Description

Lure bait simulating fish movement and working method thereof Technical Field

[0001] The invention relates to a fishing bait, in particular to a lure fishing bait which simulates the swimming of fish. Background Art

[0002] Lure baits are artificial baits, primarily bionic baits used to attract target fish in lure fishing. The principle is that some carnivorous fish have strong autonomous hunting abilities and are particularly fond of chasing dynamic fish. Currently, lure baits primarily mimic the appearance of small fish (including shape and color). However, these lures can only swim in a straight line when pulled by the fishing line, making it difficult for many cunning carnivorous fish to take the bait.

[0003] Currently, Chinese patents have been retrieved, such as "Invention Name: Magnetic Levitation Lure Fishing Bait with Coil Conductor Generating Vortex Electric Field", Publication No. CN215224120U, which includes a housing for carrying coil conductor, a magnetic levitation traction device and a main line. The coil conductor is arranged on the housing for carrying coil conductor, the magnetic levitation traction device is arranged inside the housing for carrying coil conductor, and the main line is connected to the main line connection point at the front end of the central axis in the magnetic levitation traction device. When the main line is pulled to pull the lure to move, since the impedance magnetic ring and the traction magnetic ring in the magnetic levitation traction device have the same magnetic poles arranged opposite to each other, In addition, because the rectifier device at the front end of the shell carrying the coil conductor causes the lure to swing left and right during the forward movement, it produces a movement process with unequal forces. Under the action of the mutual repulsion between the magnetic fields of the impedance magnetic ring and the traction magnetic ring, the coil conductor continuously cuts the moving magnetic lines of force, generating an eddy electric field. Although the lure can swing left and right and imitate the swimming posture of a smaller fish, it uses the mutual repulsion between the magnetic fields of the magnetic ring and the traction magnetic ring to achieve this. Not only is the structure complex and the production cost high, but it is also easily damaged by attacks from carnivorous fish, resulting in a short service life.

[0004] In addition, the Chinese patent "Invention Name: Simulated Live Bait", publication number N204393128U, includes a main body, which can simulate part of the appearance and at least part of the movement of the bait species, the main body is adapted to be connected to a line (directly or indirectly), and is mounted on or connected to or suitable for being connected to at least one fishing hook, an energy storage device, which carries or forms a part of the main body or the contents of the main body through the main body or the contents of the main body, a driver, which is connected to the energy storage device and can cause at least part of the movement of the main body, and a starter, which can start the active movement of the driver and the body, and at the same time extract energy for the driver from the energy storage device. Although the bait can fully simulate the swimming of fish, its structure is extremely complex and the production cost is very high. It is easily damaged by attacks by carnivorous fish, resulting in a short service life. Technical issues

[0023] The present invention discloses a lure for simulating the movement of fish, including a shuttle-shaped lure body 1 made of a solid material. The lure body 1 has an upper curved surface 101 and a lower curved surface 102 of different curvatures, so that the upper and lower curved surfaces are subjected to different fluid pressures when the lure body swims in water, allowing the lure body to resemble the swimming posture of a fish. The fact that the lure body 1 is made of a solid material does not mean that the lure body 1 is completely solid. The lure body 1 may have holes or cavities inside. The solid material may be made of metal materials such as lead, zinc, tin, stainless steel, or plastic or wood. The lure body may be integrally molded or manufactured by mechanical cutting, or a connecting ring may be melt-cast into the lure body and then integrally molded or manufactured by mechanical cutting. Alternatively, the lure body may be made of multiple different materials.

[0024] The shuttle shape refers to a shape that is wide and thick in the middle and narrow and thin at both ends; the upper curved surface 101 and the lower curved surface 102 have different curvatures (curvature is a quantity that describes the degree of bending of a geometric body, such as the degree to which a curved surface deviates from a plane, or the degree to which a curve deviates from a straight line). Under the above structural conditions, the bait body 1 of the present application can present the swimming posture of a fish.

[0025] In order to better simulate the various swimming postures of fish, the specific upper curved surface 101 is a smooth, continuous arched curved surface; the above-mentioned lower curved surface 102 includes a smooth, continuous first curved surface 103 and longitudinal grooves 104 arranged on both sides of the first curved surface, and the longitudinal grooves and the first curved surface are circular arc transitions. The two longitudinal grooves and the first curved surface form a "convex" shape, and the corners of the longitudinal grooves 104 are also circular arc transitions; the two longitudinal grooves 104 are symmetrically arranged.

[0026] More preferably, an arc-shaped groove 105 is provided at the tail end of the above-mentioned lower curved surface 102, and a partition plate 106 is provided in the center of the arc-shaped groove. The axis of the arc-shaped groove is perpendicular to the long axis direction of the bait body, and the partition plate 106 is perpendicular to the axis of the arc-shaped groove 105. The two parts formed by the arc-shaped groove 105 being separated by the partition plate 106 are symmetrically arranged.

[0027] A fluid dynamics analysis of the above-mentioned structure of the fishing lure of the present invention is performed, as shown in Figure 3-10:

[0028] The present invention's lure, which simulates fish movement, utilizes two asymmetrical upper and lower surfaces 101 and 102 with different curvatures (i.e., the upper and lower surfaces 101 and 102 are asymmetrical and are subjected to different fluid pressures when swimming in water). This allows for a unique and effective fishing operation: During a typical reel-in, under the impact of the incoming flow directly in front of the head, the pressure on the belly (lower surface 102) of the lure is significantly higher than the pressure on the back (upper surface 101) in most areas. This pressure differential creates a tendency for the lure to move dorsally, and coupled with the high-pressure region at the tail arc-shaped sink 105, this creates an upward-lifting torque at the tail of the lure. At the same time, the longitudinal grooves 104 on both sides of the bait body of the present application cooperate with the arc-shaped sinking grooves 105 and the partition plates 106 to form a vortex system. The high-speed water flow impact guided by the longitudinal grooves 104 on both sides also increases the pressure difference between the upper and lower sides of the bait body to a certain extent (as shown in Figures 3-8).

[0029] When the incoming flow velocity is appropriate, the lure of the present invention will form an arc-shaped swimming posture due to the coupling of inertia and the torque of the tail lifting upward. Compared with the straight up and down movement of existing common fishing lures, the arc-shaped swimming posture of the lure of the present invention is more consistent with the swimming characteristics of fish. In addition, the fluid characteristics in different parts of the water body are not completely consistent. Moreover, during fishing, the initial state of the lure (speed, position, angle of attack relative to the incoming flow (lure movement direction and water flow direction)) varies, resulting in a more realistic arc-shaped swimming posture, making the lure's swimming more like fish, which can lower the vigilance of cunning predatory fish (fish that can easily detect the straight up and down movement of existing lures). At the same time, the inconsistent speed of the upper and lower sides of the rear of the lure of the present invention generates vortices along the axis, leaving a disturbance in the water. Combined with the vortices that fall off the iron plate after the iron plate moves, they can stimulate the fish's sensory organs (such as the lateral line), attracting fish to come and feed.

[0030] During a typical descent (at a 45° angle from the incoming flow direction), the vortex generated by the arc-shaped groove 105 at the tail of the bait induces a low-pressure area on the back (upper curved surface 101), which slows down the bait's descent speed. This, coupled with the vortex generated by the longitudinal grooves 104 on the side, promotes the formation of the overall vortex. The bait does not simply move up and down, but rather moves closer to a slowly falling state. At the same time, since the fluid characteristics in different parts of the water body are not completely consistent, and the initial state of the lure (speed, position, and angle of attack relative to the incoming flow) is different during fishing, vortices formed in the vortex area will continuously be generated and shed, causing the lure of the present application to exhibit an irregular vibration / rotation while falling. Compared with the falling action of existing ordinary fishing lures, the vortices and reflections generated in the water by the vibration and rotation of the lure of the present application are more like a dying fish, which is more attractive to cunning fish. The partition plate 106 on the arc-shaped sink 105 at the tail plays a role in adjusting the vibration and rotation frequency and amplitude, and enhancing the strength of the fishing lure (as shown in Figures 9-10).

[0031] On the upper curved surface and the lower curved surface of the above-mentioned bait body, or on the upper curved surface or the lower curved surface, there is a countersunk hole 2 in a circular, irregular or teardrop-shaped shape. The countersunk hole 2 can also be a through hole. The countersunk hole is used to install a fisheye sticker or a fisheye model; the head end and the tail end of the above-mentioned bait body are provided with a connecting ring 3, and the countersunk hole 2 or the through hole is optional; the connecting ring 3 is used to connect fish hooks, fishing lines, etc., but it can also be optional. The fish hook or fishing line can be connected by replacing the connecting ring 3 with fine holes provided at the head end and the tail end of the bait body.

[0032] The connecting ring 3 of the lure can be used to connect accessories such as fish hooks, fishing lines, and split rings. During use, the lure can be used in a variety of ways, for example: vertically lowered on a boat, and coordinated with the fishing reel reeling action, the fishing reel line release action, the fishing rod lifting action, and the fishing rod lowering action, so that the lure can exhibit various swimming postures, generate turbulence and reflect light (or glow) (the reflection (or glow) can be achieved by grinding the upper and lower curved surfaces into smooth surfaces (or affixing reflective stickers or spraying luminous paint)), thereby attracting fish to take the bait; the lure can also be thrown far away, and coordinated with the fishing reel line reeling action, the fishing reel line release action, the fishing rod lifting action, the fishing rod releasing action, and the fishing rod twitching action, so that the lure can exhibit various swimming postures, generate turbulence and reflect light (or glow), thereby attracting fish to take the bait.

[0033] The dimensional parameters of the lure body are as follows: the lure body is 50-400 mm long, 10-80 mm wide, and 5-40 mm thick, and the thickness of the partition sheet is 0.5-4 mm. The parameters of a specific embodiment are: the length excluding the connecting ring is 127 mm, the widest part is 32.08 mm, the thickest part is 14 mm, and the thickness of the partition sheet is 2 mm. In the main viewing direction of the lure body (as shown in Figure 13), the upper curved surface is an arc with a radius of 350 mm. The first curved surface 103 is an arc with a radius of 350 mm. The arc-shaped sink 105 is composed of two arc segments with radii of 22 mm and 60 mm respectively. In the bottom viewing direction of the lure body (as shown in Figure 14), the two sides are composed of three arc segments of other sizes, with radii of 165 mm, 175 mm, and 12 mm respectively. In the bottom view of the middle section of the lure body (as shown in Figure 15), the radius of the upper curved surface arc is 22 mm, the arc radius of the first curved surface 103 is 42 mm, and the corner arc radius of the longitudinal slot 104 is 4 mm; the size parameters and surface curvature parameters of the bait body of the present application are not limited to the above disclosed values.

[0034] The lure bait for simulating fish swimming of the present invention is strong and durable because the bait body is made of solid material, and is not easily damaged by attacks from carnivorous fish, and has a long service life. In addition, because the bait body has two upper and lower curved surfaces with different curvatures, the upper and lower curved surfaces are subjected to different fluid pressures when the bait body swims in water, allowing the bait body to present the swimming posture of fish, making it easier for carnivorous fish to be hooked.

[0035] The above descriptions are merely embodiments of the present invention. Any equivalent changes or modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
