Disaster shelter and shelter system

Abstract

A disaster shelter and disaster shelter system. The disaster shelter includes a substantially hollow shelter cell having an interior and an exterior. The shelter cell is made up of three parts; a shelter body, an end cap section and an entranceway section. The shelter body is made up of a plurality of cell sections, each having a substantially identical double elliptical toroid shape, with the endmost cell sections forming an entrance end and a cap end respectively. The end cap section is joined to the cap end of the shelter body an entranceway section is joined to the entrance end of the shelter body. An entranceway is attached to the entranceway section of the shelter cell.

 an end cap section joined to said cap end of said shelter body; and 
 an entranceway section joined to said entrance end of said shelter body; and 
   an entranceway attached to said entranceway section of said shelter cell.   
     
     
         2 . The disaster shelter as claimed in  claim 1 , wherein said entranceway comprises an elliptical entranceway attached in non-perpendicular relation to said shelter body. 
     
     
         3 . The disaster shelter as claimed in  claim 1  wherein said entranceway comprises a sliding hatch cover. 
     
     
         4 . The disaster shelter as claimed in  claim 3  wherein said entranceway comprises an elliptical hatch dome ring having a slide pocket disposed therein, wherein said sliding hatch cover and said slide pocket of said hatch dome ring are each dimensioned to allow said sliding hatch cover to slide within, and be retained by, said slide pocket. 
     
     
         5 . The disaster shelter as claimed in  claim 4  further comprising a reduced friction material disposed upon one of said sliding hatch cover and said slide pocket, said reduced friction material having a substantially low coefficient of friction. 
     
     
         6 . The disaster shelter as claimed in  claim 4  further comprising an expanding rod removably attached to said hatch dome and said sliding hatch cover, wherein said expanding rod is dimensioned to force said sliding hatch cover to slide within said slide pocket when said expanding rod is expanded. 
     
     
         7 . The disaster shelter as claimed in  claim 6  wherein said expanding rod is a ratchet expanding rod comprising a ratchet mechanism and a handle. 
     
     
         8 . The disaster shelter as claimed in  claim 1  further comprising a seismic joint connecting said entranceway to said entrance section of said shelter cell. 
     
     
         9 . The disaster shelter as claimed in  claim 8  wherein said seismic joint is a triple axis seismic joint that is dimensioned to allow said entranceway to move in any direction relative to said shelter cell. 
     
     
         10 . The disaster shelter as claimed in  claim 1  further comprising a shelter floor disposed within said shelter cell, wherein said shelter floor is not attached to said shelter cell. 
     
     
         11 . The disaster shelter as claimed in  claim 10  further comprising a plurality of floor joint brackets attached to said interior of said shelter cell, wherein said shelter floor comprises a plurality of floor planks, and wherein said floor joint brackets are disposed and dimensioned to support said plurality of floor planks. 
     
     
         12 . The disaster shelter as claimed in  claim 1  wherein said shelter cell comprises a bathroom having a mixing exhaust manifold in communication therewith, wherein said mixing exhaust manifold is adapted to take in gasses from both said bathroom and a remainder of said shelter cell and exhaust said gasses from said shelter cell. 
     
     
         13 . The disaster shelter as claimed in  claim 1  further comprising an air filtration system disposed within said entranceway. 
     
     
         14 . The disaster shelter as claimed in  claim 13  wherein said air filtration system comprises an air inlet pipe, a pre-filter, a gas agent test port, a HEPA filter, an ultraviolet light and a blower, wherein each of said pre-filter, gas agent test port, HEPA filter, and ultraviolet light are in fluid communication with said air inlet and said blower. 
     
     
         15 . A disaster shelter comprising:
 a substantially hollow shelter cell having an interior and an exterior;   an entranceway; and   a triple axis seismic joint that connects said substantially hollow shelter cell to said entranceway, wherein said triple axis seismic joint is dimensioned to allow said entranceway to move relative to said shelter cell in all directions except rotation.   
     
     
         16 . A disaster shelter system comprising:
 a substantially hollow shelter cell having an interior and an exterior;   an entranceway attached to said shelter cell;   an entranceway anchor;   a cable attaching said entranceway to said entranceway anchor; and   a cable tension adjuster attached to said cable, wherein said cable tension adjuster is dimensioned to absorb shock imposed upon said entranceway;   wherein said cable tension adjuster comprises a substantially convex dome comprising a top half, a bottom half and a substantially flexible center donut plate, wherein said center donut plate comprises a first cable attachment, wherein said bottom half comprises a second cable attachment, and wherein said top half comprises an opening therethrough dimensioned to allow said cable to pass therethrough and attach to said first cable attachment.   
     
     
         17 . (canceled) 
     
     
         18 . The disaster shelter system as claimed in  claim 16  wherein said shelter cell further comprises a toilet and wherein said shelter system further comprising a leaching s septic tank disposed a distance away from said shelter cell and n fluid communication with said toilet.
