Description

本発明は、運動靴などの履物に関し、更に具体的には、運動能力や身体機能の強化ないし改善に好適な履物に関するものである。   The present invention relates to footwear such as athletic shoes, and more specifically to footwear suitable for strengthening or improving athletic ability and physical function.

脚部の筋肉は、人体の中でも最も大きな筋肉の一つであるが、日常生活ではその半分程度しか使われていないといわれている。特に、大腿部の裏側の筋肉や臀部の筋肉は、デスクワークなどが多く運動する機会が少ない人にとっては鍛えにくく衰え易い部分であるため、これらの筋肉を強化したりストレッチしたりすることで身体機能の改善や運動能力の向上が期待できる。例えば、以下に示す特許文献１には、靴底の前方を後方側（踵側）より高くして、靴の内側底面を前方側から後方側に下向きに斜めにすることで、常に踵を地面に接した状態で靴の内側底面と同程度に傾いた坂道を上がるような運動効果を得ることを目的とした靴が開示されている。
特開平９−１６４００２号公報 Leg muscles are one of the largest in the human body, but it is said that only about half of them are used in daily life. In particular, the muscles on the back of the thigh and the buttocks are difficult to train and tend to decline for people who have a lot of deskwork and have few opportunities to exercise, so strengthening and stretching these muscles to strengthen the body Improvement of function and improvement of athletic ability can be expected. For example, in Patent Document 1 shown below, the front of the shoe sole is made higher than the rear side (the heel side), and the inner bottom surface of the shoe is inclined downward from the front side to the rear side, so that the heel is always on the ground. There is disclosed a shoe for the purpose of obtaining a movement effect that climbs up a slope inclined to the same extent as the inner bottom surface of the shoe in contact with the shoe.
JP-A-9-164002

しかしながら、以上のような背景技術では、脚部の裏側の筋肉を鍛える効果を得ることはできるが、身体の他の部分（例えば腹部など）の筋肉の強化やストレッチを行うことはできない。また、正常な歩行を行うためには、通常は、踵，足指の付根，爪先へと順に重心を移動させることが必要とされるが、上述した背景技術では、常に爪先側が高く、踵側が低くなっているため、重心移動をスムーズに行うことができず、素早いフットワークが要求されるスポーツなどに利用するのは困難である。   However, the background art as described above can obtain the effect of training the muscles on the back side of the legs, but cannot strengthen or stretch muscles in other parts of the body (for example, the abdomen). In order to perform normal walking, it is usually necessary to move the center of gravity sequentially to the heel, the base of the toes, and the toes. However, in the background art described above, the toes are always high and the heels are Since it is low, the center of gravity cannot be moved smoothly, and it is difficult to use it for sports that require quick footwork.

本発明は、以上の点に着目したもので、その目的は、脚部を中心とした運動能力の強化・改善を図るとともに、重心の偏りによる身体機能の低下防止に好適な履物を提供することである。   The present invention focuses on the above points, and its purpose is to provide footwear suitable for strengthening and improving athletic ability centered on the legs and preventing deterioration of physical functions due to bias in the center of gravity. It is.

前記目的を達成するため、本発明の履物は、足指の付根側が踵側よりも高い位置となるように履物内側に形成された第１の傾斜面，前記足指の付根側から爪先側へ向けて履物底部に形成された第２の傾斜面，前記付根部分において、親指側が小指側よりも低い位置となるように履物内側に形成された第３の傾斜面，を備えたことを特徴とする。更には、前記履物の底部に、少なくとも一つの機能部品を設けたことを特徴とする。他の発明は、足指の付根側が踵側よりも高い位置となるように履物内側に形成された第１の傾斜面，前記足指の付根側から爪先側へ向けて履物底部に形成された第２の傾斜面，前記履物の底部に設けられた、少なくとも一つの機能部品，を備えたことを特徴とする。更に他の発明は、履物の底部に少なくとも一つの機能部品を備えており、該機能部品が、回転可能な円板，回転可能なボール，スプリング，エッジ，滑走板のいずれかであることを特徴とする。本発明の前記及び他の目的，特徴，利点は、以下の詳細な説明及び添付図面から明瞭になろう。   In order to achieve the above object, the footwear of the present invention has a first inclined surface formed on the inside of the footwear so that the base side of the toe is higher than the heel side, from the base side of the toe to the toe side. A second inclined surface formed on the bottom of the footwear, and a third inclined surface formed on the inner side of the footwear so that the thumb side is positioned lower than the little finger side in the base portion. To do. Furthermore, at least one functional component is provided on the bottom of the footwear. In another invention, the first inclined surface formed on the inside of the footwear so that the base side of the toes is higher than the heel side, formed on the bottom of the footwear from the base side of the toes toward the toe side It is characterized by comprising at least one functional component provided at the second inclined surface, the bottom of the footwear. Still another invention is characterized in that at least one functional component is provided at the bottom of the footwear, and the functional component is any one of a rotatable disc, a rotatable ball, a spring, an edge, and a sliding board. And The above and other objects, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

本発明は、足指の付根側が踵側よりも高い位置となるように内側に形成された第１の傾斜面と、前記足指の付根側から爪先側へ向けて履物底部に形成された第２の傾斜面を備えた履物において、該履物内側に、親指側が小指側よりも低くなるような第３の傾斜面を設けるか、あるいは、前記履物底部に着脱可能な機能部品を設けることとした。このため、姿勢を適切に保ち、運動能力の強化や、重心の偏りによって生じる症状の防止や改善を図ることができる。また、機能部品を第２の傾斜面に設けたときは、踵側から爪先側への重心移動のみで機能部品の使用と中止の切り替えを行うことができるとともに、前記機能部品により、脚部のみなら身体の他の部分の筋肉の強化やストレッチなどを容易に行うことができる。   The present invention provides a first inclined surface formed on the inner side so that the base side of the toes is higher than the heel side, and a first inclined surface formed on the bottom of the footwear from the base side of the toes toward the toe side. In the footwear having two sloping surfaces, a third sloping surface is provided on the inner side of the footwear so that the thumb side is lower than the little finger side, or a functional part that can be attached and detached is provided on the bottom of the footwear. . For this reason, it is possible to maintain posture appropriately, and to prevent or improve symptoms caused by strengthening exercise ability and biasing the center of gravity. Further, when the functional component is provided on the second inclined surface, the functional component can be used and stopped only by moving the center of gravity from the heel side to the toe side, and only the leg portion can be switched by the functional component. So you can easily strengthen or stretch muscles in other parts of the body.

以下、本発明を実施するための最良の形態を、実施例に基づいて詳細に説明する。   Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

最初に、図１〜図３を参照しながら、本発明の実施例１を説明する。図１(A)は、本実施例の構成を示す側面図，図１(B)は前記(A)を矢印Ｆ１方向から見た正面図である。図２及び図３は、本実施例の使用状態を示す図である。これらの図に示すように、本実施例のシューズ１０は、足裏の中心よりやや前寄りの位置，すなわち、足指の付根部分（図１(B)の母子球５２と小子球を結ぶライン）が厚く形成された靴底１２を有している。このため利用者５０の足裏が接するシューズ１０の内底は、図１(A)に示す状態では線ＬＡで示すように接地面４０に対して傾斜している。図示の例では、本発明の理解を容易にするため、接地面４０は水平面となっている。また、シューズ１０の内底は、小指側よりも親指側が低くなるように、すなわち図１(B)の線ＬＢで示すように、接地面４０に対して傾斜が設けられている。更に、靴底１２は、前記付根部分から爪先側１４へ向けて上方に反った傾斜面１８を有している。   First, Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1A is a side view showing the configuration of this embodiment, and FIG. 1B is a front view of (A) seen from the direction of arrow F1. 2 and 3 are diagrams showing a use state of the present embodiment. As shown in these figures, the shoe 10 of the present embodiment is positioned slightly forward from the center of the sole, that is, the base part of the toes (the line connecting the mother-child sphere 52 and the child sphere in FIG. 1B). ) Has a sole 12 formed thick. Therefore, the inner bottom of the shoe 10 with which the sole of the user 50 is in contact is inclined with respect to the ground plane 40 as shown by a line LA in the state shown in FIG. In the illustrated example, the ground plane 40 is a horizontal plane in order to facilitate understanding of the present invention. Further, the inner bottom of the shoe 10 is inclined with respect to the ground plane 40 so that the thumb side is lower than the little finger side, that is, as indicated by a line LB in FIG. Further, the shoe sole 12 has an inclined surface 18 that warps upward from the root portion toward the toe side 14.

前記シューズ１０の靴底材内部には、前後の複数箇所に機能部品を取り付けるための取付金具３０が埋め込まれて固定されている。取付金具３０は、図１(C)に示すように、四角形の平板３０Ａの中央に、機能部品を着脱するための受け軸３０Ｂを立設した構造となっており、この受け軸３０Ｂは靴底１２の窪み部１２Ａに露出している。また、受け軸３０Ｂの軸方向が、概ね靴底面に対して法線方向となるように、取付金具３０が固定されている。例えば図２(A)に示すように、足指の付根部分を接地させた状態のときに、前記受け軸３０Ｂが接地面４０に対して略垂直の方向となるように、取付金具３０が靴底１２に設けられている。   Inside the shoe sole material of the shoe 10, mounting brackets 30 for attaching functional parts to a plurality of front and rear portions are embedded and fixed. As shown in FIG. 1 (C), the mounting bracket 30 has a structure in which a receiving shaft 30B for attaching / detaching a functional component is erected at the center of a rectangular flat plate 30A. The twelve depressions 12A are exposed. Further, the mounting bracket 30 is fixed so that the axial direction of the receiving shaft 30B is substantially normal to the shoe bottom surface. For example, as shown in FIG. 2 (A), the mounting bracket 30 is attached to the shoe so that the receiving shaft 30B is in a direction substantially perpendicular to the ground plane 40 when the base of the toes is grounded. It is provided on the bottom 12.

一方、機能部品の一つである回転アダプタ２０は、図１(D)に拡大して示すように、接地面４０に当接する円板２０Ａが、軸受け機構２０Ｂを介して取付軸２０Ｃに回転可能に接合された構成となっている。取付軸２０Ｃには、取付穴２０Ｄが設けられている。このような回転アダプタ２０は、取付穴２０Ｄに、靴底１２の取付金具３０の受け軸３０Ｂが入り込むことで、回転可能かつ着脱可能に靴底１２に取り付けられる。   On the other hand, in the rotary adapter 20 which is one of the functional parts, as shown in an enlarged view in FIG. 1 (D), the disc 20A that abuts against the ground surface 40 can rotate to the mounting shaft 20C via the bearing mechanism 20B. It is the structure joined to. A mounting hole 20D is provided in the mounting shaft 20C. Such a rotation adapter 20 is attached to the shoe sole 12 so as to be rotatable and detachable by inserting the receiving shaft 30B of the fitting 30 of the shoe sole 12 into the attachment hole 20D.

次に、本実施例の作用を説明する。最初に、図２(A)及び図３を参照して回転アダプタ２０を利用する場合について説明する。まず、回転アダプタ２０の取付軸２０Ｃを、靴底１２の窪み部１２Ａを介して受け軸３０Ｂに装着し、図２(A)に示すように回転アダプタ２０の円板２０Ａの表面を接地面４０に接触させて立つ。このとき、片足で立つと、図３(A)に示すように、通常はμ（ミュー／摩擦抵抗）の低い氷上や、磨いた床等でないと困難な回転運動ないしスピン運動を行うことができる。また、両足で立つと、図３(B)に示すようにツイスト運動を行うことができる。スピン運動を行うことでバランス感覚を養うことができ、ツイスト運動を行うことにより、日常の動作であまり行わない「ひねり」の動作を容易に行うことができる。身体をひねる場合には、主に腹斜筋が使われるが、本実施例のシューズ１０を利用すれば、加齢や運動不足により長年使われなかった腹斜筋を効率よく刺激することができ、腰痛の予防と解消，ウエスト周りの筋肉強化，ウエスト周りの脂肪の減少，便秘の解消などの効果を期待することができる。なお、回転アダプタ２０を使用する場合には、爪先側１４へ重心を移動すればよく、使用しない場合には踵側１６へ重心を移動するか回転アダプタ２０を取り外すようにすればよい。   Next, the operation of this embodiment will be described. Initially, the case where the rotation adapter 20 is utilized is demonstrated with reference to FIG. 2 (A) and FIG. First, the mounting shaft 20C of the rotating adapter 20 is mounted on the receiving shaft 30B via the recess 12A of the shoe sole 12, and the surface of the disk 20A of the rotating adapter 20 is placed on the grounding surface 40 as shown in FIG. Stand in contact with. At this time, when standing on one foot, as shown in FIG. 3 (A), it is usually possible to perform a rotational motion or spin motion that is difficult unless it is on a low μ (mu / friction resistance) ice or a polished floor. . Further, when standing with both feet, a twisting exercise can be performed as shown in FIG. By performing the spin exercise, a sense of balance can be cultivated, and by performing the twist exercise, a “twist” operation that is not often performed in daily operations can be easily performed. When twisting the body, the oblique muscles are mainly used, but if the shoes 10 of this embodiment are used, the oblique muscles that have not been used for many years due to aging or lack of exercise can be stimulated efficiently. It can be expected to prevent and eliminate low back pain, strengthen muscles around the waist, reduce fat around the waist, and eliminate constipation. When the rotary adapter 20 is used, the center of gravity may be moved to the toe side 14, and when not used, the center of gravity may be moved to the heel side 16 or the rotary adapter 20 may be removed.

次に、回転アダプタ２０を利用しない場合について説明する。本実施例のシューズ１０から回転アダプタ２０を取り外して歩行ないし運動する場合、通常の着地状態が図１(A)に相当し、踏み切りへ動作が移る状態が図２(B)に相当する。まず、図１(A)に示す着地して起立した状態においては、踵側１６が低くなっているため、足裏の角度が前上がりになる。足裏の角度が前上がりになると、その状態のままでは後ろに倒れてしまうため、身体のバランスを保つため利用者５０の身体は、自然に前傾する。このように前傾した状態でのふくらはぎの筋肉は、軽く引き延ばされた（ストレッチされた）状態となる。歩行中、着地から踏み切りへ動作が移る際には、図１(B)に示すように足裏の重心が内側加重となるように矯正されるため、踏み切り力の強化を図ることができる。また、図１(B)に線ＬＢで示す傾斜のため、内側重心が保たれるようになり、Ｏ脚やＸ脚，これらが複合したＯＸ脚などの改善や防止を行うことができる。このように、ふくらはぎがある程度ストレッチされた状態で歩行すると、ふくらはぎの筋肉が動作できる範囲に制限を受けるため、代わりに腿の裏側の筋肉（大腿二頭筋）やお尻の筋肉（大殿筋）が作用し、これらの筋肉のストレッチ効果を得ることもできる。また、歩行せずに、足指の付根部分、すなわち、靴底１２の傾斜面１８の下側で立つことにより、母子球及び小子球を結ぶラインでの直立やフットワークの訓練を行うこともできる。   Next, the case where the rotation adapter 20 is not used will be described. When walking or exercising with the rotary adapter 20 removed from the shoe 10 of this embodiment, the normal landing state corresponds to FIG. 1 (A), and the state in which the operation moves to the crossing corresponds to FIG. 2 (B). First, in the state of landing and standing as shown in FIG. 1 (A), since the heel side 16 is lowered, the angle of the sole is raised forward. If the sole angle rises forward, it will fall back in that state, so the body of the user 50 naturally tilts forward to maintain balance of the body. Thus, the calf muscle in the forward tilted state is in a slightly stretched state. When the movement moves from landing to crossing during walking, as shown in FIG. 1B, the center of gravity of the sole is corrected so as to be inwardly weighted, so that the crossing force can be strengthened. In addition, because of the inclination indicated by the line LB in FIG. 1B, the inner center of gravity can be maintained, and the O leg, the X leg, and the OX leg in which these are combined can be improved or prevented. In this way, if you walk with the calf stretched to some extent, the range of calf muscles is limited so that the muscles on the back of the thigh (biceps) and buttocks (gastrocnemius) instead. Can also act to stretch these muscles. Further, by standing on the base part of the toes, that is, on the lower side of the inclined surface 18 of the shoe sole 12 without walking, it is possible to perform upright or footwork training on a line connecting the mother-child ball and the child-ball. .

このように、実施例１によれば、シューズ１０の内面に、足指の付根部分が踵側１６よりも高い位置となる傾斜及び親指側が小指側よりも低くなる傾斜を設け、靴底１２の足指付根部分から爪先側１４に向けては傾斜面１８を設ける。そして、前記靴底１２の足指の付根部分に回転アダプタ２０を着脱可能に設けることとしたので、次のような効果がある。
(1)直立状態での重心を踵側から爪先側へ移動させることができるため、筋肉や運動神経に対して日常とは異なる刺激を与えることができ、筋力の強化や身体の柔軟性の向上し、運動能力や身体機能の強化・改善を図ることができる。また、踵重心で立つことができるため、外反母趾などの予防・改善を図ることができる。
(2)内側重心を保つことができるため、歩行中の重心移動の際の踏み切り力を強化するとともに、偏重心によるＸ脚やＯ脚などの発症の予防・改善を図ることができる。
(3)回転アダプタ２０を利用した回転運動ないしツイスト運動により、脚部以外の身体部分の運動ないしストレッチを行うことができる。
(4)踵側１６から爪先側１４への重心移動のみで回転アダプタ２０の使用とその中止を切り替えることができる。
(5)回転アダプタ２０の軸受け２０を、靴底１２の足指の付根部分に斜めに内蔵固定するため、必要以上に靴底１２が厚くならず、デザイン性を損なうことがない。 As described above, according to the first embodiment, the inner surface of the shoe 10 is provided with an inclination in which the base part of the toe is higher than the heel side 16 and an inclination in which the thumb side is lower than the little finger side. An inclined surface 18 is provided from the toe side toward the toe side 14. And since it decided to provide the rotation adapter 20 in the base part of the toe of the said shoe sole 12 so that attachment or detachment is possible, there exist the following effects.
(1) Since the center of gravity in the upright state can be moved from the heel side to the toe side, muscles and motor nerves can be stimulated differently from everyday, strengthening muscle strength and improving body flexibility It is possible to strengthen and improve athletic ability and physical function. In addition, since it can stand at the center of gravity of the heel, it is possible to prevent and improve hallux valgus and the like.
(2) Since the inner center of gravity can be maintained, it is possible to strengthen the crossing force when moving the center of gravity during walking, and to prevent or improve the onset of X leg or O leg due to the eccentric center of gravity.
(3) By rotating or twisting using the rotation adapter 20, it is possible to exercise or stretch a body part other than the leg.
(4) The use of the rotary adapter 20 and the cancellation thereof can be switched only by moving the center of gravity from the heel side 16 to the toe side 14.
(5) Since the bearing 20 of the rotary adapter 20 is obliquely incorporated and fixed at the base of the toe of the shoe sole 12, the shoe sole 12 is not thicker than necessary, and the design is not impaired.

なお、本発明は、上述した実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることができる。例えば、以下のものも含まれる。

In the example of FIG. 4A, a mounting shaft 102 is provided on a U-shaped spring 100. In the example of FIG. 4B, the mounting shaft 112 is provided on the spiral spring 110. Stop plates 114 and 116 are provided at both ends of the spiral spring 110, and the mounting shaft 112 is provided on the stop plate 116. In the example of FIG. 4C, a ball (sphere) 120 is rotatably held by a joint 122, and a mounting shaft 124 is provided on the top of the joint 122. The example of FIG. 4D is an example in which mounting shafts 132 and 134 are provided on a ski board 130 for glass skiing. In this example, two mounting brackets 30 are necessary on the shoe sole 12 side. Instead of the ski board 130, an edge for skating may be attached.

(3)上述した機能部品は、シューズ１０の左右で異なるものを設けるようにしてもよいし、複数設けるようにしてもよい。更に、取付金具３０の構造や、これに回転アダプタ２０などの機能部品を取り付ける機構も一例であり、同様の効果を奏するように適宜変更してよい。例えば、凹凸が係合する構造とする，ボルト・ナットによる構造とする，磁石を利用するなどである。取付金具３０として磁石を用いると、該磁石による磁気が足に作用するようになり、これによる効果も期待できる。   (3) The functional parts described above may be provided differently on the left and right of the shoe 10, or a plurality of functional parts may be provided. Furthermore, the structure of the mounting bracket 30 and a mechanism for mounting a functional component such as the rotary adapter 20 to this are also examples, and may be appropriately changed so as to achieve the same effect. For example, a structure in which concaves and convexes are engaged, a structure using bolts and nuts, and a magnet are used. When a magnet is used as the mounting bracket 30, the magnetism of the magnet acts on the foot, and the effect of this can be expected.

(4)本発明の履物は、テニスや野球，バスケットボール，バレーボールなどの急激なダッシュやストップを要求されるスポーツや、走り幅跳び，走り高跳びなどの瞬発力が要求されるスポーツ、あるいは、踵重心の養成で力を発揮するゴルフや柔道，ウエイトリフティングなどのスポーツにおける運動能力の強化に好適であるが、スポーツ用に限定されるものではなく日常の履物としても利用可能である。また、ダンスやスケート用の靴として利用するようにしてもよい。   (4) The footwear of the present invention can be used for sports such as tennis, baseball, basketball, and volleyball that require rapid dashing and stopping, sports that require instantaneous power, such as long jump and high jump, or training of the center of gravity. Although it is suitable for strengthening athletic ability in sports such as golf, judo, and weightlifting that demonstrate its power, it is not limited to sports but can also be used as daily footwear. Moreover, you may make it utilize as shoes for dance and skating.

本発明によれば、足指の付根側が踵側よりも高い位置となるように履物内側に形成された第１の傾斜面と、前記足指の付根側から爪先側へ向けて履物底部に形成された第２の傾斜面を備えた履物において、該履物の内側に、親指側が小指側よりも低い位置となるような第３の傾斜面を設けるか、あるいは、前記履物底部の足指の付根部分に着脱可能な機能部品が設けられる。これにより、姿勢を適切に保つとともに、踵側から爪先側への重心移動のみで機能部品の使用と中止の切り替えを行うことができるため、各種スポーツなどに利用される履物として適用できる。特に、靴底に傾斜があるため、機能部品を埋め込んでも靴底が厚くならず外観が損なわれることがなく、デザインが重視される履物としても好適である。   According to the present invention, the first inclined surface formed on the inside of the footwear so that the base side of the toe is higher than the heel side, and formed on the bottom of the footwear from the base side of the toe toward the toe side In the footwear having the second inclined surface, a third inclined surface is provided on the inner side of the footwear so that the thumb side is positioned lower than the little finger side, or the toe root of the footwear bottom is provided. A detachable functional part is provided on the part. Accordingly, the posture can be appropriately maintained, and the use and stop of the functional component can be switched only by the movement of the center of gravity from the heel side to the toe side, so that it can be applied as footwear used in various sports. In particular, since the shoe sole is inclined, even if functional parts are embedded, the shoe sole does not become thick and the appearance is not impaired.
