DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel having a reel body, a cover, a rotor, a handle, a lever,
The present invention relates to components of a fishing reel such as a frame and a side plate of a dual-bearing type reel.

[0002]

2. Description of the Related Art Fishing reels are tools used in fields such as the sea, lakes and rivers. During actual fishing, water or foreign matter such as seawater adheres to the reel body or each operating member, or between the members. It is used under severe environmental conditions, such as intrusion into the interior through gaps. Therefore, fishing reels are generally required to have sufficient corrosion resistance as compared with products in other fields.

Under such demands, for example, Japanese Patent No. 2725175 and Japanese Patent Application Laid-Open No. 2000-41543 disclose a technique for preventing the attachment of moisture and foreign matter by performing a water-repellent treatment on the surface of a fishing tackle. It has been disclosed. That is, in Japanese Patent No. 2725175, by applying a water-repellent treatment only to the outer surface of members of a fishing gear such as a fishing rod, a thread wet with water, dust adsorbed by water droplets, and the like are formed on the outer surface of these members. In addition to preventing adhesion, rust and corrosion on the outer surface of the member are prevented. Also, JP-A-2000-41
No. 543 discloses that particles of a fluorine compound, a silicon compound, or a mixture thereof are volatilized together with a binder in a path through which water enters the inside of the reel body and in a portion of the constituent members inside the reel body where the entered water adheres. They are dispersed in a solvent and applied.

[0004]

By the way, in each of these two prior arts, a water-repellent agent is applied to the surface of a component of a reel to form a water-repellent coating layer.
The application of such a water-repellent agent has a large dimensional variation like ordinary coating (and a dimensional change occurs due to the water-repellent treatment), and it is difficult to control the film thickness. For this reason, it is difficult to apply the method to a place where dimensional accuracy is required, a complicated shape, a narrow portion, a hole, and the like. In other words, in such a coating process, it is difficult to form a uniform film on the threaded portion, small hole, deep hole, acute angle portion, or surface having a complicated shape of the component member, so that corrosion or heterogeneity is caused. There is a problem that metal contact corrosion is easily caused.

Dissimilar metal contact corrosion is a phenomenon in which a noble metal is corroded when a noble metal and a noble metal are electrically connected via an electrolyte such as salt water, and the surface of the noble metal is easily wetted. In this case, electrolytes such as salt water easily stay here, and in a configuration in which a base metal component and a noble metal component are mixed like a reel, contact corrosion of dissimilar metals tends to occur. I will. Therefore, further improvement in terms of water repellency is desired for the constituent members of the reel which are used in a fishing place where the use environment is severe and tend to be reduced in size including details.

[0006] The water-repellent coating layer is soft and vulnerable to scratches. Therefore, the water-repellent coating layer may be touched by hands or other parts during casting operation and winding operation during actual fishing, or movement and transport of a fishing spot. If it hits an obstacle or drops it, the film is peeled off and the water repellent effect cannot be exhibited.

The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent the water-repellent performance from being reduced by an impact or the like regardless of the shape or type of a constituent member, and to be used in an environment of use. It is an object of the present invention to provide a component of a fishing reel excellent in corrosion resistance and durability capable of maintaining a stable water repellent effect even in a severe fishing spot.

[0008]

In order to solve the above-mentioned problems, a fishing reel according to the present invention comprises a metal member main body constituting a fishing reel, and an electrolytic solution formed on a surface of the member main body. Or a chemical etching treatment followed by an anodizing treatment or a chemical conversion treatment to provide a high-order pit film layer formed on the member main body, and a water-repellent agent penetrates into the high-order pit film layer. It is characterized by being held.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fishing reel according to an embodiment of the present invention.

FIG. 1 shows a spinning reel as a fishing reel. As shown in the drawing, a handle 2 that is foldable with respect to the reel body 1 is mounted on the spinning reel. When the handle 2 is rotated, the rotational motion is transmitted to a pinion 6 via a drive gear 4. Then, the pinion 6 is rotated. At the same time, the rotational movement of the handle 2 is transmitted to the spool shaft 8 via an oscillating mechanism (not shown) to move the spool shaft 8 back and forth. At this time, while the rotor 10 rotates integrally with the pinion 6 and the spool 12 moves back and forth together with the spool shaft 8, the fishing line is supplied to a line roller (not shown) 14.
Through the spool 12.

A cover 16 is detachably attached to the reel body 1. A handle 2 includes a handle knob 18, a handle arm 20, and a handle stopper 2.
2. It is provided with a handle stand 24 and the like.

As shown in FIG. 2, all or a part of these constituent members is a member main body 26 formed of a metal material, and is formed by a die casting method (for example, a cold chamber method, a hot chamber method), or a half method. It can be molded by melting and semi-solid processing (for example, thixomolding, rheocasting, SSF, etc.). In this case, as the metal material, for example, a magnesium alloy, an aluminum alloy, a zinc alloy, an iron alloy, or the like can be used.

In the present embodiment, the following technical concept is applied to the surface of the member main body 26.

That is, as shown in FIG. 2, a high-order pit coating layer 28 is formed on the member main body 26, and the water repellent 27 is permeated and held in the coating layer 28. As described above, in order to form the high-order pit coating layer 28 on the member main body 26, as shown in FIG. 3, a material (for example, a base metal such as a magnesium alloy or an aluminum alloy) forming the member main body 26 is used. ) Is prepared (step S1), the material is subjected to electrolytic etching or chemical etching (step S2), and then anodizing treatment or chemical conversion treatment is performed (step S3). Thereby, the member main body 2
6, a high hardness high-order pit coating layer 2 having an insulating property
8 are formed.

As is known, electrolytic etching is performed by using sulfuric acid,
This can be achieved by performing the electrolytic treatment in an acidic aqueous solution such as nitric acid or phosphoric acid. Specifically, an alternating current electrolysis treatment is performed in a phosphoric acid aqueous solution. By this electrolytic etching, the surface of the member main body 26 is etched to form primary pits P1 (see FIG. 2) having irregularities. The pit diameter of the primary pit P1 varies depending on the processing conditions of electrolytic etching, but is generally about 0.1 μm to 10 μm.
Also, the anodizing treatment can be achieved in the same manner as in the related art using an electrolytic solution such as sulfuric acid, oxalic acid, chromic acid, and other organic acids. Specifically, for example, potassium hydroxide, potassium fluoride, sodium phosphate, aluminum hydroxide, in a treatment solution adjusted with potassium permanganate, etc.
The member main body 26 with the contacts is put in, and HAE anodic oxidation treatment is performed under the condition that electricity is supplied for a certain period of time. As a result of this anodizing process, each primary pit P1 having a predetermined depth formed on the surface of the member main body 26 further includes a secondary pit P2 having a predetermined depth.
Is formed. The pit diameter of the secondary pits P2 formed by the anodizing treatment is smaller than the pit diameter of the primary pits P1 formed by the electrolytic etching, and varies depending on the conditions of the anodizing treatment.
It becomes about μm to 0.1 μm.

That is, in the present embodiment, by performing the two-stage processing operation (etching and anodic oxidation (or chemical conversion)) in this manner, the large pits P1 are sequentially changed from large pits P1 to small pits P2. Higher order pit structure in which a plurality of small pits are formed inside each pit (pit diameter: 0.1 μm to 10 μm)
Are effectively formed on the member main body 26.

In the anodic oxidation treatment, a dense anodic oxide film (higher order pit coating layer 28) can be formed by using the above-described HAE anodic oxidation treatment or Dow 17 anodic oxidation treatment. According to these anodizing treatments,
Since an anodic oxide film having a dense and hard composite oxide structure and a spinel structure is formed, a fishing reel excellent in corrosion resistance can be realized. In this case, the thickness of the anodic oxide film (higher order pit film layer 28), that is, the pit P
The depth of 1, P2 is preferably set to 5 to 20 μm in order to maintain stable performance (hard and dense).
This is because when the thickness (depth of the pits P1 and P2) is less than 5 μm, the hardness of the coating becomes insufficient, and when the thickness (depth of the pits P1 and P2) exceeds 20 μm, the coating becomes insufficient. This is because cracks may be generated in the growth process of.

In order to allow the water-repellent agent 27 to penetrate into the high-order pit film layer 28 formed as described above, as shown in FIG. 26 is immersed in a water repellent solution for a predetermined time (for example, one hour), or the water repellent is continuously sprayed (for example, in a paint state) on the high-order pit coating layer 28 (Step S).
4) Then, drying may be performed, for example, at 80 ° C. to 100 ° C. for 60 minutes (step S5). The water repellent 27 is preferably a compound having oil repellency. Examples of such a compound include, for example, a fluorine compound and a silicon compound, particularly a fluoroalkyl group such as polytetrafluoroethylene or fluoroalkylsilane. And the like. Of course, a water repellent agent 27 having no oil repellency (for example, a fluorine compound or a silicon compound) can also be used.

As described above, the higher-order pits P1 and P2 formed by etching, anodic oxidation or the like lower the surface free energy and make the surface of the member main body 26 hard to wet with water. When a water-repellent agent having 6 or more water-repellent groups (fluoroalkyl groups) in the main chain penetrates into these pits P1 and P2, the contact angle with water becomes 150 ° or more, and oil and oil Is 100 ° or more.

In the pinning reel shown in FIG. 1, the handle arm 20, the handle stopper 22,
The handle stand 24 has a main body member formed of an Mg alloy, and a high-order pit coating layer 28 formed by retaining a water repellent agent 27 therein. In this case, Mg
It is preferable that a metal member that comes into contact with or comes close to (for example, within 1 mm) a member made of an alloy has an electrode potential difference from the Mg alloy of 1 V or less. Such materials include A
1 alloy (electrode potential -0.7 to -0.9 V), Zn alloy (electrode potential -0.7 to -1.0 V), or the like can be used. Therefore, in the present embodiment, the handle arm 20, the handle stopper 22, the handle stand 2
4, the cap 32, the handle stand rivet 34, and the handle noble rivet 36 are made of Al.
Preferably, it is formed of an alloy.

Further, in addition to the above, washers 38, 40
As described above, when the alloy part of the component (the handle arm 20) comes into contact with the alloy part of the component member, a material having an electrode potential difference of 1 V or less may be applied to the contact part. Further, the handle shaft 42 is also preferably formed in consideration of the electrode potential difference with the constituent members, but is generally formed of stainless steel due to strength problems. The electrode potential difference between stainless steel and Mg alloy exceeds 1 V.

In particular, a base metal such as an Mg alloy or an Al alloy (a metal that undergoes corrosion) and a noble metal having a much higher electrode potential (a metal that causes corrosion) are in contact with or close to each other. In the case where the base metal and the noble metal are combined, for example, if the high-order pit coating layer 28 in which the water repellent 27 is permeated and held is formed only on the surface of the base metal, Even if the higher-order pit coating layer 28 is not provided on the side, the conventional corrosion resistance can be secured. Here, the noble metal refers to gold, silver, copper, copper alloy, titanium, titanium alloy, iron, iron alloy, nickel, nickel alloy and the like.

The above-described means for preventing contact corrosion between a base metal and a noble metal is employed in the present embodiment.
That is, in the present embodiment, the drive gear 4 is formed of, for example, a copper alloy or a stainless steel alloy, and the slider of the oscillating mechanism (not shown) is formed of, for example, a Ni-plated zinc alloy. Alternatively, the reel body 1 such as a reel body and a side plate that comes into contact with the slider is made of, for example, an Mg alloy or an Al alloy. Then, on the surface of the reel body 1 formed of a base metal, a high-order pit coating layer 28 in which a water repellent 27 is permeated and held is formed.
Thereby, dissimilar metal contact (proximity) corrosion is prevented. In this case, the thickness (depth of pits P1 and P2) of the anodic oxide film 28 at the portion where the dissimilar metal parts are in contact with or close to each other
Is preferably thicker than other parts. For example, the thickness of the portion where the dissimilar metal parts are in contact is 10 to 20 μm.
m, and the thickness of other portions is set to 5 to 20 μm. In addition, the contact of the anodizing treatment, so that the thickness of the anodized film at the joint of each member does not become thin,
It is preferable to set at a portion where there is no possibility of corrosion.

As described above, in the present embodiment, the surface of the member main body 26 is subjected to electrolytic or chemical etching treatment, followed by anodic oxidation treatment or chemical conversion treatment, whereby the high-order pit film is formed on the member main body 26. The layer 28 is formed, and the water repellent 27 is permeated and retained in the higher-order pit coating layer 28 (in the pits of the higher-order pit coating layer). That is, the water-repellent 27 is not applied to the surface of the member main body 26 to form the water-repellent coating layer. And the anodic oxide film 28 (the water repellent 27 has completely penetrated into the higher order pits P1 and P2).

Therefore, the member main body 2 is subjected to the water repellent treatment.
Since there is no change in the dimensions of No. 6, there is no need to control the film thickness as in the case of ordinary coating with large dimensional variations, and it is easy to apply to places where precision is required and to components with complicated shapes. In addition, a water-repellent treatment can be reliably performed.

The coating layer 28 in which the water repellent is permeated and held.
Because of its high hardness, it is resistant to scratches, even if it is touched, hits other obstacles, or dropped, the water repellency does not decrease, even in a fishing environment where the use environment is severe A stable water repellent effect can be maintained.

In this embodiment, the water repellent 27
If a compound having oil repellency is used, the water repellency can be prevented from lowering due to the adhesion of grease, oil, hand oil and other fats and oils, and the water repellency can be maintained for a longer period of time.

Further, in this embodiment, if the member main body 26 in which the dissimilar metal is in contact with or in proximity to the member is subjected to the water-repellent treatment having the above-mentioned effect, the stagnation of the electrolyte such as salt water is eliminated and the contact with the dissimilar metal is prevented. The occurrence of corrosion can be suppressed.

It is needless to say that the present invention is not limited to the above embodiment, but can be variously modified without departing from the scope of the invention. For example, in the embodiment described above, the present invention is applied to the constituent members of the spinning reel. However, as the constituent members of the fishing reel, the reel body, cover, rotor,
In addition to the handle and the lever, all parts such as a frame and a side plate of a dual-bearing type reel are applicable, and the technical idea of the present invention can be applied to these constituent members.
