FIELD: construction. ^ SUBSTANCE: prefabricated structure of an architectural opening cover comprises two side bars for parallel installation at opposite appropriate sides of the architectural opening; and at least one moved end bar, arranged perpendicularly between two side bars for its displacement along two side bars, which is equipped with a cord device, which continues along the side bars and a moved end bar, for reliable fixation of the moved end bar in any position of its arrangement on two side bars. The cord device also fixes each end of the moved end bar to an appropriate side bar so that when two side bars and a moved end bar are not fixed as adjacent to the architectural opening, two side bars and a moved end bar remained fixed together as a single prefabricated structure. ^ EFFECT: invention will make it possible to simplify design of the device. ^ 29 cl, 36 dwg |
