However, in the coupling structure disclosed in Patent Literature 1, when the movement guide is attached to the fishing rod and is intended to be arranged in a straight line with the top guide, even if a target as disclosed in Patent Literature 3 is provided, the alignment structure is always arranged in a straight line. Therefore, in throwing of a fishing rod, the smooth throwing which minimized the resistance of feeding of a fishing line cannot be performed. That is, the angular position provided in the inner periphery of the mounting cylinder of the movement guide is not necessarily determined by the angle position with respect to the centerline of each movement guide, and can fluctuate within the range of 1 pitch of unevenness | corrugation. In addition, even when the angle position with respect to the center line of each movement guide is fixed, even if it is constant, the angle position relationship between the said uneven angle position and the non-circular cross-sectional shape of the rod attachment sheet is not necessarily determined, and therefore it is necessarily lined up in a straight line with high precision. I cannot say that.

Moreover, in the aspect disclosed by patent document 2, since the pitch of the padding part side unevenness | corrugation and the pitch of the mounting cylinder side unevenness | corrugation are different, only a part of the unevenness | corrugation tank is bite, and there exists a possibility that a convex part may be missing when the movement guide receives a large force which tries to rotate. have. Alternatively, the fishing rod is more rigid and more difficult to bend as it is rearward. Therefore, the guide guide seat equipped with the movement guide is intended to rotate relative to the fishing rod via the fishing line, so that the greater the shear force (grabbing force) is applied to the support sheet in the rear position, which causes a problem in durability.

The fishing rod itself often causes some bending due to heat molding, and the processing accuracy of the padding portion based on the fishing rod portion decreases. Moreover, although a padding part is normally formed with a prepreg, knitting generally occurs by winding up a prepreg. Even if this surface is ground ungrinded and finished in circular cross section, the shaft center does not coincide with the shaft center of a fishing rod in many cases. Therefore, in the case of the grinding process in which a plurality of irregularities are formed in the padding part, in the grinding process of the padding part based on the fishing rod, the grinding is performed by measuring the padding part surface position one by one before grinding it for each grinding of each groove. Otherwise, the groove depth cannot be made constant. In reality, however, the manufacturing efficiency is very poor in the case of doing this for each groove. However, in the first one-time measurement, when the fishing rod is held and the fishing rod is pitch-rotated for each groove, as described above, the padding portion cannot be concentric with the stage, causing fluctuations in the groove depth. Since the fishing rod is to be as lightweight as possible and does not want to impair the warpness, there is a basic requirement to form the padding portion as thin as possible. Therefore, if the depth of the groove is uneven with respect to the padding portion to be thinned, the groove may not be ground depending on the place, or on the contrary, the fishing rod itself may be ground too deep. This damages the strength of the fishing rod. To prevent this, the padding portion must be thick enough.

In the case of the said patent document 4, since only one or two planar parts are formed, grinding depth etc. for forming in a planar part may be measured and performed every time grinding. However, as the formation of a large number of recesses and grooves (grooves) disclosed in Patent Document 5 by grinding, processing while measuring the standard for each groove one by one requires labor and becomes a costly fishing rod.

Therefore, the present invention, in the case of a fishing rod that installs the guide support sheet in a plurality of longitudinal direction portion of the end stand, the movement guide is arranged in a straight line with high precision with respect to the top guide, and at the same time prevents the irregularities of the rear support sheet to improve the durability To provide fishing rod which let you do it.

Furthermore, an object of the present invention is to provide a fishing rod guide that can be reliably prevented from being attached to the guide support sheet and that is light in weight and has good bending property.

In addition, in the case of forming a guide support sheet by processing a large number of irregularities in the padding portion of the fishing rod, the depth of the groove can be made constant, and the object of the present invention is to provide a low cost manufacturing method.

In view of the above object, in claim 1 of the present invention, a guide support sheet is integrated outside a predetermined position of a fishing rod made of fiber-reinforced synthetic resin, stretched in the longitudinal direction of the fishing rod on the outer circumference of the guide support sheet, and provided in a plurality of circumferential directions. The groove portion of the fishing line guide having a sheet-side concave-convex groove and having a groove depth from the top of the concave-convex groove to the valley portion is generally constant in the circumferential direction of the guide support sheet, and is also substantially constant in a predetermined length in the longitudinal direction. An inner circumference provides a fishing rod characterized by having a tube side uneven jaw having a pitch equal to that of the base sheet side uneven jaw.

Usually, constant means that the fluctuation of most grooves is within ± 0.05 mm. Preferably it refers to the variation within ± 0.03 mm.

Since the groove depth is generally constant in the circumferential direction of the guide support sheet, the thickness of the guide support sheet can be set to be thin enough to leave a predetermined amount of thickness at the constant depth, contributing to the weight reduction of the fishing rod and the prevention of the suppression of the warpage. Moreover, since it is also substantially constant also in the predetermined length of the longitudinal direction, when the mounting cylinder part of a fishing line guide is inserted, a predetermined amount of bite engagement feelings fully generate | occur | produce, and it can reliably prevent rotationally attaching to a predetermined position of a guide support sheet. In addition, since the inner periphery of the mounting tube portion of the fishing line guide is an uneven group of the same pitch as the pitch of the supporting sheet side uneven group, all convex and concave groups of the fishing line guide are combined with each other, so that an equal load acts, thereby improving durability.

The fishing rod of Claim 1 is provided with the height of the groove bottom surface of the said support seat side uneven | corrugated tank gradually increasing in the back side.

Since the height of the groove bottom surface of the base sheet side unevenness | corrugation groove becomes gradually high in the back side, it can be firmly joined by pressing the mounting cylinder part of a fishing line guide to the back side.

The fishing rod according to claim 3 provides the fishing rod according to claim 1, wherein the supporting sheet side unevenness is terminated at the rear portion in the guide supporting sheet region.

The fishing line guide press-fitted to the guide support sheet can be prevented from being inadvertently drawn out to the rear side due to wear of the support sheet side unevenness or the tube side unevenness.

The fishing rod according to any one of claims 1 to 3, wherein the groove depth of the base sheet side unevenness is shallower than the groove depth of the tube side unevenness.

Since the groove of the support sheet side unevenness | corrugation groove is set so that it may differ from that of the cylinder part side (shallow), a gap will arise between the mounting cylinder part of a fishing line guide, and a guide support sheet at the time of engagement. Therefore, the increase of the bending rigidity of the guide base sheet of the site | part in which the guide was mounted is alleviated. In addition, since the side of the base sheet side unevenness is made shallower, the thickness of the guide base sheet can be set thin, which can contribute to the reduction of the bending rigidity increase and the weight reduction.

In Claim 5, the guide support sheet is integrated outside the predetermined position of the fishing rod made of fiber reinforced synthetic resin, The process of processing the said guide support sheet outer periphery to the circular shape of a predetermined precision, and the said circular guide support sheet outer periphery on the basis of The manufacturing method of the fishing rod characterized by having the process of processing the groove | channel extending | stretched in a longitudinal direction to a guide base sheet, and the depth of the some groove | channel of the said predetermined pitch is generally constant in the circumferential direction.

The predetermined precision means the minimum length (radius) from the center of the minimum circumscribed circle (radius R1) circumscribed to the processed guide support sheet outer periphery to R2, and R1-R2 = Δ is 0.05 mm. Hereinafter, Preferably it means 0.03 mm or less.

The processing of the grooves extending in the longitudinal direction on the guide support sheet based on the outer circumference of the circular guide support sheet means that the guide support sheet is fixed by the chuck or the guide support sheet is supported by the support hole during the groove processing. In the former, the axial center of the guide support sheet can always be captured at the same position since the spatial position of the central axis of the chuck and the guide bearing sheet coincide (that is, the position of the central axis of the chuck is always captured (typically in a constant position). (Typically in a constant position)], while the latter aims at always capturing (typically in a constant position) the center of gravity of the guide support sheet calculated from the support surface of the support. .

Since the circular outer periphery of predetermined precision becomes a reference | standard even when rotating the guide support sheet processed to circular cross section, the axial center of a guide support sheet can be kept unchanged. Therefore, the outer circumference of the guide support sheet of the object to which the groove | channel should be processed can always be maintained in the unchanged position regardless of rotation. That is, for example, the spatial position such as the height of the guide circumferential sheet outer circumferential surface determined by measurement or the like before grooving can always be kept constant along the rotation. Therefore, a plurality of grooves having a constant depth in the circumferential direction of the guide support sheet can be kept intact in the circumferential direction of the guide support sheet when the depth cut in from the guide support sheet outer circumferential surface at the time of the first groove processing can be maintained without repeating measurement or the like even after rotating thereafter. Can be easily formed.

In the sixth aspect of the present invention, the guide support sheet is provided at a plurality of longitudinal direction portions of the outer end of the fiber-reinforced resin end-to-end of the type having a pointed guide and a pointed tip, and is oriented in the longitudinal direction of the end of each guide support sheet outer periphery. The angular position and the pitch angle of the concave-convex are respectively provided with a plurality of concave-convex grooves of a constant pitch angle and are concave-joins of each support sheet, the concave concave closest to a plane including a top guide center and an end-to-center axis. Each support sheet is the same, and the inner periphery of the mounting cylinder of the movement guide attached to each guide support sheet is provided with the unevenness | corrugation of fixed pitch angle, and the unevenness | corrugation number of the said cylinder side is the integer containing the same thing as the unevenness number of the said support sheet side Double side, convex on the cylinder side, in the plane including the guide ring center and the cylinder center axis of each moving guide Chapter angular position with irregular sets of pitch angle to the nearest pair of the convex plane provides a fishing rod, characterized in that the same each other, each moving guide. The predetermined concave and convex may be replaced with a predetermined convex and concave.

Since the pitch angles of the unevenness are the same between each support sheet, the number of the unevenness of each support sheet is the same, and the constant pitch angle and the end points are sharp, so the circumferential distance between the recesses (or convexities) The back seat in the rear position is larger. Therefore, the greater the rearward shear force received from the moving guide, the more irregular the grooves in the wide distance interval, so the durability is improved. Alternatively, since the above-described angle positions of the predetermined recesses are the same between the base sheets, considering that they are a constant pitch angle, the recesses or convex columns are positioned at the same angle positions of the end to the outer periphery of each base sheet. In accordance with this, since the angular positions of the above-described predetermined protrusions on the cylinder side are the same for each of the movement guides, when the movement guides are attached to the guide support sheet so that the protrusions face the recesses, they are aligned linearly with accuracy with respect to the top guide. In addition, since the unevenness | corrugation number of a cylinder side is an integer multiple containing the same thing as the unevenness | corrugation number of a support sheet side, the total convex tank of a support sheet side can be attached to the recessed groove of a cylinder side.

In Claim 7, the groove depth from the top part to the valley part of the said support seat side unevenness | corrugation is substantially constant in the circumferential direction, and provides the fishing rod of Claim 6 which is usually constant in the predetermined length of the longitudinal direction.

The fishing rod according to claim 8 provides the fishing rod according to claim 6 or 7, wherein the passing side unevenness is the same as the support sheet side unevenness.

In this case, the convex and concave grooves of each other are all joined to each other at the time of mounting coupling, so that an equal load acts, thereby improving the durability of the concave-convex tank.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail based on embodiment shown in an accompanying drawing.

1 is a side view of an end region of a fishing rod according to the present invention. In this example, loose-fitting fishing line guides 10A, 10B, and 10C in the end band 10 made of fiber-reinforced synthetic resin reinforced with synthetic fibers such as epoxy resin and reinforced with reinforcing fibers such as carbon fibers. ) Is held in a batch. Guide support sheets ZA, ZB, and ZC are provided in the vicinity of the three places of the end table 10. Moreover, the top guide 10T is attached to the front-end | tip part. Reference numeral 12 is a fishing rod handle. The fishing rod of this example has three connecting bodies, and there are also foundation rods which are not shown in figure.

Although mentioned later, each guide support sheet is integrally formed on the surface of the end stand 10 which is a fishing rod main body by winding, such as fiber reinforced resin prepreg, with the end stand shaping | prepreg at the time of shaping | molding of a stand. You may integrate after shaping | molding of the end stand. After shaping | molding, it finishes in circular cross section, and the uneven | corrugated tank J extended | stretched in the longitudinal direction on the surface of the guide base sheet is provided in large numbers by the predetermined pitch in the circumferential direction. In the present example, however, the vicinity of the rear end of each guide receiving sheet is a tubular portion E in which a concave-convex groove is absent and a circular surface remains.

The loose fishing line guides 10A, 10B, and 10C have a mounting cylinder portion T for attaching to each of the guide support sheets, a guide ring G for guiding the fishing line, and the guide ring as shown in FIG. It has the frame part F which connects the said mounting cylinder part. The guide ring G is made of a wear resistant material made of ceramics such as silicon carbide and metal such as stainless steel. The mounting cylinder part T can be formed from a synthetic resin or a metal. In addition, the frame part F can be formed with a metal or synthetic resin.

Although the longitudinal cross section is shown in FIG. 2 as an example by the guide support sheet ZB of an intermediate position, the other two guide support sheets are also the same. In this example, the uneven | corrugated tank J is provided over the whole periphery except the cylindrical part E of the vicinity of the rear end part of the guide support sheet ZB. FIG. 3 shows an enlarged partial cross section taken along arrow line C-C in FIG. As for the uneven | corrugated tank J, the convex tank J1 and the concave tank J2 are extended in the longitudinal direction. In this application, a recess may be called a groove | channel. The width of the convex surface leaving the surface ZBS ground in a circular shape is a, the width of the groove is b, and a + b is one pitch P, in this example, the same pitch over the entire circumference. Asperities are formed.

The depth f of the groove is usually constant in the front side most region L1 of the unevenness. However, the bottom thickness t of the deepest part of the groove is t1 at the front end of the region L1, t2 (> t1) at the rear end, and gradually thicker, i.e., unevenness from the front end to the rear end. The height of the groove bottom surface of a bath is gradually formed high in the back side. That is, when the outer periphery of the guide support sheet was ground and formed on the circular surface ZBS, it was set as the guide support sheet of the tapered tip. In the short region L2 on the rear end side of the irregularities, the groove depth gradually becomes shallow to the rear side, and eventually reaches the surface of the cylindrical portion E. As shown in FIG.

Since the groove depth f is generally constant in the length L1 of the longitudinal direction, a predetermined amount of bite engagement is sufficiently generated when the mounting cylinder portion of the loose fishing line guide is inserted, so that it is secured at a predetermined position of the guide support sheet. Anti-rotation can be installed. Moreover, since the height of the bottom surface of the groove of the unevenness is gradually increasing at the rear side, it can be firmly engaged by press-fitting the mounting tube portion of the fishing line guide to the rear side. In addition, since the uneven line is terminated at the rear part in the guide support sheet area (the cylindrical portion E remains), the loose fishing line guide press-fitted to the guide support sheet causes the wear of the uneven support on the support sheet side or the uneven surface of the tube portion. By this, it can be prevented from being inadvertently drawn out to the rear side.

Further, the thickness t1, t2 of the groove bottom of the guide support sheet is preferable because it can be made lighter than the thickness T1, T2 of the tip 10 at the position corresponding thereto. In addition, the thickness t of the groove bottom of the area L1 between these is thinner than the tip-to-thickness T of the position. The constant groove depth f is for example 0.1 mm. The depth f is a groove as shallow as 0.02 to 0.2 mm. Therefore, the guide support sheet can be made thin, and in the present example, the thickness t + f of the guide support sheet may be 0.2 to 0.4 mm or 0.2 to 0.5 mm, and the thickness (T1 + T2) of the end table 10 may be used. It forms in about 30 to 80% with respect to / 2. In this way, inhibition of warpage is prevented. Moreover, it contributes to weight reduction of a fishing rod.

In the front end part and the rear end part of a guide base sheet, you may form inclination type | mold step relaxation parts DS1 and DS2 which gradually reduce to the front and rear, respectively. You may form this with synthetic resin or a coating material. In addition to the relaxation of the stress concentration when the tip is bent, this step relaxation portion also exhibits the effect of improving the appearance.

On the inner circumference of the mounting tubular portion T of each loose fishing line guide, an uneven group J 'having the same pitch as that of the uneven group J provided on each corresponding guide support sheet is formed. Therefore, at the time of joining, all the convex and concave jaws are combined with each other, so that an equal load acts, thereby improving durability of each. Fig. 5 shows the state in which these are combined with each other. 6 shows an enlarged view of a part thereof.

The groove depth f of the support sheet side uneven groove J is larger than the depth f '(the height of the convex groove J1') of the groove J2 'of the tube side uneven groove J' of the loose fishing line guide. Shallow. In addition, the tip-angle-angle (theta) of the mountain-shaped convex-shaped J1 'of the tube part uneven | corrugated tank J' exists in the range of 60 degree | times-120 degree | times, and it is about 90 degree here here.

On the other hand, the shape of the groove J2 of the base sheet side unevenness is wide and shallow, and in this example, it is a curved shape like a part of circular or ellipse shape. Since the groove J2 is shallow and wide, as shown in Fig. 6, the convex jaw J1 'which is a mountain shape of the tube-side concave-convex jaw J' comes into contact with the bottom of the groove J2, and the convex jaw J1 is formed. A relatively large gap SP1 and SP2 remains between the convex jaws J1 of the supporting sheet-side uneven jaw in the left and right sides of the '). Further, a slightly larger gap SP3 is also formed between the top surface of the convex jaw J1 of the supporting sheet side uneven jaw J and the groove J2 'of the tube side uneven jaw J'. Therefore, although the convex tank J1 'of the tube part uneven | corrugated tank J' touches the bottom part of the low position of the groove | channel J2 of the base sheet side uneven | corrugated tank J, the edge part of right and left of the convex tank J1 It is prevented from abrasion and the durability of the uneven tank J having a shallow groove is improved.

When the groove depth of the concave-convex jaw is shallow as described above, or when the thickness of the guide support sheet is thick, the convex jaw is easy to be missed, so that the constitution of the concave-convex jaw can be improved by improving durability.

That is, the guide support sheet is integrated outside the predetermined position of the fishing rod made of fiber-reinforced synthetic resin, extends in the longitudinal direction of the fishing rod on the outer circumference of the guide support sheet, and has a plurality of the support sheet side concave-convex grooves formed at a predetermined pitch in the circumferential direction. The grooves of the concave-convex grooves have a shape where the groove depth from the top of the concave-convex grooves to the valleys is shallow, and the groove width is wide. And the groove depth of the tube-side uneven jaw is at least twice the depth of the groove of the base sheet side uneven jaw, or the convex jaw usually forms a mountain shape, and its tip angle is in the range of 60 to 120 degrees. do.

According to this, the grooves of the supporting sheet side unevenness are shallow and wide, and the groove depth of the tube side unevenness having the same pitch is not less than twice the depth of the grooves of the supporting sheet side unevenness, and the convex roughly forms a mountain shape, Since it is within the range of 60 to 120 degrees, in the combined state, the tube-side convex top of the tube-side convex groove contacts the bottom of the groove of the support sheet-side concave-convex groove, and the acid-side portion of the tube-side convex groove is the edge of the groove of the support sheet-side groove, that is, the support sheet. It is possible to prevent contact with the corner portions of the side convexities. Therefore, it is possible to protect these edge portions which are easily distorted or worn and damaged, and the shallow grooves can be kept long, thereby improving durability. In addition, since the grooves are shallow, the thickness of the guide support sheet can be set thin, which can contribute to the reduction of the bending rigidity increase and the weight reduction.

In addition, each loose fishing line guide can be removed forward from the corresponding guide support sheet, and the loose fishing line guide at the rear is comprised in each dimension form which can also pass the guide support sheet in front. In addition, the maximum outer diameter of each guide support sheet is formed smaller than the inner diameter of the front end of the rod handle 12. Therefore, the end stand 10 can be received in a vibrating extraction type with respect to the rod handle tip 12.

Fig. 7 shows another embodiment of the guide support sheet, and Fig. 8 is an enlarged cross sectional view along the arrow indicator line H-H. It is an example that the uneven | corrugated tank J may be provided in the range (theta) of about 120 to 270 degree which is a part rather than the whole periphery of the guide base sheet ZB '. Thus, a circular surface remains outside this angle range.

Fig. 9 shows a guide bearing sheet ZB before grinding the unevenness of steel, and shows a state in which the surface ZBS of the guide bearing portion ZB is processed into a highly precise circle. In the case where the cylindrical padding portion is formed by winding a fiber-reinforced resin prepreg sheet or the like on an end position 10 or a rod material for molding the prepreg sheet, the prepreg sheet or the like has a winding start end and a winding end portion. In view of this, a so-called knitting part is often produced, and even though the heat molding is performed, the outer periphery of the cylindrical padding part is generally not a high-precision circular shape, and requires a grinding process.

In addition, since the end band itself is also likely to be bent due to a large amount of bending due to heat forming, the end pad 10 is fixed and rotated by a tool or the like in a process of grinding the surface of the cylindrical padding part with high precision. In this case, it is difficult to keep the shaft center constant, and is usually performed by centerless machining. In this way, the shaft center CL2 of the guide base sheet ZB which has the surface ZBS processed with the precision precision circularly does not correspond with the shaft center CL1 of the edge 10 of the position. However, the surface ZBS of the guide support sheet is formed in a circular shape with high precision.

Instead of the tireless machining, the surface of the cylindrical padding portion may be ground by holding the portion within 30 mm from the end of the cylindrical padding portion of the end stage 10 by a chuck of a machine tool or the like and rotating the end stage 10. In this case, since the site | part immediately adjacent to a cylindrical padding part is hold | maintained, the vibration of the cylindrical padding part used as grinding object hardly generate | occur | produces, and the shaft center CL1 and the shaft center CL2 mostly coincide. Therefore, the thickness of the cylindrical guide support sheet can be made uniform in the circumferential direction, and can be made to the minimum thickness necessary for forming the uneven line than in the case of uncentering, contributing to the weight reduction of the fishing rod.

Fig. 10 shows a plurality of irregularities J extending in the longitudinal direction of the end table 10 in a circumferential direction, on the surface ZBS of the guide bearing sheet processed in a circular shape with high precision in Fig. 9 at a predetermined pitch. The process which shows is roughly shown. When grinding the groove of the uneven steel J, the cylindrical portion E near the rear end of the guide support sheet surface ZBS is held by the chuck TK, and the end table 10 is held in the horizontal direction. In this case, while retaining and rotating the tool (Price) t1 shown in FIG. 11 in this holding | maintenance state, in this case, the groove which aimed at the longitudinal direction is ground to the upper surface side of a guide support sheet. In order to prevent the end 10 from being bent at the time of this processing, the support opening UK for receiving the lower surface side of the guide support sheet ZB may be provided. Next, in the state which hold | maintained the guide support sheet by the chuck | zipper TK, predetermined pitch rotation is carried out similarly and the adjacent groove is ground. This is repeated later. Thereby, the guide support sheet shown in FIG. 1 or FIG. 2 is formed.

Instead of rotating the chuck TK as described above, the holding of the chuck is loosened, and the tip 10 is rotated by a predetermined pitch angle by other means, and the same cylindrical portion E is held again in that state to hold the tool t1. ) May be grooved. After all, it is the cylindrical portion E which is a part of the outer circumferential surface ZBS of the guide support part, and is not the outer circumferential surface of the end table 10 itself. In this manner, a part of the outer circumferential surface ZBS of the guide support portion, which is ground in a highly accurate circular shape, is held, and a groove having a predetermined depth is machined on the outer circumferential surface ZBS with the tool t1.

In this processing method, even when the guide support sheet ZB, which is the object of the grooving process, is rotated (with the end stand), the outer peripheral surface ZBS of the guide support sheet is circular with high precision, so that the tool t1 initially set The cutting depth of is equal to the first cutting depth even if the tool after rotating at an arbitrary angle is applied as it is to each part of the outer circumferential surface that faces the guide support sheet without changing the measurement or the like again. That is, during groove processing, since the circular outer peripheral surface ZBS of the guide bearing sheet with high precision is always held, the depth of the groove | channel by the tool t1 can always be made constant regardless of a rotation angle. In this invention (claim 5) of the method which concerns on this invention, it describes on the basis of the circular guide support sheet outer periphery.

The tool t1 used in the above example is seen from the side in Fig. 11 (b), and the blade HA is mounted on the tip of the rotary shaft JK and the blade HA is fixed on the tip of the rotary shaft. ) Is fixed. (a) is a front view. The shape of the groove J2 is determined according to the shape of this blade HA.

Hereinafter, unlike the case of FIG. 10, the processing method at the time of installing the uneven | corrugated tank J in the whole outer peripheral surface of a guide base sheet is demonstrated. The chuck is required to hold the guide support sheet so as to be pinched from the top or the left and right, and to provide an opening so that the outer peripheral surface of the guide support sheet is exposed to the outside of the chuck. The cutting amount is set with respect to the outer circumferential surface of the guide support sheet exposed to the opening, and the blade of the tool is contacted to form a groove in the longitudinal direction over the entire length of the outer circumferential surface.

After the processing of one groove, it is rotated per chuck, or the chuck is loosened and rotated by a predetermined angle, and the other guide is processed by holding the guide support sheet with the chuck again, and then repeating this. Therefore, in the case of groove processing over the whole periphery, the processed uneven part may be hold | maintained. This processing apparatus can be used as a general price board. This method is also based on the outer circumference of the circular guide support sheet (in some cases, the convex surface of the concave and convex grooves remaining in the outer circumference of the circular guide support sheet), similarly to the method of forming the concave-convex groove described in FIG. It is easy to make constant.

12 is a view for explaining an example of a manufacturing method of the end table 10 provided with the guide support sheet shown in FIG. The end-to-main body prepreg sheet 22 is wound up to the core 20, and the prepreg sheet members 24A, 24B, 24C for guide support sheet formation are wound up in the suitable position on the outer side after that. Each sheet member may be laminated | stacked on the prepreg sheet 22 for main bodies beforehand, and you may wind up simultaneously. In addition, the kind, number of sheets, thickness, number of windings, material, etc. of each prepreg can be set arbitrarily.

After the prepreg sheet is wound up, the tension tightening tape is wound up in the usual manner and heated and calcined in this state. Thereafter, the tensioning tape and core are removed or removed to form an end. Thereafter, the outer circumferential surface of the guide base sheet is processed into a circle, and at the same time, an unevenness is formed.

Since the prepreg sheet member for guide receiving sheet formation does not want to inhibit the bending property of an end stand as much as possible, what is necessary is just to use the low elastic modulus carbon fiber whose elasticity modulus is 5000 kgf / kPa (49000 N / kPa) or less as a reinforcing fiber. For example, a unidirectional alignment sheet in which an epoxy resin is impregnated into a reinforcing fiber in which carbon fibers having an elastic modulus of 1000 kgf / kPa (9800 N / kPa) is aligned in one direction is used. The direction of the carbon fiber is in the longitudinal direction of the end band, and the increase in rigidity can be suppressed by using a prepreg using a reinforcing fiber having a low modulus of elasticity, and the strength and durability can be improved by the longitudinal fiber.

Figure 13 is a side view of the end of an external guided fishing rod according to the present invention. In this embodiment, although it is a vibration extraction type | mold which connected three of the base rod (not shown), the intermediate rod 12, and the end stand 10 by the vibration extraction method, a line system etc. may be sufficient. Each fishing rod is made of synthetic resin such as epoxy resin as a matrix, and is made of fiber reinforced resin fishing rod reinforced with reinforcing fibers such as carbon fiber. Since the rod is vibrated, the base rod and the intermediate rod are hollow tubes, but the end 10 is a hollow tube. It may be a solid lever. The top guide TG is fixed to the end stand, and in this example, guide support sheets Z1, Z2, and Z3 are provided on the outer periphery of three longitudinal directions of the end stand. In addition, the guide rod sheet | seat not shown in two places is provided in the intermediate rod 12. As shown in FIG.

The guide support sheet is formed integrally with the fishing rod by fiber reinforced resin, synthetic resin, or the like. The movement guides YG1, YG2, and YG3 can be attached to each of these guide support sheets, respectively. In addition, there are also two moving guides not shown. As mentioned above, since it is a vibration extraction type, when talking about an end stand, the movement guide YG3 mounted in the last guide support seat Z3 can pass through the front guide support seats Z2 and Z1, and it moves The guide YG2 can also pass through the guide support sheet Z1, and at the time of storage, each moving guide is gathered near the top guide TG.

14A, 14B, and 14C are partial enlarged cross-sectional views of the guide support sheets Z1, Z2, and Z3, respectively. Concave tube 0J1S of the support sheet Z1 closest to the plane H including the center of the top guide TG (not shown) and the center axis CL of the end table 10 (FIG. 16). In the present embodiment, is located on the plane (H), the concave (0J2S, 0J3S) closest to the plane (H) of the other support sheet (Z2, Z3) is also located on the plane (H), each Support sheets are at the same angular position. However, the recessed groove closest to the plane H may not be on the plane H, and the supporting sheets may be the same. The above may be substituted and expressed by convex. The pitch angles θ of each of the recesses 0J1, 0J2, and 0J3 are also the same, which is 12 degrees in this embodiment. Between the recesses, the convex tanks TJ1, TJ2, and TJ3 are formed.

Since it is as mentioned above, the circumferential pitch distance of an uneven | corrugated groove becomes longer, so that the guide support sheet of a rear position is long. Therefore, the width | variety of the downstream side of a convex tank becomes large, and when the movement guide is attached, the durability of the uneven | corrugated tank of a back support sheet improves. As shown in Fig. 14, the thickness of the guide support sheet is formed to be thicker as the support sheet at the rear position, but the thickness may be arbitrary and the same thickness may be used.

15 shows a front view of the movement guide YG1 as a representative. The same is true for other movement guides. The guide ring R1 by hard members, such as ceramics, and the mounting cylinder T1 made of synthetic resin and fiber reinforced resin are connected up and down by the frame member F1 made of metal or synthetic resin. On the inner circumference of the mounting cylinder, the convex groove TJ1 'and the concave groove which are oriented in the direction of the center axis line TC1 of a mounting cylinder are formed in fixed pitch angle (12 degree in this example). In the mounting cylinder T1, the convex part TK is provided in the outer periphery predetermined position, and the recessed part FK which accommodates this is formed in the predetermined position of the frame member F1.

By the combination of the convex portion and the concave portion, the convexity of this unevenness is convex, the convex closest to the plane H 'including the center C1 of the guide ring R1 and the center axis TC1 of the mounting cylinder T1. The bath TJl'S is located on the plane H '. The same applies to the other two movement guides YG2 and YG3. However, the convexity closest to the plane H 'may not be on the plane, and the support sheets may be at the same angular position. The above may be expressed by replacing with a recess.

When attaching the said movement guide YG1 to the guide support sheet Z1, when it carries out at the relative position which faces the predetermined | prescribed convex tank TJ1'S of a cylinder side to the predetermined recessed groove 0J1S of a support sheet side, FIG. 16, the movement guide is mounted with the plane H 'coincident with the plane H already described above. That is, the movement guide YG1 is linearly arranged with respect to the top guide TG. The same is true for other movement guides. In this embodiment, there are 30 supporting sheet side uneven grooves and 30 communicating side uneven grooves, all of which are coupled to each other so that the load acts evenly, thereby improving the durability of the uneven grooves.

17 is an enlarged longitudinal sectional view of the vicinity of the guide support sheet Z1. Although the bottom part t of many concave-convex recesses 0J1 provided in the outer periphery of the fishing rod 10 of the pointed point may be constant from the front end part to the rear end part, it may set thicker so that it may be rearward. In this example, it forms gradually thick until it reaches the rear position P2 from the position P1 of the front end part substantially, and thickly sets it in rapid taper shape until it reaches the rear end part P3 after that.

This prevents the problem that the movement guide is moved too far backward so as to fall out backward. In addition, the elevation difference (groove depth) f between the convex top surface and the concave bottom surface is substantially constant except between the positions P2 and P3, and the positions are gradually approached to zero to the positions P2 to P3. have. The same applies to other guide support sheets. As a result, the height of the concave bottom surface of the concave-convex groove becomes higher as the guide supporting sheet is rearward with respect to the center axis of the end, so that the moving guides can be pressed against each other and retained. In addition, since the groove depth is usually constant at a predetermined length in the longitudinal direction, when the mounting cylinder of the moving guide is inserted, a predetermined amount of bite engagement is sufficiently generated, and the guide support sheet can be reliably prevented from rotating to be mounted.

Although the area | region which does not form an uneven | corrugated tank is provided in the rear end of a guide base sheet, you may provide in all the area | regions. In addition, in order to make the level | step difference of the front end part and the rear end part of a guide base sheet smooth, and to mount and move a movement guide, you may provide the inclination part Z1 'by synthetic resin or paint. The same applies to other guide support sheets. This also helps to prevent stress concentration.

A method of making the groove depth f constant in the circumferential direction will be described below.

The guide support sheet is integrated outside the predetermined position of the fiber-reinforced synthetic resin fishing rod, and the guide support sheet is processed to the guide support sheet on the basis of the circular guide support sheet outer periphery, It has the process of processing the groove | stretch extending | stretching in a longitudinal direction, and many groove depth of a predetermined pitch is made constant generally in a circumferential direction.

In each of the above descriptions, a specific guide support sheet ZB is described as an example of the guide support sheet, but the other guide support sheet is the same, and the end is used as a fishing rod as an example. It is the same. Each matter described in other embodiments can be applied to other embodiments as long as there is no contradiction in particular.

As apparent from the above description, according to the present invention, in the case of a fishing rod for providing the guide support sheet in a plurality of longitudinal direction portions of the end stand, the movement guides are lined up in a straight line with high precision with respect to the top guide, It is possible to provide a fishing rod that prevents defects and improves durability. In addition, in the case of forming a guide support sheet by processing a large number of irregularities in the padding portion of the fishing rod, the depth of the groove can be made constant and can be manufactured efficiently, thereby providing a low cost manufacturing method. The fishing line guide can be reliably prevented from attaching to the guide support sheet, and can provide a fishing rod with light weight and good flexibility.
