Abstract:
1. A folding hand truck having storage and operative positions comprising: a. a middle frame having an upper end, a lower end, a front side, and a back side, further comprising a left tube and a right tube, with each of said left tube and said right tube having an upper end and a lower end; b. an upper frame having an upper end, a lower end, a front side, and a back side, further comprising an inverted U-shaped tube having a left end and a right end, wherein said lower end of said upper frame is rotatably connected to said upper end of said middle frame, with locking means for locking said lower end of said upper frame to said upper end of said middle frame; c. a lower frame having an upper end, a lower end, a front side, and a back side, further comprising a left tube and a right tube, with each of said left tube and said right tube having an upper end and a lower end, wherein said upper end of said lower frame is rotatably connected to said lower end of said middle frame by hinge means, with locking means for locking the upper end of said lower frame to the lower end of said middle frame; d. a platform, having a rear edge, rotatably connected to said lower end of said lower frame by hinge means such that in the operative position, said rear edge of said platform extends below said lower end of said lower frame to said rear side of said lower frame; and e. a dual wheel assembly further comprising a left wheel and a right wheel, with each of said wheels being rotatably connected at its center to said lower frame by means for folding said wheels from a position wherein the plane of each of said wheels is parallel with said lower frame to a position wherein said plane of said wheels are parallel to each other and are perpendicular to the plane of said lower frame; f. wherein said means for locking said lower end of said upper frame to said upper end of said middle frame and said means for locking said upper end of said lower frame to said lower end of said middle frame comprise locking pins; g. wherein said left end of said upper frame aligns coaxially with said upper end of said left tube of said middle frame, and said right end of said upper frame aligns coaxially with said upper end of said right tube of said middle frame when said folding hand truck is in the operative position; h. wherein said lower end of said left tube of said middle frame aligns coaxially with said upper end of said left tube of said lower frame, and said lower end of said right tube of said middle frame aligns coaxially with said upper end of said right tube of said lower frame when said folding hand truck is in the operative position; and i. wherein said locking pins are mounted within and slide within said ends of said tubes such that:
