Definitions

  • the invention relates to timepieces provided with a date mechanism.
  • the invention particularly relates to timepieces with a large window equipped with two superposed calendar rings.
  • the analog display of the dates in the wristwatches generally uses a date ring equipped with 31 sectors bearing the markings from 1 to 31 for the different days of the month.
  • a watch has the disadvantage of presenting for each sector a field of reduced size to a 31 th of the circumference of the ring. In a small wristwatch, the size of this field is insufficient to present a sufficiently readable date display.
  • the patent application EP 1,536,299 discloses a movement provided with a counting mechanism and a cyclical watch window for a watch calendar, providing a large-format date information, substantially double that of the 31-sector calendar.
  • This mechanism comprises an upper ring provided with 16 sectors, having 15 successive markings of a cycle of 31 positions, the 16th sector being an excess sector having an open or transparent window.
  • the movement also includes a lower ring equipped with 17 sectors, presenting the other 16 successive markings of the cycle, the 17th sector being a surplus sector.
  • the upper ring is held stationary while a command scrolls by rotation the successive markings of the lower ring in the window in the upper ring.
  • the window is arranged under the window of a cover plate of the shows.
  • Each ring comprises peripheral teeth made of a succession of regularly spaced teeth, these peripheral teeth extending in two tiered rows.
  • the teeth of the upper and lower rows of the upper ring are superimposed.
  • the teeth of the upper and lower rows of the lower ring are shifted.
  • a location of each of the teeth of the upper and lower rings is toothless so that the upper ring can thus be held in the display position without being driven for the dates 1 to 16, the lower ring being held in a position without waiting to be driven for the positions 17 to 31.
  • the rings are provided with vertical projections, meshing in these positions. These projections are made in the outer periphery of the rings.
  • Two superimposed control wheels drive the upper and lower rings, respectively. These wheels perform a complete turn daily and are provided with an actuating finger for driving once a day a tooth of a lower or upper ring.
  • a correction mechanism makes it possible to modify the indication provided by the date mechanism.
  • Each ring has a complex three-dimensional structure, with teeth on several levels and abutments projecting from the flat display surface of the ring.
  • Such a structure involves a method of manufacturing by plastic molding, which induces a relatively thick ring that strikes the overall size of the movement. This in turn leads to a relatively expensive ring that increases the cost price of the movement.
  • the display of the dates would still benefit from being enlarged.
  • the invention proposes a date mechanism for a timepiece.
  • the mechanism comprises two calendar rings superimposed and provided with successive markings of date. These date rings are rotatably mounted relative to each other.
  • the upper ring has a window formed between two markings.
  • the rings have drive teeth, each tooth being associated with a marking or a window.
  • a control wheel has two superposed levels of teeth. These stages are coupled in rotation. Each stage comprises a portion provided with adjacent teeth and a portion free of teeth.
  • Each floor drives a respective date ring.
  • the toothed portions and toothless portions of the control wheel are configured such that during rotation of the control wheel, at least one tooth of the upper stage and one tooth of the lower stage simultaneously drive. the two rings, and so that a single date ring is rotated simultaneously by the other teeth.
  • the figure 1 more precisely represents an embodiment of a date mechanism 1 according to the invention.
  • This mechanism is intended to be mounted in the plate of a non-illustrated watch, typically a wristwatch intended to display the day of the month.
  • the mechanism 1 comprises an upper date ring 2 and a lower date ring 3.
  • the upper date ring 2 is superimposed on the lower date ring 3.
  • the date ring 2 has sixteen sectors regularly distributed on its circumference .
  • the sixteen sectors comprise on the upper face of the ring 2 successive markings ranging from "17" to "31", as well as a window 21 placed between markings "17” and "31".
  • the window 21 has a dimension sufficient to allow visualization of the markings present on the lower date ring 3.
  • Window means both a component made of material transparent to light or a through opening formed in the upper ring 2
  • the date ring 3 has sixteen sectors distributed regularly around its circumference. The sixteen sectors have on the upper face of the ring 3 successive markings ranging from “1" to "16".
  • the watch will typically have a cover plate of the mechanism 1, fixed to the platen of the movement of the watch. A window will be provided in this cover plate, so as to display markings present on the rings 2 and 3 in the window.
  • the Figures 2 and 3 more precisely represent the constituent details of the rings 2 and 3.
  • the date rings 2 and 3 respectively have bores 25 and 35 in their middle part.
  • Teeth 22 project radially inwardly of the bore 25 from an inner periphery 23 of the ring 2.
  • teeth 32 project radially inwardly of the bore 35 from a periphery.
  • the teeth 22 and 32 are evenly spaced along the inner peripheries 23 and 33 of the respective date rings 2 and 3.
  • a tooth 22 is associated with each marking 24 or window 21 of the upper date ring 2.
  • a tooth 32 is associated with each marking 34 of the lower date ring 3.
  • the mechanism 1 further comprises a control wheel 4 for driving the first and second rings 2 and 3.
  • the control wheel 4 performs a complete revolution in 31 days.
  • the control wheel 4 is notably driven in rotation by means of a pinion on the hour wheel 61 and by means of gears 62 and 63 which will not be further described here.
  • the control wheel 4 has first and second stages of teeth 41 and 42 superimposed.
  • the stages 41 and 42 each have on their outer periphery a portion provided with successive adjacent teeth and a portion without teeth.
  • the teeth are regularly distributed in the portion provided with teeth and spaced at an angle of 2 ⁇ / 31.
  • the stage 41 includes control teeth of the sectors "17" to “31” and the window 21. The portion free of teeth therefore extends between the teeth “window” and "17".
  • the stage 42 includes control teeth of sectors "1" to "16". The portion free of teeth therefore extends between the teeth "16" and "1".
  • the portion provided with teeth of a stage is placed in line with the toothless portion of the other floor.
  • the teeth of the stage 41 controlling the markings "17” to "31” of the ring 2 are disposed in line with the portion of the stage 42 without teeth.
  • the toothless portion of the stage 41 is placed vertically above the teeth of the stage 42 controlling the markings "2" to "16" of the ring 3.
  • the tooth of the stage 41 which control sector “1" of the ring 3 is disposed vertically above the tooth of the stage 42 which controls the window 21 of the ring 2.
  • the first and second stages 41 and 42 are coupled in rotation, so that a simple rotation of one revolution of the wheel 4 makes it possible to drive one or the other of the two rings 2 and 3.
  • the stages 41 and 42 are configured to respectively drive the rings 2 and 3 by their portions provided with teeth.
  • Multiplying mobiles 11, 13 make it possible, in particular, to provide a respective kinematic link between the stages 41 and 42 and the rings 2 and 3.
  • the multiplier mobiles make it possible in particular to guarantee that the daily rotation of the wheel 4 involves a rotation of a ring of date of a date to the next date.
  • the stage 41 is coupled to the ring 2 by means of a first multiplier gear 11, a third multiplier gear 13 and the upper gear of a corrective gear train 9.
  • the gear multiplier 11 comprises a pinion 112 driven by the toothed portion of stage 41.
  • the multiplier gear 11 furthermore comprises a wheel 111 fixed to pinion 112.
  • the multiplier gear 13 comprises a pinion 131 driven by wheel 111.
  • the multiplier gear 13 further comprises a wheel 132 fixed to the pinion 131 and driving the upper gear of the corrective gear train 9.
  • the stage 42 is coupled to the ring 3 by means of a second multiplier gear 12, a fourth multiplier gear 14 and the lower gear of the correction gear train 9.
  • the multiplier gear 12 comprises a pinion 121 driven by the toothed portion of the stage 42.
  • the multiplier gear 12 further comprises a wheel 122 fixed to the pinion 121.
  • the multiplier gear 14 comprises a pinion 142 driven by the wheel 122.
  • the multiplier gear 14 further comprises a wheel 141 fixed to the gear 142 and driving the lower gear of the corrective gear train 9.
  • the first and second multiplier gears 11 and 12 are rotatably mounted about the same axis.
  • the first and second multiplier gears are independent of each other.
  • the third and fourth multiplier gears 13 and 14 are rotatably mounted about the same axis.
  • the third and fourth multiplier gears are independent of each other. Because these multiplier gear pairs are mounted on common axes, the mechanism 1 obtained is relatively compact.
  • the operation of the mechanism 1 is as follows. It is assumed that the opening 21 and the marking "1" are initially placed under the window of the cover plate. The first day of the month is displayed for the user.
  • the rings 2 and 3 are only slaves of the teeth of the floors 41 and 42 respectively, which allows the use of simple teeth formed in the thickness of the ring and regularly distributed along the inner periphery thereof. It should be noted in particular that there is no interaction between the two rings. Moreover, a single stage of teeth on each ring is sufficient to ensure its training.
  • the simplicity of the drive and the shapes of the rings 2 and 3 also makes it possible to produce them with thin metal sheets, which makes it possible to reduce their thickness and therefore the thickness of the resulting date mechanism for a given stiffness and resistance.
  • the date rings 2 and 3 are advantageously flat, so that the mechanism 1 is compact and its implementation simplified.
  • the rings 2 and 3 can be made for example by cutting in a metal sheet using any suitable technique such as stamping, laser cutting, water jet cutting or other.
  • the teeth 22 and 32 will thus have the same thickness as the body of the ring presenting the markings.
  • the rings 2 and 3 must be held slightly apart from each other for example by embossing bumps in the lower date ring 3.
  • the ring 3 does not require additional sector free of marking.
  • the size of the markings 34 on this ring 3 is increased.
  • the rings 2 and 3 may have the same number of teeth (16 in this case). The manufacturing processes of rings 2 and 3 can thus be extremely close, which reduces their cost price.
  • the control wheel 4 comprises in this case cut metal sheets forming the toothed stages 41 and 42.
  • a rivet 43 allows in particular to couple the stages 41 and 42 and also to guide the control wheel rotates through its median port.
  • the invention has been described with calendars corresponding to days of the month, the invention also applies to any other type of calendar, for example the seven days of the week, the weeks of the year, or the twelve months of the year, the control wheel having a portion provided with a number of teeth equal to (1 + Q) / 2, where Q corresponds to the number of calendars to be displayed
