Description

【０００１】
【発明の属する技術分野】
本発明は、複数の竿体をいわゆる振出形式で連結した釣竿に関する。特に、特定の竿体同士を収納状態，延伸状態の何れにおいても相互に連結固定可能とし、竿全体の長さを変化させて釣りを行えるように工夫した釣竿に関する。
【０００２】
【従来の技術】
従来の振出形式の釣竿は、複数の筒状の竿体が穂先側の竿体から順次竿元側の竿体内に挿入可能になっている。釣りを行う際には各竿体を順次穂先側に引き出して嵌合固定して一本の竿体として用いる。一方、収納時には穂先側の竿体を順次竿元側の竿体内に収納してコンパクトな状態とする。
【０００３】
また、従来の振出形式の釣竿には竿全体の長さを変化させて釣りを行えるように工夫したものがある。このように工夫された釣竿は、例えば、穂先側端部内周面に嵌合雌部を有する元竿と、竿元側端部外周面に第１嵌合雄部を有しつつ長手方向中央付近の外周面に第２嵌合雄部を有する元上竿とを備える（例えば、特許文献１等参照）。
【０００４】
そして、この種の釣竿では、元竿の穂先側に連結される元上竿が穂先側に引き出された状態（以下「延伸状態」という）では、嵌合雌部を第１嵌合雄部と嵌着させ、元上竿が元竿内に挿入された状態（以下「収納状態」という）では、嵌合雌部を第２嵌合雄部と嵌着させることが可能となっている。
【０００５】
こうして、元竿と元上竿とは「延伸状態」，「収納状態」のいずれの状態においても互いに嵌合固定可能であり、状況に応じて釣竿全体の長さを変化させて釣りを行えるようになっている。
【０００６】
【特許文献１】
特開２０００−２６２１８９号公報（第１〜第２欄，図１，図２）
【０００７】
【発明が解決しようとする課題】
上述のような釣竿全体の長さを変化させることが可能な釣竿において「延伸状態」，「収納状態」の各状態に相互変換する際には、釣人は、一般に、一方の手で元竿の竿元側若しくはリールシート付近を把持しながら、他方の手で元上竿の第２嵌合雄部の穂先側付近を把持して、元上竿を元竿から引き出し若しくは収納する。このため、元上竿の引き出し長さには制約が発生する。
【０００８】
まず、第１の制約は釣人の手の長さによる制約である。
即ち、図１９に示すように、元上竿１０２を元竿１０１から引き出した際の「引き出し長さ」（リールシート付近から延伸状態における元上竿１０２の第２嵌合雄部１０２ｂの穂先側までの距離：図１９のＸ参照）を、釣人が手を広げた際の距離以上に長く設定し難い。
【０００９】
しかし、釣竿全体の長さを変化させ得るように工夫した釣竿は、収納状態と延伸状態との釣竿全体の長さの変化、即ち、元上竿を元竿から引き出した際の「引き出し長さ」を大きく設定し、状況に応じた釣りを容易に為し得ることを目的とするものである。そこで、より収納状態と延伸状態との釣竿全体の長さの変化を大きくし得るような工夫が求められる。
【００１０】
次に、第２の制約は構造上の制約である。
即ち、釣竿全体の長さを変化させ得るようにしたこの種の釣竿における「引き出し長さ」（図１９のＸ）は、一般に、元竿から引き出される元上竿の竿元側端部と、元上竿の穂先側の周面に太径化して形成される嵌合雄部との間の長さに一致する。何故なら、上述の図１９に示すように、元上竿の竿元側端部とこの嵌合雄部とが元竿の穂先側端部の嵌合雌部に嵌着するのが一般的だからである。このような構造上の制約は設計の自由度を大きく低下させる。
【００１１】
そこで、このような「引き出し長さ」の制限を回避して設計の自由度を高めるべく、延伸状態においても、元上竿の全てが元竿の穂先側に露出しないように、元上竿と元竿との嵌合部分を設定することが考えられる。
【００１２】
しかし、このような構造を元上竿に採用した場合、その元上竿の嵌合雄部より竿元側の領域は、元竿の外部に露出することなく常に元竿内に位置して、収納状態に於いて元竿の竿元側端部との嵌着のためのみに用いられることになる。このような元上竿の竿元側の領域は、釣竿の強度や剛性等を演出するものではない。むしろ、このような領域が存在することで、釣竿全体のしなやかな曲がり・撓りのバランスが損なわれてしまう恐れがある。
【００１３】
本発明の課題は、釣竿全体の長さを調整できる釣竿を提供するにあたり、その長さの変化の程度を自由に設定できる技術を提供することにある。
【００１４】
【課題を解決するための手段】
◎本発明に関するある釣竿は、筒状体である複数の竿体を順次連結してなる釣竿であって、穂先側端部内周面に嵌合雌部を有する元竿と、元竿内に穂先側に向かって出入自在に連結され、竿元側端部外周面に形成される第１嵌合雄部を有すると共に、穂先側の外周面に第２嵌合雄部を有する元上竿と、元上竿の第２嵌合雄部の穂先側に隣接する外周面に穂先側端部が連結され、元竿及び元上竿をその内部に収納可能に竿元側に延びる補助スリーブとを備える。
【００１５】
元上竿が元竿の穂先側に完全に引き出された延伸状態と、元上竿が元竿の内部に完全に収納された収納状態とにおいて、この元上竿と元竿とは相互に連結固定可能であり、各状態における具体的態様は以下の通りである。
【００１６】
まず、延伸状態においては、元竿の嵌合雌部と元上竿の第１嵌合雄部が相互に嵌着する。これらの嵌合部分が元上竿の元竿に対する抜け止めとなっているとともに、相互の竿体を連結固定する。一方、収納状態においては、元竿の嵌合雌部と元上竿の第２嵌合雄部が相互に嵌着する。そして、相互の竿体が連結固定される。
【００１７】
このような延伸状態及び収納状態の相互変換の際には、釣人は、一方の手でリールシート付近を把持しながら、他方の手で補助スリーブの竿元側外周面を把持して当該操作を行う。当該補助スリーブが元上竿の第２嵌合雄部より竿元側に延びることで、釣人は両手の間隔を過度に広げることなく当該操作が可能となる。また、元上竿を元竿から引き出した際の「引き出し長さ」を、補助スリーブの軸方向長さ分だけ大きく設定することができる。
【００１８】
◎本発明の別の釣竿は、筒状体である複数の竿体を順次連結してなる釣竿であって、軸方向中央付近の内周面に第１嵌合雌部を有すると共に、竿元側端部の内周面に第２嵌合雌部を有する元竿と、元竿内に穂先側に向かって出入自在に連結され、竿元側端部外周面に形成される嵌合雄部を有する元上竿と、元上竿の外周面にその穂先側端部が連結され、元竿及び元上竿をその内部に収納可能に竿元側に延びる補助スリーブとを備えている。
【００１９】
この元上竿と元竿とは、嵌合雄部が第１嵌合雌部に嵌着する延伸状態と、嵌合雄部が前記第２嵌合雌部に嵌着する収納状態とをとる。また、補助スリーブは、収納状態で元竿及び元上竿をその内部に収納しており、延伸状態で元上竿をその内部に収納し且つ竿元側端部において元竿の穂先側端部を覆っている。
【００２０】
元竿の第１嵌合雌部に元上竿の嵌合雄部が相互に嵌着した延伸状態では、嵌合部分が元上竿の元竿に対する抜け止めとなっているとともに、相互の竿体を連結固定している。この状態で、補助スリーブは元上竿の一部を内部に収納すると共に、元竿の穂先側端部をもカバーする。元竿と元上竿との外径差から生じ得る、延伸状態での元竿の穂先側端部と元上竿の周面との段差を補助スリーブが覆い隠し、その隙間へのゴミの侵入を抑え、見た目の悪さなども防ぐ。
【００２１】
一方、元竿の第２嵌合雌部と元上竿の嵌合雄部が相互に嵌着した収納状態でも、相互の竿体が連結固定される。この状態で、補助スリーブは元上竿と共に元竿も内部に収納する。
【００２２】
このような延伸状態及び収納状態の相互変換の際には、釣人は、一方の手でリールシート付近を把持しながら、他方の手で補助スリーブの外周面を把持して当該操作を行う。当該補助スリーブが元上竿の周面に竿元側に延びており、釣人は両手の間隔を過度に広げることなく当該操作が可能となる。また、元上竿を元竿から引き出した際の「引き出し長さ」を、任意の補助スリーブの軸方向長さに設定することができる。
【００２３】
◎本発明の他の釣竿は、筒状体である複数の竿体を順次連結してなる釣竿であって、穂先側端部内周面に嵌合雌部を有する元竿と、元竿内に穂先側に向かって出入自在に連結され、竿元側端部外周面に形成された第１嵌合雄部，及び軸方向中間の外周面に於いて隣接する部分より太径に形成された第２嵌合雄部を有する元上竿と、元上竿の第２嵌合雄部の穂先側に隣接する外周面に穂先側端部が連結され、元竿及び元上竿をその内部に収納可能に竿元側に延びる補助スリーブとを備えている。
【００２４】
この元上竿の穂先側端部より第２嵌合雄部までの領域は、第２嵌合雄部より竿元側の領域に比較して厚肉であり且つ曲げ剛性が高い。元上竿と元竿とは、嵌合雄部が第１嵌合雌部に嵌着する延伸状態と、嵌合雄部が第２嵌合雌部に嵌着する収納状態とをとる。そして、補助スリーブは、収納状態で元竿及び元上竿をその内部に収納しており、延伸状態で元上竿をその内部に収納し且つ竿元側端部において元竿の穂先側端部を覆っている。
【００２５】
この元上竿は、元竿との関係において、第１嵌合雄部と第２嵌合雄部とがそれぞれ収納状態と延伸状態とで元竿に嵌着する。この場合、第２嵌合雄部より竿元側の領域は、元竿の外部に露出することなく常に元竿内に位置し、収納状態において元竿の竿元側端部との嵌着のためにのみ用いられる部分となる。この領域は、穂先側の領域に比較して肉薄且つ曲げ剛性が低くなっており、釣竿全体の撓りのバランスが損なわれることがない。
【００２６】
なお、元上竿の穂先側端部より第２嵌合雄部までの領域には先細りテーパが施されており、元上竿の第２嵌合雄部より竿元側の領域は、その穂先側端部より第２嵌合雄部までの領域に比較して小径であるように設定してもよい。
【００２７】
このように設定した場合、延伸状態及び収納状態の何れかにおいて、外部に露出して釣竿全体の剛性の変化乃至バランスを演出する部分である穂先側端部より第２嵌合雄部までの領域は、一般的な先細りテーパ部分となる。他方、第２嵌合雄部より竿元側の領域は、穂先側端部より第２嵌合雄部までの領域に比較して小径として、可及的にその釣竿全体のバランスへの寄与を抑えている。
【００２８】
さらにまた、元上竿の第２嵌合雄部より竿元側の領域は、穂先側端部より第２嵌合雄部までの領域に比較して一段小径となるように設定してもよい。
【００２９】
このように所定の領域を一段小径に設定することで、元上竿の第２嵌合雄部より竿元側の領域の釣竿全体へのバランスの寄与を最小限度に抑え得ることになる。
【００３０】
◎また、本発明のさらに別の釣竿は、上述の元竿及び元上竿に加えて、元上竿内に穂先側に向かって出入自在に連結される中竿と、中竿内に穂先側に向かって出し入れ自在に連結される穂先竿とをさらに備えている。
【００３１】
この穂先竿は、本体部及び本体部の竿元側端部に形成される連結部を有する中実竿体と、中実竿体の連結部が挿入される受け部が穂先側端部に形成されており連結部が受け部に挿入されて接着固定されている中空竿体とからなる。この中実竿体の連結部は、竿元側ほど小径化するテーパの施されたテーパ部とテーパ部の竿元側に延びる軸方向において径の変化しない延伸部とを有し、中実竿体の本体部と連結部のテーパ部との臨界及び／又は延伸部の竿元側端部が外方向に膨らむ曲面となっている。また、受け部の穂先側端部内面はテーパ部に合致するテーパ面となっている。
【００３２】
このような釣竿の穂先竿は、中空竿体内に挿入されている中実竿体の連結部において、所定の部分を曲面化している。仕掛けに魚が係るなどして釣竿全体が大きく撓り、穂先竿においても、中実竿体と中空竿体とが大きく撓み、連結部と中空竿体の受け部の内周面との接触部分に大きな負荷がかかっても、連結部の径の変化する部分であって、外側に突出する部分が曲面化されており、これらの部分から受け部若しくは連結部の破損が進行し難くなっている。
【００３３】
なお、連結部の延伸部には、テーパ部より緩やかに竿元側ほど小径化するテーパを施しても良い。このようなテーパを施した場合、当該釣竿の穂先竿では、延伸部をテーパ面として中空竿体内周面への接触を可及的に抑え、中実竿体途中空竿体との連結力は、専らテーパ部における接着に委ねることになる。延伸部の中空竿体内での自由度をある程度確保することで、受け部若しくは連結部への負荷がかかった際の両者の破損の進行を抑えている。
【００３４】
さらに、この中実竿体は連結部付近において竿元側端面から穂先側方向に向かって空間が形成されていてもよい。このような中実竿体の連結部付近の空間が、中実竿体の自由度をある程度確保し、受け部若しくは連結部へ負荷がかかった際の両者の破損の進行を抑える。
【００３５】
なお、この種の釣竿の穂先竿では、中実竿体と中空竿体との連結部分の周面をゴム系塗料でさらにコーティングしてもよい。このゴム系塗料が、応力が集中しがちな中実竿体と中空竿体との連結部分、特に、両竿体の連結部分の周面の微妙なズレ等を吸収し、表面塗料層でのクラックの発生を抑える。
【００３６】
また、補助スリーブの周面にリールを脱着自在に装着可能なリールシートを配置してもよい。
【００３７】
◎本発明のさらに他の釣竿は、中竿及び穂先竿の周面に軸方向にスライド移動可能に配置される複数のスライドガイドと、補助スリーブ上にスライド移動可能に配置されるスリーブ用ガイドと、各竿体を収納する際に用いられるトップカバーとをさらに備えている。
【００３８】
このトップカバーは、穂先竿及び中竿を元上竿内に収納した収納状態において元上竿の穂先側端部周面に当接される装着基部と、装着基部の穂先側に連続して形成され複数のスライドガイドを囲繞保持するガイド保護部と、装着基部の竿元側端部に設けられスリーブ用ガイドを保持する保持部とを有している。
【００３９】
この構成によれば、釣竿が収納状態となったとき、各スライドガイドは釣竿の軸方向に沿って各竿体の穂先側に整列される。この状態で、装着基部が元上竿の先端部周面に沿って配置されると、各スライドガイドはガイド保護部によって囲繞保持される。また、装着基部が元上竿の先端部周面に配置されると、スリーブ用ガイドも穂先側にスライド移動し、保持部がスリーブ用ガイドに係合する。これにより、スリーブ用ガイドは、釣竿に対する所定の位置に位置決め保持されることになる。
【００４０】
また、スリーブ用ガイドは、補助スリーブの周面に嵌め合わされる環状部を有するフレームとフレームに装着されるガイドリングとを有し、保持部は、元上竿の穂先側の周面と環状部の内周面との間に圧入される挿入部分を有するような構造としてもよい。
【００４１】
この場合、スリーブ用ガイドは、そのフレームの円環部が補助スリーブに嵌め合わされることによって位置決めされ補助スリーブに係合される。
【００４２】
釣竿が収納状態となった際、スリーブ用ガイドは、補助スリーブの穂先側へスライド移動されて元上竿の穂先側の周面に至る。元上竿は補助スリーブよりもその外径が後端部の外径よりも小さく設定されているので、スリーブ用ガイドが先端部側へスライド移動されると、円環部の内周面と元上竿の周面との間に所定の隙間が形成される。この隙間に挿入部材が挿入され、これにより、スリーブ用ガイドが位置決め固定され、トップカバーに装着されることになる。
なお、保持部の挿入部分は弾性ゴムから構成してもよい。
【００４３】
◎また、本発明に関する釣竿では、以下のような別の穂先竿を用いても良い。この別の穂先竿は、本体部及び本体部の竿元側端部に形成される連結部を有する中実竿体と、中実竿体の連結部が挿入される受け部が穂先側端部に形成されており連結部が受け部に挿入されて接着固定されている中空竿体とからなる。
【００４４】
この中実竿体の連結部は、竿元側ほど小径化するテーパの施されたテーパ部とテーパ部の竿元側に延びる軸方向において径の変化しない延伸部とを有している。一方、中空竿体の穂先側の内面は、穂先側端部から形成されるテーパ部に合致する竿元側ほど小径化する第１テーパ面と、第１テーパ面の竿元側に連続する延伸部より軸方向長さが短い軸方向範囲において径の変化しないストレート面と、ストレート面の竿元側に連続する竿元側ほど大径化する第２テーパ面とを有している。
【００４５】
このような釣竿の穂先竿では、中空竿体内に挿入されている中実竿体の連結部が、以下のように受け部に当接している。まず、連結部のテーパ部は受け部の第１テーパ面に当接している。連結部の延伸部は受け部のストレート面に当接している。そして、連結部の延伸部の竿元側端部は、ストレート面より竿元側にはみ出して、受け部の第２テーパ面には接触していない。
【００４６】
仕掛けに魚が係るなどして釣竿全体が大きく撓り、穂先竿においても、中実竿体と中空竿体とが大きく撓み、連結部と中空竿体の受け部の内周面との接触部分に大きな負荷がかかっても、連結部の竿元側端縁は受け部に直接接触していないので、この連結部の竿元側端縁に応力が集中して、連結部の竿元側端縁から受け部若しくは連結部の破損が進行し難い。
【００４７】
【発明の実施の形態】
［第１実施形態］
以下、本発明の第１実施形態について図面を参照しつつ説明する。
【００４８】
（釣竿全体の構造）
本発明の第１実施形態を採用した釣竿は、図１に示すように、周面にリール（図示せず）を脱着自在に装着可能なリールシート６を有する元竿１と、元竿１の穂先側に順次振出形式で連結される、元上竿２，第１中竿３，第２中竿４及び穂先竿５とを有している。これら元竿１〜穂先竿５は炭素繊維またはガラス繊維等に合成樹脂を含浸させたプリプレグ素材から形成される先細り筒状部材である。これらはいわゆる振出形式で連結されており、元上竿２〜穂先竿５は穂先側から順次竿元側の竿体の内部に挿入され出し入れ自在である。また、元上竿２には補助スリーブ１５が装着されている。
【００４９】
これらの元上竿２〜穂先竿５を穂先側に引き出した際には、それぞれの竿体が、穂先側に位置する竿体の竿元側端部外周面と竿元側に位置する竿体の穂先側端部内周面とで相互に嵌着し、穂先側への抜け止め且つ相互の連結固定が可能となっている。この状態で、釣人はこの釣竿を用いて釣りをおこなうことになる。一方、釣りを終えた際には、穂先竿５から順次竿元側の竿体内に竿体を収納してコンパクトな状態とする。さらに、特に、元上竿２と元竿１とにあっては、後述のように、延伸状態，収納状態の何れの状態にあっても、相互に連結固定可能となっており、釣竿全体の長さを調整しながら釣りをおこなうことができる。
【００５０】
また、第１中竿３，第２中竿４，穂先竿５には、最も穂先側に配置され軸方向に移動不能に固定されている固定ガイド９と、その竿元側の周面に軸方向に移動自在且つ所定の位置に置いて係止可能に配置された複数のスライドガイド１０が必要に応じて配置されている。穂先竿５に於ける固定ガイド９はトップガイドである。スライドガイド１０は、小径化する各竿体の周面において所定の軸方向位置で竿体の周面に嵌着し、且つ、穂先側に向かってスライド移動可能である。
【００５１】
さらに、補助スリーブ１５の周面にもスリーブ用ガイド１６が配置される。スリーブ用ガイド１６も上述のスライドガイド１０と同様に、補助スリーブ１５の周面に軸方向に移動自在且つ所定の位置に置いて係止可能に配置される。補充スリーブ１５からさらに穂先側へもスライド移動可能である。
【００５２】
なお、この実施形態においては、竿体の本数を５本としているが、竿体の数は任意に設定するものであり、これに限定されるものではない。
【００５３】
（元竿１と元上竿２について）
次に、元竿１と元上竿２との連結構造について、詳しく説明する。図２及び図３に於いて模式的に示すように、元竿１及び元上竿２はそれぞれ一定の先細りテーパが施された筒状体である。
【００５４】
この元竿１の竿元側端部には脱着自在に底栓７が装着されている。元竿１は内部に元上竿２が収納可能な筒状体であり、その穂先側端部外周縁には必要に応じて保護用の金属リングが装着される。また、穂先側端部の内周面が嵌合雌部１ａとなっている。この嵌合雌部１ａは他の部分に比べて必要に応じて小径化して形成する部分である。
【００５５】
一方、元上竿２は、竿元側端部外周面に形成された第１嵌合雄部２ａと、その穂先側の外周面に形成された第２嵌合雄部２ｂとを有している。これらの各部分は、元上竿２の筒状部分と一体的に以下のようにして形成されている。即ち、この元上竿２は上述のように炭素繊維等の強化繊維に合成樹脂を含浸させてなるプリプレグ素材を焼成して筒状に形成するものである。このような筒状体を製造する際に、必要な所定の箇所に補助用プリプレグ素材を筒状体形成用プリプレグ素材の外周面に巻回しておき、これらの各素材を全体として焼成する。なお、この際に用いる補助用プリプレグは竿体の軸方向に強化繊維が配向されたものを用いるのが好ましい。
【００５６】
従って、この釣竿の元竿１と元上竿２とは、後述のように、元上竿２を元竿１の穂先側に引き出した延伸状態（図３(b)参照）と、元上竿２を元竿１内に収納した収納状態（図３(a)参照）との何れにおいても、相互に連結固定し得る。
【００５７】
一方、補助スリーブ１５は、元竿１より大径の筒状部材である。元竿１などの各竿体と同様に所定のプリプレグ素材を焼成して形成しても、硬質合成樹脂若しくは金属等から形成してもよい。この補助スリーブ１５は、元上竿２の第２嵌合雄部２ｂの穂先側に隣接する外周面に穂先側端部が連結され、元竿１及び元上竿２の第２嵌合雄部２ｂより竿元側をその内部に収納可能に竿元側に延びている。この補助スリーブ１５の元上竿２への固定方法は周知の方法を用いれば足りる。この実施形態では、補助スリーブ１５を接着などによって元上竿２の周面に固定した例を示している。もっとも、例えば、元上竿２の所定位置の周面に雌ねじ部分を形成し、補助スリーブ１５を螺着させる手法を採用して、補助スリーブ１５を元上竿２より取り外し可能としても良い。
【００５８】
なお、この補助スリーブ１５の軸方向長さは任意に設定可能であるが、少なくとも、元竿１の穂先側端部からリールシート６迄の長さより短く設定される。その外周面には、ユーザが把持しやすいように滑り止め用の凹凸を設けたり、ウレタンゴム等からなるグリップを配置してもよい。
【００５９】
補助スリーブ１５上に配置されるスリーブ用ガイド１６は、脚を構成するフレーム４０と、ガイドリング４１とを備えている。フレーム４０は、環状部４２を有し、この環状部４２が補助スリーブ１５の外側に嵌め込まれている（図１０参照）。
【００６０】
環状部４２の内径寸法は、補助スリーブ１５の所定の軸方向位置の外径寸法に対応されている。スリーブ用ガイド１６が補助スリーブ１５上の所定に位置へスライドされることによって、環状部４２の内径と補助スリーブ１５の外径との関係（はめあい）によって、所定の位置に固定される。また、スリーブ用ガイド１６は穂先側に向かってスライド移動も可能となっている。定位置に固定されるようになっている。
【００６１】
（元上竿２と元竿１との操作について）
このように構成される釣竿では、穂先竿５より順次各竿体を穂先側に引き出して一本の長い竿体にして釣りをおこなう。釣りを終えた後は、穂先竿５より順次各竿体を竿元側の竿体内部に収納してコンパクトな状態とする。さらに、元上竿２が元竿１の穂先側に完全に引き出された状態（延伸状態）と、元上竿２が元竿１の内部に完全に収納された状態（収納状態）とにおいて、この元上竿２と元竿１とは相互に連結固定可能であり、釣竿全体の長さを調整して釣りができる。即ち、５つの竿体の全てを伸ばした状態と４本分のみ伸ばした状態との何れにおいても魚釣りを行うことができるのである。この各状態における具体的態様は以下の通りである。
【００６２】
延伸状態においては、図３（ｂ）に示すように、元竿１の嵌合雌部１ａと元上竿２の第１嵌合雄部２ａが相互に嵌着する。一方、収納状態においては、図３（ａ）に示すように、元竿１の嵌合雌部１ａと元上竿２の第２嵌合雄部２ｂが相互に嵌着する。そして、このような延伸状態及び収納状態の相互変換の際には、釣人は、図２に示すように、一方の手でリールシート付近等を把持しながら、他方の手で補助スリーブ１５の竿元側外周面を把持して、元上竿２の出し入れの操作を行う。この補助スリーブ１５が元上竿２の第２嵌合雄部２ｂより竿元側に延びることで、釣人は両手の間隔を過度に広げることなく、元上竿２の出し入れの操作が可能となる。また、元上竿２を元竿１から引き出した際の「引き出し長さ」を、補助スリーブ１５の軸方向長さ分だけ大きく設定することも可能となる。
【００６３】
（穂先竿５について）
次に、穂先竿５の構造について説明する。
【００６４】
図４に示すように、穂先竿５は、穂先側の中実竿体９２と竿元側の中空竿体９１とを連結し接着固定して一本の竿体としたものである。穂先竿５では、その穂先側端部（即ち、中実竿体９２の穂先側端部）には上述の固定ガイド９（トップガイド）が装着されており、その竿元側端部（即ち、中空竿体９１の竿元側端部）には他の竿体と連結するための嵌着部分９１ａが形成される。さらに、軸方向に間隔を隔てて複数のスライドガイド１０も装着されている。
【００６５】
中実竿体９２は、全体として穂先側ほど小径化するテーパが施された棒状・中実のソリッド体である。例えば、炭素繊維を軸方向に引き揃え熱硬化性樹脂を含浸させた炭素繊維強化樹脂を加圧加熱して形成される。そして、図５に示すように、この中実竿体９２の竿元側端部には他の部分より小径に連結部９３が形成されている。この連結部９３は、竿元側ほど急激に小径化する逆テーパ部Ｘ１とその竿元側に連続して形成され軸方向において径の変化しない延伸部Ｙ１との２段階構造となっている（図６参照）。例えば、１つの例を示すと、中実竿体９２の最大外径は２．１０ｍｍ程度とする。そして、逆テーパ部Ｘ１はそのテーパ率は５０／１０００程度に設定される。逆テーパ部Ｘ１の軸方向長さは任意に設定可能であるが、１０ｍｍ程度の長さとするのがよい。延伸部Ｙ１は軸方向において径の変化がない若しくは殆ど径の変化が認められない部分である。延伸部Ｙ１の外径は１．５５〜１．５８ｍｍ程度とし、その軸方向長さも上述の逆テーパ部Ｘと同様に１０ｍｍ程度の長さ若しくはそれ以上の長さ（例えば、１５mmとするのがよい。
【００６６】
図６に示すように、この連結部９３において、中実竿体９２の連結部９３以外の部分（本体部）と連結部９３の逆テーパ部Ｘ１との臨界Ｐ１と、延伸部Ｙ１の竿元側端部Ｐ２とがそれぞれ外方向に膨らむ曲面（Ｒ面）となっている。この曲面は連結部９３を形成後に研磨などして形成すれば足りる。なお、ここでは、Ｐ１，Ｐ２の何れにおいても曲面化を施しているが、何れか任意の一方のみを曲面化してもよい。
【００６７】
一方、中空竿体９１は、全体として穂先側ほど小径化するテーパが施された先細り筒状部材である。炭素繊維強化樹脂等の素材を焼成して形成されている。穂先側端部の内周が上述の連結部９３を受ける受け部９４となっている。この受け部９４は、上述の連結部９３の逆テーパ部Ｘ１及び延伸部Ｙ１に対応するようにその内径が設定されて２段テーパ構造となる。この受け部９４はリーマ加工などによって形成され、その内径は、延伸部Ｙ１の外径１．５５〜１．５８ｍｍ程度に対してやや大きめに、１．５７〜１．６０ｍｍ程度に設定する。接着剤を隙間に介在させるためである。
【００６８】
この中実竿体９２と中空竿体９１とは、連結部９３を受け部９４に穂先側から挿入した上で接着剤によって接着固定される。その上で、図５に示すように、中実竿体９２と中空竿体９１との境界面部分から軸方向に一定の範囲で、ゴム系塗料９５がその両竿体の周面に塗布される。ゴム系塗料９５の塗布後には、さらに、穂先竿５の周面全体に周面塗装を施し、中実竿体９２と中空竿体９１との連結部分が外部より認識し得ないようにしてもよい。
【００６９】
このような穂先竿５は、上述のように、中空竿体９１内に挿入されている中実竿体９２の連結部９３において、所定の部分を曲面化している。仕掛けに魚が係るなどして釣竿全体が大きく撓り、穂先竿５においても、中実竿体９２と中空竿体９１とが大きく撓み、連結部９３と中空竿体９１の受け部９４の内周面との接触部分に大きな負荷がかかっても、連結部９３の径の変化する部分であって、外側に突出する部分が曲面化されており、これらの部分から受け部９４若しくは連結部９３の破損が進行し難くなっている。
【００７０】
なお、この実施形態では、このような特殊な穂先竿５を利用しているが、その他の一般的な穂先竿５を用いることも可能である。
【００７１】
（トップカバー２０について）
続いて、本発明の釣竿において、各竿体を収納してコンパクトに収納した状態を説明する。
図７〜１０に示すように、本発明の釣竿を構成する各竿体を竿元側の竿体内に収納した状態で、元上竿２の穂先側にトップカバー２０が装着される（特に、図１０参照）。このトップカバー２０は、釣竿を構成する竿体及び各種の釣糸ガイド（スライドガイド１０等）を略位置決め状態で保持し、搬送時等における釣糸ガイド等の損傷を防止するためのものである。
【００７２】
このトップカバー２０は、装着基部２１と、ガイド保護部２２と、保持部２３とを備えている。装着基部２１とガイド保護部２２とはポリカーボネイトなどの合成樹脂から一体的に形成されている。
【００７３】
装着基部２１は、トップカバー２０が釣竿に装着される際に、各竿体が収納された元上竿２の穂先側の周面に当接するように配置される。この装着基部２１は真直な板状に形成されており、この部分が元上竿２の先端部周面に沿ってその軸方向に沿って配置される。また、装着基部２１の内面２４は、湾曲面に形成されている。この内面２４の曲率半径は、釣竿の先端部の外径寸法に対応されている。したがって、装着基部２１は安定した状態で元上竿２の周面に接触する。
【００７４】
ガイド保護部２２は、図７に示すように、細長筒状に形成されている。このガイド保護部２２は、装着基部２１が元上竿２の先端部周面に取り付けられた状態で、各釣糸ガイド（スライドガイド１０や固定ガイド９）を囲繞して保護している。
【００７５】
また、ガイド保護部２２は、ガイド支持部材２５を備える。このガイド支持部材２５は、細長棒状（針状）に形成されている。ガイド支持部材２５は、ガイド保護部２２の底面にいわゆる片持ち状に固定されており、ガイド保護部２２の長手方向に沿って延びている。
【００７６】
このガイド支持部材２５は、例えば、樹脂若しくは屈曲自在な金属線などにより構成される。ガイド支持部材２５は、各釣糸ガイドに挿通されるようになっており、ガイド支持部材２５が挿通されることによって、各釣糸ガイドは、略位置決め状態で保持される。なお、ガイド支持部材２５の先端部には小孔２６が設けられており、釣糸が各釣糸ガイドに挿通される際のいわゆる糸通しとして利用することもできる。
【００７７】
装着基部２１は、さらに固定バンド２７を有している。この固定バンド２７は、例えばゴムにより構成され、薄肉帯状に形成されている。固定バンド２７は、その基端部が装着基部２１に固定されており、また、その先端部には、貫通孔３０が設けられている。一方、装着基部２１の外面２８には、突起２９が突設されている。
【００７８】
この固定バンド２７は、装着基部２１が釣竿の先端部周面に沿わされた状態で、両者に巻き回され、固定バンド２７の上記貫通孔３０に上記突起２９が嵌め込まれる。これにより、装着基部２１は、釣竿に締結され、確実に固定される。
【００７９】
保持部２３は、例えばゴムにより構成される。もっとも、保持部２３を構成する材料は、ゴムに限定されるものではなく、樹脂等により構成されていてもよい。ただし、保持部２３は、ゴム等の弾性に富む材料で構成されるのが好ましい。この保持部２３は、全体として細長板状に形成されており、基部３１と挿入部３２（挿入部材）とを備えている。
【００８０】
基部３１は、上記装着基部２１の内面２４に沿って配置されている。基部３１は、例えば、接着剤や両面テープ等によって装着基部２１に固着されている。
【００８１】
挿入部３２は、本実施形態では、基部３１と一体的に形成されており、基部３１に連続して装着基部２１の長手方向に延びている。挿入部３２の先端部の厚み寸法ｄは、所定の寸法に設定されており、釣竿の仕様に応じて適宜１．５ｍｍ〜６．０ｍｍの範囲で設定され得る。
【００８２】
この挿入部３２は、いわゆる楔状に形成されている。具体的には、挿入部３２の下面３３は、上面３４に対して傾斜しており、これにより、挿入部３２の厚み寸法は、先端部から基部３１側に向かって漸次大きくなるように設定されている。なお、挿入部３２の最大厚み寸法は、３ｍｍ〜８ｍｍの範囲で設定され得る。
【００８３】
なお、このトップカバー２０では、挿入部３２は、基部３１と一体的に形成されているが、挿入部３２が別部材として構成され、基部３１に連結されていてもよい。その場合、挿入部３２は、ゴム等の弾性に富む材料で構成されるのが好ましい。
【００８４】
（トップカバー２０の装着方法）
次に、本発明の釣竿の各竿体を収納した収納状態において、このトップカバー２０を元上竿２に装着する手順を説明する。
【００８５】
図１０に示すように、釣りを終えたユーザは、穂先竿５，第２中竿４，第１中竿３の周面に配置されているスライドガイド１０を順次穂先側にスライド移動させた上で、穂先側の竿体から元上竿２までを順次元竿１内に収納する。そして、ユーザはトップカバー２０の装着基部２１を元上竿２の穂先側周面に沿って当接させつつガイド保護部２２内に穂先竿５等を収納する。さらに、ユーザはガイド支持部材２５に各釣糸ガイド（固定ガイド９及びスライドガイド１０）を挿通させる。
さらに、ユーザは補助スリーブ１５上のスリーブ用ガイド１６を穂先側にスライド移動させて、元上竿２の周面へとスリーブ用ガイド１６を導く。スリーブ用ガイド１６の環状部５２の内周面と元上竿２の外周面との間には、径差から所定の隙間が形成されることになる。そして、この隙間に保持部２３が係合する。つまり、スリーブ用ガイド１６は、保持部２３によって位置決めされて保持される。
【００８６】
［第２実施形態］
本発明の第２実施形態について、図１１を参照しつつ説明する。
釣竿全体の一般的な構造は上記第１実施形態と同様であり、先細りテーパの施された元竿５１と元上竿５２とは延伸状態・収納状態の何れにおいても相互に連結固定可能である。
【００８７】
この元竿５１の周面には、上記第１実施形態と同様に、リールシート６が配置される。また、竿元側端部には、尻栓７が脱着自在に装着されると共に、この底栓７の穂先側に隣接して元竿５１の内部にストッパーリング５３（第２嵌合雌部に相当する）が配置されている。このストッパーリング５３は軸方向に貫通する円筒型部材であり、内周面に径内方向に突出する複数の突起が周方向に間隔を隔てて軸方向に延びている。このストッパーリング５３は元竿５１の竿元側端部から挿入され、例えば、接着剤等で固定される。必要に応じて取り外し可能にしてもよい。そして、この突起に後述の元上竿５２の嵌合雄部５２ａが穂先側から挿入されて嵌着する（図１１（ｂ）参照）。
【００８８】
また、元竿１の軸方向中央付近の内周面も、後述の元上竿５２の嵌合雄部５２ａが嵌着する部分であり、第１嵌合雌部５１ａとなっている（図１１（ａ）参照）。第１嵌合雌部２１ａは、他の部分より別途内径を小径化させてもよいが、元竿５１のテーパと後述の元上竿５２の嵌合雄部の外径との関係によって、元竿５１の所定の軸方向位置の内周面に嵌着し得るようにしてもよい。この第１嵌合雌部５１ａとストッパーリング５３との軸方向距離が「引き出し長さ」に相当する。適当な「引き出し長さ」としては５００〜６００ｍｍ程度である。
【００８９】
元上竿５２も上記第１実施形態と同様の先細りテーパの施された筒状体である。竿元側端部に他の部分より大径化された嵌合雄部５２ａが設定される。この嵌合雄部５２ａが元竿５１の所定の部分に嵌着し得ることは既に説明したとおりである。
【００９０】
この元上竿５２の周面にも補助スリーブ１５が配置される。補助スリーブ１５は、元竿２１より大径の筒状部材である。上記第１実施形態と同様に、所定のプリプレグ素材を焼成して形成しても、硬質合成樹脂より形成してもよい。
【００９１】
この補助スリーブ１５の装着位置は以下の通りである。
元竿５１の第１嵌合５１ａに元上竿５２の嵌合雄部５２ａが嵌着する延伸状態（図１１（ａ））において、補助スリーブ１５の竿元側端部が元竿５１の穂先側端部を覆うような位置で、補助スリーブ１５の穂先側端部が元上竿５２の外周面に連結される。この補助スリーブ１５の軸方向長さは、元竿５１の穂先側端部からリールシート６迄の長さより短く設定する必要がある。結果的には、補助スリーブ１５の軸方向長さが上述の「引き出し長さ」に相当することになる。
【００９２】
このように構成される釣竿においても、延伸状態・収納状態の何れにおいても、元上竿５２と元竿５１とを相互に連結固定可能であり、釣竿全体の長さを調整して釣りができる。このような延伸状態及び収納状態の相互変換の際には、釣人は、第１実施形態と同様に、一方の手でリールシート付近等を把持しながら、他方の手で補助スリーブ１５の竿元側外周面を把持して、元上竿５２の出し入れの操作を行うことができる。
【００９３】
特に、図１１（ａ）に示すような延伸状態において、補助スリーブ１５が元上竿５２の一部を内部に収納すると共に、元竿５１の穂先側端部をもカバーする。そして、元竿５１と元上竿５２との外径差から生じ得る、延伸状態での元竿５１の穂先側端部と元上竿５２の周面との段差を補助スリーブ１５が覆い隠し、その隙間へのゴミの侵入を抑え、見た目の悪さなども防ぐ。また、元上竿５２を元竿５１から引き出した際の「引き出し長さ」を、任意の補助スリーブ１５の軸方向長さに設定することができる。即ち、「引き出し長さ」に関する設計の自由度が向上する。
【００９４】
［第３実施形態］
さらに、第２実施形態の変形例として、第３実施形態を図１２に模式的に示す。
この釣竿における元竿５１と元上竿５２との連結構造は上記第２実施形態と同様である。即ち、元竿５１は竿元側端部にストッパーリング（図示せず）を備え、軸方向中央付近の内周面を第１嵌合雌部５１ａとしている。一方の、元上竿５２は竿元側端部に嵌合雄部５２ａを有する。そして、上記第２実施形態において説明するような位置において元上竿５２の周面に補助スリーブ１５が連結されている。
【００９５】
この釣竿では、リールシート６が補助スリーブ１５の周面に配置されている。リールシート６は周知の別部材を装着すれば足りる。例えば、巻糸などでリールシート６を巻回して樹脂コーティングなどを施す。若しくは、補助スリーブ１５の周面にパイプ状のリールシート６を配置して一体成型しても良い。
【００９６】
このように補助スリーブ１５上にリールシート６を配置すると、図１２に示すように、延伸状態・収納状態相互の状態変化により、リールシート６から釣竿の竿元側端部までの長さを相対的に変化する。釣り操作の状況にあわせて、このリールシート６から釣竿の竿元側端部までの長さを変化させることで、釣人が好みのリールシート６位置で釣り操作を行うことが可能となる。例えば、延伸状態として、脇に元竿５１を挟み込みながら釣り操作をおこなうようなことも可能である。
【００９７】
［第４実施形態］
以下、本発明の第４実施形態について図面を参照しつつ説明する。
（釣竿の構造）
本発明の第４実施形態を採用した釣竿の基本的な構造は、第１実施形態と同様である。元竿６１と元上竿６２とが、以下のような構造になっている。
【００９８】
図１３及び図１４に示すように、元竿６１は一定の先細りテーパが施された筒状体である。この元竿６１の竿元側の周面にはリールを取り付けるためのリールシート６が、また、竿元側端部には脱着自在に尻栓７が装着されている。この点は、上記第１実施形態と同様である。また、穂先側端部外周縁には嵌合リング７１が装着されている。嵌合リング７１は元上竿６２の延伸状態において補助スリーブ１５の竿元側端部と嵌着し、がた止め作用を奏する（図１４参照）。一方、元竿６１の竿元側端部内周面はねじ溝が形成され、ここに尻栓７が螺着している。この尻栓７は元上竿６２の竿元側端部を収納し内嵌可能な嵌合雌部を有する（図１３参照）。
【００９９】
元上竿６２も必要な先細りテーパの施された筒状体である。竿元側端部外周面に隣接する部分より太径に形成された第１嵌合雄部６２ａを有する。また、その穂先側の外周面にも隣接する部分より一段太径に第２嵌合雄部６２ｂが形成され、さらに、その穂先側の外周面にも隣接する部分より一段太径の太径部６２ｃが形成されている。これらの各部分は、後に詳しく説明するように、元上竿６２の筒状部分と一体的に所定のプリプレグ素材から形成されている。この第１嵌合雄部６２ａは収納状態において上述の元竿６１の尻栓７の嵌合雌部に、第２嵌合雄部６２ｂは延伸状態において元竿６１の穂先側端部内周面に嵌着する部分である（図１３・図１４参照）。
【０１００】
この元上竿６２は、詳しくは、穂先側端部より第２嵌合雄部６２ｂまでの領域は高剛性の先細り筒状体であり、第２嵌合雄部６２ｂより竿元側の領域はその穂先側より一段低剛性・小径のものである。第２嵌合雄部６２ｂより竿元側の領域は軸方向において径の変化のない部分としてもよい。
【０１０１】
補助スリーブ１５は、上記第１実施形態と同様に、元竿６１より大径の筒状部材である。元竿６１などの各竿体と同様に所定のプリプレグ素材を焼成して形成しても、硬質合成樹脂若しくは金属素材から形成してもよい。この補助スリーブ１５は、元上竿６２の第２嵌合雄部６２ｂの穂先側に隣接する外周面に形成された太径部６２ｃにおいて、その穂先側端部が元上竿６２に連結固定され、元竿６１及び元上竿６２をその内部に収納可能に竿元側に延びている。この補助スリーブ１５の元上竿６２への固定方法は周知の方法を用いれば足り、例えば、接着，ねじ螺合などの手法を採用すれば足りる。この点も第１実施形態と同様である。
【０１０２】
（元上竿６２の製造方法）
次に、上述の元上竿６２の製造方法を具体的に説明する。
図１５（ａ）に示すように、まず、芯材１００に必要な離型材などを塗布し、芯材１００の周面に周方向プリプレグシートＰ１を巻回する。この周方向プリプレグシートＰ１は、芯材１００の周方向に強化繊維が配向されるように、炭素繊維やガラス繊維を引き揃えた上にエポキシ樹脂などを含浸させたプリプレグ素材をシート状に加工したものである。この周方向プリプレグシートＰ１は、それぞれ巻回長さを穂先側及び竿元側において１プライとなるように設定する。芯材１００に一定のテーパが施されている場合には、穂先側の辺と竿元側の辺との長さがそのテーパ分異なることになる。なお、ここでは、周方向プリプレグシートＰ１を用いた場合を例示しているが、テープに加工したプリプレグ素材を用いてもよい。この場合には、テープの長手方向に強化繊維を配向する。そして、テープ状のプリプレグ素材を芯材１００に対して螺旋状に隙間なく巻回してゆく。
【０１０３】
次に、図１５（ｂ）に示すように、軸方向プリプレグシートＰ２を巻回する。この軸方向プリプレグシートＰ２は、２種類のプリプレグシートを貼り合わせて連結したものである。即ち、軸方向プリプレグシートＰ２は、穂先側に配置される高弾性率の強化繊維に合成樹脂を含浸させた第１軸方向プリプレグ素材Ｐ２ａと、竿元側に配置される低弾性率の強化繊維に合成樹脂を含浸させた第２軸方向プリプレグ素材Ｐ２ｂとを連結して構成されている。
【０１０４】
第１軸方向プリプレグ素材Ｐ２ａは、強化繊維として炭素繊維を用いその引張弾性率が40t/mm2であり、且つ、その炭素繊維が芯材１００の軸方向に引き揃えて配向されている。その形状は、穂先側を短辺に、竿元側を長辺とするような略台形型である。詳しくは、穂先側の短辺が３プライ分、竿元側の長辺が４プライ分の巻回長さを有している。もっとも、この実施形態では、後述のように第２軸方向プリプレグ素材Ｐ２ｂとの連結部分を斜行させているので、長辺側部分の一部は斜めに切り欠かれている。第１軸方向プリプレグ素材Ｐ２ａとしては、このような斜めの切り欠き部分を形成することなく、略台形型のままのものを用いても良い。なお、この第１軸方向プリプレグ素材Ｐ２ａの略台形型の高さ（軸方向長さに相当）は、元上竿６２の穂先側端部から第２嵌合雄部６２ｂまでの長さに対応する。
【０１０５】
第２軸方向プリプレグ素材Ｐ２ｂは、強化繊維として炭素繊維を用いその引張弾性率が20t/mm2であり、且つ、その炭素繊維が芯材１００の軸方向に引き揃えて配向されている。その形状は、穂先側，竿元側の両辺を原則として同じくする略矩形型である。詳しくは、芯材１００のテーパにあわせて穂先側の短辺が２プライ分、竿元側の長辺も２プライ分の巻回長さを有するように設定するので、両者の長さは完全に一致するものではない。もっとも、この実施形態では、第１軸方向プリプレグ素材Ｐ２ａとの連結部分を斜行させているので、穂先側の辺の一部は斜めに穂先側に張り出している（上記第１軸方向プリプレグ素材Ｐ２ａの切り欠き部分に相当）。第１軸方向プリプレグ素材Ｐ２ａとして、このような斜めの切り欠き部分を形成することなく、略台形型のままのものを用いた場合には、第２軸方向プリプレグ素材Ｐ２ｂも略矩形型のままとなる。
【０１０６】
このような２種類の軸方向プリプレグ素材を斜行した部分で貼り合わせて連結し、１つの軸方向プリプレグシートＰ２としたものを上述の周方向プリプレグシートＰ１の外周に巻回する。なお、両者の連結の際には、巻回開始側を揃えて（図１５（ｂ）の下側の辺）連結する。
【０１０７】
続いて、図１５（ｃ）に示すように、軸方向プリプレグシートＰ２の外周の所定の軸方向位置に、補助用プリプレグシートＰ３を巻回する。ここでは、２つの補助用プリプレグシートＰ３を巻回している。一方の補助用プリプレグシートＰ３は、上述の第１軸方向プリプレグ素材Ｐ２ａと第２軸方向プリプレグ素材Ｐ２ｂとの連結部分に巻回する。これが元上竿６２の第２嵌合雄部６２ｂを形成することになる。他方の補助用プリプレグシートＰ３は、より穂先側の周面に巻回する。これが元上竿６２の太径部６２ｃを形成する。なお、さらに、第１嵌合雄部６２ａを形成するための補助用プリプレグシートＰ３を上述の軸方向プリプレグシートＰ２の竿元側端部の周面に巻回してもよい。
【０１０８】
その後、必要に応じて、これらの各種プリプレグの周面にポリプロピレン等からなる成型用テープを巻回し、炉内において焼成する。そして、芯材１００を脱芯して周面の成型用テープを剥離し、さらに、周面を研磨加工乃至径調整し、必要な塗装等を施して、元上竿６２を製造する。
【０１０９】
なお、この方法では、周方向プリプレグシートＰ１と軸方向プリプレグシートＰ２とを順次巻回しているが、両者を予め積層させておき、一回的に芯材１００に巻回してもよい。このときも、周方向プリプレグシートＰ１が芯材１００側に位置するようにする。
【０１１０】
このような方法にあっては、一方の補助プリプレグシートＰ３が第２嵌合雄部２ａを形成する。そして、この部分より竿元側は第２軸方向プリプレグ素材Ｐ２ｂにより剛性が低く抑えられた部分として、また小径の領域として構成される。一方、第２嵌合雄部６２ａより穂先側は第１軸方向プリプレグ素材Ｐ２ａにより剛性が高く、また、竿元側ほど太径になるテーパ領域として構成されることになる。さらに、内層として位置することになる周方向プリプレグシートＰ１が元上竿６２の軸方向全体において必要な潰れ強度を担保している。
【０１１１】
こうして製造される元上竿６２では、第２嵌合雄部６２ａより竿元側の領域が、肉薄・小径且つ低剛性であり、釣竿全体の撓りのバランスが損なうことがない。また、２種の異なる引張弾性率の強化繊維を連結して竿体を製造しているが、両者の連結部分での不当な破断なども生じ難くなっている。
【０１１２】
なお、上記元上竿２の製造方法は一例を示すものであり、ここで特定した数値等に製造方法が限定されるものではない。製造するべき元上竿６２の径，必要とされる強度等の条件に沿って、任意に調整変更するべきものである。
【０１１３】
［他の実施形態］
（ａ）さらに、上記の各実施形態において採用した穂先竿５の変形例を示す。
この実施形態における穂先竿も、上記第１実施形態と同様に２本の竿体を連結して一本の竿体としたものである。即ち、図１６に示すように、この穂先竿は、穂先側に位置する中実竿体９６とその竿元側に位置する中空竿体９７との２本の竿体を連結して固定したものである。
【０１１４】
中実竿体９６及び中空竿体９７の構成は、原則として上記第１実施形態と同様のものである。即ち、中実竿体９６は竿元側端部に連結部９８を有し、中空竿体９７は穂先側端部内周が受け部９９となっている。そして、この連結部９８を受け部９９に挿入した上で接着剤によって相互に接着固定されている。
【０１１５】
もっとも、この中実竿体９６の連結部９８は、上記第１実施形態と異なり、竿元側ほど急激に小径化する逆テーパ部Ｘ２のみではなく、その竿元側に連続する延伸部Ｙ２も竿元側ほど小径化するテーパが施されている。逆テーパ部Ｘ２はそのテーパ率は５０／１０００程度に設定されるが、延伸部Ｙ２のテーパはより緩やかなテーパで、１〜１０／１０００程度に設定すれば足りる。その上で、上記第１実施形態と同様に、中実竿体２０の連結部９８以外の部分（本体部）と連結部９８の逆テーパ部Ｘ２との臨界と、延伸部Ｙ２の竿元側端部とがそれぞれ外方向に膨らむ曲面（Ｒ面）となっている。
【０１１６】
さらに、この中実竿体９６の連結部９８においては、竿元側端面から穂先側方向に向かって空間が形成されている。この空間はおよそ連結部９８の逆テーパ部Ｘ２の穂先側付近まで形成されれば足りる。そして、この空間の穂先側は拡径しており、入り口側（竿元側端部）に比較して大きな空間を形成している。
【０１１７】
このような連結部９８に空間を形成する中実竿体９６は、例えば、竿元側端部に空洞を形成した左右一対の半割部材を貼り合わせ、その貼り合わせた半割部材の外周面に、プリプレグシート若しくはプリプレグテープを巻回し、焼成して一体化させて製造することができる。
【０１１８】
一方、中空竿体９７は、上記第１実施形態と同種のものであり、全体として穂先側ほど小径化するテーパが施された先細り筒状部材である。炭素繊維強化樹脂等の素材を焼成して形成されている。穂先側端部の内周が上述の連結部９８を受ける受け部９９となっているが、受け部９９は、上述の連結部９８の逆テーパ部Ｘ２に対応するようにその内径が設定されており、延伸部Ｙ２との接触は予定されない。そして、中空竿体９７と中実竿体９６とは、連結部９８を受け部９９に挿入した上で、専ら逆テーパ部Ｘ２での両者の接着によって連結固定される。なお、上記第１実施形態と同様に、中空竿体９７と中実竿体９８との外周面にはゴム系塗料を塗布してもよい。
【０１１９】
このような構造では、延伸部Ｙ２をテーパ面として中空竿体９７の内周面への接触を可及的に抑え、中実竿体９６と中空竿体９７との連結力は専ら逆テーパ部Ｘ２に於ける接着に委ねる。そして、延伸部Ｙ２の中空竿体９７内での自由度をある程度確保することで、受け部９９若しくは連結部９８へ負荷がかかった際の両者の破損の進行をさらに抑えている。
【０１２０】
（ｂ）さらに、図１７に示すように、中実竿体９６の延伸部Ｙ２は軸方向に径がおよそ変化しないようなものとしても良い。そして、特に、この中実竿体９６の連結部に竿元側端面から空間を形成するに当たっては、延伸部Ｙ２の領域内のみにおいて空間を形成してもよい。
【０１２１】
（ｃ）上記各実施形態で採用する穂先竿では、中実竿体と中空竿体との連結部分の外周面にゴム系塗料を塗布するような場合を例示しているが、両者の境界面に他のプリプレグシートを巻回し焼成して一体化させ、さらに周面塗装を施して外観を整える手法も採用できる。若しくは、プリプレグシートに代えて、エポキシ樹脂等を含浸させた紐体を巻回し、焼成して一体化させるような手法も採用できる。
【０１２２】
（ｄ）さらに、上記各実施形態に採用し得る別の穂先竿８０を図１８に示す。
この穂先竿８０も、上記第１実施形態と同様に２本の竿体を連結して一本の竿体としたものである。即ち、図１８に示すように、この穂先竿８０は、穂先側に位置する中実竿体８１とその竿元側に位置する中空竿体８２との２本の竿体を連結して固定したものである。
【０１２３】
中実竿体８１及び中空竿体８２の構成は、原則として上記第１実施形態と同様のものである。即ち、中実竿体８１は竿元側端部に連結部８３を有し、中空竿体８２は穂先側端部内周が受け部８２となっている。
【０１２４】
連結部８３は、竿元側ほど小径化する逆テーパ部分Ｘ３と、その竿元側に連続する軸方向において径の変化しない延伸部Ｙ３と有する。例えば、逆テーパ部分Ｘ３は１０ｍｍ程度、延伸部Ｙ３は１７ｍｍ程度に設定する。
【０１２５】
一方、中空竿体８２の内周面は、穂先側端部から順に、第１テーパ部分Ｌ、ストレート部分Ｍ、第２テーパ部分Ｎの３つに区分できる。第１テーパ部分Ｌは竿元側ほど小径化する部分であり、上述の逆テーパ部分Ｘ３に合致するように調整される。ストレート部分Ｍは軸方向に内径が変化しない部分である。上述の延伸部Ｙ３の軸方向長さより短く設定されており、例えば、上記延伸部Ｙ３の例に対応させれば１５ｍｍ程度に設定する。第２テーパ部分Ｎは竿元側ほど大径化するテーパ面である。そして、中空竿体８２と中実竿体８１とは、中実竿体８１の逆テーパ部分Ｘ３及び延伸部Ｙ３の周面に塗布される接着剤によって、接着固定されている。従って、この第１テーパ部分Ｌとストレート部分Ｍとが受け部８４となる。
【０１２６】
このような、ストレート部分Ｍ，第２テーパ部分Ｎにより、延伸部Ｙ３の竿元側端部はストレート部分Ｍより竿元側に突出し、延伸部Ｙ３の竿元側端縁と第２テーパ部分Ｎとの間にはクリアランスが発生する。このクリアランスによって、穂先竿８０が大きく撓り、連結部８３と中空竿体８２の穂先側の内周面との接触部分に大きな負荷がかかっても、連結部８３の竿元側端縁は中空竿体８２の内周面に直接接触していないので、この連結部８３の竿元側端縁に応力が集中して、連結部８３の竿元側端縁からの破損が進行し難い。
【０１２７】

BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod in which a plurality of rods are connected in a so-called swinging manner. In particular, the present invention relates to a fishing rod devised so that specific rods can be connected and fixed to each other in both the housed state and the extended state, and fishing can be performed by changing the overall length of the rod.
[0002]
[Prior art]
In a conventional fishing rod, a plurality of cylindrical rods can be sequentially inserted from the tip-side rod into the rod-side rod. When fishing, each chassis is pulled out to the tip side sequentially and fitted and fixed to be used as a single chassis. On the other hand, at the time of storage, the body on the tip side is sequentially stored in the body on the base side to make it compact.
[0003]
In addition, some conventional fishing rods have been devised so that fishing can be performed by changing the overall length of the rod. The fishing rod devised in this way is, for example, a base rod having a fitting female portion on the inner peripheral surface of the tip side end portion, and a central portion in the longitudinal direction while having a first fitting male portion on the outer peripheral surface of the hook side end portion. And an original upper collar having a second fitting male part on the outer peripheral surface (see, for example, Patent Document 1).
[0004]
In this type of fishing rod, when the former rod connected to the tip side of the former rod is pulled out to the tip side (hereinafter referred to as “stretched state”), the fitting female portion is referred to as the first fitting male portion. In a state in which the fitting upper part is inserted and the former upper part is inserted into the former part (hereinafter referred to as “storage state”), the fitting female part can be fitted to the second fitting male part.
[0005]
In this way, the main rod and the upper rod can be fitted and fixed to each other in both the “extended state” and the “retracted state”, and fishing can be performed by changing the entire length of the fishing rod according to the situation. It has become.
[0006]

JP 2000-262189 A (first and second columns, FIGS. 1 and 2)
[0007]
[Problems to be solved by the invention]
In a fishing rod that can change the overall length of the fishing rod as described above, the angler generally uses one hand to move the marine rod with the other hand when converting between the “extended state” and the “storing state”. While gripping the heel side or the vicinity of the reel sheet, the other hand holds the vicinity of the tip of the second fitting male part of the heel of the base and pulls out or stores the heel of the base from the base. For this reason, restrictions arise in the drawer length of the former upper bowl.
[0008]
First, the first constraint is due to the length of the angler's hand.
That is, as shown in FIG. 19, the “drawing length” when the former upper collar 102 is pulled out from the former collar 101 (the tip side of the second fitting male portion 102b of the former upper collar 102 in the stretched state from the vicinity of the reel sheet) It is difficult to set the distance to (see X in FIG. 19) longer than the distance when the angler spreads his hand.
[0009]
However, the fishing rod designed to change the overall length of the fishing rod is a change in the entire length of the fishing rod between the storage state and the extended state, that is, the “drawer length when the upper rod is pulled out from the former rod. "Is set to a large value, and the purpose is to facilitate fishing according to the situation. Therefore, a device that can increase the change in the entire length of the fishing rod between the stored state and the extended state is required.
[0010]
Next, the second constraint is a structural constraint.
That is, the “drawer length” (X in FIG. 19) in this type of fishing rod that can change the length of the fishing rod as a whole is generally defined by It corresponds to the length between the mating male part formed on the peripheral surface on the tip side of the former upper bowl with a larger diameter. This is because, as shown in FIG. 19 described above, it is common that the base end portion of the heel of the heel and the fitting male portion are fitted to the fitting female portion of the tip side of the heel. It is. Such structural constraints greatly reduce the degree of design freedom.
[0011]
Therefore, in order to avoid such a restriction on the “drawer length” and increase the degree of freedom of design, even in the stretched state, all the upper part of the motogami cocoon should not be exposed on the tip side of the fountain. It is conceivable to set a fitting portion with the main fence.
[0012]
However, when such a structure is adopted for the former collar, the area closer to the collar than the fitting male part of the former collar is always located in the former without being exposed to the outside of the former, In the stored state, it is used only for fitting with the base end of the base. Such a region on the heel side of the former upper rod does not produce strength or rigidity of the fishing rod. Rather, the existence of such a region may impair the balance between the flexible bending and bending of the fishing rod as a whole.
[0013]
The subject of this invention is providing the technique which can set the grade of the change of the length freely in providing the fishing rod which can adjust the length of the whole fishing rod.
[0014]
[Means for Solving the Problems]
A certain fishing rod relating to the present invention is a fishing rod formed by sequentially connecting a plurality of rods that are cylindrical bodies, and a marine rod having a fitting female portion on the inner peripheral surface of the tip side end portion, and a tip in the marching rod. A first upper male hook that is connected to the outer side and has a first fitting male part formed on the outer peripheral surface of the heel side, and a second fitting male part on the outer peripheral surface of the tip side, A tip side end is connected to the outer peripheral surface adjacent to the tip side of the second fitting male part of the former upper collar, and includes an auxiliary sleeve that extends to the proximal side so that the former collar and the former upper collar can be accommodated therein. .
[0015]
In the stretched state in which the Motogami cocoon is completely pulled out to the tip of the Motosu, and in the stowed state in which the Motogami cocoon is completely housed inside the Motobu, the Motogami Goto and the Marshal are interconnected. It is possible to fix, and specific modes in each state are as follows.
[0016]
First, in the stretched state, the fitting female portion of the former collar and the first fitting male portion of the former upper collar are fitted together. These fitting portions prevent the former upper collar from coming off from the former collar, and connect and fix the mutual casings. On the other hand, in the housed state, the fitting female portion of the former collar and the second fitting male portion of the former upper collar are fitted together. The mutual housings are connected and fixed.
[0017]
In such an interconversion between the stretched state and the stored state, the angler grasps the vicinity of the reel seat with one hand while grasping the outer peripheral surface of the heel side of the auxiliary sleeve with the other hand. Do. Since the auxiliary sleeve extends from the second fitting male part of the upper rod toward the heel side, the angler can perform the operation without excessively widening the distance between both hands. In addition, the “drawing length” when the upper arm is pulled out of the main arm can be set larger by the axial length of the auxiliary sleeve.
[0018]
Another fishing rod of the present invention is a fishing rod formed by sequentially connecting a plurality of rod-shaped rods, and has a first fitting female portion on the inner peripheral surface in the vicinity of the center in the axial direction. A main rod having a second fitting female portion on the inner peripheral surface of the side end portion, and a fitting male portion formed on the outer peripheral surface of the heel side end portion, which is connected to the front end of the main rod so as to be able to enter and exit. And an auxiliary sleeve that is connected to an outer peripheral surface of the former upper collar and has an end that is connected to the outer edge of the former upper collar so as to accommodate the former collar and the former upper collar.
[0019]
The former upper collar and the former collar have an extended state in which the fitting male part is fitted to the first fitting female part and a storage state in which the fitting male part is fitted to the second fitting female part. . In addition, the auxiliary sleeve accommodates the main rod and the upper collar in the housed state, accommodates the former upper collar in the stretched state, and at the edge of the collar, the end on the tip side of the hammer Covering.
[0020]
In the extended state in which the fitting male part of the former collar is fitted to the first mating female part of the former collar, the fitting portion serves as a stopper against the former collar of the former collar and The body is connected and fixed. In this state, the auxiliary sleeve accommodates a part of the heel of the former and also covers the end of the edge of the heel. The auxiliary sleeve obscures the step between the end side of the edge of the main shaft in the stretched state and the peripheral surface of the upper surface, which can result from a difference in the outer diameter between the main shaft and the upper surface, and the dust enters the gap. To prevent bad appearance.
[0021]
On the other hand, even in the housed state where the second fitting female part of the former collar and the fitting male part of the former upper collar are fitted to each other, the mutual casings are connected and fixed. In this state, the auxiliary sleeve accommodates the former sleeve together with the former upper collar.
[0022]
In such mutual conversion between the stretched state and the stored state, the angler performs the operation by grasping the outer peripheral surface of the auxiliary sleeve with the other hand while grasping the vicinity of the reel seat with one hand. The auxiliary sleeve extends to the heel side on the peripheral surface of the former upper rod, and the angler can perform the operation without excessively widening the distance between both hands. Further, the “drawing length” when the upper arm is pulled out from the main arm can be set to the axial length of any auxiliary sleeve.
[0023]
◎ Another fishing rod of the present invention is a fishing rod formed by sequentially connecting a plurality of rods that are cylindrical bodies, and a main rod having a fitting female portion on the inner peripheral surface of the tip end side, A first fitting male portion formed on the outer peripheral surface of the heel side end portion and connected to the head end side so as to freely enter and exit from the adjacent portion on the outer peripheral surface in the axial direction. The end part on the tip side is connected to the outer peripheral surface adjacent to the tip side of the second fitting male part of the former upper collar and the second fitting male part of the former upper collar, and the former collar and the former upper collar are accommodated therein. And an auxiliary sleeve extending to the base side as possible.
[0024]
The region from the tip side end portion of the former upper collar to the second fitting male portion is thicker and has higher bending rigidity than the region closer to the collar side than the second fitting male portion. The former upper collar and the former collar have an extended state in which the fitting male part is fitted to the first fitting female part and a storage state in which the fitting male part is fitted to the second fitting female part. The auxiliary sleeve accommodates the heel and the upper collar in the housed state, accommodates the former heel in the stretched state, and at the heel side end, Covering.
[0025]
In the relationship with the marshal rod, the first mating male part and the second mating male part are fitted into the marshal in the retracted state and the extended state, respectively. In this case, the region on the heel side from the second fitting male part is always located in the heel without being exposed to the outside of the heel, and in the retracted state, the region of the heel side on the heel side is fitted. This part is used only for the purpose. This region is thinner and lower in bending rigidity than the tip side region, and the balance of bending of the entire fishing rod is not impaired.
[0026]
In addition, the taper is given to the area | region from the edge side edge part of a former upper heel to the 2nd fitting male part, and the area | region of the heel side from the 2nd fitting male part of the former upper edge is the tip. You may set so that it may be a small diameter compared with the area | region from a side edge part to a 2nd fitting male part.
[0027]
When set in this way, in either the extended state or the stored state, the region from the tip side end portion to the second fitting male portion that is exposed to the outside and produces the change or balance of rigidity of the entire fishing rod Becomes a general taper portion. On the other hand, the area on the heel side from the second fitting male part has a smaller diameter than the area from the tip side end part to the second fitting male part, and contributes to the balance of the whole fishing rod as much as possible. It is suppressed.
[0028]
Furthermore, the region on the heel side from the second fitting male portion of the upper collar may be set to have a smaller diameter compared to the region from the tip side end portion to the second fitting male portion. .
[0029]
In this way, by setting the predetermined region to be one step smaller in diameter, it is possible to minimize the contribution of balance to the entire fishing rod in the region closer to the base than the second fitting male part of the upper upper rod.
[0030]
◎ Further, in addition to the above-mentioned main rod and former upper rod, another fishing rod of the present invention includes a middle rod connected to the inner rod so as to be able to enter and exit toward the tip side, and a tip side within the middle rod. It is further provided with a tip ridge that is connected so as to be able to move in and out.
[0031]
This ear cocoon has a solid body having a main body part and a connecting part formed at the base side end part of the main body part, and a receiving part into which the connecting part of the solid steel body is inserted is formed at the tip side end part. And a hollow housing in which the connecting portion is inserted and fixed to the receiving portion. The connecting portion of the solid rod body has a tapered portion having a taper that is reduced in diameter toward the base side and an extending portion that does not change in diameter in the axial direction extending to the base side of the taper portion. The critical part of the main body part of the body and the tapered part of the connecting part and / or the base end part of the extending part is a curved surface that swells outward. Further, the inner surface of the tip side end portion of the receiving portion is a tapered surface that matches the tapered portion.
[0032]
Such a tip of a fishing rod has a predetermined curved surface at a connecting portion of the solid rod inserted into the hollow rod. The whole fishing rod is greatly bent due to the fish being involved in the mechanism, and the solid rod body and the hollow rod body are also greatly bent even at the tip rod, and the contact portion between the connecting portion and the inner peripheral surface of the receiving portion of the hollow rod body Even when a large load is applied, the diameter of the connecting portion changes, and the portion protruding outward is curved, and the breakage of the receiving portion or the connecting portion is difficult to proceed from these portions. .
[0033]
Note that the extending portion of the connecting portion may be tapered so that the diameter gradually decreases toward the base side from the tapered portion. When such a taper is applied, the tip of the fishing rod has a tapered portion as a tapered surface to suppress contact with the peripheral surface of the hollow housing as much as possible. In other words, it is left to the adhesion at the taper portion exclusively. By securing a certain degree of freedom in the hollow housing of the extending portion, the progress of breakage of both when the receiving portion or the connecting portion is loaded is suppressed.
[0034]
Further, in the solid rod body, a space may be formed in the vicinity of the connecting portion from the heel side end surface toward the tip side. Such a space in the vicinity of the connecting portion of the solid casing secures the degree of freedom of the solid casing to some extent and suppresses the progress of breakage of both when the receiving portion or the connecting portion is loaded.
[0035]
In this type of fishing rod tip, the peripheral surface of the connecting portion between the solid rod body and the hollow rod body may be further coated with a rubber-based paint. This rubber-based paint absorbs the subtle misalignment of the connecting surface between the solid housing and the hollow housing, where stress tends to concentrate, in particular, the peripheral surface of the connecting portion of both housings. Reduce the occurrence of cracks.
[0036]
In addition, a reel sheet on which the reel can be detachably mounted may be disposed on the peripheral surface of the auxiliary sleeve.
[0037]
◎ Still another fishing rod of the present invention includes a plurality of slide guides arranged to be slidable in the axial direction on the peripheral surfaces of the middle rod and the tip rod, and a sleeve guide arranged to be slidable on the auxiliary sleeve. And a top cover used when housing each housing.
[0038]
This top cover is formed continuously on the tip base side of the mounting base and the mounting base that comes into contact with the tip end side peripheral surface of the top of the former base in the storage state in which the tip hook and the middle hook are stored in the top hook And a guide protection portion that surrounds and holds the plurality of slide guides, and a holding portion that is provided at the base side end portion of the mounting base portion and holds the sleeve guide.
[0039]
According to this configuration, when the fishing rod is stored, the slide guides are aligned on the tip side of each rod along the axial direction of the fishing rod. In this state, when the mounting base is disposed along the peripheral surface of the distal end portion of the original upper collar, each slide guide is surrounded and held by the guide protector. Further, when the mounting base is disposed on the peripheral surface of the distal end portion of the former upper collar, the sleeve guide is also slid to the tip side, and the holding portion is engaged with the sleeve guide. Thus, the sleeve guide is positioned and held at a predetermined position with respect to the fishing rod.
[0040]
The sleeve guide has a frame having an annular part fitted to the peripheral surface of the auxiliary sleeve and a guide ring attached to the frame, and the holding part has a peripheral surface and an annular part on the tip side of the former upper collar. It is good also as a structure which has an insertion part press-fit between the inner peripheral surfaces.
[0041]
In this case, the sleeve guide is positioned and engaged with the auxiliary sleeve by fitting the annular portion of the frame to the auxiliary sleeve.
[0042]
When the fishing rod is in the stowed state, the sleeve guide is slid to the tip side of the auxiliary sleeve and reaches the tip surface side of the former upper rod. Since the outer diameter of the former upper collar is set smaller than the outer diameter of the auxiliary sleeve, when the sleeve guide is slid to the front end side, A predetermined gap is formed between the peripheral surface of the upper collar. An insertion member is inserted into the gap, whereby the sleeve guide is positioned and fixed and attached to the top cover.
In addition, you may comprise the insertion part of a holding | maintenance part from elastic rubber.
[0043]
Further, in the fishing rod relating to the present invention, another tip rod as described below may be used. The other tip is a solid rod having a main body and a connecting portion formed at the base end of the main portion, and a receiving portion into which the connecting portion of the solid rod is inserted is a tip end. And a hollow housing having a connecting portion inserted into the receiving portion and bonded and fixed thereto.
[0044]
The connecting portion of the solid rod body has a tapered portion having a taper that decreases in diameter toward the base side and an extending portion that does not change in diameter in the axial direction that extends to the base side of the tapered portion. On the other hand, the inner surface on the tip side of the hollow rod body has a first tapered surface that is reduced in diameter toward the heel side that matches the tapered portion formed from the end portion on the tip side, and a continuous stretch on the heel side of the first tapered surface. A straight surface whose diameter does not change in an axial range shorter in the axial direction than the portion, and a second tapered surface whose diameter increases toward the base side continuous with the base side of the straight surface.
[0045]
In such a tip of a fishing rod, the connecting portion of the solid rod inserted into the hollow rod is in contact with the receiving portion as follows. First, the tapered portion of the connecting portion is in contact with the first tapered surface of the receiving portion. The extending portion of the connecting portion is in contact with the straight surface of the receiving portion. And the heel side edge part of the extending | stretching part of a connection part protrudes from the straight surface to the heel side, and does not contact the 2nd taper surface of a receiving part.
[0046]
The whole fishing rod is greatly bent due to the fish being involved in the mechanism, and the solid rod body and the hollow rod body are also greatly bent even at the tip rod, and the contact portion between the connecting portion and the inner peripheral surface of the receiving portion of the hollow rod body Even if a large load is applied, the base end edge of the connecting part is not in direct contact with the receiving part, so stress concentrates on the base end edge of the connecting part, and the base end of the connecting part It is difficult for the receiving part or the connecting part to break from the edge.
[0047]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
[0048]
(The whole structure of the fishing rod)
As shown in FIG. 1, the fishing rod employing the first embodiment of the present invention includes a main rod 1 having a reel seat 6 to which a reel (not shown) can be detachably attached to a peripheral surface, It has Motogami cocoon 2, first middle cocoon 3, second middle cocoon 4 and tip cocoon 5 which are sequentially connected to the tip side in a swing-out manner. These base rods 1 to 5 are tapered cylindrical members formed from a prepreg material in which carbon fiber or glass fiber is impregnated with a synthetic resin. These are connected in a so-called swing-out form, and the upper heel 2 to the tip heel 5 are inserted into and out of the pod on the heel side sequentially from the tip side. Further, an auxiliary sleeve 15 is attached to the former upper collar 2.
[0049]
When these original upper tubs 2 to 5 are pulled out to the tip side, the respective pods are located on the outer peripheral surface of the heel side end of the pod located on the tip side and on the heel side. They are fitted to each other at the tip end side inner peripheral surface, and can be prevented from coming off to the tip side and connected and fixed to each other. In this state, the angler will fish using this fishing rod. On the other hand, when fishing is completed, the rod body is housed in the rod body on the rod side sequentially from the tip rod 5 to make it compact. Furthermore, in particular, the former upper rod 2 and the former rod 1 can be connected and fixed to each other regardless of whether they are in the extended state or the retracted state, as will be described later. You can fish while adjusting the length.
[0050]
Further, the first center collar 3, the second center collar 4, and the head collar 5 have a fixed guide 9 that is arranged on the most tip side and is immovably fixed in the axial direction, and a shaft on the circumferential surface of the collar side. A plurality of slide guides 10 that are movable in the direction and that can be locked at predetermined positions are arranged as necessary. The fixed guide 9 in the tip 5 is a top guide. The slide guide 10 is fitted to the peripheral surface of the housing at a predetermined axial position on the peripheral surface of each housing to be reduced in diameter, and is slidable toward the tip side.
[0051]
Further, a sleeve guide 16 is also arranged on the peripheral surface of the auxiliary sleeve 15. Similarly to the slide guide 10 described above, the sleeve guide 16 is also arranged on the peripheral surface of the auxiliary sleeve 15 so as to be movable in the axial direction and to be locked at a predetermined position. The sliding movement from the refill sleeve 15 to the tip side is also possible.
[0052]
In this embodiment, the number of housings is 5. However, the number of housings is arbitrarily set and is not limited to this.
[0053]
(About Genroku 1 and Motokami 2)
Next, the connection structure of the former fence 1 and the former upper fence 2 will be described in detail. As schematically shown in FIGS. 2 and 3, the base rod 1 and the base rod 2 are cylindrical bodies each having a constant taper taper.
[0054]
A bottom plug 7 is detachably attached to the end portion of the base side of the base 1. The main rod 1 is a cylindrical body in which the upper rod 2 can be accommodated, and a protective metal ring is attached to the outer peripheral edge of the tip side end portion as necessary. Moreover, the inner peripheral surface of the tip side end part is a fitting female part 1a. This fitting female part 1a is a part formed by reducing the diameter as necessary as compared with other parts.
[0055]
On the other hand, the former upper collar 2 has a first fitting male part 2a formed on the outer peripheral surface of the collar side end and a second fitting male part 2b formed on the outer peripheral surface of the tip side. Yes. Each of these parts is integrally formed with the cylindrical part of the upper collar 2 as follows. In other words, the upper collar 2 is formed into a cylindrical shape by firing a prepreg material obtained by impregnating a reinforcing resin such as carbon fiber with a synthetic resin as described above. When manufacturing such a cylindrical body, the auxiliary prepreg material is wound around the outer peripheral surface of the cylindrical body forming prepreg material at a predetermined predetermined place, and these materials are fired as a whole. In addition, it is preferable to use the auxiliary prepreg used in this case in which reinforcing fibers are oriented in the axial direction of the casing.
[0056]
Therefore, the former rod 1 and the former rod 2 of the fishing rod are, as will be described later, an extended state in which the former rod 2 is pulled out toward the tip of the former rod 1 (see FIG. 3 (b)), and the former rod. 2 can be connected and fixed to each other in either of the storage states (see FIG. 3A) in which the 2 is stored in the main fence 1.
[0057]
On the other hand, the auxiliary sleeve 15 is a cylindrical member having a diameter larger than that of the main shaft 1. A predetermined prepreg material may be fired and formed from a hard synthetic resin, a metal, or the like in the same manner as each casing such as the main fence 1. The auxiliary sleeve 15 has a tip side end connected to an outer peripheral surface adjacent to the tip side of the second fitting male portion 2 b of the former upper collar 2, and a second fitting male portion of the former collar 1 and the former upper collar 2. The base side extends from 2b to the base side so as to be housed therein. A known method may be used for fixing the auxiliary sleeve 15 to the former upper collar 2. In this embodiment, an example is shown in which the auxiliary sleeve 15 is fixed to the peripheral surface of the former upper collar 2 by bonding or the like. However, for example, a method may be adopted in which a female screw portion is formed on the circumferential surface of the original upper collar 2 at a predetermined position and the auxiliary sleeve 15 is screwed, so that the auxiliary sleeve 15 can be removed from the upper collar 2.
[0058]
The length of the auxiliary sleeve 15 in the axial direction can be arbitrarily set, but is set to be at least shorter than the length from the tip side end of the main rod 1 to the reel sheet 6. The outer peripheral surface may be provided with unevenness for preventing slipping so that the user can easily grip it, or a grip made of urethane rubber or the like may be arranged.
[0059]
The sleeve guide 16 disposed on the auxiliary sleeve 15 includes a frame 40 constituting a leg and a guide ring 41. The frame 40 has an annular portion 42, and the annular portion 42 is fitted on the outside of the auxiliary sleeve 15 (see FIG. 10).
[0060]
The inner diameter dimension of the annular portion 42 corresponds to the outer diameter dimension of the auxiliary sleeve 15 at a predetermined axial position. By sliding the sleeve guide 16 to a predetermined position on the auxiliary sleeve 15, the sleeve guide 16 is fixed at a predetermined position by the relationship (fitting) between the inner diameter of the annular portion 42 and the outer diameter of the auxiliary sleeve 15. Further, the sleeve guide 16 can be slid toward the tip side. Fixed to a fixed position.

(About the operation of Genroku 2 and Marshal 1)
In the fishing rod constructed as described above, each rod is sequentially pulled out from the tip rod 5 toward the tip, and fishing is performed as one long rod. After the fishing is finished, each rod is sequentially stored in the rod on the rod side from the tip rod 5 to make it compact. Furthermore, in the state (extended state) in which the former upper basket 2 is completely pulled out to the tip side of the former basket 1, and the state (stored state) in which the former upper basket 2 is completely stored in the interior of the former basket 1. The former rod 2 and the former rod 1 can be connected and fixed to each other, and fishing can be performed by adjusting the length of the entire fishing rod. That is, fishing can be performed in both the state where all the five rods are extended and the state where only the four rods are extended. Specific modes in each state are as follows.
[0062]
In the extended state, as shown in FIG. 3 (b), the fitting female portion 1 a of the heel 1 and the first fitting male portion 2 a of the heel 2 are fitted together. On the other hand, in the housed state, as shown in FIG. 3A, the fitting female portion 1a of the main rod 1 and the second fitting male portion 2b of the upper upper rod 2 are fitted to each other. Then, at the time of mutual conversion between the extended state and the stored state, as shown in FIG. 2, the angler grips the vicinity of the reel seat or the like with one hand and the hook of the auxiliary sleeve 15 with the other hand. Grasp the outer peripheral surface of the former side and perform the operation of taking in and out the upper upper collar 2. Since the auxiliary sleeve 15 extends from the second fitting male part 2b of the upper rod 2 toward the rod side, the angler can operate to remove the upper rod 2 without excessively extending the distance between both hands. . It is also possible to set the “drawing length” when the upper arm 2 is pulled out from the main housing 1 to be larger by the axial length of the auxiliary sleeve 15.
[0063]
(About Hote 5)
Next, the structure of the spike basket 5 will be described.
[0064]
As shown in FIG. 4, the tip cage 5 is obtained by connecting a solid rod 92 on the tip side and a hollow rod 91 on the collar side, and fixing them together to form a single rod. In the spike head 5, the above-mentioned fixing guide 9 (top guide) is attached to the tip side end portion (that is, the tip side end portion of the solid rod body 92), and the tip side end portion (that is, A fitting portion 91a for connecting to another casing is formed on the base end of the hollow casing 91). Further, a plurality of slide guides 10 are also mounted at intervals in the axial direction.
[0065]
The solid rod body 92 is a rod-shaped / solid solid body with a taper that decreases in diameter toward the tip side as a whole. For example, it is formed by pressurizing and heating a carbon fiber reinforced resin in which carbon fibers are aligned in the axial direction and impregnated with a thermosetting resin. And as shown in FIG. 5, the connection part 93 is formed in the edge part by the side of this collar body 92 smaller diameter than another part. The connecting portion 93 has a two-stage structure including a reverse taper portion X1 whose diameter is rapidly reduced toward the base side and an extending portion Y1 which is continuously formed on the base side and does not change in diameter in the axial direction ( (See FIG. 6). For example, in one example, the maximum outer diameter of the solid casing 92 is about 2.10 mm. And the taper rate of the reverse taper part X1 is set to about 50/1000. The length in the axial direction of the reverse tapered portion X1 can be arbitrarily set, but is preferably about 10 mm. The stretched portion Y1 is a portion where there is no change in the diameter in the axial direction or almost no change in the diameter is recognized. The outer diameter of the stretched portion Y1 is about 1.55 to 1.58 mm, and its axial length is about 10 mm or more (for example, 15 mm) as in the case of the reverse tapered portion X described above. Good.
[0066]
As shown in FIG. 6, in this connection part 93, critical P1 of the part (body part) other than the connection part 93 of the solid housing 92 and the reverse taper part X1 of the connection part 93, and the base of the extending part Y1 Each side end P2 is a curved surface (R surface) that swells outward. It is sufficient that the curved surface is formed by polishing after the connection portion 93 is formed. In addition, although curved surface is given in any of P1 and P2 here, you may curved only any one.
[0067]
On the other hand, the hollow casing 91 is a tapered tubular member having a taper that decreases in diameter toward the tip side as a whole. It is formed by firing a material such as carbon fiber reinforced resin. The inner circumference of the end portion on the tip side is a receiving portion 94 that receives the connecting portion 93 described above. The receiving portion 94 has a two-step taper structure with an inner diameter set so as to correspond to the reverse tapered portion X1 and the extending portion Y1 of the connecting portion 93 described above. The receiving portion 94 is formed by reamer processing or the like, and its inner diameter is set to about 1.57 to 1.60 mm, slightly larger than the outer diameter of about 1.55 to 1.58 mm of the extending portion Y1. This is because the adhesive is interposed in the gap.
[0068]
The solid casing 92 and the hollow casing 91 are bonded and fixed by an adhesive after being inserted into the receiving portion 94 from the tip side. Then, as shown in FIG. 5, rubber-based paint 95 is applied to the peripheral surfaces of both the casings within a certain range in the axial direction from the boundary surface portion between the solid casing 92 and the hollow casing 91. The After the application of the rubber-based paint 95, a peripheral surface coating is further applied to the entire peripheral surface of the tip rod 5 so that the connecting portion between the solid rod body 92 and the hollow rod body 91 cannot be recognized from the outside. Good.
[0069]
As described above, such a spike basket 5 has a curved surface at a connecting portion 93 of the solid casing 92 inserted into the hollow casing 91. The whole fishing rod is greatly bent due to the fish being involved in the mechanism, and the solid rod body 92 and the hollow rod body 91 are also greatly bent in the tip rod 5, and the inside of the connecting portion 93 and the receiving portion 94 of the hollow rod body 91 is Even if a large load is applied to the contact portion with the peripheral surface, the diameter of the connecting portion 93 is changed, and the portion protruding outward is curved, and the receiving portion 94 or the connecting portion 93 is formed from these portions. It is difficult for damage to progress.
[0070]
In addition, in this embodiment, although such a special spike tip 5 is used, it is also possible to use other common tip tips 5.
[0071]
(About the top cover 20)

The top cover 20 is for holding the rod body and various fishing line guides (slide guides 10 and the like) constituting the fishing rod in a substantially positioned state, and preventing damage to the fishing line guide and the like during transportation.
[0072]
The top cover 20 includes a mounting base portion 21, a guide protection portion 22, and a holding portion 23. The mounting base portion 21 and the guide protection portion 22 are integrally formed from a synthetic resin such as polycarbonate.
[0073]
When the top cover 20 is mounted on a fishing rod, the mounting base 21 is disposed so as to come into contact with the peripheral surface on the tip side of the former upper rod 2 in which each rod is stored. The mounting base 21 is formed in a straight plate shape, and this portion is arranged along the axial direction along the peripheral surface of the distal end portion of the upper collar 2. Further, the inner surface 24 of the mounting base 21 is formed as a curved surface. The radius of curvature of the inner surface 24 corresponds to the outer diameter of the tip of the fishing rod. Therefore, the mounting base 21 comes into contact with the peripheral surface of the original upper collar 2 in a stable state.
[0074]
As shown in FIG. 7, the guide protection part 22 is formed in an elongated cylindrical shape. The guide protector 22 surrounds and protects each fishing line guide (the slide guide 10 and the fixed guide 9) in a state in which the mounting base 21 is attached to the peripheral surface of the distal end of the former upper rod 2.
[0075]
The guide protector 22 includes a guide support member 25. The guide support member 25 is formed in an elongated rod shape (needle shape). The guide support member 25 is fixed to the bottom surface of the guide protector 22 in a so-called cantilever shape, and extends along the longitudinal direction of the guide protector 22.
[0076]
The guide support member 25 is made of, for example, resin or a bendable metal wire. The guide support members 25 are inserted into the respective fishing line guides. When the guide support members 25 are inserted, the respective fishing line guides are held in a substantially positioned state. A small hole 26 is provided at the tip of the guide support member 25, and it can be used as a so-called threading when the fishing line is inserted into each fishing line guide.
[0077]
The mounting base 21 further has a fixing band 27. The fixed band 27 is made of rubber, for example, and is formed in a thin band shape. The fixing band 27 has a base end portion fixed to the mounting base portion 21, and a through hole 30 is provided at the tip end portion. On the other hand, a protrusion 29 protrudes from the outer surface 28 of the mounting base 21.
[0078]
The fixing band 27 is wound around the mounting base portion 21 along the peripheral surface of the tip of the fishing rod, and the protrusion 29 is fitted into the through hole 30 of the fixing band 27. Thereby, the mounting base 21 is fastened to the fishing rod and securely fixed.
[0079]
The holding unit 23 is made of rubber, for example. But the material which comprises the holding | maintenance part 23 is not limited to rubber | gum, You may be comprised with resin etc. However, it is preferable that the holding part 23 is comprised with the material rich in elasticity, such as rubber | gum. The holding portion 23 is formed in an elongated plate shape as a whole, and includes a base portion 31 and an insertion portion 32 (insertion member).
[0080]
The base 31 is disposed along the inner surface 24 of the mounting base 21. The base 31 is fixed to the mounting base 21 with, for example, an adhesive or a double-sided tape.
[0081]
In this embodiment, the insertion portion 32 is formed integrally with the base portion 31, and extends in the longitudinal direction of the mounting base portion 21 continuously to the base portion 31. The thickness d of the distal end portion of the insertion portion 32 is set to a predetermined size, and can be appropriately set in the range of 1.5 mm to 6.0 mm according to the specifications of the fishing rod.
[0082]
The insertion portion 32 is formed in a so-called wedge shape. Specifically, the lower surface 33 of the insertion portion 32 is inclined with respect to the upper surface 34, whereby the thickness dimension of the insertion portion 32 is set to gradually increase from the distal end portion toward the base portion 31 side. ing. In addition, the maximum thickness dimension of the insertion part 32 may be set in the range of 3 mm-8 mm.
[0083]
In the top cover 20, the insertion portion 32 is formed integrally with the base portion 31, but the insertion portion 32 may be configured as a separate member and connected to the base portion 31. In that case, it is preferable that the insertion part 32 is comprised with material rich in elasticity, such as rubber | gum.
[0084]
(How to attach the top cover 20)
Next, a procedure for mounting the top cover 20 on the upper rod 2 in the housed state in which the rods of the fishing rod of the present invention are housed will be described.
[0085]
As shown in FIG. 10, the user who finished fishing slides the slide guides 10 arranged on the peripheral surfaces of the tip rod 5, the second center rod 4, and the first center rod 3 sequentially toward the tip side. Thus, the body from the tip side of the body to the former upper basket 2 is stored in the forward dimension basket 1. Then, the user stores the tip 5 or the like in the guide protector 22 while bringing the mounting base 21 of the top cover 20 into contact with the tip side peripheral surface of the former upper 2. Further, the user inserts each fishing line guide (fixed guide 9 and slide guide 10) through the guide support member 25.
Further, the user slides the sleeve guide 16 on the auxiliary sleeve 15 toward the tip, and guides the sleeve guide 16 to the peripheral surface of the former upper collar 2. A predetermined gap is formed between the inner peripheral surface of the annular portion 52 of the sleeve guide 16 and the outer peripheral surface of the former upper collar 2 due to the difference in diameter. And the holding | maintenance part 23 engages in this clearance gap. That is, the sleeve guide 16 is positioned and held by the holding portion 23.
[0086]
[Second Embodiment]
A second embodiment of the present invention will be described with reference to FIG.
The general structure of the entire fishing rod is the same as that of the first embodiment, and the tapered rod 51 and the upper rod 52 can be connected and fixed to each other in either the extended state or the retracted state. .
[0087]
The reel sheet 6 is disposed on the peripheral surface of the base 51 as in the first embodiment. Further, a butt plug 7 is detachably attached to the heel side end portion, and a stopper ring 53 (on the second fitting female portion) is provided inside the heel 51 adjacent to the tip side of the bottom plug 7. Corresponding) is arranged. The stopper ring 53 is a cylindrical member penetrating in the axial direction, and a plurality of protrusions protruding radially inward on the inner peripheral surface extend in the axial direction at intervals in the circumferential direction. The stopper ring 53 is inserted from the base side end of the base rod 51 and is fixed by, for example, an adhesive. It may be removable if necessary. Then, a fitting male portion 52a of a former upper collar 52, which will be described later, is inserted and fitted into this protrusion from the tip side (see FIG. 11 (b)).
[0088]
Further, the inner peripheral surface near the center in the axial direction of the base rod 1 is also a portion into which a fitting male portion 52a of the below-described original upper rod 52 is fitted, and is a first fitting female portion 51a (FIG. 11). (See (a)). The first fitting female portion 21a may have a smaller inner diameter than other portions. However, depending on the relationship between the taper of the main rod 51 and the outer diameter of the fitting male portion of the former upper rib 52 described later, You may make it fit on the internal peripheral surface of the predetermined | prescribed axial direction position of the collar 51. FIG. The axial distance between the first fitting female part 51a and the stopper ring 53 corresponds to the “drawing length”. A suitable “drawer length” is about 500 to 600 mm.
[0089]
The former upper collar 52 is also a cylindrical body with a tapered taper similar to the first embodiment. A fitting male part 52a having a diameter larger than that of the other part is set at the end on the heel side. As already described, the fitting male portion 52a can be fitted to a predetermined portion of the main shaft 51.
[0090]
The auxiliary sleeve 15 is also arranged on the peripheral surface of the original upper collar 52. The auxiliary sleeve 15 is a cylindrical member having a diameter larger than that of the main shaft 21. Similar to the first embodiment, the predetermined prepreg material may be formed by firing or may be formed from a hard synthetic resin.
[0091]
The mounting position of the auxiliary sleeve 15 is as follows.
In the extended state (FIG. 11A) in which the fitting male portion 52 a of the upper collar 52 is fitted to the first fitting 51 a of the hammer 51, the collar-side end portion of the auxiliary sleeve 15 is the tip of the hammer 51. The tip side end portion of the auxiliary sleeve 15 is connected to the outer peripheral surface of the upper collar 52 at a position that covers the side end portion. The length of the auxiliary sleeve 15 in the axial direction needs to be set shorter than the length from the tip side end of the base rod 51 to the reel sheet 6. As a result, the axial length of the auxiliary sleeve 15 corresponds to the “drawing length” described above.
[0092]
Even in the fishing rod configured as described above, the upper rod 52 and the main rod 51 can be connected and fixed to each other in either the extended state or the stored state, and fishing can be performed by adjusting the length of the entire fishing rod. . In such an interconversion between the extended state and the stored state, the angler holds the base of the auxiliary sleeve 15 with the other hand while gripping the vicinity of the reel seat or the like with one hand, as in the first embodiment. The side outer peripheral surface can be gripped, and the operation of putting in and out of the upper collar 52 can be performed.
[0093]
In particular, in the extended state as shown in FIG. 11A, the auxiliary sleeve 15 accommodates a part of the upper collar 52 inside and also covers the end part on the tip side of the former collar 51. Then, the auxiliary sleeve 15 covers the step between the end side end of the base rod 51 and the peripheral surface of the base top rod 52 in the stretched state, which may be caused by a difference in outer diameter between the base rod 51 and the base upper rod 52, Suppresses the intrusion of garbage into the gap and prevents bad appearance. Further, the “drawing length” when the former upper collar 52 is pulled out from the former collar 51 can be set to an arbitrary axial length of the auxiliary sleeve 15. That is, the degree of freedom in design related to “drawer length” is improved.
[0094]
[Third Embodiment]
Furthermore, FIG. 12 schematically shows the third embodiment as a modification of the second embodiment.
The connecting structure of the former rod 51 and the former upper rod 52 in this fishing rod is the same as that of the second embodiment. That is, the base rod 51 is provided with a stopper ring (not shown) at the base end portion, and the inner peripheral surface near the center in the axial direction is the first fitting female portion 51a. On the other hand, the former upper collar 52 has a fitting male portion 52a at the edge of the collar side. The auxiliary sleeve 15 is connected to the peripheral surface of the upper collar 52 at a position as described in the second embodiment.
[0095]
In this fishing rod, the reel sheet 6 is disposed on the peripheral surface of the auxiliary sleeve 15. It is sufficient that the reel sheet 6 is mounted with another known member. For example, the reel sheet 6 is wound with a wound yarn or the like to perform resin coating or the like. Alternatively, the pipe-shaped reel sheet 6 may be disposed on the peripheral surface of the auxiliary sleeve 15 and integrally molded.
[0096]
When the reel sheet 6 is arranged on the auxiliary sleeve 15 in this way, as shown in FIG. 12, the length from the reel sheet 6 to the rod side end of the fishing rod is relatively changed due to the state change between the stretched state and the stored state. Changes. By changing the length from the reel seat 6 to the base end of the fishing rod in accordance with the situation of the fishing operation, the angler can perform the fishing operation at the desired reel seat 6 position. For example, as an extended state, it is possible to perform a fishing operation while sandwiching the main rod 51 on the side.
[0097]
[Fourth Embodiment]
Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings.
(Structure of fishing rod)
The basic structure of a fishing rod adopting the fourth embodiment of the present invention is the same as that of the first embodiment. The former fence 61 and the former upper fence 62 have the following structures.
[0098]
As shown in FIGS. 13 and 14, the main rod 61 is a cylindrical body having a certain taper taper. A reel sheet 6 for attaching a reel is mounted on the peripheral surface of the base side of the base rod 61, and an end plug 7 is attached to the end portion of the base side so as to be detachable. This is the same as in the first embodiment. A fitting ring 71 is attached to the outer peripheral edge of the tip side end. The fitting ring 71 is fitted to the heel side end portion of the auxiliary sleeve 15 in the extended state of the upper collar 62, and has a rattling action (see FIG. 14). On the other hand, a thread groove is formed on the inner peripheral surface of the heel side end of the heel 61, and the bottom plug 7 is screwed thereto. The bottom plug 7 has a fitting female portion that accommodates the inner end of the upper collar 62 and can be fitted therein (see FIG. 13).
[0099]
The original upper collar 62 is also a necessary cylindrical body with a tapered taper. It has the 1st fitting male part 62a formed in the diameter larger than the part adjacent to the collar part edge part outer peripheral surface. Further, the second fitting male part 62b is formed in a one-stage thicker diameter than the part adjacent to the outer peripheral surface on the tip side, and further, the large-diameter part one step thicker than the part adjacent to the outer peripheral surface on the tip side. 62c is formed. Each of these portions is formed of a predetermined prepreg material integrally with the cylindrical portion of the upper collar 62 as will be described in detail later. The first fitting male part 62a is in the fitting female part of the bottom plug 7 of the above-mentioned base rod 61 in the housed state, and the second fitting male part 62b is on the inner peripheral surface of the tip end side of the base rod 61 in the extended state. This is the part to be fitted (see FIGS. 13 and 14).
[0100]
Specifically, the upper collar 62 is a highly rigid tapered tubular body from the tip end to the second fitting male part 62b, and the area on the collar side from the second fitting male part 62b is It is one step lower rigidity and smaller diameter than the tip side. The region on the heel side of the second fitting male portion 62b may be a portion where the diameter does not change in the axial direction.
[0101]
The auxiliary sleeve 15 is a cylindrical member having a diameter larger than that of the main rod 61, as in the first embodiment. A predetermined prepreg material may be fired and formed from a hard synthetic resin or a metal material in the same manner as each of the casings such as the main rod 61. The auxiliary sleeve 15 has a tip end side end connected to and fixed to the upper collar 62 at a large diameter portion 62 c formed on the outer peripheral surface adjacent to the tip of the second fitting male part 62 b of the former collar 62. The base rod 61 and the upper base rod 62 extend to the base side so as to be housed therein. A method of fixing the auxiliary sleeve 15 to the upper collar 62 is sufficient if a known method is used. For example, a method such as bonding or screwing may be used. This is also the same as in the first embodiment.
[0102]
(Manufacturing method of the former bowl 62)
Next, the manufacturing method of the above-mentioned former upper cage 62 will be specifically described.
As shown in FIG. 15A, first, a release material necessary for the core material 100 is applied, and the circumferential prepreg sheet P <b> 1 is wound around the peripheral surface of the core material 100. The circumferential prepreg sheet P1 is formed by processing a prepreg material in which carbon fibers and glass fibers are aligned and impregnated with an epoxy resin or the like so that the reinforcing fibers are oriented in the circumferential direction of the core material 100. Is. The circumferential prepreg sheet P1 is set to have a winding length of 1 ply on the tip side and the heel side. In the case where the core material 100 is given a certain taper, the length of the side on the tip side and the side on the heel side are different by the taper. In addition, although the case where the circumferential direction prepreg sheet P1 is used is illustrated here, a prepreg material processed into a tape may be used. In this case, the reinforcing fibers are oriented in the longitudinal direction of the tape. Then, the tape-shaped prepreg material is spirally wound around the core material 100 without a gap.
[0103]
Next, as shown in FIG. 15B, the axial prepreg sheet P2 is wound. The axial prepreg sheet P2 is obtained by bonding and connecting two kinds of prepreg sheets. That is, the axial prepreg sheet P2 includes a first axial prepreg material P2a obtained by impregnating a synthetic resin into a high elastic modulus reinforcing fiber arranged on the tip side, and a low elastic modulus reinforcing fiber arranged on the heel side. And a second axial prepreg material P2b impregnated with a synthetic resin.
[0104]
The first axial prepreg material P2a uses carbon fiber as the reinforcing fiber and its tensile elastic modulus is 40 t / mm. 2 And the carbon fibers are aligned in the axial direction of the core material 100 and oriented. The shape is a substantially trapezoidal shape with the tip side as the short side and the heel side as the long side. Specifically, the short side of the tip side has a winding length of 3 plies, and the long side of the collar side has a winding length of 4 plies. However, in this embodiment, since the connecting portion with the second axial prepreg material P2b is skewed as described later, a part of the long side portion is cut obliquely. As the first axial prepreg material P2a, a substantially trapezoidal shape may be used without forming such an oblique cutout. The height of the substantially trapezoidal shape of the first axial prepreg material P2a (corresponding to the axial length) corresponds to the length from the tip end of the former upper collar 62 to the second fitting male part 62b. To do.
[0105]
The second axial prepreg material P2b uses carbon fiber as the reinforcing fiber and has a tensile modulus of 20 t / mm. 2 And the carbon fibers are aligned in the axial direction of the core material 100 and oriented. Its shape is a substantially rectangular shape, which basically has the same side on both the tip side and the heel side. Specifically, according to the taper of the core material 100, the short side on the tip side is set to have a winding length corresponding to 2 plies and the long side on the heel side also has a winding length corresponding to 2 plies. Does not match. However, in this embodiment, since the connecting portion with the first axial prepreg material P2a is skewed, a part of the side on the tip side protrudes obliquely toward the tip side (the first axial prepreg material). Equivalent to the notch portion of P2a). When the first axial prepreg material P2a is a substantially trapezoidal shape without forming such an oblique notch, the second axial prepreg material P2b is also substantially rectangular. It becomes.
[0106]
Such two kinds of axial prepreg materials are bonded and connected at an oblique portion, and one axial prepreg sheet P2 is wound around the outer periphery of the circumferential prepreg sheet P1. When both are connected, the winding start sides are aligned (the lower side in FIG. 15B) and connected.
[0107]
Subsequently, as shown in FIG. 15C, the auxiliary prepreg sheet P3 is wound at a predetermined axial position on the outer periphery of the axial prepreg sheet P2. Here, two auxiliary prepreg sheets P3 are wound. One auxiliary prepreg sheet P3 is wound around a connecting portion between the first axial prepreg material P2a and the second axial prepreg material P2b. This forms the 2nd fitting male part 62b of the former upper collar 62. FIG. The other auxiliary prepreg sheet P3 is wound around the peripheral surface on the tip side. This forms the large-diameter portion 62c of the upper collar 62. Furthermore, an auxiliary prepreg sheet P3 for forming the first fitting male part 62a may be wound around the peripheral surface of the heel side end of the axial prepreg sheet P2.
[0108]
Thereafter, if necessary, a molding tape made of polypropylene or the like is wound around the peripheral surfaces of these various prepregs and fired in a furnace. Then, the core material 100 is decentered, the molding tape on the peripheral surface is peeled off, the peripheral surface is polished or adjusted in diameter, and necessary coating or the like is applied to manufacture the original collar 62.
[0109]
In this method, the circumferential prepreg sheet P1 and the axial prepreg sheet P2 are wound sequentially, but may be laminated in advance and wound around the core material 100 once. Also at this time, the circumferential prepreg sheet P1 is positioned on the core member 100 side.
[0110]
In such a method, one auxiliary prepreg sheet P3 forms the second fitting male part 2a. The base side from this portion is configured as a portion whose rigidity is suppressed to a low level by the second axial prepreg material P2b and as a small-diameter region. On the other hand, the tip side of the second fitting male part 62a is configured as a tapered region having higher rigidity due to the first axial prepreg material P2a and having a diameter that is larger toward the base side. Furthermore, the circumferential prepreg sheet P <b> 1 to be positioned as the inner layer ensures the necessary crushing strength in the entire axial direction of the upper collar 62.
[0111]
In the upper rod 62 manufactured in this manner, the region closer to the rod than the second fitting male portion 62a is thin, small in diameter, and low in rigidity, so that the balance of bending of the entire fishing rod is not impaired. In addition, the casing is manufactured by connecting two types of reinforcing fibers having different tensile elastic moduli, but it is difficult to cause undue breakage or the like at the connecting portion between the two.
[0112]
In addition, the manufacturing method of the said former bowl 2 shows an example, and a manufacturing method is not limited to the numerical value specified here. It should be arbitrarily adjusted and changed in accordance with conditions such as the diameter of the original collar 62 to be manufactured and the required strength.
[0113]
[Other Embodiments]
(A) Furthermore, the modified example of the spike basket 5 employ | adopted in said each embodiment is shown.
In the same manner as in the first embodiment, the tip rod in this embodiment is also formed by connecting two rods to form one rod. That is, as shown in FIG. 16, the tip rod is obtained by connecting and fixing two rod bodies, a solid rod body 96 located on the tip side and a hollow rod body 97 located on the hook side. It is.
[0114]
The structures of the solid casing 96 and the hollow casing 97 are basically the same as those in the first embodiment. That is, the solid rod body 96 has a connecting portion 98 at the base side end portion, and the hollow rod body 97 has a receiving end 99 at the inner periphery of the tip side end portion. And after inserting this connection part 98 in the receiving part 99, it mutually adheres and is fixed by the adhesive agent.
[0115]
However, unlike the first embodiment, the connecting portion 98 of the solid housing 96 is not limited to the reverse taper portion X2 whose diameter is rapidly reduced toward the heel side, but also an extended portion Y2 continuous to the heel side. A taper that reduces the diameter toward the base side is applied. The taper rate of the reverse taper portion X2 is set to about 50/1000, but the taper of the extending portion Y2 is a gentler taper and it is sufficient to set it to about 1 to 10/1000. In addition, as in the first embodiment, the criticality between the portion (main body portion) other than the connecting portion 98 of the solid casing 20 and the reverse tapered portion X2 of the connecting portion 98, and the base side of the extending portion Y2 Each of the end portions is a curved surface (R surface) that swells outward.
[0116]
Furthermore, in the connection part 98 of this solid rod body 96, the space is formed toward the tip side direction from the collar side end surface. It is sufficient that this space is formed to the vicinity of the tip side of the reverse tapered portion X2 of the connecting portion 98. And the tip side of this space is expanded in diameter, and a large space is formed as compared with the entrance side (end side end portion).
[0117]
The solid casing 96 that forms a space in such a connecting portion 98 is formed by, for example, bonding a pair of left and right half members having a cavity at the base side end and bonding the outer peripheral surface of the bonded half members. In addition, a prepreg sheet or a prepreg tape can be wound, fired and integrated.
[0118]
On the other hand, the hollow housing 97 is the same type as that of the first embodiment, and is a tapered cylindrical member having a taper that decreases in diameter toward the tip side as a whole. It is formed by firing a material such as carbon fiber reinforced resin. The inner periphery of the tip side end portion is a receiving portion 99 that receives the above-described connecting portion 98, and the receiving portion 99 has an inner diameter set so as to correspond to the reverse tapered portion X2 of the above-described connecting portion 98. Therefore, contact with the stretched portion Y2 is not planned. The hollow casing 97 and the solid casing 96 are connected and fixed by inserting the connecting portion 98 into the receiving portion 99 and then bonding them together at the reverse tapered portion X2. As in the first embodiment, rubber-based paint may be applied to the outer peripheral surfaces of the hollow casing 97 and the solid casing 98.
[0119]
In such a structure, the extending portion Y2 is used as a tapered surface to suppress contact with the inner peripheral surface of the hollow housing 97 as much as possible, and the coupling force between the solid housing 96 and the hollow housing 97 is exclusively the reverse tapered portion. Leave to X2 bonding. Further, by securing a certain degree of freedom in the hollow casing 97 of the extending portion Y2, the progress of both breakage when the receiving portion 99 or the connecting portion 98 is loaded is further suppressed.
[0120]
(B) Further, as shown in FIG. 17, the extending portion Y <b> 2 of the solid casing 96 may have a diameter that does not change in the axial direction. In particular, when forming a space in the connecting portion of the solid rod body 96 from the end surface on the heel side, a space may be formed only in the region of the extending portion Y2.
[0121]
(C) In the tip rod employed in each of the above embodiments, a case where a rubber-based paint is applied to the outer peripheral surface of the connection portion between the solid rod body and the hollow rod body is exemplified, but the boundary surface between the two In addition, another prepreg sheet may be wound and fired to be integrated, and a peripheral surface coating may be applied to adjust the appearance. Alternatively, instead of the prepreg sheet, a method in which a string body impregnated with an epoxy resin or the like is wound, fired and integrated can be employed.
[0122]
(D) Further, another tip cocoon 80 that can be adopted in each of the above embodiments is shown in FIG.
As with the first embodiment, the tip rod 80 is also formed by connecting two rods into a single rod. That is, as shown in FIG. 18, the tip rod 80 is fixed by connecting two rods, a solid rod 81 located on the tip side and a hollow rod 82 located on the hook side. Is.
[0123]
The structures of the solid casing 81 and the hollow casing 82 are basically the same as those in the first embodiment. That is, the solid casing 81 has a connecting portion 83 at the base end, and the hollow casing 82 has a receiving end 82 at the inner periphery of the tip end.
[0124]
The connecting portion 83 includes a reverse taper portion X3 having a smaller diameter on the heel side and an extending portion Y3 whose diameter does not change in the axial direction continuous to the heel side. For example, the reverse taper portion X3 is set to about 10 mm, and the extending portion Y3 is set to about 17 mm.
[0125]
On the other hand, the inner peripheral surface of the hollow housing 82 can be divided into three parts, a first taper portion L, a straight portion M, and a second taper portion N, in order from the tip side end. The first taper portion L is a portion whose diameter decreases toward the base side, and is adjusted to match the above-described reverse taper portion X3. The straight portion M is a portion where the inner diameter does not change in the axial direction. The length is set to be shorter than the length in the axial direction of the stretched portion Y3 described above. For example, the length is set to about 15 mm if it corresponds to the example of the stretched portion Y3. The second taper portion N is a tapered surface that increases in diameter toward the base side. The hollow housing 82 and the solid housing 81 are bonded and fixed by an adhesive applied to the peripheral surfaces of the reverse tapered portion X3 and the extending portion Y3 of the solid housing 81. Accordingly, the first tapered portion L and the straight portion M serve as the receiving portion 84.
[0126]
Due to the straight portion M and the second taper portion N, the heel-side end portion of the extending portion Y3 protrudes from the straight portion M toward the heel-side, and the heel-side end edge of the extending portion Y3 and the second taper portion N Clearance occurs between the two. Even if a large load is applied to the contact portion between the connecting portion 83 and the inner peripheral surface on the tip side of the hollow housing 82 due to this clearance, the end edge of the connecting portion 83 is hollow. Since it is not in direct contact with the inner peripheral surface of the housing 82, stress concentrates on the heel side edge of the connecting portion 83, and damage from the heel side edge of the connecting portion 83 does not easily proceed.
[0127]
