Description

本発明は、釣竿に関し、特に、釣糸を先端に結着する釣糸結着部の基端を支える筒状軸杆を穂先部に保持させた釣竿に関する。 The present invention relates to a fishing rod, and more particularly, to a fishing rod in which a tubular shaft rod that supports a proximal end of a fishing line binding portion that binds a fishing line to a distal end is held at a tip portion.

例えば鮎竿あるいは渓流竿等のように、穂先部に釣糸の道糸を結着する釣竿には、釣糸を結着する釣糸結着部を、筒状軸杆を介して穂先部に接着固定し、この筒状軸杆の軸線を中心として回転自在に支え、この釣糸結着部を軸方向に移動自在の筒状保持体で釣糸結着部から釣糸が脱落するのを防止したものが知られている（例えば特開２０００−１５７１０８参照）。
特開２０００−１５７１０８ For example, a fishing rod that binds a fishing line to the tip of a fishing rod, such as a kite or a mountain stream kite, is bonded and fixed to the tip of the fishing rod via a cylindrical shaft rod. It is known that the fishing line binding portion is supported by the cylindrical shaft rod so as to be rotatable, and the fishing line binding portion is movable in the axial direction to prevent the fishing line from dropping off from the fishing line binding portion. (See, for example, JP-A-2000-157108).
JP 2000-157108 A

しかし、このような従来の釣竿では、釣糸結着部を支える筒状保持体が、繊維強化樹脂プリプレグ等により中空あるいは中実に形成された穂先竿の外周に、接着剤を介して固定される。穂先竿は極めて細径の構造を有し、この細径の穂先竿の外周に嵌合する筒状軸杆も細径構造に形成されるため、接着状態にバラツキが生じ易く、一方、このような接着状態は、外部からは確認することができない。したがって、穂先部に対する釣糸結着部の固定強度にもバラツキが生じる。 However, in such a conventional fishing rod, the cylindrical holder that supports the fishing line binding portion is fixed to the outer periphery of the tip rod hollow or solidly formed by a fiber reinforced resin prepreg or the like via an adhesive. Since the tip collar has a very small diameter structure, and the cylindrical shaft collar fitted to the outer periphery of the small diameter tip collar is also formed in a small diameter structure, the adhesive state is likely to vary, whereas Such an adhesive state cannot be confirmed from the outside. Therefore, the fixing strength of the fishing line binding portion with respect to the tip portion also varies.

本発明は、このような事情に基いてなされたもので、穂先部に装着された釣糸結着部の抜けや脱落を防止した釣竿を提供することを目的とする。 The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing rod that prevents the fishing line binding portion attached to the tip portion from coming off or falling off.

上記目的を達成するため、本発明によると、釣糸を結着する釣糸結着部を支える筒状軸杆を備え、この筒状軸杆を金属製の穂先部に、軸方向の相対移動を規制する保持手段で保持させた釣竿が提供される。
前記筒状軸杆の軸方向に沿って、前記釣糸結着部が外部に露出する位置とこの釣糸結着部の全体を内部に収納する位置との間を移動可能な筒状保持体を更に備えてもよい。 In order to achieve the above object, according to the present invention, a cylindrical shaft rod that supports a fishing line binding portion that binds a fishing line is provided, and the cylindrical shaft rod is used as a metal tip to restrict relative movement in the axial direction. A fishing rod held by holding means is provided.
A cylindrical holder further movable along the axial direction of the cylindrical shaft rod between a position where the fishing line binding portion is exposed to the outside and a position where the entire fishing line binding portion is housed inside. You may prepare.

前記保持手段は、前記金属製の穂先部の外周に周方向に沿って延設された凹部と、前記筒状軸杆の内周から突出させた周方向に延びる凸部とを有し、この凸部を、前記凹部に圧入することにより、金属製の穂先部に筒状軸杆を圧着固定することができる。 The holding means has a concave portion extending along the circumferential direction on the outer periphery of the metal tip, and a convex portion extending in the circumferential direction protruding from the inner circumference of the cylindrical shaft rod. By press-fitting the convex part into the concave part, the cylindrical shaft can be fixed to the metal tip part by pressure bonding.

これとは逆に、前記保持手段は、前記金属製の穂先部の外周に周方向に沿って設けられた凸部と、前記筒状軸杆の内周に凹部又はこの筒状軸杆を半径方向に貫通する貫通孔を設け、前記凸部を、前記凹部又は貫通孔に嵌合させることにより、金属製の穂先部に筒状軸杆を固定してもよい。 On the contrary, the holding means has a convex portion provided along the circumferential direction on the outer periphery of the metal tip portion, and a concave portion or the cylindrical shaft rod on the inner periphery of the cylindrical shaft rod. A cylindrical shaft rod may be fixed to the metal tip by providing a through hole penetrating in the direction and fitting the convex portion into the concave portion or the through hole.

このような保持手段は、凹部が０．１ｍｍ以上の深さを有することが好ましい。
また、保持手段は、金属製の穂先部と筒状軸杆との互いに嵌合する部位で、軸方向に沿って複数箇所に設けてもよい。
また、保持手段は、金属製の穂先部と筒状軸杆とのそれぞれに設けられ、互いに螺合によって固定されるねじ部を有することもできる。 In such a holding means, it is preferable that the recess has a depth of 0.1 mm or more.
In addition, the holding means may be provided at a plurality of locations along the axial direction in a portion where the metal tip portion and the cylindrical shaft rod are fitted to each other.
In addition, the holding means may have a threaded portion that is provided on each of the metal tip portion and the cylindrical shaft rod, and is fixed to each other by screwing.

本発明の釣竿によると、金属製の穂先部に、例えば凹部と凸部との圧着による保持手段で、筒状軸杆が保持されることにより、釣糸結着部を支える筒状軸杆の固定強度を高めることができ、筒状軸杆および釣糸結着部が穂先部から抜け落ち難い。
釣糸結着部が外部に露出する位置とこの釣糸結着部の全体を内部に収納する位置との間を移動可能な筒状保持体を更に備える場合には、釣糸結着部を保護し、釣糸が意に反して外れるのを防止することができる。 According to the fishing rod of the present invention, the cylindrical shaft rod that supports the fishing line binding portion is secured to the metal tip by holding the cylindrical shaft rod with a holding means by, for example, pressing the concave portion and the convex portion. The strength can be increased, and the cylindrical shaft rod and the fishing line binding portion are difficult to come off from the tip portion.
In the case of further comprising a cylindrical holder that can move between a position where the fishing line binding portion is exposed to the outside and a position where the entire fishing line binding portion is housed inside, the fishing line binding portion is protected, It is possible to prevent the fishing line from coming off unexpectedly.

このような保持手段の凹部が０．１ｍｍ以上の深さを有する場合には、金属製の穂先部に対して確実かつ容易に固定することができる。
保持手段が、ねじ部で形成される場合には、より強固な固定強度が得られると共に、固定する部位における固定曲がりが発生し難く、取付けおよび取外しが容易である。 When the concave portion of the holding means has a depth of 0.1 mm or more, it can be reliably and easily fixed to the metal tip portion.
When the holding means is formed of a threaded portion, it is possible to obtain a stronger fixing strength, and it is difficult to cause a fixing bending at a fixing portion, and it is easy to attach and remove.

図１および図２は、本発明の好ましい実施形態による釣竿１０の穂先部を示す。
本実施形態の釣竿１０は、例えば鮎竿あるいは渓流竿として大きく撓むことができると共に魚信に敏感な金属製の穂先竿１２を備え、この穂先竿１２の先端部すなわち穂先部１２ａに、釣糸を結着するためのフック状の釣糸結着部１４を有する結着装置Ｋを取付けてある。 1 and 2 show the tip of a fishing rod 10 according to a preferred embodiment of the present invention.
The fishing rod 10 of the present embodiment is provided with a metal tip rod 12 that can be greatly bent as a rod or a mountain stream rod and is sensitive to fish faith. A binding device K having a hook-like fishing line binding portion 14 for binding the seam is attached.

この穂先竿１２は、例えばＮｉ−Ｔｉ系合金、Ｎｉ−Ｔｉ−Ｆｅ系合金、Ｎｉ−Ｔｉ−Ｃｕ系合金、Ｎｉ−Ｔｉ−Ｃｒ系合金等、伸び率が３％以上（具体的には５〜８％程度）で、例えば軸方向の引張り荷重で約３％以上の伸びを生じさせる状態に形状変化をさせた際に、約７０％以上の復元率で元の形状に回復することができる超弾性合金で形成してある。この穂先竿１２は、その全体をこのような超弾性合金により、中実構造あるいは中空構造に形成することができる。このような穂先竿１２の先端部は、先側と元側とが同径のストレート形状が好ましいが、外周面を緩いテーパ状に形成した先細り形状であってもよい。 For example, the nib 12 is Ni-Ti-based alloy, Ni-Ti-Fe-based alloy, Ni-Ti-Cu-based alloy, Ni-Ti-Cr-based alloy or the like, and has an elongation of 3% or more (specifically, 5 For example, when the shape is changed to a state in which an elongation of about 3% or more is caused by an axial tensile load, the original shape can be recovered with a restoration rate of about 70% or more. It is made of a superelastic alloy. The entire tip 12 can be formed into a solid structure or a hollow structure by such a superelastic alloy. The tip portion of the tip ridge 12 is preferably a straight shape having the same diameter on the front side and the original side, but may have a tapered shape with a loosely tapered outer peripheral surface.

なお、穂先竿１２は、全体を超弾性合金で形成することに代え、図示しない芯材にこのような超弾性合金を用い、その外側に繊維強化樹脂層を形成してもよい。この繊維強化樹脂層を外側に設ける場合は、超弾性合金の弾性率が約６４Ｎ／ｍｍ^２のときに、約４．９〜２９４Ｎ／ｍｍ^２の範囲の弾性率を持つ炭素繊維強化樹脂あるいはガラス繊維強化樹脂を用いることが好ましい。このような繊維強化樹脂層を外側に形成する場合であっても、上述の結着装置Ｋを取付ける穂先部１２ａには、このような樹脂層で覆われることなく、外周部には金属を露出させることが好ましい。 In addition, instead of forming the entire tip 12 with a superelastic alloy, such a superelastic alloy may be used for a core material (not shown) and a fiber reinforced resin layer may be formed on the outside thereof. When providing the fiber reinforced resin layer on the outside, when the elastic modulus of the superelastic alloy is approximately 64N / mm ^2, the carbon fiber reinforced resin or glass having an elastic modulus in the range of about 4.9~294N / mm ² It is preferable to use a fiber reinforced resin. Even in the case where such a fiber reinforced resin layer is formed on the outside, the tip portion 12a to which the above-described binding device K is attached is not covered with such a resin layer, and the metal is exposed to the outer peripheral portion. It is preferable to make it.

本実施形態の釣竿１０は、このような金属製の穂先竿１２の先端部である穂先部１２ａに、この外周に周方向に沿って断面が略矩形状の凹部１６を延設してあり、この凹部１６を介して釣糸用の結着装置Ｋを取付けることができる。 In the fishing rod 10 of the present embodiment, a concave portion 16 having a substantially rectangular cross section is provided along the circumferential direction on the outer periphery of the tip portion 12a which is the tip portion of such a metal tip rod 12. A fishing line binding device K can be attached through the recess 16.

この結着装置Ｋは、釣糸結着部１４を支える筒状軸杆１８を備え、この筒状軸杆１８が穂先部１２ａの外周部に嵌合される。本実施形態の筒状軸杆１８は、基端側が開口しかつ先端側が閉じ、穂先部１２ａの外面との間に略０．１ｍｍ程度の僅かな間隙を形成する内孔２０を有する。この筒状軸杆１８の内孔２０内に、先端が内孔２０の閉端部に当接するまで穂先竿１２の穂先部１２ａを挿入し、穂先部１２ａに形成した凹部１６に対応した部位を筒状軸杆１８の外側からカシメ等により、この凹部１６内に筒状軸杆１８の一部が形成する凸部２２を圧入させることで、穂先部１２ａに対する筒状軸杆１８の軸方向の相対移動を規制することができる。したがって、本実施形態では、穂先部１２ａの外周に形成した凹部１６と筒状軸杆１８の内周から突出して凹部１６内に圧入される凸部２２とが、穂先竿１２の穂先部１２ａと結着装置Ｋの筒状軸杆１８との軸方向の相対移動を規制する保持手段を形成する。 The binding device K includes a cylindrical shaft rod 18 that supports the fishing line binding portion 14, and the cylindrical shaft rod 18 is fitted to the outer peripheral portion of the tip portion 12a. The cylindrical shaft rod 18 of the present embodiment has an inner hole 20 that is open at the proximal end and closed at the distal end, and forms a slight gap of about 0.1 mm with the outer surface of the tip portion 12a. The tip 12a of the tip 12 is inserted into the inner hole 20 of the cylindrical shaft 18 until the tip comes into contact with the closed end of the inner hole 20, and a portion corresponding to the recess 16 formed in the tip 12a is formed. By pressing the convex portion 22 formed by a part of the cylindrical shaft rod 18 into the concave portion 16 by caulking or the like from the outside of the cylindrical shaft rod 18, the axial direction of the cylindrical shaft rod 18 with respect to the tip 12 a Relative movement can be restricted. Therefore, in this embodiment, the concave portion 16 formed on the outer periphery of the tip portion 12a and the convex portion 22 that protrudes from the inner periphery of the cylindrical shaft rod 18 and is press-fitted into the concave portion 16 are the tip portion 12a of the tip portion 12a. A holding means for restricting relative movement in the axial direction of the binding device K with the cylindrical shaft rod 18 is formed.

この筒状軸杆１８の先端側には、周方向溝２４を形成した首部２６を穂先部１２ａと同軸状に形成してある。一方、釣糸結着部１４の元側には頭部２８が一体に設けられ、この頭部２８の元側から延びるスカート部３０がこの首部２６の外周上に装着される。このスカート部３０の外径は、頭部２８よりも僅かに縮径されており、頭部２８との間に段部２９が形成される。また、スカート部３０の内周からは、カシメ等によりスカート部３０の一部で形成した突出部３２が周方向溝２４内に突入して、この周方向溝２４と緩く嵌合する。これにより、釣糸結着部１４が穂先部１２ａ上に、軸方向移動不能でかつ穂先部１２ａの軸線を中心として回転自在に装着され、結着した釣糸が捩れるのを防止する。本実施形態では、筒状軸杆１８の首部２６は、内孔２０を形成した部位の外径よりも、スカート部３０の肉厚分だけ小径に形成してあり、スカート部３０の端部が筒状軸杆１８の外周面上に段部を形成することはない。換言すると、スカート部３０の外径は、筒状軸杆１８の内孔２０を形成した部位の外径とほぼ等しい。 A neck portion 26 having a circumferential groove 24 formed coaxially with the tip portion 12a is formed on the distal end side of the cylindrical shaft rod 18. On the other hand, a head portion 28 is integrally provided on the former side of the fishing line binding portion 14, and a skirt portion 30 extending from the former side of the head portion 28 is mounted on the outer periphery of the neck portion 26. The outer diameter of the skirt portion 30 is slightly smaller than that of the head portion 28, and a step portion 29 is formed between the head portion 28. Further, from the inner periphery of the skirt portion 30, a protruding portion 32 formed by a part of the skirt portion 30 by caulking or the like enters the circumferential groove 24 and loosely engages with the circumferential groove 24. As a result, the fishing line binding portion 14 is mounted on the tip portion 12a so as not to move in the axial direction and is rotatable about the axis of the tip portion 12a, thereby preventing the bound fishing line from being twisted. In the present embodiment, the neck portion 26 of the cylindrical shaft rod 18 is formed to have a smaller diameter than the outer diameter of the portion where the inner hole 20 is formed, by the thickness of the skirt portion 30, and the end portion of the skirt portion 30 is No step portion is formed on the outer peripheral surface of the cylindrical shaft rod 18. In other words, the outer diameter of the skirt portion 30 is substantially equal to the outer diameter of the portion where the inner hole 20 of the cylindrical shaft rod 18 is formed.

また、筒状軸杆１８の元側部には、少なくとも周方向の一部を外方に突出させた膨出部３４を形成してある。この膨出部３４の先側は、穂先部１２ａの軸線に対して僅かな角度で先細状に傾斜する傾斜部３６を有する。この傾斜部３６は、後述する筒状保持体３８の後縁部を係止することができ、穂先部１２ａを下向きにして配置したときに、この筒状保持体３８が自重で先端側に滑落するのを阻止する。 Further, a bulging portion 34 is formed on the base side portion of the cylindrical shaft 18 so that at least a portion in the circumferential direction protrudes outward. The tip side of the bulging portion 34 has an inclined portion 36 that is inclined in a tapered manner at a slight angle with respect to the axis of the tip portion 12a. The inclined portion 36 can lock a rear edge portion of a cylindrical holding body 38 to be described later, and when the tip portion 12a is arranged downward, the cylindrical holding body 38 slides down to the front end side by its own weight. To stop doing.

筒状保持体３８は、筒状軸杆１８の外側に装着され、先側の端部を外方に折り返して滑らかな湾曲面に形成した円筒状形状を有し、図１の（Ａ）に示す引込位置と、図１の（Ｂ）に示す突出位置との間を軸方向に移動することができる。この筒状保持体３８の内径は、釣糸結着部１４を突出させた頭部２８よりも、先側が僅かに大きく、元側が僅かに小さく形成してあり、引込位置に配置されて元側を膨出部３４の傾斜部３６で係止されたときに、釣糸結着部１４を露出して釣糸結着操作を容易とし、突出位置に配置されたときに、釣糸結着部１４を完全に覆い、フック状形状の釣糸結着部１４から釣糸が脱落するのを防止する。突出位置に配置されたときに、筒状保持体３８の先側端部が滑らかな湾曲面で形成されているため、釣糸を傷つけることはない。 The cylindrical holder 38 is attached to the outside of the cylindrical shaft 18 and has a cylindrical shape formed with a smooth curved surface by folding the end portion of the front side outward, as shown in FIG. It is possible to move in the axial direction between the retracted position shown and the protruding position shown in FIG. The inner diameter of the cylindrical holder 38 is slightly larger on the front side and slightly smaller on the original side than the head portion 28 from which the fishing line binding portion 14 is projected, and is arranged at the retracted position so that the original side is arranged. When locked by the inclined portion 36 of the bulging portion 34, the fishing line binding portion 14 is exposed to facilitate the fishing line binding operation, and when it is disposed at the protruding position, the fishing line binding portion 14 is completely removed. Covering and preventing the fishing line from dropping off from the hook-shaped fishing line binding portion 14. When arranged at the protruding position, the front end of the cylindrical holder 38 is formed with a smooth curved surface, so that the fishing line is not damaged.

更に、この筒状保持体３８は、突出位置に配置されたときに、頭部２８の先側に係合する小突部４０を内周側に突出させてある。これにより、魚釣中に、釣糸結着部１４に一端を結ばれた釣糸に作用する力で、筒状保持体３８が意に反して引込位置に戻るのを防止する。また、図示の筒状保持体３８は、引込位置にあるときに筒状軸杆１８の首部２６に形成した周方向溝２４および突出部３２を露出させ、突出位置にあるときに穂先部１２ａの凹部１６および突部２２を露出させる長さに形成してあるが、一方の位置にあるときに、周方向溝２４および凹部１６の双方がこの筒状保持体３８の外側に配置される長さに形成してもよい。 Further, when the cylindrical holder 38 is arranged at the protruding position, a small protrusion 40 that is engaged with the front side of the head 28 is protruded to the inner peripheral side. This prevents the cylindrical holder 38 from returning to the retracted position unexpectedly by the force acting on the fishing line having one end tied to the fishing line binding portion 14 during fishing. The illustrated cylindrical holding body 38 exposes the circumferential groove 24 and the protruding portion 32 formed in the neck portion 26 of the cylindrical shaft 18 when in the retracted position, and the tip portion 12a of the tip portion 12a when in the protruding position. The length is such that the recess 16 and the protrusion 22 are exposed, but the length in which both the circumferential groove 24 and the recess 16 are disposed outside the cylindrical holder 38 when the recess 16 and the protrusion 22 are in one position. You may form in.

このような結着装置Ｋを形成する筒状軸杆１８および筒状保持体３８は、例えばＳＵＳ、真鍮、アルミニウム合金あるいはチタン等の金属の他、繊維強化樹脂やセラミックス等の適宜の材料で形成することができる。特に、筒状軸杆１８を金属で形成する場合には、金属製の穂先部１２ａとの固定強度を高めることができ、この筒状軸杆１８および釣糸結着部１４が穂先部１２ａから抜け落ちるのを防止することができる。また、釣糸結着部１４、頭部２８およびスカート部３０は十分な強度を持つ金属で形成することが好ましい。 The cylindrical shaft 18 and the cylindrical holder 38 that form such a binding device K are made of an appropriate material such as fiber reinforced resin or ceramics in addition to a metal such as SUS, brass, aluminum alloy, or titanium. can do. In particular, when the cylindrical shaft rod 18 is formed of metal, the fixing strength with the metal tip portion 12a can be increased, and the cylindrical shaft rod 18 and the fishing line binding portion 14 fall off from the tip portion 12a. Can be prevented. Moreover, it is preferable to form the fishing line binding part 14, the head part 28, and the skirt part 30 with a metal having sufficient strength.

このような結着装置Ｋを穂先部１２ａに取付ける場合は、釣糸結着部１４と筒状軸杆１８と筒状保持体３０とから釣糸の結着装置Ｋを組立てた後、以下のように行うことが好ましい。
まず、金属製の穂先部１２ａの外面に接着剤を塗布し、筒状軸杆１８の内孔２０内に挿入する。このとき、筒状軸杆１８の内孔２０の内面にも接着剤を塗布してもよい。
筒状軸杆１８の開口端から漏出した余分の接着剤を払拭した後、筒状軸杆１８の穂先部１２ａの凹部１６に対応した部位を、カシメ等により圧着し、凸部２２を凹部１６内に圧入する。この凸部２２は、筒状軸杆１８の全周にわたって連続的に形成してもよく、あるいは、不連続状態に少なくとも一箇所に形成してもよい。穂先部１２ａの外径と筒状軸杆１８の内孔２０の内径との差は、０．１ｍｍ程度であるため、簡単かつ確実に圧着することができ、ガタツキを生じさせることもない。 When attaching such a binding device K to the tip portion 12a, after assembling the fishing line binding device K from the fishing line binding portion 14, the cylindrical shaft 18 and the cylindrical holder 30, as follows: Preferably it is done.
First, an adhesive is applied to the outer surface of the metal tip 12 a and inserted into the inner hole 20 of the cylindrical shaft 18. At this time, an adhesive may also be applied to the inner surface of the inner hole 20 of the cylindrical shaft rod 18.
After the excess adhesive leaked from the opening end of the cylindrical shaft rod 18 is wiped off, the portion corresponding to the concave portion 16 of the tip portion 12a of the cylindrical shaft rod 18 is crimped by caulking or the like, and the convex portion 22 is compressed into the concave portion 16. Press fit inside. The convex portion 22 may be formed continuously over the entire circumference of the cylindrical shaft 18 or may be formed in at least one location in a discontinuous state. Since the difference between the outer diameter of the tip portion 12a and the inner diameter of the inner hole 20 of the cylindrical shaft rod 18 is about 0.1 mm, it can be easily and reliably crimped and does not cause backlash.

図２に示すように、この穂先部１２ａと筒状軸杆１８とが金属で形成されている場合には、凹部１６の深さｄがほぼ０．１ｍｍ以上に形成されていることが好ましい。このような凹部１６に圧入される凸部２２は、凹部１６の側壁部１６ａに係合する側部を内孔２０の周面から略直角に立上げることも可能である。しかし、凹部１６の側壁部１６ａに係合するものであれば、凸部２２の側部を傾斜面で形成しあるいは湾曲面で形成してもよい。いずれの場合も、その形状的な係合により、これらの２つの部材を確実に抜け止め係合させることができる。また、圧着は、凹部１６と凸部２２との噛合いを生じさせる場合に限らず、穂先部１２ａの円筒状外面とこれに対向する筒状軸部１８の円筒状内面とを、互いに圧接する状態として、その押圧力で、これらの２つの部材を抜け止め係合させてもよい。但し、この場合の固定力は、凹部１６と凸部２２とを嵌合させた場合よりも低下するため、それぞれの係合面を粗面状に形成しておくことが好ましい。 As shown in FIG. 2, when the tip 12a and the cylindrical shaft 18 are made of metal, it is preferable that the depth d of the recess 16 is formed to be approximately 0.1 mm or more. The convex portion 22 press-fitted into the concave portion 16 can also be configured to raise a side portion that engages with the side wall portion 16 a of the concave portion 16 from the peripheral surface of the inner hole 20 at a substantially right angle. However, as long as it engages with the side wall part 16a of the concave part 16, the side part of the convex part 22 may be formed with an inclined surface or a curved surface. In any case, these two members can be securely engaged with each other by the shape engagement. The crimping is not limited to the case where the concave portion 16 and the convex portion 22 are engaged with each other, and the cylindrical outer surface of the tip portion 12a and the cylindrical inner surface of the cylindrical shaft portion 18 opposed thereto are pressed against each other. As a state, these two members may be engaged with each other with the pressing force. However, since the fixing force in this case is lower than that in the case where the concave portion 16 and the convex portion 22 are fitted, it is preferable to form each engaging surface in a rough surface shape.

このように圧着した後、接着剤が硬化するまで、筒状軸杆１８側すなわち穂先部１２ａを上側にした状態に保持し、筒状軸杆１８を所要位置に保持しておくことが好ましい。 After crimping in this manner, it is preferable to hold the cylindrical shaft 18 in a required position while holding the cylindrical shaft 18 side, that is, the tip portion 12a up until the adhesive is cured.

なお、筒状軸杆１８と穂先部１２ａとの圧着は、接着剤が硬化した後に行っても良い。特に、エポキシ樹脂系の接着剤を使用した場合には、この接着剤が硬化した後も弾性を有しているため、圧着により接着層を破壊する虞はないからである。なお、接着剤は、このようなエポキシ樹脂系の他にも、シアノアクリレート系、塩化ビニール系、嫌気性アクリル系であってもよい。また、上述とは逆に、接着剤を塗布することなく、筒状軸杆１８と穂先部１２ａと圧着し、この後、例えばシアノアクリレート系接着剤等の瞬間接着剤をその隙間から流し込んでもよい。 In addition, you may perform the crimping | compression-bonding with the cylindrical shaft rod 18 and the tip part 12a after an adhesive agent hardens | cures. In particular, when an epoxy resin-based adhesive is used, the adhesive layer remains elastic even after it is cured, so that there is no possibility of destroying the adhesive layer by pressure bonding. In addition to the epoxy resin type, the adhesive may be a cyanoacrylate type, a vinyl chloride type, or an anaerobic acrylic type. Also, contrary to the above, the cylindrical shaft 18 and the tip 12a may be pressure-bonded without applying an adhesive, and thereafter, an instantaneous adhesive such as a cyanoacrylate adhesive may be poured from the gap. .

このように釣糸結着装置Ｋを穂先部１２ａに取付けられた釣竿１０は、金属製の穂先部１２ａと筒状軸杆１８とを、互いに形状的に噛合いあるいは押圧する強固な保持手段で連結したことにより、固定強度を高めることができ、筒状軸杆１８が穂先部１２ａから抜け落ちるのを防止することができる。 In this way, the fishing rod 10 with the fishing line binding device K attached to the tip portion 12a is connected to the metallic tip portion 12a and the cylindrical shaft rod 18 by a strong holding means that meshes or presses each other in shape. As a result, the fixing strength can be increased, and the cylindrical shaft 18 can be prevented from falling off the tip portion 12a.

図３は、種々の変形例による釣竿１０を示す。なお、図３に示す変形例も基本的には上述の実施形態と同様であるため、同様な部位には同様な符号を付し、その詳細な説明を省略する。 FIG. 3 shows a fishing rod 10 according to various modifications. Note that the modification shown in FIG. 3 is also basically the same as that of the above-described embodiment, and thus similar parts are denoted by the same reference numerals and detailed description thereof is omitted.

図３の(Ａ）は、上述の実施形態における保持手段の凹部１６に代えて、穂先部１２ａの外周に周方向に沿って凸部４２を連続的に設け、内孔２０の内面にこの凸部４２が嵌合する周方向凹部４４を周方向に沿って設けたものである。また、図３の（Ｂ）は、穂先部１２ａの外周に、周方向に沿って一定の間隔をおいて複数の凸部４６を設け、筒状軸杆１８の壁面を半径方向に貫通する貫通孔４８を凸部４６に対応させて設けたものである。いずれの保持手段も、その形状的な噛合いにより、釣糸結着部１４を支える筒状軸杆３８の固定強度を高めることができ、筒状軸杆３８が穂先部１２ａから抜け落ち難い構造を形成する。 3A, instead of the concave portion 16 of the holding means in the above-described embodiment, a convex portion 42 is continuously provided along the circumferential direction on the outer periphery of the tip portion 12a, and this convex portion is formed on the inner surface of the inner hole 20. A circumferential recess 44 into which the portion 42 is fitted is provided along the circumferential direction. 3B, a plurality of convex portions 46 are provided on the outer periphery of the tip 12a at regular intervals along the circumferential direction, and penetrate through the wall surface of the cylindrical shaft 18 in the radial direction. The holes 48 are provided so as to correspond to the convex portions 46. Any holding means can increase the fixing strength of the cylindrical shaft rod 38 that supports the fishing line binding portion 14 by its shape meshing, and the cylindrical shaft rod 38 forms a structure that is difficult to come off from the tip portion 12a. To do.

また、図３の（Ｃ）は、穂先部１２ａの先端と筒状軸杆３８の内孔２０とに互いに螺合するねじを形成したねじ結合部５０により、これらの穂先部１２ａと筒状軸杆３８とを固定したものである。この場合には、結着装置Ｋの着脱が可能であり、必要に応じて結着装置Ｋのみを交換することができる。 3 (C) shows the tip portion 12a and the cylindrical shaft by a screw coupling portion 50 in which a screw that is screwed to the tip of the tip portion 12a and the inner hole 20 of the cylindrical shaft rod 38 is formed. This is a fixed base. In this case, the binding device K can be attached and detached, and only the binding device K can be replaced as necessary.

更に、図３の（Ｄ）は、図１に示す実施形態と同様な凹部１６が軸方向に間隔をおいて、例えば２箇所等の複数位置に配置し、これに対応する凸部２２を内孔２０の内面に形成したものである。この場合には、複数部位で穂先部１２ａと結着装置Ｋの筒状軸杆３８とを固定することができるため、より強固な固定強度が得られると共に、固定曲がり、すなわちカシメ等の圧着力が周方向に沿って不均等に作用することにより、筒状軸杆３８が穂先部１２ａの軸線に対して曲がる状態となることが防止される。 Further, FIG. 3D shows a concave portion 16 similar to that of the embodiment shown in FIG. 1 arranged at a plurality of positions such as two places at intervals in the axial direction, and the convex portions 22 corresponding to the concave portions 16 are arranged inside. It is formed on the inner surface of the hole 20. In this case, since the tip part 12a and the cylindrical shaft rod 38 of the binding device K can be fixed at a plurality of sites, a stronger fixing strength can be obtained and a fixed bending, that is, a crimping force such as caulking By acting unevenly along the circumferential direction, the cylindrical shaft rod 38 is prevented from being bent with respect to the axis of the tip portion 12a.

なお、図３の（Ｄ）の変形例のように、穂先部１２ａの軸方向に沿う複数部位で筒状軸杆１８を固定する場合には、その一方に、例えば図３の(Ａ）に示す凸部４２あるいは図３の（Ｂ）に示す凸部４６を用いることも可能である。
また、上述の実施形態あるいは変形例では、釣糸結着部１４の先側をフック状に形成し、このフック状に形成した部分に釣糸を掛けるようにしたが、これに限らず、螺旋状構造あるいはチチ輪状構造等の種々の構造に形成することができる。フック状構造に代えて、例えばリング状等の釣糸が抜け出る可能性の低い構造を採用する場合には、筒状保持体３２を省略することも可能である。この場合には、竿先部の軽量化が促進される。 3D, when the cylindrical shaft 18 is fixed at a plurality of portions along the axial direction of the tip 12a, for example, in FIG. 3A, It is also possible to use the convex portion 42 shown or the convex portion 46 shown in FIG.
Further, in the above-described embodiment or modification, the front side of the fishing line binding portion 14 is formed in a hook shape, and the fishing line is hung on the hook-shaped portion. Or it can form in various structures, such as a Chichi ring structure. In place of the hook-shaped structure, for example, when a structure such as a ring-shaped fishing line with a low possibility of coming out is employed, the cylindrical holding body 32 can be omitted. In this case, weight reduction of the tip part is promoted.
