DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] 1 and 2, in this embodiment, an exterior batten sash 1, which is a fixed window (fixed window) installed in an opening of a building, will be described as an example of a fixture. The exterior batten sash 1 comprises a composite frame 2 (composite frame) formed in a rectangular frame shape, a double-glazed glass (glass panel) 3 such as double glass fitted into the composite frame 2, and battens (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 that forms the opening of the building, the left-right direction on the paper in Fig. 3) is referred to as the indoor-outdoor direction Z, the horizontal direction connecting the left side and right side when viewed from the direction in which the opening of the building penetrates the wall (the direction facing the wall, the direction perpendicular to the paper in Fig. 3) is referred to 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 on the paper in Fig. 3) is referred to as the up-down direction Y. Also, each member and part that constitutes the outer batten sash 1 will be described using the indoor-outdoor direction Z and the left-right direction X in the position in which it is installed in the opening.

[0010] The composite frame 2 of the outer batten sash 1 has a shaped member fixed 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 extending in the left-right direction X, and vertical frames 30 connecting both ends of the upper frame 10 to both ends of the lower frame 20 and extending in the up-down direction Y. The composite frame 2 is formed into a rectangular frame shape by the upper frame 10, the lower frame 20, and the left and right vertical frames 30, 30.

[0011] 3, the upper frame 10 has a metal upper frame 10A provided on the outdoor side and made of a metal shaped material such as an aluminum alloy, and a resin upper frame 10B provided on the indoor side and made of a resin shaped material. The metal upper frame 10A and the resin upper frame 10B are connected.

[0012] The lower frame 20 has a metal lower frame 20A provided on the outdoor side and formed from a metal shaped material such as an aluminum alloy, and a resin lower frame 20B provided on the indoor side and formed from a resin shaped material. The metal lower frame 20A and the resin lower frame 20B are connected.

[0013] 4, the vertical frame 30 has a metal vertical frame 30A provided on the outdoor side and made of a metal shaped material such as an aluminum alloy, and a resin vertical frame 30B provided on the indoor side and made of a resin shaped material. The metal vertical frame 30A and the resin vertical frame 30B are connected to each other.

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

[0015] Each of the pair of vertical frames 30, 30 has an inner batten 4 provided in the interior side clearance and an outer batten 6 provided in the exterior side clearance in the glass receiving portion 2A.

[0016] 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 at a middle portion of the upper wall 11 in the indoor-outdoor direction Y. A glass receiving portion 2A (glass groove) is formed by the outdoor side of the upper wall 11, the outer wall 12, and the inner wall 13. The glass receiving portion 2A of the upper frame 10 is provided at a height equal to or higher than the glass receiving portion 2A of the lower frame 20, and has a sufficient dimension for inserting the insulating glass 3.

[0017] As shown in Fig. 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, and has a pair of engagement recesses 15A, 15B that open to the glass receiving portion 2A side and line up in the up-down direction Y. An indoor attachment 5 is engaged with the first engagement recess 15A and the second engagement recess 15B. A pre-attached bead 7 is attached to the indoor attachment 5. The pre-attached bead 7 is in close contact with the inner surface 3a on the indoor side of the insulating 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 protrudes vertically. The second engagement recess 15B located on the lower side of the first engagement recess 41 is not formed with the protruding piece as described above.

[0019] The indoor side attachment 5 has a first engagement portion 51 that engages with the first engagement recess 15A, a second engagement portion 52 that engages with the second engagement recess 15B, and a third engagement portion 53 that engages the leading bead 7. The first engagement portion 51 extends vertically from a tip that protrudes from the upper end of the indoor side attachment 5 to the indoor side. The indoor side attachment 5 is attached to the outdoor side of the inner wall 13 of the metal upper frame 10A with the first engagement piece 51 engaged with the first engagement recess 15A and the second engagement piece 52 engaged with the second engagement recess 15B. At this time, the first engagement piece 51 is held down from above and below by the protruding piece 15a of the first engagement recess 15A, preventing the indoor side attachment 5 from falling off the first engagement 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 higher than 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). In other words, a step is formed between the outdoor side holding line L1 and the indoor side holding line L2, which are offset 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 part of the lower wall 21 in the indoor-outdoor direction Y. The glass receiving part 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 part 24 is formed at the upper end of the outer wall 22. A lower frame inner glass holding part 25 having an engagement recess 25A opening to the glass receiving part 2A side is formed at the upper end of the inner wall 23. The second engagement part 52 of the indoor attachment 5 is engaged with the engagement recess 25A. The indoor attachment 5 attached to the lower frame inner glass holding part 25 is the same as the indoor attachment 5 attached to the upper frame inner glass holding part 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 in which they are inverted upside down. The indoor attachment 5 provided on the lower frame inner glass holding portion 25 has a leading bead 7 attached thereto and is in close contact with the inner surface 3 a of the insulating glass 3 on the indoor side.

[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 lower than 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). In other words, a step is formed between the outdoor side holding line L3 and the indoor side holding line L4, which are offset from each other in the vertical direction Y.

[0023] The pre-attached bead 7 provided on the upper frame inner glass holding portion 15 and the lower frame inner glass holding portion 25 is made of an elastic material such as foamed silicone rubber, and is arranged in close contact with the inner surface 3a on the indoor side of the insulating glass 3. The pre-attached bead 7 has a fitting recess 71 (see FIG. 5) that fits into the third engagement portion 53 of the indoor attachment 5. The pre-attached bead 7 is fixed in a state in which the fitting protrusion 71 is fitted into the third engagement portion 53 of the indoor 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 insulating glass 3 are filled with a packing material 9 consisting of a backup material 9A and a seal material 9B. In this way, the insulating glass 3 is held in the glass mounting portion 2A by being sandwiched from both the indoor side and the outdoor side by the pre-attached bead 7 and the packing material 9.

[0024] As shown in Fig. 4, the metal vertical frame 30A includes 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 from the outdoor end of the side wall 31 in the left-right direction X toward the inside of the composite frame 2. The indoor wall 33 extends in the left-right direction X at a middle portion of the side wall 31 in the indoor / outdoor direction Z. The side wall 31, the outdoor wall 32, and the indoor wall 33 form a glass receiving section 2A.

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

[0026] As shown in Fig. 6, the resin vertical frame 30B is connected to the indoor side end of the side wall 31 of the metal vertical frame 30A. An inner ridge 4 is provided between the resin vertical frame 30B and the tip of the indoor wall 33 of the metal vertical frame 30A (see Figs. 1 and 2). The inner ridge 4 has a metal ridge 4A made of metal that holds the indoor side inner surface 3a of the insulating glass 3, and a resin ridge 4B provided on the indoor side of the metal ridge 4A. An end cap (not shown) is fitted into the lower end of the inner ridge 4. The metal ridge 4A and the resin ridge 4B are connected and configured as a single unit.

[0027] The metal batten 4A is provided with an outer batten wall 43 that is arranged on an extension of the indoor wall 33 of the vertical metal frame 30A in the left-right direction X. The outdoor surface of the outer batten wall 43 has a pair of engagement recesses 44 that open to the glass receiving portion 2A side and are aligned in the left-right direction X. An indoor attachment 5 having the same shape as that used for the upper frame 10 and lower frame 20 described above is engaged with the engagement recesses 44. A pre-attached bead 7 is attached to the indoor attachment 5. This pre-attached bead 7 is provided in close contact with the inner surface 3a on the indoor side of the insulating glass 3. The fitting recess 71 of the pre-attached bead 7 is fixed in a fitted state with the third engagement portion 53 of the indoor attachment 5.

[0028] A removable outer flange 6 extending inwardly of the composite frame 2 in the left-right direction X is provided at the corner between the side wall 31 and the outdoor wall 32 of the metal vertical frame 30A. Locking projections 31a, 32a protruding toward the glass receiving portion 2A are formed at the corner between the side wall 31 and the outdoor wall 32. A base end 61 of the outer flange 6 engages with the locking projections 31a, 32a. A gasket 9 is provided at an engagement portion 62 formed at the end of the outer flange 6 opposite the base end 61 in the left-right direction X, and the engagement portion 62 is in close contact with the outer surface 3b on the outdoor side of the insulating glass 3.

[0029] The outer flange 6 has the base end 61 which engages with the locking projections 31a, 32a of the side wall 31 and the outdoor wall 32, and the engagement portion 62 which extends from the base end 61 in the left-right direction X toward the opening side and holds the gasket material 9. The protruding tip 6a of the outer flange 6 approximately coincides with the protruding tip 43a of the metal flange 4A of the inner flange 4 in the left-right direction X when engaged with and attached to the outdoor wall 32 of the metal vertical frame 30A.

[0030] In this way, the insulating glass 3 is held in the glass receiving part 2A by being sandwiched from both sides in the indoor / outdoor direction Z between the pre-attached bead 7 and the packing material 9. The packing material 9 is made of a backup material 9A made of an elastic material such as foamed silicone rubber, and a sealing material 9B, and is placed in contact with the outer surface 3b of the insulating glass 3 facing outdoors.

[0031] In the above-mentioned externally-flanged sash 1, the vertical frame 30 has an inner and outer flaps structure with an inner flaps 4 and an outer flaps 6. In the externally-flanged sash 1, when the double-glazed glass 3 is attached to the composite frame 2 from the outdoor side, the double-glazed glass 3 is removed from the vertical frame 30, and an indoor side attachment 5 is attached to the upper frame 10 and the lower frame 20, and a pre-attached bead 7 is attached to the indoor side attachment 5.

[0032] After that, the upper part of the insulating glass 3 is inserted into the glass receiving part 2A of the upper frame 10 by a push-in method, and then the insulating glass 3 is dropped into the glass receiving part 2A of the lower frame 20, so that the insulating glass 3 is fitted into the composite frame 2. After that, as shown in Figure 4, a packing material 9 is provided on the outer bolster 6 attached to the vertical frame 30.

[0033] Next, the function of the externally battened sash 1 according to this embodiment will be described in detail with reference to the drawings. As shown in Figures 3 and 4, the externally battened sash 1 according to this embodiment is a composite sash made of a metal frame such as aluminum and a resin frame with externally battened specifications, which improves thermal insulation and prevents condensation by using a resin profile on the indoor side. This embodiment can achieve a thermally insulated structure and an equal pressure structure for high floors while ensuring the installation of double-glazed glass 3 from the outdoors using the externally battened structure.

[0034] With conventional outer battens, there are cases where it is not possible to cast indoor and outdoor sealant sandwiching a glass panel. For example, when a pillar or the like is installed on the indoor side of a building and it is not possible to cast the sealant from the indoor side, a pre-attached bead may be used. In such cases, in this embodiment, the indoor attachment 5 can be attached or not attached depending on the situation on-site, allowing for flexible response.

[0035] In this embodiment, since only the vertical frame 30 is configured to have an external batten specification, the upper frame 10, lower frame 20, end caps, and other parts can be used for both purposes. The external batten 6 also allows the vertical frame 30 to use the existing vertical frame batten and resin vertical frame material. For example, as in this embodiment, a composite sash with an internal batten and a composite frame made of an aluminum frame (metal frame) and a resin frame can be used to easily change to an external batten specification. In this case, the upper frame 10 and lower frame 20 can be used for both purposes. Therefore, by using the indoor attachment 5 for the internal batten 4 of the vertical frame 30, only the vertical frame 30 can be configured to have an external batten specification.

[0036] In this embodiment, the insertion allowance of the insulating glass 3 in the upper frame 10 is set large, so that the insulating glass 3 can be inserted by the height of the glass groove (glass receiving portion 2A) in the lower frame 20. In other words, the insulating glass 3 can be inserted in the vertical direction Y by a snap-on method. As a result, only the vertical frame 30 can have an outer flange structure, which reduces the number of parts and maintains the safety of the glass holding portion.

[0037] In the outer batten sash 1 with the outer batten specifications as in this embodiment, the protruding tip 6a of the outer batten 6 in the vertical frame 30 can be made to coincide with the protruding tip 43a of the metal batten 4A of the inner batten 4. This makes it possible to make the external designs of the outer batten specifications and the inner batten specifications the same, and even when sashes of both specifications are installed side by side, they can be installed without compromising the external design.

[0038] In this way, in the outer batten sash 1 of this embodiment, the outer batten 6 provided on the vertical frame 30 ensures the installation of the double-glazed glass 3 into the composite frame 2 from the outside, while realizing an insulating structure and preventing the occurrence of condensation on the indoor side.

[0039] Although the embodiments of the fittings according to the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments.

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

[0041] In this embodiment, in the upper frame 10, the lower end 15b of the upper frame inner glass holding portion 15 is set at a position higher than the lower end 14a of the upper frame outer glass holding portion 14, but there is no limitation to this height relationship. For example, both lower ends 14a, 15b may be at the same height.

[0042] In this embodiment, the packing material 9 is used, but glazing may be used instead of the packing material 9. For example, a glazing channel or a glazing bead may be used as the glazing. The glazing channel is formed in a generally U-shaped cross section and is arranged so as to surround the end of the insulating glass 3. The glazing channel is formed by a base portion that abuts against the end face of the insulating glass 3 and rising portions that abut against both side edges of the insulating glass 3. The rising portions have fin portions that protrude toward the insulating glass 3, and the fin portions come into contact with the side edges of the insulating glass 3 to provide an airtight seal.

[0043] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate without departing from the spirit of the present disclosure. [Explanation of symbols]
