Description

[Technical Field]

[0001] The present invention relates to a lure. [Background technology]

[0002] For example, Patent Document 1 discloses a lure that includes a lure body, a weight housed inside the lure body, and an elastic member disposed behind the weight. When the lure is cast and the weight moves backward, the elastic member biases the weight back to its original position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-90632 Summary of the Invention [Problem to be solved by the invention]

[0004] The lure disclosed in Patent Document 1 requires the weight to be pushed forward from the rear by an elastic member, so the elastic member is set to be strong. As a result, the weight returns to the front during flight after casting, and the center of gravity also shifts from the rear to the front. This causes the lure to lose speed and lose balance, resulting in a problem of reduced casting distance.

[0005] The present invention has been made to solve the above problems, and an object of the present invention is to provide a lure that can increase the flight distance when cast. [Means for solving the problem]

[0006] The lure of the present invention comprises a main body having a hollow movement space, a first weight disposed in the movement space, a second weight disposed behind the first weight in the movement space, and an elastic member disposed between the first weight and the second weight, wherein the first weight, the second weight, and the elastic member are disposed so as to be movable within the movement space.

[0007] According to the present invention, since the weight is divided into a first weight and a second weight with an elastic member sandwiched therebetween, it is possible to prevent all of the weights from unintentionally returning forward during flight when casting. This prevents the center of gravity from shifting forward during flight and causing the lure to stall, thereby increasing the casting distance.

[0008] It is also preferable that the vehicle further includes a shaft member arranged along the front-rear direction of the movement space, and that the first weight, the second weight, and the elastic member are arranged to be able to move along the shaft member.

[0009] According to the present invention, the first weight, the second weight, and the elastic member move along the shaft member, allowing for smooth movement. In addition, the design freedom for the shapes of the first weight and the second weight can be increased.

[0010] It is also preferable that the first weight, the second weight and the elastic member are spherical.

[0011] It is also preferable that the first weight, the second weight, and the elastic member are spherical and move within the movement space.

[0012] According to the present invention, the first weight and the second weight are spherical and can move by rolling within the movement space, so that members for moving the first weight and the second weight can be omitted, thereby reducing the number of parts.

[0013] Moreover, it is preferable that the first weight is heavier than the second weight.

[0014] According to the present invention, the first weight is more likely to return to the front when the lure hits the water, which allows for quicker action activation and improved maneuverability.

[0015] It is preferable that a magnetic body is provided within the main body portion, and the second weight is attracted to the magnetic body, thereby holding the first weight, the second weight, and the elastic member so that the center of gravity is located forward of the main body portion.

[0016] According to the present invention, the center of gravity of the lure can be fixed at the front, and the swimming posture after landing on water can be stabilized.

[0017] The first weight is preferably made of a non-magnetic metal.

[0018] According to the present invention, when the first weight moves forward, it is possible to prevent the movement from being obstructed by being attracted to the magnetic body, and the action can be initiated more quickly.

[0019] The outer diameter of the second weight is preferably larger than the outer diameter of the first weight.

[0020] According to the present invention, the adhesive force of the second weight to the magnetic body is increased, reducing the possibility of separation due to vibrations, etc., and making it possible to more stabilize the swimming posture after landing on water. [Effects of the Invention]

[0021] According to the present invention, a lure that can increase the flight distance when cast is provided. [Brief explanation of the drawings]

[0023] First Embodiment

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated explanations will be omitted as appropriate. In the following description, "front and back" and "up and down" follow the arrows in Figure 1. Note that these directions are used for convenience of explanation and do not limit the directions of the present invention.

[0025] The lure 1 according to this embodiment is a lure in which the position of the center of gravity changes as the weight (sinker) moves in the front-to-rear direction. As shown in Fig. 1, the lure 1 according to this embodiment includes a main body 2, a first weight 3, a second weight 4, an elastic member 5, a magnetic body 6, and a shaft member 7.

[0026] As shown in FIG. 1, the main body 2 is shaped like a fish. The height dimension of the central part (belly part) of the main body 2 is greatest, and the height dimension gradually decreases toward the rear. The main body 2 is made of a synthetic resin material such as ABS (Acrylonitrile Butadiene Styrene), polycarbonate, or polyvinyl chloride. However, the main body 2 may be made of other materials. For example, the main body 2 may be made of metal such as lead, brass, tungsten, or stainless steel, or may be made of wood.

[0027] The main body 2 is hollow, forming a hollow movement space 2a in which weights (first weight 3, second weight 4) described below move in the front-to-rear direction. A lip 2b that protrudes forward and receives water resistance is formed at the bottom of the front end of the main body 2. A front eye attachment portion 2c is formed behind the lip 2b, and a rear eye attachment portion 2d is formed at the rear end of the main body 2. A line eye attachment portion 2e is formed at the front end of the main body 2 to which a line eye is attached. The front eye attachment portion 2c, the rear eye attachment portion 2d, and the line eye attachment portion 2e are grooves in which each eye P is attached.

[0028] The first weight 3 is a cylindrical weight member. The first weight 3 is made of a non-magnetic, high-density metal that is not attracted to a magnet. Examples of non-magnetic, high-density metals include tungsten, molybdenum, copper, silver, and lead. The first weight 3 is disposed in front of the second weight 4 in the movement space 2a. The first weight 3 may have any shape and can be set appropriately, but in this embodiment, the first weight 3 is formed to be heavier than the second weight 4.

[0029] The second weight 4 is a cylindrical weight member. The second weight 4 is made of a magnetic material that is attracted by magnetic force. Examples of magnetic materials include iron, cobalt, and nickel. The second weight 4 is disposed behind the first weight 3 in the movement space 2a. The second weight 4 may have any shape and can be set appropriately, but in this embodiment, the outer diameter of the second weight 4 is larger than the outer diameter of the first weight 3.

[0030] The shapes of the first weight 3 and the second weight 4 can be set as appropriate. In this embodiment, the first weight 3 and the second weight 4 are both cylindrical, but they may have different shapes. For example, the first weight 3 may be a square prism and the second weight 4 may be cylindrical.

[0031] The elastic member 5 is an elastic member disposed between the first weight 3 and the second weight 4. The elastic member 5 is, for example, a spring member, a rubber member, or the like. The elastic force of the elastic member 5 is set so that it comes into contact with the first weight 3 during flight when cast, absorbing any rearward movement of the first weight 3 and preventing the first weight 3 from moving forward during flight.

[0032] The magnetic body 6 is ring-shaped and is a material that can be magnetized. The magnetic body 6 is made of, for example, iron oxide, chromium oxide, cobalt, nickel, ferrite, or gadolinium. The magnetic body 6 is a member that attracts the second weight 4 by magnetic force and maintains the position of the second weight 4. The magnetic body 6 may be located in any position as long as it can fix the second weight 4 so that the center of gravity of the main body 2 is located forward. In this embodiment, the magnetic body 6 is located above the shaft member 7 and slightly forward of the center of the shaft member 7 in the front-to-rear direction.

[0033] In the movement space 2a, a rod-shaped shaft member 7 is disposed between the front eye attachment portion 2c and the rear eye attachment portion 2d. The first weight 3, the second weight 4, and the elastic member 5 are inserted through the shaft member 7 and are disposed so as to be movable in the front-rear direction. Cushioning members 7a, 7b are disposed at the front and rear ends of the shaft member 7. The cushioning members 7a, 7b may have any shape or material as long as they can absorb impact when the first weight 3 and the second weight 4 move forward or backward. In this embodiment, the cushioning members 7a, 7b are formed in a ring shape from a resin material.

[0034] In this embodiment, the first weight 3 is disposed in the front, the second weight 4 is disposed in the rear, and the elastic member 5 is disposed between the first weight 3 and the second weight 4, but another elastic member may be disposed behind the second weight 4. Furthermore, another weight may be disposed behind the elastic member, and a configuration in which three or more weights are disposed may be adopted.

[0035] Next, the operation of the fishing lure 1 of this embodiment will be described. Figure 2 shows the flying posture when cast. As shown in Figure 2, during flight when cast, the fishing lure 1 assumes a posture in which the front side is raised and the lower side is lowered. At this time, the first weight 3, the second weight 4, and the elastic member 5 are arranged at the rear of the main body 2 (the rear end of the shaft member 7) due to inertia. Furthermore, the elastic member 5 is in a contracted state due to the weight of the first weight 3. It is preferable that the flying posture of the fishing lure 1 be maintained in this state.

[0036] FIG. 3 shows the state of the lure 1 immediately after it hits the water. When the lure 1 hits the water, centrifugal force causes the rear of the lure 1 to land first. When the lure 1 hits the water, the impact of the water landing acts on the rear of the lure 1, and the restoring force of the elastic member 5 also acts. As a result, the first weight 3 is pushed forward and moves to the front of the main body 2 (the front end of the shaft member 7). At this time, because the first weight 3 is heavier than the second weight 4, the center of gravity of the main body 2 moves forward. As a result, the lure 1 quickly tilts downward and forward. As the lure 1 tilts downward and forward, the second weight 4 and the elastic member 5 also move along the shaft member 7 toward the first weight 3.

[0037] 4 shows the state in which a user reels in the fishing line and reels in the lure 1. After the first weight 3, the second weight 4, and the elastic member 5 move forward, the second weight 4 is maintained in position by being attracted by the magnetic force of the magnetic body 6. In other words, since the position of the second weight 4 is maintained, the first weight 3, the second weight 4, and the elastic member 5 do not move backward. Therefore, the lure 1 can be made to swim while maintaining a forward leaning posture.

[0038] In the lure 1 of the present embodiment described above, the weights (first weight 3, second weight 4) are separated by the elastic member 5, so it is possible to prevent all of the weights from unintentionally returning forward during flight when cast. This prevents the center of gravity from shifting forward during flight and causing the lure 1 to stall, thereby increasing the casting distance. In other words, when the lure is first cast (the moment the lure is thrown out), the two weights (first weight 3, second weight 4) and the elastic member 5 are pressed against the rear end all at once. For a moment, the first weight 3 quickly and strongly compresses the elastic member 5. This repulsion creates a "pushing force" that pushes the lure 1 forward. The momentum of the lure 1, which keeps it flying without stalling because the second weight 4 and the elastic member 5 remain at the rear, creates a "force toward the rear end (direction of flight)." These two forces cancel each other out, causing the first weight 3 to fly while being loosely pressed against the elastic member 5. As the lure 1 subsequently stalls, the first weight 3 maintains its rear center of gravity while still loosely pressing against the elastic member 5 (while the first weight 3 remains at the rear end), allowing it to continue flying. This allows the lure 1 to achieve its maximum flight distance before landing. Then, due to the strong impact of the lure landing, the first weight 3 again presses strongly against the elastic member 5, making it more likely to move forward due to the repulsion. Even if the first weight 3 moves forward during flight, the second weight 4 and the elastic member 5 are positioned rearward. In other words, since all of the weights are not biased forward during flight, the lure 1 can be prevented from tilting forward during flight.

[0039] The lure 1 also includes a shaft member 7 that is disposed along the front-to-rear direction of the movement space 2a, and the first weight 3, the second weight 4, and the elastic member 5 move along the shaft member 7. This allows the first weight 3, the second weight 4, and the elastic member 5 to move smoothly in the front-to-rear direction of the main body 2. Furthermore, because the first weight 3 and the second weight 4 only need to move along the shaft member 7, there are fewer restrictions on their shapes, and the degree of freedom in designing the first weight 3 and the second weight 4 can be increased.

[0040] In addition, since the first weight 3 is heavier than the second weight 4, the first weight 3 is more likely to return to the front. This allows for quicker action activation, improving operability.

[0041] Furthermore, a magnetic body 6 is provided inside the main body 2. By attracting the second weight 4 to this magnetic body 6, the first weight 3, the second weight 4, and the elastic member 5 can be held so that the center of gravity is located on the front side of the main body 2, thereby maintaining the center of gravity of the lure 1 on the front side. This allows the lure to maintain a stable swimming posture after landing on water.

[0042] Furthermore, since the first weight 3 is made of a non-magnetic metal, it is not attracted to the magnetic body 6 when it moves forward, which prevents the movement of the first weight 3 from being hindered and allows the action to be initiated more quickly.

[0043] Additionally, the outer diameter of the second weight 4 is larger than the outer diameter of the first weight 3. In other words, by increasing the outer diameter of the second weight 4 and reducing the distance from the magnetic body 6, the attraction force to the magnetic body 6 is increased, reducing the possibility of separation due to vibrations, etc., and enabling a more stable swimming posture after landing on water.

[0044] Second Embodiment Next, a lure according to a second embodiment will be described. As shown in Fig. 5, the second embodiment differs from the first embodiment in the shapes of the movement space, the first weight, the second weight, and the elastic member. The second embodiment will be described focusing on the differences from the first embodiment.

[0045] The movement space 20A of this embodiment differs from the first embodiment in that it is a space covered by a wall portion 30 and a portion of the main body portion 2. The wall portion 30 includes an upper portion 31, a rear end portion 32, a lower portion 33, an upper inclined portion 34, a lower inclined portion 35, and a pair of side walls (not shown). The upper portion 31 and the lower portion 33 extend along the front-to-rear direction of the main body portion 2. The upper portion 31 and the lower portion 33 are spaced apart enough to allow movement of a first weight 3A, a second weight 4A, and an elastic member 5A (described later). The rear ends of the upper portion 31 and the lower portion 33 are connected by the rear end portion 32. The front of the upper portion 31 is connected to the upper inclined portion 34, and the front of the lower portion 33 is connected to the lower inclined portion 35. The upper inclined portion 34 and the lower inclined portion 35 extend downward (toward the ventral side) of the main body portion 2. In other words, the movement space 20A is divided into a straight portion and an inclined portion. The movement space 20A may be configured with only straight portions, omitting the inclined portions. In this case, the upper inclined portion 34 and the lower inclined portion 35 are omitted, and a wall portion is provided connecting the front ends of the upper portion 31 and the lower portion 33, making the movement space 20A rectangular in cross section.

[0046] The first weight 3A is a spherical weight member that is formed so that it can move forward and backward by rolling within the movement space 20A. The first weight 3A is formed of a non-magnetic, high-density metal that is not attracted to magnets. The first weight 3A is disposed in front of the second weight 4A in the movement space 2A. The size and weight of the first weight 3A can be set as appropriate, but in this embodiment, the first weight 3A is formed to be heavier than the second weight 4A. By moving forward, the first weight 3A fits into the inclined portion of the movement space 20A, making it difficult for the first weight 3A to return backward. In other words, the swimming posture after landing can be stabilized.

[0047] The second weight 4A is a spherical weight member that is formed so that it can move in the front-to-rear direction by rolling within the movement space 20A. The second weight 4A is formed of a magnetic material that is attracted by the magnetic force of a magnet. The second weight 4A is disposed behind the first weight 3A in the movement space 20A. The size and weight of the second weight 4A can be set as appropriate, but in this embodiment, the outer diameter of the second weight 4A is larger than the outer diameter of the first weight 3A.

[0048] The elastic member 5A is an elastic member disposed between the first weight 3A and the second weight 4A. The elastic member 5A is a spherical rubber member and is formed so as to be able to move in the front-to-rear direction by rolling within the movement space 20A.

[0049] The magnetic body 6 of this embodiment differs from the first embodiment in that it is placed on the upper part 31. In this way, the second weight 4A may be attracted from outside the movement space 20A. The behavior of the lure 1A is the same as in the first embodiment, so a description thereof will be omitted.

[0050] The lure 1A described above can achieve substantially the same effects as the first embodiment. In this embodiment, the first weight 3A, the second weight 4A, and the elastic member 5A are spherical, so they can move by rolling within the movement space 20A. Therefore, separate components for moving the first weight 3A and the second weight 4A can be omitted, reducing the number of parts.

[0051] Third Embodiment Next, a lure according to a third embodiment will be described. As shown in Fig. 6, the elastic member of the third embodiment is different from that of the first embodiment. The third embodiment will be described focusing on the differences from the first embodiment. The third embodiment aims to provide a lure that can increase the flight distance when cast.

[0052] The lure 1B includes a main body 2, a first weight 3, an elastic member 5B, a magnetic body 6, and a shaft member 7. That is, the lure 1B differs from the first embodiment in that the second weight 4 of the first embodiment is omitted. The elastic member 5B is made of elastic resin or rubber and is disposed behind the first weight 3.

[0053] The elastic member 5B is cylindrical and made of resin or rubber mixed with magnetic powder. In other words, the elastic member 5B can be attracted to the magnetic body 6. This allows the elastic member 5B to function both as an elastic member that pushes the first weight 3 forward and as the second weight 4 in the first embodiment. The size and weight of the elastic member 5B can be set as appropriate. In this embodiment, the weight of the elastic member 5B is lighter than that of the first weight 3, and the outer diameter of the elastic member 5B is larger than that of the first weight 3. The elastic member 5B may be configured in any manner as long as it is magnetizable and has sufficient elasticity to push the first weight 3 forward. For example, the elastic member 5B may be a magnetic body surrounded by elastic resin.

[0054] The lure 1B described above can achieve substantially the same effects as the first embodiment. Furthermore, in this embodiment, the elastic member 5B is attracted to the magnetic body 6, so it can function both as an elastic member and as a second weight. This allows for space saving, so the center of gravity can be appropriately shifted even in lures where the main body 2 is short in the front-to-rear direction. Furthermore, this embodiment allows for a reduction in the number of parts.

[0055] <Fourth embodiment> Next, a lure according to a fourth embodiment will be described. As shown in Fig. 7, the fourth embodiment differs from the first embodiment in that the first weight, the second weight, and the elastic member are spherical. The fourth embodiment will be described focusing on the differences from the first embodiment.

[0056] The lure 1C includes a main body 2, a first weight 3C, a second weight 4C, an elastic member 5C, a magnetic body 6, and a shaft member .

[0057] The first weight 3C is a spherical weight member. The first weight 3C is inserted through the shaft member 7 so as to be movable in the front-rear direction, and is disposed forward of the second weight 4C and the elastic member 5C. The first weight 3C is made of a non-magnetic, high-density metal that is not attracted to a magnet. The size and weight of the first weight 3C can be set as appropriate, but in this embodiment, the first weight 3C is formed to be heavier than the second weight 4C.

[0058] The second weight 4C is a spherical weight member. The second weight 4C is inserted through the shaft member 7 so as to be movable in the front-rear direction, and is disposed rearward of the first weight 3C and the elastic member 5C. The second weight 4C is formed of a magnetic material that is attracted by the magnetic force of a magnet. The size and weight of the second weight 4C can be set as appropriate, but in this embodiment, the outer diameter of the second weight 4C is larger than the outer diameter of the first weight 3C.

[0059] The elastic member 5C is spherical and made of an elastic material. An example of an elastic material is a rubber material. The elastic member 5C is inserted movably in the front-rear direction of the shaft member 7 and is disposed between the first weight 3C and the second weight 4C. The behavior of the lure 1C is the same as in the first embodiment, so a description thereof will be omitted.

[0060] The lure 1C described above can also achieve substantially the same effects as the first embodiment.

[0061] Although the embodiment of the present invention has been described above, appropriate design changes are possible within the scope of the invention. For example, in this embodiment, the posture of the lure 1 is set to the front center of gravity, but the center of gravity may be set in the center. In other words, the center of gravity may be set so that the front-to-back axis of the lure is horizontal. [Explanation of symbols]
