Abstract:
An aircraft vent and cargo door locking mechanism for ensuring the opening, closing, and locking of a cargo door in a cargo door opening formed in an aircraft fuselage, comprising:a latch assembly connected to said fuselage and said cargo door for movement between a latched position, wherein said cargo door is in a closed position, and an unlatched position, wherein said cargo door is in an open position; a locking assembly connected to said cargo door for movement between a locked position, wherein said latch assembly is maintained in said latched position by a locking pin, and an unlocked position, wherein said latch assembly may move to the unlatched position; a blocker assembly connected to said cargo door for movement between a blocked position, wherein said blocker assembly positively stops said locking and latch assemblies from moving to said unlocked and unlatched positions, respectively, and an unblocked position, wherein said blocker assembly is disengaged from said locking and latch assemblies, allowing said locking and latch assemblies to move to said unlocked and unlatched positions, respectively; an actuator coupled to said blocker assembly for actuating said blocker between said blocked and said unblocked positions; a vent door mounted adjacent an opening in said aircraft fuselage wherein said opening and said vent door are remote from said cargo door, and said vent door movable between a vent door closed position, wherein said adjacent opening is sealably closed, and a vent door open position, wherein said adjacent opening is open; means for biasing said vent door toward said vent door open position; and said actuator coupled to said vent door for actuating said vent door between said vent door closed position and said vent door open position simultaneously with the actuation of said blocker assembly between said blocked and unblocked positions, respectively.
