Abstract

The invention relates to a covering comprising mechanically interconnectable panels having the following characteristics: —adjacent first and second panels (1, 2) each have a groove (12, 17) on their mutually complementary sides, —in one of the grooves (12) a tongue (16) is arranged which is displaceable relative to the panel (1) and which is configured to engage in the groove (17) of the adjacent panel (2) when connecting the adjacent panels (1, 2), —the panel (1) which holds the tongue (16) has a lower locking rail (3) which engages the adjacent panel (2) underneath which is configured to secure adjacent panels (1, 2) against tensile loading in the plane of installation, —the panel (2) engaged underneath by the locking rail (3) is supported on the locking rail (3) as well as on the support rail (11) which is arranged at a greater distance to the locking rail (3) than the groove (12), —the support rail (11) engages in the same groove (17) into which the tongue (16) is displaceable.

Claims

1. A covering, comprising:

first and second panels disposed adjacent to one another and having confronting sides which complement each other, each said side having a groove; and

a tongue movably received in one of the grooves of one of the first and second panels for engagement in the groove of the other one of the first and second panels when the first and second panels are connected, wherein the one of the first and second panels has a support rail and a locking rail, said locking rail engaging underneath the other one of the first and second panels for protecting the first and second panels against a tensile force in a plane of installation, and wherein the other one of the first and second panels is supported on the locking rail in a direction perpendicular to the plane of installation and is supported on the support rail only in a direction different from the direction perpendicular to the plane of installation, said support rail being disposed at a greater distance to the locking rail than the one of the grooves of the first and second panels and engaging in the groove of the other one of the first and second panels.

2. The covering of claim 1, wherein the tongue in a locking position is at least partially bent and maintained under tension at a transition from the groove of the first panel to the groove of the second panel.

3. The covering of claim 1, wherein the support rail has a top side which is arranged at a distance to a top side of the one of the first and second panels, said distance being 10% to 35% of a total thickness of the one of the first and second panels.

4. The covering of claim 1, wherein the one of the first and second panels has an indentation which adjoins a top side of the support rail.

5. The covering of claim 1, wherein the other one of the grooves of the first and second panels has a width which at a narrowest point thereof is sized greater than 1.1 times a width of the tongue.

6. The covering of claim 1, wherein the groove of the other one of the first and second panels has a lower groove flank with a front tip which extends in a same vertical plane as a front edge of the support rail.

7. The covering of claim 1, wherein the support rail is arranged adjacent to the one of the grooves of the first and second panels.

8. The covering of claim 7, wherein the support rail has a bottom edge which forms part of an upper groove flank of the one of the grooves of the first and second panels.

9. The covering of claim 8, wherein the one of the grooves of the first and second panels has a lower groove flank which is shorter than an upper groove flank of the one of the grooves of the first and second panels.

10. The covering of claim 1, wherein the other one of the first and second panels has a lower groove flank which widens towards a mouth of the groove of said panel.

11. The covering of claim 10, wherein the lower groove flank is rounded.

12. The covering of claim 11, wherein the lower groove flank is elliptically curved.

13. The covering of claim 1, wherein the first and second panels contact one another in a region of contact of the locking rail, said region being formed as beveled surface and arranged at an angle of less than 90°

relative to the plane of installation.

14. The covering of claim 13, wherein the angle is less than 60°

.

15. The covering of claim 13, wherein the beveled surface is convex.

16. The covering of claim 15, wherein the convex beveled surface is formed by at least two sections which merge into one another, said sections having different radii.

17. A method for installing the covering of claim 1, comprising:

coupling a plurality of the first and second panels of claim 1 via the locking rails to thereby engage the panels with one another; and

locking the adjacent panels via the tongue,

wherein the confronting sides of adjacent panels are interconnectable in one of three ways,

a first way in which the further one of the panels is connected with the one of the first and second panels through horizontal shift in a plane of installation so that the further one of the panels slidingly engages via the locking rail into the locking position,

a second way in which an upper edge of the further one of the panels is placed in abutting relationship to the one of the first and second panels and the further one of the panels is pivoted about the edge and shifted into the locking position,

a third way in which the further one of the panels is placed from atop upon the locking rail of the one of the first and second panels, with the groove of the one of the first and second panels and the groove of the other one of the first and second panels being oriented parallel to one another, or positioned at an angle to one another when beginning to pivot the further one of the panels upon the locking rail of the one of the first and second panels about a pivot axis, with the angle decreasing during placement and with the pivot axis lying in the plane of installation and extending perpendicular to the grooves.

18. A method for disassembling the covering installed according to the method of claim 17, said method comprising:

pivoting the one of the first and second panels, which is engaged underneath by the locking rail, about an upper edge which borders the other one of the first and second panels having the locking rail.
