Lock with spring-loaded lock nut

Abstract

A multi-point locking system (3) is proposed, comprising a lock housing (32) in which a multi-point locking bar (33, 34) for locking the lock and a bolt slide (37) for unlocking an active leaf lock are movably mounted, further comprising an electric motor (4) arranged in the lock housing (32) and a rotatable lock follower (31) for motorized and / or manual unlocking of the multi-point locking system (3). In the locked position, the lock follower (31) is in its rest position and is returned to this position by means of two return springs (51, 52). To make the motor drive of the lock (3) as compact and reliable as possible, it is proposed that during motorized unlocking, the motor (4) actuates only one of the two return springs (51 or 52), and that during manual unlocking, the lock follower actuates both return springs (51 and 52).
