Description

  The present invention relates to a fishing rod used for salmon fishing, mountain stream fishing and the like.

  It is important to obtain so-called hand sensitivity when fishing for salmon or mountain stream fishing. Movements of fish, fish, and hooks are transmitted to the angler's hands as vibration through fishing lines (lines) and fishing rods, but the degree to which movements of fish, etc. can be felt by hand is called "hand sensitivity". . If the hand sensitivity is high, that is, if the movement of fish, etc. is transmitted to the hand as vibrations etc., veteran anglers can know not only the clam but also the shape of the bottom of the water and the movement of surrounding fish. Is called.

  The following Patent Document 1 clearly states that hand sensitivity is high as "(Atari) is transmitted directly to the grip part via the heel so that even a small attack can be caught properly". A fishing rod is described. Patent Document 2 discloses a fishing rod in which a butt plug formed of titanium or the like is attached to a buttock portion. FIG. 4 shows an example described in Patent Document 2, and reference numeral 13 in the figure is a butt plug consisting of a buttock ring 13a formed of titanium or the like and a stone rubber 13b.

No. 1-8119 JP 2002-159248 A

  In Patent Document 1, the "grip portion" of the above-mentioned fishing rod is considered to be "thickly formed by overlaying the same material as the fishing rod on the outer peripheral portion of the fishing rod". The bag is generally formed of a fiber reinforced resin material or the like, but such a material includes a resin portion having a high vibration damping rate. Therefore, it is not always easy to sufficiently increase the hand sensitivity with the fishing rod described in Patent Document 1, and it is considered that it is necessary to adopt other special configurations together.

  In order to reduce the vibration damping rate, it is generally said that it is better to use a material having a high longitudinal elastic modulus and a low density. A high-rigidity and lightweight metal such as titanium is considered to have a low vibration damping rate in view of its characteristics, but in the example of Patent Document 2 (see FIG. 4), high hand sensitivity cannot be expected ( There is no description about hand sensitivity also in the document 2 concerned). In the example of the reference 2, the bottom ring 13a in the figure formed of titanium or the like is an extremely short part for attaching the rubber bump 13b and has a small area in contact with the palm. This is because the above configuration is not adopted.

  The invention according to the claims provides a fishing rod that has high hand sensitivity, and that makes it easy to feel the movement of a fish.

In the fishing rod of the present invention, a titanium or titanium alloy cylindrical body is connected near the buttocks, with the area that can be held by two or three fingers including the ring finger and a part of the palm exposed. It is characterized by The fishing rod shown in FIGS. 1 and 2 is an example of the present invention.
In the above, “a range that can be grasped by two or three fingers including the ring finger and a part of the palm” is when the end of the buttocks side is positioned near the little finger and the finger is held normally with one hand. A range that can be held in contact with a part of the palm (near the small ball) together with any of the ring finger, ring finger and middle finger, or little finger and ring finger and middle finger (two or three fingers). In length, it is approximately in the range of about 25 to 50 mm. "Exposed" means that the outer surface is not covered with other parts, coatings or the like. In addition, the “tubular body” is not limited to the one in which both ends are open, but includes the one in which the end on the butt end side is closed.

With such a fishing rod, when the fishing rod is gripped with one hand with the end on the side of the buttock near the little finger (see FIG. 2), the angler can obtain high hand sensitivity through the cylinder. It is possible to sense the movement of the fish. The cylinder made of titanium or titanium alloy has a large longitudinal elastic modulus and a low density, so the vibration damping rate is small. Therefore, the vibration according to the movement of the fish that is transmitted to the buttock side through the fishing line or the main body of the rod This is because it is faithfully conveyed to the angler's finger and palm. Titanium and titanium alloys are lightweight yet high-strength, so they are not easily deformed even when strong gripping force acts on them, and they have excellent corrosion resistance and are not easily rusted. It is suitable for use in fishing rod grips because it has the effect of suppressing metal allergies and not causing rough skin.
When holding a fishing rod for fishing rod or mountain stream fishing, usually hold it with either the left or right hand, and use the ring finger and the fingers before and after it to wrap the entire circumference around the buttock. Therefore, as described above, a cylinder made of titanium or titanium alloy is provided in a range that can be gripped by two or three fingers including the ring finger and a part of the palm, and if it is exposed, The transmission of vibrations takes place most efficiently and is almost the same as when a similar cylinder is provided in the area gripped by the entire palm. Titanium, which is more expensive than iron, aluminum, fiber reinforced resin materials, etc., is used, but the cost of fishing rods can be increased because the cylindrical body is short enough to be equivalent to the width of 2 to 3 fingers. It is minimized.
Note that the inventor has confirmed through an actual fishing test that even when the rod main body is made of a fiber reinforced resin material, the hand sensitivity is improved by providing the cylindrical body such as titanium near the buttocks as described above. It is also confirmed by the actual fishing test that the hand sensitivity is higher when the thickness of the cylinder is smaller.

In the above-mentioned fishing rod according to the invention, it is preferable that the total length of the above-mentioned cylinder does not exceed the range grasped by all the fingers and the palm. The fishing rod shown in FIG. 2 also corresponds to that.
The “full length of the cylinder” refers to the entire length of the cylinder including a portion inserted into the rod main body such as a male screw portion of the cylinder. "The range which can be grasped with all the fingers and the palm of the hand" means the range of about 10 cm from the buttocks side end.

The longer the exposed area and the longer overall length, the more advantageous the cylindrical body is in improving hand sensitivity and transmitting vibration to the angler. However, if the length of the cylinder is long, the cost increases as described above, and the rate of the increase is far from the improvement rate of the hand sensitivity, so the longer, the less preferable.
In addition, if the total length of the cylindrical body is long enough to exceed the range grasped by all the fingers and the palm of the hand, the eyelid main body tends to be easily damaged at the boundary with the cylindrical body. That is due to the following reason. A weir body made of a fiber reinforced resin material or the like is connected to a portion near the tip of the cylinder, and a bending moment acts on the weir body based on the load acting on the tip portion, so that the cylinder The bending moment is almost maximum near the border with the. When the total length of the cylinder exceeds the range that can be grasped by all fingers and palms, the main body of the eyelid can not be supported with one hand, so that the bending moment acts on the vicinity of the boundary as it is. As a result, the force is concentrated in the vicinity of the boundary of the crucible main body, and if not sufficiently reinforced, the crucible main body is easily broken or torn in the vicinity of the boundary.
In that respect, as described above, if the total length of the cylinder does not exceed the range grasped by all the fingers and the palm of the hand, the scissors body is not easily damaged as described above. The rod body near the boundary can be held using the thumb, index finger, or even a part of the palm of the hand (usually with one hand with a holding rod in such a way, see Fig. 2), near the boundary It is possible to manually support part of the bending moment acting on the

It is particularly preferable that the above-mentioned cylinder made of titanium or a titanium alloy has a thickness of 0.5 mm or more and 1.5 mm or less.
Titanium and titanium alloys have a high longitudinal elastic modulus and a low density. In addition, because of high rigidity and high strength, it is advantageous in that it can be formed thin to reduce its weight, and its vibration damping rate can be reduced. When the cylindrical body is made of titanium or a titanium alloy, the thickness can be 0.5 mm or more and 1.5 mm or less from the strength aspect. This is particularly advantageous for improving sensitivity.

The above cylinder is a cylinder open at both ends, and a butt plug is detachably attached to an end on the buttocks side, and the other end is detachably attached to a weir main body made of a fiber reinforced resin material It is also preferred that
The above-mentioned cylinder can be exchanged, using the same crucible main body as it is removable between a crucible main body. The above-mentioned cylinder used for the purpose of gaining hand sensitivity etc. has a length, weight, etc. that is easy to use depending on the angler, so if it is interchangeable, the fishing rod of the invention can be used by many anglers It will be preferred and used.
In addition, when the buttocks are detachably attached to the end portion on the buttocks side, the above-mentioned cylindrical body itself may be a cylindrical shape with both ends open, so that the above-mentioned cylindrical body is formed by machining etc. Can be made easy and the manufacturing cost of the fishing rod can be reduced.

It is further preferable that the crucible main body be made of a highly elastic carbon fiber reinforced resin material, and that the material has a resin ratio of 10 to 20% (in part or in whole).
The main body of high-elastic carbon fiber reinforced resin material, which has a very low resin ratio of 10 to 20% in the material, has a low vibration damping rate, so movement of fish and the like transmitted from fishing rods etc. Can be transmitted to the source side without weakening the vibration corresponding to the If the above-mentioned cylinder is attached in such a state that it is in direct contact with the main body of the crucible (that is, it is not in a non-contact state sandwiching other cylinders or packings of other materials), the cylinder Sharp vibrations are also transmitted to the body, giving the angler high hand sensitivity.

Further, it is more preferable that the crucible main body has a tip made of titanium or titanium alloy at its tip.
The tip made of titanium or titanium alloy can pick up the vibration from the fishing line sharply and transmit it to the heel side, and the hand sensitivity of the fishing rod can be effectively improved. Therefore, in the fishing rod having the above-mentioned cylinder near the buttocks, if the tip is made of titanium or titanium alloy, the hand sensitivity of the fishing rod is further enhanced.

  According to the fishing rod of the present invention, when the fishing rod is normally gripped with one hand with the end on the side of the buttock near the little finger, the angler can obtain high hand sensitivity and sensitively sense the movement of the fish. it can. In addition, since it is sufficient that the above-mentioned cylinder is short, the cost increase of the fishing rod can be suppressed, and it is advantageous also in the sense that the rod body can be supported by hand to prevent damage.

It is a figure which shows one Embodiment of invention, and is a longitudinal cross-sectional view which shows the buttocks vicinity of a fishing rod. It is a side view which shows the state which hold | maintained the buttocks vicinity of the fishing rod of FIG. 1 with one hand normally. It is a whole side view of the fishing rod of FIG. It is a longitudinal cross-sectional view which shows the buttocks vicinity of the conventional fishing rod.

One example of a fishing rod according to the invention is shown in FIGS.
The illustrated fishing rod is a fishing rod as shown in FIG. 3 which is used for fishing and uses a plurality of rods 1B, 1B ... and a tip 1X which are contained in the main rod 1A, as shown in the drawing. It is. In FIG. 1 and FIG. 2, the vicinity of the buttocks of the former eyelid 1A is expanded and shown.

  The crucible main body 1 configured by the main crucible 1A and the plurality of crucibles 1B is formed of a fiber-reinforced resin material as a main material. That is, a plurality of carbon sheets (carbon fibers) are wound, and they are adhered with an epoxy resin or the like, and heated and pressurized to form a cylindrical shape, thereby constituting each weir 1A and 1B. By using a highly elastic carbon sheet (for example, 50 ton carbon or more), the bag body is made highly elastic. Further, in order to further reduce the vibration damping rate, low resin carbon having a resin rate of 10 to 20% is used.

  A cylinder made of titanium or a titanium alloy (for example, pure titanium or beta titanium) in the vicinity of the rear end portion (the buttocks) of the base 1A shown in FIG. 2 is connected. Titanium and the like can be formed thin because of high strength, and the thickness of the cylindrical body 2 in the drawing is 1.1 mm at the thickest portion and 0.9 mm at the thin portion.

The front end of the cylindrical body 2 forms a male screw 2a and is connected to the inside of the crucible main body 1, and the rear end forms a female screw 2b and is connected to a below-described butt plug 3. Although the rod body 1 and the cylindrical body 2 sandwich an O-ring p in part, the two are in direct contact with each other at the screw portion. The same applies to the space between the barrel 2 and the butt plug 3.
The axial length of the cylindrical body 2 is about 40 mm in total length, and the length of the male screw 2a is about 5 mm. The length of the butt plug 3 is about 5 mm. Therefore, in the cylindrical body 2, the metal surface is exposed over a length of about 35 mm from a point about 5 mm away from the butt end of the heel.

  The butt plug 3 is for closing the butt end, and is a component including a screw portion coupled to the female screw 2b of the cylindrical body 2 and a plate 3a at the rear thereof. The main body is made of stainless steel, and rubber layers 3b and 3c are baked on the front (inner) surface and the rear (outer) surface of the plate 3a. These rubber layers 3b and 3c are for absorbing an impact that occurs when the crucible 1B is stored.

  FIG. 2 shows a state in which the fishing rod of FIGS. 1 and 3 is held by the right hand. When the bottom plug 3, that is, the end of the buttocks side is positioned near the little finger and the fishing rod is gripped normally, as shown in the figure, two or three fingers including the ring finger and a part of the palm (the part closer to the little finger) ), The user holds the exposed cylindrical body 2.

When holding it as above, generally, it will be held so as to wrap substantially the entire circumference of the cylinder 2 with the two or three fingers and the palm of the hand. The cylindrical body 2 is made of titanium or a titanium alloy and has high strength, so there is no risk of deformation or the like even if gripped firmly.
Since both the cylindrical body 2 thinly formed of titanium etc. and the rod body 1 made highly elastic as described above have a small vibration damping rate, the vibration transmission characteristic of this fishing rod is extremely high. Moreover, since the user of the fishing rod grips the barrel 2 in the exposed state as described above, the vibration transmitted to the barrel 2 can be sensed sharply, and high hand sensitivity can be obtained from the fishing rod.

  The tip 1X shown in FIG. 3 is generally formed of a fiber-reinforced resin material in the same manner as the heel 1B, but can be made of titanium or a titanium alloy. If it does so, since vibration attenuation | damping can also be suppressed notably in the tip 1X, it is possible to further improve the hand sensitivity of this fishing rod.

  Since the overall length of the cylinder 2 is shorter than the full width of the palm, when holding a fishing rod as shown in FIG. 2, the index finger and thumb and a part of the palm (the part closer to the index finger) are the cylinder 2 (the male screw 2a). It will be in the state of grasping and supporting the main body 1 of the eyebrow at the tip of the part). In this state, a part of the mechanical load acting on the scissors body 1 can be naturally supported by hand. Therefore, in the vicinity of the boundary with the cylinder 2, it is difficult for trouble to cause damage to the heel body 1 due to a bending moment or the like.
