付けられたワイヤ状の形状記憶合金とを有してなり、前
記形状記憶合金は前記弾性部材を弧状に湾曲させること
となる長さを記憶しているものである。(Means for Solving the Problems) A shape memory alloy device according to the present invention includes an elastic member having elasticity and a wire-shaped shape memory alloy having both ends attached to different locations of the elastic member. Thus, the shape memory alloy remembers the length by which the elastic member is curved into an arc.
本発明においては、形状記憶合金は弾性部材の弾性によ
り引娘り力を作用されているので、常温の状態では伸び
変形を受けており、したがってこのとき弾性部材の湾曲
は比較的に小さくなっている。In the present invention, since the shape memory alloy is subjected to a pulling force due to the elasticity of the elastic member, it is subjected to elongation deformation at room temperature, and therefore the curvature of the elastic member becomes relatively small at this time. There is.
しかし、形状記憶合金を適当な温度にまで加熱すると、
該合金はマルテンサイト相から母相への逆変態を行い、
記憶形状の全長に戻ろうとする形状記憶回復力を発生し
、弾性部材の弾性に抗して収縮する。これにより、弾性
部材はより大きく弧状に湾曲する。However, when shape memory alloys are heated to an appropriate temperature,
The alloy undergoes reverse transformation from martensitic phase to parent phase,
It generates a shape memory recovery force that attempts to return to the full length of the memorized shape, and contracts against the elasticity of the elastic member. As a result, the elastic member curves into a larger arc.
また次に、形状記憶合金の加熱を停止すると、該合金は
冷却し、形状回復力を失うので、再び弾性部材の弾性に
より伸び変形を受けるから、弾性部材は比較的小さな湾
曲を示すようになる。Next, when the heating of the shape memory alloy is stopped, the alloy cools down and loses its shape recovery ability, and is again subjected to elongation deformation due to the elasticity of the elastic member, so that the elastic member exhibits a relatively small curvature. .
以下、本発明を図面に示す実施例に基づいて説明する。 Hereinafter, the present invention will be explained based on embodiments shown in the drawings.
第１図から３図までは本発明の一実施例を示す。1 to 3 show one embodiment of the present invention.
この実施例において、１は弾性を有する細長い合成樹脂

端子６，７には、１−ｉ−Ｎｉ合金からなるワイヤ状の
形状記憶合金８の両端部がそれぞれかしめられている。In this embodiment, reference numeral 1 is an elastic member made of an elongated elastic synthetic resin plate, and this elastic member 1 is in a straight state in a free state where no external force is applied. Terminals 6 and 7 are fixed to both ends of the elastic member 1 by screws 2 and 3 and nuts 4 and 5, respectively. Both ends of a wire-shaped shape memory alloy 8 made of a 1-i-Ni alloy are caulked to the terminals 6 and 7, respectively.
ここで、前記形状記憶合金８は、その全長がある寸法り

８の曲げ変形および捩り変形からの形状回復力は無視で
きるので、形状記憶合金８は前記全長りとなる形状を記
憶していさえすれば、真直ぐな形状を記憶していてもよ
いし、湾曲した形状を記憶していてもよい。Here, the shape memory alloy 8 memorizes a shape having a certain size over its entire length, and when the shape memory alloy 8 assumes this shape, the elastic member 1 is compared as shown in FIG. It is curved into a large arc. In addition, in the present invention, since the shape recovery force from elongation deformation of the wire-shaped shape memory alloy 8 is fully utilized, the shape recovery force from bending deformation and torsional deformation of the shape memory alloy 8 can be ignored. The memory alloy 8 may memorize a straight shape or a curved shape as long as it memorizes the shape of the entire length.
次に、本実施例の作動を説明する。Next, the operation of this embodiment will be explained.
本装置においては、形状記憶合金８は弾性部材１の真直

ているので、常温の状態では伸び変形を受けており、し
たがって弾性部材１の湾曲は第１図のように比較的に小
さくなっている。In this device, the shape memory alloy 8 is subjected to a tensile force due to the elasticity of the elastic member 1 that tries to return to its straight state, so it is subjected to elongation deformation at room temperature, and therefore the bending of the elastic member 1 is As shown in Figure 1, it is relatively small.
しかし、端子６．７を通じて形状記憶合金８に電流を流

加熱すると、該合金８はマルテンサイト相から母相への
逆変態を行い、記憶形状の仝艮りに戻ろうとする形状記
憶回復力を発生し、弾性部材１の弾性に抗して収縮する
。これにより、第２図のように弾性部材１はより大きく
弧状に湾曲する。However, when the shape memory alloy 8 is heated to an appropriate temperature by a method such as passing an electric current through the shape memory alloy 8 through the terminal 6.7, the alloy 8 undergoes a reverse transformation from the martensitic phase to the parent phase. It generates a shape memory restoring force that attempts to return to the memory shape, and contracts against the elasticity of the elastic member 1. As a result, the elastic member 1 is curved into a larger arc as shown in FIG.
また次に、形状記憶合金８の加熱を停止すると、該合金
８は冷却し、形状回復力を失うので、再び弾性部材１の
弾性により伸び変形を受け、弾性部材１は第１図のよう
に比較的小さな湾曲を示すようになる。Next, when the heating of the shape memory alloy 8 is stopped, the alloy 8 cools down and loses its shape recovery power, so it is again subjected to elongation deformation due to the elasticity of the elastic member 1, and the elastic member 1 becomes as shown in FIG. It shows a relatively small curvature.
このように本装置では、形状記憶合金８を加熱冷却する
ことにより、弾性部材１の湾曲の度合を変化させること

冷却に伴う弾性部材１の湾曲の度合の変化は種々の用途
に利用することができる。In this manner, in this device, the degree of curvature of the elastic member 1 can be changed by heating and cooling the shape memory alloy 8. Then, the shape memory alloy 8 is heated and
Changes in the degree of curvature of the elastic member 1 due to cooling can be utilized for various purposes.

は言うまでもない。In addition, in the above embodiment, Ti-Ni was used as the shape memory alloy.
Although an alloy is used in the present invention, it goes without saying that a shape memory alloy of the type 5- can also be used.
以上のように本発明による形状記憶合金装置は、構造が
極めて簡単で、製造コストを極めて安価にすることがで
