Description

The present invention relates to fishing lures called hard baits or hard lures containing plugs.

A hard lure is formed by attaching a fish hook to a hard lure body made of synthetic resin, wood, metal, or the like. However, the term "hard" or "hard" used in the present application has a broader meaning than the hardness of hard lures that are generally said. That is, even if a material called an elastomer is used as the material of the lure body, it may be included in the term "rigidity" of the present application. In short, it is sufficient that the overall shape of the lure body is maintained during fishing, meaning that only lures (soft lures) whose shape can be freely changed during fishing are excluded. Examples of such hard lures are disclosed in Patent Documents 1 and 2, Non-Patent Document 1, etc., filed by the present applicant. In general, fishing lures may get snagged or rub against rocks, stones, etc. during use, resulting in damage to the tip of the hook or damage to the bent portion of the hook. In the lure of Non-Patent Document 1 below, since the hook is integrated with the lure main body, if the hook is damaged, it cannot be replaced, and the lure itself must be replaced. The hooks of the lures disclosed in Patent Documents 1 and 2 of the present applicant can be replaced.

In the fishing lure disclosed in Patent Document 1, although the hook can be replaced, there is a problem that the hook tends to separate from the lure body unintentionally during fishing.
In the fishing lure of Patent Document 2, the hook can be replaced, and the hook does not come off from the lure body during fishing. be.
Therefore, the problem to be solved is that the lure body and the fishhook can be separated and the fishhook can be replaced, and the fishhook does not come off carelessly from the lure body during use, and the fishinghook is extremely easy to attach to the lure body. It is the provision of fishing lures that are

In view of the above problems, the first invention is a fishing lure in which a hard lure body and a fishhook are set,
The fishhook has a shaft portion extending in the front-rear direction, a bent portion that is continuous with the shaft portion and is bent with respect to the extending direction of the shaft portion, and a fishing line insertion hole at the front end of the shaft portion. a head portion larger than the shaft portion, and a needle tip provided at the tip of the bent portion;
The lure body is provided with a front side port that opens to the front side region of the lure body, and the range excluding the rear region of the lure body from the front side port is not exposed on the surface of the lure body and penetrates inside. and a fishhook insertion passage extending to a rear side opening opened at the rear end of the lure body, the fishhook insertion passage having a diameter large enough to allow the head of the fishhook to be inserted, and the shaft characterized by having a length equal to or less than the length of the portion.

In a second aspect of the invention, the fishhook is provided near the front opening of the lure body, and the hook is installed in a state in which the plane including the bent portion of the fishhook extends vertically with respect to the lure body. extends or spreads in a direction substantially orthogonal to the insertion direction of the fishing line insertion hole provided in the head of the head, and is provided in contact with or close to the head, along the insertion direction It is characterized by comprising a fish hook detent having a penetrating lure main body side hole.

A third aspect of the invention is provided on the top side or the bottom side in the rear region of the lure body in communication with the rear side port, and in a state where the fishhook is incorporated in the fishhook insertion passage, the base of the bent portion is It is characterized in that a slit that can be pinched is provided along the front-rear direction of the lure body.

According to a fourth aspect of the present invention, the cross-sectional shape of at least a region near the front side opening of the fishhook insertion passage is non-circular in cross section having a long axis direction and a short axis direction, and the fishhook passage in the long axis direction. The dimension is equal to or larger than the maximum diameter of the head of the fishhook, and the dimension of the fishhook insertion passage in the minor axis direction is smaller than the maximum diameter.

In a fifth aspect of the invention, the lure body has a substantially flat plate-shaped upper surface portion and a substantially flat plate-shaped lower surface portion positioned below the upper surface portion, and the upper surface portion and the lower surface portion are arranged on the left and right sides, respectively. They are connected to each other by a connecting wall in the central part of the direction, the left wall surface of the connecting wall extending in the rear left direction in the rear part of the lure body, and the right wall surface of the connecting wall extending in the rear right direction in the rear part It is characterized by

In the first invention, the lure body is provided with a front mouth portion that opens to the front region of the lure body, and the lure body is in a range excluding the rear region of the lure body on the rear side from the front mouth portion. It has a fishhook insertion passage that penetrates through the inside without being exposed on the surface and reaches the rear opening that is open at the rear end of the lure body, and the head of the fishhook can be inserted through the fishhook insertion passage. Since it has a large passage diameter and a length equal to or less than the length of the shaft, the fishhook can be easily assembled to the lure body by inserting the head of the fishhook from the rear mouth of the lure body. can be done. In addition, by inserting a snap or a fishing line into the fishing line insertion hole in the head protruding from the front mouth of the lure body, fishing with the lure can be enjoyed, and the hook will not come off the lure body carelessly. Furthermore, if necessary, the hook can be easily removed by pulling it backward from the lure body, and can be replaced with a new hook.

In the second invention, in a state in which the fishhook is assembled in such a posture that the plane including the bent portion of the fishhook spreads vertically with respect to the lure body, the fishing line is roughly inserted in the direction of insertion of the fishline insertion hole provided in the head of the fishhook. Since the hook rotation stopper extending or spreading in the orthogonal direction is provided, the hook incorporated in the lure body can be prevented from rotating around its own axis, and lure fishing can be performed in a stable state. can. In addition, since the lure main body side hole penetrates along the insertion direction of the fishing line insertion hole, the snap and the fishing line can be passed through the fishing line insertion hole of the fishhook head and the lure main body side hole. It is possible to further ensure that the fish hook is pulled out of the lure body to the rear.

In the third invention, since the slit sandwiching the base of the bent portion is provided along the front-rear direction of the lure body, it is possible to effectively prevent the fishhook attached to the lure body from rotating around its own axis, Lure fishing is possible in a stable state.

Since it is smaller than the maximum diameter of the head, the fishhook can be inserted by aligning the maximum diameter of the head with the longitudinal direction and pushing it in. After insertion, the hook is rotated around its axis so that the maximum diameter direction of the hook head is aligned with the short axis direction. In this state, the hook is prevented from coming off backward, and lure fishing can be stably performed. .

In the fifth invention, according to fishing experiments, when this fishing lure is pulled by a fishing line, it makes interesting side-to-side movements stably, like a living underwater insect moving. The left and right movement is considered to be mainly due to the shape of the left and right wall surfaces of the connecting wall spreading left and right at the rear part, and the stable swimming is mainly due to the existence of the flat upper and lower parts. thinking.

The invention will now be described in more detail with reference to the accompanying drawings. An example of a hook 10 for use with a fishing lure according to the present invention is shown in FIG. A head portion 10T, also called an eye, is formed at one end of the shaft portion 10J, and a bent portion 10M is provided at the other end. This fishhook 10 is not provided with an engaging portion (barb portion) for preventing the fish from escaping when it is hooked, but may be provided. Further, the head 10T is formed with a fishing line insertion hole so that the fishing line can be inserted along a direction parallel to a plane including the (shaft portion 1OJ) and the bent portion 10M. The head portion 10T is made into a ring shape by bending the material of the shaft portion, but the way of making it is arbitrary. A center line TC indicates the center position and insertion direction of the fishing line insertion hole. That is, the head portion 10T expands in a direction substantially perpendicular to the plane formed by the shaft portion 10J and the bent portion 10M. However, the head is formed in a form that spreads along a plane substantially parallel to the plane formed by the shaft portion 10J and the bend portion 10M, and the fishing line extends in a direction substantially orthogonal to the plane formed by the shaft portion 10J and the bend portion 10M. can be inserted. That is, the head may be formed so as to have a fishing line insertion hole through which the fishing line is inserted in a direction penetrating the plane of FIG.

Referring to FIGS. 2 and 3, the lure body 20 has a front half, that is, a rear region narrower than the front region in plan view, and the width becomes narrower toward the rear. It has a spindle shape. In addition, the upper surface 20A of the lure main body in a side view has a smoothly convex curved surface shape, but the lower surface 20B has a planar shape. However, the front end region of the lower surface is inclined upward to the front. A plate extending in the vertical direction may be provided in the center of the front end region in the horizontal direction. This is related to lure protection and swimming stability. To protect the tip of the lure body 20, a method such as covering the tip with an aluminum plate member can be employed.

A front side opening FP is provided in the front region of the lure body 20 . Here, referring to FIG. 4, this front side port FP communicates with the fishhook insertion passage TR. It extends to the rear side port RP opened at the rear end of the . A slit SL communicating with the rear side port RT is formed on the upper surface 20A side. In this embodiment, the slit SL is provided along the front-rear direction only on the upper surface side of the rear region of the lure body 20 . That is, the fishhook insertion path TR is exposed on the surface of the lure main body 20 at the front side opening FP and the rear side opening RP. It is not exposed on the surface of the main body 20 at all. In this embodiment, the lure body 20 is closed over its entire length on the lower surface 20B side. At least there is no opening that communicates with the needle insertion path TR. On the upper surface 20A side, there is no opening communicating with the fishhook insertion passage TR over the entire length except for the slit SL. Note that the recess HK described below only communicates with the front side port FP. In addition, the lure body 20 immediately in front of the front side mouth FP has a recess HK dug down to an appropriate depth. This is a recess provided for the work of attaching a fishing line or a snap to the fishing line insertion hole of the head 10T of the fishhook 10. As shown in FIG.

Furthermore, in this embodiment, a fish hook rotation stop KS is provided by a semi-annular metal ring positioned immediately above the front port FP. As shown in FIGS. 2 and 4, this fishhook rotation stop KS is provided with a lure body side hole SH, and this semi-annular fishhook rotation stop KS extends in the penetrating direction SC of the lure body side hole SH. Spread along orthogonal planes. Further, as shown in FIG. 4, the extending direction of the fishhook rotation stop KS in a side view is along the extending direction of the fishhook insertion passage TR. The fishhook rotation stop KS is not limited to a semi-circular shape, and may have any shape as long as it has a width (width) as a rotation stop.

In order to incorporate the fishhook 10 into the lure body 20, the head 10T of the fishhook 10 is inserted from the rear port RP of the lure body 20 into the fishhook insertion passage TR to expose the head 10T from the front port FP. That is, the length of the fishhook insertion passage TR is set to be equal to or less than the length of the shaft portion 10J of the fishhook 10. As shown in FIG. In this embodiment, the cross-sectional shape of the fishhook insertion passage TR has a long dimension L1 in the horizontal direction (major axis direction) and a short dimension L2 in the vertical direction (minor axis direction), as shown in FIG. It has an oval shape and a non-circular cross-section. Further, in this embodiment, the fishhook insertion passage TR is formed of a metal pipe P such as stainless steel. Of course, it may be formed directly on the material of the lure body 20 . The major axis dimension L1 is greater than or equal to the maximum diameter of the head 10T of the fishhook 10, and the minor axis dimension L2 is smaller than the maximum diameter but greater than or equal to the diameter of the shaft portion 10J.

Therefore, when inserting the head portion 10T of the fishhook 10 into the fishhook insertion passage TR, the bent portion 10M of the fishhook should be oriented as indicated by the two-dot chain line in FIG. The fishing hook 10 is pushed into the lure main body 20 in a vertically oriented posture. That is, the head 10T of the fishhook 10 spreads in the direction orthogonal to the plane of FIG. 1, but since the direction of spread is the horizontal direction in FIG. 6, it can be inserted in that posture. Then, the base of the bending portion 10M is pushed into the slit SL. In this state, the head 10T of the fishhook 10 is in the state shown in FIG. That is, the spread plane of the head 10T is (approximately) parallel to the spread plane of the hook rotation stop KS. A fishhook rotation stopper KS is provided at a position where the head 10T and the fishhook rotation stopper KS come close to each other in the vertical direction or come into contact with each other.

The close arrangement of head 10T and hook detent KS prevents rotation of hook 10 about its axis. The same rotation is also prevented by the engagement of the base of the bent portion 10M of the fishhook 10 with the slit SL. Only one of these two constituent requirements, ie, the proximity configuration and the slit SL, may be used. Further, a pair of upper and lower fishhook rotation stoppers KS may be provided so that the head 10T of the fishhook 10 is sandwiched between the pair.
A fishing line or a snap is used by being passed through both the hook rotation stop KS and the head 10T of the hook 10. - 特許庁

In the case where the fishhook rotation stop KS is not provided, the head 10T of the fishhook 10 shown in FIG. In the case of the form along the plane including the bent portion, the non-circular cross-sectional area in FIG. 6, which is the enlarged cross section of the hook insertion passage TR, is not the entire hook insertion passage TR, but only the area near the front side opening FP. It is also possible to provide a form in which That is, the vertical direction is the minor axis direction only in this area. In this case, when the hook 10 is incorporated into the lure body 20 and set to the state of the bent portion 10M shown in FIG. That is, the spread of the head 10T becomes a posture in which it spreads not only in the front-rear direction but also in the vertical direction. At this time, since the base of the bent portion 10M is engaged with the slit SL, the rotation of the fishhook 10 around the axis is prevented. Also, in this state, the hook 10 is prevented from slipping backward. This is because the vertical dimension of the head 10T is larger than the minor axis dimension L2, which is the vertical dimension of the fishhook insertion passage TR. Needless to say, the range of the non-circular cross section of the fishhook insertion passage TR shown in FIG. 6 may be provided over the entire length of the fishhook insertion passage TR.

When the head portion 10T of the fishhook 10 in the configuration shown in FIG. 5 is rotated 90 degrees with respect to the drawing plane of FIG. 5, that is, along the drawing plane of FIG. It will be provided so as to have a wide spread. This prevents the fishhook 10 from rotating. It is the same as in the case of the first embodiment that the fish hook rotation stoppers KS may be provided on the left and right sides of the pair of head parts 10T. Furthermore, when the cross section of the fishhook insertion passage TR is non-circular, it is not limited to an oval shape, but may be an ellipse shape. It suffices if there is a direction and a minor axis direction. In the broadest case (first invention) of the present invention, the cross section of the fishhook insertion passage TR may be circular, and the head 10T may pass through it.

Next, a case where the lure body 20 differs from the above forms will be described. 7 is a view of the lure body 30 viewed from above, and FIG. 8 is a front view viewed from the arrow line H in FIG. The lure main body 30 has an upper surface portion UP and a lower surface portion LP facing each other in the vertical direction, and is connected by a connecting wall RH. Although the upper surface UP and lower surface LP are generally parallel embodiments, the front of the upper surface UP may be angled further away from the lower surface LP than the rear. Further, the front view shape of the outer surface of the upper surface portion UP may be substantially V-shaped (including U-shaped) with an angle close to a plane (large opening angle). The connecting wall RH is provided at the central portion of the lure body 30 in the left-right direction.

A front side opening FP is opened in the front region of the upper surface portion UP, and a rear side opening RP is opened in the rear end portion of the lure body 30, and a fishhook insertion path TR extends from the rear side opening RP to the front side opening FP. It is provided in a straight line. The top part UP is provided with a hole HK' in the area immediately in front of the front side opening FP. It is for work when inserting snaps and fishing line. A slit SL communicating with the fishhook insertion passage TR and the rear side port RP is provided at the rear end portion of the upper surface portion UP. Immediately above the front side opening FP, a fishhook rotation stopper KS extends along the extension direction of the fishhook insertion passage TR and spreads in the left-right direction. The fish hook rotation stopper KS is provided with a lure main body side hole SH.

In relation to the shape of the fishhook 10, deformations such as the presence or absence of the hook rotation stopper KS and the setting direction are the same as in the case of the lure body 20, but the shape of the hook rotation stopper KS extends in the left-right direction. A linear member such as a metal may be used. In this case, the plate-like fishhook rotation stop KS in FIG. 7 is eliminated, and the space between the rear edge of the hole HK' and the linear member becomes the lure main body side hole. That is, the lure body side hole is defined by the rear edge of the hole HK' (the rear edge, and the left and right edges of the rear region of the hole HK') and the linear member.
The upper end of the front end of the connecting wall RH is positioned on the rear side near the lure main body side hole SH, and the lateral width is a narrow width that is about a fraction of the width of the lure main body 30 (or the upper surface portion UP). However, it has a narrow width portion extending to the rear while generally maintaining the same width, and the width smoothly expands in the rear portion. That is, the right wall surface RS of the connecting wall RH extends rearward along the front-rear direction of the lure body 30, smoothly continues to the right wall surface RS in the rear portion, and extends in the rear right direction to the right side of the upper surface portion UP and the lower surface portion LP. It's getting to the edge. The left wall surface LS is formed substantially bilaterally symmetrical to the right wall surface RS with respect to a center line passing through the center of the lateral width of the lure body 30 . Regarding the position in the front-rear direction, the portion of the front end of the connecting wall RH excluding the upper end is arbitrary and may be at the same position as the upper end. It may be formed in an inclined shape toward the part.

INDUSTRIAL APPLICABILITY The present invention can be used for fishing lures called hard lures. In particular, it can be used effectively when a damaged hook can be replaced and the lure body can be used repeatedly.
