Abstract

An exercise machine comprising an elongate slide platform with a mount slidingly secured thereon, a footrest rotatably secured to the top of the mount, a base bar with one end thereof secured to the slide platform under the central portion thereof, a vertical post with the lower end thereof secured to the opposite end of the base bar, a pair of foldable pedal bars pivotably secured to respective lateral sides of the vertical post near the lower end thereof, and a pair of handles extending from respective lateral sides of the vertical post near the upper end thereof. The mount and the pedal bars are connected with resistance elements that resist the respective sliding and pivoting motions thereof. Resistance elements also resist the rotational motion of the footrest. Whereby, with hands gripping the handle bars and feet resting on the footrest a user can exercise various parts of his or her body by sliding the footrest to and fro along the platform or rotating the footrest in opposite directions about the mount, or with feet on the pedals, by pedaling up and down in stairclimbing fashion.

Dependent claims

A floor mounted exercise machine comprising:

an elongate slide platform;
a mount slidingly secured to said slide platform;
a footrest rotatably secured to said slide platform;
a base bar with one end thereof secured to the central portion of said slide platform;
a pair of pedal bars, with one end of each said pedal bar pivotably secured to a respective lateral side of a vertical post on a lower portion thereof and the other end of each said pedal bars extended towards said slide platform;
a pair of handle bars extending outwardly from respective lateral sides of said vertical post in proximity to the upper end thereof;
a first resistance means, engaged with said mount, for resisting the sliding motion of said mount along said slide platform in a predetermined manner;
a second resistance means, engaged with said pedal bars, for resisting the pivoting motion of said pedal bars in a predetermined manner;
whereby, a user, with hands grasping respective said handle bars and feet resting on said footrest, can exercise various parts of his or her body by repeatedly sliding said footrest and said mount to and fro along said slide platform;
or
by repeatedly rotating said footrest first in one direction and then in the other direction;
or
with feet resting against respective said pedal bars, by repeatedly stepping down on alternate said pedal bars in stair climbing fashion.
