Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fishing balance connected between a fishing line and a Harris.

[Prior art and its problems] Conventionally, as shown in Fig. 3, a balance among fishing equipment is made by connecting wires 1 and 2 with a thickness of about 1.5 mm through a cable hook 3, and connecting the wires 1 to A weight 4 is slidably inserted therethrough. A thread 5 is connected to the other end of the wire 1 via a sag 6 for twisting, and a Harris 7 is similarly connected to the other end of the wire 2 via a shim 8 for use. In this way, conventional balances were constructed so that they could be bent freely at Sarkane 3, but since wires 1 and 2 were generally made of mild steel, their plastic properties were superior. When bent by external force, it does not return naturally to its original straight shape. For this reason, if some external force is applied to the bending part, the bent part will become curly and will not return to its original shape, making it difficult for the weight 4 to slide freely, which will impede its use. It was hot.

In addition, since the rigidity of wire 1 and wire 2 is strong,
There was a problem in that the balance easily became entangled in rocks, etc., and when it became entrenched, it could not be easily removed and the line 5 broke, resulting in the loss of the device (the balance and the fishhook).

[Means for Solving the Problems] The present invention is an attempt to solve the above-mentioned problems, and includes forming a thread joint part and a Harris joint part at both ends of a wire made of a shape memory alloy, respectively. This fishing balance is characterized in that a weight or a weight attachment member for sliding a wire rod and a stopper for regulating the sliding range of these weights are attached to the wire rod.

[Function] Alloys such as TiNi, Cn ₃ Aτ, and AnCd have the unique property of returning to their original shape when heated to a predetermined temperature even if they are deformed at room temperature. As is well known, these alloys have shape memory. Although it is called an alloy, in this invention, by making a fishing balance using a wire rod made of the shape memory alloy, we provide a product that has strong shape recovery properties against bending and has moderate elasticity and is difficult to get entangled. This is what I am trying to do.

[Example] Fig. 1 shows an example of a fishing balance according to the present invention. In the figure, 10 is a TiNi alloy wire rod with a diameter of 0.6 mm, one end of which is connected to a road thread 12 via a sag ring 11 and a joint ring 17, and a Harris 14 is connected to the other end via a sag ring 13. There is. A weight 15 is slidably inserted through the wire 10, and a stopper 16 is fixed to a substantially central portion of the wire 10 in order to limit the free sliding range of the weight 15. This TiNi alloy wire rod 10 of about 0.6 mm has appropriate elasticity even at room temperature, so it can be bent appropriately without intervening a sulcan in the middle like a conventional balance, so that when the Harris 14 is thrown in, the line 12 You can prevent it from getting tangled in water, and it can also prevent it from getting rooted. Then, the wire rod 10
If the wire rod 10 is bent due to some external force, it can be easily returned to its original straight shape by soaking the wire rod 10 in hot water or roasting it with a torch or the like. .

Another embodiment of the present invention, shown in FIG. Although the weight is attached and replaceable, the present invention can also be applied to such a type of balance by making the wire 10 made of a shape memory alloy such as a TiNi alloy.

[Effects of the invention] As explained in the above embodiments, the fishing balance of the invention is made of a wire rod made of a shape memory alloy, so it has high elasticity at room temperature, and there is no need to interpose a sulcan in the middle part. By selecting the wire diameter, you can obtain the necessary and sufficient curvature to prevent the yarn from getting tangled, and even if it bends due to some external force, it can be easily restored to its original shape by heating with hot water, fire, etc., and will last for a long time. It is a useful thing that can maintain its function.
