Abstract

A lock barrel has a rotatably-mounted cylinder core in a barrel housing and provided with housing- and core-pins functioning in conjunction with a mechanically coded key, and with agreement of the coding, rotation of the cylinder core for carrying out a locking process is possible. Rotation of the cylinder core can be electromechanically blocked and the electromechanical blocking can be released via an external switching process.

Description

Die Erfindung bezieht sich auf einen Schließzylinder, mit einem im Zylindergehäuse drehbar gelagerten Zylinderkern, mit Gehäuse- und Kernstiften, die mit einem mechanisch codierten Schlüssel zusammenwirken und bei übereinstimmender Codierung die Drehung des Zylinderkerns zur Ausführung des Schließvorganges zulassen.The invention relates to a lock cylinder, with a cylinder housing rotatably mounted in the cylinder core, with housing and core pins, which cooperate with a mechanically coded key and allow for matching coding the rotation of the cylinder core to perform the closing operation.

Derartige Schließzylinder sind weit verbreitet. Sie können beispielsweise der Sicherung von Wohnungen, Häusern, Autos, Fahrzeugen, Möbeln, öffentlich aufgestellten Apparaten, Briefkästen usw. dienen.Such lock cylinders are widely used. For example, they can be used to secure homes, houses, cars, vehicles, furniture, public displays, mailboxes, etc.

Die mechanische Codierung des Schlüssels kann beispielsweise aus einem Kerben aufweisenden Profil in der Schlüsselbrust bestehen.The mechanical coding of the key, for example, consist of a notch having profile in the key-chest.

Bei in den Schlüsselkanal des Schließzylinders eingestecktem, passenden Schlüssel bewirkt die Codierung eine Verschiebung der Stifte, so dass sich bei allen Stiften ein Abgleich an der Trennebene zwischen Zylindergehäuse und Zylinderkern ergibt. Damit ist ein Drehen des Zylinderkerns im Zylindergehäuse zur Ausführung des Schließvorganges möglich. Der Schlüssel ist im Allgemeinen in mehrfacher Kopie vorhanden. Befinden sich diese Kopien im Besitz mehrerer Personen, können diese getrennt voneinander den Schließvorgang auslösen und Zutritt zu der abgeschlossenen Einheit erlangen. Nachteilig hieran ist, dass Schlüsselbesitzer der Zugang zu der abgeschlossenen Einheit jederzeit möglich ist.When inserted into the key channel of the lock cylinder, matching key causes the coding displacement of the pins, so that there is an adjustment at the separation level between the cylinder housing and cylinder core at all pins. Thus, a rotation of the cylinder core in the cylinder housing for performing the closing operation is possible. The key is generally available in multiple copies. If these copies are owned by several persons, they can trigger the closing process separately and gain access to the completed unit. The disadvantage of this is that key owners access to the closed unit is possible at any time.

Aufgabe der vorliegenden Erfindung ist es, ein Schließzylinder anzugeben, bei welchem der Besitz eines mit einem Schließzylinder zusammenwirkenden Schlüssels nur eine notwendige, aber keine hinreichende Bedingung für die Ausführung des Schließvorganges an diesem Schließzylinder ist.Object of the present invention is to provide a lock cylinder, in which the possession of a cooperating with a lock cylinder key is only a necessary, but not sufficient condition for the execution of the closing operation of this lock cylinder.

Die Aufgabe wird erfindungsgemäß bei einem Schließzylinder der Eingangs genannten Art dadurch gelöst, dass die Drehung des Zylinderkerns elektromechanisch unabhängig von dem zum Schließzylinder passenden Schlüssel blockierbar ist und die elektromechanische Blockierung durch einen externen Schaltvorgang auslösbar ist.The object is achieved according to the invention in a lock cylinder of the type mentioned by the fact that the rotation of the cylinder core is electromechanically independent of the lock cylinder suitable key is blocked and the electromechanical lock can be triggered by an external switching operation.

Die elektromechanische Blockierung kann ein durch ein Elektromagneten bewegter Magnetanker sein, der die Trennebene zwischen dem Zylindergehäuse und dem Zylinderkern überbrückt.The electromechanical blocking may be an electromagnet moved by an electromagnet, which bridges the parting plane between the cylinder housing and the cylinder core.

Der Magnetanker kann beispielsweise bolzenförmig sein und innerhalb einer Bohrung von dem Elektromagneten bewegt werden.The armature may, for example, be bolt-shaped and moved within a bore of the electromagnet.

Bei diesem Ausführungsbeispiel wird durch den externen Schaltvorgang der Stromfluss in dem Elektromagneten geschaltet. Dadurch verändert der Magnetanker seine Lage in der Bohrung, wobei er entweder die Trennebene zwischen Zylinderkern und Zylindergehäuse überbrückt und damit den Schließvorgang blockiert oder diese freigibt, so dass mit einem passenden Schlüssel der Schließzylinder betätigt werden kann.
Unter einem externen Schaltvorgang soll hier verstanden werden, dass dieser außerhalb des, also örtlich getrennt vom, Schließzylinder(s) ausgelöst wird.In this embodiment, the external switching operation switches the current flow in the electromagnet. As a result, the magnet armature changes its position in the bore, wherein it bridges either the parting plane between the cylinder core and cylinder housing and thus blocks the closing process or releases it, so that the lock cylinder can be actuated with a suitable key.
An external switching operation is to be understood here as being triggered outside of, ie locally separated from, the lock cylinder (s).

Dieser Schalter kann beispielsweise gegen Unbefugte gesichert sein oder so verborgen sein, dass er für Unbefugte nicht ohne Weiteres entdeckt werden kann.This switch can for example be secured against unauthorized persons or hidden so that it can not be detected by unauthorized persons without further notice.

Der Schaltvorgang kann aber auch mittels Funk ausgelöst werden. Dies kann vorteilhaft sein, um eine Vielzahl an abschließbaren Einheiten zu bestimmten Zeiten für Schließvorgänge generell zu sperren.The switching process can also be triggered by radio. This may be advantageous for generally locking a plurality of lockable units at certain times for closing operations.

Für die Ausführung der Erfindung ist das Zylindergehäuse mit einer radialen Bohrung versehen, die in eine Ausnehmung im Umfang des Zylinderkernes übergeht. Am Zylindergehäuse ist ein Elektromagnet befestigt, dessen Anker durch die Bohrung im Zylindergehäuse bis in die Ausnehmung am Zylinderkern reicht.For the embodiment of the invention, the cylinder housing is provided with a radial bore, which merges into a recess in the circumference of the cylinder core. On the cylinder housing, an electromagnet is mounted, the anchor extends through the bore in the cylinder housing into the recess on the cylinder core.

Diese Ausführung eignet sich besonders für die Nachrüstung von herkömmlichen Schließzylindern, also auch solchen, die sich bereits irgendwo im Einsatz befinden, also eingebaut sind.This version is particularly suitable for retrofitting conventional locking cylinders, including those that are already in use somewhere, so are installed.

Besonders vorteilhaft ist die erfindungsgemäße Lösung für Einfachzylinder, deren Zylindergehäuse frei in das Innere der abschließbaren Einheit hineinragt, beispielsweise dem Inneren eines Automaten.The solution according to the invention for single cylinders whose cylinder housing projects freely into the interior of the lockable unit, for example the interior of a machine, is particularly advantageous.

Hierzu werden das Zylindergehäuse und entsprechend der Zylinderkern mit einer nachträglichen Bohrung versehen und der Elektromagnet wird, beispielsweise mit einem ihn umgebenden Gehäuse, auf dem Zylindergehäuse befestigt, wobei der Elektromagnet sich so über der Bohrung befindet, dass der Magnetanker sich in der Bohrung bis in die Ausnehmung im Zylinderkern bewegen kann. Der Elektromagnet oder ein ihn umgebendes Gehäuse kann beispielsweise auf das Zylindergehäuse aufgeschraubt werden. Die Stromversorgung für den Elektromagneten kann von außerhalb herangeführt sein.For this purpose, the cylinder housing and corresponding to the cylinder core are provided with a subsequent bore and the electromagnet is, for example, with a surrounding housing, mounted on the cylinder housing, wherein the solenoid is located above the bore, that the armature is in the hole to the Recess in the cylinder core can move. The electromagnet or a housing surrounding it can for example be screwed onto the cylinder housing. The power supply for the electromagnet can be brought from outside.

In den Zeichnungen ist ein Ausführungsbeispiel für den Schließzylinder dargestellt, und zwar in der Figur 1 in einer Schnittdarstellung und in Figur 2 perspektivisch.In the drawings, an embodiment of the lock cylinder is shown, in the FIG. 1 in a sectional view and in FIG. 2 perspective.

Im Einzelnen sind das Zylindergehäuse mit 1, der Zylinderkern mit 2, der Elektromagnet mit 3, dessen Magnetanker mit 4, die Bohrung im Zylinderkern mit 5 und das den Elektromagneten aufnehmende Gehäuse mit 6 bezeichnet. Dieses Gehäuse 6 ist auf das Zylindergehäuse aufgesetzt und mit diesem durch eine Schraube 7 verbunden.
Nicht dargestellt sind die elektrische Anschlussmöglichkeit für den Elektromagneten bzw. der hierzu gehörende externe Schalter.Specifically, the cylinder housing with 1, the cylinder core with 2, the solenoid with 3, the armature with 4, the hole in the cylinder core with 5 and the electromagnet receiving housing 6. This housing 6 is placed on the cylinder housing and connected thereto by a screw 7.
