Description

[Technical Field]

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

[0002] Conventionally, a type of lure known as a wire bait has been known as a lure used in lure fishing. The basic structure of a wire bait is formed from a wire (metal wire), and a typical wire bait is a spinner bait that has long been known. A spinner bait has a structure in which a head portion that functions as a sinker is fixed to one end of a substantially L-shaped wire together with a hook, and a blade that functions as a rotor is connected to the other end of the wire (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3529457 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional wire baits, the wire and head are fixed, so the head and wire move as a unit when the lure's position changes. Therefore, a change in the lure's position can change the relative position of the head (which is the center of gravity) and the blade, potentially resulting in an undesirable swimming action. The position of a wire bait changes depending on various factors. For example, as the retrieve speed (the speed at which the lure is pulled) increases, the resistance generated by the water current on the blade increases, causing the head to change its position so that it faces upward (i.e., the blade moves backward). Furthermore, when a wire bait is pulled in deep water, it is pulled upward by the line, which also causes the head to change its position so that it faces upward.

[0005] As described above, conventional wire baits have the problem that they are easily affected by changes in position because the head and wire are fixed, making it difficult to use conventional wire baits stably at deep ranges regardless of the retrieve speed.

[0006] The present invention has been made in view of the above-mentioned problems, and one of its objects is to provide a lure that can be used stably at a deep range regardless of the retrieval speed. [Means for solving the problem]

[0007] A lure according to one embodiment of the present invention comprises a head portion, a hook attached to the head portion, an arm portion rotatably connected to the head portion with the left-right direction of the head portion as a rotation axis, and a blade connected to the arm portion. The arm portion may include an upper arm and a lower arm. In this case, the upper arm is connected to the blade, and the lower arm is connected to the head portion. [Effects of the Invention]

[0008] According to one embodiment of the present invention, it is possible to provide a lure that can be used stably at deep ranges regardless of the retrieval speed. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a diagram showing the configuration of the blade of the lure in the first embodiment. [Figure 3] FIG. 10 is a diagram showing the configuration of a lure in a second embodiment.

[Figure 5] FIG. 10 is a diagram showing the configuration of a lure in a fourth embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a lure according to one embodiment of the present invention will be described with reference to the drawings. However, the lure of the present invention can be embodied in many different aspects, and should not be construed as being limited to the description of the example shown below.

[0011] Furthermore, in this specification, "up" refers to the direction in which buoyancy acts when a lure is used, and "down" refers to the opposite direction to "up" (i.e., the direction in which gravity acts). In other words, when a lure is used underwater, the direction in which the water surface is located is "up," and the direction in which the lake or river bottom is located is "down." Furthermore, "front" and "rear" refer to the direction in which the lure moves, and the opposite direction, respectively. Furthermore, "left" and "right" refer to the left and right sides when facing "front." In the drawings referred to in the following description, the first direction (D1 direction) is the front-to-back direction, the second direction (D2 direction) perpendicular to the first direction is the up-down direction, and the third direction (D3 direction) perpendicular to the first and second directions is the left-to-right direction.

[0012] First Embodiment FIG. 1 is a diagram showing the configuration of a lure 100 in a first embodiment. Specifically, FIG. 1(A) shows a right side view of the lure 100, and FIG. 1(B) shows a top view of the lure 100. FIG. 1(C) is an enlarged view of a head portion 110 of the lure 100. As shown in FIGS. 1(A) and 1(B), the lure 100 includes the head portion 110, a hook 120, an arm portion 130, a blade 140, and a rubber skirt 150. The lure 100 is a type of lure known as a wire bait. The lure 100 of this embodiment resembles a spinner bait, but strictly speaking, it differs from a spinner bait in that the blade 140 does not rotate.

[0013] The head portion 110 functions as a sinker. The head portion 110 is made of a metal material, and in this embodiment, lead is used. However, other metal materials such as tungsten and bismuth may be used as the metal material. There are no particular restrictions on the shape of the head portion 110, but it is usually shaped so that the front is thinner than the rear so as to deflect water. Although not shown in the drawings, the head portion 110 of this embodiment has an outer shape of an inverted triangle or an inverted trapezoid when viewed from the front. The head portion 110 of this embodiment has a ring-shaped member 116 at the rear. The ring-shaped member 116 is an eye for attaching additional parts (e.g., a hook, a sinker, a blade, etc.), but it can be omitted.

[0014] The hook 120 is a so-called fishhook. In this embodiment, the hook 120 is fixed to the rear of the head portion 110. In this embodiment, the head portion 110 is fixed to a shank portion of the hook 120, thereby forming the head portion 110 and the hook 120 into one unit. However, this is not limiting, and the hook 120 may be movably attached to the head portion 110.

[0015] The arm portion 130 is made of wire (metal wire) and functions as a member that connects the head portion 110 and the blade 140, as well as a connecting member that connects the lure 100 and the line. The arm portion 130 includes an upper arm 132 located on the upper side and a lower arm 134 located on the lower side. A line eye 136 formed by bending a wire is provided between the upper arm 132 and the lower arm 134. The line is tied to the line eye 136. The line eye 136 is configured so that it does not widen even if the size of the blade 140 is increased by soldering its base.

[0016] As shown in FIG. 1(A), a blade 140 is connected to the upper arm 132. The upper arm 132 has a bent portion 132a between the line eye 136 and the blade 140. The upper arm 132 extends substantially upward from the line eye 136 to the bent portion 132a, and extends substantially backward from the bent portion 132a to the blade 140. By configuring the upper arm 132 in this manner, it is possible to prevent problems such as the blade 140 hitting the line and causing damage when the lure 100 is in use.

[0017] The head unit 110 is connected to the lower arm 134. The lower arm 134 is connected to the head unit 110 so as to be rotatable about an axis 10 extending in the left-right direction of the head unit 110. The connection structure between the head unit 110 and the lower arm 134 will be described later.

[0018] The blade 140 is made of a thin plate-like member and is connected to the upper arm 132. In this embodiment, the blade 140 is made of a plate-like metal member, but this is not limiting and the blade 140 can also be made of a plastic material. The blade 140 in this embodiment is a swinging member that swings in response to the water flow without rotating.

[0019] Fig. 2 is a diagram showing the configuration of the blade 140 of the lure 100 in the first embodiment. Specifically, Fig. 2(A) is a front view showing the configuration of the blade 140 of the lure 100, and Fig. 2(B) is a side view showing the configuration of the blade 140.

[0020] As shown in FIG. 2(A), the blade 140 of this embodiment has two through holes 142a and 142b. As shown in FIG. 1(A), in this embodiment, the end of the upper arm 132 is bent and inserted into the through holes 142a and 142b. That is, the two through holes 142a and 142b function as a connecting portion that connects the upper arm 132 and the blade 140. However, this connecting method is one example and is not limited to this. For example, a component (e.g., a member such as a hook hanger) through which the upper arm 132 can be inserted may be attached to the blade 140.

[0021] 2(B), the blade 140 of this embodiment has a bent portion 140a. Specifically, in FIG. 2(A), the blade 140 is bent to form a bent line 144 that passes between the two through holes 142a and 142b (in other words, passes through the connecting portion with the upper arm 132) and extends in the width direction. The angle of bending (θ) at the bent portion 140a is preferably adjusted within a range of 5 to 30 degrees, but is not limited thereto. The upper arm 132 is connected to the blade 140 via a connecting portion located at the bent portion 140a of the blade 140. By having the bent portion 140a, the blade 140 of this embodiment can more easily grab water when the lure 100 starts to move, improving the response of the lure 100 in its initial movement.

[0022] As shown in FIGS. 2A and 2B, the length (L1) from the bending line 144 to the upper end 140b of the blade 140 is longer than the length (L2) from the bending line 144 to the lower end 140c of the blade 140. That is, the positions of the connecting portions connecting the upper arm 132 and the blade 140 (i.e., the positions of the through-holes 142a and 142b) are asymmetrical in the vertical direction. In this case, when the lure 100 is in use, the upper portion of the blade 140 (the portion having length L1) receives more water flow than the lower portion (the portion having length L2), and functions like the lip of a plug lure. Therefore, when the lure 100 is pulled through the water, the blade 140 functions as a resistance body (a so-called lip) that deflects the water flow diagonally upward, thereby working to push the lure 100 downward. In other words, the blade 140 serves to prevent the lure 100 from floating upward.

[0023] The rubber skirt 150 is made of a bundle of elastic linear members and is disposed behind the head portion 110. In this embodiment, the rubber skirt 150 is made of rubber made of a silicone material, but is not limited to this. The rubber skirt 150 functions as an attractant that attracts fish and also has the effect of reducing the presence of the hook 120. However, in the lure 100 of this embodiment, the rubber skirt 150 is not an essential component and can be omitted.

[0024] (Head and arm connection structure) As described above, in the lure 100 of this embodiment, the arm portion 130 is connected to the head portion 110 so as to be rotatable around the left-right direction (D3 direction) of the head portion 110 as the rotation axis. That is, as shown in Fig. 1(A) , in a side view, the entire arm portion 130 rotates clockwise or counterclockwise with the lower arm 134 as the radial direction. In other words, it can be said that the rotation locus formed when the arm portion 130 rotates is included in a plane perpendicular to the left-right direction (D3 direction) of the head portion 110.

[0025] As shown in FIG. 1(C), the head unit 110 of this embodiment includes a head main body 112 and a pin member 114. A notch 112a is provided at the front end of the head main body 112 to accommodate an annular portion 134a (see FIG. 1(A)) provided at the end of the lower arm 134. A through hole 112b extending in the left-right direction (direction D3) is provided at the side of the head main body 112 so as to cross the notch 112a. The diameter of the through hole 112b may be large enough to allow the pin member 114 to be inserted therethrough.

[0026] As shown in FIG. 1D, a protective member 118 made of a material stronger than the head body 112 may be disposed at the tip of the head body 112, and a notch 112a may be provided in the protective member 118. In this embodiment, the head body 112 is made of lead, which may gradually wear away due to contact with the lower arm 134, causing the notch 112a to widen. In the structure shown in FIG. 1D, the protective member 118 may be made of a metal material stronger than lead, such as tungsten or bismuth, to suppress wear due to contact with the lower arm 134. However, the protective member 118 may be replaced with a head body 112 having a wider area. Although FIG. 1D illustrates a U-shaped protective member 118, the notch 112a may instead be formed by arranging two plate-shaped protective members 118 at a distance from each other.

[0027] The annular portion 134a provided at the end of the lower arm 134 is disposed inside the cutout portion 112a of the head main body 112. Then, with the annular portion 134a disposed inside the cutout portion 112a, the pin member 114 is inserted into the through-hole 112b. At this time, the pin member 114 is also inserted into the annular portion 134a. As a result, the arm portion 130 is connected to the head portion 110 so as to be rotatable around the pin member 114, which extends in the left-right direction, as a rotation axis. The pin member 114 may be fixed to the head portion 110 with an adhesive or the like.

[0028] In the structure of this embodiment, the arm unit 130 rotates around the annular portion 134a (strictly speaking, the pin member 114) disposed inside the cutout portion 112a. Therefore, the lower arm 134 rotates along the cutout portion 112a, and the movement of the arm unit 130 in the left-right direction is restricted. In other words, the rotation of the arm unit 130 around the vertical direction (direction D2) of the head unit 110 as the rotation axis is restricted. However, because the width of the cutout portion 112a in the left-right direction is designed to be slightly wider than the width of the annular portion 134a, there may be some play in the movement of the arm unit 130 in the left-right direction.

[0029] As described above, in the fishing lure 100 of this embodiment, the arm portion 130 is connected to the head portion 110 so as to be rotatable around the left-right direction of the head portion 110 as a rotation axis. With this structure, even if the orientation of the head portion 110 changes due to a change in water depth, or if the resistance received by the blade 140 changes due to a change in retrieve speed, the arm portion 130 rotates in response to the change and corrects the positional relationship between the head portion 110 and the blade 140 to an appropriate state, thereby maintaining the action of the fishing lure 100 in an appropriate state. As a result, the fishing lure 100 of this embodiment can be used stably at deep ranges regardless of the retrieve speed.

[0030] In this embodiment, the blade 140 swings without rotating when subjected to the water current, and functions as a resistance body (lip) that propels the lure 100 downward. The movable wire structure of this embodiment is particularly effective when combined with such a blade 140. This point will be explained below.

[0031] First, as a comparative example, assume that the arm portion 130 is fixed to the head portion 110 in the fishing lure 100 shown in FIG. 1 . In this case, as the retrieve speed increases, the posture of the fishing lure 100 changes, and at some point the action of the blade 140 breaks down. Specifically, if the retrieve speed increases beyond a certain level, the blade 140 may no longer be able to properly receive the water flow and may no longer function as a lip. In this state, the action of the fishing lure 100 breaks down, and it may fall over and rotate, or deviate from its normal trajectory.

[0032] In contrast, in the case where the arm portion 130 is movably connected to the head portion 110 as in this embodiment, as the retrieval speed increases, the positional relationship between the head portion 110 and the blade 140 changes accordingly, and it is possible to always maintain an appropriate positional relationship between the head portion 110 and the blade 140. Due to this action, the lure 100 of this embodiment can maintain a stable action regardless of the retrieval speed.

[0033] Furthermore, when the lure 100 of this embodiment is used in a deep water range, even if the orientation of the head portion 110 changes, the positional relationship between the head portion 110 and the blade 140 is kept appropriate by following the change. As a result, the blade 140 functions normally as a lip, and prevents the lure 100 from floating upward. This allows the lure 100 of this embodiment to be used stably in a deep water range.

[0034] As described above, the lure 100 of this embodiment has a movable wire structure that does not fix the head portion 110 and the arm portion 130, so it can be used stably at deep ranges regardless of the retrieval speed. In particular, the lure 100 of this embodiment swings without rotating when exposed to water currents, and is equipped with the blade 140 that functions as a lip that propels the lure 100 downward, so it is possible to achieve a stable action at deep ranges while suppressing the lure 100 from floating up.

[0035] (Variation) In this embodiment, an example has been shown in which the blade 140 is applied to a wire bait of a type in which it does not rotate but oscillates, but the present invention is not limited to this example and can also be applied to a spinner bait in which the blade rotates.

[0036] Second Embodiment In this embodiment, an example will be described in which the head unit and the arm unit are connected by a structure different from that of the first embodiment. In this embodiment, the differences from the first embodiment will be described, and the same components as those in the first embodiment will be designated by the same reference numerals and will not be described again.

[0037] Fig. 3 is a diagram showing the configuration of a lure 200 in a second embodiment. Specifically, Fig. 3(A) shows a right side view of the lure 200, and Fig. 3(B) shows a top view of the lure 200. In the lure 200 of this embodiment, a ring-shaped member 214 provided on a head body 212 of the head portion 210 is used to connect the head portion 210 and the arm portion 130.

[0038] The annular member 214 is provided at the front end of the head body 212 of the head unit 210. A center line passing through the center of the annular member 214 extends in the up-down direction (direction D2). Therefore, the arm unit 130 of this embodiment is rotatable around the left-right direction (direction D3) of the head unit 210 as a rotation axis, and can also be rotated around the up-down direction (D2) of the head unit 210 as a rotation axis. In other words, the arm unit 130 of this embodiment has a higher degree of freedom of rotation than the arm unit 130 of the first embodiment.

[0039] In this embodiment, the arm unit 130 is also rotatable around the left-right direction of the head unit 210 as a rotation axis, and therefore the same effects as in the first embodiment are achieved.

[0040] Third Embodiment In this embodiment, an example will be described in which a means for restricting the rotation of the arm is provided in the head unit or the arm unit. In this embodiment, the differences from the first embodiment will be described, and the same components as in the first embodiment will be assigned the same reference numerals and will not be described again.

[0041] Fig. 4 is a cross-sectional view showing the configuration of head portions 310a to 310c of the third embodiment. Specifically, Fig. 4(A) to Fig. 4(C) show side cross-sectional views of head portions 310a to 310c, respectively, taken along the center line in the front-rear direction (D1 direction).

[0042] The structure shown in FIG. 4(A) is an example in which a means for restricting the rotation of the arm unit 130 is provided on the head unit 310a. In FIG. 4(A), the shaded area is the inner wall surface of the cutout portion 312a corresponding to the cutout portion 112a shown in FIG. 1(C). In the structure shown in FIG. 4(A), when the arm unit 130 rotates downward, the lower arm 134 abuts against the lower edge 22a of the cutout portion 312a, restricting the rotation. Conversely, when the arm unit 130 rotates upward, the lower arm 134 abuts against the tip-side edge 22b of the cutout portion 312a, restricting the rotation.

[0043] In this way, the shape of the notch 312a provided in the head 310a can limit the rotation of the arm 130. In this case, by controlling the positions of the lower edge 22a and the upper edge 22b of the notch 312a, it is possible to limit the rotation of the head 310a around the left-right direction as the rotation axis to a predetermined angle range.

[0044] 4(A), the structure shown in Fig. 4(B) is an example in which a means for limiting the rotation of the arm unit 130 is provided on the head unit 310a, but a rotation limiting member 314 is provided inside the cutout portion 312b. The rotation limiting member 314 is disposed above the lower edge 22a of the cutout portion 312b. Therefore, the lower arm 134 comes into contact with the rotation limiting member 314, thereby limiting its downward rotation.

[0045] In the structure shown in FIG. 4(B), it is preferable to use a metal material, such as tungsten or bismuth, that is harder than lead for the rotation-limiting member 314. Because lead is one of the softer metals, if the rotation of the lower arm 134 is limited using the edge 22a of the cutout portion 312b, the position of the edge 22a may shift over use, potentially changing the range of rotation. In contrast, in the structure shown in FIG. 4(B), by using a metal material for the rotation-limiting member 314 that is harder than the material of the head portion 310b, it is possible to limit the rotation of the lower arm 134 without changing the range of rotation of the lower arm 134.

[0046] 4(C) is an example in which the arm unit 130 is provided with a means for limiting the rotation of the arm unit 130. Specifically, a bent portion 134b is provided near the end of the lower arm 134, and the portion of the lower arm 134 between the annular portion 134a and the bent portion 134b is used as the means for limiting the rotation. In this case, when the portion between the annular portion 134a and the bent portion 134b abuts against the lower edge 22a of the notch portion 312c, the portion of the arm unit 130 in front of the bent portion 134b (such as the upper arm 132 and the line eye 136) does not move down more than necessary, and as a result, the rotation of the arm unit 130 can be limited.

[0047] As described above, the lure of this embodiment has a means for restricting the rotation of the arm portion 130, either in the head portion (head portion 310a or 310b) or in the arm portion 130 (specifically, the lower arm 134). This prevents the arm portion 130 from rotating more than necessary when casting (throwing the lure), thereby reducing air resistance in the air and increasing the casting distance.

[0048] The structure of the means for restricting the rotation of the arm unit 130 described in this embodiment is not limited to the structure shown in Figures 4(A) to 4(C). Any structure can be applied as long as it can restrict the rotation of the arm unit 130 within a predetermined angle range.

[0049] Fourth Embodiment In this embodiment, an example will be described in which a means for preventing snagging is provided on the arm portion. In this embodiment, the differences from the first embodiment will be described, and the same components as those in the first embodiment will be assigned the same reference numerals and will not be described again.

[0050] Fig. 5 is a diagram showing the configuration of a lure 300 in a fourth embodiment. Specifically, Fig. 5(A) shows a right side view of the lure 300, and Fig. 5(B) shows a top view of the lure 300. As shown in Fig. 5(A), the lure 300 of this embodiment has a guard means 338 for preventing the arm portion 330 from getting snagged. Specifically, the guard means 338 is provided on the lower arm 334 of the arm portion 330.

[0051] In this embodiment, the guard means 338 is composed of two guard wires 338a and 338b made of wire (metal wire). Specifically, as shown in Fig. 5(A), one ends of the guard wires 338a and 338b are fixed near the line eye 336, and the other ends are positioned diagonally downward. In this case, as shown in Fig. 5(B), in top view, the two guard wires 338a and 338b extend diagonally from near the line eye 336 to form a substantially V-shape.

[0052] As described above, by arranging the guard means 338 from the line eye 336 to the vicinity of the head portion 110, when the lure 300 is used at a deep range, it becomes easy to avoid getting snagged on obstacles (sunken ships, trees, artificial structures, etc.) that exist near the bottom of a lake or river. Furthermore, the lure 300 of this embodiment has a structure in which the upper arm 332 extends diagonally upward from the line eye 336 and the guard lines 338a and 338b extend diagonally downward, which has the advantage of providing high performance in passing through aquatic plants such as weeds.

[0053] Fifth Embodiment In the first to fourth embodiments, a wire bait has been described as an example of a lure to which the present invention is applied, but the present invention is not limited to this and can also be applied to other types of lures.

[0054] For example, the present invention can be applied to sinking lures that can be used at deep depths, such as metal jigs, rubber jigs, jig head rigs (lures with a worm or the like attached to a jig head), etc. When a lure is formed by connecting a rotatable arm to a part of the metal jig and attaching the blade 140 described in the first embodiment to one end of the arm, the metal jig can be used stably at deep depths.

[0055] Furthermore, the present invention is not limited to lures for freshwater fish, but may also be applied to lures for saltwater fish. When the present invention is applied to the metal jig described above, it is particularly suitable as a lure for saltwater fish.

[0056] Although the present invention has been described above with reference to the drawings, the present invention is not limited to the above-described embodiments and can be modified as appropriate without departing from the spirit of the present invention. Furthermore, the above-described embodiments can be combined with each other as long as no technical contradiction occurs. [Explanation of symbols]
