Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing rod, and more particularly, to a fishing rod made by winding a prepreg prepared by impregnating a synthetic resin drawn sheet of high-strength fibers in the direction in which the high-strength fibers are drawn.

Traditionally, this type of fishing rod has been formed into a tapered shape with a small rate of change in diameter, and the handle of the rod body has a
An inclusion of cotton or rubber was wrapped with tape to form a large-diameter grip that was easy to grip.

By the way, fishing rods are required to transmit the slight vibrations caused by the fish biting into the bait from the tip of the fishing rod to the hand, and transmit them sensitively to the hand holding the grip, but as mentioned above, conventional fishing rods are Since the inclusion is provided between the hand and the hand that grips the handle, the vibration that is transmitted to the hand of the rod body is damped by the inclusion, and the vibration is not transmitted to the hand as sharply. It was hot.

Therefore, the present inventor attempted to improve this type of fishing rod by integrally forming the rod body, which has a small diameter as a whole, and the grip portion, which has a considerably larger diameter than the rod body, with a prepreg via a tapered portion. That is, as shown in FIG. 2, a small diameter portion 51 having a small diameter change rate and a large diameter portion 52 having a considerably larger diameter than the small diameter portion 51 are connected to a tapered portion 53 having a large diameter change rate.
The prepreg 54 is wound in the direction of alignment of the high-strength fibers around the core metal 50 integrally formed through the core metal 50, and after wrapping cellophane tape (not shown) around the outside thereof, it is tied tightly and pressurized. The core bar 50 was then removed and the cellophane tape was peeled off.

In this way, the vibration of the tip (not shown) of the rod body 56 is directly transmitted to the grip portion 57 and transmitted to the hand, resulting in good sensitivity, but on the other hand, when used for a long period of time, the taper portion 55 However, there were drawbacks to poor durability, such as wrinkles and cracks in the circumferential direction.

As a result of research to find out the cause of this, it was found that in the fishing rod having the structure shown in FIG.
Distortion occurs in the tapered portion 55 in the winding directionb. Each high-strength fiber is forcibly bent in the length direction at both ends of the tapered portion 55, so that each high-strength fiber is bent due to its elasticity. In particular, the rod body 56 and the tapered portion 5
It was found that the wound prepreg (high-strength fiber) was deformed to float as shown in FIG. 3 at the boundary with 5, and as a result, a new strain was generated at this boundary. It was concluded that these strains are largely responsible for the decrease in strength of the tapered portion 55 and the occurrence of wrinkles and cracks.

Therefore, the present inventor believes that the strength of the tapered portion 55 can be improved by preventing the floating deformation of the high-strength fibers at the boundary described in b above and removing the resulting strain. At the same time, the wrinkles in the tapered portion 55, which are a phenomenon of destruction, are also caused because the wound prepreg (high-strength fiber) is lifted locally due to the bending stress applied to the tapered portion 55, and cracks also occur due to this. Focusing on the problems that occur in connection with this, we came up with the idea that by reinforcing the tapered portion 55 to prevent the high-strength fibers from floating, the strength of the tapered portion 55 can be increased and breakage can be prevented. .

Therefore, the object of the present invention is to integrally form the rod body and the grip part through a tapered part, and to wrap a reinforcing tape around the tapered part to prevent the high-strength fibers from floating. This allows for a structure that allows the vibration of the tip to be transmitted sensitively to the grip, while
Moreover, the strength of the tapered portion is increased and the durability is also improved.

Accordingly, the present invention provides a fishing rod in which a prepreg made by impregnating an aligned sheet of high-strength fibers with a synthetic resin is wound in the alignment direction of the high-strength fibers, and the rod body has a small rate of change in diameter. and a grip part are integrally formed on one side of the rod body through an enlarged diameter tapered part having a large rate of change in diameter, and at least the rod body side in which the rate of change in diameter is large in the tapered part. A reinforcing tape was wound around the base to prevent the high-strength fibers from floating.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The fishing rod shown in FIG. 1 is a fishing rod according to the present invention, in which a prepreg A made by impregnating a sheet of high-strength fibers with a synthetic resin is wound in the direction of the high-strength fibers, resulting in a rate of change in diameter. A rod body 1 with a small diameter and a grip portion 3 are integrally formed on one side of the rod body 1 via an enlarged diameter tapered portion 2 having a large rate of change in diameter.

Furthermore, in order to prevent the floating action of the high-strength fibers in the tapered part 2, the fishing rod configured as described above is further provided with a part of the tapered part 2 including the vicinity of the base on the side of the rod main body 1. Main body 1
The reinforcing tape 4 made of the high-strength fiber is wound spirally and tightly around the vicinity of the tapered portion 2 and on the outside of the portion between the tapered portion 2 and the grip portion 3.

The reinforcing tape 4 is wound in the manufacturing process after the prepreg A is wound around a core metal (not shown) and before the cellophane tape (not shown) is wound and heated. It is done to.

By doing so, even if the cellophane tape is peeled off after the heat forming, the tapered portion 2 is restrained by the reinforcing tape 4, so the high-strength fibers of the tapered portion 2 perform a floating action. Furthermore, even if the wound prepreg A (high-strength fiber) tries to perform a local floating action that causes wrinkles due to the bending stress acting on the tapered portion 2 during use, This floating action is reliably prevented by the reinforcing tape 4. As a result, the tapered portion 2
This increases the strength of the material, reliably prevents wrinkles and cracks, and improves durability.

In the above embodiment, the reinforcing tape 4 was wound from the vicinity of the tapered part 2 to the grip part 3 of the fishing rod body 1, but in view of reducing the weight of the fishing rod, etc. It may be wound only around the base of the main body 1.

Further, the reinforcing tape 4 is not limited to the same material as the prepreg A, and the winding of the reinforcing tape 4 during the manufacturing process may also be limited to before heat forming as in the above embodiment. do not have.

As described above, the present invention provides a fishing rod in which a prepreg made by impregnating a sheet of high-strength fibers with a synthetic resin is wound in the direction of the high-strength fibers. , a grip part is integrally formed on one side of the rod body through an enlarged diameter tapered part having a large rate of change in diameter, and at least a base part on the side of the rod body in which the rate of change in diameter is large in the tapered part. Because a reinforcing tape is wrapped around the area to prevent the high-strength fibers from floating, the slight vibrations of the tip can be transmitted to the grip part and transmitted to the hand, while the height of the tapered part is The strength fibers can be prevented from floating, and as a result, the strength of the tapered portion can be increased, wrinkles and cracks can be prevented, and durability can be improved.
