4. The actuating device as set forth in claim 1 , wherein there is provided an arresting device for releasably arresting the first lever relative to the second lever in the mounting position of the actuating arm lever.

5. The actuating device as set forth in claim 4 , wherein the arresting device includes precisely two recesses cooperating with the spring element, wherein the precisely two recesses further cooperate with the at least one protrusion.

6. The actuating device as set forth in claim 1 , wherein there is provided a force storage means for acting on the actuating arm lever with a movement force for movement of the furniture part.

7. The actuating device as set forth in claim 6 , wherein the arresting of the first lever relative to the second lever is releasable by action of the movement force.

8. The actuating device as set forth in claim 6 , wherein the first lever is moveable relative to the second lever by the action of the movement force into the operating position.

9. The actuating device as set forth in claim 1 , wherein there is provided a guide means for movements of the first lever relative to the second lever.

10. The actuating device as set forth in claim 1 , wherein the locking device includes only one spring element.

11. The actuating device as set forth in claim 10 , wherein a transverse extent of the spring element transversely with respect to a relative axis of movement of the first lever relative to the second lever can be reduced by an action against a spring force of the spring element.

12. The actuating device as set forth in claim 11 , wherein the spring element is in a form of a shaped portion with at least one protrusion determining the transverse extent and a spring zone for producing the spring force.

13. The actuating device as set forth in claim 1 , wherein the moveably mounted furniture part is in a form of a flap pivotable with respect to a horizontal axis.

14. An article of furniture comprising two actuating devices, as set forth in claim 1 .

15. A method of mounting a moveable furniture part to a furniture carcass by means of at least one actuating device as set forth in claim 1 , wherein the furniture part is moveable between an opened position and a closed position, wherein by the following steps:

a) fixing the at least one actuating device to the furniture carcass, wherein the first lever is disposed in the mounting position relative to the second lever of the at least one actuating device,

b) fixing the moveable furniture part to the first lever, and

c) moving the first lever relative to the second lever into the operating position by moving the moveable furniture part towards the closed position or the opened position.

16. The actuating device as set forth in claim 1 , wherein there is provided an arresting device for releasably arresting the first lever relative to the second lever in the mounting position of the actuating arm lever; where the arresting device includes only one spring element.

17. An actuating device for moveably mounting a furniture part to a furniture carcass comprising an actuating arm lever, wherein a first lever of the actuating arm lever is moveable relative to a second lever of the actuating arm lever from a mounting position into an operating position, wherein the first lever is lockable relative to the second lever by means of an automatic locking device in the operating position, wherein there is provided a guide means for movements of the first lever relative to the second lever, and wherein the guide means has a slot and a guide pin cooperating with the slot, wherein the slot is arranged on one of the first lever and the second lever and the guide pin is fixed to the other of the first lever and the second lever.

18. An actuating device for moveably mounting a furniture part to a furniture carcass comprising an actuating arm lever, wherein a first lever of the actuating arm lever is moveable relative to a second lever of the actuating arm lever from a mounting position into an operating position, wherein the first lever is lockable relative to the second lever by means of an automatic locking device in the operating position, wherein the locking device includes only one spring element, and wherein the spring element includes at least one projection which by cooperation with an opening on the first lever or on the second lever limits relative movements of the spring element relative to the first lever or to the second lever.

19. An actuating device for moveably mounting a furniture part to a furniture carcass comprising an actuating arm lever, wherein a first lever of the actuating arm lever is moveable relative to a second lever of the actuating arm lever from a mounting position into an operating position, wherein the first lever is lockable relative to the second lever by means of an automatic locking device in the operating position, wherein the locking device includes only one spring element, and wherein the locking device includes precisely two openings cooperating with the spring element, wherein the precisely two openings preferably cooperate with the at least one protrusion.
