Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod, and more particularly to a fishing rod in which a fishing line guide is detachably attached to a rod body and a method for manufacturing the fishing rod.

[Conventional technology]

Generally, in a fishing rod, a fishing line guide is arranged in a fixed state at the tip of each splicing member that constitutes the fishing rod, and on the other hand, the fishing line guide moves at a predetermined position by moving in the rod axis direction in the middle part of a thin portion such as a tip or a portion below the tip. It is used by being placed in a detachable manner.

However, in such a conventional fishing rod, there is a problem that the fishing line guide detachably arranged on the rod body rotates or moves in the axial direction during fishing.

As a fishing rod which prevents the rotation or movement of such a fishing line guide, Japanese Utility Model Publication No. 58-2222 and Japanese Utility Model Publication No. 62-
Those disclosed in Japanese Patent No. 39665, Japanese Utility Model Laid-Open No. 64-45964, etc. are known.

That is, in the fishing rod disclosed in Japanese Utility Model Publication No. 58-2222, a mounting portion formed of irregularities is formed on the outside of the rod body, and the irregularities formed on the inside of the fishing line guide mounting cylinder are engaged with the irregularities. The rotation of the fishing line guide is prevented.

Further, in the fishing rod disclosed in Japanese Utility Model Publication No. 62-39665, a heat-shrinkable synthetic resin tape is heat-shrinked on the outer periphery of the rod body to form a fitting portion, which is fitted to the tape. The fishing line guide mounting cylinder is fitted, and the elastic force of the tape prevents the fishing line guide from rotating and moving.

In the fishing rod disclosed in Japanese Utility Model Laid-Open No. 64-45964, a synthetic resin paint is used to form a mounting portion composed of a surface layer having elasticity on the outer periphery of the rod main body, and a fishing line guide mounting cylinder is formed on the surface layer. And the elastic force of the surface layer prevents the fishing line guide from rotating and moving.

[Problems to be Solved by the Invention]

However, in the fishing rod disclosed in Japanese Utility Model Publication No. 58-2222, since the unevenness is formed on the outer side of the rod main body, the rod diameter of this mounting portion becomes large, and accordingly, the mounting cylinder of the fishing line guide becomes large. As a result, there is a problem that the weight is increased, the bending of the rod main body is deteriorated, the stress is concentrated on the mounting portion, the condition of the fishing rod is deteriorated, and the rod is easily broken.

Further, in the fishing rod disclosed in Japanese Utility Model Publication No. 62-39665, since a heat-shrinkable synthetic resin tape is fitted on the outer periphery of the rod body, the outer diameter dimension of the mounting portion easily varies, and the setting position of the fishing line guide is It is easy to slip or the tape peels off,
Further, there is a problem that the mounting portion made of the tape is plastically deformed.

In the fishing rod disclosed in Japanese Utility Model Laid-Open No. 64-45964, the elastic force of the surface layer formed on the rod body prevents the fishing line guide from rotating and moving. Due to elastic deformation of the surface layer, the mounting cylinder sticks to the surface layer when it is inserted too deeply and is removed, and even after the mounting cylinder is pressed into the surface layer, the surface layer has elasticity, so the load on the mounting cylinder As a result, the surface layer is further deformed and the fishing line guide rotates.

As a result of earnest research to solve the above-mentioned conventional problems, the present inventor has determined that the static friction coefficient of the mounting portion of the fishing line guide, which is to be fitted with the mounting cylinder, is an extremely thin coating layer integrally vulcanized and formed on the rod body. It has been found that the rotation and movement of the fishing line guide can be sufficiently prevented and the mounting and dismounting of the mounting barrel to and from the mounting portion becomes very easy by increasing the size.

The present invention has been made based on such knowledge, and can reliably prevent the rotation and movement of the fishing line guide, and easily attach and detach the fishing line guide to and from the rod body without deteriorating the fishing rod condition. An object of the present invention is to provide a fishing rod that can be manufactured and a method for manufacturing the fishing rod.

〔Example〕

Hereinafter, details of the present invention will be described with reference to embodiments shown in the drawings.

1 to 3 show an embodiment of a fishing rod of the present invention, in which reference numeral 11 denotes a rod main body formed by winding a prepreg in which high strength fiber is impregnated with a synthetic resin. ing.

Here, the high-strength fiber is, for example, carbon fiber, aramid fiber, glass fiber or the like, and the synthetic resin is epoxy resin, polyester resin or the like.

A mounting portion 13 is formed on the outer periphery of the rod body 11 at predetermined intervals, and a fishing line guide 15 is arranged in the mounting portion 13.

The fishing line guide 15 is composed of a guide portion 19 in which a guide hole 17 for inserting a fishing line is formed, and a mounting cylinder 21 supporting the guide portion 19, and the mounting cylinder 21 is connected to the cylindrical portion 23 of the guide portion 19.
The guide portion 19 is fixed to the mounting cylinder 21 by being inserted into.

Further, on the inner circumference of the mounting cylinder 21, in the axial direction of the mounting cylinder 21,
A large number of fine sawtooth-shaped irregularities 25 are formed.

In this embodiment, the guide portion 19 is made of a metal material such as stainless steel, and the mounting cylinder 21 is made of synthetic resin.

Thus, in this embodiment, the mounting portion 13 is formed by vulcanization curing integrally with the rod body 11, and is formed by the coating layer 27 made of an extremely thin rubber-like substance having a static friction coefficient larger than the static friction coefficient of the rod body 11. Has been formed.

That is, the coating layer 27 is made of chlorosulfonated polyethylene, chloroprene rubber, other rubber-like synthetic substances, rubber-like substances such as natural rubber, and the thickness of the coating layer 27 is 5
It is said to be ~ 80 microns.

The depth of the irregularities 25 formed on the inner circumference of the mounting cylinder 21 described above is at least larger than the thickness of the coating layer 27.

The fishing rod configured as described above is manufactured as described below.

That is, first, after winding a prepreg obtained by impregnating high strength fiber with synthetic resin around a mandrel,
The rod body 11 is formed by heating and firing at a temperature of 120 to 160 ° C.

Thereafter, the surface of the rod body 11 is surface-polished by using a scotch, a sander or the like, and then a base treatment such as degreasing is performed.

Then, an epoxy resin, a urethane resin or the like is undercoated on the rod body 11, the surface of the rod body 11 is surface-polished by using a scotch, a sander or the like, and then a base treatment such as degreasing is performed.

After that, the coating portion 27 is formed on the mounting portion 13 of the rod body 11 by vulcanizing and curing the above-mentioned chlorosulfonated polyethylene, chloroprene rubber, other rubber-like synthetic substances, and rubber-like substances such as natural rubber.

For example, in the case of chlorosulfonated polyethylene,
Vulcanizing agents including acid acceptors for litharge (oxide salts), magnesium sulfide, and other polybasic substances are used, and as the solvent, toluene, butanol, etc. are used.

The fishing rod was prepared by melting the main agent and the vulcanizing agent in a solvent.
Liquid substances are preferred.

Further, the coating layer 27 is formed by a lacquer coating, a brush coating, a spray coating or the like, but the lacquer coating is suitable for easily and reliably forming the extremely thin coating layer 27.

In addition, vulcanization curing is performed, for example, in an atmosphere of 80 to 100 ° C.
It is performed by heating for ~ 120 minutes.

The resin for forming the coating layer 27 may be applied to the entire surface of the rod body 11 or a part thereof, and may be scored in the axial direction or may be uneven in the circumferential direction.

Further, it is preferable to mix known particles or a reinforcing material, but it is not preferable to mix an additive that lowers the coefficient of static friction of the surface.

In the fishing rod constructed as above, the rod body
11 is formed by winding a prepreg in which high-strength fiber is impregnated with a synthetic resin, and the mounting portion 13 is integrally vulcanized and cured on the rod body 11, and the static friction coefficient is larger than the static friction coefficient of the rod body 11. Since it is formed by the coating layer 27 made of an ultrathin rubber-like substance having the above, the rotation and movement of the fishing line guide 15 can be reliably prevented, and the fishing line guide 15 can be easily attached to and detached from the rod body 11. It becomes possible.

That is, in the fishing rod configured as described above, since the static friction coefficient of the mounting portion 13 into which the mounting cylinder 21 of the fishing line guide 15 is fitted is increased, it is possible to sufficiently prevent the rotation and movement of the fishing line guide 15. Moreover, it is possible to make mounting and dismounting of the mounting cylinder 21 to and from the mounting portion 13 extremely easy.

In addition, in the fishing rod configured as described above, simply the rod body
Since the coating layer 27 made of an extremely thin rubber-like substance is formed on the shaft 11, it is possible to prevent the weight of the fishing rod from increasing.

Further, since it is the coating layer 27 made of an extremely thin rubber-like substance, the bending of the rod main body 11 does not deteriorate, stress concentrates on this portion, the condition of the fishing rod is deteriorated, and the rod is broken. It won't be easy.

Further, since it is the coating layer 27 made of an extremely thin rubber-like substance, the outer diameter dimension is unlikely to vary, and the fishing line guide can be reliably set.

In addition, the rod body 11 has a coating layer made of an extremely thin rubber-like substance.
Since 27 is integrally vulcanized, neither peeling nor plastic deformation occurs.

In the fishing rod configured as described above, the thickness of the coating layer 27 made of an extremely thin rubber-like substance is set to 5 to 80 μm, so that the rotation and movement of the fishing line guide 15 can be prevented most reliably. Further, the fishing line guide 15 can be easily attached to and detached from the rod body 11.

That is, when the thickness of the coating layer 27 made of an extremely thin rubber-like substance is less than 5 μm, the fishing line guide 15 can be easily attached to and detached from the rod body 11, but in this case, the coating layer Since the wall thickness of 27 is too thin, it becomes very difficult to impart a predetermined coefficient of static friction to the coating layer 27.

On the other hand, the thickness of the coating layer 27 made of an extremely thin rubber-like substance
If it exceeds 80 μm, if the mounting cylinder 21 of the fishing line guide 15 is strongly fitted, the elastic deformation of the coating layer 27 causes it to go too deeply, and the mounting cylinder 21 may be removed when it is removed.
The coating layer 27 has elasticity even after the mounting tube 21 is fitted into the coating layer 27, so that the coating layer 27 is further deformed by the load on the mounting tube 21, and the fishing line guide 15 May rotate.

Furthermore, in the fishing rod configured as described above, the mounting cylinder 21
Since the unevenness 25 having a thickness larger than that of the coating layer 27 made of at least an extremely thin rubber-like substance is formed on the inner periphery of the mounting cylinder 21, the mounting cylinder 21 can be securely locked to the coating layer 27, and The mounting cylinder 21 can be supported not only by the coating layer 27 but also by the surface of the rod body 11. In this case, since the mounting layer 21 alone does not receive the mounting cylinder 21, the coating layer 27 is unlikely to peel off, and rotation of the mounting cylinder 21 is reliably prevented. Further, it becomes relatively easy for the mounting cylinder 21 to move in the axial direction of the mounting portion 13, and the mounting cylinder 21 can be easily attached and detached.

In the fishing rod constructed as described above, the coating layer 27
However, since it is made of a rubber-like substance, it does not absorb water, and it is very easy to attach and detach the mounting cylinder 21 even if it is used for a long time.

Then, in the method for manufacturing a fishing rod of the present invention, a prepreg impregnated with synthetic resin in high-strength fiber is wound, and this is heated and fired to form a rod main body 11, and then a mounting portion of the rod main body 11 is attached.
Surface polishing is applied to 13 and, after that, to the mounting portion 13 of the rod body 11,
Since the coating material made of a rubber-like substance is vulcanized and cured to form the coating layer 27 made of an extremely thin rubber-like substance, there is an advantage that the above-mentioned fishing rod can be easily formed.

4 and 5 show another embodiment of the fishing rod according to the present invention. In this embodiment, the mounting cylinder 31 of the fishing line guide 15 is shown.
No unevenness is formed on the inner side of, and it is merely a smooth surface.

With the fishing rod constructed as described above, it is possible to obtain substantially the same effect as that of the embodiment shown in FIG.

〔The invention's effect〕

As described above, in the fishing rod according to claim 1, the rod body is
An ultra-thin rubber that has a static friction coefficient greater than the static friction coefficient of the rod body, and is formed by winding a prepreg in which high-strength fibers are impregnated with synthetic resin and the mounting portion is integrally vulcanized and cured. Since the fishing line guide is formed of a coating layer made of a granular material, the fishing line guide can be reliably prevented from rotating and moving, and the fishing line guide can be easily attached to and detached from the rod body.

Further, in the fishing rod according to claim 2, since the wall thickness of the coating layer is set to 5 to 80 μm in claim 1, rotation and movement of the fishing line guide can be prevented more reliably, and the fishing line guide to the fishing rod main body can be prevented. It can be attached and detached more easily and the rod condition can be maintained well.

In the method for manufacturing a fishing rod according to claim 3, a high-strength fiber is wrapped with a prepreg impregnated with a synthetic resin, and the prepreg is heated and fired to form a rod main body, and then a mounting portion of the rod main body is surface-polished. After that, the coating material made of a rubber-like substance is vulcanized and cured on the mounting portion of the rod body to form a coating layer made of an extremely thin rubber-like substance, so that the fishing rod according to claim 1 can be easily carried out. It has the advantage that it can be formed.
