Abstract

The present invention relates to a folding mechanism of an exercise treadmill having a treadmill frame and a support frame. A connecting rod is mounted on the support frame and extends to the front lower side of the exercise treadmill such that the other end of the connecting rod is pivotally connected the front portion of the treadmill frame. In addition, a ground touching roller is mounted to either side of the front end of the bottom of the treadmill frame. When the rear end of the treadmill frame is lifted to perform a folding action, the ground touching rollers are operative to facilitate the lifting action of an operator such that the operation is easy and has a labor-saving effect.

Claims

1. A folding mechanism of an exercise treadmill comprising:

a) a treadmill frame having a treadmill walking belt, a drive mechanism, which drives said treadmill walking belt, a swivel foot roller pivotally mounted to each side of a rear end of said treadmill frame, and a ground touching roller rotatably mounted to each side of a front end of a bottom of said treadmill frame; and

,

b) a support frame having an electronic console thereon; and

,

c) a curved connecting rod pivotally mounted at a first connecting rod end to said support frame and at a second connecting rod end to said treadmill frame, wherein the treadmill frame is rotatable relative to the support frame, whereby the support frame remains stationary and the ground touching rollers are operative to facilitate the lifting action of the user when the treadmill frame rotates between an open position for use and a closed position for storage.

2. A folding mechanism of an exercise treadmill according to claim 1, further comprising an auxiliary roller rotatably connected to each inner side of a bottom of said support frame.
