ABSTRACT:
A device is provided for changing the force acting on a spring operated reversibly rotatable shaft. The spring is arranged to be tensioned during the rotation of the shaft in one direction and then provides the rotation of the shaft in the opposite direction. The device comprises a rotatably mounted means which is arranged to be actuated by a second spring, and a gear reduction device which is inserted between the shaft and the rotatable means. The gear reduction device causes the rotatable means to rotate less than one revolution during the whole rotation of the shaft in one direction. The second spring is arranged to provide an additional force on the shaft over the gear reduction device.
