Definitions

  • the invention relates to a displacement detector of a shock absorption unit for a treadmill, and more particularly, to a device utilizing optical detection technique to accurately measure the displacement amount of the shock absorption unit when a force is applied onto a platform of the treadmill. Accordingly, a corresponding cushioning force of the shock absorption unit can be precisely controlled.
  • the treadmill is provided with cushioning apparatuses at suitable places for achieving a proper cushioning effect and enhancing the comfort of the operator during a workout session.
  • a protection mechanism has been developed for preventing both feet of the operator from being injured due to the too large reactive force of the platform of the treadmill. It will be particularly beneficial to the operator if hydraulic or pneumatic cylinders are used to provide more excellent cushioning effect.
  • a few prior arts such as US 4,591,147, US 5,184,988, US 4,974,831, US 4,984,810, US 5,072,928, US 5,372,559, etc. have disclosed the application of hydraulic or pneumatic cylinders to the treadmill.
  • the cushioning apparatus is adjustable.
  • optical detection technique is used to accurately measure the displacement amount of the shock absorption unit when an operator stands on a platform of the treadmill. Accordingly, a corresponding cushioning force of the shock absorption unit can be precisely controlled.
  • the treadmill 10 includes a base frame 20 and a deck frame 30.
  • a handgrip frame 21 extends upwardly from both sides at front end of the base frame 20 with an electronic control panel 22 mounted thereon.
  • the deck frame 30 has a running belt 31 movably mounted thereon so that the operator can stand thereon to take the walking, jogging or running exercise.
  • a cantilever 23 has one end pivotably connected to the lower portion of each of the handgrip frames 21 and the other end pivotably connected to the deck frame 30.
  • a displacement detector 50 and an adjustable cushioning apparatus 40 with a driving motor 41 are interposed between each connecting arm 24 of the handgrip frame 21 and each cantilever 23 for adjusting the cushioning force in accordance with different forces acting on the deck frame 30.
  • an auxiliary supporting rod 25 is interposed between the connecting arm 24 and the base frame 20.
  • the driving motor 41 brings an adjustment gear 43 in rotation through a motor shaft gear 42.
  • the rotation of the adjustment gear 43 enables the adjustment of the cushioning force provided by the adjustable cushioning apparatus 40.
  • a coupling control element 44 is disposed on the adjustment gear 43.
  • the control element 44 is movable with the adjustment gear 43. When the control element 44 contacts one of micro-switches 45, 46, the driving motor 41 is automatically shut down.
  • the displacement detector 50 having a cable 51, a guide roller 52, a large gear 53, a small gear 54 and an optical disk 56 is installed at bottom end of the adjustable cushioning apparatus 40.
  • the optical disk 56 and the small gear 54 are received on a shaft 55.
  • An optical detector 57 is mounted near one side of the optical disk 56.
  • the cable 51 with one end fixed at the connecting arm 24 of the handgrip frame 21 extends around the guide roller 52 and the large gear 53 and is secured to the other end to the base frame 20.
  • the optical detector 57 can determine the displacement amount of the adjustable cushioning apparatus 40.
  • a micro main board 60 serving as a control center is mounted on the adjustable cushioning apparatus 40 for an effective control and connection among the displacement detector 50, the driving motor 41, the micro-switches 45, 46 and the electronic control panel 22.
  • the electric connection thereof it belongs to prior art so that no further descriptions thereto are given hereinafter.
