FIELD: gate equipment.
SUBSTANCE: gates, which have a range of one behind the other in the direction of movement of the door leaf and pivotally connected to each other along the axes of the hinges of the door leaf links extending perpendicularly to a given trajectory, a system of guide rails, a drive device connected to the door leaf, and also a balancing device supporting the movement of opening the door leaf, characterized in that the ratio of the polygon of the radius of curvature of the arcuate section on its inner guiding surface to the height of at least one gate link in a direction running perpendicular to the hinge axes and approximately parallel to the specified predetermined trajectory is 0.6 or more, preferably 0.65, particularly preferably 0.665 or more, in particular about 0.68.
EFFECT: more efficient opening and closing of gates.
