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.
  • any angular orientation of the tourbillon should also be realized. This is said to give an increased functionality, e.g. the position of the bogie at any time compared to the wheel train and thus the pointer movement retuned or adjusted.
  • the invention makes it possible for the first time to move an entire tourbillon independently of its escapement section in the movement controlled from the outside. This independent movement allows a tourbillon to be rotated more quickly to a moving point in any position. This possibility can be set to the second-precise setting of the time or for other functions, such as. Short-term measurements are used by means of the tourbillon.
  • the present movement is provided with a balance-engageable with the balance rest stop 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 equipped with a removable fixed wheel unit, which allows the angular orientation of the frame in any position adjust.
  • the disengageable Fixradä is selectively rotatably engageable with the frame or with the board; the deactivatable fixed wheel unit is typically in the normal operation of the clock with the circuit board rotatably engaged.
  • the disengageable fixed wheel unit 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 removable Fixradiser is detachable from the board or rotatable decoupled so that it can be rotated relative to the board.
  • it is typically rotatably engaged with the frame.
  • the disengageable Fixradiser is thus preferably always rotatably engaged either with the frame or with the circuit board rotatably engaged or even with two, the frame and the circuit board rotatably engaged.
  • the present movement is coupled with an adjustment mechanism, which is controlled, for example, by an elevator or Einstellkrone of the movement.
  • an elevator or Einstellkrone of the movement By successive and gradual pulling out of the crown can be optionally determined 3 different modes in which the winding crown each has a specific function, namely the elevator of the barrel, the pointer position, and causes the setting of the tourbillon.
  • the crown can be in three different axial positions
  • the first in which, for example, a barrel can be threaded through the crown as usual, is the so-called rest position; in the In the second position the balance is stopped, eg as per the solution of EP2793087 , and thus enables the pointer position; Finally, in the third extended axial position in which the disengageable Fixradiser is no longer with the board, but now with the frame engaged, at the same time the tourbillon is coupled from the wheels, so that the angular alignment is made possible by the rotation of the crown.
  • the tourbillon drive should be formed in two parts, with a first part is coupled to the drive, and the other part is adjustable thanks to a second frame with rotationally fixed teeth, so that the synchronization is not lost for minutes.
  • the existing control mechanism which determines the respective functions of the crown, a camshaft having 3 cams arranged on each other, which engage on three different schematics, and respectively the rest stop, the release of the holding lever for the removable Fixradiser and the Decoupling the second drive cause.
  • the rest stop is preferably in the second position of the crown, wherein both the liberation of the holding lever and the decoupling of the secondary drive occur simultaneously when moving the crown from the second position to the third position.
  • the disengageable Fixradillon a carrier wheel with a rim-like circulation on.
  • 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. In a final assembly configuration of the movement extends through the remaining ring center of the zeroing typically the hub of the tourbillon unit.
  • the deactivatable fixed wheel unit has an external toothing which engages with a control wheel controlled by the winding crown in the third pulled position of the winding crown.
  • the disengageable Fixradiser on a ring-like epicyclic gear with an internal toothing, which meshes with a pinion of the escape wheel.
  • the planetary wheel of the disengageable Fixradiser which is also fixed in the basic configuration or running clockwork relative to the board, 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 disengageable fixed wheel unit acts as an extended board, on whose internal teeth the escape wheel runs along with its pinion.
  • the disengageable Fixradiser a based on its axis of rotation, axially movable stop ring. This has at a radially outer edge on a run-on slope, which corresponds to a run-on slope of a movably arranged on the board balance stop lever.
  • two diametrically opposed balance stop levers 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 Due to the mutually corresponding and with respect to their slopes matched ramps of stop ring and balance stop lever, the stop ring undergoes an axial movement when the Rest stop lever is 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 means of an axial movement of the stop ring induced by means of the at least one balance stop lever. Due to the mutual engagement of the balance stop lever, stop ring and pawl of the deactivatable fixed wheel unit, it is possible to convert a pivoting movement acting radially from the outside onto the deactivatable fixed wheel unit into a pivot movement of a pawl provided radially inwardly on the switchable fixed wheel unit.
  • 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 deactivatable fixed wheel assembly on a main axis of the tourbillon unit, for example, on the hub of the tourbillon unit.
  • a brake pin is axially movably guided in a hub of the tourbillon unit or in the frame and is axially displaceable for the deflection of the brake element and for stopping the balance by means of the brake ring.
  • 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.
  • Fixradü is typically not only one, but there are several, approximately three circumferentially equidistantly arranged pawls are provided, which perform a synchronous, radially inwardly directed movement due to an axial movement of 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 decoupling of Tourbillontriebs can be done similarly by means of an inwardly controlled pivoting movement of coupling levers, which is for example preferably operated by pulling the winding crown from the second to the third axial position, and the one Axialverschiebung the second drive causes downward, so that it is no longer engaged with a coupling approach the Tourbillontriebs.
  • the Tourbillontrieb is decoupled from the drive force of the drive.
  • the crown is moved back into the second axial position, due to the force exerted by the clutch spring restoring force of Second drive again pressed against the coupling approach, and restored the coupling between them.
  • a watch in particular a mechanical wristwatch is provided, which is equipped with a previously described movement.
  • the present movement is composed as a classic movement with tourbillon, which also with a balance stop device (which is also often referred to as "second stop") as in the invention EP2793087 "Unruhstopp in the flying tourbillon" of the same applicant is described.
  • the tourbillon unit 1 has the same structure as an ordinary tourbillon, ie with a tourbillon driven by a bogie 1.03, which is also provided for the seconds display with an arrow 1.031, and in which a balance 1.01 or Balance spring 1.01a and escape wheel 1.04 are arranged.
  • the tourbillon unit 1 is preferably widened with a so-called retractable fixed wheel unit 1.10, and the tourbillon drive 1.21 is supplemented by a clutch.
  • FIGS. 1 & 2 each show a complete view of the top and bottom of the entire movement, which represents both the supplemented tourbillon unit 1 and the elevator and hand adjusting mechanism, and the circuit for the second stop and continue to set the tourbillon.

  • a pusher could alternatively be provided.
  • the present movement has according to the illustrated preferred embodiment, a three-stage elevator mechanism, as is common for watches with date quick adjustment on the winding crown.
  • a toothing on the angle lever 6.2 transmits the three possible axial positions of the winding shaft 6.1 on a camshaft 5, which has a gear 5.1. which cooperates with a toothing of the angle lever 6.2.
  • the camshaft 5 is composed of a first cam 5.3 for the balance stop lever (2.1,2.2) a second cam 5.2 for the retaining lever 3, and a third cam 5.4 for the clutch lever 5.4 and the gear 5.1 for the camshaft 5 together.
  • the respective cams are on each lever 2.4, 3.4, 4.4 respectively the balance stop lever 2.1 & 2.2, the Clutch lever 4.1 & 4.2 and the retaining lever 3 against their respective springs (ie reference numbers 2.3, 4.3, and 3.3) of the respective function opened and closed accordingly.
  • a first gear chain is present, which can be brought from the with a toothing of the clutch drive 6.7 first pointer wheel 6.4 via a second and third pointer wheel - each with reference numbers 25,26 - then with the hour wheel 29 and Combine 28 minutes.
  • a second transmission chain is also present, which can be brought here by the teeth of the clutch 6.7 first pointer wheel 6.4 via two successive Tourbillonstelltiv - each with reference numbers 12,13 - then with a second Tourbillonstellrad 11 and a first Tourbillonstellrad 10 mesh, which finally engages in the external teeth 1.10.1 of the disengageable Fixradä 1.10.
  • a rotational movement of the winding crown in this third axial position can be transferred to the disengageable Fixradä 1.10;
  • Such a transmission chain thus provides a preferred embodiment for the claimed adjustment device according to the present invention.
  • Figure 3 shows an exploded view of the tourbillon unit 1 of the movement, which highlights the structure of the disengageable Fixradiser 1.10 and the Tourbillontriebs 1.21.
  • the bogie 1.03 of the tourbillon unit 1, driven by the Tourbillontechnisch 1.21 is about the escapement with the escapement wheel 1.04, the pinion gears with the internal gear 1.10.2 1.10.2 of the removable Fixradiser 1.10 to the Umlaufrad 1.14 in the removable Fixradiser 1.10 with a revolution in 60 seconds (one minute), with the arrow 1.031 being the seconds display.
  • the disengageable Fixradä 1.10 thus applies as a fixed wheel for the tourbillon unit, as long as a holding lever 3, not shown on this figure presses on the circulating 1.12 of the planetary gear 1.14, and ensures that it thus rotatably with the board 2 remains.
  • the pawls 1.18, the stop ring 1.11, the two bolts 1.06 and 1.07, the hub 1.22, the spreading spring 1.09 and the ring 1.08 belong to a preferred embodiment of a balance stop device, as in the patent application EP2793087 "Unruhstopp in the flying tourbillon" published, and is therefore not described further.
  • the Tourbillontrieb 1.21 no longer integrally formed, but consists of several parts to allow decoupling with the second drive 1.21.3.
  • the tourbillon drive is rotatably mounted on a retaining pad 1.31, and rotates about the axis of rotation 1.20 of the entire tourbillon unit 1, which also corresponds to that of the balance 1.01 and the removable fixed wheel 1.10. It includes a shaft 1.21, a coupling lug, and a second drive 1.21.3 having a ramp to facilitate cooperation with the clutch levers 4.1.4.2.

  • When pulling out the winding crown of the second in the third axial position is a pivoting movement of the clutch lever 4.1 & 4.2 inward, which then pushes the second drive 1.21.3 down and breaks the friction clutch with the coupling approach 1.21.2, as later FIGS. 8A / 8B visible, noticeable.
  • the multi-part structure of the removable Fixradiser 1.10 is based on Fig. 5 clarified.
  • the disengageable Fixradiser 1.10 has a pulley 1.14, which has a central passage opening, which is bounded by an inner edge, and from which distributed ratchets 1.18 protrude radially inwardly. These are rotatable or pivotally mounted in the plane of the planetary gear 1.14 and are radially inwardly deflectable.
  • Each of the three pawls shown here 1.18 has at its free and inwardly projecting end on a Steueranlaufschräge 1.18a.
  • a dome-shaped latch cam 47 is formed in each case.
  • each of the pawls 45 is coupled to a pawl spring 1.19, by means of which the individual pawls are 1.18 deflected radially inwardly against a spring force. The radially inwardly directed deflection takes place via an axial force acting on the pawl cams 1.18b. With decreasing force the individual pawl springs 1.19 cause a movement of the pawls 1.18 radially outwards, in the on Fig. 4 shown starting position.
  • the disengageable Fixradiser 1.10 is, as in Fig. 5 shown, a circulating 1.12 trained. Axially displaced for this purpose, the removable fixed wheel unit 1.10 has an outer toothing 1.10.1. At the top of the turn-off Fixradiser a pulley 1.14 is arranged. The planet wheel 1.14 also has an annular contour. On an inner side of the peripheral wheel 1.14, a circumferential internal toothing 1.10.2 is formed, which, as already mentioned, meshes with the pinion 1.04a of the escape wheel.
  • a stop ring 1.11 On the underside of the removable Fixradiser 1.10 a stop ring 1.11 is also attached.

A radially inwardly directed pivoting movement of the pawls 1.18 thus leads to an upward, toward the bogie 1.03 directed axial displacement of the brake ring 1.08, whereby the brake pin 1.06 and herewith the brake spring 60 are axially displaced or axially deflected. Due to the radially inwardly directed pivoting movement of the pawls 1.18, the brake spring 1.05 finally engages with the double roller 1.02 of the balance 1.01.

  • the axial movement of the stop ring 1.11 leads, as already described, to the radially inwardly directed deflection of the pawls 1.18 and thus to an axial displacement of the brake pin 1.06 and ultimately to a balance 1.01 sustained deflection of the brake spring 1.05.
  • That one stop the movement 1 causing synchronous pivotal movement of the two first and second balance stop lever 2.1, 2.2 can be done by pulling a crown in a predetermined detent position. The movement is thus stopped. If the elevator crown, which is not explicitly shown here, is pulled out, starting from that stop configuration, into a further, for example, a second detent position, this causes a coupled pivoting of the holding lever 3, as on the FIGS. 8A / B.

  • the ratchet levers 2.1 and 2.2 are against the spring force of the spring 2.3 by the deflection at the first Cam 5.2 opened.
  • the stop ring 1.11 on the removable fixed wheel 1.10 is pressed by opening the latch 1.18 down.
