Description

本発明は、歩行時に足の筋肉に通常より下肢に大きな負荷を与えることができる重量靴に関するものである。   The present invention relates to a heavy boot that can apply a greater load to the lower limbs than usual to the leg muscles during walking.

近年、運動不足による体脂肪の増加防止や体力維持向上のため、重たい靴を用いて歩行、走行などの運動を行い下半身に負荷を与え足の筋肉強化やエネルギー消費増加による減量効果を図ることが提案されている。例えば、従来の重量靴の靴底として、弾力性を有するアウトソール及びこの上方に配されたカップインソールから構成され、前記アウトソールの上面に１つの凹部が爪先から踵部にかけた長手方向に前記アウトソールの輪郭に相似するように形成され、前記凹部に弾性材料に金属粉粒を混合した１つの重りを埋設された靴底が特開２００２−１２５７０８号公報で開示されている。また、重量部材を備えた靴においては、靴底又は中敷に重量部材を着脱することにより、全体重量又は重量バランスが調節されるようにした靴が特開２０００−３１２６０２号公報に開示されている。   In recent years, in order to prevent increase in body fat due to lack of exercise and improve physical fitness, it is possible to reduce weight by strengthening leg muscles and increasing energy consumption by applying exercise such as walking and running with heavy shoes to load the lower body Proposed. For example, as a sole of a conventional heavy shoe, it is composed of a resilient outsole and a cup insole disposed above the sole, and one recess is formed on the upper surface of the outsole in the longitudinal direction from the toe to the heel. Japanese Patent Application Laid-Open No. 2002-125708 discloses a shoe sole formed so as to resemble the outline of an outsole and having one weight embedded in an elastic material mixed with metal powder particles in the recess. Also, in a shoe equipped with a weight member, Japanese Patent Application Laid-Open No. 2000-31602 discloses a shoe whose overall weight or weight balance is adjusted by attaching or detaching the weight member to or from the sole or insole. Yes.

しかしながら、前者の重量靴の靴底に埋設された重りは爪先側が薄く踵部は厚くなるような形状であるため靴の重心が踵部よりになり、歩行中に踵部が下がって踵抜けが発生したりして歩行しづらいものであった。またその重りを成形するにはサイズ毎に成形型を準備しなければならず製造コストが増加し、またその重量靴は全体重量が当初から通常の３〜４倍重く設定され、しかも靴完成後では重りの着脱ができない構造であるため、装着者の体格にあわず足や膝を痛める原因となっていた。   However, since the weight embedded in the sole of the former heavy shoe is shaped so that the toe side is thin and the heel part is thick, the center of gravity of the shoe becomes more than the heel part, and the heel part lowers during walking, so It occurred and was difficult to walk. In addition, in order to mold the weight, a mold must be prepared for each size, which increases the manufacturing cost, and the weight of the heavy shoe is set to be 3 to 4 times the normal weight from the beginning. However, because it is a structure in which the weight cannot be attached / detached, it causes damage to the legs and knees regardless of the physique of the wearer.

一方、後者の重量靴は重りを着脱し、靴の全体重量又は重量バランスが調整できるように構成されているが、靴底側面に多数貫通した重りの装着孔が形成され、また重量を重く設定するにはそれだけ装着する靴底の装着孔の径も大きくなり、それに伴って通常の靴底よりも厚くなる。よって、重量靴は重りが多数であるため重量バランスを設定することが難しく、また靴底に装着した重り又は装着孔が外部から見えるため違和感があり外観が好ましいものでなく満足できるものではなかった。そしてその靴の全体重量は単にウォーキング用には片足の重量が４００ｇ〜８００ｇ程度で単に想定されており、特に体格の小さい者(体重が軽い人)にとっては上記と同様に前記重りは重量過剰となり足を痛める原因となり、一方体格が大きい人(体重が重たい人)にとっては重りが重量過小となり長い期間トレーニングしても効果が効果的に得られず、全体重量に関して装着者の体格は全く考慮されていなかった。
特開２００２−１２５７０８号公報 特開２０００−３１２６０２号公報 On the other hand, the latter weight shoes are configured so that the weight can be removed and the overall weight or weight balance of the shoes can be adjusted, but there are many weight mounting holes formed on the side of the shoe sole, and the weight is set to be heavy. In order to do so, the diameter of the mounting hole of the shoe sole to be mounted is increased accordingly, and accordingly, it is thicker than a normal shoe sole. Therefore, it is difficult to set the weight balance because there are many weights for heavy shoes, and the weight attached to the shoe sole or the mounting hole is visible from the outside, so the appearance is unsatisfactory and not satisfactory. . And the overall weight of the shoe is simply assumed for walking, with the weight of one leg being around 400g-800g, especially for those with a small physique (those with a light weight), the weight will be overweight as above. For people with large physique (heavy weight), the weight is underweight and training is not effective even for a long period of time, and the physique of the wearer is completely considered with respect to the total weight. It wasn't.

解決しようとする問題点は、従来の欠点を解消し装着者の体格を考慮したもので、片足の靴の全体重量の初期設定を最小重量にして適切なトレーニング効果を上げるとともにその後体力増強に応じて全体重量を重く設定変更でき、しかも重りを靴内部に収納して外部から見えないようし外観を良好するとともに、重量バランスの調整を容易にし、爪先部に屈曲性を有させ歩き易い重量靴を提供するものである。   The problem to be solved is to solve the conventional drawbacks and take into account the wearer's physique, to improve the appropriate training effect while reducing the initial setting of the total weight of one foot shoe to the minimum weight, and then responding to the physical strength increase Heavy weight shoes that can be set with a heavy overall weight and that the weight is housed inside the shoe so that it cannot be seen from the outside, the appearance is good, the weight balance is easily adjusted, the toe part is flexible, and it is easy to walk Is to provide.

本発明は、重量調整部材を２箇所備えた重量靴において、片足の最小重量を装着者の体重の０．６％以上とし、第１の重量調整部材を靴底の踵部内に埋設すると共に、第２の重量調整部材は外形形状が同一で比重が夫々異なるものとし、靴底と中敷の間に着脱交換によって全体重量を調節可能とした重量靴を要旨とする。本発明の重量靴について最小重量を装着者の体重の０．６％以上に設定することは、鋭意研究の結果、週当たり１４０分以上２０週継続した歩行実験を行い図３に示すように大腰筋の増加がみられ、効果が得られることが判明した。また片足の重量靴は、最大重量を体重の３％以下と設定することが好ましい。これらの重量靴の重量設定は、重量靴の重量が体重の０．６％未満であれば大腰筋増加の効果はみられず、また重量靴の最大重量を体重の３％以上とすると足や膝に負荷が掛かりすぎ痛みを生じる虞があるからである。   The present invention, in a heavy shoe provided with two weight adjustment members, the minimum weight of one foot is 0.6% or more of the weight of the wearer, and the first weight adjustment member is embedded in the heel of the shoe sole, The second weight adjustment member has the same outer shape and different specific gravity, and the gist of the second weight adjustment member is that the overall weight can be adjusted by attaching and detaching replacement between the shoe sole and the insole. Setting the minimum weight of the heavy shoe of the present invention to 0.6% or more of the wearer's body weight is a result of intensive studies, as shown in FIG. An increase in the psoas muscle was seen, and it was found that an effect was obtained. Moreover, it is preferable to set the maximum weight of one foot heavy shoe to 3% or less of the body weight. The weight setting of these heavy shoes shows no effect of increasing psoas muscle if the weight of the heavy shoes is less than 0.6% of the body weight. This is because there is a risk of overloading the knees and causing pain.

また前記第２の重量調整部材は平面形状を足形とし厚みを一定にすると共にゴムと金属粉との混合物で構成し可撓部材としたことを要旨とする。金属粉としては鉄、鉛、ステンレスなどが使用できるが、コスト面から鉄が好ましい。これにより、本発明は靴の中に入れて装着しても屈曲するので歩行動作をスムーズに行うことができる。また第２の重量調整部材は平板状にしたためロール成形できるので成形型が必要なく、多量生産でき、製造コストを低く抑えることができる。第２の重量調整部材は前記金属粉を天然ゴム、合成ゴムなどに配合しロールでシート状に生地出しして、足形に裁断して成形される。また第２の重量調整部材はサイズ毎に外形を同一形状し、前記混合物の配合比により比重を夫々変えて１００ｇ〜２００ｇ重量差のものを複数個準備しておき、必要に応じて着脱交換し、重量靴の全体重量を変更することができる。   The gist of the second weight adjusting member is that it is a flexible member made of a mixture of rubber and metal powder while having a flat foot shape and a constant thickness. As the metal powder, iron, lead, stainless steel and the like can be used, but iron is preferable from the viewpoint of cost. Thereby, since this invention bends even if it puts in a shoe | wear and wears, it can perform a walk operation | movement smoothly. Further, since the second weight adjusting member is formed in a flat plate shape and can be roll-molded, a molding die is not required, mass production can be performed, and manufacturing cost can be kept low. The second weight adjusting member is formed by blending the metal powder into natural rubber, synthetic rubber or the like, making a dough into a sheet shape with a roll, and cutting it into a foot shape. In addition, the second weight adjusting member has the same outer shape for each size, prepares a plurality of ones having a weight difference of 100 g to 200 g by changing the specific gravity according to the blending ratio of the mixture, and is attached and detached as necessary. The overall weight of the heavy shoe can be changed.

さらに前記第１の重量調整部材と第２の重量調整部材との重量バランスにより靴の重心を足の第１中足骨の母指球と踵骨の最下点と中間付近に設定したことを要旨とする。本発明の重量靴は靴底の踵部に第１の重量調整部材を埋設したことで靴の重心が靴底中央付近から踵方向に移動するが、第２の重量調整部材が図２及び図５に示すように爪先部が幅広く踵部は狭い板状の足形であるので、その重心（ｇ）は本体部材の中心（ｆ）から少し爪先よりに位置されているので、これを靴底と中敷の間に配設することにより、前記靴底の踵部に第１の重量調整部材を埋設した靴の重心（ｅ）を爪先方向に戻して移動させ足の第１中足骨（ｂ）の母指球（ｃ）と踵骨（ｄ）の最下点との中間付近に調整設定することができる。従って、本発明の重量靴は靴の重心を足の骨格構造のおける縦アーチの中央部に合致させ、具体的にはその位置は足の舟状骨(ａ)に相当し、爪先部と踵部とに均等に全体重量を分散することができ、疲労感が少なく歩行又は走行がスムーズに行える。   Furthermore, the center of gravity of the shoe is set at the middle point of the first metatarsal bone of the foot, the lowest point of the rib, and the middle by the weight balance of the first weight adjusting member and the second weight adjusting member. The gist. In the heavy shoe of the present invention, the center of gravity of the shoe moves in the heel direction from the vicinity of the center of the shoe sole by embedding the first weight adjusting member in the heel portion of the shoe sole, and the second weight adjusting member is shown in FIGS. 5, since the toe portion is wide and the heel portion is a plate-like foot shape, the center of gravity (g) is located slightly from the center (f) of the main body member to the toe. By disposing between the insole, the center of gravity (e) of the shoe in which the first weight adjusting member is embedded in the heel portion of the shoe sole is moved back toward the toe to move the first metatarsal (b ) In the middle of the thumb ball (c) and the lowest point of the rib (d). Therefore, the heavy shoe of the present invention matches the center of gravity of the shoe with the center of the longitudinal arch in the skeleton structure of the foot, specifically, the position corresponds to the scaphoid bone (a) of the foot, and the toe portion and the heel The entire weight can be evenly distributed to the part, and there is little feeling of fatigue and walking or running can be performed smoothly.

本発明の重量靴は重量調整部材が靴底の踵部に埋設した第１の重量調整部材と靴底と中敷の間の配設した第２の重量調整部材で構成し、片足の重量靴の最小重量を装着者の体重の０．６％以上とし最小重量の初期設定でトレーニング効果、例えば大腰筋や大殿筋の増強強化が図られるとともに、体脂肪の増加が防止される。また本発明の重量靴は重量調整部材を外部から見えず、しかも重量靴の全体重量を上記２箇所に分散した構造であるので通常の靴と変わらず靴底の厚みを薄くでき外観が良好となる。さらに、本発明の重量靴は靴底本体に重量調整部材が踵部のみに埋設され爪先部には埋設されていない構造であるので爪先部は屈曲性を有し、また靴の重心は第２の重量調整部材の着脱交換で足の第１中足骨の母指球と踵骨の最下点と中間付近に設定調整できる。そして、重量靴は全体重量を爪先部と踵部とに均等に分散できるので、多少重たく設定しても踵抜けがなく歩行し易く足や膝を痛めることがない。   The weight shoe of the present invention comprises a first weight adjustment member in which the weight adjustment member is embedded in the heel portion of the shoe sole, and a second weight adjustment member disposed between the shoe sole and the insole. The minimum weight of the wearer is set to 0.6% or more of the body weight of the wearer, and training effects such as strengthening and strengthening of the psoas muscle and gluteus musculosa are achieved by the initial setting of the minimum weight, and an increase in body fat is prevented. The weight shoe of the present invention has a structure in which the weight adjusting member is not visible from the outside and the weight of the weight shoe is dispersed in the above two locations, so that the thickness of the shoe sole can be reduced and the appearance is good as with ordinary shoes. Become. Furthermore, since the weight shoe of the present invention has a structure in which the weight adjusting member is embedded only in the heel part and not in the toe part in the sole body, the toe part has flexibility, and the center of gravity of the shoe is the second. The weight adjustment member can be set and adjusted near the middle point and the lowest point of the thumb ball and rib of the first metatarsal of the foot. And since heavy shoes can disperse | distribute the whole weight equally to a toe | tip part and a heel part, even if it sets a little heavy, it is easy to walk without slipping out and does not hurt a leg | foot and a knee.

本発明の重量靴は装着者の体格に対応して下肢強化や体脂肪増加防止という目的を、初期設定を最小重量で足に最適な負荷をかけ、その後体力増強に応じて重量を増加し負荷を選定できるようにした。また重量調整部材を外部から見えなくするとともに靴底内部と外部との２箇所に分散して重量バランスを容易に調整できるようにした。   The weight shoe of the present invention has the purpose of strengthening the lower limbs and preventing body fat increase according to the physique of the wearer, applying the optimal load to the foot with the initial setting with the minimum weight, then increasing the weight according to the physical strength increase and the load Can be selected. In addition, the weight adjustment member is made invisible from the outside and dispersed in two locations, the inside and outside of the shoe sole, so that the weight balance can be easily adjusted.

FIG. 2 is a perspective view of the second weight adjusting member, and FIG. 3 is a diagram showing the correlation between the shoe weight per body weight and the rate of change of the psoas muscle. FIG. 4 is a correlation diagram showing the relationship between body weight and shoe size, and FIG. 5 shows a state in which the center of gravity of the weight shoe of the present invention is matched to the skeleton structure of the foot and the total weight is evenly distributed on the toe and heel. It is explanatory drawing shown.

本発明の実施例の重量靴1は、胛被２と、その底面に備えた靴底３とから構成される。胛被２は、皮革、合皮などの素材からなり履口前方には切欠きを設けて緊締部を形成し、そこに鳩目を設け紐が通されている。靴紐は靴重量で伸びが発生しない素材が好ましい。そして、緊締部の内側には通常より厚い低反発スポンジ素材、ゲル素材を用いた舌片６を設けておくと足の甲にかかる衝撃を和らげ足を痛めることがない。
胛被２の素材は縫製箇所が重りで傷むことから引張強度が大きい縫い糸で縫製されることが好ましい。また靴の爪先部には歩行中の衝撃力を緩和するために合成樹脂製又は金属製の爪先補強片を設けることが好ましい。また履口部７の内側には通常より厚いスポンジを介在すれば足首が保護され踵抜けがさらに防止される。 A heavy shoe 1 according to an embodiment of the present invention includes a hood 2 and a shoe sole 3 provided on the bottom surface thereof. The hood 2 is made of a material such as leather or synthetic leather, and is provided with a notch in front of the mouth to form a tightening portion. The shoelace is preferably made of a material that does not generate elongation due to the shoe weight. If a tongue piece 6 made of a low-rebound sponge material or gel material thicker than usual is provided inside the tightening portion, the impact on the instep is softened and the foot is not damaged.
The material of the collar 2 is preferably sewn with a sewing thread having a high tensile strength because the sewing site is damaged by the weight. Moreover, it is preferable to provide a toe reinforcement piece made of synthetic resin or metal in the toe portion of the shoe in order to reduce the impact force during walking. Further, if a thicker sponge than usual is interposed inside the cuff part 7, the ankle is protected and the heel-off is further prevented.

また、重量調整部材は２つの第１の重量調整部材４と第２の重量調整部材５とからなり、第１の重量調整部材４は靴底３の踵部に埋設され、金属、ゴム、合成樹脂などの重たい素材を使用できるが、後述する第２の重量調整部材と同一素材でもよい。第２の重量調整部材５は天然ゴムや合成ゴムに鉄粉配合しロールで厚み５ｍｍのゴムシート状に生地出した後足形に裁断し加硫して成形する。また比重を異にした第２の重量調整部材５は、ゴムに対して鉄粉の配合率を変えて成形され、例えば１５０ｇ、３００ｇ、４５０ｇの重量差１５０ｇの３種類の重りを作成し、重さが異なるものを準備する。   The weight adjusting member includes two first weight adjusting members 4 and a second weight adjusting member 5. The first weight adjusting member 4 is embedded in the heel portion of the shoe sole 3, and is made of metal, rubber, synthetic material. A heavy material such as resin can be used, but it may be the same material as a second weight adjusting member described later. The second weight adjusting member 5 is formed by blending iron powder into natural rubber or synthetic rubber, cutting it into a rubber sheet having a thickness of 5 mm with a roll, cutting it into a foot shape, and vulcanizing it. The second weight adjusting member 5 having a different specific gravity is formed by changing the mixing ratio of the iron powder to the rubber. For example, three types of weights of 150 g, 300 g, and 450 g with a weight difference of 150 g are created, and the weight is adjusted. Prepare something different.

そして靴底３には胛被の踵下面部に例えば１００ｇの第１の重量調整部材４を両面接着テープで装着し、その後胛被の下部の靴底成形空隙に熱可塑性ウレタン素材を射出成形して第１の重量調整部材を埋設した靴を成形する。またこの他の成形法として、前記靴底３はゴムや合成樹脂で成形したユニットソールの踵部に第１の重量調整部材を埋設し、その後胛被と接着して靴を成形してもよい。   For example, 100 g of the first weight adjusting member 4 is attached to the shoe sole 3 with a double-sided adhesive tape on the shoe lower surface portion, and then a thermoplastic urethane material is injection-molded into the shoe sole molding gap at the lower portion of the shoe jacket. Then, a shoe in which the first weight adjusting member is embedded is formed. As another molding method, the shoe sole 3 may be formed by embedding a first weight adjusting member in a heel portion of a unit sole formed of rubber or synthetic resin, and then bonding the heel to the heel to mold the shoe. .

片足の重量靴の全体重量は図４に示すように体重と靴サイズとの相関表より、例えば靴サイズを２３．５ｃｍとすれば、体格に相関する体重を５５ｋｇと推定されその体重の０．６％の３３０ｇとなるように第１の重量調整部材を埋設した重量靴を成形し、これに第２の重量調整部材の代わりに同一厚みの同一形状した軽量スポンジ中底(重さ２０ｇ)を配設して初期設定の重量靴の最小重量を３５０ｇにした。   As shown in FIG. 4, for example, if the shoe size is 23.5 cm, the weight of one foot is estimated as 55 kg, and the weight of the shoe is 0. A heavy shoe with a first weight adjusting member embedded therein is formed so as to be 6% of 330 g, and a lightweight sponge insole (weight 20 g) having the same thickness and the same shape is formed instead of the second weight adjusting member. The minimum weight of the default weight shoe was set to 350 g.

そして、前記軽量スポンジ中底を配設した３５０ｇの重量靴は、必要に応じて上記軽量スポンジ中底を取り出し、該軽量スポンジ中底と前記１５０ｇ、３００ｇ、４５０ｇの重量差１５０ｇの３種類の重りの第２の重量調整部材と夫々交換することにより重量靴の全体重量を５００ｇ、６５０ｇ、７５０ｇへと段階的に変更し重量設定することができる。次に、重量設定した重量靴は、履口から第２の重量調整部材４を靴の中に挿入した後、中敷８をセットして本発明の重量靴１を完成させる。   The 350 g heavy shoe with the lightweight sponge insole is taken out of the lightweight sponge insole as necessary, and the three weights of the lightweight sponge insole and the 150 g, 300 g, and 450 g weight difference 150 g. By replacing each of the second weight adjusting members, the total weight of the heavy shoes can be changed stepwise to 500 g, 650 g, and 750 g and set. Next, in the heavy shoe whose weight is set, the second weight adjusting member 4 is inserted into the shoe through the mouth, and then the insole 8 is set to complete the heavy shoe 1 of the present invention.

完成した重量靴1は、当初踵に埋設された第１の重量調整部材４により靴の重心が中心から踵よりなるが、次に第２の重量調整部材５を靴内にセットすることで、靴の重心が爪先前方へ移動しほぼ足の第１中足骨の母指と踵骨の最下点と中間付近に容易に設定でき、これにより重量バランスがとれた状態での歩行又は走行ができ、しかも全体重量を均等に爪先部と踵部に分散できるので、歩き易い効果が得られる。また、本発明の重量靴は第２の重量調整材が同一厚みなので交換しても足との隙間が変わることがなく、履用感が一定に保たれる。   The completed weight shoe 1 has the center of gravity of the shoe from the center by the first weight adjusting member 4 initially embedded in the bag. Next, by setting the second weight adjusting member 5 in the shoe, The center of gravity of the shoes moves to the front of the toes and can easily be set to the middle point of the first metatarsal bone of the foot and the lowest point and middle of the ribs, so that walking or running in a balanced state is possible. In addition, since the entire weight can be evenly distributed to the toe portion and the heel portion, the effect of being easy to walk is obtained. In addition, since the second weight adjusting material has the same thickness in the heavy shoe of the present invention, the gap with the foot does not change even if the second weight adjusting material is replaced, and the feeling of wearing is kept constant.

さらに、本発明は装着者の体力増強により順次重たい第２の重量調整部材と交換し体力増強に応じて全体重量を設定できる。また本発明の重量靴は第１の重量調整部材が靴底本体踵部のみで爪先部には埋設されてなく、しかも靴底上面に可撓性の第２の重量付加靴を配置した構造であるので靴底の爪先部が屈曲できスムーズな歩行又は走行が行なえる。そして、本発明の重量靴は第１の重量調整部材が靴底踵部に埋設されているので踵部が補強され着地での安定性が向上する。   Further, according to the present invention, the overall weight can be set in accordance with the increase in physical strength by replacing the second weight adjusting member that is heavier with the increase in the physical strength of the wearer. Further, the heavy shoe of the present invention has a structure in which the first weight adjusting member is only the sole body heel portion and is not embedded in the toe portion, and a flexible second weight-added shoe is disposed on the upper surface of the shoe sole. As a result, the toe portion of the shoe sole can be bent and smooth walking or running can be performed. And since the 1st weight adjustment member is embed | buried under the shoe sole heel part in the heavy shoe of this invention, a heel part is reinforced and stability in landing improves.
