  The intermediate wall 16 is a wall located above the window region 40, and separates the image projection chamber 1 and the blowout space 2 from the external space. The height at which the intermediate wall 16 is provided is substantially the same as that of the ceiling portion 19 on the first floor. As shown in FIG. 2, when the lifting screen 14 is lowered into the image projection chamber 1, the intermediate wall 16 is hidden behind the lifting screen 14, but as will be described later, the lifting screen 14 reaches the blowout space 2. When raised, the intermediate wall 16 can be visually recognized from the inside of the image projection chamber 1.

  The upper wall 17 is a wall located below the blowout ceiling portion 18 and separates the blowout space 2 from the external space. The upper wall 17 is hidden by the suspended ceiling 10 and the elevating screen 14 when the elevating screen 14 is lowered to the inside of the image projecting room 1. The vicinity of the lower end of the upper wall 17 can be visually recognized.

  The blowout ceiling portion 18 is a ceiling that covers the upper portions of the blowout space 2 and the storage space 3, and is a ceiling corresponding to the second floor portion of the exhibition house 100. The blow-out ceiling portion 18 is hidden from the suspended ceiling 10 and the ceiling portion 19 on the first floor and is not visible from the inside of the image projection chamber 1, and a suspension beam 32 and the like described later are suspended and held by an anchor.

  The first-floor ceiling portion 19 is a ceiling of a region of the image projection room 1 on the side opposite to the window region 40 where the suspended ceiling 10 is not provided. A storage space 3 is formed above the ceiling 19 of the first floor, and a motor unit 31 and a drum unit 34, which will be described later, are placed on the storage space 3. The partition 19a is a partition that is erected on the edge of the ceiling 19 of the first floor, and separates the blow-out space 2 above the suspended ceiling 10 and the storage space 3 above the ceiling 19 of the first floor. There is.

  As shown in FIG. 2, the suspended ceiling 10 is provided so as to cover substantially the entire blow-out space 2 from the intermediate wall 16 to the ceiling 19 of the first floor, and the lifting screen 14 is provided from the gap between the suspended ceiling 10 and the intermediate wall 16. Is lowered into the image projection room 1. Further, when the suspended ceiling 10 is at the lowest position, the height from the floor surface 11 is H1, which is substantially flush with the ceiling portion 19 on the first floor. Thereby, in the state where the image is projected on the three surfaces in the image projection room 1, the suspended ceiling 10 and the first-floor ceiling portion 19 are recognized as one ceiling surface.

  When the surface finish of the intermediate wall 16 is the same as that of the sleeve walls 12L and 12R, the sleeve walls 12L and 12R surrounding the window region 40 and the intermediate wall 16 can have a unified feeling as an integral wall. When the surface finish of the intermediate wall 16 is the same as that of the ceiling 19 of the first floor and the suspended ceiling 10, the intermediate wall 16 can be made to be conscious as a part of the ceiling of the image projection room 1.

  As shown in FIG. 2, a motor unit 31, a suspension beam 32, and a self-locking device 33 are arranged above the suspended ceiling 10 and the first-floor ceiling unit 19, and the drum unit 34 and the wires 35 are arranged. The suspended ceiling 10 is suspended by a suspension bolt 36 so that it can be moved up and down.

  The motor unit 31 is a power source that is connected to a power source (not shown) and a control device and rotates the drum unit 34 in accordance with a control signal from the control device. The suspension beam 32 is a beam that extends from the blow-out space 2 to the storage space 3, and is suspended from the blow-out ceiling portion 18 by an anchor or the like. The suspension beam 32 is provided with a former pulley and a branch pulley, and the wire 35 is wired along the suspension beam 32.

  The self-locking device 33 is a safety device for preventing the suspended ceiling 10 from falling, and is suspended on the blowout ceiling by an anchor or the like. In the self-locking device 33, the tip of the rope is connected to the back side of the suspended ceiling 10, and when the suspended ceiling 10 is suddenly dropped, a mechanical deceleration mechanism or a stop mechanism is activated to display the suspended ceiling 10 as an image. It is prevented from falling into the projection chamber 1.

  The drum unit 34 is a cylindrical device that is driven by the power supplied by the motor unit 31, and winds and sends out the wire 35 by rotating in the forward and reverse directions. The wire 35 has one end connected to the suspension bolt 36 and the other end wound around the drum portion 34. As shown in FIG. 2, the wire 35 is wired from the drum portion 34 through the original pulley and the branch pulley of the suspension beam 32, and is vertically lowered from the branch pulley to suspend the suspended ceiling 10 with the suspension bolts 36. I'm lowering it. The suspension bolt 36 is a bolt fixed to the back surface of the suspended ceiling 10, and one end of the wire 35 is connected to the suspension bolt 36.

  Further, a window region 40 is provided on the back side of the elevating screen 14, and an upper window region 41 is provided above the window region 40 via the intermediate wall 16. The elevating screen 14 extends downward from the screen case 50, and the tension bar 51 attached to the lower end reaches the floor surface 11. Therefore, when the image is projected on the three surfaces of the image projection chamber 1, the window region 40, the intermediate wall 16 and the upper window region 41 are hidden behind the lifting screen 14.

  The window region 40 is a window provided between the sleeve walls 12R and 12L and separates the image projection chamber 1 from the external space. For the window region 40, a glass window or sash used in a normal house can be used, and various structures such as a sweep window can be used.

  The upper window region 41 is a window provided between the intermediate wall 16 and the upper wall 17, and separates the blowout space 2 and the external space. The upper window region 41 may also be a glass window or sash used in a normal house. Further, by configuring the window region 40 and the upper window region 41 with the same material, even if the suspended ceiling 10 is raised to the highest position as will be described later, the uniformity of the space of the image projection chamber 1 is maintained. Can have

  The screen case 50 is a device that winds up and houses the elevating screen 14, and is connected to a power supply and a control device, and winds up and down the elevating screen 14 according to a control signal. The tension bar 51 is a cylindrical member attached to the lower end over the entire width of the elevating screen 14, and applies a predetermined tension to the elevating screen 14 to ensure flatness.

  As shown in FIGS. 1 and 2, when the suspended ceiling 10 is lowered to the lowest position, the height H1 from the floor surface 11 is the same as the height of the first floor ceiling portion 19, for example, about 2400 mm. The ceiling height of a room in a general house Further, the floor surface 11, the sleeve walls 12R and 12L, the side walls 13 and 15, the suspended ceiling 10, the intermediate wall 16, and the first-floor ceiling portion 19 are finished to be used in a normal house. Therefore, when the elevating screen 14 is lowered to the lowest position, the visitor recognizes the image projection room 1 as a living room space similar to the other rooms of the exhibition house 100, and links with the experience in the living space. And the effect of production is improved.

  FIG. 4 is a schematic plan view showing the interior of the room in which the image is projected. In the image projection room 1, image projection devices 20a to 20d such as projectors are arranged. The straight line shown by the broken line in the figure indicates the range of the image light projected from each of the image projection devices 20a to 20d. The method for fixing the image projection devices 20a to 20d in the image projection chamber 1 is not limited, and the suspended ceiling 10 or the first floor ceiling portion 19 may be hung by using a bracket, and any wall surface of the image projection chamber 1 may be used. It may be fixed by using a bracket, or may be placed on the floor surface 11 by using a stand.

  The image projection devices 20a to 20d are each connected to a power supply and a control device, and project an image in accordance with a control signal from the connection device. Further, the information of the image to be projected is transmitted from the control device to the image projecting devices 20a to 20d, and each of the image projecting devices 20a to 20d projects the image according to the image signal.

  In the example shown in FIG. 4, the image projecting device 20a projects an image on the side wall 13, the image projecting device 20b projects an image on the right side of the elevating screen 14 and the sleeve wall 12R, and the image projecting device 20c operates. An image is projected on the left side of the elevating screen 14 and the sleeve wall 12L, and the image projection device 20d projects an image on the side wall 15.

  At this time, the images projected by the image projection devices 20b and 20c are overlapped on the elevating screen 14. Further, the edge of the image projected by the image projector 20a is continuous with the edge of the image projected by the image projector 20c. Further, the edge of the image projected by the image projector 20d is continuous with the edge of the image projected by the image projector 20c. The control device controls the video information to be transmitted to each of the video projection devices 20a to 20d based on the overlap and continuity of the video to form one continuous video.

  As a result, the side wall 13 and the sleeve wall 12L forming the three-direction surfaces of the image projection chamber 1 are exposed from the lifting screen 14, and the lifting screen 14 and the sleeve wall 12R are exposed from the lifting screen 14. A continuous image is projected on the side wall 15. In this way, by projecting continuous images on the three surfaces of the image projection room 1, since the visitors are surrounded by the images in three directions, the immersive feeling is increased, and the effect of presentation can be improved.

  Although FIG. 4 shows an example in which four image projection devices 20a to 20d are used, images are displayed on the side walls 13 and 15, the sleeve walls 12R and 12L, and the elevating screen 14 which are the three-direction surfaces of the image projection chamber 1. Any configuration may be used as long as it can be projected. Further, although the projector is given as an example of the image projection devices 20a to 20d, a projection technique such as a mirror ball or laser projection, a projection mapping technique, or the like may be used.

  Next, the image projection chamber 1 after image projection will be described with reference to FIGS. FIG. 5 is a schematic diagram showing the interior of the room where the elevating screen 14 is being rolled up after the image projection is completed. FIG. 6 is a schematic cross-sectional view showing the state shown in FIG.

  The control device winds up the elevating screen 14 when the projection of the image using the image projection devices 20a to 20d is completed. At this time, by adjusting the timing at which the image projection ends and the timing at which the ascending / descending screen 14 starts to rise, it is possible to seamlessly change the space seamlessly.

  Moreover, it is preferable to hold the suspended ceiling 10 in a state of the height H1. As the elevating screen 14 rises, the sleeve walls 12R and 12L hidden by the elevating screen 14, the window regions 40, the garden of the external space, and the like become visible from the image projection room 1. When the window area 40 hidden behind the elevating screen 14 becomes visible, the image projection room 1 has a stronger impression of being a room in a normal house.

  While projecting an image on the three surfaces of the image projection room 1, the visitors are given the impression that they have entered the world of the projected image in the image projection room 1, but the elevator screen 14 rises when the image ends. By doing so, the window region 40 and the external space can be seen. As a result, the visitor can observe the contents of the exhibition house 100 while receiving the impression provided by the image, and the staging effect can be enhanced.

  Further, during the hoisting of the elevating screen 14 shown in FIGS. 5 and 6, since the height of the suspended ceiling 10 is H1 and does not change from that at the time of image projection, a spatial sense of unity at the time of image projection and after the end of the image is maintained. It is possible to shift to a tour of the display house 100 without feeling uncomfortable.

  FIG. 7 is a schematic diagram showing the interior of the room in which the suspended ceiling 10 is raised to the highest position. FIG. 8 is a schematic cross-sectional view showing the state shown in FIG. The height when the suspended ceiling 10 is raised to the highest position is H2. Here, the height H1 corresponds to the first ceiling height in the present invention, and the height H2 corresponds to the second ceiling height in the present invention. The upper window region is provided at a position higher than the height H1 and lower than the height H2.

  The control device starts the lifting of the suspended ceiling 10 when the lifting screen 14 is lifted above the height H1. At this time, by adjusting the ascending speed of the elevating screen 14 and the ascending speed of the suspended ceiling 10, the space can be changed seamlessly and comfortably.

  Since the lifting screen 14 is located above the height H1, it is hidden by the suspended ceiling 10 and cannot be seen from the video projection room 1. As the suspended ceiling 10 rises, the intermediate wall 16 and the upper window region 41 hidden by the suspended ceiling 10 become visible from the image projection chamber 1. After raising the suspended ceiling 10 to the highest position, the control device turns on the lighting fixture 10a.

  By changing the height of the suspended ceiling 10 from H1 to H2, the space of the image projection chamber 1 is expanded, and the feeling of liberation can be increased more than when the image is projected and when the elevating screen 14 is rolled up. Further, since the ascending / descending screen 14 and the suspended ceiling 10 are continuously performed, the line of sight of the visitor in the image projection room 1 is naturally guided to the window region 40 and above it. As a result, the presence of the intermediate wall 16 and the upper window region 41 hidden by the suspended ceiling 10 and the connection with the external space can be more strongly recognized.

  Further, since the external area can be visually recognized through the upper window area 41, a high position in the garden and the sky can be seen from the inside of the image projection chamber 1, and the feeling of liberation can be further enhanced. In this way, the control device executes a series of operations from the image projection to the raising of the elevating screen 14 to the raising of the suspended ceiling 10, so that the visitor can experience a series of scene transitions without a sense of discomfort, and the staging effect is enhanced.

  For example, when the height H1 is set to about 2400 mm, which is the ceiling height in a general house, and the height H2 is set to about 3500 mm, the visibility of a living room with a high ceiling, a sense of openness, and continuity with an outdoor space are emphasized. can do.

  As shown in FIG. 8, the screen case 50 is provided at a position higher than the height H2 at which the suspended ceiling 10 is raised to the highest position. Therefore, when the screen surface of the elevating screen 14 is rolled up to the uppermost position, the screen case 50 is hidden by the suspended ceiling 10.

  FIG. 9 is a schematic cross-sectional view showing the structures of the lifting screen 14 and the screen case 50. The screen case 50 is attached to the upper wall 17 on the blowout space 2 side, and accommodates the elevating screen 14, the tension bar 51, the light leakage prevention portion 52, and the roll portion 53 inside.

  The light leakage prevention portion 52 is made of the same material as the screen surface of the lifting screen 14, is attached to the upper wall 17 side over the entire width direction of the tension bar 51, and extends below the tension bar 51. .. By providing the light leakage prevention portion 52, even when the tension bar 51 is in contact with the floor surface 11, a slight gap between the tension bar 51 and the floor surface 11 can be blocked by the light leakage prevention portion 52, and the window region 40. Therefore, it is possible to prevent light from leaking into the image projection chamber 1. The roll portion 53 is a cylindrical member that is attached inside the screen case 50 and winds the screen surface of the elevating screen 14.

  In addition, in the display house 100, if the inside of the blowout space 2 becomes bright, the inside of the blowout space 2 is visible from the gap between the ceiling 19 of the first floor, the upper wall 17, the side walls 13 and 15, and the suspended ceiling 10, which is not preferable. When the elevating screen 14 is lowered below the upper window region 41, the elevating screen 14 covers the upper window region 41, so that light is prevented from entering the blowout space 2. Further, when the elevating screen 14 is raised above the upper window region 41, the screen case 50 can block the light entering the blowout space 2 and prevent the inside of the blowout space 2 from becoming bright.

  As described above, in the exhibition house 100 of the present invention, by projecting continuous images on the three surfaces of the image projection room 1, the visitor is surrounded by the images in the three directions, so that the immersive feeling is enhanced and the effect of production is enhanced. Can be improved. Further, in a state in which the elevating screen 14 is lowered to the lowest position, the visitor recognizes the image projection room 1 as a living room space similar to the other rooms of the exhibition house 100, and links with the experience in the living space. And the effect of production is improved.

  In addition, since the control device performs a series of operations from the image projection to the hoisting of the elevating screen 14 to the raising of the suspended ceiling 10, the visitor can experience a series of scene changes without feeling discomfort, and the staging effect is enhanced.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments obtained by appropriately combining the technical means disclosed in the different embodiments.
