Description

[Detailed description of the invention] This invention relates to a window blind that keeps the interior cool in the summer and warm in the winter.

Blinds are generally attached to windows to prevent unnecessary peeks into the room from outside, and blinds are also a type of blind. This invention is not intended for conventional stirrup-shaped blinds, but for roll-type blinds, which is why this invention is called a blind.

By the way, the primary purpose of this type of blindfold is to prevent people from looking into the room from outside, but in order to achieve this purpose, the entire window must be closed. It has to be shut off. Then, in the summer, the room becomes very hot, and in the winter, because it does not receive much sunlight, it becomes rather cold. In order to solve this problem, it would be best to open this blindfold,
This will not be a blindfold in any way.

Therefore, this idea installed rollers at the top and bottom, passed an endless band around these rollers, and divided the outer surface of this band into halves according to high and low brightness colors. The outside surface is painted with a bright color, and the back side is painted with a low brightness color, and the outside surface is painted with a low brightness color, and the back side is painted with a high brightness color. The side with a lighter color is facing outside, and in the winter, the side with a lighter color is facing outside, and each reflects and absorbs solar heat. First, it was developed with the aim of providing a window blind that maintains a comfortable indoor temperature.

Now, one embodiment of the window blind according to this invention will be described based on the drawings. Reference numeral 1 denotes a frame configured to engage with the sill and lintel of the window, and the upper and lower parts of the frame 1 are , rollers 2 and 3 are rotatably disposed, respectively. 4
is an endless band passed over these rollers 2 and 3, and this band 4 is colored as follows. That is, in the case shown in the figure, the left side A and the right side B are located at the positions shown with the upper part of the band 4 in contact with the upper part of the roller 2 and the part in contact with the lower part of the lower roller 3 as boundaries, respectively. A temporary distinction is made between And this left side A
The outer surface, that is, the left surface in the illustrated state, is painted with a low brightness color, and the back surface is painted with a high brightness color. On the other hand, on the right side B, the outer surface, that is, the right surface in the illustrated state, is painted with a high brightness color, and the back side is painted with a low brightness color. When coloring is done in this way, the result is that in each figure, starting from the outer surface on the left,
It becomes high, low, high.

As mentioned above, this is used by engaging with the window rail (sill, lintel), but if it was used in the summer, the surface that appears outside the window could be The band 4 may be positioned so that the color is high. In this way, solar heat is reflected in brighter colors and is prevented from entering the interior, and even if it does enter, the amount is considerably small, and the heat that does enter is also reflected in brighter colors. It turns out. In addition, in the winter, if the band 4 is positioned so that a low-brightness color appears outside the window, solar heat will be absorbed by this color, and the band 4 will
The light enters between the light and the band 4, and is further absorbed by the less bright colors and enters the room. In order to move the band 4, the rollers 2 and 3 may be rotated by any desired means.

Note that this blindfold is normally used in a position where it is in contact with the outside air, but in this case, it is expected that the band 4 will be swayed by the wind. In order to prevent this, several cylindrical stabilizing members 5 as shown in the figure may be interposed between the band members 4. Incidentally, the stabilizing member 5 may be arranged so as to be sandwiched from both sides of the band 4 instead of being interposed between the band 4 as described above (see FIG. 3). In addition, in order to adjust the tension of the band 4, long holes 6 are bored in both sides of the frame 1 where the upper and lower rollers 2 and 3 are disposed relative to the frame 1. 2 and 3 may be slightly moved up and down.

As mentioned above, according to the window blind according to this invention, the coloring of the band is differentiated by high and low brightness, so it can be used for summer and winter, and as a result of this selective use, it can be used indoors in summer. This has the effect of making it as difficult as possible for solar heat to enter during the winter, and conversely making it easier for the sun's heat to enter during the winter.
