Rolling screen device for window

[Technical Field to which the Invention Affiliates] The present invention relates to a roll screen device mainly attached to a wide-area window of a high-rise building such as an office building for the purpose of shading.

[0002] [Conventional Techniques] As a roll screen device attached to a window having a wide opening area of a high-rise building such as an office building, Japanese Patent Application Laid-Open No. 62-185992, Japanese Patent Application Laid-Open No. 7-18959 or Although those shown in JP-A-8-14644 are known, all roll screen devices use cloth, synthetic resin film, etc. as the screen, and are generally used as window screens having light-shielding property and transparency. It is only used that has the properties required for the above, and there is a need for ergonomic improvement regarding light-shielding properties, transparency, stability of visual morphology / color tone, quietness, etc. , There is no place to disclose what kind of improvement means.

[0003] [Problems to be Solved by the Invention] A screen cloth for a roll screen, which is based on a cloth such as a woven fabric or a knitted fabric and has a synthetic resin layer formed on both sides in order to impart durability and weather resistance to the base cloth, is used. Not only does the screen surface on the indoor side generate so-called shine, which is the reflected light from the interior light, but when the base fabric is cloth, the roll screen has wavy or texture distortion such as curling and flare as the entire screen. It occurs on the surface and lacks morphological stability, and when viewed from the room, there are problems such as lack of visual stability and lack of quietness in terms of morphology and color tone. If the synthetic resin layer is made thicker, on the contrary, problems such as weight increase, cost increase, and different texture increase occur.

[0004] Further, in a usage environment exposed to direct sunlight, the durability and weather resistance due to the influence of ultraviolet rays become insufficient, and the selection of the type of fiber or synthetic resin is unreasonable, resulting in heat insulation and flame retardancy. There was a problem, and there was also a problem that the adjustment of light-shielding property and transparency by the screen cloth was not taken into consideration.

[0005] Therefore, in the present invention, although the cloth is based on a woven fabric, it is excellent in durability and weather resistance, has excellent reflection of external light, does not generate so-called reflective shine on the indoor side, and is a room. The texture of the fabric, especially the woven fabric, can be seen on the inside, so the degree of freedom in designing the design such as color and pattern is large, and the light-shielding property, transparency, and morphological stability as a screen cloth are excellent. While maintaining visual stability and quietness when viewed from the indoor side, it is also possible to adjust the light blocking effect and transparency, and to clean the screen surface, and it is relatively lightweight and excellent in ergonomics.<u style="single">, Can add heat insulation</u>An object of the present invention is to provide a roll screen device for windows.
