DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in burrs formed at the tip of a fishing hook.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5, a conventional fishing hook (B) has a sharp burring (12) formed by cutting and raising the inside of the tip of a fishing hook body (11). Such a conventional hook (B)
The following problems occur when fishing is performed by using When live bait is attached to the fishing hook (B), the fishing line is tensioned when the rod is shaken and thrown into the sea, the live bait itself is shocked at that time, damaging the live bait, or the live bait itself into which the hook is inserted May be hurt. In particular, sharp burrs (12) bite into live bait and
When the force is applied in the direction in which the live food comes out from (B), the problem is that the sharp burrs (12) in the above case enlarge the wounds of the internal organs of the live food and weaken the live food. There is.

[0003] When a fish hook (B) hits a fish biting the bait, the tip (17) of the hook (B) is caught in the mouth of the fish, and then penetrates the hard oral surface of the fish to form the tip of the needle.
(17) tries to dig into the mouth of the fish. At that time, when the fish rampages, the angle between the plane (13) of the surface of the needle tip (17), which has been shaved to form the sharp burrs (12), and the back (14) of the burrs (12). (γ) is as very small as 40 ° and the width of the base (k) is narrow, so that the base (k) of the burrs (12)
There was also a drawback that impulsive stress was applied to the corner (15) of the frame and the burrs (12) were easily broken.

Further, when the fishing hook (B) is thrown into the point by shaking the rod, the fishing hook (B) may be erroneously caught on the clothes. However, the conventional sharp burrs (12) [in FIG. Show. ], There is also a problem that the needle tip (17) is very difficult to remove from the clothes because the fibers are stabbed deeply in the clothes and become entangled.

[0005]

The problem to be solved by the present invention is that the live bait is less likely to be weakened by piercing a hook or throwing a hook into a point with live bait inserted. Another object of the present invention is to develop a fishhook that can withstand the breakage of burrs due to the impact of a fish hit and that can be easily removed even when entangled in clothes.

[0006]

A fishing hook according to claim 1.
(A) shows the tip of the needle that was cut off to form the burrs (2).
Plane (3) of the surface (3) of (7) and back (4) of the burrs (2)
Is in the range of 75 ° to 110 ° ”.

According to this, when live bait is stabbed into the hook (A), the tip (7) of the hook (A) digs into the live bait. It will be stabbed inside. In the present invention,
Since the formation angle (θ) of (2) is standing with respect to the shaved surface (3) of the needle tip (7), even if the fishing hook (A)
Even if force is applied in the direction from which the live bait escapes, the burrs (2) do not cut through the internal organs of the live bait, and do not hurt the live bait.

[0008] Claim 2 is that "Kaeri (2) is half thread"
It is characterized by things. The fishing hook (A) in claim 1 does not have to be half-threaded, but if it is half-threaded, the fishing hook (A) is
Since (2) is small, it does not hurt the live bait, and the impact force applied to the burrow (2) when hitting is small, and the burrow (2) does not break at all. Furthermore, it is easy to remove even when it is tangled in clothes.

(Embodiment) Hereinafter, a hook according to the present invention will be described.
(A) will be described with reference to the drawings. In the hook (A) of the embodiment, as shown in FIG. 1, a burr (2) is formed by shaving and raising an inner surface side of a hook tip (7) of a hook main body (1) with a cutting tool (8). . At this time, the scraping plane (3) of the needle tip (7)
The angle (θ) between (2) and the back surface (4) is 75 to 110 °. The material (S) of the hook (A) may be a material such as high-speed steel that has been conventionally used, or a material such as high-carbon steel or titanium, and the material is not particularly limited.

Next, a method for manufacturing the fishing hook (A) of the present invention will be briefly described. The raw material for fishing hook (S) is cut into a predetermined length, one end (6) is sharpened and sharpened, and the other end is pressed to form a thymoto (10). After that, the needle tip
One surface of (7) is shaved with a knife (8) to form a burr (2). At this time, by adjusting the cutting edge angle of the cutting tool (8), the scraping plane (3) of the needle tip (7) and the back of the burrs (2)
The angle (θ) made with (4) is in the range of 75 to 110 °.
Also, the height of the burrs (2) is set to be lower than the height of the conventional burrs (12), so that it is a so-called "half thread" burrs (2). By doing so, the angle of the top of the burrow (2)
(α) is larger than the angle (β) of the top of the conventional burrs (2 ′).

After forming the "half-threaded" burrs (2) in this manner, bending the burrs with the burrs (2) formed inward,
The shape is as shown in FIG. Finally, a predetermined heat treatment is performed to impart sufficient toughness and hardness. Although the case of “half thread” has been described in the above case, the burrs (2) of the present invention are naturally applicable even if they are not “half thread”.

Next, an example of use of the fishing hook (A) according to the present invention will be described. A weight, float, and other necessary devices are attached to a fishing line (not shown) attached to a rod (not shown), and the end of the fishing line (A) is tied to the chimoto (10) of the hook (A). The fishing hook (A) prepared in this way is stuck into the live bait so that the burrs (2) sufficiently enter the live bait. As described above, the burrs (2) are small in the "half-thread" state, so they enter the inside without much damaging the live bait.

Subsequently, the fishing hook (A) with bait is thrown at the point aimed at by shaking the rod, and the hook (A) connected to the fishing line moves from backward to throwing in accordance with the movement of the rod. At that point, the fishhook turns
The live bait attached to (A) receives a shocking force in the direction of dropping from the hook (A),
(2) tries to move in the falling direction in the live bait.

At this time, the frog (2) engages with the internal organs, muscles and other internal tissues of the live bait to prevent the live bait from dropping off from the hook (A). It means damaging the tissue and weakening the live food. In other words, if it has a sharp tip like the conventional burrs (12), the internal organs of the live food will be cut into shreds and the live food will be weakened quickly, but as in the present invention, the `` half '' In the case of a squirrel (2) with a slanted (α) peak, it does not shatter the live food's internal organs and does not weaken the live food.

As described above, when the hook (A) with bait is thrown into the point and the rod is moved to invite the fish, the fish sometimes come to eat. The fish is hit by operating the rod at that timing, but at the same time as the hit, the fish tries to escape from the hook (A) and swims in the opposite direction at a rapid speed.

At this time, the tension applied to the fishing line and the force for the fish to escape combine to apply a shock to the fishing hook (A). This impact force is mainly applied to the fishhook (A) as a force in a direction in which the curvature of the protruding portion of the hook (A) is extended,
At the same time, as a normal case, the needle tip (7) penetrates deeply into the oral cavity, including the burrs (2).

At the next moment, the fish swims in all directions in order to escape from the hook (A). At this time, depending on the direction, a force may be applied in a direction in which the hook (A) comes out of the fish. In such a case, intensive force is applied to the burrs (2) engaged with any of the hard oral cavity of the fish.

This force is applied from the rear surface (4) of the burrs (2) in a cut-and-raise direction, so that the burrs (2) are shocked to escape from the base (K) in a direction to break the burrs. It acts as stress.

In the conventional burrs (12), as can be seen from FIG. 5, the rear surface (14) of the burrs (12) and the scraping plane of the needle tip (17).
Since the angle (γ) between (13) and (13) is small, all the forces applied to the back (14) are applied to the corner (15) of the base (k) of the burrs (12) and try to raise the burrs (12) Direction, and as a result, the burrs (12) often cracked from the corners (15) of the base (k) due to the cracks and the narrow width of the base (k). .

On the other hand, in the case of the fishhook (A) of the present invention, the angle (θ) is large, so that the greater the impact stress, the more it escapes along the back surface (4) and the back surface (4) The direction of the force applied is not concentrated on the corner (5) of the burrs (2) as in the prior art. In addition, since the width of the base (K) is large, even when an impact force is applied to the burrs (2), the burrs (2) do not break.

Further, when the fishing rod (A) is thrown into the point by shaking the rod, the fishing hook (A) may be erroneously hooked on the clothes of the angler. If the angle (γ) of (14) is small, the burrs (12) are stuck deeply in the clothes and become entangled, and even if you try to pull out the needle tip (17), the fibers of the clothes enter along the back (14). Although it was not possible to move to the corner (15) side and pull it out, in the case of the burrs (2) as in the present invention, the back surface (4) slips toward the top side and easily comes off. As a result, the hook (A) pierced into the clothes and entangled can be easily extracted.

[0022]

According to the present invention, as described above, the angle between the flat surface of the needle tip and the rear surface of the burrs is 75 ° or more.
Because it is formed as large as 110 °, there is an advantage that it is difficult to weaken the live bait even if the needle tip part is inserted into the live bait, and the burrs do not break even against the impact when hitting the fish, There is no escape of fish. Further, there is an advantage that even when the needle tip is entangled with the clothes, it can be easily removed.
