Description

[Technical Field]

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

[0002] In building fixtures, the wind load received by the shoji screen is transmitted from the shoji frame to the frame and then to the building's framework. In the case of a sliding sash with an inner and outer shoji screen sliding together, as disclosed in Patent Document 1, the wind load is transmitted from the upper frame of the shoji screen to the upper frame, from the lower frame of the shoji screen to the lower frame, and from the door edge frame of the shoji screen to the vertical frame. At the intersection where the inner and outer shoji screens overlap, the wind load is transmitted from the upper end of the screen to the upper frame and from the lower end of the screen to the lower frame.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-163658 Summary of the Invention [Problem to be solved by the invention]

[0004] The wind load transmitted from the stile to the upper and lower frames acts more locally on the upper and lower frames than the wind load transmitted from the upper and lower frames to the upper and lower frames. For this reason, on higher floors of a building where the wind load is greater, the wind load transmitted from the stile to the upper and lower frames may cause the frame to deform and reduce wind pressure resistance.

[0005] The present disclosure aims to provide a building fixture that can prevent deformation of the frame body and increase wind pressure resistance. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objectives, the building fixture of the present disclosure comprises a frame body arranged along the edge of an opening in a main body, and a plurality of shoji screens slidably supported on the frame body, the plurality of shoji screens having a face material and a stile arranged on the outer periphery of the face material, the stile having an upper stile, a lower stile and a joint stile, and at least one of the plurality of shoji screens has a load transmission member arranged from the upper stile to the joint stile and / or from the lower stile to the joint stile, the load transmission member facing the frame body in the indoor / outdoor direction.

The indoor-side panel 356, the intermediate panel 357, and the outdoor-side panel 358 each protrude from the groove bottom panel 353 to one side in the width direction, i.e., the side opposite the side where the glass groove 35a is formed. The indoor-side panel 356, the intermediate panel 357, and the outdoor-side panel 358 are arranged in this order from the indoor side to the outdoor side, with a gap between them. The indoor-side panel 356 is located closer to the outdoor side than the indoor-side end of the groove bottom panel 353. The outdoor-side panel 358 is located closer to the indoor side than the outdoor-side end of the groove bottom panel 353. The indoor-side panel 356 and the outdoor-side panel 358 protrude from the intermediate panel 357 to one side in the width direction.

[0033] The outdoor side plate portion 358 extends from the groove bottom plate portion 353 to one side in the width direction, then bends toward the outdoors, extends toward the outdoors, then bends toward one side in the width direction, and extends toward one side in the width direction again. The outer plate portion 359 is formed in a flat plate shape. The plate surface of the outer plate portion 359 faces the width direction. The outer plate portion 359 is disposed between the indoor side plate portion 356 and the outdoor side plate portion 358. The indoor side end of the outer plate portion 359 is connected to a middle portion in the width direction of the indoor side plate portion 356. The outdoor side end of the outer plate portion 359 is connected to a middle portion in the width direction of the outdoor side plate portion 358.

[0034] As shown in Figure 9, the upper frame 33 is joined to the upper end of the door stile 35 of the inner shoji screen 3 from one side in the width direction. The upper end of the door stile 35 and the upper end of the upper frame 33 are positioned at approximately the same height. Figure 9 is a perspective view of the part where the door stile 35 and the upper frame 33 of the inner shoji screen 3 are joined, viewed from the indoor side. A cutout portion 35d is formed in the upper end of the indoor groove side plate portion 354 and the groove bottom plate portion 353 of the door stile 35 shown in Figure 3, on the indoor side of the indoor side plate portion 356. The position where the cutout portion 35d is formed is shown by a dashed line in Figure 3. The lower end of the cutout portion 35d is approximately the same height as the groove bottom plate portion 333 of the upper frame 33 to which it is joined. The indoor side panel portion 336 of the upper frame 33 is inserted into the glass groove portion 35a of the door sill 35, and one end portion in the width direction contacts the groove bottom panel portion 353 from the other side in the width direction. The indoor side panel portion 336 of the upper frame 33 is positioned in a position that is aligned in the width direction with the indoor side panel portion 356 of the groove bottom panel portion 353. The indoor side panel portion 336 is positioned on the outdoor side of the cutout portion 35d. In Figure 3, the area near the end of the indoor side panel portion 336 of the upper frame 33 on the door sill 35 side is shown by a dashed line.

[0035] As shown in Figures 9 to 12, a safety cap 91 is attached to the cutout 35d at the upper end of the door stile 35. A fixing hole 336a that penetrates in the indoor / outdoor direction and is used to fix the safety cap 91 is formed in the outdoor side of the cutout 35d in the indoor side panel 336, i.e., in the end on one side in the width direction. When viewed from the indoor / outdoor direction, the fixing hole 336a has a rectangular shape with rounded corners.

[0036] As shown in Figures 13 to 15, the safety cap 91 has a cap body 911, a fixing plate 912, and a fixing protrusion 913. The cap body 911 is flat. A step 911a is formed on the edge of the cap body 911 to match the shape of the door stile 35. The cap body 911 is arranged along the bottom of the cutout 35d with the plate surface oriented horizontally (see Figure 9). The fixing plate 912 extends upward from the outdoor-side edge of the cap body 911. The fixing plate 912 is flat. A step 912a is formed on the edge of the fixing plate 912 to match the shape of the upper frame 33. The fixing plate 912 is arranged along the indoor-side surface of the indoor-side plate 336 of the upper frame 33. The fixing plate 912 is arranged in a position overlapping the fixing hole 336a. The fixing protrusion 913 protrudes toward the outside from the fixing plate 912. The fixing protrusion 913 is inserted into the fixing hole 336a.

[0037] The fixing protrusion 913 has a guide portion 914 and a pull-out prevention portion 915. The guide portion 914 has a guide plate portion 914a and a guide piece 914b. See Figure 4 for the guide piece 914b. The guide plate portion 914a is flat. The guide plate portion 914a protrudes from the fixing plate portion 912 toward the outdoor side with its plate surface oriented horizontally. The width dimension of the guide plate portion 914a is approximately the same as the width dimension of the fixing hole portion 336a. The guide piece 914b protrudes upward from the upper surface of the guide plate portion 914a. The upper edge portion of the guide piece 914b extends horizontally from the indoor side toward the indoor side and further extends downward toward the outdoor side. The indoor side end of the guide piece 914b contacts the outdoor side surface 912b of the fixing plate portion 912. The outdoor end of the guide piece 914b is located at the middle position in the indoor / outdoor direction of the guide plate portion 914a. Two guide pieces 914b are provided with a gap in the width direction.

[0038] The pull-out prevention portion 915 has an inclined piece 915a and a support piece 915b. The support piece 915b is flat. The support piece 915b protrudes downward from the lower surface of the guide plate portion 914a. The indoor / outdoor dimension of the support piece 915b is approximately the same as the indoor / outdoor dimension of the guide plate portion 914a. The indoor ends of the support pieces 915b are connected to the outdoor surface 912b of the fixing plate portion 912. Two support pieces 915b are provided spaced apart in the width direction. The inclined piece 915a extends obliquely from the outer widthwise surfaces of the two support pieces 915b on the opposite sides of the two support pieces 915b toward the outside in the width direction, gradually moving inward toward the interior of the building. The inclined piece 915a is not connected to the guide plate portion 914a. A gap is formed between the upper ends of the inclined pieces 915a and the lower surface of the guide plate portion 914a. When the pull-out prevention portion 915 is pressed from the outside in the width direction, the inclined piece 915a elastically deforms so as to approach the support piece 915b. The tip of the inclined piece 915a protrudes outward in the width direction beyond the guide portion 914.

[0039] When the fixing protrusion 913 is inserted into the fixing hole 336a, the guide piece 914b moves along the upper edge of the fixing hole 336a, thereby inserting the fixing protrusion 913 into the fixing hole 336a. As described above, the tip of the inclined piece 915a protrudes outward in the width direction beyond the guide piece 914. Therefore, when the fixing protrusion 913 is inserted into the fixing hole 336a, the inclined piece 915a of the pull-out prevention portion 915 abuts the side edge of the fixing hole 336a, and the inclined piece 915a elastically deforms so as to approach the support piece 915b. When the fixing protrusion 913 is inserted into the fixing hole 336a, the inclined piece 915a moves away from the side edge of the fixing hole 336a, and the elastic deformation of the pull-out prevention portion 915 is restored. As a result, if the fixing protrusion 913 tries to come out of the fixing hole 336a, for example, because the safety cap 91 is pulled indoors, the inclined piece 915a will come into contact with the indoor side panel 336, preventing it from coming out of the fixing hole 336a. When the fixing protrusion 913 is inserted into the fixing hole 336a, the fixing plate 912 is positioned along the indoor side surface of the indoor side panel 336 of the upper frame 33. The outdoor side surface of the fixing plate 912 and the indoor side surface of the indoor side panel 336 of the upper frame 33 may be adhered with double-sided tape or the like.

[0040] The lower frame 34 is joined to the lower end of the door frame 35 of the inner shoji screen 3 from one side in the width direction. As shown in Figures 16 to 18, a notch 35e is formed at the lower end of the indoor portion of the door frame 35 of the inner shoji screen 3, just like the upper end, and a safety cap 92 is attached. The indoor side panel 346 of the lower frame 34 is located on the outdoor side of the notch 35e. A fixing hole 346b that penetrates the indoor / outdoor direction and is used to fix the safety cap 92 is formed in the outdoor side of the notch 35e of the indoor side panel 346, i.e., the end on one side in the width direction. The fixing hole 346b has a rectangular shape with rounded corners when viewed from the indoor / outdoor direction. Figure 17 is a view of the frame 31 from below.

[0041] The safety cap 92 attached to the lower end of the door stile 35 has substantially the same configuration as the safety cap 91 attached to the upper end of the door stile 35, except for the dimensions and attachment orientation. The safety cap 92 attached to the lower end of the door stile 35 has a cap main body 921, a fixing plate 922, and a fixing protrusion 923 that are similar to the cap main body 911, fixing plate 912, and fixing protrusion 913 of the safety cap 91 attached to the upper end of the door stile 35. The fixing plate 922 of the safety cap 92 extends downward from the outdoor-side edge of the cap main body 921. The fixing plate 922 is arranged along the indoor-side surface of the indoor-side plate 346. The fixing protrusion 923 protrudes from the fixing plate 922 to the outdoor side. The fixing protrusion 923 is inserted into the fixing hole 346b from the indoor side.

[0042] The fixed protrusion 923 has a guide portion 924 and a pull-out prevention portion 925 similar to the guide portion 914 and the pull-out prevention portion 915 of the fixed protrusion 913. The guide portion 924 of the fixed protrusion 923 is provided below the pull-out prevention portion 925.

[0059] An upper load transmission member 51 is attached to the fitting 1 at the joint between the upper frame 33 and the joining frame 36 of the inner shoji screen 3, that is, at a position spanning from the upper frame 33 to the joining frame 36, and facing the upper frame 21 in the indoor / outdoor direction. As a result, in strong winds, the upper frame 33 and joining frame 36 come into contact with the upper frame 21 via the upper load transmission member 51 near the joining section 12, where wind loads tend to act locally, and the wind load can be transmitted between the upper frame 33 and the upper frame 21. This allows the wind load acting on the joining section 12 to be distributed to the upper frame 33 and the upper frame 21 near the joining section 12. As a result, deformation of the frame body 2 due to localized wind loads can be suppressed, improving wind pressure resistance.

[0060] A lower load transmission member 52 is attached to the fitting 1 at the joint between the lower frame 34 and the joining frame 36 of the inner shoji screen 3, i.e., at a position spanning from the lower frame 34 to the joining frame 36 and facing the lower frame 22 in the indoor / outdoor direction. This allows the lower frame 34 and joining frame 36 to come into contact with the lower frame 22 via the lower load transmission member 52 in the vicinity of the joining section 12, where wind loads tend to act locally, and transmits the wind load between the lower frame 34 and the lower frame 22. This allows the wind load acting on the joining section 12 to be distributed to the lower frame 34 and the lower frame 22 near the joining section 12. As a result, deformation of the frame 2 due to localized wind loads can be suppressed, improving wind pressure resistance. The upper load transmission member 51 and the lower load transmission member 52 are installed only in positions where wind loads tend to act locally. Therefore, the building fixture 1 can improve wind pressure resistance while reducing installation costs compared to when components that transmit load between the frame body 2 and the frame 31 are installed around the entire frame 31 or over the entire upper frame 33 and lower frame 34.

[0061] The upper load transmission member 51 is provided on the outdoor side of the upper frame 33 and the joint frame 36. Load can be transmitted between the frame body 2 and the frame 31 via the upper load transmission member 51 on the outdoor side of the upper frame 33 and the joint frame 36.

[0062] The lower load transmission member 52 is provided at the portion facing the inner shoji lower rail 221 of the lower frame 22 in the lower stile 34 and the joint stile 36. The load acting on the stile 31 can be transmitted to the inner shoji lower rail 221, which has high strength.

[0063] The frame 31 of the inner shoji screen 3 is assembled vertically, with the horizontal frames of the upper frame 33 and lower frame 34 and the vertical frames of the door edge frame 35 and the door join frame 36. In fittings 1 where the frames are assembled vertically, the wind pressure resistance can be improved.

[0064] The shoji screen on which the upper load transmission member 51 and the lower load transmission member 52 are provided is the inner shoji screen 3. Load can be transmitted between the inner shoji screen 3 and the frame body 2 via the upper load transmission member 51 and the lower load transmission member 52.

[0065] The present disclosure is not limited to the above-described embodiment and may be modified as appropriate. For example, the upper load transmission member 51 may be provided across the entire width, i.e., length, of the upper frame 33. The lower load transmission member 52 may be provided across the entire width, i.e., length, of the lower frame 34. Only one of the upper load transmission member 51 and the lower load transmission member 52 may be provided. A load transmission member may be provided on the upper frame 43 of the outer shoji screen 4, facing the upper frame 21 in the indoor / outdoor direction, to transmit wind load between the upper frame 43 and the upper frame 21. A load transmission member may be provided on the lower frame 44 of the outer shoji screen 4, facing the lower frame 22 in the indoor / outdoor direction, to transmit wind load between the lower frame 44 and the lower frame 22. The frame 31 of the inner shoji screen 3 and the frame 41 of the outer shoji screen 4 may be assembled horizontally.

[0066] 26, the lower portion 221c of the rising portion 221a of the inner shoji lower rail 221 of the lower frame 22, with which the lower load transmission member 52 comes into contact, may be thickened in the indoor / outdoor direction.

The fixing protrusion 953 has an attachment portion 954, a pair of pull-out prevention pieces 955, 955, and a second pull-out prevention piece 956. The attachment portion 954 is attached to the outdoor surface of the fixing plate 952 and protrudes from the fixing plate 952 toward the outdoor side. The pair of first pull-out prevention pieces 955, 955 extend gradually from each side edge of the attachment portion 954 toward both sides in the width direction, diagonally toward the fixing plate 952. The pair of first pull-out prevention pieces 955, 955 are elastically deformable. The second pull-out prevention piece 956 protrudes downward from the lower edge of the attachment portion 954 and further bends toward the fixing plate 952. When the fixing protrusion 953 is inserted into the fixing hole 336a of the upper frame 33, the pair of first pull-out prevention pieces 955, 955 are pushed in the width direction and elastically deformed, and after being inserted into the fixing hole 336a, they restore their original shape inside the door end frame 35. This makes it difficult for the fixing protrusion 953 inserted into the fixing hole 336a to come off the door end frame 35. Safety caps similar to the safety cap 95 may also be provided at the lower end of the door end frame 35 of the inner shoji screen 3 and the upper and lower ends of the door end frame 45 of the outer shoji screen 4.
