Abstract
A chassis frame is provided with a reinforced floor section and barrier sections fixed to the floor section in longitudinally spaced relationship to one another. Door openings are formed between the barrier sections to either side of the frame. The floor section is of a reduced width and the barrier sections include outwardly convex curvilinear side portions extending laterally relative to the floor section. Door panels are carried by the side portions for slidable movement relative thereto in a curvilinear path defined by the shape of the side portions between extended positions bridging the door openings and retracted positions stowed beneath the floor section. The door panels are tension, compression and torsion resistant and, when in the extended positions, mutually engage the floor section and the sides of the door openings to impart rigidity to the frame.
