Patent ID: 8683755

Claim:
An elastic deployable structure comprising: a. at least one elastic roll out boom, wherein said at least one elastic roll out boom comprises a thin-wall tubular, elongated structure, having a first end, a second end opposite said first end, and a longitudinal axis, b. a boom mandrel, said boom mandrel being a substantially cylindrical structure, said cylindrical structure also having a longitudinal axis upon which said mandrel is able to rotate about said longitudinal axis of said boom mandrel, c. a yoke support structure, said yoke support structure providing a fixed base for deployment of said at least one elastic roll out boom, d. wherein said at least one elastic roll out boom is attached at said first end to said boom mandrel, and at said second end to said yoke support structure wherein said longitudinal axis of said roll out boom is perpendicular to said longitudinal axis of said boom mandrel, wherein said elastic roll out boom cross section can be flattened and rolled tightly around said boom mandrel to form a stowed roll, said stowed roll having a diameter, wherein said stowed roll confines elastic strain energy for powering deployment, and e. a deployment control device, wherein said deployment control device prevents expansion of said diameter of said stowed roll and insuring unidirectional deployment of said at least one elastic roll out boom wherein said deployment control device comprises (i) stabilizer arms and boom control rollers, wherein said stabilizer arms connect said boom control rollers to said longitudinal axis of said boom mandrel, (ii) a frictionless tensioned containment strap, and a strap cross bar, wherein said frictionless tensioned containment strap surrounds said stowed roll, wherein said frictionless tensioned containment strap has a first end and a second end, said first end being connected to said stabilizer bar, said second end being connected to said strap cross bar, (iii) wherein said frictionless tensioned containment strap controls said stowed roll diameter during deployment such that unidirectional boom deployment is effected.
