The invention relates to an unlocking device for actuating a control device which is in locked condition in order to release it. Said unlocking device comprises an actuating magnet which, guided in a coil base and/or in housing elements (28) of the actuating magnet, has an actuating element that can be displaced and that releases, in an actuation position, an unlocking path for a control unit having a locking element (30). Said locking element, when unlocked by means of the actuating element via the control device, releases the trajectory for the control device to be actuated. The invention is characterized in that the locking device (30) is guided in the housing element (28) of the actuating magnet and prevents the control device from being unintentionally locked again by being maintaining it in the unlocked position on the same by means of a blocking part (48), the unlocked position corresponding to a release of the control device.
An unlocking device for actuating a control part (10) which is in the locked state in order to release it, with an actuating magnet (12) which, guided in a coil base (14) and/or in housing parts of the actuating magnet (12), has an actuating element (16) which can be moved and which in the actuating position clears an unlocking path (22) for a control unit (24) which has a locking part (30) which, unlocked by means of the actuating element (16) via the control unit (24), clears the path (32) of movement for the control part (10) which is to be actuated, characterized in that the locking part (30) is guided in the housing part (28) of the actuating magnet (12), and held on the latter by means of a blocking part (48) in the unlocked position which corresponds to the release of the control part (10), prevents unwanted re-locking of the control part (10).
