Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a stone that is placed in an aquarium for breeding various fish such as tropical fish, goldfish, and edible fish (hereinafter referred to as tropical fish), and beautifully decorates the inside of the aquarium.
The present invention relates to rocks, driftwood, and various other forms of ornaments.

[0002]

2. Description of the Related Art Rearing of tropical fish has been actively carried out all over the world. Especially in Europe, it has been popular as an interior article for office and home sitting room since ancient times, and in Japan, it has been rapidly increasing in popularity in recent years.

Generally, the bottom of an aquarium for cultivating tropical fish and the like is laid with sand, ornaments such as stones, rocks and driftwood are arranged, and aquatic plants are planted to produce beauty. Most of the above-mentioned ornaments are natural objects, and for example, stones such as gold ore and five-color stone are often used.

[0004] In addition, lighting equipment such as fluorescent lamps and mercury lamps, which are indispensable for the growth and reproduction of tropical fish, aquatic plants and filtered bacteria, are provided in the aquarium.
It also plays an important role in illuminating the ornaments and water plants to bring out their beauty.

[0005]

The conventional decorative body made of a natural object merely reflects the light from the luminaire and exhibits the original color and pattern of the natural object. The effect was low. Also,
When the lighting fixtures were turned off, the inside of the aquarium became difficult to see, and it was usually difficult to watch.

Therefore, an object of the present invention is to enhance the display effect in the aquarium by making the ornament itself shine beautifully, or even if the lighting equipment is turned off, the ornament itself shines light for a while. Therefore, it is to provide a decorative body that allows the user to continue watching the aquarium.

[0007]

In order to achieve the above object, the ornamental body of the fish tank of the present invention is mixed with the synthetic resin forming the main body and the synthetic resin non-uniformly so as to form a pattern. And a fluorescent dye that has been prepared.

Further, another decorative body of the present invention comprises a synthetic resin forming a main body and a luminescent pigment which is non-uniformly mixed with the synthetic resin so as to form a pattern.

Here, the synthetic resin is not limited to a specific one, and examples thereof include polyester resin, epoxy resin, and phenol resin. Also, the color of the fluorescent dye is arbitrary,
Red, peach, orange, yellow, green, blue, purple, and other various colors can be used alone or in combination. In addition, in order to form a ground color, it is preferable to mix a dye different from the fluorescent dye or the night-light dye with the synthetic resin.

[0010]

[Function] The decorative body containing the fluorescent dye not only receives the light from the lighting fixture and reflects it, but also emits fluorescence and shines beautifully, so that it can be recognized from a long distance, and the display effect in the aquarium can be obtained. Will increase. Moreover, since the fluorescent dyes are mixed nonuniformly so as to form a pattern, the appearance and texture of natural objects can be obtained.

Since the decorative body containing the luminous pigment shines light upon receiving the light from the lighting equipment, it can produce a unique beauty. Further, even if the lighting equipment is turned off, the ornament itself emits the night light and shines thinly for a while, so that the user can continue watching the aquarium. Moreover, since the luminous pigments are mixed nonuniformly so as to form a pattern, the appearance and texture of natural objects can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the present invention is embodied in an artificial stone laid on the bottom of an aquarium will be described below with reference to the drawings.
As shown in FIG. 2, the artificial stone 1 comprises a polyester resin 2 forming a main body, a fluorescent dye 3 and a calcium powder mixed non-uniformly in the polyester resin 2 so as to exist as a marble pattern only on the surface portion. 4 and. The calcium powder 4 is for making the ground color of the artificial stone 1 white. The raw material ratio is as follows.

Liquid polyester resin 82-95% Curing catalyst 0.01% Fluorescent dye 4-10% Calcium powder 1-8%

This artificial stone 1 has the following procedure (not shown)
Manufactured in. (1) Add the curing catalyst to the liquid polyester resin and stir it sufficiently to mix it uniformly.

(2) A part of this polyester resin is divided into small portions, a fluorescent dye and calcium powder are added thereto, and the mixture is stirred appropriately. Since the polyester resin has a high viscosity, it is not uniformly mixed even if it is slightly stirred, and the degree of mixing is approximately proportional to the number of times of stirring. Therefore, if the stirring is adjusted, a marble pattern like natural stone can be formed.

(3) The mixture of (1) and (2) above is poured into a flexible rubber mold (not shown). The mixture of the above (2) is injected into the part of the rubber mold which is attached to the surface of the mold, and the mixture of the above (1) is injected into the inside. This allows
The fluorescent dye and calcium powder are present only on the surface of the artificial stone. The polyester resin is rapidly cured by the action of the curing catalyst while generating heat, and becomes the artificial stone 1 having the marble pattern. This artificial stone 1 can be easily released from the rubber mold.

(4) Excessive polyester resin is scraped off from the released artificial stone 1 to adjust the outer shape. Finally, artificial stone 1
The surface is finished with matte sandpaper.

The artificial stone 1 of this embodiment is used by being laid on the bottom of a water tank 10 as shown in FIG. Since this artificial stone 1 contains the fluorescent dye 3, it receives light from the lighting fixture 11,
It not only reflects it, but fluoresces itself and shines beautifully. Therefore, it can be recognized from a distance, and the display effect is enhanced. Therefore, the water tank 10 laid with the artificial stone 1 is particularly suitable as an interior article for offices, hotel lounges, restaurants, coffee shops, and the like.

Further, since the fluorescent dye 3 and the calcium powder 4 form a marble pattern and the surface of the artificial stone 1 is matte, the appearance and texture of natural stone can be obtained. Furthermore, the fluorescent dye 3 and the calcium powder 4 are artificial stones 1.
Since it is present only on the surface portion of (1) (However, it is also present on the core portion to some extent due to manufacturing error.), The addition amount can be reduced compared with the case where it is present on the whole.

Next, FIG. 1 also shows the artificial rock 5 of the second embodiment. This artificial rock 5 is manufactured and constructed in the same manner as the artificial stone 1 of the first embodiment except that a luminous pigment is added instead of the fluorescent pigment.

Since the artificial rock 5 contains the luminescent pigment, it receives light from the luminaire 11 and shines thinly to produce a unique beauty. In addition, since the luminous pigment forms a pattern, a natural rock-like appearance and texture can be obtained. Also, the lighting equipment 11
Even if is turned off, for example, the artificial rock 5 itself emits night light and shines thinly for 3 to 4 hours, so that it is possible to continue watching the water in the aquarium 10. In addition, the aquarium 10 in which the artificial rock 5 is placed is installed in, for example, a karaoke room, the lights in the room and the aquarium are turned off, and the artificial rock 5 shines thinly when the video screen disappears. Law is also possible.

FIG. 1 also shows an artificial driftwood 6 of the third embodiment. The artificial driftwood 6 is manufactured and constructed in the same manner as the artificial stone 1 of the first embodiment except that the fluorescent dye and the luminescent pigment are added together. This artificial driftwood 6
