DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing uki (hereinafter referred to as "uki") and a fishing underwater uki (hereinafter referred to as "uki").
It is called "Underwater uki". More specifically, the present invention relates to a uki and an underwater uki that can prevent the ukiki body from being hydrated during use.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 10, there has been used a hook 7 of a type in which a fishing line (nylon line or the like) 61 is vertically inserted. As this type of uki 7
There is known an arrangement in which a tubular body for a starting material such as soft vinyl chloride is disposed in a through hole provided along a vertical direction.
However, in this type of horse 7, the fishing line 61 inserted through the tubular body has poor slippage, and a shimori ball is often required. In particular, in the case where a thread groove-like scratch is generated on the tubular body due to friction, the slip tends to be further deteriorated. Also,
When it is desired to fix the uki 7 to a desired portion of the fishing line 61, a toothpick T or the like is often inserted into the through hole.
In many cases, this fixation cannot be performed sufficiently due to the occurrence of thread groove scratches. The inventor of the present invention has tried to solve these problems, as shown in FIGS. 11 (a) and 11 (b).
Japanese Patent Publication No. 6-29973 has proposed a hook 8 in which a predetermined ring-shaped portion 82 is arranged at the upper end and the lower end of the device 1.

[0003]

According to this uki 8,
The fishing line 61 to the tubular body 83 for the fire is improved, and the above-mentioned disadvantages can be effectively solved. However, there is room for further improvement in the fire 8. That is, at least at the lower end side (there may be both upper and lower ends) of the arm 8, the ring-shaped portion 82.
When, and gap [FIG 11 (a) see] S ₂₀ communicating with the through hole 811 between the lower end of the float for the tubular body 83, the exposed surfaces [FIG 11 (b) refer] M caused to the through hole 811 Sometimes. Therefore, when the uki 8 is used for a long time, moisture permeates into the uki main body 81 from the gap S and the surface M, and the weight of the uki main body 81 increases, and the performance of the uki 8 may be impaired. Specifically, although the fish is not hooked, the uki main body 81 sinks more than necessary, and it is often impossible to sufficiently determine the presence or absence and degree of the hit. In particular,
In the case of sea fishing, since salt water with strong permeability is targeted,
Moisture seepage into the uki body 81 becomes faster. Further, if the wooden uki body is made of paulownia, the specific gravity is as small as about 0.2, so that the wooden uki has a large buoyancy and excellent uki performance, so that the paulownia uki body is often used. However, this has the disadvantage that the water absorption (water penetration) is large and the specific gravity becomes large by use.

In addition, moisture may permeate into the uki body 81 from around the opening ends of the through holes 811. Therefore, in order to use the umbrella 8 constantly and under good conditions, it is important to avoid long-term continuous use and appropriately dry it. Regarding these points, the same applies to the conventional uki except the uki 8 and the type of uki used in a state of being immersed in water as shown in FIG.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a uki and an underwater uki which have a good thread slippage, are unlikely to cause a yarn flaw, and can prevent the oyster body from containing water during use. The purpose is to:

[0006]

According to a first aspect of the present invention, there is provided a uki body having a through hole provided along a vertical direction;
A tubular body for an uki which is closely inserted into the through-hole and has an upper large-diameter portion with an enlarged inner diameter at the upper end, and a lower large-diameter portion with an enlarged inner diameter at the lower end. A substantially cylindrical shape having a front surface made of ceramic and having an outer peripheral side surface which can be closely and concentrically inserted into the upper large-diameter portion, and an inner peripheral surface whose inner diameter becomes smaller toward a substantially central portion along the vertical direction. And an upper ring-shaped portion closely inserted into the upper large-diameter portion, and at least a surface side made of ceramic, and an outer peripheral side which can be closely and concentrically inserted into the lower large-diameter portion; A lower ring-shaped portion having an inner peripheral surface whose inner diameter becomes smaller as it goes to a substantially central portion along the lower ring-shaped portion, and an outer wall portion of the uki main body; At least the outer wall portion of the inside of the through-hole on both ends of the opening Made is, epoxy resin, urethane tree
And a waterproof coating made of oil or acrylic resin .

In the present uki, since each ring-shaped portion is inserted into the tubular body for the uki, water does not permeate into the uki body from around each ring-shaped portion. In addition to this, the waterproof coating portion closes the boundary between the tubular tubular body and the tubular body (a very small gap is formed in the shape of the outer peripheral side surface of each ring-shaped portion). Therefore, it is possible to prevent water from seeping into the uki body from around the opening end. In addition, if the entire length of the tubular body for the uki is substantially equal to or longer than the entire length of the through-hole, if the waterproof coating portion is formed on the outer wall portion of the uki body, this boundary may be closed. Becomes On the other hand, if the entire length of the tubular tubular body is shorter than the entire length of the through-hole, a waterproof coating film that reaches each end of the tubular tubular body is provided inside both openings of the through-hole. Part will be formed.

Further, in the present uki, each of the above-mentioned ring-shaped portions is provided at the upper and lower ends of the tubular member for the uki, and the inner diameter of these ring-shaped portions becomes smaller toward the center. It has a surface. That is, the inner peripheral surface has a rounded curved surface shape (see FIGS. 2 and 3 and the like). Accordingly, by the action of these ring-shaped portions, a predetermined fishing line can be smoothly inserted from the upper end to the lower end of the tubular tubular body. In addition, since at least the surface side of each ring-shaped portion is made of ceramic, the strength is excellent, and even if there is contact with a fishing line, a line groove-shaped scratch is unlikely to occur. Also, even if it is used for a long time in salt water,
Deterioration and cracking are unlikely to occur. For this reason, the surface side of each ring-shaped portion is always in a smooth state, and the thread can slide smoothly, and the above-mentioned "fixation by toothpick or the like" can be reliably performed.

Further, since each ring-shaped portion has an outer peripheral side surface which can be closely inserted into a corresponding large-diameter portion, these ring-shaped portions are substantially adhered to the upper and lower ends of the tubular tubular body. , Can be fixed firmly. For this reason, even if this uki is repeatedly used, these ring-shaped portions are unlikely to fall out of the tubing tubular body. In addition, since each ring-shaped portion is closely inserted into each large-diameter portion, each ring-shaped portion is
It does not enter the intermediate portion of the tubular tubular body (see the second and third inventions). As described above, according to the present uki, it is possible to prevent the uki main body from being hydrated (immersed) at the time of use, and it is easy to use because the thread is good and the yarn is hardly damaged.

The outer shape of the "uki body" is variously selected.
For example, various shapes such as a substantially elliptical spherical shape (including a substantially acorn shape, a substantially rugby ball shape, and the like), a substantially spherical shape, a substantially trumpet shape, a substantially rice ball shape, and the like can be exemplified. In addition, examples of the material include various materials such as wood (for example, paulownia), plywood, resin, and resin foam. In particular, in consideration of the fact that the present invention is advantageous in effectively preventing the ingress of water into the uki body, this material is preferably made of wood or the like which is submerged as shown in the fourth invention. The wooden body may be the entire uki body or a part thereof (for example, one of the upper and lower sides). As a combination in the latter case, there is a case where the upper side is made of foamed resin and the lower side is made of wood having a specific gravity greater than that of the foamed resin. Further, the wooden portion (including both the whole and a part thereof) may be a combination of different materials. As this combination, the lower part can be made of wood with a large specific gravity, and the upper part can be made of wood with a small specific gravity. As the ceramic constituting at least the surface side of each of the ring-shaped portions, a ceramic which can sufficiently withstand the friction of the fishing line is selected. For example, silicon carbide, silicon nitride, sialon, alumina, mullite, cermet and the like can be exemplified. Among them, it is particularly preferable to use silicon carbide, silicon nitride or sialon. This is because these ceramics have particularly high strength and excellent wear resistance.

[0011] As described above, the total length of the "tubular body for uki" is
Even if it is almost equal to the total length of the through hole,
It may be shorter than this. The material of the "tubular body for uki" is not particularly limited, and may be made of resin, metal, ceramics, wood (especially impregnated with resin and impermeable to water), and the like. Can be selected. In particular, because of ease of processing and high corrosion resistance,
As shown in the fourth invention, it is preferable to use resin (hard vinyl chloride, engineering resin, etc.). In this case, by using a predetermined resin raw material, a tubular body for uki having large diameter portions at both ends may be formed, or a tubular body not having such large diameter portions (made of resin, metal, etc.). After forming and working, the both ends may be cut with a drill or the like to form each large diameter portion. As the waterproof coating unit, e
Epoxy resin, urethane resin or an acrylic resin coating film
No. However, when the design of the uki body itself is high, it is desirable that the waterproof coating portion be transparent. Also, a predetermined paint may be applied on the waterproof coating. Further, when the waterproofness of the paint is sufficient, the paint film for waterproof may be formed only by the paint. The waterproof coating film has not only a waterproof property but also an effect of protecting the surface (such as being hardly damaged) or improving the appearance. Therefore, in the present invention, this waterproof coating portion is used not only in the case where the main purpose is waterproofing, but also in the meaning including a coating portion formed mainly for the purpose of protecting the surface or improving the appearance.

In the second aspect of the present invention, the minimum inner diameter of the upper ring-shaped portion is an intermediate portion (hereinafter, referred to as a "tubular tube for the uki") between the upper large diameter portion and the lower large diametric portion of the tubular tubular body. The inner diameter of the lower ring-shaped portion is larger than the inner diameter of the lower ring-shaped portion. In the present invention, since the diameter increases in the order of the minimum inner diameter of the upper ring-shaped portion, the inner diameter of the middle portion, and the minimum inner diameter of the lower ring-shaped portion, the fishing line can be efficiently inserted from the upper end to the lower end of the tubular tubular body. It can be carried out.

In the third aspect of the present invention, the inner diameter of the intermediate portion of the tubular tubular body is tapered so as to gradually expand from above to below, and the minimum inner diameter of the upper ring-shaped portion is equal to that of the intermediate portion. The inner diameter of the lower ring-shaped part is made smaller than the inner diameter of the lower part of the intermediate part. In the present invention, since the inner diameter of the intermediate portion is tapered, the fishing line can be inserted more efficiently than in the second invention.

The minimum inner diameter of the upper ring-shaped portion is usually larger than the thickness of the fishing line to be used, and the outer diameter of the retaining portion disposed at a predetermined position of the fishing line (closer to the rod than the uki). (Size). If the outer diameter of the retaining portion is larger than the outer diameter of the retaining portion, the retaining portion enters the upper ring-shaped portion, and the retaining portion cannot perform the retaining effect. In many cases, the anti-floating portion is formed by threading and hardening with an adhesive, and its outer diameter is usually about 1.5 to 1.8 mm. Therefore, the minimum inner diameter of the upper ring-shaped portion is usually 0.5 to 1.5 mm.
(Preferably about 0.7 to 1.2 mm). Also, if the minimum inner diameter of the lower ring-shaped portion is too small, the slip of the fishing line will be poor, and if it is too large, if you want to fix the present uki on a desired part of the fishing line, insert a toothpick etc. into the through hole and fix it. It becomes difficult. Therefore, usually, the minimum inner diameter of the lower ring-shaped portion is about 1.8 to 2.5 mm (particularly about 2.0 to 2.4 mm), and is usually larger than the inner diameter of the middle part of the tubular body. I do.

In the fifth aspect of the present invention, the lower end portion of the tubular tubular body for uki and the lower ring-shaped portion are surrounded by a ring-shaped or cylindrical metal weight. The metal weight mainly adjusts the buoyancy of the snow. In particular, it is suitably used when the uki body is made of a material having a low specific gravity, such as wood or resin foam. In addition, as a constituent material of the metal weight, brass, lead and the like can be exemplified. Also,
When the metal weight portion is exposed on the outer wall side of the uki body, there will be a slight gap between the weight portion and the uki body, but this gap is also defined by the waterproof coating portion. Can be sealed.

In the sixth aspect of the present invention, at least the lower portion of the uki body is composed of a plurality of thin plates laminated and bonded so as to display a substantially woodgrain pattern. In the present invention, it is mainly intended to improve the beauty of the uki. In particular, if the thin plates are colored in various colors and the adjacent thin plates are colored differently, the appearance is further improved. Further, the portion constituted by the plurality of thin plates bonded and laminated may be the entire uki body or only a lower portion (for example, a lower half portion).

In the seventh invention, the lower part of the uki body is
It is composed of a plurality of thin plates laminated and bonded so as to display a substantially woodgrain pattern, and the remainder of the uki body is composed of a predetermined resin foam. The present invention, like the sixth invention, mainly intends to improve the beauty of the uki. Further, since the lower portion is formed by laminating thin plates with an adhesive, the specific gravity of the lower portion is slightly higher (for example, about 0.8) depending on the specific gravity and the amount of the adhesive used for the lower portion. It may be. According to the present invention,
In such a case, the remaining portion is made of a resin foam having a small specific gravity (for example, 0.15 or less in the case of urethane foam), so that the buoyancy of the whole uki can be easily adjusted.

An underwater uki according to an eighth aspect of the present invention includes an underwater uki main body having a through-hole provided along a vertical direction, an outer tubular body provided at an intermediate position between the through-holes, A lower large-diameter portion, which is disposed inside and has upper and lower ends protruding outside the underwater body, has an upper large-diameter portion having an enlarged inner diameter at an upper end portion, and has an enlarged inner diameter at a lower end portion. And a rubber or soft resin made of rubber or soft resin disposed so as to fill a space formed by the underwater broom body, the outer tubular body, and the inner tubular body, and to cover the inner protruding portion. A tubular cushion material, at least the surface side of which is made of ceramic, and an outer peripheral side that can be closely and concentrically inserted into the upper large-diameter portion, and an inner peripheral surface whose inner diameter becomes smaller as it goes to a substantially center along the vertical direction. And has a large upper diameter. An upper ring-shaped portion which is in close contact inserted, together with at least the surface side is made of a ceramic, an adhesion insertable outer peripheral surface substantially concentrically in the lower large-diameter portion,
A lower ring-shaped portion having a substantially cylindrical shape having an inner peripheral surface whose inner diameter becomes smaller as it goes to a substantially central portion along the vertical direction, and a lower ring-shaped portion closely inserted into the lower diameter large portion; And a waterproof coating formed on the outer wall of the main body. And also in this underwater uki, as shown above, the whole or a part of the underwater uki body can be made of wood, and the inner tubular body can be made of resin.

In this underwater uki, the inner tubular body (the first to seventh tubes)
This corresponds to the tubular body of the invention. ) Is surrounded by an outer tubular body and a tubular cushion material. Therefore, the underwater uki main body is substantially completely sealed from the inside of the inner tubular body. In addition, the waterproof coating can seal not only the underwater body but also the gap between the tubular cushion material and the underwater body. Therefore, in this underwater uki, the first
Water content of the underwater uki body can be sufficiently prevented in the same manner as the uki of the present invention. Further, since the inner tubular body, the upper ring-shaped portion, and the lower ring-shaped portion having the same structure as that of the first invention and the tubular body for the sea are provided, the fishing line can be easily inserted. In particular, if the inner tubular body has a tapered shape similar to that of the third aspect of the present invention, the insertion is further facilitated. Further, the inner diameter of the tubular cushion material arranged above is made smaller than the minimum inner diameter of the upper ring-shaped part, and the inner diameter of the tubular cushion material arranged below is made larger than the minimum inner diameter of the lower ring-shaped part. This further facilitates this insertion.

[0020] The underwater umbrella also exerts the following effects. That is, as shown in FIG.
Is generally used together with the floating uki 87 (normal uki). When the conventional underwater umbrella 88 is pulled out of the water, the underwater umbrella 88 often hits the floating umbrella 87, the monkey ring (Swivel) K, or the like, or the rock. For this reason, the through-hole provided in the underwater umbrella 88 often collapses, and the underwater umbrella main body often cracks, breaks, and the like. On the other hand, in order to avoid these, it is also possible to arrange a rubber-made, tubular cushion material between the levitating seam 87 and the underwater seam 88 or between the underwater seam 88 and the ring K. Become. However, in this case, it is necessary to pass a thin thread through these cushion materials, which is troublesome. In particular, when fishing in the cold winter, the hands are stiff and difficult. Further, even if such a cushion material is used, it is not possible to avoid collision of the underwater balloon 88 with the rock. Further, the monkey ring K enters the cushion material, and as a result, the submerged water 88 and the monkey ring K collide with each other, often damaging the through hole and the submerged water main body.

On the other hand, in the present invention, since both ends of the inner tubular body protrude up and down of the underwater body and each of the tubular cushion members covers the projecting portion, the other tubular cushion members than the respective tubular cushion members are covered. Part is another uki (floating uki),
It is unlikely to directly hit the monkey ring or rock. For this reason, problems due to the above collisions are prevented. Also,
Each cushion material itself constitutes a part of the underwater umbrella and is integrated from the beginning, so that it is easy to handle. In addition, since the inner tubular body has a double-tube structure and has a protruding portion, there is no problem such as that the monkey ring gets into the tubular cushion material.

[0022]

Embodiments of the present invention will be described below. (1) Embodiment 1 In the present embodiment, the uki U ₁ shown with reference to FIGS.
Is described. This uki U ₁ is, as shown in FIG.
Uki body 11, tubular body 12, upper ring-shaped portion 13
, A lower ring-shaped part 14, a weight part 15, and a waterproof coating part 16.

Of these, the uki body 11 is made of paulownia and has an acorn-like elliptical spherical shape (length: 40 to 50 mm, maximum diameter: about 20 to 35 mm) as a whole. In the center, a through-hole (hole diameter: about 4.1 mm) penetrated in the vertical direction
φ) 111 is provided. The tubular body (outer diameter: about 4.0 mmφ, inner diameter: about 2.0 mmφ) 12 is made of hard vinyl chloride, and is disposed in close contact with the through hole 111. The two open ends of the tubular body 12 are in contact with the outer surface of the uki body 11 (not projecting). The tubular body 12 has a tapered shape in which the inner diameter gradually increases toward the lower end, and has a structure convenient for thread insertion.

The upper end of this tubular body 12 is
As shown in the figure, the upper part of the upper diameter (the inner diameter;
(About 3.3 mmφ) 121 is provided. Furthermore, a lower-diameter large portion (inner diameter: about 3.5 mmφ) 122 as shown in FIG. As shown in FIGS. 4 (a) and 4 (b), these large-diameter portions 121 and 122 are formed by drilling each open end side of the tubular body 12 with a drill larger than the inner diameter of the tubular body 12 [FIG. (See broken line). Therefore, each large diameter portion 121,
Each of the reference numerals 122 has a vertical cross section in the shape of an equilateral trapezoid. However, assuming that the tubular body 12 has such large-diameter portions (the longitudinal section may have an isosceles trapezoidal shape or another shape such as a substantially rectangular shape) 121 and 122 at both ends. , May be integrally formed.

Further, the upper ring-shaped portion (outer diameter: about 3.2 m)
mφ, minimum inner diameter; 0.8 mmφ, thickness along the up-down direction; about 1 mm) 13 is made of a silicon carbide material. Then, it is tightly inserted (using an instantaneous adhesive) concentrically with the tubular body 12 at a cylindrical space portion which is a main portion of the upper large-diameter portion 121. The inner diameter of the ring-shaped portion 13 becomes smaller toward the center.
φ) is the inner diameter of the intermediate portion 123 of the tubular body 12 (about 2.0 m
mφ) or less.

The lower ring-shaped portion (outer diameter: about 3.4 m)
mφ, minimum inner diameter; about 2.2 mmφ, thickness along the vertical direction; about 1 to 1.5 mm) 14 is also made of a silicon carbide material. Then, it is closely inserted (using an instantaneous adhesive) concentrically with the tubular body 12 at a cylindrical space portion that is a main portion of the large-diameter portion 122 on the lower side. This ring-shaped part 14
The inner diameter becomes smaller toward the center, and the minimum inner diameter (about 2.2 mmφ) is equal to the inner diameter (about 2.0 m) of the tubular body 12.
mφ). The ring-shaped portion 14
Is bonded and fixed using the tubular body 12 and a weight portion 15 described below and an instant adhesive.

The metal (brass) weight 15 (length 5)
-20 mm) is embedded in the uki body 11 so as to cover the lower end portion of the tubular body 12. The weight and the like of the weight portion 15 are adjusted by the specific gravity of the material forming the uki body 11, the volume and shape of the uki body 11, the desired position of the waterline, and the like. In addition, the waterproof coating portion 16 is provided with the uki body 11.
Apply a transparent paint with waterproofness (for example, acrylic resin or urethane resin paint) to the outer surface of the
It is cured. As shown in FIGS. 2 and 3, the waterproof coating portion 16 is formed by the uki body 11 and the tubular body 1.
2 (very small gaps) S ₁ and S _2, and the gap between the uki body 11 and the weight portion 15 (very small gaps) S ₅
Is tightly sealed.

In the above-mentioned uki U ₁ , both ring-shaped portions 13,
14 is housed inside the tubular body 12. The gaps S _{1 to} S ₃ exposed on the outer wall side of the uki body 11, not to mention the main part of the uki body 11, are formed by the waterproof coating 16.
It is firmly covered with. For this reason, this book U ₁
Even if it is used for a long time, it is possible to sufficiently prevent the uki body 11 from containing water.

Each of the ring-shaped members 13, 1 made of silicon carbide
Since No. 4 is used, it has excellent strength, and does not easily produce thread groove-like scratches even when it comes into contact with nylon yarn. Therefore, the thread can be smoothly slid and the above-mentioned "fixation by toothpick or the like" can be surely performed. Each of the ring-shaped members 13 and 14 is shown in FIG.
And 3 (because it has a minimum inner diameter), the number of contact points with the fishing line is small, the resistance when the fishing line is inserted is small, and the thread Good. Moreover, the minimum inner diameter of the upper ring-shaped body 13 is smaller than the inner diameter of the intermediate portion 123 of the tubular body 12, and the minimum inner diameter of the lower tubular body 14 is larger than the inner diameter of the intermediate portion 123. It can be done smoothly. In addition, since the weight portion 15 is made of brass, the strength and impact resistance are superior to those made of lead, the insertion hole is not crushed, the center of gravity is stable, and the function as a back is excellent.

FIG. 5 shows a modification of this embodiment.
This will be described with reference to FIGS. FIG. 5 shows that the entire length of the tubular body 12 is shorter than the entire length of the through hole 111. For this reason, each open end of the tubular body 12 is
11 are retracted from the respective open ends. In this case, if the waterproof coating portion 16 is formed not only on the outer wall surface of the uki body 11 but also on the inside of the opening end of the through hole 11, the gap S between the tubular body 12 and the uki body 11 can be reduced. ₅ to
We can seal well. Also, contrary to FIG. 6, even when the entire length of the tubular body 12 is longer than the entire length of the through-hole 111, the waterproof coating portion 16 formed on the outer wall surface of the uki body 11 has In addition, the gap between the uki body 11 can be securely sealed.

FIG. 6 shows a case in which the metal weight 15 has a substantially cylindrical base 151 which goes around the lower open end of the tubular body 12. However, such a base 151 may be attached so as to protrude from the uki body 11 or may be attached so as to be embedded in the uki body 11. Further, a similar base (in the state of protruding from the uki body 11) around the opening end on the upper side of the tubular body 12,
It may be buried. ) Can also be attached.
Even in the case shown in FIG. 6, a metal weigh section 15, on the clearance S ₆ of the float body 11, if the waterproof coating 16 is formed can be sufficiently sealed. Further, from lifting U ₁ of the present embodiment may be omitted metallic weigh section 15.
In this case, it is preferable that the whole shape of the uki main body 11 be relatively round (a shape close to a sphere). This is because even if the overall weight is small, the position of the center of gravity is low, and thus the stability is high.

[0032] (2) float U ₂ forms two embodiments are those shown with reference to FIG. 7 (a) ~ (c), the material of the float body 31, the structure and appearance different, Except that the metal weight 15 is not provided, it is the same as the uki U1 of the _first embodiment. FIG. 7
As shown in the front view of (a), the float U ₂ is lower half 3
An annual ring pattern or a rainbow pattern in which semi-ellipses are arranged in parallel in front of 1b is formed. As shown in the side view of FIG. 7B, a straight-grained annual ring pattern is formed on the side surface of the lower half portion 31b. Furthermore, half 31a on the float U ₂ has a substantially white semi ellipsoid.

Next, a method of manufacturing this uki U ₂ will be described with reference to FIG.
This will be described briefly using (c). First, the upper half 31a
Is formed by forming an upper through-hole 311a in a substantially semi-elliptical spherical urethane foam (specific gravity: about 0.15). Even if the upper half portion 31a is formed into a substantially semi-elliptical sphere by using a predetermined mold, a lump of urethane foam having a predetermined shape is cut out to form the semi-elliptical sphere. There may be things. On the other hand, the lower part 31b is produced as follows. First, black, red,
Thin plate colored in each color of orange (thickness: 1 to 1.5 m
m) are prepared for each color. However, a thin plate without such coloring may be used, and the color of the colored thin plate is not limited to these three colors.

Next, each thin plate is immersed in an alcohol-based solvent, and the thin plate is impregnated with the solvent and dried. Furthermore, each thin plate is bonded with an adhesive (epoxy resin adhesive,
(Urethane resin-based adhesive or phenolic resin adhesive) is placed in a container, and the adhesive is impregnated into each thin plate. Then, the thin plates are laminated, and the laminate is pressed. At this time, the adhesive is dried by applying heat.
Furthermore, the lower portion 31b is completed by shaving the laminate into a semi-elliptical sphere and providing the lower through hole 311b. However, in the present embodiment, among the thin plates constituting the lower portion 31b, those adjacent to each other do not have the same color. That is, as shown in FIG. 7 (c), the lower portion 31b, is next placed a red sheet 31b ₂ of the thin plate 31b ₁ black, red next to orange sheet 31b ₃ is disposed in the sheet 31b ₂ And the orange sheet 31
sheet 31b ₁ next black of b ₃ are arranged, and further repeating this order. However, the color scheme is not limited to this.

Then, when the upper half 31a and the lower half 31b are connected, the uki body 31 is completed. At this time,
The upper through-hole 311a and the lower through-hole 311b communicate with each other to form a through-hole 311 of the entire uki body 31. Furthermore, the same tubular body 32 in the first embodiment, the placing upper ring-shaped portion 33 and the lower ring section 34, by performing the formation of the waterproof coating unit 36, the float U ₂ is completed.

The above-mentioned uki U ₂ is the uki U of the first embodiment.
It has the same functions as ₁ and the following functions.
First, in the float U _2, since the improvement in design property are achieved, it is possible to stimulate the willingness of consumers. In particular,
The design of the lower half part 31b which expresses a wood grain pattern or a rainbow pattern in three colors is high. Moreover, in spite of having such a high designability, it is excellent in that it is easy to manufacture and does not increase the manufacturing cost.

In the manufacturing process, the lower half portion 31b is soaked with an adhesive into a thin plate constituting the lower half portion 31b, and the specific gravity is increased, but the upper portion 31a is made of urethane foam having a small specific gravity. because it is composed Te, sufficient buoyancy can be obtained in the entire float U _2. Also, like this,
Since the specific gravity of the lower portion 31b itself increases, it is not necessary to use the metal weight portion 15 as shown in the first embodiment.

Further, an inner tubular body (length: about 25 mm, outer diameter: 4.0 mmφ, inner diameter: 2.0 mmφ) 52b is disposed inside the outer tubular body 52a. And
Both ends 521b and 522b protrude outside the underwater body 51. The projecting ends 521b, 522b
Is about 1 mm, but is not limited thereto. Also, this inner tubular body 52b is
The large-diameter portions 121 and 12 of the first embodiment are provided at the respective end portions.
2 has a large diameter portion similar to that of FIG. The upper ring-shaped portion 53 is similar to the upper ring-shaped portion 13 of the first embodiment, and the lower ring-shaped portion 53 is also similar to the lower ring-shaped portion 14 of the first embodiment. is there. Each of the large-diameter portions is mounted in the same manner as in the first embodiment.

Further, each tubular cushion material (length: about 4 to
6mm) 57a and 57b are predetermined soft resins (soft urethane resin, soft vinyl chloride resin, etc.) or rubbers (natural rubber, SBR rubber, EPR rubber, EPDM rubber, etc.)
It is a substantially cap-shaped member formed by using. The inner diameter of each of the tubular cushion members 57a and 57b is spread in a stepped manner at an intermediate point. That is, the upper tubular cushioning member 57a, upper inner diameter than the step portion D ₁ is the minimum inner diameter (approximately 0.8mm of upper ring-shaped portion 53
φ). Also, lower internal diameter than the step portion D _1, because they are approximately 41mm, part of the downward, is put on the upper end 521b of the inner tubular member 52b. Further, the lower tubular cushioning member 57 b, the lower of the inner diameter than the step portion D _2, are smaller than the minimum inner diameter of the lower ring-shaped portion 54 (approximately 2.2mmφ). Also,
Upper inner diameter than the step portion D _2, because they are approximately 41mm, the upper part, is put on the upper end 522b of the inner tubular member 52b.

Further, the weight portion (made of brass) 55 has a tubular weight portion 55 made of brass arranged and fixed on the bottom side of the underwater body 51 as in the first embodiment. The waterproof coating portion 56 is formed by applying a transparent paint (for example, an acrylic paint) having a waterproof property on the outer surface of the underwater uki body 51 and curing the paint. The waterproof coating portion 56 includes the underwater uki body 11 and the tubular cushion members 57.
a, a gap between 57b and (negligible clearance) S _10, S _11, an underwater float body 11, the gap S ₁₂ between the weigh section 55, and scolding cutting seal.

In the present underwater umbrella U ₃ , the outer side of the inner tubular body 52 b is connected to the outer tubular body 52 a and each tubular cushion 57.
a, 57b. Therefore, the underwater uki body 5
1 is in a state of being almost completely sealed from the inside of the inner tubular body 52b (water easily enters this portion). Also,
The waterproof coating unit 56, not only the main portion of the water float body 51, the gaps S ₁₀ ~ ₁₂ exposed to the outer wall side of the water float body 51 is sealed. Accordingly, the present water float U _3, during their long-term use, can be sufficiently prevented the water in water float body 51. In addition, even if the paulownia uki body (specific gravity: about 0.2), which usually has high water absorption, water absorption (water infiltration) is prevented, so that the magnitude of buoyancy can be maintained for a long time, and the uki performance is very poor. Excellent.

The inner tubular member 52b and the upper ring portions 53 and 54 are provided, and the inner diameter of the upper tubular member 57a is smaller than the minimum inner diameter of the upper ring portion 53. Since the inner diameter of the lower tubular cushion 57b is larger than the minimum inner diameter of the lower ring-shaped portion 54, it is easy to insert the fishing line.
If the inner tubular body 52b has a tapered shape similar to that of the tubular body 2 of the first embodiment, the insertion is further facilitated.

[0044] Moreover, in the underwater float U _3, the cushion material 57a, 57 b are protruded portion 521b, covers the 522b, the other parts, the other lifting (flotation float),
Since there is little direct collision with a monkey ring, rock, or the like, breakage, scratching, and collapse of the through-hole are less likely to occur.
Each cushion member 57a, is 57b itself constitutes a part of the underwater float U _3, since together from the beginning,
It is not necessary to perform a complicated operation of attaching a separate cushion material as in the related art. Underwater U
₃ is particularly convenient when used in the cold or in a dark place. Further, since the inner tubular body b has the double-tube structure and has the protruding portions 521b and 522b, for example, a monkey ring enters into the conventional cushion material, breaks the cushion material, and There are no drawbacks such as exposure of the underwater body and crushing of the through-hole of the underwater body 51.

Further, as a modified form of the embodiment, FIG. 9 (a), the exemplified water float U _5, such as shown in (b). This underwater float U ₅ is one that flows well to the water flow. In the underwater float U _5, as shown in FIG. 9 (a),
The outer shape of the underwater uki body 51c has a trumpet shape.
A ring-shaped brass weight portion 55c is provided at the base of the trumpet shape. The rest of the configuration is the same as underwater float U ₃ of the third embodiment.

The underwater umbrella U ₅ exhibits the following functions in addition to the function of the underwater umbrella U ₃ of the _third embodiment. That is, the water float U _5, together with a trumpet shape, the center of gravity is in the root. Therefore, when it was actually tested using this, the following effects and excellent effects were exhibited. First, when dropped into water first, it falls straight down in the vertical direction. Then, underwater, it rotates around this root in the direction of the water flow.

Then, as shown in FIG. 9 (b), the upper surface of the trumpet shape is directed in the direction of the water flow while having a certain angle in the direction of the water flow, so that the water is properly received. Then, at an angle of 30 to 45 degrees with respect to the vertical direction, the underwater umbrella starts to move along the flow for the first time. As described above, when the flow becomes strong and the underwater buds start to move, the underwater buds receive the water flow and the underwater buds move with a strong force. Along with this, the uki on the surface moves for the first time. Until then, the uki on the surface will not move. Thereby, the strength of the flow in the water, especially the flow behavior in the case of the double tide, the flow of the bait, and the like are well understood, which is convenient.

It should be noted that the present invention is not limited to the specific embodiments described above, but may be modified in various ways within the scope of the present invention in accordance with the purpose and application.
Other embodiments and modifications can be made. That is, the material of each of the uki main bodies 11, 31, 51, 51c is not limited to those shown in the respective embodiments. For example, each uki body 11,
The whole 31, 51, 51c may be made of wood (ebony or the like) other than paulownia, or may be made of resin (effective for backlighting), resin foam, or the like. Further, the uki bodies 51 and 51a of the third embodiment and its modified form may be made of the same material as the uki body 31 of the second embodiment. Furthermore,
The entire uki main bodies 31, 51, and 51c according to the second and third embodiments and the modified embodiments thereof may be formed of an adhesive laminate of a plurality of thin plates. In addition, each uki body 1
Each of 1, 31, 51, and 51c may be composed of a lower half of a wooden material such as paulownia wood and an upper half of a resin foam or the like.

Also, each uki body 11, 31, 51, 51
c may be appropriately colored. In particular, each uki body 1
If fluorescent paint is applied to the upper side of 1, 31, 51, 51c (especially, the upper side of the waterline), around the waterline, etc., it is convenient for night fishing. If the paint for coloring is highly waterproof, the paint film 16 and the like can be formed with the paint. Furthermore, when coloring is performed, it may be two or more colors. Further, each of the ring-shaped portions 1
The ceramic constituting the entirety or a part of the ceramics 3 and 14 may be any ceramic that can sufficiently withstand the friction of the fishing line, etc. In addition to silicon carbide, use silicon nitride, sialon, alumina, mullite, cermet, or the like. Can be. Among these, silicon carbide, silicon nitride or sialon is particularly preferred. It is because of high strength and excellent wear resistance. Further, as described above, the entire upper and lower ring-shaped portions may be made of this ceramic, or only the surface thereof may be coated with ceramic.

Each of the tubular members 12, 32, 52a,
The size (thickness, length, inner diameter, etc.), material, and the like of 52b and the like are selected depending on the purpose and the like. For example, as this material, in addition to polyvinyl chloride, various other resins (including engineering resins), and furthermore, metals and the like can also be used.
When this is a resin, the operation such as insertion is easy and inexpensive, and when it is a metal, it is strong against external impacts and can also serve as a weight. In addition, in the fishing and underwater uki of the present invention, a waterproof coating is formed on the outer wall portion. However, depending on the material of the uki body or the purpose of use, this waterproof coating may be used. The portion may not be formed. When the uki body is made of water-permeable wood, it is necessary to form the waterproof coating portion, but when the uki body is made of a water-impermeable resin,
Practical use is possible without this waterproof coating.
