Abstract

PROBLEM TO BE SOLVED: To provide an interline fishing rod capable of decreasing the resistance of the line on the inner face of the rod, stabilizing the joint length at the joining part of the rods and preventing the slip of a small-diameter rod in the case of a gelescopic extension rod. SOLUTION: The interline fishing rod is produced by forming a line-guiding hollow part in a rod pipe obtained by winding a fiber-reinforced prepreg composed of a reinforcing fiber impregnated with a synthetic resin. The hollow part has a joining face on the inner circumference of the tip end part to join the outer circumference of the rear end of a rod pipe having a diameter smaller than the former rod pipe. A water-repelling film 30 is formed on the inner surface of the rod pipes excluding the joining part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod in which a rod tube is subjected to a water-repellent treatment.

[0002]

2. Description of the Related Art A through fishing rod is usually formed by winding a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin.
It is formed through steps such as curing and de-centering. It is also known that, in a through fishing rod formed through such a process, ridges are formed at predetermined intervals on the inner peripheral surface thereof in order to reduce the line resistance (Japanese Patent No. 28079).
No. 70 gazette).

[0003] In the method of forming a through fishing rod disclosed in this publication, a release agent is applied to the core so that the core and the tube material are easily released during the decentering step. The water repellent effect of the release material attached to the surface of the ridge body at the inner peripheral portion of the rod pipe is formed.

[0004]

According to the prior art disclosed in the above publication, the resistance of the fishing line passing through the inside of the rod can be reduced by the ridge and the water-repellent surface attached to the surface thereof. However, the water-repellent treatment is not performed between the ridges and the ridges where water droplets are likely to accumulate (the so-called rod pipe surface portion). , The effect quickly disappears.

[0005] A water-repellent film may be formed on the entire inner circumference of the rod pipe. However, a variation in the thickness of the film causes an unstable joint length at a joint between the rod pipes. And breakage easily occurs. Also, in the case of a swing-out type fishing rod, if a water-repellent film is formed at the joint, the dispersion and the surface resistance of the film are small, and the fishing rod drops during use of the fishing rod. (The phenomenon of falling into the rod pipe) is likely to occur.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. The present invention has been made to reduce the fishing line resistance inside a rod tube and stabilize a joint length at a joint portion between rod tubes. Another object of the present invention is to provide a through fishing rod in which a small diameter rod tube in use is prevented from dropping in the case of the swing type.

[0007]

In order to achieve the above object, the fishing rod according to the present invention is provided with a fishing line inside a rod tube formed by winding a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin. A hollow portion for guiding is formed, and a joining surface for joining a rear end outer periphery of a rod pipe smaller in diameter than the rod pipe to an inner periphery of a tip end of the rod pipe is provided. A water-repellent film is formed on the inner surface excluding the surface.

In the above configuration, the portion where the water-repellent film is not formed is only the joint portion when the large-diameter rod tube and the small-diameter rod tube are joined, or extends from such a joint portion to the base end side. The predetermined range is set. When a spiral ridge is provided on the inner peripheral surface of the rod pipe, the portion where the water-repellent film is not formed is in a range from the joint portion to a position where the first ridge on the base end side is located. Good to do.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a fishing rod according to an embodiment of the present invention will be described with reference to the accompanying drawings.
In addition, the through fishing rod of the present invention is configured by a joint type, a spigot type, a swing type, and the like, and FIG. 1 shows a fishing rod configured as a swing type as an example.

A through fishing rod 1 shown in FIG.
It is composed of a middle rod pipe 6 joined to the original rod pipe 2 via a joint 4 and a head rod pipe 10 joined to the middle rod pipe 6 via a joint 8. The rod pipe is made of a prepreg (F) in which reinforcing fibers are impregnated with a synthetic resin, as in the prior art.
RP). In addition, in FIG. 1, although the inside rod pipe is comprised only by one piece, the number of the inside rod pipes arrange | positioned between the former rod pipe 2 and the head rod pipe 10 is not limited. .

The original rod tube 2 has a reel leg fixing device 12 attached thereto.
Is attached, and the reel 12a is detachably attached thereto. After the fishing line 16 sent out from the reel 12 a attached to the reel leg fixing device 12 is introduced into the original rod tube 2 via the fishing line introduction guide 18 a in the fishing line introduction unit 18 provided in the original rod tube 2, Through the middle rod tube 6 and the head rod tube 10, the head rod tube 1
0 is sent out from the top guide 10a attached to the front end of the “0”. In this case, the fishing line introduction part 18 may be formed in a middle rod pipe.

FIG. 2 shows the middle rod pipe 6 (large-diameter rod pipe) shown in FIG.
2 shows a cross-sectional structure of a joint portion between the head and the tip rod pipe 10 (small diameter rod pipe).

As shown in this embodiment, each rod tube 6,
A spiral (or ring-shaped) fishing line support portion (protrusion) 20 protruding into a hollow portion through which the fishing line is inserted, so that the penetration of the fishing line is improved (friction resistance is reduced). Is preferably formed. In this case, the minimum inside diameter of the fishing line support part 20 formed in the large diameter rod pipe is formed larger than the rear end outer diameter of the small diameter rod pipe ahead of it, and the small diameter rod pipe is placed in the large diameter rod pipe. It can be stored or pulled out rearward. Further, the shape of the fishing line support portion 20 can be a mountain shape, a semicircular shape, a trapezoidal shape, or the like, and is not limited.

A guide ring 22 is preferably mounted on the inner periphery of the base end of the small diameter rod tube 10 in order to improve the penetration of fishing line. When such a guide ring 22 is fitted, it can be fixed or detachable by screwing.

In the above configuration, the inner peripheral surface of the rod tube (the surface between the ridges) and the surface of the fishing line support portion 20 are
A water-repellent layer 30 (hereinafter, referred to as a water-repellent layer or a water-repellent film) is formed. The material for forming the water-repellent layer is arbitrary, and for example, fluorine, silicon, or the like can be used. In addition, such a water-repellent layer 30 can be formed by spraying, spraying a coating solution, dipping (removing unnecessary portions or masking before the coating solution is injected or masking it before the injection), brush coating, etc. A film made of an aqueous material (a film with a water-repellent layer formed) can be wound around the outside of a metal core, an FRP prepreg can be wound thereon, and then heat-formed by a conventional method. It is. Alternatively, it can be formed using a plating method.

By forming the water-repellent layer on the surface of the ridge, the resistance of the fishing line passing through the hollow portion is reduced, and the fishing line can be guided smoothly. Further, by forming a water-repellent layer on the inner peripheral surface of the rod tube, a water-repellent effect can be maintained for a long period of time, and a configuration having excellent durability can be obtained.

The above-mentioned water-repellent layer 30 is formed of a large-diameter rod tube 6.
It is not formed on the inner peripheral surface of the large-diameter rod at the joint R1 between the small-diameter rod and the small-diameter rod. That is, by not forming the water-repellent layer in such a region, the joint length at the joint portion between the rod pipes due to the variation in the film thickness can be stabilized, and breakage can be effectively prevented. In the case of a fishing rod of the swing-out type as shown in the figure, by not forming a water-repellent layer at the joint portion, it is necessary to prevent the small-diameter rod tube from dropping due to the variation of the film and the low surface resistance. Can be.

In this case, the region where the water-repellent layer 30 is not formed as described above may be only the joint portion R1, but it is preferable that the region is not formed even in the predetermined region R2 on the base end side. (Therefore, the region where the water-repellent layer is not formed is R). In this case, it is preferable that the region R2 is set to such a degree that the straightly extended fishing line does not come into contact with the line when the fishing line is inserted, and more specifically, the region R2 is set to 1/3 or more and 3 times or less of the joint length R1. Actually, a length that is not formed may be set according to the inner diameter of the guide ring 22 attached to the rear end of the small-diameter rod pipe, and when the inner diameter of the guide ring 22 is relatively small,
As shown in the figure, it is preferable to set the range up to the position where the first ridge is present. It should be noted that a region where such a water-repellent layer is not formed may have a release agent for releasing the release from the core metal.

As described above, in the region R where the water-repellent layer 30 is not formed, it is preferable to form the reinforcing layer 35 so as to improve the strength of the joint. Such a reinforcing layer can be composed of a prepreg in which reinforcing fibers are aligned in the circumferential direction, or a prepreg in which the reinforcing fibers are aligned in the inclined direction. It may be arranged at a position or an outer layer position. In addition, the reinforcing fiber is formed so as to be exposed (partly) at the joint,
By forming it on a rough surface, a small diameter rod pipe can be reliably joined (fixed).

Next, the laminated structure including the water-repellent layer of the rod tube having the above-described structure will be specifically described.

FIG. 3 is a sectional view showing the structure of the inner peripheral surface of the above-described rod pipe (including the original rod pipe, the middle rod pipe, and the tip rod pipe shown in FIG. 1 and denoted by reference numeral 50). FIG.
As shown in the figure, the rod tube main body 50 has a three-layer structure of an inner layer 50a, an intermediate layer 50b, and an outer layer 50c. Inner layer 5
The outer layer 50a and the outer layer 50c are made of a carbon circumferential fiber layer, a glass scrim cloth layer (woven fabric layer) or a carbon axial fiber layer, or a combination thereof.
Is composed of a layer mainly composed of an axial fiber layer or an inclined fiber layer.

As described above, a plurality of ridges 20 are formed on the inner peripheral surface of the rod tube main body 50 at a predetermined pitch, and a water-repellent resin containing fine water-repellent particles is formed thereon. The water-repellent coating 30 made of is fixed. In addition,
The water-repellent coating 30 preferably has a complex uneven surface having not only “fine irregularities” but also “fine irregularities” having a smaller depth.

In this configuration, the term “fixing” refers to, for example, the formation of the water-repellent coating 30 by coating (liquid, powder, etc.), printing, winding a prepreg or a resin film, vapor deposition, plating, bonding, or the like. Means to do. Also,
"Water repellency" means that the contact angle of a water drop is at least 130 degrees or more, preferably 140 degrees or more, more preferably 1 degree or more.
It means between 50 degrees and 180 degrees.

It is preferable that the ridge 20 is made of a wear-resistant material. Usable wear-resistant materials include, for example, fiber reinforced resin using ceramic fiber, carbon fiber, glass fiber, etc., PET as reinforced fiber,
Aramid, PTFE, using organic fibers such as PE,
Alternatively, a synthetic resin film, a thread, a ceramic material (ring shape), or the like can be used. The height of these ridges 20 is 0.1 to 1 mm, preferably 0.2 to 1 mm.
It is preferable to set the range to 0.6 mm. Also,
The pitch of the plurality of ridges 20 is preferably set in the range of 2 to 30 mm, and more preferably 5 to 20 mm, and is formed in a spiral shape or a ring shape.

The water-repellent coating 30 is fixed over a region between the plurality of ridges 20, and the thickness thereof is set smaller than the height of each ridge 20. In this case, the thickness of the water-repellent coating 30 is 1 to 100 μm, preferably,
It is preferable to set the range of 3 to 20 μm.

As shown in FIG. 3, the top of the ridge is shaved off by abrasion with the fishing line, and the base of the ridge improves drainage when the fishing rod is tilted. Considering that a smooth shape is preferable, the water-repellent coating 30 is the thinnest at the top 20a of the ridge 20 and the base of the ridge 20 in order to form the coating effectively without waste. It is preferably formed so as to be thickest at 20b and to have an average thickness in a region 20c between the ridges 20.

The water-repellent coating 30 is formed using a water-repellent resin such as a fluororesin or a silicone resin into which water-repellent particles 46 such as fluororesin particles are dispersed and mixed as shown in FIG. In addition to painting, for example, when the prepreg sheet is wound to form the rod pipe main body 50, the water-repellent resin mixture is fixed to the prepreg sheet in advance, so that the rod pipe main body 50 is completed at the same time as the rod pipe main body 50 is completed. It is formed on the inner peripheral surface of the tube main body 50.

Note that the minute uneven surface of the water-repellent coating 30 is formed by combining a convex portion composed of an aggregate of a plurality of water-repellent particles bound by a binder and a concave portion formed between these convex portions. ing. In this case, the concept of “small” refers to such a small size that air that enters a concave portion having minute irregularities is retained in the concave portion and water droplets do not enter the concave portion. As a specific example, when the water-repellent coating 30 is viewed on a plane, the number of combinations of the concave portions and the convex portions is 100 or more or 1000 when converted per unit area (for example, 1 mm ² ). Above, preferably 5000 to 100
It means that 10,000 or more are formed. In other words, the concept of “micro” means that the difference in height between the concave portion and the convex portion is 10 μm or less, preferably 0.1 μm or less.
1 to 5 μm, and the pitch between the concave portion and the convex portion is set to 10 μm or less, preferably 0.1 to 5 μm.

The fine uneven surface of the water-repellent coating 30 is an uneven surface deeper than the particle size of the fine water-repellent particles.
The concept of "fine" in this case is such a fineness that air that enters the concave portion of the fine irregularities is retained in the concave portion and water droplets do not enter the concave portion. When the coating is viewed on a plane, the combined number of the concave portions and the convex portions is 10 or more or 100 or more, preferably 10 or more in terms of unit area (for example, 1 mm ² ).
It means that 500,000 or more are formed. In other words, the concept of “fine” means that the height difference between the concave portion and the convex portion is 10 μm or less, preferably 0.2 to 5 μm, and the difference between the concave portion and the convex portion. The pitch is 100 μm or less, preferably 0.2 to
It means that it is set to 5 μm.

If the water-repellent particles 46 are densely arranged on the side of the rod tube main body 50, the fastening (adhesion) area between the rod tube main body 50 and the water-repellent coating 30 becomes small, and as a result, Since the adhesion (adhesion) of the water-repellent film 30 to the main body 50 may be reduced, the water-repellent particles 46
It is preferable to concentrate on the surface side of 0 and its vicinity.

As described above, the water-repellent particles 46 are
By focusing on the surface side of 0 and its vicinity,
Since the boundary surface between the rod pipe main body 50 and the water repellent coating 30 can be in a state where the water repellent particles 46 are small or almost nonexistent, the fixing (adhesion) between the rod pipe main body 50 and the water repellent coating 30 is performed. ) The area can be increased. As a result, the adhesion (adhesion) of the water-repellent coating 30 to the rod pipe main body 50 is obtained.
Can be improved.

As described above, according to the present embodiment, the plurality of ridges 20 are formed at a predetermined pitch, and even in the region between the plurality of ridges 20, the minute uneven surface is formed. By providing the water-repellent coating 30 having the above, it is possible to provide a fishing rod capable of reducing the frictional resistance of the fishing line 16 and maintaining excellent water repellency for a long period of time. That is, even if seawater, water, or the like covers the fishing rod (in the present embodiment, the inner peripheral surface of the middle rod pipe 6 (the rod pipe main body 50)), water droplets and the like can be quickly removed by the minute uneven surface. Therefore, it is possible to prevent water droplets and the like from adhering to the water-repellent coating 30. That is, when a water droplet or the like adheres to the water repellent film 30, the water droplet or the like draws the fishing line 16 to the water repellent film 30, and the contact state between the fishing line 16 and the water repellent film 30 increases. However, due to the presence of the minute uneven surface, it is possible to prevent water droplets and the like from adhering to the water-repellent coating 30.
The contact of the fishing line 16 with the fishing line 16 can be reduced to reduce the line resistance, and the contact of the fishing line with a small amount can protect the water-repellent coating 30.

The configuration shown in FIG.
FIG. 4 is a cross-sectional view showing the water-repellent coating 30 formed on the inner peripheral surface of FIG. In the example shown in FIG. 4, the water-repellent coating 30 has a configuration that also contains abrasion-resistant particles 60 in addition to the water-repellent particles 46. In this case, as the wear-resistant particles 60, silica, alumina, glass, SiC, stainless steel, or the like can be used.

The wear-resistant particles 60 may have a particle diameter larger than the water-repellent particles 46 contained in the water-repellent coating 30 and smaller than the thickness of the water-repellent coating 30. The particle size of the water-repellent particles 46 is, for example, 0.1 μm.
m to 1 μm, and the particle size of the wear-resistant particles 60 is, for example, 0.2 μm to 5 μm.

Accordingly, the water-repellent coating 30 contains the water-repellent particles 46 having a small diameter and the wear-resistant particles 60 having a large diameter in a water-repellent resin as a binder. Provide a finished surface. That is, the relatively small water-repellent particles 46 form relatively smooth fine irregularities, and the large-diameter wear-resistant particles 6
A surface with protruding zeros is obtained.

In the water-repellent film 30 having the structure shown in FIG. 4, the ratio of the water-repellent resin to the total amount of the film is, for example, 6%.
It is preferred to be 0 or less than 50% by weight. By using the amount of the water-repellent resin in such a range, it is possible to easily form the unevenness of the surface of the water-repellent coating 30 deeply.

In the above embodiment, an example was described in which the water-repellent coating 30 was formed on the entire inner surface of the rod pipe on which the ridges 20 were formed.
Alternatively, the rod may be partially formed, or may be applied to only one rod pipe among the rod pipes constituting the fishing rod, or to all rod pipe sections. The present invention can also be applied to a through fishing rod that does not form a ridge on the inner peripheral surface of the rod pipe. The water-repellent film does not need to contain the above-described wear-resistant particles 60, and when it is contained, its shape can be appropriately modified.

[0038]

As described above, according to the through fishing rod of the present invention, the fishing line resistance inside the rod pipe can be reduced, and the joint length at the joint between the rod pipes can be stabilized. A decrease in strength can be prevented. Further, in the swing-type through fishing rod, it is possible to prevent the small diameter rod pipe from dropping during use.
