Tornado or hurricane shelter

Abstract

The Invention relates to a tornado or hurricane shelter that is located above ground and at ground surface, large enough to provide a place of safety for up to ten people and is handicap accessible. The structures shape is oblong and a oblong spherical radius at the top. The basic frame and doors are solid thick hardwood planks bonded together with glue and fastened with lag screws and the windows are high impact plastic fastened to the structure with bolts. The door is a two part door with a sight window in the top, the side windows are removable from inside and they blend to the shape of the structure. High strength wire ropes go over the shelter and attach to turnbuckles which attach to earth anchors installed deep into the earth. Wire ropes and where it attaches to the earth anchors with turnbuckles is covered with a non metallic cover. The upper part door attaches to the lower door and the lower door attaches to the basic structure with heavy duty hinges and latches that are commercially available. A tornado can develop within half an hour or so with winds in excess of 200 miles per hour, while a hurricane can be tracked for a much longer time before it hits, dangerous lighting is present during tornadoes and hurricanes, Mobile homes, automobiles, trucks, and other weak structures should be avoided during these dangerous storms. It is important that people have a safe place to go within a close distance to where they live and work.

1 . I claim that the shape; the radius ends and the oblong spherical top of the basic structure  1 , and that the lower door  2 , the upper door  3 , and windows  4  and  5  blend to the shape of the basic structure  1 , and will let 250 miles per hour winds pass over and around it from any direction  
     
     
         2 . I claim that the solid thick walls and solid thick top of the basic structure  1 , the solid thick lower door  2 , and the solid thick upper door  3 , and the high impact plastic windows  4  and  5 , will stop a 2×4×10 foot long wood plank at 100 miles per hour and other flying objects and debris from entering the shelter at any location on the shelter.  
     
     
         3 . I claim that that the earth anchors  6 , connect to anchor rods  7 , and connected to the turnbuckle  8 , and connects to wire rope  9  will keep the shelter on its location when 250 miles per hour winds are pushing and pulling against it and when flying objects and debris are hitting it.  
     
     
         4 . I claim the materials used for the basic structure  1  is hardwood and the lower door  2  and upper door  3  is hardwood and windows  4  and  5  is high impact plastic, wire ropes  9  are placed in a groove in basic structure  1  and covered with rubber, where the wire ropes  9  connect to turnbuckle  8  and connect to anchor rod  7  is covered with a non metallic cover will give low attraction to lighting.
