Abstract

An elliptical exercise apparatus includes an upstanding support connected to a front end of a base support, a rail assembly provided on a rear end of the base support, a wheel assembly mounted on the front end of the base support, a swing rod connected pivotally to the upstanding support, a slide rod having a rear end slidable forwardly and rearwardly along the rail assembly and a front end connected pivotally to the wheel assembly, a pedal seat connected pivotally to the slide rod, a pedal member mounted slidably on the pedal seat, a first link rod having a front end connected pivotally to the swing rod and a rear end connected pivotally to the pedal seat, and a second link rod having a front end connected pivotally to the swing rod below the first link rod and a rear end fixed to the pedal member.

Claims

1. An elliptical exercise apparatus comprising:

a main frame including a base support adapted to be supported on a supporting surface and having front and rear ends, an upstanding support connected to said front end of said base support, and a rail assembly provided on said rear end of said base support;

a wheel assembly mounted on said front end of said base support, and including a crank member;

a swing rod connected pivotally to said upstanding support and having a bottom section;

a slide rod having a rear end slidable forwardly and rearwardly along said rail assembly, and a front end connected pivotally to said crank member;

a pedal seat connected pivotally to said slide rod;

a pedal member mounted slidably on said pedal seat; and

a link unit including a first link rod having a front end connected pivotally to said bottom section of said swing rod and a rear end connected pivotally to said pedal seat, and a second link rod having a front end connected pivotally to said bottom section of said swing rod below said front end of said first link rod and a rear end fixed to said pedal member.

2. The elliptical exercise apparatus of claim 1, wherein said pedal seat includes a pedal support connected pivotally to said slide rod, and a pedal rail fixed to said pedal support and having two opposite lateral sides formed respectively with slide grooves.

3. The elliptical exercise apparatus of claim 2, wherein said pedal member includes an inverted U-shaped slide plate having two opposite side plates, a pedal plate fixed on top of said slide plate, and a plurality of rollers mounted respectively on inner faces of said side plates and received slidably and correspondingly in said slide grooves.

4. The elliptical exercise apparatus of claim 1, wherein said swing rod further includes a grip section extending upwardly from said bottom section, and a pivot section between said grip section and said bottom section and connected pivotally to said upstanding support.
