Description

  The present invention relates to a swing rod used as a throw rod, and includes a swing rod having a fixed rod to which a fixed guide is attached and a swing rod having a reel sheet attached thereto.

The following are examples of fishing line guides for throwing rods.
As a fishing line guide, a fishing line guide which takes any form, whether for a parallel rod, a swing rod, a moving guide, or a fixed guide, is a cylinder that is externally mounted on the outer peripheral surface of the fishing rod. A boss-like leg portion, a support frame portion projecting outward from the leg portion, and a fishing line insertion guide frame portion attached to the support frame portion are configured.
If it is a moving guide, the cylindrical boss-like leg is fitted around the fishing rod so that it can be moved freely. If it is a fixed guide, the cylindrical boss-like leg is fitted around the fishing rod so that it cannot move. I was wearing it.

However, in the fishing line guide having the above configuration, when used as a throwing rod, the fishing line thrown together with the device has a high frictional resistance between the fishing line insertion guide frame portion, and the angler accurately throws it at the target point. It was sometimes difficult.
In addition, since the cylindrical boss part is externally fitted to the fishing rod as the leg portion, the elasticity of the rod itself is suppressed at the fitting portion, and there is little scenario of the whole fishing rod when throwing the device, and sufficient There was also a problem that the flying distance of the device could not be earned (Patent Document 1).

JP 2006-191833 A (FIG. 1)

Therefore, as shown in FIG. 5 in Patent Document 1, it has been considered to use a fishing line guide that is used for a row rod.
In other words, as shown in FIG. 5, this fishing line guide is a plate-like leg portion that is placed on the outer peripheral surface of the fishing rod and is fixed by winding the attachment yarn, and from the leg portion to the outer rod tip side. A support frame portion projecting toward the support frame portion and a guide frame portion for fishing line insertion attached to the support frame portion.
As a result, the above-mentioned drawbacks were solved, but another problem occurred.

In other words, when you finish fishing and want to drain the water from the swing rod, if you remove the bottom plug and put the swing rod in the vertical position, the upper rod will move to the bottom end side of the rod. The fishing-line guide support frame part or fishing-line insertion guide frame part that is fixedly attached to the front end of the base rod comes into contact with the open end of the front end of the base rod (the mouth) and is used for fishing lines. Sometimes it hurts a guide.
On the other hand, in the above-mentioned guide for a swing rod having a cylindrical boss-like leg, the leg is a cylinder even when the cylindrical boss-shaped leg abuts against the open end of the saddle on the side of the heel during the above draining operation. Since it is a boss shape, the fishing guide was rarely affected as far as it goes to the left.

  An object of the present invention is to provide a swinging rod that does not damage the fishing line guide when the fishing rod is drained and drained from the swinging rod while fully enjoying throw fishing.

[First Embodiment]
As shown in FIGS. 1 and 2, the fishing rod A for throwing fishing is composed of a tip rod 1, a second rod 2, a third rod (former upper rod) 3, and a marine rod 4. A top guide 1A is fixed to the tip of the spike 1 and three moving guides 1B are mounted at an intermediate position. A second guide 2 also has a fixed guide 2A and one moving guide 2B attached to the tip of the hook. Only the fixed guide 3A is attached to the heel end of the former heel 3. A reel sheet 5 is attached to the main shaft 4 at an intermediate position, and a spinning reel 6 and the like are mounted. A slightly large-diameter grip portion 4A is formed at the bottom end of the heel so that the auxiliary hand can grasp it tightly so that the posture of the fishing rod to be swung can be stabilized at the time of throwing fishing operation. It is.

  The head rod 1 and the like constituting the fishing rod A are manufactured as follows. That is, reinforced fibers c such as carbon fibers are aligned in one direction, and the aligned reinforced fiber group is impregnated with a thermosetting resin (or thermoplastic resin) such as an epoxy resin to form a prepreg sheet. A plurality of prepreg sheets cut into a substantially trapezoidal shape are wound around a mandrel, and a firewood material formed by winding a plurality of prepreg sheets is placed in a furnace in a state of being wound around a mandrel and fired. Decentering, taking out the cylindrical cocoon material, cutting the cocoon material into a predetermined length, and finishing it to make a casing.

  Specifically, as the reinforcing fiber c constituting the prepreg, glass fiber, aramid fiber, alumina fiber or the like can be used in addition to the carbon fiber, and as the resin, in addition to the epoxy resin, heat such as phenol resin or polyester resin can be used. A curable resin or a thermoplastic resin such as PV (E) can be used. Further, the prepreg may be configured by impregnating a woven fabric woven with reinforcing fibers with a resin.

  The parts attached to the former upper 3 will be described. As shown in FIGS. 1 and 2, the fixed guide 3A includes a plate-like leg portion 3a attached to the surface of the former upper collar, a support frame portion 3b projecting outward from the leg portion 3a, and the support. It is comprised with the guide frame part 3c for fishing line insertion attached to the flame | frame part 3b.

The plate-like leg portions 3a are placed apart from each other on the heel side and the buttock side, and have a slightly circular arc shape along the arcuate surface of the upper collar 3. The two plate-like leg portions 3a and 3a are fixed to the upper collar 3 with the attachment thread a.
The fishing line insertion guide frame portion 3c is positioned above the middle position between the plate-like leg portions 3a and 3a and is inclined slightly forward. The circular fishing line insertion hole is formed at the center position. A hard guide ring 3d is attached to the inner edge of the fishing line insertion hole.
The support frame portion 3b includes a single front support frame portion 3ba that rises rearward and upward from the tip side plate-like leg portion 3a and supports the lower end of the fishing line insertion guide frame portion 3c, and a heel side plate-like leg portion 3a. It consists of a pair of left and right rear support frame portions 3bb that support the left and right ends of the guide frame portion 3c that rises upward in the front and inserts the fishing line.
The fixed guide 3A is made of a metal material such as titanium or aluminum.

The mounting seat 7 is formed on the buttock side from the portion of the former upper collar 3 where the leg portion 3a is placed, and the ring-shaped stopper body 8 can be attached to the mounting seat 7.
The mounting seat 7 is a stainless steel part, is formed separately from the fishing rod A, is fitted into a predetermined position of the upper upper rod 3, and is fixed using an adhesive.

As shown in FIGS. 1, 2, and 6, the mounting seat 7 is formed as a stainless steel long cylindrical mounting tool, and has a large diameter flange on the tip side and the buttock side of the mounting tool. In addition to forming the portions 7A and 7B, a fitting mounting seat portion 7C for fitting and mounting the ring-shaped stopper body 8 is formed between the heel side heel portion 7A and the heel side heel portion 7B.
Although stainless steel is used as the material, titanium or the like may be used.

The surfaces 7a and 7b facing each other across the fitting mounting seat portion 7C in the heel side heel portion 7A and the heel side heel portion 7B are vertical surfaces substantially orthogonal to the axis X, whereas The inclined surface 7c is gently inclined from the apex of the portion 7A toward the tip end side end surface 7e to reduce the diameter, while the apex of the buttocks side flange portion 7B is further toward the hip end side end surface 7f. The inclined surface 7d is inclined to be reduced in diameter.
Further, at the apex of the heel side collar part 7A and the apex of the heel side collar part 7B, a sharp corner is not formed, but a rounded chamfer chamfer 7e is performed.

  As described above, the fixture 7 is made of stainless steel, but faces the apex of the heel side collar part 7A, the apex of the heel side collar part 7B, and the apex of the heel side collar part 7A from the heel side end. The inclined surface 7c and the inclined surface 7d from the apex of the heel side heel portion 7B to the end of the heel side are finished to have a smooth surface shape, so that even if the thrown fishing line comes into contact, it moves greatly. It is formed so as not to become a resistor.

Next, the resin ring-shaped stopper body 8 will be described. As shown in FIG. 5, the ring-shaped stopper body 8 is made using Duracon, which is a resin, and the surface itself is rich in smoothness.
However, other resins can be used as the ring-shaped stopper body 8.
That is, as another resin, as described above, ABS resin, nylon resin, and POM can be selected.
For example, in the case of POM, the trade name Duracon of Polyplustec or the trade name Delrin of Deyupon is adopted.
This material is molded into a ring shape. A mounting hole 8A is formed at the center, and the cross-section of the ring-shaped main body 8B surrounding the hole 8A is formed in a semicircular arc shape that gently expands the outer diameter from the tip side end surface 8a toward the intermediate portion 8b. The intermediate portion 8b is formed in a semicircular arc shape that is gradually reduced in diameter toward the buttock side end surface 8c, and is formed in a mountain shape as a whole from the heel side end surface to the buttock side end surface. The heel side end surface 8a and the heel end side end surface 8c are formed slightly on linear end surfaces orthogonal to the axis Y. The intermediate portion 8b is formed on a linear end face having a certain width parallel to the axis Y.

  In addition to such a configuration, a notch 8C that reaches approximately 90 degrees at a substantially circumferential angle is further provided at one place in the circumferential direction of the ring-shaped main body 8B. Due to the presence of the cutout portion 8C, the ring-shaped main body portion 8B can expand and contract the diameter of the mounting hole 8A at the center, thereby facilitating mounting on the fixture 7.

  As shown in FIG. 5 (a), a flat inclined surface 8d is formed on the opening end surface of the ring-shaped main body 8B from the left and right ends of the notch 8C. In a state where the stopper body 8 is mounted on the fixture 7, the left and right end surfaces of the notch 8 </ b> C are formed so as not to contact the fishing line. In addition, a cut surface 8e that cuts inwardly toward the axis Y is formed on the end surfaces of the inclined surface 8d that face each other, so that the cut is performed with the ring-shaped stopper body 8 attached to the fixture 7. The surface 8e does not protrude from the fixture 7.

  In a state where the ring-shaped stopper body 8 configured as described above is mounted on the fixture 7, the outer diameter D of the intermediate portion 8b of the ring-shaped main body 8B is larger than the inner diameter d of the tip side opening end 4a of the base rod 4. It has a large diameter. On the other hand, the outer diameter D1 of the flange portions 7A and 7B of the fixture 7 is smaller than the inner diameter d of the tip side opening end 4a of the base rod 4.

  As a result, as shown in FIG. 4 (b), when the ring stopper 8 is attached to the fixture 7 and the fishing rod is drained and washed with water after the fishing is finished, it can be attached even if the tail plug is removed. A part of the main rod side of the tool 7 enters the main rod 4, but the ring-shaped stopper body 8 comes into contact with the end surface of the front end 4a of the front end of the main rod 4 before the fishing line guide. The fixed guide 3A does not contact the main shaft 4, and the fixed guide itself is not damaged.

  Next, the connection between the fixed guide 3 </ b> A, the fixture 7, the ring-shaped stopper body 8 and the collar surface of the former collar 3 will be described. As shown in FIG. 4, the outer diameter D1 of the tip end surface 7e of the fixture 7 is formed larger than the outer peripheral surface diameter of the attachment thread a that fixes the plate-like leg portion 3a of the fixed guide 3A. ing. In addition, the outer peripheral surface formed in a semicircular arc shape that gently expands the outer diameter from the tip side end surface 8a of the ring-shaped stopper body 8 toward the intermediate portion 8b is attached to the fixture 7 in a state where it is attached to the fixture 7 7 is further smoothly connected to the inclined surface 7c from the tip end of the tip 7 toward the apex of the tip side flange portion 7A, and the outer diameter is gently increased from the intermediate portion 8b of the ring-shaped stopper body 8 toward the tip end side surface 8c. The outer peripheral surface is formed in a semicircular arc shape that reduces the diameter of the fitting 7 and is smoothly connected to an inclined surface 7d that is further directed from the apex of the buttock side flange portion 7B of the fixture 7 toward the buttock side end.

In addition to the above-described configuration, the outer diameter 3B on the buttock side of the upper heel 3 to which the fixture 7 is attached has an outer diameter substantially the same as the outer diameter of the buttock side end surface 7f of the fixture 7. It is formed so that the diameter is gently reduced from the same outer diameter portion toward the buttock side.
As described above, the fixed guide 3A, the fixture 7, the ring-shaped stopper body 8 and the hook surface of the upper rod 3 are arranged and connected so as not to be stepped. It has a configuration that does not.

  Moreover, since the outer diameter D1 of the flanges 7A and 7B of the fixture 7 is larger than the outer peripheral surface diameter of the attachment thread a that fixes the leg 3a of the fixed guide 3A, the fishing line that moves with the throwing operation. Also, the hooks 7A and 7B are blocked and contact with the portion of the attachment thread a wound around the leg 3a is suppressed.

  Further, as a mounting form of the ring-shaped stopper body 8, when the cutout portion 8C is mounted so as to be positioned on the buttock side of the leg portion 3a in the fixed guide 3A of the upper collar 3, the following is performed. I can say. That is, the outer diameter of the attachment thread a wound around the leg 3a and the mounting portion of the ring-shaped stopper body 8 are in a continuous state with few steps, and resistance is less likely to occur even if the thrown fishing line contacts.

The upper collar 3 to which the fixed guide 3A and the fixture 7 are attached will be described. As shown in FIG. 7, the prepreg sheet constituting the upper collar 3 is knitted in a state in which the reinforcing fibers c such as carbon fibers are crossed, whereby the fixing guide 3 </ b> A and the fixture 7. Resistance to deformation of the attachment site is increased.
Therefore, the opening shape of the tip side opening end of the upper collar 3 is not easily collapsed, and the second collar 2 is pulled out from the former collar 3 as a swinging collar, and the end of the collar end of the second collar 2 is The outer peripheral surface is inscribed in the inner peripheral surface of the tip side end portion of the upper collar 3 so that the extended state of the second collar 2 is stably maintained.

  Moreover, even when the fixture 7 is attached and fixed to the upper collar 3 by stabilizing the opening shape of the tip side opening end of the upper collar 3, the inner peripheral surface of the fixture 7 is the same as that of the upper collar 3. Since it is in close contact with the outer peripheral surface of the heel side end portion, the mounting state of the fixture 7 is also stable, the mounting state of the ring-shaped stopper body 8 attached to it is stable, and the heel side opening end of the base rod 4 Even when it comes into contact with it, it will come into contact with it reliably and exhibit a sufficient stopper function.
