CA 2181991
A rollable or foldable structural mem- ber (11), which in its rolled out or laid out condition can take up support or pressure forces, and which comprises a number of in series arranged support means (12) and at least two flexible pull means (14) which link said support means, and by means of which a pressure force can be applied to the sup- port means for bringing them together and holding them together from a rolled up pas- sive condition to an erect, active condition. A number of channels (15) corresponding to the number of pull means (14) an arranged in the support means (12) and, where appli- cable, in between these arranged intermedi- ary parts (13), said channels running through said support means and intermediary parts, and being on one hand designed with a shape which is complementary to the cross section of the pull means along the entire length of the support means, on the other hand are ar- ranged at the largest possible distance from and substantially right opposite each other as seen in the bending plane of the structural member, The channels (15) are so dimen- sioned, that the pull means (14) are freely movable in their longitudinal direction.
Elément structural pouvant être enroulé ou plié (11) et susceptible, à l'état déroulé ou déplié, de résister à des forces de support ou de pression. Cet élément comprend un certain nombre de moyens de support disposés en série (12) et au moins deux moyens de traction flexibles (14) qui relient les moyens de support et qui permettent d'appliquer une force de pression aux moyens de support afin de les réunir et de les maintenir unis, en passant d'un état passif enroulé à un état actif dressé. Un certain nombre de canaux (15) correspondant au nombre de moyens de traction (14) sont ménagés dans les moyens de support (12) et, le cas échéant, dans des éléments intermédiaires (13) placés entre chaque moyen de support. Ces canaux passent à travers lesdits moyens de support et les éléments intermédiaires; ils présentent une forme complémentaire à la section transversale des moyens de traction sur toute la longueur des moyens de support, et ils sont placés le plus loin possible l'un de l'autre tout en se faisant face, vus dans le plan de pliage de l'élément structural. Les canaux (15) sont dimensionnés de sorte que les moyens de traction (14) puissent se déplacer librement dans le sens de la longueur.
