Abstract

A treadmill includes a frame; a running belt configured to move relative the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, the force of rotation of the running belt is provided by a user of the treadmill. In a second operating mode, the motor applies a desired braking force to resist rotation of the running belt. In a third operating mode, the motor applies a torque output to the running belt based on a force exerted on the running belt by a user of the treadmill.

First claim

What is claimed:

1 . A treadmill, comprising:
a frame; a running belt configured to rotate relative the frame; and a motor coupled to the running belt, the motor operable in a plurality of user controlled operating modes such that:
in a first operating mode, the force of rotation of the running belt is provided by a user of the treadmill;
in a second operating mode, the motor applies a desired braking force to resist rotation of the running belt; and
in a third operating mode, the motor applies a torque output to the running belt based on a force exerted on the running belt by a user of the treadmill.

2 . The treadmill of claim 1 , wherein in the second operating mode, the rotation of the running belt is resisted by the desired braking force in one of a first rotational direction of the running belt or in a second rotational directional of the running belt, the second rotational direction being opposite the first rotational direction.

3 . The treadmill of claim 1 , further comprising a front running belt pulley coupled to the frame and a rear running belt pulley coupled to the frame, the front running belt pulley and rear running belt pulley each adapted to at least partially support the running belt.

4 . The treadmill of claim 1 , wherein the running belt defines a substantially planar running surface.

5 . The treadmill of claim 1 , wherein the running belt defines a non-planar running surface.

6 . The treadmill of claim 1 , wherein the desired braking force is a user definable setting, wherein increasing the desired braking force increases a force required by the user to rotate the running belt and decreasing the desired braking force decreases a force required by the user to rotate the running belt.

7 . A treadmill, comprising:
a running belt; and a motor coupled to the running belt, the motor operable in a plurality of operating modes such that:
in a first operating mode, the motor applies a desired braking force to resist rotation of the running belt; and
in a second operating mode, the motor applies a torque output to the running belt based on a force exerted on the running belt by a user of the treadmill.

8 . The treadmill of claim 7 , wherein the motor is operable in a third operating mode, wherein in the third operating mode, rotation of the running belt is provided solely by a user of the treadmill.

9 . The treadmill of claim 8 , wherein in the third operating mode, a holding torque of the motor is disabled to allow the running belt to freely or substantially freely rotate.

10 . The treadmill of claim 9 , wherein in the third operating mode, the running belt moves in a first rotational direction or in a second rotational directional, the second rotational direction being opposite the first rotational direction.

11 . The treadmill of claim 7 , wherein in the second operating mode, the motor rotates the running belt at a desired speed and applies the torque output to compensate for a load applied to the running belt by the user of the treadmill.

12 . The treadmill of claim 7 , further comprising a controller coupled to the motor, wherein in the first operating mode, the controller is configured to receive an exit command to exit the first operating mode, and wherein in the second operating mode, the controller is configured to receive an exit command to exit the second operating mode.

13 . The treadmill of claim 7 , further comprising:
a frame; a front shaft assembly coupled to the frame; and a rear shaft assembly coupled to the frame and spaced apart from the front shaft assembly; wherein the running belt is disposed about the front and rear shaft assemblies.

14 . The treadmill of claim 13 , wherein the motor is coupled to the front shaft assembly, and wherein in the first operating mode, the desired braking force provided by the motor is applied to the front shaft assembly.

15 . The treadmill of claim 13 , wherein the motor is coupled to the rear shaft assembly, and wherein in the second operating mode, the desired braking force provided by the motor is applied to the rear shaft assembly.

16 . The treadmill of claim 7 , wherein the running belt defines a non-planar running surface.

17 . The treadmill of claim 7 , wherein the running belt defines a substantially planar running surface.

18 . A treadmill, comprising:
a frame; a running belt coupled to the frame and adapted to move relative to the frame; and a motor coupled to the running belt, the motor operable in a plurality of operating modes such that:
in a first operating mode, rotation of the running belt is driven by a user of the treadmill; and
in a second operating mode, the motor rotates the running belt at a desired speed and selectively applies a torque output to compensate for a load applied to the running belt by a user of the treadmill.

19 . The treadmill of claim 18 , wherein in a third operating mode, the motor applies a desired braking force to resist rotation of the running belt.

20 . The treadmill of claim 18 , wherein the running belt defines a substantially planar running surface.
