【０００１】
【発明の属する技術分野】
本発明は、釣竿に関し、特に、例えばリールの取付脚部を締め付けるナット部材等の回動部材に係合し、このような回動部材で移動される摺動部材を、竿管に対して回転不能とする回り止め機構を備えた釣竿およびリール脚固定装置に関する。
【０００２】
【従来の技術】
一般に、釣竿のリール脚固定装置は、魚釣用リールの取付脚部が載置されるシート本体と、リールの取付脚部を受け入れる開口を有し且つシート本体の軸方向に沿って互いに前後に対向して配置される一対のフードとを備えており、少なくとも一方のフードをシート本体の軸方向に沿って移動させ、これらの一対のフード間にリールの取付脚部を挟持させることにより、リールを釣竿に装着する。
【０００３】
このようなリール脚固定装置には、ナット部材の締め付け動作によってフードを移動および固定するナット式のもの、あるいは、レバーの起伏操作によってフードを移動および固定するレバー式のものなど、従来から様々なタイプのものが知られている。また、シート本体に関しても、リング状のものや板状のものなど、各種の形状のものが知られている。
【０００４】
特公昭５７−２７２４５号公報には、ナット式のリール脚固定装置が記載されている。このリール脚固定装置は、釣竿に固定される筒状本体と、リールの取付脚部の一方側を係止するフードを設けた固定スリーブと、リールの取付脚部の他方側を係止するフードを設けた摺動スリーブとを備える。この摺動スリーブのフードを固定スリーブのフードに対向させた状態で案内する回り止め機構として、摺動スリーブの内周面から突出する突起と、筒状本体の外周面に延設され、この突起を軸方向に平行に案内するキー溝とを備える。更に、この筒状本体の外周面には、摺動スリーブを移動させる螺環を螺合させてある。摺動スリーブの突起をこのキー溝に嵌め込み、螺環を回動すると、摺動スリーブは突起とキー溝とで回り止めされることにより、各フードを正確に整合させた状態を維持しつつ、軸方向に平行に自由に前後動することができる。
【０００５】
【発明が解決しようとする課題】
しかし、キー溝に摺動スリーブの突起を嵌合させることは、このキー溝の溝幅が狭く、また、突起が摺動スリーブの内部に配置されているため、その位置合わせに面倒な操作を必要とする。キー溝に突起が正確に嵌め込まれてない状態で、螺環を回動すると、回り止め機構のキー溝あるいは突起が損傷し、更に、螺環あるいはこの螺環を螺合する筒状本体のネジも損傷し、作動不良の原因となる。
本発明は、このような事情に着目してなされたもので、このような回り止め機構あるいはネジ部の作動不良を防止可能で、円滑に操作することのできる操作性に優れた釣竿およびリール脚固定装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成する本発明の釣竿は、竿管の周部に設けたネジ部に螺合し、竿管に沿って移動可能な回動部材と、この回動部材に係合し、竿管の周部に摺動自在に装着された摺動部材と、この摺動部材を竿管に対して回転不能とする回り止め機構と、を備え、この回り止め機構は、竿管と摺動部材との一方に設けられかつ一端を軸方向に開口させた回り止め溝と、竿管と摺動部材との他方に設けられかつこの回り止め溝内に軸方向一端の開口から挿入される回り止め突起とを有し、この回り止め突起と回り止め溝とが係合したときに、竿管に対して回転することなく軸方向に沿ってのみ移動可能とし、この回り止め突起と回り止め溝とが係合解除したときに、竿管に対する回転および軸方向移動を可能とする釣竿であって、前記回動部材を介して摺動部材を移動させたときに、前記回り止め突起を回り止め溝内に案内する案内部を、前記回り止め溝の一端に近接させて設けたことを特徴とする。
【０００７】
また、上記目的を達成する本発明のリール脚固定装置は、釣竿に設けられ、魚釣用リールの取付脚部が載置されるシート本体と、このシート本体に、シート本体の軸方向に沿って互いに対向させて設けられ、それぞれがリールの取付脚部を受け入れる開口を有し、かつ、少なくとも一方がシート本体に対して移動可能な一対のフードと、このシート本体の周部に設けられたネジ部に螺合され、移動可能な移動フードに係合してこの移動フードをシート本体に沿って移動するナット部材と、この移動フードをシート本体に対して回転不能とする回り止め機構と、を備え、この回り止め機構は、シート本体と移動フードとの一方に設けられかつ一端を軸方向に開口させた回り止め溝と、シート本体と移動フードとの他方に設けられかつこの回り止め溝内に軸方向一端の開口から挿入される回り止め突起とを有し、この回り止め突起と回り止め溝とが係合したときに、シート本体に対して回転することなく軸方向に沿ってのみ移動可能とし、この回り止め突起と回り止め溝とが係合解除したときに、シート本体に対する回転および軸方向移動を可能とするリール脚固定装置であって、前記ナット部材を介して移動フードを移動させたときに、前記回り止め突起を回り止め溝内に案内する案内部を、前記回り止め溝の一端に近接させて設けたことを特徴とする。
【０００８】
更に、上記目的を達成するために、釣竿に設けられ、魚釣用リールの取付脚部が載置されるシート本体と、このシート本体に、シート本体の軸方向に沿って互いに対向させて設けられ、それぞれがリールの取付脚を受け入れる開口を有し、かつ、少なくとも一方がシート本体に対して移動可能な一対のフードと、このシート本体の周部に設けられたネジ部に螺合され、移動可能なフードと共にシート本体に沿って移動可能なナット部材と、シート本体に対する軸方向移動が可能でかつ回転が不能に支持体を介して保持される弾性体と、ナット部材と共に回転し、この弾性体との係脱を繰返す係脱部材とを有し、このナット部材の回動に伴ってクリック音を発生させるクリック機構と、このクリック機構の弾性体を、シート本体に対する軸方向に移動が可能でかつ回転が不能に保持する回り止め機構と、を備え、この回り止め機構は、シート本体と支持体との一方に設けられかつ一端を軸方向に開口させた回り止め溝と、シート本体と支持体との他方に設けられかつ回り止め溝内に軸方向一端の開口から挿入される回り止め突起とを有し、この回り止め突起と回り止め溝とが係合したときに、弾性体をシート本体に対して回転することなく軸方向に沿ってのみ移動可能とし、この回り止め突起と回り止め溝とが係合解除したときに、シート本体に対する回転および軸方向移動を可能とするリール脚固定装置であって、前記ナット部材を介してクリック機構を移動させたときに、前記回り止め突起を回り止め溝内に案内する案内部を、前記回り止め溝の一端に近接させて設けたリール脚固定装置が提供される。
【０００９】
【発明の実施の形態】
図１から図３は、本発明の第１実施形態による釣竿を示す。
図１に示すように、本実施形態に係る釣竿は、リール脚固定装置１を、釣竿の竿管２の手元部（竿尻側端部）に設けている。このリール脚固定装置１は、図１から図３に示すように、内部に竿管２が貫通して装着される合成樹脂等からなる筒状のシート本体４と、シート本体４の外周に装着されかつシート本体４の長手方向に沿って移動可能な摺動部材である移動フード６と、移動フード６に連結されてシート本体４に螺着されると共に移動フード６をシート本体４の長手方向に沿って移動させる回動部材であるナット部材８とを備えている。なお、本実施形態において、シート本体４は、竿管２と別体に形成されて竿管２に接着剤等によって固定されているが、竿管２と一体に形成されていてもよい。
【００１０】
シート本体４は、その基端部に、図示しない魚釣用リールの取付脚部の一方側を受けてこれを係止させる固定フード１０が形成されている。この固定フード１０は、リールの取付脚部が挿入される空間と、この空間内に前記取付脚部を導入するための開口１２とを有している。この開口1２の先端側に、シート本体４は、前記取付脚部を載置するための平坦なリール脚載置部１４を形成されており、このリール脚載置部１４の先端側の部分に移動フード６が摺動自在に装着される。更に、このシート本体４は、このリール脚載置部１４の先端側の僅かに縮径された外周面の一部に雄ネジ１６を形成されている。なお、これらの固定フード１０とリール脚載置部１４と雄ネジ１６とは、シート本体４と一体形成されることが望ましいが、しかし、これに限らず、別体に形成してもよく、また、適宜の形態で取付けることができる。また、固定フード１０は、移動フード６と同様にシート本体４の長手方向に沿って移動できるようになっていてもよい。
【００１１】
移動フード６は、略筒状のフード本体１８と、このフード本体１８の基端部に固着されかつ魚釣用リールの取付脚部の他方側を受けてこれを係止させるリール脚受け部２０とから形成してある。このリール脚受け部２０は、例えば合成樹脂等によって形成されており、リールの取付脚部を収容する空間と、この空間内に取付脚部を導入するための開口２２とを有している。
【００１２】
フード本体１８は金属または剛性の高い合成樹脂等によって形成されており、このフード本体１８の先端側には、ナット部材８と連結する連結部１８ａが形成されている。この連結部１８ａは、一端側がナット部材８に固定された連結部材２４と、回転方向に摺動可能な状態に摩擦係合し、かつ、軸方向に移動不能な状態に噛合い係合している。すなわち、この連結部１８ａは、図２に示すように、その内周面の周方向に沿って突条を延設し、この突条を、連結部材２４の外周面に周方向に延設した溝に滑り嵌めさせてある。勿論、突条とこの突条を嵌合させる溝とを、互いに逆の部材に配置してもよいことは明らかである。
【００１３】
フード本体１８は、その基端部で、開口２２に対して径方向に対向する内周面から、回り止め突起である突起１８ｂが半径方向内方に突出する。この突起１８ｂは、後述するようにシート本体４に軸方向に沿って形成された長溝２６と係合し、シート本体４に対する移動フード６の回転を防止する。したがって、突起１８ｂは、回り止め機構の回り止め突起として作用し、長溝２６は、回り止め機構の回り止め溝として作用し、このため、移動フード６は、その突起１８ｂを長溝２６に係合したときに、竿管２したがってシート本体４に対して回転することなくシート本体４の軸方向（長手方向）に沿ってのみ移動できる。
【００１４】
ナット部材８は、略筒状に形成され、シート本体４の先端側外周に回転可能に装着されている。具体的には、ナット部材８は、その内周面に形成された雌ネジ２８がシート本体４の雄ネジ１６と螺合している。このナット部材８の外周面には、回転を容易とする凹凸状の滑り止め３０（図１）が形成されており、このナット部材８を回転することにより、連結部材２４を介して移動フード６をシート本体４の軸方向に沿って前後動させることができる。
【００１５】
図３に示すように、長溝２６すなわち回り止め機構の回り止め溝は、本実施形態では、雄ネジ１６の基端側で、リール脚載置部１４と径方向に対向する部位に形成してある。この長溝２６が形成される部分は、雄ネジ１６を形成した部分よりも僅かに大径に形成されており、この長溝２６の底壁は、雄ネジ１６の頂部とほぼ同じかあるいはこれよりも僅かに半径方向外方に配置されている。また、この長溝２６の先端側の端部は、この雄ネジ１６を形成した縮径部と長溝２６を形成した大径部との間の環状面で開口しており、この開口部３２を介して、回り止め突起である移動フード６の突起１８ｂを出入りさせることができる。そして、この開口部３２に近接した部位に、この突起１８ｂを長溝２６内に導入するための案内部３４を設けてある。
【００１６】
本実施形態の案内部３４は、図３に示すように、開口部３２を形成した環状面から軸方向に突出する凸部で形成されている。この凸部は、雄ネジ１６のピッチとほぼ同じかあるいはこれよりも短い軸方向長さを有するのが好ましく、また、ナット部材８の締付け方向と対向する側の長溝２６の側壁とほぼ同一の面内に配置されることが好ましい。
【００１７】
次に、上記のリール脚固定装置１を用いてリールを釣竿に固定する方法を説明する。
先ず、ナット部材８をシート本体４に対して一方向に回転させて緩め、このナット部材８と共に移動フード６を先端側（竿の穂先側）に移動させ、固定フード１０から離隔させる。次に、図示しないリールの取付脚部をリール脚載置部１４に載置すると共に、リールの取付脚部の一方側を固定フード１０内に挿入して係止させる。
【００１８】
続いて、ナット部材８をシート本体４に対して他方向に回転させて締付け、移動フード６をナット部材８と共に基端側（竿尻側）に移動させ、固定フード１０に接近させる。この時、移動フード６は、連結部材２４との摩擦係合により、このナット部材８と共に回転しつつ固定フード１０に向けて移動する。そして、移動フード６の突起１８ｂが長溝２６の開口部３２に近接し、案内部３４に係合すると、移動フード６の回転が停止し、その開口２２が固定フード１０の開口１２と軸方向に対向した状態に配置される。
【００１９】
更に、ナット部材８を締付け方向に回転すると、突起１８ｂが長溝２６の開口部３２からこの長溝２６内に導かれ、シート本体４に対して回転不能とされる。この移動フード６は、回転することなく軸方向に沿ってのみ移動可能となるため、その開口２２を固定フード１０の開口１２と軸方向に整合した状態に維持しつつ、移動する。これにより、移動フード６の開口２２内にリールの取付脚部の他方側が挿入され、リール脚受け部２４を介してこの取付脚部がシート本体４および固定フード１０に向けて押圧される。このリール脚受け部２４が所要の力でナット部材８を締付けることにより、移動フード６と固定フード１０との間でリールの取付脚部がきつく挟持される。これにより、リールがリール脚固定装置１を介して釣竿に取り付け固定される。
【００２０】
したがって、本実施形態のリール脚固定装置１およびこれを用いた釣竿は、ナット部材８を回動して雄ネジ１６に締め付けるときに、移動フード６の突起１８ｂが長溝２６に近接すると、案内部３４により自動的に開口部３２から長溝２６内に正確かつ確実に導かれるため、回り止め機構の突起１８ｂおよび長溝２６の損傷、あるいは、シート本体４の雄ネジ１６およびナット部材８の雌ネジ２８の損傷を生じさせることなく、円滑に操作することができ、極めて優れた操作性を有する。
【００２１】
この案内部３４の軸方向長さを雄ネジ１６の１ピッチ以下に形成する場合には、突起１８ｂが案内部３４に係合した後、ナット部材８を１回転以下の僅かな量回転するだけで、この突起１８ｂを確実に長溝２６内に導入することができ、操作性が更に向上すると共に、雄ネジ１６のねじ山の全体を効率的に利用することができる。
【００２２】
なお、移動フード６のフード本体１８は、ナット部材８と同様の材料で形成してもよく、このナット部材８と連結させることなく分離させておくことも可能である。移動フード６がナット部材８から分離している場合には、ナット部材８を回動したときに、このナット部材８と摩擦係合し、このときの摩擦力により、移動フード６がナット部材８と共回りすることが好ましい。
【００２３】
また、上記実施形態では、回り止め機構の突起１８ｂと長溝２６とは、開口２２とリール脚載置部１４との径方向対向位置に限らず、必要に応じて適宜の位置に設けることも可能であり、例えば上述とは逆に長溝２６をナット部材８側に設けると共に、突起１８ｂをシート本体４側に設けてもよい。いずれの場合も、突起１８ｂが長溝２６の底壁に接触することなく、この長溝２６内を案内されることが好ましい。
【００２４】
図４から図８は、第２の実施形態による釣竿を示す。
なお、以下の実施形態は、基本的には上述の第１の実施形態と同様であり、したがって同様な部分には同様な符号を付してその詳細な説明を省略し、主として相違する部分について説明する。
【００２５】
本実施形態に係る釣竿は、図４に示すように、ナット部材８の回動に伴って以下にクリック音と称するカチッっという短い音を繰返し発生させるクリック機構３６を備え、回り止め溝を形成する長溝２６ａが雄ネジ１６上にまで延長されている。
本実施形態のクリック機構３６は、連結部材２４の先端面がナット部材８の基端側の内周部に区画する内側環状溝３８内に収容された弾性機構４０と、この内側環状溝３８の溝底に設けられて弾性機構４０が係脱を繰返す係脱部材としての係合部４２とから形成されている。
【００２６】
特に図６および図７に示すように、係合部４２は、内側環状溝３８の溝底に沿って所定の間隔で形成された複数の小凹部４４を有する。一方、弾性機構４０は、内側環状溝３８内に収容される円環状の支持体４６と、この支持体４６の保持溝４７に収容される弾性体４８とを有する。
弾性体４８は、略Ｕ字状形状を有し、その中央部から外方に凸部４８ａを突出させ、両端部からストッパ部４８ｂを僅かに外方に張出させている。また、支持体４６は、弾性体４８の各ストッパ部４８ｂを支える一対の支持片４６ａと、略中央部に配置されて内方に突出し、シート本体４に延設された長溝２６ａに係合する突起４６ｂとを有する。これらの支持片４６ａは、傾斜した内面（図７の（ａ））を有し、保持溝４７に装着された弾性体４８を両側のストッパ部４８ｂを介して支える。
【００２７】
この弾性機構４０は、弾性体４８を支持部材４６の保持溝４７に装着し、ナット部材８の内側環状溝３８内に収容すると、弾性体４８が、凸部４８ａをこの支持体４６から半径方向外方に突出させ、ナット部材８の係合部４２すなわち内側環状溝３８の底壁に常時係合可能な状態に弾力的に保持される。また、突起４６ｂは、移動フード１８の突起１８ｂと同様に、シート本体４に延設された長溝２６ａに係合し、シート本体４に対する回転を防止しつつ軸方向移動を可能とする。これらの突起４６ｂとストッパ部４８ｂとは、保持溝４７の両側の壁部を連結して、支持体４６の剛性を維持する。
【００２８】
クリック機構３６がこのように形成されるため、ナット部材８が回転されると、この弾性体４８の凸部が係合部４２したがって内側環状溝３８に形成された複数の小凹部４４との係合と離脱とを順に繰返し、軽快なクリック音を発生させる。このような弾性体４８は、例えばバネ鋼、ＳＵＳ、ＢＳ等の金属、セラミックス、合成樹脂で形成するのが好ましく、更に、エラストマー樹脂あるいはゴム材を一部に用いて弾力を付与することもできる。
【００２９】
図８に示すように、支持体４６の突起４６ｂと共に回り止め機構を形成する本実施形態の回り止め溝すなわち長溝２６ａは、雄ネジ１６を形成した部分にまで延長されており、先端側には案内部５０が設けられている。
本実施形態の案内部５０は、長溝２６ａの軸方向先端側で開口する開口部５２に近接配置されたねじ山で形成されている。この案内部５０を形成するねじ山に長溝２６ａを挟んで対向する部分は、ねじ山を切除され、突起１８，４６ｂの周方向導入部５４を形成する。これにより、案内部５０は、ナット部材８の締付け方向と対向する。
【００３０】
このような案内部５０は、雄ネジ１６の最先端側の不完全ネジ部すなわち全周にわたる１のネジピッチを形成しないネジ山のうち、このねじ山の切り始めから長溝２６ａに達するまでの部分を、この雄ネジ１６の谷径と同じかこれよりも半径方向内方位置まで除去することにより、形成することができる。あるいは、これに代え、切り始め部分が長溝２６ａの溝幅内に位置するように、雄ネジ１６をネジ切することで形成することも可能である。この場合には、周方向導入部５４は案内部５０のネジ山と対向する谷部で形成される。
なお、長溝２６ａの溝底は、クリック機構４６を組立てた状態で、突起１８ｂ，４６ｂの先端部が接触しない位置とすることが好ましいことは、上述の実施形態と同様である。
【００３１】
本実施形態におけるリール脚固定装置１の場合も、上述の実施形態と同様な態様でリールを固定することができる。
この場合には、移動フード６を固定フード１０（図１）に向けて基端側に移動する際、ナット部材８を締付けると、先ず移動フードの突起１８ｂが案内部５０に係合して長溝２６ａ内に導かれ、更に、ナット部材８を締付けていくと、クリック機構３６の支持体４６から突出する突起４６ｂが案内部５０から長溝２６ａ内に導かれる。これにより、支持部材４６の回転が不能となり、この支持体４６で支えられた弾性体４８も回転が防止される。したがって、ナット部材８が回転すると、係合部４２すなわち内側環状溝３８の溝底に形成された複数の小凹部４４が、弾性体４８の凸部４８ａとの係合と離脱とを繰返し、軽快なクリック音を発生させる。その他の点については上述の実施形態と同様である。
【００３２】
図９および図１０は、長溝２６ａの一端に設けられた開口部５２に近接してテーパ状部５３を形成した実施形態を示す。
この実施形態におけるテーパ状部５３は、雄ネジ１６の一端側を面取りして谷部から竿管２の外周面まで次第に縮径させて形成してある。このテーパ状部５３の外周面上には、長溝２６ａと軸方向に整合した部位に、上述の移動フード１８の突起１８ｂおよび支持体４６の突起４６ｂを、軸方向および径方向に沿って長溝２６ａの開口部５２まで案内する案内部５５が形成されている。なお、このようなテーパ状部５３は、雄ネジ１６の一端側を面取りすることに代え、雄ネジ１６あるいはシート本体４とは別部材で形成してもよい。
【００３３】
この案内部５５は、周方向導入部５４に対向配置されて突起１８ｂ,４６ｂを軸方向に案内する軸方向壁部５７と、周方向導入部５４および長溝２６ａの溝底と滑らかに連続させて形成され、突起１８ｂ，４６ｂを径方向に案内する傾斜面部５９とを有する。この傾斜面部５９は、雄ネジ１６の谷部とほぼ同径となる位置すなわち雄ネジ１６の谷径とほぼ同径（谷径との差が＋０．１ｍｍ以下）に形成するのが好ましい。
【００３４】
この実施形態においては、長溝２６ａの溝底を竿管２あるいはシート本体４の外周面よりも半径方向外方に形成した場合であっても、突起１８ｂ，４６ｂは周方向導入部５４により案内部５５に滑らかに案内され、更に、この案内部５５の軸方向壁部５７と傾斜面部５９とで軸方向および径方向に案内されるため、突起１８ｂ，４６ｂが常に長溝２６ａまで滑らかに案内される。これにより、特に、支持体４６の突起４６ｂおよび長溝２６ａが係合する際の破損が防止される。
【００３５】
なお、上述の実施形態では、クリック機構３６をナット部材８内に設けた状態で説明したが、これに限るものではなく、例えば連結部材２４等必要に応じて適宜の１または複数の部材に設けることも可能なことは明らかである。
図１１は、変形例によるクリック機構３６ａを示し、このクリック機構３６ａは、移動フード６の例えばリール脚受け部２０に軸方向に付勢される弾性体４１を配設し、ナット部材８には、上述の小凹部と同様な係脱部材４５をこの弾性体４１と対向配置して形成してある。このクリック機構３６ａも、ナット部材８を回動したときに、弾性体４１と係脱部材４５の小凹部との係脱が繰返され、軽快なクリック音を発生する。また、意図に反してナット部材８が簡単に回動するのを防止するのも上述のクリック機構３６と同様である。
【００３６】
図１２は、移動フード６ａのフード本体１８とナット部材８とを一体的に形成した変形例を示す。この変形例の移動フード６ａでは、リールの取付脚部を導入するための開口２２が固定フード１０に対向する側で、フード本体１８の全周に沿って形成してある。ナット部材８を雄ネジ１６に沿って回転し、固定フード１０側に向けて移動すると、リールの取付脚部の一端をこの開口２２内に収容した状態で、フード本体１８もこのナット部材８と共に固定フード１０に向けて移動する。また、ナット部材８を逆方向に回転すると、フード本体１８もナット部材８と共に移動し、固定フード１０から離隔する。
【００３７】
この変形例では、上述の第２実施形態と同様なクリック機構３６が移動フード６ａの内部に配置してある。このクリック機構１０は、予め別部材として個々に形成したナット部材８とフード本体１８との一方あるいは双方に、内側環状溝３８を形成し、この内側環状溝３８内にクリック機構３６を収容した後に、ナット部材８とフード本体１８とを一体的に結合することにより、移動フード６ａ内に配置することができる。符号９は、実釣時に釣竿を握持し易くするための柔軟部材を示す。
【００３８】
このクリック機構３６も、移動フード６ａしたがってナット部材８を雄ネジ１６に螺合させる際、回り止め突起４６ｂが図９および図１０に示すものと同様な導入部５４から案内部５５に滑らかに案内され、この案内部５５では軸方向および径方向に案内されつつ回り止め溝である長溝２６ａ内に滑らかに案内される。
【００３９】
図１３から図１５は、更に他の実施形態による釣竿を示す。
本実施形態における釣竿は、回り止め突起の案内部を元竿管の基端部に形成したものである。
本実施形態の釣竿は、元竿管である竿管２の基端部に螺合する尻栓５６と、この尻栓５６に回動自在に摩擦係合する中竿保持部材５８と、この中竿保持部材５８内を摺動自在の中竿６０とを備える。この中竿保持部材５８は、基端部外周に形成した周方向の突条を、尻栓５６の内周面に形成した周方向溝に滑り嵌めさせることにより、回転方向に摺動可能で、かつ、この周方向溝の溝幅の範囲で軸方向にも摺動可能に、尻栓５６に連結されており、中竿を引き出す際、この中竿を回動させながら引き出しても尻栓５６に緩みが生じるのを阻止する。これにより、この釣竿は、尻栓５６に緩みを生じさせることなく、中竿を長さ調節可能とし、あるいは、収納時に保持可能に形成されている。
【００４０】
そして、本実施形態では、回り止め機構が竿管２の基端部内周に形成した雌ネジ６２の先端側に配置した回り止め溝である長溝６４と、中竿保持部材５８の先端部から外方に突出する突起６６とで形成されている。尻栓５６を竿管２に螺合する際、回り止め突起である突起６６を長溝６４内に導きいれる案内部６８がこの長溝６４の開口部６５の近部から軸方向に突出している。この案内部６８は、第１実施形態の案内部と同様に、開口部６５を形成した環状面から軸方向に突出する凸部で形成されている。この凸部は、雌ネジ６２のピッチとほぼ同じかあるいはこれよりも短い軸方向長さを有するのが好ましく、また、尻栓５６の締付け方向と対向する側の長溝６４の側壁とほぼ同一の面内に配置されることが好ましい。
【００４１】
他の点ついては、上述の実施形態と同様であり、他の回り止め機構と同様に、突起６６を長溝６４内に案内する。
なお、上記の各実施形態では、回り止め機構をそれぞれ１つの突起と１つの長溝とで形成してあるが、これに限らず、これらの突起と長溝とをそれぞれ複数設けてもよく、この場合には、案内部を全ての長溝に設けることなく、いずれか１の長溝に設けるだけでもよい。また、上記の各実施形態では、摺動部材として移動フードおよび中竿保持部材を例示したが、本発明の摺動部材は、このように、直接竿管に対して直接摺動する部材の他にも、竿管との間に他の部材を介在させて間接的に摺動する部材であってもよい。更に、このような摺動部材と回動部材との係合は、摩擦係合の他にも、同様に機能するものであれば、滑り係合あるいは噛合い係合のような直接係合だけでなく、他の部材を介して間接的に連結されるものであってもよい。勿論、上述の各実施形態あるいは変形例の種々の部材をそれぞれ適宜に組合せて用いることも可能である。

DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a fishing rod according to a first embodiment of the present invention.
As shown in FIG. 1, the fishing rod according to the present embodiment is provided with the reel leg fixing device 1 at a hand portion (a butt end side end portion) of the rod 2 of the fishing rod. As shown in FIGS. 1 to 3, the reel leg fixing device 1 is mounted on a cylindrical sheet body 4 made of a synthetic resin or the like in which a tub tube 2 is inserted and mounted on an outer periphery of the sheet body 4. The movable hood 6 is a sliding member that is movable along the longitudinal direction of the seat body 4, and is coupled to the movable hood 6 and screwed to the seat body 4, and the movable hood 6 is connected to the longitudinal direction of the seat body 4. And a nut member 8 which is a rotating member to be moved along. In the present embodiment, the sheet body 4 is formed separately from the tub tube 2 and is fixed to the tub tube 2 with an adhesive or the like, but may be formed integrally with the tub tube 2.
[0010]
The seat body 4 is formed with a fixed hood 10 at the base end portion for receiving and locking one side of a mounting leg portion of a fishing reel (not shown). The fixed hood 10 has a space in which the mounting legs of the reel are inserted, and an opening 12 for introducing the mounting legs into the space. At the front end side of the opening 12, the seat body 4 is formed with a flat reel leg mounting portion 14 for mounting the mounting leg portion, and at the front end side portion of the reel leg mounting portion 14. A movable hood 6 is slidably mounted. Further, the seat body 4 is formed with a male screw 16 on a part of the outer peripheral surface slightly reduced in diameter on the front end side of the reel leg mounting portion 14. The fixed hood 10, the reel leg mounting portion 14, and the male screw 16 are preferably formed integrally with the seat body 4, but are not limited thereto, and may be formed separately. Moreover, it can be attached in an appropriate form. Further, the fixed hood 10 may be configured to be movable along the longitudinal direction of the seat body 4 similarly to the movable hood 6.
[0011]
The movable hood 6 has a substantially cylindrical hood main body 18 and a reel leg receiving portion 20 which is fixed to the base end portion of the hood main body 18 and receives the other side of the mounting leg portion of the fishing reel and locks it. It is formed from. The reel leg receiving portion 20 is formed of, for example, synthetic resin, and has a space for accommodating the mounting leg portion of the reel, and an opening 22 for introducing the mounting leg portion into this space.
[0012]
The hood main body 18 is formed of metal, a highly rigid synthetic resin, or the like, and a connecting portion 18 a that is connected to the nut member 8 is formed on the distal end side of the hood main body 18. The connecting portion 18a is frictionally engaged with a connecting member 24 having one end fixed to the nut member 8 so as to be slidable in the rotational direction, and meshed and engaged so as not to be movable in the axial direction. Yes. That is, as shown in FIG. 2, the connecting portion 18 a extends a protrusion along the circumferential direction of the inner peripheral surface, and extends this protrusion on the outer peripheral surface of the connecting member 24 in the circumferential direction. Sliding in the groove. Of course, it is obvious that the ridge and the groove into which the ridge is fitted may be disposed on members opposite to each other.
[0013]
In the hood main body 18, a protrusion 18 b that is a rotation prevention protrusion protrudes inward in the radial direction from an inner circumferential surface facing the opening 22 in the radial direction at the base end portion. The protrusion 18b engages with a long groove 26 formed in the seat body 4 along the axial direction, as will be described later, and prevents the movable hood 6 from rotating relative to the seat body 4. Therefore, the protrusion 18b acts as a rotation prevention protrusion of the rotation prevention mechanism, and the long groove 26 acts as a rotation prevention groove of the rotation prevention mechanism. For this reason, the movable hood 6 engages the protrusion 18b with the long groove 26. Sometimes, it can move only along the axial direction (longitudinal direction) of the sheet body 4 without rotating with respect to the soot tube 2 and thus the sheet body 4.
[0014]
The nut member 8 is formed in a substantially cylindrical shape and is rotatably mounted on the outer periphery on the front end side of the seat body 4. Specifically, the nut member 8 has a female screw 28 formed on an inner peripheral surface thereof screwed with the male screw 16 of the seat body 4. An uneven slip stopper 30 (FIG. 1) that facilitates rotation is formed on the outer peripheral surface of the nut member 8. By rotating the nut member 8, the movable hood 6 is connected via the connecting member 24. Can be moved back and forth along the axial direction of the seat body 4.
[0015]
As shown in FIG. 3, the long groove 26, that is, the anti-rotation groove of the anti-rotation mechanism, is formed on the base end side of the male screw 16 in a portion facing the reel leg mounting portion 14 in the radial direction in this embodiment. is there. The portion where the long groove 26 is formed is formed to have a slightly larger diameter than the portion where the male screw 16 is formed, and the bottom wall of the long groove 26 is substantially the same as or more than the top of the male screw 16. Located slightly outward in the radial direction. Further, the end of the long groove 26 on the front end side opens at an annular surface between the reduced diameter portion where the male screw 16 is formed and the large diameter portion where the long groove 26 is formed. Thus, the protrusion 18b of the moving hood 6 that is a rotation prevention protrusion can be moved in and out. A guide portion 34 for introducing the protrusion 18b into the long groove 26 is provided at a portion close to the opening 32.
[0016]
As shown in FIG. 3, the guide portion 34 of the present embodiment is formed by a convex portion that protrudes in the axial direction from the annular surface on which the opening 32 is formed. The convex portion preferably has an axial length that is substantially the same as or shorter than the pitch of the male screw 16, and is substantially the same as the side wall of the long groove 26 on the side facing the tightening direction of the nut member 8. It is preferable to arrange in the plane.
[0017]
Next, a method for fixing a reel to a fishing rod using the reel leg fixing device 1 will be described.
First, the nut member 8 is rotated and loosened in one direction with respect to the seat body 4, and the moving hood 6 is moved together with the nut member 8 to the distal end side (the tip side of the heel) and separated from the fixed hood 10. Next, the mounting leg portion of the reel (not shown) is placed on the reel leg mounting portion 14, and one side of the mounting leg portion of the reel is inserted into the fixed hood 10 and locked.
[0018]
Subsequently, the nut member 8 is rotated and tightened in the other direction with respect to the seat body 4, and the moving hood 6 is moved together with the nut member 8 to the base end side (buttock side) to approach the fixed hood 10. At this time, the movable hood 6 moves toward the fixed hood 10 while rotating together with the nut member 8 due to frictional engagement with the connecting member 24. When the protrusion 18b of the moving hood 6 comes close to the opening 32 of the long groove 26 and engages with the guide 34, the rotation of the moving hood 6 stops, and the opening 22 extends axially with the opening 12 of the fixed hood 10. Arranged in an opposing state.
[0019]
Further, when the nut member 8 is rotated in the tightening direction, the projection 18b is guided into the long groove 26 from the opening 32 of the long groove 26, and cannot be rotated with respect to the sheet body 4. Since the moving hood 6 can move only along the axial direction without rotating, the moving hood 6 moves while maintaining its opening 22 aligned with the opening 12 of the fixed hood 10 in the axial direction. Thereby, the other side of the mounting leg portion of the reel is inserted into the opening 22 of the movable hood 6, and the mounting leg portion is pressed toward the seat body 4 and the fixed hood 10 via the reel leg receiving portion 24. The reel leg receiving portion 24 tightens the nut member 8 with a required force, whereby the mounting leg portion of the reel is tightly held between the movable hood 6 and the fixed hood 10. Accordingly, the reel is attached and fixed to the fishing rod via the reel leg fixing device 1.
[0020]
Therefore, the reel leg fixing device 1 and the fishing rod using the same according to the present embodiment are such that when the projection 18b of the moving hood 6 comes close to the long groove 26 when the nut member 8 is rotated and fastened to the male screw 16, the guide portion 34 is automatically and accurately guided from the opening 32 into the long groove 26, so that the protrusion 18 b and the long groove 26 of the anti-rotation mechanism are damaged, or the male screw 16 of the seat body 4 and the female screw 28 of the nut member 8. It can be operated smoothly without causing any damage, and has extremely excellent operability.
[0021]
When the axial length of the guide portion 34 is formed to be equal to or less than one pitch of the male screw 16, the nut member 8 is only rotated by a slight amount of one turn or less after the protrusion 18b is engaged with the guide portion 34. Thus, the protrusion 18b can be reliably introduced into the long groove 26, and the operability is further improved, and the entire thread of the male screw 16 can be used efficiently.
[0022]
Note that the hood body 18 of the movable hood 6 may be formed of the same material as the nut member 8, and can be separated without being connected to the nut member 8. When the moving hood 6 is separated from the nut member 8, when the nut member 8 is rotated, the moving hood 6 is frictionally engaged with the nut member 8. It is preferable to rotate together.
[0023]
Further, in the above-described embodiment, the protrusion 18b and the long groove 26 of the rotation preventing mechanism are not limited to the radially opposed positions of the opening 22 and the reel leg mounting portion 14, but can be provided at appropriate positions as necessary. For example, contrary to the above, the long groove 26 may be provided on the nut member 8 side, and the protrusion 18b may be provided on the seat body 4 side. In any case, it is preferable that the projection 18b is guided in the long groove 26 without contacting the bottom wall of the long groove 26.
[0024]
4 to 8 show a fishing rod according to the second embodiment.
The following embodiment is basically the same as the above-described first embodiment. Therefore, the same reference numerals are given to the same parts, and the detailed description thereof is omitted, and different parts are mainly described. explain.
[0025]
As shown in FIG. 4, the fishing rod according to the present embodiment includes a click mechanism 36 that repeatedly generates a short clicking sound referred to as a click sound as the nut member 8 is rotated, and forms a detent groove. A long groove 26 a extending to the male screw 16 is extended.
The click mechanism 36 of this embodiment includes an elastic mechanism 40 housed in an inner annular groove 38 in which the distal end surface of the connecting member 24 is partitioned in the inner peripheral portion on the proximal end side of the nut member 8, and the inner annular groove 38. The elastic mechanism 40 is provided at the groove bottom and is formed from an engaging portion 42 as an engaging / disengaging member that repeats engaging / disengaging.
[0026]
In particular, as shown in FIGS. 6 and 7, the engaging portion 42 has a plurality of small recesses 44 formed at predetermined intervals along the groove bottom of the inner annular groove 38. On the other hand, the elastic mechanism 40 includes an annular support body 46 accommodated in the inner annular groove 38 and an elastic body 48 accommodated in the holding groove 47 of the support body 46.
The elastic body 48 has a substantially U-shape, and protrudes outwardly from the central portion of the elastic body 48 and slightly protrudes the stopper portion 48b outward from both ends. The support 46 is engaged with a pair of support pieces 46 a that support the stoppers 48 b of the elastic body 48 and a long groove 26 a that is disposed substantially at the center and protrudes inward, and extends in the seat body 4. And a protrusion 46b. These support pieces 46a have an inclined inner surface ((a) in FIG. 7), and support the elastic body 48 mounted in the holding groove 47 via stopper portions 48b on both sides.
[0027]
In the elastic mechanism 40, when the elastic body 48 is mounted in the holding groove 47 of the support member 46 and accommodated in the inner annular groove 38 of the nut member 8, the elastic body 48 causes the protrusion 48 a to extend in the radial direction from the support body 46. It protrudes outward and is elastically held in a state in which it can always be engaged with the engaging portion 42 of the nut member 8, that is, the bottom wall of the inner annular groove 38. Similarly to the protrusion 18 b of the moving hood 18, the protrusion 46 b engages with a long groove 26 a extending in the sheet main body 4, and enables axial movement while preventing rotation with respect to the sheet main body 4. These protrusions 46 b and the stopper portion 48 b connect the wall portions on both sides of the holding groove 47 to maintain the rigidity of the support body 46.
[0028]
Since the click mechanism 36 is formed in this manner, when the nut member 8 is rotated, the convex portion of the elastic body 48 is engaged with the engaging portion 42 and thus the plurality of small concave portions 44 formed in the inner annular groove 38. Repeats the combination and separation in order to generate a light click sound. Such an elastic body 48 is preferably formed of, for example, a metal such as spring steel, SUS, or BS, ceramics, or a synthetic resin, and can further impart elasticity by using an elastomer resin or a rubber material in part. .
[0029]
As shown in FIG. 8, the anti-rotation groove or long groove 26a of the present embodiment, which forms the anti-rotation mechanism together with the protrusion 46b of the support 46, is extended to the portion where the male screw 16 is formed. A guide unit 50 is provided.
The guide part 50 of the present embodiment is formed of a screw thread that is disposed in the vicinity of an opening 52 that is opened on the tip end side in the axial direction of the long groove 26a. A portion of the thread forming the guide portion 50 facing the long groove 26a is cut off to form a circumferential introduction portion 54 of the protrusions 18 and 46b. Thereby, the guide part 50 opposes the tightening direction of the nut member 8.
[0030]
Such a guide portion 50 is a portion of the incomplete screw portion on the most distal side of the male screw 16, that is, a portion from the start of the cutting of the screw thread to the long groove 26 a among the screw threads that do not form one screw pitch. It can be formed by removing to the radially inner position equal to or smaller than the valley diameter of the male screw 16. Alternatively, it may be formed by threading the male screw 16 so that the cutting start portion is positioned within the groove width of the long groove 26a. In this case, the circumferential introduction portion 54 is formed by a trough that faces the thread of the guide portion 50.
It is to be noted that the groove bottom of the long groove 26a is preferably located at a position where the tip portions of the protrusions 18b and 46b do not come into contact with the click mechanism 46 assembled.
[0031]
In the case of the reel leg fixing device 1 in the present embodiment, the reel can be fixed in the same manner as in the above-described embodiment.
In this case, when the nut member 8 is tightened when the movable hood 6 is moved toward the fixed hood 10 (FIG. 1), first, the projection 18b of the movable hood first engages with the guide portion 50 to form a long groove. When the nut member 8 is further tightened, the protrusion 46b protruding from the support 46 of the click mechanism 36 is guided from the guide portion 50 into the long groove 26a. Thereby, the support member 46 cannot be rotated, and the elastic body 48 supported by the support body 46 is also prevented from rotating. Therefore, when the nut member 8 rotates, the plurality of small recesses 44 formed in the engagement portion 42, that is, the groove bottom of the inner annular groove 38, repeatedly engage and disengage from the protrusion 48 a of the elastic body 48. A simple click sound. Other points are the same as in the above-described embodiment.
[0032]
9 and 10 show an embodiment in which a tapered portion 53 is formed in the vicinity of an opening 52 provided at one end of the long groove 26a.
The tapered portion 53 in this embodiment is formed by chamfering one end side of the male screw 16 and gradually reducing the diameter from the valley portion to the outer peripheral surface of the soot tube 2. On the outer peripheral surface of the tapered portion 53, the protrusion 18b of the moving hood 18 and the protrusion 46b of the support 46 are arranged in a position aligned with the long groove 26a in the axial direction, along the axial direction and the radial direction. A guide portion 55 that guides to the opening portion 52 is formed. Such a tapered portion 53 may be formed by a member different from the male screw 16 or the seat body 4 instead of chamfering one end side of the male screw 16.
[0033]
The guide portion 55 is disposed opposite to the circumferential introduction portion 54 and smoothly continues to the axial wall portion 57 that guides the protrusions 18b and 46b in the axial direction, and the circumferential introduction portion 54 and the groove bottom of the long groove 26a. And an inclined surface portion 59 that guides the protrusions 18b and 46b in the radial direction. The inclined surface portion 59 is preferably formed at a position that is substantially the same diameter as the valley portion of the male screw 16, that is, substantially the same diameter as the valley diameter of the male screw 16 (the difference from the valley diameter is +0.1 mm or less).
[0034]
In this embodiment, even when the groove bottom of the long groove 26 a is formed radially outward from the outer peripheral surface of the vertical tube 2 or the sheet body 4, the protrusions 18 b and 46 b are guided by the circumferential introduction portion 54. Further, the projections 18b and 46b are always smoothly guided to the long groove 26a because the guide portion 55 is guided in the axial direction and the radial direction by the axial wall portion 57 and the inclined surface portion 59 of the guide portion 55. . Thereby, especially the damage at the time of engaging the protrusion 46b and the long groove 26a of the support body 46 is prevented.
[0035]
In the above-described embodiment, the click mechanism 36 is provided in the nut member 8. However, the present invention is not limited to this. For example, the connection member 24 is provided on one or more appropriate members as necessary. Obviously it is also possible.
FIG. 11 shows a click mechanism 36 a according to a modified example. This click mechanism 36 a is provided with an elastic body 41 that is urged in the axial direction by, for example, the reel leg receiving portion 20 of the moving hood 6. An engaging / disengaging member 45 similar to the above-described small concave portion is formed so as to face the elastic body 41. In the click mechanism 36a, when the nut member 8 is rotated, the engagement / disengagement between the elastic body 41 and the small recess of the engagement / disengagement member 45 is repeated, and a light click sound is generated. Further, similarly to the click mechanism 36 described above, it is possible to prevent the nut member 8 from being easily rotated unintentionally.
[0036]
FIG. 12 shows a modification in which the hood main body 18 and the nut member 8 of the movable hood 6a are integrally formed. In the movable hood 6a of this modification, the opening 22 for introducing the mounting leg portion of the reel is formed along the entire circumference of the hood main body 18 on the side facing the fixed hood 10. When the nut member 8 is rotated along the male screw 16 and moved toward the fixed hood 10, the hood main body 18 also moves together with the nut member 8 in a state where one end of the mounting leg portion of the reel is accommodated in the opening 22. Move toward the fixed hood 10. When the nut member 8 is rotated in the reverse direction, the hood body 18 also moves with the nut member 8 and is separated from the fixed hood 10.
[0037]
In this modification, a click mechanism 36 similar to that of the second embodiment described above is disposed inside the movable hood 6a. The click mechanism 10 has an inner annular groove 38 formed in one or both of the nut member 8 and the hood body 18 individually formed as separate members in advance, and the click mechanism 36 is accommodated in the inner annular groove 38. The nut member 8 and the hood main body 18 are integrally coupled to each other so that the nut member 8 and the hood main body 18 can be disposed in the movable hood 6a. Reference numeral 9 denotes a flexible member for making it easier to grip a fishing rod during actual fishing.
[0038]
Also in this click mechanism 36, when the moving hood 6a and hence the nut member 8 are screwed into the male screw 16, the detent protrusion 46b smoothly guides from the introduction portion 54 similar to that shown in FIGS. 9 and 10 to the guide portion 55. The guide portion 55 is smoothly guided in the long groove 26a which is a rotation preventing groove while being guided in the axial direction and the radial direction.
[0039]
