Patent

CA 2616611

A member such as a board (10) configured to interlock with similar such boards, typically for use as flooring. The board (10) comprises an elongate body (11) having first and second opposed faces (13, 15) and two longitudinal sides (17, 19). A first locking portion (12) is provided at one longitudinal side (17) and a second locking portion (22) is provided at the other longitudinal side (19). The first locking portion (21) comprises a tongue (23) presenting a convex face (33), and the second locking portion (22) comprises a groove (41) for receiving the tongue (23) of a similar board disposed adjacent thereto. The groove (41) has a face incorporating a concave portion (49) for receiving the convex face (33) of the tongue (23), whereby interaction between the convex and concave portions (33, 49) serves to draw the tongue (23) of one board into the groove (41) of another board upon relative angular movement between the two boards towards a position whereby they are in side-by-side relation. The first locking portion (21) further comprises a first interlocking element configured as a further groove (38) disposed between the tongue (23) and the second face (15) of the body (11). Additionally, the second locking portion (22) further comprises a second interlocking element configured as a rib (61) disposed between the groove (41) and the second face (15) of the body (11). The rib (61) and groove (38) of adjacent boards are adapted to interlock when the two boards are in side-by-side relation.

La présente invention concerne un élément tel qu~une planche (10) conçue pour s~emboîter avec des planches identiques, de manière classique pour une utilisation dans la réalisation d~un plancher. La planche (10) comprend un corps allongé (11) comportant des première et seconde faces opposées (13, 15) et deux côtés longitudinaux (17, 19). Une première partie de verrouillage (12) est formée au niveau d~un côté longitudinal (17) et une seconde partie de verrouillage (22) est formée au niveau de l~autre partie longitudinale (19). La première partie de verrouillage (21) comprend une languette (23) présentant une face convexe (33) et la seconde partie de verrouillage (22) comprend une rainure (41) destinée à recevoir la languette (23) d~une planche semblable disposée de manière adjacente à celle-ci. La rainure (41) comporte une face intégrant une partie concave (49) destinée à recevoir la face convexe (33) de la languette (23), moyennant quoi une interaction entre les parties convexe et concave (33, 49) sert à faire entrer la languette (23) d~une planche dans la rainure (41) d~une autre planche lors d~un mouvement angulaire relatif entre les deux planches vers une position moyennant quoi elles seront côte à côte. La première partie de verrouillage (21) comprend en outre un premier élément d~emboîtement configuré en tant que rainure supplémentaire (38) disposée entre la languette (23) et la seconde face (15) du corps (11). En outre, la seconde partie de verrouillage (22) comprend en outre un second élément d~emboîtement en forme de nervure (61) disposée entre la rainure (41) et la seconde face (15) du corps (11). La nervure (61) et la rainure (38) de planches adjacentes sont conçues pour s~emboîter lorsque les deux planches sont côte à côte.
