Abstract
Description
[Technical Field]
[0001] The present invention relates to a lure and an artificial bait that imitates a fish or the like used in fishing. [Background technology]
[0002] The lure according to the prior art is composed of a body that resembles a fish or the like and a fishing hook attached to the body, and is propelled through the water by pulling the fishing line connected to the tip of the body. At this time, it is desirable for the artificial bait or lure to behave like a live fish in order to attract fish and encourage their predatory behavior.
[0003] Therefore, the lure's body may be divided into multiple sections, and each section may be connected with a flexible connector to allow movement. Alternatively, the lure may be connected to the body using a flexible, elastic material like rubber, without using a connector, allowing each section to bend. In either case, the aim is to use the water flow generated around the lure to change the shape of the body, attracting the attention of fish and stimulating their feeding behavior. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-187248 [Patent Document 2] Japanese Patent Application Laid-Open No. 2004-236548 [Patent Document 3] Japanese Patent Publication No. 2022-050903 Summary of the Invention [Problem to be solved by the invention]
[0005] In reality, live fish swim by bending their bodies left and right by moving their heads and tails in unison. This bending posture is important not only when the fish turns, but also when swimming. By using this bending to alternately turn locally, they achieve a meandering swimming motion. In particular, the tail of the live fish is similar to a rudder at the stern of a ship, controlling the direction of propulsion and becoming an essential part for turning. However, in lures related to the prior art, the tail does not move independently, and the rear part is merely pulled by the front part. Because the rear part is oriented along the direction of the water current as it moves forward, it is difficult to achieve a posture in which the body curves on its own like a live fish. For this reason, it is difficult for lures related to the prior art to imitate the dynamic meandering swimming motion of a live fish, and it is also difficult to increase the amplitude of the meandering motion.
[0006] An object of the present invention is to provide a lure that creates dynamic movements similar to those of a live fish by curving the body of the lure. [Means for solving the problem]
[0007] In order to achieve the above object, the present invention provides A lure in which a plurality of sections including a front section, a central section, and a rear section are connected by a bending connecting section, a pair of wires connecting the front portion and the rear portion, and each wire of the pair of wires intersecting at the central portion; To provide a lure characterized by:
[0008] For example, the body of a lure has a front section corresponding to the head of the lure, a rear section corresponding to the tail of the lure, and a central section between the front and rear sections. The lure body is made of a flexible, rubber-like material. In this case, the material connecting each section is also made of the same soft material as the body, so it is also bendable.
[0009] On the other hand, if the lure body is made of a hard material such as wood or resin, hinges or chain-like connectors that can be bent can be added to the connecting parts of each part. Even when using a hard material, the angle of inclination of each part can be freely adjusted.
[0010] Furthermore, the present invention includes a wire rod that connects the front portion and the rear portion. A plurality of wire rods may be used. For example, two wire rods are paired, designated as a first wire rod and a second wire rod, respectively. The first wire rod connects the right side of the front portion and the left side of the rear portion. In addition, the second wire rod connects the left side of the front portion and the left side of the rear portion. In this way, it is also possible to treat the wire rods as a pair.
[0011] At this time, the first wire rod and the second wire rod are arranged to intersect with each other at the center portion.
[0012] In the above configuration, one pair of wires is used to connect the left and right side sections, but more than one pair of wires may be used. For example, in addition to the left and right side sections, one pair of wires may be connected to the top and bottom side sections, and four wires may be arranged to cross each other in the center.
[0013] However, when the wires cross over in the center, they may come close to each other and come into contact. Therefore, a conduit is sometimes provided for each wire in the center to prevent contact between the wires when they cross. In addition, the conduit prevents the wires from coming into contact with the material of the lure body, making it possible to reduce friction even when using a soft material with a high coefficient of friction, such as rubber. [Effects of the Invention]
[0014] According to the above-mentioned configuration, the two parts connected by the wire can be linked in motion. Also, since the wires are arranged to cross each other, the inclination direction of the two parts is the same, and the lure body can be curved.
[0015] For example, in the example configuration using the first and second wire rods, when the front portion is tilted to the left, the rear portion is also tilted to the left, creating a curved shape on the left side of the lure's body. Conversely, when the front portion is tilted to the right, the rear portion is also tilted to the right, creating a curved shape on the right side of the lure's body.
[0016] The following will specifically explain the action of each part when the lure body curves to the left relative to the traveling direction.
[0017] First, when the front section tilts to the left, the fixed point of the first wire on the right side of the front section moves away from the central section. At this time, the first wire is pulled, pulling the fixed point on the left side of the rear section to which the first wire is connected. As the fixed point on the left side of the rear section moves closer to the central section, the rear section also tilts to the left. In other words, when the front section tilts to the left, the rear section also tilts to the left, creating a curve on the left side of the lure's body.
[0018] Meanwhile, in this case, the fixed point on the left side of the front section of the second wire becomes closer to the center section. This proximity raises concerns about the second wire bending, but in reality, as the rear section tilts to the left, the right side of the rear section pulls the second wire. In other words, the movements of the first and second wires are linked, and their respective movement distances complement each other, making it difficult for the wires to bend.
[0019] Next, when the front section tilts to the right, the fixed point of the second wire on the left side of the front section moves away from the central section. At this time, the second wire is pulled, pulling the fixed point on the right side of the rear section to which the second wire is connected. As the fixed point on the right side of the rear section moves closer to the central section, the rear section also tilts to the right. In other words, when the front section tilts to the right, the rear section also tilts to the right, creating a curve on the right side of the lure's body.
[0020] As explained above, in the lure of the present invention, two or more wires are provided connecting the front section and the rear section, and the wires are arranged so that they cross each other at the center section, which links the inclination of the front section and the rear section, making it possible to create a curved shape in the body of the lure.
[0021] In the lure according to the present invention, the lure body itself creates a bend in the rear portion, so that it can achieve a dynamic posture like that of a live fish.
[0022] In addition, a turning force is created along the curved shape of the lure, so even when the lure is pulled through the water, it is accompanied by a swinging motion due to the turning force, resulting in a dynamic swimming motion. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0024] Next, embodiments of the present invention will be described with reference to the drawings. As an example of a first embodiment of the present invention, Fig. 1 shows a plan view perspective view of a lure body as seen from the back. In the lure according to the present invention, the lure body, which resembles a fish, comprises a front section 11, a central section 12, and a rear section 13. Between adjacent sections, there are provided connecting sections that bend to allow each section to move. In Fig. 1, there is a connecting section 21 between the front section 11 and the central section 12, and a connecting section 23 between the central section 12 and the rear section 13. In the embodiment shown in Figure 1, the lure body is made of a soft, rubber-like material, and the same material is used for each of the sections 11, 12, and 13 and the connecting sections 21 and 23, which are integrally molded. Because the connecting sections are also made of a flexible soft material, each section can be tilted independently. The lure body may be made of a hard material such as acrylic resin or plastic, rather than the soft material used in the embodiment of Figure 1. However, if the lure body is integrally molded from a hard material, the connecting portions will also be made of a hard material, making them difficult to bend. Therefore, when a hard material is used, soft materials or bendable connectors such as hinges may be used locally for the connecting portions 21 and 23. The lure configurations described above use conventional technology, and are also disclosed in Patent Documents 1 to 3, for example.
[0025] In the present invention, a pair of wires is further provided connecting the side portions of the front region 11 and the side portions of the rear region 13, and the wires are arranged to cross each other at the central region 12. The lure of FIG. 1 has fixed points 31a and 32a on the right and left sides of the front region 11, respectively, and fixed points 32b and 31b on the right and left sides of the rear region 13, respectively, with fixed points 31a and 31b connected by wire 31, and fixed points 32a and 32b connected by wire 32. Wires 31 and 32 cross each other at the central region 12.
[0026] Wires 31 and 32 are connected to the front portion 11 and the rear portion 13, respectively. Therefore, when the front portion tilts and the fixed points 31a and 32a move, force is transmitted via wires 31 and 32 to fixed points 31b and 32b in the rear portion. The wires 31 and 32 are preferably made of a material with low friction resistance and low stretchability, and may be made of, for example, nylon thread or a wire coated with nylon resin.
[0027] Wires 31 and 32 cross each other at the center and are in close proximity. To prevent the wires from coming into contact and rubbing against each other when they cross, wires 31 and 32 are routed through conduits 31c and 32c, respectively, in Figure 1 . Conduits with a larger inner diameter than the wires and smooth inner walls are preferred. In the embodiment shown in Figure 1 , conduits made of plastic, which has a low coefficient of friction within the conduit, are used. These conduits 31c and 32c prevent direct contact between wires 31 and 32 and the material of central region 12, even if the material of central region 12 has a high coefficient of friction, ensuring smooth movement of wires 31 and 32. If the central region is made of a hard material such as acrylic resin or plastic, the same effect can be achieved by simply providing a through-hole with a smooth inner wall in the conduit.
[0028] Fig. 2 is a side perspective view of the lure in Fig. 1 as seen from the left side, and Fig. 3 is a side perspective view of the lure in Fig. 1 as seen from the front. In Fig. 2 and Fig. 3, the wiring pipes 31c and 32c shown in the perspective views are each bent in the center, and the paths of the wiring pipes do not overlap. 2 and 3, it is clear that a feature of the appearance of the lure of this embodiment is that a portion of the wire rods 31 and 32 is exposed between the front portion 11 and the central portion 12, and between the central portion 12 and the rear portion 13, respectively.
[0029] The operation of each part when the front part 11 and the rear part 13 of the lure in Fig. 1 are linked together will be explained below using the planar perspective view in Fig. 4. In Fig. 4, (a) is an explanatory diagram of a state in which the front part 11 is not tilted, and (b) is an explanatory diagram of a state in which the front part 11 is tilted. In the state (a), the front region 11 is not tilted and faces in the same direction as the center line of the central region 12. At this time, the center line of the rear region 13 is also not tilted and faces in the same direction as the center line of the central region 12. In other words, in the state (a), none of the regions are tilted and the lure body is straight. Next, (b) illustrates the case where the front region 11 tilts to the left. As shown in (b), when the front region 11 tilts to the left of the lure body around the connecting portion 21, the fixed point 31a moves, and the wire 31 connected to the fixed point 31a is pulled. The wire 31 transmits tension to the rear region 13 via the wire conduit 31c in the center region 12, and the fixed point 31b also moves. As the fixed point 31b moves, the rear region 13 also tilts along a circular orbit centered on the connecting portion 23. At this time, in the state of (b), both the front portion 11 and the rear portion 13 are inclined to the left side of the body, and a curved shape of the lure body is generated.
[0030] Next, the relationship between the inclination angles of the front region 11 and the rear region 13 will be explained using Figure 5. Figure 5 is a planar perspective view that extracts elements related to the inclination of the front region 11 and the rear region 13 in the lure shown in Figure 1 and, as an example, is specialized for explaining the function of the wire rod 31. (a) is an explanatory diagram of a state in which the front region 11 is not inclined, and (b) is an explanatory diagram of a state in which the front region 11 is inclined. In (a), the fixed point 31a of the front region 11 is located on a rotational orbit 21a of radius r1, centered on the center point 21c of the connecting part 21. Similarly, the fixed point 31b of the rear region 13 is located on a rotational orbit 23a of radius r3, centered on the center point 23c of the connecting part 23. Next, when the front portion 11 tilts with a tilt angle Θ1, the fixed point 31a also moves along the rotational path 21a in an arc, as shown in (b). The moving distance of the fixed point 31a corresponds to the length of the arc of the rotational path 21a, and is the product of the radius r1 and the tilt angle Θ1, i.e., r1 × Θ1. The movement distance L of the wire 31 is caused by the movement of the fixed point 31a, and is therefore approximately equal to r1xΘ1, and the approximate expression (1) is obtained.
[0031] (Number 1) L ≒ r1 × Θ1 ··· (1) formula The reason why Equation (1) is an approximation is that the path of the wire 31 does not match the arc of the rotational orbit 21a. Since the shape of the wire 31 beyond the fixed point 31a is a straight line, strictly speaking, it does not match the moving distance of the arc. However, as shown in Figure 5, when the path of the wire 31 is close to the rotational orbit 21a and the inclination angle Θ1 is small, the error of the approximation is small. Since the movement of the fixed point 31b of the rear portion 13 is brought about by the movement distance L of the wire 31, the approximate formula (2) can be obtained.
[0032] (Number 2) L ≒ r3 × Θ3 ··· (2) formula In formula (1) and formula (2), the moving distance L of the wire 31 is equal, so that the inclination angle Θ3 of the rear portion 13 is approximated by formula (3).
[0033] (Number 3) Θ3 ≒ r1 / r3 × Θ1 ··· Equation (3) In other words, in the lure of Figure 1 according to the present invention, by setting the ratio between the radius r1 of the rotational path 21a of the front portion 11 and the radius r3 of the rotational path 23a of the front portion 13, the ratio between the inclination angle Θ1 of the front portion 11 and the inclination angle Θ3 of the rear portion 13 can be freely changed.
[0034] For example, if you want to make the inclination angle Θ3 of the rear region 13 larger than the inclination angle Θ1 of the front region 11, and thereby increase the movement of the rear region 13, this can be achieved by making the radius r3 of the rear region 13 smaller than the radius r1 of the front region 11.
[0035] Fig. 6 shows an example in which the radius r1 of the rotational orbit of the front region and the radius r3 of the rotational orbit of the rear region are different. Fig. 6 is an explanatory diagram in which the radius r3 of the rear region 13 in Fig. 5 is made smaller than the radius r1 of the front region 11. (a) shows a state in which the front region is not tilted, and (b) shows a state in which the front region is tilted. In (b), when the front portion 11 is tilted with a tilt angle Θ1, the wire 31 moves, and the movement distance L is the same as that described in FIG. 5. On the other hand, in the case of FIG. 6, the radius r3 of the rear portion 13 is set small. Therefore, in order for the fixed point 31b of the rear portion 13 to move the same distance as the movement distance L of the wire 31, the tilt angle Θ3 of the rear portion 13 becomes large. As shown in FIG. 6, the tilt angle Θ3 of the rear portion 13 can be made larger than that of the front portion 11.
[0036] As explained above, in the lure of the first embodiment of the present invention shown in FIG. 1, the inclination of the front and rear portions is linked, and the inclination angles of the front and rear portions can also be freely set.
[0037] FIG. 7 shows a more practical version of the lure shown in FIG. 1 , further equipped with a fishing hook 41 for catching fish and a connecting portion 42 for towing the lure from an external fishing line. In FIG. 7 , the fishing hooks 41 are attached to the center section 12 and the underside of the rear section 13. Because the fishing hook 41 is made of metal and has a high specific gravity in water, it also serves to stabilize the posture of the lure body. Furthermore, a semi-annular metal connecting portion 42 is attached to the tip of the front section 11. By externally pulling the fishing line attached to the connecting portion, the lure body is pulled and propelled. At the same time, the external pulling force via this connecting portion 42 is one of the factors that control the tilt of the front section 11. FIG. 8 shows a perspective view of the lure shown in FIG. 7 .
[0038] FIG. 21 is a photograph showing a prototype example of the lure of FIG. 8 according to the first embodiment of the present invention, viewed obliquely. In this prototype, the lure body, including the connecting portion, is made of flexible and elastic silicone rubber. Wiring tubes 31c and 32c are provided in the center for passing wires 31 and 32 through. In this prototype, the body is uncolored, and black wires are used for wires 31 and 32 to improve visibility. When this lure is viewed obliquely, as shown in FIG. 19, parts of wires 31 and 32 and the opening of wiring tube 32c can be seen on the side of the lure body.
[0039] Figure 22 is a photograph showing the prototype lure of Figure 21 as seen from the back of the lure body. (a) is an explanatory diagram of the state in which the front part is not tilted, and (b) is an explanatory diagram of the state in which the front part is tilted. Note that when taking these photographs, the lure body was fixed at the center and tilted by pulling the fishing line connected to the front end of the front part from the outside.
[0040] In Figure 22, it is clear that when the fishing line is pulled (b), the front and rear parts each deviate from the reference line, causing the torso to bend, compared to when the fishing line is not pulled (a). As described above, using the prototype example shown in FIGS. 21 and 22, it was verified that the operating mechanism described in the present invention with reference to FIGS. 1 to 8 was provided.
[0041] Figure 9 is a plan view showing the swimming motion of the lure in Figure 8 when it is towed in water, and it progresses in the order of (a) to (g). The following explains the motion of the lure in each of (a) to (g). (a) shows the state immediately after being dropped into the water, and the direction of the lure's body is not necessarily aligned with the direction of travel. The lure is not yet being towed, so the lure's body is not curved. (b) is the state in which pulling begins from the state in (a). The lure's position moves away from the center line. Meanwhile, the pulling force causes the front of the lure to face in the direction of travel, and the left side of the lure's body curves. A turning force is generated along this curve. In (c), the turning force has caused the lure to move closer to the centerline from the position in (b). Meanwhile, the lure's body is now positioned away from the direction of travel, so water pressure acts against the pulling force on each part of the lure. (d) When the lure is continuously pulled from the state (c), the curve of the lure body is released due to the pulling force applied to the front part and the water pressure applied to the middle and rear parts. In (e), the lure continues to be pulled from the state in (d), and its position moves away from the center line. Meanwhile, the pulling force causes the front of the lure to face the direction of travel, and the right side of the lure's body curves. A turning force is generated along the curve. (f) shows the state in which the lure has moved closer to the centerline from the position in (e) due to the turning force. Meanwhile, the lure's body is now in a position that deviates from the direction of travel, so water pressure acts against the pulling force on each part of the lure. (g) When the lure is continued to be pulled from the state of (f), the curve of the lure body is released due to the pulling force received by the front part and the water pressure received by the central part and the rear part.
[0042] As explained above in (a) to (g), by using the lure shown in Figure 8, a serpentine swimming motion can be obtained when towed in water.
[0043] In particular, the lure shown in Figure 8 is characterized by the curved movement of the lure's body when towed through the water. This means that it can move more dynamically than conventional lures, which are only towed at the rear. The lure shown in Figure 8 is also characterized by a curved shape that generates a turning force due to the inclination of the front and rear sections. This allows for a larger amplitude of meandering swimming motion than conventional lures, which do not have an inclined rear section.
[0044] Next, Fig. 10 to Fig. 12 are shown as an example of a second embodiment of the present invention. Fig. 10 is a plan perspective view of a lure according to the second embodiment of the present invention as seen from the back, Fig. 11 is a side perspective view of the lure of Fig. 10 as seen from the left side, and Fig. 12 is a side perspective view of the lure of Fig. 10 as seen from the front.
[0045] The lure of the second embodiment shown in Figures 10 to 12 is characterized in that the shape of connecting portions 21, 23 of the lure of the first embodiment described in Figures 1 to 6 is changed to connecting portions 26, 28, and further a pair of wires 33, 34 are added to connect the upper and lower portions of front region 11 to the upper and lower portions of rear region 13. In lure connecting portions 26, 28 of the second embodiment, front region 11 and rear region 13 are shaped to be more easily bent in the vertical direction than connecting portions 21, 23 of the lure of the first embodiment. Furthermore, the front region 11 is provided with fixing points 33a and 34a, and the rear region 13 is provided with fixing points 33b and 34b, and these fixing points are connected diagonally by wires 33 and 34 via conduits 33c and 34c provided in the central region 12. For example, when the tip of the front region tilts downward, the tension of wire 33 causes the rearmost portion of the rear region to tilt downward, resulting in a curved lower portion of the lure body. Conversely, when the tip of the front region tilts upward, the tension of wire 34 causes the rearmost portion of the rear region to tilt upward, resulting in a curved upper portion of the lure body. With the above-described configuration, the lure shown in Figures 10 to 12 can obtain a curved state in the up and down direction in addition to the left and right curved state of the lure body shown in the first embodiment, and can obtain a dynamic movement in which the body is freely curved up, down, left, and right.
[0046] In the following, in order to clarify the effect of the lure according to the second embodiment of FIG. 10, the difference in swimming behavior between the lure according to the first embodiment, which cannot be bent in the vertical direction, and the lure according to the second embodiment, which can be bent in the vertical direction, will be explained using FIG. 13 and FIG. 14.
[0047] First, a side view showing the state when the lure according to the first embodiment of Fig. 8 is pulled in water will be described using Fig. 13. Fig. 13 progresses in the order of (a) to (d), and each state will be described below. (a) shows the state immediately after the lure is dropped into the water, where it sinks under its own weight. (b) From the state of (a), pulling begins via the fishing line, and the lure body faces in the direction of pulling. In (c), the lure continues to be pulled from the state in (b), and although the water depth becomes shallower as the lure moves in the direction of travel, the posture of the lure's body does not change from (b). (d) is an explanatory diagram showing that the lure is being pulled further from the state in (c), the water depth becomes shallower, but the posture of the lure's body does not change from (b). In other words, in the case of the lure of Figure 8 according to the first embodiment, which does not bend in the vertical direction, the lure body simply moves in a straight line in the direction of travel while maintaining the same posture, as shown in Figures 13(b) to 13(d).
[0048] Next, a side view showing how the water depth changes when the lure according to the second embodiment of Fig. 10 is towed in water will be described using Fig. 14. Fig. 14 progresses in the order of (a) to (g), and each state will be described below. (a) shows the state immediately after the lure is dropped into the water, where it sinks into the water under its own weight. (b) shows the state in which pulling begins via the fishing line from the state in (a), and the pulling force causes the front part of the lure to tilt in the direction of travel, causing the lure body to bend upward. (c) shows the state in (b) where the lure is being pulled further, and the curved state causes a turning force to act on the lure's body towards the water surface. This force towards the water surface causes the water depth to become shallower. Meanwhile, as the lure's body starts to turn, the water pressure on the lure's body begins to increase. (d) shows the state in which traction continues from the state in (c), and the water pressure pushes each part, changing the inclination and releasing the curve. (e) shows the state in which the pulling force continues from the state in (d), and a pulling force acts on the front part in the direction of travel, causing the curve of the lure's body to reverse downward. (f) shows the state in (e) where the lure is being pulled further, and the bending of the lure creates a turning force, causing the lure to move in a direction that leads to deeper water. Meanwhile, as the lure's body turns, the water pressure on the lure's body begins to increase. (g) shows a state in which traction continues from the state in (f), and the inclination of each part changes due to the traction force on the front part and the water pressure on the central and rear parts, and the curved state is released. That is, in the case of the lure of Fig. 10 according to the second embodiment, which can be bent in the vertical direction, the lure body moves dynamically, bending in the vertical direction, as shown in Fig. 14(b) to (g). At the same time, a turning force in the vertical direction is generated along the bending state, so swimming with a swinging motion in the water depth direction is obtained.
[0049] Next, FIG. 15 shows an example of a third embodiment of the present invention. In a lure according to the present invention, the lure body is not limited to the three sections of the front section 11, the central section 12, and the rear section 13 shown in FIGS. 1 to 14, but may include multiple sections. Therefore, FIG. 15 shows an example of a lure body structure consisting of four sections, with the central section 12 of the lure body shown in FIG. 1 being divided into a first central section 12a and a second central section 12b. A flexible connecting section 22 is also provided between the first central section 12a and the second central section 12b, allowing each of the four sections to be freely tilted. Wiring tubes for routing wires 31 and 32 are provided in the central sections 12a and 12b, and the wires are arranged to cross each other in each of the central sections 12a and 12b. Because the wires cross twice, the wires 31 and 32 are connected to the same side of the front region 11 and the rear region 13, respectively. In other words, the right side of the front region 11 is connected to the right side of the rear region 13 by the wire 31, and the left side of the front region 11 is connected to the left side of the rear region 13 by the wire 32. Note that although the lure in FIG. 15 shows a case where the wires cross twice, if the number of crossings is even, the connection relationship between the wires 31 and 32 in the front region 11 and the rear region 13 will be the same as in the case of two crossings.
[0050] 15, the fixing points 31b and 32b of the wires 31 and 32 in the rear portion 13 are positioned closer to the center of the connecting portion 23 than in the lure in FIG. 1. In addition, the openings of the wiring tubes provided in the central portions 12a and 12b are also positioned closer to the centers of the connecting portions 21 and 22. In particular, the lure of Figure 15 has more bending points than the lure of Figure 1 due to the provision of connecting portion 22 in central portion 12. For this reason, bending one portion of connecting portion 21 must also bend two portions of connecting portions 22 and 23. In order to efficiently transmit the bending of connecting portion 21 to connecting portions 22 and 23, the relationship shown in equation (3) above was used to set the turning orbit radius of connecting portions 22 and 23 to be smaller than that of connecting portion 21.
[0051] Next, using Figure 16, we will explain how the state of the lure body changes when the front portion 11 of the lure of Figure 15 is tilted. (a) is an explanatory diagram of a state in which the front portion is not tilted, and (b) is an explanatory diagram of a state in which the front portion is tilted. Note that, in Figure 16, as in the explanations of Figures 5 and 6 above, lines 21a, 22a, and 23a are added to indicate the rotational paths of the respective fixed points and the opening of the conduit when the connecting portions 21, 22, and 23 are centered. As shown in Figure 16, in the lure of Figure 15, the radii r2 and r3 of the rotational paths of the connecting portions 22 and 23 are smaller than the radius r1 of the rotational path of the connecting portion 21. When the inclination angles at which the connecting portions 21, 22, and 23 bend are Θ1, Θ2, and Θ3, respectively, the following approximate formula (4) is obtained.
[0052] (Number 4) r1 × Θ1 ≒ r2 × Θ2 + r3 × Θ3 ··· (4) Formula The left side of equation (4) represents the movement distance of the wire at connecting portion 21 caused by the inclination of front portion 11, and the right side of equation (4) represents the movement distance of the wire required to bend connecting portions 22 and 23. In other words, the movement distance r1xΘ1 of the wire at one location at connecting portion 21 must be distributed to two locations at connecting portions 22 and 23 by r2xΘ2 and r3xΘ3, respectively. For example, if r2 and r3 are each half of r1 and Θ2 and Θ3 are equal, the following approximate equation (5) is obtained.
[0053] (Number 5) Θ1 ≒ Θ2 ≒ Θ3 ··· Equation (5) In other words, as in the lure shown in Figure 15, by setting the radius of rotation of connecting parts 22 and 23 to be smaller than the radius of rotation of connecting part 21, for example, half of it, the same inclination angle can be obtained at all connecting parts, as shown in equation (5).
[0054] When the front part 11 is tilted, tension is applied to the wire 31, the connecting parts of each part are bent, and the left side of connecting part 22 and the right side of connecting part 23 are contracted, as shown in Figure 16(b). The bending of the body is similar to an S-shaped curve. Because the entire lure body is not curved in the same direction, it is difficult to achieve a rotational swimming motion like the lure in Figure 1. However, by bending multiple connecting parts into an S-curve, it is possible to create a lure that can create a dynamic posture that is close to a curve.
[0055] Next, FIG. 17 shows an example of a fourth embodiment of the present invention. While the lures in FIGS. 1 to 16 all show examples in which the wires cross each other, lures according to the present invention may have a configuration in which the wires do not cross each other, or may have a configuration including a portion in which the wires do not cross each other. In the lure shown in FIG. 17, the arrangement of the wires 31, 32 in the central region 12b and the rear region 13 is different from that of the lure shown in FIG. 15. That is, the wires 31, 32 in the central region 12b do not cross each other. Furthermore, in the rear region 13, the wire 31 is connected to a fixed point 31b on the left side, and the wire 32 is connected to a fixed point 32b on the right side. Because there is only one crossing in the central region 12, the connection relationship of the wires 31, 32 in the front region 11 and the rear region 13 is the same as that of the lure shown in FIG. 1. In the lure of Figure 17, the wires cross once, but if the number of crossings is odd, the connection relationship between the wires 31, 32 in the front portion 11 and the rear portion 13 will be the same as in the case of one crossing.
[0056] Next, using Figure 18, we will explain how the state of the lure body changes when the front region 11 of the lure in Figure 17 is tilted. Figure 18(a) is an explanatory diagram of a state in which the front region is not tilted, and Figure 18(b) is an explanatory diagram of a state in which the front region is tilted. When the front region 11 is tilted, as shown in Figure 18(b), tension is applied to the wire 31, causing it to bend at the connecting portions of each portion, and the left side of connecting portions 22 and 23 contracts, creating a curved state on the left side of the lure body. In addition, because the multiple connecting portions create a curved shape, it is possible to provide a lure that can achieve a dynamic posture and meandering swimming motion that is more similar to that of a live fish than the lure in Figure 1.
[0057] Next, Fig. 19 shows an example of a fifth embodiment of the present invention. The lures in Figs. 1 to 18 all show examples of configurations in which pairs of wires are used in each section, but in lures according to the present invention, it is not necessary to use pairs of wires, for example, when the number of sections of the lure body is small and the friction between the wires and the wiring tube is small. In the lure shown in Fig. 19, the lure body is composed of two sections, a front section 11 and a rear section 13, and there is only one connecting section.
[0058] Since there is only one connecting part, the wire length can be shortened, which reduces the load caused by friction with the wiring pipe when the wire moves. Therefore, the lure shown in Figure 19 does not use a pair of wires as shown in Figures 1 to 18, but is configured with only one wire 31 arranged in a Z-shape as shown in Figure 19.
[0059] Next, using Figure 20, we will explain how the state of the lure body changes when the front region 11 of the lure in Figure 19 is tilted. Figure 20(a) is an explanatory diagram of a state in which the front region is not tilted, Figure 20(b) is an explanatory diagram of a state in which the tip of the front region is tilted to the left of the body, and Figure 20(c) is an explanatory diagram of a state in which the tip of the front region is tilted to the right of the body. When the tip of the front region 11 is tilted to the left of the body, the gap between the front region 11 and the rear region 13 expands on the right side of the lure body, as shown in Figure 20(b). As this gap expands, the tension in the wire 31 causes the gap between the front region 11 and the rear region 13 on the left side of the lure body to contract, resulting in a curved state. Conversely, when the tip of the front region 11 is tilted to the right of the body, as shown in Figure 20(c), the gap on the left side of the lure body expands, and the right side of the lure body contracts via the tension in the wire 31. That is, the lure shown in FIG. 19 can achieve bending on either the left or right side of the lure body, as shown in FIG. 20, even though it has a simple structure that does not use a symmetrical pair of wire rods.
[0060] In the above explanation of the first to fifth embodiments of the present invention, it has been shown that by using wires and wire pairs to link parts together, the posture of the lure body can be changed, creating a dynamic movement similar to that of a live fish. Furthermore, it has been shown that the present invention can be applied to lures with various numbers of body parts as long as they have connecting parts. [Industrial Applicability]
[0061] The lure according to the present invention is expected to be useful as a fishing lure or as a fishing tackle for those who enjoy fishing as a hobby. [Explanation of symbols]
