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 panel includes a first edge surface and a first panel surface, and the second panel includes a second edge surface and 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 includes a rod-shaped element at the first edge surface and an insertion groove at the second panel surface and an edge groove at the second edge surface and a flexible tongue positioned in the edge groove. The rod-shaped element includes a recess and is configured to be inserted into the insertion groove. The flexible tongue is configured to cooperate with the recess for a locking of the first panel to the second panel.

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 and a first panel surface, wherein the second panel comprises a second edge surface and a second panel surface, wherein the first edge surface is facing the second panel surface in a locked position of the first and second panels, wherein: the mechanical locking device comprises a cylindrical rod-shaped element at the first edge surface and a cylindrical insertion groove at the second panel surface,
the mechanical locking device comprises an edge groove at the second edge surface and a longitudinal flexible tongue positioned in the edge groove and extending transversely to the cylindrical insertion groove, the edge groove being a longitudinal groove that extends in a longitudinal direction of the second edge surface, and the edge groove extending from the second edge surface to the insertion groove,
the rod-shaped element comprises a recess,
the rod-shaped element is configured to be inserted into the insertion groove, and
the flexible tongue is configured to cooperate with the recess for a locking of the first panel to the second panel in a first direction which is perpendicular to the second panel surface.

2. The set as claimed in claim 1 , wherein the insertion groove extends from the second panel surface to the edge groove.

3. The set as claimed in claim 1 , wherein the mechanical locking device is configured to automatically lock the first panel to the second panel when the rod-shaped element is inserted into the insertion groove and the first edge surface is arranged against the second panel surface.

4. The set as claimed in claim 1 , wherein the rod-shaped element has a longitudinal shape with a length direction which is parallel to the first panel surface.

5. The set as claimed in claim 1 , wherein a second cross cut of the insertion groove, in a plane parallel to the second panel surface, has a shape that matches a first cross cut of the rod-shaped element, in a plane parallel to the second panel surface.

6. The set as claimed in claim 1 , wherein the insertion groove is a bottom-ended groove comprising a bottom surface which is positioned at a distance from the edge groove.

7. The set as claimed in claim 6 , wherein the insertion groove has a first part on a first side of the edge groove and a second part on a second side of the edge groove, wherein the second part comprises the bottom surface and side walls, wherein, in a locked position, the rod-shaped element passes through the first part of the insertion groove, through the edge groove and into the second part of the insertion groove.

8. The set as claimed in claim 7 , wherein the rod-shaped element is configured to cooperate with the side walls of the second part of the insertion groove.

9. The set as claimed in claim 7 , wherein the rod-shaped element is configured to cooperate with the bottom surface.

10. The set as claimed in claim 6 , wherein the insertion groove is a bottom-ended drill hole.

11. The set as claimed in claim 1 , wherein the first edge surface comprises two or more of said rod shaped element and the second panel surface comprises two or more of said insertion groove, wherein each of the rod-shaped elements is configured to be inserted into one of the insertion grooves.

12. The set as claimed in claim 11 , wherein the two or more of said insertion groove are arranged linearly.

13. The set as claimed in claim 1 , wherein the edge groove is a bottom-ended groove, comprising a bottom surface which is positioned at a distance from the insertion groove.

14. The set as claimed in claim 13 , wherein the flexible tongue is arranged at the bottom surface of the edge groove.

15. The set as claimed in claim 14 , wherein the rod-shaped element is configured to be attached in an attachment groove in the first edge surface.

16. The set as claimed in claim 13 , wherein the flexible tongue is arranged between the recess and the bottom surface of the edge groove in the locked position.

17. The set as claimed in claim 1 , wherein the second edge surface is essentially perpendicular to the second panel surface.

18. 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 and a first panel surface, wherein the second panel comprises a second edge surface and a second panel surface, wherein the first edge surface is facing the second panel surface in a locked position of the first and second panels, wherein: the mechanical locking device comprises a cylindrical rod-shaped element at the first edge surface and a cylindrical insertion groove at the second panel surface,
the mechanical locking device comprises an edge groove at the second edge surface and a longitudinal flexible tongue positioned in the edge groove and extending transversely to the cylindrical insertion groove, the edge groove being a longitudinal groove that extends in a longitudinal direction of the second edge surface,
the rod-shaped element comprises a recess,
the rod-shaped element has a longitudinal shape with a length direction which is transverse to the first edge surface and to the second panel surface in the locked position of the first and second panels,
the rod-shaped element is configured to be inserted into the insertion groove, and
the flexible tongue is configured to cooperate with the recess for a locking of the first panel to the second panel in a first direction which is perpendicular to the second panel surface.
