[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-285387 Summary of the Invention [Problem to be solved by the invention]

[0004] When curtains and curtain rails are stored in a conventional storage box, when looking at a wall with a window from the room side, the curtains and curtain rails are hidden from view, but the window is, emphasizing the presence of the window. However, when the storage box is attached to the wall as in the conventional technology, the storage box is also visible and its presence is emphasized, making it difficult to emphasize the presence of the window. Furthermore, the storage box bulging out from the interior creates a feeling of oppression. Therefore, there has been a demand for a room that feels spacious, even when a storage box is installed.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to be able to emphasize the presence of a window and make a room feel spacious. [Means for solving the problem]

[0006] The invention described in claim 1 relates to a room 11 structure including a wall 16 (front wall 16) formed to have a hollow interior, and a ceiling 13 (a ceiling portion provided at the highest position of the ceiling 13) provided continuously with the wall 16, as shown in, for example, FIGS. 1 to 8, The wall 16 is formed with openings 16a, 16b (first opening 16a, second opening 16b) penetrating the wall 16 in the thickness direction, The upper ends of the openings 16a and 16b are located above the height position of the ceiling 13, Window frames 21, 22 (first window frame 21, second window frame 22) are attached to the openings 16a, 16b, The window frames 21 and 22 are a frame portion (a rectangular frame portion consisting of a lower frame plate portion 23, a pair of first side frame plate portions 24a, and a first upper frame plate portion 25a) fixed to the inner peripheral edge portions of the openings 16a and 16b and constituting the openings 16a and 16b; and side storage sections 21a, 21b, 22a, 22b for storing a shielding material 62 (curtain 62) for shielding the openings 16a, 16b, The side storage sections 21a, 21b, 22a, 22b are located on the sides outside the frame section, and are arranged in the internal hollow section of the wall 16, and are open toward the openings 16a, 16b.

[0007] According to the invention recited in claim 1, the upper ends of the openings 16a, 16b, whose visibility is defined by the frame portions of the window frames 21, 22, are located above the height of the ceiling 13, so that the presence of the openings 16a, 16b as windows is emphasized compared to when the upper ends are located below the height of the ceiling 13, and people in the room 11 are more likely to look upward, making the room 11 seem larger to those in the room 11. Furthermore, the side storage sections 21a, 21b, 22a, 22b that store the shielding material 62 (curtain 62) are located to the sides outside the frame portions, are arranged in the hollow interior of the wall 16, and are open toward the openings 16a, 16b, so that the side storage sections 21a, 21b, 22a, 22b are less likely to be in the field of view of people in the room 11, and do not make people in the room 11 feel oppressive. Therefore, even if the side storage sections 21a, 21b, 22a, 22b for storing the shielding material 62 are provided, the openings 16a, 16b can emphasize their presence as windows and make the room 11 feel spacious to people in the room 11.

[0008] The invention described in claim 2 is, for example, as shown in Figures 2, 5, 7, and 8, in the room 11 structure described in claim 1, The window frames 21 and 22 further include upper storage sections 21c and 22c in which a hanging section 63 (curtain rail 63) for hanging the shielding material 62 is stored. The upper storage sections 21c and 22c are located above and outside the frame section, are arranged in the hollow interior of the wall 16, and are open toward the openings 16a and 16b.

[0009] According to the invention recited in claim 2, the upper storage sections 21c and 22c in which the hanging section 63 is stored are located above and outside the frame section, and are disposed in the hollow section inside the wall 16, and are open towards the openings 16a and 16b, so that the upper storage sections 21c and 22c are unlikely to be in the field of view of people in the room 11 and do not make people in the room 11 feel oppressive. Therefore, even if the upper storage sections 21c and 22c in which the hanging section 63 is stored are provided, the openings 16a and 16b can emphasize their presence as windows and make the room 11 feel larger to people in the room 11.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 2 and 5 to 7, in the room 11 structure described in claim 1, Groove-shaped slits 13a and 13b are formed in the ceiling 13, extending from the end of the ceiling 13 on the wall 16 side to the opposite end, The position of the openings 16a and 16b and the position of the slits 13a and 13b in the same direction as the width direction of the wall 16 of the room 11 are aligned.

[0011] According to the invention described in claim 3, the positions of the openings 16a, 16b, whose upper ends are located above the height of the ceiling 13, and the positions of the groove-shaped slits 13a, 13b, which extend from the end on the wall 16 side to the opposite end, are aligned, so that the openings 16a, 16b and the slits 13a, 13b appear as if they are continuous. This makes it possible to emphasize the presence of the openings 16a, 16b as windows and to make the room 11 appear larger to people in the room 11.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 2 and 5 to 7, in the room 11 structure described in claim 3, The slits 13a, 13b are formed as openings of lighting storage spaces 14, 15 for lighting fixtures 60 formed above the ceiling 13, and the lighting storage spaces 14, 15 are characterized in that the lighting fixtures 60 are stored therein.

[0013] According to the invention described in claim 4, slits 13a and 13b are formed as openings in lighting storage spaces 14 and 15 for lighting fixture 60 formed above ceiling 13, allowing light from lighting fixture 60 to pour into room 11 through slits 13a and 13b. As a result, light entering room 11 through openings 16a and 16b in wall 16 and light from lighting fixture 60 on ceiling 13 intersect within room 11, brightly illuminating room 11. Furthermore, openings 16a and 16b and slits 13a and 13b appear as if they are continuous, giving the impression that light entering through openings 16a and 16b reaches deep into room 11. Therefore, openings 16a and 16b can emphasize their presence as windows and make room 11 feel larger to people in room 11.

[0014] The invention described in claim 5 is, for example, as shown in Figs. 1 to 7, in the room 11 structure described in claim 3, The openings 16a and 16b are formed at intervals in the width direction of the wall 16, The slits 13a and 13b are formed in the ceiling 13 in the same number as the openings 16a and 16b, The plurality of openings 16a, 16b and the plurality of slits 13a, 13b are characterized in that each of the openings 16a, 16b and each of the slits 13a, 13b are paired and are arranged in the same position.

[0015] According to the invention of claim 5, the plurality of openings 16a, 16b and the plurality of slits 13a, 13b are arranged in pairs, with each opening 16a, 16b and each slit 13a, 13b being aligned with one another, so that a plurality of openings 16a, 16b and slits 13a, 13b arranged in pairs appear in room 11. Furthermore, the openings 16a, 16b and the slits 13a, 13b can be made to appear as if they are continuous, so that the openings 16a, 16b can emphasize their presence as windows and can make the room 11 appear larger to people in the room 11.

[0016] The invention described in claim 6 is, for example, as shown in Figures 2, 4, 5, and 7, in the room 11 structure described in claim 3, A storage recess 30 is formed between the end of the ceiling 13 on the wall 16 side and the slits 13a, 13b, and stores a downwardly deployable screen 64.

[0017] According to the invention recited in claim 6, a storage recess 30 storing a downwardly deployable screen 64 is formed between the end of ceiling 13 on the wall 16 side and slits 13a, 13b, so that screen 64 is less likely to be in the field of view of people in room 11, and people in room 11 do not feel oppressed. Therefore, even if screen 64 is provided in ceiling 13, openings 16a, 16b can emphasize their presence as windows and make room 11 feel larger to people in room 11. Meanwhile, by deploying screen 64 from storage recess 30, openings 16a, 16b can be temporarily covered, so people in room 11 can enjoy watching images projected onto screen 64 by projector 65.

[0018] The invention described in claim 7 is, for example, as shown in Figs. 2 and 3, in the room 11 structure described in any one of claims 1 to 6, The openings 16a and 16b are characterized in that they are formed long and vertically along the height direction of the wall 16.

[0019] According to the invention described in claim 7, the openings 16a and 16b are formed long and vertically along the height direction of the wall 16, so that a strip of light that is long in the height direction can be inserted into the room 11. This makes it easier for the light to reach the back of the room 11, so the openings 16a and 16b can be emphasized as windows. [Effects of the Invention]

[0020] According to the present invention, the presence of a window can be emphasized and the room can be made to feel spacious. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for carrying out the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions and orientations in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0023] In FIG. 1, the reference numeral 1 denotes a multi-story building. This building 1 is a residence and church, and is provided with a chapel 11 (i.e., room 11) on a predetermined floor. The building 1 in this embodiment is, for example, a steel-framed building, but is not limited to this and may be a building of other structure, for example, wooden. In other words, there are no particular limitations on the construction method used to construct the building 1. Furthermore, although the use of the building 1 is described as a residence and church, it is not limited to this and may be a building for only a residence, only a church, or for other purposes.

[0024] Stairs 2 and elevators 3 are located in the west and northwest sections of building 1, which are used to travel between floors. At specific floors within this transitional space, there is a staircase landing / elevator hall 4. From the staircase landing / elevator hall 4, one passes through a doored entrance and moves south to find a vestibule 5. In vestibule 5, there are a first toilet 6, a second toilet 7, and a third toilet 8, which is a multi-purpose toilet. From the reception space 5, if you go through a doorway and move to the east, you will find the chapel 11. Furthermore, to the south of the chapel 11, the kitchen room 9 and the storage room 10 are located side by side.

[0025] As shown in Figure 4, the walls of building 1 including chapel 11 comprise steel columns 50, exterior wall materials 51 attached to the outdoor side of steel columns 50, interior wall materials 52 arranged on the indoor side of steel columns 50, and insulation material 53 filled in the space (hollow portion) between exterior wall materials 51 and interior wall materials 52. Although not shown, a support frame made of lightweight steel assembled to steel columns 50 is placed in the hollow space between the exterior wall material 51 and the interior wall material 52, and the exterior wall material 51 and the interior wall material 52 are fixed and supported not only by the steel columns 50 but also by the support frame as appropriate. The thickest part of the wall of such a building 1 is necessarily thicker than the cross section of the steel columns 50, and the dimension from the surface of the exterior wall material 51 to the surface of the interior wall material 52 is set to at least 350 mm.

[0026] The chapel 11 is a room that is roughly rectangular in plan view and is longer in the north-south direction than in the east-west direction, and at the northern end is an altar 12 whose floor is set higher than the prayer space, as shown in Figure 2 etc. Two steps are provided between the prayer space and the altar 12. In other words, the floor of the chapel 11 is set to have different heights between the prayer space and the altar 12. However, this is not limited to this, and the entire floor may be flat. In short, the floor of the chapel 11 is at different heights on the prayer space side and the altar 12 side, so the space of the chapel 11 itself is divided into areas.

[0027] The ceiling 13 of the chapel 11 is a so-called coved ceiling, formed with multiple steps from the top of the west wall and the top of the east wall toward the center, as shown in Figure 2. However, it may also be a flat ceiling without multiple steps. In this embodiment, two slits 13a and 13b extending in the north-south direction are formed in the ceiling portion provided at the highest position of the ceiling 13, which is a raised ceiling. As shown in Figures 5 and 6, the slit 13a located on the west side (hereinafter referred to as the first slit 13a) and the slit 13b located on the east side (hereinafter referred to as the second slit 13b) are formed as openings of lighting storage spaces 14, 15 for lighting fixtures 60 formed above the ceiling. The upper ends of the first slit 13a and the second slit 13b are closed by lighting covers 14a, 15a made of, for example, polycarbonate plates.

[0028] More specifically, long, hollow lighting storage spaces 14, 15 extending north-south are formed in the ceiling space above the highest part of the ceiling 13 in the chapel 11. These lighting storage spaces 14, 15 are formed by assembling the surface materials that make up the ceiling 13 into a box shape. The lighting storage space 14 located on the west side (hereinafter referred to as the first lighting storage space 14) and the lighting storage space 15 located on the east side (hereinafter referred to as the second lighting storage space 15) are open toward the inside of the room, i.e., downward, and these openings function as the above-mentioned first slit 13a and second slit 13b. Furthermore, the lighting covers 14a and 15a are respectively installed between the left and right side edges of the openings in the first lighting storage space 14 and the second lighting storage space 15, thereby closing the openings. Therefore, the lighting covers 14a and 15a are positioned higher than the highest part of the ceiling 13. In other words, the ceiling 13 in the chapel 11 has recessed grooves where the first slits 13a and the second slits 13b are formed, allowing light to pour in from above the first slits 13a and the second slits 13b.

[0029] Furthermore, multiple pins 14b, 15b stand at intervals in the north-south direction on the left and right side edges of the openings in the first lighting storage space 14 and the second lighting storage space 15. The lighting covers 14a, 15a can be positioned appropriately by aligning the pins 14b, 15b with multiple holes (not shown) formed along the left and right side edges of the lighting covers 14a, 15a. The lighting covers 14a and 15a are connected to the side walls of the first lighting storage space 14 and the second lighting storage space 15 by chains 14c and 15c, respectively, to prevent them from falling off in the unlikely event of an accident.

[0030] Additionally, multiple downlights 61 are installed in the highest part of the ceiling 13 in the chapel 11. In particular, multiple downlights 61 are clustered together in the part of the ceiling 13 located directly above the center of the altar 12, making it easier to perform religious ceremonies.

[0031] The walls of the chapel 11 have exposed columns in some areas. However, this is not limiting, and the walls of the chapel 11 may be flat walls without exposed columns. The east wall has an entrance 11a for accessing the landing of an external staircase (not shown). A cantilevered balcony 11b is provided on the outdoor side of the east wall, and a French window 11c for accessing the cantilevered balcony 11b and a window 11d for use as an emergency entrance are also provided on the east wall.

[0032] The wall located behind the altar 12, i.e., the front wall 16 that can be seen from the front as one enters the chapel 11, has a cross 17 hanging in the center, and on either side of it are a first vertical opening 16a and a second opening 16b, as shown in Figures 2 and 3.

[0033] An interior finishing material 54 is attached to the surface of the interior wall material 52 in the front wall 16. The interior finishing material 54 in this embodiment includes tiles and a base surface material to which the tiles are attached, and the tiles and base surface material may be formed into panels in advance. The surfaces of the interior wall materials 52 on all walls of the building 1 except for the front wall 16 are also finished with an interior finish, but as shown in Figure 2, they are not tiled and have a different design from the front wall 13. This gives the front wall 13 a relatively more solid image.

[0034] The first opening 16a and the second opening 16b penetrate the front wall 16 in the thickness direction. Furthermore, the lower ends of the first opening 16a and the second opening 16b are set at a height close to the height of the floor of the altar 12, as shown in Figures 2 and 3, and the upper ends are located at a height higher than the highest part of the ceiling 13 in the chapel 11, as shown in Figures 2, 3, 5, and 6. 5 (FIG. 8), the dashed-dotted line A indicates the height position of the ceiling portion that is located at the highest position of the ceiling 13. The dashed-dotted line B indicates the height position of the upper ends of the first opening 16a and the second opening 16b, or the upper ends of the first window sash 18 and the second window sash 19. The positions of the first opening 16a and the first slit 13a in the east-west direction of the chapel 11 are aligned. In other words, the first opening 16a and the first slit 13a are arranged in the same position in the east-west direction of the chapel 11. Similarly, the positions of the second opening 16b and the second slit 13b in the east-west direction of the chapel 11 are aligned. In other words, the second opening 16b and the second slit 13b are arranged in the same position in the east-west direction of the chapel 11.

[0035] Window sashes 18, 19 are fitted into the outdoor-side edges of the first opening 16a and the second opening 16, respectively. As described above, the walls of the building 1 are formed to a certain degree of thickness. Therefore, when the window sashes 18, 19 are fitted into the outdoor-side edges, the front wall 16 becomes a recessed groove where the first opening 16a and the second opening 16b are formed, allowing light to pour in from the outdoors.

[0036] More specifically, a first window sash 18 that closes the first opening 16a is fitted into the outdoor edge of the first opening 16a. The first window sash 18 is a fixed-type window sash with two sashes, one above the other, but is not limited to this and may be configured to be openable and closable. As described above, the upper end of first opening 16a is located at a height position higher than the highest ceiling portion of ceiling 13. Therefore, the upper end of first window sash 18 fitted into first opening 16a is also located at a height position higher than the highest ceiling portion of ceiling 13, as shown in Figures 2, 3, 5, and 6.

[0037] Similarly, a second window sash 19 that closes the second opening 16b is fitted into the outdoor edge of the second opening 16b. The second window sash 19 is a fixed type window sash with two sashes, one above the other, but is not limited to this and may be configured to be openable and closable. As described above, the upper end of second opening 16b is located at a height position higher than the ceiling portion located at the highest position on ceiling 13. Therefore, the upper end of second window sash 19 fitted into second opening 16b is also located at a height position higher than the ceiling portion located at the highest position on ceiling 13, as shown in Figures 2, 3, 5, and 6.

[0038] Furthermore, the upper end of the first window sash 18 and the lighting cover 14a provided in the first slit 13a of the ceiling 13 are set to be at approximately the same height. Similarly, the upper end of the second window sash 19 and the lighting cover 15a provided in the second slit 13b of the ceiling 13 are set to be approximately the same height. In other words, the grooves formed by the first opening 16a and the second opening 16b in the front wall 16 and the grooves formed by the first slits 13a and the second slits 13b in the ceiling 13 are arranged in a continuous manner. Therefore, sunlight entering the room through the first window sash 18 and the second window sash 19 fitted into the first opening 16a and the second opening 16b, respectively, intersects with the light from the lighting fixtures 60 pouring into the room through the lighting covers 14a and 15a. This allows light to extend in the north-south direction from both sides of the cross 17 in the chapel 11, giving it a majestic image.

[0039] Furthermore, a first window frame 21 and a second window frame 22 are provided on the edges of the first opening 16a and the second opening 16b, respectively, inside the first window sash 18 and the second window sash 19.

[0040] As shown in Figures 4, 5, 7, and 8, the first window frame 21 is configured to be able to store a shielding material 62 for shielding the first window sash 18, such as a cloth curtain, blind curtain, roller screen, etc., and a hanging portion 63 for hanging this shielding material 62. Specifically, the first window frame 21 includes a first storage section 21a and a second storage section 21b that are disposed on both the left and right ends of the first window frame 21 and store the shielding material 62, and a third storage section 21c that is disposed on the upper end of the first window frame 21 and stores the hanging section 63. The third storage section 21c is located above the first storage section 21a and the second storage section 21b, and is provided across the space between the first storage section 21a and the second storage section 21b. Furthermore, since the shielding material 62 is hung from the hanging portion 63 stored in the third storage section 21c, the internal spaces of the third storage section 21c, the first storage section 21a and the second storage section 21b are spatially continuous without any obstructions.

[0041] Similar to the first window frame 21, the second window frame 22 is also configured to be able to store the shielding material 62 and the hanging portion 63, and is provided with a first storage section 22a and a second storage section 22b that are arranged on both the left and right ends of the second window frame 22 and store the shielding material 62, and a third storage section 22c that is arranged on the upper end of the second window frame 22 and stores the hanging portion 63. The functions of these first storage section 22a, second storage section 22b, and third storage section 22c are similar to those of the storage sections 21a, 21b, and 21c in the first window frame 21.

[0042] In this embodiment, a vertical blind curtain (hereinafter referred to as a curtain 62) is used as the shielding material 62. A curtain rail is used as the hanging portion 63. In particular, the curtain rail of this embodiment is an electric type that electrically operates the opening and closing of the curtain 62, which is a vertical blind curtain.

[0043] Since the first window frame 21 and the second window frame 22 have the same configuration, only the first window frame 21 will be described in detail, and the description of the second window frame 22 will be omitted. In this embodiment, the first window frame 21 and the second window frame 22 are made of wood, but this is not limiting and other materials such as resin or metal may also be used. The components of the first window frame 21 and the second window frame 22 are joined together using fixing materials such as screws and nails, and adhesives as appropriate.

[0044] To explain the first window frame 21 in more detail, the first window frame 21 is provided at the lower edge of the first opening 16a and has a lower frame plate portion 23 with which the lower end of the first window sash 18 contacts. The lower frame plate portion 23 is formed in a generally cross shape in plan view, and the lower end portion of the first window sash 18 is in contact with the portion of the lower frame plate portion 23 that extends to the north side (outdoors). The first window frame 21 has a planar shape that matches the shape of this lower frame plate portion 23. In other words, the first window frame 21 is formed in a cross shape in a plan view.

[0045] A plurality of side frame plates 24a, 24b, 24c, 24d, and 24e are joined to the outer peripheral edge of the cross-shaped lower frame plate 23, excluding the outdoor-side edge that contacts the first window sash 18 and the indoor-side edge located directly opposite the outdoor-side edge. The ends of adjacent side frame plates 24a, 24b, 24c, 24d, and 24e are joined together.

[0046] Of the multiple side frame plate portions, the first side frame plate portion 24a is a pair of parallel frame plates that, in plan view, are perpendicular to the indoor side edge of the lower frame plate portion 23. In other words, the pair of first side frame plate portions 24a form the left and right side surfaces of the portion of the first window frame 21 that is formed in a cross shape in plan view and that protrudes to the south. A first upper frame plate portion 25a is provided at the upper edge of the first opening 16a and bridges between the upper ends of the pair of first side frame plate portions 24a. The indoor-side edge of the first window frame 21 is formed into a rectangular frame shape by the part of the lower frame plate 23 that protrudes to the south, the pair of first side frame plate portions 24a, and the first upper frame plate portion 25a. In other words, when the first opening 16a is viewed from the indoor side, the rectangular frame portion is recognized as part of the "window frame." More specifically, the rectangular frame portion constitutes both the visible portion and part of the interior of the first window frame 21.

[0047] Of the multiple side frame plate portions, the second side frame plate portions 24b are a pair of frame plates that are perpendicular to the pair of first side frame plate portions 24a in a plan view. Furthermore, the pair of second side frame plate portions 24b are arranged in a straight line in a plan view. That is, the pair of second side frame plate portions 24b form the indoor side surfaces of the portions of the first window frame 21 that are cross-shaped in a plan view and protrude to the east and west. The pair of second side frame plate portions 24b are disposed within the hollow portion of the front wall 16 and are provided along the rear surface of the inner wall material 52, so as to be difficult to see from inside the room. The pair of second side frame plate portions 24b constitute the first storage section 21a and the second storage section 21b in which the curtain 62 is stored.

[0048] Of the multiple side frame plate portions, the third side frame plate portions 24c are a pair of parallel frame plates that are perpendicular to the pair of second side frame plate portions 24b in plan view. That is, the pair of third side frame plate portions 24c form the protruding end faces of the portions of the first window frame 21 that are formed in a cross shape in plan view and that protrude to the east and west. The pair of third side frame plate portions 24c are disposed within the hollow portion of the front wall 16, spanning between the exterior wall material 51 and the interior wall material 52, and are therefore difficult to see from inside the room. The pair of third side frame plate portions 24c constitute the first storage section 21a and the second storage section 21b in which the curtain 62 is stored, and also constitute the third storage section 21c in which the curtain rail 63 is stored.

[0049] Among the multiple side frame plate portions, the fourth side frame plate portions 24d are a pair of frame plates that are perpendicular to the pair of third side frame plate portions 24c in a plan view. Furthermore, the pair of fourth side frame plate portions 24d are arranged in a straight line in a plan view. That is, the pair of fourth side frame plate portions 24d constitute the outdoor side surfaces of the portions of the first window frame 21 that are cross-shaped in a plan view and protrude to the east and west. The pair of fourth side frame plate portions 24d are disposed within the hollow portion of the front wall 16 and are provided along the rear surface of the exterior wall material 51, so as to be difficult to see from inside the room. The pair of fourth side frame plate portions 24d constitute the first storage section 21a and the second storage section 21b in which the curtain 62 is stored.

[0050] Of the multiple side frame plate portions, the fifth side frame plate portion 24e is a pair of parallel frame plates that are perpendicular to the outdoor-side edge of the lower frame plate portion 23 in a plan view. The pair of fifth side frame plate portions 24e also form a pair of frame plates that are perpendicular to the pair of fourth side frame plate portions 24d in a plan view. In other words, the pair of fifth side frame plate portions 24e form the left and right side surfaces of the portion of the first window frame 21 that is formed in a cross shape in a plan view and that protrudes to the north. A second upper frame plate portion 25b is provided at the upper edge of the first opening 16a and is bridged between the upper ends of the pair of fifth side frame plate portions 24e. This second upper frame plate portion 25b is disposed at a distance from the first upper frame plate portion 25a in the north-south direction and is disposed at the same height as the first upper frame plate portion 25a. The outdoor edge of the first window frame 21 is formed into a rectangular frame shape by the north-protruding portion of the lower frame plate 23, the pair of fifth side frame plate portions 24e, and the second upper frame plate portion 25b. The first window sash 18 is installed adjacent to the extension of this rectangular frame portion. In other words, when viewing the first opening 16a from the indoor side, the rectangular frame portion is recognized as part of the "window frame." More specifically, the rectangular frame portion constitutes part of the first window frame 21. In other words, there is a gap between the first side frame plate portion 24a and the fifth side frame plate portion 24e that allows the first storage section 21a and the second storage section 21b to be formed. Therefore, the first side frame plate portion 24a and the fifth side frame plate portion 24e constitute part of the first window frame 21.

[0051] Furthermore, among the multiple side frame plate portions, the third side frame plate portion 24c is formed longer than the other side frame plate portions, and its upper end portion protrudes upward further than the first upper frame plate portion 25a and the second upper frame plate portion 25b. A first upper end plate portion 26a that constitutes the upper end surface of the entire first window frame 21 is provided between the upper end surfaces of the pair of third side frame plate portions 24c. Furthermore, a second upper end plate portion 26b, which forms the indoor side surface of the portion of the first window frame 21 located above the first upper frame plate portion 25a, is provided spanning between the indoor side surfaces at the upper ends of the pair of third side frame plate portions 24c. Furthermore, a third upper end plate portion 26c is provided between the outdoor side surfaces of the upper ends of the pair of third side frame plate portions 24c, and forms the outdoor side surface of the portion of the first window frame 21 that is located above the second upper frame plate portion 25b. As a result, a third storage section 21c for storing the curtain rail 63 is formed above the first upper frame plate section 25a and the second upper frame plate section 25b.

[0052] The first window frame 21 configured as described above is placed in the hollow space between the exterior wall material 51 and the interior wall material 52, and is screwed to a support frame (not shown) made of lightweight steel material assembled to a steel column 50.

[0053] The curtain rail 63 is attached to the underside of the first upper end plate portion 26a. The curtain rail 63 is formed long along the length of the first upper end plate portion 26a, and is provided from one end to the other end in the length direction of the first upper end plate portion 26a. The curtain 62 hung from such a curtain rail 63 can be spread from one end to the other end in the length direction of the curtain rail 63. That is, when the curtain 62 is to cover the first window sash 18, it is spread from one end to the other end in the length direction of the curtain rail 63. On the other hand, when the first window sash 18 is not to be covered, the curtain 62 is arranged in a state where it is gathered to one end in the length direction of the curtain rail 63. In this case, the curtain 62 is stored in either the first storage section 21a or the second storage section 21b in the first window frame 21. Note that, because the curtain rail 63 in this embodiment is an electrically operated type, when the curtain 62 is not to cover the first window sash 18, it is assumed that the curtain 62 is always stored in the first storage section 21a.

[0054] The length of the curtain 62 is set to be approximately equal to the length from the curtain rail 63 to the vicinity of the lower frame plate portion 23. Because the height position of the curtain rail 63 is higher than the height position of the ceiling 13, the upper end of the curtain 62 is also positioned higher than the height position of the ceiling 13. In other words, since not only the curtain rail 63 but also the upper end of the curtain 62 is stored in the third storage portion 21c of the first window frame 21, when the first window sash 18 is shielded by the curtain 62, it is possible to prevent light from leaking through the gap between the curtain 62 and the curtain rail 63. In other words, the upper end of the first window sash 18 can be reliably shielded by the upper end of the curtain 62.

[0055] In the present embodiment, as shown in Figures 2, 4, 5, 7, etc., the ceiling 13 is formed adjacent to the front wall 16 with a storage recess 30 for storing the electric screen 64. The storage recess 30 is formed in the shape of a long, narrow slit, as long as it can store the electric screen 64 and allow the screen main body 64a to move up and down. That is, the storage recess 30 is formed in the ceiling 13 near the upper end of the front wall 16, in the shape of a long slit that runs along the width direction of the front wall 16. This storage recess 30 has a ceiling surface and four side walls and is open downward, so that the screen main body 64a of the electric screen 64 attached to the ceiling surface of the storage recess 30 moves in and out through the opening when it is electrically moved up and down.

[0056] 7, the screen body 64a of the electric screen 64 can be deployed up to the vicinity of the lower ends of the first opening 16a and the second opening 16b, and can cover most of the front wall 16. In other words, most of the first opening 16a and the second opening 16b are also covered by the screen body 64a. An image is projected from a projector 65 onto a screen body 64a of the electric screen 64. When using the electric screen 64, it is desirable to close the first window sash 18 and the second window sash 19 with curtains 62 so that light from outside does not affect the projected image. The projector 65 shown in FIG. 7 is placed on a stand when in use.

[0057] According to this embodiment, the following excellent effects are achieved. That is, the upper ends of the first opening 16a and the second opening 16b, which are formed by the frame portions (rectangular frame portions) of the first window frame 21 and the second window frame 22, are located above the height of the ceiling 13, so that the presence of the first opening 16a and the second opening 16b as windows is emphasized compared to when the upper ends are located below the height of the ceiling 13, and people in the room 11 are more likely to look upward, making the room 11 feel larger. Furthermore, the first storage sections 21a, 22a and the second storage sections 21b, 22b, which store the curtain 62, are located to the side outside the frame portions, are arranged in the internal hollow portion of the front wall 16, and are open toward the first opening 16a and the second opening 16b. Therefore, the first storage sections 21a, 22a and the second storage sections 21b, 22b are less likely to be in the field of view of people in the room 11, and do not make people in the room 11 feel oppressive. Therefore, even if the first storage section 21a, 22a and the second storage section 21b, 22b in which the shielding material 62 is stored are provided, the first opening 16a and the second opening 16b can emphasize their presence as windows and make the room 11 feel larger to people in the room 11.

[0058] Furthermore, third storage sections 21c, 22c in which curtain rail 63 is stored are located above and outside the frame section, are disposed in the hollow interior of front wall 16, and are open toward first opening 16a and second opening 16b, so third storage sections 21c, 22c are less likely to be in the field of view of people in room 11 and do not make people in room 11 feel oppressive. Therefore, even if third storage sections 21c, 22c in which curtain rail 63 is stored are provided, first opening 16a and second opening 16b can emphasize their presence as windows and can make room 11 feel larger to people in room 11.

[0059] Furthermore, the positions of the first opening 16a and the second opening 16b, whose upper ends are located above the height of the ceiling 13, and the positions of the groove-shaped first slits 13a and second slits 13b that extend from the end on the front wall 16 side to the opposite end are aligned, so that the first opening 16a and the second opening 16b and the first slits 13a and the second slits 13b appear to be continuous with each other. This makes it possible to emphasize the presence of the first opening 16a and the second opening 16b as windows and to make the room 11 appear larger to people in the room 11.

[0060] Furthermore, because the first slits 13a and the second slits 13b are formed as openings for the lighting storage spaces 14, 15 for the lighting fixtures 60 formed above the ceiling 13, light from the lighting fixtures 60 can be allowed to pour into the room 11 through the first slits 13a and the second slits 13b. As a result, the light entering the room 11 from the first openings 16a and the second openings 16b in the front wall 16 and the light from the lighting fixtures 60 on the ceiling 13 intersect within the room 11, thereby brightly illuminating the room 11. Furthermore, because the first openings 16a and the second openings 16b and the first slits 13a and the second slits 13b can be made to appear as if they are continuous, the impression that the light entering through the first openings 16a and the second openings 16b reaches deep into the room 11 can be created. Therefore, the first openings 16a and the second openings 16b can emphasize their presence as windows and make the room 11 feel larger to people in the room 11.

[0061] Furthermore, the first opening 16a and the second opening 16b, and the first slit 13a and the second slit 13b are each paired with each other and are positioned in the same order, so that a plurality of pairs of first opening 16a and first slit 13a and second opening 16b and second slit 13b appear in room 11. These pairs of opening and slit can be made to appear as if they have continuity, so that first opening 16a and second opening 16b can emphasize their presence as windows and can make room 11 appear larger to people in room 11.

[0062] Furthermore, a storage recess 30 that stores a downwardly deployable screen 64 is formed between the end of the ceiling 13 on the front wall 16 side and the first slit 13a and the second slit 13b, so that the screen 64 is less likely to be in the field of view of people in the room 11 and does not make people in the room 11 feel oppressive. Therefore, even if the screen 64 is provided on the ceiling 13, the first opening 16a and the second opening 16b can emphasize their presence as windows and make people in the room 11 feel that the room 11 is spacious. Meanwhile, by deploying the screen 64 from the storage recess 30, the first opening 16a and the second opening 16b can be temporarily covered, so that people can enjoy watching the images projected onto the screen 64 by the projector 65.

[0063] Furthermore, the first opening 16a and the second opening 16b are formed long and vertically along the height direction of the wall 16, so that a strip of light that is long in the height direction can be inserted into the room 11. This makes it easier for the light to reach the back of the room 11, so the first opening 16a and the second opening 16b can be emphasized as windows.

[0064] Furthermore, in recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and in the construction industry as well, efforts are being made to build buildings using wood, which reduces carbon dioxide emissions. Because wood is used as the material for the first window frame 21 and the second window frame 22 in this embodiment, it is possible to contribute to the realization of a carbon-neutral society by promoting carbon neutrality and the achievement of the SDGs.
