Abstract

A set of essentially identical floorboards each including a front face and a rear face extending in the horizontal plane, a core, and a surface layer, a mechanical locking system is arranged at least at two opposite edges for connecting a floorboard with an adjacent floorboard in a horizontal and a vertical direction, said mechanical locking system being configured for connecting the floorboard with the adjacent floorboard by vertical folding, wherein one of said opposite edges is provided with a horizontally extending protrusion at an upper edge, and wherein said protrusion is configured to overlap a surface groove at an upper edge of the other of said opposite edges, such that two connected and adjacent floorboards have upper overlapping edges.

First claim

The invention claimed is:

1. A set of essentially identical moisture proof floorboards, each floorboard comprising a front face and a rear face extending in the horizontal plane, a core, a connector arranged at least at two opposite edges for connecting one of the floorboards with another floorboard in a vertical and/or horizontal direction, and a resilient surface layer,
wherein at least one edge of each of the floorboards comprises a decorative edge part in the resilient surface layer,
wherein the decorative edge part is a cut area in the resilient surface layer,
wherein a width of the cut area is greater than a thickness of the resilient layer,
wherein the decorative edge part has a roughness and a brightness that differ from a roughness and a brightness of the remaining front face,
and wherein the at least one edge, which comprises the decorative edge part, comprises a sealing arrangement in the resilient layer wherein said sealing arrangement is configured to cooperate with another sealing arrangement in the resilient layer at an edge of another adjacent floorboard to obtain a sealing.

2. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein one of the sealing arrangements is a horizontally extending protrusion and the other sealing arrangement is a sideways open groove having an upper surface and an opposing lower surface that extend parallel with the horizontal direction.

3. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein one or both of the sealing arrangements comprises a sealing agent.

4. The set of essentially identical moisture proof floorboards as claimed in claim 3 , wherein the sealing agent comprises paraffin wax or paraffin oil.

5. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein both of the sealing arrangements are a sideways open groove being provided with a sealing agent.

6. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein each floorboard is provided with the decorative edge part only at one of two opposite edges.

7. The set of essentially identical moisture proof floorboards as claimed in claim 6 , wherein each floorboard is quadrilateral and has a decorative joint portion only at one of two opposite edges.

8. The set of essentially identical moisture proof floorboards as claimed in claim 6 , wherein each floorboard is quadrilateral and has a decorative joint portion only at two adjacent edges.

9. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein each floorboard comprises a core of a wood-based material.

10. The set of essentially identical moisture proof floorboards as claimed in claim 9 , wherein the core comprises HDF, MDF, particleboard or plywood.

11. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the connector is a mechanical locking system.

12. The set of essentially identical moisture proof floorboards as claimed in claim 11 , wherein the mechanical locking system is formed in the at least two opposite edges of each floorboard.

13. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a plastic material.

14. The set of essentially identical moisture proof floorboards as claimed in claim 13 , wherein the plastic material is PVC or polyethylene.

15. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a transparent wear layer of a moisture proof material.

16. The set of essentially identical moisture proof floorboards as claimed in claim 15 , wherein the bottom of the decorative edge part is in the transparent wear layer.

17. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a decorative layer.

18. The set of essentially identical moisture proof floorboards as claimed in claim 17 , wherein the decorative layer is a plastic film, a wood veneer, a cork layer or a print.

19. The set of essentially identical moisture proof floorboards as claimed in claim 17 , wherein a bottom of the decorative edge part is in the decorative layer.

20. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a reinforcement layer, and wherein the reinforcement layer is the layer of the resilient surface layer positioned closest to the core of each floorboard.

21. The set of essentially identical moisture proof floorboards as claimed in claim 20 , wherein a bottom of the decorative edge part is in the reinforcement layer.

22. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer is substantially of only one layer of a moisture proof material.

23. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the decorative edge part is at the at least two opposite edges of the floorboards at which the connector is arranged.
