Description

Die Erfindung betrifft ein Einlaufventil nach dem Oberbe­griff des unabhängigen Patentanspruchs 1.The invention relates to an inlet valve according to the preamble of independent claim 1.

Durch die CH-A 396 790 ist ein Einlaufventil bekannt gewor­den, das eine Muffe mit einem Aussengewinde aufweist, die eine Seitenwand des Spülkastengehäuses durchsetzt und an diesem mittels einer von aussen aufgeschraubten Schrauben­mutter fixiert ist. Die Muffe ist an ihrem freien Ende mit einer auf das Aussengewinde aufgeschraubten Ueberwurfmutter an einer Wasserleitung angeschlossen. Ueber diese Wasser­leitung wird der Spülkasten versorgt.From CH-A 396 790 an inlet valve has become known which has a sleeve with an external thread which passes through a side wall of the cistern housing and is fixed thereon by means of a screw nut screwed on from the outside. At its free end, the sleeve is connected to a water pipe with a union nut screwed onto the external thread. The cistern is supplied via this water pipe.

Die Befestigung und eine Demontage dieses Einlaufventils ist zeitaufwendig und oft schwierig und eine automatische Montage ist nicht möglich oder zumindest sehr aufwendig.The attachment and disassembly of this inlet valve is time consuming and often difficult and automatic assembly is not possible or at least very complex.

Um den Anschluss in ästhetischer Hinsicht zu gestalten, muss eine zusätzliche Manschette angebracht werden.To make the connection aesthetically, an additional sleeve must be attached.

Der Erfindung lag die Aufgabe zugrunde, ein Einlaufventil der genannten Art zu schaffen, das in einfacher Weise und insbesondere auch mittels automatisierter Montage am Ge­häuse des Spülkastens befestigt werden kann und das eine kostengünstige und weitgehend ästhetische Gestaltung des Anschlusses ermöglicht.The invention had for its object to provide an inlet valve of the type mentioned, which can be fastened in a simple manner and in particular also by means of automated assembly to the housing of the cistern and which enables an inexpensive and largely aesthetic design of the connection.

Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 ge­löst.The object is achieved by the invention according to claim 1.

Das erfindungsgemässe Einlaufventil lässt sich einfacher und schneller am Spülkasten befestigen als das eingangs genannte Ventil. Eine automatische oder automatisierte Montage lässt sich mit vergleichsweise geringem Aufwand realisieren, da das Befestigungsteil mit einer kurzen linearen Bewegung aufgesetzt werden kann und weitere Mittel und Aufwendungen für die ästhetische Gestaltung des An­schlusses nicht erforderlich sind. Die äussere Formgebung des Befestigungsteils ist weitgehend frei und gibt dem Designer einen weiten Spielraum für die Gestaltung.The inlet valve according to the invention can be attached to the cistern more easily and quickly than the valve mentioned at the beginning. An automatic or automated assembly can be implemented with comparatively little effort, since the fastening part can be attached with a short linear movement and further means and expenses for the aesthetic design of the connection are not necessary. The outer shape of the fastening part is largely free and gives the designer a wide scope for design.

Durch die Weiterbildungen nach den Ansprüchen 2 bis 5 wird das Einlaufventil in konstruktiv einfacher Weise so realisiert, dass es wahlweise auf der einen oder anderen Schmalseite des Spülkastengehäuses montiert werden kann.The refinements according to claims 2 to 5, the inlet valve is so in a structurally simple manner realizes that it can optionally be mounted on one or the other narrow side of the cistern housing.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 eine Teildraufsicht auf einen Spülkasten mit abge­nommenem Deckel,
  • Fig. 2 einen Teilschnitt durch den Spülkasten,
  • Fig. 3 eine Ansicht eines Befestigungsteils, und
  • Fig. 4 einen Schnitt durch das Befestigungsteil.
An embodiment of the invention is explained below with reference to the drawings. Show it:
  • 1 is a partial plan view of a cistern with the cover removed,
  • 2 shows a partial section through the cistern,
  • Fig. 3 is a view of a fastener, and
  • Fig. 4 shows a section through the fastening part.

Der in den Fig. 1 und 2 gezeigte Spülkasten weist in übli­cher Weise einen Kastenkörper 8 mit einer innenseitig ange­ordneten Isolation 9 und einen Deckel 10 auf. In den aus Kunststoff hergestellten Kastenkörper 8 ist eine quadra­tische Oeffnung gestanzt, durch die eine Muffe 2 eines Einlaufventils 1 hindurchgesteckt ist. Das Einlaufventil 1 ist beispielsweise ein Schwimmerventil, dessen grundsätz­licher Aufbau allgemein bekannt ist. Der nach aussen ragende Teil 7 der Muffe 2 besitzt ein Aussengewinde 3, auf das zum Anschliessen einer hier nicht gezeigten Wasser­leitung unter Zwischenlage einer Dichtungsscheibe 4 eine Ueberwurfmutter 5 aufgeschraubt wird.The cistern shown in FIGS. 1 and 2 has, in the usual way, a cistern body 8 with an insulation 9 arranged on the inside and a cover 10. A square opening is punched into the box body 8 made of plastic, through which a sleeve 2 of an inlet valve 1 is inserted. The inlet valve 1 is, for example, a float valve, the basic structure of which is generally known. The outwardly projecting part 7 of the sleeve 2 has an external thread 3, to which a sealing washer 4 is interposed for connecting a water line (not shown here) Union nut 5 is screwed on.

Wie die Fig. 2 deutlich zeigt, besitzt die Muffe 2 eine Schulter 18, die auf der Innenseite des Spülkastenkörpers 8 anliegt und an die ein im Querschnitt enger Bereich 17 an­schliesst. An den im Querschnitt kreisrunden Bereich 17 schliesst ein im Querschnitt quadratischer Bereich an. Im Be­reich 6 sind entsprechend vier Vertiefungen 6 vorhanden. In diese Vertiefungen 6 ist lösbar ein aus Kunststoff herge­stellter Befestigungsteil 11 eingesetzt, der das Einlauf­ventil in Wechselwirkung mit der Schulter 18 gegen eine axiale Verschiebung sichert.As FIG. 2 clearly shows, the sleeve 2 has a shoulder 18 which bears against the inside of the cistern body 8 and to which a region 17 with a narrow cross section adjoins. A region 17 that is circular in cross section is adjoined by a region that is square in cross section. Correspondingly, four depressions 6 are present in area 6. A fastening part 11 made of plastic is releasably inserted into these depressions 6, which secures the inlet valve in interaction with the shoulder 18 against axial displacement.

Der in den Fig. 3 und 4 im Detail gezeigte Befestigungsteil besteht aus einem Verriegelungsteil 15 und einem an diesem angeformten, etwa rechtwinklig abstehenden Kragen 13. Der Verriegelungsteil 15 weist einen Einschnitt 12 auf, an dem zwei nach innen vorspringende Nocken 14 angeformt sind. Der auf die Muffe 2 aufgesetzte Befestigungsteil 11 greift mit dem Verriegelungsteil 15 in drei der Vertiefungen 6 ein. Die Nocken 14 stehen an der Muffe 2 an und verhindern, dass sich der Befestigungsteil 11 unbeabsichtigt löst.The fastening part shown in FIGS. 3 and 4 consists of a locking part 15 and a collar 13 formed thereon and projecting approximately at a right angle. The locking part 15 has an incision 12 on which two inwardly projecting cams 14 are formed. The fastening part 11 placed on the sleeve 2 engages with the locking part 15 in three of the recesses 6. The cams 14 are in contact with the sleeve 2 and prevent the fastening part 11 from loosening unintentionally.

Um das Einlaufventil 2 am Spülkastenkörper 8 zu befestigen, wird die Muffe 2 durch die Oeffnung 16 bis zum Anschlag der Schulter 18 hindurchgesteckt und der Befestigungsteil 11 radial auf den äusseren Teil 7 aufgeschoben. Das Einlauf­ventil 1 ist damit am Kastenkörper 8 fixiert und gleich­zeitig der Muffenteil 7 überdeckt. Beim Aufschrauben der Ueberwurfmutter 5 kann diese mit dem vorderen Ende den Kragen 11 bereichsweise untergreifen. Wie die Fig. 4 zeigt, ist der mittige Bereich des Verriegelungselementes 15 etwas nach rechts versetzt, so dass eine ringförmige Fläche 19 vorhanden ist, die beim montierten Ventil an der Aussen­fläche des Kastens 8 anliegt.In order to attach the inlet valve 2 to the cistern body 8, the sleeve 2 is through the opening 16 until the stop Shoulder 18 inserted and the fastening part 11 pushed radially onto the outer part 7. The inlet valve 1 is thus fixed to the box body 8 and at the same time the sleeve part 7 is covered. When the union nut 5 is screwed on, the front end thereof can engage under the collar 11 in certain areas. As shown in FIG. 4, the central region of the locking element 15 is offset somewhat to the right, so that there is an annular surface 19 which, when the valve is mounted, rests on the outer surface of the box 8.

Der Befestigungsteil 11 kann wie in Fig. 2 gezeigt, radial von oben aufgesetzt sein. Bei einem hoch hängenden Spül­kasten wird der Befestigungsteil hingegen von unten auf die Muffe 2 aufgesetzt. Um das Einlaufventil 1 zu demontie­ren, muss lediglich die Ueberwurfmutter 5 gelöst und der Befestigungsteil 11 abgezogen werden.The fastening part 11 can, as shown in FIG. 2, be placed radially from above. In the case of a high-hanging cistern, however, the fastening part is placed on the socket 2 from below. In order to dismantle the inlet valve 1, only the union nut 5 has to be loosened and the fastening part 11 removed.

Aus den obigen Angaben ergibt sich somit ein Einlaufventil, das einfach und schnell montiert und demontiert werden kann und das auch bezüglich der Gestaltung des Spülkastens wesent­liche Vorteile bietet.From the above information, this results in an inlet valve that can be assembled and disassembled quickly and easily and that also offers significant advantages with regard to the design of the cistern.
