Description
本発明は、前方横アーチを刺激し外側縦アーチ、内側縦アーチ全体を矯正し、筋力をトレーニングする方法及びそれに用いる履物に関するものである。 The present invention relates to a method for stimulating a front lateral arch to correct an outer longitudinal arch and an entire inner longitudinal arch, and training muscular strength, and footwear used therefor.
人間の足裏には前方横アーチ、外側縦アーチ、内側縦アーチのアーチ構造が備えられている。図３Ａにおいて、前方横アーチＦＡ、外側縦アーチＯＡ、内側縦アーチＩＮを示した。運動不足などによりアーチ構造が崩れてしまうと足に加わる衝撃を十分に吸収できなくなることで、疲れやすくなるなどの問題があり、それを解消する為に、足が接する面をアーチ形状にさせた履物や中敷きが提案されている（特許文献１）。
また、歩行時にアキレス腱を伸ばし、健康増進、リハビリ等を行うため、履物底について、つま先側を踵側よりも高く構成した履物が提案されている（特許文献２）。
また、つま先側を踵側よりも高くした履物であって、アキレス腱を伸ばす量を自由に変更できるようにした履物が提案されている（特許文献３）。
A human foot has an arch structure of a front lateral arch, an outer longitudinal arch, and an inner longitudinal arch. In FIG. 3A, the front horizontal arch FA, the outer vertical arch OA, and the inner vertical arch IN are shown. If the arch structure collapses due to lack of exercise, etc., it will not be able to absorb the shock applied to the foot enough, causing problems such as becoming easy to get tired, and in order to solve it, the surface where the foot touches was made arched Footwear and insoles have been proposed (Patent Document 1).
In addition, in order to stretch the Achilles tendon during walking and promote health, rehabilitation, and the like, there has been proposed a footwear in which the toe side is configured to be higher than the heel side (Patent Document 2).
In addition, there has been proposed a footwear in which the toe side is higher than the heel side, and the amount of stretching the Achilles tendon can be freely changed (Patent Document 3).
しかし、アーチ構造の崩れを解消するには運動により筋肉を鍛える必要があるが、従来の履物で歩いただけでは、砂浜の歩き難さや、山道での上り坂環境で得られる効率的な筋力強化を得られるものではない。
本発明は、平らな道の散歩でありながら、砂浜や上り坂を体現できる抗重力筋を強化するトレーニングする方法及びそれに用いる履物を提供することを目的とする。
However, in order to eliminate the collapse of the arch structure, it is necessary to train the muscles by exercise, but walking with conventional footwear makes it difficult to walk on the sandy beach and efficient muscle strengthening that can be obtained in uphill environments on mountain roads. It is not obtained.
An object of the present invention is to provide a training method for strengthening anti-gravity muscles that can embody sandy beaches and uphills while walking on a flat road, and footwear used therefor.
上記目的を達成するために、足に履物を履いた状態で歩行することにより前方横アーチを刺激し筋力をトレーニングする方法であって、
足が地面に接地した際に踵側に対してつま先側が高い状態に足裏を傾斜状態に前記履物のソールにより支持し、
少なくとも親指の直下のソール部分を柔軟材料若しくは弾性素材で形成し、前記ソールの親指を他の指から離間させる若しくは前記ソールの親指の範囲を他の指の範囲に対して独立して動くようにして、足が地面を蹴り出す際に親指を他の指から分離して沈み込ませることにより足の前方横アーチを強制的に動かすことを特徴とする筋力をトレーニングする。
In order to achieve the above object, a method of stimulating the front lateral arch by walking with footwear on the foot and training muscle strength,
When the foot touches the ground, the sole of the foot is supported by the sole of the foot in an inclined state with the toe side being higher than the heel side,
At least the sole portion directly below the thumb is made of a flexible material or an elastic material so that the thumb of the sole is separated from the other fingers or the range of the thumb of the sole moves independently of the range of the other fingers. Thus, when the foot kicks off the ground, the muscle strength is trained by forcibly moving the front lateral arch of the foot by causing the thumb to separate and sink from the other fingers.
この発明によれば、つま先側が高い傾斜のソールにより、土踏まずに重心が移行することで姿勢が伸び、腹筋背筋を刺激することができる。親指が他の指から分離し、親指が沈むことで前方横アーチを強化することができる。ソールの働きにより内外の縦アーチを強化することができる。裸足感覚で路面形状に沿った凹凸感を足裏で受け取ることができるとともに、柔軟的に足裏の前方横アーチを刺激し活性化することができる。 According to the present invention, the posture can be extended by stimulating the abdominal muscles and the back muscles by shifting the center of gravity without the arch by the sole having a high inclination on the toe side. The front lateral arch can be strengthened by separating the thumb from other fingers and sinking the thumb. The inner and outer vertical arches can be strengthened by the action of the sole. A feeling of unevenness along the road surface shape can be received by the soles in a bare foot sense, and the front lateral arch of the soles can be flexibly stimulated and activated.
以下、実施例１について、図１〜図４に基づいて説明する。
図１は本実施例に係る履物１の平面図で、図２は本実施例に係る履物の側面図である。履物１は本体２とソール３からなり、本体２はゴム素材からなり、つま先部が親指を挿入する部分４と他の指を挿入する部分５の二股に分けられた足袋型を形成している。本体２は、足の甲、側面、踵の背中側を包囲し、柔軟性を持って、足の甲をソール３に対して押しつけて固定し、かつ踵の背中がズレないようにしている。本体２の部分４及び部分５は、指の動きを若干許容できるように空間が設けられている。
Hereinafter, Example 1 is demonstrated based on FIGS. 1-4.
FIG. 1 is a plan view of a footwear 1 according to this embodiment, and FIG. 2 is a side view of the footwear according to this embodiment. The footwear 1 is composed of a main body 2 and a sole 3, and the main body 2 is made of a rubber material, and the toe portion forms a tabi type divided into two parts, a part 4 for inserting a thumb and a part 5 for inserting another finger. . The main body 2 surrounds the instep, side, and back side of the heel, has flexibility, presses the instep back against the sole 3, and fixes the back of the heel. A space is provided in the portion 4 and the portion 5 of the main body 2 so as to allow a slight movement of the finger.
ソール３は柔軟素材若しくは弾性素材である発泡ゴムからなり、ソール３の厚さは前記つま先側から踵側にむかって厚さを減少するように傾斜している。ソール３が接地したときには、ソール３の上側の面は、つま先側が高く、踵側が低く傾斜するようになっている。ソール３が発泡ゴムであるため、高反発で衝撃吸収、形状回復力を有し、裸足感覚で路面形状に沿った凹凸感を足裏で受けることが可能となる。つま先側が高い傾斜であるため、平らな地面でも上り坂の環境を作ることでき、土踏まずに重心が移行し、姿勢が伸び腹筋背筋を刺激することができる。土踏まずの位置に重心があれば、足の縦アーチ部分に加重することで衝撃を吸収分散し足首膝関節、腰の負担を軽減することができる。前方に踏み込むと、足首から甲部、足裏の屈曲幅が拡大し、外側縦アーチ、内側縦アーチが活性化される。 The sole 3 is made of foamed rubber which is a flexible material or an elastic material, and the thickness of the sole 3 is inclined so as to decrease from the toe side toward the heel side. When the sole 3 is grounded, the upper surface of the sole 3 is inclined such that the toe side is high and the heel side is low. Since the sole 3 is made of foamed rubber, it has high resilience, absorbs impact, and has shape recovery power, and can receive a feeling of unevenness along the road surface shape with the sole of the foot as if barefoot. Since the toe side has a high inclination, it is possible to create an uphill environment even on flat ground, the center of gravity shifts to the arch, and the posture is extended to stimulate the abdominal muscles. If there is a center of gravity at the position of the arch, it is possible to absorb and disperse the impact by applying weight to the vertical arch part of the foot, thereby reducing the burden on the ankle knee joint and waist. When stepped forward, the bending width of the ankle, upper part and sole is increased, and the outer vertical arch and the inner vertical arch are activated.
図３は、歩行時における足裏の重心移動と履物１の作用を模式的に示している。図３（ｂ）にはソールがフラットな履物を履いた際の歩行の様子を示している。図３（ａ）において、重心は足裏が接地すると踵から親指に向かって曲線Ｓに示すような軌跡で重心Ｇが移動する。図３（ｂ）はソールがフラットな履物１０を履いたときの足の動きを、図３（ｃ）は本実施例に係る履物１を履いたときの足の動きを示している。 FIG. 3 schematically shows the movement of the center of gravity of the sole and the action of the footwear 1 during walking. FIG. 3 (b) shows a state of walking when the footwear is worn with a flat sole. In FIG. 3A, when the sole touches the center of gravity, the center of gravity G moves along a locus as shown by a curve S from the heel toward the thumb. FIG. 3B shows the movement of the foot when wearing the footwear 10 with a flat sole, and FIG. 3C shows the movement of the foot when wearing the footwear 1 according to this embodiment.
図３（ｂ）と図３（ｃ）を比較すると、足が地面に接地した場合には（図中ｐ）、フラットな履物１０では重心は真下にかかるが、つま先側が高く踵側が低く傾斜した特許文献２や３の履物と同様に履物１では重心Ｇの真下に接地した足がこないから、胸を張って重心を前に出そうと反射する。接地した足が後側にくると（図中ｑ）つま先の関節が曲がってゆく。重心Ｇは次第につま先に移ってゆく。フラットな履物１０では蹴り出しの準備がされるが、履物１ではソール３が柔らかいため、つま先がソール３に沈み込んでゆく。これについては図４で後に説明する。前側の足が地面に接地すると（図中ｒ）、フラットな履物１０では蹴り出しが行われるが、履物１では、後側の足に重心Ｇが残った状態で蹴り出しが行われる。
図３に示す足の動きは、標準的な動きであるが、足の裏を接地したままで歩行したり、歩幅が狭い老人に対しても、つま先側が高く踵側が低く傾斜することで、足の親指に自然に体重をかける動作になるように作用する。
Comparing FIG. 3 (b) and FIG. 3 (c), when the foot is in contact with the ground (p in the figure), the center of gravity of the flat footwear 10 is directly below, but the toe side is high and the heel side is inclined low. Similarly to the footwear of Patent Documents 2 and 3, in the footwear 1, since the grounded foot does not come directly under the center of gravity G, it reflects when trying to bring the center of gravity forward by stretching the chest. When the grounded foot comes to the rear (q in the figure), the joint of the toe bends. The center of gravity G gradually moves to the toes. The flat footwear 10 is prepared for kicking out, but in the footwear 1, the sole 3 is soft, so the toes sink into the sole 3. This will be described later with reference to FIG. When the front foot comes in contact with the ground (r in the figure), the flat footwear 10 kicks out, but the footwear 1 kicks out with the center of gravity G remaining on the rear foot.
The movement of the foot shown in FIG. 3 is a standard movement, but even when walking with the sole of the foot in contact with the ground or when the toe side is high and the heel side is low, Acts to put weight on the thumb naturally.
図４は本実施例に係る履物１のつま先が二股に分かれる根元の位置Ｘ−Ｘにおける断面図であり、履物１を着用して運動した状態のつま先部分の変化を示している。本体２により足の甲は、その全体をソールに押しつけられているため、指は上下には動かせるが足の裏はソールに固定されている状態である。 FIG. 4 is a cross-sectional view at the base position XX where the toe of the footwear 1 according to the present embodiment is divided into two forks, and shows a change in the toe portion in a state in which the footwear 1 is worn and exercised. Since the entire instep of the instep is pressed against the sole by the main body 2, the finger can be moved up and down, but the sole of the foot is fixed to the sole.
図４（ａ）は立っている状態で、図４（ｂ）は踏み込んだ状態の図である。図３（ｃ）のｑの状態に足があると、踏み込んだ際に親指がソール３に沈みはじめる。本実施例の履物１では、本体２が足袋型になっているため、まず、親指と他の指との間が離れており、他の指と連動しないようになっている。そして、足袋であるため、親指が他の指に対して独立して動く。足の裏を移動する重心の軌跡が足裏を離れる際には、親指の位置に重心が来ているため、親指は他の指に対して大きくソール３に沈む。履物１は、親指を挿入する部分４が分かれた構成となっているため、親指は、矢印ｔに示すように内側に回転しながら沈み込むことになる。本実施例の履物１では、その沈む量ｄはソールの厚さの３０％程度とした。このように、歩くだけで親指の上下運動が可能となり、この運動により、前方横アーチが強制的に動かされ、アーチを矯正できる。 FIG. 4A is a standing state, and FIG. 4B is a stepped state. If there is a foot in the state of q in FIG. 3 (c), the thumb begins to sink into the sole 3 when it is stepped on. In the footwear 1 of the present embodiment, since the main body 2 has a tabi shape, first, the thumb and the other finger are separated from each other, and are not interlocked with the other finger. And since it is a tabi, a thumb moves independently with respect to another finger. When the trajectory of the center of gravity that moves on the sole of the foot leaves the sole, the center of gravity comes to the position of the thumb, so that the thumb sinks greatly into the sole 3 with respect to the other fingers. Since the footwear 1 has a structure in which a portion 4 into which the thumb is inserted is separated, the thumb sinks while rotating inward as indicated by an arrow t. In the footwear 1 of the present example, the sinking amount d is about 30% of the thickness of the sole. Thus, the thumb can be moved up and down only by walking, and the front lateral arch is forcibly moved by this movement, and the arch can be corrected.
実施例１の履物１は、６０−６５ｋｇの体重を想定したサイズ２６ｃｍの履物であり、つま先のソール３の厚さ２ｃｍに（踵は１ｃｍである）対して、６ｍｍ沈み込んだ。沈む量ｄは、図３（ｃ）の図中ｒに示すように全体重が親指に乗った状態において、少なくとも親指が他の指に対して下方への移動する移動量に相当である（尚、他の指は殆どソール３には沈み込まない）。前方横アーチを強制的に動かすには、４ｍｍ以上、下方へ親指が移動すれば十分であって、必要があればさらに沈む量ｄが大きくなるように、ソール３を調整しても良い。ソール３は、発泡ゴムを使用しているため、ゴム中に含まれる気泡が潰れることにより人間の体重により可逆的に圧縮変形することができる。他のクッション性素材に比べて、ソールの材質としては発泡ゴムが適当である。
なお、少なくとも親指の直下の位置が発泡ゴムのような柔軟材料若しくは弾性素材であればよく、実施例１のようにソール全体を発泡ゴムにする必要は無い。親指の箇所以外については、圧縮によって大きく沈み込ませる必要は無いからである。また、本体２は、ゴム素材が好ましいが、足を保持すればよく、布や革を素材にして形成された足袋型でも良い。
The footwear 1 of Example 1 is a footwear having a size of 26 cm assuming a weight of 60 to 65 kg, and sinks 6 mm into the thickness 2 cm of the toe sole 3 (the heel is 1 cm). The amount d of sinking is equivalent to the amount of movement that at least the thumb moves downward relative to the other fingers when the total weight is on the thumb as indicated by r in FIG. The other fingers hardly sink into the sole 3). To forcibly move the front lateral arch, it is sufficient if the thumb moves downward by 4 mm or more, and if necessary, the sole 3 may be adjusted so that the amount d that sinks further increases. Since the sole 3 uses foamed rubber, it can be reversibly compressed and deformed by the human weight when the bubbles contained in the rubber are crushed. Compared to other cushioning materials, foamed rubber is suitable as the material for the sole.
It should be noted that at least the position immediately below the thumb may be a flexible material such as foam rubber or an elastic material, and the entire sole need not be made of foam rubber as in the first embodiment. This is because it is not necessary to greatly sink the portion other than the thumb portion by compression. The main body 2 is preferably made of a rubber material. However, the main body 2 only needs to hold a foot, and may be a tabi type formed from cloth or leather.
履物１の着用の感想として、「歩行後１〜２分で下腿三頭筋に張りを感じる。」、「歩行後１０分前後で発汗前のポカポカ感が出る。」、「歩行２０分前後で背筋が伸びた姿勢を実感する。」、「歩行後２５分前後で大腿四頭筋の張りを感じる。」、「３０分で終了。軽い汗をかき、大腿二頭筋あたりに軽い張りを感じる。ジョギングをした後に残る足腰の疲労感があるが、息づかいは普通。」などがある。 As impressions of wearing footwear 1, “I feel tension in the triceps surae in 1 to 2 minutes after walking.” “I feel a feeling of sweat before sweating around 10 minutes after walking.” "I feel the posture where my back muscles are stretched." There is a feeling of tiredness of the legs that remains after jogging, but breathing is normal. "
上記実施例においては、本体２は足袋型を形成していたが、親指を独立して動かす為には、他の構成であっても良い。図５に実施例２による履物１１を示す。図５（ａ）は平面、図５（ｂ）、５（ｃ）はＹ１−Ｙ１断面、図５（ｄ）はＹ２−Ｙ２断面を示している。履物１１は、本体１２は親指と他の指を分けておらず、足の指全体を包むものとなっている。一方で、距離を離して親指と他の指を分離するセパレータ１５をソール１３から立設し本体１２の内側に取り付けている。セパレータ１５は、図に示したセパレータ１５は中空であるが、柔軟性があれば中空でなくてもかまわない。本体１２は、布又は革で有り足の保持力は実施例１の本体２と比べて低いため、足に対して余裕を持って形成されている。ソール１３は、先の実施例と同様に、発泡ゴムを使用しているが、他の柔軟素材若しくは弾性素材でも良い。また、全体を柔軟素材若しくは弾性素材にしなくとも、親指の直下だけが沈み込めば良いため、少なくとも親指の直下だけ例えばコイルバネのような柔軟素材若しくは弾性素材を仕込んだものでも良い。 In the embodiment described above, the main body 2 has a tabi shape, but other configurations may be used to move the thumb independently. FIG. 5 shows footwear 11 according to the second embodiment. 5A is a plan view, FIGS. 5B and 5C are Y1-Y1 cross sections, and FIG. 5D is a Y2-Y2 cross section. In the footwear 11, the main body 12 does not separate the thumb and other fingers, and wraps the entire toes. On the other hand, a separator 15 that separates the thumb and other fingers at a distance is erected from the sole 13 and attached to the inside of the main body 12. Although the separator 15 shown in the drawing is hollow, the separator 15 may not be hollow as long as it has flexibility. The main body 12 is made of cloth or leather, and the holding force of the foot is lower than that of the main body 2 of the first embodiment. The sole 13 uses foamed rubber as in the previous embodiment, but may be other flexible material or elastic material. In addition, even if the whole is not made of a flexible material or an elastic material, it is only necessary to sink just under the thumb, so that a material made of a flexible material or an elastic material such as a coil spring at least directly under the thumb may be used.
図５（ｃ）に示すように足を踏み込んだ際には、セパレータ１５により親指と他の指との間が離れており、他の指と連動しないようになっており、親指が他の指に対して独立して動きはじめる。足の裏を移動する重心の軌跡が足裏を離れる際には、親指の位置に重心が来ているため、親指は他の指に対して大きくソール３に沈む。本体１２の甲の部分が引張され、親指は、矢印ｔに示すように内側に回転しながら沈み込む。このように、実施例１の履物１のように、前方横アーチが強制的に動かされ、アーチの矯正が可能となる。本体１２の甲の部分の柔軟度が、履物１に比べて劣るものとなるが、本体１２の形状が通常の靴の形状に出来るので、外出時に人目が気にならないという効果がある。 When the foot is stepped on as shown in FIG. 5 (c), the separator 15 separates the thumb from the other finger so that it does not interlock with the other finger. Begins to move independently. When the trajectory of the center of gravity that moves on the sole of the foot leaves the sole, the center of gravity comes to the position of the thumb, so that the thumb sinks greatly into the sole 3 with respect to the other fingers. The upper part of the main body 12 is pulled, and the thumb sinks while rotating inward as indicated by an arrow t. Thus, like the footwear 1 of the first embodiment, the front lateral arch is forcibly moved, and the arch can be corrected. Although the flexibility of the instep portion of the main body 12 is inferior to that of the footwear 1, the shape of the main body 12 can be made into the shape of a normal shoe, so that there is an effect that the human eye is not concerned when going out.
図６に実施例３による履物２１を示す。図６（ａ）は平面、図６（ｂ）、６（ｃ）はＺ１−Ｚ１断面、図６（ｄ）はＺ２−Ｚ２断面を示している。履物２１は、履物１１と同様に本体２２は親指と他の指を分けておらず、全体を包むものとなっている。一方で、ソール２３が親指の直下となる親指の輪郭範囲２３１だけ切り離され、ソール２３における他の指の直下の箇所に対して独立して動くようになっている。尚、ソール２３は、先の実施例と同様に、発泡ゴムを使用している。本体２２は、布又は革で有り実施例１の本体２と比べて足の保持力は低く、足に対して若干の余裕を持って形成されている。また、切り離しの場所は、親指の輪郭の範囲であり、親指の根元の部分２３２は、切り離していても或いは連続していても良い。部分２３２を含めて親指の輪郭を完全にソール２３から切り離す場合には、ソール２３の下に底材２５を貼り付けておくのが良い。また、少なくとも親指の部分は他のソール２３の箇所と構成を異ならせて、親指の部分のみの沈み込みを促進させても良い。親指の箇所以外については、圧縮によって大きく沈み込ませる必要は無いからである。 FIG. 6 shows footwear 21 according to the third embodiment. 6A is a plan view, FIGS. 6B and 6C are Z1-Z1 cross sections, and FIG. 6D is a Z2-Z2 cross section. The footwear 21, like the footwear 11, does not separate the thumb and other fingers from the main body 22, and wraps the entire footwear 21. On the other hand, the sole 23 is cut away only by the outline region 231 of the thumb that is directly below the thumb, and moves independently with respect to the portion of the sole 23 immediately below the other fingers. The sole 23 uses foamed rubber as in the previous embodiment. The main body 22 is made of cloth or leather and has a lower holding force than the main body 2 of the first embodiment, and is formed with a slight margin with respect to the foot. Further, the place of separation is the range of the outline of the thumb, and the base portion 232 of the thumb may be separated or continuous. In the case where the outline of the thumb including the portion 232 is completely separated from the sole 23, the bottom material 25 may be pasted under the sole 23. Further, at least the thumb portion may be configured differently from the other sole 23 to promote the sinking of only the thumb portion. This is because it is not necessary to greatly sink the portion other than the thumb portion by compression.
図６（ｃ）に示すように足を踏み込んだ際には、親指の輪郭範囲だけが圧縮され、他のソール２３の箇所と連動しないで沈みはじめる。足の裏を移動する重心の軌跡が足裏を離れる際には、親指の位置に重心が来ているため、親指は他の指に対して大きな圧縮力を発揮してソール２３に沈む。親指の輪郭が他の部分と分離しているので、この沈み込みは他の部分には伝搬が抑制される。本体２２の甲の部分が引張されるのは、履物１１と同じである。このように、実施例１の履物１のように、前方横アーチが強制的に動かされ、アーチの矯正が可能となる。 When the foot is stepped on as shown in FIG. 6 (c), only the outline range of the thumb is compressed and begins to sink without being interlocked with other portions of the sole 23. When the locus of the center of gravity that moves on the sole of the foot leaves the sole, the center of gravity is at the position of the thumb, so that the thumb sinks into the sole 23 with a large compressive force exerted on the other fingers. Since the contour of the thumb is separated from other parts, this subduction is prevented from propagating to other parts. It is the same as the footwear 11 that the upper part of the main body 22 is pulled. Thus, like the footwear 1 of the first embodiment, the front lateral arch is forcibly moved, and the arch can be corrected.
