Abstract

Floor element of the type which, at least at two opposite edges, comprises coupling means enabling two of such floor elements to cooperate with each other at the respective edges, wherein the floor element comprises at least two components, as well as entity-forming means, which, starting from the aforementioned components, can form an entity including the components, wherein said components can adopt at least two mutual positions, whether or not by means of the disruption of the entity formed by said entity-forming means.

First claim

The invention claimed is:

1. A floor panel, wherein the floor panel is rectangular and comprises a pair of opposite long sides and a pair of opposite short sides,
wherein the long sides are provided with coupling parts for mutually coupling the floor panel to a similar floor panel by an angling movement,
wherein the long side coupling parts, in a coupled condition of the floor panel with the similar floor panel, effect a locking in a first direction that is perpendicular to a plane of the coupled panels, as well as in a second direction that is in the plane of the coupled panels and perpendicular to the respective coupled sides,
wherein the long side coupling parts include a tongue, at one of the long sides, and a groove, at the other of the long sides, the groove being bordered by an upper lip and a lower lip, and the long side coupling parts further include locking parts,
wherein the locking parts comprise a first locking part at the lower lip and a second locking part at an underside of the tongue,
wherein the long side coupling parts allow the coupled panels to adopt at least two mutual orientations at the respective coupled sides, including
a first mutual orientation in which upper surfaces of the panels are situated substantially in a same plane, and
a second mutual orientation in which the upper surfaces of the panels enclose an angle (A2) and in which the panels are still locked in both said first direction and said second direction, and

wherein said second mutual orientation can be adopted up to the angle (A2) enclosed by the upper surfaces of the panels of 175 degrees or less,
wherein the panels are configured to be brought from the first mutual orientation to the second mutual orientation by a relative angling movement around the coupled sides, and
wherein the panels are configured such that
when coupled in said first mutual orientation, a pretension is provided by a bending of the lower lip, and
when in said second mutual orientation, said pretension is absent.

2. The floor panel of claim 1 , wherein, in the second mutual orientation, the angle (A2) enclosed by the upper surfaces of the panels is 170 degrees or less.

3. The floor panel of claim 1 , wherein, in the second mutual orientation, the angle (A2) enclosed by the upper surfaces of the panels is 165 degrees or less.

4. The floor panel of claim 3 , wherein the angle (A2) can be adopted over an angling-in range of 15 degrees.

5. The floor panel of claim 1 , wherein the short sides are provided with coupling parts for mutually coupling the floor panel to a second similar floor panel by a movement substantially perpendicular to the plane of the panels,
wherein the short side coupling parts, in the coupled condition of the floor panel with the second similar floor panel, effect a locking in a direction in the plane of the panels and perpendicular to the respective coupled sides, the short side coupling parts being free from locking parts which effect a locking in a direction perpendicular to the plane of the coupled panels and,
wherein the short side coupling parts comprise a male coupling part at one of the short sides, and a female coupling part at the other of the short sides.

6. The floor panel of claim 5 , wherein the floor panel has a width smaller than 16 centimeters.

7. The floor panel of claim 6 , wherein the floor panel has a width smaller than 10 centimeters.

8. The floor panel of claim 7 , wherein the floor panel has a width smaller than 8 centimeters.

9. The floor panel of claim 1 , wherein the floor panel comprises a core and a top layer, wherein the top layer comprises a printed decor.

10. The floor panel of claim 1 , wherein the first locking part includes a first locking surface having a first contacting portion, and the second locking part includes a second locking surface having a second contacting portion, and
wherein, in the first mutual orientation, the first contact portion of the first locking part directly contacts the corresponding second contacting portion of the second locking part between a lower horizontal plane and an upper horizontal plane, the lower horizontal plane and the upper horizontal plane extending in a direction parallel to the upper surface of the panels in the coupled panels.

11. The floor panel of claim 10 , wherein, in the second mutual orientation, the first locking surface is free from contact with the second locking surface.

12. The floor panel of claim 1 , wherein, in the second mutual orientation, the first contact portion is entirely above said upper horizontal plane.

13. The floor panel of claim 1 , wherein the first locking part includes a first locking surface having a first contacting portion, and the second locking part includes a second locking surface having a second contacting portion, and
wherein, in the second mutual orientation, the first locking surface is free from contact with the second locking surface.

14. The floor panel of claim 1 , wherein the first locking part includes a first locking surface having a first contacting portion, and the second locking part includes a second locking surface having a second contacting portion, and
wherein, in the second mutual orientation, a clearance is provided between the first locking surface and the second locking surface such that movement of the floor panel with respect to the similar floor panel is provided in a limited distance in a direction parallel to the upper surface of the floor panel while locking in both the first direction and the second direction is maintained.

15. The floor panel of claim 1 , wherein the angle (A2) enclosed by the upper surfaces of the panels in the second mutual orientation in which the panels are still locked in both said first direction and second direction can be adopted over an angling-in range of 5 degrees.

16. The floor panel of claim 1 , wherein the angle (A2) enclosed by the upper surfaces of the panels in the second mutual orientation in which the panels are still locked in both said first direction and second direction can be adopted over an angling-in range of 10 degrees.

17. The floor panel of claim 1 , wherein the angle (A2) enclosed by the upper surfaces of the panels in the second mutual orientation in which the panels are still locked in both said first direction and second direction can be adopted over an angling-in range of 15 degrees.

18. The floor panel of claim 1 , wherein the angle (A2) enclosed by the upper surfaces of the panels in the second mutual orientation in which the panels are still locked in both said first direction and second direction can be adopted over an angling-in range of at least 15 degrees.
