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 includes 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 the transition between these positions. The mechanism includes a control shaft, guide track, actuating finger, and mechanical transmission, ensuring smooth operation of the door.
Furthermore, the patent describes 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, including a cam, connecting rod, and guide lever, enables precise movement of the actuating finger during door operation. Additionally, the method for unlocking the aircraft door involves specific movements of the actuating finger over different ranges of the guide track, resulting in the release of door stops and the movement of the leaf in various directions to facilitate opening. Overall, the patented aircraft door design offers a sophisticated and efficient mechanism for secure and reliable operation in an aircraft environment.
