Abstract
A latch mechanism includes a hook, a displaceable handle, and links connected between the handle and hook for the operation of the latch mechanism. The handle and links cooperate with the hook to hold the latch mechanism in a locked position.
Claims19
A latch mechanism comprising:
- a hook including a hook body and a hook end coupled to the hook body;
- a handle coupled to the hook body for rotation relative to the hook body between a closed position where the handle extends along the hook and an opened position where the handle is spaced apart from the hook end;
- a linkage coupled between the handle and the hook, the linkage configured to move the hook relative to a clevis with rotation of the handle;
- and
- a clevis-sensing mechanism,
- wherein the clevis sensing-mechanism is configured to block the handle from moving to the closed position in response to the hook end being spaced apart from the clevis.

A latch mechanism for retaining a first structure against a second structure, the latch mechanism comprising:
- a hook including a hook body and a hook end coupled to the hook body;
- a handle coupled to the hook body for rotation relative to the hook body between a closed position where the handle extends along the hook and an opened position where the handle is spaced apart from the hook end;
- a linkage coupled between the handle and the hook and arranged for mounting the latch mechanism on the first component, the linkage configured to move the hook relative to a clevis of the second component with rotation of the handle;
- and
- a clevis-sensing mechanism,
- wherein the clevis sensing-mechanism is configured to block the handle from moving to the closed position in response to the hook end being spaced apart from the clevis.
