[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 4 show one embodiment of an opening device 17 of the present invention. As shown in Figures 1 and 2, this opening device 17 is applied to a fixed window installed in an opening 16 on the indoor side of a curtain wall 15 that forms the exterior wall of a building.

[0008] As shown in Figures 1 and 2, the curtain wall 15 is made up of multiple mullions 18, 18, ... fixed to the main body (not shown) and spaced apart in the left-right direction, with transoms 19a, 19b attached at intervals in the up-down direction between the mullions 18, 18, ... As shown in Figure 1, this curtain wall 15 has a vision section 20 facing the living space and a spandrel section 21 facing the boundary between the upper and lower floors. The vision sections 20 and spandrel sections 21 are arranged alternately in the up-down direction.

[0009] The mullion 18 is made of aluminum extrusion and, as shown in Figure 2, has a main body 22 with a rectangular cross section on the indoor side, and a front wall 23 and a front wall 24 on the outdoor side of the main body 22, forming a T-shape. Mounting grooves 25a, 25b are formed on the right and left sides of the front wall 23. The mullion 18 is formed continuously across the vision section 20 and the spandrel section 21, and is fixed to the frame with fasteners (not shown).

[0010] As shown in Figure 2, in the vision section 20, the left and right ends of glass (double-glazed glass) 26 are inserted into the mounting grooves 25a, 25b on the outdoor side of the adjacent left and right mullions 18, 18, a flange 27 is attached to the indoor side of the glass 26 in the mounting grooves 25a, 25b, and a sealant 28 is filled between the outdoor side of the flange 27 and the indoor side of the glass 26, and between the visible wall 24 of the mullion 18 and the outdoor side of the glass 26, to hold the glass 26 in place.

[0011] As shown in Figure 1, the transom 19b located below the vision section 20 has a hollow section 29 on the indoor side, and ridges 30a, 30b attached to the outdoor side, with a glass holding groove 31a that opens upward and a glass holding groove 31b that opens downward. The lower end of the glass 26 of the vision section 20 is inserted into the upward-opening glass holding groove 31a, and the outdoor and indoor sides of the glass 26 are filled with sealant 32 to secure the glass 26 in place. The upper end of the glass 33 of the spandrel section 21 is inserted into the downward-opening glass holding groove 31b, and the indoor side is supported by a gasket 34, and the outdoor side is filled with sealant 35 to secure the glass 33 in place. The transom 19a located above the vision section 20 has approximately the same shape as the transom 19b below the vision section described above, and the upper end of the glass 26 of the vision section 20 is inserted into the downward-opening glass holding groove 31b, and the glass 26 is fixed by filling sealing material 32 on the outside and inside of the room.The lower end of the glass 33 of the spandrel section 21 is inserted into the upward-opening glass holding groove 31a, and the inside of the room is supported by a gasket 34, and the outside of the room is filled with sealing material 35 to fix the glass 33.

[0012] As shown in Figure 1, a steel member 36 is attached to the interior side of the transom 19a located above the vision section 20, and a metal tray 37 is provided so as to continue from the underside of the transom 19a toward the interior side. A steel member 36 is also attached to the interior side of the transom 19b located below the vision section 20, and a metal tray 37 is provided so as to continue from the top surface of the transom 19b toward the interior side.

[0013] As shown in FIGS. 1 and 2, the opening device 17 is installed in the opening 16 formed by the upper and lower trays 37, 37 and the facing surfaces of the left and right mullions 18, 18. This opening device 17 comprises an upper frame 1, a lower frame 2 and left and right vertical frames 3, 3 which are attached to the inner surfaces 16a, 16b, 16c, 16d of the opening 16 on all four sides, a vertical frame 4 erected between the upper frame 1 and the lower frame 2 at the midpoint in the left-right direction, and an exterior glass door (door on the exterior side) 5a and an interior glass door (door on the interior side) 5b arranged in a sliding manner within the four surrounding frames (upper frame 1, lower frame 2 and left and right vertical frames 3, 3), and the exterior glass door 5a and the interior glass door 5b are fixed to the vertical frames 4 with fixing means 14, thereby forming a fixed window. Therefore, although this opening device 17 is a fixed window, by releasing the fixing means 14, the exterior glass door 5a and the interior glass door 5b can be opened, closed, attached and removed like a sliding window. In addition, this opening device 17 uses fireproof glass such as heat-resistant crystallized glass for the glass 9 of the exterior glass door 5a and the interior glass door 5b, and by installing this opening device 17, fireproof performance can be imparted to the opening 16 of the building.

[0014] The upper frame 1 is made of extruded aluminum alloy and, as shown in Figures 1 and 3, has three grooves 38a, 38b, and 38c, each open on its inner periphery, lined up in the indoor / outdoor direction. The upper edge of the exterior glass door 5a is fitted into the outer groove 38a, and the upper edge of the interior glass door 5b is fitted into the interior groove 38c. The middle groove 38b is closed with a batten 39. As shown in Figure 11, a cap 85 is attached to the end of the batten 39 on the vertical frame 4 side. As shown in Figures 1 and 5(a), the upper frame 1 has thermal expansion material 40 provided along the longitudinal direction at two locations on the outer peripheral side, one on the outdoor side and one on the indoor side, and is fixed with screws 41 in contact with the inner peripheral surface 16a above the opening 16. The thermal expansion material 40 is a known material that expands when heated to a predetermined temperature (specifically, a temperature of 150°C to 250°C) to form a heat insulating layer, and one example of this is Fi-Block, a product name manufactured by Sekisui Chemical Co., Ltd. By providing the thermal expansion material 40 on the outer peripheral side of the upper frame 1 in this way, even if the upper frame 1 deforms during a fire and a gap is created between it and the inner peripheral surface 16a of the opening, the expanded thermal expansion material 40 will close the gap and prevent the flames from passing through (the same applies to the lower frame 2 and vertical frame 3 described below).

[0015] The lower frame 2 is formed from an extruded aluminum alloy member, and as shown in FIGS. 1 and 3, three grooves 12a, 12b, and 12c, each open on its inner periphery, are formed in a line extending from the inside to the outside of the room. A rail 42 that supports the exterior glass door 5a is formed to protrude upward in the exterior groove 12a (the running section of the exterior door 5a), and the lower edge of the exterior glass door 5a is supported by the rail 42 and is fitted into the exterior groove 12a. A rail 42 that supports the interior glass door 5b is formed to protrude upward in the interior groove 12c (the running section of the interior door 5b), and the lower edge of the interior glass door 5b is supported by the rail 42 and is fitted into the interior groove 12c.

[0016] As shown in Figures 3 and 4, the outside groove 12a, along with the middle groove 12b, is blocked by a batten 13a on the trailing edge side of the exterior glass door 5a when it is closed. The inside groove 12c, along with the middle groove 12b, is blocked by a batten 13b on the trailing edge side of the interior glass door 5b when it is closed. By blocking the grooves 12a, 12b, and 12c of the sill 2 with battens 13a and 13b in this way, the movement of the exterior glass door 5a and the interior glass door 5b is restricted and dirt is prevented from entering the grooves 12a, 12b, and 12c. 4 and 12, the battens 13a and 13b are provided with thermal expansion material 43 along the grooves 12a, 12b, and 12c on the underside of the end portion on the vertical frame 4 side. In addition, resin corner caps 44 are attached to the end portions of the battens 13a and 13b on the vertical frame 3 side, and the corner caps 44 hide the gaps between the battens 13a and 13b and the battens 45a and 45b of the vertical frame 3, which will be described later.

[0017] 1 and 5(a), like the upper frame 1, the lower frame 2 has thermal expansion material 40 provided along the longitudinal direction at two locations on the outer peripheral side, one on the outdoor side and one on the indoor side, and is fixed in place by screws 46 against the inner peripheral surface 16b below the opening 16. A vertical frame fixing piece 47, to which the lower end of the vertical frame 4 is fixed, is attached by fitting at the center position in the longitudinal direction of the lower frame 2. Furthermore, as shown in Figures 4 and 5(b), the bottom frame 2 has a thermal expansion material 48 provided at the left end, as viewed from the inside of the room, where the exterior glass door 5a is located, spanning the bottom surfaces of the exterior groove 12a and the middle groove 12b, and a thermal expansion material 48 provided at the right end, as viewed from the inside of the room, where the interior glass door 5b is located, spanning the bottom surfaces of the interior groove 12c and the middle groove 12b.

[0018] As shown in Figures 2 and 4, the left and right vertical frames 3 are double-layered, consisting of an outer vertical frame 49 and an inner vertical frame 50. The inner vertical frame 50 has the same projected dimensions as the upper frame 1 and the lower frame 2, while the outer vertical frame 49 has a slightly larger projected dimension. The outer vertical frame 49 is made of extruded aluminum alloy and, as shown in Figure 4, has a U-shaped cross section with exterior and interior side facing walls 51 and 52 that are open on the interior side. As shown in Figures 5(a) and 14-1, the exterior vertical frame 49 has thermal expansion material 40 provided along the longitudinal direction at two locations on the exterior and interior sides of the outer peripheral side, and is fixed with screws 53 in contact with the left and right inner peripheral surfaces 16c, 16d of the opening 16. A gasket 54 (see Figure 5(a)) is affixed to the upper end of the outer vertical frame 49 to seal the gap with the upper inner peripheral surface 16a of the opening 16. As shown in FIG. 14-3, the outer vertical frame 49 is provided over the entire height of the opening 16, and the longitudinal ends of the upper frame 1 and the lower frame 2 are inserted into the outer vertical frame 49.

[0019] The inner vertical frame 50 is made of an extruded aluminum alloy and, as shown in Figures 2 and 4, is placed inside the outer vertical frame 49 and secured in place with screws 82 from the inside. Similar to the upper frame 1 and lower frame 2, the inner vertical frame 50 has three grooves 55a, 55b, and 55c that are open on the inner side and aligned in the indoor / outdoor direction. The inner vertical frame 50 on the left side, as seen from the inside of the room where the exterior glass door 5a is located, has a thermal expansion material 56 provided along the longitudinal direction on the inside surface of the exterior side of the exterior groove 55a, and a pull-in piece 57 is fitted into the exterior groove 55a. The leading edge of the exterior glass door 5a is swallowed into the exterior groove 55a of the inner vertical frame 50, and the leading edge is clamped by the pull-in piece 57, restricting play as it is pulled toward the interior. The interior groove 55c and the middle groove 55b are closed with a batten 45a. The right-hand inner vertical frame 50, as seen from the inside of the room where the indoor glass door 5b is located, has a thermal expansion material 56 provided along the longitudinal direction on the inside surface of the indoor groove 55c, and a pull-in piece 57 is fitted into the indoor groove 55c. The leading edge of the indoor glass door 5b is swallowed into the indoor groove 55c of the inner vertical frame 50, and the leading edge is clamped by the pull-in piece 57, restricting play when pulled to the outside. The outdoor groove 55a and the middle groove 55b are closed with a batten 45b. In the event of a fire, the thermal expansion material 56 provided in the grooves 55a, 55c of the inner vertical frame 50 expands, sealing the gap between the leading edge of the exterior glass door 5a and the interior glass door 5b and the inner vertical frame 50, thereby preventing the flames from spreading.

[0020] The vertical frame 4 is formed from an extruded aluminum alloy section, and as shown in Figures 4 and 10, has a hollow main body 58 with a roughly rectangular cross section, engagement parts 60, 60 with which the smoke deflectors 59 of the exterior glass door 5a and the interior glass door 5b engage, and weatherstripping material holder parts 61, 61 located adjacent to the sides of the engagement parts 60, 60, with the positions of the engagement parts 60 and weatherstripping material holder parts 61 reversed on the left and right sides on the exterior and interior sides. Weatherstripping material 62 is attached to the weatherstripping material holder parts 61, and the weatherstripping material 62 covers the outer surface of the engagement parts 60. As shown in FIG. 10, the vertical frame 4 has the engagement portion 60 and the tension material holder portion 61 removed at the upper end, and thermal expansion material 63 is provided on the exterior and interior sides of the main body portion 58. Furthermore, as shown in Figure 10(a), the vertical frame 4 has notches 64 formed by cutting out the engaging portions 60 on the outside and inside of the room from their bases at predetermined positions in the middle of the longitudinal direction. The notches 64 are provided in two places, at approximately the center and bottom of the vertical frame 4. As shown in Figure 14-5, the upper end of the vertical bone 4 is inserted into the upper frame 1, and the lower end is inserted into the vertical bone fixing piece 47 attached to the lower frame 2 to fix it, and as shown in Figure 14-6, the upper end of the vertical bone 4 is fixed by clamping it from all sides with metal fittings 65, 65 attached to the upper frame 1.

[0021] As shown in Figures 13 and 14-4, the exterior glass door 5a has a glass 9 made of fireproof glass, a bottom frame 6 that holds the bottom edge of the glass 9, a joint frame 7 that holds the joint side edge of the glass 9, and a sway stopper 66 attached to the top edge of the glass 9. There are no frames on the top edge side or the door tip side of the glass 9.

[0022] The bottom frame 6 is made from an extruded aluminum alloy and, as shown in Figures 3 and 8, has a roughly H-shaped cross section with a groove-shaped glass opening 10 that is open on the inner periphery and a rail-receiving groove 67 that is open on the outer periphery. A thermal expansion material 11 is bonded to the entire length of the opposing inner surfaces of the glass opening 10. A base plate 68 that supports the glass 9 is placed at the bottom of the glass opening 10. Within the rail swallowing groove 67, a slide piece 69 that abuts against the upper end of the rail 42 of the lower frame 2 and a sway stopper 70 that clamps the rail 42 of the lower frame 2 from the outside and inside of the room are provided at intervals in the longitudinal direction of the lower frame 6. As shown in Figures 8 and 13, a metal fitting 71 is attached to the joint side end of the bottom frame 6 to connect it to the joint frame 7, and a plastic cap 72 is attached to the door tip side end of the bottom frame 6.

[0023] The joint frame 7 is made of extruded aluminum alloy material, and as shown in Figures 4 and 9, it has a groove-shaped glass opening 10 that is open on the inner periphery, and a hook-shaped smoke deflector 59 that bends inward on the room side. A thermal expansion material 11 is attached to the entire length of the inner surface of the glass opening 10 facing the glass. As shown in Figure 13, the smoke deflector 59 has a notch 73 cut out from the base at a predetermined position in the middle of its longitudinal direction. The notch 73 is located at the same height as the notch 64 of the vertical frame 4 described above.

[0024] As shown in Figures 13 and 15, the exterior glass door 5a is assembled by first attaching thermal expansion material 11 to the glass opening 10 of the bottom frame 6 and the glass opening 10 of the joint frame 7, fitting the bottom edge of the glass 9 into the glass opening 10 of the bottom frame 6, fitting the joint side edge of the glass 9 into the glass opening 10 of the joint frame 7, and connecting the bottom frame 6 and the joint frame 7 with metal fittings 71 in a state where the joint side end face of the bottom frame 6 is abutting against the inner peripheral edge of the joint frame 7. The glass 9 is held in place so that it does not come out of the glass opening 10 by the thermal expansion material 11 attached to the opposing inside surfaces of the glass opening 10 of the bottom frame 6 and the joint frame 7.

[0025] In this way, by using the thermal expansion material 11 to hold the glass 9 in the glass opening 10, the installation of the glass 9 and the assembly of the glass doors 5a, 5b can be easily performed, improving workability. Moreover, in the event of a fire, the expansion of the thermal expansion material 11 makes it even more difficult for the glass 9 to fall out of the glass opening 10.

[0026] The interior glass door 5b is constructed in the same manner as the above-mentioned exterior glass door 5a. As shown in Figure 4, the door frame 7 of the interior glass door 5b has a smoke deflector 59 formed on the exterior side.

[0027] As shown in Figure 4, the exterior glass door 5a and the interior glass door 5b each have a fixing means 14 that fixes the smoke deflector 59 provided on the door frame 7 in the closed position where it engages with the engaging portion 60 of the vertical frame 4. 7 and 14-9, the fixing means 14 in this embodiment is composed of a fixing hook 74 formed by pressing a metal plate and mating covers 8a and 8b to which the fixing hook 74 is attached. The fixing hook 74 has an attachment plate portion 75 and a protruding hook portion 76 whose tip is bent downward. As explained above, the smoke deflectors 59 of the joint frames 7 of the exterior glass door 5a and the interior glass door 5b and the engagement part 60 of the vertical frame 4 have notches 73, 64 at the same height. As shown in Figure 14-9, with the smoke deflectors 59 and the engagement part 60 engaged, the hook part 76 is inserted into the notches 73, 64 from the outer periphery of the glass doors 5a, 5b, and then the fixing hook 74 is moved downward and the hook part 76 is inserted into the empty part 77 in the tension material holder part 61 of the vertical frame 4, thereby fixing the glass doors 5a, 5b so that they do not move.

[0028] As shown in Figure 4, this opening device 17 has an exterior door frame cover 8a that straddles and covers the door frame 7 and vertical frame 4 of the exterior glass door 5a, and an interior door frame cover 8b that straddles and covers the door frame 7 and vertical frame 4 of the interior glass door 5b. Each joint cover 8a, 8b is formed from an extruded aluminum alloy profile and has an approximately L-shaped cross section with a visible wall 78 covering the visible surfaces of the joint frame 7 and the vertical ribs 4, and a visible wall 79 covering the visible surface of the joint frame 7.

[0029] The fixed hooks 74 are fixed at a predetermined height on the inner peripheral surfaces of the front walls 78 of the outdoor joint cover 8a and the indoor joint cover 8b. Specifically, as shown in Figure 7(a), the mounting plate portion 75 of the fixed hooks 74 is engaged with the inner peripheral surfaces of the front walls 78 of each joint cover 8a, 8b so as to be slidable in the longitudinal direction, and the hook portion 76 is inserted into the notch 81 of the flame catcher 80 formed by bending a stainless steel plate to position the fixed hooks 74, and the flame catcher 80 is fitted across the inner peripheral surfaces of the front walls 78 and the front walls 79 of the joint covers 8a, 8b. In this way, since the fixing hooks 74 are integrated with the door lock covers 8a and 8b, the fixing of the exterior glass door 5a and the interior glass door 5b by the fixing hooks 74 is done at the same time as the installation of the exterior door lock cover 8a and the interior door lock cover 8b.

[0030] Next, the procedure for installing the opening device 17 will be described. First, as shown in FIG. 14-1, the outer vertical frame 49 is attached to the left and right inner peripheral surfaces 16c, 16d of the opening 16 with screws 53. Next, as shown in Figure 14-2, the upper frame 1 is attached to the upper inner peripheral surface 16a of the opening 16, and the lower frame 2 is attached to the lower inner peripheral surface 16b of the opening 16 with screws 41, 46, respectively. At this time, the longitudinal ends of the upper frame 1 and the lower frame 2 are inserted into the outer vertical frame 49. Next, as shown in FIG. 14-3, the inner vertical frame 50 is fitted into the left and right outer vertical frames 49 from the inner periphery side and fixed with screws 82. Next, as shown in FIG. 14-4, the exterior glass door 5a is attached between the exterior groove 38a of the top frame 1 and the exterior groove 12a of the bottom frame 2 by means of an upper and lower clamp. Next, the vertical frame 4 is attached between the upper frame 1 and the lower frame 2. To attach the vertical frame 4, as shown in Figure 14-5(a), the upper end of the vertical frame 4 is inserted into the upper frame 1, and then, as shown in Figure 14-5(b), the lower end of the vertical frame 4 is inserted into the vertical frame fixing piece 47 attached to the lower frame 2 to fix it, and then, as shown in Figure 14-6, metal fittings 65, 65 are attached to the upper frame 1 to clamp and fix the upper end of the vertical frame 4. Next, as shown in Figure 14-7, the batten 39 is attached to the upper frame 1. Next, as shown in FIG. 14-8(a), battens 45a and 45b are attached to the left and right vertical frames 3 and 3. Next, as shown in Figure 14-8(b), a batten 13a is attached to the bottom frame between the vertical frame 3 and the vertical rib 4 on the right side when viewed from inside the room.

[0031] Next, as shown in Figure 14-9, the exterior door frame 8a is attached. To attach the exterior door frame 8a, the hook portion 76 of the fixing hook 74 attached to the exterior door frame 8a is inserted from the outer periphery of the exterior glass door 5a into the notches 73, 64 formed in the smoke deflector 59 and its engagement portion 60, and then the exterior door frame 8a is slid downward until its lower end abuts the upper surface of the batten 13a of the sill 2. Then, the hook portion 76 of the fixing hook 74 is inserted into the hollow portion 77 in the lining material holder portion 61 of the vertical frame 4, which fixes the smoke deflector 59 of the exterior glass door 5a and the engagement portion 60 of the vertical frame 4 so that they do not separate, and the exterior glass door 5a is fixed so that it does not move in the closed position.

[0032] Next, as shown in Figure 14-10, the indoor glass door 5b is attached between the indoor groove 38c of the upper frame 1 and the indoor groove 12c of the lower frame 2 by means of an upper and lower clamp. Next, as shown in Figure 14-11, a batten 13b is attached to the bottom frame 2 between the vertical frame 3 and the vertical rib 4 on the left side when viewed from inside the room. Finally, as shown in Figure 14-12, the indoor door cover 8b is attached in the same way as the outdoor door cover 8a. By attaching the indoor door cover 8b, the indoor glass door 5b is fixed in the closed position so that it does not move.

[0033] This opening device 17 allows the exterior glass door 5a to be opened by removing the exterior door cover 8a, and the interior glass door 5b to be opened by removing the interior door cover 8b. This makes it easy to wipe the exterior surfaces of the glass doors 5a and 5b and clean the exterior window (curtain wall) 15, making maintenance easy. The door cover 8a and 8b can be easily removed by sliding them upwards, in the opposite direction to when they were installed, and then moving them toward the outer periphery of each glass door 5a and 5b.

[0034] FIG. 16(a) shows the state of the joint part of this opening device 17 in the event of a fire, and FIG. 16(b) shows the state of the lower part of this opening device 17 in the event of a fire. In this opening device 17, the glass 9 of the exterior glass door 5a and the interior glass door 5b is held in place in the glass opening 10 of the joint frame 7 and bottom frame 6 by thermal expansion material 11, so that in the event of a fire, the thermal expansion material 11 expands, making it difficult for the glass 9 to fall out of the glass opening 10. Furthermore, as shown in Figures 16(a) and (b), the thermal expansion material 11 that expands and protrudes from the glass opening 10 covers the joint frame 7, vertical frame 4, joint covers 8a and 8b, bottom frame 2 and bottom frame 6, thereby insulating and protecting each of these components and preventing flames from entering through the joint and between the bottom frame 2 and bottom frame 6.

[0035] Figure 17 is a comparative example, showing the state of a fire when glass 9 is held in place by a normal seal bead (not shown) at the glass opening 10 of the joint frame 7. As shown in Figure 17, during a fire, the normal seal bead heats up and burns, creating a gap 83 between the glass opening 10 and the glass 9, and the flames pass through this gap 83 to communicate between the inside and outside of the room (see Figure 18(a)). In addition, the surface of the joint frame 7 (joint cover 8a) exposed to the flames is severely damaged. Furthermore, the occurrence of a gap 83 between the glass opening 10 and the glass 9 accelerates the thermal expansion of the joint frame 7, and as the expanded joint frame 7 comes into contact with the upper frame 1, the joint frame 7 deforms into a U-shape as shown in Figure 18(b).As a result of this deformation, the glass 9 comes off the joint frame 7, creating a gap 84, through which flames can pass.

[0036] 19 shows another embodiment of the opening device 17 of the present invention. This embodiment is an embodiment in which there are three glass doors 5a, 5b, 5b. In this embodiment, two vertical frames 4, 4 are attached at a distance between the upper frame 1 and the lower frame 2, and an interior glass door 5b is arranged between the interior sides of the left and right vertical frames 4, 4 and the left and right vertical frames 3, 3, and an exterior glass door 5a is arranged between the exterior sides of the left and right vertical frames 4, 4. The indoor glass door 5b has the same structure as that of the previous embodiment. As shown in Figure 20, the exterior glass door 5a has glass 9, a lower frame 6 that holds the lower edge of the glass 9, joint frames 7, 7 that hold the left and right edges of the glass 9, respectively, and a sway stopper 66 attached to the upper edge of the glass 9.

[0037] As described above, this opening device 17 comprises an upper frame 1, a lower frame 2, left and right vertical frames 3, 3, a vertical rib 4, an exterior glass door 5a, and an interior glass door 5b. The vertical rib 4 is attached between the upper frame 1 and the lower frame 2 at a midpoint in the left-right direction, and the door-front edges of the exterior glass door 5a and the interior glass door 5b are swallowed up by the vertical frames 3, 3, and the joint side edges can be freely fixed to the vertical rib 4 (see Figure 4), making it easy to attach and fix the exterior glass door 5a and the interior glass door 5b, improving workability. The exterior glass door 5a and the interior glass door 5b have L-shaped frames (lower frame 6 and joint frame 7) that hold the lower edge of the glass 9 and the joint side edge (see Figures 13 and 14-4), making it easy to assemble the glass doors 5a and 5b and ensuring sufficient strength. This opening device 17 has covers (outdoor joint cover 8a, indoor joint cover 8b) that straddle and hide the joint side edges (joint frame 7) of the vertical frame 4 and the glass doors 5a, 5b (see Figure 4), so the joint side edges of the vertical frame 4 and the glass doors 5a, 5b are not exposed to the outside, resulting in good design.

[0038] This opening device 17 comprises glass 9 and frames (bottom frame 6, joint frame 7) that hold the edges of the glass 9, the frames 6, 7 have a glass opening 10, and thermal expansion materials 11, 11 are provided between the glass 9 and the opposing inner surfaces of the glass opening 10, and the glass 9 is held in the glass opening 10 by the thermal expansion materials 11, 11 (see Figures 3, 4), which makes it easy to install the glass 9 and improves workability. Moreover, in the event of a fire, the thermal expansion materials 11, 11 expand, making it difficult for the glass 9 to come out of the glass opening 10 and preventing flames from communicating between the frames 6, 7 and the glass 9. By previously adhering the thermal expansion material 11, 11 to the inside surface of the glass opening 10 or the visible surface of the glass 9 (see Figures 13 and 15), the glass 9 can be fixed to the glass opening 10 simply by inserting it into the glass opening 10, thereby improving the ease of assembly of the door.

[0039] This opening device 17 comprises exterior and interior doors (exterior glass door 5a, interior glass door 5b) arranged in a sliding configuration and a bottom frame 2, and the bottom frame 2 has a running portion (groove) 12a for the exterior door 5a and a running portion (groove) 12c for the interior door 5b, and the running portion 12a of the exterior door 5a is blocked by a batten 13a on the door end side relative to the closed position of the exterior door 5a, and the running portion 12c of the interior door 5b is blocked by a batten 13b on the door end side relative to the closed position of the interior door 5b (see Figure 4), so that the battens 13a, 13b can easily restrict the movement of the exterior and interior doors 5a, 5b arranged in a sliding configuration, making it easy to install. Furthermore, since the running sections 12a, 12c of the doors 5a, 5b of the bottom frame 2 are covered with the battens 13a, 13b, dirt does not accumulate on the running sections 12a, 12c, making them easy to clean. This opening device 17 comprises left and right vertical frames 3, 3, which have grooves 55a, 55c that open on the inner periphery to the outside and inside of the room, and one of the vertical frames 3 has the outside groove 55a to accommodate the door tip of the outside door 5a and the inside groove 55c to seal with a batten 45a, while the other vertical frame 3 has the inside groove 55c to accommodate the door tip of the inside door 5b and the outside groove 55a to seal with a batten 45b (see Figure 4), further improving workability.

[0040] This opening device 17 comprises sliding doors on the outside and inside of the room (outside glass door 5a, inside glass door 5b) and fixing means 14 for fixing the doors 5a and 5b so that they do not move.The fixing means 14 is provided on the outside door 5a and the inside door 5b (see Figure 4), respectively, which makes it easy to install and fix the doors 5a and 5b, improving workability. The fixing means are hidden by the covers (outdoor joint cover 8a, indoor joint cover 8b), improving the design. The covers 8a and 8b are provided over the entire length of the joint between the doors 5a and 5b (see Figs. 14-9 and 14-10), which further improves the design. The fixing means 14 is provided on both the outdoor and indoor sides of the door joint (see Figure 4), so that the outdoor door 5a and the indoor door 5b can be fixed individually, making it easy to use. The fixing means 14 engages the joints of the inner and outer doors 5a, 5b with the vertical frame 4 erected between the upper and lower frames 1, 2, and covers 8a, 8b are attached to the vertical frame 4 from both the outside and inside of the room (see Figure 4).By attaching the covers 8a, 8b, the doors 5a, 5b can be easily fixed, further improving workability. The covers 8a and 8b can be attached and detached by sliding them up and down (see FIG. 14-9), which makes it easy to attach and detach the covers 8a and 8b, further improving workability.

[0041] The present invention is not limited to the above-described embodiments. The cross-sectional shape and materials of the sill and batten can be modified as needed. The structure of the exterior and interior doors can be modified as needed, and the glass does not necessarily have to be fire-resistant glass. The glass may be held in place by a standard seal bead at the glass opening of the frame, and in that case, a thermal expansion material may or may not be present within the glass opening. The exterior and interior doors do not necessarily have to be uniform in size; the left and right dimensions may be different. The present invention is not limited to interior windows installed on the interior side of curtain walls, etc., but can also be applied to windows installed in openings facing the exterior.
