A device for opening and closing a door has a manoeuvring device (17) which when moving in a direction brings about closing of the door and with movement in the other direction opening of the door. By means of a power generation device (18) a movable control element (19) is set up to control the movement of the manoeuvring device (17). The control element (19) works together with the manoeuvring device (17) through a connector, with the help of which the manoeuvring device and the control element are freely moving relatively to each other over a limited area of motion but movement of the control element in the opposite direction leads to influence on the manoeuvring device for opening and respectively closing of the door. The control element and manoeuvring device are movable front and backwards in a straightforward track of motion.<IMAGE> |
