Abstract
A remote controlled door lock unit includes a motor for driving a worm gear having stop elements at its ends for abutment with a travelling nut; and having tangentially facing stop and counterstop surfaces. The axially moved nut drives the lock actuator. The motor is turned on via a time relay just to drive the nut from one to the opposite stop position.
