Description

Die Erfindung bezieht sich auf einen Drehschalter mit für die Drehbewegung relevanten Komponenten, insbesondere mit einem Betätigungselement und einem drehbaren Innenteil, über die durch Umsetzung der Drehbewegung in eine Translationsbewegung das Öffnen und Schließen von Schaltkontakten des Drehschalters erfolgt.The invention relates to a rotary switch for the Rotational movement relevant components, especially with a Actuator and a rotatable inner part, through which by converting the rotary movement into a translational movement the opening and closing of switching contacts of the rotary switch he follows.

Derartige Drehschalter gehören seit längerer Zeit zum Lieferprogramm von Elektrounternehmen. In Verbindung mit der Nutzung von Drehschaltern gibt es Anwendungsfälle, z.B. bei Etagenparksystemen, wo sichergestellt sein muß, daß ein Schaltvorgang bzw. ein Abziehen des Schlüssels bei Schlüsseldrehschaltern nur unter bestimmten Bedingungen erfolgen kann. Es muß dabei gewährleistet werden, daß eine Freigabe des Schalters zum Zurückschalten auf die Null- und damit auch Schlüsselabzugs-Stellung erst möglich ist, wenn die erforderlichen Bedingungen erfüllt sind, was durch eine entsprechende Information, z.B. über elektrischen Strom, an den Drehschalter gegeben wird.Such rotary switches have been part of the delivery program for a long time of electrical companies. In connection with the use There are applications for rotary switches, e.g. for multi-storey parking systems, where it must be ensured that a switching operation or removing the key with key rotary switches can only be done under certain conditions. It it must be ensured that the switch is released to switch back to the zero and thus key withdrawal position is only possible if the necessary Conditions are met, which is indicated by appropriate information, e.g. via electrical current, given to the rotary switch becomes.

Bisher standen zur Erfüllung derartiger Forderungen nur relativ teure, komplizierte und unflexible Lösungen zur Verfügung. Es wurden bisher hierfür elektromagnetische Abzugs- bzw. Einführsperren für Schlösser bzw. Schließzylinder eingesetzt, die direkt auf die Schließstifte bzw. auf den Schlüssel wirken und Bestandteil des Schloßkörpers sind.So far, only relative have been available to meet such demands expensive, complicated and inflexible solutions available. So far, electromagnetic trigger or Insertion locks used for locks or lock cylinders, the directly on the locking pins or on the key act and are part of the lock body.

Daher liegt der Erfindung die Aufgabe zugrunde, einen Drehschalter auf einfache Weise derart zu modifizieren, daß ein Zurückschalten auf die Null- und auch Schlüsselabzugs-Stellung abhängig von einer mit einem elektrischen Stromkreis erfaßten Bedingung gesperrt werden kann.The invention is therefore based on the object of a rotary switch to modify in such a simple way that a Switch back to the zero and key withdrawal position depending on one with an electrical circuit recorded condition can be locked.

Die Lösung der Aufgabe besteht darin, daß ein Sperrelement mit einem elektromagnetisch derart in seiner Bewegung beeinflußbaren Bolzen vorgesehen ist, daß dieser sich in eine die Drehbewegung sperrende oder bei erfolgter Drehblockierung in eine diese freigebende Position bewegt.The solution to the problem is that a locking element with an electromagnetically so influenceable in its movement Bolt is provided that this is in a Locking rotational movement or in case of rotation blocking in a position that releases this.

Eine vorteilhafte Ausführungsform besteht, wenn das Sperrelement einen elektromagnetischen Antrieb mit einem Anker aufweist, der mit dem Bolzen in Verbindung steht.An advantageous embodiment is when the locking element has an electromagnetic drive with an armature, which is connected to the bolt.

Als besonders vorteilhaft hat es sich erwiesen, wenn der Bolzen zumindest teilweise aus ferromagnetischem Material ausgeführt ist und als Anker dient.It has proven to be particularly advantageous if the bolt at least partially made of ferromagnetic material is and serves as an anchor.

Eine einfache, integrierte Stellungsabfrage für den Bolzen ist gegeben, wenn das Sperrelement Quittierkontakte aufweist, die abhängig von der Position des Ankers geöffnet oder geschlossen werden.A simple, integrated position query for the bolt is given if the blocking element has acknowledgment contacts, which opened or closed depending on the position of the anchor become.

Um die zur Sperrung erforderliche Kraftübertragung zu erreichen, ist es besonders vorteilhaft, wenn der Bolzen mit einer der für die Drehbewegung relevanten Komponenten formschlüssig verbindbar ist.In order to achieve the power transmission required for locking, it is particularly advantageous if the bolt with a of the components relevant to the rotary movement is connectable.

Eine besonders preisgünstige und flexible Lösung erhält man, wenn das Sperrelement auf den Drehschalter aufschnappbar ist.You get a particularly inexpensive and flexible solution if the locking element can be snapped onto the rotary switch.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert.An embodiment of the invention is described below a drawing explained in more detail.

In der Zeichnung ist ein Ausschnitt eines Drehschalters 1, hier insbesondere eines Schlüsseldrehschalters dargestellt, der mit einem Sperrelement 2 verbunden ist. Von dem für den Fronttafeleinbau geeigneten Drehschalter 1 ist der frontseitig liegende Betätigungszylinder 3 mit einem Schloß 4, ein sich an sich anschließendes zylindrisches Gehäuseteil 5 sowie ein drehbares Innenteil 6 gezeigt, das mit dem Betätigungszylinder 3 in Verbindung steht. Das im wesentlichen aus einem Gehäuse 7 mit einem Elektromagneten 8 und zugehörigen Anschlußkontakten 9, einem Bolzen 10 und Quittierkontakten 11 bestehende Sperrelement 2 ist auf das Gehäuseteil 5 endseitig aufgeschnappt. Der mit dem Anker 12 des Elektromagneten 8 verbundene Bolzen 10 ragt in das Gehäuseteil 5 hinein. Er ist wie der Anker 12 in seiner Längsachse derart verschiebbar, das sich sein konturiertes Ende formschlüssig mit dem Innenteil 6 verbindet und auf diese Weise die Drehbewegung des Drehschalters 1 sperrt. Alternativ ist es auch denkbar durch Eingriff des Bolzens 10, z.B. am Betätigungszylinder 3, die Drehbewegung zu sperren.In the drawing is a section of a rotary switch 1, here shown in particular a key rotary switch, which is connected to a locking element 2. From that for that The suitable rotary switch 1 on the front panel is the one on the front lying actuating cylinder 3 with a lock 4, a adjoining cylindrical housing part 5 and a rotatable inner part 6 shown with the actuating cylinder 3 communicates. That essentially from one Housing 7 with an electromagnet 8 and associated connecting contacts 9, a bolt 10 and acknowledgment contacts 11 existing locking element 2 is on the end of the housing part 5 snapped. The one with the armature 12 of the electromagnet 8th connected bolt 10 protrudes into the housing part 5. He is as the anchor 12 is displaceable in its longitudinal axis, that its contoured end is form-fitting with the inner part 6 connects and in this way the rotary movement of the Rotary switch 1 locks. Alternatively, it is also conceivable Engagement of the bolt 10, e.g. on the actuating cylinder 3, the Lock rotary motion.

Die formschlüssige Verbindung zwischen dem Bolzen 10 und dem Innenteil 6 erfolgt bei einer vorliegenden Ausführungsform über eine Verzahnung 13.The positive connection between the bolt 10 and the Inner part 6 takes place in a present embodiment via a toothing 13.

Je nach Anwendungsfall wird der Bolzen 10 bei Stromfluß durch den Elektromagneten 8 entgegen einer Rückhaltefeder 14 nach oben oder entgegen einer Andruckfeder nach unten verschoben, um auf diese Weise die Drehbewegung des Innenteils 6 zu sperren oder freizugeben. Der Stromfluß ist dabei mit einem bestimmten Zustand verbunden, bei dem die Rückstellung des Drehschalters 1 in seine Null- bzw. Schlüsselabzugs-Stellung zulässig oder verhindert sein soll.Depending on the application, the bolt 10 is through when current flows the electromagnet 8 against a retaining spring 14 moved up or against a pressure spring, in order to block the rotational movement of the inner part 6 or release. The current flow is with a certain one State connected in which the provision of the Rotary switch 1 in its zero or key withdrawal position should be permitted or prevented.

Die Quittierkontakte 11 werden hier von dem Bolzen 10 positionsabhängig geschlossen, wodurch eine einfache Stellungsabfrage des Sperrelements 2 ermöglicht wird. The acknowledgment contacts 11 are here dependent on the position of the bolt 10 closed, making a simple position query of the locking element 2 is made possible.

Alternativ zur oben beschriebenen Lösung kann der Bolzen 10 selbst als ein verlängerter Anker ausgeführt sein, der dann zumindest in seinem Funktionsbereich als Anker aus ferromagnetischem Material besteht.As an alternative to the solution described above, the bolt 10 itself be designed as an elongated anchor, which then at least in its functional area as an armature made of ferromagnetic Material exists.

Die zuvor beschriebene Ausführung des Drehschalters 1 hat den Vorteil, daß der elektrische Bereich komplett geschützt hinter der Fronttafel bzw. in einem Gehäuse verbleibt, was eine erhebliche Vereinfachung zur Einhaltung bestimmter Schutzarten darstellt.The previously described embodiment of the rotary switch 1 has the Advantage that the electrical area is completely protected behind the front panel or in a housing remains, what a considerable simplification to comply with certain protection types represents.

Weiterhin besteht der Vorteil dieser Lösung darin, daß jeder Drehantrieb, ob Schloß-, auch Schließanlage, Knebel-, Schwenkhebel-, Drehknopf-Antrieb etc. mit der Drehsperre, auch nachträglich im montierten Zustand, ausgestattet werden kann.Another advantage of this solution is that everyone Rotary drive, whether lock or locking system, toggle, Swivel lever, rotary knob drive etc. with the turnstile, can also be retrofitted in the assembled state can.
