L’invention concerne un dispositif de déploiement d’un corps creux de forme allongée présentant : au moins un corps creux allongé comportant deux demi-corps de coque allongés (2a, 2b) et pour première extrémité une racine, un mandrin (13) monté rotatif, sur lequel l’au moins un corps creux allongé est, dans un premier état, enroulé et comprimé, et dans un deuxième état, déroulé et déployé, de sorte qu’une cavité allongée (4) se forme entre les deux demi-corps, le premier demi-corps est fixé au mandrin rotatif dans la zone de la racine, un mécanisme d’expansion étant en prise avec le second demi-corps dans la zone de la racine, et écarte le second demi-corps du mandrin rotatif, afin d’assurer l’expansion de la section transversale de l’au moins un corps creux allongé dans ladite zone, quand ce dernier est déroulé du mandrin rotatif. Figure pour l’abrégé : Fig. 2
The invention relates to a device for unfolding a rolled-up elongate hollow member having:at least one elongate hollow member which has two elongate shell member halves, andan unfolding mechanism which has a fixed base structure and a winding core which is rotatably supported on the base structure and on which the at least one elongate hollow member in a first state is rolled up and compressed and which by rotating moves and unfolds the elongate hollow member from the first state into an unrolled and unfolded second state so that an elongate hollow space is formed between the two shell member halves of the at least one elongate hollow member,wherein the at least one elongate hollow member has as a first end a hollow member root, via which the elongate hollow member is secured to the rotatably supported winding core,whereinthe first shell member half of the at least one elongate hollow member is secured in the region of the hollow member root to the rotatably supported winding core, andthe unfolding mechanism has an expansion mechanism which in the region of the hollow member root is in engagement with the second shell member half and which moves the second shell member half in the region of the hollow member root away from the rotatably supported winding core in order to expand the cross-section of the at least one elongate hollow member in the region of the hollow member root when the elongate hollow member is unrolled from the rotatably supported winding core.
