Definitions

  • the tourbillon mechanisms for timepieces were initially designed and made to stabilize the balance of the pendulum by means of the effects of gravitation on the pendulum balance.
  • the balancers are well balanced and especially in wristwatches the most important variations of market are due to variations in amplitude of the balance between the horizontal (or flat) and vertical (or hanging) positions of it .
  • the amplitude of the pendulum oscillations depends on the friction of its axis in its pivots, friction whose value varies according to the positions of the axis of the balance in space and in particular between its vertical position and its horizontal position.
  • the present invention proposes a timepiece comprising a tourbillon which distinguished by the fact that it comprises a single cage carrying the balance and rotating in one direction only, and in that the axis of rotation of the balance forms a wide angle (that is to say an angle of at least 45 °) with the axis of rotation of the cage, and so does the average steps in different positions hanging flat.
  • the invention relates to a timepiece comprising a movement incorporating a tourbillon mechanism according to claim 1.
  • the invention has significant advantages when this timepiece is a wristwatch because it takes different positions when it is worn on the wrist.
  • the invention also relates to a vortex mechanism according to claim 10.
  • the axis of rotation of the tourbillon cage forms an angle of 45 ° with the axis of the winding stem of the timepiece.
  • the axis of the balance forms a wide angle of at least 45 ° with the axis of rotation of the cage.
  • This angle which remains constant during the operation of the mechanism, is preferably equal to 90 ° (the two axes being perpendicular) or substantially close to 90 °. Thanks to this important angle between the axis of the balance and the axis of rotation of the cage, a multidirectional movement of the balance and pivots capable of compensating for the phenomenon of the above-mentioned hangman is obtained by using a single rotating cage for the whirlwind.
  • the axis of rotation of the tourbillon cage forms any angle, that is to say ranging from 0 ° to 90 °, thus including the values of 0 ° and 90 ° with the plane of movement of the timepiece. in which it is mounted, but this angle is preferably zero or straight, either parallel or perpendicular to this plane of movement. This angle remains constant during the operation of the mechanism.
  • the vortex mechanism of the present invention has only one cage.
  • the single figure of the accompanying drawing schematically illustrates a partial section of a timepiece comprising a tourbillon arranged according to the present invention.
  • the timepiece according to the invention comprises a lower plate 2 serving as support for a bridge 1 on one side and for a dial 3 on the other side.
  • the plate 2 comprises two legs a, b extending perpendicular to the bridge 1 and the plate 2, the end of the leg 2a bears on the upper face of the bridge 1.
  • the end of the leg 2a has a bore 4 receiving the hub 5 of a fixed wheel 6 having in section the shape of a bell, fixed to the bridge 2 with the aid of at least one screw 7.
  • the toothing 8 of this fixed wheel 6 is located on the edge of the bell and extends in a plane perpendicular to the dial 3 and the bridge 1.
  • the hub 5 of this fixed wheel 6 is itself provided with a bore 9 in which is housed a first bearing 10 formed of a pierced stone.
  • the second leg 2b of the plate 2 has at its end a bore 11 in which is housed a second bearing 12 also formed by a pierced stone.
  • the holes of the stones forming the first and second bearings 10,12 are aligned and located on an axis XX parallel to the dial 3, to the plate 1 and thus to the plane of movement of the timepiece.
  • This axis XX defines the axis around which the tourbillon cage rotates and in this embodiment the angle it forms with the plane of movement is substantially equal to zero.
  • the axis of rotation XX of the cage is therefore in a plane parallel to the plate 2 and / or the dial 1 if the movement comprises a dial, which is not necessary in all embodiments.
  • the angle formed by the axis of rotation X-X of the cage is therefore zero with respect to the plane of movement in this embodiment.
  • this axis XX of rotation of the tourbillon cage may form any angle with the plane of the clockwork movement in which it is mounted, but this angle remains constant during operation of the mechanism.
  • this angle between the axis xx of the cage and the plane of movement may be substantially equal to 90 °.
  • the vortex comprises a cradle 13 provided with two pins 13a, 13b located in the extension of one another and whose ends are pivoted in the bearings 10,12 respectively.
  • the middle part of this cradle carries the lower bearing 14 of the balance spring 15,16.
  • the upper bearing 17 of the balance spring 15, 16 is carried by an intermediate vortex bridge 18 fixed on the cradle 13.
  • the anchor 19 and the escapement 20, 21 are pivoted between the intermediate vortex bridge 18 and an upper vortex deck 22 fixed on the cradle 13 of the tourbillon.
  • the tourbillon cage is formed of the cradle 13 and the intermediate tourbillon 18 and vortex upper bridges 22.
  • the escapement 20,21 is formed by an escape wheel 20 cooperating with the pallets of the anchor 19 and by an escape pinion 21 in engagement with the toothing 8 of the fixed wheel 6.
  • the axis of the sprung balance 15, 16 is perpendicular to the axis XX of rotation of the tourbillon cage, but in variants this axis of the sprung balance 15, 16 could form a different angle, but all similarly large or important, that is to say that this angle can have a value of 45 ° to 90 ° with this axis XX of rotation of the tourbillon cage according to the invention.
  • the angle formed by the axis of the sprung balance, both with respect to the axis of rotation XX of the tourbillon cage and with respect to the plane of the clockwork movement in which the mechanism is mounted remains constant during the operation of the mechanism.
  • the trunnion 13b of the cradle 13 carries a driving pinion 23 engaged with the toothing 24 of a drive wheel 25 in the form of a bell integral with an axis 26 pivoted between the plate 2 and the bridge 1 of the movement of watchmaking.
  • This axis drive 26 carries a second wheel 27 engaged with the wheel of the timepiece.
  • the drive wheel 25 and the drive gear 23 preferably have conical teeth. It is the same for the fixed wheel 6 cooperating with the exhaust pinion 21.
  • This tourbillon mechanism can be incorporated in a timepiece with or without a dial, this dial when it exists is located in a plane parallel to the plane of movement of the timepiece.
