  • Patent number: 11934150
    Abstract: A horological movement includes a resonator and an escapement wheel with flexible teeth, and an anchor formed of two mechanical pallets capable of abutting, when the anchor switches between its two rest positions, with any one of the flexible teeth depending on the angular position of the escapement wheel. Each flexible tooth is arranged to bend by undergoing an elastic deformation under a radial force that can be exerted by one of the two mechanical pallets abutting against this flexible tooth while the escapement wheel has an unfavourable angular position and the resonator is braked by the anchor. Each tooth has an elastic capacity to elastically absorb, in a radial direction, most of a maximum mechanical energy that the mechanical resonator may have during normal operation of the horological movement, to avoid breakage or deterioration of the escapement.

  • Patent number: 11927917
    Abstract: The horological movement includes a mechanical resonator and an escapement including an escapement wheel, which has a plurality of teeth, and an anchor formed by a stick and two arms having respectively two mechanical pallets likely to come into contact, when the anchor is subject to an alternative movement, with any of the teeth according to the angular position of the escapement wheel. To avoid damage to the escapement during rocking of the anchor while the escapement wheel is positioned in an unfavourable angular position, the anchor is arranged, during the rocking of this anchor, to be able to bend being subjected to an elastic deformation. The anchor has an elastic capacity between each of the two mechanical pallets and a fork of the anchor, enabling it to absorb elastically, during the elastic deformation, a maximum mechanical energy that the mechanical resonator can have during the normal functioning of the horological movement.

  • Patent number: 11927921
    Abstract: The main element 2 is connected to the mechanism of the movement, having parts 4, 5, by an arbor about which it can turn. To this end, it comprises an attachment 6 for fixing to the movement, which is for example formed by a small ring arranged in the opening 9 of the ring of the main element 2. The attachment 6 is thus composed of the same material as the main element and is arranged in the same plane. By virtue of the attachment 6, the winding mass can make a circular movement about the arbor, when it oscillates.

  • Patent number: 11892807
    Abstract: A method for measuring the medium frequency of a digital signal derived from a reference periodic signal generated by an electronic oscillator (quartz oscillator) forming a timepiece (2) which includes an analogue time display device and a continuous rotation electromechanical transducer (generator or continuous rotation motor) which is kinematically linked to this display device and wherein the medium rotational speed is regulated by a regulation device. The medium frequency of the digital signal is determined by a measurement device (70) without galvanic contact with the movement of the timepiece. The measurement method makes it possible to determine the rate of the timepiece and the precision of the electronic oscillator based on regulation impulses detected by a magnetic sensor (72) and over a measurement period limited to the duration of an inhibition cycle of periods of the reference periodic signal.
