【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, the display device includes a water tank 11 in which water W containing an antiseptic is stored, a plurality of types of models 12 contained in the water W in the water tank 11, and a water tank 11 inside. And a bubble generator 13 for generating bubbles.

The water tank 11 is composed of a peripheral wall 21 having a hexagonal horizontal cross section and a flat bottom wall 22 which are integrally molded of transparent plastic. The upper end of the peripheral wall 21 is covered with a plastic cover 23. A UV lamp 24 is attached to the lower surface of the cover 23. The lamp 24 enhances the display effect and prevents algae or the like from being generated in the water tank 11. Pebbles, gravel, etc. 25 are laid on the upper surface of the bottom wall 22.

The plurality of types of models 12 have various sizes and shapes, but all are made to resemble the shape of a tropical fish or a goldfish. One of the models shown in FIGS. 2 and 3 will be described. This is a substantially flat elliptical floating body 31 that occupies most of the entire model 12, and is fixedly embedded in a part of the outer periphery of the floating body 31. It consists of a weight 32. The floating body 31 is made of an independent rubber foaming resin having a specific gravity of about 0.6 and has water resistance. The outer surface of the floating body 31 is colored. Further, the outer surface of the floating body 31 may be subjected to a treatment for improving wettability so that air bubbles do not easily adhere to the outer surface of the model 12. If air bubbles are attached to the outer surface of the model 12, the buoyancy of the model 12 changes, which is not preferable. The weight 32 is made of lead. Referring to FIG. 3, the center of gravity G of the floating body 31 is in the middle of the height, but there is a weight 32 at a distance L below the center of gravity G. This position corresponds to the center of the lower edge of the abdomen of the tropical fish represented by the model 12. The specific gravity of the entire model 12 is adjusted to 1 ± 0.002. When the specific gravity is 1.002, the sinking speed is about 2.5 cm / sec, and when the specific gravity is 0.998, the floating speed is about 2.5 cm / sec.

The bubble generator 13 includes a substantially ring-shaped one-end closed porous tube outlet member 41 received by the bottom wall 22 of the water tank 11, and a cover 23 penetrating from the outside of the water tank 11 into the water tank 11. It comprises a supply pipe 42 which is inserted and has one end connected to the other end of the outlet member 41, and a generator main body 43 connected to the other end of the supply pipe 42. In the case of the generator main body 43, a motor, a compressor and the like not shown are housed.

When pressurized air is sent from the generator body 43 to the outlet member 41 through the supply pipe 42, fine bubbles are blown out from around the outlet member 41. When the bubble blown out rises, an upflow is generated with it, and as a reaction to this, a downflow occurs. Leftward and rightward flows are generated by the upward and downward flows, and as a result, a complicated water flow is generated in the water tank 11. On the other hand, the stagnant part of the water flow also occurs, and the stagnant place itself moves.

The plurality of models 12 put in the water W move vertically and horizontally as if the raw fish were swimming around. When Model 12 came to a stagnant stream of water, it stood there, which looked as if raw fish were poking. When the stagnation disappears due to the movement of the water flow, the stationary model 12 moves again. These look like raw fish swimming around, especially when viewed from a distance.

As shown in FIG. 4, when the supply of the pressurized air is stopped, the water flow in the water tank 11 disappears. Then, due to the slight difference in specific gravity between the model 12 and the water W, the heavy model 12 sinks to the bottom of the water, and the light model 12 floats up to near the water surface.

FIG. 5 and FIG. 6 show modified examples of the model. The model 50 according to this modification has a floating body 51. The floating body 51 is made to resemble a goldfish, and includes a fish body portion 52 that hits the fish body, a belly fin portion 53 that hits the belly fin, and a tail fin portion 54 that hits the tail fin. The fish body portion 52 is made of the same resin as the floating body 31 of the model 12. A weight 55 is embedded in the belly of the fish body portion 52. Further, a back fin portion 56 and a tail protrusion portion 57 are integrally formed with the fish body portion 52. The belly fin portion 53 and the tail fin portion 54 are both made of HPPE film. The thickness of the film is 0.01 to 0.02 mm. The belly fin portion 53 is formed in a substantially triangular shape, and is bonded to a portion corresponding to the belly of the fish body portion 52 at one vertex of the triangle. The tail fin portion 54 is formed into a predetermined shape, then bent so as to have an inverted V-shaped cross section, and adhered to the tail protrusion portion 57 at one end of the bent portion.

As described above, when the portions protruding from the fish body portion 52 such as the belly fin portion 53 and the tail fin portion 54 are flexible films, this is a solid material in the aquarium 11, such as pebbles and gravel. There is no worry about getting caught in 25 etc.

7 to 9 show another modified example of the model. The model 61 according to this modification has a floating body 60. The floating body 60 is composed of a fish body portion 62 corresponding to a fish body, a lower jaw portion 63 corresponding to a lower jaw, and a tail fin portion 64 corresponding to a tail fin. The fish body portion 62 has a specific gravity of 0.8-0. It is molded from about 9 synthetic resins, and a back fin 62a, a chest fin 62b, and a belly fin 62c are integrally formed therewith. A weight 67 is embedded in the belly of the fish body portion 62. Both the lower jaw 63 and the tail fin 64 are made of synthetic resin having a specific gravity of about 1.0. As shown in FIG. 8, the fish body portion 62 and the lower jaw portion 63 are connected by a horizontal pin 68, and the lower jaw portion 63 is vertically swingable with respect to the fish body portion 62. As shown in FIG. 9, the fish body portion 62 and the tail fin portion 64 are connected by a vertical pin 69, and the tail fin portion 64 is horizontally swingable with respect to the fish body portion 62.
