Definitions

  • the present invention relates to a mechanical movement with a tourbillon and a mechanical clock equipped therewith.
  • Tourbillons for mechanical watches and movements are well known.
  • the escape wheel, the anchor and the so-called balance of the movement are arranged on a bogie, which is coupled to the shaft of the second wheel, and thus the second drive, or firmly connected.
  • the balance or balance axis typically coincides with an imaginary axle extension of the second drive.
  • a gearwheel connected to the escape wheel meshes with a stationary gear wheel arranged coaxially with the balance axis, so that the tourbillon, and therefore its frame, undergoes a complete revolution per minute.
  • balance rest which can be activated for example by pulling out a crown and deactivated by pushing the crown wheel back.
  • a rest stop for a tourbillon is from the EP 2 793 087 A1 known. This has a with the balance engageable and axially to the balance axis movable brake element. To balance the clock with a time standard, it is thus possible to stop the balance and thus the tourbillon mechanism as desired.
  • the present invention is an object of the invention to provide an improved rest stop for a tourbillon of a mechanical watch.
  • a zero position of the tourbillon for comfortable timing can be realized. This is to improve the operability and the time setting of the clock and also give the clock an increased range of functions.
  • a clockwork of a mechanical watch with a tourbillon unit is provided.
  • the movement has a board on which all movable components of the movement are arranged.
  • the movement, in particular its tourbillon unit further has a frame connected to a second drive, rotatably mounted on the board frame and mounted on the frame balance.
  • a second drive In addition to the balance, an escape wheel in operative connection with the balance is also mounted on the frame.
  • the escape wheel is typically via an armature in operative connection with the balance.
  • the balance, the anchor and the escape wheel form the inhibition of the mechanical movement.
  • the second drive is typically coupled to an energy storage device, such as a barrel, which ultimately drives the movement.
  • the movement is further provided with a balance engageable with the balance rest device.
  • the balance stop device By means of the balance stop device, the balance for stopping the movement relative to the board or relative to the frame at least temporarily fixed.
  • the movement is provided with a zeroing device, which allows to adjust the angular orientation of the frame in a predetermined position, which preferably corresponds to the zero position of a mounted on the frame second hand.
  • the zeroing device is optionally rotatably engageable with the frame or with the board.
  • the zeroing device is typically in the normal operation of the clock with the circuit board rotatably engaged.
  • the zeroing device is fixed relative to or on the board, while the frame together with the entire tourbillon unit is subjected to a rotational movement relative to the board.
  • the zeroing device is also detachable from the circuit board or rotatably decoupled, so that it can be rotated relative to the board. In this case, it is typically rotatably engaged with the frame.
  • the zeroing device is thus always either with the frame rotatably engaged or rotatably engaged with the board or the zeroing device is even with both the frame and the circuit board rotatably engaged.
  • rotatably engageable zeroing device By selectively with the frame or with the board rotatably engageable zeroing device can be achieved to decouple the frame for adjusting the time at least temporarily from the energy storage device of the movement.
  • an alternate fixation or rotationally fixed connection of the zeroing device with the frame or with the board can be achieved that the zeroing device together with the frame to bring about a zero stop function also approximately under the action of the mechanical Energy storage of the movement, but decoupled from the minute or hourly drive of the movement in a defined zero position can be converted.
  • the optional engagement of the zeroing device with the frame or with the board can be done by successive and stepwise pulling out a crown, such as an elevator or Einstellkrone the clockwork.
  • a crown such as an elevator or Einstellkrone the clockwork.
  • the crown may be in three different axial positions, ie a first so-called rest position in which, for example, a barrel can be wound through the crown as usual, a second position in which the balance is stopped, eg according to the solution of EP2793087 , and a third further drawn axial position in which the zeroing device is no longer engaged with the board, but now with the frame in engagement.
  • the minute hand position can be provided by turning the crown in this position.
  • the zeroing device in a basic configuration, is fixed against rotation on the circuit board.
  • the crown In the basic configuration, the crown is in a basic position, in which the movement is driven by the mechanical energy storage in motion. Due to the fixation on the board, the zeroing device acts as a kind of basis for the tourbillon unit. It may be provided in particular that the tourbillon unit or part thereof with the Zero setting are in operative connection. In the basic configuration with a zero-setting device fixed on the board, this only acts as a carrier for other mechanical components of the movement, for example for the tourbillon unit or for individual components thereof.
  • the zeroing device is non-rotatably coupled to the frame when the balance is stopped by means of the balance rest stop device.
  • the frame is freely rotatably mounted relative to the board. That is, only under the influence of the inhibition, the frame rotates relative to the board under the action of the spring drive outgoing mechanical drive energy.
  • the zeroing device and the balance stop device interact with one another in such a way that the zeroing device is rotationally fixedly coupled to the frame by activating the balance stop device. It is also conceivable that the zeroing device is already firmly connected to the balance stop device. A fixation of the frame relative to the board by means of the balance rest device thus inevitably leads to a rotationally fixed fixing of the frame relative to the zeroing device.
  • the zeroing device By a direct or indirect coupling of zeroing device and frame can be achieved that about the purpose of setting the clock, the zeroing device is rotatably connected to the frame. By means of the zeroing device can then be transferred from any position in which the frame was stopped, the frame fixed thereto in a defined zero position in which a second hand arranged on the frame pointer points to zero.
  • the balance stop device has a bogie and frictionally engaged with the balance in Engage engageable axially to a balance axis movable brake element.
  • a balance rest can be realized, which exerts no radial asymmetric forces on the balance or on the bogie of the tourbillon.
  • the balance can also be braked directly via the brake element, in particular stopped. By slowing down and stopping the balance will inevitably stop the rotation of the tourbillon, that is, the rotational movement of the bogie.
  • the balance-rest device acts exclusively on the balance in the axial direction makes the balance-rest stop device particularly suitable for achieving a rest stop in the case of a flying tourbillon.
  • a frictional braking of the balance also allows the balance to be stopped in any arbitrary orientation and position of the balance.
  • the zeroing device via the brake element rotatably coupled to the frame.
  • the zeroing device can, in particular, act directly or indirectly on the brake element arranged, for example, on the frame.
  • the zeroing device but at least individual components or parts thereof may or may be in particular in the power flow of the balance rest stop device.
  • the zeroing device by means of a fixing member rotationally fixed to the board can be fixed.
  • the zeroing device can optionally be fixed in a rotationally fixed manner to the printed circuit board or else detached therefrom, so that the zeroing device is rotatable with respect to the printed circuit board.
  • the fixing element can be transferred only in a rotationally fixed coupling of frame and zeroing device in a release position, in which the zeroing device is rotatable together with the frame relative to the board.
  • the frame is coupled to the zeroing device and the fixing element is transferred to the release position, typically an optionally damped rotational movement of the ensemble formed by frame and zeroing ensembles, wherein the bogie is operatively connected by the activated balance device with the energy storage device of the movement.
  • the second drive of the tourbillon is in this configuration still with the energy storage device of the movement, such as the barrel, in mechanical operative connection.
  • a pawl is further arranged to be movable on the board. This cooperates with a frame arranged on the locking cam to stop the frame in a neutral position.
  • the pawl for example, can be transferred radially inwardly into a locking position, in which they are so with the locking cam of the Gestells cooperates, which prevents rotation of the frame beyond the pawl or past the pawl.
  • the latching cam may, for example, protrude radially outward from the frame.
  • the pawl is, for example, in a radially inwardly engaged detent position and the zeroing device together with the frame subject of a rotary motion at a located in the release position fixing element, the locking cam of the frame comes into engagement with the pawl.
  • the pawl thus acts as an end stop for the locking cam and thus for the frame so that it comes to rest in the intended zero position for adjusting the movement.
  • the pawl is coupled to the fixing element.
  • the pawl is at least only in a detent position for stopping the frame when the fixing passes from the fixing position in the release position.
  • the pawl and the fixing are so far rigidly coupled together. If the ensemble of frame and zeroing device is released for rotational movement, the pawl engages radially inward to stop the free rotation of the ensemble at a fixed predetermined position.
  • detent cam and pawl thus determines the zero position of the frame and thus the arranged on the frame second hand of the tourbillon.
  • the zeroing device has a carrier wheel with a rim-like circulation tire.
  • the circulating tire is rotatably mounted on its outer circumference at least three arranged on the board bearing rollers.
  • the zeroing device has in particular a ring-like basic geometry.
  • the hub of the tourbillon unit typically extends through the remaining center of the nulling device.
  • the zeroing device on a ring-like epicyclic gear with an internal toothing, which meshes with a pinion of the escape wheel.
  • the planetary gear of the zeroing device which is also fixed relative to the board in the basic configuration or while the movement is running, meshes with the escape wheel.
  • the escapement wheel moves in particular due to the teeth of its pinion with the internal toothing along that internal toothing, when the tourbillon unit is subject to a prevailing during operation of the movement rotational movement.
  • the zeroing device acts in this respect as an extended board, on the internal toothing of which the escape wheel runs along with its pinion.
  • the zeroing device has a, relative to its axis of rotation, axially movable stop ring. This has on a radially outer edge on a run-on slope, which corresponds to a run-on slope of a movable arranged on the board stop pawl. Typically, two diametrically opposed stop pawls are provided. These can experience a radially inwardly directed movement in the direction of the stop ring with a pulling out of the crown.
  • stop ring undergoes an axial movement when the stop pawl or the pawls are moved radially inward.
  • a radial movement can thus be converted into an axial movement.
  • the at least one pawl of the zeroing device can be deflected radially inwards by an axial movement of the stop ring induced by means of the at least one stop pawl.
  • the at least one pawl at its radially inner end on a run-on slope, which is engageable with a run-on slope of a brake ring.
  • the brake ring is typically disposed axially adjacent the pawl and is also axially slidable relative to the zeroing device on a major axis of the tourbillon unit, for example, on the hub of the tourbillon unit. Since the at least one pawl and the brake ring engaging therewith have mutually corresponding run-on slopes, the typically radially inwardly directed pivoting or adjusting movement of the pawl can be transmitted into an axially directed displacement movement of the brake ring.
  • a brake pin is axially movably guided in a hub of the tourbillon unit or in the frame and for the deflection of the brake element and for stopping the balance by means of the brake ring axially is displaceable.
  • the brake pin is in particular against a restoring force, in particular against the action of a spring element axially displaceable to the brake ring.
  • the brake pin deflects the brake element, which is movable axially relative to the balance spring, in such a way that it frictionally engages with the balance and finally stops the balance.
  • At the zeroing device is typically not only one, but there are several, approximately three circumferentially equidistantly arranged pawls provided, which perform a synchronous, radially inwardly directed movement due to an axial movement of the adjacent thereto arranged stop ring. Accordingly, a possible uniform and symmetrical displacement force can be exerted on the brake ring, which ultimately leads to the axial propulsion of the brake pin.

  • the Kleinêtrad 7 meshes with a minute wheel 8, which is in engagement with a barrel 9, which in the present case acts as a mechanical energy storage device.
  • the tourbillon unit 10 also has an in Fig. 11 shown in cross-section hub 6, which is rotatably mounted on the board 2 and fixedly connected to a frame 11 of the tourbillon unit 10.
  • the frame 11 comprises a lower frame 11a with various radially aligned spokes 11d, via which the frame 11 is connected to the hub 6.
