A device for actuating elevator doors, comprising means (2) for moving the car door (3) and at least one device (5) for coupling between the car door (3) and the floor doors (6). The movement means (2) comprise at least one first flexible element (7) for motion transmission which extends between first guiding wheels (8a, 8b), of which at least one is connected to a first motor, and the coupling device (5) is actuatable by means of a second flexible element (10) for motion transmission which extends between second guiding wheels (11a, 11b), of which at least one is connected to a second motor; means (12) being also provided for interconnection between the first and second flexible elements (7, 10) which functionally connect the first and second flexible elements (7, 10) to the coupling device (5) and are adapted to transmit mutually cooperating synergistically forces, selectively to the coupling device (5) or to the car door (3).
