[0008] The directions in each diagram are defined below. X1 in the diagram indicates the outdoor side of the fitting 1, and X2 indicates the indoor side of the fitting 1. In the fitting 1, the surface that faces the outdoor side X1 is called the outdoor facing surface, and the surface that faces the indoor side X2 is called the indoor facing surface. In the fitting 1, the left-right direction along the outdoor facing surface and the indoor facing surface is called the facing direction. In the fitting 1, the direction that is perpendicular to the outdoor facing surface and the indoor facing surface and that runs along the straight line connecting the outdoor side X1 and the indoor side X2 is called the projection direction. In the fitting 1, the surface that is positioned along the projection direction is called the projection surface.

[0009] 3, the upper horizontal frame 21 has an indoor rail 211, an outdoor rail 212, and a screen rail 213 that extend longitudinally from the indoor side X2 toward the outdoor side X1 in that order. The lower horizontal frame 22 has an indoor rail 221, an outdoor rail 222, and a screen rail 223 that extend longitudinally from the indoor side X2 toward the outdoor side X1 in that order.

[0010] Resin cover materials 214, 215 are attached between the indoor rail 211 and the outdoor rail 212 in the upper horizontal frame 21 and on the indoor side X2 of the indoor rail 211. Resin cover materials 224, 225 are attached between the indoor rail 221 and the outdoor rail 222 in the lower horizontal frame 22 and on the indoor side X2 of the indoor rail 221.

[0011] The first shoji screen 3 and the second shoji screen 4 are attached so as to be slidable left and right along the inside rails 211, 221 of the upper horizontal frame 21 and the lower horizontal frame 22. The third shoji screen 5 and the fourth shoji screen 6 are attached so as to be slidable left and right along the outside rails 212, 222 of the upper horizontal frame 21 and the lower horizontal frame 22. The first screen door 7 and the second screen door 8 are attached so as to be slidable left and right along the screen door rails 213, 223 of the upper horizontal frame 21 and the lower horizontal frame 22. The fitting 1 of this embodiment is configured so that the inside of the frame body 2 is closed by four shoji screens, the first shoji screen 3 to the fourth shoji screen 6. The first shoji screen 3 to the fourth shoji screen 6 each have the same width. The first screen door 7 and the second screen door 8 each have the same width corresponding to one shoji screen.

[0012] As shown in Fig. 1, the first shoji screen 3 has an upper frame 31 and a lower frame 32 extending horizontally, a leading edge vertical frame 33 extending vertically on the leading edge side (right side in Fig. 1), and a trailing edge vertical frame 34 extending vertically on the trailing edge side (left side in Fig. 1), which are assembled into a rectangular frame body 30. A face material 35 is housed inside the frame body 30. As shown in Fig. 3, the face material 35 is made up of three glass sheets stacked with a spacer 351 sandwiched between them. The leading edge vertical frame 33 of the first shoji screen 3 is the first leading edge vertical frame, and the trailing edge vertical frame 34 is the first trailing edge vertical frame.

[0013] The upper frame 31 of the first shoji screen 3 has a composite structure in which a resin frame 312 is attached to the room inside X2 of a metal frame 311 made of aluminum or the like. The lower frame 32 of the first shoji screen 3 has a composite structure in which a resin frame 322 is attached to the room inside X2 of a metal frame 321 made of aluminum or the like. A crescent lock 36 for locking and unlocking the third shoji screen 5 is provided on the first vertical frame 34 on the trailing edge of the door.

[0014] As shown in FIG. 1, the second shoji screen 4 is located to the right of the first shoji screen 3 when the fitting 1 is viewed from the room inside X2 in the closed state. The second shoji screen 4 has an upper frame 41 and a lower frame 42 extending horizontally, a leading edge vertical frame 43 extending vertically on the leading edge side (left side in FIG. 1), and a trailing edge vertical frame 44 extending vertically on the trailing edge side (right side in FIG. 1), which are assembled into a rectangular frame body 40. A face material 45 is housed inside the face material 45, similar to the face material 35 of the first shoji screen 3. The leading edge vertical frame 43 of the second shoji screen 4 is the second leading edge vertical frame, and the trailing edge vertical frame 44 is the second trailing edge vertical frame.

[0015] The upper and lower frames 41 and 42 of the second shoji screen 4, like the upper and lower frames 31 and 32 of the first shoji screen 3, each have a composite structure in which a resin frame is attached to the interior side X2 of a metal frame such as aluminum. A crescent lock 46 is provided on the vertical frame 44 at the end of the door to lock and unlock the fourth shoji screen 6.

[0016] As shown in FIG. 1, the third shoji screen 5 is located to the left of the first shoji screen 3 when the fitting 1 is viewed from the room inside side X2 in the closed state. The third shoji screen 5 has an upper frame 51 and a lower frame 52 extending horizontally, a leading edge vertical frame 53 extending vertically on the leading edge side (left side in FIG. 1), and a trailing edge vertical frame 54 extending vertically on the trailing edge side (right side in FIG. 1), which are assembled into a rectangular frame body 50. A face material 55 is housed inside the frame body 50. Like the face material 35 of the first shoji screen 3, the leading edge vertical frame 53 of the third shoji screen 5 is the third leading edge vertical frame, and the trailing edge vertical frame 54 is the third trailing edge vertical frame.

[0017] The upper and lower frames 51 and 52 of the third shoji screen 5, like the upper and lower frames 31 and 32 of the first shoji screen 3, each have a composite structure in which a resin frame is attached to the indoor side X2 of a metal frame such as aluminum. The lower frame 52 of the third shoji screen 5 is provided with an auxiliary locking mechanism 56 that locks with the lower end of the vertical frame 34 on the door tail side of the first shoji screen 3.

[0018] As shown in FIG. 1, the fourth shoji screen 6 is located to the right of the second shoji screen 4 when the fitting 1 is viewed from the room inside X2 in the closed state. The fourth shoji screen 6 has an upper frame 61 and a lower frame 62 extending horizontally, a leading edge vertical frame 63 extending vertically on the leading edge side (right side in FIG. 1), and a trailing edge vertical frame 64 extending vertically on the trailing edge side (left side in FIG. 1), which are assembled into a rectangular frame body 60. A face material 65 is housed inside the frame body 60. Like the face material 35 of the first shoji screen 3, the leading edge vertical frame 63 of the fourth shoji screen 6 is the fourth leading edge vertical frame, and the trailing edge vertical frame 64 is the fourth trailing edge vertical frame.

[0019] The upper and lower frames 61 and 62 of the fourth shoji screen 6, like the upper and lower frames 31 and 32 of the first shoji screen 3, each have a composite structure in which a resin frame is attached to the interior side X2 of a metal frame such as aluminum. The lower frame 62 of the fourth shoji screen 6 is provided with an auxiliary locking mechanism 66 that locks with the lower end of the vertical frame 44 on the door tail side of the second shoji screen 4.

[0020] As shown in FIG. 1, in the closed state of the fitting 1, the leading edge stile 33 of the first shoji screen 3 and the leading edge stile 43 of the second shoji screen 4 are butted against each other at the center of the left-right direction of the frame body 2. This forms a butt joint 10 on the leading edge sides of each of the first shoji screen 3 and the second shoji screen 4. The trailing edge stile 54 of the third shoji screen 5 is positioned so as to overlap the outside side X1 of the trailing edge stile 34 of the first shoji screen 3. This forms a joint 11 on the trailing edge sides of the first shoji screen 3 and the third shoji screen 5. The trailing edge stile 64 of the fourth shoji screen 6 is positioned so as to overlap the outside side X1 of the trailing edge stile 44 of the second shoji screen 4. This forms a joint 12 on the trailing edge sides of the second shoji screen 4 and the fourth shoji screen 6.

[0021] When the fitting 1 is viewed from the inside X2, as shown in Figure 2, the width W1 of the entire butt joint 10 when the leading edge vertical stile 33 of the first shoji 3 and the leading edge vertical stile 43 of the second shoji 4 are butted together is the same as the width W2 of the joint 11 formed by the trailing edge vertical stile 34 of the first shoji 3 and the trailing edge vertical stile 54 of the third shoji 5, and the width W3 of the joint 12 formed by the trailing edge vertical stile 44 of the second shoji 4 and the trailing edge vertical stile 64 of the fourth shoji 6. Therefore, when the fitting 1 is observed as a whole, the butt joint 10 and the joints 11, 12 appear to have the same width, which provides excellent design. Being equivalent does not necessarily mean that the widths W1, W2, and W3 are perfectly identical, but rather that there may be manufacturing errors in each vertical frame 33, 34, 43, and 44 to the extent that they are perceived as being the same width when viewed from the inside X2 of the room.

[0022] Next, the configuration of the abutment portion 10 will be described with reference to Figure 4. The abutment portion 10 is formed by abutting the leading edge vertical stile 33 of the first shoji screen 3 and the leading edge vertical stile 43 of the second shoji screen 4 from the left and right when the first shoji screen 3 and the second shoji screen 4 are closed. The leading edge vertical stiles 33, 43 do not have a shape in which one stile covers and swallows the interior facing surface of the other stile.

[0023] The leading edge vertical frame 33 of the first shoji screen 3 has a metal leading edge vertical frame main body 331, an indoor side protrusion 332 provided on the indoor side X2 of the leading edge vertical frame main body 331, and an outdoor side protrusion 333 provided on the outdoor side X1 of the leading edge vertical frame main body 331.

[0024] The door-front side vertical stile body 331 is formed in the shape of a plate extending in the front and vertical directions so as to cover the front surface of the door-front side grating channel 352 in the face material 35. An exterior protruding piece 3311 extending in the front direction toward the second shoji screen 4 is integrally provided at the end of the exterior side X1 of the door-front side vertical stile body 331. An elastic exterior fin member 3312 is attached to the interior side X2 surface of the exterior protruding piece 3311.

[0025] The indoor side protrusion 332 protrudes toward the indoor side X2 beyond the face material 35. The indoor side protrusion 332 is composed of a metal protrusion main body 3321 and a resin cover 3322 that covers the outside of the protrusion main body 3321.

[0026] The protrusion body 3321 is formed integrally with the leading-edge stile body 331. The protrusion body 3321 is formed in a rectangular shape that is long in the front direction, and has a hollow portion 3321a inside. The protrusion body 3321 protrudes further toward the face material 35 than the leading-edge stile body 331, and is positioned so as to overlap the indoor side X2 of the spacer 351.

[0027] The resin cover 3322 is attached to the outer surface of the protrusion main body 3321 via multiple ribs 3322d at intervals to cover the entire surface. The resin cover 3322 has an inner recessed wall portion 3322a and an outer recessed wall portion 3322b arranged to cover the left and right recessed surfaces of the protrusion main body 3321, and an indoor-side recessed wall portion 3322c arranged to cover the indoor-side recessed surface of the protrusion main body 3321. The inner recessed wall portion 3322a and the outer recessed wall portion 3322b are arranged parallel to each other and extend in the recessed direction. The resin cover 3322 is attached to the outer surface of the protrusion main body 3321 via the multiple ribs 3322d, thereby forming multiple hollow portions 3322e separated by the ribs 3322d between the outer surface of the protrusion main body 3321 and the inner surface of the resin cover 3322.

[0028] The position in the projection direction of the end of the exterior side X1 of the exterior projection wall portion 3322b roughly coincides with the position of the interior side X2 surface of the panel 35. An interior side protruding piece 3323 extending in the front direction toward the second shoji screen 4 is integrally formed at the end of the exterior side X1 of the exterior projection wall portion 3322b. The amount of protrusion in the front direction of the interior side protruding piece 3323 is equal to the amount of protrusion in the front direction of the exterior side protruding piece 3311. An elastic interior side fin member 3324 is attached to the exterior side X1 surface of the interior side protruding piece 3323.

[0029] The indoor-side sight wall portion 3322c has a width sufficient to cover the leading-side stile main body 331 and the spacer 351 of the face material 35 from the indoor side X2. Furthermore, the multiple hollow portions 3322e provided between the protrusion main body 3321 and the resin cover 3322 are also arranged to cover the spacer 351 of the face material 35 from the indoor side X2. This makes it difficult to see the leading-side stile main body 331 and the spacer 351 from the indoor side X2, improving the design and thermal insulation of the leading-side side of the first shoji screen 3. The resin cover 3322 has multiple hollow portions 3322e separated by multiple ribs 3322d, improving the strength of the resin cover 3322 and eliminating the risk of bending when gripped.

[0030] The outdoor protrusion 333 protrudes further toward the outdoor side X1 than the outdoor rail 222. The outdoor-most position X1 of the outdoor protrusion 333 is close to the movement area of ​​the first screen door 7 and second screen door 8, which slide left and right on the screen door rail 223. The outdoor protrusion 333 is made of metal, and is formed integrally with the door-end vertical stile main body 331. The outdoor protrusion 333 is formed in a rectangular shape that is long in the front direction, and has a hollow portion 333a inside.

[0031] The exterior protruding portion 333 has an interior protruding wall portion 3331 and an exterior protruding wall portion 3332 that form the left and right protruding surfaces, and an exterior sight wall portion 3333 that faces the exterior side X1. The interior protruding wall portion 3331 and the exterior protruding wall portion 3332 are arranged parallel to each other and extend toward the exterior side X1. The width of the exterior sight wall portion 3333 of the exterior protruding portion 333 is equal to the width of the interior sight wall portion 3322c that forms the interior sight surface of the interior protruding portion 332. The interior protruding wall portion 3331 and the exterior protruding wall portion 3332 of the exterior protruding portion 333 are arranged on approximately the same plane along the protruding direction as the interior protruding wall portion 3322a and the exterior protruding wall portion 3322b of the resin cover 3322 of the interior protruding portion 332.

[0032] As shown in Figure 3, the upper end surface 333b of the outdoor protruding portion 333 is flush with the upper end surface 31a of the upper frame 31 of the first shoji screen 3 and is positioned higher than the lower end 212a of the outdoor rail 212 of the upper horizontal frame 21. An engagement groove 3334 that engages with the outdoor rail 212 is formed at the upper end of the outdoor protruding portion 333. An outdoor extension 3334a and an indoor extension 3334b that extend higher than the lower end 212a of the outdoor rail 212 are positioned on the outdoor side X1 and indoor side X2 of the engagement groove 3334 of the outdoor protruding portion 333, respectively. The upper end of the outdoor protruding portion 333 is engaged with the outdoor rail 212 from the outdoor side X1 and indoor side X2 by the engagement groove 3334, the outdoor extension 3334a, and the indoor extension 3334b.

[0033] The lower end surface 333c of the outdoor protruding portion 333 is flush with the lower end surface 32a of the bottom frame 32 of the first shoji screen 3, and is positioned higher than the upper end 222a of the outdoor rail 222 of the lower horizontal frame 22. An engagement groove 3335 that engages with the outdoor rail 222 is formed at the lower end of the outdoor protruding portion 333. An outdoor extension portion 3335a and an indoor extension portion 3335b that extend downward below the upper end 222a of the outdoor rail 222 are disposed on the outdoor side X1 and indoor side X2 of the engagement groove 3335 of the outdoor protruding portion 333, respectively. The lower end of the outdoor protruding portion 333 is engaged with the outdoor rail 222 by the outdoor extension portion 3335a and indoor extension portion 3335b so as to sandwich it from the outdoor side X1 and indoor side X2.

[0034] In this way, the outdoor protrusion 333 engages with the outdoor rails 212, 222 of the upper horizontal frame 21 and the lower horizontal frame 22, so that when the first shoji screen 3 receives wind pressure and moves in the forward direction, the outdoor protrusion 333 comes into contact with the outdoor rails 212, 222. This improves the wind pressure resistance of the first shoji screen 3.

[0035] The leading edge vertical frame 43 of the second shoji screen 4 has a metal leading edge vertical frame main body 431, an indoor side protrusion 432 provided on the indoor side X2 of the leading edge vertical frame main body 431, and an outdoor side protrusion 433 provided on the outdoor side X1 of the leading edge vertical frame main body 431.

[0036] The leading-edge vertical stile body 431 is formed in the shape of a plate extending in the front and vertical directions so as to cover the front surface of the leading-edge grating channel 452 in the face material 45. An exterior protruding piece 4311 extending in the front direction toward the first shoji screen 3 is integrally provided at the end of the exterior side X1 of the leading-edge vertical stile body 431. When the first shoji screen 3 and the second shoji screen 4 are closed, the exterior protruding piece 4311 is positioned so as to overlap the interior side X2 of the exterior protruding piece 3311 of the first shoji screen 3. As a result, the exterior protruding piece 4311 comes into contact with the exterior fin member 3312, forming an airtight section on the exterior side X1 of the leading-edge vertical stile body 431.

[0037] The indoor side protrusion 432 protrudes toward the indoor side X2 beyond the face material 45 by the same amount as the indoor side protrusion 332 of the first shoji screen 3. The indoor side protrusion 432 is composed of a metal protrusion main body 4321 and a resin cover 4322 that covers the outside of the protrusion main body 4321.

[0038] The protrusion body 4321 is formed integrally with the leading-edge stile body 431. The protrusion body 4321 is formed in a rectangular shape that is long in the front direction, and has a hollow portion 4321a inside. The protrusion body 4321 protrudes further toward the face material 45 than the leading-edge stile body 431, and is positioned so as to overlap the indoor side X2 of the spacer 451.

[0039] The resin cover 4322 is attached to the outer surface of the protrusion main body 4321 via multiple ribs 4322d at intervals to cover the entire surface. The resin cover 4322 has an inner front wall portion 4322a and an outer front wall portion 4322b arranged to cover the left and right front surfaces of the protrusion main body 4321, and an indoor front wall portion 4322c arranged to cover the indoor front surface of the protrusion main body 4321. The inner front wall portion 4322a and the outer front wall portion 4322b are arranged parallel to each other and extend in the front direction. By attaching the resin cover 4322 to the outer surface of the protrusion main body 4321 via the multiple ribs 4322d, multiple hollow portions 4322e separated by the ribs 4322d are formed between the outer surface of the protrusion main body 4321 and the inner surface of the resin cover 4322.

[0040] The position in the projection direction of the end of the exterior side X1 of the exterior projection wall portion 4322b roughly coincides with the position of the surface of the interior side X2 of the face material 45. An interior side protruding piece 4323 extending in the projection direction toward the first shoji screen 3 is integrally formed at the end of the exterior side X1 of the exterior projection wall portion 4322b. The amount of protrusion in the projection direction of the interior side protruding piece 4323 is equal to the amount of protrusion in the projection direction of the exterior side protruding piece 4311. When the first shoji screen 3 and the second shoji screen 4 are closed, the interior side protruding piece 4323 is positioned so as to overlap the exterior side X1 of the interior side protruding piece 3323 of the first shoji screen 3. As a result, the interior side protruding piece 4323 comes into contact with the exterior fin member 3324, forming an airtight portion on the interior side X2 of the door-end side stile main body 431.

[0041] The indoor-side visible wall portion 4322c has a width sufficient to cover the leading-side stile main body 431 and the spacer 451 of the face material 45 from the indoor side X2. Furthermore, the multiple hollow portions 4322e provided between the protrusion main body 4321 and the resin cover 4322 are also arranged to cover the spacer 451 of the face material 45 from the indoor side X2. This makes it difficult to see the leading-side stile main body 431 and the spacer 451 from the indoor side X2, improving the design and thermal insulation of the leading-side side of the second shoji screen 4. The resin cover 4322 has multiple hollow portions 4322e separated by multiple ribs 4322d, improving the strength of the resin cover 4322 and eliminating the risk of bending when gripped.

[0042] The outdoor protrusion 433 protrudes further toward the outdoor side X1 than the outdoor rail 222 by the same amount as the outdoor protrusion 433 of the first shoji screen 3. The outdoor protrusion 433 is made of metal and is formed integrally with the door-end vertical frame body 431. The outdoor protrusion 433 is formed in a rectangular shape that is long in the projection direction, and has a hollow portion 433a inside.

[0043] The exterior protruding portion 433 has an interior prospective wall portion 4331 and an exterior prospective wall portion 4332 that form the left and right prospective surfaces, and an exterior sight wall portion 4333 that faces the exterior side X1. The interior prospective wall portion 4331 and the exterior prospective wall portion 4332 are arranged parallel to each other and extend toward the exterior side X1. The width of the exterior sight wall portion 4333 of the exterior protruding portion 433 is equal to the width of the interior sight wall portion 4322c that forms the interior sight surface of the interior protruding portion 432. The interior prospective wall portion 4331 and the exterior prospective wall portion 4332 of the exterior protruding portion 433 are arranged on approximately the same plane along the prospective direction as the interior prospective wall portion 4322a and the exterior prospective wall portion 4322b of the resin cover 4322 of the interior protruding portion 433.

[0044] Although not shown, the upper and lower ends of the outdoor protrusion 433 of the second shoji screen 4 are also provided with engagement grooves that engage with the outdoor rails 212, 222 of the upper horizontal frame 21 and the lower horizontal frame 22, and outdoor extensions and indoor extensions that are located on the outdoor side X1 and indoor side X2 of the engagement grooves, similar to the outdoor protrusion 333 of the first shoji screen 3 shown in Fig. 3, and the outdoor protrusion 433 engages with the outdoor rails 212, 222 of the upper horizontal frame 21 and the lower horizontal frame 22. Therefore, when the second shoji screen 4 is affected by wind pressure and moves in the forward direction, the outdoor protrusion 433 comes into contact with the outdoor rails 212, 222, improving wind pressure resistance.

[0045] The width W1 of the butt joint 10 is the overall width of the two indoor protrusions 332, 432 and the overall width of the two outdoor protrusions 333, 433, and is the same on the outdoor side X1 and the indoor side X2. The width W1 of the butt joint 10 is the distance between the inner protrusion wall 3322a of the indoor protrusion 332 of the first shoji screen 3 and the inner protrusion wall 4322a of the indoor protrusion 432 of the second shoji screen 4, and is the distance between the inner protrusion wall 3331 of the outdoor protrusion 333 of the first shoji screen 3 and the inner protrusion wall 4331 of the outdoor protrusion 433 of the second shoji screen 4.

[0046] The width W1a of the leading edge vertical stile 33 of the first shoji 3 and the width W1b of the leading edge vertical stile 43 of the second shoji 4 at the butt joint 10 are set to be less than half the width W2 of the trailing edge vertical stile 34 of the first shoji 3 constituting the joint 11 shown in Figure 2 and the width W3 of the trailing edge vertical stile 44 of the second shoji 4 constituting the joint 12. The leading edge vertical stiles 33, 43 do not need to be configured so that one stile covers and swallows the interior facing surface of the other stile, and the overall width W1 of the butt joint 10 can easily be unified with the widths W2, W3 of the joints 11, 12. In this embodiment, the widths W1a, W1b are formed to be the same, but they do not necessarily have to be the same.

[0047] In this embodiment, the widths W1a, W1b of the leading edge stiles 33, 43 are smaller than half the widths W2, W3 of the joints 11, 12. Therefore, when the first shoji screen 3 and the second shoji screen 4 are closed, a gap S is formed between the leading edge stile 33 of the first shoji screen 3 and the leading edge stile 43 of the second shoji screen 4 on the exterior side X1 and the interior side X2, respectively. This gap S can be used as a handle space for inserting fingers when opening or closing the first shoji screen 3 and the second shoji screen 4, improving the operability of the first shoji screen 3 and the second shoji screen 4. By forming the gap S between the leading edge stiles 33, 43, there is no risk of fingers getting caught between the leading edge stiles 33, 43 when closing the first shoji screen 3 and the second shoji screen 4.

[0048] Next, the configuration of the joint 11 will be explained with reference to Figure 5. The joint 11 is formed by overlapping the trailing edge vertical frame 34 of the first shoji screen 3 and the trailing edge vertical frame 54 of the third shoji screen 5 in the front direction when the first shoji screen 3 and the third shoji screen 5 are closed.

[0049] The trailing edge side vertical frame 34 of the first shoji screen 3 is composed of a metal trailing edge side vertical frame main body 341 and a resin cover 342 provided to cover the outer surface of the trailing edge side vertical frame main body 341.

[0050] The trailing edge side stile body 341 covers the visible surface of the grating channel 352 on the trailing edge side of the face material 35 and is arranged to protrude further toward the room interior X2 than the face material 35. A rectangular first hollow portion 341a and a second hollow portion 341b are provided inside the trailing edge side stile body 341. The first hollow portion 341a is arranged to cover the visible surface of the grating channel 352. The second hollow portion 341b is arranged on the room interior X2 of the first hollow portion 341a and protrudes further toward the room interior X2 than the face material 35 of the first shoji screen 3. A partition wall 341c extending in the visible direction is formed between the first hollow portion 341a and the second hollow portion 341b.

[0051] In the vertical stile main body 341 on the door end side, the outdoor sight wall portion 341d located on the outdoor side X1 of the first hollow portion 341a and the indoor sight wall portion 341e located on the indoor side X2 of the second hollow portion 341b are each formed to be thicker in the forward direction than the other wall portions extending in the forward direction.

[0052] The end of the trailing edge side stile body 341 on the outside side X1 protrudes further toward the outside side X1 than the face material 35. At the end of the trailing edge side stile body 341 on the outside side X1, a support piece 3411 protrudes further in the finder direction toward the door tip (right side in FIG. 5) than the first hollow portion 341a. The support piece 3411 abuts against the trailing edge side grating channel 352 from the outside side X1.

[0053] A groove 3412 is formed on the outdoor side X1 of the support piece 3411 of the trailing edge side stile main body 341. The groove 3412 is formed so as to be recessed from the door tip side (right side in FIG. 5) toward the door tip side (left side in FIG. 5) along the support piece 3411. The groove 3412 has a shape that opens toward the door tip side.

[0054] The resin cover 342 is attached so as to cover the recessed surface and the interior facing surface of the trailing edge side stile main body 341. The resin cover 342 has an inner recessed wall portion 342a and an outer recessed wall portion 342b arranged so as to cover the left and right recessed surfaces of the trailing edge side stile main body 341, and an interior facing wall portion 342c arranged so as to cover the interior facing surface of the trailing edge side stile main body 341. The inner recessed wall portion 342a and the outer recessed wall portion 342b are arranged parallel to each other and extend in the recessed direction.

[0055] The outside X1 end of the inner projection wall 342a abuts against the trailing edge grating channel 352 from the inside X2, and supports the surface material 35 by sandwiching it between the support piece 3411. The outer projection wall 342b extends in the projection direction so as to cover the entire outer projection surface of the trailing edge stile main body 341. The inside projection wall 342c has a width sufficient to cover the trailing edge stile main body 341 and the spacer 351 of the surface material 35 from the inside X2. Because the trailing edge stile main body 341 and the spacer 351 are difficult to see from the inside X2, the design and insulation of the trailing edge side of the first shoji screen 3 are improved.

[0056] The trailing edge side vertical frame 54 of the third shoji screen 5 is composed of a trailing edge side vertical frame main body 541 made of metal and a resin cover 542.

[0057] The trailing edge side stile body 541 is provided so as to cover the visible surface of the trailing edge side grating channel 552 in the face material 55. Inside the trailing edge side stile body 541, a hollow portion 541a is provided.

[0058] A support piece 5411 protrudes in the viewing direction from the end of the trailing edge side vertical stile body 541 on the outdoor side X1 beyond the hollow portion 541a toward the door tip side (left side in FIG. 5). The support piece 5411 abuts against the trailing edge side grating channel 552 from the outdoor side X1.

[0059] A protruding piece 5412 that protrudes toward the door tip (left side in Fig. 5) is formed at the end of the room inside X2 of the trailing edge side vertical stile body 541. When the first shoji screen 3 and the third shoji screen 5 are in a closed state, the protruding piece 5412 is inserted into a recessed groove 3412 provided on the room outside X1 of the trailing edge side vertical stile 34 of the first shoji screen 3, thereby forming a labyrinth structure.

[0060] An elastic fin member 5413 that protrudes toward the inside X2 is attached to the end of the trailing edge side stile body 541 of the trailing edge side stile body 541, outside the viewing direction (to the right in Figure 5) from the protruding piece 5412. When the first shoji screen 3 and the third shoji screen 5 are closed, the fin member 5413 comes into contact with the support piece 3411 of the trailing edge side stile 34 of the first shoji screen 3 from the outside X1, forming an airtight section between the trailing edge side stiles 34, 54.

[0061] The resin cover 542 is attached so as to protrude inward in the projection direction (left side in Fig. 5) from the end of the trailing edge side vertical stile main body 541 on the indoor side X2. The resin cover 542 abuts against the grating channel 552 on the trailing edge side of the third shoji screen 5 from the indoor side X2, and supports the face material 55 by sandwiching it between the resin cover 542 and the support piece 5411. The resin cover 542 covers the spacer 551 of the face material 55 from the indoor side X2. Because the spacer 551 is difficult to see from the indoor side X2, the design and thermal insulation of the trailing edge side of the third shoji screen 5 are improved.

[0062] The width W2 of the joint 11 when the fitting 1 is viewed from the inside X2 of the room is the width of the interior facing wall portion 342c of the resin cover 342 of the trailing edge vertical frame 34 of the first shoji screen 3. The width of the trailing edge vertical frame 54 of the third shoji screen 5 is equal to the width of the interior facing wall portion 342c of this resin cover 342. Therefore, when the fitting 1 is viewed from the inside X2 with the first shoji screen 3 and the third shoji screen 5 closed, the trailing edge vertical frame 54 of the third shoji screen 5 is positioned so as to be completely hidden by the exterior side X1 of the trailing edge vertical frame 34 of the first shoji screen 3.

[0063] Next, the structure of the joint 12 will be explained with reference to Figure 6. The joint 12 is formed by overlapping the trailing edge vertical frame 44 of the second shoji screen 4 and the trailing edge vertical frame 64 of the fourth shoji screen 6 in the front direction when the second shoji screen 4 and the fourth shoji screen 6 are closed. The joint 12 has a bilaterally symmetrical structure to the joint 11.

[0064] The trailing edge side vertical frame 44 of the second shoji screen 4 is composed of a metal trailing edge side vertical frame main body 441 and a resin cover 442 provided to cover the outer surface of the trailing edge side vertical frame main body 441.

[0065] The trailing edge side stile body 441 covers the visible surface of the grating channel 452 on the trailing edge side of the face material 45 and is arranged to protrude further toward the room interior X2 than the face material 45. A rectangular first hollow portion 441a and a second hollow portion 441b are provided inside the trailing edge side stile body 441. The first hollow portion 441a is arranged to cover the visible surface of the grating channel 452. The second hollow portion 441b is arranged on the room interior X2 of the first hollow portion 441a and protrudes further toward the room interior X2 than the face material 45 of the second shoji screen 4. A partition wall 441c extending in the visible direction is formed between the first hollow portion 441a and the second hollow portion 441b.

[0066] In the door end side vertical frame main body 441, the outdoor sight wall portion 441d located on the outdoor side X1 of the first hollow portion 441a and the indoor sight wall portion 441e located on the indoor side X2 of the second hollow portion 441b are each formed to be thicker in the forward direction than the other wall portions extending in the forward direction.

[0067] The end of the trailing edge side stile body 441 on the outside side X1 protrudes further toward the outside side X1 than the face material 45. At the end of the trailing edge side stile body 441 on the outside side X1, a support piece 4411 protrudes further in the finder direction than the first hollow portion 441a toward the door tip (left side in FIG. 6). The support piece 4411 abuts against the trailing edge side grating channel 452 from the outside side X1.

[0068] A groove 4412 is formed on the outdoor side X1 of the support piece 4411 of the trailing edge side stile body 441. The groove 4412 is formed so as to be recessed from the door tip side (left side in FIG. 6) toward the door trailing edge side (right side in FIG. 6) along the support piece 4411. The groove 4412 has a shape that opens toward the door tip side.

[0069] The resin cover 442 is attached so as to cover the recessed surface and the interior facing surface of the trailing edge side stile main body 441. The resin cover 442 has an inner recessed wall portion 442a and an outer recessed wall portion 442b arranged so as to cover the left and right recessed surfaces of the trailing edge side stile main body 441, and an interior facing wall portion 442c arranged so as to cover the interior facing surface of the trailing edge side stile main body 441. The inner recessed wall portion 442a and the outer recessed wall portion 442b are arranged parallel to each other and extend in the recessed direction.

[0070] The outside X1 end of the inner projection wall 442a abuts against the trailing edge side grating channel 452 from the indoor side X2, and supports the surface material 45 by sandwiching it between the support piece 4411. The outer projection wall 442b extends in the projection direction so as to cover the entire outer projection surface of the trailing edge side stile main body 441. The indoor projection wall 442c has a width sufficient to cover the trailing edge side stile main body 441 and the spacer 451 of the surface material 45 from the indoor side X2. Because the trailing edge side stile main body 441 and the spacer 451 are difficult to see from the indoor side X2, the design and insulation of the trailing edge side of the second shoji screen 4 are improved.

[0071] The trailing edge side vertical frame 64 of the fourth shoji screen 6 is composed of a trailing edge side vertical frame main body 641 made of metal and a resin cover 642.

[0072] The trailing edge side stile body 641 is provided so as to cover the visible surface of the trailing edge side grating channel 652 in the face material 65. Inside the trailing edge side stile body 641, a hollow portion 641a is provided.

[0073] A support piece 6411 protrudes in the viewing direction from the end of the trailing edge side vertical stile body 641 on the outdoor side X1 beyond the hollow portion 641a toward the door tip side (the right side in FIG. 6). The support piece 6411 abuts against the trailing edge side grating channel 652 from the outdoor side X1.

[0074] A protruding piece 6412 that protrudes toward the door tip (the right side in Fig. 6) is formed at the end of the room inside X2 of the trailing edge side vertical stile body 641. When the second shoji screen 4 and the fourth shoji screen 6 are closed, the protruding piece 6412 is inserted into a recessed groove 4412 provided on the room outside X1 of the trailing edge side vertical stile 44 of the second shoji screen 4, thereby forming a labyrinth structure.

[0075] An elastic fin member 6413 that protrudes toward the inside X2 is attached to the end of the trailing edge side stile body 641 on the inside X2 side, outside the viewing direction (left side in Figure 6) of the protruding piece 6412. When the second shoji screen 4 and the fourth shoji screen 6 are closed, the fin member 6413 comes into contact with the support piece 4411 of the trailing edge side stile 44 of the second shoji screen 4 from the outside X1, forming an airtight section between the trailing edge side stiles 44, 64.

[0076] The resin cover 642 is attached so as to protrude inward in the projection direction (to the right in Figure 6) from the end of the trailing edge side vertical stile main body 641 on the indoor side X2. The resin cover 642 abuts against the trailing edge side grating channel 652 of the fourth shoji screen 6 from the indoor side X2, and supports the face material 65 by sandwiching it between the resin cover 642 and the support piece 6411. The resin cover 642 covers the spacer 651 of the face material 65 from the indoor side X2. Because the spacer 651 is difficult to see from the indoor side X2, the design and thermal insulation of the trailing edge side of the fourth shoji screen 6 are improved.

[0077] The width W3 of the joint 12 when the fitting 1 is viewed from the inside X2 of the room is the width of the interior facing wall portion 442c of the resin cover 442 of the trailing edge vertical frame 44 of the second shoji screen 4. The width of the trailing edge vertical frame 64 of the fourth shoji screen 6 is equal to the width of the interior facing wall portion 442c of this resin cover 442. Therefore, when the fitting 1 is viewed from the inside X2 of the room with the second shoji screen 4 and the fourth shoji screen 6 closed, the trailing edge vertical frame 64 of the fourth shoji screen 6 is positioned so as to be completely hidden by the exterior side X1 of the trailing edge vertical frame 44 of the second shoji screen 4.

[0078] As shown in Figures 2 and 4 to 6, the exterior sight walls 3333, 4333, 5414, and 6414 that constitute the exterior sight surfaces of the leading edge vertical frame 33 of the first shoji screen 3, the leading edge vertical frame 43 of the second shoji screen 4, the trailing edge vertical frame 54 of the third shoji screen 5, and the trailing edge vertical frame 64 of the fourth shoji screen 6 are arranged in the same position in the projection direction of the fitting 1. In other words, the exterior sight walls 3333, 4333, 5414, and 6414 are arranged on the same plane along the projection direction.

[0079] Next, we will explain the first screen door 7 and the second screen door 8. The first screen door 7 and the second screen door 8 slide left and right along the same screen door rails 213, 223. When viewing the fitting 1 from the inside X2, the first screen door 7 is located on the left side, and the second screen door 8 is located on the right side.

[0080] As shown in Figures 2 and 3, the first screen door 7 has a mesh body 75 stretched inside a rectangular frame body 70 made up of an upper frame 71 and a lower frame 72 that extend horizontally, a front-end vertical frame 73 that extends vertically on the front end side (right side in Figure 2), and a rear-end vertical frame 74 that extends vertically on the rear end side (left side in Figure 2). The front-end vertical frame 73 of the first screen door 7 is the front-end vertical frame for the first screen door, and the rear-end vertical frame 74 is the rear-end vertical frame for the first screen door.

[0081] As shown in Figures 2 and 4, when the first shoji screen 3 to the fourth shoji screen 6 are in a closed state and the first screen door 7 and the second screen door 8 are butted against each other in the left-right center of the frame body 2, the leading edge vertical frame 73 of the first screen door 7 is positioned on the outside side X1 of the leading edge vertical frame 33 of the first shoji screen 3, and the trailing edge vertical frame 74 is positioned on the outside side X1 of the trailing edge vertical frame 54 of the third shoji screen 5.

[0082] As shown in Figure 4, the leading edge vertical frame 73 of the first screen door 7 is provided with a shock absorber 731 that protrudes toward the interior side X2. The shock absorber 731 is made of, for example, mohair or packing. The shock absorber 731 is located at the end of the leading edge vertical frame 73 on the outside in the facing direction (the right side in Figure 4). The shock absorber 731 abuts against the exterior facing wall portion 3333 that forms the exterior facing surface of the leading edge vertical frame 33 of the first shoji screen 3 from the exterior side X1.

[0083] As shown in Fig. 5, the trailing edge stile 74 of the first screen door 7 is provided with a shock absorber 741 that protrudes toward the interior side X2. The shock absorber 741 is made of mohair or packing, for example. The shock absorber 741 is located at the end of the trailing edge stile 74 on the outside in the front view direction (on the left side in Fig. 5). The shock absorber 741 abuts against the trailing edge stile 54 of the third shoji screen 5 from the exterior side X1. More specifically, the shock absorber 741 abuts against the exterior sight wall 5414 of the trailing edge stile main body 541 that forms the exterior sight surface of the trailing edge stile 54, or against a support piece 5411 that is continuous with the exterior sight wall 5414 in the front view direction, from the exterior side X1.

[0084] Similar to the first screen door 7, the second screen door 8 has a mesh body 85 stretched inside a rectangular frame body 80 made up of upper and lower frames (not shown) that extend horizontally, a front-end vertical frame 83 that extends vertically on the front end side (left side in Figure 2), and a trailing-end vertical frame 84 that extends vertically on the trailing-end side (right side in Figure 2). The front-end vertical frame 83 of the second screen door 8 is the front-end vertical frame for the second screen door, and the trailing-end vertical frame 84 is the trailing-end vertical frame for the second screen door.

[0085] As shown in Figures 2 and 4, when the first shoji screen 3 to the fourth shoji screen 6 are in the closed state and the first screen door 7 and the second screen door 8 are butted against each other in the left-right center of the frame body 2, the leading edge vertical frame 83 of the second screen door 8 is positioned on the outside side X1 of the leading edge vertical frame 43 of the second shoji screen 4, and the trailing edge vertical frame 84 is positioned on the outside side X1 of the trailing edge vertical frame 64 of the fourth shoji screen 6.

[0086] As shown in Fig. 4, the leading edge vertical frame 83 of the second screen door 8 is provided with a shock absorber 831 that protrudes toward the indoor side X2. The shock absorber 831 is made of, for example, mohair or packing. The shock absorber 831 is disposed at the end of the leading edge vertical frame 83 on the outside in the viewing direction (the left side in Fig. 4). The shock absorber 831 abuts against the outdoor side sight wall portion 4333 that forms the outdoor side sight surface of the leading edge vertical frame 43 of the second shoji screen 4 from the outdoor side X1.

[0087] As shown in Fig. 6, the trailing edge stile 84 of the second screen door 8 is provided with a shock absorber 841 that protrudes toward the interior side X2. The shock absorber 841 is made of mohair or packing, for example. The shock absorber 841 is located at the end of the trailing edge stile 84 on the outside in the front view direction (the right side in Fig. 6). The shock absorber 841 abuts against the trailing edge stile 64 of the fourth shoji screen 6 from the exterior side X1. More specifically, the shock absorber 841 abuts against the exterior sight wall 6414 of the trailing edge stile main body 641 that forms the exterior sight surface of the trailing edge stile 64, or against a support piece 6411 that is continuous with the exterior sight wall 6414 in the front view direction, from the exterior side X1.

[0088] Here, the "contact" of the buffer members 731, 741, 831, 841 does not necessarily mean that they are in completely intimate contact with the mating member, but also includes the case where there is a small gap between them and the mating member.

[0089] FIG. 7 shows the state in which only the second shoji screen 4 has been moved in the opening direction in the fitting 1. This opens up the gap between the first shoji screen 3 and the second shoji screen 4. At this time, the second screen door 8 is moved slightly leftward from the state shown in FIG. 2, so that the buffer member 831 of the leading edge vertical stile 83 of the second screen door 8 abuts against the exterior projection 333 of the leading edge vertical stile 33 of the first shoji screen 3 from the outside X1, and the buffer member 841 of the trailing edge vertical stile 84 abuts against the trailing edge vertical stile 64 of the fourth shoji screen 6 from the outside X1. This allows the gap between the first shoji screen 3 and the second shoji screen 4 to be shielded by only the second screen door 8. In this case, it is not necessary to maintain the first screen door 7 and the second screen door 8 in a butted state. Therefore, as shown in FIG. 7, it is possible to place the first screen door 7 away from the second screen door 8.

[0090] Figures 8 to 12 show butt joints 10A to 10E according to other embodiments. Since parts with the same reference numerals as those in the butt joint 10 above have the same configuration, their explanation will be omitted below and the explanation for the butt joint 10 will be cited. The first screen door 7 and second screen door 8 are not shown in Figures 8 to 12.

[0091] The butt joint 10A shown in Figure 8 has handles 3336, 4336 on the exterior protruding portions 333, 433 of the door-end vertical stiles 33, 43 of the first shoji screen 3 and the second shoji screen 4, respectively. The handles 3336, 4336 are formed over the entire length of the exterior protruding portions 333, 433. The handles 3336, 4336 are formed by recessing the exterior protruding portions 333, 433 in a stepped manner from the exterior visible wall portions 3333, 4333 of the exterior protruding portions 333, 433 to the exterior visible wall portions 3332, 4332. This widens the gap S of the butt joint 10A toward the exterior side X1, thereby creating a larger space for handles on the exterior side X1 without changing the overall width of the butt joint 10A.

[0092] The butt joint 10B shown in Figure 9 has handles 3337, 4337 on the exterior protruding portions 333, 433 of the door-end vertical frames 33, 43 of the first shoji screen 3 and the second shoji screen 4. The handles 3337, 4337 are formed over the entire length of the exterior protruding portions 333, 433. The handles 3337, 4337 are formed by recessing the exterior X1 end of the inner prospective wall portion 3331, 4331 of the exterior protruding portion 333, 433 toward the outer prospective wall portion 3332, 4332. The width of the exterior prospective wall portion 3333, 433 of the exterior protruding portion 333, 433 is maintained. This allows the handle portions 3337, 4337 to be formed on the outside surface X1 without changing the external shape of the butt joint portion 10B when viewed from the outside surface X1 from the butt joint portion 10.

[0093] At the butt joint 10B, no gap is formed between the indoor-side protruding portions 332, 432 of the door-end vertical stiles 33, 43. The ends of the indoor-side protruding portions 332, 432 on the indoor-side X2 are formed to abut each other. More specifically, the ends of the protruding portion bodies 3321, 4321 of the indoor-side protruding portions 332, 432 and the indoor-side X2 of the resin covers 3322, 4322 protrude in a rectangular shape in the forward direction so as to abut each other and abut each other. As a result, no gap is visible from the indoor-side X2 of the butt joint 10B, further improving the design of the indoor-side X2 of the fitting 1.

[0094] The butt joint 10C shown in Figure 10 has handles 3338, 4338 on the outdoor protruding portions 333, 433 of the door-end vertical stiles 33, 43. The handles 3338, 4338 are formed over the entire length of the outdoor protruding portions 333, 433. The handles 3338, 4338 are formed by recessing the outdoor visible wall portions 3333, 4333 of the outdoor protruding portions 333, 433 toward the indoor side X2.

[0095] Hollow outdoor elastic members 3339, 4339 are attached to the ends of the outdoor-side X1 of the outer projection walls 3332, 4332 of the outdoor-side protruding portions 333, 433, respectively, on the outdoor side X1 to close the gap S on the outdoor side X1. The outdoor elastic members 3339, 4339 are formed symmetrically from an elastic material such as rubber. The outdoor elastic members 3339, 4339 are formed over the entire length of the outdoor protruding portions 333, 433, protrude in the front direction, and contact each other. This further improves the airtightness of the outdoor side X1 of the butt joint 10C.
