Description

【0001】
【産業上の利用分野】
本発明は、例えば、ルアーフィッシングなどに使用される掛け鈎の改良に関する。
【0002】
【従来の技術】
魚釣りと言えば、従来は釣り上げた魚を料理して食べる事が楽しみの一つと考えられていたが、爆発的な釣りブームの到来により漁場における釣り人の数に対して魚の数が相対的に減少し、釣果を楽しむためには釣った魚を傷つける事なく放流してやるというキャッチ・アンド・リリースというスポーツ的な釣り思想が特にルアーフィッシングにおいて定着して来た。
そのためには、▲1▼掛かった魚をバラさない。▲2▼魚を傷つけない。▲3▼外すときに傷を付けない。という事が重要視されてきた。
【0003】
そこで、従来から使用されて来た掛け鈎(A’)を見てみると、図4に示すように針軸(8’)から延出されたフック部(5’)の先端部内面側にカエリ(9’)が突設されており、これが後述する理由により魚を傷つけていた。
即ち、内面側にカエリ(9’)が形成されている従来の掛け鈎(A’)の場合、掛け鈎(A’)が魚にヒットした場合、釣竿を振るって掛け鈎(A’)を強く引き、フッキングを行うことになるが、この時掛け鈎(A’)はアイ方向(即ち、カエリ(9’)の突出しているフトコロ側)に強く引っ張られるために鋭い鈎先(6’)を持つカエリ(9’)が魚の口に鋭く食い込んで魚の口に切り裂き傷を形成する。
【0004】
又、掛け鈎(A’)を魚から外す場合、片手で魚を掴み、他方の手で掛け鈎(A’)の針軸(8’)を摘まみ、両者を押し当ててフック部(5’)の外側のベントカーブ(即ち、曲げ曲線)に沿って手首をひねるようにして引き抜くが、フック部(5’)はベントカーブの内側に力が掛かりやすく、前述のようにベントカーブの外側に沿ってフック部(5’)を引き抜こうとしてもカエリ(9’)が魚の肉に引っ掛かり、切り裂いてしまうという欠点があった。これは前述のキャッチ・アンド・リリース思想から言えば好ましくないという問題がある。
【0005】
その他、魚が掛かった場合、魚は掛け鈎(A’)から逃れようとして暴れるが、そのときフック部(5’)にかかる力はフック部(5’)を引き伸ばす方向に掛かる事になる。カエリ(9’)はフック部(5’)の先端内側に切り起こしにより突設されているので、その基部には鋭い切り欠きがある。しかも、掛け鈎(A’)は熱処理により最硬度まで高めてあるので、前記切り欠きに衝撃的な引っ張り応力が加わると折損する事がある。前記フック部(5’)にかかる力は、切り欠きを広げようとする引っ張り応力であり強度の点でもカエリ(9’)を内側に設ける事は好ましくなかった。
【0006】
【発明が解決しようとする課題】
本発明の解決課題は、掛かった魚がバレにくく且つ魚を傷つけずしかも外しやすく折損しにくい掛け鈎の開発にある。
【0007】
【課題を解決するための手段】
本願発明の掛け鈎(A)は『針軸(8)と、前記針軸(8)から延出され、フック状に曲成された複数のフック部(5)…とで構成され、前記フック部(5)…の先端部外面側にカエリ(9)…が突設されている掛け鈎 (A) であって
フック部(5)…の鈎先からカエリ(9)…にかけてのフック部(5)…の外側面が削り取られて、前記外側面に一対の削り取り面(13)が形成されており、且つこの削り取り面(13)同士の接する部分に鋭利な刃状の稜線(12)が形成されており、カエリ (9) …の反対側の先端部分の内面が断面円弧状に形成されている』事を特徴とする。
以上
【0008】
これよれば、魚がヒットした瞬間に釣竿を振るって掛け鈎(A)を強く引き、魚の口にフック部(5)を突き刺した場合、掛け鈎(A)の引っ張り方向はカエリ(9)の突出していない内側方向となるので、カエリ(9)が突設されているにも拘わらずカエリ(9)による魚の口に切り裂き作用が生じない。また、カエリ(9)の存在によりフック部(5)が魚の口から抜け落ちにくく、バレが生じにくい。
又、魚が暴れてフック部(5)を引き伸ばす方向に力が加わったとしても、その力はフック部(5)の外面側においては圧縮力として作用するので、カエリ(9)の基部に鋭い切り欠きがあったとしてもカエリ(9)が折損したりフック部(5)が折損したりするような事がない。
【0010】
さらにまた、魚がヒットし、フック部(5)が魚の口に突き立った時に、鈎先(6)の稜線(12)が一種の刃物の役割を果たし、魚の堅い口を切開する働きをなす。これにより、フック部(5)は魚の口に極めてスムーズに刺し込まれて行くことになる。ただし、この稜線(12)は掛け鈎(A)の引っ張り方向に存在しないので、掛け鈎(A)の引っ張りによって魚の口を切り裂いていくという事はない。換言すれば、稜線(12)はフック部(5)の魚の口への刺し込み効果のみを高める事になる。
【0011】
【実施例】
以下、本発明を図示実施例に従って説明する。掛け鈎(A)は3本イカリで、図2から分かるように軸(8a)とフック部(5)とで構成された1本の片掛けの掛け鈎素体(1a)と、中央に釣り糸(4)取り付け用のアイ(7)が形成され、アイ(7)から平行に伸びた軸(8A)が導出され、更にフック部(5)が形成されている両掛けの掛け鈎素体(1A)とで構成されており、両掛けの掛け鈎素体(1A)の軸(8A)に添わせて片掛けの掛け鈎素体(1a)の軸(8a)を配設し、ハンダ付けや接着などで一体化して針軸(8)を形成している。
【0012】
フック部(5)は針軸(8)を中心に約120°で配設されており、各フック部(5)の先端は鋭利な鈎先(6)となっている。また、フック部(5)の先端部外面にはカエリ(9)が切り起こされている。この場合カエリ(9)はに針抜けを防止するだけであるから、小さいもので足る。
勿論、掛け鈎(A)の構成は前記構成に限られず、3本の片掛けの掛け鈎素体(1a)の軸(8a)を束ねて1本の針軸(8)とし、ハンダ付け又は接着によって固定してもよい。この場合、いずれか1つの掛け鈎素体(1a)の軸(8a)の端部にアイ(7)が形成される事になる。
【0013】
また、フック部(5)の鈎先(6)からカエリ(9)かけての先端部分は、例えばアイスピックのように断面円形に形成してもよいが、図3に示すようにフック部(5)の鈎先(6)からカエリ(9)かけての外側面を削り取って前記外側面に一対の削り取り面(13)を形成し、且つこの削り取り面(13)同士の接する部分に先鋭な刃状の稜線(12)を構成するようにしてもよい。この場合先端部分の内面(11)側の断面形状は円弧状である。
【0014】
しかして、この掛け鈎(A)のアイ(7)に釣り糸(4)を取り付け、更に魚種に合わせた疑似餌を取り付け、釣竿を振るってポイントへ投入する。魚が疑似餌に誘われて食いつくとすかさず釣竿を引き、掛け鈎(A)を魚の引きに合わせる。これにより、フック部(5)は瞬間的に魚の口を突き通す。魚は逃れようとして暴れるが、カエリ(9)の働きによって突き通ったフック部(5)は魚の口から抜け落ちる事がない。そして、フック部(5)に加わる力は、掛け鈎(A)のアイ(7)方向、即ち、カエリ(9)の突出していないフック部(5)の内側方向(即ち、フトコロ側)となるので、カエリ(9)が突き通っている部分の肉に接触して切り裂くというような事がなく、カエリ(9)によって魚を傷つける事が少ない。換言すれば、フック部(5)による刺し傷だけになる。
【0015】
強度に付いて言えば、掛かった魚が暴れるとフック部(5)を引き伸ばす方向に力が加わるが、その力はフック部(5)の内面側では引っ張り応力として作用するものの、外面側においては圧縮力として作用するので、カエリ(9)の基部に鋭い切り欠きがあったとしてもこの部分には圧縮応力が働いて切り欠きを押し広げる方向には作用せず、従ってカエリ(9)が折損したりフック部(5)が折損したりするような事がない。
【0016】
また、フック部(5)の先端部分の外側面を削って鋭い稜線(12)を形成した場合、この稜線(12)が一種の刃物の役割を果たし、堅い魚の口を切開する働きをなす。これにより、フック部(5)は魚の口に極めてスムーズに刺し込まれて行くことになる。ただし、この稜線(12)は掛け鈎(A)の引っ張り方向に存在しないので、掛け鈎(A)の引っ張りによって魚体を切り裂いていくという事はなく、稜線(12)はフック部(5)の魚体への刺し込み効果のみを高める事になる。
【0017】
又、掛け鈎(A)を外す場合、片手で魚を持ち、他方の手で針軸(8)を摘まみ、フック部(5)のベントカーブに沿って引っ張るだけで内面側に突起物がないので簡単に抜け、魚をカエリ(9)で傷付ける事がない。
【0018】
以上の説明では、3本イカリの掛け鈎(A)の場合を説明したが、勿論これに限られず、2本又は4本以上の場合同様である。又、掛け鈎(A)の用途としてルアーフィッシングを中心に説明したが、本発明の掛け鈎(A)は、ルアーフィッシングのみに限られず、掛け鈎(A)を使用するような場合全てに適用する事ができることは言うまでもない。
【0019】
【発明の効果】
本発明は上記のような構造であるので、掛かった魚がバレにくく且つ魚を傷つけずしかも外しやすい。又、鋭い切り欠きが形成されるカエリの基部には引っ張り応力が加わらず、圧縮力が加わる事になり、カエリやフック部の折損を生じない。

[Industrial applications]
The present invention relates to an improvement of a hook used for lure fishing, for example.
[0002]
[Prior art]
Speaking of fishing, it has been thought that cooking and eating the caught fish was one of the pleasures, but the explosive fishing boom has caused the number of fish to be relatively large compared to the number of anglers at the fishing ground. The catch-and-release sporting idea of catching and releasing fish caught without damaging them in order to enjoy the results has become particularly common in lure fishing.
For that, (1) do not disperse the fish that hangs. (2) Does not hurt the fish. (3) Do not scratch when removing. That has been emphasized.
[0003]
Looking at the hook (A ') that has been used conventionally, as shown in FIG. 4, the hook (5') extending from the needle shaft (8 ') is located on the inner surface of the distal end of the hook (5'). A burrow (9 ') protruded, which had hurt the fish for reasons described below.
That is, in the case of the conventional hook (A ') in which the burrs (9') are formed on the inner surface side, when the hook (A ') hits a fish, the fishing rod is swung to set the hook (A'). At this time, the hook (A ') is strongly pulled in the eye direction (i.e., on the side of the protruding shaft of the burr (9')), so that the sharp hook (6 ') is drawn. A burrow (9 ') having a sharp bite into the mouth of the fish and forms a cut in the mouth of the fish.
[0004]
When the hook (A ') is removed from the fish, the fish is grasped with one hand, the needle shaft (8') of the hook (A ') is gripped with the other hand, and both are pressed against each other to press the hook (5). Twist the wrist along the vent curve (ie, the bending curve) outside the '), but the hook (5') tends to apply force to the inside of the vent curve, as described above. There is a drawback that the burrs (9 ') are caught by the fish meat and cut off when trying to pull out the hook portion (5') along the line. This has a problem that it is not preferable from the viewpoint of the catch and release concept.
[0005]
In addition, when a fish is hooked, the fish runs up trying to escape from the hook (A '). At that time, the force applied to the hook (5') is applied in a direction in which the hook (5 ') is stretched. Since the burrs (9 ') are protruded from the inside of the tip of the hook (5') by cutting and raising, the base has a sharp notch. Moreover, since the hooks (A ') have been hardened to the maximum hardness by heat treatment, the notches may be broken if an impactful tensile stress is applied to the notches. The force applied to the hook portion (5 ') is a tensile stress for expanding the notch, and it is not preferable to provide the burrs (9') inside from the viewpoint of strength.
[0006]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to develop a hook which is hard to be caught by fish and does not damage the fish, and is easy to remove and break.
[0007]
[Means for Solving the Problems]
The hook (A) of the present invention comprises a "needle shaft (8), and a plurality of hook portions (5) extending from the needle shaft (8) and bent into a hook shape. part (5) ... tip burrs on the outer surface (9) of ... is a hanging hook (a) that are projected,
An outer surface of the hook portion (5) from the hook tip of the hook portion (5) to the burrs (9) is scraped off, and a pair of shaving surfaces (13) are formed on the outer surface. A sharp edge-like ridgeline (12) is formed at the portion where the shaving surfaces (13) are in contact with each other, and the inner surface of the tip on the opposite side of the burrs (9) is formed in an arc-shaped cross section. Features.
[0008]
According to this , at the moment the fish hits, swing the fishing rod and pull the hook (A) strongly, and when the hook (5) pierces the mouth of the fish, the pulling direction of the hook (A) is burrs (9) As the burrs (9) are protruded, the burrs (9) do not produce a tearing effect on the mouth of the fish. In addition, the presence of the burrs (9) makes it difficult for the hook part (5) to fall off from the mouth of the fish, and it is difficult for burr to occur.
Further, even if a force is applied in the direction in which the hook part (5) is stretched by the fish being violent, the force acts as a compressive force on the outer surface side of the hook part (5), so that a sharp force is applied to the base of the burrs (9) Even if there is a notch, the burrs (9) and the hook (5) do not break.
[0010]
Furthermore , when the fish hits and the hook (5) protrudes into the mouth of the fish, the ridge (12) of the hook (6) acts as a kind of knife and cuts the hard mouth of the fish. . As a result, the hook portion (5) is inserted very smoothly into the mouth of the fish. However, since the ridgeline (12) does not exist in the pulling direction of the hook (A), the mouth of the fish is not torn by the pull of the hook (A). In other words, the ridgeline (12) enhances only the effect of the hook (5) piercing the fish mouth.
[0011]
【Example】
Hereinafter, the present invention will be described with reference to the illustrated embodiments. As shown in FIG. 2, the hook (A) has three hooks, one single hook hook body (1a) composed of a shaft (8a) and a hook (5), and a fishing line in the center. (4) An eye (7) for attachment is formed, a shaft (8A) extending in parallel from the eye (7) is led out, and a double-hook hook body ( 1A), and the axis (8a) of the single-hanging hook body (1a) is disposed along the axis (8A) of the double-hanging hook body (1A) and soldered. The needle shaft (8) is integrally formed by bonding or bonding.
[0012]
The hooks (5) are disposed at about 120 ° around the needle shaft (8), and the tip of each hook (5) is a sharp hook (6). In addition, burrs (9) are cut and raised on the outer surface of the tip of the hook (5). Since this case burr (9) is only prevents loss needle single, sufficient in small.
Needless to say, the configuration of the hook (A) is not limited to the above-described configuration, and the shaft (8a) of the three single-hook hook bodies (1a) is bundled into one needle shaft (8), and soldering or It may be fixed by bonding. In this case, an eye (7) is formed at the end of the shaft (8a) of any one of the hook bodies (1a).
[0013]
The tip of the hook (5) from the hook (6) to the burrs (9) may be formed in a circular cross section like an ice pick, for example, but as shown in FIG. The outer surface from the hook (6) to the burrs (9) of 5) is scraped to form a pair of scraping surfaces (13) on the outer surface, and a sharp portion is formed at a portion where the scraping surfaces (13) are in contact with each other. You may make it comprise the edge-shaped ridgeline (12). In this case, the cross-sectional shape of the tip portion on the inner surface (11) side is an arc shape.
[0014]
Then, a fishing line (4) is attached to the eye (7) of the hook (A), a pseudo bait according to the type of fish is attached, and the fishing rod is shaken and thrown into the point. When the fish is eaten by the bait and bites, the fishing rod is immediately pulled, and the hook (A) is matched with the pull of the fish. Thereby, the hook part (5) momentarily penetrates the mouth of the fish. The fish rages to escape, but the hook (5) penetrated by the action of the burrow (9) does not fall out of the fish's mouth. Then, the force applied to the hook portion (5) is in the direction of the eye (7) of the hook (A), that is, in the direction of the inside of the hook portion (5) where the burrs (9) do not protrude (that is, on the side of the shaft). Therefore, there is no possibility that the burrow (9) comes into contact with the meat in the part where it penetrates and cuts it, and the burrow (9) scarcely damages the fish. In other words, only the stab wound by the hook portion (5) occurs.
[0015]
In terms of strength, when the hooked fish ramps up, a force is applied in the direction in which the hook (5) is stretched, and the force acts as a tensile stress on the inner surface of the hook (5), but on the outer surface, Since it acts as a compressive force, even if there is a sharp notch in the base of the burrs (9), compressive stress acts on this part and does not act in the direction of expanding the notches, so that the burrs (9) are broken. There is no drip or the hook part (5) is broken.
[0016]
When a sharp ridgeline (12) is formed by shaving the outer surface of the tip portion of the hook portion (5), the ridgeline (12) serves as a kind of blade and functions to cut a hard fish mouth. As a result, the hook (5) is very smoothly inserted into the mouth of the fish. However, since the ridge line (12) does not exist in the pulling direction of the hook (A), the fish body is not torn by the pull of the hook (A), and the ridge line (12) is formed by the hook portion (5). Only the effect of piercing the fish will be enhanced.
[0017]
To remove the hook (A), hold the fish with one hand, pinch the needle shaft (8) with the other hand, and pull along the bent curve of the hook (5). There is no escape and it does not hurt the fish with burrs (9).
[0018]
In the above description, a case has been described in three anchor of hanging hook (A), of course not limited to this is also the case for more than two or four. Also, the description of the use of the hook (A) has been mainly focused on lure fishing, but the hook (A) of the present invention is not limited to lure fishing only, and is applicable to all cases where the hook (A) is used. It goes without saying that you can do it.
[0019]
【The invention's effect】
Since the present invention has the above-described structure, the fish that is caught is less likely to be barred, and is not easily damaged and easily removed. In addition, a tensile force is not applied to the base of the burrs where the sharp notch is formed, and a compressive force is applied, so that burrs and breakage of the hook portion do not occur.
