Description

Die Erfindung bezieht sich auf einen Drehschalter mit für die Drehbewegung relevanten Komponenten in einem ersten Gehäuse, insbesondere mit einem Betätigungselement und einem drehbaren Innenteil, über die das Öffnen und Schließen von Schaltkontakten des Drehschalters erfolgt.The invention relates to a rotary switch with for Rotary motion relevant components in a first housing, in particular with an actuating element and a rotatable Inner part, about the opening and closing of switch contacts of the rotary switch takes place.

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 some time of electrical companies. In connection with the use of rotary switches there are applications, e.g. in storey parking systems, where it must be ensured that a switching operation or a removal of the key with key rotary switches only under certain conditions. It must be ensured that a release of the switch To switch back to the zero and thus key withdrawal position only possible if the required Conditions are met, which is supported 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, the fulfillment of such demands were only relative expensive, complicated and inflexible solutions available. For this purpose, electromagnetic or insertion locks used for locks or lock cylinders, directly on the locking pins or on the key act and are part of the lock body.

Die DE 195 25 083 A1 offenbart einen elektrischen Sperrschalter, bei dem zwischen einem Drehschloß und einem Zündschloßmechanismus eine elektromagnetisch betriebene Blockiereinrichtung als integraler Bestandteil eingebaut ist. DE 195 25 083 A1 discloses an electric lock switch, in which between a rotary lock and an ignition lock mechanism an electromagnetically operated blocking device is incorporated as an integral part.

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, a rotary switch in a simple way to modify such that Switch back to the zero and key withdrawal position depending on one with an electrical circuit entered condition can be locked.

Die Lösung der Aufgabe besteht darin, daß an dem Drehschalter ein Sperrelement mit einem eigenen zweiten Gehäuse angekoppelt ist, das einen Elektromagneten und einen durch diesen beeinflussbaren, in seiner Längsachse verschieblichen Bolzen aufweist, der abhängig von seiner Position die Drehbewegung sperrt oder freigibt.The solution of the problem is that on the rotary switch a blocking element coupled with its own second housing is that one electromagnet and one through this one influenceable, displaceable in its longitudinal axis bolt which, depending on its position, the rotational movement locks or releases.

Als besonders vorteilhaft hat es sich erwiesen, wenn der Bolzen zumindest teilweise aus ferromagnetischem Material ausgeführt ist und als Anker dient.It has proved to be particularly advantageous when 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 are opened or closed depending on the position of the armature 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 blocking, It is particularly advantageous if the bolt with a the relevant components for the rotary motion form-fitting is connectable.

Eine besonders preisgünstige und flexible Lösung erhält man, wenn das Sperrelement auf den Drehschalter aufgeschnappt ist.A particularly inexpensive and flexible solution is obtained, when the blocking element is snapped onto the rotary switch.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert.An embodiment of the invention will be 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, shown here in particular a key rotary switch, which is connected to a blocking element 2. From that for the Front panel installation suitable rotary switch 1 is the front lying actuating cylinder 3 with a lock 4, a itself to subsequent cylindrical housing part 5 and a rotatable inner part 6 shown with the actuating cylinder 3 communicates. This essentially consists of one Housing 7 with an electromagnet 8 and associated connection contacts 9, a bolt 10 and Acknowledge contacts 11th existing blocking element 2 is on the housing part 5 end snapped. The with the armature 12 of the electromagnet eighth connected bolt 10 protrudes into the housing part 5. He is as the armature 12 so displaceable in its longitudinal axis, that its contoured end form-fitting with the inner part 6 connects and in this way the rotational movement of the Rotary switch 1 locks. Alternatively, it is also possible through 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 in current flow through the electromagnet 8 against a retaining spring 14 after moved down or against a pressure spring down, to lock in this way the rotational movement of the inner part 6 or release. The current flow is with a certain State associated with the provision of the Rotary switch 1 in its zero or key withdrawal position allowed or prevented.

Die Quittierkontakte 11 werden hier von dem Bolzen 10 positionsabhängig geschlossen, wodurch eine einfache Stellungsabfrage des Sperrelements 2 ermoglicht wird. The acknowledgment contacts 11 are position-dependent here by the bolt 10 closed, creating 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 as an extended anchor, then the at least in its functional area as an anchor 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 completely protected behind the front panel or in a housing remains what a considerable simplification for compliance with certain types of protection 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.Furthermore, the advantage of this solution is that everyone Rotary drive, whether lock, also locking system, toggle, Pivot lever, knob drive etc. with turnstile, also be retrofitted in the assembled state can.
