Fitting

Abstract

To provide a fitting capable of preventing a resin cover from falling off due to thermal deformation.SOLUTION: An upper frame 13 has a metal shaped material 80, an outer upper resin molded body 90B, a first metal member 210 attached to the metal shaped material 80, a second metal member 220 sandwiching the outer upper resin molded body 90B between the first metal member 210 and itself, and a fastener made of a metal material that penetrates the outer upper resin molded body 90B and joins the first metal member 210 and the second metal member 220. In this configuration, even when the outer upper resin molded body 90B is thermally deformed in a high-temperature environment, the outer upper resin molded body 90B is maintained in a state sandwiched between the first metal member 210 and the second metal member 220. Therefore, in a high-temperature environment, the outer upper resin molded body 90B can prevent the metal shaped material 80 from being directly exposed to heat and deforming, and ultimately can prevent the formation of flame penetration holes in the metal shaped material 80 in the indoor / outdoor directions due to the thermal deformation, thereby preventing the loss of fire resistance.SELECTED DRAWING: Figure 5

Description

[Technical field]

[0001] The present invention relates to fittings. [Background technology]

[0002] As a fitting in which a screen is slidably arranged relative to a frame, such as a sliding window, a fitting in which the frame has a metal shaped material and a resin cover is known (see, for example, Patent Document 1). In this fitting, the resin cover is engaged with the metal shaped material in a state where it covers the visible surface on the inner periphery side of the metal shaped material. The resin cover is intended to improve, for example, aesthetics, insulation, fire resistance, and moisture resistance. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-80550 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration of Patent Document 1, if the resin cover is thermally deformed in a high-temperature environment such as during a fire, the metal shape is released from its engagement and falls off, exposing the metal shape and making it susceptible to thermal deformation. If the metal shape is thermally deformed, a flame hole may be formed in the indoor / outdoor direction, compromising fire resistance.

[0005] In view of the above-mentioned circumstances, one of the objects of the present invention is to provide a fitting that can prevent a resin cover from falling off due to thermal deformation. [Means for solving the problem]

[0006] The building fixture of the present invention is a building fixture comprising a frame body consisting of left and right vertical frames, an upper frame, and a lower frame assembled all around, and a shoji screen arranged on the frame body in a state in which it slides in the extension direction of the lower frame, wherein the vertical frame or the upper frame comprises a metal shaped member having a visible surface on the inner circumference, a resin cover covering the visible surface, a first metal member attached to the metal shaped member, a second metal member located on the opposite side of the metal shaped member from the first metal member and sandwiching the resin cover between it and the first metal member, and a fastener made of a metal material that penetrates the resin cover and connects the first metal member and the second metal member. Effect of the Invention

[0007] According to the present invention, the first metal member, the second metal member, and the fastener are fixed to the metal profile and made of metal material, so that they do not deform or change position even in a high-temperature environment such as a fire. Therefore, even if the resin cover is deformed by heat in a high-temperature environment, the first metal member and the second metal member can maintain the state in which the resin cover is sandwiched between them and prevent the resin cover from falling. Therefore, in a high-temperature environment, the resin cover can prevent the metal profile from being directly exposed to heat and deforming, and thus can prevent the metal profile from being deformed by the thermal deformation in the indoor / outdoor directions, which would impair the fireproofing properties.

[0009] A preferred embodiment of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. For convenience, the terms "prospect direction" and "visible direction" may be used below. The "prospect direction" is the direction along the depth of the fittings, and may also be referred to as the indoor / outdoor direction. A surface along the prospective direction may be referred to as a "prospect surface." For members that extend along the horizontal direction, such as the upper and lower frames, the prospective direction is the direction along the top and bottom perpendicular to the prospective direction. For members that extend along the vertical direction, such as the vertical frame, the prospective direction is the direction along the horizontal perpendicular to the prospective direction. In addition, a surface along the prospective direction may be referred to as a "prospect surface."

The fitting shown here is called a sliding window, which comprises a frame 10, an outer screen 20A arranged on the outside of the frame 10, and an inner screen 20B arranged on the inside of the frame 10. The frame 10 is formed into a rectangular frame shape by assembling left and right vertical frames 11 and 12, an upper frame 13, and a lower frame 14 all around.

[0011] The outer screen 20A is configured with a rectangular double-glazed glass 21A and vertical frames 22A, upper frames 23A, lower frames 24A, and vertical frames 25A arranged around the double-glazed glass 21A. Similarly, the inner screen 20B is configured with a rectangular double-glazed glass 21B and vertical frames 22B, upper frames 23B, lower frames 24B, and vertical frames 25B arranged around the double-glazed glass 21B. In this embodiment, the outer screen 20A and the inner screen 20B are arranged to be movable along the longitudinal direction of the upper frame 13 and the lower frame 14 relative to the frame body 10, and when the outer screen 20A is arranged on the left side of the frame body 10 and the inner screen 20B is arranged on the right side when viewed from the inside of the room, the opening of the frame body 10 can be closed. When the opening of the frame body 10 is closed, the vertical frame 25A located on the right side of the outer screen 20A and the vertical frame 25B located on the left side of the inner screen 20B are aligned in the front direction when viewed from the inside of the room. On the other hand, when the opening of the frame body 10 is open, the outer screen 20A and the inner screen 20B are at least partially overlapping in the front direction. Hereinafter, the vertical frames 25A and 25B are referred to as the aligned frame portions 25A and 25B.

[0012] The vertical frames 22A, 22B, upper frames 23A, 23B, lower frames 24A, 24B, and joint frames 25A, 25B that make up the shoji screens 20A, 20B are all extruded shapes molded from resin, and are configured to have a cross-sectional shape that is almost uniform over the entire length along the longitudinal direction. In this embodiment, the vertical frames 22A, 22B, upper frames 23A, 23B, and lower frames 24A, 24B are particularly configured with the same cross-sectional shape to make up the shoji screens 20A, 20B. The joint frames 25A, 25B are configured with different cross-sectional shapes.

[0013] On the other hand, the vertical frames 11, 12, upper frame 13, and lower frame 14 that make up the frame 10 are composite types that are comprised of metal shapes made of extruded shapes formed from metal such as aluminum alloy, and resin shapes made of extruded shapes formed from resin. The metal shapes and resin shapes are also configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction.

[0014] As shown in Figures 2 and 3, each component constituting the vertical frames 11, 12, upper frame 13, and lower frame 14 is attached to the building frame or a frame fixed to the frame via mounting screws 400.

[0015] Below, we will explain the configuration of the vertical frames 11, 12, upper frame 13, and lower frame 14 that make up the frame and frame body 10 of the shoji screens 20A, 20B, as well as the characteristics of the present invention. For convenience, in the following, the vertical frame located on the left side as viewed from inside the room will be referred to as the left vertical frame 11, and the vertical frame located on the right side will be referred to as the right vertical frame 12.

[0016] (Stile 22A) As shown in FIG. 3, the vertical frame 22A is formed by integrally forming a frame base 31, a glass clamping piece 32, an inner rail guide 33, and an outer rail guide 34. The frame base 31 is hollow and has a substantially rectangular cross section. A ridge 35 is provided on the edge of the inner circumference of the frame base 31 that faces the outside of the room. The ridge 35 clamps the insulating glass 21A between the glass clamping piece 32 and the frame base 31. The glass clamping piece 32 protrudes from the edge of the inner circumference of the frame base 31 that faces the inside of the room to the inner side. The inner rail guide 33 protrudes from the edge of the outer circumference of the frame base 31 that faces the inside of the room to the outer side, and the outer rail guide 34 protrudes from the edge of the outer circumference of the frame base 31 that faces the outside of the room to the outer side. A gap is provided between the inner rail guide 33 and the outer rail guide 34, and a tension material 36 is provided at the portions facing each other.

[0017] (Stile 25A) The vertical frame 25A that constitutes the joining frame parts 25A, 25B is formed integrally with a frame base 31 and a glass clamping piece 32. The frame base 31 is hollow and has a roughly rectangular cross section. A press-in edge 35 is provided on the inner periphery of the frame base 31 at the edge facing the outside of the room. The press-in edge 35 clamps the insulating glass 21A between itself and the glass clamping piece 32. The glass clamping piece 32 protrudes inward from the inner periphery of the frame base 31 at the edge facing the inside of the room.

[0018] (Left vertical frame 11) As shown in FIG. 3, the left vertical frame 11 has a metal profile 40 and resin profiles 51 and 52. The resin profile 51 is engaged and integrated with the metal profile 40 via a plurality of claw structures. The resin profile 52 is engaged and integrated with the resin profile 51 via a plurality of claw structures. The metal profile 40 and the resin profiles 51 and 52 each have a cross-sectional shape having a plurality of plate portions extending in different directions, and extend in the up-down direction. The resin profiles 51 and 52 are provided so as to cover a portion of the visible surface on the inner periphery side of the metal profile 40.

[0019] (Right vertical frame 12) As shown in Fig. 3, the right vertical frame 12 has a metal profile 60 and a resin profile 70 that is engaged and integrated with the metal profile 60 via a plurality of claw structures. The metal profile 60 and the resin profile 70 each have a cross-sectional shape with a plurality of plate portions extending in different directions, and extend in the up-down direction. The resin profile 70 is provided so as to cover a portion of the visible surface on the inner periphery side of the metal profile 60.

[0020] (Bottom frame 14) As shown in FIG. 2, the metal profile 120 of the lower frame 14 is configured with an inner lower metal molding 120A on the indoor side and an outer lower metal molding 120B on the outdoor side. The inner lower metal molding 120A and the outer lower metal molding 120B are connected to each other by a bridge material (insulation material) 120C formed from an insulating material, and are thermally insulated without contacting each other. The outer lower metal molding 120B has a closed cross-sectional structure and houses a reinforcing member 150 therein. The reinforcing member 150 is provided with a thermal expansion member 303. The inner lower metal molding 120A, the outer lower metal molding 120B, and the bridge material 120C are provided with a thermal expansion member 304 on the inner periphery side. These thermal expansion members 303, 304 are heat-expanding materials such as graphite that foam and expand when heated.

[0021] (Top frame 13) As shown in Figures 2 and 4, the metal profile 80 of the upper frame 13 is configured with an inner upper metal molding 80A on the indoor side and an outer upper metal molding 80B on the outdoor side. These inner upper metal molding 80A and outer upper metal molding 80B are connected to each other by a bridge material 80C formed from a heat insulating material, and are thermally insulated without coming into contact with each other. The inner upper metal molding 80A is an example of a first molding material on the indoor side, and the outer upper metal molding 80B is an example of a second molding material on the outdoor side, and the bridge material 80C is made of a resin material such as urethane. The bridge material 80C is an example of a connecting member.

[0022] As shown in FIG. 4, the inner upper metal molding 80A is formed by integrally molding the upper inner projection plate portion 81, the upper inner sight plate portion 82, and the upper inner pocket portion 83. The upper inner projection plate portion 81 is a plate-like member extending along the projection direction. The upper inner sight plate portion 82 constitutes the metal rail portion of the inner upper horizontal rail 13B for guiding the inner screen 20B, and has a metal rail base plate portion 82a extending from the edge portion on the outside of the upper inner projection plate portion 81 toward the inner periphery, an inclined extension portion 82b, and a projection protrusion portion 82e. The extension length of the metal rail base plate portion 82a is set so that when the inner screen 20B is arranged on the frame body 10, it is located on the outer periphery side of the contact position of the tension material 36 provided on the upper frame 23B. The inclined extension 82b is inclined so as to gradually become more outside the room from the inner periphery side of the metal rail base plate 82a toward the inner periphery side. The projecting protrusion 82e extends in the projecting direction from the surface of the inclined extension 82b facing the room toward the inside of the room.

[0023] In this inner upper metal molding 80A, an engagement receiving portion 81a is provided on the upper inner projection plate portion 81. Also, an engagement receiving portion 82g is provided on the upper inner sight plate portion 82. These engagement receiving portions 81a, 82g are for maintaining a resin profile 90, described below, attached to the inner periphery of the upper inner projection plate portion 81. In the illustrated example, the engagement receiving portions 81a, 82g are provided on the edge portion located on the indoor side of the upper inner projection plate portion 81 and on the outer periphery of the metal rail base plate portion 82a in the upper inner sight plate portion 82, respectively.

[0024] The outer upper metal molding 80B is formed by integrally molding the upper outer projection plate portion 84, the upper outer sight plate portion 85, the upper outer pocket portion 86, the upper fixed sight plate portion 87, and the upper outer cover plate portion 88. The upper outer projection plate portion 84 is a plate-like member extending along the projection direction. The upper outer sight plate portion 85 constitutes the metal rail portion of the outer upper horizontal rail 13A for guiding the outer sash 20A, and extends from the edge portion of the upper outer projection plate portion 84 on the outside of the room toward the inner circumference side, and then extends toward the inside of the room. The upper outer sight plate portion 85 has an upper fitting portion 85a on the extended edge portion extending toward the inside of the room. The upper fitting portion 85a is intended to restrict the movement of the upper outer projection plate portion 84 in the projection direction away from each other by fitting into the upper fitting portion 97a of the resin profile 90 described later. In the illustrated example, the upper fitting portion 85a is formed by extending from the extended edge of the upper outer sight plate portion 85 toward the outer periphery, then bending toward the interior side of the room, and then bending further toward the inner periphery. The upper outer pocket portion 86 is a groove-shaped recess for accommodating the bridge material 80C, and is provided so as to open to the interior side at the edge portion that is the interior side of the upper outer sight plate portion 84. The upper fixing sight plate portion 87 is a flat plate extending from the upper outer pocket portion 86 toward the outer periphery. The upper outer cover plate portion 88 extends from the edge portion that is the exterior side of the room of the upper outer sight plate portion 84 toward the inner periphery.

[0025] This outer upper metal molding 80B has a plurality of upper engagement receiving portions 84a in the portion that is the inner periphery side of the upper outer projection plate portion 84, and a plurality of thick portions 84b between the upper engagement receiving portions 84a. The upper engagement receiving portions 84a are for maintaining the resin profile 90 described below attached to the inner periphery side of the upper outer projection plate portion 84. In the illustrated example, the upper engagement receiving portions 84a are provided in the portion of the upper outer pocket portion 86 facing the outside of the room and in the portion of the projection surface of the upper outer projection plate portion 84 that is closer to the room side than the upper outer sight plate portion 85. The thick portions 84b are formed by partially increasing the plate thickness of the upper outer projection plate portion 84, and are provided along the longitudinal direction of the upper frame 13.

[0026] 2, the resin profile 90 of the upper frame 13 is configured with an inner upper resin molding 90A on the indoor side and an outer upper resin molding 90B on the outdoor side. The inner upper resin molding 90A and the outer upper resin molding 90B each have a length covering the entire length of the portion of the upper frame 13 located between the left and right vertical frames 11, 12.

[0027] As shown in Fig. 4, the inner upper resin molding 90A is formed by integrally molding the upper inner cover base 91, the upper inner rail cover part 92, the upper sight cover part 93, the upper frame cover part 94, and the extension cover part 95. The upper inner cover base 91 is a flat plate that covers the upper inner projection plate part 81 of the inner upper metal molding 80A. The upper inner cover base 91 is detachably attached to the inner upper metal molding 80A by inserting the edge part on the outside of the room between the engagement receiving part 82g provided on the metal rail base plate part 82a and the upper inner projection plate part 81, and inserting the edge part on the inside of the room between the engagement receiving part 81a on the inside of the room and the upper inner projection plate part 81. On the other hand, the upper inner rail cover part 92, together with the upper inner rail outer cover part 98, the upper inner rail inner periphery cover part 99, and the upper inner rail inner cover part 100 of the outer upper resin molded body 90B, constitutes the resin rail part of the upper horizontal rail 13B corresponding to the inner sash 20B, and extends from the upper inner cover base part 91 toward the inner periphery. The inner periphery edge of the upper inner rail cover part 92 is configured to extend approximately in contact with the indoor side of the metal rail base plate part 82a of the upper inner sight plate part 82 when the upper inner cover base part 91 is abutted against the upper inner sight plate part 81, so as to cover the indoor side. The outer periphery side of the upper inner rail cover part 92 is provided with an engagement protrusion 92a for engaging with the engagement receiving part 82g. The upper sight cover part 93 extends from the indoor side edge of the upper inner cover base part 91 toward the inner periphery. An engaging protrusion 93a for engaging with the engaging receiving portion 81a is provided on the outer peripheral portion of the upper sight cover portion 93. The upper frame cover portion 94 extends in the projection direction from the edge portion on the inner peripheral side of the upper sight cover portion 93 toward the inside of the room. The extended cover portion 95 extends from the edge portion on the outer peripheral side of the upper frame cover portion 94 toward the inner peripheral side. The extended edge portion of the extended cover portion 95 extends to a position that is more inward than the edge portion on the inner peripheral side of the upper inner rail cover portion 92.

[0028] The outer upper resin molded body 90B is formed by integrally molding the upper outer cover base 96, the inner cover part 97 for the upper outer rail, the outer cover part 98 for the upper inner rail, the inner periphery cover part 99 for the upper inner rail, and the inner cover part 100 for the upper inner rail. The outer upper resin molded body 90B covers a part of the inner peripheral side of the projection surface 84c of the upper outer projection plate part 84. The upper outer cover base 96 is a flat plate that covers a part of the upper outer projection plate part 84 of the outer upper resin molded body 90B. The upper outer cover base 96 extends in the indoor / outdoor direction at a position away from the projection surface 84c and approximately along the projection surface 84c. The upper outer rail inner cover part 97 is for forming the resin rail part of the upper horizontal rail 13A corresponding to the outer sash 20A, and extends from the edge part located on the outside of the room of the upper outer cover base 96 toward the inner peripheral side, that is, away from the projection surface 84c. An upper fitting portion 97a is provided on the edge of the inner circumference of the upper outer rail inner cover portion 97. The upper fitting portion 97a extends from the extended edge of the upper outer rail inner cover portion 97 toward the outside of the room, and then bends toward the outer circumference. The upper outer rail inner cover portion 97 is in a state of covering the sighting surface of the upper outer sighting plate portion 85 facing the room, while securing a space between the upper outer sighting plate portion 85 and the upper outer sighting plate portion 85, by fitting the upper fitting portion 97a into the upper fitting portion 85a of the upper outer sighting plate portion 85. The upper inner rail outer cover portion 98, the upper inner rail inner circumference cover portion 99, and the upper inner rail inner cover portion 100, together with the upper inner rail cover portion 92 of the inner upper resin molded body 90A, are for forming the resin rail portion of the upper horizontal rail 13B corresponding to the inner sash 20B. The upper inner rail outer cover part 98 extends from the edge part located on the indoor side of the upper outer cover base part 96 toward the inner circumference, i.e., away from the visible surface 84c, thereby covering the outdoor side of the upper inner sight plate part 82. The upper inner rail inner circumference cover part 99 is provided and extends from the extending edge part of the upper inner rail outer circumference cover part 98 into the room, thereby covering the inner circumference side of the upper inner sight plate part 82. The upper inner rail inner cover part 100 extends from the extending edge part of the upper inner rail inner circumference cover part 99 toward the outer circumference side, thereby covering the sight surface of the part of the upper inner sight plate part 82 located more inward than the metal rail base plate part 82a.The extension length of the inner cover part 100 for the upper inner rail is set so that when the inner screen 20B is arranged on the frame body 10, the tension material 36 provided on the upper frame 23B will not abut against the cover part 92 for the upper inner rail or the joint 101 with the cover part 92 for the upper inner rail. The upper outer cover base 96, the outer cover part 98 for the upper inner rail, and the inner cover part 97 for the upper outer rail all extend in an extension direction E (see Figures 1, 3, etc.). The extension direction E is perpendicular to the paper surface in Figures 2 and 4. The upper outer cover base 96, the outer cover part 98 for the upper inner rail, and the inner cover part 97 for the upper outer rail have a generally U-shaped groove shape that is open on the inner periphery side. The upper outer cover base 96 is an example of a bottom wall, the upper inner rail outer cover part 98 is an example of a first side wall, and the upper outer rail inner cover part 97 is an example of a second side wall. The upper inner rail outer cover part 98, the upper inner rail inner periphery cover part 99, and the upper inner rail inner cover part 100 form a recess that opens to the outer periphery, and the upper inner spotting plate part 82 is partially housed inside the recess. The upper inner rail inner cover part 100 is provided with an intermediate engagement part 100a. The intermediate engagement part 100a engages with the outer periphery side of the projection part 82e, thereby restricting the movement of the upper inner rail inner periphery cover part 99 toward the inner periphery side relative to the upper inner spotting plate part 82. The outer upper resin molded body 90B is an example of a resin cover.

[0029] This outer upper resin molding 90B has a plurality of engaging protrusions 96a and supporting protrusions 96b on the outer peripheral side of the upper outer cover base 96, and mounting protrusions 97b, 98a are provided on the upper outer rail inner cover part 97 and the upper inner rail outer cover part 98, respectively. The engaging protrusions 96a extend from the upper outer cover base 96 toward the outer peripheral side and have an engaging claw part 96c on the extended edge. The engaging claw part 96c engages with the upper engaging receiving part 84a provided on the outer upper metal molding 80B to secure a space between the upper outer cover base 96 and the upper outer projection plate part 84, and maintains the upper outer cover base 96 in a state in which it covers a part of the projection surface that is the inner peripheral side of the upper outer projection plate part 84. The supporting protrusions 96b extend from the upper outer cover base 96 toward the outer peripheral side between the engaging protrusions 96a. The support projection 96b is sized so that when the engagement claw portion 96c of the engagement projection 96a is engaged with the upper engagement receiving portion 84a, the extended edge portion is disposed in a position close to the upper outer projection plate portion 84 between the thick portions 84b provided on the upper outer projection plate portion 84. The mounting projections 97b, 98a respectively protrude in a direction close to each other from the portion of the upper outer rail inner cover portion 97 that is the room inside and the portion of the upper inner rail outer cover portion 98 that is the room outside. These mounting projections 97b, 98a engage with each other when the upper outer rail inner cover portion 97 and the upper inner rail outer cover portion 98 are fitted with the upper wind stopper member 110A (see Figs. 2 and 11) to prevent the upper wind stopper member 110A from falling off. The upper wind-stop member 110A is molded from an elastic resin material and, as shown in Figure 11, is disposed on the projected inner periphery surface of the upper frame 13 at the portion corresponding to the joining frame portions 25A, 25B in order to restrict the flow of air between the inside and outside of the room.

[0030] (Support structure of outer upper resin molded body 90B) In the frame 10 having the above-mentioned configuration, in a high-temperature environment such as during a fire, the outer upper resin molding 90B made of resin may be deformed by heat, and may become disengaged from the metal profile 80 and fall off. In this case, there is a risk that the fire resistance of the frame 10 may be reduced.

[0031] Therefore, in this embodiment, the frame 10 has a support structure for the outer upper resin molding 90B as shown in FIG. 5. The support structure is fixed to the metal material 80. The support structure also has a first metal member 210, a second metal member 220, and fasteners 230, 240, all of which are made of metal materials. Therefore, the support structure does not deform or change position even in a high-temperature environment where the resin material deforms. Therefore, by supporting the outer upper resin molding 90B via the support structure, it is possible to prevent the outer upper resin molding 90B from falling off. The first metal member 210, the second metal member 220, and the fasteners 230, 240 are made of metal materials such as iron-based materials and aluminum-based materials.

[0032] Specific examples of the first metal member 210, the second metal member 220, and the fasteners 230, 240 will be described in detail below with reference to Figures 5 to 11. Note that Figures 6 to 8 show the orientation of the first metal member 210 in a state where it is incorporated into the frame 10.

[0033] As shown in Fig. 5, the first metal member 210 is attached to the upper inner sight plate 82, which is a part of the inner upper metal molding 80A, by a fastener 230. The first metal member 210 is located between the metal shaped material 80 and the bridge material 80C, and the outer upper resin molding 90B. The second metal member 220 is located on the opposite side of the first metal member 210 to the metal shaped material 80, and sandwiches the upper outer cover base 96, which is a part of the outer upper resin molding 90B, between the first metal member 210 and the second metal member 220. The fastener 240 penetrates the upper outer cover base 96 and fastens the first metal member 210 and the second metal member 220.

[0034] The first metal member 210 has an extension portion 211 , a first fixing portion 212 , a second fixing portion 213 , and a hook portion 214 .

[0035] The extension portion 211 extends generally along the indoor / outdoor direction as shown in Figures 5 and 6, and also extends generally along the extension direction E of the upper frame 13 as shown in Figure 8, and has a generally rectangular and plate-like shape. Note that, as shown in Figures 5 and 6, in this example, the outdoor side end of the extension portion 211 is positioned slightly upwardly shifted relative to the indoor side end, and therefore the extension portion 211 has a bent shape.

[0036] As shown in Figures 5 and 6, the first fixing portion 212 protrudes from the indoor end of the extension portion 211 toward the inner periphery while contacting the outdoor side of the metal rail base plate portion 82a. Also, as shown in Figure 7, the first fixing portion 212 extends approximately along the extension direction E of the upper frame 13, and has a substantially rectangular and plate-like shape. The first fixing portion 212 is provided with coupling holes 212a penetrating in its thickness direction, i.e., in the indoor-outdoor direction, at multiple locations (two locations in this example) spaced apart in the extension direction E.

[0037] 5 and 6, the fastener 230 penetrates the metal rail base plate portion 82a in the indoor / outdoor direction and is coupled to the coupling hole 212a to integrate the first fixing portion 212 and the metal rail base plate portion 82a. This attaches the first metal member 210 to the inner upper metal molding body 80A. The fastener 230 is, for example, a screw having a head on the indoor side, and the coupling hole 212a is, for example, a female threaded hole. In this case, the fastener 230 is screwed from the indoor side using a tool such as a screwdriver.

[0038] The coupling hole 212a is provided in the upper inner sight plate portion 82, which is a portion not exposed to the outdoors (outdoors) of the inner upper metal formed body 80A constituting the metal shaped material 80. That is, the first metal member 210 is attached to the portion of the metal shaped material 80 that is not exposed to the outdoors.

[0039] As shown in FIG. 8, the hook portion 214 is provided at the outdoor end of two regions of the extension portion 211 that are both ends in the extension direction E, and as shown in FIGS. 5 and 6, the hook portion 214 protrudes from the extension portion 211 toward the outer periphery (upward). As shown in FIG. 5, the hook portion 214 faces the outdoor side of the upper outer pocket portion 86 and the upper engagement receiving portion 84a, which are part of the outer upper metal molding body 80B. The action and effect of the hook portion 214 will be described later. The hook portion 214 is aligned with the indoor side engagement protrusion 96a (see FIG. 4) in the extension direction E. This configuration is realized by partially cutting out the engagement protrusion 96a at the location where the first metal member 210 is provided.

[0040] As shown in Fig. 8, the second fixing portion 213 is provided at the outdoor end of a region that is approximately the center of the extension portion 211 in the extension direction E, and protrudes toward the outdoor side compared to other portions of the extension portion 211. As shown in Fig. 6, the second fixing portion 213 is provided with a coupling hole 213a that penetrates in the thickness direction, i.e., in the vertical direction.

[0041] 5, the thermal expansion member 302 is provided between the first metal member 210 and the metal shaped member 80 or the bridge member 80C. The thermal expansion member 302 may be attached to the first metal member 210, or to the metal shaped member 80 or the bridge member 80C, via an adhesive or double-sided tape. The thermal expansion member 302 is an example of a second thermal expansion member. The thermal expansion member 302 is similar to the thermal expansion members 303 and 304, and is a heat-expanding material, such as graphite, that foams and expands when heated.

[0042] The second metal member 220 extends generally along the indoor-outdoor direction as shown in FIG. 5, and also extends generally along the extension direction E of the upper frame 13 as shown in FIG. 9, and has a generally rectangular, plate-like shape.

[0043] As shown in FIG. 5, the fastener 240 penetrates the thermal expansion member 301, the second metal member 220, and the upper outer cover base 96 in the finder direction (vertical direction) and is fastened to the fastening hole 213a, thereby integrating the second metal member 220 and the second fixing portion 213. In other words, the fastener 240 integrates the first metal member 210 and the second metal member 220 with the outer upper resin molded body 90B sandwiched therebetween. The fastener 240 is, for example, a screw having a head 240a on the lower side, and the fastening hole 213a is, for example, a female screw hole. In this case, the fastener 240 is screwed from the lower side using a tool such as a screwdriver, and the thermal expansion member 301 is sandwiched between the head 240a and the second metal member 220.

[0044] The thermal expansion member 301 is attached to the inner visible surface of the second metal member 220 via an adhesive, double-sided tape, or the like. The thermal expansion member 301 is similar to the thermal expansion members 303 and 304, and is a heat-expanding material, such as graphite, that foams and expands when heated. The thermal expansion member 301 is an example of a first thermal expansion member.

[0045] As shown in FIG. 5, the second metal member 220 is in contact with the upper outer cover base 96. As shown in FIGS. 5 and 9, the second metal member 220 is connected to the first metal member 210 by a fastener 240, for example, a screw. The second metal member 220 has a plate-shaped portion 221, a protrusion 222, and a protrusion 223. The plate-shaped portion 221 extends substantially along the upper outer cover base 96 and is formed in a rectangular shape. The protrusion 222 protrudes from an end 221a on the indoor side of the plate-shaped portion 221 toward the indoor side. The protrusion 223 protrudes from an end 221b on the outdoor side of the plate-shaped portion 221 toward the outdoor side. In the attached state of the second metal member 220, as shown in FIG. 9, the protrusion 222 contacts or bites into the upper inner rail outer cover portion 98, and the protrusion 223 contacts or bites into the upper outer rail inner cover portion 97. As a result, the second metal member 220 is in a state of being tensioned between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97. In other words, the protrusions 222 and 223 are tensioned between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97 on opposite sides of the fastener 240. The protrusion 222 is an example of a first protrusion, and the protrusion 223 is an example of a second protrusion.

[0046] In the mounting state shown in FIG. 9, the end 221a on the indoor side of the plate-shaped portion 221 extends approximately along the extension direction E and faces the upper inner rail outer cover part 98, which also extends approximately along the extension direction E, with a gap therebetween. The end 221b of the plate-shaped portion 221 extends approximately along the extension direction E and faces the upper outer rail inner cover part 97, which also extends approximately along the extension direction E, with a gap therebetween. As a result, in the mounting state, the plate-shaped portion 221 extends in the indoor / outdoor direction between a position close to the upper inner rail outer cover part 98 and a position close to the upper outer rail inner cover part 97. The thermal expansion member 301 is provided on the surface of the plate-shaped portion 221 opposite the upper outer cover base part 96, i.e., in the portion facing the shoji screens 20A and 20B.

[0047] 9 and 10, in the pre-installation state shown in FIG. 10, the second metal member 220 is disposed at a position (posture) rotated a predetermined angle in the counterclockwise direction at the rotation center of the fastener 240 from the position in the installation state shown in FIG. 9. Here, the counterclockwise direction is the opposite direction to the screw-turning direction of the fastener 240. The second metal member 220 is configured so that it can be accommodated between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97 in that position (posture). In this configuration, the fastener 240 as a screw is rotated clockwise from the pre-installation state shown in FIG. 10 using a screwdriver or the like. As a result, the second metal member 220 rotates clockwise by the predetermined angle due to friction between the head 240a of the fastener 240 and the second metal member 220, the fastener 240 is screwed, and the installation state shown in FIG. 9 is obtained. In addition, the protrusions 222, 223 are provided at positions in contact with a diagonal line DL of the plate-shaped part 221 displaced in the counterclockwise direction with respect to a virtual line M that passes through the rotation center of the fastener 240 and extends in the indoor / outdoor direction in the attached state. In this case, the radius (moment arm) of the protrusions 222, 223 with respect to the rotation center of the fastener 240 can be set larger. Therefore, the rotation stop torque of the second metal member 220 around the rotation center of the fastener 240 due to friction (engagement) with the upper inner rail outer cover part 98 or the upper outer rail inner cover part 97 can be set larger. In addition, the amount of bite of the protrusions 222, 223 into the upper inner rail outer cover part 98 or the upper outer rail inner cover part 97 to obtain the rotation stop torque can be made smaller. The above-mentioned predetermined angle, i.e., the rotation angle of the second metal member 220, is set to, for example, an acute angle equal to or smaller than a right angle.

[0048] As shown in Fig. 11, the first metal member 210, the second metal member 220, and the thermal expansion member 301 are arranged so as to overlap the upper part of the joining frame parts 25A and 25B. The upper wind stopper member 110A is arranged so as to be adjacent to the first metal member 210, the second metal member 220, and the thermal expansion member 301 in the extension direction E and to overlap the upper part of the joining frame parts 25A and 25B. The upper wind stopper member 110A, the first metal member 210, the second metal member 220, and the thermal expansion member 301 may be arranged in the opposite order to that in Fig. 11 in the extension direction E.

[0049] As described above, in this embodiment, the upper frame 13 has the metal shaped material 80 and the outer upper resin molded body 90B that covers the inner peripheral side of the metal shaped material 80. The upper frame 13 also has the first metal member 210, the second metal member 220, and the fastener 240. The first metal member 210 is attached to the metal shaped material 80. The second metal member 220 is located on the opposite side of the first metal member 210 to the metal shaped material, and sandwiches the outer upper resin molded body 90B between the first metal member 210 and the fastener 240. The fastener 240 is made of a metal material, penetrates the second metal member 220 and the outer upper resin molded body 90B, and is also made of a metal material. According to this configuration, the first metal member 210 and the second metal member 220 do not deform or change position even in a high temperature environment. Therefore, even if the outer upper resin molding 90B is thermally deformed in a high-temperature environment, the outer upper resin molding 90B remains sandwiched between the first metal member 210 and the second metal member 220. Therefore, in a high-temperature environment, the outer upper resin molding 90B can prevent the metal shaped material 80 from being directly exposed to heat and deforming, and furthermore, can prevent the formation of a flame penetration hole in the metal shaped material 80 in the indoor / outdoor direction due to the thermal deformation, thereby preventing the fireproofing from being impaired.

[0050] In addition, in this embodiment, the upper frame 13 has a bridge material 80C. The bridge material 80C is located between the inner upper metal forming body 80A and the outer upper metal forming body 80B, is made of a resin material, and connects the inner upper metal forming body 80A and the outer upper metal forming body 80B. The first metal member 210 is attached to the outer upper metal forming body 80B, which is one of the inner upper metal forming body 80A and the outer upper metal forming body 80B. In this configuration, the first metal member 210 is attached to the inner upper metal forming body 80A, which is one of the metal shapes 80. Therefore, even if the bridge material 80C is burned, the first metal member 210, the second metal member 220, and the fastener 240 will not deform and will not change position. Therefore, even in a configuration in which the bridge material 80C is provided, the outer upper resin molding 90B remains sandwiched between the first metal member 210 and the second metal member 220, and thus the loss of fire resistance can be suppressed.

[0051] Moreover, in this embodiment, the thermal expansion member 301 is attached to the second metal member 220 at a position facing the outer screen 20A and the inner screen 20B. In this configuration, the thermal expansion member 301 is attached to the second metal member 220, whose position does not change even in a high-temperature environment. With this configuration, in a high-temperature environment, the thermal expansion member 301 can be expanded more reliably in the gaps between the upper frame 13 and the outer screen 20A and the inner screen 20B, thereby sealing the gaps. Therefore, the thermal expansion member 301 can prevent the propagation of flames through the gaps.

[0052] In this embodiment, the second metal member 220 has a plate-shaped portion 221 extending substantially along the upper outer cover base 96. The end 221a on the indoor side of the plate-shaped portion 221 extends substantially along the upper inner rail outer cover portion 98 with a gap therebetween. The end 221b on the outdoor side of the plate-shaped portion 221 extends substantially along the upper outer rail inner cover portion 97 with a gap therebetween. With this configuration, the plate-shaped portion 221 can be configured wider between the upper inner rail outer cover portion 98 and the upper outer rail inner cover portion 97. Therefore, a larger thermal expansion member 301 can be attached to the plate-shaped portion 221, and thus the fire resistance of the thermal expansion member 301 can be further improved.

[0053] In this embodiment, the first metal member 210, the second metal member 220, and the thermally expandable member 301 are located at least above the joining frame parts 25A, 25B where the indoor side screen 20B and the outdoor side screen 20A overlap in the indoor / outdoor direction when the frame body 10 is in the closed state. With this configuration, in a high-temperature environment, the gap between the joining frame parts 25A, 25B and the upper frame 13 can be blocked by the expanded thermally expandable member 301. Therefore, the thermally expandable member 301 can prevent the propagation of flames through the gap.

[0054] Moreover, in this embodiment, the upper frame 13 includes a thermally expandable member 302 provided between the first metal member 210 and the metal shaped member 80 or the bridge member 80C. With this configuration, even if the bridge member 80C is burned, the thermally expandable member 302 can be expanded in the gap between the first metal member 210 and the metal shaped member 80 to close the gap. Therefore, the thermally expandable member 301 can prevent the propagation of flames through the gap.

[0055] In this embodiment, the first metal member 210 is attached to the outer upper metal forming body 80B, which is one of the inner upper metal forming body 80A and the outer upper metal forming body 80B. The first metal member 210 has a hook portion 214. The hook portion 214 hooks the inner upper metal forming body 80A so as to prevent the inner upper metal forming body 80A and the outer upper metal forming body 80B from moving apart in the indoor / outdoor direction. With this configuration, even if the bridge material 80C is burned, the hook portion 214 can prevent the inner upper metal forming body 80A and the outer upper metal forming body 80B from moving apart.

[0056] In this embodiment, the second metal member 220 is joined to the first metal member 210 by one fastener 240 in a state in which it is stretched between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97. This configuration allows the second metal member 220 to be fixed in a position in which it is stretched between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97. Therefore, with a relatively simple configuration, it is possible to suppress variation in the mounting position of the second metal member 220. Furthermore, in the case where a thermally expandable member 301 is attached to the second metal member 220, it is possible to suppress variation in the thermal expansion state (position) of the thermally expandable member 301.

[0057] In this embodiment, the second metal member 220 has a protrusion 222 protruding from the plate-shaped portion 221 toward the upper inner rail outer cover part 98, and a protrusion 223 protruding from the plate-shaped portion 221 toward the upper outer rail inner cover part 97. The protrusion 222 and the protrusion 223 are on opposite sides of the fastener 240 and brace between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97. With this configuration, a structure in which the second metal member 220 braces between the upper inner rail outer cover part 98 and the upper outer rail inner cover part 97 can be realized with a relatively simple configuration.

[0058] Moreover, in this embodiment, the first metal member 210 is attached to a portion of the metal profile 80 that is not exposed to the outdoors. According to this configuration, water leakage from the portion of the metal profile 80 where the first metal member 210 is attached can be suppressed.

[0059] In the above embodiment, a sliding window in which both the outer and inner shoji 20A and 20B slide relative to the frame 10 is exemplified, but it is also possible to configure it as a single sliding window in which only one of the shoji slides. In addition, the shoji 20A and 20B are exemplified as having frames 22A, 22B, 23A, 23B, 24A, 24B, 25A, and 25B molded from resin. However, the shoji is not limited to this configuration, and may have a frame molded from a metal such as an aluminum alloy on the outside of the room and a resin on the inside of the room. In addition, the metal shaped member 80 of the upper frame 13 is exemplified as having an inner upper metal molded body 80A and an outer upper metal molded body 80B connected by a bridge member 80C. In addition, the metal shaped member 120 of the lower frame 14 is exemplified as having an inner lower metal molded body 120A and an outer lower metal molded body 120B connected by a bridge member 120C. However, the metal profile is not limited to this configuration, and may not have a bridge material, and the indoor side portion and the outdoor side portion may be integrally formed.

[0060] In the above-described embodiment, the support structure for the outer upper resin molded body 90B (resin cover) made of the first metal member 210, the second metal member 220, and the fasteners 230, 240 is applied to the upper frame 13. However, this is not limited thereto, and the support structure for the resin cover can also be applied to the left vertical frame 11 and the right vertical frame 12. The support structure for the resin cover may be provided locally at only one location in the upper frame 13, the left vertical frame 11, or the right vertical frame 12, or may be provided at multiple locations spaced apart from each other in the extension direction of the frames. The support structure for the resin cover may be a structure that extends along each frame over substantially the entire length of each frame.

[0061] In the above embodiment, the first metal member 210 is attached to the inner upper metal molding body 80A (the first shaped member on the indoor side), but this is not limited thereto, and the first metal member may be attached to the second shaped member on the outdoor side. In this case, the second shaped member on the outdoor side may have a hook portion that prevents the first shaped member on the indoor side from moving away to the indoor side. In addition, the first metal member 210 is attached to the upper inner sight plate portion 82 of the inner upper metal molding body 80A, but this is not limited thereto, and the first metal member may be attached to another position of the first shaped member and the second shaped member that is not exposed to the outdoors.

[0062] In the above-described embodiment, the indoor end 221a and the outdoor end 221b of the plate-shaped portion 221 of the second metal member 220 face the upper inner rail outer cover portion 98 (first side wall) or the upper outer rail inner cover portion 97 (second side wall) with a gap therebetween. However, this is not limited to this, and the indoor and outdoor ends may contact the first side wall or the second side wall. Also, the protrusion 222 (first protrusion) and the protrusion 223 (second protrusion) may not contact the diagonal line DL of the plate-shaped portion 221.

[0063] In the above-described embodiment, only one thermally expandable member 302 (second thermally expandable member) is provided so as to face the inner upper metal molding 80A (first shaped member), the outer upper metal molding 80B (second shaped member), and the bridge member 80C (connecting member). However, this is not limited to this, and the second thermally expandable member may be provided in a plurality of parts, or may be provided so as to face at least one of the first shaped member, the second shaped member, and the connecting member. The second thermally expandable member can be installed in various positions. Furthermore, the second thermally expandable member may be attached to the first metal member, or to the metal shaped member or the connecting member.

[0064] In the building fixture of the present invention, the metal profile has a first profile on the inside of the room and a second profile on the outside of the room, the vertical frame or the upper frame is located between the first profile and the second profile and has a connecting member made of a resin material that connects the first profile and the second profile, and the first metal member is attached to one of the first profile and the second profile. According to the present invention, the first metal member is attached to the metal extrusion. Therefore, even if the connecting member is burned in a high-temperature environment, the first metal member, the second metal member, and the fastener are not deformed and do not change position. Therefore, even if the frame body has the connecting member, the first extrusion and the second extrusion maintain the state in which the resin cover is sandwiched in a high-temperature environment, preventing the resin cover from falling off and thus preventing the fire resistance from being impaired.

[0065] The fixture includes a first thermally expandable member attached to a portion of the second metal member facing the shoji screen. According to the present invention, the first thermal expansion member is attached to the second metal member, which does not deform or change position even in a high-temperature environment. Therefore, in a high-temperature environment, the first thermal expansion member can be expanded more reliably in the gap between the frame and the screen to close the gap. Therefore, the first thermal expansion member can prevent the propagation of flames through the gap.

[0066] In the above-mentioned building fixture, the resin cover has a bottom wall extending along the inner circumferential surface of the metal profile and extending in the extension direction of the metal profile, a first side wall protruding inward from the bottom wall and extending in the extension direction of the metal profile, and a second side wall protruding inward from the bottom wall on the outdoor side of the first side wall and extending in the extension direction of the metal profile, and the second metal member has a plate-shaped portion extending along the bottom wall, with the indoor side end of the plate-shaped portion extending along the first side wall with a gap or in contact with the first side wall, and the outdoor side end of the plate-shaped portion extending along the second side wall with a gap or in contact with the second side wall. According to the present invention, the plate-shaped portion between the first side wall and the second side wall can be made wider, and thus a larger first thermally expandable member can be attached to the plate-shaped portion, thereby further improving the fire resistance of the first thermally expandable member.

[0067] In the above-mentioned fixture, the shoji screen has an indoor shoji screen and an outdoor shoji screen that overlap each other when the frame is open, the first metal member is attached to the metal profile that constitutes the upper frame, and the first metal member, the second metal member and the first thermally expandable member are positioned at least above the joining frame portion where the indoor shoji screen and the outdoor shoji screen overlap in the indoor-outdoor direction when the frame is closed. According to the present invention, in a high-temperature environment, the gap between the joint frame portion and the frame body can be blocked by the expanded first thermally expandable member. Therefore, the first thermally expandable member can prevent the propagation of flames through the gap.

[0068] The fixture includes a second thermally expandable member provided between the first metal member and the metal profile or the connecting member. According to the present invention, even if the connecting member is burned down, the second thermally expandable member can expand in the gap between the first metal member and the metal profile to close the gap, thereby preventing the propagation of flames through the gap.

[0069] In the building fixture, the first metal member has a hook portion that hooks the other of the first and second profiles so as to prevent the first and second profiles from moving away from each other in the indoor / outdoor direction. According to the present invention, even if the connecting member is burned down due to a fire, the hook portion can prevent the first and second extrusions from separating from each other.

[0070] In the building fixture, the resin cover has a bottom wall extending along the inner circumferential surface of the metal profile and extending in the extension direction of the metal profile, a first side wall protruding inward from the bottom wall and extending in the extension direction of the metal profile, and a second side wall protruding inward from the bottom wall on the outside of the first side wall and extending in the extension direction of the metal profile, and the second metal member is joined to the first metal member by one of the fasteners in a state of being braced between the first side wall and the second side wall. According to the present invention, since the second metal member can be fixed in a braced position between the first side wall and the second side wall, the variation in the mounting position of the second metal member can be suppressed with a relatively simple configuration. Furthermore, when the first thermally expandable member is attached to the second metal member, the variation in the thermal expansion state (position) of the first thermally expandable member, and therefore the variation in fire resistance, can be suppressed.

[0071] In the above-mentioned building fixture, the second metal member has a plate-shaped portion extending along the bottom wall, a first protrusion protruding from the plate-shaped portion toward the first side wall, and a second protrusion protruding from the plate-shaped portion toward the second side wall, the first protrusion and the second protrusion being braced between the first side wall and the second side wall on opposite sides of the fastener. According to the present invention, a structure in which the second metal member braces between the first side wall and the second side wall can be realized with a relatively simple configuration.

[0072] In the above-mentioned building fixture, the first metal member is attached to a portion of the metal profile that is not exposed to the outdoors. According to the present invention, water leakage can be suppressed at the portion of the metal profile where the first metal member is attached. [Explanation of symbols]
