Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a connecting structure for connecting rod bodies of a fishing rod.

[0002]

2. Description of the Related Art A fishing rod used for fishing is one fishing rod formed by connecting a plurality of tapered cylindrical rod bodies made of a material such as fiber reinforced resin. There are various possible connection methods for connecting multiple rod bodies, but in the case of a connecting type fishing rod that is generally called a swing type, a small diameter that can be inserted in and out of this large diameter rod body at the tip side of the large diameter rod body The rod body is connected. And, at the time of storage, the small diameter rod body on the tip side is sequentially stored in the large diameter rod body on the rod side to be in a compact state. It is used as one fishing rod by fitting and connecting it to the rod-side outer peripheral surface of the small-diameter rod body.

[0003]

As a problem that occurs when connecting rod bodies to each other by such a swing-out method, wear and abrasion due to contact between the tip side edge of the large diameter rod body and the outer peripheral surface of the small diameter rod body
The damage is mentioned. That is, when the rod bodies are connected to each other by the swing-out method, the small-diameter rod body is inserted into and removed from the large-diameter rod body. At this time, since each rod is a tapered cylindrical body, the tip end side edge of the large-diameter rod and the outer peripheral surface of the small-diameter rod make contact when the small-diameter rod is put in and out of the large-diameter rod. It does. In particular, in today's rod bodies made of fiber-reinforced resin in which reinforcing fibers such as carbon fibers and glass fibers are impregnated with synthetic resin, mutual wear occurs when the end face of the rod body and the peripheral surface of other rod bodies come into contact with each other.・ It is severely damaged.

Such contact between the large-diameter rod body and the small-diameter rod body not only impairs the smoothness of putting the small-diameter rod body into and out of the large-diameter rod body, but also peels off the surface coating of the outer peripheral surface of the small-diameter rod body. This will impair the design and durability of the small diameter rod. An object of the present invention is to provide a rod body connection structure that can smoothly perform connection work and can prevent wear damage and the like.

The connecting structure of the invention 1 is a connecting structure for connecting a plurality of tapered cylindrical rod bodies in a swinging manner, and has a fitting female portion on the inner peripheral surface of the tip side. A small-diameter rod having a large-diameter rod body and a fitting male portion that can be inserted into the large-diameter rod body on the tip side of the large-diameter rod body so that it can be inserted into the mating female portion of the large-diameter rod body. It connects the body.

[0006] A cylindrical member with a lid having a tip-side bottom surface, which has an opening into which a small-diameter rod body can be inserted, and which is large when the large-diameter rod body is inserted from the rod base side. A fixing member that is fixed to the tip side of the diameter rod body, and is arranged so as to be sandwiched between the bottom side of the tip side and the tip side end surface of the large diameter rod body inside the fixing member, and the diameter is smaller than the inner diameter of the opening of the fixing member. And a ring member having an inner diameter of.

In a fishing rod adopting this fitting structure, a large-diameter rod body located on the rod-base side is successively withdrawn and a small-diameter rod body located on the tip side is connected to be used as one fishing rod (specifically, , The rod-side fitting male part of the small-diameter rod body is connected to the female part on the tip side of the large-diameter rod body to connect and fix it. The rod body is sequentially inserted into the large-diameter rod body on the base side of the rod. In this way, when the small-diameter rod body is taken in and out of the large-diameter rod body, the ring member arranged in the fixing member comes into contact with the peripheral surface of the small-diameter rod body to cause “blur” of the small-diameter rod body.
To prevent contact between the tip end side edge of the large-diameter rod body and the outer peripheral surface of the small-diameter rod body. Further, since the fixing member arranges the ring member therein and fixes the ring member to the large-diameter rod body, it is possible to use even a ring member which is difficult to be adhesively fixed.

The connection structure according to the second aspect of the present invention is the structure according to the present invention, wherein the large-diameter rod body further includes a male screw member arranged at the tip end side portion. The inner peripheral surface of the rod-side end of the fixing member is a female screw portion, and the fixing member is detachably attached to the large-diameter rod body. In this structure, the fixing member can be freely attached to and detached from the large-diameter rod body, and by detaching the fixing member, the ring member inside can be replaced.

The connection structure of the invention 3 is the structure of the invention 1 or 2, wherein the ring member is a hard member such as fluororesin, Duracon, or ceramics.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings. The fishing rod adopting the first embodiment of the present invention is, as shown in FIG. 1, a base rod 1 and a base rod 2, a middle rod 3, 4, a tip rod which are sequentially connected to the tip side of the base rod 1. 5 and 5. Each of these rod bodies is a tapered tubular member made of a prepreg material obtained by impregnating reinforcing fibers such as carbon fibers and glass fibers with a synthetic resin such as epoxy resin. As will be described in detail later, these rod bodies are connected in a so-called swinging manner, and the rod bodies located on the tip side can be housed inside the rod body located on the rod side in sequence.

The base rod 1 has a reel seat 8 on the peripheral surface of the rod base side on which the reel 7 can be detachably mounted, and the base rod 2 is provided for introducing the fishing line L from the reel 7 into the rod body. The fishing line introducing port 9 is formed, and the fishing line introducing guide G is arranged on the fishing line introducing port 9. On the other hand, the top guide 6 is arranged at the tip side end of the tip rod 5. Then, the fishing line L from the reel 7 is introduced into the rod body through the fishing line introducing port 9, is sequentially sent to the tip side, and is led out from the top guide 6.

Next, the connecting portion between the rod bodies will be described by taking the upper rod 2 and the middle rod 3 as an example. Although the following description will be made with the base rod 2 and the middle rod 3, the same structure can be adopted for the connecting portion between the other rod bodies. As shown in FIGS. 2 and 3, each of the upper rod 2 and the middle rod 3 is a tubular member that is tapered. The rod base side end of the middle rod 3 is a fitting male portion 3a that is partially processed to have a larger diameter than other parts, and is fitted when the middle rod 3 is pulled out to the tip end side of the upper rod 2. The mating part 3a is fitted to the fitting female part on the inner peripheral surface of the tip end side end of the base rod 2.

A fixing member 10 is arranged at the tip end of the upper rod 2 and a ring member 11 is arranged in the fixing member 10. The fixing member 10 is a cylindrical member with a lid having a bottom on the tip side and is made of hard synthetic resin or metal. An opening through which the middle rod 3 can be inserted is formed in the bottom side of the tip side, and is bonded and fixed to the outer peripheral surface of the top side of the base rod 2 with an adhesive or the like in a state where the base rod 2 is inserted from the base side. .

On the other hand, the ring member 11 is fixed in the fixing member 10 so as to be sandwiched between the bottom surface on the tip side and the end surface on the tip side of the top rod 2. The ring member 11 is a hard member made of, for example, ceramics, Duracon, or fluororesin. The inner diameter is set to be smaller than the inner diameter of the opening of the fixing member 10 and larger than the maximum outer diameter of the middle rod 3 excluding the fitting male portion. The inner peripheral surface of the ring of the ring member 11 is preferably chamfered or the like to be processed into a smooth shape.

When using such a fishing rod, the tip rod 5 is used.
From the above, each rod body is sequentially drawn to the tip side and connected to be used as a single fishing rod. Conversely, when the rod body is stored, it is inserted into the rod body on the rod base side sequentially from the tip rod 5 to make a compact state. In this way, when putting the rod body on the tip side in and out of the rod body on the rod side,
For example, referring to the above-mentioned main rod 2 and middle rod 3, the ring member 11 arranged in the fixing member 10 abuts on the peripheral surface of the middle rod 3 and moves in the circumferential direction of the middle rod 3. Regulate the "blur" of. Then, the tip end side edge of the upper rod 2 and the outer peripheral surface of the middle rod 3 are prevented from contacting each other to prevent damage and wear between the rod bodies. In particular, since the fixing member 10 arranges the ring member 11 therein and fixes the ring member 11, it is possible to use even the ring member 11 made of Duracon or the like, which is difficult to adhere and fix.

[Other Embodiments] (a) As shown in FIG. 4, a male screw member 22 is attached to the outer peripheral surface of the tip end side of the upper rod 2, and the fixing member 20 is detachably screwed thereto. It is also possible to have a structure. The male screw member 22 is a pipe-shaped member having a thread formed on the outer peripheral surface thereof, and is fixed to the outer peripheral edge of the tip side end of the base rod 2 with an adhesive or the like. In addition to separately using such a male screw member, a method of directly cutting a screw thread on the outer peripheral surface of the upper rod 2 can be considered. Then, a fixing member 20 having an internal thread portion that is screwed into the external thread member 22 is prepared on the inner peripheral surface of the rod-side end portion, and the ring member 21 is interposed on the inner periphery thereof.
