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.

Foldable security bar assembly

A security bar assembly has a plurality of bars that extend across an opening and have ends joined to drive chains to provide an easily removable assembly. The bars extend between two channels positioned on opposite faces of the opening, and are slidable within the channels. The ends of the bars are retained in the channels and the ends have connections to chain links in opposing drive chains which are spaced apart a predetermined number of links to keep the bars a predetermined distance apart. A drive mechanism is provided for moving the drive chains to slide the bars in the channels and a storage area adjacent the opening associated with the channels to retain the bars when they are not in place over the opening.
