Knee brace hinge deflector
View Patent ↗A knee brace hinge deflector is provided for preventing interference and/or locking of the medial hinges of bilateral knee braces. The hinge deflector includes a shell having rounded surfaces for encasing a first medial hinge assembly and deflecting a second medial hinge assembly of bilaterally worn knee braces.
1. A knee brace, comprising:
an upper portion;
a lower portion;
a plurality of straps for securing said upper portion to a person's thigh and said lower portion to a person's calf;
medial and lateral hinges for pivotally coupling said upper and lower portions together; and
a hinge deflector adapted to be worn between the person's knee and said medial hinge, said hinge deflector having an inner side adapted for facing the knee and an outer side opposite from the inner side and facing said medial hinge, said outer side being formed with a first projection extending around a front edge of said medial hinge, said projection having a curved surface along a front edge of said hinge deflector, said curved surface sloping in a rearward direction from said inner side of said hinge deflector toward an outer side of said medial hinge for deflecting an object away from said medial hinge.
2. The brace of claim 1 , wherein said outer side of said hinge deflector is formed with a recess shaped for receiving at least a portion of said medial hinge.
3. The brace of claim 1 , wherein said outer side of said hinge deflector further comprises a second projection extending away from the knee and around a rear edge of said medial hinge.
4. The brace of claim 3 , wherein said second projection is positioned for contacting said upper and lower portions of the knee brace for limiting rotational movement of said medial hinge during flexion of the person's knee.
5. The brace of claim 1 , wherein said hinge deflector is made of a molded plastic material.
6. The deflector of claim 1 , further comprising a plurality of ribs along said inner side of said hinge deflector for increasing the structural integrity of said hinge deflector.
7. A medial hinge deflector having a shell configured to be positioned between a person's knee and a medial hinge of a knee brace, said shell having an inner side shaped for facing a medial portion of the person's knee and an outer side opposite from said inner side and facing said medial hinge, said outer side including a first projection extending around a front edge of the medial hinge, said first projection being formed with a curved surface sloping in a rearward direction from said inner side of said shell toward an outer side of said medial hinge, for deflecting an object away from the medial hinge.
8. The deflector of claim 7 , wherein said outer side of said shell further comprises a recess shaped for receiving a portion of the medial hinge.
9. The deflector of claim 7 , wherein said shell includes a plurality of openings for receiving fasteners to connect said shell to the knee brace.
10. The deflector of claim 7 , wherein said shell is made of a molded plastic material.
11. The deflector of claim 7 , wherein said outer side further comprises a second projection adapted to extend around a rear edge of the medial hinge, said second projection having a curved deflecting surface and being positioned to limit a range of motion of the medial hinge.
12. The deflector of claim 7 , further comprising a plurality of ribs along said inner side for increasing the structural integrity of said shell.
13. The deflector of claim 7 , wherein said shell has a substantially elliptical shape.
14. The deflector of claim 8 , wherein said recess has a substantially elliptical shape.
15. A knee brace, comprising:
an upper portion;
a lower portion;
a plurality of straps for securing said upper portion to a person's thigh and said lower portion to a person's calf;
medial and lateral hinges for pivotally coupling said upper and lower portions together; and
a hinge deflector adapted to be worn between the person's knee and said medial hinge, said hinge deflector having a contoured inner side configured for facing a medial portion of the person's knee and an outer side opposite from said inner side facing said medial hinge, said outer side being formed with a recess for receiving at least a portion of said medial hinge and including a first projection extending around a front edge of said medial hinge, said projection having a curved surface sloping in a rearward direction from said inner side of said hinge deflector toward an outer side of said medial hinge for deflecting an object away from said medial hinge.
16. The brace of claim 15 , wherein said outer side of said hinge deflector further comprises a second projection extending away from the knee and around a rear edge of said medial hinge, said second projection being positioned for contacting said upper and lower portions of the knee brace for limiting rotational movement of said medial hinge during flexion of the person's knee.
17. The brace of claim 16 , wherein said hinge deflector is made of a molded plastic material.
