| titleOfInvention | Collapsible truss unit for use in combination with other like units for the constructions of frameworks |
| abstract | ABSTRACT OF THE DISCLOSURE A collapsible, or deployable, truss unit to be combined with a multiplicity of other similar units for the construction of, typically, medium to large size frameworks for use in outer space. Generally of boxlike shape when deployed, the truss unit comprises two opposite end truss assemblies of rectangular or quadrilateral shape, and an intermediate truss assembly of similar shape interposed therebetween and linked thereto via additional truss members. Two opposite ones of the four truss members of the intermediate truss assembly have each a movable hinge assembly mounted thereto for longitudinal displacement. Each movable hinge assembly has two diagonal truss members pivoted thereto each at one end, the other ends of the diagonal truss members being pivoted to the respective end truss assemblies. The truss unit can be readily deployed or collapsed into flat form by forcibly moving at least one of the hinge assemblies along the associated intermediate truss member as by as by a wire and pulley arrangement driven by a reversible drive motor. |
