  • Patent number: 5058938
    Abstract: A drive-rod lock has drive rods which can be displaced by turning a door handle or the like, and a nut associated with the door handle. The nut, held in its basic central position, can be swung out of that position against spring action in the opposite direction. The lock case bears a cuff rail which continues beyond the lock case into freely extending cuff-rail sections behind which there are guided drive rods. The drive rods control additional lock members, for instance swivel bolts, arranged in the region of the cuff-rail sections. These locking members operate both by the turning of the door handle and as a result of release of at least one force accumulator acting on the drive rods. Operation is obtained by means of a release which is actuated upon the closing of the door by the frame, or the like, and for a favorable positioning of the release even with a small depth of the drive-rod lock.
