Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod and a method for manufacturing the fishing rod, and more particularly to a technique for improving the slidability of a fishing line insertion space inside a rod material.

[0002]

2. Description of the Related Art Conventionally, there is a threading rod constructed as described above as disclosed in Japanese Patent Laid-Open No. 1-304836. In this conventional example, a thread guide member formed in a spiral shape is used. By arranging the fishing line on the inner surface of the rod material, the fishing line is prevented from adhering to the inner surface of the rod material and the fishing line is guided lightly.

Here, considering a threading rod, in this type of rod, as compared with a rod having a guide for guiding the yarn on the outer surface of the rod material, the yarn entanglement in the guide is prevented. It has a good surface that it is solved to make the rod operation easier, and in the above-mentioned conventional example, even when the wet fishing line is inserted through the inside of the rod material, the adhesion of the fishing line to the inner surface of the rod material It has a good aspect of preventing the above-mentioned problem and smoothly feeding the fishing line.

However, in the conventional example, since the thread guiding member manufactured separately from the rod material is inserted into the rod material, not only is it troublesome to manufacture the thread guiding member, but also the thread guiding member is used for the rod material. There is room for improvement because it takes time and effort to insert it into the inner surface of the.

For the purpose of eliminating this inconvenience, a fluororesin such as a polymer of ethylene trifluoride chloride and a polymer of tetrafluoride ethylene having good water repellency and a low friction coefficient is applied by means such as coating. It may be possible to form it on the inner surface of the rod material, but this type of resin was not very good in adhesiveness to other resins and was not feasible.

An object of the present invention is to construct a fishing rod that smoothly guides the fishing line without impairing the conventional good surface of preventing the fishing line from adhering to the inner surface of the fishing rod material. The reason for this is that a method for easily producing is reasonably constituted.

The mixture of the fluorine resin particles and the resin coating material is applied to the inner surface of the rod material and dried to form a resin layer containing resin particles on the inner surface of the rod material. It is that the manufacturing method is configured,

A third feature of the present invention is a centering rod in which a fishing line is inserted into the internal space of a rod material formed into a tubular shape, wherein a resin layer of ultra high molecular weight polyethylene is formed on the inner surface of the rod material. It consists of

A fourth feature of the present invention is a method for manufacturing a hollow rod in which a fishing line is inserted into the inner space of a rod material formed into a tubular shape, in which a film of ultra high molecular weight polyethylene is wound around a core material. , A prepreg in which high-strength fibers are impregnated with a thermosetting resin is wound around the outer surface of an adhesive layer formed on the outer surface of the film, and the rod material is baked by firing, and a resin of ultra-high molecular weight polyethylene is formed on the inner surface. It is in the point that it is formed into a tubular shape having layers, and the respective actions and effects are as follows.

[0011]

The above-mentioned first and second characteristics are described in, for example, FIGS.
With the configuration as shown in Fig. 3, the rod material R is used when manufacturing the hollow rod.
A resin layer P is formed by applying a mixture of the fluorine resin particles 8 ... And the resin coating material 9 to the inner surface of the resin, and drying the resin layer P. The main component is a resin coating material 9 having good adhesiveness with the rod material, such as polyurethane, in place of the one having poor adhesiveness with the rod material R, such as a fluorine resin such as an ethylene polymer. Therefore, the resin layer P is formed in a state of being firmly adhered to the rod material R. Further, on the surface of the resin layer P thus formed, the fluororesin particles 8
Since the water is exposed, even if the fishing line 6 in a wet state may come into contact, the water repellency of the fluororesin particles 8 ... Is suppressed, and the resistance of the fishing line 6 during movement is reduced due to the low friction coefficient of the fluororesin particles 8.

The third and fourth characteristics described above are shown in FIG.
If configured as shown in FIG. 9 to FIG. 9, a film of the ultrahigh molecular weight polyethylene 12 on which the adhesive layer 14 is formed in advance is wound around the core material 13 at the time of manufacturing the hollow rod.
A sheet-like prepreg 15 is wound around the outer surface of the prepreg 15 and fired, and then the core material 13 is extracted, so that the resin layer Q of the ultra high molecular weight polyethylene 12 is attached to the inner surface of the prepreg 15 through the adhesive layer 14.
The rod material R provided with is formed. Further, in the resin layer Q thus formed, the ultrahigh molecular weight polyethylene 12 having high wear resistance and high lubricity is exposed on the wide inner surface, so that the wet fishing line 6 may come into contact with the resin layer Q. Even if there is, the good water repellency of the resin layer Q prevents the water from spreading in the form of independent droplets, and as a result, the fishing line 6
The adhesion of the fishing line 6 is suppressed, and the low friction coefficient of the resin layer Q reduces the resistance when the fishing line 6 moves.
The ultra high molecular weight polyethylene 12 has a static friction coefficient of about 0.25 and a dynamic friction coefficient of about 0.15.

That is, in the present invention, the fluorine resin particles 8
.. Or, due to the property of the ultra high molecular weight polyethylene 12, while smoothly guiding the fishing line 6 as in the conventional case,
The resin layers P, Q having good properties by allowing the fishing line 6 to move with a light force, and by a relatively simple process of coating or by an improvement such that one process is added when the rod material R is manufactured. Is formed.

[0014]

As described above, the fishing rod can be smoothly and lightly guided without damaging the conventional good surface of preventing the fishing line from adhering to the inner surface of the fishing rod material, and the fishing rod can be easily carried out. The manufacturing method was reasonably constructed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 6, the rod material R of each of the tip rod 1, the intermediate rod 2, and the base rod 3 is configured in a parallel joint type, and the base rod 3
A fishing rod is mounted on which a fishing reel 5 is mounted via a reel seat 4. In this middle fishing rod, the fishing line 6 is inserted into each rod material R from the line insertion hole 7 formed in the middle portion of the original rod 3.
In order to send the fishing line 6 smoothly into the inner space of the rod material R, the inner surface of the rod material R is formed on the inner surface of the rod material R as shown in FIGS. 1 and 2. To
A resin layer P in which fluorine resin particles 8 made of a polymer of tetrafluoroethylene are mixed in a polyurethane resin coating material 9 is formed.

This fluororesin made of a polymer of ethylene tetrafluoride has the chemical formula of its monomer:

[0017]
