<p>A retractable center guide and vertical and lateral load restraint for a cargo carrying aircraft. The devices are mounted along the center line of the aircraft and in erect position include laterally extending arms adapted to overlie the edges of load carrying structure such as pallets. The devices are pivoted for swinging about axes extending transversely of the aircraft so that if a device is in the path of an advancing load carrying structure, it will be pivoted to retracted position, thus avoiding damage to the device or load carrying structure. Resilient means are provided effectively to maintain the device either in erect or in retracted position, or the resilient means may restore the device to an erect position if it is released after being moved to retracted position. The series of devices together with guide surfaces at the side of the aircraft, constitute an elongated guideway along which load carrying structure may be advanced. Finally, in erect position with load carrying structure at the side of a device, the device operates as a restraint against lateral movement of the load carrying structure.</p> |
