Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Fields of the Invention [0002] The invention relates to a cushioning mechanism for a treadmill, and more particularly, to a cushioning mechanism having a compact configuration while achieving an optimal shock-absorbing effect. [0003] 2. Description of the Related Art [0004] A cushioning mechanism of a treadmill is adapted to support a platform frame. A vibration action is created when the platform frame is exposed to a continuous treading force by an operator thereon. A reaction force will, in turn, act on the feet of the operator, thereby giving him a little discomfort now and again. This discomfort can be relieved by the cushioning mechanism. [0005] Accordingly, a few rows of resilient pads are provided between the platform frame and the base frame of the treadmill to achieve an expected shock-absorbing effect. Such a conventional configuration can be easily obtained from e.g. U.S. Pat. Nos. 6,077,200, 5,746,682, etc. [0006] However, the aforementioned construction is prone to trouble with respect to its assembly, maintenance, and replacement. In particular, the disassembly and assembly of the continuous moving belt and the platform often frustrate do-it-yourselfers during the maintenance of the treadmill. Finally, they often have no choice but to turn to professional mechanic for help. SUMMARY OF THE INVENTION [0007] Thus, based on the above described drawbacks of the prior art, the designer would like to employ a mechanism exposed to the outside of the main body of the treadmill for an easy assembly while achieving the same effects. In this way, maintenance and replacement operations can be considerably simplified. So, the primary object of the invention is to provide a cushioning mechanism for an electric treadmill having a link at each side in close vicinity to the rear end of a platform frame. The links are pivotally attached to the platform frame and the base. A resilient pad facing to the bottom of the link is disposed on the base. When the platform frame is subjected to a certain force to expose the link to a synchronous vibration, the resilient pad provides an optimal shock-absorbing effect. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which: [0009] FIG. 1 is a schematic drawing of a first embodiment of the invention; and [0010] FIG. 2 is a schematic drawing of a second embodiment of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0011] Referring to FIGS. 1 and 2, a treadmill in accordance with the invention includes two handle frames 10 and a platform frame 20. [0012] The handle frame 10 is positioned at both sides of the front end of the platform frame 20. An electronic console 11 is installed at a top side of the handle frame 10 while a base 12 is coupled to a bottom end thereof. [0013] The platform frame 20 supports a platform 21 and is rotatably mounted at a bottom portion of the handle frame 10 by use of a pivot pin 22. A continuous moving belt 27 operates in cooperation with a motor 23, a belt 24, a front roller 25, and a rear roller 26 to allow it to move on a certain circulation. Each side of the rear end of the platform frame 20 is provided with a link 28 that is pivotally attached to the platform frame 20 and the base 12. [0014] A resilient pad 30 facing to the bottom of the link 28 is disposed on the base 12. When the platform frame 20 is subjected to a certain force to expose the link 28 to a synchronous vibration, the resilient pad 30 provides an optimal shock-absorbing effect. [0015] Another embodiment of the invention is shown in FIG. 2. A ground-contacting portion 13 is extended from a bottom end of the handle frame 10 while a supporting foot 14 is attached to the bottom end of the base 12. In this way, the supporting foot 14 allows for an adjustment of its supporting angle, thereby bringing the platform frame 20 in an inclined position. [0016] Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
