The present invention relates to exercise machines, and more particularly to an exercise machine with adjustable pedals that has pedals adjustable to each other, users can adjust pedal locations according to their height and body width, and then the objectives of easy using and increasing exercise comfort would be attained.

BACKGROUND OF THE INVENTION

A conventional exercise machine, e.g. walking exercise machine or elliptical exercise machine, is equipped with two pedals that can move back and forth, on which users can stand and do exercise. Conventional pedal mechanism includes a pedal frame 40 and a pedal 41 installed on top of the pedal frame 40, the conventional pedals 41 are adjustable in slant angles relative to the pedal frames 40 to cooperate with the changing of exercising attitude in users' feet, yet unable to be adjusted in relative pedal locations per users' body height and width, such as, the distance of the two pedals 41. In other words, conventional pedals 41 are pivotally installed on pedal frames 40, such that the pedals 41 are capable of being turned relatively to the pedal frames 40, yet unable to be moved against, such as TW Pat. No. M290759 as shown in FIG. 7 and TW Pat. No. M576236 as shown in FIG. 8.

As per the shortcomings that the above mentioned conventional exercise machines have, it is learned that the pedals of exercise machines require the function of being adjusted in locations per users' body height and width, the owner of this invention devoted himself to design and development, and with efforts on design and try-out, the design and development result in this invention.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a pedal mechanism for an exercise machine with function of adjusting pedal locations that users can adjust relative locations of the two pedals per their body heights and widths to satisfy themselves with comfort in exercising.

Concrete structure for attaining the above mentioned objective includes a mechanical body and two pedal arms connected to the mechanical body, each pedal arm has one pedal frame and one pedal that is installed on top of the pedal frame. Each pedal frame is equipped with at least one guide member, and each pedal has one slide member that fits into the guide member. One actuating member is installed in-between the pedal frame and the pedal, the actuating member has two force transfer ends that are installed on the pedal frame and the pedal each, one of the force transfer ends is an adjusting threaded rod that allows no moving but turning, and the other is a threaded nut with a nut hole for the adjusting threaded rod to be fitted into. When the adjusting threaded rod is turned, the threaded nut will give reacting force to move the pedal against the pedal frame.
