Description

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 out guide, and more particularly to a fishing rod having an out guide which can be easily removed for repair.

[0002]

2. Description of the Related Art In recent years, the fishing population has greatly increased, and fishing itself tends to be a sport or fashion. For this reason, it has become a major proposition to reduce the weight of fishing gear, particularly fishing rods, in order to make it as easy to handle as possible. In order to reduce the weight of the fishing rod, not only the weight of the rod itself but also the weight of the line guide has a great effect.

[0003] This is because the use of many yarn guides increases the overall weight. Therefore, instead of a metal thread guide using a heavy material, a synthetic resin thread guide using a light material was developed. Synthetic resin thread guides are much lighter than metal guides, greatly contributing to the reduction of rod weight. In general, synthetic resins or plastics are advantageous in terms of cost. Further, since the synthetic resin thread guide is easy to mold, there is a relatively high degree of freedom in designing the outer shape, and there is an advantage in terms of downsizing. As described above, the weight reduction and the miniaturization have made it possible to extremely reduce the so-called "problem of the tip" which is a serious problem.

Furthermore, if a mold is selected for ease of molding, the shape can be freely set, so that a yarn guide having a smooth outer surface with less thread entanglement can be obtained. Thus, the synthetic resin yarn guide is extremely useful, but has the following problems. For example, this is a case where a fishing rod equipped with an out guide, particularly a fishing rod, is repaired. Generally, when one of the out guides attached and fixed to a rod breaks down, the out guide to be repaired must be removed from the rod pipe in order to repair the out guide. If the breakdown is the top guide at the tip of the tip, it is necessary to remove it. In addition, even if one of the floating guides arranged on the tip rod is broken, it is necessary to remove the top guide.

Further, if a rod other than the head rod, for example, a lip guide fixed to the tip of the ear rod breaks, it is necessary to remove the leading out guide, that is, the top guide of the head rod and its floating guide. There is. Of course, the same can be said for rods other than the head rod and the ear rod. In extreme cases, the entire rod can be disassembled. When removing the out guide at the time of such repair, in the case of the conventional metal thread guide, remove it by forcibly pulling it out using a gripper or other gripping tool, or remove it similarly while heating it with hot air using a dryer Was completed.

However, it is very difficult to remove the synthetic resin guide from the rod tube. This is because, in most cases, epoxy resin or urethane resin is used as an adhesive and cannot be removed even by heating. In addition, when the hot air of the dryer is used, there is a risk that the synthetic resin guide itself may be deformed due to excessive heating, and at the extreme, a part of the guide may be softened and fixed to the rod pipe.
However, if the guide is made of plastic to be broken or replaced, there is no problem if it is deformed, but if it is simply removed for the convenience of repairing another synthetic resin guide, it will be attached later It is uneconomical to fix it.

[0007]

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a fishing rod having a line guide according to the present invention will be described below with reference to the drawings. Here, the yarn guide is an out guide. FIG. 1 shows a fishing rod for drawing provided with an out guide according to the present invention.
2 shows a part of the ear rod 3. A top guide 2 is fixedly attached to the tip of the tipping rod 1 (that is, the top guide 2 is externally fixed to the rod pipe). A certain so-called mouth guide 4 is fixedly attached (that is, the mouth guide 4 is extrapolated and fixed to the rod pipe).

Between the top guide 2 and the mouth guide 4, a plurality of movable yarn guides, that is, floating out guides 2A are provided. Similarly, although not shown, a plurality of floating out guides are similarly arranged on the lip guide 4 and the lip of the third rod on the hand side of the ear rod 3, and the same applies to the following rods. The out guide of the present invention attached to the rod pipe is a so-called synthetic resin out guide formed using synthetic resin as a material.

As a material of the synthetic resin out guide, a synthetic resin material (for example, polyamide synthetic resin, polyamide / glass fiber reinforced synthetic resin, polyamide / carbon fiber reinforced synthetic resin, polycarbonate, polyacetal, etc.) is used. . The synthetic resin out guide includes line guides 22 and 42 for guiding the fishing line and legs 21 and 41 to be attached to the rod pipe (FIGS. 3 and 5).
reference). The legs 21 and 41 are provided with through holes 21A and 41A for inserting a rod pipe. This foot is
In the top guide 2, the tip of the through hole 21A is closed, and the tip of the spike is abutted on the closed portion to be attached.

On the other hand, in the mouth guide 4 fixed not at the top guide but at the tip of the ear rod, the through hole 41A of the foot 41 is open (see FIG. 5). The mouth guides are attached and fixed to rods other than the tip rod, but in this case also, the through holes in the feet are open.
The yarn guide portions 22 and 42 of the top guide and the mouth guide are provided with wear-resistant guide rings 22A and 42A,
Help guide the fishing line.

Now, it is assumed that one of the floating out guides, which is conveniently disposed in front of the top guide, is broken. In order to repair the floating out guide, it is necessary to remove it from the spike, so the top guide is removed, and the broken floating out guide is also removed. Therefore, the top guide is fixed with an adhesive having a condition that it can be easily removed.

The condition is to employ an adhesive which can be hydrolyzed. Here, as the adhesive which can be hydrolyzed, for example, a cyanoacrylate-based adhesive (for example, JP-A-8-209074, JP-A-8-143)
No. 823, etc.).
In addition, this cyanoacrylate-based adhesive is a so-called 2
-It is mainly composed of cyanoacrylate, and is also called an instant adhesive because it rapidly cures by anionic polymerization in the presence of a basic substance or the like. And since it has such a property that it cures instantaneously, it is extremely efficient to attach the yarn guide to the rod pipe in the production process.

By the way, since the adhesive which can be hydrolyzed is rapidly decomposed by adding water, the out guide can be easily removed from the rod pipe. By using such an adhesive, it is possible to remove the metal out guide without using hot air, a yacht or the like as in the case of removing the conventional metal out guide. In other words, it can be removed using handy hot water. Incidentally, hot water is used because it has an action to promote hydrolysis.

Next, FIG. 2 shows a method of removing the top guide from the spike. More specifically, as shown in the figure, the top guide 2 is immersed in the hot water of the container 6 while the top guide 2 is fixed to the tip rod 1 which is a rod tube. And
It is left in hot water W of 90 to 100 ° C. for about 30 minutes. Then, the adhesive R gradually absorbs water in the hot water W to cause hydrolysis, and as a result, the top guide 2 comes off the rod pipe. After removing the top guide 2,
What is necessary is just to remove a broken floating out guide and repair it.

At this time, since the synthetic resin material of the top guide 2 is not easily deformed at about 100 ° C., it is necessary to repair or replace the floating out guide and then reattach the top guide 2 to the tip of the tip rod. Can be. In general, as described above, a cyanoacrylate-based adhesive has a property that the adhesive is instantaneously cured. If a further curing speed is expected when the out guide is attached and fixed to the rod tube, it is preferable to include an ultraviolet curable resin in the cyanoacrylate adhesive. By irradiating the ultraviolet rays, the curing speed is doubled, and the productivity is further improved.

On the other hand, since ultraviolet curable resins do not hydrolyze, by including them, it is also advantageous in that they function to suppress hydrolysis when moisture adheres in a normal use environment. The curing of the cyanoacrylate adhesive is promoted by including a curing accelerator. However, when the cyanoacrylate adhesive reacts violently with moisture in the air during installation, a white smoke (white fine particles) phenomenon occurs, so when installing it on a pole tip, use a cyanoacrylate adhesive so that there is no such phenomenon. A curing accelerator is included, and curing is performed before white smoke is generated.

Here, as the curing accelerator, for example, a polyalkylene oxide and its derivative, a crown ether and its derivative, a silacrown ether and its derivative, a calixarene derivative and the like are used as a polymerization accelerator. For example, hydroperoxide,
Organic peroxides such as peroxyester, ketone peroxide, peroxyketal, dialkyl peroxide and peroxydicarbonate are used.

FIG. 3 shows a state in which the top guide is attached to the tip of the spike using the cyanoacrylate adhesive after the repair. When the cyanoacrylate adhesive R is applied to the tip region of the tip rod 1 and the tip rod 1 is quickly inserted into the through hole 21A of the top guide 2 and maintained as it is, the adhesive hardens almost instantaneously. As described above, the cyanoacrylate-based adhesive R is extremely efficient when attaching the out guide to the rod pipe. However, since the cyanoacrylate adhesive R becomes relatively hard as a layer after curing,
From the viewpoint of bending of the rod pipe, it is preferable to set the hardness in the range of 30 to 80 [(Shore D) JIS].

When the tip rod 1 is inserted into the through hole 21A of the top guide 2 as described above, the orientation of the top guide may be distorted. However, by increasing the viscosity of the adhesive, the curing is slightly delayed. It is possible to make fine adjustments such as the orientation of the top guide. For this purpose, the viscosity of the cyanoacrylate adhesive before curing is 400 to 1
000 cp (400 to 1000 mPa · s).

By the way, it is conceivable that water adheres to the top guide attached to the rod tip during use at the fishing spot. In this case, the water penetrates into the adhesive between the foot of the top guide and the rod pipe. Sometimes. Normally, the attached water cannot penetrate into the adhesive interposed between the rod pipe and the top guide, but it is also preferable to take measures to prevent it in consideration of the emergency. That is.

For example, a sealing portion for preventing intrusion of moisture or the like may be provided at an end of a foot portion externally inserted into a rod tube of an out guide (top guide or mouth guide). For the formation of this sealing portion, a synthetic resin that does not hydrolyze, for example,
A two-pack type epoxy resin, an ultraviolet curable resin, or the like is used. However, considering the case where the out guide is removed, it is important to form the out guide so that it can be easily removed later. Particularly, from the viewpoint of the releasability at the time of removal, an ultraviolet curable resin is preferable. As described above, when the out guide is detached by immersing it in hot water as described above, there is an advantage that the ultraviolet curable resin can be peeled off from the rod tube at once using a cutter knife.

FIG. 4 shows a configuration in which a sealing portion 5 is provided on an out guide (top guide 2) of the tip rod 1. By forming the sealing portion 5 in this manner, the layer of the adhesive R is shut off from the outside air, and the anaerobic state is always maintained. In this case, it is needless to say that the sealing portion 5 should be as small as possible as long as it can prevent intrusion of moisture and the like.

FIG. 5 shows a configuration in which a sealing portion 5 is provided on an out guide (mouth guide 4) of the ear-holding rod 3. in this case,
Unlike the top guide, the foot 41 of the lip guide 4
Both ends are easily exposed to air. Therefore, foot 4
The sealing portions 5 are formed at both ends of the first member 1. Next, an experiment was conducted in which the top guide attached to and fixed to the spikestick using a cyanoacrylate-based adhesive was removed.

In hot water for 30 minutes. Thereafter, the synthetic resin top guide was grasped by hand and pulled out from the tip of the tip. As a result, it easily came off the tip rod.

Next, a similar experiment was carried out using a cyanoacrylate-based adhesive (TB1721C) (manufactured by Three Bond Co., Ltd.) instead of the adhesive. The result was similarly easily detached from the spike.

Although the present invention has been described above, the present invention is not limited to the embodiments but can be freely modified as long as it meets the purpose. For example, various additives such as a stabilizer, a thickener, a plasticizer, a filler, and a colorant can be appropriately added to the cyanoacrylate adhesive. In addition, from the viewpoint of removal, the adhesive as in the present invention can be used for not only the swing rod but also other rods, for example, the top guide of the through rod.

[0038]

According to the present invention, since a hydrolyzable adhesive is used, the adhesive can be easily removed by dipping in hot water or the like, which is extremely convenient for repair.
