Abstract
The present invention concerns a mechanical oscillator, comprising an oscillating system comprising a balance (1) and its return spring (3). This oscillator also comprises two elastic strips (9, 10) fixed by one end and acting in opposition intermittently by their other end on a connecting organ (8) secured to the oscillating system.
Claims14
A mechanical oscillator comprising an oscillating system, mounted on a frame and comprising a balance and its return spring, said oscillator further comprising a frequency correction device, wherein said frequency correction device comprises at least first and second elements fixed to said frame and said oscillating system, respectively, the first of these elements comprising at least one flexible elastic strip fixed by one of its ends and the second being a connecting organ weighing, during part of each oscillation, against the free end of said strip.
A mechanical oscillator, comprising:
- a frame;
- an oscillating system, mounted on the frame and comprising a balance and a return spring;
- and,
- a frequency correction device, said frequency correction device comprising a first element fixed to said frame and a second element fixed to said oscillating system,
- the first element comprised of a pair of elastic strips having first ends fixed to said frame, the elastic strips each having a free end,
- the second element being a connecting organ connected to the balance,
- the free ends of each of the pair of elastic strips pressing, in opposition, on the connecting organ during a part of each oscillation, the elastic strips functioning as an additional spring on the balance.
