Description

  The present invention relates to a pseudo bait used for fishing. Specifically, the present invention relates to a simulated bait having a high specific gravity head.

  Carp fishing is carried out using a pseudo bait called cabra. The simulated bait has a metal head, a rubber tie and skirt, and a hook. The head is colored by the paint layer. This simulated bait is submerged in the seabed with the fishing line tied. When the fishing line is pulled and the pseudo bait rises in the seawater, the flushing of the head appeals to the kite. Furthermore, the tie and the skirt swing under the water pressure. By this swinging, the persimmon misunderstands the pseudo food as a live food and bites into the pseudo food. The hook is stuck in the kite and the kite is picked up. This simulated bait is also referred to as “tylababa”. A pseudo bait suitable for carp fishing is described in Japanese Patent Application Laid-Open No. 2008-212146.

JP 2008-212146 A

  The range with the heel is called Tana. When the angler throws the pseudo bait into the sea, the pseudo bait sinks in the water. After the pseudo bait has arrived at Tana, the fishing line is drawn, so that the carp eats the pseudo bait. A pseudo bait that takes a short time to reach Tana after being put into the sea is advantageous in terms of fishing results. Anglers want a fake bait with a fast sinking speed.

  The subsidized simulated food may collide with rocks on the seabed. This collision damages the head. Due to the damage, a part of the coating layer of the head may be peeled off. When the collision is repeated, the color of the head gradually changes. The change in color damages the fishing results.

  An object of the present invention is to provide a pseudo bait that has a high sedimentation speed and is unlikely to cause head damage.

  The pseudo bait head according to the present invention includes a main part and a weight having a density larger than the density of the main part. This weight has an embedded part wrapped around the main part and an exposed part not wrapped around the main part.

  Preferably, the ratio (D2 / D1) of the density D2 of the weight to the density D1 of the main part is 1.4 or more.

Preferably, the density of the main part is 10.0 g / cm ³ or more, and the density of the weight is 18.0 g / cm ³ or more.

  Preferably, the material of the main part is lead or a lead alloy, and the material of the weight is tungsten or a tungsten alloy.

  Preferably, the head further includes a wire. This wire penetrates the main part and the weight.

  Preferably, the surface of the main part is colored and the surface of the exposed part is not colored.

  Preferably, in the cross section that passes through the center of gravity of the head and extends in the vertical direction and the front-rear direction, the area center of gravity of the weight is located forward and below the area center of gravity of the head.

  The simulated bait according to the present invention includes a head and a rocking body attached to the head. The head has a main part and a weight having a density larger than the density of the main part. The weight has an embedded part wrapped around the main part and an exposed part not wrapped around the main part.

The method of manufacturing the simulated bait head according to the present invention is as follows.
Passing the wire through the weight so that the end of the wire is exposed from the weight,
Inserting the weight and wire into a mold;
Injecting molten metal into the mold and filling the mold cavity with the molten metal such that the ends of the wires are exposed from the molten metal;
Cooling and solidifying the molten metal to form a main part,
And the process which deletes the part exposed from the said main part among the said wires is included.

  Since the simulated bait head according to the present invention includes a weight having a large density, the head as a whole has a large density. The settling speed of the pseudo bait having this head is fast. Since the weight has an exposed portion, in this head, the main portion does not frequently collide with the seabed. In this head, the main part is hardly damaged. A large fishing result can be obtained by this simulated bait.

FIG. 2 is an enlarged front view showing the head of the pseudo bait shown in FIG. FIG. 3 is a left side view showing the head of FIG. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. FIG. 5 is an explanatory view showing a state of manufacturing the head of FIG. FIG. 6 is an explanatory view showing a state of manufacturing the head of FIG. FIG. 7 is a front view showing the use of the pseudo food of FIG.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  The simulated bait 2 shown in FIG. 1 is called a turnip. The simulated bait 2 has a head 4, a plug 6, a hook unit 8, a tie 10 and a skirt 12. The tie 10 is a rocking body. The skirt 12 is also a rocking body. The simulated bait 2 may have a rocking body other than the tie 10 and the skirt 12.

  2 is an enlarged front view showing the head 4, FIG. 3 is a left side view showing the head 4, and FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. In FIG. 2, the left side is the front side of the head 4, and the right side is the back side of the head 4.

  The head 4 has a main part 14, a weight 16 and a wire 18. The material of the weight 16 is different from the material of the main portion 14. The density of the weight 16 is greater than the density of the main portion 14. A typical material of the main portion 14 is lead or a lead alloy. A typical material of the weight 16 is tungsten or a tungsten alloy.

  The main portion 14 has a hole 20. The hole 20 is located above the main portion 14 and extends in the front-rear direction. The hole 20 passes through the main portion 14. A pipe 22 is fitted in the hole 20. The pipe 22 is joined to the hole 20 with an adhesive. The pipe 22 has a straight portion 24 and a socket 26 located behind the straight portion 24. The inner diameter of the socket 26 gradually increases toward the rear.

  The entire surface of the main portion 14 is covered with a coating layer. The head 4 is colored by this coating layer. Coloring appeals to the eyelids. The surface of the main portion 14 may be partially covered with a coating layer.

  A fishing line 28 (see FIG. 1) is passed through the pipe 22. The inner diameter of the pipe 22 is sufficiently larger than the outer diameter of the fishing line 28. Accordingly, the head 4 can easily move relative to the fishing line 28.

  The weight 16 is located at the front and the lower side in the head 4. The weight 16 has an embedded part 30 and an exposed part 32. The buried portion 30 is wrapped around the main portion 14. The exposed portion 32 is not wrapped around the main portion 14. The exposed portion 32 is located on the front side and the lower side of the embedded portion 30. The exposed part 32 does not have a coating layer.

  The wire 18 passes through the main portion 14 and the weight 16. The movement of the weight 16 relative to the main portion 14 is prevented by the wire 18. Examples of the material of the wire 18 include steel and stainless steel.

  Although not shown, the plug 6 is connected to the fishing line 28. The plug 6 is made of a hard synthetic resin. As shown in FIG. 1, the front portion of the plug 6 enters the socket 26 (see FIG. 4). The plug 6 is not joined to the socket 26. Therefore, the angler can remove the plug 6 from the socket 26 and move the plug 6 backward.

  The hook unit 8 includes a silicon 34 and two hooks 36. One hook 36 is fastened to one end of the silicon 34, and the other hook 36 is fastened to the other end of the silicon 34. A typical material of silicon 34 is aramid fiber (registered trademark “Kevlar”). The hook 36 is made of metal. The hook unit 8 is connected to the fishing line 28 via a ring or the like (not shown).

  The tie 10 is strip-shaped. The vicinity of the center of the tie 10 is hung on the plug 6. The tie 10 is made of a soft material. When subjected to water pressure, the tie 10 swings and appeals to the presence of the pseudo food 2. Typically, the tie 10 consists of a rubber composition. The tie 10 may be formed from a soft synthetic resin. The tie 10 may not be provided.

  The skirt 12 is composed of a large number of yarns 38. This thread 38 is long. The vicinity of the center of the thread 38 is hung on the plug 6. The thread 38 is made of a soft material. When subjected to water pressure, the thread 38 swings and appeals to the presence of the pseudo food 2. Typically, the thread 38 is made of a rubber composition. The thread 38 may be formed from a soft synthetic resin. The thread 38 may not be provided.

  Hereinafter, a method for manufacturing the head 4 will be described. First, the weight 16 is formed. For forming the weight 16, a sintering method, a casting method, or the like can be employed. Next, as shown in FIG. 5, the wire 18 is passed through the weight 16. The wire 18 is fixed to the weight 16 with an adhesive. Both ends 40 and 42 of the wire 18 are exposed from the weight 16.

  The weight 16 and the wire 18 are inserted into the mold. Molten metal is poured into this mold. A typical metal is the aforementioned lead or lead alloy. The melting point of this metal is low. The temperature of the molten metal is lower than the melting point of the weight 16 and lower than the melting point of the wire 18. The mold cavity is filled with molten metal. The molten metal surrounds the embedded portion 30. The molten metal covers a part of the wire 18. The metal is cooled and solidified to form the main portion 14. The buried portion 30 is cast around the main portion 14. A part of the wire 18 is cast around the main portion 14. As shown in FIG. 6, both ends 40 and 42 of the wire 18 are exposed from the main portion 14. The main portion 14 is coated with a paint and dried. Finally, the vicinity of the end of the wire 18 is cut off to complete the head 4.

  When this simulated food 2 is thrown into the sea, the density of the simulated food 2 is greater than the density of seawater, and thus sinks. As described above, the weight 16 is positioned in the head 4 at the front side and the lower side. Therefore, the center of gravity of the head 4 is biased forward and downward relative to the area center of gravity in the cross section shown in FIG. The head 4 sinks in a posture in which the exposed portion 32 is positioned below. Since the density of the weight 16 is large, the sedimentation speed is fast.

  After the pseudo bait 2 reaches a predetermined depth, the fishing line 28 is wound and the pseudo bait 2 rises. At this time, the tie 10 and the skirt 12 swing. By this swinging, the persimmon misunderstands the pseudo bait 2 and eats the pseudo bait 2. The hook 36 pierces the kite and the kite is picked up.

  Since the density of the weight 16 is large, the head 4 has a sufficient mass even if the volume thereof is reduced. A wrinkle tends to bite into the head 4 having a small volume. The head 4 can contribute to fishing results in a condition where the carp eats.

  Even when the fishing line 28 is pulled in the horizontal direction or obliquely upward, the center of gravity of the head 4 is appropriate, so that the pseudo bait 2 is not easily lifted. Therefore, fishing can be continued while keeping a predetermined range.

  As shown in FIG. 7, the simulated food 2 that has reached the seabed may collide with the rock 44. Since the strength of the main portion 14 is low, the main portion 14 may be plastically deformed by an impact at the time of collision. Since the wire 18 penetrates the weight 16 and the main portion 14 as described above, even if the main portion 14 is deformed, the position of the weight 16 does not vary greatly. In other words, the position of the center of gravity of the head 4 does not vary greatly.

  Since the center of gravity of the head 4 is biased, the frequency of the exposed portion 32 colliding with the rock 44 is high when the pseudo bait 2 reaches the bottom. Since the exposed portion 32 does not have a paint layer, the paint layer does not peel off even by a collision. Since the strength of the exposed portion 32 is high, the exposed portion 32 is hardly damaged even by a collision. Although the main part 14 may collide with the rock 44, since the main part 14 is soft, peeling of the coating layer due to the collision hardly occurs. In this pseudo bait 2, the color change is less likely to occur when used repeatedly.

  Since the center of gravity of the head 4 is biased, the pseudo bait 2 after bottoming maintains a posture in which the weight 16 is on the lower side and the tie 10 and the skirt 12 are on the upper side. In the pseudo food 2 in this posture, the tie 10 and the skirt 12 appeal the presence of the pseudo food 2 to the bag.

  The cross section shown in FIG. 4 is a cross section when the head 4 is cut by a plane that passes through the center of gravity of the head 4 and extends in the vertical direction and the front-rear direction. In FIG. 4, what is indicated by reference sign P1 is the area centroid of the head 4 in this section, and what is indicated by reference sign P2 is the centroid of area of the weight 16 in this section. The area centroid P2 is located in front of and below the area centroid P1. Thereby, an appropriate center of gravity of the head 4 is achieved.

  In FIG. 4, what is indicated by a symbol L1 is a vertical distance between the area centroid P1 and the area centroid P2. From the viewpoint of an appropriate center of gravity of the head 4, the distance L1 is preferably 1.0 mm or more, and particularly preferably 2.0 mm or more. The distance L1 is preferably 20 mm or less.

  In FIG. 4, what is indicated by a symbol L2 is the distance in the front-rear direction between the area centroid P1 and the area centroid P2. From the viewpoint of an appropriate center of gravity of the head 4, the distance L2 is preferably 1.0 mm or more, and particularly preferably 2.0 mm or more. The distance L1 is preferably 20 mm or less.

  From the viewpoint of an appropriate center of gravity position of the head 4, the ratio (D2 / D1) of the density D2 of the weight 16 to the density D1 of the main portion 14 is preferably 1.4 or more, more preferably 1.5 or more, and 1.6. The above is particularly preferable. The ratio (D2 / D1) is preferably 5.0 or less.

From the viewpoint that the head 4 can have a large density, the density D1 of the main portion 14 is preferably 10.0 g / cm ³ or more, and particularly preferably 11.0 g / cm ³ or more.

From the viewpoint that the head 4 can have a large density, the density D2 of the weight is preferably 18.0 g / cm ³ or more, and particularly preferably 19.0 g / cm ³ or more.

  The weight 16 may be arranged so that the area gravity center P2 (see FIG. 4) is located directly below the area gravity center P1 from the viewpoint of adjusting the posture of the pseudo bait 2 after landing. In this case, the distance L2 is zero.

  The weight 16 may be arranged so that the area gravity center P2 (see FIG. 4) is located behind the area gravity center P1 from the viewpoint of adjusting the posture of the pseudo bait 2 after landing. In this case, the distance L2 is a negative value.

  The simulated bait according to the present invention is suitable for fishing targeting not only carp but also various fishes such as sword fish, flounder, ayame and maggot. The head according to the present invention can also be used for sedimentation of other rocking bodies and live food.
