Guide and hand rail with latch

摘要

A multi-positionable rail for the conveyor of an aircraft belt loader having a rail supported by a plurality of parallel posts pivoted to the side wall of the conveyor and to the rail and collapsible under the force of gravity against a stop positioned on the conveyor side wall to a stowed position wherein the posts and rail are within the silhouette of the conveyor. A first support arm pivoted on the conveyor engages a first pin on a post to position the rail above the conveyor to function as a hand rail and a second support pivoted on the conveyor engage a second pin on a post to position the rail intermediate the stowed and hand rail position. A latch trapped on the post above the first pin is urged by gravity to engage the pin to prevent disengagement of the first arm from the first pin.
