Description

本発明は、釣り糸ガイドに関し、特に、フレームに釣糸案内部と固定部とを形成し、この固定部を筒状体の受け部に装着した釣り糸ガイドに関する。 The present invention relates to a fishing line guide, and more particularly to a fishing line guide in which a fishing line guide portion and a fixing portion are formed on a frame , and the fixing portion is attached to a receiving portion of a tubular body.

一般に、釣り糸ガイドは、釣り糸が釣り竿の表面に付着するのを防止するために、間隔をおいて釣り竿の外側に取付けられる。このような釣り糸ガイドには、糸通し環を支える金属製フレームをプラスチック製の竿保護管に固定したものが開発されている（例えば特許文献１参照）。 In general, the fishing line guide is attached to the outside of the fishing rod at an interval in order to prevent the fishing line from adhering to the surface of the fishing rod. Such fishing line guides have been developed in which a metal frame that supports a threading ring is fixed to a plastic rod protection tube (see, for example, Patent Document 1).

このプラスチック製の竿保護管は、フレームを装着する部位の後端側すなわち釣り竿の元側に、フレームの回り止め突起を形成すると共に、この後方で弾性変形する円筒部を後方に向けて径を小さくしたテーパ状に形成してある。また、フレームは、プレス加工により板状に形成し、竿保護管に固定する部分は、絞り加工により、水平部を有する管形に形成し、この管形の部分に回り止め用の切欠き部を形成してある。 This plastic rod protection tube is formed with a detent projection of the frame on the rear end side of the part where the frame is to be attached, that is, on the base side of the fishing rod. It is formed in a reduced taper shape. In addition, the frame is formed into a plate shape by pressing, and the portion that is fixed to the saddle protection tube is formed into a tubular shape having a horizontal portion by drawing, and a notch portion for preventing rotation is added to this tubular portion. Is formed.

このフレームを竿保護管に装着する際は、竿保護管の小径に形成した後方から管形の部分を挿入し、円筒部を弾性変形により縮径させつつ前方に向けて圧入し、回り止め突起に管形部分の切欠き部を嵌合することで、回り止め突起を損傷することなく、竿保護管上の所定位置にフレームを確実に固定するものである。
特開２００７−２８９０８７ When attaching this frame to the saddle protection tube, insert a tubular part from the back formed in the small diameter of the saddle protection tube, press-fit it forward while reducing the diameter of the cylindrical part by elastic deformation, By fitting the notch portion of the tube-shaped portion into the frame, the frame is securely fixed at a predetermined position on the saddle protection tube without damaging the anti-rotation projection.
JP2007-289087

しかし、従来の釣り糸ガイドは、釣り竿に取付けたときに、釣り糸ガイドの竿保護管が、フレームを挿入する側すなわちテーパ状形状の小径部を元側に配置することになり、釣り竿の外周面上で竿保護管が段差を形成し、更に、竿保護管とフレームとの径差により段差が形成される。これらの段差は、フレームよりも元側すなわち魚釣用リールに近接する側に位置するため、釣り糸が引っ掛かり易く、糸ガラミし易い。
本発明は、このような事情に基づいてなされたもので、釣り糸が絡まり難い釣り糸ガイドを提供することを目的とする。 However, when a conventional fishing line guide is attached to a fishing rod, the fishing rod guide's rod protection tube has a side where the frame is inserted, i.e., a tapered small diameter portion disposed on the original side. The heel protection tube forms a step, and further, a step is formed due to the difference in diameter between the heel protection tube and the frame. Since these steps are located on the original side of the frame, that is, on the side closer to the fishing reel, the fishing line is easily caught and the yarn is easily broken .
The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing line guide in which fishing lines are not easily entangled.

上記目的を達成するために、本発明に従う実施形態は、フレームに釣り糸案内部と固定部とを形成し、前記固定部を筒状体の受け部に装着し、釣り竿の前方の穂先側から後方の元側に沿って竿杆上を前後動し、前記竿杆の外周上に保持される釣り糸ガイドであって、前記筒状体は、受け部よりも軸方向後方で、前記筒状体の軸方向に沿う内孔の後端周縁部から前方の前端面に向けて拡径する滑らかな湾曲面状の外周面を有し、前記受け部との間に前端面を形成する大径部と、前記受け部よりも軸方向前方で、前記大径部の前端よりも小径に形成された小径部と、を有し、前記フレームは、前記釣り糸案内部と前記固定部との間に配置される連結部を有し、該連結部は、前記固定部との間に段部を形成することなく滑らかに湾曲しつつ前記釣り糸案内部に連続し、前記フレームは、筒状体の大径部の前端面に当接させた状態で、前記固定部を筒状体の受け部に一体的に固定される釣り糸ガイドを提供する。 To achieve the above object, an embodiment according to the present invention, a fixing portion fishing line guide portion is formed in the frame, fitted with the fixed portion to the receiving portion of the tubular body, rearward from the tip side of the front of the fishing rod dynamic behind the rod杆上along the original side, a fishing line guide that is held on the outer periphery of the rod rod, the tubular body is axially rearward of the receiving portion, of the cylindrical body A large-diameter portion that has a smooth curved surface-like outer peripheral surface that expands from the rear end peripheral portion of the inner hole along the axial direction toward the front front end surface, and that forms a front end surface with the receiving portion; , axially forward of the receiving portion, anda small diameter portion formed smaller in diameter than the front end of the large diameter portion, said frame is disposed between the stationary portion and the fishing line guide portion that connecting part has a, the connecting portion, the fishing smoothly curved while without forming a step portion between the fixing portion Continuously guiding portion, the frame, being in contact with the front end surface of the large diameter portion of the tubular body, to provide a fishing line guide that is integrally fixed to the fixed portion to the receiving portion of the cylindrical body .

また、前記固定部は、この連結部の側縁部に連続し、かつ前記筒状体の大径部よりも２ｍｍ以内の範囲でこの大径部から外方に突出する外周縁部を有し、この外周縁部を前記釣り糸案内部と同程度の平滑面に形成したものであってもよい。 The fixing portion has an outer peripheral edge portion that is continuous with the side edge portion of the connecting portion and protrudes outward from the large diameter portion in a range within 2 mm from the large diameter portion of the cylindrical body. The outer peripheral edge may be formed on a smooth surface comparable to the fishing line guide.

前記筒状体は、拡径した厚肉部を前端に有してもよい。 The cylindrical body may have a thickened portion with an enlarged diameter at the front end.

更に、前記大径部は、小径部よりも２倍以上の軸方向長さを有することが好ましい。 Furthermore, it is preferable that the large-diameter portion has an axial length twice or more that of the small-diameter portion.

更に、前記小径部は、受け部に装着されたフレームの前方移動を阻止する抜け止め手段を有してもよい。 Furthermore, the small diameter portion may have a retaining means for preventing the frame attached to the receiving portion from moving forward.

更に、上記の釣り糸ガイドの製造方法であって、前記フレームの固定部を、筒状体の前方に形成した小径部から挿通し、前記大径部の前端面に当接させた状態で、筒状体の受け部に固定する釣り糸ガイドの製造方法が提供される。 Furthermore, in the above method for manufacturing a fishing line guide, the fixed portion of the frame is inserted from the small diameter portion formed in front of the cylindrical body, and is in contact with the front end surface of the large diameter portion. A method for manufacturing a fishing line guide to be fixed to a receiving portion of a body is provided.

本発明の釣り糸ガイドによると、筒状体の大径部が後端から前方に向けて拡径することで、筒状体の外径を大きくし、フレームの固定部との径差を小さくし、糸ガラミを防止することができ、また、後方に大径部を形成しても、前方の小径部側からフレームを固定できるので前端面に当接するフレームは大きく形成する必要がなく、フレームは、釣り糸案内部と固定部との間に配置される連結部が固定部との間に段部を形成することなく滑らかに湾曲しつつ釣り糸案内部に連続することにより、糸ガラミを防止できると共に小型化および軽量化を容易に行うことができる。 According to the fishing line guide of the present invention, the large-diameter portion of the cylindrical body expands from the rear end toward the front, thereby increasing the outer diameter of the cylindrical body and reducing the difference in diameter from the fixed portion of the frame. In addition, it is possible to prevent thread glare, and even if a large-diameter portion is formed at the rear, it is possible to fix the frame from the front-side small-diameter portion side, so there is no need to make a large frame that contacts the front end surface. The connecting portion disposed between the fishing line guide portion and the fixed portion can be prevented from being garbled by continuing to the fishing line guide portion while smoothly curving without forming a step portion between the fixed portion and the fixed portion. It is possible to easily reduce the size and weight.

この筒状体の大径部が滑らかな湾曲面状の外周面を有する場合には、より確実に糸ガラミを防止することができる。 When the large-diameter portion of the cylindrical body has a smooth curved outer peripheral surface, it is possible to prevent yarn glare more reliably.

また、フレームの固定部が、大径部よりも外方に突出する外側部を釣り糸案内部と同程度の平滑面に形成されている場合には、この外側部で釣り糸が滑り易く、より確実に糸ガラミを防止することができる。 In addition, when the outer part of the frame fixing part is formed on the same smooth surface as the fishing line guide part, the outer part of the fixed part of the frame protrudes outward from the large-diameter part. It is possible to prevent yarn glare.

筒状体の前端に拡径した厚肉部が配置される場合には、強度を向上し、釣り竿上で安定した状態に配置することができる。 When the thick-walled portion having an enlarged diameter is disposed at the front end of the cylindrical body, the strength can be improved and the tube can be disposed in a stable state on the fishing rod.

筒状体の小径部は受け部に一体的に固定された固定部の抜け止め部を形成しており、筒状体の大径部がこの小径部よりも２倍以上の軸方向長さを有する場合には、筒状体の前後における形状および強度をバランスさせ、全体のバランスを好適に維持しつつ強度向上を図ることができる。 The small diameter portion of the cylindrical body forms a retaining portion of a fixed portion that is integrally fixed to the receiving portion, and the large diameter portion of the cylindrical body has an axial length that is at least twice as long as this small diameter portion. When it has, the shape and intensity | strength before and behind a cylindrical body can be balanced, and intensity | strength improvement can be aimed at maintaining the whole balance suitably.

フレームの前方移動を阻止する抜け止め手段を小径部に設けることにより、フレームに大きな負荷が作用しても、筒状体から脱落するのを防止できる強度を確保し、安定化を図ることができる。 By providing a retaining means for preventing the frame from moving forward at the small diameter portion, it is possible to secure the strength to prevent the frame from falling off even if a large load acts on the frame, and to stabilize the frame. .

また、上記の釣り糸ガイドの製造方法によると、フレームを筒状体の受け部に前方から圧入することで、糸ガラミを確実に防止することのできる釣り糸ガイドを容易に製造することができる。 Further, according to the above-described method for manufacturing a fishing line guide, a fishing line guide that can reliably prevent line glare can be easily manufactured by press-fitting the frame into the receiving portion of the cylindrical body from the front.

図１から図４は、本発明の好ましい実施形態による釣り糸ガイド１０を示す。 1-4 show a fishing line guide 10 according to a preferred embodiment of the present invention.

本実施形態の釣り糸ガイド１０は、釣り竿の竿杆８（図３）の外面に釣り糸ｔが付着するのを防止する外ガイドとして形成してあり、僅かな勾配を形成された竿杆８の外周上を、前方の穂先側８ａから後方の元側８ｂに沿って、竿杆８の軸線Ｃと平行な軸方向に前後動し、所要位置に摩擦力で保持することができる。必要な場合には、接着剤等の適宜の固定手段により、所要位置に移動不能に固定することも可能である。 The fishing line guide 10 of the present embodiment is formed as an outer guide for preventing the fishing line t from adhering to the outer surface of the fishing rod 8 (FIG. 3), and the outer periphery of the fishing rod 8 formed with a slight gradient. The upper part can be moved back and forth in the axial direction parallel to the axis C of the rod 8 from the front tip side 8a to the rear base side 8b, and held at a required position by a frictional force. If necessary, it can be fixed to a required position so as to be immovable by an appropriate fixing means such as an adhesive.

この釣り糸ガイド１０は、竿杆挿入孔として滑らかな内周面を有する内孔１２ａを軸方向に貫通させた筒状体１２に、金属製フレーム１４を装着し、この内孔１２ａに挿通した竿杆８上を所要位置に移動し、フレーム１４に形成した釣り糸案内部１６を介して釣り糸ｔを案内する。必要な場合には、竿杆８の好適位置に、筒状体１２を固定するための大径化部（図示しない）を形成してもよい。 This fishing line guide 10 has a metal frame 14 attached to a cylindrical body 12 that has an inner hole 12a having a smooth inner peripheral surface as a rod insertion hole, and is inserted through the inner hole 12a. The fishing line t is moved to the required position on the rod 8 and the fishing line t is guided through the fishing line guide 16 formed on the frame 14. If necessary, a large diameter portion (not shown) for fixing the cylindrical body 12 may be formed at a suitable position of the flange 8.

本実施形態のフレーム１４は、釣り糸を案内するリング状の釣り糸案内部１６と、筒状体１２に固定するリング状の固定部１８とを連結部２０で一体化した板状に形成してある。この連結部２０は、ほぼ中央部位に、軽量化を図る開口２１を形成し、側縁部２０ａ，２０ｂは、固定部１８から釣り糸案内部１６の外端に向けて次第に幅が狭まる滑らかな凹曲線あるいは凹曲面で形成し、大きさの異なる釣り糸案内部１６と固定部１８とを滑らかに連結する。このフレーム１４の釣り糸案内部１６、固定部１８および連結部２０の外周に沿う縁部は、釣り糸ガラミを防止するため、全体にわたって板厚方向にも丸みを付けられ、同様に、開口２１の周縁部も、板厚方向に丸みを付けてある。 The frame 14 of this embodiment is formed in a plate shape in which a ring-shaped fishing line guide portion 16 that guides a fishing line and a ring-shaped fixing portion 18 that is fixed to the tubular body 12 are integrated by a connecting portion 20. . The connecting portion 20 is formed with an opening 21 for lightening at a substantially central portion, and the side edge portions 20a and 20b are smooth recesses whose width gradually decreases from the fixing portion 18 toward the outer end of the fishing line guide portion 16. The fishing line guide part 16 and the fixing part 18 which are formed of a curved line or a concave curved surface and have different sizes are smoothly connected. The edges along the outer periphery of the fishing line guide portion 16, the fixing portion 18, and the connecting portion 20 of the frame 14 are rounded in the plate thickness direction throughout to prevent fishing line glare. The part is also rounded in the thickness direction.

連結部２０の上方に配置される釣り糸案内部１６は、固定部１８に対して軸方向の前方に向けて傾斜し、軸線Ｃに垂直に配置される固定部１６との間に角度θを形成する。また、釣り糸案内部１６を支える連結部２０は、固定部１８との間に段部を形成することなく、滑らかに湾曲しつつ釣り糸案内部１６に連続し、釣り糸案内部１６と共に、釣り糸を前方に案内し易くしてある。この角度θは、釣り糸ガラミを防止できるものであれば、例えば５°〜４５°、好ましくは１５°〜４５°の範囲で適宜に設定することができる。この釣り糸ガイド１０の角度θは、穂先側よりも元側で小さくし、図示しない魚釣用リールに近い側で、ガイド孔１６ａの開口面積を大きくしてもよい。 The fishing line guide portion 16 disposed above the connecting portion 20 is inclined forward in the axial direction with respect to the fixed portion 18 and forms an angle θ with the fixed portion 16 disposed perpendicular to the axis C. To do. Further, the connecting portion 20 that supports the fishing line guide portion 16 does not form a step portion with the fixed portion 18 and continues to the fishing line guide portion 16 while smoothly curving, and the fishing line is forwarded together with the fishing line guide portion 16. It is easy to guide to. The angle θ can be appropriately set within a range of, for example, 5 ° to 45 °, preferably 15 ° to 45 ° as long as fishing line glare can be prevented. The angle θ of the fishing line guide 10 may be smaller on the base side than on the tip side, and the opening area of the guide hole 16a may be increased on the side closer to the fishing reel (not shown).

このフレーム１４は、釣り糸案内部１６に形成した円形状のガイド孔１６ａを、釣り糸が引っ掛かり難い滑らかな曲面状の釣り糸案内面２２で囲んである。この釣り糸案内面２２は、例えばガイド孔１６ａの周部をカーリング加工する等、適宜の方法により、フレーム１４と一体の突部２４の内面側で形成することもできる。あるいは、セラミックス製等の他の硬質材で形成したリング部材等をガイド孔１６ａに取付けることも可能である。いずれの場合も、釣り糸案内面２２は、フレーム１４の後方側の側面から、突部２４の前端を介して前方側の側面まで、滑らかに連続する曲面状に形成することが好ましい。 The frame 14 surrounds a circular guide hole 16a formed in the fishing line guide portion 16 with a smooth curved fishing line guide surface 22 that is difficult to catch the fishing line. The fishing line guide surface 22 can also be formed on the inner surface side of the protrusion 24 integral with the frame 14 by an appropriate method such as curling the peripheral portion of the guide hole 16a. Or it is also possible to attach the ring member etc. which were formed with other hard materials, such as ceramics, to the guide hole 16a. In any case, the fishing line guide surface 22 is preferably formed in a smoothly continuous curved surface from the rear side surface of the frame 14 through the front end of the protrusion 24 to the front side surface.

連結部２０の下方に配置される固定部１８は、筒状体１２の受け部（後述する）に装着し、この受け部に一体的に固定されるために、円形状の装着孔１８ａを有し、この装着孔１８の周部の一部に、回り止め凹部１８ｂを形成してある。この固定部１８は、装着孔１８の周部に、例えばバーリング加工した突部２６を形成してあり、筒状体１２の受け部との接触面積を増大し、筒状体１２の受け部に安定した状態で保持される。また、外周縁部２８は、後述する筒状体１２の大径部と同径又は僅かに大きな外径を有し、筒状体１２の受け部に装着したときに、大径部よりも２ｍｍ以内の範囲、好ましくは釣り糸ｔの径の半分以下の大きさだけ突出する。この外周縁部２８の周面が上述のようにフレーム１４の板厚方向に丸みを付けた曲面状に形成されているため、筒状体１２から突出した場合でも、釣り糸が絡まり難い状態に配置される。 The fixing portion 18 disposed below the connecting portion 20 is attached to a receiving portion (described later) of the cylindrical body 12, and has a circular mounting hole 18a to be integrally fixed to the receiving portion. In addition, an anti-rotation recess 18 b is formed in a part of the peripheral portion of the mounting hole 18. The fixing portion 18 has, for example, a burring projection 26 formed on the peripheral portion of the mounting hole 18 to increase the contact area with the receiving portion of the cylindrical body 12, and to the receiving portion of the cylindrical body 12. It is held in a stable state. The outer peripheral edge portion 28 has an outer diameter that is the same as or slightly larger than that of the large-diameter portion of the cylindrical body 12 described later, and is 2 mm larger than that of the large-diameter portion when mounted on the receiving portion of the cylindrical body 12. It protrudes by a size within the range, preferably less than half of the diameter of the fishing line t. Since the peripheral surface of the outer peripheral edge portion 28 is formed in a curved surface rounded in the thickness direction of the frame 14 as described above, even when protruding from the cylindrical body 12, the fishing line is not easily entangled. Is done.

このように形成されるフレーム１４は、例えばマグネシウム、ステンレス鋼、チタン、チタン合金、アルミニウム、アルミニウム合金等の金属、繊維強化樹脂（ＦＲＰ）又は繊維強化金属（ＦＲＭ）等の適宜の材料で形成することができる。そして、外部に露出する部分、特に釣り糸案内部１６、連結部２０、固定部１８の外周縁部２８、釣り糸案内面２２、開口２１の内周面、および、フレーム１４の周側面を鏡面研磨し、釣り糸の引っかかり、絡みを防止する状態とすることが好ましい。特に、固定部１８の外周縁部２８を釣り糸案内部１６と同程度の平滑面に形成する場合は、この外周縁部２８が筒状体１２から径方向外方に突出しても、この外周縁部２８で釣り糸が係止されることはなく、糸ガラミを確実に防止することができる。 The frame 14 thus formed is formed of an appropriate material such as metal such as magnesium, stainless steel, titanium, titanium alloy, aluminum, and aluminum alloy, fiber reinforced resin (FRP), or fiber reinforced metal (FRM). be able to. The portions exposed to the outside, in particular, the fishing line guide portion 16, the connecting portion 20, the outer peripheral edge portion 28 of the fixing portion 18, the fishing line guide surface 22, the inner peripheral surface of the opening 21, and the peripheral side surface of the frame 14 are mirror-polished. It is preferable to prevent the fishing line from getting caught and entangled. In particular, when the outer peripheral edge portion 28 of the fixed portion 18 is formed on a smooth surface similar to the fishing line guide portion 16, even if the outer peripheral edge portion 28 protrudes radially outward from the cylindrical body 12, The fishing line is not locked by the portion 28, and it is possible to surely prevent thread glare.

図４に示すように、このフレーム１４を支える筒状体１２は、後方に配置される大径部と、フレーム１４の固定部１８を装着する受け部３２と、前方に配置される小径部３４とを有し、受け部３２の周部に、フレーム１４に形成した回り止め凹部１８ｂに嵌合する回り止め突起３６を形成してある。図示の実施形態では、回り止め凹部１８ｂおよび回り止め突起３６をそれぞれ１つずつ形成してあるが、複数設けることも可能なことは明らかである。 As shown in FIG. 4, the cylindrical body 12 that supports the frame 14 includes a large-diameter portion disposed at the rear, a receiving portion 32 for mounting the fixing portion 18 of the frame 14, and a small-diameter portion 34 disposed at the front. In the peripheral portion of the receiving portion 32, a detent projection 36 that fits in the detent recess portion 18b formed in the frame 14 is formed. In the illustrated embodiment, each of the anti-rotation recess 18b and the anti-rotation protrusion 36 is formed one by one, but it is obvious that a plurality of anti-rotation recesses 18b and anti-rotation protrusions 36 can be provided.

大径部３０は、内孔１２ａの後端周縁部から前方に向けて拡径する滑らかな湾曲面状の外周面すなわち楕円球状又は球状に湾曲する球面状部３０ａを後側に有し、この球面状部３０ａに連続する円筒状部３０ｂを前側に有する。球面状部３０ａの後端は、内孔１２ａの後端周縁部に連続することにより、竿杆８に装着したときに、この竿杆８の外周面との間に、少なくとも釣り糸ｔを係止する大きさの段部を形成することはない。また、球面状部３０ａの前部に形成去れる円筒状部３０ｂは、受け部３２との間に軸線Ｃにほぼ垂直な前端面３８を形成し、受け部３２に装着したフレーム１４の固定部１８の後側の側面を、この前端部３８に当接させた状態で保持することができる。 The large-diameter portion 30 has, on the rear side, a smooth curved surface-like outer peripheral surface that expands from the rear end peripheral portion of the inner hole 12a toward the front, that is, an elliptical spherical shape or a spherically curved spherical portion 30a. A cylindrical portion 30b continuous to the spherical portion 30a is provided on the front side. The rear end of the spherical portion 30a is continuous with the rear peripheral edge of the inner hole 12a, so that at least the fishing line t is locked with the outer peripheral surface of the rod 8 when it is attached to the rod 8. No stepped portion is formed. Further, the cylindrical portion 30b formed at the front portion of the spherical portion 30a forms a front end surface 38 substantially perpendicular to the axis C between the receiving portion 32 and the fixing portion of the frame 14 attached to the receiving portion 32. The rear side surface 18 can be held in contact with the front end portion 38.

フレーム１４の固定部１８を装着して一体的に固定する受け部３２は、固定部１８を突部２６と共に強固に保持する構造を備えており、小径部３４は後方に向けて僅かに拡径し、受け部３２に圧入された状態の固定部１８の抜け止め部を形成する。ここに、固定部１８と受け部３２とを一体的に固定することは、フレーム１４の固定部１８を受け部３２に圧入嵌合すること、嵌合接着すること、又はこれらの組み合わせにより、取れたり外れたりしない状態とすることをいう。 The receiving portion 32 that attaches and fixes the fixing portion 18 of the frame 14 integrally has a structure that firmly holds the fixing portion 18 together with the protrusion 26, and the small-diameter portion 34 slightly increases in diameter toward the rear. Then, the retaining portion of the fixing portion 18 that is press-fitted into the receiving portion 32 is formed. Here, the fixing portion 18 and the receiving portion 32 can be fixed integrally by press-fitting to the receiving portion 32, fitting and adhering to the receiving portion 32, or a combination thereof. It means that it is in a state where it does not come off.

この抜け止め部を形成する小径部３４は、例えば前端から後方に向けて僅かに拡径した厚肉部で形成することができる。また、受け部３２よりも小径に形成し、外周に複数の突条を形成してもよい。 The small-diameter portion 34 that forms the retaining portion can be formed, for example, as a thick-walled portion that is slightly expanded in diameter from the front end toward the rear. Moreover, it may form smaller diameter than the receiving part 32 and may form a some protrusion on the outer periphery.

いずれの場合も、フレーム１４の前方移動を阻止する抜け止め手段を小径部３４に設けることにより、フレーム１４に大きな負荷が作用しても、筒状体１２から脱落するのを防止できる強度を確保し、安定化を図ることができる。また、小径部３４から受け部３２にフレーム１４の固定部１８を圧入する際、受け部３２に形成した回り止め突起３６に大きな負荷が作用することはなく、フレーム１４を確実に保持することができる。 In any case, by providing the small-diameter portion 34 with a retaining means for preventing the frame 14 from moving forward, even if a large load is applied to the frame 14, the strength that prevents the frame 14 from falling off is ensured. And stabilization can be achieved. Further, when the fixing portion 18 of the frame 14 is press-fitted from the small diameter portion 34 to the receiving portion 32, a large load does not act on the anti-rotation protrusion 36 formed on the receiving portion 32, and the frame 14 can be securely held. it can.

この筒状体１２に、フレーム１４を装着する場合は、図４に示すように、筒状体１２の内孔１２ａと固定部１８の装着孔１８ａを軸方向に整合させ、前方の小径部３４から挿通する。フレーム１４の回り止め凹部１８ｂと受け部３２に形成した回り止め突起３６とを互いに軸方向に整合させた状態で、小径部３４上に圧入し、この小径部３４を越えて受け部３２上に押し込み、固定部１８の後側の側面を大径部３０の前端面３８に当接させる。 When the frame 14 is mounted on the cylindrical body 12, as shown in FIG. 4, the inner hole 12a of the cylindrical body 12 and the mounting hole 18a of the fixing portion 18 are aligned in the axial direction, and the small-diameter portion 34 on the front side is aligned. Insert through. The rotation stop recess 18b of the frame 14 and the rotation stop projection 36 formed on the receiving portion 32 are axially aligned with each other and are press-fitted onto the small-diameter portion 34, and beyond the small-diameter portion 34, onto the receiving portion 32. The rear side surface of the fixing portion 18 is brought into contact with the front end surface 38 of the large-diameter portion 30.

これにより、フレーム１４は、小径部３４で筒状体１２上に抜け止めされた状態で保持され、糸ガラミを確実に防止することのできる釣り糸ガイド１０を容易に製造することができる。この小径部３４は、フレーム１４の抜け止めとして作用することに加え、受け部３２から前方に突出することで、この筒状体１２の強度を向上し、釣り竿の竿杆８に装着した際に安定した状態で保持することができる。この小径部３４と大径部３０との軸方向長さは、大径部３０が小径部３４よりも２倍以上の軸方向長さとすることが好ましく、この場合には、筒状体１２の前後における形状および強度をバランスさせ、全体のバランスを好適に維持しつつ強度向上を図ることができる。 Thereby, the frame 14 is held in a state where it is prevented from coming off on the tubular body 12 by the small-diameter portion 34, and the fishing line guide 10 that can reliably prevent line glare can be easily manufactured. The small-diameter portion 34 acts as a retaining member for the frame 14 and protrudes forward from the receiving portion 32, thereby improving the strength of the cylindrical body 12 and when mounted on the fishing rod 8. It can be held in a stable state. The axial length of the small-diameter portion 34 and the large-diameter portion 30 is preferably set such that the large-diameter portion 30 has an axial length that is twice or more that of the small-diameter portion 34. It is possible to balance the shape and strength in the front and back, and to improve the strength while maintaining the overall balance appropriately.

このように形成された釣り糸ガイド１０は、筒状体１２の大径部３０が後端から前方に向けて拡径することで、筒状体１２の外径を大きくし、フレーム１４の固定部１８との径差を、例えば釣り糸の径の半分以下まで小さくすることができ、糸ガラミを防止することができる。また、後方に大径部３０を形成しても、前端面３８に当接するフレーム１４の固定部１８はこれよりも小径の受け部３２に装着されるため、大頚部３０に対応させて大きく形成する必要がなく、小型化および軽量化を容易に行うことができる。 The fishing line guide 10 formed in this way increases the outer diameter of the cylindrical body 12 by increasing the diameter of the large diameter portion 30 of the cylindrical body 12 from the rear end toward the front, thereby fixing the fixed portion of the frame 14. The diameter difference from 18 can be reduced to, for example, half or less of the diameter of the fishing line, and yarn glare can be prevented. Even if the large-diameter portion 30 is formed on the rear side, the fixing portion 18 of the frame 14 that contacts the front end surface 38 is attached to the receiving portion 32 having a smaller diameter than the front-end surface 38. Therefore, it is possible to easily reduce the size and weight.

図５から図８は、他の実施形態による釣り糸ガイド１１０を示す。なお、以下に説明する実施形態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１００番台の同様な符号を付し、その詳細な説明を省略する。 5 to 8 show a fishing line guide 110 according to another embodiment. In addition, since the embodiment described below is basically the same as the above-described embodiment, the same reference numerals in the 100s are assigned to the same parts, and the detailed description thereof is omitted.

図５および図６に示すように、この実施形態のフレーム１１４は、釣り糸案内部１１６を固定部１１８よりも大径に形成してあり、連結部１２０の側縁部１２０ａ，１２０ｂは上方に向けて幅が拡大する直線状に形成してある。 As shown in FIGS. 5 and 6, the frame 114 of this embodiment has the fishing line guide portion 116 formed with a larger diameter than the fixed portion 118, and the side edge portions 120 a and 120 b of the connecting portion 120 face upward. It is formed in a straight line whose width increases.

釣り糸案内部１１６の突部１２４がフレーム１１４の前側側面から突出する突出量ｄ１は、固定部１１８の突部１２６の突出量ｄ２よりも大きく形成してあり、フレーム１１４の後側の側面から前端まで、軸方向に沿って滑らかにカールした曲面状の広い釣り糸案内面１２２を形成する。また、突部１２４の外径は、符号ｒで示すように釣り糸案内部１１６の頂部の外径よりも小さく形成してあり、フレーム１１４との間に微小凹部１２５を形成する。このような突部１２４により、糸ガカリを確実に防止することのできる案内面１２２の加工性を向上することができる。 The protrusion amount d1 of the protrusion 124 of the fishing line guide 116 protruding from the front side surface of the frame 114 is formed to be larger than the protrusion amount d2 of the protrusion 126 of the fixed portion 118. Thus, the curved fishing line guide surface 122 that is smoothly curled along the axial direction is formed. Further, the outer diameter of the protrusion 124 is smaller than the outer diameter of the top of the fishing line guide portion 116 as indicated by the symbol r, and a minute recess 125 is formed between the projection 114 and the frame 114. Such protrusions 124 can improve the workability of the guide surface 122 that can reliably prevent yarn cracking.

また、固定部１１８の突部１２６は、フレーム１１４から前方に突出する筒状構造を有しており、例えばバーリング加工により形成することができる。軸方向に長い筒状構造に形成することにより、筒状体１１２上に安定した状態で保持することができる。装着孔１１８ａの後端部には、後方に向けて拡径する曲面状の案内面１１８ｃを形成してあり、筒状体１１２の小径部１３４を滑らかに案内することができる。 Further, the protrusion 126 of the fixing portion 118 has a cylindrical structure protruding forward from the frame 114, and can be formed by, for example, burring. By forming the cylindrical structure long in the axial direction, the cylindrical body 112 can be stably held. A curved guide surface 118c whose diameter increases toward the rear is formed at the rear end portion of the mounting hole 118a, and the small diameter portion 134 of the cylindrical body 112 can be smoothly guided.

図７に示すように、筒状体１１２は、大径部１３０が球面状部１３０ａと円筒状部１３０ｂとの間に、円錐状部１３０ｃを配置してあり、この円錐状部は、球面状部１３０ａから拡径しつつ円筒状部１３０まで滑らかに連続する円錐状面を形成する。このため、円筒状部１３０ｂの軸方向寸法は球面状部１３０ａよりも短く形成してある。本実施形態では、円錐状部１３０ｃが大径部１３０上で最も大きな領域を占めている。 As shown in FIG. 7, in the cylindrical body 112, the large-diameter portion 130 has a conical portion 130c disposed between the spherical portion 130a and the cylindrical portion 130b, and the conical portion has a spherical shape. A conical surface smoothly extending from the portion 130a to the cylindrical portion 130 while being expanded in diameter is formed. For this reason, the axial direction dimension of the cylindrical part 130b is formed shorter than the spherical part 130a. In the present embodiment, the conical portion 130 c occupies the largest area on the large diameter portion 130.

受け部１３２は、フレーム１１４の固定部１１８とほぼ等しい軸方向寸法を有し、回り止め突起１３６を、固定部１１８の回り止め凹部１１８ｂに嵌合することで、筒状体１１２とフレーム１１４との相対回転を確実に防止する。 The receiving portion 132 has an axial dimension substantially equal to that of the fixing portion 118 of the frame 114, and the cylindrical body 112 and the frame 114 are fitted by fitting the anti-rotation protrusion 136 into the anti-rotation recess 118 b of the fixing portion 118. Reliably prevent relative rotation of

また、小径部１３４は、前端に形成したテーパ面１３４ａと、後端に形成した厚肉部１３４ｂとを有する。この厚肉部１３４ｂは受け部１３２よりも僅かに大径に拡径した円筒状面を有し、回り止め突起１３６の外端面に連続する。厚肉部１３４ｂは、固定部１１８の突起１２６の前端面に当接し、フレーム１１４の抜け止めとして作用する。 Moreover, the small diameter part 134 has the taper surface 134a formed in the front end, and the thick part 134b formed in the rear end. The thick portion 134b has a cylindrical surface that is slightly larger in diameter than the receiving portion 132, and is continuous with the outer end surface of the anti-rotation protrusion 136. The thick part 134b abuts on the front end surface of the protrusion 126 of the fixed part 118 and acts as a retaining member for the frame 114.

この小径部１３４の前端部は、大径部１３０の球状面部１３０ａよりも大径に形成してあり、軸線Ｃに対して垂直な環状端面１３５を形成する。 The front end portion of the small diameter portion 134 has a larger diameter than the spherical surface portion 130 a of the large diameter portion 130, and forms an annular end surface 135 that is perpendicular to the axis C.

この筒状体１１２にフレーム１１４を装着する場合も、図７に示すように、筒状体１１２の内孔１１２ａと固定部１１８の装着孔１１８ａを軸方向に整合させ、前方の小径部１３４から挿通する。テーパ面１３４ａが装着孔１１８ａの案内面１１８ｃで案内される。フレーム１１４の回り止め凹部１１８ｂと受け部１３２に形成した回り止め突起１３６とを互いに軸方向に整合させた状態で、固定部１１８を小径部１３４上に圧入し、この小径部１３４の厚肉部１３４ｂを越えて受け部１３２上に押し込み、固定部１１８の後側の側面を大径部１３０の前端面１３８に当接させる。 Even when the frame 114 is mounted on the cylindrical body 112, as shown in FIG. 7, the inner hole 112a of the cylindrical body 112 and the mounting hole 118a of the fixing portion 118 are aligned in the axial direction, Insert. The tapered surface 134a is guided by the guide surface 118c of the mounting hole 118a. The fixing portion 118 is press-fitted onto the small-diameter portion 134 with the anti-rotation concave portion 118b of the frame 114 and the anti-rotation projection 136 formed on the receiving portion 132 aligned with each other in the axial direction. It is pushed over the receiving part 132 beyond 134 b and the rear side surface of the fixing part 118 is brought into contact with the front end face 138 of the large diameter part 130.

これにより、フレーム１１４は、小径部１３４で筒状体１１２上に抜け止めされた状態で保持され、糸ガラミを確実に防止することのできる釣り糸ガイド１１０を容易に製造することができる。この小径部１３４は、フレーム１１４の抜け止めとして作用することに加え、球状面部１３０ａ大きな外径を有して受け部１３２から前方に突出することで、この筒状体１１２の強度を向上し、釣り竿の竿杆８に装着した際に安定した状態で保持することができる。 As a result, the frame 114 is held in a state where the frame 114 is prevented from coming off on the cylindrical body 112 by the small diameter portion 134, and the fishing line guide 110 that can surely prevent line glare can be easily manufactured. In addition to acting as a retaining member for the frame 114, the small diameter portion 134 has a large outer diameter with the spherical surface portion 130a and protrudes forward from the receiving portion 132, thereby improving the strength of the cylindrical body 112. When mounted on the fishing rod 8, it can be held in a stable state.

前記フレーム１４，１１４に炭素ドープ酸化チタン層を形成するとよい。これにより、フレーム自体の表面硬度を高くでき、耐磨耗性を向上できる。また、フレーム１４，１１４自体に層を形成できるので、メッキ等のように剥離が発生することもない。 A carbon-doped titanium oxide layer may be formed on the frames 14 and 114. Thereby, the surface hardness of the frame itself can be increased, and the wear resistance can be improved. Further, since layers can be formed on the frames 14 and 114 themselves, peeling does not occur unlike plating.

なお、本発明は、上述の実施形態に限るものではなく、これらの実施形態を様々に組合せあるいは変形することが可能である。例えばフレーム１４に筒状体１１２を組合せ、あるいは、フレーム１１４に筒状体１２を組み合わせることも可能である。
