Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing rod that connects a handle rod made of a membranous body formed by aligning or weaving fiber threads such as carbon fibers and glass fibers.

Recently, fishing rods made of carbon fibers and glass fibers are commonly used, and efforts are being made to reduce their weight and improve their performance. Among the features of this fishing rod, it is important to make each handle rod thinner so that it is easier to handle and has less air resistance and better wind deflection, especially when fishing long distances. Therefore, improvements are being made in the direction of increasing the diameter of each handle rod. As each handle rod becomes smaller in diameter, the connection part of each handle rod becomes the so-called "
It has come to have a noticeable effect on the "tone". That is,
For a fishing rod, it is best to have a diameter that gradually increases in a straight line from the tip to the base, like a natural bone, as it gives a natural flex as a whole. In addition, the diameter of the protruding portion of each handle rod is different from that of other parts, and the rigidity is also extremely increased, so as the diameter of each handle rod is reduced, this has a significant negative effect. More specifically, in the juxtaposition shown in No. 111A, for the handle rod a that is the upper rod, the handle rod that is the lower rod is first interpolated with the handle ub for the handle rod a that has a diameter R1. In order to
1, and the diameter increases from the large diameter tip to the rear end, so even if you look at it partially, there is a natural diameter increase between the handle a and the handle. I can't.

In addition, in the so-called "spigot joint" shown in Fig. 1, in order to make the increase in the diameter of each handle rod a natural shape, connecting piece 0 is used to connect handle rod a and handle rod. Although an internal tube structure is adopted, due to the strength of the connecting part of both handle rods a and b, it is necessary to insert the connecting piece C into both handle rods a and b' for a relatively long time. , the external shape is a fishing rod with a natural diameter increase, and the stiffness increases extremely in a relatively long area due to the interpolation of the keel and connecting piece C, so it has a very good "condition J". No fishing rod was asked for.

The present inventor has developed fishing rods using carbon fibers and glass fibers by making the diameter smaller while improving the overall "condition" of the fishing rod.
As a result, they completed a fishing rod that overcomes the drawbacks of the conventional bamboo fishing rod.The first invention was a fishing rod consisting only of a membrane-like body formed by aligning or weaving fiber threads. In a fishing rod that is connected like a book handle, only the tip of the handle that is the lower rod that is inserted and connected to the upper rod at the connection part of each handle is attached to the handle of the upper rod. The diameter is larger than the diameter of the rear end of the rod, and when the overall shape of each rod is connected from the tip to the base rod, excluding the connection part,
It is characterized in that the diameter of the rod continuously increases in force d in a straight line. The second invention provides a method for manufacturing a handle rod for constructing the fishing rod of the first invention, in which the first core metal and the first core metal are attached to a tapered first core metal whose diameter increases linearly. A second core bar having a reverse taper is connected, and a membrane body formed by pulling, aligning or weaving fiber threads is impregnated with a thermosetting synthetic resin and wound around both core bars. It is characterized in that fibers formed into a band shape corresponding to the connection positions of both core metals are wound in a spiral shape, and then heated and hardened.

A more detailed explanation will be given below with reference to FIGS. 2 and 3 showing an example of the implementation of the present invention.

Figure 2 shows the connection part (1) in a part of a fishing rod in which the handle rods that become larger in diameter from the tip to the base rod are connected, and the rear end of the handle rod (2) which is the upper rod. The part (3) was inserted into the tip part (5) of the handle rod (4), which is the lower rod.

Each handle rod +2+ (4) is composed of a membrane-like body formed by aligning or weaving carbon fibers, for example, similar to a handle rod made of ordinary carbon fibers, and in order to achieve e-weighting and a small diameter, - The thickness of the handle rods (2) and (4) is preferably 1°. The diameter increases linearly from the base rod (not shown) to the base rod (not shown).

Further, the handle rod (4) was formed so that the diameter of the rear end of the handle rod (2) was extended, excluding the connecting portion (1), so that the diameter increased linearly. Therefore, the handle rod (2+i4) connects to the connection part (1
) has an outer circumferential surface that extends in a straight line. This also applies to the connections in other handle rods.

As a result, the entire fishing rod connected from the tip to the base rod, excluding the connecting part, increases in diameter in a straight line, taking on a shape similar to that of natural bamboo.

On the other hand, in the connection part (1), only the tip (5) of the handle rod (4) into which the handle rod (2) is inserted has a larger diameter than the rear end (4) of the handle rod (2). However, the length of the large diameter tip (5) was made as short as possible in consideration of connection strength.

This increased the diameter of the connecting portion (1, .) and inserted the rear end (3) of the handle rod (2), increasing the rigidity and minimizing the negative impact on the "tune". At this time, handle rod (4)
It is necessary that the large and rear portion formed at the tip (5) of the handle rod (4) be formed of a membrane-like body that is continuous with the other parts of the handle rod (4) and is aligned or woven. That is, as a configuration in which only the tip end (5) of the handle rod (4) has a large diameter,
As shown in Figure 4, the tip (5) of the handle rod (4) is formed with a separate large diameter member (6), which is inserted and connected to the handle rod (4) and fixed with adhesive. has a similar configuration, but in this case, in order to firmly connect the separate member (6) and the handle rod (4), a considerable length is required to insert the handle rod (4) into the separate member (6). ) would have to be interpolated, which would result in a significant increase in stiffness in this connection (1), making it impossible to achieve the object of the invention.

In the illustrated embodiment, the handle rod (4) is integrally formed with a membrane-like body formed by aligning or weaving fibers from the tip (5), which is the connecting portion (1), to the rear end by a manufacturing method described later. was formed. Therefore, the connection part (1) of the handle rod (2) (4)
), the thickness of both handles (2+ (41) tends to increase the rigidity, but in the connection (1), the rear end (3) of the handle (2) The rear end (3) of the handle rod (2) is inserted into the tip (5) of the handle rod (4) when it is bent as a fishing rod.
), which contributes to reducing the increase in stiffness.

The configuration of the above connection part (11) was the same for the connection parts of each other handle rod.

In the embodiment configured in this manner, the diameter of the entire fishing rod increases linearly except for the connecting portion (1), and the configuration of the connecting portion (11) makes it possible to increase the rigidity at the knee portion. Because it has fewer particles, the fishing rod is in good condition, just like natural bamboo.

Next, an example of a method for manufacturing a handle rod having the above-mentioned structure will be described. As shown in No. 311A, a tapered first core bar (7) whose diameter increases linearly is attached to the first core bar (7). ) and the second core bar (8) having a reverse taper, and the connecting rod (9) with the first core bar (8).
A core device is used which is removably connected to the tip of the core metal (7). To this, the fifth [align the carbon fibers as shown in JA,
A film-like body (a) impregnated with an uncured thermosetting synthetic resin such as ebochishi resin or urea resin is formed into a fan shape and is normally rolled up in a regular manner.

The film-like body (10) wound around the core metal device in this way is
As shown in Figure B, since the connection between the first core metal (7) and the second core metal (8) does not come into close contact with both core metals (71 (8)), if it is formed as a handle rod (4). As shown in Fig. 3, carbon fiber cloth is spirally wrapped with reinforcing fibers 0υ in the shape of a belt to reinforce the tip end (5) which becomes the connection part (1).At this time, the first core The part of the membrane-like body (9) wound at the position corresponding to the connection part between the gold (7) and the second core metal (8) is exposed to a large load when used as the connection m (11) of the fishing rod. Since this easily occurs, cellophane tape containing 20 to 40% water is used to reinforce it with reinforcing fibers (Ill) and to evenly and thoroughly impregnate the disseminated synthetic resin.
It is preferable to further tighten the winding spirally at step 21.

Next, after heating the film-like body (1ω) together with the core metal device to heat and harden the synthetic resin, the first core metal (7) and the second core metal (
8) are pulled out in the respective directions to obtain a handle structure with a large diameter tip, and further finished by polishing and painting to obtain a finished product.

Other handle rods are manufactured in the same manner, but at this time, the first core metal (
Regarding the diameter of the tip end side of the handle rod (4) formed by the taper of 7), as shown in the second figure, the diameter increases linearly except for the part (1). It is obvious that

According to the first aspect of the present invention, at the connection part of each handle rod, only the tip of the handle rod, which is the upper rod, which is inserted and connected to the handle rod, which is the upper rod, is connected to the upper rod. A region whose diameter is larger than the diameter of the rear end of the handle rod, and where the rigidity of the connecting portion increases when the connecting portion is integrally formed only with a membrane-like body formed by aligning or weaving fiber threads and is connected accordingly. reduce as much as possible,
In addition, when the rear end of the handle of the upper rod is inserted and tied to the tip of the upper rod and bent, the rear end of the handle of the upper rod slides within the handle of the upper rod and the tip of the rod. This reduces the increase in rigidity of the connection part by allowing the
Since the overall shape is such that the diameter increases linearly, a fishing rod with good "condition" like natural bamboo is provided.

According to the second invention, a tapered first core bar whose diameter increases linearly is connected to a second core bar having an inverted taper, and fiber threads are aligned or woven into this. The membrane material is impregnated with thermosetting synthetic resin and wound around both core metals.
It is advantageous in that it can be easily manufactured by spirally winding fibers formed into belts corresponding to the connecting positions of both core metals of the membrane-like body, and then heating and curing.
