Also,
In order to add liveliness to the store and make it lively, various decorations are arranged in the room.

[0003] However, all of these decorative means are static and can give a certain degree of aesthetic sense and impression to the viewer. For a familiar viewer, it is only a lazy impression, not a unique feeling or a stronger impression that can be clearly distinguished from other decorations.

[0004] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a decoration and display device that can give a unique aesthetic feeling and a stronger impression than ever before to a viewer.

[0005]

Means for Solving the Problems and the Effects The invention according to claim 1 of the present invention for achieving the above object comprises a pair of opposing members arranged substantially in parallel at regular intervals,
A side member surrounding the periphery of the space between the pair of facing members, a plurality of balloons housed in an internal space surrounded by the pair of facing members and the side members, and the side member; And a blower for blowing air into the internal space from the air inlet to generate an air flow in the internal space. The side member is provided at least in the vicinity of the air inlet and / or Alternatively, at least one of the pair of opposing members is formed of a transparent or translucent member, and an air discharge port is formed in the opposing member while leaving at least an outer peripheral edge thereof.

When air is blown into the internal space from the blower through the blower, the blown air collides with the inner surface of the side member facing the blower and the flow direction is changed to the inner surface. , Resulting in swirling airflow flowing along the inner peripheral surface of the side member. Then, the balloon accommodated in the internal space is swirled by the swirling airflow and swirls, passes through a facing member formed of a transparent or translucent member, and the swirling movement of the balloon is observed.

It can give a stronger impression. The decoration and display device according to the present invention has a simple structure,
In addition, since the members that constitute it are inexpensive, a dynamic decoration effect that has not been available can be obtained at extremely low cost.

In the case where the internal space is a closed space, the internal pressure in the space is increased by the air blown by the blowing means, so that the amount of air blown is gradually reduced and the swirling airflow is reduced. According to the present invention, since the air outlet is provided, the air in the internal space is appropriately discharged from the air outlet, so that the internal pressure in the space is unnecessarily increased and the swirling airflow is weakened. Thus, the swirling airflow can be maintained at an appropriate strength.

Further, when the air outlet is provided at least in the vicinity of the air inlet, the air near the air inlet is drawn into the air flow from the blowing means, so that a swirling air flow is formed. The flow in the vicinity of the air outlet is hardly decelerated under the influence of the air flow discharged from the air outlet, so that the flow velocity of the swirling air flow can be maintained at a desired speed. can get. Also, so that at least the outer peripheral edge thereof is left on the facing member, in other words, even when an air discharge port is formed near the turning center of the swirling airflow, the place where the flow velocity of the swirling airflow is the fastest is the outermost part. For this reason, the flow rate of the swirling airflow is relatively slow at the center portion, and even if the center portion is opened, the flow speed of the swirling airflow is hardly affected by the opening speed. The effect is obtained. If the flow velocity of the swirling airflow can be set to a desired value, it is not necessary to provide both of the air outlets, and it is sufficient to provide one of them.

Incidentally, it should be noted that, in the present invention, the inlet and the air outlet provided in the side member in the present invention are not limited to those formed by directly making holes in the side member, and those in the side member.

According to this invention, the same operation and effect as those in the first aspect of the invention can be obtained.

[0013] In this case, as in the invention according to claim 3, when the inclined plate is provided at a corner other than the corner where the inlet is provided among the corners formed in the internal space,
When the air flow direction is changed at the corner, the air flow direction is changed along the inclined plate, in other words, the air flow direction is changed by being guided by the inclined plate,
Energy loss at the time of conversion is small, and a strong swirling airflow can be easily generated.

According to a fourth aspect of the present invention, the length ratio of the long side / short side of the plate-like member in the second or third aspect of the present invention is 1.0 to 1.5 / 1.5. If 1, the swirling airflow can be made substantially circular. Therefore,
The balloon can be made to perform a circular motion, so that a well-balanced dynamic decoration effect can be obtained.

According to a fifth aspect of the present invention, at least one of the pair of opposing members in the first aspect of the present invention is formed of a substantially rectangular plate-like member, and the length of the long side / short side is set. The aspect ratio is set to 1.6 to 3.0 / 1, and the inlet is provided at a substantially central position of a side member provided at a long side portion of the plate-shaped member.

According to the present invention, the air fed through the air inlet collides with the inner surface of the side member facing the air inlet and the air flows in two directions along the inner surface (here, the left and right directions). ), And becomes two left and right swirling airflows. The balloons accommodated in the internal space are respectively swirled by the swirling airflows to form a group of two groups. Thereby, a dynamic decoration effect different from the above can be obtained.

In this case, as in the invention according to claim 6, an inclined plate having both ends connected to both side members forming the corners is provided at each of the four corners formed in the internal space. With this arrangement, the direction of air flow is guided by the inclined plate and converted by the same operation as the operation of the third aspect of the present invention. Can be easily generated.

Further, according to the invention according to claim 7, by providing a dividing means facing the inlet, the air flow from the inlet can be easily divided in two directions by the dividing means, The energy loss at the time of split flow is small, and thus a swirling airflow with a stronger flow can be easily generated.

According to an eighth aspect of the present invention, in the first aspect of the invention, at least one of the pair of opposed members is formed of a substantially pentagonal or more substantially equilateral polygonal plate-shaped member. An air inlet provided in the member is provided in the vicinity of a corner of the side member provided so as to surround the space between the pair of opposing members, and the air feeding direction of the air blowing means is adjusted by the air feeding direction. The invention according to claim 9 is characterized in that at least one of the pair of opposed members in the invention according to claim 1 has a circular shape or a direction along the other side member forming the corner portion provided with the entrance. It is characterized by comprising an elliptical plate-shaped member, and the air blowing direction of the blowing means is set to a direction along a tangential direction of the outer periphery of the plate-shaped member.

Next, the decoration effect of the decoration and display device 1 of the present embodiment having the above configuration will be described. It is assumed that the blower 11 is at the position shown in FIG.

[0033] The blower 11
When air is blown into the internal space from the
The air flow (arrow a) directed from 1 to the flow dividing means 23 is generated.
Then, the air flow in the direction of arrow a is supplied to the branching means 23.
Two more airflows (arrow a₁And b₁).

It becomes an air current.

When air is continuously fed into the internal space from the inlet 13, if the internal space is a closed space, the internal pressure in the space increases due to the air being sent. Although the amount of air supplied gradually decreases and the swirling airflow weakens, according to this decoration and display device 1, since the air outlets 14, 14, 18, and 18 are provided, the air in the internal space is filled with this air. Outlets 14, 14, 18, 18
Moderately discharged from the space, it is possible to prevent the internal pressure in the space from being increased more than necessary and the swirling airflow from being weakened,
The swirling airflow can be maintained at an appropriate strength.

As described above, the two swirling airflows generated as described above cause the plurality of balloons 21 accommodated in the internal space to form two left and right masses as shown in FIG.
The balloon 21 swirls in the direction of the arrow along each swirling air flow, passes through the flat plate 3 made of a transparent or translucent member, and observes the swirling movement of the balloon 21. As described above, according to the decoration and display device 1, a dynamic decoration effect that the plurality of balloons 21 rotate at a time can be obtained. And give a stronger impression. Further, since the decoration and display device 1 has a simple structure and the members constituting the decoration and display device 1 are inexpensive, it is possible to obtain an unprecedented dynamic decoration effect at extremely low cost.

When the balloons 21 are swiveled as described above, they can be swirled so as to make a circular motion. For this purpose, the ratio of the short side to the long side of the flat plates 3, 3 is required. Is preferably in the range of 1: 1.6 to 3.0.
With this configuration, the swirling airflow can be made substantially circular, and as a result, the group of balloons 21 can make a substantially circular motion. Also, 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 is assembled as a single plate. It can be turned regularly. On the other hand, the interval is set to 2.
When the number of balloons is about two or three times, the group of balloons 21 performs an irregular motion individually while making a swivel movement as a whole, and as a result, a decorative feeling and aesthetic feeling different from the above are expressed.

In this embodiment, the air outlets 14, 14 are
It is provided on both sides of the inlet 13 so as to be adjacent to it.
Therefore, the air near the inlet 13 is indicated by an arrow from the blower 11.
It receives the action of being drawn into the airflow in the a direction. others
Arrow a that constitutes the swirling airflow ₄Direction and arrow a₅direction

It is. Also, it is noted that the outer peripheral edge is left on the flat plate 3.
In other words, the air outlet near the center of the swirling airflow
18 and 18 are formed.
Even if the speed of the swirling airflow is maintained at a desired speed
Is obtained. That is, the swirling airflow
The place where the flow velocity is the fastest is the outer part, and the central part

The flow velocity of the air current is hardly affected by the influence. In addition, blower
If the air supply speed from 11 is too high, the air outlet
The flow velocity of the air flow discharged from 14, 14, 18, 18 is
The problem that the balloon 21 sticks to the same part
May occur. Therefore, the air outlet 1
The opening areas of 4, 14, 18, and 18 are such disadvantages.
It is necessary to have an opening area that does not cause the problem. That one
On the other hand, as long as a sufficient opening area can be secured
For example, as in this example, the air outlets 14 and 14 and the air
It is not necessary to provide both mouths 18 and 18;
Only one of them may be provided.

Further, in this embodiment, since the inside of the internal space is illuminated by the illumination means 25, the balloons 21 which are swirling are illuminated one after another by this illumination, and the dynamic decoration effect is enhanced. The effect is obtained. still,
If a black light is used for the illuminating means 25 and a fluorescent color is used for the balloon 21, the balloon is raised and projected, and a decorative effect different from the above is obtained. Furthermore,
The neon flash can also be made to flash in time with the music, thus providing a different decorative effect.

Further, as described above, the flat plate 3 may be formed of a mirror-like material. In this case, the swirling balloons 21 are reflected on the mirror surface to increase the liveliness. The effect can be enhanced. Further, a corrugated (corrugated) or other irregularities may be formed on the mirror-shaped flat plate 3 so that the reflection image differs depending on the viewing position. In addition, as another example which can obtain the same effect as these,
It is also conceivable that a mirror-like member is arranged outside the transparent flat plate 3.

In this embodiment, 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 indicated by the arrow A, the flow velocity of the swirl airflow of the two swirl airflows on the side to which the blower 11 is directed increases, and the balloon 21 swirls violently, while the flow velocity of the other swirl airflow. Conversely, the balloon 21 slowly turns and moves, so that the turning movement of the balloon 21 can be changed. Therefore, this makes it possible to further enhance the dynamic decoration effect.

Further, the balloons 21 that move in a swiveling manner are liable to generate static electricity due to frictional contact with each other, and this may cause a problem in that the balloons 21 are attracted to each other and the movement is slowed down. Since the removing means 24 is provided, the charged static electricity can be removed by contacting the static electricity removing means 24 while the balloon 21 is moving, thereby preventing such a problem from occurring. . Therefore, the balloon 21 can be vigorously swiveled for a long time. Incidentally, the static electricity removing means 24 may be constituted by a humidifier or the like in addition to the above-mentioned constitution.

The decoration of the present example provided as described above,
According to the display device 1, as described above, since the internal pressure in the internal space is increased by the air supplied by the blower 11, the internal air is discharged from the opening 3a by opening the rocking plate 20. And balloon 2 from the same department
1 is also discharged. Therefore, by opening the rocking plate 20 as necessary, the internal balloon 21 can be easily taken out. Thereby, the stored balloons 21 can be quickly replaced with ones having different shapes and colors, and the decorative effect obtained from the present apparatus 1 can be instantly changed to a different one. In this sense, it is preferable that the oscillating plate 21 be provided at a portion where the velocity of the swirling airflow is high. Needless to say, the swinging plate 20 can be stopped in a closed state. In addition, the stored balloon 2
(1) There is a case where this is ruptured due to mutual frictional contact or the like. In this case, it can be easily removed by opening the sliding door 6 provided at the lower part of the flat plate 3.

As described above, the decoration and display device 1 according to the first embodiment of the present invention has been described.
2 and the diversion means 23 are not particularly required to provide a swirling airflow having an appropriate flow velocity. In other words, if the inclined plate 22 and the flow dividing means 23 are provided, a swirling airflow having a higher flow velocity can be generated.
The air fed from 3 collides with the bottom plate 5, the side plates 4, 4 and the top plates 17, 17 sequentially to form the above-mentioned swirling airflow. Therefore, when the flow velocity of the air to be sent is sufficiently high, it is not necessary to particularly provide the inclined plate 22 and the dividing means 23, or these may be selectively provided as needed.

In this embodiment, one blower 11 is provided substantially at the center of the upper sides of the flat plates 3 and 3. However, the number and position of the blowers 11 are not limited to this. As shown in FIG. 3, this is provided at one upper corner of the flat plate 3, or as shown in FIG. 4, it is provided at both upper corners of the flat plate 3, or not particularly shown. However, it may be arranged at the lower end of one side plate 4 or may be arranged at the lower end of both side plates 4 such that they face each other.

The same components are denoted by the same reference numerals, and detailed description thereof will be omitted. In this decoration and display device 1 ',
The ratio of the short side to the long side of the flat plates 3, 3 is 1: 1.0 to 1.
If the number is set to 5, the swirling airflow can be made substantially circular, and as a result, the group of balloons 21 can make a substantially circular motion. Further, when the blower 11 is swung in the direction of arrow A, the group of balloons 21 is agitated and moves violently and irregularly. Therefore, by driving the blower 11 appropriately, regular or irregular movement can be arbitrarily performed, and a variety of decorative effects can be obtained.

The decoration and display device 1 ″ shown in FIG.

It is preferable to provide a skeleton on the outer periphery of the sheet material for holding. Further, as the blowing means, a blower 11 having a wing body has been exemplified, but the blowing means is not limited to this, and is constituted by a compressor, an air supply pipe, a switching valve, an ejection nozzle, etc., and a mechanism for sending compressed air into the internal space. May be adopted.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 5, the decoration and display device 30 of the present embodiment is the same as that of FIG.
The display device 1 has substantially the same configuration as the decoration and display device 1 shown in FIG. 2, and therefore, the same components are denoted by the same reference numerals and detailed description thereof will be omitted.

Conversely, when air is fed into each of the partition spaces only from the other air supply pipe 44, a swirling airflow is generated in the opposite direction to that described above, and the balloon 47 is swirled around in the opposite direction. Therefore, by appropriately controlling the switching operation of the switching valve, it is possible to sequentially reverse the turning direction of the balloon 47 or set a different turning direction for each partition space. Decorative effect can be enhanced. For example, if the turning direction is changed in accordance with music or the like, a decorative effect full of hobby can be obtained. In this case, the amount of air blown per hour by the blower 11 can be varied.

In this embodiment, the same modifications as those in the first embodiment can be adopted to the extent permitted.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIGS. FIG.
Is a front view showing the decoration and display device according to the present embodiment, and FIG. 8 is a side view of the decoration and display device in an arrow B direction.

As shown in FIGS. 7 and 8, this decoration / display device 50 has a hollow cylindrical main body 51 having one open end.
A plurality of balloons (not shown) housed in the main body 51; and air supply pipes 52, 52 connected to the outer peripheral surface of the main body 51 and supplying air along a tangential direction of the outer periphery. ing. The main body 51 is transparent or translucent at least on its end face side, and has a
4 are formed. At the end of the main body 51 on the opening side, a suction means 55 is provided, and by attaching the suction means 55 to a wall surface of a building, a window glass, a floor surface or a ceiling surface 56, the decoration, The display device 50 can be installed on these. Further, each air supply pipe 44 is connected to a compressed air supply means (not shown) such as a compressor via a switching valve (not shown) provided correspondingly.
By appropriately switching this switching valve (not shown) by a control device (not shown), air is supplied from the air supply pipe 44 into the partition space, or the supply is stopped. .

Thus, according to the decoration and display device 50, the switching valve is switched so that, for example, only one of the two air supply pipes 52 is provided in the main body 51. When air is supplied to the main body 51, the supplied air is guided by the inner peripheral surface of the main body 51 and easily becomes a swirling airflow, and the balloon accommodated in the main body 51 is swirled and moved by the swirling airflow. The same operation and effect as in the embodiment can be obtained. Conversely, the main body 5 only from the other air supply pipe 52
When air is supplied into the airbag 1, a swirling airflow is generated in the opposite direction to the above, and the balloon swirls around in the opposite direction. Therefore, by appropriately controlling the switching operation of the switching valve,
The turning direction of the balloon can be sequentially reversed, and the dynamic decoration effect can be further enhanced. In addition, the adsorbing means 55 causes the wall surface of the building, the window glass, the floor surface or the ceiling surface 5.
Since the decoration and display device 50 is engaged with the display device 6, the installation thereof is extremely easy.

When air flows out of the gap between the main body 51 and the wall surface or the ceiling surface 56, the flow velocity of the swirling airflow may be weakened. In this case, as shown by a two-dot chain line in FIG. It is preferable that a flange portion 57 is formed on the inner peripheral edge of the main body 51 so as to prevent the outflow of the air by the flange portion 57.

In this example, the main body 51 is formed as a hollow cylindrical body. However, the same effect can be obtained by forming the main body 51 into a hollow equilateral polygonal column. In this case, the air supply pipe 52 may be connected to the outer peripheral corner of the equilateral polygonal column, and the air supply direction may be set to a direction along one surface that intersects the outer peripheral surface where the connection portion is provided. In this way, the air that has been sent can be moved along the inner peripheral surface of the polygonal prism,
This can be easily turned into a swirling airflow.

Needless to say, the same modification as in the above-described first embodiment can be adopted within the permissible range in this embodiment.
