Definitions

  • the present invention relates to a timepiece comprising a display mechanism arranged to control the movements of a display member facing an indicator scale comprising different indications having at least two different widths and being separated from each other. by corresponding separation spaces.
  • timepieces comprising a mechanism for displaying the date by means of a hand most of the time meet the characteristics stated above.
  • the indications of the twenties and thirties may possibly have one and the same width
  • the indications of the tens typically have a smaller width since the "1" has a smaller width than that of the "2" and / or " 3 "
  • the unit indications typically have an even smaller width since they have only one digit.
  • These display mechanisms generally include a display member driven by means of a conventional gear train, to move opposite the different indications with a constant movement pitch.
  • the separation spaces located between the indications have a variable width to allow the display member to be driven at a constant pitch despite the variable width of the indications.
  • the indications two date digits appear to be particularly close to each other when the date is displayed in a small counter.
  • a main aim of the present invention is to provide a timepiece offering an alternative presentation with reference to known timepieces in terms of display, in particular improved readability.
  • the present invention relates more particularly to a timepiece of the type indicated above, characterized in that the separation spaces all have substantially the same width.
  • the display associated with the mechanism according to the invention appears more homogeneous and ventilated than the displays of the prior art and is consequently more readable than the latter.
  • the actuating mechanism may include a cam against which a probe is arranged to bear, the probe being kinematically linked to the display mobile, the cam having at least two different slope values along its length. in such a way that the display mobile can be driven in rotation according to two different pitch values for a same rotation angle of the cam as a function of the orientation of the latter with reference to the probe.
  • the actuation mechanism may include first and second wheels that are partners of a non-circular gear or a first wheel that is partner of a non-circular gear, the display mobile comprising a second wheel. partner of the non-circular gear, the first and second partner wheels being arranged in such a way that they mesh with each other with a variable gear ratio, the display mobile being driven at at least two different pitches.
  • the display mobile comprises a toothing having at least two different pitches and arranged to cooperate, on the one hand, with a mobile for actuating the actuating mechanism and, on the other hand, with a jumper for maintaining the position and / or orientation of the display member, the teeth being indexed to the position of the indicator scale.
  • the actuating mobile and the jumper are preferably arranged such that the actuating mobile actuates one of the teeth with which the jumper cooperates, to move the display member.
  • the indications can be made for the indications to indicate the date and / or possibly to have three different widths.
  • the figures 1a and 1b represent a simplified view of a display of a timepiece, respectively according to the state of the art and according to the present invention.
  • the figure 1a shows a date counter 106 according to the state of the art, intended to be integrated into a dial of a timepiece.
  • Said timepiece comprises in particular a date display mechanism arranged to display the date value by controlling the movements of a hand 102 facing indications 104 arranged along an indicator scale 105, in the counter. date 106.
  • a visual examination of the indications 104 shows that they have different widths, which is obvious when one compares in particular the indications relating to units with those relating to tens, with those relating to twenties or even with that relating to thirties.
  • the hand 102 is carried by a date mobile (not visible) driven by a finger (not visible) to advance at least one step per day, the finger itself being driven by a mobile of twenty-four. hours (not visible).
  • a date mobile not visible
  • a finger not visible
  • Such an arrangement allows the hand 102 to advance at a constant pitch (without considering here the case of an annual or perpetual calendar mechanism which would allow the hand 102 to advance several steps in a row at the end of the month. less than thirty-one days).
  • the different indications 104 are separated by separation spaces 112. It is noted that the separation spaces 112 do not have the same width between two indications 104 associated with the units and between two indications 104 associated with the scores, for example. This conventional characteristic is in fact intended to ensure that the pitch separating two successive indications 104 is the same throughout the indicator scale 105, so that the positions of the indications 104 are correctly associated with the different positions that the needle 102 can occupy because of its standard training mode.
  • Such a display therefore presents a notable difference in the presentation of the date values between the start and the end of the indicator scale, which may not be suitable for everyone from an aesthetic point of view and somewhat reduces readability. in the regions of the scale where the indications 104 are closer to each other.
  • the aesthetic question is also present on a display arranged at the periphery of the dial, unlike the question of readability, these two aspects become more striking as the surface of the display concerned decreases.
  • the term "width” designates the dimension of the indication in the direction in which the indicator scale extends, parallel or tangentially to the indicator scale depending on whether it extends in a rectilinear manner. or curvilinear.
  • the indicator scale is circular over an amplitude of 360 ° and the width of an indication is its dimension in an ortho radial direction. This dimension can be expressed in the form of a distance or an angle in the case of a curvilinear scale.
  • the separation spaces represent a dimension measured in the direction in which the indicator scale extends so that the length or angular amplitude of the indicator scale is the sum of the widths of the indications and the spaces. of seperation.
  • the figure 1b shows a date counter 6 according to the invention, intended to be integrated into a dial of a timepiece.
  • said timepiece comprises in particular a date display mechanism arranged to display the value of the date by controlling the movements of a hand 2 facing indications 4 arranged along an indicator scale 5 in the meter 6.
  • the indications 4 also have different widths, as is the case with the indications of the state of the art.
  • the separation spaces 12 this time all have substantially the same width, whether between two indications 4 associated with the units or between two indications 4 associated with the scores, for example. A more pleasing to the eye perception is thus obtained, due to the regularity of the alternations between the indications 4 and the separation spaces 12 and it is also noted that the readability is increased with reference to the displays of the state of the art, more particularly at the level of the values of the twenties.
  • this step value will for example be lower between two indications 4 associated with date units than between two indications 4 associated with date twenties.
  • the present invention preferably provides that the display mechanism comprises a display mobile arranged to control the movements of the display hand 2, and an actuation mechanism arranged to cooperate with it. the display mobile and move it according to different successive positions associated with the indications 4, so that the different successive positions have at least two different pitches between them.
  • the display mechanism so that the needle 2 can move in such a way that its different successive positions have at least two different pitches between them.
  • the actuation mechanism may include a cam against which a probe is arranged to bear, the probe being kinematically linked to the display mobile, the cam having at least two different slope values depending on its length so that the display mobile can be rotated according to two different pitch values for the same angle of rotation of the cam according to the orientation of the latter with reference to the probe.
  • the actuation mechanism can include first and second partner wheels of a non-circular gear or a first partner wheel of a non-circular gear, the display mobile comprising a second partner wheel of the non-circular gear, the first and second partner wheels being arranged in such a way that they mesh with each other with a variable gear ratio, the display mobile being driven in at least two different pitches .
  • non-circular gear it should be understood, in a conventional manner, that it is a gear between two partner wheels having a contact region whose position, with reference to the centers of rotation of the partner wheels, depends on the angular orientation of the partner wheels.
  • the display mobile comprises a toothing 14 having at least two different pitches and arranged to cooperate, on the one hand, with an actuating mobile 16 of the actuating mechanism and, on the other hand, with a jumper 18 for positioning and maintaining the display mobile, the teeth being indexed to the position of the indicator scale 5.
  • the display mechanism partially illustrated in the figures is intended to display the perpetual calendar and its operation will not be fully described here since the basic principle is already presented in the patent.
  • EP 3026504 B1 on behalf of the Applicant.
  • the display member 2 is a needle which points to a date indication of the counter 6 while being integral with the display mobile.
  • the actuating mobile 16 here has the form of an actuating lever, by way of non-limiting illustration, the latter being pivoted along an axis of rotation X1 with reference to the frame of the watch movement.
  • the actuating rocker comprises an arm 20 intended to receive impulses from a driving wheel set (not visible) of the movement. watchmaker to rotate the actuating lever in the clockwise direction of rotation and to cause the display mobile to rotate.
  • the actuating lever carries a double nose 22 comprising first and second teeth 24 and 26 arranged to cooperate with the teeth 14 as described in the prior patent mentioned above.
  • the actuating lever cooperates in particular with a forty-eight cam 28, by means of a sensor 30, the forty-eight cam 28 comprising forty-eight notches of different depths and each of which corresponds to a given month among the forty - eight months of a leap cycle.
  • the first tooth 24 acts on the toothing 14 during the passage from one day to the next until the last day of a given month.
  • the second tooth 26 is intended to act on a suitable recess 32, made in the toothing 14, to change the date of the value of the last day of a given month to the first day of the following month when the current month has less than thirty-one days.
  • the information relating to the number of days in the current month is read on the forty-eight cam 28 by inserting the probe 30 into a given notch, which defines the starting position of the actuating lever and therefore its amplitude of pivoting, as disclosed in the aforementioned prior patent.
  • the double-nose 22 is carried by the actuating lever via a pivot connection associated with a spring 34 so as to form a pawl, retractable during the return of the actuating lever.
  • a double positioning member 36 maintains the respective angular positions of the forty-eight cam 28 and of the actuating lever when they are not rotated.
  • the display mechanism according to the present invention differs from the prior art in that the needle 2 moves in varying steps along the indicator scale 5. Apart from other possible constructions such as those mentioned above. high, it is possible to achieve a adapted drive of the needle 2 by producing a set of teeth 14 having teeth of variable width.
  • the date hand 2 is positioned opposite the indication 4 corresponding to the first of the month in the configuration illustrated on the figures 2a , 2b and 3 .
  • the angular position of the display mobile is determined by the two teeth of the toothing 14 which cooperate with the jumper 18.
  • a careful examination of the toothing 14 reveals that a first series of teeth 141, associated with the date units, has a first width and is followed by a second series of teeth 142, associated with the date tens, having a width slightly greater than that of teeth 141 of the first series, the second series being followed by a third series of teeth 143, associated with the date twenty, the width of which is very slightly greater than that of teeth 142 of the second series, the third series being finally followed by two teeth 144 for the thirty or so dates of width substantially identical to that of teeth 143 of the third series.
  • the actuating rocker when the actuating rocker receives an impulse, its first tooth 24 exerts pressure on the tooth of the toothing 14 located immediately upstream of the jumper 18 to rotate the display mobile, as illustrated in FIG. figure 3 .
  • the jumper 18 is located near the tooth of the set of teeth 14 intended to be driven by the first tooth 24 so that the tooth intended to be driven is in the path of the first tooth 24.
  • the role of the jumper is not only to ensure the maintenance and positioning of the display mobile with reference to the indicator scale 5 but also to position the toothing 14 with reference to the actuating mobile 16.
  • the display mobile has two distinct teeth, a first toothing cooperating with the jumper, and a second toothing. cooperating with the training mobile.
  • the first and second toothings have identical angular pitch variation sequences but have an angular orientation and / or different radii.
  • the set of teeth 14 is shaped such that its widest tooth has a width less than twice the width of its narrowest tooth. Such a limitation is not necessary in the case of asymmetric toothing.
  • variable-pitch operating principle does not modify the nature of the action of the second tooth 26 of the actuating lever on the toothing 14, at the end of short months, compared to what was described in the prior patent. cited above.
  • the toothing 14 has a tooth 141 'of length greater than that of the other teeth so that it can cooperate with the forty-eight cam 28 once a month to advance it from one month to the next. .
  • the implementation of the present invention is not limited to the display of the date. In fact, those skilled in the art will not encounter any particular difficulty in adapting the present teaching to the implementation of a display mechanism of a magnitude other than the date, whether it is displayed by numbers, words. or else by symbols of variable width, such as the phases of the Moon, for example.
