DETAILED DESCRIPTION OF THE INVENTION

[0008] 1 and 2, in this embodiment, an outer 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 outer batten sash 1 comprises a composite frame 2 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) installed 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 Figure 3) is referred to 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 facing the wall, the direction perpendicular to the paper in Figure 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 Figure 3) is referred to as the up-down direction Y. Furthermore, 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 they are installed in the opening.

[0010] The composite frame 2 of the outer frame sash 1 has a fixed shaped structure in which a metal frame and a resin frame are fixed by fitting them 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 connect both ends of the upper frame 10 to both ends of the lower frame 20 and extend 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 to each other.

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

[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, lower frame 20, and vertical frame 30 that make up 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 space it away from the double-glazing 3. Surface clearances are provided between the inner and outer surfaces of the double-glazing 3 and both side portions of the glass receiving portion 2A.

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

[0016] 3 and 5, the metal upper frame 10A of the upper frame 10 includes 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 from 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 positioned at a height equal to or higher than the glass receiving portion 2A of the lower frame 20, and has a size sufficient for inserting the double-glazed glass 3.

[0017] As shown in Figure 5, an upper frame outer glass holder 14 is formed at the lower end of the outer wall 12. A lower frame inner glass holder 15 is formed at the lower end of the inner wall 13, and has a pair of engagement recesses 15A, 15B that open toward the glass receiving portion 2A and are aligned in the vertical direction Y. An indoor attachment 5 engages with the first engagement recess 15A and the second engagement recess 15B. A lead bead 7 is attached to the indoor attachment 5. The lead 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 protrudes up and down. The second engagement recess 15B located below the first engagement recess 41 is not formed with the protruding piece 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 with the lead bead 7. The first engagement portion 51 extends vertically from a tip that protrudes indoors from the upper end of the indoor side attachment 5. 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 at the top and bottom by the protruding piece 15a of the first engagement recess 15A, preventing the indoor side attachment 5 from falling out of 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 height higher 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, the outdoor side holding line L1 and the indoor side holding line L2 are offset from each other in the vertical direction Y, forming a step.

[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 from a middle portion of the lower wall 21 in the indoor-outdoor direction Y. The outdoor side of the lower wall 21, the outer wall 22, and the inner wall 23 form a glass receiving portion 2A. 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 engagement recess 25A opening toward the glass receiving portion 2A is formed at the upper end of the inner wall 23. A second engagement portion 52 of the indoor-side attachment 5 engages with the engagement recess 25A. The indoor-side attachment 5 attached to the lower frame inner glass holding portion 25 is the same as the indoor-side attachment 5 attached to the upper frame inner glass holding portion 25 of the upper frame 10. The indoor-side attachments 5 of the upper frame 10 and the lower frame 20 are installed upside down, respectively. An interior 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 interior surface 3 a of the double glazing 3 on the interior 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, the outdoor side holding line L3 and the indoor side holding line L4 are offset from each other in the vertical direction Y, forming a step.

[0023] The pre-attached beads 7 provided on 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-glazing unit 3. The pre-attached beads 7 have a mating recess 71 (see Figure 5) that fits into the third engagement portion 53 of the indoor attachment 5. The pre-attached bead 7 is fixed with the mating protrusion 71 mated with 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 double-glazing unit 3 are filled with a packing material 9 consisting of a backup material 9A and a sealing material 9B. In this way, the double-glazing unit 3 is held 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 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 an intermediate 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 portion 2A.

[0025] In the outer flared sash 1, when the outer flared 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 Figure 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 ledge 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 ledge 4 has a metal ledge 4A made of metal that holds the indoor side inner surface 3a of the double-glazed glass 3, and a resin ledge 4B that is provided on the indoor side of the metal ledge 4A. An end cap (not shown) is fitted into the lower end of the inner ledge 4. The metal ledge 4A and the resin ledge 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 metal vertical 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 toward the glass receiving portion 2A and are aligned in the left-right direction X. An indoor-side attachment 5 having the same shape as those used in the upper frame 10 and lower frame 20 described above is engaged with the engagement recesses 44. A lead bead 7 is attached to the indoor-side attachment 5. This lead bead 7 is provided in close contact with the inner surface 3a of the indoor-side of the double-glazed glass 3. The fitting recess 71 of the lead bead 7 is fixed by being fitted into the third engagement portion 53 of the indoor-side attachment 5.

[0028] A removable outer shim 6 extending inward 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 protrusions 31a, 32a that protrude toward the glass receiving portion 2A are formed at the corner between the side wall 31 and the outdoor wall 32. A base end portion 61 of the outer shim 6 engages with the locking protrusions 31a, 32a. A gasket 9 is provided at an engagement portion 62 formed at the end of the outer shim 6 opposite the base end portion 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 double-glazed glass 3.

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

[0030] In this way, the double-glazed glass 3 is held in place within the glass receiving section 2A by the leading bead 7 and the packing material 9, sandwiched between them on both sides in the indoor-outdoor direction Z. 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 double-glazed glass 3 facing outdoors.

[0031] In the above-described externally battened sash 1, the vertical frame 30 has an inner and outer battened structure with an inner batten 4 and an outer batten 6. In the externally battened sash 1, when attaching 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 an indoor-side attachment 5 is attached to the upper frame 10 and lower frame 20, and a pre-attached bead 7 is attached to the indoor-side attachment 5.

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

[0033] Next, the operation of the externally flared 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 flared sash 1 according to this embodiment is a composite sash made of a metal frame, such as aluminum, and a resin frame, with external flared specifications, which improves thermal insulation and prevents condensation by using resin profiles on the indoor side. This embodiment ensures the installation of double-glazed glass 3 from the outdoors using external flared glazing, while achieving a thermally insulated structure and a pressure-equalizing structure for high-rise floors.

[0034] With conventional outer battens, it may not be possible to cast indoor and outdoor sealant between glass panels. For example, if a pillar or other object is installed on the indoor side of a building and the seal cannot be cast from the indoor side, a pre-attached bead may be used. In such cases, this embodiment can flexibly respond by attaching or not attaching the indoor attachment 5 depending on the site conditions.

[0035] In this embodiment, only the vertical frame 30 is configured with an external batten, allowing components such as the upper frame 10, lower frame 20, and end caps to be used interchangeably. The external batten 6 also allows the vertical frame 30 to use existing vertical frame battening and resin vertical frame materials. For example, as in this embodiment, a composite sash with an internal batten and a composite frame consisting of an aluminum frame (metal frame) and a resin frame can be used to easily convert to an external batten specification. In this case, the upper frame 10 and lower frame 20 can be used interchangeably with existing internal battening. Therefore, by using an indoor attachment 5 on the internal batten 4 of the vertical frame 30, only the vertical frame 30 can be configured with an external batten specification.

[0036] In this embodiment, the insertion allowance of the double-glazing glass 3 in the upper frame 10 is set large, so it can be inserted by the height of the glass groove (glass receiving portion 2A) in the lower frame 20 of the double-glazing glass 3. In other words, the double-glazing glass 3 can be inserted in the vertical direction Y using a push-in mechanism. 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 an outer batten sash 1 with an outer batten specification such as this embodiment, the protruding tip 6a of the outer batten 6 in the vertical frame 30 can be aligned with the protruding tip 43a of the metal batten 4A of the inner batten 4. This makes it possible to make the exterior designs of the outer batten specification and the inner batten specification the same, and even when sashes of both specifications are installed side by side, they can be installed without compromising the exterior 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 that the double-glazed glass 3 can be incorporated into the composite frame 2 from the outside, while achieving an insulating structure and preventing 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 configured to be detachable, 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 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, 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 in the upper frame 10, but this height relationship is not limiting. For example, both lower ends 14a, 15b may be at the same height.

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

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