[0008] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The fitting of this embodiment is a sliding window 1 attached to a rectangular opening 101 in a building skeleton 100. The sliding window 1 comprises a frame 2 attached to the opening 101, and an outer shoji screen 3 and an inner shoji screen 4 that are slidably housed inside the frame 2 in the horizontal direction. An exterior wall material 110 is provided on the exterior surface X1 of the building skeleton 100 on the outside of the sliding window 1, and an interior wall material 120 is provided on the interior surface X2 of the building skeleton 100.

[0009] Here, the directions in the diagram are defined. X1 indicates the outside side of the sliding window 1, and X2 indicates the inside side of the sliding window 1. The X1-X2 direction indicates the projection direction of the sliding window 1. In the sliding window 1, the surface that is arranged along the projection direction is defined as the projection surface. The direction perpendicular to the projection direction indicates the sight direction of the sliding window 1. In the sliding window 1, the surface that is arranged along the sight direction is defined as the sight surface. In the sight direction, the direction toward the outside of the frame 2 is defined as the outside, and the surface facing outward is defined as the outer surface. In the sight direction, the direction toward the inside of the frame 2 is defined as the inside, and the surface facing inward is defined as the inner surface. In the direction perpendicular to the X1-X2 direction, the direction along the direction of gravity is defined as up and down, and the direction along the width of the sliding window 1 is defined as left and right.

[0010] First, we will explain the frame body 2. The frame body 2 is formed by framing an upper frame 21 extending horizontally above the opening 101, a lower frame 22 extending horizontally below the opening 101, and a pair of left and right vertical frames 23, 24 extending vertically on the left and right vertical portions of the opening 101 in a rectangular shape. A frame member 5 is attached to the interior side X2 of the frame body 2 around all four peripheries in the vertical and left and right vertical directions.

[0011] As shown in Figure 4, the upper frame 21 is divided into an outdoor metal frame member 211 and an indoor metal frame member 212. The outdoor metal frame member 211 and the indoor metal frame member 212 are connected by a bridge member 213 made of heat insulating material such as resin. The upper frame 21 has an outdoor upper rail 21a, an indoor upper rail 21b, and an upper rail 21c for a screen door, each of which protrudes toward the lower frame 22. In this embodiment, the screen door is not shown.

[0012] The outdoor metal frame member 211 has an outer plate portion 211a, an inner plate portion 211b, an outdoor side plate portion 211c, an indoor side plate portion 211d, a frame mounting plate portion 211e, and a partition plate portion 211f. The frame mounting plate portion 211e protrudes outward from the indoor side X2 end portion of the outer plate portion 211a and extends along the extension direction of the upper frame 21. The partition plate portion 211f is formed across the outer plate portion 211a and the inner plate portion 211b and extends along the extension direction of the upper frame 21. As a result, two hollow portions S1a, S1b are formed inside the outdoor metal frame member 211 in the front-to-back direction, separated by the partition plate portion 211f. The outdoor upper rail 21a protrudes inward from a position on the inner plate portion 211b where the partition plate portion 211f is provided. The screen upper rail 21c protrudes inward from the outdoor side X1 end of the outdoor metal frame member 211.

A hollow portion S2a is defined within the outdoor metal frame member 221, surrounded by the outer plate portion 221a, the inner plate portion 221b, the outdoor plate portion 221c, and the indoor plate portion 221d. The frame mounting plate portion 221e protrudes outward from the indoor-side X2 end of the outer plate portion 221a and extends along the extension direction of the bottom frame 22. The outdoor bottom rail 22a protrudes inward from the inner plate portion 221b. The screen bottom rail 22c protrudes inward from the outdoor-side X1 end of the outdoor metal frame member 221.

[0018] The indoor-side metal frame member 222 has an outer plate portion 222a, an inner plate portion 222b, an outdoor-side plate portion 222c, and an indoor-side plate portion 222d. As a result, a hollow portion S2b surrounded by the outer plate portion 222a, the inner plate portion 222b, the outdoor-side plate portion 222c, and the indoor-side plate portion 222d is formed inside the indoor-side metal frame member 222. The indoor-side lower rail 22b protrudes inward from the indoor-side X2 end of the inner plate portion 222b.

[0019] The indoor-side metal frame member 222 has an outdoor-side leg 222e that protrudes outward from the end of the outer panel portion 222a on the outdoor-side X1 side, and an indoor-side leg 222f that protrudes outward from the end of the outer panel portion 222a on the outdoor-side X1 side. An attachment piece 222g that extends toward the indoor-side X2 side is provided at the outer end of the indoor-side leg 222f.

[0020] The lower frame 22 is attached to the exterior side surface 100a of the building structure 100 with screws 220a penetrating the structure mounting plate 221e from the outside X1, with the exterior leg 222e and the interior leg 222f placed on the lower inner surface 101b of the opening 101, and is attached to the lower inner surface 101b of the opening 101 with screws 220b penetrating the mounting piece 222g from the inside.

[0021] An outdoor resin cover 224 is attached between the outdoor lower rail 22a and the indoor lower rail 22b of the bottom frame 22. An indoor resin cover 225 is attached from the indoor side X2 side of the indoor lower rail 22b along the inner plate portion 222b of the indoor metal frame member 222. An angle portion 226 extending toward the indoor side X2 is attached to the inner end of the indoor plate portion 222d of the indoor metal frame member 222. The angle portion 226 is attached with screws 226a to the inner surface 52a of the lower frame member 52 arranged on the indoor side X2 of the bottom frame 22.

[0022] As shown in Figures 6 and 7, the pair of left and right vertical frames 23, 24 have metal frame bodies 231, 241 extending in the front direction, frame mounting plate portions 232, 242 protruding outward from near the center of the front direction on the outer surfaces 231a, 241a of the metal frame bodies 231, 241, and indoor plate portions 233, 243 protruding inward from the end of the metal frame bodies 231, 241 on the indoor side X2. Furthermore, as shown in Figure 6, an engagement protrusion 234 protrudes outward from the inner surface 231b of the metal frame body 231 in the vertical frame 23. The engagement protrusion 234 engages with the door edge stile 33 of the outer shoji screen 3 when closed. As shown in Figure 7, an engagement protrusion 244 protrudes outward from the inner surface 241b of the metal frame body 241 in the vertical frame 24. The engagement protrusion 244 engages with the door edge stile 43 of the inner shoji screen 4 when closed. The body mounting plate portions 232, 242, the indoor side plate portions 233, 243, and the engaging projections 234, 244 extend along the extension direction of the vertical frames 23, 24.

[0023] The vertical frames 23, 24 are attached to the exterior side surface 100a of the building structure 100 by screws 230a, 240a that penetrate the structure mounting plate portions 232, 242 from the outside X1, and are attached to the inner surfaces 101c, 101c of the vertical side of the opening 101 by screws 230b, 240b that penetrate the ends of the metal frame main bodies 231, 241 on the inside X2 from the inside.

[0024] As shown in Fig. 6, a resin cover 235 is attached to the inner surface 231b of the metal frame main body 231 between the outer shoji screen 3 when closed and the indoor side plate portion 233. As shown in Figs. 6 and 7, angle portions 236, 245 extending toward the indoor side X2 are provided on the indoor side plate portions 233, 243 of the vertical frames 23, 24. The angle portions 236, 245 are attached to the inner surfaces 53a, 54a of the vertical frame members 53, 54 arranged on the indoor side X2 of the vertical frames 23, 24 by screws 236a, 245a.

[0025] Next, we will explain the outer shoji screen 3 and the inner shoji screen 4. The outer shoji screen 3 is placed on the outside X1 inside the frame body 2, and is attached across the outside upper rail 21a of the upper frame 21 and the outside lower rail 22a of the lower frame 22. The inner shoji screen 4 is placed on the inside X2 inside the frame body 2, and is attached across the inside upper rail 21b of the upper frame 21 and the inside lower rail 22b of the lower frame 22.

[0026] The outer shoji screen 3 and the inner shoji screen 4 each have a surface material G held inside the frame body 30, 40, which is formed by assembling upper frames 31, 41, lower frames 32, 42, door end frames 33, 43, and outer frame 34 and inner frame 44 into a rectangular shape. The door end frames 33, 43, outer frame 34, and inner frame 44 are vertical frames located on the left and right sides of the outer shoji screen 3 and the inner shoji screen 4. The surface material G in this embodiment is made of double-glazed glass formed by two glass plates G1, G1 with a spacer G2 sandwiched between them. A crescent lock 45 is provided on the visible surface 44a of the inner frame 44. The outer frame 34 is provided with a crescent receiver 35 that engages with the crescent lock 45.

[0027] In this embodiment, the frames 30, 40 of the outer and inner shoji screens 3 and 4 each have a composite structure consisting of a metal interior frame member and a wooden exterior frame member. This makes the sliding window 1 a composite sash. Below, we will explain the structure of the upper frames 31, 41, lower frames 32, 42, door edge frames 33, 43, and the outer and inner frames 34, 44. However, since the upper frames 31, 41, lower frames 32, 42, and door edge frames 33, 43 have the same structure, we will explain them with reference to the common drawings.

[0028] As shown in FIG. 9, the upper frames 31, 41 are made up of metal outdoor frame members 311, 411, resin attachments 312, 412, and wooden indoor frame members 313, 413.

[0029] The outdoor frame members 311, 411 are formed with an outdoor wall portion 311a, 411a, an indoor wall portion 311b, 411b, an inner wall portion 311c, 411c, and an outer wall portion 311d, 411d, and have a rectangular cross section, and have a hollow portion S11 inside.

[0030] The outdoor wall portions 311a, 411a and the indoor wall portions 311b, 411b each extend outward. As a result, the outdoor frame members 311, 411 have outdoor extension portions 311e, 411e and indoor extension portions 311f, 411f. Rail engagement grooves 311g, 411g are formed between the outdoor extension portions 311e, 411e and the indoor extension portions 311f, 411f over the entire length in the extension direction of the upper frames 31, 41. Fin members 311h, 411h that protrude toward the indoor side X2 are attached to the outdoor extension portions 311e, 411e. The fin members 311h, 411h are made of an elastic material such as rubber. The fin members 311h, 411h abut against the outdoor upper rail 21a and the indoor upper rail 21b from the outdoor side X1, thereby ensuring airtightness in the front direction of the upper frames 31, 41.

[0031] The outdoor wall portions 311a, 411a extend inward. As a result, the outdoor frame members 311, 411 have outdoor holding plate portions 311i, 411i that hold the outdoor side X1 surface of the upper end of the surface material G.

[0032] Tapping holes 311j, 411j are formed in the outer wall portions 311d, 411d so as to protrude into the hollow portion S11. Screws (not shown) are driven into the tapping holes 311j, 411j to fasten the upper ends of the door end frames 33, 43, the outer frame 34, and the inner frame 44, which are arranged vertically at both ends of the upper frame 31, 41.

[0033] The attachments 312, 412 are arranged to cover the indoor side X2 facing surface of the outdoor frame members 311, 411 over the entire length of the upper frames 31, 41. The attachments 312, 412 are formed with an outdoor side wall 312a, 412a, an indoor side wall 312b, 412b, an inner side wall 312c, 412c, and an outer side wall 312d, 412d, and have a rectangular cross section, with a hollow portion S12 inside. This gives the attachments 312, 412 excellent strength.

[0034] The outdoor wall portions 312a, 412a are provided with outdoor engagement portions 312e, 412e, 312f, 412f that protrude in an L-shape toward the outdoor side X1. The outdoor engagement portions 312e, 412e are arranged at the inner end portions of the outdoor wall portions 312a, 412a. The outdoor engagement portions 312f, 412f are arranged at the outer end portions of the outdoor wall portions 312a, 412a. The outdoor engagement portions 312e, 412e engage with inner engagement portions 311k, 411k that protrude from the inner end portions of the indoor wall portions 311b, 411b of the outdoor frame members 311, 411 toward the indoor side X2. The outdoor engagement portions 312f, 412f engage with the outer end portions of the indoor extension portions 311f, 411f of the outdoor frame members 311, 411. As a result, the attachments 312, 412 are attached so as to cover the visible surfaces of the outdoor side frame members 311, 411 on the indoor side X2.

[0035] A gap 310, 410 is formed between the indoor side wall 311b, 411b of the outdoor frame member 311, 411 and the outdoor side wall 312a, 412a of the attachment 312, 412. Because the gap 310, 410 and the hollow portion S12 of the attachment 312, 412 are arranged on the indoor side X2 of the metal outdoor frame member 311, 411 of the upper frame 31, 41, heat transfer in the forward direction is suppressed, resulting in excellent insulation properties.

[0036] The indoor-side wall portions 312b, 412b extend inward. As a result, the attachments 312, 412 form indoor-side holding plate portions 312g, 412g that hold the indoor-side X2 surface of the upper end portion of the surface material G. The upper end portion of the surface material G is housed between the outdoor-side holding plate portion 311i, 411i and the indoor-side holding plate portion 312g, 412g via the glazing channel G3.

[0037] An indoor side engaging portion 312h, 412h that protrudes in an L shape toward the indoor side X2 is provided at the inner end of the indoor side holding plate portion 312g, 412g. An indoor side engaging portion 312i, 412i that protrudes in an L shape toward the indoor side X2 is provided at the outer end of the indoor side wall portion 312b, 412b.

[0038] The indoor frame members 313, 413 are long, flat, wooden members. Engagement grooves 3131, 4131 that engage with the indoor engagement portions 312h, 412h of the attachments 312, 412 are formed on the inner peripheral end faces 313a, 413a of the indoor frame members 313, 413, over the entire length of the indoor frame members 313, 413. Engagement grooves 3132, 4132 that engage with the indoor engagement portions 312i, 412i of the attachments 312, 412 are formed on the outer peripheral end faces 313b, 413b of the indoor frame members 313, 413, over the entire length of the indoor frame members 313, 413.

[0039] The indoor side engaging portions 312h, 412h, 312i, 412i of the attachments 312, 412 engage with the engaging grooves 3131, 4131, 3132, 4132 of the indoor side stile members 313, 413. As a result, the indoor side stile members 313, 413 are attached so as to be sandwiched from above and below by the indoor side engaging portions 312h, 412h, 312i, 412i of the attachments 312, 412.

[0040] The indoor side engaging portions 312h, 412h, 312i, 412i cover at least a part of the inner peripheral end faces 313a, 413a and the outer peripheral end faces 313b, 413b of the indoor side frame members 313, 413. More specifically, the indoor side engaging portions 312h, 412h, 312i, 412i cover the outdoor side X1 region from the indoor side wall portions 312b, 412b of the attachments 312, 412 to the inner peripheral end faces 313a, 413a and the outer peripheral end faces 313b, 413b of the indoor side frame members 313, 413. Therefore, the inner and outer peripheral end faces of the indoor side engagement portions 312h, 412h, 312i, 412i form cover portions 312h1, 412h1, 312i1, 412i1 that cover part of the inner peripheral end face 313a, 413a and the outer peripheral end face 313b, 413b of the indoor side frame member 313, 413. An adhesive member such as double-sided adhesive tape (not shown) may be provided between the attachment 312, 412 and the indoor side frame member 313, 413, as necessary.

[0041] As shown in FIG. 10, the lower frames 32, 42 are made up of metal outdoor frame members 321, 421, resin attachments 322, 422, and wooden indoor frame members 323, 423.

[0042] The outdoor frame members 321, 421 are formed with an outdoor wall portion 321a, 421a, an indoor wall portion 321b, 421b, an inner wall portion 321c, 421c, and an outer wall portion 321d, 421d, and have a rectangular cross section, and have a hollow portion S21 inside.

[0043] The outdoor wall portions 321a, 421a and the indoor wall portions 321b, 421b each extend outward. Thus, the outdoor frame members 321, 421 have outdoor extension portions 321e, 421e and indoor extension portions 321f, 421f. Between the outdoor extension portions 321e, 421e and the indoor extension portions 321f, 421f, rail engagement grooves 321g, 421g are formed over the entire length in the extension direction of the lower frames 32, 42. Fin members 321h, 421h that protrude toward the indoor side X2 are attached to the outdoor extension portions 321e, 421e. The fin members 321h, 421h are made of an elastic material such as rubber. The fin members 321h, 421h abut against the outdoor lower rail 22a and the indoor lower rail 22b from the outdoor side X1, thereby ensuring airtightness in the front direction of the lower frames 32, 42.

[0044] The outdoor wall portions 321a, 421a extend inward. As a result, the outdoor frame members 321, 421 have outdoor holding plate portions 321i, 421i that hold the outdoor side X1 surface of the lower end of the face material G.

[0045] Tapping holes 321j, 421j are formed in the inner wall portions 321c, 421c so as to protrude toward the face material G. Screws (not shown) are driven into the tapping holes 321j, 421j to fasten the lower ends of the outer frame 34 and the inner frame 44, which are arranged vertically at both ends of the lower frames 32, 42.

[0046] Door rollers R, R that roll on the outdoor lower rail 22a and the indoor lower rail 22b of the lower frame 22 are disposed in the hollow portion S21 of the outdoor frame members 321, 421. The door rollers R, R protrude from the outdoor wall portions 312d, 421d into the rail engagement grooves 321g, 421g.

[0047] The attachments 322, 422 are arranged to cover the indoor side X2 facing surface of the outdoor frame members 321, 421 over the entire length of the lower frames 32, 42. The attachments 322, 422 are formed with an outdoor side wall 322a, 422a, an indoor side wall 322b, 422b, an inner side wall 322c, 422c, and an outer side wall 322d, 422d, and have a rectangular cross section, with a hollow portion S22 inside. This gives the attachments 322, 422 excellent strength.

[0048] The outdoor wall portions 322a, 422a are provided with outdoor engagement portions 322e, 422e, 322f, 422f that protrude in an L-shape toward the outdoor side X1. The outdoor engagement portions 322e, 422e are arranged at the inner end portions of the outdoor wall portions 322a, 422a. The outdoor engagement portions 322f, 422f are arranged at the outer end portions of the outdoor wall portions 322a, 422a. The outdoor engagement portions 322e, 422e engage with inner engagement portions 321k, 421k that protrude from the inner end portions of the indoor wall portions 321b, 421b of the outdoor frame members 321, 421 toward the indoor side X2. The outdoor engagement portions 322f, 422f engage with the outer end portions of the indoor extension portions 321f, 421f of the outdoor frame members 321, 421. As a result, the attachments 322, 422 are attached so as to cover the visible surfaces of the outdoor side frame members 321, 421 on the indoor side X2.

[0049] Gaps 320, 420 are formed between the indoor wall portions 321b, 421b of the outdoor frame members 321, 421 and the outdoor wall portions 322a, 422a of the attachments 322, 422. Because the gaps 320, 420 and the hollow portions S22 of the attachments 322, 422 are arranged on the indoor side X2 of the metal outdoor frame members 321, 421 of the lower frames 32, 42, heat transfer in the forward direction is suppressed, resulting in excellent thermal insulation.

[0050] The indoor-side wall portions 322b, 422b extend inward. As a result, the attachments 322, 422 form indoor-side holding plate portions 322g, 422g that hold the indoor-side X2 surface of the lower end portion of the surface material G. The lower end portion of the surface material G is housed between the outdoor-side holding plate portion 321i, 421i and the indoor-side holding plate portion 322g, 422g via the glazing channel G3.

[0051] An indoor side engaging portion 322h, 422h that protrudes in an L shape toward the indoor side X2 is provided at the inner end of the indoor side holding plate portion 322g, 422g. An indoor side engaging portion 322i, 422i that protrudes in an L shape toward the indoor side X2 is provided at the outer end of the indoor side wall portion 322b, 422b.

[0052] The indoor frame members 323, 423 are long, flat, wooden members. Engagement grooves 3231, 4231 that engage with the indoor engagement portions 322h, 422h of the attachments 322, 422 are formed on the inner peripheral end faces 323a, 423a of the indoor frame members 323, 423, over the entire length of the indoor frame members 323, 423. Engagement grooves 3232, 4232 that engage with the indoor engagement portions 322i, 422i of the attachments 322, 422 are formed on the outer peripheral end faces 323b, 423b of the indoor frame members 323, 423, over the entire length of the indoor frame members 323, 423.

[0053] The indoor side engaging portions 322h, 422h, 322i, 422i of the attachments 322, 422 engage with the engaging grooves 3231, 4231, 3232, 4232 of the indoor side stile members 323, 423. As a result, the indoor side stile members 323, 423 are attached so as to be sandwiched from above and below by the indoor side engaging portions 322h, 422h, 322i, 422i of the attachments 322, 422.

[0054] The indoor side engaging portions 322h, 422h, 322i, 422i cover at least a part of the inner peripheral end faces 323a, 423a and the outer peripheral end faces 323b, 423b of the indoor side frame members 323, 423. More specifically, the indoor side engaging portions 322h, 422h, 322i, 422i cover the outdoor side X1 region from the indoor side wall portions 322b, 422b of the attachments 322, 422 to the inner peripheral end faces 323a, 423a and the outer peripheral end faces 323b, 423b of the indoor side frame members 313, 413. Therefore, the inner peripheral end faces and outer peripheral end faces of the indoor side engagement portions 322h, 422h, 322i, 422i form cover portions 322h1, 422h1, 322i1, 422i1 that cover part of the inner peripheral end faces 323a, 423a and outer peripheral end faces 323b, 423b of the indoor side frame members 323, 423. An adhesive member such as double-sided adhesive tape (not shown) may be provided between the attachments 322, 422 and the indoor side frame members 323, 423, as necessary.

[0055] As shown in Figure 11, the door end frames 33, 43 are composed of metal outdoor frame members 331, 431, resin attachments 332, 432, and wooden indoor frame members 333, 433. The door end frame 33 of the outer shoji screen 3 and the door end frame 43 of the inner shoji screen 4 are symmetrical on the left and right.

[0056] The outdoor frame members 331, 431 are formed with an outdoor wall portion 331a, 431a, an indoor wall portion 331b, 431b, an indoor wall portion 331c, 431c, and an outdoor wall portion 331d, 431d, and have a rectangular cross section, and have a hollow portion S31 inside. The outdoor wall portions 331a, 431a are formed to be recessed toward the indoor side X2, and form pull handles for opening and closing the outer shoji screen 3 and the inner shoji screen 4 from the outdoor side X1.

[0057] The outer wall portions 331d, 431d have outdoor protrusions 331e, 431e and indoor protrusions 331f, 431f that protrude outward from the ends on the outdoor side X1 and the indoor side X2, respectively. A door-end engagement groove 331g, 431g is formed between the outdoor protrusions 331e, 431e and the indoor protrusions 331f, 431f over the entire length of the door end stiles 33, 43 in the extension direction. Fin members 331h, 431h that protrude toward the indoor side X2 are attached to the outdoor protrusions 331e, 431e. The fin members 331h, 431h are made of an elastic material such as rubber. The fin members 331h, 431h abut against the engaging protrusions 234, 244 of the vertical frames 23, 24 from the inside, thereby ensuring airtightness in the front direction of the door end frames 33, 43.

[0058] The outdoor wall portions 331a, 431a extend inward. As a result, the outdoor frame members 331, 431 have outdoor holding plate portions 331i, 431i that hold the outdoor side X1 surface of the door-tip side end of the surface material G.

[0059] The attachments 332, 432 are arranged to cover the visible surface of the indoor side X2 of the outdoor side frame members 331, 431 over the entire length in the extension direction of the door end frames 33, 43. The attachments 332, 432 have side wall portions 332a, 432a and a hollow portion S32. The hollow portion S32 is arranged on the outdoor side X1 surface at the outer end of the side wall portions 332a, 432a, and is formed into a rectangular cross section by the inner wall portions 332b, 432b, the outer wall portions 332c, 432c, and the outdoor side wall portions 332d, 432d.

[0060] The attachments 332, 432 are provided with outdoor engagement portions 332e, 432e, 332f, 432f that protrude in an L-shape toward the outdoor side X1. The outdoor engagement portions 332e, 432e are located near the inner ends of the side wall portions 332a, 432a. The outdoor engagement portions 332f, 432f are located at the outer ends of the outdoor wall portions 332d, 432d that constitute the hollow portion S3. The outdoor engagement portions 332e, 432e engage with indoor engagement portions 331j, 431j that protrude from the inner ends of the indoor wall portions 331b, 431b of the outdoor frame members 331, 431 toward the indoor side X2. The outdoor engagement portions 332f, 432f engage with the outer ends of the indoor protrusions 331f, 431f of the outdoor frame members 311, 411. As a result, the attachments 332, 432 are attached so as to cover the visible surfaces of the outdoor side frame members 331, 431 on the indoor side X2.

[0061] Gaps 330, 430 are formed between the indoor wall portions 331b, 431b of the outdoor frame members 311, 411 and the side wall portions 332a, 432a of the attachments 332, 432. Because the gaps 330, 430 and the hollow portions S32 of the attachments 332, 432 are arranged on the indoor side X2 of the metal outdoor frame members 331, 431, the door end frames 33, 43 suppress heat transfer in the forward direction and have excellent insulation properties.

[0062] The side walls 332a, 432a extend inward. As a result, the attachments 332, 432 form indoor-side holding plates 332g, 432g that hold the indoor-side X2 surface of the door-leading end of the surface material G. The door-leading end of the surface material G is housed between the outdoor-side holding plates 331i, 431i and the indoor-side holding plates 332g, 432g via the glazing channel G3.

[0063] An indoor side engaging portion 332h, 432h that protrudes in an L shape toward the indoor side X2 is provided at the inner end of the indoor side holding plate portion 332g, 432g. An indoor side engaging portion 332i, 432i that protrudes in an L shape toward the indoor side X2 is provided at the outer end of the inner wall portion 332b, 432b.

[0064] The indoor frame members 333, 433 are long, flat members made of wood. Engagement grooves 3331, 4331 that engage with the indoor engagement portions 332h, 432h of the attachments 332, 432 are formed on the inner peripheral end faces 333a, 433a of the indoor frame members 333, 433, over the entire length of the indoor frame members 333, 433. Engagement grooves 3332, 4332 that engage with the indoor engagement portions 332i, 432i of the attachments 332, 432 are formed on the outer peripheral end faces 333b, 433b of the indoor frame members 333, 433, over the entire length of the indoor frame members 333, 433.

[0065] The indoor side engaging portions 332h, 432h, 332i, 432i of the attachments 332, 432 engage with the engaging grooves 3331, 4331, 3332, 4332 of the indoor side stile members 333, 433. As a result, the indoor side stile members 333, 433 are attached so as to be sandwiched from the left and right by the indoor side engaging portions 332h, 432h, 332i, 432i of the attachments 332, 432.

[0066] The indoor-side engaging portions 332h, 432h, 332i, 432i cover at least a part of the inner peripheral end faces 333a, 433a and the outer peripheral end faces 333b, 433b of the indoor-side frame members 333, 433. More specifically, the indoor-side engaging portions 332h, 432h, 332i, 432i cover the outdoor-side X1 region from the side wall portions 332a, 432a of the attachments 332, 432 to the inner peripheral end faces 333a, 433a and the outer peripheral end faces 333b, 433b of the indoor-side frame members 333, 433. Therefore, the inner and outer peripheral end faces of the indoor engaging portions 332h, 432h, 332i, 432i form covering portions 332h1, 432h1, 332i1, 432i1 that cover part of the inner peripheral end face 333a, 433a and the outer peripheral end face 333b, 433b of the indoor frame member 333, 433. An adhesive member such as double-sided adhesive tape (not shown) may be provided between the attachment 332, 432 and the indoor frame member 333, 433, as necessary.

[0067] The indoor frame members 333, 433 of the door end frames 33, 43 are integrally provided with pull handles 333c, 433c for opening and closing the outer shoji screen 3 and inner shoji screen 4. The pull handles 333c, 433c are formed long along the extension direction of the indoor frame members 333, 433 and protrude toward the indoor side X2. This improves operability for opening and closing the outer shoji screen 3 and inner shoji screen 4. The pull handles 333c, 433c are integral with the indoor frame members 333, 433, and do not have to be connected as would be the case if separate parts were attached, resulting in a good appearance. The bases 333c1, 433c1 of the pull handles 333c, 433c are formed by smoothly continuous inclined surfaces. Therefore, no excessive force is applied to the bases 333c1, 433c1 of the pull tabs 333c, 433c during opening and closing operations, and there is no risk of the pull tabs 333c, 433c being damaged over long-term use.

[0068] As shown in FIG. 8, the outer frame 34 of the outer shoji screen 3 is composed of a metal frame member 341 and a resin frame member 342.

[0069] The metal frame member 341 is formed with an outdoor wall portion 341a, an indoor wall portion 341b, an inner wall portion 341c, and an outer wall portion 341d, and has a rectangular cross section, and has a hollow portion S41a inside.

[0070] The outdoor wall portion 341a extends inward. As a result, the metal frame member 341 has an outdoor holding plate portion 341e that holds the outdoor side X1 surface of the joining side end of the face material G.

[0071] The outer end of the indoor wall portion 341b is provided with an engaging portion 341f bent in an L-shape toward the indoor side X2 and the inside, and a fin member 341g. The fin member 341g is made of an elastic material such as rubber. The fin member 341g abuts against the visible surface of the outdoor side X1 of the inner frame 44 of the inner screen 4 from the outdoor side X1, thereby ensuring airtightness in the visible direction at the indoor side.

[0072] The resin frame member 342 is attached to the inner wall 341c of the metal frame member 341 and protrudes inward on the indoor side X2 of the face material G. The resin frame member 342 has a base 342a attached along the inner wall 341c and an indoor side support plate 342b that protrudes in an L-shape from the base 342a toward the inside and outdoor side X1. The indoor side support plate 342b supports the indoor side X2 surface of the joining side end of the face material G. The joining side end of the face material G is housed between the outdoor side support plate 341e and the indoor side support plate 342b via the glazing channel G3.

[0073] The indoor side support plate portion 342b has a hollow portion S41b that protrudes toward the indoor side X2. As shown in Figure 8, when the outer shoji screen 3 and the inner shoji screen 4 are closed, the resin frame member 342 is exposed between the face material G of the outer shoji screen 3 and the inner frame 44 of the inner shoji screen 4. This suppresses heat transfer in the forward direction of the outer frame 34 of the outer shoji screen 3, resulting in excellent thermal insulation.

[0074] As shown in Figures 8 and 12, the inner frame 44 of the inner shoji screen 4 is composed of a metal outer frame member 441, a resin attachment 442, and a wooden inner frame member 443.

[0075] The outdoor frame member 441 has a rectangular cross section and is made up of an outdoor wall portion 441a, an indoor wall portion 441b, an inner wall portion 441c, an outdoor wall portion 441d, and a partition wall portion 441e. The interior of the outdoor frame member 441 has two hollow portions S42a and S42b that are partitioned in the front direction by the partition wall portion 441e.

[0076] The projection dimension of the inner frame 44 is larger than the projection dimensions of the upper frames 31, 41, lower frames 32, 42, and end frames 33, 43 of the outer shoji 3 and inner shoji 4, because the outdoor frame member 441 has two hollow portions S42a, 42b arranged side by side in the projection direction. Therefore, the inner frame 44 protrudes more from the surface material G toward the indoor side X2 than the upper frames 31, 41, lower frames 32, 42, and end frames 33, 43.

[0077] Specifically, as shown in Figure 13, the visible surface 44c on the indoor side X2 of the joint inner frame 44 protrudes toward the indoor side X2 beyond the position of the end portions of the upper frame 21 and the lower frame 22 closest to the indoor side X2, i.e., the end portions of the indoor side X2 of the indoor side metal frame member 212 of the upper frame 21 and the position of the indoor side plate portion 222d of the indoor side metal frame member 222 of the lower frame 22. The joint inner frame 44 protrudes toward the indoor side X2 in the projection direction to the position of the ends 216b, 226b on the indoor side X2 of the angle portions 216, 226 of the upper frame 21 and the lower frame 22. As a result, the joint inner frame 44 has an indoor side protruding portion 440 that is arranged so as to be sandwiched between the upper and lower angle portions 216, 226.

[0078] The outdoor wall portion 441a is provided with an engagement portion 441f that is bent in an L-shape toward the outdoor side X1 and the inside. As shown in Figure 8, the engagement portion 441f is inserted between the engagement portion 341f of the joining outer frame 34 and the indoor wall portion 341b when the outer frame 3 and the inner frame 44 are closed. This forms a labyrinth, which restricts the flow of air between the joining outer frame 34 and the joining inner frame 44.

[0079] The outdoor wall portion 441a extends inward. As a result, the outdoor frame member 441 has an outdoor holding plate portion 441g that holds the outdoor side X1 surface at the joining side end of the face material G.

[0080] The indoor side wall portion 441b is formed with an engaging portion 441h that is bent in an L shape from the inner end toward the inside and the outdoor side X1.

[0081] The attachment 442 is arranged to cover the indoor-side wall portion 441b, the inner wall portion 441c, and the outer wall portion 441d of the outdoor-side frame member 441 over the entire length in the extension direction of the joining inner frame 44. That is, the attachment 442 has an indoor-side wall portion 442a that covers the indoor-side wall portion 441b of the outdoor-side frame member 441, an inner wall portion 442b that covers the inner wall portion 441c, and an outer wall portion 442c that covers the outer wall portion 441d.

[0082] An engagement portion 442d that protrudes inward is formed on the inner wall portion 442b. An engagement portion 442e that protrudes outward is formed on the end of the outer wall portion 442c facing the outdoor side X1. The engagement portion 442d engages with an engagement portion 441h of the outdoor side frame member 441, and the engagement portion 442e engages with a protrusion 441i formed on the outer end of the outdoor side wall portion 441a of the outdoor side frame member 441. In this way, the attachment 442 is attached so as to cover the visible inner and outer surfaces of the outdoor side frame member 441 and the visible surface on the indoor side X2.

[0083] The outdoor-side X1 end of the inner wall portion 442b is bent outward. As a result, the attachment 442 is formed with an indoor-side holding plate portion 442f that holds the indoor-side X2 surface of the joining-side end of the face material G. The inner end of the indoor-side holding plate portion 442f abuts against the inner wall portion 441c of the outdoor frame member 441. The joining-side end of the face material G is housed between the outdoor-side holding plate portion 441g and the indoor-side holding plate portion 442f via the glazing channel G3.

[0084] An indoor side engaging portion 442g that protrudes in an L shape toward the inside and the indoor side X2 is provided at an end of the indoor side X1 of the indoor wall portion 442b. An indoor side engaging portion 442h that protrudes in an L shape toward the outside and the indoor side X2 is provided at an end of the outdoor side X1 of the outdoor side of the outer wall portion 442c.

[0085] The indoor frame member 443 is divided into a first indoor frame member 4431 and a second indoor frame member 4432, each made of wood. The first indoor frame member 4431 has a shape that covers the entire indoor wall portion 442a and the inner wall portion 442b of the attachment 442 and a part of the outer wall portion 442c. The second indoor frame member 4432 is made of a flat plate-shaped member that covers a part of the outer wall portion 442c of the attachment 442. However, the indoor frame member 443 is not limited to having such a divided structure and may be a one-piece member.

[0086] As shown in Figure 13, the first indoor-side frame member 4431 is provided on the indoor-side protruding portion 440 of the joint inner frame 44. Therefore, the first indoor-side frame member 4431 is arranged so as to be sandwiched between the upper and lower angle portions 216, 226. The vertical length of the first indoor-side frame member 4431 is shorter than the vertical length of the second indoor-side frame member 4432. The vertical distance between the lower end portion 4431a2 of the first indoor-side frame member 4431 and the angle portion 226 of the lower frame 22 is shorter than the vertical distance between the upper end portion 4431a1 of the first indoor-side frame member 4431 and the angle portion 216 of the upper frame 21. Therefore, when the inner frame 44 is viewed from the indoor side X2, the lower end of the inner frame 44 is difficult to see, and the user is strongly impressed with the texture of the wooden indoor frame member 443, resulting in a highly aesthetic design.

[0087] The boundary La where the first indoor-side frame member 4431 and the second indoor-side frame member 4432 butt together is located on the outer wall portion 442c of the attachment 442 and extends along the extension direction of the mating inner frame 44. The boundary La is located on the indoor side X2 of the face material G. As shown in FIG. 12, the boundary La is formed by butting together two inclined surfaces and is located so as to intersect obliquely with the projection direction. That is, the position of the outer edge La1 and the position of the inner edge La2 of the boundary La are offset in the projection direction. Therefore, even if a dimensional change in the projection direction occurs between the first indoor-side frame member 4431 and the second indoor-side frame member 4432 due to shrinkage or the like and the gap at the boundary La becomes larger, the attachment 442 inside is difficult to see through the gap.

[0088] An engagement groove 443a1 that engages with the indoor side engagement portion 442g on the inside of the attachment 442 is formed over the entire length of the indoor side stile member 443 at the outdoor side X1 end of the inner peripheral end face 443a of the indoor side stile member 443. An engagement groove 443b1 that engages with the indoor side engagement portion 442h on the outside of the attachment 442 is formed over the entire length of the indoor side stile member 443 at the outdoor side X1 end of the outer peripheral end face 443b of the indoor side stile member 443. As a result, the indoor side stile member 443 is attached so that it is sandwiched from the left and right by the indoor side engagement portions 442g, 442h of the attachment 442.

[0089] The indoor side engaging portion 442g covers at least a portion of the inner peripheral end face 443a of the indoor side frame member 443. More specifically, the indoor side engaging portion 442g covers the outdoor side X1 region of the inner peripheral end face 443a of the indoor side frame member 443 from the face material G side. Therefore, the inner peripheral end face of the indoor side engaging portion 442g forms a covering portion 442g1 that covers a portion of the inner peripheral end face 443a of the indoor side frame member 443. An adhesive member such as double-sided adhesive tape (not shown) may be provided between the attachment 442 and the indoor side frame member 443, if necessary.

[0090] The upper frames 31, 41, lower frames 32, 42, end frames 33, 43, outer frame 34, and inner frame 44 configured as described above are assembled vertically into a rectangle to form the frame body 30, 40 so that the upper frames 31, 41 and lower frames 32, 42 are positioned between the end frames 33, 43 and the outer frame 34 and inner frame 44. At this time, the indoor frame members 313, 323, 333, 413, 423, 433, 443 of each frame are also assembled vertically into a rectangle.

[0091] Figure 14 shows the connection between the bottom frame 42 and the door end frame 43 of the inner shoji screen 4. The boundary Lb between the indoor frame members 423, 433 assembled by vertical insertion is configured by butting inclined surfaces, similar to the boundary La between the first indoor frame member 4431 and the second indoor frame member 4432 of the joining inner frame 44. Therefore, even if a dimensional change in the visible direction due to shrinkage or other factors occurs between the indoor frame member 423 of the bottom frame 42 and the indoor frame member 433 of the door end frame 43, causing the gap at boundary Lb to become larger, it is difficult to visually see the interior through the gap. This configuration of the boundary where inclined surfaces butt together applies equally to all boundaries between indoor frame members in the outer shoji screen 3 and the inner shoji screen 4.

[0092] By constructing the frame bodies 30, 40, the attachments 312, 322, 332, 412, 422, 432, 442 and the indoor frame members 313, 323, 333, 413, 423, 433, 443 of the outer shoji 3 and inner shoji 4 are also arranged to surround the outer periphery of the surface material G all around. In this case, in particular, a portion of the inner peripheral end face 313a, 323a, 333a, 413a, 423a, 433a, 443a of the indoor side frame member 313, 323, 333, 413, 423, 433, 443 is covered all around by the cover portion 312h1, 322h1, 332h1, 412h1, 422h1, 432h1, 442g1 of the attachment 312, 322, 332, 412, 422, 432, 442. Therefore, even if condensation occurs on the indoor side X2 surface of the face material G, the indoor side frame member 313, 323, 333, 413, 423, 433, 443 is less likely to come into contact with the condensed water, and deterioration due to contamination, corrosion, etc. caused by the condensed water is suppressed. In particular, even if condensed water flows down the surface of the surface material G, it remains on the cover portions 322h1, 422h1 of the attachments 322, 422 of the lower frames 32, 42, and is unlikely to spread onto the inner peripheral end faces 323a, 423a of the indoor frame members 323, 423.

[0093] The shapes of the cover portions of the attachments 312, 322, 332, 412, 422, 432, 442 are not limited to those shown in Figures 9 to 12, and can be formed into various shapes to more suitably prevent condensation water from wetting and spreading onto the indoor frame members 313, 323, 333, 413, 423, 433, 443.

[0094] 15 to 18 show modified examples of the cover portions of the attachments 322, 422 in the lower frames 32, 42. The configuration other than the cover portions is the same as that of the lower frames 32, 42 shown in FIG.

[0095] The cover portions 322h2, 422h2 shown in Fig. 15 have inclined surfaces that slope from the indoor side X2 toward the outdoor side X1 toward the outer periphery of the frame body 30, 40. That is, the surfaces of the cover portions 322h2, 422h2 of the lower frame 32, 42 slope downward from the indoor side X2 toward the outdoor side X1. This makes it difficult for condensation water that has flowed down the lower frame 32, 42 to flow over the cover portions 322h2, 422h2 to the indoor side X2. Fig. 15 shows an example in which a portion of the cover portions 322h2, 422h2 protrudes inward beyond the indoor side frame member 323, 423, but the cover portions 322h2, 422h2 do not have to protrude inward beyond the indoor side frame member 323, 423. That is, the indoor side X2 of the cover portions 322h2, 422h2 may be entirely covered by the indoor side frame members 323, 423 so as not to be visible from the indoor side X2.

[0096] The cover portions 322h3, 422h3 shown in Fig. 16 have ribs LB. The ribs LB are located at the ends of the cover portions 322h3, 422h3 on the indoor side X2 and protrude inward. That is, the cover portions 322h3, 422h3 of the lower frames 32, 42 have ribs LB that rise upward. This also effectively prevents condensation water that has flowed down the lower frames 32, 42 from overflowing the cover portions 322h2, 422h2 and flowing out to the indoor side X2. Fig. 16 shows an example in which a portion of the cover portions 322h3, 422h3 protrudes inward beyond the indoor side frame members 323, 423, but the cover portions 322h3, 422h3 do not have to protrude inward beyond the indoor side frame members 323, 423. That is, the indoor side X2 of the cover portions 322h3, 422h3 may be entirely covered by the indoor side frame members 323, 423 so as not to be visible from the indoor side X2.

[0097] 17 is formed by a recessed groove. That is, the cover portions 322h4, 422h4 of the lower frames 32, 42 are formed as grooves recessed downward. In this case, condensation water that flows down to the lower frames 32, 42 can be temporarily stored inside the cover portions 322h4, 422h4. Therefore, even if a large amount of condensation water is generated, it is even less likely to flow out to the indoor side X2 than the cover portions 322h4, 422h4.

[0098] 18 cover the entire inner peripheral end faces 323a, 423a of the indoor side frame members 323, 423. Therefore, the indoor side frame members 323, 423 are not likely to come into direct contact with condensation water that has flowed down to the lower frames 32, 42.

[0099] The configurations of the cover portions 322h2, 422h2 to 322h5, 422h5 shown in Figures 15 to 18 can also be applied to the cover portions of the attachments 312, 412, 332, 432, 442 of the upper frames 31, 41, the end frames 33, 43, and the inner frame 44, as necessary.

[0100] End caps are attached to the upper and lower ends of the outer frame 34 of the outer shoji screen 3 and the inner frame 44 of the inner shoji screen 4. The end caps are, for example, anti-vibration components that suppress the vibration of the shoji screen. Figures 13, 19, and 20-22 show the upper anti-vibration component 6 attached to the upper end of the inner frame 44 of the inner shoji screen 4. Figures 13, 21, and 23-25 ​​show the lower anti-vibration component 7 attached to the lower end of the inner frame 44. Both the upper anti-vibration component 6 and the lower anti-vibration component 7 are made of resin and are made of a different material from the wooden indoor frame member 443 that forms the indoor side X2 surface of the inner frame 44. The upper anti-vibration component 6 and the lower anti-vibration component 7 will be explained below.

[0101] The upper anti-vibration component 6 is inserted into and attached to the upper end opening 44d1 of the joint inner frame 44. The upper anti-vibration component 6 has an anti-vibration component main body 61, an end plate portion 62, a sight plate portion 63, and an upper end sealing plate portion 64.

[0102] The anti-vibration component body 61 has a planar shape corresponding to the planar shape of the inner frame 44 and surrounds it on all four sides. The anti-vibration component body 61 abuts against and covers the inner frame 44 from above, so that it is exposed at the upper end of the inner frame 44, as shown in Figure 13. The anti-vibration component body 61 has a groove 611 that opens to the upper surface 61a. The groove 611 is U-shaped in cross section and extends left and right of the inner frame 4 along the extension direction of the upper frame 41, penetrating the anti-vibration component body 61 in the left and right direction. As shown in Figure 13, the groove 611 engages with the indoor upper rail 21b of the upper frame 21 when the inner frame 4 is placed within the frame body 2. A number of locking plates 612 protrude downward from the underside of the anti-vibration component body 61. As shown in Figure 20, the anti-vibration component main body 61 has a locking claw portion 613 on the underside at a position on the outside X1 side of the underside and on the visible surface 44a side of the joint inner frame 44.

[0103] The end plate portion 62 has a semicircular lower end and extends downward along the depth direction of the groove portion 611 from the anti-vibration component main body 61 exposed on the visible surface 44a of the joint inner stile 44. The groove portion 611 penetrates the end plate portion 62 and opens to the visible surface 44a of the joint inner stile 44. Two openings 621, 622 are formed in the end plate portion 62, one above the other. The upper opening 621 is a hole through which a screw SC1 is inserted to secure the outdoor stile member 441 of the joint inner stile 44 to the outdoor stile member 411 of the upper stile 41. The screw SC1 is a fastener that secures the vertical and horizontal stiles together. The screw SC1 is inserted through the opening 621, passes through a screw hole 441c1 formed in the upper end of the inner wall portion 441c of the outdoor frame member 441, and is screwed into a tapping hole 411j formed in the outdoor frame member 411 of the upper frame 41. A blind cap 62a is attached to each of the two openings 621, 622.

[0104] The sight plate portion 63 extends downward along the indoor side X2 surface of the sway prevention component main body 61. The sight plate portion 63 is exposed from the upper end of the joint inner frame 44 and forms the indoor side X2 sight surface of the sway prevention component 6. The left-right width of the sight plate portion 63 corresponds to the left-right width of the indoor side X2 sight surface 44c of the joint inner frame 44.

[0105] The upper end sealing plate portion 64 is made of a rectangular plate-like member and protrudes from the lower end of the sight plate portion 63 toward the indoor side X2. The outer shape of the upper end sealing plate portion 64 corresponds to the planar shape of the rectangular upper end opening 4431c1 that opens at the upper end of the first indoor side stile member 4431 in the joint inner stile 44. The upper end sealing plate portion 64 has a rectangular flat plate portion 641 and a rising portion 642 that rises downward from the flat plate portion 641 along the outer periphery of the flat plate portion 641.

[0106] As shown in Figure 21, the upper sway prevention component 6 has multiple locking plates 612 inserted into the upper end opening 44d1 from above the inner frame 44. The multiple locking plates 612 clamp the partition wall portion 441e of the outdoor frame member 441. The locking claw portion 613 locks onto the protrusion 441i located at the outdoor side X1 end of the outdoor frame member 441. In this way, the upper sway prevention component 6 is attached to the upper end of the inner frame 44.

[0107] 13 and 19, U-shaped cutouts 441j and 4432a capable of accommodating the end plate 62 are formed at the upper end of the outer wall 441d of the outdoor frame member 441 and the upper end of the second indoor frame member 4432 in the joint inner frame 44. When the upper anti-vibration component 6 is attached to the joint inner frame 44, the end plate 62 is accommodated in the cutouts 441j and 4432a and is exposed to the visible surface 44a of the joint inner frame 44.

[0108] As shown in Figures 21 and 22, the upper end sealing plate portion 64 is inserted into the upper end opening 4431c1 of the first indoor-side frame member 4431. The upper end sealing plate portion 64 is arranged flush with the upper end surface 4431d1 of the first indoor-side frame member 4431 and seals the upper end of the outdoor-side frame member 441. This prevents dust and other particles from entering the indoor-side frame member 443. As shown in Figure 21, the rising portion 642 of the upper end sealing plate portion 64 abuts against the upper end 442i1 of the attachment 442 from above within the upper end opening 4431c1 of the first indoor-side frame member 4431.

[0109] 13 and 19, the visible surface 44a of the joint inner frame 44 has end extensions 44a1, 44a1 extending on both sides of the position of the screw SC1. The end extensions 44a1, 44a1 extend to the outdoor and indoor sides of the openings 621, 721 of the end plate portion 62. More specifically, the visible surface 44a of the joint inner frame 44 has a pair of end extensions 44a1, 44a1 extending toward the outside (upward) of the frame body 40 along the visible surface 44a so as to sandwich the end plate portion 62 exposed in the cutout portion 4432a from the outdoor side X1 and the indoor side X2. The pair of end extensions 44a1, 44a1 extend outside (upward) the frame 40 above the height position of the upper opening 621 of the end plate 62, i.e., above the height position of the screw fastening point by the screw SC1. As a result, only the protrusion 614 of the upper sway prevention component 6 and the end plate 62 with the concealing cap 62a attached are visible at the upper end of the visible surface 44a, as shown in FIG. 13. The visible surface 44a of the joint inner frame 44 is not covered by the upper sway prevention component 6. Moreover, as shown in FIG. 13, the sway prevention component main body 61 of the upper sway prevention component 6 is positioned outside (upward) the position of the angle portion 216, which is the innermost end position of the upper frame 21 on the indoor side X2. Therefore, the upper sway prevention component 6 is less noticeable, resulting in excellent design. Since the concealing cap 62a is attached to the end plate portion 62 of the upper anti-vibration component 6, it is less susceptible to dimensional changes in the opening due to shrinkage, etc., compared to when an opening is created in the wooden outdoor frame component 441 and the concealing cap 62a is attached.

[0110] As shown in Figure 22, the anti-vibration component body 61 has a protruding portion 614 that protrudes a predetermined protrusion amount D beyond the projection surface 44a of the joining inner frame 44. As shown in Figure 13, the protruding portion 614 is arranged on the same plane as the projection surface 44a of the joining inner frame 44 when the upper anti-vibration component 6 is attached to the joining inner frame 44. The protruding portion 614 protrudes beyond the projection surface 44a of the joining inner frame 44 on the outer periphery (upper side) of the pair of end extension portions 44a1, 44a1. When the inner sash 4 moves in the opening direction, the protruding portion 614 abuts against an upper stopper member (not shown) that is arranged at the corner between the upper frame 21 and the vertical frame 23. This prevents the second indoor frame member 4432, which forms the projection surface 44a, from coming into direct contact with the upper stopper member, so that even if the inner shoji screen 4 collides with the vertical frame 23 with great force, there is no risk of the upper end of the indoor frame member 443 being damaged.

[0111] The lower anti-vibration component 7 is inserted into and attached to the lower end opening 44d2 of the joint inner frame 44. The lower anti-vibration component 7 has an anti-vibration component main body 71, an end plate portion 72, and a condensation water tray 73.

[0112] Like the anti-vibration component body 61 of the upper anti-vibration component 6, the anti-vibration component body 71 has a planar shape corresponding to the planar shape of the inner frame 44. The anti-vibration component body 71 abuts against and covers the inner frame 44 from below, so that it is exposed at the lower end of the inner frame 44, as shown in Figure 13. The anti-vibration component body 71 has a groove 711 that opens to the underside 71a. The groove 711 is formed in a downward U-shape in cross section, extends left and right of the inner frame 4 along the extension direction of the lower frame 42, and penetrates the anti-vibration component body 71 left and right. As shown in Figure 13, the groove 711 engages with the indoor lower rail 22b of the lower frame 22 when the inner frame 4 is installed within the frame body 2. Multiple locking plates 712 protrude upward from the top surface of the anti-vibration component body 71. As shown in Fig. 24, the anti-sway component main body 71 has a locking claw portion 713 on the upper surface side at a position on the outdoor side X1 and on the visible surface 44a side of the inner frame 44. As shown in Figs. 23 and 25, the underside 71a of the anti-sway component main body 71 has a drainage hole 714 formed therein to drain condensation water received in the anti-sway component main body 71 onto the lower frame 22. A plurality of drainage holes 714 are provided on the underside 71a, with the groove portion 711 sandwiched therebetween.

[0113] The end plate portion 72 has a semicircular upper end and extends upward along the depth direction of the groove portion 711 from the anti-vibration component main body 71 exposed on the visible surface 44a of the joint inner stile 44. The groove portion 711 penetrates the end plate portion 72 and opens to the visible surface 44a of the joint inner stile 44. Two openings 721, 722 are formed in the end plate portion 72, one above the other. The upper opening 721 is a hole through which a screw SC2 is inserted to secure the outdoor stile member 441 of the joint inner stile 44 to the outdoor stile member 421 of the lower stile 42. The screw SC2 is a fastener that secures the vertical and horizontal stiles together. As shown in Figures 21 and 23, the screw SC2 passes through the opening 721 and a screw hole 441d1 formed in the lower end of the outer wall portion 441d of the outer frame member 441, and is screwed into a tapping hole 421j formed in the outer frame member 421 of the bottom frame 42. The lower opening 722 is a hole through which an adjustment tool is inserted when adjusting the door roller R provided on the bottom frame 42. As shown in Figures 21 and 23, insertion holes 441c2 and 441d2 through which the adjustment tool is inserted are formed in the lower ends of the inner wall portion 441c and the outer wall portion 441d of the outer frame member 441. A blind cap 72a is attached to each of the two openings 721 and 722.

[0114] The condensation water tray 73 is a rectangular plate-shaped member that, like the upper sealing plate 64 of the upper sway brace component 6, protrudes from the upper end of the indoor-side X2 surface of the sway brace component main body 71 toward the indoor-side X2. The external shape of the condensation water tray 73 corresponds to the planar shape of the rectangular lower-end opening 4431c2 that opens at the lower end of the first indoor-side stile member 4431 of the inner stile 44. The condensation water tray 73 has a rectangular receiving surface portion 731 and a rising portion 732 that rises upward from the receiving surface portion 731 along the outer periphery of the receiving surface portion 731. The receiving surface portion 731 is formed by an inclined surface that slopes downward from the indoor-side X2 toward the outdoor-side X1. As shown in FIG. 24, the rising portion 732 is not formed on the end 731a of the receiving surface portion 731 on the outdoor-side X1 side, and it opens toward the interior of the sway brace component main body 71.

[0115] As shown in Figure 21, the lower anti-sway component 7 has multiple locking plates 712 inserted into the lower end opening 44d2 from below the inner frame 44. The multiple locking plates 712 clamp the partition wall portion 441e of the outdoor frame member 441. The locking claw portion 713 locks onto the protrusion 441i located at the outdoor side X1 end of the outdoor frame member 441. In this way, the lower anti-sway component 7 is attached to the lower end of the inner frame 44.

[0116] 13 and 23, a U-shaped cutout 4432b capable of accommodating the end plate 72 is formed in the lower end of the second indoor frame member 4432 in the joint inner frame 44. As shown in FIG. 23, the cutout 4432b faces the screw hole 441d1 and the insertion hole 441d2 formed in the outer wall portion 441d of the outdoor frame member 441. When the lower vibration prevention component 7 is attached to the joint inner frame 44, the end plate 72 is accommodated in the cutout 4432b and is exposed to the visible surface 44a of the joint inner frame 44.

[0117] As shown in Figures 21 and 25, the condensation water tray 73 is inserted into the lower end opening 4431c2 of the first indoor-side frame member 4431. The entire receiving surface 731 and rising portion 732 of the condensation water tray 73 are not exposed to the indoor side X2. In other words, the indoor side X2 of the receiving surface 731 and rising portion 732 of the condensation water tray 73 faces the visible surface 44c of the inner frame 44 (is covered by the visible surface 44c) and is configured so as not to be visible from the indoor side X2. The condensation water tray 73 is disposed flush with the lower end surface 4431d2 of the first indoor-side frame member 4431 and seals the lower end of the outdoor frame member 441. Therefore, the condensation water tray 73 also functions as a lower end sealing plate that seals the lower end of the outdoor frame member 441. As shown in FIG. 21, the rising portion 732 of the condensation water receiver 73 abuts against the lower end portion 442i2 of the attachment 442 from below within the lower end opening 4431c2 of the first indoor side frame member 4431.

[0118] As shown in Figure 21, the indoor side surface 441b1 of the indoor wall portion 441b of the outdoor frame member 441 is positioned above the receiving surface portion 731 on the outdoor side X1, higher than the rising portion 732 of the condensation water receiver 73. In other words, the receiving surface portion 731 is positioned on the lower end side of the outdoor frame member 441 and protrudes toward the indoor side X2 further than the indoor side surface 441b1 of the outdoor frame member 441. Therefore, the receiving surface portion 731 can receive condensation water that has formed on and flowed down the indoor side surface 441b1 of the indoor wall portion 441b. The condensation water received by the receiving surface portion 731 flows from the inclined receiving surface portion 731 into the anti-vibration component main body 71 and is discharged onto the lower frame 22 through the drainage hole 714 opening in the underside 71a of the anti-vibration component main body 71. The condensation water receiver 73 receives condensation water on the outdoor side X1 rather than the attachment 442, so the condensation water does not come into contact with the outdoor side X1 surface of the indoor side frame member 443. Therefore, there is no risk of the indoor side frame member 443 being soiled or deteriorated due to corrosion or the like by the condensation water. Note that the water received by the receiving surface portion 731 of the condensation water receiver 73 is not limited to condensation water, but also includes water such as rainwater adhering to the indoor side surface 441b1 of the indoor side wall portion 441b.

[0119] 13 and 23, the visible surface 44a of the joint inner frame 44 has a pair of end extensions 44a2, 44a2 that extend along the visible surface 44a toward the outside (downward) of the frame body 40, sandwiching the end plate portion 72 exposed in the cutout portion 4432b from the outside side X1 and the inside side X2. The pair of end extensions 44a2, 44a2 extend toward the outside (downward) of the frame body 40 above the height position of the upper opening 721 of the end plate portion 72, i.e., the height position of the screw fastening point with the screw SC2. As a result, as shown in FIG. 13, only the protrusion 715 of the lower vibration prevention component 7 and the end plate portion 72 with the blind cap 72a attached are visible at the lower end of the visible surface 44a. Furthermore, as shown in Figure 13, the vibration-preventing component body 71 of the lower vibration-preventing component 7 is positioned outside (lower than) the position of the angle portion 226, which is the innermost position on the indoor side X2 of the lower frame 22. This makes the lower vibration-preventing component 7 less noticeable, resulting in excellent design. Because the concealing cap 72a is attached to the end plate portion 72 of the lower vibration-preventing component 7, it is less susceptible to dimensional changes in the opening due to shrinkage, etc., compared to when an opening is made in the wooden outdoor frame member 441 and the concealing cap 72a is attached.

[0120] Furthermore, as shown in FIG. 13, the joint inner frame 44 has an indoor protrusion 440 that is positioned so as to be sandwiched between the upper and lower angle portions 216, 226. The visible surface 44c of the joint inner frame 44 on the indoor side X2, which is the visible surface of the indoor protrusion 440, extends to the same position as the lower ends of the end extensions 44a2, 44a2. As a result, the lower end 4431a2 of the first indoor side frame member 4431, which is the surface material of the indoor protrusion 440, is close to the angle portion 226 of the lower frame 22 with a small gap between it and the angle portion 226. When the joint inner frame 44 is observed from the indoor side X2, the lower sway-stop component 7 is hidden by the visible surface 44c and is difficult to see, so the impression created by the texture of the wooden indoor side frame member 443 is not marred and the design is excellent.

[0121] As shown in Figure 25, the anti-vibration component body 71, like the anti-vibration component body 61 of the upper anti-vibration component 6, has a protruding portion 715 that protrudes by a predetermined protrusion amount D beyond the projection surface 44a of the joining inner frame 44. As shown in Figure 13, when the lower anti-vibration component 7 is attached to the joining inner frame 44, the protruding portion 715 is arranged on the same plane as the projection surface 44a of the joining inner frame 44. The protruding portion 715 protrudes beyond the projection surface 44a of the joining inner frame 44 on the outer periphery (lower side) of the pair of end extension portions 44a2, 44a2. When the inner sash 4 moves in the opening direction, the protruding portion 715 abuts against a lower stopper member (not shown) arranged at the corner between the lower frame 22 and the vertical frame 23. This prevents the second indoor frame member 4432, which forms the projection surface 44a, from coming into direct contact with the lower stopper member, so that even if the inner shoji screen 4 collides with the vertical frame 23 with great force, there is no risk of the lower end of the indoor frame member 443 being damaged.

[0122] The sliding window 1, which is a fixture of this embodiment, has the following effects: The sliding window 1 houses an outer shoji screen 3 and an inner shoji screen 4, each having an upper frame 31, 41, a lower frame 32, 42, a door edge frame 33, 43, an outer frame 34, and an inner frame 44, which are assembled vertically and horizontally, and the inner frame 44 has an outer frame member 441, an inner frame member 443 arranged on the indoor side X2 of the outer frame member 441, and a condensation water tray 73 that collects condensation water adhering to the outer shoji screen 3 and the inner shoji screen 4, and the condensation water tray 73 is arranged between the outer frame member 441 and the indoor frame member 443, and is not exposed to the indoor side X2.

[0123] This makes it possible to provide a sliding window 1 with a high level of design, since the condensation water tray 73 cannot be seen from the indoor side X2.

[0124] In this embodiment, the condensation water receiver 73 has a receiving surface portion 731 that receives condensation water and a rising portion 732 that rises from the periphery of the receiving surface portion 731, and the receiving surface portion 731 is an inclined surface that slopes downward toward the outside side X1.

[0125] This allows the condensation water received by the receiving surface portion 731 to be smoothly drained to the outside of the room X1, so there is no risk of the indoor side frame member 443 coming into contact with the condensation water.

[0126] In this embodiment, the receiving surface portion 731 is disposed on the lower end side of the outdoor frame member 441, and protrudes further toward the indoor side X2 than the indoor side surface 441b1 of the outdoor frame member 441.

[0127] This allows the receiving surface portion 731 to reliably receive condensation water generated on the indoor side surface 441b1 of the outdoor frame member 441, and allows the function of receiving condensation water to be fully fulfilled.

[0128] In this embodiment, a lower anti-sway component 7 is attached to the lower end of the inner frame 44, which is the vertical frame of the upper frame 31, 41, lower frame 32, 42, door end frame 33, 43, outer frame 34, and inner frame 44, which are assembled vertically and horizontally, and a condensation water tray 73 is provided on the lower anti-sway component 7.

[0129] According to this, by attaching the lower anti-vibration part 7 to the inner frame 44, one part of the lower anti-vibration part 7 can perform the functions of anti-vibration and condensation water collection.

[0130] In this embodiment, the outdoor frame member 441 is made of metal.

[0131] Since the outdoor frame member 441 is made of metal, condensation water is likely to occur on its indoor side surface 441b1, and therefore the effect of receiving the condensation water in the condensation water receiver is more effectively achieved.

[0132] In this embodiment, the indoor frame member 443 is made of wood.

[0133] This allows you to enjoy the design of the wood texture from the indoor side X2 of the sliding window 1, and there is no risk of the indoor side frame member getting wet with condensation water, and there is no risk of the indoor side frame member getting soiled by condensation water.

[0134] In this embodiment, the condensation water receiver 73 is made of resin.

[0135] This makes it difficult for condensation water to form in the condensation water receiver 73 itself.
