Abstract

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, wherein the first panel includes a first edge surface, the second panel includes 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 at least one rod-shaped element at the first edge surface, at least one insertion groove at the second panel surface, the rod-shaped element is configured to be inserted into the insertion groove, the insertion groove extends into the second panel surface at a second angle from the second panel surface, a back panel, and at least one locking gear configured to cooperate with the back panel and a first and/or second panel groove.

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, the second panel comprises a second panel surface, the first edge surface is facing or parallel to the second panel surface in a locked position of the first and the second panel, the mechanical locking device comprises at least one rod-shaped element at the first edge surface and at least one insertion groove at the second panel surface, the rod-shaped element is configured to be inserted into the insertion groove, the rod-shaped element extends at a first angle from the first edge surface, the insertion groove extends into the second panel surface at a second angle from the second panel surface, the first angle is within the range of about 30° to about 60°, and the mechanical locking device further comprises:
a first panel groove on a first panel surface on the first panel, and a second panel groove on the second panel surface of the second panel,
a back panel configured to be inserted in and to cooperate with the first panel groove and the second panel groove, and
at least one locking gear comprising a lever arm, a locking head at a first end of the lever arm, and a locking part at a second end of the lever arm, wherein the first end is opposite of the second end, and wherein the at least one locking gear is configured for locking of the first panel to the second panel by inserting the locking head into the first panel groove and inserting the locking part into the second panel groove, or vice versa.

2 . The set as claimed in claim 1 , wherein a width of at least one of the first panel groove and the second panel groove minus a thickness of the back panel is larger than or essentially the same as an extension of the rod-shaped element along the first edge surface.

3 . The set as claimed in claim 1 , wherein the rod-shaped element is arranged in a rod element groove in the first edge surface.

4 . The set as claimed in claim 1 , wherein the width of the first panel groove is essentially the same as the width of the second panel groove.

5 . The set as claimed in claim 1 , wherein the first panel comprises a second edge surface, the second panel comprises a third edge surface, the first panel groove is substantially parallel to the second edge surface and the second panel groove is substantially parallel to the third edge surface.

6 . The set as claimed in claim 5 , wherein the first panel groove extends substantially along the entire second edge surface and the second panel groove extends essentially along the entire third edge surface.

7 . The set as claimed in claim 1 , wherein at least one of the first panel groove and the second panel groove is bottom-ended.

8 . The set as claimed in claim 1 , wherein the locking gear is flexible.

9 . The set as claimed in claim 1 , wherein an extension of the back panel from the first edge of the first panel, when the first panel, the second panel and the back panel have been assembled, is less than an extension of the rod shaped element from the first edge surface of the first panel.

10 . The set as claimed in claim 1 , wherein the locking head is an eccentric locking head.

11 . The set as claimed in claim 10 , wherein an outer part of the eccentric locking head is thicker than a part of the eccentric locking head adjacent a first end of the lever arm.

12 . The set as claimed in claim 10 , wherein an outer part of the eccentric locking head comprises a friction connection configured to cooperate with the first panel groove or the second panel groove.

13 . The set as claimed in claim 1 , wherein the lever arm is elastic and configured to bend during the insertion of the locking part into the first panel groove or the second panel groove.

14 . The set as claimed in claim 13 , wherein bending of the lever arm creates a locking force between the locking part and the first panel groove or the second panel groove.

15 . The set as claimed in claim 13 , wherein the locking gear comprises a polymer material.

16 . The set as claimed in claim 13 , wherein the locking gear comprises a thermoplastic material.
