Abstract

The lock cylinder has a housing (4) containing a rotatable core (1). There is an electronic evaluation unit (3) in the core for the coding of a key plus a device (5) to transmit the coding from the key to the unit. There is a power supply in the key or in the lock housing or core as well as an electromechanical lock mechanism working between the core and the housing. The lock mechanism has a bar (8) moving over the plane separating the core from the housing and a magnetic armature (17) with coil (18) which releases or blocks it. The bar can be pressed against a spring (16) in a recess in the housing.

Description

Die Erfindung betrifft einen Schließzylinder für ein Schloß, bestehend aus einem Schließzylindergehäuse und einem in diesem drehbar gelagerten Zylinderkern.The invention relates to a lock cylinder for a lock, consisting of a Lock cylinder housing and a cylinder core rotatably mounted in it.

Bekannte Schließzylinder mit elektronischer Codeerkennung, -Auswertung und Verriegelung arbeiten mit Anordnungen der Elektronik und der elektromechanischen Bauelemente im Zylindergehäuse. Dies erscheint vorerst vorteilhaft, weil Zylindergehäuse mehr Bauraum bieten als ein Zylinderkern. Ferner bieten sie als üblicherweise ortsfest in Türen montierte Baugruppen die Möglichkeit der Verdrahtung mit elektrischen Energieversorgungen und elektronischen Steuerungen zur Auswertung des elektrischen Codes von Schlüsseln.Known locking cylinders with electronic code recognition, evaluation and Interlocking work with arrangements of electronics and electromechanical Components in the cylinder housing. This seems advantageous for the time being because Cylinder housings offer more installation space than a cylinder core. They also offer as Assemblies usually installed in a fixed position in doors with the possibility of wiring electrical power supplies and electronic controls for evaluating the electrical codes of keys.

Nachteil dieser Anordnungen ist die Tatsache, daß bei Verwendung verschiedener Schließzylindertypen verschiedene Gehäusebauformen mit beliebig vielen unterschiedlichen Verhältnissen hinsichtlich des Bauraumes für die Unterbringung von Elektronik und Elektromechanik notwendig sind. Diese Vielfalt verhindert generell die Möglichkeit, elektronische Codierungssysteme unabhängig von der Zylindertype bzw. Bauform auf breiter Basis einzusetzen. Realisierte Systeme von Elektronikzylindern arbeiten mit Elektronik als Zusatzcodierung und Elektromechanik als Zusatzverriegelung. Die hier beschriebene Ausführung geht davon aus, daß die Codierung von Schlüsseln und Decodierung durch den Schließzylinder weitgehend elektronisch erfolgt.The disadvantage of these arrangements is the fact that when using different Lock cylinder types different housing designs with any number different conditions with regard to the installation space for the accommodation of Electronics and electromechanics are necessary. This diversity generally prevents that Possibility of electronic coding systems regardless of the cylinder type or Use the design on a broad basis. Realized systems of electronic cylinders work with electronics as additional coding and electromechanics as additional locking. The embodiment described here assumes that the coding of keys and decoding is largely done electronically by the lock cylinder.

Die vorliegende Erfindung löst dieses weitgehend auf der Basis eines mit elektronischer Codierung arbeitenden Prinzips und ist gekennzeichnet durch eine im Zylinderkern eingelagerten Auswerteelektronik für eine elektronische oder elektronisch les- oder auswertbare Codierung eines Schlüssels, eine Einrichtung zum Übertragen der Codierung vom Schlüssel auf die Auswerteelektronik, sowie durch eine Energieerzeugungseinheit im Schlüssel und/oder im Schließzylindergehäuse oder Zylinderkern und eine elektro-mechanische Sperreinrichtung, die zwischen Zylinderkern und Schließzylindergehäuse wirkt. The present invention solves this largely on the basis of an electronic Coding principle and is characterized by a in the cylinder core embedded evaluation electronics for an electronic or electronic read or evaluable coding of a key, a device for transmitting the Coding from the key to the evaluation electronics, as well as by a Power generation unit in the key and / or in the lock cylinder housing or Cylinder core and an electro-mechanical locking device between the cylinder core and lock cylinder housing acts.  

Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen. Kernmerkmale der Erfindung sind also:Advantageous refinements result from the subclaims. The core features of the invention are therefore:

Unterbringung der Zylinderelektronik für die Kommunikation mit dem Schlüssel im Zylinderkern (Rotor).Housing the cylinder electronics for communication with the key in the Cylinder core (rotor).

Unterbringung der elektromechanischen Verriegelung im Zylinderkern.Housing the electromechanical lock in the cylinder core.

Nutzung des Zylindergehäuses lediglich als Stator und Gegenlager für die Zylinderverriegelung.Use of the cylinder housing only as a stator and counter bearing for the Cylinder lock.

Versorgung mit elektrischer Energie vorzugsweise vom Schlüssel aus.Supply of electrical energy preferably from the key.

Versorgung mit elektrischer Energie wahlweise oder unterstützend vom Zylinderkern aus.Supply of electrical energy either selectively or as a support from the cylinder core.

Versorgung mit elektrischer Energie wahlweise oder unterstützend vom Zylindergehäuse aus.Electrical energy supply either selectively or as a support from the cylinder housing out.

Versorgung mit elektrischer Energie wahlweise oder unterstützend vom Zylinderkern und vom Zylindergehäuse aus.Supply of electrical energy optionally or as a support from the cylinder core and from the cylinder housing.

Die elektronische Codeerkennung des Schlüssels/Codeträgers ist vollständig im Zylinderkern untergebracht.The electronic code recognition of the key / code carrier is completely in the Cylinder core housed.

Die Erfindung soll an Hand eines Ausführungsbeispieles erläutert werden, wobei in der Figur ein Längsschnitt durch einen Teil des Schließzylinders und Zylinderkernes dargestellt ist.The invention will be explained using an exemplary embodiment, wherein in the Figure shows a longitudinal section through part of the locking cylinder and cylinder core is shown.

Im vorliegenden Ausführungsbeispiel befindet sich im Zylinderkern (1) ein Schlüsselkanal (2), mindestens eine Tasche mit eingelagerter Elektronik (3), eine elektrische Verbindung zur Verbindung mit dem Schlüssel (6) für die Übertragung von elektrischer Energie und der Codierung, hier am Beispiel mit Kontakten (5) gezeigt, eine elektromechanische Verriegelungsanordnung (7) für die Steuerung der Zylinderverriegelung, elektromagnetisch oder Gedächtnismetallauf Piezzobasis, eine Sperrleiste (8) zur Verriegelung von Zylinderkern und -gehäuse. In the present exemplary embodiment there is a key channel ( 2 ) in the cylinder core ( 1 ), at least one pocket with embedded electronics ( 3 ), an electrical connection for connection with the key ( 6 ) for the transmission of electrical energy and the coding, here using the example shown with contacts ( 5 ), an electromechanical locking arrangement ( 7 ) for controlling the cylinder locking, electromagnetic or piezo-based memory metal, a locking bar ( 8 ) for locking the cylinder core and housing.

Beim Einstecken des Schlüssels in den Schlüsselkanal wird durch elektrische Koppelung durch Kontakte oder berührungslos, z. B. induktiv, eine elektrische Verbindung zwischen Schlüssel, Zylinderkern, der Energieversorgung, Schlüsselcode und Auswerteelektronik hergestellt. Nach Auswertung der Codierung und Entscheidung über die Schließberechtigung wird durch Aktivieren oder Deaktivieren des elektromechanischen Freigabemechanismus der Schließvorgang ermöglicht oder blockiert.When the key is inserted into the key channel, it is electrically coupled through contacts or contactless, e.g. B. inductive, an electrical connection between Keys, cylinder core, power supply, key code and evaluation electronics produced. After evaluating the coding and deciding on the Locking authorization is obtained by activating or deactivating the electromechanical Release mechanism that enables or blocks the closing process.

Im gezeigten Beispiel blockiert eine Sperrleiste den Zylinderkern im Zylindergehäuse (14). Beim Schließvorgang (Drehen des Zylinderkernes) wird die Sperrleiste über die Schrägen (15) gegen die Kraft der Feder (16) in den Zylinderkern gedrückt. Im Falle der Nichtfreigabe blockiert der Magnetanker (17) - hier zweiteilig - das Eintauchen der Sperrleiste in den Zylinderkern. Im Falle der Freigabe des Schließvorganges geben die in den Elektromagneten (18) eingetauchten Magnetanker die Hubbewegung der Sperrleiste und damit den Schließvorgang frei. Die elektrischen Verbindungen zwischen Elektronik, Zylinderkern, Sperrmechanismus und Kontakten sind nicht dargestellt.In the example shown, a locking bar blocks the cylinder core in the cylinder housing ( 14 ). During the closing process (turning the cylinder core), the locking bar is pressed over the bevels ( 15 ) against the force of the spring ( 16 ) in the cylinder core. In the event of non-release, the magnetic armature ( 17 ) - here in two parts - blocks the immersion of the locking bar in the cylinder core. If the closing process is released, the magnetic armatures immersed in the electromagnet ( 18 ) release the lifting movement of the locking bar and thus the closing process. The electrical connections between electronics, cylinder core, locking mechanism and contacts are not shown.
