Abstract

A floor panel for forming a floor covering, wherein the floor covering consists of floor panels, which, on at least one pair of edges, are provided with coupling parts. The coupling parts substantially are manufactured from the material of the floor panel, and the coupling parts are configured such that two such floor panels, at the pair of edges, can be installed and locked to each other by means of a downward movement and/or by means of the fold-down principle.

First claim

The invention claimed is:

1. A floor panel for forming a floor covering,
wherein the floor panel comprises a top, a first pair of opposite edges, and a second pair of opposite edges;
wherein the first pair of opposite edges comprises first coupling parts, which allow that two of such floor panels mutually can be coupled to each other, and wherein said first coupling parts show the following characteristics:
the first coupling parts comprise a first horizontally active locking system, which, in a coupled condition of two of such floor panels, effects a locking in a plane of the floor panels and perpendicular to the first pair of opposite edges;
the first coupling parts also comprise a vertically active locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the floor panels;
the first coupling parts substantially are realized from a material of the floor panel itself; and
the first coupling parts are configured such that two of such panels can be coupled to each other at the first pair of opposite edges by means of a turning movement;
wherein the second pair of opposite edges also comprises second coupling parts on each edge of said second pair of opposite pair of edges, which allow that two of such floor panels mutually can be coupled to each other, wherein said second coupling parts show the following characteristics:
the second coupling parts comprise a second horizontally active locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the second pair of opposite edges;
the second coupling parts also comprise a vertically active locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the floor panels;
the second coupling parts substantially are realized from the material of the floor panel itself;
the second horizontally active locking system of the second pair of edges is formed at least of an upward-directed lower hook-shaped part which is situated on one edge of said second pair of edges, and as a downward-directed upper hook-shaped part, which is situated on an opposite edge of the said pair of opposite edges, wherein the lower hook-shaped part consists of a lip with an upward-directed locking element, which proximally thereof defines a female part in the form of a recess, whereas the upper hook-shaped part consists of a lip with a downward-directed locking element forming a male part;
the second coupling parts are configured such that two of such floor panels can be coupled to each other at said respective edges of said second pair of edges by means of a downward movement of the one floor panel in respect to the other;
the second horizontally active locking system comprises second horizontally active locking parts, which by means of respective contact surfaces define at least a first contact zone;
the vertically active locking system comprises vertically active locking parts, which, by means of respective contact surfaces, define at least a second contact zone, wherein the first contact zone and the second contact zone are situated at opposite sides of the male part and female part;
the vertically active locking parts and the second horizontally active locking parts comprise a first locking part and a second locking part at the respective opposite sides of the male part, and as a third locking part and a fourth locking part at the respective opposite sides of the female part;
the first and third locking parts, in the coupled condition of two of such floor panels define said first contact zone, the first and third locking parts have contact surfaces which, in coupled condition, define at least one first tangent line;
the second and fourth locking parts, in the coupled condition of two of such floor panels, define said second contact zone, the second and fourth locking parts have contact surfaces, which, in the coupled condition, also define at least one second tangent line;
said male part has a distal side and a proximal side, wherein the second locking part is situated at the distal side;
wherein the second pair of edges also shows the following characteristic:
the two contact surfaces of the second contact zone, including extensions thereof, seen in cross-section, extend to a left and to a right of a respective closing surface, wherein the closing surface is defined as a vertical plane at a location where the coupled floor panels meet each other at the top.

2. The floor panel of claim 1 , wherein said two at least one first tangent line and said at least one second tangent line are upwardly inclined towards each other from said first and second contact zones, respectively.

3. The floor panel of claim 1 , wherein said closing surface intersects the second contact zone, including extensions thereof, halfway or approximately halfway thereof.

4. The floor panel of claim 3 , wherein in that said intersection is located at a height which is higher than a position at which an entirety of the first contact zone is situated.

5. The floor panel of claim 1 , wherein at the male part, at a height lower than the second contact zone, a contact surface is provided, which, in the coupled condition, together with a contact surface on the coupled floor panel, forms a support point which limits the movement of the male part in downward direction.

6. The floor panel of claim 5 , wherein the contact surfaces forming said support point are situated on a lower side of the male part and on an upper side of the lip of the lower hook-shaped part, respectively, wherein in coupled condition, distally from the support point a space is present between the lower side of the male part and the upper side of said lip, underneath the entire portion of the male part situated distally from said support point, wherein the space is formed in that a portion of the upper side of the lip is situated deeper than the support point, and/or wherein the space, seen in a cross-section of the respective edge, extending over a distance which is at least ⅓ of a width of the male part.

7. The floor panel of claim 1 , wherein at the lower side of the lip of the lower hook-shaped part, a recess is present, which extends up to a distal end of the lip and which allows a bending of the lip in downward direction.

8. The floor panel of claim 1 , wherein at the distal side of its distal end, the lower hook-shaped part is free from vertically active mechanical locking parts.

9. The floor panel of claim 1 , wherein the contact surfaces of the second and fourth locking part, and extensions of these surfaces, are made flat or substantially flat.

10. The floor panel of claim 1 , wherein the contact surfaces of the second and fourth locking part, and the tangent line defined thereby, form an angle with the horizontal which is larger than 70 degrees, wherein said tangent line slopes upwardly in a distal direction with respect to said lower hook-shaped part.

11. The floor panel of claim 1 , wherein the contact surfaces of the second and fourth locking part, and extensions of these surfaces, in upward direction each terminate at locations which are situated lower than the upper surface of the floor panels.

12. The floor panel of claim 1 , wherein starting from upper ends of the contact surfaces of the second and fourth locking part, and from extensions of these surfaces, up to the upper surface of the floor panel, lateral edge portions are formed, which extend more straight upward than said contact surfaces and are vertical or approximately vertical.

13. The floor panel of claim 1 , wherein at
