Description

Technical Field

[0001] The present invention relates to a fishing rod having a solid rod, and more particularly to a fishing rod characterized by a joint structure (assembly structure) between adjacent large-diameter rods and small-diameter rods.

Background Art

[0002] Conventionally, as a fishing rod having a solid structure (also referred to as a solid structure), one composed of a single solid rod is known. A reel seat for mounting a reel is provided on the base end side of the rod, and a plurality of fishing line guides are attached along the axial direction. When such a fishing rod with a solid structure is configured as a single rod, its storage dimension becomes long and its handling property is poor. Therefore, it is known to configure it with a plurality of solid rods and provide a joint structure that joints axially at the ends of each solid rod (for example, Patent Document 1).

[0003] Patent Document 1 discloses a joint structure that enables joining of solid rods. FIG. 2 thereof discloses a joint structure in which a joint pipe (joint pipe body) exposed on the surface is disposed at the joint portion. The inner peripheral surface of the front end side of the joint pipe body and the outer peripheral surface of the rear end of the front solid rod are fixed by adhesion, and the front end side of the rear solid rod is inserted into the inner peripheral surface of the rear end side of the joint pipe body so that the solid rods are joined together.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, when joining solid rods together using a jointing tube, it is necessary to bond the outer surface of the end of the solid rod to the inner surface of one end of the jointing tube. This bonding is performed by applying adhesive to the outer surface of the end of the solid rod and moving the inner surface of one end of the jointing tube and the solid rod relative to each other in the axial direction. Since the inner diameter of the jointing tube is usually formed to be slightly larger than the outer diameter of the end of the solid rod, when the solid rod is inserted into the inner surface of the jointing tube during bonding, the applied adhesive tends to squeeze out. In this case, while excess adhesive that spills out can be wiped away, adhesive that spills out into the interior cannot be wiped away, and once it hardens, it can cause abnormal noises and poor joints.

[0006] This invention was made in view of the above-mentioned problems, and aims to provide a fishing rod having a joint structure between solid rod sections that does not produce abnormal noise or joint failure at the joint portion. [Means for solving the problem]

[0007] To achieve the above objectives, the present invention provides a fishing rod comprising a large-diameter solid rod and a small-diameter solid rod joined in the axial direction, and a joint portion for joining the two solid rods, wherein the joint portion comprises a tubular joint tube body that covers the ends of adjacent solid rods, with the outer surface of the end of one solid rod adhesively fixed to one end and the end of the other solid rod press-fitted and fixed to the other end, and characterized in that, with the edge of one solid rod pressing against the inner surface of the joint tube body, the outer surface of the end of one solid rod adhesively fixed to one end of the joint tube body such that the gap width between the inner surface of the open end of one end of the joint tube body and the outer surface of the end of one solid rod is 0.05 to 0.25 mm.

[0008] In the fishing rod configuration described above, the outer surface of one end of a solid rod is glued and fixed to the inner surface of one end of the jointed tube. In this configuration, when the end of one solid rod is inserted into the one end of the jointed tube, the edge of the end of the solid rod comes into contact with the inner surface of the jointed tube and stops. Therefore, if adhesive is applied to the outer surface of the end of one solid rod and the end of the solid rod is inserted into the inner surface of the jointed tube, the applied adhesive will not leak inside. In other words, a fishing rod can be obtained that does not produce abnormal noise or joint defects at the joint. [Effects of the Invention]

[0009] According to the present invention, a fishing rod having a joint structure between solid rod sections can be obtained that does not produce abnormal noise or joint defects at the joint portion. [Brief explanation of the drawing]

[Figure 6] A schematic diagram illustrating an example of attaching a fishing line guide to a jointed pipe. [Modes for carrying out the invention]

[0011] Figure 1 shows one embodiment of a fishing rod according to the present invention. The fishing rod 1 according to this embodiment has a structure in which two solid rods are joined together, and comprises a butt rod 3 and a tip rod 5, which are configured as solid rods. The butt rod 3 and the tip rod 5 have approximately the same axial length, and are configured as two joined rods, resulting in a long overall length that can be carried compactly. Furthermore, the tip portion 3A of the butt rod 3 and the base portion 5A of the tip rod 5 can be joined by a joint portion 10, which will be described later.

[0012] Furthermore, there is no limit to the number of solid rod sections (total number of sections), and a configuration in which three or more solid rod sections are joined together by a joint section 10 is also acceptable. In addition, in a configuration having multiple joint sections, it is sufficient that at least one joint section 10 with the configuration described later is provided.

[0013] The aforementioned base rod 3 and tip rod 5 can be formed from, for example, a solid body made of fiber-reinforced resin, and as long as they are solid structures, the constituent materials are not limited. Furthermore, as long as the joint 10 has a structure that joins the solid parts, the other parts may have tubular sections. In this embodiment, the butt rod 3 is provided with a reel seat 6A on which a reel (not shown) is attached, a trigger 6B for gripping with a finger, and a grip 6C. In addition, multiple known fishing line guides 30 are arranged at regular intervals in the axial direction on the butt rod 3 and the tip rod 5 to guide the fishing line from the reel attached to the reel seat 6A.

[0014] Next, the joint portion 10 of the fishing rod 1 described above will be explained with reference to Figures 2 to 4. Figure 2 shows an example of the configuration of the joint 10 between adjacent butt rods 3 and tip rods 5. In this embodiment, the tip 3A of adjacent butt rods 3 and the base 5A of tip rod 5 are joined together to form a tapered structure as a fishing rod. Thus, the butt rod 3 is a large-diameter solid rod, and the tip rod 5 is a small-diameter solid rod (hereinafter also referred to as the large-diameter solid rod 3 and the small-diameter solid rod 5).

[0015] The integrating part 10 includes a tubular integrating pipe body 11 that covers the ends of adjacent solid rods (the tip 3A of the large-diameter solid rod 3 and the base end 5A of the small-diameter solid rod 5). On one end side 11A of this integrating pipe body 11, the outer surface 3a of the tip 3A of the large-diameter solid rod 3 is adhesively fixed, and on the other end side 11B, the base end 5A of the small-diameter solid rod 5 is press-fitted and fixed so as to be insertable and removable.

[0016] One end side 11A of the integrating pipe body 11 has a shape that gradually expands toward the large-diameter solid rod 3 (rear end side). For this reason, the inner surface 11a of one end side 11A of the integrating pipe body 11 of the present embodiment has a tapered surface (when compared with the tip 3A of the large-diameter solid rod 3, it is a steep tapered surface), and the outer surface 3a of the tip 3A of the large-diameter solid rod 3 has a gentler tapered surface (gentle tapered surface). Regarding these tapered surfaces, when comparing the two in terms of the taper amount, it is sufficient that the integrating pipe body 11 and the large-diameter solid rod 3 have the taper of the inner surface 11a > the taper of the outer surface 3a.

[0017] Thereby, by applying an adhesive 20 to the outer surface (also referred to as a gentle tapered surface) 3a of the tip 3A of the large-diameter solid rod 3 and inserting it into the inner surface (also referred to as a steep tapered surface) 11a of the integrating pipe body 11, as shown in FIG. 2, the outer surface 3a of the tip 3A of the large-diameter solid rod 3 is adhesively fixed to one end side 11A of the integrating pipe body 11. In this case, since the outer surface 3a on the insertion side has a gentler taper than the inner surface 11a on the inserted side, when the large-diameter solid rod 3 is inserted, the edge 3b of its tip 3A abuts against the inner surface and stops (see FIGS. 3 and FIG. 2; the symbol P is the stop position). Also, in the stopped state, a gap G that gradually expands from the edge 3b toward the base end side is formed.

[0018] Regarding this gap G, at the position of the open end 11a' of the large-diameter solid rod, the gap width G1 between the inner surface 11a at the open end 11a' on one end side of the integrated pipe body 11 and the outer surface 3a of the end of the large-diameter solid rod 3 is the widest. Regarding this gap width G1, it is preferable that the outer surface 3a of the large-diameter solid rod 3 is adhesively fixed to one end side of the integrated pipe body 11 so as to be 0.05 to 0.25 mm, preferably 0.10 to 0.20 mm.

[0019] Until the large-diameter solid rod 3 stops, the adhesive 20 applied to the outer surface 3a of the tip portion 3A of the large-diameter solid rod 3 may be extruded toward the base end side of the large-diameter solid rod 3 and flow out along the outer surface 3a of the tip portion 3A as shown by the arrow D in FIG. 4. In this case, when the large-diameter solid rod 3 is inserted and fixed as described above, the adhesive 20 applied to the outer surface 3a of the tip portion 3A does not leak inside because the edge 3b abuts against the inner surface 11a. Also, when the adhesive 20 flows out along the outer surface 3a of the end of the large-diameter solid rod 3, the flowing adhesive can be wiped off. Thus, by the gradually expanding gap G and the adhesive 20 filled in the gap G as described above, the contact against the outer surface 3a of the edge 11a' portion is relaxed, and it becomes possible to suppress mouth cracking.

[0020] If the taper difference between the inner surface (steep taper surface) 11a of the integrated pipe body 11 and the outer surface (gentle taper surface) 3a of the large-diameter solid rod 3 is too large, there is a possibility that the adhesive is not sufficiently filled and poor adhesion occurs. Also, the adhesive may not spread evenly and cause poor adhesion. On the contrary, if it is made too small, there is a possibility that when the large-diameter solid rod is inserted, it is squeezed by the edge 3b and the adhesive is insufficient, resulting in poor adhesion. Specifically, the difference between the two tapers may be set within the range of 1 / 1000 to 3 / 1000.

[0021] Furthermore, regarding the bonding length L between the steeply tapered surface 11a and the gently tapered surface 3a, if it is too short, the bonding strength in the area of ​​the joint 10 will be weak, and the bonding strength may decrease when the fishing rod bends. Also, if the bonding length L is too long, it may affect the flexibility or increase the weight. For this reason, it is preferable to set the bonding length L in the range of 30 to 100 mm.

[0022] As mentioned above, it is preferable for the gap width G1 to be 0.05 to 0.25 mm. However, if the joint length L is made longer at 100 mm, it is possible to keep the gap width G1 within the range of 0.10 to 0.20 mm by configuring the taper difference to be 1 / 1000 to 2 / 1000. Also, if the joint length L is made shorter at 30 mm, it is possible to make the gap width G1 0.09 mm (within the range of 0.05 to 0.25 mm) by setting the taper difference to approximately 3 / 1000.

[0023] In this embodiment, the taper (steep taper surface) of the inner surface 11a of the jointed pipe body 11 is set to 4 / 1000, and the taper (gentle taper surface) of the outer surface 3a of the large-diameter solid rod 3 is set to 3 / 1000, resulting in a taper difference of 1 / 1000.

[0024] The joint tube 11 constituting the joint portion 10 has the base end portion 5A of the small-diameter solid rod 5 pressed and fixed to its other end 11B in a removable manner. This press-fit fixing is constructed using a tapered structure. For example, in this embodiment, as shown in Figure 2, the other end 11B of the joint tube 11 is configured to be straight, and a tapered surface formed on the base end portion 5A of the small-diameter solid rod 5 is joined to it.

[0025] In other words, the end side of the base end 5A has a straight outer surface 5a with a diameter slightly smaller than the inner surface diameter of the other end 11B of the jointed pipe body 11, and this part forms a parallel joint structure (parallel joint length L1). Furthermore, a tapered surface 5b is formed on the outer surface 5a, which gradually widens in diameter from the middle towards the tip. Therefore, when the base end 5A of the small-diameter solid rod 5 is inserted into the opening of the other end 11B of the jointed pipe body 11, the outer surface 5a slides against the inner surface 11b of the other end 11B of the jointed pipe body 11, and finally the tapered surface 5b comes into contact with the open end 11d of the other end 11B of the jointed pipe body 11, resulting in a jointed state.

[0026] Furthermore, regarding the above-mentioned joint length L1, if it is made too long, it will affect the bending (flexing) of the rod (the joint will become stiffer and harder to bend), and the weight will increase. Conversely, if it is made too short, the strength of the joint will be weakened. For this reason, it is preferable to set the joint length L1 in the range of 30 to 100 mm. In addition, in the above-mentioned jointed state, an axial gap S is formed inside the jointed pipe body 11 between the large-diameter solid rod 3 and the small-diameter solid rod 5 (more specifically, between the end edge 3b of the large-diameter solid rod 3 and the end edge 5c of the small-diameter solid rod 5). The axial length L2 of this gap S is preferably set within the range of 10 to 40 mm, because if it is too long, it will reduce strength and affect the bending of the rod (it will bend too much), and if it is too short, variations in the bonding length will cause fitting defects (the end edge 5c of the small-diameter solid rod 5 and the end edge 3b of the large-diameter solid rod 3 will come into contact).

[0027] The material of the jointed pipe 11 described above is not limited and can be made of, for example, metal, hard plastic, fiber-reinforced resin, etc. Furthermore, it is preferable to form recesses (including grooves and roughened surfaces) on the outer surface 3a of the large-diameter solid rod 3 to which the adhesive 20 is applied. For example, as shown in Figure 5(a), multiple grooves 25 may be formed along the axial length direction at predetermined intervals in the circumferential direction, or as shown in Figure 5(b), multiple grooves 26 may be formed along the circumferential direction at predetermined intervals in the axial length direction. Alternatively, as shown in Figure 5(c), a spiral groove 27 may be formed.

[0028] By forming such recesses, the anchoring effect of the adhesive is enhanced, making it possible to improve the adhesive strength. Furthermore, these recesses may also be provided on the joint pipe body 11 side.

[0029] A fishing rod equipped with the joint section 10 described above can be obtained, which has a short collapsed length and a solid structure that is easy to handle. Furthermore, when the solid rod is bonded and fixed to the joint tube 11, the adhesive 20 does not leak inside, so a fishing rod can be obtained that does not produce abnormal noise or joint defects at the joint between solid rods. In addition, since the solid rod 3, to which the adhesive 20 has been applied to the gently tapered surface 3a is inserted from the opening on the larger diameter side of the joint tube 11, the adhesion of the adhesive 20 to other places is suppressed, making it possible to achieve a clean finish.

[0030] As shown in Figure 1, the solid rod of the fishing rod 1 described above has multiple fishing line guides 30 attached along the axial direction. In this case, by attaching the fishing line guides 30 to the joint tube 11, it is possible to conceal the exposure of the joint portion and reduce the difference in diameter between the joint tube 11 and the solid rod, thereby improving the appearance.

[0031] Specifically, as shown in Figure 6, the legs 31 of the fishing line guide 30 are fixed to the boundary portion 50 between the jointed tube 11 and the solid rod 3 which is adhesively fixed to the jointed tube. As for the method of fixing the legs 31, as in the conventional method, the fishing line guide can be placed so that the legs 31 straddle the boundary portion 50, the winding thread 32 is wound around it in that state, and then the fixing resin is applied over it to fix it in place.

[0032] Furthermore, as shown in Figure 6, by forming a larger diameter step 3D on the base end side of the gently tapered surface 3a, and ensuring that the open end 11a' of the jointed pipe body 11 fits against this portion, it is possible to suppress the outflow of adhesive 20 onto the surface of the large-diameter solid rod 3, and to further reduce the diameter difference.

[0033] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above and can be modified in various ways. In the embodiment described above, the connecting tube 11 is bonded and fixed to the large-diameter solid rod 3, but it may also be configured to be bonded and fixed to the small-diameter solid rod 5. Furthermore, the connecting tube 11 described above can be applied to the joint portion between tubular rods, and to the joint portion between a tubular rod and a solid rod.

[0034] Furthermore, in the above-described configuration, when fixing the outer surface 3a of the large-diameter solid rod 3 to the inner surface 11a of the jointed pipe body, adhesive 20 was applied to the outer surface 3a side. However, it may also be applied to the inner surface 11a, or only to the inner surface 11a. In this case, when applying adhesive to the inner surface 11a of the jointed pipe body, it is preferable to apply it to the opening side of the application position P1, which is on the opening side, relative to the stopping position P of the end edge 3b of the large-diameter solid rod 3 with respect to the inner surface 11a. It is preferable that this application position P1 be 8 mm or more, preferably 10 mm or more, relative to the stopping position P.

[0035] Furthermore, if the gap width G1 between the inner surface 11a at the open end 11a' of the jointed pipe body 11 and the outer surface of the end of the solid rod is 0.05 to 0.25 mm, the bonding surface does not have to be a flat tapered surface. [Explanation of Symbols]
