[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rod constituting a fishing rod used for fishing, and more particularly, to a small-diameter point rod positioned closest to the tip.
[0002]
[Prior art]
Many conventional fishing rods form a single fishing rod by connecting a plurality of rods in a swing-out manner or a cascade manner. Each of these casings is a cylindrical body with a tapered taper, and many recent casings are manufactured from so-called fiber reinforced resin. Each rod has a small diameter from the large-diameter marsh located closest to the head side to the rods sequentially arranged on the tip side. is there.
[0003]
In this way, by gradually reducing the diameter of the rod on the tip of the tip, when the fish hits the device connected to the tip of the fishing line, the entire fishing rod curves gradually and gradually from the tip of the fishing rod, and good fishing operation Is possible. In addition, the tip of the tip with the smallest diameter on the tip side reacts to subtle movements of the device, so that the fisher is informed of the catch of the fish like an antenna.
[0004]
From such a request, it is required to make the ear buds as small as possible. In addition, for the reaction of the sharp tip, not only reducing the diameter but also making efforts to set the thickness of the tubular body that is the tip of the tip thin.
[0005]
[Problems to be solved by the invention]
In response to the above request, the diameter and thickness of the koji rice bran have been reduced, but this reduction in diameter and thinning also leads to a decrease in the physical strength of the koji koji, and there is a limit to the reduction in diameter. Has occurred.
An object of the present invention is to provide a scissors with a scissors having sufficient flexibility while maintaining a necessary strength.
[0006]
[Means for Solving the Problems]
The tip rod of the invention 1 is a tip rod that is a cylindrical body with a tapered taper that is disposed closest to the tip of a fishing rod formed by connecting a plurality of rods, and includes a glass fiber or a carbon fiber. The fiber is impregnated with a synthetic resin, and a prepreg material in which the reinforcing fibers are arranged so as to be inclined in two positive and negative directions from the axial direction of the casing is constituted by laminating 1 to 3 layers , an inner layer for maintaining the longitudinal or torsional stiffness of the rod body, is disposed on the outer periphery of the inner layer, a nonwoven fabric prepregs impregnated with synthetic resin nonwoven fabric made of polyester fibers are laminated 2-5 layers min, top rod that includes a nonwoven layer Ru increasing the thickness without increasing the bending stiffness.
[0007]
In this tip, (1) prepreg material in which glass fiber is impregnated with synthetic resin, or (2) reinforcing fiber such as glass fiber or carbon fiber is skewed in the positive and negative directions from the axial direction of the casing. An inner layer is formed from the arranged prepreg material.
This "(2) prepreg material in which reinforcing fibers such as glass fiber or carbon fiber are skewed in two positive and negative directions from the axial direction of the housing" is synthesized by aligning predetermined reinforcing fibers in one direction. A method in which two prepregs impregnated with resin are arranged so that the reinforcing fibers are inclined in two positive and negative directions from the axial direction of the casing, and these two prepregs are laminated, or A method of obtaining a prepreg material by impregnating with a synthetic resin after pre-orientation so as to be inclined in two positive and negative directions from the axial direction of the housing is conceivable. By laminating 1 to 3 layers of such a prepreg, the minimum required bending / twisting strength in the longitudinal direction or twist direction of the casing is maintained.
[0008]
On the other hand, the nonwoven fabric layer formed by laminating the nonwoven fabric prepreg for the predetermined number of layers on the outer periphery increases the thickness of the spikelet without excessively increasing the bending stiffness in the longitudinal direction, and the physical properties required for the spikelet Maintains the desired strength.
The spikelet of the invention 2 is the spikelet of the invention 1, and further includes an auxiliary prepreg layer laminated on the outer periphery of the heel side end of the nonwoven fabric prepreg.

DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the fishing rod employing the first embodiment of the present invention has a marine rod 1, an upper rod 2, a middle rod 3, and a habit rod 4 connected to the head side of the marine rod 1. is doing. Each of these cases is a tapered cylindrical member made of a predetermined prepreg material. Sequentially connected in a swing-out manner that can be stored inside the housing on the heel side, and the inner peripheral surface of the tip side end and the outer peripheral surface of the heel side end of each case are fitted to fit together at the time of connection. It is a joint part. In addition, although this fishing rod is comprised from four rods, it is not limited to this, The number of rods can be set arbitrarily.
[0011]
The main rod 1 has a reel sheet 5 that can be detachably mounted on a reel 6 provided on the peripheral surface of the heel side, and a butt plug 7 that is detachably mounted on the end of the heel side. . Further, a fishing line guide 8 for sequentially guiding the fishing line from the reel 5 to the tip side at a certain interval in the axial direction is disposed on the peripheral surface of each housing. And the top guide 9 is mounted | worn with the tip side edge part of the tip tip 4 located in the most tip side.
[0012]
The main rods 1 to 3 are cylindrical bodies with a tapered taper manufactured by firing a prepreg material in which a reinforcing fiber such as carbon fiber or glass fiber is impregnated with a synthetic resin in a furnace. The manufacturing method is as follows, for example. First, a core material having a predetermined taper is prepared. A prepreg sheet, which is made by sheeting carbon fibers in the axial direction or circumferential direction and then impregnated with an epoxy resin and processed into a sheet, is wound around this core material. Further, similar prepreg sheets or other types of prepreg sheets or prepreg tapes are sequentially wound and laminated as necessary. And after baking these and solidifying them integrally, the core material is pulled out and necessary surface treatment is performed. In addition, a necessary fitting portion is formed at the base side end portion or the tip side end portion of a certain casing, which is a portion for connecting a certain casing to another casing.
[0013]
The spikelet 4 is a rod having the smallest diameter arranged on the most tip side. It is a tapered cylindrical body that is reduced in diameter toward the tip side like other rod bodies. As shown in FIG. 2, the tip 4 has a two-layer structure of an inner layer 10 positioned on the inner peripheral surface side and a nonwoven fabric layer 11 positioned on the outer peripheral surface side.
The inner layer 10 is a prepreg material in which a glass fiber is impregnated with a synthetic resin, or a reinforcing fiber in which a synthetic resin is impregnated, and the reinforcing fiber is disposed so as to be inclined in two positive and negative directions from the axial direction of the casing. It consists of prepreg material. In this type of prepreg, the angle at which the reinforcing fibers are skewed is set in a range of ± 0 to 45 degrees, preferably about 20 to 45 degrees from the axial direction. By setting it in such a range, good torsional strength and the like can be maintained.
[0014]
The inner layer 10 is formed by laminating one to three layers of these materials processed into a sheet shape or a tape shape. When laminating a plurality of materials, not only the same kind of materials but also different materials may be laminated.
The nonwoven fabric layer 11 is composed of a nonwoven fabric prepreg obtained by impregnating a nonwoven fabric formed of polyester fiber or the like with an epoxy resin or the like. The nonwoven fabric prepreg is formed into a sheet or a tape and then laminated with 2 to 5 layers of this material. Also in this case, when laminating a plurality of materials, not only the same type of materials but also different materials may be laminated. Ultimately, the thickness of the tip 4 is about 0.1 to 0.4 mm due to the lamination of such materials.
[0015]
A specific method for producing the hot rice cake 4 is as follows.
As shown in FIG. 3A, first, a release agent such as wax is applied to the outer periphery of the core material 100 having a predetermined taper as necessary. Subsequently, the glass fiber prepreg processed into a tape shape or the prepreg 20 in which the reinforcing fibers are skewed in the positive and negative directions is wound around the mandrel 100. The prepreg 20 is formed by winding one sheet around the core material 100 by 1 to 3 turns or sequentially winding different types of prepregs 20.
[0016]
The prepreg 20 in which such reinforcing fibers are skewed in two positive and negative directions can be prepared, for example, by the following method. First, prepare two prepregs in which carbon fibers or glass fibers are oriented in one direction and impregnated with an epoxy resin or the like, and these two prepregs are each in the positive and negative two directions from the axial direction of the casing. A method of obtaining the prepreg 20 by arranging the two sheets in a cross shape so as to be skewed is mentioned. The second method is to obtain the prepreg 20 by impregnating a synthetic resin with a woven fabric in which reinforcing fibers are preliminarily oriented so as to incline in two positive and negative directions from the axial direction of the casing. Further, a prepreg material obtained by impregnating an epoxy resin after reinforcing fibers are woven in two directions so as to be substantially perpendicular to each other is wound around the core material 100 obliquely in the axial direction. Also good.
[0017]
Subsequently, as shown in FIG. 3B, the above-described nonwoven fabric prepreg 21 is wound around the outer periphery of the prepreg 20 wound in this way. Such a nonwoven fabric prepreg 21 is wound about 2 to 5 turns. Also in this case, the nonwoven fabric prepreg 21 processed into a single sheet may be wound, or several different types of nonwoven fabric prepregs 21 may be wound.
[0018]
Further, another prepreg material may be partially wound around the base side end of the nonwoven fabric prepreg 21 by one to several turns. It is wound when necessary to form a fitting part for connecting with the intermediate rod 3.
A protective tape made of polyethylene terephthalate or polypropylene is wound around the outer periphery of the nonwoven fabric prepreg 21 wound in this manner to obtain a bag material. The soot material obtained in this manner is fired in a furnace, the core material 100 is extracted, and the protective tape is peeled off. Then, both ends are cut off to a predetermined length, and the surface is polished.
[0019]
In the spikelet 4 manufactured in this way, the inner layer 10 maintains the minimum required bending / twist strength with respect to the longitudinal direction or twist direction of the spikelet 4. Moreover, the nonwoven fabric layer 11 formed in the outer periphery increases the thickness of the tip heel 4 without excessively increasing the bending strength in the longitudinal direction, and maintains the physical strength necessary for the tip heel 4. In this way, it becomes the tip 4 having good flexibility.
[0020]
[Other Embodiments]
(A) In the above embodiment, a so-called external threaded rod is described in which a fishing line guide 8 is arranged outside each rod. However, this point rod is used for a through rod having a fishing line passage formed inside the rod. Is also possible. In this case, the diameter of the internal space of the cylindrical body necessary for the fishing line to be inserted may be maintained, and a fishing line support protrusion for supporting the fishing line may be formed on the inner surface of the tip rod as necessary.
[0021]
