Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tip rod of a mid-range fishing rod, and more specifically, a tip of a fishing line guide member is provided so as not to impair the sliding characteristics of the fishing line and not to impair the elasticity of the rod. The present invention relates to a technique that can be provided inside the rod.

[0002]

2. Description of the Related Art Since the tip rod of a hollow fishing rod has a large degree of bending, the sliding resistance between the fishing line and the inner peripheral surface of the tip rod is greater than in other portions. In order to reduce such sliding resistance, it has been attempted to provide a fishing line guide ring on the inner peripheral surface of the rod. For example, JP-A-4-34
No. 1133 discloses that a fishing line guide ring made of a single fiber having a large diameter such as ceramic or boron is fixed to a stepped portion on the outer periphery of a core metal, and a reinforcing fiber is impregnated with a synthetic resin from the outer periphery of the ring. The prepreg is wound, and then the ring is projected and provided on the inner peripheral surface of the rod by applying pressure and firing by a conventional method. JP-A-7-1158
In Japanese Patent Laid-Open No. 78, a fishing line guide ring is covered on the outer circumference of a rubber tube coated on the outer circumference of a core metal, and a release agent or a resin inflow preventing member is arranged in front of and behind the fishing line guide ring and reinforced from the outer circumference. By winding a prepreg impregnated with synthetic resin around the fiber, and then pressurizing and firing by a conventional method,
The ring is projected on the inner surface of the rod.
According to the registered utility model No. 3013952, the fishing line guide ring is fixed to a predetermined position in the rod by inserting a fishing line guide ring fitted into the front and rear ends of the pipe into the rod.

[0003]

However, according to the invention of Japanese Patent Application Laid-Open No. 4-341133, the resin in the prepreg melts out during firing and the fishing line guide ring is buried in the prepreg, and the fishing line guide ring guides the fishing line. May not function as a body. Further, even if the fishing line guide ring is exposed from the inner peripheral surface of the rod, the synthetic resin that has been eluted and solidified around the ring sticks in a burr shape, so that the fishing line is more likely to be damaged. Further, since the ring is integrally attached to the inner peripheral surface of the rod, the ring may peel off when the rod bends, and the presence of the ring may adversely affect the bending and repulsion of the rod.

According to the invention of Japanese Patent Application Laid-Open No. 7-115878, the above-mentioned burr can be prevented by the rubber tube, the mold release agent or the resin inflow preventing member, but the rubber tube is covered before the molding and the mold release agent. Alternatively, since it is necessary to mount the resin inflow prevention member on the core metal and remove them after molding, there arises a problem that productivity is lowered. Further, since the diameter of the ring portion attached to the outer periphery of the core metal is larger than that of the other portion, when the rod-forming prepreg is wound around the outer periphery, cracks may occur in the ring or the prepreg may be twisted. Not only can the ring be reliably positioned and held in the rod, but the twisting of the fibers in the prepreg may cause breakage of the rod. Further, even if it is attempted to attach the ring only to a part such as the tip inside the rod tube, the twist may be further increased due to the difference in other diameters. Also in the case of the present invention, since the ring is integrally attached to the inner peripheral surface of the rod, there is a risk of peeling when the rod bends, and the presence of the ring may adversely affect the bending and repulsion of the rod.

Since the fishing line guide ring of Registered Utility Model No. 3013952 is fixed in the rod through the pipe, the pipe may impede the bendability of the rod, and the fishing line guide ring may extend over the entire length of the hollow fishing rod. It is difficult to attach locally because it needs to be inserted.

Therefore, an object of the present invention is to provide means for solving such a problem.

[0007]

In order to achieve the above object, the invention of claim 1 is to wrap a prepreg obtained by impregnating reinforcing fibers with a resin around a core metal, and pressurize and fire it by a conventional method. The formed tip rod body 3a of the formed fishing rod and the tip rod body 3a
