  • Venetian blind profiled slats
    Patent number: 3971427
    Abstract: A venetian blind is provided having the usual plurality of slats. Each slat is profiled transversely of its length such that it has a central section and pair of edge sections. The control section is substantially flat and is inclined at an angle to a plane which passes through the outer edges of the edge sections whereby the blind can be completely closed without the necessity of tipping the central sections of the slats as far as in previous constructions.
