    The invention relates to a step-switching device for cyclically indexing a dial of a digital display of a clock, with a display control drive which is rotatably mounted on a first shaft and rotatably driven in cyclic steps, wherein of the display control drive arranged on a second shaft Anzeigeeantriebsrad and with the indicator drive wheel, the second shaft is rotatably driven, with a arranged on the second shaft and rotatably driven by the second shaft drive, of which on a third shaft or a rotatably mounted dial washer hub fixedly arranged, uniformly distributed on its circumference numerals or numbers carrying dial gear is rotatably driven, wherein the third shaft or the rotatably mounted dial hub carries the dial.
    The number or number to be displayed in each case is visible through a window of a cover for an observer. In such stepping means, an incident may occur at the display control drive at the beginning of a step, resulting in an oblique position of the digit to be displayed.
    The object of the invention is therefore to provide a stepping device of the type mentioned, which leads to a correct orientation of each displayed digit or number.
    This object is achieved according to the invention that the drive to a lot freely rotatably mounted on the second shaft and the third shaft or a rotatably mounted dial disc hub is rotatably driven in a number of locking positions, the number of radially circumferentially on the dial arranged numbers or numbers corresponds.
    In a continuation of the incident is first compensated by the lots, so that it comes by the incident to no obliquity of the number or number to be displayed. Then, when the dial is finished, the detent positions also correct the positioning of the dial and restore the lots.
    The drive can be arranged freely rotatable on the second shaft to a lot between 2 ° and 10 °, in particular between 3 ° and 5 °.
    In a simple embodiment, the lots is generated in that a driver is firmly connected to the second shaft, which projects in a radially circumferential direction with play in a slot-like recess of the drive.
    For this purpose, a drive plate may be rotatably disposed on the second shaft, which has a drive shaft parallel to the second shaft, which projects into the slot-like recess of the drive.
    For driving in the respective correct latching position can be rotatably arranged in a simple manner on the third shaft or a rotatably mounted dial disc hub, which has a detent recess contour on its radially circumferential surface, which evenly distributed on the circumference has a number of locking recesses, which corresponds to the number of radially circumferentially arranged on the dial numbers or numbers and in the radially engages a catch resiliently.
    It requires little space, it is when the catch is arranged at the free end of a spring arm, the other end is fixed.
    In order to enable a fast, at least largely free of frictional losses locking, the catch can be a freely rotatable about a third shaft or to the rotatably mounted dial washer hub axis rotatable detent roller.
    In this case, it leads to an exact positioning of the dial when the locking recesses have a V-like cross section, the flanks of the catch lead to the lowest position in the detent recess, which also defines the exact position of the dial.
    The dial can be a one minute slot or a ten minute slot.
    The display control drive may have a single or multi-toothed control drive, in the tooth circulation area a blocking element in the cyclic steps on and can be swung out.
    Particularly space-saving, it is when the step-switching device is rotatably driven by a stepping device in cyclic steps through which a driven shaft formed by the Nachspannachse a Nachspannwerks in steps rotatably drivable and a memory coil spring of the restraint is nachspannbar, then both the cyclic progression the dial and the retightening of the memory coil spring of the tensioning device by a single step switching device takes place.
    In this case, the stepper can have any suitable training.
    An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it<Tb> FIG. 1 <SEP> is a view of a stepping device for a stepping device of a dial and a memory coil spring of a tensioning device<Tb> FIG. 2 <SEP> is a perspective view of the indexing device of a dial according to FIG. 1<Tb> FIG. 3 <SEP> a side view of the step-switching device of a dial according to FIG. 1<Tb> FIG. 4 <SEP> an enlarged section "X" from FIG. 1.
    In Fig. 1 of a barrel 1 via an intermediate pinion 2, a first Kleinbodenrad 3 is rotatably driven, which is fixedly arranged on a drive shaft.
    The first Kleinbodenrad 3 engages in a display control drive 5, which is rotatably mounted on a first shaft 6, at one end of a single-toothed control drive 7 is arranged rotationally fixed.
    Of the display control drive 5, a display drive 8 is rotatably driven, which is fixedly arranged on a second shaft 9, which rotatably carries a drive plate 10.
    Parallel to the drive plate 10, a drive 11 is freely rotatably mounted on the second shaft 9, which has a concentric slot-like recess 12, in which a fixedly arranged on the drive plate 10, the second shaft 9 parallel driving pin 13 with a lot bildendem Game protrudes in the direction of rotation, so that the drive 11 can rotate by 4 ° relative to the drive plate 10.
    The drive 11 in turn engages a dial gear 14 which is fixedly mounted on a number plate hub 38, which also carries a Einerminutenscheibe 16 for displaying the minutes. The number plate hub 36 is freely rotatably mounted on an axle 15. On the one-minute disc 16, the numbers 0 to 9 are arranged distributed radially all around. The number of each minute to be displayed is then visible through a window in a cover, not shown, for an observer.
    On the number plate hub 38, a locking hub 17 is further arranged non-rotatably, evenly distributed on its radially circumferential surface corresponding to the number of digits on the Einerminutenscheibe 16 ten locking recesses 18 which have a V-like cross-section.
    Tangential to the locking hub 17, a spring arm 19 is arranged, which is fixedly disposed with its one end to a fixed component of the clock. At its other, free end is arranged around a parallel to the axis 15 locking roller axis 20 freely rotatable detent roller 21 which is pressed by the bias of the spring arm 19 against the radially encircling lateral surface 22 and can engage in the locking recesses 18.
    The one-toothed control drive 7 is released by a step switching device once per minute for one revolution. This leads to an incident in which the single-toothed control drive 7 performs a jerky rotational movement of about 20 °. The translation makes the display drive wheel 8 rotate about 4 °.
    The drive plate 10 makes the rotational movement of the Anzeigeeantriebsrades 8 and the second shaft 9 with. Only after overcoming his game in the slot-like recess 12 of the driving pin 13 takes the drive 11 with, then the dial gear 14 and the locking hub 17 to drive.
    In the rotary drive after the incident, the detent roller 21 is lifted out of a detent recess 18 by the ramp-like flanks upon rotation of the detent hub 17 and migrates on the cylindrical surface 22 between the locking recesses 18 along to the next detent recess 18th
    Since the display drive wheel 8 due to the game of the driving pin 13 in the slot-like recess 12 during the switching operation is no longer made the complete rotational movement, the detent roller 21 does not fall to the bottom of the next detent recess 18 but initially remains on the ramp-like edge of the detent recess 18 stand. Only by the biasing force of the spring arm 19, the locking hub 17 is further rotated until the detent roller 21 is fully engaged in the next detent recess 18. But this is also the Einerminutenscheibe 16 further rotated by a digit exactly positioned.
    By the step switching device also formed by the drive shaft 4 Nachspannachse a Nachspannwerks is rotatably driven in minute increments and tensioned a memory coil spring 23 of the restraint. The accumulator spiral spring 23, the drive shaft 4 is arranged enclosing. With its inner end, the spiral storage spring 23 is fixedly connected to a hub of a second Kleinbodenrades 24 which is freely rotatably supported by means of the hub on the drive shaft 4.
    By the second Kleinbodenrad 24, a fourth shaft 25 is continuously rotatably driven, on which a second wheel 26 is arranged. The second wheel 26 is engaged with a pinion of an escape wheel 27 for inhibiting the oscillating system of the timepiece.
    At one end portion of the fourth shaft 25, an eccentric 28 is arranged, which is encompassed by a fork 29 at the free end of a first arm 30 of a three-armed lever 31. The three-armed lever 31 is pivotally mounted about a parallel to the fourth shaft 25 lever axis 32. Upon rotation of the fourth shaft 25, the first arm 30 is pivoted by the eccentric 28 between a first end position and a second end position.
    At the free end of a second arm 33 of the lever 31 is formed as a first pallet 34 formed first locking element, while at the free end of a third arm 35 designed as a second pallet 36 second locking element is arranged.
    In the first end position of the lever 31, the first pallet 34 is pivoted into the tooth circulation area of a tooth 37 of the single-toothed control drive 7, which is arranged on the first shaft 6.
    In the second end position of the lever 31, the first pallet 34 is outside the tooth circulation area of the tooth 37, while the second pallet 36 is pivoted into the tooth circulation area of a tooth 25 of a second single-toothed wheel 39 which is parallel to the fourth shaft 25 fifth shaft 40 is arranged.
    In the first end position, the second pallet 36 is outside the tooth circulation area of the tooth 41 of the second wheel 39.
    The fifth shaft 40 carries a second drive wheel which is rotatably driven by the first small-bottom wheel 3.
    In the first end position of the lever 31 is prevented by the abutment of the tooth 37 on the first pallet 34 of the single-toothed control drive 7 at a rotation.
    Thus, via the first shaft 6 and the display control drive 5 and the first Kleinbodenrad 3 is blocked, so that the drive spring of the barrel 1, the first Kleinbodenrad 3 can not drive to a tensioning of the memory coil spring 23.
    About the acted upon by the memory coil spring 23 second Kleinbodenrad 24 but controlled by the oscillating system is a continuous rotary drive of the fourth shaft 25 and with it the eccentric 28th
    As a result, the control of the tensioning device is performed by the oscillating system of the clock.
    In this case, the eccentric 28 pivots the lever 31 from its first end position in the direction of its second end position.
    As a result, the first pallet 34 is moved out of the tooth circulation area of the tooth 37 and the single-toothed control drive 7 is released.
    At the same time, the second pallet 36 is moved into the tooth circulation area of the tooth 41.
    Under the tension of the drive spring of the barrel 1, there is now a short rotation of the drive shaft and with it the first low-order wheel third
    About the second drive while the fifth shaft 40 is rotated so far until the tooth 41 comes to rest on the second pallet 36.
    The lever 31 is now pivoted by the eccentric 28 from its second end position to its first end position, the first pallet 34 being moved out into the tooth circulation area of the tooth 37 and the second pallet 36 being moved out of the tooth circulation area of the tooth 41.
    Under the tension of the drive spring of the barrel 1, there is a rotary drive of the drive axle and the first low-order wheel 3 and the one-toothed Steuerviebs 7 and the second wheel 39 until the tooth 37 of the one-toothed timing drive 7 abuts against the first pallet 34 and another rotation of the single-toothed control drive 7 and blocked with him the first low-level gear 3.
    As described above, the Einerminutenscheibe 16 is further rotated by one digit by the rotation of the single-toothed timing drive 7 by one revolution.
    By the rotation of the first low-order wheel 3, there is a cycle of a re-tensioning of the accumulator coil spring 23, through which the escapement and the oscillating system are continuously driven via the second wheel 26.
    On the fifth shaft 40, a damping wheel 42 is arranged parallel to the second wheel 39, which engages in a pinion 43 on a Flügelradachse 44, which carries a Windflügelrad 45.
    Since during the Nachspannbewegung also the Windflügelrad 45 is driven, the Nachspannbewegung is damped, so that it does not come to a hard abutment of the teeth 37 and 41 on the pallets 34 and 36 and thus to rebound movements.
