【発明の詳細な説明】 〔産業上の利用分野〕 本発明は靴の形状を保持するために形状記憶合金を装着
した靴に関する。TECHNICAL FIELD The present invention relates to a shoe equipped with a shape memory alloy in order to maintain the shape of the shoe.
従来から、靴の使用による変形とくに履口の拡大形状の
崩れを防止するために、履口に形状記憶合金を使用する
こと自体は特開昭58-13706号公報、実開昭63-59505号公
報、実開昭63-77502号公報、実開昭63-127405号、実開
昭63-166007号公報、実開昭63-185606号公報等に開示さ
れているように本願の出願前から公知である。Conventionally, in order to prevent the deformation due to the use of shoes, especially the collapse of the enlarged shape of the mouth, the use of a shape memory alloy in the mouth itself has been disclosed in JP-A-58-13706 and JP-A-63-59505. As disclosed in Japanese Utility Model Laid-Open No. 63-77502, Japanese Utility Model Laid-Open No. 63-127405, Japanese Utility Model Laid-Open No. 63-166007, Japanese Utility Model Laid-Open No. 63-185606, etc., it is known before the application of the present application. .
ところが、上記従来の形状記憶合金を取付けた靴は、使
用者が靴を履いた状態における形状の崩れを防止するた
めに、形状記憶合金として専らその加熱による形状復活
温度Af′点が常温あるいは常温以下にあるものが使用さ
れてきた。However, in order to prevent the user from wearing the shoe with the conventional shape memory alloy, the shape recovery temperature Af 'point due to the heating of the shape memory alloy is kept at room temperature or room temperature in order to prevent the user from wearing the shoe. The following have been used.
そのため、人が靴を履いた状態においては使用した形状
記憶合金は強い弾性を有し、これが使用中足首部分に喰
い込み痛みを与えたり、長期間の履用で形状記憶合金が
折れたりするという欠点があり、そのため、折角靴本来
のデザイナーが意図した靴の履き心地が失われるという
欠点があり、とくに靴の履き心地を重視した高級靴には
適用されていなかった。Therefore, when a person wears shoes, the shape memory alloy used has strong elasticity, which causes biting pain in the ankle portion during use, or the shape memory alloy may break during long-term wearing. However, there is a defect that the original comfort of the shoes intended by the original designer of the shoes is lost, and it has not been applied to high-class shoes that particularly emphasize the comfort of shoes.
本発明において解決すべき課題は、従来の靴に形状記憶
合金を取付ける基本的な考え方から脱却して、使用中は
靴本来のデザインから来る履き心地を享受することがで
き、靴を脱いだときに、形状崩れを積極的に矯正する機
能を有する靴を提供することにある。The problem to be solved in the present invention is to break away from the basic idea of attaching a shape memory alloy to a conventional shoe and to enjoy the comfort that comes from the original design of the shoe during use, and when the shoe is taken off Another object is to provide a shoe having a function of positively correcting a shape collapse.
本発明の靴は、加熱により形状が回復する温度Af′点が
40〜50℃の間にある形状記憶合金からなる形状保持材を
装着したことを特徴とする。The shoe of the present invention has a temperature Af ′ point at which the shape is recovered by heating.
It is characterized in that a shape-retaining material made of a shape-memory alloy between 40 and 50 ° C is attached.
本発明において、加熱により形状が回復する温度Af′点
は、直線材を０℃付近で45°に曲げたのち、徐々に昇温
する過程で直線状に復活する温度によって特定するもの
である。In the present invention, the temperature Af 'point at which the shape is restored by heating is specified by the temperature at which the linear material is bent to 45 ° near 0 ° C and then linearly restored in the process of gradually increasing the temperature.
このAf′点は、四季を通して定温とすることもできる
が、夏期では50℃近傍、冬季では40℃近傍のものが好ま
しい。The Af 'point can be kept constant throughout the four seasons, but it is preferably around 50 ° C in summer and around 40 ° C in winter.
このような、Af′点を有する合金としては、例えば、昭
和62年６月23日日刊工業新聞社発行「形状記憶合金とそ
の使い方」の第203頁に記載のTi-Ni合金の組成を適宜変
更して使用できる。As such an alloy having the Af ′ point, for example, the composition of the Ti—Ni alloy described in “Shape Memory Alloy and its Usage” on page 203 of the Nikkan Kogyo Shimbun, June 23, 1987 is appropriately used. Can be changed and used.
靴を履いた状態における足の温度は、外気の温度にもよ
るが、通常の場合、35℃から20℃の間にあり、この使用
温度は上記Af′点より以下の温度で使用される。The temperature of the foot in the state of wearing shoes depends on the temperature of the outside air, but it is usually between 35 ° C. and 20 ° C., and the operating temperature is below the Af ′ point.
そのため、形状保持材として使用されている形状記憶合
金の弾性はAf′点以上の場合より低い弾性値で使用され
ることになる。Therefore, the elasticity of the shape memory alloy used as the shape-retaining material is used at a lower elastic value than that at the point of Af ′ or higher.
したがって、靴本来の履き心地が形状記憶合金製の形状
保持材の弾性によって影響を受けることがなく、靴自体
の設計通りの履き心地が得られる。Therefore, the original comfort of the shoe is not affected by the elasticity of the shape-retaining material made of the shape memory alloy, and the comfort of the shoe as designed can be obtained.
第１図に１として示す形状保持材を下記の表に示す各種
の形状記憶合金を用いて作成した。形状保持材１は径が
1mm、長さ150mmの針金をＵ字状に成形した後、450℃で
熱処理して形状記憶処理を行った。The shape-retaining material shown as 1 in FIG. 1 was prepared using various shape memory alloys shown in the following table. The shape-retaining material 1 has a diameter
A wire having a length of 1 mm and a length of 150 mm was formed into a U shape, and then heat treated at 450 ° C. to perform shape memory treatment.
次いで、この形状記憶処理後の成形体を氷水中に30分浸
漬したのち、第２図に示すように直線部を45°に曲げ、
その後、全体を徐々に昇温する過程で全体形状が第１図
に示す形状に回復する温度を以てAf′点とした。Next, after immersing the shaped body after the shape memory treatment in ice water for 30 minutes, bend the straight portion to 45 ° as shown in FIG.
After that, the temperature at which the overall shape recovers to the shape shown in FIG.
第１表に使用した各合金組成と上記の方法で測定したA
f′点を示す。Each alloy composition used in Table 1 and A measured by the above method
The f'point is shown.
同表においてNo.1〜No.2は本発明の実施例であり、また
No.3は比較例を示す。In the table, No. 1 to No. 2 are examples of the present invention, and
No. 3 shows a comparative example.
形状を回復した成形体のその先端部をエポキシ樹脂２に
よって処理して靴を傷めないための保護処理を行って形
状保持部材とし、これを第３図に示すカンガルー革製の
スリッポンタイプの靴の履き口３に適用した。 The tip of the molded body whose shape has been restored is treated with epoxy resin 2 to protect it from damage to the shoe, and used as a shape-retaining member. This shape-retaining member is used as a slip-on shoe made of kangaroo leather shown in FIG. Applied to the mouthpiece 3.
外気温度が18℃における上記形状保持部材１との人体の
足首の当接部分における表面温度は28℃の状態で１日当
たり８時間の履用を行った。When the outside air temperature was 18 ° C., the surface temperature of the contact part of the ankle of the human body with the shape-retaining member 1 was 28 ° C., and the wear was performed for 8 hours per day.
No.1及びNo.2の合金による保持材を使用した靴は履心地
も良く、６カ月間の履用でも形状記憶合金に異状はな
く、履口形状の変形はわずかであった。The shoes using the holding material made of the No. 1 and No. 2 alloys were comfortable to wear, and even after 6 months of wear, there was no abnormality in the shape memory alloy, and the deformation of the mouth shape was slight.
これに対して、No.3の合金による保持材を使用した靴は
履き始めより痛みを感じたが、そのまま我慢して履用を
続けたところ４カ月目に片方の形状記憶合金が折れたた
め履用を中止した。On the other hand, the shoes using the No. 3 alloy holding material felt pain from the beginning, but when I put up with it and continued to wear it, one of the shape memory alloys broke at the end of the 4th month. I stopped using it.
この結果、本発明の場合、保持材の弾性が履用中は略60
％に低下して足首を圧迫することがないことによる。As a result, in the case of the present invention, the elasticity of the holding material is about 60 during wearing.
% Because it does not press down on the ankle.
さらにNo.1及びNo.2の靴の履口部を強制的に変形させ、
ドライヤーによってAf′点以上に加温させたところ、ほ
ぼ元の履口形状に戻った。In addition, forcibly deform the mouth of No. 1 and No. 2 shoes,
When heated to above the Af 'point with a dryer, it almost returned to its original shape.
本発明によって以下の効果を奏することができる。 The following effects can be achieved by the present invention.
（１） 通常の高級靴と同一の履心地が得られ、履口形
状の変形が少ない。(1) The same comfort as ordinary high-quality shoes is obtained, and the shape of the mouth opening is not significantly deformed.
（２） 長期間の履用にも形状記憶合金が耐え得ること
ができ、勿論破損することもない。(2) The shape memory alloy can withstand long-term wear and is of course not damaged.
（３） 長期間の履用で、靴の履口が変形した場合で
も、ドライヤー等で加温すると元の履口形状にもどる。(3) Even if the mouth of the shoe is deformed after being worn for a long time, it will return to its original shape when heated with a dryer.
