Abstract

A wall or ceiling panel, which, on one side edge, comprises a male coupling part and, on an opposite side edge, comprises a female coupling part. The male coupling part comprises a tongue and the female coupling part comprises a groove. The groove is bordered by a front lip and a rear lip, with the characteristic that the panel forms a ceiling-high wall panel and/or has a length of at least 2400 mm.

First claim

The invention claimed is:

1. A wall or ceiling panel, which, on one side edge of the panel, comprises a male coupling part and, on an opposite side edge of the panel, comprises a female coupling part,
wherein the male and female coupling parts are configured such that two of such panels, by means of the male and female coupling parts, can be coupled to each other in a plane and a coupled condition can be realized between the panels;
wherein the male coupling part comprises a tongue and the female coupling part comprises a groove, wherein the tongue and the groove, in the coupled condition, form a tongue-and-groove connection, which realizes a mechanical locking between the panels in a direction perpendicular to the plane of the panels;
wherein the groove is bordered by a front lip and a rear lip;
wherein the male and female coupling parts each comprise a locking part, wherein the locking part of the male coupling part and the locking part of the female coupling part, in a coupled condition, realize a mechanical locking between the panels in a direction in the plane of the panels and perpendicular to the side edges;
wherein the panel forms a ceiling-high wall panel and/or has a length of at least 2400 mm and the panel is configured such that the rear lip, or at least a part thereof, can bend in a rearward direction, even if a rear side of the panel or the rear lip is secured to a flat substructure; and
wherein the front lip extends substantially parallel to the plane of the panels, and the rear lip of the groove extends substantially parallel to the front lip with a distal end of the rear lip extending parallel to the plane of the panels.

2. The wall or ceiling panel of claim 1 , wherein the locking part of the male coupling part is provided on the rear side of the tongue and the locking part of the female coupling part is provided on the front side of the rear lip; and
wherein the bending in rearward direction of the rear lip, or at least a part thereof, provides for a rearward moving or tilting of the locking part of the female coupling part.

3. The wall or ceiling panel of claim 1 , wherein the rear lip, at the rear side thereof, is provided with a recess which allows the aforementioned rearward bending of the rear lip or at least a part thereof.

4. The wall or ceiling panel of claim 3 , wherein the recess extends from an open or free end of the rear lip to beyond the active locking zone defined by the locking parts.

5. The wall or ceiling panel of claim 3 , wherein the panel comprises a core, and the recess is substantially formed from a material of the core from cut or milled portions of the material of the core.

6. The wall or ceiling panel of claim 1 , wherein the panel shows one or more of the following characteristics:
the rear lip extends in distal direction beyond an open or free end of the front lip;
the active locking zone defined by the locking parts is situated partially or entirely beyond the open or free end of the front lip;
the part of the rear lip which, in distal direction, extends beyond the open or free end of the front lip, is longer than a thickness of the panel;
the most proximally situated point of the recess is situated at a distance different from zero from the open or free end of the front lip;
the male and female coupling parts are of the turning type with snap or click effect;
the male and female coupling parts are configured such that they, in the coupled condition, fit into each other with pretension; and/or
the male and female coupling parts are realized entirely from the material of the panel and in one part therewith;
the panel has a width-to-length ratio smaller than 1/20 and larger than 1/60;
the panel has a water-resistant front and rear side;
the panel has a melamine layer on the front and rear sides;
the panel has a UV-hardened lacquer layer on the front and rear sides;
the panel comprises a water-tight foil on the front and rear sides, selected from the group consisting PVC (Polyvinylchloride) foil, a PET (Polyethylene terephthalate) foil, and a PP (Polypropylene) foil;
the panel comprises a material as a core which is based on a, whether or not filled, synthetic material.

7. The wall or ceiling panel of claim 1 , wherein one of the side edges is configured such that an attachment element can be provided thereon in order to secure the panel to a substructure.

8. The wall or ceiling panel of claim 7 , wherein the rear lip is configured such that an attachment element can be provided thereon.

9. The wall or ceiling panel of claim 8 , wherein the front side of the rear lip is provided with a stop surface, and through the stop surface an attachment element can be provided in the rear lip.

10. The wall or ceiling panel of claim 9 , wherein the stop surface shows one or more of the following characteristics:
the stop surface is situated partially or entirely distal from an open or free end of the front lip;
the rear lip, at the rear side thereof, is provided with a recess which allows the aforementioned rearward bending of the rear lip or at least a part thereof, the stop surface is situated partially or entirely proximal from the recess;
the stop surface is situated at a distance different from zero from the active locking zone defined by the locking parts;
the stop surface, globally seen, is oriented parallel to the plane of the panel;
the stop surface, globally seen, is oriented inclined; and/or
the stop surface is situated partially or entirely behind a level running parallel to the plane of the panel, defined by the foremost point of the locking part of the female coupling part, in particular the foremost point of the locking part on the front side of the rear lip.

11. The wall or ceiling panel of claim 9 , wherein the stop surface is provided with a recess for receiving the attachment element.

12. The wall or ceiling panel of claim 11 , wherein the recess in the stop surface shows one or more of the following characteristics:
the recess is situated partially or entirely distal from an open or free end of the front lip;
the rear lip, at the rear side thereof, is provided with a recess which allows the aforementioned rearward bending of the rear lip or at least a part thereof, the recess is situated partially or entirely proximal from the recess;
the recess is situated at a distance different from zero from the active locking zone defined by the locking parts;
the recess is situated behind a level running parallel to the plane of the panel, defined by the foremost point of the locking part of the female coupling part, such as the locking part on the front side of the rear lip; and/or
the recess is adapted such that the attachment element can be provided countersunk.

13. The wall or ceiling panel according to claim 9 , wherein the rear side of the rear lip behind or at the location of the stop surface provides a support on a substructure.

14. The wall or ceiling panel of claim 9 , wherein the stop surface is provided with an indication including a color mark that indicates where the attachment element can be provided.

15. The wall or ceiling panel of claim 1 , wherein the panel shows one or more of the following characteristics:
the male and female coupling parts are respectively situated on the long side edges;
the panel is a wall panel with a length of at least 2400 mm, at least 2500 mm or at least 2600 mm;
a thickness of the panel ranges from 5 to 15 mm;
the panel is wood-based;
the panel has a wood fiberboard as a core;
the panel has a decorative front and/or rear side;
the panel is of the DPL or HPL type; and/or
the panel
