Abstract:
1. A mechanical support ring structure being convertible from a folded state into a deployed state, comprising: a ring-shaped pantograph having a plurality of circumferentially arranged pantograph sections which are deployable for converting the mechanical support ring structure from the folded state into the deployed state, and a plurality of circumferentially arranged support rods, each pantograph section being arranged between a respective pair of support rods, wherein each pantograph section comprises two or more pairs of crosswise intersecting pantograph rods including a first pair of pantograph rods which intersect crosswise with each other at a respective crossing position, and wherein, for each pantograph section, each pantograph rod of the first pair is pivotably attached with a left end thereof to a left support rod at a left attachment position and is pivotably attached with a right end thereof to a right support rod at a right attachment position, wherein the pantograph rods of the first pair of crosswise intersecting pantograph rods are respectively configured such that a ratio between a first distance, which is the distance between the crossing position and the left attachment position, and a second distance, which is the distance between the crossing position and the right attachment position, is alterable when converting the mechanical support ring structure from the folded state into the deployed state.
