Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a squid fishhook, and more specifically, to an improvement in a squid fishhook in which an umbrella-like needle body is embedded and integrated into one side of a rod-like bait body.

(Prior art and its problems) There are various types of synthetic resin rod-shaped baits with umbrella-shaped needles attached to them, but at first, nylon threads were used to attach umbrella-shaped needles to rod-shaped baits. It used to be established by winding a thread, but due to the difficulty of assembly work, in recent years, when molding rod-shaped bait objects, an umbrella-shaped needle body is set in the molding die, and the structure is integrally molded by embedding it. It is being

As shown in FIG. 3, the vertical rod portion 5b of the umbrella-like needle body 5 embedded and fixed in the rod-like bait object 4 has approximately the same length as the length of the needle rod portion 5a that expands radially upward. Therefore, the length of the buried vertical rod is longer, and the outer diameter of this part is also thicker than other parts (the part where the vertical rod is not located), so that the rod-shaped lure is buried slightly above the vertical rod. The outer diameter of the body is considered to be small.

Therefore, when the above-mentioned squid fishhook is connected to a fishing line and mechanically fished, it is pulled up by the rotation of the hoisting drum, but at this time, the weight and The rod-like bait body curves and the fishhook is pulled up as it is stretched downward. However, because the length of the vertical rod of the umbrella-shaped needle buried and fixed in the rod-shaped lure is long, breakage is likely to occur at the boundary between the large diameter part of the buried part and the small diameter part above it. It is something. This phenomenon occurs because the length of the vertical rod portion and the length of the needle rod portion are approximately the same, and the shaft diameter of the buried portion of the vertical rod portion is larger than the shaft diameter of other portions, making it difficult to bend. Since the tip of the umbrella needle comes into contact with the circumferential surface and serves as a fulcrum for curvature, bending occurs slightly above the tip of the umbrella needle.

(Problems to be Solved by the Invention) In view of the conventional circumstances as described above, the present invention has been developed in such a way that even if the tip of the umbrella needle comes into contact with the circumferential surface of the drum and this part becomes a fulcrum for bending, the rod-shaped artificial bait The purpose is to prevent damage to the body.

(Means for solving the problem) The technical means taken by the present invention to solve the above problem is to reduce the length of the vertical rod of the umbrella-like needle embedded and fixed on one side of the rod-like bait object. The length is approximately half the length of the needle rod part, and the bait shaft diameter in the upper part of the buried part is made smaller.

The number of umbrella-shaped needle bodies embedded and integrated into the rod-shaped bait body is 1.
Of course, it is also possible to have a structure in which the needles are attached in two stages, upper and lower, at a predetermined interval, and in that case, the above-mentioned structure is applied to the embedded fixing part of each needle body.

(Function) According to the above configuration, the vertical rod portion of the umbrella-like needle body embedded and integrated into one side of the rod-shaped lure made of synthetic resin is approximately half the length of the needle rod portion, and the vertical rod portion is approximately half the length of the needle rod portion. Because the part has a small diameter shaft, even if the tip of the umbrella-shaped needle comes into contact with the outer peripheral surface of the hoisting drum and serves as a fulcrum for bending, the vertical rod embedded in the rod-shaped bait Since the length of the rod-like bait part is short, the rod-like bait part located between the upper and lower ends of the needle-rod part can also be bent, thereby preventing the rod-like bait from breaking.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. A squid fishing hook A is a rod-shaped bait object made of synthetic resin 1.
and a rod-shaped body 2 fixed to one side (lower end) of the rod-shaped lure 1.

The rod-shaped bait object 1 is formed into a rod shape using thermoplastic synthetic resin, thermosetting resin, or synthetic resin, and its cross-sectional shape is circular or approximately diamond-shaped, and fishing line passing holes 3, 3' are formed in the upper and lower parts. , an umbrella-like needle body 2 is fixed at a position immediately above the lower fishing line passing hole 3'.

The umbrella-shaped needle body 2 has a form and structure well known in this technical field, in which the needle-pull part 2a is inclined at a desired angle, and the length of the vertical rod part 2b embedded and integrated in the rod-shaped bait object 1 is the same. The length is approximately half the length of the needle rod portion 2a, and the vertical rod portion 2b is embedded and integrally fixed in the upper position of the lower fishing line passage hole 3' of the rod-shaped bait object 1.

The diameter of the shaft at the buried portion of the vertical rod portion 2b is made larger than that at other portions that are not buried, so that the bending action can be effectively performed at the small diameter shaft portion that is not buried.

Fig. 2 shows a fishhook in which the umbrella-shaped needle bodies 2 are attached in two stages, upper and lower. The axial diameter of the rod-shaped bait object 1 between the needle bodies 2 and 2 is made small like the part of the vertical rod part 2b that is not buried.

With the above configuration, the rod-like bait object 1 can be bent between the lower end of the vertical rod part 2b and the tip of the needle rod part 2a in the umbrella-like needle body 2, and the problem of breakage can be prevented.

(Effects of the invention) As described in detail above, the squid fishing hook of the present invention is a squid fishhook in which the vertical rod of the umbrella-shaped needle is embedded and integrated into one side of the rod-shaped lure. The length is approximately half the length of the needle rod part, and the part above the buried part is a small diameter shaft part, so that the rod-like bait object extends from the lower end of the vertical rod part of the umbrella-shaped needle body to the tip of the needle rod part. bending is possible between the two.

Therefore, even if the needle tip of the umbrella-like needle comes into contact with the circumferential surface of the hoisting drum and serves as a fulcrum for bending, the amount of embedding of the vertical rod is small as described above, and the length of the needle rod is Since the bending is performed within the range of , it is possible to eliminate the problem that occurs in conventional squid fishing hooks where the rod-shaped bait object breaks at a position slightly above the upper end of the vertical rod portion.

Therefore, it is possible to provide a highly practical fishing hook that can withstand long-term use.
