Description

Technical Field

[0001] The present invention relates to lures.

Background Art

[0002] As materials for lures used in fishing, wood, metal, resin, etc. are used. Wood lacks mass productivity and quality stability, and it is difficult to adjust the weight and buoyancy of metal with respect to the size. Therefore, resin is generally used as a material for lures. In particular, ABS resin is widely used as a material for lures because it is excellent in terms of strength, impact resistance, and moldability.

[0003] For example, Patent Document 1 discloses a pseudo-bait (lure) characterized in that the main body is made of a soft resin and has a hollow portion inside the main body. According to Patent Document 1, the pseudo-bait can have flexibility and elasticity like a real fish while having buoyancy.

Summary of the Invention

Problems to be Solved by the Invention

[0005] General ABS resin used as a material for lures has a large flexural modulus of 1800 MPa or more and low flexibility. A lure formed of such an ABS resin with a flexural modulus of 1800 MPa or more may have an unnatural behavior when prey such as fish or squid hits it, or when a sudden change in movement is applied to the lure. Once the hit prey bounces off the lure and leaves it, or the lure itself makes unrealistic movements, the attractiveness to the prey may decrease.

[0006] On the other hand, when an action is applied to a lure formed of a soft resin as described in Patent Document 1 through a line, the lure may be greatly deformed and its behavior may become unnatural. A lure that exhibits unnatural behavior due to deformation may also have low attractiveness to prey.

[0007] An object of the present invention is to provide a lure that exhibits more natural behavior when prey such as fish or squid hits it or when a sudden change in movement is applied through a line.

Means for Solving the Problems

[0008] A lure according to one aspect of the present invention includes a body. The body includes a resin having a flexural modulus of 500 MPa or more and 1750 MPa or less. The body has a hollow portion inside.

[0009] The resin can have a Charpy impact strength of 10 KJ / m 2 or more.

[0010] The lure can further include a line connection member for connecting a line. In this case, the body can include an outer shell portion that extends along the outer edge of the hollow portion and a line connection member installation portion. The line connection member installation portion can be connected to the outer shell portion. A line connection member may be installed in the line connection member installation portion. The outer shell portion of the body can have a wall thickness of 0.5 mm or more and 3.5 mm or less.

[0011] The body can include a first half body and a second half body. The second half body can be joined to the first half body. The lure can further include a line connection member for connecting a line, which is installed between the first half body and the second half body of the body.

Effects of the Invention

[0012] A lure according to one aspect of the present invention can exhibit more natural behavior when prey such as fish or squid hits it or when a sudden change in movement is applied through a line.

Modes for Carrying Out the Invention

[0014] <1. Resin> Hereinafter, embodiments of the resin used for a lure according to one aspect of the present invention will be described.

[0015] A lure according to one aspect of the present invention includes a body. The body includes a resin having a flexural modulus of 500 MPa or more and 1750 MPa or less. The body further has a hollow portion. Here, the body "including" the resin means that the body includes the resin as a main material. The body preferably contains the resin at a ratio of 80% by weight or more, more preferably 90% by weight or more, still more preferably 95% by weight or more, particularly preferably 98% by weight or more, and most preferably consists of the resin.

[0016] In this specification, the flexural modulus of the resin refers to a value measured by the method specified in ISO178:2010 (JIS K 7171:2016) at 23°C. As a specific example of the measurement conditions, the measurement conditions described in the examples can be mentioned.

[0017] Since the flexural modulus of the resin is 1750 MPa or less, the body having the hollow portion has flexibility. Therefore, the lure according to one aspect of the present invention can exhibit natural behavior when the prey hits or when a sudden change in movement is applied through the line. For example, according to the lure according to one aspect of the present invention, it is less likely that the hit prey will bounce off the lure. In addition, the lure according to one aspect of the present invention can produce a natural movement similar to that of a living organism when a change in movement is applied through the line, and has a high attractiveness to prey.

[0018] On the other hand, since the flexural modulus of the resin is 500 MPa or more, excessive deformation of the body having the hollow portion is suppressed. Therefore, the lure according to one aspect of the present invention does not deform excessively when an action is applied through the line, and can produce a natural movement similar to that of a living organism. From this perspective as well, the fishing result is likely to be improved by the lure according to one aspect of the present invention.

[0019] The flexural modulus of the resin is preferably 500 MPa or more and 1500 MPa or less, more preferably 600 MPa or more and 1200 MPa or less, and particularly preferably 650 MPa or more and 1100 MPa or less. In these ranges, the above effects are particularly likely to be achieved.

[0020] In a more preferred embodiment, the resin has a Charpy impact strength of 10 KJ / m 2 or more. In this specification, the Charpy impact strength of the resin refers to the value measured by the method specified in ISO179-1:2010 (JIS K 7111-1:2012) (with notch) at 23°C. As a specific example of the measurement conditions, the measurement conditions described in the examples can be mentioned. Since the Charpy impact strength of the resin is 10 KJ / m 2 or more, it is preferable because the body does not easily break even when the body collides with an obstacle during casting of the lure.

[0021] The Charpy impact strength of the resin is more preferably 12 KJ / m 2The above is the case. In this case, the above effects are particularly likely to be exhibited. The range including the upper limit of the Charpy impact strength of the resin is not particularly limited. For example, it can be 10 KJ / m 2 or more and 100 KJ / m 2 or less, preferably 15 KJ / m 2 or more and 80 KJ / m 2 or less.

[0022] Specific examples of the resin having the above flexural modulus or the resin having the above flexural modulus and the above Charpy impact strength are not particularly limited. In this specification, the resin is a composition containing one or more polymer compounds and is also called a resin composition. The resin may be a composition consisting only of the one or more polymer compounds, but may further contain one or more other components such as a plasticizer and a filler as necessary. The resin can be prepared by appropriately adjusting the type or composition of the one or more polymer compounds contained as components and / or the type or composition of the one or more other components so that the flexural modulus or the flexural modulus and the Charpy impact strength are within a predetermined range. The one or more polymer compounds may be a homopolymer compound, a copolymer compound, or a mixture of a homopolymer compound and a copolymer compound. The one or more polymer compounds may include a crosslinked polymer compound. The resin can also be prepared by appropriately blending two or more resins. For example, an ABS resin in which a plasticizer (for example, a non-functional type acrylic polymer or a low molecular weight body of a non-functional type acrylic polymer (for example, a non-functional type acrylic polymer having a weight average molecular weight (Mw) of 1000 to 7000 in terms of polystyrene)) is blended and adjusted so that the flexural modulus or the flexural modulus and the Charpy impact strength are within a predetermined range is an example of the resin. The resin is not limited to the ABS resin and may be other resins such as a polycarbonate resin. Further, the resin may be a resin without a plasticizer as long as it has desired physical property values.

[0023] <2. Lure> Next, with reference to the drawings, the lure according to the first embodiment will be described. FIG. 1 is a side view of the lure 1 according to the first embodiment. FIG. 2 is a top view of the lure 1 according to the first embodiment. FIG. 3 is an end view taken along line I-I of FIG. 2.

[0024] As shown in FIGS. 1 to 3, the lure 1 according to the first embodiment includes a body 20. The lure 1 further includes a line connection member 30 for connecting a line. The lure 1 further includes a hook 40.

[0025] In this specification, the terms "front", "rear", "frontward", "rearward", "left", "right", "side", "upward", and "downward" indicating the following directions, and any other similar direction-indicating terms are determined as "front" and "frontward" in the lure 1 to which the line is connected as the direction in which the lure 1 is pulled by the line and advances, and the direction toward the water surface when the lure 1 advances forward in the water is "upward", and the direction toward the bottom surface of the water is "downward".

[0026] The body 20 includes a hollow portion 24 inside. The hollow portion 24 extends in the front-rear direction. The body 20 includes an outer shell portion 21 that spreads along the outer edge of the hollow portion 24. The outer shell portion 21 extends in the front-rear direction and extends around the axis in the front-rear direction of the hollow portion 24. The body 20 is connected to the outer shell portion 21 and includes a line connection member installation portion 22 where the line connection member 30 is installed. The line connection member installation portion 22 is connected to the front end of the outer shell portion 21. The line connection member installation portion 22 corresponds to the head portion of the body 20. The body 20 further includes a tail portion 23 that is connected to the outer shell portion 21 and where the hook 40 is installed. The tail portion 23 is connected to the rear end of the outer shell portion 21.

[0027] The body 20 contains resin, preferably containing resin at a ratio of 80% by weight or more, more preferably 90% by weight or more, still more preferably 95% by weight or more, particularly preferably 98% by weight or more, and most preferably consisting of resin. Here, the resin is the resin described in the above <1. Resin>. In particular, among the body 20, the outer shell portion 21 and the line connection member installation portion 22 (more preferably the outer shell portion 21, the line connection member installation portion 22, and the tail portion 23) can each contain the resin in the above manner. The lure 1 can exhibit natural behavior when the prey hits or when a sudden change in movement is applied through the line. Therefore, the effect of enhancing the fishing result can be obtained by the lure 1.

[0028] As shown in FIGS. 2 and 3, the body 20 includes a first half body 25 and a second half body 26. The body 20 is divided into a first half body 25 and a second half body 26 on the left and right. The first half body 25 and the second half body 26 each contain resin, preferably containing resin at a ratio of 80% by weight or more, more preferably 90% by weight or more, still more preferably 95% by weight or more, particularly preferably 98% by weight or more, and most preferably consisting of resin. Here, the resin is the resin described in the above <1. Resin>. In particular, among the first half body 25 and the second half body 26, the portions corresponding to the outer shell portion 21 and the line connection member installation portion 22 (more preferably the portions corresponding to the outer shell portion 21, the line connection member installation portion 22, and the tail portion 23) can each contain the resin in the above manner. The first half body 25 and the second half body 26 are separate from each other and are joined to each other by welding. For example, the first half body 25 and the second half body 26 are joined to each other by ultrasonic welding.

[0029] The first half body 25 includes an inner peripheral surface 25A and a joining surface 25B. The second half body 26 includes an inner peripheral surface 26A and a joining surface 26B. The first half body 25 and the second half body 26 are joined to each other at the joining surfaces 25B and 26B. The joining surfaces 25B and 26B extend in the front-rear direction. The inner peripheral surface 25A of the first half body 25 and the inner peripheral surface 26A of the second half body 26 face each other. The inner peripheral surface 25A of the first half body 25 and the inner peripheral surface 26A of the second half body 26 define the outer edge surrounding the axis in the front-rear direction of the hollow portion 24.

[0030] The outer shell portion 21 of the body 20 has a wall thickness T. As shown in FIG. 3, the wall thickness T is the wall thickness of the portion of the outer shell portion 21 that extends in the front-rear direction and extends around the axis in the front-rear direction of the hollow portion 24. The wall thickness T can be referred to as the "reference wall thickness". The wall thickness T can be in the range of 0.5 mm or more and 3.5 mm or less. The outer shell portion 21 of the body 20 may include portions having a wall thickness other than the wall thickness T within the above range. The outer shell portion 21 having a wall thickness T of 0.5 mm or more and 3.5 mm or less has flexibility and particularly high effects of suppressing excessive deformation. Therefore, the lure 1 including the body 20 having the outer shell portion 21 having a wall thickness T of 0.5 mm or more and 3.5 mm or less is preferable because it has particularly high effects of enhancing the above-described fishing results.

[0031] FIG. 4 is a perspective view of the first half body 25 and the line connection member 30. The line connection member 30 includes a line locking portion 31, a connecting portion 32, and a mounting portion 33. The line locking portion 31 is formed in an annular shape having a through hole for inserting and connecting a line. The mounting portion 33 is formed in an annular shape having a through hole. The connecting portion 32 connects and integrates the line locking portion 31 and the mounting portion 33. The line connection member 30 can be made of metal, and for example, can be formed by processing a metal wire. The line connection member 30 is installed in the line connection member installation portion 22 of the body 20. The line connection member installation portion 22 is composed of a part of the first half body 25 and a part of the second half body 26. The line connection member 30 is installed while being sandwiched between the first half body 25 and the second half body 26. The line connection member installation portion 22 of the body 20 includes a recess 120 for accommodating and fixing the connecting portion 32 and the mounting portion 33 of the line connection member 30. The recess 120 is configured by integrating a first recess 120A formed in the first half body 25 and a second recess 120B formed in the second half body 26. The first half body 25 further includes a protrusion 121 that protrudes from a part of the inner surface of the first recess 120A into the second recess 120B. When the protrusion 121 is inserted into the through hole of the mounting portion 33 of the line connection member 30 within the recess 120, the line connection member 30 is fixed to the line connection member installation portion 22 of the body 20.

[0032] As shown in FIG. 2, the body 20 further includes a plurality of reinforcing plates 27 disposed in the hollow portion 24 so as to intersect the front-rear direction. Each of the plurality of reinforcing plates 27 is disposed on the inner peripheral surface 25A of the first half body 25 and includes a portion protruding toward the second half body 26 (see FIG. 4) and a portion disposed on the inner peripheral surface 26A of the second half body 26 and protruding toward the first half body 25.
