Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a fishing rod used for fishing, and more particularly to a telescopic rod that can be easily extended.

[0002]

[Prior art]

 Recently, the fishing boom has increased the fishing population, and the number of people fishing regardless of age or sex is rapidly expanding. Moreover, the number of full-fledged fishing enthusiasts is increasing, and specialized fishing equipment tends to be developed. In particular, rods are particularly important parts for manipulating fishing lines, and rods having various functions are on the market.

By the way, depending on the type of fish, some fishing methods mainly use the pulling-out method rather than the so-called approaching method. Ayu fishing is often carried out in the river or in the river, so the scaffolding is unstable and we are skilled in so-called pulling out.

Therefore, it is important to make it easy to take in the caught fish by the drawing method. In ayu fishing, the length of the fishing line is longer than that of the rod, so when the fish is pulled out, the shorter the difference between the length of the rod and the length of the fishing line, the easier it is to take in. Therefore, a highly functional rod has been developed that can extend the rod length to the same length as the fishing line.

When performing ayu fishing using this extendable fishing rod, first, the rod is set at the reduced position, for example, 9 m, and the tackle is carried out. When a fish is caught, the length of the rod is immediately pulled out to the extended position, for example, 9.3 m, and set at that stage.

Then, the rod held by one hand is raised to pull back the fish. In this case, since the length of the connecting rod is extended and lengthened, the position of the caught fish is raised, and it is extremely easy to take in the fish with a fish basket or the like. An example of such a rod that can be extended is a retractable rod as shown in FIG.

In this rod, the moving rod 1 is extrapolated to the base rod 2, and at the extended position (b), the rod tip of the moving rod and the rod butt of the base rod 2 are temporarily fixed with an interference fit. It Further, in the reduced position (a), the outer peripheral surface of the rod end of the base rod 2 comes into contact with the inner peripheral surface of the moving rod 1 by a stop fit, and the rod tip of the moving rod 1 has a large intermediate diameter of the base rod 2. The taper portion 22A of the portion 22 rides on and is tightened. Therefore, rattling is unlikely to occur between the base rod 2 and the moving rod 1 even in the reduced position.

However, when the moving rod 1 is thickened in order to obtain a large grip force during the pulling-out operation, in the case of the base rod 2 having the same thickness, the gap between the rod outer peripheral surface and the inner peripheral surface of the moving rod is increased. Will become larger. If the wall thickness of the moving rod 1 or the main rod 2 is increased in order to prevent rattling and the gap between them is filled, the weight of the rod increases, and there is naturally a limit to the thickness. For the balance of the rod, you should avoid indiscriminately increasing the weight. From such a background, there has been a demand for a telescopic fishing rod that does not rattle in the state of the reduced position without increasing the thickness of the moving rod 1 or the base rod 2.

[0009]

[Problems to be solved by the device]

 The present invention is intended to solve the problems described above. That is, it is an object of the present invention to provide a telescopic fishing rod that does not rattle at all when set in the contracted position without increasing the wall thickness of the rod.

[0010]

[Means for Solving the Problems]

 Thus, as a result of earnest research to achieve the above object, the present invention was found to solve the conventional drawbacks by utilizing the magnetic force for fixing the moving rod and the original rod, and based on this finding, the present invention was completed. It is a thing.

That is, the present invention is a telescopic fishing rod, which comprises a base rod and a moving rod externally attached to the base rod, and which temporarily fixes the moving rod to the extension rod or the contracted position with respect to the base rod. At the position, the original fishing rod and the movable fishing rod exist in the telescopic fishing rod temporarily fixed by the magnetizing means. Then, the magnetic attachment means attaches the magnetic force between the second ring-shaped magnet body provided at the rod end portion of the base rod and the first magnet body provided on the moving rod so as to face the second ring-shaped magnet body. It exists in the telescopic fishing rod.

[0012] Furthermore, the first magnet body exists in the telescopic fishing rod provided via the rod end cap. The first magnet body also exists in the telescopic fishing rod which is a disc-shaped magnet body provided on the bottom surface of the rod end cap. Further, the bottom of the rod end cap is a stretchable fishing rod having a step portion into which the rod end end of the original rod is fitted.

[0013]

[Action]

 Therefore, since the magnetic force is used in the present invention, even when the moving rod is temporarily fixed in the contracted position, the rod and the moving rod are not thickened without increasing the wall thickness of the rod or the moving rod. Temporary fixing with no rattling can be done.

[0014]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is a device unique to the connecting structure between the base rod and the moving rod in the state of being set in such a reduced position. FIG. 1 shows a first embodiment of a telescopic fishing rod according to the present invention. FIGS. 1 (a) and 1 (b) are views showing a main part of an extension rod according to the first embodiment of the present invention, where (a) shows a contracted state and (b) shows an extended state. Show. The telescopic fishing rod is roughly divided into a base rod 2 and a moving rod 1 movably inserted on the base rod.

The original rod and the movable rod can be obtained by a known manufacturing method, for example, by winding a prepreg sheet of carbon fiber or the like around a core rod and pressurizing and firing in a mold. The movable rod 1 has a thick grip portion 12 at its hand, and is formed into a gentle taper portion 13 from the grip portion 12 to the thin rod portion. The rod tip of the moving rod 1 is gradually reduced in diameter to form a tapered portion 14. The rod butt outer cylinder 11 is fitted and fixed to the rod butt of the moving rod to ensure the strength of the rod butt. A screw is threaded on the inner peripheral surface of the rod-end outer cylinder 11 so that a rod-end cap 3 to be described later can be screwed.

A rod end cap 3 is screwed into the rod end of the moving rod 1 so that it can be removed when necessary. As shown in FIG. 2, the rod end cap 3 includes a screw portion 3A and a grip portion 3B. The grip portion 3B is knurled to prevent slipping so that it can be easily gripped and turned. There is.

The bottom portion 31 of the rod end cap 3 is provided with a first magnet body M1. This magnet body is, for example, a ferrite disk-shaped magnet body, and is attached so as to fit into the inner circumference of the body of the rod end cap 3. However, it is also possible to employ a ring-shaped magnet body instead of the disc-shaped magnet body.

Usually, the telescopic fishing rod is designed so that the rod end cap 3 of the moving rod 1 can be removed and a plurality of tip rods can be taken out and disassembled. It is also possible to blindly seal the tail end of the rod without using the cap 3. Therefore, the magnet body may be provided directly on the rod end of the blindly-moved rod 1 without the rod end cap 3.

On the other hand, the base rod 2 includes a rod bottom large diameter portion 21 and an intermediate large diameter portion 22 which are to be temporarily fixed to the moving rod 1. Here, each large-diameter portion is formed by winding a plurality of layers of prepreg, which is preferably carbon fiber fixed with an epoxy resin, around the movable rod 1.

When the movable rod 1 is in the extended position with respect to the base rod 2, the large rod tail diameter portion 21 is a portion that is temporarily fixed to the inner peripheral surface of the rod tip of the movable rod 1 by an interference fit. Therefore, the large rod-end diameter portion 21 of the base rod 2 has a taper corresponding to the taper portion 14 of the rod tip inner peripheral surface of the moving rod 1, and the moving rod 1 is pulled out from the base rod 2 and extended. When it reaches the position, both taper parts join and stop. Further, the large intermediate diameter portion 22 is a portion that is temporarily fixed with an interference fit with the rod tip of the moving rod 1 when the moving rod 1 is in the contracted position with respect to the original rod 2.

Therefore, the large intermediate diameter portion 22 forms the tapered portion 22A whose diameter gradually increases toward the front. When the moving rod 1 is inserted into the original rod 2 and is just in the contracted position, the rod tip of the moving rod 1 rides on the taper portion 22A and is fixed by an interference fit. By the way, a second magnet body M2 is provided at the end of the rod end of the base rod 2. This magnet body is, for example, a ferrite ring-shaped magnet body, and is attached so as to fit into the inner groove of the rod end of the base rod 2. However, it is also possible to directly fix the rod end face without providing the inner groove.

Since the telescopic fishing rod of the present invention is configured as described above, by inserting the moving rod 1 into the original rod 2, the extension rod (b) is set to the contracted position (a). In this case, the ring-shaped magnet body that is the second magnet body M2 provided on the rod tail portion of the base rod 2 is the magnet body provided on the moving rod 1, for example, the first magnet body provided on the rod tail cap 3. The magnet body M1 and the magnet body M1 are temporarily fixed to each other by a magnetic force.

In this case, even if there is a constant gap L between the outer periphery of the rod end portion of the base rod 2 and the inner periphery of the rod end portion of the moving rod 1, since it is fixed by magnetic attachment rather than interference fit, The original rod 2 and the moving rod 1 will be fixed. Therefore, even if the grip portion 12 is thickened, it is possible to prevent backlash without changing the wall thickness of the base rod 2 or the moving rod 1, which is extremely convenient. Further, the fixing force between the base rod 2 and the moving rod 1 can be adjusted by changing the strength of each magnet body.

Specifically, the fixing force can be easily increased by simply removing the rod end cap 3 provided with the weak magnet body and replacing it with the rod end cap 3 provided with the strong magnet body. You can Furthermore, since the magnet force is not a tight fit, durability is guaranteed without being consumed.

FIG. 3 shows a telescopic fishing rod according to a second embodiment of the present invention. In this case, the rod end cap 3 is provided with a second bottom portion 31B that is one step lower than the bottom (first bottom portion 31A), and the disc-shaped first magnet body M1 is fitted into this bottom portion. (See FIG. 4).

Then, the ring-shaped magnet body, which is the second magnet body M2 provided at the rod tail portion of the base rod 2, is interlocked with the disc-shaped first magnet body M1 provided at the second bottom portion. Magnetically stick to. At this time, the rod end portion of the base rod 2 is fitted into the step portion between the first bottom portion and the second bottom portion, so that the vertical movement in the figure is restricted. Therefore, in the expanded / contracted state, the base rod 2 and the movable rod 1 exert a fixing force in both the up-down direction and the left-right direction shown in the figure, and more reliable temporary fixing is performed.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. For example, the fitting shape of the first magnet body and the second magnet body may be any shape that is free and can be fitted.

[0028]

[Effect of device]

 Since the present invention has the configuration described above, the present invention has various merits such as the following. 1. The grip portion can be thickened without changing the wall thickness of the moving rod or the main rod. 2. By changing the magnets, it is possible to easily change the coupling force between the moving rod and the main rod. 3. In particular, when the first ring-shaped magnet body is fitted in the groove of the moving rod, it can be more securely fixed. 4. Since it does not utilize the frictional force of the eye-to-eye, the temporary fixing force does not decrease and it is highly durable.
