Description

Technical Field

[0001] This invention relates to a fishing lure.

Background Art

[0002] Large fish such as black bass, large-mouth bass, catfish, and perch prey on small animals such as fish, earthworms, shrimp, crayfish, frogs, insects, and mice as bait. Lure fishing has become popular as a means of catching these large fish. In lure fishing, a lure is used. A fishing line is connected to the lure. The lure flies through the air by casting and eventually lands in the water. The lure swims in the water or on the water surface as the fishing line is wound. The fish that mistake this lure for bait bite the lure. The fishing hook attached to the lure pierces the fish, and the fish is caught.

[0003] Conventionally, there are two types of lures: a hard lure called a hard lure that uses a hard material such as hard plastic, wood, or metal for the body material, and a soft lure called a soft lure that uses a flexible material such as soft plastic, rubber, or elastomer for the body material.

[0004] Also, as a technique for casting the lure farther, a weight that can move in the front-rear direction of the lure is provided inside the lure. When casting, the weight moves to the rear of the lure by inertia, so that the flight attitude is stabilized and the lure flies farther. When reeling in, the weight moves to the front of the lure, so that the lure swims stably. This invention is disclosed in FIGS. 1 and 2 of Patent Document 1. The mechanism in which the weight moves to the rear of the lure when casting in Patent Document 1 is very effective in improving the flying distance of the lure. Generally, it is called center of gravity movement and is widely used in today's hard lures along with various derivative techniques.

[0005] On the other hand, the mounting of center of gravity movement is limited to hard lures only and has not spread to soft lures. The reasons why center of gravity movement has not been popularized in soft lures are as follows: When the lure body is molded with a soft material, the path set for the weight to move during casting is deformed due to the movement of the weight, and the weight does not move as intended. Also, soft lures are easily damaged and are generally consumables, so it is necessary to set the product price low. However, if a mechanism for center of gravity movement with high manufacturing costs is installed, the product price will become high. In the current injection molding technology for soft lures, it is difficult to mold a soft lure with a complex internal structure for the weight to move.

[0006] As a lure equipped with a center of gravity movement mechanism in a soft lure, a moving path is provided in the lure where the weight built into the lure can move back and forth. For part or all of the moving path where the weight moves back and forth, a moving path protection measure is taken by a structure having a bellows-like uneven shape, a coil shape, or a ring shape. Even when the lure is deformed and the moving path of the internal weight is bent, a space is secured by the moving path protection measure so that the weight can move back and forth. A lure is disclosed in FIG. 1 of Patent Document 2 and the like.

Problems to be Solved by the Invention

[0008] However, the lure disclosed in (Patent Document 2) is extremely difficult to manufacture and has a high manufacturing cost because it is necessary to manufacture a complex center-of-gravity shifting mechanism and to incorporate the center-of-gravity shifting mechanism therein to mold the body of the soft lure. Further, since the rubber or elastomer portion (body portion) of the soft lure is very easily damaged, the soft lure is generally a consumable item. For the lure of (Patent Document 2) in which the body portion and the center-of-gravity shifting mechanism cannot be separated, when the body portion is damaged, the entire lure becomes inoperative, so it is necessary to discard the high-cost center-of-gravity shifting mechanism as well. Due to the high manufacturing cost and short product life, it was not practical.

[0009] Therefore, the present invention provides a lure that, even when the body is formed of a flexible material, allows the weight to move inside the lure in the front-rear direction of the lure, and by the weight moving backward inside the lure due to inertia during casting, the lure flies farther, and during reeling, the weight moves forward of the lure so that the lure swims stably, and only the portion of the soft material that is easily damaged is replaceable, and moreover, the lure is easy to manufacture.

Means for Solving the Problems

[0010] The lure according to the present invention comprises a front body having a convex portion and a weight, and a rear body having a concave portion into which the convex portion can be inserted, wherein the convex portion has a space inside which the weight can move, and in a state where the convex portion is inserted into the concave portion, the weight can move inside the rear body.

[0011] Preferably, the main body of the front body has a space continuous with the space of the convex portion inside, and the weight can move from the space inside the main body of the front body to the space inside the convex portion.

[0012] Preferably, the material of the front body is hard plastic, The material of the rear body is characterized by being soft rubber, gel, or soft resin.

[0013] Preferably, The front body is provided with holes, and pins are inserted through the holes and the rear body.

[0014] Preferably, The cross-sectional shapes of the convex portion and the concave portion are polygons, ellipses, semi-circles, and shapes similar to the above shapes. In a state where the convex portion is not inserted into the concave portion, the volume of the inner portion of the concave portion is smaller than the volume of the convex portion.

[0015] Preferably, The front body has a groove portion. The rear body has a portion that can be inserted into the groove portion. The groove width of the groove portion is not constant, and the groove portion has a narrow groove width portion and a wide groove width portion. The wide groove width portion is located on the groove bottom side with respect to the narrow groove width portion.

[0016] Preferably, The outer surface of the convex portion is provided with a convex portion.

Advantages of the Invention

[0017] According to the present invention, it is possible to provide a lure that improves the flying distance of the soft lure, can change its shape according to the situation, and is easy to manufacture.

Mode for Carrying Out the Invention

[0019] Hereinafter, with reference to the drawings, the lure 1A of the first embodiment of the present invention will be described.

[0020] As shown in FIGS. 1 and 2, the lure 1A of the first embodiment includes a front body 2 having a convex portion 2a and a rear body 3 having a concave portion 3a into which the convex portion 2a can be inserted. Further, as shown in FIG. 8, the lure 1A of the first embodiment has a shape imitating a fish. Hereinafter, the direction toward the head of the lure 1A is defined as the front direction, the direction toward the tail is defined as the rear direction, the direction toward the back is defined as the upward direction, the direction toward the belly is defined as the downward direction, and the left and right directions are defined with respect to the front-rear direction.

[0021] In the lure 1A of the first embodiment, the material of the front body 2 is hard plastic. (1) Hard plastic Examples of hard plastic include AS resin (SAN), ABS resin (ABS), polycarbonate (PC), polylactic acid (PLA), polyamide (PA), polyurethane (PUR), and carbon fiber reinforced plastic (CFRP). In the lure 1A of the first embodiment, the rear body 4 is formed of a soft rubber, gel, or soft resin. (2) Soft rubber Examples of soft rubbers include synthetic rubbers such as silicone rubber, styrene-butadiene rubber (SBR), polybutadiene rubber (BR), butadiene-acrylonitrile rubber (NBR), polyisoprene rubber (IR), polychloroprene rubber (CR), ethylene-propylene copolymer rubber (EPM), ethylene-propylene-non-conjugated diene copolymer rubber (EPDM), urethane rubber, and fluororubber, and thermoplastic elastomers (TPE) such as styrene-based TPE, olefin-based TPE, vinyl chloride-based TPE, urethane-based TPE, ester-based TPE, amide-based TPE, chlorinated polyethylene-based TPE, Syn-1,2-polybutadiene-based TPE, Trans-1,4-polyisoprene-based TPE, and fluorine-based TPE. (3) Gel Examples of gels include silicone gel and acrylic resin gel. (4) Soft resin Examples of soft resins include vinyl chloride resin and polyolefin. Hereinafter, the term "soft material" is used as a general term for (2) to (4) above.

[0022] As shown in FIG. 2, the front body 2 and the rear body 3 are connected by inserting the convex portion 2a into the concave portion 3a. Inserting the convex portion 2a into the concave portion 3a is referred to as insertion P1. The convex portion 2a and the concave portion 3a are detachable. The front body 2 includes a weight 4 inside. The convex portion 2a has a space inside. The front body main body 2c (the portion of the front body 2 other than the convex portion 2a) has a space inside. The space inside the convex portion 2a and the space inside the front body main body 2c are continuous, and a movement path portion 2b is formed by the continuous space. The weight 4 can move in the movement path portion 2b, and as shown by the arrow M in FIG. 1, the weight 4 can move from the inside of the front body main body 2c to the inside of the convex portion 2a. When the lure 1A is viewed from the side with the convex portion 2a inserted into the concave portion 3a, the weight 4 can move from the inside of the front body 2 to the inside of the rear body 3.

[0023] With the above structure, even if the material of the rear body 3 is a soft material, the weight 4 can move inside the rear body 3. Even if the material of the rear body 3 is a soft material, the movement path portion 2b is formed of hard plastic like a lure equipped with conventional center of gravity movement, and the shape of the movement path portion 2b does not deform. Therefore, the problem that the movement of the weight is hindered due to the deformation (bending, shrinkage, etc.) of the movement path portion, which was an issue when mounting a center of gravity movement mechanism on a lure with a soft material as the body material, is solved. Even when using a soft material as the body material, the weight can move to the rear part of the lure (the part of the rear body 3 in the lure 1A) in the same way as a lure equipped with center of gravity movement formed only of conventional hard plastic during casting, and the same level of casting distance can be obtained.

[0024] In addition, since the convex portion 2a and the concave portion 3a can be fitted and detached, when the rear body 3, which is likely to be damaged due to the soft material, is damaged, only the rear body 3 can be replaced, and the front body 2, which has a high manufacturing cost and is not easily damaged, can continue to be used even if the rear body is damaged. In addition, as shown in FIG. 3, by preparing rear bodies of different shapes, according to the target fish and the situation of the fishing ground, for example, the rear bodies 3-1 (pin tail), 3-2 (shad tail), 3-3 (fish tail) can be freely replaced.

[0025] Furthermore, if the front body having a center of gravity movement mechanism as described above is formed of hard plastic and the rear body is formed of a soft material, as shown in FIG. 4, using the manufacturing method of existing hard lures (a manufacturing method in which the body is divided left and right and injection molded and then adhered), the part with a complex center of gravity movement mechanism (front body) can be manufactured, and the rear body having no complex structure can be manufactured using the manufacturing method of existing soft lures. Therefore, the problem that it is difficult to mold a soft material with a complex internal structure such as a center of gravity movement mechanism, and a lure with a body formed of a soft material cannot be equipped with a complex internal structure is solved, and it is possible to manufacture at low cost because it is possible to manufacture using the injection molding technology used in the manufacture of existing hard lures and soft lures.

[0026] The following describes the detailed shapes and structures of each part, and the effects obtained thereby.

[0027] As shown in FIGS. 1 and 2, the front body 2 includes a weight 4 made of a magnetic material or partially made of a magnetic material, and a movement path portion 2b through which the weight 4 can move from the inside of the front body main body 2c to the inside of the convex portion 2a. Further, the front body 2 includes a magnet 5 for fixing the weight to the front end portion of the movement path portion. When reeling in the lure, the weight is fixed to the front end portion of the movement path portion by the magnet, and due to the inertia during casting, the weight moves away from the magnet and moves to the rear end portion of the movement path portion. In the lure 1A of the first embodiment, the movement path portion is cylindrical, and as shown in FIG. 4, a semi-circular weight 4 can slide along the movement path portion as shown in FIG. 1, and the weight 4 moves from the front portion of the front body to the convex portion 2a due to the inertia during casting. The shapes of the movement path portion 2b and the weight 4 do not necessarily have to be limited to the above shapes. For example, as in the lure 1B of the second embodiment shown in FIG. 10, a structure in which a spherical weight 4 moves by rolling on a cylindrical movement path portion 2b may be used. Further, a structure may be used in which a shaft inserted through the weight is provided, both end portions of the shaft are locked to both end portions of the movement path portion 2b, and the weight can move along the shaft, or a structure provided with an elastic member that biases the weight in the forward direction of the lure.

[0028] Generally, for a lure, when reeling in, having the center of gravity in the forward (traveling direction) makes the swimming stable and makes it easier for fish to mistake it for bait. When casting, having the center of gravity in the rear (flight direction) results in a stable flight attitude and enables it to fly farther. For the above reasons, it is preferable that the weight is located more forward of the lure when reeling in and more rearward of the lure when casting. As shown in FIG. 2, by providing the movement path portion 2b, which is a continuous space from the inside of the front body main body 2c to the inside of the convex portion 2a, the weight 4 can move from the front portion of the front body 2 to the rear end portion of the convex portion 2a. Therefore, the lure 1 can swim stably when reeling in and fly well when casting.

[0029] In the lure 1A of the first embodiment, although the moving path portion 2b is linear, the shape of the moving path portion 2b is not limited to the above shape only. It is sufficient that the weight can move inside. For example, it may have a refracted shape like the lure 1B of the second embodiment shown in FIG. 12, or other curved shapes, etc.

[0030] As shown in FIG. 2, the rear body 3 is provided with a recess 3a, and the front body 2 and the rear body 3 are connected by inserting the convex portion 2a into the recess. In the natural state (the state where the front body 2 and the rear body 3 are separated) as shown in FIG. 9, the volume V2 of the inner part of the recess 3a is smaller than the volume V1 of the convex portion 2a. The insertion P1 is performed in a state where the rear body 3 is elastically deformed to widen the width of the recess 3a. In the state where the front body 2 and the rear body 3 are connected, the recess 3a is in a widened state compared to the natural state. Thus, the contracting force of the recess 3a is applied to the convex portion 2a, and the friction between the convex portion 2a and the recess 3a increases, so that the front body 2 and the rear body 3 are firmly connected.

[0031] Further, the convex portion 2a is provided with a convex portion 2a-2 on the surface, and the convex portion 2a-2 increases the friction between the convex portion 2a and the recess 3a, preventing the rear body 3 from coming off from the front body 2. The lures 1A and 1B of the first and second embodiments prevent the rear body 3 from coming off from the front body 2 by providing the convex portion 2a-2 on the surface of the convex portion 2a. However, for example, the rear body 3 may be prevented from coming off from the front body 2 by a wire or the like protruding at an angle perpendicular or nearly perpendicular to the direction of the insertion P1.

[0032] As shown in FIG. 9, since the vertical cross-section S1 of the convex portion 2a and the vertical cross-section S2 of the recess 3a are substantially semicircular, the rear body 3 is prevented from rotating (R) about the convex portion 2a as an axis (Z) with respect to the front body 2. The cross-sectional shapes of S1 and S2 do not need to be limited to substantially semicircular shapes. Any shape that can prevent the rear body 3 from rotating about the convex portion 2a as an axis with respect to the front body 2, for example, a substantially polygonal shape or a substantially elliptical shape, is acceptable.

[0033] As shown in FIG. 5, the front body 2 includes a groove portion G1 and a groove portion G2, and the upper end of the groove portion G1 and the lower end of the groove portion G2 are open. The groove portions G1 and G2 are linear grooves provided vertically at the rear portion of the front body 2 and opening rearward (in other words, the groove portion G2 is a groove provided in the front body 2 with the vertical direction of the lure 1 as the length direction, the left - right direction as the width direction, the front - rear direction as the depth direction, the front side as the groove bottom, and the rear side as the opening), and the groove portion G2 is located at the center in the left - right direction of the front body 2. Further, the rear body 3 includes a locking portion F1 and a locking portion F2 which are portions for being respectively inserted into the groove portion G1 and the groove portion G2. When connecting the front body 2 and the rear body 3, the locking portions F1 and F2 are respectively stretched (elastically deformed) in the vertical direction as shown by the arrow Q, and inserted into the groove portions G1 and G2 from the open ends of the groove portions G1 and G2 as shown by the arrow J. As shown in FIG. 6, the groove portions G1 and G2 have a portion N where the groove width is narrow and a portion W where the groove width is wider than N, and W is located in the direction of the groove bottom B with respect to N. Also, the locking portions F1 and F2 have a portion X that is wide in the left - right direction, and X is inserted into W. Since the groove width K1 of N is narrower than the left - right width K2 of W, even when a force is applied to the rear body 3 in a direction parallel to the convex portion 2a (the rear direction in FIG. 5) due to inertia during casting or the like, the rear body 3 remains fixed to the front body 2 without coming off the front body 2 due to the contact between N and X.

[0034] As shown in FIG. 5, even when a force is applied to the rear body 3 in a direction parallel to the convex portion 2a (the rear direction in FIG. 5) due to inertia during casting or the like, in order that N and X sufficiently contact and the rear body 3 does not come off the front body 2 in the rear direction, the angle θ formed by the groove portions G1 and G2 and the convex portion 2a preferably has a value between 30° and 150°.

[0035] In the lure 1A of the first embodiment, the front body 2 has two groove portions, i.e., a groove portion G1 located above the convex portion 2a and a groove portion G2 located below the convex portion 2a. However, only one of the groove portion G1 and the groove portion G2 may be provided, and if the rear body 3 is connected to the front body 2 without coming off during casting or the like, neither the groove portion G1 nor the groove portion G2 needs to be provided.

[0036] Hereinafter, the manufacturing method of the lure 1A of the first embodiment will be described. In order to manufacture a lure having a mechanism for shifting the center of gravity, since it is necessary to provide a space inside the lure and enclose a movable weight, when the traveling direction of the lure is taken as the front, it is preferable to first make parts obtained by dividing the lure body left and right, and then bond the left and right parts to enclose a space for the weight and the weight to move inside the lure. Further, since it is necessary to seal the lure in order to prevent water from entering inside during the above bonding, it is necessary to apply a strong pressure with a clip or the like from the left and right to perform the bonding. However, since the conventional lure made of a soft material deforms when pressure is applied, it is difficult to perform precise bonding, and it is difficult to enclose the mechanism for shifting the center of gravity by bonding the left and right parts, and the mechanism for shifting the center of gravity cannot be provided. However, since the front body of the lure 1A is made of a hard plastic, as shown in FIG. 4, the front body 2 can be manufactured in the same manner as a hard lure having a conventional center of gravity shifting mechanism by bonding the parts divided left and right, and mass production by injection molding is possible.

[0037] The lure 1A shown in FIG. 7 is a device in which the front body 2 and the rear body 3 are more firmly connected. The front body 2 is provided with a hole h in the left-right direction, and the rear body 3 is fixed to the front body 2 without moving by inserting the pin 10 through the rear body 3 and the hole h. The pin 10 is held by the elasticity of the rear body 3. Also, the direction of the hole h may be the vertical direction instead of the left-right direction.

[0038] Hereinafter, with reference to the drawings, the lure 1B of the second embodiment of the present invention will be described.

[0039] As shown in FIGS. 9, 10, and 11, the lure 1B is an example in which the ratio of the rear body in the entire body is larger than that of the lure 1A, and a treble hook is attached. (It is a type of lure generally called a swim bait.) Similar to the lure 1A, the material of the rear body 3 of the lure 1B is also a soft material. Although most of the lure body is made of a soft material, the weight 4 can move inside the soft material part. The explanation of the symbols is the same as that of the lure 1A.

[0040] As shown in FIGS. 9, 10, and 11, the front body 2 of the lure 1B includes an eight-ring 8a for locking the fishing line and an eight-ring 8b for locking the fishing hook 6, and each eight-ring functions as a line eye and a hook eye. The manufacturing method of the front body 2 is the same as that of the lure 1A, and the front body 2 is assembled by combining the left and right members. When combining the left and right members, the eight-ring 8 is fixed to the front body 2 by sandwiching each eight-ring between the left and right members. Conventional lures made of soft materials could not sandwich the eight-ring and fix the eight-ring to the body, so it was necessary to incorporate a wire or the like inside to provide a hook eye or a line eye. Lures equipped with a hook eye or a line eye (generally called a swim bait) had a problem of high manufacturing cost. However, since the front body 2 of the lure 1B can be manufactured from the same material and manufacturing method as a general hard lure, a hook eye or a line eye can be provided by the eight-ring in the same way as a general hard lure, and it can be manufactured at a low cost.

[0041] In the lure 1B of the second embodiment of the present invention, two fishing hooks 6 called triple treble hooks are provided, and the rear fishing hook 6 is locked to the eight-ring 8a via a wire 9, and the rear fishing hook is pierced into the body. However, the shape and number of the fishing hooks are not necessarily limited to the above.

[0042] As shown in FIGS. 9, 10, and 11, the front body 2 of the lure 1B is provided with a lip 7. The lip 7 is integrally formed with the front body 2. Since the lip needs to be formed of a hard material, conventional soft-material lures cannot integrally form the lip with the body, and there are problems with the bonding strength between the lip and the body. However, since the material of the front body 2 is hard plastic and can be manufactured by the same manufacturing method as a general hard lure, the front body 2 and the lip 7 can be integrally formed in the same manner as a general hard lure, so the bonding strength between the lip and the body is excellent.
