Abstract

本発明は、一体型の中足骨部起伏部を有し、甲が被覆中敷および本底外皮に接続されている履物に関する。本発明によれば、上記本底外皮には、２つの成形物が互いに重なり合って配置されており、上記本底外皮における下に配置されている成形物は、上に配置されている成形物および上記本底外皮よりも硬く、上記上に配置されている成形物は、上記本底外皮よりも柔らかいことを特徴とする。  The present invention relates to footwear having an integral metatarsal undulation and the upper is connected to a covering insole and outsole skin. According to the present invention, two molded products are arranged to overlap each other on the outsole skin, and the molded product arranged below the outsole skin is composed of the molded product arranged above and It is characterized by being harder than the outsole skin and being softer than the outsole skin.

Description

本発明は、一体型の中足骨部起伏部を有する履物に関するものである。   The present invention relates to footwear having an integral metatarsal undulation.

人間の足は生きていくうちに極度の負荷にさらされていることが知られている。誤った履物や太りすぎ、スポーツ活動による過負荷などの要因がさらに加われば、多くの場合、距関節やアキレス腱、中足骨部全体の故障につながる可能性がある。   It is known that human feet are exposed to extreme loads during their lives. Additional factors such as wrong footwear, overweight, and overload from sports activities can often lead to failure of the tal joint, Achilles tendon, and the entire metatarsal.

距関節は、足と脚との間をつなぐ要素であって、膝関節のように体の全負荷がかかっている。年齢や太りすぎ、スポーツなどの上述の高い負荷により、軟骨磨耗や頻繁に語られる関節症になることは珍しくない。これらは、自然な運動経過および進行過程を妨げる。   The talc joint is an element that connects the foot and the leg, and a full body load is applied like the knee joint. It is not uncommon to experience cartilage wear and frequent arthropathy due to the above-mentioned high loads such as age, overweight and sports. These hinder the natural course of movement and progression.

腓腹筋の延長部に準じ、踵骨に筋張って付いているアキレス腱も、既に通常の負荷において強く伸長される。そのため、確かにアキレス腱は体の最も強い腱とされてはいるが、残念ながら、一部ではヒールの高すぎる靴を長年にわたって履いていることや、それに起因して一歩毎に繰り返し腱が不意に伸長および収縮するせいで、痛みの無い歩行をほぼ不可能にしてしまう炎症が起こる。   According to the extension of the gastrocnemius, the Achilles tendon attached to the ribs is already strongly stretched under normal load. For this reason, the Achilles tendon is certainly the strongest tendon in the body, but unfortunately, some have worn shoes with too high heels for many years, and as a result, the tendon was suddenly repeated at every step. Stretching and contracting causes inflammation that makes it almost impossible to walk without pain.

しかしながら、高いヒールのものを履くことだけではなく、数年にわたって硬い平坦な床の上を歩いたり立ったりすることも、長い間には足に損害を与えることとなる。   However, walking and standing on a hard flat floor for years, as well as wearing high heels, will damage your feet for a long time.

例えば、柔らかい床の上を素足で歩く場合は当然アーチ支持が無くなるので、時間が経つと縦および横のアーチが沈む。横のアーチが強く沈む場合は、開張足となる。中足骨部小頭が沈み、そして、完全に開いたままとなる。この場合も、歩行の際に痛みのない進行ができなくなる。   For example, when walking on a soft floor with bare feet, naturally the arch support is lost, and as time passes, the vertical and horizontal arches sink. If the horizontal arch sinks strongly, it will be an open leg. The metatarsal head is sunk and remains fully open. Also in this case, it becomes impossible to progress without pain during walking.

上記全ての故障は、歩行や走行の際の進行過程を制限するものなので、整形外科学靴製造者は、このような場合に、大抵は中足骨部領域における靴底の裏側に器材を置く。遷移部は、靴の先および踵に対して平らにされており、一種の起伏部が生じる。この起伏部の頂点は、通常、足根の３つの楔状骨の下にある。いわゆる中足骨部起伏部は、安定して滑らかに進行するように履く人を補助する。中足骨部起伏部は、足根関節の働きを軽減する。また、上部距関節の痛みが和らぎ、アキレス腱の伸長変化が減衰される。   All of the above failures limit the progression process during walking and running, so orthopedic shoe manufacturers often place equipment behind the sole in the metatarsal region, in such cases. . The transition is flattened against the shoe tip and heel, creating a kind of undulation. The peak of this undulation is usually below the three wedge bones of the tarsal. The so-called metatarsal undulations assist a person wearing it so that it travels stably and smoothly. The metatarsal undulations reduce the function of the tarsal joint. It also relieves pain at the upper tal joint and attenuates the Achilles tendon extension.

残念ながら、本底下側に器材を置くと、靴がどうしても整形外科学的で不恰好な外観となってしまう。商品展開に中足骨部起伏部を有するモデルを入れている従来の履き心地の良い靴の製造者でも、靴底は、以前として典型的な風船のような又はシーソーのような外観を有している。   Unfortunately, placing the equipment under the outsole inevitably makes the shoe look orthopedic and unsightly. Even in the case of conventional comfortable shoe manufacturers who have put a model with metatarsal undulations in product development, the soles have a typical balloon-like or seesaw-like appearance as before. ing.

特許文献１に、通常よりもひときわ際立った起伏部が形成されている履物が記載されている。これによれば、足は意識的に不安定化される。その目的は、運動軸のすぐ近くにある全ての筋肉の強化である。つまり、外観は同様に下位的なものであり、治療効果を伴うトレーニング装置である。   Patent Document 1 describes footwear in which undulations that are more conspicuous than usual are formed. According to this, the foot is consciously destabilized. Its purpose is to strengthen all muscles in the immediate vicinity of the motor axis. In other words, the appearance is a lower level device, and is a training device with a therapeutic effect.

一体型の柔らかい敷物又は土台を含むその他多くの靴底又は靴が知られている。靴底に入れられた発泡体や靴の中にある取り外し可能な足の底敷は、踵部および足の前部領域の衝撃を緩和し、足関節を支持する。確かに、多くのこのような靴は、流行上の観点から設計されてはいるが、中足骨部起伏部が緩和をもたらすであろうという上記臨床像の需要を考慮に入れていない。
国際公開第０１１５５６０号Ａ１パンフレット Many other soles or shoes are known, including an integral soft rug or foundation. A foam placed in the sole or a removable foot sole in the shoe mitigates the impact on the buttocks and the front region of the foot and supports the ankle joint. Indeed, many such shoes, although designed from a fashion perspective, do not take into account the above clinical picture demand that metatarsal undulations will provide relief.
International Publication No. 0115560 A1 Brochure

本発明の目的は、距関節、中足骨部領域又はアキレス腱の故障の際に、履く人の需要を考慮し、同時に、特に本底外観を自由に設計できるようにするため、従来のように中足骨部起伏部を外側から本底に形成しなくてよい履物を提供することである。   The purpose of the present invention is to take into account the demand of the wearer in the event of a failure of the talus joint, metatarsal region or Achilles tendon, and at the same time, in particular, in order to be able to freely design the outsole appearance, It is an object of the present invention to provide footwear that does not require a metatarsal undulation to be formed on the bottom from the outside.

上記目的は、特許請求項１の特徴を有する一体型の中足骨部起伏部を有する履物により達成される。   The object is achieved by footwear having an integral metatarsal undulation having the features of claim 1.

上記履物は、履物の底外皮に、好ましくはポリウレタン（ＰＵ発泡体）又は異なる硬度に調整される他の緩衝材からなる２つの成形物がはめ込まれており、互いに重ねて配置されていることを特徴とする。この場合、底外皮は、甲革と柔らかい中敷とからなる甲構造に従来の方法で接続されている。   The above footwear is fitted with two moldings, preferably made of polyurethane (PU foam) or other cushioning material adjusted to different hardness, placed on the bottom skin of the footwear and placed on top of each other Features. In this case, the bottom skin is connected in a conventional manner to an upper structure consisting of an upper and a soft insole.

特別なデザインと、挿入部分の配置および硬さ調整と、底外皮の硬さ調整とは、甲構造と連動して、歩行の際に、底に外部から取り付けられる中足骨部起伏部に匹敵する効果を生じる。   The special design, placement and hardness adjustment of the insertion part, and the hardness adjustment of the bottom skin are comparable to the undulations of the metatarsal bone part that is attached to the bottom from the outside during walking in conjunction with the upper structure. Produces the effect.

本発明の好ましい実施形態は、主請求項に続く下位請求項から明らかとなる。   Preferred embodiments of the invention will become apparent from the subclaims following the main claim.

本発明の更なる特徴、詳細および利点は、図に示す実施形態から明らかとなる。   Further features, details and advantages of the invention will become apparent from the embodiments shown in the figures.

図１に示すように、一体型の中足骨部起伏部を有する本発明の履物（以下、履物と呼ぶ）は、中敷２に接続されている甲革１と、本底外皮５に重ねて置かれてはめ込まれている２つの成形物３，４とからなる。   As shown in FIG. 1, the footwear of the present invention (hereinafter referred to as footwear) having an integral metatarsal portion undulation is superimposed on an upper 1 connected to an insole 2 and a bottom outer skin 5. It consists of two moldings 3 and 4 which are placed and fitted.

甲革１および中敷２は、柔らかい皮革又は合成素材からなることが好ましく、図１に示すように、ジグザグ縫い、直線縫い又は接着によって甲構造となるよう、従来どおりに互いに接続されている。   The upper 1 and the insole 2 are preferably made of soft leather or synthetic material, and are connected to each other in a conventional manner so as to form an upper structure by zigzag stitching, straight stitching, or adhesion as shown in FIG.

本底外皮５は、同じく接着又は縫い合わせによって、甲構造１，２と従来どおりに互いに接続されている。   The bottom outer skin 5 is connected to the upper and lower structures 1 and 2 in the same manner as in the past by adhesion or stitching.

成形物４，３および本底外皮５は、ＰＵＲ発泡体又は異なる硬度に調整される他の緩衝材からなることが好ましい。図２に示すように、本底外皮５において上側に配置されている成形物３は、約１０〜１２ｍｍの周縁に平坦にはめ込まれている。   The moldings 4 and 3 and the bottom shell 5 are preferably made of PUR foam or other cushioning material adjusted to a different hardness. As shown in FIG. 2, the molded product 3 arranged on the upper side of the bottom outer skin 5 is fitted flat on the periphery of about 10 to 12 mm.

図３および図４に、成形物３が足の前部領域５Ａの一断面および足の後部領域５Ｃの断面においてどのようにはめ込まれているかを断面図で示す。成形物３の高さは、足の前部領域５Ａにおいて少なくとも６ｍｍであることが好ましく，足の後部領域５Ｃにおいて少なくとも８ｍｍであることが好ましい。図５に示すように、成形物３は、中足骨部領域５Ｂにおいては成形物４の上に配置されている。成形物３は、成形物４の頂点上において、約４〜６ｍｍの高さである。   FIGS. 3 and 4 are sectional views showing how the molded product 3 is fitted in one cross section of the front region 5A of the foot and the cross section of the rear region 5C of the foot. The height of the molded product 3 is preferably at least 6 mm in the front region 5A of the foot, and preferably at least 8 mm in the rear region 5C of the foot. As shown in FIG. 5, the molded product 3 is disposed on the molded product 4 in the metatarsal region 5B. The molded product 3 has a height of about 4 to 6 mm on the apex of the molded product 4.

しかしながら、基本的に、成形物３の高さは、履く人の特別な需要に合わせることができる。この場合、例えば履く人の体重を考慮することができる。   However, basically, the height of the molding 3 can be adapted to the special demands of the wearer. In this case, for example, the weight of the wearer can be considered.

図５および図７に示すように、成形物３の下方の本底外皮５にはめ込まれている成形物４は、前後がくさび形に仕上げられており、足の後部領域５Ｃおよび足の前部領域５Ａの方向に先細りしている。図６に示すように、成形物４は、中足骨部領域５Ｂにおいて、内側の縦アーチ５Ｄに沿って、外側の縦アーチ５Ｅの領域よりも高く形成されている。全体的な高さは、履く人の需要に自由に合わせられていてもよい。   As shown in FIGS. 5 and 7, the molded product 4 fitted into the bottom bottom skin 5 below the molded product 3 has a wedge-shaped finish in the front and rear, and the rear region 5C of the foot and the front part of the foot. Tapering in the direction of region 5A. As shown in FIG. 6, the molded product 4 is formed higher in the metatarsal region 5B than the region of the outer longitudinal arch 5E along the inner longitudinal arch 5D. The overall height may be freely adjusted to the wearer's demand.

成形物３，４および本底外皮５は、異なる硬度に調整されている。本底外皮５において成形物３の下方にはめ込まれている成形物４は、成形物３および本底外皮５よりも硬く、この場合、成形物３は本底外皮５よりも柔らかい。   The moldings 3 and 4 and the outsole skin 5 are adjusted to different hardnesses. The molded product 4 fitted below the molded product 3 in the bottom bottom skin 5 is harder than the molded product 3 and the bottom bottom skin 5. In this case, the molded product 3 is softer than the bottom bottom skin 5.

図５および図６に示すように、成形物３，４は、例えばＰＵＲ発泡体材料の注入後、ＰＵＲ発泡体材料によってしっかりと取り囲まれているように、本底外皮５の形状にはめ込まれている。図２に示すように、本底外皮の平面図においてのみ、上方にはめ込まれた成形物３を見ることができる。   As shown in FIGS. 5 and 6, the moldings 3 and 4 are fitted into the shape of the bottom skin 5 so that, for example, after the injection of the PUR foam material, the moldings 3 and 4 are firmly surrounded by the PUR foam material. Yes. As shown in FIG. 2, the molded product 3 that is fitted upward can be seen only in the plan view of the bottom shell.

中敷２は柔らかいので、歩行又は走行の際に、進行過程の第１段階（図８）において、足は、履物によって本底外皮の足の後部領域５Ｃにおける柔らかい成形物３へ押される。   Since the insole 2 is soft, during walking or running, the foot is pushed by the footwear onto the soft molding 3 in the rear region 5C of the foot of the outsole skin during the first stage of the progression (FIG. 8).

第２段階（図９）において、足は、中足骨部領域５Ｂにおける比較的硬い成形物４上に進行し、第３段階（図１０）において、成形物３の柔らかい足の前部領域５Ａに入る。   In the second stage (FIG. 9), the foot proceeds on the relatively hard molding 4 in the metatarsal region 5B, and in the third stage (FIG. 10) the soft foot front region 5A of the molding 3. to go into.

本底外皮５の平均的な硬さ調整により、全工程は、緩衝されながら支持される。本底外皮の外観は、広く自由に設計することができる。   By adjusting the average hardness of the bottom outer skin 5, the entire process is supported while being buffered. The appearance of the bottom skin can be designed freely and widely.
