    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the drawings and initially to FIG. 1, a treadmill with a shock-absorbing and cushioning structure in accordance with a preferred embodiment of the present invention comprises a [0037] base frame 10, and a belt frame 20.
  • The [0038] base frame 10 is provided with a support rack 11 which is provided with two handles 12. The belt frame 20 is provided with two parallel rollers 21 a and 21 b, a board 200 located between the two rollers 21 a and 21 b, and a belt 22 mounted around the two rollers 21 a and 21 b to encompass the board 200 which is used to support the belt 22. The base frame 10 has a front end provided with a connecting portion 14, and a rear end provided with a pivot portion 13. Preferably, the connecting portion 14 extends under the bottom of the base frame 10.
  • The [0039] belt frame 20 has a front end provided with a connecting portion 24 mating with the connecting portion 14 of the base frame 10, and a rear end provided with a pivot portion 23 mating with the pivot portion 13 of the base frame 10. The pivot portion 23 of the belt frame 20 is pivotally mounted on the pivot portion 13 of the base frame 10.
  • The treadmill in accordance with the present invention further comprises a [0040] cushioning device 30 mounted between the connecting portion 14 of the base frame 10 and the connecting portion 24 of the belt frame 20. The cushioning device 30 has a bottom portion pivotally mounted on the connecting portion 14 of the base frame 10 and a top portion pivotally mounted on the connecting portion 24 of the belt frame 20. Thus, the base frame 10 is disposed at a stationary state, and the belt frame 20 is pivotable relative to the base frame 10, so that the cushioning device 30 may produce a better and more stable cushioning effect between the base frame 10 and the belt frame 20.
  • The [0041] cushioning device 30 includes a lower pivot ear 33 secured on the connecting portion 14 of the base frame 10, a piston cylinder 34 pivotally mounted on the lower pivot ear 33, an upper pivot ear 31 secured on the connecting portion 24 of the belt frame 20, a piston rod 32 pivotally mounted on the upper pivot ear 31 and slidably mounted in the piston cylinder 34, and an elastic member 35 mounted between the piston rod 32 and the piston cylinder 34 and having a first end rested on the piston rod 32 and a second end rested on the piston cylinder 34. Thus, when the piston rod 32 is moved relative to the piston cylinder 34, the elastic member 35 may be compressed to produce a better and more stable cushioning effect between the piston rod 32 and the piston cylinder 34. Preferably, the elastic member 35 is a compression spring.
  • Referring to FIGS. [0042] 1-3, in assembly, the pivot portion 23 of the belt frame 20 is pivotally mounted on the pivot portion 13 of the base frame 10 by a shaft (not shown). Then, the upper pivot ear 31 of the cushioning device 30 is secured on the connecting portion 24 of the belt frame 20, and the lower pivot ear 33 of the cushioning device 30 is secured on the connecting portion 14 of the base frame 10, and the connecting portion 14 extends under the bottom of the base frame 10 and to touch the ground so that the cushioning device 30 becomes a more stable structure. Then, the piston rod 32 is pivotally mounted on the upper pivot ear 31 and the piston cylinder 34 is pivotally mounted on the lower pivot ear 33. Then, the elastic member 35 is mounted on the piston rod 32, and the piston rod 32 is slidably mounted in the piston cylinder 34, with the first end of the elastic member 35 being rested on the piston rod 32 and with the second end of the elastic member 35 being rested on the piston cylinder 34. Thus, the treadmill with a shock-absorbing and cushioning structure in accordance with the preferred embodiment of the present invention is assembled.
  • In operation, referring to FIGS. 3 and 4 with reference to FIGS. 1 and 2, when the user is running on the [0043] belt 22 and the board 200, the force is applied on the belt frame 20. At this time, the rear end of the belt frame 20 is pivotally mounted on the rear end of the base frame 10, and the base frame 10 is supported on the ground rigidly and stably, so that the belt frame 20 is pivoted relative to the base frame 10. In addition, cushioning device 30 is mounted between the connecting portion 14 of the base frame 10 and the connecting portion 24 of the belt frame 20, so that the cushioning device 30 may produce a better and more stable cushioning effect between the base frame 10 and the belt frame 20, thereby preventing from incurring vibration and oscillation during running of the user.
  • Referring to FIGS. 5 and 6, the treadmill with a shock-absorbing and cushioning structure in accordance with the preferred embodiment of the present invention is available for a motorized treadmill. A driven [0044] wheel 40 is secured on the shaft of the roller 21 a of the belt frame 20. The base frame 10 is provided with a motor 41 and a drive wheel 42. A driving belt 43 is mounted between the driven wheel 40 and the drive wheel 42. When the belt frame 20 is oscillated, the distance between the driven wheel 40 and the drive wheel 42 is slightly changed. At this situation, an idler device 44 is mounted on the driving belt 43, so that the driving belt 43 may be driven efficiently.
  • Accordingly, the treadmill with a shock-absorbing and cushioning structure in accordance with the preferred embodiment of the present invention has the following advantages. [0045]
  • 1. The [0046] base frame 10 is separated from the belt frame 20, wherein one end of the belt frame 20 is pivotally mounted on one end of the base frame 10, and the other end of the belt frame 20 is supported on the other end of the base frame 10 by a cushioning device 30. Thus, the base frame 10 is disposed at a stationary state, and movement of the belt frame 20 is efficiently cushioned by the cushioning device 30, thereby enhancing the stability of the treadmill.
  • 2. The [0047] base frame 10 is disposed at a stationary state, and movement of the belt frame 20 is efficiently cushioned by the cushioning device 30, thereby reducing the force applied on the cushioning device 30, and thereby increasing the lifetime of the cushioning device 30.
  • 3. The [0048] base frame 10 is disposed at a stationary state, thereby enhancing the stability and stiffness of the treadmill.
  • 4. The [0049] base frame 10 is disposed at a stationary state, and movement of the belt frame 20 is efficiently cushioned by the cushioning device 30, thereby reducing the noise in use.
  • 5. The [0050] belt frame 20 has a light weight and may be detached easily, thereby facilitating maintenance of the treadmill.
  • Although the invention has been explained in relation to its preferred embodiment 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 true scope of the invention. [0051]
