Abstract: The method of door control without, hand contact, wherein, when the door leaf is in its stationary closed position, all the energy necessary for automatic opening and subsequent closing the door leaf, initiated by an actuating force, preferably realized by means of a foot lever, is accumulated in an opening and closing mechanism during the actuating action of the controlling mechanism. During the automatic opening, the only acting force is the tension of the opening member, and during the subsequent automatic closing, the only acting force is the tension of the closing member. By means of the bimodal opening and closing mechanism, the tensions of these two members act separately, not against each other.
