The upper frame member 9A, the lower frame member 9B, the left frame member 9C, and the right frame member 9D each have a long rectangular plate shape, for example, formed of wood or resin. The upper frame member 9A, the lower frame member 9B, the left frame member 9C, and the right frame member 9D are framed in a rectangle. Incidentally, the upper frame member 9A, the lower frame member 9B, the left frame member 9C, and the right frame member 9D may be collectively referred to as the "frame 9".

[0016] The joinery 10 is a device for opening and closing the opening 1a of the building H. The joinery 10, for example, forms a vertical sliding window together with the opening 1a. The joinery 10, for example, forms a window for ventilation, and more specifically, a ventilation window. The joinery 10 is installed, for example, on the exterior side of the opening 1a, and more specifically, on the exterior side of the frame 9. In this specification, "ventilation" means passing air between the interior and exterior sides, and means at least one of passing air from the exterior side to the interior side, or passing air from the interior side to the exterior side. "Ventilation window" means a window for taking in wind from the outside of the building into the interior of the building.

[0017] In this specification, "visible direction" means the direction in which the surface of the facing material of the sash 31, 51 in the closed state of the joinery 10 fitted into the opening 1a extends. "Left-right direction" is the horizontal direction in the visible direction, and means the left-right direction when the joinery 10 is viewed from the interior side. "Depth direction" means the thickness direction (i.e., depth direction) of the facing material 61 of the sash 31, 51 in the closed state. The "depth direction" is also the interior-exterior direction.

[0018] The joinery 10 comprises a frame 11, a first sliding screen 31, and a second sliding screen 51. The first sliding screen 31 and the second sliding screen 51 are sometimes collectively referred to as "sliding screens 31 and 51."

[0019] (Frame) The frame 11 is provided on the inner circumference side of the opening 1a. The frame 11 is provided on the exterior side of the picture frame 9. The frame 11 is frame-shaped, and more specifically, it is rectangular in shape. The frame 11 has an upper frame 12A, a lower frame 12B, a left frame 12C, and a right frame 12D.

[0020] (Top frame) The upper frame 12A is provided along the upper edge of the opening 1a. The upper frame 12A is elongated and extends in the left-right direction. The upper frame 12A is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the upper frame 12A may be made of a metal such as aluminum. The upper frame 12A has an angle portion 13A and an upper frame body portion 15A.

[0021] The angle section 13A is provided on the outdoor side of the upper frame 9A. The angle section 13A extends from the indoor side to the outdoor side parallel to the depth direction and the left-right direction, and further extends upward parallel to the visibility direction. The outdoor end of the angle section 13A has a roughly L-shape when viewed in the left-right direction. The angle section 13A covers the outdoor side surface of the upper frame 9A and the outdoor end of the bottom surface of the frame 9 from the outdoor side. The outdoor end of the bottom surface of the upper frame 9A is cut out by the thickness of the angle section 13A. The bottom surface of the angle section 13A and the bottom surface of the upper frame 9A are roughly flush. The angle section 13A is fixed to the bottom surface of the upper frame 9A, for example, and more specifically, it is screwed in.

[0022] The upper frame body portion 15A includes an airtight material mounting portion 16A, a hollow portion 17A, a hollow portion 18A, an indoor extension portion 19A, a hollow portion 21A, a visible wall portion 22A, a hollow portion 23A, a visible wall portion 25A, and a hollow portion 26A.

[0023] The airtight seal mounting section 16A is provided at the lower and indoor-facing end of the upper frame body section 15A. An airtight seal 16Aa is provided on the outdoor-facing surface of the airtight seal mounting section 16A. The airtight seal 16Aa is made of, for example, ethylene propylene diene rubber.

[0024] The hollow section 17A is adjacent to the upper side of the airtight material mounting section 16A. The hollow section 17A faces the exterior side of the angle section 13A. The hollow section 17A has a roughly rectangular tubular shape that extends in the left-right direction.

[0025] The hollow section 18A is adjacent to the upper side of the hollow section 17A. The hollow section 18A faces the exterior side of the angle section 13A. The hollow section 17A is fixed to the angle section 13A, specifically by screws (not shown). This fixes the angle section 13A and the upper frame body section 15A. The hollow section 18A has a roughly rectangular tubular shape that extends in the left-right direction.

[0026] The interior extension portion 19A extends inward from the upper and interior end of the hollow portion 18A. The interior extension portion 19A extends inward from the hollow portion 18A in a direction approximately parallel to the horizontal, and further inward, it slopes upward. The interior end of the interior extension portion 19A is fixed to the upper beam portion 2A, specifically by screw fastening. In this way, the upper frame main body portion 15A is fixed to the exterior wall portion 1.

[0027] The hollow section 21A is adjacent to the outdoor side of the hollow section 18A. The upper surface of the hollow section 21 is substantially flush with the upper surface of the hollow section 18A. The hollow section 21A has a substantially rectangular tubular shape that extends in the left-right direction.

[0028] The visible wall portion 22A extends upward from the upper and exterior end of the hollow portion 21A. The visible wall portion 22A is a flat plate with its surface extending parallel to the visible direction. The visible wall portion 22A is aligned with the structural plywood 4 and the upper beam portion 2A in the depth direction. The visible wall portion 22A is fixed to the structural plywood 4 and the upper beam portion 2A, specifically by screws. In this way, the upper frame body portion 15A is fixed to the exterior wall portion 1.

[0029] Furthermore, waterproof tape T is applied from the exterior surface of the visible wall portion 22A to the exterior surface of the structural plywood 4. In addition, the breathable waterproof sheet 6 extends from the exterior surface of the visible wall portion 22A to the exterior surface of the structural plywood 4. The breathable waterproof sheet 6 is provided on the exterior side of the waterproof tape T. These measures enhance the watertightness and airtightness between the upper frame 12A and the opening 1a.

[0030] The hollow section 23A is adjacent to the outdoor side of the hollow section 21A. The upper surface of the hollow section 23A is substantially flush with the upper surface of the hollow section 21A. The hollow section 23A has a substantially rectangular tubular shape that extends in the left-right direction. However, when viewed in the left-right direction, the lower and outdoor end of the hollow section 23A is recessed toward the upper and indoor side.

[0031] The visible wall portion 25A extends downward from the outdoor end of the hollow portion 23A. The visible wall portion 25A has a flat plate shape with its surface extending parallel to the visible direction.

[0032] The hollow section 26A is adjacent to the outdoor side of the hollow section 23A. The upper surface of the hollow section 26A is substantially flush with the upper surface of the hollow section 23A. The hollow section 26A has a substantially rectangular tubular shape that extends in the left-right direction. The lower surface of the hollow section 26A slopes upward as it faces the outdoor side. The hollow section 26A tapers towards the outdoor side.

[0033] Furthermore, the gap between the frame 11 and the exterior wall material 8 is sealed all around with sealant S. A backup material B is provided all around the gap between the sealant S and the frame 11. For example, the gap between the upper frame 12A (specifically, the hollow portion 26A) and the exterior wall material 8 is sealed with sealant S. A backup material B is provided in the gap between the sealant S and the visible wall portion 22A of the upper frame 12A.

[0034] The sealant S is, for example, a modified silicone-based sealant. This improves the watertightness and airtightness between the joinery 10 and the exterior wall material 8. The backup material B is a tube with a roughly annular cross-section. The backup material B is made of, for example, foamed polyethylene. This forms the bottom of the joint into which the sealant S is filled, suppressing three-sided adhesion of the sealant S and allowing adjustment of the depth to which the sealant S is filled.

[0035] (Bottom frame) The lower frame 12B is provided along the lower edge of the opening 1a. The lower frame 12B is elongated and extends in the left-right direction. The lower frame 12B is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the lower frame 12B may be made of a metal such as aluminum.

[0036] The lower frame 12B is constructed to be roughly symmetrical with the upper frame 12A. For this reason, the explanation of the lower frame 12B will be omitted in principle, and the differences from other parts of the frame body 11 will be explained. The reference numerals of each component of the lower frame 12B are the same as the reference numerals of the corresponding components of the upper frame 12A. However, the reference numerals of each component of the lower frame 12B are prefixed with "B" instead of "A".

[0037] In the lower frame 12B, the angle portion 13B is fixed to the lower frame 9B, for example, and is more specifically screwed in. The lower frame main body portion 15B is fixed to the lower beam portion 2B, for example, and is more specifically screwed in. In this way, the lower frame 12B is fixed to the opening 1a.

[0038] (Left frame) The left frame 12C is provided along the left edge of the opening 1a. The left frame 12C is elongated and extends in the vertical direction. The left frame 12C is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the left frame 12C may be made of a metal such as aluminum.

[0039] The configuration of the left frame 12C largely corresponds to the configuration of the upper frame 12A rotated 90° to the left. Therefore, the explanation of the left frame 12C will be omitted in principle, and the differences from other parts of the frame body 11 will be explained. The symbols of each component of the left frame 12C are the same as the symbols of the corresponding components of the upper frame 12A. However, the letter "C" is added to the end of the symbols of each component of the left frame 12C instead of "A".

[0040] In the left frame 12C, the angle portion 13C is fixed to the left frame 9C, for example, and is more specifically screwed in. The left frame main body portion 15C is fixed to the left column portion 2C, for example, and is more specifically screwed in. In this way, the left frame 12C is fixed to the opening 1a.

[0041] (Right frame) The right frame 12D is provided along the right edge of the opening 1a. The right frame 12D is elongated and extends in the vertical direction. The right frame 12D is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the right frame 12D may be made of a metal such as aluminum.

[0042] The configuration of the right frame 12D roughly corresponds to the configuration of the upper frame 12A rotated 90° to the right. The right frame 12D is roughly symmetrical to the left frame 12C. For this reason, the explanation of the right frame 12D will be omitted in principle, and the differences from other parts of the frame body 11 will be explained. The symbols of each component of the right frame 12D are the same as the symbols of the corresponding components of the upper frame 12A. However, the symbols of each component of the right frame 12D are followed by "D" instead of "A".

[0043] In the right frame 12D, the angle portion 13D is fixed to the right frame 9D, for example, and is more specifically screwed in. The right frame main body portion 15D is fixed to the right column portion 2D, for example, and is more specifically screwed in. In this way, the right frame 12D is fixed to the opening 1a.

[0044] (First sliding door) The first sliding door 31 is installed inside the frame 11. The first sliding door 31 opens by rotating and sliding out.

[0064] The hollow portion 62A is adjacent to the lower side of the hollow portion 58A. The hollow portion 62A has a roughly rectangular tubular shape that extends in the left-right direction. The hollow portion 62A is formed separately from, for example, the portion of the second upper frame 53A excluding the hollow portion 62A. The hollow portion 62A and the portion of the second upper frame 53A excluding the hollow portion 62A are connected, for example, by engagement.

[0065] The surface material holding portion 63A is the part that holds the surface material 61. The surface material holding portion 63A is formed by being surrounded by hollow portion 55A, hollow portion 57A, and hollow portion 62A. The surface material holding portion 63A opens downwards and has a groove-like shape with the left-right direction as its longitudinal direction.

[0066] (1st lower stile) The first lower frame 33B is provided along the upper surface of the lower frame 12B. The first lower frame 33B has a long shape that extends in the left-right direction. The first lower frame 33B is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the first lower frame 33B may be made of a metal such as aluminum. The first lower frame 33B has a first lower frame body 34B and a second lower frame 53B.

[0067] The first lower frame 33B is constructed to be roughly vertically symmetrical with the first upper frame 33A. For this reason, a detailed explanation of the first upper frame 33A will be omitted in principle, and the differences between the first frame body 32 and other parts will be explained. The reference numerals of each component of the first lower frame 33B are the same as the reference numerals of the corresponding components of the first upper frame 33A. However, the reference numerals of each component of the first lower frame 33B are prefixed with "B" instead of "A".

[0068] (1st left stile) The first left frame 33C is provided along the right side of the left frame 12C. The first left frame 33C is elongated and extends in the vertical direction.

The first left frame 33C is the door frame of the first shoji screen 31.

[0069] The configuration of the first left frame 33C generally corresponds to the configuration of the first upper frame 33A rotated 90° to the left. For this reason, a detailed explanation of the first left frame 33C will be omitted in principle, and the differences from other parts of the first frame body 32 will be explained. The symbols of each component of the first left frame 33C are the same as the symbols of the corresponding components of the first upper frame 33A. However, the symbol of each component of the first left frame 33C is followed by "C" instead of "A".

[0070] (1st right stile) The first right frame 33D is provided along the left side of the right frame 12D. The first right frame 33D is elongated and extends in the vertical direction. The first right frame 33D is made of a profile obtained by extruding a resin such as polyvinyl chloride. However, it is not limited to this, and the first right frame 33D may be made of a metal such as aluminum. The first right frame 33D has a first right frame body 34D and a second right frame 53D.

[0071] The configuration of the first right frame 33D generally corresponds to the configuration of the first upper frame 33A rotated 90° to the right. The first right frame 33D is configured to be roughly symmetrical with the first left frame 33C. For this reason, the explanation of the first right frame 33D will be omitted in principle, and the differences from other parts of the first frame body 32 will be explained. The symbols of each component of the first right frame 33D are the same as the symbols of the corresponding components of the first upper frame 33A. However, the symbol of each component of the first right frame 33D is given a "D" instead of an "A".

[0072] Furthermore, the first frame 32 is constructed by combining a plurality of frame-shaped members. The first frame 32 has a first frame main body 34 and a second frame 52.

[0073] The first frame body portion 34 is frame-shaped, more specifically, rectangular. The first frame body portion 34 has a first upper frame body portion 34A, a first lower frame body portion 34B, a first left frame body portion 34C, and a first right frame body portion 34D. The first frame body portion 34 is formed by framing the first upper frame body portion 34A, the first lower frame body portion 34B, the first left frame body portion 34C, and the first right frame body portion 34D in a rectangular shape.

[0074] The second frame 52 is provided on the inner circumference side of the first frame body 34, and more specifically, it is provided on the inside and outside side of the first frame body 34. The second frame 52 is frame-shaped, and more specifically, it is rectangular. The second frame 52 has a second upper frame 53A, a second lower frame 53B, a second left frame 53C, and a second right frame 53D. The second frame 52 is formed by framing the above-mentioned second upper frame 53A, second lower frame 53B, second left frame 53C, and second right frame 53D in a rectangular shape.

[0075] (Surface material) The facing material 61 is provided on the inner circumference side of the first frame 32. The facing material 61 is provided on the inner circumference side of the second frame 52. The facing material 61 is located, for example, on the exterior side of the exterior wall 1. The facing material 61 is held in place by facing material holding parts 63A, 63B, 63C, and 63D (sometimes collectively referred to as "facing material holding parts 63"). The peripheral edge of the facing material 61 is inserted into the grooves of the facing material holding parts 63. A setting block 64 is placed between the facing material 61 and the bottom surface of the grooves of the facing material holding parts 63. The setting block 64 is made of, for example, resin.

[0076] The facing material 61 is a flat plate with a roughly rectangular shape. The facing material 61 is installed with its surface oriented so that it is roughly parallel to the vertical and horizontal directions. The facing material 61 is, for example, a glass panel, and more specifically, a double-glazed glass panel.

[0077] (Second sliding door) The second sliding door 51 is provided on the inner circumference side of the first frame body 34. The second sliding door 51 opens by rotating and sliding outwards. The second sliding door 51 is, for example, a vertical sliding type sliding door. The second sliding door 51 opens by sliding outwards toward the outside, for example. The second sliding door 51 is, for example, a right-opening sliding door. When the second sliding door 51 is open, its rotation direction is counterclockwise in a plan view from above. The second sliding door 51 has a second frame body 52 and a facing material 61. The second right frame 53D is the door edge frame of the second sliding door 51.

[0078] The second frame 52 and the facing material 61 are part of the components of the first sliding door 31. The second sliding door 51 constitutes a part of the first sliding door 31.

[0079] The direction of rotation when the first sliding door 31 is open and the direction of rotation when the second sliding door 51 is open are different directions; more specifically, they are opposite directions.

[0080] The second frame 52 constitutes a part of the first frame 32; more specifically, the entire second frame 52 constitutes a part of the first frame 32. The portion of the first frame 32 excluding the second frame 52 (i.e., the main body of the first frame 34) functions as a frame for the second shoji screen 51. The second frame 52 functions as a surface material holding part for the first frame 32.

[0081] The second frame 52 and the first frame body 34 overlap, for example, in the depth direction. This makes it easier to fit the second sliding door 51 into the first sliding door 31 when the second sliding door 51 is closed. It also makes it easier to improve the airtightness and watertightness between the second frame 52 and the first frame body 34. Therefore, the first frame body 34 can function suitably as a frame for the second sliding door 51.

[0082] The portion of the second frame 52 that overlaps with the first frame body 34 in the depth direction is formed, for example, over the entire circumferential area of ​​the second frame 52. This allows the first frame body 34 to function more effectively as a frame for the second sliding door 51.

[0083] The facing material 61 that constitutes the first shoji screen 31 is made up of the facing material 61 that constitutes the second shoji screen. The first shoji screen 31 and the second shoji screen 51 share one facing material 61. The facing material 61 is a facing material that constitutes both the first shoji screen 31 and the second shoji screen 51.

[0084] Furthermore, the joinery 10 includes a first stay 65 and a second stay 66.

[0085] The first stay 65, as will be described in more detail later, is a member that supports the opening and closing operation of the first sliding door 31 relative to the frame 11. The first stay 65 connects the first sliding door 31 and the frame 11. The first stay 65 has an upper first stay 65A and a lower first stay 65B.

[0086] The upper first stay 65A is provided on the upper part of the door 10. The upper first stay 65A connects the upper frame 12A and the first upper frame 33A, and more specifically, connects the hollow part 21A of the upper frame 12A and the hollow part 41A of the main body part 34A of the first upper frame.

[0087] The lower first stay 65B is provided at the bottom of the door 10. The lower first stay 65B connects the lower frame 12B and the first lower stile 33B, and more specifically, connects the hollow portion 21B of the lower frame 12B and the hollow portion 41B of the main body portion 34B of the first lower stile.

[0088] The second stay 66, as will be described in more detail later, is a member that supports the opening and closing operation of the second sliding door 51 relative to the first sliding door 31. The second stay 66 connects the second sliding door 51 to the first frame body 34. The second stay 66 has an upper second stay 66A and a lower second stay 66B.

[0089] The upper second stay 66A is provided on the upper part of the door 10. The upper second stay 66A connects the first upper frame main body 34A and the second upper frame 53A, and more specifically, connects the hollow part 43A of the first upper frame main body 34A and the hollow part 57A of the second upper frame 53A.

[0090] The lower second stay 66B is provided at the bottom of the door / window 10. The lower second stay 66B connects the first bottom frame main body 34B and the second bottom frame 53B, and more specifically, connects the hollow portion 43B of the first bottom frame main body 34B and the hollow portion 57B of the second bottom frame 53B.

[0091] Furthermore, the door / window 10 includes a first operating part 71, a first latch part 72, a first latch receiving part 73, a second operating part 75, a second latch part 76, and a second latch receiving part 77.

[0092] The first operating part 71 is a part operated by the user when opening and closing the first sliding door 31. The first operating part 71 is, for example, a lever handle. The first operating part 71 is provided, for example, on the first left frame 33C, and more specifically, on the right side of the hollow portion 35C of the first left frame main body 34C.

[0093] The first latch portion 72 is provided, for example, on the first left frame 33C, and more specifically, on the portion of the first left frame main body 34C enclosed by the hollow portion 35C, the visible wall portion 36C, and the hollow portion 41C. The first latch portion 72 protrudes to the left from the first left frame main body 34C.

[0094] The first latch receiving portion 73 is the portion that engages with the first latch portion 72. The first latch receiving portion 73 is provided, for example, on the left frame 12C, and more specifically, on the hollow portion 21C of the left frame 12C. The first latch receiving portion 73 protrudes to the right from the left frame 12C. The first latch portion 72 and the first latch receiving portion 73 are detachably engaged. When the first sliding door 31 is in the closed state, the first latch portion 72 and the first latch receiving portion 73 are engaged.

[0095] The second operating section 75 is a part operated by the user when opening and closing the second sliding door 51. The second operating section 75 is, for example, a lever handle. The second operating section 75 is provided, for example, on the second right frame 53D, and more specifically, on the left side of the hollow section 55D.

[0096] The second latch portion 76 is provided, for example, on the second right frame 53D, and more specifically, in the portion enclosed by the hollow portion 55D, the visible wall portion 56D, and the hollow portion 57D. The second latch portion 76 protrudes to the right from the second right frame 53D.

[0097] The second latch receiving portion 77 is the part that engages with the second latch portion 76. For example, it is provided on the first right frame 33D, and more specifically, on the hollow portion 57D of the first right frame main body 34D. The second latch receiving portion 77 protrudes to the left from the first upper frame main body 34A. The second latch portion 76 and the second latch receiving portion 77 are detachably engaged. When the second sliding door 51 is closed relative to the first sliding door 31, the second latch portion 76 and the second latch receiving portion 77 are engaged.

[0098] Next, the opening and closing of the door 10 will be explained with reference to Figures 4 to 6. Note that in Figures 4 to 6, some parts of the opening and closing mechanism of the door 10 are omitted from the illustration.

[0099] When opening the first sliding door 31, the first operating part 71 is operated. When the first operating part 71 is moved toward the outside, the engagement between the first latch part 72 and the first latch receiving part 73 is released. Next, the arm of the upper first stay 65A and the arm of the lower first stay 65B extend, and the first sliding door 31 moves toward the outside while rotating on a rotation axis that extends vertically, for example. The first sliding door 31 rotates clockwise when viewed from above, for example, around the tail end side (first right frame 33D side) of the first sliding door 31. As a result, the first sliding door 31 is opened, as shown in Figure 4. By opening the first sliding door 31, it is possible to easily draw in wind blowing from the left side of the first sliding door 31 into the room.

[0100] When opening the second sliding door 51, the second operating part 75 is operated. When the second operating part 75 is moved toward the outside, the engagement between the second latch part 76 and the second latch receiving part 77 is released. Next, the arms of the upper second stay 66A and the lower second stay 66B extend, and the second sliding door 51 moves toward the outside while rotating around a rotation axis that extends in the vertical direction. The second sliding door 51 rotates counterclockwise when viewed from above, for example, around the tail end side (second left frame 53C side) of the second sliding door 51. As a result, the second sliding door 51 is opened, as shown in Figure 5. By opening the second sliding door 51, it is possible to easily draw in wind blowing from the right side of the second sliding door 51 into the room.

[0101] Furthermore, the first shoji screen 31 and the second shoji screen 51 can be opened and closed independently of each other's open / closed state. As shown in Figure 6, the first shoji screen 31 and the second shoji screen 51 can be opened simultaneously. This makes it easier to bring wind from various directions into the room.

[0102] Furthermore, the leading edge of the second shoji screen 51 (specifically, the right end of the second right frame 53D) and the leading edge of the first shoji screen 31 (specifically, the left end of the first left frame 33C) are located on opposite sides of the center of the opening 1a in the visible direction. This makes it easier to draw in the wind blowing towards the trailing edge of the first shoji screen 31 into the room by opening the second shoji screen 51 when the first shoji screen 31 is opened.

[0103] Furthermore, the first sliding door 31 can be opened until, for example, the angle between the surface of the facing material 61 and the exterior surface of the exterior wall 1 is approximately 90°. When the first sliding door 31 is fully open, the frame on the door-end side of the first sliding door 31 (first right frame 33D) overlaps, for example, the center of the opening 1a in the left-right direction with the depth direction. When the first sliding door 31 is fully open, the part of the opening 1a to the left of the first sliding door 31 and the part of the opening 1a to the right of the first sliding door 31 are connected to the inside and outside, respectively. Therefore, whether the wind is blowing from the left side of the first sliding door 31 or from the left side of the first sliding door 31, wind can be drawn into the room through the opening 1a.

[0104] The second sliding door 51 can be opened, for example, until the angle between the surface of the facing material 61 and the exterior surface of the exterior wall 1 is approximately 90°. When the second sliding door 51 is fully open, the door frame on the tail end side of the second sliding door 51 (second left frame 53C) overlaps, for example, with the center of the opening 1a in the left-right direction and in the depth direction. When the second sliding door 51 is fully open, the part of the opening 1a to the left of the second sliding door 51 and the part of the opening 1a to the right of the second sliding door 51 are connected to the inside and outside, respectively. Therefore, whether the wind is blowing from the left side of the second sliding door 51 or from the left side of the second sliding door 51, wind can be drawn into the room through the opening 1a.

[0105] <Effects according to the first embodiment> The following effects are achieved with the building fixture 10 of this embodiment.

[0106] The joinery 10 comprises a frame 11, a first sliding door 31 that rotates and slides out to open, and a second sliding door 51 that rotates and slides out to open. The second sliding door 51 forms a part of the first sliding door 31, and the direction of rotation of the first sliding door 31 when it is open and the direction of rotation of the second sliding door 51 when it is open are different.

[0107] With this configuration, for example, by opening the first shoji screen 31, wind blowing from one side in the left-right direction can be efficiently drawn into the room. By opening the second shoji screen 51, wind blowing from the other side in the left-right direction can be efficiently drawn into the room. As a result, by selecting which shoji screen to open according to the wind direction, wind can be efficiently drawn into the room. Therefore, it is possible to provide a building fixture with excellent ventilation efficiency.

[0108] Furthermore, since the door 10 can be opened and closed in multiple directions, the constraints on the interior design caused by the placement of the door 10 can be alleviated.

[0109] The first sliding door 31 has a first frame 32, and the second sliding door 51 has a second frame 52, the second frame 52 forming a part of the first frame 32.

[0110] With this configuration, the second shoji screen 51 can be easily enlarged, thereby more effectively suppressing the decrease in ventilation efficiency due to wind direction.

[0111] Furthermore, by using the portion of the first frame 32 excluding the second frame 52 (the main body portion of the first frame 34) as the frame for the second sliding door 51, the fit of the second sliding door 51 to the first sliding door 31 can be improved.

[0112] The facing material 61 that constitutes the first shoji screen 31 is made up of the facing material 61 that constitutes the second shoji screen 51.

[0113] With this configuration, the structure can be simplified by using one panel 61 for both the first shoji screen 31 and the second shoji screen 51.

[0114] The joinery 10 constitutes a vertical sliding window, with the first sash 31 being either a right-opening sash or a left-opening sash (specifically, a left-opening sash), and the second sash 51 being either a right-opening sash or a left-opening sash (specifically, a right-opening sash).

[0115] With this configuration, ventilation efficiency can be improved in a vertical sliding window.

[0116] The joinery 10 constitutes a ventilation window.

[0117] Ventilation windows are installed in buildings with the purpose of bringing air from the outside into the building. However, the wind direction is not constant outside the building. Depending on the wind direction and the direction in which the shoji screen is opened, the wind may be blocked by the shoji screen, potentially hindering the intake of air through the ventilation window. With this configuration, the joinery 10 can take in wind blowing from various directions into the room by selecting which shoji screens 31 and 51 to open according to the wind direction. For this reason, the joinery 10 can be suitably used as a ventilation window.

[0118] <Second Embodiment> Next, a second embodiment of this disclosure will be described with reference to Figures 7 to 10. The explanation will focus on the differences from the first embodiment. Components similar to those in the first embodiment may be denoted by the same reference numerals and their description may be omitted.

[0119] In the second embodiment of the joinery 110, the first sliding door 31 and the second sliding door 51 are opened and closed automatically. As shown in Figures 7 to 10, the joinery 110 includes an electric unit 111 that automatically opens and closes the sliding doors 31 and 51.

[0120] In the second embodiment, the lower frame 12B is provided with an auxiliary frame 181. The auxiliary frame 181 is a member to which the electric unit 111 is attached. The auxiliary frame 181 has a long shape that extends in the left-right direction. The auxiliary frame 181 is made of a profile obtained by extruding a metal such as aluminum, for example. The auxiliary frame 181 has a lower extension portion 182, a hollow portion 185, an engaging portion 186, a hollow portion 187, and a hollow portion 188.

[0121] The lower extension 182 is provided at the lower end of the auxiliary frame 181. The lower extension 182 is located between the hollow portion 18B of the lower frame 12B and the lower frame 9B. The lower extension 182 has an elongated shape with its longitudinal direction running horizontally. The lower extension 182 extends vertically. Backing materials 183 are provided on both the outdoor and indoor sides of the lower extension 182. The lower extension 182, together with each of the backing materials 183, is sandwiched between the lower frame 12B and the lower frame 9B. This suppresses rattling of the auxiliary frame 181.

[0122] The hollow section 185 is adjacent to the upper side of the lower extension 182. The hollow section 185 faces the hollow section 17B and the airtight material mounting section 16B of the lower frame 12B in the depth direction. The interior end of the hollow section 185 is located further inward than the interior end of the lower extension 182. The hollow section 185 faces the lower frame 9B at a vertical distance. The hollow section 185 has a polygonal cylindrical shape extending in the left-right direction. The hollow section 185 is fixed to the lower frame 12B, and more specifically, it is screwed to the airtight material mounting section 16B. In this way, the auxiliary frame 181 is fixed to the lower frame 12B.

[0123] The engaging portion 186 extends outward from the upper and exterior end of the hollow portion 185. The engaging portion 186 extends outward from the hollow portion 185 and further downward. In addition, a projection 16Bb is provided at the upper and interior end of the airtight material mounting portion 16B of the lower frame 12B, projecting upward. The projection 16Bb and the engaging portion 186 are engaged. As a result, the auxiliary frame 181 is fixed to the lower frame 12B.

[0124] The hollow section 187 is adjacent to the upper side of the hollow section 185. The interior-facing surface of the hollow section 187 is substantially flush with the interior-facing surface of the hollow section 185. The hollow section 187 has a substantially rectangular tubular shape that extends in the left-right direction. When viewed in the left-right direction, the shape of the hollow section 187 is substantially rectangular with the vertical direction as its longitudinal direction. The depth dimension of the hollow section 187 is smaller than the depth dimension of the hollow section 185.

[0125] The hollow section 188 is adjacent to the upper side of the hollow section 187. The interior-facing surface of the hollow section 188 is substantially flush with the interior-facing surface of the hollow section 187. The hollow section 188 has a substantially rectangular tubular shape that extends in the left-right direction. When viewed in the left-right direction, the shape of the hollow section 188 is substantially rectangular with the depth direction as the longitudinal direction. The depth dimension of the hollow section 188 is larger than the depth dimension of the hollow section 187.

[0126] Furthermore, the portion of the auxiliary frame 181 consisting of hollow section 185, hollow section 187, and hollow section 188 has a roughly U-shape that opens toward the outside.

[0127] The electric unit 111 is provided, for example, on the frame 11. The electric unit 111 is attached, for example, to the auxiliary frame 181, or in other words, to the lower frame 12B via the auxiliary frame 181. The electric unit 111 includes a motor housing 112, a power transmission unit 113, and an arm 117.

[0128] The motor housing 112 houses a motor (not shown) that serves as the power source for the electric unit 111. The motor housing 112 is adjacent to the interior side of the auxiliary frame 181.

[0129] The power transmission unit 113 includes a transmission mechanism 115 and a case 116.

[0130] The transmission mechanism 115 connects the motor in the motor housing 112 to the arm 117. The transmission mechanism 115 converts the rotational motion of the motor into horizontal motion and transmits it to the arm 117. The transmission mechanism 115 is installed in the space enclosed by the hollow sections 185, 187, and 188 of the auxiliary frame 181.

[0131] Case 116 houses the transmission mechanism 115. Case 116 is adjacent to the outdoor side of the motor housing 112. Case 116 and the motor housing 112 are connected and, more precisely, are formed as a single unit. Case 116 is attached to the hollow sections 185, 187, and 188 of the auxiliary frame 181. Case 116 covers the transmission mechanism 115 and the hollow sections 185, 187, and 188 of the auxiliary frame 181.

[0132] The arm 117 extends from the transmission mechanism 115 toward the outside. The arm 117 is connected to the sliding doors 31 and 51 that are to be opened and closed. The arm 117 opens and closes the sliding doors 31 and 51 using the driving force of the motor.

[0133] The electric unit 111 includes a first electric unit 111A that automatically opens and closes the first sliding door 31, and a second electric unit 111B that automatically opens and closes the second sliding door 51. The configuration of the first electric unit 111A and the configuration of the second electric unit 111B correspond, for example. The components of the first electric unit 111A are denoted by "A" at the end of their symbols, and the components of the second electric unit 111B are denoted by "B" at the end of their symbols. However, the configurations of the first electric unit 111A and the second electric unit 111B are not particularly limited and can be changed.

[0134] In the joinery 110, the position in which the electric unit 111 is installed is not particularly limited. For example, the electric unit 111 may be placed near the upper frame 12A, or near the left frame 12C or the right frame 12D. The auxiliary frame 181 is not a mandatory component. The arm 117A of the first electric unit 111A may be connected to the first frame 32 or to the first stay 65. The arm 117B of the second electric unit 111B may be connected to the second frame 52 or to the second stay 66.

[0135] The second embodiment of the joinery 110 includes a screen door 191.

[0136] The screen door 191 is, for example, a fixed screen door. The screen door 191 is installed on the inner circumference side of the frame 11. The screen door 191 is installed on the interior side of the first sliding door 31 and the second sliding door 51. The screen door 191 has a mesh part 192, an attachment 193, and a screen door frame 159.

[0137] The mesh portion 192 is roughly rectangular in shape.

[0138] The attachment 193 has a rectangular frame shape. The attachment 193 is attached to the periphery of the mesh portion 192.

[0139] The screen door frame 159 is provided along the inner periphery of the frame 11. The screen door frame 159 has an upper screen door frame 196A extending along the upper frame 12A, a lower screen door frame 196B extending along the lower frame 12B, a left screen door frame 196C extending along the left frame 12C, and a right screen door frame 196D extending along the right frame. The screen door frame 159 is constructed by framing the upper screen door frame 196A, the lower screen door frame 196B, the left screen door frame 196C, and the right screen door frame 196D in a rectangular shape.

[0140] The screen door upper frame 196A is adjacent to the lower side of the airtight seal mounting portion 16A of the upper frame 12A. An airtight seal 196Aa is provided on the lower surface of the airtight seal mounting portion 16A. The airtight seal 196Aa is interposed between the screen door upper frame 196A and the airtight seal mounting portion 16A. The airtight seal 196Aa is a long rectangular plate with its longitudinal direction running horizontally. The airtight seal 196Aa is made of, for example, ethylene propylene diene rubber. This enhances the airtightness between the screen door upper frame 196A and the upper frame 12A. The screen door upper frame 196A has a roughly U-shape that opens downwards when viewed horizontally. The upper edge of the attachment 193 is inserted into the screen door upper frame 196A. As a result, attachment 193 is fixed to the screen door upper frame 196A.

[0141] The bottom frame 196B of the screen door is adjacent to the exterior side of the auxiliary frame 181. The bottom frame 196B of the screen door has a retaining portion 197B and an extension portion 198B.

[0142] The retaining portion 197B is adjacent to the exterior side of the hollow portion 188 of the auxiliary frame 181. When viewed from left to right, the retaining portion 197B has a roughly U-shape that opens upwards. The lower edge of the attachment 193 is inserted into the retaining portion 197B. In this way, the attachment 193 is fixed to the bottom frame 196B of the screen door (more specifically, the retaining portion 197B).

[0143] The extension portion 198B extends inward from the lower and interior end of the retaining portion 197B, and further extends downward. The extension portion 198B extends along the lower surface of the hollow portion 188 of the auxiliary frame 181, and further extends along the exterior surface of the hollow portion 187. The extension portion 198B fits into the space enclosed by, for example, the hollow portions 185, 187, and 188 of the auxiliary frame 181. As a result, the bottom frame 196B of the screen door is fixed to the auxiliary frame 181. The bottom frame 196B of the screen door is fixed to the bottom frame 12B via the auxiliary frame 181.

[0144] Furthermore, a portion of the case 116 of the electric unit 111 is adjacent to the interior side of the retaining portion 197B, and another portion of the case 116 is located inside the hollow portion 188 of the auxiliary frame 181. The bottom frame of the screen door 196B (more specifically, the extension portion 198B) and the auxiliary frame 181 are also fixed by the electric unit 111.

[0145] The left frame 196C of the screen door is adjacent to the right side of the airtight seal mounting portion 16C of the left frame 12C. An airtight seal 196Ca is provided on the right side of the airtight seal mounting portion 16C. The airtight seal 196Ca is interposed between the left frame 196C of the screen door and the airtight seal mounting portion 16C. The airtight seal 196Ca is a long rectangular plate with its longitudinal direction in the vertical direction. The airtight seal 196Ca is made of, for example, ethylene propylene diene rubber. This enhances the airtightness between the left frame 196C of the screen door and the left frame 12C. The left frame 196C of the screen door has a roughly U-shape that opens to the right when viewed in the vertical direction. The left edge of the attachment 193 is inserted into the left frame 196C of the screen door. This fixes the attachment 193 to the left frame 196C of the screen door.

[0146] The right frame 196D of the screen door is adjacent to the left side of the airtight seal mounting portion 16D of the right frame 12D. An airtight seal 196Da is provided on the left side of the airtight seal mounting portion 16D. The airtight seal 196Da is interposed between the right frame 196D of the screen door and the airtight seal mounting portion 16D. The airtight seal 196Da is a long rectangular plate with its longitudinal direction in the vertical direction. The airtight seal 196Da is made of, for example, ethylene propylene diene rubber. This enhances the airtightness between the right frame 196D of the screen door and the right frame 12D. The right frame 196D of the screen door has a roughly U-shape that opens to the left when viewed in the vertical direction. The right edge of the attachment 193 is inserted into the right frame 196D of the screen door. As a result, attachment 193 is fixed to the right frame 196D of the screen door.

[0147] Furthermore, the airtight material 196Aa, the airtight material 196Ca, and the airtight material 196Da may be formed as a single unit or as separate components.

[0148] In the first embodiment of the joinery 10, if a screen door is installed on the interior side of the first sliding door 31, the first operating part 71 and the second operating part 75 may interfere with the screen door. However, in the second embodiment of the joinery 110, the first sliding door 31 and the second sliding door 51 are opened and closed automatically. Therefore, the joinery 10 does not need to provide the first sliding door 31 and the second sliding door 51 with a configuration for manual operation (for example, a lever handle). As a result, in the second embodiment of the joinery 110, the configuration for manual operation of the first sliding door 31 and the second sliding door 51 can be omitted, making it easier to place a screen door 191 on the interior side of the first sliding door 31 and the second sliding door 51.

[0149] It is not forbidden that the first sliding door 31 and the second sliding door 51 be further provided with a configuration for manual operation in the joinery 110 of the second embodiment.

[0150] In the first embodiment of the joinery 10, if a screen door 191 is installed on the interior side of the first sliding door 31, it is considered troublesome to open and close or remove the screen door 191 in order to open and close the first sliding door 31 or the second sliding door 51. However, according to the second embodiment of the joinery 110, since the first sliding door 31 and the second sliding door 51 open and close automatically, it is possible to ensure the operability of the first sliding door 31 and the second sliding door 51 even in a configuration in which the screen door 191 is placed on the interior side of the first sliding door 31 and the second sliding door 51. In addition, it is possible to use a fixed screen door as the screen door 191.

[0151] <Third Embodiment> Next, a third embodiment of this disclosure will be described with reference to Figures 11 to 20. In the third embodiment, the joinery 110 of the second embodiment is controlled by the joinery control device 310 in the joinery control system 300. Note that components similar to those in the above embodiments may be denoted by the same reference numerals and their description may be omitted.

[0152] (Overall system configuration) The door and window control system 300 in Figure 11 includes a building H and a multi-sensor 320. Building H may be any building such as a house or office building. The multi-sensor 320, which is associated with building H, is installed outside building H. A door and window control device 310, which is associated with building H, is installed either inside or outside building H. The door and window control device 310 receives data from the multi-sensor 320 installed outside building H. Based on this data, the door and window control device 310 controls electric equipment such as a window opening and closing device installed in a window D. This electric equipment may include not only ventilation equipment for exchanging indoor and outdoor air, but also air conditioning equipment for adjusting indoor temperature and humidity, etc. The door and window control device 310 can control all electric opening and closing devices installed in openings such as windows, casement windows, sliding windows, doors, casement windows built into doors, and sliding doors. As shown in Figure 12, the multi-sensor 320 is a sensor capable of acquiring at least one spot weather data (also referred to as environmental information) from among temperature, humidity, illuminance, rainfall, wind speed, and wind direction at the location where it is installed (also referred to as a spot). The multi-sensor 320 may further acquire dust levels such as PM2.5 / yellow dust, pollen, and house dust, noise levels, and odors (e.g., unusual odors). The multi-sensor 320 may also be equipped with a camera function. The multi-sensor 320 may be a single multi-sensor or may be composed of multiple sensors. The multi-sensor 320 is connected to the corresponding building device control device 310 wirelessly or via a wired connection.

[0153] (Device configuration) As shown in Figure 11, the door and window control device 310 includes a CPU (Central Processing Unit) 311, a communication unit 317, and a storage unit 318. The CPU 311 performs various functions by operating according to a pre-prepared program. Specifically, the CPU 311 has the functions of a ventilation determination unit 312, a wind data acquisition unit 313, an open door and window determination unit 314, and an open / close instruction unit 315. These functions will be described later.

[0154] The communication unit 317 is an interface for connecting to a wide-area communication network such as the Internet. The door and window control device 310 can communicate with external devices such as servers via the wide-area communication network and the communication unit 317.

[0155] The memory unit 318 is a so-called auxiliary storage device, a non-volatile storage area such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). The memory unit 318 also stores a pre-constructed prediction model, which may be configured to be updatable by machine learning using a learning device. The prediction model is constructed using an algorithm that learns the model's parameters to optimize performance metrics, such as those found in a neural network.

[0156] (Example of operation) Referring to Figure 13, the processing flow executed by the door and window control device 310 will be explained.

[0157] The ventilation determination unit 312 of the door and window control device 310 decides to perform ventilation on building H (step S101). The decision to perform ventilation may be made remotely by a terminal such as a smartphone owned by the occupant of building H, or by an operation by the occupant on a display device installed in building H. Alternatively, the decision to perform ventilation may be made automatically based on the value obtained by at least one of the temperature and humidity sensors, dust level sensors, and odor sensors installed in building H indicating a value that recommends ventilation.

[0158] The multi-sensor 320 acquires spot weather data at the installation location. The multi-sensor 320 transmits the acquired spot weather data to the building fixture control device 310 (step S102).

[0159] The door and window control device 310 determines whether the wind speed value shown in the spot weather data is above a predetermined threshold. Based on this determination, the door and window control device 310 determines whether there is wind speed or not (step S103). If it is determined that the wind speed value is below the predetermined threshold (for example, less than 0.2 m / s) (step S103: no), it means that the wind strength around building H is too weak, and opening the door and window is not effective for ventilation. Therefore, in this case, the opening / closing instruction unit 315 instructs the door and window to close (step S104). This avoids inefficient window opening because it is not possible to take in outside air when the wind is too weak. If it is determined that the wind speed value is above the predetermined threshold (for example, 0.2 m / s or more) (step S103: yes), the wind data acquisition unit 313 acquires wind direction data shown in the spot weather data (step S105). Furthermore, if the wind speed reaches a dangerous level (for example, 5.0 m / s or higher), opening the doors and windows may be stopped to avoid damage to them.

[0160] Next, the openable door / window determination unit 314 determines whether or not there is a door / window to be opened based on the acquired wind direction data (step S106). Specifically, it determines whether or not there is a door / window to be opened corresponding to the wind direction data based on a table that associates door / window identifiers of doors / windows in building H with the set wind direction, as shown in Figure 16. The operation of step S106 will be further explained below with a specific example. Note that the doors / windows in building H may be any windows that can be opened. For example, the doors / windows may be windows, casement windows, sliding windows, doors, casement windows built into doors, sliding doors, etc.

[0161] As shown in Figures 14 and 15, building H includes window D1 and window D2. Each window has an opening surface and an opening surface direction. The opening surface means the opening of the window when it is fully open, that is, the surface on which the window captures wind when it is fully open. The opening surface direction means the direction perpendicular to the opening surface when the window is fully open, that is, the direction in which the window can capture the most wind.

[0162] Window D1 is located on the eastern exterior wall of building H. Window D1 is a sliding window, specifically a vertical sliding window. Window D1 is the joinery 110 of the second embodiment. Window D1 is sometimes referred to as "joinery 110". Joinery 110 comprises a first sash 31, a second sash 51, and an electric unit 111.

[0163] Furthermore, the joinery controlled by the joinery control device 310 can also be configured on a per-component basis (for example, a sliding door). The first sliding door 31 and the second sliding door 51 correspond to joinery controlled by the joinery control device 310, respectively.

[0164] A joinery identifier can also be assigned to a component of a joinery. The first sliding door 31 and the second sliding door 51 are each assigned different joinery identifiers. The joinery identifier assigned to the first sliding door 31 is denoted as "Joinery Identifier D1a," and the joinery identifier assigned to the second sliding door 51 is denoted as "Joinery Identifier D1b."

[0165] The electric unit 111 electrically opens the sliding doors 31 and 51. The electric unit 111 has a first electric unit 111A and a second electric unit 111B. The first electric unit 111A automatically opens, or more specifically, opens and closes, only the first sliding door 31 of the sliding doors 31 and 51. The second electric unit 111B automatically opens, or more specifically, opens and closes, only the second sliding door 51 of the sliding doors 31 and 51. The first electric unit 111A and the second electric unit 111B are each electrically connected to the door control device 310. The first electric unit 111A and the second electric unit 111B each correspond to electric equipment for opening the target door. The first electric unit 111A corresponds to the first electric equipment, and the second electric unit 111B corresponds to the second electric equipment.

[0166] The first shoji screen 31 opens by sliding outwards toward the exterior (see Figure 14). The first shoji screen 31 is a right-opening screen. The direction of the opening surface of the first shoji screen 31 is north-northeast. That is, the wind that the first shoji screen 31 can capture most effectively is wind coming from the north-northeast toward building H (i.e., north-northeast wind). The first shoji screen 31 can also effectively capture wind coming from the north toward building H (i.e., north wind). Therefore, as shown in Figure 16, the joinery identifier D1a is stored in the table associated with north to north-northeast.

[0167] The second shoji screen 51 opens by sliding outwards toward the exterior (see Figure 15). The second shoji screen 51 is a left-opening screen. The direction of the opening surface of the second shoji screen 51 is south-southeast. That is, the wind that the second shoji screen 51 can capture most effectively is wind coming from the south-southeast toward building H (i.e., south-southeast wind). The second shoji screen 51 can also effectively capture wind coming from the south toward building H (i.e., south wind). Therefore, as shown in Figure 16, the joinery identifier D1b is stored in the table associated with south to south-southeast.

[0168] Window D2 is located on the western exterior wall of building H. Window D2 is, for example, a sliding window. Window D2 is assigned a joinery identifier. Let's call the joinery identifier for window D2 "Joinery Identifier D2".

[0169] The opening of window D2 faces west. Therefore, window D2 can best capture winds that travel from the west towards building H (i.e., westerly winds). Consequently, as shown in Figure 16, the door / window identifier D2 is associated with west and stored in the table.

[0170] The set airflow direction on the table may be initially set based on the position of the door / window relative to building H and the direction in which the door / window opens when the door / window control device 310 is installed in building H. Alternatively, the set airflow direction on the table may be changed as appropriate by the residents of building H. Alternatively, the set airflow direction on the table may be modified as appropriate by machine learning based on actually acquired airflow direction data and ventilation results.

[0171] Figure 17 shows a north wind W2 blowing. That is, the wind direction acquired in step S105 is north. Here, the acquired wind direction corresponds to the set wind direction "North to North-Northeast" for the door / window identifier "D1a" among the set wind directions stored in the table in Figure 16. At this time, it is determined that there is a door / window to be opened (step S106: Yes). The door / window to be opened determination unit 314 determines that the door / window to be opened is the first sash 31 of window D1. Subsequently, the opening / closing instruction unit 315 sends an opening instruction to the electric equipment that controls the opening and closing of the first sash 31 (i.e., the first electric unit 111A) in order to open the first sash 31, causing window D2 to open (step S107). The second sash 51 of window D1 and window D2 may remain closed as shown in Figure 17. If the second sash 51 and window D2 are in an open state, they may be controlled to close. Alternatively, to improve ventilation efficiency, a window D2 installed on a wall symmetrical to the wall where window D2 is installed may be opened. In window D1, both the first sash 31 and the second sash 51 may be opened.

[0172] Figure 18 shows a southerly wind W1 blowing. That is, the wind direction acquired in step S105 is south. Here, the acquired wind direction corresponds to the set wind direction "south to south-southeast" for the door / window identifier "D1b" among the set wind directions stored in the table in Figure 16. At this time, it is determined that there is a door / window to be opened (step S106: yes). The door / window to be opened determination unit 314 determines that the door / window to be opened is the second sash 51 of window D1. Subsequently, the opening / closing instruction unit 315 sends an opening instruction to the electric equipment that controls the opening and closing of the second sash 51 (i.e., the second electric unit 111B) in order to open the second sash 51 of window D1, causing the second sash 51 to open (step S107). The first sash 31 of window D1 and window D2 may remain closed as shown in Figure 18. If the first sash 31 and window D2 are open, control may be made to close the first sash 31 and window D2. Alternatively, to improve ventilation efficiency, window D2, which is installed on a wall symmetrical to the wall where window D1 is installed, may also be opened. In window D1, both the first sash 31 and the second sash 51 may be opened.

[0173] Figure 19 shows a westerly wind W3 blowing. That is, the wind direction acquired in step S105 is west. Here, the acquired wind direction corresponds to the set wind direction "west" for the door / window identifier "D2" among the set wind directions stored in the table in Figure 16. At this time, it is determined that there is a door / window to be opened (step S106: yes). The door / window to be opened determination unit 314 determines that the door / window to be opened is window D2. Subsequently, the opening / closing instruction unit 315 sends an opening instruction to the electric equipment that controls the opening and closing of window D2 in order to open window D2, causing window D2 to open (step S107). Window D1 (first sash 31 and second sash 51) may remain closed as shown in Figure 19. If the first sash 31 and second sash 51 are in an open state, they may be controlled to close. Alternatively, to improve ventilation efficiency, at least one of the first sash 31 and the second sash 51, which are installed on a wall symmetrical to the wall on which window D2 is installed, may be opened.

[0174] Furthermore, if the wind direction obtained in step S105 is east and does not match any of the set wind directions stored in the table, the window opening determination unit 314 determines that there is no window to be opened (step S106: No). In this case, neither window D1 nor window D2 is opened.

[0175] Furthermore, when it is determined that there is a door or window to be opened, the determination of whether to open or close other doors or windows may be made based on, for example, the magnitude of the wind force. For example, when opening one of the first sliding door 31 and the second sliding door 51, if the wind force is above a predetermined threshold, one of the first sliding door 31 and the second sliding door 51 may be opened while the other remains closed, and if the wind force is below the predetermined threshold, both the first sliding door 31 and the second sliding door 51 may be opened.

[0176] When both the first and second sliding doors 31 and 51 are open during strong winds, there is a risk that the first and second sliding doors 31 and 51 may rattle. However, this problem can be suppressed by opening only one of the first or second sliding doors 51 during strong winds. Furthermore, when there are light winds, ventilation efficiency can be further improved by opening both the first and second sliding doors 31 and 51.

[0177] (Effects and benefits according to the third embodiment) As described above, the door and window control device 310 includes a ventilation determination unit 312 that determines to perform ventilation on the building H, a wind data acquisition unit 313 that acquires wind direction data from a multi-sensor 320 associated with the building H, an open door and window determination unit 314 that determines the door and window to be opened corresponding to the wind direction data based on the door and window identifier of the door and window in the building H and the set wind direction associated with the door and window identifier, in accordance with the decision to perform ventilation, and an open / close instruction unit 315 that transmits an open operation instruction to an electric device for opening the door and window to be opened. This allows for the selection and opening of a window that is efficient in taking in outside air in the direction of the wind, and enables efficient adjustment of the indoor environment.

[0178] Window D1 is a joinery 110 according to the second embodiment. Joinery 110 can be opened in multiple directions. This allows for the selection and opening of an efficient direction for taking in outside air in the direction of the wind within a single window D1, and enables efficient adjustment of the indoor environment with a small number of joinery components. Therefore, a joinery control device 310 capable of improving ventilation efficiency can be provided.

[0179] (Computer configuration) As shown in Figure 20, each embodiment of the computer 330 in this disclosure comprises a processor 331, main memory 332, storage 333, and an interface 334.

[0180] The above-described door and window control device 310 is implemented in the computer 330. The operation of each of the above-described processing units is stored in storage 333 in the form of a program. The processor 331 reads the program from storage 333, loads it into main memory 332, and executes the above-described processing according to the program. The processor 331 also allocates memory areas in main memory 332 corresponding to each of the above-described memory units according to the program.

[0181] The program may be for the purpose of realizing some of the functions to be performed by the computer 330. For example, the program may perform functions in combination with other programs already stored in storage, or in combination with other programs implemented in other devices. In other embodiments, the computer may be equipped with a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or instead of the above configuration. Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), FPGA (Field Programmable Gate Array), etc. In this case, some or all of the functions realized by the processor may be realized by the integrated circuit.

[0182] Examples of storage 333 include HDDs, SSDs, magnetic disks, magneto-optical disks, CD-ROMs (Compact Disc Read Only Memory), DVD-ROMs (Digital Versatile Disc Read Only Memory), and semiconductor memory. Storage 333 may be an internal medium directly connected to the bus of computer 330, or an external medium connected to computer 330 via interface 334 or a communication line. Furthermore, if this program is distributed to computer 330 via a communication line, computer 330 may receive the program, expand it into main memory 332, and execute the above processing. In at least one embodiment, storage 333 is a tangible storage medium that is not temporary.

[0183] While embodiments of the building components described herein have been explained above, the invention is not limited to the embodiments described above, and any modifications, improvements, etc., within the scope that can achieve the purpose of this disclosure are included. Various modifications and changes that do not depart from the gist of this disclosure are included herein.

[0184] In the embodiments described above, the first sliding door 31 was a left-opening sliding door and the second sliding door 51 was a right-opening sliding door. However, the first sliding door 31 may be a right-opening sliding door and the second sliding door 51 may be a left-opening sliding door.

[0185] In the embodiments described above, the joinery 10 was a ventilation window, but it is not limited to this. The joinery may be for expelling air from the inside of the building to the outside (for example, a smoke vent window), or it may be for allowing air to circulate between the outside and inside of the building.

[0186] In the embodiments described above, the first and second sliding doors were both vertical sliding windows, but the invention is not limited to this. The first and second sliding doors may be, for example, horizontal sliding windows. This allows for efficient intake of wind blowing from one side in the vertical direction and wind blowing from the other side in the vertical direction into the room. It is also possible to make one of the first sash 31 and the second sash 51 a vertical sliding door and the other a horizontal sliding door. For example, the arrangement of the functional components constituting one of the first and second sliding doors may be shifted by 90 degrees relative to the arrangement of the functional components constituting the other sash. In that case, for example, the joinery may be configured to have a horizontal sliding window that opens downwards and a smoke vent window that opens upwards, and these windows can be used interchangeably depending on the purpose. This makes the joinery 10 multifunctional. The joinery may also slide outwards toward the interior. In that case, since the door 10 can be opened and closed in multiple directions, the constraints on the interior design caused by the arrangement of the door 10 can be alleviated.

[0187] In each of the embodiments described above, the joinery had two shoji screens, but the number of shoji screens provided by the joinery 10 may be three or more.

[0188] In the embodiments described above, the entire circumferential portion of the second frame 52 constituted a part of the first frame 32, but the embodiment is not limited to this. For example, the space enclosed by the first frame body 34 may be partitioned by a rail, and the second shoji screen 51 may be placed in one of the partitioned spaces, while a non-opening / closing facing material may be placed in the other space. In this case, the first shoji screen has multiple facing materials. Of the multiple facing materials that constitute the first shoji screen, only some of the facing materials belong to both the first shoji screen and the second shoji screen, while the other facing materials belong only to the first shoji screen and do not belong to the second shoji screen. However, the configuration of the embodiments described above is preferred because it allows for increased ventilation efficiency by enlarging the second shoji screen 51 and simplifies the configuration of the joinery 10.

[0189] Each device in the third embodiment may consist of multiple devices. Each device in the third embodiment may be implemented using cloud computing.

[0190] In the third embodiment described above, the number of joinery 110 of the second embodiment installed in building H was one, but there may be two or more. Furthermore, the joinery applied in the third embodiment is not limited to the joinery 110 of the second embodiment, but may be, for example, various modified or altered versions of the joinery 110 of the second embodiment.

[0191] [Aspect 1] A joinery comprising a frame, a first sliding door that rotates and slides out to open, and a second sliding door that rotates and slides out to open, wherein the second sliding door constitutes a part of the first sliding door, and the direction of rotation of the first sliding door when open and the direction of rotation of the second sliding door when open are different from each other.
