Abstract

A set of panels including a first panel with a first main plane and a second panel with a second main plane. A first edge of the first panel is configured to be locked to a second edge of the second panel, wherein the first main plane is essentially perpendicular to the second main plane, and wherein the first and the second edges are locked in a first direction, which is perpendicular to the first main plane, and a second direction, which is perpendicular to the second main plane. The first edge includes an edge tongue, with a longitudinal direction along the first edge, including a bottom edge, a first surface and an opposite second surface. The edge groove and/or the edge tongue is/are configured such that a greater force is absorbed by the longitudinal central part than by an edge part at third and fourth edges.

First claim

The invention claimed is:

1. A set of panels comprising a first panel with a first main plane and a second panel with a second main plane, wherein a first edge of the first panel is configured to be locked to a second edge of the second panel, wherein the first main plane is essentially perpendicular to the second main plane, and wherein the first and the second edges are locked in a first direction, which is perpendicular to the first main plane, and a second direction, which is perpendicular to the second main plane, wherein the first edge comprises an edge tongue, with a longitudinal direction along the first edge, comprising a bottom edge, a first surface and an opposite second surface, wherein the second edge comprises an edge groove, with a longitudinal direction along the second edge, comprising a bottom, a first surface and an opposite second surface, wherein the edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in the first direction, wherein:
the first surface of the edge tongue is configured to cooperate, at a longitudinal central part of the first edge and the second edge, with the first surface of the edge groove for said locking in the first direction,
the first panel comprises a third edge which is adjacent to the first edge and the second panel comprises a fourth edge which is adjacent to the second edge,
the edge groove extends to the fourth edge, and
the edge groove and/or the edge tongue is/are configured such that a greater force is absorbed by the longitudinal central part than by an edge part of the first edge and the second edge at the third and fourth edges, when a load is applied to the first and/or the second panel.

2. The set of panels as claimed in claim 1 , wherein the edge groove has a first groove shape at the edge part and a second groove shape at the longitudinal central, wherein the first groove shape is different from the second groove shape.

3. The set of panels as claimed in claim 1 , wherein the edge tongue has a first tongue shape at the edge part and a second tongue shape at the longitudinal central, wherein the first tongue shape is different from the second tongue shape.

4. The set of panels as claimed in claim 1 , wherein the edge part has a longitudinal length in the range of about 5 mm to about 50 mm in the longitudinal direction of the edge groove.

5. The set of panels as claimed in claim 1 , wherein a third surface of the edge tongue is configured to be at a distance, at said edge part, from a third surface of the edge groove, in a locked position of the first and the second edges, wherein the third surface of the edge tongue is at a same position, in the second direction, and on a same side of the edge tongue as the first surface of the edge tongue, and wherein the third surface of the edge groove is at a same position, in the second direction, and on a same side of the edge groove as the first surface of the edge groove.

6. The set of panels as claimed in claim 1 , wherein a first thickness of the edge tongue, at the longitudinal central part and at the first surface of the edge tongue, is greater than a second thickness of the edge tongue, at the edge part and at a same position, in the second direction, as the first thickness.

7. The set of panels as claimed in claim 1 , wherein a first width of the edge groove, at the edge part, is greater than a second width of the edge groove, at the longitudinal central part, wherein the second width is at the first surface of the edge groove and the first width is at a same position, in the second direction, as the second width.

8. The set of panels as claimed in claim 1 , wherein a second distance, which is between the bottom edge and the bottom and at the edge part, is greater than a first distance, which is between the bottom edge and the bottom and at the longitudinal central part, in a locked position of the first and the second edges.

9. The set of panels as claimed in claim 1 , wherein edge tongue extends over the longitudinal central part and ends before the edge part.

10. The set of panels as claimed in claim 1 , wherein the first surface of the edge tongue and the first surface of edge groove are closer to an outer corner of the first and the second edges, in a locked position of the first and the second edges, than the second surface of the edge tongue and the second surface of the edge groove.

11. The set of panels as claimed in claim 1 , wherein the edge tongue comprises a tongue groove and the edge groove comprises a tongue, said tongue is configured to cooperate with said tongue groove for locking together the first and the second edges in the second direction.

12. The set of panels as claimed in claim 9 , wherein the tongue is a flexible tongue arranged in an insertion groove.

13. The set of panels as claimed in claim 10 , wherein the insertion groove extends along essentially the entire length of the edge groove.

14. The set of panels as claimed in claim 10 , wherein the flexible tongue is displaceable in the insertion groove.

15. The set of panels as claimed in claim 1 , wherein the edge groove extends along essentially the entire length of the second edge.

16. The set of panels as claimed in claim 1 , wherein a core material of the first and the second panel comprises a wood fibre based board, such as a HDF, MDF, plywood, solid wood or particleboard, or a reinforced plastic board or a wood fibre composite board.

17. The set of panels as claimed in claim 16 , wherein the core is provided with a decorative layer.
