Definitions

  • the present invention relates to a timepiece comprising a date indicator and at least one rotary indication means, driven by said date indicator, intended to indicate cyclic parameters such as the date, the lunar phase, etc.
  • the date ring with external toothing is narrower than the date indicator of a watch with aperture (col 2, lines 32 to 39). Indeed, with a larger ring, it would not be possible to integrate the various drive elements of the display hand.
  • the date ring as defined in the cited document, cannot therefore be used to display the date through a window, since there is not enough space to enter the numbers.
  • This indication function being the main and essential function of a date indicator, as it is known from the state of the art, the date ring described in the cited document has a form, an operation, as well as a function essentially different from a date indicator used in watches of known type.
  • the date ring described is simply a drive ring, with driven internal toothing and conductive external toothing. Furthermore, the dial support raises the assembly.
  • the distance between the dial and the date ring is very important. With such a configuration, even if it were possible to write the date numerals on the ring, the resulting display would not have good readability characteristics because the numbers would be too far from the dial. In addition, four cuts are necessary in order to make the drive parts, and several new parts, including the date bridge, are added to the original frame for driving the needle.
  • This device therefore makes it possible to use the dial as an additional display member.
  • This solution is however difficult to apply if a large number of rotary indicators possibly rotating at different angular speeds must be provided in the watch. In this case, a plurality of wheels concentric with the watch must be superimposed, which results in a significant excess thickness of the watch. On the other hand, it is difficult to obtain a readable display with a plurality of concentric indicators. The different wheels must also be placed at different distances from the dial and the glass, which considerably affects the aesthetics and legibility of the watch.
  • Patent document EP-A-0 366 610 describes a watch in which various indicator members are driven by a week row wheel. This type of wheel is rather rare in a watch movement and must therefore generally be added to existing elements. This wheel has no internal toothing and does not serve as an indicator. This additional wheel increasing the movement price therefore fulfills no other function than driving various additional indicators.
  • Patent document CH 662 696 describes a watch movement comprising day and leap year indicators meshed by a zodiac wheel performing one revolution per year. This zodiac wheel is infrequent in watchmaking organs and must generally be added to the device. The additional day and leap year indicators are meshed directly, without an intermediate member, by the zodiac wheel, which limits the choice of placement of the indicators on the dial.
  • patent document CH-A-324,270 describes a watch movement comprising a wheel advancing two steps per 24 hours, and bearing the day unit indications, which drives a rotary member displaying the tens of days .
  • the main purpose of the present invention is therefore to design a timepiece of simplified construction offering greater possibilities of indications. This object is achieved thanks to the features of claims 1 to 15.
  • the timepiece according to the present invention allows the display of the date through a window and / or the display of at least one cyclic parameter, the duration of which can be expressed by a time function, depending on the date, by means of at least one rotary display means.
  • the date indicator used is identical to that of the prior art, used with aperture watches of known type; it retains its original width and the numbers indicating the date can be inscribed there. In this way, the date indicator offers more indication possibilities than a simple training ring.
  • the date indicator has internal teeth, the teeth of which are both driven and conductive. The distance between the date indicator and the dial remains small, which gives the whole a good readability. Only two cuts are necessary to make the drive parts for the rotary display.
  • a determined clearance located between the teeth of the intermediate star and those of the date indicator, fulfills a double function: it makes it possible to shorten the duration of the passage of step (jump) of the rotary display means and it avoids any disturbance of said means if the crown is rotated below a given angular limit, in the opposite direction to normal operation.
  • the window indicating the date can be placed at any angular position on the dial.
  • FIG. 1 represents a movement according to the present invention in which only the elements necessary for the understanding of the present description appear.
  • a date indicator 1 of known type, is driven in rotation respectively by the hour wheel 3 and the date driving wheel 4. The first makes two turns per day, while the second performs only one turn per day. Thanks to this type of training, the indicator 1 progresses by one step each day, this movement taking place in the shortest possible time interval, preferably at midnight.
  • Ring 1 has thirty-one teeth 2, each of them corresponding to a day of the month.
  • the jumper 6 of the date ring ensures rapid advance of the ring 1 when the latter is driven by the tooth 5 of the date driving wheel, as well as its positioning between the steps.
  • the device described above corresponds to that of a known type of movement, intended to indicate the date.
  • the date indications 7 are arranged in order on the date indicator, the main function of which is then to indicate the day of the month through a window provided for this purpose in the dial.
  • the timepiece according to the present invention uses the preceding elements, without it being necessary to modify them, in order to drive at least one rotary indication means 12 (fig. 2 to 5), making it possible to indicate any cyclic parameter, the duration of which can be expressed by a time function, depending on the date, such as for example the lunar phase, the "cash balance", the date, or other.
  • An indication control star 8 meshes with the internal teeth 2 of the indicator 1.
  • a pinion 9, integral and coaxial with the star 8 in turn drives an indication wheel 10 on which is centrally disposed an axis indication 16 (fig. 2). It is this axis of indication which drives the rotary indication means 12.
  • the jumper 11 of the control star stabilizes the control star 8 between the steps and adjusts the rapid advance of the indication means 12 so to allow the quickest possible passage of steps.
  • the rotary indication means 12 can vary according to the embodiment and / or according to the parameter to be indicated.
  • the rotary indication means 12 is a hand indicating the date; in FIG. 3, as well as in FIG. 5 (at noon) the means 12 is a rotating disc reproducing the lunar cycle through a window of suitable shape of known type; in FIG. 5 (at 6 am), the means 12 is a rotary needle indicating the "cash balance", that is to say the size of the bank balance (and / or in cash) still available until payment of the next salary.
  • the indication of "cash balance" 7a is a circular band whose width decreases along the circular path of the needle indicator.
  • This width is maximum at the start of the journey (after the payment of the salary, for example at the beginning of the month; the bank balance is then significant) and reaches its minimum for example towards the end of the month, before the payment of the next salary.
  • This strip may possibly be followed by a series of grooves arranged angularly, as shown in FIG. 5, for the few days preceding the payment of wages, where the bank balance may possibly become critical or negative.
  • the indication of "cash balance" can take a multitude of forms, where it suffices that the visual presentation shows the usual evolution of the bank balance as a function of time, preferably as a function of the days of a month.
  • the indication of "cash balance” 7a can use any symbol, sign or other, providing an indication to the user on the size of his bank balance, such as for example a piggy bank, represented more or less full depending on the size of the balance; a monetary symbol, such as that of the dollar, represented in different sizes in proportion to the size of the bank balance, this same symbol can be accompanied by an arrow whose height indicates the size of the balance (fig. 4), etc. .
  • the “cash balance” indications 7a are distributed over the date indicator 1 in place of the date indications 7 which are found on watches of known type, to be transmitted by the 'through a window 17.
  • the indication of "cash balance” 7a can be used with any type of timepiece used to indicate the "cash balance".
  • a rotary indication means 12 of a type similar to that used to indicate the date may also be used to indicate the rank of the week in the month or in the year.
  • the date indicator 1 when it moves one step, acts on the indication control star 8; the control pinion 9 then drives the indication wheel 10, causing an angular displacement of the rotary indication means 12.
  • the value of this angular displacement depends on the number of teeth of the wheels and the gear ratios between the wheels and the gables. These are determined according to the type of indication. For example, in the case where the date is indicated ( Figures 2 and 4), the numbers of teeth and gear ratios are established so that the needle moves one step each day, following the same cycle as the date indicator. In the case of the moon phase indication, the cycle of the indication means 12 is slightly shorter than that of the date ring, so as to correspond to the real lunar cycle.
  • a clearance A is determined between the tooth 2 located downstream of the active tooth of the control star 8 and the latter tooth, this clearance existing when the date indicator 1 is in the stationary rest position, in order to shorten the duration of the "instantaneous jump". Indeed, it normally takes a certain time (typically 1 to 2 hours) for the date indicator to advance by one step. Game A delays the effect of tooth 2, the star 8 is thus driven for a shorter time. This time is also optimized by the action of the jumper 11 of the control star. In this way we succeed in dividing by four or more, the duration of the "instantaneous jump" at the level of the rotary indication means 12. For example, an “instantaneous jump" taking place in twenty minutes (or less) now becomes possible.
  • the clearance B between the tooth 2 located upstream of the active tooth of the control star 8 and the latter tooth makes it possible to avoid any disturbance of the means of indication if the crown is turned to the towards.
  • This play is also present when the date indicator 1 is in the stationary rest position.
  • the date ring can thus be moved angularly (upside down from the normal operating direction) over a distance corresponding to the clearance B, without the star 8 being driven.
  • more than one rotary indication means 12 is used (as for example in FIG. 6), either in a dependent manner, that is to say by coupling one or more additional sets, complete or partial, of wheels and pinions to one or the other of the drive elements 8, 9, 10, 16; either independently, that is to say by using one or more separate additional sets directly coupled to the date ring 1; or by combining these two methods.
  • the timepiece according to the invention therefore makes it possible, from a movement with known date indicator, and adding only drive wheels and pinions (8, 9, 10, 11), to drive at least one rotary indication means 12 in a simple and economical manner.
  • the elements added to the basic movement are simple, few and inexpensive (in particular the jumper 11 which can be constituted by a simple spring strip). In addition, they do not affect the dimensions of the basic movement.
