Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having an improved joint.

[0002]

2. Description of the Related Art Conventionally, a joint portion of a fishing rod made of a synthetic resin may be strongly fixed and cannot be detached while the joint portion of the joint portion made of a synthetic resin is increased during use. For example, Japanese Utility Model Publication No. 4-4526 proposes a fishing rod for improving the above drawbacks. In the proposed fishing rod, in the joint portion of the fishing rod, a large number of micro hollow spheres are interposed in the synthetic resin, the surface is provided with a spherical layer having a non-contact concave portion that does not contact the peripheral surface of the other side coupling portion,
This prevents the joints from sticking. The above structure is intended to prevent sticking by forming a non-contact portion, but a sphere mixed with a synthetic resin is crushed by the resin when strongly pressed against the joining surface, or the other side rod tube. In fact, the effect of preventing sticking is extremely low. Also, the diameter of the sphere can be increased, but in this case, the non-contact portion can be easily formed, but on the other hand, there are drawbacks that the joining length changes and the joint portion has a large variation. Also, if the joint length of the joint portion changes and becomes shorter, it may break or tear, and if the joint length becomes longer, the condition of the rod will change.

[0003]

The problem to be solved is that the spheres mixed in the synthetic resin are depressed into the resin or the joint surface of the rod pipe on the other side when strongly pressed against the joint surface. In practice, the sticking prevention effect is extremely low.

In view of the above-mentioned drawbacks, an object of the present invention is to provide a fishing rod having an excellent effect of preventing sticking of a splicing part, preventing breakage and change in tone due to a change in splicing length, and having a splicing part with small variations. It is to be.

[0005]

In order to achieve such an object, the present invention has a thin wall thickness on at least one joining surface of a joining portion formed by joining a large diameter rod pipe and a small diameter rod pipe. The gist is that a hard coating is applied.

By the means for solving the problem, the large diameter rod tube 1
The joint portion 1a of the inner periphery of the joint surface 1b of the joint surface 1b is covered with a thin hard film 4 on the rod tube material 3 and the joint portion of the small diameter rod tube 2
When 2a is joined, the joining surface 1b and the joining surface 2b are joined by tightly bonding the thin hard coating 4 and the coating layer 8 of the small diameter rod tube 2. No deformation occurs on the surface of the hard coating 4 at the time of joining, and the hardness is higher than that of the raw material 5 of the small diameter rod tube 2 and the coating layer 8. Therefore, even if they adhere to each other, they do not bite each other and therefore they do not stick to each other. When the large-diameter rod pipe 1 and the small-diameter rod pipe 2 are rotated in mutually opposite directions at the time of joining and detaching, the thin hard coating 4 has a high lubricity, and therefore can be easily detached. Even if the thin hard coating 4 adheres with high lubricity, it can be easily removed by turning it sideways.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. First Embodiment FIGS. 1 to 3 show a first embodiment, and FIG. 1 shows a joint portion of a large diameter rod pipe and a small diameter rod pipe. 2 is a partial sectional side view of a joint portion of a large diameter rod pipe, and FIG. 3 is a partially enlarged sectional side view of FIG.

In the fishing rod, the taper-shaped inner peripheral joint surface 1b of the joint portion 1a of the large-diameter rod pipe 1 is joined to the taper-shaped outer periphery of the joint portion 2a of the small-diameter rod pipe 2. The surface 2b is spliced and detached. A thin hard coating 4 is coated on the rod pipe material 3 on the joint surface 1b on the inner peripheral end side of the joint portion 1a of the large diameter rod pipe 1. The drawing shows a swing-out type fishing rod. The thin hard coating 4 is made of metal or ceramics.

The rod pipe materials 3 and 5 of the large-diameter rod pipe 1 and the small-diameter rod pipe 2, respectively, are cut into sheet-shaped rectangles, and prepreg sheets (not shown) are wound around a core metal (not shown) appropriately times. The outside is taped, placed in a heating furnace, and integrally formed by thermosetting according to a conventional method. The prepreg sheet is, for example, a woven cloth reinforced with high-strength fibers such as carbon fiber, glass fiber, aramid fiber, alumina fiber, Keplera fiber, and other organic fibers and inorganic fibers, and epoxy resin, phenol resin, polyester resin, and the like. Of a thermosetting synthetic resin.

On the rod pipe material 3 of the joining surface 1b on the inner peripheral end side of the joining portion 1a of the large diameter rod pipe 1, a thin metal material such as nickel, aluminum or chrome is applied on the rod pipe material 3. When the coating film 4 is coated, a coating layer 6 for preventing electrolytic corrosion is formed on the rod pipe material 3 on the inner joining surface 1b of the joining portion 1a of the large-diameter rod pipe 1 and the inside thereof. A thin hard coating 4 is formed on the surface by plating or the like to smooth the surface. The hardness of the thin hard coating 4 is higher than the hardness of the rod pipe material 5 of the joint portion 2a of the partner small-diameter rod pipe 2 to be joined or the coating layer 7 coated on the surface of the joint portion 2a. Is formed in. The thickness of the thin hard coating 4 is less than 20 μm, preferably 10 μm or less. By reducing the thickness, it is possible to reduce the variation in the joint length due to the dimensional change of the thickness. The lubricity of the thin hard coating 4 is determined by the joint part of the small diameter rod pipe 2 on the other side to be joined.
Lubricity is higher than the surface lubricity of the rod tube material 5 of 2a and the coating layer 7 of the joint 2a.

When the thin hard coating 4 is coated by nickel plating or the like, corrosion resistance of the rod tube material 3 can be prevented. When the thin hard coating 4 is coated by chromium plating or the like, the surface hardness and wear resistance can be improved. When the thin hard coating 4 is formed by plating or the like, it is possible to apply a thin film having a constant film thickness as compared with the conventional coating process for preventing the fixing of the joint portion.
Easy size control. Compared to attaching metal parts to prevent the joint from sticking, it is lighter and does not change the condition of the rod.

[0012] The thin pipe hard material 4 is coated on the rod pipe material 3 on the joint surface 1b on the inner peripheral end side of the joint portion 1a of the large diameter rod pipe 1 by electroplating, You may process by electroless plating, hot dipping, dry plating, etc. The dry plating treatment may be performed by vacuum vapor deposition, ion plating, sputtering, chemical vapor deposition or the like.

The small diameter rod pipe 2 is joined by covering the upper portion of the rod pipe material 3 of the joining surface 1b on the inner end of the joining portion 1a of the large diameter rod pipe 1 with a thin hard coating 4 When the portion 2a is joined, the joining surface 1b and the joining surface 2b are coated with a thin hard coating 4 and a coating layer 7 for the small diameter rod tube 2.
Are closely attached and spliced. The surface of the hard coating 4 is not deformed at the time of joining, and the hardness is the material 5 of the small diameter rod tube 2 and the coating layer 7.
Since the height is higher, the joints are closely adhered to each other so that they will not come off during use, and they do not stick to each other so that they do not stick. When the large-diameter rod pipe 1 and the small-diameter rod pipe 2 are rotated in mutually opposite directions at the time of joining and detaching, the thin hard coating 4 has a high lubricity, and therefore can be easily detached. Even if the thin hard coating 4 adheres with high lubricity, it can be easily removed by turning it sideways.

When the fishing rod is constructed as described above, the joint portion is formed.
A thin hard coating layer 4 on the rod material 3 of the joint surface 1b of 1a
Since the joint surface 1b of the large-diameter rod pipe 1 and the joint surface 2b of the small-diameter rod pipe 2 are prevented from biting each other, the fisherman mutually connects the rod pipes in the storage direction from the jointed state. It becomes easy to rotate and can prevent sticking, and since the thin hard coating 4 is coated on the rod tube material 3 of the joint surface 1b, the wall thickness can be reduced and the joint length can be changed. The variation can be prevented, and the fishing rod has a joint portion with excellent accuracy.

In the above description, a thin hard coating 4 is coated on the rod pipe material 3 on the joining surface 1b on the inner peripheral end side of the joining portion 1a of the large diameter rod pipe 1, but a small diameter hard coating 4 is applied. A thin hard coating may be formed on the rod pipe material 5 on the outer peripheral joint surface 2b of the joint portion 2a of the rod pipe 2 to smooth the surface, and at this time, the joint portion 1a and the joint portion. 2a

[0025]

Since the present invention has been configured as described above,
Since a thin hard coating is formed at the joint of at least one of the large diameter rod tube and the small diameter rod tube, the hard coating will eat the other rod tube material, coating layer and hard coating with the hardness and lubricity of each other. Since sticking due to sticking does not occur, it becomes easier to rotate the rod tubes relative to each other, and a thin hard coating is applied to the joining surface, so the wall thickness can be made thin and the joining length and tone can change, and variations in them can occur. It is possible to provide a fishing rod which has an excellent effect such that it can be prevented from becoming large, and the fishing rod has a joint portion with excellent accuracy.
