Description

[Technical Field]

[0001] The present disclosure relates to a shoji screen. [Background technology]

[0002] Conventionally, shoji screens such as sashes have been provided with a ridge for attaching a surface material such as a glass panel to the frame (see, for example, Patent Document 1). In shoji screens such as aluminum sashes and aluminum-resin composite sashes, the ridge is provided on the interior side of the surface material. Therefore, when assembling the surface material into the frame installed in the building frame, the surface material is transported from the interior side to the installation location and fitted into the frame from the interior side.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-132340 Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, when installing large-opening sashes with good views on the upper floors of a super-high-rise building, the glass panels (surface materials) become large and heavy. If the large-opening sashes have high airtightness and pressure resistance, the glass panels become even heavier. This can make it difficult to transport large and heavy glass panels from the interior of the building to the installation location.

[0005] The present disclosure aims to provide a shoji screen in which face materials can be fitted from the outside of the room. [Means for solving the problem]

[0006] In order to achieve the above object, the shoji screen according to the present disclosure has a frame that slides inside the frame, a frame, a face material that fits into the frame, a first spacer that is provided between the frame and the interior surface of the edge of the face material, a second spacer that is provided in contact with the exterior surface of the edge of the face material, and a push edge that is attached to the exterior side of the frame and presses the second spacer against the face material from the exterior side, the first spacer being attached to a protrusion that is provided on the frame, and the second spacer being engaged with a protrusion that is provided on the push edge. The frame has an inner peripheral end surface located on the outside of the room and facing inward in the viewing direction, and the ledge has a surface that is in surface contact with the inner peripheral end surface. .

[0069] As shown in FIG. 1 , a fixed shoji screen 3 is installed on the first vertical frame 24 and mullion 9 without using a batten 34. The fixed shoji screen 3 is positioned on the other widthwise side of the vertical frame inner panel 242 of the first vertical frame 24, between the vertical frame room-side panel 244 and the first protruding piece 246. The first spacer 32 is attached to the protruding portion 244a of 244. The double-glazed glass 31 is installed in contact with the exterior 14 side of the first spacer 32. The second spacer 33 is installed in contact with the exterior 14 side of the double-glazed glass 31. The second spacer 33 is in contact with the surface of the first protruding piece 246 facing the room 13. The first protruding piece 246 of the first vertical frame 24 has a protruding portion 246b for attaching the second spacer 33. The second spacer 33 is pressed against the interior 13 side by the first protruding piece 246 of the first vertical frame 24.

[0070] The FIX shoji screen 3 is positioned on one widthwise side of the third mullion projection panel 93 of the mullion, and between the mullion exterior panel 94 and the mullion facing panel 96. The first spacer 32 is attached to the convex portion of the mullion facing panel 96. The double-glazed glass 31 is installed in contact with the exterior 14 side of the first spacer 32. The second spacer 33 is installed in contact with the exterior 14 side of the double-glazed glass 31. The second spacer 33 is in contact with the surface of the mullion exterior panel 94 facing the room 13. The mullion exterior panel 94 has a convex portion 942 formed thereon for attaching the second spacer 33. The second spacer 33 is pressed against the room 13 side by the mullion exterior panel 94.

[0071] The single sliding shoji screen 4 according to the above embodiment has an outer pressing edge structure in which the pressing edge 44 is attached to the exterior 14 side of the frame 7, and the second spacer 43 is pressed against the double glazing 41 from the exterior 14 side. Therefore, when installing the single sliding shoji screen 4, the double glazing 41 can be fitted into the frame 7 from the exterior 14 side. This means that, for example, when installing a large fitting 1 on a high floor of a high-rise building, the double glazing 41 can be transported from outside the room, making transportation easier than when transporting it from inside the room 13.

[0072] In the single sliding shoji screen 4 according to the above embodiment, the first spacer 42 is attached to the protrusions 714a, 725a, and 743a of the frame body 7. This ensures that the first spacer 42 is securely attached to the frame body 7, allowing the frame body 7 to stably support the double-glazed glass 41. Similarly, in the FIX shoji screen 3, the first spacer 32 is attached to the protrusions 236c, 244c, and 961 of the frame body 2. This ensures that the first spacer 32 is securely attached to the frame body 2, allowing the frame body 2 to stably support the double-glazed glass 31.

[0073] In the single sliding shoji screen 4 according to the above embodiment, the ledge 44 is attached to the exterior side of the upper frame 71, the lower frame 72, and the second vertical frame 74. This allows the double glazing 41 to be easily fitted into the frame 7 from the exterior side 14.

[0074] In the single sliding shoji screen 4 according to the above embodiment, the lower frame 72 is provided with the first hole 723b, the second hole 722a, and the third hole 721c, which serve as drainage holes. As a result, even if rainwater gets in between the ledge 44 and the second spacer 43, the rainwater flows down and is discharged to the outside of the single sliding shoji screen 4 through the first hole 723b, the second hole 722a, and the third hole 721c, preventing rainwater from accumulating inside the single sliding shoji screen 4.

[0075] The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit thereof. For example, in the above-described embodiment, a ledge 44 is provided on the exterior side 14 of the frame 7 of the single sliding shoji screen 4. The fixed shoji screen 3 may also be configured so that a ledge is provided on the exterior side of the frame, allowing the double-glazed glass to be attached to the frame from the exterior side.

[0076] In the above embodiment, the first hole 723b, the second hole 722a, and the third hole 721c, which serve as drainage holes, are provided in the bottom frame 72. The drainage holes provided in the bottom frame 72 may have a configuration other than the first hole 723b, the second hole 722a, and the third hole 721c. The bottom frame 72 does not necessarily have to have drainage holes.

[0077] In the above embodiment, the surface material provided inside the frame 7 is double glazing 41, but it may also be a glass panel other than double glazing 41 or a surface material other than glass. In the above embodiment, the bezel 44 is attached to the exterior sides of the upper frame 71, the lower frame 72, and the second vertical frame 74. In contrast to this, as long as the surface material can be attached to the frame 7 from the exterior side, the bezel 44 may be attached to the exterior sides of all of the upper frame 71, the lower frame 72, the first vertical frame 73, and the second vertical frame 74, or the bezel 44 may be attached to the exterior side of any of the upper frame 71, the lower frame 72, the first vertical frame 73, and the second vertical frame 74.
