Title:
EXPANDABLE REFLECTOR AND EXPANSION STRUCTURE FOR EXPANDABLE REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2019/211964
Kind Code:
A1
Abstract:
An expandable reflector (100) is provided with: a support structure section (12) for forming a concave support surface in an expanded state; and a reflector section that is supported on the support surface and that forms a reflector surface. The support structure section (12) includes: a plurality of main support bodies (20) that are elongated along radiation directions from a reference axis (11) at the center; and a sub-support body (30) that is constructed between neighboring main support bodies (20). At least one of the plurality of main support bodies (20) is pivotally supported on the reference axis (11), and the angle relative to a neighboring main support body (20) can be increased and decreased about the reference axis 11 serving as an axial center. As a result of the angle between the main support body (20) pivotally supported by the reference axis (11) and the neighboring main support body (20) being increased, the sub-support body (30) expands in a circumferential direction so as to establish a lattice structure for defining a plurality of facets (37). In an expanded state, the support surface is formed by the plurality of main support bodies (20) and the sub-support body (30).
