Abstract:
A rolling foot-power assembly comprising:a. a stationary assembly supported for movement on at least one roller; b. a first movable assembly and a second movable assembly, said first movable assembly and second movable assembly each being supported in mounted relation on said stationary assembly so as to be selectively movable in a power stroke manner and in a retraction manner, said first movable assembly and said second movable assembly each being movable in the power stroke manner between a power stroke start position and a power stroke end position by virtue of a force being imparted to the respective movable assembly, said force being imparted to said first and second movable assemblies being derived from a combination of the gravitational force impartable by a human body and the dynamic thrust impartable by the human foot, and said first movable assembly and said second movable assembly each being movable in the retraction manner to thereby dispose the respective movable assembly again at its power stroke start position in readiness for a repeat movement of the respective movable assembly in the power stroke manner; c. a retraction mechanism operatively connected to said first movable assembly and said second movable assembly for alternately moving said first movable assembly in the retraction manner in response to movement of said second movable assembly in the power stroke manner and moving said second movable assembly in the retraction manner in response to movement of said first movable assembly in the power stroke manner; and d. a motion-conversion mechanism operatively connecting both the roller and said first and second movable assemblies for translating movement of the respective movable assembly moving in the power stroke manner into a rotation of the roller, said motion-conversion mechanism translating a predetermined unit of force applied thereto by said first movable assembly and said second movable assembly into a corresponding increment of rotation of the roller, and said first movable assembly and said second movable assembly each being directly connected to said motion-conversion mechanism such that, with respect to the movement in the power stroke manner of said first movable assembly and said second movable assembly, the same corresponding increment of rotation of the rollers is produced for each predetermined unit of force applied by the respective one of said first and second movable assemblies to said motion-conversion mechanism throughout the movement in the power stroke manner of the respective one of said first and second movable assemblies from its power stroke start position to its power stroke end position.
