US Patent 7100970 Flooring system for vehicle

A cargo-carrying vehicle has a plurality of flooring members. A pair of parallel, spaced-apart frame rails confines the flooring members therebetween in closely spaced adjacent relation to form a floor surface. A pair of end members extends transversely between the frame rails at the ends thereof to secure the frame members against movement parallel to the frame rails. At least one of the end members is selectively moveable relative to the frame rails to permit selective removal of one or more of the flooring members from between the frame rails.
