[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod, and more particularly to a swing-out type fishing rod capable of sequentially storing a tip side rod body inside a rod body side rod body.
[0002]
[Prior art]
A conventional swing-type fishing rod (hereinafter referred to as a swing rod) is formed by connecting a plurality of rods, for example, an external rod arranged on the hand side and a tip side of the external rod. An internal housing that can be inserted into and stored in the external housing. And when using this swinging rod, the inner casing on the tip side is pulled out from the outer casing and fixed, and used as a single casing. During transportation, the inner housing on the tip side is inserted into the outer housing to make it compact.
[0003]
[Problems to be solved by the invention]
In the conventional swing rod, when the inner housing on the tip side is inserted into the outer housing on the foot side, the end surface on the tip side of the outer housing contacts the outer peripheral surface of the inner housing, and the outer peripheral surface of the inner housing May wear out. Various coatings are applied to the surface of the inner casing to improve water resistance, durability, and design, but the coating peels off due to contact with the end face of the outer casing. There is a fear.
[0004]
The subject of this invention is providing the swing type fishing rod which can be accommodated, without damaging the outer peripheral surface of a housing.
[0005]
[Means for Solving the Problems]
The fishing rod according to the first aspect of the present invention is a swing-out type fishing rod, and is connected to an external rod having an anti-wear resin layer on the inner peripheral surface of the tip end side so that the external rod can be stored on the tip side of the external rod. With an internal enclosure.
In this case, an anti-wear resin layer is formed on the inner peripheral surface of the tip side end portion of the outer casing which is likely to come into contact with the outer peripheral surface of the inner casing. This wear-resistant resin layer is softer than the resin layer constituting the casing, and does not wear other members even if it comes into contact with other members. As a result, the outer peripheral surface of the outer casing is not worn and damaged when the inner casing is taken in and out of the outer casing.
[0006]
In this case, since the antiwear resin layer is integrated with the external casing, it is possible to prevent the antiwear resin layer from peeling off.
[0008]
Here, the anti-wear resin layer is a cellulose fiber reinforced resin layer integrally formed with the external casing. Here, the cellulose fiber reinforced resin layer is a resin layer made of a synthetic resin reinforced by blending cellulose fibers. In this case, since the anti-wear resin layer is formed from a resin containing relatively soft cellulose fibers, other members are not worn while maintaining appropriate strength and rigidity. As this cellulose fiber, rayon fiber etc. can be illustrated.
[0009]
The method for manufacturing a fishing rod is a method for manufacturing a swing-out type frame in which another case is inserted, and includes the following steps.
◎ A step of applying a release agent to the core material, and a step of winding an anti-wear prepreg for forming an anti-wear resin layer at the tip end of the core material.
◎ A step of winding a prepreg for a casing.
[0010]
◎ A process of winding a protective tape around the outer peripheral surface of a prepreg for a skeleton to obtain a cocoon material.
◎ Baking process of firewood material.
◎ A step of removing the core material and removing the protective tape.
In this case, since the anti-wear prepreg and the prepreg for the casing are sequentially wound around the core material and fired, the anti-wear resin layer can be manufactured integrally with the casing, and the manufacture becomes easy. In addition, the durability of the anti-wear resin layer is also improved.
[0011]
The method for manufacturing a fishing rod further includes a step of cutting the end face of the rod material after the core material is extracted and the protective tape is peeled off.
[0012]
DETAILED DESCRIPTION OF THE INVENTION

A fishing line introduction hole 6 is provided on the surface for inserting the fishing line L from the reel 5 into the housing. The internal housing 2 can be accommodated by sequentially inserting a plurality of housings, and a top guide 7 is provided at the tip of the tip side. Then, the fishing line L guided from the reel 5 is introduced from the fishing line introduction hole 6 into the outer casing 1 and the inner casing 2 and guided from the top guide 7 to the outside.
[0013]
As shown in FIG. 2, the external housing 1 is a cylindrical member, and the inside is a housing storage portion 10 that can store the internal housing 2. The external housing 1 has a main body part 11 and an anti-wear resin layer 12 molded integrally with the main body part 11 on the inner peripheral surface of the tip side. As will be described in detail later, the main body 11 is formed by winding a sheet-like prepreg obtained by impregnating a carbon fiber reinforced fiber with a resin around a mandrel. It is molded from a prepreg impregnated with resin.
[0014]
As shown in FIG. 2, the internal housing 2 is a cylindrical member, and the inside is a cocoon storage portion 20 that can store another internal housing connected to the tip side. The internal housing 2 includes a main body part 21, a fitting male part 22 provided at a base side end part of the main body part 21 and having a larger diameter than the main body part 21, and a base side end face of the fitting male part 22. The bottom plug portion 23 is formed on the bottom. The main body 21 is formed by winding a sheet-like prepreg obtained by impregnating a carbon fiber reinforced fiber with a resin, like the main body 11 of the outer casing 1. The fitting male portion 22 is formed integrally with the main body portion 21 and matches the inner peripheral diameter of the tip side end portion of the outer casing 1. Further, the bottom plug portion 23 has a screw portion 23 a, and the screw portion 23 a can be screwed and fixed to the end surface of the fitting male portion 22.
[0015]
(Method for manufacturing the external housing 1)
The external scissors 1 employing one embodiment of the present invention are manufactured as follows.
As shown in FIG. 3A, first, a release agent (not shown) such as wax is applied to the outer periphery of the mandrel 100 having a predetermined taper, and polyester fiber is applied to the outer peripheral surface on the tip side. The anti-wear prepreg 101 impregnated with resin is wound. As the anti-wear prepreg 101, a polyester nonwoven fabric material obtained by impregnating a polyester fiber nonwoven fabric with a synthetic resin may be used.
[0016]
Next, as shown in FIG. 3B, a sheet-like prepreg 102 obtained by impregnating a carbon fiber reinforced fiber with a resin is wound while being pressed. A plurality of the prepregs 102 are wound, for example, four prepregs 102 are sequentially wound. Here, the innermost first prepreg is formed by using reinforcing fibers oriented in the length direction of the tape, and the reinforcing fiber groups are oriented in the circumferential direction of the outer casing 2. The second to fourth prepreg layers sequentially wound around the outer periphery of the first prepreg are formed by using reinforcing fibers oriented in the width direction of the tape, and the second to fourth reinforcing fiber groups are formed. The mandrel is oriented in the axial direction.
[0017]
In this way, as shown in FIG. 3 (c), after the anti-wear prepreg 101 and the plurality of prepregs 102 are wound, a protective tape (not shown) made of polyester terephthalate or polypropylene is wound around the outer periphery thereof. Turn to get cocoon material. The obtained raw material is fired by applying pressure from the outer peripheral side, the mandrel 100 is removed, and the protective tape is peeled off. Then, both ends are cut off, the surface is further polished and a necessary coating material is applied, and as shown in FIG. 4, an outer casing 1 having an abrasion-resistant resin layer formed on the inner peripheral surface of the tip end is manufactured. To do.
[0018]
