Abstract
To enhance or ensure personal security against an attack, threatened attack or believed attack, a flexible drop net, preferably made of ball chain elements (26, 30), connected at nodal points (28) is retained against and/or partly within a dropped or double-wall ceiling (2, 3). The drop net is held against the ceiling by a pull-up or raising chain, preferably also a ball chain (13), and pulled up by a lifting mechanism (18), for example rollers, engageable with a pull chain and operated by a motor, if desired. A triggering mechanism is coupled to a retention rail or plate (5) holding the drop net or at least a portion thereof within the double ceiling, against the drop rail or plate, or thereabove. Upon a triggering impulse being applied to an electromagnet (6), a linkage (7, 9) releases the drop rail or plate, thus dropping the flexible net over an attacker; any other persons, who are also within the range of the net, will likewise be trapped thereunder, without, however, causing injury.
