COMBINED RESONATOR HAVING IMPROVED ISOCHRONISM Russian patent published in 2019 - IPC G04B17/06 G04B15/02 

FIELD: watches and other time measuring instruments.

SUBSTANCE: claimed group of inventions relates to clock-making assemblies, as well as clock mechanisms and clocks comprising such assemblies. Clock-making assembly (10) comprises a combined resonator having at least two degrees of freedom and comprising first oscillator (O1) which has a reduced amplitude in first direction (Y), relative to which second oscillator (O2) oscillates, which second oscillator has a reduced amplitude in second direction (X) perpendicular to said first direction (Y), said second oscillator (O2) comprising second weight (M2) that supports a slide, said clock-making assembly (10) comprising mobile (3) that is arranged so as to apply torque to said resonator and comprising groove (1) in which said slide slides with minimum clearance, wherein said slide is arranged so as to at least follow the curvature of said groove (1) where it has one, or create rubbing friction in said groove (1), or repel internal lateral surfaces (11, 12) of said groove (1) by means of magnetised or electrified surfaces of said slide.

EFFECT: improved isochronism of the combined resonator.
