Abstract

A clutch mechanism includes a spool that is configured to receive a cable, a disk with elasticity, a mechanism configured for locking and unlocking the movement of the disk, and at least one sensor. The at least one sensor being configured to measure the movement of at least one of the disk and the spool in the unlocked mode and to measure the movement of the spool relative to the disk when in a locked mode.

Claims (26)

1 . A clutch mechanism comprising: a spool that is configured to receive a cable, a disk with elasticity, a mechanism configured for locking and unlocking the movement of the disk, and at least one sensor for measuring the movement of at least one of the disk and the spool in an unlocked mode and for measuring the movement of the spool relative to the disk when in a locked mode,

wherein the mechanism configured for locking and unlocking the disk for movement includes at least one ball bearing, at least one cam plunger, and at least one actuator.

2 . The clutch mechanism of claim 1 , wherein the disk has rotational elasticity, the mechanism configured for locking and unlocking the disk for rotational movement, and the at least one sensor for measuring the rotational movement of at least one of the disk and the spool in the unlocked mode and for measuring the rotational movement of the spool relative to the disk when in a locked mode.

3 . The clutch mechanism of claim 2 , wherein the disk includes an inner ring, an outer ring, and a plurality of spokes extending therebetween.

4 . The clutch mechanism of claim 3 , wherein the outer ring of the disk includes an exterior surface, the exterior surface of the outer ring forming a plurality of detents.

5 . The clutch mechanism of claim 4 , wherein the plurality of detents is from about 10 to about 180.

6 . The clutch mechanism of claim 5 , wherein the plurality of detents is from about 20 to about 100.

7 . The clutch mechanism of claim 1 further including a spool cap, the spool cap being located between the disk and the spool.

8 . The clutch mechanism of claim 1 further including a spring mechanism, the spring mechanism being received into an opening formed in the spool.

9 . The clutch mechanism of claim 8 , wherein the spring mechanism includes a power spring.

10 . The clutch mechanism of claim 1 , wherein the mechanism configured for locking and unlocking the disk for movement includes a plurality of ball bearings, a plurality of cam plungers, and a plurality of actuators.

11 . The clutch mechanism of claim 1 , wherein the at least one actuator is a pull latching solenoid.

12 . The clutch mechanism of claim 1 , wherein the at least one sensor is a magnetic sensor, and the clutch mechanism further includes a magnet.

13 . The clutch mechanism of claim 1 further including the cable, and wherein the spool forms a groove on an exterior surface thereof for receiving the cable.

14 . The clutch mechanism of claim 1 further including a support plate with at least one axis extending outwardly therefrom.

15 . The clutch mechanism of claim 14 , wherein the support plate includes a plurality of axes extending outwardly therefrom.

16 . A wearable assist device in combination with the clutch mechanism of claim 1 .

17 . The clutch mechanism of claim 1 , wherein the at least one actuator is a pulled tubular solenoid, a push tubular solenoid, a rotary solenoid, or an electric motor.

18 . A clutch mechanism comprising: a spool that is configured to receive a cable, a disk with rotational elasticity that includes a plurality of detents formed on an exterior surface thereof, a spring mechanism being received into an opening formed in the spool, at least one ball bearing, at least one cam plunger, at least one solenoid, and at least one sensor for measuring the rotational movement of at least one of the disk and the spool in an unlocked mode and for measuring the rotational movement of the spool relative to the disk when in a locked mode,

wherein the plurality of detents, the at least one ball bearing, the at least one cam plunger, and the at least one solenoid assists in locking and unlocking the disk for rotational movement.

19 . The clutch mechanism of claim 18 , wherein the disk includes an inner ring, an outer ring, and a plurality of spokes extending therebetween.

20 . A method of using a clutch mechanism, the method comprising:

providing a spool that is configured to receive a cable, a disk with elasticity, a mechanism configured for locking and unlocking the movement of the disk, and at least one sensor;

measuring the movement of at least one of the disk and the spool in an unlocked mode via the at least one sensor, and

measuring the movement of the spool relative to the disk when in a locked mode via the at least one sensor,

wherein the mechanism configured for locking and unlocking the disk for movement includes at least one ball bearing, at least one cam plunger, and at least one actuator.
