<p>An electro-motive drive device for opening and closing a tip-up garage door, having a drive unit (35) which is to be fixedly attached at a distance from the door lintel with an electric motor and a drive cable drum (4), limit switches (44, 45) for switching off the motor in the open or closed position of the door wing and a pulling cable (3) which is guided over the cable drum (4) and a deflection roller which is fastened in the region of the door lintel, has a slide (2) which is guided in a guide rail and is connected to the door wing by means of a connecting rod. The limit switches (44, 45) are accommodated in the drive unit (35) and are actuated in the end positions by means of a switch rod (39) which is mounted so as to be longitudinally displaceable and engages in a cable groove (37) of the cable drum (4) using a pickup (40). The limit switches can be adjusted to a different vertical position by means of screw spindles (47, 48) for fixing the end positions of the door wing. <IMAGE></p> |
