Description

[Technical Field]

[0001] The present invention relates to a fishing sinker. [Background technology]

[0002] An idea for a fishing sinker. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2012-152201 [Patent Document 2] Patent 7361964 [Patent Document 3] Patent Publication No. 2020-188730 Summary of the Invention [Problem to be solved by the invention]

[0004] To provide a sinker that is less susceptible to trouble caused by snagging on rocks or stones on the seabed. [Means for solving the problem]

[0005] A metal ring is attached to the top to which the power line and the tackle line can be connected, and the inside is hollow to provide buoyancy. The upper part of the weight is made of resin and has a daruma-shaped buoyancy function, with a disk-shaped neodymium magnet attached, and the upper part has a metal disk-shaped magnetic body. The attached plastic lid was placed in a metal container filled with lead up to the middle of the container, and a washer was attached to prevent tipping over. The lower part of the weight is attracted by the magnetic force of a disc-shaped neodymium magnet. Also, the cross section of the outer periphery of the disk-shaped neodymium magnet attached to the bottom of the sinker is used as a bait. If the sinker gets caught on rocks or stones on the seabed, the upper part of the sinker will move in the direction of the incline via the ring. In order to increase the effect of the lever when the line is pulled, the metal structure is semicircular and has a short distance between the fulcrum and the point of action. The disk-shaped magnetic body can be separated even with a small force when the lower part of the weight to which it is attached is separated. [Effects of the Invention]

[0006] There are fewer problems caused by snags on rocks and stones on the seabed. [Brief explanation of the drawings]

Claims

1. A metal ring is attached to the top to which the power line and the tackle line can be connected, and the inside is hollow to provide buoyancy. The upper part of the weight is made of resin and has a daruma-shaped buoyancy function, with a disk-shaped neodymium magnet attached, and the upper part has a metal disk-shaped magnetic body. The attached plastic lid was placed in a metal container filled with lead up to the middle of the container, and a washer was attached to prevent tipping over. This fishing sinker is characterized by a mechanism in which the lower part of the sinker is attracted by the magnetic force of a disk-shaped neodymium magnet.

2. The mechanism of claim 1 is used to detect bites on the outer periphery of a disk-shaped neodymium magnet attached to the bottom of the upper part of the sinker. If the sinker gets caught on rocks or stones on the seabed, the upper part of the sinker will move in the direction of the incline via the ring. In order to increase the effect of the lever when the line is pulled, the metal structure is semicircular and has a short distance between the fulcrum and the point of action. To provide a fishing sinker which can separate a lower part of the sinker to which a disk-shaped magnetic body is attached even when the force required to separate the lower part is small.
