Abstract: A vehicle system for joining sandwich panels has been designed for use in vehicles. The system includes a chassis, a floor, sidewalls, a roof, and a rear panel. The walls are formed as prefabricated sandwich panels with finished surfaces. These panels are joined using single-piece aluminum extrusions in the form of roof rails and floor rails, which allow for quick assembly and strong surface-to-surface load transfer. The sandwich panels use lightweight cores and embedded stiffeners. The rails are designed to enable rotational assembly that compresses adhesive beads for robust connections. The floor is made from modular extruded panels with staggered seams and integrated tracks, and a removable closeout cover is provided for access to wiring and electronics. The design of the system supports both strong mechanical attachment and efficient manufacturing, while reducing overall vehicle weight and assembly time. The system helps maintain structural integrity under safety testing conditions.

Abstract: A vehicle flooring system for converting regular vehicles into wheelchair accessible vehicles. The flooring system is made up of individual flooring panels connected via a snap fit type tongue and lip connection. Each individual panel contains an integral track. The integral track forms a positive lock with the track channels. The flooring system is able to satisfy government regulations concerning seat and wheelchair location pull testing.

Abstract: A housing assembly can include a housing structure and a plurality of leg members. At least one leg member of the plurality of leg members comprises a foot portion and at least one connecting portion. The at least one leg member can define a first concave portion disposed between the foot portion and a first convex portion, and the first convex portion is disposed between the first concave portion and a second concave portion. A radius of the first concave portion can be equal to a radius of the first convex portion.

Abstract: A vehicle flooring system configured to enable movement of cargo within a vehicle. The flooring system is made up of individual flooring panels connected via a snap fit type connection. In one embodiment, the flooring panels define one or more openings/slots configured to receive and secure one or more rollers. The rollers are configured to enable slidable movement of cargo within the vehicle. In another embodiment, the flooring panels include one or more lightweight panels and one or more reinforced panels. In one example, the reinforced panels are metal, such as extruded aluminum. In another example, the lightweight panels are a polymeric material, such as extruded plastic. The flooring system is further configured to satisfy government regulations concerning pull testing.
