Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flag hoisting device.

[0002]

[Prior art]

 Traditionally, it was up to nature to fly the flag displayed on the pole. In addition, when displaying a flag indoors, it was carried out by hanging from the upper edge of the flag. For this reason, there was no device that could constantly fly the flag indoors or outdoors when there was no wind.

[0003]

[Problems to be solved by the device]

 However, it is ideal that the flag displayed should be open so that the contents of the flag itself can be discriminated.However, when the wind power outdoors is weak by conventional means, the flag does not fly sufficiently and there is no wind. In the case of the state, it simply remained in the hanging state. In addition, if the flag is hung in the shape of goodwill when it is displayed indoors, the comfort and beauty caused by the state of being fluttered in the wind cannot be felt. Furthermore, for safety flags and signal flags at construction sites, which are used for visually appealing and communicating, the type of flag is not known if the flag hangs in a windless state, and work safety is high. There were drawbacks such as poor efficiency and efficiency. In addition, when letting the flag fly in the natural wind, there was a problem that the flag would wind around the pole and would not be shelved due to changes in the wind direction.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is a flag raising pole in which a rope 4 is attached to an upright hollow pole 3 and a flag 7 is attached to the rope 4, and a pipe is provided on the pole 3 side. An air compressor 11 connected via 12 is provided, and a nozzle 13 for spraying the air sent from the air compressor 11 to the flag 7 is provided on the circumference of the pole 3 on the side where the flag 7 is attached. The first feature is that the pole is rotatably supported in the pole mount 2. Further, in the flag-raising pole in which the rope 4 is attached to the hollow pole 3 which is installed upright, and the flag 7 is attached to the rope 4, an air compressor 11 connected via a pipe 12 is provided on the pole 3 side, A nozzle 13 for spraying the air sent from the air compressor 11 to the flag body 7 is provided on the side of the pole 3 on the side where the flag body 7 is attached, and the hollow pole 3 is rotatably supported in the pole attachment 2, The second feature is that the wind sensor 16 and the control panel 26 that stops the operation according to the wind force are provided.

[0005]

[Action]

 Compressed air from the outside is introduced into the hollow pole 3 through the pipe 12, and the air passing through the hollow pole 3 is discharged from the opening of the nozzle 13 and is attached to the vicinity of the opening of the nozzle 13. Be sprayed on. For this reason, the flag body 7 always flies moderately. Further, if the wind sensor 16 and the control panel 26 that repeats the operation stop depending on the wind force are connected and installed side by side, the compressed air can be automatically blown from the pipe 12 only when the wind needs to be blown such as in a no-air condition. Further, since the hollow pole 3 is rotatably supported in the pole mount 2, the hollow pole 3 automatically rotates so that the side on which the flag 7 is attached faces downward when the flag 7 is swung by the natural wind. However, the flag 7 is prevented from winding around the hollow pole 3.

[0006]

【Example】

 The embodiment shown in the drawings will be described in detail below. As shown in FIGS. 1 and 2, a pole mount 2 is installed on the upper surface of a base (flag stand) 1, and a hollow pole 3 is fitted to the pole mount 2. It is supported and erected. An elevating rope 4 is attached from the upper end to the lower end in the vertical direction of the pole 3, and a flag body 7 is fastened to the ascending / descending rope 4 at its side ends 7a, 7b. The flag 7 is moved up and down by the feeding operation of 4.

A hole 8 is formed in the peripheral walls of the pole attachment 2 and the pole base end portion 3b, and a connection pipe 9 is provided so as to project on the outer periphery of the hole 8. On the other hand, an air pipe 12 is connected to the air compressor 11, and one end of the air pipe 12 is joined to the connecting pipe 9. The air sent out by the operation of the air compressor 11 is introduced into the hollow pole 3 through the air pipe 12 and the hole 8. In this case, the air compressor 11 may be embedded near the pole 3 and the air compressor 11 may be operated from an operation switch (not shown) connected to the air compressor 11.

[0008] A plurality of nozzles 13 are provided at the flag 7 raising position on the upper side of the pole 3 side by side in the vertical direction toward the side where the flag 7 is attached. The air sent from the air compressor 11 and introduced into the pole 3 rises inside the pole 3 and is ejected from the nozzle 13 to the outside. The flag 7, which is displayed at a predetermined position, flutters along the air blown from the opening of the nozzle 13. The amount of air blown by the air compressor 11 may be increased / decreased so that the fluttering force of the flag 7 can be adjusted arbitrarily.

3 and 4 show an embodiment in which a wind sensor 16 is installed on the pole side to automatically control the amount of air blown from the air conditioner presser 11 according to the wind force. A box body 17 made of a cylinder having the same diameter as that of the pole 3 is placed and fixed on the pole upper end 3a, and a shaft core 18 is rotatably erected on the upper wall of the box body 17, and the shaft core 18 is lightweight. A plate blade 19 made of a member is fixed so as to rotate integrally with the shaft core 18. The upper and lower ends of the shaft core 18 are fitted and supported by the ring 21.

A permanent magnet 22 is rotatably housed in the hollow box body 17 so as to rotate integrally with a shaft core 18, and an electromagnetic coil 23 is housed around the permanent magnet 22 to form a wind sensor 16. is doing. On the other hand, a control panel 26 is installed near the air compressor 11, and the electromagnetic coil 23, the control panel 26, and the air compressor 11 are connected by wiring 27.

In such a structure, when the plate blade 19 rotates in response to the wind force, the permanent magnet 22 also rotates at the same speed as the plate blade 19 via the axis 18, so that the wind force sensor 16 causes the control panel 26 to move the wind. Can be stopped while detecting Therefore, if the strength of the wind power is below a certain standard and the flag body 7 does not swell sufficiently by the natural wind, air is blown. Conversely, if the strength of the wind power is above a certain standard, the flag is exposed to the natural wind. The control panel 26 is set so that the blowing is stopped when the body 7 flies.

FIG. 5 shows a rotatable supporting structure for the pole 3. A ring-shaped seal bearing 29 is concentrically attached to the upper end of the cylindrical pole attachment 2, and a seal bearing 30 is attached to the lower end of the pole. The pole 3 fitted to such a pole attachment 2 is rotatably provided upright via the seal bearings 29 and 30. A hole 32 for air piping is formed substantially in the center of the bottom surface of the pole fitting 2, and the air piping 12 is connected to the hole 32. Further, the electric wire 27 extending from the electromagnetic coil 23 is focused on a ring-shaped rotating brush 33 joined and installed on the peripheral wall surface of the hole 32 and introduced into the air pipe 12. If the pole 3 can be freely turned in this way, the pole 3 can be turned so that the side on which the flag 7 is attached faces leeward. Therefore, the flag 7 winds around the pole 3 due to a change in the wind direction, and the flag 7 falls. It is possible to eliminate the situation where it becomes loose. The present invention can be used for carp roaming, etc. in addition to the flag 7.

[0013]

[Effect of device]

 According to the present invention configured as described above, when a flag is displayed indoors or outdoors, the flag can always be made to flutter regardless of the presence or absence of the natural wind, and an ideal flag waving in the wind. Can be displayed. In addition, for flags such as safety flags and signal flags at construction sites that are visually appealing and communicated, the flag is constantly fluttered to make it easier to identify the type of flag. It is possible to improve the safety and efficiency of. Furthermore, by connecting the wind sensor and the control panel, it is possible to blow air only when it is necessary, thus reducing costs. In addition, since the hollow pole automatically rotates according to the wind direction, the problem that the flag body 7 winds around the hollow pole 3 due to a change in the wind direction can be solved.
