Mechanism for controlling the rotation of a roller blind winding roller having a spring drive

摘要

One embodiment of a mechanism for controlling the rotation of a roller blind winding roller having a spring drive and immovably fixed to a roller blind holder and its winding roller is constructed of an inner shaft (1), on which a sleeve (2) is rotationally seated. In the sleeve (2) there is rotationally seated an inner roller (4), and between the sleeve (2) and the inner roller (4) there is an annular slot (5) filled with a braking layer (26) formed from high viscosity medium. The inner roller (4) contains a formed driver (6) and in the sleeve (2), between the inner roller (4) and the inner shaft (1) there is a brake shoe (3) seated with its pin (9) in the opening (7) of the inner shaft (1), and a relief (8) where the driver (6) of the inner roller (4) is seated.
