Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel component such as a reel body, a cover, a rotor, a handle of a spinning reel, a frame of both bearing reels, and an outer plate.

[0002]

2. Description of the Related Art Generally, aluminum alloys and resin materials are often used for members constituting fishing reels. The aluminum-based material is satisfactory in strength as a constituent member of the reel, but is relatively heavy in terms of weight and unsatisfactory in terms of formability.

Further, the resin material is a material that is satisfactory in terms of weight, corrosion resistance, and cost as a constituent member of the reel, but is unsatisfactory in terms of strength. For example, when a resin material is used for a member that constitutes a fishing reel, it is easily deformed or damaged by hitting a rock or the like in a fishing place, which is a harsh environment. Therefore, there is a possibility that the function as a reel cannot be fully exhibited.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a corrosion resistance and strength which are satisfactory as a member constituting a reel, and a fishing reel which is lightweight and has good moldability. The purpose is to provide a component.

[0005]

[Means for Solving the Problems] The present inventors have focused on the characteristics of magnesium-based materials, such as high strength, ultralight weight, and good moldability, and have a tendency to attach seawater or water to the fishing tackle due to rocks or the like. By exhibiting sufficient corrosion resistance even in fishing environments such as rocks in harsh environments where it is easy to scratch, it is possible to replace high-strength, ultra-lightweight magnesium-based materials with aluminum-based materials, zinc-based materials, and resin materials, and The inventors of the present invention have found that they can be used as materials for constituent members and have completed the present invention.

That is, the present invention provides a component for a fishing reel comprising a member main body made of an Mg alloy and an anticorrosion layer formed on the member main body.

In the present invention, the anticorrosion layer is preferably formed by anodic oxidation treatment, and a pore-sealing layer is preferably provided on the anticorrosion layer. The sealing layer is preferably formed by resin coating. Further, it is preferable that the member main body is molded by a die casting method using a Mg alloy.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A constituent member of a fishing reel of the present invention is characterized by including a member main body made of an Mg alloy and an anticorrosion layer formed on the member main body. In the present invention, as the Mg alloy, Al, Zn,
An alloy containing Mn or the like as an alloy element can be given.

Examples of the member main body include a reel main body of a fishing reel, a cover, a rotor, a handle, a frame of both bearing reels, and an outer plate. The member body is preferably molded by a die casting method using a Mg alloy. As the die-cast method,
A cold chamber method or a hot chamber method which is commonly used can be adopted. In particular, the hot chamber method is preferably used because the manufacturing cycle is fast.

In order to adjust the surface of the member body,
The member body may be subjected to mechanical surface treatment such as grinding, shot blasting, barrel polishing or the like, or chemical surface treatment such as solvent cleaning, alkali cleaning or acid cleaning.

In the present invention, examples of the method for forming the anticorrosion layer include chromic acid treatment, dichromate treatment, chemical conversion treatment such as stannate treatment, coating, and anodic acid treatment. In particular, as the anodizing treatment, HAE anodizing treatment capable of forming a dense anodized film, Dow
17 Anodizing treatment can be used. Since these anodizing treatments form an anodized film having a spinel structure, which is a dense and hard complex oxide structure, it is possible to impart extremely excellent corrosion resistance to the components of the fishing reel.

The thickness of the film (anticorrosion layer) formed by the anodizing treatment is preferably 5 to 20 μm, which shows stable performance (hard and dense). This is because the hardness of the coating is not sufficient when the thickness of the coating is less than 5 μm,
This is because if it exceeds 20 μm, cracks may occur during the film growth process.

It is preferable that the anodic oxide film formed on the member main body has a thicker thickness at a portion where different metal parts are in contact with or close to each other than other portions. For example, the thickness of the portion other than the portion in contact with the dissimilar metal parts is set to 5 to 20 μm, and the thickness of the portion in contact with the dissimilar metal parts is 10 to 20 μm.
Set to μm.

Incidentally, it is preferable to design the contacts during the anodizing treatment in a portion where there is no risk of corrosion. this is,
This is because the thickness of the anodic oxide film at the joint of each member becomes thin.

In the present invention, the sealing layer is preferably formed by resin sealing. As a method for sealing the resin, it is preferable to use resin coating such as electrodeposition coating or spray coating of low viscosity coating. In particular, it is preferable to use electrodeposition coating which can close small holes and fill small recesses, is easy in dimensional control, and has good film thickness uniformity.

Examples of paints used for this resin coating include epoxy paints, urethane paints, acrylic paints and the like. Of these, epoxy paint is preferable because it has good adhesion to the anodized film and the coating film is dense.

The low-viscosity paint used for the spray paint means a paint having a sufficiently low viscosity for filling the pores of the anticorrosion layer, which is an anodized film, and for filling the recesses. Therefore, the viscosity is appropriately adjusted depending on the thickness and surface condition of the anodized film. Examples of the method of adjusting the viscosity include a method of adjusting the solvent ratio in the paint.

The thickness of the sealing layer is 5 to 20 .mu.m, which shows stable performance (adhesion with an anodized film is good and dense).
m is preferable. This has a film thickness of 5 μm
If it is less than 4, the scratches of the sealing layer will reach the anodized film, and the anticorrosive effect will be reduced. Is.

In the constituent members of the fishing reel of the present invention, the sealing layer may be coated, if necessary. In addition, when forming the sealing layer, a decorative coating may be applied so that the sealing layer exhibits the decorative property.

Embodiments of the present invention will be specifically described below with reference to the drawings. (Embodiment 1) FIG. 1 is a schematic view showing constituent members of a fishing reel of the present invention. In the figure, 1 indicates a reel body (member body). On the side surface of the reel body 1, a side cover 2
Is attached. A rotor 3 is fixed to a rotation shaft (not shown) of the reel unit 1. A spool 4 is mounted on a spool shaft (not shown) of the rotor 3 so as to be able to move forward and backward with respect to the reel unit 1.

The rotor 3 is provided with two protruding arm portions 3a, and a bail support plate 5 is rotatably attached to the tip of each protruding arm portion 3a. A bail 6, which is a fishing line guide member, is attached to the bail support plate 5. In addition, a rotor 3 is provided on a side portion of the reel body 1 via a gear train train mechanism (not shown) in the reel body 1.

The reel body 1 is formed by die casting using a hot chamber of a Mg alloy containing 3.5 to 9.7% by weight of Al. This reel body 1
As shown in FIG. 2, has a structure in which the anticorrosion layer 12 is provided on the member main body 11, and the sealing layer 13 is further provided on the anticorrosion layer 12.

For the anticorrosion layer 12, the member main body 11 having contacts is put into a treatment liquid prepared by potassium hydroxide, potassium fluoride, sodium phosphate, aluminum hydroxide, potassium permanganate, etc. It is formed by performing HAE anodizing treatment under the condition that electricity is applied. Further, the sealing layer 13 is formed by performing electrodeposition coating using an epoxy paint. This sealing layer 13
Is formed in a state where the paint is filled in the holes 12a and the recesses of the anodized film forming the anticorrosion layer 12. Further, since the sealing layer 13 is formed by electrodeposition coating, its surface is flattened.

The weight of the component (reel body) of the fishing reel thus constructed was measured and found to be 32 g. In addition, when the corrosion resistance of the fishing reel components was examined by a salt spray test, no visually corroded parts were found, and the corrosion resistance was equivalent to that of conventional Al reel components, and it was extremely excellent. It was found to exhibit corrosion resistance.

As described above, the extremely excellent corrosion resistance is exhibited because the anticorrosion layer 12 is composed of an anodized film having a dense spinel structure, and the sealing layer 13 is excellent in adhesion with the anodized film. It is considered that this is because it is composed of a dense epoxy coating film, and moreover, the epoxy coating film is filled in the holes 12a and the recesses of the anodized film.
