[Technical Field]

[0001] FIELD OF THE INVENTION An embodiment of the present invention relates to a lure. [Background technology]

[0002] Fishing (lure fishing) is practiced using lures made from various materials (wood, plastic, metal, etc.).

[0003] Patent Document 1 discloses a lure consisting of a front section, a middle section, and a rear section, with a first propeller fixed to the tip of the front section and a second propeller fixed to the rear end of the rear section. When the first propeller and the front section rotate due to water current from the front side, the second propeller and the rear section rotate in the opposite direction to the rotation of the first propeller.

[0004] Patent Document 2 discloses a helical lure having two helical members in the longitudinal direction of a core material, the two helical members rotating in different directions. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-087533 [Patent Document 2] Utility Model Registration No. 3196595 Summary of the Invention [Problem to be solved by the invention]

[0006] The front and rear of the lure rotate in different directions, which creates a loud splashing sound and irregularly reflected light, and is expected to attract fish to some extent. However, the movement of the lure itself, which swings from side to side (called "wobbling"), is not very large, so the effect of attracting fish is limited.

[0007] The present invention was completed through extensive research focusing on these issues, and its purpose is to provide a lure that allows the lure body to swing back and forth more easily, making it easier to attract fish. [Means for solving the problem]

[0008] In order to solve the above problems, a first invention is a lure comprising a first twisted portion that twists in a predetermined direction, a second twisted portion that twists in a direction opposite to the predetermined direction, and a fixing portion that fixes the first twisted portion and the second twisted portion so that the rotation directions of the first twisted portion and the second twisted portion are the same.

[0009] A second invention is the lure according to the first invention, wherein the fixing portion is formed integrally with the first twisted portion and the second twisted portion.

[0010] A third invention is the lure according to the first invention, wherein the fixing portion connects the first twisted portion and the second twisted portion in series.

[0011] A fourth invention is the lure according to the first invention, wherein the degree of torsion of the first twisted portion is stronger than the degree of torsion of the second twisted portion.

[0012] A fifth invention is the lure according to the first invention, wherein at least one of the first twisted portion and the second twisted portion is an eccentric rotor.

[0013] A sixth invention is the lure according to the fifth invention, wherein the eccentric rotor has a shape twisted by one rotation at a first pitch and a shape twisted by one rotation at a second pitch.

[0014] A seventh invention is the lure according to the sixth invention, wherein the first pitch and the second pitch have different lengths.

[0015] An eighth invention is the lure according to the sixth invention, wherein the second pitch and the second pitch have the same length. [Effects of the Invention]

[0016] According to the present invention, it is possible to provide a lure that allows the lure body to swing more widely from side to side, making it easier to attract fish. [Brief explanation of the drawings]

[0018] An embodiment of the present invention will be described with reference to the drawings. Common parts in each drawing are designated by the same reference numerals, and duplicated explanations will be omitted. The axis extending from the tip of the lure to the rear end is called the Z axis, the axis extending to the right as viewed from the tip is called the Y axis, and the axis extending upward as viewed from the tip is called the X axis. The Z axis direction is the direction in which water flows.

[0019] (First embodiment) Fig. 1 is a perspective view of a lure according to a first embodiment of the present invention, in which the lure 100 is seen from diagonally above right.

[0020] The lure 100 comprises a front section 110, a rear section 120, and a fixing section 130 that fixes the front section 110 and the rear section 120 together. The front section 110 has a front connection section 111 at its tip. The front connection section 111 has a hole through which a fishing line (not shown) can be passed to directly connect the lure 100 to the fishing line. Alternatively, a ring (not shown) can be separately attached to the hole in the front connection section 111, and the fishing line can be passed through the ring to indirectly connect the lure 100 to the fishing line.

[0021] First twisted portions 112, 113, and 114 having a triple helix shape are formed on the outer periphery of the front portion 110. The first twisted portions can be provided by cutting the outer periphery to form three arc-shaped grooves 112, 113, and 114. The three arc-shaped grooves 112, 113, and 114 have a twisted shape, formed by cutting a clockwise spiral groove from the front to the rear of the front portion 110. Here, clockwise refers to the direction of rotation around the Z axis from the X axis to the Y axis.

[0022] The rear portion 120 has a rear connection portion 121 at its rear end. A hole is provided in the rear connection portion 121, and the ring portion of a fishhook (not shown) can be passed through the hole to directly connect the lure 100 to the fishhook. Alternatively, another ring (not shown) may be separately attached to the hole in the rear connection portion 121, and the ring portion of the fishhook may be passed through the other ring to indirectly connect the lure 100 to the fishhook.

[0023] The outer periphery of the rear portion 120 is formed with second twisted portions 122, 123 in a double helix shape. The second twisted portions can be provided by cutting the outer periphery to form a blade shape with two twisted surfaces 122, 123. The two twisted surfaces 122, 123 are formed by cutting the blade so that they trace a gentle counterclockwise arc from the front to the rear of the rear portion 120, resulting in a gently twisted shape. Here, counterclockwise refers to the direction of rotation around the Z axis from the Y axis to the X axis.

[0024] The lure 100 may be made of a metal (e.g., stainless steel, aluminum), etc. A cylindrical piece made of such a material is cut as the workpiece. The cutting process is performed by cutting from one end of the cylindrical piece, forming the triple-spiral-shaped front portion 110 first, and then processing the double-spiral-shaped rear portion 120. The fixing portion 130 is formed by applying a predetermined finishing process to the central portion remaining after cutting the front portion 110 and rear portion 120, and is integrally formed with the front portion 110 and rear portion 120.

[0025] In order to form a blade shape having two twisted surfaces 122 and 123, for example, as disclosed in paragraph

[0130] of Japanese Patent No. 6295040, the number of revolutions of the cutting blade (N T ) and the rotation speed of the workpiece (N W ) and the ratio (N T / N W ) to 1.999.

[0026] The dimensions of the workpiece in this embodiment are a cylinder with a total length of 70 mm and a diameter of 12 mm. Considering that it will be used to form a fishing lure, the diameter of the workpiece is preferably 16 mm or less, but is not limited to this.

[0027] There is no particular restriction on the depth of each of the three arc-shaped grooves 112, 113, and 114 formed on the outer periphery of the front part 110, but it is sufficient that the depth is such that the lure 100, when hit by the water current, can rotate in a triple spiral direction, i.e., clockwise.

[0028] Fig. 2 is a plan view of a lure according to a first embodiment of the present invention. The double helix shape of the rear portion 120 is gentle (i.e., rotates less than 90°), so it can be seen by simply looking at Fig. 1. In contrast, the triple helix shape of the front portion 110 has each spiral rotated about half a turn, making it difficult to understand the three spirals even when shown in a perspective view. Therefore, Fig. 2 uses two plan views (a plan view and a plan view rotated 90°) to explain the triple helix shapes 112, 113, and 114 of the front portion 110.

[0029] FIG. 1(a) is a view of the lure 100 from above (from the X axis). FIG. 1(b) is a view of the lure 100 from above in a state rotated 90° clockwise from the state of FIG. 1(a). When rotated in this manner, the Y axis of FIG. 1(b) faces from the front to the back of the page, and it should be noted that FIG. 1(b) is not a view of FIG. 1 drawn from the right side.

[0030] 1 and 2(a) and (b), it can be seen that the front portion 110 is provided with triple helical shapes 112, 113, and 114. Thus, the degree of twist in the front portion 110 is stronger than the degree of twist in the rear portion 120.

[0031] Fig. 3 is a cross-sectional view of the lure according to the first embodiment of the present invention. Fig. 3(a) shows a cross-section taken along the cross-section AA in Fig. 2(a). Fig. 3(b) shows a cross-section taken along the cross-section BB in Fig. 2(a).

[0032] 3(a), it can be seen that the cross-sectional structure of the triple spiral shapes 112, 113, and 114 of the front portion 110 is a roughly equilateral triangle. FIG. 3(b) shows that the cross-sectional structure of the double spiral shapes 122 and 123 of the rear portion 120 is a shape in which the bases of two convex parts with a gentle bulge in the center are joined together.

[0033] When explaining the manufacturing process of lure 100, it was stated that the cutting order is to first form triple helical shapes 112, 113, 114 of front portion 110 in a cylindrical workpiece, and then process double helical shapes 122, 123 of rear portion 120. This is because even if the triple helical shape is processed first, the cross-sectional shape is an approximately equilateral triangle, so that front portion 110 can be accurately fixed to the lathe chuck.

[0034] According to the first embodiment, when the lure 100 receives a water flow, the triple helix shapes 112, 113, and 114 of the front section 110 cause the lure 100 to rotate clockwise. Furthermore, the rear section 120, which rotates clockwise in the same direction as the front section 110 due to the fixed section 130, has double helix shapes 122 and 123 formed thereon, which rotate in a different direction from the triple helix shapes 112, 113, and 114. The rear section 120 receives water flow directly from the front section 110 in a direction different from the direction of the double helix, but is restricted from rotating in the direction of the double helix. Due to this restriction, the water flow that passes through the triple helix shape of the front section is not regulated when it passes through the double helix shape of the rear section. This allows the rear section 120 to wobble more like a tail wagging against the front section 110.

[0035] In this way, the rotation direction of the triple helix shape of the front portion 110 is clockwise, while the rotation direction of the double helix shape of the rear portion 120 is counterclockwise, which is different from the rotation direction of the front portion 110. Furthermore, since the rear portion 120 is configured to be restricted from rotating in the rotation direction of the rear portion 120, when the lure 100 as a whole rotates, it rotates in one direction (clockwise), and the lure 100 as a whole swings more widely from side to side. In other words, a larger wobbling motion can be achieved, making it easier to attract fish.

[0036] (Second embodiment) 4A and 4B are a perspective view and a plan view of a lure according to a second embodiment of the present invention. Fig. 4A is a view of the lure 200 seen from diagonally above right. Fig. 4B is a view of the lure 200 seen from above (X-axis). The second embodiment is significantly different from the first embodiment in that the shape of the second twisted portion at the rear is an eccentric rotor.

[0037] The lure 200 comprises a front portion 110, a rear portion 220, and a fixing portion 230 that fixes the front portion 110 and the rear portion 220. The front portion 110 has a triple helix shape that is basically the same as that of the first embodiment, and therefore a description thereof will be omitted. Note that the difference is that the triple helix shape of the first embodiment is clockwise, whereas the triple helix shape of the second embodiment is counterclockwise, but other points are the same.

[0038] The rear portion 220 has at its rear end a rear connection portion 221. The rear connection portion 221 is similar to the rear connection portion 121 described in the first embodiment, and therefore a description thereof will be omitted.

[0039] Eccentric rotors 222 and 223 are formed on the outer periphery of the rear portion 220. The eccentric rotors can be provided by cutting the outer periphery to form twisted shapes 222 and 223 with different pitches. The twisted shapes 222 and 223 with different pitches form an eccentric rotor that describes a gentle clockwise arc from the front to the rear of the rear portion 220. Here, an eccentric rotor refers to a rotor that does not have a single rotation axis (also referred to as a central axis) from the front to the rear of the rotor. In the case of Figure 4, the triple helix shape of the front portion 110 forms a single central axis from the front to the rear. This central axis is the axis connecting the front connecting portion 111 and the rear connecting portion 221 and corresponds to the Z-axis. In contrast, the eccentric rotors 222 and 223 rotate around the central axis (the Z-axis in Figure 4) with a predetermined eccentricity while moving rearward along the Z-axis. Therefore, the eccentric rotors 222 and 223 do not form a single rotation axis extending from the front to the rear of each pitch.

[0040] In this embodiment, the pitch interval of the shape 222 twisted by one turn at the first pitch is longer than the pitch interval of the shape 223 twisted by one turn at the second pitch. Note that the first pitch and the second pitch may be the same length, or the second pitch may be longer than the first pitch.

[0041] Fig. 5 is a cross-sectional view of a lure according to a second embodiment of the present invention. Fig. 5(a) shows a cross-section taken along the cross-section AA in Fig. 4(b). Fig. 5(b) shows a cross-section taken along the cross-section BB in Fig. 4(b).

[0042] 5(a), it can be seen that the cross-sectional structure of the triple spiral shapes 112, 113, and 114 of the front portion 110 is a substantially equilateral triangle, as in the first embodiment. FIG. 5(b) shows that the cross-sectional structure of the eccentric rotors 222 and 223 of the rear portion 220 is a circle.

[0043] In the case of the eccentric rotors 222 and 223, the center of each cross section is a point slightly away from the central axis (Z-axis) of the workpiece. The center point of each cross section moves in a gentle clockwise arc from the front to the rear of the rear portion 220. Therefore, each cross section itself is circular.

[0044] The order of cutting the lure 200 is the same as in the first embodiment, in that the triple spiral shapes 112, 113, and 114 of the front portion 110 are first machined on the cylindrical workpiece, and then the eccentric rotor shapes 222 and 223 of the rear portion 220 are machined. This is because even if the triple spiral shape is machined first, the cross-sectional shape is a substantially equilateral triangle, so the front portion 110 can be accurately fixed at three points to the lathe chuck. If the eccentric rotor shapes 222 and 223 of the rear portion 220 were machined first, the central axes of the eccentric rotors would be different for each cross-section and would not be uniquely determined like the central axis of the front portion 110 (i.e., the Z-axis), making it extremely difficult to control the cutting machine.

[0045] According to the second embodiment, when the lure 200 is subjected to a water flow, the triple helix shapes 112, 113, and 114 of the front section 110 cause the lure 200 to rotate counterclockwise. Furthermore, the rear section 220, which rotates counterclockwise in the same direction as the front section 110 due to the fixed section 230, has eccentric rotors 222 and 223 formed thereon, which rotate in a direction different from that of the triple helix shapes 112, 113, and 114. The rear section 220 directly receives the water flow from the front section 110, which rotates in a direction different from that of the eccentric rotors, but is restricted from rotating in the same direction as the eccentric rotors. Due to this restriction, the water flow that passes through the triple helix shapes of the front section is not regulated, i.e., is not rectified, when it passes through the eccentric rotor of the rear section. This allows the rear section 220 to wobble more like a tail wagging against the front section 110.

[0046] As in the first embodiment, the lure 200 exhibits a larger lateral swinging movement overall, that is, a larger wobbling motion can be realized, which makes it easier to attract fish.

[0047] (Third embodiment) 6 is a plan view of a lure according to a third embodiment of the present invention. The third embodiment differs from the first embodiment in that a decorative portion is provided on the front side of the front part.

[0048] The lure 100' comprises a front portion 110', a rear portion 120, and a fixing portion 130 that fixes the front portion 110' and the rear portion 120. The front portion 110' has a decorative portion 119 between the front connecting portion 111 and the triple helix shapes 112, 113, 114.

[0049] First, one end of a cylindrical material is turned to form a step on the front side of the front portion 110' that has a diameter smaller than that of the cylindrical work material, thereby forming the decorative portion 119. Next, the work material is cut so that the triple spiral shapes 112, 113, 114 start from a part of the decorative portion 119, thereby forming the triple spiral shapes 112, 113, 114.

[0050] When the lure 100' rotates in response to the water current, light in the water is diffused by the steps of the decorative portion 119. The decorative portion 119 is also called a reflecting portion.

[0051] According to the third embodiment, as in the first embodiment, the lure 100' as a whole has a larger lateral swinging motion, i.e., it can achieve a larger wobbling motion, which makes it easier to attract fish. Furthermore, the decorative portion 119 causes diffused reflection, which further enhances the effect of attracting fish.

[0052] (Fourth embodiment) 7 is a plan view of a lure according to a fourth embodiment of the present invention. The fourth embodiment differs from the first embodiment in that the front and rear portions are not integrally formed.

[0053] The lure 300 comprises a front portion 110, a rear portion 120, and a fixing portion 310 that fixes the front portion 110 and the rear portion 120 together. As in the first embodiment, the front portion 110 has a front connecting portion 111 at its tip, and first twisted portions 112, 113, and 114 in a clockwise triple helix shape are formed on its outer periphery. Furthermore, a first connecting portion 115 is provided at the rear end of the front portion 110. A hole is formed in the first connecting portion 115.

[0054] Similar to the first embodiment, rear portion 120 has rear connecting portion 121 at its rear end, and second twisted portions 122, 123 in a counterclockwise double spiral shape are formed on its outer periphery. Furthermore, a second connecting portion 124 is provided at the front end of rear portion 120. A hole is provided in second connecting portion 124.

[0055] The fixing ring 311 passes through a hole in the first connecting portion 115 and a hole in the second connecting portion 124. The fixing ring 311 connects the front portion 110 and the rear portion 120 in series, and fixes the rear portion 120 so that it is forced to rotate in the same direction as the front portion 110, regardless of the direction of the spirals of the double helix shapes 122, 123. The first connecting portion 115, the second connecting portion 124, and the fixing ring 311 are collectively referred to as the fixing portion 310.

[0056] In lure 300, front portion 110 and rear portion 120 are fixed by fixing portion 310, so when triple-helix first twisted portions 112, 113, 114 receive water current and rotate clockwise, double-helix second twisted portions 122, 123 also rotate clockwise, similar to the first embodiment. That is, front portion 110 and rear portion 120 rotate in the same direction.

[0057] According to the fourth embodiment, as in the first embodiment, the lure 300 as a whole has a larger swinging movement from side to side, i.e., it can achieve a larger wobbling motion, making it easier to attract fish. Furthermore, the front portion 110 and the rear portion 120 do not need to be integrally molded.

[0058] In the first embodiment, the lure 100 is manufactured by cutting a single cylindrical piece of metal material. In contrast, in the fourth embodiment, the lure 300 does not need to be integrally molded, so the front section 110 and the rear section 120 can be manufactured separately. For example, first, molds for the front section 110 and the rear section 120 are made, and then mass production is possible by injection molding using ABS resin or the like.

[0059] When molding with a mold, there is no need to consider accurate fixing to the lathe chuck, so it is possible to make the front part a double-helix blade and the rear part an eccentric rotor, which increases the number of combinations of front and rear parts. Also, even if the torsion degree of the front part is weaker than that of the rear part, the rear part will wobble like a tail.

[0060] (Fifth to Eighth Embodiments) In the fourth embodiment, a lure is manufactured by injection molding. By using injection molding, various modified lures can be manufactured. Various modified examples (fifth to eighth embodiments) of manufacturing a lure by injection molding will be explained using Figs. 8 to 11. Note that the same reference numerals are used for the parts explained in the first to fourth embodiments, and duplicate explanations will be omitted.

[0061] Fig. 8 is a plan view of a lure according to a fifth embodiment of the present invention. The lure 400 in Fig. 8(a) comprises a front portion 110, a rear portion 110-1 that rotates in a direction different from that of the front portion 110, and a fixing portion 410 that fixes the front portion 110 and the rear portion 110-1. The rear portion 110-1 has a triple helix shape that rotates counterclockwise from the front to the rear.

[0062] The lure 400 may be formed by cutting instead of injection molding. When formed by cutting, the fixing part 410 is formed by performing a predetermined finishing process on the central part remaining after cutting the front part 110 and the rear part 110-1, and is formed integrally with the front part 110 and the rear part 110-1.

[0063] The lure 400' in FIG. 8(b) is manufactured by injection molding into a front portion 110 and a rear portion 110-1, and the front portion 110 and the rear portion 110-1 are fixed together by a fixing portion 310.
