Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a dimmable multilayer panel, and more specifically, it can be suitably applied to places where maintenance and inspection work is particularly difficult, such as skylights located at high places. Regarding a dimmable multilayer panel.

[Conventional technology]

Buildings have daylight surfaces formed by windows of various structures. In this case, blinds or curtains are usually attached to the windows that are used as lighting surfaces to make it possible to adjust the amount of light that passes through, and to protect privacy by preventing people from peeking into the room from the outside. It is being taught. On the other hand, light control glass that uses liquid crystal elements and electrochromic elements that can electro-optically block light rays has also been proposed, and by applying this light control glass to window glass, blinds and It is becoming possible to achieve the same effect as curtains. [Problems to be Solved by the Invention] By the way, many buildings have daylighting surfaces such as skylights installed at high places. When using conventional light control means such as blinds and curtains for lighting surfaces installed at such high places, necessary maintenance work such as cleaning dirt and repairing malfunctions becomes difficult. Another disadvantage is that the dimming conditions that can be selected are fixed, making it impossible to respond flexibly to various demands regarding daylighting that vary from time to time. In addition, when using a light control means made of the above-mentioned light control glass, there are disadvantages in its durability, and there are problems in that it requires a lot of money and time to replace it. This has the disadvantage that it cannot respond to the individual and diverse demands of users, such as the desire to allow visible light to enter. [Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems encountered in conventional light control means, and its structural feature is that two light control means are spaced apart from each other with a spacer interposed therebetween. It is made of two transparent plates and is rotatably arranged in the space formed between these transparent plates.The cross section is an equilateral triangle, and each side has three sides formed with different light transmission performance. The hollow cylinders are composed of a plurality of hollow cylinders, and when each of these hollow cylinders is rotated so that its - side is parallel to the transparent plate, the hollow cylinders cause the hollow cylinders to rotate parallel to the transparent plate. The reason is that it is possible to form and arrange a continuous surface. Further, each of the hollow cylinders in the present invention is formed with three surfaces, a shielding surface, a heat ray reflecting surface, and a transmitting surface, so that the light transmitting performance of each surface can be made different. Furthermore, the hollow cylindrical body has a gear fixedly attached to one end of each hollow body meshing with a driving member having a tooth groove provided along the length direction of the hollow cylindrical body. It is desirable to be able to rotate it. [Function] For this reason, each of the hollow cylinders can be rotated to a desired rotation angle, and a surface having the desired light transmission performance can be positioned on the light incident side. Dimming conditions can be set. Moreover, if two transparent plates are separated via a spacer and their peripheral parts are sealed with a sealant, the movable part including the hollow cylinder is sealed by the two transparent plates via the spacer. Since it can be confined within the formed space, it is possible to reduce the causes of contamination and malfunctions, and the need for maintenance and inspection work can be reduced accordingly. [Example] Hereinafter, an example of the present invention will be described based on the drawings. The present invention consists of two transparent plates 12. 13, and these transparent plate materials 12. 13 A plurality of hollow cylinders each having an equilateral triangular cross section and three faces formed with different light transmitting properties, each of which is rotatably disposed in a space l4 formed between the hollow cylinders. It is composed of body 1. Two transparent plates 12 spaced apart via the spacer 16 described above. The multi-layer panel composed of 13 is, for example, double-glazed glass, double-glazed glass, etc. FIG. 1 is a sectional view showing an example of the structure of a hollow tube constituting the present invention. According to the same figure, a hollow cylinder l having three surfaces 2 has each surface 2 made of a transparent, translucent, or colored material such as a glass material or a resin material. For example, one surface of this base material has a light shielding function, the second surface has a heat ray reflecting function, and the third surface has a transmitting function. There is. That is, one of the surfaces 2 of the hollow cylindrical body l is subjected to a surface treatment that has a reflective function equivalent to a mirror surface, or
Light rays can be blocked by applying appropriate shielding treatments such as attaching a shielding sheet with a desired color, for example, applying paint, coating with a colored film, or coloring the base material itself. A shielding surface 3 is formed that does not allow transmission or only allows partial transmission. Further, on the second surface, a heat ray reflective surface 4 is formed by performing appropriate heat ray reflective treatment, such as forming a heat ray reflective layer by surface treatment or pasting a heat ray reflective sheet. Among these, when the heat ray reflective surface 4 is formed by providing a heat ray reflective layer by surface treatment, for example, a single layer of a heat ray reflective metal or alloy layer is placed on the substrate, or a layer of such a heat ray reflective metal or alloy layer and an upper layer is formed on the base layer. Two layers consisting of a protective layer or a transparent dielectric layer (e.g. TiO2.SnOz, ZnO
) / heat ray reflective metal or alloy layer (e.g. Ag,
Au, Cu, Cr, TiN, CrN, SuS
, NiCr, etc.)/transparent dielectric layer (for example, TiOi.
SnOi. ZnO 2 ) thin films can be formed by sequentially depositing each thin film using a vacuum evaporation method, an ion blating method, a sputtering method, or the like. In addition, when forming a heat ray reflective sheet by pasting it, for example, a heat ray reflective sheet formed by forming a constituent film constituting heat ray reflective properties as described above on a base film of polyester or nylon-6. etc., an appropriately configured structure can be used. Note that the third surface can be used as the transmitting surface 5 without any treatment on the base material. FIG. 2 shows the hollow cylindrical body 1 formed in this manner as shown in FIG. 13 is a cross-sectional view of a main part showing an embodiment in which they are rotatably arranged in a space 14 formed between 13 and 13. FIG. That is, two transparent plates 12. 13, when the diameter of the circular locus when the hollow cylinder rest 1 is rotated is a, and the width of the space l4 formed through the spacer l6 is b, the relationship is such that a<b. and are spaced apart from each other. In this way, two transparent plates 12. In the space 14 formed between the hollow cylinders 13, a plurality of the hollow cylinders 1 are rotatably arranged in either vertical or horizontal arrangement. In this case, each hollow cylindrical body 1 has one of its surfaces 2 as the transparent plate material 12. When the hollow cylinders 1 are rotated so as to be parallel to the transparent plates 12. Continuous surface 11 parallel to 13
The hollow cylindrical bodies 1 are spaced apart from each other so that the formation of the hollow cylindrical bodies 1 is possible. Moreover, the hollow cylinder 1 disposed in this manner is

On the other hand, a drive member l7 having a tooth groove 18 provided along its length is attached to the spacer l6 supporting the end cap 6 side on which the gear 8 is fixedly attached so that it can move forward and backward. The gear 8 of the end cap 6 is meshed with the tooth groove 18 of the drive member l7. In this case, the movement of the driving member l7 back and forth can be performed using an appropriate controllable driving body such as a piezoelectric linear motor. Note that the driving member l7 and the gear 8 having teeth 18

Further, the reference numeral 20 in the figure indicates a desiccant which is filled into the spacer 16 if necessary, and the reference numeral 21 indicates a sealing material. Since the present invention is configured in this manner, by simultaneously rotating each hollow cylinder 1 in the same direction by a required angle, an appropriate pattern formed by three surfaces having different transmission performance can be formed.

Since it can be confined within the space 14 sealed by 13, it can be kept in a variety of dimming patterns while reducing the causes of dirt and malfunctions, thereby reducing the need for maintenance and inspection work. It can be used as Moreover, since the forward and backward movement of the driving member 17 can be performed using an appropriate controllable driving body such as a piezoelectric linear motor, it is possible to move the driving member l7 forward and backward even when it is installed at a high place such as a skylight. However, you can freely operate it remotely.
