SHAKING MECHANISM OF A TREADMILL
A shaking mechanism of a treadmill having a shaking plate attached to the bottom of a platform of the treadmill. The shaking plate is driven by at least one shaking drive unit disposed on a supporting plate of a base frame such that the platform creates an expected up-and-down shaking effect.
1. Fields of the Invention
The invention relates to a shaking mechanism of a treadmill, and more particularly, to a mechanism that ensures a reduction of the frictional loss between a continuous moving belt and a platform. Meanwhile, the connection of motor nerves of the operator can be effectively enhanced.
2. Description of the Related Art
At present, many athletic physiologists found that the connection of the motor nerves of the muscles can be effectively enhanced when the operator walks on the treadmill with a regular and proper vibration, particularly during the cooldown stage after an exercise. In this way, the hardening effect of the motor muscles can be effectively enhanced. The invention is designed according to the experiment results. Up to now, the conventional treadmills in the market don't have the proper up-and-down shaking effect during the walking exercise.
SUMMARY OF THE INVENTIONAn object of the invention is to provide a shaking mechanism of a treadmill that includes a shaking plate and a shaking drive unit attached to the bottom of a platform of the treadmill such that the platform may create an expected and proper up-and-down shaking effect. Meanwhile, the expected exercise effect is achieved.
According to the invention, a shaking mechanism of a treadmill includes a shaking plate attached to the bottom of a platform of the treadmill. The shaking plate is driven by at least one shaking drive unit disposed on a supporting plate of a base frame such that the platform creates an expected up-and-down shaking effect
The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
The present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
Referring to
Generally, each electric treadmill 10 includes a plurality of cushioning elements 21 between the platform 17 and both sides of the electric treadmill 10 for achieving the proper exercise cushioning effect. Likely, the treadmill in accordance with the invention also employs the function of the cushioning elements 21 for effectively control the shaking intensity and the restoring effect of the platform 17.
As shown in
The electromagnetism and the cam mechanism belong to the conventional electric transmission principle so that no further descriptions thereto are given hereinafter.
In addition, we find after an empirical test that the friction resistance between the continuous moving belt 16 and the platform 17 can be reduced when they are brought into a shaking state. Furthermore, the service life of the continuous moving belt 16 can be prolonged, thereby increasing the added application value.
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.
Claims
1. A shaking mechanism of a treadmill having a transmission motor at one side of a base frame thereof in cooperation with a transmission belt, a front roller and a rear roller for rotating a continuous moving belt around a platform,
- wherein a shaking plate is attached via a connecting piece to the bottom of the platform of the electric treadmill, and the shaking plate is driven by at least one shaking drive unit disposed on a supporting plate of the base frame such that the platform creates an expected up-and-down shaking effect.
2. The shaking mechanism of a treadmill as claimed in claim 1, wherein the shaking drive unit includes more than one set of permanent magnets (that is fixed at the bottom of the shaking plate) and electromagnets (that are disposed at the end of the supporting plate) corresponding to the permanent magnets in quantity as well as in position.
3. The shaking mechanism of a treadmill as claimed in claim 1, wherein the shaking drive unit can be replaced by an electric motor in cooperation with more than one cam mechanism.
