发明名称 Lift system having length adjustment for window blinds
摘要 An axle driven cord collection system that uses cones to spool the lift cords. An idle/drive wheel on each cone prevents the cords from tangling. A collet connects each cone in an adjustable way so that the total travel of each cord can be precisely controlled by adjusting the position of the starting wrap on at least one of the cones.
