Abstract

A panel for forming a covering, more particularly a floor panel for forming a floor covering, which at least at two opposite edges, comprises coupling parts arranged to couple two of such panels to each other by means of a downward movement of one panel in respect to the other. The coupling parts form a first locking system arranged to lock in the plane of the panels and perpendicularly to the edges, as well as form a second locking system, which effects a locking perpendicularly to the plane of the panels. At least one of the coupling parts is formed at least partially in soft PVC (polyvinyl chloride), as well as at least partially formed from a milled profiled part of this soft PVC.

First claim

The invention claimed is:

1. A floor panel, for forming a floor covering, said floor panel being of the type comprising a substrate of a material on the basis of soft PVC;
wherein the panel is rectangular, either oblong or square, and thus comprises a first pair of opposite edges and a second pair of opposite edges;
wherein both pairs of opposite edges comprise coupling parts allowing to mutually couple a plurality of the panels to each other;
wherein the coupling parts at both pairs of edges form a first locking system which effects a locking in the plane of the panels and perpendicular to the respective edges, as well as form a second locking system which effects a locking perpendicular to the plane of the panels;
wherein the coupling parts at the first pair of opposite edges are configured such that two of the panels can be coupled to each other at the edges by means of a turning movement
wherein the coupling parts at the second pair of edges are formed by coupling parts which are of the type allowing to couple two of the panels to each other by means of a downward movement of one panel in respect to the other;
wherein the coupling parts at both pairs of edges substantially are realized from said substrate and thus from said material on the basis of soft PVC;
wherein the first locking system of the coupling parts at the second pair of edges is formed at least of an upwardly directed lower hook-shaped portion which is situated at one of the edges of the second pair of edges, as well as of a downwardly directed upper hook-shaped portion which is situated at the opposite edge, said hook-shaped portions extending laterally from a core portion of the panel;
wherein the lower hook-shaped portion consists of a lip with an upwardly directed locking element, wherein the upper hook-shaped portion consists of a lip with a downwardly directed locking element;
wherein the lip of the upper hook-shaped portion comprises a part which connects said core portion of the panel with the downwardly directed locking element, said part, seen in a cross section perpendicular to the respective edge, defining a length; and
wherein said part, seen in said cross-section perpendicular to the respective edge, has a thickness that decreases towards the downwardly directed locking element for at least part of said length.

2. The floor panel of claim 1 , wherein said part, seen in said cross-section perpendicular to the respective edge, decreases in thickness for the majority of the length of the part.

3. The floor panel of claim 1 , wherein the coupling parts at the second pair of opposite edges are configured such that two of such floor panels can be coupled to each other by means of the downward movement obtained as a result of the turning movement at the first pair of edges.

4. The floor panel of claim 1 , wherein at least said upper hook-shaped portion is bendable in respect to the plane of the respective panel, such that the downwardly directed locking element can perform a movement, including a tilting movement, which facilitates coupling the panels.

5. The floor panel of claim 4 , wherein the coupling parts at the second pair of edges are configured such that, when coupling two of the panels at the respective edges, the downwardly directed locking element must be brought through an opening between the upwardly directed locking element and a locking part of the second locking system and wherein the downwardly directed locking element and said opening are configured such that the downwardly directed locking element fits more smoothly through said opening when at least said upper hook-shaped portion is bent, compared to the case when none of both hook-shaped portions is bent.

6. The floor panel of claim 1 , wherein said part connecting said core portion of the panel with the downwardly directed locking element, comprises a lower side, a major part of which runs upwardly inclined towards said downwardly directed locking element; and wherein said upwardly directed locking element comprises an upper side, at least a part of which is similarly inclined to the upwardly inclined part of said lower side.

7. The floor panel of claim 1 , wherein the coupling parts of the second pair of edges comprise locking parts for vertical locking which are situated next to the proximal end of the lower hook-shaped portion and next to the distal end of the upper hook-shaped portion, respectively; and wherein the locking parts are integrally made from the substrate.

8. The floor panel of claim 1 , wherein the panel is oblong, and thus has long edges and short edges, and wherein said first pair of opposite edges is formed by the long edges, wherein the second pair of opposite edges is formed by the short edges.

9. A floor panel for forming a floor covering,
a floor covering, comprising at least two opposite edges comprises coupling parts which allow coupling of two of the panels to each other by means of a downward movement of one panel in respect to the other;
wherein said coupling parts are realized at least partially in soft PVC;
wherein the coupling parts form a first locking system, which effects a locking in the plane of the panels and perpendicularly to said edges, as well as form a second locking system, which effects a locking perpendicularly to the plane of the panels;
wherein the first locking system is formed at least of an upwardly directed lower hook-shaped portion which is situated at one of said two edges, as well as of a downwardly directed upper hook-shaped portion which is situated at the opposite edge, said hook-shaped portions extending laterally from a core portion of the panel;
wherein the lower hook-shaped portion consists of a lip with an upwardly directed locking element, wherein the upper hook-shaped portion consists of a lip with a downwardly directed locking element;
wherein the lip of the upper hook-shaped portion comprises a part which connects said core portion of the panel with the downwardly directed locking element, said part, seen in a cross section perpendicular to the respective edge, defining a length; and
wherein said part, seen in said cross-section perpendicular to the respective edge, has a thickness that decreases towards the downwardly directed locking element for at least part of said length.

10. The floor panel of claim 9 , wherein said part, seen in said cross-section perpendicular to the respective edge, decreases in thickness for the majority of the length of the part.

11. The floor panel of claim 9 , wherein at least said upper hook-shaped portion is bendable in respect to the plane of the respective panel, such that the downwardly directed locking element can perform a movement, including a tilting movement, which facilitates coupling the panels.

12. The floor panel of claim 11 , wherein the coupling parts are configured such that, when coupling two of the panels at the respective edges, the downwardly directed locking element must be brought through an opening between the upwardly directed locking element and a locking part of the second locking system and wherein the downwardly directed locking element and said opening are configured such that the downwardly directed locking element fits more smoothly through said opening when at least said upper hook-shaped portion is bent, compared to the case when none of both hook-shaped portions is bent.

13. The floor panel of claim 9 , wherein said part connecting said core portion of the panel with the downwardly directed locking element, comprises a lower side, a major part of which runs upwardly inclined towards said downwardly directed locking element; and wherein said upwardly directed locking element com
