ENGAGEMENT CHAIN UNIT

Document Type and Number:

WIPO Patent Application WO/2012/144281

Kind Code:

A1

Abstract:

Provided is an engagement chain unit configured so that chains reliably and firmly engage with each other and that the buckling and twisting of a rigidified chain portion are avoided. An engagement chain unit (100) is configured in such a manner that the outer edges of a plate overlap region (P) are defined by contact portion surfaces (111aa, 111aa) and flat, buckling restricting end surfaces (112b, 112b), and that the plate overlap region (P) is constructed from the outlines of two plate overlap portions (Pa, Pa) which are point-symmetric about the point (C) of intersection between hook-shaped engagement end surfaces (111a, 111a) and the buckling restricting end surfaces (112b, 112b).
