  • Brake device for rotatable and spring loaded rods, foil or cloth material being attachable to said rods
    Patent number: 4188992
    Abstract: A braking device for roller blind spring loaded rods compressing a sleeve affixed to the end of the rod carrying therein several radially movable weight segments. The shaft upon which the rod rotates carries at least one non-rotatable braking element. The centrifugal force generated on the weight segments upon a rapid rotation of the rod forces the segments to press against the braking elements slowing the rod down by friction braking. The braking elements can be flange discs mounted on or affixed to the shaft.
