Description

[Detailed description of the invention] The present invention has a grip part with a diameter larger than the diameter of the base end at the base end of the main rod, specifically the hollow rod body which tapers in a tapered manner with a small taper angle with a small rate of change in diameter. The present invention relates to a base rod which is provided so that the grip portion can be easily gripped.

Generally, in this type of original rod, when the grip part is made to have a larger diameter than the diameter of the proximal end of the rod body, a string-like material such as thread or tape is used to fill the outer periphery of the proximal end of the rod body. It is wrapped in a tapered shape and shaped into a size that is easy to grip.

However, according to this conventional structure, it takes a lot of effort to form the grip, and not only is the workability very poor, but when fishing while gripping the grip,
When the fish bites the bait, the hit is transmitted to the hand through the filling, so a portion of the hit is absorbed by the filling, resulting in a poor hit response and a delay in the timing of retracting the fishing line, resulting in poor fishing results. There is a problem with this, and since it is a structure that uses filling,
There was a problem that the strength was small relative to the diameter, and it was also heavy.

The present invention was devised in view of the above points, and the purpose is to use prepreg to form a hollow rod body that tapers in a tapered manner with a small taper angle with a small rate of change in diameter. By integrally forming the grip portion through a tapered portion continuous with the base end portion of the grip portion, the above-mentioned filling is eliminated and the above-mentioned problem is solved.

The structure of the present invention is to form a hollow rod body that tapers into a tapered shape with a small taper angle with a small rate of change in diameter by winding prepreg made of high-strength fibers and impregnated with synthetic resin, and at the base end of this rod body, The base rod is provided with a grip portion having a diameter larger than the diameter of the base end portion, which is continuous with the base end portion of the rod body by the prepreg, and has a thickness that is approximately the same as that of the base end portion of the rod body, and has a grip portion that is larger in diameter than the diameter of the rod body. a long tapered part that expands in diameter with a gentle slope slightly larger than the rate of change and has no step between it and the rod body; The grip part is formed integrally with the base end part of the rod body, and the grip part has a substantially linear shape with no step between the grip part and the grip part, and the grip part can be formed in a straight line and of a thickness that is easy to grip. It is relatively easy to work with, has high strength, is lightweight, and has a good response when hitting.

An embodiment of the original rod of the present invention will be described below based on the drawings.

The main rod shown in Fig. 1 has three hollow rods that are tapered at a taper angle that has a small rate of change in diameter, and a hollow rod body 1 that is tapered at a taper angle that has a small rate of change in diameter. Intermediate rods 2, 3, 4 and one tip 5
The rod body 1 is provided with a grip portion 13 having a diameter larger than that of the base end 11 at the base end 11 of the rod body 1. Further, the main rod is formed hollow by wrapping prepreg, which is formed by impregnating a synthetic resin in a high-strength fiber aligned sheet or woven sheet with a synthetic resin, around a core bar and pressurizing and heating it, for example, as in the past. It is.

In this way, the prepreg forming the rod body 1 is continuous with the proximal end 11 of the rod body 1 with approximately the same thickness, and expands in a gently sloped shape that is slightly larger depending on the rate of change in the diameter of the rod body 1. A long tapered part 12 having a diameter and having no step between it and the rod body 1, and a continuous taper part 12 with approximately the same wall thickness as the tip of the tapered part 12, and a step between it and the tapered part 12. The handle portion 13, which has a substantially linear shape without a ridge, is integrally formed with the base end portion 11 of the rod body 1.
Furthermore, specifically, while forming the prepreg to a length required to form the rod body 1 plus the lengths of the tapered part 12 and the grip part 13, A core metal consisting of a molded part sized to fit the inner diameter of the rod body 1, and a molded part sized to fit the inner diameters of the tapered part 12 and the grip part 13, which have the same wall thickness as the rod body 1, is used. By wrapping the prepreg around this metal core and heating it under pressure, a tapered part 12 having the same thickness as that of the rod body 1 and a substantially linear grip part 13 are formed on the base end part 11. It is formed in one piece.

In addition, 6 in the figure is a butt plug attached to the end opening of the grip part 13, and is formed by a closing part 61 and hawk-shaped locking pieces 62, 62. Also, 1
4 is a locking hole provided at the distal end of the grip portion 13; 7;
is a reinforcing ring.

As described above, the present invention involves winding a prepreg made of high-strength fibers impregnated with synthetic resin to form a hollow rod body that tapers at a taper angle with a small rate of change in diameter. , a base rod comprising a grip portion having a diameter larger than the diameter of the base end portion, which is continuous with the base end portion of the rod body by the prepreg, and has a thickness that is approximately the same as that of the base end portion of the rod body; a long tapered part that expands in diameter with a gentle slope slightly larger than the rate of change of and has no step between it and the rod body; The rod body is characterized in that the substantially linear grip portion having no step between it and the tapered portion is integrally formed at the base end portion of the rod body, so that the substantially linear grip portion can be gripped. Therefore, the grip part is very easy to grip, and it is less slippery than a grip part formed in a tapered shape, so there is no need to provide an anti-slip member on the outer peripheral surface of the grip part. There is also less fatigue in the hand holding it. Furthermore, since the substantially linear grip portion is formed by winding the prepreg used to form the rod body, it can be formed simply and easily, which makes it easier to work with and can be provided at a lower cost. be.

In addition, the small-diameter base end and the large-diameter grip are made to be continuous with almost the same thickness by the prepreg that makes up the rod body, and the continuous taper part is gently sloped and long. Since the shape has no steps or differences between the rod body and the grip, the above-mentioned shape has no steps or differences between the rod body and the grip, even though the different spans are continuous with approximately the same thickness using prepreg. The tapered part can alleviate stress concentration and disperse stress, and the rigidity of the proximal end of the rod body can be continuously changed toward the larger diameter, increasing the strength relative to the diameter. Moreover, it can be made lightweight, and since there is no filling in the grip, the angler can feel the hit when fishing, and can increase fishing results.
