Definitions

  • the present invention relates to a watch movement with a mechanism for moving an oscillator intended to make the latter less sensitive to the force of gravity.
  • the object of the invention is to propose a watch movement with low sensitivity with respect to gravity whatever its position in order to reduce its rate deviation without hiding the oscillator in cages.
  • the invention relates to a watch movement comprising a plate formed of a horizontal main surface projecting vertically and on which is mounted at least one oscillator comprising a resonator able to oscillate around a first axis of rotation to serve time base to the horological movement, and an escapement device selectively applying to the resonator a force of the horological movement in order to maintain and count the oscillations of the resonator, characterized in that the horological movement comprises a mechanism for moving the oscillator with respect to the plate configured to drive an oscillator support in revolution with respect to a second horizontal axis, the oscillator support of the displacement mechanism being oriented along a third axis oblique with respect to the second horizontal axis of revolution so as to that the displacement of the third axis with respect to the second horizontal axis of revolution forms a conical surface of revolution making it possible to change the orientation of the oscillator with respect to the plate with each oscillation of the resonator in order
  • the oscillator moves according to a movement capable of making it less sensitive to the consequences of the force of gravity while being guided in a simple manner at all times.
  • the oscillator by its movement makes it possible to reduce the rate deviation of the watch movement.
  • the invention may also include one or more of the following optional features, taken alone or in combination.
  • the mechanism for moving the oscillator may comprise a force transmission shaft of the watch movement centered on the second horizontal axis of revolution and on the external surface of which the oscillator support is fixed in order to facilitate the movement of revolution of the support of 'oscillator.
  • the transmission shaft is intended to receive the mechanical force of the watch movement such as, for example, that of a barrel in order to communicate it to the oscillator support.
  • the mechanism for moving the oscillator may comprise a conical transmission fixed with respect to the plate and coupled to the escapement device so as to move the oscillator support by revolution with respect to the second horizontal axis at each resonator oscillation.
  • the oscillator support receiving force from the watch movement via the transmission shaft tends to be driven in revolution along the second horizontal axis.
  • the escapement device engages with the bevel gear fixed relative to the plate. It is therefore understood that the force of the watch movement is supplied to the oscillator at each passage of the tooth of the bevel gear and causes the movement by revolution of the oscillator support along the second horizontal axis. This transfer of force can be similar to that of a classic tourbillon mechanism.
  • the mechanism for moving the oscillator may comprise a conical transmission force transmission of the watch movement which is movable relative to the plate, coupled to the escapement device and mounted coaxially to the transmission shaft of force in order, by relative displacement between the bevel gear and the transmission shaft, to move the oscillator support by revolution with respect to the second horizontal axis at each oscillation of the resonator.
  • the oscillator support receiving force from the watch movement via the transmission shaft tends to be driven in revolution along the second horizontal axis.
  • the escapement device engages with the conical force transmission transmission of the watch movement. It is therefore understood that two distinct forces are brought to the movement mechanism of the oscillator.
  • the watch movement is arranged so that the forces supplied impose a relative displacement between the bevel gear and the transmission shaft so that a force from the watch movement is brought to the oscillator at each tooth passage of the bevel gear and causes the oscillator support to move by revolution along the second horizontal axis.
  • These transfers of force can be similar to that of a conventional carousel mechanism.
  • the oscillator displacement mechanism may comprise a counterweight element mounted opposite the oscillator support with respect to the second horizontal axis in order to compensate for the unbalance of the revolution displacement of the oscillator support.
  • the angle between the third axis and the second horizontal axis can be greater than zero degrees and less than ninety degrees.
  • the angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70° , 75°, 80° or 85°.
  • the higher the angle the greater the outer envelope of displacement required. It is therefore preferred to remain below thirty degrees in order to retain a certain compactness of the watch movement.
  • the watch movement may comprise several oscillator displacement mechanisms, each mechanism displacing an oscillator.
  • the second horizontal axes of two oscillator supports may coincide, the two oscillator supports being able to be angularly offset by one hundred and eighty degrees with respect to the second horizontal axes making it possible to balance the center of gravity of the displaced masses.
  • the resonator may be of the balance-spring type and the escapement device may be of the Swiss lever type.
  • the invention relates to a timepiece characterized in that it comprises a timepiece movement as presented above.
  • orientations are the orientations of the figures.
  • the terms “upper”, “lower”, “left”, “right”, “above”, “below”, “forward” and “backward” generally mean with respect to the direction of representation of the figures.
  • axes (A1, A2, etc.) are arbitrarily declared as a first axis, a second axis, etc. It is a simple nomenclature for differentiating and naming non-identical geometric elements. This nomenclature does not imply a priority of one axis relative to another and it is easy to interchange such denominations without departing from the scope of the present description. This nomenclature also does not imply an order, that is to say that a third axis could be used without a first axis and/or a second axis being necessary for the implementation of the invention.
  • timepiece 2 is meant all types of instruments for measuring or counting time such as clocks, clocks, watches, etc.
  • the watch movement 3 comprises at least one mechanism 1 for moving the oscillator 5 intended to impose a movement with horizontal and vertical components with respect to the plate 4. More precisely, the movement mechanism 1 is configured to drive a support 12 of oscillator 5 in revolution with respect to a second horizontal axis A2 (longitudinal) which is oriented along a third axis A3 oblique with respect to the second horizontal axis A2 of revolution (longitudinal).
