Elektromechanische Schlossanordnung

摘要

An electromechanical lock arrangement includes a lock body (1), which is provided with a cylinder lock mechanism (3) having a key channel (17) and a turnable lock cylinder (16) moving a dead bolt (2) between protruding locking and withdrawn releasing positions. An electrically operable latch means (7) for controlling the operation of the dead bolt (2) and a logic unit (8) for controlling said electrically operable latch means (7) is provided. A key unit (4) has a mechanical key member (4a) for operating the cylinder lock mechanism (3) as well as means for supplying electrical power and means for sending a coded electrical signal to said logic unit (8). At the reception of a correct code, the logic unit (8) is arranged to switch current to said electrically operable latch means (7) so that it allows the dead bolt (2) to be moved from its protruding locking position. The supplying of a code and electrical power is accomplished through a conductor (14) in said mechanical key member (4a) and by making use of a first electrically conductive coupling element (18) turnable with the lock cylinder (16) and a second electrically conductive coupling element (19) stationarily installed in the lock body (1).
