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.
Claims9
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, said retaining means being manually operated,
- wherein said locking device further comprises at least one manually operated 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,
- wherein a portion of the linkage capable of engaging with the bolt so as to block the return of the linkage into its second position is a rod mounted so as to be translationally moveable,
- wherein the rod has a longitudinal lumen capable of engaging with a rod borne by the bolt and used as an abutment for the linkage rod.
A turbine engine nacelle comprising at least one moveable cowl comprising at least one 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, said retaining means being manually operated,
- wherein said locking device further comprises at least one manually operated 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,
- wherein the device further comprises several locking pairs, notably positioned along a locking line, the associated linkages being connected together through at least one mechanical transmission means.
