Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating door having a lifting / lowering shoji which is constructed by housing a shoji in a vertically movable manner inside a composite frame body in which an exposed indoor side portion of a metal frame is covered with a resin frame. .

[0002]

2. Description of the Related Art Conventionally, there has been provided a door having a raising / lowering shoji which is constructed by housing a pair of shoji on the outdoor side and an indoor side so that it can be moved up and down. Widely used as etc. As the frame body of such a door, the one mainly made of a metal frame made of aluminum or the like has been mainly used, but in recent years, the indoor side portion of the metal frame is covered with a resin frame made of a resin having a low thermal conductivity. Composite frames have been proposed. By covering the metal frame with a resin frame, the heat insulation is improved to prevent dew condensation on the indoor side. Furthermore, the visual coldness peculiar to the metal frame is eliminated and the interior decoration is integrated. By doing so, the design is improved.

An example of a conventional heat insulating door using such a composite structure will be shown. FIG. 7 is a vertical sectional view of a conventional heat insulating door, and FIG. 8 is a horizontal sectional view of the heat insulating door of FIG. These Figures 7 and 8
In the conventional heat-insulating door 100, two shoji screens 103 and 104 are housed in a frame body formed of a metal frame 101 and a resin frame 102 that covers an exposed portion on the indoor side. Then, as shown in FIG.
Shoji frame (outdoor guide frame) 105 for guiding the user and shoji frame (indoor guide frame) for guiding the indoor shoji 104
106 and 106 are both configured by the metal frame 101,
Of these, the indoor guide frame 106 has its exposed surface on the indoor side covered with resin members 107 and 108 that are a part of the resin frame 102.

In the conventional shoji of the heat insulating door, shoji 103 and 104 are pieces 10 on the indoor side of the outdoor guide frame 105.
5a and the piece 106a on the outdoor side of the indoor guide frame 106 are separated from each other by the intermediate wall 110 formed. The intermediate wall 110 was covered with a resin wall 109 formed by extending the resin member 108 toward the center side in the mounting direction so that the vertical metal frame of the shoji screen 103 would not be exposed indoors.

Conventionally, the heat insulating door 100 is provided with a watertight structure for maintaining watertightness between the frame and the shoji 103, 104 or between the shoji 103, 104. Specifically, as shown in FIGS. 7 and 8, each frame member is provided with a sealing material 111 made of resin or mohair material, and when the shoji screens 103 and 104 are closed, these shoji screens 1
The watertight structure between the frame and the shoji 103, 104 was formed by bringing the sealing material 111 into contact with the side surfaces of 03, 104. In addition, a sealing material 112 is separately provided on the upper frame (summing frame) of the shoji screen 104 on the indoor side.
The watertight structure between the shoji screens 103 and 104 was formed by bringing the sealing material 112 into contact with the side surface on the indoor side of the shoji screen 103 in a state where the shoji screens 3 and 104 were closed.

[0006]

However, in such a conventional heat insulating door, not only the outdoor guide frame 105 but also the indoor guide frame 106 is formed of a metal frame, and the surface thereof is covered with the resin members 107 and 108. Therefore, the guide structure of the shoji 104 on the indoor side has a double structure of metal and resin, which is one of the factors that increase the cost. Further, it takes time and effort to mount the plurality of resin members 107 and 108, resulting in poor assembly efficiency.

Further, in the conventional heat insulating door, the intermediate wall 1
Since the resin wall 109 is provided in 10, when the shoji 103 on the outdoor side is impacted by the wind blown from the outdoor side, the impact may be transmitted to the intermediate wall 110 to cause damage. There was a problem from the above point of view. In addition, a support structure composed of rectangular portions 113 to 116 is arranged on the four sides of the frame body, and this support structure ensures the support strength of the frame body. However, as shown in FIGS.
13 to 116 and the intermediate wall 110 were arranged at completely different positions with respect to the expected direction, so that the rectangular portions 113 to 11
6 has a step between the intermediate wall 110 and the intermediate wall 110 to concentrate the stress, which is a problem in securing the integral strength. Further, since such a step is formed, the work efficiency in manufacturing and assembling the frame is hindered.

Regarding the watertight structure, the sealing material 11
Since the sliding doors 1 and 112 are in contact with the side surfaces of the shoji screens 103 and 104, a frictional force is generated between the sealing materials 111 and 112 and the shoji screens 103 and 104 every time the shoji screens 103 and 104 are moved up and down, and There is a problem that the operability of 103 and 104 is deteriorated. Further, since the seal materials 111 and 112 are always rubbed, there is a problem that the wear is severe.

In particular, with respect to the watertight structure between the shoji screens 103 and 104, since the sealing material 112 is provided separately in the summing frame of the shoji screen 104, water will flow from between the sealing material 112 and the summing frame. I was worried about the watertightness such as the possibility of infiltration. In addition, when attached separately, a step is apt to occur between the summing frame and the sealing member 112 because they are connected to each other, so that the summing frames of the inner and outer shoji screens 103 and 104 appear to be discontinuous with each other. There is also a problem in that the appearance may be impaired and dust and the like are likely to accumulate on the steps.

The present invention has been made in view of such problems in the conventional heat insulating door having a lifting / lowering shoji, and has a simple and strong frame structure and a watertight structure which does not hinder the operation of the shoji. An object of the present invention is to provide an insulated door having a lifting and lowering screen.

[0011]

In order to solve the problems in the conventional heat insulating door having the lifting and lowering doors, the present invention according to claim 1 covers the exposed portion on the indoor side of the metal frame with a resin frame. In the inside of the composite frame body, in an insulated door having a raising and lowering shoji that is configured to vertically house an outdoor shoji and an indoor shoji, an outdoor guide frame for guiding the outdoor shoji, An indoor guide frame for integrally guiding the shoji on the indoor side, which is integrally formed only by the metal frame, is integrally formed only by the resin frame, and the indoor side of the outdoor guide frame and the indoor An indoor side is formed by supporting the indoor guide frame with the outdoor guide frame while forming the intermediate side wall by forming the outer sides of the guide frame having almost the same finding width and abutting each other.

That is, when the shoji screen 5 is lowered, its movement is restricted by the watertight block 72 at its lower end position, and the shob 5 is stably placed on the watertight block 72. In this way, the watertight block 72 functions as a weight receiver.
As a result, it functions as a stopper for stopping the shoji 5 at a predetermined lower end position, so that it is not necessary to separately provide a dead weight receiver or a stopper.

As described above, the watertight piece 70 is brought into contact with the upper surface of the shoji 4 instead of the side surface, and the watertight piece 71 and the watertight block 72 are brought into contact with the lower surface of the shoji 5 instead of the side surface. When moving the shoji 4, 5 up and down, the shoji 4, 5 and the watertight pieces 70, 71 and the watertight block 7
Since friction does not occur between the sliding doors 2, the sliding doors 4 and 5 can be smoothly operated by preventing resistance from being raised and lowered. Further, it is possible to prevent the watertight pieces 70, 71 and the watertight block 72 from being worn early.

Further, the watertight structure between the shoji screens 4 and 5 will be described. As shown in FIG. 6, the resin upper frame 41 of the upper frame (summing frame) of the shoji 5 on the indoor side is formed so as to cover the upper surface of the metal upper frame 31 and reach the outdoor side. A watertight piece 73 is integrally formed on the resin upper frame 41 by further extending its tip end to the outdoor side. This watertight piece 73 is used for the outdoor and indoor shoji screens 4,
In the state where 5 is closed, it abuts on the indoor side surface of the resin lower frame 42 of the outdoor shoji 4. Watertight piece 7
Since 3 is formed integrally with the resin upper frame 41, there is no possibility that water will enter between the watertight piece 73 and the resin upper frame 41, and the watertightness is improved as compared with a separate body.

The watertight piece 73 is formed such that its upper surface is flush with the upper surface of the resin upper frame 41. Therefore, the summing frames of the shoji screens 4 and 5 can be seen as a united body to improve the appearance, and the upper resin frame 41 and the watertight piece 7 can be improved.
Since there is no step between the three, it is possible to prevent accumulation of dust and the like.

A locking claw 73 for connecting the resin upper frame 41 to the metal upper frame 31 is provided at a position adjacent to the lower side of the watertight piece 73.
Since a is integrally provided on the upper resin frame, even if the watertight piece 73 contacts the lower resin frame 42 and receives a load in the upward direction, the load can be firmly received via the locking claw 73a. Therefore, it is possible to prevent the watertight piece 73 from floating. Also, on the indoor side surface of the resin upper frame 41,
Since the handle 74 for vertically moving the shoji 5 is integrally provided, the shovel 5 can be vertically moved at a position close to the watertight piece 73. Therefore, even if the watertight piece 73 contacts the resin upper frame 41, the shoji 5 can be stably operated without generating an extra moment with this as a fulcrum.

Although one embodiment of the present invention has been described so far, the present invention is not limited to the above-mentioned embodiment and may be carried out in various different forms within the scope of the technical idea thereof.
