HOROLOGICAL REGULATING MEMBER HAVING A BALANCE SPRING AND PROVIDED WITH TEMPERATURE-COMPENSATION MEANS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027966 titled 'HOROLOGICAL REGULATING MEMBER HAVING A BALANCE SPRING AND PROVIDED WITH TEMPERATURE-COMPENSATION MEANS

Simplified Explanation

The patent application describes a regulating member for a horological movement, such as a watch movement, that includes an oscillating weight (e.g., a balance) and a balance spring wound in multiple turns. The balance spring has a predefined rigidity that allows the oscillating weight to undergo a rotary oscillatory motion. The regulating member includes a temperature-compensating resilient device that adjusts its stiffness based on the temperature to compensate for the temperature's effect on the regulating member. The resilient device includes a resilient element connecting the outer end of the balance spring to a stationary support, as well as preloading means for applying a variable force or torque to the resilient element based on the temperature.

  • The patent application describes a regulating member for a horological movement with an oscillating weight and a balance spring wound in multiple turns.
  • The balance spring has a predefined rigidity that allows the oscillating weight to undergo a rotary oscillatory motion.
  • The regulating member includes a temperature-compensating resilient device that adjusts its stiffness based on the temperature.
  • The resilient device includes a resilient element connecting the outer end of the balance spring to a stationary support.
  • Preloading means are used to apply a variable force or torque to the resilient element based on the temperature.

Potential applications of this technology:

  • Watch movements: The temperature-compensating resilient device can be used in watch movements to ensure accurate timekeeping regardless of temperature changes.
  • Precision instruments: The technology can be applied in other precision instruments that require precise oscillatory motion, such as chronometers or scientific instruments.

Problems solved by this technology:

  • Temperature effects: The temperature-compensating resilient device addresses the issue of temperature affecting the performance of the regulating member in horological movements. It helps maintain accurate timekeeping regardless of temperature changes.

Benefits of this technology:

  • Improved accuracy: By compensating for temperature effects, the technology ensures more accurate timekeeping in horological movements.
  • Reliability: The temperature-compensating resilient device enhances the reliability of the regulating member by minimizing the impact of temperature changes.
  • Versatility: The technology can be applied to various horological movements and precision instruments, providing a versatile solution for temperature compensation.
