Description

本発明は、ワームやフライ等のルアーに装着する錘に関し、特に、ルアーや錘が水底等に引っ掛かり難い根掛かり防止用のルアー用錘に関する。 The present invention relates to a weight attached to a lure such as a worm or a fly, and more particularly to a luer weight for preventing rooting in which the lure or weight is difficult to be caught on a water bottom or the like.

従来より、池や川もしくは海における魚釣りでは疑似餌が使用されることがあり、ルアーフィッシングと一般に呼ばれている。ルアーフィッシングにおいては、ルアーと呼ばれる各種の疑似餌（例えば、軟質プラスチックを素材とするワームや、釣り針に動物の毛や鳥の羽などを巻き付けて昆虫に見せかけるフライなど）を使用するが（特許文献１参照）、これらルアーをキャスト（投下）した際、そのままでは軽くて飛距離が出ないので、釣り糸とルアーとの間に錘を付けている。 Conventionally, pseudo bait is sometimes used for fishing in a pond, river or sea, and is generally called lure fishing. In lure fishing, various types of artificial baits called lures (for example, worms made of soft plastic, fly that wraps animal hair or bird wings around a fishhook to make them look like insects) are used (Patent Literature) 1), when these lures are cast (dropped), they are light as they are and do not fly, so a weight is attached between the fishing line and the lure.

ルアーに錘を付けてルアーを指定の場所にキャストすると、錘の重量でルアーが沈む。ルアーには疑似餌の他、掛止針（釣り針）が装着されており、この掛止針の向きは一定していないので、例えば、掛止針の折り曲げ先部が下を向いている場合には、川底などにある障害物に引っ掛かり易い（即ち、根掛かりし易い）という問題があった。また、従来のルアーは、錘に固定金具等で強固に固定されているので、仮にルアーの交換が可能であるとしても細かな作業が必要で交換しにくいという問題があった。 If you attach a weight to the lure and cast the lure to the specified location, the lure will sink by the weight of the weight. The lure is equipped with a pseudo bait and a hook (fishing hook), and the direction of the hook is not constant. For example, when the folding needle is bent downward Has a problem that it is easily caught on an obstacle at the bottom of the river (that is, it is easily rooted). In addition, since the conventional lure is firmly fixed to the weight with a fixing bracket or the like, there is a problem that even if the lure can be replaced, a fine work is required and the replacement is difficult.

そこで、特許文献２では、図４に示すように、比重が１より大きい材料からなって、下側が１００〜１５０度の角度で丸みを有して折れ曲がり、平面視して中央が幅広で前側及び後側に徐々に幅の狭くなった錘本体３１と、錘本体３１の前端３１ｃに設けられて、釣り糸１２の先端を結びつける金属製の環状糸止め金具３３と、錘本体３１の後端に設けられ、垂直面内で鉤状に屈曲しその折り曲げた部分が上位置にあって、掛止針１６付きのルアー１５を取り外し可能に止める鉤状掛止金具１４とを有する根掛かり防止用のルアー用錘３０の発明が開示されている。当該発明では、錘本体３１の下側がそのままの姿勢を維持して、回転をすることもなく水中を移動できるので、錘本体３１の後端にある鉤状掛止金具１４は、その折り曲げた部分が上向きとなり、水底にある障害物の他、水中を浮遊する障害物にも根掛かりしにくい。 Therefore, in Patent Document 2, as shown in FIG. 4, the specific gravity is made of a material larger than 1, and the lower side is bent with an angle of 100 to 150 degrees, and the center is wide in the plan view and the front side and A weight main body 31 that is gradually narrowed on the rear side, a metal annular thread stopper 33 that is provided at the front end 31 c of the weight main body 31 and connects the tip of the fishing line 12, and a rear end of the weight main body 31. A luer for preventing rooting having a hook-like hooking metal fitting 14 which is bent in a hook shape in the vertical plane and the bent portion is in the upper position and detachably holds the luer 15 with the hooking needle 16. An invention of the weight 30 is disclosed. In the present invention, the lower side of the weight main body 31 maintains the posture as it is and can move in the water without rotating. Therefore, the hook-shaped latch 14 at the rear end of the weight main body 31 is a bent portion. Is facing upwards, and it is difficult to root into obstacles floating in the water as well as obstacles at the bottom of the water.

しかしながら、図４に示すように、特許文献２に記載された根掛かり防止用のルアー用錘３０の場合、くの字状になった錘本体３１の湾曲凹部３１ａが木などの障害物２０に面している状態で、環状糸止め金具３３に結びつけられた釣り糸１２を引っ張ると、鉤状掛止金具１４に掛止された掛止針１６の先端部が湾曲凹部３１ａ側を向いているため、掛止針１６の先端部が障害物２０に引っ掛かってしまうということがあった。 However, as shown in FIG. 4, in the case of the luer weight 30 for preventing rooting described in Patent Document 2, the curved concave portion 31 a of the weight body 31 having a U-shape is formed on the obstacle 20 such as a tree. When the fishing line 12 tied to the annular thread stopper 33 is pulled in the facing state, the tip of the hook needle 16 hooked on the hook-shaped hook 14 is directed toward the curved recess 31a. In some cases, the tip of the latch needle 16 is caught by the obstacle 20.

本発明はかかる事情に鑑みてなされたもので、錘本体の湾曲凹部が障害物に面している状態で釣り糸を引っ張った場合でも、錘本体が回転して錘本体の湾曲凸部が障害物に接し、掛止針が障害物に引っ掛かることがない、根掛かり防止用のルアー用錘を提供することを目的とする。 The present invention has been made in view of such circumstances, and even when the fishing line is pulled in a state where the curved concave portion of the weight body faces the obstacle, the weight main body rotates and the curved convex portion of the weight main body becomes the obstacle. An object of the present invention is to provide a luer weight for preventing rooting in which the hook is not caught on an obstacle.

上記目的を達成するため、本発明は、比重が１より大きく、側面視して中間部で湾曲すると共に、平面視して中央が幅広で前側及び後側に徐々に幅の狭くなった錘本体と、前記錘本体の前側に設けられ、釣り糸の先端を結びつける環状糸止め金具と、前記錘本体の後側に設けられ、掛止針付きのルアーを引っ掛ける鉤状掛止金具とを有する根掛かり防止用のルアー用錘において、前記釣り糸と前記環状糸止め金具の接続ポイントが前記錘本体の湾曲凸部側に位置していることを特徴としている。
ここで、錘本体から見て釣り糸を結びつけた側を「前側」、ルアーを取り付けている側を「後側」と呼ぶことにする。 In order to achieve the above object, the present invention provides a weight body having a specific gravity greater than 1, curved in the middle as viewed from the side, wide at the center in plan view, and gradually narrowed toward the front and rear sides. And a ring-shaped clasp that is provided on the front side of the weight body and binds a tip of a fishing line, and a hook-shaped clasp that is provided on the rear side of the weight body and hooks a luer with a hook needle. The luer weight for prevention is characterized in that a connection point between the fishing line and the annular thread stopper is located on the curved convex portion side of the weight body.
Here, the side to which the fishing line is tied as viewed from the weight body is referred to as “front side”, and the side to which the lure is attached is referred to as “rear side”.

図３を用いて本発明の原理について説明する。図３（ａ）、（ｂ）はそれぞれ、錘本体１１、３１の湾曲凹部１１ａ、３１ａ側が障害物２０に面している状態で釣り糸を引っ張ったときの模式図である。この錘本体１１、３１の場合、平面視して中央が幅広で前側及び後側に徐々に幅が狭くなった形状をしているため、釣り糸を引っ張ると、図３のように、錘本体１１、３１は傾き、錘本体１１、３１の側面部が障害物２０と接触する。
本発明に係る根掛かり防止用のルアー用錘の場合、図３（ａ）に示すように、釣り糸（図示省略）と環状糸止め金具１３の接続ポイントＰ、即ち、力Ｆの作用点が錘本体１１の湾曲凸部１１ｂ側に位置しているので、釣り糸を力Ｆで水平方向（図では上方向）に引っ張った場合、錘本体１１と障害物２０との接触点Ｓを支点として、錘本体１１の湾曲凸部１１ｂが障害物２０に接する方向のモーメントＭが発生する。このため、本発明に係る根掛かり防止用のルアー用錘では、錘本体１１の湾曲凹部１１ａが障害物２０に面している状態で釣り糸を引っ張った場合でも、錘本体１１が水平面内で回転して錘本体１１の湾曲凸部１１ｂが障害物２０に接し、掛止針が障害物に引っ掛かることがない。 The principle of the present invention will be described with reference to FIG. FIGS. 3A and 3B are schematic views when the fishing line is pulled in a state where the curved concave portions 11a and 31a side of the weight main bodies 11 and 31 face the obstacle 20, respectively. In the case of the weight bodies 11 and 31, since the center is wide in plan view and the width gradually decreases toward the front side and the rear side, when the fishing line is pulled, the weight body 11 as shown in FIG. , 31 is tilted, and the side surfaces of the weight bodies 11, 31 come into contact with the obstacle 20.
In the case of the luer weight for preventing rooting according to the present invention, as shown in FIG. 3A, the connection point P between the fishing line (not shown) and the annular thread stopper 13, that is, the action point of the force F is the weight. Since it is located on the curved convex portion 11b side of the main body 11, when the fishing line is pulled in the horizontal direction (upward in the figure) with the force F, the weight is set with the contact point S between the weight main body 11 and the obstacle 20 as a fulcrum A moment M is generated in a direction in which the curved convex portion 11b of the main body 11 is in contact with the obstacle 20. Therefore, in the luer weight for preventing rooting according to the present invention, even when the fishing line is pulled while the curved concave portion 11a of the weight body 11 faces the obstacle 20, the weight body 11 rotates in a horizontal plane. Thus, the curved convex portion 11b of the weight main body 11 is in contact with the obstacle 20, and the latch needle is not caught by the obstacle.

一方、特許文献２に記載された根掛かり防止用のルアー用錘の場合、図３（ｂ）に示すように、錘本体３１の前端３１ｃの位置に、釣り糸と環状糸止め金具３３の接続ポイントＰが位置しているため、釣り糸（図示省略）を力Ｆで水平方向（図では上方向）に引っ張った場合、接続ポイントＰと、錘本体３１と障害物２０との接触点Ｓは、力Ｆの作用線上に位置することになり、接触点Ｓを支点として、錘本体３１の湾曲凸部３１ｂが障害物２０に接する方向のモーメントＭは発生しない。従って、錘本体３１が回転せず、掛止針が障害物に引っ掛かることになる。 On the other hand, in the case of the luer weight for preventing rooting described in Patent Document 2, as shown in FIG. 3 (b), the connection point between the fishing line and the annular thread stopper 33 at the position of the front end 31 c of the weight body 31. Since P is located, when the fishing line (not shown) is pulled in the horizontal direction (upward in the figure) with force F, the contact point S between the connection point P and the weight body 31 and the obstacle 20 is The moment M in the direction in which the curved convex portion 31b of the weight main body 31 is in contact with the obstacle 20 is not generated with the contact point S as a fulcrum. Therefore, the weight main body 31 does not rotate, and the latching needle is caught by the obstacle.

また、本発明に係る根掛かり防止用のルアー用錘では、釣り糸を引っ張った場合、錘本体が水平面内で回転して錘本体の湾曲凸部が障害物に接するため、鉤状掛止金具の鉤状に屈曲した部位は、錘本体の湾曲凹部側に位置していることが好ましい。これにより、鉤状掛止金具が障害物に引っ掛かることがなくなる。なお、本発明では、掛止針の先端部も、錘本体の湾曲凹部側に位置していることを想定している。 Further, in the luer weight for preventing rooting according to the present invention, when the fishing line is pulled, the weight main body rotates in a horizontal plane and the curved convex portion of the weight main body contacts the obstacle. The part bent in a bowl shape is preferably located on the curved concave side of the weight body. As a result, the hook-shaped hook is not caught by an obstacle. In the present invention, it is assumed that the distal end portion of the latch needle is also located on the curved concave portion side of the weight main body.

また、本発明に係る根掛かり防止用のルアー用錘では、前記錘本体は、側面視して胃袋形状とされていてもよい。
当該構成では、ルアー用錘全体が滑らかに形成されるので、水に対する抵抗が減少し、水を不必要に攪乱することがない。 In the luer weight for preventing rooting according to the present invention, the weight main body may have a stomach bag shape in a side view.
In this configuration, since the entire lure weight is formed smoothly, resistance to water is reduced, and water is not unnecessarily disturbed.

また、本発明に係る根掛かり防止用のルアー用錘では、前記環状糸止め金具は、前記錘本体の前端から延出し、前記錘本体の湾曲凸部側に折れ曲がっていてもよい。これにより、釣り糸と環状糸止め金具の接続ポイントは、錘本体の湾曲凸部側に位置することになる。 In the luer weight for preventing rooting according to the present invention, the annular thread stopper may extend from the front end of the weight body and bend toward the curved convex portion of the weight body. As a result, the connection point between the fishing line and the annular thread stopper is located on the curved convex portion side of the weight body.

本発明に係る根掛かり防止用のルアー用錘では、釣り糸と環状糸止め金具の接続ポイントが錘本体の湾曲凸部側に位置しているので、錘本体の湾曲凹部が障害物に面している状態で釣り糸を引っ張った場合でも、錘本体が回転して錘本体の湾曲凸部が障害物に接し、掛止針が障害物に引っ掛かることはない。 In the luer weight for preventing rooting according to the present invention, since the connection point of the fishing line and the annular thread stopper is located on the curved convex portion side of the weight main body, the curved concave portion of the weight main body faces the obstacle. Even when the fishing line is pulled in a state where the fishing line is pulled, the weight main body rotates, the curved convex portion of the weight main body comes into contact with the obstacle, and the hooking needle is not caught by the obstacle.

続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
図１及び図２に示すように、本発明の一実施の形態に係る根掛かり防止用のルアー用錘１０は、比重が１より大きい材料（例えば、鉛、鉛合金）からなる錘本体１１と、錘本体１１の前端１１ｃに設けられた環状糸止め金具１３と、錘本体１１の後端に設けられた鉤状掛止金具１４とを有し、鉤状掛止金具１４には掛止針１６付きのルアー１５が取り付けられている。 Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
As shown in FIGS. 1 and 2, a luer weight 10 for preventing rooting according to an embodiment of the present invention includes a weight body 11 made of a material (for example, lead, lead alloy) having a specific gravity greater than 1. , An annular thread stopper 13 provided at the front end 11 c of the weight body 11, and a hook-shaped hook 14 provided at the rear end of the weight body 11. A luer 15 with 16 is attached.

錘本体１１は、側面視して中間部で丸み１９をもって湾曲し、人の胃袋形状又は上下方向から少し押圧して扁平となった胃袋形状をしている。錘本体１１の湾曲凸部１１ｂは、前側傾斜面２１とこれに丸み１９をもって繋がる下側面２２とを有し、前側傾斜面２１と下側面２２が成す角度αは約１００〜１５０度とされている。また、錘本体１１は、図２に示すように、平面視して前側から中央に向かう角度βは３０〜６０度、平面視して後側から中央に向かう角度γは３０〜５５度となっている。即ち、平面視して中央が幅広で前側及び後側に徐々に幅が狭くなっており、その断面は全体として軸対称の楕円形状（又は扁平形状）となっている。 The weight main body 11 is curved with a roundness 19 at the middle portion when viewed from the side, and has a stomach bag shape that is flattened by being slightly pressed from a person in the vertical direction. The curved convex portion 11b of the weight body 11 has a front inclined surface 21 and a lower side surface 22 connected to the front inclined surface 21 with a roundness 19, and an angle α formed by the front inclined surface 21 and the lower side surface 22 is about 100 to 150 degrees. Yes. Further, as shown in FIG. 2, the weight body 11 has an angle β of 30 to 60 degrees from the front side to the center in a plan view, and an angle γ from the rear side to the center in a plan view of 30 to 55 degrees. ing. That is, in the plan view, the center is wide and the width is gradually narrowed to the front side and the rear side, and the cross section is an axisymmetric elliptical shape (or flat shape) as a whole.

錘本体１１内には、金属線の一例であるステンレス線１７（鋼線であってもよい。）が、錘本体１１の長手方向に挿入されている。ステンレス線１７の一方の端部は、錘本体１１の前端１１ｃから延出する環状糸止め金具１３とされ、環状糸止め金具１３は錘本体１１の湾曲凸部１１ｂ側に折れ曲がっている。一方、ステンレス線１７の他方の端部は、錘本体１１の後端から延出する鉤状掛止金具１４とされている。 A stainless steel wire 17 (which may be a steel wire), which is an example of a metal wire, is inserted into the weight main body 11 in the longitudinal direction of the weight main body 11. One end of the stainless steel wire 17 is an annular thread stopper 13 extending from the front end 11 c of the weight body 11, and the annular thread stopper 13 is bent toward the curved protrusion 11 b of the weight body 11. On the other hand, the other end of the stainless steel wire 17 is a hook-shaped latch 14 that extends from the rear end of the weight body 11.

錘本体１１の前端１１ｃに設けられた環状糸止め金具１３は、例えば、短径が１．５〜２．５ｍｍ、長径が２〜３．５ｍｍの長円形（又は楕円状）とされ、直径が例えば、０．９〜１．２ｍｍのステンレス線１７を折り曲げてリング状に形成されている。 The annular thread stopper 13 provided at the front end 11c of the weight body 11 is, for example, an ellipse (or an ellipse) having a short diameter of 1.5 to 2.5 mm and a long diameter of 2 to 3.5 mm. For example, a stainless wire 17 of 0.9 to 1.2 mm is bent and formed into a ring shape.

一方、錘本体１１の後端に設けられた鉤状掛止金具１４は、ステンレス線１７が錘本体１１の後端から突出し、垂直面内で鉤状に屈曲している。そして、折り曲げた部位が湾曲凹部１１ａ側にあって、更にその先側１４ａは半円状（即ち、円弧状）となって後方（又は上向き）に折り返されている。この鉤状掛止金具１４の鉤出入口２３の開口幅ｗは、鉤状掛止金具１４の内側の幅ｚより狭く（例えば、ｗ＝ｚ／４〜ｚ／２）なって、鉤状掛止金具１４に掛止された掛止針１６が容易に外れないようになっている。なお、本実施の形態においては、鉤状部の曲率半径は１．５〜３．５ｍｍ程度となっている。また、環状糸止め金具１３も、鉤状掛止金具１４と同様、垂直面に沿って曲げられている。 On the other hand, in the hook-shaped latch 14 provided at the rear end of the weight main body 11, the stainless steel wire 17 protrudes from the rear end of the weight main body 11 and is bent into a hook shape in the vertical plane. The bent portion is on the curved concave portion 11a side, and the front side 14a thereof is semicircular (that is, arcuate) and folded back (or upward). The opening width w of the saddle door 23 of the hook-shaped hook 14 is narrower than the width z inside the hook-shaped hook 14 (for example, w = z / 4 to z / 2). The latch needle 16 latched by the metal fitting 14 is not easily removed. In the present embodiment, the radius of curvature of the bowl-shaped portion is about 1.5 to 3.5 mm. The annular thread stopper 13 is also bent along the vertical plane, like the hook-shaped stopper 14.

本実施の形態におけるルアー１５は、掛止針１６と、疑似餌の一例であるワーム１８とを備えている。掛止針１６の基端部には、掛止リング２４が設けられている。この掛止リング２４の内径は１．０〜１．５ｍｍ（なお、鉤状掛止金具１４の線径の１．１〜２倍であってもよい。）とされ、鉤状掛止金具１４に着脱可能な構造となっている。また、掛止針１６は、掛止リング２４を除く部分が、垂直面内で鉤状に折り曲げられており、掛止リング２４はこの垂直面と直交する平面内で環状に折り曲げられている。 The lure 15 in the present embodiment includes a latch needle 16 and a worm 18 that is an example of a pseudo bait. A latch ring 24 is provided at the proximal end portion of the latch needle 16. The inner diameter of the retaining ring 24 is 1.0 to 1.5 mm (which may be 1.1 to 2 times the wire diameter of the collar-shaped latching metal 14). It is structured to be detachable. Further, the portion of the latching needle 16 excluding the latching ring 24 is bent in a hook shape in a vertical plane, and the latching ring 24 is bent in an annular shape in a plane orthogonal to the vertical plane.

従って、この掛止針１６を鉤状掛止金具１４に装着した場合、掛止針１６は垂直面内にあって、掛止針１６の先端部は掛止針１６の中心（重心）以下に対して上位にある。
ワーム１８は、本実施の形態では、掛止針１６の基側近くに取り付けられているが、鉤状掛止金具１４に直接装着することもできる。 Therefore, when the latching needle 16 is attached to the hook-shaped latching bracket 14, the latching needle 16 is in a vertical plane, and the tip of the latching needle 16 is below the center (center of gravity) of the latching needle 16. On the other hand.
In the present embodiment, the worm 18 is attached near the proximal side of the latch needle 16, but can be directly attached to the hook-shaped latch 14.

このようにして組み立てたルアー１５付きの根掛かり防止用のルアー用錘１０の環状糸止め金具１３に釣り糸１２の先端を結びつけて、ルアー１５付きの根掛かり防止用のルアー用錘１０を所定のポイントにキャストする。そして、釣り糸１２を引っ張ると、錘本体１１の前側傾斜面２１が揚力を受け、引っ張る速度が一定値を超えると水中を泳ぐように移動し、ワーム１８もこれに応じて水中を泳ぐことになる。
また、錘本体１１の湾曲凹部１１ａが障害物に面している状態で釣り糸１２を引っ張った場合でも、釣り糸１２と環状糸止め金具１３の接続ポイントＰが錘本体１１の湾曲凸部１１ｂ側に位置しているので、錘本体１１が回転して錘本体１１の湾曲凸部１１ｂが障害物に接し、掛止針１６が障害物に引っ掛かることはない。 The tip of the fishing line 12 is tied to the annular thread stopper 13 of the luer weight 10 for preventing rooting with the luer 15 assembled in this way, and the luer weight 10 for preventing rooting with the luer 15 is attached to the predetermined thread. Cast to points. When the fishing line 12 is pulled, the front inclined surface 21 of the weight body 11 receives lift, and when the pulling speed exceeds a certain value, it moves so as to swim underwater, and the worm 18 also swims underwater accordingly. .
Even when the fishing line 12 is pulled in a state where the curved concave portion 11a of the weight body 11 faces an obstacle, the connection point P between the fishing line 12 and the annular thread stopper 13 is on the curved convex portion 11b side of the weight main body 11. Therefore, the weight main body 11 does not rotate, the curved convex portion 11b of the weight main body 11 comes into contact with the obstacle, and the latch needle 16 is not caught by the obstacle.
