Definitions

  • the invention relates to a cushioning mechanism for a treadmill, and more particularly, to a cushioning mechanism having a compact configuration while achieving an optimal shock-absorbing effect.
  • a cushioning mechanism of a treadmill is adapted to support a platform frame.
  • a vibration action is created when the platform frame is exposed to a continuous treading force by an operator thereon.
  • a reaction force will, in turn, act on the feet of the operator, thereby giving him a little discomfort now and again. This discomfort can be relieved by the cushioning mechanism.
  • Another object of the invention is to provide the means such that the user can adjust the cushioning force of the cushioning element by himself. In this way, the user can perform an operator-oriented adjustment according to personal operation habits for ensuring a comfortable operation. Accordingly, a resistance-adjusting element is provided at the bottom of the guidewheel. A free personal adjustment of the cushioning force may be achieved by the inclination of the resistance-adjusting element.
  • a treadmill in accordance with the invention includes a handle frame assembly 10 and a platform frame 20.
  • the handle frame assembly 10 is positioned at both sides of a front end of the platform frame 20.
  • An electronic console 11 is installed at a top side of the handle frame assembly 10 while two base bars 12 are attached to a bottom end of the handle frame assembly 10.
  • the platform frame 20 is pivotally mounted near a bottom portion of the handle frame assembly 10.
  • a continuous moving belt 25 works in cooperation with a motor 21, a belt 22, a front roller 23, and a rear roller 24 to ensure a circulating operation.
  • a pair of ⁇ -shaped rigid connection elements 30 and a pair of pivotal rigid cushioning elements 40 are interposed between the bottom surface of both sides of the platform frame 20 and the base bars 12.
  • the pivotal rigid cushioning element 40 includes a guidewheel 41 at one end thereof. In this way, the guidewheel 41 is movable on the surface of the base bar 12 when the platform frame 20 is moved up and down by the external forces applied to it (see FIG. 3 & Fig. 5 ). Accordingly, the cushioning and restoring effects can be achieved.
  • a resistance-adjusting element 42 is provided at the bottom of the guidewheel 41. A free adjustment of the cushioning force may be achieved by the inclination of the resistance-adjusting element 42.
  • An auxiliary supporting element 50 is pivotally interposed between both sides of the platform frame 20 and the handle frame assembly 10, respectively. As a result, a complete cushioning and restoring effect can be ensured.
  • the sliding resistance created by the resistance adjusting element 42 and acting on the guidewheel 41 is smaller when the inclination of the resistance adjusting element 42 approaches to the horizontal position, as shown in FIGS. 2 and 3 . To the contrary, the sliding resistance acting on the guidewheel 41 will be increased, as shown in FIGS. 4 and 5 .
  • the ⁇ -shaped rigid connection elements 30 can also achieve the cushioning effect.
  • the ⁇ -shaped rigid connection elements 30 regain their original shape after being compressed or deformed by the external forces applied thereto. Accordingly, an optimal cushioning action may be achieved by the cooperation of the ⁇ -shaped rigid connection elements 30, the pivotal rigid cushioning elements 40 and the auxiliary supporting elements 50.
  • a soft stop element 60 can be attached to the surface of the base bars 12, respectively. In case of overload on the platform frame 20 or damage of relevant elements, the soft stop element 60 can act against the downward movement of the platform frame 20. In this way, the operator's safety can be assured.
  • the pivotal rigid cushioning element 40 may be made of a plurality of arched steel plates for increasing the whole strength.
  • the pivotal rigid cushioning elements 40 may be symmetrically designed in ⁇ -form for enhancing the whole effect thereof.
