Abstract

Claims (23)

1 . A floor panel, wherein said floor panel is rectangular and comprises a first and a second pair of opposite edges, and an upper surface, wherein the upper surface consists of a global decorative side and at least a chamfer on one of the first and second pair of opposite edges;

wherein said floor panel comprises a substrate and a top layer provided on said substrate; said top layer forming at least said global decorative side of said floor panel and being composed at least of a synthetic material film carrying a print, a transparent thermoplastic layer situated above said print and a lacquer layer as a topmost layer in said top layer, wherein the synthetic material film is a PVC-based film, wherein a common thickness composing the synthetic material film, said print, said transparent thermoplastic layer and said lacquer layer is between 0.5 and 2 millimeters;

said substrate being a board material having a density of more than 650 kilograms per cubic meter and forming at least one half of a thickness of said floor panel; said substrate being a vinyl-containing and/or polyethylene-containing substrate;

wherein said print, at said global decorative side, has a global level within the top layer and extends downward at the chamfer, wherein said chamfer is straight or curved, and is adjacent to said global decorative side, said chamfer extending below the global level of the print;

wherein said print and said lacquer layer extend uninterruptedly from on the global decorative side of the floor panel over an entirety of said chamfer;

wherein said top layer, including the synthetic material film, the print, the transparent thermoplastic layer and the lacquer layer, extends over the chamfer and comprises a pressed-down material part at said chamfer and said substrate at a location of said chamfer comprises a locally compressed portion.

2 . The floor panel of claim 1 , wherein the floor panel is provided with mechanical coupling means located at least one of said first and second pair of opposite edges, and allowing to couple two of such floor panels to each other, such that a locking is created in a vertical direction perpendicular to a plane of the coupled panels, and in a horizontal direction perpendicular to the coupled edges and in the plane of the panels.

3 . The floor panel of claim 2 , wherein said floor panel is rectangular and oblong with said first pair of opposite edges forming a longer pair of opposite edges, and wherein said chamfer is at least provided on said first pair of opposite edges.

4 . The floor panel of claim 3 , wherein said transparent thermoplastic layer has a thickness of 0.5 millimeters or less.

5 . The floor panel of claim 3 , wherein said chamfer inclines or curves downward from said global decorative surface towards a deepest point on a surface of the chamfer with respect to the global decorative side of the floor panel, wherein said floor panel comprises a lateral edge extending from said deepest point and perpendicular to said global decorative side.

6 . The floor panel of claim 3 , wherein said chamfer inclines or curves downward from said global decorative surface towards a deepest point on a surface of the chamfer with respect to the global decorative side of the floor panel, wherein, in an installed condition of two of such floor panels, a contact surface is formed extending underneath the deepest point or bottom of the respective chamfers.

7 . The floor panel of claim 3 , wherein said transparent thermoplastic layer comprises PVC and 5 to 75 percent by weight of plasticizer.

8 . A floor panel, wherein said floor panel is rectangular and comprises a first and a second pair of opposite edges, and an upper surface, wherein the upper surface consists of a global decorative side and at least a chamfer on one of the first and second pair of opposite edges;

wherein said floor panel comprises a substrate and a top layer provided on said substrate; said top layer forming at least said global decorative side of said floor panel and being composed at least of a synthetic material film carrying a print, a transparent thermoplastic layer situated above said print and a lacquer layer as a topmost layer in said top layer, wherein the synthetic material film is a PU-based or PP-based film, wherein a common thickness composing the synthetic material film, said print, said transparent thermoplastic layer and said lacquer layer is between 0.5 and 2 millimeters;

said substrate being a board material having a density of more than 650 kilograms per cubic meter and forming at least one half of a thickness of said floor panel; said substrate being a polypropylene-containing and/or polyethylene-containing substrate;

wherein said print, at said global decorative side, has a global level within the top layer and extends downward at the chamfer, wherein said chamfer is straight or curved, and is adjacent to said global decorative side, said chamfer extending below the global level of the print;

wherein said print and said lacquer layer extend uninterruptedly from on the global decorative side of the floor panel over an entirety of said chamfer;

wherein said top layer, including the synthetic material film, the print, the transparent thermoplastic layer and the lacquer layer, extends over the chamfer and comprises a pressed-down material part at said chamfer and said substrate at a location of said chamfer comprises a locally compressed portion.

9 . The floor panel of claim 8 , wherein the floor panel is provided with mechanical coupling means located at least one of said first and second pair of opposite edges, and allowing to couple two of such floor panels to each other, such that a locking is created in a vertical direction perpendicular to a plane of the coupled panels, and in a horizontal direction perpendicular to the coupled edges and in the plane of the panels.

10 . The floor panel of claim 9 , wherein said floor panel is rectangular and oblong with said first pair of opposite edges forming a longer pair of opposite edges, and wherein said chamfer is at least provided on said first pair of opposite edges.

11 . The floor panel of claim 10 , wherein said transparent thermoplastic layer has a thickness of 0.5 millimeters or less.

12 . The floor panel of claim 10 , wherein said chamfer inclines or curves downward from said global decorative surface towards a deepest point on a surface of the chamfer with respect to the global decorative side of the floor panel, wherein said floor panel comprises a lateral edge extending from said deepest point and perpendicular to said global decorative side.

13 . The floor panel of claim 10 , wherein said chamfer inclines or curves downward from said global decorative surface towards a deepest point on a surface of the chamfer with respect to the global decorative side of the floor panel, wherein, in an installed condition of two of such floor panels, a contact surface is formed extending underneath the deepest point or bottom of the respective chamfers.
