ABSTRACT:
A multi-point locking system (10) has a lock case (11) with a door front edge (20), a latch (65), a blocking bolt (80) and two longitudinally movable push rods (30, 31) connected to one another by a connecting element (40) with locking elements such as eccentrically mounted roller pins (33) engaging in striking plates (34). The connecting element (40) has an engagement recess (46), is arrestable by a spring-loaded engaging element (52) against a compression spring (48) in a pretensioned opening position, and is releasable from this arrested position by direct operation of the locking elements (33) in the longitudinal direction of the door front edge. The striking plates (34) in the entry area (36) of the locking elements (33) have inclined stop surfaces (37) exerting a force (F) on the roller pins (33) in the closing direction (Y). The slidingly guided bolt (80) blocks the locking system (10) indirectly via a flexibly mounted rocker (91) using a closing element (81), for example a locking cylinder.
