[0007] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The fixture of this embodiment is a casement window 100, which can be selected from several types, such as a sliding window 1, 1A with a resin composite sash made of aluminum and resin, a sliding window 1C with only an aluminum stile and a frame made of composite material, and a sliding window 1B made entirely of aluminum.
[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 sliding window 1 shown in Figures 1 and 2 is a resin-composite sash, with the exterior side made of aluminum and the interior side made of resin. The aluminum and resin parts are joined together by fitting or the like. The resin-composite sash sliding window 1 has a frame 2, a shoji screen 3, an opening / closing mechanism 4, and a link mechanism 5. The sliding window 1 shown in Figures 1 and 2 is a cam latch-type sliding window 1 that is opened and closed by a cam latch handle 41. The sliding window 1 in Figures 1 and 2 has an interior shoji screen placed on the interior side, but this is not shown in the illustration to simplify the explanation.
[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 molding 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. The resin upper frame portion 21b abuts against the resin upper frame portion 31b of the upper frame 31, which will be described later, via an airtight material 92.
[0012] The lower frame 22 is a molded member arranged to extend substantially horizontally in the front 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 is an aluminum molded member extending in the front direction, and has an exterior portion 221 and an interior portion 222.
[0013] The outdoor portion 221 is located on the outdoor side of the lower frame 22, and is composed of a hollow structure that is roughly rectangular in cross section. The outdoor portion 221 has an upper surface 221a that extends in the viewing direction. The indoor portion 222 is on the indoor side of the outdoor portion 221, and extends upward beyond the upper surface 221a of the outdoor portion 221. The indoor portion 222 has an indoor side surface 222c, an engagement piece 222d, and a bottom 222e. The indoor side surface 222c is a surface that extends in the vertical direction on the indoor side of the indoor portion 222. The engagement piece 222d extends upward on the outdoor side of the indoor portion 222. The engagement piece 222d engages with the resin lower frame portion 22b. The bottom 222e is a surface that connects the engagement piece 222d and the indoor side surface 222c.
[0014] The resin lower frame portion 22b is positioned above the indoor side of the aluminum lower frame portion 22a. The resin lower frame portion 22b extends approximately horizontally along the front view direction. The outdoor end of the resin lower frame portion 22b is positioned facing the indoor end of the lower stile 32, which will be described later. An airtight material 91 is provided at the outdoor end of the resin lower frame portion 22b. The resin lower frame portion 22b, the engagement piece 222d of the aluminum upper frame portion 21a, the indoor side surface 222c, and the bottom 222e form a hollow structure portion that is approximately rectangular in cross section on the indoor side of the lower frame 22.
[0015] 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 frame 21 and the lower frame 22. The vertical frame 23 has an aluminum vertical frame portion 23a and a resin vertical frame portion 23b.
[0016] 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. The engagement pieces 232a and 232b 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 the indoor end, respectively.
[0017] The resin vertical frame portion 23b is disposed on the interior side of the frame body 2, on the inner side of the aluminum vertical frame portion 23a in the front direction. The resin vertical frame portion 23b engages with and is connected to the front direction ends of the engagement pieces 232a, 232b of the aluminum vertical frame portion 23a, and extends in the front direction.
[0018] The shoji screen 3 surrounds the glass portion 34 (described later) on all four sides and 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 portion 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.
[0019] As shown in Figure 1, the upper frame 31 is positioned below the upper frame 21 and extends in the forward direction. The upper frame 31 has an aluminum upper frame portion 31a, a resin upper frame portion 31b, and a glass holding portion 31c. The aluminum upper frame portion 31a is formed in a T-shape in cross section and has an exterior side surface 311 and an upper frame projection portion 312. The exterior side surface 311 extends downward from near the exterior end of the aluminum upper frame portion 21a. The upper frame projection portion 312 protrudes in a direction perpendicular to the exterior side surface 311 and extends in the forward direction on the inner periphery of the aluminum upper frame portion 21a.
[0020] The resin upper frame portion 31b engages with the indoor-side end of the upper frame projection portion 312 and extends vertically opposite the outdoor side surface 311. The outdoor 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 serves as the glass holding portion 31c. The resin upper frame portion 31b has an upper frame abutment portion 316 that protrudes toward the indoor side. The upper frame abutment portion 316 has multiple protrusions 3160 spaced apart in the vertical direction.
[0021] The lower frame 32 is positioned above the lower frame 22 and extends in the forward direction. 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 has an exterior side surface 321, a lower frame projection portion 322, and a hollow structure portion 324. The exterior side surface 321 has a flat surface that extends upward from near the exterior end of the lower frame 22. The lower frame projection portion 322 protrudes in a direction perpendicular to the exterior side surface 321 and extends in the forward direction on the inner periphery of the aluminum lower frame portion 22a. The hollow structure portion 324 is positioned below the lower frame projection portion 322 and is a hollow portion formed along the lower frame projection portion 322. The hollow structural portion 324 is composed of a part of the exterior side surface 321, a lower frame projection portion 322, a hollow projection piece 3241 facing the lower frame projection portion 322, and a hollow interior side surface 3242 facing the exterior side surface 321.
[0022] The resin lower frame portion 32b engages with the hollow indoor side surface 3242 of the hollow structural portion 324 and extends in the vertical direction on the indoor side surface of the lower frame 32. The resin lower frame portion 32b protrudes upward from the hollow indoor side surface 3242 and is positioned opposite a portion of the outdoor side surface 321. The resin lower frame portion 32b forms the indoor side surface of the lower frame 32. The resin lower frame portion 32b has a flat surface 325 and an abutment portion 326.
[0023] The flat surface 325 is a flat portion of the resin bottom frame portion 32b that extends in the vertical direction. The abutment portion 326 is formed on the underside of the flat surface 325 and protrudes from the flat surface 325 toward the interior side of the room. The abutment portion 326 is formed over a certain range in the vertical direction of the flat surface 325. The abutment portion 326 has multiple protrusions 3260. The protrusions 3260 protrude from the flat surface 325 toward the interior side of the room and are spaced apart in the vertical direction. Each of the protrusions 3260 protrudes the same length from the flat surface 325 toward the interior side, and the interior-side ends of the protrusions 3260 are aligned at the same distance from the flat surface 325 in the viewing direction. When the shoji screen 3 is closed, a portion of the protrusions 3260 abuts against the airtight material 91 provided on the exterior side of the resin bottom frame portion 22b of the bottom frame 22. The position where the protrusion 3260 contacts the airtight material 91 is the door contact position of the shoji screen 3 of the sliding window 1.
[0024] The exterior surface 321 of the lower frame 32, the lower frame projection 322, and the flat surface 325 of 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.
[0025] As shown in FIG. 2, the vertical stile 33 is disposed on the inner periphery of the vertical frame 23 and extends in the vertical direction. The vertical stile 33 has an aluminum vertical stile portion 33a, a resin vertical stile portion 33b, and a glass holding portion 33c. The aluminum vertical stile portion 33a has an exterior side surface 331 and a vertical stile projection portion 332. 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 stile projection portion 332 extends in the front direction from the exterior side surface 331. The resin vertical stile portion 33b engages with the interior-side end of the vertical stile projection portion 332 and extends in the front direction facing the exterior side surface 331. The exterior side surface 331, the vertical frame projection portion 332, and the resin vertical frame portion 33b form a cross section of the vertical frame 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.
[0026] The glass section 34 has glass 341 and a grating channel 342. The glass 341 is a surface material that closes the opening 201. The glass section 34 has double-glazed glass 341, with two pieces of glass 341 arranged on the outside and inside of the room with a spacer 344 sandwiched between them. The grating channel 342 is a rubber packing that has a roughly U-shaped cross section and holds the two pieces of glass 341. 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.
[0027] The opening / closing mechanism 4 is of a cam latch type and includes a cam latch handle 41 and a receiving portion 42. The cam latch handle 41 is rotatably attached to the bottom frame 32 of the shoji screen 3. The cam latch handle 41 includes a handle portion 411, a latch portion 412, and a pivot shaft 413. The handle portion 411 is a long, slender handle that a user can grasp and turn. The pivot shaft 413 connects the cam latch handle 41 to the bottom frame 32 and is a pivotally attached shaft. The latch portion 412 protrudes from the pivot shaft 413 in the opposite direction to 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 located on the vertical frame 23 side and has a recess that receives the latch portion 412. The receiving portion 42 is located within the resin bottom frame portion 22b.
[0028] The link mechanism 5 connects the shoji screen 3 and the frame body 2. The link mechanism 5 is composed of a flat stay or the like. The link mechanism 5 is disposed between the vertical frame 23 and the vertical stile 33.
[0029] Next, a resin composite sash sliding window 1A will be described. Explanations of parts common to the resin composite sash sliding window 1 already described will be omitted, and common parts will be described using the same reference numerals. The sliding window 1A shown in Figure 3 is an operator-type sliding window 1A that is opened and closed by an operator handle 41A. The sliding window 1A has a frame 2A, a shoji screen 3A, an opening / closing mechanism 4A, and a link mechanism 5A.
[0030] The upper frame 21A and vertical frame 23A of the frame body 2A in the sliding window 1A are generally similar in configuration to the upper frame 21 and vertical frame 23 of the above-mentioned sliding window 1. The upper frame 31A of the shoji screen 3A is also generally similar in configuration to the sliding window 1 and the sliding window 1A.
[0031] The lower frame 22A of the operator-operated sliding window 1A has an aluminum lower frame portion 22a and a resin lower frame portion 22bA. The aluminum lower frame portion 22a is an aluminum profile extending along the front direction and has an exterior portion 221 and an interior portion 222.
[0032] The outdoor section 221 is located on the outdoor side of the lower frame 22A and has an upper surface 221a extending in the viewing direction. The indoor section 222 is located indoors more than the outdoor section 221 and extends upward beyond the upper surface 221a of the outdoor section 221. The indoor section 222 has an upper surface 222a, a stepped surface 222b, an indoor side surface 222c, and a connecting piece 222f. The upper surface 222a is located higher than the upper surface 221a of the outdoor section 221. There is a step between the upper surface 221a of the outdoor section 221 and the upper surface 222a of the indoor section 222, and the stepped surface 222b of the indoor section 222 with the outdoor side extends in a direction approximately perpendicular to the upper surface 221a of the outdoor section 221. The upper part of the stepped surface 222b is disposed facing the resin lower frame section 32b. An airtight material 91 is attached to the upper part of the step surface 222b. The upper part of the step surface 222b and the underside of the abutment part 326A of the resin lower frame part 32b abut via the airtight material 91. The indoor side surface 222c is a surface that faces the step surface 222b and extends in the vertical direction on the indoor side. The connecting piece 222f protrudes upward from the upper surface 222a. The resin lower frame part 22bA is connected to the connecting piece 222f.
[0033] The resin lower frame portion 22bA is formed in a generally L-shape in cross section. The resin lower frame portion 22bA has an upright portion 223 and a lower frame upper surface portion 224. The upright portion 223 is connected to the connecting piece 222f of the indoor side portion 222 and stands up in the vertical direction. An operator handle 41A, which will be described later, is connected to the upright portion 223. The lower frame upper surface portion 224 extends in a direction generally perpendicular to the upright portion 223 and generally parallel to the upper surface 222a of the indoor side portion 222.
[0034] The link mechanism 5A is configured by a flat arm and is disposed between the upper frame 21A and the upper stile 31A, and between the lower frame 22A and the lower stile 32A.
[0035] The opening / closing mechanism 4A has an operator handle 41A and a connecting part (not shown). The operator handle 41A is connected to a handle (not shown), and rotating the handle opens and closes the shoji screen 3. The connecting part is a mechanism that connects the operator handle 41A and the shoji screen 3. The connecting part transmits the rotational movement of the operator handle 41A to a link mechanism 5A that connects the shoji screen 3 and the frame, thereby opening and closing the shoji screen 3.
[0036] The configuration of the upper frame 31A and the vertical frame 33A in the sliding window 1A is generally the same as that of the cam latch type sliding window 1. The configuration in which the glass portion 34 in the sliding window 1A is held on the inner periphery of the glass holding portions 31c, 32c, and 33c is the same as that of the sliding window 1.
[0037] In the bottom frame 32A, the protrusion 3260A of the resin bottom frame portion 32b abuts against the step surface 222b on the indoor side portion 222 of the bottom frame 22A via the airtight material 91. Comparing Figures 1 and 3, within a certain range in the vertical direction of the abutment portion 326A of the operator-type sliding window 1A, the door stop position that abuts against the airtight material 91 is lower than that of the cam latch-type sliding window 1. The shape of the resin bottom frame portion 32b itself is the same for the sliding window 1 and the sliding window 1A. Therefore, the shapes of the abutment portions 326, 326A and the protrusions 3260, 3260A are also the same.
[0038] 1 and 3, in the sliding window 1, the receiving portion 42 of the opening / closing mechanism 4 is disposed on the resin lower frame portion 22b. In the sliding window 1, the door stop position between the stile 32 and the lower frame 22 is formed between the outside end of the resin lower frame portion 22b and the abutment portion 326 of the resin lower frame portion 32b. In the sliding window 1A, the resin lower frame portion 22b has an upright portion 223 and an upper frame surface portion 224, and the operator handle 41A is attached to the upright portion 223. In the sliding window 1A, the door stop position between the stile 32A and the lower frame 22A is formed between the upper end side of the step surface 222b on the inside portion 222 of the aluminum lower frame portion 22a and the abutment portion 326 of the resin lower frame portion 32b. As a result, the door stop position of the sliding window 1A is lower than that of the sliding window 1. However, since the resin lower frame portion 32b has contact portions 326, 326A formed over a certain range in the vertical direction, the frames 2, 2A can contact the shoji screens 3, 3A at different door stop positions.
[0039] Next, we will explain a sliding window 1B made of aluminum sash, in which the frame 2 and shoji screen 3 are entirely made of metal. Explanations of parts common to the already-described sliding windows 1 and 1A made of resin composite sash will be omitted, and common parts will be explained using the same reference numerals. The sliding window 1B shown in Figures 4 and 5 is a cam latch-type sliding window 1B that is opened and closed using a cam latch handle 41B. The sliding window 1B has a frame 2B, a shoji screen 3B, an opening / closing mechanism 4B, and a link mechanism 5B. The sliding window 1B in Figures 4 and 5 has an indoor shoji screen located on the indoor side, but this is not shown to simplify the explanation.
[0040] As shown in Figure 4, the upper frame 21B of the frame body 2 does not have a resin upper frame portion 21b that covers the indoor side of the upper frame 21B. The outdoor and indoor sides of the upper frame 21B 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 21B in the front direction. The engagement piece 211 abuts against the indoor side of the upper frame 31 via the airtight material 92.
[0041] The lower frame 22B does not have a resin lower frame portion 22b that covers the indoor side of the lower frame 22B. The lower frame 22B is a molding material arranged to extend in a substantially horizontal direction along the lower edge of the opening 201. The lower frame 22B extends in the view direction and has an outdoor side portion 221 and an indoor side portion 222.
[0042] The outdoor section 221 is located on the outdoor side of the lower frame 22B and has an upper surface 221a extending in the viewing direction. The indoor section 222 is located indoors more than the outdoor section 221 and extends upward beyond the upper surface 221a of the outdoor section 221. The indoor section 222 has an upper surface 222a, a step surface 222b, an indoor side surface 222c, and a bottom 222e. The upper surface 222a is located higher than the upper surface 221a of the outdoor section 221. There is a step between the outdoor section 221 and the indoor section 222, and the step surface 222b of the indoor section 222 with the outdoor side extends in a direction approximately perpendicular to the upper surface 221a of the outdoor section 221. The upper part of the step surface 222b is arranged facing the resin lower frame section 32b. An airtight material 91 is attached to the upper part of the step surface 222b. The indoor side surface 222c is a surface that faces the step surface 222b and extends in the vertical direction on the indoor side. The bottom portion 222e is a surface that connects the step surface 222b and the indoor side surface 222c. The upper surface 222a, step surface 222b, indoor side surface 222c, and bottom portion 222e of the indoor side portion 222 form a hollow structure that is approximately rectangular in cross section.
[0043] 5, the vertical frame 23B has substantially the same configuration as the vertical frame 23 of the horizontal sliding window 1, except that it does not have the resin vertical frame portion 23b that covers the interior side of the vertical frame 23. In the vertical frame 23B, the space between the engagement pieces 232a, 232b is open toward the inner periphery of the frame body 2.
[0044] The upper frame 31B and vertical frame 33B have substantially the same configuration as the upper frame 31 and vertical frame 33 of the sliding window 1, except that the upper frame 31B does not have a resin upper frame portion 31b, and the vertical frame 33B does not have a resin vertical frame portion 33b. In the upper frame 31B and vertical frame 33B, instead of the resin upper frame portion 31b and the resin vertical frame portion 33b, aluminum interior side surfaces 313, 333 are arranged opposite the exterior side surfaces 311, 331. In the aluminum sash shoji screen 3B, the upper frame 31B and vertical frame 33B are entirely made of aluminum.
[0045] The lower frame 32B does not have a resin lower frame portion 32b. The lower frame 32B is arranged above the lower frame 22B. The lower frame 32B has an exterior side surface 321, a lower frame projection portion 322, and a hollow structure portion 324. The exterior side surface 321 has a flat surface that extends upward from near the exterior end of the lower frame 22. The lower frame projection portion 322 protrudes in a direction perpendicular to the exterior side surface 321 and extends in the projection direction on the inner side of the lower frame 32B. The hollow structure portion 324 is arranged below the lower frame projection portion 322 and is a hollow portion formed along the lower frame projection portion 322. The hollow structural portion 324 is composed of a part of the exterior side surface 321, a lower frame projection portion 322, a hollow projection piece 3241 facing the lower frame projection portion 322, and a hollow indoor side surface 3242B facing the exterior side surface 321. The hollow indoor side surface 3242B and the upper part of the step surface 222b of the lower frame 22B abut with an airtight material 91 interposed therebetween.
[0046] The hollow indoor side surface 3242B in the sliding window 1B forms the indoor side surface of the lower frame 32B. The hollow indoor side surface 3242B extends opposite the outdoor side surface 321, and its upper end is positioned at the same height as the upper end of the outdoor side surface 321. The hollow indoor side surface 3242B has a flat surface 325B and an abutment portion 326B. In the sliding window 1B, the flat surface 325B and the abutment portion 326B are formed integrally with the lower frame 32B.
[0047] The flat surface 325B is formed above the hollow room interior side surface 3242B and extends in the vertical direction. The abutment portion 326B is formed below the hollow room interior side surface 3242B and extends over a certain range in the vertical direction. The abutment portion 326B has multiple protrusions 3260B. The protrusions 3260B protrude from the flat surface 325B toward the interior side of the room and are spaced apart in the vertical direction. Each of the protrusions 3260B protrudes the same length from the flat surface 325B toward the interior side, and the interior-side ends of the protrusions 3260B are aligned at the same distance from the flat surface 325B in the viewing direction. A portion of the protrusions 3260B abuts against the airtight material 91 provided on the stepped surface 222b of the lower frame 22B when the shoji screen 3 is closed. The position where the protrusion 3260B abuts against the airtight material 91 is the door abutment position of the shoji screen 3B of the sliding window 1B.
[0048] The exterior side surface 321, the lower frame projection portion 322, and the hollow interior side surface 3242B form a cross section of the lower frame 32B 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.
[0049] The opening / closing mechanism 4B has a cam latch handle 41B of the same cam latch type as the sliding window 1. The cam latch handle 41 is connected to the upper part of the hollow room interior side surface 3242B of the lower frame 32B. The receiving portion 42 is arranged inside the hollow structural portion of the room interior portion 222 of the lower frame 22B. The opening of the recess of the receiving portion 42 is arranged on the upper surface 222a.
[0050] Next, referring to Figure 6, a sliding window 1C will be described in which the entire frame 30C of the shoji screen 3C is made of aluminum sash and the frame 2C is made of a composite material of aluminum and resin. Explanations of parts common to the already-described resin-composite sash sliding windows 1, 1A and aluminum sash sliding window 1B will be omitted, and common parts will be described using the same reference numerals. The sliding window 1C shown in Figure 6 is an operator-operated sliding window 1C that is opened and closed by an operator handle 41C. The sliding window 1C has a frame 2C, a shoji screen 3C, and an opening / closing mechanism 4C.
[0051] The configuration of the frame 2C is generally the same as the configuration of the frame 2A of the resin composite sash sliding window 1A shown in Figure 3. As with the sliding window 1A, an operator handle 41C is connected to the upright portion 223 of the resin lower frame portion 22bC of the lower frame 22C.
[0052] The configuration of the shoji screen 3C in the sliding window 1C is generally the same as the configuration of the shoji screen 3B shown in Figs. 4 and 5, in which the entire frame 30B is made of aluminum sash.
[0053] The position of the protrusion 3260C of the operator-type sliding window 1C that comes into contact with the airtight material 91 is lower than that of the cam latch-type sliding window 1 and sliding window 1B. The shape of the hollow interior side surface 3242C itself is the same as that of the sliding window 1B, which is made entirely of aluminum sash, and the sliding window 1C, which only has an aluminum sash frame 30C. Therefore, the shapes of the flat surfaces 325B, 325C, abutment portions 326B, 326C, and protrusions 3260B, 3260C of the sliding window 1B and sliding window 1C are also the same.
[0054] Comparing Figures 4 and 6, in the sliding window 1B, the receiving portion 42 of the opening / closing mechanism 4B receives the latch portion 412 of the cam latch handle 41. In the sliding window 1B, the contact position between the protrusion 3260B on the abutment portion 326B of the hollow interior side surface 3242B and the airtight material 91 provided on the step surface 222b of the bottom frame 22B is located higher than in the sliding window 1C. In the sliding window 1C, the operator handle 41C is tilted downward toward the front. Therefore, the contact position between the protrusion 3260C on the abutment portion 326C of the hollow interior side surface 3242C and the airtight material 91 provided on the step surface 222b of the bottom frame 22C is lower than in the sliding window 1B. That is, in the case of sliding window 1B and sliding window 1C, within the vertical range of abutment portions 326B, 326C of the same shape, the door stop position of sliding window 1C is lower than the door stop position of sliding window 1B.
[0055] However, even if the door stop positions of sliding window 1B and sliding window 1C are different vertically, abutment portions 326B, 326C are formed over a certain range in the vertical direction on hollow interior side surfaces 3242B, 3240C. Therefore, by changing the door stop position, i.e., the position where airtight material 91 hits abutment portion 326, vertically, it is possible to use lower frames 32B, 32C whose interior side surfaces have the same shape.
[0056] This embodiment offers the following advantages. The casement window 100, selected from multiple types of sliding windows 1, 1A, 1B, and 1C, differing in the door contact positions of the shoji screens 3, 3A, 3B, and 3C relative to the frame bodies 2, 2A, 2B, and 2C, has a common shape for the interior-facing surface of at least one side of the frame 30, 30A, 30B, and 30C of the shoji screens 3, 3A, 3B, and 3C. The interior-facing surface includes abutment portions 326, 326A, 326B, and 326C against which the frame bodies 2, 2A, 2B, and 2C can contact at different door contact positions. Because the shape of the interior-facing surfaces of the frame 30, 30A, 30B, and 30C is common, there is no need to change the type or shape of the frame 30, 30A, 30B, and 30C for each different type of fixture. This allows the shape of the frame 30, 30A, 30B, and 30C to be standardized. Therefore, when manufacturing multiple types of building materials, the number of components can be reduced, which reduces manufacturing costs and makes parts management easier.
[0057] According to this embodiment, the indoor surface is configured to include flat surfaces 325, 325A, 325B, and 325C, and abutment portions 326, 326A, 326B, and 326C protrude toward the indoor side from flat surfaces 325, 325A, 325B, and 325C. This makes it easier to adjust the position of the door stop in the prospective direction at the construction site if it becomes necessary to do so.
[0058] According to this embodiment, the abutment portions 326, 326A, 326B, and 326C are configured to include multiple protrusions 3260, 3260A, 3260B, and 3260C that protrude from the flat surfaces 325, 325A, 325B, and 325C toward the interior of the room and are spaced apart in the vertical direction. The multiple protrusions 3260, 3260A, 3260B, and 3260C protrude the same length from the flat surfaces 325, 325A, 325B, and 325C. Because the protrusions 3260, 3260A, 3260B, and 3260C are spaced apart in the vertical direction, it is possible to use the same component to accommodate differences in door stop positions, even if the door stop positions differ vertically depending on the sliding window 1, 1A, 1B, and 1C. Since the multiple protrusions 3260, 3260A, 3260B, and 3260C are arranged at a distance from the flat surfaces 325, 325A, 325B, and 325C, the shape can be easily adjusted, for example by cutting the protrusions 3260, 3260A, 3260B, and 3260C, if necessary, thereby increasing convenience.
[0059] According to this embodiment, the abutment portions 326, 326A, 326B, 326C are formed on the lower frames 32, 32A, 32B, 32C, and are formed over a certain range in the vertical direction of the resin lower frame portion 32b, the hollow interior side surface 3242B, and the hollow interior side surface 3242. This makes it easy to reduce the number of components when, for example, opening and closing mechanisms 4, 4A, 4B, 4C are provided on the underside of the sliding windows 1, 1A, 1B, 1C.
[0060] According to this embodiment, airtight material 91 is provided on step surface 222b, which is the exterior side of frame bodies 2, 2A, 2B, 2C, in contact with abutment portions 326, 326A, 326B, 326C. By providing airtight material 91 on frame bodies 2, 2A, 2B, 2C at the portions that contact abutment portions 326, 326A, 326B, 326C, it is possible to keep the gaps formed at the door contact positions between frame bodies 2, 2A, 2B, 2C and shoji screens 3, 3A, 3B, 3C3 airtight, and also to cushion the impact of the door contact.
[0061] According to this embodiment, the multiple types of casement windows 100 are sliding windows 1 and 1B with cam latch handles and sliding windows 1A and 1C with operator handles. This allows the components to be standardized between casement windows 100 with different opening and closing modes and opening and closing mechanisms, making it possible to reduce the number of parts.
[0062] The present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope of achieving the object of the present disclosure are included in the present disclosure. In the above-described embodiments, the shapes of the interior-facing surfaces of the lower frames 32 and 32A and the interior-facing surfaces of the lower frames 32B and 32B are common. However, it is sufficient that the shape of the interior-facing surface of at least one side of the frame 30 is common. For example, depending on the configuration of the casement window 100, an abutment portion may be formed on the upper frame to make the shape of the interior-facing surface common. The number of types of fittings that share a common surface shape is not limited to two, and any number of types may share the common surface shape.
[0063] FIG. 7 shows an example in which a flat surface 325D and abutment portion 326D are provided on the resin vertical stile portion 33b that forms the room-facing surface when the surface shape of the vertical stile 33D in a resin composite sash horizontal sliding window 1D is standardized. In this example, the abutment portion 326A protrudes from the flat surface 325D toward the room's interior and has multiple protrusions 3260D spaced apart along the viewing direction. The door contact position between the shoji screen 3D and the frame 2D is located on the vertical stile 33D side. By standardizing the shape of the room-facing surface of at least one side of the stile 30D, it is possible to standardize parts among multiple building fixtures.
[0064] Figure 8 shows another shape of the resin bottom frame of a resin bottom frame. The abutment portion 326F may be configured to protrude from the flat surface 325F toward the interior of the room and have a hollow structural portion 327. By making the interior surface of the hollow structural portion 327 common, parts can be standardized among multiple types of building materials with different door stop positions. The hollow structural portion 327 can improve the strength of the abutment portion 326F.
[0065] In the above embodiment, examples have been described using multiple types of fittings that differ in the constituent materials, such as metal or resin, of the frame 2 and the shoji 3, and in the opening and closing modes of the casement window 100. However, as long as the fittings have different door stop positions, fittings with different configurations may also be included. [Explanation of symbols]
