Abstract

A shock/impact absorbing structure of a treadmill wherein a second roller set is positioned correspondingly at the internal side of the first roller set and includes a front and a rear roller disposed at the front and rear ends of the supporting board. A shock/impact absorber is positioned around the second roller set. The top side of the shock/impact absorber is directed to the internal side of the running belt. When the operator steps on the running belt, the shock/impact absorber is forced to be moved in rotation by the running belt such that the shock/impact absorber has a certain region in constant contact with the supporting board, thereby providing a direct shock/impact absorbing interface for the running belt. In this way, the noise can be reduced and the injuries during the exercise sessions can be avoided.

Claims

1. A shock/impact absorbing structure of a treadmill, comprising:

a) a machine body;

b) a base frame positioned on the main body and having longitudinal bars at both sides thereof;

c) a supporting board interposed between both of the longitudinal bars, a first roller set being positioned correspondingly at the front and rear ends of the longitudinal bars; and

d) a running belt positioned around the first roller set,

wherein a second roller set is positioned correspondingly at the internal side of the first roller set and includes a front and a rear roller disposed at the front and rear ends of the supporting board; and

wherein a shock/impact absorber is in the shape of a conveyor belt and is positioned around the second roller set, and wherein the top side of the shock/impact absorber is directed to the internal side of the running belt,

whereby, when the operator steps on the running belt, the shock/impact absorber is forced to be moved in rotation by the running belt such that the shock/impact absorber has a certain region in constant contact with the supporting board, thereby providing a direct shock/impact absorbing interface for the running belt.

2. The shock/impact absorbing structure of a treadmill as recited in claim 1 wherein the shock/impact absorber is made of material selected from rubber, EVA foaming material, PU foaming material or combinations thereof.

3. The shock/impact absorbing structure of a treadmill as recited in claim 2 wherein a wear-resistant layer is positioned at the internal side of the shock/impact absorber.
