ABSTRACT:
The trailer of this invention comprises a plurality of readily foldable or separable components to provide a full width trailer for hauling conventional goods or a narrow trailer for special hauling purposes or for storage in a limited space. In addition it may be readily dismantled into a group of relatively small components which may be packed in a vehicle trunk or in a small storage space. In one form it includes two side frames with upstanding side boards, a leaf spring detachably connected under each side frame, and a wheel carrying stub axle fixedly connected to the spring. Cross braces connect the two frames and a cross-axle assembly of variable effective length connects the two stub axles. Fore and aft floor boards are hingedly connected to the frames and to each other, and one or more may be folded to define a narrower trailer on occasion. The trailer may be dismantled into the components mentioned for storage or transport.
