<p>A latch-and-bolt lock with simultaneous actuation of the bolt (10) and of the latch (9) during closure, the latch and the bolt being actuated by elastic means (20, 45) so as to protrude from the lock in order to engage in respective selvages of the jamb, characterized in that it comprises: a sensor (68) for detecting a closed position of a door whereon the lock is fitted, the sensor being movable at right angles to a faceplate (8) of the lock between an external position and an internal position relative to the lock and being retained in the internal position by abutment against the doorjamb; a slider (78) which is guided parallel to the latch; a plate (96) for blocking the bolt, which is guided transversely to the slider; a lever (84) which is articulated to the slider (78) and has a first arm (85) which is operatively associated with the sensor and a second arm (87) which is adapted to assume a position for blocking the latch when the sensor and the latch are inside the lock, a member (89) for the actuation of the plate (96) being arranged on the slider (78) and being such that when the latch, after abutment against the doorjamb, is aligned with the corresponding selvage of the doorjamb, by way of the stroke of the latch for engagement in the selvage, the slider (78) is moved into aposition in which the actuation member (89) disengages the plate (96) from the bolt (10) and engages the bolt (10) in the corresponding selvage under the thrust of the elastic means.</p> |
