Patent ID: 8801321

Claim:
A system including: an element including a latch with a housing that rotatably receives a shaft of an active portion of the latch axially extending therethrough, the latch further comprising a pair of nipples axially extending from the housing; and a device for locking/unlocking the latch, comprising: a cylindrical sheath receiving coaxially: a first hollow rod that can rotate relative to an axis of revolution of the sheath and comprising a top end of the first hollow rod which includes a pair of apertures for interlocking with the nipples of the latch of the element when the nipples are received within the apertures and the first hollow rod is rotated; and a second rod, coaxial to and on the inside of the first hollow rod, that can move independently in translation and in rotation relative to the first hollow rod, respectively along and around the axis of revolution of the sheath, and comprising a top end of the second rod which includes a central recess for interlocking with the active portion of the latch when the active portion is received within the recess and the second rod is translated and rotated, so as to actuate the latch in an operational position of locking or of unlocking; two link arms, each coupled to a respective one of the rods for rotating each of the two rods relative to the axis of revolution of the sheath, independently of one another; and a cam with an axis of rotation perpendicular to the direction of translation, the cam abutting a piston colinear with and coupled to a lower end of the second rod, for translating the second rod along the axis of revolution independently of the rotation of the second rod.
