Abstract

A sanitary drain valve actuating Bowden cable consists of a plastic string (10) and of a plastic hose (20). Both elements are provided with union couplings for transmitting the regulating movement from an actuating element (4) to a valve lever (2). The string (10) and its union couplings (12, 13) form a single piece. The string (10) is produced with at least one union coupling (12, 13) made of thermoplastic material in a single injection operation inside a combined injection mold. A union coupling (22, 23) made of the same thermoplastic material as the Bowden cable hose (20) or of a compatible plastic material is injected or glued on the outside of the hose (20). Extraordinarily reliable and resistant unions are thus obtained, as the hermetic enclosure ensures an additional sealing against humidity, steam or corrosive influences. Mounting at the site of use is particularly easy and reliable.

Description

Bowdenzug für Ventilbetätigung an einem Sanitär-Ablaufventil und Verfahren zu seiner Herstellung Bowden cable for valve actuation on a sanitary drain valve and method for its production
Die Erfindung betrifft einen Bowdenzug für die Ventilbetätigung an einem Sanitär-Ablaufventil nach Patentanspruch 1, sowie ein Verfahren zu dessen Herstellung.The invention relates to a Bowden cable for valve actuation on a sanitary drain valve according to claim 1, and a method for its production.
Mit Bowdenzug ausgerüstete Ventilbetätigungen werden an Sanitär- Ablaufventilen eingesetzt, wie sie z.B. an Spültrögen für Küchen oder Badezimmer Verwendung finden. An solchen Ablaufventilen befindet sich ein Ventilstopfen, der durch ein Hand-Betäti¬ gungselement von einer davon getrennten Armatur aus oder durch einen gesteuerten Hilfsantrieb betätigt wird. Der zur Ueber- tragung der Stell-Bewegung verwendete Bowdenzug ermöglicht auf vorteilhafte Weise die universelle Montage der Ventile. Unter¬ stützt durch geeignete Befestigungsmittel sind bekannte Ventile z.B. zum Einbau in Blechtrögen mit Wandstärken von 1 bis 3 Millimeter wie auch in Steinkombinationen mit Wandstärken von z.B. 20 Millimeter vorbereitet. Der Bowdenzug überbrückt solche Differenzen ohne weitere Anpassarbeiten.Valve actuators equipped with a Bowden cable are used on sanitary drain valves such as those e.g. can be used on kitchen or bathroom sinks. A valve plug is located on such drain valves, which is actuated by a manual actuation element from a valve separate therefrom or by a controlled auxiliary drive. The Bowden cable used to transmit the actuating movement advantageously enables universal mounting of the valves. Known valves are supported by suitable fastening means, e.g. for installation in sheet metal troughs with wall thicknesses of 1 to 3 millimeters as well as in stone combinations with wall thicknesses of e.g. 20 millimeters prepared. The Bowden cable bridges such differences without further adjustment work.
Herkömmliche Bowdenzuge sind für den geschilderten Einsatz je¬ doch nur bedingt brauchbar, da ihre Handhabung nicht genügend an die besonderen Gegebenheiten während der Montage der Ab¬ laufventile und der Armaturen angepasst ist. Ferner haben sich die konventionellen Bowdenzuge im späteren Gebrauch oftmals als zu wenig robust erwiesen, insbesondere unter dem Einfluss von Kalkablagerungen. Aufgabe der vorliegenden Erfindung ist es, den Bowdenzug für die Ventilbetätigung an einem Sanitär-Ablaufventil so zu ver¬ bessern bzw. anzupassen, dass eine einfache, universelle Mon¬ tage für die verschiedenen Einbaumöglichkeiten von Ablauf¬ ventilen gewährleistet ist. Ferner soll der Bowdenzug besonders robust und im späteren Gebrauch wenig störanfällig sein. Die Herstellung soll mit bewährten und vorhandenen Produktions¬ mitteln auf einfache und kostengünstige Weise erfolgen. Erfin- dungsgemäss werden diese Aufgaben durch die in den Patent¬ ansprüchen 1 und 7 definierten Massnah en gelöst.Conventional Bowden cables are, however, only of limited use for the use described, since their handling is not sufficiently adapted to the special circumstances during the assembly of the drain valves and the fittings. Furthermore, the conventional Bowden cables often proved to be insufficiently robust in later use, especially under the influence of limescale. The object of the present invention is to improve or adapt the Bowden cable for valve actuation on a sanitary drain valve in such a way that simple, universal assembly is ensured for the various installation options for drain valves. Furthermore, the Bowden cable should be particularly robust and less susceptible to failure in later use. The production is to be carried out in a simple and inexpensive manner using proven and existing production means. According to the invention, these tasks are solved by the measures defined in claims 1 and 7.
Insbesondere für die erwähnten Einsatzfälle hat sich der erfin- dungsgemässe Bowdenzug als besonders montagefreundlich, robust und wenig störanfällig erwiesen. Das Herstellungsverfahren er¬ möglicht den Einsatz einfacher Produktionsmittel. Die Herstel¬ lung ist kostengünstig und führt zu zuverlässigen Produkten, auch für besonders erschwerte Einsatzgebiete.The Bowden cable according to the invention has proven to be particularly easy to install, robust and less prone to failure, in particular for the applications mentioned. The manufacturing process enables the use of simple means of production. The manufacture is inexpensive and leads to reliable products, even for particularly difficult areas of use.
Durch das direkte Anspritzen von Anschlussteilen direkt auf den Schlauch des Bowdenzugs wird eine gleichmässige und vor allem zuverlässigere Umschlieεsung mit Kunststoff erreicht, wodurch sich eine zuverlässige und beständige Verbindung ergibt. Die hermetische Umschliessung bildet auf vorteilhafte Weise zusätz¬ lich eine Abdichtung gegen Feuchtigkeit, Dampf oder korrosive Einflüsse. Der Bowdenzug ist von konstant guter Qualität, wobei keine Nacharbeit erforderlich ist und trotzdem unerwartet gute und langzeit-beständige Gleiteigenschaften der Saite an der Innenwand des Schlauchs erzielt werden.The direct injection molding of connecting parts directly onto the hose of the Bowden cable achieves a uniform and, above all, more reliable encapsulation with plastic, which results in a reliable and permanent connection. The hermetic enclosure advantageously also forms a seal against moisture, steam or corrosive influences. The Bowden cable is of consistently good quality, with no reworking required and nevertheless unexpectedly good and long-term sliding properties of the string are achieved on the inner wall of the hose.
Einzelheiten und weitere Vorteile der Erfindung werden im folgenden anhand von Ausführungsbeispielen mit Hilfe von Zeichnungen näher erläutert. Es zeigen:Details and further advantages of the invention are explained in more detail below on the basis of exemplary embodiments with the aid of drawings. Show it:
Fig.l einen Bowdenzug mit einer Veήtilbetätigung an einem Sanitär-Ablaufventil in Schnittdarstellung, Fig.2 Schnittdarstellungen der Bowdenzug-Saite, mit Ver¬ bindungselementen, gemäss Fig.l, undFIG. 1 shows a Bowden cable with a valve actuation on a sanitary drain valve in a sectional view, 2 shows sectional views of the Bowden cable string, with connecting elements, according to FIG. 1, and
Fig.3 die Schnittdarstellung des Bowdenzug-Schlauchs mit angespritzten Verbindungselementen gemäss Fig.l.3 shows the sectional view of the Bowden cable hose with molded connecting elements according to Fig.l.
In Fig.l ist das Beispiel einer Gesamtanordnung gezeigt, mit einem Ablaufventil 1, seinem Ventilhebel 2 sowie einem Bowden¬ zug, der aus einer Saite 10 und einem Schlauch 20 besteht. Der Bowdenzug überträgt die Stellbewegung auf den Ventilhebel 2. Im Beispiel kommt die Stellbewegung von einer Armatur 3, in welcher ein Betätigungsknopf 4 zum Oeffnen bzw. Schliessen des Ventils 1 nach unten gestossen bzw. nach oben gezogen wird. Die in der Figur dargestellten Halbschnitte zeigen links die Posi¬ tion für das geöffnete und rechts für das geschlossenen Ventil. Saite 10 und Schlauch 20 des Bowdenzugs bestehen aus thermo¬ plastischen Kunststoffen, die Saite im Beispiel aus POM- (Polyoxymethylen) und der Schlauch aus einem PE-Kunststoff (Polyethylen) .In Fig.l the example of an overall arrangement is shown, with a drain valve 1, its valve lever 2 and a Bowden cable, which consists of a string 10 and a hose 20. The Bowden cable transmits the actuating movement to the valve lever 2. In the example, the actuating movement comes from a fitting 3, in which an actuating button 4 for opening or closing the valve 1 is pushed down or pulled up. The half-cuts shown in the figure show the position on the left for the open valve and on the right for the closed valve. String 10 and hose 20 of the Bowden cable consist of thermoplastic plastics, the string in the example from POM (polyoxymethylene) and the hose from a PE plastic (polyethylene).
An der Kunststoff-Saite 10 ist gemäss Fig. 2 ein Anschluss¬ element zum Ventilhebel 2 ausgebildet, im Beispiel eine Oese 12. Am entgegengesetzten Ende der Saite 10 befindet sich eine Schnapp-Kupplung 13, welche die Verbindung zum Betätigungsknopf 4 darstellt. Beide Anschlusselemente 12, 13 sind vorzugsweise zusammen mit der Saite 10 aus einem Stück vom gleichen Material und an der Saite 10 direkt angeformt, entsprechend der Aus¬ bildung der für den Herstellungsprozess verwendeten Spritzform. Es kann aber auch nur eines der Anschlusselemente direkt an der Saite 10 angeformt sein, wenn die konstruktiven Umstände dies erfordern. Die Grundformen der Anschlusselemente sind-ent¬ sprechend einfach gehalten, so dass der Spritzvorgang mit ein¬ fachen Mitteln und ohne Schwierigkeiten erfolgen kann. Vor¬ zugsweise erfolgt der Spritzvorgang für die Saite 10 und ihre Anschlusselemente 12, 13 in einem einzigen Spritzvorgang mit einer .entsprechend ausgebildeten Form.According to FIG. 2, a connecting element to the valve lever 2 is formed on the plastic string 10, in the example an eyelet 12. At the opposite end of the string 10 there is a snap coupling 13, which represents the connection to the actuation button 4. Both connection elements 12, 13 are preferably molded together with the string 10 from a single piece of the same material and directly on the string 10, in accordance with the design of the injection mold used for the manufacturing process. However, only one of the connection elements can be molded directly onto the string 10 if the structural circumstances so require. The basic shapes of the connection elements are accordingly kept simple, so that the spraying process can be carried out with simple means and without difficulty. The spraying process for the string 10 and its is preferably carried out Connection elements 12, 13 in a single spraying operation with a correspondingly designed shape.
Auch der Schlauch 20 des Bowdenzugs ist mit Anschlusselementen 22, 23 versehen. Das erste Schlauch-Anschlusselement 22 wird am Ventilkörper 1 gehalten. Dies erfolgt z.B. in Schnapp-Halte- rungen 25, 26, die am Ventilkδrper 1 angebracht sind und die im Beispiel jeweils eine Bohrung und einen federnden Einsteck¬ schlitz aufweisen, in welche das erste Anschlusselement 22 von der Seite her (in der Zeichenebene von oben) eingerastet wird. Zur exakten Positionierung des Anschluεselementes 22 in axialer Richtung dient im Beispiel ein Distanzstück 24 am Anschluss- ele ent 22, welches zwischen den beiden Schnapp-Halterungen 25, 26 im Sinne eines abgesetzten Bundes zu liegen kommt.The hose 20 of the Bowden cable is also provided with connecting elements 22, 23. The first hose connection element 22 is held on the valve body 1. This is done e.g. in snap brackets 25, 26 which are attached to the valve body 1 and which in the example each have a bore and a resilient insertion slot into which the first connection element 22 is latched from the side (in the drawing plane from above) . For exact positioning of the connection element 22 in the axial direction, a spacer 24 on the connection element 22 is used in the example, which comes to rest between the two snap brackets 25, 26 in the sense of a stepped collar.
Aehnlich rastet im bevorzugten Beispiel die Saite 10 mit ihrer Oese 12 auf einem Rastnocken 27 ein, der am Ventilhebel 2 ange¬ bracht ist. Auf diese Weise wird eine besonders einfache und sichere Montage des Bowdenzuges durch seitliches Aufstecken des Schlauches 20 mit dem Anschlusselement 22 in die Schnapp-Halte¬ rungen 25, 26 und Aufstecken der Oese 12 auf den Rastnocken 27 des Ventilhebels 2 erreicht. Für beide Elemente des Bowdenzugs erfolgt das Anschliessen auf vorteilhafte Weise durch einfaches Aufstecken in der gleichen Richtung und praktisch in einem einzigen Arbeitsgang._Similarly, in the preferred example, the string 10 engages with its eyelet 12 on a locking cam 27 which is attached to the valve lever 2. In this way, a particularly simple and secure assembly of the Bowden cable is achieved by laterally plugging the hose 20 with the connecting element 22 into the snap holders 25, 26 and plugging the eyelet 12 onto the locking cams 27 of the valve lever 2. For both elements of the Bowden cable, the connection is advantageously made by simply plugging in the same direction and practically in a single operation.
Das zweite, obere Schlauch-Anschlusselement 23 gemäss Fig. 1 ist als Halterung der gesamten Betätigungsvorrichtung in der Spüle 5 oder in einer beliebigen Abdeckung ausgebildet. Wie aus Fig. 3 hervorgeht, besitzt es einen Aufsatz 28 zum Anschlag auf der Oberseite der Spüle 5, ferner ein Gewinde 29, zur Aufnahme einer Montageschraube 30.The second, upper hose connection element 23 according to FIG. 1 is designed as a holder for the entire actuating device in the sink 5 or in any cover. As can be seen from FIG. 3, it has an attachment 28 for abutment on the top of the sink 5, and also a thread 29 for receiving an assembly screw 30.
Schliesslich weist das Schlauch-Anschlusselement 23 im oberen Teil eine Rast-Nase 31 sowie im oberen zentralen Teil eine Rückhaltebohrung 32 auf. Die Rast-Nase 31 hält eine Schutz¬ bzw. Abdeck-Rosette 33, welche mit einem Vorsprung 34 versehen ist. Der Vorsprung rastet unter die Rast-Nase 31 des Schlauch- Anschlusselementes 23. Die untere Kante der Rückhaltebohrung 32 stellt eine Hubbegrenzung für eine Schlepp-Hülse 36 dar.Finally, the hose connection element 23 has a latching lug 31 in the upper part and one in the upper central part Retaining hole 32 on. The latching nose 31 holds a protective or cover rosette 33, which is provided with a projection 34. The projection engages under the locking lug 31 of the hose connection element 23. The lower edge of the retaining bore 32 represents a stroke limitation for a drag sleeve 36.
Die Rückhaltebohrung 32 im Schlauch-Anschlusselement 23 dient der Schlepp-Hülse 36 als zentrale Führung und begrenzt deren Bewegung nach unten. Oben weist die Schlepp-Hülse 36 einen Aufsatz 37 auf, hinter den die Schnapp-Kupplung 13 der Saite 10 rastet. Ausserdem rastet hinter einer Aussenkante 38 der Schlepp-Hülse 36 der Betätigungsknopf 4 mit einem entsprechen¬ den inneren Vorsprung 39. Die Schlepp-Hülse 36 erfüllt im be¬ schriebenen Beispiel eine dreifach Funktion: Sie stellt eine Führung für den Betätigungsknopf 4 dar, ferner dient sie als Halterung für die Saite 10, und schliesslich wirkt sie als Hubbegrenzung für die Bewegung des Betätigungsknopfes 4 nach unten.The retaining bore 32 in the hose connection element 23 serves as a central guide for the drag sleeve 36 and limits its downward movement. At the top, the drag sleeve 36 has an attachment 37, behind which the snap coupling 13 of the string 10 snaps. In addition, behind an outer edge 38 of the drag sleeve 36, the actuation button 4 snaps with a corresponding inner projection 39. In the example described, the drag sleeve 36 fulfills a triple function: it represents a guide for the actuation button 4 and also serves it as a holder for the string 10, and finally it acts as a stroke limitation for the movement of the actuating button 4 downwards.
Die zuletzt beschriebene Betätigungsvorrichtung mit dem Bowden¬ zug lässt sich durch einfaches Zusammenstecken vormontieren. Zur Endmontage am Becken wird die vormontierte Einheit von oben durch eine entsprechende Oeffnung in der Spüle 5 oder im Tisch geschoben und mit der Montageschraube 30 von unten befestigt. Nach dem ober bereits -beschriebenen Anschluss der Saite 10 an den Ventilhebel 2 und des Schlauchs 20 an den Ventilkörper durch einfaches Einrasten ist die Montage bereits abgeschlos¬ sen. Es sind keine weiteren mechanischen Nacharbeiten oder An¬ passungen erforderlich, so dass die Montage in kürzester Zeit zu bewerkstelligen ist.The last described actuating device with the Bowden cable can be preassembled by simply plugging it together. For final assembly on the basin, the pre-assembled unit is pushed from above through a corresponding opening in the sink 5 or in the table and fastened with the mounting screw 30 from below. After the above-described connection of the string 10 to the valve lever 2 and the hose 20 to the valve body by simply latching in, the assembly is already completed. No further mechanical reworking or adjustments are necessary, so that the assembly can be carried out in the shortest possible time.
Es sei noch bemerkt, dass die beschriebenen Anschlusselemente und die auf eine vereinfachte Montage gerichteten Verbindungs¬ elemente an der Betätigungsvorrichtung jeweils eines von vielen möglichen Ausführungsbeispielen darstellen. Auf die Beschrei- bung weiterer im Rahmen dieser Erfindung liegender Ausführungs- 'formen wird verzichtet, da sie dem Fachmann naheliegen dürften.It should also be noted that the connection elements described and the connection elements on the actuating device which are aimed at simplified assembly each represent one of many possible exemplary embodiments. On the descriptive bung further lying within the scope of this invention execution 'shape is omitted since they are likely to be close to the skilled person.
Es versteht sich ferner, dass anstelle des Betätigungsknopfes 4 eine beliebige andere Betätigungsvorrrichtung, z.B. ein Motor¬ antrieb, angeschlossen werden kann, ohne von der einfachen und zweck ässigen Ausbildung des Bowdenzugs und seiner Anschluss¬ elemente abweichen zu müssen.It is further understood that, instead of the actuation button 4, any other actuation device, e.g. a motor drive can be connected without having to deviate from the simple and practical design of the Bowden cable and its connecting elements.
Zur Herstellung der Saite 10 genügt ein einziger Spritzvorgang aus einer kombinierten Spritzform für die Saite und mindestens eines der Anschlusselemente 12, 13. Besonders vorteilhaft ist jedoch die gleichzeitige Ausbildung beider Anschlusselemente. Am Schlauch 20 lassen sich die Anschluεselemente 22, 23 aus gleichem oder verträglichem Thermoplast von aussen an das Schlauchmaterial anspritzen. Zum Anspritzen wird das Schlauch¬ ende in eine entsprechende Form für das Anschlussteil eingelegt und dann umspritzt. Klebeverbindungen sind als Alternative ebenfalls möglich. In diesem Fall werden vorbereitete An¬ schlusselemente auf das Schlauchende gesteckt und mit diesem verklebt. To produce the string 10, a single injection process from a combined injection mold for the string and at least one of the connection elements 12, 13 is sufficient. However, the simultaneous formation of both connection elements is particularly advantageous. The connecting elements 22, 23 of the same or compatible thermoplastic on the hose 20 can be injection molded onto the outside of the hose material. For injection, the end of the hose is inserted into a corresponding shape for the connecting part and then overmolded. Adhesive connections are also possible as an alternative. In this case, prepared connection elements are plugged onto the hose end and glued to it.
