Abstract: A reversible-screw- (3) and-nut (14) actuating device is connected by a coupling (12, 13) to a sliding door, the screw (3) itself being connected to a motor. A carriage (11) which can move along the screw comprises a lock (16, 22, 28, 24) for locking this carriage automatically when the nut (14) reaches one end of its travel and for unlocking it automatically when the screw is moved in the opposite direction.The lock (16, 22, 28, 24) can move with respect to the nut and is stressed toward a locking position by a helical spring (29) working in the direction of its winding. A manual unlocking means comprises a plate (37) which can move about an axis (40) so as to align the locking finger (22) and its roller (28) with a slide channel (23) counter to the spring (29), this unlocking being possible even when the screw forces in the direction of closing for safety reasons, the unlocking then being validated only when the screw is released.Application to a door of a public transport vehicle.See FIG. 3.
