Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel for fishing, and more particularly, to a spinning reel for fishing with reduced weight and improved operability.

[0002]

2. Description of the Related Art A spinning reel for fishing is provided in front of a reel body having a leg (rod mounting portion) mounted on a fishing rod.
The structure is such that a rotor that rotates in conjunction with the take-up rotation operation of the handle is rotatably mounted, and a spool that moves back and forth by the take-up rotation operation of the handle is supported. A pair of support arms are attached to the rotor, and a bail support member that supports a bail is reversibly supported at one front of the pair of support arms.

Further, the spool is formed with a fishing line winding body portion around which the fishing line is wound, a front flange portion formed on the front side thereof to regulate the front side of the wound fishing line, and regulates the rear side of the fishing line. And a rear cylinder portion that covers the rotor. The bale rotates around the outer periphery of the spool with the rotation of the rotor by the winding operation of the handle, whereby the fishing line is moved back and forth through a fishing line guide (line roller) at one end of the veil. It is evenly wound around the winding body.

In the spinning reel for fishing configured as described above, the reel body and the rotor that rotates at a high speed have conventionally been mainly formed of an aluminum alloy.

[0005]

However, although aluminum alloys are sufficiently satisfactory in strength, they are heavier than resins and the like, so that the inertia force increases and the winding force increases accordingly. However, there is a problem that it becomes large and inferior in lightness. Further, there is also a problem that the old stop is difficult due to the inertia at the time of the winding rotation, and the winding is unnecessarily excessive.

Further, when the bail is lifted and the fishing line releasing operation is performed, a problem that the bale is erroneously inverted and returns to the fishing line winding state, and the fishing line is cut, is likely to occur. Furthermore, there are various problems that the rotational fluctuation of the rotor is easily felt and the winding rotational property is inferior.

On the other hand, in order to reduce the weight, spinning reels in which various members are formed of resin are frequently used. But,
A sufficiently satisfactory strength cannot be obtained with a resin material. That is, for example, if the rotor support arm is formed of resin, the rotation of the rotor causes the fishing line to be wound on a spool via a line roller, thereby reducing the configuration of a spinning reel.
At the time of winding the fishing line, the rotor support arm is deformed inward and comes into contact with the spool, which hinders the winding operation. Further, it has been pointed out in an actual fishing operation that there is a problem that the protruding rotor support arm is particularly damaged when subjected to an external force (drop of the spinning reel, collision with a rocky place, etc.).

According to the present invention, while ensuring a sufficient winding capacity,
It is an object of the present invention to provide a spinning reel for fishing with improved operability of winding and releasing a fishing line.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, a spinning reel for fishing according to the present invention comprises a reel body having a leg and a winding drive mechanism constituting a fishing rod mounting portion mounted on a fishing rod. A spool that winds a fishing line in front of a fishing line payout side and moves forward and backward by a winding rotation operation of a handle of the winding drive mechanism, a fishing line guide member that guides the fishing line to the spool, and supports the fishing line guide member. A fishing spinning reel provided with a support arm and a rotor that is rotated by a winding rotation operation of a handle, wherein the rotor is formed of metal,
The total weight of the rotor unit body constituted by the fishing line guide member, the support arm, and the rotor is set to 50 g or less,
In addition, the present invention provides a spinning reel for fishing, wherein the outer diameter of a front flange formed at the front of the fishing line winding body of the spool is 40 mm or more.

According to the spinning reel for fishing having such a configuration, the total weight of the rotor unit body is set to 50 g or less and the outer diameter of the front flange portion is set to 40 mm or more. It is possible to balance the winding capacity with harmony.

In particular, the total weight of the rotor unit is 50 g.
With the following, the inertia force of the rotor rotation can be reduced, so that a light winding rotation operation can be performed, and unpleasant rotation runout and excessive winding during the winding rotation operation are eliminated. In addition, various effects can be obtained such that erroneous return of the bail due to unnecessary rotation of the rotor during the discharging operation can be prevented. Further, by reducing the total weight of the rotor unit body, an effect of suppressing unnecessary weight deviation toward the front of the reel body can be obtained. That is, the front and rear weight balance with respect to the leg of the reel body is achieved, the sense of unity of the reel and the fishing rod is increased, and the operability of fishing and winding fish is further improved.

In the spinning reel for fishing of the present invention, it is preferable that the rotor is formed of a magnesium alloy having an anticorrosion layer on the surface. In this way, by forming the rotor from a magnesium alloy, the weight and strength of the rotor can be reduced, and unremovable trouble (spool contact phenomenon) due to deformation of the rotor support arm during heavy load winding can be solved. And it is possible to respond sufficiently even under severe conditions.

In addition, the rotor can be made lighter by reducing the thickness as much as possible while maintaining the required strength. Therefore, the spool can be easily made larger in diameter without lowering the operability. Sufficient winding capacity is secured, and the discharge performance can be improved.

Further, in the spinning reel for fishing of the present invention, it is preferable that the total weight of the entire reel including the reel body, the rotor unit and the spool is 210 g or less.

[0015] As the weight of the reel is reduced, it is possible to sharply adjust the position of the fish, and the accuracy of sensing is improved. Further, even if the fishing operation is performed for a long time, a comfortable fishing operation can be performed without feeling fatigue.

Further, in the spinning reel for fishing of the present invention, it is preferable that the reel body is formed of a magnesium alloy.

As described above, by forming the reel body from a magnesium alloy, the weight and strength of the reel body are achieved, the deformation of the reel body at the time of heavy load winding is suppressed, and the smooth winding by the handle is achieved. The take-up operation can be performed, and the durability of the drive unit inside the reel body is improved, and a good take-up operation can be maintained for a long period of time.

[0018]

Embodiments of the present invention will be described below.

In the spinning reel for fishing of the present invention, the spool diameter is increased, the weight of the rotor unit is reduced, and the strength of the rotor unit is increased in order to improve the winding and releasing operation of the fishing line while securing a sufficient line winding capacity. It is intended. That is, the total weight of the rotor unit body including the metal rotor is 5
0 g or less, and the outer diameter of the front flange formed at the front of the fishing line winding trunk of the spool is 40 mm or more.

In order to obtain such excellent performance of the fishing spinning reel of the present invention, it is particularly desirable that the rotor and the reel body are made of a lightweight and high-strength Mg alloy. When the rotor and the reel body are made of the Mg alloy, the thickness of these members can be reduced, and even if the diameter of the spool is increased, the weight of the entire reel can be reduced.

An anticorrosion layer is provided on the surface of each member made of the Mg alloy. In the present invention, Mg
Examples of the alloy include an alloy containing Al, Zn, Mn, or the like as an alloy element.

Further, the rotor and the reel body made of the Mg alloy are preferably formed by a die casting method or a thixo molding method.

As the die casting method, a cold chamber method or a hot chamber method which is usually performed can be employed. In particular, because the manufacturing cycle is fast,
It is preferable to use a hot chamber method.

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

In the present invention, the method for forming the anticorrosion layer includes chemical treatments such as chromic acid treatment, heavy chromate treatment, zinc phosphate treatment, manganese treatment, non-chromium / manganese treatment, stannate treatment, painting, and anode treatment. Oxidation treatment and the like can be mentioned. In particular, as the anodizing treatment, a HAE anodizing treatment and a Dow17 anodizing treatment capable of forming a dense anodized film can be used.

These anodic oxidation treatments are performed using a dense and hard Mg
Since an anodic oxide film having a spinel structure, which is a complex oxide structure, is formed with O, extremely excellent corrosion resistance can be imparted to the components of the fishing reel.

As a more excellent anodic oxidation method, there is a high voltage anodic oxidation treatment (for example, MAGOXID treatment). This high-voltage anodizing treatment is performed by applying a high voltage (for example, 20 μm) in an organic aqueous electrolyte (for example, sulfuric acid, phosphoric acid, aluminate, etc.).
(0 V or more).

The features of this method are the Dow 17 method and the HAE
Compared with the conventional anodic oxidation method such as the method, the coating composition contains more MgO components than spinel, so that corrosion resistance, abrasion resistance and adhesion are good. For this reason, scratches that reach the material are unlikely to occur, and contact corrosion with dissimilar metals is less likely to occur.

That is, an electrochemical corrosion test (DINSS5)
0918) and neutral salt spray test (DIN 5002)
After performing 1), according to the high voltage anodic oxidation method, Do
Compared to conventional anodic oxidation methods such as w17 method and HAE method,
It shows much better corrosion resistance, and abrasion test (rubber test) and adhesion test (punch test) were performed. The high voltage anodization method was replaced by the conventional anodization method such as Dow17 method and HAE method. In comparison, it showed much better wear resistance and adhesion.

Further, the anticorrosion layer formed by anodic oxidation has a large amount of MgO component that develops white, so that the appearance after the treatment becomes beautiful white, and without overcoating such as metallic coating.
A high quality appearance can be obtained only by performing the sealing treatment. Furthermore, since the base is white, it can be dyed in various colors with dyes and pigments.

The thickness of the film (corrosion protection layer) formed by the anodic oxidation treatment is preferably 5 to 20 μm, which shows stable performance (hard and dense). This is because if the thickness of the coating is less than 5 μm, the hardness of the coating is not sufficient,
If the thickness exceeds 20 μm, cracks may occur in the process of growing the film.

The anodic oxide film formed on the member main body is preferably made thicker at a portion where the dissimilar metal component is in contact with or close to the other component than at other portions. For example, the thickness of the portion other than the portion where the dissimilar metal parts contact is 5 to 20 μm.
And the thickness of the portion where the dissimilar metal parts contact is 10 to 2
Set to 0 μm.

It is to be noted that the contact at the time of the anodic oxidation treatment is preferably designed in a portion where there is no possibility of corrosion. this is,
This is because the thickness of the anodic oxide film at the joint of each member is reduced.

Next, specific examples of the fishing spinning reel according to various embodiments of the present invention will be described with reference to the drawings.
