DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod provided with a projection for guiding a fishing line on an inner peripheral surface of a rod tube.

[0002]

2. Description of the Related Art In general, a fishing rod through which a fishing line is inserted into a rod pipe is widely known. As such a through fishing rod, there has been proposed a conventional fishing rod in which an annular support member provided with a fishing line guide member inside a tapered rod pipe is positioned at a predetermined position by a throwing operation, and is bonded and fixed as required. (JP-A-56-127032).

Further, by fixing the outer peripheral surface of the fishing line guide member or the annular support member to the minute uneven portion formed integrally with the inner peripheral surface of the rod pipe, the fixing force of the fishing line guide in the rod pipe is improved. (Japanese Unexamined Patent Publication No. Hei 7
No. 107885).

Further, a projection made of the same material as the rod pipe material is integrally formed on the inner peripheral surface of the rod pipe (Japanese Utility Model Laid-Open No. 5-8).
No. 8259), and a protrusion formed on the inner peripheral surface of a rod pipe by a material reinforced with a ceramic fiber or a twisted yarn different from the rod pipe material (Japanese Patent Laid-Open No. 7-39277) has been proposed. By forming the protrusions on the inner peripheral surface of the rod pipe in this way, the contact area of the fishing line guided in the rod pipe is reduced, and by forming the protrusions in a helical shape, water accumulates in the rod pipe. There is something to prevent.

[0005]

[0006] In the fishing rod, the algae and the like attached to the fishing line during fishing may be caught in the fishing rod and adhere to the inner peripheral surface of the fishing rod. Of course, even when the fishing rod is washed with water, the dust may remain. If the fishing rod is stored without noticing the adhesion of the dust, the dust or the like dries and adheres to the fishing line guide projection provided in the fishing rod. For this reason, when the fishing rod is used next time, winding and unwinding of the fishing line may be hindered, or it may not be possible to insert the fishing line into the rod tube.

Further, if the sticking dust or the like is to be scraped out with a rod or the like, the work is performed in a groping state, so that the projection for guiding the fishing line and the inner peripheral surface of the rod pipe are damaged, which results in This may result in damage or cutting of the fishing line, or the rod itself may become unusable.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a through fishing rod which can easily and surely recognize the entrapment or adhesion of algae or the like to the inner peripheral surface of the rod tube from the outside.

[0008]

The present invention will be described with reference to FIG. 1 showing one embodiment of the present invention. However, the present invention is not limited to the illustrated embodiment.

According to the present invention, in a hollow fishing rod (1) having an inner peripheral surface provided with a projection (11) for guiding a fishing line, at least a tip of a rod tube (2, 3, 4) constituting a fishing rod. The above-mentioned object is achieved by forming the rod pipe (4) of a transparent material.

According to the present invention, whether or not algae or the like are caught or adhered to the inner peripheral surface of the rod pipe (4) can be confirmed from outside the rod pipe (4) through the transparent portion. When algae or the like are caught or attached, the removal operation can be performed while confirming the position. Fishing rod (1)
Even when the fishing line (6) is inserted into the inside, the working condition can be visually recognized from the outside of the rod pipe (4).

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. (First Embodiment) FIG. 1 shows a through fishing rod according to a first embodiment of the present invention. As shown in FIG. 1A, this through fishing rod 1 includes a rod tube 2 as a former rod,
It has an intermediate rod tube 3 attached to the rod tube 2 and a rod tube 4 as a head attached to the rod tube 3. A reel 5 is mounted on the reel sheet 2a of the rod tube 2, and the reel 5
The fishing line 6 drawn out of the fishing rod 1 is introduced into the fishing rod 1 from the entrance 7 and pulled out from the top guide 8 at the tip of the rod tube 4. In addition, the number of rod pipes can be changed as appropriate, and not limited to a swing rod, but may be a joint rod.

As shown in FIG. 1B, the rods 2, 3, 4
A spiral projecting portion 11 for guiding the fishing line 6 is formed on an inner peripheral surface of the fishing line. At least the rod tube 4 at the tip is formed of a transparent material, and the inner peripheral surface can be visually recognized from the outside. The rod tubes 2 and 3 are formed of a transparent or opaque material.

The rod tube 4 is manufactured by, for example, a method shown in FIG. That is, a known release agent or adhesive is applied to the outer peripheral surface of the cored bar 12, and a water-soluble resin tape 13 is spirally wound thereon at a predetermined interval in the axial direction of the cored bar 12. The resin tape 13 is extruded into a substantially semicircular or semielliptical cross section, and is wound so that its flat surface side is in close contact with the outer peripheral surface of the cored bar 12.

Next, a prepreg sheet 14 for forming a rod tube is wound around the outer periphery of the wound resin tape 13.
The prepreg sheet 14 is configured by impregnating a thermosetting synthetic resin into a reinforcing fiber. In the present embodiment, in particular, a transparent fiber such as a glass fiber is used as a reinforcing fiber, and a synthetic resin that becomes transparent after firing is used. Used respectively. Thereby, the rod tube 4 can be formed transparent. In addition,
As the reinforcing fibers, opaque ones such as carbon fibers and metal fibers may be used.

Subsequently, a pressure tape 15 is wound around the outer periphery of the prepreg sheet 14 under pressure by a conventional method, and the resulting semi-finished product is heated in a firing furnace to cure the thermosetting resin of the prepreg sheet 14. . Then the core metal 12
And the water-soluble resin tape 13 is melted and removed with a solvent or the like. Thereby, the inner peripheral surface of the rod pipe 4 having the protruding portion 11 is formed. Next, the pressure tape 15 is peeled off,
The exposed outer peripheral surface of the rod tube 4 (the outer peripheral surface of the cured resin molded body) is polished and a transparent paint is applied to finish.

When the rods 2 and 3 are formed to be transparent, they may be manufactured in the same procedure as described above. When the rod pipes 2 and 3 are not formed transparent, it is not necessary to use a synthetic resin which becomes transparent after curing.

The prepreg sheet is not limited to a single layer, but may be a plurality of layers. For example, a aligned prepreg sheet in which reinforcing fibers are oriented in the axial direction of the rod pipe, and an aligned prepreg sheet in which reinforcing fibers are oriented in the circumferential direction of the rod pipe, such that the former is sandwiched between the latter, for example. The former and the latter may be stacked one on another. In place of reinforcing fibers aligned in one direction, woven reinforcing fibers may be used, and various methods for forming rod pipes are known, such as winding or braiding reinforcing fibers around the outer periphery of a cored bar. Can be replaced by

A tape made of polyethylene or the like is wound around the outer peripheral surface of the metal core 12 in place of the water-soluble resin tape 13,
After de-centering 2, the tape may be pulled out from the inner peripheral surface of the rod pipe while being peeled off. The protrusion 11 is not limited to a spiral shape,
The annular protrusions may be formed at regular intervals in the axial direction of the rod tube 4. By spraying a powder of a fluororesin, a silicone resin, or a polymer thereof on the outer periphery of the resin tape 13 and embedding and exposing the inner surface of the rod tube during firing of the rod tube, a water-repellent surface is formed on the inner peripheral surface of the rod tube. It may be formed.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals.
As shown in FIG. 2A, in the present embodiment, the projection 21 for guiding the fishing line is formed of a material different from the constituent elements of the prepreg sheet 14 which is a material for forming the rod tube 4 itself. Is done. The point that at least the tip end of the rod tube 4 is made of a transparent material is the same as in the first embodiment described above.

Such a rod tube 4 is manufactured, for example, by a method shown in FIG. First, a water-soluble resin tape 13 is spirally wound around the outer circumference of the cored bar 12 at a predetermined interval in the axial direction of the rod tube 4, and a material 22 of the projecting portion 21 is filled in a gap between the resin tapes 13. Both ends are resin tape 13
And wrap it so that it overlaps or adheres closely. Material 2
For example, a material obtained by impregnating a synthetic resin into a reinforcing fiber using abrasion-resistant hard fiber (ceramic fiber or the like), twisted yarn, or the like can be used as 2. Instead of the material 22 having a substantially circular cross section shown in FIG. 2 (b), a cross tape 22 'having a rectangular cross section shown in FIG. 2 (c) may be used, and reinforcing fibers are aligned in one direction instead of the cross tape. A tape may be used. You may wind the thing which impregnated the synthetic resin in the Lilian braid reinforced with the above-mentioned hard fiber or twisted yarn.

Next, a prepreg sheet 14 for forming a rod tube
Is wound around an appropriate layer (four layers in the illustrated example) so that the direction of the reinforcing fiber alternates with the circumferential direction and the axial direction of the rod tube 2, and a pressure tape (not shown in FIG. 2) ) Is wound under pressure. Prepreg sheet 14
As in the first embodiment, a transparent or opaque reinforcing fiber impregnated with a thermosetting synthetic resin that becomes transparent after curing is used.

The semi-finished product obtained by the above procedure is heated in a firing furnace to cure the synthetic resin impregnated in the prepreg sheet 14. In the heating process, the synthetic resin impregnated in the material 22 and the prepreg sheet 14 respectively melt and harden, so that the material 22 and the prepreg sheet 14 are integrally joined to each other.

After the resin is cured, the core 12 is de-centered, and then the water-soluble resin tape 14 is melted and removed with a solvent or the like. As a result, a spiral projecting portion 21 made of a different material is formed on the inner peripheral surface of the rod tube 4. Thereafter, the pressure tape is peeled off from the outer periphery of the cured resin layer, and the exposed outer peripheral surface of the rod tube 4 is polished to apply a transparent paint to finish.

In the present embodiment, annular projections may be formed at regular intervals in the axial direction of the rod 4 instead of the spiral projections 21. In the above embodiment, the rod 4
The protrusion 11 of the same material or the protrusion 21 of a different material is formed on the inner peripheral surface of the fishing line 6 and is used as a guide for the fishing line 6, but the present invention is not limited to such a form. It may be configured as shown in FIG.

In the example of FIG. 3, an annular support member 31 is formed in a step different from that of the rod tube 4, and a fishing line guide 32 is provided at the center thereof. The support member 31 is made of, for example, synthetic resin, rubber,
The fishing line guide 32 is formed of a lightweight metal, a fiber-reinforced composite material, or the like, and the fishing line guide 32 is formed of a material having excellent wear resistance, for example, a ceramic, a hard metal or other various composite materials. The assembled support member 31 and the fishing line guide 32 are inserted into the inside of the rod tube 4, and the pawl 33 provided on the support member 31 is engaged with the inner peripheral surface 4 a of the rod tube 4 at a predetermined position to support the support member 31. 31 is fixed. The claws 33 are made of a hard material. In this example, the support member 31 and the fishing line guide 32
Corresponds to the projection for guiding the fishing line. An adhesive may be used for fixing the annular support member 31.

In the example of FIG. 4, a projecting portion 40 of a different material is formed on the inner peripheral surface of the rod tube 4, an annular support member 41 is provided inside the projecting portion 40, and a fishing line guide 42 is provided at the center. ing. The protrusion 40 can be formed in the same manner as the protrusions 21 and 21 ′ of FIG. 2, and includes the support member 41 and the fishing line guide 4.
The manufacture and fixing of 2 may be the same as in the example of FIG. In the example of FIG. 4 as well, the combination of the support member 41 and the fishing line guide 42 corresponds to the projection for fishing line guidance.

In the examples shown in FIGS. 3 and 4, the support members 31, 41 and the fishing line guides 32, 42 are formed integrally from a hard material such as ceramic, respectively, and the outer peripheral surface of the integrated member is formed. The rod and the inner peripheral surface of the rod tube 4 may be fixed to each other.

Further, in the example of FIG. 4, the ridge portion 40 may be integrally formed of the same material as the rod tube similarly to the projection portion 11 of FIG. It goes without saying that the rod pipes 2 and 3 other than the tip may be formed of a transparent material.

[0029]

As described above, according to the through fishing rod of the present invention, it is determined whether or not algae or the like is attached to the inner peripheral surface of the rod tube through the transparent portion of the rod tube. Since it can be easily checked from the outside of the rod, it is not necessary to notice the algae or the like getting caught in or sticking to the inside of the rod pipe and leaving it unattended. When algae are involved, the removal operation can be performed while checking the position, so there is no danger of the algae remaining, and the inner peripheral surface of the rod pipe may be erroneously damaged during the removal operation. Also less. Even when the fishing line is inserted into the fishing rod, the operation status can be visually recognized from the outside of the rod pipe, so that the operation of inserting the fishing line can be performed more easily than before.
