Description

  The present invention relates to a fishing rod, and more particularly to a fishing rod structure used for smelt fishing.

  Smelt fishing is a fishing that specializes in smelt fishing in the winter in the lake. The smelt is a small fish with a length of several cm to 15 cm and is relatively easy to fish, so smelt fishing is popular among anglers. However, fishing results greatly depend on the selection of the mechanism, food, and the operation of the mechanism (so-called “invitation”), and the technique for manipulating the mechanism (the “invitation” technique) is more important for advanced fish smelters. To do.

  FIG. 7 schematically shows a common smelt fishing device.

  In smelt fishing, a fishing rod 1 and a reel 2 are used, and a device 4 is connected to a line 3 wound around the reel 2. The device 4 includes a weight 5, and as shown in the figure, the device 4 is submerged to the vicinity of the lake bottom 6 by the action of the weight 5. The angler tilts the fishing rod 1 to the required angle θ and waits for the smelt to hit. This angle θ is set by the angler's feeling, so that the angler can accurately grasp that the fish has hit the fisherman (so-called “Atari”) and intentionally vibrate the tip 7 of the fishing rod 1. The angle is adjusted to make it easier to make an “invitation”. That is, in order for a fisherman to operate a device ("invite"), the elasticity and bending characteristics of the fishing rod 1 are extremely important, and various proposals and improvements have been made regarding fishing rods (for example, Patent Document 1). -Patent Document 4)

  The fisherman throws the device 4 into the water and then intentionally vibrates the tip 7 up and down from the state shown in FIG. The angler uses the following techniques to raise the results. That is, the angler intentionally gives a minute vibration to the tip 7 and senses the attack when the vibration changes irregularly and irregularly. Based on the experience of anglers, catching such minute changes in the vibration of the tip 7 greatly affects the fishing results in smelt fishing.

  Then, the performance required for the fishing rod 1 is that the tip 7 can cause fine and uniform vibration, in other words, the tip 7 is soft, and the fishing rod 1 bends smoothly and bends uniformly. To restore. In addition, the fisherman collects the device 4 using the reel 2, but the fishing rod 1 bends smoothly in order to prevent the smelt from falling out of the device 4 (so-called “barashi” does not occur). is important.

  Incidentally, the line guide 8 needs to be attached to the fishing rod 1 in order to support the line 3. The line guide 8 is generally fixed at a required position of the fishing rod 1 with a thread and an adhesive. On the other hand, since the tip 7 is formed softly, the rigidity of the tip 7 naturally decreases. Therefore, when the line guide 8 is attached to the fishing rod 1, the rigidity of the attachment portion is locally increased, and when the tip 7 vibrates or when the device 4 is collected, the fishing rod 1 is not bent uniformly, There is a risk that secondary vibration will occur with the attachment site as a node. As a result, there are inconveniences that the angler is less likely to make an “invitation” in actual fishing, difficult to catch, and moreover, the hit smelt is likely to come off the needle (easy to “break”).

  The present invention has been made based on such a background, and an object of the present invention is to provide a fishing rod and a fishing rod main body that can be bent smoothly and can be bent uniformly. That is.

(1) A fishing rod for smelt according to the present invention is made of resin or fiber reinforced resin, and includes a fishing rod main body having a base end portion and a grip for supporting the base end portion of the fishing rod main body. The belt has a strip-shaped portion that is continuous with the base end and has a flat cross-sectional shape, and a plurality of line guides are arranged in parallel along the longitudinal direction of the strip-shaped portion. Is provided with a predetermined taper from the base end side to the tip end side, and a defective portion is formed in the vicinity of the base end side near the base end side of the portion where the line guide is provided to reduce bending rigidity. The defect portion is formed by an arc-shaped cutout recess formed to face both side surfaces of the belt-like portion.

According to this configuration, since the fishing rod main body is made of resin or fiber reinforced resin , the fishing rod main body has a homogeneous structure. Therefore, if the above-mentioned defect portion does not exist, the section modulus of the fishing rod main body is from the proximal end portion to the distal end portion. When the bending moment is applied to the main body of the fishing rod, the entire body is smoothly curved and deformed. When the section modulus is set to be small, the fishing rod body reacts sensitively to a minute bending moment and is curved and deformed. However, since this fishing rod main body is provided with a plurality of line guides at predetermined intervals along the longitudinal direction, naturally the section modulus is locally increased at the site where the line guides are provided, When a bending moment acts on the fishing rod main body, the fishing rod main body tends to be unable to bend and deform smoothly.

In this invention, the said defect | deletion part is provided in the said fishing rod main body, and each defect | deletion part is located in the vicinity of the said line guide. More specifically, arc-shaped cutout recesses are formed on both side surfaces of the belt-like portion of the fishing rod main body so as to face each other. By providing the arc-shaped cutout concave portion in the band-like portion, the section modulus is locally and effectively reduced at the portion where the cutout concave portion is provided, and the rigidity of the fishing rod main body is locally reduced. That is, the increase in the section modulus due to the provision of the fishing line guide and the decrease in the section modulus due to the provision of the deficient portion are offset, and as a result, the section modulus of the fishing rod body gradually becomes smooth from the proximal end toward the distal end. The fishing rod body bends smoothly and bends evenly even when a small bending moment is applied. The above-mentioned conventional procedure is typically a fishing line guide fastened to an elongated rod-like body with nylon thread and fixed with an adhesive.

  According to the present invention, the small clam of smelt and other small fish can be reliably caught by the angler, and the fish can be prevented from dropping off from the fishhook.

[How to use fishing rod]

  In this fishing rod 10, since the fishing rod main body 11 is made of glass fiber reinforced resin, the fishing rod main body 11 is configured as an elongated rod-like body having a homogeneous structure. For this reason, in the site | part in which each said notch recessed part 16-20 was provided (refer FIG. 1), the section modulus of the fishing rod main body 11 becomes small, and rigidity has fallen locally. However, since the mounting leg 23 of the line guide 12 is fixed with the nylon thread 24 and an adhesive adjacent to the portion where the notch recesses 16 to 20 are provided, the cross section by the provision of the notch recesses 16 to 20. The decrease in the coefficient and the increase in the section modulus due to the fixing of the mounting leg 23 are offset. As a result, the section modulus of the fishing rod main body 11 gradually changes smoothly from the base end portion 14 toward the tip end portion 15. ing. Therefore, even if a small bending moment acts on the fishing rod main body 11, the fishing rod main body 11 is smoothly curved and deformed without forming a node at the portion where the line guide 12 is provided. In addition, when the bending moment is removed, the deformation of the fishing rod main body 11 is uniformly restored.

  Therefore, when the angler uses the fishing rod 10 to perform fishing targeting smelt fishing or other small fish, it is possible to make an effective “invitation” by delicately manipulating the mechanism, and the small fish You can capture Atari reliably. In addition, since the fishing rod body 11 is softly deformed in response to the pull of the hit fish, the hit fish is prevented from falling off the fishhook.

  Moreover, in this embodiment, the cross-sectional shape of the fishing rod main body 11 is formed in the flat rectangle, and the fishing rod main body 11 is formed in strip | belt shape. For this reason, the fishing rod main body 11 can be curved and deformed extremely sensitively when a bending moment is applied. Therefore, this fishing rod main body 11 can be suitably used especially for smelt fishing.
