    Abstract: The invention concerns an aerial vehicle (1) comprising a fuselage structure (3) having an aperture (7) and a door structure (5), which is latched and locked to the fuselage structure (3), and a method for securing the door structure (5) to the fuselage skin structure (3). An aperture perimeter (9) of the fuselage structure (3) surrounds the aperture (7). At least a portion of the aperture perimeter comprises (9) a door latch fitting securing device (13) having an elongated latch bar (15) configured for linear motion and engagement with a stationary latch fitting (11) of the door structure (5) in a latched position. The door latch fitting securing device (13) further comprises a rotatable lock member (17) configured for rotary motion for engagement with and for locking the elongated latch bar (15) in the latched position. An actuator device (19) is coupled to the door latch fitting securing device (13) via a translation mechanism (21) configured to convert rotary motion of the actuator device (19) into said linear motion and into said rotary motion.

    Abstract: The present invention regards a method of securing a movable latch member of a self- securing latch arrangement (1) configured to latch an aircraft door (3, 803) to an aircraft fuselage (7). The present invention also regards the self-securing latch arrangement (1) comprising a movable latch member (9, 809) configured to be movable from an open position to a latch position, an anchorage-shaped latch fitting (11, 811) comprising a latch fitting end (13, 13', 3'', 13''') configured for rigid engagement with an abutment surface (19, 819) of the movable latch member (9, 809) when a pressure differential between the aircraft fuselage interior (8) and the atmosphere (atm) generates a force (F) that pushes the aircraft door (3, 803), and thereby the anchorage-shaped latch fitting (11, 811) or movable latch member (9, 809), in a direction outward. The movable latch member (9, 809) comprises a latch fitting end facing side (17) and the latch fitting end facing side (17) comprises an indentation (18, 818) forming said abutment surface (19, 819).

    Inventor： SCHUSTER, Samuel ,  NORDQVIST, Jonas

    IPC: B64C1/14

    Abstract: The present invention regards an interlock arrangement (1) comprising a latch fitting member (3) of a first body (5) and a laterally moveable latch bar member (7) of a second body (9), which interlock arrangement (1) is configured for latching the first body (5) to the second body (9) in a closed position (Cp), the laterally moveable latch bar member (7) is configured to subsequently latch the latch fitting member (3) into a latching position (Lp); the latch fitting member (3) is configured to move with the first body (5) making a first motion (M1) from an open position (Op) to the closed position (Cp). The arrangement (1) comprises a blocking member (12) configured to block a stop surface (13) of the laterally moveable latch bar member (7) for blocking the laterally moveable latch bar member (7) to make a second motion (M2) from an unlatching position (Up) to the latching position (Lp). The blocking member (12) is configured to be pushed away from the stop surface (13) by means of a pressing portion (15) moved together with the first body (5) during the first motion (M1). The present invention also regards a method for secure latching of the first body (5) to the second body (9).
