Patent number: 8613242Abstract: The present invention is directed to methods of manufacturing Anti-ballistic Shelters such as Quonset buildings or huts, tents, pipe, rod, tubular and other frame structures, doors, room dividers, cots, pads and umbrellas using soft armor fabric or hard armor materials. Soft armor consists of flexible high-strength layered anti-ballistic material attached to a frame and layered in at least two directions. Soft armor requires an area of flexibility or expansion to work effectively when struck by a projectile along with a very secure attachment. With the design disclosed within this application the soft armor fabric is affixed to frameworks by an inverted âTâ fabric construction method or which allows the flexibility or expansion required for maximum anti-ballistic protection within the shelter.Type: GrantFiled: October 24, 2012Date of Patent: December 24, 2013Assignee: Peters Security International, Inc.Inventor: Fred E.
