsicherung unweit der Duscheinrichtung angeordnet wird. Die Leckage wird durch den Kanal abgeleitet.In the well-known toilet essay from the DE 20 2006 013 209 U1 the position of the water protection in relation to the shower facility is specified. The channel of the present toilet attachment, on the other hand, allows for a much more flexible arrangement of the water safeguard, which is in particular made in such a way that the water safeguard is arranged not far from the shower facility. The leakage is diverted through the channel.

Bei einer vorteilhaften Ausführungsform der Erfindung befindet sich der Wasseranschluss der Duscheinrichtung in der hinteren Hälfte der Duscheinrichtung. Konsequenterweise wird es als vorteilhaft angesehen, auch die Wasserabsicherung frei, vorzugsweise im hinteren Bereich des WC-Aufsatzes, anzuordnen. Dabei gestattet der Kanal eine optimale Platzierung der Wasserabsicherung. Der Kanal sorgt für eine sichere Ableitung von Leckage, Spritzwasser oder dergleichen in das WC-Becken.In an advantageous embodiment of the invention, the water connection of the shower device is located in the rear half of the shower device. Consequently, it is considered advantageous to arrange the water protection freely, preferably in the rear area of the toilet seat. The channel allows an optimal placement of the water protection. The channel ensures that leaks, splash water or the like are safely discharged into the toilet bowl.

Wie auch im Stand der Technik ist die Wasserabsicherung mit der Duscheinrichtung über eine schlauchartige Leitung verbunden. Es hat sich gezeigt, dass eine maximale Schlauchlänge von 10 cm einen Betrieb mit minimaler Leckage gewährleistet.As in the prior art, the water safeguard is connected to the shower facility via a hose-like line. It has been shown that a maximum 10 cm hose length ensures operation with minimal leakage.

Vorzugsweise weist der WC-Aufsatz eine Bodenplatte auf. Eine derartige Konstruktion bietet den Vorteil, dass sämtliche Komponenten auf der Bodenplatte angeordnet sein können. Dies erleichtert zum einen die Wartung. Zum anderen bietet eine (vorteilhafterweise einteilige) Bodenplatte auch eine stabile Grundlage für den Gesamtaufbau des WC-Aufsatzes.The toilet seat preferably has a base plate. Such a construction offers the advantage that all components can be arranged on the base plate. On the one hand, this facilitates maintenance. On the other hand, a (advantageously one-piece) base plate also offers a stable basis for the overall structure of the toilet seat.

Die Bodenplatte besteht vorzugsweise aus Kunststoff und kann beispielsweise als Spritzgussteil hergestellt sein. Als besonders vorteilhaft wird es angesehen, wenn der Kanal integral mit der Bodenplatte ausgebildet ist.The base plate is preferably made of plastic and can be produced, for example, as an injection molded part. It is considered to be particularly advantageous if the channel is formed integrally with the base plate.

In wesentlicher Weiterbildung der Erfindung wird vorgeschlagen, dass die Bodenplatte einen vorzugsweise als Öffnung ausgebildeten Auslass aufweist, in dem der Kanal mündet. Durch den Auslass gelangt die Leckage vorteilhaft in das WC-Becken, und zwar durch die Bodenplatte hindurch nach unten. Der Auslass hat neben dem erheblichen Vorteil der direkten Ableitung auch den Vorteil, dass er für den Benutzer nicht sichtbar ist.In an essential development of the invention, it is proposed that the base plate has an outlet, preferably designed as an opening, into which the channel opens. The leakage advantageously reaches the toilet bowl through the outlet, specifically downwards through the base plate. In addition to the considerable advantage of direct derivation, the outlet also has the advantage that it is not visible to the user.

Die Bodenplatte wird man auf dem WC-Becken befestigen. Ihre Positionierung sollte zweckmäßig so erfolgen, dass die Leckage in das WC-Becken gelangen kann. Eine vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass der Auslass im Frontbereich der Bodenplatte angeordnet ist. Eine derartige Konstruktion gestattet es, dass sich lediglich ein geringer Teil der Bodenplatte über die Öffnung des WC-Beckens erstreckt, was neben dem Vorteil einer besseren Zugänglichkeit der WC-Beckenöffnung zu Reinigungszwecken auch den Vorteil einer stabilen und gleichzeitig kompakten Gesamtkonstruktion bedeutet.The base plate will be attached to the toilet bowl. It should be positioned appropriately so that the leakage can get into the toilet bowl. An advantageous embodiment of the invention is characterized in that the outlet is arranged in the front area of the base plate. Such a construction allows only a small portion of the floor panel to extend over the opening of the toilet bowl, which, in addition to the advantage of better accessibility of the toilet bowl opening for cleaning purposes, also means the advantage of a stable and at the same time compact overall construction.

Vorzugsweise weist der Kanal Seitenwände auf. Die Seitenwände können beispielsweise integral mit der Bodenplatte ausgebildet sein und von der Bodenplatte nach oben abgehen. Der Kanal ist vorteilhaft zumindest teilweise nach oben hin offen. Die erleichtert unter anderem eine gute Zugänglichkeit bei einer Inspektion und/oder Reinigung des WC-Aufsatzes.Preferably the channel has side walls. The side walls can, for example, be formed integrally with the base plate and extend upwards from the base plate. The channel is advantageously at least partially open at the top. Among other things, this facilitates good accessibility when inspecting and/or cleaning the toilet seat.

Eingangs wurde bereits angesprochen, dass es von Vorteil sein kann, die Wasserabsicherung im hinteren Bereich des WC-Aufsatzes bzw. dessen Bodenplatte anzuordnen. Insoweit wird es als vorteilhaft angesehen, wenn sich der Kanal von hinten nach vorne erstreckt. Vorzugsweise mündet er - in seitlicher Erstreckungsrichtung des WC-Aufsatzes gesehen - im mittleren Drittel des WC-Aufsatzes. Bei einer vorteilhaften Konstruktion ist die Düse im wesentlichen mittig angeordnet. Benachbart mündet der Kanal.It was already mentioned at the beginning that it can be advantageous to arrange the water protection in the rear area of the toilet seat or its base plate. In this regard, it is considered advantageous if the channel extends from the back to the front. It preferably opens out - as seen in the lateral extension direction of the toilet seat - in the middle third of the toilet seat. In an advantageous construction, the nozzle is arranged substantially centrally. The canal empties nearby.

Um sicherzustellen, dass die Leckage (oder Spritzwasser oder dergleichen) abgeleitet wird, ist eine vorteilhafte Ausführungsform der Erfindung dadurch gekennzeichnet, dass der Kanal nach vorne hin abfällt. Dadurch ist vorteilhaft sichergestellt, dass das Wasser nach vorne fließt und es nicht zu einem Wasserstau kommt, der unter anderem auch hygienische Nachteile haben könnte.In order to ensure that the leakage (or splashing water or the like) is discharged, an advantageous embodiment of the invention is characterized in that the channel slopes towards the front. This advantageously ensures that the water flows forward and water does not accumulate, which could also have hygienic disadvantages, among other things.

Der WC-Aufsatz kann so konstruiert sein, dass er eine Befestigungseinrichtung aufweist, mittels der er am WC-Becken festlegbar ist. Die Befestigungseinrichtung kann so ausgebildet sein, dass der WC-Aufsatz unmittelbar auf der WC-Keramik befestigt wird. Alternativ und bevorzugt wird auf dem WC-Becken eine Grundplatte montiert, und der WC-Aufsatz wird durch die Befestigungseinrichtung auf der Grundplatte montiert. Vorteilhafterweise ist vorgesehen, dass der Kanal die Befestigungseinrichtung überbrückt. Das Wasser kann also abgeleitet werden, ohne dass der Abfluss durch die Befestigungseinrichtung behindert wird.The toilet seat can be constructed in such a way that it has a fastening device by means of which it can be fixed to the toilet bowl. The fastening device can be designed in such a way that the toilet seat is fastened directly to the toilet ceramic. Alternatively and preferably, a base plate is mounted on the toilet bowl and the toilet seat is mounted on the base plate by the fastening device. It is advantageously provided that the channel bridges the fastening device. The water can therefore be drained off without the outflow being impeded by the fastening device.

In der Praxis sollte sichergestellt sein, dass sämtlicher Wasserverlust durch den Kanal aufgefangen wird. Hierzu wird vorgeschlagen, dass die Wasserabsicherung über dem Kanal angeordnet ist, und zwar vorteilhaft derart, dass Leckage von der Wasserabsicherung vorzugsweise unmittelbar nach unten in den Kanal abtropft. Insbesondere kann vorgesehen sein, dass die Wasserabsicherung vorzugsweise teilweise in den Kanal eingreift.In practice it should be ensured that all water loss is contained by the channel. To this end, it is proposed that the water safety device be arranged above the duct, advantageously in such a way that leakage from the water safety device preferably drips directly down into the duct. In particular, it can be provided that the water safeguard preferably partially engages in the channel.

Wie eingangs bereits dargelegt, bietet der Kanal die Möglichkeit einer (weitgehend) freien Positionierung der Wasserabsicherung in Bezug auf die Duscheinrichtung. Diese freie Positionierung kann zur Optimierung des Wirkungsgrades der Gesamtanordnung (geringe Leckage, gesteigerte Durchflussmenge) und zur Absicherung ggf. nicht im Trinkwasserbereich zugelassener Materialien am Wassereingang des WC-Aufsatzes genutzt werden. Ein weiterer wesentlicher Vorteil des Kanals besteht darüber hinaus darin, dass die Wasserabsicherung so platziert werden kann, dass zur Wartung nicht, wie im Stand der Technik, das Gehäuse der Wasserabsicherung und/oder der Deckel des WC-Aufsatzes geöffnet werden muss. Vielmehr ist es in Weiterbildung der Erfindung möglich, die Wartung von außen vorzunehmen. Hierzu weist der WC-Aufsatz erfindungsgemäß einen Deckel auf, in dem eine Wartungsöffnung ausgebildet ist, wobei die Wasserabsicherung vorteilhaft benachbart zu der Wartungsöffnung angeordnet ist. Die Wartungsöffnung kann mit einem Abdeckplättchen, einem Pfropfen oder dergleichen verschlossen sein.As already explained at the beginning, the channel offers the possibility of (largely) free positioning of the water safety device in relation to the shower facility. This free positioning can be used to optimize the efficiency of the overall arrangement (low leakage, increased flow rate) and to secure materials that may not be permitted in the drinking water area at the water inlet of the toilet seat. In addition, another significant advantage of the channel is that the water protection can be placed in such a way that for maintenance not, as in the prior art, the housing of the water protection and / or the lid of the toilet seat must be opened. Rather, it is possible in a further development of the invention to carry out the maintenance from the outside. For this purpose, according to the invention, the toilet seat has a cover in which a maintenance opening is formed, with the water safeguard advantageously being arranged adjacent to the maintenance opening. The maintenance opening can be closed with a cover plate, a plug or the like.

Als konstruktiv vorteilhaft wird ein WC-Aufsatz angesehen, bei dem auf der Bodenplatte die Duscheinrichtung, die Wasserabsicherung, der Kanal und vorzugsweise auch ein Ventil angeordnet sind, das mit der Wasserabsicherung in Leitungsverbindung steht. Sämtliche wichtigen Komponenten sind also mit der Bodenplatte verbunden, was insbesondere eine einfache Handhabbarkeit des Aufsatzes (zum Beispiel bei der Montage) schafft.A toilet attachment is considered to be structurally advantageous in which the shower device, the water safety device, the channel and preferably also a valve which is in line connection with the water safety device are arranged on the base plate. All important components are therefore connected to the base plate, which in particular makes the attachment easy to handle (e.g. during assembly).

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

The invention is explained in more detail below using a preferred exemplary embodiment in connection with the attached drawing. The drawing shows in:
figure 1
a perspective view of a toilet seat according to the invention in the open state;
figure 2
a perspective view of the toilet attachment figure 1 with lid; and
figure 3
a schematic representation of a mounting plate for attaching the toilet seat to a toilet bowl.

Figur 1 zeigt ein Ausführungsbeispiel eines erfindungsgemäßen WC-Aufsatzes. Der WC-Aufsatz weist eine Bodenplatte 1 auf, auf der ein Ventil 2, eine Duscheinrichtung 3 und eine Wasserabsicherung 4 angeordnet sind. Das Ventil 2, die Duscheinrichtung 3 und die Wasserabsicherung 4 sind über eine Leitung 5, die vorteilhaft aus mehreren Leitungsabschnitten besteht, miteinander verbunden. figure 1 shows an embodiment of a toilet seat according to the invention. The toilet seat has a base plate 1 on which a valve 2, a shower device 3 and a water fuse 4 are arranged. The valve 2, the shower device 3 and the water safety device 4 are connected to one another via a line 5, which advantageously consists of several line sections.

Das Ventil 2 weist einen Wasseranschluss 6 und einen Betätigungsknopf 7 auf. Der WC-Aufsatz wird über den Wasseranschluss 6 zur Wasserversorgung an eine (nicht gezeigte) Wasserleitung angeschlossen. Über den Betätigungsknopf 7 wird die Wassermenge geregelt, die aus der Duscheinrichtung austreten soll.The valve 2 has a water connection 6 and an actuating button 7 . The toilet seat is connected to a water pipe (not shown) via the water connection 6 for water supply. About the operating button 7, the amount of water is regulated, which should emerge from the shower device.

Die Duscheinrichtung 3 weist einen stationären Gehäuseabschnitt 8 und einen unter Wasserdruck ausfahrbaren Düsenabschnitt 9 auf, an dessen Ende sich eine Düse 10 befindet. Aus der Düse 10 tritt das Wasser zur Reinigung aus.The shower device 3 has a stationary housing section 8 and a nozzle section 9 which can be extended under water pressure and at the end of which there is a nozzle 10 . The water for cleaning emerges from the nozzle 10 .

Zwischen dem Ventil 2 und der Duscheinrichtung 3 ist die Wasserabsicherung 4 angeordnet. Die Wasserabsicherung 4 weist einen (nicht sichtbaren) Injektor auf, bei dem ein Wasserstrahl über einen freien Abschnitt gespritzt wird. Eine derartige Wasserabsicherung ist vorzugsweise horizontal angeordnet. Dies bedeutet, dass der Wasserstrahl horizontal über den freien Abschnitt geht. Bei einem Rücklaufen von Wasser ist durch den Freiraum eine Verschmutzung des Leitungswassers ausgeschlossen.The water safety device 4 is arranged between the valve 2 and the shower device 3 . The water safeguard 4 has an injector (not visible) in which a jet of water is sprayed over a free section. Such water protection is preferably horizontal arranged. This means that the water jet goes horizontally across the free section. If the water runs back, contamination of the tap water is prevented by the free space.

Im Betrieb kann bei der Wasserabsicherung 4 Leckage anfallen. Diese Leckage (oder Spritzwasser oder dergleichen) wird durch einen Kanal 11 in das WC-Becken abgeleitet. Hierzu weist die Bodenplatte 1 eine Öffnung 12 auf, in der der Kanal 11 mündet. Durch die Öffnung 12 gelangt die Leckage in das WC-Becken. Die Öffnung ist im mittleren Drittel der Breite der Bodenplatte angeordnet. Hier weist die Öffnung des WC-Beckens ihre maximale Erstreckung auf.During operation, the water protection 4 leaks can occur. This leakage (or splashing water or the like) is discharged through a channel 11 into the toilet bowl. For this purpose, the base plate 1 has an opening 12 into which the channel 11 opens. The leakage enters the toilet bowl through the opening 12 . The opening is located in the middle third of the width of the base plate. Here the opening of the toilet bowl has its maximum extension.

Der Kanal 11 weist Seitenwände 13 auf und ist bevorzugt integral mit der Bodenplatte 1 ausgebildet. Der Kanalboden 14 weist zur Öffnung 12 hin ein Gefälle auf. Eventuelles Wasser wird also sicher abgeleitet ohne die Gefahr von Standwasser.The channel 11 has side walls 13 and is preferably formed integrally with the base plate 1 . The channel bottom 14 has a gradient towards the opening 12 . Any water is therefore safely drained away without the risk of standing water.

Die Wasserabsicherung 4 weist einen Abstandshalter auf, der vorzugsweise als Gitter 15 ausgebildet sein kann, das Spritzwasser unmittelbar in den Kanal 11 ableitet. Der Abstandshalter weist eine Höhe (maximale Erstreckung) von mindestens 2 cm auf. Dies gewährleistet besonders vorteilhaft die Einhaltung trinkwasserspezifischer Vorgaben. Die Wasserabsicherung greift (vorliegend mit dem Gitter 15) in den Kanal 11 ein und schafft damit ein sicheres Auffangen sämtlichen Spritzwassers.The water safeguard 4 has a spacer, which can preferably be designed as a grid 15 that drains spray water directly into the channel 11 . The spacer has a height (maximum extent) of at least 2 cm. This particularly advantageously ensures compliance with drinking water-specific specifications. The water protection intervenes (here with the grid 15) in the channel 11 and thus creates a safe collection of all splashing water.

Der WC-Aufsatz ist über eine Befestigungseinrichtung an dem WC-Becken befestigbar. Hierzu weist der WC-Aufsatz eine Betätigungseinrichtung 16, die in Eingriff mit einer auf dem WC-Becken vormontierten Montageplatte 17 (siehe Figur 3) bringbar ist. Der Kanal 11 überspannt die Betätigungseinrichtung 16.The toilet seat can be attached to the toilet bowl via a fastening device. For this purpose, the toilet seat has an actuating device 16, which engages with a mounting plate 17 (see Fig figure 3 ) can be brought. The channel 11 spans the actuating device 16.

Im Übrigen sei anhand des Koordinatensystems noch einmal verdeutlicht, was unter den Ortsangaben Oben (O), Unten (U), Vorne (V) und Hinten (bzw. Rückseite) (H) verstanden wird. Diese orientieren sich an der üblichen Bezeichnung anhand eines WC's. Dies gilt auch für die Bezugnahmen auf die Duscheinrichtung. Aus Figur 1 wird auch deutlich, dass die Wasserabsicherung 4 im hinteren Bereich der Bodenplatte 1 angeordnet ist und dass der Kanal 11 von hinten nach vorne verläuft.Incidentally, the coordinate system should be used to clarify what is meant by the location information top (O), bottom (U), front (V) and back (or back) (H). These are based on the usual designation based on a toilet. This also applies to the references to the shower facility. Out of figure 1 it is also clear that the water protection 4 is arranged in the rear area of the base plate 1 and that the channel 11 runs from the back to the front.

Figur 2 zeigt den WC-Aufsatz nach Figur 1 mit einem Gehäusedeckel 18. Der WC-Aufsatz weist ferner zwei Drehzapfen 19, 20 auf, auf denen ein WC-Sitz schwenkbar gelagert wird. Die Drehzapfen sind stationär gehalten. In dem Gehäuse ist eine seitliche Öffnung 21 ausgebildet. Diese Öffnung 21 fluchtet mit der Wasserabsicherung 4. Durch diese Maßnahme ist die Wasserabsicherung 4 durch die Öffnung 21 beispielsweise zu Wartungszwecken zugänglich, ohne dass der Deckel 18 abgenommen werden muss. figure 2 shows the toilet seat figure 1 with a housing cover 18. The toilet seat also has two pivots 19, 20 on which a toilet seat is pivotally mounted. The trunnions are held stationary. A lateral opening 21 is formed in the housing. This opening 21 is aligned with the water fuse 4. This measure makes the water fuse 4 accessible through the opening 21, for example for maintenance purposes, without the cover 18 having to be removed.

Figur 3 zeigt eine Montageplatte 17, die auf einem WC-Becken vormontiert werden kann. Die Montageplatte 17 weist zwei Langlöcher 22 auf, durch die hindurch (nicht gezeigte) Schrauben oder Gewindezapfen greifen, mit denen die Montageplatte an dem WC-Becken befestigt werden. Der WC-Aufsatz wird auf die Montageplatte 17 aufgeschoben. Zur Verankerung der Bodenplatte 1 weist die Montageplatte 17 schienenartige Stege 23 auf, die in entsprechende Ausnehmungen der Bodenplatte eingreifen. figure 3 shows a mounting plate 17 that can be pre-assembled on a toilet bowl. The mounting plate 17 has two elongated holes 22 through which (not shown) screws or threaded pins engage with which the Mounting plate to be attached to the toilet bowl. The toilet seat is pushed onto the mounting plate 17. For anchoring the base plate 1, the mounting plate 17 has rail-like webs 23 which engage in corresponding recesses in the base plate.
