  • Patent number: 10234823
    Abstract: A timepiece pallet fork for a mechanical oscillator including an arbor allowing the timepiece pallet fork to oscillate about a pivot axis, first and second pallets configured to alternatively engage with an escapement wheel when the timepiece pallet fork oscillates, the first pallet being displaceable with respect to the arbor by absorption of energy, the first pallet being displaceable from a first upstream waiting position to a first downstream stopping end position which is offset compared to the first upstream waiting position, and a first arm having an intermediate section including an elastic bend, one end of the arm being fixed with respect to the arbor to form a first fixed end, the intermediate section of the first arm being located between the first fixed end and the first pallet and returning the first pallet towards the first upstream waiting position by the intermediate section being elastically deformable from a first configuration into a second configuration.

  • Patent number: 9292004
    Abstract: A gong for a striking-work device of a timepiece. The gong includes a spring blade forming a main body of the gong and is adapted to act as a vibrating member so as to produce a sound following an actuation. The spring blade includes at least one opening formed in its main body. The invention also includes a timepiece, such as a mechanical watch, comprising such a gong.

  • Publication number: 20150323903
    Abstract: A striking watch including a watch case delimiting an internal chamber, as well as the insert partition defining an acoustic sound emission membrane, the insert partition divides the internal chamber into an acoustic cavity and a tight housing which receives a timepiece movement and a gong provided to vibrate after having received an impact from a striking mechanism associated with the timepiece movement, and the acoustic cavity is delimited at least by the insert partition and by a back cover, and the insert partition bears the gong.
