BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod and a manufacturing method thereof.

[0002]

2. Description of the Related Art Generally, a hollow fishing rod in which a fishing line is passed through a hollow portion of the fishing rod is widely known. With such a fishing rod, wet fishing line may adhere to the inside of the rod pipe,
Various methods have been adopted because the inner surface of the rod tube wears, sliding resistance increases, and operability deteriorates.

For example, a plurality of ceramic guide rings are formed at predetermined intervals so as to protrude to the inner peripheral surface, or Kevlar, glass, carbon, boron, aluminum fibers, etc. are impregnated with a synthetic resin. A means of installing a spiral body inside the fishing rod is adopted. Fluoride

No. 58).

[0004]

However, even if the guide portions are arranged at a predetermined pitch, when the pitch is large, the fishing line 101 adheres to the inside of the rod pipe 102 or scratches the inner surface of the rod pipe. Sliding resistance may increase and operability may deteriorate (see FIG. 7). Further, since the guide portion 103 is formed so as to project inward, seawater, dust, and the like may collect between the guide portions, which makes cleaning difficult. Also, those described in JP-A-5-268858
Simply applied the coating material mixed with fluororesin particles
Since it is only a thing, there is a risk that the paint will peel off. It
In addition, there is a problem that the weight increases by the amount of the paint material.
There is.

The present invention has been made in view of the above-mentioned problems. As a result, the fishing line adheres to the inside of the rod pipe or the inner surface of the rod pipe is damaged without forming a guide portion inside the rod pipe. An object of the present invention is to provide a hollow rod that can prevent the fishing line from being damaged.

[0006]

According to the present invention, there is provided a medium-strength rod which is constructed by joining a plurality of rod pipes and allows a fishing line to be inserted into the rod pipe. The innermost layer of the rod pipe is made of ceramics. Spherical body and solid lubricating powder are dispersed; and it is composed of multiple rod tubes joined together

[0007]

[Operation] The rod pipes are spliced together, and the fishing line can be inserted into the rod pipes. Then, fishing will be performed, but at this time, the innermost layer of the rod tube is formed by dispersing the solid lubricating powder having water repellency and lubricity and the ceramic spherical body having abrasion resistance, so that it becomes wet. It is possible to prevent the fishing line from adhering to the inside of the rod tube, the inner surface of the rod tube to be scratched and the fishing line to be scratched, and the sliding resistance of the fishing line to be increased to deteriorate the operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of a hollow fishing rod according to the present invention. Reference numeral 1 in the figure is the innermost layer, and the innermost layer 1
A circumferential carbon fiber 2, an axial carbon fiber 3, a circumferential carbon fiber 4, and an axial carbon fiber 5 are sequentially wound around the outer periphery of the. The innermost layer 1 is composed of solid lubricating powder 6 of tetrafluoroethylene resin and spherical alumina fine particles 7. The solid lubricating powder 6 has excellent water repellency and slidability, and the spherical alumina fine particles 7 have excellent wear resistance. Therefore, when the fishing line is used, the fishing line adheres to the inner peripheral surface of the rod pipe or the inner surface of the rod pipe. It is possible to prevent operability from being deteriorated due to damage to the fishing line and damage to the fishing line, or increase in sliding resistance of the fishing line.

Next, a method of manufacturing the hollow fishing rod according to the present invention will be described. First, in FIG. 2, a solid lubricating powder 6 (average particle size: 35) of tetrafluoroethylene resin (PTFE) is provided for one round of the innermost layer of the prepreg sheet 11 of carbon fibers in the circumferential direction.
μm) and spherical alumina spherical fine particles 7 (average particle size 30 μm
What is kneaded in a weight ratio of 3: 7 with m) is uniformly dispersed. The weight ratio is preferably 3: 7, but is not particularly limited to this. Thereafter, the solid lubricating powder 6 and the alumina spherical fine particles 7 which are ceramic spherical bodies are embedded in the prepreg sheet 11 by heating and pressing with a release paper interposed. Then, the excess powder is removed and collected.
Next, a release agent in which polytetrafluoroelastin telomer is dissolved in a solvent is applied to the mirror-finished core metal 12. Furthermore, acetone is mixed with epoxy resin as a diluent on this periphery,
An adhesive having a reduced viscosity is uniformly applied in a thickness of 10 to 15 μm and dried. Then, the prepreg sheet 11 in which the solid lubricating powder 6 and the alumina spherical fine particles 7 are dispersed is wound around the outer periphery of the adhesive, and the carbon fiber 3 in the axial direction, the carbon fiber 4 in the circumferential direction, and the carbon fiber in the axial direction are further wound. The carbon fiber 5 of 1 is sequentially wound. A winding tape (not shown) is wound around this outer periphery and heated and baked by a conventional method. Then, the cored bar is pulled out, and the winding fastening tape (not shown) is peeled off. As a result, the rod tube is formed. Since the innermost layer 1 (FIG. 1) of this rod tube is formed of solid lubricating powder 6 of tetrafluoroethylene resin and alumina spherical fine particles 7 of ceramic spherical body, it is smooth and has good gloss, water repellency, and sliding property. It has excellent dynamic and wear resistance.

Although the solid lubricant powder of tetrafluoroethylene resin is used in the above embodiment, the present invention is not limited to this, and the silicon powder (average particle diameter 20 μm) is used. May be

As shown in FIG. 4, solid lubricant powder 6 of PTFE and alumina spherical fine particles 7 which are spherical ceramics are used on one side of a cut ultrathin glass cloth prepreg (0.03 mm in thickness) 21 in a weight ratio of 3: The one kneaded in No. 7 is uniformly dispersed. The weight ratio is 3:
It is desirable that the number be 7, but the number is not particularly limited to this. Then, on the outer circumference of the innermost layer 1 formed of the glass cloth prepreg 21, the carbon fiber 22 in the axial direction,
The circumferential carbon fibers 23, the axial carbon fibers 24, and the circumferential carbon fibers 25 are sequentially wound.

Next, a third embodiment of the present invention is shown in FIG.
As shown in FIG. As shown in FIG. 5, on the release paper 28, the same epoxy resin 26 as the epoxy resin contained in the prepreg sheet forming the rod tube is formed in a film shape, and the solid lubricating powder 6 is formed on the film resin. And a mixture of spherical alumina fine particles 7 are uniformly dispersed. Next, this film-like resin was cut together with the release paper into a size corresponding to one round of the innermost layer of the rod tube, and this was cut into an innermost layer of the prepreg sheet 11 constituting the rod tube as shown in FIG. Then, the solid lubricant powder 6 and the alumina spherical fine particles 7 are transferred onto the prepreg sheet 11 together with the film-shaped resin, and the release paper 28 is removed. Then, the solid lubricating powder 6 and alumina spherical fine particles 7
The prepreg sheet 11 to which is transferred is wrapped around the core metal 12 coated with a release agent and an adhesive, and thereafter, the rod tube is formed by heating and firing by a conventional method.

The solid lubricant powder is not limited to PTFE, but silicon powder (average particle size 20
(μm) may be used. At this time, the weight ratio of the silicon powder and the spherical alumina fine particles is preferably 1: 3, but is not particularly limited thereto.
