  • Publication number: 20230083772
    Abstract: The present disclosure is directed to a bi-fold door system, apparatus, or device including a first panel, a second panel, and a center post. When in a fully closed position, the bi-fold door limits access to a lavatory on an aircraft, and, alternatively, when in a fully opened position, the bi-fold door allows or provides access to the lavatory on the aircraft. When in the closed position, a user within the lavatory may lock the bi-fold door in the closed position by stepping on a foot pedal at an interior of the bi-fold door. The foot pedal mechanically cooperates with a lock rod and an escapement mechanism the user stepping on the foot pedal moves the lock rod from a retracted position to an extended position locking the bi-fold door in the closed position. To exit the lavatory, the user may unlock the bi-fold door utilizing the foot pedal and then interact with a hands-free actuation mechanism to move the bi-fold door from the closed position to the opened position.
