（本発明の第１の実施形態）
図１乃至図４において、足関節サポーター１０は、靴下編機（例えば、株式会社村田製作所製の編み機種「ラムダアンフィニー（針数：１４４本、シリンダー径：３１／２インチ、１インチ間の針の本数：３６ゲージ）」）により丸編で編み立てられる筒状編地からなり、着用者２０の体表に密着して着用者２０の足関節を補助するサポーターである。 (First embodiment of the present invention)
1 to 4, the ankle joint supporter 10 is a sock knitting machine (for example, a knitting model “Lambda Anfiney (144 needles, cylinder diameter: 3½ inch, 1 inch) manufactured by Murata Manufacturing Co., Ltd. This is a supporter that is in close contact with the body surface of the wearer 20 and assists the ankle joint of the wearer 20.

足関節サポーター１０は、表糸、裏糸及びゴム糸を編糸とし、平編、リブ編、タック編、浮き編又はパイル編などで編成されてなる伸縮性のある編地であるベース生地部１に対して、異なる編み立てを施すことで、テーピング機能などの所望の機能性を具備する。なお、本実施形態に係るベース生地部１は、１×１の鹿の子編により編成してなる編地（以下、鹿の子編地と称す）である。 The ankle joint supporter 10 is a base fabric portion that is a stretchable knitted fabric that is knitted with a plain knitting, a rib knitting, a tuck knitting, a floating knitting, a pile knitting, etc. By applying different knitting to 1, desired functionality such as a taping function is provided. The base fabric portion 1 according to the present embodiment is a knitted fabric (hereinafter referred to as a “Kanoko knitted fabric”) knitted by a 1 × 1 Kanoko knitting.

ここで、鹿の子編地とは、コース方向及びウェール方向に、平編とタック（あるコースで編み目を脱出させずに、その後のコースで複数ループを脱出させる組織）とが交互に、又は数コースごとに表れる編地である。このため、ベース生地部１には、平編とタックとを併用することで、編地の表面に隆起や透かし目を作ることができ、鹿の子のような網目柄が表れる。 Here, the Kanoko knitted fabric is a combination of flat knitting and tack (a structure that allows multiple loops to escape in a subsequent course without escaping the stitches in a certain course) or several courses in the course direction and the wale direction. Each knitted fabric appears. For this reason, in the base fabric part 1, by using both the flat knitting and the tack, the surface of the knitted fabric can be raised and watermarked, and a mesh pattern like a Kanoko appears.

第１のアンカー部２は、足関節サポーター１０の筒状編地の一端（上端１０ａ）を周回して編成され、着用者２０の踝２１近傍の脛骨２２及び腓骨２３に対応する部分を周回し、着用者２０の下腿に足関節サポーター１０を締着させる編地である。 The first anchor portion 2 is knitted around one end (upper end 10a) of the tubular knitted fabric of the ankle supporter 10, and circulates at portions corresponding to the tibia 22 and the rib 23 near the heel 21 of the wearer 20. This is a knitted fabric that fastens the ankle supporter 10 to the lower leg of the wearer 20.

また、第２のアンカー部３は、足関節サポーター１０の筒状編地の他端（下端１０ｂ）を周回して編成され、着用者２０の中足趾節関節２４近傍の中足骨２５（第１中足骨２５ａ、第２中足骨２５ｂ、第３中足骨２５ｃ、第４中足骨２５ｄ及び第５中足骨２５ｅ）に対応する部分を周回し、着用者２０の足甲及び足裏に足関節サポーター１０を締着させる
編地である。 The second anchor portion 3 is knitted around the other end (lower end 10 b) of the tubular knitted fabric of the ankle supporter 10, and the metatarsal bone 25 ( The first metatarsal bone 25a, the second metatarsal bone 25b, the third metatarsal bone 25c, the fourth metatarsal bone 25d, and the fifth metatarsal bone 25e). This is a knitted fabric in which the ankle joint supporter 10 is fastened to the sole.

この第１のアンカー部２及び第２のアンカー部３は、足関節サポーター１０の周方向Ｈにおける伸縮抵抗が、足関節サポーター１０の周方向Ｈにおけるベース生地部１の伸縮抵抗より大きく編成されている。すなわち、素材に伸長を与えない状態から一定の伸長を与えた場合の張力をＦとして、足関節サポーター１０の周方向Ｈにおけるベース生地部１の張力をＦ_H1とし、足関節サポーター１０の周方向Ｈにおける第１のアンカー部２の張力をＦ_H2とし、足関節サポーター１０の周方向Ｈにおける第２のアンカー部３の張力をＦ_H3とした場合に、第１のアンカー部２及び第２のアンカー部３がベース生地部１と比較して、足関節サポーター１０の周方向Ｈに強い締付力を持つような、Ｆ_H2＝Ｆ_H3＞Ｆ_H1という大小関係を有する。 The first anchor part 2 and the second anchor part 3 are knitted so that the stretch resistance in the circumferential direction H of the ankle supporter 10 is larger than the stretch resistance of the base fabric part 1 in the circumferential direction H of the ankle supporter 10. Yes. That is, the tension in the case where the material is not stretched is given a tensile force F, the tension of the base fabric portion 1 in the circumferential direction H of the ankle supporter 10 is _FH1, and the circumferential direction of the ankle supporter 10 When the tension of the first anchor part 2 at _H is F _H2 and the tension of the second anchor part 3 in the circumferential direction H of the ankle supporter 10 is F _H3 , the first anchor part 2 and the second anchor part 2 Compared with the base fabric portion 1, the anchor portion 3 has a magnitude relationship of F _H2 = F _H3 > F _H1 so that it has a strong tightening force in the circumferential direction H of the ankle supporter 10.

具体的な編地として、第１のアンカー部２は、１×１の鹿の子編とタック編とを併用した編地（以下、鹿の子編・タック編地と称す）を、足関節サポーター１０の上端１０ａで足関節サポーター１０の内側に折り返して身部１２（靴下の身部に相当）との境界で他の糸（例えば、ウーリーナイロン糸）で縫製した二重の鹿の子編・タック編地（以下、二重鹿の子編・タック編地と称す）にすることにより、ベース生地部１に対して、足関節サポーター１０の周方向Ｈにおける伸縮抵抗を大きくすることができる。また、第２のアンカー部３は、足関節サポーター１０の下端１０ｂで足関節サポーター１０の内側に鹿の子編・タック編地を折り返して足部１１（靴下の爪先を除く足部に相当）との境界で他の糸（例えば、ウーリーナイロン糸）で縫製した二重の鹿の子編・タック編地（二重鹿の子編・タック編地）にすることにより、ベース生地部１に対して、足関節サポーター１０の周方向Ｈにおける伸縮抵抗を大きくすることができる。
ここで、タック編地とは、生地を編成するときに、一時ある編み目を作らないで、次のコースを編むときに一緒に編み目を作る編地である。 As a specific knitted fabric, the first anchor portion 2 is a knitted fabric using both a 1 × 1 Kanoko knitting and a tack knitted fabric (hereinafter referred to as a Kanoko knitted / tuck knitted fabric), and the upper end of the ankle supporter 10. 10a, folded inside the ankle support 10 and sewn with another thread (for example, wooly nylon thread) at the boundary with the body 12 (corresponding to the body of the sock) , The resistance to expansion and contraction in the circumferential direction H of the ankle joint supporter 10 can be increased with respect to the base fabric portion 1. Further, the second anchor portion 3 is connected to the foot portion 11 (corresponding to the foot portion excluding the toe of the sock) by folding back the stag stitch / tuck knitted fabric inside the ankle joint supporter 10 at the lower end 10b of the ankle joint supporter 10. An ankle joint supporter for the base fabric part 1 by using a double sword knitting / tuck knitted fabric (double sword knitting / tuck knitted fabric) sewn with another thread (for example, wooly nylon thread) at the boundary. Ten expansion / contraction resistance in the circumferential direction H can be increased.
Here, the tucked knitted fabric is a knitted fabric that does not make a temporary stitch when knitting a fabric but creates a stitch together when the next course is knitted.

このように、第１のアンカー部２は、着用者２０の下腿を周回して編成され、足関節サポーター１０の周方向Ｈにおける伸縮抵抗が、足関節サポーター１０の周方向Ｈにおけるベース生地部１の伸縮抵抗より大きいことにより、着用者２０の下腿に足関節サポーター１０を固定し、足関節の背屈時における足関節サポーター１０の上端１０ａのずり下がりを抑制することができる。また、第１のアンカー部２は、後述する第１の支持部４が連結され、この第１の支持部４のアンカーとしても機能する。 Thus, the first anchor part 2 is knitted around the lower leg of the wearer 20, and the stretch resistance in the circumferential direction H of the ankle supporter 10 is the base fabric part 1 in the circumferential direction H of the ankle supporter 10. Since the ankle supporter 10 is fixed to the lower leg of the wearer 20, the upper end 10 a of the ankle supporter 10 can be prevented from sliding down when the ankle joint is dorsiflexed. Further, the first anchor portion 2 is connected to a first support portion 4 to be described later, and also functions as an anchor of the first support portion 4.

また、第２のアンカー部３は、着用者２０の足甲及び足裏を周回して編成され、足関節サポーター１０の周方向Ｈにおける伸縮抵抗が、足関節サポーター１０の周方向Ｈにおけるベース生地部１の伸縮抵抗より大きいことにより、着用者２０の足甲及び足裏に足関節サポーター１０を固定し、足関節の背屈時における足関節サポーター１０の下端１０ｂのずり上がりを抑制することができる。 The second anchor portion 3 is knitted around the instep and sole of the wearer 20, and the stretch resistance in the circumferential direction H of the ankle supporter 10 is the base fabric in the circumferential direction H of the ankle supporter 10. By being larger than the expansion / contraction resistance of the part 1, the ankle supporter 10 is fixed to the instep and sole of the wearer 20, and the lower end 10b of the ankle supporter 10 is restrained from rising when the ankle joint is bent back. it can.

特に、第１のアンカー部２及び第２のアンカー部３は、後述する第１の支持部４及び第２の支持部５の位置ずれを抑制し、第１の支持部４及び第２の支持部５による所望のテーピング機能を発揮させ、テーピング機能の安定性を図ることができる。 In particular, the first anchor part 2 and the second anchor part 3 suppress the displacement of the first support part 4 and the second support part 5 described later, and the first support part 4 and the second support part 5. The desired taping function by the part 5 can be exhibited and the stability of the taping function can be achieved.

なお、第１のアンカー部２及び第２のアンカー部３による着用者２０の下腿並びに足甲及び足裏に対する締付力を強くしすぎると、下腿並びに足甲及び足裏における血流阻害を生じさせ、着用者２０に不快感を起こさせる。特に、この不快感は、足甲及び足裏に比べ、下腿において顕著である。 If the tightening force on the lower leg, the instep and the sole of the wearer 20 by the first anchor part 2 and the second anchor part 3 is too strong, blood flow in the lower leg, the instep and the sole is inhibited. Causing the wearer 20 to feel uncomfortable. In particular, this discomfort is more prominent in the lower leg than in the instep and sole.

このため、本実施形態に係る足関節サポーター１０は、第１のアンカー部２及び第２のアンカー部３の度目を調整（例えば、第２のアンカー部３に対して第１のアンカー部２の
締付力を１０％程度小さく）することで、着用者２０に与える不快感を緩和している。すなわち、本実施形態に係る足関節サポーター１０は、足関節サポーター１０の周方向Ｈに適度な締付力を持つように、Ｆ_H3＞Ｆ_H2＞Ｆ_H1という大小関係を有することが好ましい。 For this reason, the ankle supporter 10 according to the present embodiment adjusts the degree of the first anchor part 2 and the second anchor part 3 (for example, the first anchor part 2 with respect to the second anchor part 3). By reducing the tightening force by about 10%, the discomfort given to the wearer 20 is alleviated. That is, the ankle supporter 10 according to the present embodiment preferably has a magnitude relationship of F _H3 > F _H2 > F _H1 so as to have an appropriate tightening force in the circumferential direction H of the ankle supporter 10.

踵部６は、着用者２０の踵に対応するかかと成形部分であり、平編により編成してなる編地（以下、平編地と称す）である。 The heel part 6 is a heel molded part corresponding to the heel of the wearer 20, and is a knitted fabric (hereinafter referred to as a flat knitted fabric) knitted by a flat knitting.

第１の支持部４は、第１のアンカー部２に連結して、着用者２０の脛骨２２及び腓骨２３の外側面に対応する部分から、内踝２１ａ及び外踝２１ｂに対応する部分をそれぞれ通り、着用者２０の足裏に対応する部分で一連となる編地である。 The first support portion 4 is connected to the first anchor portion 2 and passes from the portions corresponding to the outer surfaces of the tibia 22 and the ribs 23 of the wearer 20 through the portions corresponding to the inner collar 21a and the outer collar 21b, respectively. The knitted fabric is a series of parts corresponding to the soles of the wearer 20.

この第１の支持部４は、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗が、足関節サポーター１０の周方向Ｈにおける伸縮抵抗より大きく編成されている。すなわち、足関節サポーター１０の長さ方向Ｌにおける第１の支持部４の張力をＦ_L4とし、足関節サポーター１０の周方向Ｈにおける第１の支持部４の張力をＦ_H4とした場合に、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L4＞Ｆ_H4という大小関係を有する。 The first support portion 4 is knitted such that the stretch resistance in the length direction L of the ankle supporter 10 is larger than the stretch resistance in the circumferential direction H of the ankle supporter 10. In other words, the first tension of the support portion 4 in the length direction L of the foot joint supporter 10 and F _L4, the first tension of the support portion 4 in the circumferential direction H of the ankle supporter 10 when the F _H4, It has a magnitude relationship of F _L4 > F _H4 that has a strong tightening force in the length direction L of the ankle joint supporter 10.

また、第１の支持部４は、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗が、足関節サポーター１０の長さ方向Ｌにおけるベース生地部１の伸縮抵抗より大きく編成されている。すなわち、足関節サポーター１０の長さ方向Ｌにおけるベース生地部１の張力をＦ_L1とした場合に、第１の支持部４がベース生地部１と比較して、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L4＞Ｆ_L1という大小関係を有する。 Further, the first support portion 4 is knitted so that the stretch resistance in the length direction L of the ankle support 10 is larger than the stretch resistance of the base fabric portion 1 in the length direction L of the ankle support 10. That is, when the tension of the base fabric portion 1 in the length direction L of the ankle joint supporter 10 is F _L1 , the first support portion 4 is longer than the base fabric portion 1 in the length direction of the ankle joint supporter 10. It has a magnitude relationship of F _L4 > F _L1 so that L has a strong tightening force.

具体的には、第１の支持部４を、４×２のタック編により編成してなる編地（以下、４タック編地と称す）としている。 Specifically, the first support portion 4 is a knitted fabric knitted by 4 × 2 tack knitting (hereinafter referred to as “4 tack knitted fabric”).

このように、第１の支持部４を４タック編地とすることにより、コース方向の伸びを無くし、鹿の子編地のベース生地部１に対して、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗を大きくすることができる。このため、第１の支持部４は、第１のアンカー部２から足裏まで延在して着用者２０の内踝２１ａ及び外踝２１ｂを両側面から支持し、足首の左右の振れを抑制して、着用者２０の歩行を補助し、足関節の内反捻挫及び外反捻挫を予防することができると共に、足関節の背屈を制限することなく、重い荷物を持っての作業時に着用者２０の動作を補助することができる。 Thus, by making the 1st support part 4 into a 4-tuck knitted fabric, the extension of a course direction is eliminated and it is expansion-contraction in the length direction L of the ankle supporter 10 with respect to the base fabric part 1 of a Kanoko knitted fabric. The resistance can be increased. For this reason, the 1st support part 4 is extended from the 1st anchor part 2 to the sole, and supports the inner heel 21a and the outer heel 21b of the wearer 20 from both sides, and suppresses the right and left deflection of the ankle. In addition to assisting the wearer 20 in walking, it is possible to prevent varus and valgus sprains of the ankle joint, and at the time of work with heavy luggage without restricting the dorsiflexion of the ankle joint. Can assist in the operation.

第２の支持部５は、第１のアンカー部２の背面側における第１のアンカー部２及び踵部６間から左右の第１の支持部４にそれぞれ延在して連結する編地である。 The second support portion 5 is a knitted fabric that extends from the first anchor portion 2 and the heel portion 6 on the back side of the first anchor portion 2 to the left and right first support portions 4 and connects them. .

この第２の支持部５は、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗が、足関節サポーター１０の周方向Ｈにおける伸縮抵抗より大きく編成されている。すなわち、足関節サポーター１０の長さ方向Ｌにおける第２の支持部５の張力をＦ_L5とし、足関節サポーター１０の周方向Ｈにおける第２の支持部５の張力をＦ_H5とした場合に、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L5＞Ｆ_H5という大小関係を有する。 The second support portion 5 is knitted so that the stretch resistance in the length direction L of the ankle supporter 10 is larger than the stretch resistance in the circumferential direction H of the ankle supporter 10. That is, the tension of the second supporting portion 5 in the length direction L of the foot joint supporter 10 and F _L5, the tension of the second supporting portion 5 in the circumferential direction H of the ankle supporter 10 when the F _H5, It has a magnitude relationship of F _L5 > F _H5 so as to have a strong tightening force in the length direction L of the ankle joint supporter 10.

また、第２の支持部５は、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗が、足関節サポーター１０の長さ方向Ｌにおけるベース生地部１の伸縮抵抗より大きく編成されている。すなわち、第２の支持部５がベース生地部１と比較して、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L5＞Ｆ_L1という大小関係を有する。 Further, the second support portion 5 is knitted so that the stretch resistance in the length direction L of the ankle supporter 10 is larger than the stretch resistance of the base fabric portion 1 in the length direction L of the ankle supporter 10. That is, the second support portion 5 has a magnitude relationship of F _L5 > F _L1 such that the second support portion 5 has a stronger tightening force in the length direction L of the ankle supporter 10 than the base fabric portion 1.

具体的には、第２の支持部５を、１×１のタック編により編成してなる編地（以下、１タック編地と称す）としている。 Specifically, the second support portion 5 is a knitted fabric knitted by 1 × 1 tack knitting (hereinafter referred to as “1 tack knitted fabric”).

このように、第２の支持部５を１タック編地とすることにより、コース方向の伸びを無くし、鹿の子編地のベース生地部１に対して、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗を大きくすることができる。このため、第２の支持部５は、第１の支持部４に連結して第１の支持部４と一体となり、着用者２０の内踝２１ａ及び外踝２１ｂを両側面から支持し、足首の左右の振れを抑制すると共に、着用者２０の足裏（後述する土踏まず部８）まで延在する第１の支持部４を介して土踏まず部８を引き上げ、着用者２０の歩行を補助して疲労を軽減することができる。 Thus, by making the 2nd support part 5 into 1 tuck knitted fabric, the expansion | extension of the course direction is eliminated, and the expansion-contraction in the length direction L of the ankle joint supporter 10 is made with respect to the base fabric part 1 of the Kanoko knitted fabric. The resistance can be increased. For this reason, the 2nd support part 5 is connected with the 1st support part 4, is integrated with the 1st support part 4, supports the inner collar 21a and the outer collar 21b of the wearer 20 from both sides, and the right and left of the ankle The arch portion 8 is pulled up via the first support portion 4 extending to the sole of the wearer 20 (the arch portion 8 described later) to assist the wearer 20 in walking and fatigue. Can be reduced.

なお、第２の支持部５は、比較的硬質の１タック編地であるため、踵部６に隣接する編地をベース生地部１とし、着用者２０のアキレス腱に対応する部分を伸縮性のあるベース生地部１とすることで、着用者２０のアキレス腱の動きを阻害することがない。 Since the second support portion 5 is a relatively hard one-tuck knitted fabric, the knitted fabric adjacent to the heel portion 6 is used as the base fabric portion 1, and the portion corresponding to the Achilles tendon of the wearer 20 is stretchable. By using a certain base fabric portion 1, the movement of the Achilles tendon of the wearer 20 is not hindered.

足関節サポーター１０の正面側における足部１１と身部１２との境界近傍で、足関節サポーター１０の周方向Ｈに延在する領域であり、足関節サポーター１０の屈曲部分（着用者２０の足首の正面側）におけるしわを逃し、足関節の背屈の動きを阻害しないように、ベース生地部１における編地の厚みに対して、厚みを薄くした編地である。 This is an area extending in the circumferential direction H of the ankle supporter 10 in the vicinity of the boundary between the foot 11 and the body 12 on the front side of the ankle supporter 10, and a bent portion of the ankle supporter 10 (the ankle of the wearer 20 The knitted fabric is made thinner than the thickness of the knitted fabric in the base fabric portion 1 so that wrinkles on the front side of the base fabric portion 1 are not missed and the dorsiflexion movement of the ankle joint is not hindered.

なお、図１乃至図４においては、３つの薄編部７を長さ方向Ｌに並設した場合を示しているが、足関節サポーター１０の屈曲部分におけるしわの発生防止や足関節の背屈を制限しないようにできるのであれば、この数に限られるものではない。 1 to 4 show the case where the three thin knitted portions 7 are arranged in the length direction L, but it is possible to prevent wrinkles from occurring at the bent portion of the ankle supporter 10 and to dorsiflexion of the ankle joint. However, the number is not limited to this number as long as it is possible not to limit the above.

また、本実施形態に係る薄編部７は、通気性のよい編組織である２×１のメッシュ編で編成された編地（以下、メッシュ編地と称す）にすることにより、鹿の子編地のベース生地部１に対して、足関節サポーター１０の長さ方向Ｌにおける伸縮抵抗を小さくすることができる。このメッシュ編地とは、生地を編成するときに、一時ある編み目を作らないで、次のコースを編むときに一緒に編み目を作り、メッシュ形態の編みでよく伸びる編地である。 Further, the thin knitted portion 7 according to the present embodiment is a knitted fabric knitted with a 2 × 1 mesh knitted fabric (hereinafter referred to as a mesh knitted fabric) that is a knitted structure with good air permeability. The expansion and contraction resistance in the length direction L of the ankle joint supporter 10 can be reduced with respect to the base fabric portion 1. This mesh knitted fabric is a knitted fabric that does not make a temporary stitch when knitting a fabric, but creates a stitch together when the next course is knitted, and stretches well by knitting in a mesh form.

特に、薄編部７は、足関節サポーター１０の長さ方向Ｌにおける薄編部７の張力をＦ_L7とした場合に、薄編部７がベース生地部１と比較して、足関節サポーター１０の長さ方向Ｌに弱い締付力を持つような、Ｆ_L1＞Ｆ_L7という大小関係を有する。 In particular, the thin knitted section 7, the tension of the thin knitted portion 7 in the longitudinal direction L of the foot joint supporter 10 when the F _L7, thin knitted part 7 compared to the base fabric portion 1, ankle supporter 10 In the longitudinal direction L, there is a magnitude relationship of F _L1 > F _L7 that has a weak tightening force.

土踏まず部８は、着用者２０の足の土踏まずに対応する部分であり、具体的には、３×１のゴム編（リブ編）と添え糸編とを併用した編地（以下、ゴム編・添え糸編地と称す）としている。 The arch portion 8 is a portion corresponding to the arch of the foot of the wearer 20, and specifically, a knitted fabric (hereinafter referred to as a rubber knitted fabric / ribbed fabric) using a 3 × 1 rubber knitting (rib knitting) and a splicing knitting together. It is called a spliced yarn knitted fabric).

ここで、ゴム編地とは、たて方向に表目のウェールと裏目のウェールとが交互に並ぶ編み目で、本実施形態においては、３ウェール毎に表目と裏目とを配列した３×１の編地である。 Here, the rubber knitted fabric is a stitch in which front wales and back wales are alternately arranged in the vertical direction, and in this embodiment, the front and back knives are arranged every 3 wales. Is a knitted fabric.

また、ゴム編・添え糸編地では、ゴム編の地編糸である表糸を飛ばして（表糸の替わりに）他の編糸（例えば、ウーリーナイロン糸）を添えて給糸することで、足関節サポーター１０の長さ方向Ｌにおける土踏まず部８の伸縮を適度に抑えている。すなわち、ゴム編・添え糸編地では、足関節サポーター１０の長さ方向Ｌの伸縮抵抗が周方向Ｈの伸縮抵抗と比較して大きく編成されている。また、足関節サポーター１０の長さ方向Ｌにおける土踏まず部８の伸縮抵抗は、足関節サポーター１０の長さ方向Ｌにおけるベース生地部１の伸縮抵抗より大きく編成されている。また、ゴム編・添え糸編地では、土踏まず部８と他の領域（第１の支持部４）との境界において他の編糸をカットしている（カットボス）。 Also, in rubber knitting and splicing yarn knitted fabrics, the surface yarn that is the base knitting yarn of rubber knitting is skipped (instead of the front yarn) and other knitting yarn (for example, wooly nylon yarn) is added and fed. The expansion and contraction of the arch portion 8 in the length direction L of the ankle joint supporter 10 is moderately suppressed. That is, in the rubber knitted and spliced yarn knitted fabric, the stretch resistance in the length direction L of the ankle supporter 10 is knitted larger than the stretch resistance in the circumferential direction H. In addition, the stretch resistance of the arch portion 8 in the length direction L of the ankle supporter 10 is knitted to be greater than the stretch resistance of the base fabric portion 1 in the length direction L of the ankle supporter 10. Further, in the rubber knitting and spliced yarn knitted fabric, other knitting yarn is cut (cut boss) at the boundary between the arch portion 8 and another region (first support portion 4).

特に、土踏まず部８は、足関節サポーター１０の長さ方向Ｌにおける土踏まず部８の張力をＦ_L8とし、足関節サポーター１０の周方向Ｈにおける土踏まず部８の張力をＦ_H8とした場合に、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L8＞Ｆ_H8という大小関係を有する。また、土踏まず部８は、ベース生地部１と比較して、足関節サポーター１０の長さ方向Ｌに強い締付力を持つような、Ｆ_L8＞Ｆ_L1という大小関係を有する。 In particular, the arch portion 8 is a foot when the tension of the arch portion 8 in the length direction L of the ankle supporter 10 is F _L8 and the tension of the arch portion 8 in the circumferential direction H of the ankle supporter 10 is F _H8. The joint supporter 10 has a magnitude relationship of F _L8 > F _H8 so as to have a strong tightening force in the length direction L. Further, the arch portion 8 has a magnitude relationship of F _L8 > F _L1 that has a strong tightening force in the length direction L of the ankle supporter 10 as compared with the base fabric portion 1.

この土踏まず部８は、着用者２０の土踏まずを横切るアーチの形成をサポートし、足底のクッション性を高め、重い荷物などを運ぶときに受ける荷重を分散させるスプリングとしての役割を果し、着用者２０の足に掛かる衝撃から保護することができる。 The arch portion 8 supports the formation of an arch that crosses the arch of the wearer 20, improves the cushioning of the sole, and acts as a spring that distributes the load received when carrying heavy loads, etc. It can protect from the impact on 20 legs.

なお、本実施形態に係る足関節サポーター１０は、前述した各部位の編地により、足関節サポーター１０の長さ方向Ｌにおける土踏まず部８の伸縮抵抗が、足関節サポーター１０の長さ方向Ｌにおける第１の支持部４の伸縮抵抗より小さい。また、足関節サポーター１０の長さ方向Ｌにおける踵部６は、足関節サポーター１０の長さ方向Ｌにおけるベース生地部１の伸縮抵抗とほぼ等しい。 In addition, the ankle joint supporter 10 according to the present embodiment has an elastic resistance of the arch portion 8 in the length direction L of the ankle supporter 10 in the length direction L of the ankle supporter 10 due to the knitted fabric of each part described above. It is smaller than the expansion and contraction resistance of the first support portion 4. Further, the heel part 6 in the length direction L of the ankle supporter 10 is substantially equal to the expansion and contraction resistance of the base fabric part 1 in the length direction L of the ankle supporter 10.

したがって、本実施形態に係る足関節サポーター１０は、足関節サポーター１０の長さ方向Ｌにおける張力Ｆにおいて、次式（１）に示す大小関係を満たすものである。ただし、次式（１）において、Ｆ_L6は足関節サポーター１０の長さ方向Ｌにおける踵部６の張力である。 Therefore, the ankle supporter 10 according to the present embodiment satisfies the magnitude relationship represented by the following expression (1) in the tension F in the length direction L of the ankle supporter 10. However, in the following formula (1), F _L6 is the tension of the buttocks 6 in the length direction L of the ankle supporter 10.

また、足関節サポーター１０の周方向Ｈにおける第２の支持部５の伸縮抵抗は、足関節サポーター１０の周方向Ｈにおける第２のアンカー部３の伸縮抵抗とほぼ等しい。また、足関節サポーター１０の周方向Ｈにおける踵部６の伸縮抵抗は、足関節サポーター１０の周方向Ｈにおけるベース生地部１の伸縮抵抗とほぼ等しい。 [Equation 1]
F _L4 > F _L8 > F _L1 ≒ F _L6 > F _L7 (1)
Further, the expansion / contraction resistance of the second support portion 5 in the circumferential direction H of the ankle joint supporter 10 is substantially equal to the expansion / contraction resistance of the second anchor portion 3 in the circumferential direction H of the ankle supporter 10. Further, the expansion / contraction resistance of the heel part 6 in the circumferential direction H of the ankle supporter 10 is substantially equal to the expansion / contraction resistance of the base fabric part 1 in the circumferential direction H of the ankle supporter 10.

したがって、本実施形態に係る足関節サポーター１０は、足関節サポーター１０の周方向Ｈにおける張力Ｆにおいて、次式（２）に示す大小関係を満たすものである。ただし、次式（２）において、Ｆ_H5は足関節サポーター１０の周方向Ｈにおける第２の支持部５の張力であり、Ｆ_H6は足関節サポーター１０の周方向Ｈにおける踵部６の張力である。 Therefore, the ankle supporter 10 according to the present embodiment satisfies the magnitude relationship represented by the following expression (2) in the tension F in the circumferential direction H of the ankle supporter 10. However, in the following equation (2), F _H5 is the tension of the second support part 5 in the circumferential direction H of the ankle supporter 10, and F _H6 is the tension of the heel part 6 in the circumferential direction H of the ankle supporter 10. is there.
