Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating shoji door having a reduced prospective size without increasing the heat transmission coefficient of the shoji.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating sash, there is a heat insulating sash in which a frame and a shoji are compositely assembled through a heat insulating material to reduce heat transfer from the outside to the inside. The structure of such a heat insulating sash will be described with reference to FIG. 3, which is a cross-sectional view of the lower rail and the lower frame of the shoji. The lower frame 1 includes a lower frame outer member 1a, a lower frame intermediate member 1b, and a lower frame inner member 1c. The lower frame outer member 1a and the lower frame intermediate member 1b, and the lower frame intermediate member 1b.
The heat insulating bridges 2 and 3 made of synthetic resin are interposed between and the lower frame member 1c. On the other hand, even in the external shoji,
The lower rail 5 is composed of a lower rail outer member 5a and a lower rail inner member 5b, and a heat insulating bridge 6 made of synthetic resin is interposed therebetween. Similarly, in the inner shoji, a heat insulating bridge 9 made of synthetic resin is interposed between the lower rail outer member 8a and the lower rail inner member 8b. This prevents heat transfer from the outer members 1a, 5a, 8a to the inner members 1c, 5b, 8b by the heat insulating bridges 2, 3, 6, 9 and, as a result, cooling of the inner members 1c, 5b, 8b. Are prevented,
The heat transmission coefficient of the heat insulation sash is extremely small.

Further, for example, in the lower rail 5 of the shoji, a flange 11 is extended outward from the lower portion of the lower rail inner member 5b, and a groove 12 is formed at the tip thereof.
The lower crosspiece outer member 5a is also formed with a groove 13 so as to face No. 2, and the above-described heat insulating bridge 6 is loaded in these groove 12, 13. On the lower surface of the flange 11,
A door roller 14 is attached, and the door roller 14 is configured to be engaged with a rail 15 formed on the lower frame outer member 1a. The flange 16 of the shoji screen and the door roller 1
The structure of 7 is the same as that of the above-mentioned external shoji.

[0004]

However, in the lower crosspiece of the shoji of the heat insulating sash, the follower 11,
Door rollers 14 and 17 are attached to the lower surface of 16, and heat insulating bridges 6 and 9 are arranged next to the door rollers 14 and 17 in the prospective direction. In other words, door wheels 14 and 17 and heat insulation bridge 6,
9 and 9 are arranged in parallel. Therefore, as shown in FIG. 3, a prospective dimension α for the door roller and a prospective dimension β for the heat insulation bridge are required, and the prospective dimension (α + β) of the lower rail of the shoji screen is required. )
Has become relatively large. As a result, there are disadvantages that the shoji becomes thicker and space is disadvantageous, and that the aluminum material used for the lower crosspiece of the shoji increases and the manufacturing cost is also disadvantageous.

Although not shown in detail in FIG.
The door rollers 14 and 17 are generally composed of a tire and two metal frames for holding the tire. Therefore, if the metal frame of the door roller may come into contact with both the outer member and the inner member of the aluminum lower rail, for example, cold heat is transmitted through the metal frame of the door roller. There is a case that the heat transmission coefficient of is worse. Therefore, when solving the above-mentioned drawbacks, it is necessary to consider the arrangement of the metal frame of the door roller, which cannot be easily solved.

SUMMARY OF THE INVENTION An object of the present invention is to provide an adiabatic sliding door door having a reduced size without increasing the heat transmission coefficient of the sliding door.

[0007]

In order to achieve this object, the present invention provides a heat insulating shoji which is four-sided by an upper rail, a lower rail and left and right vertical rails which are formed by connecting an inner member and an outer member with a heat insulating bridge. In a heat-insulating shoji door in which a door roller having a metal frame is attached to the lower rail of the door, a side portion of the door roller frame is pressed by a notch provided in the lowermost insulation bridge of the lower rail, and the upper side thereof The upper part of the frame of the door roller is brought into contact with the heat insulating bridge of, and further, the frame of the door roller is not brought into contact with the lower rail outer member and the lower rail inner member at the same time,
The feature is that a door roller is installed.

[0008]

As described above, according to the present invention, the door roller is arranged between the cutout lowest insulating bridges and below the upper insulating bridges. Therefore, the heat insulating bridge and the door roller are not arranged in parallel as in the conventional case, but so to speak, the heat insulating bridge is arranged so as to cover the door roller. Therefore, the width in the prospective direction of the lower shoji rail can be suppressed to the required dimension of the heat insulating bridge or the door roller, and this width can be made relatively small. As a result, the space for the shoji screen can be reduced, which is advantageous in terms of space, and the amount of the aluminum material used for the shoji screen can be reduced, so that the manufacturing cost can be reduced. Moreover, since the frame of the door roller is not in contact with the lower rail outer member and the lower rail inner member at the same time,
Cold heat is not transmitted through the metal frame of the door roller, and the heat transmission coefficient of the shoji is not increased.

[0021]

As described above, in the present invention, the heat insulating bridge and the door roller are not arranged in parallel as in the conventional case, but so to speak, the heat insulating bridge is arranged so as to cover the door roller. Therefore, the width in the prospective direction of the lower shoji rail can be suppressed to the required dimension of the heat insulating bridge or the door roller, and this width can be made relatively small. As a result, the space for the shoji screen can be reduced, which is advantageous in terms of space, and the amount of the aluminum material used for the shoji screen can be reduced, so that the manufacturing cost can be reduced.

Moreover, since the frame of the door roller is not in contact with the outer member of the lower rail and the member inside the lower rail at the same time, the cold heat is not transmitted through the metal frame of the door roller, and the heat flow through the shoji screen. Do not increase the rate.
