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.

METHOD OF DOOR CONTROL WITHOUT HAND CONTACTING AND THE DEVICE CARRYING OUT THIS METHOD
The method of door control without, hand contact, wherein, when the door leaf (1) is in its stationary closed position, all the energy necessary for automatic opening and subsequent closing the door leaf (1), initiated by an actuating force (39), preferably realized by means of a foot lever (34), is accumulated in an opening and closing mechanism (I) during the actuating action of the controlling mechanism (II). During the automatic opening, the only acting force is the tension of the opening member (14), and during the subsequent automatic closing, the only acting force is the tension of the closing member (17). By means of the bimodal opening and closing mechanism (I), the tensions of these two members act separately, not against each other.
E05F 1/14 - Closers or openers for wings, not otherwise provided for in this subclass spring-actuated for swinging wings with double-acting springs, e.g. for closing and opening or checking and closing

MECHANISM FOR OPTIMALIZATION OF DRIVING FORCE WITH CONTINUOUS AUTOMATIC SHIFT OF GEAR RATIO
Mechanism for optimalization of driving force with continuous automatic shift of gear ratio where depending on the angle of rotation of the first arm (11) which is firmly or adjustably connected to the second arm (13), whereas both arms are as a whole rotating around the pivot point (7), is automatically continuously set the shortest possible length of the connecting piece (4) between the first pulley (9) and the first freely movable mounting (5) of the first connecting piece (4), whereby is changed the working length of the first arm (11) and thus there occurs an automatic continuous shift of gear ratio between the first arm (11) and the second arm (13), whereas the position of the first connecting piece (4) remains during the whole time of the movement practically vertical to the first arm (11) and thus it is ensured that also the acting force is practically vertical to the first arm (11), whereby the part of force acting in the direction of the required movement is optimized. This mentioned mechanism eliminates the linear increase of force e.g. of a spring or other accumulator of force depending on travel and substitutes it with a constant size of force.
