Abstract
(EN)
Various embodiments are directed towards a nuclear latch assembly. The assembly includes a latch housing and a latch mechanism. The latch mechanism includes a projection member. The latch mechanism provides a biasing force on the projection member. Unless an opposing force on the projection member counterbalances the biasing force, the projection member at least partially projects from a surface of the latch housing. The assembly may include a biasing member that provides the biasing force on the projection member. The assembly may include a bolt. The bolt includes a longitudinal axis. A bore included in the housing is sized to receive the bolt. When the bore receives the bolt, the housing is rotatable about the longitudinal axis of the bolt. The latch mechanism includes a side bore that receives the projection member, the biasing member, and a disk intermediate the projection member and the biasing member.

Selon divers modes de réalisation, l’invention porte sur un ensemble de loquet nucléaire. L’ensemble inclut un logement de verrou et un mécanisme de verrou. Le mécanisme de verrou inclut un organe de projection. Le mécanisme de verrou applique une force d’inclinaison sur l’organe de projection. À moins qu’une force opposée sur l’organe de projection contrebalance la force d’inclinaison, l’organe de projection se projette au moins partiellement depuis une surface du logement de verrou. L’ensemble peut inclure un organe d’inclinaison qui applique la force d’inclinaison sur l’organe de projection. L’ensemble peut inclure une targette. La targette inclut un axe longitudinal. Une perforation incluse dans le logement est taillée pour recevoir la targette. Lorsque la perforation reçoit la targette, le logement peut tourner autour de l’axe longitudinal de la targette. Le mécanisme de verrou inclut une perforation latérale qui reçoit l’organe de projection, l’organe d’inclinaison, et un disque intermédiaire entre l’organe de projection et l’organe d’inclinaison.
