Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to fishing weights, and particularly to fishing weights that can be used in fishing spots where there are obstacles such as rocks on the bottom of the water where the weights can easily get caught. Concerning dust.

PRIOR ART AND ITS PROBLEMS For deep-water fishing in rivers, lakes or the ocean, a sinker is usually attached to the end of a fishing line to facilitate sinking the bait to a desired depth in the water. It will be done. However, conventional sinkers tend to get caught on underwater rocks and other invisible obstacles, which annoys anglers, who often have to cut the fishing line and abandon the sinkers.

A conventional weight, as shown in FIG. 1, consists of a generally olive-shaped piece of lead A having a longitudinal through hole B extending from one end thereof to the other.

In use, as shown in FIG. 2, the fishing line C is passed from one end of the lead strip A through the longitudinal through hole B, folded back at the other end, and tied at one end. When this weight is hooked to a rock at the bottom of the water, as shown in Figure 1, the pulling force is exerted directly on the lead piece A, without the piece A itself rotating or pivoting to release itself from the hook. Therefore, even if fishing line C is pulled, the weight hanging on the layer cannot be released.

OBJECT OF THE INVENTION In view of the above-mentioned problems of conventional fishing weights, it is an object of the present invention to provide an improved fishing sinker which can avoid catching on obstacles such as underwater rocks and other unknown objects. Our purpose is to provide fishing weights.

(Configuration, Effects) The weight according to the present invention consists of an elongated capsule having two generally rounded ends and one or more lead pieces loosely housed within the capsule. The capsule is
It consists of a main body having an open end and a cap that is fitted to the open end of the main body in a watertight manner. An ear with a hole for connecting the capsule to the end of the fishing line is formed on the outer side near one end of the capsule. Because the capsule takes in air when the lead piece is sealed inside of it, the capsule tries to maintain an upright position in the water, and this upright position reduces the chance of snagging on rocks or other obstacles when the fishing line is pulled. Reduce.

Even if this weight encounters an obstacle, the force of pulling the fishing line causes the capsule to rotate or pivot around the obstacle, preventing it from becoming hooked on the obstacle.

(Embodiment) As shown in FIG. 3.4, a first embodiment of the present invention includes a main body 10, a cap 20 fitted to the main body 10 to constitute a watertight enclosure, and It consists of one or more weight pieces or lead pieces 30 loosely housed in a capsule l which is a watertight enclosure. The body 10 is preferably formed from a relatively hard plastic material into a bullet-shaped container having a generally rounded bottom or closed end 15 and an open end 14, and an open end of the body 10. 14
Extending from the proximate outer surface are ears 13 having holes 11 to facilitate attachment of the capsule to fishing line. The cap 20 includes a dome-shaped top 23 and a generally cylindrical skirt 24 extending from the top 23 to fit into the open end 14 of the body 10 . It has a longitudinal sloft 22 to impart stiffness to the skirt portion to ensure proper frictional engagement with the inner surface of portion 14. The skirt portion 24 further fits into a hole 12 formed in the upper portion of the body 10 to lock the cap 20 in place. It includes a protrusion 21 extending laterally.

Skirt portion 24 engages open end 14 of body 10 in a watertight manner so that air is sealed within the capsule when camp 20 is attached to body 10. A suitable number of lead pieces is placed within the capsule 1, leaving sufficient space for an air reservoir.

In order to use the weight shown in FIG. 3, the fishing line C is first connected to the ear portion 13 of the main body 10 as shown in FIG. When a weight is thrown into the water with a baited fishing rod,
Since the lead piece inside the capsule 1 tries to stay in the lowermost part of the capsule and the air inside the capsule tries to make the upper part of the capsule rise as shown in FIG. Try to maintain your posture.

When the weight is pulled by a fishing line so as to move it through the water, the weight, which is loosely contained within an elongated capsule and has a piece of lead that tends to remain in the lower part of the capsule, is tilted or moved. An inclination angle A is maintained with respect to the direction. This angle of inclination helps the weight to rise hydrodynamically.

When the weight is moved along the bottom of the water and is pulled by the fishing line so as to encounter obstacles such as rocks, the weight should be easily caught in the obstruction, as shown by the dashed line in Figure 6, in order to avoid getting caught on the obstruction. Be rotated or pivoted around an object.

If the weight is lying on the bottom of the water and is pulled by the fishing line as it moves along the bottom of the water and encounters an obstruction and the weight fails to maintain an upright position as shown in Figure 7, the weight is It can be pivoted around obstacles, as shown by the dashed line in FIG. 7, without getting caught. This allows the piece of lead contained within the capsule to move freely within the capsule from one end of it to the other, and this free movement facilitates the movement of the weight's center of gravity, causing the weight to move around obstacles. This is because it facilitates pivoting.

Instead of frictional engagement, the cap 20 and the main body 10 have an eighth
As shown in the figure, the skirt portion 24 of the cap 20 is provided with female threads 24A, and the inner side of the open end 14 of the body 10 is provided with male threads to form a watertight connection. Female screw 14A that cooperates with 24A
Equipped with.

Although a plurality of relatively small lead pieces 30 are illustrated, a relatively large single lead piece may be used instead.
