Collapsible roll-out truss

摘要

Collapsible support structures and methods of making collapsible support structures which interconvert between a deployed condition and a collapsed planate condition which allows extensible retractable deployment of the collapsed structure from a reduced volume rolled condition.

主权项

1. A collapsible structure, comprising:
four longerons each having a longeron length disposed between a longeron first end and a longeron second end, said four longerons each configurable along said longeron length between a longeron flat condition having opposed longeron external and internal flat surfaces disposed between a pair of longeron longitudinal edges and a longeron tubular condition having opposed longeron external and internal curved surfaces disposed between said pair of longeron longitudinal edges; and a plurality of cross members each having a cross member length disposed between a cross member first end and a cross member second end, said plurality of cross members each configurable along said cross member length between a cross member flat condition having opposed cross member external and internal flat surfaces disposed between a pair of cross member longitudinal edges and a cross member tubular condition having opposed cross member external and internal curved surfaces disposed between said pair of cross member longitudinal edges, said cross member first end and a cross member second end each correspondingly secured to a pair of said four longerons, said collapsible structure interconverts between a substantially planate condition disposing each of said four longerons and said plurality of cross members in said flat condition and a deployed condition disposing each of said four longerons in said longeron tubular condition and in a substantially fixed relation generally defining a rectangular volume.
