Abstract
(EN)
The invention relates to an attachment member (R) of the "lockbolt" type comprising a pin (100) and a ring (200), said pin (100) comprising a head (110) at one end and having, on its body, a first part (120) grooved with a plurality of locking grooves or channels (121p, 121c, 121d) enabling the ring (200) engaging with the pin (100) to attach itself thereto by deformation, and a second part (130) that is grooved in order to cooperate with a tool (O), characterised in that said grooved part (120) of the pin (100) is preformed so as to provide a series of non-helical grooves (121p, 121c, 121d), the beginning and the end of the series consisting of grooves (121p, 121d) that have different profiles from the identical grooves (121c) located in the central part of said series, the different profile having an identical depth but a greater width compared to the profile of the grooves (121c) located in the central portion of the series. The invention is applicable to the production of attachments and rivets.

L'invention concerne un organe de fixation (R) du type "lockbolt" comprenant une broche (100) et une bague (200), ladite broche (100) comprenant une tête (110) à une extrémité et présentant sur son corps, une première partie rainurée (120) d'une pluralité de rainures ou gorges de blocage (121p, 121c, 121d) permettant à la bague (200) s'engageant sur la broche (100), de venir s'y fixer par déformation et une deuxième partie (130) rainurée à des fins de coopération avec un outil (O), remarquable en ce que ladite partie rainurée (120) de la broche (100) est préformée pour présenter une succession de rainures non hélicoïdales (121p, 121c, 121d) dont le début et la fin sont constitués par des rainures (121p, 121d) de profils différents de celles (121c) identiques situées dans la partie centrale de ladite succession, le profil différent adoptant une profondeur identique mais une largeur supérieure à celles du profil des rainures (121c) situées en portion centrale de la succession. Applications : fabrication des fixations, des rivets.
