Set of floor panels

Abstract

The floor panel ( 1 ) comprises a concave locking part ( 11 ) with an upper retaining protrusion ( 21 ) and with a lower retaining protrusion ( 22 ), in a male joining part ( 9 ), and a convex locking part ( 12 ) with an upper retaining surface ( 17 ) and with a lower retaining surface ( 24 ), in a female joining part ( 10 ). Furthermore, the male joining part ( 9 ) of the floor panel ( 1 ) has a sealing edge ( 16 ) shaped at its outer side surface ( 6 ′), wherein, in the locked state, this sealing edge ( 16 ) of the male joining part ( 9 ), when engaged with the female joining part ( 10 ) of another floor panel ( 1 ), is pressed down with a fixed force into the upper retaining surface ( 17 ) of the convex locking part ( 12 ).

1 . A set of floor panels, wherein the joined floor panels ( 1 ) are in the form of rectangular plates comprising:
 an upper surface ( 2 ) and a lower surface ( 2   a ) parallel to it, designed to be laid on the subfloor,   two long edges ( 3 ,  3 ′) of side surfaces ( 4 ,  4 ′)   two short edges ( 5 ,  5 ′) of side surfaces ( 6 ,  6 ′)   complementary latching means ( 7 ,  8 ) shaped near the edges ( 3 ,  3 ′;  5 ,  5 ′) being joined to each other,   vertical fixing assembly ( 18 ),   horizontal fixing assembly ( 19 ,  19   a ),   wherein the vertical fixing assembly ( 18 ), serving to lock the floor panels ( 1 ) being joined in a direction perpendicular to the upper surface ( 2 ) of the panel ( 1 ), comprises joining parts made as a male joining part ( 9 ) and a female joining part ( 10 ), which have a vertically active concave locking part ( 11 ) and a convex locking part ( 12 ),   where the concave locking part ( 11 ) has an upper retaining protrusion ( 21 ) and a lower retaining protrusion ( 22 ),   and the convex locking part ( 12 ) has an upper retaining surface ( 17 ) and a lower retaining surface ( 24 ),   wherein the upper retaining protrusion ( 21 ) of the concave locking part ( 11 ) in the locked state rests on the upper retaining surface ( 17 ) of the convex locking part ( 12 ), and the lower retaining protrusion ( 22 ) of the concave locking part ( 11 ) rests on the lower retaining surface ( 24 ) of the convex locking part ( 12 ),   and the horizontal fixing assembly ( 19 ,  19   a ) serving to lock the floor panels ( 1 ) being joined in a direction parallel to the upper surface ( 2 ) of the panel ( 1 ) comprises a horizontally active inner side surface ( 13 ) of the male joining part ( 9 ), wherein this inner side surface ( 13 ), in the locked state, rests against an inner retaining surface ( 14 ) of a protruding engaging element ( 15 ) and comprises a horizontally active outer side surface ( 6 ′) of the male joining part ( 9 ), wherein this outer side surface ( 6 ′), in the locked state, rests against an inner side surface ( 6 ) of the female joining part ( 10 ), characterised in that the male joining part ( 9 ) of the floor panel ( 1 ) has a sealing edge ( 16 ) shaped at its outer side surface ( 6 ′),   wherein, in the locked state, this sealing edge ( 16 ) of the male joining part ( 9 ), when engaged with the female joining part ( 10 ) of another floor panel ( 1 ), is pressed down into the upper retaining surface ( 17 ) of the convex locking part ( 12 ) with a fixed force which achieves a tight joint, even in case of certain imperfections in the linearity of the sealing edge ( 16 ) or in the shape of the upper retaining surface ( 17 ) of the convex locking part ( 12 ),   wherein the sealing edge ( 16 ) is shaped by the inclined upper outer guiding surface ( 20 ) of the male joining part ( 9 ).   
     
     
         2 . The set of floor panels according to  claim 1 , characterised in that the sealing edge ( 16 ) is shaped on the upper retaining protrusion ( 21 ) of the concave locking part ( 11 ). 
     
     
         3 . (canceled) 
     
     
         4 . The set of floor panels according to  claim 1 , characterised in that the sealing edge ( 16 ) has a rounding radius of less than 0.3 mm. 
     
     
         5 . The set of floor panels according to  claim 4 , characterised in that the sealing edge ( 16 ) has a rounding radius within the range from 0.1 to 0.2 mm.
