FIELD: construction, windows. ^ SUBSTANCE: invention relates to the field of construction, in particular to shielding devices for windows. The invention allows for making a window blind which allows for transmission of light without raising or lowering of the blinds. The window blind, which can move between the closed and open positions, consists of an upper cross beam, several folding panels and over hanging cross beams. Each of the several folding panels has a pair of oppositely lying longitudinal sections and a front surface. The pair of oppositely lying longitudinal sections consists of upper and lower sections, cord, connecting the upper cross beam and panels. The cord is tied to each of the several panels opposite one of the oppositely lying longitudinal sections. The blind has an opening cord, tied to each panel near the longitudinal section, opposite the clamp and a vertical regulation mechanism, effectively linked to the opening cord for independent movement of the opening cord when the lower longitudinal section of each panel moves behind the front surface of the panel. ^ EFFECT: making of a blind, which allows for transmission of light without raising or lowering the blind. ^ 85 cl, 19 dwg |
