Abstract

Boulon de sécurité. Il comprend une tête à une extrémité, une tige et une seconde extrémité à proximité de laquelle un dispositif maintient le boulon dans le trou d'une pièce Un conduit axial, débouchant à la seconde extrémité, coupe un conduit orienté latéralement. Un verrou monté dans le conduit orienté latéralement peut effectuer un mouvement de va-et-vient de façon à dépasser la périphérie de la tige ou à être escamoté entièrement. Une came, qui comprend deux surfaces, peut coulisser dans le conduit axial. Le verrou comprend deux contre-cames portant contre les surfaces de came, de sorte que sa position latérale ne dépend que de la position axiale de la came qui est poussée vers une position qui correspond à l'extension maximale du verrou. Application au montage d'éléments, par exemple d'un train d'atterrissage.Safety bolt. It comprises a head at one end, a rod and a second end near which a device holds the bolt in the hole of a part. An axial duct, opening at the second end, cuts a duct oriented laterally. A latch mounted in the laterally oriented duct can perform a reciprocating movement so as to extend beyond the periphery of the rod or to be fully retracted. A cam, which has two surfaces, can slide in the axial duct. The lock comprises two cams bearing against the cam surfaces, so that its lateral position depends only on the axial position of the cam which is pushed towards a position which corresponds to the maximum extension of the lock. Application to the assembly of elements, for example a landing gear.
