Description

[Technical Field]

[0001] The present invention relates to a lure used when fishing. [Background technology]

[0002] Metal lures (also called metal jigs) that have an external pattern similar to that of a real fish have been known. For example, as disclosed in Patent Document 1, such lures have an eye (front eye) at the front end to which a line from a reel is attached, and an eye (rear eye) at the rear end to which a rear hook (fishhook) is attached. A blade may also be attached to the rear eye to enhance the fish-attracting effect. In this case, the blade and rear hook are attached to the rear eye via a swivel because the line is prone to tangle if they are fixed.

[0003] The lures are used in fishing methods such as retrieving, in which they are cast a long distance and then reeled in, or in falling, in which they are dropped from a boat or cast a long distance and then reeled in. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6047788 Summary of the Invention [Problem to be solved by the invention]

[0005] 7(a) and 7(b), when a conventional fishing lure 100 falls, the blade 105 and rear hook 106 attached to the rear eye 101 via the swivel 102 create resistance, causing the lure to fall with its head pointing downward. As a result, the rear side rises up, narrowing the gap between the line 200 and the fishing lure 100, making it easier for the rear hook 106, which rotates together with the blade 105, to become entangled in the line 200, and line trouble to occur. In particular, because the rear eye 101 protrudes rearward from the rear end of the fishing lure 100, the rotation range of the rear hook 106 is wide, making it easier for the rear hook 106 to pick up the line 200, and the above-mentioned line trouble to occur.

[0006] The present invention has been made with an eye on the above-mentioned problems, and aims to provide a lure that is less likely to cause line trouble even when operated during fall fishing. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the lure of the present invention is characterized by having a main body with a front eye for the line provided at the front end and a rear eye for the rear hook provided at the rear end, and a tail fin provided at the rear side of the main body and having a flat surface that is positioned above the rear eye and straightens the airflow.

[0008] The main body of the lure with the above-mentioned configuration has a flat tail fin located above the rear eye, which provides a streamlining effect and stabilizes the lure's fall posture as it falls into the water. Also, when the lure falls with a rear hook or blade attached to the rear eye, the tail fin of the main body is located above the rear eye, which narrows the range of motion of the rear hook or blade, stabilizing the main body with the streamlining effect and making it less likely to get tangled in the rear hook or blade line. [Effects of the Invention]

[0009] According to the present invention, a lure is obtained that is less likely to cause line trouble even when operated for falling during actual fishing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, one embodiment of the lure according to the present invention will be described. In the following description, when specifying the directionality of the lure (in this embodiment, the main body shaped like a fish), the direction of travel of the lure in water (head side in FIG. 2) is defined as the front (forward, front end), the opposite side of the direction of travel (tail side in FIG. 2) is defined as the rear (rear, rear end), the dorsal side is defined as the top (upper), and the ventral side is defined as the bottom (lower). Also, the direction perpendicular to the front-to-back direction and the up-to-down direction shown in FIG. 2 is defined as the width direction.

[0012] 1(a) and 1(b) are diagrams showing an embodiment of a lure according to the present invention. The lure 1 according to this embodiment is called a metal jig, and its main body 2 is formed in a shape that resembles the shape of a small fish (baitfish). For this reason, patterns such as scales and eyes are applied to the main body 2 by various methods, such as printing, attaching a sticker (including a hologram sticker), or hot stamping. The shape and method of applying such patterns are not limited, and various methods other than those described above are possible.

[0013] The main body 2 is preferably made of metal so that it can be cast far, and for example, by forming it from tungsten, which has a high specific gravity, it can be made heavy and compact. In this case, the formation of a tail structure, which will be described later, ensures a stable falling state, so it can sink deep and quickly despite its small size.

[0014] A first eye 3a for the line, to which the line unwound from the reel is connected, is provided on the tip side of the main body 2. A second eye 3b for the rear hook, to which a rear hook or the like is connected, is provided on the rear end side of the main body 2. In this embodiment, the first eye 3a is provided on the top surface of the main body 2, but it may also be provided on the tip edge (hereinafter, the first eye for the line, to which the line is connected, will be referred to as the tip eye 3a). The second eye 3b is provided at the rearmost position of the main body 2, and the upper side of the rear eye 3b is covered by the tail 20 described below (hereinafter, the second eye covered by the tail will be referred to as the rear eye 3b).

[0015] As shown in Figure 3, one end 7a of a swivel 7 is attached to the rear end eye 3b with a split ring 5A attached. As is well known, the swivel 7 has a fixed part 7A and a movable part 7B that rotates coaxially with the fixed part 7A. When the split ring 5A is attached to the one end 7a on the fixed part 7A side and this is attached to the rear end eye 3b, the movable part 7B becomes rotatable coaxially with the fixed part 7A. A split ring 5B is attached to the other end 7b on the movable part 7B side, and a blade 8 and a rear hook 9 that enhance the fish-attracting effect are attached to this split ring 5B.

[0016] In the following description, the components attached to the rear end eye 3b, specifically in this embodiment the split ring 5A, swivel 7, split ring 5B, blade 8, and rear hook 9, are collectively referred to as mechanism parts 10. Such mechanism parts 10 may include components other than those described above, or may be missing some of the components (for example, the blade 8). Furthermore, the shape, size, number of installed components, etc. of each component can be modified as appropriate. Furthermore, the lure of the present invention may be implemented with the above-mentioned tackle parts 10 attached to the rear end eye 3b of the main body 2 in advance, or may be implemented (sold, etc.) with only the above-mentioned main body 2.

[0017] A tail fin 20 is disposed above the rear eye 3b on the rear side of the main body 2, and as shown in Figure 2(c), this tail fin 20 covers the rear eye 3b so that it is not visible when the main body 2 is viewed from above. The tail fin 20 is also structured with a flat surface so that it can perform the function of rectifying the flow of the lure as it moves through the water.

[0018] The tail 20 of this embodiment has a structure including a first portion (also referred to as a vertical tail) 21 that protrudes upward relative to the main body 2, and a second portion 22a and a third portion 22b (also referred to as a horizontal tail 22) that protrude laterally on both sides of the first portion 21 and are integrally formed with the first portion 21. The first to third portions are all formed in a substantially plate-like shape and have a structure including flat surfaces 21A, 21B, 22A, and 23A, and the presence of such flat surfaces at the rear end stabilizes the behavior of the main body 2.

[0019] Note that the flat surface here means a rectifying surface that has a rectifying effect and is free of any irregularities that would cause turbulence when the main body 2 moves in water (a surface state that does not destabilize the behavior of the main body 2), and includes, for example, a straight surface, a curved surface, or a composite surface that combines these. In addition, in a configuration in which a vertical tail and a horizontal tail are provided as in this embodiment, it is preferable to form flat surfaces on both widthwise sides of the vertical tail 21 (planes 21A and 21B in FIG. 1) and on both vertically-direction sides of the horizontal tail 22 (planes 22A and 23A in FIG. 1), taking stability into consideration.

[0020] The tail fins 20 only need to be formed at the rear end of the main body 2, and as shown in Figure 2(a), if the total length of the main body 2 is L, it is preferable to form them rearward from a position 0.3L from the rear end of the main body 2 (the rearmost position P). This gives the main body 2 a natural shape for small fish, improving the fish-attracting effect. Furthermore, by forming the tail fins 20 up to the part P, it is possible to effectively prevent the rig parts 10 from getting tangled in the line.

[0021] The tail fin 20 may be configured to have only a horizontal stabilizer 22 that protrudes to the side (preferably both sides) of the main body 2 so that the rotation of the tackle part 10 can be restricted even if the tackle part 10 rotates counterclockwise around the rear end eye 3b (see Figure 4). The width W of the horizontal stabilizer 22 that protrudes to the side is preferably set to be equal to or less than the maximum width W1 of the main body 2, taking into consideration a range that is natural for the shape (design) of the fish and can effectively prevent the tackle part 10 from getting tangled in the line. In addition, by making the horizontal stabilizer 22 into a generally triangular shape that gradually widens as it moves rearward, it is possible to enhance the rectifying effect.

[0022] It is preferable that the tail fin 20 has a vertical tail fin 21 formed in addition to the horizontal tail fin 22. Forming such a vertical tail fin 21 stabilizes the behavior of the main body 2 in the width direction, and furthermore makes the tail fin appear to be like that of an actual small fish, improving the bite of fish (fish eaters). In particular, by forming the tail fin into a shape that protrudes higher toward the rear (approximately triangular), it is possible to more closely resemble the tail fin of an actual small fish.

[0023] In this embodiment, the main body 2 is provided with a restricting portion 30 that protrudes rearward below the tail unit 20, and is formed so that a recess 30S that is recessed forward is formed between the lower surface 23A of the tail unit 20 and the upper surface of the restricting portion 30. The rear end eye 3b is disposed within this recess 30S, with one end of the rear end eye 3b fixed to the lower surface 23A of the tail unit 20 and the other end of the rear end eye 3b fixed to the upper surface of the restricting portion 30. Therefore, the rear end eye 3b is disposed forward of the position P of the rear end of the main body 2 within the recess 30S, and the lateral sides of the rear end eye 3b are fixed in an open state.

[0024] By locating the rear eye 3b in the recess 30S formed by the restricting portion 30 described above, the vertical rotation of the mechanism part 10 can be restricted within a certain range, making it possible to further prevent entanglement with the line, as shown in Fig. 4. In other words, if the restricting portion 30 were not formed, the mechanism part 10 would rotate significantly in the clockwise direction and potentially become entangled with the line, but by forming the restricting portion 30, it is possible to prevent such entanglement.

[0025] By positioning the rear end eye 3b in the recess 30S forward of the position P of the rear end of the main body 2, it is possible to effectively restrict rotation even if the tackle part 10 is somewhat long. In addition, it is preferable to form a rotation restricting portion 22B on the rear end edge of the tail fin 20, as shown in Figure 5, so as to restrict rotation of the swivel 7 that constitutes the tackle part 10. Such a rotation restricting portion 22B can be formed by recessing the rear end edges of the second and third portions 22a and 22b that constitute the horizontal stabilizer in a curved shape. By forming such a rotation restricting portion 22B, the rotating swivel 7 can be easily accommodated, effectively preventing tangling of the line.

[0026] Furthermore, in the configuration of the lure described above, the tail fins 20 are formed so that they are positioned above the center of gravity G of the main body 2 (the lowest position P1 of the tail fins 20 is above the center of gravity G). In this configuration, the main body 2 falls stably from the ventral side, and the configuration of the tail fins 20 described above and the relative positions of the tail fins 20 and the rear-end eye 3b effectively prevent the rig parts 10 from getting tangled in the line. In particular, even if the lure moves in an arc below the boat after being cast on a boat, the main body 2 can sink stably with the ventral side, and the arrangement of the tail fins 20 described above effectively prevents the rig parts 10 from getting tangled in the line.

[0027] 4, in a configuration in which a split ring 5A is attached to the rear end eye 3b, the restricting portion 30 is preferably formed so that its cross-sectional diameter is smaller than the diameter of the split ring 5A attached to the rear end eye 3b, so that the split ring 5A fits in (see FIG. 6). In other words, when the lure is to be sold with the tackle part 10 attached, it is sufficient to connect a split ring 5A of such a size.

[0028] With this configuration, the split ring 5A can be fixed by abutting against the restricting portion 30, so that when attaching the components of the device part 10 (such as the swivel 7) using pliers or the like, the split ring 5A can be stabilized, making it easier to assemble and remove the device.

[0029] According to the lure 1 configured as described above, the tail fin 20 provided on the rear side of the main body 2 provides a streamlining effect, stabilizing the behavior of the lure as it falls. Furthermore, by providing the rear end eye 3b below the tail fin 20, even if the tackle parts (blade 8 and rear hook 9) attached to the rear end eye 3b rotate, they will not pick up the line from the reel, preventing line trouble. Furthermore, even if the user attaches their preferred tackle parts to the main body 2, such effects can be achieved.

[0030] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways. Although a metal jig type lure has been exemplified, the present invention can be applied to various types of lures, and the configuration of the main body 2 (size, material, number of eyes, configuration of rig parts, etc.) can be modified accordingly.

[0031] Furthermore, the tail 20 does not have to be configured such that the horizontal and vertical tails cross in a crisscross pattern as in this embodiment. For example, the tails may be inclined upward or downward, such as crossing in an inclined state (X-shape). Furthermore, the attachment positions and sizes of the first eye 3a and the second eye 3b can also be changed. [Explanation of symbols]
