Abstract (en)
A treadmill having two handgrip frames, a base frame (20) and a deck frame (30) includes a displacement detector (50) of a shock absorption unit. 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 of the handgrip frame (21) and each cantilever for adjusting the cushioning force. The displacement detector (50) having a cable, a guide roller (52), a large gear (53), a small gear (54) and an optical disk is installed at bottom end of the adjustable cushioning apparatus (40). The optical disk and the small gear are received on a shaft. An optical detector is mounted near one side of the optical disk. The cable with one end fixed at the connecting arm of the handgrip frame extends around the guide roller (52) and the large gear (53) and is secured to the other end to the base frame (20).
