Closing system interposed between two elements
View Patent ↗The invention relates to a closing system interposed between two elements that can occupy an open position and a closed position with respect to each other, the system comprising at least one main locking mechanism. The system according to the invention also comprises at least one emergency locking mechanism that is automatically engaged when the two elements are moved from the open position to the closed position, each emergency locking mechanism being able to be activated only when at least one main locking mechanism is not locked.
1. Closing system interposed between two fan cowls of an aircraft engine pod that can occupy an open position and a closed position with respect to each other, the system comprising:
at least one main locking mechanism, and
at least one emergency locking mechanism that is automatically engaged when the two fan cowls are moved from the open position to the closed position, the at least one emergency locking mechanism capable of being activated when the at least one main locking mechanism is not locked, the at least one emergency locking mechanism includes a first and a second complementary shaped parts, installed on a first and a second of the two fan cowls respectively,
wherein said at least one main locking mechanism comprises a first part and a second part installed on the first and second of the two fan cowls, respectively, said first part for engaging said second part, wherein the first part is a hook coupled to the first of said two fan cowls and the second part is a lever hinged on the second of the two fan cowls.
2. Closing system according to claim 1 , characterized in that each emergency locking mechanism are activated when the two fan cowls move from the closed position towards the open position.
3. Closing system according to claim 1 , characterized in that the hinged lever is coupled to mechanical return means configured to maintain the hook and the hinged lever engaged to each other.
4. Closing system according to claim 1 , characterized in that the at least one emergency locking mechanism is coupled to disengagement means.
5. Closing system according to claim 1 , characterized in that the at least one main locking mechanism is a quick fastening mechanism.
6. Closing system according to claim 1 , characterized in that at least one guide pin is located proximal to the at least one emergency locking mechanism.
7. Closing system according to claim 1 , characterized in that the at least one main locking mechanism comprises a handle configured to disengage the at least one emergency locking mechanism.
8. Closing system according to claim 1 , wherein the at least one emergency locking mechanism further comprises a plurality of emergency locking mechanisms, wherein at least one of the plurality of emergency locking mechanism are located on lateral portions of the fan cowls.
