Abstract
The present invention provides an improved mobile body construction in the field of motor homes having relatively rigid side walls mounted to a floor above a chassis frame. A frame joint system is provided through use of metallic extruded joint members of a lightweight configuration, while maintaining a relatively rigid frame. These joint members are elongated and can be cut to the individual needs of the particular unit under construction, and comprise a hollow interior subdivided into strengthening polygonal cells. A floor interfacing beam is connected to the floor. The floor interfacing beam has a cross-section including two rectangular polygons and an approximately triangular polygon. The three polygons share a common surface which is parallel to the floor and are juxtaposed adjacent one another. A side wall interfacing beam is connected to the side wall, and has a cross-section including both a polygon having four sides and at least two approximately 90-degree angles and a vertical portion. Both of these shapes are connected to a horizontal surface. The floor interfacing beam is connected to the side wall interfacing beam by bringing a side of the approximately triangular polygon into contact with the common horizontal surface, the vertical portion, and the polygon having four sides.
