DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod and, more particularly, to a method for reinforcing a head rod in a swing type external through rod.

[0002]

2. Description of the Related Art In an out-guide fishing rod in which a guide body is provided outside the rod of each rod piece, the diameter of the tip rod is set to be as small as possible. The tip rod is a part that receives particularly large bending during fishing and is subjected to strong stress. Therefore, the tip rod having such a small diameter needs to have sufficient strength.

In general, when a fishing rod is manufactured, it is possible to sufficiently reduce the weight by forming the whole rod using a hollow rod tube, but a smaller diameter can be expected to have a lighter weight effect. Forming the tip rod into a small diameter is naturally limited due to restrictions on the method of manufacturing the hollow tube. Moreover, it cannot be said that it is sufficient from the viewpoint of strength. Therefore, as a method of forming the tip rod, a solid rod pipe is used on the tip side, that is, the tip part, and a hollow rod pipe is used on the base side of the tip rod, and a method of joining (joining) the two is adopted. There are many.

[0004] In this case, a solid rod tube which can be formed to be small in diameter is used for the tip portion of the tip rod, and it is press-fitted and fixed to a hollow rod tube which is a front portion of the tip rod. However, as described above, since the tip portion of the tip rod has a small diameter, when the tip portion is largely bent, stress tends to concentrate on the region of the tip portion. In particular, since the joint portion between the solid rod tube and the hollow rod tube is discontinuous, stress tends to concentrate, causing breakage, cracks, and the like.

In order to reinforce the strength of the joint portion between the solid rod tube and the hollow rod tube, there is a problem in which the outer periphery of the rod in the joint region is covered with a prepreg, a resin, etc.
There is a structure in which a reinforcing member is interposed between a solid rod tube and a hollow rod tube at a joint portion. However, in the former case, when stress is concentrated, the outer shape of the reinforced prepreg layer, the resin layer, and the like becomes thicker, and cracks are likely to occur.

On the other hand, in the latter case, since the reinforcing member is quantitatively heavy, the balance of the center of gravity of the spike approaches the position of the joint. In other words, the rod is curved because the joint portion is close to the top of the bending, so that the hollow rod tube is mechanically unreasonable. Thus, none of the structures can be said to be a complete reinforcement of the joint.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. That is, an object of the present invention is to provide a swing-out fishing rod in which a joint portion of a head rod composed of a solid pipe and a hollow pipe is reinforced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a swing-out fishing rod according to the present invention will be described below with reference to the drawings. Note that the swing rod used here is an external rod in which a guide body is provided outside the rod of each rod piece. FIG. 1 is an overall view of a swing-out fishing rod, and FIG. 2 is an enlarged view of the tip rod A thereof. FIG. 3 schematically shows a joint portion between the solid pipe 1 and the hollow pipe 2, that is, the structure of the mounting joint 3. As shown in FIG.

As shown in FIGS. 1 and 2, a plurality of floating guides 4 are slidably provided on the tip rod A up to a top guide provided at the tip of the rod. It is known that the provision of the plurality of floating guides 4 disperses the bending force applied to the tip rod A.
The floating guide 4 is a line guide composed of a guide ring that directly guides (guides) the fishing line and a support that supports the guide ring.

Further, the support of the floating guide 4 is provided with a foot 41 which is inserted and slid and fixed to the rod tube so that the floating guide can be moved out of the rod A when the fishing rod is swung out. Is fixedly arranged at an appropriate position.

As shown in FIG. 2, the tip rod A is composed of a solid pipe 1 at the tip of the rod and a hollow pipe 2 at the end of the rod, and the solid pipe 1 is mounted and joined to the hollow pipe 2. . Each of the solid pipe 1 and the hollow pipe 2 is formed in a tapered shape such that the diameter gradually decreases toward the tip end, and a tapered tip rod A is formed as a whole.

The solid pipe 1 in which the solid pipe 1 is mounted on the hollow pipe 2
Is formed as a reduced diameter portion 11 whose diameter is reduced. The outer diameter of the reduced diameter portion 11 is substantially the same as the inner diameter of the hollow tube 2. , Or slightly larger.

3A, the method of joining the solid pipe 1 and the hollow pipe 2 is as follows. The solid pipe 1 having the reduced diameter portion 11 is already manufactured, and the reduced diameter portion 11 is connected to the hollow pipe. 2 is attached and joined (this attached and joined portion is designated as an attachment joint 3 as indicated by reference numeral 3). In the joined state, as described above, when the outer diameter of the reduced diameter portion 11 of the solid pipe 1 is slightly smaller than the inner diameter of the hollow pipe 2 (skim fit state), When the inner diameter of the tube 2 is the same (Taribame state)
In some cases, the outer diameter of the reduced diameter portion 11 of the solid pipe is larger than the inner diameter of the hollow pipe 2 (shrink fit). Preferably, an adhesive is applied to the reduced-diameter portion 11 of the solid pipe and both pipes (1,
If 2) is joined, the joining state will be more reliable.

At the joint between the solid pipe 1 and the hollow pipe 2, one of a plurality of slide guides 4 slidably provided is designed to be arranged and fixed. Is one of the major features of the present invention. More specifically, at least a part of the mounting joint 3 including the seam T can be arranged and fixed so as to surround the foot 41 of the floating guide. In this case, when the arrangement is fixed, the foot 41 of the floating guide is externally inserted into the spikestick and is in a state of being tightened and stopped. Therefore, by the foot 41 of the floating guide,
The strength of the mounting joint 3 including the seam T is reinforced.

Further, when the tip rod A is bent, the joint T is surrounded by the foot 41 of the floating guide, so that stress is concentrated only on the joint T even if a force is applied to the mounting joint area. Not safe. That is, the force applied to the mounting joint 3 is dispersed and alleviated, and breakage, cracks, and the like are prevented from occurring at the joints as in the conventional case described above.

The solid pipe 1 is thinner than the hollow pipe 2 but is solid, so that it becomes larger in weight. Therefore, from the viewpoint of the balance between the length of the solid pipe 1 and the length of the hollow pipe 2, it is preferable that the solid pipe 1 exceeds 1/2 of the entire length of the tip rod,
In other words, the solid pipe 1 may be set longer than the hollow pipe 2.

By setting the solid pipe 1 longer than the hollow pipe 2 in this manner, the balance of the center of gravity of the tip rod A is at least within the first half of the tip rod A, and the seam which is a discontinuous part is located. In the tip rod A having T, the stress concentration point is deviated before the mounting joint 3. With such a positional relationship being set, the mounting joint can be further reinforced and secured by further allowing the foot 41 of the floating guide to be arranged and fixed at the joint. As a preferred embodiment of this case, for example, assuming that the tip rod A has a length of 930 mm, the length of the solid pipe 1 is 530 mm, the length of the hollow pipe 2 is 400 mm, Becomes 40 mm in length.

From the viewpoint of the elastic modulus of the solid pipe 1 and the hollow pipe 2, it is preferable to use a hollow pipe having a higher elasticity than the solid pipe 1. By doing so, when the tip rod A flexes,
Since an apex of bending occurs in the region of the lower elasticity solid pipe 1, in the tip rod A having the seam T which is a discontinuous portion, a portion where stress is concentrated can be removed from the mounting joint 3. As a preferred embodiment of this case, for example, the elastic modulus of the hollow tube 2 is set to 30,000 to 44,000 Kgf / m.
m ² , the elastic modulus of the solid pipe 1 is 20,000 to 3
It becomes 5,000 Kgf / mm ² . By setting such a relationship of the elastic modulus and further enabling the foot 41 of the floating guide to be arranged and fixed at the joint, the mounting joint is further reinforced and safe.

From the viewpoint of the outer shape of the rod pipe, it is preferable that the outer taper of the solid pipe 1 be higher than the outer taper of the hollow pipe 2. That is, since the solid pipe 1 is formed to have a small diameter with a higher external taper than the hollow pipe 2, when the tip rod A bends, a vertex of the bending naturally occurs in the region of the solid pipe 1. As a result, the portion where the stress concentrates is the joint 3 of the two pipes.
More off. By setting such an external relationship, and further allowing the foot 41 of the floating guide to be arranged and fixed at the joint, the mounting joint is further reinforced and safe.

The solid pipe 1 and the hollow pipe 2 as described above
In the length relationship, elastic modulus relationship, and outer shape relationship with
It is more preferable that all conditions are included in forming the head rod A, but even if any one of the conditions is included, the effect is sufficiently exhibited.

That is, if at least one of these conditions is included, the spike rod A in which stress is not concentrated on the joint T between the solid pipe 1 and the hollow pipe 2 which is a major feature of the present invention. . In addition, since the foot 41 of the floating guide is arranged and fixed, the strength of the mounting joint area increases.
Accordingly, the tip rod A can sufficiently withstand a large bending, and further, there is no occurrence of breakage or cracking at the joint T.

FIG. 4 shows an example of another structure having a different mounting joint. Specifically, both pipes (1, 1) are covered so as to cover certain regions on both sides from the joint T between the solid pipe 1 and the hollow pipe 2.
The reinforcing layer 5 is formed so as to cover the region of the mounting joint 3 including the joint T of 2). As the material of the reinforcing layer 5, for example, a reinforcing fiber prepreg or a reinforcing fiber tape is adopted, and the reinforcing layer 5 is preferably formed by winding the reinforcing fiber prepreg thinly.

Here, the foot 41 of one floating guide is attached to the portion of the reinforcing layer 5 covering the mounting joint 3 including the joint T.
Are set so that they can be fixedly arranged. Therefore, the joint T and the attachment joint 3 can have higher strength by both the reinforcing fiber prepreg, which is the reinforcing layer 5, and the foot 41 of the floating guide.

When the tip rod A is bent, the mounting joint 3
Even if a force is applied to the area, since the floating guide 4 is disposed in the mounting joint 3, the force applied to the mounting joint 3 by the floating guide 4 is reduced as described above.

FIG. 5 shows an example of another structure having a different mounting joint. As can be seen from the figure, a reinforcing member 6 is provided on the outer circumference of the reduced diameter portion 11 in order to increase the strength of the mounting joint 3. Also in this case, the foot 41 of one floating guide can be fixedly arranged at least at a part of the attachment joint including the seam T. As a material of the reinforcing member 6, preferably,
If a material having a lower elasticity than the hollow tube material, for example, a rubber material or a soft plastic, is used, the flexibility is not impaired.

In the mounting joint 3 in which the reinforcing member 6 is inserted, the stress is dispersed by the floating guide 4 even when a force is applied to the area of the mounting joint 3 when the tip rod A is bent. In addition, the strength is ensured by the reinforcing member 6. In this case, by applying a rubber material to the reinforcing member 6, there is also an advantage that the cushion function is added to the rod pipe and the rod pipe is reliably stopped. In addition, the strength of the reduced diameter portion 11 of the solid pipe is enhanced, and the strength is further increased by the floating guide 4 that can be fixedly disposed there.

Although the present invention has been described above, the present invention is not limited only to the embodiment, and it goes without saying that various other modifications can be made without departing from the essence of the present invention. For example, regarding the suitable position of the mounting joint of the tip rod as described in FIG. 3 or the elastic modulus and the external taper of the solid pipe and the hollow pipe, those conditions are applied to FIGS. 4 and 5. Of course it is good. The feet of the floating guide
It can be arranged and fixed so as to surround at least a part of the attachment joint 3 including the seam T, but the surrounding part from the seam can be set in any manner depending on the width of the foot. It is.

[0036]

As described above, according to the present invention,
When the tip rod is bent, the floating guide can be fixedly arranged at the mounting joint including the joint between the solid pipe and the hollow pipe, so the stress applied thereto is dispersed, and the joint at both pipes and the mounting joint break. No cracks or the like occur. Also, in the mounting joint area, stress is not intentionally concentrated by specifying the position of the joint between the solid pipe and the hollow pipe, or the elastic modulus and the external taper degree of the solid pipe and the hollow pipe. As a result, it is possible to prevent breakage and cracks of the spike.
