An aircraft thrust reverser mechanism comprises a thrust reverser moveable between a deployed position in which at least a portion of gas flowing through the aircraft engine is redirected in a non-rearward direction and a stowed position in which gas flowing through the engine is not redirected. A thrust reverser lock is provided to prevent inadvertent deployment of the thrust reverser. The thrust reverser lock comprises a locking element rotatable about a pivot between a closed position in which the locking element prevents deployment of the thrust reverser and an open position in which the locking element permits the thrust reverser to be deployed. A retractable blocking element prevents the locking element from moving to the second position unless the blocking element is first withdrawn. The locking element is shaped in such a way that if the thrust reverser moves toward a deployed position without the blocking element having first been withdrawn, the force produced by the contact between the thrust reverser and the locking element produces a torque that tends to move the lock into its closed position.

[ What is claimed is:] [1.] A locking mechanism for use with an engine thrust reverser moveable between a stowed position and a deployed position, said locking mechanism comprising:a pivot;a resilient member;a locking element rotatable about said pivot between a first position for preventing deployment of a thrust reversing member and a second position for allowing deployment of said thrust reversing member, said locking element urged by said resilient member toward said second position;said locking element comprising a first surface adapted to engage a locking pin on said thrust reversing member for rotating said locking element from said second position to said first position when said thrust reversing member moves from said deployed position to said stowed position;a blocking member moveable between a blocking position and a retracted position, wherein said blocking position prevents rotation of said locking element from said first position to said second position;means for selectively moving said blocking member away from said blocking position;said locking element further including a second surface adapted to engage said locking pin when said thrust reversing member moves from said stowed position toward said deployed position and when said blocking member prevents said locking element from being urged from said first position to said second position, said second surface being inclined such that engagement of said second surface with said locking pin prevents said thrust reversing member from being deployed while producing no force at said blocking member.
