Abstract

A rear drive type electric treadmill wherein a driving motor is disposed at the rear end of a platform for directly driving a rear drum that is matched with a front drum so as to bring a continuous moving belt in a continuous movement. In this way, the force to rotate the continuous moving belt comes from a position behind an operator, thereby eliminating the frustration of the continuous moving belt each time when a force acts thereon. Moreover, a horizontal portion of the base frame has a slide recess facing to the platform. The platform is provided with a projecting wheel set at both sides thereof in match of the slide recesses. In this way, the platform is easily lifted upward in a vertical position. Consequently, it is beneficial for the operator to fold-up and move the treadmill.

Claims

1. A rear drive type electric treadmill having a base frame, a driving motor, a handrail bracket, a handrail unit, a platform, a lifting motor, a lifting drive rod, and a front support,

wherein the driving motor is disposed at the rear end of the platform for directly driving a rear drum that is matched with a front drum so as to bring a continuous moving belt in a continuous movement,

wherein the base frame includes a horizontal portion and a secondary wheel support, and wherein the horizontal portion has a slide recess forming a track with an opening facing the platform, and wherein the platform is provided with a projecting wheel set at both sides thereof so that, in folding the platform upward, the platform rotates on a shaft between the handrail bracket and the base frame in such a way that the platform is lifted by sliding the projecting wheel sets in the slide recesses until a vertical fold-up state is reached.

2. The rear drive type electric treadmill as recited in claim 1, wherein the lifting motor and the lifting drive rod are installed at the bottom of the platform in such a manner that the front support pivotally disposed near the front end of the platform is swiveled about a pivot.

3. The rear drive type electric treadmill as recited in claim 1, wherein the slide recess extends along the horizontal portion.

4. A rear drive type electric treadmill having a base frame, a driving motor, a handrail bracket, a handrail unit, a platform, and a front support,

wherein the base frame includes a horizontal portion and a secondary wheel support, and wherein the horizontal portion has a slide recess forming a track with an opening facing the platform, and wherein the platform is provided with a projecting wheel set at both sides thereof so that, in folding the platform upward, the platform rotates on a shaft between the handrail bracket and the base frame in such a way that the platform is lifted by sliding the projecting wheel sets in the slide recesses until a vertical fold-up state is reached.

5. The rear drive type electric treadmill as recited in claim 4, wherein the slide recess extends along the horizontal portion.
