Abstract

(57) [Abstract] [Purpose] The present invention is intended to prevent deterioration of a guide portion of a conventional fishing rod due to wear and a breakage of the hanging yarn due to the deterioration. [Structure] A titanium film 6 is formed on a surface of a guide portion 1 fixed to a fishing rod body 3 which is a fishing tackle by a dry plating method.
And a base layer of the silicon film or germanium film 7 and an upper layer of the carbon hard film 8 are formed. [Effect] Deterioration due to wear of the guide portion of the fishing tackle and breakage of the fishing line due to this can be significantly reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fishing rod, which is a fishing tackle.

[0002]

[Prior art]

 The guide portion fixed to the fishing rod, which is a tool, is a metal body fixed to the fishing rod main body and having a ring-shaped metal portion for guiding the fishing line.

The metal used for the guide portion is mainly stainless steel or aluminum subjected to alumite treatment.

How to use the guide part, etc., a fishing rod attached to one end side of the fishing rod (the side where the fishing rod is held by hand) This is to take out the thread, pass it through the ring-shaped metal part of the guide part, and let out the thread from the guide part at the tip of the other end of the fishing rod. Always in contact with metal parts.

[0005]

[Problems to be solved by the device]

 In the guide portion fixed to the fishing rod, which is a conventional fishing tackle, due to repeated use, the following problems occur between the fishing line and the guide portion. First, there was a problem that friction was generated at the contact point between the fishing line and the guide section due to repeated use, resulting in deterioration of wear of the guide section. On the other hand, there was a problem that the thread was cut due to the hanging thread hitting the deformed part due to wear deterioration of the guide part.

An object of the present invention is to solve the above-mentioned problems, to reduce friction coefficient as compared with a guide portion of a conventional fishing tackle, and to reduce wear deterioration at a contact point between a fishing line and a guide portion, and a degree of occurrence of deformation due to the wear deterioration. Is to be kept low to increase the durability of the guide portion and the hanging thread.

[0007]

[Means for Solving the Problems]

 The structure of the present invention to achieve the above-mentioned object is that the underlayer of the titanium film and the silicon film or the germanium film and the carbon hard film are formed on the surface of the guide portion fixed to the fishing rod which is the fishing tackle by the dry plating method. The upper layer is formed.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a guide portion and a fishing rod of the present invention. The guide portion 1 is fixed to the rod main body 3 at substantially equal intervals, and the shape thereof becomes smaller toward the tip portion 9 of the rod. Further, 4 is a reel, and 2 is a hanging thread fed from the reel 4.

FIG. 2 is an enlarged view of the vicinity of the contact portion between the guide portion and the fishing line, and the same reference numerals as those in FIG. The carbon hard film 8 of the present invention covers the entire ring-shaped metal part of the guide part 1.

Next, the film structure of the carbon hard film 8 of the present invention will be described. As shown in FIG. 3, a titanium film 6 and a silicon film or a germanium film 7 are applied to the base material 5, that is, the guide portion 1 made of stainless steel (SUS304) as a base layer in a thickness of 0.5 to 1.0 μm. As the upper layer, a carbon hard film 8 is applied in an amount of 1.0 to 1.5 μm.

Next, the method and procedure for forming the carbon hard film 8 in the present invention will be described below.

After cleaning the guide portion 1, it is set in a vacuum tank of a dry plating apparatus, a titanium film 6 is formed to a thickness of 0.1 μm by a dry plating method, for example, a sputtering method, and a silicon film is similarly formed on the titanium film 6. Alternatively, a germanium film 7 having a thickness of 0.3 μm is formed.

Thereafter, a carbon hard film 8 of 1.0 to 1 is formed on the silicon film or the germanium film 7 under the following conditions by using a dry plating method such as a P-CVD method (Plasma chemical vapor deposition method). 0.5 μm was formed. << Carbon hard coating >> <Forming conditions> Gas species: Methane gas Film forming pressure: 0.1 Torr High frequency power: 300 Watt Film forming rate: 0.12 μm / min Vickers hardness Hv: 3000 to 5000 Thus, the base material 5 A carbon hard film 8 having good adhesion and high reliability was obtained.

Next, in order to investigate the wear resistance of the carbon hard film 8 formed as described above, a sample in which a tin nitride (TiN) film was formed on the surface of stainless steel (SUS304), the same stainless steel (SUS304) was used. ), A nickel-plated film (Ni) and a chrome-plated film (Cr) are formed by wet plating, and a stainless steel (SUS304) sample is prepared, and the abrasion test of each sample is performed. The amount of scuffing of the film or base material due to wear was compared. The results are shown in the table below.

[Table 1]

From the above table, it can be said that the wear amount of the carbon hard film is 1/7 that of the stainless steel (SUS304) which is the material of the guide part of the conventional fishing gear, and therefore the carbon hard film is used for the guide part. By applying this, wear deterioration of the guide part can be prevented, and the yarn breakage accompanying it can be significantly reduced. The reason for providing the titanium film and the silicon film or the germanium film as the underlayer is to improve the adhesion, corrosion resistance, and abrasion resistance between the base material and the carbon hard film.

[0016]

[Effect of device]

 From the above graph, it can be said that the wear amount of the carbon hard film is 1/7 that of the conventional SUS material of the sling guide portion. Therefore, according to the present invention, by providing the carbon fiber hard film on the guide part of the sling, it becomes a product with extremely little wear deterioration, that is, excellent durability, which is extremely superior in quality compared to the conventional guide part. It can be said that it is. Further, since the deformation around the guide portion due to the wear deterioration can be extremely reduced, the breakage of the hanging yarn due to the deformation of the guide portion due to the wear deterioration can be remarkably reduced, and the durability of the hanging yarn can be remarkably enhanced.
