A collapsible trailer/ramp assembly is provided which is formed by a pair of deck plates that are interconnected by a hinge along the longitudinal centerline of the deck. The downturned side and end edges of the plates and a plurality of longitudinal and transverse structural members provide the trailer or ramp structure with efficient structural integrity. These structural members also function to define a storage receptacle which is adapted to receive the drawbar structure, wheel assemblies, transverse structural bridge plates and locking pins of the trailer/ramp assembly. When the deck sections are folded the storage receptacle is completely closed to thereby prevent loss of any of the stored components of the trailer/ramp assembly. All of the component parts are assembled to the deck sections by means of manually insertible and removable pins so that tools and other equipment are not required for assembly and disassembly procedures. With the wheel assemblies and drawbar assemblies removed from the unfolded deck sections, the deck sections form a unique ramp that can be efficiently used for loading and unloading operations.

A collapsible trailer/ramp assembly comprising: (a) a pair of generally rectangular deck plates having a plurality of end and side flanges extending downwardly therefrom and a plurality of structural members including transverse members extending downwardly from the under side thereof and cooperating with said deck plates to form a pair of deck sections of efficient structural integrity, two of said side flanges of said deck plates being pivotally interconnected by hinge member at the lower portions thereof and forming a longitudinal pivot axis forming a longitudinal centerline of said trailer/ramp assembly and permitting said deck sections to form a compartmentalized box-like enclosure when folded about said longitudinal pivot axis, said deck sections when unfolded to substantially coextensive relation, forming a ramp for supporting objects moving thereon, said structural members defining opposed walls disposed in normal relation with said deck plates and forming wheel receptacle means and cooperating in the folded condition of said deck sections to form storage receptacle means for trailer parts, said opposed walls having pin receiving apertures formed therein; (b) a pair of wheel assemblies each having a bifurcated wheel support providing wheel support legs supporting an axle and wheel and having close fitting relation between said opposed walls and thus being removably received in substantially immovable relation by said wheel receptacle means; (c) a plurality of transverse structural bridge members being removably secured in assembly with said transverse members of said deck sections at spaced locations along the length thereof and in transverse relation to said longitudinal centerline and securing said deck sections to prevent folding thereof; (d) drawbar means being removably received by said deck sections in parallel relation with said longitudinal centerline and providing hitch receiving means for connection to the trailer hitch of a tow vehicle; and (e) a plurality of locking pins releasably securing said wheel assemblies, said transverse structural bridge members and said drawbar means to said deck sections.
