Can be given. Also, the present invention relates toTableSince the display device has a simple structure and the members constituting the display device are inexpensive, it is possible to obtain an unprecedented dynamic decoration effect at an extremely low cost.
[0008]
In addition, when the internal space is a sealed space, because the internal pressure in the space is increased by the air sent by the blowing means, the amount of air is gradually reduced, the swirling airflow is weakened, According to the present invention, since the air discharge port is provided, air in the internal space is appropriately discharged from the air discharge port, and the internal pressure in the space is prevented from being increased more than necessary and the swirling airflow is prevented from being weakened. And the swirling airflow can be maintained at an appropriate strength.
[0009]
In addition, when the air discharge port is provided at least in the vicinity of the inlet, the air in the vicinity of the inlet receives an action of being drawn into the air flow from the air blowing means, so that the air constituting the swirling airflow The flow in the vicinity of the discharge port is not easily decelerated due to the influence of the air flow discharged from the air discharge port, thereby obtaining the effect that the flow velocity of the swirling airflow can be maintained at a desired speed..

[0012]
According to this invention, the air flow sent from the inlet port collides with the inner surface of the side member facing the inlet port, and the flow direction is changed to the direction along the inner surface. It becomes a swirling airflow that flows along the inner peripheral surface.Even in this way,Similar effects can be obtained.
[0013]
Also in this case,in frontOf the corners formed in the internal space, if an inclined plate is provided at a corner other than the corner where the inlet is provided, when the air flow direction is changed at the corner, the inclined plate In other words, the direction of air flow is changed by being guided by the inclined plate, so that there is little energy loss at the time of conversion, and a strong swirling airflow can be easily generated.
[0014]
Furthermore,If the length ratio of the long side / short side of the plate-like member is 1.0 to 1.5 / 1, the swirling airflow can be made substantially circular. Accordingly, the balloon can be caused to perform a circular motion, and a dynamic decoration effect balanced overall can be obtained.
[0015]
Also,At least one of the pair of opposing members is composed of a substantially rectangular plate-like member, and the length ratio of the long side / short side is 1.6 to 3.0 / 1, and the feeding port is Provided at approximately the center position of the side member provided on the long side of the plate-like memberMay be.

thisIf you doThe air fed through the feed port collides with the inner surface of the side member facing the feed port, and its flow direction is converted into two directions along the inner surface (referred to herein as the left-right direction). Two swirl airflows are formed, and the balloons stored in the internal space are swirled by the swirl airflows to form a set of two groups. Thereby, the dynamic decoration effect different from the above is obtained.
[0017]
Also in this case,in frontIf the four corners formed in the internal space are provided with inclined plates having both ends connected to both side members forming the corners, respectively.,SkySince the direction of the air flow is guided and converted by this inclined plate, there is little energy loss during the conversion, and a strong swirling airflow can be easily generated.
[0018]
Furthermore,By providing a diversion means facing the inlet, the air flow from the inlet can be easily diverted in two directions by the diversion means, and there is less energy loss during the diversion, which also results in a stronger flow. The swirl airflow can be easily generated.
[0019]
In addition, the present inventionThenAt least one of the pair of opposing members is formed of a substantially equilateral polygonal plate-like member having a pentagonal shape or more, and a feeding port provided in the side member surrounds a space between the pair of opposing members.

[0028]
Moreover, in this example, two air exhaust ports 18 and 18 are formed in the flat plate 3 on the indoor side. The air outlets 18 and 18 are formed so as to leave at least the outer peripheral edge of the flat plate 3. The air outlets 18 and 18 are respectively provided with nets 19 and 19 in the same manner as in the air outlets 14 and 14 described above, so that the balloons housed in the internal space are arranged. 21 is prevented from being discharged from the air discharge ports 18 and 18.
[0029]
Further, a swing plate 20 that is swingable in the direction of the arrow is attached to the indoor flat plate 3 via a hinge 20a, and an opening formed in the flat plate 3 by the swing plate 20 is attached. The part 3a is opened and closed. Further, three sliding doors 6 that are movable in the direction indicated by the arrows are provided below the indoor-side flat plate 3. By moving the sliding door 6 in the direction indicated by the arrows, the opening of the same part is opened. The part can be opened and closed.
[0030]
Further, as shown in FIG. 2, inclined plates 22 are provided at positions corresponding to the four corners of the flat plate 3. The inclined plate 22 is provided so that both ends thereof are fixed to the inner surfaces of the side members (the bottom plate 5, the pair of side plates 4, 4 and the top plates 17 and 17) and intersect the side members at approximately 45 °. Yes. The inclined plate 22 is not limited to a flat plate as shown in the figure, and may be, for example, a circular arc curved toward the corner. Further, a diversion means 23 is provided at a position of the bottom plate 5 facing the blower 11. This flow dividing means 23 is formed of a member having an outer shape of a triangular prism, and is arranged so that one outer peripheral surface faces downward and the other two surfaces are inclined as shown in FIG.
[0031]
Illumination devices 25 and 25 are provided on the mutually opposing surfaces of the side plates 4 and 4, respectively, and the interior space is illuminated by the illumination devices 25 and 25. The bottom plate 5 is provided with static electricity removing means 24, 24 between the inclined plate 22 and the flow dividing means 23. The static electricity removing means 24, 24 are provided with a plurality of nappings made of conductive fibers, and the nappings are appropriately grounded.
[0032]
Next, this example with the above configurationTable ofThe decoration effect in the display device 1 will be described. In addition, the said air blower 11 shall be in the position shown in FIG.
[0033]
When air is fed into the internal space from the blower 11 through the feed port 13, an air flow (arrow a) from the blower 11 toward the flow dividing means 23 is generated, and then the direction of arrow a The air flow is divided into two air flows (arrow a)₁And b₁). Branched arrow a₁The air flow in the direction is then sequentially indicated by the two inclined plates 22, 22.₂Direction, arrow a₃Converted to directional airflow, arrow a₄After the air flow in the direction, the arrow a that merges with the air flow in the direction of arrow a again₅Direction of air flow, arrow a direction to a₅It becomes a swirl airflow toward the direction. On the other hand, arrow b₁Similarly, the bifurcated flow in the direction is indicated by an arrow b by two inclined plates 22 and 22 in sequence₂Direction, arrow b₃Converted into a directional air flow, arrow b₄After the air flow in the direction, the arrow b that joins the air flow in the direction of arrow a again₅Direction of air flow, arrow a direction to arrow b₅It becomes a swirl airflow toward the direction.
[0034]
If air is continuously sent from the inlet 13 into the internal space, if the internal space is a sealed space, the internal pressure in the space is increased by the air that is sent in. Although the amount of incoming air gradually decreases and the swirling airflow is weakened, according to the decoration and display device 1, the air exhaust ports 14, 14, 18, and 18 are provided. , 14, 18 and 18 are appropriately discharged, the internal pressure in the space is increased more than necessary, and the swirling airflow can be prevented from being weakened, and the swirling airflow can be maintained at an appropriate strength. .
[0035]
Thus, by the two swirling airflows generated in this way, the plurality of balloons 21 housed in the internal space become two left and right lumps as shown in FIG. The balloon 21 is swung in the direction indicated by the arrow and transmitted through the flat plate 3 made of a transparent or translucent member, and the swiveling movement of the balloon 21 is observed. Like thisTable ofAccording to the display device 1, it is possible to obtain a dynamic decoration effect that a plurality of balloons 21 swivel at a time, thereby giving a unique aesthetic feeling and a stronger impression to a viewer. Can do. Also thisTable ofSince the display device 1 has a simple structure and the members constituting the display device 1 are inexpensive, it is possible to obtain an unprecedented dynamic decoration effect at an extremely low cost.
[0036]
Incidentally, when the balloons 21 are swung as described above, they can be swung so as to perform a circular motion. For this purpose, the ratio of the short side to the long side of the flat plates 3 and 3 is 1: It is preferable that it is 1.6-3.0. In this way, the swirling airflow can be made substantially circular, and as a result, the group of balloons 21 can be caused to perform a substantially circular motion. Further, by setting the interval between the pair of flat plates 3 and 3 to be about 1.2 to 1.8 times the diameter of the largest balloon 21, the group of balloons 21 are assembled like a single plate. Can be swung regularly. On the other hand, when the interval is set to about 2.2 to 3 times the diameter of the largest balloon 21, the group of balloons 21 performs a swivel movement as a whole and individually performs an irregular movement. Expresses a different decoration and beauty.
[0037]
Moreover, in this example, since the air discharge ports 14 and 14 are provided on both sides of the inlet 13 so as to be adjacent thereto, the air in the vicinity of the inlet 13 is changed to the air flow in the direction indicated by the arrow a from the blower 11. Receiving the effect of being drawn. For this reason, the arrow a constituting the swirling airflow₄Direction and arrow a₅Directional flow velocity and arrow b₄Direction and arrow indication b₅The flow velocity in the direction is less likely to be decelerated under the influence of the air flow discharged from the air discharge ports 14 and 14, thereby obtaining the effect that the flow velocity of the swirling airflow can be maintained at a desired speed. Further, since the air discharge ports 18 and 18 are formed in the vicinity of the turning center of the swirling airflow so as to leave the outer peripheral edge of the flat plate 3, even with such a configuration, the flow velocity of the swirling airflow is also increased. Can be maintained at a desired speed. That is, the part where the flow velocity of the swirling airflow is the fastest is the outer portion, and the central portion has a relatively low flow velocity. Therefore, even if the central portion is opened, the flow velocity of the swirling airflow is hardly affected. If the air supply speed from the blower 11 is too strong, the flow rate of the air flow discharged from the air discharge ports 14, 14, 18, 18 increases, and the balloon 21 is sucked to the same part. Sometimes. Therefore, the opening area of the air discharge ports 14, 14, 18, 18 needs to be an opening area that does not cause such inconvenience..
[0038]
Further, in this example, since the interior space is illuminated by the illumination means 25, the balloons 21 that turn and move are successively illuminated by this illumination, and the effect that the dynamic decoration effect is enhanced is obtained. It is done. If a black light is used for the illumination means 25 and a fluorescent color is used for the balloon 21, the balloon is lifted and projected, and a decoration effect different from the above is obtained. Furthermore, the neon flash can be made to flash in time with the music, so that a different decoration effect can be obtained.
[0039]
Further, as described above, the flat plate 3 may be formed of a mirror-like one, and in this way, the balloon 21 that turns and moves is reflected on the mirror surface to increase the bustle, and also in this respect, the dynamic decoration effect is enhanced. be able to. Further, the mirror-like flat plate 3 may be formed with corrugations (corrugated plate) or other irregularities so that the reflected image differs depending on the viewing position. In addition, as another example in which the same effect as these can be obtained, a mirror-like member disposed outside the transparent flat plate 3 can be considered.
[0040]
In this example, the blower 11 is provided so as to be swingable in the direction of arrow A. When the blower 11 is swung in the direction of arrow A, the flow velocity of the swirl airflow on the side toward the blower 11 of the two swirl airflows increases and the balloon 21 swirls violently, while the flow velocity of the other swirl airflow On the other hand, the balloon 21 is slowly weakened and swivels slowly, and the swivel movement of the balloon 21 can be changed. Therefore, if this is done, a more dynamic decorative effect can be enhanced.
[0041]
In addition, the balloons 21 that are swiveling easily come into frictional contact with each other and easily generate static electricity, which may cause a problem that they are attracted to each other and move slowly. In this example, the static electricity removing means 24 is in the space. Therefore, when the balloon 21 is in contact with the static electricity removing means 24 during movement, the charged static electricity can be removed, and the occurrence of such a problem can be prevented. Therefore, the balloon 21 can be pivoted and moved vigorously for a long time. In addition, this static electricity removal means 24 can also be comprised from a humidifier other than the structure mentioned above.
[0042]
Also, this example provided in this wayTable ofAccording to the display device 1, as described above, since the internal pressure in the internal space is increased by the air fed by the blower 11, the internal air is discharged from the opening 3 a by opening the swing plate 20. At the same time, the balloon 21 is also discharged from the same part. Therefore, the balloon 21 inside can be easily taken out by opening the swing plate 20 as necessary. As a result, the stored balloon 21 can be quickly exchanged for one having a different shape or color, and the decoration effect obtained from the apparatus 1 can be instantly changed to a different one. In this sense, the swing plate 21 is preferably provided in a portion where the flow velocity of the swirling airflow is high. Needless to say, the swing plate 20 can be stopped in a closed state. Further, the stored balloons 21 may burst due to frictional contact between the balloons 21. In this case, the flat plate 3ofThis can be easily removed by opening the sliding door 6 provided in the lower part.
[0043]
The first embodiment of the present invention has been described above.TableAlthough the display device 1 has been described, the inclined plate 22 and the diverting means 23 described above are not particularly required to provide a swirling airflow having an appropriate flow velocity. That is, if the inclined plate 22 and the diverting means 23 are provided, a swirling airflow with a higher flow velocity can be generated. However, even if this is not used, it is sent from the inlet 13 although there is some energy loss. The air sequentially collides with the bottom plate 5, the side plates 4, 4 and the top plates 17, 17 to form the swirling airflow described above. Therefore, when the flow velocity of the air sent in is sufficiently high, it is not necessary to provide the inclined plate 22 or the diverting means 23 in particular, or these may be appropriately selectively disposed as necessary.
[0044]
Moreover, in this example, although the one ventilation means 11 was provided in the upper-side approximate center part of the flat plates 3 and 3, the number and position of the ventilation means 11 provided are not restricted to this, For example, it shows in FIG. As shown in FIG. 4, this is disposed at one upper side corner of the flat plate 3 or at both upper corners of the flat plate 3 as shown in FIG. This may be disposed at the lower end portion of the side plate 4 or may be disposed at the lower end portions of both side plates 4 so as to face each other.
[0045]
Shown in FIG.TableThe display device 1 'is shown in FIG.TableThe display device 1 is configured so as to form a substantially right half. Therefore, the same components are denoted by the same reference numerals, and detailed description thereof is omitted. ThisTable ofIn the display device 1 ′, if the ratio of the short side to the long side of the flat plates 3 and 3 is set to 1: 1.0 to 1.5, the swirling airflow can be made substantially circular. The group of balloons 21 can be caused to perform a substantially circular motion. When the blower 11 is swung in the direction indicated by the arrow A, the group of balloons 21 are agitated and moved violently and irregularly. Accordingly, by appropriately driving the blower 11, regular movement and irregular movement can be arbitrarily performed, and a variety of decorative effects can be obtained.
[0046]

ThisTable ofAlso in the display device 1 ″, the same components as those of the decoration / display device 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
[0047]
Moreover, in this example, although the flat plates 3 and 3 were used as a pair of opposing member, it is not restricted to such a board | plate material, In addition to this, for example, a sheet | seatMaterialCan be used. In this case, it is preferable to provide a framework on the outer periphery of the sheet material in order to form and maintain a predetermined shape. Moreover, although the air blower 11 provided with the wing body was illustrated as the air blowing means, the present invention is not limited to this, and a mechanism that includes a compressor, an air supply pipe, a switching valve, a jet nozzle, and the like, and sends compressed air into the internal space. May be adopted.
