Hinged ankle brace

Abstract

A hinged ankle brace including a foot bed member and an ankle cuff which are hinged together by flexible joint members. The flexible joint members yieldably resist hinged movement between the foot bed member and the ankle cuff in a plantarflexion and dorsiflexion direction. The design of the upper ends of the medial and lateral wings of the foot bed member and the ankle cuff permit a limited amount of inversion and eversion movement between the foot bed member and the ankle cuff.

Description

BACKGROUND OF THE INVENTION

Field of the Invention

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.

Description of the Related Art

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.

The lower end of the lateral wing of the ankle cuff has radially spaced-apart first, second and third curved slots formed therein. The lower end of the lateral wing of the ankle cuff has a central section with a central opening formed therein. Radially spaced-apart first, second and third pin members extend inwardly from the inner side of the lower end of the lateral wing of the ankle cuff.

The inner side of the lower end of the medial wing of the ankle cuff is positioned outwardly of the outer side of the upper end of the medial wing of the foot bed member. The inner side of the lower end of the lateral wing of the ankle cuff is positioned outwardly of the outer side of the upper end of the lateral wing of the foot bed member.

A flat flexible medial joint member is positioned between the lower end of the medial wing of the ankle cuff and the upper end of the medial wing of the foot bed member. The flexible medial joint member includes a central base portion having radially spaced-apart first, second and third pin openings formed therein. The base portion of the flexible medial joint member has a central opening formed therein. The flexible medial joint member has radially spaced-apart first, second and third arms with inner and outer ends, extending outwardly from the base portion thereof. Fourth, fifth and sixth pin openings are formed in the outer ends of the first, second and third arms respectively.

As stated, the flexible medial joint member is positioned at the inner side of the lower end of the medial wing of the ankle cuff. When so positioned, the first, second and third pin members, which extend inwardly from the inner side of the lower end of the medial wing of the ankle cuff, are received in the fourth, fifth and sixth pin openings in the flexible medial joint member respectively. In that position, the first, second and third pin openings in the flexible medial joint member register with the first, second and third slots formed in the lower end of the medial wing of the ankle cuff and the central opening in the base portion of the flexible medial joint member registers with the central opening formed in the central section of the lower end of the medial wing of the ankle cuff. A connector element, such as a rivet or the like, extends through the central opening in the lower end of the medial wing of the ankle cuff, through the central opening in the base portion of the flexible medial joint member and through the central opening in the central section of the upper end of the medial wing of the foot bed member to hingedly connect the medial wing of the foot bed member to the medial wing of the ankle cuff.

A flexible lateral joint member is positioned between the lower end of the lateral wing of the ankle cuff and the upper end of the lateral wing of the foot bed member. The flexible lateral joint member includes a central base portion having radially spaced-apart first, second and third pin openings formed therein. The base portion of the flexible lateral joint member has a central opening formed therein. The flexible lateral joint member has first, second and third arms with inner and outer ends, extending outwardly from the base portion thereof. Fourth, fifth and sixth pin openings are formed in the outer ends of the first, second and third arms respectively.

As stated, the flexible lateral joint member is positioned at the inner side of the lower end of the lateral wing of the ankle cuff. When so positioned, the first, second and third pin members, which extend inwardly from the inner side of the lower end of the lateral wing of the ankle cuff, are received in the fourth, fifth and sixth pin openings in the flexible lateral joint member respectively. In that position, the first, second and third pin openings in the flexible lateral joint member register with the first, second and third slots formed in the lower end of the lateral wing of the ankle cuff and the central opening in the base portion of the flexible lateral joint member registers with the central opening formed in the central section of the lower end of the lateral wing of the ankle cuff. A connector element, such as a rivet or the like, extends through the central opening in the lower end of the lateral wing of the ankle cuff, through the central opening in the base position of the flexible lateral joint member and through the central opening in the central section of the upper end of the lateral wing of the foot bed member to hingedly connect the lateral wing of the foot bed member to the lateral wing of the ankle cuff.

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 in a plantarflexion and dorsiflexion direction. The outwardly curved inner sides of the lower ends of the medial and lateral wings of the ankle cuff and the outwardly curved outer sides of the upper ends of the medial and lateral wings of the foot bed member also permit a limited amount of inversion and eversion movement between the foot bed member and the ankle cuff. As seen in the drawings, the ankle brace of this invention is preloaded with some dorsiflexion. However, the ankle brace may be easily preloaded with plantarflexion.

A second embodiment of the hinged ankle brace of this invention is also illustrated and described. In the second embodiment, the outer sides of the upper ends of the medial and lateral wings of the foot bed member are outwardly curved. In the second embodiment, the outer sides of the lower ends of the medial and lateral wings of the ankle cuff are not outwardly curved or domed but are flat.

At least one strap is attached to the ankle cuff which is configured to secure a wearer's lower calf thereto.

It is therefore a principal object of the invention to provide an improved hinged ankle brace.

A further object of the invention is to provide a hinged ankle brace wherein the foot bed member of the ankle brace is hingedly connected to the ankle cuff of the ankle brace wherein the joint members between the foot bed members and the ankle cuff are comprised of a flexible material wherein the resistance to the hinged movement between the foot bed member and the ankle cuff increasingly resists the hinged movement of the two members as the hinged movement of the two members increases.

A further object of the invention is to provide a hinged ankle brace which not only permits a limited amount of plantarflexion and dorsiflexion movement between the ankle cuff and the foot bed member but also permits a limited amount of inversion and eversion movement therebetween.

These and other objects will be apparent to those skilled in the art.
