FOLDING MULTIPLE CRANK-AND-ROCKER MECHANISM Russian patent published in 2025 - IPC F16H21/00 F16H21/26 F16H21/54 B01F31/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Folding multiple crank-and-rocker mechanism is made in the form of a hinged four-link linkage consisting of four hinged-connected lever links forming, after their assembly into a closed kinematic chain, a post, a driving crank, a connecting rod and a driven rocker arm. Two lever links of this chain are made of the same length and are connected directly to each other through a hinge or kinematically interconnected by means of another lever link. Two other lever links are of different length. Driven rocker arm is additionally connected to the post by means of an elastic torsion element made in the form of a torsion shaft or a helical spring coaxial to the driven rocker arm.

EFFECT: increased amplitude of angular oscillations of driven rocker with working member and expansion of working space.
