Abstract

Floorboards with a surface of flexible fibers for laying a mechanically joined floating floor, and methods for manufacturing and providing floorings containing such floorboards. For example, floorboards including a surface layer and a core, for making a floating flooring, which floorboards are mechanically lockable and which along their edge portions have pairs of opposing connectors for locking similar, adjoining floorboards to each other both vertically and horizontally, wherein the surface layer comprises flexible resilient fibers.

First claim

The invention claimed is:

1. Floorboards configured to make a floating floor, the floorboards comprising a surface layer and a core, the floorboards are mechanically lockable and which along edge portions of the floorboards have pairs of opposing connectors configured for locking similar, adjoining ones of the floorboards to each other both vertically and horizontally, wherein the surface layer comprises flexible resilient fibers, and wherein a thickness of the surface layer is equal or larger than 0.5 times a thickness of the core.

2. The floorboards as claimed in claim 1 , wherein the core is made of plastic.

3. The floorboards as claimed in claim 1 , wherein the surface layer has a thickness of 1-2 mm.

4. The floorboards as claimed in claim 1 , wherein the core has a thickness of 3-5 mm.

5. The floorboards as claimed in claim 1 , wherein the connectors comprise a groove and a tongue configured for vertical locking.

6. The floorboards as claimed in claim 5 , wherein the tongue and the groove have a vertical thickness which is larger or equal than 0.5 times the thickness of the core.

7. The floorboards as claimed in claim 1 , wherein the connectors comprise a strip, a locking element and a locking groove configured for horizontal locking.

8. The floorboards as claimed in claim 7 , wherein the locking element has a horizontal extent about 0.5 times the thickness of the core.

9. The floorboards as claimed in claim 1 , wherein the floorboards are rectangular or square and wherein two opposite sides can be joined by inward angling, whereby upper adjoining joint edge portions are in contact with each other.

10. The floorboards as claimed in claim 9 , wherein the upper adjoining joint edge portions of the floorboards are compressible and are configured to be changed in shape in connection with joining.

11. The floorboards as claimed in claim 1 , wherein upper joint edges of the surface layer have a beveled portion.

12. The floorboards according to claim 1 , wherein the flexible resilient fibers are made of synthetic fibers.

13. The floorboards according to claim 1 , wherein the flexible resilient fibers are made of natural fibers.

14. The floorboards as claimed in claim 1 , wherein the surface layer is made of needle felt.

15. The floorboards as claimed in claim 1 , wherein the surface layer consists of flexible resilient fibers.

16. The floorboards as claimed in claim 1 , wherein the surface layer is glued to the core.

17. The floorboards as claimed in claim 1 , wherein the surface layer has a density below 400 kg/m3.

18. The floorboards as claimed in claim 1 , wherein the surface layer has outer joint edges projecting beyond the outer parts of the core.

19. The floorboards as claimed in claim 1 , the floorboards further comprising a balancing layer, wherein the balancing layer is arranged on a rear side of the core opposite the surface layer.

20. The floorboards as claimed in claim 19 , wherein the balancing layer comprises foam, needle felt, or cardboard.
