Abstract

A set of panels including a first panel with a first main plane and a second panel with a second main plane. The first and the second panel are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel at a junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane. The first edge includes an edge tongue that extends from the junction plane. The second edge includes an edge groove at the junction plane. The edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in a first direction which is perpendicular to the first main plane. The edge tongue includes a tongue groove.

7. The set of panels as claimed in claim 6 , wherein the third locking surface and the fourth locking surface cooperate at an area extending over a first distance in the second direction, wherein the third locking surface and the fourth locking surface are displaced from the junction plane by a second distance, wherein the first distance is within the range of about 20% to about 200% of the second distance.

8. The set of panels as claimed in claim 7 , wherein the first side of the edge tongue, at a distance from the junction plane, comprises a fifth locking surface and the edge groove comprises a sixth locking surface at a distance from the junction plane, wherein the fifth locking surface and the sixth locking surface are essentially parallel and are configured to cooperate for locking in the first direction.

9. The set of panels as claimed in claim 1 , wherein the first panel comprises an inner half and an outer half in a direction of a thickness of the first panel, wherein the entire edge tongue is at the inner half of the first panel.

10. A set of panels for a furniture, the set comprising a first panel with a first main plane and a second panel with a second main plane, wherein the first panel and the second panel are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel at a junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane, wherein:
