[Detailed Description of the Invention] Industrial Application Field This invention relates to a display device that is placed on a shelf or in a show case in a show room, for example, and used as a room accessory.

BACKGROUND ART Conventionally, as shown in FIG. 7, for example, some toys include a spherical floating body 1 such as a ping pong ball placed in a bowl 2, and a tube 3 having one end connected to the bottom of the bowl 2. It is widely known to play by holding the end of the bowl in your mouth and blowing into the bowl 2 through the tube 3 to blow the floating body 1 up as shown.

However, among the display devices, there was no such display device that could blow up floating bodies to stimulate the sense of hobby.

Problems that the invention aims to solve Therefore, the purpose of this invention is to create a state similar to a state of weightlessness by floating a floating object in the air, and to obtain a display device that arouses interest and stimulates a sense of hobby.

Means for Solving the Problems Therefore, the display device according to this invention includes a blower device 10 that blows air obliquely at a predetermined wind speed, as shown in the illustrated embodiment below, for example.
A floating body 16 receives the wind from the blower 10 and stays in the air, and when the floating body 16 falls, it is caught and guided to a position where it can be blown up again by the blower 10. , and a floating body guide 11b provided integrally with or separately from the air blower 10.

Function: Then, the blower device 10 is operated to blow out wind from the blower device 10, and the floating body 16 is placed at a position where the wind hits, and the floating body 16 is suspended in the air. When the floating body 16 falls due to a disturbance or by turning off the blower 10, the floating body guide 11b catches it and guides the fallen floating body 16 to a position where it can be blown up again by the blower 10. do.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

Figures 1 and 2 show a display device according to this invention, with Figure 1 being a perspective view of its appearance, and Figure 2 being
The figure is a longitudinal cross-sectional view. Reference numeral 10 in the figure is a blower device that blows up wind obliquely at a predetermined wind speed.
The blower device 10 includes a fan 12 in a housing 11.
Store and fix. The fan 12 has a motor 13, and its air outlet 12a faces the air outlet 11a of the housing 11. Then, the motor 13 is driven, and the wind is blown up obliquely at an angle of θ with respect to the horizontal plane as shown in the figure. On the other hand, a lead wire 14 extending from the motor 13 is connected to a switch 15 and then pulled out of the housing 11. The switch 15 is attached to the housing 11 so that it can be operated externally.

On the other hand, reference numeral 16 in the figure indicates the above-mentioned air blower 10.
It is a floating body that stays in the air due to the wind. floating body 16
They are made into a spherical shape from Styrofoam, polystyrene, polypropylene, paper, rubber, etc., and most of them are hollow to make them light, and in some cases they are filled with a gas that has a specific gravity lower than air. good.

The display device according to this invention is constructed as described above. Then, the switch 15 is turned on to blow out the wind from the blower 10, and the floating body 16 is placed at a position where the wind hits. Then, as shown in FIG. 3, the floating body 16 receives a force Fa due to the wind flowing along the spherical surface (an upward force due to the wing principle) and a force Fb directly from the wind. And those forces Fa and forces
When the resultant force Fc with Fb balances the self-force W of the floating body 16,
The floating body 16 floats in the air. As a result, floating body 1
6 will be suspended in the air by the wind from the blower 10. In addition, as a result of experiments, it was found that in order to float the floating body 16, it is preferable to have a wind blowing angle θ of about 40 to 80 degrees.

Now, in the illustrated embodiment described above, the blower device 10
The case in which one fan 12 is provided inside has been described. However, two or more fans may be provided and one floating body 16 may be floated by the plurality of fans. In this way, even if it receives disturbance, the floating body 1
6 can be prevented from falling easily.

By the way, due to the structure of the fan 12, wind is often blown out from the blower device 10 while rotating, for example, in a spiral shape. Therefore, the floating body 16 that receives the wind floats while rotating. It is also interesting that the floating body 16 floats while rotating. However, in some cases, it may be desired to stop the rotation and create a state of floating while remaining stationary.
In such a case, for example, as shown in FIG.
is provided, and the rotation can be adjusted around the connecting shaft 19 between the two by turning an adjustment knob 18 from the outside. Then, the wind direction guide 17 adjusts the flow of the wind blown out from the blower 10,
The rotation of the floating body 16 can be stopped or slowed down. Furthermore, in addition to the configuration shown in FIG. 4, or in addition to such a configuration, it is also effective to eccentrically shift the floating body 16 as shown in FIG. 5 to prevent its rotation. Fifth
In Figure A, a weight 20 is attached to a part of the outer periphery of a solid spherical floating body 16.
B is a hollow floating body 16 with thickened part of the outer circumference 21, C is a solid floating body 16 made by combining a light material 22 and a heavy material 23. It is. In this way, the heavy portion of the floating body 16 is placed downward, and its rotation is prevented.

To add interest to the floating body 16, photographs of planets such as the Earth and the Moon taken by observation satellites such as Landsat may be transferred or illustrations drawn on the surface.
Alternatively, other decorations may be applied. Furthermore, the surface may be roughened in order to increase the force Fa caused by the wind flowing along the surface of the sphere.

Now, in such a display device, the floating body 16 leaves the floating state due to disturbance, and falls when the blower device 10 is turned off. Therefore, in the illustrated embodiment using the above-mentioned spherical floating body 16, as shown in FIGS. 1 and 2, a floating body guide 11b for catching the fallen floating body 16 is provided in the housing 11 and extends from the fan storage portion 11c. shall be established. Then, a groove-shaped guide surface is formed on the floating body guide 11b, and the center is concave and slopes toward the ventilation hole 11a. Roll it in the direction of the ventilation hole 11a shown by the dotted chain line. As a result, when the floating body 16 falls due to a disturbance, it is blown up again by the wind from the blower 10 and automatically returns to the floating state. On the other hand, when the blower device 10 is turned off, the floating body 16 is automatically set, and when the blower device 10 is turned on later, the floating body 16 can be blown up to be in a floating state again.

Therefore, the floating body guide 11b is not limited to a table-shaped one as shown in FIGS. 1 and 2, but can be made by bending a wire rod into a U-shape, for example, as shown in FIG. It may be formed so as to be attached to the portion 11c.

By the way, in the illustrated embodiment described above, the case where the floating body guide 11b is provided integrally with the air blower 10 has been described. However, the floating body guide may not be provided integrally with the blower device 10 but may be provided in a separate pair.

Furthermore, in the illustrated embodiment described above, an example was shown in which this invention was applied to a device that only functioned as a display device. However, for example, a deodorizer or an aromatic agent is placed inside the housing 11 of the above-mentioned embodiment, and it is sequentially vaporized by the fan 12 and sent out from the air blower 10 along with the wind that floats the floating body 16. It can also be applied to devices that have the functions of a deodorizer and an aroma device as well as a deodorizer and an aroma device. Further, by providing a filter or an electrostatic precipitator at the air intake port of the blower device 10, the blower device 10 can also be applied to a device that also functions as an air purifier.
Furthermore, if the floating body is made to float by using air from the humidifier, it is also possible to combine it with a humidifier.

Effects of the invention Therefore, according to this invention, the blower blows up wind diagonally at a predetermined wind speed, and the wind makes the floating object stay in the air. It can create a mood, arouse the viewer's interest, and stimulate a sense of taste, making it useful as a room accessory, for example.

Moreover, when the floating body falls due to disturbance,
The floating body guide catches it and guides it to a predetermined position, and the blower blows it up again to automatically return it to a floating state. In addition, when a floating object falls due to turning off the blower, it can be caught by the floating object guide and guided to a predetermined position, and when the blower is turned on later, the floating object can be immediately blown up into a floating state. can. Then,
According to this invention, the effort of setting up the floating body can be saved by simply turning the blower on and off.
