ABSTRACT:
A cargo handling system rollout stop assembly, which allows a movable object to freely pass over it in a first or inboard direction but obstructs passage of that object in the opposite or outboard direction. The stop assembly comprises a frame and at least one arm assembly rotatably mounted in the frame. The arm assembly normally extends in an upright position in the path of the movement of the object and is capable of slight translation in the first direction. The arm assembly has a straight or linear camming surface all of whose centerline points are equidistant from the axis of rotation of the arm assembly. When the camming surface engages the object moving in the first direction, the arm assembly is translated slightly in the first direction and rotated downwardly out of the path of the object. A dog clutch assembly releasably connects the arm assembly to the frame. The dog clutch assembly normally prevents the arm assembly from rotating from its upright position, but is uncoupled when the object engages the camming surface causing the arm assembly to translate slightly in the first direction and rotate downwardly. A compression-torsional spring rotates the arm assembly upwardly back into the path of the object after the object has passed beyond the arm assembly. The arm assembly has an abutment surface for contacting the object after the arm assembly has been rotated back to its normal upright position whereby movement of the object in the opposite direction is obstructed. The arm assembly may be locked in a down position for unloading the object in the opposite direction.
