Abstract

The invention relates to a key for an electronically coded lock, there being arranged in the key spine a coil for inductive energy and data transmission which interacts with a reading head located in the lock. So that decoding can be carried out, that is to say a lock temporarily or permanently blocked in relation to a specific key, the key (1) is permanently connected to an electronic circuit initiating an adjustable decoding.

Description



Die Neuerung betrifft einen Schlüssel für ein elektronisch codiertes Schloß, wobei im Schlüsselrücken eine Spule für die induktive Energie- und Datenübertragung angeordnet ist, die mit einem schloßseitigen Lesekopf zusammenwirkt.The innovation relates to a key for an electronically coded lock, wherein a coil for inductive energy and data transmission is arranged in the back of the key, which co-operates with a read head on the lock side.

Bei derartigen Schlüsseln befindet sich im Schlüsselkopf ein Modul mit einem Mikroprozessor und einem Festspeicher, der die Unikat -Codierung trägt. Dieser Schlüsselcode wird mit den im Schloß gespeicherten Kennungen verglichen, und bei Übereinstimmung mit dem Schlüsselcode wird der Riegel des Schlosses für den mechanischen Schließvorgang freigegeben. Stimmt die Codierung nicht überein, so blockiert das Schloß.
Das Ablesen der Codierung erfolgt hierbei über einen schloßseitigen Lesekopf induktiv.With such keys there is a module in the key head with a microprocessor and a permanent memory, which carries the unique coding. This key code is compared with the identifiers stored in the lock, and if the key code matches, the bolt of the lock is released for the mechanical locking process. If the coding does not match, the lock blocks.
The coding is read inductively via a lock-side read head.

Der Neuerung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, um eine Decodierung vorzunehmen, d.h. ein Schloß für einen bestimmten Schlüssel vorübergehend oder ständig zu sperren, wenn dieser Schlüssel, d.h. der Schlüssel mit einer entsprechenden Codierung vorher eine Schließberechtigung hatte.The innovation is based on the task of creating a possibility for decoding, i.e. temporarily or permanently lock a lock for a particular key if that key, i.e. the key with an appropriate code previously had locking authorization.

Gelöst wird diese Aufgabe neuerungsgemäß dadurch, daß der Schlüssel ständig mit einer eine einstellbare Decodierung auflösenden Elektronikschaltung verbunden ist.According to the innovation, this object is achieved in that the key is constantly connected to an electronic circuit that resolves an adjustable decoding.

Gemäß der Ausgestaltung der Erfindung ist diese Elektronikschaltung in einem Gehäuse angeordnet, in bzw. an dem eine der Anzahl der Code-Stellen entsprechende Anzahl von Einstellschaltern vorgesehen ist, und dieses Gehäuse ist mit dem Schlüssel über eine flexible Anschlußleitung verbunden.According to the embodiment of the invention, this electronic circuit is arranged in a housing, in or on which a number of setting switches corresponding to the number of code positions is provided is, and this housing is connected to the key via a flexible connecting line.

Um ein Schloß für einen bestimmten Schlüssel zu sperren, wird die Codierung, die der zu sperrende Schlüssel aufweist, mittels der Elektronikschaltung eingestellt und nach Einführen dieses Schlüssels in das Schloß erfolgt über den Energie- und Datenaustausch der Spulen eine Löschung oder Decodierung im eingestellten Sinne, d.h. das Schloß kann später von einem Schlüssel, der diese Codierung aufweist, nicht mehr geöffnet werden, d.h. das Schloß stellt hier beim Lesevorgang keine Übereinstimmung des Schlüsselcodes mit der im Schloß gespeicherten Kennung fest, so daß das Schloß blockiert.In order to lock a lock for a specific key, the coding that the key to be locked has is set by means of the electronic circuit and after inserting this key into the lock, the coils are deleted or decoded in the set sense via the energy and data exchange of the coils, ie the lock can no longer be opened later by a key that has this coding, i.e. during the reading process, the lock does not determine that the key code matches the identifier stored in the lock, so that the lock is blocked.

In der beigefügten Figur ist der neuerungsgemäße Schlüssel dargestellt, wobei dieser aus dem elektronischen Schlüssel 1 besteht, der im Schlüsselrücken die Energie- und Datenübertragungsspule 5 aufweist. Dieser Schlüssel 1 ist ständig mit einem Gehäuse 2 verbunden, und zwar über eine flexible Anschlußleitung 4, die eine Elektronikschaltung aufnimmt. Mittels im oder am Gehäuse angeordneter Einstellschalter 3 wird die zu löschende Codierung eingestellt, und nach Einführen des Schlüssels in das Schloß gelangt ein entsprechendes Decodiersignal von der Schaltung über die flexible Anschlußleitung 4, den Schlüssel 1, die Spule 5 zum Elektroniksystem des Schlosses, wo die entsprechende Löschung der eingestellten Codierung durchgeführt werden kann, wenn eine entsprechende Bestätigung über einen gesonderten Programmschlüssel erfolgte. Damit ist das Schloß für diese eingestellte Kennung gesperrt, d.h. kann mit einem Schlüssel, der diese Codierung trägt, nicht mehr betätigt werden.In the attached figure, the new key is shown, which consists of the electronic key 1, which has the energy and data transmission coil 5 in the back of the key. This key 1 is constantly connected to a housing 2, namely via a flexible connecting line 4, which receives an electronic circuit. By means of the setting switch 3 arranged in or on the housing, the coding to be deleted is set, and after inserting the key into the lock, a corresponding decoding signal arrives from the circuit via the flexible connecting line 4, the key 1, the coil 5 to the electronic system of the lock, where the Corresponding deletion of the set coding can be carried out if a corresponding confirmation has been made using a separate program key. This locks the lock for this set identifier, i.e. can no longer be operated with a key bearing this coding.
