【０００３】
【特許文献１】には、一方の挟部が鋭角の挟部となり他方の挟部が平面の挟部となった釣り用錘の鉛玉に使用するヤットコが示されている。
【０００４】
特許文献１のように一方の挟部が鋭角の挟部となった釣り用錘の開き具は、錘の切り欠きに鋭角の挟部が差し込まれて容易に錘の切り欠きを開くことが出来るが、この特許文献１のように鋭角の挟部が長手方向に延びていると、鋭角の挟部が切り欠きに差し込まれるにつれて球状の錘が転がるように移動してしまうため、切り欠きが一様に開かず、切り欠きの一側が広く他側が狭く開いた状態になることがあった。
したがって、この様な状態に開いた釣り用錘を釣り糸に取り付けようとしてもしっかりと釣り糸を挟持できないことがあった。
【０００５】
【発明が解決しようとする課題】
解決しようとする課題は、
球状の錘の切り欠き（切り込み部）が一様に開かず、切り欠きの一側が広く他側が狭く開いた状態になることである。
【０００６】
本発明の目的は前記欠点に鑑み、錘の切り欠き（切り込み部）を開くときに、錘が移動せず、切り欠きを一様に開くことができる釣り用錘の開き具を提供することである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、
請求項１に係わる本発明は、一対の挟持片で釣り用錘を挟んで前記釣り用錘の切り込み部を開く釣り用錘の開き具において、前記一対の挟持片の一方に、前記挟持片の長手方向に延びる割り刃を設けると共に、前記割り刃の長手方向の端部に受け部を設けたこと要旨とするものである。
【０００８】
【発明の実施の形態】
以下、図示の実施例によって本発明を説明すると、本発明は、図１から図５で、図１は釣り用錘の開き具の側面図、図２は挟持片の拡大断面図、図３は使用状態の挟持片の部分斜視図、図４は釣り用錘を開いた状態の挟持片の拡大断面図、図５は錘を開いた状態の挟持片の部分拡大側面図である。
【０００９】
図１において、本発明の釣り用錘の開き具１は、一対の挟持桿２，３をそれぞれの中間で交差し、この交差部分を軸４で回動自在に軸支している。
軸４の先端側が一対の挟持片２ｂ、３ｂとなり、軸４の手元側に一対のハンドル状の操作部２ａ、３ａが形成され、操作部２ａ、３ａを互いに離れる方向に操作（回動）すると挟持片２ｂ、３ｂが互いに離れて開いた状態となり、操作部２ａ、３ａを互いに接近させる方向に操作（回動）すると挟持片２ｂ、３ｂが互いに接近し閉じた状態となる。
【００１０】
挟持桿２，３および軸４は、ステンレス、チタン合金等の金属で形成され、一般の錘Ｗを形成する金属の鉛より大きい硬度を有している。
操作部２ａ、３ａには、握りやすいように柔軟性を有する合成樹脂のカバーが取り付けられている。
【００１１】
一対の挟持片２ｂ、３ｂは、軸４に近い元部側に両挟持片２ｂ、３ｂの刃が噛み合う切断部７を有し、挟持片２ｂ、３ｂの開放端である先端側において、一方の挟持片３ｂの挟持部３ｃ側に割り刃５を形成し、対面する他方の挟持片２ｂの挟持部２ｃと共に釣り用錘を挟圧して切り込み部を開くようになっている。
【００１２】
さらに図２、３のように挟持桿２、３の一方の挟持片３ｂには、その挟持部３ｂに挟持片３ｂの先端から元部側（軸４側）に向かう長手方向に割り刃５が形成されている。
この割り刃５は尖端が錘の切り込み部に入る程度にとがった峰部５ａが挟持片３ｂの長手方向に延びており、その左右両側が徐々に挟持片３ｂの背面３ｅに向けて幅広になるように傾斜する傾斜面５ｂ、５ｃが形成されて、側面３ｄに至る。
割り刃５は、挟持片３ｂの先端から元部側に延設され、受け部６ａに突き当り、これより元部側の挟持部３ｃは多数の挟持片３ｂの長手方向を横切る方向に延びる凹凸が形成された挟持面３ｆが形成されている。
挟持面３ｆは、峰部５ａと同様の高さを有し、その部分の側面３ｄは、峰部５ａが形成された部分の側面３ｄより幅広に形成されている。
【００１３】
受け部６ａは、割り刃５の元部側の端部に設けられ、その傾斜面５ｂ、５ｃの端部から挟持片３ｂの長手方向に交差する方向の面で形成され、挟持部３ｃ及び側面３ｄに達するように形成されている。
本実施形態では、挟持片３ｂの長手方向に直行する平面で形成されているが、受け部６ａはこれに限らず、錘Ｗの切り込み部を割り刃５で開くときに、錘Ｗの外側が当接するもので、錘Ｗの移動を止める移動阻止体が形成されていればよい。
したがって、挟持面３ｆのように挟持片３ｂ先端に向けて平面状に形成されているのに比べてこれより先端側に向かうように傾斜した面で形成でき、さらに、面でなく、凹凸でもよい。
【００１４】
一方、他方の挟持片２ｂは、挟持片３ｂに向かう対向面から成る挟持部２ｃを有し、この挟持部２ｃは、多数の挟持片２ｂの長手方向を横切る方向に延びる凹凸が形成された挟持面２ｆが形成されている。
この凹凸が形成された挟持面２ｆは、挟持片３ｂの割り刃５および多数の凹凸が形成された挟持面２ｆに対向する範囲に合致して設けられている。
【００１５】
この様に形成した釣り用錘の開き具を使用するときは、図１の二点鎖線で示したように、操作部２ａ、３ａを開いて錘Ｗが挟持できるように挟持片２ｂ、３ｂを開く。
次に、図３のように、挟持片２ｂの挟持部２ｃに錘Ｗを切り込み部Ｗ１を対向する挟持片３ｂの割り刃５の長手方向に合わせて配置する。
この時、割り刃５が挟持片３ｂの長手方向に延びて形成されているため錘Ｗの位置合わせがし易く、切り込み部を開いたときに錘Ｗが広がる方向を、この広がりに対向して指で押さえ易いため、開き操作中に錘Ｗを落としにくい。
そして、錘Ｗが落ちないように手で押さえながら図４、図５のように、操作部２ａ、３ａを閉じて挟持部２ｃ、３ｃを閉じて錘Ｗを挟持する。
【００１６】
この時、挟持片３ｂの割り刃５が錘Ｗの切り込み部Ｗ１に差し込まれ、峰部５ａが侵入した後両側の傾斜面５ｂ、５ｃが切り込み部Ｗ１の内側に当接しながら侵入してこれを開き、一方、挟持片２ｂの、前記挟持片３ｂ側の割り刃５の対向位置には、多数の凹凸が形成された挟持面２ｆが形成されているので錘Ｗが挟持片２ｂ、３ｂで挟持されると挟持面２ｆの多数の凹凸が錘Ｗの外側に食い込むため、錘Ｗの移動を防止する。
さらに、挟持片３ｂの割り刃５の元部側端部に形成した受け部６ａが球状の錘が転がるように移動したときでも、その外側に当接し、移動を阻止する。
とくに挟持片２ｂ、３ｂが軸４を中心に回動して錘Ｗを挟持する場合、錘Ｗは割り刃５が元部側から当たり始めて錘Ｗを押さえ込み、錘Ｗは元部側へ転がるように逃げるため、受け部６は、回動軸４側の元部側に設けるとその移動を阻止して切り込み部Ｗ１の開き方をその一側と他側で異ならないように一様にすることができる。
【００１７】
本発明の釣り用錘の開き具は、この実施形態に限定されず、例えば割り刃５は挟持片の先端に設けず、中間位置に設けて、その先端側と元部側に挟持面を形成しても良い。
さらに、受け部は、割り刃の元部側に設けたが、先端側に設けてもよく、割り刃の長手方向の少なくとも一方の端部に設ければよい。
【００１８】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a fishing weight opening tool that opens a cut portion of the fishing weight by sandwiching the fishing weight with a pair of holding pieces.
[0002]
[Prior art]
[Patent Document 1] Japanese Utility Model Publication No. Sho 59-143653
Patent Literature 1 discloses a yatco used for a lead ball of a fishing weight in which one of the sandwiched portions is an acute-angled sandwiched portion and the other is a flattened sandwiched portion.
[0004]
As disclosed in Patent Literature 1, an opening part of a fishing weight in which one of the sandwiching portions is an acute-angled sandwiching portion can easily open the notch of the weight by inserting the sharp-angled sandwiching portion into the notch of the weight. However, if the acute-angled holding portion extends in the longitudinal direction as in Patent Literature 1, the spherical weight moves so as to roll as the acute-angled holding portion is inserted into the notch. In some cases, the notch did not open and one side of the notch was wide and the other side was narrow.
Therefore, even when the fishing weight opened in such a state is to be attached to the fishing line, the fishing line may not be firmly held.
[0005]
[Problems to be solved by the invention]
The problem to be solved is
The notch (cut portion) of the spherical weight does not open uniformly, and one side of the notch is wide and the other side is narrow and open.
[0006]
SUMMARY OF THE INVENTION In view of the above-described drawbacks, an object of the present invention is to provide a fishing weight opening tool that can open a notch uniformly without opening the notch (cut portion) of the weight. is there.
[0007]
[Means for Solving the Problems]
In order to solve the above problems,
The present invention according to claim 1 is a fishing weight opening tool that opens a cut portion of the fishing weight by sandwiching the fishing weight with the pair of holding pieces, wherein one of the pair of holding pieces has one of the holding pieces. The gist of the present invention is that a split blade extending in the longitudinal direction is provided, and a receiving portion is provided at an end of the split blade in the longitudinal direction.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described below with reference to the illustrated embodiment. The present invention is shown in FIGS. 1 to 5, wherein FIG. 1 is a side view of an opening of a fishing weight, FIG. 2 is an enlarged sectional view of a holding piece, and FIG. FIG. 4 is an enlarged sectional view of the holding piece with the fishing weight opened, and FIG. 5 is a partially enlarged side view of the holding piece with the weight opened.
[0009]
In FIG. 1, an opening 1 of a fishing weight according to the present invention intersects a pair of holding rods 2 and 3 in the middle of each other, and rotatably supports the intersection with a shaft 4.
When the distal end side of the shaft 4 becomes a pair of holding pieces 2b, 3b, a pair of handle-like operating portions 2a, 3a are formed on the hand side of the shaft 4, and when the operating portions 2a, 3a are operated (rotated) in a direction away from each other. The holding pieces 2b, 3b are separated from each other and open, and when the operating portions 2a, 3a are operated (rotated) in a direction to approach each other, the holding pieces 2b, 3b come close to each other and become closed.
[0010]
The holding rods 2 and 3 and the shaft 4 are formed of a metal such as stainless steel or a titanium alloy, and have a hardness higher than that of the lead that forms the general weight W.
A flexible synthetic resin cover is attached to the operation units 2a and 3a so as to be easy to grasp.
[0011]
The pair of holding pieces 2b, 3b have a cutting portion 7 on the base side near the shaft 4 where the blades of the two holding pieces 2b, 3b mesh with each other. A split blade 5 is formed on the holding portion 3c side of the holding piece 3b, and the cutting weight is opened by holding the fishing weight together with the holding portion 2c of the other holding piece 2b facing the cutting blade.
[0012]
Further, as shown in FIGS. 2 and 3, one of the holding pieces 3b of the holding rods 2, 3 is provided with a split blade 5 on the holding portion 3b in the longitudinal direction from the tip of the holding piece 3b toward the base portion (the shaft 4 side). Is formed.
The split blade 5 has a ridge 5a extending in the longitudinal direction of the holding piece 3b so that the tip enters the cut portion of the weight. The inclined surfaces 5b and 5c are formed as described above, and reach the side surface 3d.
The splitting blade 5 extends from the tip of the holding piece 3b to the base part and abuts against the receiving part 6a. The holding part 3c on the base part has unevenness extending in a direction crossing the longitudinal direction of the many holding pieces 3b. The formed holding surface 3f is formed.
The holding surface 3f has the same height as the peak 5a, and the side surface 3d of the portion is formed wider than the side 3d of the portion where the peak 5a is formed.
[0013]
The receiving portion 6a is provided at the end of the split blade 5 on the base portion side, and is formed by a surface extending in a direction intersecting the longitudinal direction of the holding piece 3b from the end of the inclined surface 5b, 5c. It is formed to reach 3d.
In the present embodiment, the holding portion 3a is formed by a plane perpendicular to the longitudinal direction of the holding piece 3b, but the receiving portion 6a is not limited to this. It suffices that a movement stopper that stops the movement of the weight W be formed.
Therefore, it can be formed as a surface inclined toward the front end side, as compared with a flat surface toward the front end of the holding piece 3b like the holding surface 3f. .
[0014]
On the other hand, the other holding piece 2b has a holding portion 2c composed of an opposing surface facing the holding piece 3b. The surface 2f is formed.
The holding surface 2f on which the unevenness is formed is provided in conformity with a range facing the split blade 5 of the holding piece 3b and the holding surface 2f on which a large number of unevennesses are formed.
[0015]
When using the fishing weight opening tool formed in this way, as shown by the two-dot chain line in FIG. 1, the holding parts 2b, 3b are opened so that the operating parts 2a, 3a can be opened and the weight W can be held. open.
Next, as shown in FIG. 3, the weight W is cut into the holding portion 2c of the holding piece 2b so that the cut portion W1 is arranged in the longitudinal direction of the split blade 5 of the opposing holding piece 3b.
At this time, since the split blade 5 is formed so as to extend in the longitudinal direction of the holding piece 3b, the weight W can be easily aligned, and the direction in which the weight W expands when the cut portion is opened is opposed to the expansion. Since it is easy to press with a finger, it is difficult to drop the weight W during the opening operation.
Then, while holding down the weight W by hand so that the weight W does not fall, as shown in FIGS. 4 and 5, the operation parts 2a and 3a are closed and the holding parts 2c and 3c are closed to hold the weight W.
[0016]
At this time, the splitting blade 5 of the holding piece 3b is inserted into the notch W1 of the weight W, and after the ridge 5a enters, the inclined surfaces 5b, 5c on both sides enter the notch W1 while coming into contact with the inside thereof. On the other hand, since a holding surface 2f having a large number of irregularities is formed at a position of the holding piece 2b facing the splitting blade 5 on the holding piece 3b side, the weight W is held by the holding pieces 2b and 3b. When this is done, a large number of irregularities on the holding surface 2f bite into the outside of the weight W, thereby preventing the weight W from moving.
Further, even when the receiving portion 6a formed at the base end of the splitting blade 5 of the holding piece 3b moves so that the spherical weight rolls, the receiving portion 6a comes into contact with the outside thereof to prevent the movement.
In particular, when the holding pieces 2b and 3b rotate around the shaft 4 and hold the weight W, the weight W starts to hit the split blade 5 from the base side, presses the weight W, and the weight W rolls toward the base side. When the receiving portion 6 is provided on the base portion side of the rotating shaft 4, the movement is prevented and the opening of the cut portion W1 is made uniform so that it does not differ from one side to the other side. Can be.
[0017]
The opening device of the fishing weight of the present invention is not limited to this embodiment. For example, the splitting blade 5 is not provided at the tip of the holding piece, but is provided at an intermediate position to form a holding surface on the tip side and the base portion side. You may.
Further, the receiving portion is provided on the base portion side of the split blade, but may be provided on the distal end side, or may be provided on at least one end in the longitudinal direction of the split blade.
[0018]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
[0019]
When the cut portion of the weight is opened, the weight does not move and the cut portion can be opened uniformly.
