It is getting thinner.
この発明の靴中底を構成する前足部２５から中足部２７、中足部２７、後足部２９を機能的にサポートする形状を持った発泡合成ゴム製パッドの形状について説明する。パッドＡ７は、図１（Ｄ）に示されているように靴中底本体Ａ９の上面に設定され、前足部２５から後足部２９にわたって位置する。図５は右足用の形状であるが、図５（Ａ）の平面図のように、上述の3種類のパッドＡ１、Ａ３、Ａ５を滑らかに組み合わせ、一体にした形状になっている。さらに、図５（Ｂ）のＡ−Ａ’断面図、図５（Ｃ）のＢ−Ｂ’'断面図、図５（Ｄ）のＣ−Ｃ’断面図、図５（Ｅ）のＤ−Ｄ’断面図に示されている形状においても同様である。 The shape of the foamed synthetic rubber pad having a shape that functionally supports the front foot portion 25 to the middle foot portion 27, the middle foot portion 27, and the rear foot portion 29 constituting the shoe insole of the present invention will be described. As shown in FIG. 1D, the pad A7 is set on the upper surface of the shoe midsole body A9 and is located from the front foot portion 25 to the rear foot portion 29. FIG. 5 shows the shape for the right foot, but as shown in the plan view of FIG. 5 (A), the above-mentioned three types of pads A1, A3, A5 are smoothly combined to form an integrated shape. Further, FIG. 5B is a cross-sectional view taken along line AA ′, FIG. 5C is a cross-sectional view taken along line BB ″, FIG. 5D is a cross-sectional view taken along line CC ′, and FIG. The same applies to the shape shown in the D ′ sectional view.
これらのパッドを靴中底本体Ａ９上面に加硫一体形成するが、このときの単一または任意の組み合わせについて説明する。最大7種類のパッド形状があるもので、パッドＡ１［図１（Ａ）］のみ、パッドＡ３［図１（Ｂ）］のみ、パッドＡ５［図１（Ｃ）］のみ、パッドＡ１とパッドＡ３、パッドＡ１とパッドＡ５、パッドＡ３とパッドＡ５、パッドＡ１とパッドＡ３およびパッドＡ５の3つの組み合わせであるパッドＡ７［図１（Ｄ）］がある。 These pads are integrally vulcanized on the upper surface of the insole body A9. A single or arbitrary combination at this time will be described. There are a maximum of 7 types of pad shapes, only pad A1 [FIG. 1 (A)], only pad A3 [FIG. 1 (B)], only pad A5 [FIG. 1 (C)], pad A1 and pad A3, There is a pad A7 [FIG. 1 (D)] which is a combination of the pad A1 and the pad A5, the pad A3 and the pad A5, the pad A1 and the pad A3, and the pad A5.
図７（Ａ）、図７（Ｂ）および図７（Ｃ）により、前足部２５から中足部２７を機能的にサポートする形状を持った発泡合成ゴム製パッドＡ１の機能を説明する。図７（Ａ）は右足用の形状であるが、靴木型Ａ１３の前足部２５の底面形状は、本来、足の横アーチ３１構造により、上に凸であるべきだが、もしパッドＡ１がなければ、図７（Ｂ）に示されているように、靴の展示美観上および製靴上、下に凸になっている。この結果、足部の横アーチ３１の扁平化を誘発し、痛みやタコを生じさせ、足骨格は開張足へと変形が進行する。靴の展示美観上および製靴上の都合と、足部の横アーチ３１の扁平化の防止を両立させるため、靴の外観上は下に凸を保持しながら、パッドＡ１と一体化した靴中底本体Ａ９の接足面３７は、図７（Ｃ）に示されているように、上へ凸とすることにより、足の横アーチ３１を保持して解剖学的に適合させることができる。 7A, 7B, and 7C, the function of the foamed synthetic rubber pad A1 having a shape that functionally supports the front foot portion 25 to the middle foot portion 27 will be described. Although FIG. 7A shows the shape for the right foot, the bottom shape of the forefoot portion 25 of the shoe mold A13 should originally be convex upward due to the structure of the lateral arch 31 of the foot, but if there is no pad A1 For example, as shown in FIG. 7B, the shoe is convex on the display aesthetics of the shoe and on the shoe making. As a result, flattening of the lateral arch 31 of the foot portion is induced, causing pain and octopus, and the foot skeleton is deformed into an open foot. The shoe insole that is integrated with the pad A1 while keeping the convexity downward on the appearance of the shoe in order to balance the aesthetics and shoemaking of the shoe and the prevention of flattening of the lateral arch 31 of the foot. As shown in FIG. 7C, the contact surface 37 of the main body A9 is convex upward, so that the lateral arch 31 of the foot can be held and anatomically adapted.
図８（Ａ）、図８（Ｂ）および図８（Ｃ）により、中足部２７を機能的にサポートする形状を持った発泡合成ゴム製パッドＡ３の機能を説明する。図８（Ａ）は右足用の形状であるが、足部の内側縦アーチ３３および外側縦アーチ３５を保持する形状を有する。もしパッドＡ３がなければ、図８（Ｂ）に示されるように、内側縦アーチ３３が低下する。 8A, 8B, and 8C, the function of the foamed synthetic rubber pad A3 having a shape that functionally supports the midfoot portion 27 will be described. FIG. 8A shows the shape for the right foot, but has a shape that holds the inner vertical arch 33 and the outer vertical arch 35 of the foot. If the pad A3 is not present, the inner longitudinal arch 33 is lowered as shown in FIG.
また靴のヒールが高くなると、主に内側縦アーチ３３が高くなるので、単位面積当たりの体重負荷量が増加し、タコや痛みの原因となる。このため、図８（Ｃ）に示されるように、中足部２７を機能的にサポートする形状を持った発泡合成ゴム製パッドＡ３によって、接触面積を増大させることにより、単位面積当たりの体重負荷量を減少させて、この問題を解消することができる。 Further, when the heel of the shoe is increased, the inner longitudinal arch 33 is mainly increased, so that the weight load per unit area increases, which causes octopus and pain. For this reason, as shown in FIG. 8 (C), by increasing the contact area with the foamed synthetic rubber pad A3 having a shape that functionally supports the middle foot 27, the weight load per unit area is increased. The amount can be reduced to eliminate this problem.
例えば、ローヒール靴による歩行では踵から地面に接地し、踵の軟部組織が適度に潰れることによって、歩行の初期の安定化を行っているが、例えばハイヒール靴による歩行では、つま先と踵がほぼ同時に接地するため、この踵の軟部組織による安定化が図れず、接地直後の踵の左右方向のバランスが不安定となり、続く蹴り出しへの円滑な歩行運動が安定しない。さらにこの不安定要素は、足関節捻挫や靴ズレなどを誘発する。 For example, in walking with low heel shoes, the heel softly touches the ground, and the soft tissue of the heel is appropriately crushed to stabilize the initial walking.For example, in walking with high heel shoes, the toes and the heel are almost simultaneously Since the heel is grounded, the heel cannot be stabilized by the soft tissue, and the right-and-left balance of the heel immediately after the ground becomes unstable, and the smooth walking motion to the subsequent kick is not stable. Furthermore, this unstable element induces ankle sprains and shoe slippage.
図９（Ａ）および図９（Ｂ）により、上述の問題がある後足部２９を機能的にサポートする形状を持った発泡合成ゴム製パッドＡ５の機能を説明する。図９（Ａ）は右足用の形状であるが、図９（Ｂ）に示されるように、踵を包み込むようにサポートして安定化を増進させ、かつ、踵と靴中底本体Ａ９の接触が密になることにより、局所的圧力集中を分散させ、角質化や痛みを防止することができる。 9A and 9B, the function of the foamed synthetic rubber pad A5 having a shape that functionally supports the rear foot portion 29 having the above-described problems will be described. FIG. 9 (A) shows the shape for the right foot, but as shown in FIG. 9 (B), the heel is supported so as to wrap it and the stabilization is improved, and the contact between the heel and the insole main body A9 is achieved. By becoming dense, local pressure concentration can be dispersed and keratinization and pain can be prevented.
図１０により、前足部２５から中足部２７、中足部２７、後足部２９を機能的にサポートする形状を持った発泡合成ゴム製パッドＡ７の機能について説明する。図１０は右足用の形状であるが、上述のパッドＡ１、パッドＡ３、パッドＡ５の組み合わせ例として、図１０に示されるように、パッドＡ７があり、横アーチ３１、内側縦アーチ３３、外側縦アーチ３５を的確に保持しすることにより、各々のパッドの効果を合わせ持つ。 The function of the foamed synthetic rubber pad A7 having a shape that functionally supports the front foot portion 25 to the middle foot portion 27, the middle foot portion 27, and the rear foot portion 29 will be described with reference to FIG. FIG. 10 shows the shape for the right foot, but as an example of the combination of the above-described pad A1, pad A3, and pad A5, as shown in FIG. 10, there is a pad A7, which is a lateral arch 31, an inner longitudinal arch 33, an outer longitudinal arch. By holding the arch 35 accurately, the effects of each pad are combined.
図１１により、靴中底の製造方法について説明する。予め製造された靴中底本体Ａ９を雌金型Ａ１７内においた後、靴中底本体Ａ９上面へ、例えばパッドＡ３の原材料である発泡合成ゴムを適宜配置し、雄金型Ａ１５を例えば雌金型Ａ１７に対して下降させて、例えば約１５０℃で８〜１０分、約３ｔの圧力により、加熱圧力を加え、発泡合成ゴムに加硫加工を施すことによって製造される。これにより各々のパッド位置は、手作業とは異なり、前後ないしは左右の不同を生じず、かつ発泡合成ゴムは左右均一な硬度を保つことができる。また、パッド辺縁部と靴中底本体Ａ９上面に図１２に示したような明らかな段差が生じず、滑らかな表面をつくることができる。さらに、予め準備された金型を使用することにより、各パッドの単一または組み合わせにより多様な形態をなしうるため、コストの低減および納期を短縮することができる。 A method for manufacturing a shoe insole will be described with reference to FIG. After the pre-manufactured shoe insole body A9 is placed in the female mold A17, foamed synthetic rubber that is a raw material of the pad A3, for example, is appropriately disposed on the upper surface of the shoe insole body A9, and the male mold A15 is, for example, a female mold For example, it is manufactured by lowering the mold A17 and applying a heating pressure at a pressure of about 3 tons at about 150 ° C. for 8 to 10 minutes to vulcanize the foamed synthetic rubber. As a result, each pad position is different from the manual operation, so that there is no difference between front and rear or left and right, and the foamed synthetic rubber can maintain a uniform hardness on the left and right. In addition, a clear step as shown in FIG. 12 does not occur between the pad edge and the upper surface of the shoe midsole body A9, and a smooth surface can be created. Furthermore, by using a mold prepared in advance, a variety of forms can be made by using a single pad or a combination of the pads, so that cost reduction and delivery time can be shortened.
この発明の靴について説明する。前足部２５から中足部２７、中足部２７、後足部２９を各々機能的にサポートする形状を持った発泡合成ゴム製パッドＡ１（Ａ３、Ａ５、Ａ７）を、靴中底本体Ａ９上面に単一または任意の組み合わせにより形成された靴中底を内蔵した靴において、各々のパッド位置は手作業と異なり、前後ないしは左右の不同を生じず、左右均一な硬度を保つことができる。また、靴中底本体Ａ９上面は、パッド辺縁部と靴中底本体Ａ９上面に図１２に示したような明らかな段差が生じず、滑らかな表面になるため、足裏と靴中底本体Ａ９上面の接触が密接で使用感がよい。さらに靴中底本体Ａ９上面に貼付する中敷にシワや段差を生じないため、靴展示上、美しい外観を呈することができる。 The shoe of the present invention will be described.

In a shoe having a built-in shoe insole formed in a single or arbitrary combination, each pad position is different from manual work, and does not cause front-rear or left-right inconsistency, and can maintain a uniform left-right hardness. Further, the upper surface of the shoe insole body A9 has a smooth surface as shown in FIG. 12 on the pad edge and the upper surface of the shoe insole body A9. The contact on the upper surface of A9 is close and the feeling of use is good. Furthermore, since wrinkles and steps do not occur in the insole attached to the upper surface of the shoe midsole main body A9, a beautiful appearance can be exhibited in the shoe display.
