Resilient groove
A set of moisture proof floorboards and a flooring of such floorboards with a resilient surface layer provided with a decorative groove and/or 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 connecting device arranged at least at two opposite edges for connecting a floorboard with another floorboard in a horizontal direction and a resilient surface layer defining the front face,
the moisture proof floorboard being provided, at an edge and completely within the resilient surface layer, with a sealing device configured to cooperate with another sealing device in the resilient surface layer at an edge of another adjacent floorboard, to obtain a sealing,
wherein one of the sealing devices is a vertically extending protrusion and the other sealing device is a vertically open groove,
wherein the core includes the connecting device, and
wherein at least a portion of the edge of the resilient surface layer including the sealing device and at least a portion of the edge of the core including the connecting device are in the same vertical plane.
2. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein one or both of the sealing devices are provided with a sealing agent.
3. The set of essentially identical moisture proof floorboards as claimed in claim 2 , wherein the sealing agent comprises paraffin wax or paraffin oil.
4. The set of essentially identical moisture proof floorboards as claimed in claim 2 , wherein the sealing agent is expandable.
5. The set of essentially identical moisture proof floorboards as claimed in claim 4 , wherein the sealing agent is expandable in contact with water.
6. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein in the connecting devices are configured for connecting a floorboard with another floorboard in a vertical direction by vertical folding.
7. The set of essentially identical moisture proof floorboards as claimed in claim 6 , wherein the connecting devices comprises a displaceable tongue configured to cooperate with a tongue groove for vertical connection.
8. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein at least one edge of each of the floorboards comprises a decorative groove in the resilient surface layer with a bottom which is essentially parallel to the front face.
9. A moisture proof flooring comprising a set of floorboards in accordance with claim 1 , wherein at least two floorboards are mechanically connected together.
10. The moisture proof flooring as claimed in claim 9 , wherein at least two floorboards are mechanically connected in the horizontal and vertical direction at adjacent edges.
11. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the connecting device comprises a locking system formed in the core.
12. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the core has a thickness in a vertical plane, the thickness of the core being greater than a thickness of the resilient surface layer.
13. The set of essentially identical moisture proof floorboards as claimed in claim 1 , wherein the sealing device is disposed proximal the front face, and the connecting device is disposed along the edge of the moisture proof floorboard between the sealing device and the rear face.
