TIMEPIECE REGULATING MEMBER WITH A BALANCE SPRING PROVIDED WITH MEANS FOR GRAVITY COMPENSATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027965 titled 'TIMEPIECE REGULATING MEMBER WITH A BALANCE SPRING PROVIDED WITH MEANS FOR GRAVITY COMPENSATION

Simplified Explanation

The abstract describes a regulating member for a horological movement, specifically for a balance and balance spring. The balance spring is a flexible strip coiled on itself, allowing the balance to perform a rotary oscillatory movement. The regulating member includes a resilient device that compensates for the effect of gravity on the regulating member by adapting its stiffness according to gravity. This resilient device consists of a resilient element connecting the outer end of the balance spring to a non-movable support, as well as prestressing means for applying a variable force or torque on the resilient element based on the direction of gravity.

  • The invention is a regulating member for a horological movement.
  • It includes a balance and a balance spring made of a flexible strip coiled on itself.
  • The strip has a predefined rigidity to enable the balance to perform a rotary oscillatory movement.
  • The regulating member compensates for the effect of gravity on the balance by using a resilient device.
  • The resilient device includes a resilient element connecting the outer end of the balance spring to a non-movable support.
  • Prestressing means apply a variable force or torque on the resilient element based on the direction of gravity.

Potential applications of this technology:

  • Watchmaking industry: The regulating member can be used in mechanical watches to improve accuracy and precision by compensating for the effect of gravity on the balance.
  • Chronometers: The technology can be applied in high-precision timekeeping devices to ensure accurate timekeeping even in different orientations or positions.

Problems solved by this technology:

  • Gravity effect: The technology solves the problem of gravity affecting the accuracy of horological movements by compensating for its effect on the regulating member.
  • Positional error: By adapting the stiffness of the resilient device according to gravity, the technology helps reduce positional errors in timekeeping devices.

Benefits of this technology:

  • Improved accuracy: By compensating for the effect of gravity, the technology improves the accuracy of horological movements.
  • Reduced positional errors: The technology helps minimize the impact of different orientations or positions on the timekeeping accuracy.
  • Enhanced reliability: By addressing the influence of gravity, the technology enhances the reliability and performance of timekeeping devices.
