    Detailed description of the preferred embodiments
    The invention relates to a timepiece, in which the display of the quantities is distributed at the level of several entities, each activated at a particular time.
    In particular, the display of temporal quantities is broken down into slices, in particular into slices of equal magnitude. In particular, for the display of the time, among 12 or 24 entities, a single entity displays at a given moment the current time. Rather than juxtaposing different entities for different displays, the invention seeks to use the same entity for the display of two different horological magnitudes, for example hours and minutes. The choice of 12 entities for the display of the hours leads to the use of these same entities for the display of the minutes in 5-minute increments. Any rational combination of multiple integers allows for logical displays. Conversely, displaying the time on 24 entities would logically lead to displaying the minutes in 2.5-minute increments on each of them, which is impractical, but may be sufficient for street furniture clocks, or similar.

Depending on the configuration chosen, these mobiles can be solid, perforated, or even transparent and bear a marking. The number of cylinders chosen depends on the application chosen: for example and not limited to three, six, twelve or twenty-four for the display of the hour, six, ten, twelve or fifteen for the display of the minutes. or seconds, seven for the day of the week display, three, four, six or twelve for the month display, four, six, eight or twelve for the date display, four for the day display he single or leap year, the only limits are those of the complexity and volume of the mechanism associated with the complication selected.
    More particularly, in this embodiment illustrated by the figures, a display of the hours is carried out by means of indexes that comprise twelve rotary hour bodies 30, each housed in a cylinder 10 (at a rate of six per stage in this particular realization), at the rate of one rotation in 12 hours for each index. And another display of the minutes is carried out, in five-minute increments, by twelve pistons 8, which circulate linearly in the twelve hour bodies 30, with the indication of the 5-minute period which is in progress, by means of an optical indicator 14, made visible by a valve 16 open at the level of the piston 8 concerned, and easily visible to the user.
    The hours are thus displayed on substantially cylindrical hour bodies 30, housed in cylinders 10. These hour bodies 30 may comprise cut-out metal cylindrical cages, or the like, or else tubes of material. transparent, in particular sapphire or the like, bearing a marking, by metallization or laser engraving or the like, with the corresponding hour digits 301; the movement 200 of the timepiece 1000 drives each hour body 30, cage or tube so as to make two revolutions in 24 hours.
    Each cylinder 10 has a sealed envelope 20 for receiving this hour body 30 which surrounds a piston 8, this envelope 20 is transparent on at least one side visible to the user of the watch to read the time , and is for example made of sapphire or the like. This cylinder 10 can either be attached to the structure 900 or the caseband of the watch, or else form part of this structure 900 or of this caseband or of the case of the watch. The cylinder 10 whose legible numerical inscription on its hour body 30 faces directly the user is the active cylinder which provides the display of the current time.
    Advantageously, this cylinder 10 which is active for the display of the time is visually materialized by the very visible alignment of a dynamic index 307 carried by the hour body 30, and of a static index 308 that carries the cylinder 10, the supporting structure 900, the middle part, or the box.
    This concordance can be a visual concordance, it can also be mechanical, electrical, or magnetic, so as to reveal an active cylinder indicator of the hours. For example, in a mechanical variant, the hours body 30 may comprise, on the side of the structure 900, a lug, or a notch, or a cam, to cooperate with a lever housed in the structure 900 to the right of the cylinder, and the pivoting of which causes a flag to appear in a window, as known from patent EP2595006 in the name of BLANCPAIN SA, or similar. In a magnetic variant, the cooperation of magnets of the same polarity or of opposite polarity, carried by the hour body 30 and the structure 900, also allows the control of such a flag. In an electro-mechanical timepiece, an electrical contact in alignment with the indexes of the hour body 30 and of the structure 900 allows the control of a lighting function, or the like.
    Similarly, among the different cylinders 10, only one cylinder 10 is active at a given time for the display of the minutes. The display is made of that of the cylinders 10 which is active for the display of a 5-minute period by the highlighting of an optical indicator 14, in particular by the highlighting of the opening of the valve 16. , for example located at the distal end of the piston 8, opposite the crankshaft, visible by a very visible colored mark, for example a colored surface 140, red or similar; it will be understood that this valve 16 is, at a given instant, open at the level of a single cylinder 10, and closed at all the others; at the end of a 5-minute period, the valve 16 closes on the piston 8 of cylinder 10 which has just displayed the minutes, and opens on the piston 8 of the next cylinder 10, preferably by clockwise;
    In a particular variant, is carried out, in each 5 minute period, the display of the current minute by means of graduations 306 carried on the cylinders 10, or on the envelopes 20, or on the hour bodies 30; these graduations 306 can be equidistant, or else as here non-linear, because they depend on the linkage kinematics used; a mark on the piston 8, or the distal end of the piston 8, or the colored mark 140 on the valve 16, is easily readable against this graduated scale.
    The illustrated embodiment represents a good compromise between readability, aesthetics, and the space available for housing the different mechanisms. In this particular non-limiting case, it comprises:a gear train with conical teeth, actuated by the movement 200 of the watch 1000, and arranged to drive the hour bodies 30 in rotation;at least one central crankshaft 1, arranged to actuate the pistons 8 in a reciprocating movement in translation in their respective hour bodies 30;a piston valve 16 trigger mechanism, allowing a colored mark 140 to appear on the piston 8 concerned by the current minute segment, thus improving the readability of the time.
    The hours display more particularly comprises an hour body 30 which is a metal component with cut out hour digits 301, which improves visibility and readability.
    The crankshaft is necessarily complex, due to the number of the twelve moving parts to be controlled in this particular case. If a crankshaft plate with twelve connecting rods is conceivable, the size and the fragility of the mechanism lead to prefer solutions with several crankshaft plates 40 each involving a submultiple of 12: the illustrated version has two crankshaft plates 40 superimposed, each able to drive six pistons, with their trigger mechanism allowing the differentiation of piston 8 which displays the current minute.
    It is necessary to have a sufficiently dimensioned energy source, for a watch of large dimensions, for example with a casing diameter of about 43 mm, and an overall diameter of about 53 mm at the bottom. cylinder heads, with cylinders largely dimensioned to be clearly visible, with a height of 10 to 12 mm and a diameter of 8 to 12 mm, to guarantee a sufficient power reserve, greater than 50 hours. Indeed, the torque at the crankshaft is of the order of 3 N.mm. it is therefore chosen to install several barrels, for example each with a capacity of 8 or 9 N.mm: a configuration with four such barrels in parallel makes it possible to dispense a high moment of force, with such a power reserve. Other variants are possible, in particular and without limitation two pairs of barrels in series, placed in parallel in order to increase the power reserve, or even three barrels in order to save space.
    The movement 200 transfers the energy, by means of cogs, to a movement output mobile which drives the crankshaft 1, a minute release cam 2, and the hour pinions 3.
    The crankshaft 1 is a key piece, both in terms of its distribution function and in terms of its visual impact. Due to its many functions, it is necessary to have an extremely precise component, which is why it is advantageous to have a single-piece component, in particular guided between a stone on the one hand and a screwed bearing on the other go. This arrangement limits the risks of positioning faults linked to the overhang, and those linked to the accumulation of tolerances of an assembly, and also makes the component more reliable in order to maintain its high precision in the long term.
    In the illustrated version comprising two crankshaft plates 40, these two plates 40 each pivot around a crankpin 41 of the crankshaft 1, and each carries six connecting rods, one of which may be integral with the plate to form with it a large fixed connecting rod 4, the other small articulated connecting rods 5 pivot on plate pins 7 driven out on plate 40. The rotation of the large connecting rod must be as fluid as possible. A damper hub 6 is advantageously placed between the crankpin 41 of the crankshaft and the associated plate 40. A galvanic treatment of the Nickel PTFE type makes it possible to obtain a pivot point with good anti-seize and self-lubricating characteristics; the coefficient of static friction can thus be lowered to 0.15, and the coefficient of dynamic friction can be lowered to 0.10. This same galvanic treatment is also advantageously applied to the connecting rod-pin connections.
    Each connecting rod 4, 5 penetrates inside a piston 8, which comprises, in a radial bore, a fixing pin 9 around which its connecting rod pivots. The piston 8 must work freely with a degree of freedom perpendicular to the connecting rod in question; for this purpose the piston 8 has, for the passage of this connecting rod, an opening which is wide enough to allow the maximum working angles of the connecting rod. The fixing pin 9 is difficult to access for maintenance, and the piston 8 circulates in a highly visible area for the user, and therefore it is preferable to avoid any liquid lubrication causing at least visual pollution: the connection between the fixing pin 9 and its respective connecting rod is preferably also treated with a galvanic treatment of the Nickel PTFE type or the like.
    The piston 8 must have the best possible guidance, both precise and very fluid to prevent any risk of seizing and blocking of the mechanism.
    Among the possible solutions, the figures illustrate a guide of the piston 8 by two rods 12, here without limitation placed inside a cylindrical tube 20 made of sapphire. The piston 8 has two lateral notches 81 for receiving intermediate guides 13, or buffer pieces, which provide sliding guidance for the rods 12. Here too, a galvanic treatment of the Nickel PTFE or similar type is advantageous in order to reduce the coefficient of friction. and obtain a self-lubricated contact. The intermediate guides 13 are preferably substantially diametrically opposed, which ensures optimum distance and good guidance of the piston 8 on these rods 12.
    Another type of guide consists in guiding the piston 8 on the outside of the inner wall of a transparent tube 20, made of glass or sapphire, or the like, with in particular the interposition of buffer rings housed in circular grooves of the piston 8, and which buffer rings provide guidance in this transparent tube.
    To determine the 5-minute period in force, the mechanism according to the invention controls the triggering of the corresponding piston 8, by closing the valve 16 of the piston 8 of the 5-minute period which has just ended, and by opening the valve 16 of the piston 8 corresponding to the new 5-minute period which begins. The opening of the valve 16, which is preferably located at the distal end of the piston 8, opposite the crankshaft, reveals a very visible colored mark 140, for example a red surface, or a surface treated with a reflective material, or any other surface providing a good visual contrast with the outside of the piston 8. This visual mark 14 can naturally be used as an index, when the cylinder 30, or a transparent tube 20 which it comprises, has graduations 306, to determine the current minute within 5 minutes.
    Advantageously, the piston 8 comprises a piston body 15, and a valve 16, which makes the visual mark 14 visible once triggered, and which otherwise hides it, and which has a limited axial travel relative to the body piston 15. The valve 16 is pushed radially towards the outside of the watch, when triggered, by a valve control mechanism which will be presented below. When the valve 16 is engaged, it is held in position by an elastic mechanism, comprising a jumper 17 which maintains this valve 16 against a hooking part 18 fixed to the piston body 15.
    The valve control mechanism more particularly comprises a minute mobile 201, in particular a ring or a minute disc, which carries the cam 2, and is driven by the movement 200 of the watch 1000 and makes one revolution per hour . This cam 2 comprises a radial projection 202 with an upper track 208 of greater diameter than that of a lower track 209 which the rest of the cam 2 comprises, and to which it is joined by ramps 206. The cam 2 is arranged for radially push a feeler 19, specific to each piston 8, and which is guided in a fixed part of the structure 900, of the middle part, or of the watch case, and which penetrates into the piston 8, and is arranged to push the valve 16 during activation. This probe 19 advantageously comprises a spring arm 190, which bears on this same fixed part, to ensure its retention on the cam 2. At the end of the 5 minutes, the probe 19 leaves the upper track 208 of the projection 202 of the cam 2. and falls back on the lower track 209, and the spring arm 190 pushes it back towards the center of the movement, thus releasing the valve 16.
    The engagement of the pistons 8 is done at the end of each 5-minute period, when the piston 8 arrives radially at the bottom of its respective cylinder, in its position furthest from the center of the movement. The piston 8 is then maneuvered by its respective connecting rod 4 or 5, against the jumper 17, also towards the center of the movement, and this maneuvering by the connecting rod re-engages the valve 16 of this piston 8 in the closed position.
    The movement 200 drives a series of pinions of hours 3, at the rate of a pinion 3 to drive each hour body 30. For example, the movement 200 drives a central brass wheel 309, comprising an annular bearing whose straight internal toothing meshes with straight intermediate steel gears 302; these pinions 302 each mesh with a straight-toothed brass plate 303 which carries a conical intermediate steel wheel 304; the latter meshes with a gear 305 at 45 ° with straight teeth made of steel, which engages a conical 3 hour pinion also made of steel. The hour body 30 is advantageously made of a light alloy, for example an aluminum or titanium alloy. The piston 8 and the valve 16 are preferably made of steel with a DLC coating or the like at their contact surfaces.
    The figures illustrate the preferred variant where the hour bodies 30 are rigid structures, in particular but not limited to metal. A machined tube representing the number or digits 301 of the hour displayed in a given cylinder 10 provides good readability, and is also easier to attach to the 3 hours pinion, by traditional watchmaking means: screwing, riveting, driving, or other. As stated above, this or these digits 301 are also advantageously supplemented by a visual dynamic index 307 intended to be aligned with a static index 308 so as to remove any doubt for the user. Each hour pinion 3 is preferably a bevel pinion, which cooperates with a bevel wheel 34, of axis parallel to the central axis D of the movement 200, directly or as here through a return 305 inclined at 45 ° visible in the figures. The guiding of a block consisting of the hours body 30 and its 3 hours pinion is advantageously carried out by a ball bearing block 22, fixed to the structure 900, or to the caseband or to the case, and which guarantees a good positioning accuracy while ensuring low energy consumption by friction. This ball bearing unit 22 is advantageously combined in a sealed bearing with the at least partially transparent casing 20 which is used to surround both the hours body 30 and the piston 8 which it contains.
    Another variant already mentioned relates to a transparent hour body 30 bearing the hour markings (s), and is rather to be reserved for static timepieces such as clocks where the tubular diameters can be large enough to avoid not alter readability; in fact, the existence of multiple reflections in two coaxial transparent tubular structures of small radius in a watch is liable to disturb the reading of the other minute display at the level of the piston.
    It is understood that a one-off consumption of energy takes place during each change of 5-minute period. The excess energy should be managed during the rest of the time.
    In a first variant, illustrated by FIG. 27, for optimum energy management, the timepiece 1000, which comprises a timepiece movement 200, advantageously comprises a plurality of barrels 50 in parallel and / or in series, the resulting single output 51 of which feeds a multiplier gear 52, which feeds at least one crankshaft 1, which feeds an equalizer 53, which feeds the escapement 54 which cooperates in a conventional manner with the oscillator 55. The parallel setting of the barrels 50 makes it possible to release a large torque for the crankshaft 1. The equalizer winder 53 makes it possible to release a known, controlled and optimal force for the regulator 55.
    In a second variant, illustrated by FIG. 28, and for the same purpose, the timepiece 1000 comprises two energy circuits, one for supplying the crankshaft 1, and the other for supplying power. of the oscillator 55. At least two first barrels 501, or groups of barrels, are in parallel, supplying the crankshaft 1 of the display mechanism 100 via a first multiplier gear 56, which is itself regulated by a first mechanism d 'escapement 57 under the control of a geometric trigger mechanism 58. At least one second barrel 502, or group of barrels, independent, feeds the oscillator 55 through a second multiplier gear 59 and a second mechanism. 'escapement 54. The geometric trigger mechanism 58 of the first multiplier gear 56 is kinematically linked and regulated by the second multiplier gear 59 regulated by the oscillator 55. The advantage of this solution is a little more complex than the first This variant is to ensure that the running precision of the watch does not undergo any running disturbance linked to the operation of the crankshaft 1.
    If the invention is described here in a configuration with twelve cylinders 10, it is understood that it can be implemented, depending on the nature of the desired displays, with a different number of cylinders: 2, 3, 4, 6 , Or other. A coaxial display with a first display and a second display in a single cylinder is also possible.
    Extrapolations can also include one or more cylinders 10 dedicated to different displays, for example, in addition to the hours / minutes display described here, a day / night or AM / PM display in an additional cylinder. Or even a day / night or AM / PM display in an envelope 20 coaxial with the minute piston and the hour body: for example a cylinder10 may include, from its axis towards its periphery: the minute piston 8, the body of '30 hours, a transparent envelope with marking for day / night, another transparent envelope with marking for AM / PM.
    Or even 24-hour displays, dedicating specific colors or decorations to morning displays and others to evening displays; it is then conceivable to keep twelve cylinders 10, with displays differentiated according to the time of day.
    Of course, the first displays 901 and second displays 902 can be reversed, the first then surrounding the second.
    A variant with a transparent tubular double envelope and a polarizer also allows a particular display.
    One can also imagine the lighting of the active cylinder, or of the active cylinders, that of the hours and that of the minutes in the case of the present example.
    Thus, in summary, the invention relates to a watch, comprising a case containing a movement and a display mechanism, arranged between the bottom of the case and the crystal. This display mechanism comprises several distinct elementary displays.
    The case conventionally comprises a middle part, a bezel carrying an upper crystal, and a bottom carrying or not a lower crystal.
    The mobile elementary displays are each housed in an elementary chamber which communicates with the main chamber which contains the movement, the sealing of the box ensuring this of all the chambers. These elementary displays are each housed in a protuberance forming a protuberance of the box, each protuberance comprising an elementary chamber.
    The display of the same horological quantity is distributed over several of these elementary displays.
    Each elementary chamber resembles an engine cylinder, and the envelope of this elementary chamber, constituted by one of these protuberances, comprises at least one transparent part, which is arranged to allow the user to see the position of the corresponding elementary display. A transparent portion of each elementary chamber shell is on the ice side of the timepiece.
    Each elementary display resembles a cage, or a motor piston movable in a cylinder, or a shuttle in a loom of a loom, and circulates in the elementary chamber which is specific to it.
    Each elementary display circulates in its elementary chamber without contact with the internal surface of the protuberance.
    Indeed, the elementary display has its own guide support, rolling bearing on which pivots a rotary elementary display, or guide rod on which slides an elementary display in translation. Thus it is not necessary for the internal surface of the envelope of the elementary chamber, nor the external surface of the elementary display, to be cylindrical. However, an execution of the cylindrical type, with a large radial play to avoid any friction which could penalize the efficiency, is both economical and aesthetic.
    [0100] The supporting structure of this guide support is integral with the movement plate.
    [0101] Each elementary display is driven by a linear movement, or of rotation, inside its elementary chamber.
    The elementary displays are arranged in a star, and more particularly in a full and regular star over 360 °. More particularly, they are arranged around or above the movement.
    [0103] The timepiece resembles an airplane engine in a star, or in a double star (two levels of superimposed stars), and each branch of the star of which has one or more elementary displays. The elementary chambers are arranged radially with respect to a common axis, around which a control mechanism of the timepiece drives wheels or drive linkages of the various display mobiles, by a cam mechanism, and / or crankshafts and connecting rods for linear movements, and / or by a cog for rotary movements.
    [0104] The elementary chambers are arranged in a vee with respect to each other.
    [0105] Each elementary display is arranged to give an indication on only a part of the total range of the horological quantity which is displayed. They are functionally in series, each in turn displaying the instantaneous information.
    [0106] At a given instant, the stroke of each elementary display in its elementary chamber is different from the strokes of the other elementary displays in their respective elementary chambers.
    [0107] The elementary displays have synchronous movements in their respective elementary chambers.
    At a given instant, a single elementary display displays the instantaneous value of the magnitude, and for this purpose the timepiece comprises a trigger mechanism which operates a display indicator, specific to each elementary display, between a active position or inactive position, this display indicator being visible to the user and allowing him to identify simply and quickly the elementary display which displays the instantaneous value of the quantity.
    [0109] A single elementary chamber can contain several elementary displays, of different types, superimposed on one another, in particular nested one inside the other.
    [0110] The watch comprises, for the display of the hours, twelve perforated or transparent rotating cages, which are driven from the movement by a cog.
    [0111] The watch comprises, for the display of the minutes, linear movement pistons, which are driven from the movement by a linkage and cams, by a crankshaft or camshaft system. These pistons circulate inside the rotating cages, the user can see the longitudinal position of each piston.
    [0112] Thus, at a given instant, a rotating cage presents the user with the complete reading of the time, a device indicates that of the cylinders where it reads the minutes (in five-minute increments), and the longitudinal stroke of the piston. in the corresponding chamber determines the reading of the minute within the five-minute period.
    [0113] In a variant, the timepiece comprises, for the display of the minutes, linear movement shuttles, which are driven from the movement by a linkage and cams. These shuttles circulate inside the rotating cages which are partially transparent or perforated, so as to allow the user to see the longitudinal position of each shuttle. And each shuttle caps a display indicator, or is capped by a display indicator, which is controlled by the trigger mechanism to complete a linear stroke with respect to its shuttle, to indicate to the user its activity or inactivity.
    The invention makes it possible to produce a very dynamic, reliable and readable large-complication mechanical display, with a reasonable size which is compatible with a wristwatch.
