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

[0002]

2. Description of the Related Art Generally, fishing rods of this kind are disclosed in
As can be seen in Japanese Patent Publication No. 71, a hollow conical hollow rod having a fitting inner surface at the distal end and a fitting outer surface at the base end,
It also has a plurality of loose conical intermediate rods having a fitting inner surface at the distal end and freely reciprocating inside the former rod, and each of the intermediate rods when not in use, such as when carried to a fishing ground. The rods are housed in the original rods, and at the time of fishing, the respective intermediate rods are sequentially pulled out, and the base-side fitting outer surface is fitted to the distal-side fitting inner surface of the adjacent large-diameter side rod. They are configured so that they can be brought into contact with each other and fitted to each other so that they can be used at a fixed length.

In the meantime, the applicant of the present invention firstly fits the base fitting outer surface of at least the large-diameter intermediate rod of the intermediate rod with the rod bottom end of the original rod. A holding surface for holding the base end of the intermediate rod is provided, and the outer surface of the distal end of the intermediate rod held on the original rod is built up to form a buildup layer, and the outer surface of the buildup layer is formed. A fitting surface of a predetermined length for contacting the inner surface of the fitting end on the distal end side of the adjacent large-diameter rod and locking the movement in the longitudinal direction, so that at least the large-diameter intermediate rod is used for fishing. The rod is housed in the original rod, the base end thereof is held on the holding surface of the original rod, and the distal end fitting surface is brought into contact with the inner fitting surface of the adjacent large diameter side rod. A fishing rod that locks the stored large-diameter side intermediate rod in the longitudinal direction and prevents the tip of the intermediate rod from swinging radially with respect to the large-diameter side rod and rattling. The proposed (JitsuganAkira 63 over 12009
No. 8).

[0004]

However, as described above, the intermediate rod which is housed in the original rod and locked in the longitudinal direction as described above has its base end held on the holding surface of the original rod. And the longitudinal movement is locked, and the distal end is in contact with the inner surface of the distal end of the adjacent large-diameter rod to lock the movement in the longitudinal direction. Since the movement in the length direction is locked between the base end portion and the tip end portion of the rod, the stored intermediate rod is exposed outward to the distal end edge of the adjacent large diameter rod. It is difficult to pull out the tip part that has been pulled out.

On the other hand, in order to prevent the front end of the intermediate rod, which is housed in the original rod as described above and whose base end is held on the holding surface, from swaying in the radial direction, it is possible to prevent rattling. , The tip side fitting surface of the intermediate rod
It is necessary to machine the outer diameter to match the inner surface on the tip side of the large diameter rod in contact with the fitting surface, but each rod has a gentle conical shape inclined at a very gentle angle. Because it is formed into a predetermined length by cutting both ends of the formed rod, an error in the cutting position greatly affects the radial runout, The fitting surface of the intermediate rod, which is built up to provide the fitting surface, is formed to have a smaller diameter than the fitting inner surface of the large diameter rod in contact with the fitting surface. Since it is necessary to be able to pull out the mating surface portion more outward than the distal end edge of the large diameter rod, the fitting surface of the intermediate rod is brought into contact with the large diameter rod in contact with the fitting surface. It took a lot of time and effort to process the rod to the diameter that fits the inner surface of the rod. That is, the intermediate rod is inserted into the large-diameter rod until the mating surface of the intermediate rod formed by building up the inner surface of the large-diameter rod in contact with the mating surface. Since it is necessary to repeat the removal and the polishing of the fitting surface, the workability is poor and the cost is high.

An object of the present invention is to accommodate at least a large-diameter-side intermediate rod so that its movement in the length direction can be locked, and
While the radial deflection on the tip side can be suppressed, the retractable intermediate rod can be easily pulled out, and
The present invention is to simplify the radial deflection on the distal end side of the stored and locked intermediate rod.

SUMMARY OF THE INVENTION A fishing rod according to the present invention has a base rod 1 having a fitting inner surface 11 at a distal end, a fitting outer surface 21 at a base end, and a fitting inner surface at a distal end. 22. A fishing rod including a plurality of intermediate rods 2 which are freely inserted into and retracted from the original rod 1, wherein the intermediate rod 2 At least the fitting outer surface 21 of the large-diameter-side intermediate rod 2 is fitted to provide a holding surface 12 for locking the movement of the intermediate rod 2 in the longitudinal direction. The intermediate rod is provided with a knob 24 having a large diameter and a predetermined length protruding outward from the distal end edge of the adjacent large diameter rod at the time of storage, and holding the original rod 1 at the outer periphery of the knob 24. Opposite inner and outer surfaces of the rod 2 with elasticity between the outer surface of the distal end portion of the rod 2 and the inner surface of the large diameter rod adjacent to the intermediate rod 2 when the intermediate rod 2 is stored. , It is provided with a stop layer 25 shake suppressing the deflection vibration in the radial direction.

[0008]

When the fishing rod is used with a reduced length, for example, of the intermediate rods 2, the large-diameter intermediate rod is housed in the original rod 1, and the small-diameter intermediate rod is pulled out. The large-diameter-side intermediate rod housed is stored at the base end of the original rod 1
Since it is fitted to the holding surface 12 to lock the movement in the length direction, and the tip portion only suppresses the radial deflection,
In the base end portion, the movement of the stored intermediate rod in the length direction can be locked, and the retracted intermediate rod can be easily pulled out, so that the entire length can be adjusted quickly and immediately. Even if it is desired to increase the overall length, this length adjustment can be made quickly.

In addition, the deflection of the stored intermediate rod at the tip end side is controlled by providing a vibration-preventing layer 25 that suppresses radial deflection by bending in a state of elasticity. Even if there is a dimensional error in the radial direction between the outer surface of the tip of the intermediate rod 2 to be held and the inner surface of the large-diameter side rod adjacent to the intermediate rod 2 when the intermediate rod 2 is stored, this radial dimension The error is absorbed by elastically deforming the anti-sway layer 25, and the radial deflection on the distal end side of the large-diameter-side intermediate rod can be effectively suppressed. Since the run-out can be suppressed without repeating the dimensional adjustment between the outer surface and the fitting inner surface of the adjacent large-diameter side rod at the time of storage of the intermediate rod 2, the workability can be improved and the cost can be reduced. It is.

And an intermediate rod 2 held on the original rod 1
The distal end portions of a and 2b are elastically opposed to the inner surface of the front outer surface 23 facing the inner surface of the fitting of the large diameter rod at the time of storage, so that radial deflection is suppressed by bending. That is, the steady rest layer 25 is provided.

In the above configuration, the holding surface 12 provided on the original rod 1 is formed separately from the original rod 1. That is, as shown in FIG. 1, a first holding cylinder 5 formed by fitting an inner screw 51 on one end inner surface and a sleeve 52 having a large diameter holding surface 12 on the other end inner surface, Using the second holding cylinder 6 having the surface 12, the first holding cylinder 5 is inserted into the end of the rod of the original rod 1, and the holding surface 12 of the first holding cylinder 5 is inserted.
The fitting outer surface 21 of the large-diameter intermediate rod 2a is fitted to lock the movement of the intermediate rod 2a in the longitudinal direction, and the butt plug 4 is screwed to the inner screw 51. And this ass plug 4
The second holding cylinder 6 is rotatably held on the inner surface of the first member so that it cannot move in the axial direction. The holding surface 12 of the second holding cylinder 6

When detaching by operation, the second
The holding cylinder 6 is moved in the axial direction along the detent groove 53 so that it can be attached to and detached from the original rod 1.

The tip of the large-diameter intermediate rod 2a is
It is built up in a range that does not come into contact with the fitting inner surface 11 to reduce a dimensional difference between the fitting inner surface 11 and the tip of the large-diameter intermediate rod 2b. Mating inner surface 2

The stop layer 25 is formed. In addition, the above-mentioned build-up is made of the large-diameter-side intermediate rod 2a, 2
Although the paint is thickly applied to the outer surface of the distal end portion b, it may be formed integrally when the large diameter intermediate rods 2a, 2b are manufactured. That is, a narrow prepreg similar to the prepreg to be formed in a wide width may be overlapped on the outside of one end of the wide prepreg, wound around the core bar, and integrally formed by pressure sintering as usual.

The anti-sway layer 25 is formed by, for example, electrodepositing a micro hair body. More specifically, an adhesive is applied to the outer surface of the front outer surface 23 and the adhesive is negatively charged, and a sieve containing a large number of micro hairs is arranged above the front outer surface 23. Then, the micro hairs in the sieve are positively charged, and the sieve is moved to drop the micro hairs,
The micro hairs are attached to the adhesive layer in an upright manner by the weight of the micro hairs and the suction force in an electric field.
In this case, the strength of the implanted micro hair can be increased by spraying an adhesive onto the micro hair after the micro hair is implanted.

Since the anti-sway layer 25 is provided to suppress the run-out by bending, even if there is an error in the cutting position of the adjacent large-diameter side rod and there is a dimensional error in the radial direction on the fitting inner surface, this radial direction The microscopic body of the steady layer 25 is elastically deformed to absorb the dimensional error, and the radial deflection on the distal end side of the large-diameter intermediate rods 2a, 2b can be effectively suppressed. Since there is no need to repeat the dimensional adjustment with the fitting inner surface of the adjacent large diameter rod at the time of storage, it is possible to improve the workability and provide it at low cost.

In the embodiment described above, five intermediate rods 2 are used, and of these intermediate rods, two large-diameter intermediate rods 2a and 2b are provided with the anti-sway layer 25. The number of intermediate rods provided with the steady rest layer 25 is not particularly limited.
