Abstract

A panel fastening system, especially floor panels, whose narrow sides are fitted with retaining profiles. The retaining profile of a front narrow side, the retaining profile of the opposite back narrow side, the retaining profile of a left narrow side and the retaining profile of the opposite right narrow side of a panel match each other in such a way that similar panels can be fixed to one another. The mutually matching retaining profiles have complementary hook elements that can be hooked into one another and the hook elements have retaining surfaces which hold the panels against each other when the panels are mounted in such a way that a gap-free surface is obtained.

Claims

1. A fastening system for panels comprising:

at least one pair of oppositely disposed retaining profiles arranged on each of the panels;

a first of the pair of retaining profiles arranged on a first edge of each of the panels; and

a second of the pair of retaining profiles arranged on a second edge of each of the panels, the first edge being opposite the second edge on each of the panels;

the first of the pair of retaining profiles having a first, hook element and the second of the pair of retaining profiles having a second hook element;

the first hook element complementing the second hook element such that the first hook element on a first panel hooks directly and vertically into the second hook element on a second panel to fasten the first panel to the second panel;

the first hook element having a first hook projection connected to the first edge of each of the panels by a first leg, the first leg projecting from an upper portion of the first edge of each of the panels, the first hook projection having an inclined retaining surface, such that the first hook projection is reduced from a distal end of the first hook projection to a proximal end of the first hook projection;

the second hook element having a second hook projection connected to the second edge of each of the panels by a second leg, the second leg projecting from a lower portion of the second edge of each of the panels, the second hook projection having an inclined retaining surface, such that the second hook projection is reduced from a distal end of the second hook projection to a proximal end of the second hook projection;

wherein, in a fastened position,

the inclined retaining surface of the first hook projection of the first panel bears against the inclined retaining surface of the second hook projection of the second panel to fasten the first panel against the second panel so as to afford a gap-free floor surface;

the distal end of the second hook projection of the second panel bears against the first leg of the first panel, and

a space is provided between the distal end of the first hook projection of the first panel and the second leg of the second panel, the space extending vertically between the distal end of the first hook projection of the first panel and second leg of the second panel and extending horizontally between the proximal end of the second hook projection of the second panel and the second edge of the second panel.

2. The fastening system according to claim 1, wherein the first leg projects approximately perpendicularly from the first edge of the first panel, the first hook projection projects vertically downward from a distal end of the first leg, the second leg projecting approximately perpendicularly from the second edge of the second panel, and the second hook projection projects vertically upward from a distal end of the second leg.

3. The fastening system according to claim 1, wherein each of the first and second inclined retaining surfaces engage each other such that each of the first and second hook elements hook one into the other only by elastic deformation.

4. The fastening system according to claim 3, wherein a clearance is provided between an end surface of the second hook projection of the second panel and the first edge of the first panel, and the proximal end of the first hook projection at an upper portion of the first panel bears against the second panel at least in a region of the upper portion of the second edge of the second panel.

5. The fastening system according to claim 1, wherein intermediate spaces in the fastened condition of the first and second panels form adhesive pockets.

6. The fastening system according to claim 1, wherein the panels substantially comprise an MDF, HDF, or chipboard material.

7. The fastening system according to claim 1, wherein, an inclined adhesive pocket is formed between an inwardly inclined end of the first panel and an outwardly inclined portion of the second panel, which mates with the end of the first panel at top sides of the first panel and the second panel and extends downward toward the leg of the second panel.
