Description

[0001]
[Industrial application fields]
The present invention relates to a fishing weight and a fishing net weight.
[0002]
[Prior art]
The shape of the conventional weight is various, but the body part is a hard piece of lead or the like, and if it gets into a V-shaped gap between rocks and rocks, it takes root with a very high probability, The weights themselves, fishing hooks, gimmicks were lost, or the nets were damaged frequently. It is also very uneconomical, and the weights, fishhooks, gimmicks, or nets left behind on the seabed have a negative impact on the environment.
[0003]
It is also conceived that the surface of the weight is covered with vinyl, etc., and the surface is made slippery to prevent rooting. However, if the weight is cut into the gap between the V-shaped sharp rock and the rock, Since the whole weight is hard, the probability of detachment is low, and it does not lead to a surprising improvement in the rooting rate.
[0004]
It is also considered that the fishing tackle itself is devised to prevent rooting, but it is a fishing device that is devised to avoid rooting by attaching various accessories to the weight, increasing the volume and specific gravity However, there is a disadvantage that the basic performance as an original fishing weight, for example, the stability at the bottom of the water is lost.
[0005]
[Problems to be solved by the invention]
The present invention has a fishing weight and a fishing net weight that have the basic performance as a weight, such as specific gravity, volume, surface area, etc., and that make it easier to escape from the rooted weight. Is intended to provide.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a cross-sectional view for explaining an example of an embodiment of a fishing weight of the present invention. In the figure, 1 is a main body container, 2 is a conical cap, 3 is a twist-back fitting, 4 is a thread loop, 5 is a lubricant, 6 is a fishing line, and 7 is a spherical weight.
[0011]
A plurality of spherical weights 7 made of lead or iron metal are arranged in a row without being connected, and the whole is covered with the main body container 1. The main body container 1 is formed of a stretchable material such as synthetic rubber. Inside the main body container 1, friction between the spherical weight 7 and the synthetic rubber main body container 1, between the adjacent spherical weights 7. Lubricant 5 is injected to reduce friction at the contacts.
[0012]
The fishing weight is ideally all in one piece, but from the viewpoint of manufacturing cost, as an embodiment, it is divided into a sharp conical cap 2 and a main body container 1 at the tip portion. After injecting the lubricant 5, the spherical weights 7 are packed in order.
[0013]
In the conical cap 2 made of synthetic rubber at the tip, a strong thread ring 4 for passing the thread is arranged on a untwisted metal fitting 3 which is one factor of the root, and the conical cap 2 Finally, it is completed by bonding to the main body container 1 in which the spherical weight 4 is built.
[0014]
Further, the main body container 1 is preferably made of synthetic rubber having adhesion and stretchability so that a dent can be formed between adjacent spherical weights 7. This is to suppress fluidity due to water flow at the bottom of the water.
[0015]
The difference between the fishing weight of the present invention and the conventional fishing weight is also a difference in the viewpoint of the root cause. Originally, it is rare that the weight itself is sandwiched between rocks and rocks from the beginning and causes rooting, but it is pulled between the rocks and rocks by being pulled by the thread, and causes rooting. That is, the fishing line makes the root cause before the newt. Therefore, the transition portion from the fishing line to the weight, that is, the tip portion of the weight is a very important portion in the root. It is a requirement that the tip portion of the weight is desired to be sharper, and naturally, the tip portion is hard or soft, so that the softer one can cope with more complicated changes, In the fishing weight of the present invention, since the expansion and contraction force of the synthetic rubber is used, it is a sharp conical shape made of synthetic rubber.
[0016]
The fishing weight of the present invention is not simply a synthetic rubber main body container that covers a plurality of subdivided spherical weights, but a lubricant to reduce frictional resistance in the main body container. That was injected. Then, create a state in which the spherical weight can be moved and rotated in the main body container, and when it is rooted, the synthetic rubber at the contact point of the root is gradually moved, and the frictional force of the contact point is increased By breaking the balance with the shrinkage force of rubber, the structure allows escape from the root.
[0017]
As described above, the present invention has been invented from the viewpoint of how the rooted weight can be escaped. Judging from the fact that most of the root cause is caused by the entry of the weight into the V-shaped sharp gap formed between the rocks and the horizontal V-shaped sharp gap formed between the water bottom and the rock. Invented the structure to escape from it. In addition, the basic idea is that the weight can be used with the specific gravity of the weight almost unchanged from that of the conventional one, and the method of use can be kept the same as the conventional one. And, compared to the conventional one piece of hard lead or iron weight, spherical weights made of metal with smaller diameters are arranged in a line in stages, covered with synthetic rubber so that they are all in close contact, and stretched as a whole It is made by adding a lubricant inside.
[0018]
The reason why the lubricant is injected inside is to suppress the friction between the spherical weight and the synthetic rubber, and the spherical weight and the spherical weight, and thereby the expansion and contraction of the synthetic rubber and the spherical weight inside the main body container. It is possible to move and rotate, reduce the frictional force at the contact point between the rock and the weight of the root, and break the balance between the frictional force and the contraction force of the synthetic rubber.
[0019]
For example, when a part of a weight is sandwiched between the V-shaped gaps, as shown in FIG. 2, first, the contact point between the rock and the sandwiched weight is a synthetic rubber spherical surface. After that, when pulled by the fishing line, the front part is extended from the pinched spherical weight, and the pinched weight moves backward from the first contact point while rotating inside the main body container, and from the contact point to the rear part Will gradually accumulate the shrinkage of the synthetic rubber. At the same time that the synthetic rubber of the whole weight is stretched, the synthetic rubber at the contact point between the synthetic rubber and the rock is also stretched and thinned, and the contact point moves further. Then, the balance between the contracting force of the synthetic rubber stored in the rear portion and the frictional force between the root contact and the root contact is lost, and it is possible to escape upward.
[0020]
FIG. 3 is a cross-sectional view for explaining an example of the embodiment of the fishing net weight of the present invention. In the figure, the same parts as those in FIG. The essential structure of the fishing net weight is the same as the fishing weight, in which a plurality of metal spherical weights are arranged in a row without being connected, and the whole is closely attached by a main body container formed of a stretchable material. As shown in FIG. 3, the weights arranged in a row are the spherical weights with the maximum diameter at the center. It is preferable that the diameters are arranged so as to decrease stepwise from both ends.
[0021]
【The invention's effect】
According to the present invention, it is possible to provide a fishing weight and a fishing net weight that are very economical and environmentally friendly by removing the root and greatly improving the recovery rate of the weight. In addition, compared to conventional weights, it is the same weight when throwing, but when drawing from the water, synthetic rubber, etc. gets wet with water, creating surface lubricity, reducing resistance with the bottom of the water, and more There is an effect that it can be pulled easily and the load on the yarn can be reduced.
