The present disclosure relates to a fishing rod reel seat, a fishing rod handle member comprising the reel seat, and a fishing rod comprising the fishing rod reel seat and the fishing rod handle member.
In the related art, various fishing rods each including a fishing rod reel seat and a grip have been known.
In such a fishing rod, a fishing rod reel seat and a fishing rod grip are usually placed on a rod body, and a reel leg placing portion for placing a reel leg on an upper side or a lower side of a main body is formed on the fishing rod reel seat.
As such a fishing rod, for example, Patent Literature 1 discloses a tubular body for a rod body, which is formed as a fishing rod by being baked in a state of being formed in a predetermined cylindrical body, in which an intermediate layer elastically deformable even after the baking is interposed between a layer body in which reinforcing fibers aligned in a fiber direction and a thermosetting resin are integrally formed and a layer body in which the reinforcing fibers aligned in the fiber direction and the thermosetting resin are integrally formed, and a through hole that allows permeation of part of two layer bodies into the intermediate layer and integrates the two layer bodies is formed.
Furthermore, Patent Literature 2 discloses a tubular body obtained by forming a layer on the outermost surface or innermost surface of a predetermined portion of a prepreg wound around a core metal and baking the layer, the layer being formed by causing a thermosetting resin material of which viscosity decreases when a temperature during baking increases to overlap with a mat-shaped resin material that melts in a temperature range higher than the temperature at which the viscosity of the resin material decreases and in a temperature range lower than the temperature of baking.
However, in the tubular body disclosed in Patent Literature 1, a tubular body for a rod body is formed in which an intermediate layer elastically deformable even after baking is interposed between a layer body in which reinforcing fibers aligned in a fiber direction and a thermosetting resin are integrally formed and a layer body in which the reinforcing fibers aligned in the fiber direction and the thermosetting resin are integrally formed, and a through hole that allows permeation of part of two layer bodies into the intermediate layer and integrates the two layer bodies is formed, but there is a problem that in a molded rod body, the absence of resin and the fiber fuzz and void on an inner surface are likely to occur, the inner surface processability is deteriorated, and it is difficult to perform molding so as to satisfy design target performance.
Furthermore, even in the tubular body disclosed in Patent Literature 2, a tubular body is formed, which is obtained by forming a layer on the outermost surface or innermost surface of a predetermined portion of a prepreg wound around a core metal and baking the layer, the layer being formed by causing a thermosetting resin material of which viscosity decreases when a temperature during baking increases to overlap with a mat-shaped resin material that melts in a temperature range higher than the temperature at which the viscosity of the resin material decreases and in a temperature range lower than the temperature of baking. However, there is a problem that in a molded rod body, the absence of resin and the fiber fuzz and void on an inner surface are likely to occur, the inner surface processability is deteriorated, and it is difficult to perform molding so as to satisfy design target performance.
The present disclosure has been made in view of the above circumstances, and an object of the present disclosure is to provide a fishing rod reel seat, a fishing rod handle member comprising the reel seat, and a fishing rod comprising the fishing rod reel seat and the fishing rod handle member, in which the inner surface processability is high, and the absence of resin and the fiber fuzz on an inner surface are less likely to occur. Purposes of the present disclosure other than this object will be clarified by referring to the overall description disclosed herein.
According to an embodiment of the present disclosure, there is provided a fishing rod handle member made by integrally molding a reel seat main body having a reel leg placing portion on which a reel leg is placed and a grip connected to the reel seat main body, in which an outer layer of the fishing rod handle member is formed of carbon fiber reinforced plastic and an inner layer of the fishing rod handle member is formed of resin.
The fishing rod handle member according to the embodiment of the present disclosure is formed in a hollow shape.
In the fishing rod handle member according to the embodiment of the present disclosure, an end of a rod body for a fishing rod is attached to one end of the reel seat main body on an opposite side of the grip.
In the fishing rod handle member according to the embodiment of the present disclosure, carbon fibers formed of the carbon fiber reinforced plastic are continuously formed in a longitudinal direction of the fishing rod handle member.
According to the embodiment of the present disclosure, there is provided a fishing rod comprising: any one of the fishing rod handle members described above; and a rod body.
According to the embodiment of the present disclosure, there is provided a fishing rod reel seat main body having one end attached to a rod body for a fishing rod and the other end attached to a fishing rod grip, the fishing rod reel seat main body comprising a reel leg placing portion on which a reel leg is placed, the fishing rod reel seat main body being integrally molded with the reel leg placing portion as a whole.
According to the embodiment described above, there can provided the fishing rod reel seat, the fishing rod handle member comprising the reel seat, and the fishing rod comprising the fishing rod reel seat and the fishing rod handle member, in which the inner surface processability is high, and the absence of resin and the fiber fuzz on an inner surface are less likely to occur.
Hereinafter, an embodiment of a fishing rod according to the present disclosure will be specifically described with reference to the accompanying drawings. Components common to a plurality of drawings are denoted by the same reference numerals throughout a plurality of the drawings. Note that the drawings are not necessarily drawn to scale for convenience of description.
The rod body 2 is constituted by, for example, connecting a base rod 3, a middle rod 5, a tip rod 7, and the like to each other. These rod bodies are joined to each other, for example, as an ordinarily jointed type. The base rod 3, the middle rod 5, and the tip rod 7 can be joined to each other as a telescopic type, an inversely jointed type, a socket-and-spigot jointed type, or any other known joining type. The rod body 2 may be formed by a single rod body.
The base rod 3, the middle rod 5, and the tip rod 7 are each formed by, for example, a tubular body made of a fiber-reinforced resin. This tubular body made of a fiber-reinforced resin is formed by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core metal, and heating and curing the prepreg sheet. As the reinforcing fibers contained in the prepreg sheet, for example, carbon fibers, glass fibers, and any other known reinforcing fibers can be used. As the matrix resin contained in the prepreg sheet, a thermosetting resin such as an epoxy resin can be used. After the prepreg sheet is cured, the core metal is removed. Furthermore, an outer surface of the tubular body is appropriately polished. Each of the rod bodies may be formed in a solid state.
In the illustrated embodiment, the base rod 3, the middle rod 5, and the tip rod 7 comprise a plurality of the fishing line guides 10 (fishing line guides 10A to 10D) for guiding a fishing line fed from the reel 6 attached to the reel seat 9. More specifically, the base rod 3 comprises the fishing line guide 10A, the middle rod 5 comprises the fishing line guide 10B, and the tip rod 7 comprises the fishing line guide 10C. The tip rod 7 comprises the top guide 10D at a tip thereof, but details thereof are omitted.
Next, a reel seat main body 12 and the reel seat 9 will be described with reference to
Furthermore, the reel seat main body 12 comprises a grip portion 12b that is slightly bulged from the opposite side of the reel leg placing surface 12a and has an easy-to-grip curved outer surface that supports a thenar and an area near the thenar when gripped with a gripping hand.
The reel leg placing surface 12a of the reel seat main body 12 can be formed flat or substantially flat with a curvature greater than that of another circumferential portion (for example, the grip portion 12b) adjacent to the reel leg placing surface 12a of the reel seat main body 12, and is formed so as to extend in an axial direction of the reel seat main body 12 illustrated in
A moving hood 22 is attached to the other end (rod tip side) of the reel seat main body 12 so as to be movable in an axial direction. The reel seat main body 12 and the moving hood 22 may be collectively referred to as the reel seat 9, but details thereof are omitted.
Next, a fishing rod handle member 20 according to the embodiment of the present disclosure will be described with reference to
As illustrated in the drawing, in the fishing rod handle member 20 according to the embodiment of the present disclosure, the reel seat main body 12 having the reel leg placement portion 12a on which a reel leg 6b is placed, the grip 4 connected to the reel seat main body 12 are integrally molded, the outer layer 18 of the fishing rod handle member is formed of carbon fiber reinforced plastic, and the inner layer 17 of the fishing rod handle member is formed of resin. Furthermore, the fishing rod handle member 20 according to the embodiment of the present disclosure is formed in a hollow shape.
Here, the outer layer 18 can be formed of CFRP or CFRTP, but the present disclosure is not limited thereto. Furthermore, the inner layer 17 can be formed of ABS, acryl, PEI, or nylon, but the present disclosure is not limited thereto. As the resin used for the inner layer 17, a resin having good affinity with the resin contained in the outer layer 18 can be appropriately selected and used. In this manner, adhesion and adhesiveness between the outer layer 18 and the inner layer 17 can be improved.
In the fishing rod handle member 20 according to the embodiment of the present disclosure, it is possible to provide a fishing rod handle member comprising the reel seat that has high inner surface processability and in which the absence of resin and the fiber fuzz on the inner surface are less likely to occur.
Next, the fishing rod handle member 20 according to the embodiment of the present disclosure will be described with reference to
In the fishing rod handle member 20 according to the embodiment of the present disclosure, the fishing rod handle member 20 is made of carbon fiber reinforced plastic (CFRP). Furthermore, as described above, the outer layer 18 of the fishing rod handle member 20 may be made of CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid thereof. Since the fishing rod handle member 20 is made of such a material, it is possible to suppress an increase in weight while ensuring sufficient rigidity and strength as the handle member 20 used for the fishing rod. Furthermore, a resin material can be used for the inner layer 17 inside the outer layer 18 of the fishing rod handle member 20. In this manner, it is possible to form the fishing rod handle member comprising the reel seat that has high inner surface processability and in which the absence of resin and the fiber fuzz on the inner surface are less likely to occur.
More specifically, in the case of only the outer layer 18, when the handle member contains less resin due to variations in molding according to the core member, molding conditions, and the like to be described later, physical properties related to strength deteriorate. For example, the crushing strength of the annular portion is reduced, or the grip is easily bent. Since the inner layer 17 is present inside the outer layer 18, the resin necessary for fibers can be supplied, and thus physical properties can be stabilized (the lower limit of strength can be guaranteed). Furthermore, in a case where a component is inserted into or bonded to the inner layer 17, it may be necessary to perform additional processing on the inner diameter according to the dimension of the component, but there is a problem that a processing allowance cannot be secured when the inner side is fuzzy. However, as in the present disclosure, since the processing allowance can be sufficiently secured due to the presence of the inner layer 17 inside the outer layer 18, it is possible to mold the handle member having a more flexible and stronger structure.
Furthermore, as illustrated in
In the fishing rod handle member 20 according to the embodiment of the present disclosure, the end 15 of the reel seat main body 12 has a length (A) of 20 mm to 50 mm. In this manner, as described above, it is not necessary to cause the rod body to pass through the entire or substantially the entire fishing rod handle member 20. Therefore, the weight can be significantly reduced.
Here, as a method for attaching the end 13 of the rod body 3 for a fishing rod to the fishing rod handle member 20, for example, fitting (press-fitting), bonding, or fastening is conceivable, but the method is not limited thereto. The attachment methods described above have an advantage that attachment and detachment between the rod body and the handle member is easier.
Next, the fishing rod handle member 20 according to the embodiment of the present disclosure will be described with reference to
The fishing rod 1 according to the embodiment of the present disclosure comprises any one of the fishing rod handle member 20 and the rod body 3. In the fishing rod 1 according to the embodiment of the present disclosure, it is possible to provide a fishing rod that has high inner surface processability and in which the absence of resin and the fiber fuzz on the inner surface are less likely to occur.
The fishing rod reel seat main body 12 according to the embodiment of the present disclosure having on end attached to the rod body 3 for a fishing rod and the other end attached to the fishing rod grip 4 comprises the reel leg placing portion 12a on which the reel leg 6a is placed, the fishing reel seat main body 12 being integrally molded with the reel leg placing portion 12a as a whole. The outer layer 18 of the fishing rod reel seat main body 12 is formed of carbon fiber reinforced plastic and the inner layer 17 of the fishing rod reel seat main body 12 is formed of the resin. Furthermore, the reel seat main body 12 according to the embodiment of the present disclosure is formed in a hollow shape.
In the fishing rod reel seat main body 12 according to the embodiment of the present disclosure, it is possible to provide a reel seat main body 12 that has high inner surface processability and in which the absence of resin and the fiber fuzz on the inner surface are less likely to occur.
In the fishing rod handle member 20 according to the embodiment of the present disclosure, carbon fibers formed of the carbon fiber reinforced plastic (CFRP) are continuously formed in a longitudinal direction of the fishing rod handle member. In this manner, it is possible to reduce the weight by securing flexural rigidity and allow the vibration of the rod due to the fish bite to be transmitted to the hand in a sensitive manner.
Next, a method of molding the fishing rod handle member 20 according to the embodiment of the present disclosure will be described with reference to
Next, as illustrated in
Then, as illustrated in

Next, as illustrated in
In this manner, the fishing rod handle member 20 according to the embodiment of the present disclosure, that is, the fishing rod handle member 20, in which the reel seat main body 12 having the reel leg placement portion 12a on which the reel leg 6a is placed, and the grip 4 connected to the reel seat main body 12 are integrally molded, the outer layer 18 of the fishing rod handle member is formed of carbon fiber reinforced plastic, and the inner layer 17 of the fishing rod handle member is formed of the resin, is formed. Here, the inner layer 17 is formed by causing an unmeltable resin formed on the surface layer of the core member to adhere to the outer layer 18.
In the fishing rod handle member 20 formed in this manner according to the embodiment of the present disclosure, it is possible to provide a fishing rod handle member comprising the reel seat that has high inner surface processability and in which the absence of resin and the fiber fuzz on the inner surface are less likely to occur.
