[0019]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a pole for mounting a flag 2. The pole 1 is erected on a base 4 on an upper surface of a box 3 placed on the ground, and air is sucked into the box 3 from outside. A blower 5 for feeding into the pole 1 is housed.

The pole 1 is composed of a lower pole 1a erected on the base 4 and an upper pole 1b connected to the upper end of the lower pole 1a. The lower pole 1a and the upper pole 1b are connected by a connection pipe 12. The upper part of the connection pipe 12 is fixed to the lower end of the upper pole 1b. The lower part of the connection pipe 12 protrudes from the lower end of the upper pole 1b. The upper end of the lower pole 1a is detachably attached to the lower part of the connection pipe 12 with screws or the like. An inner pipe 13 is formed inside the connection pipe 12. Inner tube 1
The upper end of 3 is fixed to the upper inner wall of the connection pipe 12, and the lower end of the inner pipe 13 is provided with a duct hose mounting portion 14. The duct hose mounting portion 14 connects the upper end of the duct hose 10 to the lower end of the inner pipe 13 by a band 14a.

The lower end of the duct hose 10 is connected to the blower 5. The air sucked from the outside of the box 3 by the blower 5 is sent to the inner tube 13 by the duct hose 10, and is sent from the upper end of the inner tube 13 into the upper pole 1b.

The box 3 has a panel 3a removably attached to only one surface thereof, and a suction surface of a blower 5 is formed on the opposite side of the panel 3a.

On panel 3a, blower 5 is turned ON / OF.
An ON / OFF switch 7 for performing F, an adjustment switch 8 for adjusting the air volume, and a suction window 9 for maintaining the pressure in the box 3 at normal pressure are provided.

The box 3 houses a blower 5, an inverter-type driver 6 for driving the blower 5, and a duct hose 10. The driver 6 can also be controlled by a remote controller 20 or a remote switch 21 as shown in FIG. 5 or FIG.

The blower 5 is an air supply source having a very simple structure as compared with an air supply source such as a high-pressure compressor. The air sucked from the outside of the box 3 by the blower 5 is directly supplied to the upper pole 1b from the opening at the upper end of the inner pipe 13 through the duct hose 10 without being compressed.

At the position where the flag 2 of the upper pole 1b is attached, a pair of air jet nozzles 15, 16 and the like 3
A pair of air jet nozzles is provided. As shown in FIG. 3, the pair of air ejection nozzles 15 and 16 have holes symmetrically positioned so as to surround the mounting end of the flag 2. The hole directions of the air jet nozzles 15 and 16 at the uppermost stage extend in a direction each forming an angle of about 3 degrees with respect to the symmetric position, and thus in a direction forming an angle of about 6 degrees with each other. In addition, the air ejection nozzles 15a, 1
6a, 15b and 16b each extend in a direction at an angle of about 5 degrees with respect to the symmetrical position, so that they are approximately 10 degrees apart from each other.
Spread in the direction of the angle of the degree.

The air jet nozzles 15 and 16 are approximately 3
The air ejection nozzles 15a, 16a, 15b, and 16b are oriented upward so as to have a steep angle of about 10 degrees.

The air jet nozzles 15 and 16 have a diameter of 7 mm.
Air outlet nozzles 15a, 16a,
15b and 16b have openings with a diameter of 12 mm.

As described above, the pair of air ejection nozzles 1
When the divergence angle of 5, 16 or the like is smaller than 3 degrees, the flag 2 flutters too flatly, giving a different feeling from the case where the flag 2 flutters naturally due to the natural wind.
If it is greater than 0 degrees, the jetting air cannot easily escape the flag 2 effectively.

The suppression angle of the air jet nozzle 15 and the like is 3
It may be in the range of degrees to 10 degrees. If the angle is smaller than 3 degrees, it is not possible to effectively set the flag 2 in the horizontal direction from the pole 1 against the flag 2 hanging down by gravity. If the angle of inclination exceeds 10 °, only a part of the flag 2 close to the pole 1 is blown up, and the whole flag 2 cannot be blown up against gravity. The reason why the middle and lowermost air ejection nozzles 15a, 16a, 15b, 16b have a larger divergence angle and a larger suppression angle than the uppermost air ejection nozzles 15, 16 are as follows. Due to the following: That is, the flag 2 hangs down to the lower position in the windless state, and as a result, the effective thickness of the flag 2 is reduced at the uppermost position and smaller at the uppermost position by blowing up at a large divergence angle at the middle and lowermost positions. Blowing up at the spread angle can make the flag 2 fly more effectively. In the middle stage and the lowermost stage, the flag 2 hangs down near the pole 1 in a windless state, so that it is effective to blow up with a large angle of depression. As a result, at the uppermost stage, the flag 2 is moved from the pole 1 Since the flag 2 is located farther away, it is possible to effectively blow up the entire horizontal direction of the flag 2 by blowing up with a small angle of inclination.

The flag 2 has a horizontal length of 2100 mm and a vertical length of 1400 mm. In this case, three pairs of air ejection nozzles 15, 16, 15a, 16a, 15b, 1
6b is used. Instead of the flag 2, the flag 2a has a horizontal length of 1800 mm and a vertical length of 1200 mm. In this case also, all the air jet nozzles 15, 16, 15a, 16a, 15b, 16b are used. Is used, the flag 2a can be efficiently fluttered. Flag 2b has a horizontal length of 900 mm and a vertical length of 600
mm, but also in this case, all the air ejection nozzles 15, 16, 15a, 16a, 15
The flag 2b can be efficiently fluttered using the b and 16b. In addition, it is also possible to change the waving mode of the flag 2 and the like by selectively opening the air ejection nozzles 15 and 16.

The air volume can be adjusted in two or more stages by the adjustment switch 8 attached to the panel 3a.

Next, another embodiment will be described with reference to FIGS. FIG. 5 shows a case where the pole 1 is erected on a base portion 22 installed on the ground, and a box 5 such as a blower 5 is placed away from the pole 1. The blower 5 and the pole 1 are connected by an extended duct hose 10. The driver 6 is operated by the remote controller 20. Note that instead of using the remote controller 20, a remote switch 21 configured so that the ON / OFF switch 7 and the adjustment switch 8 can be separated from each other by wire may be used.

According to the embodiment shown in FIG. 5, the wind noise of the blower 5 and the like can be prevented from being heard at the place where the flag 2 is erected and the place where the driving device 5 is controlled. it can.

In the embodiment shown in FIG. 6, the box 3 is not separated from the pole 1 and the remote controller 20
Alternatively, an example in which the remote switch 21 is used will be described. In this case, it is not necessary to use the extended duct hose 10, and it becomes possible to remotely control the duct hose 10 indoors.

The embodiment shown in FIG. 7 shows an example in which the box 6 in which the blower 5 and the like are housed is separated and the driver 6 is operated by the ON / OFF switch 7 and the adjustment switch 8. The blower 5 and the pole 1 are connected by an extended duct hose 10. In this case, pole 1
Are erected on the base portion 22 as in the case shown in FIG.

According to the example shown in FIG. 7, it is possible to prevent the wind noise from the blower 5 from being heard at the position where the pole 1 is erected.

FIG. 8 shows still another embodiment. In FIG. 8, three poles 1 are erected in parallel. Each of the three poles 1 can be blown by a separate driver 6. 8 (a), (b),
As shown in (c), by selecting the flag 2 on the pole that blows at a constant timing in time, it is possible to create various flag display effects.

Further, the opening and closing of the air jet nozzles 15 and 16 and the like intermittently at appropriate timings can make it possible to select various patterns of the flag 2 fluttering. Thereby, it is also possible to create still another effect of displaying the flag.
