　足のトラブルは男性の５０％、女性の７５％が抱えていると言われている。足のトラブルである外反母趾、扁平足、たこ、巻き爪、足底腱膜炎などは「足の骨格の歪み」が主な原因の１つである。「足の骨格の歪み」は、足の痛み、疲れやすさ、むくみなどの症状を引き起こす原因になる。また、「足の骨格の歪み」を放置すると、ひざや腰の痛みを誘発する場合がある。足やひざ、腰の痛みなど筋骨格系疾患は、高齢者の健康寿命を短くしている要因の１つである。 It is said that 50% of men and 75% of women have foot problems. One of the main causes of foot problems such as hallux valgus, flat feet, octopus, ingrown nails, and plantar fasciitis is "distortion of the skeleton of the foot". "Distortion of the skeleton of the foot" causes symptoms such as pain in the foot, tiredness, and swelling. In addition, if "distortion of the skeleton of the foot" is left untreated, it may induce pain in the knees and lower back. Musculoskeletal disorders such as pain in the legs, knees, and lower back are one of the factors that shorten the healthy life expectancy of the elderly.
　靴などの履物の中にインソールを入れて足の骨格の歪みを矯正することがこれらの筋骨格系疾患に有効な処置方法であるとして知られている。ただし、市販されているような柔らかいインソールでは、体重を支えきることができず足の骨格の歪みを矯正する力が乏しい。また、市販されているインソールの場合、そのインソールを患者一人ひとりの足の骨格に適合させることは困難である。 It is known that putting an insole in footwear such as shoes to correct the distortion of the skeleton of the foot is an effective treatment method for these musculoskeletal disorders. However, soft insoles such as those on the market cannot support the weight and have little ability to correct the distortion of the skeleton of the foot. Moreover, in the case of commercially available insoles, it is difficult to adapt the insoles to the skeleton of each patient's foot.
　足の骨格の歪みを矯正するには、「硬い」インソールが必要になる。しかし硬いインソールを用いるには、ユーザ一人ひとりの足の骨格に適合するものでなければ、その使用に際し不具合が発生することがある。 A "hard" insole is required to correct the distortion of the skeleton of the foot. However, in order to use a hard insole, if it does not fit the skeleton of each user's foot, problems may occur when using it.
　硬いインソールを処方する医療機関はあるがその数は少ない。また、そのような医療機関であっても採寸や製造を手作業で行っているため、待ち時間が長い、若しくは費用が高いといった課題があり、手軽にオーダーメイドのインソールを手に入れることが難しい。 There are medical institutions that prescribe hard insoles, but the number is small. In addition, even in such medical institutions, since measuring and manufacturing are performed manually, there are problems such as long waiting time or high cost, and it is difficult to easily obtain a custom-made insole. ..
　そこで特許文献１に記載の開示が考案された。特許文献１に記載の開示は、この開示にかかるシステムを医療施設、スポーツ施設、シューズショップ等に設置することで、多くの被験者が自ら自分の足に適合するインソールを選定することができるとしている。 Therefore, the disclosure described in Patent Document 1 was devised. The disclosure described in Patent Document 1 states that by installing the system related to this disclosure in medical facilities, sports facilities, shoe shops, etc., many subjects can select insoles that fit their feet by themselves. ..

　以下に本開示に係る履物のインソール１（以下、単にインソール１という。）の実施の形態について、図１乃至図４を参照して説明する。なお、本開示は以下に詳述する本開示の実施形態に限定されることなく、種々変形して実施することができる。 Hereinafter, embodiments of the footwear insole 1 (hereinafter, simply referred to as insole 1) according to the present disclosure will be described with reference to FIGS. 1 to 4. The present disclosure is not limited to the embodiments of the present disclosure described in detail below, and can be implemented in various modifications.
　図１乃至図４を参照して、インソール１の構成について説明する。図１に１対のインソール１の外観を示す。１対のインソール１は、左足用の履物の内部に挿入される左足用インソール１ａと右足の履物の内部に挿入される右足用インソール１ｂとの両方を備える。 The configuration of the insole 1 will be described with reference to FIGS. 1 to 4. FIG. 1 shows the appearance of a pair of insoles 1. The pair of insoles 1 includes both a left foot insole 1a inserted inside the left foot footwear and a right foot insole 1b inserted inside the right foot footwear.
　インソール１を使用する際は左右どちらか一方のインソール１ａ又は１ｂを単独で用いても良いし、左右１対のインソール１を同時に用いても良い。以下、全ての図面に示されているインソールは右足用インソール１ｂであり、左足用インソール１ａは右足用インソール１ｂと鏡像関係にあるのでその説明を省略する。 When using the insole 1, either the left or right insole 1a or 1b may be used alone, or a pair of left and right insoles 1 may be used at the same time. Hereinafter, the insoles shown in all the drawings are the insoles 1b for the right foot, and the insoles 1a for the left foot have a mirror image relationship with the insoles 1b for the right foot, and thus the description thereof will be omitted.
　インソール１ｂは、三層構造になっており、下層から上層に向かって順に支持部材２、クッション部材３、カバー部４が一体的に接合されている。クッション部材３およびカバー部４は、足の裏全体に密着するように形成されている。支持部材２は足の後端から足指の付け根までの範囲を覆うように形成され、クッション部材３の裏面に合着されている。接合には合成ゴム系、ニトリルゴム系、クロロプレンゴム系などの接着剤による接着、若しくは熱溶着による接着が用いられる。この接合の方法は、支持部材２、クッション部材３、及びカバー部３が一体的に合着する方法であればよく、上記した方法以外の方法であってもよい。 The insole 1b has a three-layer structure, and the support member 2, the cushion member 3, and the cover portion 4 are integrally joined in this order from the lower layer to the upper layer. The cushion member 3 and the cover portion 4 are formed so as to be in close contact with the entire sole of the foot. The support member 2 is formed so as to cover the range from the rear end of the foot to the base of the toes, and is attached to the back surface of the cushion member 3. Adhesives such as synthetic rubber, nitrile rubber, and chloroprene rubber, or heat welding are used for bonding. The joining method may be any method as long as the support member 2, the cushion member 3, and the cover portion 3 are integrally joined, and may be a method other than the above-mentioned method.
　支持部材２は厚さ２．５～３ｍｍほどの板状のもので、硬質であるとともに弾性的に可撓可能である。支持部材２は、３Dプリンタにより成形されるため、３Ｄプリンタ用の材料であるナイロン樹脂（別名、ポリアミド樹脂）などが用いられる。ナイロン樹脂は、比較的安価で、強度があり、更に熱に強く耐熱温度は約１００℃であり、造形時間が短いので、３Dプリンタの成形用の素材として広く用いられている。 The support member 2 has a plate-like shape with a thickness of about 2.5 to 3 mm, and is rigid and elastically flexible. Since the support member 2 is molded by a 3D printer, nylon resin (also known as polyamide resin), which is a material for a 3D printer, or the like is used. Nylon resin is relatively inexpensive, strong, heat resistant, has a heat resistant temperature of about 100 ° C., and has a short molding time, and is therefore widely used as a material for molding 3D printers.
　クッション部材３は厚さ３ｍｍ程度の板状のもので、靴底を介して伝達される地面からの衝撃を緩和するためにクッション性を備えている。クッション部材３の素材はウレタン樹脂などが用いられる。ウレタン樹脂は、ゴムのような伸縮性に優れ、湿度や温度の変化に高い耐性を有する。 The cushion member 3 is a plate-shaped material having a thickness of about 3 mm, and has cushioning properties to alleviate the impact from the ground transmitted through the sole. Urethane resin or the like is used as the material of the cushion member 3. Urethane resin has excellent elasticity like rubber and has high resistance to changes in humidity and temperature.
　カバー部４は厚さ１ｍｍ程度の板状のもので、クッション部材３の上面を覆うように合着されている。カバー部４の素材は和紙を含んだコットンなどが用いられ、吸湿性、消臭性に優れている。なお、クッション部材３の上面に吸湿性、消臭性の機能を持たせることで、カバー部４を別途設けることなくカバー部４と同等の機能をクッション部材３に備えることが可能になる。 The cover portion 4 is a plate-shaped one having a thickness of about 1 mm, and is joined so as to cover the upper surface of the cushion member 3. As the material of the cover portion 4, cotton or the like containing Japanese paper is used, and it is excellent in hygroscopicity and deodorant property. By providing the upper surface of the cushion member 3 with hygroscopic and deodorant functions, the cushion member 3 can be provided with the same function as the cover portion 4 without separately providing the cover portion 4.
　図２乃至図６を参照して支持部材２の構成及び機能についてより詳細に説明する。支持部材２は、足５の後端から足趾６の付け根までの範囲を足５の裏側から足５の骨格を支えるように配置される。足５の骨格は３つのアーチ（内側縦アーチ７、外側縦アーチ８、横アーチ９）を備える。支持部材２は足５の裏側からこの３つのアーチのアーチ形状を適切に保つことを役割として担っている。 The configuration and function of the support member 2 will be described in more detail with reference to FIGS. 2 to 6. The support member 2 is arranged so as to support the skeleton of the foot 5 from the back side of the foot 5 in the range from the rear end of the foot 5 to the base of the toe 6. The skeleton of the foot 5 includes three arches (inner longitudinal arch 7, lateral longitudinal arch 8, lateral arch 9). The support member 2 plays a role of properly maintaining the arch shape of these three arches from the back side of the foot 5.

　支持部材２における足５の土踏まずに対応する位置の高さは、内側縦アーチ７のアーチ形状を適切に維持するように設計される。内側縦アーチ７の頂点は舟状骨１２（図５参照）の付近にあり、支持部材２における舟状骨１２に対応する位置の高さを後述する足データに基づいて設計する。 The height of the position of the support member 2 corresponding to the arch of the foot 5 is designed to appropriately maintain the arch shape of the inner vertical arch 7. The apex of the medial longitudinal arch 7 is in the vicinity of the scaphoid 12 (see FIG. 5), and the height of the position of the support member 2 corresponding to the scaphoid 12 is designed based on the foot data described later.
　支持部材２における舟状骨１２に対応する位置の高さは、足５のウィンドラス機構を用いて設計する。図７を参照して足５のウィンドラス機構について説明する。図７（ａ）は足趾６を伸ばした状態を示し、図７（ｂ）は足趾６を背屈させた状態（ウィンドラス時）を示す。足５のウィンドラス機構とは、足趾６を上に挙げた（背屈した）際に、足底腱膜３０の巻き上げが起こり、内側縦アーチ７が緊張し足部剛性が高まり内側縦アーチ７の頂部に位置する舟状骨１２が上方に移動するしくみのことをいう。 The height of the position of the support member 2 corresponding to the scaphoid bone 12 is designed by using the windlass mechanism of the foot 5. The windlass mechanism of the foot 5 will be described with reference to FIG. 7. FIG. 7A shows a state in which the toe 6 is extended, and FIG. 7B shows a state in which the toe 6 is dorsiflexed (at the time of windlass). The windlass mechanism of the foot 5 is that when the toe 6 is raised (dorsiflexed), the plantar aponeurosis 30 is rolled up, the medial longitudinal arch 7 becomes tense, and the foot rigidity increases, and the medial longitudinal arch. It refers to a mechanism in which the scaphoid bone 12 located at the top of 7 moves upward.
　次に図８を参照して、支持部材２における足５の土踏まずに対応する位置の高さを設計する方法について説明する。支持部材２における足５の土踏まずに対応する位置の高さとは、内側縦アーチ７の頂点の付近の高さのことをいう。 Next, with reference to FIG. 8, a method of designing the height of the position corresponding to the arch of the foot 5 on the support member 2 will be described. The height of the position of the support member 2 corresponding to the arch of the foot 5 means the height near the apex of the inner vertical arch 7.
　図８に示すように、足趾６を伸ばした状態の種子骨３１から踵骨１０の後端までの距離の中点の位置における内側縦アーチ７の高さをａ１とし、足趾６を背屈した状態（ウィンドラス時）の種子骨３１から踵骨１０の後端までの距離の中点の位置における内側縦アーチ７の高さをａ２とする。そして、足５の土踏まずに対応する支持部材２の高さをｈとした場合、下記の式（１）の関係がある。 As shown in FIG. 8, the height of the medial longitudinal arch 7 at the midpoint of the distance from the sesamoid bone 31 with the toe 6 extended to the posterior end of the calcaneus 10 is a1, and the toe 6 is the back. Let a2 be the height of the medial longitudinal arch 7 at the midpoint of the distance from the sesamoid 31 in the bent state (at the time of windlass) to the posterior end of the calcaneus 10. Then, when the height of the support member 2 corresponding to the arch of the foot 5 is h, there is a relationship of the following equation (1).

　なお、Ａは定数であり０．５から０．８の値を取り得る。Ａは患者によって変わりうる値であり、実際の医療現場で患者一人ひとりに合わせて調整され決定される。例えば、後足部（踵付近）が外方に傾斜しやすい患者の場合はＡを大きくすると後足部（踵付近）が実際に外方に傾斜し易くなってしまうなどの問題があり、患者の足の特性に応じてＡを微調整する。また、患者一人ひとりのデータを収集し蓄積することで、新たな患者に対する最適な値を求めるための予測モデルを構築することが可能となる。 Note that A is a constant and can take a value of 0.5 to 0.8. A is a value that can change depending on the patient, and is adjusted and determined according to each patient in the actual medical field. For example, in the case of a patient whose hind foot (near the heel) tends to incline outward, there is a problem that if A is increased, the hind foot (near the heel) actually tends to incline outward, and the patient. Fine-tune A according to the characteristics of the foot. In addition, by collecting and accumulating data for each patient, it is possible to build a prediction model for obtaining the optimum value for a new patient.
　支持部材２の高さをウィンドラス時（足趾６を背屈した状態の時）の内側縦アーチ７の高さに合わせて支持部材２を作製すると、土踏まず本来の衝撃緩衝機能を阻害してしまう。反対に、支持部材２の高さを低く見積もると骨格矯正力が低下してしまう。本願の発明者らは、適度な衝撃緩衝機能を土踏まずから引き出し、患者が満足する性能を発揮できるか検証し、或いは患者の歩行を分析することで、上記の式（１）を導き出した。 When the support member 2 is manufactured by matching the height of the support member 2 with the height of the inner vertical arch 7 at the time of windlass (when the toe 6 is dorsiflexed), the arch does not interfere with the original shock absorbing function. It ends up. On the contrary, if the height of the support member 2 is underestimated, the skeletal correction force will decrease. The inventors of the present application have derived the above equation (1) by drawing out an appropriate shock absorbing function from the arch, verifying whether the patient can exhibit satisfactory performance, or analyzing the patient's gait.
　次に図９乃至図１２を参照して、支持部材２の長さと幅とを設計する方法について説明する。支持部材２の長さと幅とは、足５の踵底部２４、拇指球２５、及び小指球２６の３点の位置情報に基づいて決定される。そこで、先ずは後述する足データからこの３点の位置情報を取得する。 Next, a method of designing the length and width of the support member 2 will be described with reference to FIGS. 9 to 12. The length and width of the support member 2 are determined based on the position information of the heel bottom 24 of the foot 5, the thumb ball 25, and the hypothenar ball 26. Therefore, first, the position information of these three points is acquired from the foot data described later.
　図９に示す様に、拇指球２５の位置は第１基節骨１５の中心線と拇指球２５の最も腫れた部分からの水平線との交点とする。同じく図９に示す様に、小指球２６の位置は第５基節骨３２の中心線と小指球２６の最も腫れた部分の水平線との交点とする。 As shown in FIG. 9, the position of the ball 25 is the intersection of the center line of the first proximal phalanx 15 and the horizontal line from the most swollen part of the ball 25. Similarly, as shown in FIG. 9, the position of the hypothenar eminence 26 is the intersection of the center line of the fifth proximal phalanx 32 and the horizontal line of the most swollen part of the hypothenar eminence 26.
　踵底部２４の後端から拇指球２５の位置までの距離をｍ１とし、踵底部２４の後端から小指球２６の位置までの距離をｍ２と定義し、支持部材２の内側（拇指球２５側）の長さをｗ１、外側（小指球２６側）の長さをｗ２と定義した場合（図１１参照）、下記の式（２）、（３）の関係がある。なお、この明細書において、ｍ１及びｍ２を含みうる値としてｍを用い、ｗ１及びｗ２を含みうる値としてｗを用いることがある。 The distance from the rear end of the heel bottom 24 to the position of the ball 25 is defined as m1, and the distance from the rear end of the heel bottom 24 to the position of the hypothenar 26 is defined as m2. ) Is defined as w1 and the length on the outside (hypothenar eminence 26 side) is defined as w2 (see FIG. 11), and there is a relationship between the following equations (2) and (3). In this specification, m may be used as a value that can include m1 and m2, and w may be used as a value that can include w1 and w2.

Figure JPOXMLDOC01-appb-M000002
　支持部材２の内側（拇指球２５側）の長さｗ１と外側（小指球２６側）の長さｗ２とは異なる。なお、Ｂは定数であり０．０１から０．０３の値を取り得る。拇指球２５及び小指球２６の大きさは人それぞれであるので、実際の医療現場で患者一人ひとりに合わせてＢは調整され決定される。また、患者によっては外反母趾、強剛拇指などを有する場合があるので、このことも考慮してＢの値を微調整する必要がある。 The length w1 on the inside (thumb ball 25 side) and the length w2 on the outside (hypothenar ball 26 side) of the support member 2 are different. Note that B is a constant and can take a value of 0.01 to 0.03. Since the sizes of the thumb ball 25 and the hypothenar ball 26 are different for each person, B is adjusted and determined according to each patient in the actual medical field. In addition, some patients may have hallux valgus, strong thumb, etc., so it is necessary to fine-tune the value of B in consideration of this.
　拇指球２５の位置から小指球２６の位置までの距離をｍ３と定義し、支持部材２の幅寸法をｗ３と定義した場合（図１２参照）、下記の式（４）の関係がある。 When the distance from the position of the thumb ball 25 to the position of the hypothenar ball 26 is defined as m3 and the width dimension of the support member 2 is defined as w3 (see FIG. 12), there is a relationship of the following equation (4).
Figure JPOXMLDOC01-appb-M000003
Figure JPOXMLDOC01-appb-M000003
　なお、Ｃは定数であり０．０３から０．０７の値を取り得る。スポーツシューズなど幅の狭い靴に用いる場合、Ｃは０．０３に近い値となる。また、外反母趾が有る場合、足の幅は広くなるが、それに合わせて支持部材２の幅を決定するとインソール１自体が靴の側壁にぶつかる恐れがあり、実際の医療現場で患者が用いる靴に合わせてＣの値を微調整する必要がある。 Note that C is a constant and can take a value of 0.03 to 0.07. When used for narrow shoes such as sports shoes, C has a value close to 0.03. In addition, when there is a hallux valgus, the width of the foot becomes wider, but if the width of the support member 2 is determined accordingly, the insole 1 itself may hit the side wall of the shoe, and it matches the shoe used by the patient in the actual medical field. It is necessary to fine-tune the value of C.
　次に、図１３及び図１４を参照し、患者が使用する履物である靴３４がヒールの高い靴である場合の支持部材２の設計方法について説明する。図１３において、地面３７から靴３４内部の拇指球２５までの高さをｈ１とし、地面３７から靴３４内部の踵底部２４までの高さをｈ２とし、拇指球２５の中心から踵底部２４の中心までの距離をｅとした場合、靴３４を履いた状態における拇指球２５から踵底部２４までの傾斜角度γは下記の式（５）の関係がある。 Next, with reference to FIGS. 13 and 14, a method of designing the support member 2 when the shoe 34, which is the footwear used by the patient, is a shoe with a high heel will be described. In FIG. 13, the height from the ground 37 to the ball 25 inside the shoe 34 is h1, the height from the ground 37 to the bottom 24 of the heel 34 inside the shoe 34 is h2, and the height from the center of the ball 25 to the bottom 24 of the heel 24. When the distance to the center is e, the inclination angle γ from the thumb ball 25 to the heel bottom 24 when the shoe 34 is worn is related to the following equation (5).

Figure JPOXMLDOC01-appb-M000004
　次に、図１４におけるθについて説明する。θは、設計する支持部材２を側面視した場合において、支持部材２の踵部分の中心（ヒールカップに相当する部位の最低面部）３８と支持部材２の後端３９を結ぶ直線と、支持部材２の踵部分の中心（ヒールカップに相当する部位の最低面部）３８と支持部材２の後端部分の頂部４０とを結ぶ直線と、の間にできる角度である。 Next, θ in FIG. 14 will be described. θ is a straight line connecting the center of the heel portion of the support member 2 (the lowest surface portion of the portion corresponding to the heel cup) 38 and the rear end 39 of the support member 2 when the support member 2 to be designed is viewed from the side, and the support member. It is an angle formed between the center of the heel portion (the lowest surface portion of the portion corresponding to the heel cup) 38 and the straight line connecting the top portion 40 of the rear end portion of the support member 2.
　θがγに対して５度（deg）以上大きい場合は、θとγとの差が５度（deg）になるように支持部材２の後端部分の頂部４０の高さを低く設計する。このように設計を修正することで、ヒールの高い靴にインソール１を挿入した場合に、靴の踵部分においてインソール１が適度に密着する。その結果、靴のヒール部分とインソール１との間に隙間が生じることを防ぎ、靴の内部で足が靴の内壁にぶつかることを防ぐことができる。 When θ is 5 degrees (deg) or more larger than γ, the height of the top 40 of the rear end portion of the support member 2 is designed to be low so that the difference between θ and γ is 5 degrees (deg). By modifying the design in this way, when the insole 1 is inserted into a shoe having a high heel, the insole 1 is appropriately brought into close contact with the heel portion of the shoe. As a result, it is possible to prevent a gap from being formed between the heel portion of the shoe and the insole 1 and prevent the foot from hitting the inner wall of the shoe inside the shoe.
　次に、図１５乃至図１７を参照して、支持部材２、クッション部材３、及びカバー部４が一体的に接合されインソール１となった状態での成形方法について説明する。患者が使用する靴の大きさ、形状に合わせてインソール１を成形する。具体的には、インソール１が挿入された靴の中で靴の内壁と衝突し変形することがないように、また、インソール１が靴の内部で移動することがないように、インソール１の寸法を微調整する。インソール１の寸法の微調整はインソール１の機能を十分に発揮するために必要不可欠となる。 Next, with reference to FIGS. 15 to 17, a molding method in a state where the support member 2, the cushion member 3, and the cover portion 4 are integrally joined to form the insole 1 will be described. The insole 1 is molded according to the size and shape of the shoes used by the patient. Specifically, the dimensions of the insole 1 so that the insole 1 does not collide with the inner wall of the shoe and deform in the inserted shoe, and the insole 1 does not move inside the shoe. Fine-tune. Fine adjustment of the dimensions of the insole 1 is indispensable for fully exerting the functions of the insole 1.
　インソール１の寸法の微調整は靴データに基づいて行う。靴データとは、靴の種類、サイズ、つま先の捨て寸、及び各部位の寸法などを集めたデータのことである。靴のメーカや種類により、靴、中敷きなどの形状、寸法は異なる。予めこの靴データを収集しデータベースを構築することで、患者が使用する靴に合わせてインソール１の大きさを微調整することが可能となる。 Fine adjustment of the dimensions of the insole 1 is performed based on the shoe data. Shoe data is data that collects the type, size, toe discard size, and the size of each part of the shoe. The shape and dimensions of shoes, insoles, etc. differ depending on the manufacturer and type of shoes. By collecting this shoe data in advance and constructing a database, it is possible to finely adjust the size of the insole 1 according to the shoes used by the patient.
　次に、患者が使用する靴の靴データがデータベースにない場合について説明する。先ず、図１５（ａ）～（ｄ）を参照し、使用する靴の中敷き３３が取り外すことができる場合のインソール１の先端部分の寸法の微調整について説明する。（ａ）靴の中敷き３３を取り出し、（ｂ）インソール１の上面から中敷き３３を重ね合わせる。この場合、中敷き３３とインソール１とが踵の後端部分及び親指側端部で一致するように重ね合わせる。 Next, the case where the shoe data of the shoes used by the patient is not in the database will be described. First, with reference to FIGS. 15 (a) to 15 (d), fine adjustment of the dimensions of the tip portion of the insole 1 when the insole 33 of the shoe to be used can be removed will be described. (A) The insole 33 of the shoe is taken out, and (b) the insole 33 is overlapped from the upper surface of the insole 1. In this case, the insole 33 and the insole 1 are overlapped so as to coincide with each other at the rear end portion of the heel and the thumb side end portion.
　次に、（ｃ）インソール１に対して中敷き３３を踵方向に２ｍｍ程ずらし、中敷き３３のつま先の外周に沿ってインソール１の上面にガイドラインを引く。そして、（ｄ）描いたガイドラインにそって鋏３５などでカットする。 Next, (c) shift the insole 33 in the heel direction with respect to the insole 1 by about 2 mm, and draw a guideline on the upper surface of the insole 1 along the outer circumference of the toe of the insole 33. Then, (d) cut with scissors 35 or the like according to the drawn guideline.
　なお、患者の使用する靴の中敷きを取り外すことができない場合は、インソール１を靴の中に挿入した状態で患者が靴を履き、靴紐でフィット感を微調整した上で違和感がある部分を探る。そして、患者に違和感がある場合はその部分のインソール１の寸法を微調整する。患者に違和感がない場合はそのままインソール１を使用することが可能となる。 If the insole of the shoe used by the patient cannot be removed, the patient puts on the shoe with the insole 1 inserted in the shoe, fine-tunes the fit with the shoelace, and then removes the part that feels uncomfortable. explore. Then, if the patient feels uncomfortable, the size of the insole 1 in that portion is finely adjusted. If the patient does not feel uncomfortable, the insole 1 can be used as it is.
　次に図１６及び図１７を参照し、インソール１の踵部分の寸法の微調整の方法について説明する。患者の使用する靴３４の内部を実際に測定して、靴３４の内部の踵部分の幅の寸法ｄを取得する。そして、支持部材２の踵部分の幅ｗ４がｄより大きい場合は、その差の半分となる（ｗ４－ｄ）／２を支持部材２の踵部分の幅から左右均等に削除する加工を行う（図１７参照）。支持部材２の踵部分の幅ｗ４がｄ以下の場合、インソール１の踵部分の寸法の微調整は不要となる。 Next, with reference to FIGS. 16 and 17, a method for finely adjusting the dimensions of the heel portion of the insole 1 will be described. The inside of the shoe 34 used by the patient is actually measured to obtain the dimension d of the width of the heel portion inside the shoe 34. Then, when the width w4 of the heel portion of the support member 2 is larger than d, processing is performed to evenly remove (w4-d) / 2, which is half of the difference, from the width of the heel portion of the support member 2. (See FIG. 17). When the width w4 of the heel portion of the support member 2 is d or less, it is not necessary to finely adjust the dimensions of the heel portion of the insole 1.
　次に、図１８のフローチャートを参照してインソール１の製造方法について説明する。足画像取得ステップ（Ｓ１００）について以下に説明する。電子メールに添付され又は郵送などで送られてくる患者の足の写真により患者の足の画像を取得する。図１９から図２４に示す患者の足を撮影した６枚の写真を入手する。 Next, the manufacturing method of the insole 1 will be described with reference to the flowchart of FIG. The foot image acquisition step (S100) will be described below. An image of the patient's foot is obtained from a photograph of the patient's foot attached to an e-mail or sent by mail. Six photographs of the patient's feet shown in FIGS. 19 to 24 are obtained.
　図１９は、Ａ４用紙の左右両端に左右の足をそれぞれ載せて立位時の両足を上から撮影した写真である。左右の足の後端部をＡ４用紙の底辺に来るように位置を合わせる。そして、左右の足の中心線がＡ４用紙の左右両辺上に来るように左右両足の中指をそれぞれＡ４用紙の左右両辺上に来るように位置を合わせる。 FIG. 19 is a photograph of both feet in a standing position taken from above with the left and right feet placed on the left and right ends of A4 paper. Align the rear ends of the left and right feet so that they are on the bottom of the A4 paper. Then, the middle fingers of the left and right feet are aligned so as to be on the left and right sides of the A4 paper so that the center lines of the left and right feet are on the left and right sides of the A4 paper.
　Ａ４の寸法規格と対比することで患者の足の足長Ｌ（図９参照）などを採寸することができる。なお、Ａ４用紙に限定されるものではなく、Ａ３用紙、Ｂ４用紙、新聞紙など、一般的にその寸法サイズが広く知られているものであれば良い。 By comparing with the A4 dimensional standard, the foot length L of the patient's foot (see FIG. 9) can be measured. It should be noted that the paper is not limited to A4 paper, and any paper such as A3 paper, B4 paper, newspaper, etc., whose dimensions and sizes are generally well known may be used.
　図２０、２１は、足趾を真っ直ぐ伸ばした状態のそれぞれ立位時の右足、左足を内側から撮影した写真である。足趾を真っ直ぐ伸ばした状態の土踏まずのアーチの高さを測定するための写真である。図２２、２３は、足趾を背屈させた状態（ウィンドラス時）のそれぞれ立位時の右足、左足を内側から撮影した写真である。足趾を背屈させた状態（ウィンドラス時）の土踏まずのアーチの高さを測定するための写真である。 Figures 20 and 21 are photographs of the right and left feet taken from the inside when standing with the toes straight. This is a photograph for measuring the height of the arch of the foot with the toes straightened. FIGS. 22 and 23 are photographs taken from the inside of the right foot and the left foot in a standing position with the toes dorsiflexed (during windlass), respectively. This is a photograph for measuring the height of the arch of the foot when the toes are dorsiflexed (during windlass).
　図２４は、立位時の両足を後方から撮影した写真である。この写真は患者の足首の状態を診断するためのものである。足首には距骨下関節があり、距骨下関節が過回内などの症状を確認する。距骨下関節の過回内は、外反母趾、内反小趾、制限拇指、強剛拇指、足底腱膜炎、踵骨棘、種子骨炎などの足のトラブルを起こす原因になる。 FIG. 24 is a photograph of both feet while standing from behind. This picture is for diagnosing the condition of the patient's ankle. There is a subtalar joint in the ankle, and the subtalar joint confirms symptoms such as excessive pronation. Excessive pronation of the subtalar joint causes foot problems such as hallux valgus, hallux valgus, restricted thumb, tough thumb, plantar fasciitis, calcaneal spur, and sesamoiditis.
　次に、足データ取得ステップ（Ｓ１１０）について説明する。足画像取得ステップ（Ｓ１００）で取得した足画像から足データを取得する。足データとは、足の各部位にかかる寸法、サイズなどのことである。図１９の足画像から直接採寸することで足データを取得する。 Next, the foot data acquisition step (S110) will be described. Foot data is acquired from the foot image acquired in the foot image acquisition step (S100). The foot data is the dimensions, size, etc. of each part of the foot. Foot data is acquired by measuring directly from the foot image of FIG.
　左右両足の足画像から、足長の実測値Ｌ、踵底部２４の後端から拇指球２５の位置までの実測値ｍ１１、踵底部２４の後端から小指球２６の位置までの実測値ｍ２２、及び拇指球２５から小指球２６までの実測値ｍ３３を取得する。さらに、足画像の中で撮影されているＡ４用紙の長辺の長さの実測値α、及び短辺の長さの実測値βを足画像から直接採寸して取得する。 From the foot images of both left and right feet, the measured value L of the foot length, the measured value m11 from the rear end of the heel bottom 24 to the position of the ball 25, the measured value m22 from the rear end of the heel bottom 24 to the position of the hypothenar 26, And the measured value m33 from the ball 25 to the ball 26 is acquired. Further, the measured value α of the length of the long side of the A4 paper and the measured value β of the length of the short side captured in the foot image are directly measured and acquired from the foot image.
　次に、図２０から図２３の足画像を参照して、左右両足における、足の足趾を伸ばした状態における内側縦アーチ７の高さａ１、及び足の足趾を背屈させた状態（ウィンドラス時）における内側縦アーチ７の高さａ２を取得する。 Next, referring to the foot images of FIGS. 20 to 23, the height a1 of the medial longitudinal arch 7 in the state where the toes of the feet are extended and the state where the toes of the feet are dorsiflexed (in the state where the toes of the feet are extended). The height a2 of the inner vertical arch 7 at the time of windlass) is acquired.
　次に、支持部材設計ステップ（Ｓ１２０）について説明する。足データ取得ステップ（Ｓ１１０）で取得した足データに基づき、足の土踏まずに対応する位置における支持部材２の高さｈ、支持部材２の内側の長さｗ１、支持部材２の外側の長さｗ２、及び支持部材２の幅ｗ３について設計する。 Next, the support member design step (S120) will be described. Based on the foot data acquired in the foot data acquisition step (S110), the height h of the support member 2 at the position corresponding to the arch of the foot, the inner length w1 of the support member 2, and the outer length w2 of the support member 2. , And the width w3 of the support member 2 is designed.
　足の土踏まずに対応する位置における支持部材２の高さｈの設計方法については上記した式（１）を用いて行う。詳細な説明については上記の通りなのでここでの説明は省略する。支持部材２の内側の長さｗ１、支持部材２の外側の長さｗ２の設計方法については、下記の式（６）、（７）を用いて行う。既に述べたように、Ｂは定数であり０．０１から０．０３の値を取り得る。 The method of designing the height h of the support member 2 at the position corresponding to the arch of the foot is performed using the above equation (1). Since the detailed explanation is as described above, the explanation here is omitted. The design method of the inner length w1 of the support member 2 and the outer length w2 of the support member 2 is performed by using the following equations (6) and (7). As already mentioned, B is a constant and can take a value between 0.01 and 0.03.

　支持部材２の踵部分の幅寸法ｗ４の設計方法については、既に述べたように、患者の使用する靴３４の内部を実際に測定して行う。次に、患者が使用する靴３４がヒールの高い靴である場合の支持部材２の設計方法について説明する。 As for the design method of the width dimension w4 of the heel portion of the support member 2, as described above, the inside of the shoe 34 used by the patient is actually measured. Next, a method of designing the support member 2 when the shoe 34 used by the patient is a shoe having a high heel will be described.
　前述した通り、設計する支持部材２を側面視した場合において、支持部材２の踵部分の中心３８と支持部材２の後端３９とを結ぶ直線と支持部材２の踵部分の中心３８と支持部材２の後端部分の頂部４０とを結ぶ直線との間にできる角度θが、靴３４を履いた状態における拇指球２５から踵底部２４までの傾斜角度γよりも５度（deg）以上大きい場合、支持部材２の後端部分の頂部４０が低くなるように設計し、角度θと傾斜角度γとの差が５度（deg）になるようにする。 As described above, when the support member 2 to be designed is viewed from the side, the straight line connecting the center 38 of the heel portion of the support member 2 and the rear end 39 of the support member 2 and the center 38 of the heel portion of the support member 2 and the support member When the angle θ formed between the straight line connecting the top 40 of the rear end portion of 2 is 5 degrees (deg) or more larger than the inclination angle γ from the thumb ball 25 to the heel bottom 24 when the shoes 34 are worn. The top 40 of the rear end portion of the support member 2 is designed to be low so that the difference between the angle θ and the inclination angle γ is 5 degrees (deg).
　次に、支持部材成形ステップ（Ｓ１３０）について説明する。支持部材の成形は３Dプリンタにより行う。３Ｄプリンタで用いる材料等については上述した通りである。３Dプリンタを用いることにより、医師や理学療法士が考案したアルゴリズムに足データ取得ステップ（Ｓ１１０）で取得した足データを入力することで患者に最適なインソール１を遠隔で作ることができる。 Next, the support member forming step (S130) will be described. The support member is molded by a 3D printer. The materials and the like used in the 3D printer are as described above. By using a 3D printer, it is possible to remotely create an optimal insole 1 for a patient by inputting the foot data acquired in the foot data acquisition step (S110) into an algorithm devised by a doctor or a physiotherapist.
　次に、クッション部材接合ステップ（Ｓ１４０）及びカバー部接合ステップ（Ｓ１５０）について説明する。支持部材成形ステップ（Ｓ１３０）で成形された支持部材２の上表面にクッション部材３を接着剤などで合着する。その後、クッション部材３の上面からカバー部４を接着剤などで合着する。 Next, the cushion member joining step (S140) and the cover portion joining step (S150) will be described.

After that, the cover portion 4 is bonded from the upper surface of the cushion member 3 with an adhesive or the like.
　次に、インソール成形ステップ（Ｓ１６０）について説明する。ここでは靴データに基づいてインソール１の寸法の微調整を行う。なお、インソール１の寸法の微調整については既に述べた通りでありここでの詳述は省略する。患者が使用する靴の靴データがデータベースにない場合は、既に詳述するように、患者が使用する靴３４若しくはその中敷き３３から採寸してインソール１の寸法の微調整を行う。 Next, the insole molding step (S160) will be described. Here, the dimensions of the insole 1 are finely adjusted based on the shoe data. The fine adjustment of the dimensions of the insole 1 has already been described, and details thereof will be omitted here. If the shoe data of the shoes used by the patient is not in the database, the dimensions of the insole 1 are fine-tuned by measuring from the shoes 34 used by the patient or the insole 33 thereof, as described in detail above.
　上記した実施の形態によれば、患者の足を撮影した６枚の足画像に基づいて患者の足の骨格に適合するインソール１を作ることができるので、遠隔地にいる患者のためにインソール１を作ることが可能となる。 According to the above embodiment, the insole 1 that fits the skeleton of the patient's foot can be made based on the six foot images of the patient's foot, so that the insole 1 can be used for a patient in a remote place. It becomes possible to make.
