Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, fittings with large openings have been known. In fittings with large openings, the rigidity of the vertical frames of the shoji screens is increased by, for example, widening the width of the vertical frames, thereby ensuring wind pressure resistance so that the vertical frames do not bend in the wind. When the vertical frames are widened, when the shoji screen is closed and viewed from inside the room, the line of the opening in the frame body and the line of the glass fitted in the vertical frames of the shoji screen do not align, and the vertical frames of the shoji screen protrude to the left and right inward of the opening in the frame body, making the vertical frames of the shoji screen visible from inside the room (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-169497 Summary of the Invention [Problem to be solved by the invention]

[0004] When a shoji screen with a wider vertical frame is closed and viewed from inside the room, the line of the opening in the frame and the line of the glass embedded in the vertical frame of the shoji screen do not align, and if the vertical frame of the shoji screen is visible from inside the room, the design may be impaired. On the other hand, for fittings with large openings, it is necessary to ensure the strength of the shoji screen. Therefore, for fittings with large openings, it is necessary to ensure strength while maintaining design.

[0005] The present disclosure aims to provide a fixture that can ensure strength while maintaining design. [Means for solving the problem]

[0006] The present disclosure relates to a fitting comprising a frame body having a vertical frame, a shoji screen arranged within the frame body and having a vertical stile, and a reinforcing member provided on the vertical frame that reinforces the strength of the vertical stile by restricting movement of the vertical stile in the forward direction when the shoji screen is in the closed position, wherein the inner peripheral end of the vertical stile is arranged along the line of an opening on the indoor side of the frame body.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In this specification, the "front view direction" refers to the direction along the indoor / outdoor direction of a fixture. The "front view direction" refers to the direction along the surface direction of the glass (surface material) of the fixture, and is a direction perpendicular to the front view direction. The "front view surface" refers to the surface of the fixture facing the outdoor side and the indoor side, respectively, and the "front view surface" refers to the surface of the fixture extending in the indoor / outdoor direction. In the drawings, the outdoor side of the fixture is referred to as "outdoor side X1," and the indoor side of the fixture is referred to as "indoor side X2." The horizontal direction when the fixture is viewed from the front is referred to as "left and right."

[0009] As shown in FIG. 1, the fitting 1 of the first embodiment is configured by fitting a frame 2 attached to an opening 11 in a building skeleton 100 with two shoji screens: an outer shoji screen 3 (shoji screen) located on the outside X1 of the frame 2 on one side (left side in FIG. 1) of the frame 2 in the left-right direction, and an inner shoji screen 4 located on the inside X2 of the frame 2 on the other side (right side in FIG. 1) of the frame 2 in the left-right direction. The two shoji screens 3, 4 are configured to be slidable in the left-right direction (horizontal direction) within the frame 2. In FIG. 1, a screen door 5 is not shown. Note that either or both of the two shoji screens 3, 4 may be configured as fixed shoji screens, in which they are fixed within the frame 2. Note that the two shoji screens 3, 4 are not limited to sliding windows that can slide within the frame 2, but may be other types of windows such as casement windows.

[0010] The fitting 1 of this embodiment is a fitting placed in an opening 11 of a building skeleton 100. In this embodiment, the opening 11 is formed as a large opening. For example, in this embodiment, the opening 11 being a large opening is assumed to be an opening with a height H of 2000 mm or more, as shown in FIG. 1. The width W of the opening is assumed to be an opening with a width W of 2600 mm or more.

[0011] When placing a fixture in the opening 11 with a large opening, it becomes necessary to increase the rigidity of the vertical stiles of the shoji screen by, for example, widening the width of the stiles to ensure wind pressure resistance so that the stiles do not bend in the wind. On the other hand, if the width of the stiles of the shoji screen is widened to increase their rigidity, when the shoji screen is closed and viewed from inside the room, the line of the opening in the frame and the line of the glass embedded in the stiles of the shoji screen will not be aligned, causing the stiles to protrude to the left and right inward of the opening in the frame, making them visible from inside the room and potentially reducing the design quality. The fixture 1 of this embodiment employs a configuration to solve these problems.

[0012] The frame body 2 is placed in the opening 11 of the building skeleton 100. The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape. An opening 200 is formed inside the frame body 2, and shoji screens 3, 4 are placed in the opening 200 inside the frame body 2. This allows the shoji screens 3, 4 to be placed inside the frame body 2 so that they can be opened and closed. The shoji screens 3, 4 are made up of an outer shoji screen 3 placed on the outside X1 of the room, and an inner shoji screen 4 placed on the inside X2 of the room.

[0013] As shown in Figure 1, the outer shoji screen 3, which is placed on the outside X1, is constructed by fitting a surface material 35 made of one or more pieces of glass or the like inside a rectangular frame body made up of an upper frame 31, a lower frame 32, and a pair of left and right vertical frames 33, 34. The inner shoji screen 4, which is placed on the inside X2, is constructed by fitting a surface material 45 made of one or more pieces of glass or the like inside a rectangular frame body made up of an upper frame 41, a lower frame 42, and a pair of left and right vertical frames 43, 44.

[0014] As shown in FIG. 2, 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 surface of the inner periphery of the frame on the indoor side X2 of the upper frame main body 210. Therefore, it has excellent heat insulation and moisture resistance. The upper frame main body 210 is arranged on the outdoor side X1 of the upper frame 21. The resin cover material 215 is attached to the indoor side X2 part of the upper frame main body 210. Above the opening 11, the end part of the upper frame 21 on the indoor side X2 is fixed to the edge member 101 of the building skeleton 100.

[0015] The upper frame body 210 is divided into two parts in the prospective direction: an outdoor frame member 211 (outdoor portion) and an indoor frame member 212 (indoor portion). The outdoor frame member 211 and the indoor frame member 212 are each made of extruded shapes extruded in the longitudinal direction from a metal material such as aluminum. A bridge member 213 is arranged 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 thermally insulating material such as resin, and blocks heat transfer from the outdoor frame member 211 to the indoor frame member 212 in the upper frame 21.

[0016] As shown in Figure 2, the outdoor frame member 211 has a hollow frame section 2111 that is approximately rectangular in cross section and is located at the top, a guide rail 210a for the outer shoji screen 3 that protrudes downward from the part of the underside of the hollow frame section 2111 closer to the outdoor side X1, and a guide rail 210c for the screen door 5 that protrudes downward from the end of the underside of the hollow frame section 2111 closer to the outdoor side X1.

[0017] The indoor frame member 212 has a front-facing extending portion 2121 extending in the front direction on the outside side X1, an outdoor-side upward protruding portion 2122 protruding upward from the outdoor-side X1 end of the front-facing extending portion 2121, an indoor-side upward protruding portion 2123 protruding upward from the indoor-side X2 end of the front-facing extending portion 2121, a downward-sloping extending portion 2124 protruding downward from the indoor-side X2 end of the front-facing extending portion 2121 and then extending at a downward slope as it goes from the outdoor-side X1 to the indoor-side X2, an indoor-side end downward protruding portion 2125 protruding downward from the indoor-side X2 end of the downward-sloping extending portion 2124, and a guide rail 210b for the inner shoji screen 4 protruding downward from the outdoor-side X1 end of the front-facing extending portion 2121.

[0018] A pair of guide rails 210a, 210b provided on the indoor frame member 212 and the outdoor frame member 211 are guide rails for the two outer and inner shoji screens 3 and 4 housed inside the frame body 2. The guide rail 210c provided on the end of the outdoor frame member 211 on the outdoor side X1 is a guide rail for the screen door 5 housed on the most outdoor side X1. The guide rails 210a, 210b, 210c extend over the entire length of the upper frame 21 in the longitudinal direction.

[0019] A pair of guide rails 210a, 210b for the two shoji screens 3, 4 guide the upper parts of the shoji screens 3, 4 (see FIG. 1). Guide rail 210a is provided on the outside side X1, and guide rail 210b is provided on the inside side X2. Guide rail 210c for screen door 5 is provided at the end of the outside side X1 and guides the upper part of screen door 5.

[0020] A resin inter-rail cover 2112 is attached between the pair of guide rails 210a, 210b of the upper frame 21. The inter-rail cover 2112 is disposed across the lower surface of the exterior frame member 211 and the lower surface side of the bridge material 213 so as to substantially shield the space between the guide rails 210a, 210b of the upper frame 21.

[0021] 2, the rail-to-rail cover 2112 has a double structure made up of an upper plate portion 2112a, a lower plate portion 2112b arranged below and substantially parallel to the upper plate portion 2112a, and a plurality of connecting plate portions 2112c connecting the upper plate portion 2112a and the lower plate portion 2112b. The rail-to-rail cover 2112 prevents the outside air temperature transmitted to the upper frame 21 from being transmitted to the inner periphery of the upper frame 21.

[0022] A resin cover material 215 made of resin is attached to the lower part of the end portion on the indoor side X2 of the indoor side frame member 212 of the upper frame body 210. The resin cover material 215 has a cover portion 216 and an angle portion 217.

[0023] As shown in Figure 2, the cover portion 216 is provided along the indoor side X2 surface of the guide rail 210b in the upper frame 21, and is provided from the indoor side X2 surface of the guide rail 210b to the inner surface of the indoor side end downward protrusion 2125 formed at the indoor side X2 end of the indoor side frame member 212.

[0024] The cover portion 216 is formed in a U-shaped frame shape that opens downward. An indoor side portion 216b of the cover portion 216 extends in the vertical direction along the outdoor side X1 portion of the edge member 101 of the building skeleton 100.

[0025] The angle portion 217 is provided at the end of the cover portion 216 on the indoor side X2, and protrudes further toward the indoor side X2 than the indoor side end downward protruding portion 2125 formed at the end of the indoor side X2 of the indoor side frame member 212. An indoor side protruding plate 217a formed at the lower end of the angle portion 217 is formed to extend in the projection direction at the end of the upper frame 21 on the indoor side X2.

[0026] As shown in FIG. 2 , the outdoor frame member 211 and the indoor frame member 212 are connected to each other by bridge reinforcement metal fittings 25 (bridge reinforcement members). The bridge reinforcement metal fittings 25 are arranged on the outer periphery (upper side, outside in the view direction) of the upper frame 21. The bridge reinforcement metal fittings 25 are arranged above the bridge member 213, spanning the indoor frame member 212, the bridge member 213, and the outdoor frame member 211. The bridge reinforcement metal fittings 25 connect the outdoor frame member 211 and the indoor frame member 212. The bridge reinforcement metal fittings 25 are made of a metal plate material formed from a metal material such as aluminum. By connecting the outdoor frame member 211 and the indoor frame member 212, the bridge reinforcement metal fittings 25 reinforce the bridge member 213 and ensure the strength of the bridge member 213. Note that in this embodiment, the bridge reinforcement metal fittings 25 are made of a metal material such as aluminum, but are not limited to this and may be made of a non-metal material such as carbon that can ensure strength equivalent to that of a metal material.

[0027] The bridge reinforcing brackets 25 are made up of piece-shaped members with a predetermined width in the vertical direction of the upper frame 21, and are arranged at multiple locations spaced apart in the vertical direction of the upper frame 21. This ensures that the bridge material 213 can block the transfer of heat from the exterior frame member 211 to the interior frame member 212, rather than forming the bridge reinforcing brackets 25 over the entire vertical length of the upper frame 21, and maintains thermal insulation performance.

[0028] The bridge reinforcement bracket 25 is formed in an L-shape in cross section and has a side fixing plate 251 that is fixed to the lower side of the indoor side X2 of the hollow frame portion 2111 of the outdoor frame member 211 of the upper frame 21 and extends in the vertical direction (frontward direction), and a frontward extending fixing plate 252 that extends from the lower end of the side fixing plate 251 toward the indoor side X2.

[0029] The side surface fixing plate 251 is formed on one side of the bridge reinforcing bracket 25 and is fixed with screws 251a to the indoor-side X2 side surface of the lower end of the hollow frame portion 2111 of the outdoor frame member 211 of the upper frame 21 with the plate disposed in a recess 2111a provided on the lower side of the indoor-side X2 side surface of the lower end of the hollow frame portion 2111 of the outdoor frame member 211 of the upper frame 21. Because the side surface fixing plate 251 is disposed in the recess 2111a in the indoor-side X2 side surface of the hollow frame portion 2111 of the upper frame 21, the side surface fixing plate 251 can be attached to the indoor-side X2 side surface of the hollow frame portion 2111 without protruding from the indoor-side X2 side surface of the hollow frame portion 2111 toward the indoor side X2.

[0030] The prospective direction extending fixing plate 252 is formed on the other side of the bridge reinforcing bracket 25, and is arranged above the prospective direction extending portion 2121 of the indoor side frame member 212 of the upper frame 21. The prospective direction extending fixing plate 252 is arranged overlapping the upper side of the prospective direction extending portion 2121 of the indoor side frame member 212 of the upper frame 21, and is fixed by screws 252a that pass through the prospective direction extending fixing plate 252 of the bridge reinforcing bracket 25 and the prospective direction extending portion 2121 of the indoor side frame member 212 of the upper frame 21 from the top to the bottom.

[0031] Head 252b of screw 252a is disposed on the upper surface of front-direction extending fixing plate 252 of bridge reinforcing bracket 25. Shank 252c of screw 252a is formed to extend downward from the lower part of head 252b, and is disposed so as to penetrate front-direction extending fixing plate 252 of bridge reinforcing bracket 25 and front-direction extending portion 2121 of indoor frame member 212 in the vertical direction.

[0032] Therefore, when bridge reinforcing bracket 25 is fixed to upper frame 21 with screw 252a, head 252b of screw 252a is positioned on the upper surface of forward-extending fixing plate 252 of bridge reinforcing bracket 25, which is positioned above indoor frame member 212 of upper frame 21. As a result, head 252b of screw 252a is not visible from below upper frame 21, improving the design.

[0033] As shown in Fig. 3, the vertical frame 23 has a composite structure in which an indoor-side resin cover material 232 and an inner-side resin cover material 233 made of resin are attached to the inner surface of the inner periphery of the frame at the end of the indoor-side X2 side of a metal frame body 231, which is the vertical frame body. Therefore, it has excellent heat insulation and moisture resistance.

[0034] The metal frame 231 is arranged on the outdoor side X1 of the vertical frame 23. The indoor side resin cover material 232 is attached to the end of the metal frame 231 on the indoor side X2. The resin inner surface resin cover material 233 is arranged on the indoor side X2 of the metal frame 231, and is provided on the inner surface of the vertical frame 23 closer to the outdoor side X1 than the indoor side resin cover material 232. The vertical frame 23 has a portion on the indoor side X2 end side fixed to an edge member 101 of the building skeleton 100 on the side of the opening 11.

[0035] The metal frame 231 is made of an extruded shape extruded in the longitudinal direction from a metal material such as aluminum. The metal frame 231 has a projection extending portion 2311 extending in the projection direction, a hollow portion 2312 formed on the outer circumferential side in the left-right direction on the outdoor side X1 of the projection extending portion 2311, an outdoor side end protruding piece 2313 protruding from the end of the projection extending portion 2311 on the outdoor side X1 to the inner circumferential side in the left-right direction, and an airtight material provided in a portion near the end of the projection extending portion 2311 on the outdoor side X1 and protruding from the portion on the indoor side X2 beyond the end of the projection extending portion 2311 on the outdoor side X1 to the inner circumferential side and attached to the vertical frame 33 of the outer shoji screen 3. 3313a abuts against, a central hook piece 2315 that protrudes inward from the inner peripheral surface near the center of the projection direction of the projection direction extending portion 2311, an indoor end hook piece 2316 that protrudes inward from the inner peripheral surface of the end of the projection direction extending portion 2311 on the indoor side X2 in the projection direction, and an indoor side hook piece 2317 that is provided in a portion of the projection direction extending portion 2311 closer to the end of the indoor side X2 in the projection direction and protrudes inward from the inner peripheral surface of the indoor side X2 further than the end of the indoor side X2.

[0036] Here, as shown in Figure 3, when the outer shoji screen 3 is in the closed position, the outer peripheral end of the vertical frame 33 on the door tip side of the outer shoji screen 3 is housed in the vertical frame 23 of the frame body 2. The configuration when the outer shoji screen 3 is in the closed position will be explained. First, the configuration of the vertical frame 33 on the door tip side of the outer shoji screen 3 will be explained.

[0037] As shown in Figure 3, the vertical frame 33 on the door end side of the outer shoji screen 3 is composed of a vertical frame main body 331 made of an extruded profile extruded longitudinally from a metal material such as aluminum, and a vertical frame cover member 332 made of resin that covers the side of the vertical frame main body 331 on the indoor side X2.

[0038] The vertical stile body 331 has a recessed frame portion 333 (recess, part mounting portion) formed at the outer peripheral end in the left-right direction, which is U-shaped and opens to the outer peripheral side in the left-right direction, and the outer peripheral side is recessed toward the inner peripheral side. The recessed frame portion 333 is a recess that is arranged opposite the vertical frame 23, and is formed in the outer peripheral part of the vertical stile 33 on the door tip side of the outer shoji 3, and is recessed toward the inner peripheral side in the left-right direction.

[0039] The recessed frame portion 333 is formed to extend in the vertical direction along the vertical direction of the vertical frame 33. As shown in Figures 1 and 3, a guide member 36 is attached to the vertical center side of the recessed frame portion 333 of the vertical frame 33. Reinforcing pieces 62 (described later) of a reinforcing member 6 attached to the vertical frame 23 of the frame body 2 are inserted into the upper and lower sides of the recessed frame portion 333 of the vertical frame 33 in the vertical direction.

[0040] The following describes the guide member 36 arranged in the recessed frame portion 333 of the vertical frame 33. The guide member 36 is formed in a piece shape with a predetermined width in the up-down direction of the vertical frame 33. As shown in FIG. 1, the guide member 36 is provided on the center side of the vertical frame 33 in the up-down direction (longitudinal direction).

[0041] The guide member 36 is formed of, for example, an elastically deformable resin material. As shown in Fig. 3, the guide member 36 has a rectangular parallelepiped base portion 361 that is long in the projection direction, and a bulge portion 362 that protrudes outward in the left-right direction from the outer peripheral surface of the base portion 361.

[0042] The base portion 361 is disposed on and fixed to the outer peripheral surface of the vertical frame extension portion 3311 on the inner circumferential side in the left-right direction of the recessed frame portion 333 of the vertical frame 33. The bulging portion 362 bulges outward in the left-right direction from a portion of the outer circumferential surface of the base portion 361 that is closer to the indoor side X2 in the forward direction.

[0043] The guide member 36 guides the outer shoji screen 3 to position itself in the forward direction so that when the outer shoji screen 3 is moved from the open position to the closed position, the bulge portion 362 comes into contact with the airtight material abutment piece 2314 of the vertical frame 23 on the door end side, and the airtight material 3313a provided at the tip of the vertical frame 33 abuts against the outside surface X1 of the airtight material abutment piece 2314 of the vertical frame 23.

[0044] As shown in Figure 3, the vertical frame main body 331 has a vertical frame projection direction extending portion 3311 formed at the bottom of the closed side of the U-shaped recessed frame portion 333 and extending in the projection direction, an outdoor inner periphery left-right extending portion 3312 extending from the outdoor side X1 end of the vertical frame projection direction extending portion 3311 to the inner periphery in the left-right direction, an outdoor outer periphery left-right extending portion 3313 extending from the outdoor side X1 end of the vertical frame projection direction extending portion 3311 to the outer periphery in the left-right direction, an outdoor outer periphery left-right protruding portion 3314 protruding from the indoor side X2 end of the vertical frame projection direction extending portion 3311 to the outer periphery in the left-right direction, and a frame main body side fitting portion 3315 formed on the outer periphery end side in the left-right direction of the outdoor outer periphery left-right protruding portion 3314.

[0045] The inner lateral end of the exterior inner lateral extension 3312 engages with the exterior X1 portion of the grating channel 351, which holds the lateral end of the glass or other surface material 35. An airtight material 3313a is attached to the interior X2 surface of the outer lateral end of the exterior outer lateral extension 3313. The airtight material 3313a protrudes from the interior X2 surface of the exterior outer lateral extension 3313 toward the interior X2. When the exterior screen 3 is in the closed position, the interior X2 tip of the airtight material 3313a is pressed against the exterior X1 surface of the airtight material abutment piece 2314 of the vertical frame 23.

[0046] The stile cover member 332 has a hollow portion 3321, an outdoor fitting portion 3322 provided at the outdoor side X1 end of the hollow portion 3321, an indoor side left-right extending portion 3323 extending inward from the indoor side X2 end of the hollow portion 3321, and an inner side prospective extending portion 3324 formed in a straight line extending from the inner side end of the indoor side left-right extending portion 3323 to both the outdoor side X1 and the indoor side X2. A stile body side fitting portion 3315 of the stile body 331 of the stile 33 fits into the outdoor side fitting portion 3322.

[0047] The inner surface of the inner projection extending portion 3324 constitutes the inner projection end portion 33a. The inner projection end portion 33a is the innermost end portion in the left-right direction of the vertical frame 33 on the door tip side. The outside X1 end portion of the inner projection extending portion 3324 engages with the inside X2 portion of the grating channel 351 that holds the left-right end portion of the face material 35 such as glass. The inside X2 end portion of the inner projection extending portion 3324 serves as a handle when opening and closing the outer shoji screen 3.

[0048] 3, the inner peripheral end 33a of the vertical frame 33 is disposed on an end line Lb extending in the projection direction at the innermost left-right end of the vertical frame 33, and is disposed along an opening line La (opening line) on the indoor side X2 of the frame body 2. As for the opening line La on the indoor side X2 of the frame body 2, the projection surface 200a extending in the projection direction of the inner peripheral end in the left-right direction of the indoor side cover part 2322 of the vertical frame 23 on the door end side is disposed at the position of the innermost left-right end of the opening 200 of the frame body 2, and a line along the projection surface 200a becomes the opening line La on the indoor side X2 of the vertical frame 23 on the door end side of the frame body 2.

[0049] Therefore, when viewed from the inside X2, the opening line La on the inner circumferential side of the opening 200 of the frame body 2 in the left-right direction is aligned with the end line Lb extending in the forward direction of the inner circumferential end 33a of the vertical frame 33, and the vertical frame 33 of the outer shoji screen 3 does not protrude significantly toward the opening 200 of the frame body 2, thereby maintaining the design.

[0050] In addition, when the inner peripheral end 33a of the vertical frame 33 is positioned along the opening line La on the indoor side X2 of the frame body 2, it means that the inner peripheral end 33a of the vertical frame 33 and the opening line La on the indoor side X2 of the frame body 2 are in a straight line, and even if there is a slight misalignment between their positions in the left-right direction, this slight misalignment that does not impair the design is included in the inner peripheral end 33a of the vertical frame 33 being positioned along the opening line La on the indoor side X2 of the frame body 2.

[0051] Next, the vertical frame 23 will be described. A reinforcing member 6 is provided on the inner peripheral surface of the metal frame body 231 of the vertical frame 23. The reinforcing member 6 reinforces the strength of the vertical stile 33 of the outer shoji screen 3 by restricting movement of the vertical stile 33 of the outer shoji screen 3 in the projection direction when the outer shoji screen 3 is in the closed position. The reinforcing member 6 is arranged and fixed to the metal frame body 231 of the vertical frame 23 at a position that can reinforce the strength of the vertical stile 33. For example, the reinforcing member 6 is arranged and fixed to a position between the airtight material abutment piece 2314 and the center hook piece 2315 on the projection surface on the inner peripheral side of the projection direction extension portion 2311 of the metal frame body 231 of the vertical frame 23.

[0052] A plurality of reinforcing members 6 are provided at intervals in the up-down direction (longitudinal direction) of the vertical frame 23. In this embodiment, as shown in Fig. 1, the plurality of reinforcing members 6 are arranged at positions that avoid the positions where the guide members 36 are arranged in the up-down direction of the vertical frame 23, and are arranged closer to both ends than the center of the vertical frame 23 (both ends of the area where the shoji screen is arranged in the vertical frame 23).

[0053] 3, the reinforcing member 6 is formed in an L-shape in cross section. The reinforcing member 6 has an attachment piece 61 arranged along the inner peripheral surface of the projection-direction extending portion 2311 of the vertical frame 23, and a reinforcing piece 62 extending inward in the left-right direction from the end of the attachment piece 61 on the exterior side X1. The reinforcing member 6 may be formed from a metal material such as aluminum, or from a non-metal material such as carbon that can ensure strength equivalent to that of a metal material.

[0054] The mounting piece 61 is fixed to the projection-direction extending portion 2311 of the vertical frame 23 with a screw 611. The reinforcing piece 62 extends from the vertical frame 23 side toward the inner periphery in the left-right direction, and is disposed opposite the outer periphery end of the vertical stile 33.

[0055] The reinforcing piece 62 is formed to extend inward in the left-right direction, and when the outer screen 3 is in the closed position, it is located inside the recessed frame portion 333 formed on the outer periphery of the vertical frame 33 on the inner periphery in the left-right direction. In this embodiment, the reinforcing member 6 is fixed with the screw 611, but this is not limited to this. The reinforcing member 6 may also be fixed by attaching it with, for example, an adhesive or double-sided tape.

[0056] Conventionally, when the opening 11 is large and fittings are placed in the opening 11, the rigidity of the vertical stiles is increased by, for example, widening the width of the vertical stiles of the shoji screen to ensure wind pressure resistance and prevent the vertical stiles from bending in the wind. Therefore, if the width of the vertical stiles is widened, when the shoji screen is closed and viewed from inside the room, the line of the opening in the frame body and the line of the glass embedded in the vertical stiles of the shoji screen do not align, and the vertical stiles of the shoji screen protrude to the left and right inward of the opening in the frame body, making them visible from inside the room, which could reduce the design quality.

[0057] In contrast to this, in this embodiment, a reinforcing member 6 is provided on the vertical frame 23. This restricts the movement of the outer screen 3 in the viewing direction when the outer screen 3 is in the closed position, thereby reinforcing the strength of the outer screen 3. Therefore, wind pressure resistance can be ensured without making the vertical frame 33 thicker, etc.

[0058] The indoor-side resin cover material 232 is attached to the end portion of the metal frame 231 on the indoor side X2. The indoor-side resin cover material 232 extends over the entire length in the direction in which the vertical frame 23 extends. The indoor-side resin cover material 232 has a mounting plate 2321, an indoor-side cover portion 2322, and an indoor-side extension portion 2323.

[0059] The mounting plate 2321 is attached by hooking and engaging with the indoor end hook piece 2316 and the indoor side hook piece 2317 on the inner surface of the indoor side X2 end of the forward extension portion 2311 of the vertical frame 23.

[0060] The indoor cover part 2322 is formed to extend a predetermined length from the end of the indoor side X2 of the mounting plate 2321 toward the inner periphery in the left-right direction. The indoor cover part 2322 covers the vertical frame 33 of the outer screen 3 so that it cannot be seen from the indoor side X2 at the opening of the frame body 2. The visible surface 200a extending in the visible direction of the inner periphery end of the indoor cover part 2322 in the left-right direction is the position of the innermost end in the left-right direction of the opening 200 of the frame body 2, and the line along the visible surface 200a is the opening line La on the indoor side X2 of the frame body 2.

[0061] The indoor side extending portion 2323 is formed by extending from a portion of the indoor side cover portion 2322 near the inner periphery side in the left-right direction to the indoor side X2.

[0062] The inner surface resin cover material 233 is positioned adjacent to the outdoor side X1 of the indoor side resin cover material 232, and covers the inner surface of the inner periphery of the vertical frame 23 in the left-right direction between the indoor side resin cover material 232 and just before the outer shoji screen 3 is positioned on the indoor side X2 of the vertical frame 23.

[0063] The inner surface resin cover material 233 has a first hollow portion 2331 and a second hollow portion 2332 arranged side by side from the outer periphery to the inner periphery in the left-right direction on the outside side X1 of the inner surface resin cover material 233, a third hollow portion 2333 arranged side by side on the indoor side X2 of the second hollow portion 2332 and having a shorter left-right length than the second hollow portion 2332, an outdoor side end protrusion 2334 protruding outward in the left-right direction from the end of the second hollow portion 2332 on the outside side X1, an indoor side end protrusion 2335 protruding outward in the left-right direction from the end of the third hollow portion 2333 on the indoor side X2, an outdoor side protrusion 2336 protruding outward in the left-right direction from the end of the first hollow portion 2331 on the outside side X1, and an indoor side protrusion 2337 protruding outward in the left-right direction from the end of the first hollow portion 2331 on the indoor side X2.

[0064] The inner surface resin cover material 233 is attached to the inner surface of the vertical frame 23 by fitting the outdoor end protrusion 2334 and the outdoor protrusion 2336 to sandwich the central hook piece 2315 of the metal frame body 231 of the vertical frame 23 at the outer lateral portion of the outdoor end X1, and by fitting the outer lateral tip of the indoor end protrusion 2335 to the indoor resin cover material 232 at the indoor end X2.

[0065] According to this embodiment, the following effects are achieved: The fitting 1 of this embodiment comprises a frame body 2 having a vertical frame 23, an outer shoji screen 3 arranged within the frame body 2 and having a vertical stile 33, and a reinforcing member 6 attached to the vertical frame 23 to reinforce the strength of the outer shoji screen 3 by restricting movement of the outer shoji screen 3 in the viewing direction when the outer shoji screen 3 is in the closed position, and the inner peripheral end 33a of the vertical stile 33 is arranged along the opening line La on the indoor side X2 of the frame body 2.

[0066] Therefore, the reinforcing member 6 attached to the vertical frame 23 restricts the movement of the outer shoji screen 3 in the viewing direction when the outer shoji screen 3 is in the closed position, thereby reinforcing the strength of the outer shoji screen 3, thereby ensuring wind pressure resistance without making the vertical frame 33 thicker. Also, because the inner peripheral end 33a of the vertical frame 33 is positioned along the opening line La of the frame body 2 on the indoor side X2, the effective opening area of ​​the window as fitting 1 can be increased. This makes it possible to achieve both improved design and improved wind pressure resistance without narrowing the effective opening area of ​​the window as fitting 1. Therefore, strength can be ensured while maintaining design.

[0067] In addition, in this embodiment, multiple reinforcing members 6 are provided at intervals in the vertical direction of the vertical frame 23. As a result, the strength of the outer shoji screen 3 can be further reinforced by the reinforcing members 6 at multiple locations in the vertical direction of the vertical frame 23, thereby ensuring optimal strength.

[0068] In addition, in this embodiment, the two reinforcing members 6 are positioned closer to both ends than the vertical center of the vertical frame 23. As a result, the strength of the outer shoji screen 3 can be further reinforced by the reinforcing members 6 at both ends closer to the upper and lower ends than the vertical center of the vertical frame 23, thereby ensuring optimal strength.

[0069] Furthermore, in this embodiment, a guide member 36 is provided at the center of the vertical stile 33, and the reinforcing member 6 is placed at a position that avoids the position where the guide member 36 is placed in the vertical direction of the vertical frame 23. As a result, the strength of the outer screen 3 can be reinforced by the reinforcing member 6 in places where the guide member 36 is not placed, and the strength of the outer screen 3 can be suitably ensured without impeding the function of the guide member 36.

[0070] In this embodiment, the reinforcing member 6 has a reinforcing piece 62 extending from the vertical frame 23 side toward the inner periphery in the front direction, and the reinforcing piece 62 is located inside a recessed frame portion 333 formed on the outer periphery of the vertical stile 33 and recessed toward the inner periphery in the front direction when the outer shoji screen 3 is in the closed position. As a result, even if the outer shoji screen 3 is blown by the wind and the vertical stile 33 side of the outer shoji screen 3 is bent so as to move toward the outside X1, the movement of the reinforcing member 6 toward the outside X1 is restricted by the member located on the outer periphery in the left-right direction on the inside X2 of the recessed frame portion 333, and further movement toward the outside X1 can be prevented.

[0071] In addition, in this embodiment, the frame body 2 has an upper frame 21, which has an indoor frame member 212, an outdoor frame member 211, and a bridge member 213 arranged between the indoor frame member 212 and the outdoor frame member 211, and is equipped with a bridge reinforcement bracket 25 arranged above the bridge member 213, spanning the indoor frame member 212, the bridge member 213, and the outdoor frame member 211, and connecting the indoor frame member 212 and the outdoor frame member 211.

[0072] Therefore, by connecting the outdoor frame member 211 and the indoor frame member 212, the bridge reinforcement bracket 25 reinforces the bridge material 213, thereby ensuring the strength of the bridge material 213. In addition, the prospective-direction-extending fixing plate 252 of the bridge reinforcement bracket 25 can be fixed to the prospective-direction-extending portion 2121 of the indoor frame member 212 of the upper frame 21 by the screw 252a from above, so that the head 252b of the screw 252a is positioned on the upper surface of the prospective-direction-extending fixing plate 252 of the bridge reinforcement bracket 25 positioned above the indoor frame member 212 of the upper frame 21. As a result, the head 252b of the screw 252a is not visible from below the upper frame 21, improving the design.

[0073] Next, a fitting 1A of a second embodiment will be described with reference to Figures 4 to 6. The fitting 1A of the second embodiment is primarily used for fire prevention, and differs from the fitting 1 of the first embodiment mainly in that it is provided with a reinforcing plate 218 that reinforces the cover portion 216 provided along the surface of the indoor side X2 of the guide rail 210b in the upper frame 21, as shown in Figures 4 and 5, and in the mounting structure of the resin cover material 233 on the inner surface of the vertical frame 23, as shown in Figure 6. In the second embodiment, differences from the first embodiment will be mainly described, and in the description of the second embodiment, configurations similar to those in the first embodiment will be assigned the same reference numerals and their description will be omitted.

[0074] A description will be given of a structure in which a reinforcing plate 218 is provided to reinforce the cover portion 216 provided along the surface of the indoor side X2 of the guide rail 210b in the upper frame 21. As shown in Fig. 5, the cover portion 216 provided along the surface of the indoor side X2 of the guide rail 210b in the upper frame 21 is formed in a U-shaped frame shape that opens downward, similar to the first embodiment.

[0075] As shown in Figures 4 and 5, the top panel 216a of the cover portion 216 and the indoor frame member 212 of the upper frame 21 arranged above the top panel 216a are fixed together with a reinforcing plate 218 arranged below the top panel 216a by being fastened together from below with screws 219. The reinforcing plate 218 is formed in a plate shape that has a thickness in the vertical direction and extends in the front direction with a predetermined width in the front direction. A plurality of reinforcing plates 218 are provided at intervals from each other in the vertical direction (longitudinal direction) of the upper frame 21.

[0076] Because the fitting 1A of the second embodiment is primarily used for fire prevention, the bridge reinforcing metal fittings 25 (see FIG. 2) are made of metal plates formed from a metal material such as aluminum. The bridge reinforcing metal fittings 25 are not shown because they have the same configuration as those in FIG. 2 of the first embodiment. However, as in the first embodiment, they connect the outdoor frame member 211 and the indoor frame member 212, reinforcing the bridge member 213 and ensuring its strength. Furthermore, because the bridge reinforcing metal fittings 25 are made of a metal material such as aluminum, even if the resin-made bridge member 213 melts in the event of a fire, separation between the outdoor frame member 211 and the indoor frame member 212 can be prevented because they are made of a metal material and connect the outdoor frame member 211 and the indoor frame member 212. This ensures fire resistance.

[0077] 6, similar to the first embodiment, a reinforcing member 6 is provided on the inner peripheral surface of the metal frame 231 of the vertical frame 23. The fitting 1A of the second embodiment is mainly used for fire prevention purposes and is therefore made of a metal material such as aluminum.

[0078] The following describes the mounting structure of the inner surface resin cover material 233 of the vertical frame 23. As shown in Fig. 6, through holes 2333a into which screws 28 and a screwdriver (not shown) can be inserted are formed on the inner peripheral surface in the left-right direction of the third hollow portion 2333 of the inner surface resin cover material 233. A front-direction extending plate 2333b extending in the front direction is formed on the outer peripheral surface in the left-right direction of the third hollow portion 2333.

[0079] As in the first embodiment, the inner surface resin cover material 233 is attached to the inner peripheral surface of the vertical frame 23 by having the outdoor end protrusion 2334 and the outdoor protrusion 2336 fit together to sandwich the central hook piece 2315 of the metal frame body 231 of the vertical frame 23 at the outer lateral side of the end on the outdoor side X1, and the outer lateral side tip of the indoor end protrusion 2335 fit into the indoor side resin cover material 232 at the end on the indoor side X2, so that in addition to being attached to the inner peripheral surface of the vertical frame 23, the inner surface resin cover material 233 is attached to the indoor side X2 part of the inner peripheral side of the forward extending portion 2311 of the metal frame body 231 using a metal core material 26 and a metal mounting profile 27 and screws 28, 29.

[0080] The core material 26 is made of metal and formed in a plate shape extending in the up-down direction (longitudinal direction) of the vertical frame 33. The core material 26 is arranged inside the third hollow portion 2333 along the inner peripheral surface in the left-right direction of a projection direction extending plate 2333b formed on the outer peripheral side in the left-right direction of the third hollow portion 2333.

[0081] The mounting member 27 is made of metal, and is arranged on the outer periphery of a projection direction extending plate 2333b formed on the outer periphery in the left-right direction of the third hollow portion 2333. The mounting member 27 has a cover material side fixing plate 271 fixed to the inner surface resin cover material 233, a vertical stile side fixing plate 273 fixed to the vertical frame 23, and an extending connecting plate 272 connecting the cover material side fixing plate 271 and the vertical stile side fixing plate 273.

[0082] The cover material side fixing plate 271 is formed to extend in the projection direction and is disposed along the outer peripheral surface of the projection direction extending plate 2333b formed on the outer peripheral side in the left-right direction of the third hollow portion 2333. The cover material side fixing plate 271 is fastened together and fixed by screws 28 that penetrate the core material 26, the projection direction extending plate 2333b of the third hollow portion 2333, and the cover material side fixing plate 271 in the left-right direction.

[0083] The screw 28 is inserted into the third hollow portion 2333 through a through hole 2333a formed on the inner surface of the third hollow portion 2333 in the left-right direction, and by tightening the screw 28 with a screwdriver (not shown) through the through hole 2333a, the screw 28 penetrates from the inner side in the left-right direction to the outer side, through the core material 26, the forward direction extending plate 2333b extending in the forward direction and arranged on the outer side of the third hollow portion 2333 in the left-right direction, and the cover material side fixing plate 271, and is tightened together to fasten them together.

[0084] The extended connecting plate 272 has an extended plate 2721 extending from the outside-side X1 end of the cover material side fixing plate 271 to the outer periphery in the left-right direction, and a curved plate 2722 that curves from the outer periphery end of the extended plate 2721 in the left-right direction from the inner periphery to the outer periphery in the left-right direction, from the outside-side X1 to the inside-side X2.

[0085] The stile-side fixing plate 273 is connected to the indoor-side X2 end of the curved plate 2722 of the extending connecting plate 272. The stile-side fixing plate 273 is formed extending from the indoor-side X2 end of the curved plate 2722 of the extending connecting plate 272 to the indoor-side X2. The stile-side fixing plate 273 is formed extending in the projection direction, and is disposed along the inner peripheral surface in the left-right direction of the mounting plate 2321 of the indoor-side resin cover material 232 attached to the vertical frame 23. The stile-side fixing plate 273, the mounting plate 2321 of the indoor-side resin cover material 232, and the projection-direction extending portion 2311 of the vertical frame 23 are fastened together and fixed with screws 29.

[0086] The procedure for attaching the inner surface resin cover material 233 to the inner peripheral surface of the metal frame body 231 of the vertical frame 23 in the left-right direction of the projected direction extending portion 2311 of the vertical frame 23 using a metal core material 26 and a metal mounting shape 27 will be described.

[0087] First, with the resin indoor-side resin cover material 232 attached by fitting to the inner periphery in the left-right direction of the end of the indoor-side X2 side of the metal frame body 231 of the vertical frame 23, the vertical stile-side fixing plate 273 of the mounting frame 27 is placed along the inner periphery in the left-right direction of the mounting plate 2321 of the indoor-side resin cover material 232 attached to the vertical frame 23. In this state, the screw 29 is moved from the inner periphery in the left-right direction toward the outer periphery, and the screw 29 is passed through the vertical stile-side fixing plate 273 of the mounting frame 27, the mounting plate 2321 of the indoor-side resin cover material 232, and the projection-direction extending portion 2311 of the vertical frame 23 and tightened together to fix it to the vertical frame 23.

[0088] Next, the inner surface resin cover material 233 is attached to the vertical frame 23 by fitting. Then, the core material 26 is inserted into the third hollow portion 2333 of the inner surface resin cover material 233. Note that the core material 26 may be prepared by being placed inside the third hollow portion 2333 in advance.

[0089] Next, the core material 26 arranged in the third hollow portion 2333 of the inner surface resin cover material 233 is fixed to the mounting frame 27 with the screw 28. Specifically, the screw 28 and a screwdriver (not shown) are inserted through the through hole 2333a, and the screw 28 is rotated with the screwdriver to penetrate the core material 26, the projection direction extending plate 2333b of the third hollow portion 2333, and the cover material side fixing plate 271 from the inner peripheral side to the outer peripheral side in the left-right direction, and tighten them together, thereby fixing the inner surface resin cover material 233 to the mounting frame 27.

[0090] According to the above mounting structure of the inner surface resin cover material 233, the inner surface resin cover material 233 is fixed to the vertical frame 23 with screws 28, 29 using a metal core material 26 and a metal mounting shape 27.Therefore, even if the inner surface resin cover material 233 melts in the event of a fire, the inner surface resin cover material 233 and the vertical frame 23 are connected by the metal core material 26 and the metal mounting shape 27, so that it is possible to prevent or delay the inner surface resin cover material 233 from falling toward the opening 200 of the frame body 2.

[0091] Next, a modified reinforcing member 6A will be described. The same components as those in the above embodiment will be given the same reference numerals, and the description thereof will be omitted.

[0092] As shown in Figure 7, the modified reinforcing member 6A has an attachment piece 61 arranged along the inner peripheral surface of the extension portion 2311 in the forward direction of the vertical frame 23, and a reinforcing piece 65 extending from the outside X1 end of the attachment piece 61 to the inner peripheral side in the forward direction.

[0093] Reinforcing piece 65 is formed in the shape of a plate in which plate material 651 is folded so that it overlaps twice. Therefore, reinforcing piece 65 has a shape in which plate material 651 is folded and plate material 651 is overlapped twice. Therefore, by forming reinforcing piece 65 in the shape of overlapping plates rather than configuring it from a single plate material with a simple configuration, it is possible to improve the strength of reinforcing member 6A and further improve the wind pressure resistance performance of reinforcing member 6A.

[0094] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0095] For example, in the above embodiment, the configuration around the upper frame, vertical frame and vertical stile of the shoji screen was mainly described in terms of the configuration on the door edge side of the outer shoji screen 3, but this is not limited to this and may also be applied to the configuration on the door edge side of the inner shoji screen 4.

[0096] In the above embodiment, the reinforcing members 6, 6A are configured to be spaced apart from each other in the vertical direction (longitudinal direction) of the vertical frame 23, but the arrangement positions and number of the reinforcing members 6, 6A are not limited to the examples described in the above embodiment, and they may be arranged in any position and number on the metal frame body 231 of the vertical frame 23 as long as they are capable of reinforcing the strength of the vertical frame 33.
