Static electricity remover of a treadmill
Abstract
The present invention relates to a static electricity remover of
a treadmill includes a handrail, a base frame and foot supports. A
console is disposed on the handrail while a walking frame is
provided within the base frame. A walking belt is extended around
the walking frame and a front and a rear frame so that the walking
belt can be brought into rotation by means of a motor and a
transmission belt. At least one set of conductive elements is
interposed between the walking frame and the base frame so as to
carry the static electricity accumulated in the main body of the
treadmill through the base frame and the foot supports to the
ground.

Claims
What is claimed is:
1. A static electricity remover of a treadmill comprising a
handrail, a base frame and foot supports, a console being disposed
on said handrail while a walking frame is provided within said base
frame, a walking belt being extended around said walking frame and
a front and a rear frame so that said walking belt can be brought
into rotation by means of a motor and a transmission belt; wherein
at least one set of conductive elements is interposed between said
walking frame and said base frame so as to carry the static
electricity accumulated in said main body of said treadmill to the
ground.
2. The static electricity remover of a treadmill as recited in
claim 1, wherein said conductive elements can be conductive metal
piece or conductive metal wire, or the like.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Fields of the Invention
[0002] The present invention relates to a static electricity
remover of a treadmill, and more particularly, to a device which
the static electricity accumulated in the treadmill can be
completely removed in order to maintain the normal operation of the
console.
[0003] 2. Description of the Prior Art
[0004] As shown in FIG. 1, the treadmill 10 is used for operators
to make an in-place walking or jogging exercise. The user can
operate a console 11 to control the speed of the walking belt 12 in
accordance with the personal physical state to meet the exercise
needs.
[0005] However, the static electricity will be produced and stored
in the treadmill during the rubbing rotation between the walking
belt 12 and the roller 13. When the static electricity is
accumulated to a certain extent, it will strongly interfere the
operation of the console 11 even which could lose its full
function. In addition to damaging all electronic and electric
components, a body injury of the user can even happen during the
exercise session, for example, when the motor 14 and the walking
belt 12 suddenly stop rotating.
[0006] Conventionally, the treadmill 10 utilizes conductive metal
wires (not shown) embedded in the walking belt 12 to carry the
static electricity through the front and rear rollers 13, the base
frame 15 and the foot supports 16 to the ground. This kind of
design to carry off the static electricity is useful in the initial
stage. However, the effect will be decreasing day by day, and the
console 11 is finally out of order. The reason lies in that the
conductive metal wires embedded in the walking belt 12 are
gradually broken off due to the long-term continuous tension and
rapid rotation of the walking belt 12.
[0007] Besides, the conventional treadmill 1 0 is provided with
cushioning rubber pad 18 between the walking frame 17 and the base
frame 15 in order to prevent the walking frame 17 from shaking.
However, the cushioning rubber pad 18 is made of insulating
material so that the static electricity will be accumulated in the
walking frame 17 and not smoothly carried off. In other words, the
conventional design utilizes the conductive metal wires embedded in
the walking belt 12 as the only means to carry off the static
electricity. However, it's neglected that the static electricity
accumulated within the walking frame 17 can't be effectively
removed.
SUMMARY OF THE INVENTION
[0008] It is a primary object of the present invention to eliminate
the above-mentioned drawbacks and to provide a static electricity
remover of a treadmill through which the not only the local static
electricity but also that accumulated within the walking frame can
be completely removed. Meanwhile, the conductive elements are
fitted to the walking frame to prevent them from being broken
off.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The accomplishment of this and other objects of the
invention will become apparent from the following description and
its accompanying drawings of which:
[0010] FIG. 1 is a side view of a conventional treadmill;
[0011] FIG. 2 is a side view of a preferred embodiment of the
present invention; and
[0012] FIG. 3 is a side view of a preferred embodiment of the
present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] First of all, referring to FIG. 2, the treadmill 20 of the
present invention includes a handrail 21, a base frame 22 and foot
supports 23. A console 24 is disposed on the handrail 21 while a
walking frame 25 is provided within the base frame 22. A walking
belt 27 is extended around the walking frame 25 and a front and a
rear frame 26 so that the walking belt 27 can be brought into
rotation by means of a motor 38 and a transmission belt 29. At
least one set of conductive elements 30 is interposed between the
walking frame 25 and the base frame 22 so as to carry the static
electricity accumulated in the main body 10 of the treadmill 20 to
the ground.
[0014] Referring to FIGS. 2 and 3, the conductive elements 30 can
be conductive metal piece 301 or conductive metal wire 302, or the
like.
[0015] Certainly, it's difficult to imagine that the carrying-off
effect of the design of the present invention can reach the
expected effect since many think that the walking frame 25 is made
of wood which is also insulting material with high resistance
value. It's necessary to emphasize that the existence of the static
electricity and the accumulating way thereof are exactly different
from the well-known current. For example, it's easy for textile,
especially sweater or plastic fiber clothes, to accumulate the
static electricity so that a "beep-bia" sound is created due to the
interaction of the electrostatic current when we get undressed.
However, the textile is also the insulting material. Accordingly,
it's no wonder that the walking frame 25 made of wood can
accumulate the static electricity.
[0016] In brief, most of the static electricity produced by any
component of the treadmill 20 will be accumulated in the walking
frame 25 because of the contact therebetween. The present invention
can just eliminate drawbacks of the conventional treadmill and
reaches the expected effect.
[0017] Many changes and modifications in the above-described
embodiment 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.
