SPRING SYSTEM FOR ROLLER BLINDS
A spring assist module for window covering includes a stationary member, at least one torsion spring, and at least one rotatable member. The stationary member may be connectable to an operating member of the window covering. The at least one rotatable member may be keyable to a driven part of the window covering, such that rotation of the driven part rotates the at least one rotatable member. The at least one torsion spring may include a first end operatively coupled to the stationary member and a second end operatively coupled to the at least one rotatable member. During the use, once the rotatable member rotates in the rotation direction, the torsion spring can store the kinetic energy of the rotatable member, and once the rotatable member rotates in the direction opposite to the rotation direction, the kinetic energy stored by the torsion spring can be released to the rotatable member.
