Actuator for movable furniture parts

摘要

An actuator for moving a movable furniture part includes at least one movably mounted actuating member for moving the movable furniture part, a spring device for applying a force to the actuating member, and a setting device by which a force of the spring device that acts on the actuating member can be set. The setting device has a threaded portion and a screw nut mounted adjustably between two end positions, and the force of the spring device acting on the actuating member can be set by adjusting the screw nut along the threaded portion. At least one supporting element is provided which relieves the screw nut in at least one of the two end positions of the force of the spring device.
