Abstract

L'invention concerne un corps de structure (3) suspendu en de multiples positions par des fils (15) depuis une section de support (11) formée au centre du corps de structure (3). Bien qu'il soit de structure simple, le corps de structure (3) ne se déforme pas. Etant donné que le corps de structure (3) a une structure simple, le poids de l'ensemble du dispositif est réduit. En outre, la tension est appliquée aux multiples positions du corps de structure (3) de dessous par les fils (15), et cela empêche le corps de structure (3) de se déformer même si le vent souffle contre une structure de miroir (5).
