Abstract

(57) [Summary] [Purpose] In the spigot joint fishing rod, the joint part can be attached and detached quickly and easily and the spigot is prevented from being damaged. [Structure] A reinforcing cover cylinder 3 is provided so as to project toward the other rod tube 2 on the outer side of the joint portion of one rod tube 1 joined by a spigot joint, and the inner peripheral surface of the reinforcing cover tube 3 and the rod tube 2 A minute void 6 is formed in the circumferential direction between the outer peripheral surface and the joint portion, and when the load is not applied, the reinforcing cover tube 3 does not adhere to the outer peripheral surface of the rod tube 2 so that the attaching / detaching operation is facilitated. When the joint portion bends more than a certain amount, the reinforcing cover cylinder 3 abuts the outer peripheral surface of the rod tube 2 to prevent the joint portion from further bending and prevent the spigot 4 from being damaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a splicing portion of a spigot joint fishing rod.

[0002]

[Prior Art]

 As a method of strengthening the splicing part of the spigot splicing rod, it is necessary to screw a screw tube to the splicing part and tighten and fix the splicing part to prevent breakage and entanglement. No. 113969.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned method has a problem that the joint portion becomes large and the bending of the fishing rod becomes irregular so that the joint portion cannot be smoothly bent, and the attaching / detaching operation of the joint portion is troublesome and quick and easy. It is an object of the present invention to provide a spigot splicing rod which is improved in such a defect and can be quickly and easily attached / detached with a simple structure while reinforcing the strength.

[0004]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, in a fishing rod in which front and rear rod pipes are spliced with a spigot joint, a reinforcing cover pipe is projected outside the joint portion of one rod pipe toward the other rod pipe. At the same time, a gap is formed in the circumferential direction between the inner peripheral surface of the reinforcing cover cylinder of the projecting portion and the outer peripheral surface of the other rod tube.

The reinforcing cover cylinder may be projected on the rod pipe into which the spigot is inserted, or may be projected on the rod pipe to which the spigot is fixed. In addition, if micro-notches are formed at the inner peripheral edges of the opposing ends of the rod pipes before and after joining, and one of them is filled with a soft cushioning material, the shearing force will be mitigated when the joining part bends. It is possible and preferable.

[0006]

[Operation] When the spigot joint portion of the fishing rod bends, and the deflection becomes large, the reinforcing cover tube in the void portion abuts the outer peripheral surface of the rod pipe inside thereof and prevents further bending of the joint portion, and While it is possible to prevent damage to the rod, the attachment / detachment operation is performed with the reinforcing cover tube not tightly fitted to the outer peripheral surface of the rod tube.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A reinforcing cover cylinder 3 made of metal or the like is provided on the outer side of the tip of the base rod 1 toward the rear end of the rod pipe 2 and the rod pipe 2 A spigot 4 which is fitted in the original rod tube 1 is fixedly adhered inside the rear end, and a reinforcing ring 5 made of metal or the like is fitted on the outer peripheral surface of the rear end of the rod tube 2. A minute gap 6 is formed in the circumferential direction between the outer peripheral surface of the groove 5 and the inner peripheral surface of the reinforcing cover cylinder 3.

Since the embodiment of the present invention is configured as described above, the spigot joint portion bends, and when the deflection increases, the inner peripheral surface of the reinforcing cover cylinder 3 of the cavity 6 becomes the outer peripheral surface of the rod tube 2. While contacting prevents further bending of the splice part to prevent damage to the spigot 4, the splice part of the splice part 2 is not attached tightly to the outer peripheral surface of the rod pipe 2 so that the splice part can be attached and detached smoothly. Can be done.

In the embodiment shown in FIG. 3, minute notches 7 are formed in the inner peripheral edge portions of the opposing ends of the base rod 1 and the rod pipe 2, respectively, and a soft synthetic resin is further provided in the notch 7 of the rod pipe 2. A cushioning material 8 such as hard rubber is filled to prevent the shearing force from being concentrated when the spigot 4 is bent.

[0010]

[Effect of the device]

 According to the present invention, the reinforcing cover tube protruding from the rod pipe is fitted and not closely attached to the outer peripheral surface of the other rod pipe through the gap when no load is applied, so that the attaching / detaching operation of the spigot joint is easy and smooth. In addition, when the deflection of the fishing rod is within a certain load range, the fishing rod can be flexed smoothly without hindering the deflection of the fishing rod. The inner peripheral surface of the cover tube contacts the outer peripheral surface of the other rod tube to prevent further bending of the joint and prevent damage to the spigot. Moreover, it is possible to provide a high strength spigot joint fishing rod.
