Description

Die Erfindung betrifft ein Doppelzylinderschloß, dessen zwei Schließzylinder über eine axial durch die eingeführten Schlüssel verschiebbare Kupplung mit dem Schließbart in Eingriff bringbar sind, sowie mit einem in dem einen Schließzylinder angeordneten Sperrmagneten, der über eine elektronische Codierung im Schlüssel sowie eine im Schließzylinder angeordnete Antenne betätigbar ist, wobei die Schlüssel außerdem eine mechanische Codierung aufweisen, die mit Zuhaltungen im Schließzylinder zusammenwirkt.The invention relates to a double cylinder lock, the two lock cylinders can be brought into engagement with the lock bit via a coupling which can be axially displaced by the inserted key, as well as with a locking magnet arranged in the one lock cylinder, which can be actuated via electronic coding in the key and an antenna arranged in the lock cylinder is, wherein the keys also have a mechanical coding that interacts with tumblers in the lock cylinder.

Ein derartiges Doppelzylinderschloß ist aus der DE 39 41 068 C2 und aus der Praxis bekannt. Hierbei kann ein Schließvorgang im allgemeinen nur dann eingeleitet werden, wenn sowohl die mechanische wie auch die elektronische Codierung des eingeführten Schlüssels richtig sind.Such a double cylinder lock is known from DE 39 41 068 C2 and from practice. In this case, a locking process can generally only be initiated if both the mechanical and the electronic coding of the key inserted are correct.

Bei einem Ausfall der elektrischen Stromversorgung für den Sperrmagneten können sich Probleme ergeben, weil die Tür von der Innenseite her nicht ohne weiteres zu öffnen ist, d.h., die richtige mechanische Codierung reicht zum Öffnen nicht aus. Andererseits wird bei diesen bekannten Schließzylindern die mechanische Codierung auch beim äußeren Schließzylinder abgefragt. Hier sind Manipulationsversuche zur Überwindung der Zuhaltungen nicht auszuschließen.In the event of a failure of the electrical power supply for the locking magnet, problems can arise because the door cannot be easily opened from the inside, ie the correct mechanical coding is not sufficient to open it. On the other hand, in these known locking cylinders, the mechanical coding is also queried for the outer locking cylinder. Manipulation attempts to overcome the tumblers cannot be ruled out here.

Der Erfindung liegt daher die Aufgabe zugrunde, den Doppelschließzylinder der eingangs genannten Art so auszubilden, daß von außen nur mit Hilfe der elektronischen Codierung ein Schließvorgang eingeleitet werden kann, während von innen das Schloß sowohl mit einem eine elekronische Codierung aufweisenden Schlüssel als auch mit einen mechanisch codierten Schlüssel geöffnet werden kann.The invention is therefore based on the object of designing the double locking cylinder of the type mentioned in such a way that a locking operation can only be initiated from the outside with the aid of electronic coding, while from the inside the lock can be operated both with an electronic coding key and with a mechanical key coded key can be opened.

Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen im Anspruch 1.This object is achieved according to the invention with the features in claim 1.

Vorzugsweise Ausgestaltungen ergeben sich aus den Unteransprüchen.Refinements preferably result from the subclaims.

Der Kerngedanke der erfindungsgemäßen Lösung liegt darin, daß eine Möglichkeit geschaffen wurde, die Sperrwirkung des Elektromagneten zu überbrücken, wenn der Schließvorgang von der Innenseite der Tür ausgeführt wird.The main idea of the solution according to the invention is that a possibility has been created to bridge the blocking effect of the electromagnet if the closing operation is carried out from the inside of the door.

Die Erfindung soll nachfolgend an Hand der Zeichnungen erläutert werden.The invention will be explained below with reference to the drawings.

Dabei zeigen die Figuren 1 und 2 Teilschnitte durch das erfindungsgemäße Doppelzylinderschloß bei einem Schließvorgang von innen (Fig. 1) bzw. von Außen (Fig. 2).Figures 1 and 2 show partial sections through the double cylinder lock according to the invention during a closing process from the inside (Fig. 1) or from the outside (Fig. 2).

In der Figur 1 ist der Schlüssel 18 in den inneren Schließzylinder 11 eingeführt und hierdurch ist die Kupplung 7 zusammen mit der Hülse 4 nach links verschoben worden. Durch diese Verschiebung ist der Stift 2 aus der Nut 17 herausgedrückt und radial nach oben gehoben worden.In FIG. 1, the key 18 is inserted into the inner lock cylinder 11, and as a result the clutch 7 together with the sleeve 4 has been moved to the left. This displacement has pushed the pin 2 out of the groove 17 and raised it radially upward.

Dieser Stift wirkt mit einem Sperrelement 3 - in diesem Fall einer Kugel - zusammen. Diese Kugel ist in der Hülse 4, in einer Bohrung 14, gelagert.This pin interacts with a locking element 3 - in this case a ball. This ball is mounted in the sleeve 4, in a bore 14.

Durch die radiale Verschiebung kann sie in eine ringförmige Ausnehmung 15 im Schließzylinder 11 eintreten. Diese radiale Bewegung des Stiftes 2 bewirkt eine Trennung des Kraftschlusses zwischen Hülse 4 und Kupplung 7 d.h. die Kupplung kann relativ zur Hülse verdreht werden. Da die Hülse 4 andererseits mit dem Anker 16 des Elektromagneten 6 in Eingriff steht, wird diese fixiert. Am inneren Schließzylinder 11 ist keine Antenne zum Lesen der elektronischen Codierung vorgesehen. Somit bleibt die Sperrung aufrechterhalten. Dennoch kann - wie vorher erwähnt-die Kupplung relativ zur Hülse verdreht, also der Schließvorgang ausgeführt werden.Due to the radial displacement, it can enter an annular recess 15 in the locking cylinder 11. This radial movement of the pin 2 causes a separation of the frictional connection between the sleeve 4 and the coupling 7 i.e. the coupling can be turned relative to the sleeve. Since the sleeve 4, on the other hand, engages with the armature 16 of the electromagnet 6, it is fixed. No antenna for reading the electronic coding is provided on the inner locking cylinder 11. The lock is thus maintained. Nevertheless, as previously mentioned, the coupling can be rotated relative to the sleeve, ie the closing process can be carried out.

In der Figur 2 ist dagegen der Schlüssel von der Außenseite eingeführt. Auch hierbei wird die Kupplung 7 durch den eingeführten Schlüssel verschoben und zwar in diesem Fall nach rechts.In contrast, in FIG. 2 the key is inserted from the outside. Here, too, the clutch 7 is displaced by the key inserted, in this case to the right.

Beim oder nach dem Einführen des Schlüssels wird die elektronische Codierung durch die Antenne 10 ,,gelesen". Ist die Codierung richtig, so wird der Elektromagnet 6 aktiviert und der Anker 16 gibt die Hülse 4 frei. Wie vorher erwähnt ist die Hülse 4 über den Stift 2 mit der Kupplung 7 gekoppelt, so daß - bei freigegebener Hülse - die Kupplung und damit der Schließbart 12 gedreht werden kann. Der Schließvorgang wird ausgeführt, wobei allein die Überprüfung der elektronischen Codierung erfolgte.When or after inserting the key, the electronic coding is "read" by the antenna 10. If the coding is correct, the electromagnet 6 is activated and the armature 16 releases the sleeve 4. As previously mentioned, the sleeve 4 is over the Pin 2 coupled to the coupling 7 so that - with the sleeve released - the coupling and thus the locking bit 12 can be rotated, the closing operation being carried out, the electronic coding being checked only.
