    Description: The invention relates to a step-by-step drive of a watch with a one-wheel that can be driven by a clockwork in ten steps of one revolution per ten minutes around a one-axis of rotation and is firmly connected to a one-display element, with one of the one-wheel at ten Steps per ten minutes around a tens axis in a direction of rotation, which can be driven by means of a tens indicator wheel, by means of which a tens display element can be rotated at an increment of one rotation at six increments per hour, with an hour display element which can be driven by the one-wheel or the tens selector wheel at an hourly step per hour about an hour axis.
    In such a stepping device, a jerky further sharing of a display member of a clock at hourly intervals is known. The energy required for the hourly, jerky movement of the display element is stored by a spring device during the passage of an hour. The spring device receives this energy from the clockwork via a first gear.
    The object of the invention is to provide a stepper drive of a clock of the type mentioned, which has a simple structure to support the ten steps of the tens display and at an hour change both the hourly increment of the hour display and the tens of the tens display.
    This object is achieved according to the invention in that a charging curve which is rotatable about the tens of rotation axis is connected coaxially to the tens switching wheel, which spirals from an angle of radially smallest diameter to an area of radially largest diameter by an angle> 260 ° and <360 ° the advancing direction is increasing and the point of radially smallest diameter and the area of radially largest diameter are connected to each other by a side that slopes inclined against the advancing direction at an angle of rotation of the tens switching wheel of <100 °, with a switching spring lying radially on the charging curve, which is caused by the rotation the charging curve can be tensioned during the first nine steps of the one-wheeler and slides radially inwards along the charging curve during the tenth step of the one.
    Preferably, the charging curve by an angle> 324 ° and <360 ° rising spirally and the points of radially smallest diameter and radially largest diameter by the inclined side opposite the advancing direction falling at an angle of rotation of <36 °.
    By switching the tens display and the hour display organ in addition to the one display organ, an increased torque for switching all display elements is required. Since this increased torque is also made available in the individual circuits of the single display element, unnecessary energy would be introduced which would require a larger size. Due to the charging curve, the excess energy from nine circuits of the single display element is used to open the switching spring. If the switch spring is located on the largest diameter of the charging curve, in which the unit indicator shows the number nine, then the switching spring is just about to press the sloping side of the charging curve. With the start of the switching of the single display organ from nine to zero, the switching spring moves to the falling side of the charging curve. The shift spring thus begins to support the switching of the tens display element and, when the hour changes, also the switching of the hour display element.
    The consequence of this support is that less clock must be provided by the clockwork and thus by the barrel, so that the tens display element and the hour display element can be switched. The torque door of the individual circuits of the single display element need only be increased to a small extent.
    In a simple embodiment, the switching spring can be a spring arm with its one end region that is stationary and that is in direct or indirect contact with the free end region on the charging curve.
    For indirect contact of the switching spring on the charging curve, a multi-armed tens switch lever mounted pivotably about a switching lever axis can be acted upon by the switching spring on a switching spring arm and be in contact with the end region of a charging arm on the charging curve.
    The single display element can be a single disc with the numbers 0 to 9 radially rotating and / or the tens display element can be a tens disc with the numbers 0 to 5 rotating radially and / or the hour display element can be an hour disc with the numbers 0 to 11 rotating radially or 1 to 12.
    Instead of a single disc, the one display element can also be a single hand, instead of the tens disc, the tens display element can also be a tens hand and instead of the hour disc, the hour display element can also be an hour hand.
    If the axes of rotation of the single display element and the tens display element are arranged coaxially to one another, this leads to a reduction in the installation space required.
    In a simple design, a tens shift finger can be firmly connected to the tens indicator wheel with the tens selector wheel, which, at a radial distance from the tens axis of rotation, has a parallel pin parallel to the tens axis of rotation, which can be engaged in six radial slots of a star wheel, which are evenly distributed over the circumference, by which Tens display element can be driven at six increments of ten per hour rotatable about the axis of rotation.
    CH 714 520 A2 [0014] If the display elements for correction or for setting by means of a crown can be adjusted manually in both directions of rotation, then a pivoting lever can be moved from a manually actuated crown shaft, through which the single disk, the tens disk and the hour disk can be rotated, between a pivoting position and a pivoting-in position can be pivoted about a pivoting axis parallel to the axis of rotation of ten, the pivoting lever in its pivoting position being disengaged from a pivoting arm of the tens shift lever and wherein the ten-shift lever is pivoted out of engagement with the pivoting lever by the movement of the pivoting lever from the pivoting position into the pivoting position out of engagement with the loading curve is acted upon.
    Thus, when the display elements are reset, an unwanted collision of the pivoting lever, in particular with the sloping side of the charging curve, cannot occur.
    In a simple embodiment, a continuous pivoting movement can be produced if the pivoting arm has a pivoting curve, along which a pivoting nose of the pivoting lever slides during the pivoting movement from the pivoting position into the pivoting position and acts on the tens shift lever so as to be pivotable out of engagement with the charging curve.
    To fix the swing-out arm in the swivel-out position, the swivel-out nose in the swivel-out position of the swivel-out lever can simply be snapped into a latching recess at one end of the swivel-out curve of the swivel-out arm until the process of correcting the display elements is ended and the elevator shaft is moved back into its normal position ,
    An embodiment of the invention is shown in the drawing and is described in more detail below. It shows:
    Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 Fig. 7 is a perspective view of a stepper drive with indicator disks a view of functionally relevant areas of the stepper drive according to Fig. 1 is a plan view of the stepper mechanism according to Fig. 1 with the one and ten disks 1 in a first switch position a top view of the step switch according to FIG. 1 in a second switch position a top view of the step switch according to FIG. 1 in a third switch position an enlarged view of a charging plate of the step switch according to FIG. 1.
    A drive switching wheel 1 is connected via an axis 2 to a 20-tooth intermediate gear 3 and is rotated by a stepping mechanism, not shown, once per minute through an angle of 72 °. This turns the idler gear 3 by four teeth per minute.
    The intermediate wheel 3 engages in a one-wheel 4, which has forty teeth and is thus rotated once per minute by an angle of 36 °. The one-wheel 4 thus rotates exactly once in ten minutes.
    The one-wheel 4 is connected to a radially encircling zero-to-nine bearing washer 5 concentrically connected and rotatably supported on a tens shaft 6.
    On the tens shaft 6, a radially encircling numerals from zero to five bearing tens washer 8 is arranged.
    The one-wheel 4 engages in a forty-toothed ten-wheel 9, which makes ten steps in ten minutes, each with an angle of rotation of 36 ° about the ten-axis of rotation 7.
    With the tens switching wheel 9, a radial tens shift finger 10 is fixedly connected, which has at a radial distance from the tens wheel axis 7 a parallel to the tens axis of rotation 7 indexing pin 27.
    A charging disc 11 is coaxially connected to the ten-gear 9 rotating test. The charging disc 11 has on its radially circumferential contour a charging curve 12 which has a spiral region 13 which extends in a spiral manner over 335 ° and an inclined side 14, the inclined side 14 being the point 15 of the smallest radial diameter with the region 16 of the largest diameter of the spiral region 13 connects to one another.
    The charging disc 11 with the charging curve is shown enlarged in FIG. 7.
    In this embodiment, the charging disc 11, the charging curve 12 is divided into ten angular ranges, of which starting from the point 15 of radially smallest diameter to a region 16 of radially largest diameter in the first nine angular ranges 35 in its first angular range part 36, the charging curve 12 extends concentrically to the axis of rotation 7 in order then to rise in a second angular range part 37 such that it reaches the next following angular range 35, increasing by a certain radial distance 38. In the first angular range part 36 'of the tenth angular range 35', the charging curve 12 also extends concentrically to the toe 3
    CH 714 520 A2 axis of rotation 7 in order then to be traced back to point 15 of smallest diameter in a second angular range part 37 'via an inclined side 14.
    A three-armed ten-armed lever 17, which is pivotably mounted about a shift lever axis 18 parallel to the ten-axis of rotation 7, has a switching spring arm 19, a charging arm 20 and a swiveling arm 21.
    Through the free end region of the switching spring arm 19, the cantilevered end region of a switching spring 22 designed as a spring arm can be acted upon, the other end region of which is arranged in a stationary manner.
    The charging arm 20 has at its free end a scanning tip 23 with which it is in radial contact with the charging curve 12 during normal operation of the watch.
    Through the stepping mechanism, the ten-wheel 9 and with it the charging disc 11 is rotatably driven so that the charging curve 12 moves from the point 15 in nine steps along the scanning tip 23. The unit disk 5 is thus in its position indicating the number nine (FIG. 4).
    Switches the unit disk 5 in the following tenth step to the following zero, at the same time by means of the ten-gear wheel 9 firmly connected, radially directed ten-shift finger 10 a six evenly spaced radial slots 26 having star wheel 25 by one of six Turned ten steps per hour by a progressive pin 27 extending at a radial distance from the tens axis of rotation 7 parallel to the tens axis of rotation 7 engages in one of the radial slots 26 and rotates the star wheel 25 further. The tens disk 8, which is connected to the star wheel 25 in a rotational test, is thus also moved by a ten step.
    Show one's disc 5 and tens disc 8 just fifty-nine minutes, then with the next step switching of the one disc 5 also an hour disc, not shown, is advanced.
    During the first nine steps of the charging curve, the scanning tip 23 is moved radially outward and the tens switch 17 is pivoted such that it stretches the switching spring 22 in nine steps via the switching spring arm 19.
    In the tenth step of the loading curve 12, the scanning tip 23 arrives in the region of the falling side 14 of the charging curve 12, whereby under the force of the switching spring 22 of the tens lever 17 with the scanning tip 23, an additional force on the charging curve 12 and thus also exerts on the ten-shift wheel 9 and the ten-shift finger 10, so that the latter switches the star wheel 25 with the tens disk 8 with an additional torque and, at a full hour, also the hour disk by one step.
    A crown shaft 28 is manually displaceable in its longitudinal direction between a normal position and an actuating position. In the set position, the ones disk 5, the tens disk 8 and the hour disk can be adjusted for correction in both directions of rotation. This would also lead to a twisting of the charging disc 11, which would result in stiffness and possibly a blockage of the scanning tip 23 on the radially sloping side 14 when rotating against the normal indexing direction.
    In order to prevent this, a pivoting lever 29 can be pivoted from the crown shaft 28 about a pivoting axis 30 parallel to the axis of rotation 7 between a pivoting position and a pivoting position.
    In its swiveled-in position (FIGS. 4 and 5), the swivel-out lever 29 is disengaged from the swivel-out arm 21 of the tens switch lever 17.
    If the pivoting lever 29 is pivoted by the crown shaft 28 from its pivoting position into its pivoting position, it comes into contact with a pivoting nose 31 on a pivoting curve 32 of the pivoting arm 21 and slides along the pivoting curve 32 upon further pivoting of the pivoting lever 29, whereby he Swinging arm 21 and with it the ten-shift lever 17 pivoted so that the scanning tip 23 moves radially away from the loading curve 12.
    In the maximally lifted position of the scanning tip 23 from the charging curve 12, the swivel nose 31 reaches a detent depression 33 at one end of the swivel curve 32 and engages there. The ten-shift lever 17 is thus fixed in a position lifted off the charging curve 12 with its scanning tip 23 (FIG. 6) until the crown shaft 28 is moved back into its normal position.
