Abstract

A control system for controlling tension applied to a lace cable coupled to a support structure of an adaptive support garment is discussed herein. The control system can include a lace spool, a damper mechanism, and a locking ring. The lace spool can include a lace groove to receive the lace cable and a rotary bias member to apply rotational tension to resist extension of the lace cable out of a housing holding the control system. The damper mechanism is engagable with the lace spool to generate an additional rotational tension resisting extension of the lace cable out of the housing. The locking ring is frictionally coupled to the lace spool, and the locking ring can include a lock wedge adapted to disengage the damper mechanism upon rotation into a pre-determined rotational position relative to the damper mechanism.

First claim

The invention claimed is:

1 . A method of controlling a lace cable coupled to a support structure within an adaptive support garment, the method comprising:
applying, using a control system, a first tension to resist extension of the lace cable out of a housing the control system; engaging a control mechanism within the control system upon extraction of a portion of the lace cable from the housing of the control system; and applying, using the control system, a second tension to resist extension of the lace cable out of the housing; wherein the applying the first tension includes a rotary bias member within a lace spool of the control system applying a rotatory tension on the lace cable via the lace spool; the engaging the control mechanism includes pivoting a damper mechanism into engagement with the lace spool; and the pivoting the damper mechanism into engagement includes removing a locking wedge on a locking ring coupled to the lace spool from engagement with the damper mechanism.

2 . The method of claim 1 , wherein the pivoting the damper mechanism into engagement includes a drive gear on the damper mechanism meshing with a spool gear on the lace spool.

3 . The method of claim 1 , wherein applying the second tension includes activating a rotary damper portion of the control mechanism to increase a rotary tension resisting extension of the lace cable.

4 . The method of claim 1 , further comprising disengaging the control mechanism upon retraction of a second portion of the lace cable back onto a lace spool within the control system.

5 . The method of claim 4 , wherein the disengaging the control mechanism includes rotating a lock wedge portion of a locking ring frictionally coupled to the lace spool into a position that pivots the control mechanism away from the lace spool.

6 . A method of operating an analog control system within an adaptive support garment, the method comprising:
applying a first tension on a lace cable using a rotary bias member coupled to a lace spool; engaging a damper mechanism upon extension of a pre-defined length of the lace cable from the lace spool; and applying a second tension on the lace cable upon engaging of the damper mechanism; and disengaging the damper mechanism upon retraction of a second portion of the lace cable back onto a lace spool within the analog control system; wherein the disengaging the damper mechanism includes rotating a lock wedge portion of a locking ring frictionally coupled to the lace spool into a position that pivots the damper mechanism away from the lace spool.

7 . The method of claim 6 , wherein the engaging the damper mechanism includes pivoting the damper mechanism into engagement with the lace spool.

8 . The method of claim 7 , wherein the pivoting the damper mechanism into engagement includes removing a locking wedge on a locking ring coupled to the lace spool from engagement with the damper mechanism.

9 . The method of claim 7 , wherein the pivoting the damper mechanism into engagement includes a drive gear on the damper mechanism meshing with a spool gear on the lace spool.

10 . The method of claim 6 , wherein applying the second tension includes activating the damper mechanism to increase a rotary tension resisting extension of the lace cable.

11 . A method for controlling tension applied to a lace cable coupled to a support structure of an adaptive support garment, the method comprising:
applying a first tension on the lace cable wrapped around a lace spool to resist extension of the lace cable off the lace spool; rotating the lace spool in a first direction in response to the first tension; maintaining disengagement with a damper mechanism from the lace spool while the lace spool rotates in the first direction; applying a second tension on the lace cable; rotating the lace spool in a second direction in response to the second tension; and engaging the damper mechanism in response to rotation of the lace spool in the second direction; wherein maintaining disengagement of the damper mechanism includes engagement of a lock wedge on a locking ring to pivot the damper mechanism away from the lace spool.

12 . The method of claim 11 , wherein engaging the damper mechanism includes rotating the locking ring to disengage the lock wedge and allow the damper mechanism to pivot into engagement with the lace spool.

13 . The method of claim 11 , wherein the second direction is opposite the first direction.

14 . The method of claim 11 , wherein engaging a drive gear of the damper mechanism with a spool gear coupled to the lace spool to apply a third tension on the lace cable to resist extension of the lace cable off the lace spool.
