Description

【０００１】
【発明の属する技術分野】
本発明は、並継形式に連結される竿体を嵌合する嵌合構造に関する。
【０００２】
【従来の技術】
従来の並継形式の釣竿は、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、従来の並継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の元竿は、穂先側端部内周面に他の部分よりやや小径に形成され元上竿の竿元側端部を嵌合固定可能な第１嵌合固定部と、竿元側端部内に配置され元上竿の竿元側端部を嵌合固定可能な第２嵌合固定部とを有している。そして、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）と元上竿が元竿内に挿入された状態（以下「収納状態」という）とで、元上竿は第１嵌合固定部と第２嵌合固定部とにそれぞれ嵌合固定される。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、状況に応じて竿全体の長さを変化させて釣りを行える。
【０００４】
【発明が解決しようとする課題】
従来の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では、元竿の第１嵌合固定部，第２嵌合固定部にそれぞれ元上竿自体の竿元側端部外周面を嵌合させて、元竿と元上竿とを固定している。このように、元上竿の竿元側端部は、延伸状態のみでなく収納状態でも嵌合固定用に用いられるため、長期にわたって使用していると嵌合力が低下してしまう恐れがある。
【０００５】
本発明の課題は、長期にわたって嵌合力を十分に維持可能な竿体の嵌合構造を提供することにある。
【００１０】
【課題を解決するための手段】
発明１に係る竿体の嵌合構造は、筒状の第１竿体と第１竿体の穂先側に連結される第２竿体とを嵌合し固定するための嵌合構造であって、前記第１竿体の竿元側端部に脱着自在にはめ込まれた尻栓と、尻栓に連結され第１竿体内部に配置された嵌合雌部と、前記第２竿体の竿元側端部に脱着自在に連結され嵌合雌部に嵌合可能な嵌合雄部とを備え、嵌合雌部は竿体の周方向に並んで配置され前記穂先側軸方向に突出した複数の突出部を有し、嵌合雄部は突出部に嵌着自在な柱状部を有し、周方向に並んで配置された複数の突出部を径内方向に付勢する付勢部材をさらに備えたことを特徴とする。
【００１１】
この場合には、第２竿体を第１竿体の穂先側に引き出した延伸状態においては、通常の並継竿のように、第２竿体の竿元側外周面を第１竿体の穂先側内周面に嵌合させて固定する。そして、第２竿体を第１竿体内に挿入した収納状態においては、第２竿体の竿元側に連結された嵌合雄部を嵌合雌部に嵌合させて固定する。このように、第２竿体と第１竿体とが嵌合する部分が延伸状態と収納状態とにおいて異なるので、長期にわたって使用しても第１竿体と第２竿体との嵌合固定力は低下しにくい。また、嵌合雄部及び嵌合雌部は交換可能であり、仮に嵌合力が低下してもこの嵌合雄部及び嵌合雌部を交換することで、再び十分な嵌合力を演出できる。
また、この場合には、収納状態において、周方向に並んで配置された突出部に囲まれた部分に柱状部が挿入され、突出部に嵌着して係止される。
さらに、この場合には、付勢手段が複数の突出部を径内方向（周方向に並んで配置された突出部の周内方向）に付勢し、突出部に嵌着される柱状部をさらに強固に係止する。
【００１２】
発明２に係る竿体の嵌合構造は、発明１の構造であって、付勢部材は弾性リングである。
【００１３】
この場合には、突出部上にはめ込まれた弾性リングが複数の突出部を径内方向に付勢する。
【００１４】
発明３に係る竿体の嵌合構造は、発明１の構造であって、付勢部材は径内方向への付勢力を調整可能な付勢力調整手段をさらに備えている。
【００１５】
この場合には、長期にわたって使用して突出部の柱状部に対する嵌合力が低下した際に、付勢力調整手段によって突出部の径内方向への付勢力を調整して、嵌合力を調整可能である。
【００２０】
【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。
【００２１】
本発明の第１実施形態を採用した中通し竿は、図１に示すように、元竿１と、元竿１の穂先側に連結された元上竿２と、元上竿２の穂先側に連結された第１中竿３，第２中竿４と、第２中竿４の穂先側に連結された穂先竿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、内部に釣糸通路を有する。そして、第１中竿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になっており、いわゆる振出形式で連結されている。
【００２２】
元竿１は、外周面に形成されリール７を脱着自在に装着可能なリールシート８とを有し、竿元側端部には尻栓１０が脱着自在に装着されている。また、元上竿２には、穂先側外周面に形成されリール７からの釣糸Ｌを竿体内部に導入する釣糸導入孔９が形成されて、釣糸導入孔９を覆うように配置された釣糸ガイドＧが固定されている。穂先竿５の穂先側端部にはトップガイド６が取り付けられており、リール７からの釣糸Ｌは釣糸ガイドＧ及び釣糸導入孔９を通り釣糸通路１００に導かれて、穂先側のトップガイド６より外部へ導かれる。
【００２３】
図２〜４に示すように、元竿１は、やや先細りのテーパが形成された筒状の本体部１ａと、本体部１ａの竿元側端部内周面に形成されたねじ部１ｂとを有している。また、通常の並継ぎ竿と同様に、穂先側端部内周面は他の部分よりやや肉厚に形成され内径が小径になるように成形されており（図示せず）、延伸状態においてこの穂先側端部が元上竿２の竿元側端部外周面と嵌合する。
【００２４】
尻栓１０は、元竿１のねじ部１ｂに脱着自在に螺合され装着された栓部材であって、合成樹脂，合成弾性部材等で形成されている。そして、嵌合雌部１１がこの尻栓１０の穂先側に連結されて元竿１の竿元側内部に配置されている。嵌合雌部１１は、尻栓１０に接着又は溶着された円盤状の本体部１２と、本体部１２の穂先側端面上に竿体の軸方向に突出した４つの突出部１３とを有している。そして、突出部１３には金属リング１４がはめ込まれている。
【００２５】
この４つの突出部１３は、本体部１２と一体的に形成された合成樹脂またはアルミニウム，ステンレス，チタン，スチール若しくはこれらの合金から形成された部材であって、図４に詳しく示すように、本体部１２の穂先側面上に周方向に並んで断面円を描くように均等の間隔を隔てて配置されている。この突出部１３が描く断面円は、その内径が後述する柱状部１５ａの径とほぼ一致するようになっている。４つの柱状部１３の穂先側の外周側の一部はそれぞれ切り欠かれて切欠部１３ａとなっており、この切欠部１３ａに金属リング１４がはめ込まれている。
【００２６】
金属リング１４は、図３に詳しく示すように、突出部１３が形成する断面方向の円に合致するように形成されたリング状部材であり、例えば、形状記憶性を有する超弾性金属等で形成される。金属リング１４の両端部はリングの径外方向に折り曲げられており、それぞれ貫通孔が形成されている。そして、この貫通孔を連結するようにボルト１４ａが配置され、ボルト１４ａの貫通孔への螺合の程度を調整することによって金属リング１４の径を調整可能になっている。
【００２７】
一方、図２に示すように、元上竿２も、元竿１と同様に、やや先細りのテーパが形成された筒状の本体部２ａと、本体部２ａの竿元側端部内周面に形成されたねじ部２ｂとを有している。また、通常の並継ぎ竿と同様に、竿元側端部外周面は、延伸状態において元竿１の穂先側内周面と嵌合する。そして、このねじ部２ｂに嵌合雄部１５が螺合して脱着自在に固定されている。この嵌合雄部１５は、合成樹脂等で形成された略円筒状の部材であって、竿元側には他の部分よりやや小径で竿元側に突出した柱状部１５ａを有している。柱状部１５ａは、嵌合雌部１１の突出部１３の断面円の内径にほぼ一致している。
【００２８】
このように構成された中通し竿では、穂先竿５から順次竿元側の竿体内に挿入していわゆる振出形式で各竿体を収納可能であると共に、元竿１と元上竿２とは、元上竿２を穂先側に引き出した状態（延伸状態）及び元上竿２を元竿１の竿元側まで挿入し収納した状態（収納状態）のいずれの状態においても、互いにその位置を固定可能である。そして、竿全体の長さを変化させて状況に応じて釣りを行う。具体的には、延伸状態においては、通常の並継形式と同様に、元上竿２の竿元側外周面を元竿１の穂先側内周面に嵌合させて固定する。一方、収納状態においては、元上竿２の竿元側に連結された嵌合雄部１５の柱状部１５ａを元竿１の嵌合雌部１１の突出部１３に嵌合させて固定する。
【００２９】
以上のように、元上竿２と元竿１とが嵌合する部分が延伸状態と収納状態とにおいて異なるので、長期にわたって使用しても元上竿２と元竿１との嵌合固定力は低下しにくい。また、嵌合雄部１５及び嵌合雌部１１は交換可能であり、仮に嵌合力が低下してもこの嵌合雄部１５及び／または嵌合雌部１１を交換することで足りる。また、金属リング１４のボルト１４ａを調整することで突出部１３の柱状部１５ａに対する嵌合力を調整可能であり、この嵌合力の調整のみでも長期にわたって十分な嵌合力を演出できる。
［第２実施形態］以下、本発明の第２実施形態について、図面を参照しつつ説明する。
【００３０】
本発明の第２実施形態を採用した中通し竿は、第１実施形態と同様に、元竿１と、元竿１の穂先側に連結された元上竿２と、元上竿２の穂先側に連結された第１中竿３，第２中竿４と、第２中竿４の穂先側に連結された穂先竿５とを有している。そして、第１中竿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になっており、いわゆる振出形式で連結されている。
【００３１】
図５に示すように、元竿１は、やや先細りのテーパが形成された筒状の本体部１ａと、本体部１ａの竿元側端部内周面に形成されたねじ部１ｂとを有している。また、通常の並継ぎ竿と同様に、穂先側端部内周面は他の部分よりやや肉厚に形成され内径が小径になるように成形されており（図示せず）、延伸状態においてこの穂先側端部が元上竿２の竿元側端部外周面と嵌合する。
尻栓２０は、元竿１のねじ部１ｂに脱着自在に螺合され装着された栓部材であって、合成樹脂，合成弾性部材等で形成されている。そして、嵌合雌部２１がこの尻栓２０の穂先側に連結されて元竿１の竿元側内部に配置されている。この嵌合雌部２１は、尻栓２０に接着又は溶着されており、穂先側が開口し内部に空間が形成された筒状部材である。開口した内部に形成された空間が後述の嵌合雄部２２が挿入され嵌着される収納部２１ｂとなっている。収納部２１ｂの穂先側内周面には径内方向に突出した突起部２１ａが形成されている。
【００３２】
一方、元上竿２も、元竿１と同様に、やや先細りのテーパが形成された筒状の本体部２ａと、本体部２ａの竿元側端部内周面に形成されたねじ部２ｂとを有している。また、通常の並継ぎ竿と同様に、竿元側端部外周面は、延伸状態において元竿１の穂先側内周面と嵌合する。そして、このねじ部２ｂに嵌合雄部２２が螺合して脱着自在に固定されている。この嵌合雄部２２は、合成樹脂等で形成された略円筒状の部材であって、嵌合雄部２２の外径は嵌合雌部２１の収納部２１ｂの内径にほぼ一致している。また、嵌合雄部２２の外周面の所定に位置には嵌合雌部２１の突起部２１ａが係止可能な係止溝２２ａが形成されている。
【００３３】
このように構成された中通し竿では、穂先竿５から順次竿元側の竿体内に挿入していわゆる振出形式で各竿体を収納可能であると共に、元竿１と元上竿２とは、元上竿２を穂先側に引き出した状態（延伸状態）及び元上竿２を元竿１の竿元側まで挿入し収納した状態（収納状態）のいずれの状態においても、互いにその位置を固定可能である。そして、竿全体の長さを変化させて状況に応じて釣りを行う。具体的には、延伸状態においては、通常の並継形式と同様に、元上竿２の竿元側外周面を元竿１の穂先側内周面に嵌合させて固定する。一方、収納状態においては、元上竿２の竿元側に連結された嵌合雄部２２を元竿１の嵌合雌部２１の収納部２１ｂに嵌合させて固定する。ここで、突起部２１ａが係止溝２２ａに係止される。
【００３４】
以上のように、元上竿２と元竿１とが嵌合する部分が延伸状態と収納状態とにおいて異なるので、長期にわたって使用しても元上竿２と元竿１との嵌合固定力は低下しにくい。また、嵌合雄部２２及び嵌合雌部２１は交換可能であり、仮に嵌合力が低下してもこの嵌合雄部２２及び／または嵌合雌部２１を交換することで足りる。

BACKGROUND OF THE INVENTION
The present invention relates to a fitting structure that fits a casing that is connected in a cascade manner.
[0002]
[Prior art]
In a conventional series-type fishing rod, a plurality of cylindrical rods can be sequentially inserted into the rod-side housing from the tip-side rod body. When fishing, each chassis is pulled out to the tip side sequentially and fitted and fixed to be used as a single chassis. 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.
[0003]
In addition, there is a conventional cascading type fishing rod that has been devised so that fishing can be performed by changing the overall length of the rod. The fishing rod of the fishing rod devised in this way has a first fitting fixing portion that is formed on the inner peripheral surface of the tip side end portion to be slightly smaller in diameter than the other portions and can be fitted and fixed to the fishing rod side end portion of the upper upper rod. And a second fitting / fixing portion which is disposed in the heel side end portion and can fit and fix the heel side end portion of the upper upper heel. And, the state where the former bowl connected to the tip side of the marshal is pulled out to the tip side (hereinafter referred to as “stretched state”) and the state where the former bowl is inserted into the former side (hereinafter referred to as “storage state”) ) And the former upper collar are fitted and fixed to the first fitting and fixing portion and the second fitting and fixing portion, respectively. Thus, the main rod and the upper rod can be fitted and fixed to each other in both the “extended state” and the “stored state”, and fishing can be performed by changing the length of the entire rod according to the situation.

And in the accommodation state which inserted the 2nd housing in the 1st housing, the fitting male part connected with the base side of the 2nd housing is fitted and fixed to a fitting female part. Thus, since the part which a 2nd housing and a 1st housing fit is different in an extending | stretching state and an accommodation state, even if it uses over a long period of time, a 1st housing and a 2nd housing are fixed by fitting. Power is unlikely to decline. Further, the fitting male part and the fitting female part can be exchanged, and even if the fitting force is reduced, sufficient fitting force can be produced again by exchanging the fitting male part and the fitting female part.
Further, in this case, in the housed state, the columnar portion is inserted into a portion surrounded by the protruding portions arranged side by side in the circumferential direction, and is fitted and locked to the protruding portion.
Further, in this case, the urging means urges the plurality of protrusions in the radially inward direction (inner circumferential direction of the protrusions arranged side by side in the circumferential direction), and the columnar part fitted to the protrusions is provided. Furthermore, it locks firmly.
[0012]
Fitting structure of the rod body according to the present invention 2 is a structure of the invention 1, the biasing member is an elastic ring.
[0013]
In this case, the elastic ring fitted on the protrusions urges the plurality of protrusions in the radially inward direction.
[0014]
The fitting structure of the housing according to the invention 3 is the structure of the invention 1 , and the urging member further includes urging force adjusting means capable of adjusting the urging force in the radial direction.
[0015]
In this case, the fitting force can be adjusted by adjusting the urging force in the radially inward direction of the protruding portion by the urging force adjusting means when the fitting force with respect to the columnar portion of the protruding portion is lowered over a long period of time. is there.

On the other hand, the former upper collar 2 also has a cylindrical main body portion 2a formed with a slightly tapered taper, and a threaded portion 2b formed on the inner peripheral surface of the main body side end of the main body section 2a. have. Similarly to the normal side-by-side ridge, the heel side end outer peripheral surface is fitted with the tip side inner peripheral surface of the heel 1 in the extended state. The fitting male portion 22 is screwed into the screw portion 2b and is detachably fixed. The fitting male part 22 is a substantially cylindrical member formed of synthetic resin or the like, and the outer diameter of the fitting male part 22 substantially matches the inner diameter of the storage part 21b of the fitting female part 21. . Further, a locking groove 22 a that can lock the protrusion 21 a of the fitting female portion 21 is formed at a predetermined position on the outer peripheral surface of the fitting male portion 22.

In the through-through tub constructed in this way, each pod can be accommodated in a so-called swing-out form by inserting it into the pod-side casket sequentially from the tip heel 5 and In both of the state where the upper arm 2 is pulled out toward the tip side (stretched state) and the state where the upper arm 2 is inserted and stored up to the base side of the main rod 1 (stored state) It can be fixed. And fishing is performed according to the situation by changing the overall length of the rod. Specifically, in the stretched state, the heel-side outer peripheral surface of the heel 1 is fitted and fixed to the tip-side inner rim of the heel 1 in the same manner as in the normal succession type. On the other hand, in the housed state, the fitting male part 22 connected to the base side of the base upper collar 2 is fitted and fixed to the storage part 21b of the fitting female part 21 of the base bowl 1. Here, the protrusion 21a is locked in the locking groove 22a.
