Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of rod bodies of a fishing rod, which is formed by connecting a plurality of rod bodies in a swing manner.

[0002]

2. Description of the Related Art A conventional swing-out type fishing rod has a large-diameter rod body having an inner circumference at the tip end side as a fitting female portion and a large-diameter rod body having an outer circumference at the base end as a fitting male portion. And a small diameter rod body connected to. In this swing-out type fishing rod, a small-diameter rod body is inserted into the large-diameter rod body from the tip side so that it can be freely taken in and out. Then, when fishing, each rod body is sequentially pulled out to the tip side, fitted and fixed, and used as one rod body. on the other hand,
At the time of storage, the rod body on the tip side is sequentially stored in the rod body on the base side of the rod to make it compact.

Further, among such swing-type fishing rods, there is one devised so that fishing can be performed by changing the length of the entire rod. The original rod (large diameter rod body) of the fishing rod devised in this way is formed with a diameter slightly smaller than the other parts on the inner peripheral surface of the tip end side end, and the rod end side of the rod is attached. It has a first fitting and fixing portion that can be fitted and fixed, and a second fitting and fixing portion that is disposed in the rod-base-side end portion and that can fit and fix the rod-base-side end portion of the upper rod. The state in which the original upper rod connected to the tip side of the original rod is pulled out to the tip side (hereinafter referred to as "extended state")
And the state that the original rod is inserted in the original rod (hereinafter "storage state"
That is, the upper rod is fitted and fixed to the first fitting fixing portion and the second fitting fixing portion, respectively. In this way, the base rod and the base rod can be fitted and fixed to each other in any of the "stretched state" and the "stored state", and fishing can be performed by changing the entire length of the rod depending on the situation.

[0004]

In the conventional swing-out type fishing rod, when the inner rod body is put in and out of the large diameter rod body, the air in and out of the large diameter rod body is bad, and the small diameter rod body can be smoothly inserted and pulled out. It may not be possible. This is because the space for accommodating the small-diameter rod body in the large-diameter rod body is closed by the large-diameter rod body, the small-diameter rod body, and the buttocks attached to each rod body, so that it is closed. Moreover, air resistance is generated like the piston and cylinder, and the small diameter rod body cannot be smoothly taken in and out.

Such a phenomenon may occur when a small-diameter rod body is taken in and out of the large-diameter rod body even during fishing, "a fishing rod devised so that fishing can be performed by changing the length of the entire rod".
In particular, inconvenience tends to occur. In addition, in a hollow fishing rod in which the fishing line is inserted through the inside of the rod body, water may enter the inside of the rod body together with the fishing line, and it may be necessary to drain the water. In such a case, it is complicated to disassemble the rod bodies that are connected one by one and shake the individual rod bodies vigorously to drain the water inside.

[0006] An object of the present invention is to provide a rod body connecting structure for facilitating withdrawal or connection of the rod body.
Another object of the present invention is to provide a rod connecting structure capable of easily draining water that enters the inside of the rod.

[0007]

A connecting structure according to the first aspect of the present invention is a structure for connecting rod bodies to each other in a swinging manner, wherein an inner peripheral surface of a tip end is a fitting female portion. The rod base side rod body having a groove provided through in the axial direction, and is connected to the tip side of the rod base side rod body so that it can be inserted into the rod base side rod body freely, and the rod base side end is more than other parts. In particular, it is a large-diameter part having a large diameter, and the tip end side rod body is a fitting male part whose outer peripheral surface of the large-diameter part is fittable to the fitting female part. Then, when the fitting female part and the fitting male part are fitted, the tip side end of the rod side rod body is positioned so as to project to the tip side from the large diameter portion of the tip side rod body, The side rod body is coated with a water-repellent paint on the tip side peripheral surface of the large diameter portion.

[0008] With this structure, the tip side rod body is inserted into the rod side rod body during storage and is stored in a compact state.
Then, at the time of stretching, the tip side rod body is pulled out from the inside of the rod side rod body, and the fitting male portion of the tip side rod body is fitted and fixed to the fitting female portion of the rod side rod body to be connected. At this time, a groove formed in the fitting female portion of the rod-side rod body provides an air inlet / outlet with respect to a space formed inside the rod-side rod body and capable of accommodating the tip-side rod body. That is, air can always pass through the groove formed in the fitting female portion during the connecting operation of the tip side rod body and the rod side rod body, and the tip side formed inside the rod side rod body The space in which the rod can be stored is no longer close to a closed space. As a result, the tip side rod body can be smoothly taken in and out of the rod side rod body.

If this structure is applied to a so-called hollow fishing rod, the water that has entered inside the rod body together with the fishing line and flows and is flowed to the tip side sequentially when the fishing rod is shaken, and at the connecting portion of the rod body, the fitting female part is formed. The groove formed in will flow as a drain groove. In this way, water accumulated in the rod body can be easily drained. On the contrary, such a groove may also serve as a way for rainwater or drained water to flow into the rod body from the outside. Therefore, in the state of pulling the tip side rod body out of the rod side rod body during stretching, the tip side end of the rod side rod body extending to the tip side of the fitting male part consisting of the large diameter part of the tip side rod body is Like the "eave", it covers the connection between the tip side rod body and the rod side rod body to prevent rainwater from entering. Further, the water-repellent paint applied to the tip side peripheral surface of the fitting male portion repels water accumulated in this portion, thereby suppressing the intrusion of water from the groove.

The connection structure of the invention 2 is a structure for connecting rod bodies in a swinging manner, wherein a rod base side rod body having a fitting female portion on the tip end side inner peripheral surface and a rod base side rod body. It is connected to the tip side of the rod so that it can be inserted freely into the rod-side rod body, and the rod-side end is a large-diameter portion that has a larger diameter than the other parts. It is a fitting male part that can be fitted, and has a tip-side rod body having a groove that is provided through the fitting male part in the axial direction. Then, when the fitting female part and the fitting male part are fitted,
The tip side end of the rod side rod is located so as to project to the tip side from the large diameter part of the tip side rod body, and the tip side rod body is coated with water repellent paint on the tip side peripheral surface of the large diameter part. ing.

In this connection structure, a groove is formed on the fitting male portion side, which is the opposite of the invention 1, and this groove functions as a passage or a drainage path for air. Also here, the tip side end of the rod base side rod body that extends to the tip side of the fitting male part consisting of the large diameter part of the tip side rod body has a tip side rod body and a rod side rod body like an "eave". Covers the connecting part of to prevent rainwater from entering. Further, the water-repellent paint applied to the tip side peripheral surface of the fitting male portion repels water accumulated in this portion, thereby suppressing the intrusion of water from the groove.

[0012] The connecting structure of the invention 3 is the structure of the invention 1 or 2, wherein the tip side rod body or the rod base side rod body is formed with irregularities in the axial direction at the rod base side end or the tip side end. It is formed by winding a fiber reinforced resin around a core material. Here, the core material is provided with irregularities for forming a predetermined groove, and the fiber reinforced resin is wound around the core material to directly form the groove in the rod body during manufacturing. Thus, the workability is improved by directly providing the groove on the rod body from the time of manufacturing.

It is set to match the inner diameter of. Then, when the base rod 2 is pulled out from the base rod 1, this large-diameter portion is fitted to the tip-side inner peripheral surface of the base rod 1, so that the base rod 2 and the base rod 1 are in the “extended state”. Can be locked. In this way, when the base rod 2 and the base rod 1 are locked in the "stretched state", the tip side end of the base rod 1 extends beyond the large diameter portion of the base rod 2 toward the tip side. The eaves are designed to completely cover the large diameter part inside the rod 1.

A plurality of grooves 2a are formed in the large diameter portion of the base rod 2 at intervals in the circumferential direction. The groove 2a is formed so as to penetrate the large diameter portion in the axial direction, and serves as a communication passage that connects the inside and the outside of the base rod 1. The depth of the groove 2a is about 0.5 to 1.0 mm, and it is possible to provide the base rod 1 by cutting the inner peripheral surface after molding. In addition, the peripheral surface of a fixed area in the axial direction on the tip side of the large diameter portion of the base rod 2 (Fig. 3

[Second Embodiment] A second embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 5 and 6, a plurality of grooves 1a are formed at intervals in the circumferential direction on the inner peripheral surface of the tip end side end of the base rod 1 of the fishing rod adopting the second embodiment of the present invention. There is. The tip end side inner peripheral surface of the base rod 1 is a fitting female part that fits with the fitting male part of the rod base side end of the base rod 2, and the groove 1a is longer than the axial length of the fitting male part. It is also long and is formed by continuously extending in the axial direction from the tip side end surface of the base rod 1. Further, the tip side end of the base rod 1 is located so as to extend toward the tip side from the fitting male portion of the base rod 2 when the base rod 1 is fitted.

The groove 1a of the base rod 1 can be formed by forming the rod body as usual and then cutting the inner surface of the rod body from the tip end side. In addition, in order to reduce the contact area between the fishing line inserted through the inside of the rod body and the inner circumferential surface of the rod, and to smoothly take the fishing line in and out, a spiral protrusion for supporting the fishing line may be formed on the inner circumferential surface of the rod. There is (for example, in the case of Motojo rod 2 etc.). In the rod body in which such a protrusion is formed on the inner peripheral surface, the fitting female portion can be thickened by the height of the protrusion, and the groove 1a can be easily carved deep enough. For example, the height of such a protrusion is 0.
When manufacturing a rod body by setting it to about 3 to 0.4 mm, at least this thickness can be secured at the tip side end that is the fitting female part, and the groove 1a with a depth of about 0.1 to 0.25 mm is formed. You will be able to do it. Furthermore, such a groove 1

It is also possible to directly form the base rod 1 from the time of manufacture by the following method. That is, as shown in FIG. 7, a rod body including the base rod 1 generally has a mandrel 100 having a predetermined taper, in which reinforcing fibers such as carbon fibers and glass fibers are oriented and impregnated with a synthetic resin. The prepared prepreg material is processed into a sheet shape or a tape shape and wound, and these are fired to be manufactured. Here, a predetermined groove 1a is formed by forming irregularities in the axial direction on the tip side end of the mandrel 100 itself, winding the prepreg material while applying pressure, and molding the irregularities. Is also possible. Alternatively, the mandrel 100 may be a separate member made of synthetic resin or metal having a peripheral surface with irregularities.
Alternatively, the prepreg material may be wound around the tip of the mandrel 100 and attached mechanically and wound around the mandrel 100 and the outer periphery of the separate member.

On the other hand, the water repellent paint is applied to the tip end side peripheral surface of the fitting male portion of the base rod 2 as in the first embodiment. Further, the same structure can be adopted for the connecting rods of the middle rod and the tip rod located on the tip side of the base rod 2 as well. Also in the fishing rod configured in this manner, when the base rod 2 and the base rod 1 are expanded and contracted, the groove 1a serves as a communication path between the inside and the outside of the rod body and is a space formed inside the base rod 1. Is no longer close to a closed state, so that the upper rod 2 can be smoothly put in and taken out of the former rod 1.

Further, the water that has entered the rod body is sequentially flowed to the tip side when the fishing rod is shaken, and in the connecting portion of the rod body, the groove 1a flows as a drainage groove. And
The tip side end of the base rod 1 overhangs to the tip side like a “corner” to cover the connecting portion between the top rod 2 and the base rod 1, and rainwater may invade from the groove 1a. Is suppressed. Further, the water-repellent paint applied to the tip side peripheral surface of the large diameter part repels water accumulated in this part (see FIG. 5) to form the groove 1
Prevent water from flowing into the rod from a.
