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.
A multi-point locking system (10) for locking doors (T) having a lock case (11), a door front edge (20) attached thereto, a spring-loaded latch (65) passing through said door front edge (20), a locking bolt (80) passing through said door front edge (20) and operable via a closing element (81) and at least two longitudinally movable push rods (30, 31) connected to one another by a connecting element (40) with locking elements (33) engaging in corresponding recesses, where the push rods are movable into an opening position against a resetting force by a handle mounted in a pivotable nut and are arrestable in this pretensioned position, wherein the connecting element (40) between the push rods (30, 31) is loaded in a closing direction (Y) by a compression spring (48) and wherein the push rods (30, 31) are releasable from the arrested position by direct operation of the locking elements (33) in the longitudinal direction (L) of the door front edge (20).
A multi-point locking system (10) for locking doors (T) including a lock case (11), a door front edge (20) attached thereto, a spring-loaded latch (65) passing through the door front edge (20), a locking bolt (80) that passes through the door front edge (20) and is operable via a closing unit (81), at least two longitudinally movable push rods (30, 31) joined to one another by a connection element (40) and provided with locking elements (33) that engage in corresponding recesses (35) of striking plates (34) fixed to a door frame (R) opposite the door front edge (20), and further including a handle (61) mounted to turn with a pivotable lock nut (60) whereby the push rods (30, 31) are movable into an opening position against a resetting force and are arrestable in a pretensioned position, wherein the connection element (40) between the push rods (30, 31) is loaded by a compression spring (48) in a closing direction (Y) and wherein the push rods (30, 31) are releasable from an arrested position by direct operation of the locking elements (33) in a longitudinal direction (L) of the door front edge (20).
A locking system according to claim 25, wherein the striking plates (34) have stop surfaces (37) disposed in an entry area (36) of the locking elements (33) and inclined at an angle (.alpha.) to the longitudinal direction (L) whereby a force (F) acting parallel to the push rods (30, 31) is exerted on the locking elements (33) as the door (T) is closed.
