Inflatable ice igloo

Claim 1

A rapidly erectable shelter for subfreezing climes comprising: first means for enclosing a first shell-shaped chamber having a first fitting communicating therewith, said first shell-shaped chamber has a width sufficient to provide insulation and to reduce the problems associated with condensation on the inside of said rapidly erectable shelter; a source of pressurized gas coupled to said first fitting to distend said first enclosing means to define a first shell shaped chamber; second means for enclosing a second shell-shaped chamber having a second fitting communicating therewith, said second shellshaped chamber is sized to be larger than said first shellshaped chamber to be disposed adjacent to and supported by said first enclosing means when said first enclosing means is distended by said source of pressurized gas; the first enclosing means and the second enclosing means are flexible sheets shaped and arranged to form a three-walled, two-chambered hemispherical shell; and a source of water coupled to said second fitting for filling said second shell-shaped chamber, said water freezes to the solid state after being introduced into said second shellshaped chamber thereby forming the supporting structure for said rapidly erectable shelter while said first shell-shaped chamber serves to insulate and to prevent droplets from forming in the interior of said rapidly erectable shelter.
