Description

  The present invention relates to a fishing rod, and more particularly, to an intermediate fishing rod having a fishing line introduction portion for introducing a fishing line from the outside to the inside of the rod pipe through a fishing line introduction hole formed through one side of the rod pipe.

  In general, in the case of a through-hole fishing rod in which the fishing line is guided to the tip of the fishing rod, the fishing line fed from the fishing reel is formed by forming a fishing line introduction hole in the main rod to which the fishing reel is attached. A fishing line introducing portion is provided for guiding the fishing line from the fishing line introducing hole to the inside of the rod. It is necessary for the threading rod having such a fishing line introducing portion to ensure the convergence of the fishing line discharged from the fishing reel, to reduce the resistance to the fishing line, and to prevent the occurrence of entanglement.

Such a through fishing rod includes a guide frame that guides the road thread to the inside of the rod and is attached to the outer periphery of the fishing rod, and an oval guide ring is fitted on the front side of the guide frame (for example, Patent Document 1).
JP-A-8-9842

  However, in such a through fishing rod, even if it has an oval guide ring, it guides to a tubular road thread introduction body that enters while being inclined backward in the rod pipe. A small-diameter guide ring is also provided at the inner end of the yarn introduction body. Even if this guide ring has a large opening area, it does not improve the convergence of the fishing line fed out from the fishing reel, nor does it reduce the introduction resistance of the fishing line. Furthermore, in order to thread the fishing line, a threading tool having a flexible wire structure is required to insert the fishing line along a complicated path from the oval guide ring through the tubular road thread introduction body. It becomes.

  The present invention has been made based on such circumstances, and it is an object of the present invention to provide a penetrating fishing rod that is easy to insert a threading tool and has little resistance to insertion of a fishing line into a rod.

  The through-hole fishing rod of the present invention that achieves the above object has a fishing line introduction hole formed on one side of a large-diameter rod pipe that swings and joins the tip side fishing pipe, and an edge between the front side and the rear side of the fishing line introduction hole. Cover the part with a hard ring member, and through this fishing line introduction hole, it has a fishing line introduction part that introduces the fishing line from the outside to the inside of the large-diameter rod pipe, and is formed from the fishing line introduction part to the butt plug of the tip side side pipe A fishing rod through which the fishing line is inserted from the fishing line insertion hole to the tip side. The fishing line introduction portion extends from the front side of the fishing line introduction hole to the rear side beyond the fishing line introduction hole. A fishing line guide formed with a ring holding portion for holding a fishing line guide ring is disposed at a position rearward and spaced apart from the one side of the large-diameter rod. The guide ring is held by the ring holding portion. The inner surface closest to the large diameter pipe is only in contact with the inner side of the ring member on the front side. A common tangent line that contacts the outer side of the rear ring member and an extension of the rear side tangent line that extends from the portion facing the fishing line insertion hole at the open end of the butt plug of the tip side side pipe and contacts the outer side of the rear ring member It arrange | positions in the range of the angle which a line | wire forms, and it arrange | positions in the range which forms the distance of 20 mm-30 mm between inner surfaces most spaced apart from the large diameter soot pipe.

  The innermost surface that is farthest from the large-diameter rod is the rear tangent and the front tangent that extends from the portion facing the fishing line introduction hole at the butt plug opening end of the tip-side rod and contacts the inside of the ring member on the front side. It is preferable to arrange | position within the range of the angle which each extension line | wire forms.

  Moreover, it is preferable that the said guide ring is protruded and hold | maintained back from a ring holding part over the perimeter.

  The guide ring is preferably formed in an oval shape having a long axis extending in a direction intersecting the axis of the large-diameter rod, and the length of the long axis is more than twice the length of the short axis. It is preferable.

  According to the through-hole fishing rod of the present invention, the inner surface of the guide ring closest to the large-diameter rod is in contact with the inner side of the front ring member and the outer side of the rear ring member; From this guide ring, it is arranged within the range of the angle formed by each extension line with the rear tangent line extending from the portion of the plug opening end facing the fishing line insertion hole and contacting the outside of the rear ring member. When the fishing line is threaded, since it is straight and does not have a bent portion, the threading tool hardly receives insertion resistance and is easy to insert.

  The inner surface that is farthest from the large-diameter soot tube is disposed within the range of angles formed by the extension lines of the rear tangent line and the front tangent line, so that these front or rear ring members and guide rings The threading tool is supported at two points, and can be smoothly inserted while being guided.

  Further, when the guide ring protrudes rearward from the ring holding portion over the entire circumference, the fishing line is smoothly guided while directly contacting the guide ring without contacting the ring holding portion.

  When this guide ring has an oval shape, the inner surface of the guide ring closest to the large-diameter rod is brought close to the rod, while the opposite end is separated from the rod, thereby inserting the threader In addition to improving the performance, the resistance acting on the fishing line can be reduced, and the convergence of the fishing line can also be improved.

  1-3 illustrate a threaded fishing rod 10 according to a preferred embodiment of the present invention.

  As shown schematically in FIG. 1, the through-hole fishing rod 10 of the present embodiment has a large-diameter rod 12 that is a main rod provided with a grip portion 12 a and a bottom plug 12 b on the rod tail side. , Having a scissors tube 14 that is a first spear tube with a top guide 14a attached to the spear side, and a scissors tube 16 that is a second spear tube and a third spear tube in this order from the spear tube 14 to the buttock side. It is formed by joining the middle rod 18 that is a tube and the former rod 20 that is the fourth rod. These first to fourth rod pipes 14, 16, 18, and 20 are swing-out structures joined at joint portions P1 to P4 between the base outer peripheral surface and the tip inner peripheral surface, It is stored in the tube 12. Each of these soot tubes is formed through a normal process such as curing and decentering after a fiber reinforced prepreg (FRP) in which a reinforcing fiber is impregnated with a synthetic resin is wound around a cored bar.

  The number of tubs between the large tub tube 12 and the tip tub tube 14 is not limited to the above three. Further, for example, the second and third soot pipes may be omitted and the second soot pipe 16 may be joined to the large-diameter soot pipe 12, and the large-diameter soot pipe 12 and the fourth soot pipe 20 may be connected in parallel. For example, a joint structure may be partially adopted. Further, the shape of the grip portion 12a and the like formed on the large-diameter soot tube 12 is not limited to the illustrated one. Furthermore, it is also possible to provide an original soot tube behind the large-diameter soot tube 12.

  The large-diameter rod 12 of the present embodiment is provided with a reel sheet 22 for fixing various fishing reels (not shown). A fishing line extending from the reel is placed on the tip side from the side to the inside of the rod. A fishing line introducing portion 24 to be introduced is provided.

  FIG. 2 shows a state in which the fourth soot tube 20 is shaken out from the large-diameter soot tube 12 and joined and locked at the joining portion P4. The first soot pipe 14 to the third soot pipe 18 are accommodated in this fourth soot pipe 20 in order, and are formed of a suitable material such as ABS or polyacetal attached to the rear end of the fourth soot pipe 20. The stopper 26 is supported by the stopper 26 and is secured by a fishing rod protection cover 28 attached to the tip. An insertion pipe 30 extending through the end wall 28 a is fixed to the fishing rod protective cover 28, and the tips of the second to fourth rod pipes 16 to 20 are brought into contact with the end wall 28 a via a buffer material 29. When this is done, the insertion tube 30 is inserted into the second soot tube 16 and comes into contact with the top guide 14 a of the first soot tube 14. The first soot tube 14 is prevented from being pulled out of the second soot tube 16 by the insertion tube 30. Reference numeral 32 denotes a fixture that is, for example, a belt member for fixing the fishing rod protection cover 28 to the distal end side of the large-diameter rod tube 12 or the fourth rod tube 20.

  Thus, when the 4th rod 20 which is a tip side rod is joined to the front side of the large diameter rod 12 in a swinging state, the fishing line introduction hole 12c formed in the fishing line introduction part 24 is opened, and the large diameter The space inside the tub tube 12 is opened to the outside. The fishing line introducing hole 12c formed in the fishing line introducing portion 24 is formed through the side wall of the large diameter rod 12 and has an oval shape in which the long axis is arranged along the direction of the axis 13 of the large diameter rod 12. Have. Hard ring members 34a and 34b are arranged on the peripheral edge of the fishing line introduction hole 12c, as shown by the front ring member 34a and the rear ring member 34b. A fishing line guide 36 is fixed on the front side of the fishing line introduction hole 12c.

  The fishing line guide 36 has a structure in which, for example, a guide frame 36a made of a metal plate such as stainless steel and a guide member 36b made of synthetic resin are overlapped, and the fixing portion 37a on the front side has a large diameter in this embodiment. A fixing screw 38b is screwed into a fixing block 38a that is secured to the inner surface of the rod 12 so as to be fixed to the front side of the fishing line introduction hole 12c. The fishing line guide 36 extends a guide frame 36a and a guide member 36b from the fixed portion 37a beyond the fishing line introduction hole 12c to the rear side of the large diameter rod 12 and away from the large diameter rod 12. A ring holding portion 37b is integrally formed at the side end.

  The fishing line guide 36 is held in a cantilever manner with respect to the large-diameter rod 12 by a fixing portion 37a. The ring holding portion 37b that holds the guide ring 40 on the rear side of the fishing line introduction hole 12c is disposed away from the large-diameter rod 12. An appropriate gap S may be formed between the ring holding part 37b and the large-diameter soot tube 12. When such a gap S is provided, when a load is applied to the large-diameter rod 12, it is possible to prevent the fishing line guide 36 from interfering with the ring holding portion 37 b in particular. It is possible to prevent a large stress from being formed in the fishing line introducing portion 24. In addition, when forming such a gap | interval S, it is preferable to enlarge so that it may expand gradually toward back and it may be formed so that the fishing line which entered the inside may not be latched in this gap | interval S. Further, for example, a suitable material such as a flexible elastic material may be filled in the gap S so that the fishing line does not enter the gap S.

  As shown in FIGS. 2 and 3, the guide ring 40 held by the ring holding portion 37b is formed of an abrasion-resistant hard material such as ceramic. The guide ring 40 is formed in an oval shape as a whole, the inner surface forming the inner hole 42 is formed with a smooth curved surface, and the guide frame 36a or the guide member 36b forming the ring holding portion 37b is formed on the outer peripheral portion. A circumferential groove into which a protrusion or an edge (not shown) of the portion is fitted is formed. The oblong major axis 42a of the inner hole 42 extends in a direction intersecting the axis 13 of the large-diameter rod 12 and the major axis of the guide ring 40 and the major axis of the fishing line introducing hole 12c are in the same plane. Be placed. Further, the ring holding portion 37b for holding the guide ring 40 is directed in the direction of releasing the fishing line from the fishing reel in a direction away from the large diameter rod 12 toward the rear of the large diameter rod 12. .

  The guide ring 40 is held in a state of protruding rearward from the ring holding portion 37b of the fishing line guide 36 over the entire circumference. As a result, the fishing line fed from the fishing reel is guided by the oval guide ring 40 having a small sliding resistance, and is guided from the guide member 36b of the fishing line guide 36 into the large-diameter rod 12 through the fishing line introduction hole 12c. Led to. For this reason, the introduction resistance of the fishing line is extremely small, and the entanglement hardly occurs.

  In the guide ring 40 of the present embodiment, the length of the short shaft 42b of the inner hole 42 is about 7 mm and the length of the long shaft 42a is larger than the large diameter rod 12 having an outer diameter of 16 mm to 21 mm of the attachment portion of the fishing line guide 36. The length of the long shaft 42a is longer than the length of the short shaft 42b in order to form the length of about 15 mm, improve the balance with the outer diameter of the large-diameter rod 12 and perform threading smoothly. It is preferable that the length is twice or more. Further, when this guide ring 40 is attached to the ring holding portion 37b of the fishing line guide 36, a distal point 42c that intersects the inner surface of the inner hole 42 farthest from the large-diameter rod 12 on the long axis 42a is large. The distance from the surface of the radial tube 12 is formed in the range of 20 mm to 30 mm. Thus, by separating the position of the distal point of the inner hole 42 from the large-diameter rod 12, the fishing line fed from the fishing reel does not easily hit the outer surface of the rod, and resistance due to contact with the rod is reduced. Can be reduced.

  The oval guide ring 40 has a proximal point 42d where the major axis 42a intersects the inner surface of the inner hole 42 at a position closest to the large-diameter rod 12 and is in contact with the inner side of the front ring member 34a. The large diameter rod through the fishing line introduction hole 12c from the common tangent line 44 that contacts the outside of the ring member 34b on the side, and the fishing line introduction hole 12c at the opening end of the plug body 26 of the fourth rod pipe 20 that is the former rod pipe It is arranged within the range of angles formed by respective extension lines with the rear side tangent line 46 extending outside the tube 12 and in contact with the rear side ring member 34b. As a result, the guide side tangent line 50 that contacts the proximal point 42d of the guide ring 40 and the rear ring member 34b is disposed between the common tangent line 44 and the rear side tangent line 46, and the It forms a very small angle with respect to it.

  On the other hand, the distal point 42c of the guide ring 40 extends to the outside of the large-diameter rod 12 through the fishing line introduction hole 12c from the rear tangent line 46 and a portion facing the fishing line introduction hole 12c at the opening end of the plug 26. It arrange | positions in the range of the angle which each extension line | wire with the front side tangent 48 which touches the side ring member 34a forms.

  By arranging the guide ring 40 in this way, when inserting a threading tool to be described later, the guide ring 40 is in contact with two points of the distal point 42c of the guide ring 40 and the front ring member 34a, and the guide ring. As long as it is within the range where the proximal point 42d of the 40 and the rear ring member 34b are in contact with each other, the end of the threading tool is not brought into contact with the inner surface of the large-diameter rod 12 and the plug body 26 can be inserted directly into the open end.

  In this embodiment, the axial length of the fishing line introduction hole 12c (specifically, the length between the ring members 34a and 34b) is formed to be 35 mm to 40 mm, and the fourth rod pipe 20 is joined as shown in FIG. The plug body 26 is disposed at a position of 40 to 80 mm from the fishing line introduction hole 12c when locked at the joint portion P4, and the diameter of the opening end of the plug body 26 is formed to be 10 mm to 14 mm. Thereby, the common tangent 44 forms an angle α1 of about 4 °, the rear tangent 46 forms an angle of about 13 °, and the front tangent 48 forms about 19 ° with respect to the axis 13 of the large-diameter soot tube 12. The angle α3 is formed. The guide side tangent 50 is preferably arranged in the range of 4 ° to 13 °, and the inner hole 42 of the guide ring 40 is arranged in the range of 4 ° to 19 °. When the position of the proximal point 42d is arranged at a position deviated from the range formed by the angles α1 and α2, the insertion path for inserting the threader is bent. In this case, insertion resistance acts on the threader.

  FIG. 4 shows various threading tools suitable for inserting from the fishing line introducing portion 24 and threading the threading rod 10.

  A threading device 60 shown in FIG. 4A has an elongated rod-like main body portion 64 integrally formed with a tapered tip end portion 62, and a loop-like thread hook portion 66 is formed at the rear end thereof. It is fixed via a tube 68. The threading tool 60 is generally formed of a metal material such as a superelastic alloy having 5 to 8% and an elongation of 3% or more. That is, it is preferable to form a material that deforms with an elongation of about 3% or more when a load is applied in the longitudinal direction and recovers with a recovery rate of about 90% or more when the load is removed. For example, it can be formed of a Ni-Ti alloy, a Ni-Ti-Fe alloy, a Ni-Ti-Cu alloy, or a Ni-Ti-Cr alloy.

  The threader 60 is preferably about 1.6 mm in diameter, 450 mm in length, and 5 g or more in weight.

  In the threading tool 60A shown in FIG. 4B, the main body portion 64A is formed of a closely wound coil spring, and the thread hook portion 66 is integrally formed of the same wire material as the main body portion 64A. Further, in the threading device 60B shown in FIG. 4C, the yarn hooking portion 66A has an acute-angled tip toward the rear end side, and is formed in a form like an automatic Harris stopper.

  In any of the threading tools 60, 60A, 60B, the outer diameters of the main body portions 64, 64A, 64B are formed larger than the inner diameter of the insertion tube 30 of the fishing rod protection cover 28. On the contrary, the inner diameter of the insertion tube 30 may be formed larger than the outer diameter of the threading tools 60, 60A, 60B.

  FIG. 5 shows a state in which such a threader is used to thread the threading rod 10.

  First, the penetrating fishing rod 10 is turned upside down and the fishing line guide 36 is arranged on the upper side. Next, the tip of the fishing line fed out from the fishing reel is attached to, for example, the thread hook 66 of the threading device 60 and brought into contact with the proximal point 42d of the guide ring 40 and the rear ring member 34b. Is inserted into the fishing line introduction hole 12c. In this state, the threading tool 60 can abut the distal end portion 62 against the opening end of the plug body 26 of the fourth heel tube 20 without bending the intermediate portion.

  The open end of the plug body 26 has a mortar shape that is reduced in diameter toward the fishing line insertion hole 26a from the rear end portion having the same diameter as that of the inner surface of the large-diameter rod 12 so that the threading device 60 is connected to the plug body 26. When the tip of the penetrating fishing rod 10 is directed downward in the state where it is in contact with the open end, the threading tool 60 falls by its own weight toward the tip of the first rod tube 14. In addition, when it does not fall by its own weight, it can be moved up and down or moved forward by centrifugal force.

  When the inner diameter of the insertion tube 30 is smaller than the outer diameter of the main body portion 64, the distal end portion 62 of the threader 60 is fitted into the insertion tube 30 of the fishing rod protection cover 28. On the contrary, when the inner diameter of the insertion tube 30 is larger than the outer diameter of the threading tool 60, the insertion tube 30 passes through the insertion tube 30 and protrudes outward from the tip of the fishing rod protection cover 28. In either case, the fishing rod protective cover 28 is removed and the threading tool 60 is removed from the insertion tube 30, or the threading device 60 pulled out from the fishing rod protective cover 28 is pulled and the fishing line fed out from the fishing reel. Is pulled out from the top guide 14 a of the first soot tube 14. Since the guide ring 40 held by the fishing line guide 36 protrudes rearward from the ring holding portion 37b, the threading tool 60 can be smoothly slid, and the insertion resistance to the fishing line is small.

  Such threading is the same when the threading tools 60A and 60B shown in FIGS. 4B and 4C are used, but the threading tools 60A and 60B are deformed by the main body portions 64A and 64B. Since it can be easily bent and smoothly bent after being inserted from the fishing line guide 36 into the narrow first rod 14, it can be easily inserted by following the angle change of these insertion paths. Can do.

  In the through rod 10 thus formed, the proximal point 42d of the inner surface of the guide ring 40 closest to the large diameter rod 12 is in contact with the inner side of the front ring member 34a and the rear ring member 34b. And a rear tangent 46 that extends from a portion facing the fishing line insertion hole 26a at the opening end of the plug body 26 of the tip 4 on the tip side and contacts the outside of the rear ring member 34b. When the fishing line is threaded from the guide ring 40, the gap between the guide ring 40 and the fishing line insertion hole 26a is linear and bent. Therefore, there is almost no insertion resistance, and the threading tools 60, 60A, 60B can be inserted very easily.

  The distal point 42c of the inner surface farthest from the large-diameter soot tube 12 is 20 mm to 30 mm from the outer surface of the large-diameter soot tube 12 within the range of angles formed by the respective extensions of the rear tangent 46 and the front tangent 48. By inserting the threading tools 60, 60A, 60B smoothly at the two points of the front or rear ring members 34a, 34b and the guide ring 40, the threading tools 60, 60A, 60B are smoothly inserted. Can do. If the distal point 42c is located near the large-diameter rod 12 than 20 mm, the convergence of the fishing line is poor and the fishing line insertion resistance is increased, and if it is located farther than 30 mm, the balance is poor and the weight is heavy. .

  Further, since the guide ring 40 protrudes rearward from the ring holding portion 37b over the entire circumference, the fishing line does not come into contact with the ring holding portion 37b in any case during threading or during actual fishing. It is guided smoothly while coming into contact with 40.

  Further, since the guide ring 40 has an oval shape, the proximal point 42d on the inner surface of the guide ring 40 closest to the large-diameter rod 12 is brought close to the large-diameter rod 12, while the distal point 42c on the opposite side is located. By separating from the large-diameter rod 12, it is possible to improve the insertion of the threader and reduce the resistance acting on the fishing line. That is, when the proximal point 42d of the guide ring 40 is disposed at a position separated from the outer surface of the large-diameter lance tube 12, an insertion path formed between the guide ring 40 and the plug body 26 during threading. Will be bent. Therefore, the threading tool 60 becomes a resistance and is not smoothly inserted into the first rod 14.

  The fishing line introduction portion 24 in the above-described through-hole fishing rod 10 is inclined with respect to the large-diameter rod tube 12 by forming the guide ring 40 in an oval shape so that the proximal point 42d of the guide ring is as close as possible to the large-diameter rod tube 12. The angle is reduced to improve the threadability of the threader 60, and the resistance given to the fishing line fed from the fishing reel with the distal point 42c of the guide ring 40 as far away from the large-diameter rod 12 as possible. And satisfying the mutually contradictory requirements of facilitating threading and reducing fishing line resistance. In addition, there is no inconvenience such as an increase in the amount of protrusion and an increase in weight due to an increase in size with a wide structure as in the case where the guide ring 40 is increased in diameter.
