This invention relates to armor systems for protection against various safety issues such as might be experienced with a typical tornado, hurricane or even against ballistic projectiles in terrorist or criminal situations, in particular, ballistic panels that can be easily and quickly locked together to form buildings, rooms or other enclosures such as a “safe” room.
Given current economic conditions and the level of terrorist activities at home and aboard as well as the current cycle of more frequent severe weather, the need for rapidly deployable, lightweight, cost effective protection has reached an all time high. While conventional armament such as steel plates provide sufficient protection, weight, cost and difficulty in installation, this choice of conventional armament impractical except in military situations.
U.S. Pat. No. 7,921,759, issued to Warren on Apr, 12, 2011, is directed towards providing a ballistic panel that is useful for protecting military vehicles in battle conditions for protection against enemy fire. This patent teaches the use of a panel comprising multiple layers having a grinding layer including ceramic spheres. Not only is this construction very expensive to achieve, there is no provision for easily attaching these panels to one another.
There is not found in the prior art, a ballistic panel that is inexpensive to construct, quickly and easily attached together to form an enclosure, and light enough to use in residential environments.
It is an aspect of the invention to provide a ballistic panel that is fabricated from polyurethane foam that provides protection without the weight of prior art armaments.
It is still another aspect of the invention to provide a ballistic panel that uses ballistic resin/fiber material such as KEVLAR to provide protection.
Another aspect of the invention is to provide a ballistic panel that has cam locks that enable one panel to be quickly and easily attached to an adjacent panel.
It is another aspect of the invention to provide a ballistic panel that uses lightweight outer skins to provide the structure of the panel.
A further aspect of the invention is to provide a ballistic panel that also has a high insulation R-value such that the panel can be used for refrigerated storage or in high heat situations.
Finally, it is an aspect of the invention to provide a ballistic panel that can be locked together to provide an enclosure such as a room or even a building.
As shown in
The core of foam 16 of the ballistic panel is made from polyurethane foam. Polystyrene foam could also be used. Foam layer 16 is preferably poured in place with high-pressure foam machines. Thicknesses could range from 1 inch to up to 6 inches thick. Foam layer 16 provides the structure of panel 10 and acts as a binder to hold ballistic rated material layer 18 and cam locks 19 in place.
As noted, invention panel 10 is especially useful for insulation purposes. Each inch of foam thickness provides an R-value of 8. Thus, panel 10 is ideal for use in refrigerated storage situations. It is also ideally suited for use in modular buildings and enclosures where extreme hot or cold climate conditions are expected.
Ballistic rated material layer 18 is preferably made from KEVLAR, E.I. Dupont's trademarked identification for its para-aramid synthetic fiber. However, other ballistic materials such Ballistic Ceramics, DYNEMA, a high strength polyethylene fiber, tempered steel or ballistic fiberglass phenolics, PBO fibers as well as other ballistic materials could be used as well.
Ballistic layer 18 is adhered to the outer skin by high strength construction adhesive and is held permanently in place when the foam is injected into the panel during the manufacturing process. The thickness of ballistic layer 18 will be determined by the threat level to panel 10 that is expected.
