Description

  The present invention relates to a joint type fishing rod using a solid rod.

  Conventionally, fishing rods using a hollow rod tube have been the mainstream except for the tip rod, but at sites where a large bending force can act, such as a marine rod, the rod tube is hollow, causing collapse and fracture. There was a thing.

In order to prevent this, it is considered to use a solid rice cake other than the head rice cake. A solid rod is smaller than a hollow rod tube if it has the same bending rigidity on the premise that the same material is used. Therefore, there is a surface with characteristics different from those of fishing rods that mainly use hollow rods, and these can be used effectively as fishing rods. Is required.
Accordingly, an object of the present invention is to improve the operability of seaming work and the operability of fishing due to the structure of the joint portion.

The invention according to claim 1 is a fiber-reinforced resin joint type fishing rod having a tip rod, at least one middle rod, and a marine rod, and two continuous rods in a joined state There are two or more joining parts that are heels, and the joining fitting surface of each joining part has a taper shape whose diameter expands forward or backward, and the taper rate of each joining part is that of the front joining part Provided is a joint type fishing rod using a solid rod characterized by being smaller than the joint portion on the side.
The taper shape includes a straight and the taper rate is considered as a positive value. The rear thin taper (parallel connection) is set to a positive value and the front thin taper (reverse connection) is set to a negative value.
The fact that the front side is smaller than the rear side includes the same case as described in the following paragraph.

  In fishing, the fishing rod bends with the fish hooked, but the part close to the tip of the hook hangs downward, and generally the part close to the base of the hook is diagonally upward, so the joint part near the tip of the hook is The taper ratio of the mating surface is reduced to make it difficult to pull out, and it is unlikely that the joint part close to the base will come off from that direction. In order to prevent the joining portion from sticking, the taper rate is made larger than the tip side (front side). However, the same degree is included. While the taper rate of the front joining site is smaller than the taper rate of the rear joining site, the meaning of including the same value is, for example, that there are 4 joining sites, Two are small taper ratios of the same degree, and the two parts on the original side may have the same large taper ratio. Therefore, if the taper ratio on the front side is used as a reference, the principle is that the taper rate increases toward the rear side, but the case where there is the same value and increases stepwise is also included. Further, the same taper ratio is ignored, and the same degree is considered.

Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIG. 1 is a joint type fishing rod according to the present invention, and FIG. 2 is an exploded view thereof. Four hollow rods, a first rod 12 of the hollow rod tube, a second middle rod 14 of the solid rod, and a tip rod 16 of the solid rod are joined together in a side-by-side manner. Unless otherwise specified below, there is no limit to the number of powers. In addition, each ridge is made of a fiber reinforced resin (FRP or FRTP) in which a matrix of a resin such as an epoxy resin is reinforced with a reinforced fiber such as a carbon fiber. Reinforcement formation using as the subject. In addition, each ridge has a layer of reinforcing fibers generally oriented in the axial length direction.

  A joint portion 10T having a hollow portion for receiving the rear joint portion 12t of the first center collar 12 is formed at the front end portion of the main collar 10, and the second middle portion is formed at the front end portion of the first center collar 12. A joint portion 12T having a hollow portion for receiving the rear joint portion 14t of the collar 14 is formed, and a joint having a hollow portion for receiving the joint portion 16t of the tip collar 16 is formed at the tip of the second middle collar 14. A joint portion 14T is formed. Furthermore, a grip 10G made of natural cork or Jura cork (trade name) is formed at the rear of the marshall, and a tail plug S is bonded to the rear end. A fishing line binding portion 16K is provided at the tip of the head rod 16, and fishing is performed by connecting a fishing line to the tip portion.

  Since the tip 16 and the second middle cocoon (that is, the hochi cocoon) 14 are solid cocoons, the diameter is reduced compared with the case where these are hollow tubs. In this case, the air resistance is small and the swing operation becomes light. Further, when fishing is performed with the tip of the rod submerged in the water like a funnel, the underwater resistance is reduced. Therefore, draining is easy and quick dredging operation is possible.

  In this case, since the first center rod 12 and the main rod 10 are hollow rod tubes, the head rod 16 can be stored in the first center rod 12, and the head rod 14 can be stored in the main rod 10, and can be carried. Convenient. In addition, it is easy to form irregularities such as golf ball dimples on the surface of the solid spike and spike holder, which makes it easier to follow the tip when swinging very quickly. . In addition, since the head rod and hochi rod were solidly formed, compared to the hollow rod tube with the same bending rigidity as these, it was possible to make a fishing rod with stickiness and power while having the same swing tone. The fish can be easily pulled up to the surface of the water, and the time to fish uptake can be reduced.

  In the above-described embodiment, each ridge has a layer mainly composed of reinforcing fibers oriented in the axial length direction, and the main fence and the first middle ridge are hollow ridge pipes. The outer diameter is large compared to the case of a solid bowl having rigidity. The presence of reinforcing fibers oriented mainly in the axial length direction that contributes to flexural rigidity is also a resistance against torsion, which increases the torsional rigidity of hollow steel pipes with an outer diameter larger than that of solid steel. It is difficult to twist, can prevent the body from shaking during the operation of the fishing rod, and easy to operate.

  Furthermore, in order to improve the torsional rigidity, a layer in which the reinforcing fibers intersect the 45 ° direction and the −45 ° direction with respect to the axial length direction is provided on the outermost side of each of the flanges 10, 12, and 14 as much as possible. The torsional rigidity is most effectively improved. Even if it is not 45 degrees, it is effective to some extent if it is set in the range of 30 to 60 degrees, and in the widest range, it is in the range of 15 to 75 degrees. In any case, a high-quality fishing rod is provided by crossing the same amount of fibers with the same elastic modulus from the left and right directions at the same inclination angle so that the torsional rigidity is as symmetric as possible with respect to the axial direction. It leads to.

As a specific manufacturing method, knitting from the left and right directions by braiding, using a woven fabric, or winding (stacking) an alignment sheet or alignment tape from both directions so that the fibers intersect. The tip 16 does not significantly affect the swing of the fishing rod operation, so no countermeasures against twisting are taken, and a circumferential fiber layer is provided on the outer periphery of the solid core portion mainly composed of the axial length fiber.
In contrast to the above, the device for improving the torsional rigidity is the same when the base rod and the first center rod are formed as solid rods. This fishing rod in which the main rod and the first middle rod are also formed as a solid rod is a fishing rod that can withstand large deflections and is sticky, and can prevent body shake during a swing operation. Therefore, the bag is excellent in operability.

  Unlike the above, even if the tip and the former are solid and the two are hollow hollow pipes, as described above, the outer diameter increases, so there is no fiber in the inclined direction and the shaft The torsional rigidity is improved by the presence of the long-direction fibers, and the torsional rigidity is more effectively improved if the inclined direction fibers are further present. Torso is likely to occur in the middle region of the fishing rod. Thus, if the intermediate rods 12 and 14 are formed as hollow rods, the barrel deflection can be prevented more than the case of a solid rod (having a small diameter) having the same bending rigidity. In this case, since the marshal rod is a solid rod, even if the marshal rod is greatly deflected by a large load, the marshal rod can be endured and increased in strength, and becomes a sticky fishing rod. Since the head is also a solid bowl, it is sticky even when bent greatly and is not easily damaged. If the outer diameter of the hollow soot tube is D and the wall thickness is t, the thickness of t / D is preferably 0.04 to 0.4.

  When each ridge in FIG. 1 is a solid casket, an enlarged vertical cross section near the joining portion of the former heel 10 and the first middle heel 12 is shown in FIG. 3 as a representative joining portion. Each of the ridges 10, 12, 14, and 16 has a tapered shape by grinding each surface of a substantially cylindrical solid body, which is made of a synthetic resin as a matrix and pressed and fired with reinforcing fibers oriented substantially in the axial length direction. The solid core portions 10A, 12A and the like formed in the above. Since the axial length direction reinforcing fiber on the surface of the solid core part is cut by grinding, if it is left as it is, it will be easily damaged by peeling off from the end part of the cut fiber when subjected to bending. Therefore, the outer layers 10B, 12B, etc., of reinforcing fibers oriented generally in the axial length direction are formed and reinforced by winding fiber reinforced resin prepregs on the surface.

  The joint portion 10T is provided on the main shaft 10 by forming a stepped portion within the thickness range of the outer layer 10B to form a small diameter portion 10S, around which the fiber reinforced resin prepreg of the joint member body 10TH is wound. In order to reinforce the step boundary between the joint member main body and the main fence main body 10H, the prepreg is wound around the front and rear of the boundary, and fired to form the main body 10H. And the joint part main body 10TH and the reinforcement layer 10Th are integrally joined. The inner surface (fitting surface) of the joining portion 10T formed in this manner is a taper taper. That is, the tip inner diameter B is formed larger than the rear inner diameter C. In the present application, the same applies to the joint portions 12T and 14T, and the taper ratio is formed in the order of the joint portions 10T, 12T, and 14T.

  The smaller the taper rate (including the straight), the more the front side joint part is, the larger the fish is caught and the fishing rod is bent greatly, the tip rod 16 and the second middle rod behind it (Homochi rod) 14 (site of 14T) is directed downward, the joint portion 12T of the second middle collar 14 and the first middle collar 12 is slightly downward, and the first middle collar 12 and the former collar 10 are joined. The joint portion 10T is inclined upward, and the front side is easily extracted. Therefore, it must be configured so that the tip side is not easily removed. On the contrary, the closer to the rear, the stronger the force required for joining, and the easier it is to stick firmly when joining, thus facilitating the joining work and preventing the problem of being firmly attached and unable to be removed. Therefore, the taper ratio is increased toward the rear side.

  In the above example, the taper rate is gradually increased from the front side toward the rear side, but it may have the same taper rate (or the same degree of taper rate) in the middle. For example, the joint portions 14T and 12T have the same small taper rate, and the joint portion 10T has a large taper rate. The outer diameters of the rear joint portions 16t, 14t, and 12t of the flanges 16, 14, and 12 are formed so as to substantially match the inner surface fitting surfaces of the respective cylindrical joint portions 14T, 12T, and 10T.

  The fitting surface length L1 of the joining part of the front and rear rods is longer in the rear part than in the front part of the fishing rod, but the ratio L1 / based on the inner diameter B of the joining part as a representative value. If B is defined, it is preferable to form this ratio so as to increase toward the front part, since it is difficult to disconnect the front part even if a large fish is caught and bent greatly. Furthermore, the joining is not limited to a simple one-step joining fitting surface. For example, the rear joining portion 12t of the first center collar 12 is inserted into the joining section 10T of the main fence. It is often a two-stage seam that enters the position without resistance and is inserted while receiving resistance. If the length of the second stage to be inserted while receiving this resistance is made longer toward the tip side than the original side of the fishing rod, it is possible to sufficiently hold the tip rod that is more likely to fall off.

  In the above explanation, it was a parallel joining, but it may be a reverse joining, or a mixture thereof. The taper ratio in the case of reverse side-by-side joining is that the inner diameter of the tubular joint is large on the rear side (corresponding to C) and small on the front side (corresponding to B). Divide by to find.

  If the front and rear seams (for example, 10 and 12) are solid seams, the front seams and the rear seams can be smoothly joined or joined or removed. In order to make it possible, it is necessary to consider the air venting at the joining site, the size of the residual space, and the like. Therefore, a through hole KA communicating with the outside is provided in the radial direction in a portion (L2 region) outside the fitting surface length L1 region in the joint portion 10T. Alternatively, the inner surface 10TN of the tubular joint portion 10T has an arbitrarily shaped groove such as a groove or a spiral groove extending substantially along the longitudinal direction until the outside is placed in the range of the residual space L2 when joined. Is provided. Or these are used together. A groove may be formed on the surface of the rear joint portion 12t of the front side collar 12 instead of or in combination with the inner surface of the tubular joint portion. Furthermore, air may be released by roughening at least one of the fitting surfaces. Since the joint force is larger toward the former side, the air vent groove or the like is preferably formed with a larger rear joint part than the front joint part.

  Next, when there is no air vent hole or groove, there is a method in which the residual space L2 is lengthened so as to receive the compressive force when joining. In order to widen the residual space L2, a hole KH may be provided in the main fence main body 10H so that the residual space is in the range of L3, and the size can be enlarged. Preferably, when expressed in terms of length, L1 ≦ L2 (L3 when there is a hole KH), the attachment / detachment operation is easy and sticking can be prevented. Since the adhesive force is larger toward the former side, the length L2 (or L3) is preferably longer at the rear side joining site than at the front side joining site.

In addition, a soft layer such as a soft synthetic resin is formed on the inner surface 10TN of the tubular joint portion 10T, the outer periphery of the joint portion 10t, or both of them, thereby preventing sticking. Preferably, the thickness of the soft layer is increased or the softer material is used in the joining portion on the rear side than the joining portion on the fishing rod tip side.
The front and rear heel diameters A and D near the joint part between the solid rivets are set so that the difference in bending rigidity between the two parts is 20% or less regardless of which side is highly rigid. This improves the bending balance. Furthermore, if the difference in rigidity is made smaller at the joining portion on the rear side than the joining portion on the front side of the fishing rod, the bending balance is improved.
The explanation items after the taper rate may be arbitrarily combined with each other.

  With only the core portion oriented generally in the axial length direction, it is easy to tear along the axial length direction when greatly deflected. However, if the outer side has a layer in which the reinforcing fibers are generally oriented in the circumferential direction, the presence of the circumferential reinforcing fibers prevents the tearing and provides a fishing rod that can withstand large deflection. FIG. 4 shows a longitudinal cross-sectional view of an arbitrary ridge 20, an intermediate layer 20B in which the reinforcing fibers are generally oriented in the axial direction, on the outside of the solid core portion 20A in which the reinforcing fibers are oriented in the axial direction, and The outer layer 20 </ b> C is provided on the outer side, and the reinforcing fibers are oriented substantially in the circumferential direction. As a molding method, the solid core portion 20A is formed by grinding a solid rod formed so as to be oriented generally in the axial length direction into a tapered shape, and a fiber reinforced resin prepreg is oriented so as to be oriented generally in the axial length direction from above. In general, it is formed by winding a fiber reinforced resin prepreg so as to be oriented generally in the circumferential direction, followed by pressure firing.

  For example, in the fishing rod of FIG. 1, the main rod 10, the first middle rod 12, the second middle rod 14, and the tip rod 16 have the structure of this rod 20. The intermediate layer may be omitted, but if it is present, the cut fiber portion on the surface of the solid core portion can be reinforced, and peeling can be prevented from being damaged. The presence of reinforcing fibers oriented in the circumferential direction and the inclined direction in the intermediate layer and the presence of reinforcing fibers oriented in the axial length direction and the like are allowed in the outer layer. The tip end may not have the outer layer 20C.

  The thickness of the outer layer 20C may be generally thin, and is 0.1 mm or less, preferably 0.05 mm or less, more preferably 0.03 mm or less when the reinforcing fibers are only circumferential fibers. When the prepreg of the axial length direction fiber is overlapped with the circumferential direction fiber prepreg, the thickness is not more than twice that of the case of only the circumferential direction fiber, that is, 0.2 mm or less, preferably 0.03 to 0.15 mm. If the reinforcing fiber having higher strength than the reinforcing fiber in the solid core portion or the intermediate layer is used for the circumferential reinforcing fiber, the thickness can be further reduced.

The outer layer of the rod 20 has a substantially constant thickness within the rod, but the tip rod is the thinnest between the rods in the entire joint fishing rod, and the thicker the closer the rod is, the thicker the same. It is preferable to form such that there may be a thickness). This is because, as the diameter of the ridge increases, a larger load acts on the outside even with the same amount of deflection, and peeling or cutting from the surface is likely to occur, and this is prevented.
The above outer layer may be provided with fibers in the direction of inclination instead of or in the circumferential direction.

  It is preferable that the intermediate layer is thicker on the side closer to the original side than the front portion in the heel 20. For example, this can be achieved by increasing the number of windings of the prepreg. It is preferable to form so that the head rod is thinnest and thicker as it is closer to the main rod (there may be the same thickness) between each rod in the entire joint fishing rod. The reason is the same as that of the outer layer. In addition, if the tip end is made of high-strength reinforcing fiber and the base end is made highly elastic, the fishing rod strength is improved.

  Increasing the amount of low-strength reinforcing fibers closer to the tip and increasing the amount of high-strength reinforcing fibers closer to the head can increase the strength of the fishing rod and make it thinner and lighter. Also, if you increase the amount of high-strength reinforcing fibers closer to the tip and increase the amount of reinforcing fibers close to the former head, the tone when shaken tends to be torso, As for the return, the tip part returns quickly like the tone.

In order to reduce the weight, we want to make the heel closer to the tip lighter. In this case, the solid core, which is the central layer of the heel, contributes to rigidity and strength compared to the outer middle layer and outer layer. However, it is easy to devise only for weight reduction. Therefore, it is easy to select a material having a small specific gravity for the solid core portion. Therefore, the solid core portion of the heel closer to the tip is made of a material having a smaller specific gravity than the heel closer to the former heel.
Furthermore, although it is common to the wrinkles at any position, if the reinforcing fiber density is higher in the outer area than in the center, the wrinkle has a higher contribution to rigidity and strength, and the outer side has more reinforcing fibers. In the case of using the same amount of reinforcing fiber, it is possible to provide a fishing rod with higher strength and rigidity. To obtain the same strength and rigidity, a smaller amount of reinforcing fiber is required, resulting in lighter weight and lower cost. I can plan.

  The present invention can be used for a joint type fishing rod using a solid rod.
