Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, wooden sashes have been known in which an opening window with a wooden frame is housed inside a wooden frame installed in an opening in a building skeleton (see, for example, Patent Document 1). In these wooden sashes, an aluminum clad is screwed to the wooden frame from the outer surface of the wooden frame, and then the aluminum clad integrated with the wooden frame is screwed to the building skeleton.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-120127 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional wooden sashes, the heads of the screws that connect the wooden frame and aluminum clad are located on the outer surface of the aluminum clad, facing the inner periphery of the opening in the building frame. Therefore, when the wooden frame needs to be replaced due to factors such as aging, the aluminum clad that integrates the wooden frame must be removed from the building frame. In this case, the wall material must be demolished to expose the fixed parts of the aluminum clad, making the replacement work large-scale and complicated. In addition, the wall material must be re-installed after the replacement, which increases the replacement cost.

[0005] The present disclosure aims to provide a fixture that allows replacement of the wooden frame without the need to demolish the wall material. [Means for solving the problem]

[0006] The present disclosure relates to a fitting comprising a wooden frame attached to an opening in a building skeleton, a shoji screen placed inside the wooden frame, and an attachment positioned between the outer surface of the wooden frame and the inner surface of the opening and fixed to the building skeleton, wherein the wooden frame is fixed to the attachment by screws driven from the inside of the wooden frame.

[0008] Hereinafter, each embodiment of the present disclosure will be described in detail with reference to the drawings. Figures 1 to 8 show a fitting according to a first embodiment. This fitting is a double sliding window 1 to be attached to a rectangular opening 101 formed in a building skeleton 100.

[0009] The sliding window 1 is composed of a wooden frame 2 placed inside the opening 101, an attachment 3 placed between the wooden frame 2 and the building skeleton 100, a frame member 4 placed on the indoor side X2 of the wooden frame 2, an outer shoji screen 5 and an inner shoji screen 6 placed inside the wooden frame 2 so as to be slidable laterally, and a single screen 7 placed on the outdoor side X1 of the outer shoji screen 5 so as to be slidable laterally. An exterior wall material 110 is provided on the outdoor side X1 of the building skeleton 100 outside the wooden frame 2, and an interior wall material 120 is provided on the indoor side X2 of the building skeleton 100. The screen 7 is not shown in Figure 1.

[0010] Here, the directions in the diagram will be 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 is the indoor-outdoor direction of the sliding window 1 and indicates the front direction. In the sliding window 1, the surface that is arranged along the front direction is defined as the front face. The direction perpendicular to the front direction indicates the front direction of the sliding window 1. In the sliding window 1, the surface that is arranged along the front direction is defined as the front face. In the front direction, the outside of the wooden frame 2 is defined as the outside, and the inside of the wooden frame 2 is defined as the inside. The surface facing outward is defined as the outer face, and the surface facing inward is defined as the inner face.

[0011] First, we will explain the wooden frame 2 that is attached to the inside of the opening 101. The wooden frame 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape. The wooden frame 2 has a vertically-opening structure in which the upper frame 21 and the lower frame 22 are placed inside the left and right vertical frames 23, 24. There are no particular restrictions on the type of wood used for the wooden frame 2.

[0012] 4 and 5, the upper frame 21 has an upper frame body 210, an outdoor rail 211, an indoor rail 212, a screen door rail 213, and an attachment piece 214. The outdoor rail 211, the indoor rail 212, the screen door rail 213, and the attachment piece 214 are each made of an extruded shape formed from a metal material such as aluminum, and extend along the length of the upper frame body 210.

[0013] The upper frame body 210 is made of wood and has a generally rectangular cross section. The inner surface 210a and outer surface 210b of the upper frame body 210 are formed flat along the indoor-outdoor direction. The outdoor facing surface 210c and the indoor facing surface 210d of the upper frame body 210 are each formed flat along the vertical direction of the sliding window 1.

[0014] As shown in Fig. 5, the outdoor rail 211 and the indoor rail 212 are each composed of bases 2111, 2121 and a pair of rail pieces 2112, 2112, 2122, 2122 that protrude downward from the bases 2111, 2121. The bases 2111, 2121 protrude further in the indoor / outdoor direction than the pair of rail pieces 2112, 2112, 2122, 2122. As shown in Fig. 5, a pair of mounting grooves 2101, 2102 that extend parallel to each other along the length of the upper frame main body 210 are provided on the inner surface 210a of the upper frame main body 210. The outdoor rail 211 and the indoor rail 212 are each attached to the upper frame main body 210 with screws (not shown) with the bases 2111, 2121 accommodated in the mounting grooves 2101, 2102, respectively. As a result, the outdoor rail 211 and the indoor rail 212 protrude inward from the inner surface 210a of the upper frame body 210 at the same height.

[0015] The screen door rail 213 is positioned on the outermost side X1, and as shown in Figure 5, is composed of an L-shaped rail piece 2131 that extends toward the inside of the upper frame 21 and the indoor side X2, and an overhanging piece 2132 that overhangs outward from the rail piece 2131. The screen door rail 213 is attached to the outdoor facing surface 210c of the upper frame main body 210 with a screw 213a that passes through the overhanging piece 2132, with the overhanging piece 2132 abutting against the outdoor facing surface 210c. The rail piece 2131 protrudes inward beyond the inner surface 210a of the upper frame main body 210.

[0016] The mounting piece 214 is disposed at the end of the upper frame 21 on the indoor side X2. The longitudinal length of the mounting piece 214 is the same as the longitudinal length of the upper frame main body 210. As shown in FIG. 5 , the mounting piece 214 is integrally formed with a base plate portion 2141, an L-shaped mounting plate portion 2142 extending from the end of the base plate portion 2141 on the indoor side X2 toward the outside and the indoor side X2, and a bent piece portion 2143 formed by bending the end of the base plate portion 2141 on the outdoor side X1 toward the outside. A plurality of screw holes 2142a are formed in the mounting plate portion 2142 along the longitudinal direction.

[0017] A cutout portion 2103 having a rectangular cross section is formed at the end of the outer surface 210b of the upper frame body 210 facing the indoor side X2, spanning from the outer surface 210b to the indoor side facing surface 210d. The cutout portion 2103 is an attachment portion for the mounting piece 214 and extends the entire length of the upper frame body 210. The width of the base plate portion 2141 in the indoor-outdoor direction corresponds to the width of the cutout portion 2103 in the indoor-outdoor direction. The protruding height of the mounting plate portion 2142 extending outward from the base plate portion 2141 is greater than the protruding height of the bent piece portion 2143 extending outward from the base plate portion 2141. The protruding height of the bent piece portion 2143 corresponds to the depth of the cutout portion 2103 extending inward from the outer surface 210b of the upper frame body 210.

[0018] The mounting piece 214 is attached to the upper frame body 210 by screws 214a that penetrate the base plate portion 2141, with the base plate portion 2141 and the bent piece portion 2143 abutting against the cutout portion 2103. The screws 214a are provided at multiple locations along the length of the mounting piece 214. As a result, the mounting plate portion 2142 of the mounting piece 214 protrudes outward from the outer surface 210b of the upper frame body 210 and protrudes toward the indoor side X2 from the indoor-side facing surface 210d of the upper frame body 210. The head of the screw 214a is positioned within the cutout portion 2103 and does not protrude from the outer surface 210b of the upper frame body 210.

[0019] 6 and 7, the lower frame 22 has a lower frame main body 220, a rail frame 221, and mounting pieces 222. The rail frame 221 and the mounting pieces 222 are made of extruded shapes formed from a metal material such as aluminum, and extend along the longitudinal direction of the lower frame main body 220.

[0020] The lower frame body 220 is made of wood and has a generally rectangular cross section. The outer surface 220b of the lower frame body 220 is flat along the indoor-outdoor direction, while the inner surface 220a of the lower frame body 220 is stepped, with the indoor side X2 being one step higher. Specifically, as shown in FIG. 7, the inner surface 220a of the lower frame body 220 is formed by an outdoor side inner surface portion 220a1 and an indoor side inner surface portion 220a2 that is one step higher than the outdoor side inner surface portion 220a1. In other words, the vertical thickness of the lower frame body 220 is greater on the indoor side X2 than on the outdoor side X1. The indoor side inner surface portion 220a2 is located closer to the indoor side X2 than the center of the lower frame body 220 in the indoor-outdoor direction. The outdoor side sighting surface 220c and the indoor side sighting surface 220d of the lower frame body 220 are each flat along the vertical direction of the sliding window 1.

[0021] As shown in Figure 7, the rail frame 221 integrally comprises a rail frame main body 2211, an outdoor rail 2212, an indoor rail 2213, and a screen rail 2214 that protrude inward from the rail frame main body 2211, and a hanging piece 2215 that extends outward from the outdoor end X1 of the rail frame main body 2211.

[0022] The rail frame main body 2211 is arranged to cover the inner surface 220a of the lower frame main body 220, following the shape of the stepped inner surface 220a of the lower frame main body 220, and is attached to the inner surface 220a of the lower frame main body 220 with screws (not shown). More specifically, the rail frame main body 2211 is composed of an outdoor rail frame main body portion 2211a that covers the outdoor inner surface portion 220a1, and an indoor rail frame main body portion 2211b that is formed one step higher than the outdoor rail frame main body portion 2211a and covers the indoor inner surface portion 220a2. The outdoor rail frame main body portion 2211a protrudes toward the outdoor side X1 beyond the outdoor viewing surface 220c of the lower frame main body 220, and is inclined downward toward the outdoor side X1.

[0023] An accommodation groove 2201 that accommodates the indoor rail frame main body portion 2211b of the rail frame main body 2211 is formed in the indoor side inner surface portion 220a2 of the lower frame main body 220. The accommodation groove 2201 is formed so as to open toward the outdoor side X1 from a position on the outdoor side X1 that is further away from the extreme end of the indoor side X2 of the indoor side inner surface portion 220a2. The indoor side rail frame main body portion 2211b of the rail frame main body 2211 is accommodated in the accommodation groove 2201. In this state, the indoor side rail frame main body portion 2211b is disposed flush with the indoor side inner surface portion 220a2 and is therefore not noticeable from the indoor side X2.

[0024] The outdoor rail 2212 protrudes inward from an outdoor rail frame main body portion 2211a of the rail frame main body 2211. The outdoor rail 2212 is formed by a pair of rail walls 2212a, 2212a arranged in the indoor / outdoor direction, and a convex rail portion 2212b connecting the upper ends of the pair of rail walls 2212a, 2212a in the indoor / outdoor direction. The indoor rail 2213 protrudes inward from an indoor rail frame main body portion 2211b of the rail frame main body 2211. The indoor rail 2213 is formed by a pair of rail walls 2213a, 2213a arranged in the indoor / outdoor direction, and a convex rail portion 2213b connecting the upper ends of the pair of rail walls 2213a, 2213a in the indoor / outdoor direction. Door rollers 522, 622 of the outer shoji screen 5 and inner shoji screen 6 described below are placed on the rail portions 2212b, 2213b of the outdoor rail 2212 and the indoor rail 2213, respectively. The rail portions 2212b, 2213b are arranged at the same height when viewed along the indoor-outdoor direction.

[0025] The screen door rail 2214 is disposed on the outermost side X1, and protrudes inward from the outer side X1 end of the outer rail frame main body part 2211a of the rail frame main body 2211.

[0026] The hanging piece 2215 extends outward from between the screen door rail 2214 and the outdoor rail 2212 in the outdoor rail frame main body portion 2211a, and abuts against the outdoor sighting surface 220c of the lower frame main body 220 from the outdoor side X1. As shown in Fig. 7, the lower end 2215a of the hanging piece 2215 is positioned inside the position of the outer surface 220b of the lower frame main body 220. The lower end 2215a of the hanging piece 2215 is bent toward the outdoor side X1 so as to move away from the outdoor sighting surface 220c, forming a gap 2215b between it and the outdoor sighting surface 220c.

[0027] The mounting piece 222 is disposed at the end of the lower frame 22 on the indoor side X2. The longitudinal length of the mounting piece 222 is the same as the longitudinal length of the lower frame main body 220. As shown in FIG. 7, the mounting piece 222 is integrally formed with a base plate portion 2221, an L-shaped mounting plate portion 2222 extending from the end of the base plate portion 2221 on the indoor side X2 toward the outside and the indoor side X2, and a bent piece portion 2223 formed by bending the end of the base plate portion 2221 on the outdoor side X1 outward. The mounting plate portion 2222 has a plurality of screw holes 2222a formed along the longitudinal direction.

[0028] A cutout portion 2202 having a rectangular cross section is formed at the end of the outer surface 220b of the lower frame body 220 facing the indoor side X2, spanning from the outer surface 220b to the indoor side facing surface 220d. The cutout portion 2202 extends over the entire length of the lower frame body 220 in the longitudinal direction. The width of the base plate portion 2221 in the indoor-outdoor direction corresponds to the width of the cutout portion 2202 in the indoor-outdoor direction. The protruding height of the mounting plate portion 2222 downward from the base plate portion 2221 is greater than the protruding height of the bent piece portion 2223 extending outward from the base plate portion 2221. The protruding height of the bent piece portion 2223 corresponds to the depth of the cutout portion 2202 extending inward from the outer surface 220b of the lower frame body 220.

[0029] The mounting piece 222 is attached to the lower frame main body 220 by screws 222a that penetrate the base plate portion 2221, with the base plate portion 2221 and the bent piece portion 2223 abutting against the cutout portion 2202. The screws 222a are provided at multiple locations along the length of the mounting piece 222. As a result, the mounting plate portion 2222 of the mounting piece 222 protrudes outward from the outer surface 220b of the lower frame main body 220 and protrudes toward the indoor side X2 from the indoor-side visible surface 220d of the lower frame main body 220. The head of the screw 222a is positioned within the cutout portion 2202 and does not protrude from the outer surface 220b of the lower frame main body 220.

[0030] 8 and 9, the vertical frame 23 on the left side when viewed from the outside side X1 has a vertical frame main body 230, a guide protrusion 231, a screen door guide 232, and an attachment piece 233. The guide protrusion 231, the screen door guide 232, and the attachment piece 233 are each made of an extruded shape formed from a metal material such as aluminum, and extend along the length of the vertical frame main body 230.

[0031] The vertical frame body 230 is made of wood and has a generally rectangular cross section. An inner surface 230a and an outer surface 230b of the vertical frame body 230 are formed flat along the indoor-outdoor direction. An outdoor facing surface 230c and an indoor facing surface 230d of the vertical frame body 230 are each formed flat along the left-right direction of the sliding window 1.

[0032] As shown in FIG. 9, the guide protrusion 231 is composed of a base 2311 and a guide portion 2312 that protrudes from the base 2311 toward the inside of the vertical frame 23. The base 2311 protrudes further in the indoor / outdoor direction than the guide portion 2312. The guide portion 2312 is formed in a hollow shape with a rectangular cross section. As shown in FIG. 9, the inner surface 230a of the vertical frame main body 230 is provided with a pair of mounting grooves 2301, 2302 that extend parallel to each other along the length of the vertical frame main body 230. The guide protrusion 231 is attached to the vertical frame main body 230 with screws (not shown) with the base 2311 accommodated in the mounting groove 2301 on the outdoor side X1. As a result, the guide protrusion 231 protrudes inward from the inner surface 230a of the vertical frame main body 230 and forms an engagement portion with the door edge frame 53 of the outer shoji screen 5 (described later).

[0033] The screen door guide 232 is positioned on the outermost side X1 and, as shown in Figure 9, is composed of an L-shaped guide piece 2321 that extends toward the inside of the vertical frame 23 and toward the indoor side X2, and an overhanging piece 2322 that overhangs outward from the guide piece 2321. The screen door guide 232 is attached to the outdoor-facing surface 230c of the vertical frame main body 230 with a screw 232a that passes through the overhanging piece 2322, with the overhanging piece 2322 abutting against the outdoor-facing surface 230c of the vertical frame main body 230. The guide piece 2321 protrudes inward beyond the inner surface 230a of the vertical frame main body 230.

[0034] The mounting piece 233 is disposed at the end of the vertical frame 23 on the indoor side X2. The length of the mounting piece 233 in the longitudinal direction is the same as the length of the vertical frame main body 230 in the longitudinal direction. As shown in Fig. 9, the mounting piece 233 is integrally formed with a base plate portion 2331, an L-shaped mounting plate portion 2332 extending from the end of the base plate portion 2331 on the indoor side X2 toward the outside and the indoor side X2, and a bent piece portion 2333 formed by bending the end of the base plate portion 2331 on the outdoor side X1 outward. A plurality of screw holes 2332a are formed in the mounting plate portion 2332 along the longitudinal direction.

[0035] A cutout portion 2303 having a rectangular cross section is formed at the end of the outer surface 230b of the vertical frame main body 230 on the indoor side X2, spanning from the outer surface 230b to the indoor side facing surface 230d. The cutout portion 2303 extends the entire length of the vertical frame main body 230. The width of the base plate portion 2331 in the indoor-outdoor direction corresponds to the width of the cutout portion 2303 in the indoor-outdoor direction. The height by which the mounting plate portion 2332 protrudes outward from the base plate portion 2331 is the same as the height by which the bent piece portion 2333 protrudes outward from the base plate portion 2331. The height by which the mounting plate portion 2332 and the bent piece portion 2333 protrude from the base plate portion 2331 corresponds to the depth of the cutout portion 2303 inward from the outer surface 230b of the vertical frame main body 230.

[0036] The mounting piece 233 is attached to the vertical frame main body 230 by screws 233a that penetrate the base plate portion 2331, with the base plate portion 2331 and the bent piece portion 2333 abutting against the cutout portion 2303. The screws 233a are provided at multiple locations along the length of the mounting piece 233. As a result, the mounting plate portion 2332 of the mounting piece 233 protrudes outward from the outer surface 230b of the vertical frame main body 230, and protrudes toward the room side X2 from the room-side visible surface 230d of the vertical frame main body 230. The head of the screw 233a is positioned within the cutout portion 2303 and does not protrude from the outer surface 230b of the vertical frame main body 230.

[0037] 10 and 11, when viewed from the outside side X1, the right-side vertical frame 24 is symmetrical to the left-side vertical frame 23, and has a vertical frame main body 240, a guide protrusion 241, a screen door guide 242, and an attachment piece 243. The guide protrusion 241, the screen door guide 242, and the attachment piece 243 are each made of an extruded shape formed from a metal material such as aluminum, and extend along the length of the vertical frame main body 240.

[0038] The vertical frame body 240 is made of wood and has a generally rectangular cross section. An inner surface 240a and an outer surface 240b of the vertical frame body 240 are formed flat along the indoor-outdoor direction. An outdoor-facing surface 240c and an indoor-facing surface 240d of the vertical frame body 240 are each formed flat along the left-right direction of the sliding window 1.

[0039] As shown in FIG. 11 , the guide protrusion 241 includes a base 2411 and a guide portion 2412 that protrudes from the base 2411 toward the inside of the vertical frame 24. The base 2411 protrudes further in the indoor / outdoor direction than the guide portion 2412. The guide portion 2412 is formed into a hollow shape with a rectangular cross section. As shown in FIG. 11 , a pair of mounting grooves 2401, 2402 that extend parallel to each other along the length of the vertical frame main body 240 are provided on the inner surface 240a of the vertical frame main body 240. The guide protrusion 241 is attached to the vertical frame main body 240 with screws (not shown) with the base 2411 accommodated in the mounting groove 2402 on the indoor side X2. As a result, the guide protrusion 241 protrudes inward from the inner surface 240a of the vertical frame main body 240 and forms an engagement portion with the door edge frame 63 of the inner shoji screen 6 (described later).

[0040] The screen door guide 242 is positioned on the outermost side X1 and, as shown in Figure 11, is composed of an L-shaped guide piece 2421 that extends toward the inside of the vertical frame 24 and toward the indoor side X2, and an overhanging piece 2422 that overhangs outward from the guide piece 2421. The screen door guide 242 is attached to the outdoor-facing surface 240c of the vertical frame main body 240 with a screw 242a that passes through the overhanging piece 2422, with the overhanging piece 2422 abutting against the outdoor-facing surface 240c of the vertical frame main body 240. The guide piece 2421 protrudes inward beyond the inner surface 240a of the vertical frame main body 240.

[0041] The mounting piece 243 is disposed at the end of the vertical frame 24 on the indoor side X2. The length of the mounting piece 243 in the longitudinal direction is the same as the length of the vertical frame main body 240 in the longitudinal direction. As shown in FIG. 11 , the mounting piece 243 is integrally formed with a base plate portion 2431, an L-shaped mounting plate portion 2432 extending from the end of the base plate portion 2431 on the indoor side X2 toward the outside and the indoor side X2, and a bent piece portion 2433 formed by bending the end of the base plate portion 2431 on the outdoor side X1 outward. A plurality of screw holes 2432a are formed in the mounting plate portion 2432 along the longitudinal direction.

[0042] A cutout portion 2403 having a rectangular cross section is formed at the end of the outer surface 240b of the vertical frame main body 240 on the indoor side X2, spanning from the outer surface 240b to the indoor side visible surface 240d. The cutout portion 2403 extends the entire length of the vertical frame main body 240. The width of the base plate portion 2431 in the indoor-outdoor direction corresponds to the width of the cutout portion 2403 in the indoor-outdoor direction. The protruding height of the mounting plate portion 2432 extending outward from the base plate portion 2431 is the same as the protruding height of the bent piece portion 2433 extending outward from the base plate portion 2431. The protruding height of the mounting plate portion 2432 and the bent piece portion 2433 from the base plate portion 2431 corresponds to the depth of the cutout portion 2403 extending inward from the outer surface 240b of the vertical frame main body 240.

[0043] The mounting piece 243 is attached to the vertical frame main body 240 by screws 243a that penetrate the base plate portion 2431, with the base plate portion 2431 and the bent piece portion 2433 abutting against the cutout portion 2403. The screws 243a are provided at multiple locations along the length of the mounting piece 243. As a result, the mounting plate portion 2432 of the mounting piece 243 protrudes outward from the outer surface 240b of the vertical frame main body 240, and protrudes toward the indoor side X2 from the indoor-side visible surface 240d of the vertical frame main body 240. The head of the screw 243a is positioned within the cutout portion 2403 and does not protrude from the outer surface 240b of the vertical frame main body 240.

[0044] In this embodiment, the upper frame body 210 and the vertical frame bodies 230, 240 have a common structure. That is, the upper frame body 210 and the vertical frame bodies 230, 240 use a common wooden frame body for the upper frame side and the left and right vertical frame sides, respectively. Because the frame bodies of the upper frame 21 and the left and right vertical frames 23, 24 can be manufactured in common, manufacturing costs are reduced and parts management is simplified.

[0045] Next, the attachment 3 will be described. The attachment 3 is constructed by assembling an upper attachment member 31, a lower attachment member 32, and a pair of left and right vertical attachment members 33, 34 in a rectangular shape so that they fit the opening shape of the opening 101. The attachment 3 has a vertically aligned structure in which the upper attachment member 31 and the lower attachment member 32 are arranged inside the left and right vertical attachment members 33, 34. The upper attachment member 31, the lower attachment member 32, and the pair of left and right vertical attachment members 33, 34 are each made of extruded shapes formed from a metal material such as aluminum.

[0046] The upper attachment member 31 and the lower attachment member 32 have the same structure and are arranged symmetrically in the vertical direction. Therefore, the upper attachment member 31 and the lower attachment member 32 will be described together with reference to FIG.

[0047] The upper attachment member 31 and the lower attachment member 32 are integrally formed by having main body plate portions 310, 320, body mounting pieces 311, 321, outdoor abutment pieces 312, 322, indoor mounting portions 313, 323, multiple protrusions 314, 324, and multiple tapping holes 315, 325.

[0048] The main body plate portions 310, 320 are formed in a flat plate shape. The width of the main body plate portions 310, 320 in the indoor / outdoor direction corresponds to the width of the upper frame 21 and the lower frame 22 including the mounting pieces 214, 222 in the indoor / outdoor direction.

[0049] The frame mounting pieces 311, 321 extend outward from positions closer to the outdoor side X1 than the center of the main body plate portions 310, 320 in the indoor / outdoor direction, and form mounting portions to the building frame 100.

[0050] The outdoor abutment pieces 312, 322 are portions that abut against the outdoor facing surfaces 210c, 220c of the upper frame body 210 and the lower frame body 220 from the outdoor side X1, and have a shape in which the outdoor side X1 ends of the main body plate portions 310, 320 are bent inward. Waterproof sealants 312a, 322a made of an elastic material such as rubber are provided on the indoor side X2 surfaces of the outdoor abutment pieces 312, 322.

[0051] The indoor side mounting portions 313, 323 are arranged at the ends of the main body plate portions 310, 320 on the indoor side X2, and extend toward the indoor side X2 flush with the main body plate portions 310, 320. The indoor side mounting portions 313, 323 are arranged so as to overlap the mounting plate portions 2142, 2222 of the mounting pieces 214, 222 of the upper frame 21 and the lower frame 22 from the outside of the upper frame 21 and the lower frame 22.

[0052] The multiple protrusions 314, 324 are formed to protrude at the same height from the outer surface of the main body plate portion 310, 320, which is the same surface as the surface on which the body mounting pieces 311, 321 are arranged. The multiple protrusions 314, 324 are lower in protrusion height than the body mounting pieces 311, 321 and are arranged closer to the indoor side X2 than the body mounting pieces 311, 321, with intervals in the indoor / outdoor direction. In this embodiment, four protrusions 314, 324 are provided on the upper attachment member 31 and the lower attachment member 32. Two of the four protrusions 314, 324 are arranged adjacent to the outdoor side X1 and the indoor side X2 of the indoor mounting portion 313, 323. In other words, the indoor mounting portion 313, 323 is formed between the two protrusions 314, 324.

[0053] The tapping holes 315, 325 are locations where screws are driven in to secure the upper or lower ends of the left and right vertical attachment members 33, 34. The tapping holes 315, 325 protrude from the inner surface of the main body plate portions 310, 320, which is the surface opposite to the surface on which the frame mounting pieces 311, 321 are arranged, and are arranged at intervals in the indoor / outdoor direction.

[0054] The left and right vertical attachment members 33, 34 have the same structure and are arranged symmetrically, so the left and right vertical attachment members 33, 34 will be described together with reference to FIG.

[0055] The vertical attachment members 33, 34 are integrally formed by having main body plate portions 330, 340, body mounting pieces 331, 341, outdoor abutment pieces 332, 342, indoor mounting portions 333, 343, a plurality of protruding pieces 334, 334, and folded pieces 335, 345.

[0056] The main body plate portions 330, 340 are formed in a flat plate shape. The width of the main body plate portions 330, 330 in the indoor / outdoor direction corresponds to the width of the vertical frames 23, 24 including the mounting pieces 233, 243 in the indoor / outdoor direction.

[0057] The frame mounting pieces 331, 341 extend outward from a position closer to the outdoor side X1 than the center of the main body plate portions 330, 340 in the indoor / outdoor direction, and form a mounting portion to the building frame 100.

[0058] The outdoor abutment pieces 332, 342 are portions that abut against the outdoor facing surfaces 230c, 240c of the vertical frame bodies 230, 240 from the outdoor side X1, and have a shape in which the outdoor side X1 end of the body plate parts 330, 340 is bent inward. Waterproof sealants 332a, 342a made of an elastic material are provided on the indoor side X2 surface of the outdoor abutment pieces 332, 342.

[0059] The indoor side mounting portions 333, 343 are arranged at the ends of the main body plate portions 330, 340 on the indoor side X2, and extend toward the indoor side X2 flush with the main body plate portions 330, 340. The indoor side mounting portions 333, 343 are arranged so as to overlap the mounting plate portions 2332, 2432 of the mounting pieces 233, 243 of the left and right vertical frames 23, 24 from the outside of the left and right vertical frames 23, 24.

[0060] The multiple protrusions 334, 344 are formed to protrude at the same height from the outer surface of the main body plate portion 330, 340, which is the same surface as the surface on which the body mounting pieces 331, 341 are arranged. The multiple protrusions 334, 344 protrude lower than the body mounting pieces 331, 341 and are arranged closer to the indoor side X2 than the body mounting pieces 331, 341, with intervals in the indoor / outdoor direction. In this embodiment, the vertical attachment member 33, 34 is provided with three protrusions 334, 344. Two of the three protrusions 334, 344 are arranged adjacent to the outdoor side X1 and the indoor side X2 of the indoor mounting portion 333, 343. In other words, the indoor mounting portion 333, 343 is formed between the two protrusions 334, 344.

[0061] The folded pieces 335, 345 are arranged at the ends of the body plate portions 330, 340 on the outdoor side X1, and have a shape that is bent outward and toward the indoor side X2.

[0062] Next, a method for attaching the wooden frame 2 will be described with reference to Figures 14 to 16. The wooden frame 2 is attached to the inside of the attachments 3 that have already been attached around the four sides of the opening 101 of the building skeleton 100. The attachment 3 is attached and fixed to the inside of the opening 101 of the building skeleton 100 in a state in which the upper attachment member 31, the lower attachment member 32, and the pair of left and right vertical attachment members 33, 34 are assembled in advance into a rectangular shape.

[0063] 14, the multiple protrusions 314 of the upper attachment member 31 abut against the inner surface 101a of the opening 101, and the frame mounting piece 311 abuts against the exterior side surface 100a of the building frame 100 from the outside side X1. In this state, the upper attachment member 31 is fixed to the building frame 100 by screws 311a that pass through the frame mounting piece 311 from the outside side X1. A waterproof sheet 111 is attached from the outside side X1 to the frame mounting piece 311 into which the screws 311a have been driven, so as to cover the heads of the screws 311a.

[0064] 15, the multiple protrusions 324 of the lower attachment member 32 abut against the lower inner surface 101b of the opening 101, and the frame mounting piece 321 abuts against the exterior side surface 100a of the building frame 100 from the outside side X1. In this state, the lower attachment member 32 is fixed to the building frame 100 by screws 321a that pass through the frame mounting piece 321 from the outside side X1. A waterproof sheet 111 is attached from the outside side X1 to the frame mounting piece 321 into which the screws 321a have been driven, so as to cover the heads of the screws 321a.

[0065] 16 and 17, the multiple protrusions 334, 344 of the left and right vertical attachment members 33, 34 abut against the inner surfaces 101c, 101d on the left and right vertical sides of the opening 101, and the frame mounting pieces 331, 341 abut against the exterior side surface 100a of the building frame 100 from the outside side X1. In this state, the vertical attachment members 33, 34 are fixed to the building frame 100 by screws 331a, 341a that penetrate the frame mounting pieces 331, 341 from the outside side X1. A waterproof sheet 111 is attached from the outside side X1 to the frame mounting pieces 331, 341 into which the screws 331a, 341a have been driven, so as to cover the heads of the screws 331a, 341a.

[0066] Next, the wooden frame 2, which is a rectangular frame made up of the upper frame 21, lower frame 22, and pair of left and right vertical frames 23, 24, is fitted and fixed from the indoor side X2 to the inside of the attachment 3, which is attached to the opening 101 of the building skeleton 100 all around. The wooden frame 2 is fixed at its end on the indoor side X2 to the end on the indoor side X2 of the attachment 3 with screws.

[0067] 14, the upper frame 21 attached to the inside of the attachment 3 abuts against the upper attachment member 31 from its inside. The outer surface 210b of the upper frame body 210 abuts against and is supported by a plurality of tapping holes 315 of the upper attachment member 31. The outdoor-facing surface 210c of the upper frame body 210 abuts against and is supported by the outdoor-side abutment piece 312 of the upper attachment member 31 from the indoor side X2. The gap between the outdoor abutment piece 312 and the upper frame body 210 is sealed by a sealant 312a.

[0068] The mounting plate portions 2142 of the mounting pieces 214 provided on the upper frame 21 protrude outward from the outer surface 210b of the upper frame main body 210 by a height corresponding to the protruding height of the multiple tapping holes 315. The mounting plate portions 2142 abut against the indoor-side mounting portions 313 of the upper attachment member 31 so as to overlap from the inside. In this state, screws 21a are driven into the screw holes 2142a of the mounting plate portions 2142 from the inside of the wooden frame 2. The screws 21a penetrate the mounting plate portions 2142 and the indoor-side mounting portions 313 and are driven into the building skeleton 100. As a result, the indoor-side mounting portions 313 of the upper attachment member 31 and the mounting pieces 214 of the upper frame 21 are fastened together to the building skeleton 100 by the screws 21a, and the upper frame 21 of the wooden frame 2 is attached to the building skeleton 100 via the upper attachment member 31. The head of the screw 214a that fixes the mounting piece 214 to the upper frame body 210 is accommodated within the cutout portion 2103 of the upper frame body 210 and does not protrude beyond the outer surface 210b of the upper frame body 210, so it does not interfere with the upper attachment member 31 when attached to the upper attachment member 31.

[0069] As shown in Figure 15, the lower frame 22 attached to the inside of the attachment 3 abuts against the lower attachment member 32 from its inside. The outer surface 220b of the lower frame main body 220 abuts against and is supported by a plurality of tapping holes 325 of the lower attachment member 32. The outdoor-facing surface 220c of the lower frame main body 220 abuts against and is supported by the outdoor-side abutment piece 322 of the lower attachment member 32 from the indoor side X2. The gap between the outdoor abutment piece 322 and the lower frame main body 220 is sealed by a sealant 322a.

[0070] The mounting plate portions 2222 of the mounting pieces 222 provided on the lower frame 22 protrude outward from the outer surface 220b of the lower frame main body 220 by a height corresponding to the protruding height of the multiple tapping holes 325. The mounting plate portions 2222 abut against the indoor-side mounting portions 323 of the lower attachment member 32 so as to overlap the interior side mounting portions 323 from the inside. In this state, screws 22a are driven into the screw holes 2222a of the mounting plate portions 2222 from the inside of the wooden frame 2. The screws 22a penetrate the mounting plate portions 2222 and the indoor-side mounting portions 323 and are driven into the building skeleton 100. As a result, the indoor-side mounting portions 323 of the lower attachment member 32 and the mounting pieces 222 of the lower frame 22 are fastened together to the building skeleton 100 by the screws 22a, and the lower frame 22 of the wooden frame 2 is attached to the building skeleton 100 via the lower attachment member 32. The head of the screw 222a that fixes the mounting piece 222 to the lower frame body 220 is accommodated within the cutout portion 2202 of the lower frame body 220 and does not protrude beyond the outer surface 220b of the lower frame body 220, so it does not interfere with the lower attachment member 32 when attached to the lower attachment member 32.

[0071] As shown in Figures 16 and 17, the left and right vertical frames 23, 24 attached to the inside of the attachment 3 abut against the left and right vertical attachment members 33, 34 from their insides. The outer surfaces 230b, 240b of the vertical frame bodies 230, 240 abut against and are supported by the body plate portions 330, 340 of the vertical attachment members 33, 34. The outdoor-facing surfaces 230c, 240c of the vertical frame bodies 230, 240 abut against and are supported by the outdoor-side abutment pieces 332, 342 of the vertical attachment members 33, 34 from the indoor side X2. The gap between the outdoor abutment pieces 332, 342 and the vertical frame bodies 230, 240 is sealed by sealants 332a, 342a.

[0072] The mounting plate portions 2332, 2432 of the mounting pieces 233, 243 provided on the vertical frames 23, 24 are arranged flush with the outer surfaces 220b of the vertical frame bodies 230, 240. The mounting plate portions 2332, 2432 abut against the indoor-side mounting portions 333, 343 of the vertical attachment members 33, 34 so as to overlap from the inside. In this state, screws 23a, 24a are driven into the screw holes 2332a, 2432a of the mounting plate portions 2332, 2432 from the inside of the wooden frame 2. The screws 23a, 24a pass through the mounting plate portions 2332, 2432 and the indoor-side mounting portions 333, 343, and are driven into the building skeleton 100. As a result, the indoor mounting portions 333, 343 of the vertical attachment members 33, 34 and the mounting pieces 233, 243 of the vertical frames 23, 24 are fastened together to the building skeleton 100 by the screws 23a, 24a, and the vertical frames 23, 24 of the wooden frame 2 are attached to the building skeleton 100 via the vertical attachment members 33, 34. The heads of the screws 233a, 243a that secure the mounting pieces 233, 243 to the vertical frame main bodies 230, 240 are housed in the cutout portions 2303, 2403 of the vertical frame main bodies 230, 240 and do not protrude outward beyond the outer surfaces 230b, 240b of the vertical frame main bodies 230, 240, so they do not interfere with the vertical attachment members 33, 34 when attached to the vertical attachment members 33, 34.

[0073] As a result of the above, the wooden frame 2 is placed around the inside of the attachment 3 that has been attached around the opening 101 of the building skeleton 100, and the wooden frame 2 and the attachment 3 are fastened together and fixed to the building skeleton 100 with screws 21a, 22a, 23a, and 24a. After the attachment 3 has been attached to the building skeleton 100, an exterior wall material 110 is installed on the exterior side X1 of the building skeleton 100. As shown in FIGS. 14 to 17, a sealant 112 is filled in the gap between the exterior wall material 110 and the attachment 3. A backup material 113 is placed between the sealant 112 and the exterior side surface 100a of the building skeleton 100. Furthermore, after the wooden frame 2 is attached inside the attachment 3, an interior wall material 120 is installed on the interior side X2 of the building skeleton 100.

[0074] After the wooden frame 2 is attached, the frame members 4 are attached around the four periphery of the indoor side X2 of the wooden frame 2. The frame members 4 are composed of an upper frame member 41, a lower frame member 42, and a pair of left and right vertical frame members 43, 44, each of which has a rectangular cross section. Cutouts 411, 421, 431, 441 are formed in the ends of the outer surfaces 41a, 42a, 43a, 44a of the upper frame member 41, the lower frame member 42, and the pair of left and right vertical frame members 43, 44, facing the outdoor side X1.

[0075] As shown in Fig. 4, the upper frame member 41 abuts against the indoor-side visible surface 210d of the upper frame body 210 from the indoor side X2. The cutout portion 411 of the upper frame member 41 covers and conceals the mounting plate portion 2142 of the mounting piece 214 of the upper frame 21 and the head of the screw 21a from the inside. The inner surface 41b of the upper frame member 41 is disposed flush with the inner surface 210a of the upper frame body 210.

[0076] 6, the lower frame member 42 abuts against the indoor-side visible surface 220d of the lower frame body 220 from the indoor side X2. The cutout portion 421 of the lower frame member 42 covers the mounting plate portion 2222 of the mounting piece 222 of the lower frame 22 and the head of the screw 22a from the inside. The inner surface 42b of the lower frame member 42 is positioned at the same height as the outdoor-side inner surface portion 220a1 of the lower frame body 220.

[0077] As shown in Figures 8 and 10, the left and right vertical frame members 43, 44 abut against the room-side facing surfaces 230d, 240d of the vertical frame bodies 230, 240 from the room side X2. The cutout portions 431, 441 of the vertical frame members 43, 44 accommodate the mounting plate portions 2332, 2432 of the mounting pieces 233, 243 of the vertical frames 23, 24 and the heads of the screws 23a, 24a, concealing them from the inside. The inner surfaces 43b, 44b of the vertical frame members 43, 44 are arranged flush with the inner surfaces 230a, 240a of the vertical frame bodies 230, 240.

[0078] In the wooden frame 2 attached to the building skeleton 100 in this manner, the screws 21a, 22a, 23a, and 24a are not exposed on the inner surfaces 210a, 220a, 230a, and 240a of the wooden frame 2. This gives the wooden frame 2 a good appearance and excellent design. The wooden frame 2 is fixed to the attachment 3 at the end of the interior side X2 by the screws 21a, 22a, 23a, and 24a. Therefore, after removing the frame member 4, the screws 21a, 22a, 23a, and 24a are easily accessible from the inside of the wooden frame 2. Furthermore, the wooden frame 2 can be easily removed from the attachment 3 while the attachment 3 remains attached to the building skeleton 100, without having to demolish the exterior wall material 110 and the interior wall material 120. After replacing the wooden frame 2, there is no need to reapply the exterior wall material 110, the interior wall material 120, and the sealing material 112.

[0079] Next, we will explain the outer shoji screen 5 and the inner shoji screen 6 that are housed inside the wooden frame body 2. Since the outer shoji screen 5 and the inner shoji screen 6 have a symmetrical structure, the outer shoji screen 5 and the inner shoji screen 6 will be explained together below.

[0080] As shown in Figures 4, 6, 8, 10, and 18, the outer shoji screen 5 and the inner shoji screen 6 are each constructed by fitting a panel G inside a rectangular wooden frame 50, 60. In this embodiment, the panel G is constructed of triple glazing, consisting of three glass panes G1 stacked with spacers G2 between them. However, the panel G of the outer shoji screen 5 and the inner shoji screen 6 is not limited to triple glazing, and may be constructed of, for example, double glazing, consisting of two or more glass panes G1 stacked with spacers G2 between them. The outer shoji screen 5 is fitted between the exterior rail 211 of the upper frame 21 and the exterior rail 2212 of the lower frame 22 so as to be slidable laterally. The inner shoji screen 6 is fitted between the interior rail 212 of the upper frame 21 and the interior rail 2213 of the lower frame 22 so as to be slidable laterally.

[0081] The wooden frames 50, 60 are formed by assembling upper frames 51, 61, lower frames 52, 62, end frames 53, 63, and joint frames 54, 64 into a rectangular shape. The wooden frames 50, 60 have a vertically aligned structure in which the upper frames 51, 61 and lower frames 52, 62 are attached to the inside of the left and right end frames 53, 63 and joint frames 54, 64. There are no particular restrictions on the type of wood used for the wooden frames 50, 60, but generally the same type of wood as that used for the wooden frame 2 is used to create a sense of design unity with the wooden frame 2.

[0082] As shown in Figure 4, the upper frames 51, 61 have rail grooves 511, 611 formed on the upper end faces 51a, 61a thereof that engage with the outdoor rail 211 and the indoor rail 212 of the upper frame 21, over the entire length of the upper frames 51, 61. A pair of fin members 512, 612 are provided on each of the upper end faces 51a, 61a, sandwiching the rail grooves 511, 611. The fin members 512, 612 abut against the outdoor rail 211 and the indoor rail 212 that engage with the rail grooves 511, 611 from the outdoor side X1 and the indoor side X2. This blocks ventilation from the indoor / outdoor direction on the upper frame 21 side of the outer shoji screen 5 and the inner shoji screen 6, ensuring airtightness.

[0083] A storage section 513, 613 for storing the panel G is formed on the lower end surface 51b, 61b of the upper frame 51, 61. The storage section 513, 613 is formed by cutting out the lower end surface 51b, 61b in a stepped shape from the outdoor side X1 toward the indoor side X2. The upper end of the panel G is stored in the storage section 513, 613 via a buffer material 514, 614 arranged at the bottom of the storage section 513, 613. An edge member 515, 615 that supports the panel G from the indoor side X2 is attached to the indoor side X2 of the upper end of the panel G stored in the storage section 513, 613 with screws 515a, 615a. The spacer G2 at the upper end of the panel G is entirely stored in the storage section 513, 613 and hidden by the upper frame 51, 61, so it is difficult to see from the outdoor side X1 and the indoor side X2.

[0084] As shown in Fig. 6, rail grooves 521, 621 that engage with the outdoor rail 2212 and the indoor rail 2213 of the lower frame 22 are formed on the lower end surfaces 52a, 62a of the lower frames 52, 62 over the entire length of the lower frames 52, 62. Door rollers 522, 622 that roll on the rail portions 2212b, 2213b of the outdoor rail 2212 and the indoor rail 2213 are provided inside the rail grooves 521, 621. A pair of fin members 523, 623 are provided on the lower end surfaces 52a, 62a, respectively, to sandwich the rail grooves 521, 621. The fin members 523, 623 abut against the outdoor rail 2212 and the indoor rail 2213 that engage with the rail grooves 521, 621 from the outdoor side X1 and the indoor side X2. This blocks ventilation from the inside to the outside on the lower frame 22 side of the outer shoji screen 5 and inner shoji screen 6, ensuring airtightness.

[0085] The upper end surfaces 52b, 62b of the lower frames 52, 62 are formed with storage sections 524, 624 for storing the panel material G. The storage sections 524, 624 are formed by cutting out the upper end surfaces 52b, 62b in a stepped pattern from the exterior side X1 toward the interior side X2. The lower end of the panel material G is stored in the storage section 524, 624 via a cushioning material 525, 625 arranged at the bottom of the storage section 524, 624. Edge members 526, 626 that support the panel material G from the interior side X2 are attached with screws 526a, 626a to the interior side X2 of the lower end of the panel material G stored in the storage section 524, 624. The spacer G2 at the lower end of the panel material G is entirely stored in the storage section 524, 624 and hidden by the lower frames 52, 62, and is therefore difficult to see from the exterior side X1 and the interior side X2.

[0086] As shown in Figures 8 and 10, the door end stiles 53, 63 have grooves 531, 631 formed on the outer end surfaces 53a, 63a facing the vertical frames 23, 24, which engage with the guide protrusions 231, 241 of the vertical frames 23, 24, over the entire length of the door end stiles 53, 63. Inside the grooves 531, 631, anti-vibration components 532, 632 are attached over the entire length of the door end stiles 53, 63. The anti-vibration components 532, 632 are each composed of a gutter-shaped resin base portion 532a, 632a and an adjustment block 532b, 631b. The anti-sway components 532, 632 are attached to the grooves 531, 631 with screws (not shown) with the bases 532a, 632a positioned deep within the grooves 531, 631 and the adjustment blocks 532b, 631b positioned so as to overlap the door edge side of the bases 532a, 632a. When the outer shoji screen 5 and inner shoji screen 6 are closed, the anti-sway components 532, 632 fit the guide protrusions 231, 241 of the vertical frames 23, 24 into the inside of the adjustment blocks 532b, 631b, thereby preventing the outer shoji screen 5 and inner shoji screen 6 from vibrating in the indoor / outdoor directions.

[0087] A pair of fin members 533, 633 are provided on the outer end surfaces 53a, 63a of the door end frames 53, 63, respectively, sandwiching the grooves 531, 631. The fin members 533, 633 abut against the guide protrusions 231, 241 that engage with the anti-vibration parts 532, 632 in the grooves 531, 631 from the outside X1 and inside X2. This blocks ventilation from the inside to outside of the room on the vertical frames 23, 24 side of the outer shoji screen 5 and inner shoji screen 6, ensuring airtightness.

[0088] Storage sections 534, 634 that store the panel material G are formed on the inner end surfaces 53b, 63b of the door end frames 53, 63. The storage sections 534, 634 are formed by cutting out the inner end surfaces 53b, 63b in a stepped pattern from the outside side X1 to the inside side X2. The door end side end of the panel material G is stored in the storage section 534, 634 via cushioning materials 535, 635 arranged at the bottom of the storage section 534, 634. Edge members 536, 636 that support the panel material G from the inside side X2 are attached with screws 536a, 636a to the inside side X2 of the door end side end of the panel material G stored in the storage section 534, 634. The entire spacer G2 at the end of the panel G on the door tip side is housed within the housing portion 534, 634 and is hidden by the door tip frames 53, 63, so it is difficult to see from the outside X1 and inside X2 of the room.

[0089] Operating handles 530, 630 are attached to the interior facing surfaces 53d, 63d of the door end frames 53, 63, respectively.

[0090] As shown in Figure 18, the door frame 54, 64 are arranged so that they overlap in the indoor-outdoor direction when the outer door 5 and the inner door 6 are closed. The interior facing surface 54a of the door frame 54 and the exterior facing surface 64a of the door frame 64 are each formed in a stepped shape. The respective stepped interior facing surfaces 54a and exterior facing surfaces 64a are arranged complementarily to each other when the outer door 5 and the inner door 6 are closed. In other words, the interior facing surface 54a of the door frame 54 protrudes in a stepped manner toward the interior side X2 as it moves toward the outside of the wooden frame 50, and the exterior facing surface 64a of the door frame 64 protrudes in a stepped manner toward the exterior side X1 as it moves toward the outside of the wooden frame 50. The indoor side sighting surface 54a and the outdoor side sighting surface 64a are provided with fin members 541, 641 made of an elastic material such as rubber. When the outer screen 5 and the inner screen 6 are closed, the fin members 541, 641 abut against the opposing outdoor side sighting surface 64a and indoor side sighting surface 54a, blocking ventilation between the mating frames 54, 64 in the indoor and outdoor directions and ensuring airtightness.

[0091] Storage sections 542, 642 that store the panel G are formed on the inner end surfaces 54b, 64b of the panel frames 54, 64. The storage sections 542, 642 are formed by cutting out the inner end surfaces 54b, 64b in a stepped pattern from the outside side X1 toward the inside side X2. The end of the panel G on the side of the panel frame 54, 64 is stored in the storage section 542, 642 via cushioning materials 543, 643 that are placed at the bottom of the storage section 542, 642. Edge members 544, 644 that support the panel G from the inside side X2 are attached with screws 544a, 644a to the inside side X2 of the end of the panel G on the side of the panel frame 54, 64 of the panel G stored in the storage section 542, 642. The entire spacer G2 at the end of the panel G on the side of the joining frames 54, 64 is housed within the housing portion 542, 642 and is hidden by the joining frames 54, 64, so it is difficult to see from the outside X1 and the inside X2 of the room.

[0092] In the wooden frames 50, 60 of the outer and inner shoji screens 5, 6 of this embodiment, the upper frame 51 and the left and right door edge frames 53, 63 have the same structure except for their different lengths. This reduces the number of parts, thereby reducing the cost of the sliding window 1.

[0093] The screen door 7 is formed by stretching a mesh body 74 across the inside of a frame body 70, which is made up of an upper frame 71, a lower frame 72, and a pair of left and right vertical frames 73 assembled into a rectangle. The screen door 7 is housed between the screen door rail 213 of the upper frame 21 and the screen door rail 2214 of the lower frame 22 so that it can slide left and right.

[0094] 19 to 21 show a fixture according to the second embodiment. This fixture is a fixed window 1A that is attached to an opening 101 in a building skeleton 100. Parts with the same reference numerals as those in the sliding window 1 according to the first embodiment indicate parts with the same configuration, and therefore the detailed description of those parts will be omitted below, with the above description being used as an example.

[0095] The fixed window 1A is constructed by attaching a shoji screen 5A, which has a face material G housed directly inside a rectangular wooden frame 50A, to the inside of an attachment 3 so that it cannot be opened or closed. The upper frame 51A, lower frame 52A, and left and right vertical frames 53A, 54A of the wooden frame 50A correspond to the upper frame 21, lower frame 22, and left and right vertical frames 23, 24, respectively, of the wooden frame 2 of the sliding window 1. Therefore, mounting pieces 214, 222, 233, 243 are attached to the interior side X2 ends of the upper frame 51A, lower frame 52A, and left and right vertical frames 53A, 54A using the same mounting structure as the sliding window 1.

[0096] The upper frame 51A, lower frame 52A, and left and right vertical frames 53A, 54A are fastened together with the attachment 3 to the building skeleton 100 from the inside with screws 21a, 22a, 23a, 24a that pass through the mounting plate portions 2142, 2222, 2332, 2432 of the mounting pieces 214, 222, 233, 243 and the indoor mounting portions 313, 323, 333, 343 of the attachment 3, just like the wooden frame 2 of the sliding window 1. This fixed window 1A also provides the same effects as the sliding window 1.

[0097] 22 to 24 show a fixture according to the third embodiment. This fixture is a casement window 1B that is attached to an opening 101 in a building skeleton 100. Since parts with the same reference numerals as those in the sliding window 1 according to the first embodiment have the same configuration, the above description will be used to refer to them and detailed descriptions thereof will be omitted below.

[0098] The casement window 1B is constructed by fitting a shoji screen 5B inside a rectangular wooden frame 2B so that it can be opened and closed. The upper frame 21B, lower frame 22B, and left and right vertical frames 23B, 24B of the wooden frame 2B correspond to the upper frame 21, lower frame 22, and left and right vertical frames 23, 24, respectively, of the wooden frame 2 of the sliding window 1. Therefore, mounting pieces 214, 222, 233, 243 are attached to the ends of the upper frame 21B, lower frame 22B, and left and right vertical frames 23B, 24B on the interior side X2, respectively, using the same mounting structure as the sliding window 1.

[0099] The upper frame 21B, lower frame 22B, and left and right vertical frames 23B, 24B are fastened together with the attachment 3 to the building structure 100 from the inside using screws 21a, 22a, 23a, 24a that pass through the mounting plate portions 2142, 2222, 2332, 2432 of the mounting pieces 214, 222, 233, 243 and the indoor mounting portions 313, 323, 333, 343 of the attachment 3, in the same way as the wooden frame body 2 of the sliding window 1.

[0100] The shoji screen 5B is constructed by fitting a panel G inside a wooden frame 50B, which is made up of an upper frame 51B, a lower frame 52B, and left and right vertical frames 53B and 54B joined together in a rectangular shape. An operating handle 540B for opening and closing the shoji screen 5B is attached to the interior surface of one of the vertical frames 54B. This casement window 1B also provides the same effects as the sliding window 1.

[0101] Figures 25 to 31 show a fitting according to the fourth embodiment. This fitting is a sliding window 1C that is attached to an opening 101 in a building skeleton 100. The configuration of the sliding window 1C is the same as that of the sliding window 1 according to the first embodiment, except for the wooden frames 50C, 60C of the outer shoji screen 5C and inner shoji screen 6C. Therefore, this sliding window 1C also achieves the same effects as the sliding window 1. Parts with the same reference numerals as those in the sliding window 1 indicate parts with the same configuration, and therefore detailed explanations of these parts will be omitted below, with the above explanation being used as an example.

[0102] The outer and inner shoji screens 5C and 6C of the sliding window 1C are constructed by fitting a surface material G inside wooden frames 50C and 60C, which are rectangularly assembled wooden frames 51C and 61C, bottom frames 52C and 62C, end frames 53C and 63C, and joint frames 54C and 64C, similar to the outer and inner shoji screens 5 and 6 of the sliding window 1. As shown in Figures 25 and 26, cover materials 8 are attached to the exterior facing surfaces 51c and 61c, 52c and 62c, 53c and 63c, and 54c and 64c of the upper and lower frames 51C and 61C, the lower frames 52C and 62C, the end frames 53C and 63C, and the joint frames 54C and 64C, respectively.

[0103] The cover material 8 is made of an extruded shape formed from a metal material such as aluminum, and extends over the entire length of the upper frames 51C, 61C, lower frames 52C, 62C, end frames 53C, 63C, and joint frames 54C, 64C.

[0104] As shown in Figures 27 to 30, cover materials 81 of the same structure are attached to the upper frames 51C, 61C, lower frames 52C, 62C, door edge frames 53C, 63C, and the joining frame 54C of the outer shoji screen 5C. As shown in Figure 31, cover material 82 of a different shape from cover material 81 is attached to the joining frame 64C of the inner shoji screen 6C.

[0105] First, with reference to Figures 27 to 30, we will explain the cover material 81 that is attached to the upper frames 51C, 61C, lower frames 52C, 62C, and door edge frames 53C, 63C of the outer shoji screen 5C and inner shoji screen 6C, and the door frame 54C of the outer shoji screen 5C.

[0106] An engagement part 811 extending along the length of each stile is attached to the exterior facing surfaces 51c, 61c, 52c, 62c, 53c, 63c, 54c of the upper stiles 51C, 61C, lower stiles 52C, 62C, end stiles 53C, 63C, and joint stile 54C. The engagement part 811 has a pair of protruding pieces 811a, 811a that protrude toward the exterior side X1.

[0107] A pair of engagement pieces 812, 812 protruding toward the indoor side X2 is provided on the indoor side X2 surface of the cover material 81. The engagement pieces 812, 812 respectively engage with the protrusions 811a, 811a of the engagement portion 811 from the outdoor side X1 so as to sandwich them. As a result, the cover material 81 entirely covers the outdoor visible surfaces 51c, 61c, 52c, 62c, 53c, 63c, 54c of the upper stiles 51C, 61C, the lower stiles 52C, 62C, the door end stiles 53C, 63C, and the door frame 54C.

[0108] An indoor-side extending plate portion 813 extending toward the indoor-side X2 is formed on the indoor-side X2 surface of the cover material 81 at a position closer to the panel G than the engagement pieces 812, 812. The indoor-side extending plate portion 813 is arranged along the bottom of the storage portions 513, 613, 524, 624, 534, 634, 542 of each panel G when the cover material 81 is attached to the upper frames 51C, 61C, the lower frames 52C, 62C, the door end frames 53C, 63C, and the door frame 54C. The buffer materials 514, 614, 525, 625, 535, 635, 543 are arranged between the indoor-side extending plate portion 813 and the end face of the panel G. The cover material 81 is fixed to the upper frames 51C, 61C, the lower frames 52C, 62C, the end frames 53C, 63C, and the door frame 54C by screws (not shown) driven into the indoor extension plate portion 813.

[0109] A hollow portion 814 with a rectangular cross section is formed at the end of the cover material 81 closer to the panel G than the indoor-side extending plate portion 813. The hollow portion 814 protrudes from the indoor-side extending plate portion 813 toward the inside of the wooden frame 50C, 60C at the same height as the edge members 515, 615, 526, 626, 536, 636, and 544 arranged on the indoor side X2. A gasket 814a made of an elastic material such as rubber is provided on the indoor-side X2 surface of the hollow portion 814. As a result, the hollow portion 814 clamps and supports the end of the panel G between the edge members 515, 615, 526, 626, 536, 636, and 544, and the gasket 814a seals the gap between the panel G and the hollow portion 814. The cover material 81 can support the panel G with the highly strong hollow portion 814. Furthermore, the cover material 81 covers, from the outside X1, the portion of the spacer G2 in the surface material G where heat is easily transferred in the indoor-outdoor direction. Therefore, the upper frames 51C, 61C, the lower frames 52C, 62C, the door end frames 53C, 63C, and the door frame 54C have excellent heat insulation properties.

[0110] The exterior facing surfaces 51c, 61c, 52c, 62c, 53c, 63c, 54c of the upper frames 51C, 61C, the lower frames 52C, 62C, the end frames 53C, 63C, and the mating frame 54C have cutouts 51c1, 61c1, 52c1, 62c1, 53c1, 63c1, 54c1 cut out to a depth equivalent to the protrusion height of the engagement pieces 812, 812 and hollow portion 814 of the cover material 81 toward the interior side X2. The engagement portions 811 are arranged within the cutouts 51c1, 61c1, 52c1, 62c1, 53c1, 63c1, 54c1. The cutout portions 51c1, 61c1, 52c1, 62c1, 53c1, 63c1, and 54c1 are formed from the attachment portion of the engagement portion 811 to the accommodation portions 513, 613, 524, 624, 534, 634, and 542 of the face material G. As a result, a space S1 is formed between the cutout portions 51c1, 61c1, 52c1, 62c1, 53c1, 63c1, and 54c1 and the cover material 81.

[0111] Next, referring to Figure 31, we will explain the cover material 82 attached to the joining frame 64C of the inner shoji screen 6C. This cover material 82 differs from cover material 81 in that it is formed in a stepped shape corresponding to the stepped shape of the outdoor facing surface 64c of the joining frame 64C.

[0112] An engagement part 821 extending along the length of the interlocking frame 44C is attached to the stepped exterior facing surface 64c of the inner shoji screen 6C. The engagement part 821 has a pair of left and right protrusions 821a, 821a that protrude toward the exterior side X1.

[0113] A pair of engagement pieces 822, 822 protruding toward the indoor side X2 is provided on the indoor side X2 surface of the cover material 82. The engagement pieces 822, 822 respectively engage with the protrusions 821a, 821a from the outdoor side X1 so as to sandwich them. As a result, the cover material 82 covers part of the stepped outdoor visible surface 64c of the joining frame 64C.

[0114] The end of the covering material 82 on the panel G side bends toward the indoor side X2, following the stepped shape of the outdoor-facing surface 64c, as it approaches the inside of the wooden frame 60C. An indoor-side extension plate 823 extending toward the indoor side X2 is formed at the portion of the indoor-side X2 surface of the covering material 82 that is most bent toward the indoor side X2. The indoor-side extension plate 823 is positioned along the bottom of the storage section 642 of the panel G when the covering material 82 is attached to the panel stile 64C. A buffer material 643 is positioned between the indoor-side extension plate 823 and the end face of the panel G. The covering material 82 is fixed to the panel stile 64C with screws (not shown) driven into the indoor-side extension plate 823.

[0115] A hollow portion 824 with a rectangular cross section is formed at the end of the cover material 82 closer to the panel G than the indoor extension plate portion 823. The hollow portion 824 protrudes from the indoor extension plate portion 823 toward the inside of the wooden frame 60C at the same height as the rim member 644 arranged on the indoor side X2. A gasket 824a made of an elastic material such as rubber is provided on the indoor side X2 surface of the hollow portion 824. This allows the hollow portion 824 to clamp and support the end of the panel G between itself and the rim member 644, and the gasket 824a seals the gap between the panel G and the hollow portion 824. The cover material 82 can support the panel G using the highly durable hollow portion 824. Furthermore, the cover material 82 covers, from the outdoor side X1, the portion of the spacer G2 in the panel G where heat is easily transferred between the indoor and outdoor directions. Therefore, the panel frame 64C has excellent thermal insulation properties.

[0116] In this way, the wooden frames 50C, 60C of the sliding window 1C are respectively fitted with cover materials 81, 82, which protect the wooden frames 50C, 60C from wind, rain, and direct sunlight. The cover materials 81, 82 have hollows 814, 824, which make it difficult for heat from direct sunlight from the outside X1 to be transmitted to the wooden frames 50C, 60C. This reduces heat damage to the wooden frames 50C, 60C.

[0117] 32 and 33 show an example in which the above-mentioned cover material 81 is attached to the wooden frame 50B of a shoji screen 5B in a casement window 1B according to the third embodiment. Specifically, the cover material 81 is attached to the exterior-facing surfaces of the upper frame 51B1, the lower frame 52B1, and the left and right vertical frames 53B1 and 54B1 that make up the wooden frame 50B. Therefore, even in the casement window 1B, the wooden frame 50B of the shoji screen 5B is protected from wind, rain, and direct sunlight. Because the cover material 81 has a hollow portion 814, heat from direct sunlight from the exterior side X1 is less likely to be transmitted to the wooden frame 50B. Therefore, damage to the wooden frame 50B due to heat is suppressed.

[0118] In the above embodiments, the mounting pieces 214, 222, 233, 243 are attached to the outer surfaces 210b, 220b, 230b, 240b of the upper frame body 210, the lower frame body 220, and the vertical frame bodies 230, 240 by screws 214a, 222a, 233a, 243a, but they may also be attached to the indoor-facing surfaces 210d, 220d, 230d, 240d of the upper frame body 210, the lower frame body 220, and the vertical frame bodies 230, 240 by driving the screws 214a, 222a, 233a, 243a from the indoor side X2.

[0119] The sliding window 1, 1C, fixed window 1A, and casement window 1B according to this embodiment of the invention provide the following advantages: They each include wooden frames 2, 50A, and 2B attached to an opening 101 in a building skeleton 100, shoji screens 5, 6, 5A, 5B, 5C, and 6C fitted inside the wooden frames 2, 50A, and 2B, and an attachment 3 secured to the building skeleton 100 and positioned between the outer surfaces 210b, 220b, 230b, and 240b of the wooden frames 2, 50A, and 2B and the inner surfaces 101a, 101b, 101c, and 101d of the opening 101; the wooden frames 2, 50A, and 2B are secured to the attachment 3 by screws 21a, 22a, 23a, and 24a driven from the wooden frames 2, 50A, and 2B toward the attachment 3.

[0120] This allows easy access to the screws 21a, 22a, 23a, and 24a from inside the wooden frames 2, 50A, and 2B. Therefore, while the attachment 3 remains attached to the building skeleton 100, the wooden frames 2, 50A, and 2B can be easily removed from the attachment 3 without demolishing the exterior wall material 110 and the interior wall material 120. There is also no need to reapply the exterior wall material 110, the interior wall material 120, and the sealant 112 after replacing the wooden frames 2, 50A, and 2B.

[0121] In this embodiment, the attachment 3 has indoor mounting portions 313, 323, 333, 343 that extend toward the indoor side X2 beyond the wooden frame bodies 2, 50A, 2B, and at least the wooden frame bodies 2, 50A, 2B are fixed to the building main body 100 by screws 21a, 22a, 23a, 24a that pass through the indoor mounting portions 313, 323, 333, 343.

[0122] This allows access to the screws 21a, 22a, 23a, 24a from the indoor side X2 of the wooden frames 2, 50A, 2B, further improving workability when removing the wooden frames 2, 50A, 2B.

[0123] In this embodiment, the attachment 3 is assembled on four sides.

[0124] This allows the attachment 3, which has been assembled on all four sides in advance, to be attached to the opening 101 of the building skeleton 100, resulting in excellent workability in construction.

[0125] In this embodiment, the wooden frames 2, 50A, 2B are fixed to an attachment 3 attached to an opening 101 in a building skeleton 100.

[0126] This allows the wooden frames 2, 50A, 2B to be easily positioned by fitting them inside the attachment 3 attached around the opening 101 of the building body 100, so that the wooden frames 2, 50A, 2B can be easily fixed to the attachment 3.

[0127] In this embodiment, the wooden frames 2, 50A, 2B have mounting pieces 214, 222, 233, 243 at the end on the indoor side X2 that protrude toward the indoor side X2, and are fixed to the building structure 100 together with the indoor side mounting portions 313, 323, 333, 343 by screws 21a, 22a, 23a, 24a that pass through the mounting pieces 214, 222, 233, 243.

[0128] This allows mounting portions for the attachment 3 to be easily provided on the wooden frame bodies 2, 50A, 2B, and allows the wooden frame bodies 2, 50A, 2B and the attachment 3 to be easily fastened together using common screws 21a, 22a, 23a, 24a.

[0129] In this embodiment, notches 2103, 2202, 2303, 2403 are formed in the wooden frames 2, 50A, 2B at the attachment locations of the attachment pieces 214, 222, 233, 243.

[0130] As a result, the attachment portions of the attachment pieces 214, 222, 233, 243 on the wooden frames 2, 50A, 2B can be accommodated within the cutouts 2103, 2202, 2303, 2403, and therefore the attachment portions do not protrude beyond the outer surface of the wooden frames 2, 50A, 2B. Therefore, when attaching the wooden frames 2, 50A, 2B to the attachment 3, there is no interference with the attachment 3.

[0131] In this embodiment, a frame member 4 is provided on the indoor side X2 of the wooden frames 2, 50A, 2B, and the mounting pieces 214, 222, 233, 243 and the indoor side mounting portions 313, 323, 333, 343 are covered by the frame member 4.

[0132] This makes it possible to prevent the heads of the screws 21a, 22a, 23a, and 24a that fasten the wooden frames 2, 50A, and 2B to the attachment 3 from being visible, further improving the design.

[0133] In this embodiment, the attachment 3 has outdoor abutment pieces 312, 322, 332, 342 at the end of the outdoor side X1 that protrude toward the inside of the attachment 3, and the outdoor abutment pieces 312, 322, 332, 342 abut against the outdoor visible surfaces 210c, 220c, 230c, 240c of the wooden frames 2, 50A, 2B.

[0134] This allows the attachment 3 to support the ends of the wooden frames 2, 50A, 2B on the outside side X1.
