[0001] The present invention relates to a fishing lure used for fishing.
Background Art
[0002] In fishing, which is collectively called lure fishing, fishing lures used include lures collectively called metal jigs that are made of metal and resemble the shape of fish, and soft lures collectively called soft lures that are made of soft resin or soft rubber and form a shape preferred by target fish. It is common practice to use various lures according to the target fish species to improve fishing results.
[0003] Since the metal jig is made of metal, it has a large specific gravity and can obtain a sufficient long casting distance with respect to the flying distance. However, it is well known that due to its large specific gravity, the sinking speed from hitting the water surface to reaching the bottom is fast.
[0004] In order to gather fish at the desired water depth with the metal jig, since the sinking speed is fast, the reel must always be wound, so the time from hitting the water to retrieving the lure is very short.
[0005] Also, since the soft lure is made of soft resin or soft rubber, etc., it has a small specific gravity. Although a sufficient flying distance cannot be obtained, because it is made of a soft material, its movement is soft, and it is possible to produce a soft movement preferred by the target fish species.
[0006] There is also a fishing rig collectively called a jig head rig. This is a rig for fishing where a pseudo-bait formed in a shape preferred by fish using soft resin or soft rubber, etc. is attached to a fishing hook with a weight attached to the base of the hook. It is one of the effective fishing methods for extending the distance in soft lure fishing where a flying distance cannot be expected.
[0007] For example, if you want to cast a soft lure, which is characterized by its gentle movement, over a long distance, you can aim to cast it far by using a jig head rig, or by using a rig that combines a worm and a weight as shown in Patent Document 1, or a rig with a structure like the one in Patent Document 2, but there were several problems. [Prior art documents] [Patent Documents]
[0008] [Patent Document 1] Japanese Patent Publication No. 2014-103917
[0009] [Patent Document 2] Japanese Patent Publication No. 2007-6869 [Overview of the project] [Problems that the invention aims to solve]
[0010] It is well known that to achieve more effective catches when fishing from land, you need to cast your lure further. To achieve this, it is common to use heavier lures to increase the casting distance. However, a challenge has been that making the lure heavier increases its sinking speed, which shortens the time it has to appeal to the target fish species underwater.
[0011] In lure fishing, as explained above, various rigs are well known, including metal jigs, soft lures, jig head rigs, and those described in Patent Documents 1 and 2. However, there was no rig designed for long-distance casting that could simultaneously suppress air resistance and control the sinking speed.
[0012] It is well known that when fishing from land, casting lures further expands the area you can search for fish in, leading to better results. However, using heavy lures limits their movement, so adding a softer movement to the lure can lead to better results.
[0013] Furthermore, controlling the sinking speed increases the time from when the lure hits the water surface until it reaches the bottom, allowing the target fish to recognize the lure for a longer period, which we believe will lead to better fishing results.
[0014] For example, the rig described in Patent Document 1, which combines a heavy weight and a soft worm, lacks a sense of unity between the weight and the worm, resulting in significant air resistance during long casts and flight, preventing it from achieving sufficient flight distance. Similarly, while rigs like the one in Patent Document 2 have a sense of unity between the weight and the worm, they lack a mechanism to control the sinking speed, thus failing to provide sufficient appeal time to the target fish species. [Means for solving the problem]
[0015] To achieve the above objective, the present invention has the following structure as its essence.
[0016] The present invention is a fishing lure having a weighted base and a bag-shaped covering structure made of soft resin or soft rubber.
[0017] The aforementioned fishing lure is characterized by having a structure that is attached to the weight portion, and because there is no step between the weight portion and the structure when the structure is attached, the structure does not detach due to centrifugal force and air resistance during long casts, and because the lure is a single unit during flight, air resistance is reduced.
[0018] The fishing lure of the present invention is characterized in that, after the main body of the lure hits the water surface, water enters the through-hole or slit provided in the weight portion when the fishing line is wound up with a reel, pushing out the covering structure, which then moves, and the sinking speed is controlled by the water resistance of the moved structure as it is subjected to the water.
[0019] The covering structure in operation is made of a soft material such as soft resin or soft rubber. By moving due to the resistance of water, it can create a soft movement to attract the interest of target fish, serving as a soft lure.
Advantages of the Invention
[0020] As described above, by combining a material with a large specific gravity and a material with a small specific gravity, the present invention enables the material with a small specific gravity to fly farther. Also, after hitting the water, the material with a small specific gravity operates and moves, making it possible to create a soft movement at a point farther from the land, which was impossible before. In addition, since the structure is subject to water bite resistance, it is possible to control the sinking speed, which was a problem in fishing with only heavy lures.
[0021] In addition, since it has a structure that is subject to water bite resistance, it is possible to swim the lure without dragging the seabed with the buoyancy due to water bite resistance even with a small number of reel winding operations, and it is possible to appeal to the target fish slowly and for a sufficient time.
[0022] In addition to controlling the sinking speed, the covering structure described above serves as a soft lure by moving under the resistance of water, and is characterized by having the effect of attracting the interest of target fish species.
[0023] The covering structure described above is characterized in that only that part can be exchanged, and the structure can be exchanged according to the target fish species.
[0024] In the above replacement operation, since the covering structure and the fishing hook do not interfere with each other, the replacement of the rig is easy.
[0025] From the above, the present invention has a structure that can simultaneously solve the problems of the long casting distance with only light lures and the sinking speed with only heavy lures, which were problems in fishing until now.
Brief Description of the Drawings
[0026] [Figure 1] Figure 1 is a schematic diagram showing the actual shape of this fishing lure. [Figure 2] Figure 2 shows the actual shape of this fishing lure when it is in operation. [Figure 3] Figure 3 is a longitudinal cross-sectional view of the fishing lure described above. [Figure 4] Figure 4 is a cross-sectional view along the line A-A in Figure 1. [Figure 5] Figure 5 is a longitudinal cross-sectional view showing the operating state of the covering structure of the present invention. [Modes for carrying out the invention]
[0027] This invention aims to simultaneously extend casting distance and control sinking speed in lure fishing.
[0028] As shown in Figures 3 and 4, the lure of the present invention has no steps, so the covering structure does not move before it hits the water surface due to air resistance caused by centrifugal motion during long-distance casting or air resistance during flight.
[0029] As shown in Figure 3, this lure consists of a weighted base 7 and a covering structure 8 that controls the sinking and rising speeds, attracting the interest of target fish species with its soft movement.
[0030] After the fishing lure hits the water, reeling it in pulls the lure in the direction of the eye (the knot in the fishing line) 2.
[0031] When the fishing lure is pulled in the direction of the eye (fishing line knot) 2, water enters the through-hole 9 provided in the main body, and the water that enters pushes out the edge of the structure that is covered by it, creating a step between the main body and the structure. Due to the resistance of the water, the structure moves with the eye (fishing line knot) 2 as a pivot point.
[0032] Figure 5 shows the state in which water enters the penetration 9 and the structure is in operation. The covering structure has a bag-like, parachute-like shape, so it receives water resistance to control the sinking speed, and because it moves due to water resistance, it is expected to attract the attention of fish and result in a good catch.
