Patent

CA 2461268

The invention relates to a fixing element (700) comprising a fixing section (702) and a tubular stamped and/or riveted section (704). The stamped and/or riveted section is embodied in such a way as to enable the fixing element to be placed on a metal part and the fixing section is embodied in such a way as to enable an object to be placed on the metal part. A bearing surface (708) is provided in the region of the transition between the fixing section and the stamped and/or riveted section, extending in a radial and/or conical manner, said bearing surface optionally exhibiting torsional fixing features (701, 702) and the free front end area (714) of the tubular stamped and/or riveted section is provided with a conical cutting surface (716) which is divergent on the radially inner side in the direction of the free front end area and a rounded impact and traction surface (718) on the radially outer side. The cutting surface and the impact and traction surface meet at a ring-shaped front edge (720) on the free front end of the stamped and/or riveted section. The invention is characterized by the shape of the rounded impact and traction area which prevents shavings from occurring.

L'invention concerne un élément de fixation (700) comportant une partie fixation (702) ainsi qu'une partie tubulaire poinçonnée et/ou de type rivet (704). Cette partie poinçonnée et/ou de type rivet est conçu pour permettre la fixation de l'élément de fixation sur une pièce en tôle, et la partie fixation est conçue pour permettre la fixation d'un objet sur ladite pièce en tôle. Une surface d'appui (708) radiale et/ou conique est prévue dans la zone intermédiaire entre la partie fixation et la partie poinçonnée et/ou de type rivet, et présente éventuellement des caractéristiques anti-rotation (701, 702). La partie tubulaire poinçonnée et/ou de type rivet présente au niveau de son extrémité libre (714), sur la face radiale interne, une surface de coupe (716) conique divergeant vers ladite extrémité libre, et sur la face radiale externe une surface de choc et de traction (718) arrondie. La surface de coupe ainsi que la surface de choc et traction se rencontrent au niveau d'une arrête annulaire (720) située sur l'extrémité libre de la partie poinçonnée et/ou de type rivet. L'invention est caractérisée en ce que la surface de coupe conique ainsi que la surface de choc et de traction arrondie présentent une forme particulière empêchant la formation de copeaux.
