ADJUSTABLE TORSION HINGE Russian patent published in 2014 - IPC E05F1/12 

FIELD: machine building.

SUBSTANCE: adjustable torsion hinge comprises a hinge unit, a torque generation unit and a torque adjustment unit; the first and the second plates of the hinge unit are conjugated with a pivot axis and form a pivot joint with the first and the second clutches; the torque generation unit comprises a torsion spring to provide for a recuperation return; the torque adjustment unit comprises a torque adjustment element; the first clutch includes the first jaw inside it and the torque adjustment element includes the second jaw conjugated with the first jaw thus making the torque adjustment element regulate the torque of the torsion spring, due to the above the conversion between the first and the second clutches allows for the usage of the supporting hinge in both directions.
