Abstract

The invention relates to a panel designed for mechanical connection with at least one further, identical panel by means of pivoting, with a tongue and groove profile (6, 8) for fastening the panels (2, 4) at the same height with respect to one another, comprising a groove profile (6) with a short groove cheek (14), a groove bottom (16) and a long groove cheek (18) on at least one side of the panel and a tongue profile (8) corresponding to the groove profile (6) on at least one side of the panel, wherein the long groove cheek (18) has a greater thickness (M) at its free end (20) than in the region under the free end of the short groove cheek (14), and wherein in the assembled state the tongue and groove each have upper bearing faces (24a, 24b), which are inclined with respect to the surface (10) of the panel (2, 4), and lower bearing faces (26a, 26b) which are rounded, and with locking means (28a, 28b) for fastening the panels (2, 4) in the same plane with respect to one another, comprising a locking face (28b) on the tongue and a locking face (28a) on the groove, wherein the locking faces (28a, b) on the groove and on the tongue are arranged between the surfaces (10, 12) of the panels (2, 4) in the region of the free end (20) of the long groove cheek (18). To make it possible for the panels to be assembled without deformation and jamming, and thereby avoiding damage during the laying operation, provision is made for the height H of the locking faces (28a, 28b) not to be more than 20% of the maximum height M of the long groove cheek (18).

Claims

1. A panel, prepared for mechanical connection with at least one further, like panel by pivoting, comprising:

a groove and tongue profile (6, 8) for fixing the panels (2, 4) at the same height with respect to each other, including a groove profile (6) having a short groove cheek (14), a groove bottom (16) and a long groove cheek (18) at least on one side of said panel, and a tongue profile (8) corresponding to the groove profile (6) on at least one side of said panel, wherein the long groove cheek (18), at its free end (20), has a greater thickness (M) than in the area under the free end of the short groove cheek (14), and wherein the groove and tongue in the joined state each have top bearing surfaces (24a, 24b) inclined with respect to the top surface (10) of the panel (2, 4), and bottom bearing surfaces (26a, 26b), which are rounded, and comprising

locking means (28a, 28b) for fixing said panels (2, 4) in the same plane with respect to each other, including a locking face (28b) on said tongue and a locking face (28a) on said groove, wherein the locking faces (28a, 28b) are arranged on said groove and on said tongue between said surfaces (10, 12) of said panels (2, 4) in the area of the groove bottom (16),

whereby the height H of the locking faces (28a, 28b) is not more than 20% of the maximum height M of the long groove cheek (18) characterized in that at least sections of the top side (30) of the long groove check (18) are obliquely arranged.

11. The panel according to claim 1, characterized in that at least sections of said top face (30) of said long groove cheek (18) are arranged at an angle ε

which is up to 10°

, preferably up to 7°

, particularly preferably up to 5°

with respect to the top surface (10) of the panel (2).

12. The panel according to claim 1, characterized in that, with the exception of the locking faces (28a, 28b), free spaces (34, 36) are provided between the free end (20) of the long groove cheek (18) and the tongue.

13. The panel according to claim 1, characterized in that at least sections of said top face (30) of said long groove cheek (18) are arranged at an angle ε

which is about half of angle δ

.
