Abstract
Abstract A wheeled base is provided having front and rear ends with an occupant seat disposed on the rear end and an upright having its lower end supported from the front end of the base. A mount is supported from an upper portion of the upright for oscillation about a horizontal transverse axis and the mount extends laterally outwardly on opposite sides of the upright. A pair of spring biased levers are pivotally supported, intermediate their opposite ends from the opposite side portions of the mount for angular displacement about generally parallel axes normal to the axis of oscillation of the mount and an expansion spring is connected between the forward ends of the levers yieldingly biasing the forward ends together and the rear ends of the levers, which are disposed adjacent the seat, apart. Further, a pedal crank assembly is journaled for rotation about a horizontal axis beneath the mount from which the forced levers are supported and the pedal crank assembly is adjustable vertically as well as toward and away from the occupant''s seat.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
172 words
An exercising apparatus comprising a base including operator''s position defining means, an upright supported at its lower end from said base, a mount supported from an upper portion of said upright for oscillation relative thereto about a horizontal transverse axis, a pair of force levers pivotally supported intermediate their opposite ends from said mount and on opposite sides of said upright for oscillation about generally parallel axes disposed substantially normal to said axis, mEans connected between said levers yeildingly biasing one pair of corresponding ends thereof away from each other, said one pair of ends including hand grip means adapted to be gripped by the hands of the user of said apparatus, and a pedal crank assembly journaled for rotation about a second horizontal axis generally paralleling the first mentioned axis and including pedal cranks whose free ends are adapted to be engaged by the feet of said user, said pedal crank assembly being generally centered between parallel upstanding planes containing the axes of oscillation of said levers relative to said mount.
Claim 2
Dependent Claim
172 words
An exercising apparatus comprising a base including operator''s position defining means, an upright supported at its lower end from said base, a mount supported from an upper portion of said upright for oscillation relative thereto about a horizontal transverse axis, a pair of force levers pivotally supported intermediate their opposite ends from said mount and on opposite sides of said upright for oscillation about generally parallel axes disposed substantially normal to said axis, mEans connected between said levers yeildingly biasing one pair of corresponding ends thereof away from each other, said one pair of ends including hand grip means adapted to be gripped by the hands of the user of said apparatus, and a pedal crank assembly journaled for rotation about a second horizontal axis generally paralleling the first mentioned axis and including pedal cranks whose free ends are adapted to be engaged by the feet of said user, said pedal crank assembly being generally centered between parallel upstanding planes containing the axes of oscillation of said levers relative to said mount.
Claim 3
Dependent Claim
