Description

  The present invention includes a first tip portion having a solid structure and a second tip portion formed in a tubular structure, and protrudes rearward from the first tip portion into a fitting hole opened at the tip of the second tip portion. The present invention relates to a fishing rod having a rod formed by fitting a fitting portion and joining a first tip portion and a second tip portion into an integrated structure.

  In general, fishing rods that are formed in a long length by connecting multiple rods have a tip rod that is formed in a thin and lightweight structure at the tip. Can be perceived sensitively, and due to its flexibility, it can be bent greatly to follow the movement of the fish.

The tip of such a fishing rod has a solid structure on the front side, and a small-diameter insertion portion that protrudes backward from the front side is fitted into the front opening of the rear side formed in a hollow structure. However, there is an adhesive in which the front side portion and the rear side portion are integrally coupled via the insertion portion and the opening portion (see, for example, Patent Document 1).
JP-A-8-332002

  FIG. 6 shows a normal operation process for forming a spear having such a joint structure.

  As shown in FIGS. 6A to 6C, the front side portion 1 formed of a solid body projects a small-diameter fitting portion 1b from the rear end side through a tapered surface 1a and is formed of a hollow body. A similar tapered surface 2 a is formed at the opening end of the side portion 2. As shown in (B) of the figure, an adhesive S is applied to the fitting part 1b and the tapered surface 1a and inserted into the inner hole 2b of the rear side part 2, as shown in (C) of the figure. In addition, after holding until the adhesive S is cured, the bonding between the front side portion 1 and the rear side portion 2 is completed. As a result, a single tipper having a joint structure is completed. The tapered surfaces 1a and 2a prevent a step from being formed at the joint and smooth the change in rigidity.

  However, when the insertion portion 1 b having the adhesive S applied to the outer peripheral portion is inserted into the inner hole 2 b of the rear side portion 2, the adhesive S is squeezed by the rear side portion 2. When the adhesive S is cured in this state, the central axes of the front side portion 1 and the rear side portion 2 are fixed in an inclined state by the thickness of the adhesive S.

  As shown in FIG. 7 in a state where the adhesive S is inclined and fixed by the thickness of the adhesive S, the portion where the thickness of the adhesive S is thin is insufficient in adhesive strength. In this case, when the front side portion 1 is greatly bent, peeling may occur due to insufficient adhesive force. Moreover, when the center axis line of the front side part 1 and the rear side part 2 inclines mutually, it will be in the state bent in the intermediate part of the tip of a tip, and the case where it is difficult to perform fishing operation smoothly may arise.

  The present invention has been made based on such circumstances, and the first tip portion having a solid structure and the second tip portion having a tubular structure are joined to each other with a stable adhesive strength while securing a stable adhesive layer. An object is to provide a fishing rod having a combined rod.

  The fishing rod of the present invention that achieves the above object includes a first tip portion having a solid structure and a second tip portion formed in a tubular structure, and the fitting hole that opens at the tip of the second tip portion includes the first tip portion. A fishing rod having a rod formed by fitting a fitting portion projecting backward from one tip portion and joining the first tip portion and the second tip portion into an integrated structure, A bulging portion that directly contacts the inner peripheral surface of the fitting hole and an adhesive portion that forms an adhesive layer between the inner peripheral surface and the inner peripheral surface are formed.

  The bulging portion may be formed at a plurality of positions spaced in the axial direction.

  In addition, the bulging portion can be formed as a separate member from the first tip portion.

  According to the fishing rod of the present invention, the bulging portion formed in the fitting portion of the first tip portion comes into contact with the inner peripheral surface of the fitting hole of the second tip portion. An adhesive layer having a required thickness is formed on the peripheral surface without squeezing the adhesive between the inner peripheral surface of the joint hole, and thereby, the first tip portion of the solid structure and the tubular structure are formed. A fishing rod having a rod that joins the second tip portion with a stable attachment strength while securing a stable adhesive layer is provided.

  When this bulging part is formed at a plurality of positions at intervals in the axial direction, an adhesive layer having a uniform thickness is formed between the inner peripheral surface of the fitting hole and the outer peripheral surface of the adhesive part. can do.

  Moreover, it can be set as a suitable material or magnitude | size according to a 2nd tip part by forming a bulging part with a 1st tip part and another member.

  FIG. 1 shows a fishing rod 10 according to a preferred embodiment of the present invention.

  The fishing rod 10 is formed as a swing-out type rod, for example, and a reel sheet 14 is provided on the largest-side rod 12 capable of sequentially storing a plurality of rods on the tip side. A fishing reel 8 is attached. A fishing line guide 6 for preventing the fishing line from adhering to the outer surface of the rod is fixed to the fishing rod 10 on the same side as the fishing reel 8 at a predetermined interval toward the tip of the fishing rod 10. A top guide 6a is attached to the tip. The number and arrangement position of such fishing line guides 6 are not limited to the illustrated example, and can be arbitrarily set.

  Such a fishing rod 10 is not limited to a swing-out type, and may be of an appropriate joint type such as a brazing joint, a parallel joint or a reverse parallel joint. Moreover, you may form not only from several wrinkles but only with one wrinkle.

  The tip 16 arranged at the foremost end of the fishing rod 10 is formed by a rod in which a solid first structure and a second structure formed in a tubular structure are joined together. A top guide 6a is fixed to the tip of one tip. By forming the first tip portion on the tip side of the tip rod 16 in a solid structure, it can be greatly bent by pulling fish or the like, and a fine fish belief can be transmitted through a fishing line.

  As shown in an enlarged view in FIG. 2, the hook forming the tip hook 16 of the present embodiment has a solid structure of the first tip part 20 and the second tip part 30 formed in a tubular structure in an integrated structure. They are formed together. The second tip portion 30 is formed through a normal process such as curing and decentering after a fiber reinforced prepreg (FRP) sheet in which a reinforcing fiber is impregnated with a synthetic resin is wound around a cored bar. Moreover, the 1st tip part 20 of a solid structure may be formed with the solid body formed with the suitable single material, or the structure which formed the fiber reinforced resin layer in the peripheral part of the solid body. In addition, it replaces with fiber reinforced resin and the 1st tip part 20 can also form the whole or one part with appropriate metal materials, such as a superelastic alloy, for example.

  The first tip portion 20 includes a main body portion 22 that forms the outer peripheral surface of the tip tip 16 together with the second tip portion 30, and a fitting portion 24 that protrudes rearward from the rear end on the original side of the main body portion 22. Have. Moreover, the 2nd tip part 30 has the inner hole 32 penetrated to an axial direction, and the fitting hole 34 with which the fitting part 24 of the 1st tip part 20 fits is opened and formed in the front end side.

  The fitting hole 34 that opens at the tip of the second tip 30 has a tapered portion 34a that expands toward the tip, and a cylindrical portion 34b that continues to the rear end of the tapered portion 34a. The cylindrical portion 34b is formed by a part of the inner hole 32, that is, the same diameter and a continuous inner peripheral surface. The tapered portion 34a can be formed with an appropriate inclination angle, but prevents a large step from being formed between the outer peripheral surface of the main body portion 22 of the first tip 20 and gradually changes the rigidity. Therefore, it is preferable to form the taper at an angle of about 20 to 80/1000 with respect to the central axis.

  On the other hand, the fitting portion 24 of the first tip portion 20 includes a tapered portion 24a that decreases in diameter from the cylindrical main body portion 22 toward the rear, and a cylindrical portion 24b that extends rearward from the rear end of the tapered portion 24a. And a bulging portion 24c disposed at the rear end of the cylindrical portion 24b. The tapered portion 24 a is formed at substantially the same inclination angle as the tapered portion 34 a located on the distal end side of the fitting hole 34, and the cylindrical portion 24 b is slightly more than the inner peripheral surface of the cylindrical portion 34 b of the fitting hole 32. The bulging portion 24c is formed to have a small diameter and the same diameter as the inner peripheral surface of the cylindrical portion 34b. The cylindrical portion 24b has an inner diameter in the range of 0.05 to 0.3 mm, preferably about 0.10 mm, smaller than the inner peripheral surface of the cylindrical portion 34b of the fitting hole 34. The cylindrical portion 34b An annular space for forming the adhesive layer 40 is formed between the inner circumferential surface and the inner circumferential surface. By forming the outer diameter of the cylindrical portion 24b in this way, the depth of the fitting portion 24 inserted into the fitting hole 34 is adjusted, and the tapered surface 24a of the fitting portion 24 and the taper of the fitting hole 34 are adjusted. An adhesive layer 40 having a similar thickness can be formed between the surface 34a.

  When integrally joining the first tip portion 20 and the second tip portion 30 thus formed, it is suitable for the outer periphery of the tapered portion 24a and the cylindrical portion 24b of the fitting portion 24 of the first tip portion 20. Apply adhesive. This adhesive is formed on the cylindrical portion 24b so as to have a thickness at least equal to the outer peripheral surface of the bulging portion 24c.

  Thereafter, the fitting portion 24 of the insertion portion 20 is inserted into the fitting hole 34 of the second tip portion 30 from the bulging portion 24 c located at the rear end, that is, the rear end of the fitting portion 24. The bulging portion 24 c is guided to the cylindrical portion 34 b by the tapered portion 34 a located at the tip of the fitting hole 30. Further, when the first tip portion 20 is pressed rearward, the bulging portion 24c is pushed backward while being guided along the inner peripheral surface of the cylindrical portion 34b, and the outer periphery of the cylindrical portion 24b of the fitting portion 24 is pushed. Is secured between the inner peripheral surface of the cylindrical portion 34b of the fitting hole 34 and having a certain radial dimension over the entire circumference. The adhesive applied to the outer peripheral portion of the cylindrical portion 24b is squeezed off at the distal end side of the cylindrical portion 34b of the fitting hole 34, thereby preventing uneven thickness along the circumferential direction.

  And by hold | maintaining in the state in which the cyclic | annular gap | interval 35 of required width was formed between the rear end of the main-body part 22 of the 1st tip part 20, and the front-end | tip of the 2nd tip part 30, between taper part 24a, 34a In addition, a gap similar to that between the cylindrical portions 24b and 34b is formed, and the adhesive layer 40 having a uniform thickness is formed over the entire circumference. By curing the adhesive layer 40, the tip ridge 16 composed of a single heel joined to the integrated structure with a fixed mounting strength is formed.

  In the present embodiment, the fitting portion 24 of the first tip portion 20 functions as an adhesive portion in which the tapered portion 24a and the cylindrical portion 24b are bonded and fixed to the second tip portion 30 via the adhesive layer 40, Further, the bulging portion 24 c functions as a guide portion that guides the outer circumferential side of the cylindrical portion 24 b along the inner circumferential surface of the fitting hole 34 while ensuring a certain gap. In order to exhibit the function as the guide portion, it is preferable that the length in the axial direction of the bulging portion 24 c is, for example, about 0.5 to 20% with respect to the length of the fitting portion 24.

  Therefore, according to the above-described embodiment, the bulging portion 24 c formed in the fitting portion 24 of the first tip portion 20 contacts the inner peripheral surface of the cylindrical portion 34 c of the fitting hole 34 of the second tip portion 30. As a result, the taper portion 24a and the cylindrical portion 24b, which are the bonding portions of the fitting portion 24, and the taper portion 34a and the inner peripheral surface of the cylindrical portion 34b of the fitting hole 34 are bonded to each other with a required thickness. The agent layer 40 has a substantially constant thickness over the entire circumference thereof, thereby securing the stable adhesive layer 40 between the first tip part 20 having a solid structure and the second tip part 30 having a tubular structure. There is provided a fishing rod 10 having a tip rod 16 formed of rods spliced together with stable mounting strength.

  FIG. 3 shows a tip 16A according to another embodiment. Since various embodiments or modifications shown below are basically the same as those in the above-described embodiment, similar members are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the embodiment shown in FIG. 3, the bulging portion 24c is formed at two positions spaced apart in the axial direction between the rear end and the front end of the cylindrical portion 24b.

  In this case, in addition to the same effects as those of the above-described embodiment, when the fitting portion 24 is inserted into the fitting hole 34, the fitting portion 24 can be prevented from tilting, and the cylindrical portion can be prevented. An annular gap having a constant radial dimension is secured between 24b and 34b, and the inclination of the center axis of the first tip 20 with respect to the center axis of the second tip 30 is prevented. Can be held on the same line. Such a bulging portion 24c is not limited to two positions, and may be three or more positions. In this case, the overall axial dimension of the bulging portion 24c can be shortened.

  In the embodiment shown in FIG. 4, the bulging portion 24 c formed in the fitting portion 24 of the tip 16 b is formed by a cap member 26 formed separately from the first tip 20.
