Die Erfindung betrifft eine elektromagnetische Verriegelung für ein Zylinderschloß, bei dem im Zylindergehäuse ein Elektromagnet angeordnet ist, dessen beweglicher Anker in Wirkverbindung mit einem Sperrstift steht, der in Eingriff mit dem Zylinderkern bringbar ist, so daß in dieser Stellung des Sperrstiftes eine Drehung des Zylinderkernes und damit ein Schließvorgang unmöglich ist.The invention relates to an electromagnetic locking device for a cylinder lock, in which an electromagnet is arranged in the cylinder housing, the movable armature of which is operatively connected to a locking pin which can be brought into engagement with the cylinder core, so that in this position of the locking pin, rotation of the cylinder core and thus a locking process is impossible.
Elektromagnetische Verriegelungen dieser Art sind bekannt, wobei als ein Beispiel die DE-39 41 068 C2 bzw. die EP 0281 501 genannt seien.Electromagnetic locks of this type are known, with DE-39 41 068 C2 and EP 0281 501 being mentioned as an example.
Bei vielen Lösungen ist es nachteilig, daß die Blockade des Schließvorganges durch ständige Bestromung des Elektromagneten erreicht wird. Dies bedeutet einen relativ hohen Stromverbrauch, der sich natürlich dann besonders negativ bemerkbar macht, wenn die Energie einer Batterie entnommen wird.The disadvantage of many solutions is that the locking process is blocked by constantly supplying current to the electromagnet. This means a relatively high power consumption, which is of course particularly noticeable when the energy is taken from a battery.
Der Erfindung liegt daher die Aufgabe zugrunde, eine elektromagnetische Verriegelung der im Oberbegriff des Anspruchs 1 genannten Art so auszubilden, daß einerseits die Sicherheit gegen unerlaubte Betätigung des Schließzylinders erhöht und gleichzeitig der Energieaufwand gesenkt wird.The invention is therefore based on the object of designing an electromagnetic locking device of the type mentioned in the preamble of claim 1 in such a way that, on the one hand, the security against unauthorized operation of the locking cylinder is increased and, at the same time, the energy consumption is reduced.
Gelöst wird diese Aufgabe erfindunggemäß 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.Preferred embodiments result from the subclaims.
Der wesentliche Gedanke der Erfindung liegt darin, daß der Elektromagnet nicht ständig bestromt ist, sondern die eigentliche Blockade des Schließzylinders im unbestromten Zustand des Elektromagneten erfolgt und somit die Energiezufuhr nur noch für die Freigabe - also für einen relativ kurzen Zeitraum - notwendig ist.The essential idea of the invention is that the electromagnet is not constantly energized, but the actual blocking of the locking cylinder takes place when the electromagnet is not energized and thus the energy supply is only necessary for the release - i.e. for a relatively short period of time.
Die Erfindung soll nun an Hand der Figuren erläutert werden, wobei in den Figuren 1 bis 3 lediglich der Elektromagnet und nicht der Schließzylinder insgesamt dargestellt ist.The invention will now be explained with reference to the figures, whereby in figures 1 to 3 only the electromagnet and not the locking cylinder as a whole is shown.
Die Figur 1 zeigt zunächst den Elektromagneten in seiner Ruhestellung, d.h., der Blockadestellung - bezogen auf den Schließzylinder.Figure 1 first shows the electromagnet in its rest position, i.e. the blocking position - in relation to the locking cylinder.
In einem Außenmantel 2 ist eine Magnetspule 7 angeordnet, in der sich der Anker S befindet. Dieser Anker 6 steht unter Federdruck durch die Feder 8 und wird dadurch ständig nach oben, also aus der Spule heraus gedrückt. Mit dem Anker 6 ist ein Verriegelungsring 3 fest verbunden. Dieser Verriegelungsring 3 umgibt koaxial eine Kugelführung 4. Zwischen der Kugelführung 4 und dem Verriegelungsring 3 sind bei diesem Ausführungsbeispiel Kugeln 5 vorgesehen, von denen hier im Schnitt zwei zu sehen sind. Mit der Kugelführung 4 ist der Sperrstift 1 verbunden, der mit einem nicht dargestellten Zylinderkern zusammenwirkt d.h. mit ihm in Eingriff bringbar ist.A magnetic coil 7 is arranged in an outer casing 2, in which the armature S is located. This armature 6 is under spring pressure by the spring 8 and is thereby constantly pushed upwards, i.e. out of the coil. A locking ring 3 is firmly connected to the armature 6. This locking ring 3 coaxially surrounds a ball guide 4. In this embodiment, balls 5 are provided between the ball guide 4 and the locking ring 3, two of which can be seen here in the section. The locking pin 1 is connected to the ball guide 4, which interacts with a cylinder core (not shown), i.e. can be brought into engagement with it.
Pat/M/Pt/P1433Pat/M/Pt/P1433
Wie oben angegeben, ist in der Figur 1 die Blockadestellung gezeigt. In dieser Stellung steht also der Sperrstift 1 in Eingriff mit dem Zylinderkern und blockiert so einen Schließvorgang.As stated above, the blocking position is shown in Figure 1. In this position, the locking pin 1 is in engagement with the cylinder core and thus blocks a closing process.
Der federbelastete Sperrstift 1 kann nicht außer Eingriff mit dem Zylinderkern gebracht werden, weil die Kugeln 5 nicht radial nach außen gedrängt werden können.The spring-loaded locking pin 1 cannot be disengaged from the cylinder core because the balls 5 cannot be pushed radially outwards.
Wird nun aber dem Elektromagneten Strom zugeführt, so zieht die Magnetspule 7 den Anker 6 nach unten und damit auch den Verriegelungsring 3. Hierdurch wird aber - wie die Figur 2 zeigt - die ringförmige Ausnehmung im Verriegelungsring in eine Position gebracht, bei der eine radiale Bewegung der Kugeln 5 möglich ist.However, if current is now supplied to the electromagnet, the magnetic coil 7 pulls the armature 6 downwards and thus also the locking ring 3. As a result, however - as Figure 2 shows - the annular recess in the locking ring is brought into a position in which a radial movement of the balls 5 is possible.
Wie die Figur 3 zeigt, kann nunmehr der Sperrstift 1 nach unten bewegt werden, wobei hierdurch die Kugeln sich radial verlagern, und diese Bewegung des Sperrstiftes führt zu einer Freigabe des Zylinderkernes. Ein Schließvorgang kann somit ausgeführt werden.As Figure 3 shows, the locking pin 1 can now be moved downwards, whereby the balls are displaced radially, and this movement of the locking pin leads to a release of the cylinder core. A closing process can thus be carried out.
