MULTI-CIRCUIT HINGE MECHANISM Russian patent published in 2021 - IPC B25J17/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in manipulators of a parallel structure, in the field of construction based on movable frames and in radar devices with variable-shaped antennas. The multi-circuit hinge mechanism contains links articulated with each other, forming a closed kinematic chain. The mentioned kinematic chain is formed by double-hinged links, articulated with each other to form hinged parallelograms installed one inside the other. The tops of the parallelograms are connected in pairs by double-hinged links and rotary kinematic pairs with parallel axes of their angular rotation.

EFFECT: simplification of the design and reduction in the labor intensity of manufacturing and assembly of the multi-circuit hinge mechanism, as well as the expansion of the space of movement of the working body.
