Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, to a mechanism for displaying a horological value composed of two digits, which makes it possible to maximize the size of the digits.
  • a standard-type date display mechanism comprises a date disc, typically of annular shape, bearing a series of numbers from 1 to 31 visible sequentially through an aperture made in the dial.
  • This arrangement is very limited in terms of the size of the digits which can be displayed and, in order to solve this problem, various so-called "big date” displays have been developed in order to improve readability.
  • these devices include a tens disc, bearing digits representing the tens of the date, and a units disc bearing the digits representing the units of the date.
  • the date displayed is therefore made up of a digit carried by the units disc as well as a digit (or, as an alternative to the digit "0", a space) carried by the tens disc, these two digits appearing through one or two counters.
  • Other more complicated arrangements are also known, but are not particularly relevant to the present invention and will therefore not be discussed here.
  • the object of the invention is therefore to provide a display mechanism in which the defects mentioned above are at least partially overcome.
  • said units programming wheel is arranged to cooperate with said units mobile via a first self-locking gear
  • said tens programming wheel is arranged to cooperate with said tens mobile via of a second self-locking gear.
  • Said tens wheel set is pivoted around said first axis of rotation by means of a tens ball bearing and said units wheel set is pivoted around said first axis of rotation by means of a unit ball bearing, a first of said tens ball bearing and said unit ball bearing being mounted on a support for attachment to a frame member, a second of said tens ball bearing and said unit ball bearing being mounted between said tens mobile and said units mobile.
  • these constructions allow the use of discs of units and tens of relatively large size, the use of self-locking gears being able to avoid the use of jumpers, which are energy-intensive. Consequently, the driving torque is not too high, which allows the indication of the date or other information to occupy a relatively large surface, in particular when the figures are at 3 o'clock with respect to the first axis. .
  • these constructions can be designed with a relatively small number of axes of rotation and without crowns (if desired), which limits the number of bearings necessary and the bulk in the movement, and, in combination with the arrangement specific to the components pivoted around the first axis, facilitates assembly of the mechanism, including the indexing of the various components.
  • said mechanism further comprises an additional control wheel which is pivoted around the same axis of rotation as said control wheel and is arranged to be driven by said control wheel and to drive said programming wheels, said additional control wheel being indexable with respect to said control wheel at the rate of said step of 1/ n turn by means of a jumper, which therefore ensures discrete relative angular positioning, a manual correction member being arranged to be able to pivot said control wheel additional to said control wheel.
  • a correction of the displayed value can thus be carried out in discrete steps, and this in both directions, while maintaining the synchronization of the mechanism.
  • said input wheel is arranged to cooperate with said control wheel via a third gear self-locking, which ensures training and positioning of the control wheel without the use of a jumper, and avoids double jumps.
  • said first axis of rotation is intended to be placed at the center of a basic movement, which makes it possible to maximize the surface occupied by the digits.
  • said tens programming wheel is arranged to cooperate with said tens wheel set via yet another additional self-locking gear, and/or said units programming wheel is arranged to cooperate with said units wheel set by intermediary of yet another self-locking gear.
  • said input wheel is pivoted around said first axis of rotation and intended to be driven by a basic movement, which is preferably mechanical.
  • the mechanism comprises a second axis of rotation about which said control wheel, said units programming wheel and said tens programming wheel are pivoted.
  • the number of axes in the mechanism can thus be minimized.
  • the invention also relates to a watch movement comprising a display mechanism as defined previously.
  • At least one, preferably each, of the units disc and of the tens disc has an outside diameter which is greater than or equal to 75%, preferably greater than or equal to 80%, preferably greater than or equal to 90% of the diameter of a circle of maximum diameter which lies entirely within the circumference of said movement.
  • said movement further comprises at least one time indicator hand which is arranged coaxially with said first axis of rotation, the axis or barrel of this hand passing, for example, through corresponding openings with which the mobiles mounted around it are provided. of the first axis.
  • This movement can, of course, be incorporated into a timepiece such as a pocket watch, a wristwatch or the like.
  • said indexing of said step d) may comprise the sub-step of: d1) Secure assembly elements to said wheel (i.e. the tens wheel or the units wheel, as the case may be) and to said disc (i.e. the tens disc or the units disk, if applicable).
  • said assembly elements comprise pins, which are preferably driven into the corresponding elements to which they are secured.
  • the figure 1 shows overviews of an embodiment of a watch value display mechanism 1 according to the invention, which has been constructed in the form of a large date display mechanism.
  • a watch value display mechanism 1 which has been constructed in the form of a large date display mechanism.
  • other displays are possible, such as a display of the week number, the month, the year, the hours, or the like.
  • the modifications made to the mechanism illustrated and described below to provide a display of other horological values are, of course, within the abilities of those skilled in the art. There is therefore no need to describe them in detail.
  • the figure 1 serves in particular to identify the various axes in order to simplify the interpretation of the views in section of the various levels of the construction represented by the figures 3 to 11 .
  • the picture 2 illustrates, on an exaggerated vertical scale, a side view of part of the mechanism 1, in order to identify the various levels N1 to N9.
  • the figures 3 to 11 represent cross-sectional views through each level N1 to N9 respectively, defined along the corresponding lines illustrated on the figure 2 .
  • each mobile will be identified by a reference sign made up of two digits, the first of which represents the level and the second represents the axis. Consequently, the input wheel 21 is at level 2 in rotation around the axis A1, the wheel 13 at level 1 around the axis A3, etc.
  • Elements such as pins, axial extensions, etc., which extend from one level to another are identified by reference signs, one of the numbers of which corresponds to one of the levels in question. Thanks to this encoding of the reference signs, it is not necessary to specify the length and width of the level and the axis of each element, which simplifies reading.
  • a minor exception to this principle is found on the figure 14 , which represents an inverse construction of that of the figure 13 , but still keep the same reference signs for the elements in question in order to facilitate understanding and to keep a single reference sign per functional element.
  • the axes A1 to A5 are geometric axes, the pivoting of the various elements taking place by means of ad hoc means such as shafts, bushes, ball bearings, etc., in a known manner.
  • the time display members can share the same axis, their shafts and barrels passing through the center of the elements of the mechanism 1 which pivot around the same axis.
  • the axis A3 corresponds to the “second axis” of the claims.
  • the mechanism 1 can, of course, be modular, taking place on the dial side of a basic movement, or can be constructed in an integrated manner.
  • Said power input is an input wheel 21, which is integral in rotation with an hour wheel in the case in point, arranged to perform one revolution per twelve hours. Other arrangements are also possible.
  • This input wheel 21 has four effective teeth on a base of 31 teeth.
  • the wheel has four recesses of teeth 21a at its periphery, defining said effective teeth, three long teeth 21b (conventional) each being located between each pair of adjacent recesses 21a, the outer recesses 21a being connected by a locking surface 21c with a substantially constant radius.
  • This blocking surface 21c occupies the place of the 27 “missing” effective teeth. Thanks to the arrangement which has just been described, it is the number of hollows of teeth 21a which corresponds to the number of effective teeth instead of the number of vertices, and any calculation of gearing is therefore made in relation to the number of hollow 21a. In simple terms, the four recesses 21a drive a first pinion 22 at the rate of four pitches of its teeth; therefore, the number of effective teeth is four.
  • the input wheel 21 therefore cooperates with the first pinion 22, which has eight teeth, so that, with each rotation of the input wheel 21, the first pinion 22 performs a half turn, therefore a complete turn by day in two discrete steps of 180° which take place around 12:00 and 24:00.
  • the first pinion 22 is not cooperating with the four effective teeth of the input wheel 21, the sides of two of its adjacent teeth can slip on the blocking surface 21c, which holds the first pinion 22 in its angular position.
  • the assembly of the input wheel 21 and the first pinion 22 therefore constitutes a self-locking gear, the blocking surface 21c ensuring the positioning of the pinion 22 without requiring a jumper.
  • self-locking gears help minimize energy consumption and avoid double jumps during training.
  • a second pinion 12 located at level N1 ( picture 3 ) has climbed.
  • This second pinion 12 comprises two effective teeth on a base of eight teeth, these two effective teeth being constituted by two tooth recesses 12a separated by a conventional tooth 12b, the rest of the periphery of the pinion being constituted by a blocking surface 12c with a constant radius.
  • the second pinion 12 cooperates with a control wheel 13 having 62 conventional teeth.
  • the control wheel 13 advances at the rate of two steps of its teeth (thanks to the two effective teeth of the second pinion 12), the input wheel 21 being arranged with respect to the hour and minute hands so that the second pinion 12 drives the control wheel 13 around midnight.
  • the control wheel 13 thus completes a complete revolution in 31 days.
  • control wheel 13 is designed and arranged to be driven at the rate of steps of 1/ n revolution under the direct or indirect control of the input wheel 21, n being a non-zero natural whole number .
  • n being a non-zero natural whole number .
  • 1/4 or 1/31 revolution per step is usual; for a week number display, 1/4 or 1/53 turn per step would be particularly suitable.
  • the teeth of the control wheel 13 cooperate with the blocking surface 12c of the second pinion 12 in order to position said control wheel 13 angularly when it is not in being trained.
  • the control wheel 13 is integral in rotation with a second toothing 23bis, having 31 teeth in the form of columns or equivalents (for example, pins) extending parallel to each other from the upper face of the control 13.
  • the toothing 23bis is made integral in rotation of an additional control wheel 23 via a jumper 23b, 23c which is carried by the additional control wheel 23.
  • the jumper comprises a substantially rigid element 23c, which extends radially and whose apex penetrates into the toothing 23a, and a substantially flexible element 23b, which takes the form of a flexible guide.
  • the jumper is designed and arranged so as to exert a force large enough to be secured in rotation to the toothing 23bis during the automatic drive (by the basic movement) of the date, but small enough to be unindexed in rotation of the toothing 23bis during manual training (by the user, during a correction) of the date; the additional control wheel 23 can therefore be integral with or deindexed in rotation from the control wheel 13.
  • the additional control wheel 23 comprises a toothing of 62 teeth, intended to be in kinematic connection with a manual correction device (not shown) through an appropriate correction system (not shown).
  • Such systems are well known to those skilled in the art and need not be described in detail here.
  • the toothing 23bis serves as a guide bearing for the additional control wheel 23 which comprises an inner wall 23f extending over an arc of a circle of more than 180°, in particular approximately 270°. Consequently, this wall 23f can slide on the toothing 23bis, and the additional control wheel 23 is thus guided radially.
  • the additional control wheel 23 can be a crown having an internal toothing which cooperates with a conventional jumper mounted on the control wheel 13, said crown being pivoted in an ad hoc manner on the control wheel 13.
  • the additional control wheel 23 carries a plurality of pins 23a which make it integral in rotation with a unit programming wheel 33.
  • a unit programming wheel 33 any other suitable means for integrally rotating these two wheels 23, 33 can be used.
  • the units programming wheel 33 comprises, on a basis of 62 effective teeth, 60 effective teeth as well as a blocking surface 33c corresponding to the two “missing” effective teeth.
  • This wheel 33 and a pinion 34 with eight effective teeth form a self-locking gear arranged so as to drive the pinion 34 in rotation at the rate of a quarter turn at the end of each day, except one day out of 31, which corresponds to the transition between the indications "31" and "01".
  • the locking surface 33c prevents any rotation of the pinion 34 in the same way as already described in the context of the self-locking gears mentioned above.
  • the pinion 34 is fixed in rotation to a drive wheel of the units 64.
  • This wheel 64 comprises four pairs of recesses 64a separated by a conventional tooth, thus defining four pairs of effective teeth.
  • this wheel 64 drives a mobile of the units 61, 71 at the rate of two pitches of the teeth of a wheel of the units 61 which has 20 effective teeth and is integral in rotation with a disc of the units 71 which carries the digits of the units.
  • the gear between the unit drive wheel 64 and the unit wheel 61 constitutes a self-locking gear which functions analogously to the self-locking gears previously described.
  • the unit disk 71 is pivoted on a ball bearing (see below) and has ten fingers 71a extending from its periphery and in its plane, the part of the periphery which is located between these fingers 71a having a radius constant.
  • This disc is positioned by a pair of jumpers 101 which, when the unit disc 71 is in a stable position, are in contact with two of said fingers 71a, one of the jumpers preventing clockwise rotation, the other preventing counter-clockwise rotation.
  • the tops of the jumpers 101 are located opposite a part of the periphery of the disk 71 with a constant radius and oppose no (or only little) resistance.
  • jumpers 101 are optional and can therefore be absent, in particular if the angular play of the disc of the units 71 generated by the self-locking gears is small enough to avoid any angular "floating" of said disc 71.
  • the tens programming wheel 43 has six pairs of effective teeth 43a on a base of 62 effective teeth, with locking surfaces 43c located between each pair of effective teeth 43a. These pairs of effective teeth 43a are arranged at appropriate positions on the periphery of the wheel 43 in order to rotate a pinion 45 with eight effective teeth at least during the transitions between the indications "09” and “10”, “19 and “20”, “29” and “30”, as well as “31” and “01”. Again, the gear between the wheel 43 and the pinion 45 is self-locking, as described above, the pinion 45 making a quarter turn each time a pair of effective teeth 43a pass.
  • the series of digits for the tens comprises once the sequence “0, 1, 1, 2, 2, 3”. Therefore, there are two additional drives, to make the transitions between the first digit "1" and the second digit "1", as well as between the first digit "2" and the second digit "2", at ad hoc times.
  • the number sequence and thus the number of trainings can be different. It is, for example, possible to provide one of the following other sequences: "0, 1, 2, 3", “0, 1, 1, 2, 3", “0, 0, 1, 1, 2, 2, 3”, “0, 1, 2, 3, 0, 1, 2, 3” or any other ad hoc sequence.
  • the pinion 45 is fixed in rotation to a tens drive wheel 55, which is similar in shape to the units drive wheel 64, except that its diameter is greater.
  • this wheel 55 drives a tens wheel set 51, 81 at the rate of two pitches of the toothing of a tens wheel 51 which has 12 effective teeth and is integral in rotation with a tens disc 81 which carries the tens digits.
  • the gear between the tens drive wheel 55 and the tens wheel 51 is self-locking, as previously described.
  • the tens disc 81 has six fingers 81a extending from its periphery and in its plane, the part of the periphery which lies between these fingers 81a having a constant radius.
  • a pair of jumpers 201 functions in the same way as the pair of jumpers 101 of the unit disc 71, mutatis mutandis, and therefore need not be described in detail.
  • the two discs 71, 81 have external diameters which are substantially identical, this diameter corresponding to more than 90% of the diameter of a circle of maximum diameter which falls entirely within the circumference of the movement base and/or of the dial 91.
  • the latter which is supported at its periphery by a support 6 in the form of an arc of a circle, is illustrated on the figure 11 , by the view in section through the mean plane of the dial 91, this figure showing the aperture 91a of relatively large size which reveals the figures making up the date (that is to say a figure or a space carried by the disc tens 81 as well as a number carried by the units disc 71) at 3 o'clock with respect to the axis A1.
  • the counter 91a can, alternatively, be located at 9 o'clock or elsewhere with respect to the axis A1, but an arrangement at 3 o'clock makes it possible to maximize the size of the digits since the ten digits of the units are arranged according to a circle of greater radius than that of the circle according to which the digits of the tens are arranged, which are typically less numerous. It is also noted that the presence of the dial is not mandatory.
  • the disc of units 71 can be either transparent or opaque. This arrangement avoids the presence of a perceptible separation between the two digits, the tens digits being provided either on the upper face (dial side) of the tens disc 81, or on its lower face (bottom side) as disclosed in the patent EP1070996 . In any case, the units digits are typically provided on the upper face (dial side) of the units disc 71.
  • the construction described previously only represents one non-limiting embodiment in the specific context of a large date, even if it is particularly advantageous.
  • a person skilled in the art can in particular adapt the gear ratios, according to his needs, to display other horological values.
  • the arrangement of the five axes A1-A5 may be different.
  • the elements mounted on the axis A3 can be distributed over several axes, additional ad hoc members can be provided in order to form all the necessary kinematic connections. Specific variants will be described below, following a description of the assembly of the elements pivoted around the axis A1.
  • a support 3 is provided, secured to a frame element (not shown).
  • This support comprises a disc part 3a, which extends radially at levels 3 and 4, as well as a tubular part 3b (which can alternatively be cylindrical in the event that no tree passes through it), which extends axially from the internal diameter of the disc part 3a in the direction of the dial 91.
  • This tubular part 3b serves as a support for a tens ball bearing R1, of which a first part R1a is integral with the support 3, being there tightened by means of a retention element such as a screw 5 which is screwed onto the tubular part 3b of the support 3, and of which a second part R1b is integral with the tens wheel 51 (for example, by being there driven, riveted, glued, welded or similar).
  • This tens wheel 51 has an extension 51h, of which the tens disc 81 is secured by means of a plurality of pins 81g serving as assembly elements (in particular two in the illustrated embodiment, but a number higher is also possible).
  • a ball bearing of the units R2 comprises a first part R2a fitted around the extension 51h, the second part R2b surrounding this first part, the balls being arranged between these two parts in a known manner.
  • the second part R2b carries the units wheel 61 (which is driven, riveted, glued, welded or the like around the part R2b) as well as the units disc 71 (which is driven, riveted, glued, welded or the like around the part R2b) which is indexed in rotation with respect to the unit wheel 61 via a plurality of pins 61g.
  • the joining of the elements can be done by driving in, edging, gluing, welding or any other appropriate means.
  • the reverse actions according to the reverse order is used for the dismantling of this assembly.
  • other methods and constructions are possible, in particular with regard to other variants for ensuring the indexing between each wheel 61 respectively 51 and its corresponding disk 71 respectively 81. The method will therefore adapt according to the means chosen to ensure indexing.
  • the layout of the figure 14 represents an inverse construction, in which the mobile of the units 61, 71 is pivoted on the support 3 via the ball bearing of the units R2, while the mobile of the tens 51, 81 is pivoted around the mobile of the units 61, 71 through the tens ball bearing R1. Therefore, the differences between the figure 14 and the figure 13 concern exclusively the reference signs used to indicate the various elements, the reference signs for each functional element corresponding to those used previously, even if this is not in conformity with the encoding for this figure.
  • the modifications of the kinematics upstream of these two mobiles 61, 71 respectively 51, 81 in order to compensate for these changes are within the reach of those skilled in the art and should therefore not be described exhaustively.
  • the joining of the elements can be done by driving in, edging, gluing, welding or any other appropriate means.
  • the reverse actions according to the reverse order is used for the dismantling of this assembly.
  • other methods and constructions are also possible, as mentioned above. The method will therefore adapt according to the means chosen to ensure the indexing.
  • variant 1 the embodiment of the figures 1 to 13 will be referred to as "variant 1".
  • HAS new and in order to facilitate understanding, the same reference signs have been used, even if the encoding of the axis and the level is not always respected.
  • control wheel 13 could comprise 2 n effective teeth (instead of 62 effective teeth), n being a non-zero natural whole number, and that the additional control wheel 23 could be separated from the control wheel 13 in steps of 1/ n turn (instead of 1/31 turn) and have 2 n effective teeth (instead of 62 effective teeth), or other, insofar as it can be ensured that the unit programming wheel 33 and the tens programming wheel 43 are adequately driven.
  • This variant makes it possible to change the displayed value more quickly, at the cost of a higher number of coins.
  • the week number can thus be displayed over a very large area, the user having to make a correction at the end of each year so that the numbers "54”, “55”, “56”, “57”, “58” , “59” and “00” are not displayed.
