Abstract

The tent herein comprises outer nonporous and inner porous layers disposed in spaced relation to each other, with a continuous air passageway therebetween. Compression tent supporting means comprises a plurality of demountable, substantially, semicircular rods, preferably formed of fiber glass, forming arched rafters, and of a plurality of relatively short pieces slidably interconnected to form two rod units. These two rod units are interconnected by a sleeve, slidably mounted on one unit, to slidably receive the end portion of the other. The arched rafters are spaced apart and alined substantially parallel to each other and progressively decrease in diameter in a tent longitudinal direction. An inner tent layer is suspendedly supported by an outer layer by porous netting strips. At the end portions, nonporous, substantially semiannular shaped end members are provided which extend radially inwardly and angularly between the inner and outer tent layers. At the end portions, the outer tent layer is under tension by opposite, outwardly directed forces. All of the forces holding the tent in place are tension forces except forces acting through the tent rod units which are compression forces. All heat generated within the tent, such as that formed by human breathing or by the burning of a candle, rises upwardly in the tent and passes through the inner tent layer, thence longitudinally through the passageway between the inner and outer tent layers and thereafter out through the tent end portions by way of breather passageways disposed in end portions of the tent.
