  • 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: 9811053
    Abstract: A reverser for a timepiece comprises a first input wheel which carries a first satellite pinion. An output mobile assembly comprises a first ratchet with which the first satellite pinion forms a click locking in rotation the output mobile assembly with respect to the first input wheel only in a first direction of rotation. A second input wheel has the same axis of rotation as the first input wheel and the output mobile assembly. A second satellite pinion and a second ratchet form together a click locking in rotation the output mobile assembly with respect to the second input wheel only in the first direction of rotation.

  • Patent number: 9158283
    Abstract: A reverser for a timepiece including a first input moving part having a first receiving toothing and integral with a first transmission toothing, a second input moving part having a second receiving toothing and integral with a second transmission toothing, a first satellite cooperating with the first transmission toothing configured to rotate in a single direction, a second satellite cooperating with the second transmission toothing configured to rotate in a single direction, the satellite being freely rotatable relative to the first satellite, a satellite carrier carrying the second satellite and an output moving part integral with the satellite carrier in which the first satellite is carried by the satellite carrier.
