Window with obscuring elements applied to glass sheets that allows an instantaneous transition from translucency to opacity

摘要

The system consists of a pair of glass sheets placed in contact with each other of which one is fixed and the other capable of an also minimum vertical or horizontal excursion respect to the first, moving from a position "A" to a position "B" and vice versa. The two sheets are suitably serigraphed according to a drawing which allows a transparency of 40% when the sheets are in position "A" and the total opacity when the sheets are in position "B".
