    Abstract: A collapsible hand truck (10) having storage and operative positions. The truck includes a back frame (12) having a back side, an upper end (16) and a lower end (18). Two wheels (44) are rotatably connected to the back frame lower end (18) at a position offset rearwardly and downwardly therefrom. The offset position is created by aft-extending arms (40). The truck (10) further includes a bail (14) having a front end (20) and an aft end (22). The aft end (22) is rotatably connected to the back frame lower end (18). A strap (50) is provided for maintaining the maximum angular distance between the back frame (14) and the bail (12) during use. In the operative position, the bail (14) is located substantially forward of the back frame (12) and the strap (50) is interconnected between the bail front end (20) and the back frame upper end (16). To reach the storage position, the bail (14) rotates downward and aftward to a location behind the back frame (12) and substantially adjacent to the back frame back side.
