FIELD: machine building.
SUBSTANCE: invention relates to the machine building. Hinged crank mechanism comprises a closed kinematic chain including a post, a connecting rod and rotary lever links arranged between them. Closed kinematic chain is made in the form of multi-contour hinged parallelogram, in which each separate connecting rod is made in form of three-hinged link, for example in form of equilateral triangle of three-hinged con-rod, kinematically connected to the rack by means of two-hinged bell cranks of equal length and parallel installed in each direction in one direction during assembly of kinematic chain with formation in it connected to each other through three-hinged con-rod parallelogram closed circuits.
EFFECT: better performance is provided.
