And contained in a cylindrical resin container in a state of being isolated from the other liquid. In this luminous body, a chemiluminescence phenomenon is caused by elastically bending a container at the time of its use to break a capsule therein, and reacting the fluorescent liquid and the oxidizing liquid.

[0003]

SUMMARY OF THE INVENTION
Since the light cannot be emitted again after the duration of the chemiluminescence phenomenon has elapsed, those having passed the duration are discarded. However, there is a problem that the environment is deteriorated because the cases that are discarded in the sea or the sandy beach do not follow. In addition, harmful chemiluminescent liquid may leak from the discarded container, resulting in marine pollution. The present invention has been made in view of the above problems, and has as its object to provide a luminous fishing device that can be repeatedly used over a long period of time and has little adverse effect on the environment.

[0004]

According to the present invention, there is provided a light-storing fishing device according to the present invention, wherein a light-storing phosphor which emits light for a certain time every time light is irradiated is accommodated in a transparent sealed container. It is characterized by the following (claim 1). According to this light-storing fishing device, light can be emitted for a certain period of time by irradiating light to the light-storing phosphor whose luminance has decreased or has stopped emitting light.

The phosphorescent phosphor is CaAl ₂ O ₄ , S
It is preferable that at least one metal element selected from rAl ₂ O ₄ and BaAl ₂ O ₄ is used as a mother crystal (claim 2). In this case, light can be stably emitted with high luminance for a long time.

[0006] The sealed container may be formed of a cylindrical body having a C-shaped cross section that can be fitted to a pole tip.
In this case, the movement of the pole can be easily visually recognized by attaching the pole to the pole in night fishing. Further, the sealed container may be made of a rod-shaped body (claim 4). In this case, in night fishing, it is possible to exert a fish collecting effect by attaching it to, for example, a harris near a hook. The movement of the float can be easily visually recognized by attaching it to the float or a fishing line near the float.

[0007]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a luminous fishing gear according to one embodiment of the present invention. This luminous fishing gear A has a luminous phosphor 2 housed inside a transparent sealed container 1 and is used by being attached to the tip of a fishing rod B. The sealed container 1 is made of synthetic resin having high transparency such as acrylic resin.
It is formed into a cylindrical body having a C-shaped cross section, and a closed space 3 for accommodating the phosphorescent phosphor 2 is formed between the inner periphery and the outer periphery (see FIG. 2). The width D of the slit 4 provided on the peripheral surface of the sealed container 1 is slightly smaller than the outer diameter E of the tip of the fishing rod B to be applied, and the inner diameter is the outer diameter E of the tip of the fishing rod B. And almost match. Therefore, by forcibly fitting the sealed container 1 to the rod tip through the slit 4, the sealed container 1 can be easily fitted and attached to the rod tip.

The phosphorescent phosphor 2 emits light for a certain period of time when stimulated by irradiation of light including ultraviolet rays, and is composed of CaAl ₂ O ₄ , SrAl ₂ O ₄ and BaAl ₂ O.
A material in which at least one metal element selected from No. ₄ is used as a mother crystal, or a material in which a compound obtained by adding magnesium to these metal elements is used as a mother crystal is used. These phosphorescent phosphors 2 include, for example, the above-mentioned CaAl ₂ O ₄ , SrAl ₂
One or more metal elements selected from O ₄ and BaAl ₂ O ₄ and alumina and europium oxide (Eu ₂ O ₃ )
And a flux such as boric acid and the like, and then mixing them, followed by firing in a nitrogen-hydrogen mixed gas stream. The phosphorescent phosphor 2 thus obtained is contained in the sealed container 1 in the form of any one of a small block, a powder, and a granule, or a mixture of these forms.

The light-storing fishing gear A having the above-described structure irradiates the light-storing phosphor 2 with light containing ultraviolet rays emitted from a strobe or a fluorescent lamp through the sealed container 1 so as to emit the light.
By stimulating, self-emission can be performed for a certain period of time. In particular, in this embodiment, the phosphorescent phosphor 2 includes CaAl ₂ O ₄ , SrAl ₂ O ₄ and BaA.
Since one or more kinds of metal elements selected from l ₂ O ₄ are used as a mother crystal, or a compound obtained by adding magnesium to these metal elements is used as a mother crystal, high brightness and stable for a long time It can be made to emit light. For this reason, by attaching to the pole tip at night fishing, the movement can be easily visually recognized, and thereby the fish can be easily and reliably recognized.

Further, the phosphorescent phosphor 2 can emit light repeatedly for a certain period of time every time light is irradiated, so that it can be used many times over a long period of time. Therefore, the adverse effect on the environment is extremely small as compared with the conventional disposable type. In addition, it is conceivable that the phosphorescent phosphor is pulverized into a fine powder, which is added to the paint and applied as a luminescent paint to a pole tip or kneaded into the sealed container 1 itself. In this case, This is not preferable because the luminance is lower than that of the above embodiment in which the phosphorescent phosphor 2 is housed in the sealed container 1 as it is.

The sealed container 1 may be made of a rod-shaped body (see FIG. 3). In this case, in night fishing, for example, as shown in FIG. By attaching using such as, it is possible to exert the effect of collecting fish. Further, as shown in FIG. 5, the movement of the float 7 can be easily visually recognized by attaching it to the float 8 or the fishing line 9 in the vicinity thereof, so that the fish can be easily and reliably recognized. .

The luminous fishing device A of the present invention is not limited to the above-described embodiment. For example, the luminous fishing device may be configured as a float by imparting buoyancy to the sealed container 1.
Various design changes can be made, such as storing the metal in the sealed container 1 and configuring the luminous fishing device as a weight.

[0013]

As described above, according to the light-storing fishing device of the first aspect, the light-storing phosphor can be repeatedly used to emit light by irradiating light to the light-storing phosphor. The adverse effect on the environment is extremely small compared to the disposable type.

According to the luminous fishing device of the present invention, the luminous phosphor contains at least one metal element selected from CaAl ₂ O ₄ , SrAl ₂ O ₄ and BaAl ₂ O ₄ in the mother crystal. Therefore, light can be stably emitted with high luminance over a long period of time. For this reason, a fish collecting effect and a visual recognition effect can be favorably exhibited over a long period of time.

According to the luminous fishing device according to the third aspect, the movement can be easily visually recognized by being attached to the rod tip in night fishing. For this reason, it is possible to easily and reliably recognize the area near the fish. According to the luminous fishing device of the fourth aspect, in night fishing, for example, by attaching it to the harris near the fishhook, the fish collecting effect can be exhibited well. In addition, by attaching the float to the fishing line or the fishing line in the vicinity thereof, the movement of the float can be easily visually recognized, and the vicinity of the fish can be easily and reliably recognized.
