Static eliminator for a motorized treadmill
Abstract
A static eliminator adapted to an instrument panel of a
motorized treadmill to eliminate static for the runner on the
treadmill without having to wear any anti-static gear includes an
ion generator and a fan. The ion generator is disposed behind the
fan to alternatively generate cations and anions. The fan blows the
ion current bearing-cations and anions to the runner for
eliminating static by ion neutralization.

Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to a static eliminator for a
motorized treadmill, and more particularly, to one that delivers an
ion current carrying cations and anions with a fan to neutralize
static building up on the runner.
[0003] (b) Description of the Prior Art
[0004] Whereas a runner is working out on a motorized treadmill,
the static charges will usually build up on the body of the runner
due to the friction between the deck and the clothes. Once the
runner touches the hand-rest, the runner may get electric shock
since the hand-rest contacts the ground. The deck is an insulator
that prevents the discharge of static built on the runner if he/she
does not contact the treadmill. Accordingly, the accumulated static
causes the voltage to rise, thus to fail or damage the electronic
equipment attached to the treadmill. Static most frequently causes
chaos to the electronic control system resulting in sudden fast
moving or stop of the deck to expose the runner to the accident of
falling on the ground.
[0005] Generally, the voltage of static discharge that can be
sensed by the human body ranges between 3,000V.about.5000V.
However, it takes only few hundred volts to cause permanent damage
of an electronic device. Therefore, a static elimination device is
usually adapted to the structure of the treadmill to eliminate the
static generated in the course of running by the user of the
treadmill.
[0006] One improvement involves the placement of an anti-static
mesh in the deck. The anti-static mesh is essentially intervened
with fibers and wires to lead the static generated on the deck to
the ground through the contact of the deck roller and the frame of
the treadmill.
[0007] The deck is made of rubber and is vulnerable to show
resilience fatigue after using for a long time. It requires
periodical readjustment of the tension of the deck. Since the
tenacity of the anti-static mesh differs from that of the deck, the
anti-static mesh can be easily broken up to lose its function in
the course of readjusting the tension of the deck. When the
anti-static mesh is broken up, an immediately replacement of the
deck is required. It is not likely to expect the user to replace
the deck by himself/herself.
[0008] Another improvement is having the runner to wear anti-static
ring to lead the static away from the runner. However, wearing the
anti-static ring may become a burden to the runner while running on
the deck.
SUMMARY OF THE INVENTION
[0009] The primary purpose of the present invention is to provide a
static eliminator adapted to an instrument panel of a motorized
treadmill to make the runner feeling easier and more comfortable
without having to wear any anti-static gear.
[0010] To achieve the purpose, the static eliminator contains an
ion generator to alternatively deliver cations and anions and a fan
to blow the ion current carrying the cations and anions to the
runner to neutralize the static building up on the runner.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a schematic view showing a working status of a
preferred embodiment of the present invention.
[0012] FIG. 2 is an exploded view of the preferred embodiment of
the present invention.
[0013] FIG. 3 is a schematic view showing another working status of
the preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Referring to FIGS. 1 and 2, the present invention relates to
a static eliminator adapted to a motorized treadmill. A notch (111)
is provided on an instrument panel (11) in front of the motorized
treadmill (1) to receive the insertion of a static eliminator (2).
A lid (112) is provided in relation to the notch (111) on the
instrument panel (11) and screwed to the instrument panel (11) with
a plurality of fasteners (113). The static eliminator (2) includes
an ion generator (21) and a fan (22). The ion generator (21) is
deposed behind the fan (22) to alternatively generate cations and
anions. That is, the ion generator (21) generates only cations for
a certain period of time and then generates only anions in cycles.
The fan blows an ion current carrying cations and anions to the
runner. The runner while enjoying the breeze of the ion current has
the static built on his/her body to be neutralized.
[0015] For example, if the runner is one meter away from the static
eliminator (2), the static eliminator (2) alternatively delivers
more than five million cations and anions to completely eliminate
the static at a voltage of 5000V within six seconds. To test the
static elimination results, a static generator is disposed at the
front of the instrument panel (11) adapted with the static
eliminator (2). The static generator is caused to generate a static
at the voltage around 5700V, later measured at approximately 5800V
using a static meter. The static eliminator (2) is then started to
deliver the ion current carrying cations and anions. As measured,
the static voltage is dropped to 400V to prove that the present
invention is capable of effectively neutralizing and eliminating
the static created on the motorized treadmill.
[0016] Furthermore, the static elimination result is achieved only
by having the ion current delivered by the static eliminator (2) to
be directed at the runner. As illustrated in FIG. 3 for another
preferred embodiment of the prevent invention, the static
eliminator (2) is made a standing alone unit by having the ion
generator (21) and the fan (22) placed inside a casing (23) of the
static eliminator (2). The static eliminator (2) is fixed onto the
instrument panel (11) by means of a fixture (3) to achieve the same
static elimination result.
