Portable shelter

Abstract

A shelter provides protection against airborne contaminants such as, biological, chemical or radioactive agents. The shelter includes an isolating unit having impermeable panels, frame members and at least one entrance. The shelter further includes an occupant interface to the exterior and at least one control interface. In addition, a method for protecting occupants against threats within the inner space of a chamber is provided.

1 . A portable shelter for protecting occupants against an airborne threat, comprising: 
 an isolating unit comprising: 
 impermeable panels;  
 frame members;  
 at least one entrance;  
   an occupant interface to the exterior, and    at least one control interface.    
     
     
         2 . A portable shelter for protecting occupants against a threat as in  claim 1  and wherein at least one of said impermeable panels contains at least one window sheet.  
     
     
         3 . A portable shelter for protecting occupants against a threat as in  claim 1  and wherein said frame members become rigid upon inflation.  
     
     
         4 . A portable shelter for protecting occupants against a threat as in  claim 1  and wherein said control interface is associated with said occupant interface to the exterior.  
     
     
         5 . A portable shelter for protecting occupants against a threat as in  claim 1  and wherein at least one control interface is disposed in the outside of said isolating unit.  
     
     
         6 . A method for protecting occupants against threats within the inner space of a chamber, comprising the steps of; 
 unfolding a portable shelter;    erecting a chamber construction by inflating frame members of said chamber, and    implementing control over sustenance elements of said shelter.    
     
     
         7 . A method for protecting occupants against threats within the inner space of a chamber as in  claim 6 , and wherein a control is implemented over air pressure.
