Description

[Technical field]

[0001] The present invention relates to a top guide that is attached to the tip of a fishing rod's tip section, and to a fishing rod equipped with such a top guide. [Background technology]

[0002] A fishing rod to which a fishing reel is attached is equipped with a fishing line guide through which the fishing line that is reeled out from the fishing reel is inserted. A top guide is attached to the tip of the tip of the fishing line guide, and the top guide has a fitting hole into which the tip of the tip is pressed and fixed. For example, Patent Document 1 discloses a structure in which a rod insertion hole is formed in the main body of the top guide, the opening area of ​​the rod insertion hole into which the tip of the rod is inserted is made to have a large diameter structure, and a flexible material (adhesive) is filled between this large diameter part and the tip of the rod to fix the top guide. Patent Document 1 also discloses a structure in which a hole with a diameter smaller than the diameter of the tip of the rod is formed at the tip of the insertion hole, and when a solid tip of the rod is inserted into the fitting hole, air escapes and the rod is easily inserted. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2002-095388 Summary of the Invention [Problem to be solved by the invention]

[0004] The top guide of the above structure allows air to escape when the tip rod is inserted, making it easy to insert, but the adhesive strength between the rod surface is weak, so there is a possibility that the top guide may come off.

[0005] The present invention has been made in response to the above-mentioned problems, and aims to provide a top guide having a structure that makes it difficult for it to come off the tip rod, and a fishing rod equipped with such a top guide. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the top guide of the present invention comprises a main body having a through hole into which a tip rod is inserted and filled with adhesive, and a fishing line insertion section which is integrally formed with the main body and through which a fishing line is inserted, the through hole comprising: a first pipe section having a reduced diameter section which reduces in diameter from the opening into which the tip rod is inserted towards the tip side; and a second pipe section which is located further forward than the stop position where the tip rod inserted from the opening stops against the reduced diameter section, and which is connected to the first pipe section and has an expanded diameter section which expands in diameter towards the tip side.

[0007] The top guide of the above configuration is fixed to the tip rod by applying adhesive near the opening of the first pipe section and / or the outer peripheral surface of the tip of the tip rod and fitting the tip rod into the opening of the first pipe section in this state. When the tip rod is fitted, air escapes to the outside through the second pipe section, so the adhesive flows through the reduced diameter section to the second pipe section on the tip side of the position where the tip rod stops. There is a gap between the inner surface of the first pipe section and the outer peripheral surface of the tip rod due to the reduced diameter section, and the adhesive is filled evenly therein, ensuring the adhesive strength. In addition, the excess adhesive is smoothly pushed out and filled in the second pipe section that is connected to the first pipe section and expands in diameter toward the tip, enhancing the anchor effect and improving the adhesive strength of the top guide.

[0008] In addition, in order to achieve the above-mentioned object, the top guide of the present invention has a main body having a through hole into which a tip rod is inserted and filled with adhesive, and a fishing line insertion portion which is integrally formed with the main body and through which a fishing line is inserted, the through hole narrowing in diameter from the opening into which the tip rod is inserted towards the tip side, and having a narrowing portion against which the tip edge of the tip rod abuts and stops, and a recess formed in the tip surface of the main body and communicating with the narrowing portion.

[0009] In the top guide of the above configuration, adhesive is applied near the opening of the through hole and / or to the outer peripheral surface of the tip of the tip rod, and in this state, the tip rod is fitted into the opening. When the tip rod is fitted, air escapes to the outside through the recess, so the adhesive flows through the reduced diameter portion to the recess further forward than the position where the tip rod stops. A gap is created between the reduced diameter portion and the outer peripheral surface of the tip rod by the reduced diameter portion, and the adhesive is filled evenly therein, ensuring adhesive strength. In addition, excess adhesive is smoothly pushed out and filled in the recess communicating with the reduced diameter portion, enhancing the anchor effect and improving the adhesive strength of the top guide.

[0010] Furthermore, the present invention is characterized in that a top guide constructed as described above is adhesively fixed to the tip of a rod tip. Effect of the Invention

[0011] According to the present invention, it is possible to obtain a top guide having a structure that makes it difficult for it to come off from the tip rod, and a fishing rod in which the top guide is difficult to come off. [Brief description of the drawings]

[Figure 6] 1(a) to 1(e) are views showing other embodiments of the top guide (second to sixth embodiments), respectively. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The fishing rod 1 shown in FIG. 1 is configured as a telescopic rod in which a middle rod 5 and a tip rod 7 are housed in a butt rod 3 and are sequentially telescopically joined. Each rod is configured as a tubular body, and is produced by a known manufacturing method, such as winding a prepreg sheet made of fiber-reinforced resin in which reinforced fibers are impregnated with synthetic resin. In this case, the rods constituting the fishing rod of the present invention, particularly the tip rod, may have a solid structure other than the tubular structure. The number of rods housed inside the butt rod 3 (the number of joints) is optional, and the joining method may be a parallel joint type, a spigot joint type, or the like, other than a telescopic type. The fishing rod may also be a single rod, rather than a rod in which multiple rods are joined.

[0014] A reel seat 8 having a reel leg mounting portion is disposed on the base end side of the butt rod 3. A fixed hood and a movable hood are provided on both axial sides of the reel leg mounting portion of this reel seat 8, and by mounting the reel leg of a fishing reel 100 on the reel leg mounting portion and moving the movable hood in the axial direction, the reel leg is fastened and fixed onto the reel leg mounting portion.

[0015] A number of line guides 9 for guiding the fishing line are attached at regular intervals in the axial direction to the butt rod 3, middle rod 5 and tip rod 7, and a top guide 10 (described later) is attached to the tip of the tip rod. The line guides 9 may include a type (floating guide) that can slide along the surface of the rod when it is stored.

[0016] Next, the configuration of the top guide 10 attached to the tip of the tip rod 7 will be described with reference to Figs.

[0017] The top guide 10 is integrally formed from, for example, resin or ceramic, and has a cylindrical main body 11 and a fishing line insertion portion 20 that is integrally provided with the main body 11 and through which a fishing line is inserted. The fishing line insertion portion 20 of this embodiment has a pair of walls 21 that rise gradually forward from both sides of the main body 11, and the front upper ends of the pair of walls are connected by a connecting portion 22, and the fishing line insertion portion 20 is formed into a ring shape by the pair of walls 21 and the connecting portion 22.

[0018] The shape of the fishing line insertion portion 20 is not particularly limited, and various modifications are possible, such as, for example, raising a plate-like member from the main body 11 and forming a circular opening at the upper end through which the fishing line can be inserted.

[0019] The main body 11 has a through hole 12 formed therein, into which the tip of the tip rod 7 is fitted and which is filled with adhesive. The through hole 12 may have any structure as long as it penetrates the top guide in the axial direction, and in this embodiment, it has a first pipe section 13 with a reduced diameter section 13a that reduces in diameter toward the tip from the opening 12a into which the tip rod 7 is inserted, and a second pipe section 14 that is located further forward than position P where the tip rod 7 inserted from the opening 12a abuts against the reduced diameter section 13a and stops, and is connected to the first pipe section 13 and has an expanded diameter section 14a that expands in diameter toward the tip.

[0020] The reduced diameter portion 13a formed in the first pipe portion 13 in this embodiment is configured as a tapered surface that continuously reduces in diameter from the opening 12a toward the tip side, so that a gap S at an angle θ is generated between the outer circumferential surface of the tip rod 7 to be fitted and the inner surface of the reduced diameter portion 13a. In this way, by forming the reduced diameter portion 13a that reduces in diameter toward the tip in the through hole 12 of the first pipe portion 13, when the tip rod 7 is fitted, the adhesive is easily dispersed evenly in the gap S between the outer circumferential surface of the tip rod 7 and the inner surface of the reduced diameter portion 13a, and is easily moved toward the tip side. The angle θ between the reduced diameter portion 13a and the outer circumferential surface of the tip rod may be about 0.05 to 1°.

[0021] The tip edge 7a of the tip rod 7 inserted into the through hole 12 is fixed by abutting against any position of the reduced diameter section 13a of the first pipe section 13. In this embodiment, a fixed wall (bottom wall) 13A perpendicular to the axial direction of the tip rod 7 is formed at the tip of the reduced diameter section 13a so that the tip edge 7a of the tip rod 7 inserted into the first pipe section 13 is abutted against and fixed. That is, when the tip rod 7 is inserted into the reduced diameter section 13a of the through hole 12, the tip edge 7a finally abuts against it and the position is fixed. In this way, the fixing wall is formed, and thus the fixing state can be stabilized. Although a gap is generated between the leading edge 7a and the fixing wall 13A in Fig. 5, they are actually fixed in abutting contact state or with an adhesive interposed therebetween.

[0022] The second pipe section 14 adjacent to the first pipe section 13 is formed with an expanded diameter section 14a that is connected to the reduced diameter section 13a and expands in diameter toward the tip side, forming a communication hole 12. This expanded diameter section 14a is formed to have a smaller diameter than the diameter of the reduced diameter section 13a at the bottom wall 13A, and is formed so that the diameter expands toward the tip side. This expanded diameter section 14a is connected to the reduced diameter section 13a of the first pipe section 13 and functions as an air vent, and further has the function of increasing the anchor effect when fixing the tip rod 7 by being filled with adhesive.

[0023] For this reason, it is preferable that the inlet portion of the enlarged diameter portion 14a be formed with a smaller diameter than the diameter of the reduced diameter portion 13a so that the adhesive does not flow too much from the first pipe portion 13 when the tip rod is inserted and fixed, and that the diameter be formed so as to enlarge toward the tip to enhance the anchor effect.

[0024] Next, a procedure for attaching (fixing) the above-mentioned top guide 10 to the tip of the tip rod 7 will be described. When attaching the top guide 10 of the above-mentioned configuration to the tip of the tip rod 7, first, adhesive is applied to the opening 12a of the first pipe section 13 (including the through hole 12 inside it) and / or the outer peripheral surface of the tip of the tip rod 7, and in this state, the tip rod 7 is inserted into the opening 12a of the first pipe section 13.

[0025] When the tip rod 7 is inserted, air escapes to the outside through the enlarged diameter portion 14a of the second pipe section 14, so the adhesive flows through the reduced diameter portion 13a to the enlarged diameter portion 14a of the second pipe section 14, which is further forward than the position P where the tip rod 7 stops. The tip rod 7 moves in the axial direction until the tip edge 7a abuts against the bottom wall 13A, and a gap S that gradually narrows toward the tip is generated between the inner surface of the first pipe section 13 and the outer peripheral surface of the tip rod due to the angle θ generated by the reduced diameter portion, making it easier for the adhesive to be pushed out. In other words, the adhesive can be evenly distributed in this gap S, ensuring adhesive strength.

[0026] At this time, until the tip edge of the tip rod 7 reaches position P, the second pipe section 14, which is connected to the first pipe section 13 and has an expanded diameter section 14a that expands in diameter toward the tip, is smoothly extruded and filled (some of the adhesive may flow out of the expanded diameter section 14a, but this can be wiped off, etc.). In this way, the adhesive is filled into the expanded diameter section 14a, and the expanded diameter shape makes it difficult for the adhesive to come out toward the base end, thereby enhancing the anchor effect and improving the adhesive strength of the top guide 10.

[0027] After the top guide 10 is bonded to the tip of the tip rod as described above, a fixing thread 50 may be wound between the main body 11 and the outer surface of the tip rod 7, and a resin 51 or the like may be applied to increase the adhesive strength.

[0028] Next, another embodiment of the top guide will be described with reference to Figures 6(a) to (e). In the following embodiment, components similar to those in the above embodiment are given the same reference numerals and detailed description thereof will be omitted.

[0029] FIG. 6(a) is a diagram showing a second embodiment. This top guide 10A shows a configuration in which a groove 13d is formed on the inner surface of a reduced diameter portion 13a formed in a first pipe portion 13. The configuration of the groove 13d can be modified as appropriate, but it is preferable to form a plurality of grooves along the axial direction at predetermined intervals in the circumferential direction of the inner surface.

[0030] By forming such groove 13d, when the tip rod 7 is inserted into the through hole 12, the adhesive can move more easily in the axial direction and spread evenly, improving the adhesive strength. In the configuration in which the groove 13d extending in the axial direction is formed, the through hole 12 formed in the first pipe portion 13 may be formed in a straight shape.

[0031] Also, a straight through hole may be formed in the first pipe section 13 and the second pipe section 14. For example, as shown in Fig. 6(a), a straight through hole 14c may be formed on the reduced diameter section 13a side of the second pipe section 14, or other suitable modifications may be made.

[0032] FIG. 6(b) is a diagram showing a third embodiment. This top guide 10B is configured so that the boundary P1 between the first pipe section 13 and the second pipe section 14 communicates with the same inner diameter. That is, the through hole 12 is formed so as to be continuous without any step at the boundary between the reduced diameter section 13a and the expanded diameter section 14a.

[0033] With this configuration, adhesive can be easily filled into the enlarged diameter portion 14a when the tip rod is fitted, enhancing the anchor effect and improving the adhesive strength. In this configuration, the tip edge of the inserted tip rod is fixed by abutting against any position of the reduced diameter portion 13a or against the position of the boundary P1.

[0034] FIG. 6(c) is a diagram showing a fourth embodiment. In this top guide 10C, the reduced diameter portion of the first pipe portion 13 is configured with a plurality of tapered surfaces. That is, the through hole 12 in the first pipe portion 13 is configured with a plurality of tapered surfaces 13a, 13b having different taper amounts.

[0035] In this way, the configuration of the reduced diameter portion of the first pipe section 13 can be modified as appropriate, such as by forming it with multiple surfaces, and similarly, the configuration of the expanded diameter portion of the second pipe section 14 can be modified as appropriate.

[0036] FIG. 6(d) shows a fifth embodiment. This top guide 10D has a recess 18 formed in the tip surface 11A of the top guide body 11, and this recess 18 is connected to multiple reduced diameter portions 13a of the first pipe section 13 and the reduced diameter portions 13c continuing therefrom (the reduced diameter portions 13a may be straight).

[0037] Even with such a recess 18, when the tip rod 7 is inserted, the adhesive can be pushed out from the reduced diameter parts (through holes) 13a, 13b of the first pipe section 13 and pool there, so it is possible to increase the adhesive strength of the tip rod by the anchor effect. Note that, in a configuration in which such a recess 18 is formed, it is preferable to make the diameter of the bottom of the recess 18 larger than the diameter of the tip of the reduced diameter part 13c at the boundary position P5 between the tip of the reduced diameter part 13c and the bottom of the recess 18. By increasing the diameter of the bottom of the recess 18 in this manner, the adhesive is less likely to leak toward the base end side, enhancing the anchor effect and improving the adhesive strength of the top guide.

[0038] FIG. 6(e) is a diagram showing a sixth embodiment. As in the fifth embodiment, this top guide 10E has a recess 18a formed in the tip surface 11A of the main body 11 of the top guide, and this recess 18a is connected to the reduced diameter portion 13a of the first pipe portion 13 (the reduced diameter portion 13a may be straight). The bottom of this recess 18a is formed so that the diameter of the bottom of the recess 18a is larger than the diameter of the tip of the reduced diameter portion 13a at the boundary position P5 between the tip of the reduced diameter portion 13a and the bottom of the recess 18a.

[0039] The recess 18a has a smaller diameter on the opening side, but the diameter of its bottom is made larger than the diameter of the tip of the reduced diameter portion 13a, so that the adhesive is less likely to leak from the tip side and less likely to leak out to the base end side, thereby enhancing the anchor effect and improving the adhesive strength of the top guide.

[0040] According to the top guides 10, 10A to 10E configured as in the above embodiment, when the top guide is attached to the tip of the tip rod, the adhesive is filled evenly because the air is effectively removed, and the adhesive strength is ensured. In addition, since the through hole 12 of the main body 11 is tapered, the clearance does not change significantly at any part of the tip rod, and the adhesive strength is improved. In particular, when the top guide is made of ceramic, it is preferable to make it into the shape described above because the adhesiveness of ceramic is poor. In addition, when the above-mentioned top guide is made by injection molding, the pipe part is made by a pin, and the taper improves the mold release and the yield.

[0041] Furthermore, if the through hole of the second pipe section 14 and the recesses 18, 18a are shaped to widen toward the tip, air can escape more easily, and excess adhesive can accumulate in that area, enhancing the anchor effect and making it more difficult for the top guide to come off the tip rod.

[0042] In the above-mentioned top guide configuration, it is preferable to perform a roughening treatment so that the inner surface of the through hole 12 formed in the main body 11 has a surface roughness that is rougher than the surface of the main body 11. In this way, if the portion that comes into contact with the adhesive when the tip rod is inserted into the through hole 12 is roughened, the anchor effect for the adhesive is enhanced, making it possible to make the top guide less likely to come off.

[0043] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and can be practiced in various modifications without departing from the gist of the present invention. For example, the overall shape of the top guide is not particularly limited, and can be modified in various ways, such as by attaching a guide ring through which the fishing line passes, etc. Also, the through hole formed in the main body 11 can be modified as appropriate, such as by forming multiple tapered surfaces with different taper amounts continuously in the axial direction, or by forming a partially straight portion.
