FIELD: construction. ^ SUBSTANCE: invention is related to the field of construction, namely to facilities for openings closure and opening. Closing facility for architectural opening comprises extensible material installed with the possibility of displacement from extended position for opening closure to shut position to open the opening, drive cord wound around collar, the first end of which is fixed on coil installed with the possibility of rotation, with the possibility of its stretching from driving coil or from extensible material, which is displaced either in vertical or horizontal direction, or from displacing spring in case of vertical or horizontal displacement of extensible material. The second end of cord is fixed to free-hanging weight with the possibility of stretching under action of free-hanging weight. ^ EFFECT: provision of linear motion transformation into rotary one with application of cord drive. ^ 29 cl, 161 dwg |
