Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention attaches a small-diameter rod body to the large-diameter rod body in a retractable manner, and provides a fitting mechanism that restricts the movement of the small-diameter rod body with respect to the large-diameter rod body even in the expanded / contracted state. The present invention relates to a multi-stage telescopic swing rod in which a plurality of rod bodies are configured to be stretchable.

[0002]

[Prior art]

 In this kind of multi-stage telescopic rod, a large-diameter bulge is formed on the outer peripheral surface of the tip of the smallest-diameter rod body to form the fitting mechanism. It is constructed so that only the inner peripheral surface of the tip of the diameter rod body is fitted and fixed, and a large diameter bulge is formed on the outer peripheral surface of the tip of this intermediate diameter rod body. The maximum diameter rod body was fitted and fixed only on the inner peripheral surface of the tip (for example, Japanese Utility Model Laid-Open No. 58-26861).

[0003]

[Problems to be solved by the device]

 In this way, when a large-diameter bulge is formed on the outer peripheral surface of the tip at every stage of the small-diameter rod body and the medium-diameter rod body, the diameter of the large-diameter rod body is increased by the thickness of the large-diameter bulge portion. It is difficult to handle because it becomes heavy and heavy, and especially with a long rod such as an ayu rod, it is difficult to handle. An object of the present invention is to provide a rod whose diameter and weight can be reduced by reasonably setting the fitting mechanism.

[0004]

[Means for Solving the Problems]

 The characteristic configuration according to the present invention is that the large diameter bulging portion is formed on the outer peripheral surface of the tip portion of the rod body having the smallest diameter among the above-mentioned telescopic rods, and the rod body having the maximum diameter is formed in the large diameter bulging portion. A large-diameter fitting part that fits and fixes the inner peripheral surface of the tip end part and a small-diameter fitting part that fits and fixes the tip part of each small-diameter rod body on the rod butt side of the large-diameter fitting part are formed. The effect is as follows.

[0005]

[Action]

 That is, in order to switch from the contracted state to the extended state, the rod body with the smallest diameter is pulled out. Then, the rod having the smallest diameter and the next small-diameter rod body fitted and fixed in the small-diameter fitting portion of the large-diameter bulging portion are also integrally drawn. Depending on the number of extension stages, there may be a plurality of small rods that are pulled out. If the rod body with the smallest diameter is pulled out from the extension operation of the first step, the extension operation of the second step can be performed. In this way, every time the rod body with the smallest diameter is pulled out, the rod body with the smaller diameter is drawn out from the rod body with the largest diameter, and the extension operation can be performed. In this way, by forming the fitting portion for fitting and fixing all the rod bodies having a diameter larger than the rod body having the smallest diameter on the large diameter bulging portion of the outer peripheral surface of the rod body having the smallest diameter, the rod body having the smallest diameter is formed. It is not necessary to form a large-diameter bulge on each rod having a larger diameter, and the inner diameter of the larger-diameter rod can be smaller than that of the smallest-diameter rod.

[0006]

[Effect of device]

 As a result, the diameter of each rod body can be reduced, and the weight can be reduced, and accordingly, the rod can be easily handled during actual fishing.

【Example】

 As shown in FIG. 1, a tackle 2 is attached to the tip of the tip rod 1, and a base rod 3 as a large diameter rod body, a base 4 as a small diameter rod body stored in the base rod 3, and a base 4 The upper part 5 as the minimum diameter rod body accommodated in the upper part is constructed so that it can be expanded and contracted to form a fishing rod which can be expanded and contracted in two stages. Next, the expansion / contraction operation structure will be described. As shown in FIG. 1, a butt ring 6 is fixed to the rear end of the base rod 3, a butt plug 7 is screwed to the butt ring 6, and the inner surface of the butt ring 6 is fitted with a rubber fitting. A ring 8 is attached. On the other hand, the upper part 5 stored in the main rod 3 will be described. A front large-diameter bulge portion 9 is formed on the outer peripheral surface of the tip of the upper base 5, and a rear large-diameter bulge portion 10 is formed at the rear end. The maximum diameter portion of the front large-diameter bulging 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 base rod 3, and the tip of the original 4 is located rearward of the large-diameter fitting portion 9A. A small-diameter fitting portion 9B that fits with the inner peripheral surface is formed. The rear large-diameter bulging portion 10 is internally fitted to the fitting ring 8 mounted on the base rod 3 and the fitting ring 11 mounted on the inner peripheral surface of the rear end of the base 4 to form the base 5 Is fitted and fixed to the base rod 3, and the base 4 is fitted and fixed to the base rod 5. With the above configuration, when the upper body 5 is pulled out by holding the tip of the upper body 5 from the state shown in FIG. 1, the upper body 5 and the upper body 4 fitted and fixed to the upper body 5 are integrally pulled out. As shown in FIG. 2, the rear end bulging portion 4A of the base 4 is fitted in the tip inner peripheral surface of the base rod 3 to maintain the extended state. Then, from the state shown in FIG. 2, when the upper body 5 is pulled out with the tip of the upper body 5 and the upper body 4, as shown in FIG. By internally fitting the inner peripheral surface of the tip portion of the upper portion 4, the upper portion 5 of the upper portion can be put into an expanded state, and thus the expansion and contraction operation can be performed in two steps. In this way, the expansion and contraction operation can be performed in two steps, but the fitting structure is such that the large-diameter fitting portion 9A and the small-diameter fitting portion are fitted to the front large-diameter bulging portion 9 formed on the outer peripheral surface of the tip of the upper part 5. By forming the joint 9B, it is possible to contribute to the reduction in diameter and weight of the base rod 3, as shown in the section of the action. 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 surfaces of the tips of the upper rod 4 and the rod 3 which are fitted to these, and The rear large-diameter bulge portion 10 of the upper 5, the fitting ring 8 of the base rod 3 and the fitting ring 11 of the base 4 that fit into the rear large-diameter bulge portion 10 are collectively referred to as the small-diameter rod. A fitting mechanism that regulates the movement of the body with respect to the large-diameter rod body.

[Other Embodiments] In the above-mentioned configuration, the configuration in which the expansion and contraction is performed in two steps is shown, but the expansion and contraction may be performed in three steps. In this case, as shown in FIG. 4, as the shape of the front large diameter bulging portion 9, large, medium and small fitting portions 9A, 9C and 9B are formed to reduce the diameter of the base rod 3. As shown in FIG. 5, the front large-diameter bulging portion 9 formed on the minimum diameter rod body as a structure that expands and contracts in three stages has a large-diameter fitting portion on the front large-diameter bulging portion 9. 9A and a small-diameter fitting portion 9B are formed, and a large-diameter rod body is fitted and fixed to the large-diameter side 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 tip portion of the side rod body, and the large-diameter bulging portion 12 may be fitted to the inner peripheral surface of the tip of the large-diameter rod body.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
