Description

[Technical Field]

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

[0002] The lure described in Patent Document 1 has a body, a shaft, a weight, and an elastic member. The shaft is formed from a straight wire material. The shaft extends linearly in the front-to-rear direction inside the body. The weight is supported by a guide member inside the body so as to be movable in the front-to-rear direction. The elastic member biases the weight forward.

[0003] In this type of lure, when the lure is cast, the weight moves linearly along the shaft toward the tail side due to inertial force while compressing the elastic member. When the lure hits the water, the weight is pushed linearly back along the shaft toward the head side by the biasing force of the elastic member. This movement of the weight ensures that the lure maintains its position when cast and when hit. Furthermore, when the lure is swimming, the weight moves linearly back and forth along the shaft in response to external forces acting on the lure. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-193921 Summary of the Invention [Problem to be solved by the invention]

[0005] In the lure of Patent Document 1, the shaft is formed in a straight line. In this case, the movement path of the weight is limited to a straight line, so depending on the shape and internal structure of the lure, it is difficult to place the weight in an optimal position. In other words, since the degree of freedom of the movement path of the weight is limited to a straight line, it is difficult to place the center of gravity in the position desired by the designer.

[0006] An object of the present invention is to provide a lure whose center of gravity can be suitably set. [Means for solving the problem]

[0007] According to a first aspect of the present invention, a lure includes a body, a support portion, and a weight. The body has a head at the front and a tail at the rear. The support portion extends in the front-to-rear direction inside the body. The support portion is supported by the body so as to be movable in a direction intersecting the front-to-rear direction. The weight is supported by the support portion so as to be movable in the front-to-rear direction.

[0008] In this lure, the support portion is movable in the cross direction, and the weight is supported by the support portion so as to be movable in the front-to-rear direction. Therefore, when the support portion moves in the cross direction, the weight also moves in the cross direction together with the support portion. In this way, this lure can improve the degree of freedom of the weight's movement path compared to conventional techniques. In other words, this lure can suitably set the center of gravity position. Furthermore, since the weight moves not only in the front-to-rear direction but also in the cross direction depending on the action (reeling operation) given to the lure by the angler, the lure can be made to behave more erratically.

[0009] With respect to the second aspect of the present invention, the lure according to the first aspect is configured as follows. The support part is a shaft member formed in a shaft shape. The shaft member is swingable with the tail side as the swing center. In this configuration, by swinging the weight supported by the support part, the degree of freedom of the movement path of the weight can be improved.

[0010] With respect to a third aspect of the present invention, a lure according to the third aspect is configured as follows. The shaft member has a front end portion disposed on the head side and a rear end portion supported by the body on the tail side so as to be swingable. The body has a groove portion that guides the front end portion of the shaft member in the crossing direction. With this configuration, the front end portion of the shaft member is guided in the crossing direction by the groove portion of the body, so that the weight supported by the support portion can be moved stably in the crossing direction.

[0011] With respect to the fourth aspect of the present invention, the lure according to the first aspect further includes a biasing member that biases the weight at least forward. With this configuration, the weight can be easily returned to the head side. [Effects of the Invention]

[0012] According to the present invention, the center of gravity of the lure can be suitably set. [Brief explanation of the drawings]

[Figure 2] FIG. 10 is a side view illustrating the internal structure of the lure when the weight is positioned upward. [Figure 3] FIG. 10 is a side view illustrating the internal structure of the lure when the weight is positioned downward. [Figure 4] FIG. 10 is a side view illustrating a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0014] In this embodiment, the lure according to the present invention will be described using the lure 1 shown in Fig. 1. As shown in Fig. 2, the lure 1 includes a body 3, a support part 5, a weight 7, and a biasing member 11.

[0015] (body) 2 and 3, the body 3 has a main body 13, a first slit portion 17, a support hole 19 (see FIG. 3), and a second slit portion 22. The main body 13 has a head 13a at the front and a tail 13b at the rear.

[0016] 1, the outer shape of the main body 13 is formed in a streamlined shape that is long in one direction from the front to the rear. In the lure 1 in which a fishing line (not shown) is connected to the line eye 21, the direction in which the lure 1 moves as it is pulled by the fishing line is determined as "front" and "forward."

[0017] The direction toward the water surface when the lure 1 is moving forward in the water is determined as "upward." The direction toward the water bottom is determined as "downward." The left-right direction is perpendicular to the front-back direction and the up-down direction. The crossing direction intersects with the front-back direction. In this embodiment, the up-down direction is sometimes used to mean the crossing direction.

[0018] 1, the main body 13 includes a first main body 29 and a second main body 31. The first main body 29 and the second main body 31 are formed by dividing the main body 13 by a plane defined by the front-rear direction and the up-down direction.

[0019] As shown in Figures 2 and 3, the first main body 29 includes a first joint surface 29a. The first joint surface 29a extends in the front-to-rear direction. A first front wall 23a is provided on the inner lateral surface of the first main body 29 on the head 13a side. The first front wall 23a extends in the up-down direction. A first rear wall 25a is provided on the inner lateral surface of the first main body 29 on the tail 13b side. The first rear wall 25a extends in the up-down direction.

[0020] A first positioning wall 27a is provided on the inner lateral surface of the first main body 29 on the tail 13b side. The first positioning wall 27a is provided between the first front wall 23a and the first rear wall 25a in the front-to-rear direction. The first positioning wall 27a extends in the up-and-down direction. A first upper rib 15a is provided on the inner lateral surface of the first main body 29. The first upper rib 15a extends in the front-to-rear direction above the hook eye storage portion 41.

[0021] A first lower rib 16a is provided on the inner surface of the first main body 29. The first lower rib 16a is disposed between the first upper rib 15a and the hook eye storage portion 41 in the up-down direction. The first lower rib 16a extends in the front-to-rear direction above the hook eye storage portion 41.

[0022] 1, the second body 31 is disposed opposite the first body 29. The second body 31 is configured to be a mirror image of the first body 29. In other words, the configuration of the second body 31 is substantially the same as the configuration of the first body 29. For this reason, the configuration of the second body 31 that corresponds to the configuration of the first body 29 is given the symbol b, and the configuration of the second body 31 given the symbol b is written in parentheses in each drawing.

[0023] For example, the second main body 31 has a second front wall 23b, a second rear wall 25b, and a second positioning wall 27b. The first front wall 23a and the second front wall 23b form the front wall 23. The first rear wall 25a and the second rear wall 25b form the rear wall 25. The first positioning wall 27a and the second positioning wall 27b form the positioning portion 27. The first upper rib 15a and the second upper rib 15b form the upper rib 15.

[0024] 2 and 3, by joining the first joining surface 29a of the first body 29 and the joining surface 29b of the second body 31, an internal space is formed between the first body 29 and the second body 31. A first slit portion 17 is formed between the first front wall 23a and the second front wall 23b.

[0025] The first slit portion 17 is provided inside the main body 13 on the head 13a side. The support portion 5 is inserted into the first slit portion 17. The first slit portion 17 guides the front end portion of the support portion 5 in the cross direction. More specifically, the first slit portion 17 guides the front end portion of the support portion 5 in the up-down direction. The swing range of the support portion 5 is determined by the length of the first slit portion 17 in the up-down direction.

[0026] A support hole 19 is formed between the first rear wall 25a and the second rear wall 25b. The rear end of the support part 5 is inserted into the support hole 19. The support hole 19 supports the rear end of the support part 5 so that it can swing. In this embodiment, a swing center C is defined by the position of the support hole 19.

[0027] As shown in FIGS. 2 and 3, a second slit portion 22 is provided between the first positioning wall 27a and the second positioning wall 27b. The second slit portion 22 is provided inside the main body 13 on the tail 13b side. The rear portion of the support portion 5 and the rear portion of the urging member 11 are inserted into the second slit portion 22. The second slit portion 22 guides the rear end portion of the support portion 5 and the rear portion of the urging member 11 in the cross direction. In detail, the second slit portion 22 guides the rear end portion of the support portion 5 and the rear portion of the urging member 11 in the up-and-down direction.

[0028] The positioning portion 27 is provided inside the main body 13 on the tail 13b side. When the first main body 29 and the second main body 31 are joined together, the positioning portion 27 is formed by a first positioning wall 27a of the first main body 29 and a second positioning wall 27b of the second main body 31. When the weight 7 moves rearward, the rear portion of the weight 7 abuts against the positioning portion 27, thereby positioning the weight 7 on the tail 13b side.

[0029] (Support part) As shown in Figures 2 and 3, the support part 5 supports the weight 7. The support part 5 extends in the front-rear direction inside the main body 13. The support part 5 is disposed inside the main body 13. Specifically, the support part 5 is an axial member formed in an axial shape.

[0030] 3 and 4, the support part 5 is supported by the main body 13 so as to be movable in the intersecting direction. In this embodiment, the support part 5 is supported by the main body 13 so that the tail side part of the support part 5 becomes the swing center C when the support part 5 supports the weight body 7.

[0031] Specifically, the front end of the support part 5 is inserted into the first slit part 17. The rear part of the support part 5 is inserted into the second slit part 22. The rear end of the support part 5 is inserted into the support hole 19 and engaged with either the first rear wall 25a or the second rear wall 25b.

[0032] The front end and rear end of the support part 5 move up and down separately within the first slit part 17 and the second slit part 22 depending on the position of the weight 7. The rear end part of the support part 5 is supported by the support hole 19 so as to be able to swing, with position C of the support hole 19 as the swing center. In this way, the support part 5 swings around the swing center C, which is the rear end part of the support part 5.

[0033] (pyramid) 2 and 3, weight 7 is supported by support part 5 inside main body 13. As shown in Fig. 3, weight 7 is supported by support part 5 so as to be movable in the front-rear direction.

[0034] The weight 7 has a weight main body 7a and a hole 7b. The hole 7b is provided in the weight main body 7a. The hole 7b penetrates the weight main body 7a in the front-rear direction. The support part 5 is inserted into the hole 7b. With this configuration, the weight main body 7a moves in the front-rear direction along the support part 5, as shown in FIG. 2.

[0035] The weight 7 moves in the front-to-rear direction between a first position on the head 13a side (position indicated by a solid line in FIG. 2) and a second position on the tail 13b side (position indicated by a two-dot dashed line in FIG. 2). The first position on the head 13a side is a position where the front part of the weight 7 is closest to the front wall 23. In this embodiment, the first position on the head 13a side is a position where the front part of the weight 7 abuts against the front wall 23.

[0036] The second position on the tail 13b side is a position where the rear part of the weight 7 is closest to the positioning portion 27. In this embodiment, the second position on the tail 13b side is a position where the rear part of the weight 7 abuts against the positioning portion 27.

[0037] 2 and 3, weight 7 is supported by support part 5 so as to be movable in the up and down direction. In particular, when support part 5 swings around swing center C, weight 7 moves in the up and down direction while being supported by support part 5. In this state, weight 7 moves in the front and back direction along support part 5.

[0038] (biasing member) The biasing member 11 biases the weight 7 at least in the forward direction. In this embodiment, as shown in FIGS. 2 and 3, the biasing member 11 is a coil spring. The biasing member 11 is disposed between the weight 7 and the rear wall 25. When the weight 7 is disposed in the first position on the head 13a side, the biasing member 11 is compressed.

[0039] In the lure 1 having the above configuration, as shown in Fig. 2, the weight 7 is supported by the support part 5 and moves in the front-to-back direction along the support part 5 between the front and rear parts of the body 3. In detail, the weight 7 moves in the front-to-back direction along the support part 5 between a first position on the head 13a side (position indicated by a solid line in Fig. 2) and a second position on the tail 13b side (position indicated by a two-dot dashed line in Fig. 2).

[0040] Here, when a downward force acts on the weight 7 while the weight 7 is positioned at the first position on the head 13a side, as shown by the solid line in Figure 2, the support part 5 swings downward, and the weight 7 moves downward, as shown in Figure 3.

[0041] 3 at the first position on the head 13a side, the weight 7 moves in the front-to-rear direction along the support part 5. When an upward force acts on the weight 7 in this state, the support part 5 swings upward, causing the weight 7 to move upward. As a result, the weight 7 returns to the position shown by the solid line in FIG. 2 at the first position on the head 13a side.

[0042] When weight 7 is positioned between a first position on head 13a and a second position on tail 13b in the front-to-rear direction, if an upward or downward force acts on weight 7, support part 5 swings upward or downward. That is, weight 7 moves upward or downward between the first position on head 13a and the second position on tail 13b.

[0043] In the lure 1, the support part 5 is movable in the cross direction, and the weight 7 is supported by the support part 5 so as to be movable in the front-to-rear direction. Therefore, when the support part 5 moves in the cross direction, the weight 7 also moves in the cross direction together with the support part 5. In this way, in the lure 1, the degree of freedom of the movement path of the weight 7 can be improved compared to the prior art. That is, in the lure 1, the center of gravity position can be suitably set. Furthermore, since the weight 7 moves not only in the front-to-rear direction but also in the cross direction depending on the action (reeling operation) given to the lure 1 by the angler, the lure 1 can be made to behave more erratically.

[0044] In this fishing lure 1, the weight 7 supported by the support portion 5 is swung, thereby improving the degree of freedom of the movement path of the weight 7. In this fishing lure 1, the front end of the shaft-shaped support portion 5 is guided in the crossing direction by the first slit portion 17 of the body 3, so the weight 7 supported by the support portion 5 can be moved stably in the crossing direction. In this fishing lure 1, the weight 7 can be easily returned to the head 13a side.

[0045] <Modification> Although one embodiment of the present invention has been described above, the present invention is not limited to the first embodiment, and various modifications are possible without departing from the gist of the invention.

[0046] In the configuration of the above embodiment, the lure 1 may further include a magnet 10 as shown in FIG. 4. In this case, at least a portion of the weight 7 is made of a magnetic material. In this embodiment, the weight 7 is made of a magnetic material. As a result, the weight 7 is attracted by the magnet 10.

[0047] The magnet 10 is provided on the main body 13 so as to hold the weight 7 at a first position on the head 13a side. In this embodiment, the magnet 10 is provided on the upper rib 15. In this configuration, when the weight 7 is positioned at the first position on the head 13a side, as shown by the solid line in FIG. 4, the weight 7 is held by the magnet 10. In this state, when the force acting backward on the weight 7 becomes greater than the force with which the magnet 10 attracts the weight 7, the weight 7 moves backward along the support part 5.

[0048] When the weight 7 is positioned at the first position on the head 13a side, as shown by the solid line in Figure 4, and the downward force acting on the weight 7 becomes greater than the force with which the magnet 10 attracts the weight 7, the support part 5 swings downward and the weight 7 moves downward.
