Abstract

A composed element includes at least two panel-shaped elements, which each have an edge zone in which coupling means are present in a profiled part respectively extending in the longitudinal direction of the respective edge zone, and each including an end face extending transversely to the respective edge zone. The profiled parts allow the coupling of the panel-shaped elements together in an interlocking manner. At least one of the panel-shaped elements includes an arrangement which hides from view at least a portion of the profiled part formed at the pertaining edge zone at the location of the end face.

Claims (27)

1. A board, which, for a majority of its thickness, is composed of a first layer of a pressed wood composite, comprising wood components which are bonded by a binding agent;

wherein over a local thickness, the board is provided with a second layer comprising a polymer selected from a group consisting of an elastomer, a polyurethane, or a product on a basis of polyurethane;

wherein the first layer and the second layer are parallel with one another and parallel with a plane of the board;

wherein the first layer and the second layer are superimposed upon each other;

wherein the second layer comprises second wood components;

wherein in said second layer the elastomer and/or the polyurethane and/or product on the basis of polyurethane is situated between the second wood components, and/or the second wood components are impregnated with the elastomer and/or polyurethane and/or the product on the basis of polyurethane;

wherein a top layer is located on top of said second layer providing an upper side of the board;

wherein the top layer comprises a printed decor.

2. The board of claim 1 , wherein said second layer comprises thermoplastic polyurethane.

3. The board of claim 1 , wherein the wood components of the pressed wood composite comprise particles and/or wood fibers.

4. The board of claim 1 , wherein the pressed wood composite is selected from a group consisting a particle board, a wood fiberboard, a medium density fiberboard (MDF) or a high density fiberboard (HDF).

5. The board of claim 1 , wherein said polymer material acts as binding agent for the second wood components in said second layer.

6. The board of claim 1 , wherein the second wood components in said second layer comprise wood particles or wood fibers.

7. The board of claim 1 , wherein in said second layer the second wood components are glued together by said polymer; and

wherein said pressed wood composite comprises wood components glued with a binding agent with does not comprise said polymer.

8. The board of claim 1 , wherein said pressed composite comprises wood fibers bonded together by a binding agent; and

wherein said second wood components comprise wood particles, wherein said wood particles are bonded together by said polymer.

9. The board of claim 1 , wherein said second layer is situated in a proximity of a surface of the board, or wherein said second layer is situated adjacent to the surface of the board.

10. The board of claim [[ 12 ]] 1 , wherein the top layer comprises a laminate layer.

11. The board of claim 10 , wherein said laminate layer is a DPL (Direct Pressure Laminate) or a HPL (High Pressure Laminate).

12. The board of claim 1 , wherein said top layer comprises a printed decor and one or more layers of lacquer or of transparent top layers.

13. The board of claim 1 , wherein an upper side of the said second layer is not more than 2 mm beneath a surface of the board.

14. A floor panel, wherein the floor panel is provided by the board of claim 1 .

15. The floor panels of claim 14 , further comprising coupling means and locking elements for coupling a plurality of the floor panels to each other such that in coupled condition the floor panels are locked in a direction perpendicular to the surface of the floor panels and in the direction perpendicular to the coupled edges and parallel with the surface of the coupled floor panels.

16. The floor panel of claim 15 , wherein the coupling means comprise a tongue and a groove.

17. The board of claim 1 , wherein the second layer is more elastic than the top layer.

18. The board of claim 1 , wherein the second layer is directly beneath the top layer.
