Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a window material that is used for openings in buildings and transmits or blocks light depending on the amount of sunlight received.

Conventional technology In houses, buildings, and other buildings, sunlight transmitted through window glass plays an important role not only in lighting but also in shaping room temperature, and excessive sunlight causes excessive rise in room temperature even in winter. Appropriate light shielding is necessary to maintain a comfortable room temperature. For this reason, in the past, light shielding members such as eaves, blinds, and blinds have been used. Furthermore, in recent years, systems have been provided that automatically control blinds according to the amount of sunlight using a motor drive.

Problems to be Solved by the Invention However, the former types of eaves, blinds, blinds, etc. are fixed or opened and closed manually, and if they are fixed, the amount of solar radiation cannot be adjusted; It is cumbersome to open and close. Also, in the latter case,
The structure is complicated and the cost is high.

Therefore, an object of the present invention is to provide a window material that can automatically transmit or block light depending on the amount of solar radiation received, and that has a simple structure and can reduce costs. It is something to do.

Means for solving the problems and the technical means of the present invention for solving the above problems include a transparent member, a chamber formed inside the transparent member with a peripheral portion left, and a lower side of the cavity. a fluid reservoir communicating with the
The fluid is sealed in this fluid reservoir and permeates into the chamber due to volume expansion.

Effect of the present invention With the above-described configuration, when the amount of received solar radiation increases, the fluid penetrates into the chamber space from the fluid reservoir due to thermal expansion due to sunlight absorption by the transparent member, and the light can be blocked, and when the amount of received solar radiation decreases, the fluid The volume of the fluid decreases and returns to the fluid reservoir, allowing sunlight to pass through.

EXAMPLES Hereinafter, examples of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the window material 1 of the present invention is a transparent member;
The periphery of the back transparent glass plate 2.3 is integrated, and leaving this periphery, a pre-depressurized cavity 4 and a fluid reservoir 5 communicating with the lower side of the cavity 4 are formed inside. ing. A fluid 6 is sealed in this fluid reservoir 9 section 5 .

For example, the window material 1 configured in this manner has its peripheral portion connected to the wall body 7.
Attach it to the opening 8 so as to close it.

As the temperature of the glass plates 2 and 30 rises due to solar radiation absorption, the volume of the sealed fluid 6 expands, and when this exceeds the volume of the fluid reservoir V section 6, it enters the cavity 4. , to block light. At this time, the volume of the cavity 4 is reduced to the fluid reservoir 5
By setting it sufficiently smaller than , the fluid 6 can be rapidly expanded into the cavity 4 . Furthermore, when the solar radiation weakens, the volume of the fluid 6 decreases and returns to the fluid reservoir 5, allowing full sunlight to pass through.

FIG. 2 shows another embodiment of the invention.

In this embodiment, the entire fluid reservoir 6 side is curved,
This window material 1 is attached to the wall γ so as to close the opening 8, and at this time, the fluid reservoir S is placed on the e side of the room away from the light receiving part, and the movement of the fluid 6 is controlled according to the room temperature. This is what I did.

In addition to the embodiments described above, the present invention can also strengthen the response to solar radiation by arranging the fluid reservoir 5 side on the solar radiation side and actively exposing it to sunlight, and further preserving the color of the periphery of the fluid reservoir 5. Out.

In addition, by mixing a dye or the like into the fluid 6, the light transmittance can be adjusted depending on its concentration.If the dye is completely mixed in this way, it will enter the void 4 and cause discoloration.
As an indoor interior, it dynamically changes the interior landscape,
Aesthetics can be improved. Further, a reflective liquid such as mercury can be used as the fluid 6, and the reflectance can also be adjusted by mixing reflective fine powder into the fluid 6.

Effects of the Invention As is clear from the above description, according to the present invention, a fluid reservoir is formed which communicates with the cavity and the lower side of the cavity while leaving a peripheral portion inside the permeable member, and the expansion of volume is caused in the fluid reservoir. Since a fluid that can penetrate into the void is sealed in, the transmission characteristics of openings in buildings etc. can be automatically controlled according to the amount of solar radiation, for example to prevent excessive temperature rise in rooms on the south side during the day. be able to. Moreover, since the structure is simple, it can be provided at low cost.
