FIELD: construction.
SUBSTANCE: closing device with a curtain comprises a curtain, which has flexible side edges with a bulge. The curtain is arranged with a cord or several adjacent cords, which are not compressible in direction of their length and are located in parallel to the curtain side edges so that these edges could be acted at by a pushing force in their longitudinal direction to move the curtain in its closed position. The cord or cords are in neutral surface of edges formed during their bend and are fixed to the curtain in a non-detachable manner. The bulge is arranged with a flexible strip made of elastic material, where the cord or cords are inbuilt, as well as two belts arranged opposite to each other on each of the curtain sides.
EFFECT: invention will make it possible to increase reliability of structure.
