Description
【考案の詳細な説明】 本考案は釣針用コースに関する。[Detailed explanation of the idea] The present invention relates to a course for a fishhook.
従来、鮪はえなわ漁などに用いられる釣針用コースとし
ては馬蹄型をなしたナイロン製のものが用いられている
が、ナイロン製のものは腰が柔らかく釣針に魚がかかっ
たときループ部の先端に荷重が集中し変形し易く、先端
部が鋭角となりここより破断し易い欠点を有している。Conventionally, a horseshoe-shaped nylon hook course has been used for tuna longline fishing, etc., but the nylon hook course has a soft waist and the loop part is soft when a fish is hooked on the hook. It has the disadvantage that the load is concentrated on the tip, which makes it easily deformed, and the tip has an acute angle, making it more likely to break.
この欠点を無くすため単にナイロンを金属に転換したと
きは、その馬蹄型の開口部での金属と釣糸の接触によっ
て釣糸が切れ易くなり好ましくない。If nylon were simply replaced with metal in order to eliminate this drawback, the fishing line would easily break due to contact between the metal and the fishing line at the horseshoe-shaped opening, which is undesirable.
本考案はこの欠点を解消した釣針用コースを提案するも
のであり、繰り返し曲げ許容応力が１００ｋｇ ／ｃ！
１以上のもの、例えばステンレス、真鋳等の金属−或い
はポリカーボネイト、ポリアセタール。The present invention proposes a fishing hook course that eliminates this drawback, and has a repeated bending allowable stress of 100 kg/c!
One or more materials, such as metals such as stainless steel and brass, or polycarbonate and polyacetal.
ＡＢＳ樹脂等の合成樹脂等を用い、外側に凹みを有し一
部開口した押型をなし、該開口先端部は全体としての押
型よりも更に彎曲させてなる。A mold made of a synthetic resin such as ABS resin is partially opened and has a recess on the outside, and the tip of the opening is more curved than the mold as a whole.

２図はその一部断面を示す正面図である。FIG. 1 is a perspective view of a fishhook course according to the present invention, and FIG. 2 is a partially sectional front view thereof.
第３図に本考案に係る釣針用コース１を用いて釣針２に
釣糸３を取り付けたものであり、４は締め具である。FIG. 3 shows a fishing line 3 attached to a fishhook 2 using the fishhook course 1 according to the present invention, and 4 is a fastener.
第１図〜第３図より明らかなように本考案釣針用コース
は全体として一部開口した押型ななすが、その開口先端
部は該押型よりも更に内側に向って彎曲させてあり、そ
の彎曲面の曲率半径Ｒは０．１〜３．５ｍｍである。As is clear from Figures 1 to 3, the fishhook course of the present invention has a partially opened press mold as a whole, but the tip of the opening is curved further inward than the press mold. The radius of curvature R of the surface is 0.1 to 3.5 mm.
又、該先端部彎曲部前卵型部か“らの２本の接線の交点
の角θを１０°〜９００−好ましくは２０’ 〜４０
° である形状のものである。Further, the angle θ of the intersection of two tangents from the front oval part of the curved tip portion is 10° to 900°, preferably 20° to 40°.
° It is of a shape.
かくの如く形成することによって開口部近辺における糸
切れのおそれは解消される。By forming the thread in this manner, the fear of thread breakage near the opening is eliminated.
また繰り返し曲げ許容応力が１００ｋｇ／−以上のもの
を用いることにより魚がかかり荷重がかかったときにお
いても変形のおそれはなく、局部的に荷重がかかること
もない。Furthermore, by using a material with a repeated bending allowable stress of 100 kg/- or more, there is no fear of deformation even when a load is applied to the fish, and no load is applied locally.
