Abstract
Abstract A load spacer is disclosed for filling the void between containers or articles in a railway boxcar or other freight shipping vehicle or container and the sides thereof to prevent shifting of the load. The load spacer is an expandable, collapsible honeycomb structure which includes a generally planar suspension member laminated to the top of the honeycomb structure. The suspension member includes side portions extending laterally beyond either side of the honeycomb structure and is provided with a score line permitting one side portion to be bent to a position generally perpendicular to the top surface of the suspension member. This side portion includes a pair of flaps which are bendable inwardly over the top surface of the suspension member to prevent the one side portion from being bent beyond the perpendicular. In use, the other side portion rests on the top of the article of freight while the side portion bent into the perpendicular relationship lies against the vertical side wall of the container. This relationship prevents the load spacer from falling down between the load and the side wall of the vehicle during use. A bendable wire runs along the length of the one side portion of the suspension members having the flaps to hold the flaps in their inwardly bent position during use.
