Security barrier

Abstract

An apparatus and method for installing and deploying a barrier utilizing one or more gas generators. The invention includes a barrier component installed beneath the ground surface or substantially parallel to the ground and raised by activation of the gas generator. The device can be trigger automatically without human intervention and thereby faster deployment of the barrier. The barrier can include a reactive component. The barrier can include plurality of telescoping barrier subcomponents.

1 . A cylindrical barrier comprising: 
 a) a first cylinder installed substantially below a ground surface plane and said cylinder having an axis of orientation substantially normal to the plane of the ground surface;    b) a cylindrical barrier comprising a second cylinder substantially within the first cylinder and having the same axis of orientation of the first cylinder;    c) a gas generator to move the cylindrical barrier along the axis of orientation in a manner that the cylindrical barrier extends from the second end of the first cylinder and above the plane of the ground level; and    d) a mechanism to retain and lock the cylindrical barrier to the first cylinder after activation of the gas generator.    
   
   
       2 . The barrier of  claim 1  wherein the cylindrical barrier contains a reactive barrier.  
   
   
       3 . The barrier of  claim 1  further comprising guide grooves or protrusions in an inner wall of the first cylinder and complementary guide grooves or protrusions in the outer wall of the cylindrical barrier.  
   
   
       4 . The barrier of  claim 1  further comprising a mechanism to activate the gas generator.  
   
   
       5 . The barrier of  claim 4  wherein the mechanism activating the gas generator comprises an RF signal.  
   
   
       6 . A barrier comprising: 
 a) a barrier component comprising at least one nested cylinder having a longitudinal axis of orientation extending out of a ground surface plane;    b) a gas generator to move the barrier component along the axis of orientation in a manner that the barrier component extends from a first cylinder and above the plane of the ground level;    c) a structural support member pivotally attached to the barrier component; and    d) a connecting component extending along a ground surface attached to the first cylinder and pivotally attached to the structural support member.    
   
   
       7 . The barrier of  claim 6  wherein the barrier component comprises a reactive barrier.  
   
   
       8 . The barrier of  claim 7  wherein the reactive barrier comprises a second gas generator.  
   
   
       9 . The barrier of  claim 7  wherein the reactive barrier comprises an explosive.  
   
   
       10 . A barrier comprising: 
 a) at least one first outer structure having a longitudinal axis of orientation and a first end and a second end;    b) a barrier component comprising a second inner structure located at least partially within the first structure and having a top and the same longitudinal axis of orientation as the first structure and mechanisms to retain and lock the second structure to the first structure; and    c) a gas generator to move the barrier component along the longitudinal axis of orientation in a manner that the barrier component extends from the second end of the first structure.    
   
   
       11 . The barrier of  claim 10  further comprising a mechanism to activate the gas generator.  
   
   
       12 . The barrier of  claim 11  wherein the mechanism activating the gas generator comprises an RF signal.  
   
   
       13 . The barrier of  claim 10  wherein the longitudinal orientation of the extended barrier component is at least 45 degrees to the plane of the ground level.  
   
   
       14 . The barrier of  claim 10  wherein at least a portion of the barrier system is located below the ground surface level.  
   
   
       15 . A method of deploying a barrier comprising: 
 a) activating a gas generator; and    b) using the expanding gas to move a barrier component from a first position to a second position wherein the barrier component consists essentially of a cylinder having a top and a mechanism to retain and lock the barrier component to another component.    
   
   
       16 . The method of  claim 15  further comprising transmitting an RF signal from a remote sensor to a gas generator activation mechanism.
