Abstract

L'invention concerne une structure support en treillis comportant des barres en treillis reliées les unes aux autres. La structure support en treillis comporte des barres en treillis s'étendant dans la direction longitudinale de la structure, et des barres en treillis reliant celles-ci de façon directe ou indirecte. Les barres de liaison sont reliées aux barres longitudinales de telle manière que l'espace entre les barres longitudinales peut être réduit lors du repliement de la structure et augmenté lors du déploiement de la structure. Au moins une barre longitudinale est disposée fixe de manière à être stationnaire lors du repliement et du déploiement de la structure, et au moins une autre barre longitudinale est disposée mobile de manière à se déplacer lors du repliement et du déploiement de la structure.
