ABSTRACT:
A drive-rod lock having drive-rods which can be displaced by turning the door handle or the like, and a nut associated with the door handle, which nut, held in its basic central position, can be swung out of said position against spring action in the opposite direction, the lock case bearing a cuff rail which continues beyond the lock case into freely extending cuff rail sections (1') behind which there are guided the drive-rods (48) which so control additional locking members, for instance swivel bolts arranged in the region of the cuff rail sections (1'). These locking members can enter into mating locking parts on the frame side, both as a result of the turning of the door handle and of the releasing of at least one force accumulator (55) acting on the drive-rods, the releasing of the force accumulator (55) being effected by means of a release (63) actuated, upon the closing of the door, by the frame or the like, the release (63) and/or the force accumulator (55) being arranged behind the freely extending cuff rail sections (1 '). In order to make the release possible also by a movement perpendicular to the cuff rail plane in the direction towards the strike plate (88), the release (63) is actuatable in a direction perpendicular to the front side of the cuff rail.
