DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod for fishing.

[0002]

2. Description of the Related Art Generally, a fishing rod is formed by joining a predetermined number of tapered rod pipes each having a smaller diameter from a base end toward a tip end. Adjacent rod pipes have a frictional force between the inner peripheral joint formed at the inner peripheral part on the distal end side of the rod pipe and the outer peripheral joint formed at the proximal outer peripheral part of the rod pipe disposed ahead of the rod pipe. It is joined by fixing.

In this case, the adjacent rod pipes are fixed by frictional force while sliding relative to each other, but the outer peripheral joint formed on the outer peripheral side on the base end side of the rod pipe is further fixed. When fixed to and separated from the inner peripheral joint formed on the inner peripheral part on the distal end side of the rod tube on the base end side, the area near the outer peripheral joint is easily damaged. That is, as described above, since the rod pipe has a tapered shape having a smaller diameter toward the distal end side, the outer peripheral joint formed on the outer peripheral part on the base end side of the rod pipe, There is almost no difference in diameter between the adjacent areas, and since sand and dust are likely to adhere to the fishing rod, the area where the rod pipes adjacent to each other are most likely to be damaged when they are slid together. is there.

[0004]

When the rod tube is scratched as described above, corrosion and the like progress due to penetration of moisture into the rod tube, and as a result, cracks, cracks, peeling and the like are likely to occur. This is not preferred in terms of durability. Therefore, in order to prevent damage to the area near the outer peripheral joint formed on the outer peripheral portion on the base end side of the rod tube due to friction at the time of sliding when the adjacent rod tubes are fixed to or separated from each other, each rod tube has its own It is sufficient to form a protective layer on the outer layer, but forming such a protective layer over the entire outermost layer of the rod tube increases the weight of the entire fishing rod.

The present invention has been made by finding a problem that occurs in a region near an outer peripheral joint formed on an outer peripheral portion on the base end side of a rod pipe. To provide a fishing rod that is excellent in durability and does not increase in weight by preventing damage in the vicinity of the outer peripheral joint portion at the time of fixing / removing, preventing the occurrence of cracks, peeling, and the like. With the goal.

[0006]

In order to solve the above-mentioned problems, the present invention is configured by joining a predetermined number of tapered rod pipes each having a smaller diameter from a base end toward a distal end. The fishing rod is characterized in that a predetermined range of a protective layer is coated on a front part of an outer peripheral joint portion of the rod pipe, and a protective film thicker than a front part thereof is formed.

[0007] The front portion of the outer peripheral joint formed on the base end side of the rod tube constituting the fishing rod is coated with a protective layer to a certain extent to fix and separate adjacent rod tubes. At this time, the most rubbed and easily damaged portion is protected. Further, since this protective layer is formed only in a minimum necessary area for preventing damage, the whole fishing rod does not become heavy. The number of the rod pipes and the material constituting the rod pipes are not particularly limited.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The fishing rod is provided with a predetermined number of tapered rod pipes having a smaller diameter from the base end side toward the distal end side,
By swinging each rod tube toward the distal end side, a joint portion between the rod tubes is fixed, and a fishing rod having a fixed length is obtained. In addition, by moving each rod tube toward the base end side, the joined state of each rod tube is released, and each rod tube is housed in the base end side rod tube, and finally all the rod tubes are housed. Is housed in the largest diameter pipe.

FIG. 1 is a view showing a part of a fishing rod, and adjacent rod pipes 1, 2, 3,... Are shown. As described above, each rod pipe is formed in a tapered shape having a smaller diameter toward the distal end side. In the figure, the left is the swing direction and the right is the storage direction. When each rod pipe is pulled out, the outer peripheral joint parts 1b, 2b,... Formed on the outer peripheral part on the base end side thereof are respectively formed on the inner peripheral joint part 2a formed on the inner peripheral part on the distal end side of each rod pipe. , 3
a,... are fixed by frictional force.

As shown in the figure, the front portions of the outer peripheral joints 1b, 2b,... Of each rod pipe are coated with a predetermined range of protective layers 1c, 2c,. Is formed with a protective film. In this way, by coating the front part of the outer peripheral joint portion with the protective layer only to a certain extent, when fixing and detaching adjacent rod pipes, the most rubbed and easily damaged portion is protected. Further, since this protective layer is formed only in a minimum necessary area for preventing damage, the whole fishing rod does not become heavy. Further, by forming such a protective layer, a set of marks or the like can be easily provided.

Although the length of coating the protective layer also depends on the taper amount of each rod pipe, usually, if the coating is performed at about 5% to 50% with respect to the length of the rod pipe, the length of the rod pipe becomes smaller. Scratches at the time of fixing and detaching of the fishing rod are effectively prevented, and the fishing rod does not become heavy. As this protective layer, the outermost layer of each rod tube may be coated with, for example, urethane, epoxy, paint, resin, or the like by brushing, spraying, squeezing, or the like.

FIG. 2 is a cross-sectional structure showing one configuration of the rod pipe having the above-mentioned protective layer formed thereon, and shows only the rod pipe 2 and the rod pipe 3 shown in FIG. In this configuration example, the metal coating 5 is formed on the outer peripheral surface of the rod pipe main body 2.
The metal film is formed by, for example, physical vapor deposition of a metal such as aluminum or titanium by vacuum deposition, sputtering, ion plating or the like. As described above, urethane, epoxy, paint, and the like are provided on the surface of the metal coating 5 in a certain range in front of the outer peripheral joint 2b.
A protective layer 2c such as a resin is coated. As a result,
The protective layer 2c forms a protective film that is thicker than the metal coating 5 in front of the protective layer 2c.
Effectively prevent damage due to sliding when detached.

In this configuration, the metal coating may be formed directly on the surface of the rod tube 2 or may be formed via a base layer (not shown). In this case, as a material constituting the rod pipe, polyamide resin, glass fiber reinforced polyamide resin, ABS (acrylonitrile-butadiene-styrene) resin, glass fiber reinforced ABS resin,
Synthetic resin such as polycarbonate resin; fiber reinforced prepreg in which carbon fiber, glass fiber, alumina fiber, aramid fiber, etc. are impregnated with synthetic resin such as epoxy resin, phenol resin, polyester, etc .; aluminum alloy,
Metals such as magnesium alloys and titanium alloys; ceramics such as zirconium oxide, aluminum oxide, silicon carbide and silicon nitride can be used. Further, as the base layer, a coating layer, a printing layer, a resin layer, or the like can be used.

A transparent (semi-transparent) protective layer (not shown) may be formed on the metal film 5 so as to protect the metal film. In this case, the above-mentioned protective layer 2c is formed on such a transparent (translucent) protective layer.

Furthermore, if the surface of the base layer (or the rod 2) on which the metal coating 5 is provided is smoothed to some extent, the appearance can be made brilliant. In addition, light is irregularly reflected at the portion of the metal coating 5 and the glitter is suppressed, so that a calm and calm appearance can be obtained. To obtain such an appearance with reduced glitter,
What is necessary is just to roughen the surface of the underlayer or the rod tube so as to form irregularities. Specifically, when the interval between the irregularities is S and the height is R, each of the regions to be roughened The average value Sm and the average height Ry are calculated as follows: Ry> Sm and Ry ≦ 5μ
What is necessary is just to grind so that it may be roughened to m. In fact, R
y is set to about 0.3 μm to 3 μm, and Ry ≧ S
It is preferable to roughen the underlayer so as to be m × 3.
If the metal film 5 is formed thick in such a roughened state, a metallic color with reduced glitter can be developed, and if the metal film 5 is formed thin, the metal layer 5 can be transparent to the underlayer (rod tube). Because of this, various colors or textures with reduced glitter can be expressed.

Alternatively, a water-repellent layer may be formed on the outer surface of the fishing rod main body so as to repel water in order to prevent dirt and deterioration in characteristics due to water, or to repel seawater or oil floating in water. Alternatively, a water / oil repellent layer as described in detail below may be formed. Such a water-repellent layer / water-repellent / oil-repellent layer can be formed directly on the rod tube main body, via an underlayer, or on the above-mentioned metal coating.

Examples of the material for the water / oil repellent layer include a fluorine compound having a perfluoroalkyl group, for example, a perfluoroalkyl acrylate copolymer such as perfluoroalkyl ethyl acrylate. In forming the layer, a solvent such as acetone or a nonionic or anionic emulsifier may be added to these fluorine compounds in order to facilitate the layer formation. Also,
A crosslinking agent is appropriately added to the fluorine compound. further,
An additive such as a synthetic resin such as triisocyanate or epoxy resin, or abrasion-resistant fine particles such as metal or ceramic may be added to the fluorine-based compound. This fluorine compound,
It has a structure represented by the following general formula I.

In formula (I), part (A) is a functional group, part (B) is a feeling adjusting group, and part (C) is a reactive group. Since the water and oil repellency effects are affected by the compounding ratio of the functional groups, the chain length and compounding ratio of the feel adjusting group, the type and compounding ratio of the reactive groups, the selection of the emulsifier, and the zeta potential,
The water and oil repellency characteristics can be controlled by appropriately selecting these.

The thickness of the water / oil repellent layer is preferably several μm to several tens μm in consideration of water / oil repellency, durability, antifouling property and the like. Further, the water repellent / oil repellent layer may have a certain degree of hardness to improve the durability. In addition, water repellent
By making the oil-repellent layer transparent or translucent, the color of the base layer or the rod tube may be represented as an appearance. The water-repellent / oil-repellent layer may be formed over the entire rod tube or may be formed partially.

Further, the above-mentioned water-repellent / oil-repellent layer may be provided on the inner wall surface of the rod tube so as to form a protruding portion by partially changing the thickness. By forming the projecting portion by the water-repellent / oil-repellent layer in this manner, the rod tube at the tip end penetrating the inside of the rod tube comes into contact with the projecting portion of the water-repellent / oil-repellent layer.
The area other than the projecting portion of the oil-repellent layer can be protected from contact with the insert. Thereby, the durability is improved, and the characteristics can be maintained for a long period of time.

The above-mentioned water / oil repellency means that when water or oil adheres in the air, the water or oil is repelled, and all the water or oil becomes beads and is removed, or a minute water droplet is removed. Or a property in which some oil droplets remain. Specifically, the surface having water / oil repellency means that the contact angle with water or oil, such as gasoline, is 110 ° or more in the case of water, 90 ° or more in the case of oil, preferably 150 ° or more in the case of water, 110 for oil
° or more, and the falling angle of water or oil (for example, the inclination angle necessary for a single water droplet or oil (for example, gasoline) droplet of 0.5 ml to fall on the inner wall surface of a rod) is water.
0 ° or less, 20 ° or less for oil, preferably 5 for water
° or less, and 10 ° or less in the case of oil.

In the member having the water / oil repellent layer having the above structure, the surface tension of the water / oil repellent layer (about 15 dyn / cm)
Is smaller than the surface tension of water or the surface tension of oil, the water or oil on the water / oil repellent layer is repelled in a bead shape. This can prevent not only water stains but also oil stains. By making the surface of the water-repellent / oil-repellent layer hydrophilic in water, the oil can float in the water even if the oil adheres to the water-repellent / oil-repellent layer. That is, the oil can be easily removed by washing.

FIG. 3 is a view showing the whole fishing rod in which a protective layer is formed by coating a protective layer in a predetermined area on the front part of the outer peripheral joint portion of the rod pipe. By forming a protective layer on each rod tube, the most rubbed and easily damaged portion is effectively protected when the rod tube is swung / stored. Further, since this protective layer is formed only in a minimum necessary area for preventing damage, the whole fishing rod does not become heavy.

As described above, the appearance of the fishing rod can be varied depending on the shape of the underlayer, the material, the formation of the metal layer, and the like. In this case, it is preferable that the lightness of the rod pipes 1 and 2 serving as the tip of the fishing rod be higher than the rod pipes 3 and 4 serving as the intermediate part and the rod pipes 5 and 6 serving as the base part. Usually, the tip of the rod is far away from the angler, and because of its small diameter, it blends into the surrounding landscape and becomes difficult to see,
As described above, by increasing the brightness, it is possible to easily see the tip of the rod, and the overall appearance and movement of the rod can be easily understood as a whole due to the glittering appearance and the high brightness.
