Panel comprising a locking system

Abstract

The invention relates to a panel ( 1, 2 ) comprising a quadrangular panel portion of coated wood material wherein mutually opposite edges of the panel ( 1, 2 ) have mutually complementary positively locking profiles ( 3, 4 ) so that similar panels ( 1, 2 ) can be assembled, wherein the surface of at least one of the positively locking profiles ( 3, 4 ) has at least in region-wise manner raised portions ( 5, 6, 7 ) and recesses ( 8, 9 ), the raised portions ( 5, 6, 7 ) during assembly of two panels ( 1, 2 ) can be ground down by friction, and the recesses ( 8, 9 ) are of a volume in which resulting abrasion particles ( 5 a, 6 a, 7 a ) from the projections ( 5, 6, 7 ) can be received.

1 - 7 . (canceled)  
   
   
       8 . A panel comprising a quadrangular panel portion of coated wood material, wherein mutually opposite edges of the panel have mutually complementary positively locking profiles so that similar panels can be assembled, and wherein the surface of at least one of the positively locking profiles has at least in region-wise manner raised portions and recesses, characterized in that the raised portions are provided with an overdimension, that the overdimension can be ground away by friction during assembly of two panels, and that the recesses are of a volume in which resulting abrasion particles from the raised portions can be received.  
   
   
       9 . The panel according to  claim 8  characterized in that the positively locking profile is in the form of a groove profile with an undercut configuration and the oppositely disposed positively locking profile is in the form of a tongue profile with an undercut configuration.  
   
   
       10 . The panel according to  claim 9  characterized in that the raised portions and recesses are provided on the tongue profile and the groove profile has a smooth surface which is in contact with the raised portions in the positively lockingly assembled condition.  
   
   
       11 . The panel according to  claim 10  characterized in that the raised portions and recesses are arranged at a tongue underside which faces towards a laying surface.  
   
   
       12 . The panel according to  claim 8  characterized in that the stiffness of the positively locking profiles and the abrasion resistance of the raised portions are so matched to each other that forces which occur during the assembly procedure can cause the raised portions to be rubbed away but cannot cause elastic deformation of the positively locking profiles.  
   
   
       13 . The panel according to  claim 8  characterized in that there is provided a sealing and lubricating agent at least in the recesses.  
   
   
       14 . The panel according to  claim 13  characterized in that the sealing and lubricating agent forms a lubricating film.
