Description

本発明は、継合部材、及びこれを備えた釣竿に関する。 The present invention relates to a joint member and a fishing rod equipped with the same.

従来より、竿体（先節）と竿体（元節）との間に継ぎ部を設けた様々な釣竿が知られている。 Conventionally, various fishing rods are known that have a joint between the rod body (tip section) and the rod body (base section).

このような釣竿として、例えば、特許文献１には、複数に分離されているそれぞれの竿を連結管の両端に接続して組み立てられる中通し竿であって、当該連結管には、釣糸を当該中通し竿外から竿内に導入するガイド管を捩じ込む傾斜穴が前記連結管の側面から一方の竿の中空部に連通するように形成されると共に、当該傾斜穴の内壁面には、当該ガイド管の外周部に形成された雄ねじ部と螺合する雌ねじ部が形成され、前記ガイド管は、その両端に釣糸ガイドリングを保持させた状態で前記連結管の傾斜穴に装着されていることを特徴とする中通し竿が開示されている。 For example, Patent Document 1 discloses such a fishing rod, which is a through-rod assembled by connecting each of the multiple separate rods to both ends of a connecting tube, in which an inclined hole is formed from the side of the connecting tube to connect to the hollow part of one of the rods, into which a guide tube is screwed to introduce the fishing line into the rod from outside the through-rod, and the inner wall surface of the inclined hole is formed with a female thread that screws into a male thread formed on the outer periphery of the guide tube, and the guide tube is attached to the inclined hole of the connecting tube with fishing line guide rings held on both ends.

また、特許文献２には、釣竿の接合部において、円錐状に成型された挿入部と、前記円錐状の挿入部の中心を通る軸と、中空構造の内部が円錐状に掘削された受け口を有するティップ部、もしくは、ベリー部を接合し、接合部の接着表面積を広げ、応力分散と、強度を向上することで、接合部の全長を短くすることが可能となり、自然な釣竿の曲がりを実現することが開示されている。 Patent Document 2 also discloses that at the joint of a fishing rod, a conically molded insert section, an axis passing through the center of the conical insert section, and a tip section or belly section having a hollow structure with a conically excavated receiving opening inside are joined, increasing the adhesive surface area of the joint, improving stress dispersion and strength, thereby making it possible to shorten the overall length of the joint and achieving a natural bending of the fishing rod.

しかしながら、いずれの特許文献に開示の釣竿においても、先節と元節が着脱可能に構成されているものの、これらを継合する継合部の寸法や形状に合わせた先節と元節の使用がそもそも前提となるため、先節と元節の寸法や形状には自ずと制約が課され、複数の先節と元節とを交換可能に構成しても、事実上交換自由度が著しく低減されてしまうという問題があった。 However, in the fishing rods disclosed in all of the patent documents, although the tip and base sections are configured to be detachable, the use of a tip and base section that match the dimensions and shape of the joint that joins them is a prerequisite, so there are naturally restrictions on the dimensions and shape of the tip and base sections, and even if multiple tip and base sections are configured to be interchangeable, there is a problem in that the freedom to replace them is effectively significantly reduced.

本発明は上記の事情に鑑みてなされたものであり、その目的とするところは、元節と先節のいずれも着脱可能としながら、様々な寸法及び形状の元節と先節を継合可能とすることで、元節と先節を柔軟に選択可能とし、釣竿の使用者の種々異なる様々な要求に応えることを可能とする継合部材及びこれを備えた釣竿を提供することにある。本発明のこれら以外の目的は、本明細書全体を参照することにより明らかとなる。 The present invention was made in consideration of the above circumstances, and its purpose is to provide a joint member and a fishing rod equipped with the same that allows for flexible selection of the base section and tip section by allowing the base section and tip section to be joined together in various sizes and shapes while allowing both the base section and tip section to be detached, thereby making it possible to meet the various and varied needs of fishing rod users. Other objects of the present invention will become clear by referring to this specification as a whole.

以下、本発明に係る釣竿の実施形態について、添付図面を参照しながら具体的に説明する。複数の図面において共通する構成要素には当該複数の図面を通じて同一の参照符号が付されている。各図面は、説明の便宜上、必ずしも正確な縮尺で記載されているとは限らない点に留意されたい。 Embodiments of a fishing rod according to the present invention will be described in detail below with reference to the attached drawings. Components common to multiple drawings are given the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for ease of explanation.

図１は、本発明に係る釣竿の一実施形態を示す図である。図示のように、本発明の一実施形態による釣竿１は、竿体２と、竿体２にリールシート９を介して取り付けられたリール６と、竿体２に取り付けられた釣糸ガイド１０と、を備える。図示の実施形態においては、リールシート９及び釣糸ガイド１０の各々が、竿体の外周面に取り付けられる取付部品に該当する。 Figure 1 shows one embodiment of a fishing rod according to the present invention. As shown, the fishing rod 1 according to one embodiment of the present invention comprises a rod body 2, a reel 6 attached to the rod body 2 via a reel seat 9, and a fishing line guide 10 attached to the rod body 2. In the illustrated embodiment, each of the reel seat 9 and the fishing line guide 10 corresponds to an attachment part that is attached to the outer circumferential surface of the rod body.

竿体２は、例えば、元竿３、中竿５、及び穂先竿７等を連結することによって構成されている。これらの各竿体は、例えば、並継ぎ式に継合される。元竿３、中竿５、及び穂先竿７は、振出方式、逆並継方式、インロー方式、又はこれら以外の公知の任意の継合方式により継合され得る。竿体２は、単一の竿体から構成されていてもよい。 The rod body 2 is formed by connecting, for example, a base rod 3, a middle rod 5, and a tip rod 7. These rod bodies are joined, for example, in a parallel joint. The base rod 3, middle rod 5, and tip rod 7 can be joined by a telescoping method, a reverse parallel joint method, a spigot joint method, or any other known joining method. The rod body 2 may be formed from a single rod body.

元竿３、中竿５、及び穂先竿７は、例えば、繊維強化樹脂製の管状体で構成されている。この繊維強化樹脂製の管状体は、強化繊維にマトリクス樹脂を含浸させた繊維強化樹脂プリプレグ（プリプレグシート）を芯金に巻回し、このプリプレグシートを加熱して硬化させることにより作成される。このプリプレグシートに含まれる強化繊維として、例えば、炭素繊維、ガラス繊維、及びこれら以外の任意の公知の強化繊維を用いることができる。当該プリプレグシートに含まれるマトリクス樹脂として、エポキシ樹脂等の熱硬化性樹脂を用いることができる。プリプレグシートが硬化された後には、芯金が脱芯される。また、管状体の外表面は、適宜研磨される。各竿体は、中実状に構成されてもよい。 The base rod 3, middle rod 5, and tip rod 7 are each made of a tubular body made of fiber-reinforced resin, for example. This fiber-reinforced resin tubular body is made by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core bar, and then heating and curing the prepreg sheet. The reinforcing fibers contained in the prepreg sheet can be, for example, carbon fiber, glass fiber, or any other known reinforcing fiber. The matrix resin contained in the prepreg sheet can be a thermosetting resin such as epoxy resin. After the prepreg sheet has cured, the core bar is de-cored. The outer surface of the tubular body is polished as appropriate. Each rod body may be made solid.

図示の実施形態において、元竿３、中竿５及び穂先竿７には、リールシート９に装着されるリール６から繰り出される釣糸を案内する複数の釣糸ガイド１０（釣糸ガイド１０Ａ～１０Ｄ）が設けられている。より具体的には、元竿３には釣糸ガイド１０Ａが設けられ、中竿５には釣糸ガイド１０Ｂが設けられ、穂先竿７には釣糸ガイド１０Ｃが設けられている。穂先竿７の先端には、トップガイド１０Ｄが設けられているが、詳細は省略する。 In the illustrated embodiment, the butt rod 3, middle rod 5, and tip rod 7 are provided with multiple line guides 10 (line guides 10A-10D) that guide the fishing line that is let out from the reel 6 attached to the reel seat 9. More specifically, the butt rod 3 is provided with line guide 10A, the middle rod 5 is provided with line guide 10B, and the tip rod 7 is provided with line guide 10C. A top guide 10D is provided at the tip of the tip rod 7, but details will be omitted.

穂先竿７と、中竿５との間には、後述する継合部材４（継合部品又は継合構造ともいう）が設けられ、穂先竿７と、中竿５は、継合部材４に着脱可能に取付けられ、後述するように種々の形状や寸法の穂先竿７及び中竿５が取付け可能にされる。以降、穂先竿７を、前側の竿体又は先節とし、中竿５を、後ろ側の竿体又は元節とする。また、後ろ側の竿体又は元節とする場合、中竿５及び元竿３のいずれも含めることができる。 Between the tip rod 7 and the middle rod 5, a joint member 4 (also called a joint part or joint structure) is provided, which will be described later. The tip rod 7 and the middle rod 5 are removably attached to the joint member 4, allowing tip rods 7 and middle rods 5 of various shapes and sizes to be attached, as will be described later. Hereinafter, the tip rod 7 will be referred to as the front rod body or tip section, and the middle rod 5 will be referred to as the rear rod body or base section. In addition, when referring to the rear rod body or base section, both the middle rod 5 and the base rod 3 can be included.

次に、リールシート９について簡単に説明する。リールシート９は、魚釣用リール６のリール脚（図示しない）が載置されるリール脚載置面（リール脚載置部）をその軸方向に沿って有するリールシート本体を備えている。リールシート本体は、全体として筒状に形成されている。また、リールシート本体は、合成樹脂（例えばポリアミド系合成繊維やＡＢＳ樹脂等）あるいは金属（例えばＳＵＳ、アルミニウム、チタン、真鍮等）等の適宜の材料から形成されている。リールシート本体は、例えば、６０－１６０ｍｍの長さを有するよう構成できるが、これに限られない。また、このリールシート本体は、リール脚載置面の反対側を僅かに膨出させ、握持する手で握り込んだときに、母指球またはその近部を支えることで握持し易い湾曲形状の外面を有する握り部を形成してある。 Next, the reel seat 9 will be briefly described. The reel seat 9 has a reel seat body having a reel leg mounting surface (reel leg mounting portion) along its axial direction on which the reel legs (not shown) of the fishing reel 6 are placed. The reel seat body is formed into a cylindrical shape as a whole. The reel seat body is formed from an appropriate material such as synthetic resin (e.g., polyamide synthetic fiber or ABS resin) or metal (e.g., SUS, aluminum, titanium, brass, etc.). The reel seat body can be configured to have a length of, for example, 60-160 mm, but is not limited to this. The reel seat body also has a grip portion with a curved outer surface that bulges slightly on the side opposite the reel leg mounting surface and supports the ball of the foot or the area near it when gripped by the gripping hand, making it easy to grip.

リールシート本体のリール脚載置面は、平坦または、リールシート本体のリール脚載置面に隣接する他の周方向の部位（例えば握り部）よりも大きな曲率をもって略平坦に形成することができ、かつ、リールシート本体の軸方向に延びた状態に形成されている。リールシート本体には、一端（竿元側）に固定フードが一体的に配設されている。リールシート本体のリール脚載置面の一端は、固定フードの内部に配設されている。 The reel leg mounting surface of the reel seat body can be formed flat or approximately flat with a greater curvature than other circumferential portions (e.g., the grip portion) adjacent to the reel leg mounting surface of the reel seat body, and is formed to extend in the axial direction of the reel seat body. A fixed hood is integrally disposed at one end (rod base side) of the reel seat body. One end of the reel leg mounting surface of the reel seat body is disposed inside the fixed hood.

次に、図２－８を参照して、本発明の一実施形態に係る継合部材について説明する。まず、図２－５に示すように、本発明の一実施形態に係る継合部材４は、釣竿１の前側の竿体１１と後側の竿体１２とが着脱可能にされる継合部材４であって、筒状に形成され、該前側の竿体１１が取付け可能な第１の継合部１３と、筒状に形成され、該後側の竿体１２が取付け可能な第２の継合部１４と、これらを接続する中央部１５と、を備え、該前側の竿体１１は、該第１の継合部の内面（図２、３の場合であり、並継合せともいう）又は外面（図４、５の場合であり、逆並継合せともいう）に取付け可能にされ、該後側の竿体１２は、該第２の継合部の内面（図２、４の場合であり、逆並継合せともいう）又は外面（図３、５の場合であり、並継合せともいう）に取付け可能にされ、該後側の竿体は、該第２の継合部の内面又は外面に取付け可能にされる。また、中央部１５は、中空部１６を備え、第１の継合部１３から第２の継合部１４へ向けて、内径は同じ（ここで、「同じ」とは、数学的に同じ場合だけでなく、略同じ場合、すなわち、前後反転して使用しても、それほど大きな差異が無い程度（例えば、第１の継合部１３側と、第２の継合部１４側との内径差の発生の可能性に鑑み、±０．０４ｍｍ程度の内径差）までも含むこととするが、外径はその中央部分が隆起するように形成されている。本態様では、前側の竿体と後側の竿体とで、その外径ないし内径が同じ若しくは異なるものであって、後述する図６の態様に比してそれ程大きな差異がない場合において、これらを取付ける場合が想定される。 Next, referring to Figures 2-8, we will explain the joining member according to one embodiment of the present invention. First, as shown in FIG. 2-5, the joint member 4 according to one embodiment of the present invention is a joint member 4 that allows the front rod body 11 and the rear rod body 12 of the fishing rod 1 to be detachably attached, and includes a first joint portion 13 formed in a cylindrical shape to which the front rod body 11 can be attached, a second joint portion 14 formed in a cylindrical shape to which the rear rod body 12 can be attached, and a central portion 15 that connects these. The front rod body 11 can be attached to the inner surface (in the case of FIG. 2 and 3, also called a parallel joint) or the outer surface (in the case of FIG. 4 and 5, also called a reverse parallel joint) of the first joint portion, and the rear rod body 12 can be attached to the inner surface (in the case of FIG. 2 and 4, also called a reverse parallel joint) or the outer surface (in the case of FIG. 3 and 5, also called a parallel joint) of the second joint portion, and the rear rod body can be attached to the inner surface or the outer surface of the second joint portion. The central portion 15 also has a hollow portion 16, and the inner diameter is the same from the first joint 13 to the second joint 14 (here, "same" does not only mean mathematically the same, but also means that it is approximately the same, i.e., even if it is used in reverse front and back, there is not much difference (for example, an inner diameter difference of about ±0.04 mm in consideration of the possibility of an inner diameter difference between the first joint 13 side and the second joint 14 side), but the outer diameter is formed so that the center part is raised. In this embodiment, the outer diameter or inner diameter of the front rod body and the rear rod body are the same or different, and it is assumed that they will be attached when there is not much difference compared to the embodiment in Figure 6 described later.

本発明の一実施形態に係る継合部材によれば、元節と先節のいずれも着脱可能としながら、様々な寸法及び形状の元節と先節を継合可能とすることで、元節と先節を柔軟に選択可能とし、釣竿の使用者の種々異なる様々な要求に応えることを可能とする継合部材を提供することが可能となる。 The joint member according to one embodiment of the present invention allows the base section and tip section to be attached and detached, while allowing the base section and tip section to be joined in a variety of sizes and shapes, allowing for flexible selection of base section and tip section, and making it possible to provide a joint member that can meet the various and varied needs of fishing rod users.

次に、図６を参照して、本発明の一実施形態に係る継合部材４について説明する。図示のように、本発明の一実施形態に係る継合部材４は、釣竿１の前側の竿体（図示しない）と後側の竿体（図示しない）とが着脱可能にされる継合部材４であって、筒状に形成され、該前側の竿体が取付け可能な第１の継合部１３と、筒状に形成され、該後側の竿体が取付け可能な第２の継合部１４と、これらを接続する中央部１５と、を備える。また、該前側の竿体は、該第１の継合部１３の内面又は外面に取付け可能にされ、該後側の竿体は、該第２の継合部１４の内面又は外面に取付け可能にされる。また、中央部１５は、中空部１６を備え、第１の継合部１３から第２の継合部１４へ向けて、内径及び外径ともに大きくなるように形成されている。本態様では、図２の態様に比して、前側の竿体と後側の竿体との外径ないし内径がより大きく異なるものを取付けることが想定される。 Next, referring to FIG. 6, the joint member 4 according to one embodiment of the present invention will be described. As shown in the figure, the joint member 4 according to one embodiment of the present invention is a joint member 4 that allows the front rod body (not shown) and the rear rod body (not shown) of the fishing rod 1 to be detachable, and includes a first joint portion 13 formed in a cylindrical shape to which the front rod body can be attached, a second joint portion 14 formed in a cylindrical shape to which the rear rod body can be attached, and a central portion 15 that connects them. The front rod body can be attached to the inner or outer surface of the first joint portion 13, and the rear rod body can be attached to the inner or outer surface of the second joint portion 14. The central portion 15 includes a hollow portion 16, and is formed so that both the inner diameter and the outer diameter become larger from the first joint portion 13 to the second joint portion 14. In this embodiment, it is expected that the outer and inner diameters of the front and rear rod bodies will be significantly different from each other compared to the embodiment shown in FIG. 2.

次に、図７を参照して、本発明の一実施形態に係る継合部材４について説明する。図示のように、本発明の一実施形態に係る継合部材４は、釣竿１の前側の竿体（図示しない）と後側の竿体（図示しない）とが着脱可能にされる継合部材４であって、筒状に形成され、該前側の竿体１１が取付け可能な第１の継合部１３と、筒状に形成され、該後側の竿体１２が取付け可能な第２の継合部１４と、これらを接続する中央部１５と、を備える。また、該前側の竿体１１は、該第１の継合部１３の内面に取付け可能にされ、該後側の竿体１２も、該第２の継合部１４の内面に取付け可能にされる。また、中央部１５は、中空部１６を備え、第１の継合部１３から第２の継合部１４へ向けて、内径及び外径ともに大きくなるように形成されている。本態様では、継合部材が竿先から竿元にかけて剛性が高くなるように形成されることで、しなやかかつ感度良好な先節と操作性がよくしっかりした元節との間を、継ぎ目の少ない繋がりが良好な継合部として形成することが可能となる。 Next, referring to FIG. 7, the joint member 4 according to one embodiment of the present invention will be described. As shown in the figure, the joint member 4 according to one embodiment of the present invention is a joint member 4 that allows the front rod body (not shown) and the rear rod body (not shown) of the fishing rod 1 to be detachably attached, and includes a first joint portion 13 formed in a cylindrical shape to which the front rod body 11 can be attached, a second joint portion 14 formed in a cylindrical shape to which the rear rod body 12 can be attached, and a central portion 15 that connects them. The front rod body 11 can be attached to the inner surface of the first joint portion 13, and the rear rod body 12 can also be attached to the inner surface of the second joint portion 14. The central portion 15 includes a hollow portion 16, and is formed so that both the inner diameter and the outer diameter become larger from the first joint portion 13 to the second joint portion 14. In this embodiment, the joint member is formed so that its rigidity increases from the tip to the base of the rod, making it possible to form a good joint with few seams between the flexible and sensitive tip section and the sturdy butt section with good operability.

次に、図８を参照して、本発明の一実施形態に係る継合部材４について説明する。図示のように、本発明の一実施形態に係る継合部材４は、釣竿１の前側の竿体（図示しない）と後側の竿体（図示しない）とが着脱可能にされる継合部材４であって、筒状に形成され、該前側の竿体１１が取付け可能な第１の継合部１３と、筒状に形成され、該後側の竿体１２が取付け可能な第２の継合部１４と、これらを接続する中央部１５と、を備える。また、該前側の竿体１１は、該第１の継合部１３の内面に取付け可能にされ、該後側の竿体１２は、該第２の継合部１４の外面に取付け可能にされる。また、中央部１５は、中空部１６を備え、図７の場合とは逆に、第１の継合部１３から第２の継合部１４へ向けて、内径及び外径ともに小さくなるように形成されている。本態様では、継合部材が竿先から竿元にかけて剛性が低くなるように形成されることで、剛性を確保した先節と操作性がよくしっかりした元節との間を、継ぎ目はるもののより重い錘にも耐え得る継合部として形成することが可能となる。 Next, referring to FIG. 8, the joint member 4 according to one embodiment of the present invention will be described. As shown in the figure, the joint member 4 according to one embodiment of the present invention is a joint member 4 that allows the front rod body (not shown) and the rear rod body (not shown) of the fishing rod 1 to be detachably attached, and includes a first joint portion 13 formed in a cylindrical shape to which the front rod body 11 can be attached, a second joint portion 14 formed in a cylindrical shape to which the rear rod body 12 can be attached, and a central portion 15 that connects them. The front rod body 11 can be attached to the inner surface of the first joint portion 13, and the rear rod body 12 can be attached to the outer surface of the second joint portion 14. The central portion 15 includes a hollow portion 16, and is formed so that both the inner diameter and the outer diameter become smaller from the first joint portion 13 to the second joint portion 14, in contrast to the case of FIG. 7. In this embodiment, the joint member is formed so that its rigidity decreases from the tip to the base of the rod, making it possible to form a joint between the tip section, which has sufficient rigidity, and the base section, which is easy to operate and sturdy, that can withstand heavier weights even though there is a seam.

本発明の一実施形態に係る継合部材４において、第１の継合部１３の内径は、第２の継合部１４の内径よりも小さく形成される。このようにして、異なる外径の竿体の継合が可能となる。 In the joint member 4 according to one embodiment of the present invention, the inner diameter of the first joint portion 13 is formed to be smaller than the inner diameter of the second joint portion 14. In this way, it is possible to join rod bodies with different outer diameters.

本発明の一実施形態に係る継合部材４において、第１の継合部１３の外径は、第２の継合部１４の外径よりも小さく形成される。このようにして、異なる外径の竿体の継合が可能となる。 In the joint member 4 according to one embodiment of the present invention, the outer diameter of the first joint portion 13 is formed to be smaller than the outer diameter of the second joint portion 14. In this way, it is possible to join rod bodies with different outer diameters.

本発明の一実施形態に係る継合部材４において、第１の継合部１３の内面は、中央部１５とは反対側の方向に向かうにつれ内径が大きくなるように構成される。このようにして、前側の竿体１１の継合部外径並びに形状を継合部１３に近い外径とし、継合することで前側の竿体１１と係合部１３の剛性が近くなる事で、繋がりをよくする（竿体２の曲がりがスムーズとなる）ことができる。 In the joint member 4 according to one embodiment of the present invention, the inner surface of the first joint portion 13 is configured so that the inner diameter increases in the direction opposite to the center portion 15. In this way, the outer diameter and shape of the joint portion of the front rod body 11 are made close to the outer diameter of the joint portion 13, and by joining them, the rigidity of the front rod body 11 and the engagement portion 13 becomes close, improving the connection (making the rod body 2 bend more smoothly).

本発明の一実施形態に係る継合部材４において、中央部１５は、中空部１６を有し、該中央部１５は、第１の継合部１３側の第１の端部１７から、前記第２の継合１４部側の第２の端部１８に向かうにつれその内径が大きくなるように構成される。このようにして、継合部材４の剛性の調整、継合が想定される竿体との径調整、異なる外径の竿体との継合が可能となる。 In the joint member 4 according to one embodiment of the present invention, the central portion 15 has a hollow portion 16, and the central portion 15 is configured so that its inner diameter increases from the first end portion 17 on the side of the first joint portion 13 to the second end portion 18 on the side of the second joint portion 14. In this way, it is possible to adjust the rigidity of the joint member 4, adjust the diameter with the rod body to which it is intended to be joined, and join to rod bodies with different outer diameters.

本発明の一実施形態に係る継合部材４において、中央部１５は、中空部１６を有し、該中空部１６は、第１の継合部１３側の第１の端部１７から第２の継合部１４側の第２の端部１８までその内径が同じであるように構成される。このようにして、同一の外径の竿体との継合、同一の竿体との継合を継合部材４を前後反転しての使用が可能となる。 In the joint member 4 according to one embodiment of the present invention, the central portion 15 has a hollow portion 16, and the hollow portion 16 is configured so that its inner diameter is the same from the first end portion 17 on the first joint portion 13 side to the second end portion 18 on the second joint portion 14 side. In this way, it is possible to use the joint member 4 by flipping it back and forth to join to a rod body of the same outer diameter, or to join to the same rod body.

本発明の一実施形態に係る継合部材４において、中央部１５は、その外径が、第１の継合部１３の外径よりも大きく、かつ第２の継合部１４の外径と同じ若しくは小さく形成される。このようにして、先から元にかけて順々に拡径しており、違和感のない外観の形成が可能となる。 In the joint member 4 according to one embodiment of the present invention, the central portion 15 is formed with an outer diameter larger than the outer diameter of the first joint portion 13 and equal to or smaller than the outer diameter of the second joint portion 14. In this way, the diameter gradually increases from the tip to the base, making it possible to create a natural appearance.

本発明の一実施形態に係る継合部材４は、繊維強化樹脂材料により形成され、その径方向でみて、繊維方向の異なる複数の繊維強化樹脂層により形成される。このようにして、強度を維持しながら軽量化する事が可能となる。ここで、繊維強化樹脂材料の繊維として、カーボン繊維、ガラス繊維又はボロン繊維が考えられるが、これらに限られない。また、繊維強化樹脂材料の樹脂として、エポキシ樹脂、ビニルエステル樹脂が考えられるがこれらに限られない。 The joint member 4 according to one embodiment of the present invention is made of a fiber-reinforced resin material, and is formed of multiple fiber-reinforced resin layers with different fiber directions in the radial direction. In this way, it is possible to reduce weight while maintaining strength. Here, the fibers of the fiber-reinforced resin material may be, but are not limited to, carbon fiber, glass fiber, or boron fiber. Also, the resin of the fiber-reinforced resin material may be, but is not limited to, epoxy resin or vinyl ester resin.

本発明の一実施形態に係る釣竿１は、上記いずれかに記載の継合部材４と、前側の竿体１１と、後側の竿体１２と、を備えるように構成される。このようにして、本発明の一実施形態に係る継合部材を備えた釣竿によれば、元節と先節のいずれも着脱可能としながら、様々な寸法及び形状の元節と先節を継合可能とすることで、元節と先節を柔軟に選択可能とし、釣竿の使用者の種々異なる様々な要求に応えることを可能とする継合部材を備えた釣竿を提供することが可能となる。 The fishing rod 1 according to one embodiment of the present invention is configured to include any of the joint members 4 described above, a front rod body 11, and a rear rod body 12. In this way, with a fishing rod equipped with a joint member according to one embodiment of the present invention, it is possible to provide a fishing rod equipped with a joint member that allows the base section and tip section to be flexibly selected by making both the base section and tip section detachable and allowing the base section and tip section to be joined to each other in various sizes and shapes, thereby meeting the various and varied needs of fishing rod users.

次に、図９－１２を参照して、本発明の一実施形態に係る継合部材４の繊維方向の異なる複数の繊維強化樹脂層についてより詳細に説明する。まず、図９に示すように、本発明の一実施形態に係る継合部材４における複数の繊維強化樹脂層は、内側層２１と、外側層２２とで構成されている（内側層と外側層が逆になっていてもよい）。内側層２１は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに垂直な方向（９０°）に指向するように引き揃えられており、外側層２２も、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに平行な方向（０°）に指向するように引き揃えられている。これらの層構造により、曲げ強度と潰れ強度を両立させることが可能となる。なお、層の数や弾性率を調整することで、弾性の程度を調整することができる。また、図示の例では、継合部材４の中央領域は、継合部材４の軸方向（釣竿１の軸方向）に垂直な方向に膨出するように形成されている。これは、継合部１３、１４との剛性差を小さく、又は調整するためである。 Next, referring to Figures 9-12, the multiple fiber-reinforced resin layers with different fiber directions of the joint member 4 according to one embodiment of the present invention will be described in more detail. First, as shown in Figure 9, the multiple fiber-reinforced resin layers in the joint member 4 according to one embodiment of the present invention are composed of an inner layer 21 and an outer layer 22 (the inner layer and the outer layer may be reversed). The inner layer 21 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction perpendicular to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (90°), and the outer layer 22 is also a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction parallel to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (0°). These layer structures make it possible to achieve both bending strength and crushing strength. The degree of elasticity can be adjusted by adjusting the number of layers and the elastic modulus. In the illustrated example, the central region of the joint member 4 is formed to bulge in a direction perpendicular to the axial direction of the joint member 4 (the axial direction of the fishing rod 1). This is to reduce or adjust the difference in rigidity between the joints 13 and 14.

次に、図１０に示すように、本発明の一実施形態に係る継合部材４における複数の繊維強化樹脂層は、内側層２３と、外側層２４とで構成されている（内側層と外側層が逆になっていてもよい）。内側層２３は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに平行な方向（０°）に指向するように引き揃えられており、外側層２４も、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに対してバイアスする方向（すなわち、±４５°）に指向するように引き揃えられている。これらの層構造により、曲げ強度と捻じれ捻れ強度を両立させることが可能となる。また、継合部材４の軸方向の端部領域において、バイアスの割合を多くすることで、継合部材４のせん断歪を抑制することができるため、良好な繋がりを形成することができる。なお、層の数や弾性率を調整することで、弾性の程度を調整することができる。また、図示の例では、継合部材４の中央領域は、継合部材４の軸方向（釣竿１の軸方向）に垂直な方向に膨出するように形成されている。これは、継合部１３、１４との剛性差を小さく、又は調整するためである。 Next, as shown in FIG. 10, the multiple fiber-reinforced resin layers in the joint member 4 according to one embodiment of the present invention are composed of an inner layer 23 and an outer layer 24 (the inner layer and the outer layer may be reversed). The inner layer 23 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction parallel to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (0°), and the outer layer 24 is also a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a bias direction (i.e., ±45°) relative to the axial direction of the joint member 4 (axial direction of the fishing rod 1). These layer structures make it possible to achieve both bending strength and torsional strength. In addition, by increasing the proportion of bias in the end region in the axial direction of the joint member 4, the shear strain of the joint member 4 can be suppressed, and a good connection can be formed. The degree of elasticity can be adjusted by adjusting the number of layers and the elastic modulus. In the illustrated example, the central region of the joint member 4 is formed to bulge in a direction perpendicular to the axial direction of the joint member 4 (the axial direction of the fishing rod 1). This is to reduce or adjust the difference in rigidity between the joints 13 and 14.

次に、図１１に示すように、本発明の一実施形態に係る継合部材４における複数の繊維強化樹脂層は、内側層２５と、外側層２６とで構成されている（内側層と外側層が逆になっていてもよい）。内側層２５は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに垂直な方向（９０°）に指向するように引き揃えられており、外側層２６も、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに対してバイアスする方向（すなわち、±４５°）に指向するように引き揃えられている。これらの層構造により、潰れ強度と捻じれ捻れ強度を両立させることが可能となる。また、継合部材４の軸方向の端部領域において、バイアスの割合を多くすることで、継合部材４のせん断歪を抑制することができるため、良好な繋がりを形成することができる。なお、層の数や弾性率を調整することで、弾性の程度を調整することができる。また、図示の例では、継合部材４の中央領域は、継合部材４の軸方向（釣竿１の軸方向）に垂直な方向に膨出するように形成されている。これは、継合部１３、１４との剛性差を小さく、又は調整するためである。 Next, as shown in FIG. 11, the multiple fiber-reinforced resin layers in the joint member 4 according to one embodiment of the present invention are composed of an inner layer 25 and an outer layer 26 (the inner layer and the outer layer may be reversed). The inner layer 25 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction perpendicular to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (90°), and the outer layer 26 is also a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a bias direction (i.e., ±45°) relative to the axial direction of the joint member 4 (axial direction of the fishing rod 1). These layer structures make it possible to achieve both crush strength and torsional strength. In addition, by increasing the proportion of bias in the end region in the axial direction of the joint member 4, the shear strain of the joint member 4 can be suppressed, and a good connection can be formed. The degree of elasticity can be adjusted by adjusting the number of layers and the elastic modulus. In the illustrated example, the central region of the joint member 4 is formed to bulge in a direction perpendicular to the axial direction of the joint member 4 (the axial direction of the fishing rod 1). This is to reduce or adjust the difference in rigidity between the joints 13 and 14.

次に、図１２に示すように、本発明の一実施形態に係る継合部材４における複数の繊維強化樹脂層は、内側層２７と、中間層２８と、外側層２９とで構成されている（内側層と外側層が逆になっていてもよい）。内側層２７は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに垂直な方向（９０°）に指向するように引き揃えられており、中間層２８は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに平行な方向（０°）に指向するように引き揃えられており、外側層２９は、長繊維強化樹脂層であり、その長繊維は、継合部材４の軸方向（釣竿１の軸方向）でみて、これに対してバイアスする方向（すなわち、±４５°）に指向するように引き揃えられている。これらの層構造により、曲げ強度と潰れ強度と捻じれ捻れ強度とを両立させることが可能となる。また、継合部材４の軸方向の端部領域において、バイアスの割合を多くすることで、継合部材４のせん断歪を抑制することができるため、良好な繋がりを形成することができる。なお、層の数や弾性率を調整することで、弾性の程度を調整することができる。また、図示の例では、継合部材４の中央領域は、継合部材４の軸方向（釣竿１の軸方向）に垂直な方向に膨出するように形成されている。これは、継合部１３、１４との剛性差を小さく、又は調整するためである。 Next, as shown in FIG. 12, the multiple fiber-reinforced resin layers in the joint member 4 according to one embodiment of the present invention are composed of an inner layer 27, an intermediate layer 28, and an outer layer 29 (the inner layer and the outer layer may be reversed). The inner layer 27 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction perpendicular to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (90°), the intermediate layer 28 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a direction parallel to the axial direction of the joint member 4 (axial direction of the fishing rod 1) (0°), and the outer layer 29 is a long fiber-reinforced resin layer, and its long fibers are aligned so as to be oriented in a bias direction (i.e., ±45°) relative to the axial direction of the joint member 4 (axial direction of the fishing rod 1).
