Description

[Technical field]

[0001] The present invention relates to a buoyancy adjuster for an artificial bait that is attached to an artificial bait used in fishing, and is particularly characterized by its attachment structure to the artificial bait. [Background technology]

[0002] Conventionally, as an artificial bait for squid, shrimp, fish, etc., as shown in, for example, cited document 1, an artificial bait having an artificial bait body and a hook part has been generally used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3067711 Summary of the Invention [Problem to be solved by the invention]

[0004] Even if the buoyancy of the artificial bait described above is adjusted, it may not be in a substantially horizontal state in the sea or on the sea surface, but may be in a substantially vertical or oblique state due to the weight of the bottom end, etc. Since the squid, shrimp, and fish bait that the artificial bait imitates are often in a substantially horizontal state, the artificial bait's imitation of the bait is reduced when it is not in a substantially horizontal state, which may affect the catch of the squid, shrimp, fish, etc.

[0005] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a buoyancy adjuster for an artificial bait that can be easily attached to the artificial bait and can keep the artificial bait in a substantially horizontal position. [Means for solving the problem]

[0006] (1) In order to solve the above problems, the buoyancy adjustment unit for artificial bait according to the present invention is detachably attached to an artificial bait which comprises an artificial bait body and a needle part having a plurality of needles attached to an end of the artificial bait body. The buoyancy adjustment unit for artificial bait has an internal space, a body in which a buoyant body is fitted, a first attachment part protruding from a predetermined position on a side of the body and having a through hole for inserting a first needle which is one of the plurality of needles, and a second attachment part protruding from a position on the side of the body substantially opposite to the first attachment part and having a through hole for inserting a second needle which is different from the first needle of the plurality of needles.

[0007] According to the above configuration, the buoyancy adjustment unit for artificial bait can be attached to the artificial bait simply by inserting the first needle of the needle part into the through-hole of the first attachment part and the second needle of the needle part into the through-hole of the second attachment part, and the buoyancy adjustment unit for artificial bait can be easily attached to the end of the artificial bait. This makes it possible to impart buoyancy to the end of the artificial bait by the buoyant body fitted into the main body, and allows the artificial bait to be in an approximately horizontal position even if the artificial bait is formed so that it cannot assume an approximately horizontal position in water.

[0008] (2) The main body may be bowl-shaped, and the first mounting portion and the second mounting portion may protrude from an upper end of a side portion of the main body and be formed integrally with the main body.

[0009] According to the above configuration, the main body, the first attachment part, and the second attachment part are integrally molded, so that the buoyancy adjustment unit for artificial bait can be manufactured easily. Also, since the main body is bowl-shaped, when molding with a metal mold, it can be easily removed from the metal mold, so that the buoyancy adjustment unit for artificial bait can be manufactured easily.

[0010] (3) The main body, the first mounting portion, and the second mounting portion may be made of an elastically deformable soft material.

[0011] According to the above configuration, the first attachment part and the second attachment part can be elastically deformed to insert the needle of the needle part of the artificial bait into the through hole, which makes attachment to the artificial bait easier. Also, since the main body, the first attachment part, and the second attachment part are deformable, the applicable range of dimensions of the artificial bait to be attached is wider.

[0012] (4) The main body may contain a phosphorescent material.

[0013] According to the above configuration, natural light is stored in the phosphorescent material of the main body, and when it is dark at night, etc., it emits phosphorescence by emitting light. This allows squid, shrimp, fish, etc. to mistake the artificial bait to which the artificial bait buoyancy adjuster is attached for a living creature, resulting in a fish-attracting effect.

[0014] (5) The main body may contain an ultraviolet luminescent material.

[0015] According to the above configuration, since the artificial bait contains an ultraviolet luminescent substance, it is excited by ultraviolet light and emits fluorescence, which causes squid, shrimp, fish, etc. to mistake the artificial bait to which the artificial bait buoyancy adjustment device is attached for a living creature, thereby achieving a fish-attracting effect. Effect of the Invention

[0016] According to the above configuration, it is possible to provide a buoyancy adjuster for an artificial lure that can be easily attached to the artificial lure and can keep the artificial lure in a substantially horizontal position. [Brief description of the drawings]

Figure 3 shows an example of an artificial bait to which a buoyancy adjustment body for artificial bait according to an embodiment of the present invention is attached.

Note that in this embodiment, the foreground of Fig. 2(B) is the front of the buoyancy adjustment body for artificial bait 1, the background of Fig. 2(B) is the rear of the buoyancy adjustment body for artificial bait 1, the right side of Fig. 2(B) is the right side of the buoyancy adjustment body for artificial bait 1, the left side of Fig. 2(B) is the left side of the buoyancy adjustment body for artificial bait 1, the top of Fig. 2(B) is the upper side of the buoyancy adjustment body for artificial bait 1, and the bottom of Fig. 2(B) is the lower side of the buoyancy adjustment body for artificial bait 1.

[0019] The artificial bait buoyancy adjusting body 1 according to this embodiment is detachably attached to the artificial bait 2. First, the artificial bait 2 will be described with reference to FIG. 3. The artificial bait 2 is a squid fishing tool, which is a fishing rod for squid fishing, and includes an artificial bait body 21 made of, for example, plastic, silicone rubber, or the like, and a needle part 22 having a plurality of needles 221 made of stainless steel or the like attached to the end of the artificial bait body 21. In this embodiment, the artificial bait body 21 is elongated in the up-down direction (vertical direction) and has a shape imitating a fish, and a line eye 21A for passing a fishing line (not shown) is provided at its upper end. Two needle parts 22 are attached to the lower end of the artificial bait body 21. The upper needle part 22 is referred to as the upper needle part 22A, and the lower needle part is referred to as the lower needle part 22B. When it is not necessary to distinguish between the upper needle part 22A and the lower needle part 22B, they are referred to as the needle part 22. The needle portion 22 has a plurality of needles 221. The needle 221 of the upper needle portion 22A will be described as an upper needle 221A, and the needle 221 of the lower needle portion 22B will be described as a lower needle 221B. When there is no need to distinguish between the upper needle 221A and the lower needle 221B, they will be described as needles 221.

[0020] The multiple needles 221 are arranged in a circle when viewed from above. The needles 221 are rod-shaped with sharp tips, and have a rear end extending downward, a bent portion bent diagonally upward at the lower end of the rear end, and a tip portion extending diagonally upward from the bent portion. Here, the rear end of the needle 221 is fixed to the artificial bait body 21, and thus the needle portion 22 is attached to the artificial bait body 21 such that the tip of the needle 221 protrudes diagonally upward from the artificial bait body 21.

[0021] An example of a tackle using the artificial bait 2 of this embodiment is as follows. A plurality of leaders are tied at a given interval (for example, at intervals of 70 to 100 cm) to a main line having a weight at its tip, and an artificial bait 2 is attached to the tip of each leader. Note that the tackle using the artificial bait 2 is not limited to this tackle. Here, if the artificial bait 2 is not attached to the artificial bait buoyancy adjusting body 1 of this embodiment, the weight of the lower end (needle part 22) may cause the artificial bait main body 21 to assume an approximately vertical or oblique position in the water (including the water surface and bottom), and it may not be possible to maintain an approximately horizontal position.

[0022] The artificial bait to which the buoyancy adjusting body for artificial bait 1 according to this embodiment is attached is not limited to the plastic squid shown as the artificial bait 2, but may be any artificial bait that has an artificial bait body and a needle part with multiple needles attached to the end of the artificial bait body. For example, the buoyancy adjusting body for artificial bait 1 can be attached to an artificial bait called "Plazuno", which is a plastic rod-shaped body with a needle part attached, or an artificial bait called "Egi", which has a sinker (weight) and is used by being sunk deep underwater. The target of the artificial bait is not limited to squid, but may be shrimp or fish. The needle part of the "Plazuno" or "Egi" is preferably configured similarly to the needle part 22 of the artificial bait 2.

[0023] 2(A)(B) and 3(A)(B), the buoyancy adjusting body 1 for artificial bait has an internal space 110, a main body 11 in which a buoyant body 13 is fitted, a first attachment part 121A protruding from a predetermined position (left position) on the side of the main body 11, and a second attachment part B protruding from a position (right position) on the side of the main body 11 substantially opposite to the first attachment part 121A. The first attachment part 121A is attached to one (first needle) of the multiple lower needles 221B of the artificial bait 2, and the second attachment part 121B is attached to another (second needle) of the multiple lower needles 221B of the artificial bait 2, whereby the buoyancy adjusting body 1 for artificial bait is attached to the lower needle part 22B of the artificial bait 2. It is to be noted that the buoyancy adjusting body 1 for artificial bait may be attached to the upper needle part 22A instead of the lower needle part 22B. The configuration of each part of the buoyancy adjusting device for artificial bait 1 will be described in more detail below.

[0024] The main body 11 has a concave shape (bowl shape) and has an opening 112 on the upper side. Specifically, the concave upper surface is covered with a lid 111 having an opening 112 formed in the center to form an internal space 110. The lid 111 is formed integrally with the other parts of the main body 11. The buoyant body 13 in the internal space 110 of the main body 11 is semispherical and formed so as to fit into the inside of the internal space 110 without any gaps. The buoyant body 13 is provided up to the position of the lid 111 of the internal space 110, but may be provided up to a position slightly below the lid 111 of the internal space 110 of the main body 11. The buoyant body 13 is bonded to the inside of the main body 11, but may not be bonded. The buoyant body 13 is formed of a highly buoyant material such as expanded polystyrene (EPS), which makes it possible to impart buoyancy to the lower end of the artificial bait 2 to which the artificial bait buoyancy adjustment body 1 is attached.

[0025] The first attachment portion 12A is a member provided so as to protrude from the upper left end of the side of the main body 11. The first attachment portion 12A is a plate-like member having a substantially semicircular shape in a plan view, and is formed so that the arc of the semicircle faces outward. The first attachment portion 12A has a through hole 121A in the vertical direction for inserting one (first needle) of the multiple needles 221 of the artificial lure 2. The second attachment portion 12B is a member provided so as to protrude from the upper right end of the side of the main body 11. The second attachment portion 12B is a plate-like member having a substantially semicircular shape in a plan view, and is formed so that the arc of the semicircle faces outward. The second attachment portion 12B has a through hole 121B in the vertical direction for inserting one (second needle different from the first needle) of the multiple needles 221 of the artificial lure 2.

[0026] The main body 11, the first mounting part 12A, and the second mounting part 12B are integrally formed with the main body 11. This allows the buoyancy adjuster for artificial bait 1 to be easily manufactured. As described above, since the main body 11 is bowl-shaped, it is easy to remove from a mold when molding, etc., and this also allows the buoyancy adjuster for artificial bait 1 to be easily manufactured. In addition, the main body 11, the first mounting part 12A, and the second mounting part 12B are made of a soft material (resin, rubber, etc.) that can be elastically deformed, which allows the needle 221 to be easily inserted into the through hole 121A and the through hole 121B by deforming the main body 11, the first mounting part 12A, and the second mounting part 12B. In addition, the deformation widens the range of dimensions of the artificial bait 2 to which the buoyancy adjuster for artificial bait 1 is attached.

[0027] The main body 11, the first attachment part 12A, and the second attachment part 12B contain a phosphorescent material (such as phosphorescent pigment powder), which stores natural light and emits phosphorescence when the surroundings are dark, such as at night. This allows squids, shrimps, fishes, etc. to mistake the artificial bait 2 to which the artificial bait buoyancy adjuster 1 is attached for a living creature, thereby obtaining a fish-attracting effect. The main body 11, the first attachment part 12A, and the second attachment part 12B may contain an ultraviolet emitting material (such as ultraviolet emitting pigment powder) instead of or in addition to the phosphorescent material (such as phosphorescent pigment powder). This allows the ultraviolet emitting material to be excited by ultraviolet light and emit fluorescence, allowing squids, shrimps, fishes, etc. to mistake the artificial bait 2 to which the artificial bait buoyancy adjuster 1 is attached for a living creature, thereby obtaining a fish-attracting effect.

[0028] [Method of manufacturing buoyancy adjustment body for artificial bait] Hereinafter, with reference to Fig. 1 (A) (B), an example of a manufacturing method of the buoyancy adjusting body 1 for artificial bait according to this embodiment will be described. A powder of a phosphorescent pigment and / or a powder of an ultraviolet luminescent pigment is mixed into an elastically deformable soft material (such as resin or rubber). Then, the main body 11, the first mounting part 12A, and the second mounting part 12B are integrally formed by die molding or the like. Then, a through hole 121A is formed in the first mounting part 12A, and a through hole 121B is formed in the second mounting part 12B. Furthermore, an opening 112 is formed in the lid 111. Note that the through hole 121A, the through hole 121B, and the opening 112 may be formed during the above die molding. Then, the buoyant body 13 is manufactured by molding polystyrene foam or the like, and is fitted into the internal space 110 from the opening 112 of the main body 11. Here, the buoyant body 13 may be adhered to the internal space 110 by an adhesive or the like.

[0029] [How to attach the buoyancy adjustment unit for artificial bait to the artificial bait] Hereinafter, with reference to Figs. 4(A), (B), and (C), an example of a method for attaching the buoyancy adjusting body for artificial bait 1 to the artificial bait 2 according to this embodiment will be described. The buoyancy adjusting body for artificial bait 1 is attached to the lower needle part 22B of the artificial bait 2 as described above. Specifically, as shown in Fig. 4(A), one of the lower needles 221B of the lower needle part 22B is inserted from the upper side of the through hole 121B of the first attachment part 12B. Here, the bent part of the lower needle 221B is inserted into the through hole 121B. This allows the second attachment part 12B to be attached to the lower needle 221B. Next, the main body 11 is tilted in the direction shown by the arrow in Fig. 4(A), and the first attachment part 12A is brought closer to the lower needle part 22B as shown in Fig. 4(B).

[0030] Then, as shown in FIG. 4(C), while stretching the buoyancy adjusting body for artificial bait 1, the lower needle 221B, which is located at a position substantially opposite to the lower needle 221B into which the through hole 121B of the lower needle part 22B is inserted, is inserted from above the through hole 121A of the first attachment part 12A. Here, the bent part of the lower needle 221B is inserted into the through hole 121B. As a result, the first attachment part 12A is attached to the lower needle 221B. Here, as shown in the example of FIG. 4(C), all the bent parts of the lower needles 221B of the lower needle part 22B may bend the lid body 111 toward the internal space 110 and abut against the upper end surface of the buoyant body 13 via the lid body 111. This type of attachment configuration is achieved by providing the buoyant body 13 not to the position of the lid body 111 of the internal space 110, but to a position slightly below. As shown in Figure 2 (B), when the buoyant body 13 is provided up to the position of the lid body 111 of the internal space 110, the bent portion of the lower needle 221B abuts against the upper end surface of the buoyant body 13 via the lid body 111 without bending the lid body 111. In this manner, the buoyancy adjustment body 1 for an artificial bait is attached to the artificial bait 2. Note that in Figures 4 (A), (B), and (C), the second attachment portion 12B is attached to the lower needle 221, and then the first attachment portion 12A is attached to the lower needle 221, but the attachment order may be reversed.

[0031] According to the buoyancy adjusting body for artificial bait 1 of this embodiment described above, the buoyancy adjusting body for artificial bait 1 can be attached to the artificial bait 2 simply by inserting the lower needle 221B of the lower needle part 22B into the through hole 121A of the first attachment part 12A and inserting a lower needle 221B different from the lower needle 221B into the through hole 121B of the second attachment part 12B, and the buoyancy adjusting body for artificial bait 1 can be easily attached to the lower end part of the artificial bait 2. As a result, the buoyancy adjusting body 13 fitted into the main body 11 can impart buoyancy to the lower end part of the artificial bait 2, and the artificial bait 2 can be brought into an approximately horizontal state even if the artificial bait 2 is formed so as not to be able to take an approximately horizontal position underwater (including the water surface and the water bottom).

[0032] (Modification) (1) In the buoyancy adjusting device for artificial bait 1 according to this embodiment, the main body 11 is formed in a bowl shape, but it may be another shape, such as a polyhedron with a recess, as long as it has an internal space 110. Also, in the main body 11, the internal space 110 is covered with a lid 111, but it does not have to be covered.

[0033] (2) In the artificial bait buoyancy adjusting body 1 according to this embodiment, the first attachment part 12A and the second attachment part 12B are plate-like members that are substantially semicircular in plan view, but are not limited to this shape, and may be formed so that the through holes 121A, 121B are formed and the lower needle 221B of the lower needle part 22B can be inserted therein. Furthermore, the main body 11, the first attachment part 12A, and the second attachment part 12B do not necessarily have to be formed integrally, and may be formed separately and connected by a member or the like. Furthermore, the first attachment part 12A and the second attachment part 12B protrude (outward) from the upper end of the side part of the main body 11 so as to protrude substantially horizontally (outward), but may be formed so as to protrude outward obliquely upward, or may protrude inward.

[0034] (3) In the buoyancy adjusting body for artificial bait 1 according to this embodiment, the main body 11, the first mounting part 12A, and the second mounting part 12B are all made of an elastically deformable soft material, but some of them may be made of an elastically deformable soft material. Also, all of them may be made not elastically deformable. For example, a configuration may be adopted in which an elastic member is inserted between the main body 11 and the first mounting part 12A, and between the main body 11 and the second mounting part 12B, and the through holes 121A, 121B can be inserted into the lower needle 221B while stretching this member.

[0035] (4) In the buoyancy adjustment body 1 for artificial bait of this embodiment, the main body 11, the first attachment part 12A, and the second attachment part 12B contain a phosphorescent substance (such as phosphorescent pigment powder) and / or an ultraviolet luminescent substance (such as ultraviolet luminescent pigment powder), but they do not have to contain them.
