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 ( 24 a , 24 b ), which are inclined with respect to the surface ( 10 ) of the panel ( 2, 4 ), and lower bearing faces ( 26 a , 26 b ) which are rounded, and with locking means ( 28 a, 28 b ) for fastening the panels ( 2, 4 ) in the same plane with respect to one another, comprising a locking face ( 28 b ) on the tongue and a locking face ( 28 a ) on the groove, wherein the locking faces ( 28 a, 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 ( 28 a, 28 b ) not to be more than 20% of the maximum height M of the long groove cheek ( 18 ).

Claims (10)

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, said 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 said 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 a joined state each have top bearing surfaces ( 24 a , 24 b ) with respect to a top surface of the tongue profile which are inclined with respect to the top surface ( 10 ) of the panel ( 2 , 4 ), and bottom bearing surfaces ( 26 a , 26 b ) which are rounded,

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

wherein the height H of the locking faces ( 28 a , 28 b ) is not more than 20% of the maximum height M of the long groove cheek ( 18 ), wherein at least sections of the top side ( 30 ) of the long groove check ( 18 ) are obliquely arranged, wherein the top bearing surfaces ( 24 a , 24 b ) contact each other when said panels are fixed in the same plane with respect to each other, and wherein the bottom bearing surfaces ( 26 a , 26 b ) contact each other when said panels are fixed in the same plane with respect to each other, and wherein, when the groove and tongue profile ( 6 , 8 ) are moved from a non-engaged position to a positive engagement, no deformation of the groove and tongue profile ( 6 , 8 ) occurs.

2. The panel according to claim 1 , wherein 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° with respect to the top surface ( 10 ) of the panel ( 2 ).

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

4. The panel according to claim 1 , wherein at least sections of said top face ( 30 ) of said long groove cheek ( 18 ) are arranged at an angle (ε) with respect to the top surface ( 10 ) of the panel ( 2 ) which is about half of angle δ taken between the top bearing surfaces ( 24 a , 24 b ) and the top surface ( 10 ) of the panel ( 2 ).

5. The panel according to claim 2 , wherein the angle (ε) is up to 7°.

6. The panel according to claim 2 , wherein the angle (ε) is up to 5°.

7. The panel according to claim 1 , wherein the height H of the locking faces ( 28 a , 28 b ) is not more than 15% of the maximum height M of the long groove cheek ( 18 ).
