BACKGROUND OF THE INVENTION CROSS REFERENCE TO RELATED APPLICATION

This is a Continuation-ln-Part application of application Serial No.

13/871 ,094 filed April 26, 2013 entitled ANKLE BRACE, which is a Continuation-ln- Part application of Serial No. 13/134,087, filed May 27, 2011 entitled ANKLE BRACE, now U.S. Patent No. 8,657,773, issued February 25, 2014.

FIELD OF THE INVENTION

This invention relates to an ankle brace and more particularly to an ankle brace including a tensioning system which functionally stabilizes the ankle as it reaches extreme ranges of motion. Even more particularly, this invention relates to an optional ankle strap system which may be used to further stabilize the ankle. DESCRIPTION OF THE RELATED ART

Conventional braces for protecting joints of the body do so by restricting or limiting motion of the joint to which it is applied to prevent a new injury or to protect a pre-existing injury. An ankle joint, just like all the joints in the human body, has a natural range of motion that it can move through without causing damage to itself. As it reaches the end of these ranges, the body has structure such as ligaments and tendons to create tension to end range of motion and protect the joint. Many of the prior art ankle braces do prevent the ankle from exceeding its extreme ranges of motion but do not provide the necessary flexibility to permit the athlete to function normally.

Applicant's ankle brace described and shown in the co-pending application and the issued patent, represent improvements in the ankle brace art. The instant invention represents a further improvement in the ankle brace art.

The hook fasteners 172 on the ankle strap portion 168 are then adjustably secured to the loop fasteners on strap 1 12 at the lateral side thereof as seen in Fig. 5.

As seen in Fig. 2, the ankle strap portion 170 is folded over at 180 and maintained in the folded position by a grommet 182. Ankle strap portion 170 extends beneath the sole 14, thence upwardly over the shoe 12 and towards the medial side of the shoe, thence adjacent the lateral side of the shoe, thence upwardly and rearwardly towards the medial side of strap 1 12. The hook fasteners on the free end 160 of ankle strap 112 are then adjustably secured to the loop fasteners on strap 148 and strap 112. The ankle strap 158 could be used on an ankle brace which does not have the lateral and medial tensioning cords and does not have the straps 148 and 154.

In use, the brace 10 is positioned on the shoe as generally shown in Figs. 3-6. At this time, the lace connecting the eyelets on strap 112 is not tied, and the straps 148 and 154 are not connected to strap 112. The shoe lace 28 is threaded through some of the lower lace openings or eyelets 26 and through at least some of the eyelets 48 of lateral portion 36 and through some of the eyelets 74 of medial portion 56. The shoe lace 28 is then threaded through the remaining eyelets 26 and tied at the upper end of the shoe 12.

A lace member is then threaded through the eyelets 118, 120 at end 114 of strap 112 and through the eyelets 122 and 124 at end 116 of strap 112. The lace member is then tightened and tied. The strap 110 is then secured to the strap 100 at end 104 thereof. The free end of strap 148 is then adjustably secured to strap 112 at the second end thereof. The free end of strap 154 is then adjustably secured to strap 112 at the first end thereof.

The ankle brace 10 permits the ankle of the person to move through its natural range of motion either laterally, medially, fore and aft. When the ankle moves towards the end of its normal range of motion, the tensioning cords 140 and 146 resist further motion to protect the ankle. Ankle support is also provided by the lateral and medial portions 36 and 56. Ankle support is also provided by the flexible and stretchable member 92 which enables the person's ankle to move through its normal range of motion.

If additional support is needed beyond that which is provided by the ankle brace 10, the ankle strap 158 will be utilized. The strap 88 is disconnected from the loop fasteners 84. The strap 88 is then threaded through slits 164 and 166 of ankle strap 158. The free end of strap 88 is then secured to the loop fasteners 84. Ankle strap member 168 is then extended forwardly along lateral portion 38, thence downwardly and laterally beneath the sole 14 of shoe 12 towards the medial side 32 of shoe 12, thence upwardly, thence laterally towards lateral side 30 of shoe 12, thence upwardly and rearwardly adjacent lateral portion 36 towards the first end of strap 112. The free end of ankle strap member 158 is adjustably secured to strap 154 and strap 112.

Ankle strap member 170 is then extended forwardly along medial portion 56, thence downwardly and laterally beneath the sole 14 of shoe 12 towards the lateral side 30 of shoe 12, thence upwardly, thence laterally towards medial side 32 of shoe 12, thence upwardly and rearwardly adjacent medial portion 56 towards the second end of strap 112. The free end of ankle strap member 160 is adjustably secured to strap 148 and strap 112.

Thus it can be seen that the invention accomplishes at least all of its stated objectives.
