Patent Application
20240139014
This invention relates to a hinged ankle brace and more particularly to a hinged ankle brace wherein the medial and lateral joints between the foot bed member and the ankle cuff are flexible joint members comprised of polyurethane or like materials. Even more particularly, the flexible joint members create greater resistance to hinged movement of the foot bed member and the ankle cuff thereof as the two members hingedly move to a greater degree with respect to one another. Even more particularly, the flexible joint members and related structure not only permit plantarflexion and dorsiflexion hinged movement between the foot bed member and the ankle cuff but also permit inversion and eversion movement therebetween.
Conventional semi-rigid ankle braces have been previously provided wherein the foot bed member of the ankle brace is pivotally or hingedly movable, about a pair of joints, with respect to the ankle cuff of the brace or vice versa. Normally, each of the prior art joints between the foot bed member and the ankle cuff are simply a pivot pin or bolt. In such braces, the pivotal movement between the foot bed member and the ankle cuff is not a floating movement but is a pivotal movement about a central axis. Further, to the best of Applicant's knowledge, no one has provided a joint for hinged ankle braces which increases the resistance to pivotal movement as the pivotal movement between the foot bed member and the ankle cuff increases. In other words, in the prior art, any resistance to the pivotal movement between the foot bed member and the ankle cuff, if any, remains the same during the entire pivotal movement therebetween.
Applicant's hinged ankle brace of Published Application U.S. 2018/0153724 A1 represents a significant advance in the ankle brace art in that the flexible joint members thereof create greater resistance to hinged movement of the foot bed member and the ankle cuff thereof as the two members hingedly move to a greater degree with respect to one another. However, the flexible joint members of the co-pending application only permit plantarflexion and dorsiflexion movement of the foot bed member and the ankle cuff thereof. Applicant has determined that it is advantageous to also permit some inversion and eversion movement between the foot bed member and the ankle cuff thereof.
