Description

Die Erfindung betrifft einen Schlüsselschalter nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a key switch according to the preamble of claim 1.

Bei einem aus der DE-C-2 208 019 bekannten Schlüsselschalter ist in einem Gehäuse ein elektrischer Drehschalter so hinter einem Zylinderschloß angeordnet, daß die Zylinderachse des Zylinderschlosses im wesentlichen koaxial mit der Drehachse des Schalters ausgerichtet ist. Zur Betätigung des Schalters wird die mittels eines Schlüssels bewirkte Drehbewegung des Bartes des Zylinderschlosses über eine Mitnehmeranordnung auf den Schalter übertragen.In a key switch known from DE-C-2 208 019, an electrical rotary switch is arranged in a housing behind a cylinder lock so that the cylinder axis of the cylinder lock is aligned essentially coaxially with the axis of rotation of the switch. To actuate the switch, the rotary movement of the beard of the cylinder lock which is effected by means of a key is transmitted to the switch via a driver arrangement.

Wird bei einem derartigen bekannten Schlüsselschalter ein drehend betätigbarer Schalter, insbesondere ein Nockenschalter, mit einer Vielzahl von Schaltstellungen verwendet, so weist der bekannte Schlüsselschalter eine verhältnismäßig große Bautiefe auf, da zur Länge des Schalters die Länge des Zylinderschlosses hinzukommt.If a rotary switch, in particular a cam switch, with a plurality of switch positions is used in such a known key switch, the known key switch has a relatively large overall depth, since the length of the cylinder lock is added to the length of the switch.

Bei einem gattungsgemäßen Schlüsselschalter nach DE-U-70 20 833 ist der Bart des Schließzylinders zu einer Scheibe ergänzt, die über eine Triebkette in Antriebsverbindung mit einer auf der Drehachse des Schalters sitzenden Scheibe steht, die auf der der Betätigungsseite des Zylinderschlosses zugewandten Seite des Schalters angeordnet ist, wodurch sich eine große Baulänge der Gesamtanordnung ergibt. Außerdem läßt der bekannte Schlüsselschalter keine Drehung des Schließzylinders ohne gleichzeitge Schalterdrehung zu, wie sie jedoch erforderlich ist, um den Schlüssel auch in einer von der momentanen Schalterstellung unabhängigen Drehstellung des Schließzylinders abziehen zu können.In a generic key switch according to DE-U-70 20 833, the beard of the locking cylinder is supplemented to form a disk which is in drive connection via a drive chain with a disk located on the axis of rotation of the switch, which is on the side of the switch facing the actuating side of the cylinder lock is arranged, which results in a large length of the overall arrangement. In addition, the known key switch does not permit rotation of the locking cylinder without simultaneous switch rotation, as is necessary, however, in order to be able to remove the key in a rotational position of the locking cylinder which is independent of the current switch position.

Der Erfindung liegt die Aufgabe zugrunde, einen neuen Schlüsselschalter der eingangs genannten Art bereitzustellen, wobei bei einem möglichst kompakten Aufbau eine geringe Bautiefe erreicht wird.The object of the invention is to provide a new key switch of the type mentioned at the outset, with a small overall depth being achieved with the most compact possible construction.

Erfindungsgemäß wird diese Aufgabe durch die im Kennzeichen des Patentanspruchs angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of the patent claim.

Durch die erfindungsgemäße Anordnung des Betätigungsendes der Schalterwelle des Schalters auf der von der Betätigungsseite des Zylinderschlosses abgewandten Seite des Schalters und die Übertragung der Schwenkbewegung des Bartes des Zylinderschlosses über einen oder zwei Mitnehmerfinger auf eine Eingangswelle des Getriebes läßt sich das Zylinderschloß so neben dem Nockenschalter anordnen, daß die Bautiefe des Schlüsselschalters im wesentlichen nur noch von der Länge des Schalters bestimmt wird.Due to the arrangement according to the invention of the actuating end of the switch shaft of the switch on the side of the switch facing away from the actuating side of the cylinder lock and the transmission of the pivoting movement of the beard of the cylinder lock via one or two driver fingers to an input shaft of the transmission, the cylinder lock can be arranged next to the cam switch, that the depth of the key switch is essentially only determined by the length of the switch.

Dadurch, daß der Schalter mit seiner direkten Schaltseite, also mit dem Betätigungsende seiner Schalterwelle im Bereich der Rückseite des Schlüsselschalters angeordnet ist, kann auch das Getriebe für die Übertragung der Schwenkbewegung des Bartes auf die Schalterwelle zur Rückseite des Schlüsselschalters verlegt werden, so daß trotz der Anordnung des Zylinderschlosses neben dem Schalter eine kompakte Bauweise in der Tiefe ermöglicht wird.The fact that the switch is arranged with its direct switching side, i.e. with the actuating end of its switch shaft in the area of the back of the key switch, the gear for the transmission of the swiveling movement of the beard on the switch shaft to the back of the key switch, so that despite the Arrangement of the cylinder lock next to the switch allows a compact design in depth.

Um auch in der Breite bzw. Höhe eine möglichst kompakte Bauweise zu ermöglichen, ist bei einer ersten Weiterbildung der Erfindung vorgesehen, daß die Eingangswelle des Getriebes koaxial zur Zylinderachse des Zylinderschlosses angeordnet ist.In order to enable a construction that is as compact as possible in terms of width and height, it is provided in a first development of the invention that the input shaft of the transmission is arranged coaxially to the cylinder axis of the cylinder lock.

Dabei ist es zweckmäßig, wenn der bzw. die Mitnehmerfinger parallel und mit Abstand zur Zylinderachse angeordnet und an einer Stellscheibe befestigt ist/sind, die auf dem dem Zylinderschloß zugewandten Ende der Eingangswelle des Getriebes drehfest angeordnet ist.It is expedient if the driver finger (s) are arranged in parallel and at a distance from the cylinder axis and are / are attached to an adjusting disk which is arranged on the end of the input shaft of the transmission facing the cylinder lock in a rotationally fixed manner.

Um alle Mitnehmer ohne großen Aufwand auf der Eingangswelle des Getriebes montieren zu können, ist vorgesehen, daß die Eingangswelle als D-Profilwelle ausgebildet ist.In order to be able to mount all drivers on the input shaft of the transmission without great effort, it is provided that the input shaft is designed as a D-profile shaft.

Hierdurch wird erreicht, daß sowohl der bzw. die Mitnehmerfinger mit seiner/ihrer Stellscheibe als auch ein entsprechendes Getriebeglied einfach mit einer entsprechenden Bohrung zur Herstellung einer drehfesten, formschlüssigen Verbindung auf die Eingangswelle aufgesteckt werden können.This ensures that both the driver finger (s) with his / her adjusting disc and a corresponding gear member can simply be plugged onto the input shaft with a corresponding hole for producing a rotationally fixed, positive connection.

Bevorzugt ist bei der Erfindung vorgesehen, daß das Getriebe aus einem endlosen, flexiblen Zugmittel aus und mittels diesen vorzugsweise formschlüssig verbundenen Übertragungsrädern besteht, die drehfest auf der Eingangswelle bzw. der Schalterwelle angeordnet sind.It is preferably provided in the invention that the transmission consists of an endless, flexible traction means and by means of these preferably form-fittingly connected transmission wheels which are arranged in a rotationally fixed manner on the input shaft or the switch shaft.

Um dabei das Getriebe möglichst flach am Schalter anordnen zu können, ist bei einer vorteilhaften Weiterbildung der Erfindung vorgesehen, daß die Übertragungsräder in einer hinter dem Zylinderschloß und dem Schalter liegenden Ebene verlaufen, die sich senkrecht zur Achse des Zylinderschlosses bzw. des Schalters erstreckt.In order to be able to arrange the transmission as flat as possible on the switch, an advantageous further development of the invention provides that the transmission wheels run in a plane lying behind the cylinder lock and the switch, which extends perpendicular to the axis of the cylinder lock or the switch.

Eine andere vorteilhafte Weiterbildung zeichnet sich dadurch aus, daß das Zugmittel eine Kette ist und als Übertragungsräder ein erstes auf dem vom Zylinderschloß abgewandten Ende der Eingangswelle befestigtes Ritzel bzw. ein zweites Ritzel vorgesehen sind, das auf dem Betätigungsende der Schalterwelle angeordnet ist, wobei die beiden Ritzel über die Kette miteinander in Drehantriebsverbindung stehen.Another advantageous development is characterized in that the traction means is a chain and as a transmission wheels a first on the end facing away from the cylinder lock fixed pinion of the input shaft or a second pinion are provided, which is arranged on the actuating end of the switch shaft, the two pinions being in rotary drive connection with one another via the chain.

Hierdurch läßt sich trotz der flachen und kompakten Bauweise ein sicherer Kraftschluß stets gewährleisten.In this way, a secure frictional connection can always be guaranteed despite the flat and compact design.

Eine weitere vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, daß die Schalterwelle des Schalters sich durch diesen hindurcherstreckt und auf der von ihrem Betätigungsende abgewandten, indirekten Schaltseite des Schalters aus diesem herausragt und daß auf der indirekten Schaltseite eine Schaltstellungsanzeigevorrichtung mit der Schalterwelle verbunden ist.A further advantageous embodiment of the invention is characterized in that the switch shaft of the switch extends through it and protrudes from it on the indirect switching side of the switch facing away from its actuation end, and in that a switch position indicator is connected to the switch shaft on the indirect switching side.

Durch die Verwendung eines drehend betätigbaren Schalters, insbesondere eines Nockenschalters, mit einer durchgehenden Schalterwelle, wobei auf beiden Seiten des Nockenschalters ein entsprechender Wellenstumpf vorsteht, läßt sich die Verdrehung der Schalterwelle für die Anzeige der Schaltstellung des Schalters an der Vorderseite nutzen.By using a rotary switch, in particular a cam switch, with a continuous switch shaft, with a corresponding shaft end protruding on both sides of the cam switch, the rotation of the switch shaft can be used to display the switch position of the switch on the front.

Die Erfindung wird im folgenden beispielsweise anhand der Zeichnung näher erläutert, in dieser zeigt:

In den verschiedenen Figuren der Zeichnung sind einander entsprechende Bauteile mit gleichen Bezugszeichen bezeichnet.Corresponding components in the various figures of the drawing are identified by the same reference numerals.

Wie Fig. 1 zeigt, ist in einer Frontplatte 10 eines in einen Schaltschrank einbaubaren Schlüsselschalters ein Zylinderschloß 11 angeordnet. Unterhalb des Zylinderschlosses 11 sind auf einem Kreisbogen Bohrungen 13 vorgesehen, die in Bezug auf den Mittelpunkt des Kreisbogens mit einem Winkelabstand von 45° angeordnet sind, der dem Winkelabstand zwischen den einzelnen Schaltstellungen eines in Fig. 2 gezeigten Nockenschalters 18 entspricht.As shown in FIG. 1, a cylinder lock 11 is arranged in a front plate 10 of a key switch that can be installed in a control cabinet. Below the cylinder lock 11, holes 13 are provided on a circular arc, which are arranged at an angular distance of 45 ° with respect to the center of the circular arc, which corresponds to the angular distance between the individual switching positions of a cam switch 18 shown in FIG. 2.

Außerdem sind in der Frontplatte 10 Bohrungen 12 vorgesehen, um die Frontplatte 10 mit einer Halteplatte 14 in nicht dargestellter Weise zu verschrauben, wenn der Schlüsselschalter wie in Fig. 2 dargestellt, in eine Frontplatte 28 eines Schaltschranks eingesetzt ist.In addition, bores 12 are provided in the front plate 10 in order to screw the front plate 10 to a holding plate 14 in a manner not shown if the key switch is inserted into a front plate 28 of a control cabinet as shown in FIG. 2.

Die Halteplatte 14 weist einen sich senkrecht von der Frontplatte 10 weg erstreckenden Schenkel 14′ auf, an dem eine Winkelplatte 29 mit einem ersten Schenkel 29′ befestigt ist. Ein zweiter Schenkel 29˝ der Winkelplatte 29 ist im wesentlichen parallel zur Halteplatte 14 angeordnet und fest mit einer Querstütze 30 verbunden, die mit ihrem von der Winkelplatte 29 abgewandten Ende an der Halteplatte 14 befestigt ist.The holding plate 14 has a leg 14 'extending perpendicularly from the front plate 10', to which an angle plate 29 is fastened with a first leg 29 '. A second leg 29˝ of the angle plate 29 is arranged substantially parallel to the holding plate 14 and firmly connected to a transverse support 30 which is fastened to the holding plate 14 with its end facing away from the angle plate 29.

In Fig. 2 unterhalb der Querstütze 30 ist als drehend betätigbarer Schalter ein Nockenschalter 18 mit vorzugsweise einer Vielzahl von Schaltstellungen angeordnet, der mit seiner direkten Schaltseite an der Winkelplatte 29 befestigt ist. Der Nockenschalter 18 weist dabei eine durchgehende Schalterwelle 19 auf, die sich mit ihrem aus dem Nockenschalter 18 herausragenden Betätigungsende 21 durch eine entsprechende Bohrung in der Winkelplatte 29 hindurcherstreckt. Mit ihrem anderen Ende steht die Schalterwelle 19 von der indirekten Schaltseite des Nockenschalters 18 vor und trägt eine Schaltstellungsanzeigevorrichtung 27, die hinter den Bohrungen 13 in der Frontplatte 10 angeordnet ist und mit diesen zusammenwirkt, um die jeweilige Schaltstellung des Nockenschalters 18 anzuzeigen.In Fig. 2 below the cross support 30, a cam switch 18 is arranged as a rotatably actuated switch, preferably with a plurality of switching positions, which with its direct switching side is attached to the angle plate 29. The cam switch 18 has a continuous switch shaft 19 which, with its actuating end 21 protruding from the cam switch 18, extends through a corresponding bore in the angle plate 29. At its other end, the switch shaft 19 protrudes from the indirect switching side of the cam switch 18 and carries a switch position indicator device 27, which is arranged behind the bores 13 in the front plate 10 and interacts with them to indicate the respective switch position of the cam switch 18.

Über dem Nockenschalter 18 ist das Zylinderschloß 11 so angeordnet, daß seine Zylinderachse 15 parallel zur Schalterwelle 19 verläuft. Das Zylinderschloß 11 ist dabei mit einer Schraube 31 an der Querstütze 30 befestigt.The cylinder lock 11 is arranged above the cam switch 18 so that its cylinder axis 15 runs parallel to the switch shaft 19. The cylinder lock 11 is fastened with a screw 31 to the cross support 30.

Das Zylinderschloß 11 erstreckt sich so durch eine Ausnehmung in einem ersten Schenkel 32′, einer U-förmigen Klammer 32, die an dem waagerechten Schenkel 29′ der Winkelplatte 29 befestigt ist, daß ein Bart 16 des Zylinderschlosses 11 von der Frontplatte 10 aus gesehen hinter dem ersten Schenkel 32′ verschwenkbar angeordnet ist. Auf diese Weise wird verhindert, daß das Zylinderschloß 11 auch bei gelöster Schraube 31 nur mit Hilfe eines entsprechenden Schlüssels aus dem Schlüsselschalter entnommen werden kann.The cylinder lock 11 extends through a recess in a first leg 32 ', a U-shaped bracket 32 which is attached to the horizontal leg 29' of the angle plate 29 that a beard 16 of the cylinder lock 11 seen from the front plate 10 behind the first leg 32 'is pivotally arranged. In this way it is prevented that the cylinder lock 11 can only be removed from the key switch even with the screw 31 loosened with the aid of an appropriate key.

In einem zweiten, hinteren Schenkel 32˝ der Klammer 32 ist eine als D-Profil-Welle ausgebildete Eingangswelle 22 eines Getriebes 20 mit ihrem dem Zylinderschloß 11 zugewandten Ende gelagert. Das getriebeseitige Ende der Eingangswelle 22 ist in einer entsprechenden Lagerbohrung im senkrecht angeordneten Schenkel 29˝ der Winkelplatte 29 gelagert. Auf dem dem Zylinderschloß 11 zugewandten Ende der Eingangswelle 22 ist innerhalb der Klammer 32 eine Stellscheibe 23 drehfest aufgesteckt und z.B. mittels einer selbsthaltenden Federscheibe 33 gegen Abziehen gesichert. In einem radialen Abstand zur Drehachse der Stellscheibe 23 ist an dieser ein Mitnehmerfinger 17 vorgesehen, der parallel zur Zylinderachse 15 angeordnet ist und der sich so zum Zylinderschloß 11 erstreckt, daß er mit dem Bart 16 des Zylinderschlosses 11 in Eingriff bringbar ist, um die Schwenkbewegung des Bartes 16 auf die Eingangswelle 22 zu übertragen.In a second, rear leg 32˝ of the bracket 32, an input shaft 22 of a transmission 20 designed as a D-profile shaft is mounted with its end facing the cylinder lock 11. The gear end of the input shaft 22 is mounted in a corresponding bearing bore in the vertically arranged leg 29 Sch of the angle plate 29. On the end of the input shaft 22 facing the cylinder lock 11, an adjusting disk 23 is rotatably fixed within the bracket 32 attached and secured against pulling off, for example by means of a self-retaining spring washer 33. At a radial distance from the axis of rotation of the adjusting disk 23, a driving finger 17 is provided on the latter, which is arranged parallel to the cylinder axis 15 and which extends to the cylinder lock 11 in such a way that it can be brought into engagement with the beard 16 of the cylinder lock 11 by the pivoting movement to transfer the beard 16 to the input shaft 22.

Auf dem getriebeseitigen Ende der Eingangswelle 22 ist ein erstes Ritzel 24 des Getriebes 20 drehfest angeordnet und z.B. durch eine selbsthemmende Federscheibe 34 gegen Abrutschen gesichert. Das erste Ritzel 24 wirkt mit einer endlosen Kette 26 zusammen, die zur Übertragung einer Drehbewegung auf die Schalterwelle 19 mit einem zweiten Ritzel 25 des Getriebes 20 zusammenwirkt, das auf das Betätigungsende 21 der Schalterwelle 19 drehfest aufgesetzt ist.On the transmission end of the input shaft 22, a first pinion 24 of the transmission 20 is rotatably arranged and e.g. secured against slipping by a self-locking spring washer 34. The first pinion 24 interacts with an endless chain 26, which cooperates with a second pinion 25 of the transmission 20, which is mounted on the actuating end 21 of the switch shaft 19 in a rotationally fixed manner, to transmit a rotary movement to the switch shaft 19.

Um die drehfeste Verbindung zwischen dem zweiten Ritzel 25 und der Schalterwelle 19 einfach herstellen zu können, weist die Schalterwelle 19 einen D-Profil-förmigen Abschnitt auf, dessen Querschnitt einer entsprechenden D-förmigen Bohrung im zweiten Ritzel 25 entspricht. Um das zweite Ritzel 25 auf der Schalterwelle 19 zu halten, ist wiederum eine Federscheibe 35 vorgesehen, die auf die Schalterwelle 19 selbstklemmend aufgesteckt ist.In order to be able to easily establish the rotationally fixed connection between the second pinion 25 and the switch shaft 19, the switch shaft 19 has a D-profile-shaped section, the cross section of which corresponds to a corresponding D-shaped bore in the second pinion 25. In order to hold the second pinion 25 on the switch shaft 19, a spring washer 35 is again provided, which is plugged onto the switch shaft 19 in a self-locking manner.

Der als Einbauschalter beschriebene Schlüsselschalter kann als Aufbauschalter auch in einem eigenen Gehäuse angeordnet sein.The key switch described as a built-in switch can also be arranged in a separate housing as a built-in switch.

Um den Nockenschalter 18 zu betätigen, wird der Bart 16 mit einem entsprechenden Schlüssel aus seiner Stellung, in der der Schlüssel aus dem Zylinderschloß 11 abziehbar ist, so weit verdreht, bis er am Mitnehmerfinger 17 anliegt und diesen bei seiner weiteren Schwenkbewegung mitnimmt. Dabei wird die Schwenkbewegung des Bartes 16 über den Mitnehmerfinger 17 auf die Eingangswelle 22 des Getriebes 20 übertragen, so daß die Schalterwelle 19 über das Getriebe 20 entsprechend verdreht wird, bis eine gewünschte Schalterstellung erreicht ist, die mittels der Schaltstellungsanzeigevorrichtung 17 über die Bohrungen 13 in der Frontplatte 10 des Schlüsselschalters sichtbar gemacht wird. Um den Schalter zurückzuschalten, kann dann der Bart 16 in der anderen Richtung verschwenkt werden, bis er den Mitnehmerfinger 17 von der anderen Seite beaufschlagt und mitnimmt.In order to actuate the cam switch 18, the beard 16 is rotated with a corresponding key from its position in which the key can be removed from the cylinder lock 11 until it rests on the driving finger 17 and takes this with him during his further pivoting movement. The pivoting movement of the beard 16 is transmitted via the driver finger 17 to the input shaft 22 of the transmission 20, so that the switch shaft 19 is rotated accordingly via the transmission 20 until a desired switch position is reached, which by means of the switch position indicator 17 via the holes 13 in the front panel 10 of the key switch is made visible. In order to switch the switch back, the beard 16 can then be pivoted in the other direction until it acts on the driver finger 17 from the other side and takes it along.

Als Nockenschalter 18 können Nockenschalter verwendet werden, die je nach Einsatzgebiet eine unterschiedliche Zahl von Drehschaltstellungen aufweisen. Dabei können auch die Winkelabstände zwischen den einzelnen Schaltstellungen variiert werden.Cam switches can be used as cam switches 18, which have a different number of rotary switch positions depending on the area of application. The angular distances between the individual switching positions can also be varied.

Da der Mitnehmerfinger vom Bart 16 über einen Winkelbereich von etwa 300° verdreht werden kann, ergibt sich ein entsprechender Schaltstellungsverlauf für den Nockenschalter 18, wenn das Getriebe wie im dargestellten Ausführungsbeispiel ein Übersetzungsverhältnis von 1 zu 1 aufweist. Um auch Nockenschalter 18 mit einem Schaltstellungsverlauf von 360° betätigen zu können, ist es möglich, ein Untersetzungsgetriebe zu verwenden, das so ausgelegt ist, daß eine Verdrehung des Mitnehmerfingers 17 um 300° eine Verdrehung der Schalterwelle 19 um 360° oder mehr bewirkt.Since the driver finger 16 of the beard 16 can be rotated over an angular range of approximately 300 °, a corresponding shift position curve results for the cam switch 18 if the transmission has a transmission ratio of 1 to 1 as in the exemplary embodiment shown. In order to also be able to actuate cam switch 18 with a switching position curve of 360 °, it is possible to use a reduction gear which is designed such that a rotation of the driving finger 17 by 300 ° causes a rotation of the switch shaft 19 by 360 ° or more.

Wird, wie in Fig. 1 dargestellt, im Schlüsselschalter ein drehend betätigbarer Schalter mit wenigen Schaltstellungen und einem Schaltstellungsverlauf über z.B. 135° verwendet, so kann an der Stellscheibe 23 ein weiterer nicht dargestellter Mitnehmerfinger parallel zum ersten Mitnehmerfinger 17 angeordnet werden, um den Schwenkweg des Bartes 16 beim Schaltrichtungswechsel zu verkürzen. Ein derartiger zusätzlicher Mitnehmerfinger kann auch für andere spezielle Schaltaufgaben vorgesehen sein.If, as shown in Fig. 1, a rotary switch with a few switch positions and a switch position course over, for example, 135 ° is used in the key switch, a further driver finger, not shown, can be arranged parallel to the first driver finger 17 on the adjusting plate 23 in order to pivot the path of the Bartes 16 at Shorten switching direction change. Such an additional driver finger can also be provided for other special switching tasks.
