【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。
【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、仕掛けに係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）。
【０００４】

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】
図６において示すように、上述のような従来の釣竿にあっては、延伸状態において延伸竿１０１の穂先側端部を元竿１００の竿元側端部内周面に嵌合させるために、元竿の内径より一段小径のパイプ状の嵌合部材１０２を配置している。このため、延伸状態において、延伸竿１０１の周面と嵌合部材１０２との段差（ΔＸ）が大きくなってしまう。このような段差は、元竿と挿入竿との間にゴミなどの進入を招き易く、また、外観も損なう。
【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、元竿と延伸竿との間の大きな段差を解消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前記元竿に固定可能な延伸竿とを備えている。
【０００８】
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るパイプ状部材であり、本体部の内周面には、軸方向中央付近に、部分的に、内径が変化しない部分が設けられ、本体部の内周面は全体として竿元側ほど小径化する逆テーパ面となっている栓とを有している。一方、延伸竿は、穂先側端部外周面に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、挿入部の嵌合雄部が元竿の本体部の軸方向中央付近の内径が変化しない内周面及び栓の内周面に嵌着可能である、釣竿。
【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ると、元竿の先細りテーパとの関係で、延伸竿の嵌合雄部は元竿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から栓内に至り、その内周面に嵌着する。この場合、栓は元竿内に位置して嵌合面を提供するのではなく、元竿の竿元側に突出して嵌合面を提供しており、相対的に元竿と延伸竿との段差が小さくなる。また、栓を取り外せば延伸竿が元竿から容易に分離する。そして、長期の使用により摩耗等が生じた場合には栓を容易に交換でき、長期にわたって嵌着力を維持することもできる。
【００１１】
なお、ここで径の変化しない部分というのは、軸方向一定範囲において径の変化しない部分若しくは極めて緩やかな径変化に留まるようなものをいう。
発明２の釣竿は、発明１の釣竿であって、栓は、その外周面が竿元側ほど小径化するテーパ面となっている。
元竿の竿元側に位置する栓の内外周面をテーパ面として、外観上も元竿と延伸竿との段差が可及的に小さくなる。
【００１２】
発明３の釣竿は、発明１又は２の釣竿であって、元竿の穂先側に振出形式で連結される元上竿をさらに備える。そして、この元上竿は穂先側端部に脱着自在に装着され外径方向に張り出したフランジ部材を有している。
元竿の竿元側に延伸竿を延伸させた状態で、振出形式に元竿の穂先側に連結される元上竿を元竿内に収納すると、元上竿が元竿からさらに延伸竿内にまで至ってしまう恐れがある。即ち、元上竿が元竿内に完全に入り込んでしまい、取り出すことが困難となる恐れがある。この釣竿では、元上竿の穂先側のフランジ部材が元竿の穂先側端面に当接して、元上竿が元竿内に入り込んでしまうことを防止する。
【００１３】
発明４の釣竿は、発明３の釣竿であって、元上竿は竿元側端部に脱着自在に装着された底栓を有し、この底栓は元上竿の竿元側を閉塞している。
元上竿の穂先側にさらに振出形式で連結される他の竿体がある場合、これらの他の竿体を元上竿内に振出形式で収納しても、この底栓によって、これら他の竿体が元上竿の竿元側に入り込んでしまうことはない。
【００１４】
【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の穂先側は元上竿３，及び中竿４等が連結されている。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。
【００１５】
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。最も穂先側に位置する穂先竿（図示せず）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。
【００１６】
（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。元竿１の軸方向中央付近の内周面に於いては、部分的に軸方向においてその内径が変化しない部分が設けられている（図３：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。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、通常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ている。この径の変化しない部分Ｘ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３参照）。
【００１７】
図２に示すように、この元竿１の竿元側端部には栓５が脱着自在に装着されている。元竿１の竿元側端部外周面にはねじ溝が形成されて雄ねじ部分が形成されている。
栓５は竿体を構成するものと同種のプリプレグ素材（軽い、通常の合わせと同様の技術を使える）や硬質合成樹脂からなるパイプ状の部材である。穂先側は内径が一段大径化しており、元竿１の竿元側端部を内包しつつ上述の元竿１の雄ねじ部分に螺着する雌ねじ部分となっている。一方、栓５の竿元側の内周面は、元竿１の竿元側端部内周面に連続して、穂先側が径の変化しない部分となっており、その竿元側が竿元側ほど小径化する逆テーパ部分となっている。この実施形態では、栓５の内周面を径の変化しないものと逆テーパ面とを組み合わせた例を示しているが、単なる逆テーパ面に留めることも可能である。この栓５の竿元側の内周面（逆テーパ面）が、後述する延伸竿２の穂先側端部と延伸状態に於いて嵌着する（図２参照）。また、栓５の外周面は穂先側端部においては元竿１の外周面にあわせてあり、竿元側に至るに徐々に小径化するような逆テーパ面とするのが好ましい。
【００１８】
（延伸竿２について）
図１〜３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。
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、テーパ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テーパを施しておく。この穂先側端部の外周面は、軸方向の一定範囲で外径が他の部分より大径化されており、ここが嵌合雄部６ａとなっている（図２，３参照）。嵌合雄部６ａは他の部分より大径化され且つ軸方向に於いて径が変化しない穂先側部分と、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からなる。この嵌合雄部６ａの径の変化しない部分の外径は上述の元竿１の径の変化しない部分Ｘにあわせて設定されており、逆テーパ部分の径は栓５の逆テーパ部分の内径にあわせて設定されている。
【００１９】
また、この挿入部６は、穂先側端部に配置されるゴムカバー８を有している。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元上竿２などを元竿１内に収納する際に、円滑に元上竿３を挿入部６内に導くためのものである。
【００２０】
一方、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が穂先側から挿入された状態で螺着など周知の手法で脱着自在にグリップ部７は挿入部６の竿元側端部に連結されている。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。また、グリップ部７を挿入部６に接着などで固定してしまってもよい。
【００２１】
（元上竿３について）
図４及び図５に示すように、元上竿３も先細りテーパの施された筒状体である。上述のように、元竿１の穂先側に振出形式で連結されている。
元上竿３の穂先側端部には脱着自在に口栓１０が装着され、また、竿元側端部にも脱着自在に底栓１１が装着されている。
【００２２】
元上竿３の穂先側端部外周面にはねじ溝が形成されボルト部分となっている。ここに口栓１０が脱着自在に螺着している。口栓１０は、合成樹脂（例えば、弾性ゴム）や軽合金（アルミニウムなど）から構成され軸方向に貫通する中空の略パイプ状の部材である。この口栓１０の中空を中竿４等が挿通する。口栓１０は内周面に上述の元上竿３に螺着するナット部分を有し、元上竿３の穂先側端部を内包するように元上竿３に装着されている。この口栓１０の外径は元竿１の穂先側端部の内径より大きく設定される。即ち、口栓１０は元上竿３の穂先側において外方向に張り出し、元上竿３が元竿１内に入り込んでしまうのを抑えている。このような口栓１０を装着しておくことで、例えば、釣りを終えて釣竿を完全に仕舞った際にも、不用意に元上竿３が元竿１内に入り込んでしまい持ち運び時に不便が生じることもない。
【００２３】
元上竿３の竿元側端部内周面にもねじ溝が直接形成されておりナット部分となっている。ここに底栓１１が脱着自在に螺着している。底栓１１も弾性ゴム若しくは軽金属等からなる栓部材である。穂先側の外周面が元上竿３の竿元側端部に螺着するボルト部分となっており、ボルト部分の竿元側が元上竿３の外径に合致するような頭部分となっている。底栓１１は軽量化のために中空化してもよく、軸方向に貫通する空気穴などを形成しても良い。図５に於いては、底栓１１の穂先側を閉塞するゴム板を配置したものを例示している。この底栓１１は、中竿４などが元上竿３を挿通して竿元側に飛び出すことを抑えるための栓として機能する。
【００２４】
（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３）と、元竿１内から手元側に引き出した状態（延伸状態：図２）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。
【００２５】
図３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の挿入部６が挿入されると、延伸竿２の挿入部６の嵌合雄部６ａの径の変化しない部分が元竿１の軸方向中央付近に形成される径の変化しない部分Ｘに嵌着する。このように、収納状態において元竿１の軸方向中央付近の内周面で延伸竿と嵌着させることで、がたつきが無くまた使用中に元竿が落ちない。嵌着面にゴミなどが溜まり難くなる。
【００２６】
一方、図２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の穂先側端部の嵌合雄部６ａは元竿１の竿元側から栓５内に至り、嵌合雄部６ａの逆テーパ部分が栓５の内周面（逆テーパ部分）に嵌着する。この場合、栓５は元竿１内に位置して嵌合面を提供するのではなく、元竿１の竿元側に突出して嵌合面を提供しており、相対的に元竿１と延伸竿２の挿入部６の外周面との段差が小さくなる。また、栓５の外径も竿元側ほど小径化するようなテーパ面としており、外観上も段差が目立たない。
【００２７】
また、栓５を元竿１から取り外せば延伸竿２が元竿１から容易に分離する。長期の使用により栓５に摩耗等が生じた場合には、グリップ部７を挿入部６から取り外して、栓５を挿入部から取り外して容易に交換でき、長期にわたって嵌着力を維持することもできる。
［他の実施形態］
（ａ）上述の栓５の内周面（嵌合面）に、エポキシ樹脂などから構成されるフィルムを貼り合わせてもよい。栓５と嵌合雄部６ａとの嵌着時の相互の摩耗を抑えることができる。
（ｂ）また、栓５の竿元側端部から軸方向に必要に応じて「割り」を入れてもよい。
【００２８】
【発明の効果】
本発明に係る釣竿によれば、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、元竿と延伸竿との間の大きな段差を解消できる。
さらに、長期の使用によって元竿と延伸竿との嵌合力が低下するに至っても、容易にその嵌合力を回復できる。

BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod used for fishing.
[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 a total number of fishing rods such as a rod for fishing rods and mountain stream rods, a function is provided that allows the fishing rod to be quickly changed during fishing operations in order to make it easier to capture the fish associated with the device. ing.
[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).
[0004]
[Patent Document 1]
Utility Model Registration No. 3022411 (FIGS. 2 and 3)
[0005]
[Problems to be solved by the invention]
As shown in FIG. 6, in the conventional fishing rod as described above, in order to fit the tip side end portion of the extended rod 101 to the inner peripheral surface of the heel side end portion of the main rod 100 in the extended state, A pipe-shaped fitting member 102 having a diameter one step smaller than the inner diameter of the collar is disposed. For this reason, in the extended state, the step (ΔX) between the peripheral surface of the extending rod 101 and the fitting member 102 becomes large. Such a step is liable to cause entry of dust or the like between the main rod and the insertion rod, and also deteriorates the appearance.
[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 eliminate the big level difference between a main rod and an extending rod. .
[0007]
[Means for Solving the Problems]
The fishing rod according to the first aspect of the present invention is a fishing rod formed by sequentially connecting a plurality of cylindrical 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. And a stretched bar that can be fixed to the base bar in either the stored state stored in the base bar or the extended state pulled out to the base side of the main bar.
[0008]
The main shaft is a tubular main body portion that is tapered as a whole, and a pipe-shaped member that is detachably connected to the base side of the main body portion. In the vicinity, a portion where the inner diameter does not change is provided in part, and the inner peripheral surface of the main body portion has a plug having a reverse tapered surface whose diameter decreases toward the base as a whole. On the other hand, the extension rod is connected to the insertion side where the fitting male part formed larger in diameter than the other part is formed on the outer peripheral surface of the tip end side and inserted into and out of the main part, and the base side of the insertion part. And a grip portion. And the fishing rod in which the fitting male part of the insertion part can be fitted to the inner peripheral surface where the inner diameter in the vicinity of the axial center of the main body part of the main rod does not change and the inner peripheral surface of the stopper.
[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, in the stowed state, when the extended rod is inserted into the main shaft from the base side, the male part of the extended rod is near the center of the main shaft in the axial direction due to the taper taper of the main rod. Fits on the inner peripheral surface. On the other hand, in the stretched state, when the stretched cocoon is pulled out from the heel to the heel side, the fitting male part of the end side of the stretched heel reaches the stopper from the heel side of the heel. Fits on the inner surface. In this case, the stopper is not located in the main bar to provide the fitting surface, but protrudes toward the side of the main bar to provide the fitting surface. The step becomes smaller. Moreover, if the stopper is removed, the stretched wrinkles are easily separated from the main bar. And when abrasion etc. arise by long-term use, a stopper can be replaced | exchanged easily and a fitting force can also be maintained over a long term.
[0011]
Here, the portion where the diameter does not change refers to a portion where the diameter does not change within a certain range in the axial direction, or a portion where only a very gradual change in diameter occurs.
The fishing rod of the invention 2 is the fishing rod of the invention 1, and the stopper has a tapered surface whose outer peripheral surface is reduced in diameter toward the base side.
By using the inner and outer peripheral surfaces of the plug located on the base side of the main shaft as a tapered surface, the difference in level between the main shaft and the extended bar is as small as possible.
[0012]
The fishing rod of the invention 3 is the fishing rod of the invention 1 or 2, and further includes a former fishing rod connected in a swinging manner to the tip of the former rod. The former upper collar has a flange member that is detachably attached to the end portion on the tip side and protrudes in the outer diameter direction.
With the extension rod extended to the base side of the Marshal, when the former bowl connected to the head side of the Marshal in the swing type is stored in the Marshal, the Marshall pass further extends from the Marshal There is a risk of ending up. That is, there is a risk that the former bowl will completely enter the former bowl and be difficult to remove. In this fishing rod, the flange member on the tip side of the former upper rod is in contact with the end surface on the tip side of the former rod, thereby preventing the former upper rod from entering the former rod.
[0013]
The fishing rod of the invention 4 is the fishing rod of the invention 3, wherein the former upper rod has a bottom plug that is detachably attached to the end portion of the former rod, and this bottom plug closes the proximal portion of the former upper rod. ing.
If there are other rods connected in a swinging manner on the tip side of the former upper rod, even if these other rods are housed in the swinging manner in the upper rod, these other plugs can The body will not enter the base side of the Motogami Pass.
[0014]

In addition, the head side of the genius 1 is connected to the genital heel 3, the middle ridge 4, and the like. 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.
[0015]
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 of the tip rod (not shown) located closest to the tip. 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. .
[0016]
(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. On the inner peripheral surface in the vicinity of the center of the main shaft 1 in the axial direction, there is provided a portion where the inner diameter does not change in the axial direction (see FIG. 3: 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. 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, the steep taper part is formed so that it may agree | coincide with a normal taper again. This portion X where the diameter does not change fits in the retracted state with the end portion of the tip side of the extending rod 2 described later (see FIG. 3).
[0017]
As shown in FIG. 2, a stopper 5 is detachably attached to the end portion of the base side of the base 1. A thread groove is formed on the outer peripheral surface of the heel side end of the heel 1 to form a male thread portion.
The stopper 5 is a pipe-like member made of the same kind of prepreg material (light, which can be used in the same technique as that used in normal joining) or hard synthetic resin. The tip side has an inner diameter that is one step larger, and is an internal thread portion that is screwed into the external thread portion of the above-described base rod 1 while enclosing the base end portion of the base rod 1. On the other hand, the inner peripheral surface of the hook 5 on the heel side is continuous with the inner peripheral surface of the heel side of the heel 1, and the tip side is a portion where the diameter does not change. It is a reverse taper part with a reduced diameter. In this embodiment, an example is shown in which the inner peripheral surface of the plug 5 is combined with a reverse tapered surface that does not change in diameter, but it may be a simple reverse tapered surface. The inner peripheral surface (reverse taper surface) on the heel side of the stopper 5 is fitted in a stretched state with an end portion on the tip side of the extending heel 2 described later (see FIG. 2). Further, the outer peripheral surface of the stopper 5 is aligned with the outer peripheral surface of the heel 1 at the tip side end portion, and is preferably a reverse tapered surface that gradually decreases in diameter toward the heel side.

(About stretched ridge 2)
As shown in FIGS. 1 to 3, the extension rod 2 includes 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. The grip portion 7 is.
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 taper that does not change in taper or has a taper that decreases in diameter toward the base side. The outer peripheral surface of the end portion on the tip side has an outer diameter larger than that of other portions in a certain range in the axial direction, and this is a fitting male portion 6a (see FIGS. 2 and 3). The fitting male portion 6a is composed of a tip side portion whose diameter is larger than that of the other portion and whose diameter does not change in the axial direction, and a reverse taper portion whose diameter is continuously reduced toward the base side. . The outer diameter of the portion of the fitting male portion 6a where the diameter does not change is set in accordance with the portion X where the diameter of the main shaft 1 does not change, and the diameter of the reverse tapered portion is the inner diameter of the reverse tapered portion of the plug 5. It is set according to.
[0019]
Moreover, this insertion part 6 has the rubber cover 8 arrange | positioned at the tip side edge part. 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 smoothly guides the upper collar 3 into the insertion portion 6 when storing the upper collar 2 or the like connected in a swing-out manner on the tip side of the former collar 1 in the former collar 1. belongs to.
[0020]
On the other hand, the grip portion 7 is a pipe-like 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 portion 7 is connected to the base side end portion of the insertion portion 6 so as to be detachable by a known method such as screwing in a state where the insertion portion 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. Further, the grip portion 7 may be fixed to the insertion portion 6 by adhesion or the like.

As shown in FIGS. 4 and 5, the upper collar 3 is also a cylindrical body with a tapered taper. As mentioned above, it is connected to the tip side of the martial arts 1 in a swinging manner.
A mouth plug 10 is detachably attached to the tip side end of the former upper collar 3, and a bottom plug 11 is also detachably attached to the edge side of the collar.
[0022]
A screw groove is formed on the outer peripheral surface of the tip side end of the former upper collar 3 to form a bolt portion. Here, the plug 10 is screwed to be detachable. The plug 10 is a hollow, substantially pipe-shaped member that is made of a synthetic resin (for example, elastic rubber) or a light alloy (such as aluminum) and penetrates in the axial direction. The hollow 4 or the like is inserted through the hollow of the stopper 10. The spigot 10 has a nut portion that is screwed to the above-described former upper collar 3 on the inner peripheral surface, and is attached to the former upper collar 3 so as to enclose the end portion of the original upper collar 3. The outer diameter of the plug 10 is set to be larger than the inner diameter of the end portion on the tip side of the base 1. That is, the spigot 10 protrudes outward on the tip side of the former upper collar 3 to prevent the former upper collar 3 from entering the former collar 1. By attaching such a spigot 10, for example, even when fishing is finished and the fishing rod is completely completed, the original upper rod 3 will inadvertently enter into the main rod 1, causing inconvenience when carrying it. It does not occur.
[0023]
A thread groove is also directly formed on the inner peripheral surface of the base side end portion of the base upper rod 3 to form a nut portion. Here, the bottom plug 11 is screwed in a detachable manner. The bottom plug 11 is also a plug member made of elastic rubber or light metal. The outer peripheral surface on the tip side is a bolt portion that is screwed to the end portion on the heel side of the upper collar 3, and the head portion on which the heel side of the bolt portion matches the outer diameter of the upper collar 3. Yes. The bottom plug 11 may be hollow for weight reduction, or an air hole penetrating in the axial direction may be formed. In FIG. 5, the thing which has arrange | positioned the rubber plate which obstruct | occludes the tip side of the bottom plug 11 is illustrated. The bottom plug 11 functions as a plug for preventing the middle collar 4 or the like from passing through the upper collar 3 and jumping out to the collar side.

(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: FIG. 3) and pulled out from the main rod 1 to the hand side (extended state: FIG. 2). It can be connected and fixed to the flange 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.
[0025]
As shown in FIG. 3, in the stored state, when the insertion portion 6 of the extension rod 2 is inserted into the main rod 1 from the side of the flange, the fitting male portion 6 a of the insertion portion 6 of the extension rod 2 is inserted. The portion where the diameter does not change is fitted to the portion X where the diameter does not change, which is formed near the center of the main shaft 1 in the axial direction. In this way, in the housed state, by fitting with the elongated hook on the inner peripheral surface near the center in the axial direction of the main bar 1, there is no rattling and the main bar does not fall during use. Garbage is less likely to accumulate on the fitting surface.
[0026]
On the other hand, as shown in FIG. 2, in the stretched state, when the stretched heel 2 is pulled out from the interior of the main shaft 1 to the heel side, the fitting male portion 6 a at the end of the end of the stretched heel 2 becomes the front surface. 1 reaches the inside of the stopper 5, and the reverse tapered portion of the fitting male portion 6 a is fitted to the inner peripheral surface (reverse tapered portion) of the stopper 5. In this case, the plug 5 is not located in the main bar 1 to provide a fitting surface, but protrudes toward the bar side of the main bar 1 to provide a fitting surface. A level difference with the outer peripheral surface of the insertion part 6 of the extending | stretching rod 2 becomes small. Further, the outer diameter of the stopper 5 is a tapered surface that is reduced in diameter toward the base side, and the step is not conspicuous in appearance.
[0027]
Further, if the stopper 5 is removed from the main bar 1, the extended bar 2 is easily separated from the main bar 1. When wear or the like occurs in the plug 5 due to long-term use, the grip portion 7 can be removed from the insertion portion 6, the plug 5 can be removed from the insertion portion and easily replaced, and the fitting force can be maintained for a long time .
[Other Embodiments]
(A) A film made of an epoxy resin or the like may be bonded to the inner peripheral surface (fitting surface) of the plug 5 described above. Mutual wear at the time of fitting of the plug 5 and the fitting male portion 6a can be suppressed.
(B) Further, a “split” may be inserted in the axial direction from the base end of the stopper 5 as required.
[0028]
【The invention's effect】
According to the fishing rod according to the present invention, the entire length of the fishing rod can be changed between the main rod and the extended rod, and a large step between the original rod and the extended rod can be eliminated.
Furthermore, even if the fitting force between the base rod and the extending rod decreases due to long-term use, the fitting force can be easily recovered.
