[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A sliding window 1 constituting a fitting of a first embodiment will be described. In this specification, the "visible direction" refers to the face direction of the face panels 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction (i.e., the depth direction) of the face panels 35, 45. The "visible direction" also refers to the indoor / outdoor direction. The "visible surface" refers to the surface of the sliding window 1 facing the outside and the inside, respectively, and the "visible surface" refers to the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the sliding window 1 is designated as the outdoor side X1, and the indoor side of the sliding window 1 is designated as the indoor side X2.
[0010] As shown in Figures 1 and 2, a sliding window 1 is made up of a frame 2 attached to an opening in a building frame (not shown), and an outer shoji screen 3 placed on the outside X1 of the room, an inner shoji screen 4 placed on the inside X2 of the room, and a single screen 51 placed on the outside X1 of the outer shoji screen 3, all fitted inside the frame 2. The outer shoji screen 3 and inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the viewing direction.
[0011] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape. As shown in Figure 2, the upper frame 21 has an outdoor rail 211, an indoor rail 212, and a screen door rail 213. The lower frame 22 has an outdoor rail 221, an indoor rail 222, and a screen door rail 223.
[0012] In the lower frame 22, the outdoor rail 221 is disposed on the outdoor side of the lower frame 22 and protrudes upward. The indoor rail 222 is disposed on the indoor side X2 of the lower frame 22 and protrudes upward.
[0013] As shown in Figures 1 and 2, the outer shoji screen 3 is constructed by fitting a panel 35 made of three pieces of glass inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door tip side, and an outer joining frame 34, which is a vertical frame located on the door tail side. The outer shoji screen 3 is engaged with the outdoor rails 211, 221 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 32 of the outer shoji screen 3 is provided with a door roller 36 that rolls on the outdoor rail 221 of the lower frame 22.
[0014] The inner shoji screen 4 is constructed by fitting a panel 45 made of three pieces of glass inside a rectangular frame body 40 consisting of an upper frame 41, a lower frame 42, a vertical frame 43 located at the door tip, and an inner joining frame 44 located at the door tail. The inner shoji screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 42 of the inner shoji screen 4 is provided with a door roller 46 that rolls on the interior rail 222 of the lower frame 22.
[0015] The screen door 51 is engaged with the screen door rails 213, 223 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction.
[0016] The configuration of the lower frame 22 will be further described. As shown in FIG. 2, the lower frame 22 has a composite structure in which resin cover materials 224, 225 are attached to the inner surface of the metal lower frame 25, which is the lower frame body. This provides excellent thermal insulation and moisture resistance. The metal lower frame 25 is divided into an outdoor metal lower frame 26 and an indoor metal lower frame 27 between the outdoor rail 221 and the indoor rail 222. The outdoor metal lower frame 26 and the indoor metal lower frame 27 are connected by a resin connecting material 28. An L-shaped angle portion 226 is attached to the upper end of the indoor side X2 end of the resin covering material 225.
[0017] As shown in Figure 3, the outdoor metal lower frame 26 has a hollow structure having a hollow portion 262. A lower frame reinforcing member 6 having a generally L-shaped cross section is disposed within the hollow portion 262 of the outdoor metal lower frame 26.
[0018] As shown in Figure 4, the lower frame reinforcement member 6 is formed to extend in the left-right direction. The left-right length of the lower frame reinforcement member 6 is set appropriately. In this embodiment, the lower frame reinforcement member 6 is arranged, for example, on one side in the left-right direction on the outdoor side X1 of the lower frame 22.
[0019] As shown in Figure 3, the lower frame reinforcement 6 is fixed by screws 22a to the ceiling surface 263 of the hollow portion 262 formed by the underside of the upper plate portion 261 of the outdoor metal lower frame 26. When the lower frame 22 is deflected by the load of the outer sash 3, the lower frame reinforcement 6 supports the load of the outer sash 3, thereby reinforcing the outdoor metal lower frame 26.
[0020] The ceiling surface 263 of the hollow portion 262 is formed in a stepped shape and has a first ceiling surface 263a formed on the outside side X1, a second ceiling surface 263b formed on the inside side X2, and a step connection portion 263c connecting the first ceiling surface 263a and the second ceiling surface 263b.
[0021] A tapping hole 264 (engaged portion, convex portion) protruding downward from the ceiling surface 263 is provided on the ceiling surface 263 of the hollow portion 262. The tapping hole 264 is engaged with a hook engagement portion 63 (reinforcement support portion) of the lower frame reinforcement 6 described later.
[0022] The tapping holes 264 are holes into which screws can be inserted when assembling the longitudinal ends of the bottom frame 22 to a member such as a vertical frame. As shown in FIG. 3 , the tapping holes 264 are provided on the inner wall of the hollow portion 262 and protrude downward from the indoor side X2 end of the first ceiling surface 263a formed on the outdoor side X1 of the outdoor metal bottom frame 26. The tapping holes 264 are formed to open downward in a C-shape and extend in the longitudinal direction of the outdoor metal bottom frame 26.
[0023] As shown in Fig. 3, the lower frame reinforcement 6 is fixed to the second ceiling surface 263b with screws 22a. The lower frame reinforcement 6 has a vertical reinforcing surface portion 61 extending in the up-down direction and a horizontal reinforcing surface portion 62 extending from the upper end of the vertical reinforcing surface portion 61 toward the indoor side X2. The vertical reinforcing surface portion 61 has a hook engagement portion 63 (reinforcement support portion) that engages with a tapping hole 264 in the outdoor metal lower frame 26.
[0024] The vertical reinforcing surface portion 61 is formed by extending downward from near the end of the second ceiling surface 263b on the outside side X1. The lower end portion 611 of the vertical reinforcing surface portion 61 is close to or abuts the bottom surface 262a of the hollow portion 262. When the lower frame 22 is deflected by the load of the outer screen 3, the vertical reinforcing surface portion 61 is sandwiched between the ceiling surface 263 and the bottom surface 262a, thereby supporting the load of the outer screen 3.
[0025] The horizontal reinforcing surface 62 extends horizontally in a straight line from the upper end of the vertical reinforcing surface 61 toward the inside side X2 of the room. The horizontal reinforcing surface 62 is arranged along the second ceiling surface 263b and is fixed to the second ceiling surface 263b with screws 22a. When the lower frame 22 is deflected by the load of the outer shoji screen 3, the upper surface of the horizontal reinforcing surface 62 receives the load of the outer shoji screen 3 on its surface. The load received by the upper surface of the horizontal reinforcing surface 62 is transmitted to the vertical reinforcing surface 61 which is connected to the end of the horizontal reinforcing surface 62 on the outside side X1.
[0026] The hook engagement portion 63 protrudes from the upper part of the vertical reinforcing surface portion 61 toward the outside side X1. The tip of the hook engagement portion 63 is bent upward to form an L-shape. The L-shaped hook engagement portion 63 and the upper end portion of the vertical reinforcing surface portion 61 form a U-shaped engagement portion that is open upward as a whole.
[0027] When assembling the lower frame 22, the hook engagement portion 63 can be hooked onto and engaged with the tapping hole 264 before the lower frame reinforcement 6 placed inside the hollow portion 262 is secured with the screw 22a. This allows the hook engagement portion 63 to support the lower frame reinforcement 6 inside the hollow portion 262, preventing it from tipping over and facilitating assembly work. If the tapping hole 264 that protrudes into the hollow portion 262 is provided in the exterior metal lower frame 26, there is no need to provide a new structure for the hook engagement portion 63 to engage. This reduces manufacturing costs.
[0028] As shown in Fig. 3, a mounting bracket 7 to which a heat-foamed material 8 is fixed is fixed to the vertical reinforcing surface portion 61 of the bottom frame reinforcement 6. The mounting bracket 7 is formed in an L-shape in cross section and is fixed to the indoor side X2 surface at the vertical middle position of the vertical reinforcing surface portion 61 of the bottom frame reinforcement 6. The heat-foamed material 8 is fixed to the upper surface of the mounting bracket 7.
[0029] As shown in Fig. 3, the mounting bracket 7 has a vertical plate 71 and a horizontal plate 72. The vertical plate 71 is fixed with screws 73 to the surface of the vertical reinforcing surface portion 61 of the lower frame reinforcement member 6 on the indoor side X2 at a vertically intermediate position. The horizontal plate 72 extends from the upper end of the vertical plate 71 toward the indoor side X2.
[0030] The heat-foamed material 8 is fixed to the upper surface of the horizontal plate 72. As shown in Figures 3 and 4, the heat-foamed material 8 is disposed below the multiple drainage holes 227 in the hollow portion 262 on one end side in the left-right direction of the lower frame 22.
[0031] 4 and 5, the plurality of drain holes 227 are formed on one left-right side of the outdoor metal lower frame 26, and discharge water flowing on the upper surface of the outdoor metal lower frame 26 to the outside. The plurality of drain holes 227 are composed of a plurality of rectangular openings that penetrate the upper plate portion 261 of the outdoor metal lower frame 26 in the vertical direction.
[0032] 3, the heated foaming material 8 is disposed below and facing the plurality of drainage holes 227. In this way, when the heated foaming material 8 reaches a predetermined temperature due to a fire or the like, it foams and can block the openings of the drainage holes 227.
[0033] Next, a second embodiment will be described. The description of the first embodiment can be applied to points that are not described in the second embodiment. In the second embodiment, the same components as those in the first embodiment are assigned the same reference numerals as those in the first embodiment, and the description thereof will be omitted.
[0034] As shown in Fig. 6, the ceiling surface 263 of the hollow portion 262 in the second embodiment is formed by the lower surface of the upper plate portion 261 of the outdoor-side metal lower frame 26A of the lower frame 22A. The ceiling surface 263 of the hollow portion 262 is provided with an outdoor-side convex portion 265 (engaged portion, convex portion) and an indoor-side convex portion 266 (engaged portion, convex portion). The outdoor-side convex portion 265 is provided on the inner wall of the hollow portion 262, is located at the end of the first ceiling surface 263a on the outdoor-side X1 side on the indoor-side X2 side, and protrudes downward. The indoor-side convex portion 266 is provided on the inner wall of the hollow portion 262, is located midway in the indoor-outdoor direction on the second ceiling surface 263b on the indoor-side X2, and protrudes downward.
[0035] As shown in Fig. 6, a lower frame reinforcement member 6A is arranged in the hollow portion 262 of the outdoor metal lower frame 26A of the lower frame 22A. The lower frame reinforcement member 6A of the second embodiment has only the vertical reinforcing surface portion 61 and the horizontal reinforcing surface portion 62 of the lower frame reinforcement member 6 of the first embodiment, and does not have the hook engagement portion 63 of the lower frame reinforcement member 6 of the first embodiment.
[0036] The lateral reinforcing surface portion 62 is formed to extend in the indoor-outdoor direction. An outdoor-side engaging portion 621 (reinforcement material support portion) is formed at the end portion on the outdoor-side X1 side of the lateral reinforcing surface portion 62. An indoor-side engaging portion 622 (reinforcement material support portion) is formed at the end portion on the indoor-side X2 side of the lateral reinforcing surface portion 62.
[0037] The lateral reinforcement surface portion 62 is arranged between the outdoor side convex portion 265 and the indoor side convex portion 266, and the outdoor side engaging portion 621 engages with the outdoor side convex portion 265 of the outdoor side metal lower frame 26A, while the indoor side engaging portion 622 engages with the indoor side convex portion 266 of the outdoor side metal lower frame 26A.
[0038] During the assembly work of the lower frame 22A, the outdoor-side engaging portion 621 and the indoor-side engaging portion 622 of the lateral reinforcing surface portion 62 can be hooked onto and engaged with the outdoor-side convex portion 265 and the indoor-side convex portion 266 formed on the outdoor-side metal lower frame 26A before the sill reinforcement 6A placed in the hollow portion 262 is fixed with the screws 22a. This allows the outdoor-side engaging portion 621 and the indoor-side engaging portion 622 of the lateral reinforcing surface portion 62 to support the sill reinforcement 6A within the hollow portion 262 and prevent it from tipping over, making the assembly work easier.
[0039] Next, a third embodiment will be described. The description of the first embodiment can be applied to points that are not described in the third embodiment. In the third embodiment, the same components as those in the first embodiment are assigned the same reference numerals as those in the first embodiment, and the description thereof will be omitted.
[0040] 7, the ceiling surface 263A of the hollow portion 262 of the third embodiment is formed by the lower surface of the upper plate portion 261 of the outdoor metal lower frame 26B of the lower frame 22B within the hollow portion 262 of the lower frame 22B. The ceiling surface 263A of the hollow portion 262 is not formed in a stepped shape, but is formed as a horizontal surface on the outdoor side X1 and as a gently sloping curved surface on the indoor side X2.
[0041] A hooking protrusion 267 (protrusion) is formed on an inner surface 262b on the outdoor side X1 within the hollow portion 262 of the lower frame 22B. The hooking protrusion 267 is formed in an L-shape that opens downward.
[0042] As shown in Figure 7, a lower frame reinforcement member 6B is arranged within the hollow portion 262 of the outdoor-side metal lower frame 26B of the lower frame 22B. The lower frame reinforcement member 6B has a vertical reinforcing surface portion 61 and a horizontal reinforcing surface portion 62 similar to those of the first embodiment. The vertical reinforcing surface portion 61 of the lower frame reinforcement member 6B further has an outdoor-side protruding hook engagement portion 64 (reinforcement support portion) instead of the hook engagement portion 63 (reinforcement support portion) in the lower frame reinforcement member 6 of the first embodiment.
[0043] The outdoor protruding hook engagement portion 64 has a horizontal portion 641 extending from midway up and down on the vertical reinforcing surface portion 61 to the inner surface 262b of the outdoor side X1 within the hollow portion 262 of the lower frame 22B, and a protrusion 642 protruding upward from the outdoor side X1 end of the horizontal portion 641.
[0044] The protrusion 642 of the outdoor-side protruding hook engagement portion 64 engages with a hook protrusion 267 (engaged portion, protrusion) formed on the inner surface 262b of the outdoor-side X1 side in the hollow portion 262 of the lower frame 22B. The hook protrusion 267 is provided on the inner wall of the hollow portion 262.
[0045] When assembling the lower frame 22, the outdoor-side protruding hook engagement portion 64 can be hooked onto and engaged with the hook protrusion 267 before the lower frame reinforcement 6B placed inside the hollow portion 262 is fixed with the screws 22a. This allows the outdoor-side protruding hook engagement portion 64 to support the lower frame reinforcement 6B inside the hollow portion 262 and prevent it from tipping over, making the assembly work easier.
[0046] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.
[0047] For example, in the above embodiment, the horizontal reinforcing surface 62 of the lower frame reinforcement 6 is configured to extend only from the upper end of the vertical reinforcing surface 61 to the indoor side X2, but this is not limited thereto.
