Abstract

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel. The first edge surface is facing the second panel surface in a locked position of the first and the second panel, the mechanical locking device includes a rod-shaped element at the first edge surface and an insertion groove at the second panel surface, the rod-shaped element is configured to be inserted into the insertion groove. A first locking groove at the first edge surface and a second locking groove at the second panel surface and a locking part, where the locking part is configured to be inserted into the first locking groove and the second locking groove. The locking part is configured to apply a locking force between the first and the second panel in an oblique direction in relation to the second panel surface.

First claim

The invention claimed is:

1. A set comprising a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, wherein
the first panel comprises a first edge surface,
the second panel comprises a second panel surface,
the first edge surface is facing the second panel surface in a locked position of the first and the second panel,
the mechanical locking device comprises at least one rod-shaped element at the first edge surface and at least one insertion groove at the second panel surface,
the rod-shaped element is configured to be inserted into the insertion groove,
the mechanical locking device further comprises at least one first locking groove at the first edge surface and at least one second locking groove at the second panel surface and at least one locking part,
the locking part is configured to be inserted into the first locking groove and the second locking groove,
the locking part is configured to apply a locking force between the first and the second panel in an oblique direction in relation to the second panel surface,
the oblique direction is at an acute angle to the second panel surface, and
the rod-shaped element extends at a first angle (α1) from the first edge surface, wherein the first angle is within the range of about 10° to 80°.

2. The set as claimed in claim 1 , wherein the locking part is configured to pull the first panel and the second panel together in an assembly direction.

3. The set as claimed in claim 1 , wherein the rod-shaped element is configured to cooperate with the insertion groove to guide the first and second panel together during assembly.

4. The set as claimed in claim 1 , wherein the rod-shaped element is configured to cooperate with the insertion groove to guide the first and second panel to the locked position by a displacement of the second panel surface relative the first edge surface in a first direction and/or a second direction.

5. The set as claimed in claim 1 , wherein the insertion groove extends into the second panel surface at a second angle from the second panel surface, wherein the second angle is within the range of about 10° to 80°.

6. The set as claimed in claim 1 , wherein said first locking groove extends at a third angle from the first edge surface, wherein the third angle is within the range of about 10° to 80°.

7. The set as claimed in claim 1 , wherein said second locking groove extends at a fourth angle from the second panel surface, wherein the fourth angle is within the range of about 10° to 80°.

8. The set as claimed in claim 1 , wherein the insertion groove extends into the second panel surface at a second angle from the second panel surface, wherein said first locking groove extends at a third angle from the first edge surface, wherein said second locking groove extends at a fourth angle from the second panel surface, and wherein the first angle, the second angle, the third angle and the fourth angle are all #90°.

9. The set as claimed in claim 1 , wherein the insertion groove extends into the second panel surface at a second angle from the second panel surface, wherein said first locking groove extends at a third angle from the first edge surface, wherein said second locking groove extends at a fourth angle from the second panel surface, and
wherein the first angle, the second angle, the third angle and the fourth angle are essentially the same.

10. The set as claimed in claim 1 , wherein the locking part is a screw.

11. The set as claimed in claim 10 , wherein the screw extends into the second panel during assembly.

12. The set as claimed in claim 1 , wherein the first panel comprises a second edge surface which is adjacent the first edge surface, wherein the first locking groove extends from the second edge surface to the first edge surface.

13. The set as claimed in claim 1 , wherein the locking part is of the type cam and dowel connector.

14. The set as claimed in claim 13 , wherein the cam and dowel connector comprises at least one bolt and at least one connector housing.

15. The set as claimed in claim 14 , wherein the bolt of the cam and dowel connector is positioned in the first locking groove before assembly of the first panel and the second panel.

16. The set as claimed in claim 14 , wherein the connector housing is positioned in a first opening on the first panel.

17. The set as claimed in claim 1 , wherein the set comprises a first panel groove on a first panel surface-of the first panel, and a second panel groove on the second panel surface of the second panel.

18. The set as claimed in claim 17 , wherein the set further comprises a back panel configured to be inserted in, and optionally to cooperate with, the first and second panel groove.

19. The set as claimed in claim 16 , wherein the first opening is positioned between a first panel groove located on a first panel surface of the first panel and a second edge surface of the first panel.

20. The set as claimed in claim 16 , wherein the insertion groove, the first locking groove, the second locking groove and/or the first opening is a drill hole.

21. The set as claimed in claim 20 , wherein the drill hole is a bottom-ended drill hole.

22. The set as claimed in claim 1 , wherein the locking part is configured to cooperate with the first locking groove and/or the second locking groove.

23. The set as claimed in claim 1 , wherein the first edge surface comprises one first locking groove and the second panel surface comprises one second locking groove.

24. The set as claimed in claim 1 , wherein the rod-shaped element is arranged in a rod-element groove at the first edge surface.

25. The set as claimed in claim 1 , wherein the number of rod-shaped elements at the first edge surface is the same as the number of insertion grooves at the second panel surface.

26. A set comprising a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, wherein
the first panel comprises a first edge surface,
the second panel comprises a second panel surface,
the first edge surface is facing the second panel surface in a locked position of the first and the second panel,
