Towable unified floor frame assembly
First Claim
1. A readily towable wide unified floor frame assembly, comprising:
- two elongate load-supporting outer beams disposed parallel to a longitudinal axis of said floor frame assembly, each of said beams having respective front and rear ends;
front and rear end wood I-beam members respectively connected perpendicular to said axis at said front and rear ends of said outer beams, defining therewith a perimeter of said floor frame assembly, said perimeter having substantially vertical inner and outer perimeter surfaces substantially defined by corresponding inner and outer surfaces of said outer beams and said end members;
a plurality of first wood I-beams normal to said outer beams and connected to said inner perimeter surface, said first wood I-beams being disposed at predetermined locations inwardly of said front and rear ends of said outer beams so as to define therebetween a region for accommodating a plurality of wheels for supporting said frame assembly during towing thereof;
a pair of inner wood beams symmetrically disposed in said wheel accommodating region parallel to said longitudinal axis and connected at their respective ends to a correspondingly located pair of said first wood I-beams, said inner wood beams being provided along a bottom edge thereof with wheel attachment brackets;
a plurality of second wood I-beams normal to said outer beams and respectively connected to said inner perimeter surface inside said wheel-accommodating region, said second wood I-beams each being formed with a plurality of vertical first gaps extending across a lower flange into a web thereof and disposed symmetrically about said axis, each of said gaps being of a width and height sufficient to closely accommodate a corresponding one of said inner wood I-beams therewithin;
a plurality of third wood I-beams interspersed with said second wood I-beams, normal to said outer beams and respectively connected to said inner perimeter surface inside said wheel accommodating region, said third wood I-beams each being formed with a plurality of vertical second gaps extending across a lower flange into a web thereof and disposed symmetrically about said axis, each of said gaps being of a width and height sufficient to accommodate said wheels, whereby upper portions of said wheels are partially contained within said second gaps and said floor frame assembly when said wheels are attached to and support said floor frame assembly;
a floor mounted atop and to said outer beams, said front and rear end members, and said first, second and third wood I-beams; and
hitch means securely attachable to and readily detachable from a front end of the floor frame assembly for applying a towing force thereat.

Abstract
A unified floor frame assembly has two elongate outer load-supporting beams formed of wooden elongate beam sections that may be selected to have different vertical cross-sectional dimensions and, optionally with two thicknesses united, are butt-spliced to be cambered in parallel vertical planes to counter forces that may tend to cause sagging of the floor frame assembly during transportation. A wheel carrier assembly is detachably mountable thereto with a plurality of wheels partially recessed within the floor frame assembly and a towing hitch assembly is attachable to a forward end of the floor frame assembly for applying a towing force thereat. Wooden I-beams are used as transverse frame members to provide lightweight strength and floor frame widths of the order of 18 ft. to 20 ft. A moisture, dirt, insect and pest excluding thin covering is provided underneath the floor frame assembly, and sections of heating and ventilating ducting, piping, wiring and the like are includable during manufacture of the floor frame assembly. Individual floor frame assemblies may be supported at their permanent location underneath the periphery or, where two such floor frame assemblies are to be coupled to obtain a larger size floor, central elongate beams may be supported by metal posts. Upon delivery of the floor frame assembly to its intended location, the wheel carrier assembly and the towing hitch assembly are both detached and removed therefrom for reuse.
