Abstract

The switching cylinder consists of a cylinder core, which is provided in cylinder housing and can be rotated using a mechanically coded key between an off-position and a switching position. The switch can be operated by an allocated contact at the cylinder core. A locking unit is provided in the cylinder housing stopping the key to be pulled out when the key is in the switching position. An independent claim is also provided for a switching cylinder having a key with a mechanical coding and an additional electronic coding.

Description

Die Erfindung betrift einen Schaltzylinder für elektrisch mittels eines Schalters ein- und ausschaltbare Geräte oder Anlagen, bestehend aus einem Zylinderkern, der mittels eines mechanisch codierten Schlüssels zwischen einer Nullstellung und einer Schaltstellung in einem Zylindergehäuse drehbar gelagert ist, wobei der Schalter durch einen zugeordneten Kontakt am Zylinderkern betätigbar ist, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a shift cylinder for electric by means of a switch switchable devices or systems consisting of a cylinder core, which by means of a mechanically coded key rotatable between a zero position and a switching position in a cylinder housing is mounted, the switch by an associated contact Can be operated on the cylinder core is, according to the preamble of claim 1.

Derartige Schaltzylinder sind aus der Praxis allgemein bekannt und dienen dazu, die angeschlossenen Geräte oder Anlage nur durch berechtigte Personen in Betrieb setzen zu lassen.Such switching cylinders are made generally known in practice and serve the connected equipment or put the system into operation only by authorized persons to let.

Vergleicht man diese Schaltzylinder mit normalen Schließzylindern, wie sie zum Öffnen und Verschließen von Türen verwendet werden, so ist beiden gemeinsam, dass sie in zwei Schlüsselstellungen ein Herausziehen des Schlüssels zulassen. Bezogen auf das Beispiel Türschloss bedeutet dies, man kann den Schlüssel sowohl in der Stellung abziehen, in der die Tür verschlossen ist, wie auch in der Stellung, in der die Tür nicht verschlossen ist. Überträgt man dies auf die Schaltzylinder, so bedeutet dies, dass der Schlüssel sowohl in der Schaltstellung wie auch der Nullstellung abziehbar ist. Während dies für die Nullstellung richtig und notwendig ist, ergeben sich für die Schaltstellung erhebliche Nachteile. Würde nämlich der Schlüssel in der Schaltstellung herausgezogen werden, so bliebe das zugeordnete Gerät oder die gesamte angeschlossene Anlage in Betrieb. Unter bestimmten Umständen oder spezifischen Geräten oder Anlagen kann dies erhebliche Gefahren bedeuten.If you compare these shift cylinders with normal locking cylinders, how to open it and closing of doors used, both have in common that they are in two key positions pulling out the key allow. Based on the example of a door lock, this means one can the key pull off in the position in which the door is locked as well in the position in which the door is not closed. You transmit this on the shift cylinder, it means that the key is both is removable in the switch position as well as the zero position. During this for the Zero position is correct and necessary for the switch position significant disadvantages. Would namely the key are pulled out in the switch position, the assigned one would remain Device or the entire connected system is in operation. Under certain circumstances or specific devices or This can pose significant dangers to plants.

Aufgabe der Erfindung ist es daher, den Schaltzylinder so auszubilden, dass der Schlüssel in der Schaltstellung nicht abziehbar ist.The object of the invention is therefore train the shift cylinder so that the key is in the shift position is not removable.

Zusätzlich soll die Möglichkeit geschaffen werden, eine Überwachung , insbesondere Fernüberwachung, des Schaltzylinders vorzunehmen.In addition, the possibility should surveillance , especially remote monitoring, of the shift cylinder.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1 bzw. den Merkmalen des Anspruchs 4.This task is solved with the Features of claim 1 or the features of claim 4.

Kerngedanke der Erfindung ist der Einsatz einer Sperreinrichtung, die im Zylindergehäuse angeordnet ist, und die den Schlüssel gegen ein Herausziehen in der Schaltstellung sichert.The core idea of the invention is Use of a locking device arranged in the cylinder housing and that's the key secures against pulling out in the switch position.

Vorzugsweise ist diese Sperreinrichtung als elektrisch betätigbare Verriegelung ausgebildet, beispielsweise in Form eines Magnetankers.This locking device is preferably as electrically operated Lock formed, for example in the form of a magnet armature.

Besonders vorteilhaft ist die im Anspruch 4 angegebene Merkmalskombination. Hierbei wird mit einem zusätzlich zur mechanischen Codierung, elektronisch codierten Schlüssel gearbeitet, der mit einem in das Zylindergehäuse integrierten Lesekopf zusammenwirkt.The im is particularly advantageous Claim 4 specified combination of features. Here, with a additionally for mechanical coding, electronically coded keys worked, the one in the cylinder housing integrated reading head interacts.

Diese Ausgestaltung eröffnet einerseits die Möglichkeit, bestehende Schaltzylinder mit wenig Aufwand zu modifizieren, und zwar durch Anbau der Zylinderverlängerung mit einer entsprechenden Verriegelung für den Schlüssel. Austauschbar wäre dann lediglich der Schlüssel, der aber nur hinsichtlich der elektronischen Codierung zu ergänzen ist. Andere Einrichtungen, die nur die mechanische Codierung des Schlüssels ausnutzen, könnten unverändert bleiben.This configuration opens up on the one hand the possibility, to modify existing shift cylinders with little effort, and by fitting the cylinder extension with a corresponding one Lock for the key. It would then be interchangeable just the key, but which can only be supplemented with regard to electronic coding. Other devices that only use the mechanical coding of the key could unchanged stay.

Zusätzlich ermöglicht der elektronische Lesekopf dann aber auch eine Fernüberwachung des Schaltzylinders, dh. beispielsweise kann auch einem berechtigten Schlüssel die Betätigungsbefugniss entzogen werden.In addition, the electronic read head enables then remote monitoring of the shift cylinder, ie. for example, an authorized one key the power to operate be withdrawn.

Die Erfindung soll nachfolgend an einem in der Zeichnung dargestellten Ausführungsbeispiel erläutert werden.The invention is intended to: an embodiment shown in the drawing will be explained.

Dabei ist der Schaltzylinder vereinfacht und teilweise geschnitten in zwei Zuständen dargestellt, und zwar inThe shift cylinder is simplified and shown partially cut in two states, namely in

1 in der Schaltstellung und in 1 in the switch position and in

2 in der Nullstellung. 2 in the zero position.

Der Schaltzylinder besteht aus einem Zylindergehäuse 1, das durch eine Gehäuseverlängerung 2 ergänzt ist. In dem Zylindergehäuse 1 befindet sich der drehbare Zylinderkern 3. Die Kernverlängerung 8 ist in der Gehäuseverlängerung 2 angeordnet und steht an einem Ende mit einem Schalter 4 in Kontakt, der zum Ein- und Ausschalten eines nicht dargestellten Gerätes oder einer Anlage dient.The shift cylinder consists of a cylinder housing 1 by a housing extension 2 is added. In the cylinder housing 1 is the rotatable cylinder core 3 , The core extension 8th is in the housing extension 2 arranged and stands at one end with a switch 4 in contact, which is used to switch a device or system, not shown, on and off.

Wie aus der Stirnansicht des Schaltzylinders in den beiden Figuren ersichtlich, kann der Schaltzylinder zwei Schaltstellungen einnehmen, und zwar eine Nullstellung (2) und die eigentliche Schaltstellung (1), in der das angeschlossene Gerät oder die Anlage betriebsbereit ist.As can be seen from the front view of the switching cylinder in the two figures, the switching cylinder can assume two switching positions, namely a zero position ( 2 ) and the actual switch position ( 1 ) in which the connected device or system is ready for operation.

In der Schaltstellung ist der Magnetanker bzw. dessen eigentlicher Anker 5 in Ausnehmungen 6 und 7 in der Kernverlängerung 8 bzw. im Schlüssel 9 abgesenkt, so dass weder der Kern gedreht noch der Schlüssel herausgezogen werden kann. Das Herausziehen des Schlüssels geht erst wieder, wenn der Zylinderkern in die Nullstellung gedreht worden ist.The magnetic armature or its actual armature is in the switch position 5 in recesses 6 and 7 in the core extension 8th or in the key 9 lowered so that the core cannot be turned and the key cannot be removed. The key can only be removed when the cylinder core has been turned to the zero position.
