Abstract
A decorative venetian blind window security system that can be readily removed for emergency exit is disclosed. The security system includes a plurality of blind slats disposed within a frame assembly that receive locking rods through elongated openings formed in the blind slats. The locking rods can be selectively locked within the blind slats from the inside of the frame assembly. The blind slats can be selectively locked against rotational and transverse movement by locking means attached to the frame assembly.
