Abstract (en)
[origin: RU2680411C1] FIELD: watches and other time measuring instruments.SUBSTANCE: claimed group of inventions relates to devices of control clockwork mechanisms and clocks comprising such mechanisms. Control clock mechanism (100) comprises movably mounted at least rotable relative to platinum (1) trigger wheel (51), to which torque is transmitted through a gear train, first oscillator (110) comprising first rigid structure (310) connected to platinum (1) by first flexible strip (210A) and second flexible strip (210B), intersecting with each other, second oscillator (120) comprising second rigid structure (320) connected to first rigid structure (310) third flexible strip (220A) and fourth flexible strip (220B) intersecting with each other, wherein second structure (320) including guide means (42), interacting with response guide means (52), included in trigger wheel (51), synchronizing first oscillator (110) and second oscillator (120) with the gear train.EFFECT: technical result is improved clock chronometric characteristics.27 cl, 5 dwg
