[0009] One embodiment of the shoji screen of the present invention will be described with reference to the drawings. In this embodiment, as an example of a shoji screen according to the present invention, we will describe a shoji screen 3 provided in a fitting 1 for a vertically sliding window.

[0010] In the following explanation, when the joinery 1 is installed in a building or the like, the up-and-down direction is referred to as the up-and-down direction, the left-and-right direction as the left-and-right direction, and the depth direction, which is the direction between the interior and exterior of the building, as the depth direction.

[0011] As shown in Figures 1 to 3, the joinery 1 of this embodiment comprises a window frame 2 that is framed in a rectangular shape to form an opening, a sliding screen 3 installed inside the window frame 2, and a link mechanism (not shown) provided between the window frame 2 and the sliding screen 3. The sliding screen 3 is supported by a pivot shaft that is rotatable while moving along the vertical direction and horizontally (left and right direction), and is configured to be opened by pushing the handle 4 (Figure 3) on the sliding screen 3 outwards. That is, in Figure 3, the left side of the joinery 1 is the door edge side, and the right side is the hinge side.

[0012] The window frame 2 is framed in a rectangular shape with an upper frame 21, a lower frame 22, and vertical frames 23 positioned on the left and right sides. As shown in Figures 2 and 3, the upper frame 21, the lower frame 22, and the left and right vertical frames 23 are all connected by frame connecting members 21C, 22C, and 23C, with outdoor frame members 21A, 22A, and 23A located on the outdoor side and indoor frame members 21B, 22B, and 23B located on the indoor side. The outdoor frame members 21A, 22A, and 23A and the indoor frame members 21B, 22B, and 23B are extruded aluminum profiles, while the frame connecting members 21C, 22C, and 23C are made of synthetic resin.

[0013] The shoji screen 3 has a double-glazed glass 5 having three glass plates 5A, 5B, and 5C, and a frame 6 that serves as a frame for holding the double-glazed glass 5. The double-glazed glass 5 has three glass plates 5A, 5B, and 5C that are spaced apart from each other in the depth direction and joined together between the outer edges of each glass plate 5A, 5B, and 5C via a sealing spacer 5D. In the following description of the shoji screen 3, in the in-plane direction of the double-glazed glass 5 or the three glass plates 5A, 5B, and 5C, the outside of the frame 6 is referred to as the outer periphery side, and the inside of the frame 6 is referred to as the inner periphery side.

[0014] Of the three glass plates 5A, 5B, and 5C, the outer peripheral end surface 5E forming the outer peripheral end of the outermost glass plate 5A disposed on the outermost side is located on the outer peripheral side in the in-plane direction of the outermost glass plate 5A (the multilayer glass 5) with respect to the outer peripheral end surfaces 5F forming the outer peripheral ends of the indoor-side glass plates 5B and 5C disposed on the indoor side of the outermost glass plate 5A. That is, the outermost glass plate 5A has an extending portion 5G extending outward in the circumferential direction on all four sides beyond the outer peripheral end surfaces 5F of the indoor-side glass plates 5B and 5C.

[0015] Here, in the present embodiment, an example in which the multilayer glass 5 has two indoor-side glass plates 5B and 5C is described, but the number of indoor-side glass plates is not limited to two. For example, when the multilayer glass 5 is composed of two glass plates, the number of indoor-side glass plates is one, and when the multilayer glass 5 is composed of four or more glass plates, the number of indoor-side glass plates is three or more.

[0016] The frame 6 is formed by arranging an upper frame 7, a lower frame 8, and vertical frames 9 arranged on the left and right in a rectangular shape, and the left and right vertical frames 9 are fixed and framed by screws that enter in the left-right direction and are screwed into the upper frame 7 or the lower frame 8. As shown in FIGS. 4 to 6, each of the upper frame 7, the lower frame 8, and the left and right vertical frames 9 has an outer peripheral frame member 70, 80, 90 located on the outer peripheral side and an inner peripheral frame member 71, 81, 91 located on the inner peripheral side, which are connected by frame connecting members 72, 82, 92. The outer peripheral frame members 70, 80, 90 and the inner peripheral frame members 71, 81, 91 are aluminum extrusion profiles with the longitudinal direction as the extrusion direction, and the frame connecting members 72, 82, 92 are formed of synthetic resin.

[0017] The outer peripheral frame members 70, 80, 90 have a square tubular portion 70B, 80B, 90B forming a hollow portion 70A, 80A, 90A that penetrates in the longitudinal direction and has a rectangular cross-section, and an outer peripheral wall portion 70C, 80C, 90C that is connected to the square tubular portion 70B, 80B, 90B and extends indoors.

[0018] The rectangular tubular sections 70B, 80B, and 90B have a rectangular cross-sectional shape that is elongated in the depth direction, and the outer periphery wall sections 70C, 80C, and 90C are provided in the rectangular tubular sections 70B, 80B, and 90B, connected to the inner periphery edge of the indoor facing wall sections 70D, 80D, and 90D that form the indoor facing surface.

[0019] As shown in Figure 4, the upper frame 7 has a projection 70E that protrudes inward (downward) from the indoor visible wall portion 70D, and the outer wall portion 70C extends inward from the inner end of the projection 70E. On the inner side of the outer wall portion 70C, an inner frame material 71 is arranged at intervals in the in-plane direction (vertical direction) of the double-glazed glass 5, and the outdoor ends of the outer wall portion 70C and the inner frame material 71 and the indoor ends of the outer wall portion 70C and the inner frame material 71 are connected by a frame connecting material 72.

[0020] The protruding portion 70E connected to the outdoor end of the outer perimeter wall portion 70C, the outdoor frame connecting member 72, and the outdoor end of the inner perimeter frame member 71 form a flat surface 7A. The rectangular tubular portion 70B is located on the outer perimeter side of the outer perimeter wall portion 70C, and the portion on the outdoor side of the indoor surface wall portion 70D is located on the outdoor side of the surface 7A.

[0021] As shown in Figure 5, the lower frame 8 has a rectangular tubular portion 80B that faces the rectangular tubular portion 70B of the upper frame 7, and an outer perimeter wall portion 80C is provided at a position where the inner perimeter wall portion 80F facing the center of the frame body 6 extends inward from the indoor visible wall portion 80D. On the inner perimeter side of the outer perimeter wall portion 80C, inner perimeter frame material 81 is arranged with spacing in the in-plane direction (vertical direction) of the double-glazed glass 5, and the outdoor ends of the outer perimeter wall portion 80C and the inner perimeter frame material 81 and the indoor ends of the outer perimeter wall portion 80C and the inner perimeter frame material 81 are connected by frame connecting material 82.

[0022] The outer end of the outer wall portion 80C, the outer frame connecting member 82, and the outer end of the inner perimeter frame member 81 form a flat visible surface 8A. The rectangular tubular portion 80B is located on the outer side of the visible surface 8A, and the portion on the outer side of the indoor visible wall portion 80D is located on the outer side of the visible surface 8A.

[0023] As shown in Figure 6, the vertical frame 9 has a projection 90E that slightly protrudes inward (left or right) from the indoor visible wall portion 90D, and the outer wall portion 90C extends inward from the inner end of the projection 90E. On the inner side of the outer wall portion 90C, an inner frame material 91 is arranged at intervals in the in-plane direction (left-right direction) of the double-glazed glass 5, and the outdoor ends of the outer wall portion 90C and the inner frame material 91 and the indoor ends are connected by a frame connecting material 92.

[0024] The protruding portion 90E, which is the outdoor end of the outer peripheral wall portion 90C, the outdoor frame connecting member 92, and the outdoor end of the inner peripheral frame member 91 form a flat surface 9A. The rectangular tubular portion 90B is located on the outer peripheral side of the outer peripheral wall portion 90C, and the portion on the outdoor side of the indoor visible wall portion 90D is located on the outdoor side of the surface 9A.

[0025] The double-glazed glass 5 is installed with the indoor glass plates 5B and 5C positioned in the space surrounded by the rectangular tubular sections 70B, 80B, and 90B. Specifically, the outer peripheral end faces 5F of the indoor glass plates 5B and 5C face the inner peripheral wall sections 70F, 80F, and 90F of the frame 6 facing the center side in each of the rectangular tubular sections 70B, 80B, and 90B, with a gap in the in-plane direction, and the outer peripheral part of the indoor side of the glass plate 5C faces the respective facing surfaces 7A, 8A, and 9A, with a gap in the depth direction.

[0026] The double-glazed glass panes 5 are placed on the rectangular tubular portion 80B of the lower frame 8 via setting blocks 3A. The innermost glass pane 5C is joined to each of the facing surfaces 7A, 8A, and 9A with a backing material 3B interposed between them, and a waterproof coating material, so-called sealant 3C, which becomes rubbery and repels water when applied.

[0027] The outermost glass pane 5A of the double-glazed glass 5 has an extended portion 5G that faces the outdoor facing wall portions 70G, 80G, and 90G, which form the outdoor facing surface at each of the rectangular tubular portions 70B, 80B, and 90B, with a gap in the depth direction. The outermost glass pane 5A is fixed between the extended portion 5G and the outdoor facing wall portions 70G, 80G, and 90G with a backup material 3B interposed therebetween, and is fixed by a so-called structural sealant 3D for structurally bonding and fixing the members together.

[0028] In the sash 3, to which the double-glazed glass 5 is attached to the frame 6, the upper frame 7, lower frame 8, and left and right vertical frames 9 do not protrude outward from the outermost glass plate 5A. The outdoor visible wall portions 70G, 80G, and 90G that form the outdoor ends of the upper frame 7, lower frame 8, and left and right vertical frames 9 are located on the indoor side from the outermost glass plate 5A and face the extended portion 5G in the depth direction.

[0029] As shown in Figure 1, the vertical frame 9 located on the door edge side of the shoji screen 3 has regulating members 10 attached to both the upper and lower ends. The regulating member 10 attached to the upper end has the shape of the regulating member 10 attached to the lower end inverted vertically, so here we will explain using the regulating member 10 attached to the lower end as an example.

[0030] As shown in Figures 7 and 8, the regulating member 10 attached to the lower end has a vertical frame facing portion 10A as a fixing portion that is fixed facing the vertical frame 9, an indoor facing wall portion 10B that extends outward from the outdoor end of the vertical frame facing portion 10A and forms a visible surface, an outdoor facing wall portion 10C that is spaced apart and faces the outdoor side of the indoor facing wall portion 10B, a side connecting portion 10D that connects the door-side ends of the indoor facing wall portion 10B and the outdoor facing wall portion 10C, and a horizontal connecting portion 10E that connects the lower ends of the indoor facing wall portion 10B and the outdoor facing wall portion 10C (or the upper ends in the case of the upper regulating member).

[0031] The vertical frame opposite portion 10A is a flat plate that faces the frame wall portion 90H which forms the outer surface of the rectangular tubular portion 90B of the left vertical frame 9, and has an insertion hole 10F through which a screw 12 that is screwed into the frame wall portion 90H is inserted.

[0032] The gap between the indoor visible wall portion 10B and the outdoor visible wall portion 10C is formed to be slightly wider than the thickness of the outermost glass plate 5A. The regulating member 10 is attached to the vertical frame 9 by screwing the vertical frame opposite portion 10A to the frame visible wall portion 90H, with the lower corner on the door-side of the outermost glass plate 5A inserted between the indoor visible wall portion 10B and the outdoor visible wall portion 10C. At this time, the lower corner on the door-side of the outermost glass plate 5A is covered by the regulating member 10.

[0033] With the lower restricting member 10 attached to the vertical frame 9, the indoor visible wall portion 10B is in contact with or close to the indoor side surface of the extension portion 5G of the outermost glass plate 5A, the outdoor visible wall portion 10C is in contact with the outdoor side surface of the extension portion 5G of the outermost glass plate 5A, the side connecting portion 10D is in contact with or close to the outer peripheral end surface 5E on the door edge side of the outermost glass plate 5A, and the horizontal connecting portion 10E is in contact with or close to the lower outer peripheral end surface 5E of the outermost glass plate 5A.

[0034] Furthermore, when the upper regulating member 10 is attached to the vertical frame 9, the indoor visible wall portion 10B is in contact with or close to the indoor side surface of the extension portion 5G of the outermost glass plate 5A, the outdoor visible wall portion 10C is in contact with the outdoor side surface of the extension portion 5G of the outermost glass plate 5A, the side connecting portion 10D is in contact with or close to the left outer peripheral end surface 5E of the outermost glass plate 5A, and the horizontal connecting portion 10E is in contact with the upper outer peripheral end surface 5E which is the outer peripheral end of the outermost glass plate 5A. Here, the outdoor visible wall portion 10C corresponds to the outdoor facing portion that faces the outdoor side surface of the glass plate, and the side connecting portion 10D and the horizontal connecting portion 10E correspond to the outer peripheral end surface facing portions that face the outer peripheral end surface of the glass plate.

[0035] In this embodiment of the sliding door 3, a restricting member 10 is fixed to the frame 6 located on the indoor side of the double-glazed glass 5. The frame 6 has a side connecting portion 10D that faces the door edge side of the outermost glass plate 5A, whose indoor side is bonded to the frame. By restricting the in-plane movement of the outermost glass plate 5A, the in-plane movement of the double-glazed glass 5 is also restricted, making it possible to hold the double-glazed glass 5 in a more stable state.

[0036] Furthermore, since the horizontal connecting portion 10E, which faces the outer peripheral end surface 5E that is the lower surface of the outermost glass plate 5A, supports the double-glazed glass 5, it is possible to continue to hold the double-glazed glass 5 even if the adhesive strength of the adhesive layer bonding the double-glazed glass 5 decreases. Therefore, it is possible to provide a shoji screen 3 that can more reliably hold the double-glazed glass 5 bonded to the frame 6.

[0037] Furthermore, since the restricting member 10 fixed to the frame 6 has an outdoor facing wall portion 10C that faces the outdoor side of the outermost glass plate 5A, it is possible to restrict the movement of the double-glazed glass 5 towards the outdoors by also restricting the movement of the outermost glass plate 5A towards the outdoors. This makes it possible to hold the double-glazed glass 5 more securely.

[0038] Generally, when a sliding door that is supported at the hinge side and is rotatably mounted is pushed outwards to open the door, the door edge may tilt so that it is lower than the hinge side. In this case, if the glass plate, such as double-glazed glass, is fixed with adhesive, there is a risk that the glass plate may move towards the door edge in accordance with the tilt of the sliding door if the adhesive strength decreases. In this embodiment, the sliding door 3 has a restricting member 10 on the door edge side, so even if the adhesive strength decreases, it is possible to restrict the movement of the outermost glass plate 5A and the double-glazed glass 5 toward the door edge.

[0039] Furthermore, since the restricting member 10 covers the corner of the outermost glass plate 5A on the door-side, the corner of the outermost glass plate 5A on the door-side is not exposed when the sliding door 3 is opened. This prevents the user from coming into contact with the corner of the outermost glass plate 5A.

[0040] In the above embodiment, an example was described in which the restricting member 10 has an outdoor facing wall portion 10C that faces the outdoor side surface of the extension portion 5G of the outermost glass plate 5A. However, the outdoor facing wall portion 10C is not necessarily required. For example, as shown in Figure 9, even if the outdoor facing wall portion 10C is not provided, the in-plane movement of the double-glazed glass 5 can be restricted by restricting the in-plane movement of the outermost glass plate 5A with the side connecting portion 10D and the horizontal connecting portion 10E of the restricting member 10.

[0041] Furthermore, if the restricting member 10 does not have an outdoor visible wall portion 10C, it may be configured to be provided on the frame body 6 together with a holding member 11, which has an opposing wall portion 11A facing the outdoor side of the outermost glass plate 5A and a lower frame fixing portion 11B fixed to the lower frame, as shown in Figure 10. In this case, the holding member 11 can also restrict the movement of the outermost glass plate 5A and the double-glazed glass 5 toward the outdoor side, so the double-glazed glass 5 can be held more securely, similar to the restricting member 10 which has an outdoor visible wall portion 10C.

[0042] Furthermore, although the above embodiment describes an example in which the regulating member 10 is fixed to the vertical frame 9, it may also be fixed to the lower frame 8. For example, as shown in Figure 11, the horizontal connecting portion 10E may be extended beyond the vertical frame opposite portion 10A towards the suspension side, and the horizontal connecting portion 10E that protrudes beyond the vertical frame opposite portion 10A towards the suspension side may be extended to the same position as the indoor end of the vertical frame opposite portion 10A, so that the extended horizontal connecting portion 10E overlaps with the lower frame 8 in the vertical direction, and the horizontal connecting portion 10E may be screwed to the lower frame 8. In this case, if the regulating member 10 has an outdoor visible wall portion 10C, as shown in Figure 11A, the outdoor visible wall portion 10C may be extended beyond the vertical frame opposite portion 10A towards the suspension side, similar to the horizontal connecting portion 10E.

[0043] In the above embodiment, an example was described in which the frame body 6 is formed of aluminum outer frame members 70, 80, 90 and inner frame members 71, 81, 91 and synthetic resin frame connecting members 72, 82, 92, but it is not limited to this. For example, the outer frame members and inner frame members may be made of metals other than aluminum, and there may be no frame connecting members, and either the outer frame members or the inner frame members may be made of synthetic resin.

[0044] Furthermore, the frame may be made of metal, synthetic resin, or wood, and may be composed of a single upper frame, lower frame, and vertical frame that does not have frame connecting members and is not separated into outer and inner frame materials.

[0045] The above embodiments are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.

[0046] This embodiment discloses the shoji screens described in (1) to (6) below. (1) A sliding door comprising a glass plate, a frame positioned on the indoor side of the glass plate and to which the indoor side of the glass plate is bonded, and a restricting member fixed to the frame and having an outer edge facing portion that faces the outer edge surface of the glass plate, thereby restricting the movement of the glass plate.

[0047] In the shoji screen described in (1), a restricting member is fixed to the frame located on the indoor side of the glass plate, which has an outer edge facing portion that faces the outer edge of the glass plate to which the indoor side is bonded. This restricts the movement of the glass plate in the in-plane direction and makes it possible to hold the glass plate in a more stable state.

[0048] (2) In the sliding door described in (1), the regulating member is characterized in that it has an outdoor facing portion that faces the outdoor side surface of the glass plate.

[0049] In the shoji screen described in (2), the restricting member fixed to the frame has an outdoor-facing portion that faces the outdoor-facing surface of the glass plate, so that the movement of the glass plate toward the outside can also be restricted. This makes it possible to hold the glass plate more securely.

[0050] (3) In the sliding door described in (1) or (2), the portion of the regulating member that is positioned below the glass plate and faces the outer peripheral end face is characterized in that it faces the outer peripheral end face that forms the lower surface of the glass plate.

[0051] In the shoji screen described in (3), the outer peripheral end face of the regulating member positioned below the glass plate faces the outer peripheral end face that forms the lower surface of the glass plate, so that the glass plate can be supported by the outer peripheral end face. Therefore, even if the adhesive strength of the adhesive layer bonding the glass plate decreases, the glass plate can still be supported, making it possible to provide a shoji screen that can more reliably support the glass plate bonded to the frame.

[0052] (4) A sliding door as described in any of (1) to (3), characterized in that the hinge side is rotatably supported and can be opened and closed, and the regulating member is provided on the door edge side.

[0053] The shoji screen described in (4) is supported at the hinge side so that it can be opened and closed, which may cause the door edge to tilt so that it is lower than the hinge side, and if the adhesive strength decreases, the glass panel may move toward the door edge. This shoji screen has a regulating member provided on the door edge side, so even if the adhesive strength decreases, it is possible to restrict the movement of the glass panel toward the door edge.

[0054] (5) In the shoji screen described in (4), the regulating member is characterized in that it covers the corner of the glass plate.

[0055] In the shoji screen described in (5), the regulating member covers the corner of the glass plate on the door-side, so that the corner of the glass plate on the door-side is not exposed when the shoji screen is opened. This prevents the user from coming into contact with the corner of the glass plate.

[0056] (6) In a shoji screen as described in any of (1) to (4), the glass plate is characterized in that it is bonded with a structural sealant.

[0057] In the shoji screen described in (6), the glass plate is bonded with structural sealant, and since the regulating member is provided while the glass plate is held in place by the structural sealant, it is possible to hold the glass plate more securely. [Explanation of Symbols]
