Description

[Detailed description of the invention]

[0001]

The present invention relates to a fitting for restricting the movement of a small-diameter rod with respect to a large-diameter rod in both expansion and contraction conditions, while attaching a small-diameter rod to a large-diameter rod. The present invention relates to a multi-stage telescopic swing rod provided with a mechanism and configured so that a plurality of rod bodies can be extended and contracted.

[0002]

2. Description of the Related Art In a multi-stage telescopic type swing rod, a large-diameter bulge is formed on the outer peripheral surface of the tip end of a minimum-diameter rod to constitute a fitting mechanism. In addition, only the inner peripheral surface of the tip portion of the next larger intermediate diameter rod body is configured to be fitted and fixed, and a large diameter bulge is formed on the outer peripheral surface of the distal end portion of the intermediate diameter rod body. Further, only the inner peripheral surface of the distal end portion of the largest diameter rod body having a larger diameter is fitted and fixed to the portion (for example, Japanese Utility Model Application Laid-Open No. 58-26861).

[0003]

When a large-diameter bulge is formed on the outer peripheral surface of the distal end portion of each of the small-diameter rod and the medium-diameter rod as described above, the thickness of the large-diameter bulge is increased. The diameter of the diameter rod body increased, the weight also increased, and it was difficult to handle, especially for long rods like ayu rod . The purpose of this invention is
An object of the present invention is to provide a rod that can be reduced in diameter and weight by setting the fitting mechanism rationally.

[0004]

The feature of the present invention is that a large-diameter bulge is formed on the outer peripheral surface of the distal end of the minimum-diameter rod of the telescopic rod described above. A large-diameter fitting portion that fits and fixes the inner peripheral surface of the distal end portion of the rod body having the largest diameter, and a small-diameter fitting that fits and fixes the distal end portion of each small-diameter rod body to the rod tail side from the large-diameter fitting portion. The effect is as follows.

[0005]

[Operation] In other words, in order to switch from the contracted state to the extended state, the rod body having the minimum diameter is pulled out. Then, the next small-diameter rod body fitted and fixed at the small-diameter fitting portion between the minimum-diameter rod body and the large-diameter bulging portion is also integrally pulled out. The small-diameter rod body to be pulled out may be plural depending on the number of extension steps. If the rod body having the minimum diameter is further pulled out than the first-stage extending operation, the second-stage extending operation can be performed. In this way, every time the rod body having the smallest diameter is sequentially pulled out, the rod body having the smaller diameter can be pulled out from the rod body having the largest diameter to perform the extension operation. As described above, the minimum diameter rod body is formed by forming the fitting portion for fitting and fixing all the rod bodies larger in diameter than the minimum diameter rod body in the large diameter bulging portion on the minimum diameter rod body outer peripheral surface. It is not necessary to form a large-diameter bulging portion on each of the rods having a larger diameter, and the inner diameter of the rod having a larger diameter than that of the rod having the smallest diameter can be reduced accordingly.

[0006]

[Effects of the Invention] As a result, the diameter of each rod body can be reduced, and the weight can be reduced.
The handling of the rod during actual fishing can be facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
And the former rod 3 as a large-diameter rod body, the former 4 as a small-diameter rod body stored in the former rod 3, and the former upper 5 as a smallest-diameter rod body stored in the former rod 4 The fishing rod is configured so as to be able to extend and contract and can be extended and contracted in two stages. Next, the telescopic operation structure will be described. As shown in FIG. 1, a tail ring 6 is fixed to the rear end of the original rod 3, a tail plug 7 is screwed to the tail ring 6, and a rubber fitting ring 8 is attached to the inner surface of the tail ring 6. Is attached.
On the other hand, a description will be given of the upper part 5 stored in the former pole 3. A front large-diameter bulge 9 is formed on the outer peripheral surface of the front end of the upper upper part 5 and a rear large-diameter bulge 10 is formed at the rear end. The large-diameter portion of the front large-diameter swelling portion 9 is formed as a large-diameter fitting portion 9A that fits with the inner peripheral surface of the distal end portion of the original rod 3, and the tip of the upper base 4 is located behind the large-diameter fitting portion 9A. Small-diameter fitting portion 9B that fits with the inner peripheral surface
Is formed. The rear large-diameter swelling portion 10 is fitted inside a fitting ring 8 attached to the original rod 3 and a fitting ring 11 attached to the inner peripheral surface of the rear end of the original upper 4. A configuration is adopted in which the base 4 is fitted and fixed to the base pole 3 and the base 4 is fitted and fixed to the base 5. With the above configuration, FIG.
When the user pulls out the upper end of the upper base 5 from the state shown in FIG. 2, the base 4 fitted and fixed to the upper base 5 together with the upper base 5 is integrally pulled out. As shown in FIG. The rear end bulging portion 4A is fitted inside the distal end inner peripheral surface of the original rod 3 and maintains its extended state. Then, from the state shown in FIG. 2, when the upper part 5 of the upper part of the upper part 5 is pulled out with the tip of the upper part 5 of the upper part 5 and the upper part 4 of the upper part of the upper part, as shown in FIG. Top 4
The inner upper surface of the upper end 5 can be in an extended state by being fitted inside the inner peripheral surface of the front end portion, and the expansion and contraction operation can be performed in two stages. As described above, the expansion / contraction operation can be performed in two stages. However, as a fitting structure, the front large-diameter bulging portion 9 formed on the outer peripheral surface of the tip of the upper upper part 5 is used.
By forming the large-diameter fitting portion 9A and the small-diameter fitting portion 9B at the same time, it is possible to contribute to reducing the diameter and weight of the original rod 3 as described in the section of the operation. Here, the large-diameter fitting portion 9A and the small-diameter fitting portion 9B in the front large-diameter bulging portion 9 and the inner peripheral surface of the former 4 and the former rod 3 fitted to these, and furthermore, the upper 5 The rear large-diameter bulging portion 10, the fitting ring 8 of the original rod 3 fitted to the large-diameter bulging portion 10 thereafter, and the fitting ring 11 of
Collectively, it is a fitting mechanism that regulates the movement of the small diameter rod relative to the large diameter rod.

[Alternative Embodiment] In the above-described configuration, the configuration in which the expansion and contraction is performed in two steps has been described. However, the expansion and contraction may be performed in three steps. In this case, as shown in FIG. 4, the shape of the front large-diameter bulging portion 9 is as follows.
The large, medium and small fitting portions 9A, 9C, 9B are formed to reduce the diameter of the original rod 3. As shown in FIG. 5, the front large-diameter bulging portion 9 formed on the minimum diameter rod body as a configuration that expands and contracts in three stages can take a large-diameter fitting portion 9A as shown in FIG. And a small-diameter fitting portion 9B, and a large-diameter side rod body is fitted and fixed to a large-diameter rod body fitted and fixed to the small-diameter fitting portion 9B. A large-diameter bulging portion 12 may be formed on the outer peripheral surface of the distal end portion, and the inner peripheral surface of the distal end of the large-diameter rod may be fitted into the large-diameter bulging portion 12.
