Abstract
Description
Technical field
[0001] The present invention relates to a clockwork mechanism for a timepiece, in particular a clockwork mechanism allowing a particularly readable and / or dynamic display. State of the art
[0002] Timepieces, and in particular wristwatches, most often indicate information (for example time information) with one or more indicator members, for example one or more hands. In general, these indicator members have a fixed end and a free end and rotate about an axis passing through their fixed end. The free end generally cooperates with a scale bearing indications, for example time indications. This free end points to these indications. In other cases, the timepiece is devoid of a scale and the wearer of the timepiece deduces the information associated with the indicator members on the basis of the angular position of the free end of one or more indicator members.
[0003] Although very widespread, this reading is not very intuitive and requires training for children or people used to digital displays.
[0004] Timepieces with digital or alphanumeric displays allow for more intuitive reading. However, these timepieces are generally perceived as less qualitative and less aesthetic than timepieces with hands.
[0005] Document CH700615 describes a timepiece in which the hours are indicated by means of mobiles visible through the dial, all the mobiles being turned to a first position with the exception of one mobile turned to a second position. The timepiece comprises a mechanism for turning the mobile occupying the second position at each hour to return it to the first position, and for turning another mobile from the first position to the second position. In this timepiece, the current time is determined at each instant by the location of the mobile occupying the second position.
[0006] Despite the rotation of the mobile bearing the current time, the display remains static for the most part. Brief summary of the invention
[0007] An object of the present invention is to provide a clock mechanism free from the limitations of known clock mechanisms.
[0008] Another aim of the invention is to propose a clock mechanism allowing a particularly dynamic display.
[0009] Another aim of the invention is to propose a clock mechanism allowing a particularly readable display.
[0010] Another object of the invention is to propose an alternative clock mechanism to known displays.
[0011] According to the invention, these aims are achieved in particular by means of the clockwork mechanism according to claim 1, preferred embodiments being given in the dependent claims.
[0012] The clockwork mechanism for a timepiece according to the invention comprises a cam arranged to be driven in rotation about a cam axis, occupying (at least) a number of angular positions equal to one revolution divided by an integer. In one embodiment, this number corresponds to the number of indicator members of the timepiece.
[0013] The clockwork mechanism for a timepiece according to the invention comprises a set of indicator members, each indicator member being arranged to rotate around an indicator member axis.
[0014] The clockwork mechanism for a timepiece according to the invention comprises a set of levers, each lever being associated with an indicator member and being placed in correspondence with one of these angular positions, and a driving mobile, arranged to rotate permanently around a driving mobile axis.
[0015] In the clockwork mechanism for a timepiece according to the invention: - when the cam is in one of its angular positions, it cooperates with a lever, thereby activating a clutch between the driving wheel set and the indicator member of this lever, consequently causing the rotation of this indicator member, this rotation making it possible to indicate information (temporal or non-temporal) to a user of the timepiece, and - when the cam leaves this angular position, the clutch is deactivated, which stops the rotational drive of this indicator member.
[0016] In one embodiment, the cooperation between the cam and the rocker is made in correspondence with a hollow or a protuberance of the cam. In one embodiment, it is preferable for the cam to comprise a hollow rather than a protuberance, in order to reduce or even avoid the risk of breakage of the mechanism according to the invention.
[0017] The watch mechanism according to the invention allows a particularly dynamic display: the information intended for the user of the timepiece is indicated at all times in correspondence with the indicator organ which rotates around its axis at the moment when the user wishes to read this information and during the time associated with this information. For example, the indicator organ associated with the time indication “10 o’clock” rotates for 60 minutes, namely from 10:00 to 11:00 and stops rotating when it is 11:00. At this moment, it is the indicator organ associated with the time indication “11 o’clock” which begins to rotate until 12:00.
[0018] In other words, it is the rotation of the indicator member that allows the user to deduce information intended for the user. Indicator members that do not rotate at the time the user wishes to read information do not allow this information to be deduced.
[0019] The watch mechanism according to the invention also allows a particularly readable display: the user quickly detects the indicator organ which rotates on itself and deduces information from it.
[0020] The clockwork mechanism according to the invention also allows an alternative display to known displays.
[0021] In one embodiment, the indicator member rotates on itself. In one embodiment, the indicator member axis passes through the center of gravity of the indicator member concerned.
[0022] In one embodiment, the cam is arranged to be driven in rotation in a trailing or continuous manner, namely without jumps.
[0023] In another embodiment, the cam is arranged to be rotated in a jerky manner.
[0024] In one embodiment, at least one rocker of the set of rockers (and preferably all the rockers of the set of rockers) comprises a first portion and a second portion substantially parallel to the first portion, the first portion being arranged to cooperate with the cam and the second portion being arranged to carry the indicator member associated with the rocker.
[0025] In one embodiment, at least one flip-flop of the set of flip-flops (and preferably all of the flip-flops of the set of flip-flops) is a single-piece.
[0026] In this context, the adjective “monobloc” indicates that the component to which this adjective refers is made in a monolithic manner.
[0027] In one embodiment, the first part and the second part of at least one rocker of the set of rockers are two separate pieces connected to each other by fixing means.
[0028] In one embodiment, the clockwork mechanism comprises a transformation wheel, arranged to transform a continuous rotational movement into a jerky rotational movement, and to rotate jerkily around a wheel axis, thus occupying different angular positions, the cam being integral with this wheel.
[0029] In this context, the term "mobile" does not necessarily indicate the whole of a wheel with a pinion, but generally indicates a "moving" (adjective) element, for example an element with a rotary movement.
[0030] In one embodiment, the transformation mobile is a Maltese cross, for example a Maltese cross with internal branches (or pointing towards the center of the clockwork mechanism).
[0031] In one embodiment, the cam has the same speed as the transformation wheel.
[0032] In one embodiment, the transformation mobile comprises the cam.
[0033] In one embodiment, the transformation mobile and the cam form a single piece.
[0034] In one embodiment, the indicator members are substantially two-dimensional elements such as discs, polygons, alphanumeric characters or symbols, and / or three-dimensional elements, for example bubbles, semi-bubbles, spherical elements, cubic elements, pyramidal elements, polyhedra, etc.
[0035] In one embodiment, at least one indicator member axis, and preferably the axes of all the indicator members, is (are) perpendicular to a main plane of the driving mobile.
[0036] In one embodiment, at least one indicator member axis, and preferably the axes of all the indicator members, form an angle other than 90° relative to a main plane of the driving mobile.
[0037] In one embodiment, the timepiece mechanism comprises a brake for each indicator member, arranged to brake the rotation of the corresponding indicator member when the rotational drive of this indicator member is stopped.
[0038] In one embodiment, the clockwork mechanism comprises a roller associated with each lever, and in particular with the first part of the lever.
[0039] In one embodiment, the clockwork mechanism comprises a return spring associated with each lever.
[0040] In one embodiment, the clockwork mechanism comprises a stop associated with each lever, to limit a pivoting of the corresponding lever.
[0041] In one embodiment, the clockwork mechanism comprises a single-piece part comprising rocker return springs and stops.
[0042] In one embodiment, the driving mobile is a ring comprising an internal toothing and an external toothing.
[0043] In one embodiment, the transformation mobile, the driving mobile and the single-piece part are at least partially superimposed.
[0044] In one embodiment, the ring is sandwiched between the single-piece part and the transformation mobile.
[0045] In one embodiment, the cam is a first cam, each lever is a first lever, each indicator member is a first indicator member, the information is a first information, and the mechanism comprises a second cam, arranged to cooperate with a first lever or with a second lever, thereby activating a clutch between the driving wheel set and a first indicator member or a second indicator member associated with the second lever, consequently causing the rotation of the first indicator member or the second indicator member, this rotation making it possible to indicate a second information (for example and in a non-limiting manner, GMT information) to a user of the timepiece.
[0046] In one embodiment, the first cam and the second cam are at least partially stacked.
[0047] The invention also relates to a timepiece comprising the mechanism according to the invention. Brief description of the figures

[0049] In the following description provided by way of example, reference will be made, for simplicity, to a clockwork mechanism in which the cam is arranged to be driven in rotation in a jerky manner. The invention, however, is not limited to such a clockwork mechanism but also relates to clockwork mechanisms in which the cam is arranged to be driven in rotation in a trailing manner.
[0050] A first embodiment of the clockwork mechanism 100 according to the invention is visible in Figures 1 to 5.
[0051] In this embodiment, the timepiece mechanism 100 comprises a cam 20 arranged to be driven in rotation about a cam axis A. The cam 20 occupies (at least) a number of angular positions equal to one revolution divided by an integer. In the embodiment of FIGS. 1 to 5, this integer corresponds to the number of indicator members 10 of the timepiece, twelve in the illustrated example.
[0052] In this embodiment, the cam 20 is arranged to be driven in rotation in a jerky manner and it is part of a transformation mobile 70, which forms with it a single piece. In this embodiment, the cam 20 therefore has the same rotation speed as the transformation mobile 70.
[0053] The transformation mobile 70 is arranged to transform a continuous rotational movement into a jerky rotational movement, and to rotate jerkily around a mobile axis, thus occupying different angular positions. In the embodiment of FIGS. 1 to 5, the mobile axis corresponds to the axis of the cam A.
[0054] In the embodiment of figures 1 to 5, the transformation wheel 70 is a Maltese cross, for example a Maltese cross with internal branches (or pointing towards the center of the watch mechanism), which cooperates in a known manner with a finger 81 carried by a driving wheel 80 of the basic movement (for example the movement making it possible to count the seconds, minutes and / or hours) of the timepiece comprising the watch mechanism 100.
[0055] In other embodiments (not illustrated), the cam 20 is integral with this transformation mobile 70.
[0056] In other embodiments (not illustrated), the cam 20 does not necessarily have the same speed as the transformation mobile 70.
[0057] Each indicator member 10 is arranged to rotate about an indicator member axis B. In the embodiment of Figures 1 to 5, the indicator member axis B passes through the center of gravity of the relevant indicator member 10.
[0058] In the embodiment of Figures 1 to 5, the indicator members 10 are semi-bubbles or semi-spherical elements. The invention, however, is not limited to indicator members 10 having these shapes but also includes other indicator members 10 having another three-dimensional shape (for example bubbles, spherical elements, cubic elements, pyramidal elements, polyhedra, etc.) and also substantially two-dimensional elements such as for example discs, polygons, alphanumeric characters or symbols.
[0059] At least one indicator member 10 may carry one (or more) decorative pattern(s) 11, for example a relief pattern, as can be seen in FIG. 3, in order to further increase the dynamism and / or the readability of the information indicated when the indicator member 10 rotates on itself.
[0060] The clockwork mechanism 100 also comprises a set of levers 30, better visible in FIG. 2, each lever 30 being associated with an indicator member 10 and being placed in correspondence with one of the possible angular positions occupied by the cam 20.
[0061] As can be better seen in Figures 4 and 5, in the illustrated embodiment, each lever 30 comprises a first part 301 and a second part 302 substantially parallel to the first part 301, the first part 301 being arranged to cooperate with the cam 20 and the second part 302 being arranged to carry the indicator member 10 associated with the lever 30 (and possibly an intermediate gear 60 as well, if present).
[0062] In the illustrated embodiment, the first part 301 and the second part 302 are two separate parts connected to each other by fixing means. In another embodiment (not illustrated), at least one rocker of the set of rockers (and preferably all the rockers of the set of rockers) is in one piece, i.e. produced monolithically.
[0063] The timepiece mechanism 100 also comprises a driving wheel set 40, arranged to rotate continuously around a driving wheel set axis. In the embodiment of FIGS. 1 to 5, this driving wheel set 40 is a ring which rotates around the same cam axis A. As can be seen in FIG. 2, this driving wheel set 40 comprises an internal toothing 402 and an external toothing 401, and the internal toothing 402 cooperates (directly or indirectly, for example via an intermediate wheel 51) with a wheel 50 of the basic movement of the timepiece, which also rotates continuously around its axis (which in the illustrated example corresponds to the cam axis A).
[0064] In the clockwork mechanism 100 for a timepiece according to the invention, when the cam 20 is in one of its angular positions, it cooperates with the lever 30 which is also in correspondence with this angular position, thus activating a clutch between the driving wheel set 40 and the indicator member 10 of this lever 30, consequently causing the rotation of this indicator member 10, this rotation making it possible to indicate information (temporal or non-temporal) to a user of the timepiece.
[0065] In the embodiment of figures 1 to 5, the cooperation between the cam 20 and the rocker 30 is carried out in correspondence with a hollow 21 of the cam 20. In other embodiments, it is carried out in correspondence with a protuberance (not illustrated) of the cam 20.
[0066] The watch mechanism 100 therefore allows a particularly dynamic display: the information is indicated to the user of the timepiece thanks to the rotation of the indicator member (or indicator members) 10 in correspondence with which the clutch is activated, the other indicator members not rotating. In other words, the information is indicated at each instant in correspondence with the indicator member 10 which is rotating at the moment when the user wishes to read this information. In other words again, the indicator members 10 which are not rotating (they are stationary) at the moment when the user wishes to read information do not allow this information to be deduced.
[0067] The clockwork mechanism according to the invention also allows a particularly readable display: the user quickly detects the indicator member 10 which rotates on itself and deduces information from it.
[0068] When the cam 30 leaves this angular position, the clutch is deactivated, which stops the rotational drive of the indicator member 10 rotating on itself.
[0069] The clutch is one of various types of clutch mechanisms, including one of vertical clutch mechanisms, horizontal clutch mechanisms, and swing gear clutch mechanisms, known per se in the art, and which will not be described herein.
[0070] As a non-limiting example, the embodiment of Figures 1 to 5 uses a horizontal clutch between the external toothing 401 of the ring 40 and a toothing of a pinion 12 carried by the axis B of the indicator member 10, via an intermediate gear 60, as can be seen in Figure 4. Of course, the presence of the intermediate gear 60 is not essential, and the pinion 12 could mesh directly with the external toothing 401 of the ring 40. If an intermediate gear 60 is present, it is not necessarily limited to two wheels as in the example illustrated, but it may comprise only one wheel or a number of wheels other than two.
[0071] In one embodiment, at least one indicator member 10 is arranged to rotate in only one direction of rotation (i.e., either clockwise or counterclockwise). In another embodiment, at least one indicator member 10 is arranged to be able to rotate in both directions of rotation, i.e., clockwise and at other times counterclockwise. In another embodiment, at least one indicator member 10 rotates in only one direction of rotation and at least one other indicator member 10 rotates in both directions of rotation.
[0072] In the embodiment of Figures 1 to 5, each rotating indicator member 10 provides information on one hour of the current time. In another embodiment, the indicator members 10 can provide information on the current minutes and / or seconds. In this case, they will not necessarily be sixty in number because of their size, but they may be a number of a divisor of sixty, for example six in number.
[0073] In the embodiment of Figures 1 to 5, the indicator members are equidistant between two neighboring indicator members. In other embodiments, the distance between one indicator member 10 and the adjacent one may vary.
[0074] In the embodiment of Figures 1 to 5, the indicator members 10 are arranged substantially in a circle. In other embodiments, they are arranged in a semicircle, in an arc of a circle, or according to another geometry.
[0075] In one embodiment, the indicator member 10 rotates with a rotation speed of between 1 and 30 seconds per revolution, for example between 5 and 20 seconds per revolution, in particular 12 seconds per revolution. Of course, these ranges and these values should not be considered as limiting: with the aid of possible intermediate wheels, reductions in the speed of a wheel of the basic movement can be carried out in a known manner, also giving other values.
[0076] In one embodiment, the timepiece mechanism 100 comprises a brake 13 for each indicator member 10, arranged to brake the rotation of the corresponding indicator member 10 when the rotational drive of this indicator member is stopped. In one embodiment, this brake 13 also makes it possible to limit or even cancel unwanted movements of the associated indicator member 10 when the user moves the timepiece comprising the timepiece mechanism 100.
[0077] In one embodiment, the brake 13 comprises a tenon 131 connected to a whip 132, as can be seen for example in FIG. 1.
[0078] In the embodiment of figures 1 to 5, the clockwork mechanism 100 comprises a roller 320 associated with each lever 30, visible for example in figure 5. This roller 320 is used in a known manner to replace sliding friction with rolling friction during contact of a lever 30 with the cam 20.
[0079] In the embodiment of Figures 1 to 5, the clockwork mechanism 100 comprises a return spring 91 (better visible in Figures 4 and 5) associated with each lever 30, which improves the cooperation between the lever 30 and the cam 20.
[0080] In the embodiment of figures 1 to 5, the clockwork mechanism 100 also comprises a stop 92 associated with each lever 30, better visible in figure 4, to limit a pivoting of the corresponding lever 30.
[0081] In the embodiment of Figures 1 to 5, the clockwork mechanism 100 comprises a single-piece part 90, clearly visible in Figure 2, comprising both lever return springs 91 and stops 92. In other embodiments, the single-piece part 90 comprises either the lever return springs 91 or the stops 92. In other embodiments, neither the lever return springs 91 nor the stops 92 belong to a single-piece part.
[0082] In the embodiment of Figures 1 to 5, the transformation mobile 70, the ring 40 and the single-piece part 90 are (at least partially) superimposed and the ring 40 is sandwiched between the single-piece part 90 and the transformation mobile 70, as is clearly visible in Figure 4.
[0083] In the embodiment of figures 1 to 5, the axes B of all the indicator members 10 are perpendicular to a main plane xy (visible in figure 1) of the driving mobile 40.
[0084] In the embodiment of Figures 1 to 5, the axes B of all the indicator members 10 are also perpendicular to the corresponding rocker 30, in particular to at least one of the parts 301, 302 of each rocker 30.
[0085] The second embodiment illustrated in Figures 6 to 8 differs from that of Figures 1 to 5 at least in that the axes B' of all the indicator members 10 form an angle other than 90° with respect to a main plane of the driving mobile xy and / or with respect to the corresponding rocker 30, in particular at least one of the parts 301, 302 of each rocker 30.
[0086] To do this, the pinion 12 comprises a toothing arranged to cooperate with the external toothing 401 of the ring 40 (via an intermediate gear 60 if necessary) taking into account this non-perpendicularity.
[0087] The second embodiment illustrated in Figures 9 to 11 differs from that of Figures 1 to 5 at least in that the mechanism comprises a second cam 20', arranged to cooperate with a first lever or with a second lever (not illustrated), thereby activating a clutch between the driving wheel set 40 and a first indicator member 10 or a second indicator member (not illustrated) associated with the second lever 20', consequently causing the rotation of the first indicator member 10 (or of the second indicator member), this rotation making it possible to indicate a second piece of information (for example and in a non-limiting manner, GMT information) to a user of the timepiece.
[0088] In one embodiment, the first cam 20 and the second cam 20' are at least partially stacked, as seen for example in FIG. 11.
[0089] Although in the embodiment of figures 9 to 11, the axis B of each indicator member 10 is perpendicular to the main plane xy of the driving mobile 40 and / or to the corresponding rocker 30, this characteristic should not be considered as limiting: in fact, in this embodiment, this axis may be non-perpendicular to the main plane xy of the driving mobile 40 and / or to the corresponding rocker 30, as in the embodiment of figures 6 to 8.
[0090] The clockwork mechanism 100 according to the invention can be used in a timepiece (such as for example a wristwatch) as an alternative or in addition to known displays. Reference numbers used in the figures
