Description

【０００１】
【発明の属する技術分野】
本発明は、振出形式で連結される竿体を相互に連結する際の連結構造に関する。詳しくは、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応用されるべき連結構造に関する。
【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。
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（特許文献１参照）。
【０００４】
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。
【０００５】
【特許文献１】
特開２０００−２６２１８９号公報（第１〜第２欄，図１，図２）
【０００６】
【発明が解決しようとする課題】
このような従来の釣竿では、元竿内に収納される元上竿の軸方向長さが、「延伸状態」と「収納状態」との長さの差（以下、「ズーム長さ」という）となって顕れる。即ち、元竿の軸方向長さがズーム長さを左右することになる。
一般に、元竿には、その穂先側の周面にリールを脱着自在に装着するためのリールシートを配置し、竿元側端部に釣人が把持するためのグリップ部分などを設けるので、その軸方向長さはある程度の長さに制限される。このように元竿の軸方向長さに規制がかかる故に、ズーム長さの設計の自由度も低下してしまう。
【０００７】
本発明の課題は、釣竿全体の長さを調整しつつ、円滑な釣り操作を可能とする釣竿にあって、そのズーム長さの自由度を高めるための竿体同士の連結構造を提供することにある。
【０００８】
【課題を解決するための手段】
発明１の連結構造は、竿元側端部に第１竿体保持手段を有する元竿と、元竿の穂先側に元竿内に出し入れ自在に連結され、竿元側端部に第２竿体保持手段を有する元上竿と、元上竿の穂先側に元上竿内に出し入れ自在に連結される元上々竿とを備える。
【０００９】
これら３つの竿体は、元上々竿，元上竿を順次元竿の穂先側に完全に引き出した延伸状態と、元上々竿，元竿を順次元竿の内部に完全に収納された収納状態との両状態において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。
まず、延伸状態においては、元竿の穂先側に元上竿が引き出され、元上竿の竿元側端部外周面と元竿の穂先側内周面とが嵌着する。さらに、元上々竿の竿元側端部外周面と元上竿の穂先側端部内取面とが嵌着する。そして、各々穂先側に位置する竿体の抜け止めが規制されると共に、相互の竿体が連結固定される。
【００１０】
一方、元上々竿が元上竿内に穂先側から収納され、元上々竿の竿元側端部が元上竿の竿元側端部に至ると、元上々竿の竿元側端部が元上竿の第２竿体保持手段に保持される。第２竿体保持手段に保持された元上々竿と元上竿とは、さらに、元竿内に穂先側から収納される。元上竿の竿元側端部が元竿の竿元側端部に至ると、元上竿の竿元側端部が元竿の第１竿体保持手段に保持される（収納状態）。
【００１１】
このようにして、この竿体の連結構造では、延伸状態，収納状態の何れにおいても相互に竿体を連結固定することが可能である。特に、元上竿を介在させることにより、元竿の軸方向長さにズーム長さが制約されず、自由度が高まる。
発明２の連結構造は、発明１の構造であって、第２竿体保持手段は元上竿の竿元側端部に脱着自在に装着された底栓である。この底栓は元上々竿の竿元側端部を収納して保持するために穂先側に開口し且つ元上々竿の竿元側への通過を規制するために竿元側が閉塞する収納窪みを有している。
【００１２】
元上々竿の元上竿への収納操作時にあっては、元上々竿の竿元側端部が底栓の開口からその収納窪みに収納されて保持される。収納窪みは竿元側には閉塞しており、元上々竿が底栓を通過して竿元側へ突出してしまうことはない。そして、元上々竿の収納に伴い、必ず、元上竿も元竿内に収納されることになる。
発明３の連結構造は、発明１または２の構造であって、第１竿体保持手段は元竿の竿元側端部に脱着自在に装着された尻栓である。この尻栓は元上竿の竿元側端部を収納して保持するために穂先側に開口する収納窪みを有している。
【００１３】
元上竿の元竿への収納操作時にあっては、元上竿の竿元側端部が尻栓の開口からその収納窪みに収納されて保持される。
発明４の連結構造は、発明１〜３の何れかの構造であり、元上竿の軸方向長さは元竿の軸方向長さより短く、元上々竿の軸方向長さは元竿の軸方向長さより長い。
【００１４】
このような竿体の軸方向長さを設定することで、収納状態に於いて元上竿が元竿内に完全に収納される。
【００１５】
【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１つの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Ｒ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，元上々竿３，第中竿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から形成される先細り筒状部材であって、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。
【００１６】
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。また、特に、元上々竿３〜元竿１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である。
【００１７】
また、元上々竿３の穂先側の周面には、リールＲからの釣糸Ｌを竿体内部に導入するための釣糸導入口７が形成されており、この釣糸導入口７を軸方向に覆うように釣糸導入ガイド８が装着されている。この釣糸導入口７から導入される釣糸Ｌは元上々竿３〜穂先竿５の内部の釣糸通路を挿通する。そして、穂先竿５の穂先側端部に装着されたトップガイド９から外部に導出されている。
【００１８】
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。
次に、元竿１〜元上々竿３の連結構造について、詳しく説明する。
図２〜図４に模式的に示すように、元竿１〜元上々竿３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。３本の竿体にあっては、元上々竿３が最も長い軸方向長さを有する。元上竿２が最も短く元竿１の軸方向長さより短い。例えば、ある一例を挙げれば、元竿１の軸方向長さを５０〜７０ｃｍとすると、元上竿２の軸方向長さは２０〜３０ｃｍ程度であり、元上々竿３は１００〜１４０ｃｍ程度の軸方向長さとなる。
【００１９】
この元竿１の竿元側端部には尻栓１０が脱着自在に装着される。この尻栓１０は嵌着式・螺着式等周知の手法で元竿１に装着する。螺着式にする際には、元竿１の竿元側端部内周面にねじ溝を形成してもよい。この尻栓１０はその穂先側の一部が元竿１の竿元側端部内に挿入される栓であり、その内部は穂先側に向かって開口する収納窪みとなっている。この収納窪み内に穂先側から元上竿２の竿元側端部が挿入され嵌着する（図２参照）。
【００２０】
このような尻栓１０は全体をゴム素材から構成することができる。もっとも、硬質合成樹脂などから尻栓１０を形成してもよい。また、収納窪みはその内周面に内径方向に突出する嵌着突起を複数形成しても良い。このような嵌着突起を設けることで、元上竿２との固着も防止できる。
上述のように、元竿１と元上竿２とはいわゆる振出形式で連結されており、元上竿２が元竿１の穂先側に引き出される際には、元竿１の穂先側端部内周面と元上竿２の竿元側端部外周面とが嵌着している（図３，４参照）。
【００２１】
元上竿２の竿元側端部には底栓１１が脱着自在に装着される。この底栓１１も尻栓１０と同様に嵌着式・螺着式等の周知の手法によって元上竿２に装着されている。螺着式にする際には、元上竿２の竿元側端部内周面にねじ溝を形成すれば足りる点も、尻栓１０と同様である。この底栓１１もその穂先側の一部が元上竿２の穂先側端部内に挿入される栓であり、その内部は、穂先側に向かって開口する収納窪みである。底栓１１の竿元側の端面は閉塞されており、収納窪み内に挿入されてくる元上々竿３が、底栓１１を挿通しないように配慮されている。
【００２２】
また、底栓１１は、図５に示すように、その竿元側端面に複数の通気孔１１ａを形成してもよい。このような通気孔１１ａ収納窪みから軸方向に貫通して形成することで、元上竿２への元上々竿３の収納・元上竿２〜元上々竿３の引き出し操作が円滑になる。また、この底栓１１についても、図５に示すように、収納窪みの内周面に嵌着突起１１ａを複数形成してもよい。
【００２３】
上述のように、元上竿２と元上々竿３とはいわゆる振出形式で連結されており、元上々竿３が元上竿２の穂先側に引き出される際には、元上竿２の穂先側端部内周面と元上々竿３の竿元側端部外周面とが嵌着している（図４参照）。
この元上々竿３の所定の周面には、脱着自在に補助リングＳを装着してもよい（図２参照）。即ち、元上々竿３が元竿１内に完全に収納された状態における元竿１の穂先側端部に生じる隙間を埋め、且つ、元上々竿３と元竿１との嵌着を安定させるために、元上々竿３の所定の軸方向位置の周面にゴム製のリングなどを装着してもよい。この補助リングＳは接着式若しくは螺合式等周知の手法で元上々竿３の周面に固定する。補助リングＳを脱着式にするのは、元上々竿３を元竿１の竿元側から取り外すためである。なお、さらに、元上々竿３の他の位置の周面（元上々竿３が元竿２内に完全に収納された際の元上竿２の穂先側端部に相当する位置）にも、同様の補助リングＳを装着し、若しくは、元上竿２の周面に肉盛を施しても良い。
【００２４】
このような元竿１，元上竿２，元上々竿３にあっては、元上々竿３及び元上竿２を元竿１の穂先側に完全に引き出した延伸状態（図４参照）と、元竿１の内部に元上竿２，元上々竿３を完全に収納した収納状態（図２参照）との両状態において相互に竿体を連結固定可能である。
即ち、図４に示すような延伸状態においては、元竿１の穂先側に順次引き出される元上竿２，元上々竿３が、それぞれの竿体の穂先側端部外周面・竿元側端部内周面で嵌着して抜け止めとなると共に、相互の竿体が連結固定される。
【００２５】
延伸状態から、元上々竿３を元上竿２内へ収納してゆくと、元上々竿３の竿元側端部が元上竿２の竿元側端部の底栓１１に至り、元上々竿３の竿元側端部が元上竿２の底栓１１の収納窪みに保持される（図３参照）。底栓１１の収納窪みは軸方向に貫通しておらず、元上々竿３をさらに竿元側に押し込むと、元上竿２と元上々竿３とが連なって元竿１内に挿入される。元上竿２の竿元側端部が元竿１の竿元側端部に至ると、元上竿２の竿元側端部が元竿の尻栓１０に保持される（収納状態）。
【００２６】
以上のように、元竿１〜元上々竿３においては、延伸状態，収納状態の何れにおいても相互に竿体を連結固定可能である。そして、釣竿全体の長さを調整しつつ、釣り状況に応じて釣りを行うことができるのである。元上竿２を介在させることで、元竿１の軸方向長さにズーム長さが制約されることもないので、元上竿２の軸方向長さを適宜設定することで、任意のズーム長さを演出し得る。
【００２７】
［他の実施形態］
図６に示すような尻栓２０と底栓２１とを採用し、元竿１と元上竿２との相互の嵌着を、尻栓２０と底栓２１とで行うこともできる。
この尻栓２０は、元竿１の竿元側に螺着するタイプのものである。上記実施形態と同様に穂先側に開口する収納窪み２０ａを内部に有する。一方、底栓２１も元上竿２の竿元側に螺着するタイプのものである。上記実施形態と同様に穂先側に開口する収納窪み２１ａを有するが、さらに、竿元側に突出する嵌合雄部２１ｂが設けられている。嵌合雄部２１ｂは竿元側に向かってやや先細りするテーパの施された柱状部分である、この嵌合雄部２１ｂが尻栓２０の収納窪み２０ａに収納されて嵌着される。
【００２８】
なお、底栓２１の嵌合雄部２１ｂと尻栓２０の収納窪み２０ａとの嵌着程度を調整するべく、上記実施形態と同様に、嵌合突起を収納窪み２０ａ内に形成してもよい。
【００２９】
【発明の効果】
本発明の釣竿では、釣竿全体の長さを調整しつつ状況に合わせて釣り操作を行うことができる。この際、元竿の長さにズーム長さが制約されることもない。

The present invention relates to a connecting structure for connecting rods connected in a swinging manner to each other. More specifically, the present invention relates to a connection structure to be applied to a fishing rod designed so that specific rod bodies can be connected and fixed to each other in both the retracted state and the extended state, so that fishing can be performed by changing the length of the entire rod. .
[0002]
[Prior art]
In the conventional fishing rod of the swing-out type, a plurality of cylindrical rod bodies can be inserted into the rod body on the rod base side sequentially from the rod body on the tip side. When fishing, each rod body is sequentially pulled out to the tip side, fitted and fixed, and used as one rod body. On the other hand, at the time of storage, the rod body on the tip side is sequentially stored in the rod body on the rod base side to make it compact.
[0003]
Also, there is a conventional fishing rod of the draw-out type that is designed so that fishing can be performed by changing the length of the entire rod. The fishing rod devised in this manner is, for example, a base rod having a female part fitted on the inner peripheral surface of the tip end side, and a first fitting male part on the outer peripheral surface of the rod base end part, while being near the center in the longitudinal direction. And a former pole having a second fitting male portion on the outer peripheral surface of the upper rod.
In this type of fishing rod, in a state in which the former upper 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 part is referred to as the first fitting male part. In a state where the former upper rod is inserted into the former rod (hereinafter referred to as a "housed state"), the female female part can be fitted with the second male male part (Patent) Reference 1).
[0004]
In this way, the former rod and the former rod can be fitted and fixed to each other in any of the "extended state" and the "stowed state", so that fishing can be performed by changing the entire length of the fishing rod according to the situation. It has become.
[0005]

JP-A-2000-262189 (first and second columns, FIGS. 1 and 2)
[0006]
[Problems to be solved by the invention]
In such a conventional fishing rod, the axial length of the former upper rod stored in the former rod is the difference between the length of the “extended state” and the “housed state” (hereinafter, referred to as “zoom length”). Appears as. That is, the axial length of the former rod determines the zoom length.
In general, a reel sheet is provided on the front end of the original rod for mounting a reel on a front surface thereof so that the reel can be detachably attached thereto, and a grip portion or the like for a fisherman to grip is provided at an end of the original rod. The directional length is limited to a certain length. As described above, since the axial length of the original rod is restricted, the degree of freedom in designing the zoom length is also reduced.
[0007]
An object of the present invention is to provide a fishing rod capable of performing a smooth fishing operation while adjusting the entire length of the fishing rod, and to provide a connecting structure between the rod bodies for increasing the degree of freedom of the zoom length. It is in.
[0008]
[Means for Solving the Problems]
The connecting structure according to the first aspect of the present invention includes a base rod having first rod body holding means at the base end of the base, and a base connected to the front end of the base so as to be able to be inserted into and removed from the base, and a second base at the base end of the base. An upper pole having a body holding means and an upper upper pole which is connected to a tip side of the upper pole so as to be able to be taken in and out of the upper pole.
[0009]
These three rod bodies are in an extended state in which the former upper rod and the former rod are completely drawn out to the front end of the forward dimension rod, and in a stored state in which the former upper rod and the former rod are completely housed in the forward dimension rod. In both of the states, they can be connected and fixed to each other, and specific modes in each state are as follows.
First, in the extended state, the upper rod is pulled out to the tip side of the former rod, and the outer peripheral surface of the rod base side end of the former rod and the inner peripheral surface of the tip side of the former rod are fitted. Further, the outer peripheral surface of the rod base end of the original upper rod and the inner surface of the tip end of the former rod are fitted. Then, the retaining of the rod bodies respectively located on the tip side is restricted, and the mutual rod bodies are connected and fixed.
[0010]
On the other hand, when the original upper pole is stored from the tip side in the former upper pole, and when the rod end side of the former upper rod reaches the rod end side of the former upper rod, the rod end side of the former upper rod becomes higher. The original rod is held by the second rod holding means. The former upper pole and the upper pole held by the second rod holding means are further housed in the former pole from the tip side. When the rod-side end of the former rod reaches the rod-side end of the former rod, the rod-side end of the former rod is held by the first rod body holding means of the former rod (storage state).
[0011]
In this way, in the connecting structure of the rods, the rods can be connected and fixed to each other in both the extended state and the stored state. In particular, when the former rod is interposed, the zoom length is not restricted by the axial length of the former rod, and the degree of freedom is increased.
The connecting structure according to a second aspect of the present invention is the structure according to the first aspect, wherein the second rod holding means is a bottom plug detachably attached to a rod-side end of the upper rod. This bottom plug has a storage recess that opens to the tip side to store and hold the rod end side of the rod, and that the rod side closes to regulate the passage of the rod to the rod side. Have.
[0012]
At the time of the operation of storing the upper most original rod in the upper upper original rod, the rod-side end of the former upper most original rod is stored and held in the storage recess from the opening of the bottom plug. The storage recess is closed at the base of the rod, so that the rod does not pass through the bottom plug and protrude toward the base of the rod. Then, with the storage of the original rod, the original rod is always stored in the original rod.
The connecting structure according to a third aspect of the present invention is the structure according to the first or second aspect, wherein the first rod body holding means is a butt plug detachably attached to a rod base end of the former rod. The buttocks have a storage recess that opens to the tip side to store and hold the rod base end of the former upper rod.
[0013]
During the operation of storing the former upper rod in the former rod, the rod-side end of the former upper rod is stored in the storage recess through the opening of the buttocks.
The connecting structure of Invention 4 is the structure of any of Inventions 1 to 3, wherein the axial length of the former rod is shorter than the axial length of the former rod, and the axial length of the former upper rod is the axis of the former rod. Longer than the direction length.
[0014]
By setting the axial length of such a rod body, the upper rod is completely stored in the former rod in the stored state.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a fishing rod according to one embodiment of the present invention includes a base rod 1 having a reel sheet 6 on which a reel R can be detachably mounted, and a tip side of the base rod 1 sequentially. It has a former pole 2, a former upper pole 3, a middle rod 4, and a head rod 5, which are connected in a swinging manner. These former rods 1 to 5 are tapered cylindrical members formed from a prepreg obtained by impregnating a synthetic resin into carbon fiber or glass fiber or the like. It can be inserted into and removed from the inside of the rod body on the side.
[0016]
When the former upper rod 2 to the tip rod 5 are pulled out to the tip side, the respective rod bodies are located at the outer peripheral surface of the rod side end of the rod body located at the tip side and the rod body located at the rod side. Are fitted to each other at the inner peripheral surface of the end portion of the spike, thereby preventing the spout from slipping off to the spike and enabling the mutual connection and fixing. Further, in particular, the first to third poles 1 to 3 can be connected and fixed to each other in any of the extended state and the stored state, as described later.
[0017]
Further, a fishing line introduction port 7 for introducing the fishing line L from the reel R into the inside of the rod body is formed on the peripheral surface on the tip side of the pole 2 and covers the fishing line introduction port 7 in the axial direction. The fishing line introduction guide 8 is mounted as described above. The fishing line L introduced from the fishing line introduction port 7 penetrates the fishing line passage in the inside of the uppermost pole 3 to the head rod 5. And it is led out from the top guide 9 mounted on the tip side end of the tip pole 5.
[0018]
In this embodiment, the number of rods is five, but the number of rods is set arbitrarily and is not limited to this.
Next, the connection structure of the original rod 1 to the upper original rod 3 will be described in detail.
As schematically shown in FIGS. 2 to 4, each of the original rods 1 to 3 is a cylindrical body having a constant taper. Of the three rods, the rod 3 originally has the longest axial length. The former pole 2 is the shortest and is shorter than the axial length of the former pole 1. For example, if one example is given, assuming that the axial length of the former rod 1 is 50 to 70 cm, the axial length of the former upper rod 2 is about 20 to 30 cm, and the originally upper rod 3 is about 100 to 140 cm. It is the axial length.
[0019]
A tail plug 10 is detachably attached to a rod base end of the former rod 1. The butt plug 10 is attached to the original rod 1 by a known method such as a fitting type or a screw type. When the screw type is used, a thread groove may be formed on the inner peripheral surface of the rod-side end of the rod 1. The tail plug 10 is a plug with a part on the tip side inserted into the rod end side of the original rod 1, and the inside thereof is a storage recess opening toward the tip side. The rod base side end of the upper rod 2 is inserted into the storage recess from the tip side and fitted (see FIG. 2).
[0020]
Such a butt plug 10 can be entirely made of a rubber material. Of course, the tail plug 10 may be formed from a hard synthetic resin or the like. In addition, a plurality of fitting projections projecting in the inner diameter direction may be formed on the inner peripheral surface of the storage recess. By providing such a fitting projection, it is possible to prevent sticking to the former rod 2.
As described above, the former rod 1 and the former upper rod 2 are connected in a so-called swing-out manner, and when the former upper rod 2 is pulled out to the front end side of the former rod 1, the former rod 1 The peripheral surface and the outer peripheral surface of the rod base side end of the former rod 2 are fitted (see FIGS. 3 and 4).
[0021]
A bottom plug 11 is detachably attached to the rod base end of the former rod 2. This bottom plug 11 is also attached to the former rod 2 by a well-known method such as a fitting type or a screw type, like the tail plug 10. When the screw type is used, the point that it is sufficient to form a thread groove on the inner peripheral surface of the rod base end of the former rod 2 is the same as that of the buttocks plug 10. This bottom plug 11 is also a plug whose part on the tip side is inserted into the tip end of the former upper rod 2, and the inside thereof is a storage recess that opens toward the tip side. The end face of the bottom plug 11 on the base side of the rod is closed, and care is taken to prevent the bottom rod 11 from being inserted by the uppermost rod 3 inserted into the storage recess.
[0022]
Further, as shown in FIG. 5, the bottom plug 11 may have a plurality of ventilation holes 11a formed in the rod-side end face. By forming the air hole 11a so as to penetrate in the axial direction from the storage recess, the storing operation of the upper upper rod 3 into the upper upper rod 2 and the operation of pulling out the upper upper rod 2 to the upper upper rod 3 become smooth. As for the bottom plug 11, as shown in FIG. 5, a plurality of fitting projections 11a may be formed on the inner peripheral surface of the storage recess.

As described above, the former upper pole 2 and the upper upper pole 3 are connected in a so-called swing-out manner, and when the upper upper rod 3 is pulled out toward the front end of the upper upper pole 2, The inner peripheral surface of the side end and the outer peripheral surface of the rod end side of the rod 3 are fitted (see FIG. 4).
An auxiliary ring S may be detachably attached to the predetermined peripheral surface of the uppermost pole 3 (see FIG. 2). That is, the gap formed at the tip side end of the original rod 1 in a state where the original upper rod 3 is completely housed in the original rod 1 is filled, and the fitting between the original upper rod 3 and the original rod 1 is stabilized. For this purpose, a rubber ring or the like may be mounted on the circumferential surface of the pole 3 at a predetermined axial position. The auxiliary ring S is originally fixed to the peripheral surface of the rod 3 by a known method such as an adhesive type or a screw type. The reason why the auxiliary ring S is detachable is to remove the upper most pole 3 from the pole side of the former pole 1. In addition, on the peripheral surface of the other position of the former upper rod 3 (the position corresponding to the tip end side of the former upper rod 2 when the former upper rod 3 is completely housed in the former rod 2), A similar auxiliary ring S may be attached, or the peripheral surface of the former pole 2 may be overlaid.

In such a former rod 1, a former upper rod 2, and a former upper rod 3, an extended state in which the former upper rod 3 and the former upper rod 2 are completely drawn to the tip side of the former rod 1 (see FIG. 4). The rod body can be connected and fixed to each other in both the stored state (see FIG. 2) in which the former upper rod 2 and the upper former rod 3 are completely stored inside the former rod 1.
That is, in the extended state as shown in FIG. 4, the former upper rod 2 and the former uppermost rod 3 sequentially drawn out to the front end side of the former rod 1 are respectively connected to the outer peripheral surface of the front end side of the front end of each rod body and the front end of the rod. The rods are fitted on the inner peripheral surface to prevent them from coming off, and the rods are connected and fixed to each other.
[0025]
When the extremity rod 3 is stored in the extremity rod 2 from the stretched state, the extremity end of the extremity rod 3 reaches the bottom plug 11 at the extremity end of the extremity rod 2, The rod base end of the upper rod 3 is held in the storage recess of the bottom plug 11 of the upper rod 2 (see FIG. 3). The storage recess of the bottom plug 11 does not penetrate in the axial direction, and when the original upper rod 3 is further pushed toward the rod base side, the former upper rod 2 and the upper upper rod 3 are connected and inserted into the former rod 1. . When the rod-side end of the former rod 2 reaches the rod-side end of the former rod 1, the rod-side end of the former rod 2 is held by the tail plug 10 of the former rod (storage state).
[0026]
As described above, the rods 1 to 3 can be connected and fixed to each other in both the extended state and the stored state. Then, it is possible to fish according to the fishing situation while adjusting the length of the entire fishing rod. Since the zoom length is not restricted by the axial length of the original rod 1 by interposing the former upper rod 2, an arbitrary zoom can be obtained by appropriately setting the axial length of the former upper rod 2. Can produce length.
[0027]
[Other embodiments]
The tail plug 20 and the bottom plug 21 as shown in FIG. 6 can be employed, and the original rod 1 and the upper rod 2 can be fitted to each other by the tail plug 20 and the bottom plug 21.
The butt plug 20 is of a type that is screwed to the base side of the base pole 1. As in the above embodiment, a storage recess 20a that opens to the tip side is provided inside. On the other hand, the bottom plug 21 is also of a type that is screwed to the rod base side of the former upper rod 2. It has a storage recess 21a that opens to the tip side as in the above embodiment, but is further provided with a fitting male portion 21b that projects to the pole base side. The fitting male portion 21b is a tapered columnar portion that tapers slightly toward the base of the rod.
[0028]
In order to adjust the degree of fitting between the male fitting portion 21b of the bottom plug 21 and the storage recess 20a of the tail plug 20, a fitting projection may be formed in the storage recess 20a as in the above embodiment. .
