BACKGROUND OF THE INVENTION
The present invention relates to a fishing rod formed by connecting a plurality of rods.
[0002]
[Prior art]
Many recent fishing rods are provided with a plurality of rods, which are cylindrical bodies with a tapered taper, and these rods are connected to form a single fishing rod. For example, in the case of the swing-out type, when the small-diameter housing located on the tip side is sequentially stored inside the large-diameter housing located on the base side, and the small-diameter housing is pulled out on the tip side The outer periphery of the base side end of the small-diameter housing and the inner periphery of the tip end of the large-diameter housing are fitted.
[0003]
In such a portion for connecting the casings, precise matching of the diameters of both casings is required. However, when the rods are repeatedly fitted to each other, the rods are worn, and deformation bending may occur due to a stress load when used as a fishing rod. Therefore, from the past, for such a portion for connecting the casings, for example, a technique of laminating a prepreg using a special polyester fiber supplementarily (see, for example, Patent Document 1), a reinforcing fiber shaft A technique of laminating prepregs inclined with respect to the direction (for example, see Patent Document 2) has been proposed.

[Problem to be Solved by the Invention]
One problem in connecting such fishing rods is that, of course, two rods overlap each other at the portion where the rods are connected. The casing is generally configured by laminating prepregs in which reinforcing fibers are aligned in the axial direction of the casing in order to ensure the bending rigidity in the axial direction. For this reason, in the part where the two casings overlap so as to connect the casings, the amount of reinforcing fibers aligned in the axial direction is doubled compared to the other parts.
[0007]
With reference to FIG. 4, description will be made by taking as an example a case where the upper heel 51 is connected to the tip side of the heel 50 in a swinging manner.
The main rod 50 has an axial layer 50a made of a prepreg in which reinforcing fibers are oriented in the axial direction, and the upper collar 51 also has an axial layer 51a made of a prepreg in which reinforcing fibers are oriented in the axial direction (general rod). 50 and the upper collar 51 are fitted to each other so that the edge of the upper edge of the upper collar 51 is partially thickened and thickened. An auxiliary layer 51b is also laminated on the end of the heel side). When such a former fence 50 and the former upper collar 51 are connected, the axial layer 50a and the axial layer 51a exist in the range where the casings overlap (the X range in FIG. 4). Directional fibers are doubled compared to other parts. And such a doubling of the axial fibers partially increases the axial bending rigidity and impairs the continuous bending of the entire fishing rod.
[0008]
The subject of this invention is providing the fishing rod which can produce a favorable bend.
[0009]
[Means for Solving the Problems]
The fishing rod of the present invention is a fishing rod formed by connecting a plurality of rods, and includes a first rod having a fitting female portion within a certain range in the axial direction of the tip side end portion, and a rod side end portion. And a second housing having a fitting male part that can be fitted to the fitting female part in a certain range in the axial direction. The first casing is formed on the outer periphery of the main layer in a certain range in the axial direction of the main layer formed from the prepreg in which the reinforcing fibers are oriented in the axial direction and the tip side end where the fitting female portion is formed. And an auxiliary layer formed from a prepreg in which reinforcing fibers are oriented in the circumferential direction. And in a certain range in the axial direction of the tip side end portion where the fitting female portion is formed, this main layer is thinner than the other portions while the prepreg is wound an integer number of 1 or more. is there.
[0010]
In addition, the second casing includes a main layer formed of a prepreg in which reinforcing fibers are oriented in the axial direction, and a main layer in a certain range in the axial direction of the base side end where the fitting male part is formed. And an auxiliary layer formed from a prepreg in which reinforcing fibers are oriented in the circumferential direction laminated on the outer periphery. Then, in a certain range in the axial direction of the base side end where the fitting male part is formed, the main layer is thinned as compared with other parts while the prepreg is wound by an integer of 1 or more. It is.
[0011]
In such a fishing rod, the first housing and the second housing are connected to each other by fitting the fitting female portion to the fitting male portion. When the first housing and the second housing are connected, the main portion including the axial fiber is thinned in each of the fitting male portion and the fitting female portion, and the amount of the axial fiber is partially Without increasing, the partial axial bending stiffness will not unduly increase. And the continuous bending of the whole fishing rod is not spoiled.
[0012]
Further, in another fishing rod of the present invention, the main layer of the first rod body is 2 minutes in comparison with other portions in a certain range in the axial direction of the tip side end portion where the fitting female portion is formed. The main layer of the second casing is half the thickness of the main layer of the second casing as compared with the other parts in a certain range in the axial direction of the base end where the fitting male part is formed. That's it.
In this fishing rod, in the fitting male portion and the fitting female portion where the first rod body and the second rod body overlap, the main layer of each rod body is half of the other part. Therefore, the amount of the main layer (that is, the amount of the axial fibers) similar to the other portions is maintained by overlapping the fitting male portion and the fitting female portion. The bending rigidity in the axial direction with respect to the other portions will not be unduly increased. And the continuous bending of the whole fishing rod is not spoiled.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a fishing rod employing one embodiment of the present invention is connected to a main rod 1, a head rod 2, a middle rod 3, and a tip rod 4 in order of the head side of the rod 1. Has been. Each casing is a cylindrical member with a tapered taper made of a prepreg material obtained by impregnating carbon fiber or glass fiber with a synthetic resin.
[0014]
A reel seat 5 to which the reel R can be detachably mounted is provided on the peripheral surface of the base 1 on the base side, and a butt plug 6 is detachably attached to the end on the base side. A fishing line introduction port 7 for introducing the fishing line from the reel R into the rod body is formed on the peripheral surface on the tip side of the reel sheet 5, and the fishing line is supplied to the fishing line introduction port 7 on the peripheral surface near the fishing line introduction port 7. A fishing line introduction guide 8 for guiding is attached. On the other hand, the inside of the former rod 2 to the tip rod 4 is a fishing line passage through which the fishing line L is inserted, and the fishing line support for supporting the fishing line and reducing the contact area with the inner peripheral surface as necessary. A protrusion is formed integrally with each housing. A top guide 9 is connected to the tip end of the tip rod 4, and the fishing line L from the reel R is introduced into the rod body from the fishing line introduction port 7 via the fishing line introduction guide 9 and sequentially led to the tip side. , Derived from the top guide 9 to the outside.
[0015]
In order to connect the respective casings to each other, a predetermined mating male part and a mating female part are formed on each of the main bark 1 to the head barb 4. As a result, each housing is connected and fixed. In the following, the connecting portion will be described with reference to the former fence 1 and the former upper fence 2 as an example.
As shown in FIG. 2, in the heel 1 and the heel 2, the tip side end inner peripheral surface of the heel 1 is a fitting female part 1 a, and the heel side end of the heel 2 The outer peripheral surface is the fitting male part 2a. And it is adjusted so that each inner diameter and outer diameter may coincide.
[0016]
As described above, the main shaft 1 is a tubular member tapered as a whole, and the fitting female portion 1a that is a certain range in the axial direction of the end portion on the tip side is swelled so as to swell toward the outer peripheral surface side. It is thickened. Although the axial length of the fitting female portion 1a varies depending on the diameter of the housing, it is generally preferable that the axial length is about 3 to 4 times the diameter of the housing. And this marion 1 is constant in the axial direction of the main layer 10 formed from a prepreg in which reinforcing fibers are oriented in the axial direction of the marshal 1 and the tip side end where the fitting female part 1a is formed. In this range, the auxiliary layer 11 formed from a prepreg having reinforcing fibers oriented in the circumferential direction laminated on the outer periphery of the main layer 10 is laminated and integrated. In FIG. 2, the main layer 10 and the auxiliary layer 11 are separately shown for reference, but both are baked and integrated as will be described later.
[0017]
The main layer 10 of the base rod 1 is thinner than the other portions in a certain range of the tip side end portion that becomes the fitting female portion 1a. Specifically, it is preferable that the thickness of the main layer 10 is set to a half thickness of the other portions in the fitting female portion 1a. On the other hand, the auxiliary layer 11 is a portion disposed in place of the main layer 10 in order to maintain the strength of the main shaft 1 in the fitting female portion 1a portion where the main layer 10 is thinned.
[0018]
In this embodiment, the auxiliary layer 11 is laminated on the fitting female portion 1a portion, and the fitting female portion 1a portion is thickened so as to swell to the outer peripheral surface side from the other portions. It is also possible to laminate the auxiliary layer 11 so that the diameter of the fitting female portion 1a matches that of the other portions.
As shown in FIG. 2, the upper collar 2 is a tubular member having a tapered taper as a whole, as is the case 1. The former upper cage 2 is connected to the former cage 1 in a swing-out manner, and can be inserted into the former cage 1 from the tip side and stored. In the fitting male part 2a, which is a certain range in the axial direction of the end part on the heel side of the upper upper collar 2, the outer diameter is increased so as to swell toward the outer peripheral surface side. In addition, the upper collar 2 also has a main layer 20 formed of a prepreg in which reinforcing fibers are oriented in the axial direction of the upper collar 2, and an axial direction of the proximal end where the fitting male portion 2a is formed. The auxiliary layer 21 formed of a prepreg having reinforcing fibers oriented in the circumferential direction laminated on the outer periphery of the main layer 20 in a certain range is laminated and integrated.
[0019]
The main layer 20 of the upper heel 2 is thinner than the other portions in a certain range of the heel side end that becomes the fitting male portion 2a. Specifically, as in the case of the base rod 1 described above, in the fitting male portion 2a moiety, to aim to the thickness of the main layer 20 and the first thickness of the half of the other portions Is preferred.
Here, although the explanation has been made with respect to the main rod 1 and the upper upper rod 2, the fitting portion has the same structure also in the other rods.
[0020]
Next, the manufacturing method of the rod which comprises the fishing rod concerning this embodiment is demonstrated taking the former rod 1 as an example.
As shown in FIG. 3A, first, a mandrel (core material) 100 having a predetermined taper taper is prepared. Moreover, a mold release agent is apply | coated to the surrounding surface of the mandrel 100 as needed. Then, the first prepreg P1 is wound around the outer peripheral surface of the mandrel 100 by one ply or several plies. The first prepreg P1 is obtained by uniformly aligning reinforcing fibers such as carbon fibers in the axial direction and impregnating them with a synthetic resin. The axial length of the first prepreg P1 is set so as to have the entire axial length of the main shaft 1.
[0021]
Next, as shown in FIG.3 (b), the 2nd prepreg P2 is further wound around the outer peripheral surface of the 1st prepreg P1. The second prepreg P2 is also the one in which reinforcing fibers such as carbon fibers are aligned and oriented in the axial direction and impregnated with a synthetic resin. The axial length of the second prepreg P2 is set to have an axial length shorter than the total axial length of the main shaft 1. Specifically, the second prepreg P2 having an axial by the length shorter axial length of the first prepreg P 1 from the fitting female part 1a. The second prepreg P2 is wound around the outer circumference of the first prepreg P1 with the base side aligned with the first prepreg P1 so as to form a portion that is not wound on the tip side. The number of turns of the second prepreg P2 is set to be the same as the number of turns of the first prepreg P1. The first prepreg P1 and the second prepreg P2 constitute the main layer 10. By winding the first prepreg P1 and the second prepreg P2 in the same number of plies, the thickness of the main layer 10 is increased. In the part which becomes the fitting female part 1a, it becomes a half thickness.
[0022]
At this time, the number of windings of the first prepreg P1 and the second prepreg P2 is set so that the wall thickness does not change in the circumferential direction, particularly at least at the tip side edge, for example, one turn or several turns. It is preferable to wind it uniformly).
Then, as shown in FIG.3 (c), the 3rd prepreg P3 is wound around the part by the side of the tip which has not wound 2nd prepreg P2. The third prepreg P3 is formed by impregnating a synthetic resin after the reinforcing fibers are aligned in the circumferential direction of the casing, and forms the auxiliary layer 11. This third prepreg P3 is wound several plies. As shown in FIG. 2, the third prepreg P3 for forming the auxiliary layer 11 is wound thicker than the laminated portion of the second prepreg P2.
[0023]
Further, a molding tape such as polypropylene is wound around the outer circumference of each of these prepregs in a spiral manner without pressure and fired in a furnace. After firing, the molding tape is peeled off, the mandrel 100 is pulled out, both ends are cut and trimmed to a predetermined axial length, the peripheral surface is polished and smoothed, and the peripheral surface is coated to manufacture the base 1.
In addition, also in cases other than the original case 1, each case can be manufactured by the same manufacturing method. For example, in the case where a fitting female part is formed at the tip side end part and a fitting male part is formed at the tip side end part as in the case of the upper collar 2, the second prepreg P2 is connected to the tip side and the heel side. It winds so that a clearance gap may be formed in the both ends.
[0024]
In such a fishing rod, for example, in the former rod 1 and the former rod 2, the fitting rod 1a is fitted on the fitting male portion 2a of the former rod 2 so that the former rod 2 is moved to the former rod. When pulled out toward the tip of 1, the former heel 2 and the former heel 1 are connected and fixed to each other. The mating male part 2a and the mating female part 1a each have a thin main layer 10 containing axial fibers, in particular, one-half compared to other parts, and the amount of axial fibers is It does not increase partially and is equivalent to other parts. The circumferential fibers of the auxiliary layer 11 are not greatly involved in the bending rigidity in the axial direction of the fishing rod or rod. Therefore, the partial axial bending rigidity is not unduly increased. If the same structure is applied to the connecting portion between the other rod bodies, the continuous bending of the entire fishing rod is not impaired.
[0025]
In addition, in the said embodiment, although the case where each chassis is connected with a swing-out form is illustrated, it is also possible to apply also to a connection-type fishing rod.
[0026]
