Abstract

A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.

First claim

What is claimed is:

1 . A floor panel comprising:
a substrate having a top side and a bottom side; and a top layer provided on the substrate; wherein the top layer consists of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film; wherein the top layer is directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer; wherein the substrate is a synthetic material board including a filler; wherein the substrate at least at two opposite edges includes coupling means provided in the synthetic material board; and wherein the thermoplastic transparent or translucent layer is provided with a structure.

2 . The floor panel of claim 1 , wherein the substrate is foamed.

3 . The floor panel of claim 2 , wherein the substrate has a locally higher density at the top side or at the bottom side as compared to the density of the substrate in a central layer.

4 . The floor panel of claim 3 , wherein the locally higher density is at least 5 percent higher than an average density of the substrate.

5 . The floor panel of claim 2 , wherein the substrate is of the closed cell type.

6 . The floor panel of claim 1 , wherein the substrate has an average density of 450 to 900 kilograms per cubic meter.

7 . The floor panel of claim 1 , wherein the top layer has a thickness of 0.5 to 3 millimeters.

8 . The floor panel of claim 1 , wherein the synthetic material board is an extruded board material.

9 . The floor panel of claim 1 , wherein the printed thermoplastic film is a printed PVC film; and
wherein the thermoplastic transparent or translucent layer includes a vinyl compound.

10 . A floor panel comprising:
a substrate having a top side and a bottom side; and a top layer provided on the substrate; wherein the top layer consists of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film; wherein the substrate is a synthetic material board including a filler; wherein the substrate at least at two opposite edges includes coupling means provided in the synthetic material board; and wherein the coupling means enable a locking with a similar floor panel at the respective edges; the locking preventing separation of the locked floor panels in a horizontal direction perpendicular to the edges using locking parts provided in each other whereby at least one pair of horizontally active locking surfaces is created, the horizontally active locking surfaces being oriented at an angle A of more than 90 degrees with the horizontal direction; the locking preventing separation of the locked floor panels in a vertical direction perpendicular to the plane of the locked floor panels.

11 . The floor panel of claim 10 , wherein the locking parts include an upstanding part at a bottom lip of a first one of the edges and a cooperating therewith recess at the bottom side of a second one of the edges.

12 . The floor panel of claim 11 , wherein the bottom lip in a locked condition is bent.

13 . The floor panel of claim 10 , wherein the locking parts are formed from the material of the substrate.

14 . The floor panel of claim 10 , wherein the coupling means allow a coupling by use of a downwardly directed movement of a second one of the edges into a first one of the edges.
