Patent

CA 2503657

The invention relates to a fastener system configured to fasten together at least two parts, one (2) of which includes at least one flange (8) that is caused to bear against a surface of the other part by a plurality of pins (5) each presenting a collar (8) having a non-circular outline. The collar is received in a groove (10) formed in a bearing surface (2a) of one (2) of the parts, and is designed to prevent the pins (5) from turning by abutment against a wall, wherein the outline of each collar (8) includes two substantially opposite plane surfaces (16, 17) that serve as mutual abutments against two adjacent collars.

L'invention concerne un dispositif de fixation d'au moins deux pièces, dont l'une (2) comporte au moins une bride en appui sur une surface de l'autre pièce, au moyen d'une pluralité de goujons (5) présentant des collerettes (8) à contour non circulaire logeant dans une gorge (10) ménagée dans une surface d'appui (2a) de l'une (2) desdites pièces et destinées à assurer l'antirotation desdits goujons (5) par butée contre une paroi, caractérisé par le fait que le contour de chaque collerette (8) comporte deux surfaces planes (16, 17) sensiblement opposées qui servent de butée mutuelle à deux collerettes adjacentes.
