DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-3, a treadmill in accordance with the preferred embodiment of the present invention comprises a treadmill body (or running platform) 1. The treadmill body 1 includes a main support unit 11 and a belt mechanism 12. The main support unit 11 includes at least one first frame 111, at least one second frame 112 located under the at least one first frame 111, multiple first elastic shock-absorbing members 113 mounted between the at least one first frame 111 and the at least one second frame 112 to provide shock-absorbing and vibration damping functions, and multiple second elastic shock-absorbing members 114 mounted on a bottom of the at least one second frame 112 to provide shock-absorbing and vibration damping functions. The at least one first frame 111 and the at least one second frame 112 are arranged and combined to construct a multi-layer frame structure. The first elastic shock-absorbing members 113 are dispersed and arranged between the at least one first frame 111 and the at least one second frame 112. The second elastic shock-absorbing members 114 are dispersed and arranged on the bottom of the at least one second frame 112. The belt mechanism 12 is mounted on the at least one first frame 111.

In practice, the first elastic shock-absorbing members 113 are mounted between the at least one first frame 111 and the at least one second frame 112 to provide shock-absorbing and vibration damping functions. The belt mechanism 12 is mounted on the at least one first frame 111. The second elastic shock-absorbing members 114 are dispersed and arranged on the bottom of the at least one second frame 112. Thus, when the user are running on the belt mechanism 12, the first elastic shock-absorbing members 113 provides shock-absorbing and vibration damping functions between the at least one first frame 111 and the at least one second frame 112, so that the vibration produced by the belt mechanism 12 will not be directly transmitted to the ground, thereby efficiently reducing noise produced during the running process, and thereby preventing the noise from causing disturbance to the neighbor downstairs. In addition, the second elastic shock-absorbing members 114 are located between the at least one second frame 112 and the ground to further provide shock-absorbing and vibration damping functions so as to eliminate the noise produced by vibration. In such a manner, the multi-layer frame structure of the at least one first frame 111 and the at least one second frame 112 cooperates with the first elastic shock-absorbing members 113 and the second elastic shock-absorbing members 114 to efficiently eliminate the vibration noise during running, and to prevent the noise from causing disturbance to the neighbor downstairs.

In the preferred embodiment of the present invention, the main support unit 11 includes a first frame 111 and a second frame 112 which construct a two-layer frame structure.

In the preferred embodiment of the present invention, each of the first elastic shock-absorbing members 113 is a rubber cushion (or pad), and each of the second elastic shock-absorbing members 114 is a rubber sucker base. Alternatively, each of the first elastic shock-absorbing members 113 is a spring structure.

In the preferred embodiment of the present invention, the first elastic shock-absorbing members 113 and the second elastic shock-absorbing members 114 are arranged at different height. In addition, the first elastic shock-absorbing members 113 and the second elastic shock-absorbing members 114 are alternated (or staggered) with each other. In such a manner, after the first elastic shock-absorbing members 113 reduce the vibration of the at least one first frame 111, the residual vibration will not be directly transmitted through the at least one second frame 112 and the second elastic shock-absorbing members 114 to the ground. Thus, the first elastic shock-absorbing members 113 and the second elastic shock-absorbing members 114 provide better vibration damping and noise eliminating functions.

In the preferred embodiment of the present invention, the belt mechanism 12 includes an endless running belt (or treadmill belt) 121, a support board 122 supporting an upper part of the running belt 121, and a drive motor module (or motor drive system) 123 driving and moving the running belt 121. The running belt 121 is movably connected with the at least one first frame 111 by two rollers. The drive motor module 123 is installed and secured on the at least one first frame 111. The drive motor module 123 has a drive end mechanically connected with one of the two rollers by a mechanic transmission connecting structure. The main support unit 11 further includes multiple third elastic shock-absorbing members 115 mounted on the at least one first frame 111 to provide shock-absorbing and vibration damping functions. The third elastic shock-absorbing members 115 are dispersed and arranged on the at least one first frame 111. The support board 122 is elastically supported on the third elastic shock-absorbing members 115. The support board 122 faces an inner face of the upper part of the running belt 121. Thus, the third elastic shock-absorbing members 115 further provides vibration damping and noise eliminating functions during running.

In the preferred embodiment of the present invention, each of the third elastic shock-absorbing members 115 is a rubber cushion (or pad). Alternatively, each of the third elastic shock-absorbing members 115 is a spring structure.

In the preferred embodiment of the present invention, the treadmill body 1 further includes two footboards (or footrests or treadles) 13 mounted on two sides of the at least one first frame 111.

In the preferred embodiment of the present invention, the treadmill further comprises an upright rack 2 having a lower end mounted on the at least one second frame 112, and a controller (or a console assembly) 3 mounted on the upright rack 2. The upright rack 2 is provided with a handlebar. The controller 3 is used to adjust an operation mode of the belt mechanism 12. The controller 3 includes contact switches or push buttons. In such a manner, the upright rack 2 is directly mounted on the at least one second frame 112, without contacting with the at least one first frame 111, so that the upright rack 2 is not affected by the vibration produced during running. Thus, the controller 3 on the upright rack 2 will not produce vibration or sway so that the user operates the controller 3 at a steady state.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
