Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of manufacturing a fishing rod for cast fishing.

Prior Art In order to stably and reliably grip the fishing rod with the dominant hand, it has been proposed in Japanese Utility Model Application Publication No. 52-104894 and the like to provide a handle formed in a shape that is easy to grip at the end of the fishing rod. This is known from Japanese Utility Model Application Publication No. 56-37873, etc., but the current situation is that the rod body and the grip handle made of different materials are combined, so the manufacturing of the rod body and the grip handle are difficult. The manufacturing process has to be carried out separately, which makes the manufacturing process extremely complicated, and the fishing rod itself has poor sensitivity to fish, and the handle may come off due to moisture or dryness during use, or the rod may become damaged. There are defects that increase the weight of the product.

Problems to be Solved by the Invention In view of these current circumstances, the present invention simplifies the manufacturing of the throwing rod by integrally forming a handle portion with an easy-to-grip shape at the same time as manufacturing the rod body, and improves the performance of the throwing rod itself. The purpose is to encourage people.

Means for Solving the Problems As a means for achieving the above-mentioned object, the present invention provides prepreg for rod formation, in which the rear edge is formed obliquely on a core metal whose rear end portion is smoothly bulged. After wrapping the core metal so that the side edge is located in front of the bulge, the front edge is diagonally shaped from the rear part of the rod-forming prepreg-wrapped part to the bulge of the core metal. The gist of this method is to wrap the grip handle forming prepregs formed on the handle, then tape their outer circumferential surfaces, and then carry out heat curing treatment, core removal, and tape peeling in the usual manner.

Embodiment To explain the details of the embodiment of the present invention with reference to the drawings, a core metal 2 is formed with a tapered shape and a bulge 1 that gradually increases the diameter of the rear end and continues smoothly. A rod-forming prepreg 3 having an oblique shape is wound so that the winding start end of the rear side edge is positioned in front of the bulged portion 1.

Next, a grip handle forming prepreg 4 having an oblique front edge is partially polymerized from the rear side of the core metal wrapping portion of the rod forming prepreg 3 to the bulging portion 1 of the core metal 2. Wrap it as shown.

The rod-forming prepreg 3 and the grip handle-forming prepreg 4 wound around the core metal 2 in this way are wrapped around the outer periphery of the tape in a partially polymerized manner and bound together, and then subjected to the same heat curing treatment as in the past. After that, the tape is decentered and the tape is peeled off to form a grip handle having a thin diameter part 7 between the smooth thick large diameter part 5 and the rear end bulging part 6 as shown in FIGS. 3 and 4. A fishing rod is manufactured in which a fishing rod 8 is integrally formed with a rod rod 9, and a butt plug 9 is fitted to the rear end of the grip handle 8.

The prepreg 3 for forming the rod and the prepreg 4 for forming the grip handle are made by impregnating a woven fabric or a coordinating sheet made of carbon fiber or glass fiber in a semi-dry state with a thermosetting resin such as polyester resin or epoxy resin. It is preferable that the angle of inclination of the slanted portion of the prepreg 4 for forming the grip handle is larger than the angle of inclination of the slanted portion of the prepreg 3 for forming the rod.

Effects of the Invention The present invention includes a rod-forming prepreg having an oblique rear edge formed on a core metal whose rear end portion is smoothly bulged, the rear edge of which is located in front of the bulge portion of the core metal. After winding the rod-forming prepreg in the manner shown in FIG. By manufacturing fishing rods by this method, it is possible to integrally form a grip handle with a smoothly contoured shape that is easy to grip on the fishing rod at the same time as manufacturing the fishing rod, and the manufacturing process of fishing rods can be significantly streamlined and simplified. The handle of the fishing rod manufactured in this way is also made of the same material as the fishing rod, so the transmission of fishing information is smooth and can be detected sensitively.In addition, the weight of the rod is lighter than that of conventional fishing rods. It has an excellent feature that there is no risk of the grip handle coming off.

Claims (1)

[Claims] 1. A rod-forming prepreg with an oblique rear edge was wound around a core metal whose rear end was smoothly bulged so that the rear edge was located in front of the bulge of the core metal. After that, a grip handle-forming prepreg having an oblique front edge is wound from the rear part of the rod-forming prepreg wrapping part to the bulging part of the core metal, and then the outer peripheral surfaces of these are wrapped with tape. A method for manufacturing a fishing rod, which is then subjected to heat curing treatment, core removal, and tape peeling in the usual manner.
