Description

  The present invention relates to a tip rod for a ship and a method for manufacturing the same.

The performance required for the tip of the tip is that of a very soft tone that keeps a firm tone while waiting for the fish to hit, and once the fish gets caught, it follows the movement of the fish and bends endlessly However, there is a demand.
In general, there are two types of head rods, a hollow cylindrical rod and a solid rod. In the case of a hollow cylindrical frame, it has a high sensitivity surface that conveys fish faith, but in the case of boat fishing etc., the whole point rod is easy to move according to the ship's shaking, and the operation of the mechanism is difficult to do There is.
On the other hand, in the case of a solid rod-shaped pointed tip, when a fish gets caught, it is easy to bend and follow the movement of the fish. , Has the disadvantage of becoming heavy.

  In consideration of such points, conventionally, a hybrid-type spikelet having both characteristics has been provided. In other words, a solid rod-shaped small-diameter tip side rod body is connected and fixed to the tip side of a hollow large-diameter head holding rod body located on the heel side to constitute a tip tip rod (see Patent Document 1). .

JP 2001-238574 A (paragraph number [0011], FIGS. 1 to 3)

However, since the heel side is a solid rod-like body and the heel side is a hollow member, various contrivances have been devised in the connection structure between them. The rigidity of the small-diameter-head-side housing and the large-diameter-head-bearing body so that the rigidity of the small-diameter head-side body and the large-diameter head-holding body are not separated so as to bend as if it is a single material. Is set to a ratio of 6-9 to 10.
If so, the goodness of the solid rod-shaped small-diameter-headed rod body is not fully utilized, it is easily affected by ship swaying, etc., and the small-diameter-headed rod body to the large-diameter-headed rod body bend with a constant curvature. Because it has become easier, the transmission sensitivity of fish faith is also reduced, so there is still room for improvement.

  The object of the present invention is to make it possible to easily perform the mechanism operation without being affected by the shaking of the ship while waiting for the fish to hit and when the propagation of the fish faith is good and the fish is caught. Lies in the point that it provides a sufficient amount of bend and safety.

  The characteristic configuration of the invention according to claim 1 is a solid rod-shaped small-diameter tip side housing located on the tip side and a hollow cylindrical large diameter located on the base side connected and fixed to the small-diameter tip side housing. It has a point that the rigidity of the large-diameter head holding rod is set to 5 to 15 times the rigidity of the small-diameter tip-side rod, and the effect thereof is as follows. Street.

[Action]
Use a hollow cylindrical body as the large-diameter head holding body, and use a solid rod-shaped body as the small-diameter head-side casing, to improve the hollow cylindrical body and the solid rod-shaped body. While maintaining the rigidity of the large-diameter head holding rod with respect to the rigidity of the small-diameter tip-side rod is set to 5 to 15 times larger, the small-diameter tip side rod is low in rigidity, that is, , It will be highly flexible. As a result, even if the ship shakes or the like, the small-diameter tip side skeleton is less likely to follow than a high-rigidity one, and the swaying at the tip of the head is reduced, making it easier to perform the device operation.
In addition, when the fish is caught, the small diameter tip side rod is sufficiently bent and can follow the movement of the fish.

  On the other hand, as in the conventional case, if the rigidity of the small-diameter head side rod body and the large-diameter head holding rod body is not significantly different, and the entire head rod including this connection part shows a large bend with the same curvature, The transmission power of the belief is absorbed by the bending of the ear tip and the transmission becomes worse. On the other hand, the large-diameter head holding rod is configured as a highly rigid cylindrical body, and the rigidity of the small-diameter head side rod and the large-diameter head holding rod is greatly different. When a fish is caught, it will be bent greatly. As a result, since the entire tip of the head does not bend with a constant curvature, the goodness of the transfer characteristics of the fish trust due to the cylindrical body can be maintained.

〔effect〕
The rigidity of the small-diameter-headed rod body and the large-diameter-headed rod body are set to be greatly different from each other, facilitating the operation of the device on the ship, and the fish transmission sensitivity comparable to the pointed rod with only the cylindrical rod body. We were able to provide a hot pot for ship that maintained good quality.

  The characteristic configuration of the invention according to claim 2 resides in that the length of the large-diameter head holding rod relative to the rod length of the small-diameter tip side rod is set to 5 to 15 times the length. The effects are as follows.

[Action]
In other words, because most of the tip of the tip is made up of a large-diameter head with a large rigidity, the tip of the tip is less likely to bend with the same curvature, and the goodness of the fish faith transmission is further improved. Can do.

〔effect〕
As described above, by providing a large difference in rigidity ratio between the small-diameter-head-side rod body and the large-diameter head-side rod body, and a large difference in the rod length, it is possible to provide a head rod for a super-pointing ship. It came to.

〔Constitution〕
The characteristic configuration of the invention according to claim 3 is that a solid rod-shaped small-diameter tip side rod body located on the tip side and a hollow large-diameter pan located on the base side connected and fixed to the small-diameter tip side rod body An inner fitting bulging portion that protrudes inwardly on the inner peripheral surface of the heel tip of the large-diameter head holding rod, and has a tip of the inner fitting bulging portion. A receiving inclined surface that enlarges the inner diameter toward the side and reduces the wall thickness of the large-diameter head holder, and a cylindrical portion having a constant inner diameter or a substantially constant inner diameter on the butt end side of the receiving inclined surface The cylindrical shape is formed on the butt end of the small-diameter head end-side housing at the butt end of the large-diameter head holding pod and on the heel end side of the contact inclined surface. A cylindrical portion having a constant outer diameter or a substantially constant outer diameter that is fitted inside the portion is formed, and the effects thereof are as follows.

[Action]
When the butt end of the small-diameter tip side housing is fitted into the tip of the large-diameter head holding rod, the cylindrical portion of the small-diameter tip side housing fits into the cylindrical portion of the large-diameter head holding rod. . On the other hand, on the tip side, the contact inclined surface of the small-diameter tip side housing contacts the receiving inclined surface of the large-diameter head holding rod. Thus, in a state in which the buttock end of the small-diameter head end side body is fitted and mounted in the heel end of the large-diameter head holding body, contact between the inclined surfaces of the contact inclined surface and the receiving inclined surface, and By contact between the columnar part and the cylindrical part, it is possible to increase the contact area between the small-diameter head side rod body and the large-diameter head holding rod body, and to stabilize the combined state of both.

〔effect〕
As a result, even if it connects the heel end of the small-diameter-head-side skeleton with greatly different rigidity and the heel-tip of the large-diameter heel-holder, Can be suppressed.

〔Constitution〕
A characteristic configuration of the invention according to claim 4 is a method for producing a large-diameter head holding rod body in a tip for a ship according to any one of the inventions according to claims 1 to 3, wherein The outer peripheral surface is hung on the former side and formed into a rod-shaped body whose diameter is increased at a constant rate, and a small-diameter portion whose diameter decreases toward the tip side via a stepped surface is formed at the tip. The prepreg formed by impregnating a reinforcing fiber aligned with a posture inclined with respect to the cocoon axis and the prepreg reinforcing fiber and the cocoon axis are arranged symmetrically and arranged. A main pattern with a length corresponding to the total length along the axial direction of the ridge is wound around the mandrel with a prepreg constructed by impregnating a resin into a reinforcing fiber, and then the reinforcing fiber is aligned in the circumferential direction from above. And impregnated with resin There in that winding the reinforcing pattern length along the direction corresponds to the axial length of the small diameter portion of the mandrel, the effects thereof are as follows.

[Function and effect]
In other words, in order to form the inner fitting bulge portion of the large-diameter head holder, a manufacturing method was shown in which the auxiliary pattern was wound around the core before the main pattern. Since the small diameter portion is formed on the tip side portion of the core metal via the stepped surface, the auxiliary pattern is wound around the small diameter portion so that the outer surface of the wound auxiliary pattern is attached to the intermediate portion of the core metal. It can be formed to have a diameter that is not stepped from the outer diameter.
With such a configuration, even if the main pattern is wound around the outer surface in a state where the auxiliary pattern is wound around the metal core, the swell due to the auxiliary pattern does not occur.
As mentioned above, even if it is to secure the machining allowance by the auxiliary pattern, by remodeling the outer peripheral surface of the core bar, the discomfort caused by the rise can be eliminated, and the small diameter tip side due to the rise There is no need to apply paint to eliminate the level difference between the housing and the large-diameter head.

  The parallel-type or swing-out type ship A will be described. As shown in FIGS. 1 and 2, the boat A is configured by connecting the tip side B on the tip side and the base point C on the tip side in a side-by-side manner. The tip rod B is provided with a fishing line guide 3 such as a top guide and an intermediate guide at the tip of the rod, and as shown in FIG. 1, the tip rod A is composed of a solid rod-like small-diameter tip side rod 1 and its small diameter. It consists of a hollow large-diameter head holding housing 2 connected and fixed to the tip side housing 1. Here, a description will be given on the assumption that the small diameter head side rod body 1 and the large diameter head holding rod body 2 are provided with an external fishing line guide 3.

  As shown in FIG. 1, a blanket 9 has a front grip 10, a trigger-type reel seat 11, and a rear grip 12, which are connected in parallel with the heel end portion of the large-diameter head holder 2. Is attached.

The solid rod-shaped small diameter tip side housing 1 will be described. As shown in FIG. 2 (b), the small diameter tip side rod body 1 is formed in a conical rod shape whose diameter gradually increases along the axis X direction of the rod and is formed near the base end of the rod. A contact inclined surface 1A that decreases in diameter from the maximum large diameter portion a toward the heel end side and a cylindrical columnar portion 1B that further decreases in diameter toward the heel end side are formed. It can be connected to.
The connection between the main fence C and the large-diameter head holding body 2 adopts a side-by-side system, and the front end portion Ca of the main base C is inserted into the heel end 2D of the large-diameter head holding body 2. It is configured to be fitted and connected.

  On the other hand, the hollow large-diameter head holding rod 2 will be described. As shown in FIG. 2 (b), a receiving inclined surface 2B having a diameter decreasing toward the back side is formed at the heel end opening of the large-diameter head holding rod body 2, and further away from the receiving inclined surface 2B. An inner fitting bulging portion 2A is formed toward the inner fitting bulging portion 2A, and a small diameter hole-shaped cylindrical portion is formed by the inner fitting bulging portion 2A. The small-diameter hole-like inner fitting bulging portion 2A is formed only to a certain length, and has a normal thickness on the heel side from the heel side end of the inner fitting bulging portion 2A. A body part 2C is formed.

The manufacturing method of the small diameter tip side housing 1 is as follows. Although not shown in the figure, a bundle of glass reinforcing fibers (500 to 1000) bundled along the axis is submerged in the thermosetting resin liquid and impregnated with the resin, and then pulled out from the die to a predetermined length. Cut to form a solid bar-like member. Here, carbon fiber or the like can be used as the reinforcing fiber, but a glass fiber having a low tensile elastic modulus and high flexibility as compared with carbon fiber or the like is employed.
The tensile modulus of the glass fibers ^{used, 5Ton / mm 2 ~15Ton / mm} 2 can be used.
The reason why the member used at the tip of the spear is in the form of a solid rod is that it is necessary to configure the spear to react sensitively when fish is hung, and it is provided at the tip of the spear In addition, the solid rod shape can be reduced in diameter while being lighter than the hollow rod.

However, if the rigidity is too high, it is not possible to cope with rapid fish pulling and the like, and there is a risk of breakage or cracking. Therefore, it is better to use glass fiber in order to maintain toughness.
Grinding is performed in a conical shape that gradually increases in diameter toward the base side with respect to the outer peripheral surface of the solid rod-shaped member formed as described above, and the base end portion is ground and processed. A contact inclined surface 1A having a smaller diameter and a columnar portion 1B having a constant diameter on the base side are formed.

  A method for manufacturing the hollow large-diameter head-clad housing 2 will be described. First, the shape of the cored bar 4 will be described. As shown in FIG. 3, the rod-shaped material is ground and the outer peripheral surface is formed from the tip side to the base side to form a rod-like body 4B whose diameter is increased at a constant rate, and the tip is stepped. A small-diameter portion 4A that decreases in diameter toward the tip side is formed through the surface 4a.

  The prepreg pattern on the side wound around the cored bar 4 will be described. As shown in FIG. 3, a prepreg 5A constituted by impregnating a carbon fiber (glass fiber) c aligned in a posture inclined with respect to the saddle axis X with a thermosetting resin (thermoplastic resin) and the prepreg 5A A prepreg 5B constituted by impregnating a reinforcing fiber (glass fiber) c and a reinforcing fiber (glass fiber) c arranged symmetrically across the saddle axis X with a thermosetting resin (thermoplastic resin) is used. A main pattern 5 having a length corresponding to the entire length along the axial direction is prepared. Further, a reinforcing pattern 6 is prepared by cutting a prepreg in which carbon fibers c (or glass fibers) are aligned in the circumferential direction to a length shorter than a length corresponding to a ridge.

A fiber having a tensile elastic modulus of 35 Ton / mm ^{2 to} 45 Ton / mm ² is selected as the reinforcing fiber used for the hollow large-diameter head holding rod 2. This tensile elastic modulus belongs to a highly elastic system, and PAN-based carbon fiber, aramid fiber, boron fiber, or the like can be used as the reinforcing fiber.

A hollow large-diameter pancake body 2 is formed from the main pattern 5 and the auxiliary pattern 6 formed as described above. As shown in FIG. 3, the two prepregs 5 </ b> A and 5 </ b> B are wound around the mandrel 4 in a state where the carbon fibers intersect each other. The two prepregs 5A and 5B are also wound around the small-diameter portion 4A of the mandrel 4, and are wound over the entire length of the mandrel 4 of the rod-shaped body 4B from the small-diameter portion 4A. .
The reinforcing pattern 6 is wound at a position corresponding to the small diameter portion 4A of the mandrel 4 in a state where the two prepregs 5A and 5B are wound.

  A prepreg is formed by impregnating a reinforcing fiber c group composed of carbon fibers (or glass fibers) or the like aligned in one direction with a thermosetting resin (or thermoplastic resin) such as epoxy. The main pattern 5 is formed by cutting from the prepreg to a length corresponding to the length of the wrinkles necessary for the large-diameter head holding rod body 2, and the reinforcing pattern 6 is cut from the prepreg to a length shorter than the length corresponding to the wrinkles. Form.

A hollow large-diameter pancake body 2 is formed from the main pattern 5 and the auxiliary pattern 6 formed as described above. As shown in FIG. 3, the direction of the reinforcing fiber c of the auxiliary pattern 6 is aligned in the circumferential direction. The aligned auxiliary pattern 6 is wound around the small diameter portion 4 </ b> A formed on the distal end side of the cored bar 4. In this case, the winding is performed 2 to 3 times (so-called 2 plies to 3 plies). Thereby, sufficient wall thickness can be secured. The winding method may be to cut into a pattern that can cover 3 plies with one auxiliary pattern 6, or a plurality of one-turn patterns may be wound.
In this way, by winding the auxiliary pattern 6 a plurality of times, the small diameter portion 4A of the cored bar 4 is covered and the stepped surface 4a is hidden. That is, there is no step between the surface of the auxiliary pattern 6 wound around the small diameter portion 4A and the outer peripheral surface of the intermediate portion of the cored bar 4.

  After winding the reinforcing pattern 6, although not shown, it is bound with a cellophane tape or the like, and after firing in a firing furnace, the tape is peeled off and cut into a predetermined length. After cutting, it is processed into a predetermined outer shape with a centerless polishing machine or the like. That is, it is formed into a cylindrical body that gradually increases in diameter when hung on the heel side, and a large-diameter head holding rod body 2 is formed by attaching a predetermined paint, fishing line guide 3 and the like.

As shown in FIG. 4 (a), an inner fitting bulging portion 2A obtained by winding the auxiliary pattern 6 is formed on the inner peripheral surface of the heel end of the large-diameter head holding rod 2 by the manufacturing method as described above. The cylindrical portion 1B of the small diameter tip side housing 1 is formed so as to fit inside.
In addition, in order to form a connecting portion with the small diameter tip side housing 1 at the stage of processing into a predetermined outer surface shape by a centerless polishing machine or the like, as shown in FIGS. A receiving inclined surface 2B is formed at the entrance of the inner fitting bulging portion 2A with a simple tool, and the diameter decreases toward the base side.

  As described above, a connecting portion between the small-diameter tip side rod body 1 and the large-diameter head side rod body 2 is formed, and the contact inclined surface 1A of the small-diameter tip side rod body 1 and the columnar portion 1B are connected to each other. The holding body 2 is mounted on the receiving inclined surface 2B and the cylindrical portion. An adhesive is applied to the mounting surface, and the small-diameter tip side housing 1 and the large-diameter head holding housing 2 are bonded and fixed.

  Next, the thread 7 to be fastened and fixed to the connecting portion hardened with an adhesive is wound. As shown in FIG. 5, a tightening thread 7 is wound from the outer peripheral surface of the small-diameter tip side housing 1 to the outer peripheral surface of the large-diameter head holding housing 2. The yarn 7 used here is a non-twisted cotton yarn.

After tightening with the thread 7, the clear coating agent 8 is sprayed and applied onto the thread 7. The enforcement range of the thread 7 is the dimensions of the same lengths b and b along the heel axis direction about the maximum large diameter portion a which is the connection point between the large diameter head holding body 2 and the small diameter head side body 1. It is distributed to.
With the configuration as described above, the tip rod B is formed as a single rod.

As described above, the rigidity ratio between the large-diameter head holding rod body 2 and the small-diameter head-side rod body 1 constituting the head rod B is 5 to 15 times larger in the large-diameter head holding rod body 2. . That is, as described above, the small-diameter tip side housing 1 uses glass fibers having a tensile elastic modulus of 5 Ton / mm ^{2 to} 15 Ton / mm ² , and the large-diameter tip side housing 2 has tensile elasticity. A carbon fiber having a rate of 35 Ton / mm ^{2 to} 45 Ton / mm ² is used.
However, it is desirable that the rigidity EI is 10 times larger in the large-diameter head holding body 2.

The stiffness EI is not determined only by the tensile elastic modulus of the reinforcing fiber, but is determined by the elastic modulus in the state formed in the casing (composite),
Rigidity EI = longitudinal elastic modulus (Young's modulus) of the housing: E × secondary moment of inertia of the housing: I
Determined by.
Therefore, the inguinal diameter related to the cross-sectional secondary moment of the small-diameter tip side housing 1 and the large-diameter head holding housing 2 is set so that the calculated stiffness (EI) becomes the ratio as described above by the above formula. It is necessary to choose.
