Abstract:
1. A hand truck comprising: an upright load bearing frame of fixed geometry having a front side, a load plate rigidly fixed to said load bearing frame at said front side, a rear side, and two carriage wheels rotatably mounted to said load bearing frame at said rear side at a fixed point on said load bearing frame, said carriage wheels having an axis of rotation about an axle therebetween, a load shifting lever, said load shifting lever disposed to move the center of gravity of said load bearing frame, said load shifting lever comprising a retracting lever member rotatably mounted to said axle at a fixed point spaced apart from said carriage wheels, and a load shifting assembly stop positioned on a rear portion of said load plate, said stop adapted to limit the degree of rotation of said load shifting lever about said axle; a lower end of said retracting lever member positioned to directly contact said stop when an upper end of said load shifting lever is pulled from a retracted position by a user, thereby causing said load plate and the load bearing frame to tilt and moving the center of gravity of said load bearing frame.
