Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hollow guide wire that penetrates the inside of, for example, a fishing rod.

[0002]

[Prior art]

 Generally, a fishing rod using a reel has a plurality of loop-shaped guides. However, if there is a guide, the fishing line tends to get entangled in the tips, and when the guide's legs are pulled or throwing is performed, the original condition is often lost. In order to improve this, a so-called middle fishing rod in which the guide is removed and the fishing line is passed through the inside of the rod has been proposed (Japanese Utility Model Laid-Open No. 5-23866), and the number is rapidly increasing.

Conventionally, as the hollow guide wire used for the hollow fishing rod, dozens (for example, about 50) of fine metal wires are twisted and used.

[0004]

[Problems to be solved by the device]

 However, the twisted yarn of the conventional ultrafine wire is usually wound in a loop shape and stored, but if it is taken out at the time of use, there is a problem that curling is left and it becomes difficult to pass the thread. In particular, since the hollow hole of a hollow fishing rod has a diameter of about 1 to 1.5 mm, it is difficult to hollow the fishing rod if there is any unwinding curl. In addition, when used repeatedly several times, linearity is lost due to kinks, curls, and the like, and there is a problem that it is difficult to thread the center.

In order to solve the above-mentioned conventional problems, it is an object of the present invention to provide a centering guide wire that does not leave a curl when used and allows easy centering.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first middle guide wire of the present invention is a middle guide wire formed by twisting a plurality of metal wires. The outer peripheral portion is covered with a synthetic resin so as to be integrated, and at least one end of the plurality of metal wires has a loop formed therein, and a stop portion for fixing the loop is wound with a fiber yarn. It is characterized by being

In the above structure, it is preferable that seven metal wires are formed and one cross section perpendicular to the length direction is arranged in the central portion and six cross sections are arranged around the cross section. Further, in the above structure, the metal wire is preferably stainless steel or a shape memory alloy. Further, in the above-mentioned configuration, it is preferable that the coating resin of the stop portion that fixes the loop is removed.

Next, the second middle guiding wire of the present invention is a middle guiding wire made of one shape memory alloy, and the outer peripheral portion of the shape memory alloy wire is coated with a synthetic resin. Further, a loop is formed on at least one end of the wire, and the coating resin of the stopper for fixing the loop is removed, and a fiber thread is wound on the surface of the wire.

[0009]

[Action]

 According to the configuration of the first invention of the present invention, the outer peripheral portions of the plurality of metal wires are covered with the synthetic resin so as to be integrated, and at least one end of the plurality of metal wires is a loop. Since the stopper for fixing the loop is wound with the fiber yarn, it is possible to realize an inner thread guide wire that can be easily threaded without leaving a curl during use. Further, even if it is repeatedly used many times, the linearity is not lost, and even if it is a thin hollow hole having a diameter of about 1 to 1.5 mm, it is easy to pass through it.

Further, according to a preferable configuration in which seven metal wires are formed and one of which has a cross-sectional shape perpendicular to the length direction and the other of which has six wires arranged in the central portion, Close to filling, less wasted space, and improved linearity.

When the metal wire is stainless steel, rust is less likely to occur and it is suitable for connecting a fishing line that is often in contact with water. Further, the shape memory alloy further improves the linearity. Here, as the shape memory alloy, any known alloy such as a Cu alloy represented by a Ni—Ti alloy or a Cu—Zn—Al alloy may be used. Further, if the coating resin of the stopper for fixing the loop is removed, the number of protrusions is reduced, and the threading is further facilitated.

According to the configuration of the second aspect of the present invention described above, the outer peripheral portion of the single threading guide wire made of a shape memory alloy is coated with a synthetic resin, and at least one end of the wire is A loop is formed, and the coating resin of the fixing part that fixes the loop is removed and the fiber thread is wound on the surface, so there is no curl at the time of use and it can be easily threaded. Can be realized. Further, even if it is repeatedly used many times, it does not lose its linearity, and even if it is a thin hollow hole having a diameter of about 1 to 1.5 mm, it is easy to pass through it.

I was able to. In addition, even if it was repeatedly used, no twisting occurred, linearity was not lost, and even hollow hollows were easy to pass through. In addition, there was no catch in the loop fixing part, allowing smooth insertion.

Example 2 Seven commercially available wires of stainless steel (SUS316, diameter 0.128 mm) were used, and one wire was twisted so that six wires were arranged around the wire. The number of twists is 200 per 1 m. Then, it was immersed (dipped) in molten nylon (nylon-6,6) and coated while controlling the adhesion amount so that the dry weight was 1.63 g per 1 m.

Next, cut to 1.6 m, make a loop at the tip, peel off the nylon coating with a length of 5 mm only at the stop, and then peel off the nylon-6,6 multifilament yarn (110 denier). , 20 filaments), and finally a drop of instant adhesive was dripped and fixed.
