[0007] An embodiment of the present disclosure will be described in detail below with reference to the drawings. The casement window 100 of this embodiment includes a vertical sliding window 1 and a horizontal sliding window 1B with a resin-composite sash in which the frames 30 and 30B are made of aluminum and resin, and a vertical sliding window 1A and a horizontal sliding window 1C with a metal sash in which the frames 30A and 30C are entirely made of aluminum. The vertical sliding window 1, the vertical sliding window 1A, the horizontal sliding window 1B, and the horizontal sliding window 1C have different shapes of the frames 30A, 30B, and 30C or different opening and closing modes. The casement window 100 is configured by selecting two or more of these casement windows and setting the distance between the components to a common dimension. The casement window 100 is a type of fixture that is placed in an opening 201 of a building 200 and connects the inside and outside of the building in an openable and closable manner. The vertical sliding windows 1, 1A and horizontal sliding windows 1B, 1C shown in Figs. 1 to 8 have indoor shoji screens arranged on the indoor side, but these are not shown in the drawings to simplify the explanation.

[0008] In this specification, the "view direction" refers to the left-right direction when viewed from the front of the casement window 100, and the "look-out direction" refers to the direction from inside to outside the casement window 100, i.e., the depth direction. The "up-down direction" refers to the top-to-bottom direction.

[0009] The vertical sliding window 1 shown in Figures 1 and 2 is a resin-composite sash, with the exterior side made of metal aluminum and the interior side made of resin. The aluminum and resin parts of the vertical sliding window 1 are joined together by fitting or the like. The vertical sliding window 1 has a frame 2, a shoji screen 3, an opening / closing mechanism 4, and a link mechanism 5. The vertical sliding window 1 is opened and closed by moving the vertical frames 23 and vertical stiles 33 of the frame 2 and shoji screen 3 in the forward direction.

[0010] The frame body 2 is a frame assembled in a rectangular shape around a substantially rectangular opening 201 in which the casement window 100 is disposed. The frame body 2 has an upper frame 21, a lower frame 22, and a pair of vertical frames 23 (see FIG. 2), each of which is elongated.

[0011] The upper frame 21 is a molded member arranged to extend substantially horizontally in the view direction along the upper edge of the opening 201. The upper frame 21 has an aluminum upper frame portion 21a and a resin upper frame portion 21b. The aluminum upper frame portion 21a has an engagement piece 211 that protrudes downward. The resin upper frame portion 21b engages with the engagement piece 211 of the aluminum upper frame portion 21a and covers the lower side of the aluminum upper frame portion 21a on the indoor side.

[0012] The lower frame 22 is a molding member arranged to extend substantially horizontally in the view direction along the lower edge of the opening 201. The lower frame 22 has an aluminum lower frame portion 22a and a resin lower frame portion 22b. The aluminum lower frame portion 22a has an engagement piece 221 that protrudes upward. The resin lower frame portion 22b engages with the engagement piece 221 of the aluminum lower frame portion 22a and covers the upper surface of the aluminum lower frame portion 22a on the interior side.

[0013] As shown in FIG. 2 , the vertical frame 23 extends in the vertical direction of the opening 201 and is arranged to connect the upper frame 21 and the lower frame 22 at both ends of the upper and lower frames 21 and 22. The vertical frame 23 has an aluminum vertical frame portion 23a and a resin vertical frame portion 23b. The aluminum vertical frame portion 23a has a projection portion 231 and an engagement portion 232. The projection portion 231 fits along the vertical edge of the opening 201 and covers the vertical edge of the opening 201 in the projection direction. The engagement portion 232 has engagement pieces 232a and 232b that protrude in the projection direction from approximately the center of the projection portion 231 in the projection direction and from the interior end of the frame body 2 toward the inner periphery of the frame body 2. The resin vertical frame portion 23b is arranged on the interior side of the frame body 2, inside the projection direction of the aluminum vertical frame portion 23a. The resin vertical frame portion 23b is engaged with and connected to the ends of the engagement pieces 232a, 232b of the aluminum vertical frame portion 23a in the front direction, and extends in the front direction.

[0014] The shoji screen 3 is arranged so as to be able to open and close on the inner periphery side of the frame body 2. The shoji screen 3 has a frame 30 and a glass section 34. The frame 30 has an elongated upper frame 31, a lower frame 32, and a pair of vertical frames 33. The frame 30 is formed in a roughly U-shaped cross section that opens toward the inner periphery side.

[0015] The upper frame 31 is positioned below the upper frame 21. The upper frame 31 has an aluminum upper frame portion 31a, a plastic upper frame portion 31b, and a glass holding portion 31c. The aluminum upper frame portion 31a is formed in a roughly T-shape in cross section and has an exterior side surface 311 that extends downward from the exterior end of the aluminum upper frame portion 21a, and an upper frame projection portion 312 that protrudes in a direction perpendicular to the exterior side surface 311 and extends in the projection direction on the inner periphery of the aluminum upper frame portion 21a. The plastic upper frame portion 31b engages with the interior end of the upper frame projection portion 312 and extends in the vertical direction facing the exterior side surface 311. The exterior side surface 311, the upper frame projection portion 312, and the resin upper frame portion 31b form a cross section of the upper frame 31 that is roughly U-shaped in cross section and opens downward, and the recess formed on the inside of this roughly U-shaped cross section becomes the glass holding portion 31c.

[0016] The lower frame 32 is positioned above the lower frame 22. The lower frame 32 has an aluminum lower frame portion 32a, a resin lower frame portion 32b, and a glass holding portion 32c. The aluminum lower frame portion 32a is formed in a roughly T-shape in cross section and has an exterior side surface 321 that extends upward from the exterior side of the aluminum lower frame portion 22a, and a lower frame projection portion 322 that protrudes in a direction perpendicular to the exterior side surface 321 and extends in the projection direction on the inner periphery of the aluminum lower frame portion 22a. The resin lower frame portion 32b engages with the interior-side end of the lower frame projection portion 322 and extends in the vertical direction opposite the exterior side surface 321. The resin lower frame portion 32b is positioned opposite the exterior end of the resin lower frame portion 22b via an airtight material 91. The exterior side surface 321, the lower frame projection portion 322, and the resin lower frame portion 32b form a cross section of the lower frame 32 that is roughly U-shaped in cross section and opens upward, and the recess formed on the inside of this roughly U-shaped cross section becomes the glass holding portion 32c.

[0017] The vertical frame 33 is disposed on the inner periphery side of the vertical frame 23. The vertical frame 33 has an aluminum vertical frame portion 33a, a resin vertical frame portion 33b, and a glass holding portion 33c.

[0018] The aluminum vertical frame portion 33a has an exterior side surface 331, a vertical frame projection portion 332, and a hollow structural portion 334. The exterior side surface 331 extends in the front direction from the inner periphery of the exterior end of the aluminum vertical frame portion 23a. The vertical frame projection portion 332 extends in the front direction from the exterior side surface 331. The hollow structural portion 334 is a hollow portion formed on the outer periphery of the vertical frame projection portion 332 in the front direction. The hollow structural portion 334 is composed of a part of the exterior side surface 331, the vertical frame projection portion 332, a hollow projection piece 3341 facing the vertical frame projection portion 332, and a hollow interior front surface 3342 facing the exterior side surface 331.

[0019] The resin vertical stile portion 33b engages with the indoor-side end of the vertical stile projection portion 332 and extends in the front direction facing the outdoor side surface 331. The outdoor side surface 331, the vertical stile projection portion 332, and the resin vertical stile portion 33b form a cross section of the vertical stile 33 that is roughly U-shaped in cross section and opens toward the inner periphery of the frame 30, and the recess formed on the inside of this roughly U-shaped cross section becomes the glass holding portion 33c.

[0020] The glass section 34 is held on the inner periphery of the frame 30. The glass section 34 has glass 341, a grating channel 342, and a setting block 343. The glass 341 is a surface material that closes the opening 201. The glass section 34 has double-glazed glass, with two pieces arranged on the outside and inside of the room with a spacer 344 sandwiched between them. The grating channel 342 is a rubber gasket that holds the two pieces of glass together and has a roughly U-shaped cross section. The grating channel 342 is inserted into the glass holding sections 31c, 32c, and 33c of the frame 30 and holds the end faces of the glass 341. The setting block 343 is a soft resin that is placed between the grating channel 342 and the upper frame projection section 312, the lower frame projection section 322, and the vertical frame projection section 332.

[0021] The opening and closing mechanism 4 is of a cam latch type and has a cam latch handle 41 and a receiving portion 42. The cam latch handle 41 is rotatably attached to the vertical frame 33 of the shoji screen 3. The cam latch handle 41 has a handle portion 411 and a latch portion 412. The handle portion 411 is a long, slender handle that a user can grasp and turn. The latch portion 412 protrudes in the opposite direction from the handle portion 411 from a rotation shaft 413 that rotatably connects the handle portion 411. The latch portion 412 engages and disengages with the receiving portion 42 by rotating the handle portion 411. The receiving portion 42 is positioned on the vertical frame 23 side and has a recess that receives the latch portion 412.

[0022] The link mechanism 5 connects the shoji screen 3 and the frame body 2. Specifically, the link mechanism 5 is composed of a flat stay or the like. The link mechanism 5 is disposed between the upper frame 31 and the upper frame 21, and below the lower frame 22 and the lower frame 32, and moves horizontally.

[0023] Next, we will explain a vertical sliding window 1A that is entirely made of metal aluminum. Explanations of parts that are common to the vertical sliding window 1 with a resin composite sash will be omitted, and common parts will be explained using the same reference numerals. The vertical sliding window 1A has a frame body 2A, a shoji screen 3A, and an opening / closing mechanism 4A. The shape of the frame body 2A and the frame 30A of the shoji screen 3A differs depending on whether the constituent material is a composite of aluminum and resin, or aluminum only.

[0024] As shown in Figure 3, the upper frame 21A of the frame body 2 does not have a resin upper frame portion 21b that covers the indoor side of the upper frame 21A. The outdoor and indoor sides of the upper frame 21A are integrated and extend in the front direction along the upper edge of the opening 201, with an engagement piece 211 protruding downward from the center of the upper frame 21A in the front direction. The engagement piece 211 faces the indoor side surface 313 of the upper frame 31 via the airtight material 92.

[0025] The lower frame 22A does not have a resin lower frame portion 22b that covers the indoor side of the lower frame 22A. The outdoor and indoor sides of the lower frame 22A are integrated and extend in the front direction along the lower edge of the opening 201. The indoor side of the lower frame 22A is formed to have a hollow structural portion 223 with a hollow interior. The upper end of the portion of the hollow structural portion 223 that extends vertically at approximately the center of the lower frame 22A in the front direction faces the indoor side of the lower frame 32A via the airtight material 91. The upper surface of the hollow structural portion 223 extends in an approximately horizontal direction on the indoor side of the lower frame 22A.

[0026] The vertical frame 23A does not have a resin vertical frame portion 23b that covers the interior side of the vertical frame 23A. The vertical frame 23A has a projection portion 231 and an engagement portion 232. The projection portion 231 fits along the edge of the opening 201 that extends in the vertical direction and covers the vertical edge of the opening 201 in the projection direction. The engagement portion 232 has engagement pieces 232a, 232b that protrude in the projection direction toward the inner periphery of the frame body 2 from approximately the center of the projection portion 231 in the projection direction and from the interior end portion. The space between the engagement pieces 232a, 232b is open toward the inside.

[0027] The upper frame 31A of the shoji screen 3 does not have a resin upper frame portion 31b. The upper frame 31A has an exterior side surface 311, an upper frame projection portion 312, and an interior side surface 313. The exterior side surface 311 extends in the vertical direction on the exterior side of the upper frame 31A. The upper frame projection portion 312 extends from the exterior side surface 311 toward the interior side in the projection direction. The exterior side surface 311 extends from the exterior end of the upper frame projection portion 312 so as to face the exterior side surface 311. The exterior side surface 311, the upper frame projection portion 312, and the interior side surface 313 form a glass holding portion 31c that is open downwards.

[0028] The lower frame 32A does not have a resin lower frame portion 32b. The lower frame 32A has an exterior side surface 321 extending to the outside of the room, a lower frame projection portion 322, and an interior side surface 323. The exterior side surface 321 extends in the vertical direction on the outside of the lower frame 32A. The lower frame projection portion 322 extends from the exterior side surface 321 toward the inside of the room in the projection direction. The interior side surface 323 extends from the interior-side end of the lower frame projection portion 322 and extends so as to face the exterior side surface 321. The exterior side surface 321, the lower frame projection portion 322, and the interior side surface 323 form a glass holding portion 32c that is open upward.

[0029] The vertical frame 33A does not have a resin vertical frame portion 33b. The vertical frame 33A has an exterior side surface 331, a vertical frame projection portion 332, an interior side surface 333, and a hollow structure portion 334. The exterior side surface 331 extends in the front direction from the inner periphery of the exterior end of the vertical frame 23A. The vertical frame projection portion 332 extends in the front direction from the exterior side surface 331. The interior side surface 333 extends in the front direction from the interior end of the vertical frame projection portion 332 toward the inner periphery. The hollow structure portion 334 is a hollow portion formed on the outer periphery of the vertical frame projection portion 332 in the front direction. The hollow structural portion 334 is composed of a part of the exterior side surface 331, a vertical stile projection portion 332, a hollow projection piece 3341 facing the vertical stile projection portion 332, and a hollow interior facing surface 3342 facing the exterior side surface 331. The exterior side surface 331, the vertical stile projection portion 332, and the interior side surface 333 form a cross section of the vertical stile 33A that is roughly U-shaped in cross section and opens toward the inner periphery of the frame 30, and the recess formed on the inside of this roughly U-shaped cross section becomes the glass holding portion 33c.

[0030] The structure in which the glass portion 34 is held on the inner periphery of the glass holding portions 31c, 32c, and 33c is the same as that of the vertical sliding window 1 having a resin composite sash.

[0031] The opening / closing mechanism 4A has a cam latch handle 41 and an engaging portion 414. In the vertical sliding window 1A, the indoor side of the vertical frame 23A is open, so the engaging portion 414 is disposed between the engaging pieces 232a, 232b and engages with the latch portion 412 of the cam latch handle 41. The engaging portion 414 has an engaging surface 414a that engages with the outdoor side of the latch portion 412 when the cam latch handle 41 is rotated.

[0032] As shown in Figures 1 to 4, the vertical sliding windows 1, 1A have a common dimension: distance D1 between the edge of the glass 341 and the interior-facing surface of the upper frame projection 312 of the upper frame 31, 31A. Also, a common dimension is distance D2 between the edge of the glass 341 and the interior-facing surface of the lower frame projection 322 of the lower frame 32, 32A. Also, a common dimension is distance D3 between the edge of the glass 341 and the interior-facing surface of the upper frame projection 332 of the vertical frame 33, 33A.

[0033] Next, we will explain the horizontal sliding window 1B with a resin composite sash. Explanations of parts common to the already explained vertical sliding window 1 with a resin composite sash and vertical sliding window 1A made of aluminum will be omitted, and common parts will be explained using the same reference numerals. The horizontal sliding window 1B differs from the vertical sliding windows 1 and 1A in the way it opens and closes. The horizontal sliding window 1B has a frame 2B, a shoji screen 3B, an opening and closing mechanism 4B, and a link mechanism 5B. The horizontal sliding window 1B is opened and closed by moving the bottom frame 22 and bottom stile 32 of the frame 2 and shoji screen 3 in the forward direction.

[0034] As shown in Figures 5 and 6, the upper frame 21B, lower frame 22B, and vertical frame 23B of the frame body 2 of the resin composite sash horizontal sliding window 1B are generally similar in configuration to the upper frame 21, lower frame 22, and vertical frame 23 of the resin composite sash vertical sliding window 1. The configuration of the upper frame 31B of the shoji screen 3 is also generally similar between the resin composite sash vertical sliding window 1 and the horizontal sliding window 1B. A link mechanism 5B connects the vertical frame 23B and the vertical frame 33B.

[0035] The bottom frame 32B of the horizontal sliding window 1B is located at a higher vertical height than the bottom frame 32 of the vertical sliding window 1. The vertical length of the exterior side surface 321B of the aluminum bottom frame portion 32a is longer than the bottom frame 32 of the vertical sliding window 1. A hollow structural portion 324 is formed below and along the bottom frame projection portion 322. The vertical length of the resin bottom frame portion 32b is longer than the length of the resin bottom frame portion 32b in the vertical sliding window 1. The resin bottom frame portion 32b extends upward from the lower end of the interior side surface of the hollow structural portion 324 and is positioned so as to face the exterior side surface 321B beyond the upper end of the hollow structural portion 324.

[0036] The vertical frame 33B of the horizontal sliding window 1B is shorter in the front direction than the vertical frame 33 of the vertical sliding window 1. The aluminum vertical frame portion 33a of the vertical frame 33B does not have a hollow structure portion 324. The aluminum vertical frame portion 33a is formed in a roughly T-shape in cross section and has an exterior side surface 331 and a vertical frame projection portion 332. The exterior side surface 331 extends in the front direction on the exterior side of the vertical frame 33B. The vertical frame projection portion 332 extends from approximately the center of the exterior side surface 331 in the front direction toward the interior side.

[0037] The configuration in which the glass portion 34 in the horizontal sliding window 1B is held on the inner periphery of the glass holding portions 31c, 32c, and 33c is the same as that of the vertical sliding windows 1 and 1A.

[0038] The opening / closing mechanism 4B is similar to the vertical sliding window 1 in that it has a cam latch handle 41 and a receiving portion 42. However, as shown in Figure 5, the cam latch handle 41 is rotatably attached to the resin lower frame portion 32b of the lower frame 32. When the shoji screen 3B is closed, the handle portion 411 extends from below to above, and the latch portion 412 of the cam latch handle 41 faces downward. The receiving portion 42 is positioned on the resin lower frame portion 22b of the lower frame 22. The receiving portion 42 is positioned so that it opens upward.

[0039] As shown in Figures 1 to 6, the vertical sliding windows 1, 1A and the horizontal sliding window 1B have the same distance D1 between the edge of the glass 341 and the interior side of the frame projection 312 of the frame 31, 31A, 31B, and the same distance D3 between the edge of the glass 341 and the interior side of the frame projection 332 of the frame 33, 33A, 33B. The distance D4 between the edge of the glass 341 and the interior side of the frame projection 322 of the frame 32B in the horizontal sliding window 1B is different from the distance D2 between the edge of the glass 341 and the interior side of the frame projection 322 of the frame 32, 32A in the vertical sliding windows 1, 1A. However, the distances D2 and D4 may be configured to be the same distance.

[0040] Next, we will explain the horizontal sliding window 1C, which is made entirely of aluminum. Explanations of parts common to the resin-composite sash vertical sliding window 1, metal vertical sliding window 1A, and resin-composite sash horizontal sliding window 1B already explained will be omitted, and the same reference numerals will be used for common parts. The horizontal sliding window 1C has a frame 2C, a shoji screen 3C, and an opening / closing mechanism 4C.

[0041] As shown in Figures 7 and 8, the upper frame 21C, lower frame 22C, and vertical frame 23C of the frame body 2 of the aluminum horizontal sliding window 1C are generally similar in configuration to the upper frame 21A, lower frame 22A, and vertical frame 23A of the aluminum vertical sliding window 1A. The upper frame 31C of the shoji screen 3C is also generally similar in configuration to the aluminum vertical sliding window 1A and horizontal sliding window 1C.

[0042] The bottom frame 32C of the horizontal sliding window 1C is located at a higher vertical height than the bottom frame 32A of the vertical sliding window 1A. The vertical length of the exterior side surface 321C of the bottom frame 32C is longer than that of the bottom frame 32A of the vertical sliding window 1A. A hollow structural portion 324 is formed below and along the bottom frame projection portion 322. The vertical length of the interior side surface 323 is longer than that of the interior side surface 323 of the vertical sliding window 1A. The interior side surface 323 extends upward from the lower end of the interior side surface of the hollow structural portion 324 and is positioned so as to face the exterior side surface 321 beyond the upper end of the hollow structural portion 324.

[0043] The vertical frame 33C of the horizontal sliding window 1C is shorter in the front direction than the vertical frame 33A of the vertical sliding window 1A. The vertical frame 33C does not have a hollow structure portion 324. The vertical frame 33C has an exterior side surface 331 extending to the exterior side, a vertical frame projection portion 332, and an interior side surface 333 extending from the exterior end of the vertical frame projection portion 332 and facing the exterior side surface 331.

[0044] The configuration in which the glass portion 34 in the horizontal sliding window 1C is held on the inner periphery of the glass holding portions 31c, 32c, and 33c is the same as in the vertical sliding windows 1 and 1A and the horizontal sliding window 1B.

[0045] The opening and closing mechanism 4C is generally the same as that of the resin composite sash sliding window 1B. The cam latch handle 41 is rotatably attached to the interior side surface 323 of the bottom frame 32C. When the shoji screen 3C is closed and locked, the handle portion 411 of the cam latch handle 41 extends from below to above, and the latch portion 412 faces downward. The receiving portion 42 is positioned in the hollow structure portion 324 of the bottom frame 22C. The receiving portion 42 is positioned so that it opens upward.

[0046] As shown in Figures 1 to 8, the vertical sliding windows 1, 1A and the horizontal sliding windows 1B, 1C have a common dimension of distance D1 between the edge of the glass 341 and the interior side of the frame projection portion 312 of the frame 31, 31A, 31B, 31C. The common dimension of distance D3 between the edge of the glass 341 and the interior side of the frame projection portion 332 of the frame 33, 33A, 33B, 33C.

[0047] The distance D4 between the end face of the glass 341 and the interior side of the stile projection 322 of the stile 32B in the horizontal sliding windows 1B and 1C is a common dimension. The distance D4 is different from the distance D2 between the end face of the glass 341 and the interior side of the stile projection 322 of the stile 32, 32A in the vertical sliding windows 1 and 1A. However, the distances D2 and D4 may be configured to be a common dimension.

[0048] 5 to 8, horizontal sliding window 1B made of resin composite sash and horizontal sliding window 1C made of aluminum have a common dimension in distance D1 between the edge of glass 341 and the interior side of frame projection portion 312 of upper frames 31B and 31C. Also, a common dimension is distance D4 between the edge of glass 341 and the interior side of frame projection portion 322 of lower frames 32B and 32C. Another common dimension is distance D3 between the edge of glass 341 and the interior side of frame projection portion 332 of vertical frames 33B and 33C. In other words, horizontal sliding window 1B and horizontal sliding window 1C have a common dimension in the distance between the edge of glass 341 and the edge of frame 30 on all four sides.

[0049] This embodiment provides the following advantages. The casement window 100 is selected from a plurality of vertical sliding windows 1, 1A and horizontal sliding windows 1B, 1C, etc., which differ in the shapes or opening / closing modes of the frames 30, 30A, 30B, 30C of the shoji screens 3, 3A, 3B, 3C. The shoji screens 3, 3A, 3B, 3C are configured to include frames 30, 30A, 30B, 30C and glass 341 held by the frames 30, 30A, 30B, 30C. The distance between the end face of the glass 341 and the frame 30, 30A, 30B, 30C is set to a common dimension on at least one side of the four perimeters of the frames 30, 30A, 30B, 30C. This allows the dimensions between the edge of the glass portion 34 and the projection of the frames 30, 30A, 30B, and 30C to be standardized between casement windows that have partially different outer shapes due to differences in materials, etc., such as differences in the shapes of the frames 30, 30A, 30B, and 30C, or differences in the opening and closing modes of the shoji screens 3. This allows parts to be standardized even if the shapes of the frames 30, 30A, 30B, and 30C differ depending on whether they are resin composite sashes or aluminum sashes, or if they are vertical sliding windows or horizontal sliding windows and have different opening and closing modes. This reduces the number of parts that make up the casement window 100, thereby reducing manufacturing costs and improving productivity.

[0050] According to this embodiment, the frame 30A of one of the vertical sliding window 1A and horizontal sliding window 1C of the selected casement window 100 is made of aluminum, and the frames 30 and 30B of the other vertical sliding window 1 and horizontal sliding window 1B are made of aluminum and resin. The number of parts can be reduced between casement windows with different shapes of the frames 30, 30A, 30B, 30C, achieving the same effect as above.

[0051] According to this embodiment, one of the selected casement windows 100 is a vertical sliding window 1, 1A, and the other is a horizontal sliding window 1B, 1C. The number of parts can be reduced between casement windows with different opening and closing modes, and the same effect as above can be achieved.

[0052] The distance between the end face of the glass 341 and the frames 30, 30A, 30B, and 30C is set to be the same for all four sides of the frames 30, 30A, 30B, and 30C. By setting a common dimension for all four sides, the number of parts can be further reduced.

[0053] The present disclosure is not limited to the above-described embodiment, and includes modifications, improvements, etc. within the scope of achieving the object of the present disclosure. The position of the side having the distance between the end face of the glass 341 and the frame 30 as a common dimension needs to be the same for at least one side, but may be two or three sides.

[0054] In the above embodiment, an example has been described in which the setting block 343 is disposed between the end face of the glass 341 and the inner surface of the frame 30. There may be cases in which nothing is disposed between the end face of the glass 341 and the inner surface of the frame 30. Also, fire prevention components or the like may be disposed.
