TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fishing rod, and in particular, a fishing rod in which a grip portion is formed in a cylindrical portion arranged on the side of the rod, and an original rod tube extending from a tip portion of the grip portion is formed of a rod tube having a smaller diameter than the cylindrical portion. About.
[0002]
[Prior art]
Usually, in the case of a fishing rod formed of a lightweight and small-diameter rod tube, such as a fishing rod used for tenkara fishing in mountain streams, a large-diameter grip is provided on the rod end side to make it easier to grip. It is necessary to make the diameter larger than the original rod pipe. Also, when forming a mounting portion for a fishing reel, it is necessary to increase the diameter of the grip portion.
[0003]
Regarding such a grip portion, for example, Japanese Utility Model Publication No. 57-48379 discloses that in order to adjust the length of a fishing rod, it is detachably attached to a second rod pipe of a swing-out type fishing rod or a rod pipe further on the tip side than this. Possible replacements are listed. The replacement grip, which is a grip portion, is a double grip in which an inner pipe capable of fixing a second rod pipe is fixed in an outer gripping pipe through two annular joints provided on a rod end side and a tip side. Equipped with a pipe structure. The annular joint for fixing these two pipes is formed of metal or plastic, and the annular joint on the tip side is formed in a tapered shape that smoothly transitions from the outer diameter of the gripping pipe to the outer diameter of the inner pipe. . By adjusting the wall thickness of these two annular joints, the diameter of the gripping pipe is made easier for the angler to grip without being affected by the change in the diameter of the inner pipe and therefore the rod pipe connected thereto. It can be of a fixed size.
[0004]
[Problems to be solved by the invention]
However, in the grip portion as described above, an annular joint for fixing the gripping pipe and the inner pipe is formed of a hard member such as a metal. For this reason, especially when operating while gripping the front part of the grip portion, the rigid annular joint is pressed, and it is easy to get tired when gripping for a long time, and pain is particularly hurt when gripping strongly. May occur. Further, the tapered shape of the annular joint on the distal end lengthens its axial length, and the exposed portion of the rod pipe is separated from the grip portion toward the distal end. If an attempt is made to touch the rod tube directly with a fingertip in order to easily detect a hit and perform a fine operation, a large-diameter grip portion cannot be gripped, and good gripping properties cannot be obtained.
[0005]
The present invention has been made in view of such circumstances, and has an object to provide a fishing rod having a grip portion having good gripping properties and improved operability even when the rod pipe has a small diameter. .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the fishing rod of the present invention has a grip portion formed on a cylindrical portion arranged on the side of the rod, and an original rod tube extending from a tip portion of the grip portion is a rod tube having a smaller diameter than the cylindrical portion. The formed fishing rod is characterized in that a flexible member softer than the cylindrical portion is disposed at a step between the distal end of the cylindrical portion and the rod tube forming the original rod.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 3 show a fishing rod 10 according to a preferred embodiment of the present invention.
As schematically shown in FIG. 1, a fishing rod 10 according to the present embodiment has a middle rod 16 connected between a large-diameter original rod 12 located on the bottom of the rod and a tip rod 14 on the tip side. It is formed together. In the present embodiment, a fishing line binding portion 18 is provided at the tip of the tip rod 14 so as to form a fishing rod having a small diameter overall suitable for mountain stream fishing. The tip rod 14 and the middle rod 16 are formed in a projecting structure that is joined at joints P1 and P2 between the base outer peripheral surface and the distal end inner peripheral surface of each rod tube. Can be stored in
[0008]
Each of the pipes forming the former rod 12, the middle rod 16 and the tip rod 14 is formed by winding a fiber reinforced prepreg (FRP) in which a reinforcing fiber is impregnated with a synthetic resin around a core metal, and then hardening, decentering, etc. Is formed through the usual process. Although the rod tube of the present embodiment is formed from a hollow rod tube in which a plurality of main layers are laminated, the present invention is not limited to such a hollow structure, and the whole or a solid structure capable of largely bending a fishing rod is provided. Part can also be formed. In the case of such a solid structure, another appropriate joining type such as a parallel joining type or an inro joining type may be adopted.
[0009]
Further, the number of intermediate rods 16 between the former rod 12 and the head rod 14 is not limited to one as shown in the figure. It is also possible to arrange a plurality of joints, and in the case of providing a plurality of joints, it is possible to combine various joint types. In the present embodiment, the angler A grip part 20 having a large diameter is arranged so that it can be easily gripped, and the rear end of the grip part 20 is preferably made of a synthetic resin such as nylon or EVA resin (ethylene vinyl acetate resin). The fishing rod 10 is attached by a detachable method such as screwing, for example, and the end of the fishing rod 10 on the side of the rod end is closed. The grip portion 20 can be formed to have an appropriate length. However, the entire length of the original rod 12 including the grip portion 20, that is, approximately 1/3 of the length from the butt plug part 21 to the joint portion P2. It is preferably formed to a length of about １ ／. By forming the grip portion 20 with such a length, the grip portion can be gripped at an arbitrary position, and operability is improved.
[0010]
As shown in detail in FIG. 2, the original rod 12 has, for example, a cylindrical portion having a larger diameter than the original rod tube, that is, a cylindrical body, on the rod end side of the original rod tube 22 having an outer diameter of 10 to 18 mm. 24, a grip portion 20 is formed on the cylindrical body 24. In the present embodiment, the tubular body 24 and the former rod tube 22 have a separate structure. This cylindrical body 24 is formed by FRP similar to a rod tube, for example, to a length of about 150 to 300 mm having a constant dimension of an outer diameter of 15 to 25 mm, an inner diameter of 13 to 24 mm, and a wall thickness of about 1 mm. It is. Instead of the FRP, the cylindrical body 24 may be formed of a synthetic resin, metal, wood, or the like, and the surface of such a cylindrical body 24 may have an appropriate pattern such as an uneven pattern or a non-slip material. By means, a non-slip treatment may be performed.
[0011]
The rear end side of the original rod tube 22 is inserted into the cylindrical body 24 from the opening on the distal end side to an intermediate position thereof, and a space 26 is inserted between the buttocks plug component 21 and the rear end of the original rod tube 22. To form By forming such a space portion 26 in the tubular body 24, the weight of the original rod 12 can be reduced. Further, when the fishing rod 10 is formed in a swinging structure, even when the middle rod 16 and the head rod 14 are stored in the original rod 12 in a state of being wet with water, the rod pipe is passed through the space 26. Drying can be promoted. Furthermore, since the rear end side of the main pole 12 is relatively lightweight, the front end side becomes relatively heavy, and the center of gravity moves to the tip side. For this reason, when throwing while gripping the rear of the grip portion 20 near the rod bottom, this throwing operation becomes easy. It is preferable that such a space 26 be formed over a length of about half of the cylindrical body 24. The tubular body 24 may be formed integrally with the original rod tube 22 instead of being formed as a separate member as described above. In the case of an integral structure, it is preferable to form a step portion described later at the tip of the tubular body 24.
[0012]
Further, an intermediate spacer 28 made of a material having a low specific gravity is interposed between the original rod tube 22 and the cylindrical body 24. When a resin material is used, the intermediate spacer 28 is preferably made of a foamable resin material having a large expansion ratio, such as polyethylene or polyurethane, when formed as a foam material. It is also possible to use a natural material such as cork. In any case, when formed as the intermediate spacer 28, the surface hardness is high, and it is easy to be firmly connected to both the original rod tube 22 and the cylindrical body 24.
[0013]
Such a spacer 28 is disposed over the entire portion except for the end of the overlapping portion between the original rod tube 22 and the cylindrical body 24, and can be fixed to both the original rod tube 22 and the cylindrical body 24 with an adhesive or the like. preferable. By adhering to both the original rod tube 22 and the cylindrical body 24, the shape retention of the original rod tube 22 and the cylindrical body 24, that is, the ability to maintain the initial shape is increased. Thereby, while maintaining the lightweight structure of the original rod 12, even when the grip portion 20 is strongly squeezed and shakes strongly, the external shape of the cylindrical body 24 is maintained, and a large resistance to bending is formed. I do.
[0014]
In addition, such a spacer 28 may be formed from a plurality of members divided in the axial direction or the radial direction as long as the shape retention of the original rod tube 22 and the cylindrical body 24 can be improved. Alternatively, the weight may be reduced by forming recesses (not shown) at equal intervals on at least one of the outer surface facing the original rod tube 22 and the inner surface facing the cylindrical body 24, for example.
[0015]
Further, a front spacer 30 is arranged on the front end side of the intermediate spacer 28, that is, on the step formed between the original rod tube 22 and the tubular body 24, and is accommodated in the rear end side, that is, the tubular body 24. A rear spacer 32 is disposed at the rear end of the main rod tube 22. The front spacer 30 and the rear spacer 32 are formed of a soft member, for example, EVA resin, rubber, elastomer, or the like, which is softer or more easily deformed than the intermediate spacer 28 and the cylindrical body 24 in order to reduce stress concentration. Is preferred. Since the rear spacer 28 is disposed in the tubular body 24 without being exposed to the outside, it can be formed of metal or reinforced wood, in addition to the same material as the front spacer 30. It is preferable that these spacers 30 and 32 are firmly fixed to the original rod tube 22 and the tubular body 24 with an adhesive or the like. Instead of directly contacting the intermediate spacer 28, a gap may be provided between the spacers so as not to affect the shape retention. In this case, the weight of the original rod 12 can be further reduced.
[0016]
The rear spacer 32 of the present embodiment has an annular portion 32a surrounding the rear end of the original rod tube 22, and an extension 32b protruding from the rear end of the original rod tube 22, and the inner periphery of the extension 32b. The surface is formed as a tapered surface 33 whose diameter increases toward the space 26. This tapered surface 33 is used to remove the buttocks plug component 21 and pull out the inner rod 16 from the former rod 12, and then when the inner rod 16 is inserted into the former rod 12 again, the tip of the inner rod 16 is connected to the former rod pipe. It functions to smoothly guide the inside of the tube 22. Accordingly, even when the rear spacer 32 is formed of a material softer than the rod tube or the cylindrical body, it is possible to prevent the rear spacer from being damaged by the middle rod 16. Also, the rear end of the original rod tube 22 forms a tapered surface similar to the tapered surface 33 of the rear spacer 32, and the inner rod 16 guided by the tapered surface 33 of the rear spacer 32 is inserted into the inner hole of the original rod tube 22. It is also possible to smoothly guide the inside.
[0017]
On the other hand, the front spacer 30 has an annular portion 30 a housed at the front end of the tubular body 24 and an extension 30 b protruding from the front end of the tubular body 24. The outer peripheral surface of the extension portion 30b is formed in a truncated conical shape having a tapered surface 31 whose diameter decreases toward the distal end side, and the maximum diameter portion on the rear end side has an outer diameter larger than the cylindrical body 24. Have. In the extension portion 30b of the present embodiment, the annular end surfaces formed on the front end side and the rear end side are arranged perpendicular to the axis of the original rod tube 22, and therefore, when the grip portion 20 is gripped, The thumb or the index finger can be easily locked. Reference numeral 34 denotes a decorative base having a thin structure, which can also prevent stress concentration on the front end portion of the front spacer 30 and the original rod tube 22.
[0018]
The length of the frusto-conical extension 30b is preferably 15 mm or less, particularly preferably 10 mm or less when the axial dimension s is in the range of 2 to 20 mm. With such dimensions, even when the grip portion 20 is gripped, the original rod tube 22 and the cylindrical body 24 can be simultaneously brought into contact with the fingertip, and a slight contact can be sensed through the original rod tube 22. On the other hand, even when the axial dimension s is longer than this, if this dimension is 50 mm or less, at least one of the index finger and the thumb may be attached to the original rod tube 22 while holding the grip portion 20. By contacting with, a slight contact can be sensed. Further, it is preferable that the dimension r of the extension 30b protruding in the radial direction from the outer peripheral surface of the tubular body 24 is 0.5 to 1.0 mm. By setting the extension amount of the extension portion 30b in the radial direction to such a size, a finger can be locked to the projection portion to prevent the fishing rod 10 from moving backward, thereby improving operability. Further, even when the extension 30b is pressed by a finger and deformed, the edge of the tubular body 24 is prevented from being exposed, thereby preventing the angler's finger from being damaged and the tubular body 24 being prevented from being damaged. 24 edges are protected. Further, the size of the maximum diameter portion of the extension portion 30b projecting from the outer peripheral surface of the original rod tube 22, that is, the radial dimension t is preferably in the range of 3 to 10 mm and 5 mm or more. By doing so, a finger can be easily hooked on the front end of the front spacer 30, and operability can be improved.
[0019]
The annular portion 30a of the front spacer 30 and the annular portion 32a of the rear spacer 32 are formed in appropriate axial dimensions as long as they can be fixed to the original rod tube 22 and the tubular body 24 using an adhesive or the like. can do. Further, a concave portion similar to the intermediate spacer 28 may be formed on at least one of the outer surface portion and the inner surface portion.
[0020]
FIG. 3 shows a state where the former rod 12 is gripped during actual fishing.
As shown in the figure, the thumb and the forefinger are hung on the front spacer 30 in a state where the large-diameter grip portion 20 of the original rod 12 is gripped in the palm with three fingers, the middle finger, the ring finger and the little finger. Then, the original rod tube 22 can be directly touched with the fingertip. Since the front spacer 30 is formed of a soft and flexible member that is more easily deformed than the original rod tube 22 and the cylindrical body 24, it is hard to be tired even if it is held for a long time, and furthermore, it strongly presses the thumb and the forefinger. Even without causing pain in the hands, extremely good gripping properties can be obtained. Moreover, by operating the front spacer 30 with the thumb and forefinger without switching the grip portion 20, the original rod 12 can be moved forward or backward, and extremely good operability can be obtained.
[0021]
When the fishing rod 10 is suddenly operated upon sensing a hit, even if a large bending force acts on the grip portion 20, the spacers 28, 30, 32 disposed between the tubular body 24 and the original rod tube 22 are provided. As a result, since the shape retaining force of the tubular body 24 is improved, so-called curving is prevented. Furthermore, for example, when the near end of the rod end of the former rod 12 is gripped for long throw, the center of gravity is located relatively forward, so that the throwing operation is easy.
[0022]
4 and 5 show a modification of the front spacer 30. FIG.
The front spacer 30 shown in FIG. 4A is formed in a structure in which the outer peripheral surface of the extension 30b has a cylindrical shape. Further, the front spacer 30 shown in FIG. 4B has an outer peripheral surface of the extension 30b from the outer peripheral surface of the cylindrical body 24 to the outer peripheral surface of the original rod tube 22 which is steeper than the front spacer shown in FIG. It is formed on a tapered surface extending at an angle to provide a suitable gripping property. In any case, it is preferable to form the same size as the front spacer 30 shown in FIG.
[0023]
The front spacer 30 shown in FIG. 5 has the same shape as the embodiment shown in FIG. 2, but is a modified example formed of a material which is particularly easily deformed. Also in this case, the outer peripheral edge of the cylindrical body 24 is formed so as not to be exposed when the outer peripheral surface of the extension 30b is pressed with a finger.
[0024]
FIG. 6 shows a modified example in which the tubular body 24 of the grip portion 20 is formed integrally with the original rod tube 22.
In the modification shown in FIG. 6A, a relatively steeply tapered transition portion 23 between the original rod tube 22 and the front end of the tubular body 24 forms a step. A flexible member 40 is fixed to the outer peripheral portion of the transition portion 23 with an adhesive or the like, and the flexible member 40 has a locking surface formed by the same outer peripheral surface as the extension portion 30b of the front spacer shown in FIG. 41. Further, in the modification shown in FIG. 6B, the tapered transition portion 23 is formed with a relatively gentle inclination. For this reason, the flexible member 40 has an adjusting portion 40a for adjusting the outer diameter, and a locking surface 41 is formed on the outer peripheral surface of the extension portion 40b extending to the distal end side of the adjusting portion. The outer peripheral surface of the adjusting portion 40a is formed to have the same diameter as the outer peripheral surface of the tubular body 24. In each of the modified examples shown in FIG. 6, it is preferable that the original rod tube 22 and the tubular body 24 have the same dimensions as those of the embodiment shown in FIG.
[0025]
【The invention's effect】
As is clear from the above, according to the present invention, even if the rod tube has a small diameter, it is possible to extremely easily and inexpensively form a fishing rod having a grip portion with good grip and improved operability.
