特開2003−265075号公報(段落番号〔0009〕及び、図2)Japanese Unexamined Patent Publication No. 2003-265075 (paragraph number [0009] and FIG. 2)

上記構成においては、補強パターンを円周方向に一巻きするものや、一巻で強度が不足すると考える場合には複数巻きするものがあった。このように、一巻で強度が不足する場合には複数巻きするが、複数巻きする場合には強度は向上するものの、竿としての重量が増し持ち重りの原因にもなることがあった。   In the said structure, there existed one which winds a reinforcement pattern in the circumferential direction, and a thing wound several times when thinking that intensity | strength is insufficient with one roll. As described above, when one roll is insufficient in strength, a plurality of windings are performed. However, when a plurality of windings are performed, the strength is improved, but the weight as a bag increases and sometimes the weight is increased.

本発明の目的は、適切に竿先端部の強度を向上させながら、重量化を招来しない構成を提供する点にある。   The objective of this invention is providing the structure which does not cause weight increase, improving the intensity | strength of a heel tip part appropriately.

つまり、口巻き補強パターンを巻回するに、巻始め部分の上に巻き終わり部分を重ねるように巻回するので、巻始め部分と巻き終わり部分とが重なっている部位では補強パターンの二プライ分の強度を発揮するものにできるとともに、巻始め部分と巻き終わり部分以外の巻回部分については補強パターンを一プライ巻いただけのものである。
[Action]
In other words, since the winding reinforcement pattern is wound so that the winding end portion overlaps the winding start portion, the portion where the winding start portion and the winding end portion overlap is equivalent to the two plies of the reinforcement pattern. In addition to the winding start portion and the winding end portion, only one ply of the reinforcing pattern is wound.

〔効果〕
したがって、大きな荷重が作用する部分に前記した巻始め部分と巻き終わり部分の重ね合わせ部分を配置することによって、補強パターンの2プライ分の強度で対抗することができるとともに、他の巻回部分は1プライ分で済むので、ニプライ分の重量増を来たすことはない。
このような構成によって、強度を向上させながら、重量増を抑えたものにできる釣り竿を提供できるにいたった。
〔effect〕
Therefore, by arranging the overlapping portion of the winding start portion and the winding end portion in the portion where a large load acts, it is possible to counter the strength of the two plies of the reinforcing pattern, and the other winding portions are Since only one ply is needed, there is no weight increase for the two plies.
With such a configuration, it is possible to provide a fishing rod that can reduce the increase in weight while improving the strength.

請求項2に係る発明の特徴構成は、請求項1に係る発明において、竿体の軸線長さに相当する長さを備えたプリプレグ製のメインパターンに対して、前記メインパターンより軸線長さが短いプリプレグ製の口巻き補強パターンを、前記メインパターンの竿先端部位置において互いに重なり合う状態に巻回して構成してある釣り竿用の竿体において、前記口巻き補強パターンにおける巻終わり部分を巻始め部分の上に重ね合わせてある点にあり、その作用効果は次の通りである。   A characteristic configuration of the invention according to claim 2 is that, in the invention according to claim 1, the axial length of the prepreg main pattern having a length corresponding to the axial length of the housing is longer than that of the main pattern. In a fishing rod housing that is formed by winding a short prepreg mouthpiece reinforcing pattern in a state of overlapping each other at the tip end portion position of the main pattern, the winding end portion of the mouthpiece reinforcing pattern is a winding start portion. The effect is as follows.

〔作用効果〕
つまり、口巻き補強パターンにおける巻終わり部分を巻始め部分の上に重ね合わせる構成により、補強効果を高めながら竿体としての重量増を必要最小限のものに抑える釣り竿を提供できるに至った。
[Function and effect]
In other words, the configuration in which the winding end portion in the mouth-wrapping reinforcing pattern is superposed on the winding start portion can provide a fishing rod that suppresses the weight increase as a rod body while enhancing the reinforcing effect.

請求項3に係る発明の特徴構成は、請求項2に係る発明において、前記口巻き補強パターンの上から外側口巻き補強パターンを巻回するとともに、前記外側口巻き補強パターンにおける巻始め部分と巻終わり部分とを円周上において重ね合わせて構成し、前記内側に位置する口巻き補強パターンにおける巻き始め部分と巻き終わり部分との重ね合わせ部位と、前記外側に位置する口巻き補強パターンにおける巻き始め部分と巻き終わり部分との重ね合わせ部位とを、竿体の軸芯を挟んで互いに反対側の180°位置又は略180°位置に配置してある点にあり、その作用効果は次の通りである。   A characteristic configuration of the invention according to claim 3 is the invention according to claim 2, wherein the outer mouth-wrapping reinforcement pattern is wound from above the mouth-wrapping reinforcement pattern, and the winding start portion and the winding in the outer mouth-wrapping reinforcement pattern are wound. An end portion is overlapped on the circumference, and an overlap portion of the winding start portion and the winding end portion in the inner winding reinforcement pattern located on the inner side and a winding start in the outer winding reinforcement pattern located on the outer side The overlapping part of the part and the winding end part is arranged at the 180 ° position or the substantially 180 ° position opposite to each other across the shaft core of the housing. is there.

〔第2実施形態〕
ここでは、伸縮式の釣り竿Bについて説明する。図示してはいないが、竿先側竿体を竿尻側竿体から引き出した状態で、竿先側竿体の竿尻端部の膨出部を竿尻側竿体の玉口の内周面に圧接させることによって、その引き出し状態に保持するようになっている。図6に示すように、引き出した状態から竿先側竿体10を竿尻側竿体11内に収納した状態で、竿先側竿体10の竿先端部の膨出部10Bが竿尻側竿体11の玉口の内周面11Aに圧接するとともに、竿先側竿体10の竿尻端部の膨出部10Aが竿尻側竿体11の尻端に尻栓7及び竿受止用の座ゴム8とともに配置されているゴム製の嵌合保持体11B内に内嵌合されて、竿先側竿体10の収納状態を保持する構成としてある。
[Second Embodiment]
Here, the telescopic fishing rod B will be described. Although not shown, the bulging part of the butt end of the heel side skeleton is the inner circumference of the butt end of the butt side skeleton in a state where the heel side skeleton is pulled out from the butt end skeleton. By being brought into pressure contact with the surface, the pulled-out state is maintained. As shown in FIG. 6, in the state where the heel side housing 10 is housed in the heel side housing 11 from the pulled out state, the bulging portion 10B of the heel end portion of the heel side housing 10 is The bulging portion 10A of the butt end of the heel side housing 10 is in pressure contact with the inner peripheral surface 11A of the lip of the housing 11, and the butt plug 7 and the heel are received at the butt end of the butt end housing 11. It is configured to be fitted in a rubber fitting holding body 11B arranged together with the seat rubber 8 and to hold the stored state of the tip side casing 10.

このように、伸縮式の釣り竿Bにおいても、図3に示すように、前記した竿尻側竿体11の玉口の構造と同様の構造を採用する。つまり、必ずしも、前記したメインパターン3A、3B、3Cを3枚重ねる必要はないが、少なくともメインパターン3を巻回した後に、その外側に第1口巻き補強パターン4Aと第2口巻き補強パターン4Bとを、巻始め部分4aと巻終わり部分4bとが円周上の横側面部において重なり合うように巻回する。
このように、口巻き補強パターン4A、4Bを巻回することによって、伸縮式釣り竿Aにおいても、竿尻側竿体11の玉口強度を確保することができる。
In this way, the telescopic fishing rod B also employs a structure similar to the structure of the head of the above-described rod-end side rod body 11 as shown in FIG. That is, it is not always necessary to overlap the three main patterns 3A, 3B, and 3C, but after winding the main pattern 3 at least, the first neck reinforcement pattern 4A and the second neck reinforcement pattern 4B are disposed outside thereof. Are wound so that the winding start portion 4a and the winding end portion 4b overlap each other on the lateral side surface portion on the circumference.
Thus, by winding the wrapping reinforcement patterns 4A and 4B, the gullet strength of the heel-side skeleton 11 can be secured even in the telescopic fishing rod A.

〔別実施形態〕
(1) 口巻き補強パターンとして3枚のプリプレグを巻回する構成について説明する。この場合には、前記と同様に、巻き始め部分4aと巻き終わり部分4bを、3枚のプリプレグ全てにおいて重ね合わせる構成を採ると、玉口断面において左右の肉厚が異なってくるので、図4(イ)に示すように、第1口巻き補強パターン4Aと第2口巻き補強パターン4Bとの巻回状態は、前記したものと同様であるが、第2口巻き補強パターン4Bの上から巻く第3補強パターン3Cについては、巻始め部分4cと巻き終わり部分4dとは重ね合わせないで、突き合わせる状態で配置することになる。
このような構成を採ることによって、第1口巻き補強パターン4Aと第2口巻き補強パターン4Bの巻き始め4a、4cと巻き終わり部分4b、4dが重なり合うことによって、3枚のプリプレグであるが、4プライ分の補強効果を確保している。
[Another embodiment]
(1) A configuration in which three prepregs are wound as a wound reinforcement pattern will be described. In this case, similarly to the above, if the configuration in which the winding start portion 4a and the winding end portion 4b are overlapped in all three prepregs, the wall thickness on the right and left in the cross section of the head becomes different. As shown in (a), the winding state of the first and second winding reinforcement patterns 4A and 4B is the same as that described above, but is wound from above the second winding reinforcement pattern 4B. About the 3rd reinforcement pattern 3C, the winding start part 4c and the winding end part 4d do not overlap, but are arrange | positioned in the state of abutting.
By adopting such a configuration, the winding start portions 4a and 4c and the winding end portions 4b and 4d of the first neck winding reinforcement pattern 4A and the second neck winding reinforcement pattern 4B are overlapped to form three prepregs. A 4-ply reinforcement effect is secured.

(2) 口巻き補強パターンとして3枚のプリプレグを巻回する構成については、次ぎのような構成を採ってもよい。この場合には、図4(ロ)に示すように、3枚の補強パターン4A、4B、4Cの巻き始め部分4a、4c、4eと、巻き終わり部分4b、4d、4fとの重ね合わせ部分を、円周方向で120°離間した位置に設けるようにする。このような構成によって、左右両側部分に重ね合わせ部分が位置しないこととなるが、円周方向3箇所に配置した重ね合わせ部分の強度が向上することによって、3枚のプリプレグであるが、4プライ分の補強効果を確保している。 (2) About the structure which winds three prepregs as a wrapping reinforcement pattern, you may take the following structures. In this case, as shown in FIG. 4 (b), the overlapping portions of the winding start portions 4a, 4c and 4e of the three reinforcing patterns 4A, 4B and 4C and the winding end portions 4b, 4d and 4f are formed. In the circumferential direction, it is provided at a position separated by 120 °. With such a configuration, the overlapping portions are not located on the left and right side portions, but the strength of the overlapping portions arranged at three locations in the circumferential direction is improved, so that three prepregs are formed. The reinforcing effect of the minute is secured.

(3) 口巻き補強パターンとして4枚のものを巻回する構成について説明する。このような構成は、玉口強度を向上させるために必要で、大型の竿に適しているものと思われる。図5に示すように、前記した第1口巻き補強パターン4Aと、第2口巻き補強パターン4Bとを、巻始め部分4a、4cと巻き終わり部分4b、4dとが重なり合うように巻回したものの上から、第3口巻き補強パターン4Cと第4口巻き補強パターン4Dとを、巻始め部分4e、4gと巻き終わり部分4f、4hとが重なり合うように巻回したもののを重ね合わせて構成する。
第3口巻き補強パターン4Cと第4口巻き補強パターン4Dとの巻始め部分4e、4gと巻き終わり部分4f、4hと、第1口巻き補強パターン4Aと第2口巻き補強パターン4Bとの巻始め部分4a、4cと巻き終わり部分4b、4dとの巻き重ね状態は同一であるが、巻始め部分と巻き終わり部分とが重ね合わされた重ね合わせ部分が円周方向に90°ずれた状態となっている。
(3) A structure in which four wound reinforcement patterns are wound will be described. Such a structure is necessary for improving the strength of the head and seems to be suitable for a large ridge. As shown in FIG. 5, the above-described first neck winding reinforcement pattern 4A and the second neck winding reinforcement pattern 4B are wound so that the winding start portions 4a and 4c and the winding end portions 4b and 4d overlap each other. From the top, the 3rd mouth-wrapping reinforcing pattern 4C and the 4th mouth-wrapping reinforcing pattern 4D are formed by overlapping the winding start portions 4e, 4g and the winding end portions 4f, 4h.
Winding of winding start portions 4e and 4g and winding end portions 4f and 4h of the third neck winding reinforcement pattern 4C and the fourth neck winding reinforcement pattern 4D, and the first neck winding reinforcement pattern 4A and the second neck winding reinforcement pattern 4B The overlapping states of the start portions 4a and 4c and the winding end portions 4b and 4d are the same, but the overlapping portion where the winding start portion and the winding end portion are overlapped is shifted by 90 ° in the circumferential direction. ing.

このような構成によって竿体の上下左右の4箇所に巻重ねて強化された部分を配置できて、左右横側部と直交する位置の上下位置においても補強効果を持たせることができ、このことによって上下方向への変形度合いが少なくなり、左右への荷重負担を軽減できる。
また、円周方向4箇所に重ね合わせ部分を設けることとなったので、前記した実施形態のように、円周方向の2箇所においてのみ重ね合わせ部分を設ける場合のように、その重ね合わせ部分を左右の横側部に設定するために目印を竿体に印す等の細かい工夫を採用する必要性は少ない。
With such a configuration, it is possible to arrange the strengthened portions by winding up and down at four places on the top, bottom, left and right of the housing, and it is possible to have a reinforcing effect even at the top and bottom positions perpendicular to the left and right lateral sides. Therefore, the degree of deformation in the vertical direction is reduced, and the load on the left and right can be reduced.
In addition, since the overlapping portions are provided at four places in the circumferential direction, the overlapping portions are provided as in the case where the overlapping portions are provided only at two places in the circumferential direction as in the above-described embodiment. There is little need to adopt fine ideas such as marking on the frame in order to set the left and right sides.

(4) インロー継式の釣り竿Cに適用する場合を説明する。図7に示すように、竿先側竿体12の竿尻端から係合突部12Aを延出するとともに、竿尻側竿体13の竿先端部に前記係合突部12Aを内嵌合する係合孔13Aを形成し、前記係合突部12Aが係合孔13Aに内嵌合して、竿先側竿体12を竿尻側竿体13に嵌合連結保持するように構成してある。
このようなインロー継式の釣り竿Cにおいて、竿尻側竿体13の玉口部の構成としては、第1実施形態、第2実施形態と同様に、図3に示すような、口巻き補強パターン4A、4Bを巻回してある。つまり、マンドレルに対して第1メインパターン3、第2メインパターン3、第3メインパターン3を順番に巻回するとともに、第3メインパターン3の上から、口巻き補強パターン4A、4Bを、巻始め部分4a、4cと巻き終わり部分4b、4dとが重なり合うように巻回してある。このような構成によって、竿尻側竿体13の玉口部の強度を向上させることができる。なお、竿尻側竿体13の玉口部の内周面には係合孔13Aを構成する内向きに膨出する膨出部13aが形成してあるので、この膨出部13aを形成するために、第1メインパターン3の更に内側に図示してはいないが内側口巻き補強パターンを設ける必要がある。
以上のような構成のものは並継式釣り竿に適用してもよい。
(4) A case where the present invention is applied to a spigot type fishing rod C will be described.
