Pivoting venetian blind for different situations 
Venetian blinds allow filtering sunlight by directing their slats, when it is lowered, without obstructing the outside view. They are a widely used solution in offices and public facilities, but is easily applicable to private uses.
This case is characterized for the horizontal independence between three zones of louvers, depending on the height from the ground. Being able to independently regulate these three areas of the blind, as once was done in the classic folding-sliding shades. It allows perfect adaptation to solar incidence for any interior area, and adapt it to its use.
Being able to close the bottom allows us to avoid dazzling while the top can continue allow the entrance of sunlight.
