SELF-LOCKING LOCK

摘要

The invention relates to a self-locking lock with a bolt, a lock swing catch andan auxiliary swing catch, in which the bolt and lock swing catch move outwardly to a locking position in spring-loaded manner and with the door closed, and are there lockable by a slide plate whilst the auxiliary swing catch presses on a lock ing plate. With the door open, the bolt is held back in a housing of the lock and is ar rested by the auxiliary swing catch by means of the slide plate. In order to provide a lock secure against manipulation and reliable in operation, where an uncontrollab le extension of the bolt is particularly effective prevented even in intermedia te states of the opening and closing process, on opening the bolt leads compared with the lock swing catch and is arrested completely retracted in the housing of the lockwhile the lock swing catch is provided with a wideni ng, for instance, a pivotable, spring-loaded swing catch part. As a result, the lock swing catch engages fo r a longer time on the locking plate and lags behind the auxiliary swing catch, so that the slide plate and bolt are arrested until the auxiliary swing catch arrest s the slide plate and bolt. The lock swing catch widening has no effect on closing.
