Abstract

An actuating drive includes an actuating arm pivotally mounted about a pivoting axis for moving the movable furniture part, a spring device for applying a force onto the actuating arm, and a transmission mechanism for transmitting a force of the spring device onto the actuating arm. The transmission mechanism includes an actuating portion movement-coupled to the actuating arm, a setting contour, and a pressure portion pressurized by the spring device. The pressure portion is a rotatably mounted pressure roller for running along the setting contour. The setting contour is arranged between the actuating portion and the pressure roller, and the setting contour is on a contour portion separate from the actuating portion. The contour portion has a fastening section configured to rest against the actuating portion and a limb protruding transversely from the fastening section, and the setting contour is a curved outer surface of the limb.

First claim

The invention claimed is:

1. An actuating drive for moving a movable furniture part, comprising:
an actuating arm pivotally mounted about a pivoting axis for moving the movable furniture part;
a spring device for applying a force to said actuating arm; and
a transmission mechanism for transmitting a force from said spring device to said actuating arm, said transmission mechanism including:
an actuating portion movement-coupled to said actuating arm;
a contour portion separate from said actuating portion and formed of bent or deep-drawn metal, said contour portion having (a) a fastening section configured to rest against said actuating portion, and (b) a limb protruding transversely from said fastening section such that a setting contour is formed by a curved radially outer surface of said limb; and
a pressure portion pressurized by said spring device, said pressure portion being a rotatably mounted pressure roller configured to run along said setting contour upon a movement of said actuating arm, said setting contour being arranged between said actuating portion and said pressure roller.

2. The actuating drive according to claim 1 , wherein said limb of said contour portion protrudes transversely from said fastening section of said contour portion in a direction parallel to said pivoting axis of said actuating arm.

3. The actuating drive according to claim 1 , wherein said limb has a width corresponding to a width of said pressure roller.

4. The actuating drive according to claim 1 , wherein said fastening section of said contour portion includes a fastening location for fixing said contour portion to said actuating portion.

5. The actuating drive according to claim 4 , wherein said fastening location is arranged eccentrically in relation to said pivoting axis of said actuating portion.

6. The actuating drive according to claim 1 , wherein said contour portion is movement-coupled to said actuating portion such that, upon a movement of said actuating portion, said contour portion also moves with said actuating portion.

7. The actuating drive according to claim 1 , wherein said actuating portion is pivotally mounted about an actuating pivoting axis.

8. The actuating drive according to claim 7 , wherein said actuating pivoting axis is also said pivoting axis of said actuating arm.

9. The actuating drive according to claim 7 , wherein said actuating portion has a peripheral surface on an end region facing towards said actuating pivoting axis, said peripheral surface being radially spaced from said actuating pivoting axis, said peripheral surface being at least partly covered by said limb and setting contour of said contour portion.

10. The actuating drive according to claim 9 , wherein said contour portion is a first contour portion fixed to a first side of said actuating portion, said actuating drive further comprising a second contour portion fixed to a second side of said actuating portion, said setting contour of said first contour portion and a setting contour of said second contour portion being arranged to rest against each other and thereby at least partly cover said peripheral surface of said actuating portion.

11. The actuating drive according to claim 1 , wherein said actuating portion is located on said actuating arm.

12. The actuating drive according to claim 1 , wherein said spring device includes a coil spring.

13. The actuating drive according to claim 12 , wherein said coil spring is a pressure spring.

14. The actuating drive according to claim 1 , wherein said pivoting axis of said actuating arm is configured to extend in a horizontal direction in a mounting position, and said pivoting axis and said spring device are configured such that said spring device acts upon said actuating arm about said pivoting axis in an opening direction.

15. The actuating drive according to claim 1 , wherein said pressure roller is a double-tapered roller having two tapered cones connected to each other.

16. The actuating drive according to claim 15 , wherein said tapered cones are connected to each other by respective bases.

17. An arrangement comprising:
a movable furniture part; and
said actuating drive according to claim 16 for moving said movable furniture part.
