DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to the drawings and initially to FIGS. 1-4, a treadmill walking board assembly in accordance with the preferred embodiment of the present invention comprises a base (or support) board 10, a wear-resistant thin layer 20, and a heatsink elastic layer 30.

[0020] The base board 10 is made of wood material. The wear-resistant thin layer 20 is located above the base board 10. The heatsink elastic layer 30 is arranged between the base board 10 and the wear-resistant thin layer 20. The heatsink elastic layer 30 has a top face 301 abutting the wear-resistant thin layer 20 and a bottom face 302 abutting the base board 10. The heatsink elastic 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 other.

[0030] Referring to FIG. 11, the flow channels 32 are arranged irregularly.

[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 cover such modifications and variations that fall within the scope of the invention.
