Description

Die Erfindung betrifft eine Zu- und Überlaufarmatur für eine Badewanne gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a supply and overflow fitting for a bathtub according to the preamble of claim 1.

Zu- und Überlaufarmaturen für Badewannen, in denen zusätzlich zu der Überlauffunktion und der Betätigungsfunktion für das Ablaufventil der Badewanne auch eine Wasserzulauffunktion integriert ist, sind bekannt (siehe z.B. DE 93 01 156 U1 ).Intake and overflow fittings for bathtubs, in which in addition to the overflow function and the actuation function for the drain valve of the bathtub and a water supply function is integrated, are known (see, eg DE 93 01 156 U1 ).

Ferner ist aus der DE 42 26 685 C2 eine Überlaufarmatur für eine Badewanne 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 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) der Badewanne einzustellen. Diese Überlaufarmatur enthält jedoch keinen Wasserzulauf. Ferner ist bei dieser Überlaufarmaturunbefriedigend, dass sich der nach einer gewissen Gebrauchsdauer der Armatur verschmutzende Einlaufbereich des Überlaufs im Sichtbereich der Armatur befindet.Furthermore, from the DE 42 26 685 C2 an overflow fitting for a bath known, which allows an optional adjustment of the overflow level. The known overflow fitting has a pipe connection which can be fixed to a passage opening of the tub wall and whose mouth 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 covering rosette is designed to be sealable with respect to the mouth of the pipe connection and movably connected to the pipe connection for setting different levels. The pipe connection can also have an adjusting mechanism, which communicates with the bottom valve of the bathtub, wherein the cover rosette is then also formed as an actuating element 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) of the bathtub. However, this overflow fitting contains no water supply. Furthermore, with this overflow fitting, it is unsatisfactory that the inlet region of the overflow contaminating after a certain period of use of the fitting is within the field of view of the fitting.

Aus der auf die Anmelderin zurückgehenden EP 1793 052 A2 ist eine Zu- und Überlaufarmatur für eine Badewanne bekannt, in der vier Funktionen integriert sind, nämlich eine Überlauffunktion, eine Betätigungsfunktion für das Ablaufventil, eine Füllniveau-Einstellfunktion und eine Wasserzulauffunktion. Der Überlaufkörper dieser bekannten Zu- und Überlaufarmatur weist eine sich durch die Durchgangsöffnung der Wannenwandung in die Badewanne erstreckende Lagerhülse für eine durch den Drehgriff betätigbare Mitnehmerwelle auf. Zwischen dem Drehgriff und der Badewannenrückseite ist ein auf der Lagerhülse festlegbares Zulaufteil angeordnet. Auf dem Zulaufteil ist ein Stellelement zur Einstellung des Überlaufniveaus der Badewanne drehbar gehalten, 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 dann schließlich an dem Überlaufkanal des Überlaufkörpers angeschlossen ist. Das Stellelement zur Einstellung des Überlaufniveaus ist dabei ein separat gefertigtes Bedienelement. Dieses Stellelement verursacht ein relativ großes Aufbaumaß, d.h. die Zu- und Überlaufarmatur steht relativ weit von der Wannenwandung vor, um die erforderliche Überlaufleistung sicherzustellen.From the date of the applicant EP 1793 052 A2 For example, there is known a bath inlet and overflow fitting incorporating four functions, an overflow function, an outlet valve actuation function, a fill level adjustment function, and a water inlet function. The overflow body of this known inlet and overflow fitting has a through the passage opening of the tub wall extending into the bathtub bearing sleeve for an actuatable by the rotary handle driver shaft. Between the rotary handle and the bath rear side a fixable on the bearing sleeve inlet part is arranged. On the inlet part, an adjusting element for adjusting the overflow level of the bathtub is rotatably supported, wherein the actuating element and the inlet part together form a portion of an overflow channel disposed within the bathtub, followed by a second, formed in the inlet part overflow channel section, which then finally to the overflow channel the overflow body is connected. The adjusting element for setting the overflow level is a separately manufactured operating element. This actuator causes a relatively large construction dimension, ie, the inlet and overflow fitting is relatively far from the tub wall to ensure the required overflow performance.

Davon ausgehend lag der vorliegenden Erfindung die Aufgabe zugrunde, eine Zu- und Überlaufarmatur für eine Badewanne zu schaffen, welche die vier genannten Funktionen der aus der EP 1 793 052 A2 bekannten Zu- und Überlaufarmatur bietet, den verschmutzenden Einlaufbereich des Überlaufs verdeckt, aus einer möglichst geringen Anzahl von separat gefertigten Bauteilen aufgebaut ist und bei Sicherstellung der erforderlichen Überlaufleistung ein vergleichsweise geringes Aufbaumaß besitzt.Based on this, the present invention has the object to provide a supply and overflow fitting for a bathtub, which the four functions mentioned in the EP 1 793 052 A2 known supply and overflow fitting offers concealed the polluting inlet region of the overflow, is constructed from the smallest possible number of separately manufactured components and has a comparatively low construction dimension in ensuring the necessary overflow performance.

Zur Lösung dieser Aufgabe wird eine Zu- und Überlaufarmatur mit den Merkmalen des Anspruchs 1 vorgeschlagen.To solve this problem, a supply and overflow fitting with the features of claim 1 is proposed.

Bevorzugte und vorteilhafte Ausgestaltungen der erfindungsgemäßen Zu- und Überlaufarmatur sind in den Unteransprüchen angegeben.Preferred and advantageous embodiments of the inlet and overflow fitting according to the invention are specified in the subclaims.

Die erfindungsgemäße Zu- und Überlaufarmatur umfasst einen an einer Durchgangsöffnung der Wannenwandung festlegbaren Überlaufkörper, der einen Überlaufkanal und einen Wasseranschluss aufweist, einen kappenförmigen Drehgriff zur Betätigung eines Ablaufventils der Badewanne, einen einen Zulaufkanal aufweisenden Klemmkörper, wobei der Zulaufkanal in die Badewanne mündet, und mindestens ein Befestigungsmittel zur Befestigung von Überlaufkörper und Klemmkörper, wobei der Drehgriff mit einer sich in den Überlaufkörper erstreckenden Mitnehmerwelle versehen ist. Des Weiteren ist die erfindungsgemäße Zu- und Überlaufarmatur dadurch gekennzeichnet, dass die Mitnehmerwelle oder der Drehgriff axial bewegbar gelagert ist, so dass der Drehgriff aus einer ersten Position in eine zweite Position, die gegenüber der ersten Position weiter von dem Überlaufkörper entfernt liegt, und umgekehrt bewegbar ist, wobei der Drehgriff in der ersten Position mit dem Klemmkörper einen ein erhöhtes Überlaufniveau definierenden Wassereinlauf bildet, und wobei der Drehgriff in der zweiten Position mit dem Klemmkörper einen auch nach unten offenen, ein tieferes Überlaufniveau definierenden Wassereinlauf begrenzt.The inlet and overflow fitting according to the invention comprises a fixable on a passage opening of the tub wall overflow body having an overflow channel and a water connection, a cap-shaped rotary handle for actuating a drain valve of the bathtub, a supply channel having a clamping body, wherein the inlet channel opens into the bathtub, and at least a fastening means for fixing overflow body and clamping body, wherein the rotary handle is provided with a driving shaft extending in the overflow body. Furthermore, the inlet and overflow fitting according to the invention is characterized in that the driver shaft or the rotary handle is mounted axially movable, so that the rotary handle from a first position to a second position, which is located opposite to the first position of the overflow body, and vice versa is movable, wherein the rotary handle in the first position with the clamping body forms a raised overflow level defining water inlet, and wherein the rotary handle in the second position with the clamping body defines a downwardly open, a deeper overflow level defining water inlet.

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

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

Im Unterschied zu der aus der EP 1 793 052 A2 bekannten Zu- und Überlaufarmatur erfordert die erfindungsgemäße Zu- und Überlaufarmatur aber außer dem Drehgriff kein zusätzliches, separat gefertigtes Bedienelement (Stellelement) für die Wasserstandsanhebung. Die erfindungsgemäße Zu- und Überlaufarmatur zeichnet sich somit dadurch aus, dass mehrere Bedienfunktionen in einem einzigen Bedienelement, nämlich dem Drehgriff integriert sind. Der verschmutzende Einlaufbereich des Überlaufs befindet sich dabei verdeckt hinter dem kappenförmigen Drehgriff. Der verschmutzende Einlaufbereich des Überlaufs ist vorzugsweise radial beabstandet zum Umfang des Drehgriffs angeordnet. Zudem lässt sich die erfindungsgemäße Zu- und Überlaufarmatur aufgrund des Wegfalls eines zusätzlichen Bedienelements für die Wasserstandsanhebung mit vergleichsweise geringem Aufbaumaß bei gleichzeitiger Sicherstellung der erforderlichen Überlaufleistung verwirklichen.Unlike the one from the EP 1 793 052 A2 known inlet and overflow fitting requires the inlet and overflow fitting according to the invention but except the rotary handle no additional, separately manufactured control element (actuator) for the water level increase. The inlet and overflow fitting according to the invention is thus characterized by the fact that several operating functions are integrated in a single operating element, namely the rotary handle. The polluting inlet area of the overflow is concealed behind the cap-shaped rotary handle. Of the polluting inlet area of the overflow is preferably arranged radially spaced from the circumference of the rotary handle. In addition, the inlet and overflow fitting according to the invention can be realized due to the omission of an additional control element for raising the water level with a comparatively small structural dimension while ensuring the necessary overflow performance.

Die Mitnehmerwelle 13 ist hierzu, wie bereits erwähnt, als Keilwelle ausgebildet und greift axial verschiebbar in die innen verzahnte Ausnehmung 12.1 des im Überlaufkörper 2 drehbar gelagerten Ritzels 12 ein. In der ersten Position bildet der kappenförmige Drehgriff 10 mit dem Klemmkörper 15 einen taschen- oder manschettenförmigen Wassereinlauf, der ein erhöhtes Überlaufniveau definiert (siehe Fig. 5). In der zweiten Position begrenzt der Drehgriff 10 mit dem Klemmkörper 15 einen auch nach unten offenen, ein tieferes Überlaufniveau definierenden Wassereinlauf (siehe Fig. 4).To set or change the overflow level, the cam shaft 13 is mounted axially movable, so that the cap-shaped rotary handle 10 connected to the driving shaft from a first position to a second position, which is located opposite the first position away from the overflow body 2, and vice versa can.

An dem Flansch 15.1 des Klemmkörpers ist ferner ein kreisbogensegmentförmiger Steg 15.11 angeformt, der im montierten Zustand des Klemmkörpers 15 in die Badewanne vorsteht bzw. der Innenseite des Drehgriffs 10 zugewandt ist. Der Steg 15.11 ist an der unteren Umfangshälfte des Flansches 15.1 ausgebildet. Die Außenseite des Steges 15.11 ist im montierten Zustand der Armatur 1 nach unten gewandt. Der Steg 15.11 wird von dem kappenförmigen Drehgriff 10 umgriffen und weist mehrere radiale Durchgangsöffnungen 15.12 auf. Die als Überlauföffnung dienenden Durchgangsöffnungen 15.12 sind länglich oder schlitzförmig ausgebildet. Der Steg 15.11 versteift den Klemmkörper 15 und dient als Gleitführung für den Drehgriff 10, wobei der Steg im Wesentlichen parallel zu dem nach hinten vorstehenden Randsteg 10.1 des Drehgriffs verläuft. In der in Fig. 4 dargestellten Position des Drehgriffs 10 liegt ein umlaufender Wassereinlauf vor, so dass Wasser bei Übersteigen des niedrigen Überlaufniveau WN über die im Steg 15.11 ausgebildeten Durchgangsöffnungen 15.12 in den Überlaufkörper 2 fließen kann.On the flange 15.1 of the clamp body, a circular arc segment-shaped web 15.11 is further formed, which projects in the mounted state of the clamping body 15 in the bath or the inside of the rotary handle 10 faces. The web 15.11 is formed on the lower peripheral half of the flange 15.1. The outside of the web 15.11 is in the assembled state of the valve 1 down looking. The web 15.11 is encompassed by the cap-shaped rotary handle 10 and has a plurality of radial passage openings 15.12. The passage openings 15.12 serving as the overflow opening are elongate or slot-shaped. The web 15.11 stiffens the clamping body 15 and serves as a sliding guide for the rotary handle 10, wherein the web is substantially parallel to the rearwardly projecting edge web 10.1 of the rotary handle. In the in Fig. 4 illustrated position of the rotary handle 10 is a circumferential water inlet, so that water can flow into the overflow body 2 when exceeding the low overflow level W N on the formed in the web 15.11 through holes 15.12.

Zur Arretierung des Drehgriffs 10 in seiner ersten Position sowie in seiner zweiten Position weist das hohlschraubenartige Befestigungsmittel 16 eine Federhülse 16.3 auf, die mit einem innenseitig radial vorstehenden Rastvorsprung 16.4 versehen ist, während die Mitnehmerwelle 13 dem Rastvorsprung 16.4 zugeordnete, axial beanstandete Ausnehmungen 13.1, 13.2 aufweist. Der Drehgriff 10 kann durch leichtes Drücken aus der in Fig. 4 gezeigten Position in die in Fig. 5 gezeigte Position bewegt werden, und umgekehrt durch leichtes Ziehen wieder zurück bewegt werden.To lock the rotary handle 10 in its first position and in its second position, the hollow screw-like fastening means 16 a spring sleeve 16.3, which is provided with an inside radially projecting locking projection 16.4, while the cam shaft 13 the locking projection 16.4 associated, axially spaced recesses 13.1, 13.2 having. The rotary handle 10 can be easily pressed out of the in Fig. 4 shown position in the Fig. 5 be moved shown position, and vice versa moved back by gently pulling back.

Optional sind an der Rückseite des Drehgriffs 10 und/oder an der dem Drehgriff zugewandeten Vorderseite des Klemmkörpers 15 schiefe Ebenen oder rampenartigen Gleitflächen ausgebildet, die bewirken, dass der Drehgriff 10 beim Drehen um die Mitnehmerwelle 13 zwangsläufig aus der ersten, ein erhöhtes Überlaufniveau bewirkenden Position in die zweite Position gebracht wird.Optionally, 15 inclined planes or ramp-like sliding surfaces are formed on the back of the rotary handle 10 and / or on the rotary handle facing the front side, which cause the rotary handle 10 when rotating about the cam shaft 13 inevitably from the first, an elevated overflow level causing position is brought into the second position.

Die Federhülse 16.3 ist koaxial innerhalb des flanschförmigen Kopfabschnitts 16.2 der Hohlschraube 16 ausgebildet. Sie weist eine als Mehrkant, vorzugsweise Sechskant ausgebildete Mantelfläche 16.5 auf und ist radial geschlitzt. Zwischen dem flanschförmigen Kopfabschnitt 16.2 und der Federhülse 16.3 ist eine ringförmige Aussparung 16.6 vorhanden, so dass die als Mehrkant ausgebildete Mantelfläche 16.5 der Federhülse mit einem entsprechenden Werkzeug, beispielsweise einem Steckschlüssel, formschlüssig erfasst werden kann.The spring sleeve 16.3 is formed coaxially within the flange-shaped head portion 16.2 of the hollow screw 16. It has a designed as a polygonal, preferably hexagonal lateral surface 16.5 and is radially slotted. Between the flange-shaped head section 16.2 and the spring sleeve 16.3 there is an annular recess 16.6, so that the lateral surface 16.5 of the spring sleeve formed as a polygon can be positively locked with a corresponding tool, for example a socket wrench.

Der flanschförmige Kopfabschnitt 16.2 der Hohlschraube 16, der Rastvorsprung 16.4 der Federhülse 16.3 sowie die dem Rastvorsprung zugeordneten Ausnehmungen 13.1, 13.2 der Mitnehmerwelle 13 sind so bemessen und angeordnet, dass der Drehgriff 10 in seiner den erhöhten Wasserstand WH hervorrufenden Position an dem flanschförmigen Kopfabschnitt 16.2 anliegt.The flange-shaped head portion 16.2 of the hollow bolt 16, the locking projection 16.4 of the spring sleeve 16.3 and the associated snap-in protrusion recesses 13.1, 13.2 of the carrier shaft 13 are so sized and arranged that the rotary handle 10 in its the increased water level W H inducing position on the flange-shaped head portion 16.2 is applied.

Des Weiteren ist in der Zeichnung zu erkennen, dass der flanschförmige Kopfabschnitt 16.2 des Befestigungsmittels 16 eine sich in Richtung des Überlaufkörpers 2 verjüngende Mantelfläche 16.7 mit konkaver Mantellinie aufweist. In Kombination mit dem trichterartigen Flansch 15.1 des Klemmkörpers 15 ergibt sich somit ein im Wesentlichen ringförmiger Einlaufkanal, dessen lichte Strömungsweite in Richtung des hülsenförmigen Innenabschnitts 15.2 des Klemmkörpers 15 allmählich abnimmt. Der verschmutzende Einlaufbereich des Überlaufs ist dabei radial beabstandet zum Umfang bzw. Randsteg 10.1 des Drehgriffs 10 angeordnet. Dies gilt insbesondere für den oberen Einlaufbereich des Überlaufs. Der verschmutzende Einlaufbereich des Überlaufs der Zu- und Überlaufarmatur 1 ist somit wirksam verdeckt und für den Nutzer der Badewanne nicht sichtbar.Furthermore, it can be seen in the drawing that the flange-shaped head section 16.2 of the fastening means 16 has a jacket surface 16.7 tapering in the direction of the overflow body 2 with a concave generatrix. In combination with the funnel-like flange 15.1 of the clamping body 15 thus results in a substantially annular inlet channel whose clear flow in the direction of the sleeve-shaped inner portion 15.2 of the clamping body 15 gradually decreases. The polluting inlet region of the overflow is arranged radially spaced from the circumference or edge web 10.1 of the rotary handle 10. This applies in particular to the upper inlet area of the overflow. The polluting inlet area of the overflow of the inflow and overflow fitting 1 is thus effectively concealed and not visible to the user of the bath.

Der an dem kappenförmigen Drehgriff 10 rückseitig vorstehende Randsteg 10.1 ist im Wesentlichen U-förmig ausgebildet. Die oberen Enden 10.11 des U-förmigen Stegabschnitts sind durch einen Quersteg 10.12, der ebenfalls von der Rückseite des Drehgriffs 10 vorsteht, verbunden. Die im Wesentlichen plan oder flach ausgebildete Vorderseite des Drehgriffs 10 geht oben mit einer abgerundeten oder gebogenen Kante 10.13 in den Quersteg 10.12 über. Der üblicherweise während des Gebrauchs der Armatur 1 verschmutzende Einlaufbereich des Überlaufs liegt hinter dem kappenförmigen Drehgriff 10, so dass dieser Schmutzbereich verdeckt ist.The on the cap-shaped rotary handle 10 back protruding edge web 10.1 is formed substantially U-shaped. The upper ends 10.11 of the U-shaped web portion are connected by a crossbar 10.12, which also protrudes from the back of the rotary handle 10. The substantially flat or flat trained front of the rotary handle 10 goes above with a rounded or curved edge 10.13 in the cross bar 10.12 over. The usually during use of the fitting 1 polluting inlet area of the overflow is behind the cap-shaped rotary handle 10, so that this dirt area is covered.

Des Weiteren kann die Zu- und Überlaufarmatur 1 eine optionale Abdeckung (Sichtblende) 19 umfassen. In dem dargestellten Ausführungsbeispiel ist der Klemmkörper 15 in einer ringförmigen oder bogenförmigen Abdeckung (Sichtblende) 19 aufgenommen. Die Abdeckung 19 weist eine nach unten mündende Ausnehmung 19.1 auf, die der Aufnahme des Strahlreglers 17 dient.Furthermore, the inlet and overflow fitting 1 may comprise an optional cover 19. In the illustrated embodiment, the clamping body 15 in an annular or arcuate cover (screen) 19 recorded. The cover 19 has a downwardly opening recess 19.1, which serves to receive the jet regulator 17.

Die Erfindung ist in ihrer Ausführung nicht auf das in der Zeichnung dargestellte Ausführungsbeispiel beschränkt. Vielmehr sind zahlreiche Varianten denkbar, die auch bei grundsätzlich abweichender Gestaltung von dem in den Ansprüchen angegebenen Erfindungsgedanken Gebrauch machen.The invention is not limited in its embodiment to the embodiment shown in the drawing. Rather, numerous variants are conceivable, which make use of the idea given in the claims according to the invention even with fundamentally different design.
