DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external type line guide for a fishing rod. More specifically, the present invention relates to a line guide including a frame attached to a rod body and a guide ring fitted to an annular ring holding portion of the frame.

[0002]

2. Description of the Related Art Recently, a fishing rod has been required to have a high taste and aesthetic appearance, and the appearance of the rod body has become truly fashionable and diverse. For example, the rod body is painted white,
Almost any color such as black, red, vermilion, pink, blue, yellow, green, gold, silver, etc. is used, and many of them are beautifully patterned with such paints. With the expansion of fashionability and high-grade orientation of fishing rods, high hobbies and aesthetics have also been required for line guides, which are a part of fishing rods. In particular, in the case of a large fishing rod with a big fish as a symmetric fish,
Conventionally, aesthetic appearance has been relatively neglected, but such fishing rods are also required to have a lightweight feeling and fashionability.

[0003] As one means for giving the line guide a decorative or luxurious feeling, it is necessary to give a desired color to the material of the guide ring or to select a material with a luxurious color. Have been done. For example, titanium nitride cermet has an elegant gold color,
It is often used for high-end fishing rods. However, among the materials suitable for the guide ring, there are surprisingly few materials having an excellent color, and also, in many cases, a desired color cannot be obtained even when a ceramic or the like is colored. In fact, the number of colors of the guide ring is unexpectedly small.

Therefore, it has been proposed to form a coating film having a desired color on the surface of the guide ring. For example, Japanese Patent Application Laid-Open No. 1-265841 discloses that the surface of a guide ring is coated with gold or silver.

[0005]

However, in the case of a guide ring, the line often rubs the surface of the guide ring so that the coated film is easily peeled off by the line. If the coating film comes off, not only will the appearance worse, but also the surface of the guide ring will be rough,
There is a serious problem that the line is easily broken. In particular, in the case of a line guide attached to or near the tip of a rod such as a top guide, when catching a prey, a line with sand or metal powder that has been picked up in water or the like comes first. Therefore, the peeling of the coating film becomes remarkable.

A line guide used for a larger fishing rod naturally requires a larger diameter guide ring. However, if a titanium nitride cermet or the like is used for such a large diameter guide ring, the cost is increased. Is very high.

Furthermore, there is a problem that a guide ring, especially a guide ring made of ceramic, has a minute concave portion on the surface. As is known, a ceramic guide ring is formed by putting a slurry in which raw material powder, a solvent, a binder, and the like are mixed into a casting mold, forming the slurry, drying it, and then sintering it. You. Such a process,
In particular, bubbles are inevitably mixed in the process of making mud, and since these bubbles remain as pinholes, even if the polishing process is finally performed, minute recesses due to the pinholes appear on the surface thereof. It is. Even if such a concave portion is minute, if the line made of nylon runs with high heat, the line is seriously damaged, and eventually the thread breaks.

[0008] The present invention has been made in view of the above-described conventional problems, and without impairing the slidability of a line.
It is an object of the present invention to provide a line guide that can provide a hobby and a sense of quality without increasing the cost so much.

Another object of the present invention is to provide a method of manufacturing a guide ring which can fill a concave portion on the surface of the guide ring by using the above-mentioned means for giving a taste and luxury.

In order to achieve this object, in the present invention, ceramic, metal, synthetic resin, and a composite material thereof are provided on a non-line contact area of the surface of the guide ring except for an area with which the line contacts during actual fishing. In which a coating film made of a material selected from the group of is formed.

Therefore, at least in a state where a large load is applied to the line, the line does not come into contact with the coating film, so that the coating film can be almost certainly prevented from being peeled off by the line. That also prevents the line from being cut. In addition, as a material of the coating film, by selecting a material having a color that harmonizes in design with the color of the guide ring, the color of the frame, or the color or pattern of the rod, etc., without incurring much cost, The line guide can be given a high taste and luxury.

[0012]

According to a third aspect of the present invention, there is provided a method for manufacturing a guide ring as described above, wherein a ceramic, a metal, a synthetic resin and a composite material thereof are formed on the entire surface of the guide ring.
A coating film made of a material selected from the group is formed, and then, during actual fishing, only the coating film in a line contact area where the line contacts is polished and removed. Therefore, the minute concave portions on the surface of the guide ring disappear by being filled with the material of the coating film, and the coating film formed in the line contact area is removed leaving a portion filling the concave portion.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the method for producing a fishing rod line guide and guide ring according to the present invention will be described below with reference to the embodiments shown in the drawings. 1 to 6 show a line guide for a fishing rod according to the first embodiment. 1 indicates a fishing rod. Reference numeral 3 denotes a rod body of the fishing rod 1, and a reel sheet 5 with a handle is mounted on the bottom of the rod, and a reel 7 is detachably mounted on the reel sheet 5. A large number of choke guides 9 are mounted on the outer surface of the rod body 3 in a line, and a top guide 11 is mounted on the tip of the rod body 3. In this specification, the term “choke guide” is used to mean a line guide other than the top guide.

The structure of each of the plurality of choke guides 9 is the same except that the size of each of the choke guides 9 becomes smaller toward the pole tip side.
It is composed of The frame 13 includes an annular ring holding portion 17, a tongue-shaped mounting foot 19, and a supporting leg 21 connecting the ring holding portion 17 and the mounting foot 19. This support leg 21 is substantially V-shaped,
The lower end is continuous with the rear end of the mounting foot 19, and the upper end is continuous with both left and right sides of the lower apex of the outer peripheral surface of the ring holding portion 17. The above-described portions of the frame 13 having such a shape are integrally formed by pressing a metal material such as titanium or stainless steel.

The guide ring 15 has a circular ring shape and is made of a material such as ceramic, cermet, or metal. The cross-sectional shape orthogonal to the circumferential direction of the guide ring 15 is not a perfect circle, but has a substantially kamaboko shape. That is,
The outer peripheral surface 23 of the guide ring 15 is flat and the inner peripheral surface 2
5 is a substantially semicircular arc. The arc shape of the inner peripheral surface 25 does not always consist of a single arc, but may consist of a plurality of arcs. A coating film 27 is provided in a limited area on the surface of the guide ring 15. This region and the coating film 27 will be described later in detail. The guide ring 15 is fitted inside and bonded to the ring holding portion 17 of the frame 13.

The choke guide 9 constructed as described above
Is attached to the rod body 3 by winding the binding thread 29 in a state where the mounting feet 19 are seated on the outer surface of the rod body 3, and the portion where the binding thread 29 is wound is made of a transparent urethane resin or epoxy. A coating agent such as a resin is applied.

The top guide 11 comprises a frame 31, a thin mounting pipe 33, and a guide ring 35. The frame 31 includes an annular ring holding portion 37, a bridge 39 extending from both left and right sides of the ring holding portion 37 and connected to an intermediate portion of the mounting pipe 33,
A support leg 41 extends from the lower top of the ring holding portion 37 and is connected to the front end of the mounting pipe 33. In the frame 31 having such a shape, the above-described portions are integrally formed by pressing a metal material such as titanium or stainless steel.
The guide ring 35 of the top guide 11 is also basically
It has the same shape as the guide ring 15 of the choke guide 9, and a coating film 27 is provided in a limited area thereof. This region and the coating film 27 will also be described later.

The top guide 11 has its mounting pipe 33
The rod 3 is attached to the rod 3 by inserting the tip of the rod 3 with the adhesive. Line 4 drawn from reel 7
3 is sequentially passed through each hole of a number of choke guides 9 and top guides 11.

The frames 13 and 31 are finally plated with a desired color. As a material for this plating, black chrome (black), chrome (silver) or gold is generally used, but gun smoke (grayish black), bronze color (brownish silver), matte silver, or the like is used. May be. Of course, it is not necessary to limit to these colors.

Specific materials for the guide rings 15 and 35 include, for example, silicon carbide (Sic), silicon nitride (Si3N4), zirconium oxide (ZrO2), and aluminum oxide (Al2O3).
Of course, it is not necessary to limit to these types.

The material of the coating film 27 is not limited to ceramic or metal, but may be a synthetic resin paint or the like. Also, this material may be selectively used having a desired color, but preferably, a material having poor fashionability is avoided as much as possible, and a color similar to the color of the guide rings 15 and 35 or It is good to choose a color with a beautiful contrast. For example, when this material is selected from metals and ceramics, if gold is desired, titanium nitride (TiN) or titanium nitride plus gold (TiN + Au) is used, and if gray is desired, titanium carbide (TiN) is used. It is preferable to use TiC), titanium carbonitride (TiCN), or the like. The selection of this color depends on the guide ring 1
It is more desirable to consider the balance with not only the colors 5 and 35 but also the design elements such as the paint color and the pattern of the rod 3.

As a matter of course, a coating method for forming the coating film 27 is selected according to a material of the coating, a desired form of the coating film, and the like.
As well as the coating method, almost all of various known gas phase methods collectively referred to as a so-called PVD method and a CVD method are possible. Among the various gas phase methods, the PVD method, particularly, the ion plating method has many advantages in terms of quality and manufacturing cost.

The area where the coating film 27 is formed on the guide rings 15 and 35 may be any area other than the area where the line 43 is in contact, that is, the non-line contact area. Here, the line contact area means an area where the line 43 comes into contact with the line 43 in a state where tension is applied to the line 43, such as when throwing or throwing a prey. Accordingly, the line contact area is not uniform due to the condition of the rod body 3 (deflection characteristic), the number of line guides, the position of the line guide on the rod body 3 and the like, but is as follows. The measurement test was able to find a reasonable range.

In this measurement test, tension is applied to the line 43 in a state where the rod body 3 is tilted forward by approximately 45 °, and the tension is increased until reaching a general maximum load applied to a fishing rod of this type. Go and line 4 in between
3 was measured for the minimum contact angle α (see FIGS. 4 and 6) with respect to the guide rings 15 and 35. Here, the contact angle α is the line 4 passing through the guide rings 15 and 35.
3 is an angle formed between the entrance side portion and the exit side portion.

As a result of this measurement test, in the guide ring 15 of the choke guide 9, the minimum contact angle α of the line 43 is approximately 135 ° when the rod 3 is a light action (soft tone), When No. 3 was a heavy action (hard tone), the angle was approximately 158 °. Also, in the guide ring 35 of the top guide 11, there was a large variation in the minimum contact angle α of the line 43. That is, when the tip is soft like an Isogami rod or the like, the direction of the top guide 11 changes following the direction of the line 43, so that the minimum contact angle α is often a large angle close to 180 °. In the case of a rod body 3 having a hard tip such as a trolley rod or a trolling rod, the minimum contact angle α of the line 43 is often about 60 °.

From the above results, the line non-contact area in the choke guide 9 is selected in the area where the line is not in contact when the contact angle α of the line 43 with the guide ring 15 is from 135 ° to 158 °. That would be good. In this case, with some margin, assuming that the contact angle α of the line 43 is 90 °, a region where the line 43 is not in contact is defined as a line non-contact region,
If the coating film 27 is provided only in this region, the contact of the line 43 with the coating film 27 can be more reliably avoided. Also, the line non-contact area in the top guide 11 should be selected according to the condition of the rod body to be mounted. Can be.

When the coating film 27 is provided only in the line non-contact area, the guide rings 15, 3
Depending on the relationship between the color of the coating 5 itself and the color of the coating film 27, a great design effect can be obtained. For example, when the color of the guide rings 15 and 35 is a dark color such as carbon black and the coating film 27 is formed of titanium nitride, the coating film 27 is conspicuous, so that the thickness of the guide rings 15 and 35 is thin in a distant place. Gives a visible and lightweight image. Further, for example, when the color of the guide rings 15 and 35 is white and the coating film 27 is formed of titanium carbide, the coating film 27 is inconspicuous. It is possible to obtain a fishing rod that is mostly white and unified.

Although the coating film 27 is provided only in the line non-contact area, the form does not need to be uniform as a whole. For example, it is conceivable that the coating has a so-called blurred form by decreasing the thickness of the coating or increasing the surface density as approaching the line contact area, or a form including a desired pattern or some identification element. It is also possible to do. In addition, the coating such as the shading can be performed not only by the coating method but also by the ion plating method.

Although the thickness of the coating film 27 cannot be specified unconditionally, the present inventors have tried several coatings within a range of about 0.3 to 3 microns.
As a result, all of the coating films were good in both peeling resistance and heat dissipation. However, considering the balance with cost, for example, in the case of the ion plating method, it was 0.1 mm.
A range of 5 microns to 1 micron appears to be sufficient.

FIG. 7 shows a modification 51 of the above-described guide ring.
It shows. The difference between the guide ring 51 and the guide rings 15 and 35 is a cross-sectional shape orthogonal to the circumferential direction of the guide ring. That is, as can be seen from the drawing, the cross-sectional shape of the guide ring 51 is such that a thickness of a certain thickness including the inner peripheral surface 25 protrudes from the remaining portion toward the axis of the guide ring 15. The front and rear width of the inner peripheral surface 25 is somewhat smaller than the front and rear width of the remaining portion.

In the guide ring 51 having such a shape, even if the contact angle of the line 43 becomes about 90 °, there is no possibility that the line 43 comes into contact with a region other than the inner peripheral surface 25. The coating film 27 can be provided in a wide area excluding the inner peripheral surface 25, so that the coating film 27 can be exaggerated. The guide ring 51 has a particularly useful effect when used as a top guide.

FIG. 8 shows a line guide 61 according to the second embodiment. This line guide 61 differs from the line guide 9 only in the position where the coating film is provided. Therefore, only the main parts are shown in the drawings, and the description will be made only for the above differences.

In the line guide 61, the coating film 27 (having a satin pattern in the drawing) is provided on the surface of the guide ring 15 'in addition to the line non-contact area, and the line with which the line 43 contacts during actual fishing. It is also provided in a small recess 63 (exaggerated in the drawing) in the contact area in an embedded manner. Therefore, in this line guide 61,
The coating film 27 provided in the line non-contact area can provide a high taste and a sense of quality, and the minute concave portions 63 on the surface of the guide ring 15 'are filled with the material of the coating film 27 and disappear. Therefore, the surface of the guide ring 15 'becomes smooth, and the occurrence of thread breakage can be suppressed only by the warpage.

Next, a method for manufacturing such a guide ring 15 'will be described (see FIG. 9). The base body 65 of the guide ring 15 'is formed by a known casting method, and is finally subjected to required finish polishing. Next, a desired coating film 27 is formed on the entire surface of the base body 65 thus formed (FIG. 9 shows this state).
Thereafter, the line contact area is polished. This polishing may be performed using, for example, the same polishing member 67 as the polishing member used for the finish polishing performed on the base body 65. By this polishing, the coating film 27 in the line contact area is polished and removed. As a result, in the line contact region, only the coating film 27 filling the concave portion 63 remains, and the surface of the base body 65 is exposed to the remaining portion.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Are also included in the present invention. In particular, the material and color of the guide ring shown in the embodiment, the material and color of the coating film and the like are only a few examples in carrying out the present invention, in the present invention,
Various other materials and colors can be selectively used. Further, the coating film is not necessarily formed uniformly over the entire surface, but may be in a form representing some pattern or identification element.

The shape and type of the line guide to which the present invention can be applied are not limited to those shown in the embodiment. It can be widely applied to fishing rod line guides. The line guide has a direct fitting type in which the guide ring is directly fitted to the frame, and a so-called shock ring type in which a protective ring made of synthetic resin, brass, or the like is interposed between the frame and the guide ring. However, it goes without saying that the present invention can be applied to the latter type.

[0038]

As is apparent from the above description, according to the present invention, at least in a state where a large load is applied to the line, the line does not come into contact with the coating film. Stripping by the line can be almost certainly prevented, and this also prevents the line from breaking. In addition, as a material of the coating film, by selecting a material having a color that harmonizes in design with the color of the guide ring, the color of the frame, or the color or pattern of the rod, etc., without incurring much cost, The line guide can be given a high taste and luxury.

In the line guide according to the present invention, when the line passed through the guide ring is wound so as to form a 90 ° angle between an inlet side portion and an outlet side portion with respect to the guide ring, the line is formed. A region other than the contacting region is a line non-contact region, and a coating film is provided in this region. In line guides other than the top guide, as long as the fishing rod is used in normal use, the wrapping angle of the line around the guide ring will not be less than 90 °, so the line will come into contact with the coating film. Can be more reliably prevented.

[0040] In the line guide wearing the manufactured guide ring by gas Idoringu manufacturing method according to claim 3, not only can provide high hobby and luxury to the line guide, the guide ring Since the minute concave portions existing on the surface are filled with the material of the coating film and disappear, the surface of the guide ring becomes smooth and the occurrence of thread breakage can be suppressed accordingly.
