SCISSORS-TYPE RETRACTABLE STRUCTURE

摘要

Provided is a scissors-type retractable structure 1 which is extendable in an extension direction. The retractable structure 1 includes at least one scissors frame 4 including a plurality of frame elements 3 each comprised of two frame members 2 pin-connected to each other at central portions of the frame members 2, and formed by pin-connecting the plurality of frame elements 3 to each other at end portions of the frame members 2. When the scissors frame 4 is in an extended state, part of the frame members 2 forming the frame elements 3 and positioned on a near side are linearly coupled to each other, and the other part of the frame members 2 forming the frame elements 3 and positioned on a far side are linearly coupled to each other, thereby causing upper surfaces of the frame members 2 to form a continuous flat surface.
