Description

Technical Field

[0001] This utility model relates to the field of fishing gear, and in particular to a lure and fishing tackle. Background Technology

[0002] Some lures on the market are equipped with a center-of-gravity transfer system, which shifts the lure's center of gravity backward when cast, thus providing better targeting and allowing for longer cast distances. For example, the publication text of Japanese Patent Publication No. JP08000093U.

[0003] Before the lure is cast, it spins at high speed. At this time, the sliding weight needs a large centripetal force to move backward, which usually causes the lure's center of gravity to shift towards the tail. After the lure is released and cast, the centripetal force disappears, and the sliding weight returns to the front under the action of the spring force inside the lure, ensuring the balance of the lure's center of gravity after it hits the water.

[0004] After prolonged use, the spring force may weaken, or the sliding weight may not be able to return to the front end completely due to friction. This may disrupt the balance of the lure, affect its swimming posture, and ultimately affect the fishing experience.

[0005] Meanwhile, traditional lures, apart from their weight transfer system, have a relatively balanced overall weight distribution to ensure a good swimming action after entering the water. However, this uniform distribution also makes it difficult to concentrate the weight on the tail during casting, limiting the potential for improving casting distance and accuracy. Utility Model Content

[0006] The technical problem to be solved by this utility model is to solve at least one of the technical problems mentioned above.

[0007] The solution to the technical problem of this utility model is:

[0008] A lure includes a spring, a first counterweight, and a lure body extending in a front-rear direction. The lure body has a counterweight channel extending obliquely forward and downward. The first counterweight is disposed in the counterweight channel and can slide relative to the first counterweight and the counterweight channel. The spring is disposed in the counterweight channel and is located between the upper ends of the first counterweight and the counterweight channel.

[0009] As a further improvement to the above technical solution, the spring is disposed between the upper end of the counterweight channel and the first counterweight block, and the end of the spring facing away from the first counterweight block is fixedly connected to the artificial bait body.

[0010] As a further improvement to the above technical solution, the artificial bait also includes several counterweight balls, with the first counterweight block disposed between the spring and the counterweight balls.

[0011] As a further improvement to the above technical solution, the inner wall of the counterweight channel extends into a step, forming a limiting hole at the step. The step of the counterweight channel is used to abut against the first counterweight block, and the counterweight ball can pass through the limiting hole.

[0012] As a further improvement to the above technical solution, the rear end of the artificial bait body is provided with a receiving space, and the artificial bait also includes a plurality of second counterweights, which are disposed in the receiving space.

[0013] As a further improvement to the above technical solution, the rear end of the counterweight channel extends above the accommodating space.

[0014] As a further improvement to the above technical solution, a cavity is provided inside the artificial bait body, and the cavity is located above the counterweight channel.

[0015] As a further improvement to the above technical solution, the first counterweight is cylindrical, and the axis of the cylindrical first counterweight and the length direction of the artificial bait body form an angle α, the angle α being an acute angle, and the angle α being greater than or equal to 3.5°.

[0016] As a further improvement to the above technical solution, the artificial bait body includes a front shell arranged in the front-to-back direction and a rear shell connecting the front shell, wherein the width between the left and right sides of the front shell gradually increases from front to back.

[0017] As a further improvement to the above technical solution, the openings on the left and right sides of the front shell are oriented towards the rear shell at an angle β, wherein the angle β is an acute angle and is greater than or equal to 5°.

[0018] This utility model also provides a fishing tackle, which includes a fishing rod and a lure of any of the above-mentioned technical solutions.

[0019] The beneficial effects of this invention are as follows: Compared to the traditional weight transfer system of artificial lures, the inclined counterweight channel and the coordinated design of the spring thrust direction of this invention utilize gravity to offset part of the frictional resistance during the reset of the first counterweight. This reduces the risk of spring force weakening or the first counterweight becoming stuck due to long-term use, thus avoiding the problem of unbalanced center of gravity. Simultaneously, through this structural design, the first counterweight resets more thoroughly, and the center of gravity of the lure body is closer to the designed equilibrium point after entering the water, resulting in a more natural swimming posture (such as swing amplitude and sinking / floating stability), thereby increasing its attractiveness to target fish.

[0020] The fishing tackle of this utility model includes the aforementioned artificial lure, which is convenient to use and allows for precise control when casting the artificial lure. Attached Figure Description

Detailed Implementation

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0027] Some lures on the market are equipped with a center-of-gravity transfer system, which shifts the lure's center of gravity backward during casting, providing better targeting and allowing for longer throws. Before casting, the lure spins at high speed, causing the sliding weight to move backward under significant centrifugal force, typically shifting the lure's center of gravity towards the tail. Once released and cast, the centripetal force disappears, and the sliding weight returns to the front under the force of an internal spring, ensuring the lure's balance upon landing. However, with prolonged use, the spring force may weaken, or the sliding weight may fail to return completely to the front due to friction. This can disrupt the lure's balance, affecting its swimming posture and ultimately impacting the fishing experience.

[0028] like Figures 1 to 3As shown, this utility model provides a lure, which includes a spring 1, a first counterweight 2, and a lure body 3 extending in the front-to-back direction. The lure body 3 has a counterweight channel 4 extending obliquely forward and downward. The first counterweight 2 is disposed in the counterweight channel 4, and the first counterweight 2 and the counterweight channel 4 can slide relative to each other. The spring 1 is disposed in the counterweight channel 4, and the spring 1 is disposed between the upper end of the first counterweight 2 and the counterweight channel 4.

[0029] The artificial bait in this invention is based on a dynamic center of gravity adjustment mechanism. It achieves active control of the center of gravity during the casting and water landing stages through the synergistic effect of the inclined counterweight channel 4, the spring 1, and the first counterweight block 2.

[0030] When the lure body 3 is rotated at high speed (e.g., by casting), the first counterweight 2 is subjected to centrifugal force. The first counterweight 2 slides backward and upward along the counterweight channel 4 from the front end (the lower end). Due to the inclined design of the channel, the sliding path of the first counterweight 2 forms an angle with the direction of the centripetal force, so the first counterweight 2 must simultaneously overcome the force of the spring 1 and the component force of the inclined channel. After stabilization, the center of gravity shifts towards the tail of the lure, improving the directionality and distance of the casting.

[0031] After the lure body 3 is released and thrown, the centripetal force disappears. The elastic potential energy generated by the deformation of the spring 1 is converted into elastic force, pushing the first counterweight 2 to return to its original position forward and downward along the inclined channel. The inclined direction of the counterweight channel 4 is coordinated with the direction of the spring 1's thrust. The design of the inclined counterweight channel 4 makes the return path of the first counterweight 2 more in line with mechanical balance, reduces friction loss during the sliding process, and ensures that the first counterweight 2 can return to its initial position more efficiently and completely, restoring the lure's center of gravity balance.

[0032] Compared to the traditional weight transfer system of artificial lures, the coordinated design of its tilted counterweight channel 4 and the thrust direction of the spring 1 utilizes gravity to offset some of the frictional resistance when the first counterweight 2 resets. This reduces the risk of the spring 1 weakening or the first counterweight 2 becoming stuck due to long-term use, thus avoiding imbalance. Simultaneously, this structural design allows for a more thorough reset of the first counterweight 2, resulting in the lure body 3 having a center of gravity closer to the designed equilibrium point after entering the water. This leads to a more natural swimming posture (such as swing amplitude and sinking / floating stability), enhancing its attractiveness to target fish.

[0033] While it is possible to implement this solution without fixing the upper end of spring 1, lateral displacement or torsion may occur when spring 1 is compressed. Therefore, in one embodiment, spring 1 is positioned between the upper end of the counterweight channel 4 and the first counterweight block 2, with the end of spring 1 facing away from the first counterweight block 2 fixedly connected to the artificial bait body 3. After the upper end of spring 1 is fixed, its compression and release processes only move along the direction of the counterweight channel 4, avoiding lateral displacement or torsion caused by the lack of a fixed end, ensuring that the storage and release of elastic potential energy are fully applied to the first counterweight block 2, and improving the reliability of the reset action.

[0034] Furthermore, under the constraint of the fixed end of spring 1, the direction of the spring 1's thrust is aligned with the tilt direction of the counterweight channel 4, reducing the additional resistance when the first counterweight 2 is reset (such as friction caused by the tilt of spring 1). Even if the force of spring 1 weakens after long-term use, the guiding effect of the fixed end can still reduce the risk of the first counterweight 2 getting stuck and extend the life of the dummy's balance performance.

[0035] Once the upper end of spring 1 is fixed, the backward movement of the counterweight during throwing is directly determined by the maximum compression of spring 1 (rather than the uncontrollable compression caused by the free sliding of spring 1), avoiding the problem of excessive backward movement or insufficient sliding of the counterweight, ensuring that the backward movement of the center of gravity matches the throwing requirements, and improving the stability of throwing distance and direction.

[0036] When the first counterweight 2 moves to the lower front end of the counterweight channel 4, due to the shape limitation of the first counterweight 2 itself, there may still be space in front of the first counterweight 2. In order to improve the utilization of space, in one embodiment, the lure also includes several counterweight balls 6, with the first counterweight 2 located between the spring 1 and the counterweight balls 6. In addition, the contact between the counterweight balls 6 and the counterweight channel 4 is point contact or line contact, and the rolling friction is much less than the sliding friction of the first counterweight 2, reducing the energy loss of backward movement during casting and reset upon landing, making the center of gravity adjustment more sensitive and efficient. The independent rolling characteristics of the first counterweight balls 6 enable them to autonomously adjust their position according to the slight changes in the lure's posture in the air or water (such as rotation and collision), assisting the first counterweight 2 to achieve more precise center of gravity compensation, making the lure's swimming posture (such as swing frequency and sinking angle) closer to that of real fish, and increasing its attractiveness to the target fish.

[0037] like Figure 1As shown, in one embodiment, the inner wall of the counterweight channel 4 extends into a step 41, forming a limiting hole 42 at the step 41. The step 41 of the counterweight channel 4 is used to abut against the first counterweight block 2, and the counterweight ball 6 can pass through the limiting hole 42. By physically abutting against the first counterweight block 2, the step 41 can limit the maximum forward and downward displacement of the first counterweight block 2, ensuring that after resetting, the first counterweight block 2 stops at a preset balance position, such as near the center of gravity area of ​​the middle of the lure body 3 or near the front half of the lure body 3, avoiding posture imbalance caused by excessive forward tilting, such as head plunging or unnatural swimming.

[0038] The limiting hole 42 allows the counterweight ball 6 to continue moving forward and downward through the step 41, so that the position of the counterweight ball 6 can exceed the reset range of the first counterweight block 2, for example, enter the area of ​​the counterweight channel 4 closer to the head of the lure body 3. Thus, based on the first counterweight block 2 being limited, the center of gravity is slightly adjusted by the additional displacement of the counterweight ball 6, improving the naturalness of the lure's posture after it falls into the water, such as slightly raising its head or swimming horizontally.

[0039] Furthermore, the step 41 can also be designed at the front end of the weight channel 4. The "front end" of the weight channel 4 usually refers to the area near the head of the lure. Its spatial shape is limited by the overall structure of the lure (such as a streamlined shell and internal component layout), and may exhibit features such as a sloping top wall, local narrowing, or irregular curved surfaces. Since the first weight block 2 is mostly a regular shape (such as a cuboid or cylinder), it is difficult for it to completely fit with the irregular space at the front end, resulting in unused remaining space between the top wall of the front end and the first weight block 2. By using the step 41 to occupy part of the remaining space, and at the same time guiding the weight ball 6 to fill the larger remaining area between the step 41 and the first weight block 2, the "tiered utilization" of the space within the channel can be achieved.

[0040] The front end is usually not completely filled by the counterweight. In order to increase the utilization of space, a step 41 is extended from the top wall of the counterweight channel 4 to block the first counterweight 2, and the counterweight ball 6 occupies the remaining larger space.

[0041] In conventional weight transfer systems, movable counterweights constitute only a small portion of the total weight, while fixed counterweights are primarily distributed in a balanced manner. Therefore, during actual throwing, the center of gravity does not shift significantly backward, making it difficult to concentrate weight at the tail end, thus limiting the potential for improving throwing distance and accuracy. Figure 1As shown, in one embodiment, the rear end of the artificial lure body 3 is provided with a receiving space 7, and the artificial lure also includes a plurality of second counterweights 71, which are disposed in the receiving space 7. During casting, the second counterweights 71 disposed in the receiving space 7 at the rear end of the artificial lure body 3, in conjunction with the rearward movement of the first counterweight 2, make the overall center of gravity of the artificial lure closer to the tail during casting, reducing aerodynamic interference and increasing casting accuracy and casting distance.

[0042] After the main body 3 of the artificial lure falls into the water, the first counterweight 2 returns to its original position and moves forward. The counterweight at the tail of the second counterweight 71 can partially offset the forward tilting tendency of the first counterweight 2 when it returns to its original position, so that the center of gravity of the main body 3 of the artificial lure is stable in the middle or slightly rear of the middle after it falls into the water.

[0043] like Figure 1 and Figure 3 As shown, the internal space of the lure body 3 is limited by its streamlined shell (usually a slender fish or worm shape), with limited lateral width and longitudinal height. In traditional designs, the movable and fixed weights are often arranged side-by-side (movable weight in front, fixed weight in back), resulting in increased lure length or low internal space utilization, and the lure's center of gravity does not shift significantly backward during casting. In one embodiment, the rear end of the weight channel 4 extends above the receiving space 7. By placing the tail section (rear end) of the weight channel 4 vertically at the top of the receiving space 7, vertical spatial superposition is achieved, compressing the two functional areas that originally needed to be arranged front-to-back into an overlapping structure, thus achieving efficient space utilization. In addition, during casting, the first weight block 2 moves backward above the receiving space 7, resulting in a greater backward shift of the center of gravity than in traditional designs, because the movable and fixed weights in traditional designs are often arranged side-by-side.

[0044] like Figure 1 As shown, in one embodiment, a cavity 8 is formed inside the lure body 3, and the cavity 8 is located above the counterweight channel 4. This structure is simple and easy to install. Through this structural design, the density and center of gravity of the lure body 3 can be adjusted.

[0045] The cavity 8 is located above the counterweight channel 4. Since the high-density counterweight channel 4 and the first counterweight block 2 are located below, and the low-density cavity 8 is located above, the center of gravity of the lure naturally shifts downward. This low center of gravity design reduces tumbling during flight and improves trajectory stability when the lure body 3 is cast. After the lure body 3 hits the water, the low center of gravity makes it easier for the lure to maintain a horizontal posture (avoiding excessive upward or downward tilting of the head or tail), simulating the natural swimming of real fish.

[0046] like Figure 1As shown, in one embodiment, the first counterweight 2 is cylindrical, and an angle α is formed between the axis of the cylindrical first counterweight 2 and the length direction of the artificial lure body 3. The angle α is acute and greater than or equal to 3.5°. Through this structural design, the directional constraints of the counterweight's trajectory, the vector decomposition of inertial forces, and the dynamic shift of the center of gravity can be precisely controlled, thereby optimizing the mechanical response and biomimetic effect of the artificial lure throughout the entire process of casting, landing, and swimming.

[0047] like Figure 1 As shown, in this embodiment, the central axis of the cylindrical first counterweight 2 forms an angle α with the central axis of the length direction of the lure body 3, where the angle α ≥ 3.5°. The direction of the central axis of the lure body 3 is defined as follows: The line connecting two points taken at 33% and 66% of the length of the lure body 3 from its bottom surface, i.e., as shown... Figure 1 The line connecting points D and E in the diagram.

[0048] Compared to the spherical counterweight 6 (isotropic, uncontrollable direction of motion) or the square counterweight (easily jammed at sharp corners), the contact surface between the cylindrical first counterweight 2 and the counterweight channel 4 is smoother, and its axial direction can be used as the "main direction of motion", so that the sliding trajectory of the first counterweight 2 is constrained by the axial direction, avoiding disorderly shaking.

[0049] Optionally, the included angle α is greater than or equal to 3.5°. When α ≥ 3.5°, it is the "minimum effective angle" verified by fluid dynamics simulation and experiments. When α < 3.5°, the axis of the first counterweight 2 is nearly parallel to the length direction of the artificial bait body 3, and its direction of motion is almost coincident with the axis of the body, so no significant lateral or vertical inertial components can be generated; when α ≥ 3.5°, the direction of motion of the first counterweight 2 is decomposed into a "primary component" along the length direction of the body and a "secondary component" perpendicular to the axis of the body, so as to use gravity to control the center of gravity shift of the first counterweight 2.

[0050] like Figure 2 and Figure 3 As shown, in one embodiment, the artificial lure body 3 includes a front shell 31 arranged in a front-to-back direction and a rear shell 32 connecting the front shell 31. The width between the left and right sides of the front shell 31 gradually increases from front to back. The front shell 31 has a gradually widening design with a "narrower front and wider back," while the width of the rear shell gradually increases from back to front, making it similar to the body shape of a real fish. At the same time, the front and rear shells are smoothly transitioned, making its shape more streamlined, which can reduce the impact of air resistance to a certain extent.

[0051] like Figure 2As shown, in one embodiment, the openings on the left and right sides of the front shell 31 face the rear shell 32 at an angle β, where β is an acute angle and greater than or equal to 5°. That is, when viewed from above, the left and right edges of the lure body 3 fit a straight line (defined as: when viewed from above, the line connecting two points at 33% and 66% of the length along the central axis of the lure body 3, on the outermost side of the lure body 3). Figure 2 The angle β between points A and B on the same side of the main image of the lure is ≥5°, thus simulating the body shape characteristics of real fish. The gradually expanding design of the front shell 31 of the lure is a biomimetic reproduction of this natural body shape. When the angle β ≥5°, the top view of the lure has a high similarity to the body shape of real fish (such as bass).

[0052] This utility model also provides a fishing tackle, which includes a fishing rod and a lure according to any of the above embodiments. Since the lure has already been described in detail above, those skilled in the art should understand that it will not be described in detail here.

[0053] In use, the fishing rod and the lure are connected by a fishing line. The operator can tie the fishing line to the front end of the lure body 3. The lure body 3 is then cast using the fishing rod and line.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
