1. A utility trailer configured to be towed behind a vehicle that facilitates alteration between an open configuration and a compact configuration comprising:
a center trailer section comprising:
a rigid rectangular center frame chassis;a center bed floor disposed on said front frame;a wheeled axle and suspension system supporting said center frame; and,a pair of collapsible center side barriers pivotally attached to opposing lateral sides of said center frame such that said center side barriers may maintain a normal orientation to said center bed floor in an open configuration, and fold approximately parallel to, and stacked upon, said center bed floor in a compact configuration; a front trailer section comprising:
a rigid rectangular front frame chassis;a front bed floor disposed on said front frame;a pair of collapsible front side barriers pivotally attached to opposing lateral sides of said front frame such that said center side barriers may maintain a normal orientation to said front bed floor in an open configuration, and fold approximately parallel to, and stacked upon, said front bed floor in a compact configuration; and,a collapsible front end barrier pivotally attached to the front portion of said front frame such that said front end barrier may maintain a normal orientation or a parallel orientation extending forward of said front bed floor in an open configuration, and fold approximately parallel to, and stacked upon, said front side barriers in a compact configuration;a rear trailer section comprising:a rigid rectangular rear frame chassis;a rear bed floor disposed on said rear frame;a pair of collapsible rear side barriers pivotally attached to opposing lateral sides of said rear frame such that said rear side barriers may maintain a normal orientation to said rear bed floor in an open configuration, and fold approximately parallel to, and stacked upon, said rear bed floor in a compact configuration; and,a collapsible rear end barrier pivotally attached to the rear portion of said rear frame such that said rear end barrier may maintain a normal orientation or a parallel orientation extending rearward of said rear bed floor in an open configuration, and fold approximately parallel to, and stacked upon, said rear side barriers in a compact configuration; a tongue that facilitates connection between said center trailer section and said vehicle; a rearward offset hinge mechanism comprising two offset braces joined by a rear pivot, that pivotally joins said center trailer section and said rear trailer section such that the pivot point of said junction is offset above said center bed floor by a distance of half the combined thickness of said collapsed center side barrier, said collapsed rear side barrier, said rear end barrier, combined with said rear pivot diameter, thereby allowing said rear trailer section to stack directly upon said collapsed center trailer section thereby minimizing the overall stack height of said center and said rear trailer sections; and, a forward offset hinge mechanism comprising two forward offset braces joined by a forward pivot, that pivotally joins said center trailer section and said front trailer section such that the pivot point of said junction is offset above said center bed floor by a distance of half the combined thickness of said collapsed center side barrier, said collapsed rear side barrier, said rear end barrier and said rear trailer section, combined with said forward pivot diameter, thereby allowing said front trailer section to stack directly upon said collapsed rear trailer section when it is stacked directly upon said center trailer section thereby minimizing the overall stack height of said center, said rear and said front trailer sections. |
