Abstract

Floor panels ( 2 ) are shown with a discontinuous surface ( 31 ) layer and core ( 30 ), which are mechanically connectable to each other along one pair of adjacent edges, said floor panels comprising at least two floor elements ( 1, 1 ′), which are connected with glue.

Claims (27)

1. A flooring system, comprising a plurality of floor panels, each of the floor panels comprises at least two connected floor elements, such that each floor panel has a discontinuous core having a core joint and a discontinuous surface layer having a surface joint,

said floor panels are mechanically connectable to each other along one pair of adjacent edges with a mechanical locking system adapted to mechanically lock the panels in the horizontal and vertical directions,

the floor elements are factory connected to each other with a tongue and groove joint and glue and the surface joint is adjacent to the core joint.

2. The flooring system as claimed in claim 1 , wherein at least one of the floor elements comprises a surface layer which is a printed layer.

3. The flooring system as claimed in claim 2 , wherein at least one of the floor elements comprises a surface layer of laminate.

4. The flooring system as claimed in claim 1 , wherein the floor elements comprise at least two pairs of adjacent edges which are glued together with a moisture-proof glue.

5. The flooring system as claimed in claim 1 , wherein each of the floor panels comprises floor elements of different sizes.

6. The flooring system as claimed in claim 1 , wherein the floor panel comprises at least three floor elements and at least two floor elements are of different sizes.

7. The flooring system as claimed claim 1 , wherein adjacent floor panels have one pair of adjacent edges which are provided with an angling locking system, where an edge of a first floor panel is pressed against an upper part of an edge of a second floor panel and the first floor panel is angled down.

8. The flooring system as claimed in claim 7 , wherein the adjacent floor panels have a second pair of adjacent edges which are provided with a vertical folding locking system.

9. The flooring system as claimed in claim 7 , wherein the adjacent floor panels have at least one edge with a separate flexible tongue, wherein the flexible tongue has an inner part mounted in an open groove in the edge and a protruding part, wherein at least a part of the flexible tongue is resiliently displaceable in the open groove.

10. The flooring system as claimed in claim 7 , wherein the adjacent floor panels have one pair of adjacent edges which is provided with a horizontal snapping or vertical folding system.

11. The flooring system as claimed in claim 1 , wherein the surface layer comprises at least two different materials, such that the surface layer of one floor element comprises a different material than the surface layer of a second floor element.

12. The flooring system as claimed in claim 11 , wherein one of the different materials is wood.

13. The flooring system as claimed in claim 11 , wherein one of the materials is a laminate layer.

14. The flooring system as claimed in claim 1 , wherein the surface layer is a thermoplastic material.

15. The flooring system as claimed in claim 1 , wherein the surface layer is wood.

16. The flooring system as claimed in claim 1 , wherein the core is made of a wood fiber based sheet.

17. The flooring system as claimed in claim 1 , wherein the core is made of High Density Fibreboard.

18. The flooring system as claimed in claim 1 , wherein the floor panel comprises an underlay material and the floor elements are glued to the underlay material.

19. The flooring system as claimed in claim 1 , wherein the connected floor elements constitute a visible pattern on an upper surface of the floor panel.

20. The flooring system as claimed in claim 1 , wherein the floor panels are identical.

21. The flooring system as claimed in claim 1 , wherein the adjacent floor panels have at least one edge with a separate flexible tongue, wherein the flexible tongue has an inner part mounted in an open groove in the edge and a protruding part, wherein at least a part of the flexible tongue is resiliently displaceable in the open groove.

22. The flooring system as claimed in claim 1 , wherein the adjacent floor panels have one pair of adjacent edges which is provided with a horizontal snapping or vertical folding system.

23. A flooring system comprising a plurality of floor panels, each of the floor panels comprises at least two floor elements factory connected to each other via a tongue and groove joint and glue, such that each floor panel has a discontinuous core having a core joint and a discontinuous surface layer having a surface joint, said floor panels are mechanically connectable to each other along one pair of adjacent edges with a mechanical locking system adapted to mechanically lock the panels in the horizontal and vertical directions, wherein at least two floor elements have a decorative groove on at least one edge and at least two decorative grooves meet each other in a T shaped pattern spaced from the panel edge.

24. A flooring system comprising a plurality of floor panels, each of the floor panels comprises at least two floor elements each shaped as a parallelogram and a third floor element shaped as quadratic panel, the floor elements factory connected to each other via a tongue and groove joint and glue, such that each floor panel has a discontinuous core having a core joint and a discontinuous surface layer having a surface joint, said floor panels are mechanically connectable to each other along one pair of adjacent edges with a mechanical locking system adapted to mechanically lock the panels in the horizontal and vertical directions.

25. A flooring system comprising a plurality of floor panels, each of the floor panels comprises at least two floor elements each shaped as a parallelogram and factory connected to each other via a tongue and groove joint and glue, such that each floor panel has a discontinuous core having a core joint and a discontinuous surface layer having a surface joint, said floor panels are mechanically connectable to each other along one pair of adjacent edges with a mechanical locking system adapted to mechanically lock the panels in the horizontal and vertical directions, wherein the two factory connected floor elements form ⅙ of a center of a star shaped pattern.
