Definitions

  • the present invention relates to a fishing rod having a solid rod shaft, and more particularly to a fishing rod characterized by a joint structure (joint structure) between adjacent large and small rod shafts.
  • a fishing rod with a solid structure (also called a "solid structure”) is known that is made up of a single solid rod shaft.
  • the rod shaft is provided with a reel seat for mounting a reel at the base end, and has multiple fishing line guides attached along the axial direction. If such a fishing rod with a solid structure is constructed as a single rod, its storage dimensions become long and it is difficult to handle, so it is known that the rod is made up of multiple solid rods, and a joint structure is provided at the end of each solid rod to join them in the axial direction (for example, Patent Document 1).
  • Patent Document 1 discloses a joint structure that enables solid rods to be joined
  • Figure 2 of the document discloses a joint structure in which a joint pipe (joint pipe body) exposed on the surface is disposed at the joint portion.
  • the inner peripheral surface at the tip end of the joint pipe body and the outer peripheral surface at the rear end of the front solid rod are fixed with adhesive, and the solid rods are joined together by inserting the tip end of the rear solid rod into the inner peripheral surface at the rear end of the joint pipe body.
  • the outer circumferential surface of the end of the solid rod is formed by applying adhesive to the outer circumferential surface of the end of the solid rod, and moving the inner surface of one end of the joint pipe and the solid rod relatively in the axial direction.
  • the inner diameter of the joint pipe is slightly larger than the outer diameter of the end of the solid rod, so when the solid rod is inserted into the inner surface of the joint pipe during bonding and fixing, the applied adhesive will overflow to the outside. In this case, the adhesive that has protruded to the outside can be wiped off, but the adhesive that has protruded to the inside cannot be wiped off, and if it hardens, it can cause abnormal noises and poor joints.
  • the present invention was made with a focus on the above-mentioned problems, and aims to provide a fishing rod with a joint structure between solid rod members that does not produce abnormal noise or poor joints at the joints.
  • the present invention provides a fishing rod having a large diameter solid rod and a small diameter solid rod joined in the axial direction, and a joint that joins the two solid rods together, the joint having a tubular joint body that covers the ends of the adjacent solid rods, and into which the outer surface of the end of one solid rod is adhesively fixed to one end side and the end of the other solid rod is press-fitted removably to the other end side, and the outer surface of the end of one solid rod is adhesively fixed to one end side of the joint body so that the gap width between the inner surface of the opening end of one end side of the joint body and the outer surface of the end of one solid rod is 0.05 to 0.25 mm when the edge of one solid rod is in contact with the inner surface of the joint body.
  • the outer surface of the end of one solid rod is adhesively fixed to the inner surface of one end of the joint tube.
  • the edge of the end of one solid rod comes into contact with the inner surface of the joint tube and stops. Therefore, when adhesive is applied to the outer surface of the end of one solid rod and the end of one solid rod is inserted into the inner surface of the joint tube, the applied adhesive does not leak inside. In other words, a fishing rod that does not produce abnormal noise or poor joints at the joint is obtained.
  • the present invention provides a fishing rod with a joint structure between solid rod rods that does not produce abnormal noise or poor joints at the joints.

  • FIG. 2 is a diagram showing a joint portion of the fishing rod shown in FIG. 1 .

  • FIG. 13 is a diagram showing the state in which the end of the solid rod is adhesively fixed to the joint pipe.
  • 1A to 1C are diagrams showing examples of the configuration of grooves formed on the outer surface (gently tapered surface) of the end of a solid rod.
  • FIG. 13 is a schematic diagram showing an example of attaching a fishing line guide to a joint pipe.
  • FIG. 1 is a diagram showing an embodiment of a fishing rod according to the present invention.
  • the fishing rod 1 according to this embodiment has a structure in which two solid rods are joined together, and includes a butt rod 3 and a tip rod 5, which are constructed as solid rods.
  • the butt rod 3 and the tip rod 5 have substantially the same axial length, and are constructed so that the two joint rods have a long overall length and can be carried compactly.
  • the tip end 3A of the butt rod 3 and the base end 5A of the tip rod 5 can be joined together by a joint 10, which will be described later.
  • the configuration may include three or more solid rods joined by joints 10. Furthermore, in such a configuration having multiple joints, it is sufficient that at least one joint 10, as described below, is provided.
  • the butt rod 3 and the tip rod 5 can be formed of, for example, a solid body made of fiber-reinforced resin, and there is no limitation on the material of the structure as long as it is a solid structure. Also, as long as the joint 10 is structured to join the solid parts, the other parts may have tubular parts.
  • the butt rod 3 is provided with a reel seat 6A on which a reel (not shown) is attached, a trigger 6B for hooking a finger, and a grip 6C.
  • the butt rod 3 and the tip rod 5 are provided with a plurality of known fishing line guides 30 arranged at regular intervals in the axial direction to guide the fishing line from the reel attached to the reel seat 6A.
  • FIGS. 2 is a diagram showing an example of a joint 10 between adjacent butt rods 3 and tip rods 5.
  • the tip end 3A of the butt rod 3 and the base end 5A of the tip rod 5 are joined to form a tapered fishing rod, so that the butt rod 3 is a large-diameter solid rod and the tip rod 5 is a small-diameter solid rod (hereinafter also referred to as the large-diameter solid rod 3 and the small-diameter solid rod 5).
  • the joint 10 has a tubular joint body 11 that covers the ends of the adjacent solid rods (the tip 3A of the large diameter solid rod 3 and the base 5A of the small diameter solid rod 5).
  • the outer surface 3a of the tip 3A of the large diameter solid rod 3 is adhesively fixed to one end 11A of this joint body 11, and the base 5A of the small diameter solid rod 5 is press-fitted and fixed so as to be insertable and removable to the other end 11B.
  • the one end side 11A of the joint pipe 11 is shaped to gradually expand in diameter toward the large diameter solid rod 3 (rear end side).
  • the inner surface 11a of the one end side 11A of the joint pipe 11 in this embodiment has a tapered surface (a steeply tapered surface when compared to the tip 3A of the large diameter solid rod 3), and the outer surface 3a of the tip 3A of the large diameter solid rod 3 has a more gradual tapered surface (a gently tapered surface).
  • it is sufficient that the taper of the inner surface 11a of the joint pipe 11 and the large diameter solid rod 3 is greater than the taper of the outer surface 3a.
  • adhesive 20 is applied to the outer surface (also called the gently tapered surface) 3a of the tip 3A of the large-diameter solid rod 3, and the tip is inserted into the inner surface (also called the steeply tapered surface) 11a of the joint pipe 11, so that the outer surface 3a of the tip 3A of the large-diameter solid rod 3 is glued and fixed to one end 11A of the joint pipe 11, as shown in FIG. 2.
  • the outer surface 3a of the inserting side has a gentler taper than the inner surface 11a of the inserted side, so that when the large-diameter solid rod 3 is inserted, the end edge 3b of the tip 3A hits the inner surface 11a and stops (see FIGS. 3 and 2; P is the stopping position).
  • a gap G is formed that gradually expands in diameter from the end edge 3b toward the base end.
  • the gap width G1 between the inner surface 11a at the opening end 11a' on one end side of the joint pipe 11 and the outer surface 3a of the end of the large diameter solid rod 3 is the widest at the position of the opening end 11a' of the large diameter solid rod. It is preferable that the outer surface 3a of the large diameter solid rod 3 is adhesively fixed to one end side of the joint pipe 11 so that this gap width G1 is 0.05 to 0.25 mm, preferably 0.10 to 0.20 mm.
  • the adhesive 20 applied to the outer surface 3a of the tip 3A of the large-diameter solid rod 3 is pushed out toward the base end of the large-diameter solid rod 3 and may flow out along the outer surface 3a of the tip 3A as shown by the arrow D in Fig. 4.
  • the adhesive 20 applied to the outer surface 3a of the tip 3A does not leak inside as shown by the arrow D1 because the edge 3b hits the inner surface 11a.
  • the adhesive 20 flows out along the outer surface 3a of the end of the large-diameter solid rod 3, the flowing adhesive can be wiped off. In this manner, the gradually expanding gap G and the adhesive 20 filled in the gap G reduce the contact of the edge 11a' portion with the outer surface 3a, making it possible to suppress cracking.
  • the adhesive may not be sufficiently filled, resulting in poor adhesion.
  • the adhesive may also not spread straight, causing poor adhesion.
  • the end edge 3b may squeeze the large diameter solid rod when it is inserted, causing a shortage of adhesive and resulting in poor adhesion.
  • the difference between the two tapers should be set in the range of 1/1000 to 3/1000.
  • the adhesive length L between the steeply tapered surface 11a and the gently tapered surface 3a is short, the adhesive strength in the joint 10 area will be weak, and the adhesive strength may decrease when the fishing rod is bent. Furthermore, if the adhesive length L is long, it may affect flexibility or increase weight. For this reason, it is preferable to set the adhesive length L in the range of 30 to 100 mm.
  • the gap width G1 is 0.05 to 0.25 mm, but if the mating length L is made longer at 100 mm, it is possible to keep the gap width G1 in the range of 0.10 to 0.20 mm by configuring the taper difference to be 1/1000 to 2/1000. Also, if the mating length L is made shorter at 30 mm, it is possible to keep the gap width G1 at 0.09 mm (within the range of 0.05 to 0.25 mm) by setting the taper difference to about 3/1000.
  • the taper (steep taper surface) of the inner surface 11a of the joint pipe body 11 is set to 4/1000, and the taper (gentle taper surface) of the outer surface 3a of the large diameter solid rod 3 is set to 3/1000, with the taper difference being set to 1/1000.
  • the other end 11B of the joint pipe 11 constituting the joint portion 10 is press-fitted so that the base end 5A of the small diameter solid rod 5 can be inserted and removed.
  • This press-fitting is achieved by a tapered structure.
  • the other end 11B of the joint pipe 11 is straight, and is configured to fit into the tapered surface formed on the base end 5A of the small diameter solid rod 5.
  • the end side of the base end 5A has a straight outer peripheral surface 5a with a diameter slightly smaller than the diameter of the inner surface of the other end side 11B of the joining pipe 11, and this portion forms a parallel joint structure (parallel joint length L1).
  • the outer peripheral surface 5a has a tapered surface 5b that gradually expands in diameter from the middle toward the tip side. Therefore, when the base end 5A of the small diameter solid rod 5 is inserted into the opening of the other end side 11B of the joining pipe 11, the outer peripheral surface 5a slides against the inner surface 11b of the other end side 11B of the joining pipe 11, and finally the tapered surface 5b abuts against the open end 11d of the other end side 11B of the joining pipe 11 to form a joined state.
  • the parallel joint length L1 is set in the range of 30 to 100 mm.
  • an axial gap S is formed inside the joint pipe body 11 between the large diameter solid rod 3 and the small diameter solid rod 5 (more specifically, between the end edge 3b of the large diameter solid rod 3 and the end edge 5c of the small diameter solid rod 5).
  • this gap S With regard to the axial length L2 of this gap S, if it is made too long, it will reduce strength and affect bending of the rod (it will bend too much), whereas if it is made too short, it will cause alignment problems due to variations in the adhesive length (the end edge 5c of the small diameter solid rod 5 and the end edge 3b of the large diameter solid rod 3 will come into contact), so it is preferable to set it in the range of 10 to 40 mm.

  • a spiral groove 27 may be formed.
  • such a recess By forming such a recess, the anchor effect of the adhesive is increased, and the adhesive strength can be improved.
