[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In this specification, the "prospective direction" is the direction along the indoor-outdoor direction in the fitting. The "finding direction" is the direction along the surface direction of the facing material (glass) in the fitting, and is a direction orthogonal to the prospective direction. The "finding surface" means each surface facing the outdoor side and the indoor side in the fitting, and the "prospective surface" means the surface extending in the indoor-outdoor direction in the fitting. In the drawings, the outdoor side of the fitting is designated as "outdoor side X1", and the indoor side of the fitting is designated as "indoor side X2". The horizontal direction when the fitting is viewed from the front is referred to as "left and right".

[0009] The stepped window 5 (fitting) of one embodiment is housed in the opening 11 formed in the building body 100. As shown in FIG. 1, the stepped window 5 is a stepped window in which three window portions are arranged adjacent to each other and connected in the vertical direction (longitudinal direction) of the finding direction. In the vertical direction of the opening 11 of the building body 100, a horizontal sliding window 6 (window portion) arranged in the upper stage, a fixed window 7 (FIX window, window portion) arranged in the middle stage, and a fixed window 8 (FIX window, window portion) arranged in the lower stage are provided. In the present embodiment, the horizontal sliding window 6 arranged in the upper stage, the fixed window 7 arranged in the middle stage, and the fixed window 8 arranged in the lower stage are arranged in this order from above to below, and are arranged adjacent to each other.

[0010] The horizontal sliding window 6 arranged in the upper section and the fitting-killing window 7 arranged in the middle section are configured as a connecting metal frame 31 (connecting part) that connects the horizontal sliding window 6 arranged in the upper section and the fitting-killing window 7 arranged in the middle section. As shown in Fig. 2, between the upper horizontal sliding window 6 and the middle fitting-killing window 7, there is no connecting member such as a plain surface, and the metal frames 621 and 711 of the lower frames 62 and upper frames 71 (adjacent members, horizontal members) of each other are integrally formed. The fitting-killing window 7 arranged in the middle section and the fitting-killing window 8 arranged in the lower section are configured as a connecting metal frame 32 (connecting part) that connects the fitting-killing window 7 arranged in the middle section and the fitting-killing window 8 arranged in the lower section. Between the middle fitting-killing window 7 and the lower fitting-killing window 8, there is no connecting member such as a plain surface, and the metal frames 721 and 811 of the lower frames 72 and upper frames 81 (adjacent members, horizontal members) of each other are integrally formed.

[0011] As shown in Figs. 1 and 2, the horizontal sliding window 6 is housed in the upper section of the opening 11 of the building body 100. As shown in Figs. 2 and 3, the horizontal sliding window 6 includes a frame body 60, a rectangular shoji 65 housed in the frame body 60, and a net part 66 arranged on the indoor side X2 of the shoji 65. The shoji 65 can be opened by pushing the door tip side to the outdoor side X1 and rotating it around a rotation axis (not shown) provided on the hanging side of the upper end part.

[0012] As shown in Figs. 2 and 3, the frame body 60 is a frame body framed in a rectangle by an upper frame 61, a lower frame 62, and left and right vertical frames 63 and 64. The upper frame 61, the lower frame 62, and the left and right vertical frames 63 and 64 are composed of metal frames 611, 621, 631, 641 and resin frames 613, 623, 633, 643 connected to the indoor side X2 of the metal frames 611, 621, 631, 641.

[0013] The metal frame 621 of the lower frame 62 is constituted by a part of the connecting metal frame 31, the details of which will be described later. The connecting metal frame 31 is a metal frame in which the metal frames 621 and 711 of the lower frame 62 and the upper frame 71 (adjacent members, horizontal members) are integrally formed at the connecting portion between the horizontal sliding window 6 arranged in the upper stage and the fitting window 7 arranged in the middle stage. The details of the connecting structure for connecting the metal frame 621 of the lower frame 62 of the upper horizontal sliding window 6 and the metal frame 711 of the upper frame 71 of the middle fitting window 7 will be described later.

[0014] The connecting metal frame 31 including the metal frames 611, 631, 641 and the metal frame 612 is formed of a metal material such as aluminum. The metal frame 621 is a part of the connecting metal frame 31 formed of a metal material such as aluminum. More specifically, the connecting metal frame 31 including the metal frames 611, 631, 641 and the metal frame 612 is formed by extrusion molding of an aluminum material. The resin frames 613, 623, 633, 643 are made of a synthetic resin such as vinyl chloride resin. More specifically, the resin frames 613, 623, 633, 643 are formed by extrusion molding of a synthetic resin such as vinyl chloride resin.

[0015] As described above, the horizontal sliding window 6 of the stepped window 5 according to the present embodiment is a composite fixture in which the outdoor side X1 is made of metal and the indoor side X2 is made of resin. Since the indoor side X2 of the metal frames 611, 631, 641 is covered with the resin frames 613, 633, 643 and the upper part of the indoor side X2 of the connecting metal frame 31 including the metal frame 621 is covered with the resin frame 623, the horizontal sliding window 6 of the stepped window 5 has excellent heat insulation properties and condensation is suppressed.

[0016] In addition, since the horizontal sliding window 6 of the stepped window 5 according to the present embodiment has a connecting metal frame 31 including metal frames 611, 631, 641 formed of a metal material and a metal frame 621 (upper frame 61, lower frame 62, and left and right vertical frames 63, 64), even if ultraviolet rays become stronger due to factors such as global warming, deterioration against ultraviolet rays can be suppressed more effectively than a resin sash in which the frame is formed only of resin. Also, since the frame 60 (upper frame 61, lower frame 62, and left and right vertical frames 63, 64) has a connecting metal frame 31 including metal frames 611, 631, 641 formed of a metal material such as aluminum and a metal frame 621, it is easier to recycle than a resin sash in which the frame is formed only of resin.

[0017] As shown in FIGS. 2 and 3, an operator handle 624 is provided on the lower frame 62. By rotating the operator handle 624, a rotational force is transmitted to the shoji 65 via the handle mechanism 625, and the shoji 65 can be opened and closed by rotating about a rotation axis on the suspension side provided at the upper end.

[0018] As shown in FIGS. 2 and 3, the shoji 65 includes an upper frame 651, a lower frame 652, left and right vertical frames 653, 654, a frame body 655 framed in a rectangle by these, and glass 656 fitted and fixed within the frame body 655.

[0019] The glass 656 is formed in a rectangle and fitted and fixed to the frame body 655. The glass 656 fitted into the frame body 655 of the shoji 65 is a multilayer glass including a plate glass 656a on the indoor side X2, a plate glass 656b on the outdoor side X1, and a spacer 656c sandwiched between these two plate glasses 656a, 656b at the ends of these two plate glasses 656a, 656b, and has excellent heat insulation properties.

[0020] As shown in FIGS. 1 and 2, the middle fitted window 7 is housed in the middle of the opening 11 of the building body 100. The lower fitted window 8 is housed in the lower part of the opening 11 of the building body 100. The fitted windows 7, 8 are also referred to as FIX windows.

[0021] As shown in FIGS. 2 and 4, the middle flush window 7 includes a frame body 70 and a rectangular glass 75 fitted and fixed in the frame body 70.

[0022] The glass 75 disposed in the middle flush window 7 and the glass 656 of the shutter 65 of the upper horizontal sliding window 6 disposed adjacent to the upper side are arranged side by side in the finding direction in a state where at least a part of the thickness portions in the expected direction of the glasses 75 and 656 overlap each other when viewed in the finding direction. In this embodiment, the glass surfaces on the outdoor side X1 and the indoor side X2 of the glass 75 disposed in the middle flush window 7 and the glass surfaces on the outdoor side X1 and the indoor side X2 of the glass 656 of the shutter 65 of the upper horizontal sliding window 6 disposed adjacent to the upper side are not arranged on the same plane (flush), but may be arranged on the same plane (flush). When the glass surfaces are arranged on the same plane (flush), the glass surfaces can be aligned on the same plane, so that the design property can be improved.

[0023] As shown in FIGS. 1 and 4, the frame body 70 is a frame body framed in a rectangle by an upper frame 71, a lower frame 72, and left and right vertical frames 73 and 74. The upper frame 71, the lower frame 72, and the left and right vertical frames 73 and 74 are composed of metal frames 711, 721, 731, and 741 and resin frames 713, 723, 733, and 743 connected to the indoor side X2 of the metal frames 711, 721, 731, and 741.

[0024] The metal frame 711 of the upper frame 71 of the flush window 7 disposed in the middle is constituted by a part of the connecting metal frame 31, details of which will be described later. The connecting metal frame 31 is a metal frame in which the metal frames 621 and 711 of the lower frames 62 and the upper frames 71 (adjacent members, horizontal members) are integrally formed at the connecting portion between the upper horizontal sliding window 6 disposed in the upper stage and the flush window 7 disposed in the middle stage. Details of the connecting structure connecting the metal frame 621 of the lower frame 62 of the upper horizontal sliding window 6 in the upper stage and the metal frame 711 of the upper frame 71 of the flush window 7 in the middle stage will be described later.

[0025] Also, the metal frame 721 of the lower frame 72 of the deadlight window 7 disposed in the middle section is constituted by a part of the connecting metal frame 32, which will be described in detail later. The connecting metal frame 32 is a metal frame in which the metal frames 721 and 811 of the lower frame 72 and the upper frame 81 (adjacent members, horizontal members) are integrally formed at the connecting part between the deadlight window 7 disposed in the middle section and the deadlight window 8 disposed in the lower section. Details of the connecting structure for connecting the metal frame 721 of the lower frame 72 of the deadlight window 7 in the middle section and the metal frame 811 of the upper frame 81 of the deadlight window 8 in the lower section will be described later.

[0026] The connecting metal frames 31 and 32 including the metal frames 731 and 741, and the metal frames 711 and 721 are formed of a metal material such as aluminum. The metal frame 711 is a part of the connecting metal frame 31 formed of a metal material such as aluminum. The metal frame 721 is a part of the connecting metal frame 32 formed of a metal material such as aluminum. More specifically, the connecting metal frames 31 and 32 including the metal frames 731 and 741, and the metal frames 711 and 721 are formed by extrusion molding of an aluminum material. The resin frames 713, 723, 733, and 743 are made of a synthetic resin such as vinyl chloride resin. More specifically, the resin frames 713, 723, 733, and 743 are formed by extrusion molding of a synthetic resin such as vinyl chloride resin.

[0027] On the indoor side X2 of the upper frame 71 and the left and right vertical frames 73 and 74, pressing edges 714, 734, and 744 are provided. The pressing edges 714, 734, and 744 press the peripheral edge of the glass 75 via the buffer members 714a, 734a, and 744a. Thereby, the peripheral edge of the glass 75 is clamped between the resin frames 713, 733, and 743 of the upper frame 71 and the left and right vertical frames 73 and 74 and the pressing edges 714, 734, and 744.

[0028] As shown in FIGS. 1, 2, and 4, the glass 75 is formed in a rectangular shape and is fitted and fixed into the frame body 30. As shown in FIGS. 2 and 4, the glass 75 is a multilayer glass including a plate glass 751 on the indoor side X2, a plate glass 752 on the outdoor side X1, and a spacer 753 sandwiched between these two plate glasses 751 and 752 at the ends of these two plate glasses, and has excellent heat insulation performance.

[0029] As described above, the fitting-in window 7 in the middle stage of the stepped window 5 according to the present embodiment is a composite fitting having a metal outdoor side X1 and a resin indoor side X2. The indoor sides X2 of the metal frames 731 and 741 are covered with resin frames 733 and 743, and the lower side of the indoor side X2 of the connecting metal frame 31 including the metal frame 711 is covered with the resin frame 713, and the upper side of the indoor side X2 of the connecting metal frame 32 including the metal frame 721 is covered with the resin frame 723. Therefore, the fitting-in window 7 in the middle stage of the stepped window 5 has excellent heat insulation performance and condensation is suppressed.

[0030] Further, since the fitting-in window 7 of the stepped window 5 according to the present embodiment has a frame body 70 (upper frame 71, lower frame 72, and left and right vertical frames 73 and 74) having metal frames 731 and 741 formed of a metal material and connecting metal frames 31 and 32 including metal frames 711 and 721, even if ultraviolet rays become stronger due to factors such as global warming, deterioration against ultraviolet rays can be suppressed more than that of a resin sash in which the frame body is formed only of resin. In addition, since the frame body 70 (upper frame 71, lower frame 72, and left and right vertical frames 73 and 74) has metal frames 731 and 741 formed of a metal material such as aluminum and connecting metal frames 31 and 32 including metal frames 711 and 721, it is easier to recycle than a resin sash in which the frame body is formed only of resin.

[0031] As shown in FIG. 2, the lower fitting-in window 8 includes a frame body 80 and a rectangular glass 85 fitted and fixed into the frame body 80. The configuration of the lower fitting-in window 8 is the same as that of the middle fitting-in window 7 except for the upper frame 81 and the lower frame 82. Therefore, for the configuration that is the same as that of the middle fitting-in window 7, corresponding reference numerals are given and the description thereof is omitted.

[0032] The glass 85 disposed in the lower blind window 8 and the glass 75 disposed in the middle blind window 7 disposed adjacent to the upper side are arranged side by side in the finding direction in a state where at least a part of the expected thickness portions of the glasses 85 and 75 facing each other overlap when viewed in the finding direction. In the present embodiment, the glass surface on the outdoor side X1 of the glass 85 disposed in the lower blind window 8 and the glass surface on the outdoor side X1 of the glass 75 of the middle blind window 7 disposed adjacent to the upper side are arranged on the same plane. The glass surface on the indoor side X2 of the glass 85 disposed in the lower blind window 8 and the glass surface on the indoor side X2 of the glass 75 of the middle blind window 7 disposed adjacent to the upper side are arranged on the same plane.

[0033] As shown in FIG. 1, the frame body 80 is a frame body framed in a rectangle by an upper frame 81, a lower frame 82, and left and right vertical frames 83 and 84. As shown in FIG. 2, the upper frame 81 and the lower frame 82 include a metal frame 811, 821 and a resin frame 813, 823 connected to the indoor side X2 of the metal frame 811, 821.

[0034] The metal frame 811 of the upper frame 81 of the blind window 8 disposed in the lower stage is constituted by a part of the connecting metal frame 32, similar to the configuration of the metal frame 811 of the upper frame 71 of the blind window 7 disposed in the middle stage described above. Although details will be described later, the connecting metal frame 32 is a metal frame in which the metal frames 721 and 811 of the lower frames 72 and the upper frames 81 (adjacent members, horizontal members) of each other are integrally formed at the connecting portion between the blind window 7 disposed in the middle stage and the blind window 8 disposed in the lower stage. Details of the connecting structure for connecting the metal frame 721 of the lower frame 72 of the middle blind window 7 and the metal frame 811 of the upper frame 81 of the lower blind window 8 will be described later.

Below the lower side of the indoor side X2 end of the connecting metal frame 32, the resin frame 813 of the upper frame 81 of the lower blind window 8 is connected.

[0054] The resin frame 723 is attached above the indoor side X2 of the connecting metal frame 32. The resin frame 723 is composed of a hollow structure having a plurality of hollow portions. The resin frame 723 has a main body frame 7231 having three hollow portions 7231a arranged side by side in the prospective direction, an outdoor side lower protrusion 7232 protruding downward on the end side of the outdoor side X1 of the main body frame 7231, and an extension plate 7233 extending from the upper end of the end of the indoor side X2 of the main body frame 7231 to the indoor side X2, and an indoor side lower protrusion 7234 protruding downward on the end side of the indoor side X2 of the main body frame 7231.

[0055] The outdoor side lower protrusion 7232 of the resin frame 723 engages with an engagement protrusion 3212b formed in the U-shaped opening 3212a of the outdoor side upper protrusion 3212 of the connecting metal frame 32. The indoor side lower protrusion 7234 of the resin frame 723 engages with a protrusion 3214 formed on the indoor side upper protrusion 3213 of the connecting metal frame 32. A water stop material 7231b is provided at the end of the outdoor side X1 of the main body frame 7231. The water stop material 7231b is pressed against the outdoor side X1 surface on the lower end side of the glass 75 by the resin frame 723.

[0056] The resin frame 813 is attached downward at the end of the indoor side X2 of the connecting metal frame 32. The resin frame 813 is composed of a hollow structure having a plurality of hollow portions. The resin frame 813 has a main body frame 8131 having three hollow portions 8131a arranged side by side in the prospective direction, an outdoor side upper protrusion 8132 protruding upward on the end side of the outdoor side X1 of the main body frame 8131, an extension plate 8133 extending from the lower end of the end of the indoor side X2 of the main body frame 8131 to the indoor side X2, and an indoor side upper protrusion 8134 protruding upward on the end side of the indoor side X2 of the main body frame 8131.

[0057] The upper outdoor protrusion 8132 of the resin frame 813 engages with an engaging protrusion 3221b formed in a U-shaped opening 3221a of a downward protrusion 3221 in the middle of the connecting metal frame 32.

The waterproofing material 8131b is pressed against the surface of the outdoor side X1 of the upper end side of the glass 85 by the resin frame 813.

[0058] As shown in FIG. 6, in a state where the lower frame 72 of the middle-stage deadlight window 7 and the upper frame 81 of the lower-stage deadlight window 8 are connected, on the indoor-side X2 surface of the end of the indoor side X2 of the portion where the lower frame 72 of the middle-stage deadlight window 7 and the upper frame 81 of the lower-stage deadlight window 8 are connected, a resin cover material 9 is detachably attached. Since the resin cover material 9 has the same configuration as the resin cover material 9 provided on the indoor-side X2 surface of the end of the indoor side X2 of the portion where the lower frame 62 of the horizontal sliding window 6 shown in FIG. 5 and the upper frame 71 of the deadlight window 7 are connected, as described above, the description thereof is incorporated by reference and omitted.

[0059] The stepped window 5 of this embodiment has the following effects. In the stepped window 5 of this embodiment, no connecting member is arranged between the adjacent upper horizontal sliding window 6 and the middle-stage deadlight window 7, and the metal frame 621 of the lower frame 62 of the horizontal sliding window 6 adjacent to each window part in the adjacent upper horizontal sliding window 6 and the metal frame 711 of the upper frame 71 of the deadlight window 7 are integrally formed, thereby constituting a connecting metal frame 31 that connects the adjacent upper horizontal sliding window 6 and the middle-stage deadlight window 7.

[0060] As a result, a connecting member can be eliminated between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, so that the connecting metal frame 31, which is the connecting part of the metal frame 621 of the lower frame 62 of the horizontal sliding window 6 and the metal frame 711 of the upper frame 71 of the blocking window 7, can be made thinner, and the design property can be improved. In addition, since a connecting member can be eliminated between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, the cost required for the connecting member can be reduced. Also, since a connecting member can be eliminated between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, the connecting part of the metal frame 621 of the lower frame 62 of the horizontal sliding window 6 and the metal frame 711 of the upper frame 71 of the blocking window 7 can be made thinner, and the areas facing the indoor side X2 and the outdoor side X1 can be reduced, so that the heat insulation performance can be improved. Further, since the connecting metal frame 31, which is the connecting part between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, is integrally formed, there is no need to consider water stoppage between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, so that the water stoppage performance can be improved.

[0061] Also, in the present embodiment, also at the connecting part between the adjacent middle blocking window 7 and the lower blocking window 8, similar to the connecting part between the adjacent upper horizontal sliding window 6 and the middle blocking window 7, no connecting member is arranged between the adjacent middle blocking window 7 and the lower blocking window 8, and the metal frame 721 of the lower frame 72 of the blocking window 7 and the metal frame 811 of the upper frame 81 of the blocking window 8 adjacent to each window part in the adjacent middle blocking window 7 and the lower blocking window 8 are integrally formed to constitute the connecting metal frame 32 as a connecting part. Thereby, also at the connecting part between the adjacent middle blocking window 7 and the lower blocking window 8, the same effects as those of the connecting part between the adjacent middle blocking window 7 and the lower blocking window 8 can be achieved.

[0062] In this embodiment, the connecting metal frame 31, which is the connecting portion between the adjacent middle - stage concealed window 7 and the lower - stage concealed window 8, has a hollow portion 3111a disposed on the indoor side X2 of the glass 656 of the shutter 65 of the upper - stage horizontal sliding window 6 and the glass 75 of the middle - stage concealed window 7. Thereby, in the connecting metal frame 31, which is the connecting portion between the adjacent middle - stage concealed window 7 and the lower - stage concealed window 8, the strength of the connecting metal frame 31 can be ensured by the hollow portion 3111a disposed on the indoor side X2. Also, since the hollow portion 3111a is disposed on the indoor side X2 of the glass 656 of the shutter 65 of the upper - stage horizontal sliding window 6 and the glass 75 of the middle - stage concealed window 7, even if the hollow portion 3111a has a large visible width (width in the vertical direction), it is difficult to see the large - width hollow portion 3111a from the outdoor side X1, so the design property can be improved.

[0063] In this embodiment, a resin cover material 9 is provided on the indoor side X2 of the connecting metal frames 31, 32 and is detachable from the connecting metal frames 31, 32. Thereby, since the indoor side X2 of the connecting metal frames 31, 32 can be covered by the resin cover material 9, the design property can be improved. Also, since the resin cover material 9 is detachable from the connecting metal frames 31, 32, when the resin cover material 9 is damaged or deteriorated, the resin cover material 9 can be replaced later.

[0064] In this embodiment, the frame body 60 of the horizontal sliding window 6 and the frame body 70 of the concealed window 7 at least have a metal frame formed of a metal material. Thereby, since the horizontal sliding window 6 and the concealed window 7 are composed of metal sashes, deterioration due to ultraviolet rays and the like can be suppressed compared to resin sashes in which the entire frame body is formed of a resin material.

[0065] In this embodiment, the types of the frame body 70 window parts of the adjacent side-sliding window 6 and the blind window 7 are different. The glass 75 arranged in the blind window 7 and the glass 656 of the shoji 65 of the adjacent side-sliding window 6 are arranged side by side in the finding direction in a state where at least a part of the expected thickness portions of the mutual glasses 75 and 656 overlaps in the finding direction. Conventionally, for example, when a side-sliding window and a blind window were arranged adjacent to each other, considering the heat insulation performance, the glass of the blind window was arranged closer to the indoor side. On the other hand, in the present disclosure, as a result of improving the heat insulation performance by slimming the connecting portion of the metal frame 621 of the lower frame 62 of the side-sliding window 6 and the metal frame 711 of the upper frame 71 of the blind window 7, the glass 75 arranged in the blind window 7 can be moved to the outdoor side, and it is possible to arrange them side by side in the finding direction in a state where at least a part of the expected thickness portions of the mutual glasses 75 and 656 overlaps in the finding direction, so that the design property can be improved.

[0066] As described above, one embodiment of the fitting of the present disclosure has been described, but the fitting of the present disclosure can be changed as appropriate.

[0067] For example, in the above embodiment, the frame body is constituted by an aluminum-resin composite sash including a metal frame and a resin frame, but the present disclosure is not limited to this. The frame body may be constituted by a metal sash constituted only by a metal material such as aluminum.

[0068] In the above embodiment, the fitting is constituted by a stepped window in which a plurality of window parts are arranged side by side in the vertical direction, but the present disclosure is not limited to this, and the fitting may be constituted by a continuous window in which a plurality of window parts are arranged side by side in the horizontal direction (lateral direction).
