Description

  The present invention relates to a fishing rod rod body having a tubular shape and a fishing rod having a plurality of fishing rod rods.

The fishing rod housing has a cylindrical shape, and is generally formed by winding a prepreg around a rod-shaped mandrel that gradually increases in outer diameter along the axial direction. The prepreg is obtained by cutting a prepreg formed by impregnating a reinforced fiber such as carbon fiber in one direction with a matrix resin such as a thermosetting resin into a predetermined shape.
A plurality of such prepregs are wound around a mandrel over a plurality of layers, or a single prepreg is wound around a plurality of plies to form a cylindrical body and fired in a state of being wound around the mandrel. After firing, the mandrel is decentered and cut into a predetermined length to produce a casing.
JP 2006-320235 A (paragraph [0016], FIG. 1)

In the structure described above, it is configured in a cylindrical shape whose inner and outer diameters are slightly increased along the axial direction, and a single carbon fiber group and a single thermosetting are included in the casing. Resin etc. are used.
A fishing rod that is connected from a tip rod to a marshal rod composed of a single carbon fiber group, a single thermosetting resin, etc., shows a change in rigidity against displacement. Until the displacement occurs, the rigidity value increases with a substantially constant rate of change, but in a certain region where the constant displacement occurs, the amount of change in stiffness (rate of change) increases rapidly relative to the amount of change in displacement. It is inferred that there is a tendency.
Here, the rigidity is defined as longitudinal elastic modulus (E) × secondary moment of inertia (I).

  Then, when the fish catches the needle and the displacement of the fishing rod reaches the above-mentioned fixed region, when the angler performs the operation of lifting the fishing rod and floating the fish, the amount that the fishing rod lifts is small. Even if it exists, since rigidity will increase rapidly, a large operating force corresponding to the rapid expansion of the rigidity is required, and a large load will also act on the fish caught by the needle.

  An object of the present invention is to provide a fishing rod capable of performing quaint fishing that can be exchanged with a supple and sticky fish by introducing a tubular body made of a material other than a prepreg in the fishing rod body. In the point.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is that the heel side portion and the heel side portion are connected by an intermediate portion, and the heel side portion is pulled in one direction along the axis of the housing. It is composed of a prepreg having aligned reinforcing fiber groups, and the base portion is composed of a prepreg having reinforcing fiber groups aligned in one direction along the saddle axis of the casing, and the intermediate portion is It is in the point comprised with the cylindrical body made from bamboo, The effect is as follows.

[Action]
A bamboo rod body that is different from the prepreg in the middle is used to construct a fishing rod rod. Was combined with a prepreg heel side portion and heel side portion.
Then, the characteristics of a fishing rod body that connects the tip side portion, the intermediate portion, and the base side portion, and the characteristics of a fishing rod that connects other rod bodies are as follows. In other words, in this fishing rod, the properties of the bamboo cylinder constituting the intermediate portion affect the properties of the entire fishing rod, and the properties of the intermediate portion are reflected as they are, and even in a certain region where a certain displacement occurs, it is substantially constant. It is a highly flexible fishing rod that increases the rigidity value with a change rate of.
Then, when the fish catches the needle and the fishing rod is displaced to reach a certain area, even if a force acts on the fishing rod slightly from that state, the fishing rod absorbs the force by its flexibility and displaces. Does not produce much and does not exert a strong load on the fish.

On the other hand, in the fishing rod according to the present invention, when the fishing rod is lifted upward and the fish is floated from the state where the displacement reaching the certain region causing the certain displacement acts, the rigidity in the conventional configuration is, for example, Unlike the case where a large operating force is required to give a slight displacement as in the case of a sudden increase, the fishing rod can be lifted with a small operating force, and the influence on the fish can be suppressed.
In the present invention, when a fish is caught and a displacement exceeding the above-mentioned fixed displacement is caused, the fishing rod has its own little change in rigidity even if the angler applies little force or little force. Taking advantage of flexibility, lift the tip of the tip and lift the fish.
The fish that can be floated is not subjected to a heavy load because the tip of the fish just lifts up.
This is possible because of the introduction of bamboo cylinders. This is because the longitudinal elastic modulus of bamboo is unknown, but is considered to be smaller than that of prepreg.

〔effect〕
In this way, it was possible to provide a fishing rod rod body capable of performing quaint fishing that can be exchanged with a supple and sticky fish simply by introducing a cylindrical tube made of bamboo at the intermediate portion.

〔Constitution〕
The characteristic configuration of the invention according to claim 2 is that the outer diameter of the bamboo tubular body is configured to be larger than the outer diameter of the heel side portion and the outer diameter of the heel side portion. There are the following effects.

[Action]
The longitudinal elastic modulus of the used material is different between the heel side portion and the heel side portion and the intermediate portion located in the middle thereof. Therefore, when the same outer diameter is set, the difference in rigidity (longitudinal elastic modulus × secondary moment of section) is too large, and there is a surface in which the entire fishing rod is difficult to bend smoothly.
On the other hand, by increasing the outer diameter of the bamboo cylindrical body, the cross-sectional secondary moment is made larger than the cross-sectional secondary moment of the heel side portion and the heel side portion, and the difference in rigidity is required. It is suppressed to.

〔Constitution〕
The characteristic configuration of the invention according to claim 3 is that the fishing rod rod body having the intermediate portion is a marine rod, and the operation and effect thereof are as follows.

[Function and effect]
Since the Marshal is the starting point of the bend when the fish is caught, you can get a large deflection near the angler's hand and stretch the arm holding the fishing rod against the fish pull etc. It is possible to construct a fishing rod that can withstand

〔Constitution〕
The characteristic configuration of the invention according to claim 4 is that the fishing rod rod body having the intermediate portion is a middle rod, and the effects thereof are as follows.

[Function and effect]
In other words, since the middle part with high flexibility is provided in the middle, compared with the case where it is provided on the main fence, the starting point of the bend can be moved slightly to the tip side, compared with the case where it is provided on the former. The bending when the fish is caught can be suppressed, and the lifting force when the fish is caught can be increased.
However, when a high-flexibility intermediate part is provided on the main fence and the middle eaves, it is possible to provide bending starting points at a plurality of locations, compared to the case where the intermediate part is provided only on the main eaves or the intermediate eaves. It was possible to construct a fishing rod that bends greatly in steps, making it easier to respond freely to fish movement.

[First Embodiment]
A configuration of the fishing rod A such as a spatula rod will be described. As shown in FIG. 1, a fishing rod A includes a tip rod 1 having a fishing line locking member 1A attached to the tip of the rod, and a second rod 2A, three connected to the tip rod 1 in a side-by-side manner. It is configured to be equipped with a center rod 2 such as a number 2B and a main rod 3 connected in a cascade manner to the number 3B 2B.

  The configuration of the main fence 3 will be described. As shown in FIGS. 1 and 2, the rivet 3 includes a tubular heel side portion 3B, a cylindrical heel side portion 3C having a grip 4 at the heel end, and a heel side portion 3B. An intermediate part 3A arranged between the base part 3C and the base part 3C is connected and fixed.

  The heel side portion 3B and the heel side portion 3C are manufactured as follows. In other words, although not shown, a prepreg formed by impregnating a thermosetting resin such as epoxy into a reinforcing fiber group such as carbon fiber aligned along the radial axis direction or the circumferential direction has a predetermined shape. The main pattern and the auxiliary pattern thus cut are wound around a rod-shaped mandrel with a tapered surface to form a bag material, fired together with the mandrel, and after firing, the mandrel is decentered, Cut to a predetermined length to form the heel side portion 3B and the heel side portion 3C.

When the intermediate portion 3A is formed, the bamboo material is cut and used. Bamboo called as bamboo, Takano bamboo, Yatake can be used as the bamboo material.
The parallel connection structure of the tip side portion 3B and the intermediate portion 3A will be described. As shown in FIG. 2A, a taper fitting surface 3b having a smaller diameter toward the buttock end side is formed at the buttock end portion of the outer peripheral surface of the heel side portion 3B. On the other hand, a tapered outer fitting surface 3a is formed at the end of the inner peripheral surface of the intermediate portion 3A.

  As shown in FIG. 2B, the taper inner fitting surface 3b of the tip side portion 3B is fitted into the taper outer fitting surface 3a of the intermediate portion 3A, thereby connecting the two. An adhesive is applied to the connection surface between the taper outer fitting surface 3a and the taper inner fitting surface 3b to strengthen the bonding, and the heel end surface 3d of the intermediate portion 3A and the heel end portion of the heel side portion 3B A reinforcing portion 3f is formed by applying a resin material to a step portion formed between the outer peripheral surface 3e and the outer peripheral surface 3e.

  As shown in FIG. 2 (b), the taper inner fitting surface 3c of the collar side portion 3C is fitted into the taper outer fitting surface 3a of the intermediate portion 3A, thereby connecting the two. An adhesive is applied to the connection surface between the taper outer fitting surface 3a and the taper inner fitting surface 3c to strengthen the connection, and the flange end surface 3g of the intermediate portion 3A and the flange tip portion of the flange side portion 3C are connected. A reinforcing portion 3f is formed by applying a resin material to a step portion formed between the outer peripheral surface 3h.

  With the configuration as described above, the rate of change in rigidity in the state where the constant displacement has occurred in the intermediate portion 3A, the rate of change in stiffness in the state in which the constant displacement has occurred in the tip side portion 3B, and the It is assumed that the rate of change in rigidity is smaller than that in the state where the constant displacement is generated in the heel side portion 3C.

Then, the nature of the fishing rod A connecting the rod-side portion 3B, the intermediate portion 3A, and the rod-side portion 3C, or the fishing rod A connecting other rods, is as follows. That is, as shown in FIG. 6A, in this fishing rod A, the properties of the intermediate portion 3A affect the properties of the entire fishing rod, and the properties of the intermediate portion 3A are reflected as they are, so that a certain region in which a certain displacement occurs. Even if a displacement occurs beyond the range, the fishing rod A is highly flexible and has a substantially constant rate of change and the rigidity value increases.
Then, as described in the section of the effect, it is possible to obtain a fishing rod A that is less likely to give a shock to the fish and is easy to handle and easy to lift.

  In the above description, the mode in which the intermediate portion 3A is provided on the main rod 3 has been described, but it may be provided on the intermediate rod 2 or the like as follows. That is, as shown in FIG. 3A, the intermediate portion 2C described above is formed only on the third cage 2B. Compared with the case where the intermediate portion 3A is provided on the main rod 3, a portion that is slightly deformed moves to the tip side, and the deflection of the fishing rod as a whole is somewhat suppressed.

As shown in FIG. 3B, the intermediate portion 2D is formed only on the second rod 2A. Compared with the case where the intermediate portion 2C is provided on the third rod 2B, the portion that is slightly deformed further moves toward the rod tip side, and the deflection of the fishing rod as a whole is further suppressed.
As shown in FIG. 3C, the intermediate portions 3A and 2C described above are formed on both the main fence 3 and the third fence 2B. In this case, the main rod 3 and the third rod 2B are provided with easily deformable portions, so that the fishing rod as a whole is easily bent as compared with the case where only the main rod 3 is provided.

  As shown in FIG. 3 (d), the intermediate portions 3A and 2D described above are formed on both the main rod 3 and the second rod 2A. In this case, since the main rod 3 and the second rod 2B are provided with easily deformable portions, the fishing rod as a whole is more flexible than the case where only the main rod 3 or the main rod 3 and the third rod 2B are provided. And if the pull of the fish becomes strong, not only the second salmon 2B but also the marshal 3 will bend, and it will be easy to make a bean.

  As shown in FIG. 3 (e), the intermediate portions 2C and 2D described above are formed on both the third cage 2B and the second cage 2A. In this case, since the third rod 2B and the second rod 2C are provided with easily deformable portions, the intermediate position of the fishing rod as a whole compared to the case where only the main rod 3 or the main rod 3 and the third rod 2B are provided. It was easy to bend, and it was able to be a fishing rod that could smoothly convey the fish's pulling force to the hand grip without bending the curve of the curve at the apex position.

As shown in FIG. 3 (f), the intermediate portions 3A, 2C, and 2D described above are formed on the three sides of the main fence 3, the third fence 2B, and the second fence 2A. In this case, since a portion that is easily bent is formed in the rod body other than the tip rod 1, the fishing rod as a whole can be easily bent, and a fishing rod that can follow the movement of the hooked fish as much as possible can be configured. It was.
With the above configuration, as the fishing rod body, the tip side portion and the heel side portion are configured to be relatively difficult to bend. Therefore, when the fish is not hung, the tip rod 1 to the main rod 3 are linear. While maintaining good shape retention, it was possible to obtain a fishing rod that exhibited sufficient flexibility when fish caught.
