A core material of the panels in the embodiments above preferably comprises a wood 5 fibre based board, such as a HDF, MDF, plywood, solid wood or particleboard, a reinforced plastic board, or a wood fibre composite board.
Claims
5 10 15 20 25 Date Refue / Date Received 2023-09-11 84214761 14 CLAIMS:
1. A set of panels comprising a panel with a first main plane and an adjacent panel with a second main plane, wherein the panel and the adjacent panel comprise an angleable locking device for locking a first edge of the panel to a second edge of the adjacent panel, wherein the first main plane is essentially perpendicular to the second main plane, wherein the first main plane is parallel to an outer surface of the panel and the second main plane is parallel to an outer surface of the adjacent panel wherein the angleable locking device comprises an edge groove at the first edge and a tongue groove at the second edge, the edge groove comprises a flexible tongue arranged in an insertion groove at a first side of the edge groove, said flexible tongue is configured to cooperate with the tongue groove for locking together the first and the second edges in a first direction which is perpendicular to the first main plane, wherein the angleable locking device further comprises contact surfaces between the edge groove and the second edge at the first side and at a second side, respectively, of the edge groove for locking together the first and the second edges in a second direction which is parallel to the first main plane, wherein the angleable locking device is configured to be unlocked by an angling motion of die panel relative the adjacent panel, such that an angle between the first and the second main plane increases, wherein the angleable locking device is configured such that the flexible tongue moves out of the tongue groove by the angling motion, and wherein the angleable locking device comprises a first space between the first edge of the panel and the second edge of the adjacent panel, wherein the first space is positioned at a second side of the edge groove, which is opposite the first side of the edge groove, and wherein the first space is positioned at an opening of the edge groove in a locked position of the panel and the adjacent panel, and wherein said first space is between a bevel of the first edge of the panel and a recess at the second edge of the adjacent panel.
2. A set of panels as claimed in claim 1, wherein the set of panels is for a furniture product. 5 10 15 20 25 Date Refue / Date Received 2023-09-11 84214761 15 3. The set of panels as claimed in claim 1 or claim 2, wherein the angleable locking device comprises cooperating surfaces at a first side of the opening of the edge groove in a locked position of the panel and the adjacent panel.
4. The set of panels as claimed in claim 1 or claim 2, wherein the angleable locking device comprises cooperating surfaces at a first side of the opening of the edge groove in a locked position of the panel and the adjacent panel at an inner comer of the panel and the adjacent panel.
5. The set of panels as claimed in any one of claims 1-4, wherein the angleable locking device comprises a recess at a first and / or a second outer edge for enabling said angling motion.
6. The set of panels as claimed in claim 5, wherein the recess comprises a bevel.
7. The set of panels as claimed in any one of claims 1 to 6, wherein the angleable locking device comprises a second space between an outer edge of the second edge and the edge groove at the first side of the edge groove for enabling said angling motion.
8. The set of panels as claimed in any one of claims 1 to 7, wherein the edge groove extends along essentially the entire length of the second edge.
9. The set of panels as claimed in any one of claims 1 to 8, wherein the flexible tongue is displaceable in the insertion groove.
10. The set of panels as claimed in any one of claims 1 to 9, wherein the angleable locking device comprises a third space between an outermost surface of the second edge and the edge groove.
11. The set of panels as claimed in any one of claims 1 to 10, wherein the angleable locking device comprises cooperating surfaces at the second side of an opening of the edge groove.
12. The set of panels as claimed in any one of claims 1 to 10, wherein the angleable locking device comprises cooperating surfaces at the second side of an opening of the edge groove at an outer edge surface at an outer comer of the panel and the adjacent panel in a locked position.
13. The set of panels as claimed in any one of claims 1 to 12, wherein the angleable locking device comprises a bottom part of the panel at a bottom of the edge groove and a side part, 84214761 16 wherein the bottom part is bendable such that the side part is displaceable for enabling said angling motion.
14. The set of panels as claimed in any one of claims 1 to 13, wherein the angleable locking device comprises a bevel or rounding at an opening of the tongue groove. 5 15. The set of panels as claimed in any one of claims 1 to 14, wherein the second edge and the edge groove comprise cooperating surfaces at the first side of the edge groove for positioning of the second edge relative the edge groove in a depth direction of the edge groove.
16. The set of panels as claimed in any one of claims 1 to 14, wherein the second edge and the edge groove comprise cooperating surfaces at the first side of the edge groove between the 10 insertion groove and a bottom surface of the edge groove, for positioning of the second edge relative the edge groove in a depth direction of the edge groove.
17. The set of panels as claimed in claim 15 or claim 16, wherein the cooperating surfaces are a first surface of a recess at the second edge and a second surface of a recess at the edge groove. Date Re^ue / Date Received 2023-09-11
