Tent

Abstract

An insulated tent which has interior and exterior walls that are separated from each other by an atmosphere of low thermal conductivity. The atmosphere may be a partial vacuum or may include a gas with lower thermal conductivity than air. The walls may be kept separate by the pressure of the gas or by mechanical forces and the partial vacuum may be induced by means of a one-way valve which permits the escape of heated air from between the interior and exterior walls. Also disclosed are structures that reduce the effect of wind on the tent's exterior surface, including spoilers and convex windward edges, and structures that guide the flow of water on the interior and exterior surfaces of the tent.

1 . A tent, the tent being characterized in that:
 the erected tent has a wall including
 an interior membrane, 
 an exterior membrane, and 
 an internal gap between the interior membrane and the exterior membrane, the internal gap containing a thermally insulative atmosphere.
