    Description: The invention relates to a mechanical annual calendar of a watch, with a rocker switch which can be pivoted once every twenty-four hours about a rocker pivot axis and on which a ratchet arm is pivotably pivoted about a ratchet axis at a radial distance from the rocker axis a shift pawl arranged on the ratchet arm at a distance from the ratchet axis, which engages under spring tension in the teeth of a thirty-one or a multiple of thirty-one teeth date wheel and by which the date wheel by one or two days corresponds to one or two days when the rocker switch pivots Tooth pitches can be rotated in a certain direction of rotation, a date display being drivable by the date wheel, with a month end disk connected concentrically to the date wheel and having a radially circumferential circular contour on which a probe tip is one by two te pivot axis of pivotably mounted probe arm under resilient pretension is in contact, the pivoting movement of the probe arm being able to switch a device determining the pivoting angle of the rocker switch for advancing the date wheel by one or two days.
    The object of the invention is to provide a mechanical annual calendar of a clock of the type mentioned, which has a few simple components.
    This object is achieved in that the circular contour of the month end disc has a radially inward scanning gap that extends in the circumferential direction with a constant depth over two tooth pitches of the date wheel and then ramps up to the circular contour against the specific direction of rotation of the date wheel.
    Through this training, the components of the mechanical annual calendar are simple, which makes these components easy to manufacture. This ease of manufacture leads to a high degree of freedom from defects in the components and thus to a high level of functional reliability of the mechanical annual calendar.
    On the thirty-first of a month, the probe tip of the probe arm is located on the ramp-like increase in the scanning gap of the month end plate, so that a moment directed against the specific direction of rotation of the date wheel firmly connected to the month end plate acts on the month end plate. In order to prevent the date wheel from turning back, a return lock spring can block a rotation of the date wheel against the specific direction of rotation of the date wheel.
    A structure with easy to manufacture, functionally reliable components is achieved in that the advancement of the date wheel of one or two days determining device has a monthly scanning disc that can be rotated in twelve steps with one revolution per year and whose radially revolving monthly contour depends on long months and short months has a larger diameter and a smaller diameter, wherein a button of the rocker switch is acted upon by a spring force against the monthly contour and can be lifted off the monthly contour once every twenty-four hours.
    The feeler arm can have a monthly pawl which can be engaged in the tooth gaps of a month drive concentrically connected to the monthly sensing disc, having twelve teeth.
    When the probe tip of the probe arm falls into the scanning gap, the tooth of the monthly drive to be switched is jumped over and when the probe tip slides up on the ramp-like increase in the sampling gap, the monthly drive is switched by one tooth pitch.
    Preferably, a monthly catch resiliently engages inward in a tooth gap of the monthly shoot and switches the missing path after reaching the monthly shoot until the correct new target position of the monthly shoot is reached.
    The rocker switch can have a feeler cam which is in contact with a stop of the probe arm when the probe tip is in contact with the circular contour of the month end disk, whereby the button is prevented from radially plunging into the areas of short months of smaller diameter of the month contour of the month probe disk, wherein when the probe tip is immersed in the scanning gap it is out of contact with the stop and the key can be radially immersed in the areas of short months of smaller diameter of the monthly contour of the monthly scanning disk.
    As a result, the button of the rocker switch can only be immersed in the areas of short months, even if the probe tip is immersed in the scanning gap.
    An embodiment of the invention is shown in the drawing and is described in more detail below. Show it

    From a clockwork, not shown, an hour wheel 1 is rotatably driven with one revolution per twelve hours in a direction of rotation «a» and drives a 24-hour wheel 2 with one revolution per twenty-four hours. The 24-hour wheel 2 has an axially protruding pin 3 which, when the 24-hour wheel 2 rotates, takes along a shift finger 4 which extends approximately radially to the axis of rotation of the 24-hour wheel 2 and is arranged on the 24-hour wheel 2.
    Once a day, this switching finger 4 switches the date on. The switching of the date begins when the shift finger 4 touches a shift arm 25 of a shift rocker 5 pivotable about a rocker pivot axis 28 parallel to the pivot axis of the 24-hour wheel 2.
    Turns the hour wheel 1 against the direction of rotation «a» and thus drives the 24-hour wheel 2, the part of the shift finger 4 acting on the shift arm 25 can deflect resiliently and do not pivot the rocker switch 5 with this wrong direction of rotation.
    After the switching finger 4 and the switching arm 25 of the rocker switch 5 have touched, the rocker switch 5 is pivoted out of its basic position against the force of a prestressed rocker switch spring 6. The rocker switch 5 has a button 26 at a radial distance from the rocker pivot axis 28. The rocker switch spring 6 always presses the rocker switch 5 against the radially circumferential monthly contour 29 of a monthly scanning disk 7 which can be rotated about a monthly rotary axis 31 parallel to the rocker pivot axis 28. The radially circumferential monthly contour 29 of the monthly scanning disk 7, which can be rotated clockwise in twelve steps per year, has a large circumferential radial circumference for the long months of thirty-one days and a small diameter 27 for the short months of thirty days.
    On the rocker switch 5 is arranged at a radial distance from the rocker pivot axis 28 about a parallel to this rocker pivot axis 28 pawl axis 32 pivotable pawl arm 33 which has a pawl 8 at its one free end.
    By a preloaded pawl spring 9, the pawl arm 33 with its pawl 8 engaging in the teeth of a thirty-one tooth date wheel 10 engaging.
    During the date switching, the pawl 8 is pulled tangentially to the date wheel 10 by the rocker switch 5. Thus, the pawl 8 pulls on the toothing of the date wheel 10 and sets it in a certain direction of rotation, namely counterclockwise in rotary motion.
    This rotary movement also drives a drive train from the date wheel 10 to a thirty-one tooth display wheel 12 forming intermediate wheels 11 in rotary motion.
    Also in a tooth gap of the date wheel 10 resiliently engaging and a rotation counter to the drive direction of the date wheel 10 locking return spring 13 and a tooth gap of the indicator wheel 12 resiliently engaging indicator wheel 14 are raised to then re-engage in an adjacent tooth gap.
    On the display wheel 12, a pointer, not shown, is arranged, which moves along a date scale, which is also not shown, and has thirty-one divisions.
    After completion of the date circuit, the switching arm 25 falls again from the shift finger 4. The spring-loaded pawl 8 engages behind the next tooth of the date wheel 10, which is then again drawn tangentially to the date wheel 10 at the next date switching.
    The monthly scanning disc 7 limits the path of the rocker switch 5 over the entire month, so that only one tooth and thus only one day is switched every twenty-four hours.
    Concentric to the date wheel 10 is firmly connected to the date wheel 10 a month end disk 16, which has a radially circumferential circular contour 34 on which a probe tip 17 of a probe arm 18 pivotably mounted about a second pivot axis 35 rests under resilient bias.
    At the position of the days of the month from the thirtieth of a month, the circular contour 34 has a radially inward scanning gap 15 which, contrary to the specific direction of rotation of the date wheel 10, initially extends over two divisions corresponding to two days with constant depth and then with one ramp-like rise 30 to the circular contour 34 to rise again.
    On the thirtieth day of each month, the scanning gap 15 of the month end disk 16 is under the probe tip 17 of the probe arm 18 (Fig. 2). The spring force of a pretensioned stylus spring 19 ensures that the stylus arm 18 is pressed into the scanning gap 15 of the month end disk 16. A monthly drive 22 having twelve teeth is concentrically connected to the monthly scanning disk 7.
    CH 713 307 A2 Due to the dropping of the probe tip 17 into the scanning gap 15, a month switching pawl 20 of the probe arm 18 engaging in the monthly drive 22 has moved one tooth pitch further. The month pawl 20 is always pressed into the teeth of the month drive 22 by a spring arm 21.
    On the thirty-first of a month, the probe tip 17 of the probe arm 18 is on the ramp-like rise 30 of the sampling gap 15 of the month end disk 16 (FIG. 3). This creates a restoring moment for the date wheel 10. The anti-return spring 13 prevents the month end disk 16 from turning back against the specific direction of rotation.
    When switching from the thirtieth to the thirty-first day of the month, the free travel of the monthly pawl 20 to a tooth 23 of the monthly drive 22 was reduced. When the date wheel 10 is switched during the night from the thirty-first day to the first day of the following month, the date wheel 10 rotates so that the probe arm 18 is raised even further. The monthly pawl 20 pushes on the tooth 23 of the monthly drive 22. The monthly drive 22 is thus set in rotation. A monthly detent 24 engaging radially resiliently in a tooth gap of the monthly shoot 22 is thereby lifted and completes the missing path of the monthly shoot 22. It was switched on for a month. While the month is being switched on, the rocker switch 5 does not rest resiliently on the monthly contour 29 of the monthly scanning disk 7, since it is raised to switch the date. Thus, only the spring force of the monthly catch 24 has to be overcome for the monthly switching.
    From the first to the twenty-ninth of a short month, the rocker switch 5 can always reach behind only one tooth of the date wheel 10 and thus also advance only one tooth (FIG. 4). This is because the stylus tip 17 of the stylus arm 18 is in contact with the circular contour 34 of the month-end disk 16. The rocker switch 5 would have the option of springing up with its button 26 onto the small diameter 27 of the monthly contour 29 of the monthly scanning disk 7. This is prevented in that a sensing cam 36 of the rocker switch 5 comes to rest against a stop 37 of the sensing arm 18. This means that the button 26 cannot move onto the small diameter 27 of the monthly contour 29.
    On the thirtieth of a short month, the probe tip 17 of the probe arm 18 falls into the scanning gap 15 of the month end disk 16 (FIG. 5). Since the probe tip 17 of the probe arm 18 can now drop lower, the rocker switch 5 can now fall with its key 26 onto the small diameter 27 of the monthly contour 29 of the monthly scanning disk 7. The pawl 8 can now not only jump behind a tooth of the date wheel 10, but two teeth. This time the pawl 8 can turn the date wheel 10 by two tooth pitches and thus switch from the thirtieth day of a month to the first day of a month.
