The subject of invention is a mechanism controlling the rotation of roller blinds winding roller with a spring drive, especially a window blinds, when rolling or unrolling the sunshade.
There are known restraining devices containing decelerating structure, connected with roller blinds spring drive, described as toothed planetary gear unit with a central wheel, planet wheels and ring gear. A rotor is joint with the central wheel and planet wheels are rotationally seated on unidirectional coupling, while the ring gear is rotationally joint with a roller, hollowed along its entire length of which the two ends are rotationally joint with a couple of bearing pivots. The edge of the sunshade is joint with the roller, and inside the roller there is an immobile middle rod, joint with one of the bearing pivots. A spring, functionally adjusted to impart rotation of the roller in the first direction round its first axis and to pull in the sunshade, is joint with the middle rod and with the roller. In the roller there is located a fluid brake, functionally connected with the roller and middle rod, restraining rotation of the roller in its first direction. A chamber of the liquid brake is rotationally joint with the roller.
