Description
【発明の詳細な説明】 〔産業上の利用分野１ 本発明は、形状記憶合金を使用した釣糸に関する。[Detailed description of the invention] [Industrial application field 1 The present invention relates to a fishing line using a shape memory alloy.
［従来の技術］
周知の通り、釣糸は、釣り竿からより戻しまでの道糸と
、釣り針を取付けるためのハリスとからなる。[Prior Art] As is well known, a fishing line consists of a line that runs from a fishing rod to a return line, and a wire for attaching a fishing hook.
従来、このような釣糸は、ナイロン、ピアノ線、ステン
レス鋼、タングステン等からなり、魚の種類、使用状況
等により使い分けられていた。Conventionally, such fishing lines have been made of nylon, piano wire, stainless steel, tungsten, etc., and have been used depending on the type of fish, usage situation, etc.
［発明が解決しようとする課題］
ところで、釣糸は、外気中での針付けや、餌付は作業を
能率よく行うには、ある程度の弾性を有する方が好まし
く、また釣針に掛かった水中の魚の動きに追従するには
、柔軟且つ比重の軽いものほど好ましい。[Problems to be Solved by the Invention] By the way, it is preferable for fishing lines to have a certain degree of elasticity in order to efficiently attach hooks and attach bait in the open air. In order to follow movement, it is preferable that the material is flexible and has a light specific gravity.
ところが、上記した従来の釣針を構成する材料ではこれ
らの特性を兼ね備えて発揮できるものはなく、従って、
従来から、比重が軽く、且つ水上における弾性と水中に
おける柔軟性とを同一の釣糸により発揮できるものが望
まれていた。However, none of the materials used to construct the conventional fishing hooks described above can exhibit all of these characteristics.
Conventionally, there has been a desire for a fishing line that has a light specific gravity and can exhibit both elasticity on the water and flexibility in the water using the same fishing line.
さらに、釣針に掛かった魚は水中で様々な動きをするが
、特に、引っ張られた状態から急激に緩みが生じたとき
釣糸がねじれてキンクし、このキンクした釣糸が再び引
っ張られると比較的小さな荷重により切断するという不
都合が生じる。Furthermore, a fish caught on a hook makes various movements in the water, but in particular, when the fishing line suddenly loosens from being pulled, it twists and kinks, and when the kinked fishing line is pulled again, it becomes relatively small. This causes the inconvenience of cutting due to the load.
このようなキンクによる釣糸の切断を防止するには、水
中における釣糸の柔軟性を確保すると共に、魚の引上げ
荷重に対して伸び率を大きく確保し、さらに釣糸の伸び
に対してこれを元の状態に回復させる必要がある。In order to prevent the fishing line from breaking due to such kinks, it is necessary to ensure the flexibility of the fishing line in the water, ensure a high elongation rate against the pulling load of the fish, and also ensure that the fishing line returns to its original state as the fishing line stretches. need to be restored.
本発明の釣糸は、このような事情に鑑みてなされたもの
で、同一の釣糸により、水中において大きい柔軟性を有
すると共に水上において弾性を発揮し、且つ比重が軽く
、大きい伸び率を有し、この伸びが元の状態に回復する
ような釣糸を提供することを目的とする。The fishing line of the present invention was created in view of these circumstances, and the fishing line of the present invention has high flexibility underwater and elasticity above water, has a light specific gravity, and has a high elongation rate. The purpose of the present invention is to provide a fishing line in which this elongation can be restored to the original state.
［課題を解決するための手段］
上記の課題を解決するために、本発明の釣糸は、低温度
において柔軟性を有すると共に予め設定した変態温度に
温度上昇したとき元の直状なる弾性を回復するようにし
た形状記憶合金を用い、道糸を前記形状記憶合金からな

なる単線により構成したことを特徴とし、前記形状記憶
合金は、Ｎ ｉ −Ｔ ｉ合金よりなることを特徴とす
るものである。[Means for Solving the Problems] In order to solve the above problems, the fishing line of the present invention has flexibility at low temperatures and recovers its original straight elasticity when the temperature rises to a preset transformation temperature. The shape memory alloy is characterized by using a shape memory alloy made of N i -Ti alloy.
［作用］
上記の構成１こより、本発明の形状記憶合金よりなる釣
糸は、水中の低温度中にあるときには柔軟性を有し、そ
れより高温度の水上にあるときには直状なる弾性を回復
するため、従来実現不可能であった、１本の釣糸により
水上における弾性と水中における柔軟性とを兼ね備えて
発揮することができる。[Function] According to the above-mentioned structure 1, the fishing line made of the shape memory alloy of the present invention has flexibility when it is in water at a low temperature, and recovers its straight elasticity when it is on water at a higher temperature. Therefore, a single fishing line can exhibit both elasticity on the water and flexibility in the water, which was previously impossible.
従って、本発明による釣糸を単線としてハリスに用いた
場合、外気中での針付けや、餌付けを行うのに好都合の
真直ぐに張った直状の弾性を発揮する一方、水中では魚
の動きに良く追従する柔軟性を有し、キンクの発生を防
止すると共に、キンクが生じた場合でもその柔軟性によ
りキンクを解いて容易に切断しない。Therefore, when the fishing line according to the present invention is used as a single line for fishing rods, it exhibits straight elasticity that is convenient for hooking and baiting in the open air, while it follows the movement of fish well in the water. It has the flexibility to prevent the occurrence of kinks, and even if kinks occur, the flexibility allows the kinks to loosen and prevents them from being easily cut.
また、本発明による釣糸を撚り線として道糸に用いた場
合、強靭なる大径の道糸を得る反面、その挙動は柔軟で
あって魚の動きに良く追従し、ハリスの場合と同様、キ
ンクの発生を防止し、またキンクが生じた場合でも容易
に切断しない。In addition, when the fishing line according to the present invention is used as a stranded fishing line, the fishing line is strong and has a large diameter, but its behavior is flexible and follows the movement of fish well, and as with Harris, it does not have kinks. This prevents kinks from occurring and does not easily cut them even if they occur.
さらに、水中の低温度中における伸びによる歪は、水上
の温度上昇による形状記憶効果により完全に元の状態に
回復する。Furthermore, the strain caused by elongation at low temperatures underwater is completely restored to its original state due to the shape memory effect caused by the rise in temperature above water.
本発明の釣糸は、Ｎ ｉ −Ｔ ｉ合金よりなる形状記
憶合金により構成し、Ｎｉ−Ｔｉの成分比により特定の
温度を境界として形状回復効果を発揮するものである。The fishing line of the present invention is made of a shape memory alloy made of a Ni-Ti alloy, and exhibits a shape recovery effect at a certain temperature depending on the Ni-Ti component ratio.
〔実施例］ 以下、本発明の詳細な説明する。〔Example] The present invention will be explained in detail below.
本発明の釣糸を構成する形状記憶合金としてはＮ ｉ
−Ｔ ｉ合金を用いる。As the shape memory alloy constituting the fishing line of the present invention, Ni
-Using Ti alloy.
形状記憶合金の変態温度は、Ｎｉ−Ｔｉ成分比により設
定して形状記憶効果を発揮することができる。The transformation temperature of the shape memory alloy can be set depending on the Ni-Ti component ratio to exhibit the shape memory effect.
変態温度の設定温度は、魚の種類及び季節による外気の
常温と水温とにより設定する。The set temperature of the metamorphosis temperature is set based on the outside air temperature and water temperature depending on the type of fish and the season.
例えば、鮎釣りの場合、５月においては水温を約１８度
に設定し、９月においては水温を約２５度に設定し、水
中にある釣糸が設定温度以下で柔軟性を有し、水上の外
気に触れて設定温度より上昇したとき弾性を有した直状
体となるよう形状を回復させるものとする。For example, in the case of sweetfish fishing, the water temperature is set at about 18 degrees in May and about 25 degrees in September. When exposed to outside air and the temperature rises above the set temperature, the shape is restored to an elastic rectilinear body.
ちなみに、水温１８〜２５℃において、Ｎｉ−Ｔｉの成
分比を、Ｎｉ ５０％に対してＴｉ５０％とすることに
より、低温度の水面下において柔軟性を有し、それより
高温の水上において真直張った直状なる弾性を有する形
状回復効果を発揮することができる。By the way, at a water temperature of 18 to 25 degrees Celsius, by setting the Ni-Ti component ratio to 50% Ni to 50% Ti, it has flexibility under water at low temperatures, and can be stretched straight above water at higher temperatures. It is possible to exhibit a shape recovery effect with straight elasticity.
また、本発明においては、単線の径或は撚り線の本数は
、魚の種類または使用状況に応じて種々のものに設定す
るものとする。Further, in the present invention, the diameter of the single wire or the number of twisted wires are set to various values depending on the type of fish or usage conditions.
次に、本発明のＮｉ−Ｔｉ形状配憶合金による釣糸の特

比較的伸び率の大きいタングステンの引張強度は１ 、
２７ Ｋｇ／ Ｉｌｍ”であるが、本発明の釣糸の場合
３ 、５６ Ｋｇ／ ａｒｍ”を有し、約３倍の引張強
度を有する。Next, when comparing the characteristics of the fishing line made of the Ni-Ti shape memory alloy of the present invention with fishing lines made of other materials, for example,
The tensile strength of tungsten, which has a relatively high elongation rate, is 1,
The fishing line of the present invention has a tensile strength of 3.56 Kg/arm", which is approximately three times as high.
また、上記材料のうちでも比重の軽いステンレスが７．
９の比重を有するのに対し、本発明の釣糸の比重は、６
．４である。Also, among the above materials, stainless steel, which has a light specific gravity, is 7.
9, whereas the fishing line of the present invention has a specific gravity of 6.
．． It is 4.
なお、本発明のＮ ｉ −Ｔ ｉ合金は、ステンレス以
上に錆びにくく、防錆の点でも他の金属系の釣糸より優
れたものである。Note that the N i -T i alloy of the present invention is more resistant to rust than stainless steel, and is superior to other metal-based fishing lines in terms of rust prevention.
［発明の効果］
以上説明したように、本発明の釣糸は、水中の低温下に
おいて柔軟性を有し、且つ比重が軽く。[Effects of the Invention] As explained above, the fishing line of the present invention has flexibility in water at low temperatures and has a light specific gravity.
伸び率が大きいため、水中の魚の挙動に良く追従すると
共に魚の引上げ時の引張荷重にも良く耐えて容易に切断
せず、またその柔軟性によりキンクの発生を阻止すると
共にキンクが生じた場合でも容易に解いて切断要因を除
去する一方、水上の温度上昇により適度の弾性を発揮す
るため、釣針や餌付けの作業性が良く、従来の釣糸では
達成でき得ない実用性を有するものである。Because of its high elongation rate, it follows the behavior of fish in the water well, withstands the tensile load when pulling up fish, and does not easily break, and its flexibility prevents the occurrence of kinks and even when kinks occur. While it is easy to unravel and remove the cause of breakage, it also exhibits appropriate elasticity as the temperature rises above the water, making it easy to hook and bait, and has practicality that cannot be achieved with conventional fishing lines.
