DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples shown in the drawings.

[0010] [Outline of flood-resistant sashes] 1 is a schematic interior view of a flood-resistant sash 100 to be attached to the skeleton of a building (not shown). The flood-resistant sash 100 is attached to and installed in an opening in the skeleton of a building. In the following description, the left side of the page in Figure 1 is defined as the "left" of the floodproof sash 100, the right side as the "right," the top side as the "top," the bottom side as the "bottom," the depth direction as the "front," and the front side as the "rear." The up-down direction of the floodproof sash 100 is parallel to the vertical direction, and the front-to-back and left-to-right directions are parallel to the horizontal direction. Furthermore, the front side of the floodproof sash 100 is the exterior side, and the rear side is the interior side.

[0011] The flood-resistant sash 100 is an externally movable single sliding window sash, and has a frame body 10 and an externally movable shoji screen 8. Inside the frame body 10, on the right side of the mullion 6 described below, a fixed glass 7 fixed to the frame body 10 is held, and on the left side, the externally movable shoji screen 8 is arranged so that it can slide to the right. The externally movable shoji screen 8 is a glass shoji screen, and is arranged on the exterior side of the fixed glass 7. When the externally movable shoji screen 8 is arranged on the left side of the frame body 10, the flood-resistant sash 100 is in a closed state, and can be opened by pulling it to the right.

[0012] [Frame body] The frame body 10 has a lower frame 2 and an upper frame 3 as horizontal frames parallel to the left-right direction, a left vertical frame 4 and a right vertical frame 5 as vertical frames parallel to the up-down direction, and a post 6 parallel to the up-down direction. The bottom frame 2, top frame 3, left vertical frame 4, right vertical frame 5, and mullion 6 are frame components, all of which are made from extruded metal materials such as aluminum alloy. The cross-sectional shapes perpendicular to the direction of extension of the bottom frame 2, top frame 3, left vertical frame 4, right vertical frame 5, and mullion 6 are continuous over their entire lengths, and are shaped to suit each application by cutting out portions, drilling holes, or other processing. In addition, any or all of the lower frame 2, upper frame 3, left vertical frame 4, right vertical frame 5 and uprights 6 may be formed from resin instead of metal, provided that the required strength can be ensured.

[0013] The bottom frame 2, top frame 3, left vertical frame 4, and right vertical frame 5 are assembled in a rectangular shape. The mullions 6 are assembled in a state where they suspend the middle parts of the bottom frame 2 and top frame 3 in the left-right direction. The fixed glass 7 is held in a fixed state in the inner area surrounded by the lower frame 2, upper frame 3, right vertical frame 5 and mullion 6.

[0014] 2 is a cross-sectional view of the flood-resistant sash 100 taken along line SS in FIG. 1, FIG. 3 is a cross-sectional view taken along line TT, and FIG. 4 is a cross-sectional view taken along line UU.

[0015] [Frame body: bottom frame] The lower frame 2 extends in the left-right direction, and except for the connection portion with the upright 6, the cross-sectional shape shown in Figure 2 remains constant throughout its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The lower frame 2 holds an externally movable shoji screen 8 at its front portion and a fixed glass 7 at its rear portion.

[0016] An inclined plate 21 with a gentle downward slope is formed on the front side of the lower frame 2, and a rail 211 along which the rollers 817 (described later) of the externally movable shoji screen 8 are transferred is erected on the upper surface of the plate over almost the entire length in the left-right direction. The inclined plate 21 has the function of draining water accumulated inside the lower frame 2 to the outside.

[0017] An open structure section 22 with an open top over its entire length is arranged at the rear of the lower frame 2, at a higher position than the inclined plate 21 via a step. The open structure portion 22 has a flat bottom portion 221 that is horizontal and aligned in the left-right direction, a front portion 222 that stands upward from the front end of the bottom portion 221, a rear portion 223 that extends upward and downward from the rear end of the bottom portion 221, a top portion 225 that extends forward with a narrow width from the upper end of the rear portion 223, and a hanging portion 226 that hangs down from the front end of the top portion 225, and has an open cross-sectional shape when viewed from the left-right direction.

[0018] The left-right center of the open structure section 22 is connected with the lower end face of the mullion 6 abutting against the upper surface of the bottom surface section 221. For this reason, the top surface section 225 has a rectangular cutout 225a (see Figure 13) that is the width of the mullion 6 in the left-right direction so that the lower end of the mullion 6 can be inserted. As mentioned above, the right side of the mullion 6 in the open structure section 22 is open upward to allow the insertion and support of the lower end of the fixed glass 7. On the other hand, the left side of the mullion 6 in the open structure section 22 does not need to be open, so it is closed by the attachment of a cover member 23 as a frame member.

[0019] The cover member 23 is also an extruded metal or resin member extending in the left-right direction, and the cross-sectional shape shown in Figure 2 continues uniformly over its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The cover member 23 has a flat top surface portion 231 that is horizontal and extends in the left-right direction, and a front surface portion 232 that hangs down from the front end of the lower surface of the top surface portion 231. At the lower end of the front surface portion 232, there is provided a latched portion 233 that receives, from behind, a claw portion 222a formed by bending rearward from the upper end of the front surface portion 222 of the open structure portion 22. Furthermore, at the rear end of top surface portion 231, a crank-shaped insertion portion 234 that is one step lower than top surface portion 231 is provided over the entire length in the left-right direction. This insertion portion 234 can be inserted into insertion portion 224 that has a slit-shaped opening along the left-right direction and is provided below hanging portion 226 of open structure portion 22. Insertion portion 234 is formed with a barb that prevents it from slipping out when inserted into insertion portion 224. Therefore, the cover member 23 can be attached to the top of the open structure portion 22 while being restrained from both the front and rear directions.

[0020] The externally movable shoji screen 8, which will be described later, holds the glass 89, and the cover member 23 holds a watertight material 101 that can be pressed against the periphery of an opening 801 overlooking the glass 89 on the rear side of the externally movable shoji screen 8 when necessary. The front surface of the front surface part 232 of the cover member 23 is a surface facing a part of the periphery of the opening 801 on the rear side of the externally movable shoji screen 8. Therefore, a sheath part 235 for storing the watertight material 101, which is made up of a pair of ridges 235a protruding forward, is formed on the upper front surface of the front surface part 232. This sheath part 235 holds the watertight material 101 in a state aligned in the left-right direction. The pair of ridges 235a constituting the sheath 235 both protrude forward by the same length when viewed from the left and right, and have a shape with bent portions at their front ends that are bent in directions that face each other, as shown in Fig. 2. The pair of ridges 235a form a rectangular internal region in the left and right view of the sheath 235, and the seat of the watertight material 101 can be stored within this region, and the pressure-welding ridges protruding from the seat can be held in a state where they protrude forward from between the bent portions of the pair of ridges 235a.

[0021] As shown in Figure 4, to the right of the mullion 6 in the open structure section 22, a retaining member 24 is arranged as a frame member into which the lower end of the fixed glass 7 is inserted and which holds it from the front. This retaining member 24 is also an extruded metal or resin molding that extends in the left-right direction, and the cross-sectional shape shown in Figure 4 continues uniformly over its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The pressing member 24 has an attachment portion 241 attached to the front surface 222 of the open structure portion 22 and a pressing portion 242 connected to the upper side of the front surface 222 of the open structure portion 22. The mounting portion 241 is provided with latched portions 243 and 244 that receive the claw portion 222a provided on the front surface 222 of the open structure portion 22 and the claw portion 221a provided on the upper surface of the bottom surface portion 221 from behind. The retaining portion 242 has a rib formed on the rear side for retaining the lower end of the fixed glass 7.

[0022] The FIX glass 7 has sealing material 71 and spacers 72 provided along the outer periphery on the front and rear sides, respectively, and the lower end is clamped and held in the front-to-rear direction by the pressing portion 242 of the pressing member 24 and the top surface portion 225 and hanging portion 226 of the open structure portion 22 through these. By inserting the sealing material 71, airtightness, watertightness, and soundproofing between the fixed glass 7 and the lower frame 2 are maintained.

[0023] [Frame body: upper frame] The upper frame 3 extends in the left-right direction, and except for the connection portion with the upright 6, the cross-sectional shape shown in Figure 2 remains constant throughout its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The upper frame 3 holds an externally movable shoji screen 8 at its front portion and a fixed glass 7 at its rear portion.

[0024] A first open structure 31 that is open on the bottom side and extends over the entire length in the left-right direction is formed on the front side of the upper frame 3. The first open structure 31 has a flat top surface 311 that is horizontal and aligned in the left-right direction, a front surface 312 that hangs down from the front end of the top surface 311, and a rear surface 313 that hangs down from the rear end of the top surface 311, and has an open cross-sectional shape when viewed from the left-right direction.

[0025] The rear side of the upper frame 3 is positioned lower than the first open structure portion 31 via a step, and a second open structure portion 32 is formed whose lower side is open over its entire length. The second open structure portion 32 has a top surface portion 321 that is horizontal and aligned in the left-right direction, a front surface portion 322 that hangs down from the front end of the top surface portion 321, a rear surface portion 323 that extends upward and downward from the rear end of the top surface portion 321, a bottom surface portion 325 that extends forward with a narrow width from the lower end of the rear surface portion 323, and an upright portion 326 that stands upright from the front end of the bottom surface portion 325, and has an open cross-sectional shape when viewed from the left-right direction. In the case of the upper frame 3, the right side of the upright 6 in the second open structure 32 is also open downward to allow for insertion and support of the upper end of the fixed glass 7. In addition, the left side of the upright 6 in the second open structure 32 does not need to be open, so a cover member 33 serving as a frame member is attached and closed.

[0026] The cover member 33 is also an extruded metal or resin member extending in the left-right direction, and the cross-sectional shape shown in FIG. 2 continues uniformly over its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The cover member 33 has a flat bottom surface portion 331 that is horizontal and extends in the left-right direction, and a front surface portion 332 that stands upright from the front end of the top surface of the bottom surface portion 331. The front surface 332 has an upper end provided with a latched portion 333 that receives, from behind, a claw portion 322a formed by bending rearward from the lower end of the front surface 322 of the second open structure portion 32. Furthermore, a crank-shaped insertion portion 334 that is one step higher than the bottom portion 331 is provided at the rear end of the bottom portion 331 over the entire length in the left-right direction. This insertion portion 334 can be inserted into an insertion receiving portion 324 that has a slit-shaped opening along the left-right direction and is provided above the standing portion 326 of the second open structure portion 32. The insertion portion 334 has a barb that prevents it from slipping out when inserted into the insertion receiving portion 324. Therefore, the cover member 33 can be attached to the lower part of the second open structure portion 32 while being constrained from both the front and rear directions.

[0027] A sheath portion 335 for storing the watertight material 101, which is made up of a pair of protruding ridges 335a protruding forward, is also formed on the lower front surface of the front surface portion 332 of the cover member 33. This sheath portion 335 holds the watertight material 101 in a state aligned in the left-right direction.

[0028] As shown in Figure 4, to the right of the mullion 6 in the second open structure section 32, a retaining member 34 is arranged as a frame member into which the upper end of the fixed glass 7 is inserted and which holds it from the front. This retaining member 34 is also an extruded metal or resin molding that extends in the left-right direction, and the cross-sectional shape shown in Figure 4 continues uniformly over its entire length in the left-right direction (excluding small details such as partial cutouts and holes). The pressing member 34 has a mounting portion 341 mounted on the upper surface of the top surface portion 321 of the second open structure portion 32 , and a pressing portion 342 connected to the bottom of the front surface portion 322 of the second open structure portion 32 . The mounting portion 341 is provided with latched portions 343 and 344 that receive the claw portion 322a provided on the front surface 322 of the second open structure portion 32 and the claw portion 321a provided on the lower surface of the top surface portion 321 from behind. The retaining portion 342 has a rib formed on the rear side for retaining the lower end of the fixed glass 7.

[0029] The upper end of the fixed glass 7 is sandwiched and held in the front-to-rear direction by the pressing portion 342 of the pressing member 34 and the bottom portion 325 and upright portion 326 of the second open structure portion 32 via the sealing material 71 and spacer 72. By inserting the sealing material 71, airtightness, watertightness, and soundproofness between the fixed glass 7 and the upper frame 3 are ensured.

[0030] [Frame body: left vertical frame] The left vertical frame 4 extends in the vertical direction, and the cross-sectional shape shown in FIG. 3 continues uniformly over the entire vertical length (excluding small details such as partial cutouts and holes). The left vertical frame 4 is capable of receiving the left end of the externally movable shoji screen 8 at its front portion.

[0031] An open structure section 41 is formed on the front side of the left vertical frame 4, with the right side open along the entire vertical length, and a closed structure section 42 with a hollow structure that is rectangular when viewed from the vertical direction is formed on the rear side of the left vertical frame 4. The open structure portion 41 has a flat vertical plate portion 411 that extends in the vertical direction and a front surface portion 412 that is connected to the front end of the vertical plate portion 411 and extends to the right, and in cooperation with the front surface portion 421 of the closed structure portion 42 described later, it has an open cross-sectional shape that is open to the right when viewed from the vertical direction. The open structure portion 41 is open to the right along its entire vertical length, allowing it to accommodate the left end of the externally movable shoji screen 8.

[0032] The closing structure 42 has a front portion 421 extending to the right from the middle portion in the fore-and-aft direction of the vertical plate portion 411 of the opening structure 41, a rear portion 422 extending to the right from the rear end portion of the vertical plate portion 411, and a vertical plate portion 423 connected to the right end portion of the front portion 421 and the right end portion of the rear portion 422, and has a closed cross-sectional shape in cooperation with the vertical plate portion 411.

[0033] Since the left vertical frame 4 and the lower frame 2 are connected with the lower end of the closing structure 42 abutting against the top surface 225 of the opening structure 22 of the lower frame 2 and the lid member 23, the lower ends of the front surface 421, rear surface 422 and vertical plate portion 423 of the closing structure 42 are cut out below the height of the top surface 225 of the opening structure 22 of the lower frame 2 and the lid member 23 (see FIG. 10). In other words, the lower end of the closing structure 42 is at a height approximately equal to the height of the top surface 225 of the opening structure 22 of the lower frame 2 and the lid member 23. Similarly, the left vertical frame 4 and the upper frame 3 are connected with the upper end of the closing structure 42 abutting against the bottom surface 325 of the second opening structure 32 of the upper frame 3 and the lid member 33, so that the upper ends of the front surface 421, rear surface 422 and vertical plate portion 423 of the closing structure 42 are cut out in portions above the lower surface height of the bottom surface 325 of the second opening structure 32 of the upper frame 3 and the lid member 33. In other words, the upper end of the closing structure 42 is at a height equal to the lower surface height of the bottom surface 325 of the second opening structure 32 of the upper frame 3 and the lid member 33.

[0034] Also, a sheath 425 for storing the watertight material 101, which is made up of a pair of protruding ridges 425a protruding forward, is formed on the front right end of the front surface of the front surface 421 of the closing structure 42. This sheath 425 holds the watertight material 101 in a state aligned in the up-down direction.

[0035] [Frame body: Right vertical frame] The right vertical frame 5 extends in the vertical direction, and the cross-sectional shape shown in FIG. 3 continues uniformly over the entire vertical length (excluding small details such as partial cutouts and holes). The right vertical frame 5 is capable of receiving the right end of the externally movable shoji screen 8 at its front portion.

[0036] A first open structure 51 that is open on the right side along the entire vertical length is formed on the front side of the right vertical frame 5, and a second open structure 52 that is open on the left side along the entire vertical length is formed on the rear side of the right vertical frame 5. The second open structure 52 is open to the left and is adapted to hold the right end of the fixed glass 7 inserted therein.

[0037] The first open structure portion 51 has a flat vertical plate portion 511 that extends in the vertical direction and a front surface portion 512 that is connected to the front end of the vertical plate portion 511 and extends to the left, and in cooperation with the front surface portion 521 of the second open structure portion 52 described later, it has an open cross-sectional shape that is open to the right when viewed from the vertical direction. The first open structure portion 51 is open to the left along its entire vertical length, allowing it to receive the right end of the externally movable shoji screen 8.

[0038] The second open structure portion 52 has an open cross-sectional shape that is open to the left when viewed from the top-bottom direction, and is composed of a front portion 521 extending to the left from the middle portion in the fore-and-aft direction of the vertical plate portion 511 of the first open structure portion 51, a rear portion 522 extending to the left from the rear end portion of the vertical plate portion 511, a vertical plate portion 523 extending forward with a narrow width from the left end portion of the rear portion 522, an extension portion 524 extending to the right from the front end portion of the vertical plate portion 523, a vertical plate portion 525 extending forward with a narrow width from slightly to the right of the left end portion of the rear portion 522, and an extension portion 526 extending to the right from the front end portion of the vertical plate portion 525.

[0039] As shown in Fig. 3, the right end of the fixed glass 7 is inserted into the open left side of the second open structure 52, and a pressing member 53 is disposed as a frame member that holds it from the front. This pressing member 53 is also an extrusion molded metal or resin that extends in the vertical direction, and the cross-sectional shape shown in Fig. 3 continues uniformly over the entire vertical length (excluding small details such as partial cutouts and holes). The pressing member 53 has an attachment portion 531 attached to the front surface portion 521 of the second open structure portion 52 and a pressing portion 532 connected to the left side of the front surface portion 521. The mounting portion 531 is provided with engaging portions 533, 534 that receive from the rear the claw portion 521a provided on the front portion 521 of the second opening structure portion 52 and the claw portion 511a provided on the left surface of the vertical plate portion 511 of the first opening structure portion 51. The pressing portion 532 has a rib formed on the rear side for pressing the lower end of the fixed glass 7.

[0040] The right end of the FIX glass 7 is clamped and held in the front-to-rear direction by the pressing portion 532 of the pressing member 53 and the vertical plate portion 523 and extension portion 524 of the second open structure portion 52 via the sealing material 71 and spacer 72. By inserting the sealing material 71, airtightness, watertightness, and soundproofing between the fixed glass 7 and the right vertical frame 5 are ensured.

[0041] [Frame body: mullion] The mullion 6 extends in the vertical direction, and the cross-sectional shape shown in FIG. 3 continues uniformly over the entire vertical length (excluding small details such as partial notches and holes). The mullion 6 has a first closing structure 61 at its rear that has a hollow structure and is rectangular when viewed from above, a second closing structure 62 at its front left that also has a hollow structure and is rectangular when viewed from above, and an open structure 63 at its front right. The open structure 63 is open to the right and holds the left end of the fixed glass 7 inserted therein.

[0042] The first closing structure 61 protrudes rearward beyond the rear ends of the lower frame 2 and the upper frame 3 when viewed in the vertical direction. The first closing structure 61 has a flat rear surface 611 that is aligned in the vertical direction, a left surface 612 that extends forward from the left end of the rear surface 611, and a right surface 613 that extends forward from the right end of the rear surface 611, and the second closing structure 62 and the open structure 63 are located in front of the first closing structure 61, and the first closing structure 61 has a closed cross-sectional shape when viewed in the vertical direction. The mullion 6, with the exception of a small portion, is connected to the lower frame 2 by butting against the upper surface of the bottom surface 221 of the open structure portion 22 of the lower frame 2 from above. The first closing structure portion 61 protrudes rearward from the lower frame 2 and cannot be brought into contact with the lower frame 2, so the lower end of the first closing structure portion 61 is cut out along an inclined surface facing diagonally downward and forward, as shown by the two-dot chain line in Figure 2. Similarly, the mullion 6, with the exception of a small portion, is connected to the upper frame 3 by abutting from above against the upper surface of the top surface 321 of the second open structure portion 32 of the upper frame 3. Since the first closing structure portion 61 protrudes rearward from the upper frame 3 and cannot be abutted against the upper frame 3, the first closing structure portion 61 has its upper end cut out along an inclined surface facing diagonally upward and forward, as shown by the two-dot chain line in Figure 2.

[0043] The second closing structure part 62 is positioned facing forward and opposite the externally movable shoji screen 8, and has a flat front surface part 621 that extends vertically, a left surface part 622 that extends rearward from the left end of the front surface part 621, and a rear surface part 623 that extends rightward from the rear end of the left surface part 622, and has a closed cross-sectional shape in cooperation with the left surface part 632 of the opening structure part 63 described below. The rear end of the left surface portion 622 is integrally connected to the front end of the left surface portion 612 of the first closure structure portion 61 so as to be flush with the front end of the left surface portion 612 .

[0044] In addition, the lower ends of the front surface 621 and left surface 622 of the second closing structure 62 are abutted from above against the bottom surface 221 of the opening structure 22 of the lower frame 2, connecting the upright 6 and the lower frame 2. In addition, the upper ends of the front surface 621 and left surface 622 of the second closing structure 62 are abutted from above against the top surface 321 of the second opening structure 32 of the upper frame 3, connecting the upright 6 and the upper frame 3.

[0045] Also, a sheath portion 625 for storing the watertight material 101, which is made up of a pair of protruding ridges 625a protruding forward, is formed on the left end of the front surface of the front surface portion 621 of the second closure structure portion 62. This sheath portion 625 holds the watertight material 101 in a state aligned in the up-down direction.

[0046] The open structure portion 63 has an open cross-sectional shape that is open to the right when viewed from the top-bottom direction, and is made up of a rear surface portion 623 of the second closing structure portion 62, a left surface portion 632 that extends forward from the middle portion of the rear surface portion 623 in the left-right direction, and a front surface portion 633 that extends to the right with a narrow width from the front end portion of the left surface portion 632.

[0047] As shown in Fig. 3, the left end of the fixed glass 7 is inserted into the open right side of the open structure 63, and a pressing member 64 is arranged as a frame member that holds it from the front. This pressing member 64 is also an extrusion molded metal or resin that extends in the vertical direction, and the cross-sectional shape shown in Fig. 3 continues uniformly over its entire length in the vertical direction (excluding small details such as partial cutouts and holes). The pressing member 64 has an attachment portion 641 attached to the front surface 633 of the open structure portion 63 , and a pressing portion 642 connected to the right side of the front surface 633 . The mounting portion 641 is provided with latching portions 643, 644 that receive from behind a claw portion 633a provided on the front surface 633 of the open structure portion 63 and a claw portion 632a provided on the right surface of the left surface portion 632 of the open structure portion 63. The retaining portion 642 has a rib formed on the rear side for retaining the left end of the fixed glass 7.

[0048] The left end of the fixed glass 7 is sandwiched and held in the front-rear direction between the pressing portion 642 and the rear surface portion 623 of the pressing member 64 via the sealing material 71 and the spacer 72 . By inserting the sealing material 71, airtightness, watertightness, and sound insulation between the fixed glass 7 and the mullion 6 are ensured. As a result, the entire outer edge of the FIX glass 7 is held in place by the lower frame 2, upper frame 3, right vertical frame 5 and upright 6 via sealing material 71 and spacer 72, ensuring airtightness, watertightness and soundproofing between the FIX glass 7 and the frame body 10.

[0049] The mullion 6 and the lower frame 2 are connected with the lower end of the rear surface 623 of the second closure structure 62 abutting against the upper surface of the inserted portion 224. In other words, the lower end of the rear surface 623 is at a height approximately equal to the height of the upper surface of the inserted portion 224. Furthermore, the left side portion 622, front side portion 621, open structure portion 63 and lower end portion of the pressing member 64 of the second closing structure portion 62 are abutted against the bottom surface portion 221 of the open structure portion 22 of the lower frame 2, and the upright 6 and lower frame 2 are connected in this state. In other words, the left side portion 622, front side portion 621, open structure portion 63 and lower end portion of the pressing member 64 of the second closing structure portion 62 are at a height approximately equal to the height of the upper surface of the bottom surface portion 221 of the open structure portion 22 of the lower frame 2.

[0050] [External sliding screen] The externally movable shoji screen 8 is assembled into a frame shape by a lower frame 81 and an upper frame 83 extending in the left-right direction, and a left vertical frame 85 and a right vertical frame 87 extending in the up-down direction, and holds glass 89 inside. The bottom frame 81, the top frame 83, the left vertical frame 85, and the right vertical frame 87 are all made of extruded metal material, such as aluminum alloy. The cross-sectional shape perpendicular to the direction of extension of the bottom frame 81, the top frame 83, the left vertical frame 85, and the right vertical frame 87 is continuous over their entire length, and is formed into a shape appropriate for each use by processing such as cutting out parts or drilling holes. It should be noted that any or all of the lower frame 81, upper frame 83, left vertical frame 85 and right vertical frame 87 may be formed from resin instead of metal, provided that the required strength can be ensured.

[0051] [External sliding screen: left vertical frame] The left vertical frame 85 extends in the vertical direction, and the cross-sectional shape shown in FIG. 3 continues uniformly over the entire vertical length (excluding small details such as partial cutouts and holes). The left vertical frame 85 has a flat left surface portion 851 that extends in the vertical direction, a front surface portion 852 that extends to the right from the front end of the left surface portion 851, a rear surface portion 853 that extends to the right from the rear end of the left surface portion 851, a right surface portion 854 that extends forward a short distance from the right end of the rear surface portion 853, an abutment piece 855 that extends to the left a short distance from the front end of the right surface portion 854, and a partition portion 856 that spans between the left-right middle portion of the front surface portion 852 and the left-right middle portion of the rear surface portion 853. The left surface portion 851, the left portion of the front surface portion 852, the left portion of the rear surface portion 853, and the partition portion 856 form a hollow structure (closed cross-sectional shape) that is rectangular when viewed from the top and bottom, and the right portion of the front surface portion 852, the right portion of the rear surface portion 853, and the partition portion 856 form an open structure (open cross-sectional shape) that is open to the right.

[0052] The front surface 852, rear surface 853, and partition wall 856, which form an open structure open to the right side, form a glass groove into which the left end of the glass 89 is inserted, as shown in FIG. The left end of the glass 89 is sandwiched and held in the front-rear direction between the rear surface of the right end of the front surface portion 852 and the front surface of the abutting piece 855 via a sealant 891 and a spacer 892 . By inserting the sealant 891, airtightness, watertightness, and sound insulation between the glass 89 and the left vertical frame 85 are ensured.

[0053] [External sliding screen: right vertical frame] The right vertical frame 87 extends in the vertical direction, and the cross-sectional shape shown in FIG. 3 continues uniformly over the entire vertical length (excluding small details such as partial cutouts and holes). The right vertical frame 87 has a flat right side portion 871 that extends in the vertical direction, a front side portion 872 that extends to the left from the front end of the right side portion 871, a rear side portion 873 that extends to the left from the rear end of the right side portion 871, a left side portion 874 that extends forward a short distance from the left end of the rear side portion 873, a contact piece 875 that extends rightward a short distance from the front end of the left side portion 874, and a partition portion 876 that spans between slightly to the left of the left-right middle portion of the front side portion 872 and slightly to the left of the left-right middle portion of the rear side portion 873. The right surface portion 871, the right portion of the front surface portion 872, the right portion of the rear surface portion 873, and the partition portion 876 form a hollow structure (closed cross-sectional shape) that is rectangular when viewed from the top and bottom, and the left portion of the front surface portion 872, the left portion of the rear surface portion 873, and the partition portion 876 form an open structure (open cross-sectional shape) that is open to the left. The width in the left-right direction of the hollow structure (closed cross-sectional shape) of the right vertical frame 87 is set to be somewhat wider than the width in the left-right direction of the hollow structure (closed cross-sectional shape) of the left vertical frame 85 described above.

[0054] The front surface 872, rear surface 873, and partition wall 876, which form an open structure open to the left, form a glass groove into which the right end of the glass 89 is inserted, as shown in FIG. The right end of the glass 89 is sandwiched and held in the front-rear direction between the rear surface of the left end of the front surface portion 872 and the front surface of the abutting piece 875 via a sealant 891 and a spacer 892 . By inserting the sealant 891, airtightness, watertightness, and sound insulation between the glass 89 and the right vertical frame 87 are ensured.

[0055] [External sliding screen: lower frame] The lower frame 81 extends in the left-right direction, and the cross-sectional shape shown in FIG. 2 continues uniformly over the entire length in the left-right direction (excluding small details such as partial cutouts and holes). The lower frame 81 has a flat bottom portion 811 that extends in the left-right direction, a front portion 812 that extends upward and downward from the front end of the bottom portion 811, a rear portion 813 that extends upward and downward from the rear end of the bottom portion 811, a top portion 814 that extends forward a short distance from the upper end of the rear portion 813, a contact piece 815 that extends downward an even shorter distance from the front end of the top portion 814, and a partition portion 816 that spans between the lower portion of the front portion 812 and the lower portion of the rear portion 813. The lower part of the front surface part 812 is retracted one step backward, and the lower part of the rear surface part 813 is also retracted one step forward.

[0056] The bottom portion 811, the upper portion of the front portion 812, and the upper portion of the rear portion 813 form an open structure (open cross-sectional shape) that is open upward, the middle portion of the bottom portion 811, the front portion 812, the middle portion of the rear portion 813, and the partition portion 816 form a hollow structure (closed cross-sectional shape) that is rectangular when viewed from the left and right, and the partition portion 816, the lower portion of the front portion 812, and the lower portion of the rear portion 813 form an open structure (open cross-sectional shape) that is open downward.

[0057] The bottom surface portion 811, the front surface portion 812, and the rear surface portion 813, which form an open structure that is open upward, form a glass groove into which the lower end of the glass 89 is inserted, as shown in FIG. The glass 89 is held in place by having its lower end sandwiched between the rear surface of the upper end of the front surface portion 812 and the front surface of the abutting piece 815 in the front-rear direction via a sealant 891 and a spacer 892 . By inserting the sealant 891, airtightness, watertightness, and sound insulation between the glass 89 and the right vertical frame 87 are ensured.

[0058] Furthermore, a door roller 817 and its retaining frame 818 are provided at the left and right ends of the underside of the bottom surface 811. As mentioned above, each door roller 817 can move on the rails 211 provided on the lower frame 2 of the frame body 10, allowing the entire externally movable shoji screen 8 to slide left and right.

[0059] In addition, drain holes that penetrate vertically are formed in the bottom surface portion 811 and the partition wall portion 816. Furthermore, an opening is formed in the partition wall portion 816 to avoid interference with the door roller 817 and the holding frame 818.

[0060] [External sliding screen: upper frame] The upper frame 83 extends in the left-right direction, and the cross-sectional shape shown in FIG. 2 continues uniformly over the entire length in the left-right direction (excluding small details such as partial notches and holes). The upper frame 83 has a top surface portion 831 that extends in the left-right direction, a front surface portion 832 that extends upward and downward from the front end of the top surface portion 831, a rear surface portion 833 that extends downward from the rear end of the top surface portion 831, a bottom surface portion 834 that extends forward a short distance from the lower end of the rear surface portion 833, and a partition portion 835 that extends upward from the front end of the bottom surface portion 834 to the top surface portion 831. The upper part of the front surface part 832 is retracted one step backward, and the upper part of the rear surface part 833 is also retracted one step forward.

[0061] The top surface 831, the lower part of the front surface 832, and the partition wall 835 form an open structure (open cross-sectional shape) that is open downward, and the top surface 831, the rear surface 833, the bottom surface 834, and the partition wall 835 form a closed cross-sectional shape from the left and right directions.

[0062] The top surface portion 831, the front surface portion 832, and the partition wall portion 835, which are open downward, form a glass groove into which the upper end of the glass 89 is inserted, as shown in FIG. The glass 89 is held in place by having its upper end sandwiched between the lower rear surface of the front surface portion 832 and the front surface of the partition wall portion 835 in the front-rear direction via a sealant 891 and a spacer 892 . By inserting the sealing material 891, airtightness, watertightness, and soundproofness between the glass 89 and the upper frame 83 are ensured. As a result, the entire outer edge of the glass 89 is held in place by the lower frame 81, upper frame 83, left vertical frame 85, and right vertical frame 87 via sealing material 891 and spacer 892, ensuring airtightness, watertightness, and soundproofing between the glass 89 and the externally movable shoji screen 8.

[0063] [Pull handle] As shown in Figures 1 and 3, a pull handle 102 is provided between the frame body 10 and the externally movable shoji screen 8 to make the space between them airtight, watertight and soundproof. The pull-up handle 102 is provided on the right surface of the right surface portion 854 of the left vertical frame 85 of the externally movable shoji screen 8 and on the left surface of the left surface portion 874 of the right vertical frame 87. This pull handle 102 cooperates with a receiving bracket 103 provided on the frame body 10 to pull the frame body 10 and the externally movable shoji screen 8 relatively forward and backward. The receiving bracket 103 is provided on the right surface of the vertical plate portion 423 of the left vertical frame 4 of the frame body 10 and on the left surface of the left surface portion 622 of the mullion 6.

[0064] The pulling handle 102 is supported by a rotation shaft that runs in the left-right direction, and can be rotated so that the handle tip is pulled backward from an upward-facing state. A cam groove is formed on the center side of the rotation radius of the pulling handle 102, and by the above-mentioned rotation operation, the cam groove can receive the pin that extends in the left-right direction of the receiving metal fitting 103. When the pulling handle 102 is rotated backward by the rotation operation, the cam groove is shaped to pull the pin of the receiving metal fitting 103 toward the rotation center. Therefore, by rotating the pull-in handle 102 rearward, the frame body 10 and the externally movable shoji screen 8 can be moved closer to each other in the front-to-rear direction. As a result, the tip of the watertight material 101 is pressed against the area surrounding the entire periphery of the opening 801 of the externally movable shoji screen 8, and the frame body 10 and the externally movable shoji screen 8 are connected while ensuring airtightness, watertightness, and soundproofing on the indoor side of the glass 89 of the externally movable shoji screen 8 through the opening 801. Although the example has been given in which two units of the pull-in handle 102 and the receiving bracket 103 are provided, the number of units may be one, or three or more.

[0065] [Sealing structure of mold material (1)] The water-resistant sash 100 has a structure in which the frame body 10 and the externally movable shoji screen 8 are both assembled by connecting multiple moldings, so the harder the material, the more difficult it is to maintain sufficient watertightness unless special treatment is applied between the moldings, and the water-resistant properties decrease. For this reason, the flood-resistant sash 100 has a molded sealing structure attached to each part of the frame body 10 and the externally movable shoji screen 8.

[0066] As one aspect of the seal structure of the mold material, a seal structure (1) of the mold material that is installed at the connection point between the lower frame 2 and the left vertical frame 4 of the frame body 10, in the region R1 shown in Figure 3, will be described based on Figures 5 to 11. Figure 5 is an oblique view of the connection point between the lower frame 2 and the left vertical frame 4 of the frame body 10 after the molding seal structure (1) has been installed; Figure 6 is an oblique view showing the seal structure between the lower frame 2 and the left vertical frame 4 other than the seal structure (1); Figure 7 is an oblique view of the lower end of the left vertical frame 4 in the preparation stage before the seal structure (1) is installed; Figure 8 is an oblique view of the seal material receiving member 110 shown in Figure 7; Figure 9 is an oblique view showing the state in which seal material has been filled in a portion of the state shown in Figure 7; Figure 10 is an oblique view showing the state in which the left vertical frame 4 of Figure 9 has been assembled to the lower frame 2; and Figure 11 is an oblique view of the same configuration as Figure 10, viewed from a different direction.

[0067] The region R1 to which the seal structure (1) of the mold material is applied is a portion that satisfies the following conditions. (i) Between two connected frame members, the two opposing surfaces facing each other at the position facing the interior space are sealed with a fillable sealant. (ii) The two opposing surfaces are located in a range that is closer to the room than the watertight material 101. (iii) Between the two connected frame members, a fillable sealant is filled into the gap between the two opposing surfaces. Note that conditions (i), (ii), and (iii) are examples and are not intended to limit the scope of the present invention. The sealing structure (1) may be installed at any location where water may enter the interior of the water-resistant sash 100.

[0068] The "two opposing surfaces facing each other at a position facing the indoor space" in the above condition (i) refers to the two opposing surfaces located in front of (just before) the indoor space (at the position closest to the indoor space) within the flood-resistant sash 100 on the path of flooding from the outside to the inside of the room, assuming that the externally movable shoji screen 8 is tightly and watertightly attached to the frame body 10 by the aforementioned pulling handle 102 (hereinafter simply referred to as the "watertight state of the externally movable shoji screen 8"). In the case of the lower frame 2 and the left vertical frame 4, the three pairs of opposing surfaces that correspond to these two surfaces are the lower end surface of the front surface 421 and the upper surface of the top surface 231, the lower end surface of the rear surface 422 and the upper surface of the top surface 225, and the lower end surface of the vertical plate 423 and the upper surfaces of the top surfaces 225 and 231.

[0069] Furthermore, the "two opposing surfaces facing each other within the range of the watertight material 101" in condition (ii) refers to two opposing surfaces that are downstream of the watertight material 101 in the water-logging path from the outside to the inside of the room within the flood-resistant sash 100. In other words, these are two opposing surfaces that are in a position where water can enter the room through the frame body 10 even when the external moving shoji screen 8 is watertight using the watertight material 101. In the case of the lower frame 2 and the left vertical frame 4, specifically, the three pairs of opposing surfaces exemplified in condition (i) are the lower end surface of the front portion 421 and the upper surface of the top surface 231, and the range excluding the area to the left of the range through which the watertight material 101 passes (in Figure 9, part of the lower end surface of the front portion 421 has been cut away to make it higher, but the part that has not been cut away is excluded from the target of (ii)).

[0070] The "gap" in condition (iii) refers to a gap that is formed by actively separating the gap to the minimum width that allows the sealing material S to be filled so that it adheres to both opposing surfaces that satisfy (i) and (ii). The minimum width does not mean a width that is so narrow that, when the sealing material S is filled from the outside of the gap, the sealing material S does not enter the gap sufficiently to maintain watertightness. In the case of the lower frame 2 and the left vertical frame 4, for example, of the entire lower end surface of the closure structure 42, at least the left half of the lower end surface of the front surface 421 is lowered by one step, as shown in Fig. 9. This lowered area is in close contact with the upper surface of the top surface 225 of the lower frame 2 so as not to create a gap, but the remaining areas, i.e., the right end of the lower end surface of the front surface 421, the entire lower end surface of the rear surface 422, and the entire lower end surface of the vertical plate 423, face the upper surface of the top surface 225 of the lower frame 2 or the upper surface of the top surface 231 of the lid member 23, with a gap N1 (see Fig. 10) formed. Sealant S is filled into the area where this gap N1 is formed.

[0071] The sealant S used in the flood-resistant sash 100 is, for example, a silicone-based sealant such as silicone sealant (product name "Cemedine 8060"). However, the sealant S is not limited to the above, as long as it is a paste-like material that can be filled and is watertight. Furthermore, the sealant S may be one that hardens after being filled, but it is preferable that it shrinks little or does not shrink at all after hardening.

[0072] Next, the construction order and details of the seal structure (1) of the mold material will be explained. 6 shows a sealing structure other than sealing structure (1) applied between the bottom frame 2 and the left vertical frame 4. That is, the bottom frame 2 and the left vertical frame 4 are connected by fastening members such as screws, bolts, and the like so that the left end faces of the bottom frame 2 and the cover member 23 and the right face of the vertical plate portion 411 of the left vertical frame 4 are pressed against each other in the left-right direction. A sheet-like sealing material 120 such as a mat sealer is inserted between the left end face of the bottom frame 2 and the right face of the vertical plate portion 411 of the left vertical frame 4. In other words, the seal structure (1) of the mold is provided on the premise that watertightness is already ensured between the left end face of the lower frame 2 and the right face of the vertical plate portion 411 of the left vertical frame 4. The same applies to the other seal structures (2) to (4) described below.

[0073] When constructing the sealing structure (1), first, as shown in Figure 7, the sealant receiving member 110 is inserted and attached inside the bottom of the closing structure portion 42 of the left vertical frame 4. The sealant receiving member 110 forms a filling space F for the sealant S on the internal space side of the closing structure portion 42 relative to the gap N1 between the two opposing surfaces, that is, the bottom surface of the closing structure portion 42 and the top surfaces of the top surface 225 of the lower frame 2 and the top surface 231 of the cover member 23. In other words, because the sealant S is in the form of a fillable paste, the sealant receiving member 110 functions as a spacer that can support the sealant S from behind to hold it in place. The material of the sealant receiving member 110 may be any material that can secure the function of holding the sealant S in a fixed position. The sealant receiving member 110 may be made of a hard material, but here, an elastic and deformable material such as foamed polyethylene (sponge) is exemplified.

[0074] As shown in FIG. 8, the sealant receiving member 110 is a low columnar body having the same height as the shape of the hollow interior of the closing structure 42 when viewed from above and below, and has a smooth bottom surface 111. 7, the sealant receiving member 110 is attached to the inside lower part of the closure structure 42 at a height that allows the bottom surface 111 to be in close contact with the top surface 225 of the lower frame 2 and the upper surface of the top surface 231 of the lid member 23. The sealant receiving member 110 may be fixed to the closure structure 42 by adhesion or the like.

[0075] The bottom surface 111 of the sealant receiving member 110 is formed with a protruding ridge 112 that fits into a recessed groove 201 (see FIG. 10) formed between the top surface 225 of the lower frame 2 and the top surface 231 of the cover member 23. Furthermore, on the bottom surface 111 of the sealing material receiving member 110, portions adjacent to the right end of the lower end surface of the front surface 421 of the blocking structure portion 42, the lower end surface of the rear surface portion 422, and the lower end surface of the vertical plate portion 423 are cut out from the bottom surface 111 upward, and this cut-out portion 113 cooperates with the front surface 421, rear surface portion 422, and vertical plate portion 423 of the blocking structure portion 42 to form a filling space F that is roughly hook-shaped and groove-like when viewed from below.

[0076] As shown in FIG. 9, the sealing material S is filled into the filling space F formed by the sealant receiving member 110 up to a height approximately equal to the lower end faces of the rear surface portion 422 and the vertical plate portion 423.

[0077] 10 and 11, the left vertical frame 4 and the lower frame 2 are connected with fastening members while the sheet-like sealing material 120 described above is inserted between them. At this time, the portion (uncut portion) of the lower end surface of the front surface 421 of the closure structure 42 excluding the right end portion thereof and the bottom surface 111 of the sealant receiving member 110 are brought into contact with the top surface 225 of the lower frame 2 and the upper surface of the top surface 231 of the cover member 23. In addition, the protruding ridge portion 112 on the bottom surface 111 of the sealant receiving member 110 is inserted into the recessed groove 201 of the lower frame 2. This forms a gap N1 between the right end of the lower end surface of the front portion 421 of the closing structure portion 42 of the left vertical frame 4, the lower end surface of the rear portion 422, and the lower end surface of the vertical plate portion 423 and the top surface portion 225 of the lower frame 2 or the upper surface of the top surface portion 231 of the cover member 23.

[0078] 5, the gap N1 is filled with the sealant S from the outside of the closing structure 42. In this case, the sealant S is also filled in the unfilled lower region of the filling space F formed by the sealant receiving member 110. This ensures water resistance between the left vertical frame 4 and the bottom frame 2.

[0079] Before the gap N1 is filled with the sealant S, the region R2 shown in Fig. 3 is filled with the sealant S. Region R2 is the interior of the recessed groove 201 formed between the top surface 225 of the lower frame 2 and the top surface 231 of the lid member 23, excluding the portion below the closure structure 42. Since the cover member 23 is also a part of the frame member that constitutes the frame body 10, the region R2 also satisfies the above-mentioned conditions (i) to (iii). That is, the groove 201 in region R2 has two opposing surfaces (the front and rear surfaces inside the groove 201) that face each other at a position facing the indoor space between the two connected frame members, the lower frame 2 and the cover member 23 (condition (i)). The recessed groove 201 in the region R2 is provided in a range closer to the room side than the watertight material 101 (condition (ii)). Furthermore, in the recessed groove 201 in the region R2, a gap is formed between the inner front and rear surfaces of the recessed groove 201 that face each other, with a width that allows filling (condition (iii)).

[0080] The portion of the recessed groove 201 below the closing structure 42 is not included in the range that is on the indoor side of the watertight material 101, and is therefore excluded from the area to be filled with the sealing material S. In areas other than those described above, a sealant receiving member 121 is inserted in advance into the inner bottom of the groove 201, as shown in Figures 11 and 12. This sealant receiving member 121 is preferably made of a material that has releasability with respect to the sealant S and a material that has shrinkage and deformation properties. Here, the same foamed polyethylene as the above-mentioned sealant receiving member 110 is used as an example of the material for the sealant receiving member 121. Then, as shown in Figure 5, the sealant S is filled into the groove 201 on top of the sealant receiving member 121. This ensures water resistance between the cover member 23 and the lower frame 2.

[0081] The groove 201 in region R2 has three inner surfaces, a bottom surface, a front surface, and a rear surface, when viewed from the left and right. If the sealant S were filled into the groove 201 without inserting the sealant receiving member 121, a so-called three-sided adhesion state would occur, which could cause the sealant S to peel off or crack due to vibration or deflection of the flood-resistant sash 100. However, by inserting the sealant receiving member 121 into the groove 201, the sealant S is in two-sided contact with the front and rear surfaces of the groove 201, which makes it possible to prevent the sealant S from peeling off or cracking. The above-described sealant receiving member 110 may be made of the same material as the sealant receiving member 121 and may have the same function.

[0082] [Sealing structure of mold material (2)] As one aspect of the sealing structure of the mold, we will explain the sealing structure (2) of the mold that is installed in the connecting point between the lower frame 2 of the frame body 10 and the upright 6, area R3 shown in Figure 3, based on Figures 12 to 17. Figure 12 is an oblique view of the connection point between the lower frame 2 and the upright 6 of the frame body 10 after the molding sealing structure (2) has been installed; Figure 13 is an oblique view of the lower frame 2 in the preparation stage before the sealing structure (2) is installed; Figure 14 is an oblique view of the same configuration as Figure 13, seen from a different direction; Figure 15 is an oblique view of the cover member 23 before being assembled to the lower frame 2; Figure 16 is an oblique view of the right end of the cover member 23 in Figure 15 with sealing material S filled; and Figure 17 is an oblique view showing the state in which the lower end of the upright 6 has been connected to the lower frame 2.

[0083] The region R3 to which the seal structure (2) of the mold material is applied satisfies the above-mentioned conditions (i) to (iii). That is, between the two connected frame members, the lower frame 2 and the mullion 6, the fillable sealant S is filled into two opposing surfaces that face each other at a position facing the indoor space (condition (i)). The two opposing surfaces include three pairs of surfaces: the left surface of the left surface portion 622 of the mullion 6 and the right-facing end surface of the cutout 225a of the top surface portion 225 of the lower frame 2, and the right end surface of the top surface portion 231; the rear surface of the rear surface portion 623 of the mullion 6 and the forward-facing end surface of the cutout 225a of the top surface portion 225 of the lower frame 2; and the right end surface of the rear surface portion 623 of the mullion 6 and the left-facing end surface of the cutout 225a of the top surface portion 225 of the lower frame 2.

[0084] All of the above-mentioned three pairs of opposing surfaces are located closer to the room than the watertight material 101 (condition (ii)). The three pairs of opposing surfaces described above are all spaced apart so as to form a gap N2 (see FIG. 17) (condition (iii)).

[0085] Next, the construction order and details of the seal structure (2) of the mold material will be explained. When constructing the seal structure (2), first, as shown in Fig. 13, the seal material receiving member 130 is attached around the cutout portion 225a between the top surface portion 225 of the lower frame 2 and the inserted portion 224. The seal material receiving member 130 may be fixed to the lower frame 2 by adhesive or the like.

[0086] The sealing material receiving member 130 has an approximately rectangular parallelepiped shape surrounded by a rear surface portion 223, a top surface portion 225, a hanging portion 226, and an inserted portion 224, and its upper portion has a recess 131 formed therein that has the same shape as the cutout 225a when viewed from above, and its lower portion has a recess 132 formed therein that has three inner surfaces that abut against the left surface of the left surface portion 622 of the upright 6, the rear surface of the rear surface portion 623, and the right end surface of the rear surface portion 623. The right-facing inner surface of the upper recess 131 is flush with and connected to the right-facing end face of the cutout 225a, the front-facing inner surface is flush with and connected to the front-facing end face of the cutout 225a, and the left-facing inner surface is flush with and connected to the left-facing end face of the cutout 225a. These inner surfaces of the recess 131 face the left surface of the left surface 622 of the mullion 6, the rear surface of the rear surface 623, and the right end face of the rear surface 623, with a certain gap N2 between them. The material of the sealant receiving member 130 is the same as that of the sealant receiving member 110 described above.

[0087] Furthermore, a sealant receiving member 140 is also attached to the right end of the cover member 23, below the top surface portion 231. The sealant receiving member 140 may be fixed to the cover member 23 by adhesive or the like. As shown in Figure 15, the sealing material receiving member 140 is a columnar body with a cross-sectional shape that extends in the left-right direction and fits into the top surface portion 231, the front surface portion 232, and the inserted portion 224, and its upper stage portion 141 abuts against the underside of the top surface portion 231, the rear surface of the front surface portion 232, and the front surface of the inserted portion 224, while its lower stage portion 142 abuts against the rear surface of the front surface portion 232 and the front surface of the inserted portion 224.

[0088] The right end of the cover member 23 is such that the lower part of the right end face of the front surface 232 abuts against the left surface of the left surface 622 of the mullion 6. In addition, the upper part of the right end face of the front surface 232, the right end face of the top surface 231, and the right end face of the insertion portion 234 are cut out to the left of the lower part of the right end face of the front surface 232 by the same width as the gap N2 and are set back to the left. As a result, when the lower frame 2 with the cover member 23 attached is connected to the mullion 6, the upper part of the right end face of the front surface 232 of the cover member 23, the right end face of the top surface 231, and the right end face of the insertion portion 234 face the left surface of the left surface 622 of the mullion 6 across the certain gap N2.

[0089] The sealant receiving member 140 is attached to the cover member 23 so that the right end surface of the lower stage 142 of the sealant receiving member 140 is flush with and connected to the lower part of the right end surface of the front surface 232, and in this state, the right end surface of the upper stage 141 of the sealant receiving member 140 is set back slightly to the left from the right end surface of the top surface 231. As a result, a filling space for the sealant S is formed below the top surface 231. The material of the sealant receiving member 140 is the same as that of the sealant receiving member 110 described above. Before the cover member 23 is attached to the lower frame 2, the sealant receiving member 140 is attached, and as shown in FIG. 16, the sealant S is filled into the above-mentioned filling area to the extent that it reaches the right end surface of the top surface portion 231.

[0090] 13 and 14, the cover member 23 is attached to the lower frame 2. It is preferable that the filling of the sealing material S into the aforementioned region R2 (groove 201) is carried out as part of a series of operations after the cover member 23 is attached to the lower frame 2 and the mullions 6 are attached to the lower frame 2. 17, the mullion 6 is attached to the lower frame 2. In this state, three pairs of opposing surfaces face each other across gaps N2: the left surface of the left surface portion 622 of the mullion 6 and the right-facing end surface of the notch 225a in the top surface portion 225 of the lower frame 2, the rear surface of the rear surface portion 623 of the mullion 6 and the front-facing end surface of the notch 225a in the top surface portion 225 of the lower frame 2, and the right end surface of the rear surface portion 623 of the mullion 6 and the left-facing end surface of the notch 225a in the top surface portion 225 of the lower frame 2. The sealant receiving member 130 also forms a sealing material filling space directly below these three pairs of opposing surfaces, with a depth equal to the height of the upper part of the sealant receiving member 130 and a groove width equal to that of the gap N2.

[0091] Furthermore, the upper part of the right end surface of the front surface 232 of the cover member 23, the right end surface of the top surface 231, and the right end surface of the insertion portion 234 face the left surface of the left surface portion 622 of the mullion 6 via a gap N2. In addition, the sealant receiving member 140 forms a sealant filling space directly below the left surface of the left surface portion 622 of the upright 6 and the right end surface of the top surface portion 231 of the cover member 23, with a depth equal to the height of the upper portion 141 of the sealant receiving member 140 and a groove width the same as the gap N2.

[0092] 12, the gaps N2 and the filling regions are filled with the sealant S from above. In this case, the sealant S is also filled into the unfilled lower region of the filling space F formed by the sealant receiving member 110. This ensures water resistance between the mullions 6 and the bottom frame 2.

[0093] [Sealing structure of mold material (3)] As one aspect of the sealing structure of the mold material, the sealing structure (3) of the mold material that is installed at the connection point between the lower frame 2 of the frame body 10 and the right vertical frame 5, region R4 shown in Figure 3, will be described based on Figures 18 and 19. Figure 18 is an oblique view of the connection point between the lower frame 2 and the right vertical frame 5 of the frame body 10 in the preparation stage for the construction of the mold seal structure (3), and Figure 19 is an oblique view of the connection point between the lower frame 2 and the right vertical frame 5 of the frame body 10 after the mold seal structure (3) has been constructed.

[0094] The region R4 to which the seal structure (3) of the mold material is applied satisfies the conditions (iia) and (iiia) instead of (ii) and (iii) among the above-mentioned conditions (i) to (iii). (i) Between two connected frame members, the two opposing surfaces facing each other at the position facing the interior space are sealed with a fillable sealant. (iia) The two opposing surfaces are located on the interior side of the glass, beyond the sealing material on the periphery. (iiia) Between two connected frame members, the space between the two opposing surfaces is sealed from the inside of the frame members with a fillable sealant. Note that conditions (i), (iia), and (iiia) are examples and are not intended to limit the scope of the present invention. The sealing structure (2) may be installed at any location where flood-resistant sash 100 may allow water to enter the interior of the room.

[0095] Between the two connected frame members, the lower frame 2 and the right vertical frame 5, the two opposing surfaces facing each other at a position facing the indoor space are the upper surface of the top surface portion 225 of the lower frame 2 and the lower end surfaces of the rear surface portion 522 and vertical plate portion 523 of the right vertical frame 5 (condition (i)). The opposing surface is located on the interior side of the fixed glass 7 relative to the sealing material 71 (condition (iia)). The opposing surfaces are sealed with a sealing material S from the front side of the rear surface portion 522 of the right vertical frame 5 (the inside of the right vertical frame 5) (condition (iiia)).

[0096] Next, the construction order and details of the seal structure (3) of the mold material will be explained. The lower frame 2 and the right vertical frame 5 are connected by fastening members such as screws, bolts, and the like so that the right end face of the lower frame 2 and the left face of the vertical plate portion 511 of the right vertical frame 5 are pressed against each other in the left-right direction. A sheet-like sealing material 122 such as a mat sealer is inserted between the right end face of the lower frame 2 and the left face of the vertical plate portion 511 of the right vertical frame 5. In other words, the seal structure (4) of the mold is set on the premise that watertightness is already ensured between the right end face of the lower frame 2 and the left face of the vertical plate portion 511 of the right vertical frame 5.

[0097] When the lower frame 2 and the right vertical frame 5 are connected, the lower end surface of the vertical plate portion 523 of the right vertical frame 5 abuts against the upper surface of the top surface portion 225 of the lower frame 2, and the lower end surfaces of the vertical plate portion 525 and the extension portions 524, 526 of the right vertical frame 5 are all spaced an equal distance from the upper surface of the top surface portion 225. The sealant receiving member 123 is positioned so that its upper surface abuts against the lower end surfaces of the vertical plate portion 525 and the extension portions 524, 526 of the right vertical frame 5. The sealant receiving member 123 abuts against the left surface of the vertical plate portion 511 of the right vertical frame 5, the front surface of the rear surface portion 522, and the right surface of the vertical plate portion 523, and is a rectangular parallelepiped whose front surface is flush with the front surfaces of the extension portions 524, 526. The thickness of the sealant receiving member 123 in the vertical direction is the thickness obtained by subtracting the width of the gap N3 from the distance between the lower end surfaces of the vertical plate portion 525 and the extension portions 524, 526 of the right vertical frame 5 and the upper surface of the top surface portion 225. The width of the gap N3 is not particularly limited, but is set to a width that allows the sealant S to be thoroughly filled from the front into the filling area below the sealant receiving member 123. If the gap N3 is narrow, there is a risk that the sealant S will not fully reach the front surface of the rear surface portion 522 from the front, but it is preferable to ensure that the gap N3 is wide enough to prevent this from happening. The material of the sealant receiving member 123 is the same as that of the above-described sealant receiving member 110. The sealant receiving member 123 may be fixed in the above-described arrangement by adhesive or the like.

[0098] 19, the sealing material S is filled into the rectangular parallelepiped filling area between the lower surface of the sealant receiving member 123 and the upper surface of the top surface 225, without any gaps, including the upper surface of the top surface 225, the lower surface of the sealant receiving member 123, the right surface of the vertical plate portion 523, the front surface of the rear surface portion 522, the left surface of the vertical plate portion 511, and the corners of each surface. After filling, the sealing material S is preferably adjusted so that its front surface is flush with the front surfaces of the extension portions 524 and 526 or bulges slightly forward. This seals the gap between the upper surface of the top surface 225 of the lower frame 2 and the lower end surface of the rear surface 522 and vertical plate portion 523 of the right vertical frame 5 with sealing material S, ensuring water resistance between the right vertical frame 5 and the lower frame 2.

[0099] [Sealing structure of mold material (4)] Since the externally movable shoji screen 8 is constructed by connecting and assembling multiple molded pieces, it is difficult to maintain sufficient watertightness unless special treatment is performed between the molded pieces, and water resistance decreases. For this reason, the externally movable shoji screen 8 is provided with a molded seal structure (4) using a seal material S at the connection between the lower frame 81 and the left vertical frame 85. As one aspect of the seal structure of the mold material, a seal structure (4) of the mold material that is constructed at the connection between the bottom frame 81 and the left vertical frame 85 of the externally movable shoji screen 8 will be described with reference to Figs. Figure 20 is an oblique view of the connection point between the bottom frame 81 and the left vertical frame 85 of an externally movable shoji screen 8 on which a molding sealing structure (4) has been installed, Figure 21 is an oblique view of the connection point between the bottom frame 81 and the left vertical frame 85, illustrating the inside of the left vertical frame 85 of the configuration in Figure 20, Figure 22 is an oblique view of the left vertical frame 85 before being assembled to the bottom frame 81, and Figure 23 is an oblique view showing the state in which the left vertical frame 85 is connected to the bottom frame 81.

[0100] The lower frame 81 and the left vertical frame 85 are connected by fastening members such as screws, bolts, etc. so that the left end face of the lower frame 81 and the right face of the partition wall 856 of the left vertical frame 85 are pressed against each other in the left-right direction. A sheet-like sealing material 124 such as a mat sealer is inserted between the left end face of the lower frame 81 and the partition wall 856 of the left vertical frame 85. In other words, the seal structure (4) of the mold is provided on the premise that watertightness is already ensured between the left end face of the lower frame 81 and the right face of the partition wall portion 856 of the left vertical frame 85.

[0101] The connection points between the frames where the molding seal structure (4) is applied satisfy the conditions (ia) and (iiib) instead of (i) and (iiia) of the above-mentioned conditions (i), (iia), and (iiia). (ia) Between the two connected frames, the two opposing surfaces facing each other at the position facing the interior space are sealed with a fillable sealant. (iia) The two opposing surfaces are located on the interior side of the glass, beyond the sealing material on the periphery. (iiib) Between two connected frames, the space between the two opposing surfaces is sealed from the inside of the frame with a fillable sealant.

[0102] The rear surface 853, right surface 854, and abutment piece 855 of the left vertical frame 85 have a rectangular cutout portion 85a cut out from the right side when viewed from behind, and the upper part of the rear surface 813 of the lower frame 81 fits into this cutout portion 85a, connecting the lower frame 81 and the left vertical frame 85. The two opposing surfaces sealed by the sealing material S are two sets: the lower end surface within the cutout portion 85a in the right surface portion 854 of the left vertical frame 85 and the upper surface of the top surface portion 814 of the lower frame 81, and the lower end surface within the cutout portion 85a in the rear surface portion 853 of the left vertical frame 85 and the upper surface of the top surface portion 814 of the lower frame 81. The two pairs of opposing surfaces are both opposed to each other at positions facing the interior space between the two connected frames, the lower frame 81 and the left vertical frame 85 (condition (ia)). Both of the two pairs of opposing surfaces are located closer to the interior of the room than the sealing material 891 of the glass 89 (condition (iia)). Both of the two pairs of opposing surfaces are sealed with a sealing material S from the front side of the rear surface portion 853 of the left vertical frame 85 (the inside of the left vertical frame 85) (condition (iiib)). The conditions (ia), (iia), and (iiib) are merely examples and are not intended to limit the scope of the present invention. The sealing structure (4) may be installed at any location where flood-resistant sash 100 may allow water to enter the interior of the room.

[0103] Next, the construction order and details of the seal structure (4) of the mold material will be explained. First, as shown in FIG. 22, the sealant receiving member 150 is attached to the area surrounded by the rear surface 853, right surface 854, abutment piece 855, and partition wall 856 of the left vertical frame 85, above the cutout 85a. 21 , the sealant receiving member 150 is a triangular prism having a right-angled triangular shape when viewed from the left and right. One of the right-angled triangular end faces of the sealant receiving member 150, the right end face, abuts against the left face of the right face portion 854, and the other of the right-angled triangular end faces, the left end face, abuts against the right face of the partition wall portion 856. The front face of the sealant receiving member 150 abuts against the rear face of the abutment piece 855, and the top face of the sealant receiving member 150 is horizontal. The inclined surface parallel to the hypotenuse of the right triangle of the sealant receiving member 150 faces diagonally downward and rearward, and faces diagonally both the front surface of the rear surface portion 853 and the upper surface of the top surface portion 814 when the lower frame 81 is connected. The sealant receiving member 150 is disposed so that its lower end (the lower end of the inclined surface) is at the same height as the lower end surface of the right surface portion 854. The material of the sealant receiving member 150 is the same as that of the above-described sealant receiving member 110. The sealant receiving member 150 may be fixed in the above-described arrangement by adhesive or the like.

[0104] 21 and 23, the sealant receiving member 150 is positioned as described above, and the lower frame 81 and the left vertical frame 85 are connected via the sheet-like sealant 124. As a result, a filling area for the sealant S having a substantially right-angled triangular prism shape is formed below the slope of the sealant receiving member 150, surrounded by the slope, the right face of the partition wall portion 856, the left face of the right face portion 854, the front face of the rear face portion 853, and the upper face of the top face portion 814 of the lower frame 81. A filling hole 853a for the sealing material S, which is electrically connected to the filling area from the outside, is formed through the rear surface portion 853. The rear surface portion 853 also has a slit-shaped confirmation hole 853b for checking the filling state of the sealing material S, which is formed so that a slight gap is generated between the lower end surface of the cutout portion 85a in the rear surface portion 853 and the upper surface of the top surface portion 814 of the lower frame 81. Then, the sealing material S is filled into the filling area from the rear side of the left vertical frame 85 through the filling hole 853a. At this time, it is preferable to fill the sealing material S so that the sealing material S is injected from the front end side of the filling area. The filling of the sealing material S is continued at least until the sealing material S leaks out from the confirmation hole 853b. This makes it possible to confirm that the sealing material S has spread without gaps over at least the entire lower part of the filling area. As a result, the sealing material S seals between two pairs of opposing surfaces: the lower end surface of the cutout portion 85a on the right side 854 of the left vertical frame 85 and the upper surface of the top surface 814 of the lower frame 81, and the lower end surface of the cutout portion 85a on the rear side 853 of the left vertical frame 85 and the upper surface of the top surface 814 of the lower frame 81, ensuring water resistance between the lower frame 81 and the left vertical frame 85. In addition, the same sealing structure as the sealing structure (4) of the mold is also provided between the lower frame 81 and the right vertical frame 87. The triangular prism shape of seal receiving member 150 is merely an example and is not limited thereto. For example, any shape may be used that can form an enclosed space inside left vertical stile 85 that communicates with two pairs of opposing surfaces: the lower end surface of notch 85a in right surface 854 of left vertical stile 85 and the upper surface of top surface 814 of bottom stile 81, and the lower end surface of notch 85a in rear surface 853 of left vertical stile 85 and the upper surface of top surface 814 of bottom stile 81, and that communicates with filling hole 853a and confirmation hole 853b.

[0105] [Watertight material guide] Figure 24 is an oblique view of the lower frame 2 and left vertical frame 4 with waterproof material guide devices 160, 170 attached, and Figure 25 is an oblique view of the lower frame 2 and mullion 6 with waterproof material guide devices 180, 190 attached. A sheath for storing watertight material 101 is provided on the front side of the frame body 10, in close contact with the periphery of a rectangular opening 801 facing the glass 89 of the externally movable shoji screen 8, to provide a watertight seal between the externally movable shoji screen 8 and the frame body 10. The watertight material 101 is arranged in a rectangular shape on the front side of the frame body 10. This sheath is made up of: sheath 235 consisting of a pair of ridges 235a provided along the left-right direction on the front of the front part 232 of the cover member 23 of the lower frame 2; sheath 335 consisting of a pair of ridges 335a provided along the left-right direction on the front of the front part 332 of the cover member 33 of the upper frame 3; sheath 425 consisting of a pair of ridges 425a provided along the up-down direction on the front of the front part 421 of the left vertical frame 4; and sheath 625 consisting of a pair of ridges 625a provided along the up-down direction on the front of the front part 621 of the mullion 6.

[0106] 24, the watertight material 101 is arranged so as to pass through the exposed portion of the sealing material S filled in the region R1 at a corner in the arrangement path of the watertight material 101 between the lower end of the sheath portion 425 and the left end of the sheath portion 235. The lower end of the pair of ridges 425a of the sheath portion 425 and the left end of the pair of ridges 235a of the sheath portion 235 both have their tip portions removed so as to be separated from the corner in the arrangement path of the watertight material 101 or the exposed portion of the sealing material S.

[0107] In the removed portions of the pair of ridges 235a of the sheath portion 235 and the pair of ridges 425a of the sheath portion 425, watertight material guide devices 160, 170 having guide portions 161, 171 for the watertight material 101 are provided in place of the pair of ridges 235a, 425a. The waterproof material guide device 160 includes a guide portion 161 consisting of a convex strip shaped to connect the lower convex strip 235a and the left-side convex strip 425a at a right angle, and a fixing portion 162 for fixing the guide portion 161 to the surface of either the lower frame 2, the cover member 23 or the left vertical frame 4 by sticking or bonding, etc. In addition, the waterproof material guide device 170 is equipped with a guide portion 171 consisting of a convex strip shaped to connect the upper convex strip 235a and the right-side convex strip 425a at a right angle, and a fixing portion 172 for fixing the guide portion 171 to the surface of either the lower frame 2, the cover member 23 or the left vertical frame 4 by sticking or bonding, etc. These watertight material guide devices 160 and 170 allow the watertight material 101 to be properly guided at the corner between the sheath portion 235 and the sheath portion 425.

[0108] 25, between the lower end of the sheath portion 625 and the right end of the sheath portion 235, the watertight material 101 is arranged so as to pass through the exposed portion of the sealing material S filled in the region R3 at the corner of the arrangement path of the watertight material 101. The lower end of the pair of ridges 625a of the sheath portion 625 and the right end of the pair of ridges 235a of the sheath portion 235 both have their tip portions removed so as to be separated from the corner of the arrangement path of the watertight material 101 or the exposed portion of the sealing material S.

[0109] In the removed portions of the pair of ridges 235a of the sheath portion 235 and the pair of ridges 625a of the sheath portion 625, watertight material guide devices 180, 190 having guide portions 181, 191 for the watertight material 101 are provided in place of the pair of ridges 235a, 625a. The waterproof material guide device 180 comprises a guide portion 181 consisting of a convex rib shaped to connect the upper convex rib 235a and the left convex rib 625a at a right angle, and a fixing portion 182 for fixing the guide portion 181 to the surface of either the lower frame 2, the cover member 23 or the upright 6 by sticking or bonding, etc. The waterproof material guide device 190 also has a guide portion 191 consisting of a convex rib shaped to connect the lower convex rib 235a and the right-side convex rib 625a at a right angle, and a fixing portion 192 for fixing the guide portion 191 to the surface of either the lower frame 2, the cover member 23 or the upright 6 by sticking or bonding, etc. These watertight material guide devices 180 and 190 allow the watertight material 101 to be properly guided at the corner between the sheath portion 235 and the sheath portion 625.

[0110] The significance of the above-mentioned watertight material guide tools 160 to 190 will be explained with reference to Figures 26 to 29. Figures 26 and 27 are diagrams showing a sheath portion (sheath portion 425 is shown as an example) provided with a pair of convex strips protruding from a plane, such as sheath portions 235, 335, 425, and 625, and Figures 28 and 29 are diagrams showing a guide structure 425X of the watertight material 101 consisting of a recessed groove recessed from a plane. The corners of the path of the watertight material 101 are the connection parts between the frame members, and the path may be set so that it necessarily passes through the exposed part of the sealant S. The connection parts between the frame members may have unevenness due to misalignment of the surfaces of the members, and when the watertight material 101 passes over it, gaps may be created and the sealing performance may be reduced. In particular, when passing over the exposed part of the sealant S, the sealant S may bulge, and when the watertight material 101 passes over it, gaps may be created and the sealing performance may be reduced. Therefore, before installing the watertight material 101, it is necessary to smooth out the above-mentioned steps and protrusions. In this case, the unevenness of the sheath 425 and the guide structure 425X, which are composed of a pair of ridges 425a protruding from the plane, hinders the above-mentioned smoothing process, as shown in Figures 26 and 28. In this case, as shown in Figure 27, by removing the pair of ridges 425a from the surface, it becomes possible to easily and effectively smooth out the steps and protrusions. In contrast, in the case of the guide structure 425X, which is composed of grooves, the unevenness can be removed only partially at most, as shown in Figure 29, and the area around the watertight material 101 cannot be completely flattened, so smoothing out the steps and protrusions remains difficult.

[0111] Therefore, in the case of the sheath portion 235, 335, 425, 625 in which a pair of protruding ridges are provided above a flat surface, the sealing properties of the watertight material can be enhanced, and the water-resistant sash 100 can be improved in water-resistance. Furthermore, by equipping the area where the pair of protrusions 235a, 425a have been removed with the aforementioned watertight material guide devices 160-190, the watertight material 101 can be maintained in a properly positioned state, which also improves the water resistance of the flood-resistant sash 100.

[0112] [Technical Effects of the Embodiments of the Invention] In the above-mentioned flood-resistant sash 100, the spaces between the two opposing surfaces of the connected frame members, such as the bottom frame 2, left vertical frame 4, right vertical frame 5, upright 6, and cover member 23, are sealed with a fillable sealing material S. Therefore, even if the bottom frame 2, left vertical frame 4, right vertical frame 5, upright 6, and cover member 23 are made of extruded molding material, water can be effectively prevented from seeping in between the surfaces of the molding material, making it possible to prevent water from seeping in due to rising water levels outside the room, etc.

[0113] Furthermore, in the flood-resistant sash 100, the two opposing surfaces of the connected frame members, such as the sill 2, left vertical frame 4, right vertical frame 5, mullion 6, and cover member 23, that face the interior space are sealed with a sealant S. In other words, because the sealant S seals the outlet to the interior side of the water-resistant sash 100, rather than the inlet, the number of sealed locations can be minimized, making it possible to efficiently implement flood-resistant treatment. Furthermore, because the number of sealed locations is reduced, it is possible to reduce the possibility of water entering through sealed locations.

[0114] Furthermore, the water-resistant sash 100 has a gap for filling the sealant S between two opposing surfaces of the connected bottom frame 2, left vertical frame 4, right vertical frame 5, mullion 6, cover member 23, etc. This prevents a decrease in sealing performance due to insufficient penetration of the sealant S caused by the gap between the two opposing surfaces being too narrow, and makes it possible to maintain high water resistance.

[0115] Furthermore, the water-resistant sash 100 has sealant receiving members 110, 121, 130, 140, 150 that form a filling space for the sealant S positioned closer to the internal space of the frame members, such as the bottom frame 2, left vertical frame 4, right vertical frame 5, mullion 6, and cover member 23, than between the two opposing surfaces of the connected bottom frame 2, left vertical frame 4, right vertical frame 5, mullion 6, and cover member 23. Therefore, the sealant S in the filling space can support the sealant S from behind between the two opposing surfaces, thereby maintaining the proper positioning of the sealant S and preventing the sealant S from slipping beyond the two opposing surfaces, making it possible to maintain high water-resistant properties.

[0116] In addition, the water-resistant sash 100 has a seal between the bottom frame 2 and the cover member 23 with sealing material S, so even if the bottom frame 2 and the cover member 23 are made of extruded molding material, water can be effectively prevented from seeping in between the surfaces of the molding material, making it possible to prevent water from seeping in due to rising water levels outside the room, etc.

[0117] Furthermore, the two opposing surfaces of the flood-resistant sash 100 that face each other within the range of the waterproof material 101 on the indoor side are sealed with a sealing material S. The sealing effect of the watertight material 101 can prevent water from seeping in on the outdoor side of the watertight material 101, so sealing can be applied only to areas where it is most necessary, making it possible to efficiently apply water-resistant treatment. In addition, since the number of sealed areas is reduced, it is possible to reduce the possibility of water seeping in from sealed areas.

[0118] The flood-resistant sash 100 also has a sheath portion 235, 425, 625 for storing the watertight material 101, which is made up of a pair of protruding strips 235a, 425a, 625a that protrude toward the external moving shoji screen on the surface of the frame body 10 facing the external moving shoji screen 8. This structure makes it possible to easily remove the pair of convex ridges 235a, 425a, 625a in the area when smoothing of steps or unevenness is required, thereby allowing the smoothing to be carried out properly and maintaining high sealing performance of the watertight material 101.

[0119] Furthermore, when the flood-resistant sash 100 is arranged so that the watertight material 101 passes through the filling point of the sealing material S, the sheath portion 235, 425, 625 is not provided around the filling point, so that unevenness caused by the bulging sealing material S can be properly smoothed out, making it possible to maintain the sealing performance of the watertight material 101 at an even higher level.

[0120] Furthermore, the flood-resistant sash 100 is fitted with watertight material guide devices 160-190 that guide the watertight material instead of the sheath portions 235, 425, 625 around the filling area, so that even if the sheath portions 235, 425, 625 are not provided, it is possible to maintain the watertight material 101 in the correct position, thereby enabling the sealing performance of the watertight material 101 to be maintained at an even higher level.

[0121] Furthermore, the flood-resistant sash 100 has a fillable sealing material S filled between the bottom frame 81 and the glass groove of the left vertical frame 85 of the externally movable shoji screen 8. Therefore, even if the bottom frame 81 and the left vertical frame 85 are made of extruded molding material, water can be effectively prevented from seeping in between the surfaces of the molding material, making it possible to prevent water from seeping in due to rising water levels outside the room.

[0122] Furthermore, the flood-resistant sash 100 has a sealant S filled between two opposing surfaces between the left vertical frame 85 of the externally movable shoji screen 8. In this case, the sealant S tightly adheres to the opposing surfaces to form a seal, making it possible to suppress flooding due to rising water levels outside the room with high sealing properties.

[0123] In addition, the flood-resistant sash 100 has a filling hole 853a for the sealing material S formed on the indoor side of the left vertical frame 85 of the externally movable shoji screen 8, making it easy to fill the sealing material S on the inside of the left vertical frame 85 and the right vertical frame 87 from the outside, making it possible to facilitate the installation of the flood-resistant sash 100.

[0124] In addition, the water-resistant sash 100 has a hole 853b formed in the left vertical frame 85 of the externally movable shoji screen 8 for checking the filling status of the sealing material S, making it possible to confirm that the sealing material S is filled in the correct state, thereby making it possible to maintain a high level of effectiveness in preventing water from entering the room.

[0125] Furthermore, the water-resistant sash 100 has a sealant receiving member 150 that forms a filling space for the sealant S on the internal space side of the glass groove of the left vertical frame 85 of the externally movable shoji screen 8, so that the filling space allows the sealant S to be positioned in the appropriate position and held in that position, thereby making it possible to maintain high water resistance.

[0126] Furthermore, since the sealant receiving member 150 is formed in a triangular prism shape, it is possible to easily form a space for filling the sealant S in a rectangular parallelepiped space. Furthermore, the triangular prism shape makes it possible to easily form the sealant receiving member 150 itself, and also makes it possible to form it without waste from the materials used, which is cost-effective.

[0127] Furthermore, since the sealing material receiving member 150 forms a filling space for the sealing material S with its inclined surface and the inner surface of the left vertical frame 85, there is no need for the sealing material receiving member 150 to have a complex shape, making it easier to manufacture and more cost-effective.

[0128] In addition, the flood-resistant sash 100 is configured such that the bottom frame 81 and left vertical frame 85 of the externally movable shoji screen 8 are connected by a fastening member, and a sheet-like sealing material 124 is interposed between the end face of the bottom frame 81, which is pressed against each other by the fastening member, and the opposing face of the left vertical frame 85. Therefore, sealing is ensured in many parts of the externally movable shoji screen 8, making it possible to reduce the number of places where the sealing material S is filled. This makes it possible to efficiently perform water-resistant treatment. In addition, because the number of sealed places is reduced, it is possible to reduce the possibility of water seeping in through the sealed places.

[0129] [others] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments. For example, in the embodiments, a component integrally formed from a single member may be replaced with a component divided into multiple members that are connected or fixed to each other. Furthermore, a component formed by connecting multiple members may be replaced with a component integrally formed from a single member. In addition, the details shown in the embodiments may be modified as appropriate without departing from the spirit of the invention.

[0130] The flood-resistant sash 100 is exemplified as an externally movable single sliding window sash, but is not limited to this. For example, the sealing structure of the various mold materials described above can be applied to sashes that entirely hold fixed glass. Furthermore, the shoji screens included in the flood-resistant sash 100 are not limited to the externally movable shoji screens 8, but may be fixed, outward-opening, inward-opening, or sliding shoji screens.

[0131] Furthermore, the sealing structure of the mold material has been exemplified as being configured around the lower frame 2, cover member 23 and lower stile 81, but this is not limited to this and it may also be configured around the upper frame 3, cover member 33 and upper stile 83.

[0132] Furthermore, the watertight material 101 is not limited to the illustrated form, and other watertight materials that can seal between the shoji screen and the frame body may be used. For example, a watertight material having a lip that rises from the frame body toward the shoji screen may be used. [Explanation of symbols]
