Also, it is preferable that the fishing rod pipe is constituted of plural rod pipes R2-R5 and the part where the rigidity is successively made small from the tip side of the fishing rod pipe to the rod butt side is formed at a part of one or more rod pipes R2-R5 for constituting the fishing rod pipe.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fishing rod, and more particularly to a fishing rod.
The purpose is to improve the bending balance as a whole.

[0002]

2. Description of the Related Art The life of a fishing rod is a condition (bending condition).
The rigidity of the tip of the tip side is reduced so that the tip side is easily bent, and the rigidity of the base side is increased so that the base side is hardly bent. Thus, it is possible to cope with an arbitrary load according to the type of the rod, from a small load to a large load.

[0003]

However, in a general fishing rod, a part of the rod tip becomes larger,
In this case, the distance from the gripped rod bottom (original) to the rod tip on which tension acts is increased. A fishing rod with a condition that the base side of the fishing rod, which is called the body condition and the main condition, is relatively easy to bend has been devised, but even in such a case, it is not enough. If you do so, you will have a problem that your fatigue will be severe. Further, in a spatula rod or the like, it is required that the size is increased when a fish is hung, but there has been no rod that sufficiently satisfies this requirement.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a fishing rod in which a bending rod as a whole has a good bending balance and is less fatigued even when operated for a long time. . Further, the present invention provides a fishing rod which becomes large when fish is caught thereon and is suitable for spatula fishing.

[0005]

According to the present invention, in order to achieve the above object, in a fishing rod wound with a prepreg made of fiber reinforced synthetic resin, the rigidity of a rod pipe main body increases gradually from a tip side to a rod end side. And a portion where the rigidity decreases from the tip end side toward the rod end side.

[0006]

Embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a fishing rod R according to an embodiment of the present invention will be described using an example of five consecutive fishing rods. FIG.
, R1 is a tip, R2 is a 2nd rod, R3 is a 3rd rod, R4 is a 4th rod, and R5 is a former rod. The fishing rod R in the present embodiment is configured by winding a prepreg made of the same fiber-reinforced synthetic resin as that conventionally known. In FIG. 1, reference numeral r indicates a conventional fishing rod as a comparative example.

In the present embodiment, the fishing rod R is configured such that its rigidity is generally increased from the tip side to the rod bottom side like a normal fishing rod. And the original rod pipe R5 are formed so that the rigidity decreases in order from the end on the tip side to the end on the rod bottom side. Here, the term “sequentially” includes a case where the ratio gradually changes at a constant ratio and a case where the ratio changes gradually. The rigidity balance of the rod tube body excludes grips, reel seats, guides, and other parts, as well as reinforcement layers for the overlaying and joining parts for mounting the parts and overlaying layers for adjusting the fitting dimensions. Shall be considered.

The rigidity of these rod pipes R4, R5 is such that the end of the rod butt side is less than 100, with the end on the tip side being 100. That is, the difference in rigidity is set in a range of 70 to 99% at the rod end side end with respect to the tip end side end. In practice, depending on the overall rod tone setting, if it is set to less than about 75%, there is a possibility that the rod pipe will break due to a decrease in strength (when no measures are taken). Further, when the content is 95 to 99%, the difference in rigidity is small,
The desired bending cannot be sufficiently obtained. Therefore, it is preferable to set it in the range of preferably 80 to 95%.

In the above description, the rigidity of the fourth rod pipe R4 and the original rod pipe R5 is gradually reduced from the rod tip side to the rod bottom side. However, the present invention is not limited to this. In addition, the range in which the rigidity is gradually reduced toward the bottom of the rod with one rod pipe may be the entire length or a part thereof, but is 20% or more of the entire length of the rod pipe or 20 cm or more. Is preferred. Alternatively, only one of the middle rods R2 to R4 may be sequentially reduced in rigidity from the rod tip side to the rod bottom side.

As described above, by providing a range of low rigidity at a specific position of the rod tube, this portion is easily bent, and can be bent in an arc shape with a small force. Easier to remove. Further, by doing so, it is possible to obtain a bending balance suitable for the transfer operation of the device.

As shown in FIG. 2, in order to reduce the rigidity sequentially from the rod tip side to the rod bottom side, as shown in FIG.
The tapered shape is such that the diameter becomes smaller as going from the rod tip side (the left side in the figure) to the rod bottom side (the right side in the figure). The inclination of this taper is 3/1
000 or less. This taper change may be the same taper rate over the entire length of the rod, especially 0.5 / 100
In the case of 0 or less, even if it is a uniform taper, the influence of the strength decrease is small. Also, the taper at the tip of the rod pipe is 1/100
When it is 0 or more, it is preferable to make the taper of the rear part from the middle part of the rod pipe smaller than the tip and make it closer to straight. By doing so, the strength and condition of the rod tube can be balanced. Further, the rod end side may be formed in a straight shape. The thickness of the main body layer of the rod tube is formed substantially the same over the entire length. In FIG.
Is a reinforcing layer at the joint.

The rigidity can be adjusted by changing the diameter of the rod tube by changing the shape of the core used in the production of the rod tube to a desired taper angle, or by changing the elastic modulus of the portion. It is performed by changing the thickness or the thickness (the number of prepreg windings). By adjusting the rigidity in this manner, the fibers of the prepreg are not cut, and the strength is not reduced. In the above case, the rigidity is adjusted in the selection of the material and the prepreg winding step, but in the present invention, it is also possible to adjust the rigidity by machining (polishing, grinding, etc.) after molding. is there. Furthermore, you may perform by combining these.

In the above description, the description has been made on the premise that five rod pipes are joined. However, the present invention is not limited to this, and it goes without saying that the present invention can be applied to a case where another number of rod pipes are joined. No.

[0015]

As described above, according to the fishing rod of the present invention,
The bending of a predetermined portion (desired portion) of the fishing rod can be significantly increased, and a fishing rod with excellent bending balance and good operability can be provided. Further, according to the present invention, when the tip of the tip is the same height as shown in FIG. 1, the distance between the tip of the rod and the tip can be made shorter than that of the conventional example, and the hand gripped during the operation of the fishing rod is used. Can be reduced, so that fatigue during operation can be reduced. Furthermore, according to the present invention, since the change in rigidity is adjusted by the configuration of the rod tube main body, an adjusting component (adjusting member) is not required, and the weight can be reduced.
