Abstract

<P>PROBLEM TO BE SOLVED: To effectively prevent rod bodies from being mutually stuck by adhesion in a shake out type fishing rod. <P>SOLUTION: This fishing rod is constituted by connecting the several rod bodies in a shake out type. For example, a middle rod body 3 is connected to the tip side of a base rod body 2 having an engaging female part 2a in the inside surface of the tip side. The middle rod 3 has a large diameter part 3a which is a step larger than the peripheral surface of the base rod side, does not change the diameter in the shaft direction and contacts with the engaging female part 2a at the tip end. In the middle rod 3, ribs 10 are arranged on the periphery of the large diameter part 3a in the base rod side. The ribs are formed plurally at intervals in the peripheral direction and to be higher than the periphery of the large diameter part 3a in the base rod side by bringing the ribs to contact with the engaging female part 2a so as to meet with the taper of the engaging part 2a of the base rod 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は複数の竿体を振出形式に連結してなる釣竿に関する。   The present invention relates to a fishing rod formed by connecting a plurality of rods in a swinging manner.

従来の振出形式と呼ばれる連結手法を採用した釣竿は、穂先側端部内周を嵌合雌部とする大径竿体と、竿元側端部外周を嵌合雄部として大径竿体の穂先側に連結される小径竿体とを有している。この振出形式の釣竿では、大径竿体内に穂先側から小径竿体が挿入され出し入れ自在となっている。そして、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。   A fishing rod that employs a connecting method called a conventional swing type is a large-diameter rod with the inner periphery of the tip end side as a mating female part, and the tip of a large-diameter rod with the outer periphery of the heel side end as a mating male part. And a small-diameter housing connected to the side. In this swing type fishing rod, a small-diameter rod is inserted into the large-diameter rod from the tip side so that it can be inserted and removed freely. And when fishing, each rod is pulled out to the tip side sequentially and fitted and fixed to be used as one rod. On the other hand, at the time of storage, the body on the tip side is sequentially stored in the body on the base side to make it compact.

振出形式の釣竿において生じる問題の１つに、連結時に竿体同士が固着してしまうというものがある。即ち、小径竿体を大径竿体の穂先側に引き出して嵌合雄部と嵌合雌部とを嵌着させた場合、水辺で用いられる釣竿においては水やゴミ等が嵌合部分に入り込む等して、竿体同士が不当に強固に固着してしまう場合がある。そこで、このような竿体同士の固着を防止するために、嵌合部分に穴や溝を形成した釣竿が提案されている（特許文献１等参照）。
特開２００２−２０９４７８号公報 One of the problems that arise in the swing-type fishing rod is that the rods stick together when connected. That is, when a small-diameter rod is pulled out to the tip of the large-diameter rod and the fitting male part and the fitting female part are fitted, water, dust, etc. enter the fitting part in a fishing rod used on the waterside. For example, the housings may be unduly firmly fixed. Therefore, a fishing rod having holes and grooves formed in the fitting portion has been proposed in order to prevent such sticking of the rods (see Patent Document 1).
JP 2002-209478 A

確かに、旧来の固着防止を図った釣竿においても固着防止効果が期待できる。しかし、固着防止の効果は、嵌合雄部や嵌合雌部に形成する穴や溝の大きさなどに必ずしも比例せず、どのような形状・大きさで嵌合雄部や嵌合雌部に穴や溝などを形成するのが最も効果的なのか必ずしも明らかではなかった。また、穴や溝などを過剰に形成すると、使用時に応力が集中し易い嵌合部分の強度を担保するという観点からも好ましくない。   Certainly, anti-sticking effects can be expected even in fishing rods that have been designed to prevent sticking. However, the effect of preventing sticking is not necessarily proportional to the size of the hole or groove formed in the mating male part or mating female part, but in any shape and size, the mating male part or mating female part It is not always clear whether it is most effective to form holes or grooves in the surface. Further, if holes and grooves are formed excessively, it is not preferable from the viewpoint of securing the strength of the fitting portion where stress is likely to concentrate during use.

本発明の課題は、振出形式の釣竿にあって、効果的に竿体同士の固着を防止することにある。   It is an object of the present invention to prevent sticking of rod bodies effectively in a swing type fishing rod.

本発明の釣竿は、複数の竿体を振出形式に連結した釣竿であって、穂先側ほど小径化するテーパが施された筒状体であり、穂先側内周面が嵌合雌部となっている第１竿体と、第１竿体の穂先側に振出形式に連結されており、竿元側の外周面が他の部分より一段大径化しており軸方向において径が変化せず且つ穂先側端部において嵌合雌部に当接する太径部分となっている第２竿体と、第２竿体の太径部分の竿元側の周面に周方向に間隔を隔てて複数配置され、竿元側ほど太径部分の周面より高くなるように第１竿体の嵌合雌部のテーパに合わせて嵌合雌部に接触可能に形成されているリブとを備えている。   The fishing rod of the present invention is a fishing rod in which a plurality of rods are connected in a swing-out manner, and is a tubular body that is tapered so that the diameter of the tip side becomes smaller, and the inner peripheral surface of the tip side becomes a fitting female part. The first housing is connected to the tip of the first housing in a swing-out manner, the outer peripheral surface of the foot side is one step larger in diameter than the other parts, and the diameter does not change in the axial direction and A plurality of second casings that are large diameter portions that come into contact with the fitting female portion at the end of the tip side and a plurality of circumferentially spaced circumferential surfaces on the base side of the large diameter portion of the second casing And a rib formed so as to be able to come into contact with the fitting female portion in accordance with the taper of the fitting female portion of the first casing so as to be higher than the peripheral surface of the larger diameter portion toward the base side.

この釣竿は、使用するに当たり、第２竿体を第１竿体の穂先側に引き出して使用される。第２竿体を第１竿体の穂先側に引き出すと、第２竿体の竿元側端部が大径竿体の穂先側端部内周面の嵌合雌部に嵌着する。具体的には、太径部分の穂先側端部の周縁が第１竿体の嵌合雌部に周状（但し、一定の幅あり）に接触する。さらに、太径部分の竿元側において、複数のリブがそれぞれ第１竿体の嵌合雌部に軸方向に延びる線状に（但し、一定の幅あり）接触する。   In use, this fishing rod is used by pulling the second rod to the tip side of the first rod. When the second casing is pulled out toward the tip of the first casing, the base end of the second casing is fitted to the fitting female portion on the inner peripheral surface of the tip end of the large diameter casing. Specifically, the peripheral edge of the end portion on the tip side of the large-diameter portion contacts the fitting female portion of the first housing in a circumferential shape (however, with a certain width). Further, on the flange side of the large-diameter portion, the plurality of ribs respectively contact the fitting female portion of the first housing in a linear shape (however, with a certain width) extending in the axial direction.

このように、第２竿体の竿元側の部分が、第１竿体の穂先側の内周面に対して、穂先側で周状に、竿元側で軸方向に線状に接触することで、竿体同士の固着を防止しつつ充分な嵌合力を演出する。また、使用時に応力が集中し易い竿体同士の連結部分にリブを設けることで、連結部分の強度を向上させることも可能となる。   In this way, the part on the heel side of the second casing is in contact with the inner peripheral surface on the tip side of the first casing in a line shape on the tip side and linearly in the axial direction on the heel side. Thus, sufficient fitting force is produced while preventing the sticking of the casings. Moreover, it becomes possible to improve the intensity | strength of a connection part by providing a rib in the connection part of the housings where stress tends to concentrate at the time of use.

また、第２竿体は繊維強化樹脂から形成されており、リブは第２竿体と一体的に形成してもよい。例えば、(a)リブを形成するために補助用に繊維強化樹脂を積層して、第２竿体の管状部分を形成するための繊維強化樹脂と一体成型する方法や、(b)太径部分を補助用の繊維強化樹脂を積層して、第２竿体の管状部分を形成するための繊維強化樹脂と一体成型した後に、太径部分の周面を削ってリブを形成する方法等が考えられる。いずれにせよ、リブと第２竿体自体とを一体的に形成することで、リブの強度を十分に高めることができる。   Further, the second casing may be formed from a fiber reinforced resin, and the rib may be formed integrally with the second casing. For example, (a) a method of laminating a fiber reinforced resin for auxiliary to form a rib and integrally molding with a fiber reinforced resin for forming a tubular portion of the second housing, or (b) a large diameter portion A method for forming ribs by laminating the auxiliary fiber reinforced resin and integrally molding it with the fiber reinforced resin for forming the tubular portion of the second housing, and then cutting the peripheral surface of the large diameter portion, etc. It is done. In any case, the strength of the rib can be sufficiently increased by integrally forming the rib and the second casing itself.

また、リブは合成樹脂製部材であり、第２竿体の太径部分の周面に貼り付けてもよい。このリブは第２竿体の太径部分に対して接着しても、脱着自在としてもよい。脱着自在とすれば、繰り返し使用してリブが摩耗した場合に、リブを交換することで嵌着力を回復させることもできる。さらに、リブを印刷されたインキから形成してもよい。このインキによる形成とは、例えば、スクリーン印刷等である。   Moreover, a rib is a synthetic resin member and may be affixed on the peripheral surface of the large diameter part of a 2nd housing. This rib may be bonded to the large-diameter portion of the second casing or may be removable. If it is made detachable, the fitting force can be recovered by exchanging the rib when the rib is worn after repeated use. Further, the ribs may be formed from printed ink. This ink formation is, for example, screen printing.

このようなリブは太径部分の軸方向長さの１／２以下の軸方向長さを有するように設定するのが好ましい。なお、太径部分の軸方向長さは前記嵌合雌部の軸方向長さより短く設定するのが好ましい。このような軸方向長さにそれぞれを設定することで、竿体同士の固着を良好に抑えられる。   Such a rib is preferably set so as to have an axial length of 1/2 or less of the axial length of the large diameter portion. The axial length of the large diameter portion is preferably set shorter than the axial length of the fitting female portion. By setting each of these axial lengths, it is possible to satisfactorily suppress the sticking between the casings.

さらに、複数のリブは太径部分の周面に螺旋状に並ぶように形成してもよい。一般に、第１竿体と第２竿体とをそれぞれの軸方向に過大に引っ張ることで、両者の嵌着部分の固着が進む。螺旋状のリブを形成することで、このような軸方向への過大な引っ張りの際の負荷を螺旋方向に散らすことができる。   Further, the plurality of ribs may be formed so as to be spirally arranged on the peripheral surface of the large-diameter portion. Generally, the first housing and the second housing are pulled excessively in the respective axial directions, so that the fitting portions of both are fixed. By forming the spiral rib, it is possible to disperse the load at the time of such excessive pulling in the axial direction in the spiral direction.

なお、第１竿体の嵌合雌部には不織布を積層してもよい。リブが嵌合雌部に嵌着する際の軋みが抑え得る。   In addition, you may laminate a nonwoven fabric in the fitting female part of a 1st housing. The stagnation when the rib is fitted to the fitting female part can be suppressed.

本発明によれば、振出形式の釣竿において生じがちな竿体同士の嵌着部分の固着を防止できる。   ADVANTAGE OF THE INVENTION According to this invention, the adhering of the fitting part of the rod bodies which are likely to arise in the swing type fishing rod can be prevented.

［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。 [First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

（釣竿全体について）
図１に示すように、本発明の第１実施形態を採用した中通し竿は、例えば、元竿１と、元竿１の穂先側に振出形式で連結された元上竿２と、元上竿２の穂先側に振出形式で連結された中竿３及び穂先竿４とを有している。 (About the entire fishing rod)
As shown in FIG. 1, the punch through which the first embodiment of the present invention is adopted includes, for example, a marshal bar 1, an upper barb 2 connected in a swinging manner to the tip side of the barb 1, It has a middle rod 3 and a tip rod 4 connected to the tip side of the rod 2 in a swinging manner.

元竿１は、先細りのテーパが施された筒状体であり、例えば、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から形成される。元竿１の竿元側端部には尻栓９が脱着自在に装着される。また、元竿１の周面には、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が設けられている。さらに、元竿１の穂先側端部にはリールからの釣糸を竿体内に導入するための釣糸導入口６及び釣糸導入口６に釣糸を案内するための導入ガイド７が配置される。   The main rod 1 is a cylindrical body with a tapered taper, and is formed of, for example, a prepreg in which a reinforcing fiber such as a carbon fiber is impregnated with a synthetic resin. A butt plug 9 is detachably attached to the end of the heel 1 on the heel side. In addition, a reel sheet 5 on which a reel (not shown) can be detachably mounted is provided on the peripheral surface of the main shaft 1. Further, a fishing line introduction port 6 for introducing the fishing line from the reel into the rod body and an introduction guide 7 for guiding the fishing line to the fishing line introduction port 6 are disposed at the end of the tip of the maroon 1.

元上竿２〜穂先竿４は、それぞれ順次竿元側に位置する竿体内に穂先側から収納可能に連結されている。後に詳しく説明するように、必要に応じて各竿体の穂先側端部内周面は嵌合雌部となっている。また、必要に応じて各竿体の竿元側端部外周面には太径部分が形成される。そして、両者が嵌着乃至接触することで、穂先側に位置する竿体が、竿元側に位置する竿体から穂先側に飛び出してしまうことがない。また、穂先側に位置する竿体を穂先側に引き出した際に、竿元側に位置する竿体の穂先側端部に穂先側に位置する竿体が連結され固定されることになる。   The former upper collar 2 to the inner ear basket 4 are sequentially connected to the casing located on the proximal side so as to be housed from the leading edge side. As will be described in detail later, the inner peripheral surface of the tip end portion of each housing is a fitting female portion as necessary. Moreover, a large diameter part is formed in the outer peripheral end part outer peripheral surface of each housing as needed. And since both are fitted or contacted, the housing located on the tip side does not jump out from the housing located on the foot side to the tip side. Moreover, when the rod body located on the tip side is pulled out to the tip side, the rod body located on the tip side is connected and fixed to the end portion on the tip side of the rod located on the tip side.

なお、元上竿２〜穂先竿４の内部は釣糸が挿通可能な釣糸通路となっている。そして、必要に応じて、各竿体の内周面には釣糸と内周面との接触面積を低減するための釣糸支持突起などが形成される。そして、穂先竿４の穂先側端部にはトップガイド８が取り付けられ、釣糸はトップガイド８から外部に導出されることになる。
（元上竿２と中竿３とについて）
続いて、元上竿２と中竿３とを例に挙げて、両竿体の連結部分について詳しく説明する。 In addition, the inside of the Motogami rod 2 to the tip rod 4 is a fishing line passage through which a fishing line can be inserted. And if necessary, a fishing line support projection or the like for reducing the contact area between the fishing line and the inner peripheral surface is formed on the inner peripheral surface of each housing. A top guide 8 is attached to the end of the tip of the tip 4 and the fishing line is led out from the top guide 8.
(About Motogami 2 and Nakajo 3)
Subsequently, taking the former collar 2 and the middle collar 3 as an example, the connecting portion of both the casings will be described in detail.

図２に示すように、元上竿２の穂先側に出し入れ自在に中竿３が連結されてる。元上竿２は、上述のように先細りテーパの施された筒状体であり、穂先側端部内周面が嵌合雌部２ａとなっている。嵌合雌部２ａも穂先側ほど小径化するテーパ面である。   As shown in FIG. 2, the middle hook 3 is connected to the tip side of the former upper hook 2 so as to be freely inserted and removed. The former upper collar 2 is a cylindrical body with a tapered taper as described above, and the inner peripheral surface of the tip side end part is a fitting female part 2a. The fitting female portion 2a is also a tapered surface with a smaller diameter toward the tip side.

一方、図２及び図３に示すように、中竿３も元上竿２と同様に先細りテーパの施された筒状体である。もっとも、竿元側端部においては、他の隣接する部分より一段大径化した太径部分３ａが形成されている。この太径部分３ａは軸方向において径の変化しない部分となっている。この太径部分３ａの外径は、図２に示すように、元上竿２の穂先側端部より幾分竿元側に入り込んだ軸方向位置での元上竿２の内径に合致するように設定される。即ち、太径部分３ａの穂先側端部の周縁が元上竿２の嵌合雌部２ａに周状に接触するように設定されている。このように太径部分３ａの外径を設定することで、元上竿２から中竿３を引き出して連結した場合に、太径部分３ａは外部に露出することがない。結果的に、太径部分３ａの軸方向長さは、対応する元上竿２の嵌合雌部２ａの軸方向長さより短くなる。   On the other hand, as shown in FIGS. 2 and 3, the intermediate collar 3 is also a cylindrical body with a tapered taper like the former collar 2. However, a large-diameter portion 3a that is one step larger in diameter than other adjacent portions is formed at the heel side end. The large diameter portion 3a is a portion where the diameter does not change in the axial direction. As shown in FIG. 2, the outer diameter of the large-diameter portion 3 a matches the inner diameter of the upper collar 2 at the axial position slightly entering the heel side from the tip end of the upper collar 2. Set to That is, the peripheral edge of the end portion on the tip side of the large diameter portion 3 a is set so as to contact the fitting female portion 2 a of the upper collar 2 in a circumferential shape. By setting the outer diameter of the large-diameter portion 3a in this manner, the large-diameter portion 3a is not exposed to the outside when the intermediate collar 3 is pulled out from the upper collar 2 and connected. As a result, the axial direction length of the large diameter portion 3a is shorter than the axial length of the fitting female portion 2a of the corresponding upper collar 2.

また、この太径部分３ａの竿元側の周面には複数のリブ１０が形成されている。リブ１０は、例えば、４つのリブ１０をそれぞれ周方向に９０度変位するように配置する。個々のリブ１０は太径部分３ａの竿元側端部から軸方向に延びており、竿元側ほど高さが高くなるような部材である。個々のリブ１０の傾斜は、元上竿２の嵌合雌部２ａのテーパに合わせて設定されている。即ち、個々のリブ１０は嵌合雌部２ａに軸方向に延びる線状（もっとも、一定の幅がある）に接触するように設定されている。なお、個々のリブ１０は、図２及び図３に示すように、竿元側ほど幅広に形成してもよい。リブ１０の軸方向長さは太径部分３ａの軸方向長さの１／２を超えない程度に設定するのが好ましい。何故なら、太径部分３ａの穂先側端縁部分は、嵌合雌部２ａに周当たりさせて、竿元側部分をリブ１０により嵌合させることで、嵌合部分同士の固着を抑えるので、リブ１０の軸方向長さが太径部分３ａの軸方向長さの１／２を超えると、リブの径調整の精度若しくは、後述のような周面研磨加工において相当な精度を要するためである。   In addition, a plurality of ribs 10 are formed on the circumferential surface on the base side of the large diameter portion 3a. For example, the ribs 10 are arranged so that the four ribs 10 are each displaced 90 degrees in the circumferential direction. Each rib 10 is a member that extends in the axial direction from the heel side end of the large-diameter portion 3a and has a height that increases toward the heel side. The inclination of each rib 10 is set according to the taper of the fitting female part 2a of the upper collar 2. That is, each rib 10 is set so as to contact the fitting female portion 2a in a linear shape (although having a certain width) extending in the axial direction. In addition, as shown in FIG.2 and FIG.3, you may form each rib 10 so that the width | variety side is wider. The axial length of the rib 10 is preferably set to a level that does not exceed 1/2 of the axial length of the large diameter portion 3a. Because the tip end side edge portion of the large diameter portion 3a perimeters around the fitting female portion 2a, and the heel side portion is fitted by the rib 10, thereby suppressing the fixation between the fitting portions. This is because when the axial length of the rib 10 exceeds 1/2 of the axial length of the large-diameter portion 3a, the accuracy of adjusting the diameter of the rib or a considerable accuracy in circumferential polishing as described later is required. .

このような中竿３は、例えば、以下のようにして製造することができる。   Such a middle collar 3 can be manufactured as follows, for example.

まず、所定のテーパを施した芯材に炭素繊維強化樹脂等からなるプリプレグ素材をテープ状若しくはシート状に加工したものを巻回する。巻回したプリプレグ素材の竿元側端部の周面に、太径部分３ａを形成するために、補助用のプリプレグ素材を積層する。さらに、補助用プリプレグの周面の竿元側端部に、周方向に間隔を隔ててリブ１０を形成するための短冊状のプリプレグを貼り付ける。その後、これらを焼成し、周面を研磨し、所定のテーパ乃至外径に設定する。もっとも、リブ１０はプリプレグ素材ではなく別の部材、例えば、別途成型した合成樹脂部材などを貼り付けて形成してもよい。   First, a core material having a predetermined taper and a prepreg material made of carbon fiber reinforced resin or the like processed into a tape shape or a sheet shape is wound. In order to form the large-diameter portion 3a on the circumferential surface of the base side end portion of the wound prepreg material, an auxiliary prepreg material is laminated. Further, a strip-shaped prepreg for forming the ribs 10 is pasted on the base side end of the peripheral surface of the auxiliary prepreg at intervals in the circumferential direction. Thereafter, these are fired, the peripheral surface is polished, and set to a predetermined taper or outer diameter. However, the rib 10 may be formed by attaching another member, for example, a separately molded synthetic resin member, instead of the prepreg material.

なお、ここでは、元上竿２と中竿３とにおいて、両者の連結部分を説明しているが、他の竿体に於いても同様の構造を採用する。   In addition, although the connection part of both is demonstrated here in the former collar 2 and the middle collar 3, the same structure is employ | adopted also in another casing.

このように構成された釣竿は、使用するに当たり、穂先竿４から順次穂先側に引き出して、順次竿体同士を連結して一本の長い釣竿として用いられることになる。例えば、中竿３を元上竿２の穂先側に引き出すと、図２に示すように、中竿３の竿元側端部が元上竿２の穂先側端部内周面の嵌合雌部２ａに嵌着する。詳しく述べれば、中竿３の太径部分３ａの穂先側端部の周縁が元上竿２の嵌合雌部２ａに周状に接触する。なお、この「周状」の接触にあってはある程度の幅が生じ得る。また、中竿３の太径部分３ａの竿元側において、複数のリブ１０がそれぞれ元上竿２の嵌合雌部２ａに軸方向に延びる線状に接触する。なお、この「線状」の接触にあってもある程度の幅が生じ得る。
このように、中竿３の竿元側の部分が、その竿元側に隣接する元上竿２の穂先側の内周面に対して、穂先側で周状に且つ竿元側で軸方向に線状に接触することで、竿体同士の固着を防止しつつ充分な嵌合力を演出している。軸方向に離れた２つの部位で中竿３と元上竿２とが接触し嵌着することで、不要な固着が生じにくく、且つ、十分な嵌合力を演出できる。 In use, the fishing rod constructed as described above is pulled out from the tip rod 4 to the tip side sequentially, and the rods are sequentially connected to be used as one long fishing rod. For example, when the middle collar 3 is pulled out to the tip side of the former collar 2, as shown in FIG. 2, the collar-side end of the middle collar 3 is a fitting female part on the inner peripheral surface of the tip-side end of the former collar 2. 2a. More specifically, the peripheral edge of the tip side end of the large-diameter portion 3a of the middle collar 3 contacts the fitting female part 2a of the upper collar 2 in a circumferential manner. In this “circumferential” contact, a certain amount of width may occur. In addition, on the heel side of the large-diameter portion 3a of the intermediate collar 3, the plurality of ribs 10 are in contact with the fitting female portions 2a of the upper collar 2 in a linear shape extending in the axial direction. It should be noted that a certain amount of width can occur even in this “linear” contact.
In this way, the heel side portion of the middle heel 3 is circumferentially on the tip side and axially on the heel side with respect to the inner peripheral surface on the tip side of the former upper heel 2 adjacent to the heel side. By making a linear contact with each other, a sufficient fitting force is produced while preventing the sticking between the casings. Since the middle collar 3 and the upper collar 2 are brought into contact with and fitted at two portions separated in the axial direction, unnecessary fixation is unlikely to occur and a sufficient fitting force can be produced.

［第２実施形態］
第１実施形態の変形例である第２実施形態を採用した中通し竿を以下に示す。 [Second Embodiment]
A through hole that employs the second embodiment, which is a modification of the first embodiment, will be described below.

この中通し竿も、第１実施形態と同様に、元竿１と、元竿１の穂先側に振出形式で連結された元上竿２と、元上竿２の穂先側に振出形式で連結された中竿３及び穂先竿４とを有している。元上竿２〜穂先竿４は、それぞれ順次竿元側に位置する竿体内に穂先側から収納可能に連結されており、必要に応じて、各竿体の穂先側端部内周面は嵌合雌部となっている。また、必要に応じて、各竿体の竿元側端部外周面には太径部分が形成される。   As with the first embodiment, this threading hook is also connected in a swinging manner to the heel 1 of the former heel 1, the former heel 2 connected to the tip of the heel 1 in the swinging manner, and the leading end of the former heel 2 It has a middle rod 3 and a tip rod 4. Motogami cocoons 2 to 4 are connected to the housing located on the heel side in such a way that they can be stored from the side of the stylus. It is a female part. Moreover, a thick part is formed in the outer peripheral part outer peripheral surface of each housing | casing as needed.

この中通し竿の元上竿１２と中竿１３との連結部分を図４に示す。この元上竿１２の穂先側に出し入れ自在に中竿１３が連結されている。元上竿１２は、第１実施形態と同様に、先細りテーパの施された筒状体であり、穂先側端部内周面が嵌合雌部１２ａとなっている。嵌合雌部１２ａも穂先側ほど小径化するテーパ面である。   FIG. 4 shows a connecting portion between the former upper collar 12 and the middle collar 13 of the center thread. A middle collar 13 is connected to the tip side of the former upper collar 12 so as to be freely inserted and removed. Similar to the first embodiment, the former upper collar 12 is a cylindrical body with a tapered taper, and the tip side end inner circumferential surface is a fitting female portion 12a. The fitting female portion 12a is also a tapered surface with a smaller diameter toward the tip side.

この嵌合雌部１２ａに該当する元上竿１２の穂先側端部の内周面は、ポリエステル等の不織布に合成樹脂を含浸させた不織布プリプレグから形成されている。具体的には、元上竿１２を以下のような手法により製造することで、嵌合雌部１２ａに不織布が積層されることになる。即ち、まず、上述の不織布プリプレグを所定のテーパを施した芯材の穂先側端部にのみ巻回する。続いて、周方向若しくは軸方向に炭素繊維などの強化繊維が配向されたうえで合成樹脂が含浸されている周方向若しくは軸方向プリプレグを、芯材及び不織布プリプレグの外周に巻回する。必要に応じて芯材の穂先側端部若しくは竿元側端部に補助用のプリプレグも巻回する。そして、これらを焼成し、芯材を引き抜く。   The inner peripheral surface of the tip side end portion of the former upper collar 12 corresponding to the fitting female portion 12a is formed from a nonwoven fabric prepreg in which a nonwoven fabric such as polyester is impregnated with a synthetic resin. Specifically, the non-woven fabric is laminated on the fitting female portion 12a by manufacturing the original upper collar 12 by the following method. That is, first, the above-mentioned nonwoven fabric prepreg is wound only on the tip end portion of the core material having a predetermined taper. Subsequently, a circumferential or axial prepreg in which reinforcing fibers such as carbon fibers are oriented in the circumferential direction or the axial direction and then impregnated with a synthetic resin is wound around the outer periphery of the core material and the nonwoven fabric prepreg. If necessary, an auxiliary prepreg is also wound around the tip end or the heel end of the core. And these are baked and a core material is extracted.

一方、中竿１３も元上竿１２と同様に先細りテーパの施された筒状体である。もっとも、竿元側端部においては、他の隣接する部分より一段大径化した太径部分１３ａが形成されている。この太径部分１３ａは軸方向において径の変化しない部分若しくは極めて緩い１／１０００程度の傾斜が軸方向に施されている。即ち、嵌合雌部１２ａのテーパより大径部分１３ａのテーパが小さなものとなっていれば足りる。緩やかなこの太径部分１３ａの外径は、図４に示すように、元上竿１２の穂先側端部より幾分竿元側に入り込んだ軸方向位置での元上竿１２の内径に合致するように設定される。即ち、太径部分１３ａの穂先側端部の周縁が元上竿１２の嵌合雌部１２ａに周状に接触するように設定されている。この点は、第１実施形態と同様である。   On the other hand, the middle collar 13 is also a cylindrical body with a tapered taper like the former collar 12. However, a large-diameter portion 13a that is one step larger in diameter than other adjacent portions is formed at the heel side end. The large-diameter portion 13a is provided with a portion in which the diameter does not change in the axial direction or an extremely gentle inclination of about 1/1000 in the axial direction. That is, it is sufficient if the taper of the large diameter portion 13a is smaller than the taper of the fitting female portion 12a. As shown in FIG. 4, the loose outer diameter of the large-diameter portion 13 a matches the inner diameter of the former upper collar 12 at the axial position that is slightly intruded from the tip side end of the former upper collar 12. Set to do. That is, the peripheral edge of the end portion on the tip side of the large-diameter portion 13a is set so as to contact the fitting female portion 12a of the upper collar 12 in a circumferential shape. This is the same as in the first embodiment.

この太径部分１３ａの竿元側の周面には複数のリブ２０が形成されている。リブ２０は、スクリーン印刷によって形成されている。もっとも、第１実施形態と同様に、別途成型した合成樹脂部材などを貼り付けて形成してもよい。この２本のリブ２０が太径部分１３ａの竿元側端縁から螺旋状に相互に交差しながら軸方向に延びている。このリブ２０は竿元側ほど高さが高くなるように、軸方向に於いて傾斜している。即ち、リブ２０の傾斜は、元上竿１２の嵌合雌部１２ａのテーパに合わせて設定されている。   A plurality of ribs 20 are formed on the circumferential surface on the base side of the large diameter portion 13a. The rib 20 is formed by screen printing. However, as in the first embodiment, a separately molded synthetic resin member or the like may be attached. The two ribs 20 extend in the axial direction while spirally intersecting from the base side edge of the large-diameter portion 13a. The rib 20 is inclined in the axial direction so that its height increases toward the base side. That is, the inclination of the rib 20 is set in accordance with the taper of the fitting female portion 12a of the upper collar 12.

なお、ここでは、元上竿２と中竿３とにおいて、両者の連結部分を説明しているが、他の竿体に於いても同様の構造を採用する。その他の構造は第１実施形態と同様である。
このように構成された釣竿でも、中竿１３の竿元側の部分が、その竿元側に隣接する元上竿１２の穂先側の内周面に対して、穂先側で周状に且つ竿元側で螺旋状に接触することで、竿体同士の固着を防止しつつ充分な嵌合力を演出している。軸方向に離れた部位で中竿１３と元上竿１２とが接触し嵌着することで、不要な固着が生じにくく、且つ、十分な嵌合力を演出できる。 In addition, although the connection part of both is demonstrated here in the former collar 2 and the middle collar 3, the same structure is employ | adopted also in another housing. Other structures are the same as those of the first embodiment.
Even in a fishing rod constructed in this way, the heel side portion of the middle rod 13 has a circumferential shape on the tip side with respect to the inner peripheral surface of the heel side of the former upper rod 12 adjacent to the heel side. By contacting in a spiral manner on the original side, a sufficient fitting force is produced while preventing sticking of the casings. Since the middle collar 13 and the former upper collar 12 come into contact with each other and are fitted in a portion separated in the axial direction, unnecessary sticking hardly occurs and sufficient fitting force can be produced.

［他の実施形態］
（ａ）さらに、図５に別の実施形態における元上竿２２と中竿２３との連結部分を示す。この元上竿２２と中竿２３とは第２実施形態と同種のものであるが、中竿２３の竿元側端部の太径部分２３ａのリブ３０は、１つのリブ３０が太径部分２３ａの竿元側端縁から螺旋状に軸方向に延びている。このようなリブ３０は、例えば、マスキング部材を太径部分２３ａの周面に貼り付けた上で、塗料を吹き付けてリブ３０部分を形成し、マスキング部材を剥離し、リブ３０の周面を研磨して径を調整することで形成できる。 [Other Embodiments]
(A) Furthermore, the connection part of the upper collar 22 and the middle collar 23 in another embodiment is shown in FIG. The upper collar 22 and the middle collar 23 are of the same type as in the second embodiment, but the rib 30 of the large-diameter portion 23a at the collar-side end of the middle collar 23 has one rib 30 having a larger diameter. It extends in the axial direction spirally from the base side edge of 23a. Such a rib 30 is formed by, for example, applying a masking member to the peripheral surface of the large-diameter portion 23 a and then spraying paint to form the rib 30 portion, peeling the masking member, and polishing the peripheral surface of the rib 30. Then, it can be formed by adjusting the diameter.

このような螺旋状のリブ３０を形成すると、元上竿２２・中竿２３を相互に連結する際に、各竿体を軸方向に強く引っ張って過剰な負荷をかけても、その負荷が周方向に散らされ固着がさらに生じ難くなる。
（ｂ）上述の各実施形態では、中通し竿を例に説明しているが、これに限定されるものではない。また、釣竿以外のものであっても、筒状体同士を振出形式に連結するもの、例えば、玉網の柄等に本件発明を適用することも可能である。
（ｂ）リブの数や形状は、上記実施形態に限定されるものではなく、適宜変更可能である。 When such a spiral rib 30 is formed, even when the upper collar 22 and the middle collar 23 are connected to each other, even if an excessive load is applied by strongly pulling each chassis in the axial direction, the load is not reduced. It is scattered in the direction and sticking is less likely to occur.
(B) In each of the above-described embodiments, the description has been given by taking the punch through as an example, but the present invention is not limited to this. Moreover, even if it is things other than a fishing rod, it is also possible to apply this invention to the thing which connects cylindrical bodies to a swing-out form, for example, the handle of a ball net, etc.
(B) The number and shape of the ribs are not limited to the above embodiment, and can be changed as appropriate.
