Actuating drive for furniture flaps
First Claim
1. An actuating drive for moving a flap of an article of furniture, said actuating drive comprising:
- a housing;
an actuating arm mounted pivotably to or in the housing for moving the flap;
a spring device for applying force to the actuating arm;
a transmission mechanism for transmitting a force of the spring device to the actuating arm;
an adjusting device by which a lever geometry of the transmission mechanism and/or the force of the spring device acting on the actuating arm can be variably adjusted; and
a damping device configured to damp a movement of the actuating arm with a damping power in a damping stroke;
wherein the adjusting device is coupled to the damping device by a coupling device, such that, by an adjustment of the adjusting device via the coupling device, a position of the damping device relative to the housing and/or the damping stroke of the damping device and/or the damping power of the damping device can be variably adjusted;
wherein the spring device is configured to urge the actuating arm in the closing direction within a first range of pivotal angle and in the opening direction within a second range of pivotal angle, and the actuating arm has a dead point position between the first range and the second range of pivotal angle in which the actuating arm is urged by the spring device neither in the closing direction nor in the opening direction, the dead point position of the actuating arm being variably adjustable by the adjusting device;
wherein, starting from an operational commencement position of the actuating arm, the damping device damps a movement of the actuating arm, and by adjustment of the dead point position of the actuating arm by the coupling device, a corresponding displacement of the operational commencement position of the damping device is effected.

Abstract
An actuating drive for moving a flap includes a housing, an actuating arm pivotably mounted on or in the housing for the moving flap, a spring apparatus for applying force to the actuating arm, a transmission mechanism for transmitting a force of the spring apparatus onto the actuating arm, an adjusting apparatus by which a lever geometry of the transmission mechanism and/or the force of the spring apparatus, which force acts on the actuating arm, can be variably adjusted, and a damping apparatus by which a movement of the actuating arm can be damped by a damping power in the event of a damping stroke. The adjusting apparatus is coupled to the damping apparatus by a coupling apparatus, and the position of the damping apparatus relative to the housing, the damping stroke of the damping apparatus, and/or the damping power of the damping apparatus can be variably adjusted.
