Description

  The present invention relates to a jig head used for fishing.

  In recent years, lure fishing has been actively performed in the sea. Lures are broadly divided into hard lures and soft lures.

  Examples of hard lures include minnows, crank baits, pencils, hoppers, and vibrations. They have realistic fish shapes, patterns, and colors, and can reproduce a variety of movements (actions) according to the shape and mechanism.

  Examples of soft lures include Texas rigs and jig head rigs. A rig is a device for using a soft soft worm (hereinafter referred to as “worm”) which is an elastic body.

  The Texas rig has a hook and sinker separate from each other. After passing the sinker (thread) through the thread, the end of the thread is tied to the eye of the offset hook, and the worm is replaced by the offset hook. Can be attached freely.

  On the other hand, the jig head rig has a hook and sinker integrated (the integrated unit is called “jig head”), a spherical shape (see FIG. 7 or the drawings published in Patent Document 1), a football shape, and a fish A hook (often a straight hook) is fixed to a sinker having a shape imitating only the head, and a worm is removably attached to this hook. In general, a straight hook is said to be easily hooked on the other hand because the needle tip penetrates the worm and comes out on the outer surface (see the drawings described in Patent Document 1).

  By the way, fish with a large mouth try to swallow the bait fish from behind, but they usually attack the bait fish's eyes and fins to damage and weaken it to some extent, and then try to supplement it. Therefore, the worm is subject to an attack (load) by the target fish from various directions, and therefore, there is a problem that the worm is easily displaced from a predetermined position.

  Although it depends on how the worm is attached, in general, in the case of a straight hook, the worm is inserted into the shank part of the hook that extends straight, so the attack from the side, that is, the attack from the side toward the abdomen of the worm Even if there is, it is difficult to shift from the predetermined position, but when the tail of the worm is bitten and the worm is pulled backward, it is easy to shift from the predetermined position. On the other hand, in the case of an offset hook, the worm is mounted so as to be bridged between the bent offset crank portion and the needle tip, so that even when the offset crank portion is caught and the worm is pulled backward, it is predetermined. However, when a lateral attack (attack to the side of the worm) is received, a torsional force is applied to the worm and the positional deviation is likely to occur (see FIG. 7). FIG. 7 shows a state in which a torsional force is applied to the worm 100 when the attack from the lateral direction (attack to the side of the worm) is applied, and the forehead of the worm 100 is detached from the offset crank portion 101. .

  If the worm deviates from the predetermined position, the way of swimming becomes unnatural, and even if the fish bites, it may not be hooked. Therefore, it is preferable that the worm attached to the jig head does not deviate from a predetermined position even when there is a fish bite or root.

Japanese Patent No. 3749006

  Conventional sinkers of jig heads are mainly in the shape of a simple shape such as a spherical shape (see FIG. 7 or the drawings published in Patent Document 1), a football shape, and a shape imitating only the head of a fish. For this reason, it has been difficult to reproduce various movements (actions), and the movements also lacked realism. As a result, there was a problem that the fun of lure fishing was poor and the fish bite was poor.

  It is thought that the fish distinguishes the dorsal and ventral sides of the fish that are trying to prey by color differences. Therefore, improvement in fishing results can be expected if the back and abdomen of the fish can be expressed by painting, but the conventional jig head uses a simple shape sinker such as a spherical shape, a football shape, or a shape imitating only the fish head. Since there is no portion corresponding to the back or abdomen of fish, the back and abdomen could not be expressed by painting.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a jig head capable of reproducing a plurality of actions and having a high appealing force against a target fish.

  The jig head of the present invention is a jig head having a hook to which a worm can be replaced, and a sinker to which the hook is fixed, and a ventral-side extension extending rearward is provided on the bottom of the sinker, The sinker is provided with a back-side extension extending rearward on the water surface side, and the back-side extension is provided with an annular eye.

  Furthermore, the jig head of the present invention may arbitrarily set the lateral width of the abdominal extension part larger than the lateral width of the back extension part.

  Further, in the jig head of the present invention, the hook may optionally be a straight hook, and a return portion may be formed upward at an end portion of the ventral extension portion.

  Furthermore, in the jig head of the present invention, an eye to which an assist hook is detachably attached is optionally provided on the bottom side of the sinker, and the assist hook can be fitted to the ventral extension portion. A fin having a plurality of groove portions may be provided.

  Furthermore, in the jig head of the present invention, the hook may optionally be an offset hook, and the ventral extension may be formed toward the offset crank portion of the offset hook.

  According to the present invention, it is possible to reproduce a plurality of movements (actions) with one jig head, so that the pleasure of lure fishing increases, and by selecting an appropriate movement (action) according to the target fish, Fish bite is also improved.

  According to the present invention, optionally, the hook is a straight hook, and a return portion is formed upward at the end of the abdomen-side extension portion. It is also possible to reduce the height of the worm, and thus it is possible to mount the worm so that the tail of the worm hangs downward. According to the present invention, optionally, the hook is an offset hook, and the abdomen extension is formed toward the offset crank, thereby reducing the displacement of the worm in the offset hook type jig head. It is also possible.

It is a side view of the straight hook type jig head which is one embodiment of the present invention. It is a rear view of the jig head shown in FIG. It is a bottom view of the jig head shown in FIG. FIG. 2 is an explanatory diagram of a state in which a worm is attached to the jig head shown in FIG. It is a side view of the offset hook type jig head which is other embodiments of the present invention. FIG. 6 is an enlarged view around the offset crank portion of the jig head shown in FIG. 5. It is a side view of the conventional offset hook type jig head.

  Hereinafter, a jig head 1 according to an embodiment of the present invention will be described. 1 is a side view of a straight hook type jig head 1 according to an embodiment of the present invention, FIG. 2 is a rear view of the jig head 1 shown in FIG. 1, and FIG. 3 is a jig head shown in FIG. 1 is a bottom view of FIG.

  As shown in FIG. 1, the jig head 1 includes a sinker 2 that serves as a weight, and a straight hook 3 fixed to the sinker 2. A soft resin worm (not shown) which is an elastic body is attached to the straight hook 3 so as to be replaceable. The sinker 2 is processed to simulate the mouth and eyes of a fish, and annular eyes 10 and 11 are attached to the mouth and the upper part of the eyes.

  A ventral side extension 4 extending rearward is provided on the water bottom side of the sinker 2, and a back side extension 5 extending rearward is provided on the water surface side of the sinker 2. The abdominal extension 4 is provided to extend rearward from the bottom of the sinker 2 so as to constitute a part of the abdomen of the lure when viewed with the worm attached. The back extension 5 is provided so as to extend rearward from the water surface side of the sinker 2 so as to form a part of the back of the lure when viewed with the worm attached.

  In the present embodiment, in the sinker 2, the sinker body 2a to which the straight hook 3 is fixed, the abdominal extension 4 and the back extension 5 are integrally molded from the same material. Of course, although not shown, the sinker to which the hook is fixed, the abdominal extension provided to extend backward on the bottom of the sinker, and the back extension provided to extend rearward on the water surface side of the sinker are different materials. Then, the abdominal extension and the dorsal extension may be fixed to the sinker.

  By providing the abdominal extension 4, the center of gravity of the sinker 2 is set on the water bottom side, and the abdomen extension 4 functions as a balancer and is difficult to roll, so that it is easy to reproduce the dirt action. Dirt action is an image of the movement of small fish escaping violently, and is a movement that lures rush left and right (an action that is effective in seasons when fish are actively chasing bait fish) It is said that.) For example, the dirt action involves tying a thread (not shown) to the eye 11, once dandruffing the thread in the water (after loosening), and then lifting the thread and stretching the thread at once, This is a movement utilizing the phenomenon that the forehead of the sinker 2 simulating the head of a fish receives the resistance of water and proceeds in the direction of less resistance to the left or right.

  In particular, in the present embodiment, as shown in FIG. 2, the lateral width of the abdominal extension 4 is set larger than the lateral width of the dorsal extension 5. As a result, the jig head 1 as a whole has a lower center of gravity, and the function as a balancer of the abdominal extension 4 is improved and the sense of stability is further increased, so that it is easier to reproduce the dirt action. In addition, since the jig head 1 is difficult to roll, the jig head 1 and the worm are less likely to be entangled with the thread, and comfortable fishing can be enjoyed.

  The back extension 5 is provided with an annular eye 12. Thereby, a thread | yarn (not shown) can be tied to the eye 12 in back (back side) rather than a conventional product. In the present embodiment, an annular eye 12 is attached to the tip of the back extension 5.

  When the thread is tied to the eye 12 provided on the back side and pulled up more than before, the lure tilts forward with the head at the bottom as a whole, so if you lure the lure while pulling the thread slowly, Receiving the resistance of water, it can reproduce the action like a vibration plug, that is, the action of swimming while vibrating in small increments.

  As described above, the jig head 1 of the present invention makes it easy to reproduce the dirt action by providing the abdominal extension 4, and the vibration of the vibration by providing the back extension 5 provided with the eye 12. A plurality of actions can be reproduced with one jig head 1.

  In the present embodiment, which is a straight hook type jig head 1, a return portion 6 is formed at the end portion of the abdominal extension 4 toward the upper side. In the present embodiment, the return portion 6 is formed by bending the tip of the ventral side extension portion 4 upward toward the root direction of the straight hook 3. When a worm is attached to the straight hook 3, the return portion 6 serves as a keeper and can hold the worm attachment position and angle.

  FIG. 4 is an explanatory view of the state of attachment of the worm to the jig head shown in FIG. 1, in which (a) is attached so that the tip (head) of the soft worm 9 is straight from the tail fin. (B) in the figure shows a state in which the tail fin of the worm 9 is attached so as to hang down. Normally, the worm 9 is attached in the state shown in FIG. 4A. However, in the present embodiment, since the return portion 6 is formed, even if the worm 9 is pushed into the root of the straight hook 3 than usual, the worm 9 is pushed. The mounting position and angle of the worm 9 can be maintained against the restoring force of the worm 9, and when such an installation is performed, the hook is bent (bend) to (b) of FIG. As shown, the tail fin can be attached to hang down. In this way, when the worm 9 is allowed to swim with the tail fin hanging downward, the movement of the worm 9 tail fin swinging left and right can be reproduced.

  According to the above description, the jig head 1 according to the present invention can not only reproduce the motion of the dirt action and vibration, but also form the return portion 6 on the ventral side extension portion 4 so that the worm tail fin can be moved to the left and right. You can also reproduce the movements that you shake. Since multiple actions can be reproduced in this way, the enjoyment of lure fishing increases and the improvement of fishing results can also be expected.

  Furthermore, since the jig head 1 of the present invention has the back side extension part 5 and the ventral side extension part 4, it is possible to express the back part and the abdomen part of the fish by painting and processing them, and a more realistic lure. Can be created. The worm and jig head can be brought close to the form that appears to be integrated, and a lure close to the shape of an actual fish can be made like a swim bait.

  As shown in FIG. 1 and FIG. 3, an eye 13 to which a double hook 20 as an assist hook is detachably attached is provided on the bottom of the sinker 2, and the double hook 20 is fitted to the abdominal extension 4. Fins 7 are provided. In the present embodiment, the eye 13 is provided at the front base portion of the fin 7.

  As shown in FIG. 3, the double hook 20 is formed by connecting two single hooks at the end, and this connecting portion serves as an eye, and a slight gap is formed in the shank portion 21 of each hook. ing. By fitting the gap into the fin 7, the double hook 20 can be fitted into the fin 7. Further, by inserting one needle tip of the double hook 20 into the eye 13, the double hook 20 as an assist hook can be detachably attached to the jig head 1. In the present embodiment, the double hook 20 is used as the assist hook. However, any hook can be used as long as the hook can be fitted into the fin 7.

  Grooves 8 are formed in the fin 7 over a plurality of stages. The groove 8 is formed in a radial shape starting from the eye 13. Thereby, not only the design as a chest fin is expressed, but the mounting angle of the double hook 20 can be changed stepwise by mounting the double hook 20 in each groove portion 8. .

  By attaching the double hook 20 as an assist hook, the hooking probability is naturally improved, but various effects can be exhibited as described below. For example, if the double hook 20 is attached to the fin 7 at the time of casting, the air resistance is reduced, so that the cast flying distance and accuracy can be improved, and yarn entanglement (line trouble) can be avoided. . In addition, since the mounting angle of the double hook 20 can be changed in stages, it is possible to cope with various fish species. For example, when targeting a fish that is inverted like a blue fish or seabass and wants to swallow a bait fish (lure) from the head side, a double hook 20 is set up so that the back and bottom like a flounder or kochi The hooking probability can be increased by laying the double hook 20 on the fish attacking from the direction. On the other hand, the double hook 20 can be easily removed when aiming at a lock fish that does not require an assist hook, when fishing at a place with many roots, or when storing and storing after fishing.

  By the way, in general, a worm is not fixed or fixed to a hook, but is originally attached in a freely replaceable manner. Therefore, when a worm is bitten by a fish or rooted, its attachment position is It is easy to shift. This displacement of the attachment position may be twisted not only in the front-rear and left-right directions, but also in the direction around the hook axis. If the worm deviates from the predetermined position, the way of swimming becomes unnatural, and even if the fish bites, it may not be hooked. Therefore, it is preferable that the worm attached to the jig head does not deviate from a predetermined position even when there is a fish bite or root.

  In the present embodiment, since the return portion 6 is provided, the return portion 6 becomes a keeper, and the ease of displacement of the worm inserted through the straight hook 3 can be reduced. In particular, because the fish bites or roots on the tail of the worm, when the worm is pulled backward (toward the tail), the return part 6 bites into the worm, so the worm comes off. There is almost nothing. In this regard, Patent Document 1 discloses an invention having a worm retaining member on a straight hook shaft. However, since this retaining member needs to be entirely inserted into the body of the worm, It is difficult to insert, and the body of the worm is torn during the insertion process, so that there is a problem that the worm is easily torn off when the fish bites or roots. On the other hand, the present invention employing the above configuration does not cause such a problem.

  FIG. 5 is a side view of an offset hook type jig head 30 according to another embodiment of the present invention, and FIG. 6 is an enlarged view around the offset crank portion of the jig head shown in FIG. In the case shown in FIGS. 5 and 6, the jig head 30 is represented by a silhouette. This is to express that the sinker 31 to which the present invention is applied is not limited to the shape and color imitating the head of a fish.

  The offset hook type jig head 30 includes an offset hook 32 to which a soft resin worm is removably attached and a sinker 31 as in the straight hook type jig head 1 described above. A ventral extension 34 extending rearward is provided on the water bottom side of the sinker 31, and a back extension 35 extending rearward is provided on the water surface side of the sinker 31. An annular eye 33 is provided on the back extension 35. The sinker 31 and the ventral extension 34 or the dorsal extension 35 may be formed by molding integrally with the same material, or may be molded separately and then fixed to each other.

  The offset hook type jig head 30 having such a feature, like the straight hook type jig head 1, makes it easy to reproduce the dirt action by providing the ventral side extension 34, and the back side extension provided with the eye 33. By providing the part 35, it is possible to realize the vibration movement, and a single jig head 30 can reproduce a plurality of actions.

  Further, in the offset hook type jig head 30, the ventral extension 34 is formed toward the offset crank portion 36 of the offset hook 32. As a result, the gap between the sinker 31 and the offset crank portion 34 is reduced, and a pedestal 37 that restricts the movement of the worm is formed below the base of the offset hook 34 as shown in FIG. .

  Then, even when the worm receives a load from the lateral direction (lateral direction when viewed from the advancing direction) and a torsional force is applied to the distal end portion of the worm, the base 37 of the ventral extension 34 restricts the movement of the worm. 7, the movement of the worm tip portion due to torsion is limited, and the gap between the worm tip portion and the offset crank portion 36 is small, so that the worm tip portion as shown in FIG. Can be prevented.

  It should be noted that an upward turn-back portion (not shown) such as the turn-back portion 6 may be formed at the tip of the ventral side extension portion 34. In this case, a worm is formed in the gap between the offset crank portion 36 and The effect that it becomes easy to insert is obtained. Also, in the jig head 30 of the present embodiment, the lateral width of the abdominal extension 34 may be set larger than the lateral width of the back extension 35. In this case, the jig head 30 serves as a pedestal that limits the movement of the worm. Not only is the function improved, but the jig head 30 as a whole has a lower center of gravity and the function as a balancer of the abdominal extension 34 is improved, and the sense of stability is further increased.

  The jig head of the present invention can be used for a worm having a shape other than a straight worm.

  In each of the above embodiments, the eyes 12 and 33 provided on the back-side extensions 5 and 35 are attached separately from the back-side extensions 5 and 35. A through hole may be formed in the part, and the through hole may be used as an eye.

  The present invention can be used as a jig head for lure fishing regardless of fishing grounds.
