Abstract
Abstract An underground blast shelter providing short and long term protection against nuclear detonation for its occupants. The shelter consists of a paraboloidal cell to house the occupants and a command station interfacing with the ground surface. A flange completely surrounds the cell along its long dimension. The command station is made from an upper portion made out of steel and a lower portion which is a part of the flange of the cell. Access between the command station and the cell is through the flange and includes foot wells to facilitate movement.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
209 words
An underground nuclear blast shelter comprising: a. elongated cell means below ground level containing living space for one or more occupants of said shelter; b. underground command station means located above one end of said cell means having a dome at ground surface and passageway means extending directly down into the cell means for providing access through the bottom of said command station means to said cell means, said dome being the only visible portion of said shelter; c. said cell means comprising a pair of matching elongated clam shaped elements having matching rims extending along the edges thereof, said matching rims bonded to each other to form a flange completely encompassing said cell means along the long dimension thereof; d. said command station means comprising a lower portion formed within and being an integral part of said flange formed by said clam shaped elements, said flange extending above the cell means, and an upper portion extending above said flange, means joining said upper and lower portions of said command station means to form an enclosed area; and e. said passageway within and being an integral part of said flange formed by said clam shaped elements to provide said communication between said command station means and said cell means.
Claim 2
Dependent Claim
209 words
An underground nuclear blast shelter comprising: a. elongated cell means below ground level containing living space for one or more occupants of said shelter; b. underground command station means located above one end of said cell means having a dome at ground surface and passageway means extending directly down into the cell means for providing access through the bottom of said command station means to said cell means, said dome being the only visible portion of said shelter; c. said cell means comprising a pair of matching elongated clam shaped elements having matching rims extending along the edges thereof, said matching rims bonded to each other to form a flange completely encompassing said cell means along the long dimension thereof; d. said command station means comprising a lower portion formed within and being an integral part of said flange formed by said clam shaped elements, said flange extending above the cell means, and an upper portion extending above said flange, means joining said upper and lower portions of said command station means to form an enclosed area; and e. said passageway within and being an integral part of said flange formed by said clam shaped elements to provide said communication between said command station means and said cell means.
