Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing line cushioning tool for cushioning a shock of a fish caught on a fishing hook due to abrupt pulling to prevent Harris breakage and fish mouth cutout, and a manufacturing method thereof.

[0002]

2. Description of the Related Art In recent years, the number of people who play outdoor sports has increased, and as one of them, fishing has become popular. Usually, fishing is performed by tying a hook at the tip of a fishing line.This fishing line is classified into Harris, which is directly tied to the fishing line, and road, which extends from Harris to the angler's hand. Various devices are provided between the threads. Since fish have a strong sense of caution, Harris has a smaller diameter than the line so that the fishing line will not be noticed by the fish. As a result, the Harris was sometimes cut off due to the sudden pulling of the fish that caught the hook.

Therefore, as a means for preventing the breakage of Harris, a fishing line cushion (commonly called cushion rubber) interposed between the road line and Harris is generally known. In this fishing line cushioning tool, both ends of an elastic filamentous body 20 are formed into a loop portion, and a connecting metal fitting 2 such as a sulcan is connected to the loop portion 21 so that fish caught by a fish hook can be pulled. At this time, the fishing line cushioning tool expands to absorb the impact on Harris and prevent the Harris from being cut.

Conventionally, as shown in FIGS. 4 and 5, the processing method and the shape of the loop portion 21 of the fishing line cushioning tool are as shown in FIG. 4 and FIG. The loop portion 21 is formed by abutting on the portion 22 and sandwiching the contact portion with a heating tool such as a soldering iron, heating and pressing and welding. After that, the extra length portion A shown by the hatched portion in FIG. 5 is cut, and the burr melted and leached from the welded portion 24 is removed. The loop portion 2 shown in FIGS.
1 is actually connected to the connecting fitting 2, but the connecting fitting 2 is not shown in FIGS. 4 and 5 to show the shape of the loop portion 21 and the processing method.

[0005]

However, in the above-described conventional fishing line cushioning tool, a step is formed between the welded portion of the loop portion 21 (cut surface of the extra length portion A) and the actual length portion 22 of the elastic filament 20. However, the fishing line is often caught in the step, causing a problem of being entangled. Further, when the fishing line cushioning device is pulled, the cross-sectional area changes abruptly at the step portion, which causes concentrated stress and increases the possibility of breaking at the step portion.

Further, in terms of manufacturing process, the welding work of the loop portion 21 of the elastic linear member 20 is often performed manually, and in the conventional processing method, the cutting work of the extra length portion A and the welding portion are performed. However, there is a problem that the work efficiency is poor and the productivity is low. Furthermore, when the extra length portion A is cut, the actual length portion 22 is likely to be scratched, so that many defective products are generated.

Therefore, the present invention has been made to solve such a problem, and it is an object of the present invention to provide a fishing line cushioning tool having less fishing line entanglement, excellent strength, good appearance, and high commercial value. As a first object, a second object is to provide a method for manufacturing a fishing line cushioning tool which has high productivity and suppresses the occurrence rate of defective products to a low level.

[0008]

In order to solve the above-mentioned problems, the fishing line shock absorber according to the first aspect of the present invention is a fishing line shock absorber which is interposed between a road line and Harris.

It is configured that the ring portion 3a of the connection fitting 2 is locked to.

According to the fishing line cushioning device having the above-described structure, a step like that in the prior art does not occur at the welded portion, that is, at the welded portion, the peripheral surface of the actual length portion 12 and the peripheral surface of the end portion 13 are substantially flush with each other. Since the cross-sectional area changes slowly, the trouble that the fishing line is entangled with the fishing line cushioning tool is reduced, and the stress concentration is suppressed, so that the tensile strength is improved. Furthermore, the appearance is improved and the commercial value is increased.

Further, the invention of claim 2 is a method for manufacturing a fishing line cushioning tool to be interposed between a road thread and Harris, wherein the end surface of the elastic linear member 1 is processed so as to be inclined with respect to the longitudinal direction, The end face of the elastic filament 1 is the real length portion 12 of the elastic filament 1.
Is a method for manufacturing a fishing line cushioning tool, which includes a step of forming a loop portion 11 by welding the abutting portion while being folded back so as to come into contact with.

According to the second aspect of the present invention, the end surface of the elastic linear member 1 is processed so as to be inclined with respect to the longitudinal direction, and the end surface is welded to the actual length portion 12 of the elastic linear member 1. The unwelded portion (surplus length portion A) unlike the conventional case does not occur, and the cutting work is unnecessary. Further, since the end face is provided so as to be inclined with respect to the longitudinal direction, the cross-sectional area at the tip of the elastic filamentous body 1 is reduced and heat is easily conducted, so that the molten portion is kept to a minimum, that is, the burr. This reduces the occurrence of burrs and eliminates the need for deburring work.

According to a third aspect of the present invention, in the second aspect of the invention, after the elastic filament 1 is inserted into the ring portion 3a of the connection fitting 2, the end surface of the elastic filament 1 is elastic. A fishing line shock absorber including a step of folding back so as to come into contact with the actual length part 12 of the body 1, forming a loop part 11 by welding the contact part, and locking the ring part 3a of the connection fitting 2 to the loop part 11. It is a manufacturing method of the ingredient.

According to the third aspect of the present invention, since the connecting fitting 2 is connected to the loop portion 11, it is easy to attach a tackle such as fishing line or weight when the fishing line cushioning tool is used. Further, when a thin fishing line is directly fastened to the loop portion 11 and used, the shearing force becomes large and the loop portion 11 may break. However, by providing the connecting fitting 2, the loop portion 11 can be prevented from breaking.

Is folded back and the end face is welded to the actual length portion 12 to form the loop portion 11. Further, the elastic metal filament 1 is inserted into the ring portion 3a of the connection fitting 2 and then the loop portion 11 is formed, whereby the connection fitting 2 is locked to the loop portion 11.

Next, a method of manufacturing the elastic linear member 1 having the above structure will be described with reference to FIGS.

First, the elastic filament 1 is prepared to have an appropriate length, and both end surfaces of the elastic filament 1 are cut so as to be inclined with respect to the longitudinal direction. The cutting angle θ of the end surface shown in FIG.
60 ° is preferred.

Next, the elastic filament 1 is attached to the ring portion 3 of the connection fitting 2.
After being inserted through a (not shown in FIGS. 2 and 3), the end portion 13 of the elastic filamentous body 1 is folded back, and the end face is brought into contact with the actual length portion 12 so that the loop portion 11 is formed. Ring part 3 at this time
The position a is located between the end surface of the elastic filament 1 and the contact portion between the end surface and the actual length portion 12. That is, the loop portion 11 and the ring portion 3
The connection metal fitting 2 is locked so that a becomes a continuous ring (a state in which the rings are connected). If the amount of folding back of the end portion 13 is too long, the loop portion 11 becomes large and the position of the connecting fitting 2 is not fixed, and the fishing line may get caught in the loop portion 11 and become entangled. If it passes, the welding work of the end face of the elastic filament 1 described below becomes difficult, and therefore it is folded back at an appropriate length.

Next, as shown in FIG. 2, the contact portion is pressed by the heat-generating tool 7 in the direction of the arrow. Then, the pressing portion is melted by the heat of the heat-generating tool 7, and the end surface of the elastic filamentous body 1 is welded to the outer peripheral surface of the actual length portion 12. At this time, the heating tool 7 is pressed so that the entire end face is welded. Also, the real length part 1
If welding is performed while moving the heat generating tool 7 in the lengthwise direction or the circumferential direction so that the end surface of the elastic filamentous body 1 is along the outer peripheral portion of 2, the adhesion is increased, which is more effective. Further, after welding, it is more preferable to shape while melting the periphery of the welded portion with a heating tool such as a soldering iron.

The heat-generating tool 7 is composed of a tool having a pair of opposing block-shaped holding portions, and one or both of the block-shaped holding portions generate heat.

Further, a concave groove (a groove having a cylindrical shape or a truncated cone shape) may be provided on the surface of the heat generating tool 7 facing the welded portion of the elastic filament 1. By doing so, welding can be performed while shaping the outer peripheral surface of the welded portion when pressed.

Then, the welding operation is similarly performed on the other end of the elastic portion 1 of the welding portion, and the loop portion 11 is formed, whereby the fishing line shock absorber is manufactured.

The fishing line cushion according to the present embodiment is manufactured by the above procedure. When using the fishing line cushion as shown in FIG. 1, the ring portion 3b of the lower connecting fitting 2 is used. The Harris 5 having an appropriate length is fastened to the hook 5, and the fishing hook 6 is fastened to the other end of the Harris 5. In addition, the ring portion 3b of the upper connection fitting 2
The thread is fastened to the thread through a mechanism such as Tenbin or weight.

When the fish bites on the fishing hook 6 and a sharp tension is applied to the Harris 5 due to the pulling of the fish, the fishing line cushioning tool is extended to reduce the impact on the Harris 5 and prevent the Harris 5 from being cut. It is like this.

The fishing line shock absorber according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the cross-sectional shape of the elastic filament 1 may be polygonal or elliptical instead of circular.

The elastic filament 1 may be cut into a suitable length and then the end face may be processed into an inclined shape. However, when the elastic filament 1 is cut out from a long object, it may be cut into an inclined shape. Good. Then, since both of the cut surfaces are inclined, the labor required for processing is reduced.

The shape of the connecting fitting 2 is not limited to that in the above embodiment, and may be a salkan with a snap, a salkan with a weight, or the like. Further, the connecting fittings 2 do not have to have the same shape at both ends of the elastic filamentous body 1 and need not be provided at both ends.

Further, in the welding method of the loop portion 11, it is not necessary to press while heating with the heating tool 7, for example, the welding surface is first heated and melted, and then the welding surface is applied with the pressing tool. It may be pressed and welded. In this case, the work of inserting the connecting fitting 2 and the work of melting the welding surface may be performed in tandem.

The heat-generating tool 7 is not limited to the shape of the above embodiment, but may be a soldering iron, pliers, pliers or a tool similar to them. That is,
The heat generating tool 7 may be any one capable of melting the welded portion of the fishing line cushioning tool and welding the end surface of the elastic filamentous body 1 to the outer peripheral surface of the actual length portion 12.

Further, the usage form of the fishing line cushioning tool is not limited to that shown in FIG. 1, and a plurality of fishing hooks 6 may be fastened, or a pseudo bait may be fastened instead of the fishing hooks.
