Counterbalanced window operators |
摘要 |
A counterbalanced operator for a pivoting unit includes a housing 17 and a rotatable drive member mounted in the housing. A first end 29a of arm member 29 is operatively connected to the drive member. A second end of the arm member is operatively connected to the pivoting end of the unit and a torque from the unit is transmitted to the arm member. A crank 33 rotates the drive member. A spring 40 provides for a means for counterbalancing the torque on the arm member. The spring 40 creates a force, the spring operatively connected to the arm member and the spring positioned in the housing. The force is transmitted from the spring to the arm member.
