Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement in a method for forming a space recessed in the grip of a fishing rod and used for storing small items.

<Conventional technology and its problems> Conventionally, prepreg is first wound around a tapered, substantially cylindrical rod-forming mandrel, and a tightening means such as a tightening tape is further attached to the surface of the prepreg to wind the prepreg. While keeping the turning state constant, the mandrel is placed in a firing furnace to be fired and hardened, and after curing, the mandrel is removed and the tightening means of the tape fat is removed to form a rod rod.

If spiral or other cracks are formed on the surface of the rod rod due to the use of the above-mentioned tape, the surface is polished by sanding.

Next, an annular body having a desired outer diameter is fitted and fixed to the front surface of the grip part located at the grip side end of the rod, and the entire circumferential surface of the grip part is surrounded by the outer periphery of this annular body. (Utility Model Publication No. 56-50769), the inner diameter of the tip side is approximately the same as the outer diameter of the rod rod, and the inner diameter of the proximal side is larger than the outer circumference of the rod rod. An integrally molded hollow cylinder having a diameter is fixed to the rod rod by fitting and fixing its tip to the tip of the gripping portion, thereby forming a space between the two (Japanese Utility Model Publication No. 58-100568). ing.

However, in all of these cases, it is necessary to separately form the TR-shaped body and the hollow tube, or only the hollow tube, and to fix this to the grip portion of the rod.

For this reason, an additional process is required that is different from the process of forming the rod rod, making the process management and material management complicated.In addition, since the separately molded items are connected, the fish confidence required for the fishing rod is increased. There is a problem where the performance deteriorates when the (hit) is sensed by the grip) part.

<Problems to be Solved by the Invention> The problems to be solved by the present invention are as follows: The problem to be solved by the present invention is that the process for forming the rod rod can be carried out in the same series of steps as molding the rod rod, without separately preparing the members constituting the gripping part. The purpose is to integrally form a grip portion having an inner space on the rod rod at the same time as molding.

<Rounding means to solve the problem> The technical means required by the present invention to solve the above problem is to form the main rod by continuously wrapping prepreg around the outer circumferential surface of the mandrel for forming the main rod. A space-forming mandrel is fitted and set on the outer circumferential surface of the grip portion of the forming layer, and prepreg is continuously wound around the outer circumferential surface of the space-forming mandrel from the outer circumferential surface of the forming layer. The prepreg is tightened and fixed to the outer periphery of both the mandrels by an appropriate tightening means, and after the forming layer of the main rod is baked and hardened, the tightening means is removed and both mandrels are pulled out.

<Operation> A space forming mandrel is fitted and set on the outer circumferential surface of the grip portion of the main rod rod forming layer, and prepreg is continuously wound around the outer circumferential surface of the space forming mandrel from the outer circumferential surface of the above forming layer. By tightening and fixing both prepregs to the outer circumferences of both mandrels using an appropriate tightening means and baking and hardening the forming layer of the main rod rod, the prepregs harden in a shape along the outer circumferential surfaces of both mandrels, and form the main rod rod. and a gripping portion are simultaneously formed, and the joint portions of the two are fused and integrated.

Next, when both the mandrels are removed, a mandrel-shaped space is formed between the gripping part and the circumferential surface of the main rod, and
A substantially donut-shaped opening is formed at the end on the grip portion side.

<Example> An embodiment of the present invention will be described based on the drawings.

In the present invention, first, a prepreg (3) is continuously wound around the outer peripheral surface of a cylindrical main rod rod forming mandrel (1) having a taper that gradually becomes smaller in diameter toward the tip.
, ) is formed.

Prepreg (3) is a conventionally well-known product in which a woven fabric or a stretched sheet made of carbon fibers, glass fibers, or a mixture thereof is dipped in a thermosetting resin solution and then dried to a semi-dry state. Cut into a specified shape and use.

Next, a hollow space forming mandrel (2) is fitted and set on the outer peripheral surface of the grip portion (200) located at the grip side end of the forming layer (a) (Fig. 1). , the prepreg (3) is continuously wound around the outer circumference of this mandrel (2) from the outer circumferential surface of the forming layer (lL,) to form a main rod forming layer (a,) and a gripping part forming layer (b,). A fishing rod body forming layer (A, ) consisting of the following is formed (FIG. 2).

The space forming mandrel (2) is made of metal or the like as in the past, and is shaped into a cylindrical shape with a desired outer diameter on the proximal side, and a substantially truncated conical shape with a taper such that the outer diameter gradually decreases on the tip side. At the same time, the center portion of the diameter is formed into a hollow shape extending in the length direction and having an inner diameter that is approximately the same as the outer diameter of the grip portion (200) of the main rod forming layer (a).

A tightening tape (4) is continuously wrapped around the outer circumferential surface of such a fishing rod body forming layer (Figure 3) as a tightening means (Fig. 3), and then baked and hardened.
4), and remove the spiral tightening marks by sanding, polishing this outer peripheral surface and attaching the grip part (,00) to the grip part (,00) of the main rod (a,).
b) A fishing rod body (A,) is formed.

Finally, remove both mandrels (IO2) attached to the fishing rod body (Figure 4).The step of removing both mandrels (IO2) is to remove the tape (4).
- It can also be provided immediately before or after the release stage.

In this way, the mandrel (2)-shaped gripping portion ~) is provided between the outer periphery of the hollow main rod (-,), and the gripping portion (b) and the main rod (!L,) A space (100) in the shape of the mandrel (2) is formed directly on the outer periphery, and a donut-shaped opening (300) is formed at the proximal end.

The joint length between the grip part (b) and the main rod (a,) (400
) is set appropriately in consideration of conditions such as the length and weight of the main rod (&, ). The longer this joint length (400) is, the more firmly the grip part (a) is fixed to the main rod (a,).

At this time, it is also possible to increase the thickness of the prepreg (3) itself to an appropriate size if necessary.

As shown in FIG. 6, the M (5) that covers the opening (300) is covered by screwing or the like on the proximal end of the fishing rod grip (b) thus formed. Thereby, small items can be placed in the space (100) and carried.

In addition, as the tightening means for the prepreg (3), the fishing rod body forming layer (A,) at the stage where the prepreg (3) is wound is attached to a pair of upper and lower layers, which have been recessed in the shape of the forming layer (A,) in advance. The fishing rod body (mu 2) may be fitted and placed in the recessed portion of the lower mold of the mold, and the upper mold may be placed and bonded thereto, and the fishing rod body (mu 2) is sandwiched and crimped between the upper and lower molds. In this case, the gripping part (100) having the space (100) inside is made by heating and curing it in the above-mentioned state, removing the upper and lower molds after curing, and pulling out both the mandrels (1) and (2). b) A fishing rod body (mu0) is formed around the fishing rod.

By using this tightening means, the sanding step can be omitted after baking and hardening.

In addition, the fishing rod body forming layer (mu,) can be prepared by rolling the air layer immediately between the bulipreg (3), the space forming mandrel (2), and the main rod forming layer (-) by removing the air layer between the outer periphery. The tightening means can be tightened more reliably, and bubbles can be prevented from forming on the surface after baking and hardening.

<Effects of the Invention> Since the present invention is configured as described above, it has the following effects.

■ It is possible to form the grip part with a space between it and the outer circumferential surface of the rod rod integrally with the outer periphery of the rod rod at the same time as molding the rod rod using the same series of steps as conventional molding of rod rods. be.

Therefore, there is no need for complicated schedule management and material management as in the past.

- Since the grip part and the rod are integrally formed, the strength and durability against external pressure at the boundary between the two is increased, unlike the conventional method in which they are formed separately and fixed together.

Moreover, since the rod and the grip are integrated, the sensitivity of the fish is also good.

Therefore, the intended purpose can be achieved.
