Description

Technical Field

[0001] The present disclosure relates to multilayer glass and fittings.

Background Art

[0002] Conventionally, from the viewpoint of improving heat insulation and sound insulation, multilayer glass has been used as a glass window disposed in an opening of a building. The multilayer glass has, for example, at least two glass plates and a spacer. The spacer is disposed at a peripheral portion between the two glass plates and separates the two glass plates.

[0003] When manufacturing fittings such as sliding windows using multilayer glass, it is common to manufacture the fittings by fitting the multilayer glass into a frame formed in a rectangular shape. Thereby, sufficient strength as a fitting can be obtained. On the other hand, as a technique for imparting shape retention and long-term durability to the multilayer glass itself, a technique of disposing a resin spacer and a metal spacer in addition to a conventional spacer in a gap between the glass plates has been disclosed (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] From the viewpoint of improving design properties, it is preferable if the strength of the multilayer glass can be improved and a fitting can be configured without having a frame. However, in order to achieve the above object, when simply disposing a resin spacer as disclosed in Patent Document 1, sufficient strength of the fitting cannot be obtained. On the other hand, when disposing a metal spacer, there is a problem that the heat insulation of the fitting is deteriorated.

[0006] This disclosure is made in view of the above, and aims to provide double-glazed glass that has the strength to construct a door without a frame and that can ensure thermal insulation. [Means for solving the problem]

[0007] This disclosure relates to a double-glazed glass comprising at least two glass plates arranged with spacers in between, the double-glazed glass comprising a reinforcing member made of carbon fiber reinforced plastic and disposed at the end of the double-glazed glass in the visible direction, wherein the reinforcing member has a visible surface reinforcing portion disposed along the visible surface on the outside in the depth direction at the end of the double-glazed glass in the visible direction, and a depth surface reinforcing portion formed continuously with the visible surface reinforcing portion and disposed along the depth surface at the end of the double-glazed glass in the visible direction.

[0009] The panoramic window 1 as a building component of the first embodiment will be described below with reference to the drawings. As shown in Figure 1, the panoramic window 1 comprises a frame 10 and a parallel moving panel 20, a sliding moving panel 30, and a fixed panel 40 arranged within the frame 10. The parallel moving panel 20, the sliding moving panel 30, and the fixed panel 40 each constitute double-glazed glass as described in this disclosure. In this embodiment, the parallel moving panel 20 (sash), the sliding moving panel 30 (sash), and the fixed panel 40 (sash) are each constructed using double-glazed glass.

[0010] In this specification, "face direction" refers to the surface direction of the parallel moving panel body 20, sliding moving panel body 30, and fixed panel body 40 housed in the frame 10 of the joinery, and "depth direction" refers to the interior-exterior direction (i.e., the depth direction). Furthermore, in the face direction, the left and right directions in Figure 1 are referred to as the left-right direction X. One side (left) of the left-right direction X in Figure 1 is referred to as the X1 side, and the other side (right) of the left-right direction X is referred to as the X2 side. Furthermore, the interior-exterior direction in Figures 2 to 5 is referred to as the depth direction Y. The far side in the depth direction Y is referred to as the exterior side Y1, and the near side is referred to as the interior side Y2. "Face surface" refers to the respective surfaces of the panoramic window 1 facing the exterior side Y1 and the interior side Y2, and "depth surface" refers to the surface of the panoramic window 1 extending in the depth direction Y (interior-exterior direction).

[0011] As shown in Figure 1, the frame 10 is constructed by framing an upper frame 11, a lower frame 12, and a pair of vertical frames 13 and 14 in a rectangular shape. The upper frame 11, the lower frame 12, and the pair of vertical frames 13 and 14 are formed, for example, by extruding aluminum. Parallel moving panel bodies 20, sliding moving panel bodies 30, and fixed panel bodies 40 are arranged within the frame 10.

[0012] As shown in Figures 2 to 4, the FIX panel 40 is fixed to the X2 side in the left-right direction X within the frame 10. The parallel moving panel 20 and the sliding panel 30 are driven by a drive unit (not shown) on the X1 side in the left-right direction X from the FIX panel 40 within the frame 10, and are movable to a closed position (see Figures 1 and 2), an intermediate position (see Figure 3), and an open position (see Figure 4).

[0013] When the panoramic window 1 is in the closed position, as shown in Figure 2, the parallel moving panel 20, the sliding panel 30, and the fixed panel 40 are arranged in a straight line within the frame 10, from the X1 side to the X2 side in the left-right direction X.

[0014] When the panoramic window 1 is in the closed position, the parallel moving panel body 20 and the sliding moving panel body 30 are positioned with their facing surfaces of the reinforcing members 25 and 35 (described later) at their outer ends in the left-right direction X at the joint 51. The sliding moving panel body 30 and the fixed panel body 40 are positioned with their facing surfaces of the reinforcing members 35 and 45 (described later) at their outer ends in the left-right direction X at the joint 52.

[0015] To move the panoramic window 1 from the closed position (see Figures 1 and 2) to the open position (see Figure 4), the parallel moving panel 20 is moved from the closed position shown in Figure 2 to the interior side Y2 in the depth direction Y, thereby moving it to the intermediate position shown in Figure 3. From the intermediate position shown in Figure 3, the sliding moving panel 30 is moved to the X1 side in the left-right direction X in the facing direction, thereby moving it to the open position shown in Figure 4.

[0016] When moving the panoramic window 1 from the open position (see Fig. 4) to the closed position (see Figs. 1 and 2), starting from the open position shown in Fig. 4, the slide moving panel body 30 is moved to the X2 side in the left - right direction X in the viewing direction to move to the intermediate position shown in Fig. 3. Then, starting from the intermediate position shown in Fig. 3, the parallel moving panel body 20 is moved to the outdoor side Y1 in the viewing direction Y, so that it can be moved to the open position shown in Fig. 2.

[0017] Next, the details of the configurations of the parallel moving panel body 20, the slide moving panel body 30, and the FIX panel body 40 will be described. The parallel moving panel body 20, the slide moving panel body 30, and the FIX panel body 40 constitute the multi - layer glass of the present disclosure.

[0018] As shown in Figs. 2 to 4, the parallel moving panel body 20, the slide moving panel body 30, and the FIX panel body 40 are each composed of three glass plates (outdoor - side glass plates 21, 31, 41, intermediate glass plates 22, 32, 42, indoor - side glass plates 23, 33, 43), spacers 24, 34, 44, a pair of reinforcing members 25, 35, 45, and airtight materials 28, 38, 48, which form a multi - layer glass.

[0019] The outdoor - side glass plates 21, 31, 41, the intermediate glass plates 22, 32, 42, and the indoor - side glass plates 23, 33, 43 are each formed in a rectangular shape. The outdoor - side glass plates 21, 31, 41, the intermediate glass plates 22, 32, 42, and the indoor - side glass plates 23, 33, 43 are laminated via air layers and arranged in this order in the viewing direction Y from the outdoor side Y1 to the indoor side Y2.

[0020] Spacers 24, 34, and 44 are placed between each of the three glass plates (outdoor glass plates 21, 31, 41, intermediate glass plates 22, 32, 42, and indoor glass plates 23, 33, 43) at the periphery of both ends, the upper end, and the lower end of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40 in the left-right direction X. As a result, the outdoor glass plates 21, 31, 41, intermediate glass plates 22, 32, 42, and indoor glass plates 23, 33, 43 are spaced apart by the spacers 24, 34, and 44, respectively. Note that the upper and lower ends of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40 are not shown in the illustration.

[0021] Spacers 24, 34, and 44 are formed as elongated units that extend along the respective vertical and horizontal sides at both ends, the upper end, and the lower end of the parallel moving panel body 20, the sliding panel body 30, and the fixed panel body 40 in the left-right direction X, respectively.

[0022] The exterior glass plates 21, 31, 41, the intermediate glass plates 22, 32, 42, and the interior glass plates 23, 33, 43 are not particularly limited in material and can be made of float glass, tempered glass, etc., manufactured by the float process. Laminated glass, patterned glass, wired glass, etc., may also be used. In this embodiment, the number of glass plates in the double-glazed glass (parallel moving panel body 20, slide moving panel body 30, FIX panel body 40) is three, but it is not limited to this and can be two or more.

[0023] As shown in Figures 2 to 4, the reinforcing members 25, 35, and 45 are attached to both ends of the outer side in the left-right direction X of the outdoor glass plates 21, 31, and 41 and the indoor glass plates 23, 33, and 43, respectively. As shown in Figures 2 to 4, the reinforcing members 25, 35, and 45 are positioned at both ends of the outdoor glass plates 21, 31, and 41 and the indoor glass plates 23, 33, and 43 in the left-right direction X, further outward in the left-right direction X than the spacers 24, 34, and 44. In this embodiment, although not shown, the reinforcing members are not provided at the upper and lower ends of the outdoor glass plates 21, 31, and 41 and the indoor glass plates 23, 33, and 43.

[0024] As shown in Figure 1, the pair of reinforcing members 25, 35, and 45 each have width and extend vertically (up and down) at both ends in the left and right directions of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40.

[0025] As shown in Figure 5, the reinforcing members 25, 35, and 45 are formed in a U-shape in cross-section, opening inward in the left-right direction X (lateral direction) when cut along the left-right direction X. The reinforcing members 25, 35, and 45 are formed in a continuous U-shape in cross-section, consisting of outdoor surface reinforcing parts 251, 351, and 451 (one-side surface reinforcing part, surface reinforcing part) arranged along the outer surface of the outdoor side Y1 of the outdoor glass plates 21, 31, and 41, surface reinforcing parts 252, 352, and 452 (surface reinforcing parts) arranged along the outer surface of the parallel moving panel body 20, sliding moving panel body 30, and FIX panel body 40 in the left-right direction X, and indoor surface reinforcing parts 253, 353, and 453 (other-side surface reinforcing part, surface reinforcing part) arranged along the outer surface of the indoor side Y2 of the indoor glass plates 23, 33, and 43.

[0026] The outdoor surface reinforcement parts 251, 351, and 451 of the outdoor side Y1 are positioned along the surface on the outside of the outdoor side Y1 of the parallel moving panel body 20, the sliding moving panel body 30, and the FIX panel body 40 at both ends in the left-right direction, and extend for a predetermined length in the left-right direction X. The outdoor surface reinforcement parts 251, 351, and 451 are fixed to the outdoor side Y1 (outside) surface of the outdoor glass plates 21, 31, and 41 with adhesive A. Since the adhesive A can be covered by the outdoor surface reinforcement parts 251, 351, and 451 of the reinforcing members 25, 35, and 45, the adhesive A can be protected from ultraviolet rays and its deterioration can be reduced.

[0027] The front surface reinforcement sections 252, 352, and 452 are formed continuously with the outer ends of the exterior surface reinforcement sections 251, 351, and 451 in the left-right direction X. The front surface reinforcement sections 252, 352, and 452 are arranged along the front surface on the outside in the left-right direction X of each of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40, and extend in the front direction Y from the outer ends of the exterior surface reinforcement sections 251, 351, and 451 in the left-right direction X for a length in the front direction Y of each of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40.

[0028] The indoor surface reinforcement portions 253, 353, and 453 of the indoor side Y2 are formed continuously with the ends of the interior surface reinforcement portions 252, 352, and 452 on the indoor side Y2. The indoor surface reinforcement portions 253, 353, and 453 of the indoor side Y2 are positioned along the surface on the outside of the indoor side Y2 at both the left and right ends of the parallel moving panel body 20, the sliding moving panel body 30, and the FIX panel body 40, and extend a predetermined length in the left and right direction X from the ends of the interior side Y2 of the interior surface reinforcement portions 252, 352, and 452 toward the inside in the left and right direction X. The indoor surface reinforcement portions 253, 353, and 453 are fixed to the indoor side Y2 (outside) surface of the indoor side glass plate 23, 33, and 43 with adhesive A. Since adhesive A can be covered by the reinforcing parts 253, 353, and 453 on the indoor side of the reinforcing members 25, 35, and 45, adhesive A can be protected from ultraviolet rays and its deterioration can be reduced.

[0029] As shown in Figure 5, in the reinforcing members 25, 35, and 45, the thickness T2 in the left-right direction X of the facing surface reinforcing parts 252, 352, and 452 is greater than the thickness T1 in the facing direction Y of the outdoor facing surface reinforcing parts 251, 351, and 451 located on the facing surface of the outdoor side Y1, and greater than the thickness T3 in the facing direction Y of the indoor facing surface reinforcing parts 253, 353, and 453 located on the facing surface of the indoor side Y2.

[0030] The reinforcing members 25, 35, and 45 suppress the deflection of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40, thereby ensuring strength. The reinforcing members 25, 35, and 45 are made of carbon fiber-reinforced plastics (CFRP). This makes it possible to construct a building component without a frame for the double-glazed glass (parallel moving panel body 20, sliding moving panel body 30, fixed panel body 40), while also ensuring thermal insulation. The carbon fiber-reinforced plastics that make up the reinforcing members 25, 35, and 45 are made by bundling multiple fibers that extend in a direction intersecting the width direction of the reinforcing members 25, 35, and 45 and fixing them with resin. The carbon fiber-reinforced plastics are formed by impregnating multiple bundles of fibers that extend in a direction intersecting the width direction of the reinforcing members 25, 35, and 45 with a resin such as a thermosetting resin or a thermoplastic resin and allowing it to harden. Furthermore, the direction in which the multiple fibers constituting the carbon fiber reinforced plastic extend does not have to coincide with the longitudinal direction of the reinforcing members 25, 35, and 45. Also, the multiple fibers constituting the carbon fiber reinforced plastic do not have to extend from end to end in the longitudinal direction of the reinforcing members 25, 35, and 45.

[0031] The carbon fiber reinforced plastics constituting the reinforcing members 25, 35, and 45 have an elastic strength greater than that of a glass plate. In this specification, elastic strength refers to Young's modulus, and the Young's modulus of a glass plate is approximately 71600 MPa. The Young's modulus can be measured in accordance with the general rules specified in JIS K 7161, in accordance with either JIS K 7164 (Isotropic and Orthotropic Anisotropic Fiber Reinforced Plastics) or JIS K 7165 (Unidirectional Fiber Reinforced Plastic Composite Materials).

[0032] As a result, the double-glazed structure of the parallel moving panel 20, the sliding moving panel 30, and the fixed panel 40 has a monocoque structure in which multiple glass plates and reinforcing members 25, 35, and 45 are integrated, thus achieving a higher strength than simply adding up the strengths of each member. In other words, while the glass strength is usually maintained by a frame (not shown) used at the glass edge, by using reinforcing members 25, 35, and 45 made of carbon fiber reinforced plastic instead of a frame, it is possible to ensure high strength without a frame while keeping the thickness in the depth direction Y down.

[0033] As shown in Figure 5, in the parallel moving panel 20, the sliding panel 30, and the fixed panel 40, spacers 24, 34, and 44 are placed between each of the three glass plates (outside glass plates 21, 31, 41, intermediate glass plates 22, 32, 42, and inside glass plates 23, 33, 43), and the reinforcing members 25, 35, and 45 are attached to both ends in the left-right direction X of the parallel moving panel 20, the sliding panel 30, and the fixed panel 40.

[0034] In this embodiment, the spacers 24, 34, and 44 are elastic bodies. Because the spacers 24, 34, and 44 are elastic bodies, when installing the reinforcing members 25, 35, and 45 on the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40, as shown in Figure 6, for example, in the case of the parallel moving panel body 20, the spacers 24 are placed between each of the three glass plates (outer glass plate 21, intermediate glass plate 22, and inner glass plate 23), and the parallel moving panel body 20 is compressed in the depth direction (see the upper and middle diagrams of Figure 6), allowing the reinforcing members 25 to be inserted along the width direction (see the middle and lower diagrams of Figure 6), making installation easier in manufacturing. In particular, the manufacturing benefits are significant for the reinforcing members 25, 35, and 45, which have a U-shaped cross-section as described in this embodiment. Examples of elastic bodies include styrene-based thermoplastic elastomers, resins with a desiccant added to butyl, and resins with a desiccant added to the bead of EPDM silicone.

[0035] As shown in Figure 2, when the panoramic window 1 is in the closed position, the contact material 13a attached to the indoor Y2 surface of the outdoor portion of the vertical frame 13, which is located on the outdoor Y1 side, contacts the outdoor Y1 surface of the reinforcing member 25 located on the X1 side of the parallel moving panel body 20. The contact material 13a is made of soft resin.

[0036] Furthermore, the abutment material 14a attached to the indoor Y2 surface of the outdoor portion of the vertical frame 14, which is positioned on the outdoor Y1 side, contacts the outdoor Y1 surface of the reinforcing member 45 positioned on the X2 side of the FIX panel body 40. The abutment material 14b attached to the outdoor Y1 surface of the indoor portion of the vertical frame 14, which is positioned on the indoor Y2 side, contacts the indoor Y2 surface of the reinforcing member 45 positioned on the X2 side of the FIX panel body 40. The abutment materials 14a and 14b are made of soft resin and, by contacting the outdoor Y1 surface and the indoor Y2 surface of the reinforcing member 45 positioned on the X2 side of the FIX panel body 40, they can follow the deformation of the FIX panel body 40 and act as a cushion.

[0037] As shown in Figure 2, a sheet-like airtight material 5 is placed in the recessed portion of each of the pair of vertical frames 13 and 14. The structure around the sheet-like airtight material 5 will now be described. The structure around the sheet-like airtight material 5 placed in the vertical frames 13 and 14 is symmetrical. Therefore, in this embodiment, the structure around the sheet-like airtight material 5 placed in the vertical frame 14 on the X2 side will be described.

[0038] As shown in Figure 7, the sheet-like airtight material 5 is formed extending in the depth direction Y and has a straight portion 531 extending in the depth direction Y on the outdoor side Y1, an inclined portion 532 connected to the indoor side Y2 end of the straight portion 531 and extending inclined with respect to the depth direction Y on the indoor side Y2, an outdoor side end projection 533 formed on the outer circumference of the end on the outdoor side Y1, and an indoor side end projection 534 formed on the outer circumference of the end on the indoor side Y2.

[0039] The sheet-like airtight seal 5 is made of a soft resin and, as shown in Figure 7, contacts the reinforcing member 45 to improve airtightness between the reinforcing member 45 and the vertical frame 14. The outdoor end projection 533 and the indoor end projection 534 of the sheet-like airtight seal 5 are fixed to both ends in the depth direction of a long plate-like member 61 made of aluminum. The plate-like member 61 located on the outer circumference side of the sheet-like airtight seal 5 is attached to the sheet-fixed member 62 with fixing members such as screws 61a. This sheet-fixed member 62 further has an opposing member 63 on its outer circumference side, and the sheet-fixed member 62 and the opposing member 63 are screwed together with screws 63a. The tension of the sheet-like airtight seal 5 can be adjusted by tightening or loosening these screws 63a.

[0040] Furthermore, the plate-shaped member 61 has a bendable piece 611 that is bent outward at the end on the outdoor side Y1 in the depth direction, and a resin member 64 is installed at the outer end of the bendable piece 611. This resin member 64 is in contact with a protruding portion 141 that protrudes inward at the insertion portion of the vertical frame 14. The protruding portion 141 has a protruding piece 141a that protrudes from the X1 side surface of the insertion portion of the vertical frame 14 towards X1 in the left-right direction X, and an extending portion 141b that extends from a portion of the protruding piece 141a in the X direction toward the indoor side Y2. The extending portion 141b is fixed to the outdoor side Y1 portion of the opposing member 63 by a screw 63a.

[0041] By using the sheet-like airtight material 5 in this way, even if the FIX panel body 40 warps in the height direction or width direction (depth direction Y) due to wind pressure or the like, the contact area between the sheet-like airtight material 5 and the reinforcing member 45 can be secured, thus maintaining airtightness. This is particularly effective when using large FIX panel bodies 40, as the warping of the FIX panel body 40 will also be greater.

[0042] As shown in Figure 5, the airtight materials 28, 38, and 48 are attached to the ends of the joints 51 and 52 sides of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40, respectively. The airtight materials 28, 38, and 48 are formed in a substantially L-shape and protrude outward from the ends in the left-right direction X of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40. In this embodiment, the airtight material 28 of the parallel moving panel body 20 is attached to the outer surface of the X2 side end of the parallel moving panel body 20 in the left-right direction X. The airtight material 38 of the sliding moving panel body 30 is attached to the outer surface of the X1 side end of the sliding moving panel body 30 in the left-right direction X. The airtight material 48 of the fixed panel body 40 is attached to the outer surface of the X1 side end of the fixed panel body 40 in the left-right direction X.

[0043] The airtight seals 28, 38, and 48 each have base portions 281, 381, and 481 connected to the outer surface of the reinforcing members 25, 35, and 45 in the left-right direction X, and extension portions 282, 382, ​​and 482 extending from the base portions 281, 381, and 481 opposite to the reinforcing members 25, 35, and 45 to the outdoor side Y1 or the indoor side Y2.

[0044] In this embodiment, the airtight seal 28 provided at the end of the parallel moving panel body 20 on the joint portion 51 side has a base portion 281 attached to the interior side Y2 of the interior surface reinforcement portion 252 of the reinforcing member 25, and an extension portion 282 extending from the portion of the base portion 281 opposite to the reinforcing member 25 to the exterior side Y1.

[0045] The pair of airtight seals 38 provided at the ends of the sliding panel body 30 on the joint portions 51 and 52 sides have a base portion 381 attached to the front surface of the front surface reinforcing portion 352 of each of the pair of reinforcing members 35, closer to the outdoor side Y1, and an extension portion 382 extending from the part of the base portion 381 opposite to the reinforcing member 35 toward the indoor side Y2.

[0046] The airtight seal 48, provided at the end of the FIX panel body 40 on the joint portion 52 side, has a base portion 481 attached to the reinforcing portion 452 of the reinforcing member 45 at a position closer to the indoor side Y2, and an extension portion 482 extending from the portion of the base portion 481 opposite to the reinforcing member 45 toward the outdoor side Y1.

[0047] As shown in Figure 2, at the joint 51 of the parallel moving panel 20 and the sliding panel 30, when the parallel moving panel 20 moves from the indoor side Y2 to the outdoor side Y1 from the state shown in Figure 3, the airtight materials 28 and 38 come into contact with each other, with the tip 282a of the extended portion 282 of the airtight material 28 of the parallel moving panel 20 pressing against the tip 382a of the extended portion 382 of the airtight material 38 of the sliding panel 30. This ensures airtightness between the parallel moving panel 20 and the sliding panel 30 in the closed position shown in Figure 2.

[0048] Furthermore, as shown in Figure 3, at the joint 52 of the sliding panel 30 and the fixed panel 40, when the sliding panel 30 moves from the X1 side to the X2 side in the left-right direction X from the state shown in Figure 4, the airtight materials 38 and 48 come into contact with the tip 382a of the extended portion 382 of the airtight material 38 of the sliding panel 30, which is pressed against the tip 482a of the extended portion 482 of the airtight material 48 of the fixed panel 40. This ensures airtightness between the sliding panel 30 and the fixed panel 40 at the positions shown in Figures 2 and 3.

[0049] By forming the airtight materials 28, 38, and 48 in a roughly L-shape, even if the movement directions of the sliding panel body 30 and the fixed panel body 40 differ, such as when they move in the left-right direction X or in the depth direction Y, the tips of the extended portions 282, 382, ​​and 482 of the airtight materials 28, 38, and 48 are pressed against each other at the joint portions 51 and 52, thereby ensuring airtightness. The airtight materials 28, 38, and 48 can be standardized even if the movement directions of the sliding panel body 30 and the fixed panel body 40 are different, thereby reducing manufacturing costs.

[0050] In this embodiment, the airtight materials 28, 38, and 48 are formed in a roughly L-shape, but are not limited to this. For example, as shown in the modified form in Figure 8, the airtight materials 29, 39, and 49 may be formed in a roughly right-angled triangular shape, and the inclined portions of the airtight materials 29, 39, and 49 may be in contact with each other at the joint portions 51 and 52.

[0051] The embodiment described above provides the following effects. The parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40 are provided with reinforcing members 25, 35, and 45 made of carbon fiber reinforced plastic and arranged at the ends in the left-right direction X (visible direction). The reinforcing members 25, 35, and 45 have visible surface reinforcing parts 252, 352, and 452 that are formed continuously with the outdoor visible surface reinforcing parts 251, 351, and 451 and the indoor visible surface reinforcing parts 253, 353, and 453.

[0052] As a result, by positioning the exterior surface reinforcement parts 251, 351, 451 and the interior surface reinforcement parts 253, 353, 453 on the outside in the depth direction Y of the parallel moving panel body 20, the sliding moving panel body 30, and the FIX panel body 40, the length of the depth direction Y of the depth surface reinforcement parts 252, 352, 452 can be increased compared to positioning and fixing them on the interior surface of the outermost glass plate in the depth direction Y. At the ends in the left-right direction X of the parallel moving panel body 20, the sliding moving panel body 30, and the FIX panel body 40 (double-glazed glass), the surface and depth can be covered over a wide, continuous area. Therefore, the strength of the parallel moving panel body 20, the sliding moving panel body 30, and the FIX panel body 40 (double-glazed glass) can be increased.

[0053] Furthermore, the reinforcing members 25, 35, and 45 are made of carbon fiber reinforced plastic. This allows the double-glazed glass (parallel moving panel body 20, sliding moving panel body 30, fixed panel body 40) to have sufficient strength to construct the building components without a frame, while also ensuring thermal insulation. In addition, the adhesive A can be covered by the exterior surface reinforcing parts 251, 351, and 451 of the reinforcing members 25, 35, and 45, thus protecting the adhesive A from ultraviolet rays. The adhesive A can also be covered by the interior surface reinforcing parts 253, 353, and 453 of the reinforcing members 25, 35, and 45, thus protecting the adhesive A from ultraviolet rays.

[0054] Furthermore, in this embodiment, the reinforcing members 25, 35, and 45 are formed in a continuous U-shape in cross-section, with the outdoor-side visible surface reinforcing portions 251, 351, and 451, the interior surface reinforcing portions 252, 352, and 452, and the indoor-side visible surface reinforcing portions 253, 353, and 453 being formed in a continuous U-shape. As a result, at the left-right X ends of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40 (double-glazed glass), the outer visible surface and interior surface of the outdoor side Y1 and the outer interior surface of the indoor side Y2 can be covered over a wide, continuous U-shape, thereby increasing the strength of the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40 (double-glazed glass).

[0055] Furthermore, in this embodiment, the carbon fiber reinforced plastic constituting the reinforcing members 25, 35, and 45 is constructed by bundling multiple fibers extending in a direction intersecting the width direction of the reinforcing members 25, 35, and 45 and fixing them with resin. Compared to the case where the carbon fiber reinforced plastic is constructed by solidifying multiple individual fibers, the bundling of multiple fibers extending in a direction intersecting the width direction of the reinforcing members 25, 35, and 45 reduces the likelihood of breakage in the longitudinal direction and increases the strength against bending in the longitudinal direction.

[0056] Furthermore, in this embodiment, the thickness T2 of the internal reinforcement sections 252, 352, and 452 is greater than the thicknesses T1 and T3 of the external reinforcement sections (exterior external reinforcement sections 251, 351, and 451, and interior external reinforcement sections 253, 353, and 453). As a result, the joint sections 51 and 52 of the parallel moving panel 20, the sliding panel 30, and the fixed panel 40 can be configured to have impact-resistant strength when opening and closing.

[0057] Furthermore, in this embodiment, airtight materials 28, 38, and 48 are attached to the outer faces of the reinforcing portions 252, 352, and 452 in the left-right direction X. This allows for airtightness between the parallel moving panel body 20, the sliding moving panel body 30, and the fixed panel body 40, thereby improving airtightness performance.

[0058] Furthermore, although not shown in the figures, the parallel moving panel 20, the sliding moving panel 30, and the FIX panel 40 (double-glazed glass) of this embodiment are provided with only spacers at the upper and lower ends, and no reinforcing members are provided. In the parallel moving panel 20, the sliding moving panel 30, and the FIX panel 40 (double-glazed glass), if a pair of reinforcing members 25, 35, and 45 extending in the vertical direction are provided at both outer ends in the left-right direction X, the strength of the sliding moving panel 30 and the FIX panel 40 (double-glazed glass) can be ensured without providing reinforcing members at the upper and lower ends.

[0059] Next, a second embodiment of the present disclosure will be described with reference to Figure 9. In the second embodiment, the configuration of the end portion on the joint 51A side between the parallel moving panel body 20 (double-glazed glass) and the sliding moving panel body 30 (double-glazed glass) will be described. Note that the configuration of the end portion on the joint 52 side between the sliding moving panel body 30 and the fixed panel body 40 is the same, so its description will be omitted here.

[0060] In the second embodiment, in addition to the configuration of the first embodiment, decorative materials 26 and 36 are attached to the reinforcing members 25 and 35, which is the main difference from the first embodiment. In the description of the second embodiment, components similar to those in the first embodiment are denoted by the same reference numerals in the drawings, and their descriptions are omitted.

[0061] As shown in Figure 9, decorative materials 26 and 36 are attached to one of the pair of facing surfaces (outside Y1 and inside Y2) on the outside of the reinforcing members 25 and 35 in the depth direction Y of the second embodiment. The decorative materials 26 and 36 are connected to the facing surfaces on the outside of the reinforcing members 25 and 35 in the depth direction Y and extend outward in the left-right direction X so as to cover the joint portion 51A between the parallel moving panel body 20 and the sliding moving panel body 30.

[0062] In this embodiment, the decorative material 26 attached to the parallel moving panel body 20 is connected to the indoor side Y2 (outside) surface of the indoor side facing surface reinforcing portion 253 of the reinforcing member 25 attached to the parallel moving panel body 20 in the depth direction Y, at the end of the parallel moving panel body 20 on the joint portion 51A side. The decorative material 26 extends from the indoor side Y2 surface of the indoor side facing surface reinforcing portion 253 toward the X2 side (outside) in the left-right direction X. The decorative material 26 extends toward the sliding panel body 30, and at a position away from the indoor side Y2 surface of the indoor side facing surface reinforcing portion 353 of the reinforcing member 35 of the sliding panel body 30 toward the indoor side Y2, it extends in the left-right direction X parallel to the indoor side facing surface Y2 surface of the indoor side facing surface reinforcing portion 353.

[0063] The decorative material 26 extends in the left-right direction X while covering the gap S in the joint 51A between the parallel moving panel body 20 and the sliding moving panel body 30, and the airtight materials 28 and 38 placed in the joint 51A from the indoor side Y2, and also covering the indoor side visible surface reinforcing portion 353 of the sliding moving panel body 30 from the indoor side Y2. This improves the aesthetic appearance of the joint 51A between the parallel moving panel body 20 and the sliding moving panel body 30.

[0064] Furthermore, the decorative material 36 attached to the sliding panel body 30 is connected to the outer surface Y1 (outside) of the outdoor surface reinforcing portion 351 of the reinforcing member 35 attached to the sliding panel body 30 in the depth direction Y, at the end of the sliding panel body 30 on the joint portion 51A side. The decorative material 36 extends from the outer surface Y1 of the outdoor surface reinforcing portion 351 toward the X1 side (outside) in the left-right direction X. The decorative material 36 extends toward the parallel sliding panel body 20, and at a position away from the outer surface Y1 of the outdoor surface reinforcing portion 251 of the reinforcing member 25 of the parallel sliding panel body 20 toward the outdoor surface Y1, it extends in the left-right direction X parallel to the outer surface Y1 of the outdoor surface reinforcing portion 251.

[0065] The decorative material 36 extends in the left-right direction X while covering the gap S in the joint 51A between the parallel moving panel body 20 and the sliding moving panel body 30, and the airtight materials 28 and 38 placed in the joint 51A from the outdoor side Y1, and also covering the outdoor side visible surface reinforcement portion 251 of the parallel moving panel body 20 from the outdoor side Y1. This improves the aesthetic appearance of the joint 51A between the parallel moving panel body 20 and the sliding moving panel body 30.

[0066] The decorative materials 26 and 36 may be made of the same material as the reinforcing members 25 and 35, or they may be made of a different material. In this embodiment, the decorative materials 26 and 36 are made of the same carbon fiber reinforced plastic as the reinforcing members 25 and 35. The decorative materials 26 and 36 may be made of, for example, aluminum or resin.

[0067] Next, a third embodiment of the present disclosure will be described with reference to Figure 10. In the third embodiment, the configuration of the end portion on the joint side 51B between the parallel moving panel body 20 (double-glazed glass) and the sliding moving panel body 30 (double-glazed glass) will be described. Note that the configuration of the end portion on the joint side 52 between the sliding moving panel body 30 and the fixed panel body 40 is the same, so its description will be omitted here.

[0068] In the third embodiment, the positions of the spacers 24 and 34 and the configuration of the reinforcing members 25A and 35A differ mainly from those of the first embodiment. In the description of the third embodiment, components similar to those in the first embodiment are denoted by the same reference numerals in the drawings, and their descriptions are omitted.

[0069] As shown in Figure 10, in the third embodiment, the spacers 24 and 34 placed between the three glass plates (outer glass plates 21, 31, 41, intermediate glass plates 22, 32, 42, and inner glass plates 23, 33, 43) are positioned further inward in the left-right direction X than in the first embodiment.

[0070] In the third embodiment, the parallel moving panel body 20 and the sliding moving panel body 30 are provided with reinforcing members 25A and 35A at their outer ends in the left-right direction X on the joint portion 51B side. Similar to the first embodiment, the reinforcing members 25A and 35A extend vertically (up and down) at the ends of the parallel moving panel body 20 and the sliding moving panel body 30 on the joint portion 51B side, respectively. Similar to the first embodiment, the reinforcing members 25A and 35A are made of carbon fiber-reinforced plastics (CFRP).

[0071] The reinforcing member 25A of the parallel moving panel body 20 includes an indoor surface reinforcing portion 255 (surface reinforcing portion) arranged along the visible surface of the indoor side Y2 (outside) of the indoor side glass plate 23, a depth reinforcing portion 256 (depth reinforcing portion) arranged along the depth surface of the parallel moving panel body 20, two protrusions 257, 258 projecting in a rectangular shape from the depth reinforcing portion 256 inward in the left-right direction X of the parallel moving panel body 20 (towards the X1 side of the left-right direction X), and a decorative portion 259 extending towards the X2 side from the end of the indoor surface reinforcing portion 255 on the X2 side of the left-right direction X.

[0072] The interior-side visible surface reinforcement portion 255 and the interior surface reinforcement portion 256 of the reinforcing member 25A are formed continuously and are formed in an L-shape in cross-section. As a result, by positioning the interior-side visible surface reinforcement portion 255 along the outer visible surface in the interior direction Y of the parallel moving panel body 20, the length of the interior surface reinforcement portion 256 in the interior direction Y can be made longer than if it were positioned and fixed on the inner visible surface of the outermost glass plate in the interior direction. Therefore, the left-right X end of the parallel moving panel body 20 can be covered by a long L-shaped portion formed by the interior-side visible surface reinforcement portion 255 and the interior surface reinforcement portion 256 of the reinforcing member 25A, thereby increasing the strength of the parallel moving panel body 20 (double-glazed glass).

[0073] The protruding portion 257 protrudes in a rectangular shape from the outdoor side Y1 portion of the inner surface of the inner surface reinforcement portion 256 toward the inside of the parallel moving panel body 20 in the left-right direction X (towards the X1 side of the left-right direction X), and is positioned between the outdoor glass plate 21 and the intermediate glass plate 22. The visible surface of the outdoor side Y1 of the protruding portion 257 is fixed to the visible surface of the indoor side Y2 (inside) of the outdoor glass plate 21 with adhesive A.

[0074] The protruding portion 258 protrudes in a rectangular shape from the indoor side Y2 portion of the inner surface of the inner surface reinforcement portion 256 toward the inside of the parallel moving panel body 20 in the left-right direction X (towards the X1 side of the left-right direction X), and is positioned between the intermediate glass plate 22 and the indoor side glass plate 23. The visible surface of the protruding portion 258 on the indoor side Y2 is fixed to the visible surface of the indoor side glass plate 23 on the outdoor side Y1 (inside) with adhesive A.

[0075] The decorative part 259 covers the gap S in the joint 51B between the parallel moving panel body 20 and the sliding moving panel body 30, and the airtight materials 28 and 38 placed in the joint 51B, from the indoor side Y2, and extends from the end of the indoor side facing surface reinforcement part 255 on the X2 side in the left-right direction X to the X2 side in the left-right direction X. This improves the aesthetic appearance of the joint 51B between the parallel moving panel body 20 and the sliding moving panel body 30.

[0076] The reinforcing member 35A of the sliding panel body 30 includes an outdoor surface reinforcing portion 355 (surface reinforcing portion) arranged along the visible surface of the outdoor side Y1 (outside) of the outdoor glass plate 31, a depth reinforcing portion 356 (depth reinforcing portion) arranged along the depth surface of the sliding panel body 30, two protruding portions 357 and 358 that project in a rectangular shape from the depth reinforcing portion 356 inward in the left-right direction X (towards the X2 side of the left-right direction X) of the sliding panel body 30, and a decorative portion 359 that extends towards the X1 side from the end of the outdoor surface reinforcing portion 355 on the X1 side in the left-right direction X.

[0077] The exterior-facing surface reinforcement portion 355 and the interior surface reinforcement portion 356 of the reinforcing member 35A are formed continuously and are L-shaped in cross-section. As a result, by positioning the exterior-facing surface reinforcement portion 355 along the exterior surface in the interior direction Y of the sliding panel body 30, the length of the interior surface reinforcement portion 356 in the interior direction Y can be made longer than if it were positioned and fixed on the interior surface of the outermost glass plate in the interior direction. Therefore, the left-right X end of the sliding panel body 30 can be covered by a long L-shaped portion formed by the exterior-facing surface reinforcement portion 355 and the interior surface reinforcement portion 356 of the reinforcing member 35A, thereby increasing the strength of the sliding panel body 30 (double-glazed glass).

[0078] The protruding portion 357 protrudes in a rectangular shape from the indoor side Y2 portion of the inner surface of the reinforcing portion 356 in the left-right direction X direction inward (towards the X2 side of the left-right direction X) of the sliding panel body 30, and is positioned between the indoor side glass plate 33 and the intermediate glass plate 32. The visible surface of the protruding portion 357 on the indoor side Y2 is fixed to the visible surface of the outdoor side Y1 (inward) of the indoor side glass plate 33 with adhesive A.

[0079] The protruding portion 358 protrudes in a rectangular shape from the outdoor side Y1 portion of the inner surface of the reinforcing portion 356 in the left-right direction X direction inward (towards the X2 side of the left-right direction X) of the sliding panel body 30, and is positioned between the intermediate glass plate 32 and the outdoor glass plate 31. The visible surface of the protruding portion 358 on the outdoor side Y1 is fixed to the visible surface of the outdoor side Y2 (inward) of the outdoor glass plate 31 with adhesive A.

[0080] The decorative part 359 covers the gap S in the joint 51B between the parallel moving panel body 20 and the sliding moving panel body 30, and the airtight materials 28 and 38 placed in the joint 51B, from the outdoor side Y1, and extends from the end of the outdoor surface reinforcing part 355 on the X1 side in the left-right direction X toward the X1 side in the left-right direction X. This improves the aesthetic appearance of the joint 51B between the parallel moving panel body 20 and the sliding moving panel body 30.

[0081] Next, a fourth embodiment of the present disclosure will be described with reference to Figure 11. In the fourth embodiment, the location where the reinforcing members 25A and 35A are fixed with adhesive A differs from that of the third embodiment. The other components of the fourth embodiment are the same as those of the third embodiment, and therefore the same reference numerals are used in the drawings, and their descriptions are omitted.

[0082] As shown in Figure 11, in the fourth embodiment, in the reinforcing member 25A of the parallel moving panel body 20, the visible surface of the projection 257 on the outdoor side Y1 is fixed to the visible surface of the outdoor side Y2 (inside) of the outdoor glass plate 21 with adhesive A, similar to the third embodiment. Furthermore, in the fourth embodiment, in the reinforcing member 25A of the parallel moving panel body 20, instead of the visible surface of the projection 258 on the indoor side Y2 being fixed to the visible surface of the outdoor side Y1 (inside) of the indoor glass plate 23 with adhesive A as in the third embodiment, the visible surface of the indoor side visible surface reinforcing portion 255 of the reinforcing member 25A on the outdoor side Y1 is fixed to the visible surface of the indoor side Y2 (outside) of the indoor glass plate 23 with adhesive A.

[0083] Furthermore, in the fourth embodiment, in the reinforcing member 35A of the sliding panel body 30, the visible surface of the protruding portion 357 on the indoor side Y2 is fixed to the visible surface of the indoor side glass plate 33 on the outdoor side Y1 (inside) with adhesive A, similar to the third embodiment. Also, in the fourth embodiment, in the reinforcing member 35A of the sliding panel body 30, instead of the visible surface of the protruding portion 358 on the outdoor side Y1 being fixed to the visible surface of the outdoor side glass plate 31 on the indoor side Y2 with adhesive A as in the third embodiment, the visible surface of the outdoor side visible surface reinforcing portion 355 of the reinforcing member 35A on the indoor side Y2 is fixed to the visible surface of the outdoor side glass plate 31 on the outdoor side Y1 (outside) with adhesive A.
