Rapid deployment anti-ballistic shelter
Methods and apparatus are provided for a ballistic resistant shelter configured for emergency deployment in an open space. The shelter has a structural frame configured to rapidly convert from a stowed condition disposed substantially flat on the ground, to a deployed condition in which the frame is elevated substantially above ground level. One or more anti-ballistic panels are attached to the frame so as to be tilted or lifted above ground level when the frame is deployed. The anti-ballistic panels collectively present enough surface area to shield at least one person from a single source of gunfire.
1. A ballistic resistant shelter configured for emergency deployment in an open space, comprising:
a structural frame configured to rapidly convert from a stowed condition disposed substantially flat on the ground, to a deployed condition in which the frame is elevated substantially above ground level, wherein the structural frame is a metal construction with a base, a moving portion, and a linkage disposed between the base and moving portion;
one or more rigid anti-ballistic panels attached to the frame so as to be tilted or lifted above ground level when the frame is deployed, wherein the one or more rigid anti-ballistic panels collectively present enough surface area with the frame in the deployed condition to shield at least one person from a single source of gunfire; and
an actuator configured to cause the frame to rapidly convert from the stowed condition to the deployed condition.
2. The ballistic resistant shelter of claim 1 , wherein the structural frame comprises a plurality of inflatable beams, and the actuator comprises a rapid inflation device.
3. The ballistic resistant shelter of claim 2 , wherein the rapid inflation device comprises one or more pyrotechnic or compressed air gas generator devices.
4. The ballistic resistant shelter of claim 2 , wherein the one or more anti-ballistic panels are attached to the inflatable beams and positioned immediately adjacent or overlapping one another to form a substantially uninterrupted protective surface when the beams are inflated.
5. The ballistic resistant shelter of claim 1 , wherein the one or more anti-ballistic panels are a layered construction comprising a strike plate, and a backing made from high strength ballistic fibers.
6. The ballistic resistant shelter of claim 1 , wherein the actuator is a hydraulic or linear screw device connected between the base and the linkage, that when extended causes the moving portion of the frame to be raised.
7. The ballistic resistant shelter of claim 1 , wherein the moving portion of the frame is configured to translate vertically upward when the actuator is extended, and the one or more anti-ballistic panels comprise at least two hinged panels configured to unfold when the moving portion translates upward.
8. The ballistic resistant shelter of claim 6 , wherein the one or more anti-ballistic panels comprise a single panel attached to the moving portion of the frame, and where extending the actuator causes the single panel to tilt upward.
9. An inflatable ballistic resistant shelter configured for emergency deployment in an open space, comprising:
a structural frame comprising a series of inflatable beams configured to be rapidly deployable from a deflated condition disposed substantially flat on the ground, to an inflated condition in which the frame is elevated substantially above ground level, wherein the series of inflatable beams are interconnecting segments that form a dome shaped structure with openings between the segments; and
one or more triangular anti-ballistic panels attached to the frame so as to be tilted or lifted above ground level when the frame is deployed, wherein the one or more triangular anti-ballistic panels together present enough surface area when the frame is in the inflated condition to shield at least one person from a single source of gunfire, and wherein the openings are covered by the triangular anti-ballistic panels that collectively form a substantially uninterrupted surface on the outside or inside of the frame.
10. The inflatable ballistic resistant shelter of claim 9 , wherein the frame is capable of retaining at least 90 percent of an inflation pressure in the range of 5 to 30 pounds per square inch for at least one hour.
11. The inflatable ballistic resistant shelter of claim 9 , wherein the shelter in the inflated condition is between 10 and 20 feet across at the base, and 7 to 12 feet high at the center.
12. The inflatable ballistic resistant shelter of claim 9 , wherein the shelter in the inflated condition is large enough to hold groups of between 20 and 100 people.
13. The inflatable ballistic resistant shelter of claim 9 , wherein the series of inflatable beams are straight segments extending outward and downward from a central apex in the manner of a teepee.
14. The inflatable ballistic resistant shelter of claim 9 , wherein the series of inflatable beams are two separate segments, each in the shape of a triangular loop with a center opening, and wherein the one or more anti-ballistic panels are two rectangular panels leaned toward one another in the manner of a pup tent, connected at opposite ends to the inflatable beams.
15. The inflatable ballistic resistant shelter of claim 9 , further comprising a rapid inflation device connected to the frame through a one-way valve.
16. The inflatable ballistic resistant shelter of claim 15 , wherein the rapid inflation device comprises a high volume blower, or one or more pyrotechnic or compressed air gas generator devices.
