Description

TECHNICAL FIELD The present invention relates to a fishing rod, more specifically, a prepreg of a high-strength fiber in which a synthetic resin is impregnated on a cored bar that expands in a tapered shape from a distal end portion toward a proximal end portion. The present invention relates to a fishing rod in which a grip portion having a diameter larger than the diameter of the base end portion is provided at the base end portion of a hollow rod body to be wound and formed.

(Prior Art) Generally, in this type of fishing rod, when the grip has a diameter larger than the outer diameter of the rod body on the base end side, a padding such as paper or cotton is threaded on the outer periphery of the base end of the rod body. It is wrapped with a tape-like body such as tape and raised in a taper shape so that it can be easily gripped.

However, it takes a lot of work to form the grip,
Not only is workability extremely poor, but because the structure is such that paper, cotton, and other fillings are wrapped with a string-like body, there are large variations in the outer shape between products, and the strength with respect to the diameter is small, and the weight is large. There was a problem.

Therefore, in order to solve the above-mentioned problems, Japanese Patent Application No. 58-1
According to No. 18136, the base end portion of the rod body is extended with a grip portion that expands at a rate of change larger than the rate of change of the diameter of the rod body, and the grip portion is formed integrally with the rod body. We have proposed a product that can be formed into a thickness that makes it easy to hold, has good workability, has high strength, and is lightweight.

However, when gripping the grip portion and performing fishing, since the grip portion has a taper that reduces in diameter toward the tip side, the grip body has a rod main body with respect to the hand gripping the grip portion. An action force in the backward direction is generated, and as a result, the action part causes the grip part to slide with respect to the grip hand, causing the rear part of the rod body to move backwards as if protruding to the rear of the hand. However, there is a problem in that the grip of the grip portion is poor.

(Object of the Invention) An object of the present invention is, when gripping a grip, a forward taper-shaped first grip and a reverse taper-shaped second grip that expand at a rate of change greater than the rate of change of the diameter of the rod body. And the rod body can be simultaneously gripped, the rod body can be prevented from moving in the front-rear direction with respect to the gripping hand, and at the boundary portion between the first grip portion and the rod body where stress is easily concentrated. It is possible to reduce wrinkles, to avoid a decrease in strength at the boundary between the first grip portion and the rod body due to the wrinkles, and to further reduce the weight of the fishing rod provided with the first and second grip portions, and to grasp these grips. In addition to being able to increase the strength of the part against external damage, and being able to sensitively detect a hit with the hand holding the grip, when used as a hand-held rod of a swing-out rod, an intermediate rod and an inner rod to be stored inside the hand-held rod. Storing the tip over the rear end of the second grip Another object of the present invention is to provide a fishing rod which is capable of preventing the intermediate rod and the tips from colliding with and damaging the inner surface of the grip portion during storage.

(Structure of the Invention) The structure of the present invention comprises a rod main body formed by winding a prepreg of high-strength fiber impregnated with a synthetic resin into a tapered hollow, and a grip portion provided on the rear side of the rod main body. In the gripping area, the grip portion has a substantially tapered outer surface that expands from the front to the rear at a rate of change greater than the rate of change of the diameter of the rod body, and the tapered outer surface and the substantially reverse taper outer surface. A hollow forward taper formed integrally with the rod body by a prepreg separate from the prepreg of the rod body, which is made of high-strength fiber impregnated with a synthetic resin, wound around the front half of the core material A first grip portion and a prepreg of high-strength fiber wound around the latter half of the core material and impregnated with a synthetic resin, which is separate from the prepreg of the rod body, is formed continuously and integrally with the first grip portion. Hollow reverse taper shaped second grip And the inner surface of the core member has an inner diameter that does not protrude inward from the inner surface of the rod body.

(Example) Hereinafter, the Example of this invention is described based on drawing.

The present invention is basically a cored bar (1) that expands in diameter in a taper shape from a front end toward a rear end (a) and a front end (b) on the front side.
A prepreg for a rod body (2) of high-strength fiber impregnated with a synthetic resin is wound on the front side of the base end of the core metal (1), and the base end (b) of the core metal (1) is wound. ) On the rear side, a first molding surface (41) of the first grip portion (3) having a substantially tapered outer surface (31) that expands at a rate of change greater than the rate of change of the diameter of the rod body (2); A hollow core in which the tapered outer surface (31) of the first grip portion (3) and the second molding surface (42) of the second grip portion (5) having a substantially reverse tapered outer surface (51) are arranged in front and rear. A material (4) is removably attached to the first molding surface (41) of the core material (4), and a prepreg of high-strength fiber impregnated with a synthetic resin, which is separate from the rod body prepreg, is provided at the front end thereof. The second molding surface is wound in a continuous state so that the side overlaps with the rear outer peripheral surface of the rod body prepreg wound around the core metal (1). 42), a prepreg of high-strength fiber impregnated with a synthetic resin, which is separate from the prepreg of the rod body, is continuously wound so that the front end side of the prepreg is superposed on the rear outer peripheral surface of the first grip prepreg. After that, each prepreg is pressure-fired to integrally form a grip portion on the rear side of the rod body (2).

This grip portion has a substantially tapered outer surface (31) in the gripping area, which has a substantially tapered outer surface (31) that expands from the front to the rear at a rate of change larger than the rate of change of the diameter of the rod body (2). 2) a hollow forward-tapered first grip portion (3) which is continuously formed integrally with the second grip portion (2), and a substantially reverse taper outer surface (51) whose diameter decreases rearward from the rear end portion of the first grip portion (3). ) With the prepreg, the first grip portion (3)
And a hollow reverse taper-shaped second grip portion (5) which is continuously and integrally formed with the first and second grip portions (3).
The inner surface of the core member (4) provided inside (5) has an inner diameter that does not project inward from the inner surface of the rod body (2).

The core metal (1) shown in FIG. 1 has a molding portion (11) of the hollow rod main body (2) extending from the tip portion to the base portion (b).
And a support portion (12) of the core material (4) extending from the base end portion (b) to the rear end portion (a) are integrally and continuously formed, and the molding portion (11) is the tip end. From the portion toward the base end portion (b) is formed so as to have a small taper outer surface (c) that expands at a taper angle with a small rate of change in diameter, and the support portion (12) is formed by the molding portion ( The diameter is increased with a slight taper from the base end portion (b) to the rear end portion (a) of 11) to facilitate the drawing after the entire molding process is completed.

In addition, the core material (4) is a support portion (1) of the core metal (1).
2) has a removable inner surface and a molding surface (41) having the tapered outer surface (31) on the front half and the rear half of the outer surface of the core material (4) and the reverse taper outer surface. The molding surface (42) having (51) is continuously formed.

The core material (4) has good peelability from the core metal (1) as a material to be used, and the winding pressure of the first and second grip portions (3) and (5). The core metal (1) and the core material (4) after the molding process for the core metal (1) and the core material (4) have only the core metal (1) extracted as described below. Then, as shown in FIG. 2, when the core material (4) is left as it is, a material having a small specific gravity capable of retaining lightness, such as cork material, synthetic resin, or light alloy is used. In addition to the above-mentioned performances, the cork material has good machinability, and can be scraped and removed without leaving after the step of extracting the core metal (1).

Next, the rod main body (2), the first grip portion (3) and the second grip portion (5) are, as each of the prepregs, an aligned sheet or woven sheet of high strength fibers such as carbon fibers. Using the one impregnated with the synthetic resin, the prepreg for the rod body (2) is wound around the front side of the base end (b) of the core metal (1), and the rear end of the base end (b) is used. The core material (4) is attached to the side, and the front side of the core material (4) is
The prepreg for the first grip portion (3) is wound so that a part of the prepreg overlaps the rod body (2), and the second grip portion (5) is provided behind the core material (4). The prepreg for use is wound so that a part of the prepreg overlaps the first grip portion (3) in a series.

Then, a wide wrinkle-preventing tape (not shown) is wound around the rod body (2) and the first and second grips (3) and (5) wound as described above to apply pressure. Therefore, the tape outer surface (31) is expanded in the first grip portion (3) at a rate of change larger than the rate of change in the diameter of the rod body (2), and the second grip portion (3) is also used. In the grip (5),
The inverse tapered outer surface (51) having an inverse taper larger than the taper can be formed on the tapered external surface (31). By the way, the wide tape can prevent the generation of wrinkles at the boundaries between the rod body (2) and the first and second grips (3) and (5).

Further, a narrow tape (6) is spirally wound around the first and second grips (3) and (5) as shown in FIG.
A non-slip means composed of spiral protrusions is provided, and the narrow tape (6) also has a reinforcing function by using a prepreg in which high-strength fibers are aligned in a narrow width and impregnated with a synthetic resin. It can be given together.

Further, as the non-slip means, the narrow tape (6) is used.
In addition to the above means, although not shown, any circumferential groove,
It goes without saying that it can be formed by protrusions or a large number of irregularities.

Further, in FIG. 2, (7) is a butt plug.

Then, as described above, the core metal (1) for molding the rod main body (2) is formed by leaving the core material (4) in the first and second grips (3) and (5). Since the prepreg is made of high-strength fiber, it is possible to integrally form the rod main body (2) and the first and second grips (3) and (5) at the same time. Also, the second grips (3) and (5) can be easily formed to have a desired thickness so that they can be easily formed with good workability as a whole, and moreover, from the little finger to the thumb of the hand for fishing. From the rear end surface of the second grip portion (5), through the reverse taper outer surface (51), to the first
By arranging and gripping the taper outer surface (31) of the grip portion (3) over the rear side, the taper outer surface (31) gripped by the thumb side of the hand is gripped by the hand and the rod body ( Although the action force in the direction of moving the rod 2) is generated, the action in the direction of moving the rod main body (2) forward by the gripping force of the hand at the reverse taper outer surface (51 on the little finger side of the hand is held. A force is generated and acts as if the post-operation force is canceled.

Therefore, at the fixed position of the hand that straddles the first and second hand grips (3) and (5), there is no fear of the rod body (2) sliding and the gripping force is not increased. Both can be easily held and the gripping property with respect to the rod body (2) can be improved.

Further, the reverse taper outer surface (51), which is originally gripped on the little finger side having a smaller gripping force than the thumb side of the hand, has a larger rate of change in diameter than the taper outer surface (31). Even if the gripping force is significantly smaller than the gripping force on the thumb side, the action acting force is reduced to the taper outer surface (3
It is possible to counter the force for post-operation in 1).

On the other hand, since the prepreg forming the first and second grips (3) and (5) is wound continuously with the rod body forming prepreg, in other words, the first and second grips. Since the parts (3) and (5) are continuous with the rod body (2), the conductivity of the fish hit transmitted to the rod body (2) can be improved, and the hit with the hand holding the grip It can be perceived sensitively.

Furthermore, since the rod main body (2) is not present inside the core material (4), the core material (4) can be easily removed by cutting or the like. ) Is removed, the core material (4) is not present inside the grip portion, so that the conductivity of the hit can be further improved and the hit can be sensed more sensitively. Since there is no core material, the weight can be reduced.

In addition, since the first and second grips (3) and (5) are formed of prepreg, the first and second grips (3) and (5) can be increased in external damage strength and damaged. Further, since the prepreg is wound around the core material (4) to form the grip portion, it can be easily formed even when the first and second grip portions are concentric with the rod body. .

In addition, among the above-mentioned materials used for the core material (4), the cork material is an inner layer of the cork skin, and the prepregs for the first and second grips (3) and (5) are used. Winding pressure,
Also, it has strength and heat resistance against the molding temperature of the synthetic resin impregnated into the prepreg. Therefore, it can withstand the winding and heat molding of these prepregs without any trouble, and the cork material is light and elastic. Since it has the above, it is possible to suppress an increase in the entire weight to a minimum even if the device is used while being left between the first and second grips (3) and (5).

Further, especially in the first grip portion (3) which expands the diameter with a large rate of change in diameter with respect to the rod body (2), a prepreg separate from the prepreg of the rod body (2) has a core body (4). Since it is wound around the substantially tapered outer surface of the rod body and is continuously formed integrally with the rod body (2), wrinkles are formed at the boundary between the first grip portion (3) and the rod body (2) where stress is likely to concentrate. It is possible to reduce the amount, and it is possible to avoid a decrease in strength at the boundary between the first grip portion (3) and the rod body (2) due to the wrinkles.

Further, the inner surface of the core member (4) provided inside the first and second grip portions (3) and (5) has an inner diameter that does not protrude inward from the inner inner surface of the rod body (2). As a result, when used as a hand-held rod of the swing-out rod, the intermediate rod and the tip of the hand-held rod can be stowed without resistance over the rear end portion of the second grip portion (5). Yes, even if it is stored repeatedly, it is prevented that the intermediate rod and the tip collide with the inner surface of the core material (4) and the core material (4) is scraped, or the intermediate rod and the tip are damaged. You can do it.

Although not shown, the connecting portions of the first and second grip portions (3) and (5) are arranged so that the second grip portion (5) is inside and the first grip portion (3) is outside. It can also be configured to be connected in layers.

(Effects of the Invention) As described above, according to the present invention, the grip portion provided on the rear side of the rod body has, in its gripping region, a forward tapered first grip portion that is continuous with the rod body and a continuous first grip portion. Reverse tapered second
Since the grip portion is provided, when gripping the grip portion, the first and second grip portions can always be gripped at the same time, and therefore, the rod body can be held against the hand holding the grip portion. Can be prevented from moving backward and forward,
The grip of the rod body can be improved.

In addition, the diameter of the rod main body is increased at a large rate of change in diameter. Particularly, in the first grip portion, a prepreg separate from the prepreg of the rod main body is wound around the taper outer surface of the core material to form a rod main body. Since it is formed continuously and integrally, wrinkles at the boundary portion between the first grip portion and the rod body where stress is likely to be concentrated can be reduced, and this wrinkle reduces the strength at the boundary portion between the first grip portion and the rod body. It can be avoided.

Further, the first grip portion is continuous with the rear side of the rod body, the second grip portion is continuous with the first grip portion, and the rod body is interposed inside the first and second grip portions. Because there is no
It is possible to form a fishing rod with a first taper-shaped first grip portion and a second taper-shaped reverse grip portion in a lightweight manner. Further, by using a prepreg, the first grip portion is continuously connected to the rod body. Since the second grip portion is integrally and continuously formed with the first grip portion, conductivity to the first and second grip portions for hitting the fish can be improved and the hand holding the grip portion can be improved. The hit can be sensed sensitively, and the strength of the first and second grips against external damage can be increased, and damage can be made less easily.

In addition, since the inner surface of the core material around which the prepregs of the first and second grip portions are wound has an inner diameter that does not project inward from the inner surface of the inner pole body, the core material can be used as a hand-held rod of a swing rod. When used, the intermediate rod and the tip that are put inside the hand rod can be placed without resistance over the rear end portion of the second grip portion, and even if they are repeatedly put, the intermediate rod and the tip can be put together. Can be prevented from colliding with the inner surface of the grip and being damaged.
