Embodiment Construction

[0019] 1, 3, 6, 7, 8, 9 and 10, shown with the general reference numeral 1 in the equilibrium position, the anti-trip balance spring is usually wound by a reed 10 in a helical shape around itself to have an angular orientation ( angular) elastic and composed. The central end 11 of the reed 10 is fixed in known manner to a collet 20 driven on the balance arbor 21 , while its peripheral end 12 is supposed to be fixed to a balance cock, not shown. Balance spring 1 comprises, from one end to the other, a plurality of rotating turns 13, usually between 10 and 15, at a distance p between the turning turns in equilibrium.

[0020] According to the invention, the balance spring 1 further comprises a plurality of transverse portions 15, 15', 15"a, 15"b, 15"c integrally formed with the continuous ring 13 and arranged angularly in the balance spring 1 the rotational amplitudes from the equilibrium position to one of their end positions abut each other over a defined angle Ψ comprised be...

Abstract

The anti-tripping hairspring (1) has a blocking unit for blocking multiple turns (13), when rotation amplitude of the hairspring from balancing position to an extreme position attains determined angle. The unit has transversal segments (15) integrated to the turns, where the transversal segments are radial. The transversal segments are extended beyond two portions of a spiral (14), where the hairspring is made of silicon and metal. An independent claim is also included for a detect escapement of a timepiece comprising a tilting unit.

Description

technical field [0001] The invention relates to an anti-trip balance spring for a detent-type timepiece escapement without a stop element. Background technique [0002] The phenomenon of tripping is well known to those skilled in the art. Primarily concerns the detent escapement and, when this phenomenon occurs, greatly reduces the accuracy of timepieces incorporating the escapement. [0003] The detent escapement is mainly used in precision timepieces because it interferes less with the isochronism of the oscillator than the Swiss lever escapement. For a detailed description of this type of escapement, refer to chapter 6.7.1 of the reference book entitled "Théorie de l'horlogerie" (Theory of Horology). We will only cover here how the detent escapement is prone to tripping. [0004] In a detent escapement, the balance with sprung oscillator oscillates between two extreme positions, the "high" and "low" positions. Each oscillation consists of an "up" vibration and a "down...
