Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a fishing rod used for fishing, more specifically, on the outer surface of a hollow rod main body formed in a loose cone shape, in the longitudinal direction of the rod main body. The present invention relates to a fishing rod configured to fix a movable fishing line guide.

(Prior Art) Generally, since the taper of this kind of rod is very loose and the accuracy of the outer diameter of the rod is not high, it is difficult to accurately fix the fishing line guide to the predetermined position of the guide fixing portion of the rod body. Is. Therefore, conventionally, as seen in Japanese Patent Laid-Open No. 63-237725, the outer surface of the guide fixing portion of the hollow rod body formed by winding a prepreg impregnated with synthetic resin on high-strength fiber to form a loose cone shape. The prepreg made of the same material as the prepreg is wound to integrally provide a build-up layer, and the outer surface of the build-up layer is formed in a polygonal shape to prevent movement and rotation of the fishing line guide. Proposed.

(Problems to be solved by the invention) However, according to this conventional one, since the outer surface of the guide fixing portion of the hollow rod body is built up with a prepreg to form a thick wall, the outer surface of the built-up layer and the rod are There is a problem that a large step is formed between the outer surface of the main body and a large concentrated load acts on the step of the guide fixing portion during fishing, resulting in poor durability.

The present invention has been devised in view of the above problems, and an object thereof is to prevent a large concentrated load from acting on the guide fixing portion while the fishing line guide can be accurately fixed to the guide fixing portion of the rod body. The point is to provide a fishing rod that can be done.

(Means for Solving the Problems) However, according to the present invention, a hollow rod body (1) formed by winding a prepreg impregnated with synthetic resin on high-strength fiber to form a loose conical shape is provided on the outer surface of the hollow rod body (1). A fishing rod configured to fix a fishing line guide (B) that is movable in the longitudinal direction of the rod body (1), wherein a guide fixing portion of the rod body (1) has a diameter of the rod body (1). A hollow bulging portion (2) is provided which has a substantially constant thickness and a diameter that increases at a rate of change larger than the rate of change, and whose rate of change changes continuously with the outer peripheral surface of the rod body (1). The fishing line is characterized in that the rotation preventing means (3) for the fishing line guide (B) is provided flush with the outer surface of the rod body (1) on the outer surface of (2).

(Function) The guide fixing portion of the rod body (1) is a sharp cone-shaped hollow bulging portion (2) of approximately the same thickness that expands at a rate of change larger than the rate of change of the diameter of the rod body (1). Since the fishing line guide can be accurately stopped at the guide fixing portion of the rod body (1), the rotation of the fishing line guide is prevented by the rotation stopping means provided on the outer surface of the hollow bulging portion (2). You can do it.

(Example) In the examples shown in FIGS. 1 and 2, the hollow rod body (1) formed by winding a prepreg in which high-strength fibers are impregnated with a synthetic resin is wound to form a loose cone, and A sharp conical hollow bulging portion (2) of substantially the same thickness that expands at a rate of change greater than the rate of change of the diameter of the rod body (1) is provided, and the rod body (2) is provided on the outer surface of the bulging portion (2). 1) A rotation stopping means for the fishing line guide (B) is provided which is movable in the length direction.

Specifically, the rod body (1) has a molding portion having a size corresponding to the inner diameter of the hollow cone body (1) having a tapered conical slope, and the middle portion of the molding body in the longitudinal direction. A core metal (A) having a steep conical portion (a) that expands at a rate of change larger than the rate of change of the diameter of the rod body (1) is used in a portion facing the guide fixing portion of the core metal (A). The prepreg is wound around the outer surface of (A), pressure-fired in a conventional manner to form a hollow rod body (1), and the rod body (1) is fixed to the guide fixing portion of the rod body (1). A sharp cone-shaped hollow bulging portion (2) of substantially the same thickness that expands at a rate of change larger than the rate of change in diameter is provided, and the hollow bulging portion (2) of the rod body (1) is also provided.
A prepreg made of the same material as the prepreg is wound around the outer surface to provide a detent layer (3), and the tip end surface of the detent layer (3) is brought into close contact with the outer surface of the rod body (1) and the detent The large-diameter side end surface of the layer (3) is formed flush with the outer surface of the rod body (1) so that a large concentrated load does not act on the guide fixing portion, and the detent layer (3)
A large number of detent grooves (4) extending in the length direction are provided at predetermined intervals in the circumferential direction on the outer surface of the detent layer (3).
The detent groove (4) constitutes the detent means.

In addition, the whirl-stop layer (3) is wound around the outer periphery of the steep conical portion (a) after winding the prepreg for a rod body around a core metal and before pressure firing, and is applied in a conventional manner. Although it is pressure-fired to be integrally formed with the rod body (1), it may be pressure-fired separately from the rod body (1) and integrally connected to the rod body (1).

In the fishing rod constructed as described above, a fishing line guide (B) having a large number of axial projections on the inner peripheral surface is inserted into the guide fixing portion of the rod main body (1), and the axial direction of the inner surface of the guide. The ridges are engaged and fixed in the detent groove (4).

Since the guide fixing portion is provided with the hollow conical hollow bulging portion (2), the fishing line guide (B) is provided.
Can be accurately stopped at the guide fixing portion, and since the rotation preventing groove (4) is provided on the outer surface of the hollow bulging portion (2) of the guide fixing portion, the fishing line guide (B) It can prevent rotation.

In the embodiment described above, the whirl-stop layer (3) is provided on the outer surface of the hollow bulging portion (2), and the whirl-stop layer (3) is provided.
Although the rotation preventing groove (4) is provided on the outer surface of the fishing line to prevent the fishing line guide from rotating, a rotation preventing ridge may be provided instead of the rotation preventing groove, or the rotation preventing layer may be provided. The detent ridge may be provided without providing (3), and the structure of the detent means is not particularly limited.

When the whirl-stop layer (3) is provided, the whirl-stop layer (3) is made of a prepreg made of the same material as the rod body prepreg as in the embodiment, and is made of a material different from the rod body prepreg. It may be used or may be formed of synthetic resin without high-strength fiber, and its material is not particularly limited.

(Effect of the Invention) As described above, the present invention can fix the fishing line guide to the guide fixing portion of the rod body so as not to move and rotate, and prevent a large concentrated load from acting on the guide fixing portion. The durability of the fishing rod can be increased.
