A heat insulating mat is constructed with the upper surface as a reflective surface, and this is placed on the indoor side of the glass window to insulate it with the air layer in the air chamber, and the reflective surface of the second connecting sheet reflects sunlight. It is characterized by being able to let in enough sunlight to the back of the room, and also being able to prevent sunlight from entering the room in the summer.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, numeral 1 is a sweeping window consisting of two sliding doors with a half-width width.
On the indoor side of the room, a heat insulating mat 2 consisting of two mats 3 and 4 with a half-width width is removably arranged.

As shown in FIGS. 2 to 6, the mat 3 includes an inner sheet material 5 and an inner sheet material 5 which face each other at an interval of, for example, about 20 mm in the indoor and outdoor directions, and whose edges 7 are welded together at the center in the opposing direction. An outer sheet material 6 is provided, and these sheet materials 5 and 6 are separated from each other through two folded portions 8 extending in the vertical direction as shown in FIGS. 2 and 6. Three air chambers 9 are formed in the width direction.

That is, both the sheet materials 5 and 6 are formed of, for example, a slightly thick transparent synthetic resin sheet having flexibility, and consideration is given to allowing sufficient outside light to be taken into the room through the sheet materials 5 and 6. has been done. Each folded portion 8 is formed into a rectangular tube shape by a pair of transparent connecting members 10 facing each other in the width direction at an appropriate interval of, for example, 50 mm, as shown in FIGS. 2 and 6. Inner sheet material 5 corresponding to 8
A communication hole 11 is provided in the center in the vertical direction.

Furthermore, inside each of the air chambers 9, there are
As shown in the figure, the first connecting sheet 12 and the second connecting sheet 13 are arranged in a zigzag shape in the vertical direction as a whole. The first connecting sheet 12 is connected to the fifth connecting sheet 12.
As shown in the figure, for example, transparent thin synthetic resin sheets or the like are arranged in a downward slope from the inner sheet material 5 to the outer sheet material 6, and the upper and lower ends are welded to the inner surfaces of each of the sheet materials 5 and 6. is formed,
Further, the second connecting sheet 13 is made of, for example, a transparent thin synthetic resin sheet, etc., which is arranged in a downward slope from the outer sheet material 6 to the inner sheet material 5, and the upper and lower ends thereof are attached to the inner surfaces of each of the sheet materials 5 and 6. It is formed by welding. Also, the one located in the lower half of the air chamber 9 of the second connecting sheet 13 has a dimension L (usually 900 or
The surface serves as a reflective surface 14 over a range of about 1000 mm). This reflective surface 14 is constructed by, for example, pasting aluminum foil or the like on the lower surface of the second connecting sheet 13 or applying a high reflectance material to the lower surface of the second connecting sheet 13.
3, the light is hardly or completely transmitted in the thickness direction from both the upper and lower surfaces.

Further, at both ends of both the connecting sheets 12 and 13, there are cut portions 1 having an arc shape as shown in FIG.
5 is provided, and a triangular unit air chamber 9a (see FIG. 5) consisting of one connecting sheet 12, 13 and one of the inner and outer sheet materials 5, 6 is connected through the cut portion 15. The interior of the air chamber 9 has a single sealed chamber structure with communication in the vertical direction. As shown in FIGS. 2 and 5, the air chambers 9 are constructed so that the air sealed inside can be completely discharged to the outside by opening a stopper 16 provided at one side of the lower end of each air chamber 9. It's summery.

Further, as shown in FIG. 7, both of the connecting sheets 12 and 13 have an inclination angle θ from the horizontal plane of 35 to 45 degrees.

The upper edge 7 of the mat 3 configured in this way
As shown in FIGS. 2 to 4, there are locking pieces 17 formed of velvet fasteners or the like at both ends in the width direction on both sides and in the vicinity of the folded part 8.
a, 17b, 17c, 17d and 18a, 18
b, 18c, and 18d are fixed respectively,
As shown in FIG.
In other words, it can be detachably attached between the sliding door and the curtain, and can be folded from the folding part 8. At this time, the edge 7 at the lower end of the mat 3 is bent along the floor 19 and comes into close contact with the floor 19, as shown in FIG. 5, and the edges 7 at both widthwise ends of the mat 3 are As shown in FIG. 6, one side is in close contact with the inner surface of the window frame, and the other side is overlapped with the edge 7 of the mat 4, which will be described later, at the position of the matching stile of the sliding door.

The other mat 4 that is paired with the mat 3
As shown in FIG. 1, unlike the mat 3, the folded part 8 is not provided, and the whole is a single air chamber 9, inside which the first connecting sheet 12 is provided.
and second connecting sheets 13 are arranged in a zigzag pattern. In other respects, it has the same structure as the mat 3 described above.

Next, the effect will be explained.

When used in the winter, both mats 3 and 4 are installed on the exhaust window 1 with the inner sheet material 5 facing indoors as shown in FIGS. 1, 5 and 6. As a result, the upper end and the outer edge 7 of each mat 3, 4 in the width direction are in close contact with the inner surface of the window frame, and the lower edge 7
are bent and come into close contact with the floor surface 19, and furthermore, the edges 7 at the inner ends in the width direction overlap each other, so that the exhaust window 1 side and the indoor side are almost completely isolated by the heat insulating mat 2.
An air chamber 9 is provided in both mats 3 and 4,
Since the air layer in the air chamber 9 functions as a heat insulating layer, a large heat insulating effect can be obtained.

In addition, since the mat 3 can be bent at the folded part 8, there is no need to remove the mat 3 when exchanging indoor air or going out to the balcony. The optimum open area can be obtained in three stages: when only 9 sections are opened, when the left end and center air chamber 9 sections are opened, and when the entire air chamber is opened.
In addition, in the case of partial opening, the locking pieces 18c and 18d located on the right side of each folded part 8 in FIG. 2 are fixed to the window frame, so that the folded parts 8 can be easily bent. Secure fixation. Moreover, since the folded part 8 is cylindrical and has an air layer inside, it is possible to suppress as much as possible a decrease in the heat insulation effect due to the provision of the folded part 8. Furthermore, since the communication hole 11 provided in the folded part 8 is located on the indoor side, even if the mat 3 should touch a window glass etc., condensed water will enter the folded part 8 through the communication hole 11. There's nothing to do.

Furthermore, since both the mats 3 and 4 are constructed as separate bodies and are only connected by overlapping the inner edges 7 in the width direction, the mats 3 and 4 can be removed by inserting your hand between the edges 7. Crescent or other auxiliary locks can be operated without removal.

In addition, the mats 3 and 4 are prevented from expanding indoors and outdoors by a large number of connecting sheets 12 and 13 arranged in each air chamber 9, and the portions of the mats 3 and 4 that protrude indoors from the window frame are Since it is only about half the thickness, the curtain can be opened and closed with both mats 3 and 4 attached, and when used in combination with a curtain, the heat insulation effect can be further improved.

In addition, arc-shaped cut portions 15 are provided at both ends of both connecting sheets 12 and 13, and the cut portions 15 communicate the interior of the air chamber 9 in the vertical direction. This is simple, and furthermore, it is possible to prevent the communication portion from bulging in the indoor/outdoor direction.

In addition, since both mats 3 and 4 are entirely made of transparent material except for the second connecting sheet 13 in the lower half having a reflective surface 14, there is no discomfort even when the heat insulating mat 2 is worn during the day. Moreover, the reflective surface 14 allows sunlight to be guided deep into the room, illuminating the entire room.

That is, the winter sun's rays shown by arrow A in FIG. 7 enter the room at an angle of approximately 50 degrees from the horizontal position on average. On the other hand, since the inclination angle θ of the reflective surface 14 is set to 35 to 40 degrees, sunlight A in winter enters the reflective surface 14 at an incident angle of 10 to 15 degrees and is reflected at the same reflection angle. become. As a result, as shown in Figure 7, light that would normally only reach point a can be guided to point b at the back of the room.
Furthermore, since the sunlight A can be directly introduced into the room through the upper and lower reflective surfaces 14, the entire room can be evenly illuminated with soft light. At this time, it is more effective if the reflective surface 14 is a diffused reflective surface.

On the other hand, when using in the summer, the locking pieces 17a, 17b, 17c of each mat 3, 4,
17d is used to install the heat insulating mat 2 on the indoor side of the sweeping window 1. As a result, the air layer in the air chamber 9 of each mat 3, 4 insulates the room, improving cooling efficiency, and as shown in FIG. Efficiency can be further improved.

That is, in the summer, sunlight B enters at an angle of about 70 degrees from the horizontal position on average. On the other hand, the inclination angle θ of the reflective surface 14 is set to 35 to 40 degrees, and by directing the inner sheet material 5 toward the outdoor side, the reflective surface 14 slopes downward toward the outdoors, so that the sunlight B in summer is The light enters the reflective surface 14 at an incident angle of 70 to 75 degrees and is reflected outside at the same reflection angle. Moreover, since the sunlight B does not enter the room through the upper and lower reflective surfaces 14, all the sunlight B within the range of the dimension L shown in FIG. 2 can be reflected outside.

In addition, the upper half of each mat 3, 4 has a reflective surface 14.
However, as mentioned above, sunlight B in summer enters at an angle of approximately 70 degrees from the horizontal position,
Therefore, due to the eaves and the like, most of the air will enter the room through the lower half of the window 1. Therefore, if the reflective surface 14 is provided in the lower half of each mat 3, 4, it is possible to almost completely prevent the sunlight B from entering the room, and moreover, the reflective surface 14 is limited to the lower half. This has the great practical effect of not obstructing the view and preventing the room from becoming too dark.

Therefore, the reflective surface 14 is provided in the lower half of each mat 3, 4, and each mat 3, 4 is installed so that the reflective surface 14 slopes downward toward the room in the winter, and the reflective surface 14 is installed in the lower half of the mat in the summer. By installing the mats 3 and 4 so that the ceiling slopes downward toward the outdoors, heating and cooling efficiency can be greatly improved.In addition, in winter, sufficient outside light is brought into the room to improve the overall indoor average temperature. Not only can it illuminate the room, but it can also block outside light in the summer to provide a moderate amount of illuminance indoors. In addition, since the upper half of each mat 3, 4 is transparent, the view is not obstructed, and there is no trouble at all even if the heat insulating mat 2 is set all the time.

In addition, since each mat 3, 4 is made of a flexible material such as synthetic resin, it can be folded into a small size by letting the air out of the air chamber 9, and can be folded into a small size by simply filling the air chamber 9 with air. It can be easily returned to its shape.

In the above embodiment, the heat insulating mats 2 are
The explanation has been given of a case where the insulating mat 2 is made up of one mat, and the folded part 8 is provided on both mats 3, 4. 4, or the heat insulating mat 2 may be folded or rolled up in the vertical direction.

Further, the locking pieces 17 and 18 for attaching the heat insulating mat 2 to the indoor side of the glass window are not limited to velvet fasteners, but may be other materials such as double-sided adhesive tape.

Furthermore, it is preferable to make the folded part 8 cylindrical, or to provide an edge 7 so that it fits tightly against a window frame, etc., from the viewpoint of further improving the heat insulation effect; Even if 8 is a single sheet or there is no edge 7, the desired effect can be obtained.

Although not specifically described in the above embodiment, the heat insulating mat 2 may be provided with an opening that can be opened and closed, and the indoor air may be exchanged through this opening.

[Effect of idea]

As explained above, in the present invention, connecting sheets are arranged in a zigzag pattern in the air chamber formed between the two inner and outer sheet materials, and the upper surface of the second connecting sheet located in the lower half is used as a reflective surface. , heating and cooling efficiency can be greatly improved. In addition, in the winter, the pine is installed so that the reflective surface faces indoors and slopes downward, and in the summer, the reflective surface faces outdoors and slopes downward. It is possible to bring enough light into the interior of the room to evenly illuminate the entire room, and in the summer, it is possible to block outside light and provide an appropriate level of illuminance inside the room. In this case, since the reflective surface is limited to the lower half of the pine tree, the light reflected from the reflective surface may directly enter the eyes of people in the room, or the room may become too dark due to blinds. do not have. Also, since the upper half of the mat is transparent, the view is not obstructed, and there is no problem in keeping it in place all the time.

In addition, since the mat is made of flexible material, it can be folded into a small size and stored by letting the air out of the air chamber, and it can be returned to its normal shape simply by reinjecting air into the air chamber. . Therefore, there is no need to particularly form the reflective surface with a hard material, and a great practical effect can be obtained.
