JP-A-60-227866

  In a tubular body such as a fishing rod disclosed in Patent Document 1, colored particles are shaved together by sharpening. For this reason, the decoration appearance modeled on the appearance of the tubular body cannot be stabilized, and it is difficult to create a tubular body such as a fishing rod having a stable decoration appearance (the same decoration appearance).

  This invention is made in order to solve such a subject, The place made into the objective is the manufacturing method of a tubular body and a tubular body which can stabilize the decoration external appearance modeled by the external appearance It is to provide.

  In order to solve the above problems, according to the present invention, a tubular body having a coating layer on the outside of a tubular body, and having a decorative portion on at least a part of the coating layer, the outer peripheral surface of the body and the tubular body A solid member having a hardness higher than that of the coating layer is disposed between the coating layer and the first layer disposed on the outer side of the main body, or part of the coating layer, and the solid member The coating layer disposed on the outside is sharpened, and a part of the solid member is exposed on the outer surface of the coating layer to form the decorative portion.

  In order to solve the above problems, according to the present invention, a tubular body having a coating layer on the outside of a tubular body, and having a decorative portion on at least a part of the coating layer, the outer peripheral surface of the body and the tubular body A solid member having a hardness higher than that of the coating layer is disposed between the coating layer and the first layer disposed on the outer side of the main body, or part of the coating layer, and the solid member The outer coating layer is sharpened with an abrasive that is softer than the solid member and harder than the coating layer, and a part of the solid member is exposed on the outer surface of the coating layer to form the decorative portion. It is.

  In order to solve the above-described problem, a method for manufacturing a tubular body includes a solid member disposed outside a tubular main body, a coating layer softer than the solid member disposed, and the coating layer from the outside of the coating layer. The decorative layer is formed by sharpening the coating layer with an abrasive that is harder than the coating layer and softer than the solid member to expose at least a part of the solid member from the coating layer.

  According to this invention, from the state where the solid member having a hardness higher than that of the coating layer is disposed on the outside of the main body and the solid member is covered with the coating layer, the coating layer on the outside of the solid member is removed from the solid member. The decorative part can be formed of the solid member, the coating film layer, and the main body by sharpening with a polishing body softer than the member and harder than the coating film layer to expose the solid member from the coating film layer. That is, even if the coating layer on the outer side of the solid member is sharpened, the progress of the sharpening can be stopped on the surface of the solid member. Therefore, it is possible to provide a tubular body and a method for producing the tubular body that can stably produce a decorative appearance that is shaped to the exterior.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
Examples of the tubular body of the present invention include a fishing rod, a golf club shaft, a tennis racket, and the like. In the following embodiments, a fishing rod will be used as an example.

A first embodiment will be described with reference to FIGS. 1 to 2C.
The fishing rod (tubular body) 10 is formed as, for example, a swinging mountain stream rod, a parallel-type spatula rod, a swing-out or a parallel-type rod, in which small-diameter rods are sequentially accommodated in a large-diameter rod. As shown in FIG. 1, a small-diameter rod tube 12 that is a tip rod in order from the tip, a plurality of middle rod tubes 14 that are, for example, two, and a main rod tube 16 having the largest diameter are gripped by the angler. A gripping portion 18 is formed on the buttock side of the main rod tube 16.

  The rods 12, 14, and 16 of the fishing rod 10 according to the present embodiment are a fiber reinforced prepreg (hereinafter simply referred to as a prepreg) in which a reinforced fiber such as a carbon fiber is impregnated with a synthetic resin such as an epoxy resin. Or it forms from the hollow soot tube which has the main body laminated | stacked by aligning and winding in the deflection | deviation direction inclined at an appropriate angle with respect to the axis. Instead of this, the small-diameter rod pipe 12 is not limited to such a hollow structure, but may be formed in a solid structure that can bend the fishing rod greatly. Of course, in addition to the swinging-out type, other appropriate joining types such as a side-by-side type or a seal-and-joint type can be adopted for such a soot tube.

  Further, when the fishing line is formed so as to guide the fishing line outside the fishing rod 10, a fishing line guide (not shown) for preventing the fishing line from adhering to the outer surface of the fishing tube is on the same side as the fishing reel. Then, it is fixed at a predetermined interval toward the tip of the fishing rod 10 and is fed out from the top guide fixed to the tip of the tip rod 12. Moreover, the inside of the fishing rod 10 can also be formed in what is called a through type into which a fishing line is inserted.

  As shown in FIG. 1, a decorative portion 20 is formed on a part of the outer peripheral surface of the middle rod 14 and the main rod 16 of such a fishing rod 10. In addition, it is also suitable that the decoration part 20 is formed in the whole outer peripheral surface of the middle wall pipe 14 and the main wall pipe 16. In the following description, it is assumed that the decorative portion 20 is formed on the intermediate tube 14.

  As shown in FIG. 2, the intermediate tube 14 includes a main body 32 in which a prepreg is wound and laminated as described above, and a coating layer provided on the outer side of the main body 32 (protection for protecting the outer side of the main body 32). Layer) 34. The coating layer 34 is not only located at the position where the decorative portion 20 formed at an appropriate position between the distal end and the proximal end of the intermediate tube 14 is formed, but also to the distal end side and the proximal end side of the intermediate tube 14. It is also suitable.

  The decorative unit 20 includes a coating layer 34 and a solid member 36. The coating layer 34 includes, for example, first to third layers (colored layers) 34a, 34b, and 34c. Among these, the first layer 34 a is in close contact with the outer peripheral surface of the main body 32. The second layer 34b is in close contact with the outer peripheral surface of the first layer 34a. The third layer 34c is in close contact with the outer peripheral surface of the second layer 34b. These first to third layers 34a, 34b, 34c are formed by layering, for example, an epoxy paint or a urethane paint. Further, a solid member 36 is disposed between the main body 32 and the first layer 34a. In other words, the solid member 36 is disposed outside the main body 32, and the outside of the solid member 36 is covered with the coating film layer 34 (first layer 34a). Each solid member 36 is formed of a material having higher hardness than the first to third layers 34 a, 34 b, 34 c, and the coating layer 34 is formed of a material softer than the solid member 36.

  In the present embodiment, the solid member 36 is formed in a substantially cylindrical shape (substantially disk shape) such as a tablet shape. Examples of the solid member 36 include metal materials such as iron, aluminum, titanium, gold, silver, and SUS, polyethylene terephthalate (PET), polypropylene (PP), polycarbonate (PC), acrylonitrile butadiene styrene (ABS), and the like. Various materials such as carbon, glass, silicon carbide and the like are used according to the desired decoration.

The coating layer 34 (first to third layers 34a, 34b, 34c) outside the solid member 36 shown in FIG. 2 (A) is sharpened to the state shown in FIG. 2 (B). At this time, a material that is softer than the solid member 36 and harder than the first to third layers 34a, 34b, and 34c is used as the polishing body (not shown). As the abrasive, for example, a non-woven fabric bonded and coated with abrasive grains such as aluminum oxide and silicon carbide (nonwoven fabric surface treatment material), and a sponge bonded and coated with abrasive grains such as aluminum oxide and silicon carbide (sponge) Abrasive materials, sandpaper (sandpaper), and a compound (abrasive particle) applied to a cloth (cloth) and polished (coated abrasive) are used.
For example, when urethane coating is used for the first to third layers 34a, 34b, and 34c of the coating layer 34, SUS is used for the solid member 36, and sandpaper is used for the polishing body, The first to third layers 34a, 34b, 34c outside 36 are gradually removed. Since the polishing body is softer than the hardness of the solid member 36, the polishing body reaches the upper surface of the solid member 36 (the position of the surface indicated by the symbol S in FIGS. 2A and 2B). The progress of sharpening is stopped. Therefore, as shown in FIG. 2C, the solid member 36 has a circular appearance, and the coating member contours of the layers 34a, 34b, and 34c are obtained around the solid member 36. That is, the decorative portion 20 is formed by the solid member 36 and the coating layer 34 around the solid member 36.

  The position of the upper surface of the solid member 36 is preferably above the position where the first to third layers 34a, 34b, 34c of the coating layer 34 are overlapped. That is, it is preferable that the thickness of the solid member 36 is thicker than the thickness obtained by superimposing the first to third layers 34 a, 34 b, 34 c of the coating layer 34. In this case, the coating layer 34 at a position away from the solid member 36 of the decorative portion 20 is prevented from being cut. That is, it is possible to reduce the amount of shaving other than the decorative portion 20 as much as possible.

As described above, according to this embodiment, the following effects can be obtained.
The coating layer 34 provided on the outside of the main body 32 is softer than the solid member 36, and the polishing body that sharpens the coating layer 34 is harder than the coating layer 34 and softer than the solid member 36. By polishing the upper surface (outer surface) of the solid member 36 buried between the outer peripheral surface of the coating layer 34 and the inner peripheral surface of the first layer 34c of the coating layer 34 with a polishing body, the solid member 36 is removed from the coating layer 34. It can be arranged at a position slightly higher than the outer peripheral surface or can be exposed in a substantially flush state. Therefore, by disposing the solid member 36 at a predetermined position on the outer periphery of the main body 32, the position of the decoration can be stabilized, and a plurality of solid members 36 having the same height can be appropriately disposed. The thickness of the film layer 34 can also be stabilized. For this reason, modeling of the decoration part 20 of the soot tube 14 can be stabilized. Then, by arranging the solid member 36 at a predetermined position, the tub tube 14 having the same decorative appearance can be stably produced.

  In addition, in this embodiment, since the columnar solid member 36 was arrange | positioned in the decoration part 20, although the circular external appearance shown in FIG.2 (C) was obtained, the solid member of various shapes can be used. Of course, appearances of various shapes can be obtained using solid members of various shapes. As another example of the solid member 36, for example, a spherical member, a string-like member (including a single wire and a stranded wire), or the like can be used. If the solid member 36 is, for example, spherical, the appearance obtained is a dot, and if it is, for example, a string, the obtained appearance is a line. Needless to say, if the solid member 36 is a columnar shape described in the present embodiment or a truncated cone shape described in the second embodiment to be described later, the obtained external appearance is planar.

  2A shows an example in which the solid member 36 is disposed directly on the outer side of the main body 32 (fixed by adhesion or the like), but the paint is applied as an undercoat between the main body 32 and the solid member 36. It is also preferred that a layer (coating layer) (not shown) is formed. It is also preferable that the solid member 36 is disposed between the first layer 34a and the second layer 34b.

  In the present embodiment, the decorative portion 20 is formed on the tub tube 14, 16. However, the decorative portion 20 is preferably formed on the tub tube 12, and the tub tube 12, 14 is also preferable. It is also preferable that a decorative portion 20 is formed on at least one of.

  Next, a second embodiment will be described with reference to FIG. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In addition, also about the effect of this embodiment, the description which overlaps with 1st Embodiment is abbreviate | omitted.

  Instead of the solid member 36 (see FIG. 2) described in the first embodiment, a solid member 38 is used as shown in FIG. The solid member 38 is formed in a substantially truncated cone shape having a substantially trapezoidal longitudinal section. The solid member 38 is disposed outside the main body 32 in the same manner as the solid member 36 described in the first embodiment.

  The inner peripheral surface of the first layer 34a is in close contact with the inclined surface 38a of the truncated cone-shaped solid member 38. The second and third layers 34 b and 34 c are also outside the first layer 34 a that is in close contact with the inclined surface 38 a of the truncated cone-shaped solid member 38. In addition, it is suitable for the first to third layers 34a, 34b, 34c of the coating film layer 34 to have a high light transmittance.

  As described in the first embodiment, the first to third layers 34a, 34b, 34c outside the solid member 38 are removed. At this time, the progress of sharpening is stopped at the position where the polishing body reaches the upper surface of the solid member 38 (the position of the surface S).

  Then, the first to third layers 34a, 34b, and 34c remain on the outside of the inclined surface 38a of the solid member 38. For this reason, the inclined surface 38a of the solid member 38 is pressed by the first to third layers 34a, 34b, 34c. That is, the first to third layers 34 a, 34 b and 34 c exhibit an anchor effect with respect to the solid member 38. For this reason, when the solid member 38 is sharpened, the solid member 38 is prevented from falling off between the first to third layers 34a, 34b, 34c. Further, even when the soot tube 14 having such a decorative portion 20 is bent, the solid member 38 can be prevented from falling off.

  Further, when a paint having high light transmittance is used for the first to third layers 34 a, 34 b and 34 c, the first to third layers 34 a, 34 b and 34 c are disposed outside the inclined surface 38 a of the solid member 38. The light is reflected between the slope 38a of the solid member 38 and the first layer 34a. Therefore, an excellent appearance can be formed by the reflected light from the inclined surface 38 a of the solid member 38. Further, in the vicinity of the outside of the inclined surface 38a of the solid member 38, light is also transmitted between the second layer 34b and the third layer 34c outside the inclined surface 38a of the solid member 38, and between the first layer 34a and the second layer 34b. Since it reflects, the light received from the circumference | surroundings of the decoration part 20 can give the impression that the fishing rod 10 has the outstanding decoration appearance with respect to the person who picked up the fishing rod 10, such as an angler. Thus, the decorative portion 20 of the present embodiment obtains a transmission effect along the thickness of the coating layer 34 around the solid member 38 (the film thickness of the first to third layers 34a, 34b, 34c). Can do.

For example, it is assumed that the coating layer 34 described in the first embodiment and the coating layer 34 of the present embodiment are formed to the same thickness using the same material. In this case, the distance (optical path) between the main body 32 around the solid member 36 described in the first embodiment (edge) and the first layer 34a of the coating layer 34 is the solid of the present embodiment. It is longer than the distance (optical path) between the member 38 and the first layer 34 a of the coating film layer 34. In other words, the light incident on the decorative portion 20 from the direction orthogonal to the axial direction of the tub tube 14 is reflected on the outer peripheral surface of the main body 32 through the first layer 34 a outside the solid member 36. This reflection surface is deeper than the reflection surface between the slope 38a of the solid member 38 and the first layer 34a of the present embodiment. At this time, the reflected light is not affected by the solid member 36 because the light does not enter the outer peripheral surface of the solid member 36 of the first embodiment. For this reason, the present embodiment can obtain a larger amount of reflected light affected by the solid member 38. The same can be said between the second layer 34b and the third layer 34c and between the first layer 34a and the second layer 34b. For this reason, compared to the case described in the first embodiment, the present embodiment has a better appearance of the fishing rod 10 than a person who has picked up the fishing rod 10 such as a fisherman. Can give an impression. That is, a larger decorative effect can be exhibited.
In the present embodiment, the solid member 38 is a truncated cone, but a polygonal truncated pyramid such as a triangular frustum or a quadrangular frustum is also suitable.

  Next, a third embodiment will be described with reference to FIG. This embodiment is a modification of the second embodiment, and the same members as those described in the second embodiment or members having the same functions are denoted by the same reference numerals, and detailed description will be given. Is omitted. In addition, also about the effect of this embodiment, the description which overlaps with 2nd Embodiment is abbreviate | omitted.

  In addition to the solid member 38 (see FIG. 3) described in the second embodiment, as shown in FIG. 4, there is a longitudinal section between the second layer 34b and the third layer 34c at predetermined intervals. A solid colored body (colored body as a solid member) 40 having a substantially semicircular surface and colored in a desired color is disposed. The solid colored body 40 is not required to be made of the same material as the solid member 38, but is formed to have substantially the same hardness as the solid member 38 or harder than the polishing body. Here, the solid members 38 are disposed at predetermined intervals, and the colored body 40 is disposed between the adjacent solid members 38 in a predetermined state. Adjacent solid members 38 are formed to have the same thickness.

  As described in the first embodiment, the first to third layers 34a, 34b, 34c outside the solid member 38 are removed. At this time, the polishing body is sharpened at a position reaching the upper surfaces of the plurality of solid members 38 (position of the surface S) and / or a position reaching the upper surfaces of the plurality of solid colored bodies 40 (position of the surface S). Progress is stopped. That is, when the height of the upper surface of the solid member 38 is higher than the height of the upper surface of the colored body 40, the surface S is the same surface as the upper surface of the solid member 38. On the other hand, when the height of the upper surface of the solid member 38 is lower than the height of the upper surface of the colored body 40, the surface S is the same surface as the upper surface of the colored body 40. Further, when the height of the upper surface of the solid member 38 is the same as the height of the upper surface of the colored body 40, the surface S is the same surface as the upper surface of the solid member 38 and the upper surface of the colored body 40.

  For this reason, for example, when the sharpening process (machining) is performed on a surface having different outer diameters on the front end side and the rear end side, such as the soot tube 14, the polishing body is solid member 38 and / or colored. The presence of the body 40 can prevent sharpening beyond a certain level. Therefore, for example, by using a planar polishing body, the amount of polishing between the adjacent solid members 38 can be stabilized, and the upper surface of the solid member 38 and / or the colored body 40 serves as a sharpening stopper, and the decorative portion It can prevent that the coating-film layer 34 of parts other than 20 can be scraped off, and can manage the thickness (film thickness) of a coating film. Furthermore, since the amount of polishing can be stabilized (fixed), modeling between adjacent solid members 38 (appearance around the solid member 38) can also be stabilized. Therefore, a fixed modeling is formed between the adjacent solid members 38.

  For this reason, predetermined stable modeling can be formed as the decoration part 20 whole of the tub tube 14. If it does so, the soot tube 14 stabilized with the high quality which performed the same modeling process can be provided.

  As described above, it is preferable that a plurality of the solid members 38 are disposed at a predetermined interval, for example. Then, like the rod 14 of the fishing rod 10, the outer diameter is different between the front end side and the rear end side, and the surface which is a tapered surface (inclined surface) is sharpened by machining. Since the body can form a desired shape (constant shape) around the solid member 38 due to the presence of the solid member 38, the amount of polishing between the solid members 38 can also be stabilized, so the thickness of the coating layer 34 (Film thickness) can be managed.

  Next, a fourth embodiment will be described with reference to FIG. This embodiment is a modification of the first to third embodiments, and the same members as those described in the first to third embodiments or members having the same functions are denoted by the same reference numerals. The detailed description is omitted. Note that the effects of this embodiment are also omitted from the description that overlap with the first to third embodiments.

In this embodiment, as shown in FIG. 5B, an example in which characters (for example, alphabet (Roman characters)) appear on the appearance of the fishing rod 10 will be described.
Instead of the solid member 36 (see FIG. 2) described in the first embodiment, a solid member 42 is used as shown in FIG. A solid member 42 is attached to the outer peripheral surface of the main body 32 via an adhesive (adhesive layer) 44. As shown in FIG. 5B, the solid member 42 is formed with characters (a variety of signs such as figures, symbols, and combinations thereof are allowed). The vertical cross section of the solid member 42 is formed in a trapezoidal shape in the same manner as the solid member 38 described in the second embodiment. That is, the solid member 42 has a slope 42a.

  And the coating-film layer 34 (1st layer 34a and 2nd layer 34b) is formed so that these adhesives 44 and the solid member 42 may be covered.

  In order to form the structure shown in FIG. 5A, the adhesive 44 is attached to one side which is the bottom surface of the solid member 42, and is extracted into a character shape. At this time, release paper (not shown) or the like is attached to the bottom surface of the adhesive 44. The release paper is removed from the adhesive 44 and the bottom surface of the adhesive 44 is attached to the outer peripheral surface of the main body 32. Thereafter, for example, first and second layers 34a and 34b which are coating layers are formed.

  As described in the first embodiment, the first and second layers 34a and 34b outside the solid member 42 are removed. The progress of sharpening is stopped at the position where the polishing body reaches the upper surfaces of the plurality of solid members 42 (position of the surface S). At this time, the outline of the coating film layer 34 (the first and second layers 34a and 34b) is formed around the character (solid member 42). As described above, when the solid member 42 (characters or complicated shapes) is formed with a contour corresponding to the thickness of the coating film around the solid member 42, a stable shape can be formed by making the amount of sharpening of the solid member 42 constant. it can.

  Therefore, if adjacent solid members 42 have the same thickness, a desired shape is formed around these solid members 42. Further, the amount of polishing between the adjacent solid members 42 can be stabilized, and the thickness (film thickness) of the coating layer 34 can be managed. Furthermore, since the amount of polishing can be stabilized (constant), modeling between adjacent solid members 42 can also be stabilized. Therefore, a predetermined modeling can be formed as the entire decorative portion 20 of the tub tube 14. If it does so, the soot tube 14 stabilized with the high quality which performed the same modeling process can be provided.

  In the present embodiment, as shown in FIG. 5B, an example in which alphabets such as “A”, “B”, and “C” are arranged in parallel as the solid member 42 of the decorative portion 20 has been described. If 42 itself is highly decorative, it is possible to form a more excellent and varied appearance. Of course, it is also suitable to use a decorated alphabet or the like.

  Note that various materials are used as the solid members 36, 38, 40, and 42 described in the first to fourth embodiments described above, but shells, metal pieces, metal wires, strings, tapes, and plate pieces. It is preferable that a chip or a chip is used. For the metal piece or the metal wire, for example, a metal material such as iron, aluminum, gold, silver, or SUS is used. For the strings and tapes, for example, fibers such as nylon fibers, acrylic fibers, and urethane fibers, and resin materials such as PET, PP, and PC are used. For the plate pieces and the chips, for example, resin materials such as PET, PP, PC, and ABS, carbon, glass, silicon carbide, and the like are used.

  Although several embodiments have been specifically described so far with reference to the drawings, the present invention is not limited to the above-described embodiments, and all the embodiments performed without departing from the scope of the invention are described. Including implementation.
