Abstract

The disclosure relates to medical braces having lacing systems for tightening of the medical braces. Some embodiments include multiple components of the lacing system integrated into a single housing piece. For example, multiple reels can be used to tighten different portions of the lacing system, and the multiple reels can be mounted onto a single housing. Also, multiple lace guides can be integrated into, or attached to, a single housing piece.

First claim

What is claimed is:

1. A medical brace comprising:
a main body configured to be worn by a user; and
a lacing system configured to tighten and loosen the main body, the lacing system comprising:
a first reel configured to rotate about a first axis to tighten a first portion of the lacing system;
a second reel configured to rotate about a second axis different than the first axis to tighten a second portion of the lacing system; and
a first unitary housing piece coupled to the body and configured to house and connect both the first reel and the second reel, wherein the medical brace is configured to restrict movement of a portion of the user anatomy.

2. The medical brace of claim 1 , wherein the lacing system further comprises a plurality of lace guides mounted onto a second housing piece.

3. The medical brace of claim 2 , wherein the second housing piece is substantially rigid and configured to provide substantially rigid support to the medical brace.

4. The medical brace of claim 2 , wherein the first housing piece is substantially rigid and is configured to provide substantially rigid support to the medical brace, and wherein the medical brace does not include any rigid support member other than the first housing piece and the second housing piece.

5. The medical brace of claim 2 , wherein the medical brace comprises a first side and a second side that are configured to be drawn together by tightening the lacing system, wherein the first reel and second reel are positioned on the first side of the medical brace, and wherein the plurality of lace guides are positioned on the second side of the medical brace.

6. The medical brace of claim 1 , wherein the first housing piece is substantially rigid and is configured to provide substantially rigid support to the medical brace.

7. The medical brace of claim 6 , wherein the medical brace does not include any rigid support member other than the housing piece.

8. The medical brace of claim 1 , wherein the second reel is positioned adjacent to the first reel.

9. The medical brace of claim 1 , wherein the medical brace is a wrist brace.

10. The medical brace of claim 1 , wherein the medical brace is an ankle brace.

11. The medical brace of claim 1 , wherein the first axis and the second axis are substantially parallel.

12. The medical brace of claim 1 , wherein the first reel includes a first reel housing, the second reel includes a second reel housing, and wherein the first and second reel housing are coupled to or integral with the first housing piece.

13. The medical brace of claim 1 , wherein at least a portion of the first housing piece comprises a material that is softer or harder than the reel.

14. A medical brace comprising:
a main body configured to be worn by a user; and
a lacing system configured to tighten and loosen the main body, the lacing system comprising:
a lace;
a plurality of lace guides configured to provide a lace path for the lace, wherein a first guide of the plurality of lace guides comprises a first opening and a second opening and a lace channel extending between the first opening and the second opening, wherein a second guide of the plurality of lace guides comprises a first opening, a second opening, and a lace channel extending between the first opening and the second opening, and wherein the second opening of the first guide and the first opening of the second guide are positioned between the first opening of the first guide and the second opening of the second guide;
a first reel configured to rotate about a first axis to tighten a first portion of the lacing system;
a second reel configured to rotate about a second axis different than the first axis to tighten a second portion of the lacing system;
a first unitary housing piece coupled to the body, and configured to house and connect both the first reel and the second reel; and
a second unitary housing piece supporting the plurality of lace guides, wherein the medical brace is configured to restrict movement of a portion of the user anatomy.

15. The medical brace of claim 14 , wherein the second housing piece is substantially rigid and is configured to provide substantially rigid support to the medical brace.

16. The medical brace of claim 15 , wherein the first housing piece is substantially rigid and is configured to provide substantially rigid support to the medical brace, and wherein the medical brace does not include any rigid support member other than the first housing piece and the second housing piece.

17. The medical brace of claim 14 , wherein the medical brace comprises a first side and a second side that are configured to be drawn together by tightening the lacing system, wherein the plurality of lace guides are positioned on the first side of the medical brace, and wherein no additional lace guides are positioned on the first side of the medical brace.

18. The medical brace of claim 14 , wherein the plurality of lace guides are spaced apart from each other with portions of the second, unitary housing piece extending between the lace guides.

19. The medical brace of claim 14 , wherein the plurality of lace guides are arranged generally linearly along a side of the medical brace.

20. The medical brace of claim 14 , wherein the first reel includes a first reel housing, the second reel includes a second reel housing, and wherein the first and second reel housing are coupled to or integral with the first housing piece.

21. The medical brace of claim 14 , wherein at least a portion of the first housing piece comprises a material that is softer or harder than the reel.
