(FR) DISPOSITIF DE BLOCAGE D'ÉCROU ET ENSEMBLE DE MONTAGE ASSOCIÉ
Abstract:
(EN) The present invention relates to a unit (10) for a locking device, including: a nut (12) comprising first (18) and second (20) coaxial taps in opposite directions; and a ring (13); said ring including a third tap (38); the first (18) and third (38) taps being capable of engaging with a single first thread (22); said ring including a second thread (40) capable of engaging with the second tap (20) of the nut. A portion (33) of the ring, projecting relative to the second thread (40), includes a through-hole (60); and a surface (16) of the nut includes a visual marking, configured to be opposite the hole (60) when the nut and the ring are in an installation position, and separated from said hole when the nut and the ring are outside said installation position.
(FR) La présente invention concerne un ensemble (10) pour dispositif de blocage, comportant: un écrou (12) comprenant un premier (18) et un deuxième (20) taraudages coaxiaux et de sens opposé; et une bague (13); ladite bague comportant un troisième taraudage (38); les premier (18) et troisième (38) taraudages étant aptes à coopérer avec un même premier filetage (22); ladite bague comportant un deuxième filetage (40) apte à coopérer avec le deuxième taraudage (20) de l'écrou. Une portion (33) de la bague, en saillie par rapport au deuxième filetage (40), comporte une lumière (60) traversante; et une surface (16) de l'écrou comporte un marquage visuel, configuré pour être en vis-à-vis de la lumière (60) lorsque l'écrou et la bague sont dans une position d'installation, et à l'écart de ladite lumière lorsque l'écrou et la bague sont hors de ladite position d'installation.
