DETAILED DESCRIPTION OF THE INVENTION

[0009] The embodiment will be described with reference to the drawings, using an example of a sliding window installed on the interior side of a building opening.

[0010] -Overall composition- As shown in Figures 1 and 2, the window of this embodiment is the indoor side of an outdoor window A placed in an opening in a building, and is equipped with a frame material 1 fixed to the inner surface of the opening, for example the inner surface of a wooden frame member B, and inner and outer shoji screens 2,2 that are arranged to slide freely around the inner periphery of the frame material 1.

[0011] -First embodiment- (Frame material) The frame material 1 of this embodiment has an upper frame material 11, a lower frame material 12, and left and right vertical frame materials 13, 13. The upper frame member 11, the lower frame member 12 and the left and right vertical frame members 13, 13 are each formed by combining multiple long members made of a metal material such as stainless steel.

[0012] As shown in Figure 3, the upper frame material 11 as a whole has a fixed portion 11a fixed to the upper inner surface of the opening, and guide portions 11b, 11c formed by three visible wall portions 111b, 112b, 114b extending downward from the inner surface of the fixed portion 11a.

[0013] The upper frame member 11 is composed of two L-shaped long members 111 and 112 that form the indoor side, and a flat long member 113 and an L-shaped long member 114 that form the outdoor side.

[0014] The two L-shaped elongated members 111, 112 that form the indoor side of the upper frame member 11 each have a concealed wall portion 111a, 112a and an oblique wall portion 111b, 112b that extends downward from the outdoor end of the concealed wall portion 111a, 112a.

[0015] Of the two L-shaped elongated members 111, 112, the projected wall portion 111a of the L-shaped elongated member 111 stacked on the inner periphery is formed with a smaller projected dimension than the projected wall portion 112a of the L-shaped elongated member 112 stacked on the outer periphery. The two L-shaped elongated members 111, 112 are stacked one on top of the other with their projected wall portions 111a, 112a aligned with their indoor side edges and arranged along the upper inner circumferential surface of the opening (the lower surface of the upper frame member B), and the stacked projected wall portions 111a, 112a are fixed to the upper inner circumferential surface of the opening by fixing means b1 such as screws.

[0016] The two L-shaped elongated members 111, 112 fixed to the upper inner peripheral surface of the opening have the lower end positions of the visible wall portions 111b, 112b aligned, and both visible wall portions 111b, 112b cover the upper edge of the inner shoji screen 2 from inside and outside the room, forming a guide portion 11b that guides the inner shoji screen 2.

[0017] The flat elongated member 113 that forms the outdoor side of the upper frame material 11 has a projected wall portion 113a, and the L-shaped elongated member 114 has a projected wall portion 114a and a projected wall portion 114b that extends downward from the indoor side end of the projected wall portion 114a.

[0018] The projected wall portion 114a of the L-shaped elongated member 114 that forms the outdoor side of the upper frame material 11 is positioned on the inner periphery of the flat elongated member 113 and is formed with a projected dimension that is smaller than that of the projected wall portion 113a. The L-shaped elongated member 114 and the flat elongated member 113 are stacked one on top of the other with the exterior side edges of the projected wall portions 114a, 113a aligned and arranged along the upper inner circumferential surface of the opening (the lower surface of the upper frame member B), and the stacked projected wall portions 114a, 113a are fixed to the upper inner circumferential surface of the opening by fixing means b1 such as screws.

[0019] The lower end position of the visible wall portion 114b of the L-shaped elongated member 114 fixed to the upper inner surface of the opening coincides with the lower end position of the visible wall portion 112b of the other L-shaped elongated member 112 that forms the interior side of the upper frame material 11, and both visible wall portions 114b, 112b cover the upper edge of the outer shoji screen 2 from both the inside and outside of the room, forming a guide portion 11c that guides the outer shoji screen 2.

[0020] As shown in Figure 3, the lower frame material 12 has basically the same configuration as the upper frame material 11, except that its visible dimensions are smaller than those of the upper frame material 11, and overall has a fixed portion 12a fixed to the upper inner surface of the opening, and guide portions 12b, 12c formed by three visible wall portions 121b, 122b, 124b extending upward from the inner surface of the fixed portion 12a.

[0021] The lower frame member 12 is composed of two L-shaped elongated members 121 and 122 that form the indoor side, and a flat elongated member 123 and an L-shaped elongated member 124 that form the outdoor side.

[0022] The two L-shaped elongated members 121, 122 that form the indoor side of the lower frame material 12 each have a concealed wall portion 121a, 122a and an oblique wall portion 121b, 122b that extends upward from the outdoor end of the concealed wall portion 121a, 122a.

[0023] The projected wall portion 121a of the L-shaped elongated member 121 stacked on the inner periphery of the two L-shaped elongated members 121, 122 is formed with a projected dimension smaller than the projected wall portion 122a of the L-shaped elongated member 122 stacked on the outer periphery. The two L-shaped elongated members 121, 122 are stacked one on top of the other with their projected wall portions 121a, 122a aligned with their indoor side edges and arranged along the lower inner circumferential surface of the opening (the upper surface of the lower frame member B), and the stacked projected wall portions 121a, 122a are fixed to the lower inner circumferential surface of the opening by fixing means b2 such as screws.

[0024] The two L-shaped elongated members 121, 122 fixed to the lower inner peripheral surface of the opening have the upper end positions of the visible wall portions 121b, 122b aligned, and both visible wall portions 121b, 122b cover the lower edge of the inner shoji screen 2 from inside and outside the room, forming a guide portion 12b that guides the inner shoji screen 2.

[0025] The flat elongated member 123 that forms the outdoor side of the lower frame material 12 has a projected wall portion 123a, and the L-shaped elongated member 124 has a projected wall portion 124a and a projected wall portion 124b that extends downward from the indoor side end of the projected wall portion 124a.

[0026] The projected wall portion 124a of the L-shaped elongated member 124 that forms the outdoor side of the lower frame member 12 is arranged on the inner periphery side of the flat elongated member 123 and is formed with a projected dimension smaller than that of the projected wall portion 123a. The L-shaped elongated member 124 and the flat elongated member 123 are stacked one on top of the other with their projected wall portions 124a, 123a aligned with their outdoor edges and arranged along the lower inner circumferential surface of the opening (the upper surface of the lower frame member B), and the stacked projected wall portions 124a, 123a are fixed to the lower inner circumferential surface of the opening by fixing means b2 such as screws.

[0027] The upper end position of the visible wall portion 124b of the L-shaped elongated member 124 fixed to the lower inner surface of the opening coincides with the upper end position of the visible wall portion 122b of the other L-shaped elongated member 122 that forms the indoor side of the lower frame material 12, and both visible wall portions 124b, 122b cover the lower edge of the outer shoji screen 2 from both the indoor and outdoor sides, forming a guide portion 12c that guides the outer shoji screen 2.

[0028] As shown in Figure 4, the vertical frame member 13 is composed of a set of L-shaped elongated members, namely, an L-shaped elongated member 131 that forms the indoor side and an L-shaped elongated member 132 that forms the outdoor side.

[0029] The L-shaped elongated member 131 that forms the indoor side of the vertical frame material 13 has a projected wall portion 131a and a visible wall portion 131b that extends inward from the outdoor end of the projected wall portion 131a, and the L-shaped elongated member 132 that forms the outdoor side has a projected wall portion 132a and a visible wall portion 132b that extends inward from the indoor end of the projected wall portion 132a.

[0030] The two L-shaped elongated members 131, 132 are arranged with their facing wall portions 131b, 132b facing each other, and their facing wall portions 131a, 132a are positioned on the vertical inner surface of the opening (the inner surfaces of the left and right frame members B) and fixed to the vertical inner surface of the opening by fixing means b3 such as screws.

[0031] The two L-shaped elongated members 131, 132 fixed to the vertical inner peripheral surface of the opening have the inner peripheral end positions of the visible wall portions 131b, 132b aligned, and the two visible wall portions 131b, 132b form a fitting portion 13a on the vertical inner peripheral surface of the opening where the vertical edges of the inner and outer shoji screens 2, 2 fit. When the inner and outer shoji screens 2, 2 are closed, the vertical edges of the inner and outer shoji screens 2, 2 directly contact the vertical inner peripheral surface of the opening and are stored in the storage section 13a, and both visible wall sections 131b, 132b cover the vertical edges of the inner and outer shoji screens 2, 2 from inside and outside the room.

[0032] The upper frame material 11, the lower frame material 12, and the left and right vertical frame materials 13, 13 are not assembled around all four sides with fasteners such as screws, but as shown in Figure 5, they are each fixed to the inner surface of the opening, thereby forming a frame as a whole.

[0033] Specifically, the vertical frame member 13 on the left side of the frame is positioned so that its fitting portion 13a is continuous with the outdoor-side guide portion 11c of the upper frame member 11 and the outdoor-side guide portion 12c of the lower frame member 12, and the vertical frame member 13 on the right side of the frame is positioned so that its fitting portion 13a is continuous with the indoor-side guide portion 11b of the upper frame member 11 and the indoor-side guide portion 12b of the lower frame member 12, and each is fixed to the inner surface of the opening.

[0034] In addition, the upper end portions of the visible wall sections 131b and 132b of the left vertical frame member 13 have been removed from the outside of the upper frame member 11 by an amount sufficient to accommodate the two visible wall sections 112b and 114b, and the lower end portions of the visible wall sections 131b and 132b have been removed from the outside of the lower frame member 12 by an amount sufficient to accommodate the two visible wall sections 122b and 124b. Similarly, the upper ends of the visible wall sections 131b, 132b of the right vertical frame member 13 have been removed from the interior side of the upper frame member 11 by an amount sufficient to accommodate the two visible wall sections 111b, 112b, and the lower ends of the visible wall sections 131b, 132b have been removed from the interior side of the lower frame member 12 by an amount sufficient to accommodate the two visible wall sections 121b, 122b, preventing interference between the visible wall sections and allowing the upper and lower frame members and the left and right vertical frame members to fit smoothly together.

[0035] (Shoji screen) As shown in Figs. 3 and 4, the inner and outer shutters 2 of this embodiment are made only of fireproof glass plates such as heat-resistant crystallized glass, and do not have frame materials such as aluminum. The inner and outer shoji screens 2, 2 are attached by means of a kendon to guide portions 11b, 11c, 12b, 12c formed on the upper frame material 11 and the lower frame material 12, and are arranged so as to be freely slidable.

[0036] When the inner and outer shoji screens 2, 2 are closed, the door edges abut the vertical inner peripheral surface of the opening, and the upper and lower edges are covered from inside and outside the room by the visible wall portions of the upper frame material 11 and the lower frame material 12, and the vertical edge on the door edge side is covered by the visible wall portions 131b, 132b of the vertical frame material 13.

[0037] (Effects of the window of this embodiment) As described above, the window of this embodiment can be equipped with fire prevention equipment with a simple structure by fixing long frame material to the inner periphery of the opening to form a frame and forming a shoji screen using fire-resistant glass panels.

[0038] Furthermore, in the window of this embodiment, the indoor and outdoor surfaces of the outer periphery of the shoji screen, which is made of fire-resistant glass panels, are covered with frame material, making it difficult for a flame path to form inside or outside the room, and fire prevention performance can be maintained. Furthermore, the vertical frame material does not have a part where the edge of the shoji screen abuts, and the edge of the shoji screen abuts directly against the inner surface of the opening, so the shoji screen can be moved by deformation of the vertical frame material due to heat during a fire, reducing the risk of gaps occurring between the shoji screen and the frame material and further maintaining fire resistance. Furthermore, the left vertical frame material 13 is formed with only a fitting section 13a that fits the leading edge of the outer shoji screen 2, and the right vertical frame material 13 is formed with only a fitting section 13a that fits the leading edge of the inner shoji screen 2, so that the simple structure improves workability while maintaining fire resistance. Furthermore, the upper frame material 11, the lower frame material 12, and the left and right vertical frame materials 13 are formed from L-shaped members, making manufacturing easy. Also, the left vertical frame material 13 is an L-shaped member that forms only the fitting portion 13a that fits the door edge of the outer shoji screen 2, and the right vertical frame material 13 is an L-shaped member that forms only the fitting portion 13a that fits the inner shoji screen 2, so material costs can be reduced.

[0039] -Second embodiment- (Frame material) The frame material 1 of this embodiment has an upper frame material 51, a lower frame material 52, and left and right vertical frame materials 53, 53, each made of a metal material such as stainless steel or aluminum alloy. Note that, with regard to the window of this embodiment, the description of the same configuration as the window of the first embodiment will be omitted.

[0040] As shown in FIG. 6(a), the upper frame member 51 has a concealed wall portion 51a fixed to the upper inner peripheral surface B1 of the opening, an indoor wall portion 51b and an outdoor wall portion 51c extending downward from the indoor end and outdoor end of the concealed wall portion 51a, and three visible wall portions 51d, 51e, 51f extending downward from the inner peripheral surface of the concealed wall portion 51a, and the three visible wall portions 51d, 51e, 51f form upper guide portions 51g, 51g that guide the upper edges of the inner and outer shoji screens 2, 2.

[0041] The upper frame member 51 has a projected wall portion 51a disposed on the upper inner peripheral surface B1 of the opening with a resin spacer 512 sandwiched therebetween, and is fixed at the bottoms of the upper guide portions 51g, 51g by fixing means b1 such as screws.

[0042] The upper frame material 51 has multiple ribs 51i extending longitudinally on the outer peripheral surface of the projected wall portion 51a, and heated foam materials f, f that expand due to heat during a fire are arranged at appropriate positions between the outer peripheral surface of the projected wall portion 51a and the resin spacer 512.

[0043] As shown in Figure 6(a), the lower frame material 52 has a projected wall portion 52a fixed to the lower inner surface B2 of the opening, and inner and outer lower rails 52b, 52b extending upward from the inner surface of the projected wall portion 52a. The upper ends of the inner and outer lower rails 52b, 52b are bent horizontally to form wide door roller mounting portions 52c, 52c in the projection direction.

[0044] The lower frame material 52 has a projected wall portion 52a arranged on the lower inner peripheral surface B2 of the opening with a resin spacer 522 sandwiched therebetween, and is fixed between the inner and outer lower rails 52b, 52b by fixing means b2 such as screws.

[0045] The outer peripheral surface of the projected wall portion 52a of the lower frame material 52 is provided with a plurality of ribs 52i extending in the longitudinal direction, and heated foam materials f, f that expand due to heat during a fire are arranged at appropriate positions between the outer peripheral surface of the projected wall portion 52a and the resin spacer 522. As shown in FIG. 6(b), the lower frame member 52 may be provided with a cover member 52d on the upper surface of the projecting wall portion 52a between the inner and outer lower rails 52b, 52b so as to cover the head of the fixing means b2.

[0046] As shown in Figures 7(a) and (b), the vertical frame member 53 has an outer peripheral member 531 made of a metal material such as an aluminum alloy and fixed to the vertical inner peripheral surface B3 of the opening, and an inner peripheral member 532 made of a metal material such as stainless steel or an aluminum alloy and attached to the inner periphery of the outer peripheral member 531. The vertical frame member 53 can be rotated 180 degrees around the vertical axis to serve as both the left and right vertical frames.

[0047] The outer peripheral member 531 of the vertical frame material 53 has a projected wall portion 531a fixed to the vertical inner peripheral surface B3 of the opening, and projected wall portions 531b, 531b extending inward from the indoor end and outdoor end of the projected wall portion 531a.

[0048] The inner peripheral member 532 of the vertical frame material 53 has an indoor-side visible wall 532a, an outdoor-side visible wall 532b, an indoor-side visible wall 532c extending from the inner peripheral end of the indoor-side visible wall 532a toward the outside of the room, an outdoor-side visible wall 532d extending from the inner peripheral end of the outdoor-side visible wall 532b toward the room, a shoji receiving room inner wall 532e extending from the outside of the indoor-side visible wall 532c toward the outer periphery, a shoji receiving room outer wall 532f extending from the indoor-side of the outdoor visible wall 532d toward the outer periphery, and a bottom wall 532g connecting the shoji receiving room inner wall 532e and the shoji receiving room outer wall 532f.

[0049] The vertical frame member 53 is formed by inserting an inner peripheral member 532 between the inner and outer visible wall portions 531b of the outer peripheral member 531, abutting the bottom wall 532g of the inner peripheral member 532 against the visible wall portion 531a of the outer peripheral member 531, and connecting them with fixing means b32 such as screws.

[0050] The vertical frame material 53 has a fitting portion 53a formed by the shoji receiving room inner wall 532e, the shoji receiving room outer wall 532f, and the bottom wall 532g of the inner peripheral member 532, which receives the leading edge of the shoji 2 when closed, and hollow portions 53b are formed on both sides of the fitting portion 53a in the forward direction.

[0051] The fitting portion 53a formed in the vertical frame member 53 is formed biased to one side in the projection direction by making the projection width dimensions of the indoor projection wall 532c and the outdoor projection wall 532d of the inner peripheral member 532 different, and the vertical frame member 53 is arranged so that the positions of the fitting portions 53a of the vertical frame members 53 arranged on the left and right are different in the projection direction by inverting the vertical frame member 53 around the vertical axis.

[0052] Specifically, the left vertical frame member 53 is formed with only a fitting portion 53a that accommodates the leading edge of the outer shoji screen 2 that abuts against the vertical frame member 53 when closed, and the right vertical frame member 53 is arranged so that it only has a fitting portion 53a that accommodates the leading edge of the inner shoji screen 2 that abuts against the right vertical frame member 53 when closed.

[0053] The vertical frame member 53 is arranged such that the projected wall portion 531a of the outer peripheral member 531 is disposed on the vertical inner peripheral surface B3 of the opening with a resin spacer 535 sandwiched therebetween, and is fixed by fixing means b3 such as screws. The outer peripheral surface of the projected wall portion 531a of the peripheral member 531 of the vertical frame material 53 is provided with a plurality of ribs 531i extending in the longitudinal direction, and heated foam materials f, f that expand due to heat during a fire are arranged at appropriate positions between the outer peripheral surface of the projected wall portion 531a and the resin spacer 535.

[0054] The vertical frame member 53 may be formed by an outer peripheral member 531 made of a metal material such as an aluminum alloy, and two inner peripheral members 533 and 534 made of a metal material such as an aluminum alloy.

[0055] For example, as shown in FIG. 7(c), the vertical frame member 53 is configured such that the outer peripheral member 531 is made up of a concealed wall portion 531a fixed to the vertical inner peripheral surface of the opening B, an indoor side wall portion (visible wall portion) 531b extending in the inner peripheral direction from the indoor end of the concealed wall portion 531a, an outdoor side wall portion (visible wall portion) 531c extending in the inner peripheral direction from the outdoor end of the concealed wall portion 531a, and an obstacle portion (visible wall portion) 531b extending in the inner peripheral direction from the inner peripheral surface of the concealed wall portion 531a. It may be formed from a child receiving room inner wall portion 531d and a shoji receiving room outer wall portion 531e, and the inner peripheral members 533, 534 may each be formed from a flat plate-shaped member, and the inner peripheral members 533, 534 may be attached between the indoor side wall portion 531b of the outer peripheral member 531 and the shoji receiving room inner wall portion 531d, and between the outdoor side wall portion 531c of the outer peripheral member 531 and the shoji receiving room outer wall portion 531e, respectively.

[0056] In this case, locking portions 531f may be formed on the inner peripheral ends of the indoor wall portion 531b, the shoji receiving room inner wall portion 531d, the outdoor wall portion 531c, and the shoji receiving room outer wall portion 531e of the outer peripheral member 531, and the locking portions 533a, 534a formed on both ends of the inner peripheral members 533, 534 may be locked to integrate the two.

[0057] (Shoji screen) As shown in Figures 6 and 7, the inner and outer shutters 2, 2 are formed by attaching a door roller mounting material 22 to the lower edge of a fireproof glass plate 20 made of, for example, heat-resistant crystallized glass. The upper edges of the inner and outer shoji screens 2, 2 are guided by the upper guide portion 51g formed on the upper frame material 51, and the door rollers 22a of the door roller mounting material 22 are placed on the door roller mounting portions 52c, 52c of the inner and outer lower rails 52b, 52b of the lower frame material 52, and are arranged so that they can slide freely.

[0058] In addition, the inner and outer shoji screens 2, 2 may be fitted with an upper edge member 21 made of a resin material or the like at their upper edges so that it is guided by the upper guide portion 51g of the upper frame material 51, thereby stabilizing the sliding movement of the shoji screen 2 and suppressing noise caused by the glass panel coming into contact with the metal frame material. In addition, the inner shoji screen 2 may have a handle 2a attached to the interior side of the fireproof glass panel 20 by adhesive or other fixing means.

[0059] When closed, the upper edges of the outer shoji screens 2, 2 are covered from inside and outside the room by the visible wall portions 51d, 51e, 51f of the upper frame material 51, and the left and right vertical edges on the door ends are positioned within the fitting portions 53a of the vertical frame materials 13, 13, respectively.

[0060] (Effects of the window of this embodiment) The window of this embodiment has a simple structure that allows for fire prevention equipment to be installed by fixing a long frame material to the inner periphery of the opening to form a frame and forming a shoji screen using fire-resistant glass panels.

[0061] Furthermore, in the window of this embodiment, the indoor and outdoor surfaces of the outer periphery of the shoji screen, which is made of fire-resistant glass panels, are covered with frame material, making it difficult for a flame path to form inside or outside the room, and fire prevention performance can be maintained.

[0062] In addition, the left vertical frame member 53 only has a fitting portion 53a formed to fit the leading edge of the outer shoji screen 2, and the right vertical frame member 53 only has a fitting portion 53a formed to fit the leading edge of the inner shoji screen 2, and the gap between the vertical frame member 53 and the inner and outer shoji screens 2 is covered with an inner peripheral member, and hollow portions 53b, 53b are formed on both sides of the fitting portion 53a of the left and right vertical frame members 53 in the forward direction, so that in the event of a fire, flames are less likely to pass through, the fitting portion 53a that fits the leading edges of the inner and outer shoji screens 2, 2 can be protected, and fire resistance can be improved.

[0063] Furthermore, the inner and outer lower rails 52b, 52b that guide the inner and outer shoji screens 2, 2 have wide portions (roller mounting portions 52c, 52c) that are formed wide in the projection direction, and these wide portions mount the rollers 22a, 22a inside and below the roller mounting materials 22 of the inner and outer shoji screens 2, 2.This prevents the inner and outer shoji screens 2, 2 from shifting in the projection direction and creating gaps at the joints, and also keeps the gaps between the inner and outer lower rails 52b, 52b and the roller mounting materials 22 small, improving fire prevention performance.

[0064] -Third embodiment- The window of this embodiment comprises a frame material 1 arranged on the inner periphery of the opening B, and multiple (in this example, three) shoji screens 2 guided by the frame material 1 and arranged so as to be able to slide freely in the left-right direction. The frame member 1 has an upper frame member 71, a lower frame member 72, and left and right vertical frame members 73, 73, each made of a metal material such as an aluminum alloy. Note that, with regard to the window of this embodiment, explanation of the same configuration as the window of the first and second embodiments will be omitted.

[0065] As shown in FIG. 8, the upper frame material 71 has a plurality of upper frame members 711 arranged on the upper inner circumferential surface B1 of the opening. As shown in Figures 9(a) and (b), the upper frame member 711 is a long member with an approximately L-shaped cross section, having a concealed wall 711a fixed to the upper inner surface B1 of the opening, and a concealed wall 711b extending in the inner circumferential direction (downward) from one end of the concealed wall 711a facing indoors and outdoors.

[0066] The upper frame member 711 has a plurality of elongated holes 711c formed in a projecting wall 711a, and is fixed to an upper inner peripheral surface B1 of the opening with fixing means b1 such as screws. The upper frame material 71 is formed by arranging multiple upper frame members 711 adjacent to each other in the forward direction, so that an upper guide portion 71a that guides the shoji screen 2 is formed between the visible walls 711b of adjacent upper frame members 711.

[0067] As shown in Figures 8 and 9(a), the lower frame material 72 has a core material 722 made of aluminum alloy, wood, resin material, etc., and two rail shapes 721 made of metal material such as aluminum alloy attached to the left and right sides of the core material 722, and multiple lower rail portions 721d are provided on the upper surface of the lower frame body, which has an approximately rectangular cross-section overall.

[0068] As shown in Figure 9(c), the rail profile 721 of the lower frame material 72 has a concealed wall 721a that runs along the upper surface of the core material 722, a visible wall 721b that runs along the indoor or outdoor side of the core material 722, a bottom wall 721c that extends from the lower end of the visible wall 721b along the lower surface of the core material 722, and multiple lower rail portions 721d, 721d that extend upward from the upper surface of the concealed wall 721a, and a screw hole 721e is formed between the two lower rail portions 721d, 721d of the concealed wall 721a. The lower rail portion 721d of the rail member 721 is provided at its upper portion with a roller mounting portion 721f which is formed to be wider in the projection direction.

[0069] The lower frame material 72 is formed by inserting the left and right edges of the core material 722 between the projected wall 721a and the bottom wall 721c of the rail profile 721, placing it on the lower inner surface B2 of the opening, and fixing it between the two lower rail portions 721d, 721d of the projected wall 721a by fixing means b2 such as screws.

[0070] In addition, gypsum boards C, etc. may be arranged on the indoor and outdoor sides of the lower frame material 72 fixed to the opening B so that the upper surface of the roller mounting portion 721f of the lower rail portion 721d is flush with the upper end surface of the gypsum board C. By making the upper end of the roller mounting portion 721f of the lower rail portion 721d of the lower frame material 72 flush with the upper end surface of the gypsum board C, it is possible to achieve effects such as improving the design.

[0071] As shown in Figures 8 and 10(a), the vertical frame member 73 has a main vertical frame member 731 made of a metal material such as an aluminum alloy, and a secondary vertical frame member 732 made of a metal material such as an aluminum alloy, and both members are connected so that the length can be adjusted freely.

[0072] As shown in FIG. 10(b), the main vertical frame member 731 is a long member with a generally U-shaped cross section that has a concealed wall 731a and concealed wall portions 731b, 731b extending inward from the indoor and outdoor ends of the concealed wall 731a.

[0073] The main vertical frame member 731 has its upper end abutting or close to the upper inner peripheral surface B1 of the opening, and the projected wall 731a is positioned along the vertical inner peripheral surface B3 of the opening, and the projected wall 731a is fixed to the vertical inner peripheral surface B3 of the opening by fixing means b3 such as screws.

[0074] As shown in Figures 10(b) and (c), the secondary vertical frame member 732 is a member with an approximately U-shaped cross section having a concealed wall 732a and concealed wall portions 732b, 732b extending inward from the indoor end and outdoor end of the concealed wall 732a.

[0075] The sub-vertical frame material 732 is arranged with its lower end abutting or close to the lower inner peripheral surface B2 of the opening (or a plasterboard or the like arranged on the lower inner peripheral surface B2) and with the projected wall 732a aligned along the vertical inner peripheral surface B3 of the opening, and is fixed by gluing or the like with a resin spacer 734 sandwiched between the projected wall 732a and the vertical inner peripheral surface B3 of the opening.

[0076] The vertical frame member 73 placed in the opening has the lower part of the main vertical frame member 731 overlapping with the upper part of the secondary vertical frame member 732, and at the overlapping part, the indoor side walls and the outdoor side walls of both members are connected to each other by fixing means b4 such as screws.

[0077] The facing wall portion 731b of the main vertical frame member 731 and the facing wall portion 732b of the secondary vertical frame member 732 have screw holes formed in them to connect the two members, but the screw holes in the facing wall portion 731b of the main vertical frame member 731 or the facing wall portion 732b of the secondary vertical frame member 732 are formed as elongated holes, and by misaligning the main vertical frame member 731 and the secondary vertical frame member 732 at the connection point between them, thermal expansion of the vertical frame member 73 can be absorbed when the vertical frame member 73 expands due to heat.

[0078] In addition, gypsum boards C or the like may be placed on the indoor and outdoor sides of the vertical frame material 73 fixed to the opening B.

[0079] (Shoji screen) As shown in Figs. 8 to 10, the plurality of shoji screens 2 of this embodiment are formed by attaching a door roller mounting member 22 to the lower edge of a fireproof glass plate 20 made of heat-resistant crystallized glass or the like. The upper edge of the shoji screen 2 is guided by an upper guide portion 71a formed on the upper frame material 71, and the door roller 22a of the door roller mounting material 22 is guided by a lower rail portion 721d of the lower frame material 72, so that it is arranged to slide freely. In addition, the shoji screen 2 may have an upper edge member 21 made of a resin material or the like attached to the upper edge, and be guided by the upper guide portion 71a of the upper frame material 71.

[0080] Of the multiple shoji screens 2, the shoji screens 2 located at the left and right ends may be fitted with a handle 2a, and by providing the handle 2a, the shoji screens 2 can be opened and closed by holding the handle 2a.

[0081] In addition, the shoji screens 2 may be provided with an engagement portion 2b for interlocking adjacent shoji screens 2 with each other. For example, as shown in Figure 10(d), the shoji screen 2 may have an engagement portion 2b formed by attaching a flat block-shaped member made of a resin material to the lower portions of the left and right ends of the surface facing the adjacent shoji screen 2 using fixing means b such as screws. By moving the left and right end shoji screens 2 left and right, the engaging portions 2b, 2b of adjacent shoji screens 2, 2 engage with each other, and the adjacent shoji screens 2 can be linked together.

[0082] When closed, the upper edges of the multiple shoji screens 2 are each covered from both inside and outside the room by the visible walls 711b of the upper frame members 711 that make up the upper frame material 71, and the vertical edges of the shoji screens 2 located at the left and right ends abut or are close to the inner surface of the vertical frame material 73, and are positioned between the visible wall portions 731b on the inside and outside of the room of the main vertical frame member 731 of the vertical frame material 73, so that they are covered from both inside and outside the room.

[0083] (Effects of the window of this embodiment) The window of this embodiment has a simple structure that allows for fire prevention equipment to be installed by fixing a long frame material to the inner periphery of the opening to form a frame and forming a shoji screen using fire-resistant glass panels.

[0084] Furthermore, in the window of this embodiment, the indoor and outdoor surfaces of the outer periphery of the shoji screen, which is made of fire-resistant glass panels, are covered with frame material, making it difficult for a flame path to form inside or outside the room, and fire prevention performance can be maintained.

[0085] Furthermore, the lower rail portion 721d that guides the shoji screen 2 has a wide portion (roller mounting portion 721f) that is formed wide in the projection direction, and this wide portion mounts the roller 22a inside the lower part of the roller mounting material 22 of the shoji screen 2, so that the shoji screen 2 is prevented from shifting in the projection direction and creating a gap at the joint, and the gap between the lower rail portion 721d and the roller mounting material 22 can be kept small, thereby improving fire prevention performance. Furthermore, the upper frame material 71 is formed from a plurality of L-shaped members, and the lower frame material 72 is formed by fixing rail shapes 721 of the same shape to a core material, so that the members can be used interchangeably, reducing member costs.

[0086] -Fourth embodiment- The window of this embodiment comprises a frame material 1 arranged on the inner periphery of the opening B, and multiple (in this example, three) shoji screens 2 guided by the frame material 1 and arranged so as to be able to slide freely in the left-right direction. The frame member 1 has an upper frame member 91, a lower frame member 92, and left and right vertical frame members 93, 93, each made of a metal material such as an aluminum alloy. Note that, with regard to the window of this embodiment, explanations of the same configuration as the windows of the first to third embodiments will be omitted.

[0087] The upper frame material 91 is made of a metal material such as aluminum alloy, and as shown in Figure 11, has a projected wall portion 91a fixed to the upper inner surface B1 of the opening, and four visible wall portions 91b, 91c, 91d, and 91e extending downward from the inner surface of the projected wall portion 91a, and three upper guide portions 91f, 91g, and 91h that guide the upper edges of the shoji screens 2, 2 are formed between the four visible wall portions 91b, 91c, 91d, and 91e.

[0088] The upper frame material 91 is arranged so that the projected wall portion 91a is aligned with the upper inner peripheral surface B1 of the opening, and is fixed by fixing means b1, b1 such as screws at the upper guide portions 91f, 91h on the indoor and outdoor sides.

[0089] The lower frame material 92 is made of a metal material such as an aluminum alloy, and as shown in Figure 11, has a projected wall portion 92a fixed to the lower inner surface B2 of the opening, and an inner rail portion 92b, a middle rail portion 92c, and an outer rail portion 92d extending upward from the inner surface of the projected wall portion 92a. The inner rail portion 92b, the middle rail portion 92c, and the outer rail portion 92d of the lower frame material 92 are formed with a door roller mounting portion at the top that is wide in the projection direction.

[0090] The lower frame material 92 is positioned so that the projected wall portion 92a is aligned with the lower inner surface B2 of the opening, and is fixed between the inner rail portion 92b and the middle rail portion 92c, and between the middle rail portion 92c and the outer rail portion 92d by fixing means b2, b2 such as screws.

[0091] The upper frame material 91 and the lower frame material 92 have multiple ribs extending longitudinally on the outer peripheral surfaces of the projected wall portions 91a, 92a, and are arranged at a distance from the upper inner peripheral surface B1 or the lower inner peripheral surface B2.If necessary, a heated foam material that expands due to heat in the event of a fire may be arranged at an appropriate position between the outer peripheral surfaces of the projected wall portions 91a, 92a and the upper inner peripheral surface B1 or the lower inner peripheral surface B2.

[0092] The vertical frame material 93 has the same configuration on the left and right sides, and includes a main vertical frame material (main frame material) 931 arranged along the longitudinal direction on the vertical inner surface B3 of the opening, a sub-vertical frame material (sub-frame material) 932 connected to the lower end of the main vertical frame material 931 so as to be movable longitudinally, and an inner peripheral member (cover material) 933 engaged with the inner periphery of the main vertical frame material 931. The vertical frame material 93 can be rotated 180 degrees around the vertical axis to serve as both the left and right vertical frames, and is fixed to the vertical inner surface B3 of the opening with its top and bottom abutting or close to the upper inner surface B1 and lower inner surface B2 of the opening.

[0093] As shown in Figures 12(a)(b)(c), 13(a), 14, and 15(a), the main vertical frame member 931 has a projected wall portion 931a and projected wall portions 931b, 931b extending inward from the indoor end and outdoor end of the projected wall portion 931a.

[0094] The main vertical frame member 931 consists of a long main body portion 931A made of a metal material such as aluminum alloy and having a length dimension h931 that is shorter than the height dimension H of the opening B, and a resin cover portion 931B that is provided continuously with the longitudinal end of the main body portion 931A, which in this embodiment is the lower end, and has a length dimension h93 overall that is approximately the same as the height dimension H of the opening B.

[0095] When the vertical frame member 93 is fixed to the opening, the upper end of the main body portion 931A abuts or is close to the upper inner peripheral surface B1, and the lower end of the cover portion 931B abuts or is close to the lower inner peripheral surface B2, so that the projected wall portion 931a is positioned along the vertical inner peripheral surface B3 of the opening, and is fixed by fixing means b3 such as screws.

[0096] The covering portion 931B of the main vertical frame member 931 may have a visible wall portion and an indoor and outdoor visible wall portion, similar to the main body portion 931A, but it is sufficient that it has dimensions and a shape that are at least large enough to cover the sub-vertical frame member 932 when viewed from the inside of the room.

[0097] Furthermore, the means for providing the cover portion 931B continuously with respect to the lower end of the main body portion 931A of the main vertical frame member 931 is not limited, and for example, an insertion portion may be provided in the upper portion of the cover portion 931B so as to follow the inner surface of the lower end of the main body portion 931A, and the insertion portion may be adhered to the inside of the main body portion 931A, etc.

[0098] The main body 931A of the main vertical frame member 931 is provided with an engagement piece 931c that extends inward from the inner surface of the projecting wall portion 931a and then bends to one side, and an engagement piece 931d that protrudes from the inner surface of the projecting wall portion 931b on one side, and both engagement pieces 931c, 931d form an engaged portion with which the inner member (cover material) 933 engages.

[0099] The engagement pieces 931c and 931d of the main body 931A of the main vertical frame member 931 are cut out in the lower region, preventing interference between the engagement pieces 931c and 931d and the sub-vertical frame member 932 when the sub-vertical frame member 932 is connected to the lower inner periphery of the main vertical frame member 931.

[0100] The main vertical frame member 931 has a vertically long slot 931e formed in a facing wall portion 931b that faces the outside of the room when placed in the opening B of the building. The long holes 931e provided in the main vertical frame members 931 may be provided in the facing wall portion 931b on the room side, or may be provided in both facing wall portions 931b.

[0101] The secondary vertical frame member 932 is made of a metal material such as aluminum alloy, and as shown in Figures 12(c), 13(b), 14, and 15(a), is arranged inside the main vertical frame member 931 and has a concealed wall portion 932a that runs along the concealed wall portion 931a of the main vertical frame member 931, and visible wall portions 932b, 932b that extend inward from the indoor and outdoor ends of the concealed wall portion 932a and run along the visible wall portions 931b, 931b of the main vertical frame member 931.

[0102] The secondary vertical frame member 932 has a screw hole 932e formed in the visible wall portion 932b that faces the outside of the room when placed in the opening B of the building, and as can be seen in Figures 13(c) and 14, it is placed inside the main vertical frame member 931, and the long hole 931e formed in the visible wall portion 931b on the outside of the room of the main vertical frame member 931 and the screw hole 932e formed in the visible wall portion 932b on the outside of the room of the secondary vertical frame member 932 are fixed and connected with fixing means b93 such as screws.

[0103] The position of the fixing means b93 in the long hole 931e of the main vertical frame member 931 is adjusted and fixed at a position where the length dimension of the vertical member formed by the main vertical frame member 931 and the secondary vertical frame member 932 is the same as the height dimension H of the opening B, and when the vertical frame member 13 is fixed to the opening, the lower end of the secondary vertical frame member 932 abuts or is close to the lower inner surface B2.

[0104] It is preferable that the lower end position of the sub-vertical frame member 932 of the vertical frame member 93 is the same as the lower end position of the cover portion 931B of the main vertical frame member 931, but depending on design errors and errors in the height dimension H of the opening B, the lower end of the sub-vertical frame member 932 may be connected so that it protrudes from the lower end of the cover portion 931B.

[0105] In addition, the secondary vertical frame member 932 only needs to be attached so that it can move longitudinally relative to the main vertical frame member 931 so that it can absorb the thermal expansion of the main vertical frame member 931 in the event of a fire, and the location at which the secondary vertical frame member 932 is attached is not limited to the lower end of the main vertical frame member 931. Furthermore, the end of the main vertical frame member 931 to which the sub-vertical frame member 932 is attached is not limited to the end face portion of the main vertical frame member 931, but may be an area near the end.

[0106] As shown in Figures 12(a)(b), 14, and 15(b), the inner peripheral member (cover material) 933 has a projected wall portion 933a, visible wall portions 933b, 933b extending outward from the indoor and outdoor ends of the projected wall portion 933a, and engaging claws 933c, 933c provided on the outer peripheral ends of the visible wall portions 933b, 933b.

[0107] The inner peripheral member 933 has a main body 933A made of a metal material such as an aluminum alloy and having a length dimension h933 smaller than the length dimension h93 of the main vertical frame member 931, and a resin end member (cap member) 933B fitted into the upper and lower ends of the main body 933A.

[0108] The end members 933B fitted into the upper and lower ends of the main body 933A protrude by the difference between the dimension h933 of the main body 933A and the dimension h93 of the main vertical frame member 931, and have an overall length dimension approximately the same as the length dimension h13 of the vertical frame member 13.

[0109] The resin end members 933B of the inner circumferential member 933 may be provided at both the upper and lower ends of the main body portion 933A, or may be provided at either the upper or lower end.

[0110] The dimension by which the resin end member 933B protrudes from the end of the main body 933A means the sum of the protrusion amounts of the upper and lower end members 933B fitted into the upper and lower end members of the main body 933A, and if it is provided at either the upper or lower end member, it means the protrusion amount of the end member 933B provided at that end member.

[0111] Furthermore, it is preferable that the overall dimension of the inner peripheral member (cover member) 933, including the end member 933B, be approximately the same length dimension as the length dimension h93 of the main vertical frame member 931, but depending on design errors, etc., it may be shorter than the length dimension h93 of the vertical frame member 13.

[0112] Inner peripheral member (cover member) 933 has notched portions 933f formed by cutting out facing wall portions 933b, 933b from the outer periphery in the lower region of main body portion 933A.

[0113] The inner peripheral member (cover member) 933 is engaged with the inner periphery of the main vertical frame member 931 by engaging the engaging claws 933c, 933c with the engaging pieces 931c, 931d of the main vertical frame member 931 from the inner periphery side. At this time, the inner peripheral member 933 can be placed inside the inner peripheral side of the main vertical frame member 931 without interfering with the sub-vertical frame member 932, since the cutout portion 933f is positioned on the inner peripheral side of the sub-vertical frame member 932 connected to the main vertical frame member 931.

[0114] The vertical frame member 93, which has an inner peripheral member 933 arranged on the inner periphery of the main vertical frame member 931 and the auxiliary vertical frame member 932, has a fitting portion 93a formed on the side in the projection direction where the inner peripheral member 933 is not engaged, for fitting the leading edge of the shoji screen 2, as shown in Figures 12(a) and 16, and is positioned between the upper inner peripheral surface B1 and the lower inner peripheral surface B2 of the opening and fixed to the vertical inner peripheral surface B3.

[0115] The configuration of the shoji screen of this embodiment is the same as that of the shoji screen of the third embodiment, so the appropriate reference numerals are used here and detailed explanations are omitted.

[0116] (Effects of the window of this embodiment) In this embodiment, the window has a metal frame covering the interior and exterior surfaces of the shoji screen, which is made of fire-resistant glass panels, making it difficult for flames to form paths inside and outside the room, thereby maintaining fire resistance.

[0117] In the event of a fire, metal frame materials, particularly the vertical frame material 93 which is formed to be relatively long, are likely to stretch, and this stretching could destroy the fixture; however, in the fixture of this embodiment, the vertical frame material 93 is formed by movably connecting a metal sub-vertical frame material 932 below a metal main vertical frame material 931, so even if the vertical frame material 93 stretches due to the heat of a fire, as shown in Figures 13(d), 17 and 18, the fixing means b93 connecting the main vertical frame material 931 and the sub-vertical frame material 932 shifts within the long hole 931e of the main vertical frame material 931, causing the connecting part to move and absorb the stretched part of the main vertical frame material 931. Therefore, in the event of a fire, it is possible to prevent damage to fixtures due to the vertical frame material 93, which has a large length, stretching, and to prevent communication between the inside and outside of the room.

[0118] Furthermore, the main vertical frame member 931 has a resin cover portion 931B provided at the end of the metal main body portion 931A, which prevents the exposure of the secondary vertical frame member 932 arranged on the inner periphery of the main vertical frame member 931 under normal conditions, and in the event of a fire, it will not melt and prevent the main vertical frame member 931 and secondary vertical frame member 932 from absorbing thermal expansion.

[0119] Furthermore, in the window of this embodiment, the vertical frame material 93 has an inner peripheral member (cover member) 933 arranged on the inner periphery of the main vertical frame material 931, so that the inner periphery of the vertical frame material 93 other than the fitting portion 93a that fits the leading edge of the shoji screen 2 can be protected, and the inner periphery of the vertical frame material 93 where the shoji screen 2 is not placed and the fixing portion where the vertical frame material 93 is fixed with screws or the like can be protected. Furthermore, the gap between the vertical frame material 93 and the inner and outer shoji screens 2 is covered with (cover material) 933, and a hollow section is formed by the main vertical frame material 931 and the inner peripheral member (cover material) 933, making it difficult for flames to pass through in the event of a fire, protecting the fitting section 93a and improving fire resistance.

[0120] Furthermore, the inner periphery member 933 of this embodiment has end members 933B made of resin at its end. Therefore, even if the inner periphery member 933 expands due to heat during a fire at the inner periphery position of the main vertical frame member 931, the end members 933B melt and can absorb the expansion of the inner periphery member (cover member) 933, as shown in Figures 17 and 18. This prevents damage to fittings due to the expansion of the inner periphery member (cover member) 933 and prevents communication between the inside and outside of the room.

[0121] -Other embodiments- The upper and lower frame materials are not limited as long as they have fixing parts for fixing to the inner surface of the opening and guide parts for guiding the top and bottom of the shoji screen. Furthermore, the cross-sectional shape of the left and right vertical frame members is not limited as long as they form a visible wall portion (storage portion) that covers the edge of the shoji screen from inside and outside the room.

[0122] Furthermore, the materials for the upper frame material, lower frame material, and vertical frame material are not particularly limited, and may be metal materials such as stainless steel or aluminum, or other flame-retardant materials.

[0123] It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
