Abstract
A treadmill includes a base frame and an one-way damping device. The one-way damping device includes a rotatable braking plate, an one-way clutch, and a resistance unit. The resistance unit is fixedly mounted to the base frame and abuts against the braking plate. The one-way clutch is sleeved on one of two rotating shafts of the base frame, is not engaged with the braking plate when the rotating shafts are rotated in a first rotational direction, and is engaged with the braking plate when the rotating shafts are rotated in a second rotational direction, which in turn drives the braking plate to co-rotate against a frictional force between the braking plate and the resistance unit.
Claims14
A treadmill comprising:
- a base frame including
- a frame body that has a front end portion and a rear end portion opposite to said front end portion in a front-rear direction, and
- two rotating shafts that are respectively mounted to said front and rear end portions of said frame body, each of said rotating shafts being rotatable relative to said frame body about a rotational axis which extends in a left-right direction transverse to the front-rear direction;
- a treadmill belt trained on said rotating shafts and having a top section that is defined between top ends of said rotating shafts, said top section
- being rearwardly movable around said rotating shafts to drive each of said rotating shafts to rotate about the rotational axis in a first rotational direction, and
- being forwardly movable around said rotating shafts to drive each of said rotating shafts to rotate about the rotational axis in a second rotational direction which is opposite to the first rotational direction;
- and
- an one-way damping device including
- a braking plate that is rotatable about a rotational axis extending in the left-right direction,
- an one-way clutch that is sleeved on the one of said rotating shafts, that is not engaged with said braking plate when said top section of said treadmill belt is moved rearwardly, and that is engaged with said braking plate when said top section of said treadmill belt is moved forwardly such that rotation of the one of said rotating shafts in the second rotational direction drives said braking plate to rotate in the second rotational direction via said one-way clutch, and
- a resistance unit that is fixedly mounted to said frame body and that abuts against said braking plate so that, when said top section of said treadmill belt is moved forwardly, said braking plate is rotated in the second rotational direction against a frictional force between said braking plate and said resistance unit.
