Speed control rocker arm for an electric treadmill

Abstract

The present invention relates to a speed control rocker arm for an electric treadmill, The electric treadmill stated by the present invention includes an upright frame, a base frame, a front supporting leg and a rear supporting leg. A console is mounted on the upright frame, and a handrail is fitted to either side thereof. A motor-driven assembly is fitted to the base frame so that a continuous belt circles therearound for an in-place rotation. In addition, two rocker arms can be held by both hands of a user for a forward and backward swinging movement. The console fitted to a handgrip of the rocker arms contains a plurality of control keys like speed control or slope adjusting keys so that the operator can adjust the speed and slope of the treadmill while walking.
