| Abstract: |
An installation such as in the form of a building having a room or chamber in which an upward air flow is produced to levitate human beings. This installation, herein called a levitationarium, is constructed and arranged to be simple, safe and economic to operate in particular by comprising a blowing propeller that is shrouded and arranged to produce an induced suction flow in an annular air passage around it, under the action of the direct flow by the propeller inside the shroud; by having a toroidal air passage arranged for closed circuit streamline air flow serially through it and the levitation chamber; and by including a toroidal core portion interposed between the levitation chamber and the toroidal air passage and providing a spectator gallery and access to the levitation chamber.

What is claimed is:
1. A levitationarium for air flotation of humans comprising a housing having an inner wall defining a levitation chamber, said levitation chamber defining a central vertical axis and having an air inlet at the lower end thereof and an air outlet at the upper end thereof, shroud means supported within said housing proximate said lower end of said chamber with blower means arranged therein for propelling air upwardly through said shroud means and said chamber, said shroud means having an air inlet at the lower end thereof and an air outlet at the upper end thereof communicating with said air inlet of said chamber whereby said propelled air flow can be established, said shroud means being spaced from said inner wall an amount sufficient to cause a flow of air by the operation of said blower means resulting from both the blower means operation in driving air and an induced suction flow being produced in the space around said shroud whereby an enhanced air flow is generated in said chamber, flow directing means arranged in said shroud above said blower means for inwardly directing the flow produced by the driving of air by said blower means toward said axis of said chamber, grating means extending transversely across the lower end of said levitation chamber above said shroud means for simultaneously allowing upward air flow created by said blower means to pass therethrough and for supporting standing users of said levitationarium thereon, annular platform means extending peripherally around said inner wall of said levitation chamber and which is air impervious for permitting users to stand clear of said upward air flow and from which users can dive toward the center of said chamber for being lifted by said upward air flow, and deflector means arranged below said annular platform means and movable between an operating position and a non-operating position whereby when said blower means is in operation, said deflector means is forced into said operating position for deflecting air flow away from said platform means to prevent air turbulence in proximity thereto.
