Abstract

A set of panels including a first panel with a first main plane and a second panel with a second main plane, wherein the first main plane is essentially perpendicular to the second main plane and a junction plane is extending between the first main plane and the second main plane, wherein the first and the second panel includes a mechanical locking device which is configured for locking a first junction plane surface of the first panel to a second junction plane surface of the second panel at the junction plane, wherein the mechanical locking device includes a rod-shaped element at the first or second junction plane surface configured to cooperate with a cylindrical shaped element groove at the opposite junction plane surface for locking the first and the second panel in a first direction which is perpendicular to the first main plane.

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 the first main plane is essentially perpendicular to the second main plane in a locked position of the first and the second panel and a junction plane is extending between the first main plane and the second main plane,
wherein the junction plane is in the locked position extending from an inner corner to an outer corner of the first and the second panel,
wherein the first and the second panel comprise a mechanical locking device which is configured for locking a first junction plane surface of the first panel to a second junction plane surface of the second panel at the junction plane,
wherein the first junction plane surface and the second junction plane surface extend along the junction plane,
wherein the mechanical locking device comprises a rod-shaped element at one of the first or second panel intersecting the junction plane and configured to cooperate with an element groove at the other one of the first or second panel for locking the first and the second panel in a first direction which is perpendicular to the first main plane,
wherein:
the one of the first or second panel comprises a locking groove and the other one of the first or second panel comprises a locking part configured to be inserted into the locking groove, wherein the locking groove is a fully blind hole with a bottom surface facing an opening of the locking groove,
the locking part comprises a locking surface configured to cooperate with a locking surface of the locking groove to lock the first and the second panel in a second direction,
the locking part is of a cylindrical shape, and
the cylindrical locking part is configured to be displaceable in an axial direction of the cylindrical locking part during a locking of the first panel to the second panel,

wherein the rod-shaped element protrudes from and intersects the first or second panel at a first surface of the first or second panel, and the locking groove is recessed from and extends to the first surface of the first or second panel.

2. The set of panels as claimed in claim 1 , wherein the locking part is flexible.

3. The set of panels as claimed in claim 1 , wherein the angle between the junction plane and the first main plane is about 45°.

4. The set of panels as claimed in claim 1 , wherein the locking surface of the locking groove is a part of the bottom surface of the locking groove.

5. The set of panels as claimed in claim 1 , wherein the locking surface of the locking groove is a part of a funnel shaped bottom of the locking groove.

6. The set of panels as claimed in claim 1 , wherein the mechanical locking device comprises a number of rod-shaped elements and a number of locking parts, wherein the number of rod-shaped elements is equal or greater than the number of locking parts.

7. The set of panels as claimed in claim 1 , wherein the locking part comprises polymer material.

8. The set at claimed in claim 1 , wherein the locking part comprises an elastic part.

9. The set as claimed in claim 1 , wherein the rod-shaped element is of an essentially cylindrical shape.

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

11. The set of panels as claimed in claim 10 , wherein the locking part has an elongated shape, where a length is greater than a width.

12. The set of panels as claimed in claim 10 , wherein the locking part during assembly of the first and the second panel is configured to flex in the depth direction of the locking part groove.

13. The set of panels as claimed in claim 1 , wherein the first and/or the second panel comprises a wood fiber based material.

14. The set of panels as claimed in claim 13 , wherein the first or second panel comprises a decorative layer.

15. The set of panels as claimed in claim 1 , wherein the first junction plane surface and/or the second junction plane surface comprises an edge groove which is configured to minimize the risk of a gap between the first and the second panel at the inner and/or the outer corner in the locked position of the first and the second panel.

16. The set of panels as claimed in claim 15 , wherein the edge groove is recessed to the first surface of the first or second panel.

17. The set of panels as claimed in claim 1 , wherein the locking part protrudes from and intersects the other one of the first or second panel at a second surface of the other one of the first or second panel, and the element groove is recessed from and extends to the second surface of the other one of the first or second panel.

18. The set of panels as claimed in claim 1 , wherein the locking groove is not a through hole.
