Abstract
Abstract A stationary exercise machine for simulating standup jogging or running-type exercise wherein a pedal-type mechanism is swivelly supported on a vertical axis and has pedal platforms heavily weighted to impart an oscillatory twisting or side-to-side movement to the crank mechanism upon operation. Adjustable return-to-center spring means controls the amplitude and uniformity of the twisting motion to suit the requirements of the operator. Center of gravity of pedal weight is located well below the pedal platform axis so that the pedal platforms will seek horizontal or level rest positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
An exercise machine comprising, in combination, a base support member, a pedal crank member having a central journal pin portion and a pair of relatively offset, opposed, outwardly extending journal stud portions, a platform foot pedal journaled on each of said journal stud portions, a journal pin bearing member journaling said central journal pin portion about a horizontal axis, pedal support mechanism fixed to said support base member and journaling said bearing member about a vertical axis centrally located between said journal Stud portions, and means acting between said base member and said pedal support mechanism for yieldingly constraining said pedal crank member in a predetermined centered position with respect to said base support member.
Claim 2
Dependent Claim
115 words
An exercise machine comprising, in combination, a base support member, a pedal crank member having a central journal pin portion and a pair of relatively offset, opposed, outwardly extending journal stud portions, a platform foot pedal journaled on each of said journal stud portions, a journal pin bearing member journaling said central journal pin portion about a horizontal axis, pedal support mechanism fixed to said support base member and journaling said bearing member about a vertical axis centrally located between said journal Stud portions, and means acting between said base member and said pedal support mechanism for yieldingly constraining said pedal crank member in a predetermined centered position with respect to said base support member.
Claim 3
Dependent Claim
45 words
An exercise machine as defined in claim 1 wherein said platform foot pedals are of heavy construction with weight so pendulously distributed as to effect centers of gravity well below their respective journaling axes, thereby to introduce flywheel and torque effects upon pedaling the machine.
Claim 4
Dependent Claim
43 words
An exercise machine as defined in claim 2 including handle means extending upwardly of the forward end of said base support member and providing a pair of laterally opposed handle grips for steadying the body during use of the machine by an exerciser.
Claim 5
Dependent Claim
58 words
An exercise machine as defined in claim 1 wherein said pedal support member comprises a vertical pivot post fixed with respect to said base support member and extending vertically upwardly thereof, and a sleeve bearing member rotatably journaled on said pivot post, said journal pin bearing member being secured to the upper end of said sleeve bearing member.
Claim 6
Dependent Claim
32 words
An exercise machine as defined in claim 4 wherein the upper end of said vertical pivot post is in abutment with said journal pin bearing member to form a thrust bearing therewith.
Claim 7
Dependent Claim
65 words
An exercise machine as defined in claim 4 wherein said pedal crank member constraining means comprises a forwardly extending arm fixed at one end with respect to the lower end portion of said sleeve bearing member and a tension spring secured at one end to an outer end portion of said arm and secured at its other end with respect to said base support member.
Claim 8
Dependent Claim
43 words
An exercise machine as defined in claim 6 including handle means extending upwardly of the forward end of said base support member and providing a pair of laterally opposed handle grips for steadying the body during use of the machine by an exerciser.
