Description

本発明は、釣竿に用いる釣糸ガイドに関する。   The present invention relates to a fishing line guide used for a fishing rod.

一般に、釣糸ガイドは、釣糸が釣り竿の表面に付着するのを防止するために、間隔をおいて釣り竿の外側に取付けられる。このような釣糸ガイドには、ガイドリングを金属製のフレームで保持し、このガイドリングを保持する保持部から釣り竿の長手方向に向けて取付足を前後方向に延ばし、これらの取付足を介して釣り竿に固定するものがある（例えば特許文献１参照）。   In general, the fishing line guide is attached to the outside of the fishing rod at intervals to prevent the fishing line from sticking to the surface of the fishing rod. In such a fishing line guide, the guide ring is held by a metal frame, and the attachment foot is extended in the front-rear direction from the holding portion for holding the guide ring in the longitudinal direction of the fishing rod. Some are fixed to a fishing rod (see, for example, Patent Document 1).

特開２００６−３４０６６１号公報JP 2006-340661 A

従来の釣糸ガイドは、フレームをステンレス鋼やチタン合金等の金属製の一枚の板材料をプレス加工等で成形した一体構造に形成してあるため、釣竿に取付けると、釣竿の撓り性を阻害する。仮に、取付足を釣竿の撓みに沿って撓ませると、永久変形を生じさせ、釣竿が破損する原因となる。通常、このような取付足は、固定用の糸の糸巻作業が容易となるように、自由端に向けて次第に薄くなるように形成してあるが、金属で形成した取付足を撓み易くすることはできない。   Conventional fishing line guides have a frame that has a single-piece structure made by pressing a single plate of metal such as stainless steel or titanium alloy, so that when attached to a fishing rod, the flexibility of the fishing rod is improved. Inhibit. If the mounting foot is bent along the deflection of the fishing rod, permanent deformation occurs, causing the fishing rod to break. Usually, such mounting feet are formed so as to become thinner gradually toward the free end so that the threading operation of the fixing thread is facilitated, but the mounting feet made of metal should be easily bent. I can't.

このような従来の釣糸ガイドは、釣竿の撓りを阻害し、糸巻固定した取付足の端部にクラックが発生する不都合があり、その改善が強く望まれている。   Such a conventional fishing line guide has a disadvantage that it hinders the bending of the fishing rod and causes a crack to occur at the end of the attachment foot fixed with the bobbin winding.

本発明は、このような事情に基づいてなされたもので、釣竿の撓り性を向上させると共に、釣糸ガイドを取付けた部分でクラックが発生するのを防止することを目的とする。   The present invention has been made based on such circumstances, and it is an object of the present invention to improve the flexibility of a fishing rod and prevent the occurrence of cracks at a portion where a fishing line guide is attached.

更に、釣糸を案内する釣糸案内部と、この釣糸案内部を支える支脚部と、この支脚部に一体に形成した固定部とを有し、この固定部を介して竿管に固定される繊維強化樹脂製のフレームを備える釣糸ガイドであって、前記固定部は、支脚部側領域よりも剛性の小さい低剛性領域を自由端側に有し、この低剛性領域は、自由端から固定部の全長の１／３〜１／４の範囲にわたって、厚さが支脚部側領域の厚さの８０〜３０％、又は、曲げ剛性が支脚部側領域の曲げ剛性の５０〜２０％に形成された部分を有する釣糸ガイドが提供される。   Furthermore, the fiber reinforcement which has a fishing line guide part which guides a fishing line, a supporting leg part which supports this fishing line guide part, and a fixing part formed integrally with this supporting leg part, and is fixed to a rod pipe through this fixing part. A fishing line guide provided with a resin frame, wherein the fixed portion has a low rigidity region on the free end side that is less rigid than the support leg side region, and the low rigidity region extends from the free end to the entire length of the fixed portion. The thickness is 80 to 30% of the thickness of the supporting leg side region, or the bending rigidity is 50 to 20% of the bending rigidity of the supporting leg side region over the range of 1/3 to 1/4 of A fishing line guide is provided.

前記支脚部側領域は、支脚部の固定側領域と共に屈曲部を形成し、この屈曲部内の強化繊維の一部が前記低剛性領域で断絶することが好ましい。   The support leg side region preferably forms a bent portion together with the fixed side region of the support leg portion, and a part of the reinforcing fibers in the bent portion is cut off in the low rigidity region.

前記固定部は、全長の半分以上の長さにわたって、自由端側に向けて厚さがテーパ状に薄くなるテーパ状部を有し、前記低剛性領域は、このテーパ状部に形成されてもよい。   The fixing portion has a tapered portion whose thickness is tapered toward the free end over a length of more than half of the entire length, and the low-rigidity region is formed in the tapered portion. Good.

また、本発明によれば、前記フレームが、前記支脚部から固定部の支脚部側領域まで連続した繊維強化樹脂又は強化繊維を有する上述のいずれか１つ釣糸ガイドを、このフレームの固定部を介して竿管の外側に固着した釣竿が提供される。   According to the present invention, any one of the above-described fishing line guides, wherein the frame has a fiber reinforced resin or a reinforced fiber continuous from the support leg portion to the support leg side region of the fixing portion, the fixing portion of the frame is used. A fishing rod fixed to the outside of the rod tube is provided.

また、前記固定部に、竿管の釣糸ガイド取付部位における軸長方向強化繊維よりも低弾性率の強化繊維が配設され、又は、固定部の長手方向に対して１０度以上の角度で配向された強化繊維が主体に配設された上述のいずれか１つ釣糸ガイドを装着した釣竿が提供される。   In addition, reinforcing fibers having a lower elastic modulus than the reinforcing fibers in the axial length direction at the fishing line guide attachment portion of the rod tube are disposed in the fixing portion, or oriented at an angle of 10 degrees or more with respect to the longitudinal direction of the fixing portion. There is provided a fishing rod equipped with any one of the above-described fishing line guides in which the reinforced fibers are mainly disposed.

本発明の釣糸ガイドによると、繊維強化樹脂製フレームが、竿管に固定する固定部の全長の半分以上にわたって、支脚部側よりも剛性の小さな低剛性領域を自由端側に形成されることにより、竿管の撓り性が阻害されることなく、固定部端部クラックの発生も防止される。   According to the fishing line guide of the present invention, the fiber reinforced resin frame is formed on the free end side with a low rigidity region having a rigidity smaller than that of the support leg part over more than half of the total length of the fixing part fixed to the rod pipe. The occurrence of cracks at the end of the fixed portion is also prevented without impairing the flexibility of the soot tube.

また、釣糸ガイドの繊維強化樹脂製フレームが、竿管に固定する固定部に、支脚部側領域よりも剛性の小さい低剛性領域を自由端側に有し、この低剛性領域は、自由端から固定部の全長の１／３〜１／４の範囲にわたって、厚さが支脚部側領域の厚さの８０〜３０％、又は、曲げ剛性が支脚部側領域の曲げ剛性の５０〜２０％に形成された部分を有することにより、竿管の撓り性が阻害されることなく、クラックの発生も防止される。   In addition, the fiber reinforced plastic frame of the fishing line guide has a low rigidity region on the free end side, which is less rigid than the support leg side region, in the fixed portion that is fixed to the rod pipe. Over the range of 1/3 to 1/4 of the total length of the fixed part, the thickness is 80 to 30% of the thickness of the support leg side area, or the bending rigidity is 50 to 20% of the bending rigidity of the support leg side area. By having the formed portion, the occurrence of cracks is prevented without impairing the flexibility of the soot tube.

固定部の支脚部側領域が、支脚部の固定側領域と共に屈曲部を形成し、この屈曲部内の強化繊維の一部が低剛性領域で断絶する場合には、上述の効果に加え、更に、屈曲部を変形し難くして、釣糸案内部を安定した状態で支えることができる。   In the case where the support leg side region of the fixed part forms a bent portion together with the fixed side region of the support leg portion, and a part of the reinforcing fibers in the bent portion is cut off in the low rigidity region, in addition to the above-described effects, It is possible to make the bent portion difficult to deform and to support the fishing line guide portion in a stable state.

固定部が、全長の半分以上の長さにわたって、自由端側に向けて厚さがテーパ状に薄くなるテーパ状部を有し、低剛性領域がこのテーパ状部に形成される場合には、上述の効果に加え、更に、糸巻等による固定を容易に行うことができる。   When the fixed portion has a tapered portion whose thickness is tapered toward the free end over the length of more than half of the entire length, and the low rigidity region is formed in this tapered portion, In addition to the above-described effects, it can be easily fixed by a spool or the like.

フレームが支脚部から固定部の支脚部側領域まで連続した繊維強化樹脂又は強化繊維を有し、このフレームの固定部を介して、釣糸ガイドを釣竿の竿管に固着した釣竿は、釣糸ガイド取付部における竿管の軸方向に沿う撓み性が阻害されず、撓り性が向上すると共に、釣糸ガイドによるクラックの発生が防止される。   A fishing rod having a fiber reinforced resin or a reinforcing fiber continuous from the support leg to the support leg side region of the fixed portion, and the fishing line guide fixed to the rod of the fishing rod through the fixed portion of the frame is attached to the fishing line guide. Flexibility along the axial direction of the rod in the section is not hindered, the flexibility is improved, and the occurrence of cracks by the fishing line guide is prevented.

フレームの固定部に、竿管の釣糸ガイド取付部位における軸長方向強化繊維よりも低弾性率の強化繊維が配設され、又は、固定部の長手方向に対して１０度以上の角度で配向された強化繊維が主体に配設された釣糸ガイドを装着した釣竿は、釣糸ガイド取付部における竿管の軸方向に沿う撓み性が阻害されず、撓り性が向上すると共に、釣糸ガイドによるクラックの発生が防止される。   A reinforcing fiber having a lower elastic modulus than the reinforcing fiber in the axial length direction at the fishing line guide attachment portion of the rod pipe is disposed on the fixing portion of the frame, or is oriented at an angle of 10 degrees or more with respect to the longitudinal direction of the fixing portion. A fishing rod equipped with a fishing line guide mainly composed of reinforcing fibers is not hindered by the flexibility of the fishing line guide mounting portion along the axial direction of the fishing pipe, and the flexibility is improved.

図１および図２は、本発明の実施形態による釣糸ガイド１０を示す
本実施形態の釣糸ガイド１０は、釣り竿の竿管８の外面に釣糸が付着するのを防止する外ガイドとして形成してあり、軸方向に僅かな勾配を形成された竿管８の外周面上の所要位置に取付け、例えば糸巻、糸止め、あるいは接着剤等の適宜の固定手段を用いて固定することができる。必要な場合には、適宜の摩擦保持手段により、所要位置に保持し、必要に応じて、前方の穂先側から後方の元側に沿って、竿管８の軸線Ｃと平行な軸方向に前後動し、所要位置に摩擦力で保持するようにしてもよい。 1 and 2 show a fishing line guide 10 according to an embodiment of the present invention. The fishing line guide 10 of this embodiment is formed as an outer guide for preventing the fishing line from adhering to the outer surface of a fishing rod 8 of a fishing rod. It can be attached to a required position on the outer peripheral surface of the soot tube 8 formed with a slight gradient in the axial direction, and can be fixed using an appropriate fixing means such as a spool, a thread stopper, or an adhesive. If necessary, it is held at a required position by appropriate friction holding means, and if necessary, it is moved back and forth in the axial direction parallel to the axis C of the tub tube 8 from the front tip side to the rear base side. It may be moved and held at a required position by a frictional force.

竿管８は通常と同様に、炭素繊維等の強化繊維にエポキシ樹脂等の合成樹脂を含浸した繊維強化プリプレグシートを、強化繊維が周方向、軸長方向あるいは軸長方向に対して適宜角度に傾斜した偏向方向に引き揃えて巻回し、これらの複数の繊維層を積層した中空竿管から形成したものでよい。   In the same manner as usual, the soot tube 8 is a fiber reinforced prepreg sheet obtained by impregnating a reinforced fiber such as carbon fiber with a synthetic resin such as an epoxy resin so that the reinforced fiber is at an appropriate angle with respect to the circumferential direction, the axial length direction, or the axial length direction It may be formed from a hollow soot tube in which the plurality of fiber layers are laminated by being wound in the inclined deflection direction.

この竿管８に取付ける釣糸ガイド１０は、ガイドリング１２を保持する釣糸案内部１４とこの釣糸案内部１４を一端側で支える支脚部１６とを有する板状構造のフレーム１８を備える。このフレーム１８は、支脚部１６の他端側に固定部２０を一体に形成してあり、この固定部２０を糸巻や、接着等の固定手段により竿管８の外面上に固定される。   The fishing line guide 10 attached to the rod pipe 8 includes a plate-like frame 18 having a fishing line guide portion 14 for holding the guide ring 12 and a support leg portion 16 for supporting the fishing line guide portion 14 at one end side. The frame 18 is integrally formed with a fixing portion 20 on the other end side of the support leg portion 16, and the fixing portion 20 is fixed on the outer surface of the tub tube 8 by fixing means such as bobbin winding or adhesion.

釣糸案内部１４には、ガイドリング１２を保持する貫通孔１４ａを形成してあり、この貫通孔１４ａを介して保持されるガイドリング１２は、滑らかな円環状の曲面で形成した内面を釣糸案内面１２ａとして有し、この釣糸案内面１２ａで囲まれた釣糸導通孔を通して釣糸を案内する。   The fishing line guide portion 14 is formed with a through hole 14a for holding the guide ring 12, and the guide ring 12 held through the through hole 14a has a fishing line guide on the inner surface formed by a smooth annular curved surface. The fishing line is guided through a fishing line conduction hole having a surface 12a and surrounded by the fishing line guide surface 12a.

図１には、このガイドリング１２は、釣糸導通孔の中心軸Ｏを竿管８の軸線Ｃとほぼ平行に配向させ、図１の左方に示すように、ロート状に大きく拡径した側の端部１２ｂを魚釣用リール（図示しない）側に向けてフレーム１８で保持された状態で示してある。反対側の端部１２ｃは、端部１２ｂとは反対側に向けて僅かに拡径する。これらの端部１２ｂ，１２ｃの外周側縁部が、釣糸案内部１４の両側から貫通孔１４ａの周縁部に係合し、抜け止めされている。   In FIG. 1, the guide ring 12 has a center line O of the fishing line conduction hole oriented substantially parallel to the axis C of the rod 8 and has a large diameter expanded in a funnel shape as shown on the left side of FIG. This is shown in a state where the end portion 12b is held by the frame 18 toward the fishing reel (not shown) side. The opposite end portion 12c slightly expands in diameter toward the opposite side to the end portion 12b. The outer peripheral side edge portions of these end portions 12b and 12c are engaged with the peripheral edge portion of the through hole 14a from both sides of the fishing line guide portion 14, and are prevented from coming off.

このガイドリング１２は、例えばシリコンカーバイト（ＳｉＣ）、アルミナオキサイト、タングステンカーバイト、セラミックあるいは金属等、フレーム１８よりも耐磨耗性に優れた硬質材料で形成するのが好ましい。   The guide ring 12 is preferably formed of a hard material having higher wear resistance than the frame 18, such as silicon carbide (SiC), alumina oxide, tungsten carbide, ceramic or metal.

このガイドリング１２を保持する釣糸案内部１４は、外周縁部がガイドリング１２の拡径側の端部１２ｂよりも大径のリング状に形成してあり、貫通孔１４ａにガイドリング１２を嵌合して保持したときに、外周縁部がガイドリング１２の外周側に突出する。これにより、ガイドリング１２の端部１２ｂの半径方向寸法が短いものであっても、このガイドリング１２と共に釣糸を確実に案内し、支脚部１６により、竿管８の外面から所要距離に配置される。   The fishing line guide portion 14 that holds the guide ring 12 has an outer peripheral edge formed in a ring shape larger in diameter than the end portion 12b on the enlarged diameter side of the guide ring 12, and the guide ring 12 is fitted into the through hole 14a. When held together, the outer peripheral edge protrudes to the outer peripheral side of the guide ring 12. Thereby, even if the radial dimension of the end portion 12b of the guide ring 12 is short, the fishing line is reliably guided together with the guide ring 12, and is arranged at a required distance from the outer surface of the rod pipe 8 by the support leg portion 16. The

支脚部１６は、釣糸案内部１４の外周縁部から滑らかな曲線状に延びる外縁部１６ａを両側に有し、これらの外縁部が中間部１６ｂ及び固定側領域１６ｃを介して、外縁部１６ａ，１６ａ間の幅を次第に減じつつ固定部２０の両縁部２０ａに滑らかに移行する。これにより、釣糸案内部１４を所要位置に保持するための十分な強度を確保し、更に、釣糸が引っ掛かり易い角部の形成を防止してある。   The support leg portion 16 has outer edge portions 16a extending from the outer peripheral edge portion of the fishing line guide portion 14 in a smooth curved shape on both sides, and these outer edge portions are connected to the outer edge portions 16a, 16c via the intermediate portion 16b and the fixed side region 16c. The width between 16a is smoothly reduced to both edge portions 20a of the fixing portion 20 while gradually decreasing the width. Thereby, sufficient strength for holding the fishing line guide portion 14 at a required position is ensured, and further, formation of a corner portion where the fishing line is easily caught is prevented.

この支脚部１６の両外縁部１６ａ間の幅が、所要強度を維持するために必要とする以上に大きい場合には、図２に示すような凹部１７を板厚方向に貫通させて形成してもよい。このような凹部１７は、１つに限らず、複数設けてもよく、また、貫通形成することなく、釣糸導通孔の中心軸Ｏの軸方向に沿う一方又は双方に凹設させたものでもよい。いずれの場合も、釣糸が引掛かり易い角部又は凸部の無い滑らかな外面を形成することが好ましい。   When the width between the outer edge portions 16a of the support leg 16 is larger than necessary to maintain the required strength, a recess 17 as shown in FIG. Also good. The number of the concave portions 17 is not limited to one, and a plurality of the concave portions 17 may be provided. Further, the concave portion 17 may be provided in one or both along the axial direction of the central axis O of the fishing line conduction hole without being formed to penetrate therethrough. . In any case, it is preferable to form a smooth outer surface that does not have corners or protrusions that are easily hooked by a fishing line.

この支脚部１６は、固定側領域１６ｃに、固定部２０を一体に形成してあり、この固定部２０を竿管８の外面に糸巻・糸止め等で固定することにより、フレーム１８を竿管８に固定することができる。固定部２０をフレーム１８に一体に形成することにより、フレーム１８を軽量化、高剛性化することができる。   This support leg portion 16 is integrally formed with a fixed portion 20 in a fixed side region 16c, and by fixing the fixed portion 20 to the outer surface of the tub tube 8 with a bobbin, a thread stopper or the like, the frame 18 is fixed to the tub tube. 8 can be fixed. By forming the fixing portion 20 integrally with the frame 18, the frame 18 can be reduced in weight and rigidity.

この固定部２０は、固定側領域１６ｃの釣糸案内部１４から離隔した端部とほぼ等しくかつ取付けられる竿管８の外径よりも狭い幅寸法を有する板状形状を有し、支脚部１６に対して反対側の裏面２２が竿管８に載置される載置面を形成する。   The fixing portion 20 has a plate-like shape that is substantially equal to an end portion of the fixing-side region 16c that is separated from the fishing line guide portion 14 and has a width that is narrower than the outer diameter of the rod 8 to be attached. On the other hand, the back surface 22 on the opposite side forms a mounting surface on which the tube 8 is mounted.

固定部２０は、支脚部１６に隣接する支脚部側領域２４と、この支脚部側領域の自由端側に配置されて、支脚部側領域２４よりも剛性を小さく形成された低剛性領域２６とを有する。この低剛性領域２６は、固定部２０の長さの半分以上にわたって形成してあり、支脚部側領域２４から長手方向に沿って順に、厚さが次第に減少する傾斜状部２６ａと、ほぼ一定の厚さを有する中間部２６ｂと、中間部２６ｂから更に厚さが減少する薄肉化部２６ｃとを有する。傾斜部２６ａは、厚さｔ２の支脚部側領域２４から中間部２６ｂの厚さｔ１まで移行し、薄肉化部２６ｃは、中間部２６ｂの厚さｔ１から表面を湾曲しつつ自由端に至り、裏面２２に連結される。   The fixed portion 20 includes a support leg side region 24 adjacent to the support leg portion 16, and a low rigidity region 26 that is disposed on the free end side of the support leg side region and is formed to be less rigid than the support leg side region 24. Have The low-rigidity region 26 is formed over half the length of the fixed portion 20, and an inclined portion 26a whose thickness gradually decreases in order from the support leg-side region 24 along the longitudinal direction, and a substantially constant portion. It has an intermediate portion 26b having a thickness and a thinned portion 26c whose thickness further decreases from the intermediate portion 26b. The inclined portion 26a moves from the support leg side region 24 having a thickness t2 to the thickness t1 of the intermediate portion 26b, and the thinned portion 26c reaches the free end while curving the surface from the thickness t1 of the intermediate portion 26b. Connected to the back surface 22.

なお、厚さｔ１，ｔ２は、中心軸Ｏを通りかつ幅方向の中央を通る面Ｈ内における厚さをいう。また、低剛性とは、曲げ、ねじれ又は伸び等の外力に対して、形状を維持することのできる能力が、支脚部側領域２４よりも小さく、したがって支脚部側領域２４よりも変形し易いことをいい、低剛性領域２６は、固定部２０内で、支脚部側領域２４よりも変形し易い全ての領域を含む。したがって、低剛性領域２６は、その厚さ、幅に関する形状のみで特定されるものではなく、支脚部側領域２４と外形（中心軸Ｏに垂直な断面形状）が同じ寸法又はこれよりも大きい場合であっても、内部の強化繊維の配向方向、含まれる本数、種類、長さ、連続性等によって、曲げ、ねじれ又は伸び方向等の外力に対する剛性が低く形成される場合も含む。   The thicknesses t1 and t2 are thicknesses in a plane H passing through the central axis O and passing through the center in the width direction. The low rigidity means that the ability to maintain the shape with respect to an external force such as bending, twisting, or elongation is smaller than the support leg side region 24 and is therefore more easily deformed than the support leg side region 24. The low-rigidity region 26 includes all regions that are more easily deformed than the support leg-side region 24 in the fixed portion 20. Therefore, the low-rigidity region 26 is not specified only by the shape related to the thickness and width, and the support leg side region 24 and the outer shape (cross-sectional shape perpendicular to the central axis O) are the same size or larger. However, the case where the rigidity with respect to an external force such as a bending, twisting, or extension direction is formed low depending on the orientation direction of the internal reinforcing fiber, the number, type, length, continuity, and the like.

本実施形態の固定部２０は、裏面２２に対して反対側の表面の高さを、支脚部側領域２４から自由端まで次第に減少させてある。傾斜状部２６ａは支脚部側領域２４と中間部２６ｂとの間で、目視できる程度の段部を形成することなく滑らかな外面形状を形成し、薄肉化部２６ｃは、中間部２６ｂと自由端との間で、目視できる程度の段部を形成することなく滑らかな外面形状を形成することが好ましい。薄肉化部２６ｃが固定部２０の自由端側で徐々に薄く形成されることにより、糸巻作業が容易になる。また、薄肉化部２６ｃの先端が竿管８の軸線Ｃ側に回動する力がフレーム１８に作用したときに、竿管８が損傷するのを防止することができる。   In the fixing portion 20 of the present embodiment, the height of the surface opposite to the back surface 22 is gradually decreased from the support leg side region 24 to the free end. The inclined portion 26a forms a smooth outer surface shape between the support leg side region 24 and the intermediate portion 26b without forming a visible stepped portion, and the thinned portion 26c is formed between the intermediate portion 26b and the free end. It is preferable to form a smooth outer surface shape without forming a visible stepped portion. Since the thinned portion 26c is gradually formed thin on the free end side of the fixed portion 20, the bobbin winding operation is facilitated. Moreover, when the force with which the front-end | tip of the thin part 26c rotates to the axis C side of the soot tube 8 acts on the flame | frame 18, it can prevent that the soot tube 8 is damaged.

また、固定部２０の表面は、固定部２０の幅方向に沿って、側縁部２０ａに向けて次第に竿管８側に湾曲する曲面状形状を有してもよい。固定部２０の表面をこのような曲面状に形成することにより、竿管８に固定したときに、釣糸が引掛かり易い角部又は凸部の無い滑らかな外面を形成することができ、また、糸巻き、糸止めが容易となる。   Further, the surface of the fixing portion 20 may have a curved shape that gradually curves toward the side tube 20 toward the side edge portion 20 a along the width direction of the fixing portion 20. By forming the surface of the fixing portion 20 in such a curved surface shape, a smooth outer surface without a corner portion or a convex portion that is easy to catch a fishing line when fixed to the rod tube 8 can be formed. Winding and threading are easy.

なお、固定部２０の裏面２２は、図２に示すような平坦面に形成することも可能であるが、竿管８の外面に沿う湾曲面で形成してもよい。湾曲面に形成する場合には、載置面が竿管８の外面形状に好適に適合し、竿管８に対する固定力を向上することができる。   The back surface 22 of the fixed portion 20 can be formed as a flat surface as shown in FIG. 2, but may be formed as a curved surface along the outer surface of the tub tube 8. In the case of forming on the curved surface, the mounting surface is suitably adapted to the outer surface shape of the soot tube 8, and the fixing force to the soot tube 8 can be improved.

固定部２０と釣糸案内部１４とを連結する支脚部１６は、固定側屈曲部２８ａ及び案内側屈曲部２８ｂを介して、釣糸案内部１４を所要の向き及び位置に配置する。これらの屈曲部２８ａ，２８ｂの屈曲角度を調整することで、固定部２０に対する釣糸案内部１４およびガイドリング１２の姿勢を変更することができる。図１に示すガイドリング１２は、中心軸Ｏを竿管８の軸線Ｃに平行に配置したものであり、これに限らず種々の向きに配向させることができることは明らかである。   The support leg portion 16 that connects the fixed portion 20 and the fishing line guide portion 14 arranges the fishing line guide portion 14 in a required direction and position via the fixed side bent portion 28a and the guide side bent portion 28b. By adjusting the bending angles of these bent portions 28a and 28b, the postures of the fishing line guide portion 14 and the guide ring 12 with respect to the fixed portion 20 can be changed. The guide ring 12 shown in FIG. 1 has a central axis O arranged in parallel to the axis C of the soot tube 8, and is obviously not limited to this and can be oriented in various directions.

固定側屈曲部２８ａは、固定部２０の支脚部側領域２４と、支脚部１６の固定側領域１６ｃとの間に、３０〜９０度の範囲の角度α１を形成し、案内側屈曲部２８ｂは、中間部１６ｄと釣糸案内部１４との間に、０〜４５度の範囲の角度αを形成する。両角度α１，α２を合計した角度すなわち固定部２０に対する釣糸案内部１４の角度を３０度以上、１００度以下とすることが好ましい。   The fixed side bent portion 28a forms an angle α1 in the range of 30 to 90 degrees between the support leg side region 24 of the fixed portion 20 and the fixed side region 16c of the support leg portion 16, and the guide side bent portion 28b An angle α in the range of 0 to 45 degrees is formed between the intermediate portion 16d and the fishing line guide portion 14. It is preferable that the angle obtained by adding both the angles α1 and α2, that is, the angle of the fishing line guide portion 14 with respect to the fixed portion 20 is 30 degrees or more and 100 degrees or less.

固定側屈曲部２８の角度α１が容易に変化するのを防止するため、支脚部１６の固定側領域１６ｃは、固定部２０の支脚部側領域２４とほぼ同じかこれよりも大きな剛性を有することが好ましい。   In order to prevent the angle α1 of the fixed-side bent portion 28 from easily changing, the fixed-side region 16c of the support leg portion 16 has substantially the same or larger rigidity as the support leg-side region 24 of the fixed portion 20. Is preferred.

本実施形態のフレーム１８は、釣糸案内部１４、支脚部１６及び固定部２０保持部１４が強化繊維に合成樹脂を含浸した繊維強化プリプレグを積層して板状形状に形成した積層成形材３０で形成される。フレーム１８の全体を積層成形材３０で形成することにより、その製造工程が簡略化され、軽量構造に形成することができる。   The frame 18 of the present embodiment is a laminated molding material 30 in which a fishing line guide portion 14, a support leg portion 16 and a fixing portion 20 holding portion 14 are formed by laminating fiber reinforced prepregs in which a reinforcing resin is impregnated with a synthetic resin into a plate shape. It is formed. By forming the whole frame 18 with the laminated molding material 30, the manufacturing process is simplified and it can form in a lightweight structure.

図３は、強化繊維の引き揃え方向を種々の方向に配向させる積層成形材３０の積層構造例を示す。このような積層成形材３０は、長繊維の強化繊維を用い、例えば、カーボン繊維、ガラス繊維、ボロン繊維等の高弾性繊維、アラミド繊維、ポリエーテルイミド繊維等の合成樹脂繊維、更に、ＳＵＳ、チタン合金、ＮＴ合金等の金属繊維を使用することができる。また、マトリックス樹脂としては、エポキシ樹脂、フェノール樹脂、シアネート樹脂、ポリエステル樹脂、ビニルエステル樹脂、アクリル樹脂、メラニン樹脂、尿素樹脂等の熱硬化性樹脂を用いることができる。また、熱可塑性樹脂も使用でき、粘着型のゴム系樹脂、アクリル系樹脂、ポリアミド系樹脂又はポリサルファイド樹脂等を用いるものと、ホットメルト型のポリオレフィン系樹脂、ポリエステル樹脂、ポリアミド樹脂、アクリル樹脂、ウレタン樹脂、スチレン−イソプレン−スチレンブロック共重合体又はエチレン−酢酸ビニル共重合体を用いることができる。   FIG. 3 shows an example of a laminated structure of the laminated molding material 30 in which the direction in which the reinforcing fibers are aligned is oriented in various directions. Such a laminated molding material 30 uses long-fiber reinforcing fibers, for example, high elastic fibers such as carbon fibers, glass fibers and boron fibers, synthetic resin fibers such as aramid fibers and polyetherimide fibers, SUS, Metal fibers such as titanium alloy and NT alloy can be used. Further, as the matrix resin, a thermosetting resin such as an epoxy resin, a phenol resin, a cyanate resin, a polyester resin, a vinyl ester resin, an acrylic resin, a melanin resin, or a urea resin can be used. Also, thermoplastic resins can be used, such as those using adhesive rubber resins, acrylic resins, polyamide resins or polysulfide resins, hot melt polyolefin resins, polyester resins, polyamide resins, acrylic resins, urethanes. Resin, styrene-isoprene-styrene block copolymer or ethylene-vinyl acetate copolymer can be used.

この積層成形体３０は、厚さ方向の中央に、強化繊維が固定部２０の長手方向に沿う長手方向の繊維強化樹脂層３２を配置し、この上下に、強化繊維を固定部２０の長手方向に対して交差する方向に指向する交差方向の繊維強化樹脂層３４，３６を配置し、これらの交差方向の繊維強化樹脂層の外側に、強化繊維を織成した織布層３８，３８を配置してある。符号Ｍは積層成形体３０の厚さ方向の中立面を示す。   The laminated molded body 30 has a fiber reinforced resin layer 32 in the longitudinal direction in which the reinforcing fibers extend along the longitudinal direction of the fixing portion 20 at the center in the thickness direction, and the reinforcing fibers are disposed above and below the longitudinal direction of the fixing portion 20. The fiber reinforced resin layers 34 and 36 in the intersecting direction oriented in the direction intersecting with the fiber are disposed, and the woven fabric layers 38 and 38 woven with the reinforcing fibers are disposed outside the fiber reinforced resin layers in the intersecting direction. It is. A symbol M indicates a neutral surface in the thickness direction of the laminated molded body 30.

なお、固定部２０は、図１および図２に示すように、竿管８の軸線Ｃに沿って細長い板状形状に形成するだけでなく、例えば竿管８の周方向寸法の方が竿管８の軸長方向よりも長く形成することも可能であり、または、屈曲部２８ａ，２８ｂを滑らかに連続した１つ湾曲状に形成することも可能である。   As shown in FIGS. 1 and 2, the fixing portion 20 is not only formed in an elongated plate shape along the axis C of the soot tube 8, but, for example, the circumferential dimension of the soot tube 8 is the soot tube. It is also possible to form it longer than the axial length direction of 8, or it is also possible to form the bent portions 28a, 28b in a single curved shape that is smoothly continuous.

厚さ方向の中央に配置する長手方向の繊維強化樹脂層３２は、竿管８の軸長方向又は固定部２０の長手方向に対して強化繊維を０°±５°（又は０°±１０°）の角度で一方向に引き揃えた繊維強化プリプレグを複数層重ねて形成することが好ましい。   The longitudinal fiber reinforced resin layer 32 disposed in the center of the thickness direction is 0 ° ± 5 ° (or 0 ° ± 10 °) of the reinforcing fiber with respect to the axial direction of the tub tube 8 or the longitudinal direction of the fixed portion 20. It is preferable that a plurality of fiber reinforced prepregs aligned in one direction at an angle of

交差方向の繊維強化樹脂層３４は、固定部２０の長手方向に対してそれぞれ２５〜６５度の範囲で、ほぼ４５度が好ましい角度で交差する方向に指向し、かつ、互いに逆方向に配向された内側斜向繊維層３４ａと外側斜向繊維層３４ｂとで形成してある。同様に、長手方向の繊維強化樹脂層３２を挟んで反対側に配置される交差方向の繊維強化樹脂層３６も、固定部２０の長手方向に対してそれぞれ２５〜６５度の範囲で、ほぼ４５度が好ましい角度で交差し、かつ、互いに逆方向に配向された内側斜向繊維層３６ａと外側斜向繊維層３６ｂとを有する。   The fiber reinforced resin layers 34 in the intersecting direction are each oriented in a direction intersecting at a preferred angle of approximately 45 degrees within a range of 25 to 65 degrees with respect to the longitudinal direction of the fixed portion 20 and oriented in opposite directions. The inner oblique fiber layer 34a and the outer oblique fiber layer 34b are formed. Similarly, the cross-direction fiber reinforced resin layer 36 disposed on the opposite side across the longitudinal fiber reinforced resin layer 32 is also approximately 45 in the range of 25 to 65 degrees with respect to the longitudinal direction of the fixed portion 20. It has an inner oblique fiber layer 36a and an outer oblique fiber layer 36b whose degrees intersect at a preferred angle and are oriented in opposite directions.

この繊維強化樹脂層３４，３６の斜向繊維層３４ａ，３４ｂ，３６ａ，３６ｂは、それぞれ竿管８の軸長方向に対して強化繊維を４５°±１５°（又は４５°±３０°）の角度で一方向に引き揃えた繊維強化プリプレグを中央の繊維強化樹脂層３２に重ねて形成することが好ましい。   The oblique fiber layers 34 a, 34 b, 36 a, 36 b of the fiber reinforced resin layers 34, 36 each have a reinforcing fiber of 45 ° ± 15 ° (or 45 ° ± 30 °) with respect to the axial length direction of the soot tube 8. It is preferable to form a fiber reinforced prepreg aligned in one direction at an angle so as to overlap the fiber reinforced resin layer 32 at the center.

このような交差方向の繊維強化樹脂層３４，３６を長手方向の繊維強化樹脂層３２の厚さ方向両側に配置することにより、釣糸ガイド１０の特に固定部２０の軽量化、強度の向上および安定化を図ることができる。   By disposing such fiber reinforced resin layers 34 and 36 in the cross direction on both sides in the thickness direction of the fiber reinforced resin layer 32 in the longitudinal direction, the weight of the fishing line guide 10, in particular, the fixing portion 20 can be reduced in weight, improved in strength and stable. Can be achieved.

なお、織物層３８の繊維束が３つの方向以上の多数の方向に延びる繊維束を組合せて形成される場合には、長手方向の繊維強化樹脂層３２を省略して、積層成形材３０の繊維強化樹脂層を全て織物層３８で形成することも可能である。   In addition, when the fiber bundle of the fabric layer 38 is formed by combining fiber bundles extending in multiple directions of three or more directions, the fiber reinforced resin layer 32 in the longitudinal direction is omitted, and the fibers of the laminated molding 30 It is also possible to form the reinforced resin layer entirely from the fabric layer 38.

図４及び図５は、このような積層成形材３０によるフレーム１８を、金型４０，４２を用いて製造する製造工程の概略を示す。   4 and 5 show an outline of a manufacturing process for manufacturing the frame 18 made of the laminated molding material 30 by using the molds 40 and 42. FIG.

各繊維強化樹脂層３２，３４，３６および織物層３８を形成する繊維強化プリプレグシート（図示しない）を所定形状に切断し、その繊維方向を上述の積層体３０の繊維方向に沿わせて重ね合わせる。積層する繊維強化プリプレグシートの枚数又は層数は、繊維強化プリプレグシートの種類や重ねる条件に応じて任意に調整することができ、例えば一度に積層成形材３０に必要な全体の分を重ね合わせることも可能であるが、複数回に分けることで、各繊維強化プリプレグシート中の強化繊維の動きを少なくした状態で金型４０，４２に高精度でセットすることができる。   A fiber reinforced prepreg sheet (not shown) that forms each of the fiber reinforced resin layers 32, 34, and 36 and the fabric layer 38 is cut into a predetermined shape, and the fiber direction is overlapped along the fiber direction of the laminate 30 described above. . The number of fiber-reinforced prepreg sheets or the number of layers to be laminated can be arbitrarily adjusted according to the type of fiber-reinforced prepreg sheets and the conditions for stacking. For example, the entire required amount of the laminated molded material 30 is overlapped. However, by dividing into a plurality of times, it is possible to set the molds 40 and 42 with high accuracy in a state in which the movement of the reinforcing fibers in each fiber-reinforced prepreg sheet is reduced.

金型４０，４２には、例えば金属材料、鋳物、セラミックス等の適宜の材料で形成してあり、互いに対応した凹部４０ａ，４２ａを複数組形成しておくことが好ましい。これらの金型４０，４２には予め離型剤をコーティングしておき、この凹部４０ａ，４２ａに合わせて積層した繊維強化プリプレグシートをセットする。繊維強化プリプレグシートは、予め重ね合わせた状態でセットしてもよく、一枚ずつ順にセットしてもよい。図示の金型４０，４２は、積層成形材３０の中立面Ｍ（図３）を挟んで上下に型割りしているため、下型である金型４０に繊維強化プリプレグシートを載置し、この金型４０の形状に合わせて保持することができる。凹部４０ａを形成する面を水平に配置してもよく、これを傾斜させてもよく、適宜の方向に配置することができる。   The molds 40 and 42 are formed of an appropriate material such as a metal material, a casting, or ceramics, and it is preferable to form a plurality of pairs of concave portions 40a and 42a corresponding to each other. These molds 40 and 42 are coated with a release agent in advance, and a fiber reinforced prepreg sheet laminated in accordance with the recesses 40a and 42a is set. The fiber reinforced prepreg sheets may be set in a state where they are overlapped in advance, or may be set one by one. Since the illustrated molds 40 and 42 are divided vertically by sandwiching the neutral surface M (FIG. 3) of the laminated molding material 30, a fiber-reinforced prepreg sheet is placed on the lower mold 40. The mold 40 can be held in accordance with the shape. The surface on which the recess 40a is formed may be disposed horizontally, may be inclined, and can be disposed in an appropriate direction.

繊維強化プリプレグを金型４０にセットした後、上型である金型４２で繊維強化プリプレグを加圧し、金型４０に固定する。このとき、未硬化状態（仮キュア後を含む）の繊維強化プリプレグシートに屈曲部２８ａ，２８ｂを形成し、フレーム１８の形状に相当する形状に保持する。これにより、成形後の内部残留応力の発生を防止でき、強度の向上、安定化を図ることができる。金型４０に対する金型４２の加圧は、手で押圧する他、締付具あるいは押圧具を用いて行うことができる。   After the fiber reinforced prepreg is set in the mold 40, the fiber reinforced prepreg is pressurized with the upper mold 42 and fixed to the mold 40. At this time, the bent portions 28a and 28b are formed in the fiber-reinforced prepreg sheet in an uncured state (including after temporary curing) and held in a shape corresponding to the shape of the frame 18. Thereby, generation | occurrence | production of the internal residual stress after shaping | molding can be prevented, and a strength improvement and stabilization can be aimed at. The pressing of the mold 42 against the mold 40 can be performed by using a fastening tool or a pressing tool in addition to pressing by hand.

この後、繊維強化プリプレグシートを加熱硬化し、所定形状に成形した積層成形材３０として金型４０，４２から取り出す。   Thereafter, the fiber-reinforced prepreg sheet is heat-cured and taken out from the molds 40 and 42 as a laminated molding material 30 formed into a predetermined shape.

図５に示すように、金型４０，４２から取り出した積層成形材３０は、帯状の板状体４４として形成されており、フレーム１８に形成する部位を多数連ねた状態に形成される。この板状体４４は、長い帯状形状に限らず、例えばＴ字状またはＹ字状に形成したものであってもよい。また、フレーム１８を形成する部位を同じ方向に配置するだけでなく、交互に逆向きに配置し、または、複数部位をグループ状に配置することもできる。   As shown in FIG. 5, the laminated molding material 30 taken out from the molds 40 and 42 is formed as a band-like plate-like body 44, and is formed in a state in which a large number of parts to be formed on the frame 18 are connected. The plate-like body 44 is not limited to a long belt-like shape, and may be formed, for example, in a T shape or a Y shape. Moreover, not only the site | part which forms the flame | frame 18 is arrange | positioned in the same direction, but it can also arrange | position to a reverse direction alternately, or can also arrange several site | parts in group form.

フレーム１８は、例えばプレス加工、ウォータージェット等の流体の噴出による切出し、エンドミル等の刃具による切出し等の適宜の方法により、この板状体４４からそれぞれ切出し、加工することができる。この板状体４４からそれぞれのフレーム１８を加工する際に、釣糸案内部１４の貫通孔１４ａおよび支脚部１６の凹部１７を同時に加工することが好ましい。必要な場合には、フレーム１８を切出し加工した後に、貫通孔１４ａおよび凹部１６ｂ等の加工、更に、必要に応じて、細部の加工を行うことが好ましい。   The frame 18 can be cut out and processed from the plate-like body 44 by an appropriate method such as pressing, cutting out by ejecting fluid such as a water jet, or cutting out using a cutting tool such as an end mill. When each frame 18 is processed from the plate-like body 44, it is preferable that the through hole 14a of the fishing line guide portion 14 and the concave portion 17 of the support leg portion 16 are simultaneously processed. If necessary, after the frame 18 is cut out, it is preferable to process the through holes 14a and the recesses 16b and the like, and further, if necessary, to process details.

図６及び図７は、プリプレグシートからなる積層成形体３０に代え、多数の強化繊維を同じ方向に沿わせて束ねた束状、撚り合わせた撚り糸状、編込んだ編糸状又は互いに交差させて組紐状に形成した糸状体４６により、金型４８，５０を用いてフレーム１８を製造する製造工程の一部を示す。   6 and 7 are replaced with a laminated molded body 30 made of a prepreg sheet, a bundle of many reinforcing fibers bundled along the same direction, a twisted twisted yarn, a braided knitted yarn, or crossing each other. A part of a manufacturing process for manufacturing the frame 18 by using the molds 48 and 50 by the thread-like body 46 formed in a braid shape is shown.

図示の金型４８，５０は、その間に、フレーム１８を収容するキャビティ４８ａ，５０ａを形成する。このキャビティ４８ａ，５０ａは、フレーム１８の骨組み構造に沿った溝状に形成してあり、一方の金型からは、形成釣糸案内部１４の貫通孔１４ａ及び凹部１７を形成する部位に突出部５２ａ，５２ｂを形成してある。そして、一端が開口部５４を介して外部に開口し、糸状体４６の端部を金型４８，５０の外方に導出することができる。   The illustrated dies 48 and 50 form cavities 48a and 50a for accommodating the frame 18 therebetween. The cavities 48a and 50a are formed in a groove shape along the frame structure of the frame 18, and from one mold, a protruding portion 52a is formed at a portion where the through hole 14a and the concave portion 17 of the formed fishing line guide portion 14 are formed. , 52b are formed. One end is opened to the outside through the opening 54, and the end of the filament 46 can be led out of the molds 48 and 50.

この金型を用いてガイドリング１２とフレーム１４とを一体的に形成する場合は、上型５０と下型４８とを分離し、一方のキャビティ４８ａの全体を外部に開口させる。   When the guide ring 12 and the frame 14 are integrally formed using this mold, the upper mold 50 and the lower mold 48 are separated, and the entire one cavity 48a is opened to the outside.

図７に示すように、一方のキャビティ４８ａ内に糸状体４６を配置する。この際、繊維束を形成する糸条体を、キャビティ４８ａの溝方向に沿い、このキャビティ４８ａ内に所要の形状又はパターンで配置する。特に、固定側屈曲部２８ａを形成する固定側支脚領域１６ｃ及び支脚部側固定領域２４は、強化繊維量を多くするほか、中間部１６ｂよりも、合成樹脂比率（重量％）を多くし、肉厚を厚くし、又は、断面関を大きくすることにより、屈曲部２８ａにおける強化繊維の剥離や破損を防止することが好ましい。   As shown in FIG. 7, the thread-like body 46 is disposed in one cavity 48a. At this time, the yarn body forming the fiber bundle is arranged in a desired shape or pattern in the cavity 48a along the groove direction of the cavity 48a. In particular, the fixed side fulcrum region 16c and the fulcrum portion side fixed region 24 forming the fixed side bent portion 28a increase the amount of reinforcing fiber and increase the synthetic resin ratio (% by weight) more than the intermediate portion 16b. It is preferable to prevent peeling or breakage of the reinforcing fibers in the bent portion 28a by increasing the thickness or increasing the cross-sectional relationship.

この糸条体４６に合成樹脂を含浸しないで配置する場合は、所定のパターンを形成した後、閉じたキャビティ４８ａ，５０ａ内に合成樹脂を例えば圧入して充填する。合成樹脂を含浸した状態の糸状体４６を用いた場合には、このような合成樹脂の充填は必要ない。   In the case where the yarn body 46 is arranged without being impregnated with synthetic resin, after a predetermined pattern is formed, the synthetic resin is, for example, press-fitted into the closed cavities 48a and 50a and filled. When the thread-like body 46 impregnated with the synthetic resin is used, such filling of the synthetic resin is not necessary.

なお、このような糸状体４６で形成するフレーム１８は、補強又は剛性を向上するために、部分的に繊維強化プリプレグシートを配置してもよく、任意の材料を組合わせて使用することができる。特に、幅・厚さ・断面積のいずれかが変化する部分に、例えば所定形状に切断したプリプレグシート等の補助材料を配置してもよい。上述の積層成形体３０と糸状体４６とを組合わせて形成することもできる。   In addition, in the frame 18 formed of such a thread-like body 46, a fiber reinforced prepreg sheet may be partially disposed in order to reinforce or improve rigidity, and any material can be used in combination. . In particular, an auxiliary material such as a prepreg sheet cut into a predetermined shape may be disposed at a portion where any of the width, thickness, and cross-sectional area changes. It can also be formed by combining the laminated molded body 30 and the filamentous body 46 described above.

糸状体４６をキャビティ４８ａ，５０ａ内に配置した後、図４及び図５に示す工程と同様に、上型５０と下型４８とを重ね合わせ、加圧すると共に、キャビティ４８ａ，５０ａ内の材料の成形温度に加熱する。成形後、金型からフレーム１８を離型し、各フレーム１８の端部処理を行う。また、必要に応じて各フレーム１８からバリを除去する。   After the thread-like body 46 is disposed in the cavities 48a and 50a, the upper mold 50 and the lower mold 48 are overlapped and pressurized in the same manner as in the steps shown in FIGS. 4 and 5, and the material in the cavities 48a and 50a is pressed. Heat to molding temperature. After molding, the frame 18 is released from the mold, and the end portion of each frame 18 is processed. Further, burrs are removed from each frame 18 as necessary.

このように金型４０，４２又は金型４８，５０を用いて形成したフレーム１８に、必要な細部加工を終えた後、バレル研磨により、フレーム１８の表面のバリを除去すると共に、表面に光沢が得られる程度に仕上げ研磨する。この研磨の程度は、釣糸ガイド１０のサイズ、形状、材質等の特性に応じて調整し、必要な場合には研磨剤を用いる。特に、フレーム１８の表面の一部に強化繊維が露出し、マトリックス樹脂が一部残るように形成することにより、研磨表面の光沢を一層向上することができる。   The frame 18 formed by using the molds 40 and 42 or the molds 48 and 50 is finished with necessary fine processing, and then the burrs on the surface of the frame 18 are removed by barrel polishing and the surface is glossy. Finish polishing to the extent that can be obtained. The degree of this polishing is adjusted according to characteristics such as the size, shape and material of the fishing line guide 10, and an abrasive is used if necessary. In particular, the gloss of the polished surface can be further improved by forming the reinforcing fiber to be exposed on a part of the surface of the frame 18 and leaving a part of the matrix resin.

次に、必要に応じてフレームの全体又は一部に被膜を形成する。例えば、装飾を設けて外観を向上し、フレーム１８を保護するため、塗装してもよく、金属やセラミックスを蒸着することもできる。保持部１４の貫通孔１４ａの内周面に、耐磨耗性のセラミック材料、金属材料、合成樹脂材料等をコーティングし、このコーティング面を平滑に研磨した場合には、ガイドリング１２を別途取付けることを要しない。   Next, a film is formed on the whole or a part of the frame as necessary. For example, in order to improve the appearance by providing decoration and protect the frame 18, it may be painted, or metal or ceramics can be deposited. When the inner peripheral surface of the through hole 14a of the holding portion 14 is coated with a wear-resistant ceramic material, metal material, synthetic resin material, or the like, and the coated surface is polished smoothly, the guide ring 12 is separately attached. I don't need it.

このように形成したフレーム１８は、フレーム１８の幅、厚さ、断面形状、断面積などを適宜に形成することが容易であり、特に糸条体４６で形成することにより、設計自由度が高くなる。また、比強度、比剛性に優れ、強化繊維の特徴を効率的に活用した高性能の釣糸ガイド１０を形成することができる。   The frame 18 formed in this way can easily form the width, thickness, cross-sectional shape, cross-sectional area, etc. of the frame 18 as appropriate. Become. In addition, it is possible to form a high-performance fishing line guide 10 that is excellent in specific strength and specific rigidity and that efficiently utilizes the characteristics of reinforcing fibers.

図４に示す金型４０，４２、又は、図６に示す金型４８，５０を用いてフレーム１８を形成するいずれの場合も、支脚部１６の凹部１７で区画された最小繊維量部分である中間部１６ｂの強化繊維量よりも、固定側屈曲部２８ａを形成する固定側支脚部１６ｃ又は固定部の支脚部側固定部２４の強化繊維量を多くすることが好ましい。これにより、屈曲部２８ａの変形を抑制することができる。   In any case where the frame 18 is formed using the molds 40 and 42 shown in FIG. 4 or the molds 48 and 50 shown in FIG. 6, the minimum fiber amount portion defined by the recess 17 of the support leg portion 16. It is preferable to increase the amount of reinforcing fiber of the fixed side support leg portion 16c forming the fixed side bent portion 28a or the support leg side fixing portion 24 of the fixed portion, rather than the amount of reinforcing fiber of the intermediate portion 16b. Thereby, the deformation | transformation of the bending part 28a can be suppressed.

支脚部側固定部２４の合成樹脂比率（重量％）は、支脚部１６よりも多くすることが好ましいが、繊維量が多い場合には、合成樹脂量の比率を少なくすることで、調整することができる。   The synthetic resin ratio (% by weight) of the supporting leg side fixing part 24 is preferably larger than that of the supporting leg part 16, but when the fiber amount is large, the synthetic resin ratio is adjusted by reducing the ratio of the synthetic resin amount. Can do.

更に、支脚部１６が複数本に分かれている場合にあｈ、これらの複数の支脚部の全体を合計した断面積よりも大きくすることが好ましい。   Further, when the support leg portion 16 is divided into a plurality of pieces, it is preferable that the cross-sectional area is greater than the total of the plurality of support leg portions.

このように、支脚部側固定部２４の強化繊維量を多くすること、合成樹脂比率を多くすること、肉厚を厚くすること、断面積を大きくすることの４つの条件のうちの１つ、又は２以上を組合わせて形成することにより、屈曲部２８ａにおける強化繊維の剥離や破損を防止することができる。   Thus, one of the four conditions of increasing the reinforcing fiber amount of the support leg side fixing portion 24, increasing the synthetic resin ratio, increasing the thickness, and increasing the cross-sectional area, Alternatively, by forming a combination of two or more, it is possible to prevent peeling or breakage of the reinforcing fibers in the bent portion 28a.

また、支脚側固定部２４から、固定部側支脚部１６ｃにかけて補強層を形成してもよく、これにより、屈曲部２８ａにおける強化繊維の剥離や破損を防止することができる。   In addition, a reinforcing layer may be formed from the support leg side fixing part 24 to the fixing part side support leg part 16c, thereby preventing peeling or breakage of the reinforcing fiber in the bent part 28a.

図８から図１１は、このようなフレーム１８の固定部２０における支脚部側領域２４と低弾性領域２６との具体的な形態を示す。   FIGS. 8 to 11 show specific forms of the support leg side region 24 and the low elasticity region 26 in the fixing portion 20 of the frame 18.

図８に示すフレーム１８は、少なくとも固定側屈曲部２８ａを形成する固定部２０の支脚部側領域２４と、支脚部１６の固定側領域１６ｃとは、この屈曲部２８ａでフレーム１８を形成する繊維強化樹脂中の強化繊維５６がこの屈曲部２８ａで連続している。固定側領域１６ｃと支脚部側領域２４とで強化繊維５６がこの屈曲部２８ａで連続し、その剛性がほぼ等しく形成されることにより、固定側屈曲部２８ａが変形し難く、フレーム１８に外力が作用した場合でも、釣糸案内部１４の貫通孔１４ａを所要の方向に安定した状態で維持し、支えることができる。   In the frame 18 shown in FIG. 8, at least the support leg part region 24 of the fixing part 20 forming the fixed side bent part 28a and the fixed side area 16c of the support leg part 16 are fibers forming the frame 18 by the bent part 28a. The reinforcing fiber 56 in the reinforced resin is continuous at the bent portion 28a. The reinforcing fiber 56 is continuous at the bent portion 28a in the fixed side region 16c and the support leg side region 24, and the rigidity thereof is formed to be substantially equal, so that the fixed side bent portion 28a is hardly deformed, and external force is applied to the frame 18. Even when it acts, the through hole 14a of the fishing line guide portion 14 can be maintained and supported in a stable state in a required direction.

これらの強化繊維５６は、一部を低剛性領域２６で断絶してある。このような低剛性領域２６は、固定部２０の全長の半分以上にわたって形成される。これにより、低剛性領域２６は、支脚部側領域２４に比して剛性が小さくなり、支脚部１６が釣糸案内部１４の姿勢を確実に保持しつつ竿管８の撓りに追従して撓うことができる。   Some of these reinforcing fibers 56 are cut off at the low rigidity region 26. Such a low rigidity region 26 is formed over half or more of the entire length of the fixed portion 20. As a result, the low-rigidity region 26 is less rigid than the support leg side region 24, and the support leg portion 16 flexes following the bending of the rod pipe 8 while reliably holding the posture of the fishing line guide portion 14. I can.

通常、釣糸ガイドは、固定部を竿管に糸巻固定した上から、糸止剤（エポキシ、ウレタン等）をコーティングして糸止めしており、固定部の剛性が高い場合には、固定部の端部位置で糸止剤にクラックが発生する場合があり、また、釣糸ガイドを下向きにして使用した際に、このような釣糸ガイドの剛性が高いと、固定部の先端部に応力が集中して竿管にクラックが入り、破損しやすくなる場合がある。固定部２０の自由端側がこのように、低剛性に形成されることにより、釣竿の竿管８は、撓り性が阻害されることなく、このようなクラックの発生も防止される。   Usually, the fishing line guide is fixed to the rod with a bobbin and then threaded with a thread stopper (epoxy, urethane, etc.). If the rigidity of the fixing part is high, Cracks may occur in the thread stopper at the end position, and when the fishing line guide is used facing downward, if the fishing line guide has high rigidity, stress concentrates on the tip of the fixed part. This may cause cracks in the soot tube and easily break. By forming the free end side of the fixing portion 20 in such a low rigidity in this manner, the fishing rod 8 of the fishing rod is not hindered from bending, and the occurrence of such cracks is also prevented.

図８に示す固定部２０は、表面側に配置された強化繊維５６が低剛性領域２６の傾斜状部２６ａで切断され、更に、薄肉化領域２６ｃで切断されている。これにより、図１に示すように、傾斜状部２６ａは、厚さｔ２の支脚部側領域２４から厚さｔ１の中間部２６ｂまで厚さが変化する。この傾斜状部２６ａは、中間部２６ｂの表面に対して垂直な面を形成する状態に切断してもよく、複数の段部を形成してもよい。また、薄肉化部２６ｃは、厚さｔ１の中間部２６ｂの表面を、裏面２２に接続する。この薄肉化部２６ｃの表面は平坦な傾斜面を形成してもよく、外方の膨出した湾曲面で形成してもよい。   In the fixing portion 20 shown in FIG. 8, the reinforcing fibers 56 arranged on the surface side are cut by the inclined portion 26a of the low-rigid region 26 and further cut by the thinned region 26c. Thereby, as shown in FIG. 1, the thickness of the inclined portion 26a changes from the support leg side region 24 having the thickness t2 to the intermediate portion 26b having the thickness t1. The inclined portion 26a may be cut to form a surface perpendicular to the surface of the intermediate portion 26b, or a plurality of step portions may be formed. The thinned portion 26c connects the surface of the intermediate portion 26b having the thickness t1 to the back surface 22. The surface of the thinned portion 26c may be formed with a flat inclined surface or an outwardly bulging curved surface.

更に、傾斜状部２６ａと中間部２６ｂと薄肉化部２６ｃとが１つの平坦な傾斜面又は滑らかに湾曲した湾曲面により、テーパ状に形成してもよい。この場合には、竿管８の撓り性が阻害されることなく、糸止剤や竿管のクラックの発生も防止されることに加え、更に、糸巻等による固定を容易に行うことができる。   Furthermore, the inclined portion 26a, the intermediate portion 26b, and the thinned portion 26c may be formed in a tapered shape by one flat inclined surface or a smoothly curved curved surface. In this case, in addition to preventing the occurrence of cracks in the thread stopper and the rod tube without hindering the flexibility of the rod tube 8, it can be easily fixed by a spool or the like. .

なお、このように支脚側固定部２４と連続する強化繊維を切断する部位は、図８に示すような、固定部２０の表面側に限らず、裏面２２側、又は裏面２２と表面との間の部位であってもよい。   In addition, the site | part which cut | disconnects the reinforcement fiber continuous with the fulcrum side fixing | fixed part 24 in this way is not restricted to the surface side of the fixing | fixed part 20 as shown in FIG. 8, but the back surface 22 side or between the back surface 22 and the surface. It may be the site of.

図９は、裏面２２側で強化繊維５６を切断したもので、ここでは、中間領域２６ｂ内の３箇所にカット部５８を形成することにより、低弾性領域２６における撓み性を向上させてある。なお、カット部５８は３箇所に限るものではないが、裏面２２側に複数箇所に設けることにより、竿管８に固定したときの安定性が増大し、竿管８から脱落し難くなる。   FIG. 9 is a diagram in which the reinforcing fiber 56 is cut on the back surface 22 side. Here, the flexibility in the low elastic region 26 is improved by forming cut portions 58 at three locations in the intermediate region 26b. In addition, although the cut part 58 is not restricted to three places, by providing in multiple places in the back surface 22 side, stability when it fixes to the soot pipe 8 will increase, and it will become difficult to drop out from the soot pipe 8.

図１０は、固定部２０が、裏面２２側に低弾性率の強化繊維を配置した低弾性層６０と、表面側に弾性率の強化繊維を配置した高弾性層６２とを積層して形成されている。これらの低弾性層６０及び高弾性層６２内の強化繊維は、支脚部１６の固定側領域１６ｃと連続している。   In FIG. 10, the fixing portion 20 is formed by laminating a low elastic layer 60 in which reinforcing fibers having low elastic modulus are arranged on the back surface 22 side and a high elastic layer 62 in which reinforcing fibers having elastic modulus are arranged on the front surface side. ing. The reinforcing fibers in the low elastic layer 60 and the high elastic layer 62 are continuous with the fixed side region 16 c of the support leg 16.

低弾性領域２６は、高弾性層６２を削って形成してあり、図示の実施形態では、傾斜状部２６ａで高弾性層６２をカットしてある。中間部２６ｂ及び薄肉化部２６ｃには高弾性層６２が配置されていない。これにより、低弾性領域２６が支脚側固定部２４よりも低弾性に形成され、竿管８の撓り性が阻害されるのを防止する。   The low elastic region 26 is formed by cutting the high elastic layer 62. In the illustrated embodiment, the high elastic layer 62 is cut by the inclined portion 26a. The high elastic layer 62 is not disposed in the intermediate portion 26b and the thinned portion 26c. Thereby, the low elasticity area | region 26 is formed in a lower elasticity than the support leg side fixing | fixed part 24, and it prevents that the flexibility of the soot tube 8 is inhibited.

なお、低弾性層６０の強化繊維が高弾性層６２の強化繊維と実質的に同じ弾性率を有する場合には、固定部２０の長手方向に対して１０度〜６０度、好ましくは１５度〜４５度の角度で配向させた強化繊維を主体として低弾性層６０を形成することもできる。この場合には、高弾性層６２の全体を切削することは必要なく、一部のみ切削し、又は、支脚部側領域２４の厚さｔ２と低弾性領域の中間部２６ｂの厚さｔ１とをほぼ等しく形成することも可能である。なお、主体とは、弾性率に影響を与える程度に含まれることをいう。   When the reinforcing fiber of the low elastic layer 60 has substantially the same elastic modulus as the reinforcing fiber of the high elastic layer 62, it is 10 degrees to 60 degrees, preferably 15 degrees to the longitudinal direction of the fixed portion 20. The low elastic layer 60 can also be formed mainly of reinforcing fibers oriented at an angle of 45 degrees. In this case, it is not necessary to cut the entire high elastic layer 62, and only a part of the high elastic layer 62 is cut. Alternatively, the thickness t2 of the support leg side region 24 and the thickness t1 of the intermediate portion 26b of the low elastic region are set. It is also possible to form approximately the same. In addition, a main body means being contained to the extent which affects an elasticity modulus.

図１１は、釣糸ガイドのフレーム１８を竿管８の表面上に配置したときの固定部２０の各部の関係を示す。   FIG. 11 shows the relationship between each part of the fixing part 20 when the frame 18 of the fishing line guide is arranged on the surface of the rod 8.

固定部２０の全長をｋ１、支脚側固定領域２４の長さをｋ２、低弾性領域２６の長さをｋ３で示してある。また、ｋ４は傾斜部２６ａの長さ、ｋ５は中間部の長さ、ｋ６は薄肉化部２６ｃの長さであり、ｗは幅である。   The total length of the fixing portion 20 is indicated by k1, the length of the support leg side fixing region 24 is indicated by k2, and the length of the low elastic region 26 is indicated by k3. Further, k4 is the length of the inclined portion 26a, k5 is the length of the intermediate portion, k6 is the length of the thinned portion 26c, and w is the width.

固定部２０の幅ｗは、支脚部側領域２４から低弾性領域２６の大部分の領域までほぼ等しく形成し、薄肉化部２６ｃよりも支脚部１６側に位置する部位から、自由端に向けて次第に狭めて形成してある。これにより、固定部２０の長い範囲で広い面積の載置面を確保することができる。幅ｗがほぼ一定の領域は、支脚部１６側から、ｋ１の半分以上の長さにわたって延びることが好ましい。   The width w of the fixing portion 20 is formed to be substantially equal from the support leg side region 24 to most of the low elastic region 26, and from the portion located closer to the support leg 16 side than the thinned portion 26c toward the free end. It is gradually narrowed. Thereby, a mounting surface having a wide area can be secured in the long range of the fixing portion 20. The region where the width w is substantially constant preferably extends from the support leg portion 16 side over a length of half or more of k1.

長さｋ３が、長さｋ１の１／３〜１／４の範囲に形成したときに、低弾性領域の曲げ剛性を、支脚部側領域２４の曲げ剛性の６０〜２０％、好ましくは５０〜３０％に形成することで、屈曲部２８ａの角度α１を維持しつつ、竿管８の撓り性を阻害しない程度の撓り性を固定部２０に確保することができる。   When the length k3 is formed in the range of 1/3 to 1/4 of the length k1, the bending stiffness of the low elastic region is 60 to 20% of the bending stiffness of the support leg side region 24, preferably 50 to 50%. By forming it at 30%, it is possible to ensure the flexibility of the fixed portion 20 to the extent that the flexibility of the soot tube 8 is not impaired while maintaining the angle α1 of the bent portion 28a.

傾斜部２６ａの長さｋ４は、中間部ｋ５より短く、図８に示す実施形態のように、切断状態によっては、実質的に０になることもあり、薄肉化部２６ｃの長さｋ６は、糸巻固定の容易性から固定部の長さｋ１の５〜１０％程度の範囲とすることが好ましい。   The length k4 of the inclined portion 26a is shorter than the intermediate portion k5 and may be substantially 0 depending on the cut state as in the embodiment shown in FIG. 8, and the length k6 of the thinned portion 26c is In view of ease of pincushion fixation, it is preferable that the length be in the range of about 5 to 10% of the length k1 of the fixing part.

この支脚部側領域２４の長さｋ２は、屈曲部２８ａの角度α１を維持できるものであればよく、ｋ１の２０〜４０％程度が好ましい。 The length k2 of the support leg side region 24 may be any length as long as the angle α1 of the bent portion 28a can be maintained, and is preferably about 20 to 40% of k1.

なお、固定部２０の全体を同質の繊維強化樹脂で形成した場合には、長さｋ３を長さｋ１の１／３〜１／４の範囲にしたときに、低弾性領域２６の平均厚さ又は中間部２６ｂにおける厚さｔ１が、支脚部側領域２４の厚さｔ２の８０〜３０％程度で、特に、６０〜４０％に形成することにより、釣糸ガイド１０は固定部２０を介して竿管８に確実に保持されると共に、竿管８の撓り性を阻害することなく、糸止部や竿管のクラックの発生も確実に防止することができる。   In addition, when the whole fixing | fixed part 20 is formed with the fiber reinforced resin of the same quality, when length k3 is made into the range of 1/3-1/4 of length k1, the average thickness of the low elastic area | region 26 is shown. Alternatively, when the thickness t1 of the intermediate portion 26b is about 80 to 30% of the thickness t2 of the support leg side region 24, in particular, 60 to 40%, the fishing line guide 10 can be While being securely held by the pipe 8, it is possible to reliably prevent the yarn stopper and the crack from being cracked without impairing the flexibility of the pipe 8.

このように、固定部２０が支脚部側固定領域２４よりも剛性の小さい低剛性領域２６を自由端側に有し、この低剛性領域２６を固定部２０の全長ｋ１の半分以上の長さｔ３にわたって形成することにより、竿管８の撓り性が阻害されることなく、糸止部や竿管のクラックの発生も防止される。   As described above, the fixed portion 20 has the low rigidity region 26 whose rigidity is smaller than that of the support leg side fixed region 24 on the free end side, and this low rigidity region 26 has a length t3 that is more than half of the total length k1 of the fixed portion 20. By forming over, the flexibility of the tub tube 8 is not hindered, and the occurrence of cracks in the thread stop and the tub tube is also prevented.

以上、種々の釣糸ガイドのフレーム１８について説明したが、いずれかの形態に限定されるものではなく、種々の組合せが可能なことは明らかである。例えば積層成形材３０と糸条体４６とを組合わせてフレーム１８を形成することも可能である。また、繊維強化樹脂は、シート状、テープ状、糸条体等の任意の形態で使用でき、必要に応じて種々組合わせることもできる。更に、固定部２０は、フレーム１８に対して一方方向に延びる片足タイプの釣糸ガイド釣糸ガイドに限らず、竿管の前方及び後方の両方向に延びる形式の釣糸ガイドにも適用可能である。   Although various types of fishing line guide frames 18 have been described above, the present invention is not limited to any form, and it is obvious that various combinations are possible. For example, the frame 18 can be formed by combining the laminated molding material 30 and the thread body 46. Moreover, fiber reinforced resin can be used with arbitrary forms, such as a sheet form, a tape form, a thread body, and can also be combined variously as needed. Further, the fixing portion 20 is not limited to a one-leg type fishing line guide that extends in one direction with respect to the frame 18 but can be applied to a fishing line guide that extends in both the front and rear directions of the rod.
