inflatable structure

(redirected from Joy Jump)

pneumatic structure

A very lightweight enclosed structure, usually fabricated of a membrane of an impervious material and supported by the difference in air pressure between the exterior and the interior of the structure rather than by a structural framework. Fans must maintain the interior pressure slightly in excess of normal atmospheric pressure to prevent the structure from slowly deflating and collapsing. Used primarily as a temporary enclosure or to house sports facilities such as tennis courts and swimming pools. Also called an air-supported structure.
