Description

【０００１】
【発明の属する技術】
本発明は海，川，湖等における魚釣りの際に用いられる水中沈下型釣用浮子に関する。
【０００２】
【従来の技術】
近年、魚釣りに使用される釣用浮子においては、釣果を向上させるために各種釣用浮子が開発され市販されている。
以下に従来の釣用浮子について、図面を参照しながら説明する。
図６は従来の釣用浮子の一例を示す断面図である。
１′は従来のあたり浮子として用いられる釣用浮子、２′は桐等の木製又は合成樹脂等で形成された略団栗状の浮子本体、２ａ′は浮子本体２′の下部に形成された平面下壁部、２ｂ′は浮子本体２′の平面下壁部２ａ′の略中央部から浮子本体２′の他方の頂部に亘って略直線状に穿孔された糸挿通用孔、４′は浮子本体２′の平面下壁部２ａ′に貼着等で固定された鉛等の金属製等で形成された略半球状の重錘部、４ａ′は重錘部４′の略中央部に浮子本体２′の糸挿通用孔２ｂ′に連通して形成された糸挿着用貫通孔である。
以上のように構成された従来の釣用浮子を用いて、釣り上げる魚の種類や釣り場の状況等に応じて、重錘部４′の重量の違う釣用浮子１′を適宜選択し、水面浮上型の釣用浮子１′や水中沈下型の浮き等各種の釣用浮子１′として使い分けられていた。
しかし、釣り人にとってこれら浮力の異なる各種の釣用浮子を常時携行することは非常に面倒であった。また、浮子を潮流等の釣場の状況や魚種に合わせて逐次取り替えたるため、その都度道糸を切ったりして調整し直さなければならず、作業が非常に煩わしいという問題点を有していた。又、釣り場や釣り時の水流，潮流，風，波，天候等の自然条件や釣り対象の魚種によって、即座に仕掛け等を調整することは、熟練を要し時間を要するという問題点を有していた。
この問題点を解決するために、浮子と重錘部とが一体に形成された釣用浮子において、重錘部を交換することにより、釣用浮子の浮力を変えて、釣り場や釣り時の水流，潮流，風，波，天候等の自然条件や釣り対象の魚種に応じて魚の警戒心をなくす釣り方法が、研究開発され、この釣り方法に好適な釣用浮子が種々開発されている。
例えば、▲１▼実開昭６３−９８０７６号公報（以下、イ号公報という）には、浮力木片の一端に浮力調整用バラストを封入できる空洞を有する浮力調整おもりの固定手段を備えた簡易つり浮き用浮力調整おもりが開示されている。
▲２▼実開昭６４−４１２７４号公報（以下、ロ号公報という）には、釣用浮子が道糸への取付用基体と上半部の浮子本体とに分割され、該基体には上方に開口する浮力調整用錘収納用の凹部が軸線方向に沿って形成され、連結部が圧入嵌合構造に形成された釣用浮力調整浮子が開示されている。
▲３▼登録実用新案第３００２０９２号公報（以下、ハ号公報という）には、盲穴を形成した浮子本体と、該盲穴に着脱自在に装着される相互に異なった重量を有する複数の挿入部材とを備え、浮力を適宜調整変更することが可能な釣用浮子が開示されている。
▲４▼実開昭５６−２１９７４号公報（以下、ニ号公報という）には、浮子本体に形成された中空部と該中空部に水密状で上下動自在に配設された軸状部とを備え、該軸状部を上下動させることにより空気室の容量を調整して浮力を調節する釣用浮子が開示されている。
▲５▼実開平６−８１２７３号公報（以下、ホ号公報という）には、中央部に形成された中空状の挿通孔を備えた親浮子と、該挿通孔に上下動自在に挿着される各種棒体からなるあたり浮子とを備え、釣場の条件に合わせて該当たり浮子を取替自在とした釣用浮子が開示されている。
▲６▼実開昭６３−１７４６７６号公報（以下、ヘ号公報という）には、キャップケースの中におもり表示ラインの入ったおもり移動棒と該移動棒に摺動自在に配設された輪型のおもりとが内蔵され、うきトップには発光ダイオードとリチウム電池が内蔵された釣用オモリ内蔵浮力調節ウキが開示されている。

【発明が解決しようとする課題】
しかしながら、上記従来の釣用浮子の構成では、以下の問題点を有していた。すなわち、
▲１▼イ号公報に記載のものは、浮力調整用にバラストを挿入する旨記載されているが、バラストは重さが一定しないため、空洞内で偏ってしまい浮子の中心軸がずれ、波等によりバラストがずれて浮力が一定しないという問題点を有していた。また、浮力調整用バラストを固定するため、浮力木片に止め穴を加工した後、該おもりを浮力木片と接着固定し、更に接合部の破損を防止するため該おもりを埋め込んだ浮力木片の外周を糸で巻いて固定補強する構造なので、生産時の作業が雑で作業性や生産性に欠けるという問題点を有していた。更に重量が一定なので釣場の状況に応じて取り替えねばならず、幾種類もの該おもりを常備しなければならないという問題点を有していた。
▲２▼ロ号公報に記載のものは、浮力調整用錘収納用凹部の形成や水密状の空気室の形成を要し、圧入嵌合体がバネにより構成されているので、構造が複雑で部品点数も多く製造が煩雑で生産性に欠けるとともに、バネ体が金属製なので海水等により腐食し耐久性に欠けるという問題点を有していた。また、浮力調整用錘が該凹部の径と略同径かつ浮力調整のため複数に分割して作成された特定の構造を有するので、釣場等で紛失したりしたときは浮子が使用不能になるという問題点を有していた。
▲３▼ハ号公報に記載のものは、複数の柱状材と、複数の密封用ボルトを釣場の条件に合わせてこれらを組み合わせて、浮力を調整する構造になっているが、船上や狭い岩場で部品を組み合わせるのは非常に困難な上、構造が複雑で部品点数も多く製造が困難という問題点を有していた。また、柱状部材や密封用ボルトが特定の構造なので釣中に誤って海中等を落とした場合、最早使用不能となり耐久性に欠けるという問題点を有していた。
▲４▼ニ号公報に記載のものは、圧縮用部品を浮子中央の中空部に圧入することにより、浮力を調整する構造になっているが、重さの調整が困難で浮力が一定しないという問題点を有していた。
▲５▼ホ号公報に記載のものは、浮力を調整するためには幾種類ものストレート棒体を準備しなければならず、また、ストレート棒体を浮力に合わせて調整するのは極めて困難で浮力の調整（位置決め）が難しいという問題点を有していた。
▲６▼ヘ号公報に記載のものは、構造が複雑で部品点数も多く製造が困難な上、釣場で一々キャップケースを外したりして分解せねばならず使用しづらいという問題点を有していた。
上述したように、従来の浮子はいずれも、製造が困難な上、耐久性に欠け、取扱いが困難で、浮力の調整に時間を要すという問題点を有していた。
更に、従来のように特製の重錘しか使用できない浮子の場合、部品点数が増加し、特別に製造する必要があり原価も高く汎用性に欠けるという問題点を有していた。
【０００４】
本発明は上記従来の問題点を解決するもので、重錘部としてガン玉等の鉛玉を使用するので、潮流や天候，波浪，時合い等の釣場の状況に即座に対応でき、簡単にかつ早急に浮力を調整することができ、構造が簡単で量産性に適し、また、重錘部としてガン玉等の鉛玉を用いることができるので釣場に１個の水中沈下型釣用浮子のみ持参するだけで良く、利便性に優れた水中沈下型釣用浮子を提供することを目的とする。
【０００５】

【０００６】
ここで、浮子本体の形状としては、略球状，略団栗状，略棒状，略円錐状，略楕円状，略卵状，紡錘状等，さらに上面を平面状に形成したものや略逆円錐状等の変形浮子等が挙げられる。又、浮子本体は、木製や合成樹脂製の中実状又はステンレス製等の中空状もしくは合成樹脂又は金属製の外殻部と内部に充填されたポリウレタン等の発泡樹脂体とからなる二層構造等いずれであってもよい。
又、水中沈下型釣用浮子の材質としては、桐，檜，コルク，ラミン，カシ，パーシモン等の木製，ＡＢＳ樹脂（アクリロニトリルブタジエンスチレン樹脂）．ＡＳ樹脂（アクリロニトリルスチレン共重合樹脂），ＨＩＰＳ（ハイインパクトポリスチレン），ポリカーボネート，ポリ塩化ビニル，ポリプロピレン，ポリエチレン，ポリスチレン，又はポリウレタン等の発泡樹脂等の合成樹脂等が挙げられる。又、水中沈下型釣用浮子は前述した材質を組み合わせたものであってもよい。例えば、水中沈下型釣用浮子を２分割した略半球状，略砲弾状，略円錐状等を各々異なる材質で形成し、これを接着剤等で一体化したものであってもよい。更に、水中沈下型釣用浮子は、視認性を向上させるために塗装等が施される。
貫通孔部は、浮子本体の軸方向の一端部から他端部に亘って形成される。材質が木製や発泡樹脂製等で水の浸入し易いものは、貫通孔部内にポリ塩化ビニル，ポリプロピレン，ポリエチレン，ナイロン等の合成樹脂製の筒体を挿着し、接着剤等で固定してもよい。もしくは、貫通孔部の内面をエポキシ樹脂系やポリウレタン樹脂等の合成樹脂でコートしてもよい。
貫通孔部の径としては、２．５mm〜８mm程度の円筒状、又は多角筒状に形成される。好ましくは、市販のガン玉やカミツブシ等の鉛玉が一列に並んで入る程度の径が好ましい。
釣糸通し部は、一端部が貫通孔部の端部に嵌合され水密状に接着剤等で固定される。また、他端部には、環状に形成された釣糸通し用の環状物が回動自在に配設されると、釣糸通し用の環状物の向きが自在となり、道糸がスムーズに釣糸通し部を通過することができ、初期の魚の食いつきによる水中沈下型釣用浮子の抵抗を無くすので、釣果を向上させることができる。
重錘部としては、ガン玉等の鉛玉の他、銅，真鍮，ベアリング等のステンレス鋼の玉状のものが用いられるが、ガン玉等の鉛玉がどこでも入手できるので特に好ましい。重錘部の形状としては、特に限定されるものではなく、略球状，略半球状，略楕円状，又は半楕円状，略卵状，又は半卵状，略円錐状，略角錐状等種々のものが用いられる。
重錘部として、市販の鉛玉（通称、ガン玉やカミツブシ）やステンレス製のボールベアリングを使用できるようにすると、釣場の条件に合わせて即座に必要量を適宜調整できるので便利であり、重錘部の径としては、２mm〜７．５mmが用いられる。
封緘部としては、桐，檜，コルク，ラミン，カシ，パーシモン等の木製，ＡＢＳ樹脂，ＡＳ樹脂，ＨＩＰＳ，ポリカーボネート，ポリ塩化ビニル，ポリプロピレン，ポリエチレン，ポリスチレン，又はポリウレタン等の発泡樹脂等の合成樹脂、天然ゴム，ＮＢＲ，アクリルゴム等の合成ゴム等が挙げられる。軽量で、封緘が容易なものが望ましい。側壁部の周囲に亘って突条部を１乃至複数条設けると、簡単な構成で、海水が貫通孔部内に浸入するのを防止できる。更に、頂部もしくはその近辺に把持用の突条部や笠部を設けると、ワンタッチ式に容易に脱着でき重錘部の出し入れを簡単に行うことができるとともに、貫通孔部に封緘部が詰まり抜けなくなるのを防止することができる。
また、封緘部の頂部や笠部の頂部に嵌着孔部を設け、ケミホタル（日本化学発光株式会社製）等の発光体を嵌着自在にしてもよいし、又は発光体を直接貫通孔部に差し込み封緘してもよい。
更に、封緘部が膨出状に形成され発光ダイオードとリチウム電池等の電源が封入された構造のものでもよい。
【０００７】
【作用】
この構成によって、前記浮子本体の軸方向の一端部から他端部へ亘って形成された貫通孔部に収納された１乃至複数の重錘部を設けたので、釣場の状況や魚種に合わせて、狭い船上や岩場等でも重錘部の数の調整のみによる簡単な作業で即座に浮力を調整することができる。
浮子本体を木製，発泡樹脂製等で形成した場合に、貫通孔部を合成樹脂製の筒体を挿着固定したり、合成樹脂のコート層を形成することにより、内部への海水の浸入を防止でき、浮子本体の腐食や浮力の変化を防止することができる。
重錘部としてガン玉やカミツブシ等の鉛玉を用いることにより、簡単に挿入することができる上、波の影響を受けることなく潮流や天候，波浪，時合いに即座に対応して、浮力の調整を容易に行うことができ、また、ガン玉等の鉛玉は何処でもまた何時でも簡単に入手できるので汎用性や耐久性に優れる。
封緘部をゴム体，合成樹脂製等の弾力性のある材質で形成し、貫通孔部と接触する側壁部の周囲に亘って突条部を設けると、簡単な構成で、海水が貫通孔部内に浸入するのを防止できる。更に、頂部に把持用の突条部や笠部を設けると、ワンタッチ式に容易に開けたり閉めたりすることができるとともに、貫通孔部に封緘部が詰って抜けなくなるのを防止することができる。
更に、天候や刻々と変化する潮の流れの変化等により、逐次水中沈下型釣用浮子を道糸から取り外して交換する必要がなく、赤，橙，緑，黄色等からなる耐水性の塗料や表面に螢光塗料を塗布した封緘部や、封緘部に嵌着された発光体や、封緘部を空洞とし発光体や発光ダイオード等を内蔵した封緘部のみを付け替えれば、視認性を状況に応じて確保できるので、作業性，操作性及び利便性を向上できる。
釣糸通し部が回動自在に形成されたので、釣糸が釣糸通し部に対してスムーズに通過でき、重錘部の数の調整による水中沈下型釣用浮子の浮力調整を極めて有効に利用することができ、初期の魚の食いつきに極めて良好に対応でき、釣果を効率良く得ることができる。

[Technology to which the Invention belongs]
The present invention relates to an underwater sinking type float for fishing in the sea, river, lake or the like.
[0002]

However, it is very troublesome for an angler to always carry these various types of fishing floats having different buoyancy. In addition, since the floats are sequentially replaced in accordance with the fishing conditions such as the tide and the type of fish, it is necessary to cut and adjust the thread each time, and the work is extremely troublesome. I was In addition, immediately adjusting a mechanism or the like according to natural conditions such as a fishing place or a current, a tide, a wind, a wave, weather, or the like at the time of fishing requires a skill and a time. Was.
In order to solve this problem, in a fishing float in which a float and a weight portion are integrally formed, by changing the weight portion, the buoyancy of the fishing float is changed to change the buoyancy of the fishing float and the water flow at the time of fishing. Fishing methods have been researched and developed to eliminate the caution of fish according to natural conditions such as sea currents, tides, winds, waves, weather, and the type of fish to be fished. Various fishing floats suitable for this fishing method have been developed.
For example, (1) Japanese Utility Model Laid-Open Publication No. 63-98076 (hereinafter referred to as "A") discloses a simple suspension provided with a buoyancy adjusting weight fixing means having a cavity in which a buoyancy adjusting ballast can be sealed at one end of a buoyant wood piece. A floating buoyancy adjusting weight is disclosed.
(2) In Japanese Utility Model Laid-Open Publication No. 64-41274 (hereinafter referred to as "B" publication), a fishing float is divided into a base for attachment to a road thread and a float main body in an upper half portion. There is disclosed a buoyancy adjusting float for fishing in which a recess for accommodating a buoyancy adjusting weight is formed along the axial direction and a connecting portion is formed in a press-fitting fitting structure.
(3) Japanese Utility Model Registration No. 3002092 (hereinafter referred to as “C”) discloses a float main body having a blind hole and a plurality of inserts having different weights removably mounted in the blind hole.

In addition, since the spring body is made of metal, it has a problem that it is corroded by seawater or the like and lacks durability. In addition, since the buoyancy adjusting weight has a specific structure which is substantially the same diameter as the diameter of the concave portion and is divided into a plurality of parts for buoyancy adjustment, if the buoyancy is lost at a fishing ground or the like, the float becomes unusable. Had the problem of becoming
(3) The structure disclosed in the publication No. C has a structure in which a plurality of columnar members and a plurality of sealing bolts are combined in accordance with the conditions of the fishing ground to adjust the buoyancy, but on board or in a narrow space. It is very difficult to combine parts on a rocky place, and there is a problem that the structure is complicated, the number of parts is large, and manufacturing is difficult. In addition, since the columnar members and the sealing bolts have a specific structure, there is a problem in that if the underwater or the like is accidentally dropped during fishing, the fishing rod cannot be used any longer and lacks durability.
(4) The structure described in the Japanese Patent Publication No. 4 has a structure in which the buoyancy is adjusted by press-fitting a compression part into the hollow portion at the center of the float, but it is difficult to adjust the weight and the buoyancy is not constant. Had problems.
(5) In the publication described in E, several types of straight rods must be prepared in order to adjust the buoyancy, and it is extremely difficult to adjust the straight rods according to the buoyancy. There was a problem that adjustment (positioning) of buoyancy was difficult.
(6) The one described in the above publication has a problem that the structure is complicated, the number of parts is large, and it is difficult to manufacture. Was.
As described above, all of the conventional floats have problems that they are difficult to manufacture, lack durability, are difficult to handle, and require time to adjust the buoyancy.
Further, in the case of a float that can use only a specially designed weight as in the past, the number of parts increases, it is necessary to manufacture it specially, and there is a problem that the cost is high and the versatility is lacking.
[0004]
The present invention solves the above-mentioned conventional problems. Since a lead ball such as a gun ball is used as the weight portion, it is possible to immediately cope with the situation of the fishing ground such as tide, weather, waves, and time, and to simplify the operation.

At the same time, the buoyancy can be immediately adjusted even on a narrow ship or a rocky place by a simple operation only by adjusting the number of weight portions.
When the float body is made of wood, foamed resin, etc., penetration of seawater into the interior is achieved by inserting and fixing a synthetic resin cylinder in the through hole and forming a synthetic resin coat layer. Thus, corrosion of the float body and changes in buoyancy can be prevented.
By using a lead ball such as a gun ball or a beetle as the weight part, it can be easily inserted, and immediately responds to tidal currents, weather, waves, and time without being affected by waves, and the buoyancy is reduced. Adjustment can be easily performed, and lead balls such as gun balls can be easily obtained anywhere and anytime, so that they are excellent in versatility and durability.
When the sealing portion is formed of a resilient material such as a rubber body or a synthetic resin, and a ridge is provided around the side wall portion in contact with the through-hole portion, the seawater can easily enter the through-hole portion with a simple configuration. Can be prevented from penetrating into Further, by providing a ridge or cap portion for gripping on the top portion, it can be easily opened and closed in a one-touch manner, and it is possible to prevent the sealing portion from being clogged with the through-hole portion and becoming unable to come off. .
Furthermore, it is not necessary to remove and replace the submerged fishing float from the line sequentially due to changes in the weather and the changing tide flow, and water-resistant paint made of red, orange, green, yellow, etc. The visibility can be changed according to the situation by changing only the sealing part coated with fluorescent paint on the surface, the luminous body fitted in the sealing part, or the sealing part with the cavity inside the luminous body and light emitting diode etc. Workability, operability and convenience can be improved.
Since the fishing line threading portion is formed to be rotatable, the fishing line can pass smoothly through the fishing line threading portion, and the buoyancy adjustment of the underwater sinking type fishing float by adjusting the number of weight portions is extremely effectively used. It is possible to cope with the initial biting of fish very well, and to obtain fishing results efficiently.
