Eine Zu- und Überlaufarmatur dieser Art ist aus dem Gebrauchsmuster DE 93 01 156 U1 bekannt.An inlet and overflow fitting of this kind is from the utility model DE 93 01 156 U1 known.

Ferner ist aus der DE 42 26 685 C2 eine Überlaufarmatur für Badewannen bekannt, die eine wahlweise Einstellung des Überlaufniveaus erlaubt. Die bekannte Überlaufarmatur weist einen an einer Durchgangsöffnung der Wannenwandung festlegbaren Rohranschluß auf, dessen Mündung in den Wanneninnenraum ausmündet. Die Mündung ist mit einer Abdeckrosette abgedeckt, die mit einer radial verlaufenden kanalartigen Verlängerung versehen ist, welche unter der Abdeckrosette mit einer Durchtrittsöffnung ausmündet, die seitlich zur Achse der Mündung des Rohranschlusses beabstandet ist. Die Abdeckrosette ist dabei gegenüber der Mündung des Rohranschlusses abdichtbar ausgebildet und zur Einstellung unterschiedlicher Füllstände bewegbar mit dem Rohranschluß verbunden. Der Rohranschluß kann dabei auch eine Verstellmechanik aufweisen, die mit dem Bodenventil der Badewanne in Verbindung steht, wobei die Abdeckrosette dann zugleich als Betätigungselement für das Bodenventil ausgebildet ist. In diesem Fall ist die Abdeckrosette in axialer Richtung, nämlich in Richtung der Achse der Mündung des Rohranschlusses hin- und herbewegbar, um das Überlaufniveau (Füllniveau) einzustellen. Diese Ausführungsform erlaubt jedoch praktisch nur die Einstellung von zwei unterschiedlichen Füllständen, nämlich eines "normalen" Überlaufniveaus, das bei von der Wanneninnenwandung abgezogener Abdeckrosette durch die Unterkante der Mündung des Rohranschlusses definiert ist, und eines erhöhten Überlaufniveaus, welches bei Anlage der Abdeckrosette an der Wanneninnenwandung durch die Höhe der Durchtrittsöffnung der Abdeckrosette definiert ist.Furthermore, from the DE 42 26 685 C2 an overflow fitting for baths is known, which allows an optional adjustment of the overflow level. The known overflow fitting has a fixable at a passage opening of the tub wall pipe connection, the mouth of which opens into the tub interior. The mouth is covered with a cover rosette, which is provided with a radially extending channel-like extension, which opens below the covering rosette with a passage opening which is laterally spaced from the axis of the mouth of the pipe connection. The cover rosette is opposite the mouth of the pipe connection formed sealable and movably connected to the setting of different levels with the pipe connection. The pipe connection can also have an adjustment, which is in communication with the bottom valve of the bathtub, wherein the cover rosette is then formed at the same time as an actuator for the bottom valve. In this case, the cover rosette in the axial direction, namely in the direction of the axis of the mouth of the pipe connection back and forth to adjust the overflow level (filling level). This embodiment, however, allows practically only the setting of two different levels, namely a "normal" overflow level, which is defined by the lower edge of the mouth of the pipe connection deducted from the tub inner wall, and an increased overflow level, which when planting the cover rosette on the tub inner wall is defined by the height of the passage opening of the covering rosette.

Insbesondere liegt der Erfindung die Aufgabe zugrunde, eine solche multifunktionale Überlaufarmatur zu schaffen, welche auch ohne Vergrößerung des üblichen Durchmessers der Durchgangsöffnung der Wannenwandung die geforderte bzw. normierte Überlaufleistung erbringt. Darüber hinaus soll die Überlaufarmatur vorzugsweise eine stufenlose Einstellung des Überlaufniveaus zwischen einem unteren und einem oberen Füllstand erlauben.The present invention has for its object to provide an overflow fitting for bathtubs, which in addition to the overflow function provides an actuation function for the drain valve of the bathtub is provided with an integrated water inlet and also allows an optional adjustment of the overflow level. In particular, the invention has for its object to provide such a multifunctional overflow fitting, which provides the required or normalized overflow performance without increasing the usual diameter of the passage opening of the tub wall. In addition, the overflow fitting should preferably allow a continuous adjustment of the overflow level between a lower and an upper level.

Diese Aufgabe wird durch eine Zu- und Überlaufarmatur mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a supply and overflow fitting with the features of claim 1.

Die erfindungsgemäße Zu- und Überlaufarmatur ist dadurch gekennzeichnet, dass auf dem Zulaufteil ein Stellelement zur Einstellung des Überlaufniveaus der Badewanne drehbar gehalten ist, wobei das Stellelement und das Zulaufteil zusammen einen Abschnitt eines innerhalb der Badewanne angeordneten Überlaufkanals bilden, an den sich ein zweiter, im zulaufteil ausgebildeter Überlaufkanalabschnitt anschließt, der an dem Überlaufkanal des Überlaufkörpers angeschlossen ist.The inlet and overflow fitting according to the invention is characterized in that on the inlet part an adjusting element for adjusting the overflow level of the bathtub is rotatably supported, wherein the control element and the inlet part together form a portion of an overflow channel disposed within the bathtub, to which a second, im zulaufteil trained overflow channel section connects, which is connected to the overflow channel of the overflow body.

In der erfindungsgemäßen Zu- und Überlaufarmatur sind somit die vier Funktionen:

  • Überlauffunktion,
  • Betätigungsfunktion für das Ablaufventil,
  • Füllniveau-Einstellfunktion und
  • Wasserzulauffunktion
zusammen verwirklicht.In the inlet and overflow fitting according to the invention thus the four functions are:
  • Overflow,
  • Actuating function for the drain valve,
  • Fill level adjustment function and
  • Water supply function
realized together.

Versuche haben gezeigt, dass sich mit der erfindungsgemäßen Zu- und Überlaufarmatur, die für die übliche Dimensionierung der Durchgangsöffnung der Wannenwandung ausgelegt ist, die geforderte bzw. normierte Überlaufleistung zuverlässig erzielen lässt. Zudem erlaubt die erfindungsgemäße Zu- und Überlaufarmatur eine stufenlose Einstellung des Überlaufniveaus zwischen einem unteren und einem oberen Füllstand.Experiments have shown that can be reliably achieved with the inlet and overflow fitting according to the invention, which is designed for the usual dimensioning of the passage opening of the tub wall, the required or normalized overflow performance. In addition, the inlet and overflow fitting according to the invention allows a continuous adjustment of the overflow level between a lower and an upper level.

In einer bevorzugten Ausgestaltung der erfindungsgemäßen zu- und Überlaufgarnitur ist vorgesehen, dass das Stellelement einen gekröpften, im wesentlichen radial abstehenden Griff aufweist, dem zwei an dem Zulaufteil ausgebildete Drehanschläge zugeordnet sind. Mit dieser Ausgestaltung lässt sich bei komfortabler Bedienbarkeit eine kompakte Bauweise der Armatur erreichen. Der eine Drehanschlag ist dabei vorzugsweise einem niedrigen Überlaufniveau zugeordnet, während der andere Drehanschlag für das maximale Überlaufniveau steht.In a preferred embodiment of the inlet and overflow fitting according to the invention it is provided that the Control element has a cranked, substantially radially projecting handle, which are associated with two formed on the inlet part rotational stops. With this configuration, a compact design of the valve can be achieved with comfortable operation. The one rotation stop is preferably assigned to a low overflow level, while the other rotation stop is for the maximum overflow level.

Eine weitere bevorzugte Ausgestaltung der erfindungsgemäßen Zu- und Überlaufgarnitur besteht darin, dass das Zulaufteil einen inneren, hülsenförmigen Abschnitt und ein äußeres, ringförmiges Befestigungsstück aufweist, wobei der hülsenförmige Abschnitt und das Befestigungsstück durch Stege miteinander einstückig verbunden sind. Hierdurch lässt sich bei den begrenzten Dimensionen des Zulaufteils ein für einen zuverlässigen Überlauf ausreichend großer Überlaufkanalquerschnitt im Zulaufteil realisieren.A further preferred embodiment of the inlet and overflow fitting according to the invention is that the inlet part has an inner, sleeve-shaped portion and an outer, annular attachment piece, wherein the sleeve-shaped portion and the attachment piece are integrally connected by webs. As a result, with the limited dimensions of the inlet part, it is possible to realize an overflow channel cross section in the inlet part that is sufficiently large for a reliable overflow.

Bevorzugt ist auch eine Ausgestaltung, bei der in der Außenseite des Befestigungsstückes eine Befestigungsnut ausgebildet ist, in welche ein an dem Griff des Stellelements ausgebildeter Vorsprung eingreift, wobei der Vorsprung entlang der Befestigungsnut verschiebbar ist. Hierdurch kann auf einfache Weise eine zuverlässige Halterung des Stellelements an dem Befestigungsstück erreicht werden. Anstelle einer solchen Befestigungsnut kann jedoch auch ein entsprechender Hinterschnitt vorgesehen werden.Also preferred is an embodiment in which in the outer side of the attachment piece, a fastening groove is formed, in which engages a formed on the handle of the actuating element projection, wherein the projection along the fastening groove is displaceable. In this way, a reliable mounting of the actuating element on the attachment piece can be achieved in a simple manner. However, instead of such a fastening groove, a corresponding undercut may also be provided.

Für eine ästhetische Formgestaltung der Zu- und Überlaufgarnitur ist es günstig, wenn nach einer weiteren bevorzugten Ausgestaltung dem Befestigungsstück eine ringförmige Abdeckung zugeordnet ist, wobei die Abdeckung durch an ihrer Innenseite angeformte Rastelemente an Befestigungselementen des Befestigungsstück befestigt werden kann. Der Außendurchmesser der ringförmigen Abdeckung entspricht dabei vorzugsweise etwa dem Außendurchmesser des im wesentlichen kreisscheibenförmig gestalteten Drehgriffs.For an aesthetic shape of the inlet and overflow fitting, it is advantageous if, according to a further preferred embodiment, the attachment piece a annular cover is assigned, wherein the cover can be secured by integrally formed on its inner side locking elements to fasteners of the attachment piece. The outer diameter of the annular cover preferably corresponds approximately to the outer diameter of the essentially circular disk-shaped rotary handle.

Zur Sicherstellung einer ausreichend hohen Überlaufleistung ist es ferner günstig, wenn nach einer weiteren bevorzugten Ausgestaltung zwischen dem Drehgriff und der ringförmigen Abdeckung ein Spalt vorgesehen wird, dessen Breite im Bereich von ca. 1 bis 5 mm liegt.To ensure a sufficiently high overflow performance, it is also advantageous if, according to a further preferred embodiment, a gap is provided between the rotary handle and the annular cover, whose width is in the range of approximately 1 to 5 mm.

Für eine kompakte Ausführung der erfindungsgemäßen Zu- und Überlaufgarnitur ist es ferner günstig, wenn das Zulaufteil einen schlitzförmig ausgebildeten Wassereinlaufkanal bzw. flachen Wassereinlaufstutzen aufweist, der sich im wesentlichen rechtwinklig oder quer zur Drehachse des Drehgriffs erstreckt.For a compact design of the inlet and overflow fitting according to the invention, it is also advantageous if the inlet part has a slot-shaped water inlet channel or flat water inlet nozzle, which extends substantially perpendicular or transverse to the axis of rotation of the rotary handle.

The overflow body 2 has an overflow channel 5, a water connection 6 and a cylindrical holder 7 for an end portion of a Bowden cable (not shown) for actuating a drain valve 8 (bottom valve). The overflow channel 5 has a nozzle-shaped connection portion, on which a connectable to the outlet 9 of the bathtub 3 overflow pipe 10 can be inserted.

Die Überlaufarmatur 1 umfasst des weiteren ein Antriebsteil für ein Getriebeteil zum Öffnen und Schließen des Ablaufventils 8 der Badewanne 3, das mittels eines Drehgriffs 11 betätigt werden kann. Der Überlaufkörper 2 ist mit einer Lagerhülse 12 versehen, die sich durch die Durchgangsöffnung in die Badewanne erstreckt. In der Lagerhülse 12 ist ein Ritzel 13 und eine durch den Drehgriff betätigbare Mitnehmerwelle 14 gelagert. Das Ritzel 13 wird mit einem Bowdenzug gekoppelt, über den die Drehbewegung des Drehgriffs 11 auf einen das Ablaufventil 8 betätigenden Hebe- und Senkmechanismus übertragen wird.The overflow fitting 1 further comprises a drive part for a transmission part for opening and closing the drain valve 8 of the bath 3, which can be actuated by means of a rotary handle 11. The overflow body 2 is provided with a bearing sleeve 12 which extends through the passage opening in the bathtub. In the bearing sleeve 12 is a pinion 13 and a through the Rotary handle operable driver shaft 14 stored. The pinion 13 is coupled to a Bowden cable, via which the rotational movement of the rotary handle 11 is transmitted to the drain valve 8 actuated lifting and lowering mechanism.

Zwischen dem Drehgriff 11 und der Badewannenrückwand ist ein Zulaufteil 15 angeordnet, das mit einem inneren, hülsenförmigen Abschnitt 15.1 auf der Lagerhülse 12 festgelegt ist. An seiner der Badewanneninnenfläche zugewandten Seite ist das Zulaufteil 15 mit in die Durchgangsöffnung der Badewanne 3 vorstehenden Zentrierstiften 15.2 versehen.Between the rotary handle 11 and the bath rear wall, an inlet part 15 is arranged, which is fixed with an inner, sleeve-shaped portion 15.1 on the bearing sleeve 12. On its side facing the bathtub interior surface, the inlet part 15 is provided with centering pins 15.2 projecting into the passage opening of the bathtub 3.

Der hülsenförmige Abschnitt 15.1 des Zulaufteils 15 weist innen einen umlaufenden Vorsprung 15.3 auf, der mit einem ringförmig umlaufenden Absatz zur Aufnahme eines Dichtringes 16 versehen ist, welcher dichtend an der Außenseite einer die Mitnehmerwelle 14 umgebenden Hülse 17 anliegt. Der Vorsprung 15.3 und eine Zwischenhülse 18 bilden somit praktisch eine Ringnut. Anstelle des ringförmig umlaufenden Absatzes kann in dem Vorsprung 15.3 auch eine Ringnut zur Aufnahme des Dichtringes 16 vorgesehen werden. In der Wandung der Lagerhülse 12 ist ein mittlerer Ringspalt 12.1 ausgebildet, über den ein Wasserzulauf vom Wasseranschluß 6 des Überlaufkörpers 2 zu einem in die Wanne mündenden Wassereinlaufkanal 15.4 erfolgen kann. Der Wassereinlaufkanal 15.4 ist flach und schlitzförmig ausgebildet und erstreckt sich im wesentlichen rechtwinklig zur Drehachse des Drehgriffs 11.The sleeve-shaped portion 15.1 of the inlet part 15 has on the inside a circumferential projection 15.3 which is provided with an annular peripheral shoulder for receiving a sealing ring 16 which sealingly bears against the outside of a sleeve 17 surrounding the drive shaft 17. The projection 15.3 and an intermediate sleeve 18 thus form an annular groove practically. Instead of the annular peripheral shoulder can be provided in the projection 15.3 and an annular groove for receiving the sealing ring 16. In the wall of the bearing sleeve 12, a middle annular gap 12.1 is formed, via which a water inlet from the water connection 6 of the overflow body 2 can be made to a water inlet channel 15.4 opening into the tub.

The heads of the screws or threaded pins 19 are recessed in the sleeve-shaped portion 15.1 of the inlet part 15. The sleeve-shaped portion 15.1 has for this purpose bores or the like, which are aligned with the threaded bores of the intermediate sleeve 18 and can be brought into coincidence.

Der hülsenförmige Abschnitt 15.1 des Zulaufteils 15 ist außen mit einem davon radial beabstandeten, kreisringförmigen Befestigungsstück 15.6 versehen. Das Befestigungsstück 15.6 und der hülsenförmige Abschnitt 15.1 sind durch über den Umfang des hülsenförmigen Abschnittes 15.1 verteilt angeordnete Stege 15.7 einstückig miteinander verbunden. Zudem sind das Befestigungsstück 15.6 und der hülsenförmige Abschnitt 15.1 durch den wassereinlaufkanal 15.4 verbunden, der das kreisringförmige Befestigungsstück 15.6 durchdringt.The sleeve-shaped portion 15.1 of the inlet part 15 is provided on the outside with one of them radially spaced annular fastening piece 15.6. The Fastening piece 15.6 and the sleeve-shaped portion 15.1 are integrally connected by distributed over the circumference of the sleeve-shaped portion 15.1 arranged webs 15.7. In addition, the attachment piece 15.6 and the sleeve-shaped portion 15.1 are connected by the water inlet channel 15.4, which penetrates the annular attachment piece 15.6.

Auf dem hülsenförmigen Abschnitt 15.1 des Zulaufteils 15 ist ein Stellelement 20 zur Einstellung des Überlaufniveaus der Badewanne 3 gehalten, das relativ zu dem Zulaufteil 15 verdreht bzw. verschwenkt werden kann.On the sleeve-shaped portion 15.1 of the inlet part 15, an adjusting element 20 is held for adjusting the overflow level of the bath 3, which can be rotated or pivoted relative to the inlet part 15.

Das Stellelement 20 und das Zulauf teil 15 bilden zusammen einen Abschnitt 5.1 eines innerhalb der Badewanne 3 angeordneten Überlaufkanals, an den sich ein zweiter, im Zulauf teil 15 ausgebildeter Überlaufkanalabschnitt 5.2 anschließt, der schließlich am Überlaufkanal 5 des Überlaufkörpers 2 angeschlossen ist.The actuator 20 and the inlet part 15 together form a section 5.1 of a disposed inside the bathtub 3 overflow channel, to which a second, in the inlet part 15 trained overflow channel section 5.2 connects, which is finally connected to the overflow channel 5 of the overflow body 2.

Das Stellelement 20 besitzt einen U-förmigen Überlaufkanal 20.1, der einen inneren, ringförmigen, an dem hülsenförmigen Abschnitt 15.1 des Zulauf teils 15 anliegenden Wandungsabschnitt 20.2, einen dem Drehgriff 11 zugewandten im wesentlichen U-förmig ausgebildeten Wandungsabschnitt 20.3 und einen äußeren Wandungsabschnitt 20.4 aufweist, wobei letzterer einen halbkreisringförmigen Teilabschnitt 20.41 und zwei sich daran anschließende, parallel zueinander verlaufende Teilabschnitte 20.42, 20.43 umfasst.The adjusting element 20 has a U-shaped overflow channel 20.1, which has an inner, annular, on the sleeve-shaped portion 15.1 of the inlet part 15 adjacent wall portion 20.2, the rotary handle 11 facing substantially U-shaped wall portion 20.3 and an outer wall portion 20.4, the latter comprising a semicircular portion 20.41 and two adjoining, mutually parallel sections 20.42, 20.43.

Die Mantelfläche des hülsenförmigen Abschnitts 15.1 ist mit einer Ringnut zur Aufnahme eines Dichtringes 22 versehen, an dem wandungsabschnitt 20.2 des Stellelements 20 anliegt.The lateral surface of the sleeve-shaped portion 15.1 is provided with an annular groove for receiving a sealing ring 22nd provided on the wall portion 20.2 of the actuating element 20 abuts.

An den halbkreisringförmigen Teilabschnitt 20.41 schließt sich in Richtung des Überlaufkörpers 2 ein kreisringförmiger Teilabschnitt 20.44 einstückig an. Der kreisringförmige Abschnitt 20.44 greift in das ringförmige Befestigungsstück 15.6 des Zulaufteils 15 ein. An seiner Außenseite ist eine Ringnut 20.5 zur Aufnahme eines an der Innenseite des Befestigungsstückes 15.6 anliegenden Dichtringes ausgebildet.On the semicircular portion 20.41 connects in the direction of the overflow body 2, an annular portion 20.44 in one piece. The annular portion 20.44 engages in the annular attachment piece 15.6 of the inlet part 15 a. On its outer side an annular groove 20.5 is formed for receiving a voltage applied to the inside of the attachment piece 15.6 sealing ring.

Das Stellelement 20 weist ferner einen von dem kreisringförmigen Abschnitt 20.44 im wesentlichen radial abstehenden, gekröpften Griff 20.6 auf, dem zwei an dem Zulaufteil (Befestigungsstück) ausgebildete Drehanschläge 15.81, 15.82 zugeordnet sind. Der S-förmig gekröpfte Griff 20.6 ist mittig zwischen den parallel zueinander verlaufenden Wandungsabschnitten 20.42, 20.43 des Stellelements 20 angeordnet. Er liegt somit mittig zur Überlauföffnung 20.7 des Stellelements 20. Außen- bzw. oberseitig ist an dem Griff 20.6 ein Mittelsteg 20.8 angeformt, welcher der Erhöhung der Biegesteifigkeit dient.The actuator 20 further includes a of the annular portion 20.44 substantially radially projecting, cranked handle 20.6, the two at the inlet part (fixing piece) formed rotational stops 15.81, 15.82 are assigned. The S-shaped cranked handle 20.6 is arranged centrally between the mutually parallel wall sections 20.42, 20.43 of the actuating element 20. It is thus located at the center of the overflow opening 20.7 of the actuating element 20. On the outer side or on the upper side, a central web 20.8 is formed on the handle 20.6, which serves to increase the flexural rigidity.

An dem Griff 20.6 ist ferner eine Haltenase 20.9 angeformt. Dieser unterseitig angeordnete Vorsprung 20.9 greift in eine Befestigungsnut 15.9 ein, die in der Mantelfläche des Befestigungsstückes 15.6 zwischen den Drehanschlägen 15.81, 15.82 ausgebildet ist. Zur Anordnung der Haltenase 20.9 in der Befestigungsnut wird der Griff 20.6 ein wenig in Richtung der Überlauföffnung 20.7 gebogen bzw. gedrückt. Nach Wegfall dieser Krafteinwirkung stellt sich der Griff 20.6 elastisch zurück, so dass die Haltenase 20.9 in die Befestigungsnut 15.9 eingreift. Bei einer Drehung (Verschwenkung) des Stellelements 20 bewegt sich die Haltenase 20.9 entlang der Befestigungsnut 15.9, die in einer rechtwinklig zur Drehachse verlaufenden Ebene liegt.On the handle 20.6 also a retaining lug 20.9 is formed. This lower side projection 20.9 engages in a mounting groove 15.9, which is formed in the lateral surface of the attachment piece 15.6 between the rotational stops 15.81, 15.82. To arrange the retaining lug 20.9 in the fastening groove, the handle 20.6 is bent or pressed slightly in the direction of the overflow opening 20.7. After elimination of this force, the handle is 20.6 elastic back, so that the retaining lug 20.9 engages in the mounting groove 15.9. Upon rotation (pivoting) of the actuating element 20, the retaining lug 20.9 moves along the fastening groove 15.9, which lies in a plane perpendicular to the axis of rotation.

Dem Befestigungsstück 15.6 ist eine kreisringförmige Abdeckung 21 zugeordnet, die durch an ihrer Innenseite angeformte Rastelemente 21.1, 21.2 an Befestigungselementen 15.83, 15.84 des Befestigungsstückes 15.6 befestigbar ist. In dem dargestellten Ausführungsbeispiel bestehen die Rastelemente 21.1, 21.2 aus Halteclipsen, die mit stegförmig ausgebildeten Befestigungselementen 15.83, 15.84 des Befestigungsstückes 15.6 verrastbar sind.The fastening piece 15.6 is associated with an annular cover 21, which is fastened by integrally formed on its inside locking elements 21.1, 21.2 to fasteners 15.83, 15.84 of the attachment piece 15.6. In the illustrated embodiment, the locking elements 21.1, 21.2 consist of retaining clips, which can be latched with web-shaped fastening elements 15.83, 15.84 of the fastening piece 15.6.

Es ist zu erkennen, dass die kreisringförmige Abdeckung 21 an ihrer dem Überlaufkörper 2 zugewandten Stirnseite eine Aussparung 21.3 zur Durchführung bzw. Aufnahme des Einlaufkanals 15.4 aufweist. Zudem ist an der dem Drehgriff 11 zugewandten Stirnseite eine Aussparung 21.4 vorgesehen, die bei steigendem Wasserstand in der Badewanne 3 einen Zufluß von Wasser in die Überlauföffnung 20.7 sicherstellt. Ferner ist zu erkennen, dass zwischen dem Drehgriff 11 und der kreisringförmigen Abdeckung 21 ein Spalt S vorgesehen ist. Die Breite dieses Spaltes liegt im Bereich von 1 bis 5 mm, insbesondere im Bereich von 1,5 bis 2,5 mm.It can be seen that the annular cover 21 on its the overflow body 2 facing end has a recess 21.3 for carrying or receiving the inlet channel 15.4. In addition, a recess 21.4 is provided on the rotary handle 11 facing the end face, which ensures an inflow of water into the overflow opening 20.7 with increasing water level in the bath 3. Furthermore, it can be seen that between the rotary handle 11 and the annular cover 21, a gap S is provided. The width of this gap is in the range of 1 to 5 mm, in particular in the range of 1.5 to 2.5 mm.

Der Überlaufkörper 2, das Zulaufteil 15, das Stellelement 20 und die Abdeckung 21 können vorzugsweise als Spritzgießteile aus Kunststoff hergestellt werden.The overflow body 2, the inlet part 15, the adjusting element 20 and the cover 21 may preferably be made of plastic as injection molded parts.

In Fig. 17 ist eine Variante des Zulaufteils 15 dargestellt. Es ist zu erkennen, dass hier anstelle der Befestigungsnut 15.9 ein Hinterschnitt 15.10 am Zulaufteil 15 ausgebildet ist. Der Hinterschnitt 15.10 ist ebenfalls in der Mantelfläche des Befestigungsstückes 15.6 zwischen den Drehanschlägen 15.81, 15.82 ausgebildet und dient der Befestigung des Stellelements 20, dessen Vorsprung (Haltenase) 20.9 den Hinterschnitt hintergreift. Bei einer Drehung (Verschwenkung) des Stellelements 20 bewegt sich die Haltenase 20.9 entlang des Hinterschnitts 15.10, der in einer rechtwinklig zur Drehachse des Stellelements verlaufenden Ebene liegt.In Fig. 17 a variant of the inlet part 15 is shown. It can be seen that instead of the fastening groove 15.9, an undercut 15.10 is formed on the inlet part 15. The undercut 15.10 is also formed in the lateral surface of the attachment piece 15.6 between the rotational stops 15.81, 15.82 and serves to fasten the actuating element 20, the projection (retaining lug) 20.9 engages behind the undercut. Upon rotation (pivoting) of the actuating element 20, the retaining lug 20.9 moves along the undercut 15.10, which lies in a direction perpendicular to the axis of rotation of the actuating element extending plane.
