In an access control device including a lock () with a locking element, an actuating element () for the locking element, an electronic key (), an electrical circuit including a receiver unit for receiving key identification data and an evaluation circuit for determining access authorization based on the received identification data, the evaluation circuit cooperates with the actuating element () and/or the locking element for selectively locking or unlocking the lock (). The electronic key () comprises means for generating a capacitive near field via which the identification data is emitted. Furthermore, a device for coupling the capacitive near field to the person () carrying the key () is provided, wherein the receiver unit of the lock () comprises at least one capacitive coupling surface such that an alternating current circuit closes at a contact of the lock (), or an approach of the lock (), by said person () and an electric flux is created across the lock (), which can be detected by the receiver unit.

Access control device

In an access control device including a lock with a locking element, an actuating element for the locking element, an electronic key, a receiver unit for receiving key identification data and an evaluation circuit for determining access authorization based on the received identification data, the evaluation circuit cooperates with the actuating element and/or the locking element for selectively locking or unlocking the lock. The electronic key includes means for generating a capacitive near field via which the identification data is emitted. Furthermore, a device for coupling the capacitive near field to the person carrying the key is provided. The receiver unit is designed as a device separate from the lock and comprises at least one capacitive coupling surface such that, at a contact of the capacitive coupling surface or an approach of the capacitive coupling surface by said person, an alternating current circuit is closed and an electric flux is created across the receiver unit, which can be detected by the receiver unit.

Apparatus for access control, and read/write device

In an apparatus, for example key () or locking cylinder (), for actuating a locking element (), having a converter () for converting mechanical into electrical energy, comprising a magnetic circuit () and an induction coil () through which the magnetic flux from the magnetic circuit passes, wherein the magnetic circuit () or the induction coil () is in the form of a movable component and the respective other part is in the form of a fixed component, the movable component is held by a leaf spring () and is arranged such that it can be deflected so as to carry out oscillating movements in only one plane.
