Description

The present invention relates to a metal fishing lure called a metal jig.

Conventionally, a metal fishing lure called a metal jig has been used in a fishing method called jigging, in which a lure is moved by jerking a fishing rod. In general, both ends of the metal jig are provided with mounting holes for attaching a fishhook and a fishing line, and the user can control the movement of the metal jig to some extent by attaching a fishing line to the metal jig and swinging the fishing rod. is possible. Piscivorous fish get hooked by misidentifying metal jigs that move in water as live fish.
However, a metal jig with a simple shape behaves simply in water, so there is a limit to imitating the movement of living fish, and there is a problem that it is difficult for fish-eating fish to hook onto the hook. In addition, there is also the problem that it is difficult for women and children to use the jig for a long period of time because it is difficult to use it for a long time because it requires a certain amount of muscle strength and physical strength to use a metal jig that is heavy and made of metal.

In order to make the movement of the metal jig closer to that of a live fish, Japanese Patent Application Laid-Open No. 2016-140356 (hereinafter referred to as “Patent Document 1”) describes a curved water flow receiving portion and a water flow receiving portion that stands upright. A metal lure with an integrally formed tail is disclosed.
The metal jig according to the invention of Patent Document 1 can move left and right imitating the twisting motion of a fish when winding a fishing line attached to the metal jig.

JP 2016-140356 A

However, the metal jig according to the invention of Patent Document 1 cannot realize the above-mentioned movement unless it advances in the winding direction of the fishing line, so the user must frequently jerk the fishing rod or continue winding the fishing line. , the problem of the burden on the user could not be solved.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a metal jig that reproduces the movement of a live fish, attracts the interest of fish-eating fish, and reduces the burden during use.

In order to solve the above problems, the metal jig of the first present invention is a plate-shaped metal jig composed of a substantially streamlined right side surface, a substantially streamlined left side surface, and a thick portion between the right side surface and the left side surface. The metal jig has a twisted portion, and the length of the twisted portion in the longitudinal direction is 40% or more of the total length (refers to the maximum length of the metal jig in the longitudinal direction; the same shall apply hereinafter). do.

The metal jig according to the present invention has a plate-like shape, and has substantially streamlined right and left side portions (hereinafter referred to as "side portions") and has a twisted portion. The water resistance generated in the opposite direction to the fishing direction also extends to the side of the metal jig.
Due to the water resistance received by this side portion, a force is generated in the direction in which the metal jig rotates. If the metal jig rotates sufficiently, this rotation will continue even when the metal jig descends in the water under its own weight after the user finishes jerking the fishing rod once. In addition, the rotation of the metal jig produces a lift force that is higher than the horizontal, and the descending speed of the metal jig is reduced, so it is possible to keep the interval between hiccups longer while continuing to attract the interest of fish-eating fish. Time burden is reduced. In addition, the lift itself reduces the force required to soar again.
In addition, since the metal jig according to the present invention rotates just by continuing to wind the reel, it is possible to continue to attract the interest of the fish-eating fish without the need to hunch the fishing rod.
If you want to lower the metal jig to the bottom of the water, drop it into the water with the longitudinal end of the metal jig facing vertically downward to prevent the generation of lift and drop smoothly.
In addition, since the metal jig according to the present invention is plate-shaped and has a substantially streamlined side surface, the above effects can be achieved even when the fishing line is attached to any end of the side surface in the longitudinal direction. play.
On the other hand, if the ratio of the twisted portion to the entire metal jig is insufficient, the metal jig cannot be rotated sufficiently. Therefore, in order to exhibit the effect of the present invention, the longitudinal length of the twisted portion needs to be 40% or more of the total length, and the twist angle of the twisted portion is preferably 10° or more. .
The effects of the metal jig according to the present invention will be described in more detail below with reference to the drawings.

FIG. 7 is an explanatory diagram showing the direction of the force that the metal jig according to the present invention receives due to water resistance. As shown in FIG. 7, the metal jig 10 according to the present invention has a thick portion 20 and substantially streamlined side portions 30 . The thick portion 20 and the side portion 30 have a twisted portion 40 provided in the center and non-twisted portions 50 provided at both ends, and are integrally formed. The twisted portion 40 has a sufficient longitudinal length of 40% or more of the total length.
When a force is applied in the traveling direction 60 and the metal jig 10 advances in the traveling direction 60, it receives the resistance force 80 of water in the direction opposite to the traveling direction 60.例文帳に追加Since the metal jig 10 has the twisted portion 40, the water resistance force 80 also acts on the side surface portion 30, and a rotational force 90 is generated in a direction that pushes the lower surface of the side surface portion 30 upward. The rotating force 90 causes the metal jig 10 to rotate in the direction of rotation 70 .

8 and 9 are explanatory diagrams showing the lift generated by the rotation of the metal jig in water according to the present invention.
As shown in FIG. 8, the metal jig 10 according to the present invention is rotated in a rotational direction 72 in water. Gravity 100, buoyancy 110, and water resistance 82 are generated in the metal jig 10, and the resultant force of these three forces causes the metal jig 10 to advance in a vertically downward traveling direction 62.例文帳に追加A water flow 140 is generated as the metal jig 10 advances in the traveling direction 62 .
As the metal jig 10 rotates in the direction of rotation 72 in the water flow 140 , the water pressure around the metal jig 10 changes and lift 120 is generated. The direction of lift 120 is perpendicular to the direction of water flow 140 . The metal jig 10 changes its traveling direction due to a resultant force 130 of gravity 100, buoyancy 110, water resistance 82, and lift 120. FIG.
As shown in FIG. 9 , the resultant force 130 causes the metal jig 10 to start moving in the moving direction 64 . At this time, a water resistance force 84 is generated in the direction opposite to the traveling direction 64 . As the metal jig 10 advances in the traveling direction 64, a water flow 142 is generated.
As the metal jig 10 rotates in the direction of rotation 72 in the water flow 142 , the water pressure around the metal jig 10 changes and lift force 122 is generated. The direction of the lift force 122 is perpendicular to the direction of the water flow 142 and above horizontal.

FIG. 10 is an explanatory diagram showing the behavior of a conventional untwisted metal jig in water, showing changes in the position of the metal jig at regular time intervals when the metal jig is pulled up. As shown in FIG. 10, a conventional non-twisted metal jig 150 hovers a fishing rod and is pulled up along a trajectory 170 from a starting point 160 to a fishing point 162. It loses and descends through trajectory 172 under its own weight.
At this time, the metal jig 150, which does not have a twisted portion, does not rotate and sinks down to the bottom 180 while maintaining a substantially uniform posture.
Metal jigs are made of metal and descend quickly in the water, and if the metal jig is left in a state of little movement, the fish won't bite, so the user must frequently shuck the fishing rod.

FIG. 11 is an explanatory diagram showing the behavior of the metal jig in water according to the present invention, and shows the change in the position of the metal jig at the same time intervals as the time intervals in FIG. 10 when the metal jig is pulled up. As shown in FIG. 11, the metal jig 10 according to the present invention sucks the fishing rod and is lifted along the trajectory 170 from the starting point 160 to the fishing point 162. After that, the inertial force in the fishing direction is lost due to water resistance. It descends through trajectory 174 under its own weight.
As described in [0009], the metal jig 10 rotates due to the resistance of water when it is pulled up, and since it has a twisted portion with a sufficient length in the longitudinal direction, even after passing the fishing point 162. Rotation continues.
In addition, as described in [0010], since the metal jig 10 has an upward lifting force rather than a horizontal force, the descending speed becomes gentler than when the metal jig 150 is pulled up.

Next, a metal jig according to a second aspect of the present invention is characterized in that, in the first aspect of the present invention, the twisting angle of the twisting portion is from 10° to 30°.
As the twist angle increases, the force in the direction of rotation generated in the metal jig due to water resistance increases. By setting the twisting angle between 10° and 30°, the rotation becomes appropriate, and a visual effect closer to that of a live fish can be exhibited.

A metal jig according to a third aspect of the present invention is characterized in that, in the first or second aspect of the present invention, the right and left side surfaces are mirror-finished, and the thick portion is not mirror-finished.

By mirror-finishing the side surface, a visual effect similar to that of a fish's scales reflecting light is produced. Also, when the metal jig rotates, the side surfaces diffusely reflect light, so compared to a metal jig that does not have a twisted portion, the mirror-finished visual effect is more pronounced.
In addition, most species of fish have no scales or few scales on their abdomen or back. Therefore, by mirror-finishing only the sides of the metal jig without mirror-finishing the thickness, the visual effect is closer to that of a live fish.

A metal jig according to a fourth aspect of the present invention is the metal jig according to any one of the first to third aspects of the present invention, wherein the portion where the length of the right side portion and the left side portion in the short direction is the maximum is the length of the right side portion and the left side portion in the longitudinal direction. It is characterized by being located 35% to 45% of the total length from one end.

By setting the position where the length of the side surface in the short direction is the maximum as described above, the entire metal jig becomes a fish-like shape, and a visual effect closer to that of a live fish can be exhibited.

A metal jig according to a fifth aspect of the present invention is characterized by being made of stainless steel in any one of the first to fourth aspects of the present invention.

By using stainless steel as the material, it has excellent durability, facilitates mirror finishing, and improves maintainability.

The metal jig according to the present invention can be easily rotated by simply jerking the fishing rod, the descending speed in the water after the jerking is completed becomes gentle, and the interest of fish-eating fish can be continuously attracted even during the descending.
