Description

  The present invention relates to various composite fittings such as a sliding shoji and one-sided shoji with a shoji placed 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 apartment, a sliding window described in, for example, Patent Document 1 has been proposed. A sliding window made of a metal member such as an aluminum alloy described in Patent Document 1 has a configuration shown in FIG. 7, for example. The upper frame 101 made of an aluminum alloy is composed of a metal outdoor frame member 103 that accommodates an external shoji and an internal plinth 102, and a metal indoor frame member 104 that constitutes an indoor side member of the frame body. The material 105 is connected and insulated.

The upper frame 101 has an outer frame member sandwiched between the outdoor frame member 103 and the intermediate rail 106 in the expected direction, and the inner frame 102 is sandwiched between the intermediate rail 106 and the inner frame member 104 so as to be able to travel. Yes. The sliding window is provided with a resin bridge member 105 in order to reduce the condensation of the indoor frame member 104 that forms a hanging piece on the indoor side. The bridge member 105 constitutes a heat insulation line that suppresses external cold air from being transmitted into the room within the upper frame 101.
In addition, an airtight member 107 that constitutes an airtight line is installed below the bridge member 105 between the upper collar 108 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 space between the intermediate rail and the upper lid 108 of the inner shroud 102 from the outside, and receives cold air indoors from the bridge member 105. Since the dew condensation occurs on the inner and outer surfaces of the indoor frame member 104 on the indoor side, the heat insulating effect by the bridge member 105 is small. Further, since the bridge member 105 is fixed by caulking or the like, there is a drawback that the manufacturing cost is high. Moreover, because the temperature inside the room is higher than that of the outside air, condensation is likely to occur on the surface of the indoor frame member 104 due to the temperature difference, and the condensed water condensed on the indoor side and outdoor side surfaces of the indoor frame member 104 that forms a hanging piece falls. There was a risk.

  The present invention has been made in view of such a problem, and it is difficult to condense on the surface of the hanging part on the indoor side of the upper frame of the metal member, and even if dew condensation is difficult to see from the indoor side. The purpose is to provide composite joinery.

The composite joinery according to the present invention is a composite joinery in which a shoji is placed in the frame, and the tip of the indoor hanging piece and at least the surface on the indoor side of the metal upper frame of the frame are surrounded by a resin member. It is characterized by.
According to the present invention, the surface of the drooping piece is increased by the cold air flowing in from the outdoor side because the tip of the drooping piece on the indoor side of the metal upper frame and at least the surface on the indoor side are surrounded by the resin member. It is possible to reduce condensation on the hanging piece.
The resin member surrounding the surface of the hanging piece may be an indoor side surface or an indoor / outside surface. Since the surface temperature can be increased by enclosing the surfaces on both sides of the hanging piece with a resin member, the occurrence of condensation on the hanging piece due to cold air can be further suppressed.

Moreover, it is preferable that the heat insulation layer is formed in the resin member surrounding the front-end | tip of the hanging piece part on the indoor side.
By forming the heat insulating layer on the resin member surrounding the tip of the hanging piece, the heat insulating layer prevents cold air from being transmitted to the indoor side of the hanging piece, thereby preventing condensation.

Moreover, it is preferable that an airtight material extending from the hanging part on the indoor side to the outdoor side or an airtight material extending from the upper arm of the shoji to the indoor side is attached.
An airtight material extending from the hanging piece to the outdoor side, or an airtight material extending from the upper side of the shoji to the indoor side is attached to contact the shoji or the hanging piece, and this airtight material is provided on the outdoor side of the heat insulating layer. Thereby, it can further suppress that the cool air from the outdoors is transmitted to the indoor side.

Further, the heat insulating layer formed on the resin member may be formed of a resin piece portion having a substantially U-shaped cross section extending from the tip of the hanging piece portion to the upper arm of the inner limb.
Since the heat insulation layer is formed from a resin piece with a substantially U-shaped cross section from the tip of the hanging piece toward the upper arm of a shingles, etc., it can block the transmission of cold air, and condensation will occur on the hanging piece and flow down Even if it is received, it can be received and stored by a substantially U-shaped resin piece.
In addition, you may use a soft resin softer than the upper resin piece part for the lower resin piece part of the substantially U-shaped cross section.

Moreover, the heat insulation layer formed in the resin member may be formed by the hollow hollow part.
By forming the heat insulation layer at the hollow portion, the heat insulation effect is enhanced, and the transmission of cold air to the indoor side can be further reduced.

In the composite joinery according to the present invention, since the tip of the indoor hanging piece part and at least the indoor side surface of the metal upper frame are surrounded by the resin member, the surface temperature of the hanging piece part becomes high and the heat insulation is high, so that dew condensation can be reduced. At the same time, the cold air flowing from the outdoor side can be blocked at the tip of the hanging piece.
Also, even if the surface of the hanging piece is exposed to cold and dew condensation, the tip of the hanging piece and the indoor side surface are covered with a resin member, so condensation cannot be seen from the indoor side and the condensed water drops. Can be blocked by the tip of the resin member.

  The lower frame 3 is mainly formed of a metal lower frame 19, and an outer rail 20 is formed in the outdoor region as viewed in the prospective direction of the metal lower frame 19, and an inner rail 21 is formed in the indoor region. Yes. A door (not shown) of the outer shoji 8 is placed on the outer rail 20 so as to be able to travel, and the inner wheel 21 is placed so as to be able to run on the inner rail 21 so as to receive the loads of the outer shoji 8 and the inner shoji 7, respectively. Can travel. A lower resin angle 24 made of a resin having a substantially L-shaped cross section is detachably installed at an indoor side end portion of the metal lower frame 19 with a wooden frame 22 shown in FIG.

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 on the indoor side of the left metal vertical frame 25 is connected to the right metal vertical frame 25. A side resin angle 27 having the same configuration as that of the upper resin angle 16 is connected to the indoor side of the frame 25.
Further, the outer shoji 8 and the inner shoji 7 are configured such that the four sides of the double-glazed glass 9 are composed of an upper eyelid 10, a lower eyelid 11, and left and right longitudinal rods 12 and 13. The multi-layer glass 9 is supported at its four side edges by glass receiving portions 34 provided on the upper metal rod 10a, the lower metal rod 11a, and the left and right metal vertical rods 12a and 13a through glazing channels. The indoor side of these metal cages is covered with an upper resin cage 10b, a lower resin cage 11b, and left and right resin longitudinal rods 12b and 13b, respectively.
In addition, the metal upper frame 15, the metal lower frame 19, the left and right metal vertical frames 25, the metal upper rod 10a, the metal lower rod 11a, and the left and right metal vertical rods 12a and 13a are made of, for example, an aluminum alloy.

Next, an air-tight structure and a heat insulating structure between the metal upper frame 15 of the upper frame 2 and the upper collar 10 of the inner shoji 7 will be described with reference to FIG. A metal indoor side hanging piece 15d formed at the indoor side end of the metal upper frame 15 is suspended from the base 15a on the upper end side, and a receiving portion 35 is formed on the outdoor side surface a2 of the lower end. ing. The receiving portion 35 is fitted with, for example, an elastic aluminum alloy sealing member 36 as an airtight material, and the tip of the sealing portion 36 abuts on the surface portion 10aa of the metal upper collar 10a of the inner shroud 7 for airtight sealing. Yes.
An elastic member such as rubber may be used as the airtight material 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 15d.

The resin upper resin angle 16 engaged with the indoor side hanging piece 15d of the metal upper frame 15 has a main body 16b provided with a stepped portion 16a, and the tip piece 16c is made of a metal house. It covers and covers the lower end of the inner hanging piece 15d.
Further, the upper resin angle 16 has a base that is in contact with the indoor-side hanging piece 15d at the distal end in the vicinity of the stepped portion 16a, and a distal end that is bent toward the indoor side so that it can be engaged with the engagement 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 at the tip side to form an abutment piece 39 that abuts against the indoor side hanging piece 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 collar 10 of the inner shoji 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 collar 10 of the inner pouch 7. When the inner impeller 7 is caused to travel, it is displaced while the fin portion 40 is in contact therewith, and the airtight state is maintained.
In addition, the fin part 40 may be formed of a relatively hard resin like other resins, and in this case, it is preferable that the fin part 40 is close to the upper collar 10 of the inner limb 7 without contact. .

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

Therefore, the stepped portion 16a, the tip piece 16c, and the fin portion 40 of the upper resin angle 16 constitute a substantially U-shaped heat insulation layer 42 that insulates cold air transmitted from the outdoor side, and constitutes a heat insulation line. To do. Moreover, even when the dew condensation adhering to the surfaces a1 and a2 of the indoor side hanging piece 15d falls along the surfaces a1 and a2, it can be held by the heat insulating layer 42. Furthermore, even if the dew condensation water flows from the heat insulating layer 42 through the fin portion 40 to the resin upper tub 10b, it can be stored in the recess 10bc. In the heat insulating layer 42, the tip piece 16 c is not in contact with the upper flange 10 and the fin portion 40 is in contact, but the fin portion 40 may be in non-contact as long as it extends to a position close to the upper flange 10.
The resin upper ridge 10b has a vertical surface or a slightly inclined downward surface from the concave portion 10bc and an inversely tapered surface 10bd inclined to the multilayer glass 9 side. As a result, the condensed water overflowing the recess 10bc flows along the resin upper ridge 10b and flows down from the reverse tapered surface 10bd onto the multi-layer glass 9, so that it does not fall into the room.

1 and 3, a seal member 36A is 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 comes into contact with the upper arm 10 of the outer shroud 8. Is configured.
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 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 front end by the tip piece 17a coming into contact with the lower end portion of the intermediate rail portion 15c. A heat insulating layer 42A having a substantially U-shaped cross section is formed by the tip piece 17a of the intermediate resin frame 17, the inclined stepped portion, and the fin portion 40A made of a soft resin, and the heat insulating layer 42A constitutes a heat insulating line.
In addition, in the resin upper collar 10b attached to the metal upper collar 10a of the external shoji 8, the indoor vertical section 10ba, the taper section 10bb, and the concave portion with which the fin section 40A abuts, similar to the resin upper collar 10b provided on the inner shoji 7, 10bc, a surface descending vertically or slightly inclined from the recess 10bc, and a reverse tapered surface 10bd.

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.
The lower resin angle 24 has substantially the same configuration as the upper resin angle 16 described above. The metal lower collar 11a forms a lower frame 11aa which extends further below the engagement portion with the resin lower collar 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 portion of the metal lower frame 19 extends in the vertical direction, overlaps the lower frame 11aa in the horizontal direction at the upper end portion, and a receiving portion 19b is formed on the outdoor side. . An engagement receiving portion 19c is formed on the indoor side of the indoor side wall surface 19a.
A seal member 44 made of an elastic member such as an aluminum alloy or rubber fitted into the receiving portion 19b is in contact with the lower frame 11aa, and constitutes an airtight material that prevents the cool air from flowing into the indoor side. .

A small gap is formed between the indoor side wall surface 19 a of the metal lower frame 19 and the frame 22, and a lower resin angle 24 is installed on the upper part. The lower resin angle 24 is formed in a substantially flat plate shape, its base is fixed to the stepped 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 and has elasticity formed at the tip. A resin fin 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 engagement receiving portion 19c in the vicinity of the fin portion 46 in the vicinity of the fin portion 46, and further on the frame 22 side in the lower portion of the gap. An abutting piece 49 that extends and bends or curves on the distal end side to abut against 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 engagement receiving portion 19 c 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 is elastic. Since the latching piece 48 is disengaged from the engagement receiving portion 19c by deformation, it can be removed. Therefore, the lower resin angle 24 can be attached and detached when it is damaged.
Further, the lower resin angle 24 can also be attached and detached by pulling down the tip piece 16c so that the contact piece 39 is elastically deformed and the locking piece 38 is detached from the engagement receiving portion 37.

The sliding window 1 according to the first embodiment includes the above-described airtight and heat insulating structure, and the operation thereof will be described next. The sliding window 1 shown in FIGS. 1 and 2 is assumed to be installed in a building such as a middle floor or a high floor. In the closed state of the external door 8 and the internal door 7 of the sliding window 1, on the internal door 7 side, the low temperature outside air is generated by the intermediate rail portion 15 c of the upper frame 2 and the intermediate resin frame 17 and the upper arm 10 of the internal door 7. It flows in the space between and flows into the indoor side.
The outside air flows through the gap between the metal upper frame 15 on the indoor side and the upper collar 10 of the inner shoji 7 toward the indoor side hanging piece 15d side. Here, the seal member 36 provided on the indoor side hanging piece 15d can be hermetically sealed by coming into contact with the metal upper collar 10a of the inner shroud 7. This airtight line prevents outside air from flowing beyond the seal member 36 to the indoor side.

  A part of the outside air flowing between the indoor side hanging piece 15d and the upper lid 10 of the inner 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.

Moreover, since the indoor side drooping piece 15d is surrounded by the outdoor side inner resin frame 18 and the indoor side upper resin angle 16 at the tip and both surfaces a1 and a2, the surface temperature is high and dew condensation can be suppressed. Particularly, the tip and the indoor side of the indoor side hanging piece 15d exhibit a heat insulating effect because the heat insulating layer 42 and the contact piece 39 of the upper resin angle 16 cover the indoor side surface a1 of the indoor side hanging piece 15d. Thus, it is possible to suppress the transmission of cool air to the indoors and reduce the occurrence of condensation on the indoor side surface a1 of the indoor side hanging piece 15d.
However, some of the cool air wraps around the inner resin frame 18 and comes into contact with the indoor side hanging piece 15d, so that condensation may occur on the inner and outer surfaces a1 and a2 of the indoor side hanging piece 15d. Even in this case, the indoor side hanging piece 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.

Even if the indoor side hanging piece 15d is condensed due to the low temperature and a part of the dew condensation water drops and flows downward, the dew condensation water is received by the fin 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 dew condensation water retained in the heat insulating layer 42 flows downward through the fin portion 40 due to its weight, a concave portion having a protrusion by flowing from the indoor vertical portion 10ba to the taper portion 10bb in the resin upper collar 10b. It is stored at 10bc. This also prevents the condensed water from falling indoors.
Furthermore, even if the condensed water overflows the concave portion 10bc, the condensed water does not fall on the floor surface or the like, and the multilayer glass 9 passes through the reverse tapered surface 10bd from the substantially vertical surface of the concave portion 10bc of the resin upper collar 10b. Flows down to the surface. Therefore, even if a part of the dew condensate flows downward from the resin upper wall 10b through the multi-layer glass 9 on the indoor side of the inner shoji 7, it is not noticeable.

  Further, even when low-temperature outside air enters between the outdoor-side hanging piece 15b of the metal upper frame 15 and the upper arm 10 of the external shoji 8, heat insulation can be performed as in the case of the internal shroud 7. That is, the seal member 36 </ b> A abutted between the intermediate rail portion 15 c of the metal upper frame 15 provided on the indoor side of the external shoji 8 and the metal upper collar 10 a of the external shoji 8, An airtight line is formed between them. Therefore, the outside air is prevented from entering the indoor side by the seal member 36A.

Further, the intermediate resin frame 17 is covered with 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 formed by the tip piece 17a and the fin portion 40A. Can be reduced or blocked.
Moreover, in addition to the heat insulating layer 42A, the surface on the indoor side of the intermediate rail portion 15c is surrounded by the intermediate resin frame 17, so that the surface temperature can be improved and condensation due to cold air can be prevented. Even if slight condensation occurs, it is not exposed to the indoor side and cannot be visually observed from the room because it is covered with the intermediate resin frame 17. When condensation occurs on the outdoor surface of the intermediate rail portion 15c, even if the condensed water falls, the condensed water can be stored in the heat insulating layer 42A, so that the fall can be prevented.

Further, even when a portion of the dew condensation water stored in the heat insulating layer 42A falls from the fin portion 40A, the dew condensation water that flows down can be similarly stored in the recess 10bc of the upper resin bowl 10b, and further along the multilayer glass 9 Can be washed away.
The upper resin angle 16 and the intermediate resin frame 17 are expanded and contracted by heat by locking the upper resin angle 16 to the indoor side hanging piece 15d and locking the intermediate resin frame 17 to the intermediate rail 15c. Can be suppressed.

As described above, according to the sliding window 1 according to the present embodiment, an airtight line by the seal member 36 is provided between the indoor side hanging piece 15d and the upper lid 10 of the inner limb 7, and further on the indoor side of the airtight line. Since the heat insulation line by the heat insulation layer 42 is provided, the outdoor side cold air is prevented from being transmitted to the indoor side, and the heat insulation effect that the cold outside air can be blocked by the heat insulation layer 42 is high.
Further, since the top end 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 increases, Condensation does not easily occur on the inner and outer surfaces of the piece 15d, and even if condensation occurs, it can be prevented from being seen from the indoor side, so that the appearance is good.

In addition, even if the condensation generated on the indoor and outdoor surfaces of the indoor side hanging piece 15d flows down, it can be stored by the heat insulating layer 42 provided on the upper resin angle 16, and the flow of condensed water can be suppressed. Furthermore, even if condensed water flows down from the fin portion 40 of the heat insulating layer 42, it can flow through the tapered portion 10bb formed on the resin upper collar 10b of the upper collar 10 and be stored in the recess 10bc, and further along the shape of the resin upper collar 10b. Since it can flow down on the surface of the multilayer glass 9, the fall of condensed water can be prevented reliably.
In addition, 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, assembly is easy and inexpensive without the need for caulking and fixing.
Moreover, since the same structure is provided also in the upper arm 10 of the external shoji 8, the intermediate rail part 15c of the metal upper frame 15, and the intermediate resin frame 17, the same effect 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. Other embodiments and modifications of the present invention will be described below, but the same or similar parts and members as those described in the above-described embodiments will be described using the same reference numerals.

Next, the heat insulation 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. As a difference, in the sliding window 1A according to the second embodiment, a hollow hollow covered with resin instead of the heat insulation layer 42 having a substantially U-shaped cross section provided on the upper resin angle 16 according to the first embodiment. A heat insulating layer 50 having a shape is formed. Since this heat insulating layer 50 has no opening, it cannot obtain the function of storing the condensed water that falls, but since the hollow hollow portion is formed, the heat insulating performance is further improved.

In the present embodiment, the shape of the heat insulating layers 42 and 50 in the upper resin angle 16 may be any shape as long as it can exhibit a heat insulating effect, and other appropriate configurations can be adopted. For example, instead of the U-shaped cross section or the hollow hollow shape as the heat insulating layers 42 and 50, a solid cross-sectional square shape in which the hollow portion is filled with resin, other cross-sectional shapes, or the like may be used. It may have a substantially Z-shaped cross-sectional shape so as to face the resin upper collar 10b.
Further, the resin tip pieces 16c and 17a, the soft resin fin portions 40 and 40A, or the hard resin forming the heat insulating layers 42 and 50 form a 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 is not necessarily installed.

Further, in each of the above-described embodiments, the sealing members 36 and 36A that form an airtight material are provided in the receiving portion 35 of the indoor side hanging piece 15d or the intermediate rail portion 15c and are brought into contact with the upper arm 10 of the inner and outer shoji 7 and 8.
