US Patent 7714260 Stackable heliostat frame structure

A heliostat includes a pedestal, a transmission system, a heliostat frame assembly, and a mirror assembly. The heliostat frame assembly generally includes a first heliostat frame set and a second heliostat frame set mounted to the transmission system which is mounted upon the pedestal. Each heliostat frame set includes a stackable heliostat inner frame assembly and a stackable heliostat outer frame assembly. Each stackable heliostat inner frame assembly is identical and each stackable heliostat outer frame assembly is identical such that a multiple of heliostat inner frames and a multiple of heliostat outer frames are readily stackable in a nested arrangement for storage and transport.
