The present invention relates to a device for automatic control of a swinging wing. The device according to the invention consists in moving a screw rod (8) with large pitch in the axis of the hinges (3) of the wing (1) using a pneumatic jack (13) situated on one of its ends. The body of the jack, being solidly attached to the window frame by means of a tube (10) and a lug (11), transmits a vertical translational movement of the screw (8) which, by means of a nut (7) fixed to the lower hinge arm (2) of the wing (1), creates a rotational movement. The reaction of the torque resulting from this action is taken up by a guide member (9) for the rod in its top part (10) fixed to the wall (4). <IMAGE> |
