Floor panel

Abstract

A floor panel ( 1 ) provided with corresponding, mechanical locking elements ( 7, 12 ) on at least two opposed sides ( 5, 6 ) thereof, and having a core ( 4 ), a walk-on surface ( 2 ) and a bottom surface ( 3 ). In order to provide a floor panel of this type with impact sound insulation in a structurally simple and effective manner, it is suggested that at least one recess ( 13, 19 ) is provided, which extends from said bottom surface ( 3 ) into said core ( 4 ).

1 . A floor panel ( 1 ,  1 ′) provided with corresponding, mechanical locking elements ( 7   a,    7   b;    12   a,    12   b ) on at least two sides ( 5   a,    5   b;    6   a,    6   b ) thereof, and comprising a core ( 4 ), a walk-on surface ( 2 ) extending a bottom surface ( 3 ), and at least one recess ( 13 ,  19 ) extending from said bottom surface ( 3 ) into said core ( 4 ).  
   
   
       2 . A floor panel according to  claim 1 , wherein the recess ( 13 ,  19 ) extends into the core ( 4 ) over a distance corresponding to approximately one third up to one half of the thickness (D) of said core ( 4 ).  
   
   
       3 . A floor panel according to  claim 1 , wherein the recess ( 13 ,  18 ) has a width (s) of from 1 to 10 mm.  
   
   
       4 . A floor panel according to  claim 1 , wherein the floor panel is formed of a rectangular shape with short and long sides ( 5   a,    5   b;    6   a,    6   b ), the recess ( 13 ,  18 ) extending continuously from one short side ( 6   a ) to the opposite short side ( 6   b ).  
   
   
       5 . A floor panel according to  claim 1 , and wherein a plurality of spaced-apart recesses ( 19 ) is provided.  
   
   
       6 . A floor panel according to  claim 5 , wherein the plurality of spaced-apart recesses ( 19 ) is arranged in at least one row extending from one short side ( 6   a ) to an opposite short side ( 6   b ) of a rectangular shape.  
   
   
       7 . A floor panel according to  claim 1 , wherein the core ( 4 ) contains a wood fiber material.  
   
   
       8 . A floor panel according to one  claim 1 , wherein the locking elements ( 7 ,  12 ) are implemented such that, when one panel is joined with a neighboring panel, a recess ( 16 ,  17 ) will be formed on the bottom surface ( 3 ).  
   
   
       9 . A floor panel according to  claim 1 , wherein the floor panel is formed so that the long sides ( 5   a,    5   b ) of a rectangular shape are each provided with corresponding, mechanical locking elements ( 7   a,    7   b ) for locking engagement with neighboring neighbouring panels, and a groove-shaped recess ( 13 ) extends from the bottom surface ( 3 ) into the core ( 4 ), the recess extending continuously from one short side ( 6   a ) to the opposite short side ( 6   b ).  
   
   
       10 . A floor panel according to  claim 1 , wherein the floor panel is formed so that the short and the long sides ( 6   a,    6   b;    5   a,    5   b ) of a rectangular shape are each provided with corresponding locking elements ( 7   a,    7   b;    12   a,    12   b ) for engagement with neighboring panels, and a plurality of spaced-apart recesses ( 19 ) extend in an in-line arrangement from the bottom surface ( 3 ) into the core ( 4 ), the in-line arrangement extending from one short side ( 6   a ) to the opposite short side ( 6   b ).  
   
   
       11 . A floor panel according to  claim 1 , and wherein a flooring ( 15 ,  18 ) is produced from a plurality of floor panels ( 1 ,  1 ′).  
   
   
       12 . A floor panel according to  claim 9 , and wherein a flooring ( 15 ) is produced from a plurality of floor panels ( 1 ) being laid parallel to one another.  
   
   
       13 . A floor panel according to  claim 10 , and wherein a flooring ( 18 ) is produced from a plurality of floor panels ( 1 ′) being laid in a herringbone pattern.  
   
   
       14 . A floor panel according to  claim 7 , wherein the wood fiber material is MDF/HDF board.
