DETAILED DESCRIPTION OF THE INVENTION
[0012] A sinker 1 according to an embodiment of the present invention (see FIGS. 2 to 4) is used for fishing and comprises a sinker body 3 and a water-repellent material (water-repellent agent) 5. The sinker body 3 is formed into a predetermined shape from, for example, lead or a lead alloy. The sinker body 3 may also be made of other metal materials such as tungsten or a tungsten alloy, iron (including iron alloys such as steel), bismuth (including bismuth alloys such as lead-free solder), copper alloys such as brass, or a material with a higher specific gravity than seawater (for example, concrete).
[0013] The water-repellent material 5 covers the surface of the sinker body 3 in the form of a film (for example, a thin film) in order to reduce the water resistance (to reduce the water resistance value) when the sinker body 3 (sinker 1) sinks in water. The water-repellent material 5 is coated on the entire surface of the sinker body 3, or on most or half or more of the surface, for example, to cover the surface of the sinker body 3.
[0014] Here, the water repellency of the water repellent material 5 will be explained. Imagine the top surface of a flat object on which the water repellent material 5 is provided. This top surface is assumed to be horizontally extended. When a water droplet is placed on the top surface, the contact angle of the water is 90° or more and less than 180° (preferably 110° or more and less than 180°, and more preferably 140° or more and less than 180°). Note that the larger the value of the contact angle of water, the higher the water repellency. Incidentally, when a water droplet is placed on the surface of hydrophilic glass (flat surface), the contact angle is about 20 to 30°.
[0015] For example, fluororesin or silicone resin is used as the water-repellent material 5. More specifically, super water-repellent clear paint manufactured by Nippon Paint Co., Ltd. is used as the water-repellent material 5.
[0016] The water-repellent material 5 is applied to the weight body 3 by spraying, for example, but the water-repellent material 5 may also be provided on the weight body 3 by plating. Furthermore, the water-repellent material 5 is provided directly on the weight body 3, but the weight body 3 may be subjected to a surface treatment or the like, and the water-repellent material 5 may be provided on the surface that has been subjected to the surface treatment or the like.
[0017] Furthermore, the water-repellent material 5 may be colored so that the color of the weight body 3 and the water-repellent material 5 are different. Also, the weight body 3 may be covered with a film (for example, a thin film of paint) of a different color from that of the weight body 3, and this film may be covered with the water-repellent material 5.
[0018] This makes it possible to easily identify the part of the weight 1 where the water-repellent material 5 is missing, even if the weight 1 is struck or otherwise damaged, and to easily repair the missing part of the water-repellent material 5.
[0019] The sinker body 3 is streamlined. A streamlined shape is a shape that is composed of curves (curved surfaces) that eliminate or minimize the generation of vortices around the sinker 1 when water flows around the sinker 1 (flows along the longitudinal direction of the streamlined sinker 1) as the sinker 1 sinks, thereby reducing the resistance from the flow. For example, as shown in Figures 2 and 3, it is a long, slender shape with rounded ends in the longitudinal direction. It is desirable that the surface of the sinker 1 (sinker body 3) is free of unevenness.
[0020] 2 and 3, a recess 7 is provided on the surface, but it is desirable that this recess 7 be filled with a material such as synthetic resin or metal. Alternatively, it is desirable that the recess 7 not be provided on the weight body 3 itself.
[0021] The weight 1 shown in Figure 2 is formed to be elongated and streamlined, with line eyes 9 protruding from both ends in the longitudinal direction. The weight 1 shown in Figure 3 is also streamlined like the weight 1 shown in Figure 2, with line eyes 9 protruding from both ends in the longitudinal direction. The weight 1 shown in Figure 3 has a slightly larger outer diameter and a slightly shorter length than the weight 1 shown in Figure 2. The weight 1 shown in Figure 4 is spherical, with line eyes 9 protruding from part of the surface of the sphere.
[0022] The sinker 1 is composed of a sinker body 3 formed into a predetermined shape from a metal material, and a film-like water-repellent material 5 covering the surface of the sinker body 3. This allows the surface of the sinker 1 (the surface of the water-repellent material 5) to strongly repel water, reducing water resistance when the sinker 1 moves in water and allowing it to sink quickly in water.
[0023] Further explanation will be given with reference to Figure 1. A conventional sinker 11 not provided with water-repellent material 5 and a sinker 1 according to an embodiment of the present invention are lowered simultaneously into seawater 17 from a boat 13. Note that a device (not shown) is attached to each sinker 1, 11 in the vicinity. Also, as the sinkers 1, 11 sink (fall), there is almost no tension in the fishing line 15, and the sinkers 1, 11 fall freely in the seawater 17 while encountering resistance from the seawater 17.
[0024] When a certain time has passed since the sinkers 1, 11 started to be lowered, the conventional sinker 11 falls slowly and only reaches depth 21 of bycatch fish (for example, blue fish such as mackerel) 19. In contrast, the sinker 1 according to the embodiment of the present invention falls faster than the conventional sinker 11 and therefore reaches depth 25 (deeper than depth 21) of the target fish (for example, deep-sea fish such as alfonsino) 23.
[0025] As a result, when the sinker 1 according to the embodiment of the present invention is used, there is a higher chance of obtaining a higher catch than when the conventional sinker 11 is used. Furthermore, when the conventional sinker 11 is used, the sinker 11 and the tackle sink slowly, so there is a risk that the tackle will be mashed up by bycatch 19 such as mackerel when passing through the upper depth 21. In contrast, when the sinker 1 according to the embodiment of the present invention is used, the sinker 1 and the tackle sink faster, so there is a reduced risk that the tackle will be mashed up by bycatch 19 such as mackerel when passing through the upper depth 21.
[0026] Furthermore, by forming the weight body 3 of the weight 1 from lead, the price of the weight 1 can be made cheaper than when the weight body is made from tungsten, which has a high specific gravity. Furthermore, tungsten often contains small amounts of impurities, making it hard. Lead, on the other hand, is soft, making it easier to mold the weight body 3. By forming the weight body 3 of the weight 1 from iron (including iron alloys such as steel), bismuth (including bismuth alloys such as lead-free solder), or brass, the price of the weight 1 can be made cheaper than when the weight body is made from tungsten. Furthermore, environmental degradation due to lead poisoning can be prevented.
[0027] Furthermore, since the sinker 1 has a streamlined shape, the sinker 1 coated with the water-repellent material 5 also has a streamlined shape. This further reduces the water resistance when the sinker 1 sinks.
[0028] Next, an artificial lure 31 according to an embodiment of the present invention will be described with reference to Fig. 5. The artificial lure 31 shown in Fig. 5 is used for fishing or angling, similar to the sinker 1, and is comprised of an artificial lure body 33 and a water-repellent material 35 similar to the water-repellent material 5 of the sinker 1.
[0029] The lure body 33 is made of synthetic resin and formed into a predetermined shape (for example, a streamlined shape that resembles a small fish). The lure body 33 may be made of wood or bamboo, or may be made of the same metal material as the sinker 1, or may be made of at least two of synthetic resin, wood or bamboo, and metal. The water-repellent material 35 is in the form of a film that covers the surface of the lure body 33, just like the sinker 1.
[0030] The lure body 33 also has a recess 45, but it is desirable to remove the recess 45 as in the case of the sinker 1. The surface of the lure body 33 may be painted to improve the bite of fish. In this case, the water repellent material 35 is provided so as to cover the painted surface.
[0031] The recesses 45 in the lure body 33 may have a shape that imitates scales or the like, different from the shape shown in Fig. 5. It is also desirable that the recesses 45 (including those with shapes different from the shape shown in Fig. 5) are filled (or filled with) a material (for example, synthetic resin) of a color different from the color of the lure body 33. The water-repellent material 35 is provided so as to cover the surface of the lure body 33 in which the recesses 45 are filled.
[0032] In the lure 31, a rear hook 37, a hook eye 39, and a line eye 41 are provided on the lure body 33. A front hook (for example, a fly) 43 is provided on the hook eye 39.
[0033] The lure 31 is composed of an lure body 33 formed in a predetermined shape and a film-like water-repellent material 35 covering the surface of the lure body 33. As a result, just like the sinker 1, the lure 31 faces less water resistance when moving in the water.
[0034] Next, a lure 31 according to another embodiment will be described with reference to Figures 6 and 7. For ease of explanation, the direction perpendicular to the plane of the paper in Figure 6 will be referred to as the horizontal direction of the lure 31, the left-right direction of the plane of the paper in Figure 6 will be referred to as the front-rear direction of the lure 31, and the up-down direction of the plane of the paper in Figure 6 will be referred to as the up-down direction of the lure 31.
[0035] The lure 31 shown in Figure 6 is comprised of a lure body 33 and a water-repellent material 35. The lure body 33 is formed into a predetermined shape from at least one of metal material, synthetic resin, wood, and bamboo.
[0036] The artificial lure 31 is used in fishing and fishing, and as shown in Figures 6 and 7, the artificial lure 31 is provided with a light emitting material 51. Note that the light emitting material 51 may be omitted.
[0037] A recess 53 is provided on the outer surface (surface) of the lure body 33. The lure body 33 and the recess 53 are integrally formed, for example, from a material such as synthetic resin. The recess 53 is recessed from the outer surface of the lure body 33 towards the center of the lure body 33. The luminous material 51 is configured to contain at least one of a phosphorescent material and a fluorescent material (phosphor), and is provided within the recess 53.
[0038] The luminous material 51 is provided to enhance the function (function of attracting fish) of the lure 31. The luminous material 51 is, for example, a mixture of a phosphorescent material or a fluorescent material and a synthetic resin such as urethane resin, and is provided on the lure body 33 by coating.
[0039] The light emitting material 51 is provided in a recess 53 recessed from the outer surface of the lure 31 (lure body 33). As shown in Figure 7(b), the light emitting material 51 is in the form of a film, covering the recess 53 (bottom surface 57 of the recess 53 and side surface 59 of the recess 53). Regardless of the position of the lure 31, the light emitting material 51 or the light (visible light) emitted by the light emitting material 51 can be seen from the outside of the lure 31.
[0040] Furthermore, even if the lure 31 (lure body 33) is brought into contact with a flat surface of an object (not shown), the bottom surface 57 and side surface 59 of the recess 53 recessed from the outer surface of the lure body 33 will not come into contact with the flat surface. The light-emitting material 51 provided in the recess 53 will also not come into contact with the flat surface.
[0041] Luminous materials absorb light energy such as ultraviolet light or visible light from the outside, store the energy (excite), and then convert the stored energy into visible light (excited light) to emit light. Luminous materials continue to emit light for a certain period of time even after the light source is cut off, making them particularly visible in dark places.
[0042] Fluorescent materials absorb external light energy, such as ultraviolet and visible light, convert it into light, and emit it. Fluorescent materials stop emitting light as soon as the light source is cut off.
[0043] The recess 53 is formed by a plurality of grooves 61 of a predetermined width. When viewed laterally, the surfaces 63 of the outer surface of the lure body 33 that are not formed with the plurality of grooves 61 and are located between the plurality of grooves 61 (for example, a plurality of surfaces surrounded by the plurality of grooves 61) are separated from each other in the front-rear and up-down directions. Furthermore, when viewed laterally, the plurality of surfaces 63 are aligned in the front-rear and up-down directions.
[0044] Furthermore, each of the multiple grooves 61 extends along the outer surface of the lure body 33, spaced apart from one another and intersecting with one another. Alternatively, each of the multiple grooves 61 may extend along the outer surface of the lure body 33, spaced apart from one another and substantially parallel to one another. Furthermore, the groove 61 shown in Figure 6 extends in a curved manner, such as in an arc shape.
[0045] The surfaces 63 of the outer surface of the lure body 33 that are not formed with multiple grooves 61 and are located between multiple grooves 61 can be said to be convex portions (convex surfaces) 63 that protrude further than the bottom surfaces 57 of the grooves 61, assuming that the bottom surfaces 57 of the grooves 61 are the reference surface. The convex portions 63 have roughly congruent shapes, and roughly similar shapes to each other. The convex portions 63 also form part of the outer surface of the lure body 33.
[0046] When the lure 31 (lure body 33) is viewed in the horizontal direction (a direction perpendicular to the plane of FIG. 6), the area of the convex portion 63 is larger than the area of the grooves 61. However, when the lure 31 is viewed in the horizontal direction, the area of the convex portion 63 may be smaller than the area of the grooves 61.
[0047] 7(b), the light-emitting material 51 is provided not only in the recess 53 but also on the convex surface 63. That is, the light-emitting material 51 is in the form of a film, and covers not only the bottom surface 57 and side surface 59 of the recess 53 but also the convex surface 63.
[0048] As shown in Fig. 7(b), the lure 1 is provided with a light-blocking material 65 (a light-blocking material that blocks visible light emitted by the light-emitting material 51). The light-blocking material 65 is provided on the convex surface 63. The light-blocking material 65 is applied in the form of a film and is provided on the light-emitting material 51 covering the convex surface 63. Although not shown in Fig. 7(b), a water-repellent material 35 is provided so as to cover the light-blocking material 65 and the light-emitting material 51 in the groove 61.
[0049] The artificial lure 31 will be explained in more detail. The artificial lure 31 shown in Fig. 6 is, for example, an egi used for squid fishing. The egi 31 looks like a spindle-shaped small fish, but it also looks like a small shrimp.
[0050] The lure body 33 is made of synthetic resin or wood. The outer diameter of the lure body 33 (the area of the cross section taken along a plane perpendicular to the front-to-rear direction, which is the left-right direction in Figure 6) gradually changes in the front-to-rear direction. That is, the outer diameter is small at the front end, gradually increases toward the rear, and is greatest at the center in the front-to-rear direction. The outer diameter of the lure body 33 also gradually decreases from the center toward the rear in the front-to-rear direction. The outer diameter at the front end of the lure body 33 and the outer diameter at the rear end are approximately equal to each other.
[0051] Furthermore, the lure body 33 has a slightly curved central axis extending from the center of the front end (left end in Fig. 6) of the lure body 33 to the center of the rear end (right end in Fig. 6) of the lure body 33. This curve makes the lure body 33 (lure 31) look like a small shrimp.
[0052] The front part of the lure body 33 forms the head, and the rear part of the lure body 33 forms the body. The dimension of the head in the front-to-back direction is smaller than the dimension of the body in the front-to-back direction. For example, the dimension of the body in the front-to-back direction is about three times the dimension of the head in the front-to-back direction. The recessed part 53 (groove 61) and the convex part 63 are provided in the body. More specifically, the recessed part 53 and the convex part 63 are provided over almost the entire body.
[0053] A line eye 67 protrudes slightly forward from the front end of the head of the lure body 33. A plurality of (for example, two) rear hooks (hooks) 69 protrude rearward from the rear end of the body. The two rear hooks 69 are connected in series.
[0054] The groove 61 is formed by a plurality of semicircular arc-shaped grooves (grooves that appear semicircular when viewed horizontally) 61 of a predetermined width that are lined up and connected in the front-rear and up-down directions. As a result, when viewed horizontally, the convex surface portion 63 has a fan shape with a central angle of approximately 90°, and the plurality of convex surface portions 63 are lined up vertically and up-down. Note that, because the groove 61 is formed in a semicircular arc shape, the two radii of the fan shape of the convex surface portion 63 are arc-shaped rather than straight. Furthermore, in the fan shape of the convex surface portion 63, a point corresponding to the central angle of the fan shape is located on the front side, and a point corresponding to the arc of the fan shape is located on the rear side. Note that the point corresponding to the central angle of the fan shape may be located on the rear side, and the point corresponding to the arc of the fan shape may be located on the front side.
[0055] In Figure 7(b), the cross-sectional shape of groove 61 (the cross-sectional shape of a plane perpendicular to the extension direction of groove 61) is rectangular, but the cross-sectional shape of groove 61 may be other shapes such as semicircular, arcuate, triangular, trapezoidal, etc.
[0056] The luminous material 51 is in the form of a thin film, and as shown in Figure 7(b), is integrally formed on the lure body 33 so as to cover the bottom surface 57 of the groove 61, the side surface 59 of the groove 61, and the entire surface of the convex portion 63.
[0057] The light-blocking material 65 is in the form of a thin film and is integrally provided on the lure body 33 so as to cover the entire surface of the light-emitting material 51 provided on the convex portion 63, but is not provided on the light-emitting material 51 provided on the bottom surface 57 of the groove 61 and the side surface 59 of the groove 61.
[0058] Here, the spray direction of the light-shielding material 65 when the light-shielding material 65 is provided on the lure body 33 provided with the light-emitting material 51 will be explained. First, as shown by arrow A1 in Fig. 7(a), the light-shielding material 65 is sprayed a first time toward the lure body 33 from an oblique direction (for example, from above the lure body 33 at an oblique direction). After the light-shielding material 65 provided on the lure body 33 by the first spraying has hardened, the light-shielding material 65 is sprayed a second time toward the lure body 33 from an oblique direction (for example, from below the lure body 33 at an oblique direction) as shown by arrow A2 in Fig. 7(b).
[0059] In the above description, the light-blocking material 65 is provided with the spray direction of the light-blocking material 65 at an angle. Alternatively, after the light-emitting material 51 is provided on the bottom surface 57 of the groove 61, the side surface 50 of the groove 61, and the surface of the convex surface portion 63, the concave portion 53 may be masked and the light-blocking material 65 may be provided, or the light-blocking material 65 may be provided on the light-emitting material 51 of the convex surface portion 63 using a brush or the like, while avoiding the concave portion 53.
[0060] In the lure 31, after the luminous material 51 and the light-blocking material 65 are provided on the lure body 33, the water-repellent material 35 is provided so as to cover the luminous material 51 and the light-blocking material 65. The water-repellent material 35 is designed to allow light absorbed by the luminous material 51 and light emitted by the luminous material 51 to pass through. As mentioned above, the water-repellent material 35 is not shown in Figure 7(b), but in reality, the water-repellent material 35 covers the entire surface of the light-blocking material 65 and the entire surface of the luminous material 51 in the groove 61.
[0061] 7(c), the grooves 61 may be formed shallowly and filled with the luminescent material 51, eliminating any recesses on the surface of the lure body 33. The entire surface of the lure body 33, including the luminescent material 51, may then be covered with the water-repellent material 35.
[0062] The squid jig 31 shown in Figure 7 is provided with parts 71 corresponding to eyes and a sinker 73. The entire surface of the sinker 73 may be covered with a water-repellent film. Also, instead of or in addition to providing the sinker 73 in the squid jig 31, a weight (not shown) may be provided inside the lure body 33.
[0063] The portion 71 corresponding to the eyes of the squid jig 31 is illuminated by, for example, an LED. Also, the portion designated by reference numeral 75 in FIG. 7 is a portion where feathers or the like (not shown) are attached. The portion 75 is formed, for example, as a cylindrical recess or a cylindrical protrusion. The feathers or the like attached to the portion 75 are positioned outside the squid jig 31. By attaching the feathers or the like, the functionality of the squid jig 31 can be further improved. It is desirable that the portion 71 corresponding to the eyes and the sinker 73 are also covered with the water-repellent material 35.
[0064] The lure 31 is comprised of a lure body 33 having a recess 53 on its outer surface, and a light-emitting material 51 provided in the recess 53. The light-emitting material 51 is contained within the recess 53 without protruding from the outer surface of the lure 31. This prevents the light-emitting material 51 in the recess 53 from coming into contact with other objects, even if the lure 31 collides with or rubs against other objects. This prevents damage to the light-emitting material 51 when the lure 31 collides with or rubs against other objects.
[0065] Furthermore, the lure 31 has a recess 53 provided in the lure body 33, and the luminous material 51 is provided in the recess 53. The luminous material 51 emits light, giving the lure 31 a three-dimensional appearance, which further improves its function of attracting fish and the like to bite.
[0066] Furthermore, in the lure 31, the recessed portion 53 is formed with a plurality of grooves 61. This allows the lure 31 to have a plurality of long, band-like light-emitting areas, making it easier to ensure the brightness of the light emitted by the lure 31. Furthermore, in the lure 31, the plurality of convex portions 63 are formed at a distance from each other, which also creates a three-dimensional effect.
[0067] Furthermore, in the lure 31, each of the multiple grooves 61 extends along the outer surface of the lure body 33, spaced apart from each other and intersecting with each other. This forms convex portions 63 that are arranged at predetermined intervals in the front-to-back and up-to-down directions. These convex portions 63 look like scales, further enhancing the functionality of the lure 31.
[0068] Furthermore, in the lure 31, the luminous material 51 is also provided on the convex portion 62 on the outer surface of the lure body 33, and the luminous material 51 provided on the convex portion 63 is covered with a light-blocking material 65 that does not transmit light. This eliminates the need to provide the luminous material 51 only in the recessed portion 53, which is recessed and therefore difficult to install, and makes the lure 31 easier to manufacture.
[0069] To explain further, the luminous material 51 is simultaneously applied to both the recessed portion 53 and the convex portion 63 of the lure body 33, and after the luminous material 51 has hardened, the shading material 65 can be applied by spraying it obliquely onto the luminous material 51 covering the convex portion 63, so that the shading material 65 can be easily applied.
[0070] The light emitting material 51 provided in the recessed portion 53 glows in the dark, and the visible light emitted by the light emitting material 51 provided in the convex portion 63 is blocked by the light blocking material 65, so that the convex portion 63 does not glow in the dark.
[0071] The surface of the light-blocking material 65 of the convex portion 63 (light-blocking material covering the light-emitting material 51 provided on the convex portion 63) is configured to reflect visible light. That is, the light-blocking material 65 of the convex portion 63 functions as a reflecting material. Note that the surface of the light-blocking material 65 of the convex portion 63 may be configured to reflect almost no visible light.
[0072] The reflectance of the light-blocking material 65 provided on the plurality of convex surface portions 63 may be different from one another. For example, the reflectance of the light-blocking material 65 may be high on the front side and gradually decrease toward the rear side, or vice versa. The reflectance of the light-blocking material 65 may be high on the upper side and gradually decrease toward the lower side, or vice versa. Furthermore, the reflectance of the light-blocking material 65 may be configured to change in both the front-to-rear direction and the up-and-down direction (up-and-down direction on the plane of the paper in FIG. 7).
[0073] In addition, the brightness of the luminescent material 51 provided in the recess 53 may change in the same manner as the reflectance of the light-blocking material 65, or the color of the luminescent material 51 provided in the recess 53 may change in the same manner as the reflectance of the light-blocking material 65.
[0074] Incidentally, the lure 31 shown in Fig. 6 may be provided with a sheet-like material (for example, cloth) not shown. The sheet-like material is provided on the lure body 33 and covers at least a part of the lure body 33. In this case, the sheet-like material is also provided with a water-repellent material 35. In other words, the water-repellent material 35 is provided so as to cover the surface of the sheet-like material.
[0075] To explain further, the water-repellent material 35 covers, for example, almost the entire surface of the lure body 33 and the entire sheet-like material. The water-repellent material 35 may be provided on the sheet-like material rather than on the lure body 33. The sheet-like material is provided on the lure body 33 by, for example, being wrapped around it. The water-repellent material may be provided on the sheet-like material after the sheet-like material is provided on the lure body 33.
[0076] In the lure 31, the surface of the sheet-like material (for example, cloth) covering the lure body 33 is covered with a water-repellent material 35. This makes it possible to easily change the shape of the lure 31 by changing the cloth, and also reduces water resistance when moving through the water.
[0077] When the lure 31 shown in FIG. 6 is provided with a sheet-like material provided with the water-repellent material 35, it is desirable to eliminate the recessed portion 53 (groove 61), the light-emitting material 51, and the light-blocking material 65.
[0078] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
