1 shows a side-by-side fishing rod according to an embodiment of the present invention. In FIG. 1, the fishing rod is a tip rod material 1.
0, an intermediate rod material 11, and a hand-held rod material 12 are configured. The rod members 10 to 12 are connected by male and female fitting. That is, the male fitting portions 15, 1 are provided at the rear ends (right end in FIG. 1) of the tip rod material 10 and the intermediate rod material 11.
6 are provided. Further, female fitting portions 17, 1 are provided at the front ends (the left end in FIG. 1) of the intermediate rod material 11 and the hand-held rod material 12.
8 are provided respectively. The hand rod material 12 is provided with a grip portion 13 and a reel seat base 14.

As shown in FIG. 2, the rod members 10 to 12 are
The rod material 20 is obtained by molding a resin containing high-strength fibers such as glass fiber and carbon fiber into a tubular shape, and a coating film 21 formed on the surface of the rod material 20. Male fitting 15,
Further, on the surface of 16, a urethane resin coating containing fine particles having elasticity (for example, trade name "Cenosoft II" manufactured by Cashew Co., Ltd., trade name "Velvex" manufactured by Fujikura Kasei Co., Ltd., Towa "ANE" manufactured by Paint Co., Ltd.
XTEL "or the like) is formed on the fitting layer 22. Further, in the female fitting portions 17 and 18, a resin layer 23 formed by impregnating a non-woven fabric with an epoxy resin is formed on the inner peripheral surface of the rod material 20. The resin layer 23 is finished to a predetermined accuracy by pressure-firing a non-woven fabric impregnated with an epoxy resin and finally reaming.

The coating film 21 comprises a base clear layer 30 formed on the outer peripheral surface of the rod material 20, a color layer 31 for developing a desired color, and a finish clear layer 32. The base clear layer 30 is formed by, for example, ironing a transparent base paint on the surface of the rod material 20. The color layer 31 is formed by applying a NY urethane resin coating material having a desired color on the base clear layer 30 with a black coat. The finish clear layer 32 is formed by spraying NY clear paint on the color layer 31. The fitting layer 22 is formed by spraying, for example, Cenosoft II.

Next, a method of manufacturing a fishing rod will be described. First, a mandrel is wrapped with a non-woven fabric impregnated with an epoxy resin to be the female fitting portions 17 and 18, and a prepreg made of, for example, carbon fibers impregnated with a resin is further wrapped in various directions. Then, the mandrel is pulled out after the pressure-fired by heating with the heat-shrinkable tape wound on this. In this way, the rod material 20 is obtained, and the rod material 2
The resin layer 23 of the female fitting portions 17 and 18 is simultaneously formed on the end portion of 0. After that, the resin layer 23 is reamed, for example, tapered to 2/1000.

Subsequently, the coating film 21 is formed. As described above, the coating film 21 is obtained by forming the base clear layer 30 by ironing, then forming the color layer 31 of a desired color by ironing, and further forming the finishing clear layer 32 by spraying. To be Finally, the male fitting part 1
The fitting layer 22 is formed by spraying the Senosoft II paint onto the portions to be 5, 16 by spray painting. The thickness of the fitting layer 22 is 5 to 25 μm, preferably 7 to 12 μm.
m is good. The taper toward the end of the fitting layer 22 is preferably about 2.3 / 1000. By forming a taper larger than that of the female fitting portions 17 and 18 on the male fitting portions 15 and 16 in this way, a so-called ball-end contact in which the two come into contact with each other near the entrance of the female fitting portions 17 and 18 is achieved. Etc. will not easily get inside the rod material.

The male fitting portions 15 and 1 thus obtained
Since the mating layer 22 is formed on the surface of 6, when the male mating portions 15 and 16 are fitted into the female mating portions 17 and 18, the contact with the resin layer 23 is flexible, and there is rattling or creaking. Is less likely to occur. Further, the change in friction coefficient when a flexible coating film was formed was measured. It has been found that the paint used for the male fitting part has a large difference in the pulling force against the pushing force and the variation in the pulling force itself. It was estimated that one of the causes was due to the difference between the static friction coefficient and the dynamic friction coefficient, and the static friction coefficient and the dynamic friction coefficient were measured in the examples and comparative examples by the following method.
That is, it is considered that when the rod members are connected, both rod members are in a dynamic friction state because they are moving, and when the rod members are removed, both rod members are in a static state, and therefore, it is considered that they are in a static friction state.
Therefore, it is presumed that the difference between the two friction coefficients causes the variation in the pulling force with respect to the pushing force.

[Measurement Method] Instead of the male fitting part, a flat OHP film was prepared by spraying the following paint uniformly. Senosoft II was applied as an example, NY clear paint was applied as Conventional Example 1, and matte paint was applied as Conventional Example 2. Further, instead of the female fitting portion, a non-woven fabric in which flat aluminum was impregnated with an epoxy resin was laminated, and after pressure baking, the surface was polished with ^# 180 sandpaper to prepare.

An aluminum plate, which is a substitute for the female fitting portion, is placed on the OHP film, which is a substitute for the male fitting portion, which has been spray-painted in this manner, and a weight of 2 kgf is placed on the aluminum plate, and the weight is placed. The one end of the yarn was fixed to and the other end of the yarn was pulled in parallel with a spring balance to measure the static friction coefficient and the dynamic friction coefficient. Two friction coefficients in the dry state and the wet state at that time are shown in Tables 1 and 2. FIG. 4 is a graph showing the results of Table 1 and Table 2.

[0018]

[Table 1]

[0019]

[Table 2]

As is clear from FIG. 4, when the SENOSOFT II used in the examples is applied, the static friction coefficient and the dynamic friction coefficient are almost the same. This does not change whether it is wet or dry. On the other hand, when the NY clear or the matte paint of the conventional example is applied, the static friction coefficient and the dynamic friction coefficient greatly change. From these, it can be seen that in the example, there is almost no difference between the coefficient of static friction and the coefficient of dynamic friction, so that the pushing force and the pulling force are substantially constant. The difference between the static friction coefficient and the dynamic friction coefficient is preferably 0.05 or less, and more preferably 0.02 or less.

As described above, since the fitting layer 22 having the numerical values of the dynamic friction coefficient and the static friction coefficient approximate to each other is provided, the pulling force is similar to the pushing force, and the constant pushing force is obtained. Variations in the withdrawal force are reduced, and sticking at the fitting connection portion is prevented. [Experimental Example] The same outer diameter is used in the embodiment in which the fitting layer 22 coated with Senosoft II is provided on the male fitting portions 15 and 16 and the conventional example in which the fitting layer coated with NY clear paint is provided. Two types were made and tested for pushing force and pulling force. The fishing rod used was a Shimano-made spatula fishing "Zhuchoho". At this time, the thickness of the fitting layer 22 is about 10 μm.
Also, the outer diameters of the male fitting portions 15 and 16 are 3.14 to 3.28 m.
m, the inner diameter of the female fitting portions 17 and 18 is 3.10 to 3.26 m
m.

Table 3 shows the test results for the pulling force with a pushing force of 3 kgf. Hereinafter, the numerical values of the test results show average values, and the minimum and maximum values are shown in parentheses.

[0023]

[Table 3]

Here, # 1 shows the numerical values when the tip rod material and the intermediate rod material are fitted, and # 2 shows the numerical values when the intermediate rod material and the hand-held rod material are fitted. Here, the pushing force is 3 kgf
In the case of, in the embodiment, the pulling force is 3.3 to 3.5 kgf,
Although the difference between the pushing force and the pulling force is not so large, the pulling force is 4.1 to 4.2 kgf in the conventional example.
Therefore, the pulling force is larger than the pushing force. Further, the variation of the pulling force is 3.3 to 3.
6 and the difference is as small as 0.3, whereas in the conventional example, the variation is 3.5 to 5.2 and the difference is 1.
There was also 7, and it was found that the variation in the pulling force was large.
Therefore, it can be seen that the fishing rod of the embodiment is a product that is easier to pull out and is less likely to stick to the product, as compared with the conventional product.

Next, how the pulling force changes in the dry state and the wet state when the pushing force is increased is compared between the embodiment and the conventional example. Here is the dry state,
4.0 kgf and 5.0 kfg in wet condition respectively
The pulling force was measured by the pushing force. Table 4 shows the measurement results.

[0026]

[Table 4]

The pulling force at 4 kgf in the embodiment is 4.2 to 4.3 in the dry state, and 4.1 to 1 in the wet state.
It was 4.4 kgf, and the difference between the pulling force and the pushing force was small and the variation in the pulling force was small regardless of the change in the state. The pulling force at 5 kgf is 5.2 to 5.7 in the dry state and 5.3 to 5.7 kg in the wet state.
However, the difference between the pulling force and the pushing force was small and the variation was small regardless of the change in the state.

On the other hand, the pulling force at 4 kgf of the conventional example is 5.4 to 5.6 in the dry state and 5.
It is 7 to 5.8 kgf. The pulling force at 5 kgf is 6.9 to 7.3 in the dry state and 7.2 to 7.6 kgf in the wet state. Therefore, the difference between the pulling force and the pushing force was large. In addition, as can be seen from the maximum and minimum values, the variation was large.

Subsequently, the female fitting portion is reamed to 2/10.
The change in the pulling force with respect to the pushing force due to the change in the taper of the male fitting portion when the taper of 00 was applied was measured. Here, in a wet state, two types of pushing force of 2 kgf and 3 kgf were measured. The taper of the male fitting part is 1.4 / 10.
00, 2.0 / 1000, 2.3 / 1000, 2.8 /
Four kinds of 1000 were prepared. Table 5 shows the measurement results.

[0030]

[Table 5]

As a result, the taper is 2/1000 to 2.
It was found that when it was 3/1000, the change between the pushing force and the pulling force was small. Next, the change in the pulling force when the tip of the tip rod material was repeatedly loaded was measured. The pushing force was 4 kgf, and the loads of 300 g and 600 g were each repeated 1000 times to be applied to the tip rod material. Table 6 shows the measurement results. In addition, here, the average value when there is no repeated load shown in Table 4 is shown in the parentheses.

[0032]

[Table 6]

As a result, in the embodiment, the change of the pulling force is 4.0 to 4.3 kgf for the load of 300 times, and the change of the pulling force is 3.8 to 4.3 kgf for the load of 600 times. The power did not change much. On the other hand, in the conventional example, 300
The change in the withdrawal force with respect to the load of 5.3 times 5.6 to 5.6, 60
The change in the pulling force was 5.0 to 5.5 with respect to the load of 0 times. As described above, it was found that the pulling force did not change much in both the example and the conventional example regardless of the presence or absence of the repeated load.

Next, the change in the pulling force when the rod material was repeatedly inserted and removed was measured. The pushing force is 3 kgf and the number of repetitions is 600 times. Table 7 shows the measurement results
Shown in

[0035]

[Table 7]

In the embodiment, the pulling force changes about 3.4 to 3.5 kgf after the repeated pulling and pulling operations 600 times, and it is found that the pulling force does not change much even if the pulling and pulling operations are repeated. . On the other hand, in the conventional example, 600
4.2-4.3kg for repeated insertion / removal operations
The pulling force changed by about f. As a result, it was found that at this time, there was no great change in the pulling force, but in the conventional example, the variation in the pulling force was large.

The present invention can be applied to a swing-out type fishing rod instead of the parallel type fishing rod. Further, although the rod with a guide is illustrated in the embodiment, the present invention can be applied to a fishing rod for spatula fishing without a guide.

[0038]

In the fishing rod according to the first aspect of the invention, since the fitting layer having flexibility is formed in the male fitting portion of the fitting connecting portion, there is no backlash or stain. Further, since the dynamic friction coefficient and the static friction coefficient of the fitting layer are close to each other, the pushing force and the pulling force are close to each other, and the variation of the pulling force is small with respect to a constant pushing force. For this reason, it becomes difficult to pull out and sticking is reduced, and the removal operation becomes easy.

In the fishing rod according to the second aspect of the invention, since the fitting layer is formed by applying the urethane resin paint containing the fine particles having elasticity, the fitting layer can be easily formed. In the fishing rod according to the third aspect of the present invention, since the static friction coefficient and the dynamic friction coefficient are substantially the same, the pushing force and the pulling force are more similar to each other, and the variation in the pulling force is smaller for a given pushing force. For this reason, it becomes difficult to pull out and sticks less, and the pulling operation becomes easier.
