(EN) SELF-DRILLING FASTENING ELEMENT
(FR) ÉLÉMENT DE FIXATION AUTO-PERCEUR
Abstract
(DE)
Selbstlochformendes Befestigungselement (10) mit einer rotationssymmetrischen Bohrspitze (16), und einem Schaft (14), bei dem der Querschnitt der Bohrspitze (16) durch einen ersten Radius (R2), dessen Ursprung (22) außerhalb der Rotationsachse (18) der Bohrspitze (16) auf der der Rotationsachse (18) gegenüberliegenden Seite liegt, nahe der Bohrspitze (16) und einen zweiten Radius (R1) nahe dem Schaft (14) begrenzt ist, wobei der Ursprung (26) des zweiten Radius (R1) weiter von der Rotationsachse (18) entfernt ist, als der Ursprung (22) des ersten Radius (R2), und ebenfalls auf der gegenüberliegenden Seite der Rotationsachse (18) liegt.
(EN)
The invention relates to a self-drilling fastening element (10), comprising a rotationally symmetrical drilling tip (16) and a shaft (14), wherein the cross-section of the drilling tip (16) is bounded by a first radius (R2), the origin (22) of which lies outside the rotational axis (18) of the drilling tip (16) on the side opposite the rotational axis (18), near the drilling tip (16), and a second radius (R1) near the shaft (14), wherein the origin (26) of the second radius (R1) is farther from the rotational axis (18) than the origin (22) of the first radius (R2) and likewise lies on the opposite side of the rotational axis (18).
(FR)
L'invention concerne un élément de fixation auto-perceur (10) comportant une pointe de perçage symétrique en rotation (16), et une tige (14), la section transversale de la pointe de perçage (16) étant limitée par un premier rayon (R2) dont l'origine (22) est située en dehors de l'axe de rotation (18) de la pointe de perçage (16) sur le côté opposé à l'axe de rotation (18), à proximité de la pointe de perçage (16), et par un deuxième rayon (R1) à proximité de la tige (14), l'origine (26) du deuxième rayon (R1) étant située plus loin de l'axe de rotation (18) que ne l'est l'origine (22) du premier rayon, et étant également située sur le côté opposé de l'axe de rotation (18).
