Set of floorboards with sealing arrangement
A set of moisture proof floorboards and a flooring of such floorboards with a resilient surface layer provided with a sealing means.
1. A set of essentially identical moisture proof floorboards each 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 a floorboard with another floorboard in a vertical and/or horizontal direction and a resilient surface layer,
wherein the resilient surface layer at each of said opposite edges is provided with a sealing arrangement configured to cooperate with another sealing arrangement in the resilient layer at an edge of another floorboard, to obtain a sealing,
one of the sealing arrangements is a horizontally extending protrusion and the other sealing arrangement is a sideways open groove, one or both of the sealing arrangements being provided with a sealing agent,
wherein the horizontally extending protrusion has a top surface and a bottom surface, at least one of which is parallel to the front face of the floorboards, and the sideways open groove has a top surface and a bottom surface, a corresponding one of which is parallel to the front face of the floorboards.
2. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the sealing agent comprises paraffin wax and/or paraffin oil.
3. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the sealing agent is expandable.
4. The set of essentially identical moisture proof floorboards as claimed in claim 3 , wherein the sealing agent is expandable in contact with water.
5. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the floorboards comprise a core of a wood-based material.
6. The set of essentially identical moisture proof floorboards as claimed in claim 5 , wherein the core comprises a material selected from HDF, MDF, particleboard or plywood.
7. The set of essentially identical moisture proof floorboards as claimed in claim 6 , wherein the connector is a mechanical locking system.
8. The set of essentially identical moisture proof floorboards as claimed in claim 7 , wherein the mechanical locking system is formed in the edge of the floorboard.
9. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a plastic material.
10. The set of essentially identical moisture proof floorboards as claimed in claim 9 , wherein the plastic is PVC or polyethylene.
11. The set of essentially identical moisture proof floorboards as claimed in claim 10 , wherein the resilient surface layer comprises a transparent wear layer of a moisture proof material.
12. The set of essentially identical moisture proof floorboards as claimed in claim 11 , wherein the resilient surface layer comprises a decorative layer.
13. The set of essentially identical moisture proof floorboards as claimed in claim 12 , wherein the decorative layer is a plastic film, a wood veneer, a cork layer or a print.
14. The set of essentially identical moisture proof floorboards as claimed in claim 12 , wherein the resilient surface layer comprises a reinforcement layer closest to the core of the floorboard.
15. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer is substantially only one layer of a moisture proof material.
16. The set of essentially identical moisture proof floorboards as claimed in claim 11 , wherein the moisture proof material is plastic or rubber.
17. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer is substantially only one layer plastic or rubber.
18. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer comprises a transparent wear layer, a decorative layer and an elastic reinforcement layer, wherein the sealing arrangements are in the elastic reinforcement layer.
19. The set of essentially identical moisture proof floorboards as claimed in claim 1 , the sealing agent is provided on at least one of the top surface and the bottom surface of at least one of the horizontally extending protrusion and the sideways open groove.
20. The set of essentially identical moisture proof floorboards as claimed in claim 1 , the sealing agent is provided on the top surface and the bottom surface of at least one of the horizontally extending protrusion and the sideways open groove.
21. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the resilient surface layer is formed of only one layer of material.
