Abstract
A foldable security bar assembly, is convenient, aesthetic and less costly than existing security systems, and is used primarily for security rather than a shutter assembly. The assembly is for placing over or in an opening and has a plurality of horizontal bars extending between two channels, the two channels positioned one on each side of the opening with the bars slidable vertically within the channels. A plurality of connector links join adjacent bars together with at least one of the bars having a connection at each end within the channels to a raising and lowering mechanism in each channel coordinated to raise and lower the at least one bar and hence the whole assembly. A drive system is provided for the raising and lowering mechanism, and guides above or below the channels guide and retain the horizontal bars in a folded configuration above or below the opening with alternate bars on opposite sides.
