Abstract

This float for long-distance cage fishing offers high buoyancy while allowing the use of small weighted cages and long-distance casting of the entire rig, including the cage. It also provides both static and dynamic visibility after hitting the water, while simultaneously attracting fish and increasing the chances of hooking. This float combines diverse functions and unique features to accommodate various conditions. [Solution] A long-distance casting float 1 equipped with a large wing 4, a large teardrop-shaped float 2, and a weight 5, whose flight is enhanced by the excellent hydrodynamic features in which each component synergistically enhances many flight performance aspects, such as straight-line stability and horizontal attitude assurance by the weight and large tail wing, cruising stability by the teardrop-shaped float wing, and gliding effect by the horizontal tail wing that catches the airflow, thereby improving the long-distance casting performance of the entire rig. After landing on the water, the large buoyancy and uprightness of the bottom of the float wing allow it to float baskets of various weights, improving static and dynamic visibility, fish attraction effect and hook-up opportunities, and providing a long-distance casting float in which each component, the wing, float wing, and weight, can be replaced according to the conditions.

Description

[Technical Field]

[0001] This invention relates to a float used in long-distance casting cage fishing. [Background technology]

[0002] Generally, long-distance cage fishing, which is done from rocky shores or breakwaters, uses fishing gear consisting of a long-distance casting rod with a reel, main line, float, and long-distance cage rig (long-distance cage, spreader, cushion rubber, leader (line attached to the hook), bait hook, chum bait, bait, etc.). The rig is cast several tens to over a hundred meters away from the rocky shore or breakwater, and then the cage rig is sunk to the desired depth. The chum bait is then released from the cage in sync with the bait attached to the hook to catch fish.

[0003] A typical long-distance casting cage rig will be explained based on the diagram shown in Figure 13b. However, the float shown here is not the typical short float 1' (Figure 16b), but rather an example of the medium-length float 1 of the present invention. Incidentally, the only difference between the long-distance casting cage rig using the typical short float 1' and the medium-length float 1 of the present invention is the difference in the distance between the float stopper rubber 11 and the long-distance casting cage rig 14, based on the difference in the length of the float, and does not affect the essence of the present invention in any way.

[0004] The long-distance casting cage rig 14 is tied to the main line 10 wound on the reel. A float stopper rubber 11 is located between the cage rig 14 and the float 1. This is necessary to prevent contact between the float 1 and the cage rig 14 when casting or retrieving. The distance between this float stopper rubber 11 and the cage rig 14 is determined by the length (shaku) of the float 1; therefore, the distance will be shorter for shorter floats and longer for longer floats. A sinker bead 12 is located between the reel and the float 1, which is to prevent the foot 6 of the float 1 from contacting the rod guide. A float stopper cord 13 is located between the reel and the sinker bead 12. This float stopper cord 13 is tied to the main line 10 to adjust the cage rig 14 to the desired depth (called the shelf). Therefore, when the cage rig 14 begins to sink into the sea, the main line 10 sinks up to the point where it is tied to the float stopper cord 13. To stop the basket rig 14 where it is tied with the float stopper string 13, a stopper bead 12 is needed to catch on the float stopper string 13. Thus, the stopper bead 12 is used not only to prevent the float foot 6 from coming into contact with the rod guide, but also to prevent the basket rig 14 from sinking at the stopper bead 12. Generally, the float foot 6 is not passed directly through the main line, but a swivel with a snap is inserted in between. This makes it easier to remove the float 1 when replacing it or when it gets tangled with someone else's rig.

[0005] Incidentally, for casting over 100m, 6-pound nylon line is generally used as the main line. Although this line has the drawback of being heavy (approximately 13g per 100m), it has the advantage of being strong enough for long casts and easy to untangle. On the other hand, some anglers use PE (polyethylene) line, which is lighter, thinner, and stronger than nylon line, but it is difficult to untangle when it gets tangled, and can cause trouble for others by getting tangled with other people's lines, so it is generally not used in crowded fishing spots.

[0006] Describe general tools used for long-distance casting with a casting distance of over 100 m. For the rod, use a rod of size 3 to 5 dedicated to long-distance cage fishing (sinker load of about 8 to 20, 5 m to 6 m). For the reel, use a spinning reel or a twin-spool reel that can wind about 200 m of 6-strand nylon thread. However, a twin-spool reel, which is less likely to have the main line get tangled, is more suitable for long-distance casting. For the cage, use one of about size 12 to 20. A cage lighter than that is generally called a light cage.

[0007] Generally used float 1' for long-distance cage fishing has been required to be light, have buoyancy, be visible, etc. For the floating body (main body) 2, in order to have the buoyancy necessary to float on the water surface while receiving the gravity of the cage rigging 14, a floating body shape with a large bulk has inevitably been adopted (Fig. 23b). Also, regarding its shape, a spindle shape (see, for example, Patent Documents 1 and 2), a cylindrical shape with hemispherical ends, a cylindrical shape with conical ends at both ends (see, for example, Patent Document 3), a shape where the bottom of the droplet is arranged on the wing side (Fig. 23c), etc. are common. However, in any of these shapes, no design has been made from the perspective of fluid dynamics, so the magnitude of air resistance has been an issue.

[0008] On the other hand, the droplet shape has already been generalized in long-distance cages. As shown in Fig. 29, for long-distance cages for cage rigging, for example, a cylindrical shape with conical ends at both ends (a), a spindle shape (b), a droplet shape (c), etc. have been conventionally used. Thus, although the droplet shape has a track record in long-distance cages, it has not been conventionally used for floats.

[0009] [[ID=Therefore, when casting the basket device 14 over a long distance, if the target shelf is deep, the distance between the basket device 14 and the float 1' becomes long. During flight, the float 1' is subject to air resistance and moves away from the basket device 14 (Fig. 16b). Therefore, the basket device 14 can be cast over a certain distance (Fig. 17b, Fig. 19a). However, due to the strong air resistance acting on the float 1', its flight is braked, and the float 1' separates from the basket device 14 and lands considerably in front (Fig. 19b). The basket device 14 that enters the water sinks with the float 1' floating on the water surface as a fulcrum. As a result, the basket device 14 is pulled back to the landing point of the float 1' (Fig. 19c, Fig. 21b). That is, when the shelf is deep, the landing point of the float 1' becomes the point of the basket device.

[0010] On the other hand, when the target shelf is shallow, the distance between the basket device and the float 1' becomes short (Fig. 16c). Due to air resistance, the flight of the float 1' is braked, which has been interfering with the flight of the basket device 14 as a result (Fig. 17c, Fig. 20, Fig. 21c). To reduce the impact of this braking, there was no other way but to use a No. 20 basket and rely on arm strength and the repulsive force of the rod to cast over a long distance. Due to these reasons, it was difficult to obtain the effect of casting the basket device over a long distance.

[0011] As one means to solve this problem, a device was devised to attach a weight 5 to the bottom of the spindle-shaped buoyancy body 4 (see Patent Document 1). If this buoyancy body 4 is used for long-distance casting basket fishing, since the buoyancy body 4 flies independently, it is possible to avoid interfering with the flight of the basket device as described above and being pulled back in front after the basket lands in the water. However, since this buoyancy body has no wings, its flight attitude is likely to be unstable. Therefore, it is difficult to cast it together with the basket device as required by the present invention, and the visibility after landing is also low.

[0012] Similarly, while Patent Document 2 describes it as spindle-shaped, it depicts a form closer to a teardrop shape. Specifically, this float 10 has two cone-shaped apexes at both ends, and the apex angle of the base is large, but it does not have a streamlined shape with a bulge. Moreover, in this form, weights are attached to the upper and lower ends of the float body to lay it on the water surface and wait for a fish to pull, and it does not have the wings necessary for a long-distance casting cage. Therefore, even if one attempts to cast it a long distance, flight performance cannot be expected, and it becomes difficult to ensure the visibility (visual sight) of the float 10. In addition, with a long-distance casting rig, there is a risk of missing the opportunity for the float 10 to be temporarily visible when a fish pulls on it.

[0013] Furthermore, Patent Document 3 describes a similar embodiment to a float for long-distance cage fishing. In this embodiment, the float is cylindrical with conical ends, a weight is attached to the bottom of the lower end, and a foot and propeller-type rotor are attached to the upper end. This weight is heavy enough to serve both the purpose of long-distance casting and self-supporting on the water surface. When this buoyancy body 1 is used for long-distance cage fishing, the foot must be moved to the weight side, and the buoyancy of the buoyancy body must support the weight of both the weight fixed to the buoyancy body 1 and the weight of the cage. As a result, it is expected that the position of the rotor after landing on the water will be just above the water surface or submerged, making it impossible to ensure the visibility of the buoyancy body during long-distance casting.

[0014] Some floats used in long-distance cage fishing are long and have extra-large wings 4 designed to improve visibility (Figure 23c). As for the shape of the float body 2, we have manufactured various types, such as a teardrop shape with the base facing the wings, and a cylindrical shape with a hemisphere at the base. Among these, the float that proved to be the most user-friendly (Figures 28e~f) has a total length of 57cm, with each wing (trapezoidal) measuring 11cm on the long side, 4.5cm on the short side, and 6.5cm at its widest point. In the case of this float 1", the long length increases the distance from the ground to the tip of the rod when casting, so even when using a long rod, the range of motion for swinging the rod is narrowed, making it difficult to cast long distances (Figure 14b).

[0015] Generally, the 1' float used in long-distance cage fishing has a narrow buoyancy range, so it was necessary to match the size of the float to the cage size. Therefore, when casting was difficult due to strong winds, or when fishing at deeper depths, if the cage size was increased, the size of the 1' float also had to be changed accordingly. In addition, the buoyancy of the 1' float decreases with prolonged use. As a result, the 1' float often became unusable with the cage size that had been used previously due to deterioration over time. Furthermore, the appearance of the 1' float changes in various ways depending on the weather, sunlight, and time of day at the fishing spot. Due to these circumstances, long-distance cage fishing required having a wide variety of 1' floats to suit various situations, which resulted in the inconvenience of the entire equipment becoming bulky. [Prior art documents] [Patent Documents]

[0016] [Patent Document 1] Publication No. 50-24694 [Patent Document 2] Publication No. 55-017483 [Patent Document 3] Official Gazette No. 3203436 [Overview of the Initiative] [Problems that the invention aims to solve]

[0017] To cast the cage rig 14 a long distance, it is important to swing the rod widely. For this reason, most floats 1' used for long-distance cage fishing, whether commercially available or handmade, are about 20-30 cm in length (Figure 23b). This length allows for a wide swing of the rod.

[0018] However, the float 1' used in the long-distance casting cage rig 14 must float on the water surface while supporting the weight of the cage rig 14, so it needs to have a certain amount of buoyancy. For this reason, the float body 2 is often light and thick (Figure 23b). Generally, the size of the sinker used in the long-distance casting cage rig 14 ranges from No. 12 (approximately 45g: No. 12 x 3.75g / No.) to No. 20 (approximately 75g), and the wing 4 of the float 1' is designed to float a few centimeters above the water surface (Figure 23b). Incidentally, when casting a No. 12 cage rig, the total weight is around 100g. This is because, in addition to the float 1', balance, and cushion rubber, the cage 15 (Figure 29) contains chum bait and hook bait. In the water, the chum bait is scattered, and the buoyancy of the float inside the cage is also added, resulting in a weight of approximately 75g. The volume of the floating object that sinks under this load is approximately 75 cm³. 3 Therefore, the weight can be estimated to be around size 20. Thus, the size of the float 1' that floats a size 12 cage rig 14, that is, the size of the float 1', is approximately 12, and taking into account the decrease in buoyancy due to aging, the volume of the float 2 is approximately 100-125 cm³. 3 (Floating body: cylindrical shape with a diameter of 11cm to 13cm x radius of 1.5cm, 4 / 3·πr) 2 L = 103.6~122.5 cm 3 Approximately 150-180cm for size 20. 3 The degree is typical (floating body: cylindrical shape with a diameter of 12cm to 14cm x radius of 1.75cm, 4 / 3πr 2 L = 153.9~179.5cm 3 ).

[0019] When the basket rig 14 is cast using these float configurations 1′, ideal long-distance casting is not possible regardless of the depth of the rig, as mentioned above (Figures 16b-c, 17b-c, 19, 20, and 21b-c). On the other hand, casting is difficult with a long float 1″ of about 60cm (Figure 14b). However, the extra-large wing 4 provides a stable upright posture, resulting in high static visibility, as shown in the configurations in Figures 24c, 27(i)c, and (ii)c. However, because the distance from the water surface to the foot 6 is long, it is difficult to induce an uprighting motion (Figure 27(iii)c).

[0020] Furthermore, in long-distance cage fishing, the float size 1' needs to match the size of the cage, and it's necessary to address deterioration over time. In addition, it was necessary to prepare many types of floats 1' in various colors, sizes, and with lights to accommodate various conditions. [Means for solving the problem]

[0021] To cast a cage rig a long distance, it is necessary to swing the rod as widely as possible during the cast, and to ensure that the float does not touch the main line and does not hinder the flight of the cage rig as much as possible. First, to solve the former problem, it is necessary not to make the length of the float too long. However, if it is too short, visibility will decrease when casting long distances, so one of the features of the float of this invention is that the length of the float is medium as a means of solving this problem. Furthermore, to solve the latter problem, it concerns how to extend the flight distance while suppressing the deceleration after the cast cage rig has reached its maximum speed. Here, we propose three means that take fluid dynamics into consideration to suppress the deceleration of the casting speed as much as possible.

[0022] First, one method is to fix a weight to part or all of the section between the float (main body) and the foot. This not only shifts the center of gravity of the float forward, but also increases the inertial force for flight due to the weight's gravitational effect. In addition, in the case of floats used for long-distance cage fishing, the three or four biplane wings also act as tail fins during flight. The horizontal tail function of these wings, combined with the forward center of gravity due to the weight, helps maintain a horizontal attitude, and the inertial force of the weight and the vertical tail function also improve the straight-line flight.

[0023] The second method involves making the shape of the float (main body) teardrop-shaped, or close to teardrop-shaped. This method reduces air resistance and improves flight performance through lift. The reason air resistance is reduced is that, from a fluid dynamics perspective, the teardrop shape, which has the least drag, is used as the float. The reason flight performance is improved through lift is due to the angle of the airflow received in front of the teardrop-shaped float as the cage rig flies in a parabolic trajectory. When this airflow hits the bulge at the bottom of the float, this airflow acts as an angle of attack that gives lift to the teardrop shape. Therefore, lift continues to act on the float during flight.

[0024] The third method is the adoption of large biplane wings. By using three or four large wings, the horizontal stabilizer catches the airflow from below, thereby providing gliding performance.

[0025] To improve the visibility of a float that has landed far away, it is effective to achieve both static and dynamic visibility. First, regarding the means of improving static visibility, it is very effective not only to equip the float with large wings, but also to raise the entire float as much as possible above the water surface. To achieve this, it is necessary not only to increase the volume of the float body within the limited float length range, but also to make the depth to which the float body sinks above the water surface as shallow as possible and raise the position of the center of buoyancy (center of buoyancy). The most suitable shape for a float body that satisfies these requirements is a teardrop shape, and all that is needed is to make the bottom of the teardrop body submerged in water. With a teardrop-shaped float body, the volume of the bottom of the teardrop body is large, so the depth to which the float body sinks above the water surface can be effectively reduced. In addition, the range of load of the weight of the cage rig can be greatly expanded compared to existing floats. If this teardrop-shaped float body is used as a float, both the large wings and the float body will rise high above the water surface, resulting in the advantage of improved static visibility of the float even from a distance.

[0026] On the other hand, to improve dynamic visibility, one can utilize the way the float rises high above the water surface and allow it to right itself in the presence of waves or crosswinds. To achieve this, the unique characteristics of the teardrop-shaped float should be utilized so that the float's center of buoyancy is as close to the water surface as possible, allowing it to return to its original upright position when it falls over due to its restorative force. This enables the float to right itself in the presence of waves or crosswinds, creating a new feature that enhances its dynamic visibility even from a distance. However, some anglers enjoy fishing without constantly watching the float by using reels equipped with a line alarm function that signals when a fish is hooked. This type of fishing requires caution in crowded fishing spots, as it can lead to entanglement with surrounding fishing gear.

[0027] Conventional floats for long-distance cage fishing have been thick and short for the reasons mentioned above. As a result, they only retain enough buoyancy on the water surface for the wings to be visible, and therefore do not perform an uprighting motion while waiting for a bite. On the other hand, the float of the present invention is designed to perform an uprighting motion, so the cage rig moves up and down in sync with the uprighting motion of the float. This movement is transmitted via the leader to the hook, which is being carried by the current along with the chum released from the cage. As a result, the float of the present invention has the characteristic of having an attractive effect that draws in surrounding fish by causing the bait attached to the hook to move in a repetitive motion.

[0028] Furthermore, with typical long-distance casting rigs, anglers have to wait until a fish takes the hook. Therefore, it is difficult to time the hookset with the float's pull, as is possible with other fishing methods. This often resulted in poor hooksets. In contrast, the float of this invention has sufficient buoyancy to float on the surface of the seawater, so when a fish pulls, the hook can be firmly set in the fish's mouth.

[0029] Conventional floats for long-distance cage fishing had a narrow buoyancy range, requiring the use of the same size float and cage. Therefore, when changing the cage size depending on factors such as wind conditions or fishing depth, the float also had to be changed to one of the same size. Furthermore, since visibility varied depending on the conditions, multiple colors of fins were necessary. Consequently, long-distance cage fishing required preparing several large floats.

[0030] To address these challenges, the float of the present invention, with its large float body and teardrop shape, not only allows for a wide range of basket sizes to be selected and can cope with the deterioration of the float over time, but also, through the idea of ​​creating three parts—a large wing, a large float body, and a weighted foot—inspired by the attachment of a weight, and the concept of making these parts interchangeable, it can cope with various changes in the conditions of basket fishing, and can even be applied to long-distance casting fishing methods other than long-distance basket fishing. [Effects of the Invention]

[0031] The float for long-distance cage fishing of this invention is of medium length, making it easier to cast than longer floats. Furthermore, three fluid dynamics techniques are employed to minimize the deceleration of the maximum speed achieved during casting, thereby increasing the casting distance of the cage rig as well. As a result, regardless of the depth of the fishing spot, by landing the float near the landing point of the cage rig, the cage rig can sink at the point where the float landed, allowing the cage rig to be cast to a distant point. These effects mean that even if the weight of the weight on the cage rig is reduced to compensate for the weight attached to the float, the overall casting distance of the rig, including the float, can be increased compared to conventional methods.

[0032] After hitting the water, the large, teardrop-shaped float's distinctive feature allows it to rise significantly above the water's surface, enhancing static visibility with minimal impact from differences in basket size. Furthermore, by utilizing the restoring force between the submerged center of gravity and the buoyancy center above it when the float is tipped over by waves or crosswinds, it induces an uprighting motion, adding dynamic visibility.

[0033] In short, the float of this invention can synergistically enhance visibility in both static and dynamic ways. Furthermore, the float's upward movement has an attractive effect on fish, and the large float body and teardrop shape generate significant buoyancy, which also improves the hook-up rate of fish.

[0034] In other words, the teardrop-shaped float has three effects: long-distance casting effect, surface buoyancy effect, and righting motion effect. Of these effects, the surface buoyancy effect and righting motion effect are achieved through a synergistic effect of static and dynamic visibility, as well as an attractive effect on fish. In addition, the features of the teardrop shape include not only improving the hook-up rate of fish by making the float larger, but also making it easier to cast by keeping the float length to a medium length, and allowing the use of a wide range of cage rig sizes. From the above, it can be seen that the form of the teardrop-shaped float brings many excellent functions and features to the long-distance cage fishing float of the present invention.

[0035] Furthermore, in the embodiment of claim 2, since the weight, foot, and / or large wing are interchangeable, it becomes unnecessary to prepare each of the various colors and sizes of floats that have been used in conventional long-distance cage fishing. In addition, it becomes possible to replace the wing with a luminous float for fishing that spans the gaps where fish activity is highest, or for night fishing.

[0036] The embodiment of claim 3 claims an embodiment in which the application is not limited to long-distance casting fishing. That is, by replacing the weight with a larger weight, self-supporting flight and buoyancy are made possible, thereby enabling application to various fishing methods, especially long-distance casting fishing methods.

[0037] The float for long-distance cage fishing of the present invention is not only a cost-effective tool for anglers, but also contributes to reducing the waste of fossil resources caused by the mass production and consumption of floats, and to reducing marine plastic waste caused by loss, misplacement, and discarding by anglers. In other words, the embodiments of claims 2 and 3 are extremely rational from both an economic standpoint for anglers and a resource and environmental conservation standpoint.

[0038] The features of the medium-length float of the present invention for long-distance cage fishing can be summarized as follows: casting performance, flight performance, wide buoyancy performance, visibility performance, fish-attracting performance, fish-hooking performance, portability, versatility, and environmental performance. In addition, the selectability of combining the components of the float of the present invention (weighted foot, large floating body, and large wing) according to the application should lead to the discovery of possibilities for various fishing methods, not just long-distance cage fishing. Furthermore, for example, in calm conditions, the float of the present invention extends far above the water surface, making it possible to some extent to identify the fish species by observing the movement of the float.

[0039] Based on the above, the float for long-distance cage fishing of the present invention is characterized by having various functions and unique features, as it incorporates ingenuity to efficiently achieve multiple objectives and a structure to realize them. [Brief explanation of the drawing]

[Figure 29] This figure shows a typical long-distance casting cage as a reference example of the shape of the float used in the present invention. [Modes for carrying out the invention]

[0041] First, we will consider the best mode for carrying out the present invention. <Considerations on medium-length floats>

[0042] Generally, floats 1' used for long-distance cage fishing are often short (Figure 23b). In addition, there are also thicker ones, such as cylindrical ones. While these floats 1' are suitable for casting, as mentioned above, they have problems with flight distance and visibility (Figures 16b-c, 17b-c, 19-20, 21b-c, 24b, 27b). On the other hand, a long float of about 60 cm (1″) offers high visibility but is difficult to cast (Figures 14b, 24c, and 27c). In contrast, the float 1 for long-distance cage fishing of the present invention is characterized by its medium length of about 33 cm to 40 cm. Medium-length floats 1 are also more difficult to cast than short floats 1′ (Figure 13). One possible solution to this problem is to devise a casting method. With the casting method shown in Figure 15, casting becomes possible regardless of the length of the float.

[0043] In a gravity-free state at normal temperature and pressure, liquids such as water tend to maintain a spherical shape due to their surface tension. This is because a sphere has the smallest surface area for the same volume, and the surface tension attempts to minimize the surface area. When free fall occurs from this state, the spherical liquid deforms due to the balance of mass, air resistance, and surface tension, and the sphere becomes a droplet shape. As the falling speed increases with free fall, the air resistance increases, and the upper end of the droplet elongates into a slender shape. Thus, it can be said that the shape of the liquid during free fall is the most suitable for flight. Considering the floating body shape of the float from a hydrodynamic perspective in this way, it can be seen that the droplet shape is optimal for the floating body of the float. Incidentally, the volume (V D ) of the droplet can be considered on the premise that the original spherical shape is stretched only in one direction by the action of gravity. The volume of a sphere can be obtained from 4÷3×(radius) 3 ×pi (π). That is, V D can be derived in an approximate form from the formula for calculating the volume of this sphere. V D is easier to understand if we consider that the volume of the sphere remains unchanged, the radius is stretched only in one direction, and the remaining cross-section becomes smaller. That is, two of the three radii are taken as the cross-section of the droplet-shaped floating body, i.e., r 2 , and the remaining one is taken as half of the length L of the droplet-shaped floating body, i.e., 1 / 2·L. Based on this, approximately the following formula (1) is given based on the calculation formula for the volume of the sphere. Here, let pi π, the radius r of the droplet, and the length L of the droplet be used. The volume V of the droplet D ≈1 / 2·L×4 / 3·πr 2 (1) =2 / 3·πr 2 L According to this calculation formula, if the length direction L of the droplet-shaped floating body is doubled from the original sphere, it becomes 2×1 / 2·L, while the value of r 2 related to the cross-section becomes 0.5. Furthermore, if L is tripled, the value of r 2 becomes 0.333…. Therefore, considering the premise that the volume is constant, the validity of the calculation formula (1) should be confirmed. When this calculation formula (1) is applied to the teardrop-shaped floating body of the present invention, the radius r related to the cross-section corresponds to the maximum width of the floating body, and the length L corresponds to the length of the floating body.

[0044] On the other hand, the floating body of a float must also function as a buoyancy source. Therefore, the density (mass per unit volume) of the floating body must be kept as low as possible to increase the buoyancy of the float. To lower the density of the floating body, a teardrop shape can be formed using a light material such as foam. Examples of foam materials include expanded polyethylene (PE), expanded polystyrene (EPS), extruded expanded polystyrene (XPS), expanded polypropylene (EPP), polyurethane (PU), and ethylene vinyl acetate (EVA). When using these foam materials, it is necessary not only to make them resistant to cracking and tearing and to maintain their shape, but also to minimize the air resistance the float experiences during flight. To achieve this, it is important to make the surface of these foam materials as smooth as possible and to make the airflow over the surface of the floating body laminar, thereby reducing air resistance.

[0045] Therefore, let's consider the representative form of the teardrop-shaped, or nearly teardrop-shaped, large float for long-distance cage fishing of the present invention, as shown in Figure 1. Hereafter, shapes that are nearly teardrop-shaped will also be treated as teardrop-shaped. For example, let's consider its use with a No. 12 cage rig (assuming a load of 75g on the water surface). A large teardrop-shaped float made of foam material with a maximum radius of 2cm and a length of 20cm (density 0.03g / cm³) 3 If manufactured using the method described in equation (1), its volume is 167.5 cm³. 3 It will be to that extent. Now, let's consider the buoyancy of this floating body. The buoyancy (F) can be calculated using the following equation (2). Buoyancy force F=(ρ f ―ρ s )Vg (2)

[0046] However, the density of seawater ρ f = 1.025 g / cm³ 3 (Salinity 3.5%, 20℃), density of floating body ρ s = 0.03 g / cm³ 3 The volume of the large floating body V = 167.5 cm³ 3, gravitational acceleration G=9.8 m / s 2 Therefore, the buoyancy F of the large floating object is approximately 1.63329 N [kg·m / s²] 2 ] and dividing this value by the acceleration due to gravity g gives the load required to sink this floating object. That is, The weight required to sink a large floating object = Buoyancy of the large floating object (F) / Gravitational acceleration (G) ≈1.63329 / 9.8 ≈ 0.16666 [kg] This shows that the large float alone can exert a load of approximately 167g on the sea surface. Considering the size of the weight, this is equivalent to approximately 44.5 units, since each unit weighs 3.75g. Furthermore, as can be seen from this calculation method, when using the float of the present invention for sea fishing, the volume of the float and the load that can be exerted on it are almost equivalent, if the units are ignored.

[0047] Next, we will consider the air resistance acting on a large floating object. Air resistance is the resistance that an object experiences when moving through the air, caused by friction and pressure with the air, and it changes with speed. This air resistance is the drag force (F D It can be expressed as follows by equation (3), where the density of air ρ = 1.225 [kg / m³]. 3 ], velocity of the object V [m / s], drag coefficient C D Projected area (cross-sectional area of ​​large floating object) A [m²] 2 ] Drag F D = 1 / 2·ρV 2 C D A (3)

[0048] This represents the drag force (F) of air resistance. D The drag coefficient (C) is what affects ). DIt is determined by the shape of the object, the smoothness of the surface (laminar flow or turbulent flow), and the Reynolds number (Re). Incidentally, the smaller the drag coefficient, the less affected the object is by air resistance. To obtain the drag force, it is first necessary to determine the Reynolds number (Re). The action governed by whether it is laminar flow or turbulent flow is different. When a smooth surface and a stable flow are obtained, laminar flow occurs at a low Reynolds number, where the viscous force is dominant. On the other hand, when the surface is rough and disordered vortices or unstable flows occur, turbulent flow occurs at a high Reynolds number, where the inertial force is dominant. Regarding the Reynolds number of the floating body shape related to the present invention, we will consider it on the premise that laminar flow with a smooth surface and a stable flow is generated.

[0049] Among floating bodies, the shape estimated to have the smallest drag coefficient is the teardrop shape, and its length / diameter (L / D) is 4 - 5. In the case of the floating body shown in Fig. 1, the length is 20 cm and the diameter is 4 cm, so L / D = 5, which can be said to be within the range of the optimal form as a floating body. If this floating body flies while the floating body surface is smooth and laminar flow occurs, the drag coefficient (C D ) is estimated to be extremely small, about 0.05. From these results, with a projected area A ≒ 0.00126 m 2 , and assuming the speed V = 20 m / s (72 km / h) when the float flies due to the acceleration during throwing, the drag force (F D ) can be estimated to be about 15 mN.

[0050] Subsequently, consider the typical form of Fig. 5 of the float for long - distance cage fishing of the present invention. This time, assume the use of an 18 - gauge cage rigging (assuming a load of 100 g on the water surface). If a large teardrop - shaped floating body is made of foam with a maximum radius of 2.25 cm and a length of 20 cm, its volume will be about 211.9 cm 3 from Equation (2). Here, the buoyancy (F) of this large floating body is about 2.07 N from Equation (3), and the load required to sink this large floating body is about 211 g. Therefore, it can be seen that a load of this size can be applied on the sea surface. In terms of the size of the sinker, this corresponds to about 56.2 sizes.

[0051] Next, consider the air resistance acting on this large floating body. In the case of this floating body, L / D = 4.44. If the surface of this floating body is as smooth as that of the floating body in the representative example of FIG. 1, the drag coefficient (C D ) is estimated to be about the same 0.05. From these results, the projected area A≒ 0.00159 m 2 , and assuming the flight speed of the float is V = 20 m / s, the drag force (F D ) can be estimated to be about 19.5 mN (about 26% increase: compared to the representative example of FIG. 1). Therefore, in the typical form of FIG. 5, the influence of the increase in the cross-sectional area (projected area) due to the larger diameter is greater than the effect of reducing the L / D ratio, and it was found that the reduction of the drag force (F D ) indicating air resistance cannot be expected. However, since the assumed flight speed of the floating body was high, for example, if it is suppressed to about 15 m / s (54 km / h), there is a possibility of reducing the influence of the drag force.

[0052] Let's also consider the typical form of FIG. 6 of the float for long-distance cage fishing of the present invention. Similar to the representative example of FIG. 5, the use of a No. 18 cage rigging is assumed. If a droplet-shaped large floating body is made of a foam material with a maximum radius of 2 cm and a length of 25 cm, its volume will be about 209.3 cm 3 from Equation (1). Here, the buoyancy (F) of this large floating body is about 2.04 N from Equation (2), and the load required to sink this large floating body is about 208 g. Therefore, it can be seen that a load of this magnitude can be applied above the sea surface. Considering the size of the sinker, this corresponds to about 55.5 sizes. From the above, if the float of the form of FIG. 6 is actually manufactured, the length of the large floating body is preferably 24 - 26 cm.

[0053] Next, consider the air resistance acting on the large floating body. In the case of this floating body, L / D = 6.25, which is slightly outside the optimal range where the drag coefficient can be kept small. However, if the surface of this floating body is as smooth as that of the floating body in the representative example of FIG. 1, the drag coefficient (C D ) is estimated to be about the same 0.05. From these results, the projected area A≒ 0.00126 m2 If the flight speed of the float is V = 20 m / s, then the drag force (F D The force can be estimated to be approximately 15.4 mN (equivalent to the representative example in Figure 1). Therefore, in the representative form of Figure 6, by returning the diameter to the original 2 cm and extending the length to 25 cm, it is possible to effectively reduce the effect of air resistance rather than the effect of the increase in the L / D ratio when the travel speed is high. In the first place, considering that it is not easy to fill a No. 20 cage with chum bait and make the flight speed of the entire cage rig reach V = 20 m / s, the advantage of reducing the size of the cage rig to around No. 15 to 18 with the float 1 of the present invention is significant.

[0054] For reference, the drag coefficient (C) of the floating body portion of the typical float shown in Figure 6 is the same length (25 cm) and maximum radius (2 cm). D Comparing the estimated values, the teardrop shape is approximately 0.05 as mentioned above, while the spindle shape with a bulge in the front third is 0.07, the spindle shape with a bulge in the center is 0.09, the cylinder with hemispheres at both ends is 0.42, and the cylinder with a hemisphere at only one end is 0.90. From the above, comparing only the flight performance of the floating bodies, we can see that teardrop shape > spindle shape (bulge in the front 1 / 3) > spindle shape (bulge in the center) > cylinder with hemispheres at both ends > cylinder with a hemisphere at only one end (rear end cross section), indicating that the closer the shape is to a teardrop shape, the easier it is to reduce drag. On the other hand, when the rear end is a sphere or cross section, turbulence is more likely to occur, increasing drag and making it unsuitable for long-distance throwing. <Considerations on the optimal float configuration for flight>

[0055] A floating structure alone cannot ensure flight stability. Therefore, we will consider the best form for implementing the float for long-distance casting cage fishing according to the present invention.

[0056] The distinctive features of the float of this invention, besides the large float being teardrop-shaped, include the adoption of a weight and large wings, which have not been considered in conventional cage fishing. There is a reason why weights have not been attached to floats for long-distance cage fishing until now. This is because, in cage fishing, since the cage needs to be heavy enough for long-distance casting, and then filled with chum bait before being cast, the rest of the rig needs to be kept light.

[0057] However, on the other hand, there are some anglers who can cast a basket rig of about size 12 over 100 meters. Incidentally, the reason why a size 20 basket rig can be cast so far is simply because they are relying on their arm strength and utilizing the recoil force of the rod. Moreover, under the conditions under which a size 20 basket rig can be cast so far, there was a problem in that the float, which has a large buoyancy, exerts a strong braking force on the flight of the basket rig due to air resistance.

[0058] In fact, even with a cage rig weighing around size 12, it is physically possible to cast it more than 100 meters. However, there are conditions for this, which depend on the rod and reel, the shape of the cage rig, the line size, etc. But in relation to the present invention, the float should not hinder the flight of the lightweight cage rig, which has low inertia in the air, as much as possible.

[0059] In light of the above issues, we will now specifically consider the necessary configuration for the flight of the float for long-distance cage fishing according to the present invention. To solve the above-mentioned problems, the float should be designed to maintain high flight performance after the acceleration is maximized when the cage rig is cast. To do this, first, it is necessary to fix a weight in the direction of travel while the float is in flight to obtain a stable inertial force due to the forward center of gravity. However, it is difficult for an object to continue flying stably in the air if it is only heavy at the front during flight. Therefore, in order to minimize the deceleration of the maximum speed, a tail fin, like that of an airplane, is necessary to stabilize the attitude, especially the function of both a vertical and horizontal stabilizer.

[0060] Here, we will consider the ideal and synergistically effective structure for large biplane wings and weights, including their shape, size, material, and mounting position.

[0061] First, regarding the large wings, it is necessary to consider their visibility on the water surface, which will be discussed later. Larger wings are also important for improving the flight performance of the float when thrown. Here, we have adopted a large wing shape, size, material, and number that is considered optimal based on experience: a total length of 10 cm, a maximum width of 5 cm in the upper half, tapering towards the lower end, a thickness of 0.4 mm, made of polycarbonate, and consisting of three wings (fixed radially at 120° equal intervals). However, the shape of the float of this invention is not particularly limited.

[0062] However, a 0.4mm thick polycarbonate sheet has a flexing effect and is highly effective in suppressing turbulence in large wings. For reference, if the thickness is reduced to 0.3mm, the aircraft often flies with a buzzing sound. Also, when there are four wings, the center of gravity during flight is slightly further back, so to prevent this, the wing size needs to be smaller than in the case of three wings. As a result, the role of the tail fin in this invention, namely the roles of the vertical and horizontal stabilizers, is also reduced.

[0063] Furthermore, regarding the wing's mounting position, if durability is required for practical purposes, the lower edge of the wing, approximately 0.5 cm, should be embedded and fixed to the upper part of the float (Figures 1 and 8). However, in this case, the airflow may be slightly disturbed near the wing root. As a result, the drag in the direction of the float's movement will increase slightly. Therefore, to minimize drag when flight distance is desired, it is best to position the large wing 4 about 0.5 cm to 1 cm away from the float 2 (Figures 5 to 7). However, if the distance from the float is 2 cm or more, turbulence is more likely to occur, which can easily hinder the flight of the cage-rigged float.

[0064] For weight 5, the upright motion on the water surface must also be considered. Furthermore, the density of the material affects the size of weight 5. Generally, lead (11.3 g / cm³) is a commonly used material for weights. 3 ) and brass (approximately 8.5 g / cm²) 3 ), stainless steel (approximately 7.8 g / cm³) 3 ), tungsten (19.3 g / cm³) 3Examples include lead weights (equivalent to gold). Unless otherwise specified, this discussion will focus on the most common type, lead weights.

[0065] When using the weight 5 in the float 1 of the present invention, it is necessary to consider the air resistance acting on the weight itself, the total weight of the float as a whole, the position of the center of gravity, and the overall flight performance of the float 1.

[0066] In the float 1 shown as a representative example in Figure 1, a weight 5 is fixed to the bottom of the float body 2. For example, in the case of a handmade float (Figure 8), the float body 2 often breaks due to the impact it receives when it hits the water. Therefore, as a measure to prevent damage to the float body 2, a weight 5 is sometimes fixed to the bottom of the float body 2. Suitable shapes for the weight 5 in this case include through-hole weights for worm sinkers (shaped like half a spindle), conical sinkers, or spindle-shaped teardrop or round sinkers cut in half.

[0067] However, for mass production, it is ideal to fix the weight 5 to the legs 6, as this lowers the center of gravity (forward center of gravity during flight) for stable flight posture and reduces drag caused by the weight 5 itself (Figures 2b-e). When the weight 5 is fixed to the legs 6 in this way, the tip of the legs 6 and the weight 5 become the leading part during flight, so a rounded shape that minimizes air resistance is preferable. Considering practicality, the shape of the weight 5 should be one that is easily available (rod weight, teardrop weight, or eggplant weight). Among these, the shape that reduces drag the most is when using an eggplant weight that is close to a teardrop shape (Figures 2d-e). Also, when the weight 5 is made between the bottom of the float and the legs, the material can be either a cylindrical lead weight with a through-hole passed through the shaft 3, or it can be integrated with the legs 3(5) using stainless steel or brass (Figure 2b).

[0068] Furthermore, considering practicality, economy, and environmental considerations, it is preferable to have a configuration in which the leg 6, including the weight 5, can be replaced, as illustrated in Figure 3, or a configuration in which the leg 6, including the weight 5, the large wing 4, and the float 2 can be replaced, as illustrated in Figure 4. In this case, the large wing 4 can be made to have a color and luminous wings, the float 2 can have a color and size, and the weight 5 can have a shape and size that can be changed. Such a configuration can be adapted to various situations in long-distance cage fishing. As for the weight of the weight 5, assuming that the weight of the float excluding the weight 5 is about 12g to 15g, depending on the float volume, stability during flight, and gliding performance, a weight of about 1.5 to 3.5 (5g to 13g) is suitable for the configurations in Figures 1 to 4, and a weight of about 2 to 4 (7g to 15g) is suitable for the configurations in Figures 5 to 6.

[0069] In the form of the float 1 shown in Figures 1 to 6 of the present invention, even though it cannot fly independently, it can fly simultaneously with the basket rig 14 at the maximum speed reached by throwing, with as little braking as possible. This is because, separate from the float stopper string portion 13, frictional resistance is generated in the part where the main line 10 is caught on the foot 6 and bends slightly, creating a traction that causes the float 1 to fly together with the basket rig 14. This force that pulls the float 1 then triggers a slight pull on the basket rig 14 in the air.

[0070] The float 1 of the present invention is characterized by having a large wing, a large teardrop-shaped float, and a weight, and this characteristic is generated by a small towing force from the cage mechanism. In other words, this towing force is the trigger for synergistic enhancement of many flight performance aspects, such as the straight-line stability and horizontal attitude ensured by the weight and large tail wing, the range stability provided by the teardrop-shaped float, and the gliding effect of the horizontal tail wing that captures the airflow. These mechanisms will be explained in detail in the discussion in Example 6 described later.

[0071] From the above, it should be noted that in the configurations shown in Figures 1 to 6, there is no need to use heavy baskets for long-distance basket fishing except in strong winds or when targeting deep shelves. That being said, the float of the present invention can adequately handle buoyancy even with heavy baskets of size 20 or larger. Thus, one of the features of the float for long-distance basket fishing of the present invention is that, even when using a smaller size basket, both the basket rig 14 and the float 1 can be cast further, compared to when using the conventional float 1'.

[0072] Furthermore, the float 1 of the present invention can be modified from the form shown in Figure 6 to the form shown in Figure 7. In the form shown in Figure 7, by replacing the weight 5 with one of approximately 10 to 30 (35g to 115g) weights, it can be given self-supporting flight, buoyancy, and the ability to right itself. This form of float 1 can be applied to light cage fishing with a cage weight of 10 or less, as well as to long-distance casting fishing methods other than cage fishing. In addition, in the form shown in Figure 7, weights 5 of various sizes, shapes, and materials can be replaced, and it has a wide range of buoyancy and weight, so it can be applied to a variety of long-distance casting fishing methods other than cage fishing.

[0073] The embodiments of the float 1 of the present invention shown in Figures 1 to 7 above are not limited in any way unless otherwise specified. Therefore, although the embodiments illustrated in Figures 1 to 7 have preferred conditions, these conditions are not limited unless otherwise specified.

[0074] In particular, while a suitable size is indicated for the large wing 4, a variety of combinations are conceivable regarding material, color, presence or absence of luminescence (fluorescent, phosphorescent, light), and whether or not it is replaceable. Similarly, for the weight 5, although there is a suitable condition of fixing it in the direction of flight, a variety of combinations are conceivable regarding material, shape, specific fixing position, and whether or not it is replaceable, just like with the large wing. A variety of combinations are also conceivable regarding the material, size, shape (teardrop shape and near-teardrop shape), color, presence or absence of luminescence (fluorescent, phosphorescent), and whether or not it is replaceable for the float 2. Likewise, for the leg 6, although there is a suitable condition for the length from the bottom of the float 2, a variety of combinations are conceivable regarding material, shape, weight fixing method, and whether or not it is replaceable.

[0075] Incidentally, the length of the leg 6 from the bottom of the float 2, along with the position of the weight 5, is an important factor for flight performance and the righting motion described later. In the float 1 of the present invention, the length from the bottom of the float 2 to the leg 6 is approximately 10% to 15% of the total length of the float 1 (total length 33 cm to 40 cm), preferably 3 cm to 6 cm. However, if the purpose is to attract fish and long-distance casting performance is not a concern, the leg 6 from the bottom of the float 2 may be extended to 10 cm or more, as shown in the configuration of Figure 26b. <Considerations on the optimal float shape for visibility>

[0076] Despite being a medium-length float (total length 33cm to 40cm), the float 1 of this invention incorporates numerous features that enable long-distance casting of the cage rig 14. Therefore, even when actually casting long distances, the float 1 must be visible from afar. In order to improve visibility, the float 1 of this invention incorporates many improvements from previous long-distance cage fishing floats 1' and 1''.

[0077] As shown in the example of the extra-large wings (length 11 cm, maximum width 6.5 cm) previously manufactured in Figures 28d-g, wing size is important for improving visibility. In the float 1 of the present invention, the large wings (length 10 cm, maximum width 5 cm) 4 play an important role not only in stable flight using the weight 5, but also in improving visibility. In particular, improving visibility with wings 4 is one of the important means for the float 1 of the present invention, which enables long-distance casting of the cage rig 14.

[0078] Regarding the number of large wings 4, if four wings are used, their size must be reduced to improve flight stability, which reduces visibility. Also, on the water surface, the rotation of the float 1 periodically changes the area of ​​the wings visible from the side, further reducing visibility. Therefore, it is preferable to have three large wings 4 arranged at equal intervals of 120°, as shown in the configuration of Figure 1.

[0079] Furthermore, to improve the overall visibility of the float 1, it is desirable to have as much of the float surface S as possible. However, in the long 1″ form shown in Figure 23c, which was made in the past, not only was it difficult to cast long distances (Figure 14b), but in terms of visibility, the advantage of being long was not fully utilized because the floating portion was small despite its length (Figure 24c).

[0080] On the other hand, the medium-length float 1 of the present invention condenses the shortcomings of such long floats 1''. Specifically, the large teardrop-shaped float 2 provides stable and large buoyancy, and because the area near the widest point of the bottom of the float (the bulging part) is at the water surface, the floating portion is larger, improving the static visibility of the float 2 as well. Not only that, but by positioning the center of buoyancy of the float as close as possible to the water surface relative to the center of gravity which is deeper than the float 1, an upward movement is induced, further improving dynamic visibility. In addition, as shown in Figure 25, this upward movement also synergistically provides an attractive effect to fish, which is another feature of the float 1 of the present invention.

[0081] One way to further improve visibility is to cleverly utilize the properties of light. For example, even if an object has a complex shape when it is close up, as it moves away and eventually becomes invisible, it will only appear as a single point. In such cases, if the float 1 has a two-tone color scheme that includes an expanding color, or if multiple colors are combined in the color scheme, interference between the colors occurs, often reducing visibility.

[0082] However, there are exceptions. For example, if wing 4 is black and float 2 is fluorescent yellow, when the fluorescent part is illuminated by sunlight, it can appear as bright as if a high-intensity light were on, even in daylight. This is because the simple color scheme has high contrast, and the black color of wing 4 on top absorbs reflected light from the surroundings, making the distant fluorescent yellow light stand out.

[0083] With this exception, in order to make the float 1 of the present invention visible from a distance, the floating body 2 and the large wing 4 should be color-coordinated. For example, if they are all black, they will be easily visible in backlit or cloudy conditions, or if they are all yellow or orange fluorescent colors, they will be easily visible when the sea surface is azure as they are complementary colors. As a result, even if the rig is carried away by the current after being cast far away and eventually converges to a single point, visibility will be maintained until the very end.

[0084] Another possible way to improve the visibility of the medium-length float 1 of the present invention is to leave a gap of 5 cm or more between the float body 2 and the wing 4. However, as mentioned above, this would result in a longer float and could easily lead to turbulence and reduced flight stability, making it not a suitable configuration.

[0085] Considering the various favorable conditions described above, let's consider the relationship between the center of buoyancy and the center of gravity necessary for the righting motion of the float 1 of the present invention. First, the center of gravity of the entire cage rig, including the float 1, is deeper than the float 1 as a whole. Next, let's consider the center of buoyancy. The center of buoyancy is the center of buoyancy and corresponds to the position of half the volume of liquid displaced by the object. The distance from the water surface to the deepest point when an object is floating on water is called the draft. In the case of the float 1 of the present invention, the position of the center of buoyancy is concentrated near the maximum radius located at the bottom of the teardrop-shaped float 2 with respect to the depth to which the float 1 sinks due to the weight of the float 1 and the load of the cage rig 14 acting on the water surface (distance from the water surface to the lower end of the float foot 6), i.e., the draft depth. Therefore, even if the size of the weight of the long-casting cage 15 changes somewhat, it can be seen that in the case of the float 1 of the present invention, the center of buoyancy remains in a position very close to the water surface. To summarize the above, in the case of the float 1 of the present invention, the following can be seen. However, the same applies to floats 1' and 1'' for points 1 and 2. 1. The center of gravity of the entire cage rig is deeper than the center of gravity of the entire float. 2. The center of buoyancy is located above the center of gravity. 3. Furthermore, its center of buoyancy is concentrated at a position extremely close to the water surface. The main reason why the float 1 of the present invention is likely to undergo a rising motion is item 3. In addition, it can also be mentioned that the surface area floating on the water surface is large. Based on the embodiments, it will be clarified that the float 1 of the present invention is likely to undergo a rising motion.

[0086] As a representative example among FIGS. 1 to 4, one form (a form similar to FIG. 2d) is exemplified. The float 1 has a total length of 33 cm, large wings 4 (three-wing polycarbonate wings, length 10 cm, maximum width 5 cm, thickness 0.4 mm, embedded and fixed in the floating body 2 by about 0.5 cm and arranged at equal intervals of 120°), a droplet-shaped floating body 2 (length 20 cm, volume 168 cm 3 approx., density 0.03 g / cm 3 ), a shaft 3 (made of lightweight, high-strength, and high-elasticity carbon with a diameter of 1.8 mm, fixing the wings, floating body, and weight), and as the weight 5, an eggplant-shaped lead weight No. 3 (about 10.5 g) is fixed to the leg 6 extending 4.5 cm from the bottom of the floating body 2. The total weight of the float 1 is about 22 to 25 g, and the use of a No. 12 cage device 14 (the load on the water surface after releasing Komase bait, etc. is 75 g, equivalent to a No. 20 weight) is assumed. As an approximate position from the leg 6 of the float 1, since the water surface position is about 8 cm, the center of buoyancy is about 3 cm from the water surface position. This assumption is close to the states of FIGS. 9e and 10 and should contribute to the rising stability and restoring force on the water surface.

[0087] Subsequently, as a representative example of FIG. 6, one form (a form similar to FIG. 6c) is exemplified. The form of the float 1 different from the representative example among FIGS. 1 to 4 has a total length of 40 cm, a droplet-shaped floating body 2 (length 25 cm, volume 210 cm 3 approx.), as the weight 5, an eggplant-shaped lead weight No. 3.5 (about 13.5 g), the total weight of the float 1 is about 26 to 29 g, and the use of an No. 18 cage device (the load on the water surface after releasing Komase bait, etc. is 100 g, equivalent to a No. 27 weight) is assumed. As an approximate position from the leg 6 of the float 1, since the water surface position is about 10 cm, the center of buoyancy is about 4 cm from the water surface position. This assumption should also contribute to the rising stability and restoring force on the water surface.

[0088] Furthermore, in order to fully realize the intended performance of the float 1 for long-distance cage fishing of the present invention, it is necessary to take advantage of the feature that allows the float to be lighter than the specified cage rig 14 size. Therefore, even when using a float 1 with the same total length of 40 cm and a cage rig 14 of size 12 (a load of 75 g on the water surface after the release of chum bait, equivalent to a size 20 sinker), the approximate position from the foot 6 of the float 1 to the water surface is around 8 cm, so the center of buoyancy is around 3 cm from the water surface. Even with this assumption, it should be possible to contribute to the stability and restorative force when the float is righted on the water surface. If, however, only the fish-attracting effect through the righting motion is desired, ignoring the flight performance, the length from the bottom of the float 2 to the foot 6 can be extended as shown in Figure 26b (Figure 27a).

[0089] In summary, we examined the conditions necessary for the float 1 to right itself when the load of the cage rig 14 used in actual operation is applied to the float 1, for configurations similar to those in Figures 2d and 6c. As a result, we found that even when the load of the cage rig 14 is changed within the normal operating range, the float 1 can right itself without significant changes in the position of the water surface or the center of buoyancy. This is because, although the distance from the foot 6 to the bulging part of the teardrop-shaped float 2 is slightly different, the material and diameter of the float 2 used in these two configurations of float 1 are the same.

[0090] As these results show, due to its unique shape, the float 1 of the present invention can flexibly accommodate a variety of sizes of cage rigs 14, from flight performance to uprighting motion accompanied by buoyancy. Furthermore, by utilizing its individual functions, such as the effect of dynamic visibility associated with the uprighting motion (Figures 26-27a), the effect of attracting fish (Figure 25), and the effect of improving hook-ups due to its large buoyancy, it also holds diverse possibilities for other long-distance casting fishing methods. The present invention will be described below with reference to examples, but the present invention is not limited in any way to these examples. [Examples]

[0091] Figure 1 is a representative diagram illustrating one embodiment of the float 1 for long-distance cage fishing according to the present invention. The floats illustrated in the embodiments of the present invention are mainly of medium length, with a total length of approximately 33cm to 40cm. However, the total length of the float 1 is not particularly limited as long as it is within the scope of the features of the present invention. Therefore, even if the float is short, less than 30cm in length, it is not limited to cage fishing as long as it possesses many of the features of the float 1 of the present invention.

[0092] Figure 1 illustrates a float 1 with a total length of approximately 33 cm to 34 cm, which is the shortest of the floats 1 of the present invention. This float 1 consists of a large wing 4, a large float body 2 with a teardrop shape or a shape close to a teardrop, and parts 2 to 5 that constitute the float 1 of the present invention, including a weight 5 and a foot 6 for passing the fishing line at the bottom (bulging end) of the float body, all fixed to a single shaft 3. The upper figure on the right shows the float 1 as viewed from directly above, and the lower figure shows it as viewed from below. From these figures, it can be seen that the three large wings 4 are arranged at equal intervals of 120°. [Examples]

[0093] Figure 2 shows examples of various forms of the float 1 in Figure 1, illustrating differences in the shape, size, and position of the weight 5. Figure 2a shows a through-type sinker 5 fixed below the float body 2, similar to the float 1 in Figure 1. Figure 2b shows a form in which the weight 5 (3), which also serves as the shaft, is integrated with the foot 6, and also functions as the shaft 3. Figures 2c to 2e illustrate a structure in which the weight 5 is fixed to the foot 6, excelling in long-distance casting performance and righting motion of the cage rig. Figure 2c shows a through-type teardrop-shaped sinker 5, Figure 2d shows an eggplant-shaped sinker 5 with a shaft 3 passing through its interior, and Figure 2e shows an example of Figure 2d with a larger shaft 3. [Examples]

[0094] Figure 3 shows an example of how the weight 5(3), which also serves as the shaft of the float 1 in Figure 2b, and the leg 6 are integrated and made interchangeable. With these configurations, it is possible to adjust the buoyancy and respond to fishing conditions. Figure 3a shows the leg 6 with the weight 5(3) attached to the shaft attached by a screw 7, Figure 3b shows the leg 6 with the weight 5(3) attached to the shaft removed, Figure 3c shows various configurations of the leg 6 with the weight 5, and Figure 3d shows an example of a configuration where the weight 5(3) and the leg 6 are integrated, and the length from the bottom of the float to the leg is greatly extended.

[0095] Figure 26 shows an example of the float 1 in Figure 3a (Figure 26a), and an example of the float 1 in Figure 3a with the weight 5(3) and foot 6 integrated into one unit, as shown in Figure 3d (Figure 26b), when floating on the water surface S. (i) shows the underwater view when the float 1 is floating on the water surface S, (ii) shows the float 1 floating on the water surface after being cast a long distance, i.e., as seen from a distance, and (iii) shows the underwater view when the float 1 is rising up on the water surface S. Compared to the float 1 in Figure 26a, the float 1 in Figure 26b has a longer distance from the bottom of its floating body to its foot, so it can be seen that the up-and-down movement of the cage rig accompanying the rising motion is greater. In other words, it can be seen that the fish-attracting effect is enhanced.

[0096] Figure 27 shows the float 1 from Figure 26b, and the short float 1' and long float 1'' as comparative examples, floating on the water surface S. (i) shows the underwater view when the float is floating on the water surface S, (ii) shows the float floating on the water surface after being cast a long distance, i.e., as seen from a distance, and (iii) shows the underwater view when only float 1 is performing an upright motion on the water surface. Compared with the comparative examples b and c in Figure 27(i),(ii), and(iii), it can be seen that float 1 in Figure 27(i),(ii), and(iii)a effectively generates an up-and-down movement on the cage rig due to the upright motion. In other words, it can be seen that it has a higher fish-attracting effect compared to the comparative examples. [Examples]

[0097] Figure 4 shows an example of the float 1 in Figure 2b, in which not only the leg 6 with the weight 5(3) which also serves as the axis, but also the float body 2 and large wing 4 are interchangeable. With these configurations, not only can the leg 6 with the weight 5 be replaced according to the fishing conditions, but the buoyancy and color of the float body 2, and the color and luminous wing combination of the large wing 4 can be freely selected. Figure 4a shows the float assembled from the leg 6 with the weight 5(3), float body 2, and large wing 4, Figure 4b shows the float with the leg 6 with the weight 5(3) and large wing 4 removed, and Figure 4e shows examples of various configurations of the leg 6 with the weight 5. [Examples]

[0098] Figure 5 shows an example of a configuration in which, in the float 1 of Figure 2b, buoyancy is increased by increasing the maximum radius of the floating body 2, and the long-distance casting performance of the cage rig is further enhanced by fixing the large wing 4 and the floating body 2 at a slight distance from each other. [Examples]

[0099] Figure 6 shows an example of a configuration in which the float 1 of Figure 1 has been modified to increase buoyancy by lengthening the float body 2 in the axial direction, and the large wing 4 and the float body 2 are fixed at a slight distance apart, similar to Figure 5, in an attempt to improve the long-distance casting performance of the cage rig. Figure 6a shows a teardrop-shaped weight 5, Figure 6b shows a leg 6 with a weight 5(3) that also serves as the shaft, Figure 6c shows an eggplant-shaped weight on the weight 5(3) that also serves as the shaft, Figure 6d is a perspective view showing the leg 6 with weight 5(3) integrated with the metal shaft 3, and Figure 6e is a perspective view showing the shaft 3, made of a high-density metal such as brass or stainless steel, also serving as the weight 5.

[0100] Here, we will consider the reasons why the float 1 of the present invention enables the long-distance casting of the cage rig 14 in the embodiments shown in Figures 1 to 6.

[0101] 1. The gravity of the weight 5 becomes the inertial force of the float 1 during flight. This inertial force enhances the straight-line stability provided by the large vertical stabilizer 4, and the forward center of gravity of the weight 5 and the large horizontal stabilizer maintain a horizontal attitude, thereby stabilizing the flight attitude of the float 1.

[0102] 2. The cage rig 14 and float 1 do not fly horizontally during flight. Because the cage rig 14 flies in a parabolic arc, the float 1 connected by the main line 10 flies with the teardrop-shaped bottom of the float body 2 facing the cage rig 14 (Figure 16a). As a result, the main line 10 attached to the float foot 6 is bent by this angle, creating a slight frictional resistance between the float foot 6 and the main line 10. This frictional resistance causes the cage rig 14 to exert a slight pulling force on the float 1. The fact that float 1 flies with the teardrop-shaped bulge at the front of float 2 facing the cage rig 14 means that airflow continuously hits the bulge at the front of float 2. This condition creates a special situation from a fluid dynamics perspective. In other words, the teardrop shape is not only the most effective in reducing drag during flight from a fluid dynamics standpoint, but it is also an excellent shape for generating lift. Lift is a fluid phenomenon that occurs when airflow hits a flying object at an angle of attack. Lift has positive lift (lift force) which points upward and negative lift (down force) which points downward, and when this phenomenon occurs in a single flying object, both types of lift occur at two locations. In the case of a teardrop shape, as a result, a large positive lift acts on the wide, large area of ​​the bottom of the teardrop shape, which is in the direction of flight, and a small negative lift acts on the narrow, small area of ​​the tip at the rear, so float 1 with a teardrop-shaped float 2 gains an upward force. The mechanism will now be explained. In the case of this teardrop-shaped float 2, the angle of the airflow that continuously strikes the bulging portion at the front of the float 2 becomes the angle of attack required to generate lift. An airflow at this angle of attack creates both a high-speed airflow above the object and a low-speed airflow below it. If laminar flow can be maintained in both airflows, the portion of the airflow flowing at high speed above will have lower pressure and a lower air density. On the other hand, the portion of the airflow flowing at low speed below will have higher pressure and a higher air density. As air flows from areas of higher density to areas of lower density, a positive lift force will be somewhat stronger in the bulging portion that occupies a large area at the front of the float. On the other hand, a negative lift force is applied to the rear of the float 2. However, since the rear of the float 2 is the narrow part of the teardrop shape and has a small area, it is less affected by the downward force. In the case of the float 1 of the present invention, since the cage mechanism 14 flies in a parabolic trajectory, this lift force will continue to act from the time of throwing until landing on the water. However, if the positive lift is too strong, it will be impossible to obtain an airflow at the angle of attack. Nevertheless, as explained in section 1, the float 1 of this invention has a strong inertial force that stabilizes the flight attitude, so large disturbances in attitude are unlikely to occur. Therefore, the attitude of the float 1 is quickly returned to the point where the original angle of attack is effective, and it is possible to continue flying while constantly maintaining balance so that the positive lift is just right. Furthermore, although it depends on the shape of the basket, it has been empirically found that making the basket 15 and the float 1 the same radius is important for casting the entire basket rig a long distance, so that the float 1 is effectively pulled in by the downforce generated in the basket 15. From these results, it can be seen that by using a teardrop shape for the float body 2 of the float 1, the drag reduction effect and the positive lift effect are obtained synergistically.

[0103] 3. The cage mechanism 14 in flight exerts a slight pulling force on the float 1, causing the same airflow to hit the large tail fin 4. As a result, the float 1 is able to glide. In this case, the gliding effect is enhanced when there are three large tail fins rather than four, because the two large horizontal tail fins, tilted at -30°, increase the force of the airflow and create a force that pushes the tail fin upwards.

[0104] From the above, it can be seen that the float 1 of the present invention has excellent hydrodynamic features that synergistically exhibit many flight performance characteristics, such as ensuring a horizontal attitude and straight-line stability with the weight 5 and large tail fin 4, cruising stability due to the drag reduction effect and positive lift effect of the teardrop-shaped float 2, and gliding stability with the large horizontal tail fin 4.

[0105] Of the configurations shown in Figures 1 to 6, it was found that the float 1 of the present invention shown in Figure 6c may be the most suitable for flight conditions. One of the reasons for this is that the tip of the float and the large tail fin are separated by only a small distance (approximately 0.5 cm to 1 cm). The best configuration of the present invention is one in which this configuration can be disassembled into a leg 6 in which the large wing 4, the large teardrop float 2, and the weight 5 (3) are integrated, and each component can be freely replaced. [Examples]

[0106] Figure 7 shows an example of a float 1 from Figure 6 with an enlarged leg 6 with a weight 5(3) that can be applied to light cages and other long-distance casting methods. Figure 7a shows a form in which the leg 6 with a large rod-shaped weight 5(3) that also serves as the shaft is integrated with the entire float. Figure 7b shows a form in which the leg 6 with a large rod-shaped weight 5(3) that also serves as the shaft is replaceable. Figure 7c shows the state in which the leg 6 with the weight 5(3) that also serves as the shaft is removed by a screw 7, and Figure 7d shows examples of various forms of the leg 6 with the weight 5. [Examples]

[0107] Figures 8 to 12 provide an overview of the configuration and test results of prototype 1 and prototype 2, which were actually manufactured versions of the float 1 exemplified in Figure 1.

[0108] Figure 8 shows exploded view (a), perspective view (b), front view (c), oblique view (d), and top view (e) of prototype 1 and prototype 2, which were actually manufactured based on the float 1 exemplified in Figure 1. Note that the components, their materials, shapes, and sizes exemplified in exploded view (a) are not particularly limited.

[0109] As shown in the exploded view of Figure 8a, the float 1 of the present invention consists of a large wing 4, a large float 2, two tubes 9 for fixing the upper and lower parts of the float 2 to the shaft 3, a weight 5, and a foot 6, all fixed by the shaft 3. The materials used in the actual prototype will now be described. For the shaft 3, a lightweight, high-strength, and highly elastic 1.8 mmφ carbon solid was used, and the bonding area with other components was increased by sanding. In addition, both sides of the lower end 1 cm were sanded to make them flat. For the large wing 4, a 0.4 mm thick polycarbonate was used, with a total length of 10 cm, a maximum width of 5 cm in the upper half, and a tapered shape towards the lower end. The surface of all cut large wing 4 components was sanded for painting and bonding. The large float 2 is made of foamed polyethylene, with a length of 20 cm and a diameter of 4 cm. After cutting the foam material with a cutter, the surface was ironed using a woodworking lathe, and then the surface was further sanded to make it smooth. Furthermore, three radial cuts of about 0.5 cm were made in the insertion part of the large wing 4. The transparent tube 9 was cut to an inner diameter of 2 mm and a length of 2 cm, and the inner and outer surfaces of the tube were sanded. For the weight 5, a 3 / 16 oz (5.3 g; equivalent to about 1.5 g) lead weight for worm sinkers was used, with the inner wall of the through-hole sanded. For the legs 6, a 1.2 mm diameter piece of hard stainless steel was cut to a length of 3 cm, bent into a U shape, and then sanded.

[0110] Figure 8b shows a perspective view of the components after they have been assembled. Instant adhesive was used to assemble the components. First, three large wings 4 were glued to the shaft 3 so that they were radially spaced at 120° intervals. Then, a tube 9 was inserted into the upper (narrow) side of the large float 2, passed through the shaft 3, and the three large wings 4 were embedded in the notches provided on the upper side of the float 2. The upper part of the large float 2, the large wings 4, the tube 9, and the shaft 3 were then glued together. A tube 9 and a weight 5 were also passed through the lower end of the shaft 3 in that order, so that the head of the tube 9 inserted into the large float 2 fit into the recess of the worm sinker weight 3. The lower part (bottom) of the large float 2, the tube 9, the weight 5, and the shaft 3 were then glued together. Finally, a U-shaped stainless steel material, which will become the leg 6, was glued to the lower end of the shaft 3, aligning it with the two flat surfaces provided at the end of the shaft 3. Furthermore, 0.3mm diameter stainless steel wire was wrapped around and glued in place to form the legs 6. In addition, to withstand violent collisions with the water surface, a weather-resistant elastic adhesive was applied over the adhesive layers on the surfaces of the large wings 4, weight 5, and legs 6 where the super glue was exposed. As a final touch, the large wings 4 and the parts from weight 5 to legs 6 were painted with black water-based acrylic paint.

[0111] The front view in Figure 8c shows the float 1 of prototype 1, which was manufactured using the above process. Figure 8d shows a view of the float 1 of prototype 1 from an oblique angle above, and Figure 8e shows a view from directly above. Figure 8e shows how the large wings 4 are fixed radially at equal intervals of 120°.

[0112] Figure 9 shows the buoyancy test conducted on float 1 of prototype 1 after its manufacture. In this test, weights of 0 (a), 5 (b), 8 (c), 15 (d), 20 (e), 40 (f), 45 (g), and 50 (h) were loaded. The results showed that prototype 1 could be used in a wide range of weights from 8 to 50.

[0113] Figure 10 shows the relationship between the weight load and water surface position S of prototype 1, as determined by the results obtained in Figure 9.

[0114] Figure 11 shows the state of the buoyancy test conducted after manufacturing a prototype 2 in which the float 1 illustrated in Figure 1 was actually manufactured. In this test, weights of No. 5 (a), No. 8 (b), and No. 50 (c) were loaded. As a result, it was shown that the prototype 2 can also be used in a wide range from No. 8 to No. 50, similar to the prototype 1. From the results shown in FIGS. 9 to 11, it can be said that the float of the present invention can cope with a slight decrease in buoyancy due to aging deterioration and a change in the number of the basket with a margin. This can be said to be the result of correctly utilizing the characteristics of the bulging parts at the bottoms of the large float and the droplet-shaped float synergistically.

[0115] Here, let's review the results of the buoyancy tests in Fig. 9 (Prototype 1) and Fig. 11 (Prototype 2).

[0116] Regarding the large float 2, the length is 20 cm and the volume is about 168 cm 3 in calculation, and the weight load should be about 168 g (equivalent to about No. 44.5). However, as shown in Figs. 9 and 11, the buoyancy of the two actually manufactured floats 2 was such that they floated even with a weight load of No. 50 (187.5 g). Therefore, when adding about 18 g of the total weight of the float, the float volume becomes 200 cm 3 or more (about 205 - 210 cm 3 ). This value of the float volume is close to the value (about 210 cm 3 ) of the float length of 25 cm of the droplet body obtained by calculation.

[0117] Therefore, it was found that the bulge on the wing side of the float obtained through prototyping is larger than the ideal droplet shape. That is, it can be said that the float body shape is closer to the droplet shape rather than the droplet shape. Although this bulge slightly affects the long-distance casting of the basket rigging, since it is the floating part, it has little influence on the rising motion and should exert an effect on expanding the buoyancy range and improving the fish-catching hook.

[0118] From the above, it can be considered that in the design for mass production, by making the float body shape closer to the droplet shape, the flying distance of the basket rigging can be further improved. Incidentally, in the two prototype forms shown here, although there are no examples, high flight stability and rising motion have been confirmed in both.

[0119] Figure 12 shows the buoyancy sustainment test conducted immediately after the production of prototype float 1. Tap water (fresh water with a density of 1), which has a density 2.5% lower than seawater, was used in this test. As a result, even after being left for more than 10 hours with a No. 20 weight load, there was no significant difference in the water surface position of float 1. However, in actual cage fishing, float 2 is subjected to continuous strong impacts as it is repeatedly cast about 100m with a cage rig weighing around 100g. While it is difficult to avoid a decrease in buoyancy due to this, float 1 of the present invention has an extremely wide practical buoyancy range, so if not all functions are required, its lifespan is expected to be considerably longer than other floats.

[0120] Figure 13 shows the casting of the medium-length float 1, a representative diagram of the present invention shown in Figure 1. Figure 13a shows the casting of the long-distance casting cage rig 14 shown in Figure 13b. The general long-distance casting cage rig 14 shown in Figure 13b is described in detail in the background art section. As shown in Figure 13a, when casting the medium-length float 1, it is easier to cast than the long-length float 1'' shown in Figure 14b, but not as easy as the short-length float 1′. However, with the casting method shown in Figure 15, the cage rig can be cast regardless of the length of the float by swinging it around in the air without letting it remain still.

[0121] Figures 16 to 21 schematically show the flight performance of the medium-sized float 1 of the present invention, and will be described using the short-sized float 1' as a comparative example. Although the medium-sized float 1 of the present invention is inferior in terms of ease of throwing compared to the short-sized float 1', it can be thrown farther than the setup of the short-sized float 1' by using a weight lighter than the weight of the weight of the basket used for the short-sized float 1' (Figs. 16a to 18a). This figure schematically represents the mechanism. As a concept for using the medium-sized float 1 of the present invention, the portion (about No. 1.5 to No. 3.5) that is lighter than the weight of the weight of the basket used for the short-sized float 1' is moved to the weight 5 of the medium-sized float 1. In other words, the weight distribution of the flying object is dispersed. As a result, the flying distance of the entire setup can be extended without significantly changing the total weight of the basket setup 14 including the medium-sized float 1.

[0122] On the other hand, as described above, when using a general short-sized float 1', when the shelf of the basket setup 14 is deep, the float 1' moves backward due to air resistance during throwing (Figs. 16b to 17b, Fig. 19a). Therefore, the float 1' lands in front of the basket setup 14 (Fig. 19b). When the basket setup 14 sinks, it sinks with the landing point of the float 1' as the fulcrum. As a result, even if the basket setup 14 can be thrown far, the flying distance of the entire setup cannot be increased (Fig. 19c).

[0123] Also, when the shelf of the basket setup 14 is shallow, the float 1' hinders the flight of the basket setup 14 due to air resistance during throwing (Figs. 16c to 17c, Fig. 20a). Therefore, the float 1' lands in front of the basket setup 14 (Fig. 20b). When the basket setup 14 sinks, it sinks with the landing point of the float 1' as the fulcrum. As a result, even if the basket setup can be thrown far, the flying distance of the entire setup cannot be increased (Fig. 20c). Looking at Fig. 21, the difference in the flying distance of the setup between the float 1 of the present invention (Fig. 21a) and the case where the shelf of the basket setup 14 of the general float 1' is deep (Fig. 21b) and shallow (Fig. 21c) is clearly visible.

[0124] Figure 22 shows the float 1 from Figure 1 being cast using a long-distance casting cage rig 14 and floating on the sea surface S. This figure illustrates how the shape of the float 1 of the present invention is characterized by limiting the water ingress of the teardrop-shaped float 2 due to the weight of the long-distance casting cage rig 14 to the bottom of the teardrop.

[0125] Figure 25 shows the float 1 in Figure 22 undergoing an upright motion due to a crosswind W. This figure shows how the form of the float 1 of the present invention exhibits an attractive effect that draws fish in by causing the cage rig 14 to move up and down through the upright motion. <Comparative Example>

[0126] As a comparative example of the medium-length float 1 of the present invention, Figure 28 shows an image of a long float 1" that has actually been manufactured and used for long-distance cage fishing. As shown in Figure 28, the comparative long float 1" has a total length of approximately 50 cm or more, and the shaft occupies most of the length. In many of these forms, the widest part of the float body is positioned on the wing side, similar to commercially available floats, in order to improve static visibility. This ensures that the float remains upright on the water surface, i.e., the water surface is located at the widest part of the float body, thereby maintaining a stable underwater posture (Figures 23c, 24c). Therefore, these forms are not suitable for righting motion, and are contrary to the form that the medium-length float 1 for long-distance cage fishing of the present invention aimed for (Figure 27c). <Reference example>

[0127] Figure 29 shows a commonly used long-casting cage 15 for cage fishing. The long-casting cage 15 consists of an upper cage 16 for holding chum bait and hook bait, and a lower cage 17 to which a weight at the bottom is fixed by an axis 3. A float is built into the inside of the upper cage 16 so that the upper cage 16 floats and opens in the water. Figure 29a shows a cylindrical cage with conical ends, Figure 29b shows a spindle shape, and Figure 29c shows a teardrop shape as examples of long-casting cages. [Industrial applicability]

[0128] The float for long-distance cage fishing of the present invention not only allows for a variety of long-distance cage fishing methods to suit various situations, but can also be used as a self-righting float for long-distance casting by replacing the float's stem with a large weight that matches the size of the cage and float, thus enabling its application to various long-distance fishing methods. For example, examples of long-distance fishing methods include long-distance live bait fishing, long-distance drift fishing, long-distance lure fishing targeting schools of fish, and long-distance sabiki rigs using the righting motion, as well as lure and bow-shaped artificial bait fishing. In particular, this long-distance float can be used in live bait fishing when the fish ladder of large fish is far away.
