Mode for Carrying Out the Invention

[0009] [First Embodiment] Hereinafter, the first embodiment of the present disclosure will be described in detail with reference to the drawings. In this specification, the "viewing direction" indicates the surface direction of the furniture housed in the opening formed in the building, and the "prospective direction" indicates the thickness direction and the indoor / outdoor direction of the above furniture. In the drawings of this specification, the outdoor side in the prospective direction of the furniture is designated as X1, and the indoor side in the prospective direction of the furniture is designated as X2. Also, the lateral direction in the viewing direction of the furniture is defined as the left-right direction.

[0010] As shown in FIG. 1, the furniture 1 of the present embodiment is provided in an opening 10 formed in a building body 100 such as a wooden house, a condominium, or other buildings such as a building. As shown in FIGS. 1 and 2, the furniture 1 includes an outdoor structure 11 on the X1 side of the opening 10. In FIG. 1, the screen door 6 is omitted.

[0011] The outdoor structure 11 is a deck installed outdoors or on a veranda of a building, but is not limited thereto. Any structure may be used as long as it is provided on the X1 side (outdoor side) of the lower frame 22 of the furniture 1 described later and is continuously arranged toward the X2 side (indoor side). For example, a drainage grating provided between the furniture 1 and the veranda may be used. The outdoor structure 11 is arranged so as to be accessible from the indoor side through the opening 10 where the furniture 1 is provided.

[0012] Note that the shape and configuration of the outdoor structure 11 are not limited, and can be appropriately changed according to the design, such as a configuration combining a plurality of floorboards. As shown in FIG. 2, the outdoor structure 11 has a walkable floor surface 111 and an end surface 112 on the fitting 1 side. In the drawings of this specification, the structure of support members and the like that support the outdoor structure 11 shall be omitted.

[0013] As shown in FIGS. 2 and 5, the fitting 1 is a sliding sweep-out window and is fixed to the inner frame 12 of the building body 100 and the indoor floor surface F1. The inner frame 12 is a three-sided frame and has an upper frame 121 and a pair of vertical frames 122, 122. The inner frame 12 is arranged to extend along the opening edge of the opening 10 toward the X2 side.

[0014] The fitting 1 includes a frame body 2, a shoji 50, a screen door 6, and an airtight material 7. The frame body 2 is formed by a substantially rectangular frame assembly of an upper frame 21, a lower frame 22, and vertical frames 23, 24 arranged in the left-right direction. The frame body 2 is constituted by, for example, a profile obtained by extrusion molding a metal such as aluminum, but is not limited thereto. The shoji 50 and the screen door 6 constitute the door body of the present disclosure. The door body is provided so as to be slidable within the frame body 2. In the present disclosure, the door body is a general term including shoji and screen doors, and also includes storm doors and the like.

[0015] As shown in FIG. 3, the upper frame 21 is a so-called double-groove type upper frame that does not have a rail that hangs down for sliding the shoji. The upper frame 21 is divided into two in the prospect direction into an outdoor side frame portion 211 and an indoor side frame portion 212, and the space between the outdoor side frame portion 211 and the indoor side frame portion 212 is integrally connected by a resin bridge material 25. By the resin bridge material 25, heat transfer in the prospect direction in the upper frame 21 can be blocked. With this configuration, the heat insulation property of the upper frame 21 can be improved. The upper frame 21 has a resin upper frame 213 provided on the inner peripheral surface on the X2 side.

[0016] The exterior frame portion 211 includes a rail guide wall 211a, an exterior facing wall 211b, an interior facing wall 211c, and a fitting groove 211d that connects the exterior facing wall 211b and the interior facing wall 211c and opens downward. The upper frame 61 for the screen door 6, which will be described later, is slidably mounted on the rail guide wall 211a. The screen door 6 is positioned on the X1 side of the exterior facing wall 211b. The exterior facing wall 211b and the interior facing wall 211c form an exterior groove portion 21a that opens downward. An airtight material 7 is fitted into the fitting groove 211d and extends toward the sash 50 side. The airtight material 7 will be described in detail later. The interior facing wall 211c is provided with a sealing material 13 that abuts against the outer sash 4 that constitutes the sash 50, which will be described later.

[0017] The resin upper frame 213 is a resin member with a roughly concave cross-section that opens downwards, and is provided on the X2 side of the interior facing wall 211c and on the inner circumferential surface of the upper frame 21. The resin upper frame 213 forms an interior groove 21b that opens downwards on its upper surface. The upper part of the outer sash 4 is housed in the exterior groove 21a, and the upper part of the interior sash 3, which will be described later, is housed in the interior groove 21b.

[0018] The resin upper frame 213 has an upper surface portion 213a, a fitting groove 213b formed on the inner circumference side of the upper surface portion 213a, and an angle portion 213c with a substantially L-shaped cross-section that is positioned on the X2 side. The angle portion 213c has a plurality of hollow sections. An airtight material 7 is fitted into the fitting groove 213b and is provided extending toward the sash 50 side. A sealing material 13 that abuts against the inner sash 3 is provided on the indoor side facing surface of the angle portion 213c.

[0019] The interior groove portion 21b is made of resin upper frame 213, which suppresses heat conduction between the interior and exterior sides of the upper frame 21, thereby improving the thermal insulation of the joinery 1. The angle portion 213c extends toward the X2 side and is embedded in the upper frame 121 such that the inner surface of the upper frame 121 and the inner surface of the angle portion 213c are substantially flush. In this disclosure, "substantially identical" and "substantially flush" include not only cases where they are completely identical or perfectly flush, but also cases where they are not completely identical or perfectly flush due to unavoidable factors such as dimensional tolerances, but can be considered functionally or visually substantially identical or substantially flush.

[0020] The lower frame 22 is divided into two parts in the depth direction: an outdoor frame portion 221 and an indoor frame portion 222. The outdoor frame portion 221 and the indoor frame portion 222 are integrally connected by a resin bridge material 26. The resin bridge material 26 can block heat transfer in the indoor-outdoor direction within the lower frame 22. This configuration improves the thermal insulation performance of the lower frame 22. The lower frame 22 has an adjustment member 20.

[0021] The indoor frame portion 222 is fixed to the indoor floor surface F1 via an angle material 223 with a substantially L-shaped cross-section. The outdoor frame portion 221 has a screen door rail 221a and an outdoor running rail 221b. The screen door rail 221a has a rail guide wall 2211 and a stepped portion 2212 that protrudes from the rail guide wall 2211 toward the X1 side. The bottom frame 62 for the screen door 6, which will be described later, is slidably mounted on the rail guide wall 2211. The outdoor running rail 221b can slide while supporting the sash 50 with rolling rollers 51. The outdoor running rail 221b constitutes the sash rail of this disclosure.

[0022] The screen door rail 221a constitutes the rail portion of the present disclosure. The rail portion of the present disclosure is a rail that supports the door body so that it can slide at a position that protrudes from the frame body towards the X1 side (outside). In the present disclosure, the door body includes not only screen doors but also shoji screens or storm shutters, and the rail portion refers to the rail that supports the door body located on the outermost side so that it can slide.

[0023] The indoor frame portion 222 has an indoor running rail 222a that protrudes upward. The indoor running rail 222a can be slid along while supporting the sliding door panel 50 by rolling rollers 52. An upward-opening space S1 is formed between the outdoor running rail 221b and the indoor running rail 222a. An upward-opening space S2 is formed between the indoor running rail 222a and the angle member 223. The indoor running rail 222a constitutes the sliding door rail of this disclosure.

[0024] The adjustment member 20 is a long member with a roughly concave cross-section that opens downwards and has an upper surface 20a. The width of the adjustment member 20 in the depth direction can be appropriately changed to match the placement location, and a wall portion hanging down from the upper surface 20a may be provided for reinforcement. The adjustment member 20 is placed in space S1 and space S2, and the upper surface 20a is positioned at approximately the same height as the upper ends of the outdoor running rail 221b and the indoor running rail 222a, so that the lower frame 22 can be adjusted to be approximately flush with the indoor floor surface F1 and the floor surface 111 of the outdoor structure 11. As a result, the lower frame 22 and the outdoor structure 11 form a continuous flat surface, and a barrier-free building component 1 can be constructed.

[0025] As shown in Figure 5, the vertical frame 23 is a vertical frame positioned on the right side of the door 1 when viewed from the X2 side. The vertical frame 23 is fixed to the vertical frame 122 via an angle member 231 with a roughly L-shaped cross section. The angle member 231 extends toward the X2 side and is embedded in the vertical frame 122 such that the inner surface of the vertical frame 122 and the inner surface of the angle member 231 are roughly flush.

[0026] The vertical frame 24 is a vertical frame positioned on the left side of the door 1 when viewed from the X2 side. The vertical frame 24 has a resin vertical frame 241 positioned on the inner circumferential surface on the X2 side. When the inner sash 3 is closed, the resin vertical frame 241 prevents the vertical frame 24 from being exposed to the X2 side, and when the inner sash 3 is fully open, the inner sash 3 abuts against the resin vertical frame 241, ensuring airtightness in the depth direction and improving the thermal insulation of the door 1. The vertical frame 24 is fixed to the vertical frame 122 via an angle material 242 with a roughly L-shaped cross section. The angle material 242 extends toward the X2 side and is embedded in the vertical frame 122 such that the inner circumferential surface of the vertical frame 122 and the inner circumferential surface of the angle material 242 are roughly flush.

[0027] As shown in Figures 2 and 5, the shoji screen 50 is a sliding window and consists of an inner shoji screen 3 and an outer shoji screen 4. The inner shoji screen 3 has a frame 30 and a facing material G1. The inner shoji screen 3 is a sliding door, and as shown in Figure 5, the opening formed by the frame 2 is opened by sliding the inner shoji screen 3 to the left when viewed from the X2 side.

[0028] As shown in Figures 2 and 5, the frame 30 is composed of an upper frame 31, a lower frame 32, an inner frame 33, and a door-edge frame 34. As shown in Figure 3, the upper frame 31 is composed of a metal frame 311 and a resin frame 312 connected together. The metal frame 311 is made of a profile obtained by extruding a metal such as aluminum, but is not limited to this. The resin frame 312 is made of a resin material with heat insulating properties and is provided on the visible surface on the X2 side. This configuration makes it possible to suppress heat transfer in the depth direction of the upper frame 31 and improve the heat insulating properties of the door 1.

[0029] The lower frame 32 is constructed by connecting a metal frame 321 and a resin frame 322. The metal frame 321 is made of a profile obtained by extruding a metal such as aluminum, but is not limited to this. The resin frame 322 is made of a resin material that has heat insulating properties and is provided on the visible surface on the X2 side. This configuration makes it possible to suppress heat transfer in the depth direction of the lower frame 32 and improve the heat insulating properties of the door 1. A door roller 52 is provided at the bottom of the metal frame 321, allowing the inner sash 3 to slide on the indoor running rail 222a.

[0030] As shown in Figure 5, the door frame 33 is constructed by connecting a metal frame 331 and a resin frame 332. The resin frame 332 is made of a resin material with heat insulating properties and is provided from the visible surface on the X2 side to the outer surface of the frame body 30. This configuration makes it possible to suppress heat transfer in the depth direction of the door frame 33 and improve the heat insulating properties of the door 1.

[0031] As shown in Figures 2 and 5, a pair of end caps 333, 333 are provided at the upper and lower ends of the interior frame 33. The end caps 333 are resin cap members with openings, and the pair of end caps 333, 333 are provided so that their openings face each other. The end cap 333 provided at the lower end can catch condensation that occurs on the interior frame 33 and prevent water from leaking into the room.

[0032] As shown in Figure 5, the door frame 34 is constructed by connecting a metal frame 341 and a resin frame 342. The metal frame 341 is made of a profile obtained by extruding a metal such as aluminum, but is not limited to this. The resin frame 342 is made of a resin material with heat insulating properties and is provided extending from the visible surface on the X2 side to the outer surface of the frame body 30. This configuration makes it possible to suppress heat transfer in the depth direction of the door frame 34 and improve the heat insulating properties of the door 1.

[0033] As shown in Figures 2 and 5, the facing material G1 is double-glazed glass, but the facing material of this disclosure is not limited to this. For example, single-glazed or triple-glazed glass may be used for the inner sash 3, or a panel member without glass may be used. The outer sash 4 has a frame body 40 and a facing material G1. The frame body 40 is composed of an upper frame 41, a lower frame 42, an outer sash 43, and a door edge frame 44. The upper frame 41, lower frame 42, and door edge frame 44 that make up the facing material G1 and frame body 40 correspond to the upper frame 31, lower frame 32, and door edge frame 34 that make up the facing material G1 and frame body 30 of the inner sash 3, respectively, so their explanation is omitted.

[0034] The outer frame 43 is constructed by connecting a metal frame 431 and a resin frame 432. The resin frame 432 is made of a resin material with heat insulating properties and is provided to cover a portion of the X2 side visible surface of the metal frame 431 and the X2 side visible surface of the facing material G1. This configuration improves the airtightness and waterproofness of the door 1 when the inner frame 33 of the inner sash 3 and the outer frame 43 of the outer sash 4 are combined with each other in the closed state.

[0035] As shown in Figures 2, 4, and 5, the screen door 6 is installed on the X1 side of the joinery 1 so as to be movable in the left-right direction on the screen door rail 221a of the lower frame 22. The screen door 6 is supported by the frame 2 so as to be slidable, in a position that protrudes from the frame 2 towards the X1 side. The screen door 6 is a surface material in which a screen is stretched inside a frame that is assembled around all four sides by an upper frame 61 for screen doors, a lower frame 62 for screen doors, and a pair of left and right vertical frames 63, 63 for screen doors.

[0036] As shown in Figure 4, the bottom frame 62 for the screen door is positioned to protrude from the frame 2 towards X1. Therefore, the outdoor structure 11 must be positioned at a predetermined distance from the screen door 6 so as not to interfere with the movement of the screen door 6. To maintain this predetermined distance, a mounting member 8 is detachably attached to the screen door rail 221a of the bottom frame 22. The mounting member 8 is made of an elastic material such as resin, but is not limited to this.

[0037] The mounting member 8 is a piece member with a substantially L-shaped cross-section, and as shown in Figure 5, it may be installed in three locations on the left, right, and center of the door 1 in the visible direction, or in four locations on the left, right, center of the inner sash 3, and center of the outer sash 4. The installation locations and number of mounting members 8 can be changed as appropriate depending on the site. The mounting member 8 has a rising portion 81 and a bottom portion 82. The rising portion 81 is installed adjacent to the end face 112 of the outdoor structure 11. The mounting member 8 is positioned below the screen door 6, and the lower part of the screen door bottom frame 62 is housed in a recess formed by the rising portion 81, the bottom portion 82, and the rail guide wall 2211 of the screen door rail 221a.

[0038] The bottom portion 82 is provided in contact with the rail guide wall 2211 and has a mounting hole 83 that opens towards the lower frame 22 and a contact portion 821. Fasteners such as screws are inserted through the mounting hole 83 from the X2 side of the rail guide wall 2211, and the mounting member 8 is fixed to the X1 side of the rail guide wall 2211. The contact portion 821 is provided at the X2 side end of the lower surface of the bottom portion 82. The contact portion 821 and the stepped portion 2212 of the screen door rail 221a come into contact, making it easy to position the mounting member 8 in the vertical direction and improving the ease of installation of the mounting member 8.

[0039] The mounting member 8 is provided on the lower frame 22, allowing the outdoor structure 11 and the screen door 6 to be held at a predetermined distance. By configuring the mounting member 8 as a separate part, it is not necessary to integrally provide a receiving part on the lower frame 22 to secure the distance from the outdoor structure. Therefore, the dimensions of the lower frame 22 in the depth direction can be reduced, thereby reducing construction costs such as manufacturing and transportation. Furthermore, by making the mounting member 8 a separate part, the lower frame 22 can be used in common regardless of whether or not there is an outdoor structure 11. This reduces the number of parts in the lower frame and improves on-site workability.

[0040] As shown in Figure 3, the airtight material 7 is provided on the inner circumferential surface of the upper frame 21 and is positioned to fit into the outdoor groove 21a and the indoor groove 21b, respectively. The airtight material 7 is provided between the frame 2 and the frame bodies 30 and 40. The airtight material 7 extends toward the upper frame 31 of the inner sash 3 and the upper frame 41 of the outer sash 4, respectively. The airtight material 7 is a long resin member that extends in the longitudinal direction of the upper frame 21. The airtight material 7 has a soft fin portion 71 that can abut against predetermined positions on the upper frame 31 and upper frame 41 facing the upper frame 21, and a guide portion 72 provided on the X2 side of the fin portion 71.

[0041] The predetermined position is the contact position where the fin portion 71 abuts against the upper frame 31 and the upper frame 41, respectively, and is set in a position that does not impair the airtightness or watertightness required for the joinery 1. In this embodiment, the predetermined position is the exterior end of each upper frame constituting the shoji screen. The predetermined position in this disclosure is not limited to this, and can be set as appropriate depending on the shape of the frame or frame, the performance required of the shoji screen, the positional relationship between the airtight line formed between the vertical frame and the vertical frame and the fin portion, etc.

[0042] The fin portion 71 is provided projecting from the inner circumferential surface of the upper frame 21 toward the shoji screen 50, and is arranged to extend toward the upper frame of each shoji screen 50. The fin portion 71 is formed of an elastically deformable material. As the material of the fin portion 71, for example, rubber, PVC, EPT, or other resin materials can be used, but are not limited to these.

[0043] The fin portion 71 has a fitted portion 711 and a contact piece 712 that protrudes from the fitted portion 711 toward the shoji screen 50. The fitted portion 711 is fitted into the fitting groove 211d of the outdoor frame portion 211, and the airtight material 7 is fixed to the upper frame 21. The contact piece 712 is bent toward the X1 side, and its tip contacts each of the upper frames of the shoji screen 50, thereby ensuring airtightness between the upper frame 21 and the shoji screen 50.

[0044] The guide portion 72 has a hanging piece 722 that protrudes downward from the fitted portion 711 of the fin portion 71, and a bottom piece 723 that is provided perpendicular to the lower end of the hanging piece 722 and connected to the contact piece 712. The bottom piece 723 is positioned on the upper frame side of each sash 50 relative to the inner circumferential surface of the frame 2, thereby reducing the gap between the upper frame 21 and each upper frame, and thus improving the thermal insulation of the joinery 1.

[0045] The guide portion 72 prevents the fin portion 71 from deforming toward the X2 side, and allows the fin portion 71 to contact a predetermined position on each upper frame of the sliding door 50. When the contact piece 712 of the fin portion 71 deforms or displaces toward the X2 side, it is biased toward the X1 side (outside) by the guide portion 72 and guided to a predetermined position on each upper frame. As a result, even with respect to vibrations or impacts associated with opening and closing the sliding door 50, the fin portion 71 can stably maintain its predetermined position and reliably contact each upper frame, thereby improving the airtightness and watertightness of the door 1.

[0046] Furthermore, by providing the guide portion 72, deformation of the fin portion 71 is suppressed, thus preventing misalignment of the airtight material 7 during the installation of the joinery 1. As a result, the fin portion 71 can be reliably brought into contact with the predetermined position on the upper frame of each sash 50, thereby improving the ease of installation of the joinery 1.

[0047] As shown in Figures 1 and 5, a restricting member 9 is provided on the lower frame 42 of the outer sliding door 4. The restricting member 9 is provided on the door edge frame 44 side of the lower frame 42. The restricting member 9 has a restricting part 91, a rotating shaft 92, a biasing part 93, and a housing part 94. The biasing part 93 is, for example, an elastic member such as a spring, but is not limited to this. The restricting part 91 is biased by the biasing part 93 and protrudes from the housing part 94 while rotating towards X2 on the rotating shaft 92. In this way, the restricting member 9 can restrict the sliding movement of the outer sliding door 4.

[0048] As shown in Figure 14, when the outer sliding door 4 is slid in the fully open direction, the door frame 44 of the outer sliding door 4 and the inner frame 33 of the inner sliding door 3 come into close proximity. If the outer sliding door 4 is fully opened in this state, there is a risk of the user's fingers being caught between the door frame 44 and the inner frame 33. The restricting member 9 prevents unintended finger pinching by restricting the sliding movement of the outer sliding door 4 just before it reaches the fully open position. As shown in Figure 15, the restricting part 91 is housed in the housing part 94, allowing the outer sliding door 4 to be fully opened.

[0049] This disclosure is not limited to the embodiments described above and may be modified as appropriate.

[0050] For example, while the joinery 1 includes an outdoor structure 11, the airtight seal 7 may be provided on joinery that does not include an outdoor structure 11. The airtight seal 7 can be provided on any type of joinery, as long as it includes a frame and a stile. Furthermore, the frame on which the airtight seal 7 can be provided is not limited to the upper frame; the airtight seal 7 can be provided on any frame that makes up the frame.

[0051] Furthermore, the airtight seal 7 is positioned such that the fin portion 71 faces X1 and the guide portion 72 faces X2, but this disclosure is not limited to this. For example, the fin portion 71 may be positioned on the X2 side and the guide portion 72 on the X1 side, with the positions in the depth direction reversed. In that case, the fin portion 71 is biased toward the X2 side (indoor side) by the guide portion 72 and guided to a predetermined position on the upper frame of each of the sliding doors 50.

[0052] Furthermore, as shown in Figure 16, the configuration of the airtight material may be changed. The airtight material 7A has a fin portion 71A and a base portion 73. The base portion 73 is configured in a substantially rectangular cylindrical shape and has a fitted portion 731, a pair of hanging pieces 732, 733 that protrude downward from both ends of the fitted portion 731, and a bottom piece 734 that connects the lower ends of the pair of hanging pieces 732, 733. The bottom piece 734 is positioned on the upper frame side of each sash 50 rather than the inner circumferential surface of the frame 2, thereby reducing the gap between the upper frame 21 and each upper frame, and thus improving the thermal insulation of the joinery 1. The fin portion 71A is provided extending from the hanging pieces 733 of the base portion 73. The fin portion 71A is bent toward X1, and its tip abuts against each upper frame of the sash 50, thereby ensuring airtightness between the upper frame 21 and the sash 50.

[0053] The airtight seal 7A is positioned within the frame 2, at least between the upper frame 21 and the upper frame 31 of the inner sash 3, and between the upper frame 21 and the upper frame 41 of the outer sash 4. The vertical dimensions of the base 73 and the length of the fin portion 71A are not limited and can be appropriately changed to match the depth of the outdoor groove portion and the indoor groove portion formed in the frame. For example, if the depth of the outdoor groove portion and the indoor groove portion is large, the distance between the frame and the frame portion will also be large, so the vertical dimensions of the base 73 and / or the length of the fin portion 71A may be increased.

[0054] This configuration allows the length of the fin portion 71A relative to the base portion 73 to be set arbitrarily. This makes it possible to accommodate frames of various dimensions and improves the workability of the joinery 1. Furthermore, compared to the case where the fin portion extends from the inner circumferential surface of the frame, the length of the fin portion 71A can be made shorter by providing the base portion 73, thereby further suppressing deformation of the fin portion.

[0055] Furthermore, although the mounting member 8 is fixed to the lower frame 22 using fasteners such as screws, the disclosure is not limited thereto. For example, when the mounting member 8 is used as a spacer when constructing an outdoor structure 11, the mounting member 8 may be temporarily fixed to the lower frame 22 using adhesive such as double-sided tape. In that case, the temporarily fixed mounting member 8 may be removed from the lower frame 22 after the installation of the outdoor structure 11 is completed.

[0056] [Second Embodiment] Next, a second embodiment of this disclosure will be described in detail with reference to the drawings. The differences between the second embodiment and the first embodiment are the configuration of the airtight material and mounting members, and the configuration of the upper frame into which the airtight material is fitted. Other configurations are the same as those of the first embodiment, so their description will be omitted.

[0057] As shown in Figures 6 and 7, the joinery 1B comprises a frame 2B, a sliding door 50, a screen door 6, and an airtight seal 7B. The frame 2B is constructed by framing an upper frame 21B, a lower frame 22, and vertical frames 23 and 24 (not shown) arranged in the left-right direction in a roughly rectangular shape. The difference between frame 2 and frame 2B is that in frame 2, one fitting groove 211d and one fitting groove 213b are provided for the outdoor groove 21a and the indoor groove 21b, respectively, while in frame 2B, two fitting grooves are provided for each. The other components are the same as those of frame 2, so their explanation is omitted.

[0058] The outdoor frame portion 211B of the upper frame 21B has a first fitting groove 211e that opens downward and is located on the X1 side, and a second fitting groove 211f that is located on the X2 side. The resin upper frame 213B has a first fitting groove 213d that is located on the X1 side and is formed on the inner circumference side of the upper surface portion 213a, and a second fitting groove 213e that is located on the X2 side.

[0059] As shown in Figures 6 and 7, the airtight material 7B is provided on the inner circumferential surface of the upper frame 21B and is positioned in the outdoor groove portion 21a and the indoor groove portion 21b, respectively. The airtight material 7B extends toward the upper frame 31 of the inner sash 3 and the upper frame 41 of the outer sash 4, respectively. The airtight material 7B is a long resin member that extends in the longitudinal direction of the upper frame 21B. As shown in Figure 7, the airtight material 7B has a soft fin portion 71B that can abut against predetermined positions on the upper frame 31 and upper frame 41 facing the upper frame 21B, and a guide portion 72B provided on the X1 side of the fin portion 71B.

[0060] The fin portion 71B has a fitted portion 711B and a contact piece 712B that protrudes from the fitted portion 711B toward the shoji screen 50. The fitted portion 711B is fitted into the first fitted groove 211e of the outdoor frame portion 211B and the first fitted groove 213d of the resin upper frame 213B, respectively, and the airtight material 7B is fixed to the upper frame 21B. The tip of the contact piece 712B is provided so as to be able to contact the upper frame of each shoji screen 50, thereby ensuring airtightness between the upper frame 21B and the shoji screen 50.

[0061] The guide portion 72B is provided bent toward X1 from the contact piece 712B, and an internal space is formed by the contact piece 712B and the guide portion 72B. The guide portion 72B suppresses deformation of the contact piece 712B toward X2, and allows the contact piece 712B to abut against predetermined positions on the upper frame of each of the sliding doors 50.

[0062] When the contact piece 712B deforms or displaces toward X2, it is pulled toward X1 (outside) by the tension of the guide portion 72B and guided to a predetermined position on each upper frame. As a result, even with respect to vibrations or impacts associated with opening and closing the sash 50, the contact piece 712B can stably maintain its predetermined position and reliably contact each upper frame, thereby improving the airtightness and watertightness of the door 1.

[0063] As shown in Figure 8, the mounting member 8B is detachably attached to the screen door rail 221a of the lower frame 22. The mounting member 8B is made of a metal such as aluminum, but is not limited to this. The difference between mounting member 8 and mounting member 8B is the type of fastener, such as a screw, and the direction in which the fastening part is inserted. Mounting member 8 is fixed to the lower frame 22 by a self-drilling screw, which is a fastener inserted from the X2 side of the rail guide wall 2211, while mounting member 8B is fixed to the lower frame 22 by a fastener inserted from the X1 side of the rail guide wall 2211. By using a self-drilling screw, pre-drilling of holes in the lower frame 22 is unnecessary, so mounting member 8B can be easily attached to the lower frame 22.

[0064] The mounting member 8B has a rising portion 81B, a bottom portion 82B, and a mounting hole 83B provided in the rising portion 81B. With this configuration, the mounting member 8B can be easily attached to the lower frame 22 even after the shoji screen 50 and the screen door 6 have been placed on the frame 2B, thereby improving the ease of installation of the joinery 1.

[0065] The bottom portion 82B has a contact portion 821B. The contact portion 821B is a notch provided at the X2 side end of the lower surface of the bottom portion 82B, and opens downward and toward the X2 side. The contact portion 821B and the stepped portion 2212 of the screen door rail 221a come into contact, allowing the mounting member 8B to be positioned in the vertical direction. This improves the ease of installation of the mounting member 8B.

[0066] This disclosure is not limited to the embodiments described above and may be modified as appropriate.

[0067] For example, the airtight material 7B is arranged such that the contact piece 712B bends toward X2 and the guide portion 72B bends toward X1, but the disclosure is not limited thereto. For example, the positions in the depth direction may be reversed so that the contact piece 712B bends toward X2 and the guide portion 72B bends toward X1. In that case, the contact piece 712B is pulled toward X2 (indoor side) by the tension of the guide portion 72B and guided to a predetermined position on each upper frame of the sliding door 50.

[0068] (Example 1 of airtight material) Furthermore, as shown in Figure 9, the airtight material may be composed of two members. The airtight material 7C has a fin portion 71C and a guide portion 72C located on the X2 side of the fin portion 71C. The fin portion 71C has a fitted portion 711B and a contact piece 712B that protrudes from the fitted portion 711B toward the shoji screen 50. The guide portion 72C has a fitted portion 724, a pair of hanging pieces 725, 725 that protrude downward from both ends of the fitted portion 724, and a bottom piece 726 that is provided perpendicular to the lower ends of the pair of hanging pieces 725, 725. The fitted portion 724 and the bottom piece 726 are provided to protrude in the depth direction more than the pair of hanging pieces 725, 725.

[0069] The bottom piece 726 is positioned on the upper frame side of each sash 50, rather than on the inner surface of the frame 2B, which reduces the gap between the upper frame 21B and each upper frame, thereby improving the thermal insulation of the door 1B.

[0070] The fitted portion 711B of the fin portion 71C is fitted and fixed into the first fitting groove 211e of the outdoor frame portion 211B and the first fitting groove 213d of the resin upper frame 213B, respectively. The fitted portion 724 of the guide portion 72C is fitted and fixed into the second fitting groove 211f of the outdoor frame portion 211B and the second fitting groove 213e of the resin upper frame 213B, respectively.

[0071] When the fin portion 71C deforms or displaces toward the X2 side, it is biased toward the X1 side (outside) by the bottom piece 726 of the guide portion 72C and guided to a predetermined position on each upper frame facing the upper frame 21B. As a result, even with respect to vibrations or impacts associated with opening and closing the sash 50, the fin portion 71C can stably maintain its predetermined position and reliably contact each upper frame, thereby improving the airtightness and watertightness of the joinery 1.

[0072] (Modification of airtight material 2) Furthermore, as shown in Figure 10, the guide portion may be positioned on the upper surface of the upper frame 31 of the inner sash 3 and the upper frame 41 of the outer sash 4, respectively. The airtight material 7D has a fin portion 71C and a guide portion 72D positioned on the X2 side of the fin portion 71C. The fin portion 71C is the same as in Modification 1, so its description is omitted.

[0073] As shown in Figures 10 to 13, the guide portion 72D is a piece member and is positioned on the X2 side of the fin portion 71C. The guide portion 72D has an insertion portion 738 and a protruding portion 739. The insertion portion 738 is inserted into the interior of the frames from the upper ends of the inner frame 33 and the outer frame 34 (not shown) of the inner sliding door 3, and from the upper ends of the outer frame 43 and the outer frame 44 (not shown) of the outer sliding door 4. In other words, guide portions 72D are provided at both upper ends in the left-right direction of a single sliding door.

[0074] The protruding portion 739 is positioned on the outer peripheral surface of the upper frame 31 of the inner sliding door 3 and the upper frame 41 of the outer sliding door 4, so as to protrude from the respective vertical frames. The protruding portion 739 has an inclined surface 739a that slopes downward toward X1 in the depth direction, and a pair of inclined portions 739c, 739c that extend in the visibility direction from a top portion 739b that extends in the depth direction on the inclined surface 739a.

[0075] When the fin portion 71C deforms or displaces toward the X2 side, its position is restricted toward the X1 side (outside) by the inclined surface 739a of the guide portion 72D, and it is guided to a predetermined position on each upper frame facing the upper frame 21B. As a result, even with respect to vibrations or impacts associated with opening and closing the sash 50, the fin portion 71C can stably maintain its predetermined position and reliably contact each upper frame, thereby improving the airtightness and watertightness of the joinery 1.

[0076] Furthermore, by providing a pair of inclined portions 739c, 739c extending in the visible direction on the protruding portion 739, the guide portion 72D can restrict the fin portion 71C from both the left and right directions even when the sliding door 50 is moved in both left and right directions. With this configuration, the fin portion 71C can be reliably guided to a predetermined position on each upper frame.

[0077] The protruding portion 739 only needs to be positioned on the outer circumferential surface of each upper frame, and its length in the depth direction and its length in the visible direction (left-right direction) can be changed as appropriate. For example, the depth length of the protruding portion 739 may be shorter than the depth length of each upper frame. Alternatively, the length of the protruding portion 739 in the visible direction may be increased so that the guide portion 72D is not a piece member but a long member extending in the longitudinal direction of the upper frame 21B. Furthermore, although the inclined portion 739c in this embodiment is formed to be curved in the outer circumferential direction, this disclosure is not limited thereto. For example, the inclined portion 739c may be formed to be flat.

[0078] [Third Embodiment] Next, a third embodiment of this disclosure will be described in detail with reference to the drawings. The difference between the second embodiment and the third embodiment is the configuration of the upper frame and the resin upper frame. The other configurations are the same as those of the first embodiment, so their description will be omitted.

[0079] As shown in Figure 17, the frame 2C is constructed by framing an upper frame 21C, a lower frame 22, and vertical frames 23, 24 (not shown) arranged in the left-right direction in a substantially rectangular shape. The upper frame 21C has an outdoor frame portion 211C, an indoor frame portion 212, and a resin upper frame 213C. The difference between the outdoor frame portion 211B and the outdoor frame portion 211C in the second embodiment is that a sealing material 13 is provided on the indoor visible wall 211c of the outdoor frame portion 211B, but a sealing material 13 is not provided on the indoor visible wall 211g of the outdoor frame portion 211C.

[0080] The resin upper frame 213C has an angle portion 213f with a substantially L-shaped cross-section that is positioned on the X2 side. The difference between the resin upper frame 213B and the resin upper frame 213C of the second embodiment is that in the resin upper frame 213B, a sealing material 13 is provided on the indoor-facing surface of the angle portion 213c, but in the resin upper frame 213C, a sealing material 13 is not provided on the indoor-facing surface of the angle portion 213f.

[0081] In this embodiment, the airtight material 7D ensures airtightness and watertightness between the upper frame 21 and the upper stiles of the sliding door 50. For this reason, the sealing material 13 that was provided between the upper frame 21C and the upper stiles of the sliding door 50 may be omitted. This reduces the number of parts and eliminates contact resistance between the sealing material 13 and the upper stiles 31 and 41, making it easier to open and close the sliding door 50 and improving the operability of the fixture.

[0082] This disclosure is not limited to the embodiments described above and may be modified as appropriate.

[0083] For example, in addition to the airtight material 7D, an airtight material 7B or an airtight material 7C may be provided on the upper frame 21C. Alternatively, the structure of the interior-facing wall 211c and the angle portion 213f may be applied to the upper frame 21 of the first embodiment, thereby omitting the sealing material 13.
