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. A foot pedal at an interior of the bi-fold door may lock 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. When in the opened position, the bi-fold door may be held open for a selected period of time such that the user may exit the lavatory without physically contacting the bi-fold door.

Abstract: The present disclosure is directed to a flight deck barrier apparatus or device including a frame having a first jamb, a second jamb, and a header. A foldable barrier mechanically coupled to the second jamb. An edge beam mechanically coupled to the foldable barrier. The edge beam configured to mechanically cooperate with strikers along the first jamb and mechanically cooperate with strikers along the second jamb. The edge beam including a plurality of catches. Respective ones of the plurality of catches interlock with corresponding ones of the strikers along the first jamb when the foldable barrier is in a stowed position such that a flight deck of an aircraft is accessible. Respective ones of the plurality of catches interlock with corresponding ones of the strikers along the second jamb when the foldable barrier is in an expanded position limiting access to the flight deck barrier of the aircraft.

Abstract: A hinge apparatus can include a frame component of an aircraft interior component, a door component coupled to an aircraft door assembly, and a linkage assembly operable to rotatably move the door component between an open configuration, a partially open configuration, and a closed configuration. The linkage assembly can include a first hinge body coupled to the door component, a second hinge body coupled to the frame component, a main link pivotably coupled to the first hinge body and having a main link surface, and a first link pivotably coupled to the second hinge body and pivotably coupled to the main link. The first link may have a first link surface that is sized and shaped to mate with the main link surface when the door component is in the partially open configuration, the mating preventing movement of the door component from the partially open configuration to the open configuration or the closed configuration. Related methods are also provided.
