Abstract (en)
An actuating device with a nut (17) and a reversible screw (3) is connected by a coupling (12, 13) to a sliding door, the screw (3) itself being connected to a motor. A carriage (11) which moves along the screw comprises a lock (16, 22, 28, 24) for automatically locking this carriage when the nut (17) reaches one end of its travel and for unlocking it automatically when the screw starts to move in the opposite direction. <??>The lock (16, 22, 28, 24) moves with respect to the nut and is pushed towards a locking position by a coil spring (29) working in the winding mode. A manual unlocking means comprises a plate (37) which moves about an axis (40) in order to align the locking peg (22) and its roller (28) with a slide (23) against the action of the spring (29), this unlocking being possible even when the screw applies force in the direction of closure for safety reasons, the unlocking then only being validated when the screw is released. <??>Application to the door of a public transport vehicle. <IMAGE>
