Description

  The present invention relates to a simulated bait used for fishing, and more particularly to a simulated bait made of a soft resin having flexibility.

  Generally, the artificial bait has a shape resembling a real bait and can attract interest such as predatory fish by acting like a live bait in water. There are various types of artificial bait, and the angler must select the most suitable artificial bait according to the type of fish to be fished and the environment in which the fish live.

  In particular, a simulated bait called a soft lure is mainly formed of a thermoplastic resin such as vinyl chloride and has flexibility and elasticity very similar to those of small fish to be eaten. Soft lures are widely used because they can make creature-like subtle movements in water taking advantage of their unique flexibility.

  Furthermore, the soft lure does not feel unnatural because the biting comfort is good when the fish to be prey is misunderstood as raw feed and bites. Therefore, good fishing results can be achieved. In addition, since the soft lure may be molded by injecting a soft resin into the cavity of a predetermined mold, it also has a feature that the manufacturing process is easy.

  By the way, in general, a fish moves a fin when swimming and generates a wave by scraping the surrounding water against the water flow. The conceptual diagram is shown to Fig.3 (a). Large fish that feed on small fish can catch small fish by sensing the waves generated from the small fish.

  On the other hand, in the artificial bait formed of a soft resin such as vinyl chloride, as shown in FIG. 3 (b), it only swings along the flow of the water stream because of the high flexibility of the main body. That is, the soft artificial bait can not stir the surrounding water and can not generate a wave. Moreover, such artificial bait does not have buoyancy and does not push back water, so there is no propulsive force and there is a problem that it is not possible to reproduce a swimming state like a small fish.

  On the other hand, as shown in FIG. 3C, the artificial bait formed of a hard material can stir the surrounding water during swimming and can generate a wave. However, there is a problem that the hard artificial bait feels a sense of incongruity when the fish eats it, and it immediately spits out.

  Then, in order to eliminate such a problem, the core which consists of a hard material which has a hollow part inside is formed, and the artificial bait which covered the soft resin on the surface is proposed (for example, refer to patent documents 1) ). FIG. 4 shows a cross-sectional view of the artificial bait. The simulated bait 30 comprises a hard core 32 containing the hollow portion 33 and a cover layer 31 made of a soft resin coated on the surface thereof.

According to the artificial bait 30, the covering layer 31 can give a fish-like texture, and the hard core material 32 can stir the surrounding water during swimming, so that a wave can be generated.
JP 2002-51669 A

  However, such artificial bait 30 has a problem that the number of manufacturing steps is increased as compared with the artificial bait consisting only of soft resin, and the manufacturing cost becomes high. Furthermore, since the hard core material 32 is provided inside, only the surface becomes soft, and there is a problem that when the fish bites, it feels uncomfortable and spits out.

  Then, this invention is made in view of the said subject, and when the fish bites, it has the texture which does not feel discomfort, and provides the simulated bait which can produce a wave at the time of swimming.

  In order to solve the above problems, the artificial bait according to the present invention is characterized in that the main body is made of a soft resin and a hollow portion is provided inside the main body.

  According to the present invention, since the body of the artificial bait is formed of the soft resin, it has the texture of real fish-like flexibility and elasticity. As a result, the bite of the artificial bait is improved, biting of the fish is improved, and once it is bitten, good fishing results can be obtained without releasing it.

  In addition, although the artificial bait formed of a soft resin alone does not have buoyancy or can not expect large buoyancy, it can have buoyancy by providing a hollow portion inside the main body of the artificial bait.

  The artificial bait having the above-mentioned structure has a load of 2.55 N to 5.88 N required to make a metal probe having a conical shape with a radius of 7 mm and a length of 18 mm at its tip with respect to the soft resin. It is characterized by having the surface hardness which is. Furthermore, it is preferable that the said load is 2.94N-3.82N.

  In the present invention, it is preferable that the artificial bait has flexibility and elasticity like a live fish, and also generates waves generated by the fins scraping water during swimming. For this purpose, the soft resin forming the body needs to have a certain degree of hardness without losing the flexibility and elasticity of the material. For that purpose, it is preferable to have the above-mentioned surface hardness which hardness is larger than a raw fish and smaller than a hard resin.

  Then, methacrylic resin is mentioned as a soft resin which has optimal surface hardness. Methacrylic resins have high transparency and mechanically strong properties. Further, since it can be colored, it can be applied vividly.

  That is, the artificial bait according to the present invention has the main body made of soft resin and is provided with the hollow portion inside, so that it has the flexibility and elasticity like a real fish while having buoyancy. it can. Such artificial bait can artificially reveal the situation in which aquatic organisms such as small fish are swimming at the time of reeling. Furthermore, even if the fish to be eaten bites, it is possible to obtain a good bite with a good bite feeling and without releasing the bite artificial bait.

  The main body of the artificial bait is formed of a soft resin which has a surface hardness larger than that of a raw fish and smaller than that of a hard resin. Therefore, while having flexibility and elasticity, it can generate waves generated when swimming fish. , Can increase the fish collection effect.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view of a simulated bait according to an embodiment of the present invention. The artificial bait 10 includes a hollow portion 12, a main body 11 including the hollow portion 12, and a core 13 embedded along the tail portion from the jaw portion of the bottom surface of the main body 11. Further, the main body 11 is provided with a lip which is a water flow resistance plate in a jaw portion, has an appearance of a fish shape, and is formed of a soft resin.

  In the center core 13, a fishing line locking portion 13a, an abdominal needle hooking portion 13b and a tail needle hooking portion 13c, which are projected outward from the jaws, abdomen and tail of the main body 11, respectively, It is formed. A fishing line drawn from a fishing rod is attached to the fishing line locking portion 13a. The hooks are attached to the abdominal hook 13b and the tail hook 13c, respectively.

Next, an example of a molding technique of the artificial bait 10 will be described.
The mold forming the artificial bait 10 is composed of a pair of left and right molds which are divided so as to be cut along the center line of the head to the tail. Then, a soft resin is injected into the cavity of each mold to form a half-split member. In addition, the hollow for embedding the core 13 in the lower surface of one half member is formed, and the core 13 is accommodated in this hollow.

  Subsequently, the bonding surfaces of the half members are brought into contact with each other for bonding. As an adhesive used at this time, an elastic adhesive is preferable, but it is not limited thereto as long as it can be adhered. In addition, bonding may be performed by ultrasonic welding in which vibration is directly applied to the bonding surfaces of the half members, and heat melting or pressure bonding is performed.

  Further, as a technique for integrally producing the main body 11 having the hollow portion 12, there is also a molding method called die slide injection method (hereinafter also referred to as DSI method).

The DSI method is a method of welding two or more divided compacts in a mold.
First, in a state in which the divided molded body is slid, half of the molded body is molded at one time by primary injection. Then, the mold is opened and slid to abut each other to close the mold. Then, resin is filled in the joint portion of the two molded bodies by secondary injection, and the respective molded bodies are welded. Thereby, a compact having a hollow portion can be produced.

  According to this DSI method, the steps of adhesion and welding which have been performed to join the divided molded bodies are unnecessary, and the number of joining steps can be reduced. Moreover, the bonding strength can be improved, and excellent productivity can be obtained.

  As described above, according to the artificial bait 10 according to the present embodiment, the main body 11 is formed of a soft resin, so that it can have flexibility and elasticity like a real fish, and it is unnatural for a prey fish Softness can be revealed. Further, by providing the hollow portion 12 inside the main body 11, it is possible to have buoyancy, shorten the manufacturing process, and realize the reduction of the manufacturing cost.

  In the above embodiment, the main body 11 of the artificial bait 10 may be formed of a transparent soft resin, and a reflective sheet whose color changes depending on the angle to be observed may be attached to the cross section of the main body 11. Thereby, when the simulated bait 10 is made to act in water, the light transmitted through the transparent main body 11 is reflected by the reflective sheet, and the color of the reflected light changes in accordance with the operation of the simulated bait 10. As a result, the simulated bait 10 appears as if a real fish is swimming, and a large fish collecting effect can be obtained.

  In addition, a balancer (gravity center weight) may be incorporated in the hollow portion 12, whereby the flight distance of the simulated bait 10 can be extended, and rapid diving and the like can be operated at will. Furthermore, the weight of the balancer can be adjusted in accordance with the type and the habitat of the fish to be fished, and the artificial bait 10 capable of aiming at a desired depth can also be provided.

  Also, in the above embodiment, the artificial bait 10 is formed to resemble the shape of a small fish, but is not limited thereto, and fish of prey such as shrimps, pirates, salmon or aquatic organisms are used as bait The shape of various aquatic organisms may be imitated.

  Furthermore, in the above embodiment, an umbrella needle, which is a fishing needle not provided with a return, may be attached to the tail needle hook portion 13c of the simulated bait 10 and used for squid fishing.

  Hereinafter, the present invention will be specifically described based on examples, but the present invention is not limited to the following examples.

  In the present example, using a physical property measuring device, the surface hardness of small fishes which various soft resins and fish were eating was examined. In FIG. 2, the schematic of physical-property measurement experiment which measures surface hardness is shown. From FIG. 2, FIG. 2 (a) shows a state before measurement, and FIG. 2 (b) shows a state during measurement.

  In the present example, a rheometer CR-200D (manufactured by Sun Scientific Co., Ltd.) was used as a physical property measuring device. In the physical property measuring device, the probe 21 for measuring the surface hardness of the measuring material 23 is made of metal, and the tip of the probe 21 has a conical shape with a radius of 7 mm and a length of 18 mm. Then, as a measurement condition, the approach distance (a) of the probe 21 was set to 0.1 mm or 0.5 mm, and the approach speed was set to 100 mm / s.

Next, the method of measuring the surface hardness will be described.
First, the measuring material 23 is placed on the measuring stand 22 of the physical property measuring instrument, and the measurement is started. Then, as shown in FIG. 2A, the measurement stand 22 moves in the direction of the probe 21 at the entry speed. Then, as shown in FIG. 2B, the probe 21 enters a predetermined approach distance (a) into the measurement material 23, and the surface hardness (N) at this time is measured.

  From Table 1 above, Examples 1 to 10 are materials of various soft resins. Parapet (registered trademark) of Examples 1 to 6 is a molding material of methacrylic resin (PMMA). In addition, Parapet (registered trademark) of Example 2 is the one in which the surface of the material is coated. Parapet (registered trademark) of Example 3 is a product having a particularly flexible property and a property that does not lose flexibility even in a low temperature environment (0 ° C. or less). Parapet (registered trademark) of Example 4 is foam-molded. The Parapet (registered trademark) of Example 5 has a hollow portion inside. The Parapet (registered trademark) of Example 6 has the hollow portion and a cloth wound on the surface of the material.

  Lavaron (registered trademark) in Examples 7 and 8 is a molding material of a styrenic thermoplastic elastomer. Lavaron (registered trademark) of Example 8 is foam-molded. Promalloy (registered trademark) of Example 9 is a molding material of polyester-based thermoplastic elastomer. Cosmogel (registered trademark) of Example 10 is a new material based on polyethylene.

  The vinyl chloride resin of Comparative Example 1 is a material used for a normal soft lure. ABS (acrylonitrile-butadiene-styrene) resin of Comparative Example 2 is a material used for a normal hard resin luer. The lead of Comparative Example 3 is a material used for a jig (a type in which the lure itself has no action). The reference examples 1 to 7 are small fish that large fish eats. In the present embodiment, these fish were placed on the measurement stand 22 in a living state and measured.

  The load (N) required for the probe 21 to enter for a predetermined distance was measured for each of the above-described materials and raw fish. First, the load (N) when the approach distance was 0.1 mm was measured five times, and the average value was determined. Next, the load (N) when the approach distance was 0.5 mm was measured five times, and the average value was determined.

  From the results of Table 1, the load (N) of the small fish was 0.39 N to 0.59 N when the approach distance was 0.1 mm. Moreover, when the approach distance was 0.5 mm, it was 0.49N-1.28N. It was found that Lavalon (registered trademark), Primalloy (registered trademark), Cosmogel (registered trademark) and the vinyl chloride resin of Comparative Example 1 of Examples 7 to 10 were the materials having the same surface hardness as this small fish. .

  However, although the material having the same surface hardness as the above-mentioned small fish has high flexibility, it does not perform swimming even when subjected to water flow and only shakes it, and there is no power to push back the water. That is, as shown in FIG. 3 (b), it was found that a small fish can not generate a wave generated during swimming.

  Therefore, as a material having high flexibility and generating waves during swimming, it is considered appropriate that the surface hardness is larger than that of small fish and smaller than that of hard resin. When the approach distance was 0.5 mm, the maximum value of the stilts with the largest surface hardness of the raw fish was 1.28 N. Moreover, the minimum value of the surface hardness of the ABS resin which is a hard resin was 11.96N. From this result, it is considered that a soft resin having a surface hardness in the range of 1.28 N to 11.96 N is preferable.

  Parapet (trademark) is mentioned as a material which fulfills such conditions. Parapet (registered trademark) had a load of 2.55 N to 5.88 N when the entry distance was 0.5 mm. This value is larger than the maximum value (1.28 N) of the plum tree mentioned above and smaller than the minimum value (11.96 N) of the ABS resin. Furthermore, it has been found that the simulated bait formed with Parapet (registered trademark) can generate a wave because it can stir water like a small fish during retrieval.

  Moreover, since it can have buoyancy by providing a hollow part in the inside of the pseudo | simulation bait shape | molded by Parapet (trademark), it turned out that the most preferable load is 2.94N-3.82N.

  As described above, according to this embodiment, it is preferable to use a soft resin having a load of 2.55 N to 5.88 N required to make the probe enter 0.5 mm, and a soft load having a load of 2.94 N to 3.82 N It has been found to be more preferable to use a resin. If it is the soft resin which exists in the range of the value of the above-mentioned load, it may not be restricted to Parapet (registered trademark), and anything may be sufficient. Of course, methacrylic resin which is a molding material of Parapet (registered trademark) may be used.

  As a feature of Parapet (registered trademark), it can be mentioned that it is a good material that is excellent in flexibility and elasticity and has transparency, which is an excellent feature of common methacrylic resin, and weather resistance. In addition, since the strength is high and the transparency is high and it is easy to paint, it is possible to apply a bright paint resembling a living fish.

  It is sectional drawing of the artificial bait by Embodiment 1 of this invention.   It is the schematic for demonstrating the physical-property measurement experiment by a present Example. FIG. 2 (a) shows a schematic view before measurement, and FIG. 2 (b) shows a schematic view during measurement.   It is a figure for demonstrating the state which the small fish and the artificial bait are swimming in water. 3 (a) shows a small fish, FIG. 3 (b) shows a simulated bait formed of a soft resin such as vinyl chloride, and FIG. 3 (c) shows a swimming state of a simulated bait formed of a hard resin.   It is sectional drawing of the conventional simulated bait.
