Description

釣竿fishing rod
　本発明は、無段階且つ微妙な調節が可能な釣竿に関する。 The present invention relates to a fishing rod that can be adjusted steplessly and delicately.
　従来より釣竿は、ターゲットとする魚の大きさや性質に合わせて、その剛性や撓み量などを選んで使用されるのが一般的である。この剛性や撓み量を調整し、使用状態に合わせて硬さ（剛性）を調節して色々な調子に設定できる釣竿も考案されている（例えば、特許文献１参照。）。 Conventionally, fishing rods are generally used by selecting the rigidity and deflection amount according to the size and nature of the target fish. A fishing rod has also been devised in which the rigidity and the amount of deflection are adjusted and the hardness (rigidity) is adjusted in accordance with the state of use and can be set in various tones (see, for example, Patent Document 1).
　この先行技術文献に開示された釣竿は、竿管内側に釣糸ガイドを配設した中通し釣竿であって、釣糸ガイド又は釣糸ガイドを支持する支持体を円周方向に剛性の異なるように形成し、釣糸ガイド又は支持体の円周方向における位置を調節することで、竿管の剛性を調節可能としている。 The fishing rod disclosed in this prior art document is a continuous fishing rod having a fishing line guide disposed on the inner side of the rod tube, and a fishing line guide or a support that supports the fishing line guide is formed so as to have different rigidity in the circumferential direction. By adjusting the position of the fishing line guide or the support in the circumferential direction, the rigidity of the rod pipe can be adjusted.
特開平８－２８９７０２号公報JP-A-8-289702
　しかしながら、上述した特許文献１に開示された技術では、釣糸ガイド又は釣糸ガイドを支持する支持体の位置を竿管内で調節するものであることから、その操作が煩雑であり、調節に時間がかかるという問題がある。特に、釣竿では、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて竿に必要な剛性や撓み量が刻々と変化することから、瞬時に行える操作性が必要とされるとともに、無段階且つ微妙な調節能力が要求される。 However, in the technique disclosed in Patent Document 1 described above, since the position of the fishing line guide or the support body that supports the fishing line guide is adjusted in the rod, the operation is complicated and the adjustment takes time. There is a problem. In particular, fishing rods require operability that can be done instantly because the rigidity and deflection required for the rod change every moment depending on the size, type and nature of the fish caught, the water surface and underwater conditions, etc. Stepless and delicate adjustment capability is required.
　そこで、本発明は、上記問題に鑑み、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節が可能な釣竿を提供することを目的とする。 Therefore, in view of the above problems, an object of the present invention is to provide a fishing rod that maintains operability capable of instantaneously adjusting the stiffness and the amount of deflection, and allows stepless and fine adjustment.
　上記課題を解決するために、本発明は、内部中空のロッド状をなし、可撓性を有する竿本体と、前記竿本体内の中空に挿入される調節用芯材とを備え、前記調節用芯材は、径方向に作用する撓み変形の中心軸に対する角度に応じて、前記撓みに対する硬度が変化されることを特徴とする釣竿である。 In order to solve the above-mentioned problems, the present invention comprises an inner hollow rod-like shape having flexibility, and an adjustment core material inserted into the hollow inside the flange body. The core material is a fishing rod characterized in that the hardness with respect to the bending is changed according to the angle with respect to the central axis of the bending deformation acting in the radial direction.
　このような本発明によれば、竿本体の中空に、径方向に作用する撓み変形の中心軸に対する角度に応じて硬度が変化する調節用芯材を有しているので、利用者が竿本体の撓み変形の方向を変化させることのみで、調節用芯材の硬度を変化させることができ、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて刻々と変化する竿に必要な剛性や撓み量に追従させることができる。このように、本発明によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 According to the present invention, the hollow body of the bag body has the adjusting core material whose hardness changes according to the angle with respect to the central axis of the bending deformation acting in the radial direction. It is possible to change the hardness of the core material for adjustment only by changing the direction of bending deformation of the fish, and it is necessary for dredging that changes every moment according to the size and type of the fish caught, the nature, the surface of the water and underwater Can follow the rigidity and the amount of bending. As described above, according to the present invention, it is possible to maintain operability capable of instantaneously adjusting the rigidity and the deflection amount, and to perform stepless and delicate adjustment.
　上記発明では、前記竿本体の後端に回転可能に連結され、竿本体内に挿通された調節用芯材を保持するグリップ部をさらに備え、前記グリップ部が回転されることにより、前記調節用芯材の径方向に作用する前記撓み変形の中心軸に対する角度が変化され、撓みに対する硬度が変化されることが好ましい。この場合には、利用者が竿本体に対してグリップ部を回転させることのみで、調節用芯材の硬度を変化させることができ、リールやガイドなどが竿本体に取り付けられているようなときであっても、それらの向きなどを気にすることなく、竿に必要な剛性や撓み量に追従させることができる。 In the above-mentioned invention, a grip portion that is rotatably connected to a rear end of the heel body and holds an adjustment core member inserted into the heel body is further provided, and the grip portion is rotated to rotate the adjustment body. It is preferable that the angle with respect to the central axis of the bending deformation acting in the radial direction of the core material is changed, and the hardness against the bending is changed. In this case, when the user can change the hardness of the adjustment core only by rotating the grip part with respect to the bag body, such as when a reel or a guide is attached to the bag body Even so, it is possible to follow the rigidity and the amount of deflection required for the bag without worrying about their orientation.
　また、他の発明は、内部中空のロッド状をなし、可撓性を有する竿本体と、前記竿本体内の中空に挿入される調節用芯材と、前記竿本体の後端に回転可能に連結され、前記竿本体内に挿通された前記調節用芯材を保持するグリップ部とを備え、前記調節用芯材は、前記グリップ部の回転角度に応じて硬度が変化されることを特徴とする釣竿である。 In another aspect of the present invention, the rod body has a hollow inner shape, and has a flexible rod body, an adjustment core inserted into the hollow of the rod body, and a rear end of the rod body. And a grip portion that holds the adjustment core material inserted and inserted into the bag main body, and the hardness of the adjustment core material is changed according to a rotation angle of the grip portion. It is a fishing rod.
　この発明によれば、竿本体の中空には、グリップ部に保持され、グリップ部の回転角度に応じて硬度が変化する調節用芯材を有しているので、利用者が竿本体に対してグリップ部を回転させることのみで、調節用芯材の硬度を変化させ、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて刻々と変化する竿に必要な剛性や撓み量に追従させることができる。 According to the present invention, the hollow of the heel body has the adjusting core material that is held by the grip portion and changes in hardness according to the rotation angle of the grip portion. Only by rotating the grip part, the hardness of the adjustment core material is changed, and the rigidity and deflection amount necessary for the kite that changes momentarily according to the size, type, nature, surface of the fish and underwater conditions etc. Can be followed.
　なお、上記発明において、前記調節用芯材は、可撓性のある複数のワイヤー状の部材が捩られて構成され、先端が前記竿本体内の先端に固定されていることが好ましい。この場合には、調節用芯材は、撓性のある複数のワイヤー状の部材が捩られ、先端で固定されているので、グリップ部を介して調節用芯材を所定方向に回転させると、ワイヤー状の部材がより捩られて、硬度を高くすることができ、撓み量を小さくすることができる。一方、グリップ部を逆方向に所定回転させてワイヤー状の部材を捩られた状態を解消させることで、調節用芯材の硬度を低くすることができ、撓み量を大きくすることができる。このように、本発明によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 In the above invention, it is preferable that the adjustment core material is formed by twisting a plurality of flexible wire-like members, and the tip is fixed to the tip in the bag main body. In this case, since the adjustment core material is twisted by a plurality of flexible wire-like members and fixed at the tip, when the adjustment core material is rotated in a predetermined direction via the grip portion, A wire-like member is twisted more, hardness can be made high, and the amount of bending can be made small. On the other hand, by rotating the grip portion in the reverse direction for a predetermined time to eliminate the twisted state of the wire-like member, the hardness of the adjusting core material can be lowered and the amount of deflection can be increased. As described above, according to the present invention, it is possible to maintain operability capable of instantaneously adjusting the rigidity and the deflection amount, and to perform stepless and delicate adjustment.
　上記発明において、前記調節用芯材は、可撓性のある棒状の部材の内部に、その長手方向に沿って、且つ中心軸線から偏心されて棒状の偏芯材が配置されていることが好ましい。この場合には、グリップ部を介して調節用芯材を回転させ、偏芯材を、棒状の部材の中心軸を通過し、釣竿を撓らせる方向（以下、単に撓み変形方向という。）と同軸上に配置させることで、調節用芯材の硬度を高くすることができるので、撓み変形方向への撓み量を小さくすることができる。一方、グリップ部を介して調節用芯材を回転させ、偏芯材を撓み変形方向とは異なる軸上に配置させることで、調節用芯材１０の硬度を低くすることができ、撓み変形方向への撓み量を大きくすることができる。このように本発明によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 In the above invention, it is preferable that the adjustment core material is disposed in a flexible rod-shaped member along the longitudinal direction and eccentric from the central axis. . In this case, the adjustment core material is rotated via the grip portion, and the eccentric material passes through the central axis of the rod-shaped member to bend the fishing rod (hereinafter simply referred to as a bending deformation direction). Since the adjustment core material can be increased in hardness by being arranged on the same axis, the amount of bending in the bending deformation direction can be reduced. On the other hand, by rotating the adjusting core material via the grip portion and arranging the eccentric material on an axis different from the bending deformation direction, the hardness of the adjusting core material 10 can be lowered, and the bending deformation direction It is possible to increase the amount of bending. As described above, according to the present invention, it is possible to maintain operability capable of instantaneously adjusting the rigidity and the amount of deflection, and to perform stepless and delicate adjustment.
　上記発明において、前記調節用芯材は、可撓性のある棒状の部材の内部に、その長手方向に沿って、且つ径方向断面が扁平な扁平芯材が配置されていることが好ましい。この場合には、グリップ部を介して調節用芯材を回転させ、扁平芯材の断面長手方向を撓み変形方向と平行にさせることで、調節用芯材の硬度を高くすることができるので、撓み変形方向への撓み量を小さくすることができる。一方、グリップ部を回転させ、扁平芯材の断面長手方向を撓み変形方向と直交にさせることで、調節用芯材の硬度を低くすることができるので、撓み変形方向への撓み量を大きくすることができる。このように本発明によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 In the above invention, it is preferable that a flat core material having a flat radial cross section is disposed along the longitudinal direction of the adjustment core material inside a flexible rod-shaped member. In this case, the hardness of the adjustment core material can be increased by rotating the adjustment core material via the grip portion and making the cross-sectional longitudinal direction of the flat core material parallel to the bending deformation direction. The amount of bending in the bending deformation direction can be reduced. On the other hand, by rotating the grip portion and making the cross-sectional longitudinal direction of the flat core material perpendicular to the bending deformation direction, the hardness of the adjustment core material can be lowered, so the amount of bending in the bending deformation direction is increased. be able to. As described above, according to the present invention, it is possible to maintain operability capable of instantaneously adjusting the rigidity and the amount of deflection, and to perform stepless and delicate adjustment.
　上記発明において、前記調節用芯材は、可撓性のある棒状の部材の側面に、その長手方向に沿って複数の切り込みが形成されていることが好ましい。この場合には、グリップ部を介して調節用芯材を回転させ、切り込みの切込方向を撓み変形方向と平行にさせることで、調節用芯材の硬度を高くすることができるので、撓み変形方向への撓み量を小さくすることができる。一方、グリップ部を回転させ、切り込みの切込方向を撓み変形方向と直交にさせることで、調節用芯材の硬度を低くすることができるので、撓み変形方向への撓み量を大きくすることができる。このように、本発明によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 In the above invention, the adjustment core member is preferably formed with a plurality of cuts along the longitudinal direction on a side surface of a flexible rod-shaped member. In this case, the adjustment core material is rotated through the grip portion, and the incision direction of the incision is made parallel to the bending deformation direction, so that the hardness of the adjustment core material can be increased. The amount of deflection in the direction can be reduced. On the other hand, by rotating the grip portion and making the incision direction of the incision perpendicular to the bending deformation direction, the hardness of the adjusting core material can be lowered, so that the amount of bending in the bending deformation direction can be increased. it can. As described above, according to the present invention, it is possible to maintain operability capable of instantaneously adjusting the rigidity and the deflection amount, and to perform stepless and delicate adjustment.
　以上述べたように、この発明によれば、釣竿において、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節することができることから、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて刻々と変化する竿に必要な剛性や撓み量に追従させることができる。 As described above, according to the present invention, in the fishing rod, it is possible to maintain the operability capable of instantaneously adjusting the rigidity and the amount of deflection, and the stepless and delicate adjustment can be performed. It is possible to follow the rigidity and the amount of deflection required for the dredging that changes momentarily according to the nature, water surface and underwater conditions.

　以下に添付図面を参照して、本発明に係る釣竿の実施形態を詳細に説明する。図１（ａ）及び（ｂ）は、本実施形態に係る釣竿の一部を示す側面図であり、図２は、実施形態に係る調節用芯材を示す斜視図である。 Hereinafter, an embodiment of a fishing rod according to the present invention will be described in detail with reference to the accompanying drawings. FIGS. 1A and 1B are side views showing a part of a fishing rod according to the present embodiment, and FIG. 2 is a perspective view showing an adjusting core material according to the embodiment.
　本実施形態において、釣竿１は、竿本体５と、グリップ部２と、リールシート部３と、リール部６とを備えている。グリップ部２は、実釣時において操作者が把持する部分であって、フロントグリップ部２２及びリアグリップ部２１を備えている。フロントグリップ部２２は、エチレン酢酸ビニル樹脂或いはウレタン樹脂等の柔軟な合成樹脂発泡材料、又はコルク、ゴム、エラストマー等の材料により形成される筒状部材であり、竿本体５の中間部分において、その外周に装着され固定されている。一方、リアグリップ部２１は、内部に硬質合成樹脂や金属部材で形成された円筒状の外周に、フロントグリップ部２２と同様な素材で形成されたカバー部材が貼り合わされて形成されている。このリアグリップ部２１は、の竿本体５の後端において竿本体５に対して回転可能に連結されている。そして、フロントグリップ部２２及びリアグリップ部２１の間にリールシート部３が設けられている。 In this embodiment, the fishing rod 1 includes a rod main body 5, a grip portion 2, a reel sheet portion 3, and a reel portion 6. The grip portion 2 is a portion that is held by an operator during actual fishing, and includes a front grip portion 22 and a rear grip portion 21. The front grip portion 22 is a cylindrical member formed of a flexible synthetic resin foam material such as ethylene vinyl acetate resin or urethane resin, or a material such as cork, rubber, or elastomer. Attached to the outer periphery and fixed. On the other hand, the rear grip portion 21 is formed by bonding a cover member formed of the same material as the front grip portion 22 to a cylindrical outer periphery formed of a hard synthetic resin or a metal member. The rear grip portion 21 is rotatably connected to the heel body 5 at the rear end of the heel body 5. The reel seat portion 3 is provided between the front grip portion 22 and the rear grip portion 21.
　このリールシート部３は、釣用のリール部６を装着・固定するためのものであり、硬質合成樹脂や金属部材で形成される。このリールシート部３には、竿本体５の外周面に固定される略筒状の本体部３１と、本体部３１のリアグリップ部２１側に配置され、リール部６の後脚と係合する固定フード３３と、本体部３１のフロントグリップ部２２側に配置され、リール部６の前脚と係合する移動フード３２とから形成される。 The reel seat portion 3 is for mounting and fixing a fishing reel portion 6 and is formed of a hard synthetic resin or a metal member. The reel seat portion 3 is disposed on the side of the rear grip portion 21 of the main body portion 31 that is fixed to the outer peripheral surface of the bag main body 5 and is engaged with the rear leg of the reel portion 6. The fixed hood 33 and the movable hood 32 which is disposed on the front grip portion 22 side of the main body portion 31 and engages with the front leg of the reel portion 6 are formed.
　本体部３１には、フロントグリップ部２２側において、外周に雄ネジが形成されたネジ部３５を有しているとともに、ネジ部３５には、ネジ部３５に螺着され回転することでネジ部３５上をスライド移動するナット部３４を有している。本実施形態において、ナット部３４は、移動フード３２の穂先側に形成されており、ナット部３４と移動フード３２とを一体移動可能に構成している。 The main body portion 31 has a screw portion 35 having a male screw formed on the outer periphery on the front grip portion 22 side, and the screw portion 35 is screwed into the screw portion 35 and rotated to rotate the screw portion. 35 has a nut portion 34 that slides on the surface 35. In the present embodiment, the nut portion 34 is formed on the tip side of the moving hood 32, and the nut portion 34 and the moving hood 32 are configured to be movable together.
　このため、ナット部３４を所定方向へ回転させると、移動フード３２が本体部３１側へスライドするようになっている。したがって、リールシート部３にリール部６の脚部を載置した状態でナット部３４を回転させることによって、移動フード３２と固定フード３３とによってリール部６の脚部を挟持し、固定することができるようになっている。 Therefore, when the nut portion 34 is rotated in a predetermined direction, the movable hood 32 slides toward the main body portion 31 side. Therefore, the leg part of the reel part 6 is clamped and fixed by the movable hood 32 and the fixed hood 33 by rotating the nut part 34 with the leg part of the reel part 6 placed on the reel sheet part 3. Can be done.
　また、ナット部３４を反所定方向へ回転させることによって移動フード３２を本体部３１と反対側へスライドさせることができるので、リール部６をリールシート部３から取り外すことができる。なお、ナット部３４には、ナット部３４の緩みを防止するロックナットとしての機能も備えている。これらナット部３４の外周面には、滑り止めのためのローレット加工を施すこともできる。また、上述したリールシート部３の構成は一例であり、例えば、移動フードがリアグリップ側にある構成など、種々変更可能である。 Further, since the moving hood 32 can be slid to the opposite side of the main body 31 by rotating the nut portion 34 in the opposite direction, the reel portion 6 can be removed from the reel seat portion 3. The nut portion 34 also has a function as a lock nut that prevents the nut portion 34 from loosening. The outer peripheral surface of these nut portions 34 can be knurled to prevent slipping. In addition, the configuration of the reel seat portion 3 described above is an example, and various modifications such as a configuration in which the moving hood is on the rear grip side can be made.
　リール部６は、リールシート部３に着脱可能に取り付けられ、釣糸を前方に繰り出す部材であり、リール本体６１と、リール本体に軸受によって支持されるスプール６２と、スプールに回転させ、釣糸を巻き取るハンドル６３等を有する一般的なリールであり、片軸受リール、両軸受リール、スピニングリール、電動リールなど種々のリールを用いることができる。本実施形態において、リール部６の両脚部は、リールシート部３に差し込み可能となっている。なお、図示していないが、リール部６に取り付けられた釣糸は、竿本体５の所要の位置に配設されているガイド孔に挿通される。 The reel portion 6 is a member that is detachably attached to the reel seat portion 3 and is a member that feeds a fishing line forward. The reel body 61, a spool 62 supported by a bearing on the reel body, and a spool are rotated to wind the fishing line. The reel is a general reel having a handle 63 and the like, and various reels such as a single bearing reel, a dual bearing reel, a spinning reel, and an electric reel can be used. In the present embodiment, both leg portions of the reel portion 6 can be inserted into the reel seat portion 3. Although not shown, the fishing line attached to the reel unit 6 is inserted into a guide hole provided at a required position of the rod body 5.
　竿本体５は、可撓性を有する細長の棒状部材であり、炭素繊維強化プラスチック（カーボン）やガラス繊維強化プラスチック（グラスファイバ）、ボロン、アラミド繊維、ザイロン繊維等、所定の硬度を有する素材で形成される。なお、竿本体５は、一体的に形成され、竿尻から竿先に向かい竿径がスムーズに小径化する構成であったり、複数個に分割して継ぎにより一体化する継ぎ竿であってもよい。 The heel body 5 is an elongated rod-like member having flexibility, and is made of a material having a predetermined hardness, such as carbon fiber reinforced plastic (carbon), glass fiber reinforced plastic (glass fiber), boron, aramid fiber, and xylon fiber. It is formed. It should be noted that the heel body 5 is formed integrally and has a structure in which the heel diameter is smoothly reduced from the butt to the heel, or a joint that is divided into a plurality of pieces and integrated by joining. Good.
　本実施形態において、竿本体５は、内部中空５３のロッド状をなしており、図１（ｂ）に示すように、竿本体５内の中空５３に調節用芯材１０が挿入されている。調節用芯材１０は、図２に示すように、可撓性のある複数のワイヤー状の部材１１が捩られて構成されている。このワイヤー状部材１１としては、金属や合成樹脂で形成することができる。この調節用芯材１０は、竿本体５内に挿通された状態で、後端がリアグリップ部２１に保持されるとともに、先端が竿本体５内の先端に設けられた固定部５２に固定されている。 In the present embodiment, the rod body 5 has a rod shape with an internal hollow 53, and the adjustment core 10 is inserted into the hollow 53 in the rod body 5 as shown in FIG. As shown in FIG. 2, the adjustment core member 10 is configured by twisting a plurality of flexible wire-like members 11. The wire member 11 can be formed of metal or synthetic resin. The adjustment core 10 is inserted into the bag main body 5, the rear end is held by the rear grip portion 21, and the tip is fixed to a fixing portion 52 provided at the tip of the bag main body 5. ing.
　そして、本実施形態において、リアグリップ部２１は、竿本体５の後端において回転可能に連結されている。具体的に、竿本体５の後端は、ネジ部５１が形成されているとともに、リアグリップ部２１の竿先側には、ネジ部５１と螺着される雌ネジが内表面に形成された係止部２３を有しており、係止部２３をネジ部５１に螺着することで竿本体５とリアグリップ部２１とが連結される。また、リアグリップ部２１と係止部２３とは、例えば、ネジ機構（図示省略）で連結されており、リアグリップ部２１は、係止部２３に対して回転可能となっている。これにより、リアグリップ部２１は、係止部２３と連結された竿本体５に対して回転可能となっている。なお、リアグリップ部２１と係止部２３との連結部分は、一定以上の回転を行った場合であっても空回りするような空回り機構が形成され、取り外し不可能となっている。 And in this embodiment, the rear grip part 21 is rotatably connected at the rear end of the bag body 5. Specifically, a threaded portion 51 is formed at the rear end of the collar body 5, and a female screw that is screwed to the threaded part 51 is formed on the inner surface of the collar side of the rear grip part 21. It has the latching | locking part 23, and the hook main body 5 and the rear grip part 21 are connected by screwing the latching | locking part 23 to the screw part 51. FIG. Moreover, the rear grip part 21 and the latching | locking part 23 are connected with the screw mechanism (illustration omitted), for example, and the rear grip part 21 can rotate with respect to the latching | locking part 23. FIG. Thereby, the rear grip part 21 is rotatable with respect to the bag main body 5 connected to the locking part 23. The connecting portion between the rear grip portion 21 and the locking portion 23 is formed with an idling mechanism that causes idling even when the rotation exceeds a certain level, and cannot be removed.
　このような構成により、リアグリップ部２１が回転されることにより、リアグリップ部２１の回転角度に応じて撓りに対する硬度が調整可能となっている。すなわち、図３（ａ）に示すように、リアグリップ部２１を竿本体５に対して所定角度だけ回転させることで、リアグリップ部２１とともに、その先端が竿本体５に固定された複数のワイヤー状部材１１が捩られる。その結果、捩られた調節用芯材１０の硬度が高くなり、釣竿を撓らせる方向（以下、撓み変形方向Ｌという。）に対する撓み量を小さくすることができる。一方、図３（ｂ）に示すように、リアグリップ部２１を逆方向に所定回転させ、複数のワイヤー状部材１１を捩られた状態を解消させることで、調節用芯材１０の硬度を低くすることができ、撓み変形方向Ｌに対する撓み量を大きくすることができる。 With such a configuration, when the rear grip portion 21 is rotated, the hardness against bending can be adjusted according to the rotation angle of the rear grip portion 21. That is, as shown in FIG. 3 (a), the rear grip portion 21 is rotated by a predetermined angle with respect to the heel body 5, so that a plurality of wires whose tips are fixed to the heel body 5 together with the rear grip portion 21. The member 11 is twisted. As a result, the hardness of the twisted adjusting core member 10 is increased, and the amount of bending with respect to the direction in which the fishing rod is bent (hereinafter referred to as a bending deformation direction L) can be reduced. On the other hand, as shown in FIG. 3B, the hardness of the adjusting core member 10 is lowered by rotating the rear grip portion 21 in a predetermined direction in the reverse direction to eliminate the twisted state of the plurality of wire-like members 11. The amount of bending with respect to the bending deformation direction L can be increased.
　なお、調節用芯材１０は、竿本体５に対して着脱可能となっており、図１（ｂ）に示すように、リアグリップ部２１と竿本体５とを取り外し、リアグリップ部２１及び竿本体５の係止状態を解除することで交換することができる。 The adjustment core 10 is detachable from the heel body 5, and as shown in FIG. 1 (b), the rear grip part 21 and the heel body 5 are removed, and the rear grip part 21 and the heel body 5 are removed. The main body 5 can be exchanged by releasing the locked state.
（作用・効果）
　本実施形態によれば、竿本体５の中空５３には、撓性のある複数のワイヤー状の部材が捩られて構成される調節用芯材１０が備えられ、調節用芯材１０の後端はリアグリップ部２１に固定され、先端は竿本体５の固定部５２で固定されているので、利用者が竿本体５に対して回転可能に連結されているリアグリップ部２１を回転させることのみで、内部の調節用芯材１０を回転させ、調節用芯材の硬度を変化させることができる。 (Action / Effect)
According to the present embodiment, the hollow 53 of the heel body 5 is provided with the adjusting core member 10 formed by twisting a plurality of flexible wire-like members, and the rear end of the adjusting core member 10 Is fixed to the rear grip portion 21 and the tip is fixed by the fixing portion 52 of the heel body 5, so that the user only rotates the rear grip portion 21 that is rotatably connected to the heel body 5. Thus, the internal adjustment core 10 can be rotated to change the hardness of the adjustment core.
　具体的には、リアグリップ部２１を介して調節用芯材１０を所定方向に回転させて、ワイヤー状の部材をより捩って硬度を高くすることで、撓み変形方向Ｌに対する撓み量を小さくすることができる。これにより、操作性を高くすることができるので、フッキング等の操作性を向上させることができるとともに、大きい魚をバラすことなく釣ることができる。 Specifically, by rotating the adjustment core member 10 in a predetermined direction via the rear grip portion 21 and twisting the wire-like member to increase the hardness, the amount of bending with respect to the bending deformation direction L is reduced. can do. Thereby, since operativity can be made high, operativity, such as hooking, can be improved, and it can fish without breaking a big fish.
　一方、リアグリップ部２１を逆方向に所定回転させてワイヤー状の部材を捩られた状態を解消させ、調節用芯材の硬度を低くすることで、撓み変形方向Ｌに対する撓み量を大きくすることができる。これにより、魚が掛かった瞬間の引っ張り力を吸収し、糸切れ等を防ぐことができる。また、小さい魚などを釣る際には張り具合を利用者に適切に伝達することができる。さらに、仕掛けなどを投げる際、その大きな撓み量を利用してより遠くに飛ばすことができる。 On the other hand, by rotating the rear grip portion 21 in the reverse direction a predetermined amount to eliminate the twisted state of the wire-like member and lowering the hardness of the adjusting core material, the amount of bending with respect to the bending deformation direction L is increased. Can do. Thereby, the pulling force at the moment when the fish is caught can be absorbed and thread breakage or the like can be prevented. In addition, when fishing small fish, the tension can be appropriately transmitted to the user. Furthermore, when throwing a device or the like, it is possible to fly farther using the large amount of deflection.
　このように、本実施形態では、リアグリップ部２１を回転させることで、段階的に調節用芯材１０の硬度を変化させることができるので、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて刻々と変化する竿に必要な剛性や撓み量に追従することができる。そのため、本実施形態によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 As described above, in this embodiment, the hardness of the adjustment core member 10 can be changed stepwise by rotating the rear grip portion 21. Therefore, the size, type, and nature of the fish that is hung, It is possible to follow the rigidity and the amount of deflection required for the kite that changes momentarily according to the situation. Therefore, according to the present embodiment, it is possible to maintain the operability capable of instantaneously adjusting the rigidity and the amount of deflection, and to perform stepless and delicate adjustment.

　なお、上述した実施形態の説明は、本発明の一例である。このため、本発明は上述した実施形態に限定されることなく、本発明に係る技術的思想を逸脱しない範囲であれば、設計等に応じて種々の変更が可能である。以下、各変更例について説明する。 [Example of change]
The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to the design and the like as long as they do not depart from the technical idea of the present invention. Hereinafter, each modified example will be described.
　図４（ａ）は、各変更例に係る調節用芯材の外観を示す斜視図である。なお、以下の変更例において、上述した各実施形態と同一の構成要素には同一の符号を付し、その機能等は特に言及しない限り同一であり、その説明は省略する。 FIG. 4A is a perspective view showing the appearance of the adjusting core material according to each modified example. Note that, in the following modification, the same components as those in the above-described embodiments are denoted by the same reference numerals, and the functions and the like are the same unless otherwise specified, and the description thereof is omitted.
　上述した実施形態において、調節用芯材１０は、複数のワイヤー状部材１１を捩った構成としたが、本発明はこれ限定されるものではなく、図４（ａ）に示すような形態を採用することもできる。すなわち、同図（ｂ）に示すように、調節用芯材１０ａとして、径方向に作用する撓み変形Ｐの中心軸Ｃに対する角度θ、言い換えれば、撓み変形Ｐによる曲げ応力の作用方向が、中心軸Ｃを含む所定断面Ｓに対する角度θに応じて、その撓みに対する耐力が変化する部材を用いる。具体的に、本実施形態では、調節用芯材１０ａは、リアグリップ部２１の先端に連結されており、リアグリップ２１の回転に伴って調節用芯材１０ａを撓らせる方向が変化され、その回転角度に応じて、調節用芯材１０ａの径方向に作用する撓み変形の中心軸Ｃに対する角度θが変化され、撓みに対する硬度が変化される。 In the embodiment described above, the adjustment core member 10 has a configuration in which a plurality of wire-like members 11 are twisted. However, the present invention is not limited to this, and has a form as shown in FIG. It can also be adopted. That is, as shown in FIG. 5B, as the adjusting core member 10a, the angle θ with respect to the central axis C of the bending deformation P acting in the radial direction, in other words, the acting direction of the bending stress due to the bending deformation P is the center. A member whose resistance to bending is changed according to the angle θ with respect to the predetermined cross section S including the axis C is used. Specifically, in the present embodiment, the adjustment core member 10a is connected to the tip of the rear grip portion 21, and the direction in which the adjustment core member 10a is bent is changed as the rear grip 21 rotates, According to the rotation angle, the angle θ with respect to the central axis C of the bending deformation acting in the radial direction of the adjusting core member 10a is changed, and the hardness against the bending is changed.
　この棒状の調節用芯材１０ａは、合成樹脂材などの可撓性のある部材から形成されている。そして、調節用芯材１０ａは、以下に示すような各構成を備えることで、リアグリップ部２１の回転角度に応じてこの調節用芯材１０の硬度を変化させることができるようになっている。以下、調節用芯材１０ａの各構成について説明する。 The rod-shaped adjusting core material 10a is formed of a flexible member such as a synthetic resin material. And the adjustment core material 10a can change the hardness of this adjustment core material 10 according to the rotation angle of the rear grip part 21 by providing each structure as shown below. . Hereinafter, each structure of the core material 10a for adjustment is demonstrated.
（変更例１）
　先ず、変更例１について説明する。図５は、変更例１に係る調節用芯材の構成を示す説明図であり、同図（ａ）は斜視図を示し、同図（ｂ）及び（ｃ）は断面図を示している。変更例１に係る調節用芯材１０ａは、図５（ａ）に示すように、合成樹脂など可撓性のある棒状の部材を本体として、その調節用芯材１０ａの内部に設けられ、その調節用芯材１０ａの長手方向に沿って延設される棒状の芯材１３，１４から構成される。 (Modification 1)
First, Modification Example 1 will be described. FIGS. 5A and 5B are explanatory views showing the configuration of the adjusting core material according to the modified example 1. FIG. 5A shows a perspective view, and FIGS. 5B and 5C show cross-sectional views. As shown in FIG. 5 (a), the adjustment core material 10a according to the modified example 1 is provided inside the adjustment core material 10a with a flexible rod-shaped member such as a synthetic resin as a main body. It is comprised from the rod-shaped core materials 13 and 14 extended along the longitudinal direction of the core material 10a for adjustment.
　詳述すると、芯材１３，１４は、調節用芯材１０ａと比較して、剛性で可撓性の低い硬化部材で形成されている。そして、同５（ｂ）及び（ｃ）に示すように、一方の芯材は、中心軸線に沿って形成された芯材１４となっており、他方は中心軸線から偏心された偏芯材１３となっており、この２本の芯材は、相互の位置関係から、径方向に作用する撓み変形Ｐの中心軸Ｃに対する角度θが変化するようになっている。言い換えれば、撓み変形Ｐによる曲げ応力の作用方向の、中心軸Ｃを含む所定断面Ｓに対する角度θに応じて、撓み変形Ｐに対する２本の芯材１３，１４の位置が、縦に並ぶか横に並ぶかが変化されることとなり、その撓みに対する耐力が変化するようになっている。なお、これらの芯材１３及び１４は、同質の素材でもよく、一方を他方よりも硬く（或いは柔らかく）してもよい。 More specifically, the core members 13 and 14 are formed of a hardened member that is less rigid and less flexible than the adjustment core member 10a. As shown in FIGS. 5 (b) and 5 (c), one core material is a core material 14 formed along the central axis, and the other is an eccentric material 13 eccentric from the central axis. The two core members are configured such that the angle θ with respect to the central axis C of the bending deformation P acting in the radial direction changes from the mutual positional relationship. In other words, depending on the angle θ with respect to the predetermined cross section S including the central axis C in the direction of action of the bending stress due to the bending deformation P, the positions of the two core members 13 and 14 with respect to the bending deformation P are aligned vertically or horizontally. The resistance to bending is changed. In addition, these core materials 13 and 14 may be a homogeneous material, and one may be harder (or softer) than the other.
　このような構成により、リアグリップ部２１を介して調節用芯材１０ａを回転させ、図５（ｂ）に示すように、偏芯材１３と中芯材１４とを、撓み変形方向Ｌと同軸上に配置させることで、調節用芯材１０ａの硬度を高くすることができるので、撓み変形方向Ｌへの撓み量を小さくすることができる。一方、図５（ｃ）に示すように、リアグリップ部２１を９０度回転させ、上記θが９０°となるようにして、偏芯材１３と中芯材１４とを撓み変形方向Ｌの軸上とは異なる位置に配置させることで、調節用芯材１０の硬度を低くすることができ、撓み変形方向Ｌへの撓み量を大きくすることができる。 With such a configuration, the adjusting core member 10a is rotated via the rear grip portion 21, and the eccentric member 13 and the intermediate member 14 are coaxial with the bending deformation direction L as shown in FIG. Since the hardness of the adjustment core member 10a can be increased by arranging the upper portion, the amount of bending in the bending deformation direction L can be reduced. On the other hand, as shown in FIG. 5C, the rear grip portion 21 is rotated 90 degrees so that the angle θ is 90 °, and the eccentric material 13 and the core material 14 are bent in the direction of the bending deformation direction L. By disposing at a position different from the above, the hardness of the adjusting core member 10 can be lowered, and the amount of bending in the bending deformation direction L can be increased.
（変更例２）
　次いで、変更例２について説明する。図６は、変更例２に係る調節用芯材の構成を示す説明図であり、同図（ａ）は、斜視図を示し、同図（ｂ）及び（ｃ）は、その断面図である。 (Modification 2)
Next, Modification 2 will be described. 6A and 6B are explanatory views showing the configuration of the adjusting core material according to the modified example 2. FIG. 6A is a perspective view, and FIGS. 6B and 6C are sectional views thereof. .
　図６に示すように、調節用芯材１０ａは、合成樹脂など可撓性のある棒状の部材を本体として、その内部に設けられ、その調節用芯材１０ａの長手方向に沿って形成される１本の棒状の芯材を有している。本変更例２に係る芯材は、同６（ｂ）及び（ｃ）に示すように、径方向断面が扁平な扁平芯材１５となっている。この扁平芯材１５は、径断面の縦と横とでは、その厚みが異なることから、径方向に作用する撓み変形Ｐの中心軸Ｃに対する角度θ、言い換えれば、撓み変形Ｐによる曲げ応力の作用方向が、中心軸Ｃを含む所定断面Ｓに対する角度θに応じて、その撓みに対する耐力が変化するようになっている。 As shown in FIG. 6, the adjustment core member 10 a is provided inside a flexible rod-like member such as a synthetic resin as a main body, and is formed along the longitudinal direction of the adjustment core member 10 a. It has one rod-like core material. As shown in FIGS. 6 (b) and 6 (c), the core material according to the second modification example is a flat core material 15 having a flat radial cross section. Since the flat core material 15 has different thicknesses in length and width of the radial cross section, the angle θ with respect to the central axis C of the bending deformation P acting in the radial direction, in other words, the action of the bending stress due to the bending deformation P. In accordance with the angle θ with respect to the predetermined cross section S including the central axis C, the proof stress with respect to the direction changes.
　このような構成により、リアグリップ部２１を介して調節用芯材１０ａを回転させ、図６（ｂ）に示すように、扁平芯材１５の断面長手方向を撓み変形方向Ｌと平行にさせることで、調節用芯材１０ａの硬度を高くすることができるので、撓み変形方向Ｌの撓み量を小さくすることができる。一方、図６（ｃ）に示すように、リアグリップ部２１を９０度回転させ、上記θが９０°となるようにして、扁平芯材１５の断面長手方向を撓み変形方向Ｌと直交させることで、調節用芯材１０の硬度を低くすることができ、撓み変形方向Ｌへの撓み量を大きくすることができる。 With such a configuration, the adjusting core member 10a is rotated via the rear grip portion 21, and the longitudinal direction of the cross section of the flat core member 15 is made parallel to the bending deformation direction L as shown in FIG. Thus, since the hardness of the adjusting core member 10a can be increased, the amount of bending in the bending deformation direction L can be reduced. On the other hand, as shown in FIG. 6C, the rear grip portion 21 is rotated 90 degrees so that the θ is 90 °, and the longitudinal direction of the cross section of the flat core material 15 is orthogonal to the bending deformation direction L. Thus, the hardness of the adjusting core member 10 can be lowered, and the amount of bending in the bending deformation direction L can be increased.
（変更例３）
　次いで、変更例３について説明する。図７は、変更例３に係る調節用芯材の構成を示す説明図であり、同図（ａ）は、斜視図を示し、同図（ｂ）は、側面図を示し、同図（ｃ）及び（ｄ）は、その断面図である。 (Modification 3)
Next, Modification Example 3 will be described. FIGS. 7A and 7B are explanatory views showing the configuration of the adjustment core material according to the modified example 3. FIG. 7A shows a perspective view, FIG. 7B shows a side view, and FIG. ) And (d) are cross-sectional views thereof.
　図７（ａ）に示すように、調節用芯材１０ａは、可撓性のある棒状の部材であり、その上面に、その長手方向に沿って複数の切り込み１６が形成されている。各切り込み１６は、調節用芯材１０ａの長手方向と直交する幅方向（径方向）に形成されており、その深さは、撓ませたい大きさによって種々変更可能である。すなわち、撓みを小さくしたい場合は切り込みを浅くし、大きくしたい場合には切り込みを深くする。 As shown in FIG. 7 (a), the adjustment core member 10a is a flexible rod-like member, and a plurality of cuts 16 are formed on the upper surface thereof along the longitudinal direction thereof. Each notch 16 is formed in the width direction (radial direction) orthogonal to the longitudinal direction of the adjusting core member 10a, and the depth thereof can be variously changed depending on the size to be bent. That is, when it is desired to reduce the deflection, the cut is made shallower, and when it is desired to make it larger, the cut is made deeper.
　このような構成により、リアグリップ部２１を介して調節用芯材１０ａを回転させ、図７（ｃ）に示すように、切り込み１６の切込方向（切り込みの深さ方向）を撓み変形方向Ｌと平行に配置させることで、調節用芯材１０ａの耐力を低くすることができ、図７（ｂ）に示すように、撓み変形方向Ｌへの撓み量を大きくすることができる。一方、図７（ｄ）に示すように、リアグリップ部２１を９０～１８０°回転させ、切り込み１６の切込方向を撓み変形方向Ｌと直交或いは逆方向とさせることで、調節用芯材１０の硬度を高くすることができ、撓み変形方向Ｌへの撓み量を小さくすることができる。 With such a configuration, the adjustment core member 10a is rotated via the rear grip portion 21, and the cutting direction (the depth direction of the cutting) is changed as shown in FIG. By arranging them in parallel with each other, the proof stress of the adjusting core member 10a can be reduced, and the amount of bending in the bending deformation direction L can be increased as shown in FIG. On the other hand, as shown in FIG. 7 (d), the rear grip 21 is rotated by 90 to 180 °, and the cutting direction of the cut 16 is set to be perpendicular to or opposite to the bending deformation direction L. Can be increased, and the amount of bending in the bending deformation direction L can be reduced.
　これらの変更例のように、調節用芯材１０ａとして棒状の部材を用い、その内部に芯材を挿入したり、外部に切り込みを形成したりすることで、リアグリップ部２１の回転角度に応じて、段階的に調節用芯材１０の硬度を変化させることができるので、掛かった魚のサイズや種類、性質、水面・水中の状況などに応じて刻々と変化する竿に必要な剛性や撓み量に追従することができる。そのため、本変更例によれば、剛性及び撓み量の調節を瞬時に行える操作性を維持し、無段階且つ微妙な調節を可能とすることができる。 As in these modified examples, a rod-shaped member is used as the adjustment core material 10a, and the core material is inserted into the inside or a notch is formed outside, so that the rotation angle of the rear grip portion 21 can be adjusted. Because the hardness of the adjusting core 10 can be changed step by step, the rigidity and deflection required for the dredging that changes momentarily according to the size, type, nature, surface of the fish, and underwater conditions. Can follow. For this reason, according to this modified example, it is possible to maintain the operability of instantaneously adjusting the rigidity and the deflection amount, and to perform stepless and delicate adjustment.
　なお、上述した変更例１において、調節用芯材１０ａの内部に２つの芯材を配置させたが、本発明は、これに限定するものではなく、３以上の芯材を配置させてもよい。また、内部に配置させた芯材として断面円形の芯材を用いたが、本発明は、これに限定するものではなく、例えば、断面が略三角形状やハート形など種々の形状の芯材を用いることもできる。例えば、断面が略三角形状の芯材を用いた場合、調整用芯材を回転させると、撓み変形方向Ｌの軸上に位置する芯材の厚みが変化するので、その厚みによって撓み量を変化させることができる。 In addition, in the modification 1 mentioned above, although two core materials were arrange | positioned inside the adjustment core material 10a, this invention is not limited to this, You may arrange | position three or more core materials. . In addition, although a core material having a circular cross section was used as the core material arranged inside, the present invention is not limited to this, and for example, core materials having various shapes such as a substantially triangular shape or a heart shape are used. It can also be used. For example, when a core material having a substantially triangular cross section is used, when the adjustment core material is rotated, the thickness of the core material located on the axis in the bending deformation direction L changes. Can be made.
　さらには、上述した各変更例では、リアグリップ部２１で調節用芯材１０ａを、竿本体５の内部で回転させて、その硬度を調節するようにしたが、本発明はこれに限定されるものではなく、調節用芯材１０ａを竿本体５内部に固定し、釣竿１自体を回転させてその硬度を調節するようにしてもよい。詳述すると、上述した変更例１～３の調節用芯材１０ａを竿本体５の内部に固定し、釣竿１自体を回転させることで、調節用芯材１０ａの径方向に作用する撓み変形Ｐの中心軸Ｃに対する角度θ、言い換えれば、撓み変形Ｐによる曲げ応力の作用方向が、中心軸Ｃを含む所定断面Ｓに対する角度θに応じて、その撓みに対する耐力を変化させる。この場合には、竿本体５の構造を簡略化することができ、製造コストを低減できる。 Furthermore, in each of the above-described modifications, the adjustment core member 10a is rotated inside the bag main body 5 by the rear grip portion 21 to adjust the hardness thereof, but the present invention is limited to this. Instead of this, the adjusting core member 10a may be fixed inside the rod body 5 and the fishing rod 1 itself may be rotated to adjust its hardness. More specifically, the deformation core P that acts in the radial direction of the adjustment core member 10a by rotating the fishing rod 1 itself by fixing the adjustment core member 10a of the first to third modification examples described above to the inside of the rod body 5. The angle θ with respect to the central axis C, in other words, the acting direction of the bending stress due to the bending deformation P changes the yield strength against the bending according to the angle θ with respect to the predetermined section S including the central axis C. In this case, the structure of the bag main body 5 can be simplified, and the manufacturing cost can be reduced.
