Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod in which a plug engaged with an end of a rod tube is prevented from coming off.

[0002]

2. Description of the Related Art Conventionally, when a plug is engaged with the end of a rod tube, a recess is formed on the inner surface of the original rod and an engaging piece is attached to the plug body as disclosed in, for example, Japanese Utility Model Laid-Open No. 3-105275. It is known that a screw body is screwed into the plug body and the plug body is fitted to the inner surface of the main rod, and the engagement piece is engaged with the recess by screwing the screw body. In the above structure, when the threaded body is screwed to engage the engaging piece with the recess, if the engagement between the main rod and the plug body is loose, the screw body is rotated and the plug body is rotated. In addition, there is a drawback that it is difficult to operate because the engaging operation cannot be performed unless the screw body is screwed while the main rod and the plug body are both held and fixed by the hand. On the contrary, if the base rod and the plug body are tightly fitted to each other, it is difficult to align the engaging piece with the recess, and unstable engagement is likely to occur. Further, since the engagement is fixed by screwing the screw body, the number of rotations of the screw body until the engagement is fixed is increased, and it is difficult and difficult to fix the plug body. Furthermore, it was also troublesome when the plug body was removed from the rod.

[0003]

The problem to be solved is that if the base rod and the plug body are loosely fitted, the plug body is rotated as the screw body is screwed, and the engaging operation becomes difficult. Hard to do,
If the fitting is tight, it is difficult to align the engagement piece and the recessed portion, and unstable engagement is likely to occur, and since the screw body is screwed, the fixing operation is difficult to perform, which is troublesome.

In view of the above-mentioned drawbacks, an object of the present invention is to provide a fishing rod in which the plug body is removably attached to the rod pipe by gripping the rod pipe and switching the operating portion of the operating body.

[0005]

In order to achieve such an object, the present invention relates to a first aspect of the present invention, in which an end portion of a rod tube is formed with a detent portion in the axial direction and is pulled out in the circumferential direction. A stopper is formed, and an operating body provided with an operating section for operating from the outside and a cam mechanism is disposed on the stopper, and a stopper is switchably disposed on the cam mechanism of the operating body. The main feature is that a stopper is formed on the rod tube to prevent rotation, and the stopper is engaged with the retaining portion in a retaining state. is there. In the invention according to claim 2, an operation body is provided in which a retaining portion is formed in a circumferential direction at an end portion of the rod tube, and an operation portion for operating from the outside and a switching mechanism for switching a stopper are provided in the plug body. In addition, the stopper is provided with a pressing member such as a spring that elastically applies a pressing force in the direction of the retaining portion, and the stopper is automatically detached from the retaining portion when the plug is fitted into the rod tube. The gist is that it is engaged in a stopped state.

[0006]

When the operating body 4 and the stopper 5 are assembled in the plug body 3, the short diameter portion of the elliptical recess 4c of the operating body 4 is shown in FIG.
The operation portion 4e is rotated from the vertical direction of the solid line to the horizontal direction of the two-dot chain line. The tongue piece 5b of the stopper 5 is inserted into the inner peripheral elliptical recess 4c of the operating body 4, and the rectangular portion 5a of the stopper 5 is inserted into the through hole 3e of the stopper 3. Next, when the plug body 3 is incorporated into the rod tube 1, the restricting portion 3d of the plug body 3 is fitted to the rotation stopping portion 1a of the rod tube 1 and inserted. After that, when the elliptical concave portion 4c is rotated by 90 ° in the vertical direction in the operation portion 4e from the horizontal direction of the two-dot chain line in FIG. 2 as shown by the solid line, the major axis portion of the elliptical concave portion 4c is vertically rotated. The portion 5a is engaged with the retaining portion 1b of the rod tube 1 and is retained. When the plug body 3 is detached from the rod tube 1, when the operating portion 4e of the operating body 4 is rotated by grasping the rod tube 1, the stopper 5 is detached from the retaining portion 1b of the rod tube 1. Can be removed.

In the above description, the plug body is fitted to the rear end portion of the rod tube 1 to prevent the rod tube from coming off. However, the plug body is detachably attached to the front end portion of the rod tube 1. You may

[0024]

Since the present invention is constructed as described above,
Since the plug body is prevented from rotating on the rod tube, the cam mechanism pushes up the stopper and engages with the retaining portion of the rod tube in a retaining state by the switching operation in which the operating portion is rotated by gripping the rod tube. Therefore, the stopper can be easily attached to the rod tube by one-touch operation or automatically. Further, when the plug body is detached from the rod tube, when the operating portion of the operating body is rotated by grasping the rod tube, the stopper-
Is detached from the retaining part of the rod tube and can be easily and easily removed by one-touch operation. Further, since the stopper is engaged with the rod tube to prevent the stopper from coming off, it is possible to provide a fishing rod having an excellent effect such that the stopper is reliably prevented from coming off during use of the fishing rod.
