摘要:
A bistable tubular (24) is formed with a number of cells (23) having a thin strut (21) connected to a thicker strut (22). The struts (21, 22) may be pivotally connected by use of pin joint or a ball and socket joint. Various locking mechanisms (Figs 35A-35D, 36A-36D, 37, 38A-41B) are disclosed and are used to keep the cells (23) in the expanded position. One such locking mechanism includes a ratchet post (264) which makes interfering engagement with a corresponding post (260) and prevents contraction of the tubular (24).En ekspanderbar anordning omfatter et flertall av ekspanderbare celler. Cellene kan være bistabile celler eller andre typer av celler som er ekspandert fra en sammentrukket posisjon mot en ekspandert posisjon. I tillegg kan cellene være kombinert med låsemekanismer for å holde konstruksjonen i en ekspandert posisjon.
