Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint type fishing rod using a solid rod. For example, it can be used for a spatula rod, a carp rod, a mooching rod, and a large fishing rod.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 59-20057 discloses a structure in which one kind of a solid rod composed of a reinforcing rod aligned in an axial direction and impregnated with a resin and having a solid shape is used as a tip. Although it has been disclosed that a solid rod is used as a head rod, a hollow rod tube has been used from the hand rod to the ear rod. As for this hand,
The grip portion must be formed larger than a predetermined size to stabilize the fishing operation, and a large bending force acts on the wrist when the fish is caught. This is because the fishing rod must be able to withstand pulling, and the weight must be reduced. If the wand is a hollow large-diameter rod, the middle rod to be spliced to this will also be of a predetermined size. Hollow tubes have been used.

[0003]

However, since the proximal portion is a hollow tube, the more it is bent, the more it receives a strong bending force.
A so-called collapse failure occurs. For this reason, it is configured so as to have a greater bending rigidity so as not to bend significantly near the hand. Therefore, the bending state of the fishing rod when a fish catches is
Although it bends greatly from the middle part to the front part, it does not bend greatly from the middle part to the hand part.Because of the distance from this hand part to the middle part, even if the fish is bent and bent, the angler can grasp it. Since the distance from the hand to the pole tip is long and the bending moment acting on the hand due to the load of fish or the like is large, fishing cannot be said to be light, and furthermore, the large moment makes it easy to break. In addition, since the original rod was a hollow tube, the outer diameter was large, the air resistance was large in the transfer operation, the sharp swing operation could not be performed, and the fishing rod operation was not easy. Therefore, an object of the present invention is to provide a sticky fishing rod that is hard to be broken even when bent greatly from the hand.

[0004]

SUMMARY OF THE INVENTION In view of the above object, a first aspect of the present invention relates to a spliced fishing rod using at least a solid rod as a former rod, wherein a front end of the fishing rod is determined from a diameter of the rod near a grip portion of the former rod. The value obtained by subtracting the rod diameter near the fishing line binding mechanism of the rod or near the top guide is divided by the length between the rods.
Provided is a joint type fishing rod using a solid rod, which is not more than 2/1000. In order to define the taper ratio, the grip part, fishing line binding mechanism part or top guide part is removed to remove the locally uneven part before and after the fishing rod, near the grip part of the original rod and at the tip of the head If there is any other locally uneven portion near the tip of, the diameter is measured excluding it.

According to a second aspect of the present invention, a plurality of rods each consisting of a solid rod are joined, and the original rod has a diameter from the rod near the grip portion to the diameter near the original rod joint. Divide the subtracted value by the length in between, and subtract the value obtained by subtracting the rod diameter near the fishing line binding mechanism of the head rod or near the top guide from the rod diameter near the joint. Divide by length,
For the middle rod, the value obtained by subtracting the rod diameter near the front joint from the rod diameter near the joint at the rear is divided by the length in between,
The present invention provides a spliced fishing rod using a solid rod in which the respective taper ratios obtained in this manner gradually decrease from the head to the former. The diameter of the taper at this point is measured at a portion excluding a local uneven portion as in the first embodiment. In addition, the taper ratio is considered to be positive or negative, and the taper ratio of a negative value is naturally smaller than the positive value. The taper rate at which the taper tapers is a positive value.

According to a third aspect of the present invention, there is provided a spliced fishing rod using a solid rod as a former rod, wherein an outer diameter of a leading end of a spliced portion of the former rod is
A spliced fishing rod using a solid rod, wherein the diameter is larger than the diameter near the grip, and the diameter near the grip is larger than the diameter near the joint of the original rod. In claim 4, the difference between the diameter near the joint of claim 3 and the diameter near the rear joint of the first middle rod, which is a solid rod directly joined to the original rod, is less than 1 mm. In addition, the vicinity of the joint portion of the original rod and the vicinity of the rear joint portion of the first middle rod are configured to mainly use the same type of reinforcing fiber. The reinforcing fiber is not limited to one type, and two or more types (for example, carbon fiber and glass fiber) may be used at each location. The same kind is a carbon fiber if it is a carbon fiber, and a difference between elastic modulus of about 15 ton / mm ² or less is preferable.

According to the first aspect of the present invention, the hand is thinner than a conventional fishing rod in which the original rod is a hollow tube. However, since the original rod is a solid rod, it is difficult to be crushed and broken even if it is greatly bent. It becomes a sticky fishing rod. According to the second aspect, the hand is relatively thinner than a fishing rod having the same taper ratio as the head rod, but it is hard to be crushed even if it is greatly bent because it is a solid rod, and it is hard to break and stick. It becomes a fishing rod with. In the third aspect, except for the joint portion, since the original rod has a tapered shape as a whole, the original rod strength against fishing load is high, and since the diameter of the joint portion is large, the first middle rod to be spliced thereto. Need not be suddenly reduced in diameter as compared to the original rod, the thickness of the original rod and the first middle rod is balanced, stress concentration is prevented, and the fishing rod is hard to break and sticky. According to the fourth aspect, the bending rigidity before and after the joint portion between the former rod and the first middle rod is continuous, the strength is balanced, and the fishing rod is harder to break and more sticky.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 shows a joint type fishing rod according to the present invention, which includes a former rod 10, a first middle rod 12, and a second rod.
Four rods, a middle rod 14 and a tip rod 16, are joined in parallel. Unless otherwise specified below, the number of poles is arbitrary. Each rod is a solid rod made of a fiber reinforced resin (FRP or FRTP) obtained by reinforcing a resin matrix such as an epoxy resin with a reinforcing fiber such as carbon fiber. It is formed by reinforcing resin with carbon fiber.

At the distal end of the original rod 10, a joint 10T having a hollow portion for receiving the rear joint of the first middle rod 12 is formed. 2 Nakapole 1
4, a joint 12 having a hollow portion for receiving a rear joint
T is formed, and a joining portion 14 having a hollow portion for receiving a joining portion of the spike rod 16 is provided at the distal end of the second middle rod 14.
T is formed. Further, a grip portion 20 made of natural cork or Jura cork (trade name) is formed at the rear of the former rod, and a fishing line binding mechanism having a fishing line binding section 18 is provided at the tip of the tip rod 16. A fishing line is tied to the fishing line here for fishing. If the fishing rod is of a type that mounts a reel, it has a top guide portion instead of the fishing line binding mechanism portion. Reference numeral 22 is a buttock.

First, claim 1 will be described using this example. From the rod diameter D8 immediately before the grip portion 20 of the former rod 10, the rod diameter D1 immediately after the fishing line binding mechanism of the head rod 16
Is subtracted and divided by these distances L0 (D8-D
1) The taper ratio determined by / L0 is 2.2 / 1000 or less, preferably 2.0 / 1000 to 0.5 / 1000, and more preferably 1.8 / 1000 to 1.0 / 10.
00. This fishing rod configuration has a small taper ratio and the whole fishing rod is elongated. The original rod is relatively thin compared to a fishing rod that is a hollow rod tube, but since each rod such as the original rod is a solid rod,
Even if it flexes greatly to the hand, it is hard to break, it is hard to break and it becomes a sticky fishing rod. In order to prevent lifting, the entire length is preferably 5 m or less, preferably 4 m or less.

Next, claim 2 will be described. Hereinafter, the taper rates T1, T2, T3, and T4 of the head rod 16, the second middle rod 14, the first middle rod 12, and the original rod 10 will be described in order. T1 = (D2−D1) / L1 T2 = (D4−D3) / L2 T3 = (D6−D5) / L3 T4 = (D8−D7) / L4 However, as shown in the drawing, immediately before the joint portion of the tip rod. The diameter of the rod is D2, the diameter of the rod immediately after the front joint 14T of the second middle rod is D3, the diameter of the rod immediately before the rear joint is D4, and the front of the third intermediate rod is joined. Immediately after the portion 12T, the rod diameter is D5,
The diameter of the rod immediately before the rear joint is D6, and the joint 1 of the original rod is used.
The rod diameter immediately after OT is D7, and the rod diameter immediately before the grip is D8. L1, L2, L3, and L4 are the distances between the diameter portions of each rod.

Since T1>T2>T3> T4, the hand is relatively thinner than a fishing rod having the same taper ratio as the head rod, but each rod including the original rod is medium. Since it is made of an actual rod, it is hard to be crushed even if it is greatly bent, and it is hard to break and it is a sticky fishing rod.

Next, claim 3 will be described. The outer diameter D67 of the distal end of the joint 10T of the former rod is larger than the diameter D8 of the rod just in front of the grip portion 20, and the diameter D8 is equal to the diameter of the joint 10.
It is larger than the rod diameter D7 immediately after T. Thus, the joint portion and the grip portion 20 are removed, but the original rod has a tapered shape as a whole, so that the original rod strength against fishing load is strong, and since the joint portion diameter is large, the first joint to be joined thereto is The inner rod does not need to be suddenly configured to be smaller in diameter than the original rod, and the thickness of the former rod and the first intermediate rod is balanced to prevent stress concentration, resulting in a fishing rod that is hard to break and sticky.

Next, a description will be given of claim 4. The above diameter D
7 is smaller than the diameter D6 just before the rear joint portion of the first middle rod 12 by less than 1 mm, is formed to have almost the same diameter, and both the original rod and the first middle rod are made of the same type of carbon. Since fibers are mainly used, the bending rigidity between the original rod and the first middle rod does not change abruptly except for the joint portion 10T in a state where the rods are joined together. The middle pole is continuous. The rigidity of the joint between the former rod and the first middle rod is higher than before and after, but the range of high rigidity is narrow, and no stress concentration occurs before and after bending. Therefore, the rigidity is balanced so that stress concentration is prevented, and the fishing rod is hard to be broken and sticky. Preferably, the diameter difference is 0.65 mm
Less than.

In the embodiment shown in FIG. 1, each joint 10T,
The diameter of each of the front and rear rod regions is smaller than the outer diameters D67, D45, and D23 of 12T and 14T, and the difference between these front and rear diameters is small, and the difference is less than 1 mm. .
Furthermore, what is larger than the rod diameter in the front and rear regions may be not all the joints but a part thereof. For example, as in the case where the rod 14 is a hollow rod tube, the diameter D of the joint 14T
23 may be formed so that the rod diameter D3 immediately after it is larger. The reason why the joint portion is larger than the front and rear rods is because of joining, and it is inevitable that it is smaller than this joint portion. This is possible by making the region a solid rod, thus improving the deflection balance between the front and rear regions. The number of joints is also arbitrary.
To 4 can be arbitrarily combined.

The material of the joints 10T, 12T, 14T is
If a material having a higher strength is used than the main body portion excluding the joints of the rods 10, 12, and 14, or if the ratio of the high-strength material is increased, a load such as a fish may act. Therefore, the strength against the force acting due to the joining is improved, and the strength of the entire rod including the joint and the rod main body can be efficiently improved without waste. The number of joints is also arbitrary,
Such a configuration can be arbitrarily combined with the configuration in the above section 0015 or the configuration of claims 1 to 4.

Each of the solid rods 10, 12, 14, 16 has a solid rod structure in which a core material is ground (usually formed into a tapered shape) and a fiber reinforced resin prepreg is wound around the outside thereof. Further, peeling and breakage from the cut fiber end exposed on the core material surface can be prevented, and the strength of the solid rod is improved. Since a larger bending moment acts on the base portion, the strength is improved by increasing the prepreg winding amount in the base portion of the solid rod. In addition, if the high elastic fiber of the wound prepreg is increased as the base portion is increased, the strength of the solid rod can be improved by countering a large bending moment, and the amount of prepreg required to obtain a desired bending rigidity is reduced. It is possible to make it smaller, and the swing is sharper and easier to handle. Again, the number of joints is arbitrary, and the double structure of the solid rod can be applied to any rod. Such a configuration is the same as the configuration in the above section 0015 or 001.
It can be arbitrarily combined with the configuration of the sixth column and the configurations of claims 1 to 4.

In the case of reverse joining in which a cylindrical joint is formed at the rear end of the first middle rod, and the tip of the original rod is inserted into the joint, the diameter of the first middle rod is equal to D6. Part diameter D6 '
Is generally larger than the diameter D7 'of the diameter D7 portion of the original rod, but even in this case, D6'-D7' is 1
mm, preferably less than 0.65 mm.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The outer diameter of the front joint 12T of the first middle rod 12 in FIG.
Is set to D23, and the diameter (mm) of each part is illustrated. D1 = 0.98 D2 = 2.68 D3 = 3.04 D4 = 4.31 D5 = 4.64 D6 = 5.73 D7 = 6.25 D8 = 6.57 D23 = 3.43 D45 = 5.32 D67 = 7.20 Each length excluding the rear joint part (the original rod is the gripping part) of each rod is 650, 650, 700, 60 in order from the tip rod.
0.

Each joint 10T, 12T, 14T of the parallel type
Both the outside diameter and the inside diameter are set to a tapered shape (reverse taper), and the thickness difference between the front end and the rear end is set to 25% or less, preferably 20% or less. In the case of the reverse joint type, the magnitudes before and after the joint portion may be considered to be reversed.

With respect to the length of each of the fishing rods, it has been general that the length of the original rod is made the longest and the length of the rod is made shorter (including the same length) up to the tip of the head. However, this makes it easy to become a pretending pole. It is easy to construct the body condition even if the head rod is made the longest and each rod is shortened sequentially up to the original rod, or the head rod is lengthened, each middle rod is shortened, and the original rod is lengthened. If such a large flexure area is constituted by a solid rod, it is difficult to tear, so that the strength is high and large flexure is possible.

In order to make the operation of the fishing rod mainly by swinging more comfortable than before, there are the following configurations. Further, the following configuration may be combined with each of the above-described configurations of claims 1 to 4. In the embodiment of the first aspect of the present invention, the position of the center of gravity of the fishing rod can be configured so as to be within 1/3 of the entire length of the fishing rod from the original side. (Structure 1) At least four or more spliced fishing rods using a solid rod as a former rod, and the center of gravity of the fishing rod in a state where all the rods are spliced is within the length range of the former rod, or When the reinforcing layer is present at the rear portion of the first middle rod immediately before the former rod, if it is configured to be present within the range of the reinforcing layer, the fishing rod operation such as bait driving or the rod transfer operation becomes comfortable, Like rods and bamboo rods made of fiber reinforced synthetic resin and made of conventional hollow pipes, each rod has a greater weight than a hollow pipe. There is no weight.
The reinforcing layer is not a prepreg winding layer that extends over substantially the entire length of the first middle rod, but a layer that reinforces only the vicinity of the rear joint.

As a method of adjusting the weight, the specific gravity of each rod is changed by changing the type of the reinforcing fiber or the synthetic resin of the fiber-reinforced synthetic resin material forming each rod, and the rod is formed of a material having a lighter specific gravity as the tip rod. It is made of a material having a specific gravity heavier than the original rod. That is,
In the case of a solid rod, the specific gravity of the core material serving as the core, or, if there is a prepreg wound around the core material, the specific gravity of the prepreg, or the specific gravity of both of them is changed. As the reinforcing fibers, there are organic fibers, carbon fibers, glass fibers, metal fibers, ceramic fibers, and boron fibers. The weight may be adjusted by other methods, but the weight of the rod body is changed. This weight adjustment method is the same for each of the following (configuration X).

(Structure 2) Four or more spliced fishing rods using at least a solid rod as a former rod, wherein the rods are sequentially numbered 1st, 2nd and 3rd from the tip to the rear. Assuming that the pole is the fourth pole, the weight of the second pole is at least three times that of the first pole, the weight of the third pole is at least twice that of the second pole, and the fourth pole is 1.5 times the third pole. As described above, when the center of gravity of the fishing rod in a state where all the rods are joined is present within one third of the hand side of the entire length of the fishing rod, the swing is balanced and the operation of the fishing rod becomes comfortable. (Structure 3) At least a three-joint type fishing rod using a solid rod as the original rod, wherein the rods are sequentially numbered first, second, and third from the tip to the rear, The weight of the No. 2 rod is at least three times that of the No. 1 rod, the weight of the No. 3 rod is at least twice the weight of the No. 2 rod, and the center of gravity of the fishing rod with all the rods joined is near the entire length of the fishing rod. If it is configured to exist within 1/3, the swing is balanced and the operation of the fishing rod becomes comfortable.

In the case where the above configuration 2 is a four-piece fishing rod, an embodiment will be described with reference to FIG. Head rod 16, 2nd middle rod 1
4. The total length (mm) of each rod of the first middle rod 12 and the former rod 10
ZL1, ZL2, ZL3, ZL4 and the weight (g) of each rod as W1, W2, W3, W4 are as follows. ZL1 = 685 ZL2 = 695 ZL3 = 760 ZL4 = 760 W1 = 3.0 W2 = 10.0 W3 = 22.5 W4 = 44.4 (The weight of the grip member of the grip portion 20 is about 10 g) The length of the rod is not significantly different, and the shortest rod is a joint type fishing rod having a length of 2/3 or more of the longest rod. is there. In this case, the total length of the fishing rod obtained by joining the rods is about 2700 mm, and the center of gravity of the fishing rod is located at about 750 mm from the original end, so that the swing is balanced and the fishing rod operation becomes comfortable.

[0026]
