Abstract
Abstract A user''s legs and lower torso are strenuously exercised by the continuous oscillatory movement of foot-supporting platforms on which the subject stands while grasping a hand rail for stability and safety. The foot-supporting platforms are carried on and movable with an oscillating main turntable which is supported above a stationary base carrying the power drive for the oscillating components. The machine is useful in rehabilitating stroke or other paralytic victims. The foot-supporting platforms are oscillate in unison relative to the turntable while the turntable is oscillated relative to the base.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
An exercising machine comprising a base, a vertical axis horizontal turntable journaled on said base for oscillatory movement, a pair of spaced horizontal vertical axis footrest platforms journaled on said turntable for independent rotation relative thereto, and power drive means connected with the turntable and said footrest platforms and causing the latter to oscillate in unison relative to the turntable while the turntable is oscillated relative to said base, said power drive means comprising a drive motor on said base, a vertical axis crank shaft coupled to the drive motor anD driven thereby and having a pair of opposing eccentrics, and an adjustable drive linkage coupled with said turntable and said footrest platforms and including a pair of rods coupled to said crank shaft eccentrics and operated thereby in an out-of-phase mode.
Claim 2
Dependent Claim
132 words
An exercising machine comprising a base, a vertical axis horizontal turntable journaled on said base for oscillatory movement, a pair of spaced horizontal vertical axis footrest platforms journaled on said turntable for independent rotation relative thereto, and power drive means connected with the turntable and said footrest platforms and causing the latter to oscillate in unison relative to the turntable while the turntable is oscillated relative to said base, said power drive means comprising a drive motor on said base, a vertical axis crank shaft coupled to the drive motor anD driven thereby and having a pair of opposing eccentrics, and an adjustable drive linkage coupled with said turntable and said footrest platforms and including a pair of rods coupled to said crank shaft eccentrics and operated thereby in an out-of-phase mode.
Claim 3
Dependent Claim
78 words
An exercising machine as defined by claim 1, and upstanding support shafts for said turntable and foot rest platforms, said linkage including crank arms on each of said shafts, an intermediate linkage portion connecting the crank arms on the shafts of the foot rest platforms, one rod of said pair of rods coupled to the intermediate linkage portion and the other rod of the pair of rods coupled to the crank arm on the shaft of the turntable.
Claim 4
Dependent Claim
68 words
An exercising machine as defined by claim 2, and said intermediate linkage portion comprising a bell crank freely rotatably mounted on the shaft of the turntable, a tie rod means interconnecting the crank arms on the shafts of the foot rest platforms and being connected to one arm of said bell crank, and the other arm of said bell crank coupled to said one rod of said pair.
Claim 5
Dependent Claim
29 words
An exercising machine as defined by claim 3, and each arm of said bell crank and each of said crank arms having a series of adjustment openings formed therein.
Claim 6
Dependent Claim
125 words
A machine for exercising the legs and lower torso of a standing subject comprising a relatively stationary base, an elevated hand rail on the base at a convenient height to be grasped by a standing subject, a substantially horizontal oscillatory turntable on the base, a pair of laterally spaced oscillatory footrest platforms bodily mounted on the turntable and movable with the turntable during oscillation of the latter, and power drive means common to said turntable and footrest platforms and operatively coupled with the turntable and footrest platforms in such a way that the power drive means simultaneously causes oscillation of the turntable and simultaneous oscillation of the footrest platforms on and relative to the turntable while the footrest platforms are moving bodily with the turntable.
Claim 7
Dependent Claim
125 words
A machine for exercising the legs and lower torso of a standing subject comprising a relatively stationary base, an elevated hand rail on the base at a convenient height to be grasped by a standing subject, a substantially horizontal oscillatory turntable on the base, a pair of laterally spaced oscillatory footrest platforms bodily mounted on the turntable and movable with the turntable during oscillation of the latter, and power drive means common to said turntable and footrest platforms and operatively coupled with the turntable and footrest platforms in such a way that the power drive means simultaneously causes oscillation of the turntable and simultaneous oscillation of the footrest platforms on and relative to the turntable while the footrest platforms are moving bodily with the turntable.
Claim 8
Dependent Claim
36 words
A machine as defined in claim 5, and said turntable and footrest platforms spaced somewhat above said base, and said power drive means for the turntable and footrest platforms mounted on the base below said turntable.
