Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering rod having a fishing line passage into which a fishing line from a reel can be inserted.

[0002]

2. Description of the Related Art A conventional fishing rod has a fishing rod having a fishing line passage through which a fishing line can be inserted, a reel fixed to the fishing rod in a detachable manner, and an outer circumferential surface of the fishing rod side of the reel. It has a formed fishing line introduction port. In such a centering rod, the fishing line from the reel is introduced into the fishing line passage from the fishing line introducing port, is sequentially guided into the rod body on the tip side, and the fishing line is led out from the top guide at the tip of the tip rod.

In order to reduce the sliding resistance by reducing the contact area between the fishing line and the inner peripheral surface of the rod when the rod is inserted through the rod body, recently, in order to reduce the sliding resistance, the fishing line passage inside the rod body of the middle fishing rod is recently used. Some fishing lines support projections are formed on the inner peripheral surface so as to project radially inward. The fishing line support protrusion is continuously formed in a spiral shape in the axial direction of the rod body, and supports the fishing line when the fishing line is inserted through the fishing line passage inside the rod body.

[0004]

In such a fishing rod, the fishing line from the reel, especially the spinning reel, is paid out in a spiral shape from the spool. At this time, “line twist” occurs in the fishing line. On the other hand, when the fishing line is wound on the spool, the fishing line is wound in the circumferential direction of the spool by being guided by the bale and the line roller from the axial direction of the spool. It occurs on fishing line. If the same amount of "thread twist" is generated in the opposite directions during such feeding and winding, the "thread twist" will not be offset and remain in the fishing line wound on the spool. Should be.

However, while the fishing line is passing through the fishing line passage inside the rod body, the fishing line support protrusions formed in a spiral shape inside the rod body come into contact with the fishing line, and the fishing line has an extra "line twist". "
May occur. That is, when the fishing line is wound, the fishing line is wound on the spool while tension is applied to the fishing line.
At this time, a force may be applied to the fishing line in the circumferential direction due to the fishing line being wound on a spool or the movement of a fish that has been tackled. . Due to such a runout in the circumferential direction and the contact with the fishing line support protrusion, a bending force or the like is applied to the fishing line, and extra "line twisting" occurs in the fishing line. When such extra "line twist" occurs, the extra "line twist" is gradually accumulated on the fishing line wound around the spool of the reel, which may hinder the smooth feeding of the line.

An object of the present invention is to provide a threading rod capable of preventing the occurrence of "thread twist".

[0007]

According to a first aspect of the present invention, there is provided a fishing rod which allows a fishing line from a reel to be inserted therein.
A tubular member having a fishing line passage inside, a spiral fishing line support projection formed continuously on the inner circumferential surface of the fishing line passage in the axial direction, and a part in the circumferential direction on the inner circumferential surface of the fishing line passage. And a rod body having a groove extending in the axial direction.

With this hollow fishing rod, the fishing line from the reel is guided through the fishing line passage inside the rod body. When the fishing line is paid out, the fishing line is led out in a spiral shape from the reel and reaches the tip side while passing through the fishing line passage. On the other hand, when the fishing line is wound, the fishing line is sequentially wound with tension applied to the fishing line. At this time, the tensioned fishing line receives a force in the circumferential direction in response to the movement of the fish on the tackle, etc., but the fishing line fits in the groove extending in the axial direction of the fishing line passage,
The movement of the fishing line in the circumferential direction is suppressed. As a result, unnecessary "line twisting" is suppressed without applying unnecessary bending force or the like when winding the fishing line.

A second aspect of the invention is a medium-length fishing rod according to the first aspect of the invention, wherein the rod body has a fishing line introducing port for introducing the fishing line from the reel into a fishing line passage inside the rod body, and the groove has a rod. It is formed on the side where the fishing line introducing port is formed in the circumferential direction of the body.

With this hollow fishing rod, when the fishing line is paid out, the fishing line is led out in a spiral form from the reel, is introduced into the rod body from the fishing line introducing port while converging the spiral, and is inserted through the fishing line passage to the tip side. Leading to. On the other hand, when the fishing line is wound, the fishing line is sequentially wound with tension applied to the fishing line. Here, when the fishing line is wound, the fishing line tends to be biased on the side where the fishing line introduction port is formed in the circumferential direction of the rod body, but since the groove is formed in this direction, the fishing line is easily formed. It is possible to effectively suppress the occurrence of "thread twisting" in the groove.

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a centering rod adopting the first embodiment of the present invention includes a base rod 1, a base rod 2 and a base rod 2 connected to the tip side of the base rod 1. It has the middle rods 3 and 4 connected to the tip side, and the tip rod 5 connected to the tip side of the middle rod 4. Each of the base rod 1 to the tip rod 5 is a tapered cylindrical member formed of a prepreg obtained by impregnating carbon fiber, glass fiber or the like with a synthetic resin, and has a fishing line passage therein. And, the upper rod 2 to the tip rod 5 are sequentially inserted into the rod body on the rod base side from the tip side so that they can be freely taken in and out,
They are linked in a so-called drawing format.

The base rod 1 has a reel seat 8 which is formed on the outer peripheral surface thereof and on which a reel 7 can be removably mounted, and a tail plug 10 is removably mounted on an end portion on the base side of the rod. In addition, a fishing line introducing port 9 for introducing the fishing line L from the reel 7 into the rod body is formed on the peripheral surface of the base rod 2 on the tip side, and is arranged so as to cover the fishing line introducing port 9. Fishing line introduction guide 20
Is fixed. The fishing line introducing port 9 of the base rod 2 is an axially long hole formed on the peripheral surface of the base rod 2 on the tip side, and a ring made of synthetic resin, ceramic, or the like is fitted to the periphery thereof. . A fishing line introducing guide 20 is arranged so as to straddle the fishing line introducing port 9 in the axial direction.

On the other hand, as will be described later, a fishing line passage through which the fishing line L introduced from the fishing line introducing port 9 is inserted is formed inside the middle rod 3 to the tip rod 5 and the top guide is provided at the tip end. 6 is attached. Then, the fishing line L from the reel 7 passes through the fishing line introducing guide 20 and the fishing line introducing port 9, is guided to the fishing line passage, and sequentially passes through the insides of the Motogami rod 2 to the tip rod 5 to the top of the tip rod 5 on the tip side. It will be guided from the guide 6 to the outside.

The fishing line passage inside the middle rod 3 to the tip rod 5 through which the fishing line L is inserted will be described by taking the middle rod 3 as an example.
As shown in FIGS. 2 to 6, the inner rod 3 is a tapered tubular member, and the inside thereof is a fishing line passage. On the inner peripheral surface of the middle rod 3, which is the peripheral surface of the fishing line passage, fishing line support projections 30 projecting radially inward are continuously formed in a spiral shape with axial intervals. A groove 31 extending in the axial direction is formed in a part of the inner peripheral surface of the fishing line passage in the circumferential direction.

The fishing line support protrusion 30 is a protrusion integrally formed when the tubular portion of the middle rod 3 is manufactured. For example,
The following methods can be illustrated. The middle rod 3 is manufactured by winding a prepreg sheet or prepreg tape made of a prepreg material around a core material and firing it. At this time, the fishing line support is spirally supported on the outer periphery of the core material while being axially spaced. It is possible to manufacture the inner rod 3 by winding the projection forming tape, winding the tubular portion forming prepreg sheet around the outer periphery thereof, and firing the two to integrate them.

The groove 31 has a width of 0.5 to 3 mm and a depth of 0.
It is a groove of about 2 to 0.5 mm and is continuously formed in the axial direction of the middle rod 3, and is partially described above as the fishing line support protrusion 30.
(See FIG. 6). It is also possible to form the inner rod 3 having the fishing line support projections 30 by the method as described above and then partially cut a part in the circumferential direction. Figure 4
As shown in, the circumferential direction of the upper rod 2 and the middle rod 3 is set so that the circumferential direction in which the fishing line introducing port 9 of the upper rod 2 is positioned and the circumferential direction in which the groove 31 of the middle rod 3 is positioned match. It is preferable to perform alignment, and it is preferable to apply a line mark or the like for circumferential alignment on the outer peripheral surface of the connection portion between the upper rod 2 and the middle rod 3.

The same fishing line passages, fishing line supporting projections, and grooves are formed in the middle rod 4 and the tip rod 5 as well. In the hollow fishing rod configured in this way, the fishing line L from the reel 7 fixed to the peripheral surface of the fishing rod 1 passes through the fishing line introducing guide 20 of the fishing rod 2 from the fishing line introducing port 9 to the fishing rod 2 , And to the fishing line passages of the middle rod 3 to the tip rod 5. Fishing line L
At the time of feeding, the fishing line L is led out from the reel 7 in a spiral shape and gradually converges to reach the fishing line passage from the fishing line introducing port 9. On the other hand, when winding the fishing line L, the fishing line L
The fishing line L is successively wound with the tension applied to the fishing line.

When the fishing line L that has received this tension is inserted through the fishing line passage of each rod body, the fishing line L is wound in the fishing line passage or the bending of the rod body causes the fishing line L to pass through the reel 7 to the fishing line. It is biased to one side in the circumferential direction where the inlet 9 is located. Here, the fishing line L fits into the groove 31 extending in the axial direction in this one circumferential direction, and unnecessary movement in the circumferential direction is suppressed. Therefore, when the fishing line L is wound up, unnecessary bending force and the like are suppressed, and the fishing line L is wound in a stable state in the axial direction. It is possible to prevent the accumulation of “shaking”.

[Other Embodiments] (a) In the above embodiment, the fishing line introducing port 9 is formed in the base rod 2 and the fishing line introducing port 9 is near the tip side of the base rod 2. Although it was a through-rod, the position of the fishing line introducing port 9 and the rod body forming the fishing line introducing port 9 can be arbitrarily set.

For example, when the fishing line introducing port 9 is formed at a position slightly distant from the tip end side end of the base rod 2 toward the rod base side in the axial direction, as shown in FIG. The groove 31 may be formed by forming the fishing line support protrusion 30 on the inner peripheral surface on the side. The groove 31 is provided in the circumferential direction of the upper rod 2 in the direction in which the fishing line introducing port 9 is formed. (B) It is not necessary to provide all the grooves 31 on each rod body, and it may be formed on a specific rod body or only on a part of the specific rod body. For example, it may be provided only on the middle rod 3 or the upper rod 2 which has a large diameter and is located on the rod base side. In the case where the fishing line support projection 30 and the groove 31 are formed on the fishing rod 2, the groove 31 may be formed only in a part near the fishing line introducing port 9.
