Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to
The present invention relates to a through rod having a plurality of rod bodies connected in a swinging-out manner and through which a fishing line can be inserted.

[0002]

2. Description of the Related Art A swing-type through rod has a plurality of rod bodies having a fishing line insertion path therein. The rods on the tip side can be stored inside the rods on the base side. Generally, a line introduction hole for guiding a fishing line to an internal line for inserting a line is formed in an outer peripheral portion of the former rod.

[0003] In such a center rod, the fishing line from the reel is introduced into the line insertion path inside the rod body through the line introduction hole. Then, it is guided to the top guide at the tip of the tip of the spike through the thread insertion path inside each rod body, and is led out from the top guide. When the rod is extended in use, the outer periphery of the upper rod stored in the former rod (hereinafter referred to as the front end of the rod and the rear side of the rod base) is connected to the inner rod that is connected in the form of a swing. The fitting is fixed to the inner circumference of the front part of the original rod.
When storing the rod, the rear end of the upper rod can be pushed into the vicinity of the rear end inside the former rod. For this reason, when a line introduction hole is formed in the original rod, at the time of storage, the fishing line introduced from the line introduction hole is drawn along with the outer peripheral surface of the original rod to near the rear end of the original rod, It is folded back at the bottom of the former pole and introduced into the former pole.

[0004]

In the above-mentioned swing-out center rod, the fitting portion of both of them is precisely finished to almost the same diameter in order to firmly fit the former rod and the former rod. Have been. For this reason, the gap between the outer peripheral surface of the former upper rod and the inner peripheral surface of the former rod is small even on the rear side of the fitting portion. Therefore,
When the former rod is stored inside the former rod, there is a possibility that the fishing line may bite into the gap between the rear end edge of the line introduction hole formed in the former rod and the outer peripheral surface of the former rod.

[0005] Further, once the former rod is stored inside the former rod, the fishing line easily adheres to the outer peripheral surface of the former rod by water or the like. In such a case, if the stored original rod is extended from the original rod, the fishing line adhering to the outer peripheral surface of the original rod will move with the original rod as the original rod moves. There is a possibility that the fishing line may enter the fitting portion with the rod or the gap between the upper rod and the front end of the line introduction hole, and bite into these portions.

[0006] Such a problem similarly occurs when a thread introduction hole is formed in a rod body on the tip side other than the original rod and the rod body on the tip side is further housed in the rod body. An object of the present invention is to make it difficult for a fishing line to bite when a rod is extended or contracted in a swing-through type through rod.

[0007]

The boring rod according to the first aspect of the present invention is capable of penetrating fishing line therein and has an inner rod body and an outer rod body. The inner rod body has a line insertion path through which the fishing line is inserted. The outer rod body is capable of storing the inner rod body therein, and has a line introduction hole formed in the outer peripheral part for introducing fishing line into the line for inserting a line, and a rod base side of the inner rod body formed in a rod tip side part. A fitting portion where the portion is fitted,
A relief portion formed closer to the rod base than the fitting portion and having an inner diameter larger than the inner diameter of the fitting portion.

[0008] In this hollow rod, the inner rod is stored in the escape portion inside the outer rod when stored. In use, the inner rod body is pulled out from the outer rod body, and the rod base side of the inner rod body is fitted and fixed to the fitting portion on the rod tip side of the outer rod body. At this time, the fishing line is introduced from the line introduction hole of the outer rod body into the line insertion path of the inner rod body, and penetrates the inside of the inner rod body.

Here, inside the outer pole body, the escape portion behind the fitting portion is formed with a relatively large inner diameter, so that the clearance between the outer peripheral surface of the inner rod body and the inner peripheral surface of the outer rod body is formed. The gap is larger than before. Therefore, when the inner rod body is extended and contracted with respect to the outer rod body, the fishing line is less likely to bite between the inner rod body and the outer rod body. A boring rod according to a second aspect of the present invention is the boring rod according to the first aspect, wherein the boundary between the fitting portion and the escape portion is stepped, and the stepped portion is the end of the thread introduction hole on the rod tip side. It is located closer to the pole tip. Here, a large gap is always ensured between the front end edge of the yarn introduction hole and the inner rod body. Therefore, particularly when the inner rod body is extended, the fishing line is less likely to bite between the inner rod body and the front edge of the line introduction hole.

The boring rod according to a third aspect of the present invention is the boring rod according to the second aspect, wherein, in use, the rod-side end surface of the inner rod is located closer to the rod end than the rod-end side end of the thread introduction hole. doing. Here, when the inner rod is extended, the end face on the rod base side of the inner rod can be easily confirmed from the thread introduction hole, so that threading can be easily performed.

And a fitting seat 22 fitted inside the plug 21. The cap 20 is made of an elastic body, and is fitted so as to cover the rear end of the plug 21. The plug portion 21 is a substantially cylindrical member, and a male screw portion 23 that is screwed into a female screw portion formed at the rear end of the original rod 1 is formed on an outer peripheral surface of a substantially front half portion. A fitting seat 2 is provided on the inner peripheral surface of the plug 21.
2 is fixed by bonding. The fitting seat portion 22 is a substantially cylindrical member made of an elastic material formed of a material such as rubber, and has a flange portion 24 having an outer diameter slightly smaller than the inner diameter of the original rod 1 in the middle. The front end of the plug portion 21 is in contact with the right side (rear surface) of the flange portion 24 in FIG. On the left side (front side) of the flange 24 in FIG. 4, a small-diameter projection 25 having a curved surface at the corner of the tip is formed.

[Former pole] On the outer periphery of the front part of the former pole 2,
As shown in FIGS. 1 to 3, a line introduction hole 13 for introducing the fishing line L wound around the spinning reel 10 into an internal line for insertion is formed. The predetermined range including the portion where the yarn introduction hole 13 of the former upper rod 2 is formed is the yarn introduction hole 1.
In order to suppress a decrease in bending strength due to the formation of No. 3, the thick portion 16 is thicker than other portions. At the rear of the line introduction hole 13, a line introduction guide 14 for guiding the fishing line L to the line introduction hole 13 is detachably mounted.

In the front part of the upper rod 2, a mating part (fitting part) 45 having an inside diameter substantially equal to the rear part of the intermediate rod 3, as shown in FIG. The joining portion 45 is provided behind the joining portion 45.
A relief portion 46 having a larger inner diameter is formed. The escape portion 46 is continuous to the rear end of the former upper rod 2, and is formed in a tapered shape so as to have the same diameter or gradually increase to the rear end. A step portion 47 is formed at the boundary between the fitting portion 45 and the escape portion 46. FIG. 6 shows a use state in which the rear part of the intermediate rod 3 is fitted to the mating part 45 of the upper rod 2, and the rear end face of the intermediate rod 3 is the front end edge of the thread introduction hole 13 as shown in the figure. It is located behind.

By forming the stepped portion 47 in front of the front end edge of the thread introduction hole 13 in this manner, as described later in detail, when the rods 1-4 are expanded and contracted, the outer periphery of the intermediate rod 3 is extended. It becomes difficult for the fishing line to bite between the surface and the edge of the line introduction hole 13. [Yarn Introduction Guide] As shown in FIGS. 6 and 7, the yarn introduction guide 14 is a cylinder which can be freely adjusted in the axial direction with respect to the thick portion 16 of the former rod 2 and which is detachably mounted. It has a guide body 30 in the shape of a circle. The guide body 30 includes a mounting portion 33 in which a through hole 32 is formed to be fitted into the thick portion 16, and a through hole 34 formed in the outer peripheral side of the mounting portion 33 and directed obliquely inward toward the front. And a guide portion 35 having the same. The introduction pipe 31 is fitted into the through hole 34 of the guide portion 35. Mounting part 33 and guide part 35
Between the two through holes 32 and 34
Are formed. A fixing bolt 37 and a nut 38 are mounted between the mounting section 33 and the guide section 35. By screwing the fixing bolt 37 to the nut 38 and tightening it, the slit 36 is narrowed,
3 is fixed to the thick portion 16 of the upper pole 2, and the introduction pipe 31 fitted in the through hole 34 is firmly fixed in the hole 34.

The introduction pipe 31 includes a pipe body 39 and a hard ring 40 attached to the front and rear ends of the pipe body 39.
a, 40b (a rod-side yarn guide ring and a rod-end-side yarn guide ring). The inside diameter 41 of the pipe body 39 increases from the front end to the rear end, and the inside diameter at the rear end is the largest. The pipe body 39 has a large-diameter flange at the rear end, and the diameter of the through hole 34 is also large corresponding to this flange. For this reason, the introduction pipe 31 can be mounted from the rear end side of the through hole 34. The hard rings 40a and 40b are connected to the pipe body 39.
Are fixed to the inner peripheral portions at both ends. The inner diameter of the front hard ring 40b is smaller than the inner diameter of the rear hard ring 40a. The hard ring 40b is located forward of the rear end of the yarn introduction hole 13 and rearward of the front end. Further, the lower end of the hard ring 40b is located on the inner peripheral side of the outer peripheral surface of the former upper rod 2 and on the outer peripheral side of the inner peripheral surface.

The arrangement of the hard ring 40b makes it difficult for the fishing line to bite into the upper rod 2 when the rods 1 to 4 expand and contract, as described later. As shown in FIG. 4, the tail plug 6 of the upper rod 2 includes a substantially cylindrical plug 50 and a contact portion 51 fitted to the front of the plug 50. Have. The inner peripheral part of the plug part 50 is fitted to the outer peripheral part of the projection part 25 of the tail plug 5 attached to the original rod 1, so that the tail plug 5 and the tail plug 6 are fixed in the stored state. I have. On the outer peripheral surface of the substantially front half portion of the plug portion 50, a male screw portion 53 screwed to a female screw portion formed at the rear end of the former upper rod 2 is formed. As shown in FIG. 5, four protrusions 52 are formed on the contact portion 51 at intervals in the circumferential direction. The projection 52 contacts the rear end of the tail plug 7 of the intermediate rod 3. Then, a space P through which the fishing line can pass is formed between the projection 52 and the tail plug 7 of the intermediate rod 3 when it comes into contact.

As described above, the intermediate rod 3 can be fitted with the rear part in the mating portion 45 at the front of the upper rod 2 when used, and the upper rod when stored. 2 can be stored inside. Further, a thread insertion path is formed inside. The tail plug 7 of the intermediate rod 3 is a substantially cylindrical member as shown in FIG.
a, 56b are fitted. The inner diameter of the hard ring 56a is larger than the inner diameter of the hard ring 56b. Further, a fitting concave portion 57 having a diameter larger than that of the through hole 55 is formed in front of a portion where the hard ring 56b is fitted. The fitting recess 57 has the same inner diameter over the front and rear.
A male screw portion 58 that is screwed into a female screw portion formed at the rear end of the intermediate rod 3 is formed on the outer peripheral surface of substantially the front half portion of the tail plug 7. In use, as shown in FIG. 6, the rear end face of the buttocks 7 is located behind the front edge of the thread introduction hole 13 of the upper rod 2.

[Front Rod and its Butt Plug] The front rod 4 can be fitted to the front part of the middle rod 3 at the time of use, and the top rod 15 except for the top guide 15 at the time of storage. It can be stored inside. Further, a thread insertion path is formed inside. As shown in FIG. 4, the tail plug 8 of the tip rod 4 is a substantially cylindrical member, and hard rings 61 a and 61 b are fitted into both ends of an inner through hole 60. At the rear of the tail plug 8, there is provided a tapered fitting projection 62 whose diameter becomes smaller toward the rear. A knurl is machined on the outer peripheral surface of the fitting projection 62,
A plurality of grooves along the axial direction are formed at predetermined intervals in the circumferential direction. Then, the fitting protrusion 62 fits inside the fitting recess 57 of the buttocks of the intermediate rod 3. For this reason, the tail plug 7 and the tail plug 8 are fitted in the housed state, so that the intermediate rod 3 and the tip rod 4 are fixed. On the outer peripheral surface on the front side of the buttocks 8, a male screw portion 63 is formed which is screwed into a female screw portion formed at the rear end of the spike rod 4.

[Top Guide] As shown in FIG. 8, the top guide 15 has a widening shape and is fitted and fixed to the outer peripheral surface at the tip of the tip rod 4. A hard ring 70 is fitted on the tip of the top guide 15, and a hard ring 71 having a smaller diameter is fitted on the tip of the tip rod 4.

When the fishing rod is retracted from the use state shown in FIG. 1 to the storage state shown in FIG. Store inside. When the tip rod 4 is stored in the intermediate rod 3, the tail plug 8 of the tip rod 4 fits into the tail plug 7 of the intermediate rod 3,
The two rods 4 and 3 are fixed. Here, the fitting convex portion 62 of the buttocks 8 is fitted into the fitting concave portion 57 of the buttocks 7, but the fitting convex portion 62 is tapered and has knurls. Since 57 has a straight cylindrical shape, the area in which it is in close contact is suppressed. In this way, it is possible to prevent the two from being difficult to come off while fitted.

Next, when the intermediate rod 3 is stored in the upper rod 2 in this state, the rear end of the tail plug 7 of the intermediate rod 3 comes into contact with the projection 52 at the tip of the tail plug 6 of the upper rod 2, and the space P Is secured. At the time of storage, the fishing line extends from the line introduction hole 13 along the outer periphery of the intermediate rod 3 to the tail plug 7, where the fishing line is folded and enters the line insertion path of the intermediate rod 3. At this time, since the space P is formed behind the buttocks 7 by the projections 52, the fishing line is not stepped on the rod buttocks of the intermediate rod 3 and is not damaged. Therefore, the fishing rod can be stowed with the fishing line attached with confidence.

Further, the former rod 2 is housed inside the former rod 1. In this case, the tail plug 6 of the former rod 2 is fitted to the tail plug 5 of the former rod 1, thereby fixing the former rod 2 and the former rod 1.
Here, since the former rod 2 is fixed to the former rod 1 by fitting, the former rod 1 falls out of the former rod 2 even if the intermediate rod is held with the former rod 2 in a stored state. Never.

The fitting of each rod body is performed with a butt plug.
For this reason, only the fitting part of the buttocks needs to be processed with high accuracy, and it is not necessary to strictly control the outer diameter and the inner diameter of the rod body as in the related art. Therefore, the processing is simple and the manufacturing cost is low. FIG. 6 shows a state in the middle of this storage.
Since the hard ring 40b on the front side of the yarn introduction guide 14 is mounted so as to be located forward of the rear end edge of the yarn introduction hole 13, the hard ring 40b and the yarn introduction hole 13 Sufficient space is secured between the rear edge. Further, since the vicinity of the rear end edge of the yarn introduction hole 13 is a relief portion 46, a gap between the inner peripheral surface of the former upper rod 2 and the outer peripheral surface of the intermediate rod 3 is large. Further, the lower end of the hard ring 40 b is located further inward than the outer peripheral surface of the former upper rod 2. For this reason, at the time of storage, thread biting between the rear end edge of the thread introduction hole 13 and the outer peripheral surface of the intermediate rod 3 is unlikely to occur.
Also, the fishing line is folded back by the hard ring 40b,
Since it is difficult to contact the rear end of the yarn introduction hole 13, the yarn introduction hole 1
(3) Thread breakage due to contact at the trailing edge is unlikely to occur.

[At the time of extension of the rod] In order to change the inside rod from the stored state to the used state, the rod body on the tip side is pulled out from the inside of the rod body on the rod base side, contrary to the previous storage state. Then, the rear part of the rod body on the tip side is fitted to the mating part on the rod base side. During this extension,
When the intermediate rod 3 and the former rod 2 are fitted, the stepped portion 47 of the former rod 2 is formed further forward than the front end edge of the yarn introduction hole 13, so that the outer peripheral surface of the intermediate rod 3 A sufficient gap is secured between the leading end of the introduction hole 13 and the fishing line, and it is difficult for the fishing line to bite in this portion.

[At the time of threading] When the fishing line is passed through the inside rod, as shown in FIGS. 2 and 6, the tip rod 4 is housed in the intermediate rod 3, and the two are fitted and fixed together. Is fitted to the mating portion 45 of the upper rod 2. In this state, the rear end face of the tail plug 7 of the intermediate rod 3 is located behind the front edge of the thread introduction hole 13. Therefore, the line insertion path at the rear end of the intermediate rod 3 can be easily confirmed from the line introduction hole 13, and the fishing line can be easily passed through the rod using a liner. Also, since the tip rod 4 is fixed to the intermediate rod 3 by fitting the butt plugs, the intermediate rod 3 is moved to the tip rod 4 during threading.
Can be prevented from jumping out, and threading can be easily performed.

[In Use] In the use state shown in FIG. 1, when casting by swinging the through rod, the fishing line is moved from the hard ring 40a having a large inner diameter to the hard ring 40a having a small inner diameter in the introduction pipe 31 of the line introduction guide 14. It is guided by 40b and introduced into the yarn introduction hole 13. For this reason, the fishing line with the curl immediately after being drawn out can be converged linearly stepwise from a circle, and the resistance at the time of release is reduced.
Therefore, the flight distance is improved.

[Disassembly] When disassembling the through rod,
First, the thread introduction guide 14 is removed. In this case, the fixing bolt 37 is removed using a coin or the like. Then, the introduction pipe 31 becomes detachable, and the mounting part 30 becomes movable in the axial direction. Then, the introduction pipe 31 is withdrawn to some extent or entirely, and the hard ring 40 at the tip of the introduction pipe 31 is pulled out.
b is not caught in the yarn introduction hole 13. In this state, the thread introduction guide 14 is removed from the pole tip side. next,
The tail plugs 6 to 8 are sequentially removed from the tail plug 5 of the original rod 1, and each rod body is sequentially pulled out from the tail plug side. As a result, all the rods can be disassembled, and dirt and the like inside can be reliably removed.

Further, even if the fishing line path is changed by changing the reel, for example, the position of the line introduction guide 14 can be adjusted in the axial direction. The fishing line can always be introduced in an optimal state. For this reason, the contact resistance at the time of feeding the fishing line can be reduced. [Other Embodiments] In the above-described embodiment, the present invention is applied to a four-joint through-type through rod, but the present invention can be similarly applied to two or more through-hole through rods.

[0030]

As described above, according to the present invention, a fitting portion is provided at the rod tip side end of the inner peripheral portion of the outer rod body, and the inner diameter is located closer to the base of the rod than in the penetrating type through rod. Is provided, so that the fishing line does not easily bite when the rod is extended or contracted.
