Description: The invention relates to a shifting device of a watch, having a drive wheel which can be driven rotatably about a drive wheel axis with a certain number of drive wheel steps per revolution, with a radially directed shift finger arranged on the drive wheel and rotatable with the drive wheel about the drive axis of rotation. the once per revolution of the drive wheel reaches a shift position and engages in the following drive wheel step of the drive wheel in a parallel to the drive axis axis Schaltradachse rotatable ratchet wheel and the indexing wheel to a Schaltradteilung and with a manual indexing device through which the ratchet is manually fortschaltbar to a Schaltradteilung ,
Such Fortschalteinrichtungen a clock serve, for example. for rotatably driving a monthly ring of a calendar with one step per month. If the shift finger is e.g. early by a shock already in the area of the teeth of the ratchet wheel, so would be anticipated in a manual indexing of the ratchet automatic indexing, which would require a correction.
The object of the invention is therefore to provide a shunting device of a clock of the type mentioned, which reduces this risk of erroneous switching, is simple in construction, has a small size.
This object is achieved according to the invention that the shift finger in the indexing position relative to the drive wheel to a lot of at least one step of the switching wheel against a spring force of the ratchet wheel is deflectable vorstebar.
Once per revolution of the drive wheel, the indexing position is reached. In the following step of the drive wheel, the shift finger is still safely out of the circulation area of the teeth of the ratchet held, even if the shift finger should have been preceded by external influences such as shock or shock within his ability to move the lots.
If in the indexing manually a shift of the indexing wheel by the indexing means, so there is no co-rotation of the shift finger and thus no anticipation of a continuation by the drive wheel for the lack of engagement of the shift finger in the circulation area of the teeth of the ratchet wheel.
In a simple embodiment, a parallel to the drive axis loose pin can be arranged on the shift finger, which projects into a concentric groove of the drive wheel, whose length corresponds to the lots.
The spring force against which the shift finger is vorstebar deflected, is generated in a simple manner that on the shift finger a cantilevered spring arm is arranged with its one end, with its other free end portion upon reaching the indexing position to a stationary stop comes into contact and locked in the following drive wheel step under deflection of the stationary stop.
Space saving while the spring arm can extend around the drive axis of rotation at a distance radially encircling and have to latch at its end a radially outwardly or inwardly outstanding locking lug.
The indexing device can be used in a clock always when an element is weiterzuschalten by a shift finger and the need exists that the shift finger as long as possible to be kept away from the teeth of the element to be switched.
A particularly advantageous application is that the drive wheel is a monthly gear of a date circuit of a calendar of a clock, wherein the monthly gear is rotatably driven in daily steps of 31 daily positions per revolution.
It can be rotatably driven by the Monatsschaltrad a drive train from which a monthly ring of the calendar of the clock with one step per month is rotatably driven.
In the inventive training, the shift finger against the Monatsschaltrad can still rotate forward so that during the last days of the month, the manual indexing device is not blocked when the shift finger would possibly already be in the teeth of the monthly gear. Depending on the geometric conditions, this could otherwise be the case on the thirtieth or even the twenty-ninth day of the month. In the worst case, even earlier, provided that the shift finger has hurried through an unfavorable blow to the area of the teeth of the monthly gear wheel. Whenever the shift finger is in this range, you would anticipate the automatic monthly shift by the clock at the end of a monthly correction by the manual indexing device. An independent monthly correction would then no longer be executed. Although nothing would be destroyed, a user would have to correct the month if necessary.
These problems are largely eliminated by the invention.
The monthly ring may have a ring-shaped monthly curve in a simple training, which represents the twelve months of a year and depending on the number of days of a month has a greater or lesser distance to the axis of rotation of the month ring, wherein on the monthly curve a button for detecting the Month lengths in plant is.
To represent the month names can be arranged on the monthly ring radially circumferentially uniformly distributed the twelve month names of a year, the month to be displayed each month can be visible through a window in a dial.
An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it

The illustrated date circuit of a calendar of a timepiece has a calendar drive wheel 1 which, with one revolution per twenty-four hours, e.g. is rotatably driven by a clockwork. On the calendar drive wheel I, a drive arm 2 is arranged, which rotates with the calendar drive wheel 1 about the axis of rotation of the Kalenderantriebsrads 1 while once per revolution with a Schalthebelarm 3 pivotable about a pivot axis 5 shift lever 4 engages and the shift lever 4 against the force of a first spring 6 from a normal position in which the shift lever is in abutment against a stop 7, pivoted in a pivot position.
On a ratchet arm 8 of the shift lever 4, a pawl 9 is pivotally articulated about a pawl axis 10, which has a pawl tooth 11 which is directed with its pawl tip 12 radially to a Datumradachse 13 of a Daterades 14 and by a second spring 15 for Datumradachse 13th is energized.
The date wheel 14 has thirty-one teeth, which corresponds to the thirty-one day positions of the date wheel 14.
By a pivoting movement of the shift lever 4 from the normal position in the pivot position, the pawl 9 is always and regardless of the month length moves a distance that corresponds to two divisions of the date wheel 14 to the Datumradachse 13.
At a first end portion 33 of a date lever axis 13 parallel to the Datumradachse 13 pivotable two-armed Datehebels 17 a Datekulisse 18 is arranged, which extends radially outside the top circle of the Daterades 14 along a portion of the date wheel 14. In the normal position of the shift lever 4, the pawl tooth II is radially in contact with the date slide 18 and can not engage in the tooth spaces of the date wheel 14.
When the shift lever 4 moves from the normal position in the pivot position, the pawl tooth 11 first slides counterclockwise on the date slide 18 by a pitch of the date wheel 14, then in the circumferential direction of the date slide 18 at the date gate end 19 radially into a tooth gap of the date wheel 14 to move in and to move a second pitch counterclockwise. In this case, the date wheel 14 is further rotated by a tooth pitch counterclockwise.
A monthly ring 20 is rotatably disposed about a rotation axis 21, which coincides in the present case with the pivot axis 5 of the shift lever 4. The inner periphery of the monthly ring 20 forms a monthly curve 27, which represents the twelve months of a year and depending on the number of days of a month (30 or 31 days) has a greater or lesser distance from the axis of rotation 21 of the month ring 20. A long month has a greater distance and a short month a smaller distance from the rotation axis 21 of the month ring 20.
To a parallel to the first axis of rotation 21 second axis of rotation 22 is a two-armed second date lever 23 pivotally, which has a button 25 at the free end of its first arm 24, by a second date lever 24 acting third spring 26 in contact with the monthly curve 27 is held.
The second arm 28 of the second date lever 23 is hinged at its free end to the first end 30 of a third date lever 29. The second end 31 of the third date lever 29 is hinged to the second end portion 32 of the first date lever 17.
The third date lever 29 has in its central region a radially directed to the Datumradachse 13 ramp 34 which projects radially into the circulation area of a date wheel 14 arranged on the cam 35 depending on the position of the probe 25 on the monthly curve 27 or radially outside of the Circumferential area of the cam 35 is located. In the case of a short month of the month ring 20 scanned by the button 25, the ramp 34 protrudes in the circulation area of the cam 35 and at a long month of the month ring 20 scanned by the button 25 the ramp 34 is outside the circulation area of the cam 35.
The cam 35 is arranged on the date wheel 14 in such a way that it reaches the area of the ramp 34 in a twenty-ninth day position of the date wheel 14.
If a long month with thirty-one days is scanned by the button 25, there is no contact between the ramp 34 and the cam 35.
For a short month of thirty days, ramp 34 is moved by the second date lever 23 and the third date lever 29 into the circulation area of cam 35 and raises upon ramping of cam 35 onto ramp 34 at the transition of date wheel 14 from the twenty-ninth Day position on the thirtieth day position the third date lever 29 radially away from the date wheel 14 away. This movement is transmitted via the second end 31 of the third date lever 29 on the first date lever 17 and pivots this under the application of force to a fourth spring 36 in a clockwise direction by a daily position.
Thus, the pawl tooth 11 falls radially at the date gate end 19 in a tooth space of the date wheel 14 a. Now, if a pivoting of the shift lever 4, the pawl 9 rotates the date wheel 14 not only a day position but two day positions, ie from the thirtieth day position skipping the einunddreis-siges day position directly into the first daily position of the following month.
The date wheel 14 drives a rotatable about a drive axis 38 monthly gear 37, which has the same number of teeth as the date wheel 14. On the Monatsschaltrad 37, a radially directed shift finger 39 is arranged, which is rotatable with its one end about the drive axis of rotation 38 and with its radially directed switching tip 40 bildendendem the other end radially beyond the top circle of the Monatsschaltrades 37.
The shift finger 39 reaches once per revolution of the Monatsschaltrades 37 a shifting position and engages with its switching tip 40 in a ratchet wheel 41 which is rotatable about a parallel to the drive axis 38 ratchet wheel 42 and star-like twelve teeth 43, the twelve months of a Year correspond.
On the shift finger 39 a parallel to the ratchet wheel 42 loose pin 44 is arranged, which projects into a concentric groove 45 of the ratchet whose length corresponds to a ticket that extends over two daily positions of the date wheel 14 and thus also of the monthly gear. In normal operation, the loose pin 44 abuts against the rear end of the groove 45 in the direction of rotation of the monthly shift wheel 37, so that the monthly shift wheel 37 carries the shift finger 39.
On the shift finger 39 is a freewheeling concentrically encircling, radially resilient spring arm 46 is arranged with its one end, which has a locking pin formed as a locking projection 47 at its free end, which projects with play through a concentric slot 50 in the monthly gear 37. In the circulation area of the locking projection 47, a pin-like stopper 48 is fixedly arranged on a circuit board 49.
Once per revolution of Monatsschaltrades 37 a forward position is reached at one end of the month, in which the locking projection 47 comes into abutment against the stop 48. In the following step of the monthly gear 37, the spring arm 46 is first deflected radially inwardly, wherein the shift finger 39 is briefly retarded in its rotational movement relative to the monthly gear 37. As a result, the switching tip 40 of the shift finger 39 is kept out of the circulation range of the teeth 43 of the switching wheel 41, the shift finger 39 should have been pre-aligned by external influences such as shock or shock within its ability to move in the groove 45. In the following step of the monthly gear 37 of the locking projection 47 engages under the resilient deflection of the spring arm 46 radially inwardly the stop 48th
Except by the shift finger 39, the ratchet 41 can be indexed by a manual indexing device 51 by a shift wheel division.
The progression position corresponds to the penultimate day of the respective month. In this indexing position, the switching tip 40 of the shift finger 39 is securely held by the spring arm 46 and the locking lug 39 from the circulation area of the teeth 43 of the switching wheel 41. If, on this penultimate day of the month, manual indexing of the indexing wheel 41 by the indexing device 51 occurs, lack of engagement of the indexing point 40 in the circulating area of the teeth 43 of the indexing wheel 41 will not cause the indexing finger 39 to rotate and thus not anticipate progression through the monthly indexing wheel 37 ,
In the shift position on the thirty-first day of a month, there is the possibility of anticipating the indexing of the switching wheel 41 by the Monatsschaltrad 37 by a manual indexing means of the advancing device 51st
The switching wheel 41 is fixedly connected to a coaxial indexing wheel 52 which engages in a pinion 53. The pinion 53 is in turn connected coaxially with a monthly ring gear 54, which engages in a radially encircling ring gear 55 of the month ring 20.
When the indexing wheel 41 is indexed by one pitch, the monthly ring 20 is further rotated by one month division via the indexing wheel 52, the pinion 53 and the monthly ring gear 54.
