Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting pole, and more particularly to a hoisting pole suitable for hoisting a national flag or the like indoors.

[0002]

2. Description of the Related Art Conventionally, poles for displaying flags such as national flags and company flags have been provided on various stadiums, high-rise buildings or roofs of government offices. Then, a method of displaying a predetermined flag on this pole to symbolically represent the competition organizer or company is adopted.

As a general hoisting pole, a pole having a predetermined axial length is erected on the ground or on a rooftop, and a pulley around which a rope for hoisting a flag is wound on the upper end side of the pole. It is known that is provided.

[0004]

However, in a conventionally known pole, when the flag is displayed, if the wind is blowing to some extent, the flag may flutter in the leeward direction. It is possible, but in the windless state, there was a problem that the flag drastically hung down.

In this case, since the marks, characters and the like represented by the flag are not externally represented, there is a disadvantage that the representation effect inherent in the flag is lost.

[0006] By the way, as seen in a gymnasium or a stadium, in an all-weather gymnasium or the like, it is inevitable that there is no wind inside the facility, so in this case it is impossible to flutter the flag. For this reason, there has been seen a method in which a support arm arranged in a direction orthogonal to the display pole is provided on the upper edge of the flag and the flag is hung from the support arm.

As described above, by suspending the flag on the arm, it is possible to certainly represent the mark or the character of the flag, but to create a natural state in which the flag is flowing by the wind. It was something I couldn't expect.

[0008]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to the various inconveniences in the prior art.
Even if the natural wind is not obtained, the flag can be constantly fluttered with a small amount of air supply, and the characters displayed on the flag,
It is to provide a hoisting pole that can clearly show marks and the like on the outside.

[0009]

Therefore, a hoisting pole according to the present invention is a pole for hoisting an object to be hoisted such as a flag, and an air outlet is provided along a vertical region of the pole on which the object is hoisted. And at least one discharge port of at least one air supply pipe connected to a predetermined air supply source is disposed in the vicinity of this air discharge port, and the air discharged from this air supply pipe blows out the air. The technique is such that it can be blown out from the mouth toward the outside of the pole. This is intended to achieve the above-mentioned object.

[0010]

When the flag is displayed, the air supplied from the air supply source is supplied through the air supply pipe into the upper portion of the pole. The air thus supplied is blown out from the air outlet, so that the air pressure blows the flag toward the air blowing direction. At this time, when the pole is formed in the upper and lower halves and a flange with a hole is interposed between the upper portion and the lower portion, the volume in the upper portion can be reduced, and therefore, a small amount of air can be obtained. The blown air pressure can be favorably maintained even with the supply amount.

Embodiments of the present invention will now be described in detail with reference to the drawings.

1 to 5 show a first embodiment of the present invention. Here, FIG. 1 shows the overall configuration of the present embodiment, and FIG. 2 shows a front view of the main parts thereof. 3 and 4 are cross-sectional views taken along the lines AA and BB of FIG. 2, respectively, and FIG. 5 is a cross-sectional view of the joint region between the upper portion and the lower portion of the pole. There is. In these figures, a pole 11 is erected upward on the display platform 10. The pole 10 is configured to have a hollow cylindrical shape and has an upper portion 1
1A and a lower part 11B are formed in two parts, and a decorative ball 12 is fixed to the upper end of the upper part 11A.

A bracket 15 is projectingly provided on the outer peripheral portion of the upper portion 11A located immediately below the decorative ball 12, and a pulley 16 is rotatable on the bracket 15 as shown in FIG. The rope 16 is supported by the rope 16 and the flag 20 which is the object to be hung is attached to the pulley 16.
1 is wound so that the flag 20 can be moved up and down.

From the position directly below the pulley 16, a plurality of holes 25 each having the same opening diameter and functioning as air outlets are formed in two rows along the vertical direction of the pole 11. There is. The vertical regions forming these holes 25 are provided so as to correspond to the vertical size of the hung object.

The holes 25 are, as shown in FIG.
A hole 25 in a certain area on the decorative ball 12 side is formed in a direction substantially orthogonal to the axial direction of the pole 11, and is provided so as to be inclined so that the air blowing angle is gradually directed upward as it goes downward. Thus, the tendency of the flag 20 to hang down due to its own weight can be prevented as much as possible. Further, as shown in FIG. 4, the flag 20 is provided between the holes 25 in the circumferential direction of the pole 11 of each hole 25.
The holes 25 are provided so as to be separated from each other by an interval L such that air is blown on both sides, and the extending directions of the holes 25 are also provided in parallel with each other.

The joint between the upper portion 11A and the lower portion 11B of the pole 11 is constituted by a screw structure portion 13 as shown in FIG. A flange 29 with a hole is interposed in this joint portion in a direction orthogonal to the axial direction of the pole 11, and a discharge port 30A, which is one end of the air supply pipe 30, is connected to the hole 29A of the flange 29 with a hole. Has been done. The other end of the air supply pipe 30 is connected to a compressor 31 as an air supply source via an adjustment valve 32, and the compressed air is driven by the compressor 31 into the upper portion 11A of the pole 11 via the air supply pipe 30. It can be supplied, and can be blown out from the holes 25. In this case, a short guide tube may be attached to each hole 25 so that air is blown out in a predetermined direction. In addition, the air supply pipe 3 in this embodiment
Two 0s are used, but the number of the air supply pipes 30 may be 1 or 3 or more.

Next, the operation of this embodiment will be described.

First, the flag 20 is attached to the rope 21, and one end side of the rope 21 is pulled through the pulley 16 so that the flag 20 shown in FIG.
The flag 20 is displayed as shown in FIG.

When the compressor 31 is driven and compressed air is supplied into the upper portion 11A of the pole 11 through the air supply pipe 30, the air supplied into the upper portion 11A becomes the holes 25. As a result, it will be blown out of the pole 11.

In this way, when the air is blown out from the hole 25, the air pressure is applied to both sides of the flag 25, causing the flag 25 to flutter. At this time, before the air is blown out, the flag 20 is in a hanging state, but among the holes 25 forming the air blowing port, the hole 25 located at the lower side can blow the air upward. Since it is formed in the above, it acts to push up the hanging flag 20 upward.

Therefore, according to such an embodiment, the flag 2
Since a plurality of holes 25 are provided in the area of the pole 11 where 0 is displayed and the air can be blown out from these holes 25, the effect that the flag 20 can be swung in a predetermined direction even in a windless state is obtained. Further, as a result of such an effect, the marks, characters, and the like displayed on the flag 20 can be clearly recognized from the outside, and as a result, it is possible to obtain the effect that the representation effect of the flag 20 can be effectively exerted. Therefore, when the present embodiment is applied to an indoor stadium or the like where a windless condition is normal, the effect can be more remarkably exerted, and the arm for opening the flag 20 can be made more conventional. In addition to eliminating the need to use, etc., it gives a realistic impression that the flag 20 is naturally fluttering.

Further, in this embodiment, the pole 11 is provided in a two-part type of the upper portion 11A and the lower portion 11B, and a flange 29 with a hole is interposed at the joint between these, and the flange 29 with a hole is provided. Since the air can be supplied only to the upper side, it is expected that the pressure in the upper portion 11A can be raised at an early stage and that the flag 20 can be blown even with a small air supply amount.

Next, another embodiment of the present invention will be described.

FIG. 6 shows a second embodiment of the present invention. In the first embodiment, the holes 25 in the circumferential direction of the pole 11 extend parallel to each other. However, in this embodiment, the holes 25 intersect on the extension line of the air blowing direction. It is characterized by being drilled with a certain inclination angle.

It is possible to separately obtain the effect that the flag can be relatively flatly splayed, and it is expected that various variations can be given to the manner in which the flag 20 is splayed.

FIG. 7 shows a third embodiment of the present invention. In this embodiment, the hole 25 as an air outlet is used.
Has the same opening diameter, but is characterized by being formed more densely toward the lower side of the pole 11.

The third embodiment as described above can also obtain the same effect as that of the first embodiment, and the flag 2
It is possible to change the way 0 is made to flow.

FIG. 8 shows a fourth embodiment of the present invention. In this embodiment, the holes 25 are the poles 1 respectively.
The hole is formed in a direction orthogonal to the axial direction of No. 1, but is characterized in that the opening diameter thereof is gradually increased toward the lower side of the pole 11.

With this embodiment as well, it is possible to effectively exert the action of pushing the flag 20 upward from below.

FIG. 9 shows a fifth embodiment of the present invention, which is characterized in that the holes 25 are formed in a line. According to this, although the force that causes the flag 20 to fly is not generated as in the above-mentioned respective embodiments, when the flag 20 to be displayed is relatively small and lightweight, the flag 20 is provided even with the configuration according to the embodiment. You can get the representation effect of
Therefore, when it is applied to a relatively compact display pole, it is expected that it can be provided at low cost.

FIG. 10 shows a sixth embodiment of the present invention. In this embodiment, the air outlet is the pole 1
1. A slit 35 formed continuously along the vertical direction of 1
It is characterized by the points formed by. In this embodiment, the illustrated state has a uniform groove width, but if necessary, the upper slit 35 width may be narrowed while the lower slit 35 width may be relatively wide. It is also possible to form.

With this embodiment, the same effect as the above embodiment can be obtained, and since the slits 35 serving as the air outlets can be formed more easily, the manufacturing cost can be reduced.

As described above, the present invention can be implemented in various modes, and is not limited to the above-mentioned embodiments as long as the flag 20 can be swung. For example, the air supply may be the compressor 31
Although the compressed air is generated and is used and illustrated and explained, the piping structure that uses the exhaust air of the air conditioning equipment introduced in the indoor competition is provided, and the same action and effect can be obtained. be able to. Further, the compressor 31 is not limited to being arranged on the ground, but may be buried in the ground, whereby noise generated during operation of the compressor 31 can be eliminated.

Further, the discharge port 30A of the air supply pipe 30 arranged in the pole 11 is not limited to the position of the hole 29A of the flange 29 with the hole, but may be positioned above it. In addition, in the structure in which a plurality of air supply pipes 30 are provided, it is possible to arrange the discharge ports 30A so that the vertical positions thereof are different from each other, and the inner diameters of the air supply pipes 30 are the same or different. It is also possible to adopt a structure in which any combination of
It is also possible to adopt a device to partition the inside of the pole with a partition plate every 0 A and change the air pressure for each air supply pipe to change the way the flag flutters.

Further, a mechanism for pre-coloring the air blown out from each of the holes 25 and 35 is provided in the middle of the piping, and the colored air is blown to both sides of the flag 20 to give a decorative effect. It is possible to

Further, the object to be displayed is not limited to the flag 20 described above, and other objects such as large and small carp streamers or wind blowers are also conceivable. In this case, it is possible to cope with this without difficulty if the holes 25 are densely arranged to configure the pole 11 so that the air can be supplied into the mouth of the carp streamer. Further, the flags and carp streamers may be applied to those for dolls displayed indoors.
