ABSTRACT:
A self-supporting inflatable structure useful, for example, as an inexpensive, readily assembled planetarium, such structure being made of an extensible material having a plurality of panels, each shaped so as to form, when inflated, a hemispherical dome-like structure. A first channel, also made of extensible material is used to supply air, as from an inexpensive, conventional window fan for inflating the structure and a second channel permits the exit of such air in a controlled manner while at the same time acting as an entrance/exit channel for persons using the inflated chamber.
The extensible material is preferably formed of co-extruded, or laminated, opaque plastic sheets, one sheet having a white surface for use as the interior display surface of the planetarium and one sheet being black to prevent light entry into the chamber. The air input and exit channels have a curved configuration which prevents light from entering into the inflated chamber. Such a structure can also be used for many other purposes, both educational or recreational, for example.
