Ankle stabilizing device
View Patent ↗A functional ankle brace is custom tailored to optimize the magnitude and direction of the stiffness and fit of the ankle brace, so as to slow down the inverting motion of the ankle joint enough to allow the muscles enough time to act on their own.
1. An ankle brace, comprising:
a base portion having a lateral edge and an opposing medial edge;
a lateral upright portion extending upwardly from the lateral edge;
a medial upright portion extending upwardly from the medial edge;
a lateral leg member pivotally coupled to the lateral upright portion at a lateral pivot point;
a medial leg member pivotally coupled to the medial upright portion at a medial pivot point;
a lateral tab portion extending rearwardly from the lateral upright portion; and
a medial tab portion extending rearwardly from the medial upright portion;
wherein the lateral tab portion extends rearwardly so as to form a lateral void space below the lateral tab portion;
wherein the medial tab portion extends rearwardly so as to form a medial void space below the medial tab portion; and
a rear portion extending rearwardly from the base portion, the rear portion being configured so as to form the lateral void space between the rear portion and the lateral tab portion and configured to form the medial void portion between the rear portion and the medial tab portion.
2. The ankle brace according to claim 1 , wherein a front portion of the base portion has a tapered front edge.
3. The ankle brace according to claim 2 , wherein the front edge tapers downwardly.
4. The ankle brace according to claim 2 , wherein the base portion is wider at the tapered front edge.
5. The ankle brace according to claim 1 , wherein the base portion further comprises:
a front portion;
a rear portion; and
an arch portion.
6. The ankle brace according to claim 5 , wherein the arch portion forms an arcuate transition between the front portion and the rear portion.
7. The ankle brace according to claim 1 , wherein the medial pivot point is higher than the lateral pivot point.
8. The ankle brace according to claim 1 , wherein the lateral upright portion is anatomically contoured to conform to an outer side of a user's malleoli.
9. The ankle brace according to claim 1 , wherein the medial upright portion is anatomically contoured to conform to an inner side of a user's malleoli.
10. The ankle brace according to claim 1 , further comprising:
a heel portion extending rearwardly from the base portion, the heel portion being concave upward.
11. The ankle brace according to claim 1 , wherein the base portion is shaped to conform to the contours of a user's foot.
12. An ankle stabilizing device, comprising:
a foot plate;
a medial leg member having a longitudinal length, the medial leg member comprising:
a lower medial portion;
a medial tab portion extending rearwardly from the lower medial portion;
an upper medial portion; and
a medial flange extending rearwardly from the upper medial portion;
a lateral leg member having a longitudinal length, the lateral leg member comprising:
a lower lateral portion;
a lateral tab portion extending rearwardly from the lower lateral portion;
an upper lateral portion; and
a lateral flange extending rearwardly from the upper lateral portion; and
a rear portion extending rearwardly from the base portion, the rear portion being configured so as to form the lateral void space between the rear portion and the lateral tab portion and configured to form the medial void portion between the rear portion and the medial tab portion;
wherein the medial leg member and the lateral leg member pivotally engage the foot plate; and
wherein the longitudinal length of the medial leg is different from the longitudinal length of the lateral leg member.
13. The ankle stabilizing device according to claim 12 , further comprising:
an upper strap member for adjustably coupling the upper medial portion to the upper lateral portion, such that the upper medial portion and the upper lateral portion are compressed against a user's leg, the upper strap passing in front of and behind the user's leg.
14. The ankle stabilizing device according to claim 13 , further comprising:
a quick release member connected to the upper strap, the quick release member allowing the adjusted length of the upper strap to remain substantially constant during repeated administration of the ankle stabilizing device.
15. The ankle stabilizing device according to claim 12 , further comprising:
a lower strap member for adjustably coupling the lower medial portion to the lower lateral portion, such that the lower medial portion and the lower lateral portion are compressed against a user's leg, the lower strap passing only in front of the user's leg.
16. The ankle stabilizing device according to claim 15 , further comprising:
a quick release member connected to the lower strap, the quick release member allowing the adjusted length of the lower strap to remain substantially constant during repeated administration of the ankle stabilizing device.
17. The ankle stabilizing device according to claim 12 , wherein the medial flange and the lateral flange are releasably coupled to each other.
18. The ankle stabilizing device according to claim 12 , wherein both the medial flange and the lateral flange are releasably and adjustably coupled to each other.
19. The ankle stabilizing device according to claim 12 , wherein the dimensions and the materials of the foot plate, the medial leg member, and the lateral leg member are selectively chosen, such that the stiffness of the ankle stabilizing device is tailored to slow down the inverting motion of an ankle joint enough to allow muscles of the ankle joint enough time to act to prevent spraining of the ankle joint.
