Abstract
Systems, apparatuses, and methods provide for a door handle mechanism including a vent panel, a handle lever, and a four bar mechanism. The handle lever has a lift-to-open configuration. The four bar mechanism is coupled to the handle lever and the vent panel. The four bar mechanism is to time sequence operations to close an aircraft passenger door, latch the aircraft passenger door, lock the aircraft passenger door, and close the vent panel in response to the handle lever being toggled between a closed position and an open position.
Claims20
An aircraft passenger door comprising:
- a door main body;
- and
- a door handle mechanism coupled to the door main body, wherein the door handle mechanism comprises:
- a vent panel;
- a handle lever having a lift-to-open configuration;
- and
- a four bar mechanism coupled to the handle lever and the vent panel, the four bar mechanism to time sequence operations to close the aircraft passenger door, latch the aircraft passenger door, lock the aircraft passenger door, and close the vent panel in response to the handle lever being toggled between a closed position and an open position, wherein the four bar mechanism comprises a lock pawl to prevent closing the vent panel until the aircraft passenger door is locked,
- wherein the lock pawl engages a vent monitor tab of a vent monitor while a latch lock finger of a latch mechanism is not engaged with a lock sector of a lock mechanism to prevent the vent panel from closing while the aircraft passenger door is unlocked,
- wherein the lock pawl engages the vent monitor tab while the latch lock finger engages the lock sector to prevent the vent panel from closing while the aircraft passenger door is locked,
- wherein the lock pawl is disengaged from the vent monitor tab while the latch lock finger is engaged with the lock sector so that the lock pawl does not prevent the vent panel from closing while the aircraft passenger door is locked, and
- wherein the lock pawl is disengaged from the vent monitor and the latch lock finger is engaged with the lock sector so that the vent panel is closeable.

A door handle mechanism comprising:
- a vent panel;
- a handle lever having a lift-to-open configuration;
- and
- a four bar mechanism coupled to the handle lever and the vent panel, the four bar mechanism configured to close the vent panel in response to the handle lever being toggled between a closed position and an open position, wherein the four bar mechanism comprises a lock pawl,
- wherein the lock pawl engages a vent monitor tab of a vent monitor while a latch lock finger of a latch mechanism is not engaged with a lock sector of a lock mechanism to prevent the vent panel from closing while a door is unlocked,
- wherein the lock pawl engages the vent monitor tab while the latch lock finger engages the lock sector to prevent the vent panel from closing while the door is locked,
- wherein the lock pawl is disengaged from the vent monitor tab while the latch lock finger is engaged with the lock sector so that the lock pawl does not prevent the vent panel from closing while the door is locked, and
- wherein the lock pawl is disengaged from the vent monitor and the latch lock finger is engaged with the lock sector so that the vent panel is closeable.
5 more elements
A method comprising:
- toggling a handle lever between a closed position and an open position, wherein the handle lever has a lift-to-open configuration;
- timing sequencing of operations to close an aircraft passenger door, latch the aircraft passenger door, lock the aircraft passenger door, and close a vent panel in response to the handle lever being toggled between the closed position and the open position, and wherein the timing of the sequencing of operations is performed via a four bar mechanism coupled to the handle lever and the vent panel;
- during a closing of the aircraft passenger door blocking a vent monitor from rotating via a lock pawl of a locking mechanism engaging the vent monitor;
- engaging, by the lock pawl, a vent monitor tab of a vent monitor while a latch lock finger of a latch mechanism is not engaged with a lock sector of a lock mechanism to prevent the vent panel from closing while the aircraft passenger door is unlocked;
- engaging, by the lock pawl, the vent monitor tab while the latch lock finger engages the lock sector to prevent the vent panel from closing while the aircraft passenger door is locked;
- disengaging the lock pawl from the vent monitor tab while the latch lock finger is engaged with the lock sector so that the lock pawl does not prevent the vent panel from closing while the aircraft passenger door is locked;
- and
- disengaging the lock pawl from the vent monitor and the latch lock finger is engaged with the lock sector so that the vent panel is closeable.
