In addition, an extraction device can be included with the track mechanism having the actuator producing the desired longitudinal displacement for assisting the other actuator in producing the desired transverse displacement of the door relative to the vehicle body.

Abstract: An escape slide container is mounted for selective, upward movement with a track-mounted, overhead sliding door in an aircraft fuselage. Slide deployment mechanism for releasing the container from the door and for attaching it to the floor of the aircraft allows the door to move upwardly independently of the container, leaving the container attached to the floor. An over-center linkage supports the container above the floor while upward movement of the door trips the over-center linkage to propel the container outwardly through the door opening to deploy the escape slide under the urging of gravity. Apparatus for arming and disarming the slide for deployment operates in conjunction with door opening and closing apparatus that simultaneously effects movement of a door carrier to unplug the aircraft door from the opening in the fuselage and initiates upward traverse of the door along a plurality of tracks from which the door is supported at three points.

Abstract: A pocket door is moved between open and closed positions by an electric motor unit mounted on the studs framing the rough opening in which the door is installed. The rotary motion of the motor is translated into linear motion by a cable and pulley arrangement with one of the pulleys being a drive pulley on the shaft of the motor unit and the other being an idler pulley mounted on the track on which the door slides. The cable is attached to the door through a coil-type tension spring. Hence, the door will move when the motor is energized and should the door encounter an impediment upon closing the spring will expand and permit the pulley to slip within the loop of the cable. The motor is controlled by a timer which when activated causes the motor to run for sufficient time to open the door, then hold to enable one to pass through the door opening, and then run in the opposite direction for sufficient time to close the door.

Abstract: A driving and locking mechanism which employs pivoted links for coupling and transmitting motion between driving and driven members. During motion, the links are constrained to a particular mutual position for transmission of driving forces, but at one end of the range of movement, the constraint is removed and the links pivot so that one link comes into normal or over-normal contact with an abutment and so locks the driven member in position. Forces on the driven member will not move it (except in the case where the abutment is resilient to allow limited movement of the driven member in the "locked" position) and movement of the driven member can only be accomplished by movement of the driving member. Thus a separate locking or latching mechanism is not required. The mechanism is particularly applicable to sliding doors, such as those of railway vehicles, where the door needs to be locked or latched in the closed position against forces applied to the door to tend to open it.
