Description

[Technical Field]

[0001] The present disclosure relates to fishing lures. [Background technology]

[0002] Large fish such as smallmouth bass, largemouth bass, catfish, and sea bass feed on fish and small animals such as earthworms, shrimp, crayfish, frogs, insects, and mice as bait. Lure fishing is a popular method of catching these large fish. In lure fishing, a lure is used. A fishing line is attached to the lure. The lure flies through the air when cast and eventually hits the water. The lure swims underwater or on the surface of the water as the fishing line is wound around it. The fish mistake the lure for bait and bite the lure. The hook attached to the lure pierces the fish, and the fish is reeled in.

[0003] Conventionally, there are lures called hard lures, which are made of hard materials such as plastic, wood, and metal, and these hard lures generally have a hook attached to the lure body with the entire hook exposed to the outside (Figure 1 of Patent Document 1).

[0004] Therefore, when hard lures are used around obstacles such as underwater trees, rocks, or the bottom of the water, where fish are generally likely to be hiding, there is a problem in that the fishing hook is likely to get caught on the obstacles.

[0005] As an example of a hard lure that is less likely to have the hook caught on the above-mentioned obstacles, Patent Document 2 discloses, for example, in Figure 1 etc., a lure in which the front and rear bodies of the lure are connected so that they can slide relative to each other, the fishhook attached to the front body is hidden in a groove in the rear body, and when a fish bites, the front and rear bodies slide together, causing the fishhook to protrude from the groove in the rear body.

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2022-176045 Patent Document 2: Patent No. 7569469 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the lure disclosed in Patent Document 3 succeeds in increasing the amount of hook protrusion by connecting the front body and the rear body only with an elastic member after the front body and the rear body have slid to their limit, but has the problem that the front body and the rear body can unintentionally separate when casting.

[0008] Therefore, the present disclosure provides a lure in which the front and rear bodies of the lure are connected so as to be slidable relative to one another, the fishhook attached to the front body is hidden in a groove in the rear body, the elastic member for keeping the fishhook hidden can be easily replaced, the front and rear bodies can be freely fitted and detached from each other, the front and rear bodies do not separate unintentionally when cast while ensuring a sufficient amount of protrusion of the fishhook, and in addition, the lure has a texture closer to that of a real bait. [Means for solving the problem]

[0009] A lure according to an example of the present disclosure includes a front body having a fishhook and a rear body having a groove, the groove of the rear body concealing at least a portion of the fishhook, The front body and the rear body have a curved, slidably connected portion, and when the front body and the rear body slide together, the fishhook protrudes from the groove of the rear body.

[0010] In the lure that is one example of the present disclosure, the front body and the rear body may include a portion that is linearly and slidably connected.

[0011] In the lure that is one example of the present disclosure, the front body and the rear body may slide linearly and then slide in a curved manner, so that the fishhook protrudes from the rear body.

[0012] In the lure that is one example of the present disclosure, the rear body may slide relative to the rear body in a direction rotating around the front body at the curved, slidably connected portion.

[0013] In a lure that is an example of the present disclosure, either the front body or the rear body may have a linearly protruding ridge, and the other may be slidable along the ridge.

[0014] In the lure according to one example of the present disclosure, the fishhook may be fixed to the front body without moving relative to the front body, and the rear body may be slidable relative to the fishhook.

[0015] In a lure that is an example of the present disclosure, the front body has a line eye to which a fishing line or a snap, split ring, or the like that articulately connects the fishing line is engaged, the front body does not have a movable part between the line eye and the tip of the fishhook, the fishhook is fixed to the front body without moving relative to the line eye, and the rear body may be slidable relative to the fishhook.

[0016] In the lure that is one example of the present disclosure, when the fishhook protrudes from the groove, it may protrude from the hook tip. [Effects of the Invention]

[0017] The lure according to the present disclosure can, for example, prevent itself from getting caught on underwater obstacles. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] The lure 1 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 16. In each drawing, the scale of each component may be changed as needed to make each component large enough to be visible.

[0020] As shown in Figures 1, 2, and 3, the lure 1 of this embodiment is used for fishing and is an example of a lure that resembles the shape of a small fish and is formed by combining hard plastic members and flexible members.

[0021] Here, in the lure 1, the direction in which the lure moves when reeling is defined as the forward direction, and the front-to-back direction of the lure is defined as the up-down direction in the posture when reeling, and the lateral direction perpendicular to the front-to-back direction when viewed from above is defined as the left-to-right direction in the following description.

[0022] Below, we will explain the functions and configuration of Lure 1.

[0023] As shown in Figures 1, 2, and 3, lure 1 comprises a front body 2, a rear body 3, a flexible member 4, and an elastic member 5. The flexible member is attached to cover the rear body, and the front body is composed of a head portion 2a molded from resin and a fishhook portion 2b formed from a linear metal. The front body and the rear body are connected, and the elastic member is attached to the front body and the rear body. The rear body has a groove portion 3a, and at least a part of the fishhook portion is hidden in the groove portion 3a.

[0024] The front body is provided with a line eye 2c, to which a fishing line or a snap, split ring or the like that articulates the fishing line is fastened, and the lure 1 swims when the fastened fishing line is pulled.

[0025] The front body and the rear body are connected so as to be slidable relative to each other. The elastic member urges the portion of the front body to which the elastic member is attached and the portion of the rear body to which the elastic member is attached toward each other, so that when no large external force is applied to the lure 1 (such as during reeling or storage), the fishhook portion remains hidden in the groove 3a of the rear body as shown in Figures 1 and 2 (fishhook hidden state). When a fish bites the lure 1 and pulls the fishing line, the elastic member elastically deforms (stretches), causing the front body and the rear body to slide relative to each other, causing the fishhook attached to the front body to protrude from the hook tip 2h out of the groove 3a (fishhook protruding state), pierce the fish, and the fish can be reeled in.

[0026] The structure for connecting the front body and the rear body will now be described.

[0027] As shown in Fig. 4, the front body has a pair of ridges 2d that protrude linearly in the left-right direction, and as shown in Fig. 5, the rear body has a pair of protruding folds 3b on the left and right, with the right fold protruding leftward and the left fold protruding rightward, and as shown in Fig. 6, the folds slide along the ridges, thereby slidably connecting the front body and the rear body to each other. Hereinafter, the relative sliding of the front body and the rear body due to the folds sliding along the ridges will be referred to as S.

[0028] As shown in Figures 4 and 7, recesses 2e are provided at the ends of the ridges of the front body, and the recesses 2e have a smaller width in the left-right direction than the other portions of the ridges. As indicated by arrows F in Figures 8 and 9, the folds can pass through the ridges in a direction from the recesses to straddle the ridges. The left-right distance between the closest folds (k1 in Figure 6) is set larger than the left-right width of the recesses (k2 in Figure 7). Alternatively, the left-right widths of the folds (k1 in Figure 6) and the left-right widths of the recesses (k2 in Figure 7) are set within a range such that the folds can bend left and right as they pass through the recesses, thereby widening the left-right width of the folds (k1 in Figure 6).

[0029] In the lure 1, the recessed portions are provided at the ends of the ridges, but as long as the folds can pass through the recessed portions, they may be provided at offset locations of the ridges. Also, as long as the folds can pass through the ridges in a direction spanning the ridges, the recessed portions do not have to have a shape in which a portion of the ridge is recessed, as in the case of the recessed portions described above.

[0030] As shown in Fig. 10, the front portion of the flexible member 4 includes two shell-shaped portions 4a, one on each side, and bridging portions 4w, 4x, 4y, and 4g that bridge the left and right shell-shaped portions. The left shell-shaped portion bulges leftward, and the right shell-shaped portion bulges rightward, forming a hollow portion 4b surrounded by the left and right shell-shaped portions and the bridging portions. The flexible member is attached to the rear body by inserting the rear body into the hollow portion. Also, as shown in Fig. 5, the rear body includes groove-shaped recesses 3w, 3x, 3y, and 3g. As shown in Fig. 11, 4w fits into 3w, 4x fits into 3x, 4y fits into 3y, and 4g fits into 3g. The flexible member is removably fixed to the rear body by elastically deforming and inserting each bridging portion into each recess.

[0031] Although lure 1 has two shell-shaped portions, it may have three or more portions.

[0032] 12, when S is performed with the flexible member attached to the rear body, the bridge portion 4w inserted into the recess 3w abuts against the fishhook portion, shortening the distance that the fold portion can slide along the ridge compared to when the flexible member is not attached to the rear body, and the position of the fold portion does not reach a position where it can pass through the recess. In other words, after the front body and the rear body are connected, by attaching the flexible member to the rear body (inserting the bridge portion 4w into the recess 3w), the fold portion cannot pass through the recess, and therefore the front body and the rear body do not separate during S.

[0033] In addition, when S is performed due to the impact of casting or hooking, the bridge portion 4w abuts against the hook portion, which has the effect of mitigating the impact when the front body and the rear body collide.

[0034] In the lure 1, the bridge portion 4w abuts against the hook portion when the lure 1 is in the S position, but it is not necessary for the bridge portion 4w to abut against the hook portion, and it is sufficient if a part of the flexible member abuts against a part of the front body.

[0035] The shape of the flexible member will be described in detail below.

[0036] As shown in Figure 5, the recess has a narrow width portion k where the groove width is narrower and a wide width portion j where the groove width is wider than the narrow width portion, and the wide width portion is located closer to the groove bottom i than the narrow width portion. When attaching the flexible member to the rear body, the bridge portions are elastically deformed and the flexible member is inserted through the narrow width portion k, thereby fixing the flexible member to the rear body.

[0037] As shown in Fig. 10, the flexible member has a slit 4c, which conceals a part of the hook portion as shown in Fig. 13. Also, a stopper 4d protruding toward the inside of the slit may be provided as shown in Fig. 14. The hook portion and the stopper come into contact with each other to provide resistance, so that the front body and the rear body do not slide with a force below a certain level, preventing the front body and the rear body from sliding unintentionally except when hooking (such as during casting).

[0038] As shown in Figure 10, the rear part of the flexible member is provided with a bellows part 4e. The bellows part allows the lure 1 to swim more like a real fish when reeling, and the flexible deformation of the bellows part reduces the hindrance to hooking caused by contact between the flexible member and the fish.

[0039] When the flexible member is attached to the rear body, the shell-shaped portion covers a portion of the flexible member.

[0040] The structure of the rear body will now be described in more detail.

[0041] As shown in Figures 15 and 16, the rear body has a pair of buoyant bodies 3c on the left and right, which are hollow portions filled with air.

[0042] As shown in FIG. 16, the rear body is provided with a pair of weights 3d on the left and right.

[0043] The buoyant body and the sinker enable the lure 1 to swim stably.

[0044] The structure of the front body will now be described in more detail.

[0045] 4, the ridges of the front body include curved portions 2f that are curved in the front-rear and up-down directions and straight portions 2g that are not curved, and the curved portions 2f are curved in an arc shape centered on the front body, so that when S is performed at the curved portions 2f, the rear body slides in a curved manner relative to the front body. Also, when S is performed at the straight portions 2g, the rear body slides in a straight manner relative to the front body.

[0046] As the front body and the rear body slide and the fishhook protrudes from the groove to the outside of the rear body, the fold slides over the straight portion 2g and then over the curved portion 2f, causing the rear body to slide linearly (indicated by arrow N in FIG. 12) and then curvedly (indicated by arrow M in FIG. 12) relative to the front body. By first sliding linearly (indicated by arrow N in FIG. 12), the force pulling the fishing line during hooking is efficiently converted into a force that protrudes the hook, allowing the tip of the hook to pierce the fish more reliably. Then, by sliding curvedly relative to the front body in a direction rotating around the front body (indicated by arrow M in FIG. 12), the fishhook protrudes more, allowing the inserted hook to pierce the fish more deeply.

[0047] 5, in lure 1, the portion where the fold portion meets the ridge is generally arc-shaped so that the fold portion can slide smoothly along the curved portion 2f of the ridge, but the portion where the fold portion meets the ridge may be a generally elliptical arc or some other curved shape. Also, in lure 1, the front body is provided with ridges, but the rear body may also be provided with ridges, and a portion of the front body that can slide along the ridges may be provided, so that the front body and rear body are slidably connected.

[0048] As shown in Figure 4, the front body does not have any joints or movable parts from the line eye to the hook tip, and the fishhook is fixed without moving relative to the front body and the line eye. The fishhook does not slide relative to the front body or the line eye to protrude from the rear body, but the rear body slides and moves relative to the fishhook, causing the fishhook to protrude from the rear body. This structure allows the pulling force on the fishing line at the time of hooking to be transmitted to the hook tip without attenuation, allowing the fish to be more reliably pierced with the hook.

[0049] In the lure 1, the flexible member 4 and the elastic member 5 are made of soft rubber, gel, or soft resin. (1) Soft rubber Examples of soft rubber 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 examples of thermoplastic elastomers (TPEs) include styrene-based TPEs, olefin-based TPEs, vinyl chloride-based TPEs, urethane-based TPEs, ester-based TPEs, amide-based TPEs, chlorinated polyethylene-based TPEs, Syn-1,2-polybutadiene-based TPEs, Trans-1,4 polyisoprene-based TPEs, and fluorine-based TPEs. (2) Gel Examples of gels include silicone gel and acrylic resin gel. (3) Soft resin Examples of soft resins include vinyl chloride resins and polyolefins.

[0050] The lure 1 of this embodiment has a shape that resembles a fish, but the shape does not necessarily have to resemble a fish, and may be, for example, an insect or a crustacean. [Explanation of symbols]
