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、特に、釣竿を構成する竿体の周面にスライドガイドと呼ばれる軸方向に移動可能な釣糸ガイドを有している釣竿に関する。
【０００２】
【従来の技術】
釣竿の中には、いわゆる振出形式で複数の竿体を連結した釣竿がある。この種の釣竿は、大径に設定された竿元側の竿体内に順次穂先側に連結される竿体が収納可能となっている。そして、釣りを行う際には順次各竿体を引きだして一本の釣竿とし、釣りを終えた際には順次各竿体を竿元側の竿体に収納してコンパクトな状態とする。
【０００３】
このような振出形式の釣竿にあっても、竿元側の竿体の周面に配置されるリールからの釣糸を穂先側に順次案内するために釣糸ガイドを配置する必要がある。しかし、竿体の外周面に配置される釣糸ガイドは竿体を振出形式に収納する際に邪魔になる。そこで、竿体自体が手元側の竿体内に順次収納される振出形式の釣竿では、釣糸ガイドは以下のようなものとなっている。
【０００４】
即ち、竿体は先細りテーパの施されており、各竿体の穂先側端部にはその周面位置に固定されている固定ガイドが配置され、その竿元側には複数のスライドガイドが配置される。このスライドガイドは竿体が挿通した状態で竿体周面に配置されるパイプ部を有し、このパイプ部が竿体の任意の軸方向位置でその外径と合致して固定される。竿体を振出形式に収納する際には、各スライドガイドを固定ガイドまで周面上で穂先側にスライド移動させる。使用時には、各スライドガイドを周面上で竿元側にスライド移動させて任意の位置で固定するのである。
【０００５】
【発明が解決しようとする課題】
ところで、竿体周面に釣糸ガイドを配置する「外通し竿」にあっては、釣糸の竿体周面へのべたつきという問題が指摘されている。即ち、屋外、特に、水辺の野外で用いる釣竿においては竿体周面には雨や水滴等がつきやすく、さらに、水中に投じられる釣糸にも水が付着している。このため、釣糸ガイドと釣糸ガイドとの間において、釣糸が竿体周面にべた付いてしまい、釣糸の円滑な出し入れを阻害する恐れが生じ得るのである。
【０００６】
このため、竿体周面にスクリーン印刷を施して細かい凹凸を設けて釣糸のべたつきを抑える等の工夫が施されてきた。しかし、このようなスクリーン印刷による凹凸形成は耐久性が必ずしも十分ではない。また、竿体周面をスライドガイドが移動するような竿体では、スライドガイドの移動によってスクリーン印刷が剥離乃至毀損してしまう恐れもある。
【０００７】
本発明の課題は、釣糸のべたつき長期にわたって効果的に抑え得る釣竿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の釣竿は、複数の竿体が振出形式に連結されてなる釣竿であって、先細りテーパの施された筒状体である竿体と、竿体の周面を軸方向に移動自在且つ所定位置に固定可能に配置される複数のスライドガイドとを備えている。この竿体は、筒状の本体部と、軸方向に間隔を隔てて形成される本体部より周面が大径厚肉化された部分である複数の肉盛部と、隣り合う肉盛部の軸方向間の本体部の周面に軸方向に連続して螺旋状に形成された突起とを有している。そして、隣り合う肉盛部の本体部からの高さは隣り合う肉盛部の軸方向間の突起の本体部からの高さより高い。一方、複数のスライドガイドは、竿体が挿通した状態で竿体周面に配置されるパイプ状の固定部を有している。そして、１つのスライドガイドの固定部の内径が対応する複数の肉盛部の１つの肉盛部の外径に合致している。
【０００９】
この釣竿では、収納時にあっては、各スライドガイドを穂先側に移動させた上で、各竿体を竿元側の竿体内に順次振出形式で収納してコンパクトな状態にする。使用時にあっては、複数の竿体を順次穂先側に引き出して、振出形式に連結して一本の長い釣竿とする。そして、各竿体の周面に配置されている複数のスライドガイドを順次竿元側に向かってスライド移動させて、それぞれのスライドガイドの固定部を対応する肉盛部に嵌着させて固定する。
【００１０】
この釣竿の竿体の肉盛部間の本体部周面には螺旋状に形成された突起があり、肉盛部上に固定されて用いられるスライドガイドとこれに隣接するスライドガイドとの間での釣糸のべたつきを抑えている。また、スライドガイド自体はその固定部を肉盛部に嵌着させるものであり、肉盛部の高さは突起の高さより高く設定されることから、突起がスライドガイドのスライド移動を阻害しない。また、スライドガイドと突起との接触が少なく相互に毀損しあうことも抑えられる。
【００１１】
発明２の釣竿は、発明１の釣竿であって、突起は炭素繊維を合成樹脂に含浸させたプリプレグ素材からなり、炭素繊維を紐状に加工し、長手方向に配向させたものである。
このような炭素繊維が長手方向に配向された素材が竿体の周面に螺旋状に配置してなる突起が、釣糸の竿体周面へのべたつきを抑えると共に、管状の竿体の潰れ強度や剛性への補強も果たす。一般に、竿体自体もプリプレグ素材から構成されるので、突起と竿体の本体自体が一体的に形成可能であり、突起の強度にも優れることになる。
【００１２】
発明３の釣竿は、発明１または２の釣竿であって、穂先側端部内周面に嵌合雌部を有する大径竿体と、大径竿体の穂先側に振出形式で連結され竿元側端部外周面に嵌合雌部に嵌着可能な第１嵌合雄部を，穂先側の外周面に嵌合雌部に嵌着可能な第２嵌合雄部を有する小径竿体を有している。
この釣竿では、大径竿体と小径竿体とを振出形式に引き出した延伸状態と、大径竿体内に小径竿体を振出形式に収納した収納状態との何れに於いても相互に固定して用いて、釣竿全体の長さを調整して釣りを行える。延伸状態にあっては、釣人は小径竿体の第１嵌合雄部を大径竿体の嵌合雌部に嵌着させて相互に竿体を連結固定する。一方、収納状態にあっては、釣人は小径竿体の第２嵌合雄部を大径竿体の嵌合雌部に嵌着させて相互に竿体を連結固定する。
【００１３】
このような釣竿でも釣糸のべたつき、特に延伸状態における小径竿体周面への釣糸のべたつきが問題となるが、第１嵌合雄部と第２嵌合雄部が肉盛部であり、その間に螺旋状の突起が形成されることで、釣糸のべたつきが可及的に抑えられる。そして、この突起の高さより第１嵌合雄部及び第２嵌合雄部の高さが高いので、小径竿体の出し入れ時における突起の摩耗破損も少ない。
【００１４】
【発明の実施の形態】
［第１実施形態］
本発明の第１実施形態を採用した釣竿は、図１に示すように、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，中竿３，及び穂先竿４とを有している。これら元竿１〜穂先竿４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４は穂先側から順次竿元側の竿体の内部に挿入され出入自在となっている。もっとも、竿体の数は任意に設定するものであり、上述のように４本に限定されるものではない。
【００１５】
元竿１は、外周面に形成されリール（図示せず）を脱着自在に装着可能なリールシート５を有している。このリールシート５は別途合成樹脂等で形成されたパイプ状の部材を所定の位置に配置し固定して形成されている。また、元竿１の竿元側端部内周面には雌ねじ部材（図示せず）が配置され、ここに尻栓６が脱着自在に螺合している。また、元竿１の穂先側端部外周面には固定式の釣糸ガイドも配置されている。さらに、この元竿１の穂先側端部内周面は元上竿２を連結固定するための嵌合雌部となっている。
【００１６】
元上竿２〜穂先竿４は上述のように順次元竿１の穂先側に連結される先細りテーパが形成された竿体である。それぞれの竿体には、振出形式で連結可能なように、穂先側端部内周面に嵌合雌部を竿元側端部に嵌合雌部が必要に応じて形成される。これらの竿体の構造は基本的に同様であるので、中竿３を例にして以下に説明する。
【００１７】
図２及び図３に詳しく示すように、中竿３は、先細りテーパの施された筒状体である本体部１１と、本体部１１の周面上に軸方向に所定の間隔を隔てて形成されている複数の肉盛部１２と、この肉盛部１２と隣接する肉盛部１２との間の本体部１１の周面に形成されている突起１３とを有している。また、この中竿３の周面には、固定式の固定ガイド７と、軸方向に移動自在な複数のスライドガイド２０とが配置されている。
【００１８】
本体部１１が、上述のように、炭素繊維等の強化繊維に合成樹脂を含浸させてなるプリプレグ素材からなる筒状体である。具体的には、所定の先細りテーパの施された芯材にテープ状若しくはシート状のプリプレグ素材を巻回して積層し、これらを焼成し、芯材を引き出して製造される。
肉盛部１２は、本体部１１より周面が大径厚肉化された部分である。具体的には、上述の本体部１１を形成する際に、同様のプリプレグ素材を部分的に巻回して積層し本体部１１と一体的に焼成して形成する。この肉盛部１２は後述のスライドガイド２０が固定される部分であり、配置するスライドガイド２０の数に対応して設ける必要がある。この肉盛部１２の本体部１１周面からの高さ（図２ΔＸ参照）は、後述の突起１３の本体部１１周面からの高さ（図２ΔＹ参照）より高くなるように設定する。即ち、必要な高さを担保し得るようにプリプレグ素材を部分的に積層し焼成後に周面を研磨した上で、肉盛部１２は所定の高さに調整されている。
【００１９】
突起１３は、肉盛部１２とこれに隣り合う肉盛部１２との軸方向間の本体部１１の周面に軸方向に連続して螺旋状に形成されている。具体的には、上述の本体部１１を形成する際に、紐状に加工したプリプレグ素材を所定の本体部１１の周面に螺旋状に巻回して、一体的に焼成してなるものである。この螺旋の軸方向間隔（ピッチ）は３〜４ｍｍ程度の間隔である。突起１３の高さは0.1〜1ｍｍ程度となるように、紐状のプリプレグを加工し若しくは焼成後に周面を研磨して設定される。また、この紐状プリプレグは炭素繊維をその紐の長手方向に配向した上でエポキシ樹脂等の合成樹脂を含浸させたものを用いるのが好ましい。何故なら、このような紐状プリプレグを用いることで、結果的に強化繊維が竿体の周方向に補強されることになり、竿体の潰れ強度・剛性の補強に資するからである。
【００２０】
図１に示すように、固定ガイド７は中竿３の穂先側端部外周面に形成される肉盛部１２上に配置され固定されている。スライドガイド２０は複数であり、この固定ガイド７の竿元側に配置される。両者は、所定の位置に固定されてスライド移動が可能か否かにおいて異なり、その構造は同様であるので、スライドガイド２０を以て以下に説明する。
【００２１】
図２及び図３に示すように、スライドガイド２０は、パイプ状の固定部２１と、固定部２１より起立する脚部２２と、脚部２２の頭端に填め込まれて固定され軸方向に向かって開口しているガイドリング２３とからなる。
固定部２１は、中竿３が挿通した状態で中竿３の周面に配置されるパイプ状の部材である。合成樹脂乃至金属等で形成されその内周面にはゴム素材を配置してもよい。個々のスライドガイド２０の固定部２１は、それぞれその内径が対応する上述の肉盛部１２の外径に合致するように設定されている。そして、先細りテーパの施された中竿３にあっては、固定部２１は対応する肉盛部１２に嵌着しつつこの対応する肉盛部１２より穂先側へはスライド移動可能となるのである。
【００２２】
脚部２２は固定部２１から起立する部分であって、固定部２１とは別途若しくは一体的に形成される。その頭端は軸方向に向かって開口している。そして、この開口にガイドリング２３が填め込まれて固定されている、ガイドリング２３はセラミックス等の硬質部材からなり、釣糸がこの部分を挿通することになる。
なお、固定ガイド７もこのスライドガイド２０と同様の構造を採るが、その固定部が接着剤等によって最も穂先側に位置する肉盛部１２に固定されて、軸方向への移動はできないようになっている。また、以上は中竿３に於いて説明しているが、元上竿２及び穂先竿４も同様の構造を採るものである。
【００２３】
このような釣竿では、収納時にあっては、元上竿２〜穂先竿４に於いて、その周面の各スライドガイド２０を穂先側に移動させた上で、順次、竿体を竿元側の竿体内に振出形式で収納してコンパクトな状態にする。使用時にあっては、穂先竿４から順次穂先側に引き出して、振出形式に相互に連結固定して一本の長い釣竿とする。そして、元上竿２〜穂先竿４の各周面に配置されている複数のスライドガイド２０を順次竿元側にスライド移動させて、それぞれのスライドガイ２０ドの固定部２１を対応する肉盛部１２に嵌着させて固定する。
【００２４】
使用時にあっては、リールシート５にリールを装着した上で、このリールからの釣糸を順次、各釣糸ガイドのガイドリングに挿通させながら、穂先側にその釣糸を案内する。この際、肉盛部１２上に固定されて用いられるスライドガイド２０とこれに隣接するスライドガイド２０との間に形成される突起１３が、スライドガイド２０間で弛む等した釣糸が竿体の本体部１１の周面にべた付いてしまうのを抑えている。また、図３に示すように、スライドガイド２０の固定部２１は肉盛部１２（高さはΔＸである）に嵌着するものであるから、その固定部２１の内径は突起１３の高さ（ΔＹ）より大きくなる。よって、スライドガイド２０の軸方向移動を突起１２が阻害しない。
【００２５】
［第２実施形態］
以下、本発明の第２実施形態を説明する。
本発明の第２実施形態を採用した釣竿は、上記第１実施形態と同様に、元竿３１〜穂先竿３４を有する。中竿３３及び穂先竿３４は上記実施形態と同様の構造を備えるものの、元竿３１と元上竿３２とにあっては、以下のような構成を採用している。
【００２６】
図４及び図５に示すように、元竿３１は、先細りテーパの施された筒状体であり、その穂先側端部内周面に嵌合雌部３１ａを有している。嵌合雌部３１ａは他の部分に比べてその内径が特に小径化した部分であり、その内周面が元上竿３２と嵌着する部分である。また、必要に応じて竿元側端部内周面にも、同様の嵌合雌部を形成してもよい。
【００２７】
元上竿３２は、元竿１の穂先側に振出形式で連結され、嵌合雌部３１ａに嵌着可能な第１嵌合雄部３２ａを竿元側端部外周面に有し、且つ嵌合雌部３１ａに嵌着可能な第２嵌合雄部３２ｂを穂先側の外周面に有している。この第１嵌合雄部３２ａ及び第２嵌合雄部３２ｂはそれぞれ上記第１実施形態における肉盛部に相当する。即ち、元上竿３２の他の部分より周面が大径厚肉化された部分である。そして、それぞれの嵌合雄部３２ａ，３２ｂを元竿１の嵌合雌部３１ａと嵌着させ、収納状態と延伸状態とに於いて相互に連結固定可能となっている。
【００２８】
一方、元上竿３２の第１嵌合雄部３２ａと第２嵌合雌部３２ｂとの間の周面には、螺旋状に連続して軸方向に伸びている突起３３が形成されている。この突起３３は上記第１実施形態と同様であり、紐状に加工したプリプレグ素材を巻回して焼成してなるものである。そして、肉盛部に相当する第１嵌合雄部３２ａ及び第２嵌合雄部３２ｂの高さはこの突起３３の高さより高く設定される。
【００２９】
このような釣竿でも釣糸のべたつき、特に、元上竿３２を元竿３１の穂先側に引き出して固定している延伸状態において、元上竿３２への釣糸のべたつきが問題となるが、これを突起３３が可及的に抑えている。そして、第１嵌合雄部３２ａと第２嵌合雄部３２ｂとが肉盛部であり、この突起３３の高さより第１嵌合雄部３２ａ及び第２嵌合雄部３２ｂの高さが高いので、元上竿２の元竿１への出し入れ時における突起３３と元竿１との摩耗破損を抑えられる。
【００３０】
【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、竿体周面への釣糸のべたつきも防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod used for fishing, and more particularly to a fishing rod having a fishing line guide that is movable in the axial direction, called a slide guide, on the peripheral surface of a rod constituting the fishing rod.
[0002]
[Prior art]
Among fishing rods, there is a fishing rod in which a plurality of rods are connected in a so-called swing-out form. In this type of fishing rod, a rod that is sequentially connected to the tip side can be stored in a rod-side rod that is set to have a large diameter. When fishing, each rod is pulled out to make one fishing rod, and when fishing is finished, each rod is sequentially stored in the rod on the rod side to make it compact.
[0003]
Even in this type of fishing rod, it is necessary to dispose a fishing line guide for sequentially guiding the fishing line from the reel disposed on the peripheral surface of the rod body on the rod side to the tip side. However, the fishing line guides arranged on the outer peripheral surface of the rod are obstructive when the rod is stored in the swing-out form. Therefore, the fishing line guide is as follows in the swing type fishing rod in which the rod body is sequentially housed in the housing on the hand side.
[0004]
In other words, the housings are tapered and taper, a fixed guide fixed to the peripheral surface position is arranged at the end of the tip side of each housing, and a plurality of slide guides are arranged on the side of the collar. Is done. The slide guide has a pipe portion arranged on the circumferential surface of the housing in a state where the housing is inserted, and the pipe portion is fixed to match the outer diameter at an arbitrary axial position of the housing. When the case is stored in the swing-out form, each slide guide is slid to the tip side on the circumferential surface to the fixed guide. At the time of use, each slide guide is slid to the base side on the peripheral surface and fixed at an arbitrary position.
[0005]
[Problems to be solved by the invention]
By the way, in the “outer rod” in which the fishing line guide is arranged on the peripheral surface of the rod, the problem of stickiness of the fishing line to the peripheral surface of the rod has been pointed out. That is, in fishing rods used outdoors, particularly in the waterside, rain and water droplets are easily attached to the peripheral surface of the rod body, and water is also attached to the fishing line thrown into the water. For this reason, there is a possibility that the fishing line sticks to the peripheral surface of the housing between the fishing line guide and the fishing line guide, and hinders the smooth insertion and removal of the fishing line.
[0006]
For this reason, contrivances have been made such as screen printing on the peripheral surface of the body to provide fine irregularities to suppress stickiness of the fishing line. However, such unevenness formation by screen printing does not always have sufficient durability. In addition, in a case where the slide guide moves on the peripheral surface of the case, screen printing may be peeled off or damaged due to the movement of the slide guide.
[0007]
An object of the present invention is to provide a fishing rod that can effectively suppress stickiness of a fishing line over a long period of time.
[0008]
[Means for Solving the Problems]
The fishing rod according to the first aspect of the present invention is a fishing rod in which a plurality of rods are connected in a swing-out manner, and is a rod-like rod-shaped tubular member and a peripheral surface of the rod that is movable in the axial direction. And a plurality of slide guides arranged to be fixed at predetermined positions. The casing includes a cylindrical main body part, a plurality of built-up parts that are thicker and thicker than the main body part spaced apart in the axial direction, and an adjacent built-up part. And a protrusion formed in a spiral shape continuously in the axial direction on the peripheral surface of the main body between the axial directions. And the height from the main-body part of an adjacent build-up part is higher than the height from the main-body part of the protrusion between the axial directions of an adjacent build-up part. On the other hand, the plurality of slide guides have pipe-shaped fixing portions that are arranged on the peripheral surface of the housing in a state where the housing is inserted. And the internal diameter of the fixing | fixed part of one slide guide corresponds to the outer diameter of one built-in part of the some built-up parts.
[0009]
In this fishing rod, when storing, each slide guide is moved to the tip side, and then each rod is sequentially stored in a swing-out manner in the rod-side housing to make it compact. When in use, a plurality of rods are pulled out to the tip side sequentially and connected to a swing type to form one long fishing rod. Then, the plurality of slide guides arranged on the circumferential surface of each housing are sequentially slid toward the base, and the fixing portions of the respective slide guides are fitted and fixed to the corresponding built-up portions. .
[0010]
There is a spirally formed protrusion on the peripheral surface of the main body between the built-up parts of the rod body of this fishing rod, and between the slide guide used by being fixed on the built-up part and the slide guide adjacent thereto The stickiness of the fishing line is suppressed. Further, the slide guide itself is for fitting the fixed portion to the build-up portion, and since the height of the build-up portion is set higher than the height of the projection, the projection does not hinder the slide movement of the slide guide. Further, there is little contact between the slide guide and the protrusion, and it is possible to suppress damage to each other.
[0011]
The fishing rod of the invention 2 is the fishing rod of the invention 1, wherein the protrusion is made of a prepreg material in which carbon fiber is impregnated with a synthetic resin, and the carbon fiber is processed into a string shape and oriented in the longitudinal direction.
Protrusions made of such a material in which carbon fibers are oriented in the longitudinal direction are arranged spirally on the peripheral surface of the rod body to prevent sticking of the fishing line to the rod peripheral surface and the crushing strength of the tubular rod member It also provides reinforcement to rigidity. Generally, since the casing itself is also made of a prepreg material, the protrusion and the main body of the casing can be formed integrally, and the strength of the protrusion is excellent.
[0012]
The fishing rod of the invention 3 is the fishing rod of the invention 1 or 2, and is connected to the tip side of the large-diameter rod body in a swinging manner by a large-diameter rod body having a fitting female portion on the inner peripheral surface of the tip-end portion. A small-diameter housing having a first fitting male portion that can be fitted to the fitting female portion on the outer peripheral surface of the side end portion and a second fitting male portion that can be fitted to the fitting female portion on the outer peripheral surface of the tip side. Have.
In this fishing rod, the large-diameter frame and the small-diameter frame are fixed to each other in either the extended state in which the large-diameter frame and the small-diameter frame are drawn out, or in the stored state in which the small-diameter frame is stored in the large-diameter frame. Can be used to adjust the overall length of the fishing rod. In the extended state, the angler fits and fixes the rods to each other by fitting the first fitting male portion of the small-diameter rod to the fitting female portion of the large-diameter rod. On the other hand, in the housed state, the angler attaches the second fitting male part of the small-diameter frame to the fitting female part of the large-diameter frame, and connects and fixes the frames to each other.
[0013]
Even with such a fishing rod, stickiness of the fishing line, particularly stickiness of the fishing line on the circumferential surface of the small-diameter rod body in the stretched state, is a problem, but the first fitting male part and the second fitting male part are overlay parts, By forming the spiral projection on the fishing line, stickiness of the fishing line is suppressed as much as possible. And since the height of a 1st fitting male part and a 2nd fitting male part is higher than the height of this protrusion, there is also little abrasion damage of the protrusion at the time of taking in and out of a small diameter housing.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
As shown in FIG. 1, the fishing rod employing the first embodiment of the present invention is connected to the main rod 1 and the head side of the main rod 1 in a swinging manner, and the upper rod 2, the middle rod 3, and It has a hot tip 4. These base rods 1 to 4 are taper-shaped tubular members formed from a prepreg obtained by impregnating carbon fiber or glass fiber with a synthetic resin. It is inserted inside the housing on the side and can enter and exit. However, the number of housings is arbitrarily set, and is not limited to four as described above.
[0015]
The main shaft 1 has a reel sheet 5 which is formed on the outer peripheral surface and on which a reel (not shown) can be detachably mounted. The reel sheet 5 is formed by arranging and fixing a pipe-like member separately formed of synthetic resin or the like at a predetermined position. Further, a female screw member (not shown) is disposed on the inner peripheral surface of the base side end portion of the base rod 1, and a tail plug 6 is detachably screwed thereto. In addition, a fixed fishing line guide is also arranged on the outer peripheral surface of the tip side end of the base rod 1. Further, the inner peripheral surface of the tip side end portion of the base rod 1 is a fitting female portion for connecting and fixing the base rod 2.
[0016]
The former upper heel 2 to the tip heel 4 are skeletons having a tapered taper connected to the tip side of the forward dimension heel 1 as described above. In each case, a fitting female part is formed on the inner peripheral surface of the tip side end part and a fitting female part is formed on the base side end part as necessary so that it can be connected in a swinging manner. Since the structures of these casings are basically the same, the following description will be given taking the middle casing 3 as an example.
[0017]
As shown in detail in FIGS. 2 and 3, the intermediate collar 3 is formed on the peripheral surface of the main body 11 with a predetermined interval in the axial direction on the peripheral surface of the main body 11 and the main body 11 which is a tapered taper. A plurality of built-up portions 12 and projections 13 formed on the peripheral surface of the main body portion 11 between the built-up portions 12 and the adjacent built-up portions 12. A fixed fixed guide 7 and a plurality of slide guides 20 that are movable in the axial direction are arranged on the peripheral surface of the intermediate collar 3.
[0018]
As described above, the main body 11 is a tubular body made of a prepreg material obtained by impregnating a reinforcing fiber such as carbon fiber with a synthetic resin. Specifically, a tape-like or sheet-like prepreg material is wound around a core material having a predetermined taper taper, laminated, fired, and the core material is drawn out.
The built-up portion 12 is a portion in which the peripheral surface is larger in diameter and thicker than the main body portion 11. Specifically, when forming the above-described main body part 11, the same prepreg material is partially wound and laminated, and is fired integrally with the main body part 11. The build-up portion 12 is a portion to which a slide guide 20 described later is fixed, and needs to be provided corresponding to the number of slide guides 20 to be arranged. The height (see FIG. 2ΔX) of the built-up portion 12 from the peripheral surface of the main body portion 11 is set to be higher than the height (see FIG. 2ΔY) of the protrusion 13 described later from the peripheral surface of the main body portion 11. That is, the build-up portion 12 is adjusted to a predetermined height after partially laminating the prepreg material so as to ensure the required height and polishing the peripheral surface after firing.
[0019]
The protrusion 13 is formed in a spiral shape continuously in the axial direction on the circumferential surface of the main body 11 between the built-up portion 12 and the built-up portion 12 adjacent thereto. Specifically, when forming the main body 11 described above, the prepreg material processed into a string shape is spirally wound around the peripheral surface of the predetermined main body 11 and integrally fired. . The distance (pitch) between the spirals in the axial direction is about 3 to 4 mm. The height of the protrusion 13 is set by processing the string-like prepreg or polishing the peripheral surface after firing so that the height is about 0.1 to 1 mm. Moreover, it is preferable to use this string-like prepreg which has carbon fibers oriented in the longitudinal direction of the string and impregnated with a synthetic resin such as an epoxy resin. This is because by using such a string-like prepreg, the reinforcing fibers are reinforced in the circumferential direction of the casing, which contributes to reinforcing the crushing strength and rigidity of the casing.

As shown in FIG. 1, the fixed guide 7 is arranged and fixed on the built-up portion 12 formed on the outer peripheral surface of the tip side end portion of the middle rod 3. There are a plurality of slide guides 20, which are arranged on the base side of the fixed guide 7. Both are different in whether or not they can be slid and fixed at a predetermined position, and the structure is the same. Therefore, the following description will be given with the slide guide 20.
[0021]
As shown in FIGS. 2 and 3, the slide guide 20 includes a pipe-like fixing portion 21, a leg portion 22 that stands up from the fixing portion 21, and is fixed by being fitted into the head end of the leg portion 22. It consists of the guide ring 23 which opens toward.
The fixing portion 21 is a pipe-shaped member that is disposed on the circumferential surface of the middle collar 3 in a state where the middle collar 3 is inserted. A rubber material may be disposed on the inner peripheral surface of the synthetic resin or metal. The fixed portions 21 of the individual slide guides 20 are set so that the inner diameter thereof matches the outer diameter of the above-described overlaying portion 12. Then, in the middle flange 3 with the tapered taper, the fixing portion 21 can be slid to the tip side from the corresponding built-up portion 12 while being fitted to the corresponding built-up portion 12. .
[0022]
The leg portion 22 is a portion that stands up from the fixing portion 21 and is formed separately or integrally with the fixing portion 21. The head end is open in the axial direction. The guide ring 23 is fixed by being inserted into the opening. The guide ring 23 is made of a hard member such as ceramics, and the fishing line passes through this portion.
The fixed guide 7 also has the same structure as the slide guide 20, but the fixed portion is fixed to the buildup portion 12 located closest to the tip by an adhesive or the like so that it cannot move in the axial direction. It has become. Moreover, although the above is demonstrated in the middle collar 3, the former collar 2 and the tip collar 4 also take the same structure.
[0023]
In such a fishing rod, at the time of storage, the slide guides 20 on the peripheral surface are moved to the tip side in the former rod 2 to the tip rod 4, and the rod body is sequentially moved to the root side. It is housed in a swinging-out form in a housing so that it is compact. At the time of use, it is pulled out sequentially from the tip 4 to the tip side, and is connected and fixed to the swing type to make one long fishing rod. Then, the plurality of slide guides 20 arranged on the respective peripheral surfaces of the upper collar 2 to the tip collar 4 are sequentially slid to the collar side, and the fixed portions 21 of the respective slide guides 20 are correspondingly built up. It is fitted and fixed to the part 12.
[0024]
In use, after the reel is mounted on the reel sheet 5, the fishing line from the reel is guided to the tip side while being sequentially inserted through the guide ring of each fishing line guide. At this time, the fishing line in which the projection 13 formed between the slide guide 20 used by being fixed on the built-up portion 12 and the slide guide 20 adjacent thereto is loosened between the slide guides 20 is the main body of the housing. The sticking to the peripheral surface of the part 11 is suppressed. Further, as shown in FIG. 3, since the fixed portion 21 of the slide guide 20 is fitted to the build-up portion 12 (height is ΔX), the inner diameter of the fixed portion 21 is the height of the protrusion 13. It becomes larger than (ΔY). Therefore, the protrusion 12 does not hinder the axial movement of the slide guide 20.
[0025]
[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described.
The fishing rod that employs the second embodiment of the present invention has a base rod 31 to a tip rod 34 as in the first embodiment. Although the middle rod 33 and the tip rod 34 have the same structure as that of the above-described embodiment, the following configuration is adopted for the former rod 31 and the former upper rod 32.
[0026]
As shown in FIGS. 4 and 5, the base rod 31 is a cylindrical body with a tapered taper, and has a fitting female portion 31 a on the inner peripheral surface of the tip side end portion. The fitting female portion 31a is a portion whose inner diameter is particularly reduced compared to the other portions, and the inner peripheral surface thereof is a portion where the inner flange 32 is fitted. Moreover, you may form the same fitting female part also in the collar side edge part inner peripheral surface as needed.
[0027]
The upper upper collar 32 is connected to the tip side of the former collar 1 in a swinging manner, and has a first fitting male portion 32a that can be fitted to the fitting female portion 31a on the outer peripheral surface of the proximal side, and is fitted. A second fitting male portion 32b that can be fitted to the mating female portion 31a is provided on the outer peripheral surface on the tip side. Each of the first fitting male part 32a and the second fitting male part 32b corresponds to the build-up part in the first embodiment. That is, the peripheral surface is a part having a larger diameter and a thicker wall than the other part of the original upper collar 32. And each fitting male part 32a, 32b is made to fit with the fitting female part 31a of the main shaft 1, and it can connect and fix mutually in the accommodation state and the extending | stretching state.
[0028]
On the other hand, on the peripheral surface between the first fitting male part 32a and the second fitting female part 32b of the upper collar 32, a protrusion 33 extending in the axial direction continuously in a spiral shape is formed. . The protrusions 33 are the same as in the first embodiment, and are formed by winding and firing a prepreg material processed into a string shape. The heights of the first fitting male part 32 a and the second fitting male part 32 b corresponding to the build-up part are set higher than the height of the protrusion 33.
[0029]
Even with such a fishing rod, stickiness of the fishing line, particularly in the stretched state where the former upper rod 32 is pulled out and fixed to the tip of the former rod 31, the stickiness of the fishing line to the former upper rod 32 becomes a problem. The protrusion 33 suppresses as much as possible. And the 1st fitting male part 32a and the 2nd fitting male part 32b are build-up parts, and the height of the 1st fitting male part 32a and the 2nd fitting male part 32b is higher than the height of this protrusion 33. Since it is high, it is possible to suppress wear damage between the protrusion 33 and the main rod 1 when the upper upper rod 2 is put in and out of the main rod 1.
[0030]
【The invention's effect】
In the fishing rod of the present invention, stickiness of the fishing line to the circumferential surface of the rod body can be prevented while adjusting the length of the entire fishing rod.
