Definitions

  • the present invention relates to a date mechanism with a large date comprising two superposed calendar rings, respectively upper and lower, one of which carries fifteen successive markings of a cycle of 31 positions, while the other carries the other sixteen markings.
  • Counter metering and cyclic display devices used in calendar timepieces for displaying the date are already known.
  • the analog display of the date is conventionally made using a date ring which has 31 sectors bearing the markings from 1 to 31.
  • a device has the disadvantage of not offering, for each sector, a field whose size corresponds to a 31 th of the circumference of the ring.
  • the dimensions of this field are insufficient to allow an easily readable date display.
  • the need for a device to display a "large date" on a field much wider than a 31 th circumference has been felt.
  • the Brandi patent teaches a date mechanism mainly comprising a date ring greater than sixteen sectors, superimposed on a lower ring having seventeen sectors.
  • the upper ring covers fifteen of its sectors markings "17" to "31” while the last sector is equipped with a window.
  • the lower ring has on sixteen of its sectors the markings "1" to "16", while the last sector is free of marking.
  • the inner circumference of the two rings has teeth, a location for the upper ring and a location for the lower ring being toothless.
  • a date training finger typically making a turn every twenty-four hours, drives the calendar rings in a conventional manner, by action on their teeth.
  • the position of the driving finger relative to the teeth of the rings is such that when a ring has its free position (aperture for the upper ring and unmarked sector for the lower ring) at the display location of the shows, the drive finger is in front of the tooth-free position of the concerned ring.
  • the Brandi patent provides a date mechanism for a timepiece which advantageously makes it possible to give the date indication a large format, substantially twice that of a conventional date mechanism.
  • This date mechanism is animated by a training finger which makes a turn every twenty-four hours and which drives the date rings by action on their teeth.
  • a correction device that would quickly change the indication provided by the date mechanism.
  • two jumper locking devices act respectively on the teeth of the upper ring and on the teeth of the lower ring. But, considering that a place of the teeth of each of these rings is toothless, these jumpers must be double top and support between the tips of three successive teeth.
  • jumpers must therefore be large and are therefore bulky.
  • the mechanical characteristics of the retention exerted by the jumpers on the two date rings are different depending on whether the missing tooth is in first, second or third position vis-à-vis said jumpers. We must therefore find a compromise that ensures that, whatever the position of the missing tooth, the jumper ensures a satisfactory positioning of the ring concerned. Such jumpers are therefore difficult to develop.
  • the object of the present invention is to overcome the aforementioned drawbacks as well as others by providing a date mechanism making it possible to give the date indication a large format, this mechanism comprising two superposed rings, respectively upper and lower, one of which carries fifteen successive markings of a cycle of 31 positions, while the other carries the other sixteen markings, a rapid correction device for quickly changing the indication provided by the date mechanism.
  • Another object of the present invention is to provide a date mechanism of the aforementioned kind comprising a jumper device for securing the two rings.
  • the present invention relates to a date mechanism for a timepiece such as a wristwatch comprising two superposed top and bottom date rings, the surface of which is divided into a plurality of sectors, the ring sixteen sectors, fifteen of which respectively bear fifteen successive markings of a cycle of 31 positions, and the sixteenth of which is a surplus sector with an open or transparent window, while the lower ring comprises seventeen sectors, sixteen of which are respectively the other sixteen markings of the 31-position cycle, and the seventeenth of which is one excess sector, each of these rings cooperating with drive means in such a way that the markings of the lower ring appear successively in a display area through the window, the upper ring remaining stationary, then, lower ring being stationary, the markings of the upper ring appear successively in the display area, the upper ring covering the markings of the lower ring, the date mechanism being characterized in that each ring comprises two peripheral teeth each of a succession of regularly spaced teeth, these peripheral teeth extending according to two stepped rows, respectively upper and lower, the teeth of the
  • the present invention provides a date mechanism comprising two superposed calendar rings and a fast correction device for quickly changing the information provided by the date mechanism.
  • the correction device is located opposite the toothless place of the toothing of this ring. As a result, the correction device can only act on the other ring, so that the risks of disordering the date mechanism are avoided.
  • the correction device comprises a sliding pinion.
  • the sliding pinion meshes with the teeth of the calendar rings only when it is moved by the user by means of a correction rod.
  • the date mechanism comprises jumper locking means, the lower date ring comprising an additional toothing located under the lower teeth of this ring and whose teeth are arranged in coincide with those of said lower toothing. Thanks to these characteristics, the jumper device is easy to manufacture and allows the two date rings to be properly positioned. Indeed, unlike the prior art where, because a place of the teeth of each of the calendar rings is toothless, the jumpers must be double top and press between the tips of three successive teeth, the jumpers according to the invention are constantly housed between two successive teeth of one or other of the teeth of a given ring, so that they remain in engagement with the date ring concerned, even during the passage of the missing tooth.
  • jumpers according to the invention are therefore classically terminated by two inclined planes that support between the tips of two teeth immediately successive to maintain the date rings in the desired position. These jumpers are therefore of conventional design and exert on the calendar rings a constant intensity of retention force, regardless of the position of said rings.
  • the present invention proceeds from the general inventive idea of providing a date mechanism for a timepiece comprising on the one hand a drive wheel making a turn every twenty-four hours and driving the calendar rings by action. on their teeth, and secondly a correction device for quickly changing the indications provided by the date mechanism.
  • the date rings each comprise two inner peripheral teeth, one of which is intended to cooperate with the drive wheel, while the other cooperates with the correction device. Furthermore, a location of each of these teeth is toothless to define an extended rest position of the ring considered.
  • the present invention aims to provide a date mechanism of the kind described above which the jumper device for arresting effect comprises two jumper space-saving, simple to manufacture and ensuring proper positioning of the date rings.
  • each of the two date rings comprises two sets of teeth with teeth superimposed, the location of the missing tooth for the two toothings are not the same, so that the jumpers are constantly housed between two successive teeth of one or other of the teeth of a given ring and therefore remain in engagement with the date ring concerned, even when passing the missing tooth.
  • the figure 1 is a top view of a watch movement comprising a date mechanism according to the invention.
  • the date mechanism according to the invention mainly comprises a ring of upper date calendar 4 superimposed on a lower date ring 6.
  • the upper date ring 4 has sixteen sectors, while the lower date ring 6 has seventeen sectors.
  • the upper ring 4 covers fifteen of its sectors markings "17" to "31", while the last sector is provided with an open or transparent window 8.
  • the lower ring 6 has meanwhile on sixteen of its sectors markings "1" to "16", while the last sector is free marking.
  • the inner circumference of the upper date ring 4 comprises a toothing formed of a succession of regularly spaced teeth.
  • this single toothing is formed of two upper and lower staggered teeth, the teeth of which are designated respectively by 10 and 12 are superimposed, a place 14 of the upper toothing and a location 16 of the lower toothing being toothless (see figure 4 ).
  • the inner circumference of the lower date ring 6 comprises two peripheral teeth each made of a succession of regularly spaced teeth, these peripheral teeth extending in two stepped rows, respectively upper and lower, the teeth 18 of the row being offset relative to the teeth 20 of the lower row (see figure 5 ).
  • the toothing of the lower row is formed of two lower and additional staggered teeth whose teeth, designated respectively by 20 and 22, are superimposed.
  • a location 24 of the upper toothing and a location 26 of the lower toothing are toothless.
  • the date mechanism comprises a date drive wheel 28 making a turn every twenty-four hours and which drives the calendar rings 4 and 6 by action on the teeth 10 and 20 of the upper toothing of said upper ring 4 and the lower toothing of said lower ring 6.
  • the position of the drive wheel 28 relative to the upper and lower teeth respectively of the upper 4 and lower 6 rings is such that when one of these rings has its free position (window 8 for the upper ring 4 and unmarked sector for the lower ring 6) at the display location 30 of the watch movement 1 (dial counter assumed to be removed and which would occupy the position where the figure "16") is visible, the drive wheel 28 is opposite the missing tooth, respectively 14 or 26, of the upper toothing of the upper ring 4 or of the lower toothing of the ring i lower 6.
  • the date mechanism also comprises a correction device for quickly changing the indication provided by said date mechanism.
  • this correction device comprises a sliding pinion 32.
  • This sliding pinion 32 is actuated by the user by means of a correction pin 33 and drives the date rings 4 and 6 by action on the teeth 12 and 18 of the lower toothing of said upper ring 4 and the upper toothing of said lower ring 6.
  • the position of the sliding pinion 32 with respect to the lower and upper sets respectively of the upper and lower rings 6 and 6 is such that when one of these rings has its free position at the display position 30 of the watch movement, the sliding pinion 32 is opposite the missing tooth, respectively 16 or 24, of the lower toothing of the upper ring 4 or the upper toothing of the lower ring 6.
  • a jumper locking device 34 comprises two jumpers 36 and 38 which cooperate respectively with the teeth 10, 12 of the upper and lower teeth of the upper ring 4 and with the teeth 20, 22 of the lower and additional teeth of the 6.
  • the jumpers 36 and 38 according to the invention are constantly housed between two teeth immediately successive of one or other of the teeth of a given ring, so that they remain in engagement with the relevant date ring even when passing the missing tooth.
  • the date rings 4 and 6 each have an abutment, respectively 40 and 42.
  • figures 4 and 5 show the detail of this arrangement.
  • the abutment 40 extends perpendicular to the plane of the upper date ring 4, while the abutment 42 extends radially out of the outer perimeter of the lower date ring 6.
  • the upper date ring 4 has its window 8 at the display location 30 and simultaneously its missing teeth 14 and 16 vis-à-vis respectively the drive wheel 28 and the sliding pinion 32. It is understood that the missing teeth 14 and 16 define a rest position of the upper date ring 4, position in which neither the drive wheel 28 nor the sliding pinion 32 can act on said upper date ring 4.
  • the wheel drive 28 therefore drives only the lower date ring 6 which, to achieve the position shown, has been conducted successively in situations where he exhibited markings "11", "12", ..., "15” and finally "16". At the moment when the marking "16" appears, the stop 42 comes to bear against the stop 40.
  • the ring 4 will also be driven, so that the window 8 will disappear from the display location 30 to make room for the marking "17" of the upper ring 4.
  • the lower ring 6 which will present its missing teeth facing, respectively, the drive wheel 28 and the sliding pinion 32.
  • the missing teeth 24 and 26 of the lower ring 6 define a rest position of this ring 6, position in which neither the drive wheel 28, nor the sliding pinion 32 can act on said lower date ring 6.
  • the sliding pinion 32 does not mesh with the teeth of the when it is set in motion by the user by means of the correction rod 33. During normal operation of the date mechanism, the sliding pinion 32 occupies a position away from the date rings 4 and 6. Finally, it will be noted already that the drive wheel 28 drives the date rings 4 and 6 by means of a finger having a certain elasticity, so that when one of the rings 4 or 6 is driven by the sliding pinion 32, the finger is erased in front of the tooth which is passing it and falls into the hollow defined by this tooth and the next tooth.
  • the figure 7 is an exploded view of the watch movement 1 provided with the date mechanism according to the invention.
  • This movement 1 comprises the plate 2 which supports and rotates the two lower and upper date rings 6 and 4.
  • In the center of the plate 2 is conventionally the axis of the hour wheel 44 on which the hour wheel is engaged. 46.
  • a bridge 48 carries the stop device 34 provided with its two jumpers 36 and 38 which act respectively on the upper date ring 4 and on the lower date ring 6.
