Door fitting

Abstract

The present invention provides a door fitting improved in aesthetic appearance by unifying lateral widths of leading-edge and trailing-edge vertical stiles of two paper sliding-doors without requiring a structure where when the leading-edge vertical stiles of two paper sliding-doors sliding on the same rail are brought into contact with each other, the leading-edge vertical stile of one paper sliding-door overlaps and covers the indoor-facing surface of the leading-edge vertical stile of the other paper sliding-door. The door fitting comprises a first paper sliding-door and a second paper sliding-door sliding on an indoor-side rail extending in the longitudinal direction of a horizontal frame. The first paper sliding-door has a first leading-edge vertical stile and a first trailing-edge vertical stile, and the second paper sliding-door has a second leading-edge vertical stile and a second trailing-edge vertical stile. In closed states of the first paper sliding-door and the second paper sliding-door, the total lateral width of the first leading-edge vertical stile and the second leading-edge vertical stile, which are brought into contact with each other, is equal to the lateral width of each of the first trailing-edge vertical stile and the second trailing-edge vertical stile.

[0007] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. As shown in Figures 1 and 2, a fitting 1 has a frame body 2 attached to an opening in a building skeleton 100. The frame body 2 is formed by framing an upper horizontal frame 21, a lower horizontal frame 22, and a pair of left and right vertical frames 23, 24, each of which is extruded from a metal material such as aluminum, into a rectangular shape. Inside the frame body 2, four shoji screens, namely a first shoji screen 3, a second shoji screen 4, a third shoji screen 5, and a fourth shoji screen 6, and two screen doors, namely a first screen door 7 and a second screen door 8, are housed.

[0008] The directions in each diagram are defined below. X1 in the diagram indicates the exterior side of the fixture, and X2 indicates the interior side of the fixture. In a fixture, the surfaces that are arranged to face the exterior side X1 and the interior side X2 are called the front surface. In a fixture, the left-right or up-down direction along the front surface is called the front direction. In a fixture, the direction along the straight line connecting the exterior side X1 and the interior side X2 is called the front direction, and the surface that is arranged along the front direction is called the front surface.

[0009] As shown in Figure 3, the upper horizontal frame 21 has an indoor rail 211, an outdoor rail 212, and a screen rail 213 that extend along the length from the indoor side X2 to 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 along the length from the indoor side X2 to 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 and lower horizontal frames 21, 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 and lower horizontal frames 21, 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 and lower horizontal frames 21, 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 widths of the first shoji screen 3 to the fourth shoji screen 6 are all the same. The first screen door 7 and the second screen door 8 each have the same width as the width of a single shoji screen.

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

[0013] As shown in Figure 3, 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 side 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 side X2 of a metal frame 321 made of aluminum or the like. As shown in Figure 1, the first trailing edge vertical frame 34 is provided with a crescent lock 36 for locking and unlocking the third shoji screen 5.

[0014] As shown in FIG. 1 , the second shoji screen 4 is located to the right of the first shoji screen 3 when viewing the closed fitting 1 from the room side X2. The second shoji screen 4 is comprised of a rectangular frame 40 consisting of an upper frame 41 and a lower frame 42 extending horizontally, a leading edge frame 43 extending vertically on the leading edge side (left side in FIG. 1 ), and a trailing edge frame 44 extending vertically on the trailing edge side (right side in FIG. 1 ). A face plate 45 is housed inside the frame 40. Like the face plate 35 of the first shoji screen 3, the leading edge frame 43 of the second shoji screen 4 is the second leading edge frame, and the trailing edge frame 44 is the second trailing edge 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. As shown in Figure 1, the end-of-door vertical frame 44 is provided with a crescent lock 46 for locking and unlocking the fourth shoji screen 6.

[0016] As shown in Figure 1, the third shoji screen 5 is located to the left of the first shoji screen 3 when viewing the closed fitting 1 from the room side X2. The third shoji screen 5 comprises a rectangular frame 50 consisting of an upper frame 51 and a lower frame 52 extending horizontally, a leading edge frame 53 extending vertically on the leading edge side (left side in Figure 1), and a trailing edge frame 54 extending vertically on the trailing edge side (right side in Figure 1). A face plate 55 is housed inside the frame 50. Similar to the face plate 35 of the first shoji screen 3, the leading edge frame 53 of the third shoji screen 5 is the third leading edge frame, and the trailing edge frame 54 is the third trailing edge frame.

[0017] The upper and lower frames 51 and 52 of the third shoji screen 5 have a composite structure in which a resin frame is attached to the interior side X2 of a metal frame such as aluminum, similar to the upper and lower frames 31 and 32 of the first shoji screen 3. 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 trailing edge vertical frame 34 of the first shoji screen 3, as shown in FIG.

[0018] As shown in Figure 1, the fourth shoji screen 6 is located to the right of the second shoji screen 4 when viewing the closed fitting 1 from the room side X2. The fourth shoji screen 6 is comprised of a rectangular frame 60 consisting of an upper frame 61 and a lower frame 62 extending horizontally, a leading edge frame 63 extending vertically on the leading edge side (right side in Figure 1), and a trailing edge frame 64 extending vertically on the trailing edge side (left side in Figure 1). A face plate 65 is housed inside the frame 60. Similar to the face plate 35 of the first shoji screen 3, the leading edge frame 63 of the fourth shoji screen 6 is the fourth leading edge frame, and the trailing edge frame 64 is the fourth trailing edge frame.

[0019] The upper and lower frames 61 and 62 of the fourth shoji screen 6 have a composite structure in which a resin frame is attached to the interior side X2 of a metal frame such as aluminum, similar to the upper and lower frames 31 and 32 of the first shoji screen 3. 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 trailing edge vertical frame 44 of the second shoji screen 4, as shown in Figure 1.

[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 in 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 interior side 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 screen 3 and the leading edge vertical stile 43 of the second shoji screen 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 screen 3 and the trailing edge vertical stile 54 of the third shoji screen 5, and the width W3 of the joint 12 formed by the trailing edge vertical stile 44 of the second shoji screen 4 and the trailing edge vertical stile 64 of the fourth shoji screen 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, resulting in excellent design. Being equivalent does not necessarily mean that the widths W1, W2, and W3 are completely the same, 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 the building fixture 1 is viewed from the inside X2.

[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 stile 33 of the first shoji screen 3 and the leading edge 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 stiles 33, 43 do not have a shape in which one stile covers and swallows the visible surface of the other stile on the interior side.

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

[0024] The 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 grating channel 352 on the door tip side of 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 stile body 331. An elastic exterior fin member 3312 is attached to the surface of the exterior side X2 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 frame body 331. The protrusion body 3321 is formed in a rectangular shape that is long in the projection direction and has a hollow portion 3321a inside. The protrusion body 3321 protrudes further toward the panel 35 than the frame 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 a plurality of ribs 3322d provided on the resin cover 3322 at intervals to completely 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 interior recessed wall portion 3322c arranged to cover the interior 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 plurality of ribs 3322d. This forms a plurality of 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 outer exterior side X1 of the outer projection wall portion 3322b roughly coincides with the position of the indoor side X2 surface of the panel 35. An indoor side protruding piece 3323 extending in the projection direction toward the second shoji screen 4 is integrally formed at the end of the outer exterior side X1 of the outer projection wall portion 3322b. The amount of protrusion in the projection direction of the indoor side protruding piece 3323 is equal to the amount of protrusion in the projection direction of the outdoor side protruding piece 3311. An elastic indoor side fin member 3324 is attached to the outdoor side X1 surface of the indoor side protruding piece 3323.

[0029] The indoor-side visible wall portion 3322c has a width sufficient to cover the stile main body portion 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 stile main body portion 331 and the spacer 351 from the indoor side X2, improving the design and insulation of the door edge 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 position of the end of the outdoor protrusion 333 on the outdoor side X1 is close to the movement area of ​​the first screen door 7 and the 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 frame main body 331. The outdoor protrusion 333 is formed in a rectangular shape that is long in the forward direction, and has a hollow portion 333a inside.

[0031] The exterior protruding portion 333 has an inner protruding wall portion 3331 and an outer 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 inner protruding wall portion 3331 and the outer 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 side sight surface of the interior protruding portion 332. The inner protruding wall portion 3331 and the outer protruding wall portion 3332 of the exterior protruding portion 333 are arranged on approximately the same plane along the protruding direction as the inner protruding wall portion 3322a and the outer 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 protrusion 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 protrusion 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 protrusion 333, respectively. The upper end of the outdoor protrusion 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 so as to sandwich it against the outdoor rail 212 from the outdoor side X1 and the indoor side X2.

[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 3335a and an indoor extension 3335b that extend downward below the upper end 222a of the outdoor rail 222 are positioned 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 3335a and indoor extension 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 vertical frame 43 on the door end side of the second shoji screen 4 has a metal frame main body 431, an indoor protrusion 432 provided on the indoor side X2 of the frame main body 431, and an outdoor protrusion 433 provided on the outdoor side X1 of the frame main body 431.

[0036] The 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 grating channel 452 on the door tip side of 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 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 portion of the exterior side X1 of the stile body 431.

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

[0038] The protrusion body 4321 is formed integrally with the frame body 431. The protrusion body 4321 is formed in a rectangular shape that is long in the projection direction and has a hollow portion 4321a inside. The protrusion body 4321 protrudes further toward the panel 45 than the frame 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 provided on the resin cover 4322 at intervals to completely cover the entire surface. The resin cover 4322 has an inner visible wall portion 4322a and an outer visible wall portion 4322b arranged to cover the left and right visible surfaces of the protrusion main body 4321, and an indoor visible wall portion 4322c arranged to cover the indoor visible surface of the protrusion main body 4321. The inner visible wall portion 4322a and the outer visible wall portion 4322b are arranged parallel to each other and extend in the visible direction. The resin cover 4322 is attached to the outer surface of the protrusion main body 4321 via the multiple ribs 4322d. This forms multiple hollow portions 4322e separated by the ribs 4322d 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 outer side X1 of the outer projection wall portion 4322b approximately coincides with the position of the surface of the indoor side X2 of the face material 45. An indoor side protruding piece 4323 extending in the projection direction toward the first shoji screen 3 is integrally formed at the end of the outer side X1 of the outer projection wall portion 4322b. The amount of protrusion in the projection direction of the indoor side protruding piece 4323 is equal to the amount of protrusion in the projection direction of the outdoor side protruding piece 4311. When the first shoji screen 3 and the second shoji screen 4 are closed, the indoor side protruding piece 4323 is positioned so as to overlap the outdoor side X1 of the indoor side protruding piece 3323 of the first shoji screen 3. As a result, the indoor side protruding piece 4323 comes into contact with the indoor side fin member 3324, forming an airtight portion on the indoor side X2 of the frame main body portion 431.

[0041] The indoor-side visible wall portion 4322c has a width sufficient to cover the stile main body portion 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 stile main body portion 431 and the spacer 451 from the indoor side X2, improving the design and insulation of the door edge 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 frame main 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 inner protruding wall portion 4331 and an outer protruding wall portion 4332 that form left and right protruding surfaces, and an exterior sight wall portion 4333 that faces the exterior side X1. The inner protruding wall portion 4331 and the outer protruding 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 side protruding surface of the interior protruding portion 432. The inner protruding wall portion 4331 and the outer protruding wall portion 4332 of the exterior protruding portion 433 are arranged on approximately the same plane along the protruding direction as the inner protruding wall portion 4322a and the outer protruding wall portion 4322b of the resin cover 4322 of the interior protruding portion 432.

[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 the indoor side X2 of the engagement grooves, similar to the outdoor protrusion 333 of the first shoji screen 3 shown in Figure 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 also 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 and W1b of the leading edge stiles 33 and 43 are smaller than half the widths W2 and W3 of the joints 11 and 12. Therefore, when the first and second shoji screens 3 and 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 handhold space for inserting fingers when opening and closing the first and second shoji screens 3 and 4. This improves the operability of the first and second shoji screens 3 and 4. The formation of the gap S between the leading edge stiles 33 and 43 eliminates the risk of fingers getting pinched between the leading edge stiles 33 and 43 when closing the first and second shoji screens 3 and 4.

[0048] Next, the configuration of the joint 11 will be described 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 vertical frame 34 of the first shoji screen 3 is composed of a metal trailing edge vertical frame main body 341 and a resin cover 342 provided to cover the outer surface of the trailing edge 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 side 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 side X2 of the first hollow portion 341a and protrudes further toward the room side 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 trailing edge side vertical frame body 341, the outdoor side sight wall portion 341d located on the outdoor side X1 of the first hollow portion 341a and the indoor side 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 of the trailing edge side vertical frame body 341.

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

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

[0054] The resin cover 342 is attached with a gap to cover the recessed surface and the visible surface on the interior side of the trailing edge side stile body 341. The resin cover 342 has an inner recessed wall portion 342a and an outer recessed wall portion 342b arranged to cover the left and right recessed surfaces of the trailing edge side stile body 341, and an interior side recessed wall portion 342c arranged to cover the visible surface on the interior side of the trailing edge side stile 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 indoor side X2, sandwiching and supporting the surface material 35 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 indoor 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 indoor side X2. Because the trailing edge stile main body 341 and the spacer 351 are difficult to see from the indoor side X2, the design and insulation of the trailing edge side of the first shoji screen 3 are improved.

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

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

[0058] A support piece 5411 protrudes from the end of the trailing edge vertical stile body 541 on the outdoor side X1 in the find direction toward the door tip (left side in Figure 5) beyond the hollow portion 541a. The support piece 5411 abuts against the trailing edge 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 on the end of the room side X2 of the trailing edge side vertical stile body 541. When the first shoji screen 3 and the third shoji screen 5 are closed, the protruding piece 5412 is inserted into a recessed groove 3412 provided on the room side 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 room side X2 is attached to the end of the trailing edge side stile body 541 on the room side X2, further outward in the viewing direction (to the right in Figure 5) than 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 body 541 on the indoor side X2. The resin cover 542 abuts against the trailing edge side grating channel 552 of the third shoji screen 5 from the indoor side X2, and supports the face material 55 by sandwiching it between the support piece 5411 and the resin cover 542. The resin cover 542 covers the spacer 551 of the face material 55 from the indoor side X2. Because the spacer 351 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 stile 34 of the first shoji screen 3. The width of the trailing edge vertical stile 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 of the room with the first shoji screen 3 and the third shoji screen 5 closed, the trailing edge vertical stile 54 of the third shoji screen 5 is completely hidden by the exterior side X1 of the trailing edge vertical stile 34 of the first shoji screen 3.

[0063] Next, the structure of the joint 12 will be described 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-to-rear 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 vertical frame 44 of the second shoji screen 4 is composed of a metal trailing edge vertical frame main body 441 and a resin cover 442 provided to cover the outer surface of the trailing edge 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 side 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 side X2 of the first hollow portion 441a and protrudes further toward the room side 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 trailing edge side vertical frame body 441, the outdoor side sight wall portion 441d located on the outdoor side X1 of the first hollow portion 441a and the indoor side 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 of the trailing edge side vertical frame body 441.

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

[0068] A groove 4412 is formed on the exterior 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 leading edge side (left side in FIG. 6 ) toward the trailing edge side (right side in FIG. 6 ) along the support piece 4411. The groove 4412 has a shape that opens toward the leading edge side.

[0069] The resin cover 442 is attached with a gap to cover the recessed surface and the visible surface on the interior side of the trailing edge side stile body 441. The resin cover 442 has an inner recessed wall portion 442a and an outer recessed wall portion 442b arranged to cover the left and right recessed surfaces of the trailing edge side stile body 441, and an interior side recessed wall portion 442c arranged to cover the visible surface on the interior side of the trailing edge side stile 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 grating channel 452 from the indoor side X2, sandwiching and supporting the surface material 45 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 stile main body 441. The indoor projection wall 442c has a width sufficient to cover the trailing edge stile main body 441 and the spacer 451 of the surface material 45 from the indoor side X2. Because the trailing edge 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 vertical frame 64 of the fourth shoji screen 6 is composed of a metal trailing edge vertical frame main body 641 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. A hollow portion 641a is provided inside the trailing edge side stile body 641.

[0073] A support piece 6411 protrudes from the end of the trailing edge vertical stile body 641 on the outdoor side X1 in the find direction toward the door tip (right side in Figure 6) beyond the hollow portion 641a. The support piece 6411 abuts against the trailing edge 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 on the end of the room-side X2 side of the trailing edge 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-side X1 side of the trailing edge vertical stile 44 of the second shoji screen 4, thereby forming a labyrinth structure.

[0075] An elastic fin member 6413 that protrudes toward the room side X2 is attached to the end of the trailing edge side stile body 641 on the room side X2, further outward in the viewing direction (to the left in Figure 6) than the protrusion 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 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 support piece 6411 and the resin cover 642. 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 stile 44 of the second shoji screen 4. The width of the trailing edge vertical stile 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 stile 64 of the fourth shoji screen 6 is completely hidden by the exterior side X1 of the trailing edge vertical stile 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 stile 33 of the first shoji screen 3, the leading edge stile 43 of the second shoji screen 4, the trailing edge stile 54 of the third shoji screen 5, and the trailing edge stile 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] 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 extending horizontally, a front-end vertical frame 73 extending vertically on the front end side (right side in Fig. 2), and a rear-end vertical frame 74 extending vertically on the rear end side (left side in Fig. 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 of the first screen door 7 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 stile 73 of the first screen door 7 is provided with a buffer member 731 that protrudes toward the indoor side X2. The buffer member 731 is made of, for example, mohair or packing. The buffer member 731 is located at the end of the leading edge stile 73 on the outside in the facing direction (the right side in Figure 4). The buffer member 731 abuts against the outdoor side facing wall 3333 that forms the outdoor facing surface of the leading edge stile 33 of the first shoji screen 3 from the outdoor side X1.

[0083] As shown in Figure 5, the trailing edge stile 74 of the first screen door 7 is provided with a buffer member 741 that protrudes toward the interior side X2. The buffer member 741 is made of mohair or packing, for example. The buffer member 741 is located at the end of the trailing edge stile 74 on the outside in the front view direction (the left side in Figure 5). The buffer member 741 abuts against the trailing edge stile 54 of the third shoji screen 5 from the exterior side X1. More specifically, the buffer member 741 abuts against the exterior side visible wall portion 5414 of the trailing edge stile main body 541, which forms the exterior-facing surface of the trailing edge stile 54, or against the support piece 5411 that is continuous with the exterior side visible wall portion 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) extending horizontally, a leading edge vertical frame 83 extending vertically on the leading edge side (left side in Fig. 2), and a trailing edge vertical frame 84 extending vertically on the trailing edge side (right side in Fig. 2). The leading edge vertical frame 83 of the second screen door 8 is the leading edge vertical frame for the second screen door, and the trailing edge vertical frame 84 is the trailing edge 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 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 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 of the second screen door 8 is positioned on the outside side X1 of the trailing edge vertical frame 64 of the fourth shoji screen 6.

[0086] As shown in Figure 4, the leading edge stile 83 of the second screen door 8 is provided with a buffer member 831 that protrudes toward the indoor side X2. The buffer member 831 is made of, for example, mohair or packing. The buffer member 831 is located at the end of the leading edge stile 83 on the outside in the facing direction (the left side in Figure 4). The buffer member 831 abuts against the outdoor side facing wall 4333 that forms the outdoor facing surface of the leading edge stile 43 of the second shoji screen 4 from the outdoor side X1.

[0087] As shown in Figure 6, the trailing edge stile 84 of the second screen door 8 is provided with a buffer member 841 that protrudes toward the interior side X2. The buffer member 841 is made of mohair or packing, for example. The buffer member 841 is located at the end of the trailing edge stile 84 on the outside in the front view direction (the right side in Figure 6). The buffer member 841 abuts against the trailing edge stile 64 of the fourth shoji screen 6 from the exterior side X1. More specifically, the buffer member 841 abuts against the exterior side visible wall portion 6414 of the trailing edge stile main body 641, which forms the exterior-facing surface of the trailing edge stile 64, or against a support piece 6411 that is continuous with the exterior side visible wall portion 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] Figure 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 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 Figure 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 exterior side 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 exterior side X1. This allows the gap between the first shoji screen 3 and the second shoji screen 4 to be shielded only by 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, the first screen door 7 can be arranged apart from the second screen door 8.

[0090] 8 to 12 show butt joints 10A to 10E according to other embodiments. Since the same reference numerals as those in the butt joint 10 indicate parts with the same configuration, their descriptions will be omitted below and the description of the butt joint 10 will be used. The first screen door 7 and the second screen door 8 are not shown in FIGS. 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 leading-side 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, allowing for a larger space for handles to be formed 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 outdoor protrusions 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 3337, 4337 are formed over the entire length of the outdoor protrusions 333, 433. The handles 3337, 4337 are formed by recessing the outdoor-side X1 end of the inner projection wall 3331, 4331 of the outdoor protrusion 333, 433 toward the outer projection wall 3332, 4332. The width of the outdoor projection wall 3333, 433 of the outdoor protrusion 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 10B when viewed from the outside surface X1 from the butt joint 10.

[0093] At the butt joint 10B, there is no gap between the indoor-side protrusions 332, 432 of the door-end vertical stiles 33, 43. The indoor-side X2 ends of the indoor-side protrusions 332, 432 are formed to abut each other. Specifically, the indoor-side X2 ends of the protrusion bodies 3321, 4321 of the indoor-side protrusions 332, 432 and the resin covers 3322, 4322 extend out in a rectangular shape in the forward direction so as to abut against each other and abut each other. This means that no gaps are 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 positioning the outdoor protruding wall portions 3333, 4333 of the outdoor protruding portions 333, 433 closer to the indoor side X2 than the outdoor side X1 ends of the inner protruding wall portions 3331, 4331 and the outer protruding wall portions 3332, 4332.

[0095] Hollow exterior elastic members 3339, 4339 are attached to the exterior-side X1 ends of the exterior projection walls 3332, 4332 of the exterior projections 333, 433, respectively, to close the gap S on the exterior side X1. The exterior elastic members 3339, 4339 are formed symmetrically from an elastic material such as rubber. The exterior elastic members 3339, 4339 are formed along the entire length of the exterior projections 333, 433, protrude in the front direction, and contact each other. This further improves the airtightness of the exterior side X1 of the butt joint 10C. Even if a finger is pinched between the leading vertical stiles 33, 43 on the exterior side X1 when closing the first and second shoji screens 3 and 4, the exterior elastic members 3339, 4339 elastically flex, minimizing pain.

[0096] Hollow indoor-side elastic members 3325, 4325 that close the gap S on the indoor side X2 are attached to the indoor-side protrusions 332, 432 of the door-end-side vertical stiles 33, 43 of the butt joint 10C. The indoor-side elastic members 3325, 4325 are formed symmetrically from an elastic material such as rubber. The indoor-side elastic members 3325, 4325 are formed over the entire length of the indoor-side protrusions 332, 432, protrude in the viewing direction, and are in contact with each other. The indoor-side elastic members 3325, 4325 are attached to the protrusion bodies 3321, 4321 of the indoor-side protrusions 332, 432. The resin covers 3322, 4322 of the indoor-side protrusions 332, 432 are divided into a first cover portion 3322A, 4322A and a second cover portion 3322B, 4322B, with an indoor-side elastic member 3325, 4325 sandwiched between them. This further improves the airtightness of the indoor side X2 of the butt joint 10C. Even if a finger is pinched between the leading vertical stiles 33, 43 on the indoor side X2 when closing the first shoji screen 3 and the second shoji screen 4, the indoor-side elastic member 3325, 4325 elastically bends, so pain is less likely to be inflicted.

[0097] The butt joint 10D shown in Figure 11 has the outdoor-side elastic members 3339, 4339 of the butt joint 10C shown in Figure 10 attached to the outdoor-side protrusions 333, 433 of the leading-side stiles 33, 43 of the butt joint 10B shown in Figure 9. A hollow indoor-side elastic member 4326 that seals the gap S on the indoor side X2 is attached to the indoor-side protrusion 432 of the leading-side stile 43 of the butt joint 10D. The indoor-side elastic member 4326 is formed from an elastic material such as rubber. The indoor-side elastic member 4326 is formed over the entire length of the indoor-side protrusion 432, protrudes in the direction of view, and contacts the indoor-side protrusion 332 of the leading-side stile 33. The resin cover 4322 of the indoor side protruding portion 432 is divided into two parts, a first cover part 4322A and a second cover part 4322B, with an indoor side elastic member 4326 sandwiched between them. The indoor side elastic member 4326 is arranged on the indoor side protruding portion 332 side of the door end side vertical frame 33, and may be provided so as to come into contact with the indoor side protruding portion 432 of the door end side vertical frame 43.

[0098] The abutment 10E shown in Fig. 12 further has an airtight structure in the stile body portions 331, 431 of the leading edge stiles 33, 43 in the abutment 10 shown in Fig. 4. More specifically, the stile body portion 331 of the leading edge stile 33 of the first shoji screen 3 has a protruding piece 3313 extending in the front direction toward the second shoji screen 4 over the entire length of the leading edge stile 33. The stile body portion 431 of the leading edge stile 43 of the second shoji screen 4 has an exterior protruding piece 4312 and an interior protruding piece 4313 formed over the entire length of the leading edge stile 33. The exterior protruding piece 4312 and the interior protruding piece 4313 extend in the front direction toward the first shoji screen 3. The exterior protruding piece 4312 is positioned on the exterior side X1 relative to the protruding piece 3313 of the first shoji screen 3, and the interior protruding piece 4313 is positioned on the interior side X2 relative to the protruding piece 3313 of the first shoji screen 3. The protruding piece 3313, the exterior protruding piece 4312, and the interior protruding piece 4313 each protrude in the front view direction so as to overlap in the front view direction when the first shoji screen 3 and the second shoji screen 4 are closed.

[0099] An elastic fin member 4314 that protrudes toward the inside X2 side is attached to the surface of the outside projection piece 4312 on the inside X2 side. The fin member 4314 contacts the projection piece 3313 of the first shoji screen 3 from the outside X1 side.

[0100] The frame body 431 is further provided with a block-shaped airtight material 4315. The airtight material 4315 is attached between the exterior protruding piece 4312 and the interior protruding piece 4313. A groove 4315a is formed on the inner surface of the airtight material 4315 to accommodate the protruding piece 3313 of the first shoji screen 3.

[0101] By providing such an airtight structure in the butt joint 10E, the airtightness of the butt joint 10E is further improved. The butt joint 10E has a structure in which the protruding piece 3313, the outdoor protruding piece 4312, and the indoor protruding piece 4313 are arranged to overlap in the projection direction, and the protruding piece 3313 is accommodated in the groove 4315a of the airtight material 4315, so that the first shoji screen 3 and the second shoji screen 4 can be prevented from moving in the projection direction. This further improves the wind pressure resistance of the first shoji screen 3 and the second shoji screen 4. This airtight structure can also be applied to the butt joints 10, 10A to 10D.

[0102] As explained above, the fitting 1 of this embodiment is provided with the first shoji screen 3 and the second shoji screen 4 that slide on the indoor rails 211, 221 that extend along the length direction of the horizontal frames (upper horizontal frame 21, lower horizontal frame 22). The first shoji screen 3 has a first leading edge vertical frame 33 and a first trailing edge vertical frame 34, and the second shoji screen 4 has a second leading edge vertical frame 43 and a second trailing edge vertical frame 45. 44, and when the first shoji screen 3 and the second shoji screen 4 are closed, the first leading edge vertical frame 33 and the second leading edge vertical frame 43 are butted together, and the overall width of the first leading edge vertical frame 33 and the second leading edge vertical frame 43 in the butted together state is equal to the width of each of the first trailing edge vertical frame 34 and the second trailing edge vertical frame 44.

[0103] This eliminates the need to configure the leading edge vertical frame of one shoji screen to cover and swallow up the visible surface of the leading edge vertical frame of the other shoji screen on the interior side, and allows the widths of the leading edge and trailing edge vertical frames of the two shoji screens, the first and second shoji screens, to be unified, thereby improving the design.

[0104] In the building fixture 1 of this embodiment, the width of each of the first door-end side vertical frame 33 and the second door-end side vertical frame 43 is less than half the width of each of the first door-end side vertical frame 34 and the second door-end side vertical frame 44.

[0105] This makes it possible to easily unify the overall width of the first door-end side vertical frame 33 and the second door-end side vertical frame 43 when they are butted together to the respective widths of the first door-end side vertical frame 34 and the second door-end side vertical frame 44.

[0106] In the building fixture 1 of this embodiment, the first door-end side vertical frame 33 and the second door-end side vertical frame 43 each have an indoor-side protruding portion 332, 432 that protrudes toward the indoor side X2, and a gap S for a handle is formed between the indoor-side protruding portions 332, 432 of the first door-end side vertical frame 33 and the second door-end side vertical frame 43 when they are butted together.

[0107] This improves the operability of the first shoji screen 3 and the second shoji screen 4. When closing the first shoji screen 3 and the second shoji screen 4, there is no risk of fingers getting caught between the door-end vertical frames 33, 43.

[0108] In the building fixture 1 of this embodiment, elastic members (indoor elastic members 3325, 4325, 4326) are provided between the indoor protrusions 332, 432 of the first door-end vertical frame 33 and the second door-end vertical frame 43, which are butted together, to close the gap S.

[0109] This further improves the airtightness of the indoor side X2 between the first leading edge vertical frame 33 and the second leading edge vertical frame 43. Even if a finger is pinched when closing the first shoji screen 3 and the second shoji screen 4, the indoor side elastic members 3325, 4325 bend elastically, so that the finger is less likely to be hurt.

[0110] In the building fixture 1 of this embodiment, the first door-end side vertical frame 33 and the second door-end side vertical frame 43 each have outdoor protrusions 333, 433 that protrude to the outside of the room, and handles 3336, 3337, 3338, 4336, 4337, 4338 are formed on the outdoor protrusions 333, 433 of the first door-end side vertical frame 33 and the second door-end side vertical frame 43, respectively.

[0111] This improves the operability of the first shoji screen 3 and the second shoji screen 4 on the outside side X1.

[0112] The fitting 1 of this embodiment further includes a third shoji screen 5 and a fourth shoji screen 6 that slide on outdoor rails 212, 222 that extend along the length of the horizontal frames (upper horizontal frame 21, lower horizontal frame 22). The third shoji screen 5 has a third leading edge vertical frame 53 and a third trailing edge vertical frame 54. The fourth shoji screen 6 has a fourth leading edge vertical frame 63 and a fourth trailing edge vertical frame 64. The third trailing edge vertical frame 54 is arranged to overlap the outdoor side X1 of the first trailing edge vertical frame 34 of the first shoji screen 3 in the closed state. The trailing edge vertical frame 64 of No. 4 is positioned so as to overlap the outside side X1 of the second trailing edge vertical frame 44 of the second shoji screen 4 in the closed state, and the outside facing surfaces (outside facing wall portions 3333, 4333) of the outside protrusions 333, 433 of the first leading edge vertical frame 33 and the second leading edge vertical frame 43 are positioned at the same position in the facing direction as the outside facing surfaces (outside facing wall portions 5414, 6414) of the third trailing edge vertical frame 54 of the third shoji screen 5 and the fourth trailing edge vertical frame 64 of the fourth shoji screen 6.

[0113] This allows the exterior facing surfaces of the shoji screens 3 to 6 to be aligned, improving the design. If a screen door is provided on the exterior side, it can be positioned optimally. The exterior facing surfaces of the first leading edge vertical frame 33 of the first shoji screen 3 and the second leading edge vertical frame 43 of the second shoji screen 4 are positioned at the same position in the forward direction as the exterior facing surfaces of the third trailing edge vertical frame 54 of the third shoji screen 5 and the fourth trailing edge vertical frame 64 of the fourth shoji screen 6. This means that the first leading edge vertical frame 33 of the first shoji screen 3 and the second leading edge vertical frame 43 of the second shoji screen 4 straddle the exterior rails 212, 222, thereby improving the wind pressure resistance of the first shoji screen 3 and the second shoji screen 4 even if the first leading edge vertical frame 33 and the second leading edge vertical frame 43 are each thinner than the other frames.

[0114] In the fitting 1 of this embodiment, the third shoji screen 5 and the fourth shoji screen 6 slide on the outdoor rails 212, 222 extending along the length direction of the horizontal frames (upper horizontal frame 21, lower horizontal frame 22), and the screen door (first screen door) is arranged on the outdoor side X1 of the outdoor rails 212, 222 and slides on the screen door rails 213, 223 extending along the length direction of the horizontal frames (upper horizontal frame 21, lower horizontal frame 22). The third shoji screen 5 has a third leading edge side stile 53 and a third trailing edge side stile 54, and the fourth shoji screen 6 has a fourth leading edge side stile 63 and a fourth trailing edge side stile 64, and the third trailing edge side stile 54 is arranged to overlap the outside side X1 of the first trailing edge side stile 34 of the first shoji screen 3 in the closed state, and the fourth trailing edge side stile 64 is arranged to overlap the outside side X1 of the first trailing edge side stile 34 of the second shoji screen 3 in the closed state. The exterior facing surfaces (outdoor facing wall portions 5414, 5415) of the exterior protrusions 333, 433 of the first leading-edge stile 33 and the second leading-edge stile 43 of the fourth shoji screen 6 are arranged to overlap the exterior facing surface X1 of the second trailing-edge stile 44 of the third shoji screen 5, and the .... 14), the screen door (first screen door 7 or second screen door 8) is arranged at the same position in the front direction, and is provided between the outdoor protruding portion 333 of the first leading edge vertical frame 33 of the first shoji screen 3 in the closed state and the fourth trailing edge vertical frame 64 of the fourth shoji screen 6, or between the outdoor protruding portion 433 of the second leading edge vertical frame 43 of the second shoji screen 4 and the third trailing edge vertical frame 54 of the third shoji screen 5.

[0115] According to this, even if either the first shoji screen 3 or the second shoji screen 4 is opened, the space between the opened first shoji screen 3 and the second shoji screen 4 can be shielded by only one screen door (the first screen door 7 or the second screen door 8).

[0116] In the building fixture 1 of this embodiment, the screen door has a first screen door 7 and a second screen door 8 that slide on common screen door rails 213, 223, and buffer members 731, 831 are provided between the first leading edge vertical frame 33 of the first shoji screen 3 and the leading edge vertical frame 73 of the first screen door 7, and between the second leading edge vertical frame 43 of the second shoji screen 4 and the leading edge vertical frame 83 of the second screen door 8.

[0117] This prevents dust, insects, etc. from entering the room side X2 through the gap between the leading vertical frames 73, 83 of the first and second screen doors 7, 8 and the leading vertical frames 33, 43 of the first and second shoji screens 3, 4.

[0118] While one preferred embodiment of the fitting 1 of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate. For example, the gap S on the exterior side X1 of the butt joint 10 does not have to be formed. The butt joint 10 does not have to have a gap S on both the exterior side X1 and the interior side X2. A handle similar to the handles 3336, 3337, 3338, 4336, 4337, 4338 provided on the exterior side X1 of the butt joint 10 may be provided on the interior side X2. The butt joint 10 may be provided with only one of the interior elastic members 3325, 4325, 4326 and the exterior elastic members 3339, 4339.

[0119] The buffer members 731, 741 provided on the leading edge vertical stile 73 and trailing edge vertical stile 74 of the first screen door 7 are not limited to those provided on the first screen door 7. The buffer members 731, 741 may be provided on the outdoor facing surface (outdoor facing wall portion 3333) of the first leading edge vertical stile 33 of the first shoji screen 3, and on the outdoor facing surface (outdoor facing wall portion 5414) of the third trailing edge vertical stile 54 of the third shoji screen 5. Similarly, the cushioning members 831, 841 provided on the leading edge vertical frame 83 and trailing edge vertical frame 84 of the second screen door 8 may also be provided on the outdoor facing surface (outdoor facing wall portion 4333) of the second trailing edge vertical frame 44 of the second shoji screen 4, and on the outdoor facing surface (outdoor facing wall portion 6414) of the fourth trailing edge vertical frame 64 of the fourth shoji screen 6.

[0136] Next, with reference to Figures 14 and 15, the specific configuration of the leading edge stile 33A of the first shoji screen 3 will be described. The leading edge stile 33A of the first shoji screen 3 is formed to protrude toward the exterior side X1. Specifically, the leading edge stile 33A protrudes substantially vertically toward the exterior side X1 and integrally includes a stile covering portion 334 that is displaced toward the second shoji screen 4 (the right side in Figure 14) and is shaped to encompass the leading edge of the second shoji screen 4 from the exterior side X1. In other words, the leading edge stile 33A is positioned to cover the leading edge of the second shoji screen 4 from the exterior side X1. The stile covering portion 334 extends along the length of the leading edge stile 33A and completely covers the exterior side X1 facing surface 43a of the leading edge stile 43A of the second shoji screen 4. As a result, when the fitting 1A is observed from the outside X1, the width of the butt joint 10 is essentially narrow, covering only the visible surface 33a on the outside X1 of the vertical frame 33A (frame covering portion 334) on the door end side of the first shoji screen 3, thereby improving the design of the fitting 1A.

[0137] The trailing edge stile 34 of the first shoji screen 3 is formed in a shape that protrudes toward the room side X2. Specifically, the trailing edge stile 34 protrudes in a substantially vertical direction toward the room side X2, opposite to the leading edge stile 33A. The trailing edge stile 34 is positioned so as to overlap the trailing edge stile 54 of the third shoji screen 5 in the projection direction, thereby concealing the trailing edge stile 54 of the third shoji screen 5 from the room side X2.

[0138] The leading edge stile 43A of the second shoji screen 4 is formed in a shape that protrudes toward the room's interior side X2, opposite to the leading edge stile 33A of the first shoji screen 3. Specifically, the leading edge stile 43A protrudes so as to protrude in a substantially vertical direction toward the room's interior side X2. The protruding portion of the leading edge stile 43A on the room's interior side X2 is displaced toward the first shoji screen 3 (left side in FIG. 14 ) so as to cover the visible surface 33b on the room's interior side X2 of the leading edge stile 33A of the first shoji screen 3, and is formed in a shape that swallows the leading edge of the first shoji screen 3 from the room's interior side X2. In other words, the leading edge stile 43A is positioned to cover the leading edge of the first shoji screen 3 from the room's interior side X2.

[0139] Like the leading edge stile 43A, the trailing edge stile 44 of the second shoji screen 4 is also formed in a shape that protrudes toward the room side X2. Specifically, the trailing edge stile 44 protrudes so as to protrude in a substantially vertical direction toward the room side X2. The trailing edge stile 44 is positioned so as to overlap the trailing edge stile 64 of the fourth shoji screen 6 in the front direction, thereby obscuring the trailing edge stile 64 of the fourth shoji screen 6 from the room side X2.

[0140] In the leading edge vertical frame 33A of the first shoji screen 3, the frame covering portion 334 extends beyond the outdoor rails 212, 222 toward the outdoor side X1. As shown in Figure 15, both the upper and lower ends of the frame covering portion 334 have height extensions 3341, 3342 that are positioned to straddle the outdoor rails 212, 222.

[0141] The extension 3341 at the upper end of the frame covering portion 334 extends further upward than the lower end 212a of the outdoor rail 212 attached to the upper horizontal frame 21. The extension 3341 has an outdoor extension 3341a arranged on the outdoor side X1 of the outdoor rail 212, and an indoor extension 3341b arranged on the indoor side X2 of the outdoor rail 212. The extension 3341 has a groove 3341c with a generally U-shaped or C-shaped cross section between the outdoor extension 3341a and the indoor extension 3341b. The groove 3341c accommodates the lower end 212a of the outdoor rail 212 so as to sandwich it from the outdoor side X1 and the indoor side X2.

[0142] The extension 3342 on the lower side of the frame covering portion 334 extends further downward than the upper end 222a of the outdoor rail 222 attached to the lower horizontal frame 22. The extension 3342 has an outdoor extension 3342a arranged on the outdoor side X1 of the outdoor rail 222 and an indoor extension 3342b arranged on the indoor side X2 of the outdoor rail 222. The extension 3342 has a groove 3342c with a generally U-shaped or C-shaped cross section between the outdoor extension 3342a and the indoor extension 3342b. The groove 3342c accommodates the upper end 222a of the outdoor rail 222 so that it is sandwiched between the outdoor side X1 and the indoor side X2 by the outdoor extension 3342a and the indoor extension 3342b.

[0143] When the first shoji screen 3 receives wind pressure, the extensions 3341, 3342 of the stile covering portion 334 of the door-end vertical stile 33A come into contact with and engage the outdoor rails 212, 222. This increases the attachment strength of the first shoji screen 3 in the projection direction (indoor-outdoor direction, left-right direction in FIG. 15 ) to the frame body 2. Specifically, when the first shoji screen 3 receives wind pressure (positive pressure) from the outdoor side X1 to the indoor side X2, the first shoji screen 3 is slightly displaced toward the indoor side X2, causing the outdoor extensions 3341a, 3342a of the extensions 3341, 3342 to come into contact with and engage the outdoor rails 212, 222, thereby functioning to receive the wind pressure. When the first shoji screen 3 receives wind pressure (negative pressure) from the indoor side X2 toward the outdoor side X1, the first shoji screen 3 is slightly displaced toward the outdoor side X1, causing the indoor extensions 3341b, 3342b of the extensions 3341, 3342 to come into contact with and engage with the outdoor rails 212, 222, thereby functioning to receive the wind pressure. Therefore, the first shoji screen 3 can improve its wind pressure resistance performance against both positive and negative wind pressure.

[0144] When the first shoji screen 3 and the second shoji screen 4 are configured to butt together in the center of the fitting 1A, the attachment strength of the first shoji screen 3 to the frame 2 in the forward direction is increased, and as a result, the first shoji screen 3 can supplement the attachment strength of the second shoji screen 4 to the frame 2 in the forward direction. This improves the wind pressure resistance of the fitting 1A as a whole.

[0145] 15, the grooves 3341c and 3342c of the extensions 3341 and 3342 are not in contact with the outdoor rails 212 and 222. Therefore, the extensions 3341 and 3342 do not affect the sliding movement of the first shoji screen 3.

[0146] In the above embodiment, the first shoji screen 3 slides on the indoor rails 211, 221, and the stile covering portion 334 of the leading edge vertical stile 33A is arranged to straddle the outdoor rails 212, 222, but this is not limiting. The first shoji screen 3 and the second shoji screen 4 may slide on the outdoor rails 212, 222, and the third shoji screen 5 and the fourth shoji screen 6 may slide on the indoor rails 211, 221. In this case, the stile covering portion 334 of the leading edge vertical stile 33A of the first shoji screen 3, which has the extensions 3341, 3342, protrudes toward the indoor side X2 and is arranged to straddle the indoor rails 211, 221.

[0147] The frame covering portion 334 may have only one of the upper extension portion 3341 and the lower extension portion 3342. The frame covering portion having an extension portion is not limited to being provided on the leading edge vertical frame of the shoji screen, but may also be provided on the trailing edge vertical frame, or may be provided on both the leading edge vertical frame and the trailing edge vertical frame.

[0148] As described above, the building fixture 1A of this embodiment has indoor rails 211, 221 and outdoor rails 212, 222 that extend along the length of the horizontal frames (upper horizontal frame 21, lower horizontal frame 22), and is equipped with a shoji screen (first shoji screen 3) that slides along one of the indoor rails 211, 221 and the outdoor rails 212, 222 (indoor rails 211, 221), and the vertical frame (door-end vertical frame 33A) of the shoji screen (first shoji screen 3) extends beyond the other rail (outdoor rails 212, 222) of the indoor rails 211, 221 and the outdoor rails 212, 222, and has extensions 3341, 3342 that extend vertically so as to straddle the other rail (outdoor rail 212, 222).

[0149] This improves the wind pressure resistance of the shoji screen (first shoji screen 3) that slides along either the indoor rails 211, 221 or the outdoor rails 212, 222 (indoor rails 211, 221).

[0150] The fixture 1A of this embodiment has a first shoji screen 3 and a second shoji screen 4 that slide on the same rail (indoor rail 211, 221), either the indoor rail 211, 221 or the outdoor rail 212, 222, and is configured so that the leading edge vertical frames 33A, 43A of the first shoji screen 3 and the second shoji screen 4 are abutted against each other when closed, and the leading edge vertical frame 33A of the first shoji screen 3 extends beyond the other rail (outdoor rail 212, 222) and has a frame covering portion 334 that is arranged to cover the visible surface (outdoor side X1 visible surface 43a) of the leading edge vertical frame 43A of the second shoji screen 4 when the first shoji screen 3 and the second shoji screen 4 are closed, and extension portions 3341, 3342 are provided on the frame covering portion 334.

[0151] This improves the wind pressure resistance of the first shoji screen 3 and the second shoji screen 4, which slide along either the indoor rail 211, 221 or the outdoor rail 212, 222 (indoor rail 211, 221).

[0152] In the fixture 1A of this embodiment, the first shoji screen 3 and the second shoji screen 4 slide on the indoor rails 211, 221, and the extensions 3341, 3342 of the frame covering portion 334 are positioned so as to straddle the outdoor rails 212, 222.

[0153] As a result, the frame covering portion 334 does not protrude toward the indoor side X2, so the design of the fitting 1A is not impaired when viewed from the indoor side X2.

[0154] The building fixture of the present disclosure includes the following aspects.

[0155] <Aspect A1> A fitting having an indoor rail and an outdoor rail extending parallel to the length of a horizontal frame, and a shoji screen that slides along one of the indoor rail and the outdoor rail, wherein the vertical frame of the shoji screen extends beyond the other of the indoor rail and the outdoor rail, and has an extension that extends in the height direction so as to straddle the other rail.

[0156] <Aspect A2> A fitting according to aspect A1, comprising a first shoji screen and a second shoji screen that slide on the same rail, either the indoor rail or the outdoor rail, and configured so that the butt frames of the first shoji screen and the second shoji screen are butted together when closed, the butt frame of the first shoji screen extends beyond the other rail and has a frame covering part that is arranged to cover the visible surface of the butt frame of the second shoji screen when the first shoji screen and the second shoji screen are closed, and the extension part is provided on the butt frame of the first shoji screen.

[0157] <Aspect A3> The fitting according to Aspect A2, wherein the first shoji screen and the second shoji screen slide on the indoor rail, and the extension portion is disposed so as to straddle the outdoor rail.

[0158] However, if the leading edge stile of one shoji door at the butt joint has a stile shape that covers and encloses the outside of the leading edge stile of the other shoji door, there is a risk of fingers getting pinched between the leading edge stiles when grasping the leading edge stile with one hand to open or close the door. Therefore, below, we will explain about a fitting 1B that can solve the problem of providing a fitting that does not have the risk of fingers getting pinched when opening or closing the door, even if the leading edge stile of one shoji door at the butt joint has a stile shape that covers and encloses the outside of the leading edge stile of the other shoji door.

[0159] Figures 16 to 19 show a fitting 1B according to yet another embodiment. The fitting 1B is a modified version of the fitting 1A described above. Figure 16 is a front view of the fitting 1B as seen from the inside X2 of the room. The fitting 1B is similar to the fittings 1 and 1A in that it is provided with a first shoji screen 3 and a second shoji screen 4 arranged on the inside X2 of the room, and a third shoji screen 5 and a fourth shoji screen 6 arranged on the outside X1 of the room, each of which can slide left and right inside the frame 2. Parts with the same reference numerals as the fittings 1 and 1A described above indicate components with the same functions, and therefore detailed descriptions of these parts will be cited from the descriptions of the fittings 1 and 1A, and may be omitted below.

[0160] Fig. 17 is a schematic diagram illustrating the opening and closing operation of the second shoji screen 4, showing the first shoji screen 3, the second shoji screen 4, the third shoji screen 5, and the fourth shoji screen 6 of the fitting 1B in a plan view. In Fig. 17, the illustration of the indoor and outdoor rails along which the shoji screens 3, 4, 5, and 6 slide is omitted.

[0161] The leading edge stile 33B of the first shoji screen 3 protrudes toward the outside X1 and is displaced toward the second shoji screen 4 (the right side in FIG. 17 ), forming a shape that accommodates and covers the leading edge of the second shoji screen 4 from the outside X1. The trailing edge stile 34 of the first shoji screen 3 protrudes toward the inside X2 and overlaps with the trailing edge stile 54 of the third shoji screen 5 in the front-to-back direction. The leading edge stile 43B of the second shoji screen 4 protrudes toward the inside X2 and is displaced toward the first shoji screen 3 (the left side in FIG. 17 ), forming a shape that accommodates and covers the leading edge of the first shoji screen 3 from the inside X2. The trailing edge stile 44 of the second shoji screen 4 protrudes toward the inside X2 and overlaps with the trailing edge stile 44 of the fourth shoji screen 6 in the front-to-back direction. In this fitting 1B, when the second shoji screen 4 is opened or closed from the inside X2 of the room, the operator grasps the vertical frame 43A on the door end side of the second shoji screen 4 that protrudes on the inside X2 of the room with his or her hand and slides it in the direction of the white arrow.

[0162] The specific configuration of the leading edge vertical frames 33, 43 of the first shoji screen 3 and the second shoji screen 4 of the fitting 1B will be described using Figures 18 and 19. Figures 18 and 19 are enlarged cross-sectional views showing the leading edge vertical frames 33B, 43B of the first shoji screen 3 and the second shoji screen 4 of the fitting 1B in the closed state. The first shoji screen 3 and the second shoji screen 4 are arranged to be slidable on the same indoor rails 211, 221, but only the indoor rail 221 of the lower horizontal frame 22 is shown in Figures 18 and 19.

[0163] In the fitting 1B, three glass plates G spaced apart by spacers 351 are housed inside the first shoji screen 3 via a gasket Ga as the face material 35. The leading edge vertical stile 33B of the first shoji screen 3 is extruded from a metal material such as aluminum, and has a stile covering portion 334 integral with the exterior side X1 of the stile main body 331. The stile main body 331 of the leading edge vertical stile 33B in the first shoji screen 3 of the fitting 1B covers the leading edge surface of the face material 35 and houses the leading edge side of the face material 35 by sandwiching the spacer 351 portion of the face material 35 from the exterior side X1 and the interior side X2. An extension piece 3314 that rises approximately vertically toward the second shoji screen 4 is integrally formed on the butt surface 331a, which is the front surface of the stile main body 331, at a position slightly toward the outside X1 from the center of the front direction. The extension piece 3314 extends along the length of the leading edge vertical stile 33B. A resin cover 335 is attached to the interior side X2 surface of the stile main body 331. The resin cover 335 forms the front surface 33b on the interior side X2 of the leading edge vertical stile 33, and covers the portion of the spacer 351 in the face material 35 from the interior side X2. Therefore, the leading edge vertical stile 33B of the first shoji screen 3 has excellent thermal insulation properties.

[0164] The stile covering portion 334 is formed along the length of the door-end side vertical stile 33B, protruding from the stile main body portion 331 toward the exterior side X1 and displacing toward the second shoji screen 4 (right side in FIG. 18 ), so as to encompass the door-end side of the second shoji screen 4 from the exterior side X1. In other words, the door-end side vertical stile 33B is positioned to cover the door-end side of the second shoji screen 4 from the exterior side X1. The stile covering portion 334 integrally includes a first wall portion 334a, a second wall portion 334b, a third wall portion 334c, and a fourth wall portion 334d. The cross section of the stile covering portion 334 is formed to be approximately rectangular, and includes a hollow portion 334e inside. The first wall portion 334a rises approximately vertically from the stile main body portion 331 toward the exterior side X1. The second wall portion 334b ​​extends from the end of the first wall portion 334a on the outside side X1 toward the second shoji screen 4. The third wall portion 334c extends from the end of the second wall portion 334b ​​on the second shoji screen 4 side toward the inside side X2, generally parallel to the first wall portion 334a. The fourth wall portion 334d extends from the end of the third wall portion 334c on the inside side X2 toward the frame main body portion 331, generally parallel to the second wall portion 334b.

[0165] The surface of the second wall portion 334b ​​forms the visible surface 33a on the outside X1 of the leading edge stile 33B. The second wall portion 334b ​​extends toward the second shoji screen 4 beyond the abutment surface 331a, and when the first shoji screen 3 and the second shoji screen 4 are abutted together, it entirely covers the visible surface 43a on the outside X1 of the leading edge stile 43B of the second shoji screen 4. The stile covering portion 334 covers the leading edge stile 43B of the second shoji screen 4 and the portion of the spacer 451 in the face material 45 from the outside X1. Therefore, when the fitting 1B is observed from the outside X1, the butt joint 10 appears to have a narrow width that is essentially the same as the width of the visible surface 33a of the vertical frame 33B on the door end side of the first shoji screen 3 (the width of the second wall portion 334b ​​of the frame covering portion 334), thereby providing excellent design.

[0166] The inside of the second shoji screen 4 also houses three glass panes G, spaced apart by spacers 451, via a gasket Ga, as face materials 45. The leading-edge vertical stile 43B of the second shoji screen 4 has a stile body 431 extruded from a metal material such as aluminum. The stile body 431 covers the leading-edge surface of the face material 45 and extends from the end of the exterior side X1 in the facing direction (left-right direction in Figure 18) to cover the spacer 451 of the face material 45 from the exterior side X1. The facing surface 43a of the leading-edge vertical stile 43B on the exterior side X1 has an extension 431b that extends toward the first shoji screen 3 beyond the butt surface 431a, which is the facing surface of the stile body 431. The extension 431b is arranged on the outdoor side X1 of the extension piece 3314 formed on the abutting surface 331a of the leading edge vertical frame 33B of the first shoji screen 3, and overlaps with the extension piece 3314 in the forward direction. The end of the frame main body 431 on the indoor side X2 has a standing wall 431c that extends parallel to the extension 431b toward the first shoji screen 3. The standing wall 431c is arranged on the indoor side X2 of the extension piece 3314 of the leading edge vertical frame 33B of the first shoji screen 3.

[0167] An airtight material 436 is attached to the surface of the extension 431b facing the indoor side X2. As shown in Figure 18, when the first shoji screen 3 and the second shoji screen 4 are butted together, the airtight material 436 comes into contact with the extension piece 3314 from the outdoor side X1, sealing the gap between the extension piece 3314. Furthermore, a guide block 9 is housed between the extension 431b and the vertical wall 431c. The airtight material 436 and the guide block 9 extend along the length of the door-end vertical stile 43B.

[0168] The door-end vertical stile 43B has a stile covering part 434 that protrudes toward the indoor side X2 at the indoor side X2 end of the stile main body 431 via a resin bridge part 435 for thermal insulation. The bridge part 435 is positioned so that it protrudes toward the indoor side X2 further than the position of the spacer 451 on the indoor side X2 furthest side of the face material 45 of the second shoji 4. The stile covering part 434 is composed of a stile covering part main body 4341 that is integrally extruded from a metal material such as aluminum, and a resin cover 4342 that covers the outer surface of the stile covering part main body 4341. The stile covering part main body 4341 is connected to the stile main body 431 by the bridge part 435. This prevents heat transfer between the metal frame main body 431 located on the outside side X1 and the metal frame covering body 4341 located on the inside side X2, giving the door end side vertical frame 43B high insulation properties.

[0169] The frame covering body 4341 is formed along the length of the door-end side vertical frame 43B, and extends from the frame body 431 toward the outside X1, displacing toward the first shoji screen 3 (the left side in FIG. 18 ) and shaped to encompass the door-end side of the first shoji screen 3 from the inside X2. In other words, the frame covering body 4341 is arranged to cover the door-end side of the first shoji screen 3 from the inside X2. The frame covering body 4341 integrally includes a first wall portion 4341a, a second wall portion 4341b, a third wall portion 4341c, a fourth wall portion 4341d, a fifth wall portion 4341e, and a connecting wall portion 4341f with the bridge portion 435, and has a hollow portion 4341g therein. The first wall portion 4341a rises substantially perpendicularly to the indoor side X2 surface of the face material 45 of the second shoji screen 4. The second wall portion 4341b extends from the indoor side X2 end of the first wall portion 4341a toward the first shoji screen 3. The third wall portion 4341c extends substantially parallel to the first wall portion 4341a from the end of the second wall portion 4341b facing the first shoji screen 3 toward the outdoor side X1. The outdoor side X1 end of the third wall portion 4341c is positioned closer to the indoor side X2 than the outdoor side X1 end of the first wall portion 4331a. The fourth wall portion 4341d extends substantially parallel to the second wall portion 4321b from the outdoor side X1 end of the third wall portion 4341c toward the first wall portion 4341a. The fifth wall 4341e extends from the end of the fourth wall 4341d on the second shoji screen 4 side to the outside X1 side. The connecting wall 4341f extends approximately parallel to the second wall 4341b and connects the ends of the first wall 4341a and the fifth wall 4341e on the outside X1 side.

[0170] The second wall portion 4341b of the frame covering body 4341 extends further toward the first shoji screen 3 than the abutment surface 431a, and when the first shoji screen 3 and the second shoji screen 4 are abutted against each other, it covers and conceals the entire visible surface 33b on the indoor side X2 of the door-end side vertical stile 33B of the first shoji screen 3. In other words, the second wall portion 4341b covers and conceals the portion of the door-end side spacer 351 of the face material 35 of the first shoji screen 3 and the resin cover 335 that constitutes the visible surface 33b on the indoor side X2 of the door-end side vertical stile 33B of the first shoji screen 3 from the indoor side X2. As a result, the frame covering body 4341 has a shape that is displaced toward the first shoji screen 3 more than the frame body portion 431.

[0171] The resin cover 4342 covers the outer surfaces of the first wall portion 4341a, the second wall portion 4341b, and the third wall portion 4341c of the frame covering portion main body 4341. Specifically, the resin cover 4342 has a first wall portion 4342a covering the first wall portion 4341a of the frame covering portion main body 4341, a second wall portion 4342b covering the second wall portion 4341b of the frame covering portion main body 4341, and a third wall portion 4342c covering the third wall portion 4341c of the frame covering portion main body 4341. The end portion on the outside side X1 of the first wall portion 4341a abuts against a gasket Ga arranged on the indoor side X2 surface of the face material 45, and supports the door edge side of the face material 45 from the indoor side X2. The second wall portion 4342b forms the visible surface 43b on the indoor side X2 of the door-end vertical frame 43B. Furthermore, the resin cover 4342 has a fourth wall portion 4342d between the second wall portion 4342b and the second wall portion 4341b of the frame covering portion main body 4341. The fourth wall portion 4342d extends across the first wall portion 4341a and the third wall portion 4341c, approximately parallel to the second wall portion 4342b and the second wall portion 4341b of the frame covering portion main body 4341. As a result, the resin cover 4342 has a hollow portion 4342e on the indoor side X2 of the second wall portion 4341b of the frame covering portion main body 4341.

[0172] A plurality of protrusions 4342f extending along the length of the resin cover 4342 (perpendicular to the paper surface of FIG. 18) are formed on the inner surface of the resin cover 4342. This forms a gap 4342g between the inner surface of the resin cover 4342 and the outer surface of the frame covering body 4341. The resin cover 4342 has a locking claw 4342h that protrudes from near the end of the first wall portion 4342a on the outside side X1 toward the first shoji screen 3. The resin cover 4342 is attached to the outer surface of the frame covering body 4341 by engaging the locking claw portion 4342h with a locking recess 4341h formed at the corner where the first wall portion 4341a and the connecting wall portion 4341f of the frame covering body 4341 intersect, and by engaging the locking claw portion 4342i protruding inward from near the outside-side X1 end of the third wall portion 4342c with a locking recess 4341i formed at the corner where the third wall portion 4341c and the fourth wall portion 4341d of the frame covering body 4341 intersect.

[0173] As shown in Figure 18, the width of the second wall portion 4342b of the resin cover 4342 that constitutes the visible surface 43b on the indoor side X2 of the leading edge vertical stile 43B is equal to the width of the visible surface 33a of the leading edge vertical stile 33B of the first shoji screen 3 (the width of the second wall portion 330b of the stile covering portion 334). When the fitting 1B is observed from the indoor side X2, the butt joint 10 appears to have a narrow width that is essentially the same as the width of the visible surface 43a of the leading edge vertical stile 43B of the second shoji screen 4 (the width of the second wall portion 4302b of the resin cover 4302 of the stile covering portion 430), resulting in excellent design. Furthermore, the leading edge vertical stile 43B of the second shoji screen 4 has excellent thermal insulation properties due to the resin cover 4342.

[0174] A large space 43S is formed between the fourth wall portion 4341d of the frame covering body 4341 of the leading edge vertical frame 43B of the second shoji screen 4 and the resin cover 335 of the leading edge vertical frame 33B of the first shoji screen 3. This space 43S is provided in a location where the frame covering portion 434 of the leading edge vertical frame 43B of the second shoji screen 4 faces the visible surface 33b on the room side X2 of the leading edge vertical frame 33B of the first shoji screen 3. This space 43S is large enough to allow a finger to be inserted when grasping the frame covering portion 434 of the leading edge vertical frame 43B to open or close the second shoji screen 4.

[0175] A buffer member 437 made of an elastic material such as rubber is provided in the space 43S. The buffer member 437 is attached to the exterior X1 surface of the fourth wall portion 4341d of the frame covering portion main body 4341 so as to protrude toward the interior X2 facing surface 33b of the leading edge vertical frame 33B of the first shoji screen 3. The buffer member 437 has a side surface portion 437a. The side surface portion 437a is positioned approximately flush with the leading edge surface of the frame covering portion 434 on the first shoji screen 3 side (the third wall portion 4342c of the resin cover 4342). As a result, the buffer member 437 is positioned in the space 43S so as to be exposed to the leading edge surface of the frame covering portion 434 (the first shoji screen 3 side). The side surface 437a is disposed substantially flush with the third wall 4342c of the resin cover 4342, so that the side surface 437a closes the space 43S when the first and second shoji screens 3 and 4 are closed, as shown in Fig. 18. Therefore, the design of the indoor side X2 of the butt joint 10 is not impaired.

[0176] The buffer member 437 has an integral protrusion 437b that contacts the interior X2 facing surface 33b (resin cover 335) of the leading vertical stile 33B of the first shoji screen 3 when the first and second shoji screens 3 and 4 are closed. This allows the buffer member 437 to function as an airtight seal between the interior X2 facing surface 33b of the leading vertical stile 33 of the first shoji screen 3. Furthermore, the buffer member 437 has a hollow portion 437c. Therefore, the buffer member 437 has excellent shape retention due to the air within the hollow portion 437c. When external force is applied, the hollow portion 437c (air) is compressed, allowing the buffer member 437 to have moderate elasticity and be easily deformed. Furthermore, the hollow portion 437c also improves the thermal insulation of the buffer member 437.

[0177] As shown in Figure 19, when the operator grasps the stile covering portion 434 of the leading edge vertical stile 43B with his / her hand to open or close the second shoji screen 4, his / her fingertips come into contact with the side surface 437a of the buffer member 437. At this time, the operator can easily sense that his / her fingertips are resting on the side surface 437a of the buffer member 437 (i.e., that his / her finger is not in a position where it could get pinched). Therefore, when the operator closes the first shoji screen 3 and the second shoji screen 4 while grasping the stile covering portion 434 of the leading edge vertical stile 43B, it is possible to prevent his / her finger from getting pinched between the leading edge vertical stile 43B of the second shoji screen 4 and the leading edge vertical stile 33B of the first shoji screen 3. Even if the operator's fingers come too close to the visible surface 33b on the interior side X2 of the door-end vertical frame 33B of the first shoji screen 3, the cushioning member 437 easily elastically deforms, so there is no risk of injuring the fingers.

[0178] The buffer member 437 may be attached to the visible surface 33b on the indoor side X2 of the leading edge vertical frame 33B of the first shoji screen 3. When the buffer member 437 is attached to the leading edge vertical frame 43B of the second shoji screen 4, when the first shoji screen 3 or the second shoji screen 4 is opened, the buffer member 437 is not exposed to the indoor side X2 and cannot be directly seen from the indoor side X2, so the design of the fitting 1B is not impaired.

[0179] As explained above, the fitting 1B of this embodiment has the first shoji screen 3 and the second shoji screen 4 that move on the same rail, and is configured so that the door-end side vertical frames 33B, 43B of the first shoji screen 3 and the second shoji screen 4 abut against each other to be closed. The door-end side vertical frame 43B of the second shoji screen 4 protrudes toward the room side X2 in the front direction, and when the first shoji screen 3 and the second shoji screen 4 are closed, The first shoji screen 3 has a frame covering portion 434 arranged to cover the visible surface 33b on the indoor side X2 of the door-leading vertical frame 33B, and a buffer member 437 is arranged at the location where the frame covering portion 434 of the door-leading vertical frame 43B of the second shoji screen 4 faces the visible surface 33b on the indoor side X2 of the door-leading vertical frame 33B of the first shoji screen 3, so as to be exposed on the visible surface on the door-leading side of the door-leading vertical frame 43B of the second shoji screen 4.

[0180] With this, the operator of the second shoji screen 4 can easily recognize that their fingers are not in a position to be pinched because their fingertips are in contact with the buffer member 437. Therefore, even if the leading edge vertical stile 43B of one second shoji screen 4 has a stile shape that covers and swallows the outside of the leading edge vertical stile 33B of the other first shoji screen 3, their fingers will not be pinched when opening or closing the screen.

[0181] In the fitting 1B of this embodiment, the buffer member 437 is attached to the vertical frame 43 on the door end side of the second shoji screen 4.

[0182] According to this, when the first shoji screen 3 or the second shoji screen 4 is opened, the buffer member 437 is not exposed to the inside X2 of the room. Since the buffer member 437 is not directly visible from the inside X2 of the room, the design of the fitting 1B is not impaired.

[0183] In the fitting 1B of this embodiment, the buffer member 437 has a hollow portion 437c.

[0184] This improves operability and prevents injury to the operator's fingers even if the operator's fingers come too close to the visible surface 33b of the door-end vertical frame 33B on the indoor side X2 of the first shoji screen 3, because the buffer member 437 easily deforms elastically. Moreover, the thermal insulation of the buffer member 437 is also improved.

[0185] The building fixture of the present disclosure includes the following aspects.

[0186] <Mode B1> A fitting having a first shoji screen and a second shoji screen that move on the same rail, and configured so that the butt frames of the first shoji screen and the second shoji screen are butted together when closed, wherein the butt frame of the first shoji screen protrudes toward the room in the front direction and has a frame covering part that is arranged to cover the visible surface on the room side of the butt frame of the second shoji screen when the first shoji screen and the second shoji screen are closed, and a buffer member is arranged at the location where the frame covering part of the butt frame of the first shoji screen and the visible surface on the room side of the butt frame of the second shoji screen face each other so as to be exposed at the door tip surface of the butt frame of the first shoji screen.

[0187] <Aspect B2> The fitting according to Aspect B1, wherein the buffer member is attached to the butt frame side of the first shoji screen.

[0188] <Aspect B3> The fitting according to Aspect B1 or B2, wherein the buffer member has a hollow portion.

[0189] However, when the front-end stile of one shoji screen covers the outside of the front-end stile of the other shoji screen at the butt joint, the other shoji screen, whose front-end stile is located on the inside, is obstructed by the front-end stile covering the outside, making it impossible to directly open or close the inner front-end stile by hand. Therefore, it is difficult to open or close only the other shoji screen whose front-end stile is located on the inside. Therefore, below, we will describe a fitting 1C that can solve the problem of providing a fitting in which the front-end stiles of two shoji screens that move on the same rail are butted together to close, and one front-end stile is arranged to cover the outside of the other, allowing both front-end stiles of the shoji screens to be opened or closed by hand, thereby improving operability.

[0190] Figures 20 to 24 show a fitting 1C according to yet another embodiment. The fitting 1C is a modified version of the fitting 1B described above. Figure 20 is a front view of the fitting 1C as seen from the inside X2 of the room. The fitting 1C is similar to the fittings 1, 1A, and 1B in that it is provided with a first shoji screen 3 and a second shoji screen 4 located on the inside X2 of the room, and a third shoji screen 5 and a fourth shoji screen 6 located on the outside X1 of the room, each of which can slide left and right inside the frame 2. Since parts with the same reference numerals as the fittings 1, 1A, and 1B described above indicate components with the same functions, detailed descriptions of these parts will be cited from the descriptions of the fittings 1, 1A, and 1B and may be omitted below.

[0191] Like the fittings 1, 1A, and 1B, the fitting 1C is closed by abutting the third shoji 5 and fourth shoji 6 at both ends against the vertical frames 23 and 24, respectively, and by abutting the first shoji 3 and second shoji 4 located on the room's inside side X2 at the center of the fitting 1C. In the closed state, a butt joint 10 between the first shoji 3 and second shoji 4 is formed in the center of the fitting 1C. The butt joint 10 is formed by the leading vertical frames 33C and 43C of the first shoji 3 and second shoji 4 that are abutted at the center.

[0192] 21A to 21C, the opening and closing operations of the first shoji screen 3 and the second shoji screen 4 in the fitting 1B will be described. 21A to 21C are schematic diagrams each illustrating the opening and closing operations of the fitting 1C, showing the first shoji screen 3, the second shoji screen 4, the third shoji screen 5, and the fourth shoji screen 6 in a plan view. 21A to 21C omit the illustration of the indoor rails and the indoor rails along which these shoji screens 3, 4, 5, and 6 slide.

[0193] First, when opening or closing the first shoji screen 3 from the inside X2, as shown in Fig. 21A, the trailing edge stile 34 of the first shoji screen 3, which protrudes toward the inside X2, is grasped by hand and slid in the direction of the white arrow. When opening or closing the second shoji screen 4 from the inside X2, as shown in Fig. 21B, the leading edge stile 43C or the trailing edge stile 44 of the second shoji screen 4, which protrudes toward the inside X2, is grasped by hand and slid in the direction of the white arrow. Furthermore, when opening or closing the first shoji screen 3 from the outside X1, as shown in Fig. 21C, the leading edge stile 33C of the first shoji screen 3, which protrudes toward the outside X1, is grasped by hand and slid in the direction of the white arrow. The third shoji screen 5 and the fourth shoji screen 6 can be opened or closed from either the outside X1 or the inside X2 using the handle recesses 531, 631.

[0194] On the other hand, the leading edge stile 43C of the second shoji screen 4 is covered from the outside X1 by the leading edge stile 33C of the first shoji screen 3, and does not have any protruding portion toward the outside X1. Therefore, even if you try to open or close only the second shoji screen 4 from the outside X1, you cannot grab the leading edge stile 43C by hand and slide it as described above. However, the leading edge stiles 33C, 43C of the first shoji screen 3 and the second shoji screen 4 of the fitting 1C are configured in the manner described below, so that the leading edge stile 43C of the second shoji screen 4 can be opened or closed directly by hand from the outside X1.

[0195] The specific configuration of the leading edge vertical frames 33C, 43C of the first shoji screen 3 and second shoji screen 4 in the fitting 1C will be described using Figures 22 to 24. Figures 22 to 24 are enlarged cross-sectional views showing the butt joint 10 between the first shoji screen 3 and the second shoji screen 4 in the fitting 1C. The first shoji screen 3 and the second shoji screen 4 are arranged to be slidable on the same indoor rails 211, 221, but only the indoor rail 221 of the lower horizontal frame 22 is shown in Figures 22 to 24.

[0196] The fitting 1C differs in the configuration of the frame covering portion 334 of the leading edge vertical frame 33C of the first shoji screen 3. In fitting 1C, the third wall portion 334c of the frame covering portion 334 of the leading edge vertical frame 33C of the first shoji screen 3 only extends slightly toward the room's interior side X2. A fifth wall portion 334f extends from a position closer to the first wall portion 334a than the third wall portion 334c of the second wall portion 334b ​​toward the room's interior side X2, approximately parallel to the first wall portion 334a. The fourth wall portion 334d connects the outside X1 end of the frame main body portion 331 to the inside X2 end of the fifth wall portion 334f. Therefore, as shown in Figure 22, when the first shoji screen 3 and the second shoji screen 4 are closed, a large space is formed between the second wall portion 334b ​​and the visible surface 43a on the exterior side X1 of the leading edge vertical stile 43C of the second shoji screen 4. This space gives the visible surface of the stile covering portion 334 on the second shoji screen 4 side a recessed shape, thereby forming a recess 334g large enough for a finger to be inserted. The recess 330g is formed along the length direction of the leading edge vertical stile 33C (perpendicular to the paper surface of Figure 22).

[0197] When the fitting 1C is viewed horizontally (left and right in FIG. 22), the fifth wall portion 334f is positioned at approximately the same position as the abutting surface 431a of the leading edge vertical stile 43C of the second shoji screen 4. A part of the exterior-side X1 facing surface 43a of the leading edge vertical stile 43C of the second shoji screen 4 faces into a recess 334g having this fifth wall portion 334f as its bottom.

[0198] A finger hook 438 that rises approximately vertically toward the exterior side X1 is integrally formed on the end (right side in Figure 22) of the trailing edge of the door-end vertical stile 43 of the second shoji screen 4. This finger hook 438 is formed along the length of the door-end vertical stile 43C. When viewing the fitting 1C horizontally (left and right in Figure 22), the finger hook 438 is located in approximately the same position as the third wall portion 334c of the stile covering portion 334 of the door-end vertical stile 33C of the first shoji screen 3. The finger hook 438 rises slightly toward the exterior side X1, but protrudes high enough to allow a finger to be hooked. When the first shoji screen 3 and the second shoji screen 4 are closed, the recess 334g of the frame covering portion 334 on the vertical frame 33C on the door end side of the first shoji screen 3 opens between the finger hook portion 438 and the third wall portion 334c of the frame covering portion 334.

[0199] In this fitting 1C, when opening or closing the second shoji screen 4 from the outside X1, as shown in Figure 23, the operator inserts a finger into the recess 334g formed in the stile covering portion 334 of the leading edge vertical frame 33 of the first shoji screen 3, hooks the tip of the finger into the finger hook 438 formed in the leading edge vertical frame 43C of the second shoji screen 4, and slides the second shoji screen 4. This allows the second shoji screen 4 to be easily opened or closed from the outside X1. The finger hook 438 is located on approximately the same plane as the third wall portion 334c of the stile covering portion 334 of the first shoji screen 3, making it inconspicuous. Therefore, there is no risk of the design of the butt joint 10 being impaired when viewing the fitting 1C from the outside X1.

[0200] 24 shows another embodiment of the leading-side vertical stile 33C of the first shoji screen 3. The fifth wall 334f of the stile covering portion 334 of this leading-side vertical stile 33C is formed to connect the indoor-side X2 end of the third wall 334c and the second shoji screen 4 side end of the fourth wall 334d. Specifically, the outdoor-side X1 end of the fifth wall 334f has an outdoor-side end 334f1 that bends toward the second shoji screen 4 side and connects to the indoor-side X2 end of the third wall 330c. The indoor-side X2 end of the fifth wall 334f has an indoor-side end 334f2 that forms an inclined surface that slopes toward the first wall 330a as it approaches the fourth wall 334d.

[0201] The width of the exterior end 334f1 in the view direction is smaller than the width of the second wall 334b ​​in the view direction. As shown in Figure 24, when the first shoji screen 3 and the second shoji screen 4 are closed, the position of the end of the exterior end 334f1 on the first wall 334a side is located between the abutting surface 431a and the finger hook 438 of the leading edge vertical stile 43C of the second shoji screen 4. The interior end 334f2 of the fifth wall 334f is inclined toward the first wall 334a from near the center in the protruding direction of the stile covering portion 334 (the up-down direction in Figure 24) toward the interior side X2. The position of the connection between the indoor end portion 334f2 and the fourth wall portion 334d is located at approximately the same position as the abutment surface 431a of the door-end vertical frame 43C of the second shoji screen 4 when viewed horizontally (left and right in Figure 24) of the building fixture 1C.

[0202] The depth of the recess 334g of the stile covering portion 334 shown in Figure 24 is shallower than the depth of the recess 334g of the stile covering portion 334 shown in Figure 22. Therefore, when the leading edge vertical stile 33C of the first shoji screen 3 is observed from the outside X1, the recess 334g does not appear as a large depression, further improving the design of the fitting 1C. Furthermore, the recess 334g of the stile covering portion 334 shown in Figure 24 becomes deeper toward the inside X2 because the indoor end 334f2 of the fifth wall portion 334f forms a sloped surface. As a result, when a finger is inserted into the recess 334g to hook onto the finger hook 438, it is guided along the slope of the indoor end 334f2 of the fifth wall portion 334f, allowing the finger inserted into the recess 334g to smoothly hook onto the finger hook 438 of the second shoji screen 4.

[0203] In the above embodiment, the recess 334g and the finger hook 438 are arranged on the exterior side X1 of the fitting 1C, but they may also be arranged on the interior side X2 of the fitting 1C. Although not shown, the recess 334g and the finger hook 438 may be formed on both the leading edge vertical frame 33C of the first shoji screen 3 and the leading edge vertical frame 43C of the second shoji screen 4.

[0204] As explained above, the fitting 1C of this embodiment has the first shoji screen 3 and the second shoji screen 4 that move on the same rail, and is configured so that the door-end side vertical frames 33C, 43C of the first shoji screen 3 and the second shoji screen 4 abut against each other when closed. The door-end side vertical frame 33C of the first shoji screen 3 protrudes to the outside X1 on one side of the room in the projection direction, and when the first shoji screen 3 and the second shoji screen 4 are closed, the door-end side vertical frame 43C of the second shoji screen 4 abuts against each other when closed. The frame covering portion 334 has a recess 334g on the front surface facing the second shoji screen 4 into which a finger can be inserted, and when the first shoji screen 3 and the second shoji screen 4 are closed, the front surface 43a of the leading edge vertical frame 43C of the second shoji screen 4 faces into the recess 334g, and the leading edge vertical frame 43C of the second shoji screen 4 has a finger hook portion 438 that rises from the front surface 43a facing into the recess 334g.

[0205] This allows the leading edge vertical frame 33C, 43C of either the first shoji screen 3 or the second shoji screen 4 to be opened and closed manually from one side in the forward direction, improving operability.

[0206] In the fitting 1C of this embodiment, the recess 334g has an inclined surface that becomes deeper as it approaches the visible surface 43a of the door-end vertical frame 43C of the second shoji screen 4.

[0207] With this, when inserting a finger into the recess 334g, the finger is guided along the inclined surface, so that the finger inserted into the recess 334g can be smoothly hooked onto the finger hook portion 438 of the second shoji screen 4.

[0208] In the building fixture 1C of this embodiment, the frame covering portion 334 and the finger hook portion 438 are arranged on the outside side X1.

[0209] This allows both the first shoji screen 3 and the second shoji screen 4 to be opened and closed by fingers from the outside X1 of the room.

[0210] The building fixture of the present disclosure includes the following aspects.

[0211] <Mode C1> A fitting having a first shoji screen and a second shoji screen that move on the same rail, and configured so that the butt frames of the first shoji screen and the second shoji screen are butted together when closed, wherein the butt frame of the first shoji screen protrudes in one direction of the front view and has a frame covering part that is arranged to cover the visible surface of the butt frame of the second shoji screen when the first shoji screen and the second shoji screen are closed, wherein the frame covering part has a recess in the front view surface facing the second shoji screen into which a finger can be inserted, and wherein the visible surface of the butt frame of the second shoji screen faces into the recess when the first shoji screen and the second shoji screen are closed, and wherein the butt frame of the second shoji screen has a finger hook part that rises from the visible surface that faces into the recess.

[0212] <Aspect C2> The fitting according to Aspect C1, wherein the recess has an inclined surface that becomes deeper as it approaches the visible surface of the butt frame of the second shoji screen.

[0213] <Aspect C3> The fitting according to Aspect C1 or C2, wherein the frame covering portion and the finger hook portion are arranged on the exterior side of the room.

[0214] However, when the vertical stiles on the door edge of one shoji screen and the vertical stiles on the door edge of the other shoji screen are structured to fit together over almost the entire vertical area, it can be difficult to butt them together if one or both of the shoji screens are at an angle due to the fitting method. On the other hand, if the vertical stiles on the door edge are not fitted together, there is a risk that wind pressure resistance and airtightness will be reduced. Therefore, below, we will explain fitting 1D, which can solve the problem of providing fittings that are not easily affected by fitting and can achieve high wind pressure resistance and airtightness.

[0215] Figures 25 to 41 show a fitting 1D of yet another embodiment. Figure 25 is a front view of the fitting 1D as seen from the indoor side X2. The fitting 1D is similar to the fittings 1, 1A, 1B, and 1C in that it has a first shoji screen 3 and a second shoji screen 4 arranged on the indoor side X2, and a third shoji screen 5 and a fourth shoji screen 6 arranged on the outdoor side X1, each of which can slide left and right inside the frame 2. Since parts with the same reference numerals as those in the fittings 1, 1A, 1B, and 1C above indicate components with the same functions, detailed descriptions of these parts will be incorporated in the descriptions of the fittings 1, 1A, 1B, and 1C and may be omitted below.

[0216] The leading edge stile 33D of the first shoji screen 3, like the leading edge stile 33C of the first shoji screen 3 of the fitting 1C shown in Figures 22 and 24, has a recess 334g on the visible surface on the second shoji screen 4 side into which a hand can be inserted, and has a stile covering portion 334 that protrudes toward the outside X1. As shown in Figures 28 and 29, the leading edge stile 43D of the second shoji screen 4 has a stile main body portion 431 and a stile covering portion 434 that is connected to the stile main body portion 431 via a bridge portion 435 and has a shape that protrudes toward the inside X2. A guide block 9 is arranged on the abutting surface 431a of the stile main body portion 431.

[0217] The guide block 9 will now be described in further detail. Figure 29 is an enlarged perspective view showing the leading edge vertical stile 43 of the second shoji screen 4 of the fitting 1D. As shown in Figure 29, the guide block 9 is disposed inside a recess 431d formed by the abutment surface 431a, the extension portion 431b, and the standing wall portion 431c in the stile body portion 431 of the leading edge vertical stile 43.

[0218] Fig. 30 is a perspective view showing the front side (side facing the first shoji screen 3) of the guide block 9. Fig. 31 is a perspective view showing the back side (side facing the abutment surface 431a) of the guide block 9. As shown in Figs. 30 and 31 , the guide block 9 includes a guide groove 91, two holding pieces 92, two protrusions 93, and a convex portion 94.

[0219] The guide groove 91 is formed as a groove into which the extension piece 3314 of the door-end vertical frame 33D of the first shoji screen 3 is inserted. The inner surface of the guide groove 91 is formed in a tapered shape so that the tip of the extension piece 3314 can be smoothly guided toward the back side.

[0220] The two holding pieces 92 are formed to be elastically deformable. A biasing force acts on the two holding pieces 92 so that they brace against the inside of the recess 431d, thereby preventing the guide block 9 from coming off the recess 431d.

[0221] The two protrusions 93 are formed on opposite sides of the two holding pieces 92. In this embodiment, a recess-side extension piece 431e extending toward the outdoor side X1 in the forward direction is formed on the indoor side X2 in the forward direction of the recess 431d. The two protrusions 93 are caught on the recess-side extension piece 431e from the inside, thereby preventing the guide block 9 from separating from the recess 431d.

[0222] The protrusion 94 is formed between the two protrusions 93. In this embodiment, a fitting recess 431f that determines the position of the guide block 9 is formed in the recess-side extension piece 431e. The protrusion 94 fits into this fitting recess 431f, thereby determining the vertical position of the guide block 9 in the recess 431d.

[0223] The guide block 9 is firmly fixed to the leading edge vertical frame 43D of the second shoji screen 4 without moving up, down, left or right due to the multiple retaining pieces 92, multiple protrusions 93 and convex portions 94.

[0224] Here, the function of the guide block 9 in the butted state will be described with reference to Figure 28. In the butted state, the extension piece 3314 of the leading edge vertical stile 33D of the first shoji screen 3 is inserted into the guide groove 91. In this state, even if either or both of the first shoji screen 3 and the second shoji screen 4 move away from each other in the forward direction, the guide groove 91 restricts the movement of the extension piece 3314 in the forward direction.

[0225] Gaps are more likely to occur in the vertical center due to the influence of wind pressure, etc., compared to the upper and lower ends of the leading edge stiles 33D, 43D at the butt joint 10, where separation is prevented by the presence of the indoor rails 211, 221. In this regard, the guide block 9 of this embodiment is fixed to the recess 431d at a position away from the upper and lower ends of the leading edge stile 43D of the second shoji screen 4, so that gaps between the leading edge stiles 33D, 43D in the vertical center can be effectively prevented.

[0226] The building fixture 1D of this embodiment further includes a structure that prevents the door-end vertical frames 33D, 43D from swaying up and down.

[0227] First, we will explain the structure for preventing the upper part of the leading edge vertical frame 33D of the first shoji screen 3 and the leading edge vertical frame 43D of the second shoji screen 4 from shaking. Figure 32 is a plan view showing the structure of the butt joint 10 of the fitting 1D. In Figure 32, the leading edge vertical frames 33D, 43D are indicated by two-dot chain lines.

[0228] As shown in Figure 32, an upper end cap 110 is fitted to the upper end of the leading edge vertical stile 33D, and an upper end cap 120 is also fitted to the upper end of the leading edge vertical stile 43D. The upper end caps 110 and 120 have corresponding shapes and are configured to be able to fit together in a butted state.

[0229] The upper end cap 110 of the leading edge vertical stile 33D will now be described. Figure 33 is a perspective view showing the upper end cap 110 of the leading edge vertical stile 33D of the first shoji screen 3 located on one side in the left-right direction from above, and Figure 34 is a perspective view showing the upper end cap 110 from below.

[0230] As shown in Figures 32 to 34, the upper end cap 110 has an insertion portion 111, an indoor rail guide groove 112, a pair of mating protrusions 113, an outdoor rail guide groove 114, a through hole 115, a drainage hole 116, an attachment hole 117, and abutment portions 118a, 118b.

[0231] The insertion portion 111 is a portion that is fitted into the inside of the door-end vertical frame 33D. The indoor rail guide groove 112 is a portion that covers the guide groove 411 that guides the indoor rail 211, and is formed in a groove shape with an open upper end.

[0232] A pair of mating protrusions 113 are formed on each side of the indoor rail guide groove 112. The surface of the mating protrusion 113 located on the outdoor side X1 in the projection direction is inclined so as to approach the indoor side X2 as it progresses from the base end to the tip end. The surface of the mating protrusion 113 located on the indoor side X2 in the projection direction is inclined so as to approach the outdoor side X1 as it progresses from the base end to the tip end. The pair of mating protrusions 113 are tapered overall, tapering from the base end to the tip end.

[0233] The exterior rail guide groove 114 is a portion that covers a guide groove (not shown) that guides the exterior rail 212, and is formed as a groove with an open upper end. The through-hole 115 functions as a filler, and the drain hole 116 functions as an outlet that drains water that has entered through the through-hole 115 to the outside. The mounting hole 117 is for fixing the upper end cap 110 to the door-end vertical stile 33D with a fastening member such as a screw.

[0234] The abutment portion 118a protrudes in the left-right direction toward the fourth shoji screen 6. The closest distance between the first shoji screen 3 and the fourth shoji screen 6 can be adjusted by adjusting the left-right length of the abutment portion 118a. The abutment portion 118b protrudes in the left-right direction toward the third shoji screen 5. The closest distance between the first shoji screen 3 and the third shoji screen 5 can be adjusted by adjusting the left-right length of the abutment portion 118b. Setting the closest distance between the first shoji screen 3 and the third shoji screen 5 and the fourth shoji screen 6 with a margin of error can prevent the user's fingers from getting caught.

[0235] The following describes the upper end cap 120 on the leading edge vertical stile 43D side of the second shoji screen 4. Figure 35 is a perspective view showing the upper end cap 120 of the leading edge vertical stile 43D of the second shoji screen 4 located on the other side in the left-right direction from above, and Figure 36 is a perspective view showing the upper end cap 120 from below.

[0236] As shown in Figures 35 and 36, the upper end cap 120 has an insertion portion 121, an indoor rail guide groove 122, a fitting recess 123, a lid portion 124, an adjustment groove 125, and a mounting hole 126.

[0237] The insertion portion 121 is fitted into the inside of the door-end vertical stile 43D. The indoor rail guide groove 122 is a portion that covers a guide groove (not shown) that guides the indoor rail 211, and is formed in a groove shape with an open upper end. The indoor rail guide groove 122 corresponds to the indoor rail guide groove 112.

[0238] The fitting recesses 123 are portions that fit into a pair of fitting protrusions 113, and are formed on both sides of the indoor rail guide groove 122. The lid portion 124 is a portion that covers the upper end surface of the indoor side X2 of the door-end vertical stile 43D.

[0239] The adjustment groove 125 is a vertical groove formed in the lower end of the upper end cap 120. The adjustment groove 125 is a groove that allows for vertical displacement of the extension piece 3314 of the leading edge vertical stile 33D. The mounting hole 126 is for fixing the upper end cap 120 to the leading edge vertical stile 43D with a fastening member such as a screw.

[0240] In this embodiment, when the leading-side vertical stile 33D and the leading-side vertical stile 43D are butted together, the positions of the leading-side vertical stile 33D and the leading-side vertical stile 43D are guided by the fitting structure of the upper end cap 110 of the leading-side vertical stile 33D and the upper end cap 120 of the leading-side vertical stile 43D. Therefore, the leading-side vertical stile 33D and the leading-side vertical stile 43D fit into the appropriate position without the upper part of the butt joint 10 shaking.

[0241] Next, the function of preventing the lower part of the leading edge vertical stile 33D and the leading edge vertical stile 43D from shaking will be explained. Figure 37 is a bottom view showing the configuration of the butt joint 10 of the fitting 1D. In Figure 37, the leading edge vertical stile 33D and the leading edge vertical stile 43D are also shown by two-dot chain lines. Because Figure 37 is a bottom view, the paper orientation is upside down compared to Figure 32.

[0242] As shown in Figure 37, a lower end cap 130 is fitted to the lower end of the leading-side vertical stile 33D, and a lower end cap 140 is also fitted to the lower end of the leading-side vertical stile 43D. The lower end caps 130 and 140 have corresponding shapes and are configured to be able to fit together in a butted state.

[0243] The lower end cap 130 of the leading edge vertical stile 33D will now be described. Figure 38 is a perspective view showing the lower end cap 130 of the leading edge vertical stile 33D of the first shoji screen 3 located on one side in the left-right direction from the front side, and Figure 39 is a perspective view showing the lower end cap 130 from the back side.

[0244] As shown in Figures 38 and 39, the lower end cap 130 has an insertion portion 131, an indoor rail guide groove 132, a mating protrusion 133, an outdoor rail guide groove 134, a through hole 135, an attachment hole 136, a door roller adjustment hole 137, and abutment portions 138a, 138b.

[0245] The insertion portion 131 is a portion that is fitted into the inside of the door-end vertical frame 33D. The indoor rail guide groove 132 is a portion that covers a groove that guides the indoor rail 221, and is formed in a groove shape with an open upper end.

[0246] The mating protrusion 133 protrudes in the left-right direction. The mating protrusion 133 is tapered from the base end toward the tip end. The exterior rail guide groove 134 covers the groove that guides the exterior rail 222 and is formed as a groove with an open lower end. The multiple through holes 135 function as recesses. The mounting holes 136 are for fixing the lower end cap 130 to the door-end vertical stile 33D with fastening members such as screws.

[0247] The roller adjustment hole 137 is a hole for adjusting the height of the roller 3b (see FIG. 26) of the first shoji screen 3. By inserting a tool through the roller adjustment hole 137, the height of the roller 3b can be adjusted, and the height of the first shoji screen 3 can be changed.

[0248] The abutment portion 138a protrudes in the left-right direction toward the fourth shoji screen 6. The closest distance between the first shoji screen 3 and the fourth shoji screen 6 can be adjusted by adjusting the left-right length of the abutment portion 138a. The abutment portion 138b protrudes in the left-right direction toward the third shoji screen 5. The closest distance between the first shoji screen 3 and the third shoji screen 5 can be adjusted by adjusting the left-right length of the abutment portion 138b. Setting the closest distance between the first shoji screen 3 and the third shoji screen 5 and the fourth shoji screen 6 with a margin of error can prevent the user's fingers from getting caught.

[0249] The lower end cap 140 of the leading edge vertical stile 43D of the second shoji screen 4 located on the other side in the left-right direction will be described. Figure 40 is a perspective view showing the lower end cap 140 of the leading edge vertical stile 43D of the second shoji screen 4 from the front side, and Figure 41 is a perspective view showing the lower end cap 140 from the back side.

[0250] As shown in Figures 40 and 40, the lower end cap 140 has an insertion portion 141, an indoor rail guide groove 142, a fitting recess 143, a lid portion 144, an adjustment groove 145, an attachment hole 146, and a door roller adjustment hole 147.

[0251] The insertion portion 141 is fitted into the inside of the door-end vertical stile 43D. The indoor rail guide groove 142 is a portion that covers the groove that guides the indoor rail 211, and is formed in a groove shape with an open lower end. The indoor rail guide groove 142 corresponds to the indoor rail guide groove 132.

[0252] The fitting recess 143 is a portion that fits into the fitting protrusion 133. The lid portion 144 is a portion that covers the lower end surface of the indoor side X2 of the door-end vertical frame 43D.

[0253] The adjustment groove 145 is a vertical groove formed in the lower end of the lower end cap 140. The adjustment groove 145 is formed inside the fitting recess 143. The adjustment groove 145 is a groove that allows for vertical displacement of the extension piece 3314 of the door-end vertical stile 33D.

[0254] The mounting hole 146 is for fixing the lower end cap 140 to the door-front vertical frame 43D with a fastening member such as a screw. The door roller adjustment hole 147 is a hole for adjusting the height of the door roller (not shown) of the second shoji screen 4. By inserting a tool through the door roller adjustment hole 147, the height of the door roller can be adjusted to change the height of the second shoji screen 4.

[0255] Next, we will explain the airtight line AL formed in the vertical direction at the center of the butt joint 10 in the projection direction. Figure 42 is a side view showing the indoor side X2 of the door-end vertical frame 33D of the first shoji screen 3 located on one side in the left-right direction. In Figure 42, the airtight line AL formed in the center of the butt joint 10 in the projection direction is indicated by a hollow arrow.

[0256] As shown in Figure 42, the airtight line AL is formed at its center by the extension piece 3314 of the first shoji screen 3, with which the airtight material 436 of the second shoji screen 4 comes into contact. The upper part of the airtight line AL is formed by the upper end cap 110 of the first shoji screen 3, which fits into the upper end cap 120 of the second shoji screen 4. The upper part of the airtight line AL is offset toward the outside X1 in the projection direction from the extension piece 3314 so as to avoid the inside rail guide groove 112. The lower part of the airtight line AL is formed by the lower end cap 130 of the first shoji screen 3, which fits into the lower end cap 140 of the second shoji screen 4. The lower part of the airtight line AL is also offset toward the outside X1 in the projection direction from the extension piece 3314 so as to avoid the inside rail guide groove 132.

[0257] Next, we will explain the functions of the adjustment groove 125 of the upper end cap 120 and the adjustment groove 145 of the lower end cap 140. Figure 43 is a side view showing the outdoor side X1 portion of the leading vertical stile 43D of the second shoji screen 4 located on the other side in the left-right direction. In Figure 43, the extension piece 3314 of the first shoji screen 3 is shown by a two-dot chain line.

[0258] As shown in FIG. 43, the adjustment groove 125 of the upper end cap 120 and the adjustment groove 145 of the lower end cap 140 both correspond to the projection position of the extension piece 3314 and are aligned vertically.

[0259] When the first shoji screen 3 and the second shoji screen 4 are butted together, the upper end of the extension piece 3314 is configured to partially fit into the adjustment groove 125 of the upper end cap 120. Even in this state, the vertical length of the adjustment groove 125 is set with a margin so that a gap L1 is created between the upper end of the adjustment groove 125 and the upper end of the extension piece 3314. As a result, even if the height of the door roller is adjusted from the state shown in Figure 43 and the extension piece 3314 moves upward, the amount of movement L1 can be tolerated. Similarly, even if the height of the door roller is adjusted and the extension piece 3314 moves downward, the amount of movement L2 can be tolerated by the adjustment groove 145 of the lower end cap 140.

[0260] Next, we will explain what happens when the door-end side vertical stile 33D and the door-end side vertical stile 43D are separated by a distance d1 from the proper butt state as shown in Figure 44. Figure 44 is an enlarged cross-sectional view showing a state in which a gap has occurred in the left-right direction at the butt joint 10 of the fitting 1D of this embodiment. In Figure 44, the door-end side vertical stile 33D and the door-end side vertical stile 43D are indicated by two-dot chain lines.

[0261] The extension piece 3314 on the first shoji screen 3 side is a plate-like member extending in the left-right direction. The tip of the airtight material 436 protruding from the second shoji screen 4 side from the outside side X1 in the projection direction to the inside side X2 in the projection direction comes into contact with the visible surface 3314a on the outside side X1 of the extension piece 3314, thereby forming the center side of the airtight line AL.

[0262] In this embodiment, the length d2 of the extension piece 3314 is given a margin in the left-right direction so that contact between the extension piece 3314 and the airtight material 436 is maintained even if the door-end-side vertical stile 33D and the door-end-side vertical stile 43D are separated by a distance d1 from the appropriate butt state. Even if the door-end-side vertical stile 33D and the door-end-side vertical stile 43D are separated by the distance d1, airtightness is maintained at the center of the airtight line AL. Therefore, even if the positions of the first shoji screen 3 and the second shoji screen 4 become slanted due to fitting adjustment, contact between the extension piece 3314 and the airtight material 436 can be maintained.

[0263] Even above the airtight line AL, even when the leading-edge vertical frame 33D and the leading-edge vertical frame 43D are separated by a distance d1, the upper end caps 110 and 120 overlap alternately in the forward direction, leaving only a small gap. The same is true for the positional relationship between the lower end caps 130 and 140 at the bottom of the airtight line AL. In other words, even when the leading-edge vertical frame 33D and the leading-edge vertical frame 43D are separated by a distance d1 above and below the airtight line AL, a decrease in airtightness can be effectively suppressed.

[0264] As explained above, the fitting 1D according to this embodiment is equipped with the first shoji screen 3 and the second shoji screen 4 that move on the same indoor rails 211, 221, and is configured so that the door-end side vertical frames 33D, 43D of the first shoji screen 3 and the second shoji screen 4 abut against each other to be closed. The door-end side vertical frame 33D of the first shoji screen 3 has an extension piece 3314 that extends from the front surface on the second shoji screen 4 side to the second shoji screen 4 side, and the door-end side vertical frame 43D of the second shoji screen 4 protrudes to one side in the front direction (the indoor side X2), and when the first shoji screen 3 and the second shoji screen 4 are closed, The frame covering portion 434 is arranged to cover one side of the visible surface 33b in the projection direction of the vertical frame 33D on the door edge side of the first shoji screen 3 when the first shoji screen 3 is closed; an airtight material 436 is arranged in a recess 431d formed in the visible surface on the first shoji screen 3 side, extends to one side in the projection direction, and comes into contact with the extension piece 3314 when the first shoji screen 3 and the second shoji screen 4 are closed; and a guide block 9 as a guide member which is arranged in the recess 431d and has a guide groove 91 into which the tip of the extension piece 3314 is inserted when the first shoji screen 3 and the second shoji screen 4 are closed.

[0265] This allows the airtight material 436 of the second shoji screen 4 to contact the extension piece 3314 of the first shoji screen 3 in the projection direction. Even if a misalignment occurs in the left-right direction when the shoji screens 3 and 4 are butted together, or if either the first shoji screen 3 or the second shoji screen 4 is tilted, a sufficient contact gap can be secured to maintain contact between the airtight material 436 and the extension piece 3314. This ensures greater airtightness and watertightness than conventional products, while being less susceptible to fitting adjustments. Furthermore, the guide block 9 can restrict the movement of the first shoji screen 3 and the second shoji screen 4 in the projection direction when they are butted together. This effectively increases the fastening force between the first shoji screen 3 and the second shoji screen 4, improving wind pressure resistance. This means that the fitting 1D is less susceptible to fitting adjustments and has high wind pressure resistance and airtightness.

[0266] In the fitting 1D of this embodiment, the door-end side vertical stile 33D of the first shoji screen 3 has an upper end cap 110 and a lower end cap 130 as first end members arranged at the longitudinal ends, and the door-end side vertical stile 43D of the second shoji screen 4 has an upper end cap 120 and a lower end cap 140 as second end members arranged at the longitudinal ends. The upper end cap 110 and the upper end cap 120 on one longitudinal side (upper side) are configured to fit together when the first shoji screen 3 and the second shoji screen 4 are closed, and the lower end cap 130 and the lower end cap 140 on the other longitudinal side (lower side) are configured to fit together when the first shoji screen 3 and the second shoji screen 4 are closed.

[0267] According to this, the fitting structure of the upper end caps 110 and 120 guides the upper parts of the first and second shoji screens 3 and 4 to the correct position when they are butted together, and also effectively prevents the upper part of the butt joint 10 from shaking out when they are butted together. Similarly, the fitting structure of the lower end caps 130 and 140 guides the lower parts of the first and second shoji screens 3 and 4 to the correct position when they are butted together, and also effectively prevents the lower part of the butt joint 10 from shaking out when they are butted together.

[0268] In the fitting 1D of this embodiment, the upper end cap 110 has an indoor side rail guide groove 112 that holds the indoor side rail 211 and is formed adjacent to or overlapping the extension piece 3314 in the prospective direction, the upper end cap 120 has an indoor side rail guide groove 122 that holds the indoor side rail 211. The lower end cap 130 has an indoor side rail guide groove 132 that holds the indoor side rail 221 and is formed adjacent to or overlapping the extension piece 3314 in the prospective direction, and the lower end cap 140 has an indoor side rail guide groove 142 that holds the indoor side rail 221.

[0269] With this, the extension piece 3314 and the upper end cap 110 and the lower end cap 130 are continuous in the vertical direction, so that the airtightness line AL between the first shoji screen 3 and the second shoji screen 4 can be formed over the entire vertical area. The fitting structure of the upper end cap 110 and the upper end cap 120 can be utilized, so that the airtightness line AL above the extension piece 3314 can be offset in the prospective direction so as to avoid the indoor rail guide groove 122. Similarly, the fitting structure of the lower end cap 130 and the lower end cap 140 can be utilized, so that the airtightness line AL below the extension piece 3314 can be offset in the prospective direction so as to avoid the indoor rail guide groove 142. Therefore, even in a configuration in which the first shoji screen 3 and the second shoji screen 4, which move on the same indoor rails 211, 221, are butted together, the airtightness line AL can be formed uninterrupted over the entire vertical area or almost the entire area.

[0270] In the fitting 1D of this embodiment, the upper end cap 120 corresponds to the position of the extension piece 3314 when the first shoji screen 3 and the second shoji screen 4 are closed, and an adjustment groove 125 is formed that extends toward the end in the longitudinal direction of the leading edge stile 43D. The lower end cap 140 corresponds to the position of the extension piece 3314 when the first shoji screen 3 and the second shoji screen 4 are closed, and an adjustment groove 145 is formed that extends toward the end in the longitudinal direction of the leading edge stile 43D.

[0271] According to this, the height of the roller 3b of the first shoji screen 3 and the roller (not shown) of the second shoji screen 4 can be adjusted through the roller adjustment holes 137, 147, and even if the relative positional relationship in the vertical direction between the first shoji screen 3 and the second shoji screen 4 changes, the adjustment groove 125 or the adjustment groove 145 can allow displacement of the extension piece 3314. Therefore, it is possible to further facilitate fitting adjustment.

[0272] In the building fixture 1D of this embodiment, the upper end cap 110 further has abutment portions 118a, 118b that protrude in the direction of movement of the first shoji screen 3, and the lower end cap 130 further has abutment portions 138a, 138b that protrude in the direction of movement of the first shoji screen 3.

[0273] As a result, the upper end cap 110 and the lower end cap 130 can function to prevent fingers from getting caught when the screens 3, 4, 5, and 6 move. This eliminates the need to add a separate finger-trap prevention member, thereby reducing manufacturing costs and simplifying the manufacturing process.

[0274] Although the embodiment of the fitting 1D has been described above, the fitting 1D is not limited to the above embodiment and can be modified as appropriate. For example, the configurations of the guide block 9, the upper end caps 110, 120, and the lower end caps 130, 140 are merely examples and can be modified as appropriate depending on the circumstances. Furthermore, the upper end caps 110, 120 and the lower end caps 130, 140 can be omitted from the fitting 1D.

[0275] The building fixture of the present disclosure includes the following aspects.

[0276] <Aspect D1> A fitting having a first shoji screen and a second shoji screen that move on the same rail, and configured so that the first shoji screen and the second shoji screen are closed by butting their leading edge stiles together, wherein the leading edge stile of the first shoji screen has an extension piece that extends from the front surface of the second shoji screen side to the first shoji screen side, and the leading edge stile of the second shoji screen has a stile covering part that protrudes to one side in the front direction and is arranged to cover the front surface of the leading edge stile of the first shoji screen on one side in the front direction when the first shoji screen and the second shoji screen are closed, and an airtight material that is arranged in a recess formed on the front surface of the first shoji screen side, extends to one side in the front direction, and comes into contact with the extension piece when the first shoji screen and the second shoji screen are closed, A building fixture comprising: a guide member that is placed in the recess and has a groove into which the tip of the extension piece is inserted when the first shoji screen and the second shoji screen are closed.

[0277] <Aspect D2> The door-end side vertical frame of the first shoji screen has a first end member arranged at its longitudinal end, and the door-end side vertical frame of the second shoji screen has a second end member arranged at its longitudinal end, and the first end member and the second end member are configured to fit together when the first shoji screen and the second shoji screen are closed, as described in Aspect D1.

[0278] <Aspect D3> The first end member has a first guide groove that sandwiches the rail and is formed to be adjacent to or overlap the extension piece in the prospective direction, and the second end member has a second guide groove that sandwiches the rail, a fixture as described in Aspect D2.

[0279] <Aspect D4> The second end member corresponds to the position of the extension piece when the first shoji screen and the second shoji screen are closed, and has an adjustment groove formed therein that extends toward the end in the longitudinal direction of the door-end vertical frame. This is a fitting according to aspect D3.

[0280] <Aspect D5> The fitting according to any one of aspects D2 to D4, wherein the first end member further has a butt portion that protrudes in the direction of movement of the first shoji screen.

[0281] In the above-mentioned building fixtures 1, 1A, 1B, 1C, and 1D, the first shoji screen 3 slides on the indoor rails 211 and 221, and the vertical frames 33, 33A, 33B, 33C, and 33D on the door end side are arranged to straddle the outdoor rails 212 and 222, but the first shoji screen 3 may slide on the outdoor rails 212 and 222, and the vertical frames 33, 33A, 33B, 33C, and 33D on the door end side may be arranged to straddle the indoor rails 211 and 221.

[0282] The third shoji screen 5 and the fourth shoji screen 6, located at both ends of the fittings 1, 1A, 1B, 1C, and 1D, may be immovably fixed to the frame 2. The fittings 1, 1A, 1B, 1C, and 1D are not limited to fittings in which two shoji screens 3, 4 and two shoji screens 5, 6 are slidably mounted on the inside rails 211, 221 and the outside rails 212, 222, respectively, but may be fittings having shoji screens that slide on either the inside or outside rail.
