Embodiments for Carrying Out the Invention

[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 "search 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 "search 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 continuous window 1 (fitting) of the first embodiment is housed in the opening 11 formed in the building body 100. As shown in FIGS. 1 to 4, the continuous window 1 is a continuous window in which two window portions are arranged adjacent to each other in the left-right direction (lateral direction) of the finding direction, and is arranged on one side in the left-right direction of the opening 11 of the building body 100 (the left side in FIG. 1, the right side in FIG. 2). A fixed window 3 (FIX window, window portion, one window portion), and an opening window 2 (window portion, the other window portion) arranged on the other side in the left-right direction of the opening 11 of the building body 100 (the right side in FIG. 1, the left side in FIG. 2). The opening window 2 and the fixed window 3 are connected to each other by fastening the intermediate side vertical frames 24 and 33 (adjacent members, vertical members) to each other with screws 37 (fastening members) without arranging a connecting member such as a mullion between the opening window 2 and the fixed window 3.

[0010] As shown in FIG. 1, the opening window 2 is housed on the right side of the opening 11 of the building body 100 when viewed from the outdoor side X1, and on the left side of the opening 11 of the building body 100 when viewed from the indoor side X2 as shown in FIG. 2. As shown in FIGS. 2 and 3, the opening window 2 includes a frame body 20 and a rectangular shoji 25 housed in the frame body 20. The shoji 25 can be opened by pushing the door tip side to the outdoor side X1 and rotating it around a rotation shaft (not shown) provided on the suspension side.

[0011] As shown in FIGS. 2 and 3, the frame body 20 is a frame body framed in a rectangle by an upper frame 21, a lower frame 22, and left and right vertical frames 23 and 24. The upper frame 21, the lower frame 22, and the left and right vertical frames 23 and 24 are composed of metal frames 211, 221, 231, 241 and resin frames 213, 223, 233, 243 connected to the indoor side X2 of the metal frames 211, 221, 231, 241.

[0012] As shown in FIG. 3, in the upper frame 21 and the lower frame 22, the metal frames 211 and 221 are divided into two in the prospective direction into an outdoor side frame member 2111, 2211 and an indoor side frame member 2112, 2212. The outdoor side frame members 2111, 2211 and the indoor side frame members 2112, 2212 are both metal frame members, each consisting of an extruded profile extruded in the length direction from a metal material such as aluminum. Between the outdoor side frame members 2111, 2211 and the indoor side frame members 2112, 2212, connecting members 2113, 2213 (bridge materials) are arranged. The outdoor side frame members 2111, 2211 and the indoor side frame members 2112, 2212 are integrally connected by the connecting members 2113, 2213. The connecting members 2113, 2213 are made of a heat-insulating member such as resin, and block the heat transfer from the outdoor side frame members 2111, 2211 to the indoor side frame members 2112, 2212 in the upper frame 21 and the lower frame 22.

[0013] In the upper frame 21 and the lower frame 22, resin frames 213 and 223 are attached to the lower or upper part of the indoor side frame members 2112 and 2212 of the metal frames 211 and 221. The resin frames 213 and 223 are made of a synthetic resin such as vinyl chloride resin. More specifically, the resin frames 213 and 223 are formed by extruding a synthetic resin such as vinyl chloride resin. The resin frames 213 and 223 have extension pieces 213a and 223a that extend in the finding direction at the end of the indoor side X2. The extension pieces 213a and 223a are screwed to the frame member 101.

[0014] As shown in FIG. 2, the left and right vertical frames 23 and 24 are composed of a left vertical frame 23 arranged on the left side in the left-right direction of the opening 11 of the building body 100 and an intermediate vertical frame 24 arranged in the middle in the left-right direction of the opening 11 of the building body 100 when viewed from the indoor side X2.

[0015] As shown in Fig. 2, the left vertical frame 23 and the middle side vertical frame 24 have metal frames 231 and 241, and resin frames 233 and 243 connected to the indoor side X2 of the metal frames 231 and 241. The metal frames 231 and 241 are formed of a metal material such as aluminum. More specifically, the metal frames 231 and 241 are formed by extrusion molding of an aluminum material. The resin frame 233 of the left vertical frame 23 has an extension piece 233a extending in the finding direction at the end of the indoor side X2. The extension piece 233a is screwed and fixed to the frame member 101. The resin frames 233 and 243 are made of a synthetic resin such as vinyl chloride resin. More specifically, the resin frames 233 and 243 are formed by extrusion molding of a synthetic resin such as vinyl chloride resin.

[0016] The metal frame 241 of the middle side vertical frame 24 of the opening window 2 is fastened and fixed to the metal frame 331 of the middle side vertical frame 33 of the fixed window 3 with screws 37. Details of the connection structure connecting the metal frame 241 of the middle side vertical frame 24 of the opening window 2 and the metal frame 331 of the middle side vertical frame 33 of the fixed window 3 will be described later.

[0017] As described above, the opening window 2 of the continuous window 1 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 211, 221, 231, and 241 is covered with the resin frames 213, 223, 233, and 243, the opening window 2 of the continuous window 1 has excellent heat insulation properties and condensation is suppressed.

[0018] In addition, the opening window 2 of the continuous window 1 according to the present embodiment has a frame body 20 (upper frame 21, lower frame 22, and left and right vertical frames 23 and 24) configured with metal frames 211, 221, 231, and 241 formed of a metal material. Therefore, 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. Further, since the frame body 20 (upper frame 21, lower frame 22, and left and right vertical frames 23 and 24) has metal frames 211, 221, 231, and 241 formed of a metal material such as aluminum, it is easier to recycle than a resin sash in which the frame body is formed only of resin.

[0019] As shown in FIGS. 1 to 3, the shoji screen 25 includes an upper frame 251, a lower frame 252, left and right vertical frames 253 and 254, a frame body 255 formed into a rectangle by the frames, and a glass 256 fitted and fixed within the frame body 255. As shown in FIG. 2, the left and right vertical frames 253 and 254 are composed of a suspension-side vertical frame 253 arranged on the left side and a door-tip-side vertical frame 254 arranged on the right side when viewed from the indoor side X2.

[0020] As shown in FIGS. 2 and 3, the upper frame 251, the lower frame 252, and the left and right vertical frames 253 and 254 are composed of metal frames 2511, 2521, 2531, and 2541 and resin frames 2512, 2522, 2532, and 2542 connected to the indoor side X2 of the metal frames 2511, 2521, 2531, and 2541.

[0021] The metal frames 2511, 2521, 2531, and 2541 are formed of a metal material such as aluminum. More specifically, the metal frames 2511, 2521, 2531, and 2541 are formed by extrusion molding of an aluminum material. The resin frames 2512, 2522, 2532, and 2542 are composed of a synthetic resin such as vinyl chloride resin. More specifically, the resin frames 2512, 2522, 2532, and 2542 are formed by extrusion molding of a synthetic resin such as vinyl chloride resin.

[0022] As shown in FIGS. 1 to 3, the glass 256 is formed into a rectangle and fitted and fixed in the frame body 255. The glass 256 fitted in the frame body 255 of the shoji screen 25 is a multilayer glass including a plate glass 256a on the indoor side X2, a plate glass 256b on the outdoor side X1, and a spacer 256c sandwiched between these two plate glasses 256a and 256b at the ends of these two plate glasses 256a and 256b, and has excellent heat insulation properties.

When the indoor handle 257a or the outdoor handle 257b is rotated with the shoji 25 closed, the lock of the handle mechanism 258 is released. In this state, when the door end side of the shoji 25 is pushed out to the outdoor side X1, the shoji 25 is opened by rotating around the rotation axis on the suspension side. Also, when the door end side of the shoji 25 is pulled back to the indoor side X2 and the indoor handle 257a or the outdoor handle 257b is rotated, the shoji 25 is locked in the closed state by the handle mechanism 258.

[0024] As shown in FIG. 1, the fixed-pane window 3 is housed on the left side of the opening 11 of the building body 100 when viewed from the outdoor side X1, and on the right side of the opening 11 of the building body 100 when viewed from the indoor side X2 as shown in FIG. 2. As shown in FIGS. 2 and 4, the fixed-pane window 3 includes a frame body 30 and a rectangular glass 35 fitted and fixed in the frame body 30.
