Abstract

A floor panel includes a substrate and a top layer provided on the substrate. The top layer is composed of a print and a transparent thermoplastic layer having a thickness of 0.5 mm or less and is situated above the print. The floor panel, at least on two opposite edges, is provided with a straight or curved chamfer extending to below the global level of the print.

Claims (48)

1. A floor panel comprising:

a substrate defining a thickness of 2 to 10 millimeters, and a top layer provided on the substrate, the top layer including at least a print representing a wood pattern and being provided on a PVC-based film, an underlying layer situated between the substrate and the print, and a transparent thermoplastic layer based on PVC and situated above the print, the floor panel, at least on a long pair of two opposite edges, defining a straight or curved chamfer, such that when two of said floor panel are in an installed condition said chamfers form a V-shaped groove;

wherein the transparent thermoplastic layer has a thickness of 0.15 to 0.4 millimeters and is substantially free from solid additives;

wherein the chamfer extends below the global level of said print and through said print into the underlying layer;

wherein said chamfer is provided with a separate decorative layer comprising a lacquer layer or a transfer print layer;

wherein the floor panel has a rectangular and oblong shape;

wherein a material of the substrate is composed of glued together wood particles or MDF or HDF, the underlying layer includes a thermoplastic material extending completely above a centerline of a thickness of the panel; and

wherein the underlying layer includes a PVC layer.

2. The floor panel of claim 1 , wherein, in an installed condition of two of such floor panels, a contact surface is formed on the respective underlying layers, wherein the contact surface extends underneath a deepest point or bottom of the respective chamfers.

3. The floor panel of claim 2 , wherein said underlying layers comprise a compressed part at the location of the contact surface.

4. The floor panel of claim 1 , wherein the floor panel, at respective edges, includes mechanical coupling means for coupling two of such floor panels to each other, such that a locking is created in a vertical direction perpendicular to the plane of the coupled panels, as well as in a horizontal direction perpendicular to the coupled edges and in the plane of the panels.

5. The floor panel of claim 1 , wherein said substrate, at least at one of said edges, is waterproof.

6. The floor panel of claim 1 , wherein a width of the panel is at least 8 cm.

7. The floor panel of claim 1 , wherein a length of the panel is at least 110 cm.

8. The floor panel of claim 1 , wherein at least one layer of the floor panel has a density larger than 650 kilograms per cubic meter.

9. The floor panel of claim 1 , further comprising coupling parts in the form of a tongue and a groove are substantially provided by the material of the substrate.

10. The floor panel of claim 1 , wherein the substrate has a thickness more than half of the entire thickness of the floor panel.

11. The floor panel of claim 1 , wherein a thickness of the underlying layer is more than 45 percent of an overall thickness of the top layer.

12. The floor panel of claim 1 , wherein the chamfer extends below the global level of said print and into said substrate.

13. The floor panel of claim 1 , wherein the chamfer extends into the underlying layer and is situated completely above the substrate.

14. The floor panel of claim 1 , wherein the PVC layer of the underlying layer is a soft PVC layer that includes a plasticizer.

15. The floor panel of claim 1 , wherein the PVC layer of the underlying layer includes PVC and chalk.

16. A floor panel comprising:

a substrate defining a thickness of 2 to 10 millimeters, and a top layer provided on the substrate, the top layer being composed of at least a print representing a wood pattern and being provided on a PVC-based film, and a transparent thermoplastic layer based on PVC and situated above the print, the floor panel, at least on a long pair of two opposite edges, defining a straight or curved chamfer, such that when two of said floor panel are in an installed condition said chamfers form a V-shaped groove;

wherein the chamfer extends below the global level of said print and through said print into an underlying layer or into said substrate;

wherein said chamfer is provided with a separate decorative layer comprising a lacquer layer or a transfer print layer;

wherein the floor panel has a rectangular and oblong shape;

wherein the substrate is substantially made from a soft PVC including PVC with a plasticizer content, the panel including a glass fiber containing layer at a position under the print and embedded in the substrate material.

17. The floor panel of claim 16 , wherein the chamfer extends into the substrate and is situated completely above the glass fiber layer.

18. The floor panel of claim 16 , wherein the transparent thermoplastic layer has a thickness of 0.15 to 0.4 millimeters.

19. The floor panel of claim 16 , wherein the transparent thermoplastic layer is substantially free from solid additives.

20. The floor panel of claim 16 , wherein the floor panel, at respective edges, includes mechanical coupling means for coupling two of such floor panels to each other, such that a locking is created in a vertical direction perpendicular to the plane of the coupled panels, as well as in a horizontal direction perpendicular to the coupled edges and in the plane of the panels.

21. The floor panel of claim 16 , wherein a width of the panel is at least 8 cm.

22. The floor panel of claim 16 , wherein a length of the panel is at least 110 cm.

23. The floor panel of claim 16 , wherein at least one layer of the floor panel has a density larger than 650 kilograms per cubic meter.

24. The floor panel of claim 16 , further comprising coupling parts in the form of a tongue and a groove are substantially provided by the material of the substrate.

25. The floor panel of claim 16 , wherein the substrate has a thickness more than half of the entire thickness of the floor panel.

26. The floor panel of claim 16 , wherein the floor panel, at respective edges, includes mechanical coupling means for coupling two of such floor panels to each other, and in a coupled condition a contact zone is formed above the glass fiber layer.

27. The floor panel of claim 26 , wherein said contact zone creates a barrier against moisture penetration of a coupled joint of the two of such floor panels.

28. The floor panel of claim 16 , wherein the chamfer has an angle of 35° to 55° with a top surface of the panel.

29. A floor panel comprising:

a substrate defining a thickness of 2 to 10 millimeters, and a top layer provided on the substrate, the top layer including at least a print representing a wood pattern and being provided on a film, an underlying layer situated between the substrate and the print, and a transparent thermoplastic layer and situated above the print, the floor panel, at least on a long pair of two opposite edges, defining a straight or curved chamfer, such that when two of said floor panel are in an installed condition said chamfers form a V-shaped groove;
