Description

The present invention relates to various composite fittings such as a sliding shoji and a single sliding shoji in which a shoji is housed in a frame having a metal frame and a resin frame.

Conventionally, for example, in a building such as a middle-rise or high-rise condominium, a sliding window described in Patent Document 1, for example, has been proposed. The sliding window made of a metal member such as an aluminum alloy described in Patent Document 1 has, for example, the configuration shown in FIG. 7. The aluminum alloy upper frame 101 is a resin bridge between a metal outdoor frame member 103 for accommodating an outer sash and an inner sash 102 and a metal indoor frame member 104 constituting an indoor side member of the frame body. It is connected by a material 105 to insulate it.

The upper frame 101 sandwiches the outer sash in the prospective direction between the outdoor frame member 103 and the intermediate rail 106 so that the outer sash can travel, and sandwiches the inner sash 102 between the intermediate rail 106 and the indoor frame member 104 so that the sash 102 can travel. There is. A resin bridge member 105 is installed in the sliding window in order to reduce dew condensation on the indoor frame member 104 forming the hanging piece on the indoor side. The bridge member 105 constitutes a heat insulating line that suppresses the transmission of external cold air into the room inside the upper frame 101.
Further, an airtight material 107 forming an airtight line is installed below the bridge material 105 between the upper frame 108 of the internal shoji 102 and the indoor frame member 104.

Japanese Patent No. 5621122

However, in the sliding window described in Patent Document 1 described above, cold air flows from the outside from the space between the intermediate rail and the upper stile 108 of the shoji 102, and receives cold air on the indoor side of the bridge member 105. Since dew condensation occurs on the inner and outer surfaces of the indoor frame member 104 on the indoor side, the heat insulating effect of the bridge member 105 is small. Further, since the bridge material 105 is fixed by caulking or the like, there is a drawback that the manufacturing cost is high. Moreover, since the indoor temperature is higher than that of the outside air, dew condensation is likely to occur on the surface of the indoor frame member 104 due to the temperature difference, and the dew condensation water on the indoor side and outdoor side surfaces of the indoor frame member 104 forming the hanging piece falls. There was a risk of

The present invention has been made in view of such a problem, and the surface of the hanging piece on the indoor side of the upper frame of the metal member is hard to condense, and even if dew condensation is formed, it is hard to be seen from the indoor side. The purpose is to provide composite fittings.

The composite fitting according to the present invention is a composite fitting in which a shoji is housed in a frame, and is a resin member arranged so as to cover at least an indoor surface of a hanging piece on the indoor side of the metal upper frame of the frame. A resin upper stile arranged on the indoor side of the metal upper stile of the shoji, and a fin portion made of a soft resin extending from the resin member toward the resin upper stile, and the hanging piece on the indoor side. An airtight material that extends from the portion to the outdoor side and abuts on the metal upper stile, or an airtight material that extends from the metal upper stile to the indoor side and abuts on the indoor side hanging piece portion is attached, and the hanging piece portion is attached. The metal upper stile is extended to a position facing the metal upper stile, and a plurality of hollow portions are formed between the metal upper stile and the resin upper stile .
Further, the fin portion may be softer than the resin member and the resin upper stile and elastically deformable.
Further, the fin portion may be in contact with the resin upper stile.

Further, it is preferable that a heat insulating layer is formed on the resin member .

Further, the heat insulating layer formed on the resin member is preferably formed of a hollow hollow portion .

Further, the airtight material is arranged on the outdoor side of the path through which the metal upper frame and the metal upper frame pass from indoors to outdoors, rather than the fin portion.
A space surrounded by the fin portion, the airtight material, the frame body, and the frame body of the shoji screen may be formed.

In the composite fitting according to the present invention, since the tip of the hanging piece on the indoor side and the surface on the indoor side of the metal upper frame are surrounded by a resin member, the surface temperature of the hanging piece is high and the heat insulating property is high, so that dew condensation can be reduced. At the same time, the cold air flowing in from the outdoor side can be blocked by the tip of the hanging piece.
Even if the surface of the hanging piece is exposed to cold air and dew condensation occurs, the tip of the hanging piece and the indoor surface are covered with a resin member, so that the dew condensation cannot be seen from the indoor side and the dew condensation water falls. Can be blocked by the tip of the resin member.

In FIGS. 1 and 3, the upper frame 2 of the frame body 5 is mainly formed of a metal upper frame 15, and a resin upper resin angle 16 having a substantially L-shaped cross section is connected to the indoor side surface thereof. The metal upper frame 15 has an outdoor side hanging piece portion 15b hanging from the outdoor side end portion, an intermediate rail portion 15c hanging from the middle portion, and an indoor side hanging from the indoor side end portion when viewed in the prospective direction of the base portion 15a forming the upper surface portion thereof. It has a hanging piece portion 15d.

An intermediate resin frame 17 having a substantially comb-shaped cross section is connected to the intermediate rail portion 15c on the indoor side thereof, and a substantially plate-shaped inner resin frame 18 is brought into contact with the outdoor side surface of the indoor side hanging piece portion 15d.

The indoor side hanging piece portion 15d made of metal is surrounded by indoor and outdoor surfaces a1 and a2 by an inner resin frame 18 and an upper resin angle 16.
Then, the outer sash 8 is held so as to be able to travel between the outdoor side hanging piece portion 15b and the intermediate rail portion 15c. The sash 7 is also movably held between the intermediate rail portion 15c and the indoor side hanging piece portion 15d.

Further, the lower frame 3 is mainly formed of a metal lower frame 19, an outer rail 20 is formed in the outdoor side region when viewed in the prospective direction of the metal lower frame 19, and an inner rail 21 is formed in the indoor side region. There is. A door roller (not shown) of the outer shoji 8 is mounted on the outer rail 20 so as to be able to run, and a door roller of the inner shoji 7 is mounted on the inner rail 21 so as to be able to run. It is possible to drive. At the indoor end of the metal lower frame 19, a resin lower resin angle 24 having a substantially L-shaped cross section is detachably installed between the metal lower frame 19 and the wooden frame 22 shown in FIG.

Further, in FIG. 2, the left and right vertical frames 4 are mainly formed of a metal vertical frame 25, and a resin vertical frame 26 having a plurality of hollow portions formed is connected to the indoor side of the metal vertical frame 25 on the left side, and the metal vertical frame 26 on the right side is connected. A side resin angle 27 having the same configuration as the upper resin angle 16 is connected to the indoor side of the frame 25.
Further, in the outer sash 8 and the inner sash 7, the four side stiles of the double glazing 9 are composed of an upper stile 10, a lower stile 11, and left and right vertical stiles 12 and 13. The double glazing 9 is supported by side edges on four sides by glass receiving portions 34 provided on the metal upper stile 10a, the metal lower stile 11a, and the left and right metal vertical stiles 12a and 13a, respectively, via a glazing channel. The indoor side of these metal stiles is covered with a resin upper stile 10b, a resin lower stile 11b, and left and right resin vertical stiles 12b and 13b, respectively.
The metal upper frame 15, the metal lower frame 19, the left and right metal vertical frames 25, the metal upper frame 10a, the metal lower frame 11a, and the left and right metal vertical frames 12a, 13a are made of, for example, an aluminum alloy.

Next, the airtight structure and the heat insulating structure between the metal upper frame 15 of the upper frame 2 and the upper stile 10 of the inner sash 7 will be described with reference to FIG. The metal indoor hanging piece 15d formed at the indoor end of the metal upper frame 15 hangs from the base 15a on the upper end side, and the receiving portion 35 is formed on the outdoor surface a2 of the lower end thereof. ing. A sealing member 36 made of, for example, an elastic aluminum alloy is fitted to the receiving portion 35 as an airtight material, and the tip thereof abuts on the surface portion 10aa of the metal upper stile 10a of the internal shoji 7 and seals airtightly. There is.
As the airtight material, an elastic member such as rubber may be used instead of a metal such as an aluminum alloy. An engagement receiving portion 37 is formed on the indoor side surface a1 of the indoor side hanging piece portion 15d.

Further, the resin upper resin angle 16 engaged with the indoor side hanging piece portion 15d of the metal upper frame 15 has a main body portion 16b provided with a stepped portion 16a, and the tip piece 16c thereof is made of metal. It abuts and covers the lower end of the inner hanging piece 15d.
Further, the upper resin angle 16 is locked so that the base portion abuts on the indoor side hanging piece portion 15d on the near end side of the stepped portion 16a and the tip side bends indoor side to engage with the engaging receiving portion 37. It has a piece 38. Further, the upper resin angle 16 extends upward from the main body portion 16b and bends or curves on the tip side to form an abutting piece 39 that abuts on the indoor side hanging piece portion 15d.
Further, the stepped portion 16a is connected or integrally formed with a fin portion 40 made of a soft resin extending toward the outdoor side, that is, the upper stile 10 of the internal sash 7. The soft resin of the fin portion 40 is softer than other resins and is formed so as to be elastically deformable, and is in contact with the upper stile 10 of the internal sash 7. When the sash 7 is run, the fin portion 40 is displaced in contact with the sash, and the airtight state is maintained.
The fin portion 40 may be formed of a relatively hard resin like other resins, and in this case, it is preferable that the fin portion 40 is in close contact with the upper stile 10 of the internal sash 7 in order to maintain airtightness. ..

On the other hand, in the upper stile 10 of the inner sash 7, for example, a vertically extending surface portion 10aa of the indoor side end portion of the metal upper stile 10a abuts on the sealing member 36 of the upper resin angle 16 and airtightly seals the metal upper stile 10a. The seal member 36 and the surface portion 10aa form an airtight line that prevents outside air from being ventilated indoors.
Further, the resin upper stile 10b connected to the metal upper stile 10a on the indoor side forms an indoor vertical portion 10ba in which the portion in contact with the fin portion 40 is, for example, flat. Further, a tapered portion 10bb that is inclined so as to widen toward the indoor side is formed in the lower portion thereof, and a concave portion 10bb having a protrusion at the tip thereof is formed on the lower portion thereof.
The resin upper stile 10b may be formed of a soft resin so as not to come into contact with the upper frame 2 and be damaged when the inner sash 7 is removed from the frame body 5 to the indoor side.

Therefore, the stepped portion 16a of the upper resin angle 16, the tip piece 16c, and the fin portion 40 form a heat insulating layer 42 having a substantially U-shaped cross section to insulate the cold air transmitted from the outdoor side, and form a heat insulating line. To do. Further, even when the dew condensation adhering to the surfaces a1 and a2 of the indoor side hanging piece portion 15d falls along the surfaces a1 and a2, it can be held by the heat insulating layer 42. Further, even if the condensed water flows down from the heat insulating layer 42 to the resin upper stile 10b via the fin portion 40, it can be stored in the recess 10bc. In the heat insulating layer 42, the tip piece 16c is in non-contact with the upper stile 10 and the fin portion 40 is in contact with the upper stile 10, but the fin portion 40 may also be non-contact and may extend to a position close to the upper stile 10.
The resin upper stile 10b has a vertical surface or a surface that slightly inclines and descends from the recess 10bc, and a reverse tapered surface 10bd that inclines toward the double glazing 9 side. As a result, the condensed water that overflows the recess 10 bc flows along the resin upper stile 10 b and flows down from the reverse tapered surface 10 db onto the double glazing 9, so that it does not fall into the room.

In addition, in FIGS. 1 and 3, a sealing member 36A is also installed on the outdoor side of the intermediate rail portion 15c of the metal upper frame 15 of the upper frame 2 as an airtight material that abuts on the upper stile 10 of the outer sash 8, and is an airtight line. Consists of.
Further, the intermediate resin frame 17 connected to the indoor side of the intermediate rail portion 15c has the same configuration as the upper resin angle 16 attached to the indoor side hanging piece portion 15d described above. That is, the intermediate resin frame 17 connected to the indoor side of the intermediate rail portion 15c also surrounds the indoor side and the tip by the tip piece 17a abutting on the lower end portion of the intermediate rail portion 15c. The tip piece 17a of the intermediate resin frame 17, the inclined step portion, and the fin portion 40A made of soft resin form a heat insulating layer 42A having a substantially U-shaped cross section, and the heat insulating layer 42A constitutes a heat insulating line.
Further, in the resin upper stile 10b attached to the metal upper stile 10a of the outer sash 8, the indoor vertical portion 10ba, the tapered portion 10bb, and the concave portion with which the fin portion 40A abuts, similarly to the resin upper stile 10b provided on the inner sash 7. It has 10 bc, a surface that descends vertically or slightly inclined from the recess 10 bc, and an inverted tapered surface 10 bd.

Next, the lower resin angle 24 provided between the metal lower frame 19 of the lower frame 3 and the frame 22 will be described with reference to FIGS. 4 and 5.
The lower resin angle 24 has substantially the same configuration as the upper resin angle 16 described above. The metal lower stile 11a forms a lower frame 11aa that extends further below the engagement portion with the resin lower stile 11b at the indoor side end and bends in a substantially L shape. The indoor side wall surface 19a provided at the indoor side end of the metal lower frame 19 extends in the vertical direction and horizontally overlaps with the lower frame 11aa at the upper end portion, and the receiving portion 19b is formed on the outdoor side thereof. .. An engagement receiving portion 19c is formed on the indoor side of the indoor side wall surface 19a.
A sealing member 44 made of an elastic member made of aluminum alloy or rubber, which is fitted to the receiving portion 19b, is in contact with the lower frame 11aa to form an airtight material that prevents cold air from being ventilated to the indoor side. ..

Further, a small gap is formed between the indoor side wall surface 19a of the metal lower frame 19 and the frame 22, and a lower resin angle 24 is installed above the gap. The lower resin angle 24 is formed in a substantially flat plate shape, the base thereof is fixed to the step portion of the frame 22 by a fixing bolt 45, and the tip is placed on the upper end of the indoor side wall surface 19a to form an elastic soft material at the tip. The resin fin portion 46 is in contact with the lower frame 11aa provided on the metal lower frame 19.
The lower resin angle 24 is formed with a locking piece 48 that can be engaged with the engaging receiving portion 19c toward the lower side in the gap in the vicinity of the fin portion 46, and further downward on the frame 22 side in the gap. The contact piece 49 that extends and bends or curves on the tip side to abut on the indoor side wall surface 19a of the metal lower frame 19 is formed.
Therefore, the lower resin angle 24 is locked to the frame 22 and the engaging receiving portion 19c of the metal lower frame 19 by the fixing bolt 45 and the locking piece 48. Moreover, since the locking piece 48 is provided on the indoor side of the indoor side wall surface 19a, when the fixing bolt 45 is removed from the frame 22 and the tip of the lower resin angle 24 on the fin portion 46 side is pulled up, the contact piece 49 becomes elastic. By deforming, the locking piece 48 is disengaged from the engaging receiving portion 19c and can be removed. Therefore, the lower resin angle 24 can be attached and detached and replaced when it is damaged.
Further, the lower resin angle 24 can also be detached and replaced by elastically deforming the contact piece 39 when the tip piece 16c is pulled down and disengaging the locking piece 38 from the engaging receiving portion 37.

The sliding window 1 according to the first embodiment has the above-mentioned airtight and heat insulating structure, and the operation thereof will be described next. It is assumed that the sliding window 1 shown in FIGS. 1 and 2 is installed in a building such as a middle floor or a high floor. In the closed state of the outer sash 8 and the inner sash 7 of the sliding window 1, on the inner sash 7 side, the low temperature outside air is sent to the intermediate rail portion 15c of the upper frame 2 and the intermediate resin frame 17 and the upper stile 10 of the inner sash 7. It flows through the space between them and flows into the indoor side.
The outside air flows to the indoor side hanging piece 15d side through the gap between the metal upper frame 15 on the indoor side and the upper stile 10 of the shoji sash 7. Here, the airtight seal can be achieved by the sealing member 36 provided on the indoor side hanging piece portion 15d abutting on the metal upper stile 10a of the internal sash 7. This airtight line prevents outside air from flowing beyond the seal member 36 to the indoor side.

Further, a part of the outside air flowing between the indoor side hanging piece 15d and the upper stile 10 of the shoji 7 cools the indoor side hanging piece 15d and transmits the cold air downward. Even in this case, since the heat insulating layer 42 having a substantially U-shaped cross section is formed at the tip of the upper resin angle 16, low temperature transmission and inflow of cold air to the indoor side are prevented through the upper resin angle 16. Alternatively, it can be reduced.

Further, since the indoor side hanging piece portion 15d is surrounded by the tip and both sides a1 and a2 by the inner resin frame 18 on the outdoor side and the upper resin angle 16 on the indoor side, the surface temperature is high and dew condensation can be suppressed. In particular, the tip of the indoor hanging piece 15d and the indoor side exhibit a heat insulating effect because the heat insulating layer 42 of the upper resin angle 16 and the contact piece 39 cover the indoor surface a1 of the indoor hanging piece 15d. Therefore, it is possible to suppress the transmission of cold air indoors and reduce the occurrence of dew condensation on the indoor side surface a1 of the indoor side hanging piece portion 15d.
However, when some of the cold air wraps around the inner resin frame 18 and comes into contact with the indoor side hanging piece portion 15d, dew condensation may occur on the inner and outer surfaces a1 and a2 of the indoor side hanging piece portion 15d. Even in this case, the indoor side hanging piece portion 15d is covered with the contact piece 39 of the upper resin angle 16 and is not exposed to the indoor side, so that an indoor person cannot see it.

Then, even if the indoor side hanging piece portion 15d condenses due to the low temperature and a part of the dew condensation water becomes water droplets and flows downward, the dew condensation water is received by the fin portion 40 of the heat insulating layer 42 having a U-shaped cross section. Water can be retained and the fall of condensed water can be suppressed.
Further, when the condensed water retained in the heat insulating layer 42 flows downward through the fin portion 40 due to its weight, it flows from the indoor vertical portion 10ba of the resin upper stile 10b to the tapered portion 10bb and has a protrusion. It is stored in 10 bc. This also prevents the condensed water from falling on the indoor side.
Further, even if the condensed water overflows from the concave portion 10 bc, the condensed water does not fall to the floor surface or the like, and the double glazing 9 is passed from the substantially vertical surface of the concave portion 10 bc of the resin upper stile 10 b via the reverse tapered surface 10 db. It runs down to the surface of. Therefore, even if a part of the condensed water flows downward from the resin upper stile 10b through the double glazing 9 on the indoor side of the shoji sash 7, it is not noticeable.

Further, even when low-temperature outside air enters between the outdoor side hanging piece portion 15b of the metal upper frame 15 and the upper stile 10 of the outer sash 8, heat insulation can be performed as in the case of the inner sash 7. That is, the upper stile 10 of the inner sash 7 is provided by the seal member 36A which is brought into contact between the intermediate rail portion 15c of the metal upper frame 15 provided on the indoor side of the outer sash 8 and the metal upper stile 10a of the outer sash 8. Form an airtight line between them. Therefore, the outside air is blocked from entering the indoor side by the seal member 36A.

Further, the intermediate resin frame 17 is covered by the tip piece 17a in contact with the tip of the intermediate rail portion 15c, and is provided with a heat insulating layer 42A having a substantially U-shaped cross section by the tip piece 17a and the fin portion 40A. Can reduce or prevent transmission to.
Moreover, in addition to the heat insulating layer 42A, the indoor surface of the intermediate rail portion 15c is surrounded by the intermediate resin frame 17, so that the surface temperature can be improved and dew condensation due to cold air can be prevented. Even if a slight amount of dew condensation occurs, it cannot be seen from the room because it is covered with the intermediate resin frame 17 and is not exposed to the indoor side. When dew condensation occurs on the outdoor side surface of the intermediate rail portion 15c, even if the dew condensation water falls, the dew condensation water can be stored in the heat insulating layer 42A, so that the fall can be prevented.

Further, even when a part of the dew condensation water stored in the heat insulating layer 42A drops from the fin portion 40A, the dew condensation water that flows down can be similarly stored in the recess 10bc of the resin upper stile 10b, and further along the double glazing 9. Can be washed away.
By locking the upper resin angle 16 to the indoor side hanging piece portion 15d and locking the intermediate resin frame 17 to the intermediate rail portion 15c, the upper resin angle 16 and the intermediate resin frame 17 expand and contract due to heat. Can be suppressed.

As described above, according to the sliding window 1 according to the present embodiment, an airtight line is provided by the seal member 36 between the indoor side hanging piece portion 15d and the upper stile 10 of the internal sash 7, and further on the indoor side of the airtight line. Since the heat insulating line by the heat insulating layer 42 is provided, the heat insulating effect of preventing the cold air on the outdoor side from being transmitted to the indoor side and blocking the cold outside air by the heat insulating layer 42 is high.
Further, since the tip of the indoor side hanging piece 15d and both indoor and outdoor sides are surrounded by the upper resin angle 16, the inner resin frame 18, and the heat insulating layer 42, the surface temperature of the indoor side hanging piece 15d becomes high, and the indoor side hanging piece 15d rises. Condensation is unlikely to occur on the inner and outer surfaces of one part 15d, and even if dew condensation occurs, it can be made invisible from the indoor side, and it looks good.

Moreover, even if the dew condensation generated on the indoor / outdoor surface of the indoor side hanging piece portion 15d flows down, it can be stored by the heat insulating layer 42 provided on the upper resin angle 16 and the dew condensation water can be suppressed from flowing down. Further, even if the condensed water flows down from the fin portion 40 of the heat insulating layer 42, the tapered portion 10bb formed on the resin upper stile 10b of the upper stile 10 can flow and be stored in the recess 10bc, and further, along the shape of the resin upper stile 10b. Since it can flow down to the surface of the double glazing 9, it is possible to reliably prevent the dew condensation water from falling.
Further, since a resin sealing material is not used for the metal upper frame 15 in order to prevent heat transfer of low-temperature outside air in the metal upper frame 15, caulking and fixing are not required, and assembly is easy and inexpensive.
Further, since the upper frame 10 of the outer sash 8, the intermediate rail portion 15c of the metal upper frame 15, and the intermediate resin frame 17 have the same configurations, the same effects can be obtained.

The sliding window 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention. Hereinafter, other embodiments and modifications of the present invention will be described, but the same or similar parts and members described in the above-described embodiments will be described by using the same reference numerals.

Next, the heat insulating structure of the sliding window 1A according to the second embodiment of the present invention will be described with reference to FIG.
The sliding window 1A according to the second embodiment has substantially the same configuration as the sliding window 1 according to the first embodiment. The difference is that in the sliding window 1A according to the second embodiment, a hollow hollow covered with resin is used instead of the heat insulating layer 42 having a substantially U-shaped cross section provided in the upper resin angle 16 according to the first embodiment. A heat insulating layer 50 having a shape is formed. Since the heat insulating layer 50 does not have an opening, the function of storing the falling dew condensation water cannot be obtained, but the heat insulating performance is further improved because the hollow hollow portion is formed.

In the present embodiment, the shapes of the heat insulating layers 42 and 50 in the upper resin angle 16 may be any shape as long as they can exert a heat insulating effect, and other appropriate configurations can be adopted. For example, the heat insulating layers 42 and 50 may have a solid cross-sectional square shape or other cross-sectional shape in which the hollow portion is filled with resin, or the upper stile 10 may be used instead of the U-shaped cross section or the hollow hollow portion shape. It may have a substantially Z-shaped cross-sectional shape facing the resin upper stile 10b.
Further, the resin tip pieces 16c and 17a forming the heat insulating layers 42 and 50, the fin portions 40 and 40A of the soft resin, or the hard resin form the resin piece portion.
Further, in each of the above-described embodiments, the upper resin angle 16 and the inner resin frame 18 are provided on the indoor side and the outdoor side of the indoor side hanging piece portion 15d as a heat insulating structure to reduce the surface temperature of the indoor side hanging piece portion 15d. Although dew condensation is suppressed, the inner resin frame 18 does not necessarily have to be installed.

Further, in each of the above-described embodiments, the sealing members 36 and 36A forming the airtight material are provided on the indoor side hanging piece portion 15d and the receiving portion 35 of the intermediate rail portion 15c so as to come into contact with the upper stiles 10 of the inner and outer shoji sashes 7 and 8. However, on the contrary, the sealing members 36 and 36A may be attached to the upper stile 10 so as to be brought into contact with the indoor side hanging piece portion 15d and the intermediate rail portion 15c for sealing.
Further, in the heat insulating layers 42 and 42A, the fin portions 40 and 40A may not be provided.
In the present invention, the upper resin angle 16, the inner resin frame 18, and the intermediate resin frame 17 constitute a resin member. Further, the present invention is not limited to the sliding window 1, and can be applied to various composite fittings such as a single sliding shoji.
