Abstract: The present disclosure relates to a door for a transport means, which structurally provides the largest possible door width. Using a movable carrier arm device, the width of the door aperture can be reduced with little complexity from about 42 inches (Type “A”) as an additional equipment option to about 34 inches (Type “C”). To this end, the movable, for example, foldable, carrier arm device is provided which, when the door opens, automatically moves from a retracted position to an extended position in order to reduce the door aperture width to a value which has been predetermined for evacuation. Afterwards, the extended carrier arm device can be folded in again. In this manner, it may be possible to increase the comfort for the passengers and the crew when the aircraft is in the normal operating state since the carrier arm device provides a greater aperture width in the retracted position.

The link set is adapted for cooperative movement so as to facilitate an upward rotational and translational progression of the closure panel (20) in relation to the base (14).

Abstract: An operator and secondary lock for a jalousie window includes a linkage with two toggle joints and a locking lever having a camming edge. The toggle joints assist in locking the window in its fully opened or fully closed position. The toggle joints are actuated by a lever mounted to the window frame so as to provide a mechanical advantage for operation of the jalousie window. The secondary lock engages a lower connecting bar when the windows are in their closed position to prevent opening of the windows by negative air pressure or by prying. The mechanical advantage afforded by the operator allows relatively heavy jalousie window louvers and associated moving components to be actuated over a tolerable range of actuating forces. In addition, brakes permit the louvers to be held frictionally at any fixed orientations between the fully opened and fully closed positions of the window.

Abstract: An operator for a jalousie window includes a linkage with two toggle joints. The toggle joints assist in locking the window in its fully opened or fully closed position. The toggle joints of the operator are actuated by an actuating lever which is mounted to the window frame of the jalousie window so as to provide a mechanical advantage to operation of the jalousie window. The mechanical advantage afforded by the operator allows relatively heavy jalousie window louvers and associated moving components to be actuated by means of a tolerable range of actuating forces. The operating linkage is equipped with brakes which permit the louvers of the window to be maintained in any number of fixed orientations between the fully opened and fully closed position of the window.

Abstract: A hatch assembly for closing an overwing emergency exit opening formed in the body of an aircraft. The hatch (10) includes a plug-type hatch frame (24) and a pair of hinge arms (36) providing swinging movement of the hatch between a closed position and a fully open position that is spaced above and outboard of an opening (12) in the body (14) of an aircraft. Triggering movement of either an internal handle (62) or an external (106) disengages a latch (126) operable when the hatch is in the closed position, thereby placing the hatch in an unlatched condition. Further movement of either handle causes a pair of compression springs (50) coupled to the hinge arms to automatically drive the hatch slightly inward and upward from the closed position to an intermediate lifted position to clear a stop mechanism (32 and 34), and then outward to the open position.

Abstract: Articulation fittings for window casings which partially covers the dormant casing and openings according to Italian art include lower compass arms and upper articulation members which cause the top rail of the window casing to project from the dormant casing during window opening movement. To detach immediately the top rail of the window casing from the dormant casing and thus avoid a premature wear and tear of the sealing joints adhering to the window casing, the articulation fittings are provided with means, which at the very beginning of the opening movement, cause the window casing to follow a path having a vertical component while causing the top rail of the window casing to follow a path having a horizontal component.

Abstract: A retractable backlight apparatus for vehicles includes arcuate-shaped guide tracks mounted within the vehicle on opposite sides of the backlight panel. Rollers operably driven by a drive motor and connected to the backlight panel ride within the guide tracks to move the backlight panel between a raised, angled position closing the rear opening in the vehicle roof structure to a retracted, substantially vertical, stowed position within the interior of the vehicle. In one embodiment, a link is connected between a roller and the backlight panel and provides a final pivoting movement of the bottom edge of the backlight panel to bring the backlight panel into secure, sealing engagement in the vehicle roof structure when in the raised condition. A closure panel is pivotally mounted within the vehicle forward of the backlight panel and operably connected to the backlight panel to control the tilting movement of the backlight panel as the backlight panel moves between the raised and retracted positions.

Abstract: An outward-opening, plug-type cargo door for an aircraft is movable between a closed position and an open position in which the door is spaced from the cargo bay opening in a canopy orientation above and outboard of the cargo bay opening. The door hinges are directly driven by irreversible rotary actuators such that the weight of the door cannot back-drive the actuators. The door must be powered to the opened and closed positions thereby eliminating the necessity of a strut to prop the door open when cargo is being loaded and unloaded. The rotary actuators are mounted to the aircraft structure independently of the hinge mechanism's attachment to the aircraft structure so that the actuators can be removed and replaced if necessary without disturbing the hinge mechanism or door linkage. The hinge linkage has been simplified to provide fewer parts for the linkage. The door is manually unlatched from either the interior or exterior of the aircraft through a dual handle system.

Abstract: An improved linkage mechanism for the opening and closing of a transom-type window, allowing for the window sash to fit tightly within the window frame in a closed position while, on the other hand, allowing for maximum open space for escape through the window frame when the window is opened. A tight fit between the sash and frame of the window is accomplished by having flanges on the sash and linkage means which causes the window sash to be first translated away from the window frame upon opening, providing enough clearance for the window to then be pivoted to an open position on a pivotal axis disposed away from the frame. The linkage is also designed to allow for maximum open space for individuals to escape through the window frame in an open position and a latch mechanism for holding the window in the full-open position for escape.

Abstract: Right and left hand casement windows employ a simple and compact operating linkage which can be installed either to the right or to the left of a center mounted gear drive, thus accomplishing universal operation of left or right hand windows through a structurally identical linkage. Locking tabs provided on an operator link of the mechanism coact in right or left hand mode of operation with locking projections on a stabilizer link to assure positive and secure closing of the window even in cases where the primary jamb-mounted window sash latch is unfastened.
