In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

[First Embodiment]
The first embodiment will be described with reference to FIGS. 1 and 2. The present embodiment relates to an opening / closing body device. FIG. 1 is a diagram illustrating an example of the arrangement of the opening / closing body device 1-1 according to the first embodiment, and FIG. FIG.

  As shown in FIGS. 1 and 2, the opening / closing body device 1-1 includes an opening / closing body 10, a storage unit 20, and a lighting system 30. The opening / closing body 10 opens or closes the opening 4 formed in the structure S including buildings such as buildings, houses, and warehouses. As shown in FIG. 1, a rectangular opening 4 that connects the first space 2 and the second space 3 is formed in the structure S. Even if the opening 4 communicates the space inside the structure S and the space outside the structure S, the two indoor spaces 2 and 3 inside the structure S are communicated as in the present embodiment. You may do. The passage 5 is formed across the first space 2 and the second space 3, and becomes an evacuation passage in an emergency.

  FIG. 1 shows the opening / closing body device 1-1 as viewed from the first space 2 side. The opening / closing body 10 is in an open state in which the opening 4 is normally opened, and is a fire door that is closed at any time that can automatically or manually close the opening 4 at any time. The opening / closing body device 1-1 has an automatic closing mechanism that automatically closes the opening 4 by the opening / closing body 10, and when the smoke or heat is detected, the automatic closing mechanism is activated to open the opening 4. Can be occluded.

  The opening / closing body 10 includes a first opening / closing body 11 and a second opening / closing body 12. Each of the first opening / closing body 11 and the second opening / closing body 12 is a rectangular hinged door. In the present embodiment, the opening / closing body 10 is a double hinged door.

  The storage unit 20 is configured to store the opening / closing body 10 when the opening / closing body 10 is in an open state in which the opening 4 is opened. The storage unit 20 includes a first storage unit 21 and a second storage unit 22. The first storage portion 21 and the second storage portion 22 are rectangular depressions formed in the wall portion of the structure S, respectively. In addition, the accommodating part 20 is not limited to what is formed as a hollow in a wall part. For example, the storage unit 20 may be a recessed portion of a door frame fixed to the wall surface. The first storage portion 21 is formed on a wall portion 6A on one side in the width direction across the passage 5, and the second storage portion 22 is formed on the wall portion 6B on the other side in the width direction across the passage 5. Has been.

  The first storage unit 21 is connected to the opening 4 at the end on the second space 3 side. An end portion in the width direction of the first opening / closing body 11 is pivotally supported by a rotating shaft extending in the vertical direction at a connection portion between the first storage portion 21 and the opening 4. Accordingly, the first opening / closing body 11 can freely rotate while being pivotally supported from the rotation position stored in the first storage unit 21 to the rotation position closing the opening 4. As shown in FIG. 1, the opening / closing direction of the first opening / closing body 11 is a rotational direction in which the first opening / closing body 11 is pivotally supported and rotated at the connecting portion between the first storage portion 21 and the opening 4. The first opening / closing body 11 can open or close the opening 4 by moving in the opening / closing direction. FIG. 1 shows a first opening / closing body 11 in a closed state that closes the opening 4.

  The second storage portion 22 is connected to the opening 4 at the end on the second space 3 side. An end portion in the width direction of the second opening / closing body 12 is pivotally supported by a rotating shaft extending in the vertical direction at a connection portion between the second storage portion 22 and the opening 4, and is stored in the second storage portion 22. It is possible to rotate freely while being pivotally supported from the rotational position to the rotational position where the opening 4 is closed. As shown in FIG. 1, the opening / closing direction of the second opening / closing body 12 is a rotational direction in which the second opening / closing body 12 is pivotally supported and rotated at the connecting portion between the second storage portion 22 and the opening 4. The second opening / closing body 12 can open or close the opening 4 by moving in the opening / closing direction. FIG. 1 shows the second opening / closing body 12 in an open state that is housed in the second housing portion 22 and opens the opening 4.

  In this specification, the moving direction that rotates toward the side that closes the opening 4 in the opening / closing direction of the opening / closing body 10 is referred to as the closing-side moving direction, and rotates toward the side that is stored in the storage unit 20. The moving direction is referred to as the opening-side moving direction.

  Hereinafter, the opening / closing body 10, the storage section 20, and the illumination system 30 will be described in detail by taking the first opening / closing body 11 and the first storage section 21 as an example. The configurations of the second opening / closing body 12 and the second storage portion 22 can be the same as the configurations of the first opening / closing body 11 and the first storage portion 21.

  As shown in FIG. 1, the first storage portion 21 has a predetermined wall surface 23. The predetermined wall surface 23 forms the first space 2. The first surface 11 </ b> A is a surface that forms the first space 2 by being positioned on the first space 2 side in the first opening / closing body 11 in the closed state where the first opening / closing body 11 closes the opening 4. The second surface 11B (see FIG. 2) is a surface of the first opening / closing body 11 opposite to the first surface 11A. The second surface 11 </ b> B is a surface that forms the second space 3 in the closed state of the first opening / closing body 11.

  As shown in FIG. 2, the first surface 11 </ b> A faces the predetermined wall surface 23 when the first opening / closing body 11 is stored in the first storage portion 21 in the open state. FIG. 2 shows a cross section of the first opening / closing body 11 and the first storage portion 21 in the open state.

  The storage unit 20 has a door frame 25. The door frame 25 surrounds the periphery of the opening / closing body 10 stored in the storage unit 20. The door frame 25 is a hollow member having a C-shaped cross section, and the outer peripheral side, that is, the side opposite to the side facing the stored opening / closing body 10 is opened. The door frame 25 has a plate portion that forms the first space 2 and a plate portion that faces the predetermined wall surface 23. Further, the inner peripheral surface 27 of the door frame 25 faces the outer peripheral surface 15 of the opening / closing body 10 with a predetermined distance therebetween. The width of the door frame 25 in the opening / closing direction, which is the thickness direction of the opening / closing body 10, is such that the opening / closing body 10 can be stored in the space surrounded by the inner peripheral surface 27 of the door frame 25 in the open state.

  Thus, in the open state, the opening / closing body 10 is stored in the storage unit 20 such that the outer peripheral surface 15 faces the inner peripheral surface 27 of the door frame 25 and the first surface 11A faces the predetermined wall surface 23. Is done. In other words, the open / close body 10 in the open state is inserted into a recess formed by the inner peripheral surface 27 of the door frame 25 and the predetermined wall surface 23.

  Returning to FIG. 1, the release 24 disposed on the predetermined wall surface 23 and the hook 13 disposed on the first surface 11 </ b> A of the first opening / closing body 11 have a function as an automatic closing mechanism. In normal times, the hook 13 is held by the holding device of the release 24. Here, the first opening / closing body 11 is supported so that a self-closing force that moves toward the closing side in the opening / closing direction acts by its own weight.

  The first opening / closing body 11 generates a self-closing force, for example, by being pivotally supported by an inclined support shaft. The support shaft of the first opening / closing body 11 has an inclination in which the upper end is located closer to the second storage portion 22 than the lower end. Thereby, the gravity which acts on the 1st opening-and-closing body 11 acts as a self-closing force which rotates the 1st opening-and-closing body 11 to the closing side of an opening-and-closing direction. Therefore, when the hook 13 is released, the first opening / closing body 11 can automatically turn to the closing side in the opening / closing direction to close the opening 4.

  When the sensor detects smoke or heat, the opening / closing body device 1-1 normally stops energization of the holding device of the release 24 that electrically restrains the hook 13 by energization and releases the hook 13. Alternatively, the opening 4 is automatically released by releasing the hook 13 by releasing the restraint by energizing the holding device of the release 24 that mechanically restrains the hook 13 without being normally energized. Occlude. The operation of the second opening / closing body 12 is the same. When the first opening / closing body 11 and the second opening / closing body 12 respectively close the opening 4, the entire surface of the opening 4 is closed and the opening 4 is closed. It is also possible to manually release the holding device of the release 24 to close the first opening / closing body 11 and the second opening / closing body 12.

  The first surface 11A of the first opening / closing body 11 has a phosphorescent display unit 14 containing a phosphorescent substance. The display unit 14 may be provided by applying a paint containing a phosphorescent material to the first opening / closing body 11, or a film containing the phosphorescent material may be adhered to the first opening / closing body 11. The phosphorescent material is a well-known substance that stores light from the outside and emits light, and is composed of, for example, zinc sulfide (ZnS series), strontium aluminate (SrAl2O4 series), or the like. If a preferable example of this embodiment is described in detail, the phosphorescent material has alkaline earth aluminate as a base crystal, europium (Eu) as an activator, and desprosium (Dy) or nedium (Nd) as an activator. And oxide phosphors such as CaS: Bi (purple blue light emission), CaSrS: Bi (blue light emission), ZnS: Cu (green light emission), ZnCdS: Cu (yellow to orange light emission), etc. The resulting sulfide-based phosphorescent material is powdered (generally 20 μm to 50 μm) and mixed as appropriate.

  It is preferable that the display unit 14 is disposed at a position that is easily visible on the opening / closing body 10. The display part 14 can be arrange | positioned at the upper part of the opening-closing body 10, for example. As an example, the display unit 14 may be disposed on the top of the opening / closing body 10. The display unit 14 may be disposed on the door end side of the opening / closing body 10. In other words, the display unit 14 can be arranged at a position near the center of the opening 4 in the width direction in the closed state. The display unit 14 may be arranged not only on the first surface 11A of the opening / closing body 10 but also on the second surface 11B.

  The display unit 14 displays characters (for example, “emergency exit”, “evacuation exit”, “EXIT”, and the like) and symbols indicating the purpose of use of the opening / closing body 10, and characters (for example, “pull” and “ PULL "etc.) and design. Since the display unit 14 can emit light with light stored in advance, it can be visually recognized by an evacuee or the like even when the interior lighting is turned off due to a power failure or the like in an emergency. That is, the phosphorescent display unit 14 can emit light without requiring power supply, and can be visually recognized without illumination, and thus is excellent as an emergency display means.

  Here, in the open state of the opening / closing body 10, it is difficult to sufficiently store light in the display unit 14, and FIG. 9 can store light when the display unit 14 is provided in the conventional opening / closing body device 100. It is explanatory drawing which shows that it is difficult. Although light strikes the second surface 110B forming the first space 2 in the open state, it is difficult for light to reach the first surface 110A on the back surface side. In the conventional opening / closing body device 100, since the gap G1 between the lower surface of the door frame 125 and the upper surface of the opening / closing body 110 is small, the distance between the door frame 125 and the outer peripheral surface of the opening / closing body 110 is small. It is difficult for light to reach the gap 126. Even if the light in the first space 2 reaches the gap 126, the light only hits the predetermined wall surface 123 and hardly hits the first surface 110 </ b> A. For this reason, even if the display unit 14 is provided on the first surface 110 </ b> A, it is difficult to store light in the display unit 14.

  The opening / closing body device 1-1 of the present embodiment includes an illumination system 30 that irradiates the display unit 14 with light. Thereby, phosphorescence of the display part 14 can be accelerated | stimulated in an open state, and the visibility of the display part 14 when it is set to a closed state can be ensured.

  The lighting system 30 includes a photovoltaic device 31, a lighting device 32, and a power cable 33. The photovoltaic device 31 converts light energy into electric power and outputs it. The photovoltaic device 31 includes a light receiving unit 31A. The illuminating device 32 converts light hitting the light receiving unit 31A into electric power by a solar cell or the like. The photovoltaic device 31 is disposed in the door frame 25 above the opening / closing body 10. The photovoltaic device 31 is disposed on the first space 2 side in the door frame 25, and the light receiving portion 31 </ b> A of the photovoltaic device 31 forms the first space 2.

  That is, the photovoltaic device 31 receives the light applied to the first space 2, in this embodiment, the indoor light in the first space 2, and generates power using the light. Note that light outside the structure S may hit the light receiving unit 31A through a window or the like. Since the photovoltaic power generation device 31 generates power with room light, the display unit 14 can be illuminated by the lighting device 32 even at night. In addition, the photovoltaic device 31 is not limited to what generates electric power with the light with which the 1st space 2 is irradiated. The photovoltaic device 31 may be any device that generates power using at least one of the light applied to the first space 2 and the light applied to the second space 3.

  The illumination device 32 emits light by the electric power supplied from the photovoltaic power generation device 31 and irradiates the display unit of the opening / closing body 10 stored in the storage unit 20. The illumination device 32 is connected to the photovoltaic power generation device 31 via the power cable 33 and receives power supply from the photovoltaic power generation device 31. The lighting device 32 is disposed inside the door frame 25 above the opening / closing body 10. The illumination device 32 includes a light source 32A such as an LED and a reflector 32B. The light source 32A consumes power supplied from the photovoltaic device 31 and emits light. The reflector 32B reflects light emitted from the light source 32A. The light source 32A is disposed in the reflector 32B. The reflector 32B has a hollow hemispherical shape, and the concave surface that is the inner surface faces the outer peripheral surface 15 of the opening / closing body 10 in the open state.

  The light emitted from the light source 32 </ b> A and the light emitted from the light source 32 </ b> A and reflected by the reflector 32 </ b> B are irradiated toward the opening / closing body 10 and the predetermined wall surface 23 through a through hole 25 </ b> A formed in the door frame 25. The through hole 25 </ b> A is formed in a plate portion that faces the outer peripheral surface 15 of the open / close body 10 in the open state in the door frame 25, that is, a plate portion that forms the inner peripheral surface 27 in the door frame 25. In the present embodiment, since the illumination device 32 is disposed above the opening / closing body 10, a through hole 25 </ b> A is formed in a plate portion facing the upper surface of the opening / closing body 10 in the open state in the door frame 25.

  Illumination of the storage unit 20 is illuminated by the light source 32 </ b> A, so that light storage in the display unit 14 is promoted. Part of the light emitted from the light source 32 </ b> A enters the gap 26 between the first surface 11 </ b> A of the opening / closing body 10 and the predetermined wall surface 23 and reaches the display unit 14. For example, the light emitted from the light source 32 </ b> A irradiates the display unit 14 as direct light or reflected light reflected by the predetermined wall surface 23. Thereby, the light receiving amount of the display unit 14 is increased as compared with the case where the illumination system 30 is not provided, so that the opening / closing body 10 closes the opening 4 and the first surface 11 </ b> A forms the first space 2. The visibility of the display part 14 when it becomes can be ensured. The light source 32 </ b> A emits light by the electric power generated by the light generated by the photovoltaic device 31 applied to the first space 2. For this reason, unlike the case where power is supplied from a commercial power source or the like, the light source 32A can irradiate the display unit 14 without substantially consuming energy. That is, according to the present embodiment, the visibility of the display unit 14 in the closed state can be ensured while suppressing the running cost related to the energy consumption for irradiating the display unit 14.

The illumination system 30 may supplementarily use the power of at least one of the following power supplies as the power supplied to the light source 32A.
(1) A power generator installed outdoors or outdoors.
(2) Commercial power supply.
(3) Battery.
(4) Other known power sources.
In order to suppress energy consumption, it is preferable that the amount of power supplied from these auxiliary power sources is smaller than the amount of power supplied from the photovoltaic power generator 31.

  The opening / closing body device 1-1 of the present embodiment further includes a reflecting member 40 that reflects the light emitted from the lighting device 32 toward the display unit 14. The reflection member 40 is a member that reflects light, and is disposed on the predetermined wall surface 23. The reflecting member 40 is, for example, a plate-like or film-like member, and is disposed in parallel with the predetermined wall surface 23 and the display unit 14. The reflecting member 40 is disposed at a position facing the display unit 14. The reflecting member 40 is preferably arranged so that the reflected light irradiated by the illumination device 32 and reflected by the reflecting member 40 hits at least a part of the display unit 14, and the reflected light reflected by the reflecting member 40 is displayed. It is preferable to arrange so as to hit the entire surface of the portion 14.

  The light of the illumination device 32 is reflected toward the display unit 14 by the reflecting member 40, so that the amount of light received by the display unit 14 in the open state increases. Thereby, the visibility of the display part 14 when it will be in a closed state improves. The reflection member 40 can make the light of the illumination device 32 reach the back part where the light in the gap 26 is difficult to reach. For example, when the illuminating device 32 is arranged in the upper part of the door frame 25, the reflecting member 40 can make the light of the illuminating device 32 reach below the case where the reflecting member 40 is not provided. Thereby, it can suppress that dispersion | variation comes out in the light reception amount of the display part 14 by the position of a height direction. As a result, the visibility of the display unit 14 can be improved.

  Moreover, in this embodiment, the light storage of the display part 14 is accelerated | stimulated because the clearance gap 26 between the 1st surface 11A of the opening-and-closing body 11 and the predetermined wall surface 23 is expanded. As shown in FIG. 2, the gap G <b> 2 between the first surface 11 </ b> A and the predetermined wall surface 23 is enlarged, and a large gap 26 is secured between the first surface 11 </ b> A and the reflecting member 40. As a result, the light from the lighting device 32 easily enters the gap 26, and the amount of light received by the display unit 14 can be increased. A gap G2 between the first surface 11A and the predetermined wall surface 23 is set to be larger than the thickness t of the opening / closing body 10, for example.

  Depending on the arrangement of the illumination device 32, the interval G2 of some regions in the gap 26 may be made larger than the interval G2 of other portions in the gap 26. For example, when the illumination device 32 is disposed above the opening / closing body 10 as in the present embodiment, the upper gap G2 in the gap 26 may be larger than the lower gap G2 in the gap 26. As an example, the gap G2 of the upper area including the area where the display unit 14 is disposed in the gap 26 may be larger than the gap G2 of the area below the display unit 14 in the gap 26. In addition, as a method of enlarging the gap G2, for example, the wall 6A and the wall 6B may be formed so as to recede to the back side.

  In the present embodiment, the lighting device 32 is disposed above the opening / closing body 10, but the present invention is not limited to this. The illumination device 32 may be disposed on the side of the opening / closing body 10. For example, the illumination device 32 may be disposed on the door end side or the suspension side of the opening / closing body. The lighting device 32 may be disposed below the opening / closing body 10. For example, the position of the illumination device 32 is determined according to the arrangement of the display unit 14 in the opening / closing body 10 so that the display unit 14 can appropriately receive light. Moreover, the number of the illuminating devices 32 arrange | positioned is not restricted to one, The some illuminating device 32 may be provided. When arranging a plurality of lighting devices 32, it is possible to arrange a plurality of lighting devices 32 on one side of the opening / closing body 10 or to arrange the lighting devices 32 on a plurality of sides of the opening / closing body 10. For example, the illuminating device 32 may be arrange | positioned above each of the opening-closing body 10 and the door-end side.

  Further, the lighting device 32 is not limited to being disposed on the door frame 25. The illuminating device 32 should just be suitably arrange | positioned in the accommodating part 20 so that light can be irradiated with respect to the opening / closing body 10 and the reflection member 40. FIG.

  Although the opening / closing body 10 of the present embodiment is a double swing hinge, it is not limited to this. The opening / closing body 10 may be a single swing hinged door. In addition, the opening / closing body 10 may be a sliding sliding door that is stored in a door pocket as a storage portion.

  In addition, the opening / closing body 10 is not limited to what has a function as a fire door. The present embodiment is an open / close body that opens or closes the opening 4, and is generally applicable to other than a fire door that is normally housed in the housing and closes the opening 4 at any time.

[First Modification of First Embodiment]
A first modification of the first embodiment will be described. This modification differs from the first embodiment in that the lighting device 34 is disposed on the predetermined wall surface 23. FIG. 3 is a view showing a cross-section of the main part in the up-down direction in the open state of the opening / closing body device according to this modification.

The case 81 includes a plate portion 81A that faces the wall surface 67A across the winding shaft 82, and plate portions 81B and 81C that extend from the plate portion 81A toward the wall surface 67A. The plate portions 81B and 81C face each other in the opening / closing direction with the winding shaft 82 interposed therebetween. That is, the storage space 83 is sandwiched between the plate portion 81A and the wall surface 67A in the thickness direction of the shutter curtain 50 that closes the opening 60, and is sandwiched between the plate portion 81B and the plate portion 81C in the opening / closing direction. Yes. The case 81 is closed at both ends in the width direction.

  The case 81 has an opening 81D. A pair of lintels 81E and 81F are formed on the plate portion 81C positioned in the closing direction with respect to the winding shaft 82. The lintels 81E and 81F are opposed to each other at a predetermined interval in the thickness direction to form an opening 81D. The opening 81D communicates the storage space 83 in the case 81 with the indoor spaces 61 and 62, which are spaces closer to the closing direction than the ceiling member 64.

  The winding shaft 82 is a cylindrical member, and can wind up the shutter curtain 50 on the outer peripheral surface. The storage unit 80 includes a switch (not shown) that winds or feeds the shutter curtain 50 by controlling the rotation of the winding shaft 82. When opening the opening 60, the opening / closing machine rotates the winding shaft 82 in the winding direction. The winding direction is the rotational direction indicated by the arrow Y1 in FIG. An arrow Y2 indicates a feeding direction which is a rotation direction opposite to the winding direction Y1. When the winding shaft 82 rotates in the winding direction Y1 to wind up the shutter curtain 50, the shutter curtain 50 moves in the opening direction to open the opening 60.

  The opening / closing machine has a brake that restricts the rotation of the winding shaft 82. The opening / closing machine can stop the shutter curtain 50 at an arbitrary position in the opening / closing direction by restricting the rotation of the winding shaft 82 by the brake. That is, the opening / closing device determines the degree to which the shutter curtain 50 opens the opening 60 from the closed state in which the seat plate 52 of the shutter curtain 50 is positioned closest to the fully open state in which the seat plate 52 is positioned closest to the open side. Can be adjusted arbitrarily.

  The shutter curtain 50 has a mass that can move in the closing direction by its own weight when the brake of the opening / closing machine is released. Therefore, the switch can release the brake and move the shutter curtain 50 in the closing direction by its own weight, or can move the shutter curtain 50 in the closing direction by rotationally driving the winding shaft 82.

  The shutter curtain 50 and the sleeve door 70 of the present embodiment can function as a fire door that closes the opening 60 in an emergency such as a fire. The opening / closing body device 1-2 includes a control device that integrally controls the shutter curtain 50 and the sleeve door 70. The control device closes the opening 60 by the shutter curtain 50 and the sleeve door 70 in an emergency such as when smoke or heat is sensed. The automatic closing mechanism of the sleeve door 70 can be the same as the automatic closing mechanism of the first embodiment.

  The shutter curtain 50 is wound around the winding shaft 82 so that the first surface 50A, which is the surface forming the first space 61 in the closed state, is positioned on the outer peripheral side. In other words, in the shutter curtain 50, the first surface 50A faces the outer side in the radial direction of the winding shaft 82, and the second surface 50B, which is the surface that forms the second space 62 in the closed state, is the inner side in the radial direction of the winding shaft 82.

That is, it is preferable that the shape and arrangement of the display unit 54 make it easy for an evacuee or the like to visually recognize whether or not the shutter curtain 50 closes the opening 60. The display unit 54 emits light, so that the open / close state of the shutter curtain 50 can be visually understood even in the event of a power failure or darkness. The display unit 54 may be arranged not only on the first surface 50A but also on the second surface 50B.

  The display unit 54 may be provided from one end to the other end in the width direction on the first surface 50A, for example. In this way, it becomes easy to visually recognize the presence or absence of the shutter curtain 50. The display unit 54 may be provided so as to include at least the end region in the closing direction on the first surface 50A. In this way, it becomes easy to visually recognize whether or not the shutter curtain 50 closes the opening 60. Further, if the display unit 54 is provided so as to include the end region in the closing direction, when the shutter curtain 50 moves in the closing direction as indicated by an arrow Y3 in FIG. It will be easier to see if it has moved to a position.

  Here, since the shutter curtain 50 is stored in the storage unit 80 in the open state in which the opening 60 is opened, there is a possibility that the display unit 54 cannot store the light sufficiently. As shown in FIG. 6, the shutter curtain 50 is wound around the winding shaft 82 in the open state and stored in the storage space 83 of the storage unit 80. A seat plate 52 is positioned in the opening 81D that connects the storage space 83 and the indoor spaces 61 and 62 to block light, and light does not easily reach the storage space 83. For this reason, there is a possibility that the display unit 54 cannot sufficiently receive light in the open state.

  The opening / closing body device 1-2 of the present embodiment includes an illumination system 90. The illumination system 90 includes a photovoltaic device 91, an illumination device 92, and a power cable 93. The photovoltaic device 91 converts light energy into electric power and outputs it. The photovoltaic device 91 is disposed on the surface of the ceiling member 64 that faces the closing direction, that is, the lower surface. The photovoltaic device 91 is attached to the ceiling member 64 so that the light receiving portion 91A faces the closing direction. The photovoltaic power generation device 91 generates power with room light in the second space 62.

  The illuminating device 92 irradiates the display portion 54 on the outer peripheral surface of the shutter curtain 50 wound around the winding shaft 82. The illumination device 92 includes a plurality of light sources 94 (94A, 94B, 94C, 94D) such as LEDs. The light sources 94A, 94B, and 94C are disposed on the inner wall surfaces of the plate portions 81A, 81B, and 81C of the case 81, respectively. The light source 94D is disposed in the vicinity of the wall surface 67A of the case 81. Each light source 94 and the photovoltaic device 91 are connected by a power cable 93. Each light source 94 emits light by the electric power supplied from the photovoltaic power generation device 91 and irradiates the first surface 50A of the shutter curtain 50 wound around the winding shaft 82 with light. Each light source 94 may be a point light source or a linear light source extending in the width direction of the shutter curtain 50, for example.

  Here, since the display unit 54 is provided on the first surface 50A, the display unit 54 receives the light emitted from each light source 94. That is, each light source 94 irradiates the display unit 54 on the first surface 50 </ b> A of the shutter curtain 50. Therefore, according to the present embodiment, the display unit 54 can receive the light emitted from the illumination device 92 and store the light appropriately. Since the display unit 54 stores light in advance in the open state, the visibility of the display unit 54 when the shutter curtain 50 closes the opening 60 in an emergency or the like can be improved.

  Further, the display unit 54 of the present embodiment is provided with a display unit 54 in a region including the region of the end portion in the closing direction of the shutter curtain 50. Therefore, the display unit 54 is exposed to the outermost periphery of the wound shutter curtain 50 even when the shutter curtain 50 is fully opened in the opening direction. Therefore, according to the present embodiment, a wide area in the display unit 54, particularly an area on the end side in the closing direction, can receive the light emitted from the lighting device 92 and store it appropriately.

  In the display unit 54, even if there is a region that is not exposed at the outermost periphery in the fully opened state, the region can receive and store the light of the illumination device 92 when the shutter curtain 50 is extended from the storage unit 80. it can. When the shutter curtain 50 is extended, the area that has not received light until then can be illuminated and stored by the respective light sources 94. That is, the display unit 54 can store light until it is drawn out toward the first space 61 through the opening 81D, and can emit light when exposed to the first space 61.

  The light source 94 may be a surface light source. For example, a surface light source may be arranged on the inner wall surface and the wall surface 67A of each plate portion 81A, 81B, 81C to irradiate the display unit 54 of the shutter curtain 50. These surface light sources serve as light emitting surfaces facing the display unit 54 of the shutter curtain 50 stored in the storage unit 80.

  Although the shutter curtain 50 of the present embodiment is a slat connecting body in which a plurality of slats 51 are connected, it is not limited to this. For example, the shutter curtain 50 may be a sheet having flexibility, or may be another known shutter curtain.

  Moreover, the shutter curtain 50 is not limited to what has a function as a fire door. That is, this embodiment is not limited to a fire door, but is a shutter curtain that opens or closes the opening 60, and is generally applicable to a shutter curtain that is normally stored in the storage and closes the opening at any time.

[Modification of Second Embodiment]
A modification of the second embodiment will be described. In this modification, the display part is provided in the seat plate, and the point which irradiates indoor light to this display part and accumulates it is different from the said 2nd Embodiment.
