Definitions
- the present invention relates to a blind having an element for forming an excellent indoor atmosphere as an interior article.
- blinds are used for dimming to adjust the amount of light rays entering the room from the opening of the building, or for shading to block the light rays entering the room.
- the demand for comfortable living spaces requires not only such dimming and shading functions in the blind but also elements that create a better indoor atmosphere. It is. For this reason, various measures have been taken, such as reducing the width of the slit to make the appearance lighter, and softening the color softly, but it is satisfactory. Absent.

- each of the parallelly arranged slats is rotatable at the same time about its long axis, and each of the slats has a figure forming part on a transparent material substrate.
- the substrate has a central surface and a first bent surface which is bent obliquely upward from one side edge to the central surface in a cross-sectional view in a direction transverse to the long axis.
- a second bent surface that bends obliquely downward from the other side edge, and the drawing portion of each slot is tilted at a predetermined angle by rotation of each slot.
- the figure-forming part is a part formed of a light-shielding paint or film, and the meaningful figure is a combination of the other part with the figure-forming part of the blind. As a whole, it is a figure that is formed and that the observer in the room receives some impression through his / her sight. This figure can be projected onto the floor or wall by light rays from the back of the blind (projection type), or the reflected light from the drawing area can be applied to the entire blind. There are types of figures to be formed (direct view type).
- Slit board has when blinds are closed When a meaningful figure disappears due to the figure-forming part, the meaningless or unpleasant pattern due to the figure-forming part is conspicuous. Sometimes you don't get it.
- the invention according to this application uses the transmission or reflection of light rays (diffuse reflection, total reflection) positively and has the creativity of a fresh indoor atmosphere that is not available in conventional blinds.
- the present invention aims to provide a blind that does not impair the dimming and shading functions.
- the purpose of the present invention is to make it possible to change a meaningful figure created by the drawing part of the slit substrate without replacing the blind.

- one invention of this application is configured as follows.
- the blind is formed such that each of the parallelly arranged slits is rotatable all around its long axis.
- Each of the slits has a figure forming portion on a transparent material substrate.
- the substrate In the cross-sectional shape in the direction transverse to the major axis, the substrate has the first bent surface and the other bent edge bent obliquely upward from the center surface and one side edge to the center surface. And a second bent surface that bends obliquely downward.
- the figure forming part is formed by providing a diffuse reflection surface consisting of fine irregularities on a part of the surface of the substrate.
- the blinds of this configuration are designed so that when the slats are tilted to a predetermined angle, the shaded parts (projections) formed in combination with the other slats' figure forming parts (Type) or a reflection part (direct-view type) due to diffuse reflection forms a figure that is meaningful to the observer as the whole blind.
- the light-blocking part blocks the light from the back of the blind and creates a shadow on the wall or floor (projection).
- the part reflected by diffuse reflection reflects light from the observer side. Let the observer recognize the figure.
- the predetermined angle of each slot is the angle at which a meaningful figure appears most clearly due to reflection on the blind surface, or projected onto a wall or floor. This is the angle at which a meaningful figure appears most clearly. This angle is appropriately determined according to the direction of the line of sight of the observer, the direction of the light beam from the indoor side (observer side), and the outdoor side.
- the figure formation part is formed on the part of the surface of the substrate with irregular reflection surface consisting of fine concave and convex, so it is clearly visible on the wall or floor by the transmitted light from the back of the blind.
- the reflected light from this surface is soft white, while the projection is made, so even if a meaningful figure disappears, such as when the blinds are closed, the figure-forming part will be noticeable. There is no. Therefore, even if a meaningful figure has disappeared from the blind, the atmosphere in the room is not destroyed.

Significant figures are projected by the rays from the back of the blind being blocked at the drawing part, or by reflections from the blind forming part (diffuse reflection, total reflection). Formed.
- the leading edge of the second bent surface is aligned with the center surface and the second bent surface. Since the connection is closer to the center than the connection of the curved surface, the rotation of the slot when closing the blind is high with the first bending surface centered on the long axis and the second bending.
- the surface is lowered, no matter which surface of the blind faces the observer, the light from the observer toward the blind is the surface of the substrate other than the part where the slit is formed. It does not reach the observer after being reflected by the. Thus, when a meaningful figure is obtained by direct viewing, the figure is not disturbed by unnecessary reflected light from the substrate surface.
