Abstract
Description
Technical Field
[0001] The present invention relates to a tackle for fugu fishing.
Background Art
[0002] Since fugu inhabit fish reefs near the seabed, fugu fishing is carried out by placing the tackle near the seabed (bottom fishing).
[0003] [[ID=1⑤]] As a conventional tackle for fugu fishing, as shown in FIG. 3 of Patent Document 1, a weight tied to a main line, a J-shaped baiting needle with a hook part embedded and fixed at the lower part of the weight, a leader tied to the weight, and a cut-off needle tied to the lower end of the leader and arranged below the baiting needle are generally used. When the fish bite on the bait attached to the baiting needle and the fish signal (hit) is transmitted to the angler's hand through the main line, when the rod is lifted accordingly, the cut-off needle catches the fugu and is lifted. Of course, it is also possible to catch the fugu with the baiting needle.
[0004] In FIG. 1 of Patent Document 1, a through hole is drilled in the weight of the above tackle, and the baiting needle is tied to the main line inserted through the through hole, so that the baiting needle can expand, contract, and slide independently, and the hit is absorbed by the weight and is easily transmitted to the angler's hand through the main line. A tackle for fugu fishing is also disclosed.
[0005] Further, Patent Document 2 discloses a tackle for fugu fishing, which includes a weight body tied to a main line, a J-shaped baiting needle with a hook part embedded and fixed at the lower part of the weight body, a stainless steel hanging body with the upper end part embedded and fixed at the lower part of the weight body and extending downward below the baiting needle, an arm-shaped unit with the upper end part fixed in the middle of the hanging body and bent downward below the baiting needle, a leader tied to the lower end part of the arm-shaped unit, and a cut-off needle tied to the lower end part of the leader and arranged below the baiting needle. It is said that when the lower end of the hanging body hits the seabed during bottom fishing, and when the arm-shaped unit guards directly below the baiting needle, the occurrence of snagging by the baiting needle is prevented.
[0006] Furthermore, as shown in Figure 5, commercially available pufferfish fishing rigs 51 include a stainless steel vertical linear body 53 tied to the main line 52, a bait hook 54 with its eye fixed to the upper part of the vertical linear body 53, a weight 55 fixed to the lower part of the vertical linear body 53 and located below the bait hook 54, a horizontal linear body 56 extending forward from the weight 55, and a cuttlefish hook 58 with a leader 57 attached to the tip of the horizontal linear body 56. [Prior art documents] [Patent Documents]
[0007] [Patent Document 1] Japanese Patent Publication No. 2005-192477 [Patent Document 2] Japanese Patent Publication No. 2015-80417 [Overview of the project] [Problems that the invention aims to solve]
[0008] However, with the conventional pufferfish fishing rigs mentioned above, you can only know that a pufferfish has approached the rig when it bites the bait attached to the hook. Before that bite, you cannot know that a pufferfish is approaching the rig, even if it is.
[0009] Therefore, the object of the present invention is to provide a pufferfish fishing rig that allows the user to know when a pufferfish is approaching the rig before it bites the bait attached to the hook. [Means for solving the problem]
[0010] [1] A fishing rig for catching pufferfish, which includes a pufferfish detection body that extends from a point spaced both upward and laterally away from the eye of the bait hook, and detects the approach of a pufferfish when it comes into contact with the body. In this application, "upper" refers to the direction directly above the base of the bait hook, "front" refers to the direction towards the hook tip when viewed from the shank of the bait hook, and "side" refers to the direction perpendicular to the plane formed by the shank and the hook tip of the bait hook.
[0011] [Effect] When pufferfish are attracted to the bait attached to the hook and approach the rig, they often swim around the area above and to the side of the hook's eye before biting the bait. This makes them more likely to come into contact with the pufferfish detection device that extends past this area. Therefore, the approach of a pufferfish can be detected by the pufferfish contacting the detection device before the pufferfish bites the bait.
[0012] [2] The pufferfish fishing rig described in [1], comprising two pufferfish detection bodies: a first pufferfish detection body that extends in the front-to-back direction, passing through a location 10 to 70 mm above the eye of the bait hook and 20 to 100 mm to one side; and a second pufferfish detection body that extends in the front-to-back direction, passing through a location 10 to 70 mm above the eye of the bait hook and 20 to 100 mm to the other side. These separation distances and locations were measured with the baiting hook 6 unbaited, the cuttlefish hooks unconnected to the pufferfish detection bodies 7a and 7b, and the rig 1 suspended in the air by the main line 2, as shown in Figure 2.
[0013] [Effect] Pufferfish swim through these two locations particularly often before approaching the bait attached to the hook. Therefore, by providing two pufferfish detection units that extend in the front-to-back direction and pass through these locations, the probability of a pufferfish coming into contact with the pufferfish detection units can be increased.
[0014] [3] A pufferfish fishing rig according to [1] or [2], wherein the length of the pufferfish detection body in the front-to-back direction is 50 to 250 mm.
[0015] [Effect] The length of the pufferfish detection unit in the front-to-back direction is not particularly limited, but if it is 50 mm or longer, pufferfish are more likely to come into contact with it, and if it is 250 mm or less, the rig becomes more compact.
[0016] [4] The puffer fish detecting body of the puffer fish fishing device according to any one of [1] to [3] is composed of a metal wire, a resin wire, or a combination of a metal wire and a resin wire.
[0017] [5] The puffer fish fishing device according to any one of [1] to [4], including a first wire connected to the fishing line and a weight provided below the first wire.
[0018] [6] The puffer fish fishing device according to [5], wherein the puffer fish detecting body is connected to and supported by the first wire. <00于00078> [7] The puffer fish fishing device according to either [5] or [6], including a second wire protruding forward or downward from the weight.
[0020] [8] The puffer fish fishing device according to [7], wherein the tip of the baiting needle is connected to the second wire.
[0021] [9] The puffer fish fishing device according to any one of [1] to [8], wherein a cuttlefish needle is connected to the puffer fish detecting body. [Advantages of the Invention]
[0022] According to the puffer fish fishing device of the present invention, before the puffer fish hits the bait attached to the baiting needle, by the puffer fish coming into contact with the puffer fish detecting body, it is possible to know that the puffer fish is approaching the bait, which has an excellent effect. [Brief Description of the Drawings]
[0023] [Figure 1] Figure 1 is a perspective view of Example 1 of the puffer fish fishing device. [Figure 2] Figure 2(a) is a front view of Example 1 (in a state where the cuttlefish needle is not connected), (b) is a plan view, and (c) is a side view. [Figure 3] Figure 3(a) is a perspective view when the puffer fish approaches in Example 1, and (b) is a perspective view when it hits. [Figure 4]Figure 4(a) is a plan view of Example 2 of the pufferfish fishing rig, and (b) is a side view of Example 3. [Figure 5] Figure 5 is a perspective view of a conventional example of a fishing rig for pufferfish. [Modes for carrying out the invention]
[0024] <1> Pufferfish detection material The pufferfish detection body is preferably designed to extend in the front-to-back direction, passing above and to the side of the bait hook's eye, but it may also extend in the up-and-down direction. Pufferfish detection objects that extend in the front-to-back direction include those that extend in the front-to-back direction with a lateral tilt, and those that extend in the front-to-back direction with an up-and-down tilt. The pufferfish detection object is preferably positioned 10 to 70 mm above the eye and 20 to 100 mm laterally from the base of the pufferfish.
[0025] The material of the metallic wire is not particularly limited, but examples include stainless steel, steel, brass, etc. The thickness of the metal wire is not particularly limited, but a diameter of 0.6 mm or more is preferred. The material of the resin wire is not particularly limited, but examples include nylon, polyvinylidene fluoride (fluorocarbon), polyester, etc. The thickness of the resin wire is not particularly limited, but a diameter of 0.6 mm or more is preferred, and more specifically, it is preferable to use leader line of size 14 or larger.
[0026] <2> First linear body and second linear body The materials of the first and second linear bodies are not particularly limited, but examples include stainless steel, steel, brass, and the like. The first and second linear bodies may or may not be continuous. A configuration in which the first and second linear bodies are continuous and not fixed to the weight is preferable. This is because the bite on the bait hook is not weakened by the weight and is transmitted to the main line via the first and second linear bodies.
[0027] <3> weight The weight is not particularly limited; for example, various commercially available weights can be used. The weight may or may not be fixed to the second linear body. In the case where it is not fixed, the second linear body is slidably inserted through a through hole provided in the weight.
[0028] <4> Baiting hook The baiting hook is not particularly limited, and various commercially available baiting hooks can be used, for example. The base of the baiting hook may be fixedly connected to the second linear body, or it may be connected in a way that allows it to swing.
[0029] <5> Cutting needle The cuttlebone needle is not particularly limited, and various commercially available cuttlebone needles can be used, for example. By attaching a cuttlefish hook to the pufferfish detection body, it easily becomes a rig for cuttlefish fishing. It is also possible to catch pufferfish that have been caught on the baited hook without attaching a cuttlefish hook to the pufferfish detection device. [Examples]
[0030] Embodiments of the present invention will be described with reference to the drawings. Note that the structures, materials, numerical values, shapes, and dimensions described in the embodiments are illustrative and can be modified as appropriate without departing from the spirit of the invention.
[0031] [Example 1] The pufferfish fishing rig 1 of Embodiment 1 shown in Figures 1 to 3 comprises a first linear body 3 attached to the main line 2 and extending downward, a weight 4 provided below the first linear body 3, a second linear body 5 slidably inserted through the weight 4, a baiting hook 6 connected to the tip of the second linear body 5 extending from the weight 4, two pufferfish detection bodies 7a and 7b connected to the upper and lower middle part of the first linear body 3, and two cuttlefish hooks 8 connected to the front ends of each pufferfish detection body 7a and 7b.
[0032] The first linear body 3 is made of stainless steel wire. A ring-shaped connector is provided at the upper end of the first linear body 3, and the guide line 2 is tied to this connector.
[0033] A commercially available weight is used for weight 4. Weight 4 has a through hole that extends downwards in the front-to-back direction.
[0034] The second linear body 5 is made of a stainless steel wire that is continuous with the first linear body 3, and is bent forward from the lower end of the first linear body 3. The second linear body 5 is slidably inserted through the through hole of the weight 4 and is not fixed to the weight 4. A ring-shaped connecting portion is provided at the tip of the second linear body 5.
[0035] The baiting hook 6 includes a hook eye, a shaft extending downward from the hook eye, a bent section that curves forward from the shaft, a bent tip that curves upward from the bent section, a hook point located in front of the shaft, and a barb. The hook eye is, for example, ring-shaped, and this hook eye is rotatably hooked and connected to the ring-shaped connecting portion of the second linear body 5, so that the baiting hook 6 is suspended in a swingable manner and the shaft extends downward.
[0036] The two pufferfish detection units 7a and 7b detect the approach of pufferfish when they come into contact with them in the sea during use, as will be described later. Figure 2 shows the rig 1 suspended in the air by the main line 2 before use, with no bait attached to the baiting hook 6 and no cuttlefish hooks connected to the pufferfish detection units 7a and 7b, so that the pufferfish detection units 7a and 7b are in a forward-sloping position. In this state, the two pufferfish detection units 7a and 7b are: the first pufferfish detection unit 7a, which passes through a location Pa that is 10 to 70 mm (40 mm in the illustrated example) above the top of the base of the bait hook 6 and 20 to 100 mm (50 mm in the illustrated example) to one side; and the second pufferfish detection unit 7b, which passes through a location Pb that is 10 to 70 mm (40 mm in the illustrated example) above the top of the base of the bait hook 6 and 20 to 100 mm (50 mm in the illustrated example) to the other side.
[0037] Each pufferfish detection body 7a, 7b consists of a metal wire 9 at the rear and a resin wire 10 at the front joined together. The metal wire 9 is made of, for example, a stainless steel wire with a diameter of 1 mm, and consists of a portion that is connected to the upper and lower middle part of the first wire 3 and extends laterally, and a portion that curves from the end of the same portion and extends forward. The resin wire 10 is made of, for example, a No. 26 (0.84 mm in diameter) nylon leader and is connected to the front end of the metal wire 9 and extends forward. A leader stopper, for example, is provided at the front end of the resin wire 10.
[0038] The cuttlefish hook 8 is a commercially available cuttlefish hook (for example, one made by joining 2 to 4 single needles in an anchor shape). The leader 11 is tied to the upper end of the cuttlefish hook 8, and the upper end of the leader 11 is provided with a hook-shaped connector, which is then attached to the leader stopper of the pufferfish detection bodies 7a and 7b, for example.
[0039] As shown in Figure 3(a), the pufferfish fishing rig 1, configured as described above, is used by attaching bait (such as clams or shrimp) to the baiting hook 6, then letting out the main line 2 to sink it into the sea. Once the rig is detected to have reached the seabed, the main line 2 is reeled back slightly to position the rig slightly away from the seabed (bottoming). At this time, the first linear body 3 extends downward, the shaft of the baiting hook 6 extends downward, and each pufferfish detection body 7a, 7b extends forward in a downward-sloping manner.
[0040] As shown in Figure 3(a), when a pufferfish is attracted to the bait attached to the hook 6 and approaches the rig, it often swims around the vicinity of locations Pa and Pb before biting the bait, making it likely to come into contact with the pufferfish detection units 7a and 7b that extend in the front-to-back direction as they pass through these locations. Therefore, before the pufferfish bites the bait, the impact of the pufferfish contacting the pufferfish detection units 7a and 7b is transmitted to the angler's hand, allowing the angler to detect that a pufferfish is approaching the rig. This detection allows the angler to know that a bite is imminent and prepare accordingly. Then, as shown in Figure 3(b), when a pufferfish bites the bait, lifting the rod in accordance with the bite will cause the cuttlefish hook 8 to catch the pufferfish, allowing it to be reeled in.
[0041] [Example 2] The pufferfish fishing rig of Example 2 shown in Figure 4(a) (without the cuttlefish hook attached) differs from Example 1 only in that the pufferfish detection bodies 7a and 7b pass through the locations Pa and Pb and extend in the front-rear direction with a lateral inclination; otherwise, it is the same as Example 1. According to this embodiment 2, in addition to obtaining the same effects as in embodiment 1, it is easier to increase the distance between the two cut-out needles 8, 8.
[0042] [Example 3] The pufferfish fishing rig of Example 3 shown in Figure 4(b) (without the cuttlefish hook attached) differs from Example 1 only in that the pufferfish detection bodies 7a and 7b pass through locations Pa and Pb and extend in the front-rear direction with an even more downward slope than in Example 1; otherwise, it is the same as Example 1. According to this embodiment 2, in addition to obtaining the same effects as in embodiment 1, it is easier to lower the position of the cut-off needle 8.
[0043] It should be noted that the present invention is not limited to the embodiments described above, and can be appropriately modified and implemented without departing from the spirit of the invention. [Explanation of Symbols]
