WINDING DEVICE, IN PARTICULAR, FOR CLOCK FUSEE, EQUIPPED WITH MEANS FOR DISCONNECTION Russian patent published in 2024 - IPC G04B1/00 

FIELD: clocks and other time meters.

SUBSTANCE: invention relates to a winding device, in particular for a clock fusee, equipped with means for disconnection. Essence: winding device (1), in particular for fusee (2), is equipped with spring, comprises ratchet wheel (3) installed on rotary shaft (5) for winding, wherein rotary shaft (5) for winding, for example, is shaft for winding of fusee (2), rotation of which drives fusee (2), and gear mechanism (4) of winding device engaged with ratchet wheel (3), wherein rotation of gear mechanism (4) for winding causes rotation of ratchet wheel (3) and rotary shaft (5) for winding by applying torque to ratchet wheel (3), wherein winding device (1) is equipped with means (10) for disconnection of ratchet wheel (3) and rotary shaft (5) for winding, wherein means (10) for disconnection are located on ratchet wheel (3) and on rotary shaft (5) for winding and are made with possibility of disconnection of ratchet wheel (3) and rotary shaft (5) for winding, when torque applied to ratchet wheel (3), in fact, exceeds threshold value, in particular, when fusee (2) is fully wound. Invention also relates to a clock mechanism comprising such winding device (1).

EFFECT: increased reliability due to elimination of fusee damage, such as coating scoring, accumulation of sediment and wear of walls under pressure of completely wound plate of spring, as well as due to exclusion of the use of standard torsion limiting devices based on friction of the spring inside the fusee.
