Description

  The present invention relates to a fishing rod provided with a movable external fishing line guide (moving outside guide).

An example of a structure for mounting and fixing a non-moving guide for the swing type is disclosed in Patent Documents 1 and 2 listed below by the applicant. These are the same as the concave / convex pitch of the receiving seat provided on the vertical tube and the concave / convex pitch of the mounting cylindrical portion of the outer guide, and the top of the cylindrical ridge contacts and presses the bottom of the receiving concave. The outer guide is held and fixed by the frictional force of
JP 2004-81079 A JP 2004-81080 A

However, when the engagement between the recess on the receiving side and the protrusion on the movable guide tube portion side is seen in a cross section, the protrusion side portion has a positive gap between the recess. It is set to form, and it is simply engagement with the frictional force that the top of the ridge contacts the bottom of the ridge, and the fishing rod is bent and deformed during fishing, from the fishing line inserted through the guide Since it receives force in various directions (left and right and up and down), it is easy to rotate unintentionally. In addition, considering only increasing the holding and fixing force to prevent inadvertent rotation, there is a problem of sticking, and it is difficult to remove the outer guide (moving forward when closing, etc.). Become.
Therefore, the problem to be solved is to provide a fishing rod having a mounting and fixing structure capable of stably holding and fixing the outer moving guide to be mounted on the fishing rod and preventing sticking.

The invention according to claim 1 is a fishing rod in which an outer guide is movably provided, and there are K ridges and ridges on the inner periphery of the mounting cylinder portion to the tub tube of all or part of the moving outer guides. Are arranged at equal pitches in the circumferential direction, and the receiving seat for the moving outer guide enters the cylindrical build-up layer on the surface of the vertical tube, and the outer periphery of the layer enters the recess of the moving outer guide mounting tube portion. L ridges that can be engaged are provided at equal pitches, K is an integer of 2 or more of L, and the radial direction in the vicinity of the top position of the side surface of each of the K ridges of the mounting cylinder portion The inclination angle is in the range of 10 degrees to 50 degrees, and the inclination angle with respect to the radial direction in the vicinity of the top position of the side surface of each convex strip of the outer guide for moving guide is in the range of 10 degrees to 50 degrees, The front portion of the outer guide for the moving guide has a smaller diameter than the rear portion, and at the position where the outer guide is mounted and fitted, In some cases, the top part is in contact with the concave bottom surface of the mounting cylinder part, and in the convex line of the mounting cylinder part, the top part is in contact with the concave bottom surface of the seat. There is provided a fishing rod with an outside guide, characterized in that there is.
The vicinity of the top position means that the corner may be rounded at the intersection of the side surface and the top surface, and this means the position excluding this rounded portion.
According to a second aspect of the present invention, there is provided a fishing rod with a movable outer guide according to the first aspect, in which the magnitude relationship between the number of concave and convex stripes in the movable outer guide and its seat is reversed.

According to a first aspect of the present invention, the structure of the outer guide is such that two or more seat-side ridges intrude and engage with the concave portion on the cylindrical portion side, Adjacent ridges have predetermined inclination angles and the two or more seating side protrusions face each other at predetermined inclination angles, thereby preventing inadvertent rotation. In addition to this, at the position where the cylindrical portion of the outer guide is moved and fitted backward from the small-diameter front portion of the seat, the top portion of the convex portion of the seat is the cylindrical portion. There are some that are in contact with the bottom surface of the groove, and some of the protrusions of the cylinder part are in contact with the bottom surface of the groove of the seat, so this frictional force can cause The guide can be prevented from slipping forward, and the holding and fixing can be stabilized. In addition, since the number of the ridges on the tube side is less than half of the ridges on the receiving side (projections), more than half of the ridges on the side of the receiving side has The frictional force can be reduced accordingly. This reduces the number of contacts (area) in order to prevent the frictional force for mounting and fixing from becoming excessively large and preventing the outer guide from moving forward when it is pulled out (moved).
In the second aspect, the same effect as in the first aspect is obtained.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a swing type fishing rod with an outer guide according to the present invention, FIG. 2 is an enlarged view of a region mainly composed of a tip rod (directions are reversed from side to side), and FIG. FIG. 4 is an enlarged partial cross-sectional view and an exploded view of the guide G1 at the mounting and fixing position, and FIG. 4 is a partial enlarged view of FIG. The fishing rod is a combination of a hook rod 10, a hoji rod 12, a first middle rod 14, a second middle rod 16, and a main rod 18 in a swing-out manner, and each rod tube is made of a synthetic resin such as an epoxy resin made of carbon fiber. It is made of fiber reinforced resin reinforced with reinforcing fibers such as.

  Fixed outer guides GT, KG, KG, KG, and KG are attached to the distal end portions of the respective tubules 10, 12, 14, 16, and 18, and the other outer guides are movable outer guides that can be moved. . Three first-type movement outer guides G1 are mounted on the head rod 10 immediately after the fixed top guide GT, and one second-type movement outer guide G2 is mounted immediately thereafter. Two second-type moving out-of-movement guides G2 are mounted on the hot pot 12 immediately after the fixed guide KG. Each of the intermediate collars 14 and 16 is provided with one other type (third type) of outer movement guide G3. Therefore, the moving outer guides excluding the fixed outer guide are arranged in the order of the first type, the second type, and the third type from the front part. This second type movement outer guide is the movement outer guide according to the present application. The outer guide and its receiving structure may be used in place of the third type moving outer guide and its seat structure at the position of the third type moving outer guide.

The seats Z1 and Z2 for mounting and fixing the above-mentioned first type and second type moving outer guides are wound together by pressurizing and firing the fiber reinforced resin prepreg pieces together when thermo-molding the soot tube material. After forming the receiving annular layer material laminated integrally with the tube and grinding it to the circular outer periphery with high precision to form the receiving annular layer, the groove groove is ground as described later, and as a result It becomes the form which provided the uneven | corrugated strip on the surface of the cylindrical build-up layer (base layer of the uneven strip). As the reinforcing fiber of the receiving annular layer material, a carbon fiber having an elastic modulus of 5 t / mm ² (49000 N / mm ² ) or less, for example, 1 t / mm ² (9800 N / mm ² ) is preferable. For example, a unidirectional assembling sheet obtained by impregnating a reinforcing fiber obtained by aligning carbon fibers in one direction with an epoxy resin is used. The orientation direction of the carbon fiber is the longitudinal direction of the soot tube, and the rigidity of the soot tube is increased by using a prepreg using a low elastic modulus reinforcing fiber, and the strength and durability are improved by the longitudinal fiber. It becomes possible. Further, the lengths of the respective seats Z1 and Z2 are longer than the lengths of the mounting cylinder portions G1T and G2T of the outer guides G1 and G2.

  On the inner side of the mounting cylinder portion G1T of the first type moving outer guide G1, the ridges TT and the ridges TK are provided on the inner periphery at equal pitches, and nylon, ABS resin, polyacetal resin (POM resin) An annular body G1T ′ made of synthetic resin such as polycarbonate is fixed and held. That is, N convex strips TT and concave strips TK made of synthetic resin are provided at equal pitches on the inner periphery of the mounting cylinder portion. In this case, the number N is 20, and the corrugated tube side receiving seat Z1 corresponding to this has M convex ridges ZT that can enter and engage with the concave TK at an equal pitch in the circumferential direction. In this case, M is 10, and is 1/2 of N (20). Further, a concave line ZK is formed between the convex lines ZT. The top of the receiving-side ridge ZT is a circular arc surface (generally flat) concentric with the vertical tube 10, and the cross-sectional shape of the ridge ZT is generally trapezoidal. On the other hand, the cross-sectional shape of the ridge TT is a generally triangular shape with rounded tops.

  FIG. 4 shows a mounting and fixing state in which the protrusion ZT enters and engages with a certain groove TK1, but both side surfaces of the protrusion ZT have protrusions TT1 and protrusions on both sides that define the groove TK1. It is in a pressed state with the side surfaces facing TT2. In this case, since the receiving-side ridge ZT does not correspond to the concave TK2 between the ridge TT2 and the convex TT3, the convex TT2 is deformed so as to approach the direction of the adjacent convex TT3. Is possible. The same applies to the ridge TT1. Accordingly, the receiving side ridge ZT is sandwiched between the side surfaces of the two adjacent ridges TT1, TT2, and is thus firmly held and fixed. In this case, the top of the ridges on each side may or may not contact the bottom of the mating ridge. In this example, there is no contact.

  The state shown in FIG. 4 is a state of the mounting and fixing state. As described above, the seat is longer than the mounting cylinder portion of the outer guide, and its front portion is formed to have a smaller diameter than the rear portion. Therefore, when the outer guide G1 is moved from the front to the rear, and can be easily inserted into the small-diameter front portion first, and moved to the rear and comes to the relatively large-diameter rear portion, the seat is received as described above. Since the side ridge ZT is sandwiched between the side surfaces of the two adjacent ridges TT1, TT2, a force for holding and fixing firmly is generated. As a result, even if the tip is repeatedly bent greatly, the movement-out guide is difficult to loosen. In addition, since the receiving side protruding ridge and the two cylindrical portion side protruding ridges sandwiching the receiving side are in contact with each other, inadvertent rotation in the circumferential direction can be prevented and stable.

  As a form in which the front part of the seat is made smaller in diameter than the rear part, the diameter is gradually increased from the front end of the seat toward the rear, and a substantially constant outer diameter part is provided on the way, or the front end (near) For example, a constant outer diameter having a small diameter from the middle to the middle position is then increased, and then the diameter is gradually increased rearward, and a large-diameter outer diameter portion having a substantially constant outer diameter is provided again.

  FIG. 5 is an enlarged cross-sectional view and an exploded view of the second type movement outer guide G2 of FIG. 2 at the mounting and fixing position, and FIG. 6 is a partial enlarged view of FIG. On the inner side of the mounting cylinder portion G2T of the second type moving outer guide G2, convex TT and concave TK are provided on the inner circumference at an equal pitch, and nylon, ABS resin, polyacetal resin (POM resin) An annular body G2T ′ made of synthetic resin such as polycarbonate or other is fixedly held. In other words, K convex strips TT and concave strips TK are provided at an equal pitch on the inner periphery of the mounting cylinder portion. In this case, there are eight K pieces, and the corresponding side Z2 on the side of the tub tube has L ridges ZT at equal pitches in the circumferential direction. In this case, L pieces are 16, and K pieces (8 pieces) are 1/2 of L pieces (16). Further, a concave line ZK is formed between the convex lines ZT.

  As shown in FIG. 6, in the mounting and fixing position, the top of the receiving side ridge ZT abuts on the bottom surface of the cylindrical side concave TK, and the top of the cylindrical side ridge TT is the bottom of the receiving side concave ZK. Abut. This is because even if there is a slight gap between the bottom and the top due to dimensional accuracy in manufacturing, at least one of the ridges is compressed by the force for moving and mounting the outer guide, and the slight gap can be absorbed. Because. However, depending on the overall manufacturing accuracy, not all of the ridges on the entire circumference are in contact with the bottom surface of the mating recess, and the present application allows the case where there is something that does not contact. The top of the receiving side ridge ZT is a circular arc surface (substantially flat) concentric with the rods 10 and 12, and the cross sectional shape of the ridge ZT is substantially trapezoidal. The tube portion side ridge TT has a circular arc surface or a plane shape concentric with the tube portion G2T (or the annular body G2T ′), and the cross section of the ridge TT is substantially trapezoidal. The bottom surface of the receiving recess ZK is a flat surface or a circular arc surface concentric with the rods 10 and 12, and the cylindrical groove TK is a circular arc surface or plane concentric with the cylindrical portion G2T (or the annular body G2T ′). Is.

  The top of the receiving-side convex strip ZT is in contact with the bottom surface of the cylindrical-side concave strip TK, but the number L of concave-convex strips on the receiving side is 16, and the number of concave-convex strips on the cylindrical portion side is K. Since there are eight, the cylindrical portion side protrusions TT are in contact with one of the two receiving side recesses ZK alternately. This reduces the sticking force due to pressure contact and leads to sticking prevention. In other words, the second type movement outer guide G2 is not used as the movement outer guide at the foremost part of the fishing rod, but one or more of the first type movement outer guides G1 described above (in this example, 3) Used for the front part, and used for the rear area of the second type movement outer guide G2. Accordingly, the outer diameter of the soot tube at the mounting position is larger than that of the first type, and the necessity of preventing sticking is usually increased in a seating region having an outer diameter of about 5 mm or more, and the effect is enhanced.

  Moreover, the angle θ formed by the tangent (tangent plane) at the intersection of the top surface and the side surface of the ridge TT in this example and the radial line of the soot tube is 45 degrees. The angle Θ formed by the tangent (tangent plane) at the intersection of the top surface and the side surface of the ridge ZT and the radial line of the soot tube is 45 degrees. Therefore, even if a force for rotating the outer moving guide G2 is applied, the side surface of the receiving-side convex strip cannot be overcome. For this reason, inadvertent rotation of the out-of-movement guide G2 can be prevented. The ranges of the angles θ and Θ are 50 degrees to 10 degrees, respectively. Preferably, it is about 45 to 10 degrees.

  As described above, the seat Z2 is longer than the mounting cylinder portion of the outer guide, and its front portion is formed to have a smaller diameter than the rear portion. Accordingly, the outer moving guide G2 is moved from the front to the rear, and can be easily inserted into the small-diameter front portion first, and is moved rearward to come to the rear portion having a relatively large diameter to be in a fixed state. The form in which the front part of the seat is made smaller in diameter than the rear part is the same as in the case of the first type described above.

  FIG. 7 is a view showing a modified example of the second type moving outer guide, and is a partially enlarged cross-sectional view in a state of being mounted and fixed. What is different from those described with reference to FIGS. 5 and 6 is only the magnitude relation of the number of the ridges and recesses, and the other is the same as the above description. That is, the number of protrusions and recesses on the side of the seat Z2 is eight, and the number of protrusions and recesses on the cylinder side (annular body G2T ′ side) is 16. Also in this case, the same effect as the embodiment described with reference to FIGS.

  The ridges on the tube side can be formed by broaching. On the other hand, the recesses and projections on the receiving side grind the receiving annular layer as shown in FIG. That is, on the surface of the circular annular layer processed into a highly accurate circular shape, the groove groove extending in the longitudinal direction of the pipes 10 and 12 is ground at a predetermined pitch in the circumferential direction, and as a result, the protrusion is also formed. Form. When grinding the groove, the cylindrical portion E near the rear end of the seating annular layer surface is held by the chuck TK, and the vertical tube is held in the horizontal direction. In this case, a groove groove oriented in the longitudinal direction is ground on the upper surface side of the receiving annular layer while rotating the tool (milling) TL shown in FIG. Of course, the grinding is performed along the surface of the annular seat layer in which the front portion has a small diameter and the rear portion has a large diameter. In this processing, a receiving unit UK for receiving the lower surface side of the receiving annular layer may be provided so that the soot tube does not bend. Next, while the seating annular layer is held by the chuck TK, the adjacent groove is similarly ground by rotating a predetermined pitch. This is repeated thereafter. Thereby, seats Z1 and Z2 are formed.

  Instead of rotating the chuck TK, the chuck is loosened, the rod is rotated by a predetermined pitch angle by other means, and the same cylindrical portion E is held again in this state, and the groove is machined with the tool TL. May be. In any case, what is held by the chuck is the cylindrical portion E which is a part of the outer peripheral surface of the receiving annular layer, not the outer peripheral surface of the soot tube itself. In this way, a part of the outer peripheral surface of the receiving annular layer that is ground into a highly accurate cross-sectional circle is held, and a groove having a predetermined depth is processed on the outer peripheral surface with the tool TL.

  In this machining method, even if the seating annular layer that is the object of grooving is rotated (together with the soot tube), the outer peripheral surface of the seating annular layer is a highly accurate circle. The incision depth of the TL is the same as that at the beginning even if it is applied as it is without re-setting the measurement etc. in each part of the outer peripheral surface where the tool faces the receiving annular layer after being rotated by an arbitrary angle. The same depth of cut is obtained. That is, during the grooving, the circular outer peripheral surface of the receiving annular layer with high accuracy is always held, so that the groove depth by the tool TL can be always constant regardless of the rotation angle.

  The tool TL used in the above example is shown in a side view in FIG. 9 (b). The cutting tool HA is attached to the tip of the rotating shaft JK, and the cutting tool HA is fixed by the fixing portion KB at the tip of the rotating shaft. Yes. (A) is a front view. The shape of the groove is determined by the cross-sectional shape of the blade HA.

  Unlike the case of FIG. 8, you may provide an uneven | corrugated strip in the full length of a receiving annular layer. In this case, the chuck needs to hold the receiving annular layer so as to be sandwiched from above and below and from the left and right, and to provide an open portion on the outer side of the chuck so that the outer peripheral surface of the receiving annular layer is exposed. A cutting amount is set with respect to the outer peripheral surface of the receiving annular layer exposed at the open portion, and a tool blade is brought into contact with the outer peripheral surface to form a longitudinal groove along the entire length of the outer peripheral surface.

  After processing one groove, rotate it for each chuck, or loosen the chuck, rotate it by a predetermined angle, hold the receiving annular layer with the chuck again, and process another groove, repeat. Accordingly, when the groove is processed over the entire circumference, the processed uneven strip portion may be held. This processing apparatus can be replaced with a general milling machine. In the case of this method as well, the outer periphery of the circular seating annular layer (in some cases, the surface of the remaining projecting ridges on the outer periphery of the circular seating annular layer) is the same as the method of forming the projections and recesses described in FIG. Therefore, it is easy to make the depth of each groove constant.
