Drive rod closure mechanism has bolt, main and extra locks, tie bolt, retention element, striking plate and stop

摘要

The driving rod closure mechanism consists of a bolt (5) from a main lock (3) spaced apart from an extra lock (9,10) with a bolt-like retention element (11) controlled by the drive rod. A blunt-ended tie-bolt (29) is positioned between the main lock bolt and the retention element and is spring-loaded towards bolt-entry openings in a striking plate. The tie bolt is held in a pulled-back position by a blocking shoulder exerting pressure on a stop (26). A slanting control is next to the drive rod (8).
