Composite under body structure
A system for supporting the bed of a utility vehicle, the system adapted to be mounted on the underbody frame of the utility vehicle, the system comprising: a generally planar unitary support formed from a composite material, the support having a first surface and a second vertically offset surface; a plurality of connecting members extending from the first surface to the offset surface, the members providing strength to said support; a generally rectangular panel fabricated from a composite material, the panel adhesively attached to said offset surface, the panel adapted to serve as a loading surface for the bed of the utility vehicle; a bracket secured to the support for mounting the support to the frame of the utility vehicle; and a backing plate secured to the support, wherein the plate and the bracket sandwich the support to secure it to the frame of the vehicle.
1. A bed assembly securable to the frame of a utility vehicle comprising:
an understructure formed from a fiber reinforced resin composite material and having a plurality of ridges each formed from a ridge wall extending between a first surface and a second vertically offset surface and which provides strength to said understructure, said understructure adapted to be mounted to the frame of a utility vehicle; said understructure having first and second side edges extending generally in parallel alignment and wherein at least portions of the ridge walls of at least two of the ridges extend diagonally relative to said first and second side edges and form an X-shape;
a panel secured over said understructure, adapted to serve as a loading surface for the vehicle; and
a bracket secured to said understructure for securing said understructure to the frame of the utility vehicle.
2. The bed assembly as in claim 1 wherein said offset surface of said understructure includes a cut-out portion.
3. The bed assembly as in claim 1 wherein said bracket is adapted to be spring-bolted to the frame of the utility vehicle.
4. A system for supporting the bed of a utility vehicle, said system adapted to be mounted on the underbody frame of the utility vehicle, said system comprising:
a generally planar unitary support formed from a composite material, said support having a first surface and a second vertically offset surface;
a plurality of connecting members extending from said first surface to said offset surface, said members providing strength to said support;
a panel fabricated from a composite material, said panel adhesively attached to said offset surface, said panel adapted to serve as a loading surface for the bed of the utility vehicle;
a bracket secured to said support for mounting said support to the frame of the utility vehicle; and
a backing plate secured to said support, wherein said plate and said bracket sandwich said support to secure it to the frame of the vehicle.
5. The system for supporting the bed of a utility vehicle as in claim 4 wherein said offset surface of said support includes a cut-out portion.
6. The system for supporting the bed of a utility vehicle as in claim 4 wherein said bracket is adapted to be spring-bolted to the frame of the utility vehicle.
7. The bed assembly as in claim 1 further comprising first and second utility compartments secured on opposite sides of said panel.
