Description

[Technical field]

[0001] The present disclosure relates to shoji screens and fittings. [Background technology]

[0002] A conventionally known structure for shoji doors is one in which a panel such as glass is fixed to a frame using a batten (see, for example, Patent Document 1). The batten is provided on either the indoor or outdoor side of the panel. A groove for mounting a frame is formed on either the indoor or outdoor side of the part of the frame where the panel is placed, and a panel support part is provided on the other side to hold down and support the panel pressed by the batten. The panel support part protrudes inward (the side where the panel is placed relative to the frame) when viewed from the indoor / outdoor direction so as to overlap with the edge of the panel in the indoor / outdoor direction.

[0003] In recent years, when attaching a handle to the frame for opening and closing a shoji screen, a structure has become known in which the handle is attached to the inset surface of the frame (the surface perpendicular to the inset surface) rather than to the inset surface of the frame (the surface parallel to the surface material of the shoji screen when closed). By attaching the handle to the inset surface of the frame, the width of the frame can be reduced when viewed from the inside and outside of the room, and the overlap with the surface material can be reduced. This improves the design of the fixture. If the surface material is glass, the glass area is increased, improving the view and improving insulation performance.

[0004] [Patent Document 1] JP 2016-113843 A Summary of the Invention [Problem to be solved by the invention]

[0005] To enable the handle attached to the visible surface to be opened and closed from the indoor side, the handle is attached to the visible surface of the frame on the indoor side of the panel. However, even if the handle is attached to the visible surface of the frame on the indoor side of the panel to reduce the overlap with the panel, if the edging is located on the outdoor side of the panel and the panel support part is provided on the indoor side of the panel, the panel support part will be positioned overlapping the indoor side of the panel, so the width of the frame cannot be reduced.

[0006] The present disclosure aims to provide a shoji screen and fittings that enable the width dimension of the frame to be reduced. [Means for solving the problem]

[0007] In order to achieve the above object, the shoji screen of the present disclosure comprises a frame provided on the peripheral edge of a panel, an inner edge that is disposed on the indoor side of the panel and presses the panel to the outdoor side, and a handle that is attached to the frame for opening and closing the panel, the frame comprising a panel groove in which the edge of the panel is disposed, a panel support portion that is disposed on the outdoor side of the panel groove and supports the panel that is pressed to the outdoor side by the inner edge, and a handle attachment portion that is located on the indoor side of the panel groove. An inner ledge attachment portion located on the outdoor side of the handle attachment portion and on the indoor side of the surface material, to which the inner ledge is attached; The handle is attached to the visible surface of the handle attachment portion on the indoor side of the panel. The end surface of the inner flange mounting portion on the side where the inner flange is mounted and the end surface of the handle mounting portion on the side where the handle is mounted are on the same plane. .

The third intermediate plate portion 67 and the fourth intermediate plate portion 68 are symmetrical to each other in the width direction.

[0047] The outdoor rib 69 is formed in a flat plate shape, extends from a widthwise intermediate portion of the outdoor plate portion 61 to the indoor 13 side with the plate surface parallel to the finding surface, and is connected to the first finding plate portion 63. Two outdoor ribs 69 are provided, and are arranged at intervals from each other in the width direction. The indoor rib 70 is formed in a flat plate shape, extends from a widthwise intermediate portion of the indoor plate portion 62 to the outdoor 14 side with the plate surface parallel to the finding surface, and is connected to the second finding plate portion 64. Four indoor ribs 70 are provided, and are arranged at intervals from each other in the width direction.

[0048] The upright 6 has a hollow upright portion 71 formed therein, surrounded by a first facing plate portion 63, a second facing plate portion 64, a first intermediate plate portion 65, and a second intermediate plate portion 66. In the hollow upright portion 71, a core material 72 is disposed.

[0049] The mullion 6 is formed with a first groove 731, a second groove 732, a third groove 733, and a fourth groove 734. The first groove 731 is surrounded by the exterior plate 61, the first facing plate 63, and the exterior rib 69, and opens to one side in the width direction. The second groove 732 is surrounded by the exterior plate 61, the first facing plate 63, and the exterior rib 69, and opens to the other side in the width direction. The third groove 733 is surrounded by the third intermediate plate 67, the indoor plate 62, and the interior rib 70, and opens to the exterior 14 side. The fourth groove 734 is surrounded by the fourth intermediate plate 68, the indoor plate 62, and the interior rib 70, and opens to the exterior 14 side.

[0050] When the opening is closed, the door frame 8 is positioned relative to the mullion 6 as follows: the interior board portion 82 and the second facing board portion 64 face each other, and the airtight material fitted into the third groove portion 733 comes into contact with the interior board portion 82. The fourth frame side board portion 834 and the first intermediate board portion 65 face each other in the width direction.

[0051] A FIXED window is arranged on the other side in the width direction of the mullion 6. The FIXED window's face material 222 is arranged inside the corner formed by the second intermediate plate portion 66 and the first sight plate portion 63. The FIXED window's face material 222 is pressed against the room 13 by the outer pressing edge 27 fitted into the second groove portion 732. The second sight plate portion 64 is arranged on the room 13 side of the FIXED window's face material 222, and abuts against the airtight material 28 fitted into the fourth groove portion 734.

[0052] 3 and 5, the upper frame 31, the lower frame 32 and the vertical frames 33, 34 are each provided with a groove 361 into which the outer batten 27 can be fitted, and a panel support portion 362 that supports the panel 222 pressed against the interior of the room 13 by the outer batten 27. For this reason, the entire outer periphery of the panel 222 of the FIX window is pressed against the panel support portion 362 by the outer batten 27.

[0053] Since the first shoji 21 has a structure in which the surface material 212 is pressed against the frame 211 by the inner pressing edge 24 and fixed, the surface material support part 96 that supports the surface material 212 pressed by the inner pressing edge 24 is arranged on the outside 14 side. Since the handle 25 is attached to the visible surface (the seventh surface material side plate part 847) of the handle attachment part 94, the width dimension of the handle attachment part 94 can be made smaller than when the handle 25 is attached to the visible surface. In this way, the surface material support part 96 is not arranged on the indoor 13 side of the surface material 212, and the width dimension of the handle attachment part 94 can be made smaller, so the width dimension of the frame 211 (door end frame 8) can be made smaller. As a result, the portion where the frame 211 overlaps with the surface material 212 on the indoor 13 side of the surface material 212 can be made smaller, and the design and view of the fitting 1 can be improved. By making the width dimension of the frame 211 smaller, the heat insulation of the fitting 1 can be improved.

[0054] The end of the inner edge mounting portion 97 of the frame 211 of the first shoji screen 21 facing the panel 212 and the end face of the handle mounting portion 94 facing the panel 212 are on the same plane. With this configuration, no step is created between the end of the inner edge mounting portion 97 facing the panel 212 and the end face of the handle mounting portion 94 facing the panel 212, making it possible to reduce the width dimension of the door end frame 8. The shape of the door end frame 8 can be simplified.

[0055] The first hollow portion 931 of the frame 211 of the first shoji screen 21 has a larger indoor / outdoor dimension than the indoor / outdoor dimension of the surface material groove portion 95. This configuration allows the core material 936 placed in the first hollow portion 931 to be made larger, and strength can be ensured even with a thin core material 936. Since the second groove portion 91 of the inner embossing attachment portion 97 of the frame 211 is on the indoor 13 side of the surface material 212, there is no need to form a groove portion for attaching the embossing to the portion of the frame 211 on the outdoor 14 side. This allows the first hollow portion to extend to the outdoor side, and the indoor / outdoor dimension of the first hollow portion 931 can be made larger than the indoor / outdoor dimension of the surface material groove portion 95.

[0056] The first hollow portion 931 of the frame 211 of the first shoji screen 21 can accommodate the core material 936, and can also accommodate the back plate 254 for fixing the friction stay 253 for opening and closing the first shoji screen 21. In other words, the hollow portion for installing the core material 936 and the hollow portion for installing the back plate 254 are the same hollow portion. Therefore, in the door end frame 8 and the hanging frame 215 where the back plate 254 is not installed, the space for installing the back plate 254 can also be used to install a large core material 936.

[0057] The fixture 1 is a continuous window consisting of a vertical sliding window and a fixed window arranged in series, and the face material 212 of the fixed window is fixed to the fixture frame 3 by an outer batten 27 arranged on the exterior 14 side of the face material 212. With this configuration, the face material 212 can be installed or replaced on the fixture frame 3 from the exterior 14 side.

[0058] The present disclosure is not limited to the above embodiment and can be modified as appropriate. For example, the end of the inner ridge mounting portion 97 of the frame 211 of the first shoji screen 21 on the surface material 212 side and the end face of the handle mounting portion 94 on the surface material 212 side are on the same plane. In contrast, the end of the inner ridge mounting portion 97 on the surface material 212 side and the end face of the handle mounting portion 94 on the surface material 212 side do not have to be on the same plane.

[0059] The first hollow portion 931 of the frame 211 of the first shoji screen 21 has a dimension in the indoor / outdoor direction that is larger than the dimension in the indoor / outdoor direction of the surface material groove portion 95. The first hollow portion 931 of the frame 211 of the first shoji screen 21 may have a dimension in the indoor / outdoor direction that is smaller than the dimension in the indoor / outdoor direction of the surface material groove portion 95.

[0060] The first hollow portion 931 of the frame 211 of the first shoji screen 21 can accommodate the core material 936 and the back panel 254. The frame 211 may be provided with a hollow portion for installing the core material 936 and a hollow portion for installing the back panel 254 separately.

[0061] The frame 211 of the first shoji screen 21 has a first hollow portion 931 surrounded by the exterior panel portion 81, the first rib 87, the third panel portion 843, the fourth panel portion 844, the fifth panel portion 845, the middle panel portion 85, the fourth frame side panel portion 834, the third frame side panel portion 833, and the second rib 88. Alternatively, as shown in Fig. 7, the frame 211 may have a third rib 89 connecting the corner portion between the second frame side panel portion 832 and the third frame side panel portion 833 and the corner portion between the second panel portion 842 and the third panel portion 843, and a first hollow portion 931B on the room 13 side of the third rib 89 and a fifth hollow portion 935 on the room 14 side of the third rib 89. Core material 936B is placed in first hollow portion 931B. By doing so, the heat insulating performance of frame 211 can be improved.

[0062] The fixture 1 is a continuous window consisting of a vertical sliding window and a fixed window arranged in series, and the face material 212 of the fixed window is fixed to the fixture frame 2 by an outer batten 27 arranged on the exterior 14 side of the face material 212. However, the fixture 1 does not have to be a continuous window. The fixture 1 is not limited to a vertical sliding window, and can be a horizontal sliding window, a casement window, or any other fixture that uses a handle to open and close the door like a sliding screen.
