DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to air in the floating body apparatus, and in particular fed through the interior of the hollow supports for the air in the float body in the air float suspended by the wind as the like carp and streamers compression Even though it is indoors without wind and blowing air, it floats as if swimming under the wind of nature, and the strange phenomenon that the carp streamer swims even if there is no wind for the person who saw this I feel let it is possible to enhance the publicity effect, yet noise it was so requires less consumption of small compressed air, of the preferred sky in the floating body apparatus to display at exhibitions.

[0002]

2. Description of the Related Art Toys and advertisements are known as air-floating devices in which a bag-shaped air-floating device is filled with a gas lighter than air, such as helium gas, so that the air floats by the buoyancy. It has been put to practical use as an advertising display.

[0003] However, the above-mentioned floating body can be used only for an air floating body formed in a bag shape. For example, a floating air body of a tubular cloth through which air passes like a carp streamer is floated. I couldn't do that.

[0004] Floating a floating body of a tubular cloth such as a carp streamer may be necessary as a display for advertising or as a scene in a play, but it is usually impossible to swim a carp streamer in a room without wind. I couldn't do it, just fixed my swimming figure and substituted it.

[0005] However, if the fixed state is far from the state of swimming, it is not interesting, and it lacks the truth, and if it is necessary to swim the streamer in order to have more truth, a large fan is rotated. There was no other choice but to raise the wind around the carp indoors in a very wide area and to swim. The consumption of compressed air was extremely high and there was a drawback that a large-scale device was required.

[0006] In addition, a large fan requires a large amount of power to rotate, and is inconvenient to be used as an advertising display which requires continuous blowing for a long period of time.

When a large fan is rotated in the room to blow the wind, it is necessary to consider the influence on the surroundings, such as lighting lamps, various curtains, props, and children's tools. It was difficult to blow the necessary wind.

In an automobile exhibition or the like, the vehicles participating in the rally are displayed in order to have a more realistic feeling when exhibiting the participating vehicles by expressing the pattern of the rally with the carp streamer flying over the roof of the cab. At the exhibition venue, attach a carp streamer on the roof of the cab, and in the exhibition hall, swim the carp streamer while running pictures and images of the background desert and dunes behind the vehicle, making it appear that the participating vehicles are running in the desert. May be planned. However, as a means of swimming a carp streamer on a stopped vehicle, a large fan is rotated in front of the vehicle so that the carp streamer attached to the vehicle can swim for a long period of time, for example, two weeks. It is difficult to realize because of the large impact on the audience, companions, clerks, other booths, etc. due to being noticeable, noise and strong wind.

Therefore, in order to make the streamer look like it is swimming in a simulated manner, a wing like an airplane is provided on the back of the streamer, or the back of the streamer is sent in the form of a wing, and the wind is sent to the wings. An attempt was made to swim the streamer with the generated lift, but it was found that a very strong wind was required to lift the weight of the streamer with the lift, which was not practical.

Attempts have also been made to provide a rotating spiral spring or a rotating disk inside the carp streamer, but this not only complicates the equipment, but is far from the carp streamer that swims in the wind, and lacks the trueness of the carp streamer. It was nothing.

[0011]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and an object of the present invention is to form an opening by a rigid wire and to increase the body length. To the air-floating body consisting of a tubular cloth with a cored bar arranged to support its own weight along the upper part of the first half of the air-floor through the inside of a hollow support that horizontally supports the air-floating body. By blowing the compressed air from the nozzle toward the opening, it is possible to allow the airborne body to float in the air in a natural state,
It is another object of the present invention to allow airborne bodies to float freely even indoors where there is no wind.

[0012]

It is still another object of the present invention to provide a hollow column fixed to the roof of a cab of a vehicle, wherein a rigid wire is used to hold the mouth open , and that the length is at least half the length in the first half of the length. Attach a carp streamer with a metal core to support its own weight along the back, and blow out compressed air horizontally from the nozzle provided on the side of the hollow support toward the mouth of the carp streamer ,
The purpose is to make the streamer swim as if swimming outdoors even in a windless exhibition hall, and to give visitors a sense of realism and enhance the advertising effect.
