DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod in which a plurality of fishing line guides are integrally formed on the inner surface of a rod pipe main body or a pipe member inserted and disposed therein.

[0002]

2. Description of the Related Art A through fishing rod is used because a fishing line is hardly entangled with the tip of the rod, but a fishing line guide is generally provided inside the through fishing rod to reduce fishing line resistance. If such a fishing line guide is formed separately from a pipe material such as a rod pipe, and then bonded and fixed, etc., the bonded portion is likely to peel off due to repeated bending of the fishing rod by fishing,
It is preferable in terms of durability that the guide is integrally formed during the heat molding of the tube material. As an integrated guide forming method, for example, a tape is wound around a cored bar so that the side portions overlap each other, a fishing line guide member is disposed in a concave portion of a step portion corresponding to the thickness of the tape, and a pipe line member is formed from thereabove. And heat-formed together. However, in such a forming method, there is a limitation because the height of the fishing line guide depends on the thickness of the tape. If the height of the fishing line guide is low, it is considered that a large number of fishing line guides are arranged and the interval between them is narrowed to prevent the fishing line from coming into contact with the inner surface of the rod pipe and generally reduce the fishing line resistance.

[0003]

However, since the fishing line resistance is approximately proportional to the length of contact with one fishing line guide multiplied by the number of fishing line guides (the sum of the contact lengths), In order to reduce fishing line resistance as much as possible,
It is not enough to simply prevent the rod from contacting the inner surface, and it is necessary to devise the contour of the fishing line guide.

Accordingly, the present invention reduces the fishing line resistance as much as possible in a through fishing rod in which a plurality of fishing line guides are integrally formed on the inner surface of a rod tube main body or a pipe member inserted and disposed therein. The purpose is to:

[0005]

SUMMARY OF THE INVENTION In view of the above object, according to the present invention, there is provided a fishing rod according to the present invention, wherein the inner surface of a rod pipe main body of a through fishing rod is provided.
The number of fishing line guides protrude integrally formed, the number of fishing line guides, the radius protrusion height from rod pipe main body inner surface, the fishing line through the guide vertices of the vertical lines and the rod to the rod tube body inner surface Within the range of the arc centered on the intersection with the inner surface of the pipe body ,

The maximum width of the main part of the fishing line guide faces the rod pipe main body.
The present invention provides a through fishing rod characterized by being integrally formed in the following manner. Here, regarding a plurality of fishing line guides, in the case of a spiral fishing line guide, even if it is a single spiral, if there are a plurality of spiral turns, it will have a plurality of fishing line guides. The same applies to claim 2.

[0006] In claim 2, formed to project integrally on the inner surface of the rod pipe main body <br/> of the fishing fishing rod, a number continuous helically have a serrated fishing line guide, from rod pipe main body inner surface At the point where the line having a height of half of the protruding height intersects the left and right contour shape lines, a first line perpendicular to the inner surface of the rod pipe main body is drawn on the short line side, and a second line contacting at that point on the long line side A line is drawn, and a point near the vertex of the fishing line guide is located outside a circle inscribed in a right triangle defined by the first line, the second line, and the inner line of the rod body. Provide fishing rods. In the tangent line on the long line side, even if the contact has minute irregularities, the tangent line is drawn in a shape uniform to the basic sawtooth shape.

According to the first aspect of the present invention, the projection height from the inner surface of the rod pipe main body is defined as a radius, and the rod pipe main body passes through the top of the fishing line guide.
Since at least the vicinity of the apex of the fishing line guide is located within the range of the arc centered on the intersection of the line perpendicular to the inner surface and the inner surface of the rod pipe main body , the vicinity of the top of the fishing line guide protruded compared to the arc shape. Therefore, the length of the fishing line in contact with the fishing line guide is shorter than when the top of the fishing line guide has the arc shape, and the fishing line resistance is correspondingly reduced.

In the second aspect, the vicinity of the top of the fishing line guide has a protruding shape as compared with the case of the circular shape inscribed in the right-angled triangle, and therefore, the length of the fishing line in contact with the fishing line guide is limited to the length of the fishing line. The guide top is shorter than in the case of this circular shape, and the fishing line resistance is correspondingly reduced.
According to a third aspect of the present invention, there is provided a through fishing rod according to the first aspect, wherein the top of the fishing line guide is formed with a smooth curve .
According to a fourth aspect, there is provided a through fishing rod according to the first or third aspect, wherein a resin portion is formed at a base of the fishing line guide . According to a fifth aspect of the present invention, the fishing line guide has a main body formed by a prepreg in which a fiber is impregnated with a resin, and the height of the main body is more than 1.3 times the width thereof. ,
4. A through fishing rod according to any one of 4 .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is a side view when the fishing rod according to the present invention is used, and FIG. 2 is a longitudinal sectional view when it is stored. A third middle rod 12 is attached to the former rod 10, a second middle rod 14 is attached thereto, a first middle rod 16 is attached to the second intermediate rod, and a head rod 18 is joined to the first middle rod 16 in a swing-out manner. ing. A top guide 20 is detachably screwed to the tip of the tip rod. The reel 24 is fixed to the reel leg fixing device 22 on the original rod 10, and a rod end part 28 is attached to the rear end. A fishing line introduction part 26 is formed at the tip of the third middle rod 12, and the fishing line 30 is introduced from the reel 24 into the rod tube and drawn out from the top guide 20. As shown in FIG. 2, a ball-shaped line stopper member 32 is attached to the fishing line 30 outside the top guide so that the fishing line remains outside the top guide in a closed state.

A holding portion 38 is formed at a rear portion of the top guide 20, and a stopper portion 34 and a holding portion 40 at a rear portion are provided outside a front end of the first middle rod 16, and similarly, a second middle rod 16 is provided. A stopper 36 and a rear holding part 42 are provided at the tip of the rod 14, and a holding part 44 is formed at the rear of the fishing line introduction part 26. The fishing line introduction part 26 may be formed in the original rod 10 or the like. The top guide 20, the stopper portions 34, 36, and the fishing line introduction portion 26 are formed such that the rod tubes 18, 16, 14, 12, which are respectively formed and mounted, are adjacent to the large diameter rod tubes 16, 14, 12, 10, 10. When it is stored in the box, it acts as a stopper that stops the part from being stored too much, leaving the knob part when pulled out.

[0011] Hollow plugs 18E, 16E, 14E and tail plugs 12E each having a ceramic guide ring are detachably attached to the rear ends of the rod pipes 18, 16, 14, 12 respectively. A space is left between the hollow plug 14E and the butt plug 12E, and the fishing line 30 is bent in a state where the fishing line 30 is inserted therein, and the direction of the fishing line 30 is changed at the rear end of the second inner rod 14 and bent. Can be freely inserted. In the figure, a part of the fishing line 30 is omitted. Therefore, when the fishing line is wound on the reel 24 in a state where each rod tube is housed, the fishing line can be wound freely unless the fishing rod is turned down, but may be accidentally turned down.
In this case, each rod pipe falls. In order to prevent this, the holding portions 38, 40, 42, and 44 are provided, and the rod tubes provided with the respective holding portions are lightly placed on the inner surface at the distal end of the adjacent large-diameter rod tube in which they are stored. It is pressed and held. Therefore, in the stored state, the fishing line 3
Each rod tube is prevented from coming out while winding 0,
Work becomes stable.

The rod pipes 14, 1 on the front side of the fishing line introduction section 26
A number of fishing line guides 46, which are spiral guides, are formed in the inside of the rods 6 and 18 so as to protrude from the inner surface of the rod pipe throughout the longitudinal direction.
The guide line 6 allows the fishing line 30 to be inserted with reduced line resistance. There may be an area where the fishing line guide does not exist. Hereinafter, the second middle rod 14 will be described as an example, but the same applies to the other rod pipes 16 and 18.

FIG. 3 is an enlarged sectional view of a plurality of fishing line guides 46 comprising the above-mentioned spiral guides in a direction transverse to the spiral direction. The point P0 and the point 46T pass through the vertex 46T of the fishing line guide 46, and center on the intersection P0 between the line L1 and the inner surface 14S orthogonal to the inner surface 14S of the rod tube main body 14.
Comparing the arc C1 having the radius H with the length H between the above and the fishing line guide 46, the fishing line guide 46 is contained within the arc C1 except for the base 46B which is a part of the lower part of the fishing line guide 46. That is, near the top of the fishing line guide that the fishing line contacts (hereinafter, referred to as
(Sometimes referred to as the top).

Although the contour shape including the top portion is formed by a smooth curve, an inclined side portion or the like may be formed by a straight line. Since many fishing line guides 46 are arranged at a small pitch in the rod pipe, the fishing line 30 is inserted in contact with the vicinity of the apex 46T of the many fishing line guides 46, but the top of the fishing line guide projects as described above. Since the curvature is larger than that of the circular arc C1, the contact length of the fishing line 30 is shorter than that of the case where the contour shape of the fishing line guide 46 is the circular arc C1, and the overall fishing line resistance is reduced.

The lower portion including the base portion 46B may fall within the arc C1. Further, in FIG. 3, the left and right sides are drawn in a symmetrical contour shape, but it is not necessarily required to be completely symmetrical as long as the top part falls within the above-described arc C1. Such a fishing line guide 46 can be integrally formed using a carbon fiber bundle or the like when the rod tube main body 14 is formed. Base 4
Reference numeral 6B denotes a body in which the impregnated resin of the rod pipe body flows and solidifies at the time of heating and firing. The main body part 46A including the top is formed of a prepreg obtained by impregnating a carbon fiber bundle with a resin, and the top is preferably resistant to abrasion. . Therefore, in addition to carbon fiber, the main body including the top is made of silicon carbide, alumina, boron,
It is preferable to form a prepreg impregnated with a synthetic resin by using a ceramic fiber bundle such as glass or a metal fiber such as stainless steel or titanium as a reinforcing fiber. Further, a water-repellent resin such as fluorine, a lubricating resin, a wear-resistant resin, or the like may be used as it is, or a fiber may be formed by impregnating another resin such as an epoxy resin.

The relationship between the width W of the main body 46A and the height (radius) H of the fishing line guide is preferably H> W, more preferably H> 1.3W. Fig. 4 shows a modified example 46 "of the fishing line guide cross section, in which the top is covered by a small convex portion 46C. Each convex portion 46C is formed by a smooth curve, and a fiber bundle such as carbon fiber. Since the fishing line 30 only contacts the tops of these projections, the contact length is further shorter than in the case of Fig. 3 and the fishing line resistance is reduced. The arc C1 ″ in the case where there is an uneven portion is the vertex of the convex portion having the highest height from the surface of the rod pipe main body, which is the vertex 4 in FIG.
Think of it as 6T. In such a case, as shown in FIG. 4, not all the projections 46C are necessarily included in the reference arc C1 ", and some projections may protrude from the arc. In this case, Also, the contact length of the fishing line 30 is shortened, so that the fishing line resistance is reduced.

FIG. 5 shows another example of the cross section of the fishing line guide, in which a main body 46A 'is embedded at a high position in a base 46B' made of synthetic resin or the like. This main body 46A '
May be a single fiber strip of metal, ceramics, synthetic resin, or the like. The base may not be made of a synthetic resin, but if it is formed of a soft member, it is possible to prevent stress from being concentrated at the joint with the rod pipe body 14 when the fishing rod is bent. Further, if the width of the base is widened and the thickness is gradually reduced like the foot of Mt. Fuji, the stress concentration can be further reduced. The extent of this skirt may be increased and connected to the base of the adjacent fishing line guide. When fluorine is used as an example of the soft member used for the base, the fluorine is distributed over the entire surface if formed by melting, rather than mixing fluorine particles. The fishing line resistance can be efficiently reduced when trying to contact the inner surface of the rod pipe between the guides.

The entire surface of the line guide, or at least the lower surface of the line guide, ie, a surface area Z such as the base 46B '.
1 is made highly water-repellent, and the area (the area between the adjacent fishing line guides) Z2 such as the surface of the adjacent rod pipe body is made hydrophilic to relatively improve the water repellency on the fishing line guide side. Since it is possible to prevent the fishing line from hitting the water droplets, it is possible to reduce the ratio of the fishing line hitting the water droplets. Further, the water droplets falling from the fishing line guide spread in the relatively low water repellent region Z2. Difficult to contact water film. That is, the fishing line resistance is reduced.

FIG. 6 shows an embodiment of a lightweight fishing line guide.
(A) is to reduce the weight by providing a through hole 46H at the base of the fishing line guide 46, and to the left and right direction in the figure (the front and rear direction of the rod pipe).
A water droplet is caused to flow and moved to drain water at a predetermined position. If a hollow portion (air pocket) is used instead of a through hole, only weight reduction can be achieved. (B), a mixture S1 of a silicon carbide fiber having a high wear resistance and a hollow resin fiber (or a hollow glass fiber) is provided at a top portion where the fishing line comes into contact, and a hollow fiber S2 is provided at an intermediate height portion; A foam material S3 is mixed in the base to reduce the weight.

FIG. 7 shows another example of the cross section of the fishing line guide. It is an example of a sawtooth-shaped fishing line guide in which left-right symmetry is largely broken, and is a cross-sectional view of a helically continuous fishing line guide 46 ′. A fishing line guide of such a shape is formed by winding a thick tape on a cored bar so that the side portions have an overlapping portion with each other, and rounding the corners of the resulting step portion to form a smooth fishing line guide. A thin sheet or the like is put on the wound tape, and a material such as a carbon fiber bundle for a fishing line guide is wound therefrom, and a prepreg for forming a rod pipe main body is wound thereon. By heating and firing to form an integral part of the rod tube body. These fishing line guides 4
6 ', like the fishing line guide 46, has a height of generally about 0.5 mm.

In FIG. 7, the inner surface 14S of the rod tube main body 14 is shown.
Intersecting points of a half line from the height and the contour shape line are P2 and P3. Point P2 is the intersection of the long side line (inclined line) of the sawtooth shape, and point P3 is the intersection of the short side line. At a point P2, a tangent line L2 is drawn. At a point P3, a perpendicular line L3 is drawn to the inner surface 14S, and a circle C2 inscribed in a right triangle formed by combining the inner surface 14S, the tangent line L2, and the perpendicular line L3 is considered.

Near the apex 46T 'of the fishing line guide 46',
That is, the top exists outside the circle C2. That is, the circle C
2 and has a large curvature. Therefore, when the fishing line is inserted, the length of contact between the fishing line guide 46 'and the fishing line is shortened, and the fishing line resistance is correspondingly reduced.

FIG. 8 shows a fishing line guide 4 of the form described in FIG.
This is an example of use of 6 ′, where the tip in the A direction is the tip of the rod tube main body 14. The rear side of the fishing line guide 46 'is a concave gentle slope 46
The front side is formed on a steep slope 46F. Therefore, when the fishing line is sent out, the resistance is small, and when the line is wound, water droplets adhering to the fishing line are handled, which is convenient. Since the gentle slope 46R is concave, FIG.
The length per line of the fishing line is smaller than that of the straight line shown in FIG. In addition, if the front steeply inclined surface 46F is made water-repellent, the water droplets handled at the time of winding hardly adhere to the fishing line, and thereafter, the fishing line can be prevented from coming into contact with the handled water droplets. In addition, the durability is improved by forming the top portion 46P that makes strong contact with the fishing line with a wear-resistant member such as ceramics. The fishing line guide 46 'is ring-shaped, but may be formed in a spiral shape.

As described above, the present invention relates to a through fishing rod in which a plurality of fishing line guides each having a sectional shape shown in FIGS. 3 and 7 are integrally formed on the inner surface of a rod tube main body or a pipe member inserted into the rod tube main body. Although it is a basic form, another fishing line guide may be combined as shown in FIG. That is, a fishing line guide 52 made of ceramics or the like is mounted on the inner surface of the fishing line insertion body 50 having a cylindrical outer shape, and the fishing line insertion body 50 having inner surfaces 50F and 50R whose front and rear sides are enlarged is inserted into the rod tube body 14, and the fishing line is inserted. Acts so as to pass through the center of the rod tube main body 14.

The fishing line inserts 50 are provided at various places, and a number of fishing line guides 46 of the above-described configuration are provided between them, to make sure that the fishing line contacts the inner surface 14S of the rod tube body 14. It is received at its top to prevent it, reducing its contact length to reduce fishing line resistance as much as possible. However, if the pitch of the fishing line guides 46 is too large, the fishing line may hit the inner surface of the rod tube body 14 between the fishing line guides 46. In order to prevent an increase in fishing line resistance in this case,
FIG. 9 shows an arrangement in which one or more small protrusions 54 are arranged between the fishing line guides 46 in an appropriate number to reduce the contact surface of the fishing line. The ridge 54 is a fishing line guide 4
The width may be larger or smaller than the fishing line guide 46, or may be the same. Further, the ridge 54 is formed by integrating a separate member with the rod tube main body 14, and has an inner surface 14
S may be formed in a wave shape.

By providing the three-stage guide in this way, the fishing line resistance can be effectively reduced. Further, in FIG. 9, the fishing line insert 50 is inserted into the fishing line guide 46, but may be inserted into a region where the fishing line guide does not exist so that the outer periphery contacts the rod tube main body inner surface 14S. Further, the same applies to the case where the fishing line guide 46 is the aforementioned fishing line guide 46 '. When the small protrusions 54 are not provided, the arrangement pitch of the fishing line guide 46 is preferably about 15 to 50 times the height of the fishing line guide 46. Preferably, 15 to
Approximately 30 times.

As described above, the base of the fishing line guide 46 (46 ') is covered with a water-repellent material such as silicon, or is formed of such a material, and the inner surface 14S of the rod pipe body between the fishing line guides is formed.
If it is made more water repellent, water droplets are prevented from adhering to the periphery of the fishing line guide, and furthermore, it spreads thinly on the inner surface of the rod tube body between the fishing line guides, preventing the fishing line from coming into contact with water droplets when the fishing line is inserted And the fishing line resistance is reduced. In addition, the inside surface of the rod is made water-repellent to make it difficult for water droplets to adhere to it, and the high (round) water droplets are made into a low water film to make the fishing line hard to contact, making them hydrophilic. Thus, the fishing line resistance can be reduced.

The spiral fishing line guide may be a right spiral or a left spiral, but is preferably a spiral in a direction perpendicular to the winding habit of the fishing line. If the height is formed so as to protrude 0.3 mm or more from the inner surface of the rod tube, the fishing line becomes less likely to contact the inner surface of the rod tube, and generally the fishing line resistance is reduced. Further, the maximum height is preferably 20% or less of the inside diameter of the rod pipe for easy cleaning, and is preferably not more than 1 mm for easy manufacturing. In manufacturing, for example, it is easy to wind a tape around a metal core so that the sides overlap each other, and to form a fishing line guide in a concave portion of a step portion corresponding to the thickness of the tape. Is limited by the thickness. Therefore, for example, it is good to set it in the range of 0.3 to 0.6 mm.

The smaller the pitch, the more difficult it is for the fishing line to come into contact with the inner surface of the rod pipe.
Preferably, it is 20 mm or less, but if it is too small, all the fishing line guides are connected and it is meaningless, the weight increases, and the influence on the bending rigidity of the fishing rod cannot be ignored. Therefore, for example, it is good to make it about 5 to 20 mm. Further, since the inner diameter becomes smaller as the rod tip becomes smaller, the pitch is preferably made smaller as the rod tip becomes smaller so that the fishing line does not easily come into contact with the inner surface of the rod pipe. Therefore, as shown in FIG. 2, the pitch of the second middle rod 14, the first middle rod 16, and the tip rod 18 is sequentially set smaller.

The (pitch / height) ratio is 15 as described above.
The number is set to 50 or more, preferably 15 to 30. At the tip of the fishing rod having a small inner diameter, the height is reduced, and accordingly, the pitch is reduced. In the rear part of the fishing rod having a large inner diameter, the height can be relatively increased, and accordingly, the pitch can be increased. That is, if the pitch is too large with respect to the height, the fishing line comes into contact with the inner surface of the rod pipe, and the fishing line resistance increases. If the pitch is too small, the weight increases and the influence on the bending rigidity becomes a problem. . Therefore, the ratio has an appropriate range, and was set to the above range. In such a range, even if the fishing line has some twist or line habit, the fishing line is hardly brought into contact with the inner surface of the rod pipe, and the fishing line is easily cleaned. In addition, it is easy to prevent water droplets from collecting between the fishing line guides. However, the pitch may be constant irrespective of the size of the inside diameter, and the height may be formed low at the tip having a small inside diameter in order to secure a fishing line insertion space.

The angle of inclination of the spiral fishing line guide is an angle close to the longitudinal direction of the rod (about 5 degrees) from the circumferential direction (90 degrees).
The angle can be arbitrarily selected, but water having a smaller angle than 45 degrees may facilitate the flow of water in the longitudinal direction of the rod. Further, the spiral may be interrupted, a large number of ring-shaped fishing line guides may be provided, and a part of the ring or the spiral in the circumferential direction may be missing.

Although each of the above embodiments can be used as a single embodiment, an arbitrary configuration in which the respective portions of each embodiment are combined can also be used. In the case where a pipe member having a large number of fishing line guides formed therein is inserted and arranged so as to be able to be taken out of the through fishing rod, the same description will be given if this pipe member is regarded as the rod pipe main body of the above embodiment. Becomes Further, in the above description, the case where the fishing line guide is formed integrally with the tube material has been described. However, an application in which the above-described fishing line guide is formed separately and later mounted in the tube material is also possible.

According to apparent the present invention from the above description, Oite even fishing line resistance is reduced as much as possible in any of claims.
