Abstract
A locking device includes a bolt capable of engaging with a corresponding hook, the bolt being mounted against a resilient return spring that tends to return the bolt into a spaced apart position. The locking device further includes a detection linkage, which is moveable between a first position and a second position. In the first position, the linkage enables unlocking of the bolt and the hook. In the second position, the linkage engages with a portion of the locking pair so as to block the unlocking.
Claims11
A locking device between a first structure and a second structure, the locking device comprising:
- at least one locking pair including at least one bolt attached to the first structure and capable of engaging with at least one corresponding retaining means attached to the second structure, the bolt being moveably mounted against at least one resilient return means tending to return it into a moved-apart position of the retaining means,
- wherein said locking device further comprises at least one detection linkage, moveably mounted between a first position in which it allows unlocking of the bolt and of the retaining means, at least one portion of the bolt then being engaged with the linkage, so as to block a possible return of the latter towards a second position, and said second position in which the linkage engages with at least one portion of the locking pair so as to block the unlocking thereof.
