ABSTRACT:
A walk simulating machine includes two pedal connect rods, a horizontal rod, two side connect rods consisting of an upper and a lower connect rod, and a stop member in front of each upper connect rod. The lower connect rods sway together with the pedal connect rods. The upper and the lower connect rods sway straight if the upper connect rods not stopped by the stop member; the lower connect rods solely sway if the upper connect rods stopped. So the walking orbit of the pedals may have different centers in the two different conditions. The front end portion of the walking orbit bends up, letting the heels land on the ground first for a user to stand stably. Further, a slope adjuster is provided to adjust the angle of the stop members relative to the upper connect rods for making three modes of exercise.
