Compact bolt lock with motorized drive

Abstract

The invention relates to a multi-point locking system (3) for locking or unlocking a fixed leaf (14) of a double-leaf door (11), wherein the multi-point locking system (3) has a lock housing (32) in which at least one insertion slide (331, 341) for at least one multi-point locking bar (33, 34) and a locking bolt slide (37) for unlocking an active leaf lock are arranged and are movable between an unlocked position and a locked position. Furthermore, a lock follower (31) is rotatably mounted in the lock housing (32) to manually unlock the multi-point locking system (3).In order to enable the locking bolt (3) to be unlocked by motor and to achieve the most compact design possible, it is proposed that a single-armed lever (9) is rotatably mounted about a bearing pin (91) in the lock housing (32) and that an electric motor (4) with a spindle (6) and a spindle nut (61) acts on the lever (9) to move the insertion slide (331, 341) into its unlocked position by means of the lever (9) by means of a motor-driven action.
