Abstract (en)
[origin: EP0043762A1] 1. An inflatable structure having an opening (3) and a substantially hemispherical shape, this structure being constituted of an inflatable wall (2) and of tubes (5) which are equally inflatable and which are disposed along meridians, and comprising a stationary part (2) and a mobile part or curtain (3) for obturating the opening, characterized in that in the stationary part constituted of a spherical summit part (7) or umbrella superposed to a portion of a spherical crown (A-B), th tubes which are substantially cylindrical and constitute beam are attached to the wall through their lower generatrix line along portions of meridians (9) located under the summit part as well as on the crown portion, and are diposed in such a way that the substantially cylindrical and circular tubes (5) which are separated from one another in the lower zone of the structure corresponding to the crown portion, become adjacent to each other and ovalised at the height of a parallel plane (6) situated adjacent to the summit part (7) of the structure and delimiting the contour of said spherical summit part in such a way that said tubes lean against each other for developping radial as well as tangential forces which are transferred into the wall to which they are attached.
