  • Patent number: 4439076
    Abstract: A movable device for restraining freight in a cargo area in a freight transporting vehicle, for use with a track extending along the cargo area at the top side portions of the vehicle. The device includes an upright stanchion having a vertically extending cargo restraining surface on one side normal to the track. A carriage rolls along the track to permit moving the restraining device to a desired position, and locking pins secure the stanchion in that position. A yoke connects the carriage with the stanchion, to provide a support framework for the stanchion that is rigid throughout its entire extent, in the vertical plane that passes through the center of gravity of the stanchion and is normal to the track, from the rollers of the carriage, along the roller axle and any supporting structure, along the yoke member, and across the stanchion to the vertical plane that passes through the center of gravity of the stanchion and is parallel to the track.
