Abstract
An assembly is provided for an aircraft. This aircraft assembly includes a latch, a balk element and a fitting. The latch is movable between an unlocked position and a locked position. The balk element is rotatable between a balked position and an un-balked position. The balk element is configured to block the latch from moving to the locked position when the balk element is in the balked position. The fitting includes a keeper. The fitting is movable between an open position and a closed position. The fitting is configured to push the balk element into the un-balked position as the fitting moves into the closed position. The latch is configured to move to the locked position and engage the keeper when the fitting is in the closed position.
Claims19
An assembly for an aircraft, comprising:
- a latch movable between an unlocked position and a locked position;
- a balk element rotatable between a balked position and an un-balked position, the balk element configured to block the latch from moving to the locked position when the balk element is in the balked position;
- and
- a fitting comprising a keeper, the fitting movable between an open position and a closed position, the fitting configured to push the balk element into the un-balked position as the fitting moves into the closed position, and the latch configured to move to the locked position and engage the keeper when the fitting is in the closed position;
- wherein the latch is rotatable about a latch axis between the unlocked position and the locked position, the balk element is rotatable about a balk element axis between the balked position and the un-balked position, and the balk element axis is angularly offset from the latch axis.
An assembly for an aircraft, comprising:
- a door moveable between an open position and a closed position;
- a latch rotatable between an unlocked position and a locked position;
- and
- a balk element rotatable between a balked position and an un-balked position, the balk element configured to block the latch from moving to the locked position when the balk element is in the balked position, and the balk element configured to permit movement of the latch to the locked position when the balk element is in the un-balked position, wherein rotation of the balk element is passively actuated as the door moves into the closed position;
- wherein the latch is rotatable about a latch axis between the unlocked position and the locked position, the balk element is rotatable about a balk element axis between the balked position and the un-balked position, and the balk element axis is angularly offset from the latch axis.
An assembly for an aircraft, comprising:
- a stationary structure;
- a door movable between an open position and a closed position;
- a keeper mounted with the door;
- a latch mounted with the stationary structure, the latch movable between an unlocked position and a locked position in which the latch engages the keeper and secures the door to the stationary structure;
- and
- a balk element decoupled from the latch and rotatable between a balked position and an un-balked position, the balk element configured to block movement of the latch to the locked position when the door is not in the closed position, and the balk element configured to permit movement of the latch to the locked position when the door is in the closed position;
- wherein the latch is rotatable about a latch axis between the unlocked position and the locked position, the balk element is rotatable about a balk element axis between the balked position and the un-balked position, and the balk element axis is angularly offset from the latch axis.
