[0008] As shown in Figures 1 and 2, in this embodiment, an exterior sash 1, which is a fixed window (non-opening window) installed in an opening of a building, will be described as an example of a building fixture. The exterior sash 1 comprises a composite frame 2 (composite frame) formed in the shape of a rectangular frame, a double-glazed glass (glass panel) 3, such as double-pane glass, fitted into the composite frame 2, and sashes (reference numerals 4 and 6, described later) provided on the left and right sides of the composite frame 2.

[0009] In the following explanation, the direction connecting the outdoor side and the indoor side (the direction perpendicular to the wall forming the opening of the building, the left-right direction in Figure 3) will be defined as the indoor-outdoor direction Z, the horizontal direction connecting the left and right sides when viewed from the direction in which the opening of the building penetrates the wall (the direction opposite to the wall, the direction perpendicular to the plane of the paper in Figure 3) will be defined as the left-right direction X, and the direction perpendicular to the left-right direction X when viewed from the indoor-outdoor direction Z (the up-down direction in Figure 3) will be defined as the up-down direction Y. Furthermore, each member and component constituting the exterior sash 1 will be described using the indoor-outdoor direction Z and the left-right direction X in the position in which they are installed in the opening.

[0010] The composite frame 2 of the exterior sash 1 has a profile fixing structure in which a metal frame and a resin frame are fixed by fitting together (see Figures 3 and 4). The composite frame 2 has an upper frame 10 and a lower frame 20 that extend in the left-right direction X, and vertical frames 30 that extend in the up-down direction Y, connecting both ends of the upper frame 10 and both ends of the lower frame 20, respectively. The composite frame 2 is formed in a rectangular frame shape by the upper frame 10, the lower frame 20, and the left and right vertical frames 30, 30.

[0011] As shown in Figure 3, the upper frame 10 has a metal upper frame 10A that is provided on the outdoor side and is made of a metal profile such as an aluminum alloy, and a resin upper frame 10B that is provided on the indoor side and is made of a resin profile. The metal upper frame 10A and the resin upper frame 10B are connected.

[0012] The lower frame 20 has a metal lower frame 20A, which is provided on the outdoor side and is made of a metal profile such as an aluminum alloy, and a resin lower frame 20B, which is provided on the indoor side and is made of a resin profile. The metal lower frame 20A and the resin lower frame 20B are connected.

[0013] As shown in Figure 4, the vertical frame 30 has a metal vertical frame 30A that is provided on the outdoor side and is made of a metal profile such as an aluminum alloy, and a resin vertical frame 30B that is provided on the indoor side and is made of a resin profile. The metal vertical frame 30A and the resin vertical frame 30B are connected.

[0014] As shown in Figures 3 and 4, the upper frame 10, lower frame 20, and vertical frame 30 that constitute the composite frame 2 are each provided with a U-shaped glass receiving portion 2A (glass groove) in cross-section that is recessed so as to be spaced apart from the double-glazed glass 3. Surface clearance is provided between the inner and outer surfaces of the double-glazed glass 3 and both sides of the glass receiving portion 2A.

[0015] Each pair of vertical frames 30, 30 has an inner glazing edge 4 provided in the indoor side clearance and an outer glazing edge 6 provided in the outdoor side clearance at each glass receiving portion 2A.

[0016] As shown in Figures 3 and 5, the metal upper frame 10A of the upper frame 10 comprises an upper wall 11, an outer wall 12 extending downward from the outdoor end of the upper wall 11, and an inner wall 13 extending downward in the middle of the upper wall 11 in the indoor-outdoor direction Y. The outdoor side of the upper wall 11, the outer wall 12, and the inner wall 13 constitute the glass receiving portion 2A (glass groove). The glass receiving portion 2A of the upper frame 10 is provided at a height greater than or equal to the glass receiving portion 2A of the lower frame 20, and has sufficient dimensions to accommodate the insertion of the double-glazed glass 3.

[0017] As shown in Figure 5, an upper frame outer glass holding portion 14 is formed at the lower end of the outer wall 12. A lower frame inner glass holding portion 15 is formed at the lower end of the inner wall 13, having a pair of engaging recesses 15A and 15B that open towards the glass receiving portion 2A and are aligned in the vertical direction Y. An indoor side attachment 5 is engaged with the first engaging recess 15A and the second engaging recess 15B. A pre-attached bead 7 is attached to the indoor side attachment 5. The pre-attached bead 7 is in close contact with the inner surface 3a on the indoor side of the double-glazed glass 3.

[0018] The opening edge of the first engagement recess 15A, located on the upper side, is provided with a protruding piece 15a that projects vertically. The second engagement recess 15B, located below the first engagement recess 41, does not have a protruding piece as described above.

[0019] The indoor attachment 5 has a first engaging portion 51 engaged with the first engaging recess 15A, a second engaging portion 52 engaged with the second engaging recess 15B, and a third engaging portion 53 for engaging the front bead 7. The first engaging portion 51 extends vertically from the tip protruding indoors from the upper end of the indoor attachment 5. The indoor attachment 5 is attached to the outdoor side of the inner wall 13 of the metal upper frame 10A in a state where the first engaging piece 51 is engaged with the first engaging recess 15A and the second engaging piece 52 is engaged with the second engaging recess 15B. At this time, since the first engaging piece 51 is pressed up and down by the protruding piece 15a of the first engaging recess 15A, the indoor attachment 5 is prevented from falling from the first engaging recess 15A.

[0020] The lower end 13a of the inner wall 13 is at the same height as the lower end 14a of the upper frame outer glass holding portion 14. The upper frame inner glass holding portion 15 is located above the lower end 13a of the inner wall 13. Therefore, the line indicating the position of the lower end 15b of the upper frame inner glass holding portion 15 (the indoor side holding line L2 shown by the two-dot chain line in FIG. 5) is located at a higher height than the line indicating the position of the lower end 14a of the upper frame outer glass holding portion 14 (the outdoor side holding line L1 shown by the two-dot chain line in FIG. 5). That is, a step is formed in a state where the outdoor side holding line L1 and the indoor side holding line L2 are displaced from each other in the vertical direction Y.

[0021] As shown in Fig. 3, the metal lower frame 20A of the lower frame 20 includes a lower wall 21, an outer wall 22 extending upward from the outdoor end of the lower wall 21, and an inner wall 23 extending upward at the middle portion of the lower wall 21 in the indoor-outdoor direction Y. A glass receiving portion 2A is formed by the outdoor side of the lower wall 21, the outer wall 22, and the inner wall 23. A lower frame outer glass holding portion 24 is formed at the upper end of the outer wall 22. A lower frame inner glass holding portion 25 having an engaging recess 25A opening to the glass receiving portion 2A side is formed at the upper end of the inner wall 23. The second engaging portion 52 of the indoor attachment 5 is engaged with the engaging recess 25A. The indoor attachment 5 attached to the lower frame inner glass holding portion 25 is the same as the indoor attachment 5 attached to the upper frame inner glass holding portion 25 of the upper frame 10. The indoor attachments 5 of the upper frame 10 and the lower frame 20 are provided in a state of being vertically inverted. A front bead 7 is attached to the indoor attachment 5 provided on the lower frame inner glass holding portion 25 and is in close contact with the inner surface 3a on the indoor surface side of the multilayer glass 3.

[0022] The upper end 23a of the inner wall 23 is at the same height as the upper end 24a of the lower frame outer glass holding portion 24. The lower frame inner glass holding portion 25 is located below the upper end 23a of the inner wall 23. Therefore, the line indicating the position of the upper end 25a of the lower frame inner glass holding portion 25 (the indoor side holding line L4 shown by the two-dot chain line in Fig. 3) is located at a lower height than the line indicating the position of the upper end 24a of the lower frame outer glass holding portion 24 (the outdoor side holding line L3 shown by the two-dot chain line in Fig. 3). That is, a step is formed in a state where the outdoor side holding line L3 and the indoor side holding line L4 are displaced from each other in the vertical direction Y.

[0023] The pre-attached beads 7 provided in the upper frame inner glass holding portion 15 and the lower frame inner glass holding portion 25 are made of an elastic material such as foamed silicone rubber and are positioned in close contact with the inner surface 3a on the indoor side of the double-glazed glass 3. The pre-attached beads 7 have a fitting recess 71 (see Figure 5) that fits into the third engaging portion 53 of the indoor side attachment 5. The pre-attached beads 7 are fixed in a state where the fitting projection 71 is fitted into the third engaging portion 53 of the indoor side attachment 5. The upper frame outer glass holding portion 14 and the lower frame outer glass holding portion 24 on the outdoor side of the double-glazed glass 3 are filled with packing material 9 consisting of a backup material 9A and a sealing material 9B. In this way, the double-glazed glass 3 is held in place within the glass mounting portion 2A, sandwiched from both the indoor and outdoor sides by the pre-attached beads 7 and the packing material 9.

[0024] As shown in Figure 4, the metal vertical frame 30A comprises a side wall 31, an outdoor wall 32, and an indoor wall 33. The side wall 31 extends along the indoor-outdoor direction Z. The outdoor wall 32 extends inward from the outdoor end of the side wall 31 in the left-right direction X. The indoor wall 33 extends in the left-right direction X at the midpoint of the indoor-outdoor direction Z in the side wall 31. The glass receiving portion 2A is formed by the side wall 31, the outdoor wall 32, and the indoor wall 33.

[0025] In the exterior sash 1, with the exterior trim 6, which will be described later and is attached to the exterior wall 32, removed, the double-glazed glass 3 can be inserted into the glass receiving section 2A from the exterior side without interfering with the pair of left and right vertical frames 30.

[0026] As shown in Figure 6, the resin vertical frame 30B is connected to the indoor end of the side wall 31 of the metal vertical frame 30A. An inner glazing strip 4 is provided between the resin vertical frame 30B and the tip of the indoor wall 33 of the metal vertical frame 30A (see Figures 1 and 2). The inner glazing strip 4 has a metal glazing strip 4A that holds the indoor inner surface 3a of the double-glazed glass 3, and a resin glazing strip 4B provided on the indoor side of the metal glazing strip 4A. An end cap (not shown) is fitted to the lower end of the inner glazing strip 4. The metal glazing strip 4A and the resin glazing strip 4B are connected and constitute a single unit.

[0027] The metal trim 4A is provided with a trim exterior wall 43 that is positioned on the extension line in the left-right direction X of the interior wall 33 of the metal vertical frame 30A. The exterior surface of the trim exterior wall 43 has a pair of engaging recesses 44 that open toward the glass receiving portion 2A and are arranged in the left-right direction X. An interior attachment 5, which has the same shape as those used in the upper frame 10 and lower frame 20 described above, is engaged with the engaging recesses 44. A pre-attached bead 7 is attached to the interior attachment 5. This pre-attached bead 7 is provided in close contact with the interior surface 3a of the double-glazed glass 3. The fitting recess 71 of the pre-attached bead 7 is fixed in a fitted state with the third engaging portion 53 of the interior attachment 5.

[0028] A removable outer trim 6 is provided at the corner between the side wall 31 of the metal vertical frame 30A and the outdoor wall 32, extending inward in the left-right direction X towards the composite frame 2. Locking projections 31a and 32a are formed at the corner between the side wall 31 and the outdoor wall 32, respectively, projecting toward the glass receiving portion 2A. The base end portion 61 of the outer trim 6 engages with the locking projections 31a and 32a. A packing material 9 is provided at the engagement portion 62 formed at the end of the outer trim 6 opposite to the base end portion 61 in the left-right direction X, and is in close contact with the outer surface 3b of the double-glazed glass 3 on the outdoor side.

[0029] The outer trim 6 has a base end portion 61 that engages with the locking projections 31a and 32a of the side wall 31 and the outdoor wall 32, and an engaging portion 62 that extends from the base end portion 61 toward the opening in the left-right direction X and holds the packing material 9. When the outer trim 6 is attached to the outdoor wall 32 of the metal vertical frame 30A, the protruding tip portion 6a of the outer trim 6 is approximately coincident with the protruding tip portion 43a of the metal trim 4A of the inner trim 4 in the left-right direction X.

[0030] In this manner, the double-glazed glass 3 is held within the glass support portion 2A, sandwiched from both sides in the indoor / outdoor direction Z by the pre-installed bead 7 and the packing material 9. The packing material 9 consists of an elastic backing material 9A and a sealing material 9B, such as foamed silicone rubber, and is positioned in contact with the outer surface 3b of the double-glazed glass 3 on the outdoor side.

[0031] In the exterior sash 1 described above, the vertical frame 30 has an interior and exterior sash structure with an interior sash 4 and an exterior sash 6. In the exterior sash 1, when installing the double-glazed glass 3 to the composite frame 2 from the outside, the double-glazed glass 3 is removed from the vertical frame 30, and the interior attachment 5 is attached to the upper frame 10 and the lower frame 20, and a pre-installed bead 7 is attached to the interior attachment 5.

[0032] Subsequently, the upper part of the double-glazed glass 3 is inserted into the glass receiving portion 2A of the upper frame 10 using a sliding mechanism, and then the double-glazed glass 3 is dropped into the glass receiving portion 2A of the lower frame 20, thereby fitting the double-glazed glass 3 into the composite frame 2. After that, as shown in Figure 4, a packing material 9 is provided on the outer trim 6 attached to the vertical frame 30.

[0033] Next, the operation of the exterior sash 1 according to this embodiment will be described in detail based on the drawings. As shown in Figures 3 and 4, the exterior sash 1 according to this embodiment is a composite sash of a metal frame such as aluminum and a resin frame with an exterior sash specification, thereby improving thermal insulation and preventing condensation by using resin profiles on the indoor side. In this embodiment, it is possible to achieve a thermal insulation structure and an equal pressure structure for high floors while ensuring the installation of double-glazed glass 3 from the outside with an exterior sash.

[0034] Conventional exterior moldings may not allow for the application of sealing material to both the interior and exterior surfaces of a glass panel. For example, if columns or other structural elements are present on the interior side of a building, preventing the sealant from being applied from the interior, a pre-applied bead may be used. In such cases, this embodiment allows for flexible adaptation by attaching or not attaching the interior attachment 5 depending on the site conditions.

[0035] In this embodiment, since only the vertical frame 30 is configured with an external trim, parts such as the upper frame 10, lower frame 20, and end caps can be shared. Even with the vertical frame 30, the external trim 6 allows for the sharing of existing vertical frame trims and resin vertical frame materials. For example, as in this embodiment, a composite sash with an internal trim having a composite frame made of an aluminum frame (metal frame) and a resin frame can be easily converted to an external trim specification. In this case, the upper frame 10 and lower frame 20 can be shared with existing frames that use internal trims. Therefore, by using an indoor attachment 5 on the internal trim 4 of the vertical frame 30, only the vertical frame 30 can be made to have an external trim specification.

[0036] In this embodiment, the insertion allowance for the double-glazed glass 3 in the upper frame 10 is set to be large, so that the height of the glass groove (glass receiving portion 2A) of the lower frame 20 in the double-glazed glass 3 can be inserted. In other words, the double-glazed glass 3 can be inserted in the vertical direction Y using a sliding method. Therefore, only the vertical frame 30 can have an external rim structure, reducing the number of parts while maintaining the safety of the glass holding portion.

[0037] In the external trim sash 1 with an external trim specification as in this embodiment, the protruding tip 6a of the external trim 6 on the vertical frame 30 can be made to coincide with the protruding tip 43a of the metal trim 4A of the internal trim 4. Therefore, it is possible to make the external trim specification and the internal trim specification the same in appearance, and even when sashes of both specifications are installed side by side, the appearance can be maintained without any compromise.

[0038] Thus, in the exterior sash 1 according to this embodiment, the exterior sash 6 provided on the vertical frame 30 ensures that the double-glazed glass 3 can be assembled into the composite frame 2 from the outside, while also achieving an insulating structure and preventing condensation on the indoor side.

[0039] The embodiments of the building components described herein have been explained above, but this disclosure is not limited to the embodiments described above.

[0040] For example, in the above embodiment, the outer trim 6 provided on the vertical frame 30 is detachably provided, and the packing material 9 is attached to the outer trim 6, but the configuration is not limited to being detachable. Alternatively, the indoor attachment 5 that can be attached to the inner trim 4 may be omitted, and the pre-attached bead 7 may be attached directly to the inner trim 4.

[0041] In this embodiment, the lower end 15b of the glass holding portion 15 inside the upper frame is set to a higher position than the lower end 14a of the glass holding portion 14 outside the upper frame. However, the height relationship is not limited to this. For example, both lower ends 14a and 15b may be at the same height.

[0042] In this embodiment, packing material 9 is used, but glazing may be used instead of packing material 9. For example, glazing channels or glazing beads may be used as glazing. The glazing channel is formed in a substantially U-shape in cross-section and is arranged to surround the end of the double-glazed glass 3. The glazing channel is formed by a base portion that abuts the end face of the double-glazed glass 3 and rising portions that abut both side edges of the double-glazed glass 3. The rising portions have fin portions that protrude toward the double-glazed glass 3, and these fin portions contact the side edges of the double-glazed glass 3 to provide an airtight seal.

[0043] Furthermore, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, without departing from the spirit of this disclosure. [Explanation of Symbols]
