Description

The present invention relates to a fishing line guide and a fishing rod equipped with the fishing line guide.

Conventionally, fishing rods to which various fishing reels, such as spinning reels and double-bearing reels, can be attached are known. They are installed at predetermined intervals in the direction. Usually, a fishing line guide has a fishing line insertion portion (a guide ring holding portion to which a guide ring is attached) through which the fishing line is inserted, a guide leg fixed to the rod of the fishing rod, and a connecting portion connecting the fishing line insertion portion and the guide leg. It is configured with. Further, such a fishing line guide is formed in a plate shape from metal, synthetic resin, or fiber-reinforced resin (see FIG. 8 of Patent Document 1). It is fixed to the rod by threading and applying resin.

By the way, the plate-shaped fishing line guide as described above can be integrally formed by, for example, injection molding a ceramic material. A fishing line guide integrally formed of a ceramic material in this way has sufficient hardness and can be made lighter. In particular, the ceramic material has good slidability of the fishing line, so that it is not necessary to attach a guide ring to the fishing line insertion part, and it is possible to effectively reduce the weight.

However, the ceramic material has a weak impact strength, and may be damaged if impacted by other objects during actual fishing or handling. Therefore, when formed in the same size as a general metal fishing line guide, the impact strength is low, and as a result, it is necessary to increase the thickness of the shape. If the thickness of the fishing line guide is increased in this way, air resistance is likely to be received, which reduces the operability of the fishing rod and makes it look heavy.

The present invention has been made in view of the above-mentioned problems. Even if a ceramic material is used to form a fishing line guide of the same size as a metal guide, the required impact strength is provided and air resistance is received. To provide a fishing line guide that is difficult to use and looks light, and a fishing rod equipped with such a fishing line guide.

In order to achieve the above object, a fishing line guide according to the present invention comprises a guide leg that is fixed to a rod, a fishing line insertion section through which a fishing line is inserted, and a fishing line insertion section that rises from the guide leg. and a connecting portion that connects to the guide leg, and is configured in a plate shape integrally formed of a ceramic material, and a thick portion that protrudes toward the tip side of the guide leg is formed near the fixed portion of the guide leg. Characterized by

Since the fishing line guide having the structure described above is integrally formed of a ceramic material, it is possible to reduce the weight of the fishing line guide, and it is not necessary to attach a guide ring to the fishing line insertion portion. In addition, when the fishing line guide receives an impact from another object, the portion where the guide leg is fixed is likely to be damaged due to the action of a large load. By forming the portion, even if the fishing line guide has the same size as the metal guide, it is possible to efficiently secure the same impact resistance strength. In addition, since the body portion of the fishing line guide is not thickened more than necessary, it is less susceptible to air resistance and does not give an impression of being heavy.

The present invention also provides a fishing rod equipped with the fishing line guide described above.
Such a fishing rod is equipped with a plurality of fishing line guides that efficiently increase the impact strength without increasing the weight as described above, so that the weight of the fishing rod as a whole is not increased. For this reason, the operability does not deteriorate and the appearance does not give the impression of being heavy.

According to the present invention, even if a ceramic material is used to form a fishing line guide of the same size as a metal guide, the fishing line guide has the required impact strength, is less susceptible to air resistance, and looks light in appearance. And a fishing rod equipped with such a fishing line guide is obtained.

FIG. 1 is a diagram showing one embodiment of a fishing rod according to the present invention.
A fishing rod 1 shown in FIG. 1 is constructed in a draw-out type in which a middle rod 5 and a tip rod 7 are housed in a base rod 3, which are sequentially drawn out and spliced together. Each pole is configured as a tubular body, and is produced by, for example, winding a fiber-reinforced resin prepreg sheet in which reinforcing fibers are impregnated with a synthetic resin. A tubular body made of such a material is produced by a known manufacturing method, and the rod constituting the fishing rod of the present invention may have a solid structure other than such a tubular body structure. In addition, the number of rods and rods housed inside the base rod 3 (the number of jointed rods) is arbitrary, and the joint method may be a parallel joint type, spigot joint type, etc., in addition to the draw-out type. Also good. Also, the fishing rod may be a single rod instead of joining a plurality of rods.

A reel seat 9 having a reel leg mounting portion is arranged on the base end side of the base rod 3 . The reel seat 9 is provided with a fixed hood and a moving hood on both sides of the reel leg mounting portion in the axial direction. By moving in the axial direction, the reel leg is clamped onto the reel leg rest. The moving hood may be arranged on either the tip side or the base end side, and both sides may be configured as moving hoods.

Fishing line guides 10 and 10A for guiding the fishing line are attached to the base rod 3, the middle rod 5 and the tip rod 7 (the fishing line guide 10A is a top guide). A plurality of fishing line guides 10 are arranged on the surface of each rod at predetermined intervals along the axial direction. These fishing line guides 10 are of a type that is fixed by a fixing method as described later (fixed guide), and of a type that is slidable along the rod surface when the rod is stored (floating guide). )It is included.

Next, the configuration of the fishing line guide 10 attached to the above-described fishing rod will be described with reference to FIGS. 2 to 6. FIG. These figures show fixed guides that are fixed to the surfaces of the rods, and the attachment position to each rod is the front end side. Therefore, the size and the like are appropriately changed according to the outer diameter of the rod to be attached.

The fishing line guide 10 of this embodiment includes a guide leg 11 extending in the axial direction of the rod to which it is attached, a fishing line insertion portion 13 through which the fishing line is inserted, and an end portion of the tip side of the guide leg 11 that rises from the tip side of the fishing line. A connecting portion 15 connected to the insertion portion 13 is provided, and these are formed in a flat plate shape. The flat plate-shaped fishing line guide 10 having such components is made by pulverizing a ceramic material such as alumina, aluminum nitride, silicon nitride, silicon carbide, silica, or zirconia into powder and injection molding the powder. integrally molded.

Further, the fishing line guide 10 of the present embodiment has a single-leg structure in which the guide leg 11 extends in the axial direction on the base end side. It has a structure in which a fishing line inserting portion 13 having a circular opening 13A is provided on the upper end side of the connecting portion 15 . Since the fishing line guide is formed of the above-described ceramic material, the fishing line insertion portion 13 does not need to be fitted with a guide ring for enhancing the slidability of the fishing line.

In the configuration described above, the guide leg 11 is a region that is fixed to the rod 5 (see FIG. 7). The connecting portion 15 is defined as a region above the inflection point P1 where the rod surface (horizontal plane P) begins to curve upward when viewed from the side with the fishing line guide fixed to the surface of the rod. Define. Further, the fishing line insertion portion 13 is defined as an area above the lowermost position P2 in the circular opening 13A. Therefore, when the connecting portion 15 is viewed from the side, the ridgeline 15A on the lower surface side (rod tip side) is curved, and the ridgeline 15B on the upper surface side (base end side) is similarly curved (the connecting portion is It has a substantially uniform thickness).
In the example shown in FIG. 3, the inflection point P1 of the ridge line 15A is located at a position slightly raised from the lowermost end (horizontal plane P) of the guide leg 11. The ridgeline 15A may extend to the lowest end of the guide leg 11 depending on the shape of the . That is, the inflection point P1 of the lower ridgeline 15A that defines the connecting portion 15 may be present at the lowest end (horizontal plane P) of the guide leg 11 .

As described above, the fishing line insertion portion 13 is integrated with the connecting portion 15 , and the connecting portion 15 is formed so as to bend and rise from the guide leg 11 . In this case, although there is no particular limitation on the rising angle α of the rod tip side surface 15C of the connecting portion 15 with respect to the guide leg 11, the fishing line can be smoothly guided and the fishing line can be looped. It is preferably formed in the range of 30°≦α≦85° so that even if it gets entangled, it can be easily removed. In addition, the surface 15C of the connecting portion 15 in this embodiment is formed flush with the rod tip side surface 13C of the fishing line insertion portion 13, and forms a surface Pd that defines the rising angle α.

A thick portion is formed in the fishing line guide 10 so as to improve impact strength. As described above, since the fishing line guide 10 is made of a ceramic material, there is a possibility that the fishing line guide 10 may be damaged when receiving an impact. In the shape of the present embodiment, the portion where the greatest load acts is the portion where the guide leg 11 is fixed, particularly the portion where the guide leg 11 moves upward while curved to the connecting portion 15 (inflection point portion). is subjected to a large load (bending stress).

In the present invention, a thick portion is formed in the vicinity of the fixing portion of the guide leg 11 so as to protrude toward the rod tip side, thereby enhancing the reinforcing effect. That is, the conventional plate-shaped fishing line guide forms a connecting portion by gradually curving and rising at the front end position of the lower surface of the guide leg (the lower surface in contact with the rod). ) are susceptible to damage upon impact. For this reason, a thick portion is formed so as to protrude from the vicinity of the fixing portion of the guide leg 11 toward the fishing line insertion portion 13 toward the rod tip side.

The thick portion of the present embodiment is constituted by a rib 20 protruding toward the rod tip side and having a predetermined width and height so as to reinforce the connecting portion 15 . As shown in FIG. 3, the rib 20 is formed so as to protrude from the ridge line 15A of the connecting portion 15 toward the rod tip when the fishing line guide is viewed from the side. 15 is integrated with the face 15C. That is, the protruding side end face (rod tip side end face) 20A of the rib 20 of the present embodiment is arranged so as to be flush with the surface 15C of the connecting portion 15 and the rod tip side surface 13C of the fishing line insertion portion 13. formed.

In general, the fishing line guide 10 of the type described above has a large deflection in the vicinity of the fixed portion from the guide leg 11 to the connecting portion 15 (the curved portion transitioning from the inflection point P1 to the connecting portion 15) when the fishing line is caught. A load (bending stress in the clockwise direction in FIG. 3) acts, but by forming the rib 20 in this portion, an effective reinforcing effect can be obtained. That is, it is possible to improve the impact strength of the ceramic material that is the injection molding material.

The rib 20 is preferably formed on the rod tip side surface 15C of the connecting portion 15 in the area transitioning from the guide leg 11 of the fishing line guide to the fishing line insertion portion 13. Further, as shown in FIG. It is preferable to form it in the central portion of the rod tip side surface 15C of the connecting portion 15 . That is, the rib 20 (thick portion) may be formed over the entire surface 15C on the rod tip side, but as shown in FIG. It is possible to efficiently enhance the reinforcing effect without doing so. In this case, the upper end position 20a of the rib 20 may be positioned at the circular opening 13A of the fishing line insertion portion 13, but a particularly large load does not act (a large impact does not act) in the vicinity of the circular opening 13A. Therefore, as shown in FIG. 5, it is sufficient to form the connection portion 15 up to a substantially intermediate position.

Further, as shown in FIG. 3, the rib 20 is formed to a height that does not protrude from the rod tip side surface 13C of the fishing line insertion portion 13 toward the rod tip side, that is, does not protrude from the surface Pd toward the rod tip side. preferably. This is because if it is formed too high (thick), the rigidity distribution will change significantly, and the strength may rather decrease. Also, if the rib 20 is high, it is likely to receive wind resistance and the operability of the fishing rod is reduced.

5 and 6, the width W of the rib 20 is formed to have a uniform width in this embodiment, but the width W of the rib 20 is widened on the fixed side with respect to the rod, and is widened toward the fishing line insertion portion side. It is preferably formed to be narrow. By configuring in this way, an efficient reinforcing effect can be obtained without increasing the weight, and furthermore, a larger load can be endured without stress being concentrated in one part.

Further, the height H of the rib 20 is preferably formed so that the fixed side with respect to the rod is higher and the rib 20 is lower toward the fishing line insertion portion 13 side. By configuring in this way, the strength can be efficiently improved without concentration of stress in one part, and since the structure in which the width W changes creates a draft taper, molding can be easily performed. become. In addition, since the upper end side of the rib 20 is less susceptible to wind resistance, it is possible to prevent deterioration of the operability of the fishing rod.

A through hole 22 is preferably formed in the rib 20 . As shown in FIG. 3(a), the through hole 22 of the present embodiment is formed on the side of the fixing portion around which the fixing string 50 (see FIG. 7) is wound around the guide leg 11. As shown in FIG. By forming the through hole 22 at such a position, when the fishing line guide 10 is fixed to the rod, the line 50 to be wound can be inserted and pillow-wound, and the fishing line can be wrapped in the fixed state. It is possible to prevent the guide from coming off. Further, since the weight can be reduced by forming the through-holes 22, a plurality of them may be formed, and some or all of them are configured as recesses instead of through-holes. It can be. The size (inner diameter) and shape of the through-hole are not limited. For example, a through-hole 22A shown in FIG. It is possible to modify it appropriately, for example, to form it in a narrow shape.

As shown in FIG. 3, an end surface 20A of the rib 20 on the protruding side (end surface on the rod tip side) is formed flush with the surface 15C of the connecting portion 15 and the surface 13C of the fishing line insertion portion 13 on the rod tip side. The end surface 20A thereof is bent by approximately 90° and connected to the lower end surface 20B which abuts on the surface of the fixed rod. In this way, when the fishing line guide 20 is fixed to the rod, the lower end face 20B of the rib 20 abuts against the surface of the rod, so that even if a large bending stress acts on the fishing line guide, it is difficult to wobble or deform. It becomes possible to maintain a stable fixed state. That is, when the conventional fishing line guide in which the rib 20 is not formed is fixed to the surface of the rod, the fixed state of the fishing line guide is changed because the gap between the curved connecting portions is filled with fixing resin. However, the presence of the ribs 20 in such a gap stabilizes the fixed state of the fishing line guide, and the appearance deteriorates. Gone.

Further, the lower end surface 20B of the rib 20 may be extended in the axial direction as it is and integrated with the guide leg 11 so as to be a fixed portion that abuts on the surface of the rod. In this case, as shown in FIGS. 5 and 6, it is preferable to form a groove 24 extending along the axial direction of the rod in the portion fixed to the surface of the rod.

In addition, since the fishing line guide 10 of the present embodiment is difficult to come off and the fixed state can be stabilized due to the above-described configuration, the guide leg 11 can be lightened by thinning the tip side 11A thereof. It is possible. Furthermore, as shown in FIG. 2, by forming a large number of polygonal concave portions 15a in the connecting portion 15, weight reduction can be achieved. That is, according to the fishing rod in which a plurality of fishing line guides 10 having the above-described configuration are installed on the rod, the weight can be reduced, the operability can be improved, and the appearance does not deteriorate.

Next, with reference to FIG. 7, a method for fixing the fishing line guide 10 having the above configuration to the surface of the rod (in this case, the middle rod 5) will be described.
When fixing the fishing line guide 10 to the surface of the rod 5, the guide leg 11 is placed on the surface of the rod 5 and the fixing line 50 is wound around it. After the thread 50 is wound, a fixing resin is applied from the surface of the thread 50 to stabilize the fixed state.

When the line 50 is wound, it can be threaded through the through holes 22 formed in the ribs 20 and pillow-wound, so that the dropout strength of the fishing line guide can be improved while improving the impact strength. In this fixing work, with the conventional fishing line guide, resin enters the gap between the surface of the fishing line and the rod, resulting in poor workability. become. In addition, since the resin enters the through-hole 22 and an anchor effect is obtained with the surface of the rod, the fixing strength is improved and the fixed state of the fishing line guide is stabilized.

Furthermore, as shown in FIG. 7(b), when the lower surface (guide leg) of the rib 20 is brought into contact with the surface of the rod, the contact position 20P with respect to the rod is two by forming the groove 24 in the rib 20. It becomes a point contact, and it becomes possible to stabilize the fixed state.

The present invention is not limited to the above-described embodiments, and various modifications are possible. A configuration example of the modified example will be described below.
In describing various modifications below, the same reference numerals are given to the same constituent elements as in the above-described embodiment, and detailed description thereof will be omitted.

As shown in this modified example, a plurality of uneven portions 16 (retaining structure) may be formed along the axial direction on the surface of the guide leg 11 where the thread 50 is wound. The uneven portion 16 may be formed by continuously forming concave portions 16a as shown in (b), or may be formed by continuously forming convex portions 16b as shown in (c). can be

By forming such an uneven portion 16, it becomes possible to prevent the fishing line guide from slipping off due to the line entering the recessed region when the line is secured.
It should be noted that the method of forming the uneven portion can be modified in various ways, and the retaining structure may be one in which the surface is roughened or knurled or the like is formed.

FIG. 9 is a diagram showing a second modification of the fishing line guide, and is a plan view of the guide leg portion.

As described above, the ribs 20 may be integrally formed with the guide legs 11 so as to be wound on the surface of the rod and rod. A configuration may be adopted in which the rear surface is brought into contact with the surface of the rod and fixed as it is.

In such a configuration, it is preferable to configure the guide leg 11 with a curved surface along the surface of the rod. By forming such a curved surface, as shown in FIG. 7, it is possible to make two-point contact with the rod surface, thereby improving the fixing strength and stabilizing the fixed state of the fishing line guide.

FIG. 11 is a diagram showing a fourth modification of the fishing line guide, (a) being a perspective view and (b) being a side view.
The fishing line guide 10 of the above-described embodiment has a single-leg structure in which the guide leg 11 extends toward the base end in the axial direction of the fishing rod. Alternatively, the fishing rod may have two legs extending on both sides in the axial direction, and the fishing line insertion portion 13 may stand upright. In such a fishing line guide structure, the ribs 20 may be formed only on one of the guide legs, but it is preferable to form the ribs 20 on the opposing regions of both guide legs 11 respectively. . Furthermore, as shown in (c), the fishing line insertion portion 13 may be configured to be inclined and raised.

12A and 12B are diagrams showing a fifth modification of the fishing line guide, where (a) is a perspective view and (b) is a side view.
In the above-described embodiment and modification, the connecting portion 15 is formed in a plate shape, but the connecting portion may have a frame structure extending from both sides of the fishing line insertion portion 13 to the guide leg 11 . In this way, even if the fishing line guide has a partial frame structure, by forming the ribs 20 that become the above-mentioned thick portions on the frame portion (each frame 15F), even if the ceramic material is used, the impact is minimized. Strength can be improved.

FIG. 13 is a diagram showing a second embodiment of a fishing line guide, and is an enlarged view showing a fishing line guide (tip guide) attached to the tip rod rod 7 shown in FIG.

The fishing line guide 10A is press-fitted into the tip rod rod 7 and fixed by adhesion. Forming the through holes 22 in the ribs 20 provides an anchoring effect and can increase the adhesion strength.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified in various ways.
In the above-described embodiment, a fixed guide that is fixed to the rod is shown, but it is possible to form a similar rib (thick portion) in the connecting portion of the floating guide as well.
