Description

  The present invention relates to a fishing rod, and in particular, to a fishing rod having a characteristic of a pointed rod.

  Conventionally, as a tip of a fishing rod, for example, as disclosed in Patent Document 1, it is known to use a solid core material (super elastic alloy). Since the spikelet made of such a superelastic alloy is difficult to break and has excellent flexibility, it has the advantage that it can be made smaller in diameter and can detect small fish.

In addition, the spikelet disclosed in Patent Document 1 has a straight portion in a range of 4 to 20 mm from the tip portion, and a top guide can be attached to the straight portion, and the taper portion is continuous with the straight portion. The fishing line guide is adhered and fixed to the portion.
JP 2006-6229 A

  The tip rod constructed as described above cannot be applied to a swing-out type fishing rod considering the closing dimensions because the fishing line guide is fixed. In addition, the tip rod having the above-described configuration has the following problems even if an idle guide is used as a fishing line guide.

  A fishing rod having a tip rod as described above may involve a mechanism during actual fishing, and the tip rod may bend greatly as compared to a normal bend. In such a state, when the floating guide is fixed to the steep taper portion, as shown in FIG. 4, the outer surface of the tip rod 50 and the inner surface of the pipe 61 of the floating guide 60 are not in surface contact but in a point contact state. Or it will be in a line contact state and the problem that the fixing force of the floating guide 60 will fall and loosen will arise.

  In addition, in the above-described configuration, since the fishing line guide is mounted on the steep taper portion, there is a problem that it is difficult to obtain a delicate fish sensitivity because it is impossible to obtain a smooth change in rigidity on the tip side of the tip. Arise.

  The present invention has been made based on the above-described problem, and an object of the present invention is to provide a fishing rod provided with a tip rod that can be easily loosened and can be smoothly changed in rigidity.

  In order to achieve the above-described object, a fishing rod according to the present invention has a solid core material, and has a tip rod equipped with a floating guide for inserting a fishing line through the core material. The core material includes a straight portion formed on the distal end side, a taper portion formed on the proximal end side of the straight portion, and a taper formed on the proximal end side of the taper portion, which is looser than the taper of the taper portion. And a loosely tapered portion, wherein the loose guide portion is fixed at a position where the floating guide is fixed.

  According to the fishing rod having the above-described configuration, for example, when the tip rod is bent by winding the device, the most bent portion (bending point) becomes the boundary region between the straight portion and the tapered portion. The loose guide is fixed on the loosely tapered portion formed on the proximal end side with respect to the tapered portion and is away from the bending point. The state of surface contact with the inner surface of the guide pipe is not significantly impaired. Therefore, the loose guide is prevented from loosening when the tip is greatly bent. In addition, since the floating guide is not fixed to the straight portion and the tapered portion of the tip end, the tip end of the tip end becomes a smooth change in rigidity, and the tone can be improved.

  According to the present invention, it is possible to obtain a fishing rod provided with a tip rod that makes it difficult for the floating guide to loosen and a smooth change in rigidity can be obtained.

  FIG. 1 to FIG. 3 are views showing an embodiment of a fishing rod according to the present invention, FIG. 1 is a diagram showing an overall configuration, FIG. 2 (a) is a diagram showing a configuration of a main part of a tip rod, and FIG. 2 (b) is a longitudinal cross-sectional view of the main part of the tipper, FIG. 3 (a) is a diagram showing a normal state of the tip, and FIG. 3 (b) is a case where the mechanism is involved. It is a figure which shows the state which bent greatly.

  The fishing rod 1 according to the present embodiment includes a base rod 3, a plurality of middle rods 5, and a tip rod 10. Each rod is joined by a swing-out type. In this case, there may be a configuration without the intermediate rib 5, or a large number of pieces may be joined as shown in FIG.

  The base rod 3 and the intermediate rod 5 are formed of a fiber reinforced resin tubular body. For example, fiber reinforcement obtained by impregnating a reinforcing fiber (mainly carbon fiber or glass fiber) with a synthetic resin such as an epoxy resin. A resin prepreg (prepreg sheet) is wound around a metal core, subjected to a heating step, and then decentered.

  Further, the fishing rod 1 is provided with a plurality of outer guides for guiding the fishing line from the reel R attached to the main rod 3, and at least one or more of the guide rods 10 are provided on the tip rod 10 as will be described later. A floating guide is installed.

  The tip 10 is provided with a solid core material 12, which is made of a superelastic alloy material (for example, Ni-Ti alloy, Fe-Al alloy, etc.). In this case, the tip 10 may be composed of only such a solid core material 12, or may be configured to include a tubular hollow body into which the core material 12 is inserted.

  The core material 12 is made of a superelastic alloy material, so that it is difficult to break even if a bending point as described later is provided to form a largely bent portion. Of course, the core material 12 may be a solid and columnar material. For example, the core material 12 may be made of a material such as a reinforced fiber resin formed by impregnating a synthetic resin such as an epoxy resin into glass fiber or carbon fiber. It may be formed.

  A top guide 15 for leading the fishing line is attached to the tip of the core member 12. Further, the surface shape of the core member 12 is formed so as to change along the axial length direction so that a bending point (a position where the curvature becomes maximum when bent) is generated at a predetermined position.

  Hereinafter, the configuration of the core material 12 will be specifically described.

  The core member 12 includes a changing portion 12A in which the surface state along the axial length direction changes so that a bending point is formed at a predetermined position from the distal end side. This changing portion 12A is a portion where the radius of curvature is the smallest (the curvature is the largest) when the core material 12 is bent, and in this embodiment, on the surface of the core material 12, the base end side in the axial length direction The changing portion 12 </ b> A is formed by providing a tapered portion that gradually increases in diameter as it shifts to.

  Specifically, a straight portion 12a is formed on the distal end side of the core member 12, and a tapered portion 12b is formed on the proximal end side of the straight portion 12a, and changes at the boundary portion between the straight portion 12a and the tapered portion 12b. A portion 12A is formed.

  In this case, the straight portion 12a may have a strict straight shape in which the outer diameter does not change along the axial length direction, or slightly increases in diameter as it moves to the base end side. Such a taper shape may be used. However, even such a tapered shape is formed more loosely than the taper of the tapered portion 12b.

  The taper of the taper portion 12b is not particularly limited, but it may be formed in the range of 2.50 / 1000 to 7.50 / 1000 in consideration of the tone of the spikelet and the like. The outer diameter of the portion 12A may be formed in the range of 0.40 to 0.80 mm.

  Further, the core member 12 is formed with a gentle taper portion 12c that is continuously tapered at a proximal end side of the taper portion 12b.

  By forming such a gentle taper portion 12c, the taper portion 12b prevents the tip region of the tip heel 10 from becoming thicker, and the weight can be reduced. It is possible to improve. Further, such a gentle taper portion 12c is a region to which the floating guide 20 (tip side floating guide) is fixed.

  The floating guide 20 includes a pipe 21 that is inserted into the core member 12, and by gripping this portion and sliding in the axial direction, the inner surface of the pipe 21 is the outer surface of the gently tapered portion 12c. Fixed in contact with the surface. For this reason, if the taper of the gentle taper portion 12c is too large or too small, a sufficient contact area with the inner peripheral surface of the pipe 21 is not ensured, and it becomes easy to loosen. It is preferably smaller than the taper of the taper portion 12b and in the range of 0.00 / 1000 to 0.50 / 1000. Further, the outer diameter of the base end portion 12B (the boundary between the tapered portion 12b and the following gently tapered portion 12c) is preferably formed in a range of 0.70 to 1.20 mm.

  If the straight portion 12a is too short, the changing portion 12A is too close to the tip to become a bending point, and the tip tone is also lowered. In addition, if the straight portion 12a is too long, the position where the maximum curvature is reached when the device is rolled can be moved to the tip side from the fixed position of the floating guide 20, but the tip portion of the tip is too soft. The balance as a fishing rod will decrease. For this reason, about the length of the straight-shaped part 12a, it is preferable to form in the range of 20-50 mm from a front-end | tip.

  The top guide 15 is fixed in a state where the top guide 15 is fitted into the tip of the straight portion 12a. Further, the floating guide 20 is preferably fixed at a position where the distance from the tip position of the scissors rod 10 to the end portion of the pipe 21 is about 100 mm in consideration of balance of balance, sensitivity, and the like.

  In addition to the above-described floating guide 20, a plurality of floating guides (a second floating guide 22 is shown in FIG. 3) may be disposed on the tip end 10 in addition to the above-described floating guide 20. .

  Next, the operation and effect of the fishing rod provided with the tip rod 10 configured as described above will be described.

  As described above, as shown in FIG. 3 (a), the core material 12 of the tip rod 10 is bent at a predetermined position from the tip side (changed portion 12A serving as a boundary between the straight portion 12a and the tapered portion 12b). have. When the change portion 12A is involved in the device, as shown in FIG. 3B, the change portion 12A is greatly bent with the change portion 12A serving as a bending point (a position where the curvature becomes maximum).

  However, as shown in FIG. 3B, the gentle taper portion 12c does not bend greatly, so the pipe 21 of the floating guide 20 fixed to the gentle taper portion 12c It is possible to effectively prevent a loose contact due to a decrease in the fixing force of the floating guide 20 due to a point contact state or a line contact state between the guide and the guide.

  Moreover, since the floating guide 20 is not fixed to the straight portion 12a or the tapered portion 12b, the rigidity change on the tip side of the tip rod 10 can be made smooth, and the fish faith sensitivity can be improved. It becomes possible.

  In addition, since the changing portion 12A serving as a bending point of bending is provided at the boundary portion between the straight portion 12a and the tapered portion 12b and the straight portion 12a is provided with a predetermined length, the straight portion has a small diameter. This makes it possible to obtain a fishing rod in which the tip of the tip easily reacts to a small fish bean.

  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, with respect to the tip 10, a fiber reinforced resin prepreg may be wound as necessary. In this case, it is preferable that the prepreg made of fiber reinforced resin to be wound is located on the base end side from the vicinity of the gentle taper 12c so that peeling or the like does not occur when the tip end is greatly bent.

  Also, the position where the floating guide 20 is fixed is not limited as long as it is on a gentle taper, but if it is too long, the distance from the top guide will be too wide and the tip will be too hot. Since the outer surface and the fishing line are likely to come into contact with each other, it is preferable that the outer surface is fixed within a range of 5 to 30 mm from the base end portion 12B.

It is a figure which shows one Embodiment of the fishing rod which concerns on this invention, and is a figure which shows the whole structure. (A) is a figure which shows the structure of the principal part of a harpoon, (b) is a longitudinal cross-sectional view of the principal part of a harpoon. (A) is a figure which shows the normal state of a pointed hook, (b) is a figure which shows the state in which the pointed hook is greatly bent, such as when a mechanism is involved. The figure which shows the state in which the tip collar with which the conventional idle guide was mounted | worn was bent.
