SINGLE LOCKED LOOP COUPLING STRUCTURE, SINGLE LOCKED LOOP COMPOSITE STRUCTURE, AND APPLIED PRODUCT THEREOF

摘要

A single locked loop coupling structure and a single locked loop composite structure capable of graphically analyzing a coupling structure for coupling three or more of members to each other from the view point of primary locking. The single locked loop coupling structure based on the primary locking capable of holding only the pre-set degree of freedom in one axial direction by connecting two members to each other in a loop shape among at least three members comprises three members adjacent to each other and three link means individually performing the primary locking with the adjacent members parallel with each side of a triangle individually connected to two adjacent members and set geographically. The structure may have four link means individually performing the primary locking with the adjacent members parallel with each side of one bent square having no vertex in a same plane among at least four members.
