Definitions

  • the present invention relates to a tourbillon of a movement of a mechanical watch as well as to a movement equipped with such a tourbillon or a correspondingly equipped mechanical watch.
  • 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 gearwheel disposed coaxially with the balance axis, so that the tourbillon, and consequently its bogie, 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 back.
  • the DE 101 60 287 A1 a stopper for a tourbillon, which is an approximately V-shaped
  • Has double arm which is movable from a normal position radially outside a circumferential trajectory of the pillar of Tourbillongestells in a blocking position.
  • the double-arm spring In the blocking position, the double-arm spring is resilient against the circumferential direction of the contour of the balance directed spring arms on the radially encircling contour of the balance can be applied.
  • Such a radial intervention in the balance can prove to be a disadvantage for the extremely sensitive storage of the tourbillon on the one hand.
  • On the other hand can be influenced by an abutment position of the double arm with the radially encircling and radially outward contour of the balance, which are arranged on the rudimentary and provided for the regulation or adjustment of the balance weights, in terms of their location or orientation. It is to be feared that the double-arm spring affects the calibration or the highly sensitive adjustment of the balance and thus has adverse effects on the accuracy of the clock.
  • the CN 201 402 376 U further shows a stopping mechanism for a flying tourbillon.
  • two pliers are provided, which are radially engageable with a central shaft of the balance remote from the second drive. This, however, only an indirect operative connection with the clock-giving balance can be realized.
  • the escape wheel can be stopped and locked, which lock is to be transmitted via the anchor to the oscillating balance.
  • that stop mechanism when activated, may cause the balance to swing.
  • the present invention seeks to provide an improved balance for a tourbillon of a mechanical watch. This should be as simple as possible to integrate, for example, an existing tourbillon concept and, if possible, have little effect on the storage and positional stability of the tourbillon.
  • a tourbillon of a movement which has a connectable to a second drive of the clockwork or coupled bogie, which is rotatably mounted relative to a motherboard of the movement.
  • a balance wheel mounted with respect to a balance wheel and an escape wheel are rotatably mounted.
  • the escape wheel is in this case via an anchor in operative connection with the balance.
  • the balance, the anchor and the escape wheel form the inhibition of the mechanical movement.
  • the tourbillon is characterized in this case also by a bogie arranged, with the balance engageable and axially movable to the balance spring 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 brake element By the axially engageable with the balance brake element, the balance can also be braked directly via the brake element, in particular be stopped, whereby the rotational movement of the tourbillon, that is, the rotational movement of the bogie can be stopped.
  • a rest stop can be realized by the braking element acting in the axial direction, without this would have to be thwarted in the radial direction of the bogie of the tourbillon. Since the brake element occurs only with the balance, but not with the bogie of the tourbillon in direct operative connection, with the brake element provided here is also conceivable to realize a stop of a minute toaster, in which the bogie of the tourbillon could be rotated even when the balance is stopped.
  • the axially movable brake element allows the realization of a tourbillon, for example, for chronograph displays or for the realization of short-term measurements.
  • the braking element for stopping the balance is frictionally engageable with the balance in engagement.
  • the frictional force which can be exerted by the brake element on the balance can increase abruptly or steadily when the brake element is activated, so that a so far damped stopping of the balance can be realized.
  • the balance can be stopped in any position or configuration and irrespective of its instantaneous state.
  • the brake element on a first radially inwardly projecting portion on an axially aligned second friction surface, with a corresponding, axially aligned first friction surface of the balance is engageable.
  • the brake element extends in particular radially inward in the direction of the balance axis. It protrudes almost to the balance axis or its virtual extension and can there, for example by a directed in the axial direction against the balance movement or deformation, with the balance braking or retarding engage.
  • the substantially axially aligned first and second friction surfaces of the balance and the first portion of the brake element are characterized by a surface normal extending essentially in the axial direction, that is to say parallel to the balance axis.
  • a surface normal extending essentially in the axial direction that is to say parallel to the balance axis.
  • the brake element can also be a slightly deviating from the axial direction alignment for the provided on the first portion of the brake element second, namely, when the brake element at least partially pivoted against the balance or the brake element should be otherwise deformed in the axial direction ,
  • the braking element is in particular axially engageable with a lever plate or with a double role of the balance.
  • the brake element can be brought into engagement with a face of the lever disk or the double roller facing away from the balance or the ratchet wheel.
  • the first friction surface of the balance, which engages with the brake element is located on a front side of the lever disk or the double roller facing the brake element.
  • first and second friction surfaces of balance and brake element can have a friction-increasing surface finish, ie a predetermined roughness.
  • a friction-increasing surface finish ie a predetermined roughness.
  • the first, radially aligned to the balance axis portion of the braking element for at least partially enclosing the balance axis is fork-shaped or circular segment-like.
  • the first and second friction surfaces of brake element and balance, which mutually enter the contact position can be maximized, in particular for increasing a braking or locking function.
  • the geometric configuration of the fork-shaped, radially inwardly projecting free end of the brake element allows subsequent mounting of the brake element, such as the bogie of the tourbillon, especially when the balance is already mounted on the bogie.
  • the radially inwardly projecting, forked or circular segment-like end of the brake element can be adapted to the corresponding outer contour of the first friction surface of the balance, so that the largest possible surface portion of the rest first friction surface with the brake element is frictionally engageable.
  • the brake element can also be provided here to arrange the brake element on a radially and diametrically opposite the armature wheel side of the bogie. In this way, the center of gravity of the bogie can be further centered.
  • annular configuration of the brake element is conceivable, wherein the brake element then completely surrounds the balance axis and is mounted at least partially or completely axially displaceably relative to the balance axis.
  • the braking element has a second, radially spaced from the first portion second portion. With this second section, the brake element is fixed to the Bogie of tourbillon connected. Consequently, the brake element with the bogie also rotates about the balance axis, which typically coincides with the axis of rotation of the bogie.
  • the previously identified first and second portions of the brake member are free end portions of the brake member.
  • the brake element with its second, second end forming portion is fixedly connected to the bogie, the opposite end portion can be moved, for example, in the axial direction relative to the bogie and thus also against the balance.
  • a firm connection with the bogie is particularly easy to implement, for example with a screw. Due to its flexibility and a suitable choice of material for the brake element, the first portion can still be moved relative to the bogie at least in the axial direction.
  • the braking element is deformable against a restoring force in the axial direction.
  • the restoring force, against which the braking element is deformable in the axial direction, is hereby applied by the elastic properties of the braking element.
  • the braking element may be so far as a flexibly deformable leaflets or as a flexibly deformable spring, approximately comparable to a leaf spring, be formed, which is arranged only at one end, namely with its second portion on the bogie and there fixedly connected to the bogie.
  • the opposite end portion, thus the first, provided with a second friction surface portion of the braking element can then be moved flexibly in the axial direction, in particular in the axial direction with the balance in braking engagement.
  • the tourbillon bogie has a wheel-like or circular geometry with an outer rim or rim connected to a hub via a plurality of radially extending spokes.
  • the hub may in this case be rotationally secured connected to the second drive and coincide with respect to their axis of rotation with the balance axle or with their extension.
  • the braking element can be transferred by means of an axially displaceable relative to the bogie actuator in the axial direction of a release position in a braking or blocking position.
  • the actuator may in this case be designed to press in the axial direction against the brake member so that the first portion of the brake member away from the bogie and moves in the axial direction to the balance and with this, in particular with the lever pulley or double role engages.
  • the actuator is viewed in the radial direction between the first and the second section, or between opposite ends of the brake element. In this way, can be brought about by an axial displacement of the actuator, a flexible deformation of the brake element, by which the second friction surface provided with the first portion of the brake element with the balance is directly engageable.
  • the elastic deformability of the brake element can in this case also cause that the displaceable in the axial direction actuator in case of decreasing activation or deactivation by the restoring force of the brake element is again transferred back into an initial position.
  • the actuator is further held axially displaceable in a guide connected to the bogie.
  • the guide can in this case be arranged in the region of the hub of the bogie or be integrated directly into that hub.
  • the guide as well as the axially guided in the actuator and the brake element are thus arranged on the bogie of the tourbillon and rotate with this in the operation of the movement.
  • the actuator is axially supported on an axially displaceable against the guide ring.
  • the ring encloses the guide in a region facing away from the balance.
  • the actuator can be lifted by a directed towards the balance lifting the ring and thereby the brake element, are pressed about up against the balance, especially against the lever pulley or double role.
  • said ring is against a spring force axially in the direction of balance, in this case upwards, displaced.
  • That spring force can be provided for example by a spreading or disc spring, which is arranged axially between the ring and the guide, or the hub of the bogie.
  • the ring can be kept in one of the balance remote starting position.
  • an axial displacement of the ring against the force of that spring is provided, whereby ultimately the braking element can be raised axially.
  • the ring may, according to a development in particular with a plurality of actuators in operative connection, which are held about the circumference of the guide or over the circumference of the hub in the axial direction displaceable in corresponding guide receptacles.
  • a largely radially symmetrical lifting of the ring can be realized, so that the ring is guided in the course of axial movement relative to the guide or against the hub as well as possible and smooth and not prone to tipping.
  • the ring on its outer periphery facing away from the balance, such as at its lower radially outer edge on a run-on slope, which is formed corresponding to the run-up slope of a radially movable and engageable with the ring in contact position actuator.
  • the actuator may be configured for example in the form of a radially pivotable pawl.
  • the actuator may also be coupled via a lever mechanism with a pusher or with an angle lever. Finally, by a pusher or on the winding crown of the movement, the actuator can be moved in the radial direction, so that the latch-like run-up slopes of the actuator can lift the ring, comparable to a vertical chrono clutch.
  • the actuators may also be under spring bias and may each be coupled with one or more spring elements.
  • the tourbillon is designed in particular as a flying tourbillon.
  • the axial direction acting brake element is in particular integrable in already existing flying tourbillon concepts with little design effort.
  • the brake mechanism is barely visible from the dial side.
  • the brake system described here has no effect on the function of the tourbillon and its bogie while the clock is running.
  • a mechanical watch such as a wristwatch, a pocket watch or a wall clock which has a movement with a tourbillon described above.
  • a tourbillon 10 of a mechanical movement not shown in detail here is shown.
  • the tourbillon 10 has a bogie 6, which has a lower frame 60 with various radially aligned spokes 61, wherein on the outer ring of the lower frame 60 three distributed over the circumference of the lower frame 60 arranged pillars 62 are provided, to which an upper frame 64 is attached.
  • the racks 60, 64 are also rotatably connected to a flange-shaped hub 40, which, as in Fig. 3 shown rotatably coupled to the second drive 46.
  • the hub 40 thus the entire bogie 6 is rotatably mounted relative to a fixed wheel 50, which is also referred to as the lower block 50.
  • the fixed wheel 50 has, as in Fig. 3 shown at its top End portion of a flange-shaped gear portion 52 having a first outer toothing 54.
  • Gearwheel 15 and escape wheel 16 are arranged coaxially with each other and are both mounted on the bogie 6 via a first bearing 17, with that first external toothing 54 meshing with an escape wheel 16.
  • a rotation of the escape wheel 16 leads to a corresponding rotation of the entire bogie 6 with respect to the lower fixed wheel 50th
  • a balance 12 with a balance spring 14 of an escapement 11 is shown.
  • the balance 12 is hereby mounted on the bogie 6 via a balance bearing 18 which defines a balance shaft 28.
  • the balance bearing 18 is characterized by bearing journals 22, which cooperate with corresponding bearing-side arranged bearing stones 20.
  • the anchor of the escapement 11 is not shown in the present figures, so far the escapement 11 in the FIGS. 1 to 4 shown only partially.
  • a double roller 24 with a downwardly projecting front-side first friction surface 26 is provided below the ratchet wheel.
  • an axial gap between the first friction surface 26 and the hub 40 is formed. In that gap protrudes an axially acting brake element 30, which in the illustration according to the Fig. 1 and 3 flat on top of the lower frame 60 rests.
  • the brake member 30 is thus disposed below the bogie 6 and is located axially between the bogie 6 and the fixed gear 50. Therefore, the braking mechanism is hardly visible from the dial side view. This is particularly advantageous for aesthetic reasons, for a flying tourbillon that has no bridge and thus allows a complete view of the entire bogie without it being partially covered by another element of the board.
  • the integration of the braking mechanism is relatively simple, since the constructive engagement in an existing embodiment of a flying tourbillon is low.
  • the aesthetic advantages of the flying tourbillon over an ordinary tourbillon continue to be guaranteed.
  • the brake element 30 has a first section 30a, which is provided with an axial second friction surface 32 directed upwards toward the balance 12 and which, as in FIG Fig. 4 shown, from below against the first friction surface 26 of the double roller 24 can press.
  • the brake element 30 is presently designed as a kind of brake spring. It also has a second portion 30b opposite the first portion 30a, via which the brake element 30 is connected to the lower frame 60. As in the Fig. 1 and 3 illustrated, the second portion 30 b of the brake member 30 may be bolted to a spoke 61 of the lower frame 60.

In that recess, as in the 3 and 4 shown, an actuator 34 slidably guided in the axial direction. A lower end portion of the actuator 34 is radially tapered with respect to an actuator head 36 and is supported by a radial gradation on a hub 42 enclosing the ring 42 from.
  • a spring element 48 is arranged, which may be formed for example as a spreading spring. In this way, the ring 42 against the action of the spring element 48th be moved upwards and thus axially to the balance 12 out.
  • the axial displacement movement of the ring 42 leads to a corresponding axial displacement of the actuator 34, which is presently designed as an adjusting bolt.
  • an upper head 36 of the actuator 34 abuts an underside of the brake element 30 such that it lifts the radially inwardly projecting free end of the brake element 30 and thus its second friction surface 32 against a first friction surface 26 of the double roller 24 corresponding thereto suppressed. Due to the mutual friction between the second and the first friction surface 32, 26, the brake element 30 can develop a braking effect on the balance 12.
  • the ring 42 may be guided axially displaceably on the hub 40 via a plurality of bolts 34, 38.
  • the second bolt 38 is essentially without function with regard to the actuation of the brake device.
  • a particularly smooth, tilt-free axial displacement of the ring 42 relative to the hub 40 can be realized.

  • the actuator 34 undergoes a corresponding axial movement, which ultimately leads to the braking lifting of the radially inwardly directed free end portion 30a of the brake member 30.
  • the first and second actuators 70, 70a in particular their directly engaging with the ring 42 pawl 72 interact with another spring element 80 having two spring arms 84, 84a, each seeking to the pawls 72 radially inwardly to press.
