Abstract

A wrist brace comprises (a) a main brace body, (b) an adjustable wrist strap configured to encircle the main brace body about a wearer's wrist, and (c) a lace and rotatable tightening mechanism. The main brace body comprises a semi-rigid splint configured to fit the anterior of a wearer's wrist, extending from the palm to a portion of the anterior of the forearm. The lace and tightening rotatable mechanism is configured to apply tension on the lace thereby tightening the wrist strap about the wearer's wrist and drawing the splint closer to the anterior of the wearer's wrist.

First claim

I claim:

1. A wrist brace comprising:
a main brace body comprising a semi-rigid splint configured to fit the anterior of a wearer's wrist, the splint configured to extend from the palm to a portion of the anterior of the forearm and disposed at least partially within the main brace body, wherein the main brace body comprises first and second opposing sides that, during use, are drawn towards each other on the posterior of the wearer's wrist and forearm, the opposing sides each having an upper portion and a lower portion;
a first tightening system disposed on an upper portion of the main brace body for tightening the upper portions, the first tightening system comprising a first lace, a first lace guide, a first rotatable tightening mechanism, and a lace retainer mounted to the brace body, wherein the first lace guide is disposed on a side of the brace body opposite the first rotatable tightening mechanism and lace retainer; and
a second tightening system disposed on a portion of the main brace body proximal to the first tightening system for tightening the lower portions, the second tightening system comprising a second lace, a second lace guide, and a second rotatable tightening mechanism, wherein the second tightening system further comprises a third lace guide disposed on the main brace body proximal to the second lace guide, and wherein the second and third lace guides are disposed on a side of the brace body opposite the second rotatable tightening mechanism;
wherein the second lace is threaded through both the second and third lace guides and is secured to both the first and second rotatable tightening mechanisms, such that when the second rotatable tightening mechanism applies tension on the second lace, the lower portions are advanced towards each other.

2. The wrist brace of claim 1 , wherein each tightening mechanism and the lace retainer are disposed on the first side of the main brace body, and wherein the lace guides are disposed on the second side of the main body.

3. The wrist brace of claim 1 , wherein the first rotatable tightening mechanism is disposed on the first side of the main brace body at a location between the first lacing guide and the second lacing guide.

4. The wrist brace of claim 1 , wherein the first lace is threaded through the first lace guide, is secured at one end to the first tightening mechanism and secured at another end to the lace retainer, such that when the first rotatable tightening mechanism applies tension on the first lace, the upper portions are advanced towards each other.

5. The wrist brace of claim 1 , wherein the main brace body includes a defined receptacle, and wherein the splint is received in the receptacle.

6. The wrist brace of claim 5 , wherein the main brace body includes a defined pocket, and wherein the splint is received in the pocket.

7. The wrist brace of claim 1 , wherein the splint is removable.

8. The wrist brace of claim 1 , wherein the splint is disposed only on the anterior of the wearer's wrist during use.

9. The wrist brace of claim 1 and further comprising a tongue configured to be positioned beneath and between the opposing sides of the main brace body when the wrist brace is closed.

10. The wrist brace of claim 1 wherein the main brace body comprises a combination of foam laminate and spacer fabric as the primary outer surface.

11. The wrist brace of claim 1 , wherein the tightening mechanism comprises a mechanism of release for disengaging the tightening mechanism.

12. The wrist brace of claim 1 , wherein the splint comprises aluminum.

13. The wrist brace of claim 1 , wherein the main brace body comprises a spacer fabric as a primary outer surface.

14. The wrist brace of claim 1 wherein the main brace body comprises rip-stop nylon as the primary outer surface.

15. The wrist brace of claim 1 , wherein the main brace body comprises a nylon fabric of 70 denier or higher as a primary outer surface.
