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 fishing rod, for example, as disclosed in Patent Document 1, a configuration in which an elastic body made of synthetic resin or glass fiber is used as a tip rod with a thin flat structure is known. Thus, the tip sensitivity is enhanced by making the tip wings have a flat structure, and it is possible to easily grasp the hit of small fish such as smelt.
Shokai 51-62489

  By the way, since the tip of the tip has a thin and flat elastic body, the rigidity change is constant along the length direction, so when the fish is caught, only the tip part is slightly changed or the number of fish caught It becomes difficult to grasp. For this reason, it is conceivable to form a thin-and-flat-structured tip heel by laminating a composite material, specifically, a plurality of sheet-like members so as to have a change in rigidity along the axial direction. Further, peeling or the like is likely to occur between the respective materials, resulting in a problem in durability.

  The present invention has been made based on the above-described problems, and an object of the present invention is to provide a fishing rod provided with a tip rod having a high sensitivity and excellent durability.

  In order to achieve the above-described object, a fishing rod according to the present invention includes a flat-shaped tip rod formed by laminating a plurality of sheet-like members in which a reinforcing fiber is impregnated with a synthetic resin. And the plurality of sheet-shaped members include a main body sheet that forms a tip collar, and one or more reinforcing sheets that are shorter in the axial direction than the main body sheet and are laminated on the base end side. And an anti-peeling member is attached to a step formed when the sheet-like members are laminated.

  According to the fishing rod having the above-described configuration, since the tip rod is formed in a flat shape, the tip sensitivity is good, and it is possible to detect even small fish hits. In this case, the spikelet has a structure in which a plurality of sheet-like members are laminated, and the reinforcement sheet is laminated on the proximal end side, so that the rigidity change is applied to the spikelet along the length direction. It is possible to increase the sensitivity of the tip portion. In addition, since a peeling prevention member is attached to the step portion generated when the sheet-like member is laminated, peeling that is likely to occur when the tip end is bent can be prevented, and durability can be improved. .

  ADVANTAGE OF THE INVENTION According to this invention, the fishing rod provided with the tip rod of a structure with sufficient sensitivity and excellent durability comes to be obtained.

  FIGS. 1 to 5 are diagrams showing an embodiment of a fishing rod according to the present invention, FIG. 1 is a diagram showing an overall configuration, FIG. 2 is a side view showing a configuration of a tip rod, and FIG. 3 is a tip rod FIG. 4 is a side view showing the configuration of the peeling preventing member used for the tip, and FIG. 5 is a state where the peeling preventing member shown in FIG. 4 is attached. FIG.

  The fishing rod 1 of the present embodiment has a structure suitable for fishing a small fish such as a smelt, for example, and is configured as a so-called two-joint fishing rod in which a head rod 5 is joined to a main rod 3. Has been. In this case, the tip 5 is inserted into the front end opening 3 a of the base rod 3 while being held by the horizontal holding portion (insertion hole) 21 formed in the holding member 20. It is supposed to be joined by.

  The said main fence 3 is comprised by the tubular body, for example, wound the so-called prepreg sheet which impregnated the reinforced fiber (mainly carbon fiber, glass fiber, etc.) with the synthetic resin around the core, and passed through the heating process. Thereafter, it is formed in a predetermined size according to a conventional method such as decentering. On the outer periphery of the base end side of the main rod 3 formed in this way, a reel mounting portion (detailed configuration is not shown) for mounting the reel R around which the fishing line is wound is provided.

  In addition, the tip 5 is formed by laminating a plurality of sheet-like members in which a synthetic fiber is impregnated with a reinforcing fiber such as carbon fiber or glass fiber, and by thermoforming the sheet-like member, each sheet-like member is layered. It is formed in a flat structure that is in close contact with. Further, a fishing line guide 7 for guiding the fishing line fed from the reel R is attached to the outer surface at a predetermined interval.

  The sheet-like member to be stacked to form the tip collar is composed of a main body sheet 5A constituting the entire length of the tip collar 5, and a length in the axial length direction shorter than that of the main body sheet 5A. A reinforcing sheet is provided on the side. In this case, it is sufficient that one or more reinforcing sheets are laminated on the base end side, and in this embodiment, two reinforcing sheets 6A and 6B are laminated on the main body sheet 5A whose bending direction is the lower layer side. It has a structure.

  In the structure in which a plurality of (two or more) reinforcing sheets 6A and 6B are stacked on the main body sheet 5A in this way, the upper layer reinforcing sheet 6B is reinforced on the lower layer side as shown in FIG. It is preferable that the length is shorter than that of the sheet 6A, and the tip is made thicker as it moves toward the base end.

  Thus, in the structure in which the number of stacked layers increases as moving toward the base end side, a change in rigidity can be obtained stepwise along the length direction. That is, the rigidity on the base end side gradually increases and becomes difficult to bend, and the tip end side has low rigidity, so that it is easy to detect a fish hit on the tip end side.

  Moreover, it is preferable that the main body sheet 5A and the reinforcing sheets 6A and 6B laminated as described above are configured such that the lateral width gradually becomes narrower as the head sheet moves to the tip. Thus, even in the configuration in which the width changes along the length direction, the rigidity on the proximal end side gradually increases, and a configuration that is less likely to bend than the distal end side can be achieved.

  As described above, in the structure in which the sheet-like members (main body sheet 5A, reinforcing sheets 6A, 6B) are laminated, a stepped portion is formed at the boundary portion 8, and fish is caught and the tip of the tip is shown in FIG. When the ridge 5 bends downward, peeling easily occurs at the boundary portion 8. For this reason, as will be described later, a peeling prevention member 10 is attached to such a boundary portion (step portion) 8 to prevent peeling.

  Further, if the body sheet 5A and the reinforcing sheets 6A and 6B are too thick, problems such as an increase in rigidity and a decrease in sensitivity occur, and problems such as a decrease in bending strength and a breakage if the film is too thin. Therefore, the thickness of each sheet-like member is set in the range of 0.03 to 1.0 mm, preferably 0.05 to 0.3 mm.

  In this case, it is preferable that the sheet-like member to be laminated is formed thinner toward the upper layer side within the above-described range. By setting the laminated sheet-like members in such a thickness relationship, it is possible to obtain a structure that is difficult to peel off at the boundary portion 8 even if the tip end is bent as shown in FIG.

  Further, the main body sheet 5A and the reinforcing sheets 6A and 6B constituting each layer are mainly configured such that the reinforcing fibers are aligned in the axial length direction (unidirectional reinforcing fibers), but the reinforcing fibers are inclined. They may be aligned in the direction or woven. In this embodiment, the main body sheet 5A is a sheet material in which carbon fibers are aligned in the axial length direction, the reinforcing sheet 6A is a sheet material in which glass fibers are aligned in the axial length direction, and the same glass fiber for the reinforcing sheet 6B. It is comprised by the sheet material containing.

  In this case, it is preferable that the sheet-like member laminated as described above is composed of a material having a lower bending elastic modulus (a material having elongation) toward the upper layer side. According to such a configuration, even if the tip heel is bent as shown in FIG. 3, a structure that is difficult to peel off at the boundary portion 8 can be obtained.

  And the peeling prevention member 10 is adhere | attached on the step part used as the boundary part 8 of the sheet-like member (Main body sheet | seat 5A, reinforcement sheet 6A, 6B) laminated | stacked as mentioned above. As shown in FIG. 4, the peeling preventing member 10 of the present embodiment is configured as a thin film sheet that is deposited from the upper side of a laminated sheet-like member (hereinafter referred to as the thin film sheet 10).

  The thin film sheet 10 is made of, for example, a synthetic resin such as epoxy, polyester, or phenol, and preferably has a length that is at least as long as the first reinforcing sheet 6A laminated on the main body sheet 5A. That is, by using the thin film sheet having such a length, it becomes possible to cover all the boundary portions 8 at a time, and the deposition process can be easily performed. In particular, the thin film sheet 10 is longer than the main body sheet 5A as shown in FIG. 4, and as shown in FIG. Since the adherend layer 10 ′ is formed in a uniform state on the surface, it is possible to maintain the change in rigidity in the axial direction by the main body sheet 5 </ b> A and the reinforcing sheets 6 </ b> A and 6 </ b> B.

  Moreover, when depositing the thin film sheet 10, it is preferable to heat and shape | mold, applying the external pressure along a lamination direction. According to such a deposition process, the stepped portion generated in the boundary portion 8 becomes the gentle surface 8a, and the change in rigidity becomes gentle, so that the reinforcing sheet is more difficult to peel off. In addition, the smooth surface 8a may be formed in advance, for example, by crushing the end portion at the stage of the sheet before lamination or by cutting it diagonally.

  As described above, by attaching the thin film sheet 10 over the entire surface of the laminated sheet-like member, it is possible to reduce the thickness change as the flat-shaped tip 5 and the peeling due to stress concentration or It is possible to effectively suppress breakage and the like.

  According to the flat-shaped tip of the tip 5 configured as described above, it is possible to sensitively detect the delicate atari of a small fish such as a smelt, and the amount of deformation of the tip can be easily observed. This makes it easier to assume the number of fish. In this case, regarding the sheet-like members laminated as described above, it is easy to visually grasp the amount of deformation by providing a mark that can be visually recognized for each layer, and further, the number of fish hung It becomes easy to assume. For example, such a mark may be color-coded for each of the main body sheet 5A and the reinforcing sheets 6A and 6B, or may be provided with a marking on the boundary portion 8 described above.

  As mentioned above, although embodiment of this invention was described, this invention can be suitably deform | transformed other than above-described embodiment.

  In the configuration described above, a thin film sheet that is deposited over the entire surface is used as the peeling prevention member. However, as shown in FIG. Alternatively, a sheet may be attached to a part across the boundary portion 8.

  And in such a structure, you may make it fix together the fixed mounting part 7a of the fishing line guide 7 which guides the fishing line drawn out from the reel R (refer FIG. 1) using 10 A of peeling prevention members. It is also possible to combine the function of preventing peeling and the function of fastening the fishing line guide.

  Further, a surfactant may be interposed between the sheet-like members to be laminated in order to improve interlayer adhesion.

  In the embodiment described above, the main body sheet 5A is configured as the lowermost layer in the bending direction, but may be configured as the uppermost layer. In such a configuration, the main body sheet 5 </ b> A can be used as a peeling prevention member.

  Furthermore, the configuration (thickness, length, width, etc.) of the above-described sheet-like members to be stacked and the number of stacked layers are not limited to the above-described embodiment, and various modifications can be made. . For example, with respect to the main body sheet that constitutes the spike basket 5, a configuration in which a plurality of sheet materials having the same size are stacked may be used.
