Abstract

PROBLEM TO BE SOLVED: To provide a fishing sinker enabling the many movements, easy attachments/detachments of a fishing line without damaging a fishing line. SOLUTION: This fishing sinker is composed of a sinker main body 1 having a spherical outer shape and a nipping member 2 having a sliced boiled fish paste (Kamaboko) shape. The sinker main body 1 is produced from a metal having a specific gravity of >=7 such as tungsten, a tungsten alloy, an iron-based metal such as stainless steel, or a copper alloy. An elastomer for forming the nipping member 2 is formed from an easily deformable material having lower hardness than that of the sinker main body 1, and a polymer material such as a rubber, a synthetic rubber or a synthetic resin is used as the easily deformable material. A slitting groove 1a is formed in the sinker main body 1 in a spherical shape, and the slitting groove 1a is formed in a flask cross section shape having vertical planes (a) and a circular shape (b), and the circular shape (b) is used as a portion for engaging the nipping member 2. Projections from the sinker main body 1 are formed on both the sides of the nipping member 2, and a slit 2b is formed on the center of thickness of the knitting member 2.

れる。[0008] The fishing weight is formed by combining, for example, press-fitting a tub-shaped holding body 2 sliced into a weight body 1 having a spherical outer shape. The weight body 1 is made of a metal having a specific gravity of 7 or more, such as a dangsten, a dangsten alloy, an iron-based metal such as stainless steel, and a copper alloy. For example, if it is a dangsten alloy, W-6Ni-4Cu or W-4.9Ni-2.1Fe
For example, a spherical weight main body 1 having a slot groove 1a is formed by sintering, and cannot be deformed by human force to collapse the slot groove 1a. In addition, the weight body 1 may be formed by mixing a metal powder of the above-described material into a synthetic resin and curing the mixture. The elastic material from which the holding body 2 is formed has a lower hardness than the weight main body 1 and is formed of a material which is easily deformed, and is made of a polymer material such as rubber, synthetic rubber, and synthetic resin.

てもよい。The weight main body 1 is formed with a slotted groove 1a in a sphere, and the slotted groove 1a is formed in a vertical cross section a and a circular arc shape b in a flask shape. The arc shape b is provided at the bottom of the slot groove 1a along the direction in which the fishing line 3 is held, and serves as an engaging portion of the holding body 2. The center of the spherical weight body 1 and the center of the arc shape b are formed at substantially the same position. On both sides of the sliced crab-shaped holding body 2, the weight body 1 is incorporated into the weight body 1.
A protruding portion 2a that protrudes more is formed. A slit 2b is formed in the center of the thickness of the holding body 2. The lower end of the slit 2b is formed so as to reach the center of the circular arc shape b when the holding body 2 is incorporated into the weight body 1. The fishing line 3 is inserted through the slit 2b. An inclined surface for guiding the fishing line 3 to the slit 2b may be provided on the upper edge of the slit 2b.

た部分の釣り糸３が錘本体１に接触することがない。The holding body 2 is a slotted groove 1a of a spherical weight body 1.
When pressed into the slit, it is deformed into a shape that matches the arc shape b due to its elasticity, and the arc shape b prevents the slit from coming off in the opening direction of the slit (the direction perpendicular to the fishing line). When the holding member 2 is pressed into the slot 1a of the spherical weight body 1, the slit 2b is pressed in the closing direction, and the fishing line 3 inserted through the slit 2b is held by the pressing force. When the fishing line 3 is clamped from the spherical weight body 1 to the clamping body 2 and the projection 2a is formed to protrude along the longitudinal direction thereof, the fishing line 3 protruding from the slit 2b does not contact the weight body 1. .

ことで形成しても良い。The shape of the holding body 2 is not particularly limited. The holding body 2 is deformed by being press-fitted into the slot 1a of the weight body 1 to be engaged with the engaging portion. You may shape | mold so that it may have a locking part. The slit 2b of the holding body 2 may be formed by making a cut in the holding body 2 or by folding the holding body 2 into two and pressing it into the slot groove 1a.

止めされているため脱落が防止される。When the fishing weight is constructed as described above, the fishing line 3 can be firmly held by the holding body 2 incorporated in the weight body 1, and the weight body 1 is deformed like a crushing weight. Since the groove does not open and close, it can be used as a fishing weight that is hard to break and can be used repeatedly.
Since the protruding portion 2a of the holding body 2 is formed to protrude from the spherical weight body 1, the fishing line 3 is formed by the slot 1a of the weight body 1.
And the fishing line 3 is prevented from being damaged. The holding body 2 is prevented from falling out in the arc shape b in the weight main body 1, so that the holding body 2 is prevented from falling off.
