Description

本発明は釣竿のジョイント部製造方法、釣竿ジョイント部品の製造方法及び釣竿に係わり、特に釣の最中にロッドが釣竿の周方向にずれたり、がたつくことが無く釣り針を遠くに飛ばすことの可能な釣竿のジョイント部製造方法、釣竿ジョイント部品の製造方法及び釣竿に関する。   The present invention relates to a method for manufacturing a joint for a fishing rod, a method for manufacturing a fishing rod joint part, and a fishing rod, and in particular, the rod can be distant in the circumferential direction of the fishing rod during fishing and the fishing hook can be moved far away. The present invention relates to a method for manufacturing a joint for a fishing rod, a method for manufacturing a fishing rod joint part, and a fishing rod.

釣竿が手元側から見て例えば手元セクション、中間セクション、先端セクションの３本で構成されている場合、互いの間はジョイント部にて接続される（特許文献１を参照）。この手元セクションのロッドの先端には従来円形の穴が開けられ、この円形穴に対して接続先である中間セクションのロッドの根元部分が、また、中間セクションのロッドの先端にも同様に中空の円形穴が開けられ、この円形穴に対して接続先である先端セクションのロッドの根元部分が継ぎ足されるようになっている。   When the fishing rod is composed of, for example, a hand section, an intermediate section, and a tip section as viewed from the hand side, they are connected to each other by a joint portion (see Patent Document 1). The tip of the rod of this proximal section has been conventionally drilled with a circular hole, and the root of the rod of the intermediate section connected to this circular hole is also hollow at the tip of the rod of the intermediate section. A circular hole is formed, and the root portion of the rod of the tip section to which the circular hole is connected is added to the circular hole.

そして、このような円形穴とこの円形穴に対する接続先である中間セクションや先端セクションのロッドの根元部分はそれぞれ別体の状態で作られていた。また、手元セクション、中間セクション、先端セクションのそれぞれの外周にはガイドが取り付けられ、このガイドに対して糸が通されるようになっている。釣竿を組み合わせる際には、このガイドの向きが最終的に合うようにねじりながら先端側のロッドを調整しつつ挿入する。   And such a circular hole and the base part of the rod of the intermediate section and the tip section which are the connection destinations to this circular hole were made in a separate state. A guide is attached to the outer periphery of each of the hand section, the intermediate section, and the tip section, and a thread is passed through the guide. When assembling the fishing rod, the rod on the tip side is adjusted and inserted while twisting so that the direction of the guide finally matches.

特開２０００−０３２８８１号公報JP 2000-032881 A

しかしながら、従来の釣竿ではこの釣竿を組み合わせる際に、ロッドをねじりながら挿入したり外したりする必要があるためジョイント部の円形穴部分で磨耗し遊びを生じ易い。従って、このような場合に釣竿を振り子運動等させると、ジョイント部において先端側のロッドが周方向に回転しずれの生じることがある。   However, in the conventional fishing rod, when this fishing rod is combined, it is necessary to insert or remove the rod while twisting it, so that the circular hole portion of the joint portion is worn and play tends to occur. Accordingly, if the fishing rod is moved in a pendulum motion in such a case, the rod on the distal end side may rotate in the circumferential direction at the joint portion and cause a shift.

この場合には、ガイドの位置も回転して最初の調整位置よりも次第にずれるため糸がまっすぐには延びず、抵抗となり釣り針を遠くに飛ばせなくなるおそれがあった。
また、このような現象が起こる都度釣竿の周方向の位置を調整する必要があった。
更に、この遊びにより釣竿にガタツキを生ずるおそれがあった。 In this case, since the position of the guide also rotates and gradually shifts from the initial adjustment position, the thread does not extend straight, and there is a possibility that it becomes a resistance and the fishing hook cannot be moved far away.
Moreover, it is necessary to adjust the circumferential position of the fishing rod every time such a phenomenon occurs.
Further, this play may cause rattling in the fishing rod.

本発明はこのような従来の課題に鑑みてなされたもので、釣の最中にロッドが釣竿の周方向にずれたり、がたつくことが無く釣り針を遠くに飛ばすことの可能な釣竿のジョイント部製造方法、釣竿ジョイント部品の製造方法及び釣竿を提供することを目的とする。   The present invention has been made in view of the above-described conventional problems, and can produce a joint portion of a fishing rod that can fly a fishhook far away without causing the rod to shift or rattle in the circumferential direction of the fishing rod during fishing. It is an object to provide a method, a method for manufacturing a fishing rod joint component, and a fishing rod.

このため本発明（請求項１）は、第１のロッドの手元側端に突設された外周に真円ではない凹部若しくは凸部が形成された嵌合用突設部を第２のロッドの先端部の嵌合用開口内に埋め込まれた樹脂の内側に形成された嵌合用凹部に対し挿入接続自在とする釣竿のジョイント部製造方法であって、前記嵌合用突設部の外周に離型剤を塗布した後、該嵌合用突設部の周囲に繊維を巻き、該繊維を樹脂で固化し、該樹脂を前記嵌合用開口の形状に合わせて切削した後、前記嵌合用突設部を該嵌合用開口内に挿入した状態で前記樹脂を再び固化した後、前記嵌合用突設部を引き抜くことで、前記嵌合用突設部の外周の形状に一致した形状の嵌合用凹部を有する樹脂部分を前記嵌合用開口内に残すことを特徴とする。   For this reason, the present invention (Claim 1) provides a fitting projecting portion in which a non-circular recess or projection is formed on the outer periphery projecting from the proximal end of the first rod. A method of manufacturing a joint part for a fishing rod that can be inserted and connected to a fitting recess formed inside a resin embedded in a fitting opening of the fitting part, wherein a release agent is provided on the outer periphery of the fitting projecting part. After coating, a fiber is wound around the fitting protrusion, the fiber is solidified with resin, and the resin is cut in accordance with the shape of the fitting opening, and then the fitting protrusion is fitted. After the resin is solidified again in a state of being inserted into the joint opening, the resin projecting portion having a fitting concave portion having a shape matching the shape of the outer periphery of the fitting projecting portion is pulled out by pulling out the fitting projecting portion. It remains in the opening for fitting.

嵌合用突設部の周囲に繊維を巻き、この繊維を樹脂で固化する。嵌合用突設部を嵌合用開口内に挿入した状態で樹脂を固化した後、嵌合用突設部を引き抜くと離型剤の作用により嵌合用突設部のみが引き抜かれる。このとき、嵌合用突設部の外周の形状に一致した形状の嵌合用凹部を有する樹脂部分が嵌合用開口内に残される。   A fiber is wound around the protruding portion for fitting, and the fiber is solidified with a resin. After the resin is solidified in a state where the fitting projecting portion is inserted into the fitting opening, when the fitting projecting portion is pulled out, only the fitting projecting portion is pulled out by the action of the release agent. At this time, a resin portion having a fitting recess having a shape that matches the shape of the outer periphery of the fitting protrusion is left in the fitting opening.

このため、釣竿を組み合わせた場合に遊びが無くガタツキを全く無くすことができる。ガイドの位置も一定であり、糸が常にまっすぐ延びているため、糸がガイドに接触することに伴う抵抗も無く釣り針を遠くに飛ばせる。また、釣の間に釣竿の周方向の位置を調整する必要も無い。   For this reason, when a fishing rod is combined, there is no play and rattling can be completely eliminated. Since the position of the guide is constant and the thread always extends straight, there is no resistance associated with the thread coming into contact with the guide, and the fishing hook can be moved away. Further, there is no need to adjust the circumferential position of the fishing rod during fishing.

また、本発明（請求項２）は、釣竿のロッド同士を接続するジョイント部品の製造方法であって、該ジョイント部品が第１のロッドに対し装着される装着用部材と、該装着用部材の手元側端に突設された外周に真円ではない凹部若しくは凸部が形成された嵌合用突設部とを有し、該嵌合用突設部を第２のロッドの先端部の嵌合用開口内に埋め込まれた樹脂の内側に形成された嵌合用凹部に対し挿入接続自在であり、前記嵌合用突設部の外周に離型剤を塗布した後、該嵌合用突設部の周囲に繊維を巻き、該繊維を樹脂で固化し、該樹脂を前記嵌合用開口の形状に合わせて切削した後、前記嵌合用突設部を該嵌合用開口内に挿入した状態で前記樹脂を再び固化した後、前記嵌合用突設部を引き抜くことで、前記嵌合用突設部の外周の形状に一致した形状の嵌合用凹部を有する樹脂部分を前記嵌合用開口内に残すことを特徴とする。   Further, the present invention (Claim 2) is a method of manufacturing a joint part for connecting rods of a fishing rod, wherein the joint part is attached to the first rod, and the mounting member And a fitting projecting portion formed with a concave or convex portion that is not a perfect circle on the outer periphery projecting from the proximal side end, and the fitting projecting portion is used as a fitting opening at the tip of the second rod. It can be freely inserted into and connected to the fitting recess formed inside the resin embedded in the resin, and after a release agent is applied to the outer periphery of the fitting projection, a fiber is formed around the fitting projection. The fiber was solidified with resin, and the resin was cut in accordance with the shape of the fitting opening, and then the resin was solidified again with the fitting protrusions inserted into the fitting opening. After that, by pulling out the protrusion for fitting, it matches the shape of the outer periphery of the protrusion for fitting. The resin portion having a fitting concave portion of the shape, characterized in that to leave the fitting in the opening.

以上により、ジョイント部品のみを一様な仕様で量産することができる。ジョイント部品は、各種のロッドに対し簡単に固着できるので釣竿の製造が楽にできる。   As described above, only joint parts can be mass-produced with uniform specifications. Since the joint parts can be easily fixed to various rods, the fishing rod can be easily manufactured.

更に、本発明（請求項３）は釣竿の発明であって、断面形状が真円ではない凹部が内側に形成された第１のロッド又は第１のジョイント部品と、該第１のロッド又は第１のジョイント部品の凹部に対し挿入接続自在とする前記凹部の形状に合わせて形成された嵌合用突設部を端部に有する第２のロッドとを備えて構成した。   Further, the present invention (Claim 3) is an invention of a fishing rod, wherein the first rod or the first joint part having a recess whose cross-sectional shape is not a perfect circle is formed on the inside, and the first rod or the first And a second rod having a fitting projecting portion formed at the end portion so as to conform to the shape of the concave portion that can be inserted and connected to the concave portion of one joint component.

第１のロッド又は第１のジョイント部品の端部には凹部が形成されている。この凹部は断面形状が真円ではない。
従って、第１のロッド又は第１のジョイント部品の凹部に対し嵌合用突設部が挿入されたときに釣竿が周方向にずれることは無くなる。 A recess is formed at the end of the first rod or the first joint part. This recess has a non-circular cross-sectional shape.
Therefore, the fishing rod does not shift in the circumferential direction when the fitting protrusion is inserted into the concave portion of the first rod or the first joint part.

以上説明したように本発明（請求項１）によれば、嵌合用突設部の外周の形状に一致した形状の嵌合用凹部を有する樹脂部分が嵌合用開口内に残されるため、釣竿を組み合わせた場合に遊びが無くガタツキを全く無くすことができる。また、釣の間に釣竿の周方向の位置を調整する必要も無い。   As described above, according to the present invention (Claim 1), since the resin portion having the concave portion for fitting that matches the shape of the outer periphery of the protruding portion for fitting is left in the fitting opening, the fishing rod is combined. If there is no play, there is no play at all. Further, there is no need to adjust the circumferential position of the fishing rod during fishing.

また、本発明（請求項２）によれば、ジョイント部品が第１のロッドに対し装着されるように構成したので、ジョイント部品のみを一様な仕様で量産することができる。ジョイント部品は、各種のロッドに対し簡単に固着できるので釣竿の製造が楽にできる。   Further, according to the present invention (Claim 2), since the joint part is configured to be attached to the first rod, only the joint part can be mass-produced with uniform specifications. Since the joint parts can be easily fixed to various rods, the fishing rod can be easily manufactured.

以下、本発明の第１実施形態について説明する。本発明の第１実施形態である釣竿のジョイント部の構造を図２及び図７を基に説明する。図２には、釣竿の中間セクション回りのジョイント部分の構成図を示し、図７には手元セクション回りのジョイント部分の構成図を示す。   The first embodiment of the present invention will be described below. The structure of the joint part of the fishing rod which is 1st Embodiment of this invention is demonstrated based on FIG.2 and FIG.7. FIG. 2 shows a configuration diagram of the joint portion around the middle section of the fishing rod, and FIG. 7 shows a configuration diagram of the joint portion around the hand section.

図２において、中間セクション１０のロッド１の外形は８角形状に形成されており、そのロッド１の根元部分にはロッド１の外径よりも小さい外径を有する嵌合用突設部３が突出されている。但し、これとは逆に嵌合用突設部３の外径がロッド１の外径よりも大きくなるように形成されてもよい。   In FIG. 2, the outer shape of the rod 1 of the intermediate section 10 is formed in an octagonal shape, and a fitting projecting portion 3 having an outer diameter smaller than the outer diameter of the rod 1 protrudes at the root portion of the rod 1. Has been. However, on the contrary, it may be formed such that the outer diameter of the fitting protrusion 3 is larger than the outer diameter of the rod 1.

一方、図７において、手元セクション２０のジョイント部２３の嵌合用開口２５内に固着されたエポキシ樹脂９にはロッド１の８角形状に等しい大きさの嵌合用凹部２７が形成されている。そして、この手元セクション２０の嵌合用凹部２７内に中間セクション１０の嵌合用突設部３が接続自在になっている。   On the other hand, in FIG. 7, a fitting concave portion 27 having a size equal to the octagonal shape of the rod 1 is formed in the epoxy resin 9 fixed in the fitting opening 25 of the joint portion 23 of the hand section 20. The fitting projection 3 of the intermediate section 10 can be freely connected to the fitting recess 27 of the hand section 20.

次に、本発明の第１実施形態である釣竿のジョイント部を製造する方法について図１〜図７を基に説明する。
図１には、本実施形態の製造工程の全体フローを示す。図１のステップ１においては、釣竿の中間セクション１０のロッド１に切削を施しジョイント部分を形成する。 Next, a method for manufacturing the joint portion of the fishing rod according to the first embodiment of the present invention will be described with reference to FIGS.
In FIG. 1, the whole flow of the manufacturing process of this embodiment is shown. In step 1 of FIG. 1, the rod 1 of the intermediate section 10 of the fishing rod is cut to form a joint portion.

手元セクション２０、中間セクション１０、図示しない先端セクションの３本のロッドは共に材質が例えばカーボンで形成されている。但し、ロッドは複数本であればよく、３本に限定するものではない。ロッド１の外形及び嵌合用突設部３の外形は共にＮＣフライス盤等により切削され、例えば図２に示すように８角形状に形成する。   The three rods of the hand section 20, the intermediate section 10, and the tip section (not shown) are all formed of carbon, for example. However, the number of rods is not limited to three as long as it is plural. Both the outer shape of the rod 1 and the outer shape of the fitting projecting portion 3 are cut by an NC milling machine or the like, and formed in an octagonal shape as shown in FIG. 2, for example.

次に、ステップ２において、この嵌合用突設部３の周囲に離型剤５を塗布する。離型剤５は例えばフッ素樹脂（テフロン（登録商標））であるがシリコン樹脂等でも可能である。次に、ステップ３においては、図３に示すようにこの嵌合用突設部３の周囲に炭素繊維７を巻く。その後、ステップ４において、図４に示すようにこの巻かれた炭素繊維７をエポキシ樹脂９で固め、ステップ５において、図示しない加熱炉で１００℃程度で約１時間加熱する。この加熱が完了した後、ステップ６で自然冷却させる。   Next, in step 2, a release agent 5 is applied around the fitting projecting portion 3. The release agent 5 is, for example, a fluororesin (Teflon (registered trademark)), but may be a silicon resin or the like. Next, in step 3, as shown in FIG. 3, the carbon fiber 7 is wound around the protrusion 3 for fitting. Thereafter, in step 4, the wound carbon fiber 7 is hardened with an epoxy resin 9 as shown in FIG. After this heating is completed, it is naturally cooled in step 6.

ステップ７において、このエポキシ樹脂９の樹脂部分を図５に示すように円断面に加工する。加工後のエポキシ樹脂９の円断面の直径は図６（Ａ）に示すように釣竿の手元セクション２０のロッド２１の先端部分に形成されたジョイント部２３に設けられた円形の嵌合用開口２５の直径に等しい。   In step 7, the resin portion of the epoxy resin 9 is processed into a circular cross section as shown in FIG. The diameter of the circular cross section of the epoxy resin 9 after processing is such that the circular fitting opening 25 provided in the joint portion 23 formed at the tip portion of the rod 21 of the hand section 20 of the fishing rod as shown in FIG. Equal to diameter.

なお、この嵌合用開口２５は予めドリルで丸穴に削られている。但し、丸穴に限定するものではない。また、手元セクション２０のロッド２１及びジョイント部２３の外形も中間セクション１０側と同様に８角形状に形成されている。   The fitting opening 25 is previously cut into a round hole with a drill. However, it is not limited to a round hole. Further, the outer shapes of the rod 21 and the joint portion 23 of the hand section 20 are formed in an octagonal shape as in the intermediate section 10 side.

ステップ８では、図６（Ｂ）に示すようにこの円断面に加工された中間セクション１０の嵌合用突設部を手元セクション２０の嵌合用開口２５に挿入する。その後、ステップ９ではこの状態で再び加熱路に入れ１００℃程度で約１時間加熱する。このとき、エポキシ樹脂９の樹脂部分は嵌合用開口２５内で手元セクション２０のロッド２１のジョイント部２３の内面と固着する。   In step 8, as shown in FIG. 6B, the fitting projecting portion of the intermediate section 10 processed into this circular cross section is inserted into the fitting opening 25 of the proximal section 20. Then, in step 9, it puts in a heating path again in this state, and heats at about 100 degreeC for about 1 hour. At this time, the resin portion of the epoxy resin 9 is fixed to the inner surface of the joint portion 23 of the rod 21 of the proximal section 20 in the fitting opening 25.

この加熱が完了した後、ステップ１０で中間セクション１０を引き抜く。中間セクション１０の嵌合用突設部３の周囲には離型剤５が塗布されているので、図６（Ｃ）に示すようにこの際にはエポキシ樹脂９の部分は嵌合用開口２５内に固着され残った形で嵌合用突設部３のみが引き抜かれる。   After this heating is complete, in step 10 the intermediate section 10 is withdrawn. Since the release agent 5 is applied to the periphery of the fitting projecting portion 3 of the intermediate section 10, the portion of the epoxy resin 9 is placed in the fitting opening 25 at this time as shown in FIG. Only the projecting portion 3 for fitting is pulled out in a form that remains fixed.

その結果、図７に示すように手元セクション２０のロッド２３の嵌合用開口２５内に残された樹脂部分９の内側には嵌合用突設部３の８角形の外形と同一の形状を持った嵌合用凹部２７が形成される。この嵌合用凹部２７の周囲には炭素繊維７が巻かれているので樹脂部分は十分な強度を有している。以上の工程は、中間セクション１０と図示しない先端セクション間でも同様に適用される。   As a result, as shown in FIG. 7, the resin portion 9 left in the fitting opening 25 of the rod 23 of the hand section 20 has the same shape as the octagonal outer shape of the fitting projection 3. A fitting recess 27 is formed. Since the carbon fiber 7 is wound around the fitting recess 27, the resin portion has sufficient strength. The above process is similarly applied between the intermediate section 10 and a tip section (not shown).

このことにより、嵌合用突設部３の外形と完全一致した嵌合用凹部２７が手元セクション２０側に形成されるため、釣竿を組み合わせた場合に遊びが無くガタツキが全く無い。   As a result, a fitting recess 27 that is completely coincident with the outer shape of the fitting projection 3 is formed on the hand section 20 side, so there is no play and no rattling when a fishing rod is combined.

ガイドの位置も一定であり、糸が常にまっすぐ延びているため、糸がガイドに接触することに伴う抵抗も無く釣り針を遠くに飛ばせる。また、釣の間に釣竿の周方向の位置を調整する必要も無い。   Since the position of the guide is constant and the thread always extends straight, there is no resistance associated with the thread coming into contact with the guide, and the fishing hook can be moved away. Further, there is no need to adjust the circumferential position of the fishing rod during fishing.

次に、本発明の第２実施形態について説明する。第１実施形態ではジョイント部をロッドと一体加工した釣竿について説明したが、本発明の第２実施形態では、ジョイント部分のみを部品としてロッドとは別に製造し、製造したジョイント部品の一端をロッドに対して固着させるものである。なお、釣竿のジョイント部を製造する方法については第１実施形態と同様であるので説明を省略する。   Next, a second embodiment of the present invention will be described. In the first embodiment, the fishing rod in which the joint portion is integrally processed with the rod has been described. However, in the second embodiment of the present invention, only the joint portion is manufactured separately from the rod, and one end of the manufactured joint component is used as the rod. It is made to adhere to. In addition, about the method to manufacture the joint part of a fishing rod, since it is the same as that of 1st Embodiment, description is abbreviate | omitted.

図８に示すように、ジョイント部品３０の断面円形の装着用円柱部材３１の一端にはこの装着用円柱部材３１の外径よりも小さい外径を有する嵌合用突設部３３が突出されている。但し、これとは逆に嵌合用突設部３３の外径が装着用円柱部材３１の外径よりも大きくなるように形成されてもよい。嵌合用突設部３３の外形はＮＣフライス盤等により切削され、例えば８角形状に形成されている。   As shown in FIG. 8, a fitting projection 33 having an outer diameter smaller than the outer diameter of the mounting column member 31 protrudes from one end of the mounting column member 31 having a circular cross section of the joint component 30. . However, conversely, the fitting protruding portion 33 may be formed so that the outer diameter thereof is larger than the outer diameter of the mounting column member 31. The outer shape of the fitting projecting portion 33 is cut by an NC milling machine or the like, and is formed in, for example, an octagonal shape.

その後、図１のステップ２〜ステップ７と同様に嵌合用突設部３３の周囲には、離型剤５を塗布し、その後、嵌合用突設部３３の周囲に炭素繊維７を巻き、この巻かれた炭素繊維７をエポキシ樹脂９で固めた後、このエポキシ樹脂９の樹脂部分を円断面に加工する。   Thereafter, as in Steps 2 to 7 of FIG. 1, the release agent 5 is applied to the periphery of the fitting projection 33, and then the carbon fiber 7 is wound around the fitting projection 33. After the wound carbon fiber 7 is hardened with an epoxy resin 9, the resin portion of the epoxy resin 9 is processed into a circular cross section.

このように完成したジョイント部品３０は全体の長さが例えば２０ｍｍ〜５０ｍｍ程度であり、このジョイント部品３０の装着用円柱部材３１は中間セクション４０におけるロッド４１の手元側端部に形成された円形の開口４３内に挿入され、接着剤等により固着される。なお、手元セクション２０のロッド２１の嵌合用開口２５内に残された樹脂部分９の内側には嵌合用突設部３３の８角形の外形と同一の形状を持った嵌合用凹部２７が形成される点は第１実施形態と同様である。   The total length of the joint component 30 thus completed is about 20 mm to 50 mm, for example, and the mounting column member 31 of the joint component 30 is a circular shape formed at the proximal end of the rod 41 in the intermediate section 40. It is inserted into the opening 43 and fixed with an adhesive or the like. A fitting recess 27 having the same shape as the octagonal outer shape of the fitting projection 33 is formed inside the resin portion 9 left in the fitting opening 25 of the rod 21 of the hand section 20. This is the same as in the first embodiment.

以上により、ジョイント部品３０のみを一様な仕様で量産することができる。ジョイント部品３０は、各種のロッドに対し簡単に固着できるので釣竿の製造が楽にできる。   As described above, only the joint component 30 can be mass-produced with uniform specifications. Since the joint part 30 can be easily fixed to various rods, the fishing rod can be easily manufactured.
