Combined set comprising at least a first and a second floor covering laminated panel

Abstract

A combined set comprising at least a first and a second floor covering laminated panel, said panels being provided with coupling parts comprising a tongue applied on a first lateral edge and a groove applied on a second lateral edge, said panels further comprising locking means provided for mutually engaging said first and second panel when coupled, said locking means comprising a first locking member having a first inclined face with a first slope and starting from a front end of said tongue and extending towards a first cavity in a direction towards an under side of said panel, said locking means having a second locking member comprising a lower lip having a second inclined face with a second slope corresponding to said first slope in such a manner that said first and second inclined face contact each other offset of said groove when said first and second panel are mutually engaged.

1 . A combined set comprising at least a first and a second floor covering laminated panel, each panel comprising a wood-based core as well as a first and a second lateral edge extending at opposite sides of a same panel and in parallel to each other, said first and second lateral edge being provided with coupling parts integrally formed with said core and comprising a tongue applied on said first lateral edge and a groove applied on said second lateral edge, said tongue and groove being configured to co-operate by coupling said first and second panel, said panels further comprising locking means provided for mutually engaging said first and second panel when coupled, said locking means comprising a first locking member formed by an extension on a lower side of said tongue and a second locking member formed by a lower lip extending distally from a lower side of said groove, said second locking member comprising a tooth situated at an end portion of said lower lip and provided to engage into a first cavity of said first locking member when said first and second panel are coupled, said tongue and groove having each an upper side provided to extend in parallel to each other and to contact each other when coupled, characterised in that said extension forming said first locking member has a first inclined face with a first slope and starting from a front end of said tongue and extending towards said first cavity in a direction towards an under side of said panel, said lower lip having a second inclined face with a second slope corresponding to said first slope in such a manner that said first and second inclined face contact each other offset of said groove when said first and second panel are mutually engaged.  
     
     
         2 . A combined set as claimed in  claim 1 , characterised in that a second cavity is provided at a first transition between said second inclined face and said tooth, and wherein a protrusion is provided at a second transition between said first inclined face and said first cavity, said second cavity and said protrusion being positioned and dimensioned in such a manner as to mutually engage when said first and second panel are mutually engaged.  
     
     
         3 . A combined set as claimed in  claim 2 , characterised in that said second cavity has a radius of less than 1 mm and said protrusion has a radius of less than 1 mm.  
     
     
         4 . A combined set as claimed in any one of the claims  2  or  3 , characterised in that said tooth has a first contact face extending from said second cavity in an upward direction with respect to said underside and inclined towards an extremity of said second locking member over a first inclination angle, said first cavity having a first cavity side extending from said protrusion in an upward direction with respect to said underside and turned away from said front side of said tongue over a second inclination angle, said first and second inclination angle having a corresponding value.  
     
     
         5 . A combined set as claimed in  claim 3 , characterised in that said first and second inclination angle have a value of approximately  45 °.  
     
     
         6 . A combined set as claimed in any one of the  claims 1  to  5 , characterised in that said second inclined face starts from an end point of said groove situated at said second lateral edge.  
     
     
         7 . A combined set as claimed in any one of the  claims 1  to  6 , characterised in that an open space is applied between said tooth and first cavity when said first and second panel are engaged.  
     
     
         8 . A panel as a component belonging to a combined set as claimed in any one of the  claims 1  to  7 .
