Flexible line, e.g. for gas, with central adjustment of the bending radius has chain with elements of even and odd order coupled together in shape-locking manner so as to undergo approximately same pivot angle in each movement direction

摘要

The flexible line consists of a hose (2) and a chain with elements (3,4) providing space for the hose and pivotable about axes transverse to the longitudinal axis of the respective elements. The elements of even order and the elements of odd order are coupled together in a shape-locking manner so as to undergo approximately the same pivot angle in each movement direction.
