摘要

The hinge device comprises one or more hinge pieces (1), and a blocking device, which protects one or multiple another hinge pieces (2) against front and return oscillations, and rotates around a common axis (5). The hinge pieces are engaged together by two threadings (11,12). The thread pitch of the former threading averages 1.05 to 1.4 times of the thread pitch of the latter threading.
