Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blind using an electrochromic element that develops and decolors by electrochromic phenomenon. Refers to the phenomenon in which substances change color. Technique 1/Cutrochromic elements that utilize such electrochromic phenomena are numeric display elements, X-Y markers) l
) The present invention aims to provide a novel blind in which the material element is used as the slat of the blind I.

2. Description of the Related Art Liquid crystals have conventionally been used as devices that generate color by applying a voltage, and are widely used in digital watches, electronic clocks, and the like. Glasses that use liquid crystals to change the amount of light transmitted have also been proposed, but they have not been put to practical use because they are extremely expensive, require large driving voltages, and consume large amounts of power. If you try to use a liquid crystal in a blind made of a large number of slats, you will have to apply a voltage to each liquid crystal, and therefore you will have to run electrical wiring to each liquid crystal, making the wiring complicated and requiring assembly work. This causes various problems, such as difficulty in repairing the device, and repair is rarely possible and extremely expensive.

Instead of using such liquid crystals in blinds, the present invention utilizes electrochromic elements, which have low driving voltage and relatively low power consumption, in the slats of blinds, and can be used as building blinds or vehicle blinds to reduce voltage loads. The present invention aims to provide a novel blind in which the amount of light transmission can be adjusted as desired by controlling the amount of light transmitted. In particular, in a blind, a voltage must be applied to each of a large number of blind slats, but the present invention aims to provide a blind with a simple structure that allows voltage to be applied to each slat. .

The blind according to the present invention includes a first blind made of a transparent conductive film.
A blind slat is constituted by an electrochromic element plate formed by laminating an electrochromic layer and a dielectric layer between the second electrode and the second electrode, and one end of each slat is electrically connected to the first electrode. A conductive slat hook is provided at the other end of each slat, which is electrically connected to the second electrode, and the slat support shaft protruding outward from the center of each slat hook is connected to the blind. The blind body is mechanically connected to the blind lifting and tilting link devices placed on both sides of the blind body, and conductive rails are placed on both sides of the blind body that are always electrically connected to the slat hook spindles. This is characterized in that a voltage is applied between the conductive rails on both sides of the conductive rail.

The present invention will be explained below with reference to one drawing.

In the figure, 1 is a frame of the blind, 2 is a blind main body installed in the frame, and the blind main body has a fixed vertical position. It is composed of a plurality of blind slopes (3) arranged horizontally at intervals.

The blind slat 6 is made of a transparent conductor.
An electrochromic material layer and a dielectric layer are laminated between the second electrode and the second electrode. Examples of the electrochromic material layer and the dielectric layer are shown in FIGS. 2, 6, and 4.

In the embodiment shown in FIG. 2, the slat 6 includes a transparent first electrode 4f made of indium oxide (1n203);
It is composed of a solid electrochromic material layer 3C made of tungsten oxide (WO3) and a dielectric layer d made of tantalum oxide (Ta20s) stacked between 3a and 3b, and conductive slat hooks 4a are placed on both sides thereof. and 4b are provided.

One slat hook 4a is connected to the first slat hook 4a via conductive rubber 5a.
is electrically connected to the second electrode 6a, but the second electrode 3b[
It is insulated from the other side by an insulator 6aVc. The other slat hook 4b is electrically connected to the second electrode 3b via the conductive rubber 5b, but is insulated from the first electrode 6a by the insulator 6b. These slat hooks 4a and 4b are integrally formed with a support j1]7 that projects outward from the center thereof.

In the embodiment shown in FIG.
For example, first and second electrodes 6a and 3b, solid electrochromic material layer 3C, similar to those shown in FIG.
It consists of a laminate of one dielectric layer 6d formed on a glass substrate 6e. The blind slat shown in Figure 6 is
In other respects, it is similar to the one shown in Figure 6, so
Similar parts will be designated by the same reference numerals and detailed description thereof will be omitted. However, in the structure shown in FIG. 4, in order to connect the conductive rubber 5b and the second electrode 6b, the end of the glass substrate 6e is cut out, and the conductive rubber 5b is inserted into this notch.
The tip of the is embedded.

In the embodiment shown in FIG. 4, the blind slat 6
2 is an electrochromic device having glass substrates 6e and 6f similar to those shown in FIG. 6 on both sides of a plate having a structure similar to that shown in FIG.
Since it has a structure similar to that shown in Fig. 3,
Similar parts will be designated by the same reference numerals and detailed description will be omitted.

The slats 3 described above are supported by link devices for lifting and lowering the blind and tilting the blind, which are arranged inside the blind frame 1 on the left and right sides of the blind main body. An embodiment of the link device for lifting and tilting the blind is shown in FIG. As shown in FIG. 5, this link device is composed of chain-shaped left and right vertical links 8aN8b that are sequentially continuous in the vertical direction, and horizontal links 9 that connect every other axis of these vertical links. A support shaft 7 installed on the slat hook of each of the above-mentioned slat rods is fixedly supported at the center of the horizontal link 9.

An endless lifting chain 12 is stretched between a lower floating pulley 10 and an upper driving pulley 11 driven by a motor. 12
connected to. Therefore, by rotating the driving pulley 11 and driving the endless lifting chain 12, the link device expands and contracts up and down to lift and lower the slats supported by the horizontal links 9, respectively. Further, a belt 14 is attached to the upper end of the link device, and this belt is attached to a tilting pulley 15 that rotates together with the drive pulley 11 described above.
By rotating the boot 915, the left and right vertical links 8 a N 8 b are moved up and down relatively, and the horizontal link 9 is tilted accordingly. Perform the tilting operation.

On both sides of the blind body, the frame 1 is formed with a vertically extending groove 16 through which the slat hook support 7 of the slat A passes, as shown in FIG. A conductive rail 17 is arranged to electrically connect the VC. Such conductive rails 17 are provided on both sides of the slat A, and are electrically connected to the left and right slat hook support shafts 7 of the slat, respectively, and by applying a voltage between these conductive rails, the slat is activated. The slats can be colored by applying a voltage between the first and second electrodes.

In the above blind, the slats can be moved up and down and tilted by rotating the driving pulley 11 and the tilting pulley 15 in either direction using a motor. That is, due to the rotation of the tilting pulley 15, the vertical links 8a and 8b of the linkage device move up and down relatively;
This causes the horizontal link 9 to tilt, thereby tilting the slats. At the same time, the endless lifting chain 12 moves due to the rotation of the drive pulley 11, and the horizontal link 9 at the lowest position moves vertically via the connecting link 16, thereby raising and lowering the slat. . The belt 14 is sliding on the tilting pulley 15 when the raising and lowering action of the slat continues after the slat has finished its tilting action. After the slat lifting action is complete, and when adjusting the slat tilting angle, rotate the motor in the opposite direction.
Simply rotate the tilting pulley by the desired angle.

In the blind of the present invention, the slant is composed of an electrochromic element, so by applying a voltage between the first and second electrodes, the color of the slat can be changed to freely transmit light. It can be changed. However, according to the present invention, a voltage can be applied to all the slats at the same time using a simple structure in which a conductive rail is installed on the frame of the blind and the spindle of the slat hook is always brought into sliding contact with the conductive rail. - All the slats can be colored in the same way, and the coloring of the slats can be controlled regardless of the height and angle of the slants, that is, regardless of the elevation and tilting of the blind. This does not require a complicated structure in which electrical wiring is separately provided to each slat, and can be easily and inexpensively manufactured, and is convenient for assembly, maintenance, and repair.
