Description

  The present invention relates to a fishing line guide that is mounted on a fishing rod and guides a fishing line, and more particularly to a fishing line guide that has a feature in a frame portion that holds a guide ring through which the fishing line is inserted.

  2. Description of the Related Art Conventionally, the above-described fishing line guide includes a frame that is attached to the outer peripheral surface of a fishing rod and a guide ring that is fixed to the frame and into which a fishing line is actually inserted. For example, as described in Patent Document 1, the frame is generally formed integrally by pressing a metal plate material such as stainless steel or titanium, and the frame includes a fishing line. A ring holding portion for holding the guide ring through which the rod is inserted and a fixing portion for mounting on the outer surface of the fishing rod are integrally formed.

  Recently, for example, as shown in Patent Document 2, it has been proposed to use a fiber reinforced synthetic resin as a constituent material of a fishing line guide. This Patent Document 2 includes a ring holding portion for holding a guide ring, an attachment mounting portion (fixed portion) attached to a fishing rod, and a leg portion (support leg portion) positioned between the ring holding portion and the attachment mounting portion. Is integrally formed with a prepreg of a fiber reinforced synthetic resin.

  However, in the known technique disclosed in Patent Document 1 described above, since the frame is formed of a metal material, the weight is heavy, the performance such as specific strength, specific rigidity, and flexibility is poor, and the performance of the fishing rod is improved. Has become a bottleneck in achieving this. For example, in a fishing rod that is required to be lighter, if a large number of fishing line guides as described above are attached along the axial length direction, desired performance cannot be exhibited.

  Further, in the configuration disclosed in Patent Document 2 described above, although the fishing line guide can be reduced in weight, the arrangement of the reinforcing fibers constituting the fiber-reinforced synthetic resin material is not considered at all. Similar to the fishing line guide disclosed in Document 1, the performance such as specific strength, specific rigidity, and flexibility is not sufficient.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a fishing line guide that is light in weight and excellent in specific strength, specific rigidity, and flexibility.

  In order to achieve the above-described object, the present invention provides a ring holding portion for inserting a fishing line, a fixing portion fixed to a fishing rod, the ring holding portion and the fixing portion, and separating the fishing line from the surface of the fishing rod. A fishing line guide having a frame made of fiber reinforced synthetic resin, the supporting leg portion having an inclined portion extending from the ring holding portion toward the fixed portion, and the inclined shape. The part is characterized by arranging reinforcing fibers oriented in the tilt direction.

  The fishing line guide having the above-described structure can be reduced in weight because the frame constituting the fishing line guide is made of a fiber-reinforced synthetic resin material, and the fishing rod equipped with the fishing line guide having such a structure exhibits its original characteristics. It becomes easy to do. In addition, by providing an inclined portion extending from the ring holding portion through which the fishing line is inserted toward the fixed portion fixed to the fishing rod (fish), the fishing line is difficult to get entangled and easy to come off in the tip direction. Even if a load is applied due to entanglement or the like, since the reinforcing fibers oriented in the inclination direction are disposed, the flexibility at that portion is improved and the specific strength and specific rigidity are excellent.

  In the above-described configuration, the support leg portion is a portion that connects a portion through which the fishing line is inserted and a fixing portion that is fixed to the rod, and is a portion where a load from the fishing line acts greatly. The support leg part is also a part for separating the inserted fishing line from the surface of the rod, and corresponds to a portion inclined along the longitudinal direction (the direction in which the fishing rod extends and is the front-rear direction). The inclined portion may be formed as one or a pair in the width direction (left-right direction) when configured as a one-foot guide, and even when configured as a both-foot guide, On the other hand, one or a pair in the width direction (left-right direction) may be formed in the front-rear direction. Moreover, an opening and a notch part may be formed in the inclined part or the fixed part.

  In addition to the structure in which the ring holding part is formed separately from the frame made of fiber reinforced synthetic resin and the guide ring for inserting the fishing line is attached, the ring holding part itself is processed. This includes a configuration in which a fishing line can be inserted without attaching a separate guide ring.

  Further, the inclination direction of the inclined portion is defined by the direction in which the substantially center line in the inclined portion is directed, and the reinforcing fibers to be arranged are arranged so as to coincide with or substantially coincide with such an inclined direction. It only has to be done. In this case, the reinforcing fibers may be disposed within a range of ± 15 degrees, preferably within a range of ± 10 degrees with respect to the inclination direction, but at positions close to the ring holding part and the fixing part, Since it is necessary to adjust the shape and the strength of rigidity according to the portion, the direction of the reinforcing fiber may be changed by ± 15 degrees or more, for example, a range of ± 20 degrees may be used. Furthermore, when the angle at which the substantially center line and the axis of the eyelid intersect in the inclined portion is α, when the angle α is 30 ° or less, a range within 1/2 (for example, α is 30 °). In this case, the direction should be within 15 ° (see FIG. 2).

  Further, as described above, the reinforcing fiber oriented in the inclination direction is a case where a plurality of fiber-reinforced synthetic resin layers are laminated in the inclined portion, as long as there is a layer in which the reinforcing fibers are oriented in the inclination direction. In some of the plurality of layers, there may be a layer in which the reinforcing fibers are oriented in a direction other than the inclined direction. That is, if there is at least a portion (layer) in which the reinforcing fiber is oriented in the inclination direction, it is possible to improve the flexibility, specific strength, and specific rigidity described above.

  According to the present invention, a fishing line guide that is light in weight and excellent in specific strength, specific rigidity, and flexibility can be obtained.

  FIGS. 1 to 5 are views showing a first embodiment of a fishing line guide according to the present invention, FIG. 1 is a view showing a state where a fishing line guide is mounted on a tip rod, and FIG. 2 is a fishing line guide shown in FIG. 3 is a sectional view taken along line AA in FIG. 2, FIG. 4 is a sectional view taken along line BB in FIG. 2, and FIG. 5 is taken along line CC in FIG. FIG.

  The fishing line guide 1 of the present embodiment is configured as a so-called top guide that is attached to the tip of the tip of the fishing rod, and has a frame 2 made of fiber-reinforced synthetic resin.

  The frame 2 is formed in a ring shape and holds a guide ring 10, a fixing portion fixed to a rod R that is a fishing rod, and connects the ring holding portion 3 and the fixing portion. A support leg. In this case, the fixed portion corresponds to a portion fixed to the heel, for example, a portion fixed to the surface of the heel, or a portion fixed by inserting the heel. The fixing portion of the present embodiment is configured as a portion into which the flange R is inserted, and specifically, the first fixing portion divided in the front-rear direction by forming the opening 9 in the middle portion in the longitudinal direction. And a second fixing portion. That is, the fixing portion includes a first fixing portion 5A having a hole (竿 杆 fixing hole) 5a into which the tip of the heel R is inserted, and a hole (竿 杆 fixing hole) 5b through which the tip side of the heel R is inserted. It has the structure provided with the 2nd fixing | fixed part 5B which has.

  The ring holding portion 3 is disposed above the first fixing portion 5A (below in FIG. 2) and is a portion through which a fishing line is inserted (a fishing line insertion direction is indicated by an arrow X). As described above, the ring holding part 3 is formed in a substantially circular outer shape (annular) as a whole, and includes an opening 3a for fitting and fixing the guide ring 10 for guiding the fishing line. In this case, the guide ring 10 fitted and fixed in the opening 3a is formed in a ring shape, and a material having a small sliding resistance at the fishing line guide surface 10a portion which is the inner peripheral surface thereof, for example, titanium, aluminum, SUS, It is made of ceramics. The “ring holding portion” includes a configuration in which the fishing line is directly guided through the opening 3a without mounting the guide ring, in addition to mounting the guide ring 10 described above and guiding the fishing line.

  The fixing portions 5A and 5B and the ring-shaped ring holding portion 3 are connected by a supporting leg portion. Here, the “support leg part” corresponds to a part for separating the fishing line inserted through the ring holding part 3 from the surface of the rod, and in the configuration of the present embodiment, the first holding part 5A and the ring holding part are held. A first support leg 7 formed between the second support part 3 and the second support leg 8 formed between the second fixing part 5B and the ring holding part 3; That is, in the present embodiment, as described above, the opening 9 is formed along the longitudinal direction in the intermediate portion of the fixed portion, and correspondingly, the support leg portion is notched along the longitudinal direction. It is formed and has a structure having a plurality of support legs 7 and 8 in the axial direction. For this reason, in the region where the opening 9 is formed, the ridge R is exposed.

  The first support leg portion 7 is integrated with the ring holding portion 3 and extends in a direction orthogonal to the rod R (fishing line insertion direction X). Further, as shown in FIG. 1, the second support legs 8 are provided on both the left and right sides so as to be symmetric with respect to the heel R, and are respectively directed from the ring holding part 3 toward the second fixing part 5B. An extending inclined portion 8a is provided. That is, the “inclined portion” has a predetermined length in the fishing line insertion direction X, and extends from the ring holding portion side (the first holding leg portion supporting the ring holding portion or the ring holding portion) to the second fixing portion 5B. It becomes the part which extended toward.

  In the present embodiment, since the frame is formed by cutting out a tubular member made of fiber-reinforced synthetic resin as described later, the outer surface of the second support leg portion 8 (inclined portion 8a) is a figure. As shown in FIG. In addition, the second support leg portions (inclined portions) provided on the left and right sides are specified by the type of the fishing line guide, the position to be attached to the fishing rod, etc., and the height from the second fixing portion 5B and the fixing portion 5B The amount of swelling from the hole 5b to the left and right can be arbitrarily set.

  Reinforcing fibers are arranged in each inclined portion 8a so as to be oriented in the inclination direction. In this case, with respect to the inclination direction of the inclined portion, when viewed from the side as shown in FIG. 2, a line D that is substantially the center of the inclined portion (a line that is substantially the center in the intermediate region between the fixed portion and the ring holding portion). Defined as the direction of the center line D). Here, the “directing direction” will be described in detail. Since the inclined portion 8a is preferably configured so that it is difficult to get entangled even when a fishing line is caught and is easily removed in the tip direction, the ring holding portion 3 and the fixing portion 5B. It is necessary to adjust the shape adjustment and the strength of rigidity in accordance with these portions at a position close to, and the same inclination direction is not provided over the entire inclined portion. That is, as shown in FIG. 2, the surface of the region close to the second fixed portion 5B has a concave gentle slope 8d, and the surface of the region close to the ring holding portion 3 has a convex steep slope 8e. As a result, the inclination gradually becomes gentle and shifts to the top part 3c of the ring holding part 3, and the same inclination direction does not occur over the entire inclined part 8a.

  In the present invention, regarding the inclined portion 8a configured to be easily pulled out even if the fishing line is entangled, even if a load is applied due to entanglement of the fishing line or the like, the reinforcing fiber is disposed along the inclined direction, so that the flexibility at that portion is provided. The specific strength and the specific rigidity are improved. For this reason, it is preferable that the reinforcing fibers arranged in the inclined portion are arranged so as to coincide with or substantially coincide with such an inclination direction (direction in which the center line D is directed), Such an effect can be obtained if it is disposed within a range of ± 15 degrees, preferably within a range of ± 10 degrees with respect to the tilt direction. However, in the region close to the ring holding part 3 and the fixing part 5B, as described above, it is necessary to adjust the shape adjustment and the strength of rigidity in accordance with these parts. It may be changed by ± 15 degrees or more with respect to D.

  In the configuration of the present embodiment, the second support legs 8 are formed on the left and right sides so as to be symmetric with respect to the flange R, and the frame is a tubular member made of fiber-reinforced synthetic resin. Since it forms by cutting out, each inclined-shaped part 8a on either side is the state containing the reinforcing fiber of the direction which cross | intersects this in addition to the reinforcing fiber along an inclination direction so that it may mention later.

  Next, an example of a method for manufacturing the fishing line guide 1 configured as described above will be described with reference to FIGS.

  The frame 2 constituting the fishing line guide 1 is formed of a tubular member wound with a fiber reinforced prepreg (hereinafter referred to as a prepreg) in which a reinforcing fiber is impregnated with a synthetic resin. In this case, the areas of the fixing portions 5A and 5B of the fishing line guide and the area of the ring holding portion 3 are obtained by integrating two tubular members as shown in FIGS. Called a structure). That is, in such an integrated structure, the prepregs are wound around the cores having different diameters, and the prepregs are disposed adjacent to each other, and the prepregs are sequentially disposed on the two adjacent cores. After winding, it can be formed through a heating step and a decentering step. Note that the prepreg to be wound is a state in which the reinforcing fibers are aligned in one direction, or a sheet shape (woven fabric shape) in which the reinforcing fibers are knitted, a tape shape, and a thermosetting property. It is configured to impregnate a resin (for example, epoxy resin) or a thermoplastic resin (for example, nylon) as a matrix resin. As the reinforcing fibers, inorganic fibers such as carbon fibers and glass fibers, organic fibers such as aramid fibers and polyetherimide, and metal fibers such as SUS and titanium can be used.

  Specifically, the inner layer side of the fixing portions 5A and 5B described above is formed by winding a prepreg 20 in which reinforcing fibers are aligned in the circumferential direction around a thin core metal M1, and the ring holding portion 3 The inner layer side is formed by winding a prepreg 21 in which reinforcing fibers are woven into a core metal M2 having a diameter larger than that of the core metal M1. Then, as described above, the core bars M1 and M2 around which the prepregs 20 and 21 are wound are arranged adjacent to each other so that the prepregs come into contact with each other as shown in FIG. By sequentially winding the prepregs 24, 25, 26, and 27 around the cores of the gold M1 and M2, the outer layer side of the ring holding part 3, the outer layer side of the fixing parts 5A and 5B, and the support leg part 7, 8 are formed.

  In this case, the prepreg wound around the adjacent cored bars M1 and M2 is a prepreg 24 in which the innermost layer is a prepreg 24 in which reinforcing fibers are aligned in the circumferential direction, and the prepreg serving as a layer above the prepreg. No. 25 is one in which reinforcing fibers are aligned in the tilt direction. Further, the prepreg 26 that is the upper layer is one in which reinforcing fibers are aligned in the inclined direction intersecting the prepreg 25, and the prepreg 27 that is the outermost layer is a woven fabric-like reinforcing fiber.

  In addition, before winding the prepregs 24-27 with respect to the core bars M1 and M2 in the state of being adjacently arranged, the filling member along the longitudinal direction is formed in a hollow region existing between the core bars M1 and M2. It is preferable to arrange 22. The filling member is composed of a fiber bundle impregnated with a synthetic resin (fiber reinforced synthetic resin), a synthetic resin, a lightweight material (specific gravity is 2.0 or less), and the like. Thus, as shown in FIGS. 3 and 5, the gap between the fixed portion and the ring holding portion is filled, and the strength of the fixed portion can be improved.

  As described above, the metal cores M1 and M2 are disposed adjacent to each other, filled with the filling member 22 in the depressions of the two, and then wound with the prepregs 24 to 27 in order. In this state, the two tubular members are integrated (integrated structure) through a heating step and a decentering step.

  The frame 2 of the fishing line guide 1 is formed by cutting out a predetermined position with respect to the formed integrated structure (in practice, the integrated structure is long in the axial direction, so a plurality of frames are formed. Is possible). In this case, since the above-described core metal M1 becomes holes 5a and 5b of the fixing portion into which the collar R is finally inserted after being decentered, the outer diameter substantially coincides with the outer diameter of the collar R. What you have is used. Moreover, since the above-described cored bar M2 becomes the opening 3a to which the guide ring 10 is finally attached after being decentered, the one having an outer diameter substantially coincident with the outer diameter of the guide ring 10 to be mounted is used. It is done.

Hereinafter, a method for cutting out the frame 2 from the integrated structure will be specifically described.
First, the integrated structure is cut out in a direction crossing the axial length direction (direction intersecting). Therefore, the fiber-reinforced synthetic resin layer made of the prepreg laminated as described above is directly laminated in the radial direction. Next, it cut out from the tubular body part formed by decentering the core metal M1 so that the opening 9 shown in FIG. 2 was formed, and formed by decentering the core metal M2. Cutting is performed from the tubular body portion so that the inclined portion 8a of the second support leg portion 8 is formed.

  Thus, by cutting out, as shown in FIG.3 and FIG.5, the inner side of the 1st fixing | fixed part 5A and the 2nd fixing | fixed part 5B is formed with the above-mentioned prepreg 20. FIG. Further, the inner layer side of the ring holding portion 3 is formed by the prepreg 21 described above. That is, the fixing part and the ring holding part are independent layers, and the inner layer side of the ring holding part is a prepreg 21 in which reinforcing fibers are arranged in a woven shape as shown in FIG. Further, the inner layer side of the fixing portions 5A and 5B is the one in which the reinforcing fibers are aligned in the circumferential direction (prepreg 20) as shown in FIG.

  Furthermore, the outer layer side of the fixing parts 5A and 5B, the outer layer side of the ring holding part 3, and the support leg part 7 are all formed of the same fiber-reinforced synthetic resin layer, and the reinforcing fibers are aligned in the circumferential direction in order from the inside. Layer (prepreg 24), layer (prepreg 25) in which reinforcing fibers are aligned in the inclined direction, layer (prepreg 26) in which reinforcing fibers are aligned in the inclined direction intersecting the reinforcing fibers of the layer formed by prepreg 25, and reinforcing fibers. A woven fabric layer (prepreg 27) is formed.

  In addition, the filling member 22 is in a state where the center side region of the support leg portion 7 and the inner layer and the outer layer of the fixing portion 5B are arranged.

  The support leg portion 8 (inclined portion 8a) is a layer in which reinforcing fibers are aligned in the circumferential direction (prepreg 24) and a layer in which reinforcing fibers are aligned in the inclined direction in order from the inner side, as in the configuration on the outer layer side described above. (Prepreg 25), a layer (prepreg 26) in which reinforcing fibers are aligned in an inclined direction intersecting the reinforcing fibers of the layer formed by the prepreg 25, and a layer (prepreg 27) in which the reinforcing fibers are woven.

  As described above, the reinforcing fibers arranged in the inclined portion 8a are coincident with such an inclination direction (direction in which the center line D is directed) or substantially coincide with each other, or ± The reinforcing fibers arranged in the range of 15 degrees, preferably in the range of ± 10 degrees, are oriented by such prepregs 25 and 26. That is, in each of the inclined portions 8a provided on the left and right sides, one of the prepregs 25 and 26 is in a state where one prepreg is along the inclination direction, and the other prepreg is against the reinforcing fiber along the inclination direction Will be oriented in the crossing direction. Therefore, with regard to the prepregs 25 and 26 to be wound, when the frame is finally cut out from the integrated structure, the direction in which the reinforcing fibers are aligned is determined in consideration of the cutting direction (the direction of the inclined portion). What is necessary is just to select the direction. Further, since the inclined portion is formed by using the cored bar as described above, the reinforcing fibers can be arranged in the inclined direction, further in the circumferential direction and the longitudinal direction along the cored bar shape (FIG. 3). In the inclined portion, the reinforcing fibers are not arranged in the radial direction), and the strength can be improved efficiently.

  As described above, the frame shape as shown in FIGS. 1 and 2 is integrally formed by cutting out a predetermined position with respect to the integrated structure. In this case, the wall thickness can be changed by changing the configuration of the prepreg to be wound or by partially stacking the reinforcing prepreg along the axial length direction according to the part of the frame 2 to be formed. It is. For example, it is possible to improve the strength of the fixed portion by laminating and building up the reinforcing prepreg along the axial direction along the region of the fixed portion. Alternatively, the separation distance L between the heel and the guide ring shown in FIG. 3 can be adjusted by the thickness of the prepregs 20 and 21 and the number of windings, and the prepreg 24 is also applied to the support legs 8 shown in FIG. Depending on the thickness of ~ 27, the number of windings, the cutting direction, etc., it can be further expanded outward.

  When cutting out the frame from the integrated structure, it is possible to cut out a plurality of frames 2 by adopting any method such as cutting by pressing, cutting by liquid (water jet, etc.) in addition to cutting by a cutting tool. Thus, a lightweight and high-strength fishing line guide (frame) can be efficiently manufactured.

  In this case, since the ring holding part 3 is formed by cutting in a direction crossing the longitudinal axis, the fiber-reinforced synthetic resin layer is laminated from the inner side to the outer side in the radial direction, As a result, the strength and stability of the ring holding portion can be efficiently improved, and the size and weight can be reduced. Moreover, since the inner layer side of the ring holding part 3 is composed of a woven prepreg, when the cross section is viewed, the surface layer part is exposed (protruded) in a state in which the reinforcing fibers meander, A part of the reinforcing fiber comes into contact with the outer peripheral surface of the guide ring 10 attached thereto, so that the guide ring 10 can be reliably and stably held.

  Next, the cut frame 2 is subjected to a surface treatment. For example, by performing barrel processing, surface burrs are removed, and finish polishing is performed to such an extent that surface gloss is obtained. Regarding the degree of this polishing, it is possible to arbitrarily adjust the polishing agent, the polishing time, etc. according to the size, shape, material characteristics, etc. of the fishing line guide 1. By performing such barrel processing or the like, the frame 2 can be polished without cutting the reinforcing fiber, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained. .

  In addition, when performing said grinding | polishing process, it is preferable to grind | polish so that a part of reinforcement fiber may be exposed to the surface of the flame | frame 2, and a matrix resin may remain partially. By doing so, it becomes possible to further improve the gloss of the polished surface.

  Next, a film is formed on the whole or a part of the frame 2 as necessary. For example, it is possible to perform coating to improve the appearance and protect the frame body, or to deposit metal or ceramics.

  And the guide ring 10 is attached to the opening 3a of the ring holding | maintenance part 3 of the flame | frame 2 formed as mentioned above. As an attachment method of the guide ring 10, any fixing method such as press-fitting, adhesion, curling, or the like can be adopted.

  According to the fishing line guide 1 configured as described above, the frame 2 is made of a fiber-reinforced synthetic resin material, so that the weight can be reduced and the fishing rod equipped with the fishing line guide having such a structure has the original characteristics. It becomes easy to demonstrate. In particular, in a portion such as a tip rod, the weight can be further reduced, so that a delicate hit can be easily detected, and the performance of the fishing rod can be further improved. Further, by providing the inclined portion 8a extending from the ring holding portion 3 through which the fishing line is inserted toward the fixing portion 5B fixed to the fishing rod (fish), the fishing line is difficult to be entangled and easily removed in the tip direction. Even if a load is applied due to entanglement of the fishing line, etc., since the reinforcing fibers oriented in the inclination direction are arranged, the flexibility at that portion is improved, and the structure is excellent in specific strength and specific rigidity. Become.

  In the present embodiment, since the inclined portions 8a are formed on both the left and right sides of the ridge, the strength of the frame can be improved, and each inclined portion is added to the reinforcing fibers oriented in the inclination direction. In order to include reinforcing fibers oriented in the direction intersecting with them (including reinforcing fibers oriented in the circumferential direction by the prepreg 24 and reinforcing fibers formed into a woven fabric by the prepreg 27), the front-rear direction, the rotational direction, the twist, etc. It becomes possible to strengthen in a balanced manner against complex loads, and it is possible to efficiently reduce the weight and size. The prepregs 25 and 26 in which the reinforcing fibers are aligned in the inclined direction are preferably set so as to be opposite to each other at the same angle with respect to the axial length direction in consideration of the strength balance.

  Further, when forming the frame 2, the fishing line guide 1 of the present embodiment cuts the opening 9 along the longitudinal direction in the middle portion of the fixed portion and the support leg portion corresponding to the opening 9 along the longitudinal direction. A shape having a plurality of support legs 7 and 8 is formed so as to be symmetrical with respect to the axial direction by forming a notch. For this reason, in the region where the opening 9 is formed, the ridge R is exposed, thereby reducing the weight while preventing the strength of the frame from being lowered and improving the flexibility of the ridge. It becomes possible.

  In addition, in the periphery of the hole region (portion where the fixing hole of the ridge is formed) in the fixing portion for fixing the ridge, the prepreg 20 and the prepregs 24 to 27 are formed. It is preferable to reduce the number of reinforcing fibers to be oriented (in this embodiment, some of the reinforcing fibers of the prepreg 27 are oriented in the axial length direction). That is, in the fixing part around the hole area, by reducing the reinforcing fibers oriented in the axial length direction, the fixing part can be prevented from becoming more rigid than necessary. Damage to the rod can be prevented, and the deflection balance of the fishing rod can be improved.

  The fixing portion may include a reinforcing fiber oriented in the axial length direction. In this case, the direction intersecting the axial length direction (circumferential direction, intersecting direction) is stronger than the reinforcing fiber oriented in the axial length direction. It is sufficient that the amount of reinforcing fibers (including direction) is large. Preferably, the amount of reinforcing fibers in the axial direction may be set to 1/3 or less of the total amount of reinforcing fibers in the fixed portion.

  Next, another embodiment of the fishing line guide according to the present invention will be described. In the embodiment described below, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

FIG. 6 is a longitudinal sectional view showing a second embodiment of the fishing line guide according to the present invention.
The fishing line guide 1 of the present embodiment is not limited to the tip of the tip rod, and can be arbitrarily set according to the mounting position of the fishing line guide, such as the length of the fixing portion and the size of the fixing hole, and can be set at any position of the rod. It can be used in the configuration. The frame 2 constituting the fishing line guide 1 includes a ring holding portion 3 and a fixing portion 5 fixed to the fishing rod, and the fixing portion 5 has a rod fixing hole 5d so that the rod is inserted and fixed. Is formed. Moreover, between the ring holding | maintenance part 3 and the fixing | fixed part 5, the 1st support leg part 17 and the 2nd support leg part 18 which connect both are formed.

  The first support leg portion 17 is integrated with the ring holding portion 3 and is higher than the first embodiment (fishing line) so that it does not come into contact with the surface of the rod when feeding or winding the fishing line. (High in the direction orthogonal to the insertion direction X). Similarly to the configuration shown in FIG. 2, the second support legs 18 are provided on both the left and right sides so as to be symmetric with respect to the collar, and extend from the ring holding part 3 toward the fixing part 5. An inclined portion 18a is provided (only one of the support legs is shown).

  Here, as for the reinforcing fiber disposed in the inclined portion 18a, as in the above-described embodiment, it coincides with the direction in which the center line D is directed (inclined direction) or ± 15 degrees with respect to the center line D. It is disposed within a range, preferably ± 10 degrees. In addition to the reinforcing fibers oriented in such an inclination direction, reinforcing fibers in a direction intersecting with the reinforcing fibers (including a circumferential direction, an axial length direction, and an inclination direction) may be disposed.

  An opening 19 is formed between the fixed portion 5 and the second support leg portion 18, and a hole 17 a communicating with the opening 19 is formed in the first support leg portion 17. In this case, the opening 19 penetrates in the left-right direction (direction perpendicular to the drawing), and the opening 19 is formed widely by forming a cut 5 b on the surface of the fixed portion 5. Thus, by forming the punched holes 17a and the openings 19 in the frame 2, the frame 2 can be reduced in weight.

It is possible to guide. In addition, the ring-shaped ring holding portion 3, the support leg portions 27 and 28, and the plate-like projecting pieces 5E and 5D serving as the fixing portions are obtained by, for example, cutting out a tubular body formed of a plurality of fiber-reinforced synthetic resin layers. Since it can be formed as it is, the fishing line guide as a whole can be reduced in weight, and a fishing line guide having a configuration excellent in specific strength, specific rigidity, and flexibility can be easily manufactured.

  In addition, about the some fiber reinforced synthetic resin layer (prepreg) which comprises a tubular body, even if load acts from various directions with respect to a flame | frame by directing a reinforced fiber to a different direction, those directions of The rigidity can be increased efficiently while reducing the weight. Also, the strength can be improved efficiently by having a plurality of fiber-reinforced synthetic resin layers.

FIG. 10 is a side view showing a fourth embodiment of the fishing line guide according to the present invention.
The fishing line guide according to the present embodiment is configured as a one-foot guide, and the frame 2 includes a ring holding portion 3 that is formed in an annular shape and holds the guide ring 10, and a fixing portion that is fixed to the surface of the fishing rod R by bobbin winding or the like. And. In this case, the fixing portion of the present embodiment is configured by a plate-like protruding piece 5 </ b> F extending rearward (original side) from the ring holding portion 3. Further, the frame 2 includes a support leg portion 38 that connects the plate-like protruding piece 5F and the ring holding portion 3.

  The support leg portion 38 is a portion that is connected to the ring holding portion 3 by bending the tip side of the plate-like protruding piece 5F, and includes the inclined portion 38a as in the above-described embodiment. In addition, the ring holding portion 3 is inclined at a predetermined angle (θ) from the direction perpendicular to the fishing line insertion direction X, and is configured to easily pull out the fishing line.

  As for the reinforcing fiber disposed in the inclined portion 38a, as in the above-described embodiment, it coincides with the direction (inclination direction) in which the center line D is directed, or is within a range of ± 15 degrees with respect to the center line D, preferably Are arranged within a range of ± 10 degrees. In addition to the reinforcing fibers oriented in such an inclination direction, reinforcing fibers in a direction intersecting with the reinforcing fibers (including a circumferential direction, an axial length direction, and an inclination direction) may be disposed.

  In addition, since the frame of the fishing line guide of the present embodiment can be formed with a mold by laminating a plurality of prepregs as described below, the reinforcing fibers are unidirectional ( By using the prepreg aligned in the fishing line insertion direction X), it is possible to easily match the reinforcing fibers in the inclined direction. Hereinafter, with reference to FIG. 13, an example of the manufacturing method which forms the frame of the fishing line guide of this embodiment is demonstrated.

  First, a plurality of prepregs constituting the frame 2 are cut into a predetermined shape, and are stacked so as to form a plurality of layers. The number of prepregs to be superimposed (number of layers) and the configuration of individual prepregs are not particularly limited, but the frame 2 is formed with a plurality of bent portions as shown in FIG. It is preferable to arrange a reinforcing layer that reinforces this portion.

  Among the prepregs laminated in plural, those having reinforcing fibers oriented in the direction of the arrow are used for at least a part thereof, and these prepregs are laminated and set in the mold 50. In this case, the mold 50 is constituted by an upper mold 51 and a lower mold 52 that are divided vertically (the divided position is indicated by reference numeral 50A), and the laminated prepreg is placed at a predetermined position of the lower mold 52. Set. Between the upper mold 51 and the lower mold 52, depending on the position where the laminated prepreg is set, the internal space, that is, the frame fixing portion (plate-shaped protruding piece) 5F, the support leg portion 38, and the ring holding portion A space 50a for forming 3 is formed, and a surface area is coated with a release agent. The space 50a has an inner surface corresponding to the thickness and surface shape of the frame 2 so that the frame 2 shown in FIG. 10 is formed when the upper mold 51 and the lower mold 52 are pressed. For example, when the laminated prepreg is set on the lower mold 52, a bent forming convex portion 52a is formed at a position corresponding to a bent portion (a bent portion formed between the fixed portion and the support leg portion), The upper mold 51 is formed with a bend forming recess 51a corresponding to the bend forming protrusion 52a.

  Note that the prepregs to be laminated may be set in the lower mold in a state where the whole is overlapped at once, or may be laminated in a plurality of times, for example, by setting one sheet at a time. By dividing into a plurality of times as described above, the movement of the reinforcing fibers can be reduced and the lower mold 52 can be accurately set at a predetermined position. Further, the mold is merely an example, and the mold splitting direction can be set to any form such as a horizontal direction or an inclined direction. Further, the guide ring may be previously positioned with respect to the ring holding portion, and the frame on which the guide ring is mounted may be simultaneously formed.

Then, as described above, after setting a plurality of prepregs in the lower mold 52, the mold is clamped with the upper and lower molds, and the matrix resin is cured by pressurization and heating, and then the molded product is removed from the mold 50. Take out.
Next, the frame is cut out from the molded product so as to have a predetermined shape. As described above, since the prepreg is a plate-like body in which a bent portion is formed after the heat-curing treatment, it is cut out by pressing, cut out with a liquid (water jet, etc.), cut out with a cutting tool (end mill, etc.), etc. By adopting an arbitrary method, it is possible to cut out a plurality of frames 2 from one molded product, and it is possible to efficiently manufacture a lightweight and high-strength fishing line guide.

  Next, detailed processing is performed as necessary. This detailed processing is performed by, for example, removing the burr of the frame or forming the shape of the plate-like protruding piece 5F into a curved shape so that it can be easily placed on a fishing rod, or by fixing the end of the fixed portion so that it can be easily wound and fastened. It corresponds to polishing.

  Next, a surface treatment of the frame is performed. For example, surface treatment is performed to such an extent that surface polishing (barrel polishing or the like) or surface gloss is obtained as necessary. Regarding the degree of this polishing, it is possible to arbitrarily adjust the polishing agent, polishing time, etc. depending on the size, shape, material characteristics, etc. of the fishing line guide. By performing such a surface treatment, the frame can be polished without cutting the reinforcing fiber, the strength can be stabilized, and a fishing line guide having an excellent appearance can be obtained. In addition, when performing such a polishing process, it is preferable to polish so that a part of the reinforcing fibers are exposed on the surface of the frame and a part of the matrix resin remains. By doing so, it becomes possible to further improve the gloss of the polished surface. Moreover, you may form a film in the whole or one part of a flame | frame as needed. For example, coating may be performed to improve the appearance or protect the frame body, or metal or ceramics may be deposited.

  Then, a guide ring is attached to the opening of the ring holding portion of the frame formed as described above. In addition, as above-mentioned, attachment of a guide ring may be carried out simultaneously with a flame | frame, may be performed after surface treatment, and can be performed at the time of the arbitrary processes in the meantime.

As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously.
In the present invention, the frame portion constituting the fishing line guide 1 is made of fiber reinforced synthetic resin, and a supporting leg portion having an inclined portion is formed on such a frame portion, and the fiber reinforced synthetic material arranged on the inclined portion. It is characterized in that the direction of the resin is directed in the tilt direction. For this reason, the method for forming the frame is not limited to the manufacturing method as described above, and various methods can be used. For example, in the case of molding with a mold, a long fiber and a synthetic resin are injected into the mold at the same time, or reinforcing fibers are arranged in the mold first and then the synthetic resin is injected later. May be. In addition, a reinforcing fiber bundle impregnated with a synthetic resin (a fiber bundle made into a thread or a net or braid) is installed in a groove formed in a mold. It may be a configuration. Further, when the reinforcing fiber and the synthetic resin are simultaneously injected into the mold, it is preferable to use a long fiber having a length of 3 to 15 mm.

  In addition, the type and elastic modulus of the reinforcing fiber in the fiber-reinforced synthetic resin material, the configuration such as the resin impregnation amount, the thickness, and the lamination state are not limited to the above-described embodiment, and may be variously modified. Is possible.

  Further, the fishing line guide can be applied to various types of fishing line insertion, for example, a fixed guide, a floating guide, an introduction guide in a through-type fishing rod, etc. There are no particular limitations on the configuration, such as a configuration in which a plurality exists as in the embodiment or a single configuration in the fourth embodiment.
