Abstract

A furniture flap drive is provided with a first component having an electric motor and with a second component having an adjustment arm, wherein the first component and the second component can be fastened releasably to each other, and a force transmission device is provided to move the adjustment arm, wherein a positioning device can be used to adjust the position of the force transmission device, and wherein the first component can be fastened to the second component in at least two, preferably at least three, different positions of the adjustment arm.

Claims

1. A furniture flap drive comprising a first component having an electric motor and a second component having an actuating arm, wherein the first component and the second component can be releasably fastened together and there is provided a force transmission device for moving the actuating arm, wherein there is provided a positioning device with which the position of the force transmission device can be adjusted corresponding to at least two different angle positions of the actuating arm, wherein each angle position of the actuating arm has a different angle range between two end positions for actuating a different type of furniture flap, with the first end position being a closed position in which the furniture flap substantially bears against a furniture carcass, and the second end position being an open position of the furniture flap, wherein adjustment of the force transmission device allows only one kind of first component to be used with various types of furniture flaps.

2. A furniture flap drive as set forth in claim 1, wherein the first component can be fastened to the second component in at least three different positions of the actuating arm.

3. A furniture flap drive as set forth in claim 1, wherein the various positions of the force transmission device correspond to various opening angles of the actuating arm.

4. A furniture flap drive as set forth in claim 1, wherein the force transmission device is arranged on the first component and is configured to be brought into engagement with an interface on the actuating arm.

5. A furniture flap drive as set forth in claim 4, wherein the interface is in the form of a receiving opening.

6. A furniture flap drive as set forth in claim 1, wherein the force transmission device is in the form of a pin.

7. A furniture flap drive as set forth in claim 1, wherein the force transmission device is arranged on an eccentric transmission.

8. A furniture flap drive as set forth in claim 1, wherein the positioning device has at least one abutment element with which the force transmission device is movable.

9. A furniture flap drive as set forth in claim 8, wherein the force transmission device is displaceably movable by at least one abutment element.

10. A furniture flap drive as set forth in claim 1, wherein the positioning device has at least one actuating element.

11. A furniture flap drive as set forth in claim 10, wherein the positioning device has two actuating elements.

12. A furniture flap drive as set forth in claim 1, further comprising at least one locking element for fixing the first component to the second component.

13. A furniture flap drive as set forth in claim 12, wherein the at least one locking element is actuable by the positioning device.

14. A furniture flap drive as set forth in claim 12, wherein the at least one locking element is arranged on the positioning device.

15. A furniture flap drive as set forth in claim 12, wherein the at least one locking element is in the form of a hooked projection.

16. A furniture flap drive as set forth in claim 12, wherein the at least one locking element is configured to be brought into engagement with an abutment element is to be arranged on the second component.

17. A furniture flap drive as set forth in claim 1, further comprising an indicator device for indicating fastening of the first component to the second component.

18. A furniture flap drive as set forth in claim 17, wherein the indicator device is configured to indicate locking of the first component to the second component.

19. A furniture flap drive as set forth in claim 18, wherein the indicator device is actuable by at least one locking element.

20. A furniture flap drive as set forth in claim 17, wherein the indicator device is of a resilient nature or is spring-loaded.

21. A furniture flap drive as set forth in claim 18, wherein the indicator device is of a resilient nature or is spring-loaded.

22. An article of furniture comprising a furniture carcass and a flap mounted movably to the furniture carcass, wherein a furniture flap drive as set forth in claim 1 is mounted to the furniture carcass, and wherein the actuating arm of the furniture flap drive is connected to the flap.
