Laminate flooring with coupling stem

Abstract

Laminate flooring with coupling stem comprising long rectangular planks with two types of couplings, wherein the first is carried out by their longitudinal edges equally equipped with male/female hooks-type profiles configured for angular penetration, where the hook from a plank can penetrate into the corresponding hook of the other plank, the planks placed in a coplanar position, whereas the second coupling allows the joinery of the tops using a mechanical coupling comprising an engagement stem divided into two longitudinal halves, whose upper and lower faces equally have longitudinal microteeth, where the teeth on one side are slanted towards the center of the stem, such that each longitudinal half of said profile can be penetrating and self-locking in the grooves on the transversal edges the planks, thus finalizing the side by side engagement between the two planks.

1 . A laminate flooring, comprising:
 (1) multiple rectangular planks, the planks having:
 (1a) a first and a second longitudinal edges having sidelong longitudinal coupling profile comprising a male kind hook on the first edge and a female kind hook on the second edge, the profiles constructed and arranged for angular coupling penetration; 
 (1b) a first and a second transversal edges having sidelong transversal coupling profile comprising a lower and an upper horizontal walls of same length, defining a groove; 
   (2) multiple coupling stems for coupling the transversal edges of the multiple planks, the stems of a length similar to the transversal length of the planks to be coupled and having a substantially rectangular shape, and having:
 (2a) a flat central section having two opposite sides; 
 (2b) two longitudinal opposite sidelong edges, each edge integrally attached to one of the opposite sides of the central section, and each edge having un upper and a lower surfaces having equal longitudinal opposite microteeth slanted towards the center of the stem; 
   wherein, in the angular coupling penetration the male kind hook on the first edge of one plank is positioned at a slant such that the male hook penetrates into the corresponding female hook of the second edge of another plank and, the one plank placed on a coplanar position in relation to the another plank, finalizing the longitudinal engagement between planks, and   wherein, each longitudinal opposite sidelong edge of the coupling stems penetrate the grooves of each of the first and the second transversal edges of the planks, coupling the transversal edges of the planks, and   wherein the longitudinal coupling of the planks together with the transversal coupling of the planks allows for a complete assembly of the laminate flooring.   
   
   
       2 . A laminate flooring, comprising:
 (2) multiple rectangular planks, the planks having:
 (1a) a first and a second longitudinal edges having sidelong longitudinal coupling profile comprising a male kind hook on the first edge and a female kind hook on the second edge, the profiles constructed and arranged for angular coupling penetration; 
 (1b) a first and a second transversal edges having sidelong transversal coupling profile comprising a shorter lower horizontal wall and a longer upper horizontal wall, defining a groove; 
   (2) multiple coupling stems for coupling the transversal edges of the multiple planks, the stems of a length similar to the transversal length of the planks to be coupled and having a substantially rectangular shape, and having:
 (2a) a central section having un upper surface and a lower surface and two opposite sides; the upper surface including an upper tapered protrusion with a flat upper edge and the lower surface including a lower protrusion with two straight lateral sides and one straight lower side; 
 (2b) two longitudinal opposite sidelong edges, each edge integrally attached to one of the opposite sides of the central section, each edge having un upper and a lower surfaces having equal longitudinal opposite microteeth slanted towards the center of the stem; 
   wherein, in the angular coupling penetration the male kind hook on the first edge of one plank is positioned at a slant such that the male hook penetrates into the corresponding female hook of the second edge of another plank and, the one plank placed on a coplanar position in relation to the another plank, finalizing the longitudinal engagement between planks, and   wherein, each longitudinal opposite sidelong edge of the coupling stems penetrate the grooves of each of the first and a second transversal edges of the planks, the upper tapered protrusion of the upper surface substantially filling the upper space between the planks, the flat upper edge of the tapered protrusion touching the longer upper walls of the planks; the lower protrusion of the lower surface completely filling the lower empty space between the planks, the two straight lateral sides touching the edges of the shorter lower walls of the planks, and the straight lower side of the lower protrusion, placed coplanar in relation to the lower walls of the planks; coupling the transversal edges of the planks, and   wherein, the longitudinal coupling of the planks together with the transversal coupling of the planks allows for a complete assembly of the laminate flooring.
