This display balun (hereinafter referred to as balun) is formed into a predetermined shape with parachute cloth (nylon), vinyl sheet, or the like. At the time of the withdrawal, the air was evacuated and folded to withdraw.

[0003]

The balun has a size of, for example, 2 meters to several meters in height in order to serve as an advertising medium or a mark. Since the balun is folded many times during transportation, when the balun is expanded by a compressor or the like, the balun is expanded and then expanded. This work requires space to spread the balun, so at the event venue,
It was done before opening. Also, when retreating the balun, work was required after the event, as it needed space to fold the balun.

[0004] Since the balun is installed as it is from the start to the end of the event, its installation position is limited to a position that does not interfere with various situations during the progress of the event. Therefore, baluns cannot always be installed in the most prominent locations as advertising media and landmarks,
If installed as a part of the venue as time passes, it will not be able to fully function as an advertising medium or landmark.

[0005]

Further, each of the control cords 11, 12, 13, 14,
A plurality of baluns 15 are attached to the balun 2 in a completed state in such a manner that the baluns 2 are scattered on a line intersecting with a virtual plane parallel to the opening 5. Each control string is connected to the winding mechanism on the right side to prevent the balun 2 from being locally deformed when restricting the feeding of the balun 2 by the respective control strings or when winding up. In addition, the first to sixth control strings 11, 12, 13,
Reference numerals 14 and 15 are loosened so as not to affect the shape of the balun 2 in the illustrated state where the balun 2 is expanded to a completed shape.

The take-up mechanism 16 includes first to sixth pulleys 2.
0, 21, 22, 23, 24, 25; a motor 26 for rotating these pulleys 20, 21, 22, 23, 24, 25;
0, 21, 22, 23, 24, 25, and a clutch (not shown) for selectively transmitting to each of the pulleys 20, 21, 22,
A stopper (not shown) provided for each pulley for selectively bringing the 23, 24, 25 into a stopped state is provided. An isolation grid 27 is provided above the winding mechanism 16 to prevent the balun 2 from being damaged by touching mechanical parts such as pulleys when the balun 2 is stored in the base 4.

FIG. 3 to FIG. 8 are sectional views similar to FIG. 2 showing the procedure for inflating the balun 2 in order. FIG.
First to sixth control strings 10, 11, 12, 13, 14, 1
5 shows a state in which the winder 5 is wound by the winding mechanism 16 and the blower is operating. As shown in the drawing, the balun 2 swells only near the top, but has not yet been exposed to the outside through the opening 5 of the base 4.

FIG. 4 shows a state in which the clutch and stopper of the first pulley 20 are turned off and the first control cord 10 is loosened. The balun 2 is swelled by the supply of air from the vicinity of the top to the mounting portion of the second control string 11 when the first control string is loosened, and is pushed out from below. Is exposed to the outside through the opening 5 of. Then, as shown in FIGS. 5, 6, 7, and 8, the balun 2 has a second control string 11, a third control string 12, and a fourth control string 12.
Each time the control string 13 and the fifth control string 15 are loosened, they are pushed out from below and expanded. When the sixth control cord 16 is loosened in the state shown in FIG. 8, the completed state becomes as shown in FIG.

Note that even if the volume of the balun 2 is gradually increased, the amount of air blown by the blower is controlled so that the internal pressure of the balun 2 is kept substantially constant. Therefore, when the balun 2 expands while being pushed upward, the internal pressure does not decrease and the balun 2 expands outside the opening 5.
Is kept substantially equal to the shape of the balun 2 in the completed state.

When the balun 2 is stored, the balun 2 is wound into the base 4 by winding the balun 2 from the sixth control cord 15 in the reverse order of the procedure for inflating the balun 2. When the volume of the balun 2 gradually decreases, the internal pressure of the balun 2 rises. I try to keep it. Therefore, when the control string is pulled to pull the balun 2 into the base 4, there is no inconvenience that the internal pressure of the balun 2 increases and the balun 2 is damaged.

The control string is wound and the balun 2 is mounted on the base 4
In order to prevent the balun 2 from being deformed by the tension of the control string when being pulled into the inside, for example, as shown in FIG. , And the sixth control cord 15 is wound straight from that position, or as shown in FIG.
The fifth control string 14 is wound after the control string 14 is attached to the balun 2 below the opening 5 by winding the sixth control string 15.

FIG. 9 is a sectional view of a balun device 1 according to the second embodiment. In the second embodiment, the balun 2 is divided into the first air chamber 30, the second air chamber 31, and the third air chamber 3 from above.
2, the fourth air chamber 33, the fifth air chamber 34, the sixth air chamber 35, the seventh air chamber 36, the eighth air chamber 37, the ninth air chamber 38, and the tenth air chamber 39 Is divided into Each air chamber is connected to an air supply / discharge control mechanism 41 via a tube 40.

FIGS. 10 and 11 are sectional views similar to FIGS. 3 and 4 for explaining the procedure for expanding the balun 2. FIG. As shown in FIG. 10, the air supply / discharge control mechanism 41
As a result, air is supplied to the first air chamber 30. Next, as shown in FIG. 11, when air is supplied to the second air chamber 31, the first air chamber 30 is pushed upward. Less than,
Although illustration is omitted, air is sequentially supplied to the third to tenth air chambers, and the air chamber located on the upper side is sequentially pushed upward by the expansion of the air chamber located on the lower side, and air is supplied to all the air chambers. Is supplied, the balun 2 shown in FIG. 9 is completed. The procedure for storing the balun 2 is the reverse of the procedure for inflating the balun 2. The air is sequentially discharged from the tenth air chamber 39 and the balun 2 is stored in the base 4.

In the apparatus of the second embodiment which can control the supply of air to a plurality of air chambers, for example, the sixth air chamber 35 and the seventh
By wedge-shaped the air chamber 36 as shown in FIG. 9 and discharging the air in the sixth air chamber 35, the balun 2 can be moved from the middle as shown in FIG. it can.

The embodiments of the present invention have been described above. However, the balun device according to the present invention may have various embodiments in addition to the above-described two embodiments. In the first embodiment, a configuration is adopted in which a plurality of control strings are selectively wound by one motor, but each of the plurality of control strings may be wound by an individual motor. In this way, each control cord can be wound at a different speed. For example, when storing a portion branched in a direction different from the storage direction, the storage speed of this portion is synchronized with the entire storage speed. By that
Balun can be free from local stress.

Further, the configuration of the first embodiment may be combined with the configuration of the second embodiment. For example, when the control string is passed through the tube of the second embodiment, the control string is guided to the tube, so that the path of the control string is not limited to a straight line, and it is possible to cope with a balun having a complicated shape such as a branch. Further, the control string can give a partial movement to the balun as well as set and store the balun. For example, if the balun imitates a person having an expression such as a human, the control string can be used to partially move the mouth, eyes, and the like to change the expression.

Further, when the balun apparatus is installed outdoors, it is necessary to consider the problem of deformation and damage of the balun due to wind. In this case, the wind speed around the balun device may be measured using an anemometer, and the internal pressure of the balun may be increased when the wind speed around the balun device increases. In this way, not only the inconvenience of the balun falling down due to the effect of the wind can be avoided, but also the internal pressure of the balun can be reduced to some extent in the absence of wind to reduce the stress applied to the balun dough.

In addition, a balun device using an anemometer
When the surrounding wind speed becomes very fast, the control can be executed such that the balun is automatically stored in the base, and when the wind speed becomes slow, the balun is automatically installed again. Therefore,
A strong wind blows when the manager of the balun apparatus looks a little away from the balun apparatus, so that an unexpected situation such as the balun apparatus falling or being damaged does not occur.

[0024]

According to the display balun device of the present invention, the display balun stored in the base can be immediately inflated from the stored state, and the display balun in the expanded state can be squeezed while being squeezed. Since the display balun can be stored and stored in a conventional manner, the operation of expanding or folding the display balun for installation or removal as in the related art and the space for the operation are unnecessary.

Further, since the display balloon can be freely expanded and stored at an event venue or the like even while the event is in progress, the restrictions on the installation location are far less than those of the related art. It can be installed, and can sufficiently exhibit its function as an advertising medium and a landmark.

Further, this display balun device is
The display balun can be attracted to a person's attention by showing the expanding operation and the stored operation, so that the display balun functions more effectively as an advertising medium or a landmark.

[0027] In addition, the control of the internal pressure of the display balun and the control of the installation and storage of the display balun by a plurality of control cords are based on the partial shape of the display balun existing outside the base. Even in the middle, it is kept almost the same shape as the completed state.
Therefore, the state of the display balun during the installation or storage operation can be made to appear to rise from the inside of the base or to sink into the base, giving an impression completely different from the conventional one. .

Further, since the operation time for installation or storage can be set arbitrarily, it can also be used as an effect production device for events that progress in seconds.

In the case where the inside of the display balun is divided into a plurality of air chambers, control for installing or storing a display balun having a complicated shape can be easily performed by combining the plurality of air chambers. . In addition, since the display balun can be partially moved, the effect as an advertising medium or a mark can be dramatically improved as compared with the conventional display balun which is merely inflated.
