Patent number: 6095531Abstract: An improved hand truck apparatus for use in moving loads up and down stair which includes a pair of novel stair tread engaging assemblies which operate smoothly and in a relatively friction-free manner. The stair engaging belts of each of the stair tread engaging assemblies is supported by a plurality of freely rotating, spaced-apart rollers which are grooved to closely receive and support the lower portion of the belts in the manner to positively guide the belts around the belt supporting frames of the assemblies as the rollers freely rotate about their individual axles. The roller supporting frame of each of the stair tread engaging assemblies is uniquely provided with guide means for guiding the stair tread engaging belts into the channels formed in the rollers and for preventing undesirable frictional contact between the belt and the supporting frame as the belt travels about the supporting rollers.Type: GrantFiled: March 17, 1998Date of Patent: August 1, 2000Assignee: Olympia industrial, Inc.Inventor: Zareh Khachatoorian
