It is.

Next, mounting of the resin frames 60 to 62 will be described. As described above, the frame 10 and the door frame 2
0, and resin frames 60 to 62 are attached to the indoor side surface of the shoji frame 40. In other words, the skeleton frame 10, the door body frame 20, and the shoji frame 40 according to the present embodiment are composed of a combination of an aluminum mold material on the outdoor side and resin frames 60 to 62 on the indoor side. First, as shown in FIGS. 1, 3, and 4, the resin frame 60 attached to the indoor side surface of the frame 10
0b and a mounting portion 60a to the mounting portion 19a are formed, and are formed to be thick and three-dimensional as a whole.

Since the resin frame 60 is positioned so as to face the interior of the door body frame 20 on the indoor side in a superposed state, the resin frame 60 also serves as a decorative frame.
Shapes and colors are selected. Further, as shown in FIGS. 1, 3, and 4, a sealing material that comes into contact with the interior surface of the opposite resin frame 61, which will be described later, is provided on the exterior side surface of the resin frame 60.

Next, the mounting portions 29a, 2
As shown in FIGS. 1, 3, and 4, the resin frame 61 to be attached to the 9b is formed by a flat portion 61b on the indoor side and an attachment portion 61a, and is formed as a thin and plate-like as a whole. The resin frame 61 is provided with feet 61d for forming a heat insulating space 61c that is fixed to the door body frame 20.
The resin frame 61 may be appropriately designed according to the shape of the indoor side surface of the door body frame 20, but in the embodiment, the resin frame 61 is partially formed to be thick in the indoor and outdoor directions. Also, the resin frame 62
Resin frame 61 which is opposed to flat portion 62b of
Is provided with a soft protruding piece 61e for improving airtightness, and constitutes a sealing material. The configuration of the mounting portion 61a is basically the same as that of the mounting portion 60a of the resin frame 60 for the skeleton frame 10.
The configuration is the same as that described above. Also in this resin frame 61, while improving the heat insulation function is the biggest issue, its shape, material,
By appropriately selecting colors and the like, it is possible to make the design excellent.

Next, the mounting portions 49a, 49b of the shoji frame 40
As shown in FIGS. 1, 3 and 4, the resin frame 62 to be attached to the indoor side has a flat portion 62 b on the indoor side and an attachment portion 62 to the shoji frame 40.
a. In the resin frame 62, a separately formed pressing edge 62 c having an L-shaped cross section, which sandwiches the shoji board 31 at the periphery thereof, is disposed. The pressing edge 62 c is
An extension 62d is formed between the inner surface of the shoji board 31 and an inner side surface thereof. The end of the extending portion 62d is formed as a protruding piece 62e, abuts on the shoji board 31 via the soft tongue piece 62f, and forms a sealing material. The interior side surfaces of the extension 62d, the resin frame 62, and the resin frame 61 for the door body frame 20 are flush with each other. Therefore, the indoor surface of the door body frame 20 is flush with the resin frames 61 and 62 and the pressing edge 62c.

With the above structure, hot air and cold air transmitted and radiated from the aluminum mold located outside the room are not transmitted to the room because they are insulated by the resin frames 60 to 62 on the room side. In particular, by disposing a sealing material between the synthetic resin frames 60, 61, and 62 facing each other in the indoor and outdoor directions, the aluminum mold material constituting the door body frame 20 is spatially shut off from the indoor side. The heat insulation effect can be further improved. In addition, since the indoor side is unified with the resin frames 60 to 62, selection of the material, shape, and color of the resin frames 60 to 62 is facilitated, and there is more room for design choice.

Further, the resin frame 6 is attached to each of the frames 10, 20, 40.
In mounting 0 to 62, the mounting portions 60a, 61a,
The mounting is assured by positioning 62a outside the protruding portion 60b and the flat portions 61b and 62b and using a combination of the caulking means and the press-fitting engagement means. Also, even if a slight length or other distortion occurs between the frames due to a difference in the coefficient of thermal expansion due to a difference in material between the frames 10, 20, 40 and the resin frames 60 to 62, the crimping engagement means was used. Since the distortion can be absorbed by a slight displacement or elastic deformation of the portion, the occurrence of distortion such as warpage or bending of the frame or frame is small.

In addition, the frame,
The frame can be designed precisely, and confidentiality and heat insulation can be improved. As a result, the frames 10, 20, 40 of the aluminum
And the total size (width dimension) of the resin frame 60 and the resin frame 60 to 62 can be reduced, and a shape that looks good in appearance can be obtained. Furthermore, by making the indoor side surfaces of the resin frames 60 to 62 flush with each other, and displacing the sash storage portion 21 to the outside of the door body frame 20, the structure full of a sense of weight is seen from the outside. In addition, the interior side has no protrusion, so the interior space can be widened, and it is easy to be flush with the walls and windows around the heat-insulating door, so it has an excellent design. It can be.

Further, since the extending portion 62d is formed, the aluminum frame is not seen from the indoor side and the resin frame 6 is not formed.
Since only 0 is visible, the design effect is also excellent. In the above embodiment, the engaging portions 19b, 29b, 49b
Adopted the engagement means by pressing, but in addition,
Other means such as latching may be adopted, and any configuration may be used as long as the engagement portion between the aluminum frame and the resin frames 60 to 62 can slightly move (shift) each other. In the above claims, the reference numerals corresponding to the embodiments are attached.
The present invention is not limited to this.

[0021]

According to the present invention, the following effects can be obtained by the above configuration. 1. According to the first or second aspect of the present invention, heat transfer and radiant heat from the aluminum mold member are blocked by the resin frames, and hot or cold air outside the room is not transmitted to the room, thereby improving the indoor comfort. In addition, since the interior of the room is unified with the resin frame, the color and shape of the resin frame can be freely selected, so that there is more room for design choice. In addition, a visual effect can be expected since the aluminum mold is not visible from the indoor side and only the resin frame is visible. In particular, the inner edge of the synthetic resin frame mounted on the indoor side surface of the skeleton frame and the outer edge of the synthetic resin frame mounted on the indoor side surface of the door body frame are overlapped to form an opposing surface, and the indoor side surface of the door body frame is formed. The above-mentioned effect can be further ensured by forming the opposing surface by setting the inner edge of the synthetic resin frame mounted on the outer edge of the synthetic resin frame disposed on the indoor side surface of the shoji frame to the overlapping position. .

2. According to the third aspect of the present invention, in addition to the effect of the first aspect of the present invention, since the aluminum member constituting the door body frame is not spatially connected to the indoor side, heat transfer accompanying air convection is achieved. And the heat insulation effect can be further improved.
