Abstract
A plastic monocoque body assembly comprised of three pieces bonded toegther is provided for a lawn and garden-type vehicle. The body assembly incorporates hollow compartments to provide the frame-like strength necessary to withstand concentrated torsional and bending loads. Compartments are provided in the sides, center and front portions of the assembly with each compartment including walls comprised of at lest two of the three pieces which form the assembly.
Claims14
A monocoque vehicle assembly comprised of a thin-walled, plastic upper member joined to a thin-walled, plastic lower member, said assembly including at least three multi-sided closed sectioned compartments formed by and between said members for improving structural stiffness or rigidity of the assembly as it encounters torsional and bending loads, the first and second enclosures being provided to each transverse side of a centrally positioned operator station, and the third enclosure provided in the center portion of said vehicle vertically below the operator station.
A ride-on vehicle having thin-walled plastic upper and lower members joined together in a monocoque assembly, said assembly including first and second portions adapted to support respectively the torso and feet of an operator,
- the upper member including at least first and second pairs of laterally and downwardly extending structure which are joined with at least first and second pairs of lateral and upwardly extending member structures to form first and second closed section compartments for resisting torsional and bending loads encountered by the assembly.
A monocoque vehicle assembly including an upper member fixed to a lower member, said members being made from plastic material and forming central and forward vehicle portions, the central portion adapted to receive the torso of an operator and the forward portion adapted to receive the feet of said operator,
- the upper and lower members further forming between them at least three hollow compartments adapted to resist torsional and bending loads encountered by the vehicle, two of said compartments being located on the lateral sides of the central portion of the assembly and one compartment being located within the forward portion of the assembly.
