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.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Fields of the Invention
[0002] 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.
[0003] 2. Description of the Related Art
[0004] 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 INVENTION
[0005] An 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.
[0006] 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
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The accomplishment of this and other objects of the
invention will become apparent from the following description and
its accompanying drawings of which:
[0008] FIG. 1 is a perspective view of a treadmill;
[0009] FIG. 2 is a cutaway view of a first embodiment of the
invention;
[0010] FIG. 3 is a partial top view of the embodiment according to
FIG. 2; and
[0011] FIG. 4 is a cutaway view of a second embodiment of the
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] The present invention will now be described in more detail
hereinafter with reference to the accompanying drawings that show
various embodiments of the invention.
[0013] Referring to FIG. 1, which a basic configuration of an
electric treadmill 10 is illustrated, the electric treadmill 10
includes a base frame 11. A transmission motor 12 is disposed at
one side of the base frame 11 of the electric treadmill 10 in
cooperation with a transmission belt 13, a front roller 14 and a
rear roller 15 for rotating a continuous moving belt 16 around a
platform 17. As shown in FIGS. 2 and 3, a shaking plate 20 is
attached via a connecting piece 18 to the bottom of the platform 17
of the electric treadmill 10. The shaking plate 20 is driven by at
least one shaking drive unit 30 disposed on a supporting plate 19
of the base frame 11 such that the platform 17 creates an expected
up-and-down shaking effect. The shaking drive unit 30 includes more
than one set of permanent magnets 31 (that is fixed at the bottom
of the shaking plate 20) and electromagnets 32 (that are disposed
at the end of the supporting plate 19) corresponding to the
permanent magnets 31 in quantity as well as in position. In this
way, an attraction or a repulsion (in the field of the
electromagnetism) takes place between the electromagnets 32 and the
permanent magnets 31 when the electric current is applied.
Therefore, the platform 17 can create an expected up-and-down
shaking effect.
[0014] 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.
[0015] As shown in FIG. 4 that illustrated another embodiment of
the invention, the shaking drive unit 30 can be replaced by another
electric motor 33 in cooperation with a cam mechanism 34. In this
way, the shaking plate 20 together with the platform 17 creates the
expected up-and-down shaking effect.
[0016] The electromagnetism and the cam mechanism belong to the
conventional electric transmission principle so that no further
descriptions thereto are given hereinafter.
[0017] 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.
[0018] 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.
