Description

This disclosure relates to building materials.

Conventionally, in fixtures consisting of fixed windows with inner ridges, watertightness is ensured by a countersunk fit between the upper and lower frames and the vertical frame, as shown in Patent Document 1, for example.

JP 2012-87454 A

However, with conventional fittings with top and bottom stiles and inside and outside stiles, it is not possible to ensure a stile structure in which the top and bottom frames fit into the vertical frame as described above. As a result, the ends of the inside and outside stiles are arranged in a straight line from indoors to outdoors, which can cause light leakage, and furthermore, the structure means that water is blown directly into the straight line, making it difficult to create a highly watertight sash.

This disclosure provides fittings that allow glass panels to be installed from both inside and outside, while blocking the path for water to enter the interior of the building, ensuring watertightness equivalent to that of conventional interior edging specifications, and preventing light leakage.

A fixture according to one embodiment of the present disclosure comprises a frame body provided at an opening and framing all four sides, glass retaining portions formed on the indoor and outdoor sides of the frame body, a glass panel housed in the frame body, a gasket material provided on the outdoor side of the peripheral edge of the glass panel, an attachment engaged with the indoor side of the glass retaining portion, and a bead attached to the attachment and provided on the indoor side of the peripheral edge of the glass panel, wherein the glass retaining portion presses the glass panel in the indoor/outdoor direction via the gasket material and the bead, and the glass retaining portion of at least one of the upper and lower frames of the frame body has an opening side end portion facing the opening side of the frame body in the vertical direction of the indoor and outdoor glass retaining portions, the opening side end portion differing in height between indoors and outdoors.

This is an oblique view of an outer batten sash according to one embodiment of the present disclosure, viewed from the indoor side. FIG. 2 is an exploded perspective view of the outer shim sash shown in FIG. 1 . This is a cross-sectional view of line AA shown in Figure 1, and a vertical cross-sectional view of the outer flange sash. This is a cross-sectional view along line BB shown in Figure 1, and is a horizontal cross-sectional view of the outer flange sash. FIG. 4 is an enlarged view of a main portion of a region indicated by an arrow C in FIG. 3 . 5 is an enlarged view of a main portion of a region indicated by an arrow D in FIG. 4 .

As shown in Figures 1 and 2, in this embodiment, an external batten sash 1, which is a fixed window (fixed window) installed in an opening of a building, is described as an example of a fixture. The external 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 glazing that is 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.

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 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 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 the up-down direction Y. In addition, each member and part that constitutes the outer 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 at the opening.

The composite frame 2 of the outer 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.

As shown in FIG. 3, the upper frame 10 has a metal upper frame 10A provided on the outdoor side and formed from a metal shaped material such as an aluminum alloy, and a resin upper frame 10B provided on the indoor side and formed from a resin shaped material. The metal upper frame 10A and the resin upper frame 10B are connected.

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.

As shown in FIG. 4, the vertical frame 30 has a metal vertical frame 30A provided on the outdoor side and formed from a metal shaped material such as an aluminum alloy, and a resin vertical frame 30B provided on the indoor side and formed from a resin shaped material. The metal vertical frame 30A and the resin vertical frame 30B are connected.

As shown in Figures 3 and 4, the upper frame 10, lower frame 20, and vertical frame 30 that make up the composite frame 2 each have 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. Surface clearances are provided between the inner and outer surfaces of the insulating glass 3 and both sides of the glass receiving portion 2A.

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

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 at 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 form a glass receiving portion 2A (glass groove). The glass receiving portion 2A of the upper frame 10 is set at a height equal to or higher than the glass receiving portion 2A of the lower frame 20, and is of sufficient size to allow for the insertion of the insulating glass 3.

As shown in FIG. 5, an upper frame outer glass retaining portion 14 is formed at the lower end of the outer wall 12. A lower frame inner glass retaining portion 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 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.

The opening edge of the first engagement recess 15A located on the upper side is provided with a protruding piece 15a that protrudes upward and downward. The second engagement recess 15B located below the first engagement recess 41 does not have the protruding piece described above.

The indoor 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 attachment 5 to the indoor side. The indoor 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 attachment 5 from falling out of the first engagement recess 15A.

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 Figure 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 Figure 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 to form a step.

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 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 the glass receiving portion 2A. The upper end of the outer wall 22 is formed with a lower frame outer glass holding portion 24. The upper end of the inner wall 23 is formed with a lower frame inner glass holding portion 25 having an engagement recess 25A that opens to the glass receiving portion 2A side. The second engagement portion 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 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 in which they are inverted upside down. The indoor attachment 5 provided on the lower frame inner glass holding portion 25 has a pre-attached bead 7 attached and is in close contact with the inner surface 3a on the indoor side of the insulating glass 3.

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 to form a step.

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 double-glazing 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 double-glazing 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 3 is held in a state in which it is sandwiched from both the indoor and outdoor sides by the pre-attached bead 7 and the packing material 9 within the glass mounting portion 2A.

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 the middle 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 the glass receiving section 2A.

With the external shim sash 1, when the external shim 6 (described later) attached to the exterior wall 32 is 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.

As shown in FIG. 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 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 FIG. 1 and FIG. 2). The inner ridge 4 has a metal ridge 4A made of metal that holds the inner surface 3a of the indoor side of the double-glazed 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.

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 to the glass receiving portion 2A side and are aligned in the left-right direction X. The engagement recesses 44 are engaged with an indoor attachment 5 of the same shape as those used for the upper frame 10 and lower frame 20 described above. 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 double-glazed glass 3. The fitting recess 71 of the pre-attached bead 7 is fixed in a state where it is fitted into the third engagement portion 53 of the indoor attachment 5.

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

The outer shim 6 has a base end 61 that engages with the locking projections 31a, 32a of the side wall 31 and the exterior wall 32, and an engagement portion 62 that extends from the base end 61 toward the opening in the left-right direction X to hold the packing material 9. 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 when engaged and attached to the exterior wall 32 of the metal vertical frame 30A.

In this way, the insulating glass 3 is held in the glass receiving portion 2A by the pre-attached bead 7 and the packing material 9, sandwiched 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 insulating glass 3 on the outdoor side.

In the above-mentioned externally-flanged sash 1, the vertical frame 30 has an internal and externally-flanged structure with an internal flank 4 and an external flank 6. In the externally-flanged sash 1, when the double-glazed glass 3 is attached to the composite frame 2 from the outside, the double-glazed glass 3 is removed from the vertical frame 30, and an indoor 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 attachment 5.

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

Next, the function of the outer edge sash 1 according to this embodiment will be described in detail with reference to the drawings. As shown in Figures 3 and 4, the outer edge sash 1 according to this embodiment allows the installation of double glazing 3 from both inside and outside, while the heights of the upper and lower ends (opening side ends) of the outer glass holding parts 14, 24 and the inner glass holding parts 15, 25 in the upper frame 10 and lower frame 20 are different indoors and outdoors. This makes it possible to block the linear path in which water can be blown directly in the indoor/outdoor direction Z.

In this embodiment, the opening side ends of the outer glass holding parts 14, 24 and the inner glass holding parts 15, 25 in the upper frame 10 and the lower frame 20 are offset in the vertical direction Y, thereby suppressing light leakage.

In this embodiment, the double-glazed glass 3 can be installed from both inside and outside, and as described above, the same watertightness as that of the inner edge specification can be achieved. It is also possible to block the path of water inflow at the metal-to-metal joint between the upper frame 10 and the lower frame 20 on the outdoor side.

In this embodiment, the composite frame 2 is made of a metal frame and a resin frame, and a pre-attached bead 5 that presses the composite glass 3 from the indoor side is attached to the inner batten 4. The resin frame 10B that constitutes the indoor side and the pre-attached bead 5 overlap in the indoor/outdoor direction Z, so that the sash can maintain a higher level of watertightness than conventional sashes with inner and outer batten specifications.

In this embodiment, the lower end 15b of the upper frame inner glass holding portion 15 is set at a higher position than the lower end 14a of the upper frame outer glass holding portion 14 in the upper frame 10, thereby improving watertightness.

In this way, the external flange sash 1 of this embodiment allows the installation of double-glazed glass 3 from both inside and outside, while blocking the path for water to enter the interior of the building, ensuring watertightness equivalent to that of conventional internal flange specifications, and also preventing light leakage.

The above describes embodiments of the building fixtures according to the present disclosure, but the present disclosure is not limited to the above embodiments.

For example, in the above embodiment, an external rib sash 1 is used with a composite frame 2 made of an aluminum frame (metal frame) and a resin frame, but this is not necessarily limited to a composite frame, and the configuration of the present invention can be applied to a sash made of only an aluminum frame, for example.

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 11, but there is no limitation to this height relationship. In short, it is sufficient that the height of the opening side end of at least one of the glass holding portions of the upper frame 10 and the lower frame 20 of the frame body, which faces the opening side of the frame body in the vertical direction Y of each glass holding portion, is different indoors and outdoors.

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 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 a rising portion that abuts against both side edges of the insulating glass 3. The rising portion has a fin portion that protrudes toward the insulating glass 3, and the fin portion contacts the side edge of the insulating glass 3 to provide an airtight seal.

In addition, the components in the above-described embodiments may be replaced with well-known components as appropriate without departing from the spirit of this disclosure.
