Patent attributes
The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Elliptical cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical cross trainers often use excessive pedal articulation which can overwork the ankle to achieve a longer stride. The present invention is an improved elliptical exercise machine capable of extended exercise with less pedal articulation that is more ankle friendly. One end of a foot support member is guided by a guide link for back and forth movement while the other end is guided by a drive link with cam guide to drive an alternator and flywheel. The resulting pedal motion-is foot friendly. Stride length can be adjusted. Handles are coordinated with the foot support members for arm exercise.
