Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fishing lure and a method for producing the same.

[0002]

2. Description of the Related Art Generally, lures for fishing are roughly divided into soft lures and hard lures. Some soft lures are called worms that mimic the food of fish such as earthworms, crayfish, and small fish. Conventional worms are formed by adding a plasticizer such as phthalic acid ester to PVC (polyvinyl chloride), which is a kind of synthetic resin, or by mixing a salt with PVC.

[0003]

However, since the worm formed by mixing PVC alone or PVC with a salt is light in weight, the flight distance during casting is not increased, and the sinking speed in water is low. Become. Also,
If the mixing amount of salt is large, the strength is reduced and it is easy to tear,
There is a problem that the salt is dissolved during use and the weight is further reduced.

In order to compensate for the weight of the worm, it is common practice to attach a separate weight to the worm, thereby extending the flight distance and increasing the sinking speed during casting. However, if the casting is performed with a separate weight attached to the worm, the weight balance is lost, so it is difficult for a beginner to perform accurate casting.

[0005] Further, when a worm is formed by mixing a salt with PVC, there is another problem that a fishing hook pierced by the worm is rusted.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fishing lure which flies well during casting and sinks quickly in water, and which does not promote the rust of the hook, and a lure therefor. It is to provide a manufacturing method.

[0007]

In order to solve the above-mentioned problems, a fishing lure according to the present invention has a substrate formed of a synthetic resin material having flexibility, and a base material enclosed in the substrate. And metal powder.

[0008] In a method of manufacturing a fishing lure according to the present invention, the first base portion is formed of a flexible synthetic resin material, and a metal powder is kneaded into the flexible synthetic resin material. Placing an inner body of the body on the first base portion;
A second base portion made of a synthetic resin material having flexibility is formed on the inner sealing body by covering and covering the inner sealing body to form a predetermined shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a worm 1 as a fishing lure according to a first embodiment of the present invention. The worm 1 is composed of a base material 2 formed of a synthetic resin material having flexibility (such as PVC) and a metal powder 4 enclosed in a dispersed state (mixed state) in the base material 2. Molded (casting etc.) to imitate the shape.

The material of the metal powder 4 is preferably a material having a specific gravity of 7 or more and 20 or less, such as tungsten, iron, and lead. The size of the metal powder 4 is about 2 μm to 5 μm.
Desirably, it is about 0 μm. Furthermore, metal powder 4
Is preferably about 5 to 50% by weight. By changing the weight ratio, the flight distance and sinking speed during casting can be adjusted. Further, the shape of the worm 1 does not need to be a small fish, and can take any other shape. Also, considering the weight balance at the time of sinking in water, it is preferable that the center of gravity is concentrated downward.

In the worm 1 having such a structure, the metal powder 4 having a high specific gravity is enclosed in a dispersed state in the base material 2.
The casting distance increases, and the sinking speed in water increases. Therefore, it is not necessary to attach a separate weight to the worm 1 as in the related art, and the weight balance is improved.
Accurate casting becomes possible. In addition, metal powder 4
Since the worm 1 is dispersed in the base material 2, the fishing hook can be smoothly pierced (penetrated) with the worm 1. Further, since the powder mixed with the base material 2 is a metal and not a salt, the powder is dissolved in water to reduce the weight,
There is no defect such as piercing fish hook rusting due to powder. Instead of dispersing the metal powder 4 in the substrate 2, a plate made of the metal powder may be partially enclosed in the substrate 2.

FIGS. 2 and 3 show a worm 1A as a fishing lure according to a second embodiment of the present invention. The worm 1A is obtained by adding a plasticizer such as phthalic acid ester to a flexible synthetic resin material (such as PVC) for 40 to 5 minutes.
Consisting of a base material 2 formed by adding about 0% and curing, and a rod-like inner seal body 6 partially enclosed in the base material 2 separately, for example, imitating the shape of a small fish. Molded (casting etc.). The inner sealing body 6 is formed by kneading a metal powder into a synthetic resin material having flexibility (such as PVC), and the material of the metal powder is tungsten,
It is desirable that the specific gravity of iron, lead, etc. be 7 or more and 20 or less.
Further, the size of the metal powder is desirably about 2 μm to about 50 μm. The smaller the size of the metal powder,
It is well compatible with synthetic resins, and is less likely to break even when a fishing hook penetrates. Further, the weight ratio of the metal powder is preferably about 5 to 50%. By changing the weight ratio, the flight distance and sinking speed during casting can be adjusted. The shape of the worm 1A does not need to be a small fish, and can take any other shape.
Also, considering the weight balance at the time of sinking in water, it is preferable that the center of gravity is concentrated downward (it is desirable to dispose the inner sealing body 6 below the base material 2).

The worm 1A having such a structure is formed by partially enclosing the inner sealing body 6 in which the metal powder having a high specific gravity is kneaded in the base material 2, so that the position of the center of gravity can be easily adjusted. It can be adjusted and does not greatly affect the color of the substrate 2. Also, since the casting distance is increased and the sinking speed in water is also increased, there is no need to attach a separate weight to the worm 1A as in the past, and the weight balance is improved and accurate casting is possible. become. Further, since the powder kneaded in the inner sealing body 6 is a metal and not a salt, there is no problem that the powder dissolves in water to reduce the weight, or the stuck fishing hook rusts due to the powder. .

Further, since the metal powder is kneaded into the synthetic resin material in the inner sealing body 6, the fishing hook can be smoothly pierced (penetrated) with the worm 1A. In general, if the metal powder is simply mixed in the base material 2 in a dispersed state, a portion where only the metal powder is concentrated tends to be generated, and in this concentrated portion, the density of the synthetic resin serving as a bridge is inferior. There is a problem that the worm is easily torn when pierced. On the other hand, in the present embodiment, the inner package 6 formed by kneading the metal powder into the synthetic resin material (the metal powder is adapted to the synthetic resin and the density thereof is
Is uniformly enclosed throughout the base material 2 (the inner body 6 is covered with the base material 2), so that even if the fishing hook penetrates the inner body 6, the worm But not easily damaged.

Also, generally, the metal powder is directly used as the substrate 2
When mixed in a dispersed state simply, due to gravity and specific gravity,
The metal powder may settle down (the worm surface). As a result, the blackish color unique to the metal powder is exposed on the worm surface, which may obstruct the original surface color of the worm body. However, as in the present embodiment, if the inner package 6 formed by kneading the metal powder is separately formed and sealed in the base material 2, the metal powder is exposed on the worm surface. No problem occurs with the surface color of the worm body.

In general, the metal powder is directly used as the base material 2.
If they are simply mixed in a dispersed state, the distribution of the metal powder in the base material 2 may vary. In particular, when a high specific gravity metal is mixed into a small worm, there is a possibility that the balance of the worm may be lost due to subtle variations, and there is a possibility that the worm does not swim correctly in the water or rotates in the air during casting. On the other hand, if the inner sealing body 6 in which the metal powder is kneaded is formed as a separate body as in the present embodiment, the dispersion of the metal powder is less likely to occur and proper dispersion can be achieved. It is unlikely to occur.

In the present embodiment, the metal powder is
Since it is very fine, about 2 μm to 50 μm, it is easy to fit into the synthetic resin when it is kneaded, and even if the fishing hook penetrates the inner sealing body 6, it is unlikely to be damaged.

An example of a method for producing the worm 1A shown in FIG. 2 (a casting method using a mold) is shown in FIGS.

When forming the worm 1A, first, as shown in FIG. 4, a base material 2a which is a part of the base material 2 is poured into a mold 10. Next, as shown in FIG. 5, the inner sealing body 6 formed separately is placed on the base material 2a. Subsequently, as shown in FIG. 6, the base material 2a is again placed on the inner sealing body 6 to cover it, and this is
The worm 1A is obtained by molding into a desired shape as shown in FIG.

FIG. 8 shows a worm 1B as a fishing lure according to a third embodiment of the present invention. The worm 1B has a separate inner sealing body 6A, similar to the second embodiment.
6B are divided and arranged in the longitudinal direction of the base material 2 in the same manner as in the second embodiment while being spaced apart from each other by a predetermined distance, and the regions into which the fishing hook 50 can be inserted are defined as the inner sealing bodies 6A and 6B. Secured between each other.

As in the case of the second embodiment, if a configuration is adopted in which the inner package formed by kneading the metal powder is formed as a separate body and this is encapsulated in the base material, as in the present embodiment, In addition, it is possible to divide and arrange the inner sealing bodies 6A and 6B while avoiding the portion where the fishing hook 50 is inserted. FIG. 9 shows another configuration in which the inner sealing bodies 6A and 6B are divided and arranged. In this configuration,
For example, a first inner seal 6C imitating a fish eye and a second inner seal 6D imitating a fish gill are separately arranged in the base material 2. That is, an area where the tip curved portion of the fishing hook 50 can be inserted is secured between the inner sealing bodies 6C and 6D.
In particular, in the present embodiment, the second inner body 6D imitating
Is curved so as to substantially conform to the shape of the distal end curved portion 50a of the fishing hook 50, and the insertion region of the fishing hook 50 can be formed in the base material 2 without waste.

Further, as a method of disposing the inner sealing body in the base material 2 while avoiding the portion where the fishing hook 50 is inserted, the inner sealing body can be realized without dividing and arranging a plurality of inner sealing bodies as in the third embodiment. it can. Such an implementation is shown in FIG. In FIG. 10, the same components as those in FIGS. 1 to 9 are denoted by the same reference numerals and description thereof will be omitted.

In the configuration shown in FIG.
Has one end formed in a forked shape. That is,
On one end side of the inner sealing body 6, a first one-side extending part 6a and a second one-side extending part 6b extending in the longitudinal direction of the inner sealing body 6 are formed. 2 one-sided extension 6b
Between them, a region where the fishing hook 50, particularly the bent portion 50b of the fishing hook 50, can be inserted is secured.
