Patent

CA 2433134

The invention relates to a bolt element (10) comprising a shaft part (12), whose first end (14) is designed to be riveted (16) with a plate element (18), in particular with a sheet steel part. Said bolt element is characterised in that the other end (20) of the shaft part (12) has a spherical configuration (22), whose diameter (D) is greater than that of the shaft part (12). This allows a bolt element comprising a spherical head to be produced in an extremely cost-effective manner and guarantees that the spherical head has no burr, which leads to the abrasion of the socket that glides on the spherical head during operation.

L'invention concerne un élément tourillon (10) présentant une partie tige (12) dont une première extrémité (14) est conçue pour un assemblage riveté (16) avec un élément en plaque (18), notamment avec une tôle. Ledit élément tourillon est caractérisé en ce que l'autre extrémité (20) de la partie tige (12) présente une forme sphérique (22) dont le diamètre (D) est supérieur à celui de la partie tige (12). Ainsi, il est possible de fabriquer de manière particulièrement économique un élément tourillon présentant une tête sphérique, et de garantir que la tête sphérique ne présente pas d'arête provoquant une usure de la cavité destinée à pivoter sur la tête sphérique en fonctionnement.
