Description

[Technical Field]

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

[0002] Conventionally, lures have been known in which the center of gravity is shifted by moving a spherical weight during casting and after landing on the water (see Patent Document 1). The weight is disposed inside the body of the lure so as to be movable in the front-to-rear direction of the lure. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 2844045 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, in structures that move the center of gravity of a lure by moving a spherical weight, the number of weights is around one to three, and there is a problem that as the spherical diameter of the weight increases, the center of gravity of the lure becomes higher.

[0005] An object of the present invention is to provide a lure that can prevent the position of the center of gravity of the lure from becoming high in water. [Means for solving the problem]

[0006] A lure according to a first aspect of the present invention comprises a body, a first storage section, a second storage section, a connecting passage, and a plurality of sinkers. The body extends in the front-to-rear direction. The first storage section is disposed inside the body. The second storage section is disposed inside the body forward of the first storage section. The connecting passage connects the first storage section and the second storage section. The plurality of sinkers are movable from the first storage section to the second storage section via the connecting passage. The plurality of sinkers include a first sinker and a second sinker. When the plurality of sinkers are stored in the second storage section, the second sinker overlaps the first sinker when viewed from the left-to-right direction.

[0007] In this lure, when the multiple sinkers are stored in the second storage section, the first sinker and the second sinker overlap each other when viewed from the left and right. This allows the spherical diameter of the multiple sinkers to be reduced, thereby increasing the total number of multiple sinkers stored in the second storage section. This allows the lure's center of gravity to be lower than conventional lures when the multiple sinkers are stored in the second storage section, even if the total weight of the multiple sinkers is the same as conventional lures. As a result, the lure's center of gravity can be prevented from becoming too high in water. Furthermore, since the lure's center of gravity can be prevented from becoming too high, the roll axis of the lure's swimming vibration can be kept low. This is expected to result in a greater rolling motion of the lure when reeling in the fishing line.

[0008] The second storage compartment of the lure according to the first aspect of the present invention can store a plurality of sinkers in parallel. In this case, the total number of sinkers stored in the second storage compartment can be further increased. Alternatively, the size of the second storage compartment in the front-to-rear direction can be reduced.

[0009] The lure of a third aspect according to the first or second aspect of the present invention further comprises a lubricant for suppressing friction between the plurality of sinkers and the connecting passage, in which case the movement of the plurality of sinkers in the connecting passage becomes smooth.

[0010] According to any one of the first to third aspects of the present invention, a lure connecting passage of a fourth aspect includes a guide portion disposed adjacent to the first storage portion and guiding movement of the plurality of sinkers, the guide portion including an upper surface portion inclined downward toward the front, in this case, the movement of the plurality of sinkers becomes smooth when the plurality of sinkers move from the first storage portion to the second storage portion.

[0011] The lure guide portion of a fifth aspect according to any one of the first to fourth aspects of the present invention further includes a lower surface portion disposed below the upper surface portion and inclined upward toward the front. In this case, it is possible to prevent the plurality of sinkers from moving from the first storage portion to the second storage portion against the angler's intention.

[0012] In a sixth aspect according to any one of the first to fifth aspects of the present invention, the lure connecting passage is disposed adjacent to the second storage section and includes an upright section that guides the sinkers upward. In this case, the sinkers can be prevented from moving from the second storage section to the first storage section against the angler's intention.

[0013] The second lure storage section of a seventh aspect according to any one of the first to sixth aspects of the present invention includes a ceiling portion that restricts upward movement of the plurality of sinkers. In this case, for example, the ceiling portion can prevent the lure's center of gravity from becoming higher in water. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a lure that can prevent the center of gravity from becoming high in water. [Brief explanation of the drawings]

[0015] [Figure 1] Left side view of the lure. [Figure 2] A longitudinal cross section of the lure. [Figure 3] Horizontal cross section of the lure. [Figure 4] Cross section of the lure [Figure 5] FIG. 10 is a diagram illustrating a state in which a plurality of weights are stored in a first storage section. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a lure according to an embodiment will be described with reference to the drawings. Fig. 1 is a left side view of the lure 1. As shown in Fig. 1, the lure 1 includes a body 2, a line eye 3, front hook eyes 4 and 5, and a rear hook eye 6.

[0017] In this specification, terms indicating directions such as "front," "rear," "left," "right," "up," and "down" refer to directions determined in the lure 1 such that the direction in which the lure 1 is pulled by the fishing line is "front," the direction toward the water surface when the lure 1 is moving forward in the water is "up," and the direction toward the bottom of the water is "down." For example, in FIG. 1, the left side of FIG. 1 is "front," the right side of FIG. 1 is "rear," the upper side of FIG. 1 is "up," the lower side of FIG. 1 is "down," the front side of the page in FIG. 1 is "left," and the back side of the page in FIG. 1 is "right."

[0018] Fig. 2 is a cross-sectional view of the lure 1 taken along a plane perpendicular to the left-right direction. Fig. 3 is a cross-sectional view of the lure 1 taken along a plane perpendicular to the up-down direction. Fig. 4 is a cross-sectional view of the lure 1 taken along a plane perpendicular to the front-rear direction.

[0019] The body 2 extends in the front-rear direction. The body 2 is hollow and has an internal space. The body 2 is made of resin and is formed by joining two separate parts, left and right, together.

[0020] The body 2 includes a head 7, a butt 8, and a lip 9. The head 7 is located on the front side of the body 2. The butt 8 is located on the rear side of the body 2. The lip 9 is connected to the head 7. The lip 9 protrudes forward beyond the head 7. In a side view, the lip 9 extends forward and downward from the bottom of the head 7. When the lure 1 is pulled by the fishing line and moves forward through the water, the lip 9 receives resistance from the water, causing the lure 1 to assume a forward-leaning posture.

[0021] The line eye 3, the front hook eyes 4 and 5, and the rear hook eye 6 are formed by bending a single metal wire. The line eye 3, the front hook eyes 4 and 5, and the rear hook eye 6 are exposed from the body 2. A fishing line (not shown) is tied to the line eye 3. A hook (not shown) is attached to each of the front hook eyes 4 and 5 and the rear hook eye 6.

[0022] The lure 1 includes a first storage section 11, a second storage section 12, a connecting passage 13, and a plurality of sinkers 14.

[0023] The first storage section 11 is capable of storing a plurality of weights 14. The first storage section 11 is disposed inside the body 2. The first storage section 11 is disposed inside the buttocks section 8. The first storage section 11 extends in the front-to-rear direction. The first storage section 11 is formed so that the dimension in the up-down direction increases toward the front.

[0024] The first storage section 11 includes an upper surface 11a and a lower surface 11b. The upper surface 11a is inclined upward toward the front. The lower surface 11b is disposed below the upper surface 11a. The lower surface 11b is inclined downward toward the front.

[0025] The second storage section 12 can store multiple weights 14 in parallel. The second storage section 12 is arranged inside the body 2. The second storage section 12 is arranged forward of the first storage section 11. The second storage section 12 is arranged inside the head 7. The second storage section 12 is arranged above the front hook eye 4. The second storage section 12 extends in the front-to-rear direction. The dimension of the second storage section 12 in the up-down direction is smaller than the dimension of the first storage section 11 in the up-down direction. The front end of the second storage section 12 is formed so that the dimension in the left-to-right direction decreases toward the front.

[0026] The second storage section 12 includes a ceiling section 12a and a bottom section 12b. The ceiling section 12a restricts the upward movement of the multiple weights 14. The ceiling section 12a extends in a direction approximately perpendicular to the up-down direction. The ceiling section 12a is disposed lower than the upper surface section 11a of the first storage section 11. The bottom section 12b is disposed below the ceiling section 12a. The bottom section 12b extends in a direction approximately perpendicular to the up-down direction. The bottom section 12b is approximately parallel to the ceiling section 12a.

[0027] The connecting passage 13 is disposed inside the body 2 between the first storage section 11 and the second storage section 12. The connecting passage 13 connects the first storage section 11 and the second storage section 12. The connecting passage 13 extends in the front-rear direction. The connecting passage 13 is disposed above the front hook eye 5.

[0028] The connecting passage 13 includes a guide portion 21, an upright portion 22, and an intermediate portion 23. The guide portion 21 is disposed adjacent to the first storage portion 11. The guide portion 21 extends in the front-to-rear direction. The guide portion 21 guides the movement of the multiple weights 14. The guide portion 21 guides the movement of the multiple weights 14 in the front-to-rear direction. The guide portion 21 is formed so that its vertical dimension decreases toward the front. The guide portion 21 is disposed above the front hook eye 5.

[0029] The guide portion 21 includes an upper surface portion 21a and a lower surface portion 21b. The upper surface portion 21a is connected to the upper surface portion 11a of the first storage portion 11. The upper surface portion 21a is inclined downward toward the front. The lower surface portion 21b is disposed below the upper surface portion 21a. The lower surface portion 21b is connected to the lower surface portion 11b of the first storage portion 11. The lower surface portion 21b is inclined upward toward the front.

[0030] The standing portion 22 is disposed adjacent to the second storage portion 12. The standing portion 22 extends in the vertical direction. The standing portion 22 guides the plurality of weights 14 upward. In detail, the standing portion 22 guides the plurality of weights 14 upward when the plurality of weights 14 move from the second storage portion 12 to the first storage portion 11.

[0031] The standing portion 22 includes a front portion 22a and a rear portion 22b. The front portion 22a is connected to the ceiling portion 12a. The front portion 22a is inclined upward and rearward from the rear end of the ceiling portion 12a. The rear portion 22b is located rearward of the front portion 22a. The rear portion 22b is connected to the bottom portion 12b. The rear portion 22b includes a first portion extending upward from the rear end of the bottom portion 12b and a second portion inclined upward and rearward from the first portion.

[0032] The intermediate portion 23 is disposed between the guide portion 21 and the standing portion 22. The intermediate portion 23 is connected to the guide portion 21 and the standing portion 22. The intermediate portion 23 extends in the front-rear direction. The intermediate portion 23 is inclined upward toward the front.

[0033] The plurality of sinkers 14 can be moved from the first storage section 11 to the second storage section 12 via the connecting passage 13. The plurality of sinkers 14 can be moved from the second storage section 12 to the first storage section 11 via the connecting passage 13. The plurality of sinkers 14 are spherical. The spherical diameter of the plurality of sinkers 14 is set, for example, according to the shape of the lure.

[0034] Fig. 5 is a diagram illustrating a state in which a plurality of sinkers 14 are stored in the first storage section 11. As shown in Fig. 5, during casting, the plurality of sinkers 14 are stored in the first storage section 11 by centrifugal force. When the plurality of sinkers 14 are stored in the first storage section 11, at least some of the plurality of sinkers 14 overlap with each other when viewed from the left-right direction. When the plurality of sinkers 14 are stored in the first storage section 11, at least some of the plurality of sinkers 14 overlap with each other when viewed from the top-bottom direction.

[0035] After being cast, when the lure 1 is pulled by the fishing line and moves forward in the water, the lip 9 receives resistance from the water, causing the lure 1 to assume a forward tilting posture, and the multiple sinkers 14 move from the first storage section 11 to the second storage section 12 via the connecting passage 13.

[0036] When the multiple weights 14 are stored in the second storage section 12, at least some of the multiple weights 14 overlap when viewed from the left and right. When the multiple weights 14 are stored in the second storage section 12, the multiple weights 14 do not overlap when viewed from the top and bottom. When the multiple weights 14 are stored in the second storage section 12, each of the multiple weights 14 can come into contact with the bottom surface portion 12b.

[0037] In this embodiment, the plurality of weights 14 includes 11 weights in total. The plurality of weights 14 includes a first weight 14a and a second weight 14b. The second weight 14b is adjacent to the first weight 14a in the left-right direction. When the plurality of weights 14 are stored in the second storage section 12, the second weight 14b overlaps with the first weight 14a when viewed from the left-right direction. When the plurality of weights 14 are stored in the second storage section 12, the second weight 14b is aligned with the first weight 14a in the left-right direction. As shown in FIGS. 2 and 3 , when the plurality of weights 14 are stored in the second storage section 12, the plurality of weights 14 are aligned linearly in two rows in the front-to-back direction, except for the third weight 14c located at the front. When the plurality of weights 14 are stored in the second storage section 12, the third weight 14c overlaps with the first weight 14a and the second weight 14b when viewed from the left-to-right direction.

[0038] At least some of the plurality of sinkers 14 stored in the first storage section 11 are located higher than the plurality of sinkers 14 stored in the second storage section 12. The center of gravity of the lure when the plurality of sinkers 14 are stored in the second storage section 12 is located lower than the center of gravity of the lure when the plurality of sinkers 14 are stored in the first storage section 11. In other words, as the plurality of sinkers 14 move from the first storage section 11 to the second storage section 12, the center of gravity of the lure 1 moves downward.

[0039] In the lure 1 configured as described above, when the plurality of sinkers 14 are stored in the second storage section 12, the first sinker 14a and the second sinker 14b overlap each other when viewed from the left and right. This allows the spherical diameter of the plurality of sinkers 14 to be reduced, thereby increasing the total number of the plurality of sinkers 14 stored in the second storage section 12. This allows the center of gravity of the lure 1 to be lower than conventionally when the plurality of sinkers 14 are stored in the second storage section 12, even if the total weight of the plurality of sinkers 14 is the same as conventionally. As a result, the center of gravity of the lure 1 can be prevented from becoming higher in water. Furthermore, since the center of gravity of the lure 1 can be prevented from becoming higher, the roll axis of the swimming vibration of the lure 1 can also be kept lower. This is expected to result in a greater rolling motion of the lure 1 when reeling in the fishing line.

[0040] <Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0041] The lure 1 may further include a lubricant to reduce friction between the plurality of sinkers 14 and the connecting passage 13. The lubricant may be, for example, silicone oil, and may be sealed inside the body 2.

[0042] The total number of the plurality of weights 14 may be changed. The total number of the plurality of weights 14 may be changed, for example, according to the size of the spherical diameter of the plurality of weights 14. The plurality of weights 14 may be arranged in a staggered pattern in the second storage section 12. [Explanation of symbols]
