<p>A hand truck having ground engaging members which tilt the hand truck under conditions of greater leverage than that available by grasping the frame of the hand truck (10). The ground engaging members (32, 34) are journaled to the frame (12) of the hand truck (10). In one embodiment, the ground engaging members (32, 34) assume the entire weight of the loaded hand truck (10). In another embodiment, the ground engaging members (132, 134) push the front end of the hand truck (10) upwardly, employing the wheels (126) as a fulcrum. In the second embodiment, the wheels (126) remain in contact with the ground. In the first embodiment, the ground engaging members (32, 34) serve also as a fulcrum, allowing the wheels to be elevated off the ground. In both embodiments, the ground engaging members (32, 34) are powered either by a foot operated lever (46) or a hand operated lever (246).</p> |
