Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hollow fishing rod having a water-repellent surface on the inner circumference.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, there has been known a mid-through fishing rod in which a water-repellent coating such as a fluororesin is formed on the inner circumference of a rod pipe to prevent the fishing line inserted inside the rod pipe from getting wet and to reduce the fishing line resistance.

[0003]

[Problems to be solved by the device]

 However, the surface coated with a water-repellent material such as fluororesin is easily scratched by the fishing line coming in and out, grooves are easily formed, and the durability is poor, and the fishing line is also easily scratched and broken. Is likely to occur. In particular, if dirt or salt attached to the fishing line adheres to the scratched water-repellent surface, there is a drawback that the fishing line cannot be smoothly delivered even after only one day of fishing.

[0004] Accordingly, it is an object of the present invention to provide a hollow fishing rod which can secure the water repellency of the inner circumference of the rod tube for a long period of time and can smoothly take in and out the fishing line.

[0005]

[Means for Solving the Problems]

 In view of the above object, the present invention forms a thin and thick layer having a water-repellent surface on the inner peripheral surface of a rod tube body layer formed by winding a prepreg in which high-strength fiber is impregnated or mixed with resin. Provided is a hollow fishing rod characterized in that an annular fishing line guide having abrasion resistance is arranged in a protruding manner from the water repellent surface of the thin and thick layer.

Further, a thin wall layer having a water-repellent surface is formed on the inner peripheral surface of a rod tube main body layer formed by winding a prepreg in which high strength fibers are impregnated or mixed with a resin, and the thin wall thickness is reduced. Provided is a hollow fishing rod characterized in that the surface of the layer is formed in a mixed state of a high-strength member having abrasion resistance and a water-repellent portion.

Further, a thin wall layer having a water-repellent surface is formed on the inner peripheral surface of the rod tube body layer formed by winding a prepreg in which high-strength fibers are impregnated or mixed with a resin, and A fishing line to be inserted inside is provided with water repellency on the surface of the fishing line, and a net thread which is softer than the water repellent surface of the thin and thick layer is used to provide a hollow fishing rod.

[0008]

[Action]

 According to the first invention, the wear-resistant annular fishing line guide is arranged so as to protrude from the water-repellent surface of the thin and thick layer, so that the fishing line that is strongly pulled when the fishing line is inserted has abrasion resistance. It is possible to prevent contact with a ring-shaped fishing line guide with a direct contact with a soft water-repellent surface. Therefore, the water-repellent surface lasts longer and the fishing line can be smoothly taken in and out.

According to the second invention, since the surface of the thin and thick layer is formed in a mixed state of the wear-resistant high-strength member and the water-repellent portion, the contact of the fishing line is wear-resistant. It is received by the high-strength member, and the water-repellent part does not easily wear. Even if it is worn out depending on the frequency of use, the water-repellent portion is recessed from the high-strength member to form a small uneven shape, and the water-repellent material is lost or the water repellency is reduced. Therefore, if the uneven surface is filled with wax or the like as a repairing work, the water-repellent surface is restored.

According to the third invention, since a thin and thick layer having water repellency is formed on the inner circumference of the rod tube main body layer, and the fishing line surface is also given water repellency, water droplets penetrate into the rod tube. In addition, it is difficult to use, and since the net yarn that is softer than the water repellent surface of the thin thick layer is used, it is possible to prevent the thin thick layer having water repellency from being scratched by the fishing line. Therefore, the water-repellent surface lasts longer and the fishing line can be smoothly taken in and out.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows a first embodiment according to the present invention. High strength fiber such as carbon is impregnated with thermosetting resin such as epoxy resin, or fiber reinforced prepreg (used in a broad sense including thermoplastic resin) in which thermoplastic resin such as polyamide is mixed is rolled and fired. A thin and thick layer 12 having a smaller thickness than that of the rod pipe main body layer 10 is formed on the inner periphery of the rod pipe main body layer 10 formed by molding, and the inner peripheral surface 12S has water repellency.

The thin and thick layer 12 may be formed only by a water-repellent material such as a fluororesin, a silicone resin, a Teflon resin, or a wax, and an epoxy resin may be used to form a fluorine fine particle having a size of 10 μm or less. It can be formed by mixing a water repellent material such as or silicon fine particles, or by coating a water repellent material on the surface of the film that improves the adhesion to the inner peripheral surface of the rod tube body layer 10. Its thickness is less than 500 microns, preferably 20-200 microns.

A wear-resistant annular fishing line guide 14 is arranged in a protruding manner from the water-repellent surface 12S at appropriate intervals in the longitudinal direction of the thin and thick layer 12. As a result, it is possible to prevent the surface 12S of the thin and thick layer 12 from being worn and damaged by the fishing line when the fishing line is inserted into and taken out from the inside, and the water repellency can be maintained for a long period of time. The fishing line guide 14 can be formed of ceramics or metal having a mirror-like surface or a composite material, or by depositing ceramics or metal on the surface of another material. Therefore, the fishing line resistance can also be reduced.

Further, the cross section thereof may be circular or flat. Further, when the use direction (upper and lower) of the fishing rod is fixed, the fishing line guide 14 may not be a perfect circular ring, but may be a semicircular ring only on the lower side.

In such an embodiment, as described above, the water-repellent surface 12S can be retained for a long period of time, but it gradually wears. In this case, even if wax or the like is applied to the inner circumference of the rod pipe for repairing the rod pipe, the intervals between the fishing line guides 14 are wide, so that the wax or the like is generally removed early.

Therefore, a second embodiment of the present invention shown in FIG. 2 will be shown in consideration of repairs and the like. This forms a thin-walled layer 12 'having a water-repellent surface S1 on the inner circumference of the rod body layer 10, and the surface of the thin-walled layer 12' serves as a wear-resistant high-strength member 16. It is formed in a mixed state with the water repellent part. As the high-strength member 16 having wear resistance, the same material as that of the guide member 14 may be used, or spherical ceramic particles may be solidified and formed. High strength fibers may also be used. In the latter case, a high-strength fiber knitted into a woven fabric or bag net is used. Further, a portion of the thin thick layer 12 'excluding the high-strength member 16 can be formed of the same material as that of the thin thick layer 12.

As described above, the surface S1 of the thin and thick layer 12 'is in a mixed state of the wear-resistant high-strength member 16 and the water-repellent portion, so that the fishing line is inserted in the inside thereof. Even when running, the high-strength member 16 protects the water-repellent part from abrasion. However, with long-term use, it gradually wears and becomes a minute concave surface S2 as shown in FIG. When the water-repellent effect disappears or decreases in this way, wax or the like can be filled.

Since the wax and the like thus filled are filled on the surface of the minute unevenness, unlike the case of the first embodiment, the wax is easily retained. Therefore, after the abrasion, the fishing line can be smoothly projected again and the water repellency can be maintained. In this way, the water repellent layer on the inner circumference of the rod can be repeatedly repaired.

The annular fishing line guide indicated by the chain double-dashed line 14 'is not essential in this embodiment, but if the fishing line guides are arranged at appropriate intervals in the longitudinal direction of the rod pipe, they can be repelled as in the case of the first embodiment. The wear of the water-based part can be further reduced. In the case of this example or the first embodiment, if the thin and thick layers 12 and 12 'are formed of elastic members or soft members with respect to the rod tube main body layer 10, the guide members 14 and 14' are attached. However, the buffering action can prevent damage. Further, in both the first embodiment and the second embodiment, there is almost no influence on the bending characteristics of the rod tube.

In addition to the above, in addition to the rod pipes of the first and second embodiments, a rod pipe in which only a thin and thick layer having a water-repellent surface is formed on the inner circumference of the rod pipe body layer 10. However, if the fishing line that is inserted inside the rod tube is given water repellency on the surface, and if it is made of polyethylene fiber mesh yarn, it is softer than the water repellent surface of the thin and thick layer on the inner circumference of the rod tube. Is. That is, since the net yarn has a soft surface that is easily bent and deformed, the water repellent surface on the inner circumference of the rod tube is not easily worn or damaged. In addition, since the surface of the rod is treated to be water repellent, it is difficult for water droplets to adhere to the surface, and it is difficult for water droplets to penetrate inside the rod tube. Furthermore, even if it enters, the water droplets can be easily removed during the operation of taking in and out the fishing line in cooperation with the water repellent surface on the inner circumference of the rod tube.

Further, since it is a polyethylene fiber mesh body, it is not easily melted by heat generated by frictional resistance with the rod tube, and is not easily scratched. In addition, it is difficult to be charged and dust is prevented from adhering.

A method for manufacturing the rod tube of the first embodiment will be described with reference to FIG. First, an elastic member such as a silicon tube or a receiving member layer 22 such as a clay-like member is interposed on the mandrel 20, and an annular guide ring 14 having a size for tightening the receiving member layer 22 is inserted outside the receiving member layer 22 (a). . Next, for example, the film (b) having a large number of small holes H arranged around the fluorine-based resin film SP is wound. A necessary number of windings of the fiber-reinforced prepreg 10P (c) are wound on the roll. After that, a fastening tape or the like is wound and heated and baked under pressure, the fastening tape and the mandrel 20 are removed after cooling, and the receiving member layer 22 is removed from the inside.

In this way, the fluororesin film SP becomes the thin and thick layer 12, the fiber reinforced prepreg 10P becomes the rod pipe main body layer 10, and the formed rod pipe has the annular fishing line guide 14 protruding to the inner periphery and the fiber The resin of the reinforced prepreg 10P flows into the small holes H of the film and promotes the integration of the thin and thick layer 12 and the rod tube body layer 10. The film SP may be in the form of a sheet or a tape. Further, the step of forming the film of (b) may be omitted, and after the annular fishing line guide 14 is integrated with the rod pipe main body layer 10, the inner periphery of the rod pipe may be coated with a water-repellent resin.

The manufacturing method of the rod tube of the second embodiment is basically the same as the above-mentioned method, but the thin-walled thick layer 12 ′ is preceded by a woven cloth body or a bag net body of high-strength fiber having abrasion resistance. When the sheet or tape of the water-repellent member is wound around it, the high-strength member and the water-repellent portion are mixed on the inner peripheral surface of the rod tube.

[Effect of device]

 As is clear from the above description, according to the first aspect of the invention, since the fishing line is guided by the wear-resistant annular fishing line guide, the fishing line does not come into strong contact with the water-repellent surface, and the scratches due to wear It is possible to prevent grooves and grooves, to ensure the water repellency of the inner circumference of the rod pipe for a long period of time, and to smoothly take in and out fishing lines. According to the second aspect of the present invention, since the surface of the thin and thick layer is formed by mixing the high-strength member and the water-repellent portion, the water-repellent surface can be held for a long time, and the fishing line can be smoothly taken in and out. You can also In addition, even if it wears out, it will be in a minute irregularity state, so the state of repair and filling with wax will last longer.

According to the third aspect of the present invention, since water repellency is imparted to the fishing line, it is difficult for water droplets to enter the rod tube, and the fishing line can be smoothly taken in and out. Further, since the fishing line is a net thread, it is soft, the water repellent surface on the inner circumference of the rod tube is not easily scratched, it can be held for a long time, and the fishing line can be smoothly taken in and out.
