BACKGROUND OF THE INVENTION
The present invention relates to a tip rod located closest to the tip of a fishing rod formed by connecting a plurality of rods. In particular, the present invention relates to a tip cocoon in which the tip side portion is a solid body having a small diameter, the heel side portion is formed of a hollow pipe body, and these are bonded to form a single skeleton body.
[0002]
[Prior art]
Some fishing rods used for fishing are used by connecting a plurality of rods as a single fishing rod. Many of the rods constituting such a fishing rod are hollow cylindrical members made of fiber reinforced resin. For example, a certain type of fishing rod can be sequentially housed in a housing on the hand side in a cylindrical form.
[0003]
The tip rod located closest to the tip of such a fishing rod needs to react sensitively when the fish is involved in the device at the tip of the fishing line. For this reason, the spikelet is processed into a small diameter so as to be rich in flexibility and reacts sharply. In addition, in order to process the tip end with a small diameter (particularly, the tip end side of the tip end has a small diameter), the tip end is a solid body and the base end is a hollow pipe body. There is also a type in which both are bonded and fixed together.
[0004]
Specifically, this type of tip end is formed by forming a fitting male part at the base end of the solid body and inserting it into the end end of the pipe body while applying an adhesive. It is fixed. Alternatively, the two are integrally fired and connected and fixed (refer to Patent Document 1 for a method of manufacturing a spike head in which a solid body and a pipe body are connected).

[Problems to be solved by the invention]
In the tip heel formed by connecting such a solid body and a pipe body, the tip side can be sufficiently reduced in diameter by making the tip side a solid body. However, on the other hand, there is a problem that a partial change in rigidity in the axial direction is enlarged due to the connection between the solid body and the pipe body. That is, since the rigidity is different between the solid body and the pipe body, it is difficult to produce the continuous bending of the tip of the head well.
[0007]
In particular, when the solid body is made of glass fiber strong resin in order to increase the flexibility of the tip side of the tip of the head, in order to ensure continuous bending with the pipe body, the pipe body is also made of glass fiber reinforced resin. It is preferable to do this.
However, when viewed in the whole fishing rod, the tip rod is connected to the hollow tip side of the second rod (that is, the pipe body is located on the tip side of the second rod). In many cases, the second basket is made of a carbon fiber reinforced resin for ensuring a certain strength. For this reason, if a pipe body is comprised from glass fiber reinforced resin as mentioned above, it will become difficult to produce the continuous bending between a pipe body and the 2nd well well this time.
[0008]
An object of the present invention is to provide a tip rod that is small in diameter and rich in flexibility, and can produce a continuous bend in the entire fishing rod.
[0010]
[Means for Solving the Problems]
The tip rod of the invention 1 is a tip rod positioned closest to the tip of a fishing rod formed by connecting a plurality of rods. This spike is made of a glass fiber reinforced resin in which a glass fiber is impregnated with a synthetic resin, and is composed of a glass fiber reinforced resin in which a carbon fiber is impregnated with a synthetic resin in a first layer that forms from the tip side end to the heel side end. A hollow member made of resin and having a second layer laminated from the axially intermediate portion of the outer periphery of the first layer to the base side end, and is formed in a cylindrical shape and the tip side end is a receiving part; And a solid member formed of a glass fiber reinforced resin, having a connecting portion that is inserted into the receiving portion and bonded and fixed to the base side end portion, and is formed solid.
The second layer is an outer periphery of the first layer from a position adjacent to the base side of the base side end of the connecting part of the solid member inserted and fixed in the receiving part to the base side end of the hollow member. Are stacked.
[0011]
This hollow member consists only of the first layer made of glass fiber reinforced resin in the tip side portion to which the solid member is connected. Therefore, it is easy to produce a continuous bend with a solid member made of glass fiber reinforced resin.
Only the first layer is present in the receiving part into which the connecting part of the solid member is inserted, and the bending rigidity is suppressed as much as possible in this part. Moreover, glass fiber reinforced resin is made to exist in the overlap part of a solid member and a hollow member, and the continuous bending with a solid member and a hollow member is ensured. On the other hand, the second layer is laminated on the first layer in the portion consisting of only the hollow member without the solid member, and the necessary bending rigidity is produced. Moreover, for example, even if this tip is connected to the tip of the second tip made of carbon fiber reinforced resin, it is easy to produce a continuous bend.
[0012]
The spikelet of the invention 2 is the spikelet of the invention 1, and the second layer becomes thicker toward the root side.
Since the second layer made of carbon fiber reinforced resin becomes thicker toward the base side, the ratio of the second layer to the first layer made of glass fiber reinforced resin increases toward the base side. Therefore, for example, even if this tip end is connected to the tip end of the second end made only of carbon fiber reinforced resin, it is easy to produce a continuous bend.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, the state which mounted | worn with the tip 1 which employ | adopted 1st Embodiment of this invention was attached to the tip side of the 2nd tip 2 is shown. A fishing rod is formed by connecting a plurality of rods to the tip side of a marshal rod (not shown) located on the hand side in a swinging manner or a succession manner. Among such fishing rods, the tip rod 1 is located closest to the tip side, and the second rod 2 is located adjacent to the tip side. For example, when connecting each frame in a side-by-side configuration, the outer peripheral surface of the heel-side end of the tip heel 1 is used as a fitting male part, and this is inserted into the tip-side end of the second heel 2 Fit. In addition, this No. 2 cage | basket is the cylindrical body made from carbon fiber reinforced resin with the taper taper formed by baking the carbon fiber which consists of carbon fiber reinforced resin.
[0014]
(Structure of Hote 1)
As shown in detail in FIG. 1 and FIG. 2, the tip 1 is obtained by connecting two parts to form a single body. That is, the tip 1 is composed of a solid body 10 constituting the tip side and a hollow pipe body 11 constituting the tip side. The solid body 10 is about 10 to 30% of the axial length of the entire tip 1. Further, a fishing line locking tool 3 for tying a fishing line is connected to the end part on the tip side of the point rod 1.
[0015]
The solid body 10 is a rod-like / solid member with a taper that decreases in diameter toward the tip side as a whole. It is formed by pressurizing and heating glass fiber reinforced resin impregnated with synthetic resin after aligning glass fibers in the axial direction. A connecting portion 10a is formed at the base side end of the solid body 10 with a smaller diameter than other portions. The connecting portion 10a has a two-stage structure including a reverse taper portion whose diameter decreases toward the base side and a portion whose diameter does not substantially change in the axial direction on the base side. This portion is inserted into the tip side of the pipe body 11 and fixed to the pipe body 11 with an adhesive or the like. In order to make it easy to apply the adhesive to the connecting portion 10a, grooves may be formed in the connecting portion 10a in the axial direction or the circumferential direction.
[0016]
The pipe body 11 is a tapered cylindrical member provided with a taper that decreases in diameter toward the tip side as a whole. The inner peripheral surface of the end part on the tip side is cut into a predetermined shape and serves as a receiving part for receiving the connecting part 10a. Specifically, the pipe body 11 is formed by laminating and firing two materials. That is, the pipe body 11 is laminated on the first layer 12 made of a glass fiber reinforced resin in which a glass fiber is impregnated with a synthetic resin and the first layer 12 made of a carbon fiber reinforced resin in which a carbon fiber is impregnated with a synthetic resin. And the second layer 13.
[0017]
Among the glass fiber reinforced resins, the first layer 12 is particularly composed of a glass cloth fiber reinforced resin in which glass fibers are skewed in two directions, aligned, crossed, and impregnated with a synthetic resin. It is preferable to use glass fibers with low elasticity as much as possible. The first layer 12 exists in the whole from the tip side end to the base side end of the pipe body 11. As described above, the inner peripheral surface of the tip side end portion of the first layer 12 is cut into a predetermined shape to become a receiving portion, but the glass fiber reinforced resin is relatively easy to polish.
[0018]
On the other hand, the second layer 13 is composed of, among other carbon fiber reinforced resins, carbon fibers that are aligned in the axial direction and impregnated with a synthetic resin. This carbon fiber has a tensile modulus of about 10 to 50 tf / mm 2. As shown in FIG. 2, the second layer 13 is provided on the heel side end portion from a position adjacent to the heel side of the heel side end portion of the connecting portion 10 a of the solid body 10 inserted and fixed in the receiving portion. over, it is stacked on the outer periphery of the first layer 1 2. In particular, the tip side end portion of the second layer may be tapered and inclined so that the tip side becomes smaller in diameter. In addition, the second layer 13 is gradually thickened so as to reach the base side (see FIG. 3 schematically showing the pipe body 11). Smoothed by polishing).
[0019]
The solid body 10 and the pipe body 11 are inserted and fixed to the connecting portion 10a in the receiving portion. Furthermore, as shown in FIG. Etc. are performed. 1 and 2, the paint 14 is shown only at the connecting portion. However, in actuality, the peripheral surface of the entire tip 1 is coated so that the connecting portion between the two is not unclear on the outer shape. Is done.
[0020]
(Manufacturing method of hot tip 1)
Next, the manufacturing method of the spike basket 1 is demonstrated.
The solid body 10 is made by impregnating a predetermined glass fiber with a synthetic resin, and in that state, is drawn to form a glass solid into a columnar shape, and the glass solid is tapered so that the diameter decreases toward the tip side. Further, the base side end portion is shaved to form the connecting portion 10a.
[0021]
The pipe body 11 is manufactured as follows.
First, as shown to Fig.4 (a), the rod-shaped mandrel 100 which gave the predetermined taper is prepared, and the mold release material etc. are apply | coated to the surrounding surface as needed. And glass cloth fiber reinforced resin P1 is wound around the surrounding surface. The glass cloth fiber reinforced resin P1 is wound over the entire axial direction of the mandrel 100, and is wound about 1 to 3 plies in the entire axial direction. Here, although the sheet-like glass cloth fiber reinforced resin P1 is shown, what was processed into the tape shape may be used. By arranging the glass cloth fiber reinforced resin P1 in the cross direction as a whole, the bending, crushing, and twisting rigidity in the axial direction of the entire pipe body 11 is ensured.
[0022]
Next, as shown in FIG. 4B, the carbon fiber reinforced resin P2 is wound around the peripheral surface of the glass cloth fiber reinforced resin P1 wound around the mandrel 100. The carbon fiber reinforced resin P2 is a sheet having a substantially triangular shape in which the winding width on the tip side is set small and the winding width on the base side is set large. In particular, this carbon fiber reinforced resin P2 does not exist up to the tip end portion of the mandrel 100, and exists at the base end portion from a position at a certain distance from the tip end portion. The carbon fiber reinforced resin P2 is wound around the peripheral surface of the glass cloth fiber reinforced resin P1 as shown in FIG. Such a bending rigidity in the axial direction of the carbon fiber reinforced resin P2 pipe body 11 is partially reinforced.
[0023]
Thereafter, if necessary, a protective tape is wound around the outer periphery of these various fiber reinforced resins and fired in a furnace. The mandrel 100 is pulled out, the protective tape is peeled off, the peripheral surface is polished, and the inner peripheral surface of the tip end portion is scraped to make a receiving portion.
Then, the above-mentioned solid body 10 is connected to form one casing, and further, peripheral surface coating or the like is applied to form the tip 1.
[0024]
In such a spike 1, only the first layer 12 of the pipe body 11 is present in the receiving part into which the connecting part 10 a of the solid body 10 is inserted, and the bending rigidity is suppressed as much as possible in this part. It has been. Moreover, glass fiber reinforced resin is made to exist in the overlap part of the solid body 10 and the pipe body 11, and the bending | flexion in the continuous axial direction of both is ensured.
[0025]
On the other hand, in the portion without the solid body 10, the second layer 13 is laminated on the first layer 12 to produce the necessary bending rigidity. Furthermore, in this pipe body 11, since the 2nd layer 13 becomes thicker toward the base side, the ratio of the 2nd layer 13 with respect to the 1st layer 12 which consists of glass fiber reinforced resin becomes large, so that the base side is reached. Therefore, even if this tip end 1 is connected to the tip end of the second end 2 made of carbon fiber reinforced resin, it is possible to produce a continuous bend between the end end 1 and the second end 2.
[0026]
[Other Embodiments]
(A) The modification of the said embodiment is shown in FIG.
The spike head 31 of this modification is also connected to the tip side of the second hook 32. The spike end 31 is obtained by connecting and fixing the solid body 40 on the tip end and the pipe body 41 on the tip side, and is the same as in the above embodiment.
[0027]
The pipe body 41 is formed by laminating and firing two materials. That is, a first layer 42 made of a glass fiber reinforced resin in which a glass fiber is impregnated with a synthetic resin, and a second layer 43 made of a carbon fiber reinforced resin in which a carbon fiber is impregnated with a synthetic resin and laminated on the first layer 42. It consists of. The second layer 43 is laminated on the circumferential surface of the first layer 42 on the heel side from a position about ½ of the axial length of the pipe body 41.
[0028]
The pipe body 41 is obtained by winding a predetermined glass fiber reinforced resin around the entire mandrel in the axial direction, and separately adding a predetermined carbon fiber reinforced resin from a position about ½ of the axial length to the heel side. Are laminated and fired.
(B) In manufacturing the pipe body, first, the glass fiber reinforced resin may be wound around a mandrel and fired, and then the carbon fiber reinforced resin may be partially laminated and fired twice.
[0029]
