Modes for Carrying Out the Invention
[0008] Hereinafter, an embodiment of the fishing device proposed here will be described with reference to the drawings. Note that the present invention is not limited to the following embodiments. The drawings are schematically drawn and do not necessarily reflect the actual objects. Also, parts having the same function are appropriately given the same reference numerals, and duplicate explanations are omitted.
[0009] Here, as an example, a fishing device for smelt fishing will be described, but the present invention is not intended to be limited to what is described in such an embodiment. The fishing device proposed here is not limited to a fishing device for smelt fishing and is applicable to fishing devices for various uses. For this reason, the thickness, length, etc. of the main line and floats can be variously changed.
[0010] Figure 1 is a schematic diagram of the fishing device 10 proposed herein. The fishing device 10 is attached to a fishing rod via a fishing line 20. In this embodiment, a Harris stopper 22 is attached to the upper end of the main line 12 of the fishing device 10. The fishing line 20 is attached to the Harris stopper 22 attached to the upper end of the main line 12. A weight for dropping the fishing device 10 into the water is attached to the lower end of the main line 12 of the fishing device 10. In this embodiment, a snap 24 is attached to the lower end of the main line 12 of the fishing device 10. A weight is attached to the fishing device 10 via the snap 24. A bottom hook may be attached to the weight. Note that the components attached to the upper and lower ends of the main line 12 are not particularly limited. As the components attached to the upper and lower ends of the main line 12, in addition to the Harris stopper and the snap, for example, a swivel or the like can be used.
[0011] The fishing device 10 proposed herein includes a main line 12 and a plurality of Harrises 16. The main line 12 has a large-diameter portion thicker than the average diameter of the main line 12 and a small-diameter portion thinner than the average diameter of the main line 12. In this embodiment, the main line 12 is composed of a plurality of threads 12a, 12b having different thicknesses. The thread 12a constitutes the large-diameter portion of the main line 12. The thread 12b constitutes the small-diameter portion of the main line 12. The threads 12a, 12b are connected at a connecting portion 14. As the threads 12a and 12b, for example, threads made of nylon, PE, polyester, fluorocarbon, or the like can be used. In this embodiment, nylon threads are used as the threads 12a, 12b. Thus, by using threads 12a, 12b having different thicknesses, the configuration of the main line 12 can be easily changed.
[0012] In the above-described embodiment, the main line 12 was composed of the lines 12a and 12b, but it is not limited to such a form. The main line 12 may be composed of, for example, three or more lines having different thicknesses. Also, the thickness configuration etc. of the main line 12 can be appropriately set according to the movement of the bait that is likely to attract the target fish. For example, the lower part of the main line 12 may be thicker than the upper part.
[0013] In this embodiment, the large-diameter part is provided at the upper part of the main line 12, and the small-diameter part is provided at the lower part of the main line 12. That is, the line 12a is provided at the upper part of the main line 12. The line 12b is provided at the lower part of the main line 12. Hereinafter, the line 12a will be appropriately referred to as the upper line 12a, and the line 12b will be referred to as the lower line 12b. The lower line 12b below the connecting part 14 is thinner than the upper line 12a above the connecting part 14 of the main line 12. The thicknesses of the upper line 12a and the lower line 12b are not particularly limited, but in smelt fishing, as the upper line 12a, a line of size 0.2 to 0.4 is often used, and for example, a line of size 0.25 to 0.3 can be used. As the lower line 12b, a line of size 0.125 to 0.25 is often used, and for example, a line of size 0.175 to 0.2 can be used. The thickness of the lower line 12b relative to the upper line 12a is not particularly limited, but it may be about 0.6 to 0.95, and for example, it may be about 0.7 to 0.9. In this embodiment, a line of size 0.3 is used as the upper line 12a. As the lower line 12b, a line of size 0.2 is used. The type and thickness of the line used for the main line 12 are not limited to those described above, and various changes are possible.
[0014] The threads 12a and 12b are connected below the middle of the range where the plurality of harries 16 are attached to the main thread 12. The configuration of the connecting portion 14 is not particularly limited, and a plurality of upper threads 12a and lower threads 12b having different thicknesses may be connected in various ways. From the viewpoint of allowing natural movement when the fishing rig 10 is moved up and down, the connecting portion 14 is preferably light. Also, from the viewpoint of preventing the fishing hook 18 from getting caught in the connecting portion 14, the connecting portion 14 preferably has a simple configuration. For example, at the connecting portion 14, it is preferable to connect the upper thread 12a and the lower thread 12b by tying them together. The method of tying the upper thread 12a and the lower thread 12b at the connecting portion 14 is not particularly limited, and examples include a reef knot, a surgeon's knot, a blood knot, etc. Here, a reef knot can be preferably adopted as it is easy to tie the threads 12a and 12b having different thicknesses together and the knot tends to be thin. In this embodiment, at the connecting portion 14, the upper thread 12a and the lower thread 12b are connected by a reef knot.
[0015] A plurality of harries 16 are attached to the main thread 12 at intervals. The harry 16 is a thread to which a fishing hook 18 is attached at its tip. The fishing hook 18 is attached to the harry 16 via the thimble 17. As the harry 16, for example, the same type of thread as the thread used for the main thread 12 can be used. In this embodiment, a nylon thread is used as the harry 16. The number of harries 16 is not particularly limited, and for example, in smelt fishing, it can be about 5 to 15. In this embodiment, 6 harries 16 are attached to the main thread 12. 3 harries 16a are attached to the upper thread 12a. The length of the harry 16a is about 3.5 cm. 3 harries 16b are attached to the lower thread 12b. The length of the harry 16b is about 3 cm. The harry 16a attached to the upper thread 12a is a 0.2 - sized thread. The harry 16b attached to the lower thread 12b is a 0.175 - sized thread. That is, the harry 16b attached to the lower thread 12b is thinner than the harry 16a attached to the upper thread 12a. The thickness of the harry 16 may be appropriately changed according to the target fish, the fishing hook used, etc.
[0016] In this embodiment, the total length of the main line 12 is approximately 80 cm. Among the weights 16a attached to the upper line 12a, the lowermost weight 16a is attached approximately 6 cm above the connecting portion 14. The interval between the weights 16a attached to the upper line 12a is approximately 14 cm. Among the weights 16b attached to the lower line 12b, the uppermost weight 16b is attached approximately 6 cm below the connecting portion 14. The interval between the weights 16b attached to the lower line 12b is approximately 11 cm. In this embodiment, the interval between the weights 16b attached to the lower line 12b is narrower than the interval between the weights 16a attached to the upper line 12a.
[0017] As described above, the main line 12 of the fishing device 10 proposed here has a large-diameter portion (here, the line 12a) that is thicker than the average diameter of the main line 12 and a small-diameter portion (here, the line 12b) that is thinner than the average diameter of the main line 12. According to such a fishing device, it is easy to cause a change in the movement of the bait attached to the fishing hook. Thereby, an improvement in the fishing result is expected.
[0018] In this embodiment, the large-diameter portion is provided at the upper part of the main line 12, and the small-diameter portion is provided at the lower part of the main line 12. Therefore, the center of gravity of the main line 12 is closer to the upper end side. With such a configuration, when the fishing device 10 is dropped into the water and moved up and down to attract ayu, it is difficult for the main line 12 to bend. As a result, it is difficult for a difference to occur in the movement of the attached fishing bait between the upper and lower parts of the main line 12, and it is easy to attract ayu. Further, since the upper line 12a is thick, for example, the upper part of the main line 12, which bears a large load when a plurality of ayu are caught, is not easily cut.
[0019] Further, the main line 12 is connected below the middle of the range where a plurality of weights 16 are attached. Thereby, the center of gravity position of the entire main line 12 is adjusted, and the operability when moving the fishing device 10 up and down is improved.
[0020] The harisu 16b attached to the lower line 12b is thinner than the harisu 16a attached to the upper line 12a. Also, the interval between the harisu 16b attached to the lower line 12b is narrower than the interval between the harisu 16a attached to the upper line 12a. As a result, when moving the fishing rod up and down, it becomes easier to link the harisu 16a and 16b with the movement of the upper line 12a and the lower line 12b.
[0021] Figure 2 is a schematic diagram of the fishing device 10a proposed here. In the embodiment shown in Figure 2, as the main line, a so-called tapered main line 13 in which the line gradually becomes thinner from the upper end to the lower end is used. The main line 13 does not have a connecting portion 14 (see Figure 1) and is composed of a single line. In this embodiment, in the main line 13, the upper part thicker than the average diameter of the main line 13 constitutes a large-diameter part, and the lower part thinner than the average diameter of the main line 13 constitutes a small-diameter part. Even with such a fishing device 10a, as described above, like the fishing device 10, it is possible to cause a change in the movement of the bait.
[0022] As described above, the embodiments of the fishing device proposed here have been explained, but these are merely examples and do not limit the scope of the claims. The invention disclosed here includes various modifications and changes of the above specific examples. Each component of the fishing device may not be provided unless otherwise specifically mentioned. Also, additional elements may be provided.
