Description

  The present invention relates to a fishing light weight.

A fishing weight is generally required to sink a device with bait on a fishhook into the sea, and its shape is eggplant type, Odawara type, Tyco type, rudder type, trunk type, medium weight Various types such as type and bichicago type are used.
These fishing weights are all made of lead.
The shape of the above-described conventional fishing weight is shown in FIG.

Moreover, it is feared that lead used in many fishing weights in recent years has an adverse effect on the human body and the environment, but most fishing weights are still made of lead.
In addition, a weight using a material (metal, alloy) which is not soluble in water instead of lead has been proposed (Patent Document 1).

In recent years, fishing weights incorporating light emitters have also been proposed.
This is a fishing weight in which a light emitting diode is incorporated as a light emitter inside a container made of synthetic resin and lead (Patent Document 2).

Further, as an improvement on the fishing weight, a light emitting body and a battery are incorporated in a weight made of a combination of synthetic resin and lead, and a light emitting device provided with a metal external terminal as a switch circuit on the outer surface of the weight. A fishing weight with a body has also been proposed (Patent Document 3).
This example also uses a light emitting diode as the light emitter. This example also shows an example in which a transistor circuit is used to light a light emitter.

The problems to be solved are as follows.
(1) The lead of fishing weights has an adverse effect on the human body and the environment.
(2) When the bait is submerged in the sea, even if the bait is recognized by a nearby fish, it cannot be seen by a fish that is some distance away, so the fishing results are limited.
(3) In addition, when the water is cloudy due to rough bottom, etc., it is considered that the fishing results are bad and it is difficult to find the bait.
(4) In addition, fishing weights can always be lost in the sea due to their roots, causing pollution of river water and seawater, as well as the human body that eats the fish. Is one of the themes for the future.

The most important feature of the present invention is that the light emitting weight for fishing is made of a stainless steel metal material and a synthetic resin, and the light emitting weight for fishing has a fish collecting effect while considering the environment.
In addition, by incorporating an electric light emitting function into the fishing light weight itself, using the fish collection effect in the sea, raising the fishing results, and using a material that does not release harmful substances even if lost The objective is achieved.

The fishing light weight of the present invention has the following effects.
(1) Since lead is not used in the weight, it does not adversely affect the human body or the environment.
(2) When the bait is submerged in the sea, it can be seen not only by nearby fish but also by fish that are some distance away, so the fish collection effect is improved and fishing results can be raised.
(3) Even when the water is cloudy due to rough bottoms, etc., it is easy to find bait, so the fishing results can be raised.
(4) It is difficult to root due to the shape of the weight. Moreover, even if it is rooted, it is made of a material that does not dissolve harmful substances, so it is possible to prevent pollution of river water and seawater.
