The invention relates to a locking system for mechanical joining of floorboards (1, 1') which have a body (30), a lower balancing layer (34) and an upper surface layer (32). A strip (6) is integrally formed with the body (30) of the floorboard (1) and extends under an adjoining floorboard (1'). The strip (6) has a locking element (8), which engages a locking groove (14) in the underside of the adjoining floorboard (1') and forms a horizontal joint. A tongue (38) and a tongue groove (36) form a vertical joint between upper and lower plane-parallel contact surfaces (43, 45) and are designed in such manner that the lower contact surfaces (45) are on a level between the upper side of the locking element (8) and a plane containing the underside (3) of the floorboard. The invention also relates to a floorboard having such a locking system, a floor made of such floorboards, as well as a method for making such a locking system.
L'invention concerne un système de verrouillage destiné à joindre mécaniquement des éléments de plancher (1, 1') constitués d'un corps (30), d'une couche d'équilibre inférieure (34) et d'une couche de surface supérieure (32). Une bande (6) intégralement formée avec le corps (30) de l'élément de plancher (1) s'étend sous l'élément de plancher (1') adjoint. La bande (6) possède un élément de verrouillage (8) qui engage une rainure de verrouillage (14) pratiquée sous l'élément de plancher (1') adjoint et forme un joint horizontal. Un emboîtement mâle (38) et un emboîtement femelle (36) correspondant forment un joint vertical entre des surfaces de contact (43, 45) parallèles planes, inférieure et supérieure, et sont conçus de telle manière que les surfaces de contact inférieure (45) soient à un niveau compris entre le côté supérieur de l'élément de verrouillage (8) et un plan contenant le dessous (3) de l'élément de plancher. L'invention concerne aussi un élément de plancher comportant un tel système de verrouillage, un plancher réalisé avec de tels éléments, ainsi qu'un procédé de fabrication d'un tel système de verrouillage.
