Description

本発明は、穂先竿及びその製造方法に関する。   The present invention relates to a spike candy and a method for producing the same.

穂先竿としては、中実棒状の竿先側部材とその竿先側部材を連結固定する中空状の竿元側部材とからなるものがある（特許文献１参照）。   One type of scissors includes a solid bar-shaped scissors side member and a hollow scissors side member that connects and fixes the scissors side member (see Patent Document 1).

特開２００５−２７５９３号公報（公報段落番号〔０００３〕、〔０００５〕、〔００２３〕、図３〜図６）JP-A-2005-27593 (publication paragraph numbers [0003], [0005], [0023], FIGS. 3 to 6)

上記したように、中実棒状の竿先側部材を採用するのは、魚が掛かった場合の反応の良さと軽量化とを両立させるものである。しかし、竿先側が中実棒状体であり、竿元側が中空状部材であるために、両者の連結構造に種々の工夫が凝らされているが、それでも、次ぎのような問題があった。
つまり、前記した公報の図６に示すように、竿元側部材の先端開口部に竿先側部材の竿元端を嵌合させる嵌合面を削り加工するために、プリプレグからなる補助パターンを削り代として先端開口内周面に装着していたが、竿元側部材の竿先端の外周面が盛り上がりを生じたり、その補助パターンの外側に巻き付けたメインパターンに段差部分ができて、その段差部分での皺が発生する等の問題があった。
また、補助パターンを竿先側に設けているので、竿元側部材の竿先端の外周面に盛り上がりを生じるところから、竿先側部材を竿元側部材に連結固定した際に、その連結部位において、公報の図２で示すように、竿先側部材と竿元側部材との夫々の外周面との間に段差が形成されることになる。そこで、その段差部分を埋めるために、塗料等を厚めに施して被覆する構成を採っていた。
そうすると、この塗料の塗布により、その塗布した部分に盛り上がりを生ずることになり、デザイン上違和感が生ずるものであり、かつ、塗料を塗布する修正作業のような工程が必要となる欠点があった。 As described above, the use of a solid rod-shaped heel-side member achieves both good reaction and weight reduction when a fish is caught. However, since the heel side is a solid rod-like body and the heel side is a hollow member, various contrivances have been devised in the connection structure between them, but there are still the following problems.
That is, as shown in FIG. 6 of the above-mentioned publication, an auxiliary pattern made of a prepreg is formed to cut the fitting surface for fitting the heel end of the heel side member to the tip opening of the heel side member. Although it was mounted on the inner peripheral surface of the tip opening as a cutting allowance, the outer peripheral surface of the heel tip of the heel side member was raised, or a step was formed on the main pattern wound around the auxiliary pattern. There was a problem that wrinkles occurred in the part.
In addition, since the auxiliary pattern is provided on the heel side, when the heel side member is connected and fixed to the heel side member from the rise of the outer peripheral surface of the heel tip of the heel side member, the connecting portion As shown in FIG. 2 of the publication, a step is formed between the outer peripheral surfaces of the heel side member and the heel side member. Therefore, in order to fill the stepped portion, a configuration is adopted in which a thick coating of paint or the like is applied.
In this case, the application of the paint causes swell in the applied part, resulting in a sense of incongruity in design, and there is a drawback that a process such as a correction operation for applying the paint is required.

本発明の目的は、デザイン上の違和感を解消し、塗料を塗布する修正作業のような工程を必要としない穂先竿を提供する点にある。   An object of the present invention is to provide a pointed heel that eliminates a sense of incongruity in design and does not require a process such as a correction operation for applying a paint.

〔構成〕
請求項１に係る発明の特徴構成は、中実棒状の竿先側部材とその竿先側部材に連結固定される中空状の竿元側部材とからなり、前記竿元側部材の竿先端の内周面に、前記竿先側部材の竿尻端部を内嵌保持するための内向きに突出する内嵌合膨出部を形成している点にあり、その作用効果は次の通りである。 〔Constitution〕
The characteristic configuration of the invention according to claim 1 includes a solid rod-shaped heel-side member and a hollow heel-side member connected and fixed to the heel-side member. The inner peripheral surface is formed with an inner fitting bulging portion that protrudes inward to hold the end of the heel end of the tip side member, and the operation and effects thereof are as follows. is there.

〔作用〕
つまり、竿元側部材の竿先端の内周面に、竿先側部材の竿元端を内嵌合するための削り代を確保する手段として、内向きに膨出する内嵌合膨出部を形成した。これによって、この膨出部分に対して竿先側部材の竿元端を嵌合する為の研削処理を施すことができるとともに、内向きに膨出する構成を採ったので、竿元側部材の外周面が従来のように盛り上がりを生ずることはない。 [Action]
That is, an inner fitting bulging portion that bulges inward as a means for securing a cutting allowance for fitting the heel end of the heel side member into the inner peripheral surface of the heel side member. Formed. As a result, a grinding process for fitting the heel end of the heel-side member to the bulging portion can be performed, and a structure that bulges inward is adopted. The outer peripheral surface does not swell unlike the prior art.

〔効果〕
したがって、竿連結部位の盛り上がりを解消できて、盛り上がりができることによる違和感を解消できるとともに、盛り上がりができたことによる竿先側部材と竿元側部材との段差を解消する為の塗料の塗布等を行う必要がない。 〔effect〕
Therefore, it is possible to eliminate the climax of the heel connection part, to eliminate the sense of incongruity due to the swell, and to apply paint to eliminate the step between the heel side member and the heel side member due to the swell. There is no need to do it.

請求項２に係る発明の特徴構成は、請求項１記載の穂先竿における中空状の竿元側部材の製作方法であって、一方向に引き揃えた強化繊維群に樹脂を含浸させたプリプレグを竿体長に相当する長さに裁断したメインパターンと、前記プリプレグを前記竿体長よりも短い長さに裁断した補助パターンとを形成するとともに前記メインパターンと前記補助パターンとを巻回して筒状体を形成する際に利用する芯金を設け、前記芯金を中間部から元側に掛けて一定の割合で大径化する棒状体に形成するとともに先端部に段付き面を介して先端側程前記内嵌合膨出部の突出量だけ小径化する小径部を形成し、前記小径部に前記補助パターンを巻回するとともにその補助パターンの外周面と前記芯金の前記中間部から元側に掛けての外周面とに亘って前記メインパターンを巻回し、前記中空状の竿元側部材に前記内嵌合膨出部を形成する点にあり、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 a method for producing a hollow heel-side member of the tip heel according to claim 1, wherein a prepreg obtained by impregnating a reinforced fiber group aligned in one direction with a resin is used. A cylindrical body is formed by forming a main pattern cut to a length corresponding to a casing length and an auxiliary pattern by cutting the prepreg to a length shorter than the casing length, and winding the main pattern and the auxiliary pattern. A cored bar used in forming the core is provided, and the cored bar is formed into a rod-like body having a constant diameter by hanging from the intermediate part to the original side, and at the distal end side through a stepped surface. A small-diameter portion that is reduced in diameter by the protruding amount of the inner fitting bulge portion is formed, and the auxiliary pattern is wound around the small-diameter portion, and the outer peripheral surface of the auxiliary pattern and the intermediate portion of the core metal are moved to the original side. Across the outer peripheral surface The main pattern winding, located in the point of forming the inside fitting bulging portions on the hollow rod root side member, the effects thereof are as follows.

〔作用効果〕
つまり、竿元側部材の内嵌合膨出部を形成するのに、補助パターンをメインパターンに先行して芯金に巻回する製作方法を示したが、この方法を採る場合に、芯金の先端側部分に段付き面を介して小径部を形成することとしたので、この小径部に補助パターンを巻回することによって、巻回した補助パターンの外面を芯金の中間部の外面径と段差のできない径に形成することができる。
このような構成によって、補助パターンを芯金に巻回した状態でその外面にメインパターンを巻回しても補助パターンによる盛り上がりが生ずることはない。
以上のように、補助パターンによる削り代を確保するものであっても、芯金の外周面に対する改造を施すことによって、盛り上がりができることによる違和感を解消できるとともに、盛り上がりができたことによる竿先側部材と竿元側部材との段差を解消する為の塗料の塗布等を行う必要がない。 [Function and effect]
In other words, in order to form the inner fitting bulge portion of the heel side member, a manufacturing method in which the auxiliary pattern is wound around the core metal prior to the main pattern has been shown. Since the small-diameter portion is formed on the tip side portion via the stepped surface, by winding the auxiliary pattern around the small-diameter portion, the outer surface of the wound auxiliary pattern becomes the outer surface diameter of the intermediate portion of the cored bar. And can be formed in a diameter where there is no step.
With such a configuration, even if the main pattern is wound around the outer surface in a state where the auxiliary pattern is wound around the metal core, the swell due to the auxiliary pattern does not occur.
As mentioned above, even if it is to secure the machining allowance by the auxiliary pattern, by remodeling the outer peripheral surface of the core metal, the discomfort caused by the rise can be eliminated and the tip side caused by the rise There is no need to apply paint to eliminate the step between the member and the heel side member.

請求項３に係る発明の特徴構成は、前記中実棒状の竿先側部材の竿元端に、請求項２記載の前記内嵌合膨出部内に嵌合連結される小径連結部を形成してある点にあり、その作用効果は次の通りである。   According to a third aspect of the present invention, a small-diameter connecting portion that is fitted and connected to the inner fitting bulging portion according to claim 2 is formed at the base end of the solid rod-like tip side member. The operational effects are as follows.

〔作用効果〕
竿先側部材の竿元端に、請求項２記載の前記内嵌合膨出部内に嵌合連結される小径連結部を形成してあるので、竿先側部材の竿元端の外周面と竿元側部材の竿先端の外周面との接続部位において段差が出来にくく、段差を解消するための塗料の塗布等を必要としない。 [Function and effect]
Since a small-diameter coupling portion that is fitted and connected in the inner fitting bulge portion according to claim 2 is formed at the heel end of the heel side member, the outer peripheral surface of the heel end of the heel side member; It is difficult to make a step at the connecting portion with the outer peripheral surface of the heel tip of the heel side member, and it is not necessary to apply paint or the like to eliminate the step.

並継式または振出式の釣り竿における穂先竿Ａについて説明する。図１に示すように、穂先竿Ａは、中実棒状の竿先側部材１とその竿先側部材１に連結固定される中空状の竿元側部材２とからなる。ここでは、竿先側部材１と竿元側部材２とに外付けの釣り糸ガイド３を備えたもので説明する。   The tip rod A in the parallel or swing type fishing rod will be described. As shown in FIG. 1, the tip heel A includes a solid rod-shaped heel-side member 1 and a hollow heel-side member 2 connected and fixed to the heel-side member 1. Here, a description will be given on the assumption that the tip side member 1 and the tip side member 2 are provided with an external fishing line guide 3.

中実棒状の竿先側部材１について説明する。図１（ロ）に示すように、竿先側部材１は、竿の軸線Ｘ方向に沿って徐々に大径化する円錐棒状のものに形成されるとともに、竿元端近くに形成される最大大径部ａから竿元端側に竿元側程小径化する急傾斜面部１Ａとそのさらに竿元側に円柱状の小径連結部１Ｂとを形成して、竿元側部材２に連結可能に構成してある。   The solid rod-shaped tip side member 1 will be described. As shown in FIG. 1 (b), the heel side member 1 is formed in a conical rod-like shape that gradually increases in diameter along the axis X direction of the heel, and is the maximum formed near the heel end. A steeply inclined surface portion 1A that decreases in diameter from the large-diameter portion a toward the heel end side and a cylindrical small-diameter connecting portion 1B on the heel side thereof are formed, and can be connected to the heel side member 2 It is configured.

一方、中空状の竿元側部材２について説明する。図１（ロ）に示すように、竿元側部材２の竿先端開口部に奥側程小径化する入口急傾斜面部２Ｂを形成するとともに、その入口急傾斜面部２Ｂから更に奥側に向かって小径孔状の内嵌合膨出部２Ａを形成してある。小径孔状の内嵌合膨出部２Ａは一定長さに形成されているだけで、内嵌合膨出部２Ａの竿元側端より更に竿元側には、通常の肉厚を有する竿体部分２Ｃを形成している。   On the other hand, the hollow collar side member 2 will be described. As shown in FIG. 1 (b), an entrance steeply inclined surface portion 2B having a smaller diameter toward the back side is formed at the heel end opening of the heel side member 2, and further from the entrance steeply inclined surface portion 2B further toward the back side. A small-diameter hole-like inner fitting bulging portion 2A is formed. The small-diameter hole-like inner fitting bulging portion 2A is formed only to a certain length, and has a normal thickness on the heel side from the heel side end of the inner fitting bulging portion 2A. A body part 2C is formed.

竿先側部材１の製作方法は次ぎの通りである。図示はしていないが、軸線に沿って束ねたガラス強化繊維の束（５００本〜１０００本）を熱硬化性樹脂液内に潜らせてその樹脂を含浸させた後ダイスより引き抜き所定長さに裁断して中実棒状の部材を形成する。ここで、強化繊維としては炭素繊維等も使用できるが、炭素繊維等に比して弾性率が低く柔軟性の高いガラス繊維を採用する。
このように穂先竿の先端に使用する部材を中実棒状としているのは、魚が掛かった場合に、竿が鋭敏に反応すべく構成する必要があるとともに、竿の先端に設けるものであるために、中実棒状の方が中空状のものに比べて軽量でありながら細径化できるからである。 The manufacturing method of the tip side member 1 is as follows. Although not shown in the figure, a bundle of glass reinforcing fibers (500 to 1000) bundled along the axis is submerged in the thermosetting resin liquid and impregnated with the resin, and then pulled out from the die to a predetermined length. Cut to form a solid bar-like member. Here, although carbon fiber etc. can be used as a reinforced fiber, a glass fiber with a low elasticity modulus and high flexibility compared with carbon fiber etc. is employ | adopted.
The reason why the member used at the tip of the spear is in the form of a solid rod is that it is necessary to configure the spear to react sensitively when fish is hung, and it is provided at the tip of the spear In addition, the solid rod shape can be reduced in diameter while being lighter than the hollow rod.

ただし、剛性が高すぎると急激な魚の引き等に対応できずに折れや割れが発生する虞があるので、靭性を保持する為にガラス繊維を採用する方がよい。
以上のように形成した中実棒状の部材の外周面に対して竿元側程徐々に大径化する円錐状に研削加工を施すとともに、竿元端部に削り加工を施して、竿元側程小径化する急傾斜面部１Ａとそのさらに竿元側に一定の径を有する小径連結部１Ｂとを形成する。 However, if the rigidity is too high, it is not possible to cope with rapid fish pulling and the like, and there is a risk of breakage or cracking. Therefore, it is better to use glass fiber in order to maintain toughness.
Grinding is performed in a conical shape that gradually increases in diameter toward the base side with respect to the outer peripheral surface of the solid rod-shaped member formed as described above, and the base end portion is ground and processed. A steeply inclined surface portion 1A having a smaller diameter and a small-diameter connecting portion 1B having a constant diameter on the base side are formed.

中空状の竿元側部材２の製作方法について説明するが、まず、芯金４の形状について説明する。図２に示すように、棒状の素材より研削加工を施して、先端側から元側に掛けてその外周面を、一定の割合で大径化する棒状体４Ｂに形成するとともに先端部に段付き面４ａを介して竿先側程小径化する小径部４Ａを形成する。   Although the manufacturing method of the hollow collar side member 2 is demonstrated, the shape of the metal core 4 is demonstrated first. As shown in FIG. 2, grinding is performed from a rod-shaped material, and the outer peripheral surface is formed on a rod-like body 4 </ b> B whose diameter is increased at a constant rate from the tip side to the base side, and the tip is stepped. A small diameter portion 4A that decreases in diameter toward the tip side is formed through the surface 4a.

このような芯金４に対して巻き付けられる側のプリプレグパターンについて説明する。図２に示すように、一方向に引き揃えた炭素繊維（又はガラス繊維）等からなる強化繊維ｃ群にエポキシ等の熱硬化性樹脂（又は熱可塑性樹脂）を含浸させてプリプレグを形成する。プリプレグから竿元側部材２として必要な竿の長さに相当する長さに裁断してメインパターン５を形成し、プリプレグから竿に相当する長さよりも短い長さに裁断した補助パターン６を形成する。   The prepreg pattern on the side wound around the cored bar 4 will be described. As shown in FIG. 2, a prepreg is formed by impregnating a reinforcing fiber c group made of carbon fibers (or glass fibers) or the like aligned in one direction with a thermosetting resin (or thermoplastic resin) such as epoxy. The main pattern 5 is formed by cutting from the prepreg to a length corresponding to the length of the reed necessary as the reed side member 2, and the auxiliary pattern 6 is formed by cutting from the prepreg to a length shorter than the length corresponding to the reed. To do.

以上のように形成したメインパターン５と補助パターン６とから中空状の竿元側部材２を形成する。図２に示すように、補助パターン６の強化繊維ｃの方向を円周方向に引き揃える。引き揃えた補助パターン６を芯金４の先端側に形成された小径部４Ａに巻き付ける。この場合に巻付ける回数として２〜３回（所謂２プライから３プライ）巻付けることにする。それによって、十分な肉厚を確保できる。巻付け方は、補助パターン６の一枚で３プライを賄えるパターンに裁断することでもよいが、１回巻のパターンのものを複数枚巻付けるものでもよい。
このように、複数回に亘って補助パターン６を巻付けることによって、芯金４の小径部４Ａが覆われて段付き面４ａが隠される。つまり、小径部４Ａに巻き付けられた補助パターン６の表面と芯金４の中間部外周面とが段差の無い状態となる。 The hollow heel side member 2 is formed from the main pattern 5 and the auxiliary pattern 6 formed as described above. As shown in FIG. 2, the direction of the reinforcing fiber c of the auxiliary pattern 6 is aligned in the circumferential direction. The aligned auxiliary pattern 6 is wound around the small diameter portion 4 </ b> A formed on the distal end side of the cored bar 4. In this case, the winding is performed 2 to 3 times (so-called 2 plies to 3 plies). Thereby, sufficient wall thickness can be secured. The winding method may be to cut into a pattern that can cover 3 plies with one auxiliary pattern 6, or a plurality of one-turn patterns may be wound.
In this way, by winding the auxiliary pattern 6 a plurality of times, the small diameter portion 4A of the cored bar 4 is covered and the stepped surface 4a is hidden. That is, there is no step between the surface of the auxiliary pattern 6 wound around the small diameter portion 4A and the outer peripheral surface of the intermediate portion of the cored bar 4.

次に、メインパターン５を巻き付ける。図２に示すように、メインパターン５として、強化繊維ｃの引き揃え方向を円周方向に設定した内側メインパターン５Ａ、強化繊維ｃの引き揃え方向を軸線方向に設定した中間メインパターン５Ｂ、強化繊維ｃの引き揃え方向を円周方向に設定した外側メインパターン５Ｃを用意する。これらのメインパターン５を、補助パターン６の外周面を含んで芯金４の略全長に亘って巻回する。
メインパターン５を複数巻きした後は、図示していないが、セロファンテープ等で緊縛するとともに、焼成炉で焼成した後に、そのテープを剥離し、所定長さに裁断する。裁断した後には、センタレス研磨機等で所定の外面形状に加工する。つまり、竿元側に掛けて徐々に大径化する筒状体に形成され、所定の塗料や釣り糸ガイド３等を取り付けて竿元側部材２を形成する。 Next, the main pattern 5 is wound. As shown in FIG. 2, as the main pattern 5, an inner main pattern 5A in which the alignment direction of the reinforcing fibers c is set in the circumferential direction, an intermediate main pattern 5B in which the alignment direction of the reinforcing fibers c is set in the axial direction, and reinforcement An outer main pattern 5C in which the alignment direction of the fibers c is set in the circumferential direction is prepared. These main patterns 5 are wound over substantially the entire length of the cored bar 4 including the outer peripheral surface of the auxiliary pattern 6.
After winding a plurality of main patterns 5, although not shown in the figure, they are bound with cellophane tape or the like, and after firing in a firing furnace, the tape is peeled off and cut into a predetermined length. After cutting, it is processed into a predetermined outer shape with a centerless polishing machine or the like. That is, it is formed in a cylindrical body that gradually increases in diameter when hung on the heel side, and a heel side member 2 is formed by attaching a predetermined paint or fishing line guide 3 or the like.

図３（イ）に示すように、上記したような製作方法で竿元側部材２の竿先端内周面には、補助パターン６を巻回したことによる内嵌合膨出部２Ａが設けてあり、竿先側部材１の小径連結部１Ｂを内嵌合すべく構成してある。
なお、センタレス研磨機等で所定の外面形状に加工する段階で、竿先側部材１との連結部を形成する為に、図３（イ）（ロ）に示すように、ドリル等の適当な工具によって内嵌合膨出部２Ａの入口に竿元側程小径化する入口急傾斜面部２Ｂを形成してある。 As shown in FIG. 3A, an inner fitting bulging portion 2A formed by winding the auxiliary pattern 6 is provided on the inner peripheral surface of the heel end of the heel side member 2 by the manufacturing method as described above. Yes, the small diameter connecting portion 1B of the tip side member 1 is configured to be fitted inside.
In addition, in order to form a connecting portion with the tip side member 1 at the stage of processing into a predetermined outer surface shape with a centerless polishing machine or the like, as shown in FIGS.

In addition, it is configured so as to fit from the entrance steeply inclined surface portion 2B of the heel side member 2 to the inner fitting bulging portion 2A. In the case of this internal fitting connection, the connecting structure can be strengthened by applying an adhesive from the entrance steep inclined surface portion 2B to the internal fitting bulging portion 2A.

〔別の実施形態〕
（１） この種の穂先竿Ａを適用する竿としては、外面に釣り糸ガイド３を有していない鮎竿等に使用可能である。 Another embodiment
(1) As a rod to which this kind of tip rod A is applied, it can be used for a rod that does not have the fishing line guide 3 on the outer surface.

（２） 上記したように、竿先側部材１と竿元側部材２とを連結する場合に、入口急傾斜面部２Ｂから内嵌合膨出部２Ａに掛けて接着剤を塗布することについて言及した。これに関連して、図４に示すように、入口急傾斜面部２Ｂから内嵌合膨出部２Ａに掛けて環状溝２ａ又は螺旋溝を形成して、接着剤の保有空間を確保する構成を採っても良い。
尚、このように環状溝２ａ等を形成することによって、竿先側部材１と竿元側部材２との連結部位における断面二次モーメント等の剛性に関係するものを低下させることができる。これによって、魚が掛かった場合の曲げの伝達が円滑になり、この部位での突っ張り感等が解消されることが期待できる。 (2) As described above, when connecting the heel side member 1 and the heel side member 2, mention is made of applying an adhesive from the entrance steeply inclined surface portion 2B to the inner fitting bulging portion 2A. did. In relation to this, as shown in FIG. 4, a configuration is adopted in which an annular groove 2a or a spiral groove is formed from the entrance steeply inclined surface portion 2B to the inner fitting bulging portion 2A to secure an adhesive holding space. You may take it.
In addition, by forming the annular groove 2a and the like in this way, it is possible to reduce those related to the rigidity such as the secondary moment of cross section at the connecting portion between the heel side member 1 and the heel side member 2. As a result, it is expected that the transmission of the bend when the fish is caught becomes smooth, and the feeling of tension at this portion is eliminated.
