【発明の詳細な説明】
〈産業上の利用分野〉
本発明は靴に関し、特に履き心地が良く、履口部の形状
も良好な状態が保持できる靴に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to shoes, and particularly to shoes that are comfortable to wear and whose opening portion can maintain a good shape.
〈従来の技術〉
靴は流通過程に於いて、又、消費者が購入後、相当長期
間多数回にわたって履いたり、脱いだりしていると履口
部が横に広がり、いわゆる「笑う」という現象が生し、
靴外観を損なうのみならず、又、履用中、足が靴に密接
せず、歩きにくくなる等の欠点がしばしば見られた。<Prior art> During the distribution process of shoes, and when consumers wear and take them off many times over a considerable period of time after purchasing them, the opening of the shoes expands laterally, causing a phenomenon called "smiling". live,
Not only do they impair the appearance of the shoes, but they also often have drawbacks such as the foot not coming into close contact with the shoe during wear, making it difficult to walk.
従来、このような欠点を除去しようとしてマルテンサイ
ト変態点より高温側が、履用中の温度、又はその温度よ
り高い温度と一致するようなＮｉＴｉ系形状記憶合金よ
りなるＵ字形芯体を履口部に有する靴が提案されていた
。Conventionally, in an attempt to eliminate such defects, a U-shaped core made of a NiTi-based shape memory alloy was used in the shoe opening, so that the temperature higher than the martensitic transformation point matches the temperature during wear or a temperature higher than that temperature. Shoes with the following were proposed.
〈発明が解決しようとする課題〉
前記従来のように履口部にマルテンサイト変態点より高
温側が、履用中の温度又はその温度より高い温度と一致
するようなＮｉＴｉ系形状記憶合金よりなるＵ字形芯体
を使用した靴は、確かに所期の形状が保持され良好な外
観を呈し、又、雇用中足が靴に密着するけれども長時間
履用し続けると、前記Ｕ字形芯体が足に食い込み、足を
傷めついには折れてしまい雇用困難となっていた。<Problems to be Solved by the Invention> As in the prior art, the shoe opening has a U-shape made of a NiTi-based shape memory alloy such that the higher temperature side than the martensitic transformation point corresponds to the temperature during wear or a temperature higher than that temperature. Shoes using a core certainly retain their desired shape and have a good appearance.Also, although the foot is in close contact with the shoe during employment, if the shoe is worn for a long time, the U-shaped core will not touch the foot. It dug in, hurting his leg, and eventually breaking, making it difficult to employ him.
〈課題を解決するための手段〉

形芯体を履口部に有する靴を提供したものである。<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention provides that the temperature at a temperature lower than the martensitic transformation point is -10°C to 40°C, preferably -50°C.
The present invention provides a shoe having a U-shaped core made of a NiTi-based shape memory alloy at a temperature of .degree. C. to 35.degree. C. in the shoe opening.

ＬＺｎ系合金などもあるが、形状回復能、物性等を考慮
すると本発明には使用しにくい。Shape memory alloys include Cu/11Ni alloy, CuA
Although there are LZn-based alloys, they are difficult to use in the present invention when shape recovery ability, physical properties, etc. are taken into consideration.
前記ＮｉＴｉ系記憶合金は、通常はＦｅ、 Ｃｒ。The NiTi-based memory alloy is usually Fe or Cr.
Ｍｎ、Ｃｕ、Ｚｎ、Ｎｂ、Ｍｏ、Ｔａ、Ａｔ等から選ば

加量はＮｉまたはＴｉの含有量に対し３％以下、好まし
くは２％以下でなければならない。It can be replaced with one or more elements selected from Mn, Cu, Zn, Nb, Mo, Ta, At, etc., but since these lower the martensitic transformation point, the amount added should be smaller than that of Ni or Ti. The content should be less than 3%, preferably less than 2%.
〈作 用〉
靴の履口部に使用されるＮｉＴｉ系形状記憶合金よりな

くは一５℃〜３５℃においてはマルテンサイト変態点よ
りも低温側になっているので、わずかの変形力により見
掛けの降伏現象が起こり、何らの抵抗もなく、変形ひず
みが起こる。<Function> The U-shaped core made of NiTi-based shape memory alloy used in the shoe opening has a martensitic transformation point when worn, that is, at -10°C to 40°C, preferably at -5°C to 35°C. Since the temperature is lower than the actual temperature, a slight deformation force causes an apparent yielding phenomenon, and deformation strain occurs without any resistance.
即ち、一種の双晶変形となり、結晶が向きを変えただけ
の状態になっており、原子間の関係は変形前と同じであ
る。In other words, this is a kind of twinning deformation, in which the crystal has simply changed its orientation, and the relationships between atoms are the same as before the deformation.
従って、変形力が除去されて温度が上昇すると（又は加
温すると）もとに戻って変形ひずみを解消し、所期の形
状は保たれるようになるが、温度上昇前（又は加温前）
は、変形力が加わった状態でもそれに対して特に大きな
抵抗も生じないで、その結果、雇用中の足に食い込んで
足を傷めることはない。勿論、折れてしまって履用不能
となることもない。Therefore, when the deformation force is removed and the temperature rises (or when the temperature rises), the deformation strain returns to its original state and the desired shape is maintained, but before the temperature rise (or before the heating) )
Even when a deforming force is applied, it does not generate any particularly large resistance, and as a result, it does not dig into the foot during employment and cause damage to the foot. Of course, it won't break and become unusable.

口部上縁に包着した。<Example> A wire with a diameter of 1 m and a length of 150 H made of a shape memory alloy with a martensitic phase of 10 to 25°C was made into a U-shape to match the shape of the sheath opening, and a calf (calf leather) upper liquid was made. It was wrapped around the upper edge of the shoe opening.

には折れてしまった。Shoes with the former integrated with the outer sole were used as the shoes of the present invention, and shoes with the latter integrated with the outer sole were used as control shoes.The shoes were worn for 8 hours each day for 3 months. As a result, the shoes of the present invention did not cause any pain in the feet, but the shoes of the control example had a U-shaped shape memory alloy that dug into the feet and damaged the feet on the first day, and eventually broke.
本発明の靴は、時々２５℃以上に加温すると、履口部が
くずれた場合であっても、所期の形状にもどすことがで
きた。When the shoe of the present invention was heated to 25° C. or higher from time to time, even if the shoe opening collapsed, it was able to return to the desired shape.
