ELECTROMECHANICAL DOOR LOCK

摘要

1991-08-30 GB 1287 AB The invention relates to an electromechanical door lock, comprising a lock body (1), which includes a dead bolt (5) movable between from the lock body protruding locking position and within the lock body withdrawn releasing position by electromechanical force transmission means, dead-locking means (6) for dead-locking the dead bolt and an operating axis provided with force transmission means for moving the dead bolt and the dead-locking means also manually for instance through key operation. The lock body (1) includes coupling means (22;23) having a first position, in which they are arranged to provide force transmission connection from both said key operable force transmission means and said electromechanical force transmission means to the dead bolt (5). The coupling means (22;23) are movable by means of said key operable force transmission means into a second position, in which the force transmission connection from said electromechanical force transmission means to the dead bolt (5) is disconnected so that the dead bolt (5) is movable only through said key operable force transmission means.
