An actuating drive for moving a flap of an item of furniture, including: an actuating arm pivotally mounted about a pivoting axis for moving the flap, a spring device for applying a force onto the actuating arm, a transmission mechanism for transmitting a force of the spring device onto the actuating arm in a closing direction and for transmitting a force of the spring device onto the actuating arm, and an adjusting device for adjusting a position of an actuating portion of the actuating drive in or along a guide. The actuating drive includes a coupling device coupling the spring device, the pivoting axis of the actuating arm, and the actuating portion to one another. By adjusting the actuating portion in or along the guide, the position of the dead-center of the actuating arm and the force of the spring device acting towards the opening direction can be variably adjusted. |

1. An actuating drive for moving a flap of an item of furniture, including:
at least one actuating arm which is pivotally mounted about a pivoting axis for moving the flap, a spring device for acting a force onto the actuating arm, a transmission mechanism for transmitting a force of the spring device onto the actuating arm in a closing direction and, after exceeding a dead-center position, for transmitting a force of the spring device onto the actuating arm in an opening direction, an adjusting device by way of which a position of an actuating portion of the actuating drive can be adjusted in or along a guide, wherein the actuating drive includes a coupling device which couples the spring device, the pivoting axis of the actuating arm and the actuating portion to one another, wherein by adjusting the actuating portion in or along the guide, the position of the dead-center of the actuating arm as well as the force of the spring device acting towards the opening direction onto the actuating arm can be variably adjusted, so that upon an increase of the force acting towards the opening direction, also the pivoting angle of the actuating arm, at which the position of the dead center lies, can be reduced. |
