Description

The present invention relates to housing.

Patent Document 1 discloses a home with an upper and lower floor, with an intermediate floor (skip floor) on the upper floor. In the home described in Patent Document 1, an upper floor living space such as a bedroom is formed above the intermediate floor, and a storage space is formed below the intermediate floor. In this case, both the upper floor living space and the storage space are low-ceilinged spaces. In addition, windows are provided on the exterior walls of the upper floor living space and the storage space. This allows outside light to enter the upper floor living space and storage space through the respective windows.

Japanese Patent Application Laid-Open No. 2008-144391

In the house described in Patent Document 1, the windows in the upper floor living spaces and storage spaces are both formed to match the ceiling height of these low-ceiling spaces. As a result, the vertical dimensions of these windows are significantly smaller than the other windows on the upper floors. In this case, when the house is viewed from outside, these windows appear out of balance with the other windows, which could mar the appearance of the house.

It is also possible to avoid spoiling the appearance of the house by not installing windows in the living spaces and storage spaces on the upper floors, but this is undesirable as it would prevent natural light from entering these spaces.

The present invention was made in consideration of the above circumstances, and its primary purpose is to allow light to enter both the lower and upper spaces separated by the skip floor section in a home equipped with a skip floor section, while minimizing damage to the exterior appearance.

To solve the above problem, the first invention of the house is a house equipped with a skip floor section set at a height different from the normal floor height, and a lower space section and an upper space section separated vertically by the skip floor section, the lower space section and the upper space section being adjacent to the outdoors across an exterior wall section, and the exterior wall section being provided with a light-transmitting window section that extends vertically across the skip floor section and allows light to enter the lower space section and the upper space section, respectively.

According to the first invention, because the light-receiving window section extends across the skip floor section both vertically and horizontally, the size of the light-receiving window section is not limited by the skip floor section. This ensures a balance between the light-receiving window section and other window sections. Furthermore, because the light-receiving window section extends across the skip floor section both vertically, it is possible to admit light into both the lower and upper spaces. This makes it possible for a home equipped with a skip floor section to admit external light into both the lower and upper spaces while minimizing damage to the exterior appearance.

The second invention is a house according to the first invention, characterized in that the skip floor section is composed of a ceiling surface material that forms the ceiling surface of the lower space section and a floor surface material that forms the floor surface of the upper space section, and is provided with a cover member that is provided between the light-receiving window section and the skip floor section and that conceals the space between the floor surface material and the ceiling surface material from the light-receiving window section side.

In the configuration of the first invention described above, in which the light-receiving window section is installed across the skip floor section from above and below, it is anticipated that the skip floor section will be visible through the light-receiving window section from the outside. Because the skip floor section is composed of the ceiling surface material of the lower space section and the floor surface material of the upper space section, in this case, there is a risk that components such as base materials arranged between the floor surface material and the ceiling surface material will also be visible from the outside. This could result in significant damage to the appearance of the house due to these normally invisible components becoming visible.

In light of this, the second invention provides a cover member between the light-receiving window and the skip floor section, which conceals the gap between the floor surface material and the ceiling surface material in the skip floor section from the light-receiving window side. This makes it impossible to see the gap between the floor surface material and the ceiling surface material from the outside through the light-receiving window, thereby avoiding any significant impairment to the exterior appearance of the house.

The third invention is a house according to the second invention, characterized in that the exterior wall has a window opening in which the light-receiving window is provided, the light-receiving window is positioned closer to the exterior of the window opening, and the light-receiving window and the skip floor are spaced apart, and the cover member has a covering portion that conceals the space between the ceiling surface material and the floor surface material, and an extension portion that extends from the covering portion toward the light-receiving window.

Normally, the light-transmitting window is positioned closer to the exterior of the window opening. Therefore, in a configuration in which the light-transmitting window spans the skip floor section vertically, the light-transmitting window and the skip floor section are spaced apart. This raises concerns that objects in the upper space could fall into the lower space through the gap between the light-transmitting window and the skip floor section. Therefore, according to the third invention, the cover member has a covering section that conceals the space between the ceiling surface material and the floor surface material, and an extension section that extends from the covering section toward the light-transmitting window section. In this case, the extension section covers the gap between the light-transmitting window section and the skip floor section. This prevents objects in the upper space from falling into the lower space.

The fourth invention is a house according to the third invention, characterized in that the extension extends from the upper end of the cover.

In the configuration of the third invention, in which an extension is provided between the light-receiving window and the skip floor, there is a concern that the extension will block the external light that enters through the light-receiving window, limiting the amount of light entering the lower space below the extension. In contrast, in the fourth invention, the extension extends from the upper end of the cover. This prevents the extension from limiting the amount of light entering the lower space. Therefore, light can be more effectively let into the lower space.

The fifth invention is a house according to the fourth invention, characterized in that the floor material has a floor finishing surface material that forms the floor surface of the upper space, and a portion of the floor finishing surface material is placed on the upper surface of the extension, or another floor material adjacent to the floor finishing surface material is placed on the upper surface of the extension.

According to the fifth aspect of the invention, the extension is covered from above by a portion of the floor finishing surface material (or another adjacent floor finishing surface material), thereby preventing the extension from spoiling the appearance of the upper space.

A sixth invention is a house according to the fifth invention, characterized in that the cover member has a rising portion that rises from the end of the extension portion on the light-receiving window side, and the rising portion covers and conceals a part of the floor finishing surface material or another floor finishing surface material placed on the upper surface of the extension portion from the light-receiving window side.

According to the sixth aspect of the invention, even if a floor finishing surface material is placed on the upper surface of the extension portion, the rising portion can obscure the floor finishing surface material from the light-receiving window side. This makes it possible to prevent the floor finishing surface material from being seen through the light-receiving window from the outside, more reliably avoiding damage to the exterior appearance of the house.

The seventh invention is a house according to any one of the second to sixth inventions, characterized in that the exterior wall has a window opening in which the light-receiving window is provided, a window frame is arranged along the periphery of the window opening, and the light-receiving window is arranged on the outdoor side of the window frame, and the cover member has a covering portion that is arranged in the middle of the window opening in the indoor/outdoor direction and conceals the space between the ceiling surface material and the floor surface material, and a fixing portion that extends from the side end of the covering portion toward the opposite side to the light-receiving window and is fixed to the window frame.

According to the seventh aspect of the invention, the fixing portion extends from the side end of the cover portion to the side opposite the light-receiving window. This makes it possible to make the fixing portion invisible from the outdoors through the light-receiving window, more reliably preventing the appearance of the house from being marred.

The eighth invention of the present invention is a house according to any one of the second to seventh inventions, characterized in that the floor surface material comprises a subfloor surface material and a floor finish surface material that is layered on top of the subfloor surface material and forms the floor surface of the upper space, and the cover member has a mounting portion placed on the upper surface of the subfloor surface material, and the mounting portion is arranged in a sandwiched state between the subfloor surface material and the floor finish surface material.

According to the eighth aspect of the present invention, the cover member has a mounting portion. The mounting portion is placed on the upper surface of the subfloor surface material. In this case, the height position of the cover member is determined by the mounting portion. This makes it easy to align the cover member when fixing it to the skip floor. The mounting portion is also positioned between the subfloor surface material and the floor finishing surface material. As a result, the mounting portion is covered from above by the floor finishing surface material, preventing the mounting portion from spoiling the appearance of the upper space.

The ninth invention is a house according to any one of the second to eighth inventions, characterized in that the surface of the cover member facing the light-receiving window is colored a dark color.

If a cover member is provided between the light-receiving window and the skip floor, there is a concern that the cover member may be visible through the light-receiving window from the outside. According to the ninth invention, the surface of the cover member facing the light-receiving window is colored a dark color. This prevents the cover member from being noticeable through the light-receiving window, more reliably preventing the appearance of the house from being marred.

An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the house is embodied as a two-story modular house. A modular house is constructed by combining multiple building units. Figure 1 is a cross-sectional view showing a portion of the house.

As shown in FIG. 1, the house 10 has a first floor portion 11, a second floor portion 12, and a roof portion 13 provided above the second floor portion 12. A first floor space 15 is provided in the first floor portion 11, and a second floor space 16 is provided in the second floor portion 12. The first floor space 15 is, for example, a hallway, and the second floor portion 12 is, for example, a living room. The roof portion 13 is a gable roof.

Floor section 17 of first floor space 15 and floor section 18 of second floor space 16 are both floor sections set at the normal height for each floor. In other words, these floor sections 17, 18 are not so-called skip floor sections.

The house 10 has an open-ceiling space 19 spanning the first floor 11 and the second floor 12. The open-ceiling space 19 serves as, for example, a living room. The open-ceiling space 19 has an open-ceiling opening 24 formed at the boundary between the first floor 11 and the second floor 12, and opens from the first floor 11 to the second floor 12 through the open-ceiling opening 24. The open-ceiling space 19 is adjacent to the first floor space 15 on the first floor 11, and is adjacent to the second floor space 16 on the second floor 12. The floor 21 of the open-ceiling space 19 is set at the same height as the floor 17 of the first floor space 15.

A skip floor section 26 is provided above the atrium space 19. The skip floor section 26 is set at an intermediate height between the floor section 18 and the ceiling section 23 in the second-floor space 16. In other words, the skip floor section 26 is provided at a height different from the normal floor height in the second-floor section 12.

A storage space 25 is provided above the skip floor 26 on the second floor 12. The storage space 25 is separated from the open-ceiling space 19 by the skip floor 26. This makes the storage space 25 a low-ceiling space. Items can be stored in the storage space 25. The storage space 25 and the open-ceiling space 19 are adjacent to the outdoors, separated by the exterior wall 32. The open-ceiling space 19 corresponds to the lower space, and the storage space 25 corresponds to the upper space.

The storage space 25 is adjacent to the second floor space 16. An opening 27 that opens to the second floor space 16 is formed in the storage space 25. The opening 27 faces the exterior wall portion 32 across the storage space 25. Access to the storage space 25 from the second floor space 16 is possible through this opening 27. Although not shown, the second floor portion 12 is provided with a ladder or staircase for ascending and descending between the second floor space 16 and the storage space 25.

A waist wall portion 28 is provided below the opening 27. The waist wall portion 28 is provided across the skip floor portion 26 and the floor portion 18 of the second-floor space 16. The waist wall portion 28 faces the exterior wall portion 32 across the atrium space 19.

As shown in FIG. 2, the second floor portion 12 is provided with a second floor living room 33 adjacent to the storage space 25 and the atrium space 19. The second floor living room 33 is adjacent to the outdoors via the exterior wall portion 32. The second floor portion 12 of the exterior wall portion 32 is provided with a light-transmitting window portion 34 that allows light to enter the second floor living room 33. The second floor portion 12 of the exterior wall portion 32 is also provided with a light-transmitting window portion 35 that allows light to enter the atrium space 19. The floor of the second floor living room 33 is set at the same height as the floor portion 18 of the second floor space 16, and the ceiling of the second floor living room 33 is set at the same height as the ceiling portion 23 of the second floor space 16.

As described above, the house 10 is a modular house constructed by combining multiple rectangular building units. Below, we will explain the configuration of building unit 40, which is one of the building units that make up the house 10 and is equipped with a skip floor section 26.

As shown in Figure 3, the building unit 40 has four pillars 41 arranged at its four corners, and four ceiling girders 42 and floor girders 43 that connect the upper and lower ends of each pillar 41, respectively. These pillars 41, ceiling girders 42, and floor girders 43 form a rectangular parallelepiped frame.

On the floor of the building unit 40, intermediate floor beams 47 are installed between the middle sections of the floor girders 43 on the opposing long sides. On the ceiling of the building unit 40, intermediate ceiling beams 48 are installed between the middle sections of the ceiling girders 42 on the long sides. The intermediate ceiling beams 48 are positioned directly above the intermediate floor beams 47, and face each other vertically.

Although not shown in the figures, multiple ceiling joists are installed at predetermined intervals between opposing ceiling girders 42 on the long sides of the building unit 40, and these ceiling joists support the ceiling surface material of the second floor portion 12. Multiple floor joists are installed at predetermined intervals between opposing floor girders 43 on the long sides of the building unit 40, and these floor joists support the floor surface material of the second floor portion 12. Furthermore, in the floor portion of the building unit 40, no floor joists are installed between the intermediate floor joist 47 and the floor joist 43 on one short side. Therefore, a floor opening 49 is formed in the floor portion of the building unit 40, surrounded by the intermediate floor joist 47, the floor joist 43 on the short side, and each floor joist 43 on the long side. The floor opening 49 constitutes the high-rise opening 24.

The building unit 40 has center columns 51 and 52. The center column 51 is provided across the vertically opposing floor beams 43 and ceiling beams 42. The center column 52 is provided across the vertically opposing intermediate floor beams 47 and intermediate ceiling beams 48. The center columns 51 are located on both ends of the floor beams 43, and the center columns 52 are located on both ends of the intermediate floor beams 47. In this case, each center column 51 and each center column 52 are located at the same position in the longitudinal direction of the floor beams 43, 45.

A skip floor section 26 is installed between the center columns 51, 52. The skip floor section 26 is composed of a floor surface material 53 that forms the floor surface of the storage space 25, a ceiling surface material 61 that forms the ceiling surface of the open-ceiling space 19, and a support frame 57 that is installed between the floor surface material 53 and the ceiling surface material 61 and supports the double-sided materials 53, 61.

The floor surface material 53 is composed of a subfloor surface material 54 and a floor finish surface material 55. The subfloor surface material 54 is made of rectangular plywood. The floor finish surface material 55 is made of flooring and is laid on top of the subfloor surface material 54. The ceiling surface material 61 is made of rectangular gypsum board.

The support frame 57 has a pair of support beams 58 spanning the middle of the opposing center posts 51, 52, and multiple small beams 59 spanning between each support beam 58. Each support beam 58 is fixed to the center posts 51, 52. Each support beam 58 and small beam 59 is made of wooden timber and is connected using nails, etc.

A floor surface material 53 is placed on the upper surface of the support frame 57. The floor surface material 53 is fixed to the support frame 57 with screws or the like. A ceiling surface material 61 is fixed to the underside of the support frame 57 with screws or the like. In addition to the support frame 57, electrical wiring (not shown) is also provided in the space between the floor surface material 53 (subfloor surface material 54) and the ceiling surface material 61.

In order to allow outside light into the storage space 25 and the atrium space 19, it is possible to provide light-receiving windows in the exterior wall 32. In this case, it is possible to provide separate light-receiving windows in the storage space 25 and the atrium space 19 in the second floor section 12 of the exterior wall 32. However, if this is done, the height of the light-receiving windows will be significantly smaller than the height of the other light-receiving windows 34 also provided in the exterior wall 32. In this case, when the house 10 is viewed from the outside, the balance between the light-receiving windows will be poor, which could detract from the appearance of the house 10.

In this embodiment, the house 10 is provided with a lighting window 62 in the second floor section 12 of the exterior wall 32, extending vertically across the skip floor 26. The configuration of the lighting window 62 will be explained below with reference to Figures 1, 2, and 4 as appropriate. Note that Figure 4 is a perspective view of the lighting window 62 as seen from the storage space 25 side, and for ease of explanation, the skip floor 26 has been omitted from the illustration.

As shown in Figure 4, a window opening 63 is formed in the exterior wall portion 32. The window opening 63 is a slit-shaped opening that extends vertically and connects the indoors and outdoors. The window opening 63 extends vertically across the skip floor portion 26.

A light-receiving window 62 is provided in the window opening 63. The light-receiving window 62 is located closer to the exterior of the window opening 63 (see Figure 1). The light-receiving window 62 is a fixed slit window and includes a window pane 64 and a window frame sash 65. The window pane 64 is formed in the shape of a rectangular plate. The window frame sash 65 is provided around the periphery of the window opening 63, with the window pane 64 attached to its inside.

The frame 66 is located on the indoor side of the light-receiving window portion 62 in the window opening 63. The frame 66 is arranged around the periphery of the window opening 63. The frame 66 has an upper frame portion extending along the upper edge of the window opening 63, a lower frame portion extending along the lower edge of the window opening 63, and a pair of side frame portions 66a extending along each side edge of the window opening 63. The frame 66 corresponds to a window frame.

As shown in Figures 2 and 4, multiple (specifically, three) daylighting windows 62 are provided side by side. The height dimension of each daylighting window 62 is the same as the height dimension of the daylighting window 34. This ensures balance between each daylighting window 62 and the daylighting window 34. Furthermore, the daylighting windows 62 (window glass 64) extend vertically across the skip floor 26. This allows light to enter the storage space 25 and the atrium space 19 through the daylighting windows 62. This makes it possible to introduce external light into the storage space 25 and the atrium space 19 while minimizing damage to the appearance of the house 10.

In this embodiment, the configuration in which the light-receiving window 62 is installed across the skip floor 26 from above and below is expected to make the skip floor 26 visible from the outdoors through the light-receiving window 62. Because the skip floor 26 is composed of a floor surface material 53 and a ceiling surface material 61, in this case, there is a risk that components such as the support frame 57 and electrical wiring arranged between the floor surface material 53 and the ceiling surface material 61 may also be visible from the outdoors. If this happens, these normally invisible components may become visible, which could significantly impair the appearance of the house 10.

In consideration of this, in this embodiment, a cover member 71 is provided between the light-receiving window portion 62 and the skip floor portion 26, and this cover member 71 conceals the space between the floor surface material 53 and the ceiling surface material 61. The cover member 71 will be described below with reference to Figures 5 to 7. Note that for ease of explanation, the cover member 71 is indicated by dot hatching in Figures 6 and 7.

As shown in Figures 5 to 7, the cover member 71 is composed of a main body 72 and a first bracket 83 and a second bracket 85 attached to the main body 72. The cover member 71 is provided for each light-receiving window 62 and is positioned between the light-receiving window 62 and the skip floor 26.

The main body 72 is formed by bending a steel plate. It comprises a cover portion 73, an extension portion 74, and a rising portion 78. The entire main body 72 is painted (colored) black.

The covering portion 73 extends vertically and is positioned between the light-receiving window portion 62 and the skip floor portion 26 in the window opening 63. The covering portion 73 is positioned opposite the light-receiving window portion 62 and conceals the space between the ceiling surface material 61 and the floor surface material 53 from the light-receiving window portion 62 side. Specifically, the covering portion 73 conceals the area from the underside of the ceiling surface material 61 to the vertical middle of the floor surface material 53 (specifically, the subfloor surface material 54). This prevents the space between the ceiling surface material 61 and the floor surface material 53 from being seen from the outdoors through the light-receiving window portion 62. The covering portion 73 is positioned in the indoor-outdoor middle of the window opening 63 and extends widthwise (in the same direction as the widthwise direction of the light-receiving window portion 62) across each side frame portion 66a of the frame 66. The widthwise length of the covering portion 73 is the same as the spacing between each side frame portion 66a.

The extension portion 74 extends horizontally from the upper end of the cover portion 73 toward the light-receiving window portion 62. The end of the extension portion 74 on the light-receiving window portion 62 side extends to a position close to the light-receiving window portion 62. This prevents objects from falling from the storage space 25 into the open-ceiling space 19 through the gap between the skip floor portion 26 and the light-receiving window portion 62. In addition, the rising portion 78 rises upward from the end of the extension portion 74 on the light-receiving window portion 62 side.

A long rectangular beam 81 is provided on the surface of the cover portion 73 facing the skip floor portion 26. The beam 81 extends along the upper edge of the cover portion 73, and more specifically, extends along the entire upper edge. The beam 81 is fixed to the cover portion 73 with screws 89. The upper surface of the beam 81 is flush with the upper surface of the extension portion 74.

The first bracket 83 is attached to the cover portion 73 of the main body 72 via a square bar 81 (see Figure 5). In other words, the first bracket 83 is attached on the opposite side of the square bar 81 from the cover portion 73. The first bracket 83 is formed in an L-shape from steel plate and has a pair of plate portions 83a, 83b that are perpendicular to each other. Of each plate portion 83a, 83b, one plate portion 83a is fixed with a screw 89 to the surface of the square bar 81 opposite the cover portion 73. The other plate portion 83b extends from the upper end of the plate portion 83a to the side opposite the light-receiving window portion 62 (see Figure 6). The other plate portion 83b is located above the upper surfaces of the extension portion 74 and the square bar 81. Multiple first brackets 83 (specifically, two) are provided at intervals across the width of the cover portion 73 (see Figure 7).

The plate portion 83b of the first bracket 83 is placed on the upper surface of the underfloor surface material 54. A recess 54b is formed in the underfloor surface material 54, in which the plate portion 83b is placed. The recess 54b is open upward and toward the light-receiving window 62. When the plate portion 83b is placed in this recess 54b, the upper surface of the plate portion 83b is flush with the upper surface of the underfloor surface material 54. In addition, a screw hole 83c is formed in the plate portion 83b, penetrating it in the thickness direction. A screw 89 is inserted into the screw hole 83c, and the plate portion 83b is fixed to the underfloor surface material 54 by the screw 89. This fixes the first bracket 83, and therefore the cover member 71, to the skip floor section 26.

As described above, the floor finishing surface material 55 is laid on the upper surface of the subfloor surface material 54. The plate portion 83b is positioned between the floor finishing surface material 55 and the subfloor surface material 54. This makes it possible to make the plate portion 83b invisible from within the storage space 25. The plate portion 83b corresponds to the placement portion.

The second brackets 85 are provided on both widthwise sides of the covering portion 73. Each second bracket 85 is located at the bottom of the covering portion 73. Each second bracket 85 is formed in an L-shape from steel plate and has a pair of plate portions 85a, 85b that are perpendicular to each other. Of each plate portion 85a, 85b, one plate portion 85a is fixed by welding to the plate surface of the covering portion 73 on the skip floor portion 26 side. The other plate portion 85b extends from the plate portion 85a to the side opposite the light-receiving window portion 62 (see Figure 6). In this case, each plate portion 85b extends from the widthwise end of the covering portion 73, i.e., from the side end of the covering portion 73, to the side opposite the light-receiving window portion 62, and is arranged with its plate surfaces facing each other.

The outer surface of each plate portion 85b abuts against the inner surface of the side frame portion 66a. While in this abutting state, each plate portion 85b is fixed to the side frame portion 66a with a screw 89. Specifically, each plate portion 85b has a screw hole 85c that penetrates through the plate thickness, and a screw 89 is inserted into the screw hole 85c. As a result, for the second bracket 85, the cover member 71 is fixed to the frame 66. The plate portion 85b corresponds to the fixing portion.

A subfloor surface material 76, separate from the subfloor surface material 54, is placed on the upper surfaces of the extension portion 74 and the square timber 81. The subfloor surface material 76 is made of wooden plywood. The subfloor surface material 76 is arranged across the entire upper surface of the extension portion 74 and the upper surface of the square timber 81. The upper surfaces of the subfloor surface materials 54, 76 are flush with each other. In addition, a portion of the floor finishing surface material 55 (hereinafter referred to as floor portion 55a) is superimposed on the upper surface of the subfloor surface material 76. A portion of the floor finishing surface material 55 extends further toward the light-receiving window portion 62 than the subfloor surface material 54, and this extended portion forms the floor portion 55a. The floor portion 55a is superimposed on the entire upper surface of the subfloor surface material 76. This allows the upper surfaces of the extension portion 74 and the square timber 81 to be concealed. For convenience, the floor finishing surface material 55, floor portion 55a, and subfloor surface material 76 are not shown in Figure 7. The floor portion 55a corresponds to "part of the floor finishing surface material" as defined in the claims.

A rising portion 78 of the main body 72 is positioned closer to the light-receiving window 62 than the vertically overlapping underfloor surface material 76 and floor portion 55a. The height of the rising portion 78 is approximately the same as the sum of the thicknesses of the floor portion 55a and the underfloor surface material 76 (see Figure 6). As a result, the rising portion 78 conceals the floor portion 55a and the underfloor surface material 76 from the light-receiving window 62 side. This makes it possible to prevent the floor portion 55a and the underfloor surface material 76 from being seen through the light-receiving window 62 from the outside.

In addition, the cover member 71 generally conceals the area from the underside of the ceiling surface material 61 to the upper surface of the floor finishing surface material (floor portion 55a) from the lighting window 62 side. This makes it possible to prevent the entire height of the skip floor section 26 from being seen through the lighting window 62 from the outside.

The configuration of this embodiment described above provides the following excellent effects:

In the above embodiment, because the light-receiving window 62 extends across the skip floor 26 from top to bottom, the size of the light-receiving window 62 is not limited by the skip floor 26. This ensures a balance between the light-receiving window 62 and the other light-receiving window 34. Furthermore, because the light-receiving window 62 extends across the skip floor 26 from top to bottom, it is possible to admit light into both the open-ceiling space 19 and the storage space 25. This makes it possible for a house 10 equipped with a skip floor 26 to admit external light into both the open-ceiling space 19 and the storage space 25 while minimizing damage to the exterior appearance.

In the configuration of the above embodiment, in which the light-transmitting window 62 is installed across the skip floor 26 from above and below, it is anticipated that the skip floor 26 will be visible through the light-transmitting window 62 from the outside. Because the skip floor 26 is composed of the ceiling surface material 61 of the atrium space 19 and the floor surface material 53 of the storage space 25, in this case, there is a risk that components such as the support frame 57 and electrical wiring arranged between the floor surface material 53 and the ceiling surface material 61 will also be visible from the outside. If this happens, these normally invisible components will become visible, which could significantly impair the appearance of the house 10.

In light of this, in the above embodiment, a cover member 71 is provided between the light-receiving window 62 and the skip floor section 26, and this cover member 71 conceals the space between the floor surface material 53 and the ceiling surface material 61 in the skip floor section 26 from the light-receiving window 62 side. This makes it possible to prevent the space between the floor surface material 53 and the ceiling surface material 61 from being seen from the outside through the light-receiving window 62, thereby preventing significant impairment to the appearance of the house 10.

In the above embodiment, the light-receiving window 62 is positioned closer to the exterior of the window opening 63. Therefore, in a configuration in which the light-receiving window 62 spans the skip floor 26, the light-receiving window 62 and the skip floor 26 are spaced apart. This raises the concern that items in the storage space 25 may fall into the open-ceiling space 19 through the gap between the light-receiving window 62 and the skip floor 26. Therefore, in the above embodiment, the cover member 71 has a covering portion 73 that conceals the space between the ceiling surface material 61 and the floor surface material 53, and an extension portion 74 that extends from the covering portion 73 toward the light-receiving window 62. In this case, the extension portion 74 covers the gap between the light-receiving window 62 and the skip floor 26. This prevents items in the storage space 25 from falling into the open-ceiling space 19.

If the extension 74 is provided between the light-receiving window 62 and the skip floor 26, there is a concern that the external light let in through the light-receiving window 62 will be blocked by the extension 74, limiting the amount of light entering the area below the extension 74, i.e., the open-ceiling space 19. According to the above embodiment, the extension 74 extends from the upper end of the cover 73. This prevents the extension 74 from limiting the amount of light entering the open-ceiling space 19. Therefore, light can be more effectively let into the open-ceiling space 19.

In the above embodiment, the extension portion 74 is covered from above by a portion of the floor finishing surface material 55 (floor portion 55a), which prevents the extension portion 74 from spoiling the appearance of the storage space 25. Furthermore, even if the extension portion 74 becomes hot due to sunlight, it is possible to prevent the occupant from touching the extension portion 74.

In the above embodiment, the floor portion 55a and subfloor surface material 76 placed on the upper surface of the extension portion 74 can be concealed from the light-receiving window portion 62 side by the rising portion 78. This prevents the floor portion 55a and subfloor surface material 76 from being seen through the light-receiving window portion 62 from the outside, more reliably avoiding damage to the appearance of the house 10.

In addition, the raised portion 78 helps prevent the floor portion 55a and the subfloor surface material 76 from shifting.

In the above embodiment, the second bracket 85 extends from the side end of the cover portion 73 on the side opposite the light-receiving window portion 62. This makes it possible to make the second bracket 85 invisible from the outdoors through the light-receiving window portion 62, thereby more reliably preventing the appearance of the house 10 from being marred.

Furthermore, a frame 66 is disposed around the periphery of the window opening 63, and the light-receiving window 62 is disposed on the outdoor side of the frame 66. In the above embodiment, with this configuration, the cover 73 is disposed in the inner area surrounded by the frame 66, and more specifically, in the middle of this inner area in the indoor-outdoor direction. This allows the second bracket 85 to be fixed to the frame 66, even if the second bracket 85 extends from the side edge of the cover 73 on the side opposite the light-receiving window 62.

In the above embodiment, the cover member 71 has a first bracket 83. The plate portion 83b of the first bracket 83 is placed on the upper surface of the subfloor surface material 54. In this case, the height position of the cover member 71 is determined by the plate portion 83b. This makes it easy to align the cover member 71 when fixing it to the skip floor portion 26.

Furthermore, the plate portion 83b is positioned sandwiched between the subfloor surface material 54 and the floor finishing surface material 55. As a result, the plate portion 83b is covered from above by the floor finishing surface material 55, preventing the plate portion 83b from spoiling the appearance of the storage space 25.

If a cover member 71 is provided between the light-receiving window 62 and the skip floor 26, there is a concern that the cover member 71 (main body 72) may be visible through the light-receiving window 62 from the outdoors. According to the above embodiment, the entire main body 72 is painted (colored) black. This prevents the cover member 71 from being too visible through the light-receiving window 62, more reliably preventing the appearance of the house 10 from being marred.

The present invention is not limited to the above embodiment and may be implemented, for example, as follows.

(1) In the above embodiment, the lower space is an open-ceiling space 19, but this is not limited to this. In other words, the lower space is not limited to one that spans multiple floors. For example, the floor of the lower space may be set at the same height as the floor 18 of the second-floor space 16.

(2) In the above embodiment, the upper space is a storage space 25, but this is not limited to this. For example, it may be a living room.

(3) In the above embodiment, a skip floor section 26 is provided on the second floor section 12 of the house 10, but this is not limited to this. For example, a skip floor section may be provided on the first floor section of the house. In this case, the ceiling of the upper space section may be set at the same height as the ceiling of the first floor space 15, making the upper space section a low-ceilinged space, or the ceiling of the upper space section may be set at the same height as the ceiling of the second floor space 16, making the upper space section an open-ceiling space.

(4) In the above embodiment, a cover member 71 is provided between the light-receiving window portion 62 and the skip floor portion 26, but the cover member 71 is not a required component. However, it is preferable to provide a cover member in order to prevent the skip floor portion from spoiling the appearance of the house.

(5) In the above embodiment, the light-receiving window 62 is a slit window, but this is not limited to this. In other words, the width of the light-receiving window is not particularly limited.

(6) In the above embodiment, one cover member 71 is provided for one light-receiving window section 62, but this is not limited to this. For example, multiple cover members may be provided side by side for one light-receiving window section. In this case, it is preferable to provide the multiple cover members close to each other to prevent the skip floor section from being visible through the gaps between the multiple cover members.

(7) In the above embodiment, the cover member 71 is composed of the main body 72, the first bracket 83, the second bracket 85, and the square bar 81, but these components do not need to be separate components. In other words, the entire cover member may be formed as a single component.

(8) The material of the cover member is not particularly limited as long as it ensures sufficient strength. For example, it may be made of resin.

(9) In the above embodiment, the entire body 72 is colored (painted) black, but this is not limited to this. The entire body 72 does not necessarily have to be colored, as long as at least the surface of the cover member facing the light-receiving window is colored. Furthermore, the color is not limited to black. For example, it may be colored a dark shade (dark color) such as dark gray or dark blue. Furthermore, the coloring method is not limited to painting the surface. For example, a coloring agent may be added when manufacturing the material of the cover member to achieve a dark color.

(10) In the above embodiment, the cover member 71 is provided with an extension 74, but the extension 74 is not a required component. For example, a blocking member separate from the cover member may be provided between the cover member and the light-receiving window portion.

(11) In the above embodiment, the cover member 71 is provided with a raised portion 78, but the raised portion 78 is not a required component. However, if a flooring material or the like is to be placed on the upper surface of the extension portion, it is preferable to provide a raised portion from the perspective of ensuring aesthetics. Furthermore, it is preferable to set the height dimension of the raised portion so that it can completely cover the flooring material or the like from the light-receiving window side.

(12) In the above embodiment, the first bracket 83 is attached to the cover portion 73 via a square beam 81, but the square beam 81 is not a required component. However, because the square beam 81 can be used to adjust the position of the cover portion 73 in the indoor/outdoor direction, it is possible to position the cover portion 73 in the middle of the window opening 63 in the indoor/outdoor direction with a simple configuration.

(13) In the above embodiment, the second bracket 85 extends from the cover portion 73 on the side opposite the light-receiving window portion 62, but this is not limited to this. The fixing portion may extend from the cover portion toward the light-receiving window portion. However, in this case, there is a risk that the fixing portion may be visible through the light-receiving window portion from the outside, so the configuration of the above embodiment is preferred.

(14) In the above embodiment, the first bracket 83 and the second bracket 85 are provided, but these are not essential components. For example, the cover portion may be fixed to the underside of the subfloor surface material using an L-shaped angle or the like.

(15) In the above embodiment, the extension portion 74 extends from the upper end of the cover portion 73, but the position at which the extension portion is provided on the cover portion is not limited to the upper end. However, from the perspective of optimally admitting light to the lower space, the configuration of the above embodiment is preferable.

(16) In the above embodiment, the floor surface material 53 of the skip floor section 26 is composed of the subfloor surface material 54 and the floor finishing surface material 55, but this is not limited to this. The floor surface material of the skip floor section may also be composed of a single surface material.

(17) In the above embodiment, the floor portion 55a placed on the upper surface of the extension 74 is part of the floor finishing surface material 55, but this is not limited to this. A different floor surface material adjacent to the floor surface material that constitutes the skip floor portion may also be placed on the upper surface of the extension.

(18) In the above embodiment, the house 10 is two-story, but this is not limited to this. For example, it may be three-story or one-story. Furthermore, while the above embodiment is applied to a modular house, it may also be applied to houses built using other construction methods, such as steel frame construction or traditional wooden construction.
