Detailed Description of the Invention

[0001]

The present invention relates to a fishing rod, on the pole, especially through in interpolating the fishing line to a fishing rod within the body.

[0002]

2. Description of the Related Art In recent years, there has been used a so-called centering rod of a type in which a fishing rod main body is formed of a tubular body having a hollow portion, and a fishing line is passed through the hollow portion. This middle fishing rod has less entanglement of the fishing line with the guide and is excellent in operability of the fishing rod as compared with a normal fishing rod in which a guide for passing the fishing line is provided on the outside of the fishing rod body.

However, in the case of a hollow fishing rod, when the fishing line put in water is wound up, the fishing line brings water droplets to the hollow portion of the fishing rod body, and the water droplets adhere to the inner wall of the fishing rod body. When the fishing line is inserted into the fishing rod body while water droplets are attached to the inner wall surface of the fishing rod body, the resistance of the water droplets adhering to the inner wall surface prevents the fishing line from smoothly passing through the fishing rod body. There is a problem that the operability of is deteriorated.

In order to solve such a problem, a hollow rod having a resin layer containing fluororesin particles on the inner wall surface of a fishing rod main body, which is a tubular body, has been developed in the past (Japanese Patent Laid-Open No. Hei 5 (1993) -58)
268858). This centering rod improves the water repellency of the inner wall surface of the fishing rod body to prevent water droplets from adhering to the inner wall surface.

[0005]

However, in the hollow rod having the above-mentioned resin layer, the water repellency of the inner wall surface is improved, so that the attached water droplets are easily moved, but the water droplets are not completely removed. Instead, they will remain scattered on the inner wall. When the fishing line is inserted into the fishing rod body with the water droplets scattered on the inner wall as described above, the resistance due to the water droplets is not necessarily smaller than that when the resin layer is not provided. For this reason, with the hollow fishing rod having the resin layer, the fishing line cannot be smoothly inserted into the fishing rod main body.

[0006] The present invention has been made in view of the above, and aims to provide a fishing rod which can reduce the resistance applied to the fishing line in the fishing rod within the body, it is inserted smoothly fishing line to a fishing rod body To do.

[0007]

As a result of intensive studies, the inventors of the present invention, contrary to the conventional method of reducing the resistance of water droplets by imparting water-repelling property to the inner wall surface of the fishing rod body, It has been found that resistance to water drops is reduced by imparting hydrophilicity to the inner wall surface of the fishing rod body, and the present invention has been completed.

That is, the first invention of the present invention comprises a tubular body having a hollow portion into which a fishing line can be inserted, and a hydrophilic region formed on the inner wall surface of the tubular body. The surface provides a fishing rod characterized by a contact angle with water of 80 ° or less.

A second aspect of the present invention provides a fishing line including a fishing line main body and a hydrophilic region formed on the fishing line main body. Here, in the first and second aspects of the present invention, the hydrophilic property means a property in which water spreads in a thin film when wetted with water. Specifically, the hydrophilic surface means a surface having a contact angle θ with water of 80 ° or less, preferably 60 ° or less.

In the first and second aspects of the present invention,
The hydrophilic region may form a hydrophilic layer on the inner wall surface of the tubular body or the fishing line body, or may be subjected to a treatment for imparting hydrophilicity to the inner wall surface of the tubular body or the fishing line body. That is, the hydrophilic region can be formed by forming a thin metal layer on the inner wall surface of the tubular body or the fishing line body by a wet or dry plating method, and oxidizing the surface to form a metal oxide layer. For example, it can be formed by forming an aluminum layer on the inner wall surface of the tubular body or the fishing line body, and subjecting this aluminum layer to an alumite treatment. Alternatively, the hydrophilic region can be formed by roughening the inner wall surface of the tubular body or the fishing line body to increase the surface area. As a method of roughening,
For example, a sandblasting treatment, a barrel polishing treatment, a honing treatment, a corona discharge treatment, a plasma treatment, and a physical treatment such as a spark treatment, or a chemical treatment such as a treatment using an acid or an alkali can be mentioned. Further, it can be formed by subjecting the inner wall surface of the tubular body or the fishing line body to a treatment with a surfactant. Alternatively, a hydrophilic layer may be formed and the surface of the layer may be further treated to impart hydrophilicity to form a hydrophilic region.

The thickness of the hydrophilic region of the tubular body in the fishing rod according to the first invention is preferably as thick as possible in consideration of abrasion resistance, but is preferably 10 to several hundreds of μm.
If the thickness of the hydrophilic region of the tubular body is less than 10 μm, a sufficient hydrophilic effect will not be exhibited. On the other hand, the thickness of the hydrophilic region in the fishing line according to the second invention is preferably 1 to several μm. This is because the hydrophilic area of the fishing line has a thickness of 1
If it is less than μm, the hydrophilic effect is not sufficiently exerted, and it is several tens μ
This is because the weight of the fishing line increases at the m level.

In the first invention, as the material of the tubular body, when the tubular body is used for a fishing rod main body, carbon fiber, glass fiber, aramid fiber, alumina fiber or the like reinforcing fiber is used as a thermosetting resin such as epoxy resin. A material obtained by mixing a matrix material of a thermoplastic resin such as or a polyether ether ketone resin or a polyether imide resin can be used. In addition, this tubular body heats the material
It is formed by pressurizing and curing. On the other hand, when the tubular body is used as the guide, synthetic resin, metal, or ceramics can be used.

The first aspect of the invention can be applied to a fishing rod whose tubular body is a fishing rod body, and can also be applied to a fishing rod which is a guide provided on the outside of the fishing rod body.

In the second invention, as the material of the fishing line main body, polyamide resin such as nylon, polyethylene resin, polyester resin or the like can be used. It goes without saying that by using the fishing rod according to the first invention and the fishing line according to the second invention, the fishing line can be more smoothly inserted into the fishing rod body.

[0015]

The fishing rod of the present invention is characterized by including a tubular body having a hollow portion into which a fishing line can be inserted, and a hydrophilic region formed on the inner wall surface of the tubular body. In the hydrophilic region of the inner wall surface of the tubular body, water droplets brought into the tubular body easily form a thin film. Therefore, the occupancy rate of water droplets inside the tubular body becomes small, that is, the cross-sectional area inside the tubular body that allows the fishing line to be inserted without contacting the water droplets becomes large. Therefore, when the fishing line passes near the center of the tubular body, water droplets are unlikely to adhere to the fishing line.

Further, when the fishing line passes while contacting the inner wall surface of the tubular body, the fishing line will pass through a thin water film, compared to the case where the fishing line passes through the inside of the tubular body where water droplets are scattered. Also reduces the resistance applied to the fishing line.

As a result, the fishing line can be smoothly inserted into the fishing rod body, and the operability of the fishing rod is improved.
The fishing line of the present invention is characterized by comprising a fishing line body and a hydrophilic region formed on the fishing line body.

In the hydrophilic region on the fishing line body, water droplets easily form a thin film. Therefore, similarly to the above, it is possible to increase the cross-sectional area inside the tubular body that can be inserted without coming into contact with water droplets. Further, even if the fishing line comes into contact with the inner wall surface of the tubular body, the resistance is reduced by the thin film of water on the surface of the fishing line. Further, when the fishing line is inserted into the tubular body of the fishing rod, the water droplets attached to the fishing line prevent the fishing line from attaching to the inner wall surface of the tubular body. As a result, the fishing line can be delivered and wound smoothly.

[0019]

Embodiments of the present invention will be specifically described below with reference to the drawings. (Embodiment) FIG. 1 is a front view showing an embodiment (middle fishing rod) of the present invention. In the figure, 10 indicates a tip rod. A top guide 11 is attached to one (small diameter side) of the tip rod 10. The small diameter side of the middle rod 12 is attached to the other (large diameter side) of the tip rod 10, and the small diameter side of the original rod 13 is attached to the large diameter side of the middle rod 12.

A fishing line introduction guide 14 is provided on the base rod 13. In addition, the fishing line introduction guide 14 of the base rod 13
A reel fixing device 15 is attached on the larger diameter side, and a reel 17 around which a fishing line 16 is wound is fixed to the reel fixing device 15. Further, a rod end component 18 is attached to the rear end of the original rod 13.

In the hollow fishing rod having such a structure, the fishing line 16 wound around the reel 17 is used as the fishing line introduction guide 1.
4 is inserted into the rod and is exposed from the top guide 11.

FIG. 2 is an enlarged sectional view of the portion A of the tip rod 10 shown in FIG. Reference numeral 20 in the figure denotes a tubular body that is the main body of the tip rod. A hydrophilic layer 21, which is a hydrophilic region, is formed on the inner wall surface of the tubular body 20. The hydrophilic layer 21 is formed by forming an aluminum layer on the inner wall surface of the tubular body and subjecting the aluminum layer to an alumite treatment.
The configuration shown in FIG. 2 is not limited to the tip rod 10 but the middle rod 12
Also, it is common in the area on the smaller diameter side of the fishing line introduction guide 14 in the base rod 13.

In the hollow rod having such a structure, in the hydrophilic layer on the inner wall surface of the tubular body, water droplets brought into the tubular body by the fishing line easily form a thin film. For this reason, the cross-sectional area inside the tubular body in which the fishing line can be inserted without coming into contact with water droplets becomes large. Therefore, when the fishing line passes near the center of the tubular body, water droplets are less likely to adhere to the fishing line, and when the fishing line passes while contacting the inner wall surface of the tubular body, the fishing line has low resistance (viscosity of water). (Resistance only)
It will pass through a thin water film.

When the fishing line passes through a thin water film, the resistance applied to the fishing line is smaller than when the fishing line passes through scattered water drops. This is the interface between air and water (3 in Fig. 3).
It is considered that this is due to the number of times that 3) is passed. The fishing line experiences resistance as it passes through the air-water interface. When water droplets are scattered, the number of times the fishing line passes through the interface between air and water increases, and as a result, the resistance that the fishing line receives is large. On the other hand, when the fishing line passes through a thin water film, the number of times the fishing line passes through the interface between the air and water of the fishing line decreases,
As a result, the resistance that the fishing line receives is small.

As a result, the fishing line can be smoothly inserted into the fishing rod, and the operability of the fishing rod is improved. (Comparative Example) For comparison, a hollow rod having the same configuration as that of the example was prepared except that the hydrophilic layer was not formed on the inner wall surfaces of the tubular bodies of the tip rod, the middle rod, and the main rod. In this hollow fishing rod, as shown in FIG. 3, the water droplet 31a attached to the inner wall surface of the tubular body 30 and the water droplet 31b attached to the fishing line 32 are attracted by the surface tension. It is in a state of being adsorbed inside. Therefore, when the fishing line moves, it moves while pulling the water droplets, which increases the resistance received by the fishing line. As described above, since this fishing rod has a large resistance to the fishing line, the operability is poor.

Next, the relationship between the moving speed of the fishing line and the resistance of the fishing line was examined for the hollow fishing rods of Examples and Comparative Examples. The result is shown in FIG. The resistance of the yarn was measured with a tension meter. Moreover, the measured value in FIG. 4 is an average value of the results of five measurements.

As can be seen from FIG. 4, the hollow fishing rod (white triangle plot in the figure) of the example had a stable and small resistance of the fishing line without being influenced by the moving speed of the fishing line. On the other hand, the middle-pile rod (white circle plot in the figure) of the comparative example had a large yarn resistance. In particular, the resistance of the fishing line was high when the fishing line was wound up or when a light weight (apparatus) was dropped into water and the moving speed was slow.

As can be seen from FIG. 4, the resistance of the line tends to decrease as the moving speed of the fishing line increases in both the embodiment and the comparative example. This is because as the moving speed of the fishing line increases, the force that opposes the force that prevents the movement of the fishing line, such as the force that pulls the water droplet, increases,
It is considered that as a result, the resistance received by the fishing line is reduced.

In the above embodiment, the case where an untreated nylon fishing line having an outer diameter of 0.235 mm is used as the fishing line 16, but the surface of the fishing line body is chemically treated with an acid or an alkali. The fishing line can be smoothly inserted through the fishing rod by using the one that is roughened by the treatment to form the hydrophilic region.

Further, in the above embodiment, the hollow rod in which the tubular body is the fishing rod main body is described, but the effect of the present invention is also obtained when the tubular body is a long guide provided outside the fishing rod main body. Is demonstrated. In addition, the present invention is
As long as the fishing line is inserted into the tubular body, it can be applied to all.

[0031]

As described above, since the fishing rod of the present invention has the hydrophilic region on the inner wall surface of the tubular body having the hollow portion into which the fishing line can be inserted, the fishing line can be smoothly inserted into the fishing rod body. Is something that can be done. Moreover, since the fishing line of the present invention has the hydrophilic region on the fishing line body, the fishing line can be smoothly inserted into the fishing rod body.
