Description

【０００１】
【発明の属する技術分野】
本発明は、魚釣りに用いる釣竿に関する。詳しくは、元竿の竿元側に出し入れ自在に連結される延伸竿を有し、釣竿全体の長さを容易に調整可能な釣竿に関する。
【０００２】
【従来の技術】
一般に、釣竿は複数の竿体を振出形式若しくは並継形式等によって連結して一本の釣竿となっている。そして、その用途にあわせて様々なタイプの釣竿が多様な機能を備えて提供されている。例えば、鮎釣り用の鮎竿や渓流竿などの延べ竿に於いては、仕掛けに掛かった魚を取込易くするために、釣竿の全長を釣り操作時に素早く変更できるような機能が付与されている。
【０００３】
例えば、ある種の従来の鮎竿等は、元竿の竿元側端部に別途延伸竿が連結されている。この延伸竿は元竿内に収納した状態（収納状態）と、元竿内から手元側に引き出した状態（延伸状態）との何れにあっても元竿に連結固定可能である。そして、釣り操作の最中に状況に応じて釣人は延伸竿を出し入れして釣竿全体の長さを調整して釣りを行う（例えば、特許文献１等参照）。具体的には、従来のこのように釣竿の長さを調整可能な釣竿にあっては、収納状態に於いて、元竿の竿元側端部の内周面と延伸竿の竿元側の周面とで相互に嵌着する構造になっている。
【０００４】
【特許文献１】
実用新案登録第３０２２４１１号公報（図２，図３）
【０００５】
【発明が解決しようとする課題】
しかし、上述のように、この種の釣竿では釣り操作の最中に（特に、鮎竿などでは川の中で）状況に応じて延伸材を元竿に出し入れするので、元竿の竿元側や延伸竿の竿元側にはゴミや小石・水などが付着し易い。このため、操作中に十分な嵌着力を確保できなくなり若しくは逆に固着等が生じ易い。さらに、繰り返し使用していると嵌着力が低下し易い。
【０００６】
本発明の課題は、元竿と延伸竿との間で釣竿全体の長さを変化させることができ、且つ、当該竿同士の十分な嵌着力を維持できる釣竿を提供することにある。
【０００７】
【課題を解決するための手段】
発明１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、元竿と、元竿の竿元側に前記元竿内に出入自在に連結され、元竿内に収納された収納状態，元竿の竿元側に引き出された延伸状態の何れにおいても元竿に固定可能な延伸竿とを備えている。
【０００８】
この元竿は、全体として先細りテーパが施された筒状の本体部と、本体部の竿元側に脱着自在に連結され元竿の竿元側端部より挿入されるパイプ状部材であり、その内周面に逆テーパ部分を有する尻栓とを有している。
元竿はその本体部の軸方向中央付近の内周面に径の変化しない部分が形成されている。
一方、延伸竿は、穂先側端部外周面に径の変化しない他の部分より大径に形成される嵌合雄部が形成され元竿内に出入される挿入部と、挿入部の竿元側に連結されるグリップ部とを有している。そして、
収納状態にあっては、元竿内に延伸竿が竿元側から挿入可能であるとともに、本体部の軸方向中央付近の内周面の径の変化しない部分と延伸竿の嵌合雄部とが嵌着可能であり、
延伸状態にあっては、尻栓が嵌合雄部に嵌着可能になっている。
【０００９】
この釣竿の延伸竿は元竿内に収納した状態（収納状態）と、元竿内から手元側に引き出した状態（延伸状態）との何れにあっても元竿に連結固定可能である。釣りを行っている最中において、延伸竿を元竿から手元側に引き出して延伸状態とし、若しくは、延伸竿を元竿内に押し込んで収納状態とし、状況に応じて釣竿全体の長さを調整して釣りを行う。具体的には、各状態において元竿と延伸竿とは以下のような態様で連結固定されている。
【００１０】
まず、収納状態にあっては、元竿内に竿元側から延伸竿が挿入され、延伸竿の穂先側端部の嵌合雄部が元竿の本体部の軸方向中央付近の内周面に嵌着する。一方、延伸状態にあっては、元竿内から竿元側に延伸竿が引き出されると、延伸竿の穂先側端部の嵌合雄部は元竿の竿元側端部に至りパイプ状の尻栓の内周面に嵌着する。
【００１１】
このように、収納状態において、元竿の軸方向中央付近内周面で延伸竿の嵌合雄部を嵌着させ、また、延伸状態においても、元竿の竿元側の内部で延伸竿の嵌合雄部を嵌合させる。よって、嵌合部分にゴミや水などが付着し難く、嵌合力の低下や固着なども生じにくい。
発明２の釣竿は、発明１の釣竿であって、尻栓は内周面に竿元側ほど径が小さくなる逆テーパ部分を有している。また、延伸竿の挿入部の嵌合雄部は径の変化しない部分とその竿元側に連続して竿元側ほど径が小さくなる逆テーパ部分とを有している。そして、収納状態にあっては、元竿の本体部の径の変化しない部分と嵌合雄部の径の変化しない部分とが嵌着可能であり、前記延伸状態にあっては、尻栓の逆テーパ部分と嵌合雄部の逆テーパ部分とが嵌着可能となる。
【００１２】
この釣竿では、いわゆる収納状態と延伸状態とにおいて、それぞれ嵌着する部分を異にすることで、それぞれの状態に応じた良好な嵌着状態を演出している。また、脱着を繰り返しても、相互の嵌着部分の劣化程度も軽減する。
なお、ここで径の変化しない部分というのは、軸方向の一定範囲において径の変化しない部分若しくは極めて微妙に径が変化するに過ぎない部分である。逆テーパ部分とは手元側ほど小径化するようなテーパを意味する。
【００１３】
発明３の釣竿は、発明１または２の釣竿であって、元竿の尻栓は竿元側端部内周面に雌ねじ部を有している。また、延伸竿は挿入部の竿元側端部外周面の雌ねじ部に螺着可能な雄ねじ部を有している。
この釣竿では、延伸竿の嵌合雄部が元竿の径の変化しない部分に嵌合した収納状態において、さらに、元竿と延伸竿とを完全に固定したい場合に、雄ねじ部を雌ねじ部に螺着させる。
【００１４】
発明４の釣竿は、発明３の釣竿であって、延伸竿は挿入部の竿元側の外周面に塗装層を有し、塗装層は前記元竿の尻栓の内周面に仮嵌着する。
この釣竿では、挿入竿の挿入部が元竿の竿元側端部から挿入されると、まず、塗装層が尻栓の内周面に仮に嵌着する。その後、必要に応じて、雌ねじ部と雄ねじ部とを螺着して本止め状態とする。釣りを行っている最中に、状況に応じて仮止め状態と本止め状態とを使い分ける。また、本止め状態にあっては嵌着する部分が２点となるのでがたつきが生じにくい。
【００１５】
発明４の釣竿は、発明２又は３の釣竿であって、雄ねじ部及び雌ねじ部は多条ねじである。
この釣竿では、特に雄ねじ部および雌ねじ部に多条ねじを利用しており、元竿と延伸竿とをわずかに相互に回転させるだけで、雄ねじ部と、雌ねじ部とを螺着させることができる。また、釣りを終えて完全に釣竿を収納した際にも、多条ねじで竿体相互を十分に固定でき、不用意に延伸竿が元竿から飛び出してしまうようなこともない。
【００１６】
【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。
本発明の第１実施形態を採用した釣竿は、鮎釣り等に用いられる釣竿であり、図１に示すように、元竿１と、元竿１の竿元側から出し入れ自在に連結される延伸竿２とを有している。また、元竿１の穂先側にも、複数の竿体（中竿，穂先竿等）が連結される（図示せず）。これらの各竿体は炭素繊維等の強化繊維に合成樹脂を含浸させたプリプレグ素材を焼成して形成されている。
【００１７】
元竿１より穂先側の各竿体はいわゆる振出形式で連結されており、穂先側の竿体から順次竿元側に位置する竿体内に出し入れ自在である。それぞれ穂先側に位置する竿体の竿元側端部外周面を竿元側に隣接する竿体の穂先側内周面に嵌着させて相互に固定可能である。もっとも穂先側に位置する穂先竿の穂先側端部には釣糸係止具が配置されている。また、元竿１とその竿元側に位置する延伸竿２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いる。
【００１８】
（元竿１について）
元竿１は全体として穂先側ほど小径化するようなテーパが施された筒状体である。もっとも、軸方向中央付近の内周面に於いては、部分的に径の変化しない部分が設けられている（図２：Ｘ範囲参照）。即ち、元竿１は、穂先側から順次竿元側に向かって内径も拡径してゆくテーパが施されている（Ａ範囲参照）。その中の一部分においては、その内径が部分的に変化しない（Ｘ範囲）。そして、Ｘ範囲の竿元側に連続する部分においては、Ａ範囲のテーパに再び合致するように、急テーパ部分が形成される（Ｂ範囲）。この径の変化しない部分が、後述する延伸竿２の穂先側端部と収納状態において嵌着する（図２参照）。
【００１９】
図３に示すように、この元竿１の竿元側端部には尻リング３と尻栓４とが脱着自在に装着されている。
尻リング３は、金属（アルミニウム合金）製の円筒型の部材であり、竿元側端部内周面はねじ溝が形成され第１雌ねじ部分となっている。元竿１の竿元側端部の外周面は、竿元側端縁より一部が削られて凹入しており、この凹入した部分を尻リング３が覆うようにして、尻リング３の穂先側が凹入した部分に装着されている。この際、尻リング３の外径は元竿１の外径に合致するように設定するのがよい。
【００２０】
尻栓４は硬質合成樹脂製の円筒型の部材である。穂先側は外径が一段小径化した挿入部分となっており、竿元側端部は外径が上述の尻リング３の外径に合致するように一段大径化した頭部分となっている。挿入部分は元竿１の竿元側からその内部に挿入される部分である。そして、外周面は径の変化しない面であり、内周面は竿元側ほど小径化する逆テーパ部分とその竿元側に連続する径の変化しない部分とから構成されている。この尻栓４の内周面の逆テーパ部分が、後述する延伸竿２の穂先側端部と延伸状態において嵌着し、径の変化しない部分が挿入状態において延伸竿と嵌着する（図３参照）。また、挿入部分の竿元側端部の頭部分との段差付近には、上述の尻リング３の第１雌ねじ部分に螺合するねじ溝が形成されて第１雄ねじ部分となっている。また、尻栓４の竿元側端部内周面（頭部分の内周）では、内径が一段大径化してねじ溝が形成されて第２雌ねじ部分が形成されている。この第２雌ねじ部分のねじ溝については、後述する。
【００２１】
このように、この尻栓４は第１雄ねじ部分を尻リング３の第１雌ねじ部分に螺着することで、尻リング３を介して元竿１に脱着自在に装着されている。
（延伸竿２について）
図４に示すように、延伸竿２は、元竿１の竿元側からその内部に挿入される挿入部６と、挿入部６の竿元側に連結される太径のパイプ状部材であるグリップ部７とからなる。
【００２２】
挿入部６は元竿１内に挿入可能な外径の筒状体である。挿入部６は、径の変化のないもの若しくは竿元側ほど小径化するような逆テーパを施しておく。もっとも、穂先側端部の外周面は、軸方向の一定範囲で外径が径が変化せず他の部分より大径化された部分と（この部分は塗装されている）、その竿元側に連続して竿元側ほど小径化する逆テーパ部分とを有する。そして、ここが嵌合雄部６ａとなっている（図２，３参照）。この嵌合雄部６ａの外径は、径の変化しない部分が上述の元竿１の径の変化しない部分Ｘと，逆テーパ部分が尻栓４の逆テーパの内径に合致する。
【００２３】
この挿入部６は、穂先側端部に配置されるゴムカバー８と、竿元側端部外周面に装着されるねじ金具９とを有する。また、ねじ金具９の穂先側に隣接する周面には塗料層１０が形成されている。
ゴムカバー８は周知の弾性ゴムから形成され軸方向に中空が貫通する円筒型の部材である。竿元側の外周面が一部削られて、ここが挿入部６の穂先側端部に挿入されて接着剤等で固定されている。ゴムカバー８の穂先側の内径は穂先側端部に向かって拡径するテーパが施されている。また、穂先側の端部からは軸方向に「割り」も形成する。このゴムカバー８は、元竿１の穂先側に振出形式に連結されている中竿などを元竿１内に収納する際に、円滑に中竿などを挿入部内に導くためのものである。
【００２４】
ねじ金具９は、挿入部６の竿元側端部の外周面に（グリップ部７の穂先側に隣接して）装着されているリング状の部材である。挿入部６に対して接着又は螺着等周知の手法で装着される。ねじ金具９の外周面には多条ねじ溝が形成されている。多条ねじのネジ幅や条数は任意に設定できるが、例えば、条数は４〜６程度にするのが好ましい。さらに、このネジ金具９のリードやねじ幅も種々の範囲に設定可能であるが、螺着ための回転角が５０〜１５０度程度に、さらに好ましくは７０〜１１５度程度になるように設定するのが好ましい。このネジ金具９は上述の第２雌ねじ部に螺着するが、所定の回転角に設定するのが操作性の観点より好ましい。即ち、多条ねじにすることにより、必要な強度を維持しつつ螺着のための回転角を小さくできる。通常のねじ（１条ねじ）の場合、噛み合うまで最大３６０度回転する必要がある。
【００２５】
塗料層１０は、挿入部６のねじ金具９の穂先側の周面に、例えば、ウレタン塗料を塗布することで形成されている。この塗料層１０は、尻栓４の径の変化しない部分の内径に凡そ合致する「がたつき」のない程度の外径となるように塗布形成すればよい。
グリップ部７は、挿入部６より大径且つ元竿１の外周面に合致するような径のパイプ状部材である。元竿１や挿入部６と同様に繊維強化樹脂等から構成してもよいが、別途金属素材などから構成してもよい。挿入部６の竿元側端部に挿入部６が穂先側から挿入された状態で接着等の手法によってグリップ部７は連結されている。グリップ部７は挿入部６が完全に挿入された状態でも、グリップ部７の穂先側端部に挿入部６が部分的に挿入された状態でもよい。
【００２６】
（元竿１と延伸竿２との連結固定について）
この釣竿の延伸竿２は元竿１内に収納した状態（収納状態：図２，図５）と、元竿１内から手元側に引き出した状態（延伸状態：図３）との何れにあっても元竿１に連結固定可能である。釣りを行っている最中において、延伸竿２を元竿１から手元側に引き出して延伸状態とし、若しくは、延伸竿２を元竿１内に押し込んで収納状態とし、状況に応じて釣竿全体の長さを調整して釣りを行う。
【００２７】
図２及び図５に示すように、収納状態にあっては、元竿１内に竿元側から延伸竿２が挿入され、延伸竿２の挿入部６の穂先側端部の嵌合雄部６ａが先細りテーパの中で一部分径の変化していない一部分Ｘに至り、ここで嵌合雄部６ａが径の変化しない部分Ｘに嵌着する。
このような収納状態にあっては、さらに、仮止め状態と本止め状態の何れも可能である。即ち、嵌合雄部６ａを径の変化しない部分Ｘに嵌着させると、挿入部６の竿元側端部の塗料層１０も尻栓４の内周面に当接する。この状態でも十分に元竿１と収納竿２とは相互に連結固定されている（仮止め状態）。しかし、元竿１と延伸竿２とをさらに完全に連結固定するために、元竿１と延伸竿２とを相互に周方向に回動させて、尻栓４の第２雌ねじ部分とねじ金具９とを螺着させることもできる（本止め状態）。このような本止め状態にあっては、２点で相互に嵌着するのでがたつきの程度も小さくなる。また、釣りを終えて釣竿を完全に仕舞った際にも、不用意に延伸竿２が元竿１から飛び出してしまうこともない。
【００２８】
一方、図３に示すように、延伸状態にあっては、元竿１内から竿元側に延伸竿２が引き出されると、延伸竿２の挿入部６の穂先側端部の嵌合雄部６ａは元竿１の竿元側端部に至りパイプ状の尻栓４の内周面の逆テーパ部分に嵌着する。
以上のように、この釣竿では、収納状態において、元竿１の軸方向中央付近内周面で延伸竿２の嵌合雄部６ａを嵌着させ、また、延伸状態においても、元竿１の竿元側の内部で延伸竿２の嵌合雄部６ａを嵌合させる。よって、釣竿を川の中等で使用している際に延伸竿２を元竿１から出し入れしても、相互の嵌合部分にゴミや水などが付着し難く、嵌合力の低下や固着なども生じにくい。
【００２９】
［他の実施形態］
上記実施形態に代えて、以下のような変形例も提案できる。
（ａ）図６に示すように、この元竿１にあっては、軸方向中央付近の内周面の径の変化しない部分を別部材から構成する。即ち、元竿１を先細りテーパの施された筒状体として、元竿１自体には径の変化しない部分を形成しない。これに代えて、別途所定の径の変化しない部分を内周面に施したパイプ状の金属又は合成樹脂製の部材２０を配置する。この部材は、元竿１の竿元側から挿入して所定の位置で接着材等により固定する。
（ｂ）図７に示すように、この延伸竿２にあっては、延伸竿２自体に嵌合雄部２を形成しない。延伸竿２の穂先側に連結されるゴムカバー３０を嵌合雄部として用いる。即ち、延伸竿２の穂先側に連結するゴムカバー３０の外周面を延伸竿２の穂先側に比して太径に設定し穂先側に延伸する。そして、このゴムカバー３０の外周面を元竿１の内周面等に嵌着させる。
【００３０】
【発明の効果】
本発明に係る釣竿では、元竿と延伸竿との間で釣竿全体の長さを変化させることができ、且つ、当該竿同士の十分な嵌着力を長期にわたって維持できる。

BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod used for fishing. More specifically, the present invention relates to a fishing rod that has an extending rod that is connected to the rod side of the rod so that it can be inserted and removed freely and can easily adjust the length of the entire rod.
[0002]
[Prior art]
In general, a fishing rod is formed as a single fishing rod by connecting a plurality of rods by a swinging type or a cascade type. Various types of fishing rods are provided with various functions in accordance with the application. For example, in the rods for fishing rods and mountain stream rods, in order to make it easier to capture the fish caught on the device, a function is provided that allows the fishing rod to be quickly changed during fishing operations. Yes.
[0003]
For example, in a certain type of conventional kite, a stretched kite is separately connected to the base side end portion of the model kite. This stretcher can be connected and fixed to the main bar in either the state stored in the main bar (stored state) or the state pulled out from the front of the main bar toward the hand side (extended state). Then, during the fishing operation, the angler performs fishing by adjusting the length of the entire fishing rod and taking out the extending rod depending on the situation (see, for example, Patent Document 1). Specifically, in the conventional fishing rod with adjustable length of the fishing rod as described above, in the stored state, the inner peripheral surface of the heel side of the heel and the heel side of the extended heel It has a structure that fits with the peripheral surface.
[0004]
[Patent Document 1]
Utility Model Registration No. 3022411 (FIGS. 2 and 3)
[0005]
[Problems to be solved by the invention]
However, as described above, in this type of fishing rod, during the fishing operation (especially in the river in the case of a rod), the stretched material is put into and out of the main rod depending on the situation. And dust, pebbles, water, etc. are likely to adhere to the base side of the stretched ridge. For this reason, a sufficient fitting force cannot be secured during operation, or conversely, sticking or the like tends to occur. Furthermore, if it is used repeatedly, the fitting force tends to decrease.
[0006]
The subject of this invention is providing the fishing rod which can change the length of the whole fishing rod between a main rod and an extending rod, and can maintain sufficient fitting force of the said rods.
[0007]
[Means for Solving the Problems]
The fishing rod according to the first aspect of the present invention is a fishing rod that is formed by sequentially connecting a plurality of rod-shaped rods, and is connected to the main rod and the main rod side of the main rod so as to freely enter and exit the main rod. It is provided with an extension rod that can be fixed to the main bar in either the stored state housed inside or the extended state pulled out to the base side of the main bar.
[0008]
The main shaft is a pipe-shaped member that is detachably connected to the base side of the main body portion and is inserted from the base side end portion of the main shaft, and the tubular main body portion that is tapered as a whole. It has a butt plug having a reverse taper portion on its inner peripheral surface.
In the main shaft, a portion where the diameter does not change is formed on the inner peripheral surface near the center in the axial direction of the main body.
On the other hand, the extension rod has an insertion portion formed with a fitting male portion formed on the outer peripheral surface of the tip side end portion having a diameter larger than that of the other portion where the diameter does not change, and a base portion of the insertion portion. And a grip portion connected to the side. And
In the retracted state, the extension rod can be inserted into the base rod from the base side, the portion of the inner peripheral surface in the vicinity of the center in the axial direction of the main body portion where the diameter does not change, and the fitting male portion of the extension rod Can be fitted,
In the extended state, the bottom plug can be fitted to the fitting male part.
[0009]
The fishing rod can be connected and fixed to the main rod regardless of whether it is stored in the main rod (stored state) or pulled out from the main rod to the hand side (extended state). During fishing, draw the extended rod from the main rod to the hand side to be in the extended state, or push the extended rod into the main rod to be in the stowed state, and adjust the length of the whole fishing rod according to the situation And do fishing. Specifically, in each state, the base rod and the stretched rod are connected and fixed in the following manner.
[0010]
First, when in the stowed state, the extended rod is inserted into the main rod from the rod side, and the fitting male part at the end side of the extended rod is the inner peripheral surface near the center in the axial direction of the main body of the main rod. Fit into. On the other hand, in the stretched state, when the stretched cocoon is pulled out from the inside of the heel to the heel side, the fitting male part of the end side of the stretched heel reaches the heel side end of the heel and is in the shape of a pipe. Fits on the inner peripheral surface of the butt plug.
[0011]
In this way, in the retracted state, the mating male part of the elongated rod is fitted on the inner peripheral surface near the center of the shaft in the axial direction, and also in the elongated state, Fit the mating male part. Therefore, dust and water are difficult to adhere to the fitting portion, and the fitting force is less likely to be reduced or fixed.
The fishing rod of the invention 2 is the fishing rod of the invention 1, and the butt plug has a reverse taper portion whose diameter decreases toward the base side on the inner peripheral surface. Moreover, the fitting male part of the insertion part of the extending hook has a part where the diameter does not change and a reverse taper part which is continuous with the base side and the diameter becomes smaller toward the base side. Then, in the stored state, the constant portion of the diameter of the part and Hamagoyu portion unchanged in diameter of the body portion of the base rod are possible fitted, the In the stretching condition, the butt plug The reverse taper portion and the reverse taper portion of the fitting male portion can be fitted.
[0012]
In this fishing rod, the fitting state according to each state is produced by making the fitting part different in what is called a stowed state and a stretched state. Moreover, even if the detachment is repeated, the degree of deterioration of the mutual fitting portion is reduced.
Here, the portion where the diameter does not change is a portion where the diameter does not change within a certain range in the axial direction or a portion where the diameter changes only very subtly. The reverse taper portion means a taper that decreases in diameter toward the hand side.
[0013]
The fishing rod of the invention 3 is the fishing rod of the invention 1 or 2, and the bottom plug of the main rod has a female thread portion on the inner peripheral surface of the rod side end portion. Moreover, the extending | stretching rod has the external thread part which can be screwed to the internal thread part of the collar part side edge part outer peripheral surface of an insertion part.
In this fishing rod, when the mating male part of the extended rod is fitted in the portion where the diameter of the original rod does not change, and the male rod and the elongated rod are to be completely fixed, the male screw portion is used as the female screw portion. Screw it on.
[0014]
The fishing rod of the invention 4 is the fishing rod of the invention 3, wherein the extended rod has a coating layer on the outer peripheral surface of the base portion of the insertion portion, and the coating layer is temporarily attached to the inner peripheral surface of the bottom plug of the main rod. To do.
In this fishing rod, when the insertion portion of the insertion rod is inserted from the flange side end portion of the base rod, first, the coating layer is temporarily fitted to the inner peripheral surface of the bottom plug. Thereafter, if necessary, the internal thread portion and the external thread portion are screwed together to obtain a final stop state. During fishing, the temporarily stopped state and the fully stopped state are properly used according to the situation. Further, in the fully-fastened state, the portion to be fitted becomes two points, so that rattling is unlikely to occur.
[0015]
The fishing rod of the invention 4 is the fishing rod of the invention 2 or 3, wherein the male screw portion and the female screw portion are multi-threaded screws.
In this fishing rod, in particular, a multi-threaded screw is used for the male screw portion and the female screw portion, and the male screw portion and the female screw portion can be screwed together by slightly rotating the main rod and the extending rod. . Moreover, when fishing rods are completely stored after fishing, the rod bodies can be sufficiently fixed with the multi-threaded screws, so that the extended rod does not inadvertently jump out of the main rod.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
The fishing rod adopting the first embodiment of the present invention is a fishing rod used for fishing rods and the like, and as shown in FIG. It has 竿 2. In addition, a plurality of rod bodies (a middle rod, a tip rod, etc.) are also connected to the tip side of the base rod 1 (not shown). Each of these cases is formed by firing a prepreg material obtained by impregnating a reinforcing resin such as carbon fiber with a synthetic resin.
[0017]
Each housing on the tip side from the main rod 1 is connected in a so-called swing-out form, and can be inserted into and removed from the housing on the head side sequentially from the head-side housing. The outer peripheral surface of the heel-side end of each of the pods located on the tip side can be fixed to each other by being fitted to the inner peripheral surface of the stylus side adjacent to the heel side. A fishing line locking tool is arranged at the end of the tip end of the tip end located on the end side. In addition, the main rod 1 and the extended rod 2 located on the side of the flange can be connected and fixed to each other regardless of the extended state or the stored state, as will be described later. .
[0018]
(About Genroku 1)
The main shaft 1 is a cylindrical body that is tapered so that the diameter of the tip is smaller toward the tip side as a whole. However, the inner peripheral surface near the center in the axial direction is provided with a portion where the diameter does not change partially (see FIG. 2: X range). That is, the heel 1 is tapered such that the inner diameter is gradually increased from the tip side toward the heel side (see range A). In some of them, the inner diameter does not change partially (X range). And in the part which continues to the base side of X range, a steep taper part is formed so that it may correspond to the taper of A range again (B range). The part where the diameter does not change is fitted in the end side end portion of the extending rod 2 to be described later in the stored state (see FIG. 2).
[0019]
As shown in FIG. 3, a butt ring 3 and a butt plug 4 are detachably attached to a heel side end portion of the ledge 1.
The bottom ring 3 is a cylindrical member made of metal (aluminum alloy), and the inner peripheral surface of the heel side end portion is formed with a thread groove to be a first female screw portion. A part of the outer peripheral surface of the heel side end of the heel 1 is cut and recessed from the rim side edge, and the butt ring 3 covers the recessed part so that the butt ring 3 covers the recessed part. It is attached to the part where the tip of the head is recessed. At this time, the outer diameter of the buttocks ring 3 is preferably set so as to match the outer diameter of the main shaft 1.
[0020]
The bottom plug 4 is a cylindrical member made of hard synthetic resin. The tip side is an insertion portion whose outer diameter is reduced by one step, and the heel side end portion is a head portion that is increased by one step so that the outer diameter matches the outer diameter of the above-described buttocks ring 3. . The insertion portion is a portion that is inserted into the interior of the base rod 1 from the base side. And an outer peripheral surface is a surface where a diameter does not change, and an inner peripheral surface is comprised from the reverse taper part which becomes smaller diameter as the base side, and the part which does not change the diameter which continues to the base side. The reverse taper portion of the inner peripheral surface of the bottom plug 4 is fitted to the end portion on the tip side of the extending rod 2 to be described later in the extended state, and the portion where the diameter does not change is fitted to the extending rod in the inserted state (FIG. 3). reference). Further, in the vicinity of the level difference between the insertion portion and the head portion at the base end portion, a thread groove that is screwed into the first female screw portion of the above-described buttocks ring 3 is formed to form a first male screw portion. In addition, on the inner peripheral surface (inner periphery of the head portion) of the base end portion of the butt plug 4, the inner diameter is increased by one step to form a screw groove to form a second female screw portion. The thread groove of the second female thread portion will be described later.
[0021]
In this way, the bottom plug 4 is detachably attached to the main shaft 1 via the bottom ring 3 by screwing the first male thread portion to the first female thread portion of the bottom ring 3.
(About stretched ridge 2)
As shown in FIG. 4, the extending rod 2 is an insertion portion 6 that is inserted into the inside from the base side of the base rod 1 and a large-diameter pipe-like member that is connected to the base side of the insertion portion 6. It consists of a grip part 7.
[0022]
The insertion portion 6 is an outer diameter cylindrical body that can be inserted into the main shaft 1. The insertion portion 6 has a reverse taper that does not change in diameter or has a smaller diameter toward the base side. However, the outer peripheral surface of the end on the tip side is a part where the outer diameter does not change in a certain range in the axial direction and the diameter is larger than the other part (this part is painted), and its base side And a reverse taper portion having a diameter smaller toward the base side. This is the fitting male portion 6a (see FIGS. 2 and 3). The outer diameter of the fitting male portion 6a is such that the portion where the diameter does not change matches the portion X where the diameter of the main shaft 1 does not change, and the reverse taper portion matches the inner diameter of the reverse taper of the bottom plug 4.
[0023]
The insertion portion 6 includes a rubber cover 8 disposed at the tip side end portion and a screw fitting 9 attached to the outer peripheral surface of the heel side end portion. A paint layer 10 is formed on the peripheral surface adjacent to the tip side of the screw fitting 9.
The rubber cover 8 is a cylindrical member formed of a well-known elastic rubber and having a hollow passing through in the axial direction. A part of the outer peripheral surface of the heel side is shaved, and this is inserted into the end of the tip of the insertion portion 6 and fixed with an adhesive or the like. The inner diameter of the rubber cover 8 on the tip side is tapered so as to increase in diameter toward the end portion on the tip side. In addition, a “split” is also formed in the axial direction from the end on the tip side. The rubber cover 8 is used to smoothly guide the inner hook or the like into the insertion portion when the inner hook or the like connected in a swinging manner to the tip side of the original hammer 1 is accommodated in the main fence 1.
[0024]
The screw fitting 9 is a ring-shaped member that is attached to the outer peripheral surface of the base end portion of the insertion portion 6 (adjacent to the tip side of the grip portion 7). The insertion portion 6 is attached by a known method such as adhesion or screwing. Multiple thread grooves are formed on the outer peripheral surface of the screw fitting 9. The thread width and the number of threads of the multi-threaded screw can be arbitrarily set. For example, the number of threads is preferably about 4 to 6. Furthermore, the lead and the screw width of the screw fitting 9 can be set in various ranges, but are set so that the rotation angle for screwing is about 50 to 150 degrees, more preferably about 70 to 115 degrees. Is preferred. The screw metal fitting 9 is screwed into the second female screw portion described above, but it is preferable from the viewpoint of operability to set a predetermined rotation angle. That is, by using a multi-thread screw, the rotation angle for screwing can be reduced while maintaining the required strength. In the case of a normal screw (single thread), it is necessary to rotate up to 360 degrees until they are engaged.
[0025]
The paint layer 10 is formed, for example, by applying urethane paint to the peripheral surface on the tip side of the screw fitting 9 of the insertion portion 6. The coating layer 10 may be applied and formed so as to have an outer diameter that does not have “rattle” that roughly matches the inner diameter of the portion of the bottom plug 4 where the diameter does not change.
The grip portion 7 is a pipe-shaped member having a diameter larger than that of the insertion portion 6 and a diameter that matches the outer peripheral surface of the main shaft 1. Although it may be composed of a fiber reinforced resin or the like, similar to the main fence 1 or the insertion portion 6, it may be composed of a metal material or the like separately. The grip part 7 is connected to the base side end of the insertion part 6 by a technique such as adhesion in a state where the insertion part 6 is inserted from the tip side. The grip portion 7 may be in a state in which the insertion portion 6 is completely inserted, or may be in a state in which the insertion portion 6 is partially inserted in the end portion on the tip side of the grip portion 7.
[0026]
(Regarding the connection and fixing of the former fence 1 and the extended fence 2)
The fishing rod extension rod 2 is stored in the main rod 1 (stored state: FIGS. 2 and 5) or pulled out from the main rod 1 to the hand side (extended state: FIG. 3). However, it can be connected and fixed to the main fence 1. During fishing, the extended rod 2 is pulled out from the main rod 1 to the extended state, or the extended rod 2 is pushed into the main rod 1 to be in the stowed state. Adjust the length for fishing.
[0027]
As shown in FIGS. 2 and 5, in the housed state, the extension rod 2 is inserted from the base side into the base rod 1, and the fitting male portion at the end of the tip side of the insertion portion 6 of the extension rod 2 6a reaches a portion X where the diameter does not change in the taper taper, and the fitting male portion 6a is fitted to the portion X where the diameter does not change.
In such a storage state, both a temporarily fixed state and a fully fixed state are possible. That is, when the fitting male portion 6 a is fitted to the portion X whose diameter does not change, the paint layer 10 at the base side end portion of the insertion portion 6 also comes into contact with the inner peripheral surface of the bottom plug 4. Even in this state, the main rod 1 and the storage rod 2 are sufficiently connected and fixed to each other (temporarily fixed state). However, in order to more completely connect and fix the main rod 1 and the extended rod 2, the main rod 1 and the extended rod 2 are rotated in the circumferential direction so that the second female screw portion of the bottom plug 4 and the screw fitting are rotated. 9 can also be screwed together (full stop state). In such a fixed state, since the two parts are fitted to each other, the degree of rattling is reduced. Further, when the fishing rod is completely finished after the fishing, the extended rod 2 does not inadvertently jump out of the main rod 1.
[0028]
On the other hand, as shown in FIG. 3, in the stretched state, when the stretched rod 2 is pulled out from the base rod 1 to the base side, the fitting male part at the tip side end portion of the insertion portion 6 of the stretched rod 2 6a reaches the base side end of the base rod 1 and is fitted to the reverse taper portion of the inner peripheral surface of the pipe-shaped bottom plug 4.
As described above, in this fishing rod, in the housed state, the fitting male portion 6a of the extending rod 2 is fitted on the inner peripheral surface near the center in the axial direction of the main rod 1, and also in the extended state, The fitting male part 6a of the extension rod 2 is fitted inside the base side. Therefore, even when the fishing rod is used in a river or the like, even if the extended rod 2 is taken in and out of the main rod 1, dust and water are difficult to adhere to each other, and the fitting force is reduced and fixed. Hard to occur.
[0029]
[Other Embodiments]
Instead of the above-described embodiment, the following modifications can be proposed.
(A) As shown in FIG. 6, in the main shaft 1, a portion where the diameter of the inner peripheral surface in the vicinity of the center in the axial direction does not change is formed from another member. That is, the base rod 1 is formed as a tapered and tapered cylindrical body, and the base rod 1 itself is not formed with a portion whose diameter does not change. Instead of this, a pipe-shaped metal or synthetic resin member 20 in which a part having a predetermined diameter that does not change is provided on the inner peripheral surface is disposed. This member is inserted from the base side of the base rod 1 and fixed with an adhesive or the like at a predetermined position.
(B) As shown in FIG. 7, in this extending rod 2, the fitting male part 2 is not formed in the extending rod 2 itself. A rubber cover 30 connected to the tip side of the stretcher 2 is used as a fitting male part. That is, the outer peripheral surface of the rubber cover 30 connected to the tip side of the extending rod 2 is set to have a larger diameter than the tip side of the extending rod 2 and is extended to the tip side. Then, the outer peripheral surface of the rubber cover 30 is fitted to the inner peripheral surface of the main shaft 1 or the like.
