Description

Technical fields:

[0001] This invention relates to a fish bait, and more particularly to a lure bait that simulates the swimming motion of fish. Background technology:

[0002] Lure fishing baits are artificial baits, mainly referring to biomimetic baits used in lure fishing to attract target fish species. The main principle is that some carnivorous fish have a strong ability to hunt independently, and these fish particularly like to chase moving fish. Currently, the shape of lure fishing baits mainly imitates the shape of small fish (including shape and color), but these lure fishing baits can only achieve a straight swimming posture when pulled by the fishing line, making it difficult for many cunning carnivorous fish to take the bait.

[0003] Currently, Chinese patents have been found, such as "Invention Title: Magnetic Levitation Lure with Coil Conductor Generating Eddy Electric Field," Publication No. CN215224120U. This invention includes a shell carrying the coil conductor, a magnetic levitation traction device, and a main line. The coil conductor is mounted on the shell, and the magnetic levitation traction device is housed within the shell. The main line is connected to the main line connection point at the front end of the central axis of the magnetic levitation traction device. When the main line pulls the lure, the impedance magnetic ring and the traction magnetic ring in the magnetic levitation traction device have their magnetic poles opposite each other. Furthermore, because the rectifier at the front end of the outer shell carrying the coil conductor causes the lure to sway left and right during its forward movement, it creates a motion process with unequal forces. Under the mutual repulsion of 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 achieve left and right swaying, mimicking the swimming posture of a small fish, it uses the mutual repulsion of the magnetic fields of the magnetic ring and the traction magnetic ring to achieve this. This not only makes the structure complex and the manufacturing cost high, but also makes it susceptible to damage from predatory fish, resulting in a short service life.

[0004] Another Chinese patent, titled "Simulated Live Bait" (publication number CN204393128U), includes a body capable of simulating part of the appearance and at least part of the movement of a bait species. The body is adapted for line connection (directly or indirectly) and is mounted on, connected to, or adapted to be connected to at least one hook. It also includes an energy storage device that carries or forms part of the body or its contents, a driver connected to the energy storage device and capable of causing at least part of the movement of the body, and an initiator capable of activating the active movement of the driver and the body while simultaneously extracting energy from the energy storage device for the driver. Although this bait can completely simulate the swimming of fish, its structure is extremely complex, its manufacturing cost is high, and it is easily damaged by predatory fish, resulting in a short service life. Summary of the Invention:

[0005] The object of the present invention is to provide a lure bait for simulating fish swimming and its working method. The lure bait for simulating fish swimming has a simple structure, reasonable design, low manufacturing cost, and can simulate the swimming posture of fish.

[0006] The lure bait for simulating fish swimming according to the present invention is characterized in that: it includes a bait body made of solid material and in the shape of a shuttle. There are two upper and lower surfaces with different curvatures on the bait body, which are used to make the fluid pressures received by the upper and lower surfaces different when the bait body swims in the water body, so that the bait body presents the swimming posture of fish.

[0007] Preferably, the above-mentioned upper surface is a smooth and continuous arched curved surface.

[0008] Preferably, the above-mentioned lower surface includes a smooth and continuous first arc-shaped surface and longitudinal slots provided on both sides of the first arc-shaped surface. The longitudinal slots and the first arc-shaped surface are in arc transition, and the two longitudinal slots and the first arc-shaped surface form a "convex" shape.

[0009] Preferably, an arc-shaped sinking groove is provided at the tail end of the above-mentioned lower surface, a partition plate is provided on the arc-shaped sinking groove, the axis line of the arc-shaped sinking groove is perpendicular to the long axis direction of the bait body, and the partition plate is perpendicular to the axis line of the arc-shaped sinking groove.

[0010] Preferably, circular, special-shaped or drop-shaped sinking holes are provided on the upper and lower surfaces of the above-mentioned bait body, or on the upper surface or the lower surface.

[0011] Preferably, connecting rings are provided at the head end and the tail end of the above-mentioned bait body.

[0012] Preferably, the material of the above-mentioned bait body is a metal material, plastic or wood. The bait body is integrally formed or made by mechanical cutting; or there are multiple different materials in the bait body at the same time.

[0013] Preferably, the above-mentioned upper and lower surfaces are smooth surfaces that can reflect light.

[0014] Preferably, the above-mentioned bait body is 50 - 400 mm in length, 10 - 80 mm in width, 5 - 40 mm in thickness, and the thickness of the partition plate is 0.5 - 4 mm.

[0015] The working method of the lure bait for simulating fish swimming according to the present invention is characterized in that: the lure bait for simulating fish swimming includes a bait body in the shape of a shuttle. There are two upper and lower surfaces with different curvatures on the bait body. One end in the long axis direction of the bait body is connected to a fishing line, and the other end in the long axis direction of the bait body is connected to a fishhook or not. When the fishing line is reeled in, let out or the fishing rod is lifted by the fishing reel, the fluid pressures received by the upper and lower surfaces are different when the bait body swims in the water body, so that the bait body presents the swimming posture of fish and generates turbulent flow to attract fish to come for baiting.

[0016] The lure of this invention, which simulates fish swimming, is made of solid material, making it sturdy and durable, not easily damaged by predatory fish, and with a long service life. In addition, due to the presence of two upper and lower curved surfaces with different curvatures, as well as the sinker and baffle, the upper and lower curved surfaces, as well as the sinker and baffle, experience different fluid pressures when the lure swims in the water, making it easier for predatory fish to take the bait.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. Attached image description:

[0023] Figure 15 yes Figure 14 Cross-sectional view of the middle section (including some dimensional parameters). Detailed implementation method:

[0024] This invention provides a lure for simulating fish swimming, comprising a spindle-shaped lure body 1 made of solid material. The lure body 1 has two upper curved surfaces 101 and lower curved surfaces 102 with different curvatures, so that the upper and lower curved surfaces experience different fluid pressures when the lure swims in water, allowing the lure to mimic the swimming posture of a fish. The lure body 1 being made of solid material does not mean that the lure body 1 is completely solid; it may have holes or cavities inside. The solid material may be made of metal materials such as lead, zinc, tin, and stainless steel, or plastic or wood. The lure body may be integrally molded or machined, or the connecting ring may be cast into the lure body and then integrally molded, or machined; or the lure body may contain multiple different materials.

[0025] The shuttle shape refers to a shape that is thick and wide in the middle and narrow and thin at both ends; the upper curved surface 101 and the lower curved surface 102 have different curvatures respectively (curvature is a quantity that describes the degree of bending of a geometric body, for example, the degree to which a curved surface deviates from a plane, or the degree to which a curve deviates from a straight line). In the above structural situation, the bait body 1 of the present application can present the swimming posture of fish.

[0026] In order to better simulate various swimming postures of fish, specifically, the upper curved surface 101 is a smooth and continuous arched curved surface; the above-mentioned lower curved surface 102 includes a smooth and continuous first arc-shaped curved surface 103 and longitudinal slots 104 provided on both sides of the first arc-shaped curved surface. The longitudinal slots and the first arc-shaped curved surface are in arc transition. The two longitudinal slots and the first arc-shaped curved surface form a "convex" shape, and the fold angle of the longitudinal slot 104 is also in arc transition; the two longitudinal slots 104 are symmetrically arranged.

[0027] More preferably, an arc-shaped sink 105 is provided at the tail end of the above-mentioned lower curved surface 102. A partition plate 106 is provided in the middle of the arc-shaped sink. The axis line of the arc-shaped sink is perpendicular to the long axis direction of the bait body. The partition plate 106 is perpendicular to the axis line of the arc-shaped sink 105. The two parts formed after the arc-shaped sink 105 is separated by the partition plate 106 are symmetrically arranged.

[0028] A hydrodynamic analysis was performed on the bait of the present invention under the above structure, as Figure 3-10 shown: The lure bait for simulating fish swimming in the present invention uses two upper curved surfaces 101 and lower curved surfaces 102 with different curvatures (that is, the upper curved surface 101 and the lower curved surface 102 are two asymmetric surfaces, and the fluid pressures received by the upper curved surface and the lower curved surface are different when swimming in the water body), which can play special and different roles during the fishing operation: During a typical line retrieval process, under the impact of the oncoming flow directly in front of the head, the pressure on the abdomen (lower curved surface 102) of the bait of the present application is significantly higher than the pressure on the back (upper curved surface 101) in most areas. This pressure difference gives the bait body of the present application a tendency to move towards the back, and is coupled with the high-pressure area at the tail arc-shaped sink 105 part, giving the tail of the bait body of the present application an upward lifting moment. At the same time, the longitudinal slots 104 on both sides of the bait body of the present application cooperate with the arc-shaped sink 105 and the partition plate 106 to form an eddy current system. The high-speed water flow impact guided by the longitudinal slots 104 on both sides also increases the pressure difference between the upper and lower sides of the bait body to a certain extent (as Figure 3-8 shown).

[0029] When the incoming current velocity is suitable, the bait of this application will form an arc-shaped swimming posture due to the coupling of inertia and the upward torque of the tail. Compared with the straight up and down of existing ordinary fish baits, the arc-shaped swimming of the bait of this application is more in line with the swimming characteristics of fish. In addition, the fluid characteristics of different parts of the water are not completely consistent, and during the fishing process, the initial state of the lure (speed, position, angle of attack relative to the incoming current (direction of lure movement and direction of water movement)) is different, presenting a more realistic arc-shaped swimming, making the swimming of the bait more like a fish. This will reduce the wariness of cunning predatory fish (fish that can easily see the straight up and down movement of existing fish baits). At the same time, the inconsistent velocity on both sides of the upper and lower flow fields at the rear of the bait of this application generates eddies along the axial direction, leaving eddy disturbances in the water. Combined with the eddies that fall off the jig after the jig moves, this can stimulate the sensory organs of fish (lateral line, etc.), attracting fish to hunt.

[0030] During a typical descent (45° from the incoming flow direction), the vortex generated by the arc-shaped sinker 105 at the tail of the bait body induces a low-pressure zone on the back (upper curved surface 101), which slows down the descent speed of the bait body. Furthermore, this vortex couples with the vortex generated by the longitudinal slots 104 on the side, thus promoting the formation of the overall vortex. This design makes the lure's movement less of a simple up-and-down motion and more akin to a slow, drifting descent. Furthermore, because the fluid characteristics of different parts of the water are not entirely uniform, and because the initial state of the lure (speed, position, angle of attack relative to the incoming current) varies during fishing, eddies are constantly generated in the eddy zone, causing the lure to detach. This results in the lure exhibiting an irregular trembling / rotating descent. Compared to the descent action of existing ordinary fish baits, the trembling and rotation of this lure create eddies and reflections in the water that resemble a dying fish, making it more attractive to cunning fish. The baffle plate 106 on the curved sinker 105 at the tail adjusts the frequency and amplitude of the trembling and rotation, and enhances the strength of the lure (e.g., Figure 9-10 (As shown).

[0031] On the upper and lower curved surfaces of the above-mentioned bait, or on the upper or lower curved surfaces, there are sinkers 2 in the shape of circles, irregular shapes, or teardrops. The sinkers 2 can also be through holes. The sinkers are used to install fish eye stickers or fish eye models. The head and tail ends of the above-mentioned bait are provided with connecting rings 3. The sinkers 2 or through holes are not necessary. The connecting rings 3 are used to connect fish hooks, fishing lines, etc., but they are also not necessary. The connecting rings 3 can be replaced by small holes at the head and tail ends of the bait to connect fish hooks or fishing lines.

[0032] The connecting ring 3 of this lure can be used to connect accessories such as hooks, lines, and swivels. It can be used in various ways, such as: vertically lowering it on a boat and coordinating it with the reel's retrieval, line release, rod lifting, and rod lowering actions to create various swimming motions, generating turbulence and reflection (or luminescence) (this can be achieved by polishing the upper and lower curved surfaces smooth (or applying reflective stickers or luminescent paint)), thus attracting fish to bite; or casting the lure a distance and coordinating it with the reel's retrieval, line release, rod lifting, rod lowering, and rod jerking actions to create various swimming motions, generating turbulence and reflection (or luminescence), thus attracting fish to bite.

[0033] The dimensions of the bait are as follows: length 50-400 mm, width 10-80 mm, thickness 5-40 mm; partition plate thickness 0.5-4 mm. A specific embodiment has the following parameters: excluding the connecting ring, length 127 mm, maximum width 32.08 mm, maximum thickness 14 mm, partition plate thickness 2 mm. The bait's main viewing direction (e.g., ...) Figure 13 The upper curved surface is an arc with a radius of 350 mm. The first arc-shaped curved surface 103 is an arc with a radius of 350 mm. The arc-shaped sinking groove 105 is composed of two arc segments with radii of 22 mm and 60 mm respectively. The upward viewing direction of the bait (e.g.) Figure 14 The two sides are composed of three arcs of other dimensions, with radii of 165 mm, 175 mm, and 12 mm respectively. (See the bottom view of the bait's mid-section). Figure 15 The radius of the upper curved surface is 22 mm, the radius of the first arc surface 103 is 42 mm, and the radius of the corner arc of the longitudinal slot 104 is 4 mm; the size parameters and surface parameters of the bait in this application are not limited to the values ​​disclosed above.

[0034] The lure of this invention, which simulates the movement of fish, is made of solid material, making it sturdy and durable. It is not easily damaged by predatory fish and has a long service life. In addition, because the lure has two curved surfaces with different curvatures, the upper and lower curved surfaces are subjected to different fluid pressures when the lure moves in the water, making the lure resemble the swimming posture of a fish and making it easier for predatory fish to take the bait.

[0035] The above description is merely an embodiment of the present invention. Any equivalent changes or modifications made within the scope of the claims of the present invention shall be covered by the present invention.
