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.

First claim

The invention claimed is:

1. A set of panels forming a corner joint having an inner corner and an outer corner, 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 the first edge comprises an edge tongue that extends beyond the junction plane,
wherein the second edge comprises an edge groove at the junction plane, wherein 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,
wherein the edge tongue comprises a tongue groove between the edge groove and the inner corner,
wherein the edge groove comprises a flexible tongue arranged in an insertion groove, said flexible tongue is configured to cooperate with the tongue groove for locking together the first and the second edges in a second direction which is perpendicular to the second main plane,
wherein the mechanical locking device comprises a first space between the edge tongue and the edge groove at an opening of the edge groove and at the junction plane between the edge tongue and the outer corner in a locked position of the first and the second edge,
wherein the angle between the junction plane and the first main plane is about 45 degrees,
wherein the mechanical locking device comprises a first contact surface at the first edge and a second contact surface at the second edge, the first contact surface and the second contact surface are at the outer corner, in a locked position of the first and the second panel, and in the junction plane and are configured to cooperate, and
wherein a second edge surface of the second edge comprises a recess extending from the second contact surface to the edge groove to create to a second space extending in the junction plane from the first and the second contact surfaces and to the opening of the edge groove.

2. The set of panels as claimed in claim 1 , wherein edge tongue extends, from the junction plane, essentially in the second direction.

3. The set of panels as claimed in claim 1 , wherein a first side of the edge tongue comprises, at or near the junction plane, a first locking surface, and the edge groove comprises, at or near the junction plane, a second locking surface, wherein the first locking surface and the second locking surface are essentially parallel and are configured to cooperate for locking in the first direction.

4. The set of panels as claimed in claim 3 , wherein the edge tongue at a second side, which is opposite the first side, comprises a third locking surface and the edge groove comprises a fourth locking surface, wherein the third locking surface and the fourth locking surface are essentially parallel and are configured to cooperate at a distance from the junction plane for locking in the first direction.

5. The set of panels as claimed in claim 4 , 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.

6. The set of panels as claimed in claim 5 , 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.

7. The set of panels as claimed in claim 1 , wherein the first and the second contact surfaces are cooperating over a first width, in a direction from the inner corner to the outer corner, wherein said first width is in the range of about 5% to about 40% of an edge width of the first and/or second edge surface.

8. The set of panels as claimed in claim 1 , wherein the mechanical locking device comprises a third contact surface at the first edge and a fourth contact surface at the second edge, the third and the fourth contact surface are at the inner corner, in a locked position of the first and the second panel, and in the junction plane, and are configured to cooperate.

9. The set of panels as claimed in claim 8 , wherein the third and the fourth contact surfaces are cooperating over a second width, in a direction from h inner corner to the outer corner, wherein said second width is in the range of about 2% to about 20% of an edge width of the first and/or second edge surface.

10. 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.

11. The set of panels as claimed in claim 1 , wherein a first edge surface of the first edge comprises another recess extending from the first contact surface to the edge tongue.
