Abstract

The invention relates to a set of panels, in particular floor panels, comprising a first panel and at least a second panel. The panels are respectively provided with a first edge and with a second edge, wherein the first edge and the second edge are configured to establish a connection between the first and the second panel. The first edge can have a lower lip with a step, and the second edge can have a downwardly open locking groove. A separate clip can be provided which can be attached to the first edge or the second edge and has a moveable clip head, which in the connected state of the panels can cooperate with a locking surface on the second edge or the first edge, respectively, in order to lock the panels vertically relative to the plane of laying.

Claims (25)

1. A set of floor panels, said set of floor panels comprising a first panel and at least a second panel;

wherein the first panel comprises a first edge;

wherein the second panel comprises a second edge, the first edge and the second edge configured to establish a connection between the first and second panel;

wherein the first edge has a distally protruding lower lip;

wherein said first edge and second edge comprise horizontally active locking surfaces that in a connected condition of the panels cooperate with each other to thereby provide a locking in a direction in a plane of the floor panels and perpendicular to the first and second edges, the horizontally active locking surface of the first edge being located at said distally protruding lower lip, whereas the horizontally active locking surface of the second edge is provided at a lower side of the second panel;

wherein said second edge is adapted to connect with the first edge via a relative vertical movement between the first and the second panels;

wherein a separate deformable clip is disposed in a groove in the first edge, said clip having a moveable clip head which in the connected state of the panels cooperates with a vertically active locking surface at the second edge, thereby locking the panels in a direction perpendicular to the plane of the panels;

wherein the moveable clip head, considered in a cross-section, is elastically moveable between at least an initial position wherein the moveable clip is in a free condition and an assembly position in which the clip is maximally deformed during connecting the panels;

wherein said groove in which said separate clip is provided has an upper groove wall and a lower groove wall;

wherein said upper groove wall and lower groove wall are substantially parallel to each other and include an angle in respect to the plane of the connected floor panels, the groove thereby forming an inclined seat for the clip;

wherein the clip is fastened into the groove by a fastening area;

wherein said fastening area by a clamping action via fastening surfaces cooperates with the inclined walls of said groove; and

wherein the clip head does not protrude beyond an imaginary extension of the lower groove wall in the initial position.

2. The set of floor panels of claim 1 , wherein said clip at said fastening area, when viewed in cross-section perpendicular to a length direction of the first edge, comprises one or more local fastening surfaces.

3. The set of floor panels of claim 2 , wherein said one or more local fastening surfaces, seen in said cross-section, are configured as rounded protrusions.

4. The set of floor panels of claim 2 , wherein the clip is configured such that at least one of said fastening surfaces and a moveable distal portion of the clip head are present in one single cross-section perpendicular to the length of the first edge.

5. The set of floor panels of claim 3 , wherein the clip is configured such that at least one of said fastening surfaces and a moveable distal portion of the clip head are present in one single cross-section perpendicular to the length of the first edge.

6. The set of floor panels of claim 1 , wherein the clip is configured such that at least one of said fastening surfaces and a moveable distal portion of the clip head are present in one single cross-section perpendicular to the length of the first edge.

7. The set of floor panels of claim 1 , wherein the moveable clip head can adopt at least three positions, namely the initial position, the assembly position, and a locking position, wherein said locking position being the position in the connected condition of the panels and being located in between the initial position and the assembly position.

8. The set of floor panels of claim 7 , wherein the clip head in said locking position exerts a force on the vertically active locking surface which urges the second edge of the second panel against the first edge of the first panel.

9. The set of floor panels of claim 1 , wherein the fastening area has four fastening surfaces spaced apart from one another, of which two engage the upper inclined groove wall and the other two engage the lower inclined groove wall.

10. The set of floor panels of claim 1 , wherein the clip head is pivotable.

11. The set of floor panels of claim 10 , wherein the clip comprises a substantially uniform body thickness with the exception of a constricted portion defining a pivot point for the clip head.

12. The set of floor panels of claim 1 , wherein said horizontally active locking surfaces are inclined in respect to the plane of the floor panels, and wherein said vertically active locking surface of the second edge is inclined at approximately 45 degrees.

13. The set of floor panels of claim 12 , wherein said horizontally active locking surfaces have an inclination that is steeper than the inclination of the vertically active locking surface of the second edge.
