DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure of a heat insulating sash, and can be used for a heat insulating sash having a shoji made of metal such as aluminum.

[0002]

2. Description of the Related Art Conventionally, among the shojis constituting a heat insulating sash, there is a type in which a horizontal frame and a vertical frame each have a metal indoor member and a metal outdoor member connected by a heat insulating material. In such a shoji, the outdoor member is exposed to the outside air and has a low temperature, but the low heat is not transmitted to the indoor member because the heat transfer is prevented by the heat insulating material. That is, a heat insulating material forms a heat insulating line between the indoor member and the outdoor member, thereby suppressing a decrease in the surface temperature of the indoor member.

[0003] In a heat insulating sash provided with an indoor-side shoji and an outdoor-side shoji, one of a horizontal frame and a vertical frame forming each of the sliding doors is a combination frame overlapping in the indoor and outdoor directions.
Also in this assembling frame, in order to ensure heat insulation, a heat insulating material connecting the indoor member and the outdoor member is arranged at the same position as other frames, and an insulating line is provided at the center in the indoor and outdoor directions. It had to be provided. However, if the heat insulation line of the stairs is provided at the center in the indoor and outdoor directions, the heat insulating material is exposed to the indoor and outdoor in the indoor and outdoor sliding doors, respectively, so that the internal appearance is not good. .

[0004] Therefore, the present inventor has developed a combination frame in which the heat insulating material is not exposed, as shown in FIG. FIG.
The indoor side shoji 30 arranged on the lower side of the raising and lowering window
It is a perspective view which shows the principal part of. The indoor side shoji 30 is composed of a horizontal frame (upper frame), a combination frame 50, a vertical frame 70, and a lower frame (not shown).

[0005] The assembling frame 50 has upper surfaces 5 at right angles to each other.
1A and a main body 51 having a side surface 51B;
1, a first holding side portion 52 formed by extending a lower end of the side surface 51B downward, and a first holding side portion 52 below the upper surface 51A and
A second holding side 53 provided in parallel with the holding side 52,
A heat insulating material 113 such as urethane resin connecting the upper portions of the first and second holding sides 52 and 53;
Of the main body 51, the first and second holding sides 52,
53 is made of aluminum. The first and second holding side portions 52 and 53 and the heat insulating material 113 form a holding portion 54 having a concave cross section that is open downward. In such a combination frame 50, the main body 51 and the first holding side 52 face the indoor space, and the second holding side 53 is exposed to the outside air.

[0006] On the other hand, the vertical frame 70 has an indoor member 71 disposed on the indoor side and facing the indoor space, an outdoor member 72 disposed on the outdoor side and exposed to the outside air, and a vertical member 70 disposed substantially at the center in the indoor and outdoor direction. A heat insulating material 116 connects the indoor member 71 and the outdoor member 72, and the indoor member 71 and the outdoor member 72 are made of aluminum. The indoor member 71, the outdoor member 72, and the heat insulating material 116 form a holding section 74 having a concave cross section that opens toward the mating frame 50.

In the above-mentioned assembling frame 50 and vertical frame 70,
The hanging frame 50 is swallowed and connected to the vertical frame 70, and the indoor member 71 and the outdoor member 72 of the vertical frame 70 include:
Notches 75 to 78 for swallowing the combination frame 50 are provided. At this time, the end face 55 of the entire assembling frame 50 is abutted across the indoor member 71 and the outdoor member 72 of the vertical frame 70, and the side surface 51 </ b> B of the main body 51 and the first holding side portion 52 abut the indoor member 71. Then, the second holding side portion 53 is
2. Although not shown, the holding frame 54 is swallowed by the vertical frame 70 so that the holding portions 54 and 74 are continuous with each other. The material is to be fitted.

In such a combination frame 50, the second holding side 53 exposed to the outside air and the main body 51 and the first holding side 52 facing the indoor space are separated from each other by the heat insulating materials 113 and 114. Therefore, the low heat of the second holding side 53 is not directly transmitted to the main body 51 and the first holding side 52. In addition, both of the heat insulating materials 113 and 114 are provided in the main body 5.
1. Since they are hidden by the first holding side portion 52, they are not exposed to the indoor side (the front side in FIG. 7), and the inside appearance is also good. Although illustration and description are omitted here, the outdoor sliding door is also a combination frame having a similar structure.

[0009]

However, as shown in FIG. 7, when the mating frame 50 is swallowed and connected to the vertical frame 70, the end face 55 of the main body 51 in the mating frame 50 is connected. Since it is also in contact with the outdoor member 72 of the vertical frame 70, the low heat of the outdoor member 72 is transmitted from the contact portion to the main body 51, and the first holding side portion 52 and the indoor member 71 facing the indoor space. It is transmitted to even. Further, since the second holding side portion 53 comes into contact with the outdoor member 72, even the low heat of the second holding side portion 53 is reduced by the outdoor member 72.
And is indirectly transmitted to the main body 51 side.
For this reason, in the combination frame 50 swallowed by the vertical frame 70,
Although the inner appearance could be improved, it was difficult to maintain the heat insulating property.

An object of the present invention is to provide a frame structure of a heat insulating sash capable of improving the inner appearance of a shoji screen and maintaining the heat insulating property even when the combination frame is swallowed by another frame. To provide.

[0011]

The frame structure of the heat insulating sash of the present invention is designed so that the heat insulating material is not exposed to the inside and outside of the room by devising the arrangement of the heat insulating material in the mating frame. Insulation was ensured by interposing a heat insulator between the end surface of the main body of the assembling frame and the indoor or outdoor member of the other frame when it was swallowed and connected to another frame. Things. Specifically, one of the upper and lower horizontal frames and left and right vertical frames constituting each of the indoor and outdoor sliding doors is a mating frame, and frames other than this mating frame are arranged on the indoor side. A frame structure of a heat insulating sash including an indoor member to be formed, an outdoor member arranged on the outdoor side, and a heat insulating material connecting these members. A holding section having a concave cross section is provided, and this holding section has two holding sides provided on the indoor side and the outdoor side, and one of these holding sides is combined with the holding sides. It is connected to the frame body via a heat insulating material, the other holding side is formed continuously with the body, the end of the mating frame is swallowed by another frame, and the frame is connected to the frame. Of the indoor member and the outdoor member of the other end of the main frame and other frames connected to the mating frame, Serial and is characterized in that one of the holding side portion is interposed a heat insulating member between the side of the member to be abut.

According to the present invention, the assembling frame is composed of the main body and the holding portion provided with the holding side portions on the indoor side and the outdoor side. Since the heat insulating material is interposed between the upper part of the main body and the main body, the heat insulating material is hidden by the main body part and the holding side part on the indoor side which is formed continuously with the main body, so that the heat insulating material enters the indoor side of the heat insulating material. Exposure is prevented. In addition, since a heat insulating member is interposed between the end surface of the main body of the mat and the outdoor member of another frame connected to the main frame, the main body and the outdoor member are separated from each other, so that the member is exposed to the outside air. Is not transmitted to the member facing the indoor side. On the other hand, in the case of an outdoor sliding door, a heat insulating material is interposed between the lower portion of the holding side portion on the indoor side and the main body, so that the heat insulating material is hidden by the main body and the holding side portion on the outdoor side. Is also prevented from being exposed to the outdoor side. And, by interposing a heat insulating member between the end surface of the main body of the combination frame and the indoor member of another frame connected to the same, as in the case of the indoor side shoji,
The low heat of the member exposed to the outside air is not transmitted to the member facing the indoor side. Therefore, the inner appearance of the shoji is improved, and the heat insulation is reliably maintained.

[0013] By applying the frame structure of the heat-insulating sash of the present invention to the sliding doors of the up-and-down windows in which the combination frame is a horizontal frame, it is possible to provide up-and-down windows with good internal appearance and heat insulation. Become.

The frame structure at the connecting portion between the vertical frame 70 and the vertical frame 100 at the connecting portion between the upper frame 80 and the vertical frame 100 constituting the outdoor side shoji 40 is the same as the structure generally implemented conventionally. Here, illustration and description of those frame structures are omitted.

A description will now be given of the state of low heat transfer in the combination frames 50, 90 of the indoor side shoji 30 and the outdoor side shoji 40.

In the indoor side shoji 30, as shown in FIGS. 2, 4 and 5, the second holding side portion 53 of the combination frame 50 and the outdoor member 72 of the vertical frame 70 are exposed to the outside air and have a low temperature. However, since the heat insulating member 130 is interposed, the low heat of the outdoor member 72 is not transmitted to the main body 51 of the combination frame 50. Therefore, the low heat is not transmitted to the first holding side portion 52 or the outdoor member 71 through the main body 51. Further, the low heat of the second holding side 53 is not indirectly transmitted to the main body 51 through the outdoor member 72.

On the other hand, as shown in FIGS. 2 and 6, in the outdoor side shoji 40, the main body 91 of the assembling frame 90, the first holding side 9
2 and the outdoor member 102 of the vertical frame 100 are exposed to the outside air. However, the low heat of the main body 91 is not transmitted to the indoor member 101 by the interposition of the heat insulating member 150. For this reason, the low heat is not transmitted to the second holding side portion 93 through the indoor member 101, and the low heat of the outdoor member 102 is also indirectly transmitted through the main body 91 to the indoor member 1.
01 is not transmitted.

Since the heat insulating portion 130 is interposed between the end surface 55 of the combination frame 50 and the inner surface 109 of the vertical frame 70, the outdoor member 72
In addition, the transmission of the low heat of the second holding side portion 53 to the main body 51 of the mating frame 50 facing the indoor space, the first holding side portion 52, and the indoor member 71 of the vertical frame 70 can be reliably suppressed.

Further, since the heat insulating member 150 is interposed between the end surface 95 of the hanging frame 90 and the inner surface 109 of the vertical frame 100 in the outdoor sliding door 40, the low heat of the main body 91 and the outdoor member 102 reduces the indoor heat. Transmission to the interior member 101 of the vertical frame 100 facing the space and the second holding side 93 of the mating frame 90 can be reliably suppressed.

As described above, the heat insulation of the indoor side sash 30 and the outdoor side sash 40 can be reliably maintained, and the raising / lowering window 10 excellent in heat insulation can be provided.

At this time, since the heat insulating members 130 and 150 can be attached to the vertical frames 70 and 100 with screws 131 and 151 in advance, the connecting frames 50 and 90 and the vertical frames 70 and 100 are connected. Work does not become complicated.

Then, each of the heat insulating materials 113, 114, 11
9 and 120 are the main bodies 51 and 91 and the first holding side 5
Because it is hidden by 2,92, it is not exposed indoors and outdoors.
In addition to the inner appearance of the indoor side shoji 30 and the outdoor side shoji 40,
The design of the entire window 10 can be improved.

The present invention includes the following modifications and the like. For example, in the above-described embodiment, the heat insulating members 130 and 150 can be attached to the vertical frames 70 and 100 in advance by the screws 131 and 151. However, the heat insulating members 130 and 150 are not limited to the screws 131 and 151. You may. Further, the heat insulating members 130 and 150 are simply provided with the combination frames 50 and 90 and the vertical frames 7 without using any attaching means.
It may be only interposed between 0 and 100. However, it is desirable that the above-mentioned effect can be obtained by being attachable.

In the above embodiment, the heat insulating member 1
Although 30 and 150 are made of synthetic resin, they may be made of, for example, wood in addition to synthetic resin. Further, the shape of the heat insulating member and the like may be appropriately determined in consideration of the shapes of the assembling frame and the vertical frame. For example, notches 7
In the case where neither 7 nor 107 is provided, the shape of the heat insulating member is added to the end surfaces of the assembling frames 50 and 90,
It may be formed so as to cover the side surface on the outdoor side and the side surface on the indoor side of the main body 91. Alternatively, the heat insulating members 130 and 150 in the above embodiment have a shape that covers the entire end faces 55 and 95 of the assembling frames 50 and 90.
Since only the end surface 55 and the outdoor member 72 need not be in contact with each other, and only the end surface 95 of the main body 91 and the indoor member 101 need not be in contact, the shape of each heat insulating member is substantially the same as that of the heat insulating members 130 and 150. It may be half-shaped.

Further, the main body 51 of the assembling frames 50 and 90,
The shape of 91 is not limited to the above-described embodiment. For example, by forming the main body 51 into a shape that cuts off the side surface and the upper surface 51A on the outdoor side and does not contact the outdoor member 72, the main body 51 and the outdoor A heat insulating material made of an air layer may be interposed between the member 72. Similarly, the main body 91
An air layer may be interposed between the main body 91 and the indoor member 101 by cutting off the side surface and the bottom surface 91A on the indoor side so as not to contact the indoor member 101.

In the above embodiment, the combination frame 5
0, 90, the first holding sides 52, 92 and the second
Although the heat insulating materials 113 and 119 are disposed between the holding sides 53 and 93, these heat insulating materials are not necessarily essential to the present invention, and the first holding sides 52 and 92 and the second holding side are provided. What is necessary is just to be separated from each other so that heat transfer is not performed between 53 and 93. However, by arranging the heat insulating materials 113 and 119 as in the embodiment, the rigidity of the assembling frame can be increased, and the holding side portions 5 can be increased.
Since the extrusion molding is performed in a state where the portions 2, 53, 92 and 93 are connected, there is an effect that the extrusion molding can be performed under favorable conditions.

Further, in the above embodiment, each heat insulating material 1
Although the injection method is used for all of the samples 10 to 121, a pre-formed plate-like heat insulating material may be prepared, and the heat insulating material may be interposed between the members by caulking with the members on both sides. Further, such a caulking method and an injection method may be used in combination.

In the above-described embodiment, the raising and lowering window 1
However, the frame structure of the heat-insulating sash of the present invention may be applied to, for example, a sliding window provided with a shoji such that the summing frame is swallowed by the upper frame and the lower frame. In short, it is only necessary that the assembling frame is applied to a shoji that is swallowed and connected to another frame.

[0050]

As described above, according to the present invention, since the heat insulating material constituting the combination frame is disposed at a position hidden by the main body and one of the holding sides, the heat insulating material is prevented from being exposed. In addition to improving the inner appearance of the shoji, a heat insulating member is interposed between the mating frame and other frames to which the mating frame is swallowed and connected. This has the effect that the heat transfer can be reliably blocked by the heat insulating member, and the heat insulating property of the shoji can be improved.
