Abstract

A floor panel ( 10, 100 ) with an average density of between 1.5 and 2.5 g/cm 3 and a mass per unit area (EN ISO 23997) of between 3.5 and 8 kg/m 2 , includes at least one soft elastic core layer ( 12 ) made from a PU material and a non-slip backing ( 22 ) having an embossing, with the lateral edges of the floor panel ( 10, 100 ) being contrived such that two adjacently installed floor panels ( 10, 100 ) abut against each other along their lateral edges in a non-locking manner.

Claims (29)

1. A floor panel comprising:

an average density of between 1.5 and 2.5 g/cm3 and a mass per unit area (EN ISO 23997) of between 3.5 and 8 kg/m2,

at least one soft elastic, compressible core layer made from a polyurethane material,

a non-slip backing with an embossing, and

lateral edges of the floor panel being contrived such that two adjacently installed floor panels abut against each other along their lateral edges in a non-locking manner,

wherein the floor panel has, along its lateral edges, at least one lateral abutting surface for forming an abutting connection with an adjacently installed floor panel,

wherein the at least one lateral abutting surface includes:

a vertically oriented planar surface for abutting against a vertically oriented planar surface of an adjacent floor panel,

a chamfer on a top side of the floor panel positioned above the vertically oriented planar surface such that the chamfers at upper ends of two of the lateral abutting surfaces of adjacent floor panels form a triangular-shaped recess at the top side of the floor panel, and

a chamfer on a bottom side of the floor panel positioned below the vertically oriented planar surface such that the chamfers at lower ends of two of the lateral abutting surfaces of adjacent floor panel form a triangular-shaped recess at the bottom side of the floor panel, and

wherein the floor panel has, along its lateral edges, tongue-and-groove profiles contrived in such a way that grooves and tongues on opposite lateral edges of adjacently installed floor panels are adapted to be horizontally pushed into each other in a non-locking manner, and

wherein the grooves and tongues of the tongue-and-groove profiles each have an approximately trapezoidal cross-section with beveled flanks.

2. A floor panel according to claim 1 :

further comprising an elastic backing layer made from a polyurethane material and disposed beneath the core layer, and

wherein the backing is formed by an underside of the elastic backing layer.

3. A floor panel according to claim 1 , wherein the backing is formed by an underside of the core layer.

4. A floor panel according to claim 1 , wherein the embossing has one of:

a honeycomb structure and

a pyramid structure.

5. A floor panel according to claim 1 , wherein the chamfer on the bottom side of the floor panel is bigger than the chamfer on the top side of the floor panel.

6. A floor panel according to claim 1 , wherein at least the core layer contains fillers in order to increase the weight thereof.

7. A floor panel according to claim 1 , further comprising a glass-fiber mat which lies one of:

on top of, and

in,

the core layer.

8. A floor panel according to claim 1 , further comprising a decorative layer and a transparent utility layer covering the decorative layer.

9. A floor panel according to claim 1 , further comprising a textile layer forming a top side of the floor panel.

10. A floor panel according to claim 1 , wherein the backing has a residual indentation pursuant to EN ISO 24343 of less than 0.1 mm.

11. A floor panel according to claim 1 , wherein the floor panel has a Shore A hardness of 50 to 90.
