Description

本発明は、投げ釣り用錘に関するものであり、特に、道糸の先端近傍に天秤を介して取り付けられる飛行機型の錘に関するものである。 The present invention relates to a weight for throwing fishing, and more particularly to an airplane-shaped weight attached to the vicinity of the tip of a road thread via a balance.

従来から、投げ釣り用の錘として紡錘型の錘が広く知られている。投げ釣り用錘の第一の目的は遠投であり、錘を付けた仕掛けをより遠く、かつ、狙った地点にできるだけ正確に着水させることが、釣果をより向上させることができる。従来の紡錘型の錘を遠投するためには、単純には、錘の重量を重くすればよい。しかしながら、投げ釣りでは、人手で錘（仕掛け）を投げるので、錘が重すぎると、投げるたびに相当の労力が必要であり、そもそも、極端に重い錘は、遠くまで投げることができない。また、錘が重くなれば、アタリの感度が悪くなる虞がある。このため、近年では、錘に翼を取り付けて、翼に発生する揚力を利用して、従来の紡錘型の錘より遠くへ飛ばすことができる翼付きの錘が提案されている。 Conventionally, a spindle-shaped weight has been widely known as a weight for throwing fishing. The primary purpose of the weight for throwing fishing is long-distance casting, and it is possible to further improve the fishing result by landing the device with the weight farther and as accurately as possible at the target point. In order to cast a conventional spindle-shaped weight over a long distance, the weight of the weight may simply be increased. However, in throwing fishing, a weight (device) is thrown manually, so if the weight is too heavy, considerable effort is required each time it is thrown, and in the first place, an extremely heavy weight cannot be thrown far. Further, if the weight becomes heavy, the sensitivity of Atari may deteriorate. For this reason, in recent years, a weight with a wing has been proposed in which a wing is attached to the weight and the lift generated in the wing can be used to fly the weight farther than the conventional spindle-shaped weight.

また、投げ釣りにおいては、仕掛けが絡まないように天秤を用いることが一般的である。天秤には、Ｌ字型天秤、ジェット天秤、スパイク天秤等があるが、この中では、Ｌ字型天秤が、遠投性に優れ、仕掛けが絡みにくいことが知られている。Ｌ字型天秤は、例えば、水平軸と垂直軸とを備えたいわゆるＬ字型に形成された天秤であって、錘（仕掛け）の飛行中、水平軸が錘（仕掛け）の飛行線に沿い、垂直軸が、この飛行線に直交するように、水平軸と垂直軸との連結点が錘に固着されたものが知られている。 Also, in throwing fishing, it is common to use a balance so that the gimmicks do not get entangled. The balance includes an L-shaped balance, a jet balance, a spike balance, and the like. Among them, the L-shaped balance is known to have excellent long-distance castability and to prevent entanglement of gimmicks. The L-shaped balance is, for example, a balance formed in a so-called L-shape having a horizontal axis and a vertical axis, and the horizontal axis follows the flight line of the weight (device) during the flight of the weight (device). , It is known that the connection point between the horizontal axis and the vertical axis is fixed to the weight so that the vertical axis is orthogonal to this flight line.

以下、従来提案されている投げ釣り用の錘であって、翼を備えた構成のものを示す。
特許文献１には、「（イ）針金の部分が長くて投げづらかった。（ロ）おもりと針金の組合せのため、飛行中の空気抵抗が大きかった。（ハ）おもり回収時の浮力が弱く、根掛かりしやすかった。（ニ）釣人とハリの間に針金が介在し、釣り糸が直線に繋がらずアタリが判りにくかった」（段落「０００３」参照。）という「欠点」を解決することを目的とした「中空パイプ（１）の片方を中通しおもり（２）の中に貫設し、中空パイプ（１）のもう一方に尾翼（３）を３枚あるいは４枚、中空パイプ（１）を中心に放射状に設けたことを特徴とする、つり用の尾翼付き遊動投げおもり」（「請求項１」参照。）という発明が記載されている。また、特許文献１には、発明の効果として「サイズがコンパクトなため投げ易く、かつ、尾翼の効果で飛行時の空気抵抗が少なくなり飛距離が伸びる。さらに、おもり回収時には尾翼に水の揚力が働き、素早く浮上する。また、道糸と仕掛けが直結しているためアタリが判り易い」（段落「０００６」参照。）と記載されている。 Hereinafter, a weight for throwing fishing that has been conventionally proposed and having a wing configuration will be shown.
Patent Document 1 states, "(a) The wire part was long and difficult to throw. (B) Due to the combination of the weight and the wire, the air resistance during flight was large. (C) The buoyancy at the time of collecting the weight was weak. It was easy to take root. (D) A wire was inserted between the fisherman and the tension, and the fishing thread was not connected in a straight line, making it difficult to understand the weight. ”(See paragraph“ 0003 ”.) The target "one of the hollow pipes (1) is pierced into the weight (2), and three or four tail wings (3) are inserted into the other of the hollow pipes (1), and the hollow pipe (1). There is described an invention of a floating throw weight with a tail wing for fishing (see "Claim 1"), which is characterized in that the weight is provided radially around the center. Further, in Patent Document 1, as an effect of the invention, "it is easy to throw because of its compact size, and the effect of the tail wing reduces the air resistance during flight and extends the flight distance. Further, the lift of water on the tail wing when collecting the weight. Works and ascends quickly. In addition, it is easy to understand the attack because the road thread and the device are directly connected "(see paragraph" 0006 ").

また、特許文献２には、「遠投する際に距離を稼げる上、方向性もよく、海面に着水してから、手元に引き寄せるまで視認するのが容易で、かつ魚信を察知可能なサヨリ釣用遠投浮き及びサヨリ釣用遠投仕掛けを提供すること」（段落「０００４」参照。）を目的とした「両端が次第に細くなった円柱体に複葉の翼が軸支されたサヨリ釣用遠投浮きであって、前記円柱体は、海水よりも比重が小さい浮力生成部と海水よりも比重が大きい錘力生成部とを有し、前記翼は、前記浮力生成部の端から所定長突出した軸に回転自在、かつ移動自在に軸支されたことを特徴とするサヨリ釣用遠投浮き」（段落「請求項１」参照。）という考案が記載され、また、特許文献２には、考案の効果として「投げ竿により遠くまで投げることができるうえ、海水に着水したときに翼を上に向けて浮遊するので、遠方からでも視認することができる。また、ハリスを海面下数十センチの範囲内に配置することができるので、岸辺から遠く離れた海面近傍を回遊する大型のサヨリを釣ることができる」（段落「０００７」参照。）と記載されている。 In addition, Patent Document 2 states, "In addition to gaining a distance when casting a long distance, it has a good direction, and it is easy to visually recognize from the time it lands on the surface of the sea until it is drawn to the hand, and it is possible to detect fish. "Providing a long-throw float for halfbeak fishing and a long-throw gimmick for halfbeak fishing" (see paragraph "0004"). The columnar body has a buoyancy generating portion having a specific gravity smaller than that of seawater and a weight force generating portion having a specific gravity larger than that of seawater. A device called "long-distance fishing float for halfbeak fishing" (see paragraph "claim 1"), which is characterized in that it is rotatably and movably supported by a long protruding shaft, is also described in Patent Document 2. As an effect of the idea, "It can be thrown far away by a throwing rod, and when it lands in seawater, it floats with its wings facing up, so it can be seen from a distance. Also, Harris can be seen from a distance. Since it can be placed within a range of several tens of centimeters, it is possible to catch a large halfbeak that roams near the sea surface far from the shore "(see paragraph" 0007 ").

しかしながら、特許文献１に記載の発明の「つり用の尾翼付き遊動投げおもり」は、紡錘形状の「中通しおもり（２）」の後端部に「尾翼（３）」を付けた構成であるので、揚力の効果がそれほど期待できず、従来の紡錘型の錘よりは「飛距離が伸び」たとしても、飛行軌跡は自然放物線（いわゆる、「山なり」）に近い軌跡を描くものと推量され、したがって、飛行ロスがあるものと思われる。また、特許文献１の図２の構成では、「糸止め（４）」が「中通しおもり（２）」の先端部直近にあるので、飛行中に「仕掛け（５）」が、「中通しおもり（２）」、「尾翼（３）」、「道糸（８）」に絡む虞がある。特許文献１の図３に記載の構成でも同様である。 However, the "floating throw weight with tail wing" of the invention described in Patent Document 1 has a configuration in which a "tail wing (3)" is attached to the rear end of a spindle-shaped "center weight (2)". Therefore, the effect of lift cannot be expected so much, and even if the flight distance is "extended" compared to the conventional spindle-shaped weight, it is estimated that the flight trajectory draws a trajectory close to a natural parabolic line (so-called "mountain"). Therefore, it seems that there is a flight loss. Further, in the configuration of FIG. 2 of Patent Document 1, since the "thread stopper (4)" is located near the tip of the "intermediate weight (2)", the "device (5)" is replaced with the "intermediate thread" during flight. There is a risk of getting entangled in the "weight (2)", "tail (3)", and "road thread (8)". The same applies to the configuration shown in FIG. 3 of Patent Document 1.

また、特許文献２の図１０には、「サヨリ釣用遠投浮き１」の飛行軌跡が、直線的であるように記載されているけれども、「サヨリ釣用遠投浮き１」は、「円柱体２」の後端部に「プロペラ４」を「軸３」で連結した構成であるので、「プロペラ４」の揚力の効果がそれほど期待できず、特許文献１と同様に、実際の飛行軌跡は自然放物線（いわゆる、「山なり」）に近い軌跡を描くものと推量され、したがって、飛行ロスがあるものと思われる。 Further, although FIG. 10 of Patent Document 2 describes that the flight trajectory of the “long-throw float 1 for sayori fishing” is linear, the “long-throw float 1 for sayori fishing” is a “cylinder”. Since the "propeller 4" is connected to the rear end of the "body 2" by the "axis 3", the lift effect of the "propeller 4" cannot be expected so much, and the actual flight trajectory is the same as in Patent Document 1. Is presumed to follow a trajectory close to a natural parabola (so-called "mountain"), and is therefore thought to have flight loss.

さらに、特許文献１に記載の発明には、「中通しおもり２」、「尾翼３」の取付け位置を調節する構成が設けられておらず、また、特許文献２に記載の考案には、「プロペラ４」、「錘力生成部６」の取付け位置を調節する構成が設けられていない。このため、特許文献１記載の発明および特許文献２記載の考案は、同一の胴体部で錘の重さを変えると飛距離に大きなバラツキを生じてしまう。 Further, the invention described in Patent Document 1 is not provided with a configuration for adjusting the mounting positions of the "intermediate weight 2" and the "tail wing 3", and the invention described in Patent Document 2 includes " There is no configuration for adjusting the mounting positions of the "propeller 4" and the "weight force generating unit 6". Therefore, in the invention described in Patent Document 1 and the invention described in Patent Document 2, if the weight of the weight is changed in the same body portion, the flight distance will vary greatly.

そこで、本発明は、投げ釣りの際に、飛行軌跡の直線部分を多くして飛行ロスを低減し、飛距離を延ばすことができる投げ釣り用飛行機型錘を提供することを目的とする。 Therefore, an object of the present invention is to provide an airplane-type weight for throwing fishing capable of increasing the number of straight portions of the flight trajectory to reduce flight loss and extend the flight distance during throwing fishing.

また、本発明は、錘の重量を軽減し、投げ釣りの際に労力を要せず簡単に遠投できる投げ釣り用飛行機型錘を提供することを目的とする。 Another object of the present invention is to provide an airplane-type weight for throwing fishing, which reduces the weight of the weight and allows easy long-distance casting without requiring labor during throwing fishing.

また、本発明は、左翼部取付け位置調節用の構成と、右翼部取付け位置調節用の構成と、垂直翼部取付け位置調節用の構成とが形成された胴体部を備えた投げ釣り用飛行機型錘を提供することを目的とする。 Further, the present invention is an airplane type for throwing fishing provided with a fuselage portion in which a configuration for adjusting the mounting position of the left wing portion, a configuration for adjusting the mounting position of the right wing portion, and a configuration for adjusting the mounting position of the vertical wing portion are formed. The purpose is to provide a weight.

In order to achieve the above object, the invention according to claim 1 includes a longitudinal body portion, left and right wing portions attached to the left and right sides of the body portion along the longitudinal direction, and an upper portion of the body portion. Throw fishing provided with a vertical wing portion vertically attached along the longitudinal direction, a weight portion attached vertically to the lower part of the fuselage portion, and a balance connecting portion attached to the rear end portion of the fuselage portion. A left wing mounting position adjusting groove, a right wing mounting position adjusting groove, a vertical wing mounting position adjusting groove, and a weight mounting groove are formed in the body portion of the aircraft-type weight. parts are mounted and fixed in a pre-Symbol state left part is adjusted to the mounting position on the mounting position adjusting groove, the right wing portion is fixed in a state of being adjusted to the mounting position on the right wing portion mounting position adjusting groove The left wing and the right wing are attached, and the attachment positions of the left wing and the right wing are higher than the central axis of the fuselage, and the vertical wing is fixedly attached to the vertical wing attachment position adjusting groove, and the weight is attached.

本発明の投げ釣り用飛行機型錘１は、特に図１に示されるように、いわゆる飛行機型の構成をなしており、長手形状の胴体部２と、胴体部２の左右に長手方向に沿って取付けられた左翼部３および右翼部４、胴体部２の上部に長手方向に沿って垂直に取付けられた垂直翼部５と、胴体部２の下部に鉛直方向に取付けられた錘部６と、胴体後端部２ｃに取付けられた天秤連結部７とを備えている。 As shown in FIG. 1, the airplane-shaped weight 1 for throwing fishing of the present invention has a so-called airplane-shaped structure, and has a long-shaped body portion 2 and the left and right sides of the body portion 2 along the longitudinal direction. The left wing portion 3 and the right wing portion 4 attached, the vertical wing portion 5 vertically attached to the upper part of the fuselage portion 2 along the longitudinal direction, and the weight portion 6 attached vertically to the lower part of the fuselage portion 2, It is provided with a balance connecting portion 7 attached to the rear end portion 2c of the fuselage.

発明を分かりやすくするために、図７（ａ）に示すように、胴体部２は、例えばプラスチックのような合成樹脂製で形成された側面視矩形の円柱状部材８を削成して形成されているものとする。胴体部２を削成する前の円柱状部材８の中心軸線をＣＬとする。中心軸線ＣＬは、円柱状部材８の中心を通る軸線であり、円柱状部材８の側面から等距離ｍにある。胴体先端部２ａは、この中心軸線ＣＬよりも上側に位置するように形成されている。胴体部２は、前部と後部とが流線型を呈するように形成されている。前部を流線型にするのは、キャスティング時の投げ釣り用飛行機型錘１の飛行中の空気抵抗を小さくするためである。後部を流線型にするのは、サーフトロールのリトリーブ時に、投げ釣り用飛行機型錘１の空気抵抗を小さくし、かつ、水面を跳ねやすくするためである。胴体部２は、長手方向中心Ｃ２より後方に円柱状部材８と同径の最大径部２ｂが形成され、最大径部２ｂから胴体先端部２ａに近づくにつれて徐々に縮径され、また、最大径部２ｂから胴体後端部２ｃに近づくにつれて徐々に縮径されて形成されている。なお、最大径部２ｂから胴体後端部２ｃに近づくにつれて、一定区間は最大径部２ｂと同径で、その後徐々に縮径され、また、最大径部２ｂから胴体後端部２ｃに近づくにつれて、一定区間は最大径部と同径で、その後徐々に縮径されて形成された構成でもよい。 In order to make the invention easy to understand, as shown in FIG. 7A, the body portion 2 is formed by cutting a rectangular columnar member 8 having a rectangular side view, which is made of a synthetic resin such as plastic. It is assumed that Let CL be the central axis of the columnar member 8 before cutting the body portion 2. The central axis CL is an axis that passes through the center of the columnar member 8 and is equidistant m from the side surface of the columnar member 8. The fuselage tip portion 2a is formed so as to be located above the central axis CL. The body portion 2 is formed so that the front portion and the rear portion exhibit a streamlined shape. The reason why the front part is streamlined is to reduce the air resistance during flight of the airplane-type weight 1 for throwing fishing during casting. The reason why the rear part is streamlined is to reduce the air resistance of the airplane-type weight 1 for throwing fishing and to make it easier for the water surface to bounce when retrieving the surf roll. The body portion 2 has a maximum diameter portion 2b having the same diameter as the columnar member 8 formed behind the center C2 in the longitudinal direction, and is gradually reduced in diameter as it approaches the fuselage tip portion 2a from the maximum diameter portion 2b, and also has a maximum diameter. The diameter is gradually reduced from the portion 2b toward the rear end portion 2c of the fuselage. As the maximum diameter portion 2b approaches the rear end portion 2c of the fuselage, a certain section has the same diameter as the maximum diameter portion 2b, and then the diameter is gradually reduced, and as the maximum diameter portion 2b approaches the rear end portion 2c of the fuselage. , The fixed section may have the same diameter as the maximum diameter portion, and then gradually reduced in diameter.

胴体部２の左側面には、胴体先端部２ａ近傍から胴体後端部２ｃまで中心軸線ＣＬに対して平行に、所定深さの左翼部取付け位置調節溝３ａが形成され、胴体部２の右側面には、胴体先端部２ａ近傍から胴体後端部２ｃまで中心軸線ＣＬに対して平行に、所定深さの右翼部取付け位置調節溝４ａが形成されている。左翼部取付け位置調節溝３ａの溝長さは、左翼部３の翼根弦長よりも長く形成され、右翼部取付け位置調節溝４ａの溝長さは、右翼部４の翼根弦長よりも長く形成されているので、左翼部３、右翼部４を、それぞれ、左翼部取付け位置調節溝３ａ、右翼部取付け位置調節溝４ａに取り付ける際に、錘部６の重さに応じて、取付け位置を前後に調節して取り付けることができるように構成されている。 On the left side surface of the fuselage portion 2, a left wing portion mounting position adjusting groove 3a having a predetermined depth is formed parallel to the central axis CL from the vicinity of the fuselage tip portion 2a to the fuselage rear end portion 2c, and the right side of the fuselage portion 2 is formed. On the surface, a right wing mounting position adjusting groove 4a having a predetermined depth is formed parallel to the central axis CL from the vicinity of the fuselage tip 2a to the fuselage rear end 2c. The groove length of the left wing mounting position adjusting groove 3a is formed longer than the wing root chord length of the left wing 3, and the groove length of the right wing mounting position adjusting groove 4a is longer than the wing root chord length of the right wing 4. Since it is formed to be long, when the left wing portion 3 and the right wing portion 4 are attached to the left wing portion mounting position adjusting groove 3a and the right wing portion mounting position adjusting groove 4a, respectively, the mounting position is adjusted according to the weight of the weight portion 6. It is configured so that it can be attached by adjusting it back and forth.

胴体部２の上部には、胴体先端部２ａ近傍から胴体後端部２ｃまで、所定深さの垂直翼部取付け位置調節部５ａが形成されている。垂直翼部取付け位置調節部５ａの溝長さは、垂直翼部５の翼根弦長よりも長く形成されているので、垂直翼部５を、垂直翼部取付け位置調節溝５ａに取り付ける際に、錘部６の重さに応じて、取付け位置を前後に調節して取り付けることができるように構成されている。 A vertical wing attachment position adjusting portion 5a having a predetermined depth is formed on the upper portion of the fuselage portion 2 from the vicinity of the fuselage tip portion 2a to the fuselage rear end portion 2c. Since the groove length of the vertical wing portion mounting position adjusting portion 5a is formed longer than the wing root chord length of the vertical wing portion 5, when the vertical wing portion 5 is mounted in the vertical wing portion mounting position adjusting groove 5a, , The mounting position can be adjusted back and forth according to the weight of the weight portion 6 for mounting.

胴体部２の下部には、胴体先端部２ａ近傍から胴体部２の略中央部まで、所定深さの錘部取付け溝６ａが形成されている。錘部取付け溝６ａの溝長さは、錘部６が取付け可能な長さに形成されている。また、錘部取付け溝６ａの溝深さは、前方が深く、後方にいくにしたがって浅くなるように形成されている。これは、錘部６を錘部取付け溝６ａに取付けた際に、投げ釣り用飛行機型錘１の重心が、前方に位置するようにするためである。
なお、錘部取付け溝６ａの溝長さを、錘部６の錘取付け部６ｂよりも長く形成し、錘部６を錘部取付け溝６ａに取り付ける際に、投げ釣り用飛行機型錘１の重心位置を調節するために、錘部６の取付け位置を前後に調節して取り付けることができるように構成してもよい。このような構成にするときは、「錘部取付け溝６ａ」を、「錘部取付け位置調節溝６ａ」と表現してよい。 A weight portion mounting groove 6a having a predetermined depth is formed in the lower portion of the body portion 2 from the vicinity of the body tip portion 2a to the substantially central portion of the body portion 2. The groove length of the weight portion mounting groove 6a is formed so that the weight portion 6 can be mounted. Further, the groove depth of the weight portion mounting groove 6a is formed so as to be deep in the front and shallower toward the rear. This is to ensure that the center of gravity of the throw fishing airplane-shaped weight 1 is located forward when the weight portion 6 is attached to the weight portion mounting groove 6a.
The groove length of the weight portion mounting groove 6a is formed longer than the weight mounting portion 6b of the weight portion 6, and when the weight portion 6 is attached to the weight portion mounting groove 6a, the center of gravity of the airplane-shaped weight 1 for throwing fishing is formed. In order to adjust the position, the mounting position of the weight portion 6 may be adjusted back and forth so that the weight portion 6 can be mounted. In such a configuration, the "weight portion mounting groove 6a" may be expressed as the "weight portion mounting position adjusting groove 6a".

胴体後端部２ｃには、投げ釣り時に天秤が連結される天秤連結部７が取付けられている。本発明においては、天秤連結部７には、垂直アームと水平アームとの交点部に回転部を備えた半誘導式のＬ字型天秤を連結することが好ましい。これは、キャスティング時に、仕掛けが絡まないようにするためと、Ｌ字型天秤が回転した際に、投げ釣り用飛行機型錘１が連動して回転しないようにするためである。回転部を有しないＬ字型天秤を使用する場合は、Ｌ字型天秤と天秤連結部７との間に「より戻し」（「スイベル」、または、「サルカン」ともいう。）を介在させてもよい。これにより、飛行中に、連結された天秤が回転しても、投げ釣り用飛行機型錘１は、安定した飛行姿勢を維持し、飛距離を向上することができる。
なお、天秤連結部７との間に回転部を有しない半誘導式のＬ字型天秤であっても、従来技術よりは飛距離は増加する。また、胴体部２は、合成樹脂製の円柱状部材８を切削して、所定の形状に形成することを説明したが、削成技術代えて、周知の樹脂成形技術を用いて、上述した形状に成形することもできる。 A balance connecting portion 7 to which a balance is connected at the time of throwing fishing is attached to the rear end portion 2c of the fuselage. In the present invention, it is preferable to connect a semi-inductive L-shaped balance having a rotating portion at the intersection of the vertical arm and the horizontal arm to the balance connecting portion 7. This is to prevent the gimmicks from getting entangled during casting and to prevent the airplane-shaped weight 1 for throwing fishing from rotating in conjunction with the rotation of the L-shaped balance. When using an L-shaped balance that does not have a rotating portion, a "twisting" (also referred to as "swivel" or "sarkhan") is interposed between the L-shaped balance and the balance connecting portion 7. May be good. As a result, even if the connected balance rotates during flight, the throw-fishing airplane-type weight 1 can maintain a stable flight attitude and improve the flight distance.
Even if the semi-inductive L-shaped balance does not have a rotating portion between the balance connecting portion 7 and the balance connecting portion 7, the flight distance is increased as compared with the conventional technique. Further, although it has been explained that the body portion 2 is formed into a predetermined shape by cutting a columnar member 8 made of synthetic resin, the above-mentioned shape is formed by using a well-known resin molding technique instead of the cutting technique. It can also be molded into.

胴体部２の左右側面には、胴体先端部２ａ近傍から胴体後端部２ｃ近傍にかけて左翼部３と右翼部４とが、中心軸線ＣＬを基準にして左右対称に取付けられている。左翼部３と右翼部４の取付け位置は、胴体部２の中心軸線ＣＬより上方であり、左翼部３と右翼部４は、胴体部２に水平、または、上反角を設けて取付けられてもよいし、翼端部のみを上方に反らせるように形成してもよい。左翼部３および右翼部４の平面形状は、翼根から翼端に向けて曲線を描いて先細りになるように形成され、一般的な航空機の三角翼（デルタ翼）の前縁、および、後縁を変形改良し、同一方向に湾曲させた形状をなしている。前縁後退角は、後縁後退角よりも大きくなるように形成されている。つまり、無尾翼機の形式であり、水平尾翼は設けられていない。また、本実施形態の左翼部３および右翼部４は、加工性を向上させるために、前縁から後縁までの翼厚が均一である合成樹脂製の平板を加工して形成されている。つまり、キャンバーが「０」の翼型（翼の断面形状）をなす対称翼である。左翼部３および右翼部４は、投げ釣り用飛行機型錘１の重心位置を考慮して、それぞれの翼根が、左翼部取付け位置調節溝３ａ、右翼部取付け位置調節溝４ａの適切な位置に埋設されて接着剤等で固定される。左翼部３および右翼部４を胴体部２に装着することで、キャスティング時の投げ釣り用飛行機型錘１の飛行中に十分な揚力を得ることができ、飛距離を向上することができる。
なお、加工が複雑にはなるが、一般的な飛行機の翼に見られるように、前縁が丸く、後縁が尖形であり、翼型に膨らみを持たせ、翼弦線の前縁から約１／３程度の位置に最大キャンバーを有するように加工された翼を設けてもよい。 On the left and right side surfaces of the fuselage portion 2, the left wing portion 3 and the right wing portion 4 are attached symmetrically with respect to the central axis CL from the vicinity of the fuselage tip portion 2a to the vicinity of the fuselage rear end portion 2c. The left wing portion 3 and the right wing portion 4 are attached above the central axis CL of the fuselage portion 2, and the left wing portion 3 and the right wing portion 4 are attached to the fuselage portion 2 with a horizontal or dihedral angle. Alternatively, it may be formed so that only the tip of the wing is warped upward. The planar shapes of the left wing 3 and the right wing 4 are formed so as to be curved and tapered from the wing root to the wing tip, and are formed at the leading edge and the trailing edge of a general aircraft delta wing. The edge is deformed and improved to form a curved shape in the same direction. The leading edge sweep angle is formed to have a size Kunar so than the trailing edge sweep angle. In other words, it is a tailless aircraft type, and no horizontal stabilizer is provided. Further, the left wing portion 3 and the right wing portion 4 of the present embodiment are formed by processing a flat plate made of synthetic resin having a uniform wing thickness from the leading edge to the trailing edge in order to improve workability. That is, it is a symmetrical wing having a camber of "0" (cross-sectional shape of the wing). In consideration of the position of the center of gravity of the airplane-shaped weight 1 for throwing fishing, the left wing portion 3 and the right wing portion 4 have their respective wing roots at appropriate positions of the left wing portion mounting position adjusting groove 3a and the right wing portion mounting position adjusting groove 4a. It is buried and fixed with an adhesive or the like. By attaching the left wing portion 3 and the right wing portion 4 to the fuselage portion 2, sufficient lift can be obtained during the flight of the airplane-type weight 1 for throwing fishing during casting, and the flight distance can be improved.
Although the processing is complicated, as seen in the wing of a general airplane, the leading edge is round, the trailing edge is pointed, the airfoil has a bulge, and from the leading edge of the chord line. A wing processed so as to have a maximum camber may be provided at a position of about 1/3.

胴体部２の中心軸線ＣＬ上の上面には、胴体先端部２ａ近傍から胴体後端部２ｃ近傍にかけて、垂直翼部５が取付けられている。垂直翼部５の側面形状は、前述した左翼部３および右翼部４の平面形状と同様に、翼根から翼端に向けて曲線を描いて先細りになるように形成されており、一般的な航空機の三角翼（デルタ翼）の前縁、および、後縁を同一方向に湾曲させた形状をなしている。また、垂直翼部５は、加工性を向上させるために、前縁から後縁までの翼厚が均一である合成樹脂製の平板を加工して形成され、大きさ（翼面積）は、左翼部３および右翼部４よりも小さく形成されている。また、垂直翼部５は、投げ釣り用飛行機型錘１の重心位置を考慮して、翼根が、垂直翼部取付け位置調節溝５ａの適切な位置に埋設されて固定される。垂直翼部５の前縁は、左翼部３および右翼部４の前縁よりも後方に位置するように取付けられている。垂直翼部５を胴体部２に装着することで、投げ釣り用飛行機型錘１の飛行中の直進性を向上することができる。 A vertical wing portion 5 is attached to the upper surface of the fuselage portion 2 on the central axis CL from the vicinity of the fuselage tip portion 2a to the vicinity of the fuselage rear end portion 2c. The side surface shape of the vertical wing portion 5 is formed so as to be tapered from the wing root to the wing tip in the same manner as the plan shape of the left wing portion 3 and the right wing portion 4 described above. The leading edge and trailing edge of the aircraft's triangular wing (delta wing) are curved in the same direction. Further, the vertical blade portion 5 is formed by processing a flat plate made of synthetic resin having a uniform blade thickness from the leading edge to the trailing edge in order to improve workability, and the size (blade area) is the left wing. It is formed smaller than the portion 3 and the right wing portion 4. Further, in the vertical wing portion 5, the wing root is embedded and fixed at an appropriate position in the vertical wing portion mounting position adjusting groove 5a in consideration of the position of the center of gravity of the airplane-shaped weight 1 for throwing fishing. The leading edge of the vertical wing portion 5 is attached so as to be located behind the leading edge of the left wing portion 3 and the right wing portion 4. By attaching the vertical wing portion 5 to the fuselage portion 2, it is possible to improve the straightness of the airplane-type weight 1 for throwing fishing during flight.

なお、左翼部取付け位置調節溝３ａ、右翼部取付け位置調節溝４ａ、垂直翼部取付け位置調節溝５ａの、左翼部３、右翼部４、垂直翼部５が取付けられた後の余剰部分には、合成樹脂を充填して溝を埋めてもよい。 In addition, in the surplus portion of the left wing portion mounting position adjusting groove 3a, the right wing portion mounting position adjusting groove 4a, and the vertical wing portion mounting position adjusting groove 5a after the left wing portion 3, the right wing portion 4, and the vertical wing portion 5 are mounted. , Synthetic resin may be filled to fill the groove.

図８に錘部６の説明図を示す。図８（ａ）は、錘部６の正面図、図８（ｂ）は、錘部６の右側面図である。錘部６は、中心部よりも前方が錘部６の重心になるように、側面形状が略半円形の鉛板を、前部に最大径が形成されるように変形された形状をなして形成されている。キャスティング時の飛行中の空気抵抗を小さくするように、錘部６の左側面６ｃおよび右側面６ｄは平坦に加工されており、錘部６の周縁部の内、少なくとも上側を除く周縁部は、丸みを付けて加工されている。錘部６の上側周縁部は、錘部取付け溝６ａに取付け可能な錘取付け部６ｂとして形成されている。 FIG. 8 shows an explanatory view of the weight portion 6. 8 (a) is a front view of the weight portion 6, and FIG. 8 (b) is a right side view of the weight portion 6. The weight portion 6 has a lead plate having a substantially semicircular side surface shape so that the center of gravity of the weight portion 6 is in front of the center portion, and is deformed so that the maximum diameter is formed in the front portion. It is formed. The left side surface 6c and the right side surface 6d of the weight portion 6 are processed to be flat so as to reduce the air resistance during flight during casting, and the peripheral portion of the peripheral portion of the weight portion 6 except for the upper side is formed. It is rounded and processed. The upper peripheral edge portion of the weight portion 6 is formed as a weight mounting portion 6b that can be mounted in the weight portion mounting groove 6a.

本実施形態の投げ釣り用飛行機型錘１は、胴体部２の下面前方に錘部６を装着することで、重心Ｇ１が、胴体部２の長手方向の中心Ｃ２（つまり、胴体部２の全長ＦＬの半分ＨＦＬの位置。）よりも前方で、かつ、中心軸線ＣＬよりも下方に位置している（図７（ａ）参照。）。このため、図９に示すように、投げ釣り用飛行機型錘１を鉛直方向に吊り下げた状態では、中心軸線ＣＬが鉛直線ＶＬに対して錘部６と逆側に角度αを有する姿勢で静止する。図７（ａ）について言えば、錘部６の重さが重いほど、重心Ｇ１は、胴体部２の前方、かつ、下方に移動し、図９において、角度αが大きくなる。なお、図９では、天秤連結部７に、紐（Ｌ字型天秤でも可）を結びつけて、投げ釣り用飛行機型錘１を鉛直方向に吊り下げているが、紐の部分は図示していない。
このように重心Ｇ１の位置を、胴体部２の長手方向の中心Ｃ２よりも前方で、かつ、中心軸線ＣＬよりも下方に設定することで、左翼部３および右翼部４に発生する揚力と重力とのバランスが最適化され、失速せずに、直線的に滑空する期間を延ばし（つまり、飛行軌跡の直線部分を延ばし）、飛距離を大幅に向上することができる。 In the airplane-type weight 1 for throwing fishing of the present embodiment, by mounting the weight portion 6 in front of the lower surface of the body portion 2, the center of gravity G1 becomes the center C2 in the longitudinal direction of the body portion 2 (that is, the total length of the body portion 2). It is located in front of the half HFL position of FL) and below the central axis CL (see FIG. 7A). Therefore, as shown in FIG. 9, when the throwing fishing airplane type weight 1 is suspended in the vertical direction, the central axis CL has an angle α on the opposite side of the weight portion 6 with respect to the vertical line VL. Stand still. Regarding FIG. 7A, the heavier the weight of the weight portion 6, the more the center of gravity G1 moves forward and downward of the body portion 2, and the angle α becomes larger in FIG. In FIG. 9, a string (an L-shaped balance is also possible) is tied to the balance connecting portion 7, and the airplane-shaped weight 1 for throwing fishing is suspended in the vertical direction, but the string portion is not shown. ..
By setting the position of the center of gravity G1 in front of the center C2 in the longitudinal direction of the body portion 2 and below the center axis CL in this way, the lift and gravity generated in the left wing portion 3 and the right wing portion 4 are set. The balance with and is optimized, and the period of linear gliding can be extended (that is, the straight part of the flight trajectory is extended) without stalling, and the flight distance can be greatly improved.

The total length FL of the body portion 2 is 130 mm, and the outer diameter of the maximum diameter portion 2a is 18.5 mm. The left wing portion 3 and the right wing portion 4 each have a wing thickness of 0.8 mm, a wing root chord length of 95 m, and a wingspan excluding the fuselage portion 2 of 140 mm. The vertical blade portion 5 has a blade thickness of 0.8 mm, a wing root chord length of 90 mm, and a blade height of 45 mm. The left wing mounting position adjusting groove 3a, the right wing mounting position adjusting groove 4a, and the vertical wing mounting position adjusting groove 5a have a groove length of 120 mm, respectively. Each is formed so as to be able to independently adjust the attachment position to the body portion 2 in the front-rear direction. The tips of the left wing mounting position adjusting groove 3a, the right wing mounting position adjusting groove 4a, and the vertical wing mounting position adjusting groove 5a are formed at positions 10 mm from the fuselage tip 2a, and the tips of the left wing 3 and the right wing 4 are formed. The portion is formed at a position 25 mm from the fuselage tip portion 2a, and the tip portion of the vertical wing portion 5 is formed at a position 30 mm from the fuselage tip portion 2a. The length of the weight mounting portion 6b, which is the upper peripheral edge of the weight portion 6, is 55 mm, and a weight mounting groove 6a having a length that allows the weight mounting portion 6b to be mounted is formed on the lower surface of the body portion 2.

The weight of the weight portion 6 can be varied by varying the thickness of the lead plate forming the weight portion 6. Then, by adjusting the attachment positions of the left wing portion 3 and the right wing portion 4 to the fuselage portion 2 according to the weight of the weight portion 6, the flight distance is maintained in response to the fluctuation of the weight of the weight portion 6. Can be done. For example, when the weight of the weight portion 6 is increased, the left wing portion 3 and the right wing portion 4 are adjusted and attached so as to be closer to the fuselage tip portion 2a, and when the weight of the weight portion 6 is reduced, the left wing portion 3 and the right wing portion 4 are attached. The right wing portion 4 may be adjusted and attached in a direction away from the fuselage tip portion 2a.

本実施形態の投げ釣り用飛行機型錘１のキャスティング時の飛行状態について、説明する。従来の一般的な錘を用いたキャスティングでは、錘を一定の仰角を付けて投げる必要があり、錘は山なりの飛行軌跡を描いて飛行し、飛行ロスが大きく飛距離がでなかった。また、上記特許文献２の技術では、飛距離は１００ｍ〜１３０ｍである。図１０は、竿３０に、半誘導式のＬ字型天秤（不図示）を介して道糸６０が連結された投げ釣り用飛行機型錘１を、陸地４０から、海５０に向かってキャスティングしたときの、投げ釣り用飛行機型錘１の飛行状態を示している。符号Ｄは、直線的な飛行軌跡を示している。図１０に示すように、投げだし時の角度は、ほぼ水平であり、飛行姿勢が水平状態で直線的に滑空して、飛距離１５０ｍ以上を実現することができた。従来技術に比べ、同じ力で飛距離を延ばすことができるので、従来技術と同じ飛距離であれば、少ない力で投げることができ、ユーザーの体力消耗を軽減することができる。また、釣り場において周囲の釣り人よりも遠くへ仕掛けを飛ばすことで、釣果の向上が期待できる。 The flight state at the time of casting of the airplane-type weight 1 for throwing fishing of the present embodiment will be described. In conventional casting using a general weight, it is necessary to throw the weight with a constant elevation angle, and the weight flies in a mountainous flight trajectory, resulting in a large flight loss and a short flight distance. Further, in the technique of Patent Document 2, the flight distance is 100 m to 130 m. In FIG. 10, a throw fishing airplane-shaped weight 1 in which a road thread 60 is connected to a rod 30 via a semi-inductive L-shaped balance (not shown) is cast from land 40 toward the sea 50. The flight state of the airplane-type weight 1 for throwing fishing at that time is shown. Reference numeral D indicates a linear flight trajectory. As shown in FIG. 10, the angle at the time of throwing was almost horizontal, and the flight attitude was horizontal and gliding linearly, and a flight distance of 150 m or more could be realized. Since the flight distance can be extended with the same force as compared with the conventional technique, if the flight distance is the same as that of the conventional technique, the ball can be thrown with less force, and the user's physical exhaustion can be reduced. In addition, it can be expected that the fishing results will be improved by flying the gimmicks farther than the surrounding anglers at the fishing spot.

なお、本願出願人は、全長が１２０ｍｍ〜１５０ｍｍの胴体部２について、適宜、錘部６の重量と、左翼部３および右翼部４の取付け位置とを調節して、投げ釣り用飛行機型錘１を構成し、実際にキャスティングを行い、飛距離１５０ｍ以上を確認した。 The applicant of the present application adjusts the weight of the weight portion 6 and the mounting positions of the left wing portion 3 and the right wing portion 4 appropriately for the fuselage portion 2 having a total length of 120 mm to 150 mm, and the airplane-type weight 1 for throwing fishing. Was constructed, and casting was actually performed, and a flight distance of 150 m or more was confirmed.

本実施形態の投げ釣り用飛行機型錘１によれば、重心Ｇ１が、胴体部２の全長ＦＬの半分ＨＦＬの位置よりも胴体先端部２ａ側に設けられているので、サーフトロールのリトリーブ時に、リールで引く際には、胴体後端部２ｃが水面から浮き上がった状態になり、また、胴体部２の後部が流線型に形成されているので、空気抵抗が小さくなり、かつ、水面を跳ねるときの水圧も小さくなるので、リールを操作する力が少なくてすむ。また、投げ釣り用飛行機型錘１が、水面を跳ねることで、魚の注意を引き、食いつきがよくなり、釣果の向上が期待できる。 According to the airplane-type weight 1 for throwing fishing of the present embodiment, the center of gravity G1 is provided on the fuselage tip 2a side of the position of half HFL of the total length FL of the fuselage 2, so that the surf roll can be retrieved at the time of retrieval. When pulling with a reel, the rear end 2c of the fuselage is in a state of being lifted from the water surface, and since the rear portion of the fuselage 2 is formed in a streamlined shape, the air resistance is reduced and the water surface is bounced. Since the water pressure is also reduced, less force is required to operate the reel. In addition, the airplane-shaped weight 1 for throwing fishing attracts the attention of the fish by bouncing on the surface of the water, and the bite is improved, which can be expected to improve the fishing result.
