(Preferred arrangement of fixing pieces of further fixing part)
As mentioned above, the ankle joint supporter of the present invention has four fixing parts, so compared to a conventional support made of a cylindrical member, the ankle supporter of the present invention has four more fixing parts. It is possible to fix it in an appropriate state that matches the shape.

By fixing the four fixation points at the instep, the Achilles tendon, the shin, and the long shin, it is possible to efficiently hold the affected area to the maximum extent possible. Furthermore, by adjusting the fixing conditions at the four fixing points, it is possible to optimally adjust the fixing force according to the shape of the wearer's foot. In addition, even if the material of the supporter stretches as a whole due to frequent use, there are four fixation points, so you can adjust the degree of fixation at each fixation point to improve the ankle joint as a whole. It becomes possible to eliminate loosening of the supporter. Furthermore, if the overall shape of the ankle joint supporter is adjusted to some extent to match the shape of the wearer's foot by adjusting the four fixing parts, the ankle joint supporter can be attached and removed by attaching and detaching the pair of fixing pieces of the predetermined fixing parts. It can be performed from the side or from the Achilles tendon side.

Here, it is preferable that the first fixing part has a shape that covers up to the metatarsal part when worn. In this way, the metatarsals are covered, making it possible to more stably fix the instep.

Furthermore, it is preferable that the ankle joint supporter is configured in a shape that allows it to cover from the sole of the foot to the ankle when worn. By doing this, compared to conventional supports that cover the ankle and its upper side, the area around the ankle is held firmly, thereby preventing the ankle joint from moving in and out. .

Moreover, it is preferable that the first fixing part, the second fixing part, the third fixing part, and the fourth fixing part each include a pair of fixing pieces that are located on both left and right sides of the sole and can be fixed to each other. This is because the ankle joint supporter 100 can be easily attached to the calcaneus.

(Preferred arrangement of fixing pieces in the first fixing part and the third fixing part)
One side fixing piece of the first fixing part is arranged at a position where the outside of the foot faces when worn, and the other side fixing piece is arranged at a position where the inside of the foot faces. When wearing the foot, the other side fixing piece, which is placed in a position where the inside of the foot is facing, is wrapped around the other side fixing piece on the inside and the one side fixing piece on the outside, and the one side fixing piece on the outside is placed on the left side of the foot. The third fixing part is attached to the other side fixing piece on the inside to the right side, and further, in the third fixing part, the shin part adjacent to the instep is wrapped with the one side fixing piece on the inside and the other side fixing piece on the outside. It is preferable that the other side fixing piece on the outside is fixed to the one side fixing piece on the inside from the right side of the foot toward the left side.

In this case, the part spanning from the one side fixing piece of the first fixing part that fixes the instep to the one side fixing piece of the third fixing part that fixes the shin, and the other side fixing of the third fixing part that fixes the shin. The part extending from the first fixing part to the other fixing piece intersects between the instep part and the shin part.

In other words, in the first fixing part that fixes the instep part 11, one side fixing piece is located on the outside and the other side fixing piece is located on the inside, and these fixing pieces overlap, whereas the shin part is fixed. In the third fixing portion, one side fixing piece is located on the inside, the other side fixing piece is located on the outside, and these fixing pieces overlap.

As a result, between the instep part and the shin part, the part from the first fixing part to the third fixing part going from the outside to the inside (the connecting part between the one side fixing piece and the other side fixing piece (R1 in FIGS. 1 and 2) (part)) intersects with the part extending from the first fixing part to the third fixing part from the inside to the outside (the connecting part between the other side fixing piece and the other side fixing piece (R2 part in FIGS. 1 and 2)). Become.

As a result, the third fixing part suppresses the loosening of the fixation between the one side fixation piece and the other side fixation piece at the first fixation part, and the fixation between the one side fixation piece and the other side fixation piece at the third fixation part. The first fixing part can suppress the loosening of the first fixing part.

(Preferred arrangement of fixing pieces in the second fixing part and the fourth fixing part)
Similarly, in the second fixation part, the Achilles tendon is wrapped around the Achilles tendon by the one fixation piece on the inside and the other fixation piece on the outside. The fixation piece is attached to the fixation piece, and further, in the fourth fixation part, the calf part adjacent to the Achilles tendon is wrapped with the other side fixation piece on the inside and the one side fixation piece on the outside, and the one side fixation piece on the outside is wrapped around the calf part adjacent to the Achilles tendon. It is preferable to fix it by attaching it to the other fixing piece on the inside from the left side of the foot to the right side.

In this case, from the one side fixation piece of the second fixation part that fixes the Achilles tendon to the one side fixation piece of the fourth fixation part that fixes the calf, and from the other side fixation piece of the second fixation part that fixes the Achilles tendon. The portion of the fourth fixing portion that straddles the other side fixing piece intersects between the Achilles tendon and the calf.

In other words, in the second fixation part that fixes the Achilles tendon, one side fixation piece is located on the inside and the other side fixation piece is located on the outside, and these fixation pieces overlap, whereas the second fixation piece that fixes the calf part is located on the inside and the other side fixation piece is located on the outside. In the four fixing parts, one side fixing piece is located on the outside, the other side fixing piece is located on the inside, and these fixing pieces overlap.

As a result, between the Achilles tendon and the calf, there is a part extending from the second fixation part to the fourth fixation part from the inside to the outside (the connecting part between the one side fixation piece and the other side fixation piece (R3 part in Fig. 1)). , a portion extending from the outside to the inside from the second fixing portion to the fourth fixing portion (the connecting portion between the other fixing piece and the other fixing piece (portion R4 in FIG. 1)) intersects with each other.

As a result, the fourth fixing part suppresses the loosening of the fixation between the one side fixation piece and the other side fixation piece at the second fixation part, and the fixation between the one side fixation piece and the other side fixation piece at the fourth fixation part. The second fixing part can suppress the loosening of the second fixing part.

(stay)
The ankle joint supporter may further include a pair of stays that cover the medial and lateral malleolus of the foot. In this case, by protecting the affected area with the stay, the affected area can be properly preserved, that is, protected, and a high-quality therapeutic effect can be obtained.

Note that the pair of stays can be attached, for example, to both sides of the sole of the foot, or to one side fixing piece and the other side fixing piece of the first fixing part, respectively.

(tightening belt)
Further, the ankle joint supporter may include a tightening belt (taping) that further tightens the affected area from above the ankle joint supporter. By providing a tightening belt, the holding force of the foot joints can be further increased. It is preferable that this tightening belt is worn in a figure eight shape so as to straddle a portion from the arch of the foot to the instep and a portion from the instep to the ankle. In this case, it is possible to fix the area from the sole (arch) of the foot to the calcaneus via the instep with one tightening belt.

Furthermore, it is preferable that a hook-and-loop fastener is provided at the end of the tightening belt. By doing this, the outer material of the tightening belt is made of a material that allows the hook-and-loop fastener to be re-stored, so that the end of the tightening belt attached to the affected area such as the ankle can be placed at any position on the outer material of the tightening belt. It can be fixed with.
