Description

[Detailed Description of the Invention] The present invention relates to the shape of a fishhook, particularly the shape of the tip of the hook.

. Conventionally, the tip of a fishhook is usually sharply pointed like a sewing needle.

However, the point of the needle, which is simply pointed in a conical shape, has the disadvantage that it is easily worn out and easily breaks due to snags or the like.

Furthermore, the tip of the needle, which has a circular cross-section, has a relatively large resistance to the direction in which it penetrates when feeding on fish, so it is not always possible to catch fish reliably.

In order to improve these drawbacks, the present inventor first devised a shape in which the tip of the fishhook was cut diagonally (Utility Application No. 55-30391).

This invention takes the basic idea of making one side of the tip of a fishhook flat, making it stronger and without breakage of the tip.
In addition, the shape of the fishhook has been devised so that it can be easily manufactured.

Hereinafter, embodiments of the fishhook of the present invention will be described based on the attached drawings.

A conventional fishhook was bent into a diagonal shape, and the tip of the hook was simply sharpened into a conical shape.

On the other hand, the fishhook 1 according to the present invention has one surface of the hook tip portion A ahead of the vicinity where the return 2 is provided is deformed into a flat surface, and a ridge 4 is vertically provided on the back surface of the flat surface 3. .

Therefore, the cross-sectional shape of the needle tip portion A is approximately T-shaped as shown in FIG. It has a unique shape.

Since the flat surface 3 is simply a deformed needle tip that should be sharpened into a conical shape, it takes on a deformed oblong oval shape with a sharp point (FIG. 3).

Since there are ridges 4 on the back surface of any part of the plane 3, the cross-sectional shape is approximately T until the tip.
It becomes a letter shape.

In the drawings of the embodiment, the inward surface of the needle is referred to as plane 3.
However, conversely, the outward facing surface may be made flat.

With a conventional simple conical needle tip, when piercing the target fish,
There is no cutting effect, and the resistance gradually increases because the fishhook simply pushes forward while spreading, but according to the fishhook of the present invention, the tip edge 5a has three pieces.

Since 5b and 5c have the effect of being pushed apart and cutting at the same time, it is possible to reliably catch the target fish with a smaller force.

Next, regarding the breakage of the needle tip, as can be seen from the fact that the section modulus is much larger than that of a simple circle with the same cross-sectional area in any direction, it is easy to break or bend the needle tip. It can be made durable without being damaged.

To manufacture the fishhook of the present invention, for example, the tip of the needle, which has been sharpened before bending, is placed on a female mold having vertical grooves, and then pressed from above with a flat pressing mold. can be manufactured.

As described above, compared to conventional fishing hooks, the fishing hook of the present invention has extremely less breakage of the tip and can cut sharply into the target fish, making it durable and durable for long-term use. There is an effect that can be done.
