Description

TECHNICAL FIELD The present invention relates to various composite fittings such as double sliding windows and FIX windows in which shoji and glass panels are housed in a frame having a metal frame and a resin frame.

2. Description of the Related Art Conventionally, a double sliding window and the like described in Patent Document 1, for example, have been proposed as composite fittings including a frame body in which a metal such as aluminum and resin are connected and a shoji. In this double sliding window, the outer shoji and inner shoji are housed in a frame, and the side edges of each side of the double-glazed glass of each shoji are covered with glazing channels, and the upper frame, lower frame, left and right It is pressed and held by a frame composed of vertical frames. Glass grooves of metal stiles are attached to the outside of the glazing channel covering the side edges of the double glazing to hold the glazing channel.

The glass groove of the metal frame extends at its outdoor side and presses the vicinity of the tip fin of the rising portion of the glazing channel, and the indoor side contacts the lower portion of the rising portion of the glazing channel. Moreover, on the indoor side, a resin frame covering the metal frame is connected to ensure heat insulation and design. .

JP 2013-67979 A

However, in such a double sliding window, the resin frame heat-shrinks due to changes in the outside air temperature, etc., so the pressing position of the rising portion of the glazing channel by the resin frame on the indoor side against the multi-layered glass shifts, creating a gap. Airtightness is reduced. Then, there is a risk that cold air, sound, etc., from the outdoor side may enter through the gap between the glazing channel and the glazing channel on the indoor side and the gap between the glazing channel and the resin frame of the double-glazed glass on the indoor side.
In addition, if a gap occurs in the joint between the vertical resin frame and the lower resin frame due to heat shrinkage, outside air and sound will flow in from the gap between the outdoor glazing channel and the glass panel through the gap in the joint. There was a drawback that outside air and sound sometimes flowed into the room through the gap between the inner glazing channel and the resin frame.

The present invention has been made in view of such problems, and in a composite fitting formed by connecting a metal member and a resin member, even if the resin member thermally shrinks, the glass panel and the composite member To provide a composite fitting with improved airtightness and heat insulation.

A composite fitting according to the present invention is a composite fitting in which a glass panel is housed in a frame-shaped member assembled from composite members in which a metal member and a resin member are respectively connected. It is characterized by comprising a stopper, a panel receiving portion made of a metal member that presses and airtightly holds the sealing members on the outdoor side and the indoor side, and a resin member that covers the indoor side portion of the metal member.
According to the composite fitting according to the present invention, in the composite member of the composite fitting that accommodates the glass panel, by pressing the sealing material provided on the peripheral edge portion of the surface of the glass panel with the panel receiving portion of the metal member, the outside temperature can be reduced. Even if the resin member thermally shrinks due to changes, etc., the metal member does not thermally shrink, so airtightness is achieved by preventing the flow of indoor and outdoor air and sound between the glass panel and the panel receiving portion of the metal member that sandwiches the sealing material. can ensure the integrity.

In addition, it is preferable that the panel receiving portion of the metal member has a pressing portion that presses the sealing material, and that the pressing portion is formed continuously along the side edge portion of the entire circumference of the glass panel. .
Thereby, airtightness can be ensured over the entire circumference of the side edge of the glass panel.

In addition, the sealing material that presses the glass panel has a protrusion that protrudes toward the indoor side, and the resin member has a front-side protrusion that presses the sealing material. It is preferable that the pressing portion of the receiving portion is engaged with the protrusion of the sealing material with the front protrusion of the resin member interposed therebetween.
In this case, even if the resin member thermally shrinks, the front protrusion of the resin member is sandwiched between the pressing portion of the panel receiving portion and the protrusion of the sealing material, thereby suppressing thermal contraction of the resin member. As a result, it is possible to suppress the exposure of the metal member to the indoor side.

In addition, a first locking portion is provided in the vicinity of the pressing portion of the panel receiving portion of the metal member, and a second locking portion that engages with the first locking portion is provided in the vicinity of the front projection of the resin member. may
On the indoor side of the composite fittings, the protrusion of the sealing material and the pressing portion of the panel receiving portion press and hold the front side protrusion of the resin member, and the panel receiving portion of the metal member and the resin member further press and hold the front side protrusion. Since the locking portion and the second locking portion can be engaged and held, even if the resin member tries to thermally shrink, the double engagement structure prevents the metal member from being exposed indoors more reliably. can.

In the composite fitting according to the present invention, the metal member is a metal frame, the resin member is a resin frame, and the frame-shaped member in which the glass panel is housed is a shoji. Airtightness on the indoor side can be reliably realized.

In the composite fitting according to the present invention, the metal member is a metal frame, the resin member is a resin frame, and the frame-shaped member in which the glass panel is housed is the FIX window. Airtightness on the indoor side can be reliably realized by

According to the composite fittings of the present invention, the glass panel is housed in the frame-shaped member made of the composite member connecting the metal member and the resin member, and the sealing material provided on the peripheral edge of the surface of the glass panel is a panel support for the metal member. Since the parts are pressed and kept airtight, it is possible to ensure airtightness between the outside and the inside where the glass panel of the composite fitting is sandwiched.
Moreover, since the indoor side portion of the metal member is covered with the resin member, there is an advantage that heat insulation can be ensured and the design of the exterior is high.

Similarly, in the left and right vertical frames 12 and 13 shown in FIG. 2, the resin vertical frames 12b and 13b are connected to the indoor side of the metal vertical frames 12a and 13a provided on the outdoor side. These upper metal frame 10a, lower metal frame 11a, and vertical metal frames 12a and 13a are made of aluminum alloy or the like.
Further, in the outer shoji 8, the upper frame 10, the lower frame 11, and the left and right vertical frames 12 and 13 have the same configuration, and the same reference numerals are used to omit the description. The vertical frame 12 is the door frame, and the vertical frame 13 is the dining room frame.
A door roller 17 to be placed on the inner rail 16 is installed under the metal lower frame 11a of the inner shoji 7, and a door roller 14 to be placed on the outer rail 15 is installed under the metal lower frame 11a of the outer shoji 8. ing.

Next, the structure of the lower frame 11 shown in FIG. 3 will be representatively described for the indoor/outdoor airtight structure and the airtight line of the double glazing 9 and the frame portion of the double sliding window 1 according to the embodiment.
In the inner shoji 7 shown in FIGS. 1 and 3, the multi-layered glass 9 supported by the inner shoji 7 has spacers 21 interposed at the ends of the four sides between the two glass panels 20, respectively. The four side edges of the double glazing 9 are surrounded continuously over the entire periphery by a glazing channel 22 having a substantially U-shaped cross section.
The glazing channel 22 is formed of a base portion 22a that abuts on the end surface of the double glazing 9 and rising portions 22b that abut on both side edges (peripheral portions). A portion 24 and a tip fin portion 25 at the tip portion are formed. Both sides of the double glazing 9 and the glazing channel 22 are hermetically sealed indoors and outdoors by the fins 23 and the tip fins 25 .

The metal lower frame 11a of the lower frame 11 has a panel receiving portion 26 having a substantially U-shaped cross section so as to surround the glazing channel 22, and a door roller holding a door roller 17 below the panel receiving portion 26. The holding part 27 is connected.
In the panel receiving portion 26 of the metal lower frame 11a, the side portions 26b on the outdoor side and the indoor side of the receiving portion 26a facing the base portion 22a of the glazing channel 22 extend upward, respectively, and are formed on the rising portion 22b of the glazing channel 22. A thick pressing portion 26c is formed in contact with the flat portion 24 and the protrusion 25a of the tip fin portion 25. As shown in FIG. Moreover, on the indoor side, the front side protrusion 28 of the resin lower frame 11b is fitted between the pressing part 26c and the protrusion 25a, but the front side protrusion 28 may not be sandwiched. As a result, the rising portion 22b on the indoor side is pressed against the glass panel 20 by the pressing portion 26c of the panel receiving portion 26 and the front projection portion 28. As shown in FIG.
Therefore, both raised portions 22b of the glazing channel 22 covering one end portion of the double glazing 9 are pressed and supported by the panel receiving portion 26 of the metal lower frame 11a. Moreover, a space is formed between the base portion 22 a of the glazing channel 22 and the receiving portion 26 a of the panel receiving portion 26 .

A resin lower stile 11b provided on the indoor side of the metal lower stile 11a is installed so as to cover the indoor side portion of the metal lower stile 11a and is connected to the metal lower stile 11a. The front protrusion 28 of the resin lower frame 11b is formed by the protrusion 25a of the tip fin portion 25 and the pressing portion 26c formed in the panel receiving portion 26 of the metal lower frame 11a at the rising portion 22b installed on the indoor side of the glazing channel 22. is sandwiched between
Therefore, the pressing portion 26c on the indoor side of the panel receiving portion 26 presses the projecting portion 25a of the glazing channel 22 via the front projecting portion 28 of the resin lower frame 11b. A side portion 26b on the indoor side of the panel receiving portion 26 is branched in the vicinity of the pressing portion 26c to form a locking receiving portion 29 bent in a substantially hook shape. A substantially L-shaped locking portion 28 a branched from the front projection 28 of the resin lower frame 11 b is engaged with a locking receiving portion 29 .
The combined structure of the glazing channel 22, the metal lower frame 11a, and the resin lower frame 11b covering the end and side edges of the multi-layered glass 9 is called a resin heat shrinkage prevention structure 31A.

In the resin heat shrinkage prevention structure 31, the resin lower frame 11b on the indoor side has a front protrusion 28 pressed and held between the pressing portion 26c of the panel receiving portion 26 of the metal lower frame 11a and the protrusion 25a of the glazing channel 22. Moreover, the locking receiving portion 29 provided on the side portion 26b of the panel receiving portion 26 and the locking portion 28a of the front projection 28 are engaged with each other to fix the panel receiving portion 26. As shown in FIG.
Therefore, even if the resin lower frame 11b expands and contracts due to heat, the front projection 28 and the locking portion 28a do not come off or shift from the metal lower frame 11a. In addition, although the front side protrusion 28 of the resin lower frame 11b is engaged with the side portion 26b of the panel receiving portion 26 at two locations, it may be engaged at one location.
The upper frame 10 also has a resin heat shrinkage preventing structure 31A having the same joint structure.

2 and 4 are horizontal cross-sectional views of main parts showing the connecting structure between the left and right vertical frames 12, 13 and the double glazing 9 of the inner shoji 7 and the outer shoji 8. As shown in FIG. The resin heat shrinkage preventing structure 31B on the left and right vertical frames 12 and 13 of the inner shoji 7 basically has the same structure as the resin heat shrinkage preventing structure 31A provided on the lower frame 11. As shown in FIG.
As a difference, in the vertical frame 12 on the door end side of the inner shoji 7 shown in FIG. A pressing portion 33 having a substantially U-shape and further bent at the tip is formed so as to press the . The front protrusion 28 of the vertical resin frame 12b is sandwiched and engaged between the pressing portion 33 and the protrusion 25a of the tip fin portion 25 of the glazing channel 22 to press the rising portion 22b. Moreover, it has a configuration in which a locking portion 28 a branched from the front projection 28 is engaged with the inside of the pressing portion 33 .
The metal vertical frames 12a, 13a and the resin vertical frames 12b, 13b of the vertical frames 12, 13 of the outer shoji 8 also have the same resin heat shrinkage preventing structure 31B.

In the vertical frame 13 on the meeting side of the inner shoji 7 shown in FIGS. Reference numeral 26b designates a pressing member 35 provided at the rising portion 22b of the glazing channel 22, which is divided into approximately two forks. are doing. The leading end of the projecting portion 28 of the vertical resin frame 13b is sandwiched between the tip of the pressing portion 35a of the pressing member 35 and the projecting portion 25a of the tip fin portion 25 to press the rising portion 22b of the glazing channel 22. . A locking portion 28 a branched from the front projection 28 is configured to engage with a locking receiving portion 35 b of the pressing member 35 .

In addition, in the inner shoji 7 and the outer shoji 8 of the above-described embodiment, three types of resin heat shrinkage prevention structures 31A, 31B, and 31C having different shapes of bent portions provided on the side portion 26b of the panel receiving portion 26 are provided. However, any one type may be adopted.
The glazing channel 22 made of an elastic material such as rubber and the panel receiving portion 26 made of aluminum alloy are formed continuously at the ends of the four sides of the double glazing 9, and the resin heat shrinkage preventing structures 31A, 31B, 31C. ensures airtightness indoors and outdoors.

FIG. 5 is a partial perspective view showing the connection structure between the vertical frame 12 and the lower frame 11 on the door edge side of the inner shoji 7. As shown in FIG. A lap allowance (not shown) was provided at the end of the metal lower frame 11a and fitted to the vertical metal frame 12a. The lap allowance (not shown) of the metal lower stile 11a is fitted to the resin lower stile 11b on the indoor side of the metal vertical stile 12a. combined.
With such a fitting structure, even if the resin lower frame 11b and the resin vertical frame 12b are thermally shrunk, the resin thermal contraction prevention structures 31, 31A, and 31B prevent the thermal contraction. and the resin vertical frame 12b to prevent the inner metal lower frame 11a and the metal vertical frame 12a from being exposed. The same applies to the fitting structure between the lower frame 11 and the vertical frame 13 on the meeting side. Moreover, the same structure is adopted also in the outside shoji 8. As shown in FIG.

As shown in FIGS. 1 and 3 , in the lower frame 11 of the outer shoji 8 , the outer rail 15 is formed in a stepped position one step lower than the inner rail 16 . is formed below a receiving plate 37 formed below the panel receiving portion 26 of the metal lower frame 11a. A fin portion 32 is provided at the outdoor end portion of the metal lower frame 3 a of the lower frame 3 so as to be able to contact the metal lower frame 11 a near the door roller holding portion 27 of the outer shoji 8 .
In addition, the metal upper frame 10a, the metal lower frame 11a, and the left and right metal vertical frames 12a and 13a forming each frame of the inner shoji 7 and the outer shoji 8 constitute metal frames, and the resin upper frame 10b, the resin lower frame 11b, The left and right vertical resin frames 12b and 13b constitute a resin frame.

The sliding window 1 according to this embodiment has the structure described above, and the operation thereof will be described below.
For example, in each lower frame 11 of the inner shoji 7 and the outer shoji 8 shown in FIGS. The pressing portions 26c of the side portions 26b formed on the panel receiving portion 26 of the frame 11a press. Moreover, in the rising portion 22b of the glazing channel 22 on the indoor side, the projecting portion 25a on the opposite side of the tip fin portion 25 is pushed by the pressing portion 26c of the both side portions 26b formed on the panel receiving portion 26, and the resin lower frame 11b is pushed forward. The front projection 28 also presses the rising portion 22b.

Therefore, even if the resin lower frame 11b thermally shrinks due to changes in the temperature of the outside air, the metal lower frame 11a made of aluminum or the like does not thermally shrink. On the indoor side, the rising portion 22b of the glazing channel 22 is airtightly pressed against the double glazing 9 by the pressing portion 26c of the panel receiving portion 26 and the front projection 28, so that the heat shrinkage of the resin lower frame 11b is suppressed. , does not create gaps. Therefore, outside air, sound, etc. do not leak into the indoor side from between the multi-layered glass 9, the rising portion 22b of the glazing channel 22 on the indoor side, and the resin lower frame 11b.
In addition, not only the resin heat shrinkage prevention structure 31A in the inner shoji 7 and the outer shoji 8, but also the resin heat shrinkage prevention structures 31B and 31C, the glazing channel 22 and the resin upper frame 10b covering both side edges of the double glazing 9. , and the left and right resin vertical frames 12b and 13b, airtightness can be maintained.

Moreover, the indoor-side tip projections 28 of the lower resin frame 11b, the upper resin frame 10b, and the left and right vertical resin frames 12b and 13b are the pressing portions of the lower metal frame 11a, the upper metal frame 10a, and the left and right vertical metal frames 13a. 26c and the projecting portion 25a of the tip fin portion 25, and the locking receiving portion 29 of the side portion 26b and the locking portion 28a of the front side projecting portion 28 are engaged with each other. 11b, the upper resin frame 10b, and the left and right vertical resin frames 12b and 13b can be prevented from thermal contraction.
Therefore, heat shrinkage of the lower resin frame 11b, the upper resin frame 10b, and the left and right vertical resin frames 12b, 13b is suppressed not only in the lateral direction but also in the longitudinal direction. Even if the lower resin frame 11b, the upper resin frame 10b, and the left and right vertical resin frames 12b and 13b are slightly thermally shrunk in the longitudinal direction, creating gaps between the resin frames and exposing the metal frames, airtightness is not guaranteed. does not affect sexuality.

As described above, the sliding window 1 according to this embodiment has the following effects.
(1) The rising portions 22b of the glazing channel 22 covering the four side edges of the double glazing 9 are pressed by the pressing portions 26c provided on the side portions 26b of the panel receiving portion 26 of the metal frame to be kept airtight. Even if the resin frame covering the metal frame is thermally shrunk, the airtightness between the multi-layered glass 9 and the side portion 26b of the panel receiving portion 26 can be ensured.
(2) The pressing portion 26c of the side portion 26b on the indoor side of the panel receiving portion 26 presses the projecting portion 25a of the glazing channel 22 with the projecting portion 28 on the front side of the resin frame in between to ensure airtightness. By covering the metal frame with the resin frame, the design can be improved.

(3) Moreover, the pressing portion 26c on the indoor side of the panel receiving portion 26 clamps the front-side protrusion 28 of the resin frame between the protrusion 25a of the tip fin portion 25 and the rising portion 22b of the panel receiving portion 26. and the locking portion 28a of the front projection 28 of the resin frame are held in an engaged state, the resin frame is prevented from thermally shrinking, and the metal frame is exposed to the indoor side. can be prevented.
Therefore, even if the lower resin frame 11b, the upper resin frame 10b, and the like contract in the longitudinal direction due to heat shrinkage and a gap is generated at the corner portion where the left and right resin vertical frames 12b and 13b are joined, the indoor and outdoor airtightness is maintained. without compromising.

In addition, the composite fittings according to the present invention are not limited to the double sliding window 1 according to the first embodiment described above, and appropriate modifications and replacements are possible without departing from the gist of the present invention.
Other embodiments and modifications of the present invention will be described below. Parts and members that are the same as or similar to those described in the above embodiments will be described using the same reference numerals.

For example, FIG. 6 shows a double sliding window 1A according to the second embodiment of the present invention, and FIG.
In the double sliding window 1A according to the second embodiment, the glazing channel 22 is not installed on the side edge of the double glazing 9, and the sealing material 40 is used. That is, the metal lower frame 11a of the lower frame 11 of the inner shoji 7 is formed with a panel receiving portion 26 having a substantially U-shaped cross section so as to cover the side edge portion of the multi-layered glass 9. As shown in FIG.

An elastic material 41 such as a sponge is installed between the inner and outer side surfaces of the double glazing 9 and the side portions 26b of the panel receiving portion 26, so that the inner and outer side edges of the double glazing 9 and the side portions 26b of the panel receiving portion 26 are separated. A sealing material 40 is filled in the space between and solidified. The sealing material 40 has an irregular shape or a regular shape, and can be made of, for example, silicone, modified silicone, urethane, butyl, or the like.

Moreover, the upper surface of the pressing portion 26c (abutting portion) of the side portion 26b provided on the indoor side of the metal lower rail 11a is provided with the front projection 28 formed at the upper end of the resin lower rail 11b on the sealing material 40 side. , and the tip is in contact with the upper portion of the pressing portion 26c. As a result, the pressure portion 26c on the indoor side of the panel receiving portion 26 and the front projection portion 28 press the sealing material 40 in an airtight manner.
On the indoor side of the panel receiving portion 26, a locking portion 28a branched from the front projection 28 is engaged with a locking receiving portion 29 formed on the side portion 26b of the panel receiving portion 26 and fixed.
On the other hand, the outdoor side portion 26b of the panel receiving portion 26 is filled with a sealing material 40 so that the upper end portion is substantially flush with the pressing portion 26c.

The sealing material 40 hermetically seals the space between the pressing portion 26c of the side portion 26b of the panel receiving portion 26 and the side edge portion of the double glazing 9. Since the portion 26b is covered with the sealing material 40 and the resin lower frame 11b and is not exposed to the outside, the design is excellent. Moreover, since the sealing material 40 has a higher heat insulating property than the panel receiving portion 26 made of aluminum, it is possible to improve not only the indoor/outdoor airtightness but also the heat insulating property.
Such a structure hermetically sealed with the sealing material 40 is formed not only on the lower frame 11 but also on the upper frame 10 and the left and right vertical frames 12 and 13 (not shown). Further, not only the inner shoji 7 but also the outer shoji 8 have the same structure.

Next, a FIX window 44 as a composite fitting according to a third embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. FIG. 7 shows a vertical cross-sectional view of a FIX window. A frame 5 installed at the opening of the building frame is formed into a quadrangular frame by an upper frame 2, a lower frame 3, and left and right vertical frames 4 (not shown). . In FIG. 7, an upper frame 2 is constructed by connecting a metal upper frame 2a provided on the outdoor side and a resin upper frame 2b provided on the indoor side, and a lower frame 3 is configured by connecting a metal lower frame 3a provided on the outdoor side and an indoor frame 2b. It is configured to be connected to the resin lower frame 3b provided inside. The left and right vertical frames 4 also have a similar configuration.
Then, for example, in the metal lower frame 3a shown in FIG. It extends to both side edges of the double glazing 9 .

One side portion 45b of the panel receiving portion 45, which rises on the outdoor side, is provided with a pressing portion 45c bent in a substantially L shape, for example, formed at the tip and a locking piece 45d formed at the base end thereof. . The other end of the glazing channel 46, one end of which is fitted between the pressing portion 45c and the locking piece 45d, is pressed against the surface of the double glazing 9 on the outdoor side.
On the other hand, the other side portion 45b, which rises on the indoor side of the panel receiving portion 45, has a pressing portion 45c formed at the distal end and bent into, for example, a substantially U-shaped cross section, and a locking receiving portion 49 formed on the opposite side at the proximal end side. and are provided. In addition, the upper portion of the pressing portion 45c made of aluminum alloy is in contact with the front side protrusion 48 extending from the lower resin frame 3b.

The pressing portion 45c and the front protrusion 48 are fitted and held in the recess 46a provided in the glazing channel 46, and the glazing channel 46 is pressed against the side edge of the double glazing 9 by the pressing portion 45c and the front protrusion 48. Airtightly pressed.
A locking portion 28a branched from a resin-made front-side protrusion 48 is fitted into a locking receiving portion 49 branching from a side portion 45b of the metal lower frame 3a and protruding to receive the resin lower frame 3b as a panel support. It is engaged with a side portion 45b of the portion 45 on the indoor side.

As a result, the glazing channel 46 hermetically seals the space between the multi-layer glass 9 and the pressing portion 45c of the panel receiving portion 45 of the metal lower frame 3a. Moreover, the pressing portion 45c of the side portion 45b of the panel receiving portion 45 made of aluminum is not thermally shrunk. Further, since the front protrusion 48 is sandwiched between the pressing portion 45c and the recess 46a of the glazing channel 46, and the locking receiving portion 49 and the locking portion 28a of the front protrusion 48 are engaged, Even if the resin lower frame 3b on the indoor side tries to thermally shrink due to a change in the outside air temperature or the like, the thermal shrinkage can be prevented. In addition, even if the lower resin frame 3b and the vertical resin frame try to thermally contract due to heat shrinkage at the corner portion of the joint portion between the lower resin frame 3b and the vertical resin frame, the thermal contraction can be suppressed. also does not affect the airtightness due to the sealing structure described above.
