Description

  The present invention relates to a fishing rod in which a plurality of rods formed in a hollow shape or a solid shape are joined.

In general, a fishing rod that joins a plurality of rods is known as a jointing type or inlay joining type as its joining structure. As for the former joining structure, for example, as disclosed in Patent Document 1, the proximal end portion of the soot tube located on the distal end side is fitted into the inner periphery of the distal end portion of the soot tube located on the proximal side. In this case, the pipes are joined together. In addition, the latter joint structure is, for example, as disclosed in Patent Document 2, on the inner periphery of the distal end portion of the soot tube located on the hand side, a mating plug called a spigot (cylindrical and In addition, it may be solid), and by fitting the base end portion of the soot tube located on the distal end side with respect to this spigot, the soot tubes are joined together.
Utility Model 3-105276 Japanese Utility Model Sho 63-199566

  In a fishing rod having the above-described joint structure, a spear pipe (hereinafter referred to as a hand side spear pipe) located on the proximal side and a spear pipe (hereinafter referred to as a front end side spear pipe) located on the distal end side are joined. It is difficult to accurately manage the dimensional accuracy of the part. For example, if the dimensions at the joint part become loose, the joint operation becomes easier, but when the fishing rod is bent or at the time of the casting operation, a squeak is generated from the joint part, or the tip side side pipe is at the time of the casting operation. There arises a problem that it comes out of the hand side tubule. On the other hand, if the dimensions at the joint are too tight, it will be difficult to perform the fitting operation when joining the two pipes, and will be fixed at the joint when removing both pipes. As a result, there arises a problem that it becomes difficult to remove.

  The present invention has been made based on the above-described problems, and has an object to provide a fishing rod that has a simple structure, prevents squeaking generated from a joining portion, is difficult to be fixed, and is easily joined. .

  In order to achieve the above-described object, the fishing rod according to the present invention is configured in an inlay joint type or a joint type in which a joint portion of a small-diameter rod pipe is joined to a joint portion of a large-diameter rod pipe, Provided in the region where the length of the joint portion is separated from the end of the joint portion of the small-diameter soot tube, and an inclined portion into which the large-diameter soot tube can be fitted, and the joint portion of the large-diameter soot tube It is provided in the area | region which separated the length of the said connection part from the edge part, and has a deformation | transformation part which protruded inward partially so that the said small diameter soot tube could be fitted.

  According to the configuration described above, when the large-diameter soot pipe and the small-diameter soot pipe are joined, on the distal end side of the large-diameter soot pipe, the end of the large-diameter soot pipe is fitted with the inclined portion of the small-diameter soot pipe, On the distal end side of the small-diameter soot tube, the distal end portion of the small-diameter soot tube comes into contact with the deformed portion formed in the large-diameter soot tube while being inserted. In the jointed state of the two rods, both ends of the jointed part are fitted by the inclined part and the deformed part. Will not occur.

  Also, when joining the two pipes, since the joining operation is performed while abutting the deformed part protruding inward partially, the load at the time of joining is reduced, and the joining operation is easy to perform. By providing the deformed portion, a slight gap is formed at the time of joining, and sticking is prevented.

  Furthermore, by providing a deformed part that partially protrudes inward, the inner surface of the large-diameter rod tube and the outer surface of the small-diameter rod tube are not strictly controlled (even if there is some production error). It is possible to solve problems such as squealing and sticking with a simple configuration.

  In the above-described configuration, the large-diameter soot tube is a soot tube on the side located on the outer side (female-side soot tube) in the joining portion, and the small-diameter soot tube is located on the inside in the joining portion. It is defined by the side tube (male tube). For this reason, in the spigot type fishing rod, the side rod to which the spigot is fixed becomes a small-diameter rod, and the side rod inserted into the spigot becomes a large-diameter rod. In addition, the soot tube includes a so-called tubular tube having a hollow portion formed therein, and a so-called solid tube tube having no hollow portion formed therein.

  In addition, in the above-described configuration, the deformation portion provided on the large-diameter soot tube is a shape that protrudes partially inward from the virtual circle defined by the inner surface of the large-diameter soot tube. Of course, a part where the virtual circle is partially crushed inward and the part has a substantially arc shape and the radius of curvature is equal to or smaller than the virtual circle is included. In other words, the presence of such a deformed portion allows the small-diameter soot tube to be in partial contact with the inner peripheral surface of the large-diameter soot tube on the circumference while hitting the deformable portion during the joining operation. It becomes possible.

  According to the present invention, it is possible to obtain a fishing rod that has a simple joining configuration, prevents squeaking from a joining portion, is difficult to be fixed, and is easily joined.

Hereinafter, an embodiment of a fishing rod according to the present invention will be specifically described with reference to the accompanying drawings.
FIG. 1 is a side view showing an embodiment of a fishing rod according to the present invention.
The fishing rod 1 according to the present embodiment is a two-piece spear provided with a main rod tube (hand side rod tube) 2 and a tip rod tube (tip side rod tube) 3 joined to the tip of the main rod tube 2. It is configured and mainly used as a luer rod or fly rod.

  On the base end side of the main casing 2, a grip 4 to be held and a reel sheet 5 on which a reel (spinning reel) 50 is mounted are provided. In addition, a fixed guide 7 is fixed to the outer peripheral portions of the main rod 2 and the tip rod 3 by a fixing member 22 such as a bobbin and a thread stopper so that the fishing line fed from the reel 50 is guided. . A top guide 8 is fixed to the tip of the tip tube 3.

  The main rod tube 2 and the tip rod tube 3 are formed into a tubular shape by so-called FRP in which a reinforcing fiber (carbon fiber, glass fiber, or the like) is impregnated with a synthetic resin. It is designed to be joined with an inlay joint structure.

  Specifically, a substantially cylindrical inlay (mating stopper) 10 is bonded to the distal end side of the main rod tube 2, and the tip rod tube 3 is inserted into the outer periphery of the protruding portion. For this reason, in this embodiment, the main rod tube 2 to which the spigot 10 is bonded is defined as a small-diameter rod tube in the claims, and the tip rod tube 3 is defined as a large-diameter rod tube in the claims.

  In the projecting portion of the inlay 10 from the main rod tube 2, the region indicated by the symbol R becomes a joint portion of the main rod tube (small-diameter tube) 2, and the tip tube (large-diameter tube) 3 is joined. Part. That is, the region indicated by the symbol R is the joint length (the length of the joint portion) of the two pipes.

  The inlay 10 is formed with a straight portion 10a extending in the axial direction from the end portion P1 to the length of the joint portion, and in the region separated from the end portion P1 by the length R of the joint portion. An inclined portion 10b having a predetermined length is formed along the axial direction. In this case, the inclined portion 10b is formed in a taper shape that gradually increases in diameter from the end portion P1 side, and when the tip tube 3 is fitted, the opening 3a contacts and is fixed over the entire circumference. It has become so. For this reason, the sloping part 10b of the spigot 10 is in an exposed state at the time of joining the two steel pipes.

  And as shown in FIG. 3, the deformation | transformation part 20 which has predetermined length along an axial direction exists in the area | region which separated the length R separation of the joint part from the edge part P2 of the joint part of the tip rod tube 3 Is provided. The deformed portion 20 has a shape in which an inner peripheral surface thereof partially protrudes inward so that the main casing 2 (inlay 10) can be fitted.

  In consideration of a virtual circle defined by the inner peripheral surface of the tip tube 3, the deforming unit 20 only needs to have a region that partially protrudes inward with respect to the virtual circle. For example, the shape which protrudes so that the inner peripheral surface of the tip tub tube 3 may partially bulge inward, or the inner peripheral surface is partially inward by pressing the tip tub tube 3 from the outside. The shape may be a shape in which a portion of the virtual circle is crushed and substantially arc-shaped and the radius of curvature is equal to or smaller than that of the virtual circle.

  For the deformed portion 20 having the shape like the latter, for example, when the tip tube 3 is formed, an arc-shaped surface is formed in advance on a part of the outer peripheral surface of the core metal for molding by milling, It is possible to form a prepreg sheet around this mandrel, and then form it by a conventional method such as heating or decentering. Alternatively, it can be formed by fixing a fixed guide 7 through which the fishing line is inserted into a corresponding portion of the outer peripheral surface of the tip rod 3 as follows.

  The fixed guide 7 is formed of an insertion portion 7a through which a fishing line is inserted, and a material harder than the tip rod tube 3, and the leg back side has an arc shape and a radius of curvature is greater than a radius of curvature of the mounting portion tip rod outer periphery. 3 and a small leg portion 7b, and, as shown in FIG. 3, the leg portion is located in a corresponding portion of the panicle tube 3 (the region between the joining portion end P2 and the joining portion length R). It is possible to form the deformed portion 20 by placing the leg portion 7b and fixing the leg portion 7b with a fixing member 22 (thread winding with cotton thread, thread stopper coated with epoxy, urethane paint or the like) 22. That is, since the leg portion 7b is formed of a material (SUS, brass, titanium alloy, etc.) harder than the tip tube 3, the leg member 7 is pressed by fixing the leg portion 7b by the fixing member 22. And it becomes possible to form the deformation | transformation part 20 by bulging the area | region toward the inner peripheral surface as it is.

  Specifically, as shown in FIG. 4, the curvature radius r <b> 1 of the inner surface shape of the deformable portion 20 becomes a substantially circular arc shape that is equal to or smaller than the curvature radius r <b> 2 of the inner peripheral surface of the tip rod tube 3 that is the virtual circle C. It becomes possible to form. And in the deformation | transformation part 20 of such a shape, when the tip tub tube 3 is joined with the inlay 10, the outer peripheral surface of the inlay 10 and the inner peripheral surface of the tip tub tube 3 are partially on the circumference. The state in contact with is maintained.

  As shown in FIGS. 5A and 5B, this contact portion is a region C1 to which the fixed guide 7 is fixed. Therefore, in the region C2 which is the opposite direction (diameter opposite side), It becomes the contact portion where the reaction force acts. That is, the end portion of the joint portion of the main rod (inlay 10) is in partial contact with the inner peripheral surface of the tip rod tube 3 in the regions C1 and C2, and has a backlash (vertical length) in the C1 and C2 directions. (Backlash in the direction) can be suppressed, and backlash in the direction orthogonal to the C1 and C2 directions (lateral backlash) can be effectively suppressed.

  As described above, when the main tub tube 2 to which the inlay 10 is fixed and the tip tub tube 3 are joined, the opening 3a at the end portion P2 of the head tub tube 3 is inclined at the rear end side of the head tub tube 3. In contact with and fixed to the portion 10b over the entire circumference, and at the distal end side of the main rod tube 2, the tip portion of the main rod tube 2 (inlay 10) was formed on the tip rod tube 3 in accordance with the insertion operation. While coming into contact with the deformable portion 20, finally comes into contact with each other in the circumferential direction.

  Thus, in the joint state of both the rod pipes 2 and 3, since both ends of the joint portion are fitted by the inclined portion 10b and the deformable portion 20, the fishing rod is bent or is subjected to a casting operation. In this case, rattling is suppressed and no noise is generated. In addition, when joining the two pipes, since the joining operation is performed while being in contact with the deformable portion 20 that partially protrudes inwardly, the load at the time of joining is reduced and the joining operation is easy to perform. By providing the deforming portion 20 that partially protrudes inward, at the time of joining, a slight gap is formed around the deforming portion or between the inclined portion 10b and the deforming portion 20, Adherence is prevented.

  In particular, in the luer rod and fly rod, the mounting position direction of the fixed guide 7 and the casting direction coincide with each other, and the casting operation is performed along the diameter direction including the above-described regions C1 and C2. It is difficult for squeal to occur.

  Moreover, since the above-mentioned deformation | transformation part 20 can be formed by fixing the fixing guide 7 in the position spaced apart only by the joining length R from the edge part of the tip tub tube 3, even if the dimension in a joining part varies Both rods can be securely fixed, and a fishing rod can be obtained with a very simple configuration that prevents the occurrence of squealing and sticking.

  In this case, the radius of curvature of the inner surface of the leg 7b of the fixed guide 7 is smaller than the radius of curvature of the outer surface of the attachment position of the scissors cannula 3 so that the above-described substantially arc-shaped deformed portion 20 is formed. It is preferable to be formed as follows. Further, the leg portion 7b preferably has a maximum thickness in the range of 0.9 to 1.6 mm and a width of 2.5 to 5.5 mm in consideration of the durability and strength of the guide. .

  In addition to fixing the fixed guide 7, the above-described deformable portion 20 is configured by fixing a plate-like member (metal member) formed of a material harder than the tip tube 3 with a similar fixing member. It may be formed. The plate-like member may have a circular arc shape that is curved toward the side of the tubule contact portion.

  Moreover, it is preferable that the above-mentioned deformation | transformation part 20 is formed so that the following aspects may be obtained when both the pipes 2 and 3 are joined.

  As shown in FIG. 6, it is preferable that the end portion P <b> 1 in the joining portion of the main rod tube 2 is located within the length range R <b> 2 of the deformed portion 20 in the tip rod tube 3. The length range R2 of the deforming portion 20 is a length of deformation caused by pressing of the leg portion 7b of the fixed guide 7, and can be easily obtained depending on the position where the fixed guide 7 is fixed.

  According to such a structure, since the deformation | transformation part 20 is pressing the inlay 10 of the main shaft 2 reliably, it becomes difficult to generate a squeal.

  In addition, in the longitudinal direction region other than the deformed portion 20, if the gap T between the inner surface of the tip rod tube 3 and the outer surface of the spigot 10 of the main rod tube 2 is too wide, rattling occurs and squealing is likely to occur. Therefore, it is preferably set to be less than 0.01 mm. The gap T can be adjusted as appropriate depending on the thickness of the tip tube 3 to which the fixed guide 7 is fixed, the tightening force of the fixing member 22, and the like.

  Furthermore, as shown in FIG. 3, it is preferable to provide a reinforcing member 30 on the outer periphery of the end portion of the joining portion of the tip-ear tube 3. The reinforcing member 30 can be formed of, for example, a circumferential fiber-like or ring-shaped metal, resin, or the like. By providing such a reinforcing member, the end portion of the tip tube 3 is provided. It is possible to prevent cracking and the like, and it is difficult to cause variations in the fitting force with the inclined portion 10b, and it is possible to reliably prevent the occurrence of sticking.

  FIG. 7: is a figure which shows the 2nd Embodiment of this invention, and is sectional drawing which expands and shows the joining part of tubules.

  As described above, the present invention can be applied to a side-by-side type fishing rod in addition to an inlay joint type fishing rod. In the side-by-side fishing rod, an inclined portion 32a into which the large-diameter rod 33 can be fitted is formed in the region between the end portion P3 of the joining portion of the small-diameter rod 32 and the length R of the joining portion. Yes. The inclined portion 32a is formed as a taper that gradually increases in diameter from the end portion P3 toward the tip, and the opening 33a of the large-diameter rod 33 is in contact with the circumferential direction.

  Further, in the region between the end portion P4 of the joint portion of the large-diameter rod pipe 33 and the length R separation of the joint portion, the fixing guide 7 is fixed by the fixing member 22 as in the above-described embodiment. A deformable portion 40 that protrudes partially inward is formed so that the outer periphery of the rear end of the small-diameter rod 32 can be fitted. The deformed portion 40 is formed to have a substantially arc shape that is equal to or smaller than the radius of curvature of the inner peripheral surface of the large-diameter rod tube 33, and is applied to the deformable portion 40 when the small-diameter rod tube 32 is jointed. In addition, the outer peripheral surface of the small-diameter soot tube 32 and the inner peripheral surface of the large-diameter soot tube 33 are maintained in a state of being in partial contact with each other on the circumference.

  In such a side-by-side type fishing rod, similarly to the above-described embodiment, in the joined state of the two rods 32 and 33, both ends of the joined portion are fitted by the inclined portion 32a and the deformable portion 40. Therefore, when the fishing rod bends or performs a casting operation, rattling is suppressed and no squeal is generated. In addition, when joining the two pipes, since the joining operation is performed while being in contact with the deformed portion 40 that partially protrudes inwardly, the load at the time of joining is reduced and the joining operation is easy to perform. By providing the deforming portion 40 that partially protrudes inward, a slight gap is formed between the inclined portion 32a and the deforming portion 40 at the time of joining, preventing sticking Is done.

  Of course, also in this embodiment, various configurations in the first embodiment described above may be applied.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.

  For example, the shape and the forming method of the deformed portions 20 and 40 described above can be modified as appropriate. Further, the present invention may be applied to a fishing rod that is not equipped with a fixed guide, or may be applied to a fishing rod that joins a plurality of rods.
