ABSTRACT:
In accordance with an illustrative embodiment of the present invention, a motion converting mechanism for an exercise machine includes a shaft mounted on spaced bearings on opposite walls of a side compartment of the machine, a pitman arm on the shaft, a drive assembly including inner and outer arms extending above and below the shaft, a linkage and transducer that connect the outer end of the pitman arm to the lower end of the drive assembly, a lifting wheel on the shaft between the inner and outer drive arms, and a laterally shiftable pin that extends through the outer drive arm, one of a plurality of holes near the outer periphery of the lifting wheel and into the inner arm to connect the drive assembly to the lifting wheel in any one of a plurality of relative orientations. A stop against pivotal rotation of the lifting wheel also is provided to enable static tests to be made of certain ones of the users muscles.
