Abstract

Claims (13)

1 . An ankle foot orthosis device comprising:

a strut member having an extension portion and footplate portion, wherein the strut member includes a track portion extending along a first side of the extension portion, wherein the extension portion extends up generally perpendicular from the footplate portion;

a housing member having a cavity formed therethrough configured to house a portion of the extension portion of the strut member, wherein the housing member can move from a first position along the track portion to a second position along the track portion, wherein the track portion includes a lower stop member configured to prevent the housing member from traveling past a pre-determined distance along the extension portion, and wherein the housing member includes one or more locating apertures;

an adjustable cuff member, wherein the adjustable cuff member includes a padded portion and a fastening band; and

a locking mechanism, wherein the locking mechanism is coupled to the housing member and configured to interface with the track portion to lock the housing member at one or more positions along the track portion,

wherein the locking mechanism comprises a first surface, a second surface, a first side, second side, a third side, and a fourth side, wherein a first coupling member is formed along the first side and a second coupling member is formed along the third side, wherein the first coupling member and second coupling member are configured to interface with the housing member by approximating an edge of the housing member and wrapping around the edge of the housing member to interface with a second side of the housing member, wherein the track portion includes a plurality of engagement members configured to interface with the locking mechanism and lock the housing member at the one or more positions along the track portion, wherein the first surface of the locking mechanism further includes a first interfacing member and one or more locating members, wherein the first interfacing member is configured to interface with one or more engagement members of the plurality of engagement members and the one or more locating members is configured to interface with the one or more locating apertures.

2 . The device of claim 1 , further comprising a curved portion, wherein the curved portion is configured to approximate the radius of a user's ankle and connects the foot plate portion to the extension portion.

3 . The device of claim 1 , wherein the fastening band is configured to wrap around a first side of the housing member, exterior walls of the adjustable cuff member of the user's leg and is configured to secure the ankle foot orthosis device to the user's leg.

4 . The device of claim 1 , further comprising a secondary support member removably coupled to the track portion.

5 . The device of claim 4 , wherein the secondary support member includes a housing portion configured to be removably couplable to the track portion.

6 . The device of claim 5 , wherein the housing portion includes an interior cavity configured to conform to the dimensions of the extension portion and track portion to limit lateral and rotational movement of the housing portion.

7 . The device of claim 6 , wherein the secondary support member further includes a flange portion.

8 . The device of claim 1 , wherein the adjustable cuff member is capable of being incorporated into a portion of a knee brace.
