The edges 12 are overlapped and fastened together by hook and loop fasteners 13, 14. As a result, the main body 1 wraps around the lower leg and the ankle joint, and the foot 81 is slightly exposed from the opening 11 of the main body 1 and the heel 82 is exposed from the rear of the main body. Next, the projections 21, 31 of the side support plates 2, 3 are fitted into the slits 42, 43 of the front shell portion 4 in advance and are integrally formed. The side strut plates 2, 3 are positioned so that the side strut plates 2, 3 are located on the sides of the lower leg, respectively, and the hinge portions at the lower ends of the side strut plates 2, 3 are located on the sides of the ankles. The backside fasteners 24, 3
4 and fixed to the surface of the main body 1. Then belt 4
7 and 48, respectively, are rotated backward, one free belt, for example, the free end of the belt 47 is engaged with the surface fastener 411 on the surface of the main body 1 and the free end of the other belt 48 is placed on the belt 47. By engaging with the hook-and-loop fastener 412, the side support plates 2, 3, the front shell part 4, and the belts 47, 48 are securely fixed on the main body 1. Next, a substantially central portion of the sole belt 7 is brought into contact with a bottom portion of the main body 1 and both ends are turned upward from left and right.
6 is fixed on the surface fasteners 55 and 65. The lower side support members 5 and 6 are provided with surface fasteners 56 and 66 on the back surface thereof.
Thus, it is fixed to the surface of the main body 1. At this time, the connection position and angle of the sole belt with respect to the lower side support members 5 and 6 and the bottom of the main body 1 can be appropriately adjusted according to the symptoms. After the side support plates 2 and 3 have been adjusted and fixed to the main body 1 once, it is not necessary to remove them when attaching or detaching the brace later.

It is desirable that the main body is formed into a shape corresponding to the curved surface of the side of the lower leg, but a slight difference in shape is due to the fact that a material having a cushioning property to fill the space between the main body and the side support plate is filled. Can be addressed. For example, a pad having an appropriate shape and size, a pad with a hook-and-loop fastener on both sides is prepared, and if necessary, inserted between the main body and the side support plate or the lower side support member to insert the hook-and-loop fastener. It can be engaged.

The range-of-movement limiting mechanism of the lower side column member with respect to the side column plate is not limited to the above-mentioned example, but is constituted by providing a stopper for preventing the lower side column member from rotating beyond a certain angle range. You can also.

It is well known that wrapping an elastic tape on each part of the foot based on the taping theory to protect muscles, ligaments and the like has been conventionally performed, and it is well known that there are some which have excellent effects. Winding the tape one by one requires considerable skill and time. In the present invention, this taping theory can be realized very easily by using a brace. That is, the main body constitutes an underlap portion, and is used for improving the protection and adhesion of the rigid side support plate, the hard front shell portion, and the lower side support member to the foot. The part constitutes an anchor part, and the sole belt constitutes a star-up part.

[0017]

According to the present invention, the main body is formed in a shape having an open rear, and the main body is wrapped around the lower leg to be fitted to the curved surface of an individual's foot without fail. Since only the side and front of the lower leg are covered with the side support plate made of material and the front shell part, the back is not covered,
While maintaining good support of the side strut plate, it does not give a feeling of oppression or discomfort to the human body, and the side strut plate of the lower leg and the lower side strut member are hingedly connected, so that On the other hand, since the orthosis is in close contact and the movable range is restricted by the movable range limiting mechanism, the ankle joint is prevented from being bent without limitation, and the supportability is enhanced. Further, since all parts constituting the brace of the present invention can be separated,
When it becomes dirty, it is not necessary to wash the whole as it is, it is sufficient to remove only the part that needs to be washed and wash it, the treatment after use is very simple, each part was damaged or inappropriate In that case, only that part can be exchanged for a new one.
