DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod which is formed by connecting a plurality of rods into a single rod.

[0002]

2. Description of the Related Art Some conventional fishing rods have a relatively long rod, which is generally referred to as a "one-piece rod", in which a plurality of rods are connected and integrated.

[0003] In this type of fishing rod, a plurality of cylindrical rod bodies made of fiber reinforced resin in which carbon fibers, glass fibers, and the like are aligned and impregnated with a synthetic resin are mutually connected through a core material called a spigot core. The fishing rod is connected so as to be in close contact with each other, and the rod body and the core material are bonded and fixed with an adhesive or the like to form a fishing rod as a whole. Since this type of fishing rod has a plurality of rod body parts physically bonded and fixed, it is superior in the strength of the connection part compared to the connection part between rod bodies such as ordinary parallel type and swing type, It is applied to various types of fishing rods.

[0004]

However, there is a limit to the length that can be manufactured as one rod body in terms of facilities. This is because a single rod having an excessively long length cannot be fully coped with in a series of manufacturing processes such as a firing process and a polishing operation of the rod, and the work process becomes complicated and lacks realism. . Therefore, in order to manufacture a rod having a relatively long length, the rod is divided into a plurality of rods, and the rods are connected to form a long rod (one-piece rod). It is.

[0005] Since there is a limit to the length that can be manufactured as a single rod body, the total length of a one-piece rod manufactured by connecting these rod bodies naturally depends on the number of rod bodies to be connected. Will happen. However, there is a great demand for a longer one-piece rod.

[0006] Even in the case of a one-piece rod, the strength of the connecting portion between the rod body and another rod body is weaker than that of the other parts, and further improvement in strength is required. Further, such a connecting portion is not preferable in appearance.

It is an object of the present invention to provide a one-piece rod having a sufficient length and excellent strength and appearance.

[0008]

A rod according to a first aspect of the present invention is a rod constituting a fishing rod used for fishing, and is connected to a core in a state where a core and a tip side of the core are inserted. A first rod body portion having a cylindrical shape, a second rod body portion connected to the core member at an interval from the first rod body portion with the rod base side of the core material inserted, and a first rod body portion. And an auxiliary portion disposed on the outer peripheral surface of the core between the second rod portion.

In this rod body, the first rod body part and the second rod body part are respectively connected to the core material with a space therebetween, and the distance is equal to the distance between the first rod body part and the second rod body part. The total length is longer than the sum of the lengths of the simple first rod portion and the second rod portion. A core material and an auxiliary part are arranged in this space, and the connection strength is ensured. Thus the first
By connecting the rod portion and the second rod portion, a long one-piece rod can be provided.

In addition, an auxiliary portion is provided to allow the first rod portion and the second
By treating the connecting portion with the rod portion at the same level, the connecting portion does not become excessively noticeable and a one-piece rod excellent in appearance is obtained.

A method according to a second aspect of the present invention is a method for manufacturing a rod constituting a fishing rod used for fishing, and includes the following steps. ◎ The first rod body part and the second rod part on the tip side and the rod base side of the core material, respectively.
A step of connecting the rod portion to each other at an interval. A step of winding a fiber reinforced resin around the core material between the first rod part and the second rod part. ◎ A step of firing the fiber reinforced resin to integrate the first rod body, the second rod body and the core.

In this method, each rod body separately prepared is connected via a core material at an interval (if necessary, the rod body and the core material are bonded with an adhesive or the like), and the distance between the rod bodies is adjusted. Each part is integrated by winding a fiber reinforced resin around the part. For this reason, a one-piece rod excellent in connection strength of each member and having a long length can be easily manufactured. In addition, since the fiber reinforced resin is newly wound around the space between the two rods, it is easy to make the two rods flush with the connecting part, and a one-piece rod having an excellent appearance can be easily manufactured.

A cylindrical rod grip 3 made of an elastic member such as wood or urethane rubber is arranged on the rod side of the former rod 1, and a reel (not shown) is detachably mounted on the tip side thereof. A front grip 5 made of the same wood or elastic material as the mountable reel sheet 4 and the rod base grip 3 is arranged and fixed. The inner circumference of the tip end of the former rod 1 is a fitting female part.

As will be described later, the rod body 2 is a member having a long overall length by connecting and integrating a plurality of cylindrical rod members. A male fitting portion is formed at the rod base end, and the male fitting portion is inserted into the female fitting portion of the original rod 1 and connected to the tip side of the original rod 1 in a so-called parallel manner.

As shown in FIG. 2, a part of the rod 2 is formed by connecting a plurality of cylindrical rods in order, and integrally fixing them. The number of rod portions to be used is arbitrary, and is configured using an arbitrary number of rod portions according to a required design length.
The configuration of the connecting portion of the rod body is as follows.

As shown in FIG. 2, a connecting portion of the rod body 2 includes a core member 12 and a first cylindrical rod member connected to the core member 12 with the tip end of the core member 12 inserted. A second rod body portion 11 connected to the core member 12 at an interval from the first rod body portion 10 in a state where the rod base side of the core member 12 is inserted;
An auxiliary part 13 is provided between the rod part 10 and the second rod part 11 on the outer peripheral surface of the core 12.

The first rod portion 10 and the second rod portion 11 are tapered cylindrical members made of prepreg in which carbon fiber or glass fiber is impregnated with a synthetic resin, like the original rod 1. Also,
The core member 12 is also a cylindrical body made of prepreg. The outer diameter of the core material 12 is the first at the tip side and the rod base side.
The inner diameter of the rod portion 10 matches the inner diameter of the second rod portion 11. The core material 12 is inserted halfway into the first rod body 10 and the second rod body 11 on the tip side and the rod base side, and the first rod body 10 and the second rod body 11 are inserted. Are connected at an interval without direct contact. Although this interval is an arbitrary setting item, it is approximately 50 to 200 mm. In addition, the 1st rod part 10, the 2nd rod part 11, and the core material 12 are each fixed with adhesives etc. as needed.

The auxiliary section 13 is also a section formed of a prepreg. The first rod body 10 and the second rod body 11 are arranged on the peripheral surface of the core member 12 so as to fill the axial space. The outer peripheral surfaces of the first rod portion 10, the second rod portion 11, and the auxiliary portion 13 are surface-processed so as to be flush.

The rod 2 is manufactured as follows. First, the first rod portion 10 and the second rod portion 11 are manufactured according to a general rod manufacturing method. Specifically, a prepreg impregnated with a synthetic resin is wound around a mandrel tapered mandrel called a mandrel while pulling carbon fiber or glass fiber in one direction and applying pressure, and firing this in a furnace. Then, the mandrel is pulled out, and the first rod body 10 and the second rod body 11 are manufactured. Meanwhile,
Similarly, a core material 12 having a predetermined outer diameter is separately manufactured.

As shown in FIG. 3A, the first rod body 10 and the second rod body 11 are connected to the tip side and the rod base side of the core member 12 with a space therebetween. I do. These are fixed with an adhesive or the like as necessary.

Subsequently, as shown in FIG. 3B, another prepreg is wound around the peripheral surface of the core member 12 between the first rod body 10 and the second rod body 11. This prepreg is preferably a prepreg processed into a tape shape, and it is preferable that the carbon fibers and glass fibers are arranged in the circumferential direction of the rod body in view of working efficiency and strength after production.

Thereafter, the wound fiber-reinforced resin is fired to form an auxiliary part 13 integrated with the first rod part 10, the second rod part 11, and the core material 12. Then, the surface is polished to make the surface uniform, a necessary paint or the like is applied, and the surface is processed to manufacture the rod body 2.
