REFLEKTIERENDER WAERMEISOLATIONSMANTEL AUS METALL

摘要

An axially extensible and contractable reflective thermal insulative structure is disclosed, comprised of two telescoping sections, each containing a plurality of reflective metal sheets, adjacent pairs of sheets are disposed such that telescoping motion is permitted while simultaneously proper spacing of the sheets is maintained. The insulation unit may be flat or curved. In a preferred embodiment a restraining means controls the telescoping motion while preventing unintentional disassembly of the unit.
