    Description Field of the Invention The present invention relates to the field of mechanical watches, in particular wristwatches, which are equipped with a digital time display by means of several dials.
    The present invention relates in particular to a timepiece according to the preamble of claim 1. This relates to a timepiece, in particular a wristwatch, with a digital display having a one-minute disc, a ten-minute disc, and an hour ring, as well as a timepiece a balance-spiral system and a gear train through which a one minute wheel of the one minute disc is rotatably indexable in cyclic increments of ten pitches per revolution, and a switch means whereby the ten minute disc is rotatably indexable with six pitches per revolution, the hour ring during a revolution of the ten-minute slice of the ten-minute slice via a Maltese intermediate wheel with twelve steps per revolution rotatable drehschaltbar, and with a manually operable disc interlocking, the movement at least one first spring barrel, a first gear chain and a second gear chain, wherein both transmission chains are connected to a release mechanism and the first transmission chain controls by means of the trigger mechanism, the second transmission chain such that the second transmission chain every minute, clocked via the balance-spiral system of the movement, a force in the form of a rotational movement of the One minute wheel transmits.
    BACKGROUND OF THE INVENTION AND PRIOR ART Already in the 16th century, clock-less watches appeared which indicated the time with moving or jumping numbers on rotating disks or rings. However, these were monumental clocks on towers or churches.
    In the second half of the 19th century, index pocket watches appeared digitally indicating both the hours and the minutes by mechanical jumping numerals, but the seconds were indicated analogously with a pointer. In particular, the factories IWC, Cortebert Watch, Gedeon Thommen, Aeby & Landry, Kaiser, u. a. m., such index pocket watches. The expert in the book "The Jumping Numerals Pocket Watches" by Alex Kuhn, Verlag Simonin, 2010. The first technical descriptions of this type of watch can be found in particular in the so-called Pallweber patents, see for example the German Reich Patent 25 042 from 1883.
    Meanwhile, these pocket watches have been substantially completely displaced from the market by mechanical watches with ana-log display. In the sixties also appeared cheaper electronic wristwatches with digital displays of any kind, which made a further development of mechanical watches with digital display prima facie little sense. In view of the current demands of the consumers on display accuracy and adjustability, the field of mechanical clocks with digital time display can thus be widely regarded as a new technical ground.
    A few innovations compared to the pocket watch production of the 19th century should be noted here: Patent DE 10 2007 042 797 discloses a watch, in particular a wristwatch, with a main power storage, through which via a gear train a Nachspannelement of a first Stepper-switchable device forming a Nachspannachse is rotatably driven by a Nachspannsteuerung in a cyclic steps controlled by a Nachspannachse and a connected at one end to the Nachspannelement memory coil spring is tensioned, the other end of the memory coil spring is connected to a clockwise rotatably driving wheel, the is engaged with the Rade movement of the escapement, wherein by a Elément the gear train from the main power storage to Nachspannelement another step-switching device is rotatably driven in cyclic steps. The clockwork of this timepiece is mainly used in so-called clockworks with constant torque and therefore, in order to avoid large torque fluctuations, has a tensioning device that charges the accumulator coil spring at regular intervals.
    The patent DE 10 2009 019 335 discloses a watch, in particular a wristwatch, with a drive through which a gear train of a plurality of dials digital display is rotatably driven in cyclic steps, wherein a single gear of a Einerminutenscheibe with ten steps per drive wheel Rotation rotatably rotatable, with a driven by the one-gear switching device, through which a ten-minute disc with six steps per revolution is rotatably drehschaltbar and with a hour dial which is rotatably rotatable during a revolution of Zehnerminutenscheibe of Zehnerminutenscheibe with twelve steps per revolution, through a manually drivable Scheibenstellrad a drive which engages in the gear train is driven, wherein the drive is coupled via a control gear frictionally connected to the drive wheel.
    The realized by said Stellwerksperre coupling between the manually driven by the Scheibenstellrad drive and the drive wheel of the wheel of this clock has a specific configuration and is mounted in particular axially slidably on the axis of coaxial with the drive wheel arranged drive, wherein the Rade factory designed to save space and reduce the number of components as a continuous gear train with successively driven dials is designed.
    Swiss Patent Specification CH 511 471 discloses such a watch, wherein a one-minute disc is rotatably rotatable with ten steps per revolution, with a switching device, through which a ten-minute disc with six steps per revolution is rotatably indexable and with a hour-hand dial, which is rotatably indexable during a revolution of the ten-minute slice of the ten-minute slice with twelve steps per revolution. The factory has a first transmission chain which transfers the power from a first barrel to a first inhibition of a regulator of the watch, and a second gear chain which transfers the power from a second barrel to the indicator discs, the rotation of the gears of the second gear chain of a wheel of the first transmission chain is controlled. The consequent blockage of the second gear chain between the indexing steps of the display discs and their release at the time of sequencing is accomplished via a second anchor of a second escapement in cooperation with superimposed, mutually rotatable plates, which requires a relatively complex structure of the movement.
    In the Swiss patent specification CH 581 857 a spring mechanism of a clock of this type is disclosed, wherein a gear of a display dial cam with a pointer wheel, which is mounted on a rocker. A lug of the rocker engages a toothing of the disc, however, the lobe is released from the toothing both during a manual correction operation and by automatically displacing the rocker during the normal course of the watch.
    The European patent application EP 3 032 348 also discloses a spring mechanism comprising a drive wheel, a time display, and a bouncing member mounted on said time display and coaxial with the drive wheel, and a cam thus configured to release a four arm anchor once per unit time. This arrangement is especially designed for displays that make a sudden change every second, in particular using a single power source in the movement.
    OBJECT OF THE INVENTION In spite of the prior art, it is further desirable to have a watch of the generic type which minimizes the amplitude of the balance-spiral system as the display discs are rotated relatively gradually relative to hands the frequency of the regulating mechanism of the movement, having as much precision as possible the gradual rotation of the display discs, having a simple and robust system for said stepwise rotation of the display discs and for securing them between the indexing steps, a manually operable disc interlocking , which allows adjustment of the clock in both directions and at the same time realizes a safe adjustment process without the possibility of damage to the clock mechanism, has - an aesthetically pleasing time display with reasonable space requirements of the display discs and thickness of the timepiece ks, as well as all this - a simple assembly is allowed and represents a solution suitable for mass production.
    The object of the present invention is therefore to avoid the disadvantages of the previous embodiments, the Ver-realization of the above advantages, and to provide a clock, which has a multi-dials aufweisend digital display, the dials triggered instantaneously and should be indexable with as little energy as possible. In particular, the dials should stop for one minute, while at the end of each minute, as soon as the second hand reaches sixty seconds, the one-minute dial should be immediately released and rotated one more position. At the end of ten minutes, the ten-minute disc should be additionally rotated and, at the end of one hour, the hourly disc rotated one more position. Another object of the present invention is to provide a manually operable disc interlock to safely set the time in both directions. Another object of the present invention is an attractive digital time display in the context of mechanical wristwatches. This is to be achieved by using a constructionally simple and sturdy designed movement, which ensures a safe operation.
    Summary of the Invention The object of the present invention is characterized by the features mentioned in the characterizing part of claim 1. According to a first aspect of the invention, in a timepiece according to the invention, the axes of the one-minute and ten-minute disks are parallel to each other and inside the hour-pulley, the one-minute disk being formed in two stages and the edge of its upper, number-bearing stage being the edge of the ten-minute disk opposite, so that the surfaces of the two discs are in the same plane.

In particular, provide a trigger mechanism with a control disc, two release levers each having a first and a second lever arm, and a release wheel, the first lever arms of the two trigger levers being staggered and bearing against the circumference of the control disc such that that at the end of each minute, the first lever arm of one of the trigger levers falls from the control wheel edge into a recess in the control disk and the second lever arm of this trigger releases the release mechanism of the trigger mechanism so that the second transmission chain turns freely until one tooth of the trigger wheel on the second lever arm of the other Trigger lever strikes, with the one-minute wheel and the one-minute disc rotates one step further. Preferably, in this case, the first gear chain has a large base wheel driven by the first barrel, a small-plate gear driven by the large-diameter gear, and an intermediate gear meshing with the small-plate gear, said control disc being fastened to the axis of the intermediate gear.
    By these features, a number of advantages are achieved, in particular the amplitude fluctuations are kept low in the balance-spiral system and it is possible to implement sixty triggers per hour with a comparatively simple assembly, in particular thanks to a than 30 Stepped pulley or a control disc designed as a two-part cam and two associated levers, which has the advantage that the steps or sections can be made larger, which in turn causes a safer operation.

    DETAILED DESCRIPTION OF THE INVENTION Two embodiments of the invention will now be described in detail below with reference to the drawings.
    A digital display 10 with a disk rotation drive and release system according to the present invention is intended for integration into a wristwatch. As shown in FIGS. 1 a, 1 b and 1 c, the digital display 10 comprises a one-minute disk 11, a ten-minute disk 12 and an hourly disk designed as an hour ring 13. The axes of the one-minute disc 11 and the ten-minute disc 12 are arranged parallel to each other and inside the hour ring 13, these axes being perpendicular to the plane of the digital display. The Einmininutenscheibe 11 is formed at least two stages, the edge of its upper digit-bearing stage of the edge of the ten-minute disc 12 is opposite and the surfaces of the two discs 11,12 lie in the same plane.
    The three display discs 11, 12, 13 of the digital display 10 are connected to each other via a switching device, which is formed in this embodiment as a Maltese transmission. This is made up as follows: The lowest stage of the one-minute disc 11 carries a roller 15 which engages in the Maltese track on the underside of the ten-minute disc 12 and carries it with the number "9" to the number "0" when the one-minute disc 11 is shifted. wherein a rotation of the Einmininutenscheibe 11 by 36 ° causes a rotation of the Zehnerminutenscheibe 12 by 60 °. Stand the display discs as shown in Fig. 1a, that is shortly before the circuit of Zehnerminutenscheibe 12 of the numeral «5» to the numeral «0», then engages a pressed-in pin 16 of Zehnerminutenscheibe 12 in the Malteserkon-tur of the Maltese intermediate wheel 14 a and rotates this at the circuit of the ten-minute disc 12 from the numeral "5" to the numeral "0" through the Einmininutenscheibe 11, whereby a rotation of the Maltese intermediate wheel 14 is effected by 72 °. By the rotation of the Maltese intermediate wheel 14 slides one of the bottom at regular Winkelabstânden positioned Ftollen 17 of the Maltese intermediate wheel in the Maltese groove of the hour ring 13 and also switches this by one position, which corresponds to a rotation of the hour ring 13 by 30 °. The Ein-handles of this Geneva drive are shown in Fig. 1c in a position during the switching operation. After completion of each switching operation, the respective locking radii 18 of the Maltese contours of the display discs 11, 12, 13 face each other again and hold the display discs of the digital display 10 in position. In general, it should be noted here that the components 15, 16, 17 are executable both as rollers and as a pin, the choice depending on the available thickness of the associated disc stage. If the thickness is sufficient, it is preferred because of the better Ftei-bungsverminderung execution as Ftolle.
    A first embodiment of a movement of a clock housing this digital display 10 will now be described in the following with reference to FIGS. 2 to 4. This plant, on the one hand, has a walking gear which comprises a first conventional gear chain 20 and a first barrel 21, as is also used in a conventional movement according to the prior art. In this movement, the power is transmitted from the first barrel 21 via Zahnrâder with · each attached drives, in particular a minute wheel 22, a Kleinbodenrad 23 and a second wheel 24, to an escapement 25 and a balance-spiral system 26 of the movement. In addition to the power transmission, in the prior art, this transmission chain would have the task of controlling the hands or other displays. In contrast, according to the present invention, a movement has, on the other hand, a derailleur which comprises a second transmission chain 30 and a second spring 31 with associated transmission gear. These two transmission chains 20,30 are interconnected by a release mechanism 40, wherein the first transmission chain 20 of the movement controls every minute, clocked via the balance-spiral system 26, by means of the release mechanism 40, the second transmission chain 30 of the derailleur. This second transmission chain 30 transmits the force from the second barrel 31 in the form of a rotational movement to the display discs 11, 12, 13th
    In order to ensure a high triggering precision during the switching operation of the digital display 10 and at the same time to minimize amplitude fluctuations in the clockwork balance control system 26 in this embodiment, the release mechanism 40 is shown in Figs. 3a to 3c , A control disc in the form of a stepped disc 41 with thirty each having a step and a recess or gap having sections with a total width winkelbreite of 12 °, wherein the stepped disc 41 is fixed to the axis of the minute wheel 22. The Auslôseme-mechanism 40 also has two shown in Fig. 4 in a detailed view, pivotally mounted release lever 42, 43, each with two lever arms, the first lever arms are guided by one Auslôsefeder 46 against the circumference of the stepped disk 41 and with slight pressure this rest. The release levers 42, 43 are positioned offset relative to one another about the circumference of the stepped disk 41 in such a way that the ends of their first lever arms are offset or engaged by half a pitch of the stepped disk 41, as shown in FIG. 3b is apparent. By this arrangement, it is possible to implement sixty triggers per hour with a 30-stage stepped disk 41, which has the advantage that the stages can be made larger. The triggering mechanism 40 further has a tripping wheel 44 which is released or blocked by the second lever arms of the tripping levers 42, 43, depending on their location about the circumference of the stepped pulley 41.
    The total angular width of 12 ° of the portions of the stepped pulley 41 may preferably be divided asymmetrically to further increase the reliability of the release mechanism 40. For example, the angular width of the step shown in Figs. 3a and 3b is preferably in the range of 6.1 ° to 10 ° and that of the gap in the range of 2 ° to 5.9 °, ensuring that just before the start of the triggering process, that is, shortly before the fall of the first lever arm of one of the tripping levers 42, 43 into a gap of the stepped disk 41, the first lever arm of the other tripping lever 42, 43 has already assumed its final position on the stage. Of course, the above-mentioned angle width can be selected differently depending on the configuration of the stepped pulley 41. Furthermore, the release levers 42,43 can advantageously be designed so that their first and second lever arms, which preferably each correspond to a short - and a long lever arm, at both Auslösehebeln 42, 43 are each the same length. Preferably, for each release lever 42, 43 also on the short lever arm an eccentric 45 is provided, which at the end of the Auslôsevorgangs, that is, during the fall of the first lever arm of the tripping lever 42, 43 in a gap of the stepped disk 41, the opening of this first lever arm prevented at the bottom of the stepped disk 41. This makes it possible to reduce the wear on the stylus tips of the release levers 42, 43.
    During the normal course of the movement, the stepped pulley 41 continuously rotates with the minute wheel 22, with the first lever arms of the two release levers 42, 43 sliding over the surface of the outer periphery of the stepped pulley 41. At the end of each minute, the first lever arm of one of the tripping levers 42, 43 falls from the step disc edge into a gap of the stepped disc 41 and releases the tripping wheel 44 by means of its second lever arm. This allows the second transmission chain 30 of the derailleur to rotate freely until the tooth of the trigger wheel 44 engages the second lever arm of the other trigger lever 42, 43. Thus, the one minute disc 11, which is preferably directly mounted on or in kinematic connection with a one minute wheel 36 of the second transmission chain 30 of the derailleur, rotates one step further, corresponding to a rotation of 36 °, and respectively the next digit on the one minute disc 11 can be seen in a window, not shown in the figures in the dial of the clock.
    A second embodiment of a movement of a clock housing the digital display 10, which has a further improved triggering accuracy, will now be described below with reference to FIGS. 5 to 8b. Similar to the movement of the previously described embodiment, according to the second embodiment, as shown in FIGS. 5 and 6, the movement has, on the one hand, a walking mechanism comprising a first transmission chain 50 and a first barrel 51. In this movement, the force from the first barrel 51 via Zahnrâder with each attached thereto drives, in particular via a below also referred to as Grossbodenrad minute wheel 52, a Kleinbodenrad 53, an intermediate drive 54, a Kleinbodenzusatzrad 55, and a second wheel 56, an escapement 25 and a clockwork balance-spiral system 26 transmitted. Compared to a conventional Rade factory of a vehicle, the Kleinbodenrad 53 was supplemented with the attached Kleinbodenradtrieb by a loosely mounted on the Kleinbodenradtriebes and therefore freely rotatable Kleinbodenzusatzrad 55. The wound barrel 51 is the force of its coil spring or tension spring as torque on the large bottom wheel 52 to the Kleinbodenradtrieb the Kleinbodenrads 53 on, so that the riveted on the axis of the Kleinbodenradtriebs Kleinbodenrad 53 is rotated. This, in turn, transfers the torque to the intermediate drive 54, which carries a control disk in the form of a cam 71 and transmits the torque to the low-floor auxiliary 55 mounted loosely on the low-floor gear drive, which engages the second-wheel drive of the second wheel 56. From here, torque transmission continues in a conventional manner to the escapement 25 and the clockwork balance control system 26.
    In contrast to the release mechanism 40 according to the first embodiment of a movement according to the invention, in which the tap of Auslosezeitpunkt of the minute wheel 22, and the stepped pulley 41 attached thereto, takes place, the tap of Auslosezeitpunkts takes place in the second embodiment of a movement according to the invention from the small bottom wheel 53rd in that the cam disc 71 is fastened to the intermediate drive 54 which cams with the low-order wheel 53. The available torque is somewhat lower than the first embodiment of a movement according to the invention, but is sufficient and higher than the torque on the secondary wheel 56. On the other hand, this advantageously enables the speed of the cam 71 of the second embodiment of a movement according to the invention, which is in the stepped pulley 41 of the first embodiment at one revolution per hour, be significantly increased to one revolution per four minutes, since the change of the Rade 50 by receiving the intermediate drive 54 and the loosely mounted Kleinbodenzusatzrads 55 a changed and selectable within certain limits Zhhnezahl or Translation is allowed on these wheels. The number of sections each having a tooth and a recess on the cam 71 is accordingly selectable, the cam 71 of the second embodiment of a movement according to the invention, as shown in FIGS. 5 and 6, having two such sections. The attached to the intermediate drive 54 cam 71 can therefore be directly and without play in the power flow of the first transmission chain 50 despite the increased speed in an advantageous manner.
    On the other hand, like the first embodiment of a movement according to the invention, a movement according to the second embodiment of the present invention has a derailleur which, as seen in Fig. 5, comprises a second transmission chain 60 and a second spring housing 61 with associated transmission gear. The two transmission chains 50, 60 are interconnected by a release mechanism 70, wherein the first transmission chain 50 of the vehicle controls the second transmission chain 60 of the derailleur by means of the release mechanism 70. This second transmission chain 60 transmits, analogously to the relevant description of the first embodiment, every minute, clocked via the balance-spiral system 26, the force from the second spring 61 in the form of a rotational movement to the Einerminutenrad 66 and thus to the display discs eleventh , 12, 13, which allows their gradual progression.
    The release levers of the release mechanism 70 are analogous to those of the first embodiment ge-staltet and are configured as pivotally mounted release lever 72, 73, each with a first and a second lever arm, which preferably each correspond to a short and a long lever arm, with the difference that the axes of both levers are arranged coaxially. One of the tripping levers 72 is fixedly connected to an associated shaft serving as a pivot axis, and the other tripping lever 73 is loosely and freely rotatably supported on the pivot shaft and axially secured with a bush, as schematically shown in FIG. With this arrangement, in the release mechanism 70, instead of the two trigger springs 46 of the release mechanism 40 of the first embodiment of the movement, only one trigger spring 76 designed as a tension spring is needed which presses the release levers 72, 73 against the cam 71. In the assembled state of all components of the release mechanism 70 in the factory Auslôsefeder 76 is always slightly biased, which ensures that the two release levers 72, 73 abut either the cam 71 or on one of each Ausloshebel 72, 73 provided eccentric 75 , as shown in Fig. 8a can be seen. As in the first embodiment, the eccentric 75 in this embodiment also have the task of sparing the stylus tips at the ends of the first lever arms of the two release levers 72, 73 and not let them strike the bottom of one of the recesses of the cam 71. By analogy with the division of the sections of the stepped disc 41 of the first embodiment, the pitch of the sections of the cam 71 may also be asymmetrically designed to ensure that shortly before the start of the triggering operation, that is shortly before the first lever arm drops, one of the trigger levers 72 , 73 of one tooth of the cam 71 in its subsequent depression, the first lever arm of the other trigger lever 72, 73 has already reached its final position on the circumference of the cam 71 to ensure the reliability of the release mechanism 70 in the same way. The release mechanism 70 further has a release wheel 74 which is released or blocked by the second lever arms of the release levers 72, 73, depending on their location around the circumference of the cam 71, and thereby, analogous to the above in connection with the second transmission chain 30th The first embodiment described causes, by means of the second transmission chain 60 of the derailleur, the gradual indexing of the dials 11, 12, 13 of the digital display 10.
    In the following, the manually actuated disc interlocking, which allows the manual adjustment of the position of the dials 11, 12, 13 of the digital display 10, will now be described with reference to FIGS. 9,10a and 10b. As can be seen in FIG. 9, the disc interlocking has a plurality of pointer adjusting wheels 81, 82, 83, 84, 85, which are in each case in series with one another, which can be moved by an elevator shaft 77 in its withdrawn position by means of a clutch lever 79. The disc interlock can be actuated by pulling the elevator shaft 77, whereby an angle lever 78 is rotated. The latter pivots the clutch drive lever 79 via its outer shape. The one end of the clutch drive lever 79 engages in the groove of a clutch drive 80. In the withdrawn position of the elevator shaft 77, the aforesaid parts occupy the position shown in FIG. 9, so that the hand setting wheels 81, 82, 83, 84, 85 can be rotated by manually rotating the elevator shaft 77. The last hand wheel 85 is fixedly mounted on the Einininutenscheibe 11 and this assembly is loose and freely rotatably on the Zwischenradt-rieb 86, which is part of the second transmission chain 30, 60 of the derailleur.
    The journal of Zwischenradtriebs 86 is, as shown in Fig. 10a or 8b, at the end formed as a positive connection and includes a threaded hole, these two elements serve a Stem 87, which limits the Hьhenspiel the Einerminutenscheibe 11, the Zwischenradtrieb 86 to install and index. The Stem 87 has ten teeth. As shown in Fig. 10a and 10b, a detent spring 88 is also attached to the Einerminutenscheibe 11, for example screwed with screws 90, wherein the detent spring is formed conjugate to the shape of the stem 87 and consists of several, combined in one component functional parts. This detent spring 88 can be rotated by a certain angle by means of an eccentric 89, which is pressed on the Einmininutenscheibe 11. By the interaction between the stem 87 and the detent spring 88, the Einerminutenscheibe 11 is aligned exactly in the dial window on the one hand. On the other hand, the stem 87 and the detent spring 88 form a frictional coupling which, in the presence of a higher force than the detent spring force, permits a relative adjustment in ten steps between the idler gear 86 and the last dial gear 85 fixedly attached to the one minute disc 11. At this point, for the sake of completeness it should be noted that both the Zwischenradtrieb 86 and the Zeigerstellrad 85 with the in the above description of the two embodiments of the movement according to Fig. 2, and according to Fig. 5, as Einerminutenrad 36, 66 designated part functionally equated can be.
    Once the elevator shaft 77 is rotated in its pulled-out position, via the above-mentioned and shown in FIG. 9 Ràderkette from the elevator shaft 77 via the clutch drive 80 and the Zeigerstellrâder 81,82,83,84, 85 Einerminutenscheibe 11 put in a rotary motion. The detent spring 88 jumps from a tooth gap of the stem 87 to the next, so that the desired time can be set. Once the rotation of the elevator shaft 77 is stopped at any time, the detent spring 88 slides into the nearest gap of the star 87. The disc interlock including the clutch consisting of the star 87 and the detent spring 88 is designed to set the time in both directions.
    Preferably, the disc interlocking further comprises a blocking device, wherein a corresponding embodiment of the device will now be described with reference to FIGS. 11, 12a and 12b. During clockwise adjustment, a rotational torque acts on the second transmission chain 30, 60 of the derailleur, this rotational movement being blocked by one of the two trigger levers 72, 73 as shown in the above description of the movement. But if the time is set counterclockwise, the torque acts against the direction of rotation of the wheels in the second transmission chain 30, 60 of the derailleur, which would rotate the entire gear backwards, which could cause damage to the release mechanism. In order to prevent this, the disc interlocking preferably has a special device which blocks the Zwischenradtrieb 86 in a counterclockwise clock setting. This locking device has a pivotable from the Kupplungsstriebhebel 79 stop lever rocker 91, at its two free ends a pin 92, 96 is mounted, one of the stop lever rocker 91 acted upon the balance of the clock stop spring 93, and a movably mounted and the stop lever rocker 91st displaceable blocking lever 94, wherein a toothing 95 of the blocking lever 94 engages in dependence on its location in the teeth of the Zwischenradtriebs 86 and the latter, as shown in FIG. 12a visible, blocked or, as in Fig. 12b visible, releases. If, as described previously, the elevator shaft 77 is pulled out and all parts moved accordingly, in the presence of the blocking device, the stop lever rocker 91 is additionally set in rotary motion via the clutch drive lever 79. As a result of this movement of the stop lever rocker 91, the stop spring 93 is bent against the balance wheel by means of the pin 92 which is pressed in at one of its free ends, visible in FIG. 11, so that the balance is stopped. At the same time causes the pressed at the opposite free end of the stop lever rocker 91 pin 96 when moving the stop lever rocker 91, a linear displacement of the movably mounted and hinged to said pin 96 blocking lever 94. The linear path of the blocking lever 94 is designed so that its fine teeth 95 in the Zhne the Zwischenradtriebs 86 engages and blocks it against any further rotation, so that the second transmission chain 30, 60 of the rear derailleur at a reverse rotation of the winding shaft 77 can rotate only minimally. On the other hand, if the stop lever rocker 91 is in its normal, undeflected position, both the balance wheel and the intermediate wheel drive 86 are freely pivotable or rotatable. At this point, it should be noted that the configuration of the blocking lever 94 can be adapted according to the force conditions and the blocking lever 94, for example, as shown in Fig. 12c, only a projection or, as shown in Fig. 12d, an elastic leaf spring without Gearing, which rests in the blocking position of the blocking device on the teeth of the Zwischenradtriebs 86 may have.
    After explaining the construction of the disk interlocking, the elevator of the spring houses 21, 31, 51, 61 will be explained in more detail for the sake of completeness of the description of the present invention by means of the figures 13, 14a and 14b. The two spring houses 21, 31, and 51, 61 of the movement and the derailleur of the movement are wound up as follows. By rotating the elevator shaft 77 in its non-pulled position, the clutch drive 80 is taken over a square of the elevator shaft 77, wherein the clutch drive 80 transmits this rotational movement via its locking teeth on the elevator drive 97. As a result, as shown schematically in FIG. 13, all other elevator wheels 98, 99, 100, 101, 102, 103, 104 which rotate in series rotate, wherein the two elevator wheels 103 and 104 are connected to the spring housings 21, 31, 51, 61 by means of positive locking. The manual wind has only a locking cone 105, which is rotated by a spring 106 against a ratchet wheel 107, as shown in Fig. 14a and 14b can be seen. The locking cone 105 prevents the first spring 21, 51 from tensing again, whereby the second barrel 31, 61, since it is connected via the Aufzugrâder 102, 103,104 connected to the barrel 21,51, is also locked on the locking cone 105.
    The spring houses 21,31,51,61 are preferably designed so that they, · even in the case of equal length spiral or tension springs in the first - 21, 51 and in the second barrel 31, 61, run at different speeds and therefore do not have the same speed, in particular such that the second barrel 31, 61 has a lower speed than the first barrel 21,51. This can ensure that there is always enough force on the second barrel 31, 61 to switch the indicator discs 11, 12, 13 of the digital display 10 until the watch has reached its power reserve. Thus, the clock, respectively the spring houses 21,31,51,61, can always be fully wound up, it has two elevator springs with a known to those skilled Gleitbride. Optionally, the first barrel 21, 51 can also be provided with a spiral or tension spring with a fixed stop for a manual winding.
    Finally, it should be expressly noted at this point that the above-described two embodiments can be easily simplified by a skilled in the watchmaking industry in that instead of a first - 21, 51 and a second barrel 31, 61, the each serves as a separate source of energy for the Geh-, respectively the rear derailleur, only a single barrel is used, which serves as the only source of energy for the entire Ràderwerk the simplistic movement. The resulting third and fourth embodiment of a movement according to the invention, which, according to the above description, have a release mechanism mounted either by means of a stepped disc 41 mounted on the minute wheel 22 or by means of a cam 71 located on the intermediate drive 54 additionally inserted in the wheel drive Therefore, in view of the above description, no further explanation and are not shown in the accompanying drawings, without affecting the extension of the present invention also to these embodiments.
    A timepiece according to the present invention has a number of advantages. The release mechanism of a movement according to the invention consists in particular only of a control disk, two Auslosehebeln, each with a first and a second lever arm, and a Auslôserad, the control disk is mounted on an additionally mounted in the first transmission chain intermediate drive, resulting in a simple and space-saving design and leads to a safe functional sequence. In the case of the preferred use of two spring housings in the movement, these guarantee a safe transfer until the end of the power reserve of the timepiece, the release mechanism realizing safe control of the derailleur by the movement. Any amplitude fluctuations in the balance-system are thereby kept low. The associated disc interlocking, which has a simple coupling between the Zwischenradtrieb and the Einmininutenscheibe, allows safe adjustment of the clock in both directions and can optionally with a blocking device of Zwischenradtriebs, which blocks when setting the clockwise counterclockwise said Zwischenradtrieb equipped become. Furthermore, the elevator device is robust, can be implemented in a relatively simple manner, and is characterized by a safe functional sequence. The arrangement of the axes of the one- and ten-minute disks parallel to each other and inside the hour ring realizes a aesthetically pleasing digital time display for mechanical watches and allows a certain freedom in the arrangement of the time display on the clock dial.
