JPH0662140U - Flag raising pole - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] In a stadium where there is no wind, flags such as the national flag are fluttered so that the pattern can be seen, and at the same time, the feeling that the flag is swaying in the wind is created. [Structure] The pole 17 is hollow, air is allowed to pass through the pole 17, an air outlet is provided in the upper portion of the pole 17, and a blower 9 is attached to the lower side.
Further, the wind pressure sensor 15 senses the direction of the natural wind, the information is processed by the motor control circuit 12, the motor 13 is rotated, and the direction of the pole 17 is changed to the direction that matches the natural wind direction. be able to.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flag hoisting pole used in a sports venue or the like.

[0002]

[Prior art]

 Flags displayed at stadiums and other places were hanging down along the pole when there was no wind. At indoor stadiums, etc., the flag was intentionally displayed with the flag open.

[0003]

[Problems to be solved by the device]

 When the flag was displayed without wind, the flag was hanging and the flag pattern was not visible. Also, indoors, where the flag was intentionally displayed with the flag open, lacked the feeling of fluttering due to the wind.

[0004]

[Means for Solving the Problems]

 The flag is displayed by sending an appropriate amount of air to the flag and constantly hitting it.

[0005]

[Action]

 Air is sent through the hoisting pole, which is blown out of the nozzle at the top of the pole and hits the flag directly.

[0006]

【Example】

 It will be described with reference to the drawings. As shown in FIG. 1, there is a foundation pole 4 fixed by an anchor bolt 10 on a foundation 11, which has a bearing 7 for receiving and supporting the pole 17, and a bearing 5 for smoothing the rotation of the pole 17. Is built in.

The pole 17 has a gear 6 at the bottom, which is rotated by a gear 16 attached to a motor 13, and nozzles 18 and 19 for blowing air are attached to the top.

The motor 13 processes the wind direction sensed by the wind pressure sensor 15 by the motor control circuit 12 and rotates by the required number.

As shown in FIG. 2, the air sent from the blower 9 passes through the blower tube 8, the cavity of the base pole 4 and the cavity of the pole 17 in this order, and is applied to the flag 3 from the nozzles 18 and 19.

At that time, since it is unnatural that the flag flutters in a direction different from the natural wind direction, the wind pressure sensor 15 senses the natural wind direction and sends the information to the motor control circuit 12, and the nozzles 18, 19 And the flag 3 rotates the motor 13 and the pole 17 so that the flag 3 faces the leeward direction.

By these operations, the flag 3 flutters even in a windless state, and flutters in the leeward direction even if there is a natural wind.

Since there is no natural wind when indoors, it is only necessary for the flag to flutter in a fixed direction, so there is no need to rotate the pole 17. Therefore, as shown in FIG. 3, a mechanism for rotating the pole 17 is unnecessary.

[0013]

[Effect of device]

 Since the present invention is constructed as described above, it is possible to make the flag flutter in a direction corresponding to the wind even when there is no wind in the outdoor stadium or when there is natural wind. Even in the case of indoor stadiums, the flag can be made to flutter in a fixed direction at all times, and in either case, the effect of enhancing the atmosphere of the venue can be expected.

Claims (2)

[Scope of utility model registration request] 1. A flag-raising pole capable of blowing a stream of air from an air outlet attached to the pole so that the flag can be fluttered even when there is no wind. 2. A flag-raising pole capable of changing the direction in which the flag and air are blown in order to cause the flag to flutter in a direction according to the direction of the natural wind, depending on the direction of the wind.
