Aircraft door locking/unlocking mechanism with support arm
A recently granted patent (Publication Number: US11920386B2) details an innovative aircraft door design that includes a leaf with a door structure, an external wall, and door stops, along with a surround featuring a door frame fixed to the aircraft fuselage. The door also incorporates a support arm connected to the leaf, allowing movement between closed, unlocking, and open positions. A locking and unlocking mechanism, controlled by internal and external levers, facilitates this movement. The mechanism includes a control shaft, guide track, actuating finger, and mechanical transmission, enabling smooth operation of the door.
Furthermore, the patent outlines various configurations and components of the aircraft door, such as the actuation configuration where the actuating finger interacts with the guide track and fork, and the release configuration where the levers are in the unlocking position. The mechanical transmission involves a cam, connecting rod, and guide lever to ensure precise movement of the actuating finger. Additionally, the support arm's connection to the leaf allows for longitudinal and transverse movement, while a pivot arm enables pivoting of the leaf. The door stops and frame stops ensure secure closure of the door, while the guide track's ranges dictate specific movements of the support arm and leaf. Overall, the patented aircraft door design offers a sophisticated and efficient system for unlocking and opening the door in various directions, enhancing safety and functionality in aircraft operations.
