Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a treadmill and, more
particularly, to a walking board assembly for a treadmill.
2. Description of the Related Art
[0002] A conventional treadmill comprises a walking board, a
walking belt, and a plurality of rollers. The walking belt rotates
on the walking board along a closed trajectory, to facilitate the
user stepping on the walking board successively. The walking belt,
the rollers and the walking board rub one another for a long period
of time, such that a determined amount of static electricity is
accumulated and easily discharged to the user, thereby scaring the
user and causing an uncomfortable sensation to the user, and easily
interfering with the electronic components of the treadmill. An
antistatic yarn is added to the inner side of the walking belt to
eliminate the static electricity. However, the antistatic yarn is
easily worn out when the walking belt and the walking board rub
constantly during a long-term utilization, and loses its antistatic
effect gradually. The walking belt, the rollers, and the walking
board rub frequently, such that the walking belt and the walking
board are easily worn out during a long-term utilization, thereby
decreasing the lifetime of the walking belt and the walking board.
A slip assistant strip is adhered to the inner side of the walking
belt to reduce the friction between the walking belt and the
walking board. Alternatively, a melamine layer is stuck on the top
surface of the walking board to reduce the friction between the
walking belt and the walking board. However, the friction produces
a high temperature. Thus, a wear-resistant and high-temperature
resistant surface layer is stuck to the walking board, and a
lubricant or wax is sprayed on the surface layer, to reduce the
friction between the walking belt and the walking board, such that
the walking belt is moving on the walking board smoothly, thereby
preventing from producing resistance and high temperature due to
frequent friction during a long-term utilization. However, the user
has to replenish the lubricant or wax frequently when the
conventional treadmill is operated during a period of time, thereby
greatly causing inconvenience to the user, and thereby increasing
the cost.

layer 30 is provided with a plurality of heat dissipation holes 31.
The heat dissipation holes 31 perforate the top face 301 and the
bottom face 302 of the heatsink elastic layer 30. The heatsink
elastic layer 30 is provided with a plurality of recessed flow
channels (or ducts) 32. The flow channels 32 are formed in the
bottom face 302 of the heatsink elastic layer 30 and define a
plurality of circulation spaces 33 between the heatsink elastic
layer 30 and the base board 10. The flow channels 32 extend through
a side edge of the heatsink elastic layer 30. The flow channels 32
are connected to a lower end of each of the heat dissipation holes
31. The flow channels 32 are directed in a horizontal
direction.
[0021] In the preferred embodiment of the present invention, the
heatsink elastic layer 30 is made of foam material.
[0022] In the preferred embodiment of the present invention, the
heat dissipation holes 31 are arranged in a vertical direction.
[0023] In the preferred embodiment of the present invention, the
flow channels 32 extend through the heatsink elastic layer 30
transversely. The flow channels 32 are arranged regularly. The flow
channels 32 are adjacent to each other.
[0024] In the preferred embodiment of the present invention, the
flow channels 32 are arranged linearly.
[0025] In the preferred embodiment of the present invention, each
of the flow channels 32 has a cross section defining an arcuate
concave face.
[0026] In practice, the treadmill walking board assembly is mounted
on a treadmill and surrounded by a walking belt which forms a
closed revolving track.
[0027] Referring to FIGS. 5-8, the flow channels 32 are formed in
the top face 301 of the heatsink elastic layer 30 and define a
plurality of circulation spaces 35 between the heatsink elastic
layer 30 and the wear-resistant thin layer 20. The flow channels 32
are connected to an upper end of each of the heat dissipation holes
31.
[0028] Referring to FIG. 9, the wear-resistant thin layer 20 is
provided with a plurality of heatsink holes 21. The heatsink holes
21 perforate the wear-resistant thin layer 20.
[0029] Referring to FIG. 10, the flow channels 32 extend through
the heatsink elastic layer 30 longitudinally. The flow channels 32
are arranged regularly. The flow channels 32 are adjacent to each

[0031] The structure, design, construction, and function of the
treadmill walking board assembly of the present invention are
illustrated as follows.
[0032] As shown in FIGS. 1-4, in the first preferred embodiment of
the present invention, the flow channels 32 are formed in the
bottom face 302 of the heatsink elastic layer 30 and are connected
to the lower end of each of the heat dissipation holes 31. The flow
channels 32 are directed in a horizontal direction. In such a
manner, when the user is stepping or running on the treadmill
walking board assembly, the heatsink elastic layer 30 is
compressed, such that the hot air is delivered through the heat
dissipation holes 31 and the flow channels 32, and are drained
outward from the side edge of the heatsink elastic layer 30.
[0033] As shown in FIGS. 5-8, in the second preferred embodiment of
the present invention, the flow channels 32 are formed in the top
face 301 and the bottom face 302 of the heatsink elastic layer 30
and are connected to the upper end and the lower end of each of the
heat dissipation holes 31 respectively. In such a manner, when the
user is stepping or running on the treadmill walking board
assembly, the heatsink elastic layer 30 is compressed, such that
the hot air is delivered through the upper end and the lower end of
each of the heat dissipation holes 31 and the flow channels 32 of
the top face 301 and the bottom face 302, and are drained outward
from the side edge of the heatsink elastic layer 30.
[0034] As shown in FIG. 9, in the third preferred embodiment of the
present invention, the wear-resistant thin layer 20 is provided
with a plurality of heatsink holes 21 that perforate the
wear-resistant thin layer 20. In such a manner, when the user is
stepping or running on the treadmill walking board assembly, the
heatsink elastic layer 30 is compressed, such that the hot air is
delivered through the lower end of each of the heat dissipation
holes 31 and the flow channels 32 of the bottom face 302, and are
drained outward from the side edge of the heatsink elastic layer
30. At the same time, the hot air is also delivered through the
upper end of each of the heat dissipation holes 31, the flow
channels 32 of the top face 301, and the side edge of the heatsink
elastic layer 30, and are drained outward from the heatsink holes
21 of the wear-resistant thin layer 20.
[0035] Accordingly, the treadmill walking board assembly of the
present invention has the following advantages.
[0036] 1. When the user is stepping or running on the treadmill
walking board assembly and presses the heatsink elastic layer 30,
the hot air is delivered through the heat dissipation holes 31, the
flow channels 32, and the side edge of the heatsink elastic layer
30, and are drained outward from the heatsink holes 21 of the
wear-resistant thin layer 20, thereby achieving the purposes of
flow guidance, air exhaust and heat radiation.
[0037] 2. When the user is stepping or running on the treadmill
walking board assembly, the heatsink elastic layer 30 is compressed
and released repeatedly, such that the hot air is drained through
and sucked into the heat dissipation holes 31 and the flow channels
32 successively in a circulating manner, to produce an air
ventilating effect like an air cushion, thereby enhancing the
shock-absorbing effect of the treadmill walking board assembly.
[0038] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
