Description

[Technical Field]

[0001] The present disclosure relates to a closing component and a fitting. [Background Art]

[0002] Conventionally, in a fitting including sliding shoji screens, there has been known a structure in which a closing component is attached to a lower rail in order to prevent insects from entering through a gap between the shoji screen and the lower rail (see, for example, Patent Document 1). The closing component is, for example, an insect-proof component. The closing component attached to the lower rail described in Patent Document 1 is formed in a block shape.

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2008-127955 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] When the closing component is provided on the lower rail installed on the earthen floor, it is necessary to make the height of the lower rail installed on the earthen floor as small as possible. Therefore, when the closing component is formed in a block shape, it is difficult to secure a space for attaching the closing component to the lower rail, and when the closing component is attached to the lower rail, there is a possibility that it interferes with the opening and closing of the shoji screen. Therefore, there is a demand for a closing component that ensures closing performance and does not interfere with the opening and closing of the shoji screen.

[0005] An object of the present disclosure is to provide a closing component and a fitting that ensure closing performance and do not interfere with the opening and closing of shoji screens. [Means for Solving the Problem]

[0006] The present disclosure relates to a closing component disposed between a screen door rail and a shoji screen rail in a frame body, the closing component being formed in a flat plate shape. [Brief Description of the Drawings]

[0008] Embodiments of this disclosure will be described in detail below with reference to the drawings. In this specification, "depth direction" refers to the direction along the interior-exterior direction of the joinery. "Face direction" refers to the direction along the surface direction of the facing material of the joinery, and is perpendicular to the depth direction. "Face surface" refers to the exterior and interior faces of the joinery, respectively, and "depth surface" refers to the surface of the joinery that extends in the interior-exterior direction. In the drawings, the exterior side of the joinery is referred to as "exterior side X1," and the interior side of the joinery is referred to as "interior side X2." The horizontal direction when the joinery is viewed from the front is referred to as "left and right."

[0009] As shown in Figures 1 and 2, the joinery 1 of this embodiment comprises a frame 2, two sliding doors 3 and 4 arranged within the frame 2, a screen door 5 (see Figures 3 and 4), and a locking device 6 for locking and unlocking the sliding doors 3 and 4. As shown in Figures 3 and 4, the joinery 1 is placed in an opening in the building structure 100. The two sliding doors 3 and 4 are configured to slide horizontally within the frame 2 and are sliding doors that can be opened and closed by sliding them. The joinery 1 constitutes a sliding window. The joinery 1 of this embodiment is, for example, a sliding door used in an earthen floor. An earthen floor is, for example, an area indoors where there is a floor, and is filled with mortar at a position one step lower than the floor. In Figures 1 and 2, the screen door 5 is not shown.

[0010] As shown in Figures 3 and 4, the frame 2 is fitted into the opening of the building structure 100. As shown in Figures 1 to 4, the frame 2 is constructed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23 and 24 in a rectangular shape. The two sashes 3 and 4 consist of an outer sash 3 positioned on the exterior side X1 on one side of the frame 2 in the left-right direction (left side in Figure 1), and an inner sash 4 positioned on the interior side X2 on the other side of the frame 2 in the left-right direction (right side in Figure 1).

[0011] As shown in Figures 1 and 2, the upper frame 21 extends in the left-right direction (lateral direction). As shown in Figure 3, the upper frame 21 has a composite structure in which a resin cover material 215 (resin part) made of resin is attached to the inner circumference of the end X2 on the indoor side of the upper frame body 210. Therefore, it has excellent heat insulation and condensation prevention properties. The upper frame body 210 is positioned on the outdoor side X1 of the upper frame 21. The resin cover material 215 is attached to the indoor side X2 portion of the upper frame body 210.

[0012] The upper frame body 210 is divided into two parts in the depth direction: an outdoor frame member 211 and an indoor frame member 212. The outdoor frame member 211 and the indoor frame member 212 are each made of extruded profiles formed by extruding a metal material such as aluminum in the longitudinal direction. A bridge member 213 is placed between the outdoor frame member 211 and the indoor frame member 212. The outdoor frame member 211 and the indoor frame member 212 are integrally connected by the bridge member 213. The bridge member 213 is made of a material with heat insulating properties such as resin and blocks the transfer of heat from the outdoor frame member 211 to the indoor frame member 212 in the upper frame 21.

[0013] As shown in Figure 3, the outdoor frame member 211 includes an outdoor hollow frame section 2111 and an indoor hollow frame section 2112 arranged side by side from the outdoor side X1 to the indoor side X2 at the top, a protruding plate 2113 projecting upward from the indoor side X2 end of the indoor hollow frame section 2112, an outdoor rail 210a for the outer sash 3 projecting downward from the lower surface of the connection portion between the outdoor hollow frame section 2111 and the indoor hollow frame section 2112, and a screen door rail 210c for the screen door 5 projecting downward from the outdoor side X1 end of the lower surface of the outdoor hollow frame section 2111. The protruding plate 2113 is fixed to the building frame 100 by screws SC11.

[0014] The indoor frame member 212 has a depth-extending portion 2121 that extends in the depth direction on the outdoor side X1, an indoor downward-projecting portion 2122 that protrudes downward from the indoor side X2 end of the depth-extending portion 2121, and an indoor rail 210b for the inner sash 4 that protrudes downward from the outdoor side X1 end of the depth-extending portion 2121.

[0015] The outdoor rail 210a is provided on the outdoor side X1 of the upper frame 21, and the indoor rail 210b is provided on the indoor side X2 of the upper frame 21. The outdoor rail 210a and the indoor rail 210b guide the upper parts of the outer sash 3 and inner sash 4, which are housed inside the frame 2. The screen door rail 210c, provided at the end of the outdoor side X1 of the outdoor frame member 211, is provided at the end of the outdoor side X1 of the upper frame 21 and guides the upper part of the screen door 5. The outdoor rail 210a, the indoor rail 210b, and the screen door rail 210c extend along the entire length of the upper frame 21 in the left-right direction.

[0016] A resin rail cover 2114 is installed between the pair of outdoor rails 210a and indoor rails 210b of the upper frame 21. The rail cover 2114 is positioned across the lower surface of the outdoor frame member 211 and the lower surface of the bridge member 213 so as to substantially shield the space between the outdoor rails 210a and indoor rails 210b of the upper frame 21.

[0017] A resin cover material 215 is attached to the lower part of the end of the indoor side X2 of the indoor side frame member 212 of the upper frame body 210. The portion of the resin cover material 215 that protrudes to the indoor side X2 is fixed to the frame member 120 of the indoor side X2 by screws SC12.

[0018] In the upper frame 21, exterior wall material 110 is installed on the exterior side X1 of the building frame 100. A sealant 111 is filled into the gap between the exterior wall material 110 and the upper frame 21. A frame member 120 is attached to the interior side X2 of the upper frame 21. The frame member 120 extends from the interior side X2 of the upper frame 21 toward the interior side X2. On the interior side X2 of the building frame 100, interior wall material 130 is installed on the outer perimeter of the frame member 120.

[0019] As shown in Figures 1 and 2, the lower frame 22 extends in the left-right direction (lateral direction). As shown in Figures 5 and 6, the lower frame 22 has an aluminum lower frame body 25, a stainless steel rail member 26 (stainless steel member) made of stainless steel, a first end part 81, a second end part 82, a closing part 83, and an airtight part 84. The lower frame 22 has a structure in which the stainless steel rail member 26, the first end part 81, the second end part 82, the closing part 83, and the airtight part 84 made of stainless steel are attached to the upper surface of the aluminum lower frame body 25. The first end part 81, the second end part 82, the closing part 83, and the airtight part 84 are, for example, made of resin.

[0020] The lower frame body 25 is formed in a stepped shape, with the outdoor side X1 portion being lower than the indoor side X2 portion. When the lower frame body 25 is cut in the direction along the depth, the cross section has a lower step portion 251 formed on the outdoor side X1, a step 254 positioned at the indoor side X2 end of the lower step portion 251, a middle step portion 252 positioned at the center of the lower frame body 25 in the indoor-outdoor direction, positioned on the indoor side X2 of the lower step portion 251 via the step 254, a step 255 positioned at the indoor side X2 end of the middle step portion 252, and an upper step portion 253 positioned on the indoor side X2 of the middle step portion 252 via the step 255.

[0021] As shown in Figure 3, the lower frame 22 is embedded in the floor structure 140 with anchors 150 attached to its lower part. The construction procedure for installing the lower frame 22 involves attaching anchors 150 to its lower part, and then embedding the lower frame 22 into the floor structure 140 with the anchors 150 attached to its lower part. As shown in Figure 3, the floor structure 140 is formed in a stepped manner, with the exterior side X1 being lower than the interior side X2.

[0022] As shown in Figures 5 and 6, the stainless steel rail member 26 has an outdoor stainless steel member 261 positioned on the outdoor side X1 and a central stainless steel member 262 positioned on the indoor side X2 of the outdoor stainless steel member 261. The outdoor stainless steel member 261 is positioned on the upper surface of the lower section 251 of the outdoor side X1 of the lower frame body 25. The central stainless steel member 262 is positioned on the upper surface of the middle section 252 on the central side in the indoor-outdoor direction of the lower frame body 25. The outdoor stainless steel member 261 and the central stainless steel member 262 are fixed to the upper surface of the lower frame body 25 with screws.

[0023] As shown in Figure 6, the outdoor stainless steel member 261 and the central stainless steel member 262 are formed to extend in the left-right direction, which is the longitudinal direction of the lower frame 22. The left-right lengths of the outdoor stainless steel member 261 and the central stainless steel member 262 are formed to be shorter than the left-right length of the lower frame body 25, and the positions of both ends of the stainless steel rail member 26 in the left-right direction are positioned further inward than the ends of the lower frame body 25.

[0024] As shown in Figures 5 and 6, the outdoor stainless steel member 261 has a bottom plate portion 2611, an outdoor rail 220a, and a screen door rail 220c. The bottom plate portion 2611 is formed in a plate shape with thickness in the vertical direction, width in the indoor-outdoor direction, and extends in the left-right direction. The outdoor stainless steel member 261 is fixed with screws to the upper surface of the lower section 251 of the lower frame body 25. The outdoor rail 220a is formed in a plate shape that protrudes upward from the indoor side X2 end of the bottom plate portion 2611. The outdoor rail 220a is formed from a double plate material in which the plate material is folded back at the upper end and overlapped, and is formed in a plate shape that protrudes upward from the outdoor side X1 end of the bottom plate portion 2611.

[0025] The central stainless steel member 262 has a lower plate portion 2621 and an indoor rail 220b. The lower plate portion 2621 is formed in a plate shape with thickness in the vertical direction, width in the indoor-outdoor direction, and extends in the left-right direction. The central stainless steel member 262 is fixed with screws to the upper surface of the middle section 252 of the lower frame body 25. The indoor rail 220b is formed in a plate shape that protrudes upward from the indoor side X2 end of the lower plate portion 2621, and is formed by a double plate material in which the plate material is folded back and overlapped at the upper end.

[0026] The outdoor rail 220a, the indoor rail 220b, and the screen door rail 220c are formed extending in the left-right direction of the lower frame 22. The outdoor rail 220a is positioned on the outdoor side X1 of the lower frame 22 and protrudes upward. The indoor rail 220b is positioned on the indoor side X2 of the lower frame 22 and protrudes upward. The outdoor rail 220a and the indoor rail 220b guide the lower parts of the outer sash 3 and inner sash 4, which are housed inside the frame 2. The screen door rail 220c is positioned at the end of the outdoor side X1 of the lower frame 22 and protrudes upward. The screen door rail 220c guides the lower part of the screen door 5.

[0027] As described above, by providing a stainless steel rail member 26 on the upper surface of the aluminum lower frame body 25, which has an outdoor rail 220a, an indoor rail 220b, and a screen door rail 220c formed on it, the strength of the rails can be improved compared to forming each rail on the aluminum lower frame body 25.

[0028] As shown in Figure 6, the upper surface of the lower frame 22 is provided with a first end component 81, a second end component 82, a closing component 83, and an airtight component 84. Details of the first end component 81, the second end component 82, the closing component 83, and the airtight component 84 will be described later.

[0029] As shown in Figures 1 and 2, the vertical frames 23 and 24 extend in the vertical direction. As shown in Figure 4, the vertical frames 23 and 24 have a composite structure in which resin indoor-side resin cover materials 232 and 242 are attached to the inner circumference of the ends X2 on the indoor side of the metal frame bodies 231 and 241, which are the vertical frame bodies. Therefore, the vertical frames 23 and 24 have excellent heat insulation and condensation prevention properties.

[0030] The metal frames 231 and 241 are made of extruded profiles formed by extruding a metal material such as aluminum in the longitudinal direction. The metal frames 231 and 241 have a depth-oriented extension portion 2311 and 2411 that extends in the depth direction, a projection portion 2312 and 2412 that protrudes to the outer circumference in the left-right direction midway along the depth-oriented extension portion 2311 and 2411, an outdoor-side plate portion 2313 and 2413 formed at the outdoor-side end X1 of the depth-oriented extension portion 2311 and 2411 and extending in the left-right direction, and an indoor-side end projection portion 2314 and 2414 formed at the indoor-side end X2 of the depth-oriented extension portion 2311 and 2411 and protruding inward in the left-right direction.

[0031] The vertical frames 23 and 24 are fixed to the building structure 100 by screws SC31 and SC41 at the protruding parts 2312 and 2412.

[0032] The indoor resin cover materials 232 and 242 are attached to the end portions of the indoor side X2 of the metal frames 231 and 241. At the portions attached to the end portions of the indoor side X2 of the metal frames 231 and 241, the indoor resin cover materials 232 and 242 are fastened together with the end portions of the indoor side X2 of the metal frames 231 and 241 using screws SC32 and SC42, and are fixed to the building structure 100.

The lower end of the facing material 36 is positioned in the upper side material receiving portion 35a. The upper end of the facing material 37 is positioned in the lower side material receiving portion 35b.

[0046] As shown in Figures 10 to 12, the vertical frame 33 on the door edge side has a metal profile 331 (first profile) made of a material such as aluminum and a resin profile 332 (second profile). The metal profile 331 (first profile) and the resin profile 332 (second profile) are arranged in this order from the exterior side X1 to the interior side X2 in the depth direction (indoor-outdoor direction) and engage with each other. The metal profile 331 (first profile) is an aluminum profile, and the resin profile 332 (second profile) is a resin profile.

[0047] As described above, the intermediate crossbar 35 has a metal profile 351 (first profile) made of a metal material such as aluminum, and a resin profile 352 (second profile). The metal profile 351 (first profile) and the resin profile 352 (second profile) are arranged in this order from the outdoor side X1 to the indoor side X2 in the depth direction (indoor-outdoor direction) and engage with each other. As shown in Figure 9, a pair of L-shaped projections 3523 that project in an L-shape from the outdoor side X1 surface of the resin profile 352 to the outdoor side X1 engage with a pair of protrusions 3511b formed at both ends in the vertical direction on the indoor side X2 of the hollow frame portion 3511 of the metal profile 351 of the intermediate crossbar 35. The metal profile 351 (first profile) is an aluminum profile, and the resin profile 352 (second profile) is a resin profile.

[0048] When the intermediate rail 35 is assembled to the vertical frame 33 on the door edge side in the vertical direction (longitudinal direction), end caps 7 are provided at the left-right (longitudinal direction) ends of the resin profile 352 of the intermediate rail 35, as shown in Figures 12 and 13. The end caps 7 are formed from, for example, a resin material.

[0049] As shown in Figure 10, the left-right ends 351a of the metal profile 351 of the middle rail 35 are positioned in contact with the metal profile 331 of the vertical frame 33 on the door edge side and are fixed to the metal profile 331 of the vertical frame 33 on the door edge side by a fixing member 33a. The fixing member 33a is a fastening member that fastens and secures, and an example of a fastening member is a screw. As shown in Figure 11, the left-right ends 352a of the resin profile 352 of the middle rail 35 are fixed in contact with the resin profile 332 of the vertical frame 33 on the door edge side via end caps 7.

[0050] As shown in Figures 10, 11, and 14, the metal profile 351 of the middle rail 35 is fixed with its left and right ends 351a being swallowed by the receiving portion 331a of the metal profile 331 of the vertical frame 33 on the door edge side. The resin profile 352 of the middle rail 35 is engaged and fixed by an end cap 7 that abuts against the inner circumferential end face 332a of the resin profile 332 of the vertical frame 33 on the door edge side.

[0051] As shown in Figures 15 and 16, the end cap 7 has an insertion portion 71, a cover portion 72 (end face portion), a pair of guide groove portions 73, a projection portion 74, and a claw portion 75.

[0052] The insertion portion 71 is formed at the inner circumference end of the end cap 7 in the left-right direction, is formed in a cylindrical shape that protrudes toward the middle crossbar 35, and extends in the vertical direction. The insertion portion 71 is inserted into the central hollow frame portion 3521 which is located in the vertical center of the resin profile 352 of the middle crossbar 35.

[0053] The cover portion 72 is connected to the outer peripheral ends of the insertion portion 71 in the left-right direction. The cover portion 72 has width in the depth direction and extends in the vertical direction, and covers the outer peripheral end faces of the resin profile 352 of the middle crossbar 35 in the left-right direction.

[0054] As shown in Figure 16, the cover portion 72 includes a vertical plate portion 722 having an end face 721 facing the outer circumference in the left-right direction, an upper wall 723 protruding inward from the upper end of the vertical plate portion 722, a lower wall 724 protruding inward from the lower end of the vertical plate portion 722, a side wall 725 protruding inward from the indoor side X2 end of the vertical plate portion 722, an upper engaging wall 726 formed below the upper wall 723, and a lower engaging wall 727 formed above the lower wall 724.

[0055] The vertical plate portion 722 is formed in a plate shape with thickness in the left-right direction, width in the depth direction, and extends in the vertical direction. The end face 721, which is the depth surface on the outer circumference side of the cover portion 72, abuts against the inner circumference end face 332a of the resin profile 332 of the vertical frame 33 on the door edge side, as shown in Figure 11. The claw portion 75 is located on the outer circumference side of the cover portion 72 and is engaged with the resin profile 332 of the vertical frame 33 on the door edge side. As a result, the claw portion 75 of the end cap 7 engages with the resin profile 332 of the vertical frame 33 on the door edge side, and the left-right ends of the resin profile 352 of the middle rail 35 are fixed to the resin profile 332 of the vertical frame 33 on the door edge side via the end cap 7.

[0056] The upper engaging wall 726 and the lower engaging wall 727 are inserted into a pair of end hollow frame portions 3522 formed at both the vertical ends of the resin profile 352 of the middle rail 35 when the end cap 7 is attached to the middle rail 35. The upper wall 723, the lower wall 724 and the side wall 725 cover the outer surfaces of the left and right ends of the resin profile 352 of the middle rail 35.

[0057] As shown in Figures 14 and 15, the pair of guide grooves 73 are positioned vertically spaced apart in the middle of the cover portion 72 and protrude outward from the outer peripheral portion of the cover portion 72. Each of the pair of guide grooves 73 has an L-shaped cross-section when cut vertically. When the end cap 7 is attached to the middle rail 35, the pair of guide grooves 73 engage with a pair of projections 3511b on the indoor side X2 of the hollow frame portion 3511 of the metal profile 351 of the middle rail 35.

[0058] As shown in Figures 15 and 16, the projection 74 is positioned between a pair of guide grooves 73 in the vertical direction and is formed in a claw shape that protrudes toward the outdoor side X1. When the end cap 7 is attached to the middle rail 35, the projection 74 engages with a locking hole 3511a formed in the vertical plate 3511c on the indoor side X2 of the hollow frame portion 3511 of the metal profile 351 of the middle rail 35.

[0059] As shown in Figures 15 and 16, the claw portion 75 is positioned between a pair of guide groove portions 73 in the vertical direction and is formed at the end of the pair of guide groove portions 73 on the cover portion 72 side. The claw portion 75 is formed to protrude in a triangular shape in cross-section on the indoor side X2. As shown in Figure 11, when the end cap 7 is attached to the vertical frame 33 on the door edge side, the claw portion 75 engages with the projection 332b that protrudes to the outdoor side X1 at the inner circumference end of the resin profile 332 of the vertical frame 33 on the door edge side. As a result, the left and right ends of the resin profile 352 of the middle rail 35 are fixed to the resin profile 332 of the vertical frame 33 on the door edge side via the end cap 7.

[0060] When assembling the intermediate rail 35 to the vertical frame 33 on the door edge side in the middle of its vertical direction, the end caps 7 are attached to the left and right ends of the resin profile 352 of the intermediate rail 35, as shown in Figures 15 and 16. Then, as shown in Figures 12 and 13, the left and right ends of the intermediate rail 35 with the end caps 7 attached are inserted to the vertical frame 33 on the door edge side in the middle of its vertical direction, and as shown in Figure 10, the left and right ends 351a of the metal profile 351 of the intermediate rail 35 are brought into contact with the receiving portion 331a of the metal profile 331 of the vertical frame 33 on the door edge side, and fixed to the metal profile 331 of the vertical frame 33 on the door edge side by the fixing member 33a. In this way, when fixing the vertical frame 33 on the door edge side and the intermediate rail 35, the members to be fixed by the fixing member 33a can be firmly fixed without the need for any intermediate parts. On the other hand, by fixing the left and right ends of the resin profile 352 of the middle rail 35 via the end cap 7, it becomes unnecessary to cut out the vertical frame 33 on the door edge side in order to fix the resin profile 352 of the middle rail 35 to the resin profile 332 of the vertical frame 33 on the door edge side. This improves ease of installation.

[0061] As shown in Figures 17 and 18, the locking device 6 is installed midway between the outer meeting stile 34 of the outer sash 3 and the inner meeting stile 44 of the inner sash 4 in the vertical direction. As shown in Figures 19 and 20A, the locking device 6 is installed straddling the outer meeting stile 34 of the outer sash 3 and the inner meeting stile 44 of the inner sash 4. As shown in Figures 20A and 20B, the locking device 6 can be locked and unlocked from the indoor side X2 by operating the operating part 63 of the indoor side lock part 61 installed on the inner meeting stile 44 of the inner sash 4. The locking device 6 can also be locked and unlocked from the outdoor side X1 by inserting a key (not shown) into the keyhole 681 of the cylinder part 68 of the cylinder lock 66 installed on the outer meeting stile 34 of the outer sash 3 and operating it. Figure 20A shows the unlocked state of the locking device 6, and Figure 20B shows the locked state of the locking device 6.

[0062] As shown in Figures 19, 20A, and 20B, the locking device 6 comprises an indoor locking unit 61 positioned on the inner meeting stile 44 of the inner sash 4 on the indoor side X2, and a cylinder lock 66 (outdoor locking unit) positioned on the outer meeting stile 34 of the outer sash 3 on the outdoor side X1. The indoor locking unit 61 has an indoor lock body 62 (lock body) and an operating unit 63.

[0063] The indoor lock body 62 is installed inside the inner meeting frame 44 of the inner sliding door 4. The indoor lock body 62 locks and unlocks the outer sliding door 3 and the inner sliding door 4. The indoor lock body 62 has a mounting plate 621, an indoor lock support part 622, and an indoor lock hook part 623.

[0064] As shown in Figure 22, the mounting plate 621 is formed in a plate shape and extends in the vertical direction. As shown in Figure 20A, the mounting plate 621 is attached to the outdoor side X1 surface of the inner meeting frame 44. As shown in Figure 22, the indoor side lock support part 622 is formed in a box shape that extends in the vertical direction and is fixed to the indoor side X2 of the mounting plate 621. An opening 6221 that opens toward the indoor side X2 is formed near the vertical center of the indoor side lock support part 622, and an opening locking part 6222 that opens toward upward and toward the indoor side X2 is formed in the lower part in the vertical direction. When attaching the operating part 63 to the indoor side lock body part 62, the outdoor side X1 end of the shaft part 643 (described later) of the sliding part 64 of the operating part 63 is inserted into the opening 6221. When attaching the operating unit 63 to the indoor side lock body 62, the outdoor side X1 end of the lower support projection 653 (described later) of the fixing part 65 of the operating unit 63 is locked to the opening locking part 6222.

[0065] The operating unit 63 is provided on the inner meeting frame 44 of the inner sliding door 4. The operating unit 63 operates the locking and unlocking of the indoor side lock body 62. As shown in Figures 21 and 22, the operating unit 63 has a sliding movement part 64 and a fixing part 65 that fixes the sliding movement part 64 to the inner meeting frame 44 of the inner sliding door 4.

[0066] As shown in Figures 17 and 20A, the sliding portion 64 extends substantially flat on the surface 440 (visible surface) of the interior side X2 of the interior meeting stile 44. "Substantially flat" means that the surface of the sliding portion 64 as a whole follows the surface 440 of the interior meeting stile 44. It is not limited to a flat plate shape; it may also be rectangular or other shapes, and may have irregularities or curved surfaces in some parts.

[0067] As shown in Figures 17, 20A, and 20B, the sliding mechanism 64 is movable along the surface 440 (visible surface) of the interior side X2 of the interior meeting stile 44. In this case, the interior lock body 62 locks and unlocks the exterior sash 3 and the interior sash 4 in conjunction with the movement of the sliding mechanism 64.

[0068] As shown in Figures 21 to 26, the sliding part 64 is positioned exposed on the indoor side X2 and has a flat operating surface 641 that extends vertically along the surface 440 (visible surface) of the indoor side X2 of the inner meeting frame 44, a rear projection 642 that protrudes from the rear of the outdoor side X1 of the operating surface 641 and extends vertically to the outdoor side X1, a shaft 643 that extends from the portion of the rear projection 642 on the outdoor side X1 to the outdoor side X1, and the upper end of the rear projection 642 It has a Y-shaped engaging portion 644 (first engaging portion on the sliding part side) that protrudes upward in a Y-shape and engages with the first engaging portion 6511 (described later) of the sliding part fixing portion 651 of the fixing portion 65, and a second engaging portion 645 on the sliding part side that protrudes on both the left and right sides at the upper and lower parts of the rear protruding portion 642 and engages with the second engaging portion 6512 (described later) of the sliding part fixing portion 651 of the fixing portion 65.

[0069] The operating surface 641 has a vertically elongated shape and extends in the vertical direction. When viewed from the front of the indoor side X2, the operating surface 641 is formed in a vertically elongated, approximately rectangular shape. The operating surface 641 is provided on the end side of the shaft 643 on the indoor side X2 in the longitudinal direction via a rear projection 642. As shown in Figures 27 and 28, the operating surface 641 has thickness in the depth direction.

[0070] As shown in Figures 27 and 28, the operating surface 641 is formed in a thin, flat shape, and the thickness L1 of the operating surface 641 in the depth direction is, for example, about 7 mm.

[0071] Furthermore, the gap L2 between the operating surface 641 of the sliding section 64 and the surface 440 of the inner meeting stile 44 is approximately 0.8 mm. This gap L2 between the operating surface 641 of the sliding section 64 and the surface 440 of the inner meeting stile 44 prevents the back surface (outside X1) of the operating surface 641 of the sliding section 64 from rubbing against the surface 440 of the inner meeting stile 44 during operation, while also preventing the gap L2 between the operating surface 641 of the sliding section 64 and the surface 440 of the inner meeting stile 44 from being too wide, thereby improving the aesthetic appearance.

[0072] As shown in Figures 27 and 28, the operating surface portion 641 of the sliding movement portion 64 is exposed on the surface 440 of the inner meeting frame 44, while the portion of the sliding movement portion 64 other than the sliding movement portion is hidden inside the inner meeting frame 44. The surface 440 of the inner meeting frame 44 extends around the periphery of the operating surface portion 641 of the sliding movement portion 64.

[0073] The operating surface portion 641 has a surface portion 6411 exposed to the indoor side X2, a base portion 6413 positioned on the inner meeting stile 44 side, and an intermediate portion 6412 positioned between the surface portion 6411 and the base portion 6413. The surface portion 6411, the intermediate portion 6412, and the base portion 6413 are arranged in this order from the indoor side X2 to the outdoor side X1. The thickness of the surface portion 6411, the intermediate portion 6412, and the base portion 6413 in the depth direction is formed to increase in this order.

[0074] As shown in Figures 27 and 28, the operating surface portion 641 has a surface-side inclined curved side portion 6411a (side portion) and a base-side inclined curved side portion 6413a (side portion). The surface-side inclined curved side portion 6411a is formed on the side of the surface portion 6411, inclined and curved so as to move from the inside to the outer edge, it moves from the indoor side X2 to the outdoor side X1. The base-side inclined curved side portion 6413a is formed on the side of the base portion 6413, inclined and curved so as to move from the inside to the outer edge, it moves from the outdoor side X1 to the indoor side X2. The intermediate portion 6412 has a linear side portion 6412a that extends linearly parallel to the depth direction. The surface-side inclined curved portion 6411a, the base-side inclined curved portion 6413a, and the straight portion 6412a are formed over the entire circumferential area of ​​the operating surface portion 641.

[0075] The surface-side inclined curved side portion 6411a is inclined at a slight angle with respect to the indoor-side X2 surface of the surface portion 6411, as it approaches the outer edge of the indoor-side X2 surface of the surface portion 6411. The base-side inclined curved side portion 6413a is inclined at a larger angle than the surface-side inclined curved side portion 6411a with respect to the outdoor-side X1 surface of the base portion 6413, as it approaches the outer edge of the outdoor-side X1 surface of the base portion 6413.

[0076] As shown in Figures 17 and 29, the operating surface 641 has a display window 6414 (lock / unlock indicator) on the lower side of its surface. The display window 6414 displays the locked / unlocked status of the indoor lock body 62. The display window 6414 is formed by a through-hole that extends in the left-right direction and penetrates the operating surface 641 in the thickness direction. When the sliding part 64 moves in the vertical direction, the display window 6414 displays the first display section 653a and the second display section 653b, which are arranged vertically at the bottom of the indoor side X2 surface of the fixing part 65 located on the back side of the sliding part 64, as shown in Figures 25 and 29. The display contents of the first display section 653a and the second display section 653b are visually different, and may be different colors, different characters, different patterns, or different pictograms. Furthermore, the display content of the first display unit 653a and the second display unit 653b may be different in appearance, or they may be different in touch. For example, they may be different in appearance by using raised dots like Braille, or they may be different in touch by using a rough texture and a smooth texture.

[0077] For example, when the display contents of the first display unit 653a and the second display unit 653b are to be different colors, for example, as shown in the left diagram of Figure 29, the display content of the first display unit 653a shown in the display window 6414 when unlocked can be set to orange, and as shown in the right diagram of Figure 29, the display content of the second display unit 653b shown in the display window 6414 when locked can be set to black. In this case, when unlocked, the bright orange color makes it easy to see and makes it more noticeable from a distance, thus attracting attention from a security standpoint. Also, for example, when locked, a dark color such as black can be used to make it less noticeable and improve the design.

[0078] As shown in Figures 20A, 21, and 22, the shaft portion 643 is formed in a rectangular cylindrical shape extending in the depth direction (indoor-outdoor direction). The shaft portion 643 extends from the rear projection 642 on the outdoor side X1 of the operating surface portion 641 to the outdoor side X1 in the depth direction. The end of the shaft portion 643 on the outdoor side X1 in the longitudinal direction is connected to the indoor lock body portion 62 by being inserted into the opening 6221 of the indoor lock support portion 622 of the indoor lock body portion 62 when the operating portion 63 is attached to the indoor lock body portion 62. Ribs 6431 extending in the depth direction are formed on the upper and lower surfaces of the shaft portion 643.

[0079] As shown in Figure 22, the fixing portion 65 has a rectangular parallelepiped-shaped slide-side fixing portion 651 fixed to the sliding moving portion 631, a frame-side fixing portion 652 fixed to the inner meeting frame 44, and a lower support projection portion 653. The outdoor-side end X1 of the lower support projection portion 653 is locked to the opening locking portion 6222 of the indoor-side lock support portion 622 of the indoor-side lock body portion 62 when the operating portion 63 is attached to the indoor-side lock body portion 62.

[0080] As shown in Figures 23 to 25, the slide-side fixing portion 651 has a first engaging portion 6511 (see Figure 25) which is formed in a horizontal plate shape on the upper side of the interior of the slide-side fixing portion 651, spaced apart in the left-right direction, and engages with the Y-shaped engaging portion 644 of the slide-moving portion 64, and a second engaging portion 6512 (see Figures 23 and 25) which is formed midway in the vertical direction inside the interior of the slide-side fixing portion 651 and engages with the second engaging portion 645 on the slide-moving portion side of the slide-moving portion 64. The slide-side fixing portion 651 has a plurality of claw-shaped engaging portions 6513 (engaging portions) (see Figures 23, 28, etc.) formed on the upper and lower exterior of the slide-side fixing portion 651 that engage with both lateral ends of the opening 44a (see Figure 17) of the inner meeting frame 43, and a hook-engaging groove 6514 (engaging portion) (see Figures 23, 30, etc.) formed on the indoor side X2 of the lower end of the lower support projection 653 that opens downward and engages with the lower end of the opening 44a (see Figure 17) of the inner meeting frame 43.

[0081] As shown in Figures 25 and 26, the engagement structure between the sliding part 64 and the fixed part 65 is such that the Y-shaped engagement part 644 of the sliding part 64 is inserted into the space above the first engagement part 6511 (wall portion) of the sliding fixed part 65, and the sliding part 64 is moved downward to attach the sliding part 64 to the fixed part 65. Therefore, the Y-shaped engagement part 644 of the sliding part 64 catches on the first engagement part 6511 (wall portion) of the sliding fixed part 65, preventing it from coming loose in the vertical direction. Furthermore, by moving the sliding part 64 downward, the second engagement part 645 on the sliding part side of the sliding part 64 fits into and engages with the second engagement part 6512 of the sliding fixed part 651 of the fixed part 65, preventing it from coming loose in the horizontal direction (indoor / outdoor direction). As a result, the sliding part 64 and the fixing part 65 are fixed together by a simple method of engagement, preventing them from moving along the direction of movement of the sliding part 64. Therefore, even if the sliding part 64 is moved, it is less likely to come loose, improving operability.

[0082] The frame-side fixing portion 652 is formed in a substantially L-shape and extends upward (outward) from the slide-side fixing portion 651. The frame-side fixing portion 652 has an inner portion 652a that extends inward from the slide-side fixing portion 651 towards the interior side of the inner meeting frame 44, and an outer extending portion 652b that extends upward (outward) from the inner portion 652a. As shown in Figures 20A and 21, the upper end portion 6522 of the frame-side fixing portion 652 is fixed to the inner meeting frame 44 by a screw 65a. A rib 6521 is formed on the upper outer extending portion 652b of the frame-side fixing portion 652. As shown in Figure 21, the rib 6521 is formed projecting outward from the interior side X2 surface of the upper part of the frame-side fixing portion 652 and extends in the vertical direction.

[0083] When attaching the operating unit 63 to the inner meeting frame 44 of the inner sliding door 4, as shown in Figure 30, the operating unit 63 has a configuration in which a sliding movement part 64 is fixed to a fixing part 65. With the operating unit 63 tilted, the tip of the outer extension 652b of the approximately L-shaped frame-side fixing part 652 is inserted into the opening 44a of the inner meeting frame 44. Then, the operating unit 63 is gradually moved from its tilted position to an upright position and inserted into the interior of the opening 44a of the inner meeting frame 44. After inserting the operating section 63 into the opening 44a of the inner meeting frame 44, the multiple claw-shaped engaging sections 6513 are engaged with both lateral ends of the opening 44a (see Figure 17) of the inner meeting frame 43, and the hooking engaging groove 6514 is engaged with the lower end of the opening 44a of the inner meeting frame 43, and the outer end X1 on the longitudinal side of the shaft 643 of the sliding section 64 of the operating section 63 is positioned indoors The operating part 63 is inserted into the opening 6221 of the indoor lock support part 622 of the indoor lock body part 622, and the lower support projection 653 of the fixing part 65 of the operating part 63 is locked to the opening locking part 6222 of the indoor lock support part 622 of the indoor lock body part 622, thereby positioning the operating part 63 inside the inner meeting frame 44. Then, the upper end portion 6522 of the frame-side fixing part 652 is fixed to the indoor lock body part 62 with a screw 65a.

[0084] This allows the operating unit 63 to be attached to the inner meeting stile 44 of the inner sliding door 4. By forming the frame-side fixing portion 652 of the fixing portion 65 in a roughly L-shape, it is easier to insert it into the opening 44a of the inner meeting stile 44, and the amount of movement of the frame-side fixing portion 652 of the fixing portion 65 can be reduced during installation, thereby improving workability.

[0085] As shown in Figures 20A and 20B, the indoor locking hook portion 623 is positioned at the bottom of the indoor lock body portion 62. As shown in Figure 20A, when the locking device 6 is unlocked because the sliding portion 64 is in the unlocked position, the indoor locking hook portion 623 is retracted toward the inner meeting stile 44 and does not protrude toward the outer meeting stile 34, thus unlocking without catching on the outer meeting stile 34. Also, as shown in Figure 20B, when the locking device 6 is locked because the sliding portion 64 is in the locked position, the indoor locking hook portion 623 protrudes from the inner meeting stile 44 toward the outer meeting stile 34, catching on the outer meeting stile 34 and locking.

[0086] As shown in Figures 18 to 20A, the cylinder lock 66 is installed on the outer meeting frame 34 of the outer sash 3. The cylinder lock 66 has a cylinder lock body 67 installed inside the outer meeting frame 34 of the outer sash 3, and a cylinder part 68 (keyhole part) in which a keyhole 681 is formed. When the cylinder lock 66 is installed on the outer meeting frame 34 of the outer sash 3, the surface 340 of the outer meeting frame 34 of the outer sash 3 extends to the periphery of the cylinder part 68. When the cylinder lock 66 is installed on the outer meeting frame 34 of the outer sash 3, the part of the cylinder part 68 other than the tip is located inside the outer meeting frame 34 of the outer sash 3. The periphery of the cylinder part 68 and the surface 340 of the outer meeting frame 34 of the outer sash 3 are continuous. As shown in Figure 19, the surface 340 (outside surface) of the outer meeting frame 34 of the outer sash 3 and the surface 68a (outside surface) of the outer meeting frame 68 of the cylinder part 68 are formed on substantially the same plane.

[0087] As shown in Figures 2 and 19, a vertical frame-side recess 3401 (first recess) is formed on the outdoor side surface 340 of the outer meeting frame 34, which is a vertical frame, recessing inward in the depth direction. The vertical frame-side recess 3401 extends in the vertical direction. As shown in Figures 18 and 19, the vertical frame-side recess 3401 has a planar bottom surface portion 3401a that has width in the left-right direction and extends in the vertical direction, and a pair of inclined stepped portions 3401b formed at both ends of the bottom surface portion 3401a in the left-right direction (width direction) and inclined from the indoor side X2 to the outdoor side X1 as it moves outward in the left-right direction. The cylinder portion 68 is positioned in the vertical frame-side recess 3401.

[0088] As shown in Figures 2 and 31, a horizontal frame side recess 3201 (second recess) is formed on the outdoor side surface 320 of the lower frame 32, which is a horizontal frame connected to the outer meeting frame 34, which is a vertical frame, and recesses inward in the depth direction. The horizontal frame side recess 3201 extends in the left-right direction. The horizontal frame side recess 3201 has a planar bottom surface portion 3201a that has width in the vertical direction and extends in the left-right direction, and an inclined step portion 3201b formed at the upper end of the bottom surface portion 3201a that slopes from the indoor side X2 towards the outdoor side X1 as it moves upward in the vertical direction.

[0089] The vertical frame-side recess 3401 formed on the surface 340 of the outer meeting stile 34 and the horizontal frame-side recess 3201 formed on the surface 320 of the lower frame 32 are formed with the same depth. In this embodiment, as shown in Figure 19, the depth of the vertical frame-side recess 3401 is the distance between the surface 340 of the outdoor side X1 of the outer meeting stile 34 and the bottom surface 3401a of the vertical frame-side recess 3401, which is depth D. As shown in Figure 31, the depth of the horizontal frame-side recess 3201 is the distance between the surface 320 of the outdoor side X1 of the lower frame 32 and the bottom surface 3201a of the horizontal frame-side recess 3201, which is the same depth as the vertical frame-side recess 3401, which is depth D.

[0090] As shown in Figures 20A and 20B, the cylinder lock body 67 has a cylinder-side support portion 671 and a cylinder-side hook portion 672. The cylinder-side hook portion 672 has a first hook portion 672a and a second hook portion 672b.

[0091] The cylinder-side support portion 671 is positioned on the indoor side X2 of the cylinder portion 68 inside the inner meeting frame 44 of the inner sliding door 4. The cylinder-side support portion 671 supports the indoor side X2 portion of the cylinder portion 68.

[0092] When a key (not shown) is inserted into the keyhole 681 of the cylinder 68 and rotated, the first hook portion 672a and the second hook portion 672b of the cylinder side hook portion 672 are moved to the unlocked position or the locked position, thereby moving the indoor lock hook portion 623 of the indoor lock body portion 62 of the indoor lock portion 61, and thereby locking and unlocking the locking device 6.

[0093] Next, we will describe the details of the first end component 81 (end component), the second end component 82 (end component), the closing component 83, and the airtight component 84, which are provided on the upper surface of the lower frame 22.

[0094] As shown in Figures 5 and 6, the lower frame 22 includes a lower section 251 (stepped section), a middle section 252 (stepped section), and an upper section 253 (stepped section) whose upper surface is positioned lower as it moves from the indoor side X2 to the outdoor side X1. In this embodiment, the lower frame 22 is configured to be positioned lower as it moves from the indoor side X2 to the outdoor side X1 by providing stepped sections, but it is not limited to this configuration, and the lower frame 22 may also be configured to be positioned lower as it moves from the indoor side X2 to the outdoor side X1 by providing inclined sections.

[0095] The first end component 81 and the second end component 82 are formed in the shape of pieces with a predetermined width in the left-right direction and are arranged on the upper surface of the lower frame 22. The first end component 81 and the second end component 82 are provided on the outside of the left-right ends of the outdoor rail 220a and the indoor rail 220b provided on the lower frame 22.

[0096] As shown in Figures 1 and 6, the first end component 81 is positioned on the upper surface of one end of the lower frame 22 in the left-right direction, and outside the one end of the stainless steel rail member 26 in the left-right direction. When the outer sash 3 is in the closed position, the first end component 81 is positioned on the upper surface of the lower frame 22, which is located below the end of the outer sash 3 on the door-edge side, on the vertical frame 33 side.

[0097] As shown in Figures 6 and 32, the first end component 81 has an end component body 811 and a detachable cap 812. The end component body 811 has a bottom plate portion 8111, a stopper portion 8112, and a pair of cap mounting portions 8113. The end component body 811 is fixed to one end of the middle section 252 of the lower frame body 25 in the left-right direction by a screw 81a.

[0098] The bottom plate portion 8111 is formed in a plate shape with thickness in the vertical direction and is positioned on the upper surface of one end in the left-right direction of the middle section 252 of the lower frame body 25. The bottom plate portion 8111 is positioned outside of one end in the left-right direction of the central stainless steel member 262. The upper surface of the bottom plate portion 8111 is positioned on approximately the same plane as, or slightly below, the upper surface of the lower plate portion 2621 of the central stainless steel member 262.

[0099] The stopper portion 8112 is positioned on the indoor side X2 of the bottom plate portion 8111. The stopper portion 8112 is formed in the shape of a box with a rectangular parallelepiped outer shape. The stopper portion 8112 is positioned on the outside of one end in the left-right direction of the indoor rail 220b that guides the lower end of the inner sash 4. The stopper portion 8112 is positioned across the middle portion 252 and the upper portion 253 of the lower frame body 25. The stopper portion 8112 has the function of a lower frame stopper that restricts the movement of the inner sash 4 beyond the left-right ends of the lower frame 22. Because the first end component 81 has the stopper portion 8112, the number of parts can be reduced, and manufacturing costs can be reduced. The first end component 81 having the stopper portion 8112 is provided with a removable cap 812.

[0100] The pair of cap mounting sections 8113 are positioned at the outdoor side X1 end of the bottom plate section 8111, and are spaced apart in the left-right direction on the extension line of one end of the outdoor rail 220a of the lower frame 22. A removable cap 812 is detachably attached between the pair of cap mounting sections 8113.

[0101] If you want to sweep dirt, dust, etc. from the upper surface of the lower plate portion 2621 of the central stainless steel member 262 between the outdoor rail 220a and the indoor rail 220b at one end of the lower frame 22 in the left-right direction to the outdoor side X1, you can remove the detachable cap 812 from the pair of cap mounting portions 8113 to sweep the dirt, dust, etc. on the upper surface of the lower plate portion 2621 to the outdoor side X1. Details of the mounting structure of the detachable cap 812 will be described later.

[0102] As shown in Figures 2 and 6, the second end component 82 is positioned on the upper surface of the other end of the lower frame 22 in the left-right direction, and outside the other end of the stainless steel rail member 26 in the left-right direction. When the inner sash 4 is in the closed position, the second end component 82 is positioned on the upper surface of the lower frame 22, which is located below the end of the vertical frame 43 on the door-edge side of the inner sash 4.

[0103] As shown in Figure 33, the second end component 82 has an end component body 821 and a detachable cap 822. The end component body 821 has a bottom plate portion 8211, a pair of cap mounting portions 8212, and an upper sweep portion 8213 in which a sweep guide groove 8214 is formed. The end component body 821 is fixed to the other end portion in the left-right direction of the middle portion 252 of the lower frame body 25 by screws 82a.

[0104] The bottom plate portion 8211 is formed in a plate shape with thickness in the vertical direction and is positioned on the upper surface of the other end in the left-right direction of the middle section 252 of the lower frame body 25. The bottom plate portion 8211 is positioned outward from the other end in the left-right direction of the central stainless steel member 262. The upper surface of the bottom plate portion 8211 is positioned on approximately the same plane as, or slightly below, the upper surface of the lower plate portion 2621 of the central stainless steel member 262.

[0105] The pair of cap mounting sections 8212 are positioned at the indoor side X2 end of the bottom plate section 8211, and are spaced apart in the left-right direction on the extension line of one end of the indoor rail 220b of the lower frame 22. A removable cap 822 is detachably attached between the pair of cap mounting sections 8212.

[0106] If you want to sweep out debris and dust from the upper surface of the upper part 253 of the lower frame body 25 between the indoor rail 220b and the indoor end wall 220d to the outdoor side X1 at the other end of the lower frame 22 in the left-right direction, you can remove the detachable cap 822 from the pair of cap mounting parts 8212 to sweep out debris and dust from the upper surface of the upper part 253 of the lower frame body 25 to the outdoor side X1.

[0107] The upper sweep section 8213 is formed as a thin plate on the indoor side X2 of the bottom plate section 8211, above the bottom plate section 8211, and is positioned one step higher than the bottom plate section 8211. A sweep guide groove 8214 is formed on the outdoor side X1 of the upper sweep section 8213. In plan view, the sweep guide groove 8214 is formed as an arc approximately 1 / 4 of the entire circumference of a circle, recessed on the left and right outer sides and the indoor side X2, while being open on the left and right inner sides and the outdoor side X1. When dust and debris on the upper surface of the lower plate section 2621 of the central stainless steel member 262 of the lower frame 22 are swept toward one end in the left and right direction, they can be moved along the arc portion of the sweep guide groove 8214 to the outdoor side X1, thus making it easy to sweep dust and debris to the outdoor side X1.

[0108] The second end component 82 is made of resin material and, as shown in the upper diagram of Figure 34, is shaped to curve downward as it moves outward in the left-right direction from the fixing hole 8213a for fixing the fixing member. It is biased downward so that the end on the outdoor side X1 is lower than the end on the indoor side X2 in the depth direction by, for example, a distance T as shown in the upper diagram of Figure 34. As a result, when the second end component 82 is attached to the lower frame 22, the second end component 82 is attached to the lower frame 22 with the end on the outdoor side X1 in the depth direction biased downward, as shown in the lower diagram of Figure 34.

[0109] The detachable caps 812 and 822 will now be described. As shown in Figure 32, the detachable caps 812 and 822 are formed in a plate shape with thickness in the depth direction, width in the vertical direction, and extension in the left-right direction. The detachable cap 812 is detachably attached to the first end part 81 on the extension of the outdoor rail 220a at the position where the outdoor rail 220a is positioned in the depth direction. The detachable cap 822 is detachably attached to the second end part 82 on the extension of the indoor rail 220b at the position where the indoor rail 220b is positioned in the depth direction.

[0110] The detachable caps 812 and 822 have similar shapes and are formed to be symmetrical on both the left and right sides, and on both the front and back sides, when viewed from a predetermined direction. Therefore, the detachable caps 812 and 822 can be attached to the pair of cap mounting portions 8113 of the first end component 81 and the pair of cap mounting portions 8212 of the second end component 82 without worrying about the left / right or front / back orientation of the detachable caps 812 and 822. Furthermore, the detachable cap 812 can be attached to the pair of cap mounting portions 8212 of the second end component 82, and the detachable cap 822 can be attached to the pair of cap mounting portions 8113 of the first end component 81.

[0111] The structure for attaching the detachable cap 812 to the pair of cap mounting portions 8113 of the first end component 81 and the structure for attaching the detachable cap 822 to the pair of cap mounting portions 8212 of the second end component 82 are similar. In this embodiment, the structure for attaching the detachable cap 822 to the pair of cap mounting portions 8212 of the second end component 82 will be described.

[0112] As shown in Figure 33, the pair of cap mounting portions 8212 of the second end component 82 each have a rod-shaped portion 8212a extending in the vertical direction and an engaging projection 8212b that protrudes inward from the middle of the rod-shaped portion 8212a in the vertical direction.

[0113] As described above, the detachable cap 822 is formed in a plate shape with thickness in the depth direction, has width in the vertical direction, and extends in the left-right direction. The detachable cap 822 has a pair of cap-side engaging portions 8221 formed at both ends in the left-right direction. Each of the pair of cap-side engaging portions 8221 has a vertical groove portion 8221a extending in the vertical direction, and an engaging projection portion 8221b that protrudes outward from the vertical groove portion 8221a from the middle of the vertical groove portion 8221a.

[0114] When attaching the detachable cap 822 to the pair of cap mounting portions 8212 of the second end component 82, the detachable cap 822 is moved toward the pair of cap mounting portions 8212 of the second end component 82, and the pair of vertical grooves 8221a of the detachable cap 822 are moved along the pair of rod-shaped portions 8212a of the pair of cap mounting portions 8212, so that the engaging projections 8212b of the cap mounting portion 8212 fit into the pair of engaging protrusions 8221b of the detachable cap 822 and engage.

[0115] The blocking component 83 is positioned on the upper surface of the outdoor-side portion X1 of the outdoor-side stainless steel member 261 of the stainless steel member 26 of the lower frame 22, on the left-right central side. As shown in Figure 2, the blocking component 83 is provided in the portion where the meeting stile 34 (meeting stile) of the outer sash 3 and the lower frame 22 overlap.

[0116] As shown in Figures 5, 6, and 35, the blocking component 83 is positioned between the screen door rail 220c and the outdoor rail 220a (sliding door rail) on the upper surface of the lower frame 22 of the frame 2. The blocking component 83 is formed in a flat plate shape. In this embodiment, the blocking component 83 is positioned between the screen door rail 220c and the outdoor rail 220a (sliding door rail) on the upper surface of the lower frame 22 of the frame 2, thereby blocking the space between the screen door rail 220c and the outdoor rail 220a (sliding door rail) on the upper surface of the lower frame 22 of the frame 2, thus preventing insects from entering. Note that "blocking" when the blocking component 83 is blocking means that it may be completely closed and sealed, or it may be closed with a small gap.

[0117] The blocking component 83 is formed in the shape of a plate having thickness in the vertical direction, width in the depth direction, and a piece shape extending a predetermined length in the left-right direction. The blocking component 83 is formed in a stepped shape in the depth direction. As shown in Figures 35 and 36, the blocking component 83 has an indoor plate portion 831 arranged on the indoor side X2, an outdoor plate portion 832 arranged on the outdoor side X1 of the indoor plate portion 831, a recess 834, a fixing hole 834a, a downward projection 835, and a pair of thin-walled space portions 836.

[0118] As shown in Figure 5, the indoor panel portion 831 and the outdoor panel portion 832 are connected with their bottom surfaces located at the same position, and the thickness H2 of the indoor panel portion 831 is greater than the thickness H1 of the outdoor panel portion 832. As shown in Figure 35, a step portion 833 is formed between the indoor panel portion 831 and the outdoor panel portion 832. In this embodiment, for example, the thickness H1 of the outdoor panel portion 832 is 1.4 mm, and the thickness H2 of the indoor panel portion 831 is 3.0 mm.

[0119] As shown in Figure 5, a gap S1 is formed between the lower end of the bottom frame 32 of the outer sash 3 and the upper surface of the indoor side panel 831 of the closing component 83. A gap S2 is formed between the lower end of the bottom frame 52 of the screen door 5 and the upper surface of the outdoor side panel 832 of the closing component 83. The gaps S1 and S2 are, for example, 2.5 mm. There is a JIS standard that states that insect-proof performance can be guaranteed if the size of the gap is 2.5 mm or less, and the design is based on this JIS standard.

[0120] As shown in Figure 35, the recess 834 is formed in the center of the closing part 83 in the left-right direction, straddling the indoor side plate portion 831 and the outdoor side plate portion 832. The recess 834 is a step formed by a cylindrical recess. A fixing hole 834a for fixing a fixing member is formed in the center of the recess 834, penetrating in the vertical direction. Thus, a step of recess 834 is formed around the fixing hole 834a, recessing downward from the upper surface of the closing part 83. When the closing part 83 is fixed to the lower frame 22 with the fixing member 83a, the head of the fixing member 83a is placed on the upper surface of the recess 834 when the fixing member 83a is passed through the fixing hole 834a. As a result, the head of the fixing member 83a is hidden in the recess 834, improving the aesthetic appearance. The fixing member 83a is a fastening member that fastens and fixes, and an example of a fastening member is a screw.

[0121] As shown in Figure 36, the downward projection 835 is formed in a cylindrical shape that protrudes downward from the lower surface of the closing part 83 at the lower surface of the portion where the recess 834 of the closing part 83 is formed. As shown in Figure 36, the downward projection 835 is positioned and engages with a circular opening 2611a formed near the center in the left-right direction of the lower plate portion 2611 of the outdoor stainless steel member 261. Before the closing part 83 is installed, the upper surface of the lower step portion 251 is exposed at the circular opening 2611a of the lower plate portion 2611 of the outdoor stainless steel member 261, and a screw hole 251a is formed in the center of the exposed portion of the lower step portion 251.

[0122] By positioning the downward projection 835 in the left-right circular opening 2611a of the lower plate portion 2611 of the outdoor stainless steel member 261, the position of the recess 834 can be positioned downward. Therefore, when the head of the fixing member 83a is positioned in the recess 834, as shown in Figure 5, the head of the fixing member 83a can be positioned at approximately the height of the outdoor plate portion 832. This improves the aesthetic appearance.

[0123] The closure part 83 is made of resin material and, as shown in the upper diagram of Figure 37, is formed in a shape that curves downward as it moves outward from the fixing hole 834a for fixing the fixing member in the left-right direction. Both ends of the closure part 83 in the left-right direction are formed in a shape that curves downward as it moves outward from the fixing hole 834a for fixing the fixing member in the left-right direction before the closure part 83 is attached to the lower frame 22, and are biased downward as they move outward from the fixing hole 834a for fixing the fixing member in the left-right direction. In this state, the closure part 83 is attached to the lower frame 22 and the fixing member 83a is passed through the fixing hole 834a of the closure part 83 and the screw hole 251a of the lower section 251 and fixed by the fixing member 83a. As a result, when the closure part 83 is attached to the lower frame 22, as shown in the lower diagram of Figure 37, both ends of the closure part 83 in the left-right direction are biased downward, and the closure part 83 is attached to the lower frame 22.

[0124] As shown in Figure 35, the airtight component 84 is positioned on the upper surface of the outdoor-facing portion X1 on the left-right side of the central stainless steel member 262 of the stainless steel member 26 of the lower frame 22. The airtight component 84 is fixed to the central stainless steel member 262 of the stainless steel member 26 of the lower frame 22 by screws 84a. The airtight component 84 is formed in a plate shape that extends in the depth direction and has a bottom plate 841 that has width in the left-right direction and extends in the depth direction, and a plurality of fin portions 842 that protrude upward from both ends of the bottom plate 841 in the left-right direction (width direction) and extend in the depth direction.

[0125] The building fixture 1 of the first embodiment described above can achieve the following effects.

[0126] The locking device 6 of this embodiment includes an indoor lock body 62 provided on the inner meeting stile 44 for locking and unlocking the outer sash 3 and the inner sash 4, and an operating unit 63 provided on the inner meeting stile 44 for operating the locking and unlocking of the indoor lock body 62. The operating unit 63 has a sliding moving part 64 that extends substantially flat on the surface 440 of the inner meeting stile 44 and is movable along the surface 440. The indoor lock body 62 locks and unlocks the outer sash 3 and the inner sash 4 in conjunction with the movement of the sliding moving part 64. Therefore, instead of pinching a knob with fingers as in the conventional technology, the locking and unlocking can be performed by moving the sliding moving part 64, which extends substantially flat on the surface 440 of the inner meeting stile 44, with a hand or the like, resulting in good operability. Furthermore, since the sliding portion 64 extends in a nearly flat manner, it gives a sense of unity that blends well with the surface 440 of the inner meeting frame 44, resulting in a good aesthetic appearance.

[0127] Furthermore, in this embodiment, the sliding part 64 has a shaft portion 643 that extends in the depth direction and is connected to the indoor side lock body portion 62, and a flat plate-shaped operating surface portion 641 that is provided on the longitudinal end side of the shaft portion 643 and extends onto the surface 440 of the inner meeting frame 44. By having an operating surface portion 641 and a shaft portion 643, the number of parts can be reduced. This reduces manufacturing costs.

[0128] Furthermore, in this embodiment, the operating surface portion 641 has curved sides (surface-side inclined curved side portion 6411a and base-side inclined curved side portion 6413a). As a result, the curved shape of the sides of the operating surface portion 641 makes it easier to grip with fingers and improves the feel of the fingers, thereby improving operability.

[0129] Furthermore, in this embodiment, the operating surface 641 has a display window 6414 on its surface that displays the locked / unlocked status of the indoor lock body 62. By providing the display window 6414, the locked and unlocked status can be easily understood visually.

[0130] Furthermore, in this embodiment, the operating unit 63 has a fixing unit 65 that fixes the sliding unit 64 to the inner meeting frame 44, and the fixing unit 65 has a rectangular parallelepiped-shaped sliding-side fixing unit 651 that is fixed to the sliding unit 64, and a frame-side fixing unit 652 that is fixed to the inner meeting frame 44 and has an inner portion 652a that extends from the sliding-side fixing unit 651 toward the inside of the inner meeting frame 44 and an outer extending portion 652b that extends outward from the inner portion 652a.

[0131] The size of the sliding part 64 should be kept as small as possible, but to do so, the opening size of the sliding-side fixing part 651 and the inner meeting frame 44 that are fixed to it must also be reduced. If these are reduced, the size may not correspond to the size of a general-purpose lock body. In such cases, by fixing the sliding-side fixing part 652, which extends outward toward the inside of the inner meeting frame 44 rather than the sliding-side fixing part 651, it is possible to make it compatible with a general-purpose lock body. By forming the frame-side fixing part 652 in a roughly L-shape, it is easier to insert it into the opening 44a of the inner meeting frame 44, improving ease of installation.

[0132] Furthermore, in this embodiment, a rib 6521 is formed on the frame-side fixing portion 652. This improves the strength of the frame-side fixing portion 652.

[0133] Furthermore, in this embodiment, the slide-side fixing portion 651 is formed with a plurality of claw-shaped engaging portions 6513 that engage with the inner meeting frame 44. As a result, it is difficult for the operating portion 63 to come off even if an operating force is applied.

[0134] Furthermore, in this embodiment, the sliding part 64 extends onto the surface 440 (visible surface) of the inner meeting stile 44 and is movable along the surface 440 (visible surface) of the inner meeting stile 44. As a result, the surface 440 (visible surface) of the inner meeting stile 44 is easily visible when viewed from the front of the interior side X2 of the door 1, thereby improving the aesthetic appearance.

[0135] Furthermore, in the prior art, removing the cover makes it easy to access the cylinder lock, which presents security challenges. In contrast, in this embodiment, the locking device 6 is provided on the outer meeting frame 34 of the outer sash 3 and is a locking device 6 for locking and unlocking the outer sash 3 and the inner sash 4. The locking device 6 includes a cylinder lock 66 provided on the outer meeting frame 34. The cylinder lock 66 has a cylinder lock body 67 provided inside the outer meeting frame 34 and a keyhole 68 with a keyhole 681 formed therein. When the cylinder lock 66 is provided on the outer meeting frame 34, the part of the cylinder 68 other than the tip is located inside the outer meeting frame 34 of the outer sash 3. This makes it difficult to access the cylinder lock body 67, thereby improving security.

[0136] Furthermore, in this embodiment, the periphery of the cylinder portion 68 and the surface 340 of the outer meeting frame 34 of the outer sliding door 3 are continuous. As a result, in this disclosure, there is no cover around the cylinder portion 68, and since the periphery of the cylinder portion 68 and the surface 340 of the outer meeting frame 34 of the outer sliding door 3 are continuous, it is difficult to access the cylinder lock body 67, thereby improving security. Moreover, it is possible to improve the sense of unity by blending in with the surface 340 of the outer meeting frame 34, resulting in good design aesthetics.

[0137] Furthermore, in this embodiment, the surface 340 of the outer meeting frame 34 of the outer sliding door 3 and the surface 68a of the cylinder portion 68 are formed on substantially the same plane. Therefore, since the surface 68a of the cylinder portion 68 does not protrude or recess from the surface 340 of the outer meeting frame 34 of the outer sliding door 3, the sense of unity between the surface 68a of the cylinder portion 68 and the surface 340 of the outer meeting frame 34 can be further improved, thereby improving the aesthetic appearance.

[0138] Furthermore, in this embodiment, in the outer shoji screen 3, a vertical frame-side recess 3401 (first recess) is formed on the surface 340 of the outer meeting stile 34, which is recessed inward in the depth direction, and the cylinder portion 68 is positioned in the vertical frame-side recess 3401. As a result, when a member such as a screen door 5 is installed on the outside of the outer meeting stile 34, the member such as the screen door 5 is less likely to interfere with the cylinder portion 68.

[0139] Furthermore, in this embodiment, a horizontal recess 3201 (second recess) is formed on the surface 320 of the lower frame 32, which is a horizontal frame connected to the outer meeting frame 34, which is a vertical frame, and is recessed inward in the depth direction. The vertical recess 3401 formed on the surface 340 of the outer meeting frame 34 and the horizontal recess 3201 formed on the surface 320 of the lower frame 32 are formed with the same depth D. As a result, the surface 320 of the lower frame 32, which is a horizontal frame to which the cylinder lock 66 is not attached, also has a recess shape with the same depth as the vertical recess 3401 formed on the surface 340 of the outer meeting frame 34, thus creating a sense of unity throughout the frame body 30 and improving its design.

[0140] Furthermore, in this embodiment, the door frame 1 has metal profiles 331, 351 and resin profiles 332, 352 arranged side by side in the interior-exterior direction and engaging with each other, with end caps 7 provided at the left and right ends of the resin profile 352 of the middle rail 35, the left and right ends of the metal profile 351 of the middle rail 35 abutting against the metal profile 331 of the middle rail 35 and fixed with a fixing member 33a, and the left and right ends of the resin profile 352 of the middle rail 35 fixed to the resin profile 332 of the vertical frame 33 on the door frame side via the end caps 7.

[0141] As a result, when fixing the vertical frame 33 on the door edge side and the intermediate rail 35, the fixing member 33a securely fixes the members by fixing the metal profile 331 of the vertical frame 33 on the door edge side and the metal profile 351 of the intermediate rail 35 to each other without the need for any intermediary parts. At the same time, the left and right ends of the resin profile 352 of the intermediate rail 35 are fixed via the end caps 7. This eliminates the need to cut out the vertical frame 33 on the door edge side to fix the resin profile 352 of the intermediate rail 35 to the resin profile 332 of the vertical frame 33 on the door edge side, thereby improving the ease of installation of the vertical frame 33 on the door edge side and the intermediate rail 35.

[0142] Furthermore, in this embodiment, the metal profile 351 of the intermediate rail 35 is fixed in a state where it is swallowed by the metal profile 331 of the vertical frame 33 on the door edge side, and the resin profile 352 of the intermediate rail 35 is engaged and fixed by an end cap 7 that abuts against the inner circumference end face 332a of the resin profile 332 of the vertical frame 33 on the door edge side. This eliminates the need to cut out the vertical frame 33 on the door edge side in order to fix the resin profile 352 of the intermediate rail 35 to the resin profile 332 of the vertical frame 33 on the door edge side, thereby improving ease of installation.

[0143] Furthermore, in this embodiment, the end cap 7 has an insertion portion 71 that is inserted into the resin profile 352 of the middle crossbar 35, and a projection 74 that engages with the metal profile 351 of the middle crossbar 35. The end cap 7 can be fixed by inserting it into the resin profile 352 of the middle crossbar 35 and engaging the metal profile 351 of the middle crossbar 35 with the projection 74.

[0144] Furthermore, in this embodiment, the end cap 7 has a cover portion 72 that abuts against the inner circumferential end surface 332a of the resin profile 332 of the vertical frame 33 on the door edge side, and a claw portion 75 that engages with the resin profile 332 of the vertical frame 33 on the door edge side, located on the outer circumferential side of the cover portion 72. As a result, the cover portion 72 of the end cap 7 can be abutted against the inner circumferential end surface 332a of the resin profile 332 of the vertical frame 33 on the door edge side, and the claw portion 75 can be engaged with the resin profile 332 of the vertical frame 33 on the door edge side, located on the outer circumferential side of the cover portion 72, thus allowing for simple fixing.

[0145] Furthermore, in this embodiment, the metal profile 331 of the vertical frame 33 on the door edge side and the metal profile 351 of the middle rail 35 are made of aluminum, while the resin profile 332 of the vertical frame 33 on the door edge side and the resin profile 352 of the middle rail 35 are made of resin. This improves the thermal insulation performance.

[0146] Furthermore, in this embodiment, the lower frame 22 is provided with stepped portions 251, 252, and 253 on its upper surface that are positioned lower as they move from the indoor side X2 towards the outdoor side X1. The lower frame 22 is provided with end parts 81 and 82 located on the upper surface and at the left and right ends of the outdoor side rail 220a and indoor side rail 220b provided on the lower frame 22. Detachable caps 812 and 822 are attached to the end parts 81 and 82 at the positions where the outdoor side rail 220a and indoor side rail 220b are positioned in the depth direction.

[0147] As a result, during cleaning, the detachable caps 812 and 822 can be removed from the first end part 81 and the second end part 82, allowing dirt and dust to be swept out from the left and right ends of the outdoor rail 220a and the indoor rail 220b. At this time, the lower section 251 (stepped section), the middle section 252 (stepped section), and the upper section 253 (stepped section) formed on the upper surface of the lower frame 22 make it easier to sweep out. During normal use, the detachable caps 812 and 822 are attached to the outdoor rail 220a and the indoor rail 220b, functioning as rail extensions while improving airtightness between the rails of the lower frame 22 (outdoor rail 220a and indoor rail 220b) and the vertical frames 23 and 24, and making it easier to discharge dirt when cleaning.

[0148] Furthermore, in this embodiment, the detachable caps 812 and 822 are formed to be symmetrical both left-right and front-back when viewed from a predetermined direction. This allows the detachable caps 812 and 822 to be easily attached to the first end component 81 and the second end component 82 without having to worry about the mounting direction.

[0149] Furthermore, in this embodiment, the second end component 82 has a sweeping guide groove 8214. Along the sweeping guide groove 8214, dirt and dust can be swept out from the left and right ends of the outdoor rail 220a and the indoor rail 220b for cleaning. This makes cleaning easy.

[0150] Furthermore, in this embodiment, the sweeping guide groove 8214 is formed in an arc shape when viewed from above. Along the arc-shaped portion of the sweeping guide groove 8214, dirt and dust can be swept out from the ends of the outdoor rail 220a and the indoor rail 220b for cleaning. This makes cleaning easy.

[0151] Furthermore, in this embodiment, the two or more sashes 3, 4 include an inner sash 4 positioned on the indoor side X2 and an outer sash 3 positioned on the outdoor side X1. The first end component 81 has the function of a lower frame stopper that restricts the movement of the inner sash 4 toward the left-right end of the lower frame 22, and the detachable cap 812 is provided on the first end component 81 that has the function of a lower frame stopper. Therefore, the first end component 81 can be equipped with both the function of a lower frame stopper and the function of a detachable cap 812, thus reducing the number of parts and lowering manufacturing costs.

[0152] Furthermore, this embodiment also includes a sealing component 83 provided at the point where the meeting stiles 34, 44 of the shoji screens 3, 4 and the lower frame 22 overlap. The sealing component 83 can prevent insects from entering.

[0153] Furthermore, in this embodiment, the closing component 83 is positioned between the screen door rail 220c and the exterior rail 220a (sliding door rail) on the lower frame 22 of the frame body 2, and is formed in a flat plate shape. As a result, because the closing component 83 is flat and thin, it is less likely to interfere with the opening and closing of the sliding doors 3 and 4. This makes it possible to have a closing component 83 that does not interfere with the opening and closing of the sliding doors 3 and 4 while ensuring insect-proof performance.

[0154] Furthermore, in this embodiment, the closing component 83 has a fixing hole 834a for fixing the fixing member, and is formed in a curved shape that becomes more curved the further it is from the fixing hole 834a. This makes it possible to suppress the lifting of the closing component 83 when it is fixed with screws.

[0155] Furthermore, in this embodiment, a recess 834 is formed around the fixing hole 834a, recessing downward from the upper surface of the closing component 83. As a result, the head of the fixing member 83a is hidden in the recess 834, thereby improving the aesthetic appearance.

[0156] Next, the second embodiment of the joinery 1A will be described. The second embodiment of the joinery 1A differs from the first embodiment of the joinery 1 mainly in that the outer sash 3A and the inner sash 4A do not have a middle rail (horizontal frame). The second embodiment of the joinery 1A has the same configuration as the first embodiment in respect to the configuration related to the middle rail (horizontal frame), and can achieve the same effects as the first embodiment.

[0157] While a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment described above and can be modified as appropriate.
