Description

本発明は、魚釣りの際に使用される浮きに関する。 The present invention relates to a float used during fishing.

浮き釣りは、魚が餌に喰い付いたか否かを浮きの動きから判断する代表的な釣りの手法である。浮きは、魚の種類、釣る場所、仕掛け等に応じて種々の形態、大きさのものが市販されており、釣り人は、その中から適当なものを選択して使用する。代表的な浮きに棒浮き及び円錐浮きがある。 Float fishing is a typical fishing method that determines whether or not a fish has bitten a bait from the movement of the float. There are various types and sizes of floats on the market depending on the type of fish, fishing location, gimmicks, etc., and anglers select and use appropriate floats from them. Typical floats are rod floats and cone floats.

棒浮きは、縦長の棒状の浮きであり汎用性が高く、釣り糸（道糸）に固定して使用する固定浮き又は道糸に対して移動可能に取付け使用する遊動浮きとして使用される。棒浮きは、視認性がよく、小さなアタリでも目視し易い一方で、遠投性能が低く遠くに飛ばせない、また風に弱いという弱点がある。アタリは、魚が餌を突く、食い付くときに竿・浮きに表れる動きである。 The rod float is a vertically long rod-shaped float and is highly versatile, and is used as a fixed float used by being fixed to a fishing line (line) or a floating float that is movablely attached to the line. The stick float has good visibility and is easy to see even with a small hit, but it has the weaknesses that it has low long-distance casting performance and cannot be flown far, and it is vulnerable to wind. Atari is a movement that appears on a rod or float when a fish pokes or bites a bait.

円錐浮きは、一般的に紡錘形状を有し、浮き本体に上下方向に貫通する貫通孔を備え、貫通孔にラインを通す中通し浮きとして使用される。円錐浮きは、遠投性能に優れ、また風にも強い一方で、感度及び視認性が悪い、波が出るとアタリが分からないという弱点がある。 The conical float generally has a spindle shape, the float body is provided with a through hole penetrating in the vertical direction, and is used as a through hole for passing a line through the through hole. The conical float has excellent long-distance casting performance and is strong against wind, but has weaknesses such as poor sensitivity and visibility, and the fact that atari cannot be detected when waves are generated.

以上のような棒浮き、円錐浮きの長所を活かすべく、棒浮きと円錐浮きとを合体させた２重構造の浮きが提案されている（例えば特許文献１参照）。特許文献１に記載の２重構造の浮きは、中空の浮き本体の周囲に重りを取付け、中心部に貫通孔を設け、その貫通孔に棒状の浮子を通し、浮子の上下に玉浮子を設けたものである。 In order to take advantage of the above-mentioned advantages of rod float and conical float, a double-structured float that combines rod float and conical float has been proposed (see, for example, Patent Document 1). For the double-structured float described in Patent Document 1, a weight is attached around the hollow float body, a through hole is provided in the center, a rod-shaped float is passed through the through hole, and ball floats are provided above and below the float. It is a thing.

実用新案登録第３０００１０５号公報Utility Model Registration No. 3000105

特許文献１に記載の浮きは、浮力を得るために棒状の浮子の下部に大きな玉浮子を取付けている。このような構造では棒状の浮子が上下する際に、玉浮子が大きな抵抗となり、アタリに対する応答性が低下する。特許文献１に記載の浮き以外にも棒浮き及び円錐浮きそれぞれの長所を活かすべくこれらを合体させた浮きが提案されているが十分とは言い難い。 The float described in Patent Document 1 has a large ball float attached to the lower part of a rod-shaped float in order to obtain buoyancy. In such a structure, when the rod-shaped float moves up and down, the ball float becomes a large resistance and the responsiveness to atari is lowered. In addition to the floats described in Patent Document 1, floats that combine these floats to take advantage of the advantages of rod floats and cone floats have been proposed, but it is not sufficient.

従来の棒浮き及び円錐浮きは、それぞれ機能・性能を最大限発揮できるように検討工夫が重ねられ現在の形状・構造となっている。棒浮き及び円錐浮きは、それらを単独で使用することが前提で形状・構造が決められているためこれらを単純に組み合わせても形状・浮力のバランスなどが悪く優れた浮きとはならない。 The conventional rod float and conical float have the current shape and structure after repeated studies and ingenuity so as to maximize their functions and performances. Since the shapes and structures of rod floats and conical floats are determined on the premise that they are used alone, even if they are simply combined, the balance of shape and buoyancy is poor and the floats are not excellent.

本発明の目的は、アタリに対する応答性、遠投性能、投げたときのコントロール性などに優れる、使い勝手のよい魚釣り用浮きを提供することである。 An object of the present invention is to provide an easy-to-use fishing float having excellent responsiveness to atari, long-distance casting performance, controllability when thrown, and the like.

It is a figure. FIG. 4 is a cross-sectional view showing a state when the fishing float 1 according to the first embodiment of the present invention is thrown. Hereinafter, water and seawater are collectively referred to as water, and underwater and seawater are collectively referred to as underwater.

本発明の第１実施形態の魚釣り用浮き１は、貫通孔２０を備える外浮き１０と、貫通孔２０に上下動自在に取付けられた棒状の内浮き３０と、外浮き１０の姿勢を安定させる重り６０と、釣り糸１００を通す環７０とを備える。 The fishing float 1 of the first embodiment of the present invention stabilizes the posture of the outer float 10 provided with the through hole 20, the rod-shaped inner float 30 movably attached to the through hole 20 in the vertical direction, and the outer float 10. A weight 60 and a ring 70 through which the fishing line 100 is passed are provided.

外浮き１０は、内浮き３０を上下動可能に支持する水に浮く浮きである。外浮き１０は、入水抵抗・水中抵抗が小さく、また魚釣り用浮き１を投げたとき空気抵抗の小さい外観形状を有するものがよい。入水抵抗・水中抵抗を小さくするには、中央部から下端１７に向けて細くなる先細り形状がよく、投げたときの空気抵抗を小さくするには、中央部から上端１６に向けて細く湾曲した形状がよく、全体として流線型、涙滴型、紡錘型、卵型、円錐型又は角錐型の外観形状を有するものが好ましい。 The outer float 10 is a float that floats on water that supports the inner float 30 so as to be able to move up and down. The outer float 10 preferably has an external shape having a small water entry resistance / underwater resistance and a small air resistance when the fishing float 1 is thrown. To reduce the water entry resistance and water resistance, a tapered shape that tapers from the center to the lower end 17 is good, and to reduce the air resistance when throwing, a shape that is tapered from the center to the top 16 It is preferable to have a streamlined, teardrop-shaped, spindle-shaped, oval-shaped, conical or pyramidal-shaped appearance shape as a whole.

外浮き１０の代表的な寸法を示せば高さ（全高）Ｈ_０が３０～３５ｍｍ、最大直径部１５の位置（高さ）Ｈ_１が上端１６からＨ_１／Ｈ_０＝０．２５～０．３、最大直径部１５の径Ｄ_０が２０～２５ｍｍ、下端１７の直径Ｄ_１がＤ_１／Ｄ_０＝０．４５～０．５である。但し、本発明に係る魚釣り用浮きにおいて、外浮き１０は、この大きさ（数値）に限定されるものではない。 If the typical dimensions of the outer float 10 are shown, the height (total height) H ₀ is 30 to 35 mm, and the position (height) H ₁ of the maximum diameter portion 15 is from the upper end 16 to H ₁ / H ₀ = 0.25 to 0. 3. The diameter D ₀ of the maximum diameter portion 15 is 20 to 25 mm, and the diameter D ₁ of the lower end 17 is D ₁ / D ₀ = 0.45 to 0.5. However, in the fishing float according to the present invention, the outer float 10 is not limited to this size (numerical value).

外浮き１０の材質は、特に限定されるものではないが代表的には合成樹脂、木製であり、中実、中空構造であってもよく、所定の浮力となるように材質、構造を適宜選択すればよい。外浮き１０には、視認性を高めるために基本的に蛍光塗料が塗布されるためこの点も考慮して材質を決めることが好ましい。また外浮き１０の表面は、平滑であるのがよい。投げたときの空気抵抗を小さくすることができる。 The material of the outer float 10 is not particularly limited, but is typically synthetic resin or wood, and may have a solid or hollow structure, and the material and structure are appropriately selected so as to have a predetermined buoyancy. do it. Since a fluorescent paint is basically applied to the outer float 10 in order to improve visibility, it is preferable to determine the material in consideration of this point as well. Further, the surface of the outer float 10 should be smooth. The air resistance when throwing can be reduced.

外浮き１０は、中心部に縦方向に貫通する貫通孔２０を備え、ここに内浮き３０が上下動自在に挿通される。貫通孔２０は、上部に縮径部２１が設けられ、縮径部２１の下端が段差部２２となっている。貫通孔２０のうち縮径部２１を除く部分を第１孔２３、縮径部２１を第２孔２４とすると、第１孔２３の直径Ｄ_２は、内浮き３０の拡径部４３の直径ｄ_１よりも大きく、下端１７の直径Ｄ_１よりも小さい。第２孔２４の直径Ｄ_３は、内浮き３０の上部４２の直径ｄ_２よりも大きく第１孔２３の直径Ｄ_２よりも小さい。 The outer float 10 is provided with a through hole 20 penetrating in the vertical direction at the center thereof, through which the inner float 30 is inserted so as to be vertically movable. The through hole 20 is provided with a reduced diameter portion 21 at the upper portion, and the lower end of the reduced diameter portion 21 is a stepped portion 22. Assuming that the portion of the through hole 20 excluding the reduced diameter portion 21 is the first hole 23 and the reduced diameter portion 21 is the second hole 24, the diameter D ₂ of the first hole 23 is the diameter of the enlarged diameter portion 43 of the inner float 30. It is larger than d ₁ and smaller than the diameter D ₁ of the lower end 17. The diameter D ₃ of the second hole 24 is larger than the diameter d ₂ of the upper portion 42 of the inner float 30 and smaller than the diameter D ₂ of the first hole 23.

段差部２２は、内浮き３０のストッパー５０を係止させ、内浮き３０が上部方向に抜けることを防止する部位である。外浮き１０の段差部２２の位置は、外浮き１０の上端１６に近い方が好ましい。外浮き１０に対する内浮き３０の係止位置が高いほど安定する。 The step portion 22 is a portion that locks the stopper 50 of the inner float 30 to prevent the inner float 30 from coming off in the upper direction. The position of the step portion 22 of the outer float 10 is preferably close to the upper end 16 of the outer float 10. The higher the locking position of the inner float 30 with respect to the outer float 10, the more stable it is.

内浮き３０は、細長い円柱状（棒状）の浮き本体４１と上下方向の移動を規制するストッパー５０とからなり、外浮き１０に設けられた貫通孔２０に上下動自在に挿通される。本体４１は、中央に上部４２及び下部４４に比較して径の大きい縦長の拡径部４３を有する。本体４１の下部４４は、下端４６に向けて径が細い先細り形状を有し、正面視において僅かに外側に突出するように湾曲している。本体４１の下部４４を、下端４６に向けて先細り形状とすることで入水抵抗・水中抵抗を小さくすることができる。本体４１の上端４５は、球冠形状が好ましい。本体３１の上端４５を球冠形状とすることで、魚釣り用浮き１を投げたとき空気抵抗を小さくすることができる。 The inner float 30 is composed of an elongated cylindrical (rod-shaped) floating main body 41 and a stopper 50 that restricts movement in the vertical direction, and is inserted vertically into a through hole 20 provided in the outer float 10. The main body 41 has a vertically long diameter-expanded portion 43 having a larger diameter than the upper portion 42 and the lower portion 44 in the center. The lower portion 44 of the main body 41 has a tapered shape with a diameter narrowing toward the lower end 46, and is curved so as to slightly project outward in front view. By forming the lower portion 44 of the main body 41 into a tapered shape toward the lower end 46, the water entry resistance and the underwater resistance can be reduced. The upper end 45 of the main body 41 preferably has a spherical cap shape. By forming the upper end 45 of the main body 31 into a spherical cap shape, it is possible to reduce the air resistance when the fishing float 1 is thrown.

本体４１の拡径部４３の上端と上部４２の下端との境界には円錐台部４７を設け、拡径部４３と上部４２とを滑らかに連結させるのがよい。これにより水中において、内浮き３０が上下動するときの抵抗を小さくすることができる。 It is preferable to provide a truncated cone 47 at the boundary between the upper end of the enlarged diameter portion 43 of the main body 41 and the lower end of the upper portion 42 so that the enlarged diameter portion 43 and the upper portion 42 are smoothly connected. This makes it possible to reduce the resistance when the inner float 30 moves up and down in water.

内浮き３０は、外浮き１０の第１孔２３に本体４１の拡径部４３が位置するように、また外浮き１０の第２孔２４に本体４１の上部４２が位置するように挿通される。内浮き３０は、外浮き１０に対して最も上昇した状態で、上部４２の大部分が外浮き１０から突出し、また拡径部４３の一部及び下部４４が外浮き１０の下端１７から突出する長さを有する。内浮き３０は、外浮き１０に対して最も降下した状態（図４参照）で、上端４５が第２孔２４の上端と面一であるか、僅かに突出するのが好ましい。これにより魚釣り用浮き１を投げたとき空気抵抗を小さくすることができる。 The inner float 30 is inserted so that the enlarged diameter portion 43 of the main body 41 is located in the first hole 23 of the outer float 10 and the upper portion 42 of the main body 41 is located in the second hole 24 of the outer float 10. .. In the inner float 30, most of the upper portion 42 protrudes from the outer float 10, and a part of the enlarged diameter portion 43 and the lower portion 44 protrude from the lower end 17 of the outer float 10 in the state of being most raised with respect to the outer float 10. Has a length. It is preferable that the inner float 30 is in a state of being most lowered with respect to the outer float 10 (see FIG. 4), and the upper end 45 is flush with or slightly protrudes from the upper end of the second hole 24. As a result, the air resistance can be reduced when the fishing float 1 is thrown.

本体４１の代表的な寸法を示せば全長ｈ_０＝６０～７０ｍｍ、拡径部４３の長さｈ_１がｈ_１／ｈ_０＝０．４～０．５、上部４２の長さｈ_２／ｈ_０＝０．３～０．５、拡径部４３の直径がｄ_１＝φ７～９ｍｍ、上部４２の直径ｄ_２がｄ_２／ｄ_１＝０．４～０．５である。但し、本発明に係る魚釣り用浮きにおいて、内浮き３０の本体４１は、この大きさ（数値）に限定されるものではない。 If the typical dimensions of the main body 41 are shown, the total length h ₀ = 60 to 70 mm, the length h ₁ of the enlarged diameter portion 43 is h ₁ / h ₀ = 0.4 to 0.5, and the length h ₂ / of the upper portion 42. h ₀ = 0.3 to 0.5, the diameter of the enlarged diameter portion 43 is d ₁ = φ7 to 9 mm, and the diameter d ₂ of the upper portion 42 is d ₂ / d ₁ = 0.4 to 0.5. However, in the fishing float according to the present invention, the main body 41 of the inner float 30 is not limited to this size (numerical value).

内浮き３０は、本体４１の拡径部４３から下部４４にかけて気密性を有する中空部が設けられ、これが空気室４８となっている。この空気室４８は、内浮き３０の浮力を調整するためのものであり、内浮き３０の浮力は、空気室４８の長さｈ_３及び直径ｄ_３、さらには拡径部４３の長さｈ_１及び直径ｄ_１により制御することができる。空気室４８の気体は、通常空気であるが、浮力調整のために他の気体、ガスを充填してもよい。 The inner float 30 is provided with a hollow portion having airtightness from the enlarged diameter portion 43 of the main body 41 to the lower portion 44, and this is the air chamber 48. The air chamber 48 is for adjusting the buoyancy of the inner float 30, and the buoyancy of the inner float 30 is the length h ₃ and the diameter d ₃ of the air chamber 48, and further the length h of the enlarged diameter portion 43. It can be controlled by ₁ and the diameter _d1 . The gas in the air chamber 48 is usually air, but other gas or gas may be filled for adjusting the buoyancy.

内浮き３０が大きな浮力を確保するには容積の大きい空気室４８を設ける必要がある。本実施形態の内浮き３０では中央部を拡径させ、この拡径部４３に主として空気室４８を設けることで容積の大きい空気室４８を確保する。一方で本体４１全体が大きくなることを防ぐことができる。空気室４８は、中空であるから中実材に比較して強度が低下し易いが、拡径部４３に空気室４８を設ければ肉厚を確保できるため強度低下を防ぐことができる。 In order for the inner float 30 to secure a large buoyancy, it is necessary to provide an air chamber 48 having a large volume. In the inner float 30 of the present embodiment, the diameter of the central portion is enlarged, and the air chamber 48 is mainly provided in the enlarged diameter portion 43 to secure the air chamber 48 having a large volume. On the other hand, it is possible to prevent the entire main body 41 from becoming large. Since the air chamber 48 is hollow, its strength tends to decrease as compared with the solid material, but if the air chamber 48 is provided in the enlarged diameter portion 43, the wall thickness can be secured and the strength decrease can be prevented.

空気室４８の形成要領は特に限定されるものではないが、本体４１の下端４６から拡径部４３に向けて孔を設け、下端４６に栓を嵌め込み接着すればよい。 The procedure for forming the air chamber 48 is not particularly limited, but a hole may be provided from the lower end 46 of the main body 41 toward the enlarged diameter portion 43, and a stopper may be fitted into the lower end 46 for adhesion.

本体４１の材質は、特に限定されるものではないが代表的には合成樹脂、木製である。前記のとおり本体４１には拡径部４３、さらに内部に空気室４８を設けるため、材料の比重、強度等を考慮し材質を選択するのがよい。本体４１には、視認性を高めるために基本的に蛍光塗料が塗布されるためこの点も考慮して材質を決めることが好ましい。また本体４１の表面は、平滑であるのがよい。これにより水中において、外浮き１０に対して内浮き３０が上下動するときの抵抗を小さくすることができる。 The material of the main body 41 is not particularly limited, but is typically synthetic resin or wood. As described above, since the main body 41 is provided with the enlarged diameter portion 43 and the air chamber 48 inside, it is preferable to select the material in consideration of the specific gravity, strength, and the like of the material. Since a fluorescent paint is basically applied to the main body 41 in order to improve visibility, it is preferable to determine the material in consideration of this point as well. Further, the surface of the main body 41 should be smooth. As a result, it is possible to reduce the resistance when the inner float 30 moves up and down with respect to the outer float 10 in water.

ストッパー５０は、外浮き１０に対する内浮き３０の上下方向の移動を規制する部材である。ストッパー５０は、一対の小さな棒状の部材であり、円錐台部４７に平面視において対向する位置に、また正面視において本体４１に直交するように取付けられている。ストッパー５０の両先端部の間隔ｄ_４は、外浮き１０の第１孔２３の直径Ｄ_２よりも僅かに小さく、外浮き１０の第２孔２４の直径Ｄ_３よりも大きく設定されている。これにより内浮き３０は、外浮き１０に対して上方に外れることはない。 The stopper 50 is a member that regulates the vertical movement of the inner float 30 with respect to the outer float 10. The stopper 50 is a pair of small rod-shaped members, and is attached to the truncated cone portion 47 at a position facing the cone 47 in a plan view and orthogonal to the main body 41 in a front view. The distance d ₄ between the two tip portions of the stopper 50 is set to be slightly smaller than the diameter D ₂ of the first hole 23 of the outer float 10 and larger than the diameter D ₃ of the second hole 24 of the outer float 10. As a result, the inner float 30 does not come off upward with respect to the outer float 10.

ストッパー５０は、図３の矢視Ｅ方向に見た側面視において楕円形、紡錘形、流線型が好ましい（図３（Ｃ）参照）。またストッパー５０の表面は、平滑であるのがよい。これにより水中において、外浮き１０に対して内浮き３０が上下動するときの抵抗を小さくすることができる。ストッパー５０は、本体４１と一体的に形成してもよく、本体４１とは別に製作し、本体４１に後付けしてもよい。ストッパー５０の材質は、特に限定されない。 The stopper 50 is preferably elliptical, spindle-shaped, or streamlined in the side view in the direction of arrow E in FIG. 3 (see FIG. 3C). Further, the surface of the stopper 50 should be smooth. As a result, it is possible to reduce the resistance when the inner float 30 moves up and down with respect to the outer float 10 in water. The stopper 50 may be integrally formed with the main body 41, or may be manufactured separately from the main body 41 and retrofitted to the main body 41. The material of the stopper 50 is not particularly limited.

重り６０は、外浮き１０に取付けられ、外浮き１０の重量バランス及び姿勢を整える部材である。本実施形態では、リング状の重り６０が、第１孔２３の下部に固定されている。重り６０を外浮き１０の下部又は底部に取付けることで重心が低くなり姿勢が安定する。重り６０の内径Ｄ_４は、内浮きの本体４１の拡径部４３の直径ｄ_１よりも大きく、ストッパー５０の両端の間隔ｄ_４よりも小さく設定されている。これによりストッパー５０は、外浮き１０の段差部２２及び重り６０を通過することができず、内浮き３０の上下動の範囲が規制される。 The weight 60 is a member attached to the outer float 10 to adjust the weight balance and posture of the outer float 10. In the present embodiment, the ring-shaped weight 60 is fixed to the lower part of the first hole 23. By attaching the weight 60 to the lower part or the bottom of the outer float 10, the center of gravity is lowered and the posture is stabilized. The inner diameter D ₄ of the weight 60 is set to be larger than the diameter d ₁ of the enlarged diameter portion 43 of the inner floating main body 41 and smaller than the distance d ₄ at both ends of the stopper 50. As a result, the stopper 50 cannot pass through the step portion 22 of the outer float 10 and the weight 60, and the range of vertical movement of the inner float 30 is restricted.

以上のように魚釣り用浮き１では、外浮き１０の貫通孔２０の段差部２２、貫通孔２０の下端に取付けられた重り６０、内浮き３０の円錐台部４７に取付けられたストッパー５０とで内浮き３０の抜止め手段が構成される。 As described above, in the fishing float 1, the step portion 22 of the through hole 20 of the outer float 10, the weight 60 attached to the lower end of the through hole 20, and the stopper 50 attached to the truncated cone portion 47 of the inner float 30 are used. A means for retaining the inner float 30 is configured.

上記のとおり重り６０は、ストッパーとしての役目も備え、重り６０の上端は、外浮き１０に対する内浮き３０の最も低い降下位置を決める。このため重り６０の高さは、この点を考慮して設定される。重り６０の材質は、寸法、比重から所定の重量となるよう適宜選択し決定される。重り６０の形状、構造は、本実施形態に限定されるものではないが、重り６０をリング状とし、これを第１孔２３に嵌め込む構造は、製造し易く好ましい。 As described above, the weight 60 also serves as a stopper, and the upper end of the weight 60 determines the lowest descent position of the inner float 30 with respect to the outer float 10. Therefore, the height of the weight 60 is set in consideration of this point. The material of the weight 60 is appropriately selected and determined from the dimensions and the specific weight so as to have a predetermined weight. The shape and structure of the weight 60 are not limited to the present embodiment, but a structure in which the weight 60 has a ring shape and is fitted into the first hole 23 is preferable because it is easy to manufacture.

魚釣り用浮き１において、内浮き３０の上部４２と第２孔２４との隙間α及び内浮き３０の拡径部４３と重り６０との隙間βは、内浮き３０が上下動するときの水の出入口となる。このためこの隙間α，βが極端に狭い、あるいは隙間がないときは、この部分が抵抗となり内浮き３０の上下動の動きが悪くなる。一方、その部分の間隔が極端に広いと内浮き３０の姿勢が不安定となる。本実施形態の魚釣り用浮き１は、これらの点を考慮し、内浮き３０の上部４２と第２孔２４との隙間α及び内浮き３０の拡径部４３と重り６０との隙間βが設定されている。 In the fishing float 1, the gap α between the upper portion 42 of the inner float 30 and the second hole 24 and the gap β between the enlarged diameter portion 43 of the inner float 30 and the weight 60 are water when the inner float 30 moves up and down. It will be a doorway. Therefore, when the gaps α and β are extremely narrow or there is no gap, this portion becomes a resistance and the vertical movement of the inner float 30 becomes poor. On the other hand, if the distance between the portions is extremely wide, the posture of the inner float 30 becomes unstable. In the fishing float 1 of the present embodiment, in consideration of these points, a gap α between the upper portion 42 of the inner float 30 and the second hole 24 and a gap β between the enlarged diameter portion 43 of the inner float 30 and the weight 60 are set. Has been done.

環７０は、中浮き３０の下端に回転自在に取付けられた部材であり、スイベルなどが該当する。環７０には、釣り糸１００が固定され、または釣り糸１００が挿通され使用される。よって魚釣り用浮き１は、固定浮き又は遊動浮きとして使用することができる。 The ring 70 is a member rotatably attached to the lower end of the float 30, and corresponds to a swivel or the like. A fishing line 100 is fixed to the ring 70, or a fishing line 100 is inserted and used. Therefore, the fishing float 1 can be used as a fixed float or a floating float.

以上からなる本実施形態の魚釣り用浮き１は、流線型、涙滴型、紡錘型、卵型、円錐型又は角錐型を有する外浮き１０が棒状の内浮き３０を上下動可能に支持する構造からなり、基本的に棒浮き及び円錐浮きの機能を備える。特に内浮き３０は、中央に縦長の拡径部４３を設け、ここに空気室４８を設けるので内浮き３０の強度を低下させることなく大きな空気室４８を確保することができる。このような内浮き３０は、拡径部４３及び／又は空気室４８の径及び長さを調整することで所望の浮力を得ることができる。
The fishing float 1 of the present embodiment comprising the above has a structure in which an outer float 10 having a streamline type, a teardrop type, a spindle type, an egg type, a conical type or a pyramid type supports a rod-shaped inner float 30 so as to be movable up and down. It consists of and basically has the functions of rod float and cone float. In particular, since the inner float 30 is provided with a vertically long diameter-expanded portion 43 in the center and an air chamber 48 is provided therein, a large air chamber 48 can be secured without reducing the strength of the inner float 30. Such an inner float 30 can obtain a desired buoyancy by adjusting the diameter and length of the enlarged diameter portion 43 and / or the air chamber 48.

また魚釣り用浮き１は、内浮き３０の外浮き１０に対する抜止め手段が外浮き１０の内部に設けられているので外観形状がシンプルですっきりとしている。また外浮き１０の他に、内浮き３０の下部４４も下端４６に向かって先細りの流線型、円錐型又は角錐型であるので入水抵抗・水中抵抗が小さい。さらに外浮き１０に対して内浮き３０が最も降下したとき、内浮き３０の上端４５が貫通孔２０の上端から僅かに突出している状態であるから、本魚釣り用浮き１を投げたときの空気抵抗が少ない。このため魚釣り用浮き１は、遠投性能、狙ったところに投げることができるコントロール性能に優れる。 Further, the fishing float 1 has a simple and neat appearance because a means for retaining the outer float 10 of the inner float 30 is provided inside the outer float 10. Further, in addition to the outer float 10, the lower portion 44 of the inner float 30 is also streamlined, conical or pyramidal, which tapers toward the lower end 46, so that the water entry resistance and the water resistance are small. Further, when the inner float 30 descends most with respect to the outer float 10, the upper end 45 of the inner float 30 is in a state of slightly protruding from the upper end of the through hole 20, so that the air when the main fishing float 1 is thrown. There is little resistance. Therefore, the fishing float 1 is excellent in long-distance casting performance and control performance that allows it to be thrown at a target location.

また魚釣り用浮き１は、内浮き３０の上部４２と拡径部４３との境界が円錐台部４７となっており、ストッパー５０の横断面も水中における上下方向の移動に対する抵抗が小さい形状となっている。また貫通孔２０内への水の出入りのための流路も十分に確保されている。これらは内浮き３０が上下動するときの抵抗を低減させる抵抗低減手段である。このため内浮き３０の水中での上下動に対する抵抗が小さく、アタリに的確に反応することができる。 Further, in the fishing float 1, the boundary between the upper portion 42 of the inner float 30 and the enlarged diameter portion 43 is a truncated cone portion 47, and the cross section of the stopper 50 also has a shape having a small resistance to vertical movement in water. ing. Further, a sufficient flow path for water to enter and exit the through hole 20 is sufficiently secured. These are resistance reducing means for reducing the resistance when the inner float 30 moves up and down. Therefore, the resistance of the inner float 30 to the vertical movement in water is small, and it is possible to react accurately to Atari.

以上のように本実施形態の魚釣り用浮き１は、公知の棒浮き及び円錐浮きに対応する内浮き３０及び外浮き１０それぞれの機能・性能を最大限発揮できるように形状・構造・浮力のバランスなどが決められているため、アタリに対する応答性、遠投性能、投げたときのコントロール性などに優れ、使い勝手のよい魚釣り用浮きとなる。 As described above, the fishing float 1 of the present embodiment has a balance of shape, structure and buoyancy so as to maximize the functions and performances of the inner float 30 and the outer float 10 corresponding to the known rod float and conical float. Because it has been decided, it has excellent responsiveness to atari, long-distance casting performance, controllability when throwing, etc., making it an easy-to-use fishing float.

次に本発明の第１実施形態の魚釣り用浮き１の変形例を示す。図５は、本発明の第１実施形態の魚釣り用浮き１の変形例である魚釣り用浮き２、３、４の断面図であり、図６は、本発明の第１実施形態の魚釣り用浮き１の内浮き３０の変形例である内浮き３４、３５、３６、３７、３８、３９の正面図である。図１から図４に示す第１実施形態の魚釣り用浮き１、外浮き１０及び内浮き３０と同一の構成には同一の符号を付して説明を省略し、以下、第１実施形態の魚釣り用浮き１、外浮き１０及び内浮き３０との相違点を中心に説明する。 Next, a modified example of the fishing float 1 of the first embodiment of the present invention will be shown.

Hereinafter, the fishing of the first embodiment will be omitted. The differences between the float 1, the outer float 10, and the inner float 30 will be mainly described.

図５（Ａ）の魚釣り用浮き２は、魚釣り用浮き１と基本構成を同じくするが、以下の点で、魚釣り用浮き１と異なる。魚釣り用浮き２の内浮き３１は、上端４５に内浮き３１の降下を規制するストッパー５１を備える。内浮き３１の上昇を規制するストッパーは、上部４２と拡径部４３との間に設けられた段差部５２である。また外浮き１１は、最大直径部１５から下端１７までが円錐台形状を有し、正面視において最大直径部１５から下端１７に向け直線的に縮径している。 The fishing float 2 in FIG. 5A has the same basic configuration as the fishing float 1 but differs from the fishing float 1 in the following points. The inner float 31 of the fishing float 2 includes a stopper 51 at the upper end 45 that regulates the descent of the inner float 31. The stopper that regulates the rise of the inner float 31 is a step portion 52 provided between the upper portion 42 and the enlarged diameter portion 43. Further, the outer float 11 has a truncated cone shape from the maximum diameter portion 15 to the lower end 17, and is linearly reduced in diameter from the maximum diameter portion 15 to the lower end 17 in front view.

図５（Ｂ）の魚釣り用浮き３は、魚釣り用浮き１と基本構成を同じくするが、以下の点で、魚釣り用浮き１と異なる。魚釣り用浮き３の外浮き１２は、最大直径部１５から上部が円錐台形状を有し、正面視において上端１６に向けて直線的に傾斜している。また内浮き３２は、拡径部４３のうち下半分が僅かに縮径している。 The fishing float 3 of FIG. 5B has the same basic configuration as the fishing float 1 but differs from the fishing float 1 in the following points. The outer float 12 of the fishing float 3 has a truncated cone shape at the upper part from the maximum diameter portion 15, and is linearly inclined toward the upper end 16 in the front view. Further, in the inner float 32, the lower half of the enlarged diameter portion 43 is slightly reduced in diameter.

図５（Ｃ）の魚釣り用浮き４は、魚釣り用浮き１と基本構成を同じくするが、以下の点で、魚釣り用浮き１と異なる。魚釣り用浮き４の外浮き１３は、最大直径部１５から下端１７までが円錐台形状を有し、正面視において最大直径部１５から下端１７に向け直線的に縮径している。また外浮き１０に比較して外浮き１３の高さ（全高）Ｈ_０が低い。但し、外浮き１３の高さ（全高）Ｈ_０は、外浮き１０の高さ（全高）Ｈ_０と同じであってもよい。また重り６１が、外浮き１３の下部外壁面の一部を形成している。重り６１がストッパーとして機能する点は、第１実施形態の重り６０と同じである。 The fishing float 4 of FIG. 5C has the same basic configuration as the fishing float 1 but differs from the fishing float 1 in the following points. The outer float 13 of the fishing float 4 has a truncated cone shape from the maximum diameter portion 15 to the lower end 17, and is linearly reduced in diameter from the maximum diameter portion 15 to the lower end 17 in front view. Further, the height (total height) H ₀ of the outer float 13 is lower than that of the outer float 10. However, the height (total height) H ₀ of the outer float 13 may be the same as the height (total height) H ₀ of the outer float 10. Further, the weight 61 forms a part of the lower outer wall surface of the outer float 13. The point that the weight 61 functions as a stopper is the same as that of the weight 60 of the first embodiment.

魚釣り用浮き４の内浮き３３は、上部４２と拡径部４３の境界に略円錐台状のストッパー５４が設けられている。これに合わせて外浮き１３の段差部２２も円錐状となっている。 The inner float 33 of the fishing float 4 is provided with a substantially truncated cone-shaped stopper 54 at the boundary between the upper portion 42 and the enlarged diameter portion 43. Along with this, the stepped portion 22 of the outer float 13 is also conical.

図６（Ａ）の内浮き３４は、棒状のストッパー５０が１つである。図６（Ｂ）の内浮き３５は、上部４２が上端４５に向けて拡径しており、図６（Ｃ）の内浮き３６は、上部４２が上端４５に向けて縮径している。図６（Ｄ）の内浮き３７は、下部４４が縮径しておらず中央の拡径部４３と同じ直径である。また図６（Ｄ）の内浮き３７は、一対の棒状のストッパー５０に代えて、円板状のストッパー５５が設けられている。 The inner float 34 in FIG. 6A has one rod-shaped stopper 50. In the inner float 35 of FIG. 6 (B), the upper portion 42 has an enlarged diameter toward the upper end 45, and in the inner float 36 of FIG. 6 (C), the upper portion 42 has a diameter reduced toward the upper end 45. The inner float 37 in FIG. 6D has the same diameter as the enlarged diameter portion 43 in the center without reducing the diameter of the lower portion 44. Further, the inner float 37 in FIG. 6D is provided with a disk-shaped stopper 55 instead of the pair of rod-shaped stoppers 50.

図６（Ｅ）の内浮き３８は、空気室４８が、内浮き３８の上部４２及び拡径部４３に設けられており、下部４４には空気室が設けられていない。図６（Ｆ）の内浮き３９は、空気室４８が、内浮き３９の上部４２、拡径部４３及び下部４４に設けられている。内浮き３４、３５、３６、３８、３９は、下部４４が下端４５に向かって直線的に縮径しているが、内浮き３０と同様に正面視において下部が外側に向けて僅かに湾曲していてもよい。 In the inner float 38 of FIG. 6 (E), the air chamber 48 is provided in the upper portion 42 and the diameter-expanded portion 43 of the inner float 38, and the lower portion 44 is not provided with an air chamber. In the inner float 39 of FIG. 6 (F), the air chamber 48 is provided in the upper portion 42, the diameter-expanded portion 43, and the lower portion 44 of the inner float 39. In the inner floats 34, 35, 36, 38, 39, the lower portion 44 is linearly reduced in diameter toward the lower end 45, but the lower portion is slightly curved outward in the front view like the inner float 30. You may be.

図５及び図６を用いて本発明の第１実施形態の魚釣り用浮き１の変形例を示したが、外浮き１１、１２、１３は、外浮き１０と同様に外観形状が流線型、涙滴型、紡錘型、卵型、円錐型又は角錐型であり、投げたときの空気抵抗、さらには水中で上下動するときの抵抗が小さい。また内浮き３１、３２、３３、３４、３５、３６、３７、３８、３９は、内浮き３０と同様に細長い棒状の浮きであり、さらに抵抗低減手段を備えるのでアタリに対して敏感に反応することができる。また内浮き３１、３２、３３、３４、３５、３６、３７、３８、３９は、内浮き３０と同様に、少なくとも拡径部４３に空気室４８を備えるので強度を確保しつつ容積の大きい空気室４８を設けることができる。 5 and 6 show a modification of the fishing float 1 of the first embodiment of the present invention, but the outer floats 11, 12, and 13 have a streamlined appearance and teardrops similar to the outer float 10. It is a mold, spindle, oval, conical or pyramidal, and has low air resistance when thrown and resistance when moving up and down in water. Further, the inner floats 31, 32, 33, 34, 35, 36, 37, 38, 39 are elongated rod-shaped floats similar to the inner float 30, and further have resistance reducing means, so that they react sensitively to Atari. be able to. Further, the inner floats 31, 32, 33, 34, 35, 36, 37, 38, 39 are provided with an air chamber 48 at least in the enlarged diameter portion 43 in the same way as the inner float 30, so that the air has a large volume while ensuring the strength. A room 48 can be provided.

図７は、本発明の第２実施形態の魚釣り用浮き５の構造を説明するための図である。図１から図４に示す本発明の第１実施形態の魚釣り用浮き１と同一の構成には同一の符号を付して説明を省略する。以下、第１実施形態の魚釣り用浮き１との相違点を中心に説明する。 FIG. 7 is a diagram for explaining the structure of the fishing float 5 according to the second embodiment of the present invention. The same components as those of the fishing float 1 of the first embodiment of the present invention shown in FIGS. 1 to 4 are designated by the same reference numerals and the description thereof will be omitted. Hereinafter, the differences from the fishing float 1 of the first embodiment will be mainly described.

本発明の第２実施形態の魚釣り用浮き５の構成は、本発明の第１実施形態の魚釣り用浮き１と基本的に同じであり、作用効果も基本的に本発明の第１実施形態の魚釣り用浮き１と同じである。相違点は、内浮き４０の構造にある。より具体的には、第２実施形態の魚釣り用浮き５の内浮き４０は、本体４１の上部４２が拡径部４３以下の部材に対して着脱可能に構成されている。 The configuration of the fishing float 5 of the second embodiment of the present invention is basically the same as that of the fishing float 1 of the first embodiment of the present invention, and the action and effect are basically the same as those of the first embodiment of the present invention. It is the same as the fishing float 1. The difference lies in the structure of the inner float 40. More specifically, the inner float 40 of the fishing float 5 of the second embodiment is configured so that the upper portion 42 of the main body 41 can be attached to and detached from the member having the enlarged diameter portion 43 or less.

内浮き４０の本体４１の上部４２は、上端４５が閉じた筒状のキャップ８０からなる。内浮き４０の本体４１の拡径部４３の上端には、キャップ８０が嵌り込む棒状の突起４９が設けられている。突起４９の長さは特に限定されるものではないが、外浮き１０に対してキャップ８０を取外した本体４１を最も上昇させたとき、上端が外浮き１０の上端１６と面一となる程度のものが好ましい。 The upper portion 42 of the main body 41 of the inner float 40 is composed of a cylindrical cap 80 with the upper end 45 closed. A rod-shaped protrusion 49 into which the cap 80 is fitted is provided at the upper end of the enlarged diameter portion 43 of the main body 41 of the inner float 40. The length of the protrusion 49 is not particularly limited, but when the main body 41 from which the cap 80 is removed is raised most with respect to the outer float 10, the upper end is flush with the upper end 16 of the outer float 10. Those are preferable.

キャップ８０の内径と突起４９の外径とは略同一であり、突起４９に対してキャップ８０を押し込むことでぐらつくことなく連結される。棒状の突起４９を、上端に向かって僅かに縮径させた先細り形状とし、キャップ８０の下部を弾性変形可能に構成すれば、キャップ８０をより堅固に、また液密可能に連結させることもできる。 The inner diameter of the cap 80 and the outer diameter of the protrusion 49 are substantially the same, and by pushing the cap 80 into the protrusion 49, the cap 80 is connected without wobbling. If the rod-shaped protrusion 49 has a tapered shape slightly reduced in diameter toward the upper end and the lower portion of the cap 80 is elastically deformable, the cap 80 can be connected more firmly and liquid-tightly. ..

キャップ８０の外径は、基本的に第１実施形態の内浮き３０の上部４２の直径ｄ_２と同じであり、キャップ８０の長さｈ_４は、基本的には突起４９に嵌め込んだとき、第１実施形態の内浮き３０と同じ寸法になるようにすればよい。キャップ８０の内部空間８１の高さｈ_５も特に限定されるものではない。本実施形態では、内部空間８１の高さｈ_５がキャップ８０の長さｈ_４と略同一であるが、内部空間８１の高さｈ_５を突起４９の高さと略同一としてもよい。突起４９の高さに比較して内部空間８１の高さｈ_５を大きくすれば、突起４９にキャップ８０を取付けたとき内部に空気室ができる。 The outer diameter of the cap 80 is basically the same as the diameter d ₂ of the upper portion 42 of the inner float 30 of the first embodiment, and the length h ₄ of the cap 80 is basically when fitted into the protrusion 49. , The size may be the same as that of the inner float 30 of the first embodiment. The height h ₅ of the internal space 81 of the cap 80 is also not particularly limited. In the present embodiment, the height h ₅ of the internal space 81 is substantially the same as the length h ₄ of the cap 80, but the height h ₅ of the internal space 81 may be substantially the same as the height of the protrusion 49. If the height h ₅ of the internal space 81 is made larger than the height of the protrusion 49, an air chamber is created inside when the cap 80 is attached to the protrusion 49.

キャップ８０の材質は、軽いものが好ましく、基本的には第１実施形態の内浮き３０の本体４１と同様に考えればよい。またキャップ８０にゴム弾性を有する素材を使用してもよい。キャップ８０の材質は、本体４１の拡径部４３以下の部材と同じ材質であっても異なっていてもよい。キャップ８０は、表面が平滑であるのがよく、表面に蛍光塗料を塗布する点も第１実施形態の内浮き３０と同様に考えればよい。 The material of the cap 80 is preferably light, and basically the same as the main body 41 of the inner float 30 of the first embodiment may be considered. Further, a material having rubber elasticity may be used for the cap 80. The material of the cap 80 may be the same as or different from the member of the main body 41 having the enlarged diameter portion 43 or less. The surface of the cap 80 is preferably smooth, and the point that the fluorescent paint is applied to the surface may be considered in the same manner as the inner float 30 of the first embodiment.

第２実施形態の魚釣り用浮き５は、内浮き４０の本体４１の上部４２が拡径部４３以下の部材に対して着脱可能に構成されているので、キャップ８０を取外せばコンパクトになり持ち運びが容易となる。予め長さｈ_４の異なるキャップ８０を準備しておけば、釣り場の状況に応じ適したものを使用することができ使い勝手がよくなる。またキャップ８０を別体とすることで製造も容易となる。またキャップ８０に市販の樹脂製キャップ、ゴム製キャップ等を用いれば魚釣り用浮き５を安価に製造することができる。 The fishing float 5 of the second embodiment is configured so that the upper portion 42 of the main body 41 of the inner float 40 can be attached to and detached from the member having the diameter expansion portion 43 or less, so that the cap 80 can be removed to make it compact and portable. Becomes easier. If caps 80 having different lengths _h4 are prepared in advance, it is possible to use a cap 80 suitable for the situation of the fishing spot, and the usability is improved. Further, by separating the cap 80, it becomes easy to manufacture. Further, if a commercially available resin cap, rubber cap, or the like is used for the cap 80, the fishing float 5 can be manufactured at low cost.
