ABSTRACT:
A window bar security system has a grill of bars positioned outside a building window and held by a plurality of standoffs. Two of the standoffs are latching standoffs and extend from opposite sides of the grill through the wall and into the building and each latching standoffs includes a hole at the distal end. Four other guiding standoffs are inserted into receptacles against coil springs and the four guiding standoffs are positioned in pairs on opposite sides and equi-distant from each latching standoff. A pair of sliding bolt mechanisms are affixed to the inner wall of the building and positioned to permit the sliding bolt of each to fit into one of the latching standoff holes and to be moved towards the center of the window to release the latching standoffs. A pair of security pins are provided with one end designed to fit into a sliding bolt mechanism for preventing the unintentional movement of the sliding bolt and with another end shaped in the form of a hook. Each pin is tied by a string to a sliding bolt and the string is of such a length to permit the hooks of the two pins to be fastened together and still maintain the strings generally horizontal. To release the grill, the affixed strings are pulled to simultaneously move the sliding bolts out of the latching standoff holes. The pins and sliding bolt mechanism may be connected to an electronic security system.
