The lock, having bolts at three or more different points including a spring bolt (3), incorporates an actuator (5) mounted coaxially with the follower (1), turned by it in one direction of rotation and staying in that position when the follower is returned to its initial position by a spring (2). The actuator forms part of a kinematic chain to operate the locking bars (11, 12) for the top and bottom bolts, the chain comprising a toothed end (6) on the actuator that engages with a pinion (7) interacting with a rocker (8). |
