JP7492095B2 - The rattle structure of the lure and the weight's center of gravity shifting structure - Google Patents

Description

The present invention relates to lures used in fishing and the fishing industry, and more specifically to the structure of the rattles on lures and blades, and the movement of the center of gravity of weights.

Conventional rattles used to attract fish in lure fishing mainly use a mechanism that creates a sound by colliding a rattle ball (or weight) with the inner wall of the lure or the wall inside the rattle tube when the lure swims zigzag in the water or when it is jerked, which is an action that causes the lure to move suddenly (for example, see Patent Document 1 (Figure 2) and Patent Document 2 (paragraphs 0019-0021, Figures 2(a), 2(b), and 3)).

Currently, rattle sounds based on collisions are the norm, and products are available on the market that adjust the sound by changing the material of the rattle ball or the material of the wall that the lure hits (Non-Patent Document 1). Another method for generating a lot of rattle sounds without having to move the lure violently is to place a rattle inside the blade attached to the lure (for example, Patent Document 3).

There are pros and cons about the effectiveness of rattle sounds in attracting fish, but there are also cases where it is better to have a rattle sound and cases where it is better not to have one, and it also depends on noise conditions such as the turbidity of the fishing spot and the undulating currents on the water surface. For this reason, there are also products that allow the rattle to be inserted and removed. (Non-Patent Document 2, Non-Patent Document 3)

In most products, when generating such rattle sounds, the lure (or blade or rattle capsule) needs to be moved violently, and the lure movement is often too violent to warn the target fish. If possible, it is desirable to move the lure quietly, but a means for generating a large number of rattle sounds with a different sound quality from the collision sound even in such a situation is disclosed in Patent Document 4 (see Figures 4, 6, and 8). However, if the direction of the movement path of the rattle ball of this prior art is changed to the longitudinal direction of the lure body to increase the distance, it is possible that the cross section of the movement path will be deformed when the path is bent, impairing the movement of the rattle ball, and this is not suitable for soft lures made of soft body materials such as worms.

A mechanism has also been disclosed in which a rattle ball is substituted for part of a weight, and the weight is moved back and forth to shift the center of gravity, generating a rattle sound at the same time (Patent Document 5). However, this technology also assumes that the weight (or rattle ball) moves in a linear range, and does not assume that the path of movement will be curved, so it is intended for use with hard lures made of hard materials that do not deform. As such, most rattles are intended for use in hard lures, and there are no products intended for use with soft lures such as worms whose body shapes can deform, other than those that emit impact-based rattle sounds as presented in Non-Patent Document 1.

In many cases, the rattle ball and the weight are made of the same material, and in a sense, as in Patent Document 5, the rattle ball can also be said to be a weight, but the main basic technology for moving the center of gravity of weights back and forth has been disclosed (Patent Document 6). The technology in Patent Document 6 is a technology in which a hole is passed through the weight to pass a guide wire (defined as a wire in Patent Document 6) so that the weight (or ball weight) can move linearly back and forth, and it can move back and forth along the guide wire fixed inside the lure body, and further the weight is held in a specified position using the force of a magnet. When the lure is cast, the stress and inertia acting on the weight move the weight to the rear of the lure, which contributes to the effect of stabilizing its posture during flight.

After products using Patent Document 6 flooded the market, many derived technologies were made public, and Patent Document 7 is one of them. Patent Document 7 had unique features (novelty) not seen anywhere else, such as the way the guidewire was used and the shape of the weight, but issues remained in terms of effectiveness (inventive step), and the technology did not progress through the examination request process or to commercialization.

As the technology of shifting the center of gravity by moving the weight of the lure becomes widespread, a technology was disclosed (Patent Document 8) that uses the repulsive (or restoring) force of a spring to return the weight to a designated position, ensuring that the lure is in a horizontal position when it hits the water. However, this technology was not put to practical use. The aim of this technology is to use the repulsive force of a coil spring to return the weight that moves to the rear of the lure when cast to a designated position, ensuring that the lure is in a horizontal position. If the weight at the rear of the lure does not return to its original position, the lure will tread water, which makes the target fish feel uncomfortable. To avoid this, it is considered desirable to maintain a horizontal position in the water.

A technology has been published that has made it possible to put the lure into a horizontal position immediately after it hits the water (Patent Document 9). This technology combines the technologies of Patent Documents 6 and 8 mentioned above, in which a coil spring is provided either at the front or rear of the weight, or at both the front and rear, and the coil spring is compressed or expanded using the stress and inertial force during casting, and the compression or expansion of the coil spring ceases and the weight returns to its designated position when the stress and inertial force acting on the weight after it hits the water subsides. However, if the force of this coil spring is too strong, there is a problem that the weight returns to its designated position unexpectedly quickly during flight, causing the flight posture to become unstable, and so a technology has also been published in which a magnet is used to temporarily slow down or stop the weight when it returns to its designated position (for example, Patent Document 9 (see paragraphs 0010-0016) and Non-Patent Document 4 (see the section "Equipped with the MAGLOCK+R system that combines distance and launch (105S only)")).

The technology in Patent Document 9, which uses a magnet to temporarily slow down or stop the weight, is not particularly important if the strength of the coil spring is set appropriately. Patent Document 10 discloses technology that shows the appropriate values for the strength of the coil spring relative to the weight of the weight used in the technical configuration of Patent Document 9.

As for the technology to automatically return the weight to a specified position immediately after the lure hits the water, the aforementioned Patent Document 9 and Patent Document 10, which is a numerically limited invention for Patent Document 9, are the best technologies currently published. However, the premise of this technology is that a coil spring is provided either at the front, rear, or both sides of the weight, and if a weight other than the weight biased by this coil spring is provided at the front side of the lure (the head side of the lure) or the rear side of the lure (the rear or tail side of the lure), or if the line of movement of the coil spring expanding and contracting is curved rather than linear, it falls outside the range, so depending on the design specifications of the lure, the effective value of the coil spring strength setting may not be valid.

In addition, if the weight of the weight being biased by the biasing force of the coil spring changes while the weight is being returned by the biasing force of the coil spring, or if the weight and the coil spring are arranged differently, the effective value of the strength of the coil spring setting will also not be valid. However, in the case of the technical configuration described in Patent Document 11, both the weight (first weight) directly biased by the coil spring and the parallel weight (second weight, which is a ball weight) are subjects that are pushed equally until the biasing force of the coil spring completes its role, and the movement line of the first weight and the second weight back and forth within the lure is a path that is inclined toward the front of the lure, so that the effective value range of the coil spring setting described above is within a range that does not have a significant effect (for example, Patent Document 11 (the process of returning the first weight and second weight from the state shown in Figure 5 to the state shown in Figure 4)).

However, in the configuration of Patent Document 11, it is necessary to fix the third weight to the belly side (ventral side) of the tail side (rear side of the lure) of the lure. The reason is that without this third weight, when the first weight and the second weight are moved to the tail side, they are lifted to the back side (back side) of the lure, so that when the lure hits the water after casting, the belly side may face the water surface and the back side may face the bottom of the water, and in order to prevent this, the third weight is essential. In addition, the space inside the lure that is occupied by the movement of the first weight and the second weight is large, and it is assumed that the degree of freedom in design is limited and the designer is required to have high design ability.

Currently, soft lures such as worms are not able to move the center of gravity of the weight. The reason this is not possible is that the cross section of the space in which the weight (or rattle ball) moves is damaged by deformation, as described in paragraph 0005 above, but an alternative technology is provided for jointed lures, which are hard lures made up of multiple bodies. (Patent Document 12)

The technology of Patent Document 12 is characterized by a structure in which the weight center of gravity is moved only on the rear body of the lure's front and rear bodies, so designing the lure shape is difficult and the freedom of design tends to be limited due to factors such as adjustment of the weight balance of the front and rear bodies and floating posture in water, restrictions on the swing width and bending angle between the front and rear bodies and adjustment of the bending position, the need to enlarge the internal space of the front body to increase the swing width, and ensuring the strength of the weight center movement structure . If a mechanism for moving the weight center of gravity could be configured to straddle the front and rear bodies, the freedom of design would be improved, but at present, such technology has not been made public.

In addition, because the body of a jointed lure is divided into multiple parts, the front and rear bodies move separately during flight, making the lure's posture unstable and limiting its flight distance, but a prior art solution to this problem is disclosed in Patent Document 13. This technology involves passing a fixed rod between the front and rear bodies during flight, and locking the part that would normally bend with the fixed rod, allowing the lure to fly in the same way as a normal lure with a single body.

However, if the fixed rod described in Patent Document 13 is used in place of a weight, it can be used as a weight that simply moves back and forth, but if a mechanism is incorporated to automatically return it to a specified position using the force of a coil spring, etc., there is a possibility that debris in the water may get tangled or clogged, preventing the lure from moving as intended, leaving issues in terms of practical application. At present, no subsequent technology that can solve this issue has been made public.

In the background art to date, both the movement path of the rattle and the movement path of the weight are linear, and no technology has been identified that guarantees the movement of the weight's center of gravity even if the movement path changes and becomes curved as the lure body deforms. The only technology that seems to be related is Patent Document 14, but it was rejected for other reasons, and as can be seen in paragraph 0013 of Patent Document 14, "preferably, the body does not substantially deform under its own weight," and it is based on the assumption of slight deformation of the body. As a result, it is believed that there is no technology within the scope of publicly known technology that guarantees the movement of the weight's center of gravity and the automatic return of the weight to its designated position when the movement path of the weight changes and becomes curved, whether it is a single body or a body composed of multiple bodies.

Fish eaters (black bass, sea bass, etc.), the target fish of lure fishing, bite the lure because they mistake it for bait (small fish to feed on). It is desirable for the lure to have a rattle sound that attracts fish eaters, an underwater posture that induces the mistake, and a variety of actions.

The problem we are trying to solve is to provide technology that allows the rattle ball to move back and forth without compromising the space it can move in, even inside soft lures such as worms and deformable lures such as jointed lures. If this can produce a variety of rattle sounds without compromising the movement of the rattle ball even when the lure's body deforms, it is believed that this will expand the uses of rattles in worms, soft lures, jointed lures, etc.

Furthermore, if the rattle ball were replaced with a weight and the aforementioned technology were provided, it would be easier to move the center of gravity of the weight, something that has never been done before with worms or soft lures and is rarely done with jointed lures. At the time of filing this application, no technology has been provided that allows the center of gravity of the weight to be moved with worms or soft lures, which are easily deformed. Furthermore, no technology has been provided that allows the center of gravity of the weight to be moved across the bodies of a jointed lure that is made up of multiple bodies, and therefore no technology has been established to return the weight to its designated position.

Even in typical hard lures that are made up of a single body, although it is possible to move the center of gravity of the weight, the technology for returning the weight to its designated position is limited to linear movement, and there is no technology to return the weight to its designated position when the movement of the weight is curved.

The problem that this invention aims to solve is the problem that in conventional technology, when the path along which the rattle ball or weight moves becomes bent, the function is impaired. The objective is to realize a technology for moving the center of gravity of the weight, so that the cross section of the path along which the rattle ball or weight moves is not impaired even if the path along which the rattle ball or weight moves becomes bent, and in particular a mechanism for automatically returning the weight to a specified position immediately after the lure hits the water after being cast, thereby making it possible to use the movement of the center of gravity of the weight in worms, soft lures, and jointed lures as well.

The goal of this project is to provide technology that can produce a variety of rattle sounds that are not limited to the impact sound of the rattle ball that accompanies the process, stabilize the lure's flight posture to increase its flight distance, realize actions by changing the lure's posture immediately after it hits the water, and enable it to return to a horizontal or forward-leaning posture, as well as provide technology that can effectively adjust the lure's swimming posture.

The lure of the present invention is a lure (hard lure, soft lure, rattle capsule, lure blade ) used for fishing, which is provided with a path along which a weight (or rattle ball) built into the lure can move back and forth, and which is configured such that a protection measure for the path along which the weight moves back and forth is provided by a structure having a characteristic bellows-like uneven shape, coil shape, or ring shape for a part or the whole of the path along which the weight moves back and forth, so that the weight can move back and forth even if the lure body is deformed and the path along which the weight moves is bent. This protection measure for the path is an important technology in realizing the present invention, and specifically, a structure is adopted in which a protection measure is provided by providing bellows or coil-like unevenness so as to prevent deformation of the internal cross section through which the weight passes even if the path along which the weight moves is bent.

This structure is common to things that are familiar to us, such as bendable straws, electrical wiring tubes, washing machine drain hoses, and vacuum cleaner hoses. This invention makes it possible to use technology established in other fields in the movement space of the lure's weight, but in order to make this movement space soft and easy to bend or hard and difficult to bend according to the design intent, in the case of a coil spring, it is possible by adjusting the thickness of the wire and the shape of the cross section. For example, if the thickness of the wire coil spring in the direction of expansion and contraction is thinned and flattened outward from the circumference of the coil spring, it will be easier to bend, and vice versa, it will be difficult to bend. As a concrete example, it is easy to understand if you imagine the Slinky described in Non-Patent Document 7.

The rattle sound is generated when the weight (ball weight or rattle ball) moves back and forth over unevenness formed by protective measures in the path of movement, and the sound changes depending on the shape, spacing, and material of these unevenness, making it possible to produce a wide variety of rattle sounds. In particular, when a bellows shape is used, the bellows part is expandable, just like a bendable straw, so it is possible to expand and contract it to change the spacing of the unevenness and adjust the pitch of the rattle sound.

Regarding the technique of returning the weight to a specified position by moving the center of gravity of the weight, when the weight moves back and forth, the weight will tend to stay in place according to the law of inertia when casting the lure, so the coil spring will move toward the rear of the lure while expanding or compressing inside the main body of the lure that is pulled forward. If an expandable spacer is used inside the coil spring at this casting stage, the expandable spacer will be compressed by the stress of the weight. Similarly , if a coil spring is provided behind the weight, the coil spring will be in a compressed state. In the explanation of the means for solving the problem from this paragraph onwards, the explanation will be focused on the case where the coil spring described in claims 2 to 4 is a pull spring.

When the next lure is in flight, the weight will fly with the rear side of the lure at the front with the greatest inertial force, but when the wind resistance that the lure body receives at this time becomes smaller than the force that tries to contract the coil spring, the weight will gradually begin to return to the front side of the lure. If the force of the coil spring is too strong against the weight, the weight will return to the front side of the lure at an early stage of flight, and the weight of the rear side of the lure, which is the front side during flight, will become lighter, causing the flying posture to become unstable due to the influence of the wind and the flight distance to decrease. Conversely, if the force of the coil spring is too weak against the weight, the weight will remain at the rear side of the lure, which is the front side during flight, for a long time, and the lure's lift will not be utilized at the final part of the flight process, and the lure will fall from the rear side of the lure as if it is piercing the water surface. Therefore, the relationship between the strength of the coil spring and the weight of the weight is important, and the method of applying the brakes on the speed of return of the coil spring and the weight is the technology shown in claim 7 of the present invention. This technology is equivalent to regenerative braking in hybrid cars and the like, and although there is no record of its use in lures, it is a proven technology for reel brakes, as shown in Patent Document 15 and Non-Patent Document 6, and utilizes Lenz's Law.

Also, if an expandable spacer is provided inside the coil spring, the spacer will expand before the coil spring contracts and return to its original position. As a result, the distance between the weight at the rear of the lure and the weight that compressed the spacer will increase. This increase in the distance between the weights creates a braking effect by gradually returning the weights rather than all of them returning at once, and distributes the center of gravity back and forth during flight. The effect of distributing the center of gravity back and forth during flight is that it increases stability against crosswinds. If the center of gravity is concentrated on the rear side of the lure, which is the leading edge during flight, and a crosswind hits the lure, the rear end during flight, that is, the front side of the lure, will be easily swept downwind around the center of gravity, and the lure's flight posture will be easily disrupted. Conversely, if the center of gravity is distributed, the entire lure will be evenly exposed to crosswinds, which has the effect of making it less likely to lose its flight posture.

Next, there is a technique for returning the weight to a specified position after it hits the water, and this is done by using the action of a coil spring and spacers, as in paragraphs 0031-0032 above. The moment the lure hits the water, it experiences resistance from the water and suddenly decelerates, so the weight that was returning to the front of the lure moves to the rear end of the lure due to the deceleration, and after the inertial force is lost due to the deceleration in the water, the force of the coil spring and spacer trying to restore the weight to its original state returns the weight to the front of the lure, and the weight is placed in the specified position. This flow of movement is also the same in Patent Document 9, etc., cited in the background art.

In the present invention, not only does the weight return to a specified position, but also an action due to a change in posture is realized on the way of returning the weight to the specified position. The method of realizing this is described in claim 2, "the line of movement within the range where the coil spring expands and contracts can be either straight or curved." For example, if the line of movement within the range where the coil spring expands and contracts draws a curve that makes a U-turn, and the position where the U-turn is made is the back side of the lure, the start of the U-turn is the belly side of the rear side of the lure, and the end of the U-turn is the belly side of the front side of the lure, then when the extended coil spring returns the weight to the specified position, which is the belly side of the front side of the lure, the path of the weight returns to the belly side via the back side. In other words, the center of gravity of the lure moves from the belly side of the lure to the back side and then returns to the belly side, so that when the weight is on the back side, the lure tries to assume a collapsed posture on its back. In the world of lure fishing, this collapsed posture is called "flat-hitting" and is said to be a state where fish eaters are likely to react. For reference, the U-turn movement of a coil spring is easy to understand if you imagine it as being similar to the movement seen in the Slinky mentioned above.

If the part of the mechanism for returning the weight to a specified position in the movement of the weight's center of gravity explained in paragraphs 0031 to 0035 above, "the line of movement within the range in which the coil spring expands and contracts can be either straight or curved," is placed in a space where measures have been taken to protect the movement path of the weight, as explained in paragraph 0028, then a mechanism for moving the center of gravity across the bodies of a lure consisting of multiple bodies, such as a jointed lure, can be realized. The same is true for soft lures, and in the case of center of gravity movement using the repulsion of magnets, this can be achieved simply by placing the lure in a space where measures have been taken to protect the movement path.

The lure, lure rattle structure, and weight center of gravity shifting structure of the present invention stabilize the flight posture during casting, and the weight that has moved to the rear of the lure is returned to the front of the lure by a coil spring when the lure hits the water, achieving the correct underwater posture. It is also possible to perform actions such as flapping in the process of achieving the underwater posture, and this technology is the first to make it possible to shift the center of gravity even in jointed lures and soft lures that are made up of multiple bodies. The same is true for center of gravity shifting using magnetic repulsion.

When used as a rattle, it is possible to produce a variety of rattle sounds. In particular, the bellows-shaped hose is stretchable just like the bending part of a straw, so when used by inserting it into a worm at the fishing spot, you can set the rattle sound of your choice by stretching the bellows part.

Furthermore, compared to the conventional method of providing a coil spring in front of or behind the weight, the method of the present invention of placing the weight inside the coil spring, or placing a coil spring inside the weight , makes it possible to increase the movable area in which the weight moves back and forth, thereby improving design options and freedom in terms of increasing the casting distance and changing the underwater posture from horizontal to forward tilting.

The present invention will now be described in detail with reference to the illustrated embodiment. Note that modifications to this embodiment may be made within the technical scope of the present invention.

The following describes an embodiment of claim 1. Note that the hooks (fish hooks) not necessary for the description of the present invention are omitted from the drawings of the embodiment from this paragraph onwards.

Figure 2 is a perspective view including a cross-sectional view showing that space is secured for the movement path of the ball weight (rattle ball) 4 in the figure, and examples of the means for securing the movement space are shown in Figures 2(a), (b), and (c). Figure 2(a) shows that space is secured for movement inside the bellows hose 1, and as a means for securing the space, bellows peaks 5 and bellows valleys 6 are provided alternately, and are configured to prevent crushing from the outside and inside in the circumferential direction even if the bellows hose 1 is bent. Similarly, in Figure 2(b), the unevenness of the ring 7 of the ring hose 2 plays a role in securing the movement space. Similarly, in Figure 2(c), a coil (coil spring) 8 plays a role in securing the movement space.

In Fig. 2, as in Fig. 2(a), the bellows hose 1 secures the space for the movement path of the ball weight (rattle ball) 4, but in Fig. 2(b) and (c), the movement path is secured by the ring 7 and coil (coil spring) 8, and the space is secured by the ring hose 2 and coil hose 3, which encase them. This is merely an example when used in the form of a rattle capsule (described below, Fig. 4(b) 12). If the role of securing space is to be given to the lure body itself, a space equivalent to the bellows hose 1, ring hose 2, and coil hose 3 can be provided inside the lure body, and then a ring 7 and coil (coil spring) 8 can be provided on top of that to similarly realize a movement space that will not collapse.

Figure 3 is a cross-sectional view showing a means for making the rattle ball 4 in the figure generate or not generate a rattle sound. Figure 3(a) shows a ring hose 2, but since the rings 7 are configured to be convex on the inside and outside of the hose, when the rattle ball 4 moves inside the hose it moves over the convex parts, generating a rattle sound. In this case, if the spacing between the rings 7 is narrow, a fast-paced rattle sound is generated, and if the spacing is wide, a slow-paced rattle sound is generated.

Figure 3(b) also shows a ring hose 2, but it is configured so that the ring 7 does not protrude inside the hose, and the space in which the rattle ball 4 moves is flat. In such a case, even if the rattle ball 4 moves, no rattle noise is generated while it is moving, and collision-type rattle noise is generated only when it reaches both ends of the hose. If you want to suppress the rattle noise even when it reaches both ends of the hose, you can suppress the rattle noise by closing both ends with a soft material. The need to suppress this rattle noise is often seen when you want the rattle ball 4 to focus on moving the center of gravity as a weight.

Figure 3 (c) is an embodiment drawing showing an example of the coil spring described in paragraph number 0029 above, which has a flattened cross section to make it easier to bend. In the enlarged portion, it can be seen that the coil (flattened coil spring) 10 is arranged flat in the circumferential direction of the coil hose 3. With this configuration, the coil hose 3 becomes soft and easy to bend, enabling movement that corresponds to the softness required of a lure. Furthermore, when flattened in the circumferential direction, the coil hose 3 becomes stronger than a normal coil hose even when subjected to water pressure.

Figure 4 shows an example of a lure (soft lure, worm) 11 with a rattle capsule 12. From the cross-sectional view of the rattle capsule (cross-sectional view) 13 in Figure 4(b), it can be seen that a ball weight (rattle ball) 4 is provided inside the capsule, making it possible to generate a rattle sound.

Figure 5 shows an example of using a rattle capsule 12 in a lure (metal jig) 14. As shown in the cross-sectional view of Figure 5(b), a rattle capsule 12 can be provided inside the lure (metal jig) 14, but recently, as shown in the aforementioned non-patent document 2, there are also products with rattle slits 16 into which the rattle capsule 12 can be attached, and similar usage is also possible.

Figure 6 shows an embodiment in which a rattle capsule 12 is used in a lure blade 17. As shown in the cross-sectional view of Figure 6(b), the rattle capsule 12 can be provided inside the lure blade 17 , so it is not used alone but is used by attaching it externally to a lure (metal jig) 14 or various lures as shown in Figure 7. Unlike normal lure blades, it is effective when used when you want to attract fish with a variety of rattle sounds.

Fig. 7(a) shows the posture of the lure (metal jig) 14 when it is jerked upwards, and the lure (metal jig) 14 is pulled upwards as it is raised to the water surface , and the lure blade 17 is also pulled upwards, so the internal ball weight (rattle ball) 4 moves to the opposite side of the lure blade 17 by inertia, generating a rattle sound. Fig. 7(b) shows the lure (metal jig) 14 sinking, which is called a fall, but since the lure blade 17 generally has a lighter specific gravity than the lure (metal jig) 14, the lure blade 17 sinks as it is pulled by the lure (metal jig) 14. In this case, the speed of the lure falling due to gravity is greater than the speed of the lure sinking, so the ball weight (rattle ball) 4 inside the lure blade 17 falls first and moves to the side of the lure (metal jig) 14 to which it is connected, generating a rattle sound.

The following describes an embodiment of claim 2.

8A and 8B are perspective views including a cross-sectional view showing the state in which the ball weight (rattle ball) 4 can move back and forth inside the lure (hard lure) 22, and in Fig. 8A, it can be seen that the ball weight (rattle ball) 4 is housed in the front space inside the lure (hard lure) 22, and the coil (coil spring) 8 is also housed in a contracted state. This state is the normal state in which the lure is swimming, and represents the state in which the ball weight (rattle ball) 4 is placed in a specified position. Note that the coil (coil spring) 8 in Fig. 8 is assumed to be a tension spring.

Figure 8 (b) shows the state of Figure 8 (a) with the ball weight (rattle ball) 4, coil (coil spring) 8, spring base (spring fixing device) 23, and spring cap (cap pillar weight) 24 removed. In this, the spring base (spring fixing device) 23 has the role of fixing the coil (coil spring) 8 to the main body of the lure (hard lure) 22, and the spring cap (cap pillar weight) 24 is provided on the tail hook eye 27 side in the direction in which the coil (coil spring) 8 extends so that the ball weight (rattle ball) 4 does not jump out of the coil (coil spring) 8. As a result, when the line eye 25 is lifted up before casting the lure, the ball weight (rattle ball) 4 enters the inside of the coil (coil spring) 8 through the hole opened in the spring base (spring fixing device) 23 and stops at the spring cap (cap pillar weight) 24.

When the lure is cast and stress (inertial force) is applied to the rattle ball 4, the coil (coil spring) 8 is fully stretched by the strong stress of the rattle ball 4 as shown in Figure 8(c), but as the lure flies, it is subjected to wind resistance and the inertial force is gradually lost, and the position of the rattle ball 4 and the state of the coil (coil spring) 8 return to the state shown in Figure 8(b). When the lure hits the water and encounters water resistance, it returns to the state shown in Figure 8(c), and when the lure comes to a complete stop in the water, the stress on the coil (coil spring) 8 disappears and the coil (coil spring) 8 contracts, pushing the rattle ball 4 back to its original position and returning to the state shown in Figure 8(b).

The process from paragraphs 0053 to 0055 above explains the basic movement that corresponds to claim 2 of the present invention, but as shown in Figure 9 (b), depending on the type of weight, even a column-shaped weight can be used.

Figure 10 shows an embodiment in which the weight's movement path is curved. In Figure 10, the characteristic of the movement of the coil (coil spring) 8, which is a feature of claim 2 of the present invention, is utilized, making it possible to make maximum use of the internal space of the lure by including a curve in the movement path of the weight.

Figure 10(a) shows the coil (coil spring) 8 in an extended state when the lure is cast, and the rattle ball 4 makes a large detour around the top of the lure from its designated position, passing through the coil (coil spring) 8 to the rear end of the lure. After landing on the water, it tries to return to its designated position as in paragraph 0054 above, but the rattle ball 4 makes a large detour around the back of the lure, so the center of gravity of the lure is placed on the back of the lure at this detoured position. As a result, the back of the lure becomes heavy and it falls to the side, so it loses balance by falling to its side or on its back as shown in Figure 10(b). This state of losing balance is called "flat-hitting" and is a posture that fish eaters respond well to.

After Figure 10(b), the rattle ball 4 returns to its designated position as shown in Figure 10(c), but by adjusting the buoyancy balance of the body shape of the lure (hard lure) 22, it is possible to stop it in the "fluttering" position and make it look like a weakened small fish. Depending on the field in which the lure is used (sea, lakes, rivers, etc.), the effects vary, so it is desirable to use different designs depending on the location and purpose of the lure. In this way, the present invention also offers diversity in terms of design.

Paragraphs 0053 to 0059 show an example of a coil (coil spring) 8 that is assumed to be a tension spring, but Figure 11 shows an example in which a compression spring is used. Figure 11(a) shows the normal state in which the lure is swimming, with the rattle ball 4 placed in a specified position.

Figure 11(b) shows the state of Figure 11(a) with the ball weight (rattle ball) 4, coil (coil spring) 8, spring rear base (spring fixing device) 51, and spring front cup (ball weight receiver) 52 removed. Among these, the spring rear base (spring fixing device) 51 has the role of fixing the coil (coil spring) 8, which is a compression spring, to the lure body. The spring front cup (ball weight receiver) 52 has the role of receiving the ball weight (rattle ball) 4 at the front side of the lure, and when it receives the weight or stress of the ball weight (rattle ball) 4, it has the role of compressing the coil (coil spring) 8 as shown in Figure 11(c). Note that Figure 11(c) shows the state in which the ball weight (rattle ball) 4 is contained in the pocket part of the spring front cup (ball weight receiver) 52, and is also contained inside the coil (coil spring) 8.

An embodiment according to claim 3 will be described below. Note that the coil (coil spring) 8 used in this embodiment is an example that assumes a tension spring. In addition, embodiments in which claims 6 and 7 are adopted in addition to claim 3 will also be described.

Figure 12 is a perspective view including a cross-sectional view showing the state in which the cylindrical weight (cylindrical weight) 29 can move back and forth inside the lure (hard lure) 22, and in Figure 12(a) you can see how part of the cylindrical weight (cylindrical weight) 29 fits inside the lure (hard lure) 22, hiding it inside the contracted coil (coil spring) 8. This is the normal state when the lure is swimming, and represents the state in which the cylindrical weight (cylindrical weight) 29 is placed in a specified position.

Fig. 12(b) shows the state where a set of parts related to the movement of the center of gravity of the weight, including the cylindrical weight (cylindrical weight) 29, has been extracted from Fig. 12(a). Since a part of the cylindrical weight (cylindrical weight) 29 that fits into the coil (coil spring) 8 cannot be seen in Fig. 12(a), Fig. 12(b) shows the coil (coil spring) 8 divided in half so that it can be seen that it fits inside. In addition, the cylindrical weight (cylindrical weight) 29 is stopped at a position where the coil (coil spring) 8 is contracted and the guide wire (hard wire) 30 is bent at a right angle on the front side of the lure, and is fixed between the contraction force of the coil (coil spring) 8 and the guide wire (hard wire) 30.

When the lure is cast and stress (inertial force) is applied to the cylindrical weight (cylindrical weight) 29, the coil (coil spring) 8 is subjected to the strong stress of the cylindrical weight (cylindrical weight) 29 and fully stretches as shown in Figure 12 (c), but as the lure flies, it is subjected to wind resistance and the inertial force is gradually lost, and the position of the cylindrical weight (cylindrical weight) 29 and the state of the coil (coil spring) 8 return to the side shown in Figure 12 (b). When the lure hits the water and encounters water resistance, it returns to the state shown in Figure 12 (c), and when the lure comes to a complete stop in the water, the stress on the coil (coil spring) 8 disappears and the coil (coil spring) 8 contracts, pushing the cylindrical weight (cylindrical weight) 29 back to its original designated position, returning it to the state shown in Figure 12 (b).

Figure 12(d) shows the cylinder weight (cylindrical weight) 29 by itself. It has a groove for fixing it to the stretching side of the coil (coil spring) 8. The cylinder weight (cylindrical weight) 29 has two roles: a cap that prevents the weight from slipping out of the inside of the coil spring, and a weight that moves back and forth inside the coil spring.

The process from paragraphs 0063 to 0065 above explains the basic movement of the weight that corresponds to claim 3 of the present invention.

In Figure 13, a wheel weight (ball weight with wheel axle) 34 is also used compared to the embodiment in Figure 12. Therefore, a guide wire 2 (hard wire) 32 is provided so that the wheel weight (ball weight with wheel axle) 34 can move back and forth properly.

Figure 13 (a) shows the state during casting, and it can be seen that the coil (coil spring) 8 expands and the spring cap (cap pillar weight) 24 and wheel weight (ball weight with wheel axle) 34 move toward the rear of the lure. The wheel weight (ball weight with wheel axle) 34 is guided by the guide wire 2 (hard wire) 32 and passes through the inside of the coil (coil spring) 8, pushing the spring cap (cap pillar weight) 24. When the lure hits the water, the coil (coil spring) 8 contracts as shown in Figure 13 (b), returning it to the specified position and state.

In Figures 13(c) and 13(d), the coil (coil spring) 8 and other parts are not shown to make it easier to see the positional relationship between each weight and guide wire.

Figure 14 shows the embodiment of Figure 13 in which multiple guide wires are provided. Figure 14(d) is the easiest to confirm, but in the embodiment of Figure 14, the guide wires are a front guide wire (hard wire) 35 and a rear guide wire (hard wire) 36, and in the movement line portion where they overlap with the coil (coil spring) 8, the rear guide wire (hard wire) 36 is used, and in the non-overlapping portion, the front guide wire (hard wire) 35 guides the forward and backward movement of the wheel weight (ball weight with wheel axle) 34.

Fig. 15 shows an embodiment in which claim 6 is applied to claim 3 of the present invention. The differences between Fig. 12, Fig. 13, and Fig. 14 mentioned above are that a soft guide wire (soft wire) 38 is used as the guide wire, that a round ball-shaped through-hole weight 37 is used as the ball weight, and that the spacer according to claim 6 is provided as spacer 28 in Fig. 15(b), (c), and (d), and the expandable spacer is provided as spacer 29 in Fig. 15(e) and (f), respectively. If the weights are distributed using spacers, the effect of making it easier to stabilize even when subjected to crosswinds is obtained, as explained in paragraph number 0033. The type of spring used in spacer 2 (expandable) is a compression spring.

FIG. 16 shows an embodiment in which claims 6 and 7 are applied to claim 3 of the present invention. The major difference from the configuration based on FIG. 12 above is that an aluminum pipe 40, a magnetic weight 41, and a spacer 2 (retractable) 39 are provided. The spacer 2 (retractable) 39 was mentioned in paragraph number 0072, so a detailed explanation will be omitted. As shown in FIG. 16(b), the aluminum pipe 40 and the magnetic weight 41 are placed at separate positions when the lure is in flight, and as shown in FIG. 16(c) and (d), when the magnetic weight 41 enters the inside of the aluminum pipe 40, the aluminum pipe 40 is influenced by the magnet and generates an eddy current according to Lenz's law. This applies a brake, and the time it takes for the weight to return to the specified position is slightly delayed. The delay also leads to a slow and stable movement, which contributes to the stability of the lure's posture during flight.

An embodiment according to claim 4 will be described below. Note that this embodiment is an embodiment in which a compression coil spring 2 (for the inner spring) 54 and a tension coil spring (for the inner spring) 60 are used. In addition, the embodiment includes embodiments in which claims 6 and 7 are adopted in addition to claim 4.

Figure 17 is a perspective view including a cross-sectional view showing the state in which the cylindrical weight 3 (internal spring type cylindrical weight) 53 can move back and forth inside the lure (hard lure) 22, while Figure 17(b) shows that the cylindrical weight 3 (internal spring type cylindrical weight) 53 is placed inside the lure (hard lure) 22, with an internal spring weight connector 55 inserted inside it, and an extended compression coil spring 2 (for the internal spring) 54 built in inside that. This is the normal state when the lure is swimming, and represents the state in which the cylindrical weight 3 (internal spring type cylindrical weight) 53 is placed in a specified position.

Figure 17(b) shows the state in which the set of parts related to the movement of the center of gravity of the weight, including the cylinder weight 3 (internal spring type cylindrical weight) 53, has been extracted from Figure 17(a). Since the state of the compression coil spring 2 (for the inner spring) 54 that fits inside the cylinder weight 3 (internal spring type cylindrical weight) 53 cannot be seen in Figure 17(a), Figure 17(b) shows the compression coil spring 2 (for the inner spring) 54 and the inner spring weight connector 55 cut in half so that it can be seen how they fit inside.

When the lure is cast and stress (inertial force) is applied to the cylindrical weight 3 (internal spring type cylindrical weight) 53, the compression coil spring 2 (for internal spring) 54 is compressed by the strong stress of the cylindrical weight 3 (internal spring type cylindrical weight) 53 as shown in Figures 17(c) and 17(d). However, as the lure flies, the inertial force is gradually lost due to wind resistance, and the position of the cylindrical weight 3 (internal spring type cylindrical weight) 53 and the state of the compression coil spring 2 (for internal spring) 54 return to the side of Figure 17(b). When the lure hits the water and encounters water resistance, it returns to the state of Figure 17(c). When the lure comes to a complete stop in the water, the stress applied to the cylindrical weight 3 (internal spring type cylindrical weight) 53 disappears, and the compression coil spring 2 (for internal spring) 54 expands and pushes the cylindrical weight 3 (internal spring type cylindrical weight) 53 back to its original specified position, returning to the state of Figure 17(b).

In Figure 17(d), it can be seen that the compression coil spring 2 (for the inner spring) 54, compressed under stress, is contained inside the cylinder weight 3 (inner spring type cylindrical weight) 53, and this state is a feature of the present invention (the effect of increasing the movable area in front and behind the weight) that has not been realized in conventional technology. Note that Figure 17(e) shows the cylinder weight 3 (inner spring type cylindrical weight) 53, compression coil spring 2 (for the inner spring) 54, and inner spring weight connector 55 in a separated state to make it easier to see the configuration and shape.

When the configuration shown in FIG. 17 is used, it differs from the technical configuration assumed in the aforementioned Patent Document 10, but the appropriate setting value for the relationship between the strength of the coil spring and the weight of the weight ball presented in Patent Document 10 can be used as a reference.

The only difference between Figure 18 and Figure 17 is the use of a compression coil spring 3 (for floating inner spring) 61. In comparison with Figure 17(b), Figure 18(b) shows that the compression coil spring 3 (for floating inner spring) 61 does not reach the position of the stopper (shock absorbing rubber) 31. In this way, the compression coil spring 3 (for floating inner spring) 61 is not fixed inside the lure body and is left floating. Figure 18(c) shows the state where it has escaped from the inside of the weight. Even with this configuration, if the cylinder weight 3 (inner spring type cylindrical weight) 53 is stressed and the compression coil spring 3 (for floating inner spring) 61 is compressed, it will be in the state shown in Figure 18(d). This configuration is effective when you want to intentionally set the weight not to return completely after it hits the water.

While Figures 17 and 18 are examples using a compression coil spring, Figure 19 is an example using a tension coil spring, and is an example in which claims 6 and 7 are adopted. Figure 19 is a perspective view including a cross-sectional view showing a state in which the cylindrical weight 3 (internal spring type cylindrical weight) 53, the spacer 3 (for internal spring) 58, and the magnet weight 2 (for internal spring) 59 are movable back and forth inside the lure (hard lure) 22, and Figure 19(b) shows a set of parts related to the movement of the center of gravity of the weight, including the cylindrical weight 3 (internal spring type cylindrical weight) 53, extracted from Figure 19(a).

In Fig. 19(b), it can be seen that the inner spring weight connector 55 is inserted inside the cylinder weight 3 (inner spring type cylindrical weight) 53, the spacer 3 (for inner spring) 58, and the magnet weight 2 (for inner spring) 59, and further inside that, the extended tension coil spring (for inner spring) 60 is built in. This state is the normal state when the lure is swimming, and the cylinder weight 3 (inner spring type cylindrical weight) 53, the spacer 3 (for inner spring) 58, and the magnet weight 2 (for inner spring) 59 are placed in the predetermined positions, and the aluminum pipe 40 is placed on the outer periphery of this predetermined position.

When the lure is cast and stress (inertial force) is applied to the cylindrical weight 3 (internal spring type cylindrical weight) 53, the spacer 3 (for internal spring) 58, and the magnet weight 2 (for internal spring) 59, the tension coil spring (for internal spring) 60 is subjected to strong stress and extends as shown in Figures 19(c) and 19(d). However, as the lure flies, the inertial force is gradually lost due to wind resistance, and the position of the cylindrical weight 3 (internal spring type cylindrical weight) 53 etc. and the state of the tension coil spring (for internal spring) 60 return to the side of Figure 19(b). When the lure hits the water and encounters water resistance, it returns to the state of Figure 19(c). When the lure comes to a complete stop in the water, the stress applied to the cylindrical weight 3 (internal spring type cylindrical weight) 53 etc. disappears, and the tension coil spring (for internal spring) 60 contracts and pushes the cylindrical weight 3 (internal spring type cylindrical weight) 53 etc. back to their original designated positions, returning them to the state of Figure 19(b). When returning to this predetermined position, Lenz's law comes into effect between the magnet weight 2 (for the inner spring) 59 and the aluminum pipe 40, and the magnet returns slowly with the brake applied.

The embodiments according to claims 1 and 2 will be described below.

Fig. 20(a) shows an embodiment of a lure (hard lure) 22 composed of two bodies, a lure front body 22a and a lure rear body 22b. The weight's center of gravity moving part is shown in Fig. 20(b), (c), and (d), but it is basically the same as the means of claim 2. By storing the weight's center of gravity moving part in the body connecting hose 43 in Fig. 20(b) where "space for the moving path is secured", it is possible for the weight to move across the two divided lure front body 22a and lure rear body 22b. The lure front body 22a and the lure rear body 22b are connected by a joint metal fitting 42, and when this part moves, the lure front body 22a and the lure rear body 22b swing left and right when viewed from above, but since "space for the moving path is secured", the weight can move back and forth without any problems.

The only difference between the embodiments in Figures 21 and 20 is that the weight movement means has been changed from claim 2 to claim 3. As with Figure 20, the weight can be moved back and forth without any problems in the area where "space is secured for the movement path."

The only difference between the embodiments in Figures 22 and 21 is that the weight movement means is replaced with claim 4. In the part where "space for the movement path is secured," the weight can move back and forth without any problems, just like in Figures 20 and 21.

Figure 23 is a plan view of the configuration of Figure 21 from above, but the only difference is that the length of the guide wire (soft wire) 38 is shortened. As a result, it can be confirmed that the position of the cylindrical weight (cylindrical weight) 29 in Figure 22 (c), which corresponds to the state of the weight during the flight of the lure, is located in the middle of the two bodies, the lure front body 22a and the lure rear body 22b. This state corresponds to a state that works similarly to the "bending part is locked with a fixed rod" in Patent Document 13 mentioned in paragraph number 0017 above, and makes it possible to contribute to the stability of the lure's posture during flight.

Fig. 24 is a plan view of the configuration of Fig. 22 seen from above, but the only difference is that the length of the guide wire (soft wire) 38 is shortened as in Fig. 23. As a result, the position of the cylindrical weight 3 (internal spring type cylindrical weight) 53 in Fig. 24(c), which corresponds to the state of the weight during the flight of the lure, is located in the middle of the two bodies, the lure front body 22a and the lure rear body 22b, and corresponds to the state of being locked by the fixed punch as in the example of Fig. 23.

An embodiment according to claim 5 will be described below by comparing it with an embodiment in which claim 2 or claim 3 is adopted in addition to claim 1 .

Figure 25 (a) shows an embodiment of the lure (hard lure) 22, which is composed of two bodies, the lure front body 22a and the lure rear body 22b. The weight's center of gravity moving part is shown in Figures 25 (b), (c), and (d), and the only difference between this weight's center of gravity moving part and the procedure shown in claims 2 and 3 is that the means for returning the weight to a specified position is that the compression coil spring 48 is placed on the lure rear side of the cylindrical weight 2 (cylindrical weight) 47. During flight after casting the lure, the weight is expanded and compressed from the inside of the coil (coil spring) 8 in the above-mentioned claims 2 and 3, but in the means shown in Figure 25, the compression coil spring 48 is compressed from the lure front side, which is a difference in the way the coil spring is used.

An embodiment according to claim 8 will be described below.

Figure 26 shows an embodiment of a lure (hard lure) 22 consisting of two bodies, a lure front body 22a and a lure rear body 22b. The moving part of the weight's center of gravity is shown in Figures 26(b), (c), and (d). Unlike the above-mentioned configuration using a coil spring, this moving part of the weight's center of gravity uses a method of returning the weight to a specified position by using the repulsive force between magnets instead of a coil spring. Figure 26(b) shows the state in which the weight is in a specified position when the lure is swimming. When the lure is cast and stress is applied to the weight, the weight moves to the rear side of the lure as shown in Figure 26(c). At this time, the repulsive magnet 1 (lure rear side) 62 and the repulsive magnet 2 (weight rear side) 63 approach each other, but since the faces of the magnets with the same polarity face each other, they repel each other, and stop at a distance where the stress on the weight and the repulsive force between the magnets are balanced. When the stress on the weight is lost, the repulsive force between the magnets prevails, and the cylinder weight 4 (magnet repulsion weight) 64, the repulsion magnet 2 (rear weight side) 63, and the ball weight (rattle ball) 4 are pushed back to their designated positions.

1 shows an embodiment that is configured with a body that is assumed to be softly deformed by a lure (soft lure) 11. As shown in Fig. 1(a) and Fig. 1(b), the weight's center of gravity moving portion is provided inside the lure (soft lure) 11 , and a line eye 25 for tying a fishing line is provided outside the lure (soft lure) 11 .

Figures 1(e) and 1(f) correspond to the embodiment of claim 5 , and Figure 1(e) shows the state where the weight is set in a predetermined position with the compression coil spring 48 pushing the round ball type through-hole weight 37 to the front side of the lure. In contrast, Figure 1(f) shows the position of the weight when the lure is cast, and shows the state where the compression coil spring 48 is compressed by the inertial force of the round ball type through-hole weight 37 and the center of gravity of the weight moves to the rear side of the lure. When the lure hits the water, the round ball type through-hole weight 37 is pushed by the compression coil spring 48 and returns to the predetermined position, returning to the state of Figure 1(e).

Fig. 1(c) and Fig. 1(d) are examples according to claims 1 and 2 , but comparing Fig. 1(d) and Fig. 1(f), Fig. 1(d) allows the ball weight (rattle ball) 4 to move using the space it can move to the maximum, whereas Fig. 1(f) requires a space for the compressed coil spring 48 to exist in a compressed state at the destination of the round ball-shaped through-hole weight 37. For this reason, it can be said that the effect of the weight's forward and backward movement can be maximized by arranging the weight so that it is built into the coil (coil spring) 8, rather than providing the compressed coil spring 48 behind the weight.

The lure of the present invention is suitable for fishing in the ocean, lakes, rivers, and other areas.

Claims (8)

This lure is used for fishing, and has a path along which a weight built into the lure can move back and forth, and a path protection measure is provided for part or all of the path along which the weight moves back and forth, using a structure characterized by a bellows-like uneven shape, a coil shape, or a ring shape, so that even if the lure is deformed and the path along which the weight moves inside is bent, the path protection measure ensures a space for the weight to move back and forth, and the lure can also have unevenness raised on the surface where the weight meets the path to generate a rattle sound, or have no uneven surface to prevent the generation of a rattle sound . A lure used for fishing, in which a coil spring and a weight are placed inside the lure body, and the line of movement within the range in which the coil spring expands and contracts can be either straight or curved, one end of the coil spring is fixed inside the lure body, and the other end of the coil spring is either closed or closed by a cap or cup that receives the weight, or by the weight itself, and some or all of the weight is arranged so that it can move back and forth inside the coil spring, or move from the inside of the coil spring to the front hollow part inside the lure body that is outside the coil spring and is not affected by the stress of the coil spring , or some or all of the weight is arranged so that it can move back and forth on the front side of the lure from one end of the closed coil spring, and when the weight or stress of the weight is applied to the closed end of the coil spring, the coil spring expands or compresses, causing the weight to move toward the rear end of the lure, and when the weight or stress is reduced or released, the restoring force of the coil spring allows the weight to return to its original designated position. In the lure of claim 2, a guide wire made of one or more hard or soft wires is provided inside the lure, a portion of the guide wire is extended inside the coil spring, and a through hole for the guide wire is provided in the weight so that some or all of the weight can move back and forth inside the coil spring along the guide wire , or can move between the front hollow part inside the lure body which is the outside of the coil spring , or a wheel-type weight having an axle is provided so that the weight can roll between the inside of the coil spring and the front hollow part inside the lure body which is the outside of the coil spring along the guide wire. A fishing lure having one or more weights that move back and forth within the internal space of the lure, and one or more guide wires that guide the back and forth movement of the weights, and a coil spring that can return the weights to a predetermined position when the weights move under stress, a space is provided inside the weights to accommodate a contracted or compressed coil spring, one end of the coil spring is directly or indirectly fixed to the weights or is provided in a state in which it can move freely so as to receive the stress of the weights, and the other end of the coil spring, in the case of a pull spring, is connected to the weights in the internal hollow portion of the lure. When the weight is subjected to stress, in the case of a pull spring, the weight moves to the rear side of the lure in the hollow portion of the lure while pulling the pull spring, and in the case of a push spring, the weight moves to the rear side of the lure in the hollow portion of the lure so as to compress the push spring. When a pull spring is used, the weight is arranged to fit within the space inside the weight when contracted, and when a push spring is used, the weight is arranged to fit within the space inside the weight when compressed under stress. 2. The lure according to claim 1, wherein a guidewire made of a soft wire is provided in a movement path where a movement path protection measure has been taken for the weight built into the lure, one end of the guidewire is fixed to the front side inside the lure and the other end of the guidewire is provided at the rear side inside the lure either fixed or free to move freely, the weight that moves back and forth within the movement path has a through hole through which the guidewire passes , and a coil spring is provided between the weight and the one end of the guidewire on the rear side of the lure, and the coil spring is contracted when subjected to the weight or stress of the weight , and when released from the weight or stress, the coil spring expands to push the weight back to the front side of the lure, causing the weight to return to its original position, and one end of the guidewire on the rear side of the lure is provided with a stopper or is fixed to prevent the coil spring or weight from slipping out. A lure comprising a plurality of weights as described in claim 2, 3, 4 or 5 , and a spacer capable of expanding and contracting by a spacer or a coil spring is provided between the weights. A lure in which the whole or part of the movement path of the weight according to claim 2, 3, 4, 5 or 6 is surrounded by a non-magnetic conductive material , and a part or all of the weight that moves back and forth is made of a magnetic material. The lure according to claim 1, wherein one or more weights are provided on a path of movement of the weight built into the lure , and a magnet is attached to the weight on the rear side of the lure, and a magnet is also provided at the end of the path of movement of the weight on the rear side of the lure so as to repel the magnet attached to the weight, so that when the weight is subjected to stress, the weight moves to the rear side of the lure while being repelled by the magnet, and when the weight is released from the stress, the repulsive force of the magnet allows the weight to return to a predetermined position.
