ABSTRACT:
A latch mechanism is disclosed which includes a housing in which a rotor assembly is rotatably journalled within the housing and rotatable between fully locked and unlocked positions. The rotor assembly is provided with a movable member or latching surface for latching to an eyebolt or the like. An indicator flag is slidably mounted in the rotor assembly and is restricted to common rotation with the rotor assembly. The flag is slidably movable between an extended position wherein a portion of the flag extends out of the rotor assembly and a recess position where the flag is not visible externally of the rotor assembly. The flag is biased to the extended position so that it remains extended and visible until the rotor assembly is moved to a fully locked position. The flag remains in the recessed position only when the rotor assembly is in the fully locked position. A plunger which is slidably mounted within the housing substantially perpendicular to the flag couples with the flag to prevent the flag and rotor assembly from rotating. The plunger can only be coupled with the flag when the rotor assembly is in the fully locked position and the flag is in the recessed position.
