DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having a head rod tube.

[0002]

2. Description of the Related Art Generally, a tip portion of a fishing rod located at the tip of a fishing rod is close to the water surface, so that it is easily wetted by water. When the tip portion of the tip is wet with water, the whole fishing rod is felt heavy, the weight is held, and the timing of operating the fishing rod is delayed, so that the operability of the fishing rod is reduced.
In particular, when the tip portion is in water, the operation becomes more difficult due to the resistance of water, and the feeling of holding increases. Therefore, the operation speed of the fishing rod is reduced.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fishing rod excellent in operability which can prevent a weight from being lifted and can increase an operation speed.

[0004]

A fishing rod according to the present invention which solves the above-mentioned object is formed by winding a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin and having a specific gravity of 1.0 or more. In addition, a water-repellent coating is coated on the outside of the head rod pipe to enable the head rod pipe to float on water or seawater.

Further, according to the present invention, there is provided a tip rod pipe formed by winding a fiber reinforced prepreg in which a reinforcing fiber is impregnated with a synthetic resin, and has a myriad of minute recesses on the surface outside the tip rod pipe. A fishing rod is provided which has a water-repellent coating formed thereon, and which can hold air in a minute concave portion formed on the surface of the water-repellent coating when the portion on which the water-repellent coating is formed is put into water.

1 to 4 show a fishing rod according to a preferred embodiment of the present invention. Fishing rod 1 in the present embodiment
Numeral 0 indicates a state where the tip is floated in the water W by hanging on a rod fixed to the waterside. This fishing rod 10 is formed by joining a plurality of rod pipes 12, a grip portion 14 is provided on the rod pipe on the hand side, and a fishing line binding device 18 is provided on the tip of a tip rod pipe 16 located at the tip. Is installed. The tip rod 16 is not limited to the rod located at the most distal end, and may include the rod located second from the distal end when the water is easily wet near the water surface. in this case,
As for the rod tube located at the second position, a water-repellent film 24 described later may be formed only on a portion which is easily wetted by water,
It is not always necessary to form a water-repellent coating described later over the entire length.

As shown in an enlarged cross-sectional view of the tip rod tube 16 in FIG. 2, the tip rod tube 16 of the present embodiment is a fiber reinforced prepreg in which reinforcing fibers are impregnated with a synthetic resin, similarly to the other rod tubes 12. It has a cylindrical rod pipe main body 20 formed by winding a sheet, and a coating layer 22 for protecting the rod pipe main body is formed on the outer peripheral surface of the rod pipe main body 20. A water-repellent coating 24 made of a water-repellent resin containing fine water-repellent particles is fixed to an outer peripheral portion of the tip rod tube 16. In addition,
The water-repellent coating 24 preferably has a complex uneven surface having innumerable "fine recesses" (not shown) and innumerable "fine recesses" deeper than the recesses. FIG.
Fig. 7 shows a state in which the infinite number of minute concave portions 26 retain air therein, thereby forming an air layer R between the water W and the tip rod tube 16. This air layer R may be formed in a layered form as long as air is held on the surface of the rod tube in water, or may be formed as fine air bubbles in micropores on the surface. Good.

The term "fixing" refers to, for example, coating (liquid or powder), printing, wrapping of a prepreg or a resin film, vapor deposition, plating, bonding, etc.
4 is formed. Also, "water repellency"
The water droplet has a contact angle of at least 130 degrees or more, preferably 140 degrees or more, and more preferably 150 degrees to 180 degrees, which means that it contains super water repellency having a very large water repellency.

Such a water-repellent coating 24 is formed using a water-repellent resin such as a fluororesin or a silicone resin in which water-repellent particles such as fluororesin particles are dispersed and mixed. When winding the prepreg sheet to form the rod tube main body 20, by previously fixing the water-repellent resin mixture to the prepreg sheet together with the coating layer 22 as described above, at the same time as the completion of the rod tube main body 22,
It can be formed on the outer peripheral surface of the rod pipe main body 20. The thickness of the water-repellent coating 28 formed in this manner is 2 μm to 15 μm in order to reduce the weight of the fishing rod 10 and to prevent the fishing rod from being held.
It is preferable that the thickness be about μm. Further, in order to improve the durability, it is preferable that the hardness of the water-repellent coating 24 is formed at a pencil height of 2H or more, preferably about 3H to 6H. When such a water-repellent coating 24 is formed on the entire rod tube main body 20, the coating layer 22 can be omitted.

Innumerable minute concave portions 26 of the highly water-repellent coating 24
Is formed by combining convex portions formed of a group of a plurality of water-repellent particles exposed to the surface by bonding with a binder and fine concave portions formed between these convex portions. . In this case, the concept of “small” refers to such a small size that air entering a minute concave portion is retained in the concave portion and water droplets do not enter the concave portion. As a specific example, when the water-repellent coating 24 is viewed on a plane,
The number of combinations of the concave portion and the convex portion is, for example, 100 or more or 1
000 or more, preferably 5000 to 1,000,000 or more. In other words, the concept of “micro” means that the height difference between the concave portion and the convex portion is 10 μm or less, preferably 0.1 to 5 μm, and the pitch between the concave portion and the convex portion is 10 μm. Less than,
Preferably, it is set to 0.1 to 5 μm.

The fine uneven surface forming the fine concave portion of the water-repellent coating 24 is a concave-convex surface forming a concave portion deeper than the particle size of the fine water-repellent particles. The air that has entered the fine recess is retained in this recess, and the fineness is such that water droplets do not enter the recess,
As a specific example, when viewed on the plane of the water-repellent coating 24, the number of combinations of concave portions and convex portions is, for example, 10 or more or 100 or more in terms of a unit area of 1 square millimeter, Preferably, it means that 1,000 to 500,000 or more are formed. In other words, the concept of “fine” means that the height difference between the concave portion and the convex portion is 10 μm or less, preferably 0.2 to 5 μm, and the pitch between the concave portion and the convex portion is 100 μm. Hereinafter, it is preferably set to 0.2 to 5 μm.

When the water-repellent particles are concentrated on the side of the rod-tube main body 20, the fastening (adhesion) area between the rod-tube main body 20 or the coating film 22 and the water-repellent coating 24 is reduced. As a result, the adhesion (adhesion) of the water-repellent coating 24 to the rod tube main body 20 or the coating film 22 may be reduced, so that the water-repellent particles may be concentrated on the surface side of the water-repellent coating 24 and in the vicinity thereof. preferable.

By concentrating the water-repellent particles on the surface side of the water-repellent film 24 and in the vicinity thereof, the boundary surface between the rod body 20 or the coating film 22 and the water-repellent film 24 has few water-repellent particles. Since it can be made to be in a state where it is almost or not, it is possible to increase a fixing (adhering) area between the rod tube main body 20 or the coating film 22 and the water repellent film 24. As a result, the adhesion (adhesion) of the water-repellent coating 24 to the rod tube main body 22 or the coating film 22 is obtained.
Can be improved.

Further, on the surface of the tip rod tube 16, as shown in FIG. 3, there are formed uneven rows 28 arranged regularly. The concavo-convex row 28 in the present embodiment is a
To make it easier to pull up from the water, like pulling out 6 forward,
The concave portions and the convex portions having a size larger than the minute concave portion 26 are alternately arranged along the longitudinal direction. The recesses and projections forming these uneven rows 28 may have a depth of the recesses, that is, a height of the projections of approximately 0.01 to 0.5 mm or less, a width of approximately 0.5 mm or less, and a length of approximately 0.5 mm or less. It is preferable that the shape is appropriately formed according to the direction, the pitch between the concave portions and the convex portions is formed to be 1.0 mm or less, and the pitch between the adjacent uneven rows 28 is formed to be about 1.0 mm or less.

Instead of forming the concavo-convex array 28 along the longitudinal direction of the tip rod tube 16 as described above, it is also possible to form the concavo-convex array 28 in a circumferential direction or a direction inclined with respect to the axis. 28 may be arranged in a direction crossing each other. When the concavo-convex rows 28 are arranged in the circumferential direction or the inclined direction, or when they are arranged in a direction intersecting with each other, these concavo-convex rows 28 act as a guide in the water to move the tip rod tube 16. Is easy. Further, instead of such an uneven row 28, an uneven surface in which concave portions and convex portions are irregularly arranged over a part of or the entire surface of the tip rod tube 16 may be formed. The uneven surface in this case is, for example, a dimple surface having a large number of concave portions formed thereon, a surface having a large number of projections formed thereon, a surface having a large number of wrinkled ridges or grooves, a corrugated ridge or a groove formed. It can be formed on an appropriate surface such as a surface. In any case, as shown in FIG. 2, minute concave portions 26 or minute concave portions are formed on the surface portions of the concave and convex portions 28 and the concave and convex portions of the concave and convex surfaces, respectively. It is preferred to combine.

The spike rod 16 has such a specific gravity that it can float at a suitable position with respect to water when placed in fresh water or seawater. If the tip rod tube 16 floats too much in the water, for example, the tip rod tube required for a spatula rod cannot be maintained in the water, and the weight cannot be prevented. For this reason, it is preferable that the spike rod tube 16 be formed to have a specific gravity in the range of 1.0 to 1.8 or 0.8 to 2.0. Further, the overall buoyancy of the tip rod 16 including the buoyancy caused by the air layer R is 2% of the weight of the tip rod 16.
It is preferably at most twice.

As shown in FIG. 4, the fishing line binding device 18 provided at the tip of the tip rod tube 16 is fixed to the tip rod tube 16 and is rotatably attached to the fixing portion 30. A fishing line binding portion 32, and a fishing line (not shown) is bound to the fishing line binding portion 32. The fishing line binding device 18 is also preferably provided with water repellency by performing a surface treatment as described in relation to FIG. in this case,
It is most preferable to impart water repellency to the entire surface of the fishing line binding device 18. However, it may be formed only on the outer surface of the fixing portion 30 or only on the outside of the fishing line binding portion 32. It is also possible to form an uneven row or uneven surface as shown in FIG.

By imparting water repellency to the fishing line binding device 18 in this way, the drainage of the tip including the fishing line binding device 30 is improved.

In the fishing rod 10 formed as described above, the specific gravity of the tip rod tube 16 is formed in the range of 1.0 to 1.8 or 0.8 to 2.0, and its buoyancy is reduced by the weight of the tip rod tube 16. By setting the width to twice or less, the spike rod tube 16 can be maintained at a suitable position close to the water surface without floating too much. The water-repellent coating 24 formed on the surface of the tip rod tube 16 prevents water droplets from remaining on the tip rod tube 16 and improves the drainability of the fishing rod 10.

Further, even when the tip of the fishing rod 10 is submerged in water, a thin air layer R is formed on the surface of the tip rod tube 16, so that the buoyancy prevents the weight from being lifted and the drainage in the water. Good resistance, low resistance in water,
Therefore, the operation speed is improved, and the operability of the fishing rod 10 is significantly improved. Thereby, a timing delay at the time of the matching operation with respect to the fish signal can be prevented.

Further, by imparting water repellency (super water repellency) to the fishing line binding device 18 in addition to the tip rod tube 16, the drainage of the entire tip portion is improved and the adhesion of water is prevented. Thus, the lifting is prevented, and the operability of the fishing rod 10 is greatly improved.

Such a tip rod tube 16 is used as the rod tube 1 on the hand side.
Second, for example, in the case of successive fishing rods 10, since the resistance of the tip rod 16 in water is small, it is possible to prevent the tip rod 16 from coming off even if the operation speed is high.

[0023]

As apparent from the above, according to the present invention,
There is provided a fishing rod excellent in operability, capable of preventing a weight and increasing an operation speed.
