DETAILED DESCRIPTION OF THE INVENTION

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which like reference numerals denote like or corresponding parts and will not be described repeatedly.

[0014] <Regarding the First Embodiment> (About the overview) A house 1 according to this embodiment will be described with reference to Figures 1(A) and (B). Figure 1(A) is a partial perspective view that schematically shows the framework of a house with a sloped roof according to this embodiment 1. Figure 1(A) shows only a portion of the framework of the sloped roof. Figure 1(B) is an enlarged plan view showing the area around the multi-window in Figure 1(A).

[0015] The house 1 is a building for people to live in. The house 1 is generally a wooden structure and is made up of multiple pieces of wood. The house 1 is typically a detached house, but may also be an apartment building (such as a row house) with multiple independent dwelling units. The house 1 may be multi-story or single-story.

[0016] Although not shown in Figure 1(A), the house 1 is provided with a base that is set on a foundation poured into the ground, multiple pillars that protrude upward from the base and are set along the exterior walls (exterior walls) of the house 1, and beams that extend horizontally and are spanned over the multiple pillars to transmit the load of the sloped roof 2 to the pillars.

[0017] The house 1 has a sloped roof 2. In Figure 1(A), a hip roof is shown as the sloped roof 2, but it can also be a gable roof, a shed roof, or any other roof that slopes downward from top to bottom.

[0018] (About sloped roofs) The sloped roof 2 in this embodiment will be described in detail. The sloped roof 2 comprises a ridge beam 3 extending in the girder direction, an eaves beam 4 located below the ridge beam 3 and extending in the girder direction, multiple purlins 5 located between the ridge beam 3 and the eaves beam 4 and extending in the girder direction, and multiple rafters 6 spanning over the ridge beam 3, eaves beam 4, and purlins 5 and forming eaves edges 60 below the eaves beam 4. In Figure 1(B), the girder direction is indicated by arrow A1. The slope of the sloped roof 2 is preferably 6.0 sun or less.

[0019] The ridge beam 3 is located at the highest point of the sloped roof 2, and the top of the sloped roof 2 is supported by the ridge beam 3.

[0020] The eaves beam 4 is installed parallel to the ridge beam 3 and is installed at the lowest point of the sloped roof 2. The eaves beam 4 is supported by the above-mentioned multiple pillars. As a result, the eaves beam 4 is installed along the outer wall (periphery) of the house 1.

[0021] Multiple purlins 5 are installed in parallel between the ridge beam 3 and the eaves beam 4. In the example shown in Figure 1 (A), three purlins 5 are installed: the first purlin 51 at the bottom, the third purlin 53 at the top, and the second purlin 52 installed between them, but this is not limited to this. It is sufficient that at least one purlin 5 is installed. The first purlin 51 at the bottom is the purlin closest to the eaves beam 4.

[0022] The upper edges of the multiple rafters 6 are supported on the ridge beam 3 (FIG. 1(A)), the lower edges are supported on the gable base 54 (FIG. 1(B)), and the lower ends are supported on the eaves beam 4 (FIGS. 1(A) and 1(B)). As a result, the rafters 6 form an eaves tip 60 below the eaves beam 4. In other words, below the rafters 6, eaves protrude outward from the wall of the house 1. For strength reasons, the length of the eaves L1 (the length protruding downward from the eaves beam 4) is 1,000 cm or less, preferably 990 cm or less. The gable base 54 extends along the girder direction and is preferably not interrupted at a position facing the continuous window 8. As particularly shown in FIG. 4, an eaves gutter 55 (shown by a dashed line) may be provided along the girder direction on the outdoor side of the gable base 54 to collect rainwater and channel it outward.

[0023] The multiple rafters 6 are arranged perpendicular to the ridge beam 3, eaves beams 4, and purlins 5, and although five are provided in the example shown in Fig. 1(A), the number is not limited to this. Also, as shown in Fig. 4, sheathing boards 21 are placed above the rafters 6, and multiple roof materials 22 are laid above the sheathing boards 21. The multiple rafters 6 will be described later.

[0024] (About multi-window windows) A continuous window 8 is provided between the eaves beam 4 and the lowest purlin 51. The continuous window 8 is a series of skylights connected in the girder direction and includes a first skylight 81 and a second skylight 91. In this embodiment, two skylights are connected in a row, but this is not limited to this and more than two skylights may be provided. The first and second skylights 81, 91 are windows that efficiently let sunlight into the indoor space. The first and second skylights 81, 91 may be closed windows (fixed windows) or may be openable and closable windows. The first and second skylights 81, 91 preferably have the same shape, but may have different widths in the girder direction or in a direction perpendicular to the girder direction. In other words, it is sufficient that at least a portion of the skylights 81, 91 overlap in the girder direction.

[0025] 1(B), the first skylight 81 includes a covering portion 82 and an upper frame 83, a lower frame 84, a left frame 85, and a right frame 86 that surround the covering portion 82. Similarly, the second skylight 91, located to the left of the first skylight 81 in the longitudinal direction, includes a covering portion 92 and an upper frame 93, a lower frame 94, a left frame 95, and a right frame 96 that surround the covering portion 92. The covering portions 82, 92 have high translucency that allows at least a portion of sunlight to pass through. The covering portions 82, 92 are planar members typically made of transparent glass.

[0026] (About rafters) The plurality of rafters 6 will be further described in detail with reference to Figures 2 to 4. Figure 2 is a cross-sectional view taken along line II in Figure 1(B), Figure 3 is an enlarged cross-sectional view of a portion of Figure 2, and Figure 4 is a cross-sectional view taken along line IV in Figure 1(B).

[0027] As described above, a plurality of rafters 6 are provided. For ease of understanding, as shown in Figure 1(A), the rafters located on the right side in the longitudinal direction are referred to as the first rafter 61, the second rafter 62, the third rafter 63, and the fourth rafter 64, in that order, and the auxiliary rafter provided between the first rafter 61 and the second rafter 62 is referred to as the first auxiliary rafter 71, and the auxiliary rafter provided between the second rafter 62 and the third rafter 63 is referred to as the second auxiliary rafter 72. It is preferable that the intervals in the longitudinal direction between these rafters 61 to 64 and the auxiliary rafters 71, 72 are equal.

[0028] The multi-window window 8 is supported at both ends by two rafters spaced apart from one another. Specifically, the multi-window window 8 is fixed at both ends by a first rafter 61 and a third rafter 63. Furthermore, the first skylight 81 and second skylight 91 that make up the multi-window window 8 are fixed together by a second rafter 62.

[0029] The first to third rafters 61 to 63 supporting the continuous window 8 have a structure with increased strength compared to the other rafters (the fourth rafter 64 in Figure 1 (B)). Specifically, the first to third rafters 61 to 63 are an assembly of multiple rafters. More specifically, as shown in Figure 2, the first rafter 61 is a shape in which three rod-shaped rafters 61a, 61b, and 61c are stacked in the longitudinal direction and closely packed together. Similarly, the second rafter 62 is a shape in which three rod-shaped rafters 62a, 62b, and 62c are stacked in the longitudinal direction and closely packed together, and the third rafter 63 is a shape in which three rod-shaped rafters 63a, 63b, and 63c are stacked in the longitudinal direction and closely packed together. It is preferable that the rod-shaped rafters 61a to 61c, 62a to 62c, and 63a to 63c mentioned above have the same shape as the fourth rafter 64.

[0030] The three rod-shaped rafters 61a, 61b, and 61c that make up the first rafter 61 may be glued together at their sides in the longitudinal direction, or may be fixed with screws, for example. The same applies to the rod-shaped rafters 62a, 62b, and 62c that make up the second rafter 62 and the rod-shaped rafters 63a, 63b, and 63c that make up the third rafter 63. Note that although the first to third rafters 61 to 63 are shown in a simplified manner in Figure 1(A), in reality, multiple rod-shaped rafters are stacked as shown in Figures 1(B) and 2.

[0031] 1(A) and 1(B), a single first auxiliary rafter 71 is provided between the first and second rafters 61, 62 supporting the first skylight 81, and is separated by the first skylight 81. Similarly, a single second auxiliary rafter 72 is provided between the second and third rafters 62, 63 supporting the second skylight 91, and is separated by the second skylight 91. In this embodiment, one auxiliary rafter 71 is provided between each of the rafters 61, 62 or rafters 62, 63 supporting the skylights 81, 91, but the number of auxiliary rafters 71, 72 does not necessarily have to be one, and two or more auxiliary rafters may be provided.

[0032] As shown in Figures 1(B) and 4 in particular, the first auxiliary rafter 71 is divided into two parts, one above the other, with the first skylight 81 in between. The lower end of the upper first auxiliary rafter 71 abuts against the upper frame 83 of the first skylight 81, and the upper end of the lower first auxiliary rafter 71 abuts against the lower frame 84 of the first skylight 81. Similarly, as shown in Figure 1(B), the second auxiliary rafter 72 is divided into two parts, one above the other, with the second skylight 91 in between. The lower end of the upper second auxiliary rafter 72 abuts against the upper frame 93 of the second skylight 91, and the upper end of the lower second auxiliary rafter 72 abuts against the lower frame 94 of the second skylight 91.

[0033] Next, the fixing of the right side in the girder direction of the first skylight 81 will be described. As shown in FIG. 1(B), the right frame 86 of the first skylight 81, which is located on the right side in the girder direction, is supported by the rod-shaped rafter 61c of the first rafter 61. Specifically, as shown in FIG. 2, the rod-shaped rafter 61c is fixed to the right-side support pier 41, and the right frame 86 is fixed to the right-side support pier 41 with screws or the like via the first girder 31. It is preferable that the rod-shaped rafter 61c be fixed not only to the right-side support pier 41 but also to the right-side edge support 43 with screws or the like.

[0034] The fixing of the left side of the second skylight 91 in the girder direction will now be described. As shown in FIG. 1(B), the left frame 95 of the second skylight 91, located on the left side in the girder direction, is supported by the rod-shaped rafter 63a of the third rafter 63. Specifically, as shown in FIG. 2, the rod-shaped rafter 63a is fixed to the left support pier 42, and the left frame 95 is fixed to the left support pier 42 with screws or the like via the second girder 32. It is preferable that the rod-shaped rafter 63a be fixed not only to the left support pier 42 but also to the left side edge support 44 with screws or the like.

[0035] Finally, the fixation between the first skylight 81 and the second skylight 91 will be described. As shown in FIG. 1(B), the left frame 85 of the first skylight 81, which is located on the right side in the longitudinal direction, is supported by the rod-shaped rafter 62a of the second rafters 62, and the right frame 96 of the second skylight 91, which is located on the left side in the longitudinal direction, is supported by the rod-shaped rafter 62c of the second rafters 62. Specifically, as shown in FIG. 2, a U-shaped third flashing 33 is provided between the left frame 85 of the first skylight 81 and the right frame 96 of the second skylight 91, and the left frame 85 of the first skylight 81 is fixed to the rod-shaped rafter 62a, and the right frame 96 of the second skylight 91 is fixed to the rod-shaped rafter 62c via the third flashing 33.

[0036] Referring to FIG. 3, the second rafter 62 located between the first skylight 81 and the second skylight 91 will be described in detail. The second rafter 62 includes a reinforcing plate 65 to increase the strength of the rafter. In this embodiment, the reinforcing plate 65 is a plate-like member formed, for example, of a steel plate or a synthetic resin, and four reinforcing plates 65 are provided. The reinforcing plates 65 are provided along the longitudinal direction of the second rafter 62 and have the same dimension as the longitudinal dimension of the second rafter 62. Specifically, a first reinforcing plate 65a is provided on the right side of the first rod-shaped rafter 62a in the longitudinal direction, a second reinforcing plate 65b is provided between the first rod-shaped rafter 62a and the second rod-shaped rafter 62b, a third reinforcing plate 65c is provided between the second rod-shaped rafter 62b and the third rod-shaped rafter 62c, and a fourth reinforcing plate 65d is provided on the left side of the third rod-shaped rafter 62c in the longitudinal direction. These reinforcing plates 65a-65d are preferably fixed to the rod-shaped rafters 62a-62c by passing screws or the like through them in the longitudinal direction. By providing the reinforcing plates 65 on both sides of the second rafter 62 and between the rod-shaped rafters 62a, 62b, 62c in this manner, the strength of the second rafter 62 in the longitudinal direction can be improved.

[0037] Referring to the same figure, the first rod-shaped rafter 62a is fixed to the first base pier 45 via a screw or the like. Similarly, the third rod-shaped rafter 62c is fixed to the second base pier 46 via a screw or the like. Furthermore, the second rafter 62, the first base pier 45, and the second base pier 46 are preferably surrounded on three sides by gypsum boards 47, 48, and 49.

[0038] (Indoor spaces) With reference to Figure 5, we will explain the indoor space when a continuous window 8 is installed between the eaves beam 4 and the lowest main building 51. Figure 5 shows a schematic diagram of an example of an indoor space. In Figure 5, areas other than those into which light shines through the continuous window 8 are indicated in light ink.

[0039] If a continuous window 8 is installed between the eaves beam 4 and the lowest main building 51, that is, close to the exterior wall of the house 1, the indoor space will be visually brighter, allowing for a dramatic spatial presentation, as shown in Figure 5. In particular, if a continuous window 8 is installed close to the exterior wall of the house 1 and in an interior corner, it will be possible to beautifully illuminate two walls of the indoor space with sunlight streaming in through the continuous window 8. When the house 1 is multi-story, the staircase is often installed against the exterior wall, making it possible to create an even brighter, more dramatic space near the staircase.

[0040] Furthermore, when installing a skylight, it is preferable that the wall surface onto which sunlight shines through the skylight be flat and without any irregularities. This allows sunlight to hit the wall surface, creating a beautiful indoor space with sunlight. Furthermore, it is preferable that no other windows be placed near the surface of the multi-window 8 onto which sunlight shines. This prevents unnecessary light from disrupting the gradation of shadows created by the light from the multi-window 8, making it possible to create a more beautiful indoor space.

[0041] (About the action) In conventional sloped roofs, the rafters that form the eaves at their lower ends are placed on the eaves beams, so the rafters must have a certain level of strength. However, placing a skylight on the eaves beams creates a problem of insufficient strength, making it impossible to place a skylight on the eaves beams. In this embodiment, the strength of the rafters 61, 62, and 63 that support the continuous window 8 is increased compared to the other rafters, allowing skylights 81 and 91 to be placed on the eaves beams 4.

[0042] By making the second rafter 62 located between the two skylights 81, 91 stronger than the first and third rafters 61, 63 located on either side of the continuous window 8, the two skylights 81, 91 can be connected in the rafter direction to form the continuous window 8. Furthermore, the continuous window 8 can be placed anywhere above the eaves rafter 4, which broadens the range of spatial design options.

[0043] <Regarding the second embodiment> An example of the configuration of a house 1A according to this embodiment will be described with reference to Fig. 6. Only differences from house 1 shown in embodiment 1 will be described in detail below.

[0044] On the sloped roof 2A of the house 1A, a continuous window 8A is provided between the second purlin 52 and the third purlin 53. The continuous window 8A consists of three windows: a first skylight 81A, a second skylight 91A, and a third skylight 101A, which are arranged consecutively in the longitudinal direction. It is preferable that the three windows, the first skylight 81A, the second skylight 91A, and the third skylight 101A, have the same shape.

[0045] The first to third rafters 61 to 63 supporting the continuous window 8 have a structure with increased strength compared to the other rafters (the fifth rafter 66A in FIG. 6(B)). Specifically, the first rafter 61A located on the right side of the continuous window 8A in the longitudinal direction and the fourth rafter 64A located on the left side of the continuous window 8A in the longitudinal direction have a structure with increased strength compared to the second rafter 62A and the third rafter 63A located between the continuous window 8A. The first rafter 61A of this embodiment is the same as the first rafter 61 of the first embodiment described above, and the fourth rafter 64A of this embodiment is the same as the third rafter 63 of the first embodiment described above. The second rafter 62A and the third rafter 63A of this embodiment are the same as the second rafter 62 of the first embodiment described above.

[0046] Two auxiliary rafters are provided between adjacent rafters. Specifically, two auxiliary rafters 71A and 72A are provided between the first rafter 61A and the second rafter 62A, two auxiliary rafters 73A and 74A are provided between the second rafter 62A and the third rafter 63A, and two auxiliary rafters 75A and 76A are provided between the third rafter 63A and the fourth rafter 64A. These auxiliary rafters 71A to 76A are the same as the auxiliary rafters 71 and 72 in the first embodiment described above.

[0047] In this embodiment, the multi-window window 8A can be supported by rafters 61A to 64A which have greater strength than the other rafters 66A that do not support the multi-window window 8A, and therefore can be placed anywhere on the sloped roof 2. This allows the multi-window window 8A to be placed in accordance with the layout of the house 1A, thereby expanding the range of possible layouts for the house 1A.

[0048] In the above embodiments 1 and 2, it was explained that a series of windows 8, 8A are provided between the eaves beam 4 and the lowest main building 51, but it is also possible to provide only one skylight, or to provide multiple skylights at intervals (by positioning multiple rafters).

[0049] In the first and second embodiments, the strength of the rafters 6, 6A is increased by assembling multiple rafters or by providing reinforcing plates, but this is not a limitation. For example, to increase the strength of the rafters 6, they may be made of a stronger material other than wood, or the wood may be coated with resin. Any configuration that increases strength is possible. Furthermore, while the second rafters 62, 62A and the third rafter 63A are formed as a group of multiple rafters and provided with reinforcing plates, the strength of either one may be increased.

[0050] The above-described embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments, but should be defined by the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included. [Explanation of symbols]
