Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, there has been known a fitting comprising a frame body and a shoji screen placed within the frame body (see, for example, Patent Document 1). The shoji screen comprises a stile body and a surface material placed within the stile body. The vertical stiles placed at the left and right ends of the shoji screen have anti-sway members attached to the upper ends of the vertical stiles of the shoji screen to suppress the vibration of the upper rail of the upper frame of the frame body. At the upper end of the vertical stile of the shoji screen, the upper rail of the upper frame comes into contact with the anti-sway member attached to the upper end of the vertical stile, thereby forming an airtight line and ensuring airtightness.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-109090 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the upper rail of the upper frame is made of a hard metal material. The anti-vibration member attached to the upper end of the vertical frame is made of a hard resin material. When airtightness is ensured by the upper rail of the upper frame and the anti-vibration member attached to the upper end of the vertical frame, both the upper rail of the upper frame and the anti-vibration member are made of a hard material, which makes the adhesion weaker than when one of the members is made of a soft material. This can easily cause air leakage and reduce airtightness. Therefore, there is a need to improve the airtightness between the upper frame and the vertical frame of the shoji screen.

[0005] The present disclosure aims to provide a fixture that can improve the airtightness performance between the upper frame and the vertical frame of the shoji screen. [Means for solving the problem]

[0006] The present disclosure relates to a fixture comprising a frame body having an upper frame, a shoji screen disposed within the frame body and movable laterally, and an air leakage prevention member attached to the upper frame and positioned at a position where the upper end of the vertical frame of the shoji screen abuts when the shoji screen is in a closed position.

DETAILED DESCRIPTION OF THE INVENTION

[0008] 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.

[0009] As shown in Figures 1 to 3, a sliding window 1 is made up of a frame 2 attached to an opening in a building frame (not shown), and two shoji screens, an outer shoji screen 3 placed on the outside X1 and an inner shoji screen 4 placed on the inside X2, fitted inside the frame 2, as well as one screen 51 placed on the outside X1 of the outer shoji screen 3. The outer shoji screen 3 and inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the viewing direction.

[0010] 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 is provided with an exterior rail 211 (a downwardly protruding rail) and an interior rail 212 (a downwardly protruding rail). The upper frame 21 has a screen rail 213 on the exterior side X1 of the exterior rail 211. The exterior rail 211 is formed to protrude downward from the upper frame 21 at the exterior side X1 of the upper frame 21, and guides the upper end of the outer shoji screen 3. The interior rail 212 is formed to protrude downward from the upper frame 21 at the interior side X2 of the upper frame 21, and guides the upper end of the inner shoji screen 4.

[0011] The lower frame 22 is provided with an outdoor rail 221 and an indoor rail 222. The lower frame 22 has a screen rail 223 on the outdoor side X1 of the outdoor rail 221.

[0012] 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.

[0013] As shown in Figures 1 to 3, 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] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33 located on the door edge side, and outer joining frame 34 of the outer shoji screen 3 each have a composite structure in which resin frame materials 312, 322, 332, 342 are attached to the indoor side X2 of metal frame materials 311, 321, 331, 341. The upper frame 41, lower frame 42, vertical frame 43 located on the door edge side, and inner joining frame 44 of the inner shoji screen 4 each have a composite structure in which resin frame materials 412, 422, 432, 442 are attached to the indoor side X2 of metal frame materials 411, 421, 431, 441. This gives the outer shoji screen 3 and inner shoji screen 4 excellent thermal insulation and moisture resistance.

[0016] The upper frame 31 of the outer shoji screen 3 and the upper frame 41 of the inner shoji screen 4 have upper rail guides 313, 413 formed at the top and opening upward, as shown in Figure 2. Upper frame packing members 314, 414 are provided at the upper ends of the outdoor side X1 of the upper rail guides 313, 413, which abut against the outdoor side rail 211 and the indoor side rail 212 from the outdoor side X1, respectively. The upper frame packing members 314, 414 are made of a soft resin material.

[0017] The upper frame packing members 314, 414 are provided over the entire length of the upper frames 31, 41. The upper frame packing members 314, 414 ensure airtightness between the upper frames 31, 41 of the outer and inner shoji screens 3 and 4 and the outdoor rails 211 and indoor rails 212, respectively, and prevent wind from entering from the outdoor side X1.

[0018] The vertical frames 33, 43 arranged on the door edge side of the outer shoji 3 and the inner shoji 4 each have an open groove 333, 433 that opens outward from the door edge side in the left-right direction, as shown in Figure 3. At the outdoor end of the open groove 333, 433, a vertical frame packing member 334, 434 is provided that abuts from the outdoor side X1 against the protruding plate portion 233, 243 that protrudes inward in the left-right direction from the vertical frame 23, 24. The vertical frame packing member 334, 434 is made of a soft resin material.

[0019] The vertical stile packing members 334, 434 are provided over the entire length of the vertical stiles 33, 43. The vertical stile packing members 334, 434 ensure airtightness between the vertical stiles 33, 43 of the outer and inner shoji screens 3 and 4 and the protruding plate portions 233, 243 of the vertical frames, thereby preventing wind from entering from the outside X1.

[0020] In addition to the above-mentioned configuration, the outer shoji screen 3 has two upper anti-vibration members 52 (anti-vibration members), two lower anti-vibration members 53, and an intermediate anti-vibration member 6, as shown in Figure 1. In addition to the above-mentioned configuration, the inner shoji screen 4 has two upper anti-vibration members 52, two lower anti-vibration members 53, and an intermediate anti-vibration member 6.

[0021] The upper anti-sway members 52 are respectively provided at the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3, the upper end of the outer meeting frame 34 of the outer shoji screen 3, the upper end of the vertical frame 43 on the door edge side of the inner shoji screen 4, and the upper end of the inner meeting frame 44.

[0022] The upper anti-sway member 52 is formed in a U-shape that opens upward, as shown in Figure 2. An outdoor rail 211 and an indoor rail 212 are arranged in the upper open portion of the upper anti-sway member 52. As a result, the upper anti-sway member 52 restricts the swing of the outer shoji screen 3 and the inner shoji screen 4 in the indoor / outdoor direction at both left and right ends of the upper part of the outer shoji screen 3 and the inner shoji screen 4 when the outer shoji screen 3 and the inner shoji screen 4 slide in the front direction within the frame body 2.

[0023] Furthermore, when the outdoor rail 211 and the indoor rail 212 are arranged in the portion of the upper anti-sway member 52 that is open at the top, the outdoor rail 211 and the indoor rail 212, which are made of a hard metal material, abut against the inside portion of the upper end portion of the outdoor side X1 of the upper anti-sway member 52, which is made of a hard resin material. As a result, an airtight line is formed by the outdoor rail 211 and the indoor rail 212 abutting against the upper anti-sway member 52.

[0024] As shown in Figure 1, the lower anti-sway member 53 is provided at the lower end of the vertical frame 33 of the outer shoji screen 3, the lower end of the outer joining frame 34 of the outer shoji screen 3, the lower end of the vertical frame 43 of the inner shoji screen 4, and the lower end of the inner joining frame 44.

[0025] Although not shown in the figure, the lower anti-sway member 53 is formed to be open facing downwards. The outdoor rail 221 and the indoor rail 222 (see Figure 2) are arranged in the open portion of the lower anti-sway member 53. As a result, the lower anti-sway member 53 restricts the swing of the outer shoji screen 3 and the inner shoji screen 4 in the indoor / outdoor direction at both left and right ends of the lower part of the outer shoji screen 3 and the inner shoji screen 4 when the outer shoji screen 3 and the inner shoji screen 4 slide in the front direction within the frame body 2.

[0026] As shown in Figure 1, the intermediate anti-sway member 6 is disposed at a midpoint in the vertical direction on the vertical frames 33, 43 on the door edge side of the outer shoji screen 3 and the inner shoji screen 4, respectively. The intermediate anti-sway member 6 is attached to the open grooves 333, 433 of the vertical frames 33, 43 at a midpoint in the vertical direction on the door edge side of the outer shoji screen 3 and the inner shoji screen 4, as shown in Figure 1, as shown in Figure 3. The intermediate anti-sway member 6 is formed, for example, from an elastically deformable semi-hard resin material.

[0027] The intermediate anti-sway member 6 attached to the vertical frames 33, 43 on the door edge side of the outer shoji screen 3 and the inner shoji screen 4 is elastically deformed when the vertical frames 33, 43 are pressed against the vertical frames 23, 24 of the outer frame body 2 in the left-right direction when the outer shoji screen 3 and the inner shoji screen 4 are attached to the frame body 2, thereby preventing the outer shoji screen 3 and the inner shoji screen 4 from swaying.

[0028] The configuration of the frame 2 will be described in further detail. As shown in Figure 2, the upper frame 21 has a composite structure in which resin cover materials 215, 216 are attached to the inner surface of the metal frame 214, which is the frame main body. This provides excellent heat insulation and moisture resistance. The lower frame 22 has a composite structure in which resin cover materials 226, 227 are attached to the inner surface of the metal frame 224, which is the frame main body. This provides excellent heat insulation and moisture resistance.

[0029] As shown in Figure 3, the vertical frame 23 located on the door edge side of the outer shoji screen 3 has a composite structure in which a resin cover material 232 is attached to the inner surface of a metal frame body 231, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. The vertical frame 24 located on the door edge side of the inner shoji screen 4 has a composite structure in which a resin cover material 242 is attached to the inner surface of a metal frame body 241, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance.

[0030] As shown in Figures 1 to 4, when the outer shoji screen 3 is in the closed position, an air leakage prevention member 7 is attached to the underside of the upper frame 21 above the vertical frame 33 located on the door edge side of the outer shoji screen 3. The air leakage prevention member 7 is formed in a block shape.

[0031] As shown in Figure 4, the air leakage prevention member 7 is provided on the underside of the upper frame 21, between the outdoor rail 211 and the screen rail 213. As shown in Figures 5 and 6, the air leakage prevention member 7 is disposed above the vertical frame 33 on the door tip side of the outer screen 3 in a position where it abuts against the upper end of the outer screen 3 when the outer screen 3 is in the closed position.

[0032] As shown in Figures 5 and 6, when viewed from above in a plan view, the air leakage prevention member 7 is arranged in a range spanning the vertical stile gasket member 334, the upper anti-vibration member 52, and the upper stile gasket member 314 in the left-right direction.

[0033] As shown in Figures 4 to 6, the air leakage prevention member 7 is positioned so that when the outer shoji screen 3 is in the closed position, it abuts the upper end of the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door tip side of the outer shoji screen 3.

[0034] The air leak prevention member 7 has an attachment portion 71, a plurality of fin portions 72, and a plurality of sponge portions (cushion portions) 73. As shown in Fig. 4, the attachment portion 71 has a protruding engagement portion 711 that protrudes upward. An engagement protrusion 711a of the protruding engagement portion 711 is engaged with and fixed to a tapping hole 217 provided on the lower surface of the upper frame 21.

[0035] As shown in Figures 5 and 6, the multiple fin portions 72 are formed in the shape of plates extending downward from the underside of the mounting portion 71. Each of the multiple fin portions 72 is formed from a thin plate-like member with its surface facing left and right (the facing direction), and is arranged side by side at intervals in the left and right direction (the direction of movement of the outer screen 3). Each of the multiple fin portions 72 is formed from an elastic plate-like material. The fin portions 72 are formed, for example, from a soft resin material.

[0036] The lower ends of the multiple fin portions 72 elastically deform while abutting against the upper end of the outer shoji screen 3 when the outer shoji screen 3 moves from the open position to the closed position, and are positioned so that no gap occurs between the upper frame 21 and the outer shoji screen 3. When the outer shoji screen 3 is in the closed position, the lower ends of the multiple fin portions 72 abut against the upper end of the upper anti-vibration member 52 provided at the upper end of the outer shoji screen 3. This allows the fin portions 72 to close the gap between the upper frame 21 and the upper end of the vertical stile 33 on the door tip side of the outer shoji screen 3, improving airtightness.

[0037] The multiple sponge portions 73 are each arranged between adjacent fin portions 72. Each of the multiple sponge portions 73 is formed in a rectangular parallelepiped shape. Each of the multiple sponge portions 73 is fixed to the underside of the mounting portion 71. The sponge portions 73 support the fin portions 72 to prevent them from falling over when the tip of the fin portion 72 abuts against the upper end of the upper anti-sway member 52 arranged at the upper end of the vertical frame 33 on the door tip side and bends in the direction of movement of the outer shoji screen 3 and falls over. The sponge portions 73 function as cushion portions with cushioning properties and are formed from a foamed resin material.

[0038] The lower ends of the multiple sponge portions 73 are located slightly higher than the lower ends of the multiple fin portions 72. When the fin portion 72 abuts against the upper end of the upper anti-sway member 52 provided at the upper end of the outer shoji screen 3, the lower end of the sponge portion 73 is positioned in a position abutting or close to the upper end of the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3. When the lower end of the sponge portion 73 abuts against the upper end of the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3, the sponge portion 73, together with the fin portion 72, can close the gap between the upper frame 21 and the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3, thereby improving airtightness.

[0039] When the outer screen 3 moves from the open position (see Figure 7) to the closed position (see Figure 6), the above-mentioned air leakage prevention member 7 abuts against the upper end of the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door tip side of the outer screen 3, between the outdoor rail 211 and the screen door rail 213. As a result, the air leakage prevention member 7 abuts against the upper end of the vertical frame 33 on the door tip side of the outer screen 3 on the outdoor side X1, which is further outside than the position where the outdoor rail 211 and the upper anti-sway member 52 abut, thereby further improving the airtightness between the upper frame 21 and the vertical frame 33 of the outer screen 3.

[0040] The first embodiment provides the following advantages: The sliding window 1 of this embodiment comprises a frame body 2 having an upper frame 21, an outer shoji screen 3 that is disposed within the frame body 2 and is movable left and right, and an air leakage prevention member 7 that is attached to the upper frame 21 and disposed in a position where it abuts against the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3 when the outer shoji screen 3 is in the closed position. As a result, when the outer shoji screen 3 is in the closed position, the air leakage prevention member 7 abuts against the upper end of the vertical frame 33 on the door edge side of the outer shoji screen 3, thereby improving the airtightness between the upper frame 21 and the vertical frame 33 of the outer shoji screen 3.

[0041] Furthermore, in this embodiment, the air leakage prevention member 7 is positioned so that it abuts against the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door tip side when the outer shoji screen 3 is in the closed position. This improves the airtightness between the upper frame 21 and the vertical frame 33 of the outer shoji screen 3 at the position where the air leakage prevention member 7 abuts against the upper anti-sway member 52 when the outer shoji screen 3 is in the closed position.

[0042] Furthermore, in this embodiment, the air leakage prevention member 7 has a plurality of soft fin portions 72 arranged in a line at intervals in the direction of movement of the outer screen 3, and a sponge portion 73 arranged between adjacent fin portions 72. As a result, the lower ends of the soft fin portions 72 elastically deform while abutting against the upper end of the outer screen 3, and the lower ends of the soft sponge portions 73 are arranged in a position abutting or close to the upper end of the outer screen 3, so that by having two types of members, the soft fin portions 72 and the soft sponge portions 73, it is possible to ensure airtight performance by following the movement of the outer screen 3. Furthermore, because the sponge portions 73 are arranged between adjacent fin portions 72, the sponge portions 73 can stably support the fin portions 72 to prevent the fin portions 72 from falling over.

[0043] Next, a second embodiment and a third embodiment will be described. The description of the first embodiment can be applied to points that are not described in the second and third embodiments. In the second and third embodiments, 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.

[0044] A second embodiment will now be described. As shown in Figures 8 and 9, the second embodiment includes an air leak prevention member 8 instead of the air leak prevention member 7 of the first embodiment. The air leak prevention member 8 of the second embodiment is attached to the upper frame 21, as shown in Figure 8, in the same way as the first embodiment.

[0045] The air leakage prevention member 8 is formed in a frame shape that is elastically deformable while having an elastic repulsive force. For example, the air leakage prevention member 8 is formed in a frame shape from a hard resin material that is elastically deformable while having an elastic repulsive force. As shown in Figure 8, when the outer screen 3 is in the closed position, the air leakage prevention member 8 is positioned to abut against the upper end of the upper anti-sway member 52 provided at the upper end of the vertical frame 33 on the door tip side of the outer screen 3.

[0046] As shown in FIG. 8, the air leak prevention member 8 has an attachment plate portion 81, a support plate portion 82 fixed below the attachment plate portion 81, and an elastically deformable frame portion 83.

[0047] The mounting plate portion 81 is formed in the shape of a plate that has a width in the indoor-outdoor direction and extends in the left-right direction. The mounting plate portion 81 is attached to the lower surface of the upper frame 21. The support plate portion 82 is fixedly disposed along the lower side of the mounting plate portion 81.

[0048] The elastically deformable frame portion 83 is connected to the support plate portion 82 below the support plate portion 82. The elastically deformable frame portion 83 is elastically deformable when the outer shoji screen 3 comes into contact with and crushes it as the outer shoji screen 3 moves left and right.

[0049] The elastically deformable frame portion 83 is formed with an open top, and is formed into a trapezoidal frame shape including the upper support plate portion 82. The elastically deformable frame portion 83 has a base end side inclined plate portion 831, a bottom side plate portion 832, and an open end side inclined plate portion 833 (inclined plate portion).

[0050] The base-end inclined plate portion 831 is disposed on one side in the left-right direction of the elastically deformable frame portion 83 (the left side in FIG. 8), and extends obliquely downward from the support plate portion 82. As it goes from top to bottom, the base-end inclined plate portion 831 extends obliquely downward for a predetermined length, inclining from one side in the left-right direction of the frame body 2 (the left side in FIG. 8) to the other side (the right side in FIG. 8).

[0051] The bottom side plate portion 832 is formed in a plate shape extending in the left-right direction at the bottom of the elastically deformable frame portion 83. The bottom side plate portion 832 extends a predetermined length from the lower end of the base end side inclined plate portion 831 to the other side in the left-right direction.

[0052] The open-end inclined plate portion 833 extends obliquely upward from the other end of the bottom side plate portion 832 in the left-right direction. The open-end inclined plate portion 833 extends a predetermined length, inclining from one side (left side in Fig. 8) to the other side (right side in Fig. 8) in the left-right direction of the frame body 2 as it goes from bottom to top. The open-end inclined plate portion 833 is formed in the shape of a plate that slopes downward in the direction of movement in which the outer shoji screen 3 moves from the open position to the closed position.

[0053] The tip of the open-end inclined plate portion 833 is not connected to any component and forms the open end. The open-end inclined plate portion 833 is pushed against the upper end of the outer shoji screen 3 as the outer shoji screen 3 moves left and right. In this embodiment, the open-end inclined plate portion 833 is pushed upward from the upper end of the outer shoji screen 3 when the outer shoji screen 3 moves from the open position to the closed position. As a result, when the outer shoji screen 3 moves from the open position to the closed position, the open-end inclined plate portion 833 is pushed against the outer shoji screen 3, and the elastically deformable frame portion 83 is crushed upward with an elastic repulsive force.

[0054] In the above air leakage prevention member 8, when the outer screen 3 moves from the open position (see Figure 9) to the closed position (see Figure 8), the elastically deformable frame portion 83 is crushed upward with an elastic repulsive force as the open-end side inclined plate portion 833 is pressed by the outer screen 3. As the outer screen 3 is moved further toward the closed position, the elastically deformable frame portion 83 is moved from the open-end side inclined plate portion 833 of the elastically deformable frame portion 83 to the underside of the bottom side plate portion 832 with the elastically deformable frame portion 83 crushed.

[0055] In this way, as shown in Figure 8, the upper end of the upper anti-sway member 52 provided at the upper end of the vertical stile 33 on the door tip side of the outer shoji screen 3 abuts against the underside of the bottom side plate portion 832 of the elastically deformable frame portion 83 of the air leakage prevention member 8. As a result, the elastically deformable frame portion 83 of the air leakage prevention member 8 abuts against the hard upper anti-sway member 52 while the elastically deformable frame portion 83 has an elastic repulsive force, thereby improving airtightness.

[0056] In the second embodiment, the air leakage prevention member 8 is crushed upward with an elastic repulsive force when the open end side inclined plate portion 833 of the elastically deformable frame portion 83 is pressed against the outer screen 3. Then, with the elastically deformable frame portion 83 of the air leakage prevention member 8 having an elastic repulsive force, the upper sway stop member 52 abuts against the upper end of the vertical frame 33 of the outer screen 3. This further improves the airtightness between the upper frame 21 and the vertical frame 33 of the outer screen 3.

[0057] A third embodiment will now be described. As shown in Figures 10 and 11, the base-end inclined plate portion 931 of the elastically deformable frame portion 93 of the air leak prevention member 9 of the third embodiment has a different shape from the base-end inclined plate portion 831 of the elastically deformable frame portion 83 of the air leak prevention member 8 of the second embodiment. In the description of the third embodiment, the same components as those of the second embodiment will be assigned the same reference numerals, and the description thereof will be omitted.

[0058] As shown in FIG. 10, the air leak prevention member 9 of the third embodiment has an attachment plate portion 91, a support plate portion 92 arranged below the attachment plate portion 91, and an elastically deformable frame portion 93.

[0059] The elastically deformable frame portion 93 is formed with an open top, and its shape including the upper support plate portion 92 is formed into a parallelogram frame shape. The elastically deformable frame portion 93 has a base end side inclined plate portion 931, a bottom side plate portion 932, and an open end side inclined plate portion 933 (inclined plate portion).

[0060] The base-end inclined plate portion 931 extends obliquely downward from the support plate portion 92 in the opposite inclination direction to the base-end inclined plate portion 831 of the second embodiment. The base-end inclined plate portion 931 extends obliquely downward for a predetermined length, inclining from the other side to the one side in the left-right direction as it goes from top to bottom. The bottom side plate portion 932 and the open-end inclined plate portion 933 have the same configuration as the bottom side plate portion 832 and the open-end inclined plate portion 833 of the second embodiment.

[0061] In the above air leakage prevention member 9, when the outer screen 3 moves from the open position (see FIG. 11) to the closed position (see FIG. 10), the elastically deformable frame portion 93 is crushed upward with an elastic repulsive force as the open-end side inclined plate portion 933 is pressed by the outer screen 3. As the outer screen 3 is further moved toward the closed position, the elastically deformable frame portion 93 is moved from the open-end side inclined plate portion 933 of the elastically deformable frame portion 93 to the underside of the bottom side plate portion 932 with the elastically deformable frame portion 93 crushed.

[0062] In this way, as shown in Figure 10, the upper end of the upper anti-sway member 52 provided at the upper end of the vertical stile 33 on the door tip side of the outer shoji screen 3 abuts against the underside of the bottom side plate portion 932 of the elastically deformable frame portion 93 of the air leak prevention member 9. As a result, the elastically deformable frame portion 93 of the air leak prevention member 9 abuts against the hard upper anti-sway member 52 while the elastically deformable frame portion 93 has an elastic repulsive force, thereby improving airtightness.

[0063] As with the air leak prevention member 8 of the second embodiment, the air leak prevention member 9 of the third embodiment is crushed upward with an elastic repulsive force when the open end side inclined plate portion 933 of the elastically deformable frame portion 93 is pressed against the outer shroud 3. Then, with the elastically deformable frame portion 93 of the air leak prevention member 9 with an elastic repulsive force, the upper sway stop member 52 abuts against the upper end of the vertical frame 33 of the outer shroud 3. This further improves the airtightness between the upper frame 21 and the vertical frame 33 of the outer shroud 3.

[0064] 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.

[0065] For example, in the first embodiment, six fin portions 72 are provided on the air leakage prevention member 7, but the number of fin portions 72 is not limited to this. Two to five, or seven or more fin portions 72 may be provided. The number of sponge portions (cushion portions) is also not limited.

[0066] In the first embodiment, the air leakage prevention member 7 has the fin portion 72 and the sponge portion 73 (cushion portion), but is not limited to this. For example, the air leakage prevention member 7 may be composed of only the sponge portion 73 (cushion portion). [Explanation of symbols]
