Sliding vertical steering column for the support and the blockage of the side-doors for all the height in vans and containers with all-opening sides

A door system for gaining access along the full length of a van or container without any obstructions. The side walls of the van consist of panels hinged to moveable support posts. The support posts are slidingly attached to rails at top and bottom of the loading area via runners. The runners that secure the posts are kept perpendicular to the rails are also intended to reinforce the structure when the doors are closed in transport mode. To open the side wall, the doors are swung open to 90 degrees and then the posts are moved to each end of the loading area.
