JP6669441B2 - Grip structure for fishing rod and fishing rod - Google Patents

Description

  The present invention relates to a grip structure for a fishing rod used for jigging fishing and the like, and a fishing rod.

In jigging fishing, a lure hanging from a pole tip is moved up and down in the sea to invite a fish to catch it. Therefore, when lifting the lure, the fishing rod is in a bent state in which a large arc is formed around the hand-side rod body portion held by the angler, and when the lure is settled, the arc is loosened while loosening the arc. Return to the state. Such a change is repeated according to the vertical movement of the lure.
Therefore, when the entire fishing rod is bent without stretching when the fishing rod is to be lifted, the burden on the angler holding the rod at the hand side is reduced, and the fishing feeling is improved.

  In the fishing rod described above, a mounting seat is formed at a predetermined position of the proximal rod body in order to improve the strength of the proximal rod body part to which the reel seat is attached. As this mounting seat, there was a seat formed by winding a prepreg base sheet around a plurality of plies on the outer peripheral surface of a rod body.

JP-A-2006-166841

Although the above-mentioned mounting seat is limited to the reel seat portion, for the purpose of also strengthening the rear grip portion, as shown in FIG. In some cases, the pedestal sheet 12 is wound, and the sheet surface 12C is formed linearly with the same diameter until it reaches the rod base end by centerless processing.
When a fishing operation is performed using this fishing rod, a step between the rod end side end of the mounting seat formed by winding the pedestal sheet and the outer peripheral surface of the rod body is formed due to long-term use. In some cases, cracks d occurred in the front side portion 12a.
In such a case, it is conceivable to apply a prepreg reinforcing sheet made of glass fiber to the site where the cracks occur. However, there is a concern that the structure is complicated and the weight may be increased, which is against the demand for weight reduction.

  On the other hand, it is important to apply the technology from the aspect of strengthening the reel seat mounting part, but as another aspect, when performing the operation of inviting fish by raising and lowering the fishing rod or extracting the fish In addition, it is necessary to be able to draw a smooth arc without angle as the posture of the fishing rod. The arc is the same for the reel sheet portion. For example, if only the reel seat portion has a linear shape like one side of a hexagon, the portion is in a stretched state, and it becomes difficult to perform a smooth fishing operation.

In such a case, as described above, the rod material 1A (shown in FIG. 5) that has been wound around a mandrel and fired is used in order to eliminate a step that is considered to have caused a crack. Use as the rod body 1 is also conceivable. In this case, there is certainly no large-diameter bulging portion called a mounting seat, and the outer peripheral surface of a gentle taper (1-2 mm / 1000) in a state of being wound around a mandrel over the entire length of the hand side rod body. Therefore, the occurrence of cracks as described above is suppressed.
However, in the mounting part of the reel seat, it becomes a fulcrum for the angler to support the fishing rod, so from where the load concentrates, it is conceivable that the mounting part has insufficient strength, so it is necessary to take some measures. Was.

  An object of the present invention is to provide a grip for a fishing rod capable of performing a jigging operation lightly while avoiding the above-mentioned inconveniences and exhibiting stable performance even for long-term use.

  As described above, the rod material 1A on which the reel sheet and the like are mounted is as follows. Although not shown, a prepreg sheet is formed by impregnating a thermosetting resin such as an epoxy resin or a phenol resin into a reinforcing fiber group in which reinforcing fibers such as carbon fibers are aligned in one direction. For example, when the rod material 1A is made by winding a prepreg sheet in three layers, a prepreg sheet in which reinforcing fibers are aligned in the circumferential direction is wound around a mandrel, and the reinforcing fibers are drawn in the axial direction from above. The aligned prepreg sheet is wound, and further, the prepreg sheet in which the reinforcing fibers are aligned in the circumferential direction or the axial direction is wound.

A polyester tape (not shown) is spirally wound therefrom without any gap, fired in a firing furnace while being wound around a mandrel, then the polyester tape is peeled off, the mandrel is removed, and the rod material 1A is taken out. .
The rod material 1A thus formed has a tapered outer peripheral surface of about 1-2 mm / 1000 mm from the rod tip end to the rod base end.

The tapered mounting seat 11 for a reel seat will be described. As shown in FIG. 7, a base sheet 12 made of prepreg is wound around a rod material 1A that forms the hand-side rod body 1. The pedestal sheet 12 has a trapezoidal shape, and one side 12A of the rod tip is cut so as to be inclined with respect to the axis, and the other side 12B of the rod base side is cut so as to be orthogonal to the axis. .
Such a pedestal sheet 12 is wound around the rod material 1A from the reel sheet attachment site to the rod base end. The number of windings is 2 to 5 plies, and the number of plies tends to increase as the rod diameter increases.

The direction of the reinforcing fibers c in the pedestal sheet 12 is set to be inclined with respect to the rod axis X. Thus, when the rod bends, the state in which the portion of the pedestal sheet 12 becomes resistant to bending can be reduced as compared with the case where the rod is bent along the axial direction, and a more flexible rod can be obtained. .
As long as it is inclined with respect to the rod axis X, the reinforcing fibers c may be woven into a cloth, or a prepreg sheet in which the reinforcing fibers c are aligned in one direction may be crossed with each other. In this case, a bias type superimposed may be used.
Furthermore, the direction of the reinforcing fibers c may be aligned along the rod axis X, or may be along a circumferential direction perpendicular to the rod axis X.
Moreover, although the prepreg is used as the pedestal sheet 12 by impregnating the reinforcing fiber c group with a resin, a nonwoven fabric or the like in which the resin fibers c are randomly entangled can also be used.

Then, the rod material 1A on which the base sheet 12 is wound is processed. That is, although not shown, the outer peripheral surface is polished by a centerless polishing machine. As shown in FIG. 2, in the reel seat mounting portion, the outer diameter is formed on a tapered surface L1 whose diameter gradually increases. This tapered surface L1 is referred to as a tapered mounting seat 11 for a reel seat.
On the other hand, on the rear end side of the tapered mounting seat 11 for the reel seat, a linear mounting seat 13 for grip mounting is formed which is maintained at the same outer diameter as the rear end outer diameter of the tapered mounting seat 11 for the reel seat. .

The dimensional relationship between the reel seat tapered mounting seat 11 and the grip mounting linear mounting seat 13 thus formed is, for example, as shown in FIG.
(1) Regarding small-diameter rod In the tapered mounting seat 11 for the reel seat, the rod tip side diameter B is 8.70 mm, the rod base side diameter A is 9.70 mm, the length Lb is 154 mm, and the taper is 6.49 / 1000. is there. Note that the Lb dimension presented hereinafter indicates the minimum length, and may be longer than that length.
(2) Medium diameter rod In the tapered mounting seat 11 for a reel seat, the rod tip side diameter B is 11.50 mm, the rod base side diameter A is 12.80 mm, the length Lb is 111 mm, and the taper is 11.71 / 1000. It is.
(3) Large Diameter Rod In the tapered mounting seat 11 for the reel seat, the rod tip side diameter B is 12.30 mm, the rod base side diameter A is 13.90 mm, the length Lb is 111 mm, and the taper is 14.41 / 1000. It is.
(4) In addition, the straight mounting seat 13 for grip mounting is manufactured without limit and without taper, but 1 mm / 1000 or less is sufficient.

The reel sheet 3 is externally fitted to the tapered mounting seat 11 for the reel sheet formed as described above, as shown by a two-dot chain line in FIG. The intermediate grip body 10, the rear grip body 5, and the original side tail ring body 7 are externally fitted and fixed to the grip mounting linear mounting seat 13.
In the case where the reel seat 3 is mounted on the tapered mounting seat 11 for the reel seat, the reel seat 3 had to be always mounted from the pole tip side having a small outer diameter in the related art. The grip body 5 and the like can be attached from the pole base side, and the degree of freedom of the assembling method is large.
Although not shown, a spacer which does not affect the rod rigidity may be inserted between the reel sheet 3 and the rod material 1A.

  In this manner, by tapering the reel seat mounting portion, when a jigging operation is performed to invite a fish, the bending of the rod is also observed in the reel seat mounting portion, and this portion is suppressed from stretching, and the angler is prevented from fishing. However, the feeling of discomfort is reduced, and the operational feeling is improved.

[Second embodiment]
In the second embodiment, a description will be given of the fact that the portion of the grip mounting linear mounting seat 13 formed on the rear end side of the tapered mounting seat 11 for the reel seat in the first embodiment is also formed in a tapered shape.
As shown in FIG. 7, a base sheet 12 made of prepreg is wound around a rod material 1A that forms the hand-side rod body 1. The pedestal sheet 12 has a trapezoidal shape, and one side 12A of the rod tip is cut so as to be inclined with respect to the axis, and the other side 12B of the rod base side is cut so as to be orthogonal to the axis. .
Such a pedestal sheet 12 is wound around the rod material 1A from the reel sheet attachment site to the rod base end. The number of windings is 2 to 5 plies, and the number of plies tends to increase as the rod diameter increases.

  Then, the rod material 1A on which the base sheet 12 is wound is processed. That is, the outer peripheral surface is polished by the centerless polishing machine. As shown in FIG. 6, over the entire length L from the reel seat mounting site to the rear grip body mounting site, the outer diameter is formed on a tapered surface whose diameter gradually increases. This tapered surface is referred to as a full-length tapered mounting seat 14.

  In the full length tapered mounting seat 14, as described in FIG. 9, the taper is 6.49 mm / 1000 for the small diameter rod, 11.71 mm / 1000 for the medium diameter rod, and 14.41 mm / 1000 for the large diameter rod. Although it is set to 1000, it is not limited to these tapers, and a taper up to 20 mm / 1000 can be adopted.

  As described above, since the taper is formed not only at the reel seat mounting portion but also at the rear grip mounting portion, the entire bending of the fishing rod is further improved, and the fishing operation is more preferable.

[Another embodiment]
(1) The fishing rod to be removed can be applied to a fishing rod having a reel sheet for mounting a spinning reel without the trigger 3C.
(2) The present invention is not limited to the jigging fishing rod, and may be applied to other fishing rods.

  INDUSTRIAL APPLICABILITY The present invention can be used mainly for a fishing rod or the like for jigging, and can construct a fishing rod which has good bends in a reel sheet portion and a grip portion at hand and gives a good fishing operation feeling.
