Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind device which is arranged in a window of a building and, if necessary, blindfolds the window and the like.

[0002]

In this type of blind apparatus, usually, a blind composed of a plurality of slats juxtaposed in the vertical direction is arranged above, and the blind is lowered from above by the operation of an elevator. It is configured such that an opening such as a window is blindfolded, and the blind is raised by the reverse operation of the elevating device to open the opening.

[0003] In such a blind device, as described above, when the opening is opened, a plurality of slats constituting the blind are arranged above the opening, usually in a state of being closely overlapped with each other. Even when the opening is fully opened, the opening is partially closed by the polymerized slat, and when the opening is fully opened, a sufficient release feeling cannot be enjoyed, which is annoying. Even if the slat storage frame is provided above to eliminate this, the occupied space for the slat storage frame is required above, and this may be difficult in general houses, buildings, etc.
It is not always satisfactory. In addition, for example, when it is desired to perform blindfolding only under the opening, there is a problem that the conventional blind device cannot perform such a blinding operation.Furthermore, slats must be cleaned using a ladder, a table, or the like. There is also a risk that an object or a person will be pinched by the lowering of the blind in the closing operation.

In view of the above, a plurality of slats constituting the blind are opened below the opening when the opening is opened, and the slats are lifted via a link mechanism when the opening is closed. A device has been proposed, and the proposed blind device can preferably solve the above-mentioned various problems, and in that respect it is satisfactory, but such a blind device can be provided in each of the windows of a building lined sideways. When juxtaposed, it is required to reduce the space between the blind device and the blind device in relation to the column width.
