  • Ankle brace walker
    Patent number: 5620411
    Abstract: Load forces are distributed and reacted along lateral and medial side plates, thereby avoiding the concentration of stresses which could cause cracking, buckling, crippling and the like. This is provided by an intermediate plate portion which has an external edge in the form of an elliptical segment. Because of the elliptical profile of the intermediate side plate portion, shear forces imposed by an applied toe load will be distributed through the intermediate side plate portion, thereby reducing the maximum level of forces imposed at the union of lateral and medial brace members with lateral and medial side plates. The gait pattern of the patient is accommodated by a composite outsole which permits yieldable, bending contact rather than rigid, rolling contact with the ground surface. The composite outsole includes an elongated, flexible shell, a flexible heel core and a flexible foot core, with the flexible heel core and foot core being enclosed within the flexible shell in tandem relation to each other.
    Type: Grant
    Filed: May 27, 1994
    Date of Patent: April 15, 1997
