Lock with an electromechanical coupling device

A lock, in particular a door lock, comprising an electromechanical coupling device which effects an operative connection with a driven member, when an authentication code is recognized, with the driven member in constant operative connection with an operating mechanism, said drive member and said driven member of the coupling device each being spring-loaded into a rest position and configured for coupling via a locking mechanism which is switchable by an electromechanical transducer between a disengaged position and an engaged position, said locking mechanism comprising

• an actuator releasably latched with the drive member and moveable in a same direction as the drive member, when the locking mechanism is in the disengaged position, and blocked in its rest position by the electromechanical transducer in the engaged position, with the latching action being automatically released upon movement of the drive member, and
• at least one locking member which is movable into and out of engagement with the drive member approximately at a right angle to a plane of movement of the drive member,
• said actuator having a recess disposed opposite the locking member in the rest position, and said driven member having a recess which is disposed opposite the locking member,
• wherein in the disengaged position, the driven member in its rest position urges the locking member into the recess of the actuator entrained by the drive member upon movement of the drive member, and in the engaged position, the actuator blocked in its rest position urges the locking member into the recess of the driven member and thereby entrains the driven member, upon movement of the drive member, and wherein in the disengaged position, the driven member in its rest position urges the locking member into the recess of the actuator entrained by the drive member upon movement of the drive member, and in the engaged position, the actuator blocked in its rest position urges the locking member into the recess of the driven member and thereby entrains the driven member, upon movement of the drive member, wherein the releasable latching between the actuator and the drive member includes an engagement part connected with one of the actuator and drive member and engaging in the recess of the other one of actuator and drive member under an elastic bias.
